affecting our operations and financial position, see Management's Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, of this report and Note 1 - Summary of Significant Accounting Policies under Part II, Item 8, of this report. BUSINESS SEGMENTS Ameren has three reportable segments: Ameren Missouri, Ameren Illinois, and Merchant Generation. See Note 18 - Segment Information under Part II, Item 8, of this report for additional information on reporting segments. RATES AND REGULATION Rates The rates that Ameren Missouri and Ameren Illinois are allowed to charge for their utility services significantly influence the results of operations, financial position, and liquidity of these companies and Ameren. The electric and natural gas utility industry is highly regulated. The utility rates charged to Ameren Missouri and Ameren Illinois customers are determined, in large part, by governmental entities, including the MoPSC, the ICC, and FERC. Decisions by these entities are influenced by many factors, including the cost of providing service, the prudency of expenditures, the quality of service, regulatory staff knowledge and experience, economic conditions, public policy, and social and political views.
Decisions made by these governmental entities regarding rates are largely outside of Ameren Missouri's and Ameren Illinois' control. These decisions, as well as the regulatory lag involved in filing and getting new rates approved, could have a material impact on the results of operations, financial position , and liquidity of Ameren, Ameren Missouri and Ameren Illinois. Rate orders are
also subject to appeal, which creates additional uncertainty as to the rates Ameren Missouri and Ameren Illinois are ultimately allowed to charge for their services.
Beginning in 2012, the effect of regulatory lag on Ameren Illinois' electric distribution business is expected to be mitigated through the use of the formula ratemaking regulatory framework established under the IEIMA. The ICC regulates rates and other matters for Ameren Illinois and ATXI. The MoPSC regulates rates and other matters for Ameren Missouri. The FERC regulates Ameren Missouri, Ameren Illinois, Genco and ATXI as to their ability to charge market-based rates for the sale and transmission of energy in interstate commerce and various other matters discussed below under General Regulatory Matters. About 49% of Ameren's electric and 16% of its natural gas operating revenues were subject to regulation by the MoPSC in the year ended December 31, 2011. About 30% of Ameren's electric and 84% of its natural gas revenues were subject to regulation by the ICC in the year ended December 31, 2011. Wholesale revenues for Ameren Missouri, Ameren Illinois, Genco and AERG are subject to FERC regulation, but not subject to direct MoPSC or ICC regulation.
A meren Missouri ElectricAbout 99% of Ameren Missouri's electric operating revenues were subject to regulation by the MoPSC in the year ended December 31, 2011 with the remainder subject to FERC regulation. In July 2011, the MoPSC issued an order approving an increase for Ameren Missouri in annual revenues for
electric service of $173 million, including $52 million related to an increase in normalized net fuel costs above the net fuel costs included in base rates previously authorized by the MoPSC in its May 2010 electric rate order. The revenue increase was based on a 10.2% return on equity, a capital structure composed of 52.2%
common equity, and a rate base of $6.6 billion. The rate changes became effective on July 31, 2011. The MoPSC order approved the continued use of Ameren Missouri's
vegetation management and infrastructure cost tracker, pension and postretirement benefit cost tracker, and FAC at the current 95% sharing level. The MoPSC order shortened the FAC recovery an d refund period from 12 months to eight months. Additionally, the MoPSC order provided for a tracking mechanism for uncertain income tax positions. In February 2012, Ameren Missouri filed a request with the MoPSC to increase its annual revenues for electric service by $376 million. Included in this requested increase was a $103 million increase in normalized net fuel costs above the net fuel costs included in base rates previously authorized by the MoPSC in its July 2011 electric rate order. Absent initiation of this general rate proceeding, 95% of this amount would have been reflected in rate adjustments implemented under Ameren Missouri's FAC. The request also included recovery of the costs associated with energy efficiency programs under the MEEIA, including energy efficiency investments, a storm cost tracking mechanism, plant-in-service accounting treatment, and recovery of other costs
incurred to provide systemwide reliability improvements for customers, among other items. The electric rate increase request was based on a 10.75% return on equity, a capital structure composed of 52% common equity, an aggregate electric rate base of $6.8 billion, and a test year ended September 30, 2011, with certain pro forma adjustments expected through the anticipated true-up date of July 31, 2012. A decision by the MoPSC in this proceeding is expected in December 2012. FERC regulates the rates charged and the terms and conditions for electric transmission services. Each RTO separately files a regional transmission tariff for approval by FERC. All transmission service within that RTO is then 6 operating Table of Contentssubjected to that tariff. As a member of MISO, Ameren Missouri's transmission rate is calculated in accordance with the MISO OATT. The transmission rate is updated in June of each year; it is based on Ameren Missouri's filings with FERC. This rate is not directly charged to Missouri retail customers, because in Missouri the MoPSC includes transmission-related costs in setting bundled retail rates.
Natural Gas All of Ameren Missouri's natural gas operating revenues were subject to regulation by the MoPSC in the year ended December 31, 2011. In January 2011, the MoPSC approved a stipulation and agreement that allowed Ameren Missouri to increase annual natural gas revenues by $9 million. The new rates became effective on February 20, 2011. As part of the stipulation and agreement, Ameren Missouri agreed not to file a separate natural gas rate increase request before December 31, 2012; however, Ameren Missouri can file a combined natural gas and electric rate case before that date. Further, this agreement does not prevent Ameren Missouri from filing to recover infrastructure replacement costs through an ISRS during this moratorium. The return on equity to be used by Amer en Missouri for purposes of the ISRS tariff filing is 10%. If certain criteria are met, Ameren Missouri's natural gas rates may be adjusted without a traditional rate proceeding. PGA clauses permit prudently incurred natural gas costs to be passed directly to the consumer.
The ISRS also permits prudently incurred natural gas infrastructure replacement costs to be passed directly to the consumer. For additional information on Missouri rate matters, including Ameren Missouri's pending electric rate case, and Ameren Missouri's 2009, 2010 and 2011 electric rate orders and related court appeals and regulatory proceedings, see Results of Operations and Outlook in

A meren Illinois ElectricAbout 99% of Ameren Illinois' electric operating revenues were subject to regulation by the ICC in the year ended December 31, 2011 with the remainder subject to FERC regulation. Under the Illinois Customer Choice Law, all electric customers in Illinois may choose their own electric energy provider. However, Ameren Illinois is required to serve as the provider of last resort (POLR) for electric customers within its territory who have not chosen an alternative retailelectric supplier. Ameren Illinois' obligation to provide POLR electric service varies by customer size. Ameren Illinois is not required to offer fixed-priced electric service to customers with electric demands of 400 kilowatts or greater, as the market for service to this group of customers has been declared competitive. Power and related procurement costs incurred by Ameren Illinois are passed directly to its customers through a cost recovery mechanism. In October 2011, the IEIMA was enacted into law and became effective immediately. Certain amendments to the IEIMA became effective on December 30, 2011. On January 3, 2012, Ameren Illinois elected to participate in
the performance-based fo rmula ratemaking process established pursuant to the IEIMA by filing initial performance-based formula rates with the ICC. The initial
filing, based on 2010 recoverable costs and expected net plant additions for 2011 and 2012, will result in new electric delivery service rates in October 2012. Pending ICC approval, the initial filing will result in a decrease in Ameren Illinois revenues for electric delivery service of
$19 million, on an annualized basis. Ameren Illinois anticipates making an update filing by May 1, 2012, based on 2011 costs and expected net plant additions for 2012, that would result in new electric delivery service rates on January 1, 2013. By choosing to opt-in, Ameren Illinois will participate in a performance-based formula process for determining rates that will provide for the recovery of actual costs of electric delivery service that are prudently incurred, reflect the utility's actual regulated capital structure and include a formula for calculating the return on equity component of the cost of capital. The equity component of the formula rate will be equal to the average for the applicable calendar year of the monthly average yields of 30-year United States treasury bonds plus 590 basis points for 2012 and 580 basis points thereafter. Ameren Illinois'
actual return on equity relating to electric delivery service will be subject to a collar adjustment on earnings in excess of 50 basis points above or below its allowed return. Beginning in 2012, the law provides for an annual reconciliation of revenues to costs prudently and reasonably incurred. This annual revenue reconciliation along with the collar adjustment, if necessary, will be
collected from or refunded to customers in a subsequent year.Ameren Illinois will also be subject to five performance standards under the IEIMA whereby the failure to achieve the standards will result in a reduction in its allowed return on equity calculated under the formula. The performance standards include improvements in service reliability to reduce both the frequency and duration of outages, improvements in customer satisfaction scores, reduction in the number of estimated bills, and a reduction in uncollectible accounts expense. The IEIMA provides for return on equity penalties totaling up to 30 basis points in 2013 through 2015, 34 basis points in 2016 through 2018 and 38 basis points in 2019 through 2022 if the performance standards are not met. The formula ratemaking process is effective until the end 7of 2017, but could be extended by the Illinois General Assembly Table of Contentsfor an additional five years. The formula ratemaking processwould also terminate if the average residential rate increases by more than 2.5% annually from June 2011 through May 2014.
Between 2012 and 2021, Ameren Illinois will be required to invest $625 million in capital expenditures incremental to Ameren Illinois' average electric delivery capital expenditures for c alendar years 2008 through 2010 to modernize its distribution system. Such investments are expected to encourage economic development and create an estimated 450 additional jobs within Illinois.
Ameren Illinois is subject to monetary penalties if 450 additional jobs are not created during the peak program year. Also, Ameren Illinois will be required to contribute $1 million annually for certain nonrecoverable customer assistance programs, up to a total of $10 million through 2021, for as long as Ameren Illinois participates in the formula ratemaking process. Ameren Illinois will also be required to make a one-time $7.5 million nonrecoverable donation to the Illinois Science and Energy Innovation Trust in 2012, as well as an approximate $1 million annual donation to the same trust for as long as it participates in the formula ratemaking process. Ameren Illinois has a tariff rider to recover the costs of asbestos-related litigation claims, subject to the following terms: 90% of cash expenditures in excess of the amount included in base electric rates are to be recovered from a trust fund that was established when Ameren acquired IP. At December 31, 2011, the trust fund balance was
$23 million, including accumulated interest. If cash expenditures are less than the amount in base rates, Ameren Illinois will contribute 90% of the difference to the fund. Once the trust fund is depleted, 90% of allowed cash expenditures in excess of base rates will be recovered through charges assessed to customers under the tariff rider. Following the Ameren Illinois Merger, this rider is applicable only for claims that occurred within IP's historical service territory. Similarly, the rider will permit recovery only from customers within IP's historical service territory. As a member of MISO, Ameren Illinois' transmission rate is calculated in accordance with the MISO OATT.
The transmission rate is updated in June of each year based on Ameren Illinois' filings with FERC. This rate is charged directly to wholesale customers and alternative
retail electric suppliers. Retail customers who have not chosen an alternative retail electric supplier pay the transmission rate through a rider mechanism.
Natural Gas All of Ameren Illinois' natural gas operating revenues were subject to regulation by the ICC in the year ended December 31, 2011. In January 2012, the ICC issued a rate order that approved an increase in Ameren Illinois' annual revenues for natural gas delivery service of $32 million. The revenue increase was based on a 9.06% return on equity, base of approximately $1 billion. The rate order was based on a 2012 future test year. The rate changes became effective on January 20, 2012. In February 2012, the ICC denied rehearing requests by Ameren Illinois and an intervenor related to the granted return on equity. If certain criteria are met, Ameren Illinois' natural gas rates may be adjusted without a traditional rate proceeding. PGA clauses permit prudently incurred natural gas costs to be passed directly to the consumer. Also, Ameren Illinois has approval from the ICC to use cost recovery mechanisms for energy efficiency programs and bad debt expense not recovered in base rates.
For additional information on Illinois rate matters, including the IEIMA and the ICC's January 2012 natural gas rate order, see Results of Operations and Outlook in
Management's Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, Quantitative and Qualitative Disclosures About Market Risk under Part II, Item 7A, and Note 2 - Rate and
Regulatory Matters, and Note 15 - Commitments and Contingencies under Part II, Item 8, of this report. Merchant Generation Merchant Generation reve nues are determined by market conditions and contractual arrangements. We
expect the Merchant Generation fleet of assets to have 5,503 megawatts of capacity available for the 2012 peak summer electrical demand. This capacity reflects the closure of the four units at Genco's Meredosia and Hutsonville energy centers and the sale of the Columbia CT during 2011, as well as the sale of the Medina Valley energy center in early 2012. As discussed below, Genco and AERG sell all of their power and capacity to Marketing Company through power supply agreements.
Marketing Company attempts to optimize the value of those assets and to mitigate risks through a variety of hedging techniques, including wholesale sales of capacity and energy, retail sales in the non-rate-regulated Illinois market, spot market sales primarily in MISO and PJM, and financial transactions, including options and other derivatives. Marketing Company enters into long-term and short-term contracts. Marketing Company's counterparties include cooperatives, municipalities, residential, commercial and industrial customers, power marketers, MISO, PJM and investor-owned utilities, including Ameren Illinois. For additional information on Marketing Company's hedging activities and Marketing Company's sales to Ameren Illinois, see Outlook in
Management's Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7 and Note 7 - Derivative Financial Instruments and Note 14 - Related Party Transactions under Part II, Item 8, of this report.
8a capital structure composed of 53.3% common equity, and a rate Table of ContentsGeneral Regulatory Matters Ameren Missouri and Ameren Illinois must receive FERC approval to enter into various transactions, including to issue short-term debt securities and to conduct certain acquisitions, mergers, and consolidations involving electric utility holding companies having a value in excess
of $10 million. In addition, these Ameren utilities must receive authorization from the applicable state public utility regulatory agency to issue stock and long-term debt securities (with maturities of more than 12 months) and to conduct mergers, affiliate transactions, and various other activities. Genco and AERG are subject to FERC's j urisdiction when they issue any securities and when they enter into certain other transactions, including those listed
above. Ameren Missouri, Ameren Illinois, ATXI, Genco and AERG are also subject to mandatory reliability standards, including cybersecurity standards, adopted by FERC to ensure the reliability of the bulk power electric system.
These standards are developed and enforced by NERC pursuant to authority given to it by the FERC. If the Ameren Companies were found not to be in compliance with any of these mandatory reliability standards they may incur substantial monetary penalties and other sanctions. Under PUHCA 2005, FERC and any state public utility regulatory agencies may access books and records of Ameren and its subsidiaries that are determined to be relevant to costs incurred by Ameren's rate-regulated subsidiaries with respect to jurisdictional rates. PUHCA 2005 also permits the MoPSC and the ICC to request that FERC review cost allocations by Ameren Services to other Ameren companies. Operation of Ameren Missouri's Callaway energy center is subject to regulation by the NRC. Its facility operating license expires on June 11, 2024. In December 2011, Ameren Missouri submitted a license extension application with the NRC to exte nd the plant's operating license to 2044. There is no date by which the NRC must act on this relicensing request. Ameren Missouri's Osage hydroelectric energy center and Ameren Missouri's Taum Sauk pumped-storage hydroelectric energy center, as licensed projects under the Federal Power Act, are subject to FERC regulations affecting, among other things, the general operation and maintenance of the projects. The license for Ameren Missouri's Osage hydroelectric energy center expires on March 30, 2047. In June 2008, Ameren Missouri filed a relicensing application with FERC to operate its Taum Sauk pumped-storage hydroelectric energy ce nter for another 40 years. The existing FERC license expired on June 30, 2010. On July 2, 2010, Ameren Missouri received a license extension that allows Taum Sauk to continue operations until FERC issues a new license. FERC is reviewing the relicensing application. A FERC order is expected in 2012 or 2013. Ameren Missouri cannot predict the ultimate outcome of the order. Ameren Missouri's Keokuk energy center and its dam, in the Mississippi River between Hamilton, Illinois, and Keokuk, Iowa, are operated under For additional information on regulatory matters, see Note 2 - Rate and Regulatory Matters and Note 15 - Commitments and Contingencies under Part II, Item 8, of this report, which include a discussion about the December 2005 breach of the upper reservoir at Ameren
Missouri's Taum Sauk pum ped-storage hydroelectric energy center. Environmental Matters Certain of our operations are subject to federal, state, and local environmental statutes or regulations relating to the safety and health of personnel, the public, and the environment. These environmental statutes and regulations include requirements for identification, generation, storage, handling, transportation, disposal, recordkeeping, labeling, reporting, and emergency response in connection with hazardous and toxic materials; safety and health standards; and environmental protection requirements, including standards and limitations relating to the discharge of air and water pollutants and the management of waste and byproduct materials. Failure to comply with those statutes or regulations could have material adverse effects on us. We could be subject to criminal or civil penalties by regulatory agencies or we could be ordered by the courts to pay private parties. Except as indicated in this report, we believe that we are in material compliance with existing statutes and regulations.
In addition to existing laws and regulations, including the Illinois MPS, which govern our facilities, the EPA is developing numerous new envir onmental regulations that will have a significant impact on the electric utility industry. These regulations could be particularly burdensome for certain companies, including Ameren, Ameren Missouri and Genco, that operate coal-fired energy centers. Significant new rules proposed or promulgated since the beginning of 2010 include the regulation of greenhouse gas emissions; revised national ambient air quality standards for SO and NO emissions; the CSAPR, which requires further reduction of SO and NO emissions from power plants; a regulation governing management of CCR and coal ash impoundments; the MATS, which reduces emissions of mercury, metals, and acid gases from power plants; revised NSPS for particulate matter, SO, and NO emissions from new sources; and new regulations under the Clean Water Act that could require significant capital expenditures such as new water intake structures or cooling towers at our energy centers. The EPA also plans to propose an
additional rule, applicable to new and existing electric generating units, governing NSPS and emission guidelines for greenhouse gas emissions. These new regulations may be litigated, so the timing of their implementation is uncertain, as evidenced by the stay of the CSAPR by the United States Court of Appeals for the District of Columbia on December 30, 2011. Although many details of these future regulations are unknown, the combined effects of the new and proposed environmental
regulations may result in significant capital expenditures and/or increased operating costs over the next five to ten 22 2 x 2x 9authority granted by an Act of Congress in 1905. years for Ameren, Ameren Missouri and Genco. Actions required to ensure that our Table of Contentsfacilities and operations are in compliance with environmental laws and regulations could be prohibitively expensive. If they are, these regulations could require us to close or to significantly alter the operation of our energy centers, which could have an adverse effect on our results of operations, finan cial position, and liquidity, including the impairment of plant assets. Failure to comply with environmental laws and regulations might also result in the imposition of fines, penalties, and
injunctive measures. For additional discussion of environmental matters, including NO, SO, and mercury emission reduction requirements, global climate change, remediation efforts, and a discussion of the EPA's allegations of violations of the Clean Air Act and Missouri law in connection with projects at certain coal-fired energy centers, see Liquidity and Capital Resources in Management's Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, and Note 15 - Commitments and Contingencies under Part II, Item 8, of this report. TRANSMISSION AND SUPPLY OF ELECTRIC POWER Ameren owns an integrated transmission system that comprises the transmission assets of Ameren Missouri, Ameren Illinois and ATXI. Ameren also operates two balancing authority areas, AMMO (which includes Ameren Missouri), and AMIL (which includes Ameren Illinois, ATXI, Genco excluding EEI and Genco's Elgin CT facility, and AERG). During 2011, the peak demand was 8,831 megawatts in AMMO and 9,605 megawatts in
AMIL. The Ameren transmission system directly connects with 15 other balancing authority areas for the exchange of electric energy. Ameren Missouri, Ameren Illinois and ATXI are transmission-owning members of MISO. Transmission service on the Ameren transmission systems is provided pursuant to the terms of the MISO OATT on file with FERC. EEI operates its own balancing authority area and its own transmission facilities in southern Illinois. The EEI transmission system is directly connected to MISO, the Tennessee Valley Authority, and Louisville Gas and Electric Company. EEI's generating units are dispatched separately from those of Ameren Missouri, Genco and
AERG.FERC, in its order issued in May 2011, approved transmission rate incentives for the Illinois Rivers project and the Big Muddy project, which will be developed by ATXI or ATX. In December 2011, MISO approved the Illinois Rivers project as well as the Spoon River and Mark Twain projects. The total investment in these three MISO-approved projects is expected to be more than $1.2 billion through 2019, with potential investment of approximately $750 million from 2012 to 2016. All four projects are in Missouri and Illinois. Construction will begin first on the Illinois Rivers project. The Big Muddy project is currently being evaluated for inclusion in MISO's 2012 expansion plan. The Ameren Companies and EEI are members of x2system in all or portions of Missouri, Illinois, Arkansas, Kentucky, Tennessee, North Carolina, South Carolina, Georgia, Mississippi, Alabama, Louisiana, Virginia, Florida, Oklahoma, Iowa, and Texas. As a result of the Energy Policy Act of 2005, owners and operators of the bulk electric power system are subject to mandatory reliability standards promulgated by NERC and its regional entities, such as SERC, which are enforced by FERC. The Ameren Companies must follow these standards, which are in place to ensure the reliability of the bulk electric power system. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report for additional information. Ameren Missouri Ameren Missouri's electric supply is obtained primarily from its own generation. Factors that could cause Ameren Missouri to purchase power include, among other things, absence of sufficient owned generation, energy center outages, the fulfillment of renewable energy portfolio requirements, the failure of suppliers to meet their power supply obligations, extreme
weather conditions, and the availability of power at a cost lower than the cost of generating it. Ameren Missouri continues to evaluate its longer-term needs for new baseload and peaking electric generation capacity. Ameren Missouri's integrated resource plan filed with the MoPSC in February 2011 included the expectation that new baseload generation capacity would be required between 2020 and 2030. Because of the significant time required to plan, acquire permits for, and build a baseload power plant, Ameren Missouri continues to study future plant alternatives, as well as energy
efficiency programs that could help defer new plant construction. To prepare for the long-term need for baseload capacity, and to prepare for potentially more stringent environmental regulation of coal-fired energy centers, which could lead to the retirement of current baseload assets, Ameren Missouri is taking steps to preserve options to meet future demand. These steps
include seeking improvements in regulatory treatment of energy efficiency investments, evaluating potential sites for natural gas-fired generation, and pursuing an early site permit for an additional unit at its existing nuclear plant site. Ameren Missouri's pursuit of an early site permit is dependent upon enactment of a legislative framework ensuring cost recovery.

markets operated by MISO. The power and related procurement costs incurred by Ameren Illinois are passed directly to its customers through a cost recovery mechanism. The IPA administers a RFP process that procures Ameren Illinois' expected supply obligation. Since the start of this process, the ICC has approved the outcomes of multiple electric power procurement RFPs for energy, capacity, and renewable energy credits covering different time periods. A portion of the electric power supply required for Ameren Illinois to satisfy its distribution customers' requirements is purchased in the RFP process administered by the IPA from Marketing Company on behalf of Genco and AERG. In addition, as part of the 2007 Illinois Electric Settlement Agreement, Ameren Illinois entered into financial contracts with Marketing Company (for the benefit of Genco and AERG) to lock in energy prices for 400 to 1,000 megawatts annually of its round-the-clock power requirements during the period June 1, 2008, through December 31, 2012, at the market prices relevant at that time. These financial contracts do not include capacity, are not load-following products, and do not involve the physical delivery of energy. See Note 2 - Rate and Regulatory Matters, Note 14 - Related Party Transactions and Note 15 - Commitments and Contingencies under Part II, Item 8, of this report for additional information on power procurement in Illinois. Merchant Generation Genco and AERG have entered into power supply agreements with Marketing Company whereby Genco and AERG sell, and Marketing Company purchases, all of the capacity and energy available from Genco's and AERG's generation energy centers and the associated energy. These power supply agreements continue through December 31, 2022, and from year to year thereafter unless either party elects to terminate the agreement by providing the other party with no less than six months' advance written notice. EEI and Marketing Company have entered into a power supply agreement for EEI to sell all of its capacity and energy to Marketing Company. This agreement expires on May 31, 2016. All of Genco's, AERG's and EEI's energy centers compete for the sale of energy and capacity in the competitive energy markets through Marketing Company.

(a)(b)(c)(a)(b)(c)(a)(b)(c)(a)(b)(c)CoalAmeren, Ameren Missouri and Genco have agreements in place to purchase a portion of their coal needs and to transport it to electric generating energy centers through 2019. Ameren, Ameren Missouri and Genco expect to enter into additional contracts to purchase coal from time to time. Coal supply agreements typically have an initial term of up to five years, with about 20% of the contracts expiring annually. Ameren Missouri has an ongoing need for coal to serve its native load customers and pursues a price hedging strategy consistent with this requirement. Merchant Generation's forward coal requirements are dependent on the volume of power sales that have been contracted. Merchant Generation strives to achieve increased margin certainty by aligning its fuel purchases with its power sales.
Ameren burned 39 million tons (Ameren Missouri - 22 million, Genco - 13 million) of coal in 2011. See Part II, Item 7A - Quantitative and Qualitative Disclosures About Market Risk of this report for additional information about coal supply contracts. About 98% of Ameren's coal (Ameren Missouri - 97%, Genco - 99%) is purchased from the Powder River Basin in Wyoming. The remaining coal is typically purchased from the Illinois Basin. Ameren, Ameren Missouri and Genco have a goal to maintain coal inventory consistent with their risk management policies.
Inventory may be adjusted because of changes in burn or uncertainties of supply due to potential work stoppages, delays in coal deliveries, equipment breakdowns, and other factors. In the past, deliveries from the Powder River Basin have occasionally been restricted because of rail maintenance, weather, and derailments. As of December 31, 2011, coal inventories for Ameren Missouri were at targeted levels and were at or above targeted levels for Genco. Disruptions in coal deliveries could cause Ameren, Ameren Missouri and Genco to pursue a strategy that could include reducing sales of power during low-margin periods, buying higher-
cost fuels to generate required electricity, and purchasing power from other sources.
Nuclear The steps in the process to provide nuclear fuel generally involve the mining and milling of uranium ore to produce uranium concentrates, the conversion of uranium concentrates to uranium hexafluoride gas, the enrichment of that gas, and the fabrication of the enriched uranium
hexafluoride gas into usable fuel assemblies. Ameren Missouri has entered into uranium, uranium conversion, enrichment, and fabrication contracts to procure the fuel supply for its Callaway nuclear plant. Fuel assemblies for the 2013 spring refueling at Ameren Missouri's Callaway energy center are scheduled for manufacture and delivery to the plant during 2012. Ameren Missouri also has agreements or inventories to price-hedge approximately 92%, 82%, and 47% of Callaway's 2013, 2014 and 2016 refueling requirements, respectively. Ameren Missouri has uranium (concentrate
and hexafluoride) inventories and supply contracts sufficient to meet all of its uranium and conversion requirements through at least 2014. Ameren Missouri has enriched uranium inventories and enrichment supply Table of Contents contracts sufficient to satisf y enrichment requirements through 2013. Fuel fabrication services are under contract through 2014. Ameren Missouri expects to enter into additional contracts to purchase nuclear fuel. As a member of Fuelco, Ameren Missouri can join with other member companies to increase its purchasing power, enhance diversification and pursue opportunities for volume discounts. The Callaway nuclear plant normally requires refueling at 18-month intervals. The last refueling was completed in November 2011. There is no refueling scheduled for 2012 and 2015. The nuclear fuel markets are competitive, and prices can be volatile; however, we do not anticipate any significant problems in meeting our future supply requirements. Natural Gas Supply for Generation To maintain gas deliveries to gas-fired generating units throughout the year, especially during the summer peak demand, Ameren's portfolio of natural gas supply resources includes firm transportation capacity and firm no-notice storage capacity leased from interstate pipelines. Ameren Missouri and Genco primarily use the interstate pipeline systems of Panhandle Eastern Pipe Line Company, Trunkline Gas Company, Natural Gas Pipeline Company of America, and Mississippi River
Transmission Corporation to transport natural gas to generating units. In addition to physical transactions, Ameren uses financial instruments, including some in the NYMEX futures market and some in the OTC financial
markets, to hedge the price paid for natural gas.Ameren Missouri's and Genco's natural gas procurement strategy is des igned to ensure reliable and immediate delivery of natural gas to their generating units. This is accomplished by optimizing transportation and storage options and minimizing cost and price risk through various supply and price-hedging agreements that allow access to multiple gas pools, supply basins, and storage services. As of December 31, 2011, Ameren Missouri had price-hedged about 12% and Genco had price-hedged 32% of its expected natural gas supply requirements for generation in 2012. Renewable Energy Illinois and Missouri have enacted laws requiring electric utilities to include renewable energy resources in their portfolios. Illinois requires renewable energy resources to equal or exceed 2% of the total electricity that each electric utility supplies to its eligible retail customers as of June 1, 2008, increasing to 15% by June 1, 2015, and to 25% by June 1, 2025. Ameren
Illinois has procured renewable energy credits under the IPA-administered procurement process to meet the renewable energy portfolio requirement through May 2012. In December 2010, Ameren Illinois entered into a 20-year agreement with renewable energy suppliers and will begin receiving renewable energy credits under the agreement starting in June 2012, to help supplement these requirements. Approximately 50% of the 2012
renewable energy requirement will be met through this
agreement. In 2011, Ameren Illinois procured approximately 6% of its total electricity from renewable energy resources. In Missouri, utilities are required to purchase or generate from renewable energy sources electricity equaling at least 2% of native load sales, with that percentage increasing to at least 15% by 2021, subject to a 1% limit on customer rate impacts. At least 2% of each renewable energy portfolio requirement must be derived from solar energy. Ameren Missouri expects to satisfy the nonsolar requirement through 2017 with existing
renewable generation in its current fleet along with a 15-year 102 MW power purchase agreement with a wind farm operator in Iowa that became effective in 2009 and the landfill gas project discussed below. Currently, Ameren Missouri expects to meet the solar energy requirement through the purchase of solar-generated renewable energy credits; however, Ameren Missouri is studying other options for compliance. In 2011, Ameren Missouri purchased or generated approximately 3% of its native load sales from renewable energy resources. In September 2009, Ameren Missouri announced an agreement with a landfill owner to install CTs at a landfill site in Maryland Heights, Missouri, which is expected to
generate approximately 15 megawatts of electricity by burning methane gas collected from the landfill. The CTs (known as the Maryland Heights energy center) are expected to begin generating power in 2012. Ameren Missouri signed a 20-year supply agreement with the landfill owner to purchase methane gas. Energy Efficiency Ameren's rate-regulated utilities have implemented energy efficiency programs to educate and help their customers become more efficient users of energy. The MEEIA, enacted in 2009, established a regulatory framework that, among other things, allows electric utilities to recover costs related to MoPSC-approved energy efficiency programs. The law requires the MoPSC to ensure that a utility's financial incentives are aligned with helping customers use energy more efficiently, to provide timely cost recovery, and to provide earnings opportunities associated with cost-effective energy efficiency programs. Missouri does not have a law mandating energy efficiency standards. In January 2012, Ameren Missouri made its initial filing with the MoPSC under the MEEIA. This filing proposes a three-year plan that includes a portfolio of energy efficiency programs along with a cost recovery mechanism. If the proposal is approved, beginning in January 2013, Ameren Missouri plans to invest
$145 million over three years for the proposed energy efficiency programs. A decision by the MoPSC in this proceeding is anticipated in th e second quarte r of 2012. Ameren Missouri anticipates that the impacts of the MoPSC's decision in this MEEIA filing will be included in rates set under its pending electric service rate case that was filed on February 3, 2012, which has an anticipated true-up date of July 31, 2012. Ameren Missouri's pending electric rate case includes an annual revenue increase of Table of Contents14 $81 million relating to its planned portfolio of energy efficiency programs included in its MEEIA filing. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report for additional information. Illinois has enacted a law requiring Ameren Illinois to offer energy efficiency programs. The law also allows recovery mechanisms of the programs' costs. The ICC has issued orders approving Ameren Illinois' electric and natural gas energy efficiency plans as well as cost recovery mechanisms by which program costs can be
recovered from customers. In addition, over a ten-year period, Ameren Illinois will invest an estimated $625 million to upgrade and modernize its transmission and distribution infrastructure in accordance with the IEIMA.
As part of these upgrades, Ameren Illinois expects to invest $360 million to install smart meters, which could enable customers to improve efficiency. NATURAL GAS SUPPLY FOR DISTRIBUTION Ameren Missouri and Ameren Illinois are responsible for the purchase and delivery of natural gas to their gas utility customers. Ameren Missouri and Ameren Illinois
develop and manage a portfolio of gas supply resources. These include firm gas supply under term agreements with producers, interstate and intrastate firm transportation capacity, firm storage capacity leased from interstate pipelines, and on-system storage facilities to maintain gas deliveries to customers throughout the year and especially during peak demand. Ameren Missouri and Ameren Illinois primarily use the Panhandle Eastern Pipe Line Company, the Trunkline Gas Company, the Natural Gas Pipeline Company of America, the Mississippi River Transmission Corporation, the Northern Border Pipeline Company, and the Texas Eastern Transmission Corporation interstate pipeline systems to transport natural gas to their systems. In addition to physical transactions, financial instruments, including those entered into in the NYMEX futures market and in the OTC financial markets, are used to hedge the price paid for natural gas. See Part II, Item 7A - Quantitative and Qualitative Disclosures About Market Risk of this report for additional information about natural gas supply contracts. Natural gas purchase costs are passed on to customers of Ameren Missouri and Ameren Illinois under PGA clauses, subject to prudency reviews by the MoPSC and the ICC. As of December 31, 2011, Ameren Missouri had price-hedged 90%, and Ameren Illinois had price-hedged 87%, of its expected natural gas supply requirements for distribution in 2012. For additional information on our fuel and purchased power supply, see Results of Operations, Liquidity and Capital Resources and Effects of Inflation and Changing Prices in Management's Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, of this report.

INDUSTRY ISSUES We are facing issues common to the electric and natural gas utility industry and the merchant electric generation industry. These issues include: continually developing and complex environmental laws, regulations and issues, including air and water quality standards, mercury emissions standards, and likely greenhouse gas limitations and ash mana gement requirements; political and regulatory resistance to higher rates, especially in a difficult economic environment; the potential for change s in laws, regulation, and policies at the state and federal level, including those resultin g from election c y cles;access to, and uncertainty in, the capital and credit markets;the potential for more intense competition in generation, supply and distribution, including new technologies; pressure on customer growth and usage in light of current economic condition s and energy efficiency initiatives;the potential for reregulation in some states, which could cause electric distribution companies to build or acquire generation facilities and to purchase less power from electric generating companies such as Genco and AERG; changes in the structure of the industry as a result of changes in federal and state laws, including the formation of merchant generators, independent transmission entities and RTOs; increases, decreases and volatility in power prices due to the balance of supply and demand and
mar ginal fuel costs; the availability of fuel and increases or decreases in fuel prices; the availability of qualified labor and material, and rising costs; regulatory lag; decreased or negative free cash flows due to rising infrastructure investments and re gulator y frameworks; public concern about the sitin g of new facilities; aging infrastructure and the need to construct new power generation, transmission and distribution
facilities;legislation or proposals for programs to encourage or mandate energy efficiency and renewable sources of power; public concerns about nuclear plant operation and decommissioning and the disposal of nuclear waste; and consolidation of electric and natural g as companies.

These documents are also available through an Internet website maintained by the SEC (www.sec.gov). Ameren also uses its website as a channel of distribution
of material information relating to the Ameren Companies.
Financial and other material information regarding the Ameren Companies is routinely posted and accessible at Ameren's website. The Ameren Companies also make available free of charge through Ameren's website the charters of Ameren's board of directors' audit and risk committee, human resources committee, nominating and corporate governance committee, finance committee, nuclear oversight and environmental committee, and public policy committee; the corporate governance guidelines; a policy regarding communications to the board of directors; a policy and procedures with respect to related-person transactions; a code of ethics for principal executive and senior financial officers; a code of business conduct applicable to all directors, officers and employees; and a director nomination policy that applies to the Ameren Companies. The information on Ameren's website, or any other website referenced in this report, is not incorporated by reference into this report. Investors should review carefully the following risk factors and the other information contained in this report.
The risks that the Ameren Companies face are not limited to those in this section. There may be additional risks and uncertainties (either currently unknown or not currently believed to be material) that could adversely affect the results of operations, financial position, and liquidity of the Ameren Companies. See Forward-Looking Statements above and Outlook in Ma nagement's Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, of this report. The Ameren Companies are subject to extensive regulation of their businesses, which could adversely affect their results of operations, financial position, and liquidity. The Ameren Companies are subject to, or affected by, extensive federal, state, and local regulation. This extensive regulatory framework, some but not all of which is more specifically identified in the following risk factors, regulates, among other matters, the electric and natural gas industries; rate and cost structure of utilities;
operation of ITEM 1A.RISK FACTORS. nuclear power facilities; construction and operation of generation, transmission and distribution facilities; acquisition, disposal, depreciation and amortization of assets and facilities; transmission reliability; and present or prospective wholesale and retail competition. The Ameren Companies must address in their business planning and management of operations the effects of existing and proposed laws and regulations and potential changes in the regulatory framework, including initiatives by federal and state legislatures, RTOs, utility regulators, and taxing authorities. Significant changes in the nature of the regulation of the Ameren Companies' businesses could require changes to their business planning and management of their businesses and could adversely affect their results of operations, financial position, and liquidity. Failure of the Ameren Companies to obtain adequate rates or regulatory approvals in a timely manner, failure to obtain necessary licenses or permits from regulatory authorities, new or changed laws, regulations, standards, interpretations, or other legal requirements, or increased compliance costs could adversely impact the Ameren Companies' results of operations, financial po sition, and liquidity. The electric and natural gas rates that Ameren Missouri and Ameren Illinois are allowed to charge are determined through regulatory proceedings, which are subject to appeal, and are subject to legislative actions, which are largely outside of their control. Any events that prevent Ameren Missouri or Ameren Illinois from recovering their respective costs or from earning appropriate returns on their investments could have a material adverse effect on results of operations, financial position, and liquidity. The rates that Ameren Missouri and Ameren Illinois are allowed to charge for their utility services significantly influence the results of operations, financial position, and liquidity of these companies and Ameren. The electric and natural gas utility industries are highly regulated. The utility rates charged to Ameren Missouri and Ameren
Illinois customers are determined, in large part, by governmental entities, including the MoPSC, the ICC, and FERC. Decisions by these entities are influenced by many factors, including the cost of providing service, the prudency of expenditures, the quality of service, regulatory staff knowledge and experience, economic conditions, public policy, and social and political views. Decisions made by these governmental entities regarding rates are largely outside of Ameren Missouri's and Ameren Illinois' control. Regulatory lag involved in filing and getting new rates approved could have a material adverse effect on our results of operations, financial
position, and liquidity. Rate orders are also subject to appeal, which creates additional uncertainty as to the rates Ameren Missouri and Ameren Illinois will ultimately be allowed to charge for their services. Ameren Missouri electric and natural gas utility rates and Ameren Illinois natural gas utility rates are typically established in regulatory proceedings that take up to 11 months to complete. Rates established in those Table of Contentsproceedings for Ameren Missour i are primarily based on historical costs and revenues. Rates established in those proceedings for Ameren Illinois may be based on historical or estimated future costs and revenues. Thus, the rates a utility is allowed to charge may not match its costs at any given time. Rates include an allowed return on investments by the regulators. Although rate regulation is premised on providing a reasonable opportunity to earn a reasonable rate of return on invested capital, there can be no assurance that the applicable regulatory commission will judge all the costs of Ameren Missouri and Ameren Illinois to have been prudently incurred or that the regulatory process in which rates are determined will always result in rates that will produce full recovery of such costs or an adequate return on those investments.
In 2011, for example, the MoPSC issued an electric rate order that disallowed $89 million of costs incurred related to the rebuilding of the Taum Sauk energy center. As a result, Ameren and Ameren Missouri each recorded a 2011 pretax charge to earnings of $89 million. During periods of rising costs and investments or declining retail usage, Ameren Missouri and Ameren Illinois may not be able to earn the allowed return established by their regulators. This could result in deferral or elimination of planned capital investments. A period of increasing rates for our customers could result in additional regulatory and legislative actions, as well as competitive and political pressures, which could have a material adverse effect on our results of operations, financial position, and liquidity. By choosing to participate in the performance-based formula ratemaking process established pursuant to the IEIMA, Ameren Illinois' return on equity will be directly correlated to yields on United States treasury bonds. Additionally, Ameren Illinois will be subject to an annual ICC prudence review and will be required to achieve performance objectives, increase capital spending levels, and meet job creation targets, which if not successfully completed or achieved could have a material adverse effect on its results of operations, financial position, and liquidity. On January 3, 2012, Ameren Illinois elected to participate in the performance-based formula ratemaking process established pursuant to the IEIMA by submitting its initial filing with the ICC for its electric distribution business. The ICC will annually review Ameren Illinois' performance-basedrate filings under the IEIMA for
reasonableness and prudency. The ICC could conclude that Ameren Illinois' incurred costs were not prudently incurred and thus disallow recovery of such costs annually. Additionally, the e quity component of the formula rate will be equal to the average for the applicable calendar year of the monthly average yields of 30-year United States treasury bonds plus 590 basis points for 2012 and 580 basis points th ereafter. Therefore, Ameren Illinois' annual return on equity will be directly correlated to yields on United States treasury bonds, which are outside of Ameren Illinois' control. reduction in the company's allowed return on equity calculated under the formula. The IEIMA provides for return on equity penalties totaling 30 basis points in 2013 through 2015, 34 basis points in 2016 through 2018, and 38 basis points in 2019 through 2022 if the performance standards are not met.
Between 2012 and 2021, Ameren Illinois will be required to invest $625 million in capital expenditures incremental to Ameren Illinois' average electric delivery capital expenditures for c alendar years 2008 through 2010 to modernize its distribution system. Ameren Illinois is subject to monetary penalties if 450 additional jobs in Illinois are not created during the peak program year. The formula ratemaking process would terminate if the average residential rate increases by more than 2.5%
annually from June 2011 through May 2014. The average residential rate includes generation service, which is outside of Ameren Illinois' control, as Ameren Illinois is required to purchase all of its power through procurement processes administered by the IPA. If the performance-based formula rate process is terminated, Ameren Illinois would be required to establis h future rates using a traditional rate proceeding with the ICC, which may not result in rates that produce a full or timely recovery of costs or an adequate return on investments. Unless extended, the IEIMA formula ratemaking process expires in 2017. Energy conservation and energy efficiency efforts could have a material adverse effect on the Ameren Companies' results of operations, financial position, and liquidity.
Regulatory and legislative bodies have proposed or introduced requirements and incentives to reduce energy consumption. Conservation and energy efficiency programs are designed to reduce energy demand. Unless there is a regulatory solution, declining usage will result in an underrecovery of fixed costs at our rate-regulated business. A reduction in energy demand could have a
material adverse effect on the Ameren Companies' results of operations, finan cial position, and liquidity. We are subject to various environmental laws and regulations that require significant capital expenditures or could result in closure of facilities, could increase our operating costs, and could materially adversely influence or limit our results of operations, financial position, and liquidity, or expose us to fines and liabilities. We are subject to various environmental laws and regulations enforced by federal, state and local authorities. From the beginning phases of siting and development to the ongoing operation of existing or new electric generating, transmission and distribution facilities and natural gas storage, transmission and distribution facilities, our activities involve compliance with diverse environmental laws and regulations. These laws and regulations address emissions, impacts to air, land and water, noise, protected natural and cultural resources (such as wetlands, 18 Ameren Illinois will also be subject to performance standards. Failure to achieve the standards will result in a Table of Contentsendangered species and other protected wildlife, and archeological and historical resources), and chemical and waste handling. Complex and lengthy processes are required to obtain approvals, permits, or licenses for new, existing, or modified facilities. Additionally, the use and handling of various chemicals or hazardous materials (including wastes) requires release prevention plans and emergency response procedures. We are also subject to liability under environmentallaws for remediating environmental contamination of property now or formerly owned by us or by our predecessors, as well as property contaminated by hazardous substances that we generated. Such sites include MGP sites and third-party sites, such as landfills.
Additionally, private individuals may seek to enforce environmental laws and regulations against us and could allege injury from exposure to hazardous materials.
In addition to existing laws and regulations, including the Illinois MPS that applies to our energy centers in Illinois, the EPA is developing numerous new environmental regulations that will have a significant impact on the electric utility industry. These regulations could be particularly burdensome for certain companies, including Ameren, Ameren Misso uri and Genco, that operate coal-fired plants. These new regulations may be litigated, so the timing of their ultimate implementation is uncertain, as evidenced by the stay of the CSAPR by the United States Court of Appeals for the District of Columbia on December 30, 2011. Ameren also may be subject to risks in connection with changing or conflicting interpretations of existing laws and regulations. The EPA is engaged in an enforcement initiative to determine whether coal-fired power plants failed to comply with the re quirements of the NSR and NSPS provisions under the Clean Air Act when the plants implemented modifications. Following the issuance of a Notice of Violation, in January 2011, the Department of Justice on behalf of the EPA filed a complaint against Ameren Missouri in the United States District Court for the Eastern District of Missouri. The EPA's complaint alleges that in performing projects at its Rush Island coal-fired energy center, Ameren Missouri violated provisions of the Clean Air Act and Missouri law. In January 2012, the United States District Court granted, in part, Ameren Missouri's motion to dismiss various aspects of the EPA's penalty claims. The EPA's claims for injunctive relief, including to require the installation of pollution control equipment, remain. At presen t, the complaint does not include Ameren Missouri's other coal-fired energy centers, but the EPA has issued Notices of Violation under its NSR enforcement initiative against the company's Labadie, Merame c, and Sioux coal-fired energy centers. Litigation of this matter could take many years to resolve. An outcome in this matter adverse to Ameren Missouri could require substantial capital expenditures and the payment of substantial penalties, neither of which can be determined at this time. Such expenditures could affect unit retirement and replacement decisions. Ameren, Ameren Missouri and Genco have incurred and expect to incur significant costs related to
environmental compliance and site remediation. New environmental regulations, future environmental
regulations, volunta ry compliance guidelines, enforcement initiatives, or legislation could result in a significant increase in capital expenditures and operating costs, decreased revenues, increased financing requirements, penalties, fines, or closure of facilities for Ameren, Ameren Missouri and Genco. Actions required to ensure that our facilities and operations are in compliance with environmental laws and regulations could be prohibitively expensive. As a result, environmental regulations could require us to close or to significantly alter the operation of our energy centers, which could have an adverse effect on our results of operations, financial position, and liquidity, including the impairment of plant assets. Although costs incurred by Ameren Missouri to ensure its facilities are in compliance with environmental laws and regulations would be eligible for recovery in rates over time, subject to MoPSC approval in a rate proceeding, there is no similar cost recovery mechanism for Genco or for Ameren's Merchant Generation business segment. We are unable to predict the ultimate impact of these matters on our results of
operations, financial position, and liquidity. Future limits on greenhouse gas emissions would likely require Ameren, Ameren Missouri and Genco to incur significant increases in capital expenditures and operating costs, which, if excessive, could result in the closures of coal-fired energy centers, impairment of assets, or otherwise materially adversely affect our results of operations, financial position, and liquidity. State and federal authorit ies, including the United States Congress, have considered initiatives to limit greenhouse gas emissions and to address global climate change. Potential impacts from any climate change legislation or regulation could vary, depending upon proposed CO emission limits, the timing of
implementation of those limits, the method of distributing any allowances, the degree to which offsets are allowed and available, and provisions for cost-containment measures, such as a "safety valve" provision that provides a maximum price for emission allowances. As a result of our diverse fuel portfolio, our emissions of greenhouse gases vary among our energy centers, but coal-fired power plants are significant sources of CO.
The enactment of a climate change law could result in a significant rise in household costs and rates for electricity could rise significantly. The burden could fall particularly hard on electricity consumers and upon the economy in the Midwest because of the region's reliance on electricity generated by coal-fired power plants. Future federal and state legis lation or regulations that mandate limits on the emission of greenhouse gases would likely result in significant increases in capital expenditures and operating costs, which, in turn, could lead to increased liquidity needs and higher financing costs. Moreover, to the extent Ameren Missouri requests 2 2 19 recovery of these costs Table of Contentsthrough rates, its regulators might deny some or all of, or defer timely recovery of, these costs. Excessive costs to comply with future legislation or regulations might force Ameren, Ameren Missouri and Genco to close some coal-fired energy centers earlier than planned, which could lead to possible impairment of assets and reduced revenues. As a result, mandatory limits could have a material adverse impact on Ameren's, Ameren Missouri's, and Genco's results of operations, financial position, and liquidity. The construction of, and capital improvements to, Ameren's, Ameren Missouri's and Ameren Illinois' electric and natural gas utility infrastructure as well as to Ameren's and Genco's merchant generation facilities involve substantial risks. These risks include escalating costs, unsatisfactory performance by the projects when completed, the inability to complete projects as scheduled, cost disallowances by regulators and the inability to earn a reasonable return on invested capital, any of which could result in higher costs and the closure of facilities. Over the next five years, the Ameren Companies will incur significant capital expenditures to comply with
existing and known environmental regulations and to make investments in their electric and natural gas utility infrastructureand their merchant generation facilities. The Ameren Companies estimate that they will incur up to $8.3 billion (Ameren Missouri - up to $3.6 billion; Ameren Illinois - up to $3.3 billion; Genco - up to $0.4 billion; other - up to $1.0 billion) of capital expenditures during the period 2012 through 2016. These expenses include construction expenditures, capitalized interest or allowance for funds used during construction, compliance with environmental standards, and compliance with the requirements of the IEIMA. Investments in Ameren's regulated operations are expected to be recoverable from ratepayers, but are subject to prudency reviews and regulatory lag. The recoverability of amounts expended in merchant generation operations will depend upon market prices for capacity and energy. The ability of the Ameren Companies to complete facilities under construction successfully, and to complete future projects within established estimates, is contingent upon many variables and subject to substantial risks. These variables include, but are not limited to, project management expertise and escalating costs for materials, labor, and environmental compliance. Delays in obtaining permits, shortages in materials and qualified labor, suppliers and contractors who do not perform as required
under their contracts, changes in the scope and timing of projects, the inability to raise capital on favorable terms, or other events beyond our control that could occur may
materially affect the schedule, cost, and performance of these projects. With respect to capital spent for pollution control equipment, there is a risk that electric generating plants will not be permitted to continue to operate if pollution control equipment is not installed by prescribed deadlines or does not perform as expected. Should any such construction efforts be unsuccessful, the Ameren Companies could be subject to additional costs and to the loss of their investment in the project or facility. The Ameren Companies may also be required to purchase electricity for their customers until the projects are completed. All of these risks may have a material adverse
effect on the Ameren Companies' results of operations, financial position, and liquidity. Our counterparties may not meet their obligations to us. We are exposed to the risk that counterparties to various arrangements who owe us money, credit, energy, coal, or other commodities or services will not be able to perform their obligations or, with respect to our credit facilities, will fail to honor their commitments. Should the counterparties to commodity arrangements fail to perform, we might be forced to replace or to sell the underlying commitment at then-current market prices. Should the lenders under our credit facilities fail to perform, the level of borrowing capacity under those arrangements would decrease, unless we were able to find replacement lenders to assume the nonperforming lender's commitment. In such an event, we might incur losses, or our results of operations, financial position, and liquidity could otherwise be adversely affected. Certain of the Ameren Companies have obligations to other Ameren Companies or other Ameren subsidiaries as a result of transactions involving energy, coal, other commodities and services, borrowing from the money
pools, and as a result of hedging transactions. If one Ameren entity failed to perform under any of these arrangements, other Ameren entities might incur losses.
Their results of operations, financial position, and liquidity could be adversely affected, resulting in the nondefaulting Ameren entity being unable to meet its obligations, including to unrelated third parties. Increasing costs associated with our defined benefit retirement and postretirement plans, health care plans, and other employee benefits could materially adversely affect our results of operations, financial position, and liquidity. We offer defined bene fit retirement and postretirement plans that co ver substantially all of our employees. Assumptions related to future costs, returns on investments, interest ra tes, and other actuarial matters have a significant impact on our earnings and funding requirements. Ameren expects to fund its pension plans at a level equal to the greater of the pension expense or the legally required minimum contribution. Considering Ameren's assumptions at December 31, 2011, its investment performance in 2011, and its pension funding policy, Ameren expects to make annual contributions of
$90 million to $150 million in each of the next five years, with aggregate estimated contributions of $580 million. We expect Ameren Missouri's, Ameren Illinois', and Genco's portion of the future funding requirements to be 51%, 33%, and 12%, respectively. These amounts are
estimates. They Table of Contentsmay change with actual investment performance, changes in interest rates, changes in our assumptions, changes in government regulations, and any voluntary contributions. In addition to the costs of our retirement plans, the costs of providing health care benefits to our employees and retirees have increased in recent years. We believe that our employee benefit co sts, including costs of health care plans for our employees and former employees, will continue to rise. The increasing costs and funding requirements associated with our defined benefit retirement plans, health care plans, and other employee benefits could increase our financing needs and otherwise materially adversely affect our results of operations, financial po sition, and liquidity. Our electric generating, transmission and distribution facilities are subject to operational risks that could materially adversely affect our results of operations, financial position, and liquidity. The Ameren Companies' financial performance depends on the successful operation of electric generating, transmission, and distribution facilities. Operation of electric generating, transmission, and distribution facilities involves many risks, including: facility shutdowns due to operator error or a failure of equipment or processes; lon g er-than-anticipated maintenance outa ges; older generating equipment may require significant expenditures to keep it operatin g at peak efficienc y; disruptions in the delivery of fuel or lack of adequate inventories, including ultra-low-sulfur coal used for Ameren Missouri's compliance with environmental
regulations; lack of water for cooling plant operations; labor disputes; inability to comply with regulatory or permit requirements, including those relating to environmental contamination; disruptions in the delivery of electricity, including impacts on us or our customers; handling and storage of fossil-fuel combustion byproducts, such as CCR; unusual or adverse weat her conditions, including severe storms, drou ghts, floods and tornados; a workplace accident that might result in injury or loss of life, extensive property damage, or environmental
dama g e;cybersecurity risk, including loss of operational control of our energy centers and our electric and natural gas transmission and distribution systems and/or loss of data, such as utility customer data, account information, and intellectual property through insider or outsider actions; catastrophic events such as fires, explosions, pandemic health events, or other similar occurrences; limitations on amounts of insurance available to cover losses that might arise in connection with operating our electric generating, transmission, and distribution
facilities; and We are subject to federal regulatory compliance and proceedings, which increase our risk of regulatory penalties and other sanctions. The Energy Policy Act of 2005 increased FERC's civil penalty authority for violation of FERC statutes, rules, and orders, including FERC Reliability Standards. FERC can impose penalties of $1 million per violation per day. Under the Energy Policy Act of 2005, the Ameren Companies, as owners and operators of bulk power transmission
systems and/or electric generation facilities, are subject to mandatory NERC reliability standards, including cybersecurity standards.
Compliance with these mandatory reliability standards may subject the Ameren Companies to higher operating costs and may result in increased capital expenditures. If the Ameren Companies were found not to be in compliance with these mandatory reliability standards or other FERC statutes, rules and
orders, the Ameren Companies could incur substantial monetary penalties and other sanctions, which could
adversely affect our results of operations, financial position, and liquidity. Our natural gas distribution and storage activities involve numerous risks that may result in accidents and other operating risks and costs that could materially adversely affect our results of operations, financial position, and liquidity. Inherent in our natural gas distribution and storage activities are a variety of hazards and operating risks, such as leaks, accidental explosions, mechanical problems and cybersecurity risks, which could cause substantial financial losses. In addition, these risks could result in serious injury to employees and nonemployees, loss of human life, significant damage to property, environmental pollution, and impairment of our operations, which in turn could lead to substantial losses for us. In accordance with customary industry practice, we maintain insurance a gainst some, but not all, of these risks and losses. The location of distribution lines and storage facilities near populated areas, including residential areas, commercial business centers, industrial
sites, and other public ga thering places, could increase the level of damages resulting from these risks. The occurrence of any of these events not fully covered by insurance could materially adversely affect our results of operations, financial position, and liquidity. Even though agreements have been reached with the state of Missouri and the FERC, the breach of the upper reservoir of Ameren Missouri's Taum Sauk pumped-storage hydroelectric energy center could continue to have a material adverse effect on Ameren's and Ameren Missouri's results of operations, liquidity, and financial condition. In December 2005, there was a breach of the upper reservoir at Ameren Missouri's Taum Sauk pumped-storage hydroelectric energy center. This resulted in significant flooding in the local area, which damaged a state park. other unanticipated operations and maintenance expenses and liabilities.
Table of Contents22 Ameren Missouri settled with FERC and the state of Missouri all issues associated with the December 2005 Taum Sauk incident. Ameren Missouri had liability insurance coverage for the Taum Sauk incident, subject to certain limits and deductibles. In June 2010, Ameren Missouri sued one of its liability insurance providers claiming the insurance company breached its duty to indemnify Ameren Missouri for the losses experienced from the incident. Ameren's and Ameren Missouri's results of operations, financial position and liquidity could be adversely affected if Ameren Missouri's remaining liability insurance claims of $68 million as of December 31, 2011, are not paid by
insurers. Ameren Missouri requested the recovery of all costs of enhancements, or costs that would have been incurred absent the breach, related to the rebuilding of the Taum Sauk energy center in excess of amounts recovered from property insurance. In its July 2011 electric rate order, the MoPSC disallowed Ameren Missouri's request. Consequently, in 2011, Ameren Missouri recorded a pretax charge to earnings of $89 million. Ameren Missouri has appealed this disallowance to the Missouri Court of Appeals, Western District. Ameren Missouri cannot
predict the ultimate outcome of its appeal. Until Ameren's remaining liability insurance claims and litigation are resolved, we are unable to determine the total impact the breach could have on Ameren's and Ameren Missouri's results of operations, financial position, and liquidity beyond those amounts already recognized. Genco's and AERG's electric energy centers must compete for the sale of energy and capacity, which exposes them to price risks. All of Genco's and AERG's energy centers compete for the sale of energy and capacity in the competitive energy markets. To the extent that electricity generated by these energy centers is not under a fixed-price contract to be sold, the revenues and results of operations of these Merchant Generation subsidiaries generally depend on the prices that can be obtained for energy and capacity in Illinois and adjacent markets by Marketing Company. Market prices for energy and capacity may fluctuate substantially, sometimes over relatively short periods of time, and at other times experience sustained increases or decreases. Demand for electricity and fuel can fluctuate dramatically, creating periods of substantial undersupply or oversupply. During periods of oversupply, prices might be depressed. Also, at times legislators or regulators with jurisdiction over wholesale and retail energy commodity and transportation rates may impose price limitations, bidding rules, and other mechanisms to address volatility and other issues in these markets. For power products sold in advance, contract prices are influenced both by market conditions and by contract terms such as damage provisions, credit support requirements, and the number of available counterparties interested in contracting for the desired forward period.
Depending on differences between market factors at the time of contracting versus current conditions, Marketing Company's contract portfolio may have average contract prices greater than or less than current market prices, including at the expiration of the contracts, which could significantly affect Ameren's and Genco's results of operations, financial condition and liquidity. Market prices for power have decreased over the past three years. During 2012, the market price for power for delivery in the current year has declined below 2011 levels because of factors such as declining natural gas prices and the stay of the CSAPR. Any unhedged forecasted generation will be exposed to market prices at the time of sale. As a result, any new physical or financial power sales may be at price levels lower than previously experienced and lower than the value of existing hedged
sales.Among the factors that could influence such prices (all of which are beyond our control to a significant
degree) are: current and future delivered market prices for natural gas, coal, and related transportation costs; current and forward prices for the sale of electricit y;current and future prices for emission allowances that may be required to operate the fossil fuel-fired electric energy centers in compliance with environmental laws and permits; the extent of additional supplies of electric energy from current competitors or new market entrants; the regulatory and market structures developed for evolving Midwest energy markets, including a capacit y market in MISO; changes enacted by the Illinois legislature, the ICC, the IPA, or other government agencies with respect to power procurement procedures; the potential for reregulation of generation in some states; future pricing for, and availability of, services on transmission systems, and the effect of RTOs and export energy transmission constraints, which could limit our abilit y to sell ener gy in our markets; the growth rate or decline in electricity usage as a result of population changes, regional economic conditions, and the implementation of energy-
efficienc y and conservation pro g rams;climate conditions in the Midwest market and major natural disasters; and environmental laws and re gulations or delays in their effective dates.
Table of ContentsAmeren Missouri's ownership and operation of a nuclear energy center creates business, financial, and waste disposal risks. Ameren Missouri's ownership of the Callaway energy center subjects it to the risks of nuclear generation, which include the following: The NRC has broad authority under federal law to impose licensing and safety requirements for nuclear energy centers. In the event of noncompliance, the NRC has the authority to impose fines or shut down a unit, or both, depending upon its assessment of the severity of the situation, until compliance is achieved. Revised safety requirements promulgated from time to time by the NRC could necessitate substantial capital expenditures at nuclear energy centers such as Ameren Missouri's. In addition, if a serious nuclear incident were to occur, it could have a material but in determinable adverse effect on Ameren Missouri's result s of operations, financial condition, and liquidity. A major incident at a nuclear energy center anywhere in the world could cause the NRC to limit or prohibit the operation or relicensing of any domestic nuclear unit. An incident at a nuclear energy center anywhere in the world also could cause the NRC to impose additional conditions or requirements on the
industry, which could increase costs and result in
additional capital expenditures. For example, the earthquake in 2011 that affected nuclear plants in Japan is expected to result in regulatory changes in the United States that may impose additional costs on all United States nuclear plants. potential harmful effects on the environment and human health resulting from the operation of nuclear facilities and the storage, handling and disposal of radioactive materials; the lack of a permanent waste stora ge site; limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with t he Callaway energy center or other United States nuclear operations; uncertainties with respect to contingencies and assessment amounts if insurance coverage is inadequate; public and governmental concerns over the adequacy of securit y at nuclear ener gy centers; uncertainties with respect to the technological and financial aspects of decommissioning nuclear energy centers at the end of their licensed lives (Ameren Missouri has submitted an application with the NRC to extend the Callaway energy center's operating license from 2024 to 2044
); limited availabilit y of fuel suppl y; and costly and extended outages for scheduled or unscheduled maintenance and refuelin g.Our energy risk management strategies may not be effective in managing fuel and electricity procurement and pricing risks, which could result in unanticipated liabilities or increased volatility in our earnings and cash flows. We are exposed to changes in market prices for natural gas, fuel, power, emission allowances, renewable energy credits, and transmission congestion. Prices for natural gas, fuel, power, emission allowances and renewable energy credits may fluctuate substantially over relatively short periods of time, and at other times exhibit sustained increases or decreases, and expose us to commodity price risk. We use short-term and long-term purchase and sales contracts in addition to derivatives such as forward contracts, futures contracts, options, and swaps to manage these risks. We attempt to manage our risk associated with these activities through enforcement of established risk limits and risk management procedures. We cannot ensure that these strategies will be successful in managing our pricing risk or that they will not result in net liabilities because of future volatility in these markets.
Although we routinely enter into contracts to hedge our exposure to the risks of demand and changes in commodity prices, we do not hedg e the entire exposure of our operations from commodity price volatility. Furthermore, our ability to hedge our exposure to commodity price volatility depends on liquid commodity
markets. To the extent that commodity markets are illiquid, we may not be able to execute our risk management strategies, which could result in greater unhedged positions than we would prefer at a given time. To the extent that unhedged positions exist, fluctuating commodity prices can adversely affect our results of operations, financial po sition, and liquidity. Our facilities are considered critical energy infrastructure and may therefore be targets of acts of terrorism. Like other electric and natural gas utilities and other merchant electric generators, our energy centers, fuel storage facilities, and transmission and distribution facilities may be targets of terrorist activities, including cybersecurity attacks, that could result in disruption of our ability to produce or distribute some portion of our energy products. Any such disruption could result in a significant decrease in revenues or significant additional costs for repair, which could have a material adverse effect on our results of operations, financ ial position, and liquidity. Our businesses are dependent on our ability to access the capital markets successfully. We may not have access to sufficient capital in the amounts and at the times needed. We use short-term and long-term debt as a significant source of liquidity and funding for capital requirements not satisfied by our operating cash flow, including requirements related to future environmental compliance
and capital expenditures required by the IEIMA. As a result of rising costs and increased capital and operations and maintenance Table of ContentsFor information on our principal properties, see the generating facilities table below. See also Liquidity and Capital Resources and Regulatory Matters in Management's Discussion and Analysis of Financial Condition and Results of Operations under Part II, Item 7, of this report for any discussion of planned additions, replacements or transfers. See also Note 5 - Long-term Debt and Equity Financings, and Note 15 - Commitments and Contingencies under Part II, Item 8, of this report. 24 ITEM 2.PROPERTIES. expenditures, coupled with regulatory lag, we expect to continue to rely on short-term and long-term debt financing. The inability to raise debt or equity capital on favorable terms, or at all, could negatively affect our ability to maintain and to expand our businesses. After assessing our current operating performance, liquidity, and credit ratings, we believe that Ameren and its rate-regulated businesses will continue to have access to the capital markets. However, events beyond our control, such as a recession or extreme volatility in global debt or equity capital and credit markets, may create uncertainty that could increase our cost of capital or impair or eliminate our ability to access the debt, equity or credit markets, including our ability to draw on bank credit facilities. Based on projections as of December 31, 2011, of Genco's operating results and cash flows, we expect that, by the end of the first quarter of 2013, Genco's interest coverage ratio will be less than the minimum ratio required under its indenture for the company to borrow additional funds from external, third-party sources. An inability to raise debt could adversely impact Genco's liquidity. Any adverse change in the Ameren Companies' credit ratings may reduce access to capital and trigger
additional collateral postings and prepayments. Such changes may also increase th e cost of borrowing and fuel, power and natural gas s upply, among other things, which could have a material adverse effect on our results of operations, financial position, and liquidity. Certain of the Ameren Companies rely, in part, on Ameren for access to capital. Circumstances that limit Ameren's access to capital, including those relating to its other subsidiaries, could impair its ability to provide those Ameren Companies with needed capital. In addition, borrowings directly from Ameren and from the utility and non-state-regulated subsidiary money pools are subject to Ameren's control, and any borrowings are dependent on consideration by Ameren of the facts and circumstances existing at the time of any borrowing request. Ameren's holding company structure could limit its ability to pay common stock dividends and to service its debt obligations. Ameren is a holding company; therefore, its primary assets are the common stock of its subsidiaries. As a result, Ameren's ability to pay dividends on its common stock depends on the earnings of its subsidiaries and the ability of its subsidiaries to pay dividends or otherwise transfer funds to Ameren. Similarly, Ameren's ability to service its debt obligations is also dependent upon the earnings of operating subsidiaries and the distribution of those earnings and other payments, including payments of principal and interest under intercompany indebtedness. The payment of dividends to Ameren by its
subsidiaries in turn depends on their results of operations and cash flows and other items affecting retained earnings. Ameren's subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any dividends or make any other distributions (except for payments required pursuant to the terms of intercompany borrowing arrangements) to Ameren. Certain of the Ameren Companies' financing agreements and articles of incorporation, in addition to certain statutory and regulatory requirements, may impose restrictions on the ability of such Ameren Companies to transfer funds to Ameren in the form of cash dividends, loans or advances. Failure to retain and attract key officers and other skilled professional and technical employees could have an adverse effect on our operations. Our businesses depend upon our ability to employ and retain key officers and other skilled professional and technical employees. A significant portion of our workforce is nearing retirement, including many employees with specialized skills such as maintaining and servicing our electric and nat ural gas infrastructure and operating our energy centers. Any inability to retain and recruit qualified employees could adversely affect our results of operations. None. ITEM 1B.UNRESOLVED STAFF COMMENTS.

Table of Contents ITEM 7.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. OVERVIEW Ameren Executive Summary
Operations During 2011, Ameren remained committed to providing its customers with safe, reliable, environmentally responsible and reasonably-priced energy while at the same time enhancing value for our shareholders. Ameren Missour i and Ameren Illinois seek to earn competitive returns on their investments by improving their regulatory frameworks and seeking rate increases as needed. Ameren's Merchant Generation business seeks to protect and enhance shareholder value by minimizing operating and capital spending during the current period of low power prices while advocating for regulatory policies and power market improvements that will lead to improved economics. Ameren is committed to
allocating capital to projects that have an opportunity to earn a competitive return and to aligning its spending with regulatory outcomes and economic conditions. There were several developm ents during 2011 and early 2012 that have the potential to improve the level or predictability of earned returns at Ameren Missouri and Ameren Illinois. In January 2012, Ameren Illinois elected to participate in the IEIMA's performance-based formula ratemaking process for electric delivery service. As a result, Ameren Illinois' electric delivery service earnings in 2012 and beyond are expected to reflect performance-based formula ratemaking, which will enable additional infrastructure investment and the creation of jobs. The improved infrastructure will enhance reliability and provide customers with the energy usage options made possible by smart meters. Also in January 2012, the ICC approved an increase in annual Ameren Illinois' revenues for natural gas delivery service. In 2011, Ameren Missouri received rate increases for its electric and natural gas businesses. In February 2012, Ameren Missouri filed an electric rate case with the MoPSC seeking to recover its operating and capital costs and to earn a fair return on investments made to serve its customers. In addition to that pending electric rate case, in January 2012, Ameren Missouri filed its first request with the MoPSC for approval of new and expanded energy efficiency programs along with a cost-recovery mechanism under the MEEIA. The MEEIA was designed to enable utilities to pursue cost effective energy efficiency programs by aligning the utility's financial incentives with those of its customers. Also, FERC is expected to issue an order on MISO's proposal to establish a capacity market within the RTO.
The MISO proposal calls for the first annual capacity auction to be held in April 2013 for the June 2013 to May 2014 planning year. Ameren supports the MISO proposal as well as MISO's efforts to increase the amount of capacity that can be shared between MISO and PJM.
Ameren will continue to advocate for a multi-year capacity construct to improve the functioning of power markets.
The creation of a MISO capacity market would more accurately reflect the value of capacity, improve efficiency The Merchant Generation segment expects its cash flows from operating activities to exceed capital
expenditures in 2012 reflecting the benefit of its forward power sales and hedging programs as well as actions taken to reduce spending. In early 2012, there has been a sharp decline in forward power prices. The decline in power prices is believed to be caused by factors such as declining natural gas prices and the stay of the CSAPR. It is unclear when legal and regu latory uncertainties related to CSAPR will be resolved and when natural gas prices will recover. As a result of the declining price of power, Merchant Generation and Genco have revised their capital spending plans. Genco is decelerating construction of its Newton energy center scrubber project, postponing installation until such time as the incremental investment necessary for completion is justified by visible market conditions. In addition, AERG has removed from its five-year capital expenditure plans the previously
planned precipitator upgrades at its E.D. Edwards energy center. Merchant Generation believes these actions are the best path to achieving appropriate returns on incremental environmental investments during this period of low power prices. These Merchant Generation actions will reduce capital needs by approximately $270 million from 2012 through 2014 compared to prior plans. Genco will decelerate the Newton scrubber project in a manner that preserves the value of the work commissioned to date. Genco has reduced its expected 2012 capital expenditures for the Newton scrubber project to approximately $150 million. After 2012, Genco will perform minimal amounts of ongoing construction activities such that when the economics merit completing the Newton scrubber project, the project can be completed in an orderly and cost-effective manner. Ameren plans to significantly grow its investment in electric transmission assets, which are regulated by FERC. Ameren expects to invest a total of approximately $1.7 billion in transmission projects over the five-year period ending in 2016. Of that total, Ameren Illinois expects to invest $900 million in transmission projects that are focused on local load growth and reliability needs. In December 2011, MISO approved the Illinois Rivers, Spoon River, and Mark Twain projects. ATX and
ATXI's total investment in these three MISO-approved projects is expected to be more than $1.2 billion through 2019, with potential investment of approximately $750 million from 2012 to 2016. In 2012, ATXI is moving forward with the line routing and siting process for the Illinois Rivers project. Earnings Ameren reported net income of $519 million, or $2.15 per share, for 2011 compared with net income of $139 million, or 58 cents per share, in 2010. The main factor contributing to the increase in earnings in 2011 compared with 2010 was a reduction in goodwill, impairment and other charges of $464 million, or $1.87 per share. The 2011 charges were the result of the 32 and reliability, and benefit customers over the long-term. MoPSC's July 2011 disallowance of costs of enhancements related to the rebuilding of Ameren Missouri's Taum Sauk energy Table of Contentscenter in excess of amounts recovered from property insurance, as well as new environmental rules, the primary impact of which was Genco's closure of the Meredosia and Hutsonville energy centers. Ameren's
earnings also increased in 20 11, compared with 2010, because of higher electric utility rates for Ameren Missouri and Ameren Illinois and lower interest expense. Offsetting factors included reduced electric margins in the Merchant Generation segment due to lower realized power prices and higher fuel and transportation-related expenses; lower electric sales to native load utility customers due, in part, to summer temperatures that while warmer than normal, were below those of a very hot 2010; unrealized net losses on MTM activity related to nonqualifying power hedges and fuel-related contracts; and higher major storm
repair expenses. Additionally, Ameren recorded a charge to earnings associated with the voluntary separation offers to eligible Ameren Missouri and Ameren Services employees during the fourth quarter of 2011.
LiquidityCash flows from operations of $1.9 billion were used to pay dividends to common stockholders of $375 million
and to fund capital expenditures of $1.0 billion. At December 31, 2011, Ameren, on a consolidated basis, had available liquidity, in the form of cash on hand and amounts available under its existing credit facilities, of approximately $2.2 billion, which was a $300 million increase in the amount of available liquidity at December 31, 2010.
Capital Spending From 2012 through 2016, Ameren's cumulative capital spending is projected to range between $6.5 billion and $8.3 billion. Much of this spending is at Ameren's rate-regulated utilities, including a total of approximately
$750 million at ATX and ATXI, in the aggregate, to invest in their electric transmission assets. The Merchant Generation segment's capital spending is expected to be up to $450 million, primarily for environmental compliance, from 2012 through 2016. The decision to make pollution control equipment investments in Ameren's Merchant Generation segment depends on
whether the expected future market price for power reflects the increased cost of environmental compliance. General Ameren, headquartered in St. Louis, Missouri, is a public utility holding company under PUHCA 2005, administered by FERC. Ameren's primary assets are the common stock of its subsidiaries. Ameren's subsidiaries
are separate, independent legal entities with separate businesses, assets, and liabilities. These subsidiaries operate, as the case may be, rate-regulated electric generation, transmission, and distribution businesses, rate-regulated natural gas transmission and distribution
businesses, and merchant elec tric generation businesses in Missouri and Illinois. Dividends on Ameren's common stock and the payment of other expenses by Ameren depend on distributions made to it by its subsidiaries. Ameren's principal subsidiaries are listed below. See Note 1 - Summary of Significant Accounting Policies under Part II, Item 8, of this report for a detailed description of our principal subsidiaries. On October 1, 2010, Ameren, CIPS, CILCO, IP, AERG and AER completed a two-step corporate internal reorganization. The first step of the reorganization was the Ameren Illinois Merger. Upon consummation of the Ameren Illinois Merger, the separate legal existence of CILCO and IP ended. The second step of the reorganization involved the distribution of AERG stock from Ameren Illinois to Ameren and the subsequent contribution by Ameren of the AERG stock to AER. The Ameren Illinois Merger and the distribution of AERG stock were accounted for as transactions between entities under common control. In accordance with authoritative
accounting guidance, assets and liabilities transferred between entities under common control were accounted for at the historical cost basis of the common parent, Ameren, as if the transfer had occurred at the beginning of the earliest reporting period presented. Ameren's historical cost basis in Ameren Illinois included purchase accounting adjustments related to Ameren's acquisition of CILCORP in 2003. Ameren Illinois accounted for the AERG distribution as a spinoff. Ameren Illinois transferred AERG to Ameren based on AERG's carrying value.
Ameren Illinois has segregated AERG's operating results and cash flows and presented them separately as discontinued operations in its consolidated statement of income and consolidated statement of cash flows, respectively, for all periods presented prior to October 1, 2010, in this report. For Ameren's financial statements, AERG's results of operations remain classified as continuing operations. See Note 16 - Corporate Reorganization and Discontinued Operations under Part II, Item 8, for additional information. Effective January 1, 2010, as part of an internal reorganization, AER transferred its 80% stock ownership interest in EEI to Genco through a capital contribution. The transfer of EEI to Genco was accounted for as a transaction between entities under common control, whereby Genco accounted for the transfer at the historical carrying value of the parent (Ameren) as if the transfer had occurred at the beginning of the earliest reporting period presented. Ameren's historical cost basis in EEI included purchase Ameren Missouri operates a rate-regulated electric generation, transmission and distribution business, and a rate-regulated natu ral gas transmission and distribution business in Missouri. Ameren Illinois operates a rate-regulated electric and natural gas transmission a nd distribution business in Illinois.AER consists of non-rate-regulated operations, including Genco, AERG, Marketing Company and Medina Valley. The Medina Valley energy center was sold in February 2012. Genco operates a merchant electric generation business in Illinois and holds an 80% ownership interest in EEI.
Table of Contentsaccounting adjustments relating to Ameren's acquisition of an additional 20% ownership interest in EEI in 2004.
This transfer required Genco's prior-period financial statements to be retrospectively combined for all periods presented. Consequently, Genco's prior-period consolidated financial statements reflect EEI as if it had been a subsidiary of Genco. Ameren and Genco consolidate EEI for financial reporting purposes.
The financial statements of Ameren are prepared on a consolidated basis and therefore include the accounts
of its majority-owned subsidiaries. All significant intercompany transactions have been eliminated. All tabular dollar amounts are in millions, unless otherwise
indicated.In addition to presenting results of operations and earnings amounts in total, we present certain information in cents per share. These amounts reflect factors that directly affect Ameren's earnings. We believe this per share information helps readers to understand the impact of these factors on Ameren's earnings per share. All references in this report to earnings per share are based on average diluted common shares outstanding. RESULTS OF OPERATIONS Earnings Summary Our results of operations and financial position are affected by many factors. Weather, economic conditions, and the actions of key customers or competitors can significantly affect the demand for our services. Our results are also affected by seasonal fluctuations: winter heating and summer cooling demands. The vast majority of Ameren's revenues are subject to state or federal regulation. This regulation has a material impact on the price we charge for our services. Merchant Generation sales are also subject to market conditions for power. We
principally use coal, nuclear f uel, natural gas, and oil for fuel in our operations. The prices for these commodities can fluctuate significantly due to the global economic and political environment, weather, supply and demand, and many other factors. We have natural gas cost recovery mechanisms for our Illinois and Missouri natural gas delivery service businesses, a purchased power cost recovery mechanism for our Illinois electric delivery service business, and a FAC for our Missouri electric utility business. Fluctuations in interest rates and conditions in the capital and credit markets affect our cost of borrowing and our pension and postretirement benefits costs. We employ various risk management strategies to reduce our exposure to commodity risk and other risks inherent in our business. The reliability of our energy centers and transmission and distribution systems and
the level of purchased power costs, operations and maintenance costs, and capital investment are key factors that we seek to control to optimize our results of operations, financial po sition, and liquidity. Net income attributable to Ameren Corporation was $519 million, or $2.15 per share, for 2011, $139 million, or
$0.58 per share, for 2010, and $612 million, or $2.78 per share, for 2009. 2011 versus 2010 Net income attributable to Ameren Corporation increased $380 million, and earnings per share increased
$1.57 in 2011 compared with 2010. The Merchant Generation segment reported net income attributable to Ameren Corporation of $45 million in 2011, compared with a $409 million net loss in 2010. Net income attributable to Ameren Corporation decreased in the Ameren Missouri and Ameren Illinois Regulated segments by $77 million and $15 million, respectively, in 2011 compared with 2010. Compared with 2010 earnings per share, 2011 earnings were favorably affected by: reduced goodwill, impairment and other charges in the Merchant Generation segment offset, in part, by a charge to earnings related to the MoPSC's July 2011 disallowance of costs of en hancements relating to the rebuilding of the Taum Sauk energy center in excess of amounts recovered from property insurance ($1.87 per share);higher Ameren Missouri electric rates pursuant to orders issued by the MoPSC, which became effective in June 2010 and in July 2011, as well as higher Ameren Missouri natural gas rates pursuant to a
MoPSC order, which became effective in late February 2011. The impact of the Ameren Missouri electric rate increases on earnings was reduced by the adoption of life span depreciation methodology, recognition in 2010 of regulatory assets for previously-expensed costs in the prior-year period, and increased regulatory asset amortization as directed by the rate orders (17 cents per share). These amounts exclude the unfavorable impact of the charge to
earnings related to the MoPSC's disallowance of Taum Sauk rebuildin g costs discussed above; lower interest expense, primarily due to the maturity and repayment of $200 million of Genco's senior secured notes in November 2010, the redemption of
$66 million of Ameren Missouri's subordinated deferrable interest debentures in September 2010, Ameren Illinois' redemptions of $150 million of senior secured notes and $40 million of first mortgage bonds in June 2011 and September 2010, respectively, and a reduction in borrowings under credit facility a greements (12 cents per share
);higher Ameren Illinois electric rates pursuant to orders issued b y the ICC in 2010 (6 cents per share
);the absence in 2011 of a charge for the impact on deferred taxes from changes in federal health care laws (6 cents per share
);the absence in 2011 of charges recorded in 2010 for cancelled or unrecoverable projects at Ameren Missouri (6 cents per share); a reduction in operations and maintenance expense related to plant maintenance, primarily at Ameren Missouri, as fewer costs were incurred for major
outages at coal-fired energy centers as the scope of the outages in 2011 was not as extensive as the scope of the outages conducted in 2010 (5 cents per
share); and Table of ContentsCompared with 2010 earnings per share, 2011 earnings were unfavorably affected by: The cents per share information presented above is based on average shares outstanding in 2010. 2010 versus 2009 Net income attributable to Ameren Corporation decreased$473 million, and its earnings per share reduction in expense as a result of disciplined cost management efforts to align spending with regulatory outcomes and economic conditions. lower electric margins in the Merchant Generation segment, largely due to lower realized revenue per megawatthour sold and higher fuel and related transportation costs (21 cents per share). This amount

Compared with 2009 earnings per share, 2010 earnings were negatively affected by: Compared with 2009 earnings per share, 2010 earnings were favorably affected by: the 2010 impairment of goodwill, intangible assets, and long-lived assets within the Merchant Generation segment due to the sustained decline in market prices for electricity, industry market multiples becoming observable at lower levels than previously estimated, and potentially more stringent environmental regulations ($2.19 per share); lower realized electric margins in the Merchant Generation segment largely due to lower realized revenue per megawatthour sold and higher fuel and
related transportation costs (79 cents per share). This amount excludes the unfavorable impacts of net unrealized MTM activity on nonqualifying power hedges discussed below; higher dilution (23 cents per share) caused by an increase in the average number of common shares outstanding, largely because of a September 2009 common stock issuance, the proceeds of which were used to make investments in Ameren's rate-regulated utilities. The impact of dilution was offset by higher earned returns on investments at Ameren's rate-

Table of Contents MarginsThe following table presents the favorable (unfavorable) variations in the registrants' electric and natural gas margins from the previous year. Electric margins are defined as electric revenues less fuel and purchased power costs. Natural gas margins are defined as gas revenues less gas purchased for resale. The table covers the years ended December 31, 2011, 2010, and 2009. We consider electric and natural gas margins useful measures to analyze the change in profitability of our electric and natural gas operations between periods. We have included the analysis below as a complement to the financial information we provide in accordance with GAAP. However, these margins may not be a presentation defined under GAAP, and may not be comparable to other companies' presentations or more useful than the GAAP information we provide elsewhere in this report. 37 2011 versus 2010 AmerenMissouriAmeren Illinois RegulatedSegmentGencoOtherAmerenElectric revenue change: Effect of weather (estimate)$(29)$(7)$- $- $(36)Regulated rates: Hi gher base rates172 29 - -201 Recovery of FAC unde r-recovery89 - - -89 Of f-s y stem revenues53 - - -53 FAC disallowance(17)- - -(17)Transmission services 1 (4) - 3-Illinois pass-through power supply costs-(112) - (1)(113)Energy efficiency programs and environmental remediation cost riders -6Bad debt ride r-(17) - -(17)Rate-regulated sales (excluding the impact of abnormal weather)(37)(15) - -(52)Wholesale revenues (43)- - -(43)Merchant Generation sales price changes, including hedge effect-- (58) (3)(61)Net unrealized MTM losses (2)-(4)(12)(18)Non-rate-regulated sales and othe r5(1) 2 11 17 Total electric revenue change$ 192 $(121) $(60) $(2) $9 Fuel and purchased power change: Fuel: Merchant Generation production volume and othe r$- $- $(2) $14 $12 Fuel and transportation costs included in base rates(84)- - -(84)Recovery of FAC unde r-recovery(89)- - -(89)Net unrealized MTM losses-- (6) (2)(8)

(a)(b)(c)(c)(b)2011 versus 2010 A meren Ameren's electric margins decreased by $95 million, or 2%, in 2011 compared with 2010. The following items had an unfavorable impact on Ameren's electric margins: Lower sales prices, including hedge effects, at the Merchant Generation segment due to reductions in higher-margin sales resulting from the expiration of the 2006 auction power supply agreements on May 31, 2010, and lower market prices resulting in fewer opportunities for economic power sales, which decreased margins by $61 million. Excluding the estimated impact of abnormal weather, rate-regulated retail sales volumes declined 1%, attributable to continued economic pressure, energy efficiency measures and customer conservation efforts, which decreased revenues by $52 million. Lower wholesale sales at Ameren Missouri due to a reduction in customers, the expiration of favorably priced contracts and the inclusion of revenues from the remaining contracts as an offset to fuel costs in the FAC beginning July 31, 2011, which decreased revenues b y $43 million. Summer weather conditions in 2011 were not as hot as a very hot 2010, as evidenced by a 4% decrease in Table of ContentsThe following items had a favorable impact on Ameren's electric margins in 2011 compared with 2010: cooling degree-days, which decreased revenues by $36 million. However, weather conditions in Ameren's service territory in 2011 were still warmer than normal
as evidenced b y 19% more coolin g de gree-da y s. Net unrealized MTM losses principally at the Merchant Generation segment (primarily at Marketing Company), related to nonqu alifying power hedges and fuel-related contracts, which decreased margins by
$26 million. Decreased utilization of Merchant Generation's energy centers, primarily due to planned and unplanned outages and lower market prices resulting in fewer opportunities for economic power sales.
Decreased utilization resulted in a $23 million decline in non-rate-regulated sales. This decline was mitigated by a $12 million decrease in Merchant Generation production volume and other costs. A $17 million reduction in revenues, recorded in the second quarter of 2011, at Ameren Missouri resulting from the MoPSC's order with respect to its FAC disallowance for the period from March 1, 2009, to September 30, 2009. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, for further information regarding the FAC prudence review. Decreased recovery of prior years' bad debt expense at Ameren Illinois, through the Illinois bad debt rider, which became effective in March 2010, which decreased margins by $17 million. See Operations and Maintenance in this section for additional information on a related offsetting decrease in bad debt expense. 6% higher fuel prices in th e Merchant Generation segment, primarily due to higher commodity and transportation costs associated with new supply contracts, which decreased margins by $17 million. Higher electric base rates at Ameren Missouri, effective June 2010 and July 2011, which increased revenues by $172 million, offset by an increase in net base fuel expense ($31 million), which was a result of higher net base fuel cost rates approved in the 2010
and 2011 MoPSC rate orders and due to higher fuel and transportation costs.
Net base fuel expense is the sum of fuel and transportation costs included in base rates (-$84 million) and off-system revenues (+$53 million) in the above table. See below for additional
details re gardin g the FAC. Higher electric delivery service rates at Ameren Illinois, effective in early May and November 2010, which increased margins by $20 million, and higher wholesale revenues due to an increase in electric delivery service rates effective April 2011, which increased margins by $9 million. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, for further information regarding the 2011 wholesale distribution rate case. Increased recovery of energy efficiency program costs and environmental remediation costs through Illinois rate-adjustment mechanisms at Ameren Illinois, which Ameren's revenues associated with Illinois pass-through power supply costs decreased $113 million
because of lower power prices on sales primarily to nonaffiliated parties. These revenues were offset by a
corresponding net decrease in purchased power. Ameren Missouri has a FAC cost recovery mechanism that allows Ameren Missouri to recover, through customer rates, 95% of changes in fuel and purchased power costs, net of off-system revenues, including MISO costs and revenues, greater or less than the amount set in base rates, without a traditional rate proceeding. Ameren Missouri accrued, as a regulatory asset, fuel and purchased power costs that were greater than the amount set in base rates (FAC under-recovery).
Net recovery of fuel costs under the FAC through customer rates increased by $89 million in 2011, as compared with 2010, with corresponding offsets to fuel expense to reduce the previously recognized FAC regulatory asset. See below for explanations of electric and natural gas margin variances for the Ameren Missouri segment. Ameren's natural gas margins decreased by $17 million, or 4%, in 2011 compared with 2010. The following items had an unfavorable impact on Ameren's natural gas margins: Ameren's natural gas margins were favorably affected by $8 million in 2011 compared with 2010 due to higher natural gas rates effective February 2011 at Ameren Missouri and effective in May and November 2010 at
Ameren Illinois.
A meren Missouri Ameren Missouri has a FAC cost recovery mechanism, which is outlined in the Ameren margin section above. Ameren Missouri's electric margins increased by $19 million, or 1%, in 2011 compared with 2010. Ameren Missouri's electric margins were favorably affected by information on a related offsetting increase in energy efficienc y and environmental remediation costs. Decreased recovery of prior years' bad debt expense through the Illinois bad debt rider at Ameren Illinois, which became effective March 2010, decreased margins by $14 million. See Other Operations and Maintenance Expenses in this section for additional information on a related offsetting decrease in bad debt expense. Unfavorable winter weather conditions, as evidenced by a 6% decrease in heating degree-days, which decreased revenues by $6 million. Compared to normal, Ameren experienced 3% fewer heating
de g ree-da y s in 2011. 4% lower native load sales volumes, excluding the estimated impact of abnormal weather, largely in the commercial and industrial sectors, attributable to
continued economic pressure decreased margins by $4 million.
39 increased margins by $6 million. See Other Operations and Maintenance Expenses in this section for Table of Contents higher electric base rates, effective in June 2010 and July 2011 ($172 million), offset by increased net base fuel expense ($31 million), which was a result of higher net base fuel cost rates approved in the 2010 and 2011 MoPSC rate orders and due to higher fuel and transportation costs. Net base fuel expense is the sum of
fuel and transportation costs included in base rates (-$84 million) and off-system revenues (+$53 million) in the above table. The following items had an unfavorable impact on Ameren Missouri's electric margins in 2011 compared with 2010: Ameren Missouri's natural gas margins increased by $4 million, or 5%, in 2011 compared with 2010. Ameren Missouri's natural gas margins were favorably affected by higher natural gas rates, effective February 2011, which increased margins by $5 million.
Ameren Illinois Regulated Segment Ameren Illinois has a cost recovery mechanism for power purchased on behalf of its customers. These pass-through power costs do not affect margins; however, the electric revenues and offsetting purchased power costs may fluctuate, primarily because of customer switching to alternative power providers and usage. Ameren Illinois does not generate earnings based on the resale of power, but rather on the delivery of energy. Ameren Illinois' electric margins decreased by $9 million, or 1%, in 2011 compared with 2010. The following items had an unfavorable impact on electric margins:Lower wholesale sales due to a reduction in customers, the expiration of favorably priced contracts, and the inclusion of revenues from the remaining contracts as an offset to fuel costs in the FAC beginning July 31, 2011, which decreased revenues b y $43 million. Excluding the estimated impact of abnormal weather, rate-regulated retail sales volumes declined by 1%,
attributable to continued economic pressure, energy efficiency measures, and customer conservation efforts, which decreased revenues by $37 million. Summer weather conditions in 2011 were not as hot as a very hot 2010, as evidenced by a 3% decrease in cooling degree-days, which decreased revenues by $29 million. However, weather conditions in Ameren Missouri's service territory in 2011 were still warmer than normal as evidenced by 20% more cooling de g ree-da ys. A $17 million reduction in revenues, recorded in the second quarter of 2011, resulting from the MoPSC's order with respect to its FAC disallowance for the period from March 1, 2009 to September 30, 2009. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, for further information regarding the FAC
prudence review. Decreased recovery of prior years' bad debt expense under the Illinois bad debt rider, which became effective in March 20 10, which decreased mar g ins b yThe following items had a favorable impact on Ameren Illinois' electric margins in 2011 compared with 2010: Ameren Illinois' natural gas margins decreased by $21 million, or 6%, in 2011 compared with 2010. The following items had an unfavorable impact on Ameren Illinois' natural gas margins: Ameren Illinois' gas margins were favorably affected by $3 million due to higher natural gas rates effective in May and November 2010. Merchant Generation Merchant Generation's electric margins decreased by $112 million, or 14%, in 2011 compared with 2010. See below for explanations of electric margin variances for the $17 million. See Operations and Maintenance in this section for additional information on a related offsettin g decrease in bad debt expense. Continued economic pressure, energy efficiency measures, and customer conservation efforts, which decreased revenues by $15 million. Summer weather conditions in 2011 were not as hot as a very hot 2010, as evidenced by a 5% decrease in cooling degree-days, which decreased revenues by $7 million. However, weather conditions in Ameren Illinois' service territory in 2011 were still warmer than normal as evidenced by 18% more co oling degree-da y s.Higher electric delivery service rates, effective in early May and November 2010, increased margins by
$20 million and higher wholesale revenues due to an increase in electric delivery service rates effective April 2011, which increased margins by $9 million.
See Note 2 - Rate and Regulatory Matters under Part II, Item 8, for further information regarding the 2011 wholesale distribution rate case. Increased recovery of energy efficiency program costs and environmental remediation costs through Illinois rate-adjustment mechanisms, which increased margins by $6 million. See Operations and Maintenance in this section for information on a related offsetting increase in energy efficiency and
environmental remediation costs. Decreased recovery of prior years' bad debt expense under the Illinois bad debt rider, which became effective March 2010, which decreased margins by $14 million. See Other Operations and Maintenance Expenses in this section for additional information on a related offsetting decrease in bad debt expense. Unfavorable winter weather conditions, as evidenced by a 5% decrease in heating degree-days, decreased revenues by $5 million. However, compared to normal, Ameren Illinois experienced in 2011 a 2%
decrease in heatin g de g ree-da y s. Native load sales volumes declined by 4%, excluding the estimated impact of abnormal weather, largely in the commercial and industrial sectors, attributable to continued economic pressure, which decreased revenues by $4 million.
40 Merchant Generation segment.
Table of ContentsGenco Genco's electric margins decreased by $73 million, or 13%, in 2011 compared with 2010. The following items had an unfavorable impact on electric margins: Genco's energy center utilization in 2011 was comparable with 2010. Genco's production volume increased electric revenues by $2 million, which was offset by a $2 million increase in Merchant Generation production volume and other costs. Genco's average capacity factor remained unchanged at 71% in 2011 and 2010, but Genco's equivalent availability factor decreased to 86% in 2011, compared with 88% in 2010. Other Merchant Generation Electric margins from Ameren's other Merchant Generation operations, primarily AERG and Marketing Company, decreased by $39 million, or 16%, in 2011 compared with 2010. The following items had an unfavorable impact on electric margins: Lower revenues allocated to Genco under its power supply agreement (Genco PSA) with Marketing Company. There was a sm aller pool of money to allocate because of reductions in higher-margin sales, after the expiration of long-term contracts and because of lower market prices. However, in accordance with the Genco PSA, Genco was allocated a higher percentage of revenues from the pool because of higher reimbursable expenses and greater levels of generation relative to AERG. Genco also experienced lower market prices associated with EEI's power supply agreement with Marketing Company (EEI PSA). The combined impact of lower market prices under both power supply agreements resulted in an unfavorable price variance, which reduced revenues by $58 million. The decrease in revenues was mitigated by a favorable settlement of a contract dispute with a large customer in the second quarter of 2011. 5% higher fuel prices, primarily due to higher commodity and transportation costs associated with escalations in existing transportation agreements and new commodity supply agreements, which decreased
mar g ins b y $11 million. Net unrealized MTM activity on fuel-related transactions, primarily associated with financial instruments that were acquired to mitigate the risk of
rising diesel fuel price adjustments embedded in coal transportation contracts, and on nonqualifying power hedges, which decreased margins by $10 million. Decreased energy center utilization at AERG, primarily due to planned and unplanned outages and lower market prices resulting in fewer opportunities for economic power sales. AERG's lower production volume decreased electric revenues by $25 million, mitigated by a $14 million decline in Merchant Generation production volume and other costs.
AERG's average capacity factor decreased to 73% in 2011, compared with 75% in 2010, and AERG's equivalent availability factor decreased to 81% in 2010 versus 2009 A merenAmeren's electric margins increased by $202 million, or 5%, in 2010 compared with 2009. The following items had a favorable impact on Ameren's electric margins: Unfavorable net unrealized MTM activity, principally at Marketing Company, largely related to nonqualifying power hedges, which decreased margins by
$15 million. 6% higher fuel prices at AERG, primarily due to higher commodity and transportation costs associated with escalations in existing transportation agreements and new commodity supply agreements, decreased mar g ins b y $6 million. Lower revenues allocated to AERG under its power supply agreement (AERG PSA) with Marketing Company. There was a sm aller pool of money to allocate because of reductions in higher-margin sales, after the expiration of long-term contracts and
because of lower market pric es. In accordance with the AERG PSA, AERG was also allocated a lower percentage of revenues from the pool because of lower reimbursable expenses and lower levels of generation relative to Genco. The lower market prices resulted in an unfavorable price variance, which decreased revenues by $3 million. The decrease in revenues was mitigated by a favorable settlement of a contract dispute with a large customer in the second quarter of 2011. Favorable weather conditions, as evidenced by a 52%
increase in cooling degree-days, which increased revenues by $174 million. Weather conditions in Ameren's service territory were warmer than normal, as evidenced by 35% mo re cooling degree-days. Higher electric base rates at Ameren Missouri, effective March 2009 and June 2010, which increased revenues by $162 million, offset by net base fuel expense ($93 million), which was a result of higher net base fuel cost rates approved in the 2010 MoPSC rate order and due to higher fuel and transportation costs and reduced off-system revenues. Net base fuel expense is the sum of fuel and transportation costs included in base rates (+$9 million) and off-system revenues (-$102 million) in the above table. See below for additional details re gardin g the FAC. Increased Ameren Missouri sales to Noranda in 2010, as its smelter plant gradually returned to full capacity in March 2010, after a severe January 2009 storm significantly reduced the plant's capacity, which
increased revenues b y $54 million. Higher transmission revenues primarily associated with higher FERC-regulated transmission rates at Ameren Illinois, which increased margins by $49 million. Higher rates were due, in part, to a significant increase in transmission assets placed into service at Ameren Illinois during 2009, higher equity levels as a result of Ameren's capital contributions to Ameren Illinois in 2009 to improve its credit profile, and mild 2009 weather.

Table of ContentsThe following items had an unfavorable impact on Ameren's electric margins for 2010 compared with 2009: Ameren's Illinois pass-through power supply costs reflect lower power prices and the expiration of intercompany power supply agreements between Ameren Higher electric delivery service rates at Ameren Illinois, effective in early May and November 2010, as well as the adjustment of residential electric delivery rates effective in October 2009, to recover the full increase of IP's 2008 ICC rate order, which increased
margins by $41 million. Net unrealized MTM activity principally at the Merchant Generation segment (primarily at Marketing Company), related to nonqualifying power hedges, which increased mar g ins b y $49 million. Increased recovery of energy efficiency program costs and environmental remediation costs through Illinois rate-adjustment mechanisms at Ameren Illinois, which increased margins by $29 million. See Operations and Maintenance in this section for information on a related offsetting increase in energy efficiency program costs and environmental remediation costs. Excluding the impact of Ameren Missouri's increased sales to Noranda and the estimated impact of
abnormal weather, rate-regu lated retail sales volumes increased by 3%, largely because of improved economic conditions, which increased revenues by
$25 million. A reduction in the impact of the 2007 Illinois Electric Settlement Agreement, which increased margins by
$23 million. Increased recovery of prior years' bad debt expense through the Illinois bad debt rider at Ameren Illinois, which became effective March 2010, which increased margins by $14 million. See Operations and Maintenance in this section for additional information on a related offsettin g increase in bad debt expense. Reductions in higher-margin sales at the Merchant Generation segment after the expiration of the 2006 auction power supply agreements on May 31, 2010, and lower market prices that resulted in fewer
opportunities for economic power sales, which decreased mar g ins b y $243 million. 14% higher fuel prices in the Merchant Generation segment, primarily due to higher commodity and transportation costs associated with new supply contracts, which decreased mar g ins b y $71 million. In the first quarter of 2009, the reversal of previously unrealized losses related to regulatory assets resulted in the recognition of a $29 million net MTM gain on energy and fuel-related contracts at Ameren Missouri.
After the implementation of Ameren Missouri's FAC in March 2009, Ameren Missouri's net MTM gains or losses no longer affect electric margins. Net unrealized MTM activity at the Merchant Generation segment on fuel-related transactions, primarily associated with financial instruments acquired to mitigate the risk of rising diesel fuel price adjustments embedded in coal transportation contracts, reduced mar g ins b y $20 million. Illinois and Marketing Company. Ameren Illinois purchased power from Marketing Company from January 1, 2007, through May 31, 2010, under power supply agreements entered into following a 2006 Illinois power procurement auction. The purchases and sales
under these agreements were eliminated in consolidation for Ameren's financial statements. Subsequent to the expiration of these agreements in May 2010, Marketing Company's power sales and Ameren Illinois' power purchases have been made primarily with nonaffiliated parties. As a result, Amer en's consolidate d revenues increased by a net $220 million in 2010 compared with 2009. These revenues were offset by a corresponding
$220 million net increase in purchased power costs. Ameren Missouri has a FAC cost recovery mechanism that allows Ameren Missouri to recover, through customer rates, 95% of changes in fuel and purchased power costs, net of off-system revenues, including MISO costs and revenues, greater or less than the amount set in base rates, without a traditional rate proceeding. Ameren Missouri accrued, as a regulatory asset, fuel and purchased power costs that were greater than the amount set in base rates (FAC under-recovery). Net recovery of fuel costs under the FAC through customer rates increased by $60 million in 2010, as compared with 2009, with corresponding offsets to fuel expense to reduce the previously recognized FAC regulatory asset. See below fo r explanations of electric and natural gas margin variances for the Ameren Missouri segment. Ameren's natural gas margins increased by $2 million, or less than 1%, in 2010 compared with 2009.

See Operations and Maintenance in this section for additional information on a related offsettin g increase in bad debt expense. Favorable higher-margin customer mix that was mitigated by a 2% decrease in sales volumes, which increased margins by $2 million. Lower natural gas rates effective early May 2010 at Ameren Illinois, which reduced margins by $11 million.The absence of net unrealized MTM gains in 2010 of $6 million on natural gas swaps.
Table of ContentsAmeren Missouri's electric margins increased by $250 million, or 13%, in 2010 compared with 2009. The following items had a favorable impact on Ameren Missouri's electric margins: Ameren Missouri's electric margin was unfavorably affected by the reversal of previously unrealized losses to regulatory assets, which resulted in the recognition of a $29 million net MTM gain on energy and fuel-related contracts in the first quarter of 2009. This benefit did not recur in 2010. After the implementation of the FAC in March 2009, net MTM gains or losses no longer affect
electric margins. Ameren Missouri's natural gas margins increased by $2 million, or 3%, in 2010 compared with 2009 because of a 2% increase in sales volumes, largely due to improved economic conditions.
Ameren Illinois Regulated Segment Ameren Illinois has a cost recovery mechanism for power purchased on behalf of its customers. These pass-through power costs do not affect margins; however, the electric revenues and offsetting purchased power costs may fluctuate, primarily because of customer switching to Higher electric base rates, effective March 2009 and June 2010, which increased revenues by $162 million, offset by net base fuel expense ($93 million), which was a result of higher net base fuel cost rates approved in the 2010 MoPSC rate order and due to higher fuel and transportation costs and reduced off-system revenues. Net base fuel expense is the sum o f fuel and transportation co sts included in base rates (+$9 million) and off-system revenues (-$102 million) in the above table. Favorable weather conditions, as evidenced by a 44%
increase in cooling degree-days, which increased revenues by $134 million. Weather conditions in Ameren Missouri's service territory were warmer than normal as evidenced by 45% more cooling degree-da y s.Increased sales to Noranda in 2010 as its smelter plant gradually returned to full capacity in March 2010, after a severe January 2009 storm significantly reduced the plant's capacity, which increased electric revenues by $54 million. Taum Sauk energy center's return to service.
Although Taum Sauk was no t available to generate electricity for off-system revenues during 2009, Ameren Missouri had included $19 million in the calculation of the FAC as if Taum Sauk had generated off-system revenues. Upon Taum Sauk's return to service in April 2010, Ameren Missouri's margins increased. The adjustment factor was eliminated from
the FAC calculation, which increased margins by $12 million.Excluding the impact of increased sales to Noranda and the estimated impact of abnormal weather, rate-
regulated retail sales volumes increased by less than 1%, largely because of improved economic conditions, which increased revenues b y $9 million. Ameren Illinois' electric margins increased by $179 million, or 20%, in 2010 compared with 2009. The following items had a favorable impact on electric

Higher rates were due, in part, to an increase in transmission assets placed into service during 2009, higher equity levels resulting from Ameren's capital contributions to IP in 2009, and mild 2009 weather. Higher electric delivery service rates, effective in early May and November 2010, as well as the adjustment
of residential electric delivery rates effective October 1, 2009, at IP to recover the full increase of the 2008 ICC rate order, which increased margins by
$41 million. Favorable weather conditions, as evidenced by a 65%

The following items had an unfavorable impact on electric margins: The following items had a favorable impact on Genco's electric margins in 2010 compared with 2009: Other Merchant Generation Electric margins from Ameren's other Merchant Lower revenues allocated to Genco under its power supply agreement (Genco PSA) with Marketing Company. There was a sm aller pool of money to allocate because of reductions in higher-margin sales, after the expiration of older long-term contracts and because of lower market prices. The lower market prices associated with the Genco PSA were mitigated by higher market prices associated with EEI's power supply agreement with Marketing Company (EEI PSA). The net impact of lower market prices under both power supply agreements reduced electric revenues by $81 million. In accordance with the Genco PSA, Genco was also allocated a lower percentage of revenues from the pool because of lower reimbursable expenses and lower generation relative to AERG. 14% higher fuel prices, primarily due to higher commodity and transportation costs associated with new supply contracts, which decreased margins by
$51 million. Net unrealized MTM activity on fuel-related transactions primarily associated with financial instruments that were acquired to mitigate the risk of
rising diesel fuel price adjustments embedded in coal transportation contracts, which reduced margins by
$19 million. A reduction in the impact of the 2007 Illinois Electric Settlement Agreement, which increased margins by
$10 million. Increased energy center utilization, primarily due to more economic sales opportunities and a reduction in transmission constraints, which previously limited the period in which power could be sold. In addition, one
of Genco's coal-fired energy centers experienced a transformer fire in September 2009, which put two units out of service for a time in 2009. The higher production volume contributed to the $50 million increase in electric revenues, which was mitigated by higher Merchant Generation production volume and other costs of $38 million. Genco's baseload coal-fired energy centers' average capacity factor increased to 71% in 2010, compared with 67% in 2009, and Genco's equivalent availability factor increased to 88% in 2010, compared with 82% in 2009.

However, in accordance with the AERG PSA, AERG was allocated a greater percentage of revenues from the pool because of higher reimbursable expenses and higher generation relative to Genco. 19% higher fuel prices at AERG primarily due to higher commodity and transportation costs associated with new supply contracts, which decreased margins
$20 million. Net unrealized MTM activity at Marketing Company improved margins by $46 million, largely related to nonqualifying power hedges. A reduction in the impact of the 2007 Illinois Electric Settlement Agreement at AERG, which increased
mar g ins b y $4 million. Increased energy center utilization at AERG, primarily due to more opportunities for economic sales and a reduction in energy center outages. The higher production volume increased electric revenues by
$37 million, which was partially offset by higher
Merchant Generation pro duction volume and other costs of $9 million. AERG's baseload coal-fired energy centers' average capacity factor increased to 75% in 2010, compared with 69% in 2009, while AERG's equivalent availability factor increased to 85% in 2010, compared with 78% in 2009. Charges in 2010 of $22 million due to cancelled or unrecoverable projects at Ameren Missouri that did not recur in 2011. A decrease of $20 million in plant maintenance costs, primarily because the scope of the outages in 2011 were not as extensive as the scope of the outages performed in 2010.

The following items reduced other operations and maintenance expenses between years: Increased plant maintenanc e and labor costs of $39 million associated with a refueling and
maintenance outage at th e Callaway energy center and an increase of $16 million for other scheduled coal-fired plant outages, the installation of scrubbers at Ameren Missouri's Sioux energy center, and other maintenance work. There was no Callaway energy center refuelin g and maintenance outa g e in 2009. A $46 million increase in bad debt expense. The July 2009 capitalization and recovery of prior years' bad debt expense under the Ameren Illinois bad debt rate adjustment mechanism (net of a related donation for customer assistance programs) reduced bad debt expense in 2009. Additionally, bad debt expense increased in 2010, because of amortization of regulatory assets set up in conjunction with the Ameren Illinois bad debt rate adjustment mechanism
in 2009. Amortization expense associated with these regulatory assets was offset by increased revenues through collection from customers, with no overall impact on net income. Increased Ameren Illinois energy efficiency program costs and environmental remediation costs of $30 million. Energy efficiency program costs are allowed to be recovered from customers under the 2007 Illinois Electric Settlement Agreement; environmental remediation costs associated with MGPs are recoverable from customers through Ameren Illinois environmental adjustment rate riders.
Accordingly, these costs are offset by increased revenues, with no overall impact on net income. See Note 2 - Rate and Regulatory Matters and Note 15 - Commitments and Contingencies under Part II, Item 8, of this report for additional information. An unfavorable change of $7 million in unrealized net MTM adjustments between years, resulting from changes in the market value of investments used to support Ameren's deferred compensation plans. The absence in 2010 of major storms, such as those in 2009, which resulted in a $27 million reduction in
other operations and maintenance expenses. Severance costs of $17 million for employee separation programs recognized in 2009, as compared with $4 million in 2010. A May 2010 MoPSC electric rate order, which resulted in Ameren Missouri recording regulatory assets in 2010 related to employee severance costs, and storm costs incurred in 2009, which decreased expenses b y $11 million.

A $40 million increase in bad debt expense resulting from the July 2009 capitalization and recovery of prior years' bad debt expense under the Ameren Illinois bad debt rate adjustment mechanism (net of a related donation for customer assistance programs), which decreased bad debt expense in 2009, and the amortization in 2010 of re g ulator y assets set up in Table of Contents The following items reduced other operations and maintenance expenses between years: Merchant Generation Other operations and maintenance expenses decreased by $46 million in 2010 in the Merchant Generation segment, primarily because of variations at Genco, as discussed below. Additionally, other operations and maintenance expenses decreased at AERG, primarily because of lower labor costs due to staff reductions, and reduced severance costs due to employee separation programs that were implemented in 2009. Genco Other operations and maintenance expenses decreased by $35 million in 2010. Plant maintenance costs were lower by $16 million due to the retirement in 2009 of two generation units at Genco's Meredosia energy center and other reductions in required maintenance work. Additionally, other operations and maintenance costs were lower due to a $7 million reduction in employee benefit costs, due, in part, to reduced severance costs because of employee separation programs in 2009, a $5 million decline in labor costs resulting from staff reductions, and a property sale gain in 2010. Goodwill, Impairment and Other Charges The following table summarizes goodwill, impairment and other charges for the years ended December 31, 2011, 2010, and 2009: conjunction with the Ameren Illinois bad debt rate ad justment mechanism in 2009. Energy efficiency and environmental remediation costs increased b y $30 million, as discussed above. The absence of major storms in 2010, as compared with storm costs of $16 million in 2009.

A meren Corporation Goodwill, impairment and other charges decreasedby $464 million in 2011. Ameren Missouri and Genco recorded long-lived asset impairments and related charges in 2011, which are discussed individually below.
Additionally, Ameren and Genco recorded intangible asset impairment charges in 2011 relating to emission allowances of $2 million and $1 million, respectively.
Larger impairments were recorded in 2010, when Ameren recognized noncash, pretax impairment charges relating to goodwill, long-lived assets, and emission allowances within the Merchant Generation segment. The impairments recorded in 201 0 in the Merchant Generation segment were caused by a sustained decline in market prices for electricity, industry market multiples becoming observable at lower levels than previously estimated, and potentially more stringent environmental regulations being enacted. A meren Missouri In July 2011, the MoPSC issued an electric rate order that disallowed the recovery of costs of enhancements relating to the rebuilding of the Taum Sauk energy center in excess of the amounts recovered from property insurance. As a result, Ameren Missouri recorded a
pretax charge to earnings of $89 million in 2011. See Note 2 - Rate and Regulatory Matters to our financial statements under Part II, Item 8, of this report for additional information on the disallowance, including Ameren Missouri's appeal of the MoPSC's July 2011 electric rate order. Merchant Generation and Genco At the end of 2011, Genco ceased operations of its Meredosia and Hutsonville energy centers. The closure of these energy centers was primarily the result of the expected cost of complying with the CSAPR and the MATS. Genco determined that environmental compliance options for these four units were uneconomical. Another
factor driving the closure of these energy centers was a lack of a multiyear capacity market managed by MISO, without which Genco was not positioned to make the substantial investment for environmental controls that would be required to keep these units in service. As a result of these closures, Ameren and Genco each recorded a charge to earnings in 2011 of $34 million.
Larger impairments were recorded in 2010, when Ameren and Genco recognized noncash, pretax impairment
charges relating to goodwill, long-lived assets, and emission allowances. In 2009, Genco recorded asset impairment charges of $6 million as a result of the termination of a rail line extension project at a subsidiary of Genco and to adjust the carrying value of an office building owned by Genco to 47 its estimated fair value as of December 31, 2009. In addition, AERG recorded an asset impairment charge of
$1 million to adjust the carrying value of its Indian Trails generation facility's estimated fair value as of December 31, 2009.
Table of Contents48 Depreciation and Amortization 2011 versus 2010 A meren Corporation Ameren's depreciation and amortization expenses increased by $20 million in 2011 compared with 2010, because of items noted below. Partially mitigating these increases was an $8 million reduction in depreciation and amortization expenses at Ameren Services, primarily because of computer equipment becoming fully-depreciated during 2011.
Variations in depreciation an d amortization expenses in Ameren's business segments and for the Ameren Companies between 2011 and 2010 were as follows:
A meren Missouri Depreciation and amortization expenses increased by $26 million in 2011, primarily because of increased
depreciation and amortization ex pense resulting from the installation of scrubbers at the Sioux energy center and other capital additions. Additionally, an increase in Ameren Missouri's annual depreciation rates as a result of the 2010 MoPSC electric rate order resulted in higher
depreciation and amortization expenses.
Ameren Illinois Regulated Segment Depreciation and amortization expenses increased by $5 million in 2011, primarily because of capital additions. Merchant Generation and Genco Depreciation and amortization expenses were comparable between years in the Merchant Generation Segment and at Genco. 2010 versus 2009 A meren Corporation Ameren's depreciation and amortization expenses increased by $40 million in 2010 compared with 2009, because of items noted below.
Variations in depreciation an d amortization expenses in Ameren's business segments and for the Ameren Companies between 2010 and 2009 were as follows:
A meren Missouri Depreciation and amortization expenses increased by
$25 million in 2010, primarily because of capital additions and an increase in Ameren Missouri's annual depreciation rates due largely to the adoption of the life span depreciation methodology as a result of the 2010 MoPSC electric rate order.
Ameren Illinois Regulated Segment Depreciation and amortization expenses decreased by $6 million in 2010, primarily because of a reduction in amortization of regulatory assets. An ICC rate order in April 2010 extended the amortization period of the IP integration-related regulatory asset. See Note 2 - Rate and Regulatory Matters to our financial statements under Part lI, Item 8, of this report for additional information.Merchant Generation and Genco Depreciation and amortization expenses increased by $20 million in 2010 in the Merchant Generation segment, primarily because depreciation and amortization expenses increased by $17 million in 2010 at Genco, due to capital additions and increased depreciation rates resulting from depreciation studies performed in 2009. Taxes Other Than Income Taxes 2011 versus 2010 A meren Corporation Taxes other than income taxes increased by $8 million in 2011 compared with 2010, primarily because of items noted below at Ameren Missouri. Variations in taxes other than income taxes in Ameren's business segments and for the Ameren
Companies between 2011 and 2010 were as follows:
A meren Missouri Taxes other than income taxes increased by $11 million in 2011, primarily because of increased property taxes, due to higher state and local assessments and higher tax rates, and higher gross receipts taxes from increased revenues.
Ameren Illinois Regulated Segment Taxes other than income taxes were comparable between years. Increased property taxes in 2011, primarily due to higher tax rates, were mitigated by the absence of franchise taxes that were incurred in 2010 in association with the Ameren Illinois Merger. Merchant Generation and Genco Taxes other than income taxes were comparable between years in the Merchant Generation Segment and at Genco. 2010 versus 2009 A meren Corporation Taxes other than income taxes increased by $29 million in 2010 compared with 2009, because of items noted below.

A meren Missouri Taxes other than income taxes increased by $28 million in 2010, primarily because of higher gross receipts taxes as a result of increased sales, and because of increased property taxes due to higher assessed tax rates in Missouri.
Ameren Illinois Regulated Segment and Merchant Generation Taxes other than income taxes were comparable between years in the Ameren Illinois Regulated Segment, in the Merchant Generation segment, and at Genco. Other Income and Expenses 2011 versus 2010 A meren Corporation Miscellaneous income, net of expenses, decreased by $11 million in 2011 compared with 2010, primarily because of items noted below. Variations in miscellaneous income, net of expenses, in Ameren's business segments and for the Ameren Companies between 2011 and 2010 were as follows:
A meren Missouri Miscellaneous income, net of expenses, decreased by $19 million in 2011, primarily because of reduced allowance for equity funds used during construction. Allowance for equity funds used during construction was higher in 2010, primarily due to scrubbers being constructed at Ameren Missouri's Sioux energy center, which were placed in service in late 2010.
Ameren Illinois Regulated Segment Miscellaneous income, net of expenses, increased by $7 million in 2011, primarily because of reduced expenses associated with customer assistance programs. Merchant Generation and Genco Miscellaneous income, net of expenses, was comparable between years in the Merchant Generation Segment and at Genco. 2010 versus 2009 A meren Corporation Miscellaneous income, net of expenses, increased by $9 million in 2010 compared with 2009, because of items noted below. Variations in miscellaneous income, net of expenses, in Ameren's business segments and for the Ameren Companies between 2010 and 2009 were as follows:
A meren Missouri Miscellaneous income, net of expenses, increased by
$14 million in 2010, primarily because of higher allowance for equity funds used during construction associated with a project to install scrubbers at Ameren Missouri's Sioux energy center, reduced, in part, by increased charitable contributions.
Ameren Illinois Regulated Segment Ameren Illinois had net miscellaneous expense of $6 million in 2010, compared with net miscellaneous income of $2 million in 2009. Interest income decreased by $5 million in 2010 compared with 2009, because the CIPS note receivable from Genco matured on May 1, 2010. Merchant Generation and Genco Miscellaneous income, net of expenses, was comparable between years in the Merchant Generation Segment and at Genco. Interest Charges 2011 versus 2010 A meren Corporation Interest charges decreased by $46 million in 2011 compared with 2010, because of items noted below and because of reduced credit facility borrowings at Ameren. Variations in interest charges in Ameren's business segments and for the Ameren Companies between 2011 and 2010 were as follows:
A meren Missouri Interest charges decreased by $4 million in 2011, primarily because of a reduction in interest charges associated with uncertain tax positions of $6 million, the redemption of $66 million of subordinated deferrable interest debentures in September 2010, and reduced amortization of credit facility fees. Offsetting these favorable items was a reduction in interest charges in 2010 due to the May 2010 MoPSC electric rate order. The rate order resulted in a reduction of interest charges of
$10 million in 2010, through the recording of a regulatory asset for recovery of bank credit facility fees incurred in 2009. Ameren Illinois Regulated Segment Interest charges decreased by $7 million in 2011, primarily because of the redemption of $150 million of senior secured notes in June 2011 and the redemption of
$40 million of first mortgage bonds in September 2010.
Table of Contents50 Merchant Generation Interest charges decreased by $28 million in 2011 in the Merchant Generation segment because of items discussed below at Genco, and because of reduced intercompany borrowings at AERG. Genco Interest charges decreased by $15 million in 2011 at Genco, primarily because of the maturity and repayment of $200 million of senior unsecured notes in November 2010. 2010 versus 2009 A meren Corporation Interest charges decreased by $11 million in 2010 compared with 2009, because of items noted below. The decreases below were mitigated by additional interest charges resulting from the issuance of $425 million of senior notes by Ameren in May 2009. Variations in interest charges in Ameren's business segments and for the Ameren Companies between 2010 and 2009 were as follows:
A meren Missouri Interest charges decreased by $16 million in 2010. Interest charges were reduced by $10 million because of a May 2010 MoPSC electric rate order, as discussed above. Additionally, interest charges were reduced by an increase in allowance for borrowed funds used during construction associated with a project to install scrubbers at the Sioux energy center. Partially reducing the above benefits was an increase in interest charges associated with the issuance of $350 million of senior secured notes
in March 2009.
Ameren Illinois Regulated Segment Interest charges decreased by $10 million in 2010, primarily because of the maturity of $250 million of first mortgage bonds in June 2009. Merchant Generation and Genco Interest charges increased by $14 million in 2010 in the Merchant Generation segment and $17 million at Genco, primarily because of the issuance of $250 million of senior unsecured notes at Genco in November 2009.

See Note 17 -
Goodwill, Impairment and Other Charges under Part II, Item 8, of this report for additional information on the
goodwill impairment charges. In addition, there was a noncash, after-tax charge to earnings of $13 million, in the first quarter of 2010, to reduce deferred tax assets.
The charge to earnings was recorded because of legislation enacted in the first quarter of 2010 that resulted in retiree health care costs no longer being deductible for tax purposes to the extent an employer's postretirement health care plan receives federal subsidies that provide retiree prescription drug benefits equivalent to Medicare prescription drug benefits. This was offset, in part, by the impact of the increased Illinois statutory tax rate effective at the beginning of 2011, along with lower favorable net amortization of property-related regulatory assets and liabilities in 2011 compared with 2010, changes to reserves for uncertain tax positions, and the decreased impact of federal and state tax credits. Variations in effective tax rates in Ameren's business segments and for the Ameren Companies between 2011 and 2010 were as follows:
A meren Missouri Ameren Missouri's effective tax rate was higher, primarily because of lower favorable net amortization of property-related regulatory assets and liabilities in 2011 compared to 2010, offset, in part, by the effect of the change in the tax treatment of retiree health care costs in 2010 and changes to reserves for uncertain tax positions.
Ameren Illinois Regulated Segment Ameren Illinois Regulated Segment's effective tax rate was comparable between years. Merchant Generation The effective tax rate was higher in the Merchant Generation segment, primarily because of items detailed below at Genco. (a)The effective tax rate was 36% for 2010, after excluding the impact of the goodwill impairment charge, which is not deductible for income tax purposes. (b)The effective tax rate was 40% for 2010, after excluding the impact of the goodwill impairment charge, which is not deductible for income tax purposes. (c)The effective tax rate was 30% for 2010, after excluding the impact of the goodwill impairment charge, which is not deductible for income tax purposes.
Table of ContentsGenco Genco's effective tax rate was higher, after excluding the impact of the nondeductible goodwill impairment charge, primarily due to the increase in the Illinois statutory income tax rate in 2011, decreased Internal Revenue Code Section 199 product ion activity deductions and lower benefits from state tax credits related to capital investments, offset by favorable changes to reserves for uncertain tax positions in 2011, compared to unfavorable changes in 2010, and the decrease in the effective tax rate from the effect of the change in the tax treatment of retiree health care costs in 2010. 2010 versus 2009 A meren Corporation Ameren's effective tax rate was higher in 2010 than in 2009, primarily due to the unfavorable impact of the goodwill impairment charge and the effect of the change in the tax treatment of retiree health care costs. Additional variations are discussed below. Variations in effective tax rates for Ameren's business segments and for the Ameren Companies between 2010 and 2009 were as follows.
A meren Missouri Ameren Missouri's effective tax rate was higher, primarily because of the change in tax treatment of retiree health care costs, along with the decreased impact of favorable net amortization of property-related regulatory assets and liabilities and other permanent items on higher pretax book income.
Ameren Illinois Regulated Segment The effective tax rate was higher, primarily because of the decreased impact of favorable net amortization of property-related regulatory assets and liabilities and permanent items on higher pretax book income. Merchant Generation The effective tax rate was lower in the Merchant Generation segment, because of items detailed below at Genco, partially offset by the impact of state tax credits related to capital investments and decreased Internal
Revenue Code Section 199 product ion activity deductions on a pretax book loss. Genco The effective tax rate increased, after the impact of the nondeductible goodwill impairment charge was excluded, primarily because of the change in tax treatment of retiree health care costs and changes to reserves for uncertain tax positions mitigated by the increased impact of state tax credits, Internal Revenue Code Section 199 production activity deductions, and investment tax credit amortization on lower pretax book income. Income from Discontinued Operations, Net of Tax A meren Illinois On October 1, 2010, Ameren, CIPS, CILCO, IP, AERG and AER completed a two-step corporate internal reorganization. The first step of the reorganization was the Ameren Illinois Merger. The second step of the reorganization involved the distribution of AERG stock from Ameren Illinois to Ameren and the subsequent contribution by Ameren of the AERG stock to AER. Ameren Illinois determined that the operating results of AERG qualified for discontinu ed operations presentation. We have therefore segregated AERG's operating results and presented them separately as discontinued operations for all periods presented prior to October 1, 2010, in this report. For Ameren's financial statements, AERG's results of operation remain classified as continuing operations. See Note 16 - Corporate Reorganization and Discontinued Operations under Part II, Item 8, of this report for additional information. Ameren Illinois' income from discontinued operations (AERG) decreased $74 million in 2010, compared with 2009. AERG's results of operations were included in Ameren Illinois' consolidated statement of income for all periods prior to October 1, 2010. The inclusion of only nine months in 2010 contributed to the decrease in income from discontinued operations as well as a decrease in electric margins caused by lower realized revenue per megawatt sold and higher fuel and related transportation costs. The decrease was partially offset by a reduction in income tax expense primarily caused by lower pretax book income. LIQUIDITY AND CAPITAL RESOURCES The tariff-based gross margins of Ameren's rate-regulated utility operating companies continue to be a principal source of cash from operating activities for Ameren and its rate-regulated subsidiaries. A diversified retail customer mix of primarily rate-regulated residential, commercial, and industrial classes and a commodity mix
of natural gas and electric service provide a reasonably predictable source of cash flows for Ameren, Ameren Missouri and Ameren Illinois. For operating cash flows, Genco, through Marketing Company, sells power through
primarily market-based contracts with wholesale and retail customers. In addition to using cash flows from operating
activities, the Ameren Companies use available cash, credit facility borrowings, commercial paper issuances, money pool borrowings, or other short-term borrowings from affiliates to support normal operations and other temporary capital requirements. The Ameren Companies may reduce their credit facility or short-term borrowings with cash from operations or, at their discretion, with long-term borrowings or, in the case of Ameren subsidiaries, with equity infusions from Ameren. The Ameren
Companies expect to incur significant capital expenditures over the next five years as they comply with environmental regulations and make significant investments in their electric and natural gas utility infrastructure to support overall system reliability and Table of ContentsThe following table presents net cash provided by (used in) operating, investing and financing activities for the years ended December 31, 2011, 2010, and 2009: 52 Net Cash Provided By Operating ActivitiesNet Cash (Used In)Investing ActivitiesNet Cash Provided By(Used In) Financing Activities 2011 20102009201120102009201120102009 A meren$ 1,878 $ 1,823 $ 1,967 $ (1,048) $ (1,096) $ (1,781) $ (1,120) $ (804) $ 344 Ameren Missouri 1,056 969 975 (627) (700) (957) (430) (334)249 Ameren Illinois 504 593 845 (296)(247)(442)(509)(330)(147)Genco 215 304 253 (141) (29) (389) (72) (275)139 (a)Includes amounts for Ameren re gistrant and nonre gistrant subsidiaries and intercompan y eliminations. other improvements. Ameren intends to finance those capital expenditures and investments with a blend of equity and debt so that it maintains a capital structure in its rate-regulated businesses of approximately 50% to 55% equity, assuming constructive regulatory environments. Ameren, Ameren Missouri and Ameren Illinois plan to implement their long-term financing plans for debt, equity, or equity-linked securities in order to finance their operations appropriately, meet scheduled debt maturities, and maintain financial strength and flexibility. Genco and the Merchant Generation segment seek to fund their operations internally and therefore seek not to rely on financing from Ameren or external, third-party sources. Genco and the Merchant Generation segment will continue to seek to defer capital and operating expenses, sell certain assets, and take other actions as necessary to fund their operations internally while maintaining safe and reliable operations. Under its indenture, Genco may not borrow additional funds from external, third-party sources if its interest coverage ratio is less than a specified minimum or its leverage ratio is greater than a specified maximum. See Note 5 - Long-term Debt and Equity Financings under Part II, Item 8, of this report for additional information on Genco's indenture provisions. Based on projections as of December 31, 2011, of Genco's operating results and cash flows, we expect that, by the end of the first quarter of 2013, Genco's interest coverage ratio will be less than the minimum ratio required for the company to borrow additional funds from external, third-party sources.
Genco's indenture does not restrict intercompany borrowings from Ameren's non-state-regulated subsidiary money pool. However, borrowings from the money pool are subject to Ameren's control, and if a Genco intercompany financing need were to arise, borrowings from the non-state-regulated subsidiary money pool by Genco would be dependent on consideration by Ameren of the facts and circumstances existing at that time. (a)Cash Flows from Operating Activities 2011 versus 2010
Ameren Corporation Ameren's cash from operating activities increased in 2011, compared with 2010. The following items contributed to the increase in cash from operating activities during 2011, compared with 2010: Ameren Missouri's regulatory asset for FAC under-recovery decreased by $216 million as more deferred costs were recovered from customers durin g 2011. Trade accounts receivable and unbilled revenues balances decreased, primarily because of milder weather in the fourth quarter of 2011, compared with the fourth quarter of 2010. Those same weather conditions caused accounts payable balances to MISO and natural gas suppliers to decrease as less
power and natural gas was purchased. Additionally, during 2011, MISO shortened the length of its settlement terms for all of its members. The new terms resulted in an acceleration of payments that previously would not have been paid until 2012. These factors resulted in a net increase of $120 million in cash from operating activities in 2011 compared with 2010. A net $100 million decrease in collateral posted with counterparties due primarily to the items discussed at
the re gistrant subsidiaries below, partiall y offset b y a The following items reduced the increase in Ameren's cash from operating activities during 2011, compared with 2010: decrease in collateral returned from Ameren counterparties of $10 million and additional collateral posted to counterparties of $4 million due to changes
in the market price of power. Deferred budget billing receivables decreased by
$71 million, partially as a result of milder weather. A $45 million decrease in interest payments, primarily due to the long-term debt redemptions at the
registrant subsidiaries discussed below and a reduction in Ameren's borrowings under its credit facility agreements, which resulted in an $11 million reduction in interest pa y ments.An $11 million reduction in payments for scheduled nuclear refueling and maintenance outages at the Callaway energy center caused primarily by the timing of the 2011 outage compared with the 2010 outage, which had unpaid liabilities as of December 31, 2011. A $115 million increase in pension and OPEB plan contributions. Ameren Illinois contributed to Ameren's postretirement benefit VEBA trust an incremental

The following
items contributed to the increase in cash from operating activities during 2011, compared with 2010:
excludin g impacts of noncash MTM transactions. During 2010, Ameren's Merchant Generation coal-fired energy centers, significantly reduced their coal inventory levels, which resulted in an estimated
$64 million cash savings in excess of the smaller inventory reduction that occurred in 2011. A $55 million decrease associated with the December 2005 Taum Sauk incident, primarily as a result of insurance recoveries received in 2010, but not in 2011. A $34 million increase in major storm restorationcosts. A $31 million decrease in income tax refunds. The 2010 refund resulted primarily from a 2009 change in tax treatment of electric generation plant expenditures while the 2011 refund resulted primarily from casualty loss deductions due to an Internal Revenue Service audit settlement. Ameren did not make any federal income tax payments in 2011 because of accelerated deductions authorized by economic stimulus legislation, use of its net operating loss carryforwards, and other deductions. A $30 million increase in taxes other than income tax payments related to higher assessed property tax values for energy center enhancements, county property tax rate increases, the timing of property tax payments at each year end for Ameren Missouri. Ameren Illinois incurred an increase in electricity distribution and invested capital tax payments resulting from the tiered rate structure for the merged entit y.Reduced collections as more utility customers were past due on their bills on December 31, 2011, than on December 31, 2010. Additionally, write-offs of customer receivable balances increased because of economic conditions. An $18 million increase in Ameren Missouri receivables held in court registries under the appeals of the MoPSC's 2009 and 2010 rate orders. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report for additional information. A $16 million decrease in Ameren Illinois' electric purchased power commodity over-recovered costs. A $15 million increase in energy efficiency expenditures for new customer programs.

A $7 million increase in preliminary study expenditures, primarily at Ameren Missouri for environmental compliance testing. The regulatory asset for FAC under-recovery The following items reduced the increase in Ameren Missouri's cash from operating activities during 2011, compared with 2010: Trade accounts receivable and unbilled revenue balances decreased by $65 million, primarily because of milder weather in the fourth quarter of 2011, compared with the fourth quarter of 2010. Deferred budget billing receivables decreased by
$33 million, partially as a result of milder weather. Electric and natural gas margins, as discussed in Results of Operations, increased by $25 million, excludin g impacts of noncash MTM transactions. A $16 million decrease in payments associated with major outages at coal-fired energy centers, primarily because the scope of the major outages in 2011 were not as extensive as the scope of the major outages performed in 2010. An $11 million reduction in payments due to the timing of scheduled nuclear refueling and maintenance outages at the Callaway energy center as discussed above. A $4 million decrease in interest payments, primarily due to the redemption of subordinated deferrable interest debentures in September 2010. Income tax payments of $9 million in 2011, compared with income tax refunds of $106 million in 2010. The 2010 refund resulted primarily from a 2009 change in tax treatment of electric generation plant expenditures and accelerated deductions authorized by economic stimulus legislation. Ameren Missouri's 2011 tax
liability was reduced by accelerated deductions authorized by economic stimulus legislation, use of its net operating loss carryforwards, and other

Electric margins, as discussed in Result of Operations, decreased by $63 million, excluding impacts of noncash MTM transactions. During 2010, Genco significantly reduced the volume of its coal inventory, which resulted in an estimated
$43 million cash savings in excess of the smaller inventory reduction that occurred in 2011. The January 2010 receipt from Marketing Company for December 2009 generation output was $16 million higher than the January 2011 receipt for December 2010 generation output. This was primarily caused by the inclusion of higher-priced sales contracts from the 2006 Illinois power procurement auction, which expired in Ma y 2010. A $9 million increase in payments associated with major outages at coal-fired energy centers, primarily because the scope of the major outages in 2011 were more extensive than the scope of the major outages performed in 2010. An $8 million increase in pension plan contributions as EEI made a contribution in 2011, but made no
contribution in 2010. Income tax refunds of $25 million in 2011, compared with income tax payments of $1 million in 2010. The 2011 refund was primarily due to an increase in accelerated depreciation deductions authorized by the economic stimulus legislation. Genco did not make any federal income tax payments in 2011 primarily because of accelerated deductions related to pollution control equipment, economic stimulus legislation and deductions related to the closure of Meredosia and Hutsonville ener gy centers. A $20 million decrease in interest payments, primarily due to the redemption of senior notes in November 2010.

The following items reduced the decrease in Ameren's cash from operating activities during 2010, compared with 2009: A $116 million decrease in billed revenues, net of payments to suppliers, for pass-through natural gas commodity costs primarily caused by higher-priced natural gas injected into storage during 2008 and
billed to customers in 2009. Accounts receivable and unbilled revenue balances increased by $106 million, primarily because of higher utility rates and colder December weather in 2010, compared with December 2009. Deferred FAC costs increased $100 million as net base fuel costs incurred at Ameren Missouri exceeded the amounts allowed in base rates due to higher fuel costs and lower off-system sales as a result of warmer weather increasing native load
demand. Deferred budget billing balances increased by
$74 million, partially as a result of warmer summer weather, which increased sales volumes over budget-billed amounts.

55 refund primarily resulted from an acceleration of Table of Contents Ameren Illinois Ameren Illinois' cash from operating activities decreased in 2010 compared with 2009. Ameren Illinois' cash from operating activities included AERG's operating cash flows for all periods prior to October 1, 2010, which were presented as discontinued operations in Ameren Illinois' consolidated statement of cash flows. Excluding the impacts of discontinued operations, Ameren Illinois' cash from operating activities decreased in 2010 compared with 2009. The following items contributed to the decrease in cash from operating activities associated with continuing operations duri ng 2010, compared with 2009: The following items reduced the decrease in Ameren Illinois' cash from operating activities associated with
continuing operations during 2010, compared with 2009: A $192 million increase in collateral posted with counterparties due, in part, to changes in the market price of natural gas and collateral posting requirements. Accounts receivable and unbilled revenue balances increased by $183 million, primarily because of higher utility rates and colder December weather in 2010, compared with December 2009. A $98 million decrease in billed revenues, net of payments to suppliers, for pass-through natural gas commodity costs primarily caused by higher-priced natural gas injected into storage during 2008 and
billed to customers in 2009. Deferred budget billing balances increased by
$60 million, partially as a result of warmer summer weather, which increased sales volumes over budget billed amounts. A $10 million one-time donation in 2010 for customer assistance programs required by the 2009 Illinois legislation that authorized the bad debt rate ad justment mechanism. Payments for professional services, additional franchise taxes, and other administrative items
necessary to complete the Ameren Illinois Merger and AERG distribution, which totaled $7 million. In 2009, Ameren Illinois received $5 million from Marketing Company for the costs of upgrades to Ameren Illinois' electric transmission system. There was no such receipt in 2010. Electric and natural gas margins, as discussed in Results of Operations, increased by $187 million, excluding the noncash impacts of MTM transactions. Income tax refunds of $52 million in 2010, compared with income tax payments of $61 million in 2009. The refund resulted primarily from an acceleration of depreciation deductions authorized by economic stimulus le g islation.A $19 million decrease in major storm restoration costs. Contributions to the pension an d postretirement plans were $11 million lower in 2010. A $6 million decrease in interest payments, primarily because of the first mort gage bond maturity in June 2009. Ameren Illinois' cash from operating activities associated with discontinued operations decreased in 2010 compared with 2009. AERG's cash flows were included in Ameren Illinois' consolidated statement of cash flows for all periods prior to October 1, 2010. The inclusion of only nine months in 2010 was the primary cause of the decrease in cash flows, along with a
reduction in receipts from Marketing Company under the AERG PSA, primarily due to lower market prices. A decrease in income tax payment s, primarily due to lower pretax book income, and an a cceleration of depreciation deductions authorized by economic stimulus legislation partially offset the decrease in AERG's operating cash
flows. Genco Genco's cash from operating activities increased in 2010 compared with 2009. The following items contributed to the increase in cash from operating activities during 2010, compared with 2009: The following items reduced the increase in Genco's cash from operating activities during 2010, compared with 2009: Pension Funding Ameren's pension plans are funded in compliance with income tax regulations and to meet federal funding or regulatory requirements. As a result, Ameren expects to fund its pension plans at a lev el equal to the greater of the pension expense or the legally required minimum
contribution. Considering Ameren's assumptions at December 31, 2011, its investment performance in 2011, and its pension funding policy, Ameren expects to make annual contributions of $90 million to $150 million in each of the next five years, with aggregate estimated A $73 million decrease in income tax payments, primarily due to lower pretax book income, deductions relating to environmental expenditures, and an acceleration of depreciation deductions authorized by economic stimulus le g islation.Reduced coal inventory levels in 2010, which are estimated to have resulted in cash savings of
$50 million in 2010. Lower labor expenditures resulting from staff reductions and fewer major outages at its coal-fired plants. A $7 million reduction in use tax payments as Genco and EEI began claiming tax exemptions and credits for purchase transactions related to their generation
operations. Contributions to the pension plans were $6 million lower in 2010. Electric margins, as discussed in Result of Operations, decreased by $99 million, excluding impacts of noncash MTM transactions. A $13 million increase in interest payments, primarily due to the senior unsecured notes issued in November 2009, which required interest payments in 2010, but not in 2009.
56 contributions of $580 million. We expect Ameren Table of ContentsMissouri's, Ameren Illinois', and Genco's portion of the future funding requirements to be 51%, 33% and 12%, respectively. These amounts are estimates. The estimates may change with actual investment performance, changes in interest rates, changes in our assumptions, any pertinent changes in government regulations, and any voluntary contributions. In 2011, Ameren contributed $103 million to its pension plans. See Note 11 - Retirement Benefits under Part II, Item 8, of this report for additional information. Cash Flows from Investing Activities 2011 versus 2010 Ameren's cash used in investing activities decreased by $48 million during 2011, compared with 2010. In 2011, cash flows from investing activities benefited from an increase of proceeds from property sales as well as
$8 million in proceeds from the sale of its investment in a leveraged lease and a $9 million payment received from the DOE under the terms of Ameren Missouri's settlement with the DOE in 2011 related to nuclear waste disposal. Net cash used for capital expenditures decreased $12 million during 2011, compared with 2010. Reductions in
capital expenditures caused by the completion of two energy center scrubber projects in 2010 were offset, in part, by an increase in storm-related repair costs, an increase in electric transmission investments, and expenditures for a third energy center scrubber project in 2011. Ameren Missouri's cash used in investing activities decreased by $73 million during 2011, compared with
2010, principally because of a $74 million decrease in
capital expenditures and a $9 million payment received from the DOE in 2011 under the terms of the settlement with the DOE related to nuclear waste disposal. These cash benefits were reduced by a $6 million net decreasein nuclear decommissioning trust fund activities. Capital expenditures were lower in 2011 as a result of the completion in 2010 of two scrubbers at Ameren Missouri's
Sioux energy center and boile r projects, which offset a
$28 million increase in capital expenditures related to storm-related repair costs. Ameren Illinois' cash used in investing activities increased by $49 million during 2011, compared with 2010. There was a $70 million increase in capital expenditures primarily as a result of increased investment in electric transmission assets and a $17 million increase in capital expenditures related to storm-related repair costs. In 2011, cash flows from investing activities benefited from the repayments of advances previously paid to ATXI, as a result of the completion of a project under a joint ownership agreement. In 2010, cash flows from investing activities benefited from the proceeds received on an intercompany note receivable, offset, in part, by advances to ATXI. Genco's cash used in investing activities increased by $112 million during 2011, compared with 2010. Net cash used for capital expenditures increased by $46 million primarily as a result of in creased spendin g for energy center scrubber project. In 2011, cash flows from investing activities benefited from the proceeds of property sales, principally attributed to $45 million of proceeds received from the sale of Genco's remaining interest in its Columbia CT facility. In 2010, cash flows from investing activities benefited from the proceeds received from the sale of 25% of Genco's Columbia CT facility. During 2011, cash provided by sales of properties enabled Genco to contribute net non-state-regulated subsidiaries' money pool advances of $49 million. During 2010, Genco received $48 million in net repayment of non-state-regulated subsidiaries' money pool advances. 2010 versus 2009 Ameren's cash used in investing activities decreased by $685 million during 2010, compared with 2009. There was a $668 million decrease in capital expenditures as compared with 2009 as a result of reductions in planned capital expenditures for the distribution system and energy center improvements during 2010, a $109 million reduction in capital expenditures to repair severe storm damage, and the completion of energy center scrubber projects in the Merchant Generation segment during 2009 and early 2010. Cash flows from investing activities in 2010 also benefited from the sale of 25% of Genco's Columbia CT facility and other properties. Ameren Missouri's cash used in investing activities decreased by $257 million during 2010, compared with 2009. There was a $258 million decrease in capital expenditures as compared with 2009 as a result of reductions in planned capital expenditures for the distribution system and energy center improvements during 2010, as well as a $74 million reduction in capital expenditures to repair severe storm damage. This cash benefit was reduced by a $12 million net decrease in nuclear decommissioning trust fund activities. Ameren Illinois' cash used in investing activities decreased by $195 million during 2010, compared with 2009. There was a $71 million decrease in capital
expenditures compared with 2009 because Ameren Illinois reduced planned capital expenditures for the distribution system during 2010 after receiving significantly less than it requested in a rate proceeding, as well as a $35 million reduction in capital expenditures to repair severe storm damage. Similar planned capital expenditure reductions at AER G resulted in the $85 million decrease in capital expenditures of discontinued operations. Additionally, Ameren Illinois' advances to ATXI for construction under a joint ownership agreement decreased during 2010 as the project approached completion. Ameren Illinois received funding for this construction under a generator interconnection agreement related to ongoing transmission upgrade projects. Genco's cash used in investing activities decreased by $360 million during 2010, compared with 2009. Reductions in planned capital expenditures, as well as completion of energy center scrubber projects during 2009, resulted in a $221 million decrease in capital expenditures compared with 2009.

Capital Expenditures The following table presents the capital expenditures by the Ameren Companies for the years ended December 31, 2011, 2010, and 2009: Ameren's 2011 capital expenditures principally consisted of the following expenditures at its subsidiaries.
Ameren Missouri spent $24 million on building its
Maryland Heights energy center and $31 million for storm-related repair costs. Ameren Illinois incurred storm-related repair costs of $20 million. Genco spent $75 million toward scrubbers at its Newton and Coffeen energy centers for compliance with environmental regulations. Other capital expenditures were made principally to maintain, upgrade, and expand the reliability of the transmission and distribution systems of Ameren Missouri and Ameren Illinois, as well as to fund various energy center upgrades. Ameren's 2010 capital expenditures principally consisted of the following expenditures at its subsidiaries.
Ameren Missouri spent $130 million toward two scrubbers at its Sioux energy center, which were completed in 2010.
At Genco, there was a cash outlay of $29 million for energy center scrubber pr ojects. The scrubbers are necessary to comply with environmental regulations. Other capital expenditures were made principally to
maintain, upgrade, and expand the reliability of the transmission and distribution systems of Ameren Missouri and Ameren Illinois, as well as to fund various energy
center upgrades. Ameren's 2009 capital ex penditures consisted principally of the following expenditures at its subsidiaries. Ameren Missouri spent $173 million toward two scrubbers at its Sioux energy center, $93 million toward the Taum Sauk rebuild, and it incurred storm-related expenditures of $78 million. Ameren Illinois incurred storm-related repair costs of $38 million. At Genco, there was a cash outlay of $169 million for energy center scrubber projects. The scrubbers are necessary to comply with environmental regulations. Other capital expenditures were made principally to maintain, upgrade, and expand
the reliability of the transmission and distribution systems of Ameren Missouri and Ameren Illinois as well as various energy center upgrades.

(a)The following table estimates the capital expenditures that will be incurred by the Ameren Companies from 2012 through 2016, including construction expenditures, capitalized interest for the Merchant Generation business, allowance for funds used during construction for our rate-regulated utility businesses, and estimated expenditures
for compliance with known and existing environmental regulations. As a result of a sharp decline in forward power prices in early 2012, as well as uncertain environmental regulations, Genco is decelerating the construction of two scrubbers at its Newton energy center, and AERG has removed the previously planned precipitator upgrades at its E.D. Edwards energy center from the five-year capital expenditures forecast. Genco
will continue to incur some ongoing capital costs related to the construction of the Newton scrubbers. The table below includes Genco's estimated capital expenditures of approximately $150 million in 2012 and approximately $20 million annually from 2013 through 2016 for the installation of the two scrubbers, excluding capitalized interest. See Outlook and also Note 15 - Commitments and Contingencies under Part II, Item 8, of this report for further discussion of the impact of declining power prices on the Merchant Generation segment. Ameren Missouri's estimated capital expenditures include transmission, distribution, and generation-related investments, as well as expenditures for compliance with environmental regulations discussed below. Ameren Illinois' estimated capital expenditures are primarily for electric and natural gas transmission and distribution-related investments, and ex pected capital expenditures incremental to historical average electric delivery capital expenditures to modernize its distribution system pursuant to the IEIMA. For additional information on the IEIMA, see Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report. Genco's estimated capital expenditures are primarily for compliance with environmental regulations and upgrades to existing coal and natural gas-fir ed energy cente rs discussed below. Estimated capital expenditures of Ameren nonregistrant subsidiaries consist primarily of AERG's estimated expenditures for compliance with environmental regulations discussed below and ATX/ATXI's estimated transmission expenditures. We continually review our generation portfolio and expected power needs. As a result, we could modify our plan for generation capacity, which could include changing the times when certain assets will be added to or removed from our portfolio, the type of generation asset technology that will be employed, and whether 20122013 - 2016Total Ameren Missouri$665 $2,190 - $2,960 $2,855 - $3,625 Ameren Illinois535 2,020 - 2,730 2,555 - 3,265 Merchant Generation-Genco175 165 - 220 340 - 395 Merchant Generation-Othe r5 35 - 50 40 - 55 ATX/ATXI25 625 - 845 650 - 870 Othe r (10) 45 - 65 35 - 55 Ameren$1,395 $ 5,080 -$ 6,870 $6,475 - $8,265 (a)Includes the eliminations of intercompany transfers.

Additionally, we continually review the reliability of our transmission and distribution systems, expected capacity needs, and opportunities for transmission investments. The timing and amount of investment could vary due to changes in expected capacity, the condition of transmission and distribution systems, and the ability and willingness to pursue transmission investments, among other things. Any changes that we may plan to make for future generation, transmission or distribution needs could result in significant capital expenditures or losses being incurred, which could be material. Environmental Capital Expenditures Ameren, Ameren Missouri and Genco will incur significant costs in future years to comply with existing and known federal and state regulations regarding SO, NO, and mercury emissions from coal-fired power plants. See Note 15 - Commitments and Contingencies under Part II, Item 8, of this report for a discussion of existing environmental laws and regulations that affect, or may affect, our facilities and capital costs to comply with such laws and regulations, as well as our assessment of the potential impacts of the EPA's proposed regulation of CCR and cooling water intake structures, the MATS, the stayed CSAPR, and the revised national ambient air quality standards for SO and NO emissions as of December 31, 2011. Cash Flows from Financing Activities 2011 versus 2010 During 2011, we reduced our reliance on borrowings from short-term debt and credit facilities, and we reduced long-term debt outstanding while maintaining adequate cash balances for working capital needs.
Ameren's cash used in financing activities increased in 2011, compared with 2010. During 2011, Ameren's cash flow from operating activities of $1.9 billion exceeded its capital expenditures of $1.0 billion and
common stock dividend requirements of $375 million.
Ameren used this cash as well as cash on hand to repay $581 million of short-term debt and credit facility borrowings, to redeem $155 million of long-term debt, and to repay $73 million of advances previously received from generators due to project completion. During 2010, Ameren redeemed $310 million of long-term debt and $52 million of preferred stock. Ameren Missouri's cash used in financing activities increased by $96 million in 2011, compared with 2010. During 2011, Ameren Missouri's cash flow from operating activities of $1.1 billion exceeded its combined capital and nuclear fuel expenditures of $612 million. Ameren Missouri utilized this cash to pay common stock dividends of $403 million and repay $19 million of advances previously received from generators due to project completion. During 2010, Ameren Missouri paid common stock dividends of 2 x 2x$235 million; redeemed $70 million of long-term debt, including its 7.69% Series A subordinated debentures; and redeemed all outstanding shares of its $7.64 Series preferred stock. Ameren Illinois' net cash used in financing activities increased by $179 million in 2011 compared with 2010. Ameren Illinois' common stock dividend increased
$194 million compared with 2010. In June 2011, Ameren Illinois' 6.625% $150 million senior secured notes matured and were repaid and retired using available cash on hand. During 2010, in connection with the Ameren Illinois Merger, Ameren Illinois (formerly CILCO) redeemed all of its preferred stock and all $40 million of its 7.61% Series 1997-2 first mortgage bonds (formerly CIPS). Net repayments of generator advances received for construction increased $25 million in 2011 compared with 2010. Genco's net cash used in financing activities decreased by $203 million in 2011 compared with 2010. During 2011, Genco's cash flow from operating activities of $215 million exceeded its capital expenditures of $141 million. Additionally, Genco received a capital contribution from Ameren associated with a tax allocation agreement that benefited 2011 cash flows from financing activities.
Genco used this cash to reduce its reliance on credit facility borrowings. In 2010, Genco repaid at maturity
$200 million of its 8.35% senior notes at maturity and repaid a net $176 million of intercompany note borrowings. These 2010 cash outlays were offset, in part, by credit facility borrowings. 2010 versus 2009 During 2010, we replaced and extended the expiration of our credit facilities. We sought to reduce our reliance on borrowings from our credit facilities and to reduce long-term debt outstanding while maintaining adequate cash balances for working capital needs. Ameren had an $804 million net use of cash from financing activities in 2010, compared with a $344 million net source of cash in 2009. During 2010, Ameren's cash flow from operating activities of $1.8 billion exceeded its
capital expenditures of $1.0 billion and common stock dividend requirements of $368 million. Ameren used this cash to redeem $310 million of long-term debt and
$52 million of preferred stock in 2010. During 2009, Ameren issued $1 billion of senior debt and $634 million in common stock. It used the proceeds to repurchase, redeem, and fund maturities of $631 million of long-term
debt, to reduce short-term bo rrowings, and to fund capital expenditures and other working capital needs at Ameren Missouri, Ameren Illinois, and Genco. Ameren Missouri had a $334 million net use of cash from financing activities in 2010, compared with a
$249 million net source of cash in 2009. Planned
reductions of expenditures allowed Ameren Missouri to use cash from operations and credit facility borrowings to fund its capital expenditures and working capital needs without issuing additional senior debt or capital
contributions from Table of Contents60 Ameren. Additionally, during 2010, these efforts allowed Ameren Missouri to redeem $70 million of long-term debt, including its 7.69% Series A subordinated debentures; to redeem all outstanding shares of its $7.64 Series preferred stock; to increase common stock dividends by $60 million; and to reduce short-term and intercompany borrowing repayments by $343 million, compared with 2009. Ameren Illinois' net cash used in financing activities increased by $183 million in 2010 compared with 2009.
Reduction of planned expenditures allowed it to use cash from operations to fund its capital expenditures and working capital needs without the issuance of additional senior debt or capital contributions from Ameren.
Additionally, Ameren Illinois' common stock dividends increased $35 million compared with 2009, and CILCO redeemed all of its preferr ed stock in connection with the Ameren Illinois Merger. During 2009, Ameren made capital contributions to Ameren Illinois of $272 million and Ameren Illinois repaid $250 million of long-term debt and
$62 million of short-term borrowing balances. Genco had a $275 million net use of cash from financing activities in 2010, compared with a $139 million net source of cash in 2009, primarily as a result of reductions of planned expen ditures. These efforts allowed Genco to use cash from operations and credit facility
borrowings to fund capital expenditures, to meet working capital needs, to repay its $200 million of 8.35% senior notes at maturity, and to repay a net $176 million of
intercompany note borrowings in 2010. During 2009, Genco issued $249 million of long-term debt and used the proceeds to repay short-term borrowings and to fund general corporate purposes. Credit Facility Borrowings and Liquidity The liquidity needs of the Ameren Companies are typically supported through the use of available cash, short-term intercompany borrowings, drawings under committed bank credit facilities, or commercial paper issuances. See Note 4 - Short-Term Debt and Liquidity under Part II, Item 8, of this report for additional information on credit facilities, short-term borrowing activity, commercial paper activity, relevant interest rates, and borrowings under Ameren's utility and non-state-
regulated subsidiary mone y pool arrangements.

(a)(a)(a)In February 2011, Ameren Illinois received approval from the ICC to extend the expiration of its borrowing sublimit under the 2010 Illinois Credit Agreement to September 10, 2013. In June 2011, Ameren Missouri
received approval from the MoPSC to extend the expiration of its borrowing sublimit under the 2010 Missouri Credit Agreement to September 10, 2013. The 2010 Credit Agreements are used to make cash borrowings, to issue letters of credit, and to support borrowings under Ameren's $500 million commercial paper program, Ameren Missouri's $500 million
commercial paper program, and Ameren Illinois' $500 million commercial paper program, the latter of which was created in October 2011. Any of the 2010 Credit Agreements are available to Ameren to support borrowings under Ameren's commercial paper program, subject to borrowing sublimits. The 2010 Missouri Credit Agreement is available to support borrowings under Ameren Missouri's commercial paper program, and the 2010 Illinois Credit Agreement is available to support borrowings under Ameren Illinois' commercial paper program. The maximum aggregate amount available to each borrower under each facility is shown in the following table (such amount being such borrower's "Borrowing Sublimit"):These credit agreements were also available for use, subject to applicable regulatory short-term borrowing authorizations, by EEI or by other Ameren non-state-regulated subsidiaries through direct short-term borrowings from Ameren and by most of Ameren's non-rate-regulated subsidiaries, including, but not limited to, Ameren Services, AER, AERG and Marketing Company, through a non-state-regulated subsidiary money pool agreement.

Separate money pools are maintained for utility and non-state-regulated entities. In addition, a unilateral borrowing agreement among Ameren, Ameren Illinois, and Ameren Services enables Ameren Illinois to make short-term borrowings directly from Ameren. Pursuant to the terms of the unilateral borrowing agreement, the aggregate amount of borrowings outstanding at any time by Ameren Illinois under the unilateral borrowing agreement and the utility money pool agreement, together with any outstanding Ameren Illinois external credit facility borrowings or commercial paper issuances, may not exceed $500 million, pursuant to authorization from the ICC. Ameren Illinois did not borrow under the unilateral borrowing agreement during 2011 or 2010. Ameren Services is responsible for operation and administration of the money pool agreements. See Note 4 - Short-Term Debt and Liquidity under Part II, Item 8, of this report for a detailed explanation of the money pool arrangements and the unilateral borrowing agreement. The issuance of short-term debt securities by Ameren's utility subsidiaries is subject to approval by FERC under the Federal Power Act. In March 2010, FERC issued an order authorizing the issuance of up to $1 billion of short-term debt securities for Ameren Missouri. The authorization was effective as of April 1, 2010, and terminates on March 31, 2012. On October 1, 2010, FERC authorized Ameren Illinois to issue up to $1
billion of short-term debt securities. The authorization became effective immediately and terminates on September 30, 2012. Genco has unlimited long and short-term debt issuance authorization from FERC. EEI has unlimited short-term debt authorization from FERC. The issuance of short-term debt securities by Ameren is not subject to approval by any regulatory body. The Ameren Companies continually evaluate the adequacy and appropriateness of their liquidity
arrangements given changing business conditions. When business conditions warrant, changes may be made to existing credit facilities or to other short-term borrowing arrangements.

Table of ContentsA Form S-3 registration statement filed by Ameren with the SEC in June 2011 authorized the offering of 6 million additional shares of its common stock under DRPlus. Shares of common stock sold under DRPlus are, at Ameren's option, newly issued shares, treasury shares, or shares purchased in the open market or in privately negotiated transactions. In 2012, Ameren plans for shares to be purchased in the open market for DRPlus and its 401(k) plan. Under DRPlus and its 401(k) plan, Ameren issued 2.2 million, 3.0 million, and 3.2 million shares of common stock in 2011, 2010, and 2009, respectively, which were valued at $65 million, $80 million, and
$82 million for the respective years. In September 2009, Ameren issued and sold 21.85 million shares of its common stock at $25.25 per share, for proceeds of $535 million, net of $17 million of issuance costs. Ameren used the offering proceeds to make investments in its rate-regulated utility subsidiaries in the form of capital contributions to Ameren Missouri and Ameren Illinois of $436 million and $99 million, respectively. The Ameren Companies may sell securities registered under their effective registration statements if market conditions and capital requirements warrant such sales. Any offer and sale will be made only by means of a prospectus that meets the requirements of the Securities Act of 1933 and the rules and regulations thereunder. Indebtedness Provisions and Other Covenants See Note 4 - Short-Term Debt and Liquidity and Note 5 - Long-term Debt and Equity Financings under Part II, Item 8, of this report for a discussion of covenants and provisions (and applicable cross-default provisions) contained in our bank credit and term loan agreements and in certain of the Ameren Companies' indentures and
articles of incorporation. At December 31, 2011, the Ameren Companies were in compliance with the provisions and covenants contained within their credit agreements, indentures, and articles of incorporation provisions and covenants. We consider access to short-term and long-term capital markets a significant source of funding for capital requirements not satisfied by our operating cash flows. Inability to raise capital on reasonable terms, particularly during times of uncertainty in the capital markets, could negatively affect our ability to maintain and expand our businesses. After assessing our current operating performance, liquidity, and credit ratings (see Credit Ratings below), we believe that Ameren and its rate-regulated businesses will continue to have access to the capital markets. However, events beyond our control may create uncertainty in the capital markets or make access to the capital markets uncertain or limited. Such events could increase our cost of capital and adversely affect our ability to access the capital markets. Genco's operating results and operating cash flows are significantly affected by changes in market prices for power, which have significantly decreased over the past few years. Under the provisions of Genco's indenture described in Note 5 - Long-term Debt and Equity Financings, in Part II, Item 8 of this report, Genco may not borrow additional funds from external, third-party sources if its interest coverage ratio is less than a specified minimum or its leverage ratio is greater than a specified maximum. Based on projection s as of December 31, 2011, of Genco's operating results and cash flows, we expect that, by the end of the first quarter of 2013, Genco's interest coverage ratio will be less than the minimum ratio required for the company to borrow additional funds from external, third-party sources. Dividends Ameren paid to its shareholders common stock dividends totaling $375 million, or $1.555 per share, in 2011, $368 million, or $1.54 per share, in 2010, and
$338 million, or $1.54 per share, in 2009. The payout rate based on net income in 2011 and 2009 was 72% and 55%, respectively. The payout of common stock dividends exceeded net income in 2010 because of the noncash goodwill, impairment and other charges recorded during 2010. Dividends paid to common shareholders in relation to net cash provided by operating activities for the same periods were 20% in 2011, 20% in 2010, and 17% in 2009. The amount and timing of dividends payable on Ameren's common stock are within the sole discretion of Ameren's board of directors. The board of directors has not set specific targets or payout parameters when declaring common stock dividends. However, as it has done in the past, the board of directors is expected to consider various issues, including Ameren's overall payout ratio, payout ratios of our peers, projected cash flow and potential future cash flow requirements, historical earnings and cash flow, projected earnings, impacts of regulatory orders or legislation, and other key business considerations. On February 10, 2012, the board of directors of Ameren declared a quarterly dividend on Ameren's common stock of 40 cents per share, payable on March 30, 2012, to stockholders of record on March 14, 2012. Certain of our financial agreements and corporate organizational documents contain covenants and conditions that, among other things, restrict the Ameren Companies' payment of dividends in certain
circumstances.Ameren Illinois' articles of incorporation require its dividend payments on common stock to be based on ratios of common stock to total capitalization and other provisions related to certain operating expenses and accumulations of earned surplus. Genco's indenture includes restrictions that prohibit it from making dividend payments on its common stock.
Specifically, Genco cannot pay dividends on its common stock unless the company's actual interest coverage ratio 63 for the most recently ended four fiscal quarters and the Table of ContentsThe following table presents common stock dividends paid by Ameren Corporation to its common stockholders and by Ameren's registrant subsidiaries to their respective parents. 64 2011 20102009 Ameren Missouri$ 403 $ 235 $ 175 Ameren Illinois 327 133 98 Genco - - 43 Dividends paid b y Ameren 375 368 338 interest coverage ratios projected by management for each of the subsequent four six-month periods are greater than a specified minimum level. Based on projections as of December 31, 2011, of Genco's operating results and cash flows in 2012 and 2013, we did not believe that Genco will achieve the minimum interest coverage ratio necessary to pay dividends on its common stock for the six months ended June 30, 2013, or the six months ended December 31, 2013. As a result, Genco was restricted from paying dividends on its common stock as of December 31, 2011, and we expect Genco will be unable to pay dividends on its common stock in 2012, 2013, and 2014. See Note 5 - Long-term Debt and Equity Financings under Part II, Item 8, of this report for additional information on Genco's indenture provisions. Ameren Missouri, Ameren Illinois and Genco as well as certain other nonregistrant Ameren subsidiaries are subject to Section 305(a) of the Federal Power Act, which makes it unlawful for any officer or director of a public
utility, as defined in the Federal Power Act, to participate in the making or paying of any dividend from any funds "properly included in capital account." The meaning of this
limitationhas never been clarified under the Federal Power Act or FERC regulations. However, FERC has consistently interpreted the provision to allow dividends to be paid as long as (1) the source of the dividends is clearly disclosed, (2) the dividends are not excessive, and (3) there is no self-dealing on the part of corporate officials. At a minimum, Ameren believes that dividends can be paid by its subsidiaries that are public utilities from net income and retained earnings. In addition, under Illinois law, Ameren Illinois may not pay any dividend on its stock unless, among other things, its earnings and earned surplus are sufficient to declare and pay a dividend after provision is made for reasonable and proper reserves, or unless Ameren Illinois has specific authorization from the ICC. In its application for the FERC orders approving the Ameren Illinois Merger and the AERG distribution, Ameren committed itself to maintain a minimum of 30% equity in its capital structure at Ameren Illinois following the Ameren Illinois Merger and the AERG distribution. At December 31, 2011, Ameren, Ameren Missouri and Ameren Illinois were not restricted from paying
dividends. Certain of the Ameren Companies have issued preferred stock, which provides for cumulative preferred stock dividends. Each company's board of directors considers the declaration of the preferred stock dividends to shareholders of record on a certain date, stating the date on which the dividend is payable and the amount to be paid. See Note 5 - Long-term Debt and Equity Financings under Part II, Item 8, of this report for further detail concerning the preferred stock issuances.

(f)(c)(e)(f)As of December 31, 2011, the amounts of unrecognized tax benefits under the authoritative accounting guidance for uncertain tax positions were
$148 million, $124 million, $11 million, and $9 million for Ameren, Ameren Missouri, Ameren Illinois, and Genco, respectively. It is reasonably possible to expect that the settlement of an unrecognized tax benefit will result in an underpayment or overpayment of tax and related interest. However, there is a high degree of uncertainty with respect to the timing of cash payments or receipts associated with unrecognized tax benefits. The amount and timing of certain payments or receipts is not reliably estimable or determinable at this time. See Note 13 - Income Taxes under Part II, Item 8, of this report for information regarding the Ameren Companies' unrecognized tax benefits and related liabilities for interest expense.
Off-Balance-Sheet Arrangements At December 31, 2011, none of the Ameren Companies had off-balance-sheet financing arrangements other than operating leases entered into in the ordinary course of business. None of the Ameren Companies expect to engage in any significant off-
balance-sheet financing arra ngements in the near future.
Table of ContentsCredit Ratings The credit ratings of the Ameren Companies affect our liquidity, our access to th e capital markets and credit markets, our cost of borrowing under our credit facilities and collateral posting requirements under commodity contracts. The following table presents the principal credit ratings of the Ameren Companies by Moody's, S&P, and Fitch effective on the date of this report: The cost of borrowing under our credit facilities can also increase or decrease depending upon the credit ratings of the borrower. A credit rating is not a recommendation to buy, sell, or hold securities. It should be evaluated independently of any other rating. Ratings are subject to revision or withdrawal at any time by the
rating organization.
Collateral Postings Any adverse change in the Ameren Companies' credit ratings may reduce access to capital and trigger
additional collateral postings and prepayments. Such changes may also increase th e cost of borrowing and fuel, power, and natural gas supply, among other things, resulting in a negative impact on earnings. Cash collateral postings and prepayments made with external parties, including postings related to exchange-traded contracts at December 31, 2011, were $145 million, $11 million, $102 million and $1 million at Ameren, Ameren Missouri, Ameren Illinois and Genco, respectively. The amount of
cash collateral external co unterparties posted with Ameren was $6 million at December 31, 2011. Sub-investment-grade issuer or senior unsecured debt ratings (lower than "BBB-" or "Baa3") at December 31, 2011, could have resulted in Ameren, Ameren Missouri, Ameren Illinois or Genco being required to post additional collateral or other assurances for certain trade obligations amounting to $332 million, $86 million, $125 million, and
$58 million, respectively. Mood y'sS&PFitch Ameren:Issuer/corporate credit rating Baa3 BBB-BBBSenior unsecured debt Baa3 BB+BBBCommercial pape r P-3 A-3F2Ameren Missouri:Issuer/corporate credit rating Baa2 BBB-BBB+

OUTLOOK Ameren seeks to earn competitive returns on its investments in its businesses. Ameren Missouri and Ameren Illinois are seeking to improve their regulatory frameworks and cost recovery mechanisms. At the same time, Ameren's rate-regulated businesses are pursuing constructive regulatory outcomes within existing frameworks and are seeking to align their overall spending, both operating and capital, with economic conditions and cash flows provided by their regulators. Consequently, Ameren's rate-regulated businesses
expect to narrow the historic gap between allowed and earned returns on equity. Ameren's Merchant Generation segment maintains a fleet of competitive coal-fired and natural gas generating assets. Ameren's merchant generation strategy is to position itself as a low-cost provider and to benefit from an expected future recovery of power prices. Ameren intends to allocate its capital resources to those business opportunities, including electric and natural gas transmission, that offer the most attractive risk-adjusted return potential. Below are some key trends, events, and uncertainties that are reasonably likely to affect the Ameren
Companies' financial condition, results of operations, or liquidity as well as their ability to achieve strategic and financial objectives for 2012 and beyond. Rate-Regulated Operations Ameren's strategy for earning competitive returns on its rate-regulated investments involves meeting customer energy needs in an efficient fashion, working to enhance regulatory frameworks, making timely and well-supported rate filings, and aligning overall spending with those rate case outcomes, economic conditions and return opportunities. The IEIMA, enacted late in 2011, provides for a performance-based formula ratemaking framework for electric delivery utilities in Illinois. On January 3, 2012, Ameren Illinois elected to participate in this regulatory framework by making its in itial performance-based formula rate filin g with the ICC. We believe that our Table of Contentsparticipation in this framework will better enable Ameren Illinois to earn its allowed return on equity for its electric delivery service business. This is expected to give Ameren Illinois the earnings predictability to invest in modernizing its distribution system. During 2012, Ameren Illinois is required to make a one-time
$7.5 million nonrecoverable donation to the Illinois Science and Energy Innovation Trust. Additionally, Ameren Illinois is required to make an annual donation to that same trust and to fund customer assistance programs, both of which will total
approximatel y $2 million, in the a gg re g ate, in 2012. As they continue to experience cost recovery pressures, Ameren Missouri and Ameren Illinois expect to regularly seek electric and natural gas rate increases and timely cost recovery and tracking mechanisms from their regulators. These pressures include lower load growth from a weak economy, customer conservation efforts, and the impacts of energy efficiency programs, increased investments and expected future investments for environmental compliance, system reliability improvements, and new baseload capacity, including renewable requirements.
Increased investments also result in higher depreciation and financing co sts. Increased costs are also expected from rising employee benefit costs, higher property and income taxes, and higher insurance premiums as a result of insurance market conditions and loss experience, among other things.
Following recommendations from the NRC's task force on lessons learned from the 2011 reactor
accident in Japan, the NRC is expected to issue orders in 2012 requiring United States nuclear plants to enhance nuclear plant readiness to safely manage severe events. Such orders are expected to result in increased costs or investments. Ameren's rate-regulated businesses have procured rate increases. In January 2012, the ICC issued an order that authorized a $32 million increase in Ameren Illinois' annual natural gas delivery service revenues.
This request was based on a future test year of 2012, rather than a historical test year, in order to improve the ability to earn returns allowed by regulators. In 2011, Ameren Missouri received separate rate increases for its electric and natural gas businesses. In January 2011, the MoPSC approved a stipulation and agreement that authorized an increase in annual natural gas delivery revenues of $9 million. In July 2011, the MoPSC issued an order approving an increase in annual revenues for electric service of
$173 million. Depreciation for the Sioux scrubbers, previously deferred as a regulatory asset when placed in service in November 2010, will result in an increase
in annual expense of $21 million, beginning in August 2011. In addition, capitalization of interest was discontinued in July 2011. The MoPSC also issued an order, in April 2011, with respect to its review of Ameren Missouri's FAC for the period from March 1, 2009, to September 30, 2009. The order required Ameren Missouri to refund $18 million, including $1 million for interest, to customers related to earnings associated with certain long-term partial requirements sales that were made by Ameren Missouri due to the loss of Noranda's load caused by a severe ice storm in January 2009. Ameren Missouri has appealed this decision to the Cole County Circuit Court. The MoPSC is currently conducting its FAC review for periods after September 2009. It is possible that the MoPSC could order additional refunds of $25 million related to periods after September 2009, and this could result in a charge to earnings. Ameren Missouri filed a request with the MoPSC in July 2011 for an accounting authority order that would allow Ameren Missouri to recover fixed costs totaling $36 million that were not recovered as a result of the loss of load caused by the severe 200 9 ice storm for potential recovery in a future electric rate case. In January 2012, Ameren Missouri made its initial filing under the MEEIA. The MEEIA requires the MoPSC to ensure that a utility's financial incentives are aligned with helping customers use energy more efficiently, to provide timely cost recovery, and to provide earnings opportunities associated with cost-effective energy efficiency programs. Ameren Missouri's filing proposes a three-year plan that includes a portfolio of energy efficiency programs along with a cost-recovery mechanism. If the proposal is approved, beginning in January 2013, Ameren Missouri plans to invest $145 million over three years in the proposed energy efficiency programs. Ameren Missouri's second filing, made in February 2012, was a request to increase its annual revenues for electric service by $376 million, which includes recovery of the cost of the proposed energy efficiency programs included in the MEEIA filing. A MoPSC decision in Ameren Missouri's MEEIA filing is anticipated in the second quarter of 2012, while an electric rate order is expected in December 2012. Ameren and Ameren Missouri also are pursuing recovery from insurers, through litigation, for reimbursement of unpaid liability insurance claims for a December 2005 breach of the upper reservoir at Ameren Missouri's Taum Sauk pumped-storage hydroelectric energy center. Approximately 340 employees of Ameren Missouri and Ameren Services accepted voluntary separation offers and left the company as of December 31, 2011. As a result of the voluntary separations, Ameren and Ameren Missouri estimate an annual $20 million reduction in operations and maintenance expense be g innin g in 2012. Ameren Missouri's Callaway energy center completed a scheduled refueling and maintenance outage during the fourth quarter of 2011. Ameren Missouri's next scheduled refueling and maintenance outage is in the spring of 2013. During a scheduled outage, which occurs every 18 months, maintenance and purchased power costs increase, and the amount of excess power available for sale decreases, versus non-outa g e years. Ameren intends to allocate its capital to those 67 investment opportunities with the highest expected Table of ContentsMerchant Generation Operations risk-adjusted returns. Ameren believes that because of its strategic location in the country, electric transmission may provide it with such an opportunity. In December 2011, MISO approved three projects, which will be developed by ATXI or ATX. The first project, Illinois Rivers, involves building a 345-kilovolt line across the state of Illinois, from the Missouri
border to the Indiana border. Work on the first sections of this project will begin in 2012; the expected in-service date is 2016. The last section of this project is expected to be complet ed in 2019. The Spoon River project in northwest Illinois and the Mark Twain project in northeast Missouri are the other two projects approved by MISO in its current transmission expansion plan. These two projects are expected to be completed in 2018. The estimated total investment in these three projects is expected to be more than $1.2 billion. FERC, in its order issued in May 2011, approved transmission rate incentives for the Illinois Rivers project as well as for the Big Muddy project.
The Big Muddy project, located primarily in southern
Illinois, is currently being evaluated for inclusion in MISO's 2012 transmission expansion plan. During January 2012, the weather conditions in Ameren Missouri's and Ameren Illinois' service territories were unseasonably warm. Heating degree-days in Ameren's rate-regulated service territories were 14% lower than normal winter weather
conditions and 25% lower than weather conditions that occurred durin g Januar y 2011. For additional information regarding recent rate orders and related appeals, pending requests filed with state and federal regulatory commissions, the FAC prudence review and related appeal, and Taum Sauk matters, see Note 1 - Summary of Significant Accounting Policies, Note 2 - Rate and Regulatory Matters, and Note 15 - Commitments and
Contin gencies under Part II, Item 8, of this report. In this period of genera lly weak power prices, Ameren is focused on improving and reducing the volatility of, operating cash flows within its Merchant Generation
business so that cash flows from operations approximate required in vestments. Merchant Generation has reduced op erating costs and sought cost-efficient methods to comply with significant environmental requirements. Merchant Generation expects to continue to pursue these strategies while
positioning themselves for an expected future recovery in power prices and margins. As part of this strategy Genco closed its Meredosia and Hutsonville energy centers at the end of 2011, primarily because environmental investments expected to be required were not economical. The closures and the retention of these energy centers' emission allowances create flexibility to lower compliance costs at other Merchant Generation energy centers. In addition, the closure of the Hutsonville and Meredosia ener gy centers is not expected to have a material impact on Ameren's or Genco's future earnings. In 2011, nearly all of Merchant Generation's margin was generated from sales of output from five baseload energy centers (Newton, Joppa, Coffeen, E.D. Edwards, and Duck Creek). The Merchant Generation segment expects to have available generation from its coal-fired energy centers of 32.5 million megawatthours in 2012. However, based on currently expected power prices, the Merchant Generation segment expects to generate approximately 27 million (Genco - 20 million) megawatthours of power in 2012. See Note 15 - Commitments and Contingencies under Part II, Item 8, of this report for further discussion of environmental matters and compliance plans. Power prices in the Midwest affect the amount of revenues and cash flows Merchant Generation and Genco can generate by ma rketing power into the wholesale and retail markets. Market prices for power have decreased over the past three years. During 2012, the market price for power for delivery in the
current year has declined be low 2011 leve ls because of factors such as declining natural gas prices and the stay of the CSAPR. From December 31, 2011, through January 31, 2012, the market price for power at the Indiana Hub decreased by 12%. Ameren's Merchant Generation segment and Genco will be adversely impacted by the declining market price of power for any unhedged generation. Merchant Generation and Genco are currently evaluating this recent price decline and the impact of the stay of the CSAPR, and the potential impact these events may have on their operating and capital investment plans.
In 2012, Genco decelerated the construction of two scrubbers at its Newton energy center, and AERG removed from its five-year capital expenditures forecast previously planned precipitator upgrades at its E.D. Edwards energy center. Based on current environmental rules and regulations, if Merchant Generation and Genco do not complete these environmental upgrades by the beginning of 2015, Merchant Generation and Genco may need to reduce generation output at their energy centers to reduce emissions. Merchant Generation and Genco will also evaluate whether the decline in the market price for power in the first quarter of 2012, and any changes to operating and capital plans, is indicative that the carrying value of its energy centers may not be recoverable. A failure to achieve forecasted operating results and cash flows, an unfavorable change in forecasted operating results and cash flows, or a reduction in the expected useful lives of Merchant Generation's energy centers could result in the recognition of long-lived asset impairment charges. Merchant Generation's energy centers without pollution control equipment are most exposed to declining power prices as compliance options for environmental laws and regulations could become prohibitivel y expensive. To reduce cash flow volatility, Marketing Company, through a mix of physical and financial sales 68 contracts, targets to hedge Merchant Generation's expected output by 80% to 90% for the following year, 50% to Table of ContentsLiquidity and Capital Resources 70% for two years out, and 30% to 50% for three years out. As of January 31, 2012, Marketing Company had hedged approximately 25 million megawatthours of Merchant Generation's expected generation for 2012, at an average price of $44 per megawatthour. For 2013, Marketing Company had hedged approximately 14 million megawatthours of
Merchant Generation's forecast ed generation sales at an average price of $40 per megawatthour. For 2014, Marketing Company had hedged approximately 7 million megawatthours of Merchant Generation's forecasted generation sales at an average price of
$44 per megawatthour. Any unhedged forecasted generation will be exposed to market prices at the time of sale. As a result, any new physical or financial power sales may be at price levels lower than previously experienced and lower than the value of existin g hed ged sales. Merchant Generation is als o supporting development of an energy capacity market within MISO, which is expected to support longer-term investment. FERC is expected to issue an order on MISO's proposal to
establish a capacity market within the RTO. The MISO proposal calls for the first annual capacity auction to be held in April 2013 for the June 2013 to May 2014 planning year. To further reduce cash flow volatility, Merchant Generation seeks to hedge fuel costs consistent with power sales. As of January 31, 2012, for 2012 Merchant Generation had hedged fuel costs for approximately 25 million megawatthours of coal and up to 28 million megawatthours of base transportation at about $24 per megawatthour. For 2013, Merchant Generation had he dged fuel costs for approximately 12 million megawatthours of coal and up to 27 million megawatthours of base transportation at about $25.50 per megawatthour. For 2014, Merchant Generation had hedged fuel costs for approximately 5 million megawatthours of coal and up to 21 million megawatthours of base transportation at about $25.50 per megawatthour. In 2012, Genco and the Merchant Generation segment are targeting a reduction in coal inventories. See Item 7A - Quantitative and Qualitative Disclosures About Market Risk of this report for additional information about the percentage of fuel and transportation requirements that are price-hed g ed for 2012 throu gh 2016. The Ameren Companies seek to maintain access to the capital markets at commercially attractive rates in order to fund their businesses. The enhancement of regulatory frameworks and returns is expected to improve cash flows, credit metrics, and related access to capital for Ameren's rate-re g ulated businesses. Genco and the Merchant Ge neration segment seek to fund their operations internally and therefore seek not to rely on financing from Ameren or external, third-party sources. Genco and the Merchant Generation se gment will continue to seek to defer capital and operating expenses, sell certain assets, and take other actions as necessary to fund their operations internally while maintaining safe and reliable operations. Under its indenture, Genco may not borrow additional funds from external, third-party sources if its interest coverage ratio is less than a specified minimum or its leverage ratio is greater than a specified maximum. Based on projections as of December 31, 2011, of Genco's operating results and cash flows, we expect that, by the end of the first quarter of 2013, Genco's interest coverage ratio will be less than the minimum ratio required for the company to borrow additional funds from external, third-party sources. Genco's indenture does not restrict intercompany borrowings from Ameren's non-state-regulated subsidiary money pool. However, borrowings from the money pool are subject to Ameren's control, and if a Genco intercompany financing need were to arise, borrowings from the non-state-regulated subsidiary money pool by Genco would be dependent on cons ideration by Ameren of the facts and circumstances existin g at that time. The Ameren Companies have also entered into multiyear credit facility agreements that cumulatively provide $2.1 billion of credit through September 10, 2013. We believe that our liquidity is adequate given our expected operating cash flows, capital expenditures, and related financing plans. However, there can be no assurance that significant changes in economic conditions, disruptions in the capital and credit markets, or other unforeseen events will not materially affect our ability to execute our expected
operatin g, capital or financin g plans. In September 2012, $173 million of Ameren Missouri's 5.25% senior secured notes mature. As of December 31, 2011, Ameren had approximately $390 million in federal income tax net operating loss carryforwards (Ameren Missouri - $140 million, Ameren Illinois - $90 million, Genco - $20 million) and $72 million in federal income tax credit
carryforwards (Ameren Missouri - $11 million, Ameren Illinois - $- million, Genco - $1 million). These carryforwards are expected to satisfy income tax liabilities through the end of 2013 (Ameren Missouri - 2012, Ameren Illinois - 2012, Genco - 2013).Between 2012 and 2021, Ameren currently expects to invest between $1.8 billion to $2.2 billion to retrofit its coal-fired energy centers with pollution control equipment in compliance with environmental laws and regulations. Any pollution control investments will result in decreased energy center availability during construction and signif icantly higher ongoing operating expenses. Any polluti on control investments at Ameren Missouri are expected to be recoverable from ratepayers, subject to prudence reviews.
Regulatory lag may materially affect the timing of such recovery and returns on the investments, and therefore affect our cash flows and related financing needs. The recoverability of amounts expended in our Merchant Generation segment will depend on whether 69 market prices for power adjust as a result of market conditions reflecting increased environmental costs for coal-fired generators.
Table of ContentsREGULATORY MATTERS See Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report. ACCOUNTING MATTERS Critical Accounting Estimates Preparation of the financial statements and related disclosures in compliance with GAAP requires the application of appropriate technical accounting rules and guidance, as well as the use of estimates. These estimates involve judgments regarding many factors which in and of themselves could materially affect the financial statements and disclosures. We have outlined below the critical accounting estimates that we believe are most difficult, subjective, or complex. Any change in the assumptions or judgments applied in determining the following matters, among others, could have a material impact on future financial results. Regulatory Mechanisms and Cost Recovery Basis for Judgment We determine which costs are recoverable by consulting previous rulings by state regulatory authorities in jurisdictions where we operate and any other factors that may indicate whether cost recovery is probable. If facts and circumstances lead us to conclude that a recorded regulatory asset is no longer probable of recovery or that plant assets are probable of disallowance, we record a charge to earnings, which could be material. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report for quantification of these assets for each of the Ameren Companies, excluding Genco.
Unbilled Revenue Basis for Judgment We base our estimate of unbilled revenue each period on the volume of energy delivered, as valued by a model of billing In October 2011, Ameren
's board of directors declared a fourth quarter dividend of 40 cents per common share, a 3.9% increase from the prior quarterly dividend of 38.5 cents per share, resulting in an annualized equivalent dividend of $1.60 per share. Based on the shares outstanding at the end of
October 2011, on an annual basis, the dividend increase will result in additional dividends of $15 million.In February 2012, Ameren completed the asset sale of its Medina Valley energy center's net property and
plant for cash proceeds of $16 million. The loss of margin contributed by Medina Valley is not expected to
materially impact Amere n's 2012 results of operations. Ameren and Genco are currently exploring opportunities to make the Meredosia energy center available for those parties interested in repowering one of its units to create an oxy-fuel combustion coal-fired energy center designed for permanent CO capture and stora g e.2Accounting Estimate Uncertainties Affecting Application Ameren, Ameren Missouri and Ameren Illinois defer

This figure is then adjusted for the modeled impact of seasonal and weather variations based on historical results. See the balance sheets for each of the Ameren Companies, excluding Genco, under Part II, Item 8, of this report for unbilled revenue amounts. 70 Table of ContentsDerivative Financial Instruments Basis for Judgment We evaluate contracts to determine whether they contain derivatives. Determining whether or not a contract qualifies as a derivative under authoritative accounting guidance requires us to exercise significant judgment in interpreting the definition of a derivative and applying that definition. Authoritative accounting guidance regarding derivative instruments requires that all contracts considered to be derivative instruments be recorded on the balance sheet at their fair values, unless the NPNS exception applies. We determine whether to exclude the fair value of certain derivatives from valuation under the NPNS provisions of authoritative accounting guidance after assessing our intent and ability to physically deliver commodities purchased and sold. Further, our forecasted purchases and sales also support our designation of some fair valued derivative instruments as cash flow hedges. Fair value of our derivatives is measured in accordance with authoritative accounting guidance, which provides a fair value hierarchy that prioritizes inputs to valuation techniques. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. When we do not have observable inputs, we use certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risks inherent in the inputs to the valuation. Our valuations also reflect our own assessment of counterparty default risk, guided by the best internal and external information available. If we were required to discontinue our use of the NPNS exception or cash flow hedge treatment for some of our contracts, the impact of changes in fair value for the applicable contracts could be material to our earnings and financial position. Valuation of Long-Lived Assets and Asset Retirement Obligations Basis for Judgment Whenever events or changes in circumstances indicate a valuation may have changed, we use various methodologies that we believe market participants would use to determine valuations and discounted, undiscounted, and probabilistic discounted cash flow models with multiple operating scenarios. The identification of asset retirement obligations is conducted through the review of legal documents and interviews. See Note 1 - Summary of Significant Accounting Policies under Part II, Item 8, of this report for quantification of our asset retirement obligations. See Note 17 Goodwill, Impairment and Other Charges under Part II, Item 8, of this report for additional information of our long-lived asset impairment evaluation and charges recorded. 71 Accounting Estimate Uncertainties Affecting Application We account for derivative financial instruments and measure their fair value in accordance with authoritative accounting guidance. The identification and
classification of a derivative and the fair value of such derivative must be determined. See Commodity Price Risk and Fair Value of Contracts in Quantitative and Qualitative Disclosures About Market Risk under Part II, Item 7A, Note 7 - Derivative Financial Instruments and Note 8 - Fair Value Measurements under Part II, Item 8, of this report.

We also review for the existence of asset retirement obligations. If an asset retireme nt obligation is identified, we determine its fair value and subsequent ly reassess and adjust the obligation, as necessary.

See Note 11 - Retirement Benefits under Part II, Item 8, of this report for sensitivity of Ameren's benefit plans to potential changes in these assumptions.
Accounting for Contingencies Basis for Judgment The determination of a loss contingency requires significant judgment as to the expected outcome of each contingency in future periods. In making the determination as to the amount of potential loss and the probability of loss, we consider all available evidence including the expected outcome of potential litigation. If no estimate is better than another within our range of estimates, we record our best estimate of a loss or the minimum value of our estimated range of outcomes. As additional information becomes available, we reassess the potential liability related to the contingency and revise our estimates. In our evaluation of legal matters, management consults with legal counsel and relies on analysis of relevant case law and legal precedents. See Note 2 - Rate and Regulatory Matters, Note 10 - Callaway Energy Center, and Note 15 - Commitments and Contingencies under Part II, Item 8, of this report for information on the Ameren Companies' contingencies. Impact of Future Accounting Pronouncements See Note 1 - Summary of Significant Accounting Policies under Part II, Item 8, of this report. Accounting Estimate Uncertainties Affecting Application Based on actuarial calculations, we accrue costs of providing future employee benefits in accordance with authoritative accounting guidance regarding benefit plans. See Note 11 - Retirement Benefits under Part II, Item 8, of this report. Future rate of return on pension and other plan assets Interest rates used in valuin g benefit obli g ations Health care cost trend rates Timing of employee retirements and mortality assumptions Ability to recover certain benefit plan costs from our ratepayers Changing market conditions that may affect investment and interest rate environments Impacts of the health care reform legislation enacted in 2010 We make judgments and estimates in recording liabilities for claims, litigation, environmental remediation, the actions of various regulatory agencies, or other matters that occur in the normal course of business. We record a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. A gain contingency is not recorded until realized or realizable. Estimating financial impact of events Estimating likelihood of outcomes Regulatory and political environments and requirements Outcome of legal proceedings, settlements or other factors EFFECTS OF INFLATION AND CHANGING PRICES Ameren's rates for retail electric and natural gas utility service are regulated by the MoPSC and the ICC.
Nonretail electric rates are r egulated by FERC. Rate regulation is generally based on the recovery of historical or projected costs. As a result, revenue increases could lag behind changing prices. Ameren Illinois has recently elected to participate in the performance-based formula ratemaking process for determining retail rates for its electric delivery service business established by the IEIMA. Ameren Illinois' participation in this formula ratemaking process will terminate if the average average residential rate includes generation service, which is outside of Ameren Illinois' control as it is required to purchase all of its power through procurement processes administered by the IPA. The cost of procured power can be affected by inflation. Within that formula, the monthly average yields of 30-year United States Treasury bonds are the basis for Ameren Illinois' return on equity. Therefore, pending ICC approval of Ameren Illinois' initial filing under the IEIMA, which is expected to occur in October 2012, there will be a direct correlation
between the yield of United States Treasury bonds, which are affected by inflation, and the earnings of Ameren 72residential rate increases by more than 2.5% annually from June 2011 through May 2014. The Illinois' electric distribution business. Inflation affects our operations, earnings, stockholders' equity, and financial performance.
Table of Contents ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. The current replacement cost of our utility plant substantially exceeds our recorded historical cost. Under existing regulatory practice, only the historical cost of plant is recoverable from customers. As a result, cash flows designed to provide recovery of historical costs through depreciation might not be adequate to replace the plant in future years. Ameren's Merchant Generation business does not have regulated recovery mechanisms and is therefore dependent on market prices for power to reflect rising costs. Ameren Missouri recovers the cost of fuel for electric generation and the cost of purchased power by adjusting rates as allowed through the FAC. Ameren Illinois recovers power supply costs from electric customers by adjusting rates through a rider mechanism to accommodate changes in power prices. Ameren Missouri and Ameren Illinois are affected by changes in the cost of electric transmission services.
FERC regulates the rates charged and the terms and conditions for electric transmission services. Each RTO separately files regional transmission tariff rates for approval by FERC. All members within that RTO are then subjected to those rates. Because they are members of MISO, Ameren Missouri's and Ameren Illinois' transmission rates are calculated in accordance with MISO's rate formula. The transmission rate, updated in June of each year, is based on FERC filings for the
previous year. This rate is charged directly to wholesale customers. Ameren Illinois also charges this rate directly to alternative retail electric suppliers. For Illinois' retail customers who have not chosen an
alternative retail electric supplier, the transmission rate is collected through a rider mechanism. This rate is not directly charged to Missouri retail customers because the MoPSC includes transmission-related costs in setting bundled retail rates in Missouri. In our Missouri and Illinois retail natural gas utility j urisdictions, changes in gas costs are generally reflected in billings to gas customers through PGA clauses. Ameren, Ameren Missouri and Genco are affected by changes in market prices for natural gas to the extent that they must purchase natural gas to run CTs. These companies have stru ctured various supply agreements to maintain access to multiple natural gas pools and supply basins, and to minimize the impact to their financial statements. Ameren Missouri' s exposure to changes in market prices of natural gas is mitigated by its ability to recover increasing costs via a FAC. See Quantitative and Qualitative Disclosures About Market Risk - Commodity Price Risk under Part II, Item 7A, below for additional
information.See Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report for additional information on the cost recovery mechanisms. Market risk is the risk of changes in value of a physical asset or a financial instrument, derivative or nonderivative, caused by fluctuations in market variables such as interest rates, commodity prices, and equity security prices. A derivative is a contract whose value is dependent on, or derived from, the value of some underlying asset or index. The following discussion of our risk management activities includes forward-looking statements that involve risks and uncertainties. Actual results could differ materially from those projected in the forward-looking statements. We handle market risks in accordance with established policies, which may include entering into various derivative transactions. In the normal course of business, we also face risks that are either nonfinancial or nonquantifiable. Such risks, principally business, legal, and operational risks, are not part of the
following discussion. Our risk management objective is to optimize our physical generating assets and to pursue market opportunities within prudent risk parameters. Our risk management policies are set by a risk management
steering committee, which is composed of senior-level
Ameren officers. Interest Rate Risk We are exposed to market risk through changes in We manage our interest rate exposure by controlling the amount of debt instruments we have within our total capitalization portfolio and by monitoring the effects of market changes in interest rates. For defined pension and postretirement benefit plans, we control the duration and the portfolio mix of our plan assets. The following table presents the estimated increase in our annual interest expense and decrease in net income if interest rates were to increase by 1% on variable-rate debt outstanding at December 31, 2011: The estimated changes above do not consider the potential reduced overall economic activity that would
exist fixed-rate debt; auction-rate lon g-term debt; and defined pension and postretirement benefit plans. Interest ExpenseNet Income Ameren$ 4 $ (2)

In the event of a significant change in interest rates, management would probably act to mitigate further exposure to this market risk. However, due to the uncertainty of the specific actions that might be taken and their possible effects, this sensitivity analysis assumes no change in our financial structure.
Credit Risk Credit risk represents the loss that would be recognized if counterparties fail to perform as contracted. Exchange-traded contracts are supported by the financial and credit quality of the clearing members of the respective exchanges and have nominal credit risk. In all other transactions, we are exposed to credit risk in the event of nonperformance by the counterparties to the transaction. See Note 7 - Derivative Financial Instruments under Part II, Item 8, of this report for information on the potential loss on counterparty exposure as of December 31, 2011. Our rate-regulated revenues are primarily derived from sales or delivery of electricity and natural gas to
customers in Missouri and Illinois. Our physical and financial instruments are subject to credit risk consisting of trade accounts receivables and executory contracts with market risk exposures. The risk associated with trade receivables is mitigated by the large number of customers in a broad range of industry groups who make up our customer base. At December 31, 2011, no nonaffiliated customer represented more than 10%, in the aggregate, of our accounts receivable at Ameren Illinois. Noranda, Ameren Missouri's largest nonaffiliated electric customer, has appealed certain aspects of the 2009 and 2010 rate orders issued by the MoPSC. Noranda has paid into court registries amounts that represent more than 10%, in the
aggregate, of Ameren Missouri's accounts receivable at December 31, 2011. In Nove mber 2011, the Missouri Court of Appeals issued a ruling that upheld the MoPSC's January 2009 electric rate order. Therefore, Ameren Missouri expects to receive all of the funds held in the Stoddard County Circuit Court's registry relating to the 2009 rate order, which totaled $20 million as of December 31, 2011, during the first quarter of 2012. The funds related to the 2010 appeal will remain in the Cole County Circuit Court's registry pending resolution, which is expected in 2012. See Note 2 - Rate and Regulatory Matters under Part II, Item 8, of this report for additional information. The risk associated with Ameren Illinois' electric and natural gas trade receivables is also mitigated by a rate adjustment mechanism that allows Ameren Illinois to recover the difference between its actual bad debt expense under GAAP and the bad debt expense included in its base rates. Ameren Missouri and Ameren Illinois continue to monitor the impact of increasing rates on customer collections. Ameren Missouri and Ameren Illinois make adjustments to their allowance for doubtful accounts as deemed necessary to ensure that such allowances are adequate to cover estimated uncollectible customer account balances.Ameren, Ameren Missouri, Ameren Illinois and Genco may have credit exposure associated with off-system or wholesale purchase and sale activity with nonaffiliated companies. At December 31, 2011, Ameren's, Ameren Missouri's, Ameren Illinois' and Genco's combined credit exposure to nonaffiliated trading counterparties, excluding coal suppliers, deemed below investment grade either through external or internal credit evaluations, was
$48 million, net of collateral (2010 - $204 million). Almost all of the $48 million exposure relates to Ameren Illinois' long-term purchase power and renewable energy credit contracts. These contracts were procured through the IPA and are passed through directly to Ameren Illinois customers. At December 31, 2011, the combined credit exposures to nonaffiliated coal suppliers, deemed below investment grade either through external or internal credit evaluations, net of collateral, were $35 million, $33 million and $2 million at Ameren, Ameren Missouri and Genco, respectively. (2010- $ 19 million, $8 million, $10 million, respectively). We establish credit limits for these counterparties and monitor the appropriateness of these limits on an ongoing basis through a credit risk management program.
Monitoring involves daily exposure reporting to senior management, master trading and netting agreements, and credit support, such as letters of credit and parental guarantees. We also analyze each counterparty's
financial condition before we enter into sales, forwards, swaps, futures, or option contracts. We estimate our credit exposure to MISO associated with the MISO Energy and Operating Reserves Market to be $29 million
at December 31, 2011 (2010 - $53 million). Equity Price Risk Our costs for providing defined benefit retirement and postretirement benefit plans are dependent upon a number of factors, including the rate of return on plan assets. Ameren manages plan assets in accordance with the "prudent investor" guidelines contained in ERISA. Ameren's goal is to ensure that sufficient funds are available to provide the benefits at the time they are payable while also to maximizing total return on plan assets and minimizing expense volatility consistent with its tolerance for risk. Ameren delegates investment management to specialists. Where appropriate, Ameren provides the investment manager with guidelines that specify allowable and proh ibited investment types. Ameren regularly monitors manager performance and compliance with investment guidelines. The expected return on plan assets is based on historical and projected rates of return for current and planned asset classes in the investment portfolio.
Projected rates of return for each asset class were estimated after an analysis of historical experience, future expectations, and the volatility of the various asset classes. After considering the target asset allocation for each asset class, we adjusted the overall expected rate of return for the portfolio for historical and expected experience of active portfolio management results compared with benchmark returns, and for the effect of expenses paid from plan assets.
Table of Contents75 In future years, the costs of such plans will be reflected in net income, OCI, or regulatory assets. Contributions to the plans could increase materially, if we do not achieve pension and postretirement asset portfolio investment returns equal to or in excess of our 2012 assumed return on plan assets of 7.75% and 7.50%, respectively. Ameren Missouri also maintains a trust fund, as required by the NRC and Missouri law, to fund certain costs of nuclear plant decommissioning. As of December 31, 2011, this fund was invested primarily in domestic equity securities (66%) and debt securities (34%). It totaled $357 million (2010 - $337 million). By
maintaining a portfolio that includes long-term equity investments, Ameren Missouri seeks to maximize the returns to be used to fund nuclear decommissioning costs within acceptable parameters of risk. However, the equity securities included in the portfolio are exposed to price fluctuations in equity markets. The debt securities are exposed to changes in interest rates. Ameren Missouri
actively monitors the po rtfolio by benchmarking the performance of its investments against certain indices and by maintaining and periodically reviewing established
target allocation percentages of the assets of the trust to various investment options. Ameren Missouri's exposure to equity price market risk is in large part mitigated, because Ameren Missouri is currently allowed to recover its decommissioning costs, which would include unfavorable investment results, through electric rates. Additionally, Ameren has company-owned life insurance contracts that are used to support Ameren's deferred compensation plans. These life insurance contracts include equity and debt investments that are
exposed to price fluctuations in equity markets and to changes in interest rates. Commodity Price Risk We are exposed to changes in market prices for power, emission allowances, coal, transportation diesel, natural gas and uranium. Ameren's, Ameren Missouri's and Genco's risks of changes in prices for power sales are partially hedged through sales agreements. Merchant Generation also seeks to sell power forwar d to wholesale, municipal, and industrial customers to limit exposure to changing prices.
We also attempt to mitigate financial risks through risk management programs and policies, which include forward-hedging programs, and through the use of derivative financial instruments (primarily forward contracts, futures contracts, option contracts, and financial swap contracts). However, a portion of the generation capacity of Ameren, Ameren Missouri and Genco is not contracted through physical or financial hedge arrangements and is therefore exposed to volatility in market prices. The following table shows how our earnings might decrease if power prices were to decrease by 1% on unhedged economic generation for 2012 through 2015:
Ameren's forward-hedging power programs include the use of derivative fin ancial swap contracts. These swap contracts financially settle a fixed price against a floating price. The floating price is typically the realized, or settled, price at a liquid regional hub at some forward period of time. Ameren controls the use of derivative financial swap contracts with volumetric and correlation limits that are intended to mitigate any material adverse financial impact. Historically, Ameren has used swaps that settled against the Cinergy Hub MISO locational marginal pricing. This hub had traditionally been the most liquid location, with a strong correlation to the pricing that was realized at our generating locations. As of December 31, 2011, MISO stopped publishing Cinergy Hub pricing. As a result, Ameren will now use the Indiana Hub and other hubs as necessary for financial hedging. Ameren does not expect any material adverse financial impact to the outcomes of its forward-hedging programs as a result of this change. Ameren will continue to pursue the best available options to fix pricing for the output of its generating units. Ameren also uses its portfolio management and trading capabilities both to manage risk and to deploy risk capital to generate additional returns. Due to our physical presence in the market, we are able to identify and pursue opportunities, which can generate additional returns through portfolio management and trading activities. All of this activity is performed within a controlled risk management process. We establish value at risk (VaR) and stop-loss limits that are intended to
prevent any mate rial negative financial impact. We manage risks associated with changing prices of fuel for generation with techniques similar to those we use to manage risks associated with changing market prices
for electricity. Merchant Generation does not have the ability to pass higher fuel costs through to its customers for electric operations with the exception of an immaterial percentage of the output that has been contracted with a fuel cost pass-through. Ameren Missouri has a FAC that allows Ameren Missouri to recover, through customer rates, 95%
of changes in fuel and purchased power costs, net of off-system revenues, including MISO costs and revenues, more or less than the amount set in base rates, without a traditional rate proceeding. Ameren Missouri remains exposed to the remaining 5%. Net Income Ameren$ (13)

Table of ContentsAmeren, Ameren Missouri and Genco have entered into coal contracts with various suppliers to purchase coal to manage their exposure to fuel prices. The coal hedging strategy is intended to secure a reliable coal supply while reducing exposure to commodity price volatility. Additionally, the type of coal burned is part of Ameren Missouri's environmental compliance strategy. Ameren Missouri has a multiyear agreement to purchase ultra-low-sulfur coal through 2017 to comply with the CSAPR and other environmental regulations. The coal contract is with a single supplier. Disruptions of the deliveries of that ultra-low-sulfur coal from the supplier could compromise Ameren Missouri's ability to operate in compliance with emission standards. Other sources of ultra-low-sulfur coal are limited and the construction of pollution control equipment requires significant lead time to become
operational. Should a temporary disruption of ultra-low-sulfur coal deliveries occur and its existing inventory of ultra-low-sulfur coal becomes fully depleted, and other
sources of ultra-low-sulfur coal are not available, Ameren Missouri would use its existing emission allowances or purchase emission allowances in order to achieve compliance with environmental regulations. Genco purchases coal based on expected power sales, generally through bid procedures. Therefore, Genco's forward coal requirements are dependent on the volume of power sales that have been contracted. Transportation costs for coal and natural gas can be a significant portion of fuel costs. Ameren, Ameren Missouri
and Genco typically hedge coal transportation forward to provide supply certainty and to mitigate transportation price volatility. Natural gas transportationexpenses for Ameren's gas distribution utility companies and for the gas-fired generation units of Ameren, Ameren Missouri and Genco are regulated by FERC through approved tariffs governing the rates, terms, and conditions of transportation and storage services. Certain firm transportation and storage capacity agreements held by the Ameren Companies include rights to extend the term of contracts. Depending on our competitive position, we
are able in some instances to negotiate discounts to these tariff rates for our requirements.
In addition, coal transportation costs are sensitive to the price of diesel fuel as a result of rail freight fuel surcharges. We use forward fuel oil contracts (both for heating and crude oil) to mitigate this market price risk as changes in these products are highly correlated to changes in diesel markets. If diesel fuel costs were to increase or decrease by $0.25 a gallon, Ameren's fuel expense could increase or decrease by $14 million annually (Ameren Missouri - $8 million, Genco - $5 million). As of December 31, 2011, Ameren had a price cap for approximately 87% of expected fuel surcharges in 2012. In the event of a significant change in coal prices, Ameren, Ameren Missouri and Genco would probably take actions to further mitigate their exposure to this market risk. However, due to the uncertainty of the specific actions that would be taken and their possible effects, this sensitivity analysis assumes no change in our financial structure or fuel sources. With regard to exposure for commodity price risk for nuclear fuel, Ameren Missouri has fixed-priced, base-
price-with-escalation, and market-priced agreements. It uses inventories to provide some price hedge to fulfill its Callaway energy center's needs for uranium, conversion, and enrichment. There is no fuel reloading or planned maintenance outage scheduled for 2012 and 2015. Ameren Missouri has price hedges for approximately 74% of its 2013 to 2016 nuclear fuel requirements. Nuclear fuel market prices remain subject to an unpredictable supply and demand environment. Ameren Missouri has continued to follow a strategy of managing its inventory of nuclear fuel as an inherent price hedge.
New long-term uranium contracts are almost exclusively market-price-related with an escalating price floor. New long-term enrichment contracts usually have a base-price-with-escalation price mechanism, and may also have either a market-price-related component or market-based price re-benchmarking. Ameren Missouri expects to enter into additional contracts from time to time in order to supply nuclear fuel during the expected life of the Callaway energy center, at prices that cannot now be accurately predicted. Unlike the electricity and natural gas markets, nuclear fuel markets have somewhat limited financial instruments available for price hedging, so most hedging is done through inventories and forward contracts, if they are available. The electric generating operations for Ameren, Ameren Missouri and Genco are exposed to changes in market prices for natural gas used to run CTs. The natural gas procurement strategy is designed to ensure reliable and immediate delivery of natural gas while minimizing costs. We optimize transportation and storage options and price risk by structuring supply agreements to maintain access to multiple gas pools and supply basins. Through the market allocation and auction process, Ameren and Ameren Missouri have been granted FTRs associated with the MISO Energy and Operating Reserves Market. In addition, Marketing Company has acquired FTRs for its participation in the PJM-Northern Illinois and MISO market. The FTRs are intended to mitigate electric transmission congestion charges related to the physical constraints of the transmission system. Depending on the congestion, FTRs could result in either charges or credits. Complex grid modeling tools are used to determine which FTRs to nominate in the FTR allocation process. There is a risk of incorrectly modeling the amount of FTRs needed, and there is the potential that the FTRs could be ineffective in mitigating transmission congestion charges. With regard to Ameren Missouri's and Ameren Illinois' electric and natural gas distribution businesses, exposure to changing market prices is in large part mitigated by the fact that there are cost recovery mechanisms in place.
These cost recovery mechanisms allow Ameren Missouri and Ameren Illinois to pass on to retail customers
prudently Table of ContentsThe following table presents, as of December 31, 2011, the percentages of the projected required s upply of coal and coal transportation for our coal-fired energy centers, nuclear fuel for Ameren Missouri's Callaway energy center, natural gas for our CTs and retail distribution, as appropriate, and purchased power needs of Ameren Illinois, which does not own generation, that are price-hedged over the period 2012 through 2016. The projected required supply of these commodities could be significantly affected by changes in our assumptions for such matters as customer demand for our electric generation and our electric and natural gas distribution services, gene ration output, and inventory levels, among other matters.The following table shows how our total fuel expense might increase and how our net income might decrease if coal and coal transportation costs were to increase by 1% on any requirements not currently covered by fixed-price contracts for the five-year period 2012 through 2016. With regard to our exposure for commodity price risk for construction and maintenance activities, Ameren is exposed to changes in market prices for metal commodities and to labor availability. See Supply for Electric Power under Part I, Item 1, of this report for the percentages of our historical needs satisfied by coal, nuclear power, natural gas, hydroelectric power, and oil.

Table of ContentsFair Value of Contracts Most of our commodity contracts that meet the definition of derivatives qualify for treatment as NPNS. We use derivatives principally to manage the risk of changes in market prices for natural gas, coal, diesel, power, and uranium. The following table presents the favorable (unfavorable) changes in the fair value of all derivative contracts marked-to-market during the year ended December 31, 2011. We use various methods to determine the fair value of our contracts. In accordance authoritative accounting guidance for fair value with hierarchy levels, the sources we used to determine the fair value of these contracts were active quotes (Level 1), inputs corroborated by market data (Level 2), and other modeling and valuation methods that are not corroborated by market data (Level 3). See Note 8 - Fair Value Measurements under Part II, Item 8, of this report for further information regarding the methods used to determine the fair value of these contracts.

Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on
criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financ ial reporting, included in Manag ement's Report on Internal Control over Fi nancial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial stat ements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over fi nancial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with general lyaccepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authoriza tions of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

It supplies electric and natural gas service to a 24,000-square-mile area in central and eastern Missouri. This area has an estimated
population of 2.9 million and includes the Greater St.
Louis area. Ameren Missouri supplies electric service to 1.2 million customers and natural gas service to
127,000 customers. Ameren Illinois Company, or Ameren Illinois, operates a rate-regulated electric and natural gas transmission and distribution business in Illinois. Ameren Illinois was created by the merger of CILCO and IP with and into CIPS. CIPS was incorporated in Illinois in 1923 and is successor to a number of companies, the
oldest of which was organized in 1902. Ameren Illinois supplies electric and natural gas utility service to portions of central and southern Illinois having an estimated population of 3.1 million in an area of 40,000 square miles. Ameren Illinois supplies electric service to 1.2 million customers and natural gas service to 809,000 customers. AER consists of non-rate-regulated operations, including Genco, AERG, Marketing Company and Medina Valley. The Medina Valley energy center was sold in Februar y 2012. Genco operates a merchant Ameren has various other subsidiaries responsible for activities such as the provision of shared services. On October 1, 2010, Ameren, CIPS, CILCO, IP, AERG and AER completed a two-step corporate internal reorganization. The first step of the reorganization was the Ameren Illinois Merger. Upon consummation of the Ameren Illinois Merger, the separate legal existence of CILCO and IP ended. The second step of the reorganization involved the distribution of AERG stock from Ameren Illinois to Ameren and the subsequent contribution by Ameren of the AERG stock to AER. The Ameren Illinois Merger and the distribution of AERG stock were accounted for as transactions between entities under common control. In accordance with authoritative
accounting guidance, assets and liabilities transferred between entities under common control were accounted for at the historical cost basis of the common parent, Ameren, as if the transfer had occurred at the beginning of the earliest reporting period presented. Ameren's historical cost basis in Ameren Illinois included purchase accounting adjustments related to Ameren's acquisition of CILCORP in 2003. Ameren Illinois accounted for the AERG distribution as a spinoff. Ameren Illinois transferred AERG to Ameren based on AERG's carrying value.
Ameren Illinois has segregated AERG's operating results and cash flows and presented them separately as discontinued operations in its consolidated statement of income and consolidated statement of cash flows, respectively, for all periods presented prior to October 1, 2010, in this report. For Ameren's financial statements, AERG's results of operations remain classified as continuing operations. See Note 16 - Corporate Reorganization and Discontinued Operations for additional information. Effective January 1, 2010, as part of an internal reorganization, AER transferred its 80% stock ownership interest in EEI to Genco through a capital contribution. The transfer of EEI to Genco was accounted for as a transaction between entities under common control, whereby Genco accounted for the transfer at the historical carrying value of the parent (Ameren) as if the transfer had occurred at the beginning of the earliest reporting period presented. Ameren's historical cost basis in EEI included purchase accounting adjustments relating to Ameren's acquisition of an additional 20% ownership interest in EEI in 2004. This transfer required Genco's prior-period financial statements to be retrospectively combined for all periods presented. Consequently, Genco's prior-period consolidated financial statements reflect EEI as if it had been a subsidiary of Genco. Ameren and Genco consolidate EEI for financial reporting electric generation business in Illinois and holds an 80% ownership interest in EEI, which it consolidates for financial reporting purposes. Genco was incorporated in Illinois in March 2000. Genco's coal and natural gas electric generating facilities are expected to have capacity of 3,095 and 1,348 megawatts, respectively, at the time of the 2012 peak summer electrical demand.

Table of ContentsMaterials and Supplies Materials and supplies are recorded at the lower of cost or market. Cost is determined using the average-cost method.
Materials and supplies are capitalized as inventory when purchased and then expensed or capitalized as plant assets when installed, as appropriate. The following table presents a breakdown of materials and supplies for each of the Ameren Companies at December 31, 2011, and 2010: 98 Ameren Ameren Missouri Ameren Illinois Genco 2011:

The financial statements of Ameren, Ameren Illinois and Genco are prepared on a consolidated basis. Ameren Missouri has no subsidiaries, and therefore its financial statements were not prepared on a consolidated basis. All significant intercompany transactions have been eliminated. All tabular dollar amounts are in millions, unless otherwise indicated. Our accounting policies conform to GAAP. Our financial statements reflect all adjustments (which include normal, recurring adjustments) that are necessary, in our opinion, for a fair presentation of our results. The preparation of financial stat ements in conformity with GAAP requires that Ameren management make certain estimates and assumptions. Such estimates and assumptions affect reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the dates of financial statements, and the reported amounts of revenues and expenses during the reported periods. Actual results could differ from those estimates. During the second quarter of 2011, Genco identified an error in the cash flow statement classification of a capital contribution from Ameren that affected Genco's year ended December 31, 2010. For the year ended December 31, 2010, Genco's previously reported cash flows provided by operating activities were $280 million, and cash flows used in financing activities were $251 million. As corrected herein, Genco's cash flows provided by operating activities were $304 million and cash flows used in financing activities were $275 million. This correction had no impact on Ameren's previously reported consolidated statement of cash flows.
RegulationCertain Ameren subsidiaries are regulated by the MoPSC, the ICC, and FERC. In accordance with authoritative accounting guidance regarding accounting for the effects of certain types of regulation, Ameren Missouri and Ameren Illinois defer certain costs as assets
pursuant to actions of rate regulators or based on the expectation they will be able to recover such costs in rates charged to customers. Ameren Missouri and Ameren Illinois also defer certain amounts as liabilities pursuant to actions of rate regulators or based on the expectation that such amounts will be returned to customers in future rates. Regulatory assets and liabilities are amortized consistent with the period of expected regulatory treatment. See Note 2 - Rate and Regulatory Matters for additional information on regulatory assets and liabilities. In addition, other costs that Ameren Missouri and Ameren Illinois expect to recover from customers are recorded as construction work in progress and property and plant, net. See Note 3 - Property and Plant, Net. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and temporary investments purchased with an original maturity of three months or less. Allowance for Doubtful Accounts Receivable The allowance for doubtful accounts represents our best estimate of existing accounts receivable that will ultimately be uncollectible. The allowance is calculated by applying estimated loss factors to various classes of outstanding receivables, including unbilled revenue. The loss factors used to estimate uncollectible accounts are based upon both historical collections experience and management's best estimate of future c ollections success given the existing and anticipated future collections environment. Ameren Illinois has a rate mechanism that adjusts rates for bad debt expense above or below those being collected in rates. (a)(b)(b)
Table of Contents99 Property and Plant We capitalize the cost of additions to and betterments of units of property and plant. The cost includes labor, material, applicable taxes, and overhead. An allowance for funds used during construction, as discussed specifically below, is also capitalized as a cost of our rate-regulated assets. Interest incurred during construction is capitalized as a cost of merchant generation assets. Maintenance expenditures, including nuclear refueling and maintenance outages, are expensed as incurred.
When units of depreciable property are retired, the original costs, less salvage values, are charged to accumulated depreciation. Asset removal costs incurred
by our merchant generation operations that do not constitute legal obligations are expensed as incurred. Asset removal costs accrued by our rate-regulated operations that do not constitute legal obligations are classified as a regulatory liability. See Asset Retirement Obligations below and Note 3 - Property and Plant, Net, for additional information. Depreciation Depreciation is provided over the estimated lives of the various classes of depreciable property by applying composite rates on a straight-line basis to the cost basis of such property. The provision for depreciation for the Ameren Companies in 2011, 2010 and 2009 ranged from 3% to 4% of the average depreciable cost. Allowance for Funds Used During Construction In our rate-regulated operations, we capitalize the allowance for funds used during construction, or the cost of borrowed funds and the cost of equity funds (preferred
and common stockholders' equity) applicable to rate-regulated construction expenditures, as is the utility industry accounting practice. Allowance for funds used during construction does not represent a current source of cash funds. This accounting practice offsets the effect on earnings of the cost of financing current construction, and it treats such financing costs in the same manner as construction charges for labor and materials. Under accepted ratemaking practice, cash recovery of allowance for funds used during construction and other construction costs occurs when completed projects are placed in service and reflected in customer rates. The following table presents the annual allowance for funds used during construction rates that were utilized during 2011, 2010 and 2009: Goodwill and Intangible Assets Goodwill.Goodwill represents the excess of the purchase price of an acquisition over the fair value of the 2011 2010 2009 A meren 8% - 9% 8% - 9% 6% -9%
Ameren Missouri 8 8 6 Ameren Illinois 9 9 9 net assets acquired. As of December 31, 2011, Ameren's and Ameren Illinois' goodwill related to Ameren's acquisition of IP in 2004 and Ameren's acquisition of CILCORP in 2003. We evaluate goodwill for impairment as of October 31 of each year, or more frequently if events or changes in circumstances indicate that the asset might be impaired.
During the fourth quarter of 2011, Ameren and Ameren Illinois used a qualitative evaluation to assess the likelihood of a goodwill impairment based on authoritative accounting guidance issued by the FASB in 2011. That evaluation led Ameren and Ameren Illinois to believe it was more likely than not that the fair value of each of their reporting units exceeded their carrying values, resulting in no impairment in 2011. See Note 17 - Goodwill, Impairment and Other Charges for additional information including the goodwill impairment recorded in 2010.
Intangible Assets. Ameren, Ameren Missouri and Genco classify emission allowances and renewable energy credits as intangible assets. We evaluate intangible assets for impairment if events or changes in circumstances indicate that their carrying amount might be impaired. See Note 17 - Goodwill, Impairment and
Other Charges for additional inf ormation including the intangible asset impairments recorded in 2011 and 2010. At December 31, 2011, Ameren's and Ameren Missouri's intangible assets included renewable energy credits obtained through wind and solar power purchase
agreements. The b ook value of each of Ameren's and Ameren Missouri's renewable energy credits was $7 million and less than $1 million at December 31, 2011, and 2010, respectively. In July 2011, the EPA issued the CSAPR, which created new allowances for SO and NO emissions, and restricted the use of preexisting SOand NO allowances to the acid rain program and NO budget trading program, respectively. In anticipation of the CSAPR announcement, observable market prices for existing emission allowances declined materially. Consequently, during 2011, Ameren and Genco recorded a noncash, pretax impairment charge of $2 million and $1 million, respectively, which was reflected in "Goodwill, impairment and other charges" on their statements of income. Ameren Missouri recorded a $1 million impairment of its SO emission allowances by reducing a previously established regulatory liability relating to the SOemission allowances, which had no impact to earnings. On December 30, 2011, the United States Court of Appeals for the District of Columbia issued a stay of the CSAPR.
Until that court proceeding is finalized, the EPA is expected to continue to administer the CAIR and to use CAIR's allowance program for compliance. During 2010, Ameren and Genco each recognized an impairment charge of intangible assets to reduce the carrying value of SO emission allowances. The charge was reflected in "Goodwill, impairment and other charges" in their statements of income. See Note 15 - Commitments and Contingencies for additional information on emission 2x 2 x x 2 2 2 Table of Contentsallowances and the CSAPR. The book value of each of Ameren's, Ameren Missouri's, and Genco's CAIR emission allowances was less than $1 million at December 31, 2011. The book value of Ameren's, Ameren Missouri's, and Genco's CAIR emission allowances was $7 million, $2 million, and $3 million, at December 31, 2010, respectively. Renewable energy credits and emission allowances are charged to purchased power expense and fuel expense, respectively, as they are used in operations.
The following table presents amortization expense based on usage of renewable energy credits and emission allowances, net of gains from sales, for Ameren, Ameren Missouri, Ameren Illinois, and Genco during the years ended December 31, 2011, 2010, and 2009. The table below does not include the intangible as set impairment charges referenced above.
Impairment of Long-lived Assets We evaluate long-lived assets classified as held and used for impairment whe n events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Whether impairment has occurred is determined by comparing the estimated undiscounted cash flows attributable to the assets with the carrying value of the assets. If the carrying value exceeds the undiscounted cash flows, we recognize an impairment charge equal to the carrying value of the assets in excess of estimated fair value. In the period in which we determine an asset meets the held for sale criteria, we record an impairment charge to the extent the book value exceeds its fair value less cost to sell. See Note 17 - Goodwill, Impairment and Other Charges for information about Ameren's, Ameren Missouri's and Genco's impairments. Investments Ameren and Ameren Missouri evaluate for impairment the investments held in Ameren Missouri's nuclear decommissioning trust fund. Losses on assets in
the trust fund could result in higher funding requirements for decommissioning costs, which Ameren Missouri believes would be recovered in electric rates paid by its customers. Accordingly, Ameren and Ameren Missouri recognize a regulatory asset on their balance sheets for losses on investments held in the nuclear decommissioning trust fund. See Note 9 - Nuclear Decommissioning Trust Fund Investments for additional
information. 2011 2010 2009 Ameren Missouri $(a)$6 $2 Ameren Illinois 3 7 9 Genco 2 18 24 Othe r 1 4 5 A meren $6 $35 $40 (a)Less than $1 million. (b)Includes allowances consumed that were recorded through purchase accounting. (c)Consists of renewable energy credit expense for Marketing Company and emission allowances expense for AERG. (b)(b)(c)(b)Environmental Costs Liabilities for environmental costs are recorded on an undiscounted basis when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Costs are expensed or deferred as a regulatory asset when it is expected that the costs will be recovered from customers in future rates. If environmental expenditures are related to facilities currently in use, such as pollution control equipment, the cost is capitalized and depreciated over the expected life
of the asset. Unamortized Debt Discount, Premium, and Expense Discount, premium, and expense associated with long-term debt are amortized over the lives of the related issues.Revenue Operating Revenues Ameren Missouri, Ameren Illinois and Genco record operating revenue for electric or natural gas service when it is delivered to customers. We accrue an estimate of electric and natural gas revenues for service rendered but
unbilled at the end of each accounting period. Trading Activities We present the revenues and costs associated with certain energy derivative contracts designated as trading on a net basis in "Operating Revenues - Electric" and "Operating Revenues - Other."
Nuclear Fuel Ameren Missouri's cost of nuclear fuel is capitalized and then amortized to fuel expense on a unit-of-production basis. Spent fuel disposal cost is based on net kilowatthours generated and sold, and that cost is charged to expense. Purchased Gas, Power and Fuel Rate-adjustment Mechanisms Ameren's utility subsidiaries have various rate-adjustment mechanisms in place that provide for the recovery of purchased natural gas and electric fuel and purchased power costs. See Note 2 - Rate and Regulatory Matters for the regulatory assets and liabilities recorded at December 31, 2011, and 2010, related to the rate-adjustment mechanisms discussed below.
In Ameren Missouri's and Ameren Illinois' retail natural gas utility jurisdictions, changes in natural gas costs are generally reflected in billings to their natural gas utility customers through PGA clauses. The difference between actual natural gas costs and costs billed to customers in a given period are deferred as regulatory assets or liabilities. The deferred amounts are either billed or refunded to natural gas utility customers in a subsequent period.
Table of ContentsIn Ameren Illinois' retail electric utility jurisdictions, changes in purchased power costs are generally reflected in billings to their electric utility customers through pass-through rate-adjustment clau ses. The difference between actual purchased power costs and costs billed to customers in a given period are deferred as regulatory assets or liabilities. The deferred amounts are either billed or refunded to electric utility customers in a subsequent period. Ameren Missouri has a FAC that allows an adjustment of electric rates three times per year for a pass-through to customers of 95% of changes in fuel, emission allowances and purchased power costs, net of off-system revenues, including MISO costs and revenues, greater or less than the amount set in base rates, subject to MoPSC prudency review. The differences between the cost of fuel incurred and the cost of fuel recovered from Ameren Missouri's customers are deferred as regulatory assets or liabilities. The deferred amounts are either billed or refunded to Ameren Missouri's electric utility customers in a subsequent period. Accounting for MISO Transactions MISO-related purchase and sale transactions are recorded by Ameren, Ameren Missouri and Ameren Illinois using settlement information provided by MISO. These purchase and sale transactions are accounted for on a net hourly position. We record net purchases in a single hour in "Operating Expenses - Purchased power" and net sales in a single hour in "Operating Revenues -
Electric" in our statements of income. On occasion, prior-period transactions will be resettled outside the routine settlement process because of a change in MISO's tariff or a material interpretat ion thereof. In these cases, Ameren, Ameren Missouri and Ameren Illinois recognize expenses associated with resettlements once the resettlement is probable and the resettlement amount can be estimated.
Stock-based Compensation Stock-based compensation cost is measured at the grant date based on the fair value of the award. Ameren recognizes as compensation expense the estimated fair value of stock-based compensation on a straight-line basis over the requisite service period. See Note 12 -
Stock-based Compensation for additional information. Excise Taxes Excise taxes imposed on us are reflected on Ameren Missouri customer electric bills and on Ameren Missouri and Ameren Illinois customer natural gas bills. They are recorded gross in "Operating Revenues - Electric", "Operating Revenues - Gas" and "Operating Expenses - Taxes other than income taxes" on the statement of income. Excise taxes reflected on Ameren Illinois electric customer bills are imposed on the consumer and are therefore not included in revenues and expenses. They are recorded as tax collections payable and included in "Taxes accrued" on the balance sheet. The following table presents excise taxes recorded in "Operating Revenues - Electric",
"Operating Revenues - Gas" and "Operating Expenses -
Taxes other than income taxes" for the years ended 2011, 2010 and 2009: Income Taxes Ameren uses an asset and liability approach for its financial accounting and reporting of income taxes, in accordance with authoritati ve accounting guidance. Deferred tax assets and liabilities are recognized for transactions that are treated differently for financial reporting and income tax return purposes. These deferred tax assets and liabilities are based on statutory tax rates.
We recognize that regulators will probably reduce future revenues for deferred tax liabilities that were
initially recorded at rates in excess of the current statutory rate. Therefore, reductions in the deferred tax liability, which were recorded because of decreases in the statutory rate, have been credited to a regulatory liability.
A regulatory asset has been established to recognize the probable recovery in rates of future income taxes, resulting principally from the reversal of allowance for
funds used during construction. This refers to equity and temporary differences related to property and plant acquired before 1976 that were unrecognized temporary differences prior to the adoption of the authoritative accounting guidance for income taxes. Investment tax credits used on tax returns for prior years have been deferred for book purposes; the credits are being amortized over the useful lives of the related investment. Deferred income taxes were recorded on the temporary difference represented by the deferred investment tax credits and a corresponding regulatory liability. This recognizes the expected reduction in rate revenue for future lower income taxes associated with the amortization of the investment tax credits. See Note 13 - Income Taxes. Ameren Missouri, Ameren Illinois and Genco are parties to a tax sharing agreement with Ameren that provides for the allocation of consolidated tax liabilities.
The tax sharing agreement specifies that each party be allocated an amount of tax similar to that which would be owed had the party been separately subject to tax. Any net benefit attributable to the parent is reallocated to other members. That allocation is treated as a contribution of capital to the party receiving the benefit. Noncontrolling Interests Ameren's noncontrolling interests comprised the 20% of EEI not owned by Ameren and the preferred stock not subject to mandatory redemption of Ameren's subsidiaries.

This noncontrolling interest is classified as a component of equity separate from Genco's equity in its consolidated balance sheet. Earnings per Share There were no material differences between Ameren's basic and diluted earnings per share amounts in 2011, 2010, and 2009. The number of stock options, restricted stock shares, and performance share units outstanding was immaterial. There were no assumed stock option conversions in 2009 and 2010, as the remaining stock options were not dilutive. All of Ameren's stock options expired in February 2010. Accounting Changes and Other Matters The following is a summary of recently adopted authoritative accounting guidance as well as guidance issued but not yet adopted that could impact the Ameren
Companies. Disclosures about an Employer's Participation in a Multiemployer Plan In September 2011, FASB amended its guidance to require employers to provide additional disclosures for multiemployerpension plans and multiemployer other postretirement benefit plans. This guidance was applicable to Ameren Missouri, Ameren Illinois, and Genco because they participate in their parent's (Ameren's) benefit plans.
Ameren Missouri, Ameren Illinois, and Genco adopted this guidance as of December 31, 2011. See Note 11 - Retirement Benefits for the required additional disclosures made by Ameren Missouri, Ameren Illinois and Genco, including the amount of their contributions to Ameren's benefit plans. Testing of Goodwill for Impairment In September 2011, FASB amended its guidance on testing of goodwill impairment. The amended guidance provided companies the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a two-step goodwill impairment test. As permitted, Ameren and Ameren Illinois early adopted the amended guidance for the annual goodwill impairment test performed as of October 31, 2011. See Note 17 -
Goodwill, Impairment and Other Charges for additional
information.Disclosures about Fair Value Measurements See Note 8 - Fair Value Measurements for adopted guidance on fair value measur ements issued in January 2010, which became effective in its entirety for the Ameren Companies as of January 1, 2011.
In May 2011, FASB issued additional authoritative guidance regarding fair value measurements. The guidance amends the disclosure requirements for fair value measurements in order to align the principles for fair value measurements and the related disclosure requirements under GAAP and International Financial Reporting Standards. The amendments will not affect the Ameren Companies' results of operations, financial positions, or liquidity, as this guidance only requires additional disclosures. This guidance will be effective for the Ameren Companies beginning in the first quarter of
2012 with retrospective application required. Presentation of Comprehensive Income In June 2011, FASB amended its guidance on the presentation of comprehensive income in financial statements. The amended guidance will not affect the Ameren Companies' results of operations, financial positions, or liquidity. The amended guidance changes the presentation of comprehensive income in the financial statements. It requires entities to report components of comprehensive income either in a continuous statement of comprehensive income or in two separate but consecutive statements. This guidance will be effective for the Ameren Companies beginning in the first quarter of 2012. In December 2011, the FASB amended the guidance to postpone a requirement to present reclassification adjustments by income component until further guidance is issued. Asset Retirement Obligations Authoritative accounting guidance requires us to record the estimated fair value of legal obligations
associated with the retirement of tangible long-lived assets in the period in which the liabilities are incurred and to capitalize a corresponding amount as part of the book value of the related long-lived asset. In subsequent periods, we are required to make adjustments to AROs based on changes in the estimated fair values of the obligations. Corresponding increases in asset book values are depreciated over the remaining useful life of the related asset. Uncertainties as to the probability, timing, or amount of cash flows associated with AROs affect our estimates of fair value. Ameren, Ameren Missouri and Genco have recorded AROs for retirement costs associated with Ameren Missouri's Callaway energy center decommissioning costs, asbestos removal, ash ponds, and river structures. In addition, Ameren, Ameren Missouri and Ameren Illinois have recorded AROs for the disposal of certain transformers. Asset removal costs accrued by our rate-regulated operations that do not constitute legal obligations are classified as a regulatory liability. See Note 2 - Rate and
Regulatory Matters.

(g)Balance included $5 million in "Other current liabilities" on the balance sheet as of December 31, 2011. (a)(b)(a)(d)(e)(d)(f)(g)(g)Genco Asset Sale In June 2010, Genco completed a sale of 25% of its Columbia CT energy center to the city of Columbia, Missouri. Genco received cash proceeds of $18 million and recognized a $5 million pretax gain from the sale. In June 2011, Genco completed the sale of its remaining interest in the Columbia CT energy center to the city of Columbia, Missouri. Genco received cash proceeds of $45 million and recognized an $8 million pretax gain from the sale. Effective with the sale, the power purchase agreements between Marketing Company and the city of Columbia were terminated. Also in 2011, Genco sold additional property and assets for cash proceeds of $4 million, which resulted in pretax gains of $4 million. Medina Valley Sale in 2012 In February 2012, Ameren completed the asset sale of its Medina Valley energy center's net property and plant for cash proceeds of $16 million and an additional
$1 million payment at the two-year anniversary date of the sale if there are no violations of representations and warranties contained in the sale agreement. Employee Separation and Other Charges During the fourth quarter of 2011, as part of efforts to reduce operations and maintenance expenses, Ameren Missouri and Ameren Services extended voluntary separation offers consistent with Ameren's standard management separation program to eligible management and labor union-represented employees. Approximately 340 employees of Ameren Missouri and Ameren Services accepted the offers and left their employment by December 31, 2011. Ameren and Ameren Missouri recorded a pretax charge to earnings of $28 million and
$27 million, respectively, for the severance costs related
to these offers. These charges were recorded in "Other operations and maintenance expense" in each company's statement of income for the year ended December 31, 2011. Substantially all of the severance costs will be paid in the first quarter of 2012 and were recorded in "Accounts and wages payable" on each company's balance sheet at December 31, 2011. The severance costs related to participating Ameren Services employees were allocated to affiliates consistent with the terms of its support services agreement, which is described in Note 14 - Related Party Transactions. Also during 2011, Genco ce ased operations of its Meredosia and Hutsonville energy centers. The closure of these energy centers at the end of 2011 resulted in the elimination of 90 positions. Ameren and Genco each recorded a $4 million pretax charge for related severance and relocation costs to "Goodwill, impairment and other charges" in their statements of income for the year ended December 31, 2011. The severance costs will be substantially paid during the first quarter of 2012 and were accrued in "Accounts and wages payable" on each company's balance sheet at December 31, 2011. See Note 17 - Goodwill, Impairment and Other Charges for additional information.
Table of ContentsIn 2010, Ameren's Merchant Generation segment initiated an involuntary separation program to reduce positions under the terms and benefits consistent with Ameren's standard management separation program.
Ameren and Genco recorded a pretax charge to earnings of $4 million in 2010 for the severance costs related to this program. These charges were recorded in "Other operations and maintenance expense" on Ameren's and Genco's consolidated statement of income. In 2009, Ameren initiated voluntary and involuntary separation programs under terms and benefits consistent with Ameren's standard management severance program. Ameren recorded a pretax charge to earnings of
$17 million (Ameren Missouri - $8 million, Ameren Illinois - $3 million, Genco - $5 million) for the severance costs related to both the voluntary and involuntary separation programs. These charges were recorded in "Other operations and maintenance expense" in each company's statement of income. The number of positions eliminated as a result of these separation programs was approximately 300. In its May 2010 electric rate order, the MoPSC allowed Ameren Missouri to recover the costs of this severance program from its customers. Therefore, in 2010 Ameren Missouri reclassified the 2009 "Other operations and maintenance expense" to "Regulatory assets." In addition to these programs, Genco recorded a $4 million pretax charge to 2009 earnings in conne ction with the retirement of two generating units at its Meredosia energy center and for related obsolete inventory.
NOTE 2 - RATE AND REGULATORY MATTERS Below is a summary of significant regulatory proceedings and related laws uits. We are unable to predict the ultimate outcome of these matters, the timing of the final decisions of the various agencies and courts, or the impact on our results of operations, financial position, or liquidity.
Missouri 2009 Electric Rate Order In February 2009, Noranda, Ameren Missouri's largest electric customer, and the MoOPC appealed
certain aspects of the MoPSC's 2009 electric rate order to the Circuit Court of Stoddard County, Missouri. In September 2009, the Stoddard County Circuit Court granted Noranda's request to stay the electric rate increase granted by the January 2009 MoPSC's order as it applied specifically to Noranda's electric service account until the court rendered its decision on the appeal. From the granting of the stay request until June 2010, Noranda paid into the Stoddard County Circuit Court's registry the entire amount of its monthly base rate increase and monthly FAC payments. In June 2010, when the May 2010 electric rate order became effective, Noranda ceased making base rate payments into the Stoddard County Circuit Court's registry. Noranda continued to pay into the Stod dard County Circuit Court's registry its monthly FAC payments related to electric service received during the time periods prior to the effectiveness of the May 2010 electric rate order.
In August 2010, the Stoddard County Circuit Court issued a judgment that reversed parts of the MoPSC's decision. However, upon issuance, the Stoddard County Circuit Court suspended its own judgment. Ameren Missouri filed an appeal of the Stoddard County Circuit Court's judgment with the Missouri Court of Appeals, Southern District. In November 2011, the Missouri Court of Appeals issued a ruling that upheld the MoPSC's
January 2009 electri c rate order; thereby reversing the Stoddard County Circuit Court's August 2010 decision. As
of December 31, 2011, the amount held in the Stoddard County Circuit Court's registry was $20 million. That amount was reflected in "Accounts receivable-trade" on Ameren's and Ameren Missouri's balance sheets at December 31, 2011. Ameren Missouri expects to receive all of the funds held in the Stoddard County Circuit Court's registry relating to the stay during the first quarter
of 2012. 2010 Electric Rate Order In May 2010, the MoPSC issued an order approving an increase for Ameren Missouri in annual revenues for
electric service of $230 million. The MIEC and MoOPC appealed certain aspects of the MoPSC order to the Cole County Circuit Court. In addition to the MIEC appeal, four industrial customers, who are members of MIEC, also filed a request for a stay with the Cole County Circuit Court. In December 2010, the Cole County Circuit Court granted the request of the four industrial customers to stay the MoPSC's 2010 electric rate order and required those customers to pay into the Cole County Circuit Court's registry the difference between their billings under the 2010 Missouri electric rate order and their billings under a Missouri electric rate order that became effective in June 2007, which was, at that time, the last Ameren Missouri rate order for which appeals had been exhausted. In February 2011, the four industrial customers posted the bond required by the stay. Since the bond was posted, the four industrial customers have made payments into the Cole County Circuit Court's registry equal to the difference between their base rate billings under 2010 electric rates and 2007 electric rates, as well as their FAC amounts to the extent those billings relate to service prior to the effective date of the new rates established by the 2011 electric rate order. Because of the lag between accumulations of changes in net fuel costs and the time those net fuel costs are recovered through FAC charges applied to customers' bills, the four industrial customers will continue to pay a portion of their FAC payments to the Cole County Circuit Court's registry for service prior to the effective date of the new rates by the 2011 electric rate order. It is expected that a portion of the FAC billings invoiced to these customers in September 2012 would be the last contested amount deposited into the Cole County Circuit Court's registry relating to this 2010 electric rate order appeal, pending resolution of the appeal. As of December 31, 2011, the amount held by the Cole County Table of ContentsCircuit Court, excluding the bond amount, was $15 million. This amount held in the registry was reflected in "Accounts receivable-trade" on Ameren's and Ameren Missouri's balance sheets at December 31, 2011. A Cole County Circuit Court decision is expected during the first quarter of 2012 on the MIEC's and MoOPC's appeal. We cannot predict the ultimate outcome of this proceeding, which could have a material effect on Ameren's and Ame ren Missouri's results of operations, financial position, and liquidity. If the MoPSC's 2010 electric rate order is ultimately upheld, Ameren Missouri will receive all of the funds held in the Cole County Circuit Court's registry, plus accrued interest. If Ameren Missouri were to conclude that some portion of the rate increase resulting from the 2010 electric rate order was probable of refund to Ameren Missouri's customers, a charge to earnings would be recorded for the estimated amount of refund in the period in which that determination was made. At this time, Ameren Missouri does not believe any aspect of the 2010 MoPSC's electric rate order is probable of refund to Ameren Missouri's customers. Therefore, no reserve has been established. 2011 Electric Rate Order In July 2011, the MoPSC issued an order approving an increase for Ameren Missouri in annual revenues for
electric service of $173 million, including $52 million related to an increase in normalized net fuel costs above the net fuel costs included in base rates previously authorized by the MoPSC in its 2010 electric rate order.
The revenue increase was based on a 10.2% return on equity, a capital structure composed of 52.2% common equity, and a rate base of $6.6 billion. The rate changes became effective on July 31, 2011. The MoPSC order approved the continued use of Ameren Missouri's
vegetation management and infrastructure cost tracker, its pension and postretirement benefit cost tracker, and the FAC at the current 95% sharing level. The MoPSC order shortened the FAC recovery and refund period from 12 months to eight months. The MoPSC order denied Ameren Missouri's request for the ability to recover any under-recovery of fixed costs as a result of lower sales volumes from the implementation of energy efficiency measures. Additionally, the MoPSC orde r provided for a tracking mechanism for uncertain income tax positions. The order provides that reserves for uncertain income tax positions do not reduce rate base. However, when an uncertain income tax position liability is resolved, the order requires the creation of a regulatory asset or regulatory liability to reflect the time value (using the weighted-average cost of capital in the order) of the difference between the uncertain income tax position liability that was excluded from rate base and the final tax liability. The resulting regulatory asset or liability will be amortized over three years beginning on the effective date of new rates established in the next electric rate case. The MoPSC order disallowed the recovery of all costs of enhancements, or costs that would have been incurred absent the breach, related to the rebuilding of the Taum Sauk energy center in excess of amounts recovered from property insurance. As a result of the order, Ameren and Ameren Missouri each recorded in 2011 a pretax charge to earnings of $89 million relating to the Taum Sauk disallowance. This charge was recorded in Ameren's statement of income as "Goodwill, impairment and other charges" and recorded in Ameren Missouri's statement of income as "Loss from regulatory disallowance." In July 2011, a new law that reformed the judicial appeal process for MoPSC rate orders took effect. Among other items, the new law allows appeals to bypass the circuit court and to be made directly to the appellate court.
The new law provides that rates cannot be stayed; however, the appellate court could direct the MoPSC to revise rates. Such rate revisions could be ordered to be applied retroactively. This new law applied to judicial appeals of the MoPSC's July 2011 rate order. In August 2011, Ameren Missouri appealed the disallowance of Taum Sauk enhancements to the Missouri Court of Appeals, Western District. A decision is expected by the Missouri Court of Appeals, Western District, in 2012. Ameren Missouri cannot predict the ultimate outcome of its appeal. Pending Electric Rate Case On February 3, 2012, Ameren Missouri filed a request with the MoPSC to increase its annual revenues for electric service by $376 million. Included in this requested increase is a $103 million increase in normalized net fuel costs above the net fuel co sts included in base rates previously authorized by the MoPSC in its July 2011 electric rate order. Absent initiation of this general rate proceeding, 95% of this amount would have been reflected in rate adjustments implemented under Ameren Missouri's FAC. Approximately $85 million of the request relates to investments to improve the reliability of Ameren Missouri's infrastructure and to comply with environmental and renewable energy regulations, including the requested return on such investments, and $81 million of the request relates to recovery of the costs associated with energy efficiency programs under the MEEIA, including energy efficiency investments, which is discussed below. The electric rate increase request was based on a 10.75% return on equity, a capital structure composed of 52% common equity, an aggregate electric rate base of $6.8 billion, and a test year ended September 30, 2011, with certain pro forma adjustments expected through the anticipated true-up date of July 31, 2012. As part of its filing, Ameren Missouri requested that the MoPSC approve the implementation of a storm cost tracking mechanism, as well as plant-in-service accounting treatment. The proposed storm cost tracking mechanism would allow Ameren Missouri to record a regulatory asset or liability, as applicable, reflecting the difference between a base level of major storm restoration costs used to set rates in the current rate case
and the actual storm restoration costs, and to request recovery of such regulatory asset or Table of Contentsliability in Ameren Missouri's next rate case for amortization over a three-year period. The plant-in-service accounting treatment would permit Ameren Missouri to recover a return and to defer depreciation expense on assets placed in service but not yet reflected in customer rates. Ameren Missouri requested continued use of the FAC and the regulatory tracking mechanisms for vegetation management/infrastructure inspection costs, for pension and postretirement benefits, and for uncertain income tax
positions that the MoPSC previously authorized in earlier electric rate orders. Ameren Missouri also requested recovery of the 2011 voluntary separation program
severance costs over three years. A decision by the MoPSC in this proceeding is expected in December 2012. Ameren Missouri cannot predict the level of any electric service rate change the MoPSC may approve, when any rate change may go into effect, or whether any rate increase that may eventually be approved will be sufficient for Ameren Missouri to recover its costs and earn a reasonable return on its investments when the increase goes into effect.
MEEIA Filing The MEEIA, enacted in 2009, established a regulatory framework that, among other things, allows electric utilities to recover costs related to MoPSC-approved energy efficiency programs. The law requires the MoPSC to ensure that a utility's financial incentives are aligned with helping customers use energy more efficiently, to provide timely cost recovery, and to provide earnings opportunities associated with cost-effective energy efficiency programs. Missouri does not have a law mandating energy efficiency standards. In January 2012, Ameren Missouri made its initial filing with the MoPSC under the MEEIA. This filing proposes a three-year plan that includes a portfolio of energy efficiency programs along with a cost-recovery mechanism. If the proposal is approved, beginning in January 2013, Ameren Missouri plans to invest
$145 million over three years for the proposed energy efficiency programs. A decision by the MoPSC in this proceeding is anticipated in the second quarter of 2012. The MoPSC's order in this proceeding will not affect Ameren Missouri rates until these rates are included in an electric service rate case. Ameren Missouri anticipates that the impacts of the MoPSC's decision in this MEEIA filing will be included in rates set under its pending electric service rate case that was filed on February 3, 2012, which has an anticipated true-up date of July 31, 2012. Ameren
Missouri's pending electric rate case includes an annual revenue increase of $81 million relating to its planned
portfolio of energy efficien cy programs includ ed in its MEEIA filing. FAC Prudence Review Missouri law requires the MoPSC to complete prudence reviews of Ameren Missouri's FAC at least 18 months. In April 2011, the MoPSC issued an order with respect to its review of Ameren Missouri's FAC for the period from March 1, 2009, to September 30, 2009. In this order, the MoPSC ruled that Ameren Missouri should have included in the FAC calculation all revenues and costs associated with certain long-term partial requirements sales that were made by Ameren Missouri because of the loss of Noranda's load caused by a severe ice storm in January 2009. As a result of the order, Ameren Missouri recorded a pretax charge to earnings of $18 million, including $1 million for interest, in 2011 for its obligation to refund to Ameren Missouri's electric customers the earnings associated with these sales previously recognized by Ameren Missouri during the period from March 1, 2009, to September 30, 2009. In October 2011, Ameren Missouri began refunding the $18 million to customers through the FAC. Ameren Missouri disagrees with the MoPSC order's classification of these sales and believes that the terms of its FAC tariff did not provide for the inclusion of these sales in the FAC calculation. In June 2011, Ameren Missouri filed an appeal with the Cole County Circuit Court. A decision is expected from the Cole County
Circuit Court in 2012. Separa tely, in July 2011, Ameren Missouri filed a request with the MoPSC for an accounting authority order that would allow Ameren Missouri to defer, as a regulatory asset, fixed costs totaling $36 million that were not recovered from Noranda as a result of the loss of load caused by the severe 2009 ice storm for potential recovery in a future electric rate case. We cannot predict the ultimate outcome of these regulatory or judicial
proceedings. Ameren Missouri recognized an additional $25 million of pretax earnings associated with the same long-term partial requirements sales contracts subsequent to September 30, 2009, which were not addressed by the MoPSC order issued in April 2011. The MoPSC's FAC review for the period from October 1, 2009, to May 31, 2011, was initiated in September 2011. In October 2011, the MoPSC staff filed a recommendation with the MoPSC to direct Ameren Missouri to refund to customers, prior to the completion of the staff's prudence review, the pretax earnings associated with the same long-term partial requirements sales contracts subsequent to September 30, 2009. The MoPSC staff calculated these pretax earnings to be $26 million. We cannot predict whether the MoPSC will approve this recommendation. If Ameren Missouri were to determine that these sales were probable of refund to Ameren Missouri's electric customers, a charge to earnings would be recorded for the refund in the period in which that determination was made. Because of pending co urt appeals and regulatory review, Ameren Missouri does not currently believe these amounts are probable of refund to customers.
Renewable Energy Portfolio Requirement A ballot initiative passed by Missouri voters in November 2008 created a renewable energy portfolio requirement. Beginning in 2011, Ameren Missouri and other Missouri investor-owned utilities are required to 106 every Table of Contentspurchase or generate from renewable energy sources electricity equaling at least 2% of native load sales, with that percentage increasing in subsequent years to at least 15% by 2021, subject to a 1% limit on customer rate impacts. At least 2% of each portfolio requirement must be derived from solar ene rgy. Compliance with the renewable energy portfolio requirement can be achieved through generation or the procurement of renewable energy credits. Ameren Missour i expects that any related costs or investments will ultimately be recovered in rates.
In July 2010, the Mo PSC issued final rules implementing the state's renewable energy portfolio requirement. Ameren Missouri objected to the MoPSC rules calculating the 1% limit on customer rates. In August 2010, Ameren Missouri and other groups filed an appeal with the Cole County Circuit Court of multiple aspects of the MoPSC's rules.
In December 2011, the Cole County Circuit Court issued a ruling clarifying that the 1% customer rate increase limit is an annual rest riction, not a multiyear limit.
Illinois IEIMA In October 2011, the IEI MA was enacted into law and became effective immediately. Certain amendments to the IEIMA became effective on December 30, 2011. On January 3, 2012, Ameren Illinois elected to participate in the performance-based formula ratemaking process established pursuant to the IEIMA by filing initial performance-based formula rates with the ICC. With this filing, as required by law, Ameren Illinois' previously pending electric delivery service rate case was withdrawn.
The initial filing, based on 2010 recoverable costs and expected net plant additions for 2011 and 2012, will result in new electric delivery service rates in October 2012. Pending ICC approval, the initial filing will result in a decrease of $19 million in Ameren Illinois revenues for electric delivery service, on an annualized basis. Ameren Illinois anticipates making an update filing by May 1, 2012, based on 2011 costs and expected net plant additions for 2012, that would result in new electric delivery service rates on January 1, 2013. Ameren Illinois will participate in a performance-based formula process for dete rmining rates. The formula will provide for the recovery of actual costs of electric delivery service that are prudently incurred, reflect the utility's actual regulated capital structure, and include a formula for calculating the return on equity component of the cost of capital. The return on equity component of the formula rate will be equal to the average for the applicable calendar year of the monthly average yields of 30-year United States treasury bonds plus 590 basis points for 2012 and 580 basis points thereafter. Ameren Illinois' actual return on equity relating to electric delivery service will be subject to a collar adjustment on earnings in excess of 50 basis points above or below its allowed return. Beginning in 2012, the law provides for an annual reconciliation of revenues to costs prudently and
reasonably incurred. This annual revenue reconciliation, along with the collar adjustment, if necessary, will be collected from or refunded to customers in a subsequent year. Ameren Illinois will also be subject to five performance standards. Failure to achieve the standards will result in a reduction in the company's allowed return on equity calculated under the formula. The performance standards include improvements in service reliability to reduce both the frequency and duration of outages, improvements in customer satisfaction scores, reduction in the number of estimated bills, and a reduction in uncollectible accounts expense. The IEIMA provides for return on equity penalties totaling up to 30 basis points in 2013 through 2015, 34 basis points in 2016 through 2018, and 38 basis points in 2019 through 2022 if the performance standards are not met. The formula
ratemaking process is effective until the end of 2017, but could be extended by the Illinois General Assembly for an additional five years. The formula ratemaking process would also terminate if the average residential rate increases by more than 2.5% annually from June 2011 through May 2014.
Between 2012 and 2021, Ameren Illinois will be required to invest $625 million in capital expenditures incremental to Ameren Illinois' average electric delivery
capital expenditures for c alendar years 2008 through 2010 to modernize its distribution system. Such investments are expected to encourage economic development and to create an estimated 450 additional jobs within Illinois. Ameren Illinois is subject to monetary penalties if 450 additional jobs are not created during the peak program years. Also, Ameren Illinois will be required to contribute $1 million annually for certain nonrecoverable customer assistance programs for as long as Ameren Illinois participates in the formula ratemaking process. Ameren Illinois will also be required to make a one-time $7.5 million nonrecoverable donation to the Illinois Science and Energy Innovation Trust in 2012, as well as an approximate $1 million annual donation to the same trust for as long as it participates in the formula ratemaking process. The IEIMA does not apply to natural gas utilities. 2012 Natural Gas Delivery Service Rate Order In January 2012, the ICC issued a rate order that approved an increase in annual Ameren Illinois' revenues for natural gas delivery service of $32 million. The revenue increase was based on a 9.06% return on equity, a capital structure composed of 53.3% common equity, and a rate base of $1 billion. The rate order was based on a 2012 future test year. The rate changes became effective on January 20, 2012. In February 2012, the ICC
denied rehearing requests by Ameren Illinois and an intervenor related to the granted return on equity.
Table of Contents2010 Electric and Natural Gas Delivery Service Rate Orders During 2010, the ICC issued orders that authorized an aggregate $40 million increase in Ameren Illinois' annual electric and natural gas delivery service revenues.
In December 2010, Ameren Illinois and an intervenor appealed portions of the ICC's orders to the Appellate Court of the Fourth District of Illinois. In January 2012, the Appellate Court issued a decision that upheld the ICC's 2010 electric and natural gas delivery service rate order. Federal Electric Transmission Investment FERC, in its order issued in May 2011, approved transmission rate incentives for the Illinois Rivers project and the Big Muddy project, which will be developed by ATXI or ATX. The FERC May 2011 order approved the following rate mechanisms with respect to Ameren's Illinois Rivers and Big Muddy projects: In December 2011, MISO approved the Illinois Rivers project as well as the Spoon River and Mark Twain projects. The total investment in these three MISO-approved projects is expected to be more than $1.2 billion through 2019, with potential investment of $750 million from 2012 to 2016. All four projects are in Missouri and Illinois. Construction will begin first on the Illinois Rivers project. The Big Muddy project is currently being evaluated for inclusion in MISO's 2012 expansion plan. On December 30, 2011, ATXI made a filing with FERC seeking a forward-looking rate calculation with an annual revenue reconciliation adjustment as well as requesting the implementation of the incentives FERC approved in its May 2011 order described above for the Illinois Rivers project and the Big Muddy project. FERC is expected to issue a decision on the ATXI filing during the first quarter of 2012. 2011 Wholesale Distribution Rate Case In January 2011, Ameren I llinois filed a request with FERC to increase its annual revenues for electric delivery
service for its wholesale customers by $11 million. These wholesale distribution revenues are treated as a deduction from Ameren Illinois' revenue requirement in retail rate filings with the ICC. In March 2011, FERC issued an order authorizing the proposed rates to take effect, subject to refund when the final rates are determined. Ameren Illinois reached an agreement with two of its nine wholesale customers in 2011. The impasse with the remaining seven Full recovery of financing costs, including debt and equity, associated with construction work in progress before the asset is placed in service; Recovery of costs prudently incurred in developing project facilities that might later be abandoned due to issues outside the company's control; and Use of a hypothetical capital structure during construction that reflects a capital structure of 56%
common equit y.wholesale customers has resulted in FERC litigation. An initial decision by the FERC administrative law judge is expected in 2012 and a fi nal FERC decision may be received after 2012. We cannot predict the ultimate outcome of this proceeding or its impact on Ameren's or Ameren Illinois' results of operations, financial position, or
liquidity.
Regional Transmission Organization Ameren Missouri is a transmission owning member of MISO. Ameren Missouri received authorization from the MoPSC to participate in MISO, subject to certain conditions. Ameren Missouri's continued conditional MISO participation is authorized by the MoPSC through April 30, 2012. As required by the MoPSC, Ameren Missouri filed in November 2010 and again in August 2011 updated cost benefit studies with the MoPSC that evaluated the costs and benefits of Ameren Missouri's continued participationin MISO. Ameren Missouri's updated studies continue to show substantial benefits to Ameren Missouri customers associated with its participation in MISO.
In November 2011, Ameren Missouri, together with the MoPSC staff, the MIEC, and MISO, filed a Non-Unanimous Stipulation and Agreement (Stipulation) with the MoPSC that reflected th eir agreement that continued Ameren Missouri participation in MISO through May 31, 2016, was prudent and reasonable, subject to certain conditions. The MoOPC opposes the Stipulation, in part
because of its desire that the MoPSC impose conditions relating to ATX's involvement in transmission projects located within Ameren Missouri's service territory. These
conditions, which are not included in the Stipulation are, in Ameren Missouri's view, inappropriate and unlawful.
Ameren Missouri expects an order from the MoPSC before April 30, 2012.
FERC Order - MISO Charges Ameren Missouri and Ameren Illinois, as well as other MISO participants, have filed complaints with FERC with respect to the FERC's March 2007 order involving the reallocation of certain MISO operational costs among MISO participants retroactive to 2005. Subsequently, FERC has issued a series of orders related to the applicability and the implementation of the order, which in some cases have conflicted with previous orders. In May 2009, FERC changed the effective date for refunds such that certain operational costs would be allocated among MISO market participants beginning November 2008, instead of August 2007. In June 2009, Ameren Missouri and Ameren Illinois filed a request for rehearing. The rehearing request is pending. In June 2009, FERC issued an order dismissing rehearing requests of a November 2008 order and waiving refunds of amounts billed that were included in the MISO charge, under the assumption that there was a rate mismatch for the period April 2006 through November Table of Contents109 2007. Ameren Missouri and Ameren Illinois filed a request for rehearing in July 2009.
This rehearing request is pending. Ameren Missouri and Ameren Illinois do not believe that the ultimate resolution of these proceedings will have a material effect on their results of operations, financial
position, or liquidity.
Ameren Missouri Power Purchase Agreement with Entergy Arkansas, Inc.
Beginning in 2005, FERC issued a series of orders addressing a complaint filed in 2001 by the Louisiana Public Service Commission (LPSC) against Entergy Arkansas, Inc. (Entergy) and certain of its affiliates. The complaint alleged unjust a nd unreasonable cost allocations. As a result of the FERC orders, Entergy began billing Ameren Missouri in 2007 for additional charges under a 165-megawatt power purchase agreement, and Ameren Missouri paid those charges. Additional charges continued during the remainder of the term of the power purchase agreement, which expired August 31, 2009. Although Ameren Missouri was not a party to the FERC proceedings that gave rise to these additional charges, Ameren Missouri intervened in related
FERC proceedings. Ameren Missouri also filed a complaint with FERC against Entergy and Entergy Services, Inc. in April 2008 to challenge the additional charges. In January 2010, FERC issued a ruling that Entergy may not pass the additional charges on to Ameren Missouri. In February 2010, Entergy filed a request for rehearing of the January 2010 ruling. Ameren Missouri has not recorded any prospective refund for additional charges paid to Entergy as a result of the
FERC orders. The LPSC appealed FERC's orders regarding LPSC's complaint against Entergy Services, Inc. to the United States Court of Appeals for the District of Columbia. In April 2008, that court ordered further FERC proceedings regarding LPSC's complaint. The court ordered FERC to explain its previous denial of retroactive refunds and the implementation of prospective charges.
FERC's decision on remand of the retroactive impact of these issues could have a financial impact on Ameren Missouri. Ameren Missouri is unable to predict how FERC will respond to the court's decisions. Ameren Missouri estimates that it could incur an additional expense of up to $25 million if FERC orders retroactive application for the years 2001 to 2005. Ameren Missouri believes that the likelihood of incurring any expense is not probable, and therefore no liability has been recorded as of December 31, 2011. Ameren Missouri plans to participate in any proceeding that FERC initiates to address the
court's decisions. COLA and Early Site Permit In 2008, Ameren Missouri filed an application with the NRC for a COLA for a new 1,600-megawatt nuclear unit at Ameren Missouri's existing Callaway County, Missouri, nuclear energy center site. In 2009, Ameren Missouri suspended its efforts to build a new nuclear unit at its existing Missouri nuclear energy center site, and the NRC suspended review of the COLA. Ameren Missouri is considering filing an application to obtain an early site permit from the NRC for the Callaway energy center site. An early site permit approves a specific location for a nuclear facility; however, additional licenses would be required for the specific type and design of nuclear facility to be built at that site. An early site permit does not authorize construction of a plant. An early site permit is valid for 20 years and could be renewed for up to an additional 20 years. Attempts to pass legislation to maintain an option for nuclear power in the state of Missouri by recovering the costs of the early site permit, subject to appropriate consumer protections, were not successful during 2011. However, support for nuclear power exists in the state of Missouri, which could lead to the passage of an early site permit recovery mechanism in future legislative sessions. Ameren Missouri's pursuit of an early site permit is dependent upon enactment of a legislative framework ensuring cost recovery. As of December 31, 2011, Ameren Missouri had capitalized $69 million relating to its efforts to construct a new nuclear unit. All of these incurred costs will remain capitalized while management assesses options to maximize the value of its investment in this project. If efforts are permanently abandoned or management concludes it is probable the costs incurred will be
disallowed in rates, a char ge to earnings would be recognized in the period in which that determination was made. Pumped-storage Hydroelectric Energy Center Relicensing In June 2008, Ameren Missouri filed a relicensing application with FERC to operate its Taum Sauk pumped-storage hydroelectric energy ce nter for another 40 years. The existing FERC license expired on June 30, 2010. On July 2, 2010, Ameren Missouri received a license extension that allows Taum Sauk to continue operations until FERC issues a new license. FERC is reviewing the relicensing application. A FERC order is expected in 2012 or 2013. Ameren Missouri cannot predict the ultimate outcome of the application.
Table of ContentsRegulatory Assets and Liabilities In accordance with authoritative accounting guidance regarding accounting for the effects of certain types of regulation, Ameren Missouri and Ameren Illinois defer certain costs pursuant to actions of regulators or based on the expected ability to recover such costs in rates charged to customers. Ameren Missouri and Ameren Illinois also defer certain amounts because of actions of regulators or because of the expectation that such amounts will be returned to customers in future rates.

Under current accounting standards, regulatory assets are charged to earnings when it is no longer probable that such amounts will be recoveredthrough future revenues. To the extent that payments of regulatory liabilities are no longer probable, the amounts
are credited to earnings.

Table of ContentsThe obligations of each borrower under the respective 2010 Credit Agreements to which it is a party are several and not joint, and, except under limited circumstances relating to expenses and indemnities, the obligations of Ameren Missouri, Ameren Illinois and Genco under the respective 2010 Credit Agreements are not guaranteed by Ameren or any other subsidiary of Ameren. The maximum aggregate amount available to each borrower under each facility is shown in the following table (such amount being such borrower's "Borrowing Sublimit"): 114 2010MissouriCredit A greement 2010Genco Credit A greement 2010Illinois Credit A greement A meren$ 500 $ 500 $ 300 Ameren Missouri500 (a) (a)
Ameren Illinois (a)(a)800 Genco(a) 500 (a)(a)Not applicable. Ameren has the option to seek additional commitments from existing or new lenders to increase the total facility size of the 2010 Credit Agreements to the
following maximum amounts: 2010 Missouri Credit Agreement - $1.0 billion; 2010 Genco Credit Agreement
- $625 million; and 2010 Illinois Credit Agreement - $1.0 billion. Each of the 2010 Credit Agreements will mature and expire on September 10, 2013. In February 2011, Ameren Illinois received approval from the ICC to extend the expiration of its Borrowing Sublimit under the 2010 Illinois Credit Agreement to September 10, 2013. In June 2011, Ameren Missouri received approval from the MoPSC to extend the expiration of its borrowing sublimit under the 2010 Missouri Credit Agreement to September 10, 2013. The principal amount of each revolving loan owed by a borr ower under any of the 2010 Credit Agreements to which it is a party will be due and payable no later than September 10, 2013.
The obligations of all borrowers under the 2010 Credit Agreements are unsecured. Loans are available on a revolving basis under each of the 2010 Credit Agreements and may be repaid and, subject to satisfaction of the conditions to borrowing, reborrowed from time to time. At the election of each borrower, the interest rates on such loans will be the alternate base rate (ABR) plus the margin applicable to the particular borrower and/or the eurodollar rate plus the margin applicable to the particular borrower. The applicable margins will be determined by the borrower's long-term unsecured credit ratings or, if no such ratings are then in effect, the borrower's corporate/issuer ratings then in effect. Letters of credit in an aggregate undrawn face amount not to exceed 25% of the applicable aggregate commitment under the respective 2010 Credit Agreements are also available for issuance for the account of the borrowers thereunder (but within the $2.1
billion overall combined facility borrowing limitations of the 2010 Credit Agreements). The 2010 Credit Agreements are used to borrow cash, to issue letters of credit, and to support borrowings under Ameren's $500 million commercial paper program, Ameren Missouri's $500 million commercial paper program and Ameren Illinois' $500 million commercial paper program. Any of the 2010 Credit Agreements are available to Ameren to support borrowings under Ameren's commercial paper program, subject to bo rrowing sublimit
- s. The 2010 Missouri Credit Agreement is available to support borrowings under Ameren Missouri's commercial paper program, and the 2010 Illinois Credit Agreement is available to support borrowings under Ameren Illinois' commercial paper program. At December 31, 2011, Ameren had $148 million of commercial paper outstanding and $15 million of letters of credit outstanding, and Ameren Missouri and Ameren Illinois had no commercial paper or letters of credit outstanding. Based on outstanding borrowings and letters of credit issued under the 2010 Credit Agreements as of December 31, 2011, as well as commercial paper outstanding as of such date, the aggregate amount of credit capacity available under the 2010 Credit Agreements at December 31, 2011, was $1.9 billion. $20 Million Credit Facility (Terminated) On June 2, 2010, Ameren entered into a $20 million revolving credit facility ($20 Million Facility). Borrowings under the $20 Million Facility incurred interest at a rate equal to the applicable LIBOR plus 2.25% per annum. The obligations of Ameren under the $20 Million Facility were unsecured. No subsidiary of Ameren was a party to, guarantor of, or borrower under the facility. Ameren had no outstanding borrowings under the facility as of December 31, 2011. Ameren terminated the $20 Million Facility in January 2012. During the years ended December 31, 2011 and 2010, Ameren had average daily balances outstanding of $20 million, with a weighted-average interest rate of 2.48% and 2.54%, respectively.
Commercial Paper At December 31, 2011, and 2010, Ameren had $148 million and $269 million of commercial paper outstanding, respectively. During the years ended December 31, 2011 and 2010, Ameren had average daily commercial paper balances outstanding of $311 million and $185 million with a weighted-average interest rate of 0.87% and 0.94%, respectively. The peak short-term commercial paper outstanding during the years ended December 31, 2011, and 2010 were $435 million and
$366 million, Table of Contentsrespectively. The peak interest rate for both years was 1.46%. During 2010, the commercial paper was issued only from July through December. Indebtedness Provisions and Other Covenants The information below presents a summary of the Ameren Companies' compliance with indebtedness provisions and other covenants. The 2010 Credit Agreements contain conditions about borrowings and issuances of letters of credit, including the absence of default or unmatured default, material
accuracy of representations and warranties (excluding any representation after the closing date as to the
absence of material adverse change and material litigation), and obtaining required regulatory
authorizations. In addition, solely as it relates to borrowings under the 2010 Illinois Credit Agreement, it is a condition for any such borrowing that, at the time of and after giving effect to such borrowing, the borrower not be in violation of any limitation on its ability to incur unsecured indebtedness contained in its articles of incorporation. The 2010 Cred it Agreements also contain nonfinancial covenants, including restrictions on the ability to incur liens, to transact with affiliates, to dispose of assets, to make investments in or transfer assets to its affiliates, and to merge with other entities. The 2010 Credit Agreements require each of Ameren, Ameren Missouri, Ameren Illinois and Genco to maintain consolidated indebtedness of not more than 65% of its consolidated total capitalization pursuant to a defined calculation set forth in the agreements. As of December 31, 2011, the ratios of consolidated indebtedness to total consolidated capitalization, calculated in accordance with the provisions of the 2010 Credit Agreements, were 47%, 48%, 41% and 45%, for Ameren, Ameren Missouri, Ameren Illinois and Genco, respectively. In addition, under the 2010 Genco Credit Agreement and the 2010 Illinois Credit Agreement, Ameren is required to maintain a ratio of consolidated funds from operations plus interest expense to
consolidated interest expense of 2.0 to 1.0, to be calculated quarterly, as of the end of the most recent four fiscal quarters then ending, in accordance with the 2010 Genco Credit Agreement and the 2010 Illinois Credit Agreement, as applicable. Ameren's ratio as of December 31, 2011 was 5.1 to 1.0. Failure of a borrower to satisfy a financial covenant constitutes an immediate default under the applicab le 2010 Credit Agreement.
The 2010 Credit Agreements contain default provisions. Defaults under the 2010 Credit Agreements apply separately to each borrower; except however, that a default by Ameren Missouri, Ameren Illinois or Genco under any of the 2010 Credit Agreements will also constitute a default by Ameren under such agreement.
Defaults include a cross default with respect to a borrower under the applicable 2010 Credit Agreements if that borrower defaults under any other agreement covering outstanding indebtedness of itself and certain subsidiaries (other than project finance subsidiaries and nonmaterial subsidiaries) in excess of $25 million in the aggregate. Ameren under any 2010 Credit Agreement that exists solely as a result of a default by Ameren Missouri, Ameren Illinois or Genco thereunder will not constitute a default under any other 2010 Credit Agreement while Ameren is otherwise in compliance with all of its obligations under such other 2010 Credit Agreement.
Further, a default at the Ameren level under any 2010 Credit Agreement does not trigger a default by Ameren Missouri, Ameren Illinois or Genco under such agreement. None of the Ameren Companies' credit facilities or other financing arrangements contains credit rating triggers that would cause an event of default or acceleration of repayment of outstanding balances. At December 31, 2011, management believes that the Ameren Companies were in compliance with the provisions and covenants of their credit facilities
.Money Pools Ameren has money pool agreements with and among its subsidiaries to coordinate and provide for certain short-term cash and working capital requirements. Separate money pools are maintained for utility and non-state-regulated entities. Ameren Services is responsible for the operation and administration of the money pool agreements.
UtilityAmeren Missouri, Ameren Illinois and Ameren Services may participate in the utility money pool as both lenders and borrowers. Ameren and AERG may participate in the utility money pool only as lenders.
Ameren Services administers the utility money pool and tracks internal and external funds separately. Internal funds are surplus funds contributed to the utility money pool from participants. The primary sources of external funds for the utility money pool are the 2010 Credit Agreements and the commercial paper programs. The total amount available to the pool participants from the utility money pool at any given time is reduced by the amount of borrowings by participants, but increased to the extent that the pool participants advance surplus funds to the utility money pool or remit funds from other external sources. The availability of funds is also determined by
funding requirement limits established by regulatory authorizations.The utility money pool was established to coordinate and to provide short-term cash and working capital for the participants. Participants receiving a loan under the utility money pool agreement must repay the principal amount of such loan, together with accrued interest.

All participants may borrow from or lend to the non-state-regu lated money pool, except for Ameren Services, which may participate only as a borrower. The total amount available to the pool participants at any given time is reduced by the amount of borrowings made by participants, but is increased to the
extent that the pool participants advance surplus funds to the non-state-regulated subsidiary money pool or remit funds from other external sources. The non-state-
regulated subsidiary money pool was established to coordinate and to provide short-term cash and working capital for the participants. Participants receiving a loan under the non-state-regulated subsidiary money pool agreement must repay the principal amount of such loan, together with accrued interest. The rate of interest depends on the composition of internal and external funds in the non-state-regulated subsidiary money pool. The average interest rate for borrowing under the non-state-regulated subsidiary money pool for the year ended December 31, 2011, was 0.77% (2010 - 0.77%). See Note 14 - Related Party Transactions for the amount of interest income and expense from the money pool arrangements recorded by the Ameren Companies for the years ended December 31, 2011, 2010, and 2009. Unilateral Borrowing Agreement In addition, a unilateral borrowing agreement exists among Ameren, Ameren Illinois, and Ameren Services, which enables Ameren Illinois to make short-term borrowings directly from Ameren. The aggregate amount of borrowings outstanding at any time by Ameren Illinois under the unilateral borrowing agreement and the utility money pool agreement, together with any outstanding Ameren Illinois external credit facility borrowings or commercial paper issuances, may not exceed $500 million, pursuant to authorization from the ICC. Ameren Illinois is not currently bo rrowing under the unilateral borrowing agreement. Ameren Services is responsible for operation and administration of the unilateral borrowing agreement.

IP cancelled these preferred shares. This transaction was completed in connection with the Ameren Illinois Merger.
Table of ContentsIndenture Provisions and Other Covenants Ameren Missouri's and Ameren Illinois' indentures and articles of incorporation include covenants and provisions related to issuances of first mortgage bonds and preferred stock. Ameren Missouri and Amer en Illinois are required to meet certain ratios to issue additional first mortgage bonds and preferred stock. However, a failure to achieve these ratios would not result in a default under these covenants and provisions but would restrict the companies' ability to issue bonds or preferred stock. The following table summarizes the required and actual interest coverage ratios for interest charges and dividend coverage ratios and bonds and preferred stock issuable as of December 31, 2011, at an assumed interest rate of 6% and dividend rate of 7%.

See Note 16 - Corporate Reorganization and Discontinued Operations for additional information. Genco In November 2010, Genco's $200 million 8.35% senior notes matured and were retired with available cash on hand. (a)(b)(c)(d)Ameren's indenture does not require Ameren to comply with any quantitative financial covenants. The indenture does, however, include certain cross-default provisions. Specifically, either (1) the failure by Ameren to pay when due and upon expiration of any applicable grace period any portion of any Ameren indebtedness in
excess of $25 million or (2) the acceleration upon default of the maturity of any Ame ren indebtedness in excess of $25 million under any indebtedness agreement, including the 2010 Credit Agreements, constitutes a default under the indenture, unless such past due or accelerated debt is discharged or the accelerati on is rescinded or annulled within a specified period. Ameren Missouri, Ameren Illinois, Genco and certain other nonregistrant Ameren subsidiaries are subject to Section 305(a) of the Federal Power Act, which makes it unlawful for any officer or director of a public utility, as defined in the Federal Power Act, to participate in the making or paying of any dividend from any funds "properly included in capital account." The meaning of this limitation has never been clarified under the Federal Power Act or FERC regulations. However, FERC has consistently interpreted the provision to allow dividends to be paid as long as (1) the source of the dividends is clearly disclosed, (2) the dividends are not excessive, and (3) there is no self-dealing on the part of corporate officials. At a minimum, Ameren believes that dividends can be paid by its subsidiaries that are public utilities from net income and retained earnings. In addition, under Illinois law, Ameren Illinois may not pay any dividend on their respective stock, unless, among other things, their respective earnings and earned surplus are sufficient to declare and pay a dividend after provision is made for reasona ble and proper reserves, or unless Ameren Illinois has specific authorization from the ICC. Ameren Illinois' articles of incorporation require its dividend payments on common stock to be based on ratios of common stock to total capitalization and other provisions related to certain operating expenses and accumulations of earned surplus. Ameren Illinois committed to FERC to maintain a minimum 30% ratio of common stock equity to total capitalization after the Ameren Illinois Merger and AERG distribution. As of December 31, 2011, Ameren Illinois' ratio of common stock equity to total capitalization was 58%. Genco's indenture includes provisions that require Genco to maintain certain interest coverage and debt-to-capital ratios in order for Genco to pay dividends, to make principal or interest payments on subordinated borrowings, to make loans to or investments in affiliates, or to incur additional external, third-party indebtedness.
The following table summarizes these ratios for the 12 months ended and as of December 31, 2011:

Investments in the non-state-regulated subsidiary money pool and repayments of non-state-regulated subsidiary money pool borrowings are not subject to this incurrence test. (b)A minimum interest coverage ratio of 2.50 for the most recently ended four fiscal quarters and a debt-to-capital ratio of no greater than 60% are required for Genco to incur additional indebtedness, as defined, other than permitted indebtedness, as defined, for borrowed money. The ratios must be computed on a pro forma basis considering the additional indebtedness to be incurred and the related interest expense. Non-state-regulated subsidiary money pool borrowings are defined as permitted indebtedness and are not subject to these incurrence tests. Credit facility borrowings, including borrowings under the 2010 Genco Credit Agreement, and other borrowings from third-party, external sources are included in the definition of indebtedness and are subject to these incurrence tests. Genco's debt incurrence-related ratio restrictions under its indenture may be disregarded if both Moody's and S&P reaffirm the ratings of Genco in place at the time of the debt incurrence after considering the additional indebtedness. In order for the Ameren Companies to issue securities in the future, they will have to comply with all applicable requirements in effect at the time of any such issuances. Off-Balance-Sheet Arrangements At December 31, 2011, none of the Ameren Companies had any off-balance-sheet financing arrangements, other than operating leases entered into in the ordinary course of business. None of the Ameren Companies expect to engage in any significant off-balance-sheet financing arrange ments in the near future. (a)

See Note 8 - Fair Value Measurements for discussion of our methods of assessing the fair value of derivative instruments. Many of our physical contracts, such as our coal and purchased power contracts, qualify fo r the NPNS exception to derivative accounting rules. The revenue or expense recorded in connection with NPNS contracts is recognized at the contract price upon physical delivery. If we determine that a contract meets the definition of a derivative and is not eligible for the NPNS exception, we review the contract to determine if it qualifies for hedge accounting treatment. We also consider whether gains or losses resulting from such derivatives qualify for regulatory deferral. Contracts that qualify for cash flow hedge accounting treatment are recorded at fair value with changes in fair va lue charged or credited to accumulated OCI in the period in which the change occurs, to the extent the hedge is effective. To the extent the hedge is ineffective, the related changes in fair value are charged or credited to the statement of income in the period in which the change occurs. When the contract is settled or delivered, the net gain or loss is recorded in the statement of income. Derivative contracts that qualify for regulatory deferral are recorded at fair value, with changes in fair value recorded as regulatory assets or regulatory liabilities in the period in which the change occurs. Ameren Missouri and Ameren Illinois believe derivative gains and losses deferred as regulatory assets and regulatory liabilities are probable of recovery or refund through future rates charged to customers. Regulatory assets and regulatory liabilities are amortized to operating income as related losses and gains are reflected in rates charged to customers. Therefore, gains and losses on these derivatives have no effect on operating income. Certain derivative contracts are entered into on a regular basis as part of our risk management program but do not qualify for the NPNS exception, hedge accounting, or regulatory deferral accounting. Such contracts are recorded at fair value, with changes in fair value charged or credited to the statement of income in the period in
which the change occurs. Authoritative accounting guidance permits companies to offset fair value amounts recognized for the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a liability) against fair value amounts recognized for derivative instruments that are executed with the same counterparty under the same master netting arrangement. The Ameren Companies did not elect to adopt this guidance for any eligible financial instruments or other items. (a)(c)

Table of ContentsDerivative instruments are subject to various credit-related losses in the event of nonperformance by counterparties to the transaction. Exchange-traded contracts are supported by the financial and credit quality of the clearing members of the respective exchanges and have nominal credit risk. In all other transactions, we are exposed to credit risk. Our credit risk management program involves establishing credit limits and collateral requirements for counterparties, using master trading and netting agreements, an d reporting daily exposure to senior management. We believe that entering into master trading and netting agreements mitigates the level of financial loss that could result from default by allowing net settlement of derivative assets and liabilities. We generally enter into the following master trading and netting agreements: (1) the International Swaps and Derivatives Association Agreement, a standardized financial natural gas and electric contract; (2) the Master Power Purchase and Sale Agreement, created by the Edison Electric Institute and the National Energy Marketers Association, a standardized contract for the purchase and sale of wholesale power; and (3) the North American Energy Standards Board Inc. agreement, a standardized contract for the purchase and sale of natural gas. These master trading and netting agreements allow the counterparties to net settle sale and purchase transactions. Further, collateral requirements are calculated at a master trading and netting agreement level by counterparty. Concentrations of Credit Risk In determining our concentrations of credit risk related to derivative instruments, we review our individual counterparties and categorize each counterparty into one of eight groupings according to the primary business in which each engages. The following table presents the maximum exposure, as of December 31, 2011, and 2010, if counterparty groups were to fail completely to perform on contracts by grouping. The maximum exposure is based on the gross fair value of financial instruments, including NPNS contracts, which excludes collateral held, and does not consider the legally binding right to net transactions based on master trading and netting agreements. The potential loss on counterparty exposures is reduced by the application of master trading and netting agreements and collateral held to the extent of reducing the exposure to zero. Collateral includes both cash collateral and other collater alheld. The amount of cash collateral held by Marketing Company from counterparties and based on the contractual rights under the agreements to seek collateral and the maximum exposure as calculated under the individual master trading and netting agreements was less than $1 million and $1 million from retail companies at December 31, 2011 and 2010, respectively.

Table of Contents129 Derivatives Subject to Regulatory Deferral The following table represents the net change in market value associated with derivatives that qualify for regulatory deferral for the years ended December 31, 2011 and 2010: As part of the 2007 Illinois Electric Settlement Agreement and subsequent Illinois power procurement processes, Ameren Illinois entered into financial contracts with Marketing Company. Th ese financial contracts are derivative instruments. They are accounted for as cash flow hedges by Marketing Company and as derivatives that qualify for regulatory deferral by Ameren Illinois.
Consequently, Ameren Illinois and Marketing Company record the fair value of the contracts on their respective balance sheets and the changes to the fair value in regulatory assets or liabilities by Ameren Illinois and OCI by Marketing Company. In Ameren's consolidated financial statements, all financial statement effects of the derivative instruments entered into among affiliates were eliminated.

We use various methods to determine fair value, including market, income, and cost approaches. With these approaches, we adopt certain assumptions that market participants would use in pricing the asset or liability, including assumptions about market risk or the risks inherent in the inputs to the valuation. Inputs to valuation can be readily observable, market-corroborated, or unobse rvable. We use valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Authoritative accounting guidance established a fair value hierarchy that prioritizes the inputs used to measure fair value. All financial assets and liabilities carried at fair value are classified and disclosed in one of the following three hierarchy levels: Level 1: Inputs based on quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities are primarily exchange-traded derivatives and assets, including cash and cash equivalents and listed equity securities, such as those held in Ameren Missouri's Nuclear Decommissioning Trust Fund. Level 2: Market-based inputs corroborated by third-party brokers or exchanges based on transacted market data. Level 2 assets and liabilities include certain assets held in Ameren Missouri's Nuclear Decommissioning Trust Fund, including corporate bonds and other fixed-income securities, U.S. treasury and agency securities, and certain over-the-counter derivative instruments, including natural gas swaps and financial power transactions.
Derivative instruments classified as Level 2 are valued by
corroborated observable inputs, such as pricing services or prices from similar instruments that trade in liquid markets. Our development and corroboration process entails obtaining multiple quotes or prices from outside sources. To derive our forward view to price our derivative instruments at fair value, we average the midpoints of the bid/ask spreads. To validate forward prices obtained from outside parties, we compare the pricing to recently settled market transactions. Additionally, a review of all sources is performed to identify any anomalies or potential errors. Further, we consider the volume of transactions on certain trading platforms in our reasonableness assessment of the averaged midpoint. Level 3: Unobservable inputs that are not corroborated by market data. Level 3 assets and liabilities are valued by Table of Contents130 internally developed models and assumptions or methodologies that use signif icant unobservable inputs. Level 3 assets and liabilities include derivative instruments that trade in less liquid markets, where pricing is largely unobservable, including the financial contracts entered into between Ameren Illinois and Marketing Company. We value Level 3 instruments by using pricing models with inputs that are often unobservable in the market, as well as certain internal assumptions. Our development and corroboration process entails obtaining multiple quotes or prices from outside sources. As a part of our reasonableness review, an evaluation of all sources is performed to identify any anomalies or potential errors. We perform an analysis each quarter to determine the appropriate hierarchy level of the assets and liabilities subject to fair value measurements. Financial assets and liabilities are classified in their entirety according to the lowest level of input that is significant to the fair value measurement. All assets and liabilities whose fair value measurement is based on significant unobservable inputs are classified as Level 3. In accordance with applicable authoritative accounting guidance, we consider nonperformance risk in our valuation of derivative instruments by analyzing the credit standing of our counterparties and considering any counterparty credit enhancements (e.g., collateral). The guidance also requires that the fair value measurement of liabilities reflect the nonperformance risk of the reporting entity, as applicable.
Therefore, we have factored the impact of our credit standing as well as any potential credit enhancements into the fair value measurement of both derivative assets and derivative liabilities. Included in our valuation, and based on current market conditions, is a valuation adjustment for counterparty default derived from market data such as the price of credit default swaps, bond yields, and credit ratings. Ameren recorded net losses of $2 million, net gains of less than $1 million, and net losses of less than $1 million in 2011, 2010 and 2009, respectively, related to valuation adjustments for counterparty default risk. Genco recorded net losses of less than $1 million, net gains of less than $1 million, and net gains of less than $1 million in 2011, 2010, and 2009, respectively, related to valuation adjustments for counterparty default risk. At December 31, 2011, the counterparty default risk (asset)/liability valuation adjustment related to derivative contracts totaled $1 million, less than $1 million, $19 million, and less than $(1) million for Ameren, Ameren Missouri, Ameren Illinois and Genco, respectively. At December 31, 2010, the counterparty default risk liability valuation adjustment related to derivative contracts totaled $2 million, less than
$1 million, $21 million, and less than $1 million for Ameren, Ameren Missouri, Ameren Illinois and Genco, respectively.

Table of ContentsIn January 2010, the FASB issued amended authoritative guidance regarding fair value measurements. This guidance required disclosures regarding significant transfers into and out of Level 1 and Level 2 fair value measurements. It also required information on purchases, sales, issuances, and settlements on a gross basis in the reconciliation of Level 3 fair value measurements. This guidance was effective for us as of January 1, 2010, with the exception of guidance applicable to detailed Level 3 reconciliation disclosures, which became effective for us as of January 1, 2011. The adoption of this guidance did not have a material impact on our results of operations, financial position, or liquidity because it provides enhanced disclosure requirements only.

Table of ContentsTransfers in or out of Level 3 represent either (1) existing assets and liabilities that were previously categorized as a higher level but were recategorized to Level 3 because the inputs to the model became unobservable during the period, or (2) existing assets and liabilities that were previously classified as Level 3 but were recategorized to a higher level becausethe lowest significant input became observable during the period. Transfers between Level 2 and Level 3 were primarily caused by changes in availability of financial power trades observable on electronic exchanges from the previous reporting period for the years ended December 31, 2011 and 2010. Any reclassifications are reported as transfers out of Level 3 at the fair value measurement reported at the beginning of the period in which the changes occur. For the years ended December 31, 2011 and 2010, there were no transfers between Level 1 and Level 2 related to derivative commodity contracts. The following table summarizes all transfers between fair value hierarchy levels related to derivative commodity contracts for the years ended December 31, 2011 and 2010: See Note 11 - Retirement Benefits for the fair value hierarchy tables detailing Ameren's pension and postretirement plan assets as of December 31, 2011, as well as a table summarizing the changes in Level 3 plan assets during 2011. The Ameren Companies' carrying amounts of cash and cash equivalents, accounts receivable, short-term borrowings, and accounts payable approximate fair value because of the short-term nature of these instruments. The estimated fair value of long-term debt and preferred stock is based on the quoted market prices for same or similar issues for companies with similar credit profiles or on the current rates offered to the Ameren Companies for similar financial instruments.

Table of ContentsNOTE 10 - CALLAWAY ENERGY CENTER Under the NWPA, the DOE is responsible for disposing of spent nuclear fuel from the Callaway energy center and other commercial nuclear power plants. Under the NWPA, Ameren and other utilities who own and operate those plants are responsible for paying the disposal costs. The NWPA established the fee that these
utilities pay the federal government for disposing of the spent nuclear fuel at one mill, or one-tenth of one cent, for each kilowatt hour generated by those plants and sold. The NWPA also requires the DOE to review the nuclear waste fee against the cost of the nuclear waste disposal program and to propose to the United States Congress any fee adjustment necessary to offset the costs of the program. As required by the NWPA, Ameren and other utilities have entered into standard contracts with the federal government. The government, represented by the DOE, implements these provisions of the NWPA.
Consistent with the NWPA and its contract, Ameren Missouri collects one mill from its electric customers for each kilowatt hour of electricity that it generates and sells from its Callaway energy center. Although both the NWPA and the standard contract stated that the federal government would begin to dispose of spent nuclear fuel by 1998, the federal government has acknowledged since at least 1994 that it would not meet that deadline. The federal go vernment is not currently predicting when it will begin to meet its disposal obligation. Ameren Missouri has sufficient installed capacity at its Callaway energy center to store the spent nuclear fuel generated at Callaway through 2020 and has
the capability for additional storage capacity for spent nuclear fuel generated through the end of the energy center's current licensed life. Until January 2009, the DOE program provided for spent nuclear fuel disposal to take place at a geologic repository to be constructed at Yucca Mountain, Nevada.
In January 2009, the Obama administration announced that a repository at Yucca Mountain was unworkable and took steps to terminate the Yucca Mountain program, while acknowledging the federal government's continuing obligation to dispose of utilities' spent nuclear fuel. In January 2012, an advisory commission established by the DOE issued its report of recommendations for the storage and disposal of spent nuclear fuel. The recommendations covered topics such as the approach to siting future nuclear waste management facilities, the transport and storage of spent fuel and high-level waste, options for waste disposal, institutional arrangements for managing spent nuclear fuel and high-level wastes, and changes
needed in the handling of nuclear waste fees and of the Nuclear Waste Fund. Most of these recommendations require action by the DOE and the United States Congress.In view of the federal government's efforts to terminate the Yucca Mountain program, the Nuclear Energy Institute, a number of individual utilities, and the fee. They allege that the DOE's failure to undertake an appropriate fee adequacy review reflects the current unsettled state of the nuclear waste program. That case is pending. The DOE delay in carrying out its obligation to dispose of spent nuclear fuel from the Callaway energy center is not expected to ad versely affect the continued operation of the energy center. As a result of DOE's failure to build a repository for nuclear waste or otherwise fulfill its contract obligations, Ameren Missouri and other nuclear power plant owners have also sued DOE to recover costs incurred for ongoing storage of their spent fuel. Ameren Missouri filed a breach of contract suit in 2004 to recover $13 million in costs that it incurred through 2009. This amount included the cost of reracking the Callaway energy center's spent fuel pool, as well as certain NRC fees, and Missouri ad valorem taxes that Ameren Missouri would not have incurred had DOE performed its contractual obliga tions. In June 2011, the parties reached a settlement that included a payment to Ameren Missouri of $11 million for spent fuel storage and related costs through 2010 and, thereafter, annual payment of such costs after they are incurred through 2013 or any other mutually agreed extension. As a result of this settlement agreement, Ameren Missouri recorded a pretax reduction of $2 million and $2 million to its "Operating Expenses - Depreciation and amortization" and "Operating Expenses - Other operations and maintenance" expense line items, respectively, on its statement of income for the year ended December 31, 2011. Ameren Missouri reduced its property and plant assets by $7 million. Under the settlement, Ameren Missouri's 2004 breach of contract suit was dismissed in July 2011. In December 2011, Ameren Missouri submitted a license extension application with the NRC to extend its Callaway energy center's operating license from 2024 to 2044. There is no date by which the NRC must act in this relicensing request. If the Callaway energy center's license is extended, additional spent fuel storage will be required. Ameren Missouri plans to install a dry spent fuel storage facility at its Callaway energy center and intends to begin transferring spent fuel assemblies to this facility
by 2020. Electric utility rates charged to customers provide for the recovery of the Callaway energy center's
decommissioning cost s, which include decontamination, dismantling, and site restoration costs, over an assumed 40-year life of the nuclear center, ending with the expiration of the energy center
's current operating license in 2024. It is assumed that the Callaway energy center site will be decommissioned through the immediate dismantlement method and removed from service.
Ameren and Ameren Missouri have recorded an ARO for the Callaway energy center decommissioning costs at fair value, which represents the present value of estimated future cash outflows. Decommissioning costs are included in the costs of service used to establish electric rates for 137National Association of Regulatory Utility Commissioners sued the DOE in the United States Court of Appeals for the District of Columbia Circuit seeking the suspension of the one mill nuclear waste Ameren Missouri's customers. These costs amounted to $7 million in each of the years 2011, 2010, and 2009.
Every three years, the MoPSC requires Ameren Missouri to file an Table of Contents138 updated cost study for decommissioning its Callaway energy center. Electric rates may be adjusted at such times to reflect changed estimates. This cost study was filed with the MoPSC in September 2011. After considering the results of this updated cost study and associated financial analysis, Ameren Missouri recommended to the MoPSC that the current rate of deposits to the trust fund continues to be appropriate and does not need to be changed. Amounts collected from customers are deposited in an external trust fund to provide for the Callaway energy center's decommissioning. If the assumed return on trust assets is not earned, we believe that it is probable that any such earnings deficiency will be recovered in rates. The fair value of the nuclear decommissioning trust fund for Ameren Missouri's Callaway energy center is reported as "Nuclear decommissioning trust fund" in Ameren's consolidated balance sheet and Ameren Missouri's balance sheet. This amount is legally restricted and may be used only to fund the costs of nuclear
decommissioning. Changes in the fair value of the trust fund are recorded as an increase or decrease to the nuclear decommissioning trust fund, with an offsetting adjustment to the related regulatory asset or regulatory
liability.NOTE 11 - RETIREMENT BENEFITS The primary objective of the Ameren pension plans and postretirement benefit plans is to provide eligible employees with pension and postretirement health care
and life insurance benefits.
Ameren offers defined benefit pension and postretirement benefit plans covering substantially all of its employees. Ameren uses a measurement date of December 31 for its pension and postretirement benefit plans. Ameren Missouri, Ameren
Illinois and Genco, excluding EEI, each participate in Ameren's single-employer pension and other postretirement plans. Ameren's qualified pension plan is the Ameren Retirement Plan.
Ameren also has an unfunded non-qualified pension plan, the Ameren Supplemental Retirement Plan, which is available for certain management employees and retirees to provide a supplemental benefit when their qualified pension plan benefits are reduced to comply with Internal Revenue Code limitations. Ameren's other postretirement plans are the Ameren Retiree Medical Plan and the Ameren Group Life Insurance Plan. Separately, EEI employees and retirees participate in EEI's single-employer pension and other postretirement plans. EEI's pension plan is the Revised Retirement Plan for Employees of Electric Energy, Inc. EEI's other postretirement plans are the Group Insurance Plan for Management Employees of Electric Energy, Inc. and the Group Insurance Plan for Bargaining Unit Employees of Electric Energy, Inc. Nonaffiliated Ameren companies do not participate in the Ameren Retirement Plan, the
Ameren Supplemental Retir ement Plan, the Ameren Retiree Medical Plan, and the Ameren Group Life Insurance Plan. Ameren and Genco each consolidate EEI, and therefore, EEI's plans are reflected in Ameren's and Genco's pension and postretirement balances and disclosures.The following table presents the benefit liability recorded on the balance sheets of each of the Ameren Companies as of December 31, 2011:

Table of Contents140 Ameren determines discount rate assumptions by using an interest rate yield curve pursuant to authoritative accounting guidance on the determination of discount rates used for defined benefit plan obligations. The yield curve is based on the yields of more than 500 high-quality corporate bonds with maturities between zero and 30 years. A theoretical spot-rate curve constructed from this yield curve is then used as a guide to develop a discount rate matching the plans' payout structure. Funding Pension benefits are based on the employees' years of service and compensation. Ameren's pension plan is funded in compliance with income tax regulations and federal funding or regulato ry requirements. As a result, Ameren expects to fund its pension plan at a level equal to the greater of the pension expense or the legally required minimum contribution. Considering Ameren's assumptions at December 31, 2011, its investment performance in 2011, and its pension funding policy, Ameren expects to make annual contributions of $90 million to $150 million in each of the next five years, with aggregate estimated contributions of $580 million. We expect Ameren Missouri's, Ameren Illinois' and Genco's portion of the future funding requirements to be 51%,
33%, and 12%, respectively. These amounts are estimates. The estimates may change based on actual investment performance, changes in interest rates, changes in our assumptions, any pertinent changes in government regulations, and any voluntary contributions.
Our funding policy for postretirement benefits is primarily to fund the Voluntary Employee Beneficiary Association (VEBA) trusts to match the annual postretirement
expense. The following table presents the cash contributions made to our defined benefit retirement plan and to our postretirement plans during 2011, 2010, and 2009: Pension BenefitsPostretirement Benefits201120102009201120102009 A meren$ 103 $ 81 $ 99

(a)Investment Strategy and Policies Ameren manages plan assets in accordance with the "prudent investor" guidelines contained in ERISA. The investment committee, to the extent authority is delegated to it by the finance committee of Ameren's board of directors, implements investment strategy and asset allocation guidelines for the plan assets. The investment committee includes members of senior management. The investment committee's goals are twofold: first, to ensure that sufficient funds are available to provide the benefits at the time they are payable, and second, to maximize total return on plan assets and minimize expense volatility consistent with its tolerance for risk. Ameren delegates investment management to specialists in each asset class. As appropriate, Ameren provides the investment manager with guidelines th at specify allowable and prohibited investment types. The investment committee regularly monitors manager performance and compliance with investment guidelines. The expected return on plan assets assumption is based on historical and projected rates of return for current and planned asset classes in the investment portfolio. Projected rates of return for each asset class were estimated after an analysis of historical experience, future expectations, and the volatility of the various asset classes. After considering the target asset allocation for each asset class, we adjusted the overall expected rate of return for the portfolio for historical and expected experience of active portfolio management results compared with benchmark returns and for the effect of expenses paid from plan assets. Ameren will utilize an expected return on plan assets for its pension plan assets and postretirement plan assets of 7.75% and 7.50%,
respectively, in 2012. No plan assets are expected to be returned to Ameren during 2012.
Table of ContentsAmeren's investment committee strives to assemble a portfolio of diversified assets that does not create a significant concentration of risks. The investment committee develops asset allocation guidelines between asset classes, and it creates diversification through investments in assets that differ by type (equity, debt, real estate, private equity), duration, marketcapitalization, country, style (growth or value) and industry, among other factors. The diversification of assets is displayed in the target allocation table below. The investment committee also routinely rebalances the plan assets to adhere to the diversification goals. The investment committee's strategy reduces the concentration of investment risk; however, Ameren is still subject to overall market risk. The following table presents our target allocations for 2012 and our pension and postretirement plans' asset categories as of December 31, 2011, and 2010. In general, the U.S. large capitalization equity investments are passively ma naged or indexed, wher eas the international, emerging markets, U.S. small capitalization, and U.S. mid-ca pitalization equity investments are actively managed by investment managers. Debt securities include a broad range of fixed income vehicles. Debt security investments in high-yield securities, emerging market securities, and non-U.S. dollar-denominated securities are owned by the plans, but in limited quantities to reduce risk. Most of the debt security investments are under active management by investment managers. Real estate investments include private real estate vehicles; however, Ameren does not, by policy, hold direct
investments in real estate property. Ameren's investment in private equity funds consists of 10 different limited partnerships,with invested capital ranging from $0.1 million to $7 million each, which invest primarily in a diversified number of small U.S
.-based companies. No further commitments may be made to private equity investments without approval by the finance committee of the board of directors. Additionally, Ameren's investment committee allows investment managers to use derivatives, such as index futures, exchange traded funds, foreign exchange futures, and options, in certain situations, to increase or to reduce market exposure in an efficient and timely manner. Fair Value Measurements of Plan Assets Investments in the pension and postretirement benefit plans were stated at fair value as of December 31, 2011. The fair value of an asset is the amount that would be received upon sale in an orderly transaction between market participants at the measurement date. Cash and cash equivalents have initial maturities of three months or less and are recorded at cost plus accrued interest. The carrying amounts of cash and cash equivalents approximate fair value because of the short-term nature of these instruments. Investments traded in active markets on national or international securities exchanges are valued at closing prices on the last business day on or before the measurement date. Securities traded in over-the-counter markets are valued based on quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Derivative contracts are valued at fair value, as determined by the investment managers (or independent third parties on behalf of the investment managers), who use proprietary models and take into consideration exchange quotations on underlying instruments, dealer quotations, and other market information. The fair value of real estate is based on annual appraisal reports prepared by an independ ent real estate appraiser. 141 AssetCategoryTarget Allocation 2012Percentage of Plan Assets at December 31,20112010Pension Plan: Cash and cash equivalents 0 - 5 %2% 1%Equity securities: U.S. large capitalization29 -3933 31 U.S. small and mid-capitalization 2 -12 711 International and emerging markets 9 -1911 15 Total equit y50 -6051 57 Debt securities35 -4542 37 Real estate 0 - 9 4 4Private equity 0 - 4 1 1 Total100% 100%Postretirement Plans: Cash and cash equivalents 0 -10 %4% 4%Equity securities: U.S. large capitalization33 -4338 39 U.S. small and mid-capitalization 3 -13 810 International10 -2013 14 Total equity55 -6559 63 Debt securities30 -4037 33 Total100% 100%

Table of ContentsNOTE 12 - STOCK-BASED COMPENSATION Ameren's long-term incentive plan for eligible employees, called the Long-term Incentive Plan of 1998 (1998 Plan), was replaced prospectively by the 2006 Omnibus Incentive Compensation Plan (2006 Plan) effective May 2, 2006. The 2006 Plan provides for a maximum of 4 million common shares to be available for grant to eligible employees and directors. No new awards may be granted under the 1998 Plan. Previously granted awards have vested in accordance with their original terms and conditions. The 2006 Plan awards may be stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance share units, cash-based awards, and other stock-based awards. A summary of nonvested shares at December 31, 2011, and changes during the year ended December 31, 2011, under the 1998 Plan and the 2006 Plan are presented below: 146 Performance Share Units Restricted Shares ShareUnitsWeighted-averageFair Value per Unit Shares Weighted-averageFair Value per ShareNonvested at Januar y 1, 2011 1,142,768 $ 23.96 83,154$ 49.87 Granted 731,962 31.41 - - Dividends - - 1,005 30.04 Unearned or forfeited (565,538) 16.28 (560) 50.45 Earned and vested (152,361)29.47 (83,599) 49.89 Nonvested at December 31, 2011 1,156,831 $31.70 -$- (a)Granted under the 2006 Plan.

Also includes share units that vested due to attainment of retirement eligibility by certain employees. Actual shares issued for retirement-eligible employees will vary depending on actual performance over the three-year measurement period. (a)(b)(c)(d)(e)Ameren recorded compensation expense of $14 million, $13 million, and $13 million for the years ended December 31, 2011, 2010, and 2009, respectively, and a related tax benefit of $5 million for each of the years ended December 31, 2011, 2010, and 2009, respectively. Ameren settled performance share units and restricted shares of $4 million, $2 million, and less than $1 million for the years ended December 31, 2011, 2010, and 2009. There were no significant compensation costs capitalized during the years ended December 31, 2011, 2010, and 2009. As of December 31, 2011, total compensation cost of $17 million related to nonvested awards not yet recognized is expected to be recognized
over a weighted-average period of 20 months. Performance Share Units Performance share unit awards have been granted under the 2006 Plan. A share unit vests and entitles an employee to receive shares of Ameren common stock (plus accumulated dividends) if, at the end of the three-year performance period, certain specified performance or market conditions have been met and the individual remains employed by Ameren. The exact number of
shares issued pursuant to a share unit vary from 0% to 200% of the target award, depending on actual company performance relative to the performance goals. For performance share units granted prior to 2009, vested performance shares units must be held for a two-year period before being paid to the employee in shares of Ameren common stock. During this two-year hold period, the employee is paid dividend equivalents on a current basis. The fair value of each share unit awarded in January 2011 under the 2006 Plan was determined to be $31.41. That amount was based on Ameren's closing common share price of $28.19 at December 31, 2010, and lattice simulations. Lattice simulations are used to estimate expected share payout based on Ameren's total shareholder return for a three-year performance period relative to the designated peer group beginning January 1, 2011. The simulations can produce a greater fair value for the share unit than the closing common share price because they include the weighted payout scenarios in which an increase in the share price has occurred. The significant assumptions used to calculate fair value also included a three-year risk-free rate of 1.08%, volatility of 22% to 36% for the peer group, and Ameren's attainment of three-year average earnings per share threshold during the performance period. The fair value of each share unit awarded in January 2010 under the 2006 Plan was determined to be $32.01. That amount was based on Ameren's closing common share price of $27.95 at December 31, 2009, and lattice simulations. Lattice simulations are used to estimate expected share payout based on Ameren's total stockholder return for a three-year performance period relative to the designated peer group beginning January 1, 2010.

Restricted Stock Restricted stock awards of Ameren common stock were granted under the 1998 Plan from 2001 to 2005.
Restricted shares had the potential to vest over a seven-year period from the date of grant if Ameren achieved certain performance levels. An accelerated vesting provision included in this plan reduced the ve sting period from seven years to three years if the earnings growth rate exceeded a prescribed level. (a)(b)(c)(d)
Table of ContentsThe following table presents the components of income tax expense (benefit) for the years ended December 31, 2011, 2010, and 2009: The Illinois corporate income tax rate increased from 7.3% to 9.5%, starting in January 2011. The tax rate is scheduled to decrease to 7.75% in 2015, and it is scheduled to return to 7.3% in 2025. This corporate income tax rate increase in Illinois increased current income tax expense in 2011 by $6 million, $4 million and $3 million for Ameren, Ameren Illinois and Genco, respectively. As a result of this corporate income tax rate increase, accumulated deferred tax balances were revalued, resulting in a decrease in deferred tax expense of $2 million, $3 million and $- million for Ameren, Ameren Illinois,and Genco, respectively.

Table of ContentsA reconciliation of the change in the liability for interest on unrecognized tax benefits during the years ended December 31, 2009, 2010, and 2011, is as follows: As of December 31, 2009, December 31, 2010, and December 31, 2011, the Ameren Companies have accrued no amount for penalties with respect to unrecognized tax benefits. In the second quarter of 2011, a final settlement for the years 2005 and 2006 was reached with the Internal Revenue Service. It resulted in the reduction of uncertain tax liabilities by $39 million, $17 million, $12 million, and $4 million forAmeren, Ameren Missouri, Ameren Illinois and Genco, respectively. Ameren's federal income tax returns for the years 2007 through 2009 are before the Appeals Office of the Internal Revenue Service. Ameren's federal income tax return for the year 2010 is currently under examination. State income tax returns are generally subject to examination for a period of three years after filing of the return. The state impact of any federal changes remains subject to examination by various states for a period of up to one year after
formal notification to the states. The Ameren Companies do not currently have material state income tax issues under examination, administrative appeals, or litigation. It is expected that a partial settlement will be reached with the Appeals Office of the Internal Revenue Service in the next twelve months for the years 2007 through 2009 that would result in a decrease in uncertain tax liabilities. In addition, it is reasonably possible that other events will occur during the next 12 months that would cause the total amount of unrecognized tax benefits for the Ameren Companies to increase or decrease. However, the Ameren Companies do not believe any such increases or decreases would be material to their results of operations, financial position, or liquidity. 150 Ameren AmerenMissouri AmerenIllinoisGencoLiability for interest

These transactions primarily consist of natural gas and power purchases and sales, services received or rendered, and borrowings and lendings. Transactions between affiliates are reported as intercompany transactions on their financial statements, but are eliminated in consolidation for Ameren's financial statements. Below are the material related party agreements. Electric Power Supply Agreements Genco Power Supply Agreements The following table presents the amount of physical gigawatthour sales under Genco's related party electric power supply agreements with Marketing Company, including EEI's power supply agreement with Marketing Company, for the years ended December 31, 2011, 2010, and 2009: December 31,201120102009Genco sales to Marketing Company 21,040 21,65619,598 Genco entered into a power supply agreement, as amended (PSA), with Marketing Company, whereby Genco agreed to sell and Marketing Company agreed to purchase all of the capacity and energy available from Genco's generation fleet. Marketing Company entered into a similar PSA with AERG. Under the PSAs, revenues allocated between Genco and AERG are based on reimbursable expenses and generation. Each PSA will continue through December 31, 2022, and from year to year thereafter unless either party to the respective PSA elects to terminate the PSA by providing the other party with no less than six months advance written notice. In December 2005, EEI entered into a PSA with Marketing Company, whereby EEI agreed to sell and Marketing Company agreed to purchase all of the capacity and energy available from EEI's generation fleet. The price that Marketing Company pays for capacity is set annually based upon prevailing market prices.
Marketing Company pays spot market prices for the associated energy. In addition, EEI will at times purchase energy from Marketing Company to fulfill obligations to a nonaffiliated party. This PSA will continue through May 31, 2016, unless either party elects to terminate the PSA by providing the other party with no less than four years advance written notice or five days' written notice in the event of a default, unless the default is cured within 30 business days.
Table of ContentsCapacity Supply Agreements Ameren Illinois, as an electric load-serving entity, must acquire capacity sufficient to meet its obligations to customers. Ameren Illinois used RFP processes in early 2008, pursuant to the 2007 Illinois Electric Settlement Agreement, to contract for the necessary capacity requirements for the period from June 1, 2008, through May 31, 2009. Both Marketing Company and Ameren Missouri were among the winning suppliers in the capacity RFPs. Marketing Company contracted to supply a portion of Ameren Illinois' capacity requirements for $6 million. In addition, Ameren Missouri contracted to supply a portion of the Ameren Illinois' capacity for $1 million. In 2009, Ameren Illinois used a RFP process, administered by the IPA, to contract capacity for the period from June 1, 2009, through May 31, 2012. Both Marketing Company and Ameren Missouri were among the winning suppliers in the capacity RFP process. In April 2009, Marketing Company contracted to supply a portion of Ameren Illinois' capacity requirements to Ameren Illinois for $4 million, $9 million, and $8 million for the 12 months ending May 31, 2010, 2011, and 2012, respectively. In April 2009, Ameren Missouri contracted to supply a portion of Ameren Illinois' capacity requirements to Ameren Illinois for $2 million, $2 million, and $1 million for the 12 months ending May 31, 2010, 2011, and 2012, respectively.

In April 2010, Ameren Missouri contracted to supply a portion of Ameren Illinois' capacity requirements to Ameren Illinois for less than $1 million for the period from June 1, 2010, through May 31, 2013. Energy Swaps and Energy Products Ameren Illinois, as an electric load-serving entity, must acquire energy sufficient to meet its obligations to customers. As part of the 2007 Illinois Electric Settlement Agreement, Ameren Illinois entered into financial contracts with Marketing Company (for the benefit of Genco and AERG) to lock in energy prices for 400 to 1,000 megawatts annually of its round-the-clock power requirements during the peri od June 1, 2008, to December 31, 2012, at then-relevant market prices.
These financial contracts do not include capacity, are not load-following products, and do not involve the physical delivery of energy. These financial contracts are derivative instruments. They are accounted for as cash flow hedges by Marketing Company and as derivatives subject to regulatory deferral by Ameren Illinois. Consequently, Ameren Illinois and Marketing Company record the fair value of the contracts on their respective balance sheets and the changes to the fair value in regulatory assets or liabilities for Ameren Illinois
and OCI at Marketing Company.

These agreements have no contractual expiration date, but may be terminated by either party with three years' notice. Joint Ownership Agreement ATXI and Ameren Illinois have a joint ownership agreement to construct, own, operate, and maintain certain electric transmission assets in Illinois. Under the terms of this agreement, Ameren Illinois and ATXI are responsible for their applicable share of all costs related to the construction, operation, and maintenance of electric transmission systems. Ameren is the primary beneficiary of ATXI, and therefore consolidates ATXI. Currently, there are no construction projects or joint ownership of existing assets under this agreement. In January 2011, ATXI repaid advances for the construction of transmission assets to Ameren Illinois in the amount of $52 million, including $3 million of accrued
interest.In March 2011, Ameren Illinois and ATXI signed an agreement to transfer, at cost, all of ATXI's construction work in progress assets related to the construction of a transmission line to Ameren Illinois for $20 million.

Money Pools See Note 5 - Long-term Debt and Equity Financings for discussion of affiliate borrowing arrangements. Collateral Postings Under the terms of the 2011, 2010, and 2009 Illinois power procurement agreements entered into through a RFP process administered by the IPA, suppliers must post collateral under certain market conditions to protect Ameren Illinois in the event of nonperformance. The collateral postings are unilateral, meaning that only the suppliers would be required to post collateral. Therefore, Ameren Missouri, as a winning supplier of capacity and energy products, and Marketing Company, as a winning supplier of capacity, financial energy swaps, and energy products, may be required to post collateral. As of December 31, 2011, and 2010, there were no collateral postings required of Ameren Missouri or Marketing Company related to the 2011, 2010, and 2009 Illinois power procurement agreements.

Table of ContentsThe Price-Anderson Act is a federal law that limits the liability for claims from an incident involving any licensed United States commercial nuclear power facility. The limit is based on the number of licensed reactors. The limit of liability and themaximum potential annual payments are adjusted at least every five years for inflation to reflect changes in the Consumer Price Index. The five-year inflationary adjustment as prescribed by the most recent Price-Anderson Act renewal was effective October 29, 2008. Owners of a nuclear reactor cover this exposure through a combination of private insurance and mandatory participation in a financial protection pool, as established by Price-Anderson. Losses resulting from terrorist attacks are covered under Nuclear Electric Insurance Ltd.'s policies, subject to an industrywide aggregate policy limit of $3.24 billion within a 12-month period for coverage for such terrorist acts. If losses from a nuclear incident at the Callaway energy center exceed the limits of, or are not covered by, insurance, or if coverage is unavailable, Ameren Missouri is at risk for any uninsured losses. If a serious nuclear incident were to occur, i tcould have a material adverse effect on Ameren's and Ameren Missouri's results of operations, financial position, or liquidity.Leases We lease various facilities, office equipment, plant equipment, and rail cars under operating leases. The following table presents our lease obligation s at December 31, 2011: The following table presents total rental expense, included in operating expenses, for the years ended December 31, 2011, 2010 and 2009: 155 (f)Provides the replacement power cost insurance in the event of a prolonged accidental outage at our nuclear energy center.

Ameren's and Ameren Missouri's purchased power obligations include a 102-MW power purchase agreement with a wind farm operator that expires in 2024. Ameren's and Ameren Illinois' purchased power obligations include the Ameren Illinois power purchase agreements entered into as part of the IPA-administered power procurement process.
Included in the Other column are minimum purchase commitments under contracts for equipment, design and construction, meter reading services, and an Ameren tax credit obligation at December 31, 2011. Ameren's tax credit obligation is a $17 million note payable issued for an investment in a commercial real estate development partnership to acquire tax credits. This note payable was netted against the related investment in "Other assets" on Ameren's balance sheet at December 31, 2011, as Ameren has a legally enforceable right to offset under authoritative accounting guidance. 156 Coal Natural Gas Nuclea r Fuel PurchasedPower Methane Gas Othe r Total Ameren:

These commitments are not reflected in the above table. See
Note 7 - Derivative Financial Instruments and Note 14 - Related Party Transactions for additional information. In February 2012, a rate stability procurement for energy products and re newable energy credits was administered by the IPA for the June 2013 through May 2017 period to meet certain requirements for purchased power related to the IEIMA. Ameren Illinois contracted to purchase approximately 13 million megawatthours of energy products at an average price of approximately $31 per megawatthour. Ameren Illinois is currently reviewing Table of Contents the results of the renewable energy credits procurement proceeding. Ameren Illinois has entered into an agreement to purchase approximately 15.5 billion cubic feet of synthetic natural gas annually over a 10-year period beginning in 2016 for its natural gas customers. The agreement is contingent on the count erparty reaching certain milestones during the project development and the construction of the plant that will produce the synthetic natural gas. Construction has not begun on the plant; therefore, Ameren Illinois' obligations are not yet certain at this time. The agreement was entered into pursuant to an Illinois law, which became effective August 2, 2011, and provides that all contract costs for synthetic natural gas incurred by Ameren Illinois are reasonable and prudent and recoverable through the PGA and are not subject to review or disallowance by the ICC.
Environmental Matters We are subject to various environmental laws and regulations enforced by federal, state, and local authorities. From the beginning phases of siting and development to the ongoing operation of existing or new electric generating, transmission and distribution facilities and natural gas storage, transmission and distribution facilities, our activities involve compliance with diverse environmental laws and regulations. These laws and regulations address emissions, impacts to air, land and water, noise, protected natural and cultural resources (such as wetlands, endangered species and other protected wildlife, and archeological and historical resources), and chemical and waste handling. Complex and lengthy processes are required to obtain approvals, permits, or licenses for new, existing or modified facilities.
Additionally, the use and handling of various chemicals or hazardous materials (including wastes) requires release prevention plans and emergency response procedures.
In addition to existing laws and regulations, including the Illinois MPS that applies to our energy centers in Illinois, the EPA is developing numerous new environmental regulations that will have a significant impact on the electric utility industry. These regulations could be particularly burdensome for certain companies, including Ameren, Ameren Misso uri and Genco, that operate coal-fired energy centers. Significant new rules proposed or promulgated s ince the beginning of 2010 include the regulation of greenhouse gas emissions; revised national ambient air quality standards for SO and NO emissions; the CSAPR, which requires further reductions of SO and NO emissions from power plants; a regulation governing management of CCR and coal ash impoundments; the MATS, which requires reduction of emissions of mercury, toxic metals, and acid gases from power plants; revised NSPS for particulate matter, SO, and NO emissions from new sources; and new regulations under the Clean Water Act that could require significant capital expenditures such as new water intake structures or cooling towers at our energy centers. The EPA also plans to propose an additional rule, 2 2 2x 2 xapplicable to new and existing electric generating units, governing NSPS and emission guidelines for greenhouse gas emissions. These new regulations may be litigated, so the timing of their implementation is uncertain, as evidenced by the stay of the CSAPR by the United States Court of Appeals for the District of Columbia on December 30, 2011. Although many details of these future regulations are unknown, the combined effects of the new and proposed environmental regulations may result in significant capital expenditures and/or increased operating costs over the next five to ten years for Ameren, Ameren Missouri and Genco. Act ions required to ensure that our facilities and operations are in compliance with environmental laws and regulations could be prohibitively expensive. If they are, these regulations could require us to close or to significantly alter the operation of our energy
centers, which could have an adverse effect on our results of operations, finan cial position, and liquidity, including the impairment of plant assets. Failure to comply with environmental laws and regulations might also result in the imposition of fines, penalties, and
injunctive measures. The estimates in the table below contain all of the known capital costs to comply with existing environmental regulations and our assessment of the potential impacts
of the EPA's proposed regulation for CCR, the recently finalized MATS, the stayed CSAPR as currently designed, and the revised national ambient air quality standards for SO and NO emissions as of December 31, 2011. The estimates in the table below assume that CCR will continue to be regarded as nonhazardous. The estimates in the table below do not include the impacts of new regulations proposed by the EPA under the Clean Water
Act in March 2011 regarding cooling water intake structures as our evaluation of those impacts is ongoing. The estimates shown in the table below could change significantly depending upon a variety of factors including: additional federal or state requirements; re g ulation of greenhouse gas emissions; new national ambient air quality standards or changes to existing standards for ozone, fine particulates, SO, and NOemissions; additional rules governing air pollutant transport; finalized re gulations under the Clean Water Act; CCR bein g classified as hazardous; whether the CSAPR is implemented and whether any modifications are made to its existin g requirements; new technolo gy;expected power prices; variations in costs of material or labor; and alternative compliance strategies or investment decisions. 20122013 -20162017 - 2021Total AMO$55 $325 - $400 $845 - $1,030 $1,225 - $1,485 Genco150 100 - 125 245 - 295 495 - 570 AERG520 - 25 80 - 100 105 - 130 Ameren$210 $445 -$550 $ 1,170 -$ 1,425 $1,825 - $2,185 (a)Ameren Missouri's expenditures are expected to be recoverable from ratepayers.

Table of ContentsThe decision to make pollution control equipment investments at our Merchant Generation business depends on whether the expected future market price for power reflects the increased cost for environmental compliance. In early 2012, t here has been a decline in the market price for wholesale power because of factors such as declining natural gas prices and the stay of the CSAPR. As a result of this decline in the market price for power, as well as uncertain environmental regulations, Genco is decelerating the construction of two scrubbers at of its Newton energy center. These scrubbers were originally expected to be installed in late 2013 and spring 2014. The ultimate installation of these scrubbers, now estimated to occur between 2017 and 2021 in the table above, has been postponed until such time as the incremental investment necessary for completion is justified by visible market conditions. However, Genco will continue to incur capital costs related to the construction of these scrubbers. The table above includes Genco's estimated costs of approximately $150 million in 2012 and approximately $20 million an nually, excluding capitalized interest, from 2013 through 2016 for the construction of the two scrubbers. In addition to Genco's reduction in estimated capital expenditures, AERG is deferring precipitator upgrades at its E.D. Edwards energy center beyond 2016. The following sections describe the more significant environmental rules that affect our operations. Clean Air Act Both federal and state laws require significant reductions in SOand NO emissions that result from burning fossil fuels. In March 2005, the EPA issued regulations with respect to SO and NO emissions (the CAIR). The CAIR required generating facilities in 28 states, including Missouri and Illinois, and the District of Columbia to participate in cap-and-trade programs to reduce annual SOemissions, annual NO emissions, and ozone season NO emissions.
In December 2008, the United States Court of Appeals for the District of Columbia remanded the CAIR to the EPA for further action to remedy the rule's flaws, but allowed the CAIR's cap-and-trade programs to remain effective until they are replaced by the EPA. In July 2011, the EPA issued the CSAPR as the CAIR replacement. The CSAPR was to become effective on January 1, 2012, for SO and annual NO reductions and on May 1, 2012, for ozone season NOreductions. In the CSAPR, the EPA developed federal implementation plans for each state covered by this rule; however, each impacted state can develop its own implementation rule starting as early as 2013. The CSAPR establishes emission allowance budgets for each of the states subject to the regulation, including Missouri and Illinois. With the CSAPR, the EPA
abandoned CAIR's regional approach to cutting emissions and instead set a pollution budget for each of the impacted states based on the EPA's analysis of each
upwind state's contribution to air quality in downwind states. For Missouri and Illinois, emission reductions were required in two phases beginning 2 x 2x 2 x x 2x xin 2012, with further reductions in 2014. With the CSAPR, the EPA adopted a cap-and-trade approach that allows intrastate and limited interstate trading of emission allowances with other sources within the same program, that is, in the SO program, in the annual NO, or in ozone season NOprogram. Multiple legal challenges were filed requesting to have CSAPR partially or entirely vacated and to stay the implementation of the CSAPR while the court considers the challenges. On December 30, 2011, the United States Court of Appeals for the District of Columbia issued a stay of the CSAPR. The stay does not
invalidate the rule, but only delays its implementation until a final court ruling is issued. The United States Court of Appeals for the District of Columbia has expedited its consideration of the regulation and will hear arguments on the validity of CSAPR in April 2012. The ultimate outcome of the challenges to the regulation is uncertain. The court could uphold CSAPR or remand it back to the EPA for partial or entire revision. Until the CSAPR appeal process is concluded, the EPA will continue to administer the CAIR. On December 21, 2011, the EPA issued the final MATS under the Clean Air Act, which require emission reductions for mercury and other hazardous air pollutants, such as acid gases, toxic metals, and particulate matter by setting emission limits equal to the average emissions of the best performing 12% of existing coal and oil-fired electric generating units. Also, the rule requires reductions in hydrogen chloride emissions, which were not regulated previously, and it may require continuous monitoring systems that are not currently in place. The MATS do not require a specific control technology to achieve the emission reductions. The MATS will apply to each unit at a coal-fired power plant; however, emission compliance can be averaged for the entire power plant. Compliance is required by April 2015 or, with a case-by-case extension, by April 2016.
Separately, in January and June 2010, the EPA finalized new ambient air quality standards for SO and NO. It also announced plans for further reductions in the annual national ambient air quality standards for ozone and fine particulates. The state of Illinois and the state of Missouri will be required to develop separate attainment plans to comply with the new ambient air quality standards. Ameren, Ameren Missouri and Genco continue to assess the impacts of these new standards. In September 2011, the EPA withdrew its draft annual national ambient air quality standard for ozone and announced that it was implementing the 2008 national ambient air quality standard for ozone. The EPA is required to revisit this standard again in 2013. Ameren Missouri's current environmental compliance plan for air emissions from its energy centers includes burning ultra-low-sulfur coal and installing new or optimizing existing pollution control equipment. In July 2011, Ameren Missouri contracted to procure significantly higher volumes of lower-sulfur-content coal than Ameren Missouri's energy centers have historically burned, which will allow Ameren Missouri to eliminate or postpone
capital expenditures for pollution control equipment while 2x x 2 2 158 still Table of Contentsachieving required emissions levels. In 2010, Ameren Missouri completed the installation of two scrubbers at its Sioux energy center to reduce SO emissions. Currently, Ameren Missouri's compliance plan assumes the installation of two scrubbers within its coal-fired fleet during the next 10 years and precipitator upgrades at
multiple energy centers. However, Ameren Missouri is currently evaluating its operations and options to determine how to comply with the additional emission reductions requirements in 2014 set forth in the CSAPR, if ultimately enacted, the MATS, and other recently finalized or proposed EPA regulations. Existing Illinois state regulations already required Ameren and Genco to reduce their emissions of mercury under the MPS. Ameren's and Genco's review of the MATS indicates that the scope of the federal standards is broader than the MPS, as no exemption exists for smaller coal-fired plants. Additionally, the MATS are more stringent than the MPS because compliance with the MATS is measured on a quarterly basis and, in some cases, a thirty-day rolling basis and not annually, as allowed under state requirements. At the end of 2011, Genco ceased operations of its Meredosia and Hutsonville energy centers. The closure of these energy centers was primarily due to the expected cost of complying with CSAPR and MATS. See Note 17 -
Goodwill, Impairment and Other Charges for additional information.Genco and AERG expect to install additional, or optimize existing, pollution control equipment, or modify operations to meet new and incremental emission reduction requirements under the MPS, the MATS, or the CSAPR as they become effective. Under the MPS, as amended, Illinois generators are required to reduce mercury, SO, and NO emissions by 2015. To comply with the MPS and other air emissions laws and regulations, Genco and AERG are installing equipment designed to reduce their emissions of mercury, NO, and SO. Genco and AERG have installed a total of three scrubbers at two energy centers. Two additional scrubbers are being constructed at Genco's Newton energy center. As discussed above, the timing of the installation of these scrubbers as well as precipitator upgrades at AERG's E.D. Edwards energy center have
been delayed. The closure of Genco's Meredosia and Hutsonville energy centers will allow the Merchant Generation segment additional flexibility in the methods to achieve compliance with environmental standards. Merchant Generation and Genco will continue to review and adjust their compliance plans in light of evolving outlooks for power and capacity prices, delivered fuel costs, environment standards and compliance technologies, among other factors. The completion of Ameren's, Ameren Missouri's and Genco's review of recently finalized environmental regulations and compliance measures could result in significant increases in capital expenditures and operating costs. The compliance costs could be prohibitive at some of our energy centers as the expected return from these investments, at current market prices for energy and 2 2x x 2 Emission Allowances The Clean Air Act created marketable commodities called allowances under the acid rain program, the NO budget trading program, the CAIR, and the CSAPR. With the CSAPR, the EPA adopted a cap-and-trade approach that allows intrastate and limited interstate trading of emission allowances with other sources within the same program, that is, either the SO, annual NO, or ozone season NOprograms. As noted above, on December 30, 2011, the United States Court of Appeals for the District of Columbia issued a stay of the CSAPR. Until the CSAPR appeal process is concluded, the EPA will continue to administer the CAIR including its allowance program. See Note 1 - Summary of Significant Accounting Policies for the SO and NO emission allowance book values that were classified as intangible assets as of December 31, 2011 and 2010, and Note 17 -
Goodwill, Impairment and Other Charges for information regarding the emission allowance impairments recorded during 2011 and 2010. Environmental regulations including the CAIR and the CSAPR, the timing of the installation of pollution control equipment, fuel mix, and the level of operations, will have a significant impact on the number of allowances required for ongoing operations. The CAIR uses the acid rain program's allowances for SOemissions and created annual and ozone season NO allowances. The CSAPR, however, will not rely upon the acid rain program, the NO budget trading program, or CAIR allowances for its allowance allocation program. Instead, the EPA issued a new type of emissions allowance for each program under the CSAPR. Any unused SOallowances, annual NO
allowances, and ozone season NO allowances issued under CAIR cannot be used for compliance with CSAPR.
Ameren, Ameren Missouri and Genco expect to have adequate CAIR allowances for 2012 to avoid needing to make external purchases.
Should the CSAPR become effective as issued, Ameren, Ameren Missouri and Genco are studying their compliance options to identify additional opportunities that may exist for compliance in an economical fashion.
Ameren, Ameren Missouri and Genco may be required to purchase emission allowances, if available, to install new or optimize existing pollution control equipment, to limit generation, or take other actions to achieve compliance with the CSAPR in future phase-in years.
Global Climate Change State and federal authorit ies, including the United States Congress, have considered initiatives to limit greenhouse gas emissions and to address global climate change. Potential impacts from any climate change legislation or regulation could vary, depending upon proposed CO emission limits, the timing of
implementation of those limits, the method of distributing any allowances, the degree to which offsets are allowed and available, and provisions for cost-containment measures, such as a "safety valve" provision that provides a maximum price for emission allowances. As a result of our diverse fuel portfolio, our emissions of x 2x x 2x 2 x x 2 x x 2 159capacity, might not justify the required capital expenditures or their continued operation, which could result in the impairment of long-lived assets.
greenhouse gases vary among Table of Contents our energy centers, but coal-fired power plants are significant sources of CO. The enactment of a climate change law could result in a si gnificant rise in household costs and rates for electricity could rise significantly. The burden could fall particularly hard on electricity consumers and upon the economy in the Midwest because of the region's reliance on electricity generated by coal-fired power plants. Natural gas emits about half as much CO as coal when burned to produce electricity. Therefore, climate change regulation could cause the conversion of coal-fired power plants to natural gas, or the construction of new natural gas plants to replace coal-fired power plants. As a result, economywide shifts to natural gas as a fuel source for electricity generation also could affect the cost of heating for our utility customers and many industrial processes that use natural gas. In December 2009, the EPA issued its "endangerment finding" under the Clean Air Act which stated that greenhouse gas emissions, including CO, endanger human health and welfare and that emissions of greenhouse gases from motor vehicles contribute to that endangerment. In March 2010, the EPA issued a determination that greenhouse gas emissions from stationary sources, such as power plants, would be subject to regulation under the Clean Air Act effective the
beginning of 2011. As a result of these actions, we are required to consider the em issions of greenhouse gases in any air permit application.
Recognizing the difficulties presented by regulating at once virtually all emitters of greenhouse gases, the EPA finalized in May 2010 regulations, known as the "Tailoring Rule," that established new higher thresholds for
regulating greenhouse gas em issions from stationary sources, such as power plants. The Tailoring Rule became effective in January 2011. The rule requires any source that already has an operating permit to have greenhouse-gas-specific provisions added to its permits upon renewal. Currently, all Ameren energy centers have operating permits that, when renewed, may be modified to address greenhouse gas emissions. The Tailoring Rule also provides that if projects performed at major sources result in an increase in emissions of greenhouse gases of at least 75,000 tons per year, measured in CO equivalents, such projects could trigger permitting requirements under the NSR programs and the application of best available control technology, if any, to control greenhouse gas emissions. New major sources are also required to obtain such a permit and to install the best available control technology if their greenhouse gas emissions exceed the applicable emissions threshold.
Separately, in December 2010, the EPA announced a settlement agreement under which it would propose NSPS for greenhouse gas emissions at new and existing fossil fuel-fired power plants by July 26, 2011 and issue a final standard by May 2012. The EPA has not yet proposed a rule and has not specified a new estimate of when it will issue that standard. It is uncertain whether reductions to greenhouse gas emissions would be required at Ameren's, Ameren Missouri's or Genco's energy centers as a result of any of the EPA's new and 2 2 2 2filed. Any federal climate chan ge legislation that is enacted may preempt the EPA's regulation of greenhouse gas emissions, including the Tailor ing Rule, particularly as it relates to power plant greenhouse gas emissions. The extent to which the Tailoring Rule could have a material impact on our energy centers depends upon how state agencies apply the EPA's guidelines as to what constitutes the best available control technology for greenhouse gas emissions from power plants and whether physical changes or changes in operations subject to the rule occur at our energy centers. Although the EPA has stated its intention to regulate greenhouse gas emissions from stationary sources, such as power plants, congressional action could block or delay that effort. Future federal and state legis lation or regulations that mandate limits on the emission of greenhouse gases would likely result in significant increases in capital expenditures and operating costs, which, in turn, could lead to increased liquidity needs and higher financing costs. Moreover, to the extent Ameren Missouri requests recovery of these costs through rates, its regulators might delay or deny timely recovery of these costs. Excessive costs to comply with future legislation or regulations might force Ameren, Ameren Missouri and Genco as well as other similarly situated electric power generators to close some coal-fired facilities earlier than planned, which could lead to possible impairment of assets and reduced revenues. As a result, mandatory limits could have a material adverse impact on Ameren's, Ameren Missouri's, and Genco's results of operations, financial position, and
liquidity. Recent federal court decisions have considered the application of common law causes of action, such as nuisance, to address damages resulting from global climate change. In June 2011, the United States Supreme Court in State of Connecticut v. American Electric Powerrejected state efforts to impose liability for CO and greenhouse gases emissions under federal common law. That ruling, however, did not address whether private citizens could pursue causes of action based on state common law. In June 2011, a case called Comer v.
Murphy Oil (Comer) was filed in the United States District Court for the Southern District of Mississippi. In this litigation, a Mississippi property owner sued several industrial companies, including Ameren Missouri and Genco, alleging that CO emissions created the atmospheric conditions that intensified Hurricane Katrina.
Although we are unable to predict the outcome of the Comer litigation on our results of operations, financial position, and liquidity, Ameren believes that it has meritorious defenses. Numerous procedural and substantive challenges are expected in the Comer
litigation.The impact on us of futu re initiatives related to greenhouse gas emissions and global climate change is unknown. Compliance costs could increase as future federal legislative, federal regulatory, and state-sponsored initiatives to control greenhouse gases continue to progress, making it more likely that some form 2 2 160 future rules. Legal challenges to the EPA's greenhouse gas rules have been of greenhouse gas emissions control will eventuallybe required. Since these initiatives continue to evolve, the Table of Contentsimpact on our coal-fired energy centers and our customers' costs is unknown, but any impact would probably be negative. Our costs of complying with any mandated federal or state greenhouse gas program could have a material impact on our future results of operations, financial position, and liquidity. NSR and Clean Air Litigation The EPA is engaged in an enforcement initiative to determine whether coal-fired power plants failed to comply with the requirements of the NSR and NSPS provisions under the Clean Air Act when the plants implemented modifications. The EPA's inquiries focus on whether projects performed at power plants should have triggered various permitting requirements and the installation of pollution control equipment. In April 2005, Genco received a request from the EPA for information pursuant to Section 114(a) of the Clean Air Act. The request sought detailed operating and maintenance history data with respect to Genco's Coffeen, Hutsonville, Meredosia, Newton, and Joppa energy centers and AERG's E.D. Edwards and Duck Creek energy centers. In 2006, the EPA issued a second Section 114(a) request to Genco regarding projects at the Newton energy center. All of these facilities are coal-fired energy centers. In September 2008, the EPA issued a third Section 114(a) request regarding projects at all of Ameren's coal-fired energy centers in Illinois. We completed our response to the information requests, but we are unable to predict the outcome of this matter. Following the issuance of a Notice of Violation, in January 2011, the Department of Justice on behalf of the EPA filed a complaint against Ameren Missouri in the United States District Court for the Eastern District of Missouri. The EPA's complaint alleges that in performing projects at its Rush Island coal-fired energy center, Ameren Missouri violated provisions of the Clean Air Act and Missouri law. In January 2012, the United States District Court granted, in part, Ameren Missouri's motion to dismiss various aspects of the EPA's penalty claims.
The EPA's claims for injunctive relief, including to require the installation of pollution control equipment, remain. At present, the complaint does not include Ameren Missouri's other coal-fired energy centers, but the EPA has issued Notices of Violation under its NSR enforcement initiative against the company's Labadie, Meramec, and Sioux coal-fired energy centers. Litigation of this matter could take many years to resolve. Ameren Missouri believes its defenses to the allegations described in the complaint as well as the Notices of Violation are meritorious. Ameren Missouri will defend itself vigorously. However, there can be no assurances that it will be successful in its efforts. Ultimate resolution of these matters could have a material adverse impact on the future results of operations, financial position , and liquidity of Ameren, Ameren Missouri and Genco. A resolution could result in increased capital expenditures for the installation of pollution control equipment, increased operations and maintenance expenses, and penalties. We are unable to predict the ultimate resolution of these matters or the costs that might be incurred. However, Ameren Missouri has concluded that, while a loss may be reasonably possible, the likelihood of loss is not probable. Therefore, no reserve has been established. Clean Water Act In March 2011, the EPA announced a proposed rule applicable to cooling water intake structures at existing power plants that have the ability to withdraw more than 2 million gallons of water per day from a body of water and use at least 25 percent of that water exclusively for cooling. Under the proposed rule, affected facilities would be required either to meet mortality limits for aquatic life impinged on the plant's intake screens or to reduce intake velocity to 0.5 feet per second. The proposed rule also requires plants to meet site-specific entrainment standards or to reduce the cooling water intake flow commensurate with the intake flow of a closed-cycle cooling system. The final rule is scheduled to be issued in July 2012, with compliance expected within eight years thereafter. All coal-fired, nuclear, and combined cycle energy centers at Ameren, Ameren Missouri and Genco with cooling water systems are subject to this proposed rule. The proposed rule did not mandate cooling towers at existing facilities, as other technology options potentially could meet the site-specific standards. Ameren, Ameren Missouri and Genco are current ly evaluating the proposed rule, and their assessment of the proposed rule's impacts is ongoing. Therefore, we canno t predict at this time the capital or operating costs associated with compliance.
The proposed rule could have an adverse effect on our results of operations, financial position, and liquidity if its implementation requires the installation of cooling towers at our electric generating stations.In September 2009, the EPA announced its plan to revise the effluent guidelines applicable to steam electric generating units under the Clean Water Act. Effluent guidelines are national standards for wastewater
discharges to surface water that are based on the effectiveness of available control technology. The EPA is engaged in information collection and analysis activities in support of this rulemaking. It ha s indicated that it expects to issue a proposed rule in July 2012 and to finalize the rule in 2014. We are unable at this time to predict the impact of this development.
Remediation We are involved in a number of remediation actions to clean up hazardous waste sites as required by federal and state law. Such statutes require that responsible parties fund remediation actions regardless of their degree of fault, the legality of original disposal, or the ownership of a disposal site. Ameren Missouri and Ameren Illinois have each been identified by the federal or state governments as a potentially responsible party (PRP) at several Table of Contentscontaminated sites. Several of these sites involve facilities that were transferred by our rate-regulated utility operations in Illinois to Genco in May 2000 and to AERG in October 2003. As part of each transfer, Ameren Illinois contractually agreed to indemnify Genco and AERG for remediation costs associated with preexisting environmental contamination at the transferred sites. As of December 31, 2011, Ameren and Ameren Illinois owned or were otherwise responsible for 44 former MGP sites in Illinois. These are in various stages of investigation, evaluation, and remediation. Based on current estimated plans, Ameren and Ameren Illinois could substantially conclude remediation efforts at most of these sites by 2015. The ICC permits Ameren Illinois to recover remediation and litigation costs associated with its former MGP sites from its electric and natural gas utility customers through environmental adjustment rate riders. To be recoverable, such costs must be prudently and properly incurred. Costs are subject to annual review by the ICC. As of December 31, 2011, Ameren and Ameren Missouri own or are otherwise responsible for 10 MGP sites in Missouri and one site in Iowa. Ameren Missouri does not currently have a rate rider mechanism that permits recovery of remediation costs associated with MGP sites from utility customers. Ameren Missouri does not have any retail utility operations in Iowa that would provide a source of recovery of these remediation costs. The following table presents, as of December 31, 2011, the estimated pro bable obligation to remediate these MGP sites. Ameren Illinois is responsible for the cleanup of a former coal ash landfill in Coffeen, Illinois. As of December 31, 2011, Ameren Illinois estimated that obligation at $0.5 million to $6 million. Ameren Illinois recorded a liability of $0.5 million to represent its estimated minimum obligation for this site, as no other amount within the range was a better estimate. Ameren Illinois is also responsible for the cleanup of a landfill, underground storage tanks, and a water treatment plant in Illinois. As of December 31, 2011, Ameren Illinois recorded a liability of $0.8 million to represent its best
estimate of the obligation for these sites. Ameren Missouri has responsibility for the investigation and potential cleanup of two waste sites in Missouri as a result of federal agency mandates. One of the cleanup sites is a former coal tar distillery located in St. Louis, Missouri. In 2008, the EPA issued an administrative EstimateRecordedLiabilit y Low Hi g h Ameren$ 107$ 183 $ 107 Ameren Missouri 3 4 3 Ameren Illinois 104 179 104 (a)Recorded liability represents the estimated minimum probable obligations, as no other amount within the range provided a better estimate. (a)order to Ameren Missouri pertaining to this distillery operated by Koppers Company or its predecessor and successor companies. Ameren Missouri is the current owner of the site, but Ameren Missouri did not conduct any of the manufacturing operations involving coal tar or its byproducts. Ameren Missouri, along with two other PRPs, is currently performing a site investigation. As of December 31, 2011, Ameren Missouri estimated its obligation at $2 million to $5 million. Ameren Missouri has a liability of $2 million recorded to represent its estimated minimum obligation, as no other amount within the range was a better estimate. Ameren Missouri's other active federal agency-mandated cleanup site in Missouri is a site in Cape Girardeau. Ameren Missouri was a customer of an electrical equipment repair and disposal company that previously operated a facility at this site. A trust was established in the early 1990s by several businesses and governmental agencies to fund the cleanup of this site, which was completed in 2005. Ameren Missouri anticipates this trust fund will be sufficient to complete the remaining adjacent off-site cleanup and therefore has no
recorded liability at December 31, 2011, related to this site. Ameren Missouri also has a federal agency mandate to complete a site investigation for a site in Illinois. In 2000, the EPA notified Ameren Missouri and numerous other companies, including Solutia, that former landfills and lagoons in Sauget, Illinois, may contain soil and groundwater contamination. Th ese sites are known as Sauget Area 2. From about 1926 until 1976, Ameren Missouri operated an energy center adjacent to Sauget Area 2. Ameren Missouri currently owns a parcel of property that was once used as a landfill. Under the terms of an Administrative Order on Consent, Ameren Missouri has joined with other PRPs to evaluate the extent of potential contamination with respect to Sauget Area 2. The Sauget Area 2 investigations overseen by the EPA have been completed. The results have been submitted to the EPA, and a record of decision is expected in 2012. Once the EPA has selected a remedy, if any, it would begin negotiations with various PRPs regarding implementation. Over the last several years, numerous other parties have joined the PRP group. In addition, Pharmacia Corporation and Monsanto Company have agreed to assume the liabilities related to Solutia's former chemical waste landfill in the Sauget Area 2. As of December 31, 2011, Ameren Missouri estimated its obligation at $0.3 million to $10 million. Ameren Missouri has a liability of $0.3 million recorded to represent its estimated minimum obligation, as no other amount within the range was a better estimate. In December 2004, AERG submitted a plan to the Illinois EPA to address groundwater and surface water issues associated with the recycle pond, ash ponds, and reservoir at the Duck Creek energy center. In 2010, AERG closed the recycle pond system. Remediation work on the recycle pond was completed in the first quarter of 2011, and therefore no liability exists as of December 31, 2011.
162Our operations or those of our predecessor companies involve the use of, disposal of, and in
appropriate Table of Contentscircumstances, the cleanup of substances regulated under environmental protection laws. We are unable to determine whether such practices will result in future environmental commitments or affect our results of operations, financial position, or liquidity.
A sh Management There has been activity at both state and federal levels regarding additional regulation of ash pond facilities and CCR. In May 2010, the EPA announced proposed new regulations regarding the regulatory framework for the management and disposal of CCR, which could affect future disposal and handling costs at our energy centers.
Those proposed regulations include two options for managing CCRs under either solid or hazardous waste regulations, but either alternative would allow for some continued beneficial uses, such as recycling of CCR without classifying it as waste. As part of its proposal, the EPA is considering alternative regulatory approaches that require coal-fired power plants either to close surface impoundments, such as ash ponds, or to retrofit such facilities with liners. Existing impoundments and landfills used for the disposal of CCR would be subject to groundwater monitoring requirements and requirements related to closure and pos tclosure care under the proposed regulations. Additionally, in January 2010, EPA announced its intent to develop regulations establishing financial responsibility requirements for the electric generation industry, among other industries, and it specifically discussed CCR as a reason for developing the new requirements. Ameren, Ameren Missouri and Genco are currently evaluating all of the proposed regulations to determine whether current management of CCR, including beneficial reus e, and the use of the ash ponds should be altered. Ameren, Ameren Missouri and Genco also are evaluating the potential costs associated with compliance with the proposed regulation of CCR impoundments and landfills, which could be material, if such regulations are adopted. In addition, the Illinois EPA requested that Ameren, Ameren Missouri and Genco establish groundwater monitoring plans for their ash impoundments in Illinois.
Ameren and the Illinois EPA have established a framework for closure of ash ponds in Illinois, including the ash ponds at Venice, Hutsonville, and Duck Creek, when such facilities are ultimately taken out of service. Ameren, Ameren Missouri and Genco have recorded AROs, based on current laws, for the estimated costs of the retirement of their ash ponds. Pumped-storage Hydroelectric Facility Breach In December 2005, there was a breach of the upper reservoir at Ameren Missouri's Taum Sauk pumped-storage hydroelectric energy center. This resulted in significant flooding in the local area, which damaged a state park. Ameren Missouri settled with FERC and the state of Missouri all issues associated with the December 2005 Taum Sauk incident. The rebuilt Taum Sauk energy center became fully operational in April 2010. Ameren Missouri included certain capitalized costs associated with enhancements, or costs that would have been incurred absent the breach, at the rebuilt Taum Sauk energy center not recovered from property insurers in its 2010 electric rate case filing. However, in the July 2011 rate order, the Mo PSC disallowed all of these capitalized costs associated with the rebuilding of the Taum Sauk energy center. As a result of the order, Ameren and Ameren Missouri each recorded a pretax charge to earnings in 2011 of $89 million to reflect this disallowance. See Note 2 - Rate and Regulatory Matters for additional information about the appeal of the MoPSC's July 2011 electric rate order. Ameren Missouri had property and liability insurance coverage for the Taum Sauk incident, subject to certain limits and deductibles. Insurance did not cover some lost electric margins or penalties paid to FERC. Ameren Missouri believes that the total cost for cleanup, damage and liabilities, excluding co sts to rebuild the upper reservoir, is $209 million, which is the amount Ameren Missouri had paid as of December 31, 2011. As of December 31, 2011, Ameren Missouri had recorded expenses of $37 million, primarily in prior years (2011 -
$1 million, 2010 - $1 million, 2009 - $2 million), for items not covered by insurance. Ameren Missouri recorded a
$172 million receivable for amounts recoverable from insurance companies under liability coverage. As of December 31, 2011, Ameren Missouri had received $104 million from insurance companies for liability claims, which reduced the insurance receivable balance subject to liability coverage to $68 million. In June 2010, Ameren Missouri sued an insurance company that was providing Ameren Missouri with liability coverage on the date of the Taum Sauk incident. In the litigation, filed in the United States District Court for the Eastern District of Missouri, Ameren Missouri claimed the insurance company breached its duty to indemnify Ameren Missouri for the losses experienced from the
incident. In January 2011, the court ruled that the parties must first pursue alternative dispute resolution under the terms of their coverage agreement. In February 2011, Ameren Missouri filed an appeal of the January ruling with the United States Court of Appeals for the Eighth Circuit, seeking the ability to pursue resolution of this dispute outside of a dispute resolution process under the terms of its coverage agreement. Until Ameren's remaining liability insurance claims and the related litigation are resolved, we are unable to
determine the total impact the breach could have on
Ameren's and Ameren Missouri's results of operations, financial position, and liquid ity beyond those amounts already recognized. Asbestos-related Litigation Ameren, Ameren Missouri, Ameren Illinois and EEI have been named, along with numerous other parties, in a number of lawsuits filed by plaintiffs claiming varying degrees of injury from asbestos exposure. Most have been Table of Contentsfiled in the Circuit Court of Madison County, Illinois. The total number of defendants named in each case varies, with as many as 272 part ies named in some pending cases and as few as two in others. In the cases pending as of December 31, 2011, the average number of parties was 80. The claims filed against Ameren, Ameren Missouri, Ameren Illinois and Genco allege injury from asbestos exposure during the plaintiffs' activities at our present or former electric generating plants. Former CIPS plants are now owned by Genco, and former CILCO plants are now owned by AERG. As a part of the transfer of ownership of the CIPS and CILCO generating plants, CIPS and CILCO, now Ameren Illinois, contractually agreed to indemnify Genco and AERG, for liabilities associated with asbestos-related claims arising from activities prior to the transfer. Each lawsuit seeks unspecified damages that, if awarded at trial, typically would be shared among the various defendants. The following table presents the pending asbestos-related lawsuits filed against the Ameren Companies as of December 31, 2011: At December 31, 2011, Ameren, Ameren Missouri, Ameren Illinois and Genco had liabilities of $18 million,
$6 million, $12 million, and $- million, respectively, recorded to represent their best estimate of their obligations related to asbestos claims. Ameren Illinois has a tariff rider to recover the costs of asbestos-related litigation claims, subject to the following terms: 90% of cash expenditures in excess of the amount included in base electric rates are to be recovered from a trust fund that was established when Ameren acquired IP. At December 31, 2011, the trust fund balance was $23 million, including accumulated interest. If cash expenditures are less than the amount in base rates, Ameren Illinois will contribute 90% of the difference to the fund. Once the trust fund is depleted, 90% of allowed cash expenditures in excess of base rates will be recovered through charges assessed to customers under the tariff rider. Following the Ameren Illinois Merger, this rider is applicable only for claims that occurred within IP's historical service territory. Similarly, the rider will permit recovery only from customers within IP's historical service
territory. Illinois Sales and Use Tax Exemptions and Credits InExelon Corporation v. Department of Revenue , the Illinois Supreme Court decided in 2009 that electricity is AmerenAmeren Missouri AmerenIllinoisGencoTotal45377 (b)93(a)Total does not equal the sum of the subsidiary unit lawsuits because some of the lawsuits name multiple Ameren entities as defendants.

The general liability insurance maintained by EEI provides covera ge with respect to liabilities arisin g from asbestos-related claims. (a)tangible personal property for purposes of the Illinois income tax investment credit. In March 2010, the United States Supreme Court refused to hear the case, and the decision became final. During the second quarter of 2010, Genco and AERG began claiming Illinois sales and use tax exemptions and credits for purchase transactions related to their generation operations. The basis for those claims is that the determination in the Exelon case that electricity is tangible personal property applies to sales and use tax manufacturing exemptions and credits. On
November 2, 2011, EEI received a notice of proposed tax liability, documenting the state of Illinois' position that EEI did not qualify for the manufacturing exemption it used during 2010. Genco is challenging the State of Illinois' position. In December 2011, EEI filed a request for review by the Informal Conference Board of the Illinois Department of Revenue. Ameren and Genco do not believe that it is probable that the state of Illinois will prevail and therefore have not recorded a charge to earnings for the loss contingency. From the second quarter of 2010 through December 31, 2011, Ameren and Genco claimed manufacturing exemptions and credits of $27 million and $19 million, respectively.NOTE 16 - CORPORATE REORGANIZATION AND DISCONTINUED OPERATIONS On October 1, 2010, after receiving all necessary approvals, Ameren, CIPS, CILCO, IP, AERG and AER completed a two-step corporate internal reorganization.
The first step of the reorganization was the Ameren Illinois Merger. The second step of the reorganization involved the distribution of AERG stock from Ameren Illinois to Ameren (the AERG distribution) and the subsequent contribution by Ameren of the AERG stock to
AER.Upon the Ameren Illinois Merger, the debt and other obligations of CILCO and IP under their mortgage indentures, senior note indentures, and pollution control bond agreements become debt and obligations of Ameren Illinois. The property owned by CILCO and IP immediately before the Ameren Illinois Merger that was subject to the lien of their respective mortgage indentures remained subject to such lien, which continued to secure the bonds outstanding under such mortgage indenture
subject to the release and other provisions of such mortgage indenture. The senior secured notes of IP and CILCO remained secured by the mortgage bonds held by their respective senior note trustee, subject to the release and other provisions of the respective senior note indenture. The debt and other obligations of CIPS remained debt and obligations of Ameren Illinois. Ameren
Illinois secured the senior notes issued by CIPS with the benefit of a lien under the IP mortgage indenture. Ameren Illinois has also encumbered substantially all of the real estate, fixtures and equipment owned by CIPS immediately before the Ameren Illinois Merger with the lien of the IP mortgage indenture. At the time of the Ameren Illinois Merger, the common stock of CILCO and IP, all wholly owned by Ameren, was canceled without consideration. Then, pursuant to the Table of ContentsNOTE 17 - GOODWILL, IMPAIRMENT AND OTHER CHARGES The following table summarizes the pretax charges recognized for the years ended December 31, 2011, 2010, and 2009: 165 Goodwill Long-LivedAssets and Related Char ges Emission Allowances Total 2011: A meren$-$123$2$125 Ameren Missouri-89-89 Genco-34135 2010: Ameren 420 101 68 589 Genco 65 64 41 170 2009: Ameren 7Genco 6(a)Includes amounts for registrant and nonregistrant subsidiaries. merger agreement: (i) every two shares of each series of IP preferred stock outstanding immediately prior to the Ameren Illinois Merger were automatically converted into one share of a newly created series of Ameren Illinois preferred stock having the same payment and redemption terms as the existing series of IP preferred stock, except to the extent that IP preferred stockholders exercised their dissenters' rights in accordance with Illinois law; and (ii) each outstanding share of CIPS common and preferred stock remained outstanding, except to the extent that CIPS preferred stockholders exercised their dissenters' rights in accordance with Illinois law.
Stockholders holding approximately 8,337 shares and 423 shares of CIPS and IP preferred stock, respectively, exercised their dissenters' rights. In its application for the FERC orders approving the Ameren Illinois Merger and the AERG distribution, Ameren committed to maintain a minimum 30% equity capital structure at Ameren Illinois after the Ameren Illinois Merger and the AERG distribution. Ameren Illinois determined that the operating results of AERG qualified for discontinued operations presentation; therefore, Ameren Illinois segregated AERG's operating results and presented them separately as discontinued operations for all periods presented prior to October 1, 2010, in this report. For Ameren's financial statements, AERG's results of operation remain classified as continuing operations. The following table summarizes the operating results of Ameren Illinois' former merchant generation subsidiary, AERG, classified as discontinued operations in Ameren Illinois' statements of income for the years ended December 31, 2010, and 2009:

regulatory disallowance." Ea ch of the charges is discussed below. The goodwill and other asset impairment charges did not result in a violation of any Ameren or Ameren subsidiary debt covenants or counterparty agreements.
The charges are not expected to have a material impact on future operations. Goodwill Ameren has three reporting units, which also represent Ameren's reportable segments. The Ameren reporting units are Ameren Missouri, Ameren Illinois, and Merchant Generation. Genco has one reporting unit, Merchant Generation. Ameren Illinois has one reporting unit, Ameren Illinois. Ameren's reporting units have been defined and goodwill has been evaluated at the operating segment level in accordance with authoritative accounting guidance. Our reporting units represent businesses for which discrete financial information is available and reviewed regularly by management. We evaluate goodwill for impairment as of October 31 of each year, or more frequently if events and circumstances indicate that the asset might be impaired.
In 2011, FASB amended its guidance to simplify the testing of goodwill for impairment. The amended guidance provides an option to perform a qualitative assessment to determine whether further impairment testing is
necessary. If the qualitative ev aluation yields support that it is more likely than not that the fair value of a reporting unit exceeds its Table of ContentsThe following tables provide a reconciliation of the beginning and ending carrying amounts of goodwill by reporting unit, for Ameren, Ameren Illinois and Genco for the years ended December 31, 2011 and 2010: Ameren Ameren Illinois Genco 166 20112010 AmerenIllinois AmerenIllinois MerchantGenerationTotalGross goodwill at January 1 $ 411 $ 411 $ 420 $ 831 Accumulated impairment losses - - --Goodwill, net of accumulated impairment losses $411 $411 $420 $831 Impairment losses durin gy ea r - - 420 420 Goodwill, net of impairment losses at December 31 $411 $411 $- $411 (a)Includes amounts for Ameren registrants and nonregistrant subsidiaries. 20112010 AmerenIllinois AmerenIllinoisGross goodwill at January 1$ 411 $ 411 Accumulated impairment losses - -Goodwill, net of accumulated impairment losses$411 $411 Impairment losses during the yea r - -Goodwill, net of impairment losses at December 31$411 $411 2010Merchant Generation Gross g oodwill at Januar y 1$ 65 Accumulated impairment losses

Ameren and Ameren Illinois adopted the qualitative goodwill evaluation model for its annual goodwill impairment test conducted as of October 31, 2011. Based on the results of Ameren's and Ameren Illinois' qualitative assessment, Ameren and Ameren Illinois believe it was more likely than not that the fair value of each of their re porting units exceeded their carrying values as of October 31, 2011, indicating no impairment of Ameren's and Ameren Illinois' goodwill.
The following factors, not meant to be all-inclusive, were considered by Ameren and Ameren Illinois when assessing whether it was more likely than not that the fair value of the Ameren Illinois reporting unit exceeded its carrying value for the Oc tober 31, 2011 test: Macroeconomic conditions, including those conditions within Ameren Illinois' service territor y;Pending rate case outcomes and future rate case outcomes; Changes in laws and potent ial law changes, such as the IEIMA; During 2010, Ameren recorded a noncash impairment charge of $420 million, which represented all of the goodwill assigned to Ameren's Merchant Generation reporting unit. Genco recorded a noncash impairment charge of $65 million, which represented all the goodwill assigned to Genco's Merchant Generation reporting unit. The impairments recorded in 2010 in the Merchant Generation segment were caused by a sustained decline in market prices for electricity, industry market multiples becoming observable at lower levels than previously estimated, and potentially more stringent environmental regulations being enacted. Ameren and Ameren Illinois will continue to monitor the actual and forecasted operating results, cash flows, market capitalization, and observable industry market multiples of their reporting units for signs of possible declines in estimated fair value and potential goodwill impairment.Observable industr y market multiples; and Actual and forecasted financial performance.

Table of ContentsLong-lived Assets We evaluate long-lived assets classified as held and used for impairment whe n events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Whether impairment has occurred is determined by comparing the estimated undiscounted cash flows attributable to the assets with the carrying value of the assets. If the carrying value exceeds the undiscounted cash flows, we recognize an impairment charge equal to the carrying value of the assets in excess of estimated fair value. During 2011, the MoPSC issued an electric rate order that disallowed the recovery of all costs of enhancements, or costs that would have been incurred absent the breach, related to the rebuilding of the Taum Sauk energy center in excess of the amount recovered from property insurance. Consequently, Ameren and Ameren Missouri each reported a pretax charge to earnings of $89 million. See Note 2 - Rate and Regulatory Matters for additional information.At the end of 2011, Genco ceased operations of its Meredosia and Hutsonville energy centers. The closure of these energy centers resulted in the elimination of 90 positions. Ameren and Genco each recorded the following pretax charges to earnings during 2011 related to the closure of these energy centers: The closure of these energy centers is primarily the result of the expected cost of complying with the CSAPR and the MATS. Genco determined that environmental compliance options for these four units were uneconomical. Another factor driving the closure of these energy centers was a lack of a multiyear capacity market managed by MISO, without which Genco was not positioned to make the substantial investment for environmental controls that would be required to keep these units in service. Ameren and Genco expect to receive cash tax benefits of $22 million and $33 million, respectively, as a result of the closure of these energy centers. Previously recorded AROs for ash pond closures, river structure, and asbestos removals at these energy centers were $38 million. Ameren and Genco expect cash expenditures over the next 10 years along with associated cash tax benefits of $16 million. During 2010, Ameren and Genco evaluated their long-lived assets and recorded noncash pretax asset impairment charges of $101 million and $64 million, respectively, to reduce the carrying value of the Meredosia and Medina Valley energy centers to their estimated fair value during 2010. In 2009, Genco recorded asset impairment charges of $6 million as a result of the termination of a rail line a $26 million noncash impairment, representing the remainin g net investment in both ener gy centers; a $4 million noncash impairment of materials and supplies; and a $4 million estimate for future cash severance costs, which will be substantially paid during the first quarter
of 2012. extension project at a Genco subsidiary and an adjustment of the carrying value of an office building owned by Genco to its estimated fair value as of December 31, 2009.
The charge related to the office building was based on the net proceeds from its sale in 2010. In addition, AERG recorded an asset impairment charge of $1 million to adjust the carrying value of its Indian Trails generation facility's estimated fair value as of December 31, 2009. This charge was based on the net proceeds from the sale of the facility in January 2010. Intangible Assets We evaluate emission allowances for impairment if events or changes in circumstances indicate that they will not or cannot be used in operations. Prior to 2010, Ameren, Ameren Missouri and Genco expected to use their SOemission allowances for ongoing operations. In July 2010, the EPA issued the proposed CSAPR, which would restrict the use of existing SOemission allowances. As a result, Ameren, Ameren Missouri and Genco no longer expected all of their SO emission allowances would be used in operations.
Therefore, during 2010, Ameren, Ameren Missouri and Genco recorded an impairment charge to reduce the carrying value of their SO emission allowances to their estimated fair value. Ameren's and Genco's noncash pretax impairment charge was $68 million and $41 million, respectively. Ameren Missouri recorded a $23 million impairment of its SO emission allowances by reducing a previously established regulatory liability relating to SO emission allowances. Therefore, the Ameren Missouri SO emission allowance impairment had no impact on earnings. The fair value of the SOemission allowances was based on observable and unobservable
inputs. In July 2011, the EPA issued CSAPR, which created new allowances for SO and NO emissions, and restricted the use of pre-existing SOand NO allowances to the acid rain program and to the NO budget trading program, respectively. As a result, observable market prices for existing emis sion allowances declined materially. Consequently, during 2011, Ameren and Genco recorded a noncash pretax impairment charge of
$2 million and $1 million, respectively. Ameren Missouri recorded a $1 million impairment of its SO emission allowances by reducing a previously established regulatory liability relating to the SOemission allowances, which had no impact on earnings.

(a)Evaluation of Disclosure Controls and Procedures Table of ContentsManagement is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision of and with the participation of management, including the principal executive officer and principal financial officer, an evaluation was conducted of the effectiveness of each of the Ameren Companies' internal control over financial reporting based on the framework in InternalControl - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). After making that evaluation
,management concluded that each of the Ameren Companies' internal control over financial reporting was effective as of December 31, 2011. The effectiveness of Ameren's internal control over financial
reporting as of December 31, 2011, has been audited by Pricewaterhouse Coopers LLP, an independent registered public accounting firm, as stated in its report herein under Part II, Item 8. This annual report does not include an attestation repor tof Ameren Missouri's, Ameren Illinois' or Genco's (the Subsidiary Registrants) independent registered public accounting firm regarding internal control over financial reporting. Management's report for each of the Subsidiary Registrants is not subject to attestation by the independent registered public accounting firm. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness into future periods are subject to the risk that internal controls might become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures might deteriorate. There has been no change in the Ameren Companies' internal control over financial reporting during their most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, their internal control over financia lreporting. The Ameren Companies have no information reportable under this item that was required to be disclosed in a report on SEC Form 8-K during the fourth quarter of 2011 that has not previously been reported on an SEC Form 8-K.
