N N \\I\\I\\ \\l DEAR SHAREHOLDER Dramatic and successful. Strong nords, but they accurately reflect the results of1997.

l i

For the past two y ears, in my annual letter to you, I have discussed changes expected in the industry and the company as a result of deregulation of energy supply. Now it has happened. Your company has emerged from the uncertainty of the past in a strong position for future success. But 1997 was more, much more, than the culmination of the anticipated changes in energy markets. It marked, as well, a significant change in our core business of generating electricity, with the decision to sell our oil and natural gas power plants.

Perhaps most importantly, as it relates to our future, our employees went the extra mile throughout the year for our customers and for you, our shareholders. The results speak for themselves:

Total shareholder return was 51 percent as the company's share price climbed 41 percent.

Earnings per share increased to 52.71.

Field operations were redesigned around customer expectations, resulting in significant productivity and service improvements.

Nearly a doien new customer services were introduced.

1 egislation passed that assures customers of energy savings and choice of energy suppliers, w hile providing for full recerery of stranded costs.

Sale of our oil and gas fired power plants attracted a 50 percent premium.

These results alone are impressive. However, by themselves they mask the fact that the sale of our power plants makes us a smaller company. While we have exited the electric generation business, we are in an excellent position to pursue new opportunities for growth. We have adopted an ambitious vision of the future. We see a company with two million customers in the year 2000, a three fold increase in three years. That growth will come from a combination of geographic expansion in electricity delisery, and possibly gas delivery, and from our joint sentures.

l Ours is a vision that capitali7es on the restructuring of energy markets, as well as their convergence with telecommunications markets. That sision, and steps already taken to achiese it, prompted McGraw-liill Publishing's Electricallibrid magazine to award your company the 1997 James 11.

l McGraw Award for Corporate Excellence. The award was presented because of "the company's visionary restructuring and diversification efforts"and"its groundbreaking corporate strategy." As the award notes, the strategy " continues to strengthen the company's commitment to the end user" This report is about that commitment and about the employees who make it real.

s People and technology are coming together to change public policy and create competition in what had been a completely regulated monopoly industry. At Boston Edison, people and technology are also coming together - working together - to make a difference in delivering comfort, convenience and efDciency to customers. Boston Edison and the reliable delivery of electricity will be the core of the new holding company, BEC Energy.

In 1997, all aspects of the electric delivery business underwent transformation. Key business activities, such as electric system construction and services, asset management, metering and all aspects of customer care, were restructured around customer recluirements and the processes necessary to meet them.

The new business processes capture the best practices of workbclass companies, domestic and foreign.

This transformation is the result of a highly disciplined, customer-focused, strategic assessment of process, people and technological needs for a high performing " delivery" business.

To make the processes work, multi-disciplined teams are in place throughout Boston Edison. Separately, an asset management team focuses on investment planning and technology selection to ensure that the delisery network provides a high level of performance to achiese customer satisfaction and Gnancial return.

Meanwhile, new customer senice initiatives base been built around the principle of ease of doing business.These initiatives give customers options, and provide accurate and timely information and personalized service. New services intnxluced in 1997 included dired payment, Internet access to account information, appointment scheduling, and consolidated billing for customers uith multiple accounts. Also A new loolr introduced was a new storm response management and information system.This new system will shorten for the restoration time and provide customers with better information about restoration progress.

Boston As the changes described above were being implemented, major work continued to Edison upgrade the existing distribution system in and around the City of Boston. We also mtroduced a majorbili provides expansion of our automated meter reading system and further improvement in our remote monitoring customers and switching capabilities. Both significantly improve productivity and customer information, with more detailed infor-mation in an easier to read format.

N+N+NN WHAT CUSTOMERS CAN EXPECT FROM ELECTRIC UTILITY DEREGULATION Thefollowing is some basic information Bv. on Edison has been providmg its cunomers about deregulation, whic started March 1,1998.

Why was March I important?

Hat was when the production of electricity was officially" deregulated." That means that power pbnts will no longer be part of the regulated monopoly customers have known for decades. The electric utility, such as Boston Edison, will still deliver the electricity. But it will act more like Federal Express -- delivering the package of power you will purchase from among an array of producers. March I was also the date when electric utility rates -- the cent-per-kilowatt hour price -- went down 10 percent.

Does that mean the bill will go down 10%?

The price per kilowatt-hour will go down. Customers who use the same amount in March as during an earlier month, will see a 10 percent reduction. But consumption varies due to many factors, including weather, which affects the total bill. It is important to look at both the rate and the usage.

Will customers actually have to decide where to buy their electricity?

N, n t initially. They may choose to do nothing, to just continue getting power --

customers wiii production and delivery -- from the utility. The utility may not be producing it, but it will buy it for be able to choose the customers during the transition from monopoly to full competition.

Who will be responsible for ensuring a reliable supply of electricity?

result of market forces - supply and demand. Already,in anticipation of pending competition, power producers have announced new plants to meet anticipated demand for lower priced power.

STRENGTHENING THE ECONOMY AND THE COMMUNITY -- EQUALLY IMPORTANT Civic invoirement and emironmental stewardship remain an important aspect ofBoston Edison Companfs activities. The changes occurring in the electric utihty industry do not diminish the importance ofa nbrant economy, a clean ennronment and healthy communities to the well being of the company, its customers and its emplovces.

Over the years, the company has been active in programs to help the economy and the communities in which it does business. In 1997, the company continued to woil with state and local governments on quality oflife issues. For example, Chairman, President and CEOTom May chairs the Governor's Council on Economic Growth and Technology.The focus last year was on three issues -

in July 1997150ston Edison linalized its deregulation settlement agreement uith the Massachusetts Attorney General, the Massachusetts Disision of Energy Resources and various customer and environmental groups. Implementation of the settlement required state legislation and appnwal by the Massachusetts Department telecommunications and Energy (DTE). Iloth have been achiesed. The Massachusetts legislature passed, by overw helming majorities in both llouses, legislation that implements customer choice and competition for energy supply beginning in March 1998. " Landmark"may be an overused word to describe significant events. In this case,it seems appropriate.

The legislation is a well balanced approach to meeting the needs of customers, stm khohlers, communities hmting power plants and our employees. It assures all customers of a 10 percent rate reduction in 1998 followed by a further five percent reduction by September 1,1999. It prmides for full recovery of stranded costs w hile prmiding incentises for mitigating those costs. This is discussed more fully in the scetion on divestiture. Communities with power plant sites are protected against property tax losses as power plants are revalued. Additionally, the legislation maintains the state's commitment to those customers in need of assistance and to the deployment of energy conservation measures and the use of renewable energy.

The steps necessary to implement the legislation are now being taken. The company worked toward that end for much of 1997.113 year-end, sirtually all internal sy stems and infrastructure needed to implement customer choice were in place.

These inter nal changes were mming in concert with regulatory proceedings beli>re the DTE.

Employees worked The DTE considered specific filings from lloston Edison on the settlement and establishment of the through-holding company,13EC Energy. It also had to consider and act on new terms and conditions for

,,,3997 customers and for energy suppliers and registration requirements for suppliers and marketers. The DTE to pre.

Sithe Energies won the bidding, pasing a total of $657 million. Against a book salue of $450 million, Sithe's bid prosided 55 % milhon for the assets at fisc generating sites in and near lloston and s121 million for a transition purchase power contract.

Sithe cited competition and the recenth passed legidation as the reasons for its interest in I

hlassathusetts. Indicalise of how it sicu s the new market, Sithe also annouraed that it wouhl imest more than 51 billion at the sites to build 2,800 megawatts of new, highly eflicient generating capacity while keeping the 2,000 megan atts it purchased operating. This is testimont to our empimees and to the position $1 massachusetts has staked out in restructuring.

RCN's overall customer count totaled approximately 20,000 by the end of 1997. It has attracted intense interest from communities throughout Greater lloston and around the state, especially regarding its cable television service. This is largely because for the first time established cable television companies are running into direct competition. An often-cited example is the City of Somenille, next to Iknton. In that city,Tme Warner chose not to impose a 10 percent rate increase last fall, simply because of the competition from RCN. Other cities and towns are taking notice, and RCN is signing video agreements with communities at the rate of one per month.

EnergyVision, an energy marketing joint venture withThe Williams Companies ofTulsa, Oklahoma, showed modest growth in 1997, primarily in the natural gas market. The electricity market in l

New England did not develop as quickly as anticipated. This is expected to change, howner, as states such j

l as Massachusetts open their markets, and independent generating companies such as Sithe Energies deselop new projects.

challenges of deregulation come opportunities for growth. In 1998, we expect to see the beginning of Edison dramatic changes in the structure of the utility indnstry in New England.

Not:s to Consolidated Financial Statements Note A. Nature of Operations Boston Edison Company (the Company) is an investor-owned regulated public utility operating in the energy, energy services and telecommunications business. This includes the generation, purchase, transmission, distribution and sale of electric energy and the development and implementation of electric demand side management programs. A portion of our generation is produced by our wholly owncd nuclear generating unit, Pilgrim Nuclear Power Station. We supply electricity at retail to an area of 590 square miles, including the city of Boston and 39 surrounding cities and towns. We also supply electricity at wholesale for resale to other utilities and municipal electric depanments. Electric operating revenues were 88% retail and 12% wholesale in 1997. We also conduct unreg-ulated activities through our wholly owned subsidiary, Boston Energy Technology Group (BETG).

Through BETG and its subsidiaries, we are engaged in certain nonutility businesses, including energy utilization and conserva-tion, construction management and district energy. BETG has a joint venture with RCN Telecom Services, Inc. (RCN) that provides certain telecommunications-related services. The limited liability company (LLC) formed from this joint venture is owned 51% by RCN and 49% by BETG, with RCN having the day-to-day management responsibility. BETG also has a joint venture with Williams Energy Services Company (WESCO). This joint venture markets electricity, natural gas and energy-related services to retail customers in the six New England states. BETG and WESCO cach own 50% of this LLC, EnergyVision.

We are currently awaiting a decision from the Massacimsetts Department telecommunications and Energy (DTE), fonnerly the Department of Public Utilities, regarding our plan to form a holding company structure. This structure will clearly separate our regulated and unregulated lines of business. Through our holding company, BEC Energy, we will seek ways to expand our customer base. After the corporate reorganization, Boston Edison will be a wholly owned subsidiary of BEC Energy. BETG will cease being a subsidiary of Boston Edison and become a wholly owned subsidiary of BEC Energy. The common shareholders of Boston Edison will become shareholders of BEC Energy. The existing debt and preferred stock of Boston Edison will remain obligations of the regu-10ted utility business.

Refer also to Note C to these Consolidated Financial Statements for changes in the nature of our operations as a result of the electric utility industry restructuring and our related settlement agreement.

Note B. Significant Accounting Policies

1. Basis of Consolidation and Accounting The consolidated financial statements include the activities of our wholly owned subsidiaries, Harbor Electric Energy Company (HEEC) and BETG. All significant intercompany transactions have been eliminated. Certain reclassifications have been made to the prior year data to conform with the current presentation.

We follow accounting policies prescribed by the Federal Energy Regulatory Commission (FERC) and the DTE. We are also sub-ject to the accounting and reporting requirements of the Securities and Exchange Commission. The consolidated financial statements conform with generally accepted accounting principles (GAAP). As a rate-regulated company we have been subject to Statement of Financial Accounting Standards No. 71, Accounting for the Effects of Certain Types of Regulation (SFAS 71), under GAAP. The application of SFAS 71 results in differences in the timing of recognition of certain expenses from that of other businesses and indus-tries. As a result of the recently passed Massachusetts electric industry restructuring legislation and the DTE order regarding our related settlement agreement, as of December 31,1997, we are no longer applying the provisions of SFAS 71 to our generation busi-ness. Our distribution business remains subject to rate-regulation and continues to meet the criteria for application of SFAS 71.

Refer to Note C to these Consolidated Financial Statements for more information on the accounting implications of the electric utili-ty industry restruc.uring.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

2. Revenues We record estimates of retail base revenues for electricity used by our customers but not yet billed at the end of each accounting period.
3. Forecasted Fuel and Purchased Power Rates The rate charged to retail customers for fuel and purchased power allows for fuel and purchased power costs which are not included in our base rates to be billed to customers using a forecasted rate. The difference between actual costs and the amounts bilkd to cus-tomers is recorded as an adjustment to fuel and purchased power expenses and is included in accounts receivable on the consolidated balance sheer until subsequent rates are adjusted.

i a6

4. Utility Plant Utility plant is stated at original cost of construction. The costs of replacements of property units are capitalized. Maintenance and repairs and replacements of minor items are expensed as incurred. The original cost of property retired, net of salvage value, and the related costs of removal are charged to accumulated depreciation.
5. D:preciation and Nuclear Fuel Amortization Depreciation of our utility plant is computed on a straight-line basis using composite rates based on the estimated useful lives of the various classes of property. Excluding the effect of the adjustment discussed below, the overall composite depreciation rates were l

3.30%,3.33% and 3.28% in 1997,1996 and 1995, respectively.

Upon the completion of a review of our electric generating units, we determined that our oldest and least ef6cient fossil units (Mystic 4,5 and 6) were unlikely to provide competitively-priced power beyond the year 2000. Therefore we revised the estimated remaining economic lives of these units to five years in 1996.

The cost of decomshioning Pilgrim Station is excluded from our depreciation rates. Refer to Note E to these Consolidated Financial Statements for a discussion of nudear decommissioning. The cost of nudear fuel is amortized based on the amount of energy Pilgrim Station produces. Nudear fuel expense also indudes an amount for the estimated costs of uhimately disposing of spent nuclear fuel and for assessments for the decontamination and decommissioning of United States Department of Energy nudear enrichment facilities. These costs are recovered from our customers through fuel rates.

6. Deferred Nuclear Outage Costs We defer the incremental costs associated with nuclear refueling outages when incurred and amortize them over Pilgrim Station's oper-ating cycle. In 1995 we changed the amortization period from five years to two years. The two-year amortization period is consistent with the two-year cycle between nuclear refueling outages at Pilgrim Station.
7. Costs Associated with issuance and Redemption of Debt and Preferred Stock Consistent with our recovery in electric rates, we defer discounts, redemption premiums and related costs associated with the redemp-tion and issuance oflong-term debt and preferred stock. The costs related to long. term debt are recognized as an addition to interest expense over the life of the original or replacement debt. Beginning in 1996, consistent with an accounting order received from the FERC, we reflect costs related to preferred stock r demptions and issuances as a direct reduction to retained earnings upcm redemption or over the average life of the replacement preferred stock series as applicable.
8. Allowance for Borrowed Funds Used During Construction (AFUDC)

AFUDC represents the estimated costs to finance utility plant constmcrion. In accordance with regulatory accounting, AFUDC is induded as a cost of utility plant and a reduction of current interest charges. Although AFUDC is not a current source of cash income, the costs are recovered from customers over the service life of the related plant in the form ofincreased revenues collected as a result of higher depreciation expense. Our AFUDC rates in 1997,1996 and 1995 were 6.04%,5.87% and 6.35%, respectivdy, and represented only the cost of short-term debt.

9. Cash and Cash Equivalents Cash and cash equivalents are comprised of highly liquid securities with maturities of 90 days or less when purchased. Outstanding checks are included in cash and accounts payable until they are presented for payment.
10. Allowance for Doubtful Accounts Our accounts receivable are substantially recoverable. This recovery occurs both from customer payments and from the portion of cus-tomer charges that provides for the recovery of bad debt expense. Accordingly, we do not maintain a significant allowance for doubtful accounts balance.
11. Regulatory Assets Regulatory assets represent costs incurred which are expected to be collected from customers through future charges in accordance with j

agreements with our regulators. These costs are expensed when the corresponding revenues are received in order to appropriately j

match revenues and expenses. The majority of these costs is currently being recovered from customers over varying time periods. Refer

12. Eirnings Per Share of Common Stock Basic earnings per share (EPS) of common stock is calculated by dividing net income, after the payment of preferred stock dividends, by the weighted average common shares outstanding during the year. Statement of Financial Accounting Standards No.128, Earnings per Share, requires the disclosure of diluted EPS effective for periods ending after December 15,1997.1)iluted EPS is similar to the computation of basic EPS except that the weighted average common shares is increased to include the number of dilutive potential common shares. Diluted EPS, which indudes the effect of deferred (nonvested) shares and stock options granted under the Stock Incentive Plan in the calculation of weighted average common shares, is the same as basic EPS displayed on the consolidated statement of income.

Note C. Electric Utility industry Restructuring

1. Accounting implications Under the traditional revenue requirements model, our electric rates have been based on the cost of providing electric service. As such, we have been subject to certain accounting standards that are not applicable to other businesses and industries in general. The applica-tion of SFAS 71 requires us to defer the recognition of certain costs when incurred if future rate recovery of these costs is expected.

Based on a consensus reached by the Emerging Issues Task Force (EITF) regarding specific issues raised related to the application of SFAS 71, we have determined that, as of December 31,1997, the provisions of SFAS 71 no longer apply to the generation portion of our busi-ness. In its consensus, the EITF determined that when deregulation legislation is passed and regulatory actions have taken place provid-ing sufficient detail for an enterprise to reasonably determine how the transition plan will affect the separable portion cfits business being deregulated, the enterprise should stop applying SFAS 71 to that portion ofits business. On January 28,1998, the DTE approved our restructuring settlement agreement that was filed in July 1997. The DTE found that the settlement agreement substantially com-plied or was consistent with key provisions of a Massachusetts law enacted in November 1997 establishing a comprehensive framework for the restructuring of our industry. The EITF further determined that book values of assets and liabilities originating in the separable portion of the business no longer subject to rate-regulation should be evaluated on the basis of where the regulated cash flows to realize and settle them will be derived. Net utility plant and other related assets on our consolidated balance sheet as of L)ecember 31.1997 include approximately $700 million related to nuclear generation and approximately $450 million related to fossil generation. As part of our settlement agreement, approximately 75% of these nuclear assets are fully recoverable through the non-bypassable transition charge of our distribution business which continues to be subject to rate-regulation. The remaining 25% will be collected under Pilgrim's wholesale life of the unit contracts. These contracts continue to be regulated by the FERC and are not impacted by our settlement agree-ment. These fossil assets will be recovered from the proceeds from their sale as discussed in part 2 below.

The implementation of our approved settlement agreement has certain accounting implications. The highlights of these include:

D:pr:clation The composite depreciation rate for distribution utility plant increases from 2.38% to 2.98% as of March 1,1998 (the retail access date).

G:noration related plant and regulatory assets Plant and regulatory assets related to our generation business, except for those related to Pilgrim's wholesale life of the unit contracts, will be recovered through the transition charge. This recovery, which includes a return, will occur over a twelve-year period, aR

}

Storm fund i

Under the settlement agreement, we are authorized to establish a storm contingency fund to use for the incremental costs of any major storm (in mess of $1 million). The settlement required that we initially establish the fund with $8 million of proceeds received from l

the sale of Clean Air Act emission allowances. As costs are charged against the fund, the balance will be restored to the original level from distribution charges up to a maximum of $3 million per year.

Fu:I and purchased power charge The fuel and purchased power charge ceases as of the retail access date. Net remaining over or under collection of fuel and purchased power cons will be reflected in future customer billings.

Stzndard offer charge l

Customers will have the option of continuing to buy power from our electric delivery business at " Standard Offer" prices as of the retail access date. The Standard Offer charge begins at 2.8 cents at retail access and increases to 5.1 cents by 2004. The cost of provid-ing Standard Offer service, which includes fuel and purchased power costs, will be recovered from Standard Ofrer customers on a fully 9

reconciling basis.

j Distribution and transmission charges l

Distribution rates will be subject to a minimum and maximum return on average common equity (ROE) through December 31,2000.

The ROE is subject to a floor of 6% and a ceiling of 11.75%. If the ROE is below 6%, we are authorized to add a surcharge to distri-i bution rates in order to achieve the 6% floor. If the ROE is above 11%, we are quired to adjwt distribution rates by an amount nec-cssary to reduce the calculated ROE between 11% and 12.5% by 50%, and a wmrn above 12.5% by 100%. No adjustment is made if I

the ROE is between 6% and 11%. In addition, distribution rates will be adjusted for any changes in tax laws or accounting principles that result in a change in our costs of more than $1 million. The cost of providing transmission service to distribution customers will be recovered on a fully reconciling basis.

NucI:ar generation Under the settlement agreement, the annual performance adjustment charge ceases and our cost recovery mechanism for Pilgrim Station changes as of the retail access date. Approximately 25% of the operations and capital costs, including a return on investment, will continue to be collected under wholesale life of the unit contracts. The remaining output will be sold in the competitive energy market. Through December 31,2000, we will share 25% of any profit or loss from the sale of Pilgrim's output with distribution customers through the transi-

)

tion charge. In addition, we will obtain transition payments up to a maximum of $23 million per year depending on the level of costs

{

incurred for property taxes, insurance, regulatory fees and security requirements.

J Nucl:ar decommissioning Approximately 25% of Pilgrim's decommissioning costs will continue to be collected under wholesale life of the unit contracts. The remaining portion will be recovered through the transition charge. Amounts collected for decommissioning will be adjusted as decom-missioning cost studies are updated. Refer to Note E to these Consolidated Financial Statements for more information on nuclear decommissioning costs.

2. Divestiture of Fossil Generating Assets l

Included in our settlement agreement is a provision for the divestiture of our fossil generati. g assets. On December 10,1997,we entered into a purchase and sale agreement with Sithe Energies, Inc., a privately-held compa.y headquartered in New York, to purchase our non-nuclear generating assets. The proceeds from the sale of these assets will be $657 million. The net book value of these assets at December 31,1997 is approximately $450 million, included in the purchase price, Sithe Energies will pay $121 million to us in connection with a six-month transitional power sales agreement under which we will continue to buy power from the generating l

plants. Sithe Energies will aho be responsible for obligations resulting from the recently enacted utility restructuring legislation for property tax payments to communities with non-nuclear power plants.

In July 1997, we reached an agreement with our field service union that requires the buyer of our fossil generating assets to rec-l ognize and continue to honor the provisions of the union's current collective bargaining agreemem through the end ofits term May 2000. As part of a package offered to employees affected by the fossil divestiture, all eligible fossil and designated fossil support employees age 55 or older with at least 10 years of service, or age 65 by July 1,1998, were offered unreduced retirement and transi-tion benefits under a voluntary early retirement program (VERP). Under this program,40 people c!ected to retire. Retirement dates are expected to be the first of the month following the transfer of ownership of our fossil generating assets. Severance programs were offered to management and field service union employees afTected by the fossil divestiture that did not elect or were ineligible to retire under the VERP. These severance benefits include salary payments, education / retraining allowances and outplacement services. It is anticipated that 48 employees will receive severance benefits under these programs.

29

The estimated costs associated with the VERP and severance programs is approximately 521 million including the effects on the retirement, life and dental plans. Severance and employee retraining costs related to the divestiture are recoverable through the d bution transition charge under our settlement agreement. Therefore, we have established an offsetting regulatory asset for the ations on our consolidated balance sheet at December 31,1997.

3. Nuclear Asset Impairment As part of the settlement agreement, we recover our net investment in Pilgrim Station as of December 31,1995 (adjusted fo tion through 1997) through the distribution transition charge. Under the terms of the settlement agreement, we must perform a ma ket valuation of Pilgrim by 2002. Upon acceptance of the valuation by the DTE, the resulting dollar amount, net of prudently incurred post-1995 investments in the plant, will reduce amounts collectible through the transition charge. If the valuation is not s cient to allow for the recovery of these investments, we will seek their recovery through the transition charge. Due to the market pres-sures facing us, the ultimate recovery of these assets is not certain. Therefore, we reduced our investment in Pilgrim by the 513 m invested in the plant since January 1,1996 as an impairment loss under Statement of Financial Accounting Standards No.121, Accounting for the Impairment oflong-Lived Assets and for Long-Lived Assets to Be Disposed Of(SFAS 121). An after tax charge o approximately $8 million due to this reduction was recorded to non-operatirg expense on our consolidated statement ofincome in fourth quarter of 1997. A similar uncertainty does not exist for the ultimate recovery of the fossil generating assets as the sale proceed agreed to in the purchase and sale agreement with Sithe Energies exceeds the net book value of these assets.

Note D. Income Taxes Income taxes are accounted for in accordance with Statement of Financial Accounting Standards No.109, Accounting for Income Taxes (SFAS 109). SFAS 109 requires the recognition of deferred tax assets and liabilities for the future tax effects of temporary differ-ences between the carrying amounts and the tax basis of assets and liabilities. In accordance with SFAS 109 we recorded net regulatory i

assets of $51.1 million and $47.5 million and corresponding net increases in accumulated deferred income taxes as of December 31, 1997, and December 31,1996, respectively. The regulatory assets represent the additional future revenues to be collected from cus-tomers for deferred income taxes.

Accumulated deferred income taxes consisted of the following:

Note E. Nuclear Decommissioning and Nuclear Waste Disposal 1 Nuclear Decommissioning When Pilgrim Station's operating license expires in 2012 we will be required to decommission the plant. Decommissioning means to remove nuclear facilities from service safely and reduce residual radioactivity to a level that permits termination of the Nuclear Regulatory Commission (NRC) license and release of the property for unrestricted use. We record an estimate of decommissioning costs in depreciation expense on the consolidated statements ofincome over Pilgrim's expected service life. Decommissioning expense is approximately $14 million per year. The estimate used to determine our annual expense is based on a 1991 study that documents a cost of approximately $328 million to decommission the plant using the " green field" method, which provides for the plant site to be com-pletely restored to its original state. The cost estimate was incorporated in our 1992 retail settlement agreement. We receive recovery of the annual expense through charges to our retail customers and from other utility companies and municipalities which purchase a con-tracted amount of Pilgrim's electric generation. The funds we collect from decommissioning charges are deposited in an external trust and are restricted to use for decommissioning and related expenses. The net earnings on the trust funds, which are also restricted,

-increase the nuclear decommissioning trust balance, thus reducing the amount to be collected from customers.

l The 1991 decommissioning study was partially updated for internal planning purposes in order to evaluate the potential impae of long-term spent fuel storage options resulting from delays in the United States Department of Energy (DOEJ spent fuel removal pro-gram. Refer to part 2 for a discussion of spent fuel removal. The partial update indicated an estimated decommissioning cost of $400 million in 1991 dollars based upon a revised spent fuel removal schedule and utilization of dry spent fuel storage technology. We are in the process of updating this study. No final cost estimate is currently available; however, we continue to monitor DOE spent fuel removal schedules and developments in spent fuel storage technology along with their impact on the decommissioning estimate.

Cenain financial reporting considerations related to nuclear decommissioning costs have not been fully resolved. In 1996 the i.

Financial Accounting Standards Board (FASB) issued proposed new rules for accounting for liabilities related to closure and removal of long-lived assets, which include decommissioning of nuclear generating facilities. If these proposed rules are adopted we would be required to retroactively recognize the entire estimated liability for decommissioning costs on the balance sheet, offset by an addition to utility plant. The plant addition would be depreciated over Pilgrim's remaining expected service life. The liability would be mea-sured based on the prosent value of estimated future cash flows. The cumulative effect of adoption of these proposed rules could result 1 in the recognition of a regulatory asset to be recovered from customers to the extent that the present value difference in the liability between when the liability was incurred and when the rules are adopted exceeds the depreciation expense previously recognized for decommissioning. In addition, trust fund earnings would be eported on the income statement. The FASil recently resumed its delb

- erations on this project. No date has been set for the issuan c f either a final statement or revised proposed m!<

2. Spent Nucinr Fusi The verit fuel storage facility at Pilgrim Station is expected to provide storage capacity through approximately 2003. We have a license amendment from the N81C to modify the facility to provide suflicient room for spent nuc! car fuel generated through the end of Pilgrim's operating licere 'n 2012t however, any further modifications are subject to review by the DTE. We are actively exploring the feasibility of other spent a el storage facilities and technologies.

Delays in identifying a permanent storage site have continually postponed plans for the DOE's long-term storage and disposal I

site for spent nuclear fuel. The DOE's current estimate for an available site is 2010. In November 1997, the U.S. Court of Appeals for the District of Columbia Circuit ruled that the lack of an interim storage facility does not excuse the DOE from meeting its con-tract obligation to begin accepting spent nuclear fuel no later than January 31,1998. This decision was in response to petitions filed by us and other interested parties seeking declaratory rulings concerning enforcement and remedies for the DOE's failure to accept j

spent fuel in a timely manner. The court directed the plaintiffs to pursue relief under terms of their contracts with the DOE. Based on this ruling, the DOE may have to pay contract damages ifit does not take the spent nuclear fuel as scheduled. Under the Nuclear Waste Policy Act of 1982, it is the ultimate responsibility of the DOE to permanently dispose of spent nuclear fuel. We currently pay a fee of $1.00 per net megawarthour sold from Pilgrim Station generation under a nuclear fuel disposal contract with the DOE. The fee is collected from customers through fuel charges. We cannot predict at this time whether or on what schedule the DOE will eventually construct a spent fuel repository or what the effect will be of any delays in such construction.

The DOE recently denied our petition to suspend payments made to the Nuclear Waste Fund based on its interpretation of the U.S. Court of Appeal's decision made in November 1997. The DOE has, however, made an offer to consider amendments to exist-ing contracts to address the hardships the anticipated delay in accepting spent fuel may cause individual contract holders. We contin-ue to monitor this situation and consult with legal counsel as to our next course of action.

3. Low-Level Radioactive Waste We regained access to low-level radioactive waste (LLW) disposal facilities located in Barnwell, South Carolina, in 1995. This site is currently the only disposal facility available to us. legislation has been enacted in Massachusetts establishing a regulatory process for managing LLW, including the possible siting, licensing and construction of a disposal facility within the state, or, alternatively, an agree-ment with one or more other states. Pending the construction of a disposal facility within the state or the adoption by the state of some other LLW management procedure, we will continue to monitor the situation and investigate other anilable options.

Note E 1995 Corporate Restructuring in 1995 we streamlined the corporate organization and reorganized the company into separate business units in order to strengthen our competitiveness in the changing electric energy market. In conjunction with this reorganization we offered enhanced retirement pro-grams and implemented a special severance program to reduce employee staffmg levels. Under the enhanced retirement programs 330 employees elected to retire, and 149 employees whose positions were eliminated became eligible for benefits under the special severance program. These programs resulted in a $34 million pre-tax charge ($20.7 rnillion after tax) over the third and fourth quarters of 1995.

The charge consisted of $24 million for the retirement programs and $10 million for the severance program.

Note G. Pensions and Other Postretirement Benefits

1. P:nsions We have a defmed benefit funded retirement plan with certain contributory features that covers substantially all employees. Benefits are based upon an employee's years of service and highest eligible average compensation during the last ten years of credited employ-ment. Our funding policy is to contribute an amount each year that is not less than the minimum required contribution under federal law or greater than the maximum tax deductible a ount. The retirement plan assets consist of equities, bonds, money market funds, insurance contracts and real estate funds.

We also have an unfunded supplemental retirement plan for certain management employees. Benefits under this plan are based upon an employee's years of service and highest eligible average compensation during years of credited employment.

We experienced a high number of employee retirements from 1994 to 1996. A large number of these retirements were as a direct 3

I result of our 1995 corporate restructuring. In 1997, a review of the accounting for the pension expense related to the retirements revealed that an adjustment to the pension costs related to these employees was necessary. Therefore, we increased our pension regula-9 tory asset by $8.6 million in 1997 for the adjustment related to the period of our 1992 settlement agreement. The remaining adjust-ment did not have a material impact on our consolidated results of operations or financial position, j

2. Oth r Postretirement Benefits In addition to pension benefits, we also provide health care and other benefits to our retired employees who meet certain age and years of service eligibility requirements. These postretirement benefits other than pensions (PBOPs) are accounted for in accordance with Statement of Financial Accounting Standards No.106, Employers' Accounting for Postretirement Benefits Other Than Pensions (SFAS 106). Our 1992 retail rate settlement agreement provided us with a phase-in to full expense of the PBOP costs incurred under SFAS 106. This settlement agreement allowed us to defer any costs in excess of the specified phase-in amounts to the extent that we funded an external trust. Our funding policy is to generally contribute 100% of PBOP costs to external trusts. Therefore, we recognized $23 mil-lion of PBOP costs in 1995 in accordance with the 1992 settlement agreement. Beginning in 1996 we recognized the full PBOP costs incurred under SFAS 106. The net deferred PBOP costs of $15 million resulting from the delayed phase-in are included in regulatory assets as thee costs will be recovered from customers in future periods.

The weighted average discount rates used to measure the program's year-end funded status were 7.25% in 1997 and 7.75% in 1996. The trust assets consist of equities, bonds and money market funds.

Note H. Stock-Based Compensation in 1997, we initiated a Stock Incentive Plan (the Plan) which was adopted by the Board of Directors and approved by our stockholders.

The Plan permits a variety of stock and stock-based awards, including stock options and deferred (nonvested) stock to be granted to cer-t2in key employees. The Plan limits the terms of awards to ten years. Subject to adjustment for stock-splits and similar events, the i

aggregate number of shares of common stock that may be delivered under the Plan is 2,000,000, including shares issued in lieu of or upon reinvestment of dividends arising from awards. During 1997, we granted 73,820 shares of deferred stock and 298,400 ten-year non-qualified stock options under the Plan. The weighted average grant date fair value of the deferred stock is $27.26. The options were granted at the full market price of the stock on the date of the grant. Both awards vest ratably over a three-year period.

We recognize compensation cost for our stock-based awards under the provisions ofAPB Opinion 25, which requires compensation cost to be measured by the quoted stock market price at the measurement date less the amount, if any, an employee is required to pay.

1. Long-tsrm Dsbt The 9 7/8% debentures due 2020 are first redeemable in June 2000 at a redemption price of 104.483%, the 9 3/8% series due 2021 are l

first redeemable in August 2001 at 104.612%, the 8.25% series due 2022 are first redeemable in September 2002 at 103.780% and the 7.80% series due 2023 are first redeemable in March 2003 at 103.730%. No other series are redeemable prior to maturity. There is no sinking fund requirement for any series of our debentures.

Sewage facility revenue bonds were issued by HEEC. The bonds are tax-exempt, subject to annual mandatory sinking fund redemption requirements and mature through 2015. In both May 1996 and 1997, we redeemed $1.6 million as scheduled. The weighted average interest rate of the bonds is 7.3%. A portion of the proceeds from the bonds is in reserve with the trustee. If HEEC should have insufficient funds to pay for extraordinary expenses, we would be required to make additional capital contributions or loans to the subsidiary up to a maximum of $1 million.

The 5.75% tax-exempt unsecured bonds due 2014 are redeemable beginning in February 2004 at a redemption price of 102%.

The redemption price decreases to 101% in February 2005 and to par in February 2006.

In March 1997, we obtained $100 million of 6.662% notes in the form of a bank loan. This note matures in 1999.

The aggregate principal amounts of our long-term debt (including HEEC sinking fund requirements) due through 2002 are 5101.6 million in 1998 and 1999, $166.6 million in 2000 and $1.6 million in 2001 and 2002.

2. Short-term Debt We have arrangements with certain banks to provide short-term credit on both a committed and an uncommitted and as available basis. We currently have regulatory aethority to issue up to $350 million of short-term debt.

We have a $200 million revolving credit agreement with a group of banks. This agreement is intended to provide a standby source of short-term borrowings. Under the terms of this agreement we are required to maintain a common equiry ratio of not less than 30% at all times. Commitment fees must be paid on the unused portion of the total agreement amount.

Information regarding our utility short-term borrowings, comprised of bank loans and commercial paper, is as follows:

Nots L. Commitm nts and Conting:ncies

1. Contractual Commitments At December 31,1997, we had estimated contractual obligations for plant and equipment of approximately $18 million.

We have leases for certain facilities and equipment. Our estimated minimum rental commitments under both transmission agreements and noncancellable leases for the years after 1997 are as follows:

(in thousands) l l

1998 21,938 l

1999 18,958 l

2000 16,738 2001 12,356 2002 11,194 Yurs thereafter 91,874 Total

$ 173,058 Amounts above include $2.7 million which is expected to be assumed by Sithe Energies as part of our pending fossil divestiture discussed in Note C to these Consolidated Financial Statements.

The total of future minimum rental income to be received under noncancellable subleases related to the above leases is $300,921.

We will capitalize a portion of these lease rentals as part of plant expenditures in the future. The total expense for both lease rentals and transmission agreements was $27.5 million in 1997, $26.3 million in 1996 and $24.5 million in 1995, net of capitalized j

expenses of $1.2 million in 1997, $2.9 million in 1996 and $2.7 million in 1995.

l We previously entered into various take or pay and throughput agreements, primarily to supply our New Boston fossil generating l

st2 tion with natural gas. The fixed and determinable portions of the obligations associated with these agreements are $19.5 million in 1998 and 1999 and $14.6 million in 2000. As part of our fossil divestiture agreement, Sithe Energies has agreed to assume these obligations. The total expense under these agreements was $47.1 million in 1997, $49.5 million in 1996 and $13.9 million in 1995.

2. Electric Company investments We have an approximately 11% equity investment in two companies which own and operate transmission facilities to import electricity from the Hydro-Quebec system in Canada. As an equity participant we are required to guarantee, in addition to our own share, the total obligations of those participants who do not meet certain credit criteria. At December 31,1997, our portion of these guarantees was $16.6 million.

We have a 9.5% equity investment of approximately $2 million in Yankee Atomic Electric Company (Yankee Atomic). In 1992 the board of directors of Yankee Atomic decided to discontinue operations of the Yankee Atomic nuclear generating station perma-nently and decommission the facility.

l Yankee Atomic received approval from the FERC to continue to collect its investment and decommissioning costs through 2000, the period of the plant's operating license. The estimate of our share of Yankee Atomic's investment and costs of decommissioning is approximately $13 million as of December 31,1997. This estimate is recorded on our consolidated balance sheet as a power contract liability and an offsetting regulatory asset.

We also have a 9.5% equiry investment in Connecticut Yankee Atomic Power Company (CYAPC) of approximately $11 million.

In December 1996, the board of directors of CYAPC, which owns and operates the Connecticut Yankee nuclear electric generating unit (Connecticut Yankee), unanimously voted to retire the unit. The decision was based on an economic analysis of the costs of operating the unit through 2007, the period ofits operating license, compared to the costs of closing the unit and incurring replace-ment power costs for the same period.

The current estimate of the sum of future payments for the closing, decommissioning and recovery of the remaining investment in Connecticut Yankee is approximately $615 million. Our share of these remaining estimated costs is $58 million. This estimate is recorded on our consolidated balance sheet as a power contract liability and an offsetting regulatory asser similar to Yankee Atomic.

In early 1997, CYAPC filed a rate case at the FERC seeking to recover certain post-operating costs, including decommissioning.

The Connecticut Department of Public Utility Control (DPUC) has raised concerns to _the FERC regarding CYAPC's estimate of these costs and the plant operator's prudency prior to the shutdown decision. The FERC set CYAPC's request for hearing before an Administrative Law Judge. The DPUC subsequently filed testimony in the proceeding asserting the position that the FERC should deny recovery of substantial post-operating costs, including a significant amount related to decommissioning and the return on CYAPC's undepreciated investment. We are currently unable to determine the ultimate outcome of this proceeding or its impact.

l 1 Nucinr Insurtnca The federal Price-Anderson Act currently provides $8.9 billion of financial protection for public liability claims and legal costs arising from a single nuclear-related accident. The first $200 million of nuclear liability is covered by commercial insurance. Additional nuclear liability insurance up to $8.7 billion is provided by a retrospective assessment of up to $79.3 million per incident levied on each of the 110 nuclear generating units currently licensed to operate in the United States, with a maximum assessment of $10 million per reactor per accident in any year.

We have purchased insurance from Nuclear Electric Insurance Limited (NEIL) to cover some of the costs to purchase replace-

)

ment power during a prolonged accidental outage and the cost of repair, replacement, decontamination or decommissioning of our utility property resulting from covered incidents at Pilgrim Station. Our maximum potential total assessment for losses which occur during current policy years is $10.4 million under both the replacement power and excess property damage, decontamination and decommissioning policies.

4. Hazardous Waste We are an owner or operator of approximately 30 propenies where oil or hazardous materials were spilled or released. As such, we are required to clean up these propenies in accordance with a timetable developed by the Massachusetts Depanment of Environmental Protection. We continue to evaluate the costs associated with site cleanup. There are uncenainties associated with these costs due to the comph.ities of cleanup technology, regulatory requirements and the particular characteristics of the different sites. We also contin-ue to face possible liability as a potentially responsible party in the cleanup of six multi-party hazardous waste sites in Massachusetts and other states where we are alleged to have generated, transported or disposed of hazardous waste at the sites. We are one of many potentially responsible panies and currently expect to have only a small percentage of the potential liability. Through December 31, 1997, we have accrued approximately $7 million related to our cleanup liabilities. We are unable to fully determine a range of reason-ably possible cleanup costs in excess of the accrued amount, although based on our assessments of the specific site circumstances, we do not believe that it is probable that any such additional costs will have a material impact on our financial condition. However, it is rea-sonably possible that additional provisions for cleanup costs that may result from a change in estimates could have a material impact on the results of a reporting period in the near term.
5. Generating Unit Performance Program Our recovery of the incremental purchased power costs resulting from outages at our generating units occurring through the retail access date is subject to review by the DTE. We are unable to fully determine a range of reasonably possible disallowance costs in excess of amounts accrued, although, based on the information currently available, we do not believe that it is probable that any such additional costs will have a material impact on our financial condition. However, it is reasonably possible that additional disallowance costs that may result from a change in estimates could have a material impact on the results of a reponing period in the near term.
6. Litigation In October 1997, the DTE operwd a proceeding to investigate our compliance with the 1993 order which permitted the formation of BETG and authorized us to invest up to $45 million in unregulated activities. We are unable to determine the ultimate outcome of this proceeding or its impact on our operations.

In the normal course of our business we are involved in certain other legal matters. We are unable to fully determine a range of reasonably possible litigation costs in excess of amounts accrued, although, based on the information currently available, we do not believe that it is probable that any such additional costs will have a material impact on our financial condition. However, it is reason-ably possible that additional litigation costs that may result from a change in estimates could have a material impact on the results of I

a reporting period in the near term.

7. Industry Restructuring Legal Proceedings / Referendum Campaign The DTE order approving our settlement agreement has been appealed by certain panies to the Massachusetts Supreme Judicial Court.

In addition, along with other Massachusetts investor owned utilities, we have been named as a defendant in a class action suit seeking to declare cenain provisions of the Massachusetts electric industry restructuring legislation unconstitutional. We are currently unable to determine the outcome of these proceedings or their impact on us.

j Opponents of the electric industry restructuring legislation that was enacted in November 1997 have mounted a referendum campaign to repeal that law. A coalition of business, industry and public interest groups that supported the legislation, along with the electric utility industry, is opposed to the referendum and is prepared to mount an aggressive campaign to defeat it. We are cur-rently unable to predict the eventual outcome of this referendum or its impact on us.

management programs.

Refer to the Electric Utility Industry Restructuring section of Item 7 for information regarding the restructuring of the electric utility industry and its impact on the Company.

The Company also conducts unregulated activities through its wholly owned subsidiary, Boston Energy Technology Group (BETG). Through BETG and its subsidiaries, the Company is engaged in certain nonutility businesses, including energy utilization and conservation, construction management and district energy.

Refer to Note A to the Consolidated Financial Statements in Item 8 for more information regarding the Company's nonutility business ventures.

The Company is currently awaiting a decision from the Massachusetts Department of Telecommunications and Energy (DTE), formerly the Department of Public Utilities, and the Securities and Exchange Commission regarding its reorganization plan to form a holding company structure. This plan has been e

approved by the Federal Energy Regulatory Commission (FERC), the Nuclear Regulatory Commission (NRC) and the Company'4 shareholders.

Refer to Note A to the Consolidated Financial Statements in Item 8 for more information regarding the holding company structure.

(b) Financial Information about Industry Segments The Company operates primarily as a regulated electric public utility, therefore industry segment information is not applicable.

(c) Narrative Description of Business Principal Products and Services The Company supplies electricity at retail to an area of 590 square miles, including the city of Boston and 39 surrounding cities and towns.

The population of the area served with electricity at retail is approximately 1.5 million.

In 1997 the Company served an average of approximately 660,000 customers. The Company also supplies electricity at wholesale for resale to other utilities and municipal electric departments.

Sources and Availability of Fuel The Company currently owns two stations whose generating units have the ability to burn oil, natural gas or both, one nuclear power station and ten combustion turbine generators. As discussed in Item 2, tho Company entered into an agreement to sell its non-nuclear generating assets in 1997.

Finalization of the sale is expected in mid-1998.

The Company's generation by type of fuel and the cost of fuel for each of the last five years were as follows:

Percentage of Company Average Cost of Fuel Generation by Source (%)

($ per Million BTU) 1997 1996 1995 1994 1993 1997 1996 1995 1994 1993 Oil 32.0 16.1 17.5 27.8 31.3 2.22 3.04 2.66 2.35 2.38 Gas 31.1 33.3 39.9 31.6 24.3 3.23 3.11 2.17 2.28 2.67 Nuclear 36.9 50.6 42.6 40.6 44.4 0.46 0.41 0.43 0.50 0.51 The majority of the Company's residual oil purchases consists of imported oil acquired primarily from international suppliers. Through March 1997, the Company had a contract with a major oil company to supply most of its estimated requirements.

The Company has been purchasing oil on the spot narket since that contract expired.

A portion of the Company's natural gas is supplied on an interruptible basis by contract. These contracts permit interruptions in deliveries by the supplier when natural gas supplies or pipeline capacity is unavailable. The Company 3, currently required to fuel New Boston Station exclusively by natural gas, except in certain emergency circumstances, as part of a 1991 consent order with the Massachusetts Department of Environmental Protection.

The Company has arrangements for a firm supply of natural gas to run the station at a minimum level and has a least-cout plan for operating beyond this ndnimum level which principally utilizes interruptible gas supplies or short-term capacity purchases.

In order to obtain fuel for use at its nuclear generating unit, the Company must obtain supplies of uranium concentrates and secure contracts for these concentrates to go through the processes of conversion, enrichment and fabrication of nuclear fuel assemblies. The Company currently has contracts l

for supplies of uranium concentrates and the processes of conversion, enrichment and fabrication through 2002, 2000, 2004 and 2012, respectively.

Franchises l

l Through its charter, which is unlimited in time, the Company has the right to engage in the business of producing and selling electricity, steam and other forms of energy, has powers incidental thereto and is entitled to all the rights and privileges of and subject to the duties imposed upon electric l

companies under Massachusetts laws. The locations in public ways for the l

Company's electric transudssion and distribution lines are obtained from municipal and other state authorities which, in granting these locations, act l

as agents for the state.

In some cases the action of these authorities is subject to appeal to the DTE.

The rights to these locations are not limited in time, but are not vested and are subject to the action of these authorities and the legislature.

Pursuant to the Massachusetts electric utility industry restructuring legislation enacted in November 1997, the DTE has defined the service territory of the Company based on the territory actually served on July 1, 1997, and following, to the extent possible, municipal boundaries.

The legislation further provided that, until terminnted by effect of law or 3

otherwise, the Company shall hava the exclusive obligation to provide distribution service to all retail customers within such service territory.

No other entity shall provide distribution service within this territory without the written consent of the Company which consent must be filed with the DTE and the municipality so affected.

Seasonal Nature of Business The Company's kilowatt-hour (kWh) sales and revenues are typically higher in the winter and summer than in the spring and fall as sales tend to vary with weather conditions.

In addition, the Company bills higher base rates to commercial and industrial customers during the billing months of June through September as authorized by the DTE.

Accordingly, greater than half of the company's annual earnings typically occurs in the third quarter.

Refer to the Selected consolidated Quarterly Financial Data (Unaudited) in Item 8.

Competitive conditions Refer ~to the Electric Utility Industry Restructuring section of Item 7 for a discussion of the competitive conditions affecting the Company.

Environmental Matters

~The Company is subject to numerous federal, state and local standards with respect to the management of wastes, air and water quality and other environmental considerations. These standards could require modification of existing facilities or curtailment or termination of operations at these facilities. They could also potentially delay or discontinue construction of new facilities and increase capital and operating costs by substantial amounts. Noncompliance with certain standards can, in some cases, also result in the imposition of monetary civil penalties.

Environmental-related capital expenditures for the years 1997 and 1996 were

$1.4 million and $2.7 million, respectively.

These expenditures are forecasted to be approximately $2 million in each of the years 1998 and 1999.

The Company believes that its operating facilities are in substantial compliance with currently applicable statutory and regulatory environmental requirements. Additional expenditures could be required as changes in environmental requirements occur.

Refer to the Environmental section of Item 7 for more information.

Number of Employees As of March 21, 1998, the Company had 3,196 full-time and 33 part-time utility employees including 2,166 represented by two locals of the Utility Workers Union of America, AFL-CIO.- The locals' labor contracts are effective through May of the year 2000. Wholly owned subsidiary operations had 27 full-time employees.

Employee relations are considered satisfactory by the company.

Refer to the Divestiture of Fossil Generating Assets section of Item 7 for information regarding employees affected by the sale of these assets.

(d) Financial Information about Foreign and Domestic Operations and Export Sales Refer to Principal Products and Services of this item for infonnation regarding the geographical area served by the Company and revenues by class for the last three years.

i (e) Additional Information Regulation The Company and its whelly owned subsidiary, Harbor Electric Energy Company (HEEC), operate primarily under the authority of the DTE, whose jurisdiction includes supervision over retail rates for electricity and financing and investing activities.

In addition, the FERC has jurisdiction over various phases of the Company's business including rates for Fawer sold at wholesale i

for resale, facilities used for the transmission or sale of that power, certain issuances of short-term debt and regulation of the system of accounts.

The Company's subsidiary BETG and its subsidiaries are not subject to such regulation.

The NRC has broad jurisdiction over the siting, construction and operation of l

nuclear reactors with respect to public health and safety, environmental i

matters and antitrust considerations. A license granted by the NRC may be revoked, suspended or modified for failure to construct or operate a facility l

in accordance with its terms. The Company currently holds an operating license for Pilgrim Station which expires in 2012.

Continuing NRC review of-existing regulations and certain operating occurrences at other nuclear plants have periodically resulted in the imposition of additional requirements for all nuclear plants in the United States, including Pilgrim Station.

NRC inspections and investigations can result in the issuance of notices of violation. These notices can also be accompanied by orders directing that certain actions be taken or by the imposition of monetary civil penalties.

In addition, the Company could undertake certain actions regarding Pilgrim

)

Station at the request or suggestion of its insurers or the Institute of Nuclear Power Operations,

p. voluntary association of nuclear utilities dedicated to the promotion of safety and reliability in the operation of nuclear power plants. Nuclear power continues to be a subject of political controversy and public debate manifested from time to time in the form of requests Co; various kinds of federal, state and local legislative or regulators action, direct voter initiatives or referenda or litigation.

The Company evnnot predict the extent, cost or timing of any modifications to Pilgrim Station which could be necessary in the future as a result of additional regulatory or other requirements, nor can it determine the effect I

e t such futura requirements on the continued operation of Pilgrim Station.

The Company continuously evaluates the operation of the station from the standpoint of safety, reliability and econondes.

These programs and, therefore, the estimates included in this Form 10-K are subject to revision due to changes in regulatory requirements, environmental standards, availability and cost of capital, interest rates and other assumptions.

Utility plant expenditures in 1997 were $114 million and consisted primarily of additions to the Company's transmission and distribution systems.

The Company also owns approximately 6% of W.F. Wyman Unit 4.

The 619 MW oil-fired unit located in Yarmouth, Maine, began operations in 1978 and is I

operated by Central Maine Power Company. Additional electric generation capacity is available to the Company through its contractual arrangements with other utilities and nonutilities and its participation in the New England Power Pool as further described in this item.

In December 1997, the Company entered into a purchase and sale agreement with Sithe Energies, Inc., a privately-held company headquartered in New York, to purchase its non-nuclear generating assets.

Refer to Note C to the Consolidated Financial Statements in Item 8 for more information regarding the company's fossil divestiture.

The Company's significant items of property consist of electric generating stations, substations and service centers, and are generally located on Compar y-owned land. The Company's high-tension transudssion lines are generally located on land either owned or subject to easements in its favor.

The company's low-tension distribution lines and fossil fuel pipelines are located principally on public property under permission granted by municipal and other state authorities.

As of December 31, 1997, the Company's transmission system consisted of 362 miles of overhead circuits operating at 115, 230 and 345 kilovolts (kV) and 156 ndles of underground circuits operating at 115 and 045 kV.

The substations supported by these lines are 45 transmission or combined transadasion and distribution substations with transformer capacity of 10,281 megavolt amperes (MVA), 61 4 kV distribution substations with transformer

/

capacity of 1,017 MVA and 18 primary network units with 88 MVA capacity.

In addition, high tension service was delivered to 242 customers' substations.

The overhead and underground distribution systems cover approximately 4,700 and 900 miles of streets, respectively.

HEEC, the Company's regulated subsidiary, has a distribution system that consists principally of a 4.1 mile 115 kV submarine distribution line and a substation which is located on Deer Island in Boston, Massachusetts.

HEEC provides the ongoing support required to distribute electric energy to its one customer, the Massachusetts Water Resources Authority, at this location.

The Massachusetts Energy Facilities Siting Board (EFSB) must approve Company plans for the construction of certain new generation or transmission facilities based upon findings that such facilities are consistent with state public health, environmental protection and resource use and development

- policies.

In December 1997, the Company received approval from the EFSB regarding proposed transudssion and station facilities in Hopkinton and Milford, Massachusetts.

This approval has been appealed to the Massachusetts Supreme Judicial Court.

Purchased Power Contracts

{

Information regarding long-term contracts for the purchase of electricity is included in Note M to the Consolidated Financial Statements in Item 8.

Under the Company's two long-term purchased power contracts with the Massachusetts Bay Transportation Authority (MBTA), the MBTA retains the right to utilize the combustion turbines for its own emergency use and for testing purposes while the Company retains New England Power Pool credit for their capacity and output.

7

Sales Contracts The Company has agreements with Commonwealth Electric Company and Montaup Electric Company under which each purchace 11% of the capacity and corresponding energy of Pilgrim Station and pay 11% of the unit's capital and operating costs including an annual return on investment.

The company has similar agreements with multiple municipal electric companies for a total of 3.7% of the capacity and corresponding energy of Pilgrim Station.

New England Power Pool The Company is a member of the New England Power Pool (NEPOOL), a voluntary association of electric utilities and other electricity suppliers in New England responsible for the coordination, monitoring and directing of the operations of the major generating and transmission facilities in the region.

To obtain naximum benefits of power pooling, the electric facilities of all member companies are directed by an Independent System Operator (ISO - New England) as if they were a single power system. This is accomplished through the use of a central dispatching system that uses the lowest cost generation and transmission equipment available at any given time. As a result of its participation in NEPOOL, the Company's operating revenues and costs are affected to some extent by the operations of the other members.

During 1997, the power pool was restructured with changes taking effect to the membs ship and governance provisions of the power pooling agreement along with the transferal of operating responsibility of the integrated transmission and generation system in New England to the above referenced Independent System e

operator.

Rules and procedures for bid-basa'i markets for unbundled energy se'rvices in lieu of the current cost-based pricing mechanism are under development. A spot market for installed capability is scheduled to be in effect on April 1, 1998 and the spot markets for other unbundled electric products are anticipated to be ready in the fourth quarter of 1998.

The Company's net capacity was 3,397 MW at year end 1997 and 3,444 MW at its summer peak.

Its corresponding NEPOOL capacity obligations were estimated to be 3,036 MW and 3,312 MW, respectively.

Item 7.

Management's Discussion and Analysis Electric Utility Industry Restructuring The traditionally rate-regulated electric utility industry is rapidly changing in response to the continuing market pressures for lower priced electric energy.

These pressures have resulted in regulatory and legislative proceedings at both federal and state levels designed to foster competition in the industry.

On January 28, 1998, the Massachusetts Department of Telecommunications and Energy (DTE), formerly the Department of Public Utilities (DPU), approved our restructuring sett3mnent agreement that was filed in July 1997. The DTE found that the settlement agreement substantially complied or was consistent with key provisions of a Massachusetts law enacted in November 1997 establishing a comprehensive framework for the restructuring of our industry. Major provisions of our settlement agreement include the ability for re, tail electric customers to choose their electricity supplier (referred to as retail access) as of March 1, 1998 (the retail access date).

Customers who choose not to participate in retail access will have the option of continuing to buy power from our electric delivery business at " Standard Offer" prices. Upon the retail access date, customers that continue to buy electricity under the Standard Offer will realize an average 10% savings from the rates in effect during 1997. Under the new legislation, Standard Offer customers will realize another 5% savings in electricity rates, after an adjustment for inflation, by September 1, 1999. We expect to be able to meet this additional rate reduction as a result of the divestiture of our fossil generating assets which is discussed below. Im part of our settlement aqreament, the retail delivery rates of our retained distribution business include a non-bypassable transition charge designed to recover certain costs incurred by our generation business under the traditional electric ratemaking structure which cannot be otherwise recovered in a competitive environment.

The rates of our distribution business will continue to be regulated by the DTE based on the cost of providing distribution service.

In 1997 the Emerging Issues Task Force (EITF) reached consensus on specific issues raised related to the application of Statement of Financial Accounting Standards No. 71, Accounting for the Effects of Certain Types of Regulation (S FAS 71). As part of its consensus, the EITF determined that when deregulation legislation is passed and regulatory actions have taken place providing sufficient detail for an enterprise to reasonably determine how the transition plan will affect the separable portion of its business being deregulated, the enterprise should stop applying SFAS 71 to that portion of its business. As a result of the recently passed Massachusetts electric industry restructuring legislation and the DTE order regarding our related settlement agreement, we have determined that, as of Decenber 31, 1997, the provisions of SFAS 71 no longer apply to the generation portion of our business. The EITF further determined that book values of assets and liabilities originating in the separable portion of the business no longer subject to rate-regulation should be evaluated on the basis of where the regulated cash flows to realize and settle them will be derived.

Net generating assets recoverable from the proceeds of the fossil divestiture and through the non-bypassable transition charge of our distribution business which continues to be subject to rate-regulation, therefore, remain on our consolidated balance sheet at December 31, 1997.

In addition, approximately 25% of the operations and capital costs, including a return on investment, of Pilgrim Nuclear Power Station will continue to be collected under wholesale life of the unit contracts. These contracts continue to be regulated by the Federal Energy Regulatory Commission (FERC) and are not impacted by our settlement agreement.

13

4 Divestiture of Fasoil Gen:rsting Ascats our restructuring settlement agreement includes a provision for the divestiture of our fossil generating assets no later than six months after the retail access date.

On December 10, 1997, we entered into a purchase and sale agreement with Sithe Energies, Inc., a privately-held company headquartered in New York, to purchase our non-nuclear generating assets. The proceeds from the sale of these assets will be $657 million. The net book value of these assets at December 31, 1997 is approximately $450 ndllion.

Included in the purchase price, Sithe Energies will pay $121 ndllion to us in connection with a six-month transitional power sales agreement under which we will buy power from the generating plants.

Sithe Energies will also be responsible for obligations resulting from the recently enacted utility restructuring legislation for property tax payments to communities with non-nuclear power plants. Net proceeds from the divestiture will be used to reduce the distribution transition charge.

Implementation.of the divestiture plan is subject to certain regulatory approvals including those of the DTE and the FERC, We anticipate finalization of the divestiture in mid-1998.

In Jul'y 1997, we reached an agreement with our field service union that requires the buyer of our fossil generating assets to recognize and continue to honor the provisions of the union's current collective bargaining agreement through the end of its tenm, May 2000. As part of a package offered to employees affected by the fossil divestiture, all eligible fossil and designated fossil support employees age 55 or older with at least 10 years of f service, or age 65 by July 1, 1998, were offered unreduced retirement and transition benefits under a voluntary early retirement program (VERP). Under this program, 40 people elected to retire.

Retirement dates are expected to be the first of the month following the transfer of ownership of our fossil generating assets.

Severance programs were offered to management and field service union employees affected by the fossil divestiture that did not elect or were ineligible to retire under the VERP. These severance benefits include salary payments, education / retraining allowances and outplacement services.

It is anticipated that 48 employees will receive severance benefits under these programs.

The estimated costs associated with the VERP and severance programs is approximately $21 ndllion including the effects on the retirement, life and dental plans.

Severance and employee retraining costs related to the divestiture are recoverable through the distribution transition charge under our settlement agreement. Therefore, we have established an offsetting regulatory asset for these obligations on our consolidated balance sheet at December 31, 1997.

Nuclear Asset Impairment As part of the settlement agreement, we recover our net investment in Pilgrim as of December 31, 1995 (adjusted for depreciation through 1997) through the distribution transition charge. Under the terms of the settlement agreement, we must perform a market valuation of Pilgrim by 2002. Upon acceptance of the valuation by the DTE, the resulting dollar amount, net of prudently incurred post-1995 investments in the plant, will reduce amounts collectible through the transition charge.

If the valuation is not sufficient to allow for the recovery of these investments, we will seek their recovery through the transition charge.

Due to the market pressures facing us, the ultimate recovery of these assets is not certain.

Therefore, we reduced our investment in Pilgrim by the $13 ndllion invested in the plant since January 1, 1996 as 14

an impairment loss.

An after tax charge of approximately $8 million due to this reduction was recorded to non-operating expense on our consolidated statement of income in the fourth quarter of 1997. A similar uncertainty does not exist for the ultimate recovery of the fossil generating assets as the sale proceeds agreed to in the purchase and sale agreement with Sithe Energies exceeds the net book value of these assets.

BEC Energy We are currently awaiting a decision from the DTE regarding our reorganization plan to form a holding company structure. A decision from the Securities and Exchange Commission is also pending. Approval from the Nuclear Regulatory Commission was received on February 11, 1998. This plan was approved by the FERC and our shareholders in 1997. This new structure will clearly separate our regulated and unregulated operations.

It will provide us with greater organizational flexibility allowing us to take advantage of nonutility business opportunities in a more timely manner. The holding company structure is a well established form of organization for companies conducting multiple lines of business.

In fact, all other Anvestor-owned Massachusetts electric utilities are currently organized in this manner.

Through our holding company, BEC Energy, we will seek ways to expand our customer base.

Joint Ventures We continue to conduct unregulated activities through our wholly owned subsidiary, Boston Energy Technology Group (BETG).

During 1997, BETG entered into two joint venture agreements.

BETG has a joint venture agreement with 1

RCN Telecom Services, Inc. (RCN). The final closing on this joint venture occurred in June 1997. This limited liability company (LLC) competes directly l

with local and long-distance telephone, video and Internet access companies i

for telecommunications-related services.

BETG owns 49% of the LLC while RCN l

owns 51% and maintains day-to-day nanagement responsibility.

BETG also has an energy marketing venture with Williams Energy Services Company (WESCO), a subsidiary of The Williane Companies, Inc.

This LLC, EnergyVision, markets electricity, natural gas and energy-related services to retail customers in the six New England states and began operations in February 1997.

BETG and WESCO each own 50% of EnergyVision.

Results of Operations 1997 versus 1996 j

Earnings per share of common stock were $2.71 in 1997 compared to $2.61 in 1996, a 3.8% increase as described below.

Operating revenues Operating revenues increased 6.6% over 1996 as follows:

(in thousands)

Retail electric revenues S 87,252 Demand side management revenues 1,232 Wholesale revenues (765)

Short-term sales and other revenues 22,211 Increase in operatino revenues

$109,930 Retail base revenues, consistent with the 0.8% increase in kilowatt-hour (kWh) sales in 1997, were relatively flat compared to 1996.

Increases due to warmer than normal temperatures in June and July, cooler temperatures in October and 15 t---_________

December and the stronger local economy were effset by milder than normal winter conditions during the first quarter of 1997 and lower industrial sales.

Industrial sales continue to be adversely affected by the decline in manufacturing activity in our service territory.

In addition, revenues in 1996 reflect one more day of sales due to the leap year.

Total retail electric revenues increased $87.3 million primarily due to the timing effect of fuel and purchased power cost recovery.

The increase in fuel and purchased power clause revenues reflect the current recovery of prior year undercollections. These higher revenues are offset by higher fuel and purchased power expenses and, therefore, have no net effect-on earnings.

Pilgrim performance revenues, which vary annually based on the operating l

performance of Pilgrim Station, decreased due to a lower annual capacity factor effective November 1996 reflecting the refueling and maintenance outage in the first quarter of 1997.

l Short-term sales revenues increased approximately $16 million.

This is due to the continued reduction in available nuclear energy supply in New England conbined with A 42% increase in our fossil generation allowing for increased I

l sales to the power exchange.

Revenues from short-term sales result in a corresponding reduction to future fuel and purchased power billings to retail customers and, therefore, have no net effect on earnings.

1 l

Operating expenses i

Fuel and purchased power expenses increased $90.2 ndllion.

This increase reflects $57 million related to the timing effect of fuel and purchased power l

cost recovery.

In addition, company fuel expense increased $50 million y

prAmarily due to the 42% increase in fossil generation.

These increases were partially offset by a $22 ndllion decrease in power exchange purchases.

Fuel l

l l

and purchased power expenses are substantially recoverable through fuel and purchased power revenues.

operations and maintenance expense decreased $2.6 million from 1996.

The decrease is the result of lower spending due to overall cost control efforts I

and significantly less overhaul activity at our fossil generating units.

These decreases were partially offset by an approximately $5 million l

incremental impact associated with service restoration efforts resulting from a severe snow storm in April 1997 that struck the greater Boston area.

The increase in depreciation and amortization expense is due to the net impact of two depreciation adjustments. We recorded an $8.7 million nonrecurring charge to depreciation expense in the third quarter of 1997 to reflect the l

removal of specific nuclear-related intangible assets from our balance sheet.

l In 1996 we recorded a $5.2 ndllion adjustment to correct the accumulated L

depreciation balance of certain large computer equipment.

Income taxes increased as a result of higher net income offset by a lower effective tax rate.

The effective tax rate for 1997 reflects the impact of the favorable outcome of an Internal Revenue Service (IRS) appeal received in l

the third quarter related to investment tax credits (ITC).

This also resulted l

in an increase in unamortized ITC which will be reflected as a reduction to income tax expense over the life of the related assets.

Refer to Note D to the consolidated Financial Statements for more information on income taxes.

Other expense other expense, net in 1997 reflects the charge of approximately $8 million, after tax, from the nuclear asset impairment which is further discussed in Note C to the consolidated Financial Statements in addition to BETG equity j

I 16

)

4 losses.

These decreases were partially offset by approximately $3 million, after tax, in interest income from the IRS appeal.

Interest charges Total interest charges on long-term debt decreased due to the maturing of $100 million of 5.70% debentures in March 1997 and the cessation of amortization of the associated redemption premiums. This was partially offset by the March 1997 issuance of $100 million of 6.662% bank debt due in 1999.

The decrease also reflects the naturity of $100 ndllion of 51/8% debentures in March 1996.

Allowance for borrowed funds used during construction (AFUDC), which represents the financing costs of construction, decreased primarily due to a lower average construction work in progress (CWIP) balance in 1997.

The 1996 average CWIP balance included nuclear fuel purchased in anticipation of Pilgrim Station's scheduled refueling outage in the first quarter of 1997.

Preferred stock dividends The decrease in preferred stock dividends is the result of the redemption of 20,000 of mandatory and 20,000 of optional shares of 7.27% series cumulative preferred stock in May 1997 and 400,000 shares of 8.25% series in June 1997.

Refer to Note I to the Consolidated Financial Statements.

1996 versus 1995 s

Earnings per share of common sto k were $2.61 in 1996 compared to $2.08 in 1995.

Earnings in 1995 reflect.. nonrecurring before tax charge of $34 ndllion ($20.7 ndllion af ter tax, or $0.44 per share) associated with our corporate restructuring.

The restructuring is discussed further in Note F to the Consolidated Financial Statements.

Excluding the nonrecurring

restructuring charge, earnings per common share increased 3.6% over 1995 as described below.

Operating revenues Operating revenues increased 2.3% over 1995 as follows:

Wholesale revenues (2,072)

Short-term sales and other revenues 11,768 l

l Increase in operatine revenues

$37,800 l

Retail electric revenues increased $48.6 million.

Fuel and purchased power clause revenues increased approximately $36 million.

These higher revenues are offset by higher fuel and purchased power expenses and, therefore, have no net effect on earnings.

Performance revenues increased $14.5 million as l

Pilgrim Station operated at a higher capacity in 1996.

Retail kWh sales I

increased 2.8% in 1996, primarily due to the positive economic impacts on our commercial customers.

Demand side management (DSM) revenues decreased primarily due to a decline in current DSM program expenditures.

The primary reason for the decrease in wholesale revenues is due to Pilgrim contract customer revenues. These revenues decreased despite increased kWh sales due to lower operations and maintenance expense related to Pilgrim 17

Station.

Pilgrim contract customers are billed for their proportionate share of the unit's costs.

I Net short-term sales and other revenues increased $11.8 ndllion.

Despite i

lower kWh sales, short-term sales revenues increased approximately $6 ndllion due to higher fuel prices.

Revenues from short-term sales result in a corresponding reduction to future fuel and purchased power billings to retail customers and, therefore, have no net effect on earnings.

This increase also reflects an increase in revenue from non-electric sources in 1996.

l Operating expenses l

l Fuel and purchased power expenses increased $53.1 million.

Fuel expense increased, despite a slight decrease in ecmpany generation, due to significantly higher oil and natural gas prices.

Purchased power expense reflects a higher volume of energy purchases and an overall increase in energy l

prices. These increases were partially offset by the timing effect of fuel and purchased power cost recovery.

Fuel and purchased power expenses are substantially recoverable through fuel and purchased power revenues.

Operations and maintenance expense decreased $40.8 million primarily due to lower labor costs resulting from our 1995 restructuring and the continuing cost control efforts of each of our business units.

In addition, the amortization of deferred nuclear outage costs decreased $9 ndllion. As discussed in Note B to the Consolidated Financial Statements, in the third quarter of 1995 we nmde a retroactive change to the amortization period of these deferred costs from five years to two years, consistent with the f

two-year cycle between rafueling outages at Pilgrim Station.

The 1995 operating expenses reflect a $34 ndllion nonrecurring charge related to our corporate restructuring.

Refer to Note F to the Consolidated Financial Statements for additional information regarding our 1995 restructuring.

Depreciation and amortization increased $32.2 million.

The increase is primarily the result of a change in the estimated remaining econcmic lives of our Mystic 4, 5 and 6 fossil generating units in the second quarter of 1996, retroactive to the beginning of the year, and an increase in the depreciable plant balance.

The change in estimated economic lives of Mystic 4, 5 and 6 resulted in a $22 million increase in depreciation expense for the year.

The decrease in DSM prograns expense reflects the decline in current DSM program expenditures.

The increase in income taxes is due to higher net income and a higher effective tax rate in 1996. The effective tax rate in 1996 is 38.2% versus 37.1% in 1995.

Interest charges Interest on long-term debt decreased due to the maturity of $100 nullion 8 7/8% debentures in December 1995 and $100 million 5 1/8% debentures in March i

1996.

These decreases were partially offset by the issuance of $125 million l

7.80% debentures in May 1995 which were outstanding for all of 1996.

Other interest charges increased due to an increase in interest on short-term debt caused by the higher average short-term debt level partially offset by a lower average short-term borrowing rate.

The short-term debt balance increased as a f

result of the debenture maturities and the redemption of $4 million of preferred stock in 1996. AFUDC decreased due to lower overall construction 18

i j

1 activity during 1996, shorter construction periods, and lower short-term l

interest rates.

Electric Sales and Revenues i

Electric sales Retail kWh sales increased 0.8% in 1997.

This was primarily attributable to the commercial sector. The commercial increase reflects the impact of a continued strong economy in the Boston area and very warm temperatures in June and July and cooler than nornal temperatures in the fourth quarter. Hotel occupancy rates and non-manufacturing employment continued to increase in 1997. The commercial sector represents approximately 50% of our electric operating revenues.

Residential revenues, which represent 27% of electric revenues, were also positively impacted by the weather. These positive j

impacts were offset by milder winter weather in the first quarter of 1997 and J

declines in manufacturing enployment affecting the industrial sector.

In addition, revenues in 1996 reflect one more day of sales due to the leap year.

The industrial sector represents only 9% of our electric operating revenues.

Total kWh sales increased 3.1% as a result of the continued reduction in available nuclear energy supply in New England. This reduction, combined with an increase in our fossil generation allowed for increased sales to the power exchange.

The 2.8% increase in 1996 retail kWh sales was primarily due to the positive effect on commercial customers of the strong economy in our retail service y

territory.

Residential sales decreased slightly primarily due to overall milder than normal weather conditions.

Industrial s..les remained relatively flat.

Total kWh sales, including wholesale, increased 3.3%.

The increase in wholesale sales was primarily due to higher sales to our Pilgrim contract customers as the plant was operating for substantially all of 1996.

In addition, sales to our municipal customers increased due to a reduction in available energy supply in New England.

Electric zevenues As discussed in the Electric Utility Industry Restructuring section, our delivery business will provide Standard offer customers service at rates designed to give an average 10% savings upon the retail access date.

As part of the recently passed restructuring legislation in Massachusetts, these customers are to realize an additional 5% average savings, after an adjustment for inflation, by September 1, 1999. We expect to meet this additional rate reduction as a result of the proceeds received from the divestiture of our fossil generating assets and potential securitization or refinancing of our stranded costs. Under our settlement agreement, the aggregate amount of our transition charge is reduced by the net proceeds from fossil divestiture.

Under the settlement agreement, the annual performance adjustment charge ceases and our cost recovery mechanism for Pilgrim Station changes as of the retail access date.

Approximately 25% of the operations and capital costs, including a return on investment, will continue to be collected under wholesale life of the unit contracts. The remaining output will be sold in the competitive energy market. Through December 31, 2000, we will share 25%

of any profit. or loss from the sale of Pilgrim's output with distribution customers through the transition charge.

In addition, we will obtain transition payments up to a naximum of $23 ndllion per year depending on the level of costs incurred for property taxes, insurance, regulatory fees and security requirements.

I 19

Beginning upon the retail access date, the rates of our distribution business will remain unchanged through December 31, 2000, subject to a minimum and maximum return on average common equity (ROE). We will be required to file with the DTE a computation supporting the ROE of our distribution business after each calendar year. The ROE is subject to a floor of 6% and a ceiling of 11.75%.

If the ROE is below 6%, we are authorized to add a surcharge to distribution rates in order to achieve the 6% floor.

If the ROE is above 11%,

we are required to adjust distribution rates by an amount necessary to reduce the calculated ROE between 11% and 12.5% by 50%, and a return above 12.5% by l

100%. No adjustment is made if the ROE is between 6% and 11%.

The cost of providing transmission service to distribution customers will be recovered on a fully reconciling basis.

Liquidity We ordinarily meet most of our cash requirements for plant expenditures with internally generated funds. These funds are cash flows from operating activities, adjusted to exclude changes in working capital and the payment of dividends.

During 1997, 1996 and 1995 our internal generats.n of cash j

provided 211%, 177% and 102%, respectively of our plant expenditures.

The j

capital spending level, excluding nuclear fuel, forecasted for 1998 is $265 l

ndllion which includes amounts for utility plant and the capital requirements of our nonutility ventures. This spending level also includes the 1998 portion of business system replacements discussed below.

The capital spending level over the next five years is forecasted to be approximately $940 million.

In addition to capital expenditures, we have debt and preferred stock payment l

requirements of $103.6 million in 1998 and 1999, $168.6 million in 2000, $53.6 !

million in 2001 and $3.6 million in 2002.

We supplement our internally generated funds as needed, primarily through the issuance of short-term commercial paper and bank borrowings. We have authority from the FERC to issue up to $350 million of short-term debt.

We also have a $200 million revolving credit agreement and arrangements with several banks to provide additional short-term credit on a conadtted as well as on an uncommitted and as available basis. At December 31, 1997, we had

$137 ndllion of short-term debt outstanding, none of which was incurred under the revolving credit agreement. We have $220 million remaining under our approved long-term financing plan with the DTE which is available through 1998.

Proceeds from issuances under this plan are to be used to refinance short and long-term securities and to fund capital expenditures.

Refer to Notes I and J to the consolidated Financial Statements for additional information relating to our financing activities.

At December 31, 1997, BETG had $7.5 million outstanding under a revolving credit-a g reement. The purpose of this line is to fund its capital requirements above our $45 million limited investment. This debt will be refinanced upon the formation of BEC Energy.

We anticipate using the sale proceeds from our pending fossil divestiture to adjust our capital structure.

Year 2000 computer Issue The year 2000 computer issue is the result of programs written using two digits instead of four to define an applicable year.

Consequently, these programs will not properly recognize calendar dates beginning in the year 2000. This could cause conputers to shut down or yield incorrect results.

I l

i 20 l

Wa have developed a plan to address the year 2000 issue that includes modification of certain applications and replacement of systems that are not year 2000 compliant. The cost associated with modification of existing applications will be expensed as incurred.

In addition, we have made a decision to use this opportunity to upgrade some of our less efficient centralized business systene. The full replacement costs associated with these systens will be capitalized and amortized over future periods.

The total cost of the year 2000 project is expected to be funded through internally generated funds. We anticipate completion of the year 2000 project in the third quarter of 1999.

Other Matters Environmen tal l

We are subject to numerous federal, state and local standards with respect to waste disposal, air and water quality and other environmental considerations.

These standards can require that we modify our existing facilities or incur increased operating costs.

We currently own or operate approximately 30 properties where oil or hazardous materials were previously spilled or released. We also continue to face possible liability as a potentially responsible party in the cleanup of six multi-party hazardous waste sites in Massachusetts and other states where we are alleged to have generated, transported or disposed of hazardous waste at the sites.

Refer to Note L.6. to the Consolidated Financial Statements for more information regarding hazardous waste issues.

The Accounting Standards Executive Committee of the American Institute of l

Certified Public Accountants issued Statement of Position 96-1, Environmental Remediation Liabilities (SOP 96-1), effective in 1997. This statement contains authoritative guidance on specific accounting issues related to the recognition, measurement, display and disclosure of environmental remediation liabilities.

It requires that an accrual for environmental liabilities include estimates of the costs of compensation and benefits for those employees expected to devote a significant amount t" time directly to that effort.

SOP 96-1 had no material effect on our financial position or results of operations during 1997.

Uncertainties centinue to exist with respect to the disposal of both spent I

nuclear fuel and low-level radioactive waste (LLW) resulting from the operation of Pilgrim Station. The United States Department of Energy (DOE) is responsible for the ultimate disposal of spent nuclear fuel; however, uncertainties regarding the DOE's schedule of acceptance of spent fuel for disposal continue to exist.

In 1995 we regained access to the LLW disposal facility located in barnwell, South Carolina.

Refer to Note E to the Consolidated Financial Statements for further discussion regarding nuclear decommissioning and waste disposal.

The 1990 Clean Air Act Amendments (CAAA) require a significant reduction in nationwide emissions of sulfur dioxide from fossil generating units.

Other provisions of the CAAA involve limitations on emissions of nitrogen oxides from existing generating units. Am discussed in the Divestiture of Fossil Generating Assets section, we have signed an agreement with Sithe Energies for the sale of our fossil generating assets.

If regulatory approval is not obtained or is delayed, we could continue to operate these units subject to the provisions of these amendments. We currently meet the standards of the CAAA and, depending on the outcome of certain Massachusetts Department of Environmental Protection air quality modeling studies, our generating units 21 l

i E_.___________________________

could continue to operate through at least 1999 before additional emission reductions would be required.

Public concern continues regarding electromagnetic fields ( EMF) associated with electric transudssica and distribution f acilities and appliances and wiring in buildings and homes.

Such concerns have included the possibility of adverse health effects caused by EMF as well as perceived effects on property values.

Some scientific reviews conducted to date have suggested associations between EMF and potential health effects, while other studies have not substantiated such associations.

The National Research Council previously reported that there is no conclusive evidence that exposure to EMF from power lines and appliances presents a health hazard.

The panel of scientists, working with the National Academy of Sciences, report that more than 500 studies over the last several years have produced no proof that EMF causes leukemia or other cancers or harms human health in other ways.

We continue to support r. search into the subject and are participating in the funding of industry-sponsored studies. We are aware that public concern regarding EMF in some cases has*resulted in litigation, in opposition to existing or proposed

)

facilities in proceedings before regulators or in requests for legislation or j

regulatory standards concerning EMF levels. We have addressed issues relative to EMF in various legal and regulatory proceedings and in discussions with j

customers and other concerned persons; however, to date we have not been l

significantly affected by these developments. We continue to monitor all aspects of the EMF issue.

Litigation In October 1997, the DTE opened a proceeding to investigate our compliance with the 1993 order which permitted the fonmation of BETG and authorized us to invest up to $45 million in unregulated activities. We are unable to determine the ultimate outcome of this proceeding or its impact on our operations.

We were named as a party in lawsuits by Subaru of New England, Inc. and Subaru Distributors Corporation.

The plaintiffs claimed certain automobiles stored j

on lots in South Boston suffered pitting damage caused by emissions from our l

New Boston Station generating unit.

In 1997 we settled both lawsuits.

Neither settlement had a material impact on our consolidated results of operations or financial position.

Refer to Note L.B. to the Consolidated Financial Statements for more information on other legal matters in which we are involved.

Industry restructuring legal proceedings / referendum campaign The DTE order approving our settlement agreement has been appealed by certain parties to the Massachusetts Supreme Judicial Court.

In addition, along with other Massachusetts investor-owned utilities, we have been named as a defendant in a class action suit seeking to declare certain provisions of the Massachusetts electric industry restructuring legislation unconstitutional.

We are currently unable to determine the outcome of these proceedings or their impact on us.

Opponents of the electric industry restructuring legislation that was enacted in November 1997 have mounted a referendum campaign to repeal that law.

A coalition of business, industry and public interest groups that supported the legislation, along with the electric utility industry, is opposed to the referendum and is prepared to mount an aggressive campaign to defeat it.

We 22

are currently unable to predict the eventual outcome of this referendum or its impact on us.

Safe harbor cautionary statement We occasionally nake forward-looking statements such as f oreca&ts and projections of expected future performance or statements of our plans and objectives. These forward-looking statements may be contained in filings with the Securities and Exchange Commission, press releases and oral statements.

Actual results could potentially differ materially from these statements.

Therefore, no assurances can be given that the outeemes stated in such forward-looking statements and estimates will be achieved.

The preceding sections include certain forward-looking statements about the effects of the industry restructuring process and our related settlement agreement, the divestiture of our fossil generating assete, operating results, f

year 2000 and environmental and legal issuer.

The effects of electric utility industry restructuring could differ from our expectations.

This could occur as regulatory decisions and negotiated I

settlements between utilities and interveners are finalized.

In addition, the development of a competitive electric generation market, the impacts of actual electric supply and demand in New England and further legislative action may affect the ultimate results of the industry restructuring and our settlement agreement.

I t

The divestiture plan could differ from our expectations. This could occur if required regulatory approvals are delayed or not obtained.

The impacts of our continued cost control procedures on our operating results could differ from our expectations. The effects of changes in economic conditions, tax rates, interest rates, technology and the prices and availability of operating supplies could materially affect our projected operating results.

The timing and total costs related to our year 2000 plan could differ from our expectations.

Factors that may cause such differences include the ability to i

-locate and correct all relevant computer codes and the availability of personnel trained in this area.

In addition, we cannot predict the nature or impact on operations of third party noncompliance.

The impacts of various environmental and legal issues could differ from our o

expectations. New regulations or changes to existing regulations could impose additional operating requirements or liabilities other than' expected.

The l

effects of changes in specific hazaraous waste site conditions and cleanup technology could affect our estinated cleanup liabilities. The impacts of changes in available information and circumstances regarding legal issues could affect our estimated litigation costs.

Notes to Consolidated Financial Statements Note A.

Nature of Operations Boston Edison Company (the company) is an investor-owned regulated public utility operating in the inergy, energy services and telecommunications business. This includes tne generation, purchase, t ranand s sion, distribution and sale of electric energy and the development and implementation of electric demand side management prograns. A portion of our generation is produced by our wholly owned nuclear generating unit, Pilgrim Nuclear Power Station. We supply electricity at retail to.an area of 590 square ndles, including the city of Boston and 39 surrounding cities and towns. We also supply electricity at wholesale for resale to other utilities and municipal electric departments.

Electric operating revenues were 88% retail and 12% wholesale in 1997.

We also conduct unregulated activities through our wholly owned subsidiary, Boston Energy Technology Group (BETG).

Through BETG and its subsidiaries, we are engaged in certain nonutility businesses, including energy utilization and conservation, construction management and district energy.

BETG has a joint venture with RCN Telecom Services, Inc. (RCN) that provides certain telecommunications-related services.

The limited liability company (LLC) formed from this joint venture is owned 51% by RCN and 49E by BETG, with RCN having the day-to-day management responsibility.

BETG also has a joint venture with Willians Energy Services l

Company (WESCO).

This joint venture markets electricity, natural gas and energy-related services to retail customers in the six New England states.

BETG and WESCO each own 50% of this LLC, EnergyVision.

We are current..y awaiting a decision from the Massachusetts Department of Telecommunications and Energy (DTE), formerly the Department of Public Utilities, regarding our plan to form a holding company structure. This structure will clearly separate our regulated and unregulated lines of business. Through our holding company, BEC Energy, we will seek ways to expand our customer base. After the corporate reorganization, Boston Edison will be a wholly owned subsidiary of BEC Energy.

BETG will cease being a subsidiary of Boston Edison and become a wholly owned subsidiary f BEC Energy.

The common shareholders of Boston Edison will become s5ss,

!ders of BEC Energy. The existing debt and preferred stock of Boston Edt*L 11 remain obligations of the regulated utility business.

Refer also to Note C to these Consolidated Financial Statements fc: changes in the nature of our operations as a result of the electric utility industry i

I restructuring and our related settlement agreement.

Note B.

Significant Accounting Policies 1.

Basis of Consolidation and Accountingr The consolidated financial statements include the activities of our wholly owned subsidiaries, Harbor Electric Energy Company (HEEC) and BETG. All significant intercompany transactions have been eliminated.

Certain reclassifications have been made to the prior year data to conform with the current presentation.

We follow accounting policies prescribed by the Federal Energy Regulatory Conads sion (FERC) and the DTE.

We are also subject to the accounting and reporting requirements of the Securities and Exchange Commission. The consolidated financial statements conform with generally accepted accounting principles (GAAP). As a rate-regulated company we have been subject to 27

4 Statement of Financial Accounting Standards No. 71, Accounting for the Effects of Certain Types of Regulation (SEAS 71), under GAAP.

The application of SFAS 71 results in differences in the timing of recognition of certain expenses from that of other businesses and industries. As a result of the recently passed Massachusetts electric industry restructuring legislation and the DTE order regarding our related settlement agreement, as of December 31, 1997, we are no longer applying the provisions of SFAS 71 to our generation business.

Our distribution business remains subject to rate-regulation and continues to I

meet the criteria for application of SFAS 71.

Refer to Note C to these Consolidated Financial Statements for_more information on the accounting 1

implications of the electric utility industry restructuring.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of-assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses j

during the reporting period. Actual results could differ from these i

estimates.

2.

Revenues We record estimates of retail base revenues for electricity used by our customers but not yet billed at the end of each accounting period.

3.

Forecasted Buel and Purchased Power Rates The rate charged to retail customers for fuel and purchased power allows for fuel and purchased power costs which are not included in our base rates to be billed to customers using a forecasted rate.

The difference between actual costs and the amounts billed to customers is recorded as an adjustment to fuel and purchased power expenses and is included in accounts receivable on the consolidated balance sheet until subsequent rates are adjusted.

4.

Utility Pinnt Utility plant is stated at original cost of construction.

The costs of replacements of property units are capitalized. Maintenance and repairs and replacements of ndner items are expensed as incurred. The original cost of property retired, net of salvage value, and the related costs of removal are charged to accumulated depreciation.

S.

Depreciation and Nuclear fuel Amortization l

Depreciation of our utility plant is computed on a straight-line basis using composite rates based on the estimated useful lives of the various classes of property.

Excluding the effect of the adjustment discussed below, the overall composite depreciation rates were 3.30%, 3.33% and 3.28% in 1997, 1996 and 1995, respectively.

Upon the completion of a review of our electric generating units, we determined that our oldest and least efficient fossil units (Mystic 4, 5 and

6) were unlikely to provide competitively-priced power beyond the year 2000.

Therefore we revised the estimated remaining economic lives of these units to five years in 1996.

The cost of decommissioning Pilgrim Station is excluded from our depreciation rates.

Refer to Note E to these Consolidated Financial Statements for a j

discussion of nuclear decommissioning. The cost of nuclear fuel is amortized based on the amount of energy Pilgrim Station produces. Nuclear fuel expense 28

also includes an amount for the estimated costs of ultinately disposing of spent nuclear fuel and for assessments for the decontamination and decommissioning of United States Department of Energy nuclear enrichment facilities. These costs are recovered from our customers through fuel rates.

6.

Deferred Nuclear Outnge Costs We defer the incremental costs associated with nuclear refueling outages when

{

incurred and amortize them over Pilgrim Station's operating cycle.

In 1995 we changed the amortization period from five years to two years.

The two year amortization period is consistent with the two-year cycle between nuclear refueling outages at Pilgrim Station.

7.

Costs Associated with Zusuance and Bedemption of Debt and Preferred Stock Consistent with our recovery in electric rates, we defer discounts, redemption premiums and related costs associated with the redemption and issuance of long-term debt'and preferred stock.

The costs related to long-term debt are recognized as an addition to interest expense over the life of the original or replacement debt.

Beginning in 1996, consistent with an accounting order received from the FERC, we reflect costs related to preferred stock redemptions and issuances as a direct reduction to retained earnings upon redemption or over the average life of the replacement preferred stock series as applicable.

B.

Allowance for Borrowed Funds Used During Construction (ATODC)

AFUDC represents the estimated cost-to finance utility plant construction.

In accordance with regulatory accounting, AFUDC is included as a cost of utility plant and a reduction of current interest charges. Although AFUDC is not a current source of cash income, the costs are recovered from customers over the service life of the related plant in the form of increased revenues collected as a result of higher depreciation expense.

Our AFUDC rates in 1997, 1996 and 1995 were 6.04%, 5.87% and 6.35%, respectively, and represented only the cost of short-term debt.

9.

Cash and Cash Equivalents Cash and cash equivalents are comprised of highly liquid securities with maturities of 90 days or less when purchased.

Outstanding checks are included in cash and accounts payable until they are presented for payment.

10.

Allowance for Doubtful Accounts our accounts receivable are substantially recoverable.

This recovery occurs both from customer payments and from the portion of customer charges that provides for the recovery of bad debt expense. Accordingly, we do not maintain a significant allowance for doubtful accounts balance.

11.

Regulatozy Assets Regulatory assets represent costs incurred which are expected to be collected from customers through future charges in accordance with agreements with our regulators.

These costs are expensed when the corresponding revenues are received in order to appropriately match revenues and expenses.

The majority of these costs is currently being recovered from customers over varying time periods.

Refer to Note C to these Consolidated Financial Statements for information regarding the recovery of regulatory assets related to our generation business.

Earnkags Per Shaze of Casanon Stock 4

Basic earnings per share (EPS) of common stock is calculated by dividing net income, after the payment of preferred stock dividends, by the weighted average common shares outstanding during the year.

Statement of Financial Accounting Standards No. 128, Earnings per Share, requires the disclosure of diluted EPS effective for periods ending after December 15, 1997.

Diluted EPS is similar to the computation of basic EPS except that the weighted average common shares is increased to include the number of dilutive potential common shares.

Diluted EPS, which includes the effect of deferred (nonvested) shares and stock options granted under the Stock Incentive Plan in the calculation of weighted average common shares, is the same as basic EPS displayed on the consolidated statement of income.

Note C. Electric Utility Industry Restructuring 1.

Accounting Zap].Lastions Under the traditional revenue requirements model, our electric rates have been based on the cost of providing electric service. As such, we have been subject to certain accounting standards that are not applicable to other businesses and industries in general. The application of SEAS 71 requires us to defer the recognition of certain costs when incurred if future rate recovery of these costs is expected. Based on a consensus reached by the Emerging Issues Task Force (EITF) regarding specific issues raised related to the application of SEAS 71, we have determined that, as of December 31, 1997, the provisions of SEAS 71 no. longer apply to the generation portion of our business. In its consensus, the EITF determined that when deregulation legislation is passed and regulatory actions have taken place providing sufficient detail for an enterprise to reasonably determine how the transition plan will affect the separable portion of its business being deregulated, the enterprise should stop applying SEAS 71 to that portion of its business.

On January 28, 1998, the DTE approved our restructuring settlement agreement that was filed in July 1997. The DTE found that the settlement agreement substantially complied or was consistent with key provisions of a Massachusetts law enacted in November 1997 establishing a comprehensive framework for the restructuring of our industry. The EITF further determined that book values of assets and liabilities originating in the separable portion of the business no longer subject to rate-regulation should be evaluated on the basis of where the regulated cash flows to realize and settle them will be' derived. Net utility plant and other related assets on our consolidated balance sheet as of December 31, 1997 include approximately $700 adllion related to nuclear generation and approximately $450 ndllion related to fossil generation. As part of our settlement agreement, approximately 75%

of these nuclear assets are fully recoverable through the non-bypassable 30

. transition charge of our distribution business which continues to be subject to rate-regulation. The remaining 25% will be collected under Pilgrim's wholesale life of the unit contracts. These contracts continue to be l

regulated by the FERC and are not impacted by our settlement agreement.

These fossil assets will be recovered from the proceeds from their sale as discussed in part 2 below.

i The implementation of our approved settlement agreement has certain accounting implications. The highlights of these include:

Deprecia tion The composite depreciation rate for distribution utility plant increases from 2.38% to 2.98% as of March 1, 1998 (the retail access date).

Generation related plant and requistoxy assets Plant and regulatory assets related to our generation business, except for those related to Pilgrim's wholesale life of the unit contracts, will be recovered through the transition charge. This recovery, which includes a return, will occur over a twelve-year period.

Storm fund Under the settlement agreement, we are authorized to establish a storm contingency fund to use for the incremental costs of any major storm (in excess of $1 million). The settlement required that we initially establish the fund with $8 udllion of proceeds received from the a le of Clean Air Act emission allowances. As costs are charged against the fund, the balance will be restored to the original level from distribution charges up to a maximum of

$3 ndllion per year.

Tuel and purchased power charge The fuel and purchased power charge ceases as of the retail access date.

Net remaining over or under collection of fuel and purchased power costs will be retlected in future customer billings.

Standard offer chntge Customers will have the option of continuing to buy power from our electric j

delivery business at " Standard Offer" prices as of the retail access dats.

The Standard offes charge begins at 2.8 cents at retail access and increases l

to 5.1 cents by 2004.

The cost of providing Standard Offer service, which includes fuel and purchased power costs, will be recovered from Standard Offer customers on a fully reconciling basis.

1 Distribution and tz=n==4ssion shazgos Distribution rates will be subject to a ndnimum and naximum return on average common equity (ROE) through December 31, 2000. The ROE is subject to a floor of 6% and a ceiling of 11.75%.

If the ROE is below 6%, we are authorized to add a surcharge to distribution rates in order to achieve the 6% floor.

If the ROE is above 11%, we are required to adjust distribution rates by an amount necessary to reduce the calculated ROE between 11% and 12.5% by 50%,

and a return above 12.5% by 100%. No adjustment is made if the ROE is between 6% and 11%.

In addition, distribution rates will be adjusted for any changes in tax laws or accounting principles that result in a change in our costs of 31

more than $1 ndllion.

The cost of providing transmission service to distribution customers will be recovered on a fully reconciling basis.

Nuclear generation Under the settlement agreement, the annual performance adjustment charge ceases and our cost recovery mechanism for Pilgrim Station changes as of the retail access date.

Approximately 25% of the operations and capital costs, including a return on investment, will continue to be collected under wholesale life of the unit contracts.

The remaining output will be sold in the competitive energy market. Through December 31, 2000, we will share 25%

of any profit or loss from the sale of Pilgrim's output with distribution customers through the transition charge.

In addition, we will obtain

. transition payments up to a maximum of $23 million per year depending on the level of costs incurred for property taxes, insurance, regulatory fees and security require.ments.

Nuclear deconan'issioningr Approximately 25% of Pilgrim's decommissioning costs will continue to be collected under wholesale life of the unit contracts. The remaining portion will be recovered through the transition charge. Amounts collected for decommissioning will be adjusted as decommissioning cost studies are updated.

Refer to Note E to these consolidated Financial Statements for more information on nuclear decommissioning costs.

i 2.

Divestiture of Tossil Generating' Assets Included in our settlement agreement is a provision for the divestiture of our fossil generating assets.

On December 10, 1997, we entered into a purchase and sale agreement with Sithe Energies, Inc., a privately-held company headquartered in New York, to purchase our non-nuclear generating assets. The proceeds from the sale of these assets will be $657 million.

The net book value of these assets at December 31, 1997 is approximately $450 ndllion.

Included in the purchase price, Sithe Energies will pay $121 million to us in connection with a six-month transitional power sales agreement under which we will continue to buy power from the generating plants.

Sithe Energies will also be responsible for obligations resulting from the recently enacted utility restructuring legislation for property tax payments to communities with non-nuclear power plants.

In July 1997, we reached an agreement with our field service union that requires the buyer of our fossil generating assets to recognize and continue to honor the provisions of the union's current collective bargaining agreement through the end of its term, May 2000. As part of a package offered to employees affected by the fossil divestiture, all eligible fossil and designated fossil support employees age 55 or older with at least 10 years of service, or age 65 by July 1, 1998, were offered unreduced retirement and transition benefits under a voluntary early retirement program (VERP).

Under this program, 40 people elected to retire.

Retirement dates are expected to be the first of the month following the transfer of ownership of our fossil generating assets.

Severance programs were offered to management and field service union employees affected by the fossil divestiture that did not elect or were ineligible to retire under the VERP.

These severance benefits include salary payments, education / retraining allowances and outplacement services.

It is anticipated that 48 employees will receive severance benefits under these programs.

1 32

)

The estimated costs associated with the VERP and severance programs is approximately $21 ndllion including the ef fects on the retirement, life and dental plans.

Severance and employee retraining costs related to the divestiture are recoverable through the distribution transition charge under our settlement agreement.

Therefore, we have established an offsetting regulatory asset for these obligations on our consolidated balance sheet at December 31, 1997.

3.

Nuclear Asset Zapsizment As part of the settlement agreement, we recover our net investment in Pilgrim Station as of December 31, 1995 (adjusted for depreciation through 1997; through the distribution transition charge. Under the terms of the settlement agreement, we must perform a market valuation of Pilgrim by 2002. Upon acceptance of the valuation by the DTE, the resulting dollar amount, net of prudently incurred post-1995 investments in the plant, will reduce amounts collectible through the transition charge.

If the valuation is not sufficient to allow for the recovery of these investments, we will seek their recovery through the transition charge.

Due to the market pressures facing us, the ultimate recovery of these assets is not certain. Therefore, we reduced our investment in Pilgrim by the $13 million invested in the plant since Jcnuary 1, 1996 as an impairment loss under Statement of Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of (SEAS 121). An after tax charge of approximately $8 million due to this reduction was recorded to non-operating expense on our consolidated statement of income in the fourth quarter of 1997.

A similar uncertainty does not exist for the ultimate recovery of the fossil generating assets as the sale proceeds agreed to in the purchase and sale agreement with Sithe Energies exceeds the net book value of these assets.

Note D.

Income Tas,s 4

Income taxes are accounted for in accordance with Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes (S EAS 109 ).

SEAS 109 requires the recognition of deferred tax assets and liabilities for the future tax effects of temporary differences between the carrying amounts and the tax basis of assets and liabilities.

In accordance with SEAS 109 we recorded net regulatory assets of $51.1 million and $47.5 million and corresponding net increases in accumulated deferred income taxes as of December 31, 1997, and December 31, 1996, respectively. The regulatory assets represent the additional future revenues to be collected from customers for deferred income taxes.

Note E. Nuclear Decommissioning and Nuclear Waste Disposal 2.

Nuclear Decommissioning When Pilgrim Station's operating license expires in 2012 we will be required to decommission the plant.

Decommissioning means to remove nuclear facilities from service safely and reduce residual radioactivity to a level that permits termination of the Nuclear Regulatory Commission (NRC) license and release of the property for unrestricted use.

We record an estimate of decommissioning costs in depreciation expense on the consolidated statements of income over Pilgrim's expected service life.

Decommissioning expense is approximately $14 million~per year. The estimate used to determine our annual expense is basai on a 1991 study that documents a cost of approximately $328 million to decommission the plant using the " green field" method, which provides for the plant site to be completely restored to its original state.

The cost estimate was incorporated in our 1992 retail settlement agreement. We receive recovery of the annual expense through charges to our retail customers and from other utility companies and municipalities which purchase a contracted amount of Pilgrim's electric generation. The funds we collect from deconadssioning charges are deposited in an external trust and are restricted to use for decomndssioning and related expenses. The net earnings on the trust funds, which are also restricted, increase the nuclear decommissioning trust balance, thus reducing the amount to be collected from customers.

The 1991 decommissioning study was partially updated for internal planning purposes in order to evaluate the potential impact of Irng-term spent fuel storage options resulting from delays in the United States Department of 34

b 4

Energy (DOE) spent fuel removal program.

Refer to part 2 for a discussion of spent fuel removal. The partial update indicated an estinated decommissioning cost of $400 millien in 1991 dollars based upon a revised spent fuel removal schedule and utilization of dry spent fuel storage technology.

We are in the process of updating this study. No final cost estimate is currently available; however, we continue to monitor DOE spent fuel removal schedules

]

and developments in spent fuel storage technology along with their impact on the decommissioning estimate.

Certain financial reporting considerations related to nuclear decommissioning costs have not been fully resolved.

In 1996 the Financial Accounting Standards Board (EASB) issued proposed new rules for accounting for liabilities related to closure and removal of long-lived assets, which include decommissioning of nuclear generating facilities.

If these proposed rules are adopted we would be required to retroactively recognize the entire estimated liability for decommissioning costs on the balance sheet, offset by an addition to utility plant. The plant addition would be depreciated over Pilgrim's remaining expected service life. The liability would be measured based on the present value of estimated future cash flows. The cumulative effect of adoption of these prcposed rules could result in the recognition of a regulatory asset to be recovered from Oustomers to the extent that the present value difference in the liabildcy between when the liability was incurred and when the rules are adoptod exceeds the depreciation expense previously recognized for decommissioning.

In addition, trust fund earnings would be reported on the income sta'ement.

The EASB recently resumed its deliberations on this project. No date has been set for the issuance of either a final statement or revised proposed rules.

Spent Nuclear Duel l

The spent fuel storage facility at Pilgrim Station is expected to provide storage capacity through approximately 2003. We have a license amendment from the NRC to modify the facility to provide sufficient room for spent nuclear fuel generated through the end of Pilgrim's operating license in 2012; however, any fur ther modifications are subject to review by the DTE.

We are actively exploring the feasibility of other spent fuel storage facilities and technologies.

Delays in identifying a permanent storage site have continually postponed plans for the DOE's long-term storage and disposal site for spent nuclear fuel.

The DOE's current estimate for an available site is 2010.

In November 1997, the U.S.

Court of Appeals for the District of Columbia Circuit ruled that the lack of an interim storage facility does not excuse the DOE from j

meeting its contract obligation to begin accepting spent nuclear fuel no later than January 31, 1998. This decision was in response to petitions filed by us and other interested parties seeking declaratory rulings concerning enforcement and remedies for the DOE's f ailure to accept spent fuel in a timely manner. The court directed the plaintiffs to pursue relief under terms of their contracts with the DOE.

Based on this ruling, the DOE may ha ve to pay contract damages if it does not take the spent nuclear fuel as scheduled.

l l

Under the Nuclear Waste Policy Act of 1982, it is the ultimate responsibility of the DOE to permanently dispose of spent nuclear fuel.

We currently pay a i

fee of $1.00 per net megawatthour sold from Pilgrim Station generation under a nuclear fuel disposal contract with the DOE.

The fee is collected from customers through fuel charges. We cannot predict at this time whether or on what schedule the DOE will eventually construct a spent fuel repository or what the effect will be of any delays in such construction.

35

4 The DOE recently denied our petition to auspend payments made to the Nuclear Waste Fund based on its interpretation of the U.S. Court of Appeal's decision made in November 1997. The DOE has, however, made an offer to consider amendments to existing contracts to address the hardships the anticipated delay in accepting spent fuel may cause individual contract holders. We continue to monitor this situation and consult with legal counsel as to our next course of action.

3.

Low-Level Radioactive Waste We regained access to low-level radioactive waste (LLW) disposal facilities located in Barnwell, South Carolina, in 1995. This site is currently the only disposal facility available to us.

Legislation has been enacted in Massachusetts establishing a regulatory process for managing LLW, including the possible siting, licensing and construction of a disposal facility within the state, or, alternatively, an agreement with one or more other states.

Pending the construction of a disposal facility within the state or the adoption by th'e state of some other LLW management procedure, we will continue to monitor the situation and investigate other available options.

Note F.

1995 Corporate Restructuring In 1995 we streamlined the corporate organization and reorganized the company into separate business units in order to strengthen our competitiveness in the changing electric energy market. In conjunction with this reorganization we offered enhanced retirement programs and implemented a special severance program to reduce employee staffing levels. Under the enhanced retirement programs 330 employees elected to retire, and 149 employeea whose rosi* ions were eliminated became eligible for benefita under the speciar severance program. These programs resulted in a $34 ndllion pre-tax chat:9 ($20.7 million after tax) over the third and fourth quarters of 1995. The charge consisted of $24 million for the retirement programs and $10 ndllion for the severance program.

Note G.' Pensions and other Postratirement Benefits 2.

Pensions We have a defined benefit funded retirement plan with certain contributory features that covers substantially all employees.

Benefits are based upon an employee's years of service and highest eligible average compensation during the last ten years of credited employment. Our funding policy is to contribute an amount each year that is not less than the minimum required contribution under federal law or greater than the maximum tax deductible amount. The retirement plan assets consist of equities, bonds, money market funds, insurance contrhets and real estate funds.

We also have an unfunded supplemental retirement plan for certain management employees.

Benefits under this plan are based upon an employee's years of service and highest eligible average compensation during years of credited employment.

! Jet pension cost recognized in 1995 was $28 million.

We experienced a high number of employee retirements from 1994 to 1996. A large number of these retirements were as a direct result of our 1995 corporate restructuring.

In 1997, a review of the accounting for the pension expense related to the retirements revealed that an adjustment to the pension costs related to these employees was necessary.

Therefore, we increased our pension regulatory asset by $8.6 million in 1997 for the adjustment related to the period of our 1992 settlement agreement. The remaining adjustment did not have a material impact on our consolidated results of operations or financial pcsition.

We used the following assumptions for calculating pension cost:

2.

Other Postretirement Benefits In addition to pension benefits, we also provide health care and other benefits to our retired employees who meet certain age and years of service eligibility requirements. These postretirement benefits other than pensions (PBOPs) are accounted for in accordance with Statement of Financial Accounting 38

Standards No. 106, Employers' Accounting for Postretirement Benefits Other Than' Pensions (SEAS 106).

Our 1992 retail rate settlement agreement provided L

us with a phase-in to full expense of the PBOP costs incurred under SEAS 106.

This~ settlement agreement allowed us to defer any costs in excess of the specified phase-in amounts to the extent that we funded an external trust.

Our funding policy is to generally contribute 100% of PBOP costs to external trusts. Therefore, we recognized $23 adllion of PBOP costs in 1995 in accordance with the 1992 settlement agreement.

Beginning in 1996 we recognized the full PBOP costs incurred under SEAS 106.

The net deferred PBOP costs of S15 million resulting from the delayed phase-in are included in regulatory assets as these costs will be recovered from customers in future periods.

Stock-Based Compensation i

In 1997, we initiated a Stock Incentive Plan (the Plan) which was adopted by the Board of Directors and approved by our stockholders.

The Plan permits a variety of stock and stock-based awards, including stock options and deferred (nonvested) stock to be granted to certain key employees.

The Plan limits the terns of awards to ten years. Subject to adjustment for stock-splits and similar events, the aggregate number of shares of common stock that may be delivered under the Plan is 2,000,000, including shares issued in lieu of or upon reinvestment of dividends arising from awards.

During 1997, we granted 73,820 shares of deferred. stock and 298,400 ten-year non-qualified stock options under the Plan. The weighted average grant date fair value of the deferred stock is $27.26.

The optiore were granted at the full market price of the stock on the date of the grant.

Both awards vest ratably over a three-year period.

We recognize compensation cost for our stock-based awards under the provisions of APB Opinion 25, which requires compensation cost to be measured by the quoted stock market price at the measurement date less the amount, if any, an employee is required to pay. The required fair value method disclosures related to our stock-based compensation are as follows:

Longr-tem Debt The 9 7/8% debentures due 2020 are first redeemable in June 2000 at a redemption price of. 104.483%, the 9 3/8% series due 2021 are first redeemable in August 2001 at 104.612%, the 8.25% series due 2022 are first redeemable in-Septenber 2002 at 103.780% and the 7.80% series due 2023 are first redeemable in March 2003 at 103.730%. No other series are redeemable prior to maturity.

There is no sinking fund requirement for any series of our debentures.

Sewage facility revenue bonds were issued by HEEC.

The bonds are tax-exempt, subject to annual mandatory sinking fund redemption requirements and mature through 2015.

In both May 1996 and 1997, we redeemed $1.6 million as scheduled.

The weighted average interest rate of the bonds is 7.3%.

A portion of the proceeds from the bonds is in reserve with the trustee.

If HEEC should have insufficient funds to pay for extraordinary expenses, we would be required to make additional capital contributions or loans to the subsidiary up to a maximum of $1 ndllion.

The 5.75% tax-exempt unsecured bonds due 2014 are redeemable beginning in February 2004 at a redemption price of 102%.

The redemption price decreases to 101% in February 2005 and to par in February 2006.

In March 1997, we obtained $100 million of 6.662% notes in the form of a bank loan. This note matures in 1999.

The aggregate principal amounts of our long-term debt (including HEEC sinking fund requirements) due through 2002 are $101.6 million in 1998 and 1999,

$166.6 million in 2000 and $1.6 million in 2001 and 2002.

2.

Short-tem Debt We have. arrangements with certain banks to provide short-term credit on both a committed and an uncommitted and as available basis.

We currently have

. regulatory authority to issue up to $350 million of short-term debt.

We have a $200 million revolving credit agreement with a group of banks. This agreement is intended to provide a standby source of short-term borrowings.

Under the terms of this agreement we are required to maintain a common equity ratio of not less than 30% at all times.

Commitment fees must be paid on the unused portion of the total agreement amount.

Information regarding our utility short-term borrewings, comprised of bank leans and commercial paper, is as follows:

Note K. Fair Value of Financial Instruments The following methods and assumptions were used to estimate the fair value of each class of securities for which it is practicable to estinate the value:

Nuclear decommissioning trust:

The cost of $151.6 million approximates f air value based on quoted narket prices of securities held.

Cash and cash equivalents:

The carrying amount of $4.1 million approximates fair value due to the short-tarm nature of these securities.

Mandatory redeemable cumulative preferred stock, sewage facility revenue bonds and unsecured debt:

The fair values of these securities are based upon the quoted market prices of similar issues.

Carrying amounts and fair values as of December 31, 1997, are as follows:

Contractual Comunitments At December 31, 1997, we had estimated contractual obligations for plant and equipment of approximately $18 million.

We have leases for certain_ facilities and equipment.

Our estimated minimum rental commitments under both transmission agreements and noncancellable leases for the years after 1997 are as follows:

Amounts above include $2.7 million which is expected to be assumed by Sithe Energies as part of our pending fossil divestiture discussed in Note C to these Consolidated Financial Statements.

The total of future minimum rental income to be received under noncancellable subleases.related to the above leases is $300,921.

We will capitalize a portion of these lease rentals as part of plant I-expenditures in tne. future. The total expense for both lease rentals and transmission agreements was $27.5 million in 1997, $26.3 million in 1996 and 1

l' 45

$24.5 million in 1995, net of capitalized expenses of $1.2 million in 1997,

$2.9 ndllion in 1996 and $2.7 ndllion in 1995.

We previously entered into various take or pay and throughput agreements, primarily to supply our New Boston fossil generating station with natural gas.

The fixed and determinable portions of the obligations associated with these agreements are $19.5 million in 1998 and 1999 and $14.6 million in 2000. As part of our fossil divestiture agreement, Sithe Energies has agreed to assume these obligations. The total expense under these agreements was $47.1 million

{

in 1997, $49.5 million in 1996 and $13.9 million in 1995.

Electric Conpany Investments We have an approximately 11% equity investment in two companies which own and operate transmission f acilities to import electricity f rom the Hydro-Quebec system in Canada. As an equity participant we are required to guarantee, in addition to our own share, the total obligations of those participants who do not meet certain credit criteria. At December 31, 1997, our portion of these guarantees was $16.6 million.

We have a 9.5% equity investment of approximately $2 million in Yankee Atomic Electric Company (Yankee Atomic).

In 1992 the board of directors of Yankee Atomic decided to discontinue operations of the Yankee Atomic nuclear generating station permanently and deconadssion the f acility.

Yankee Atomic received approval from the FERC to continue to collect its investment and decommissioning costs through 2000, the period of the plant's operating license. The estimate of our share of Yankee Atomic's investment and costs of deconadssioning is approximately $13 million as of December 31, 1997.

This estimate is recorded on our consolidated balance sheet as a power contract liability and an offsetting regulatory asset.

We also have a 9.5% equity investment in Connecticut Yankee Atomic Power Company (CYAPC) of approximately $11 million.

In December 1996, the board of directors of CYAPC, which owns and cperates the Connecticut Yankee nuclear electric generating unit (Connecticut Yankee), unanimously voted to retire the unit.

The decision was based on an economic analysis of the costs of operating the unit through 2007, the period of its operating license, compared to the costs of closing the unit and incurring replacement power costs for the same period.

The current estimate of the sum of future payments for the closing, decommissioning and recovery of the remaining investment in Connecticut Yankee is approximately $615 million.

Our share of these remaining estimated costs is $58 million.

This estimate is recorded on our consolidated balance sheet as a power contract liability and an offsetting regulatory asset similar to Yankee Atomic.

In early 1997, CYAPC filed a rate case at the FERC seeking to recover certain post-operating costs, including decommissioning. The Connecticut Department of Public Utility Control (DPUC) has raised concerns to the FERC regarding CYAPC's estimate of these costs and the plant operator's prudency prior to the shutdown decision. The FERC set CYAPC's request for hearing before an Administrative Law Judge. The DPUC subsequently filed testimony in the proceeding asserting the position that the FERC should deny recovery of substantial post-operating costs, including a significant amount related to decommissioning and the return on CYAPC's undepreciated investment. We are currently unable to determine the ultimate outcome of this proceeding or its impact.

Nuclear Insurance The federal Price-Anderson Act currently provides $8.9 billion of financial protection for public liability clains and legal costs arising from a single nuclear-related accident.

The first $200 million of nuclear liability is covered by commercial insurance. Additional nuclear liability insurance up to

$8.7 billion is provided by a retrospective assessment of up to $79.3 million per incident levied on each of the 110 nuclear generating units currently licensed to operate in the United States, with a maximum assessment of $10 million per' reactor per accident in any year.

- We have purchased insurance from Nuclear Electric Insurance Limited (NEIL) to cover some of the costs to purchase replacement power during a prolonged accidental outage and the cost of repair, replacement, decontamination or decenudssioning of our utility property resulting from covered incidents at Pilgrim Station.

Our maximum potential total assessment for losses which occur during current policy years is $10.4 ndllion under both the replacement power and excess property damage, decontamination and decommissioning policies.

4.

Hazardous Wasta We are an owner or operator of approximately 30 properties where oil or hazardous materials were spilled or released. As such, we are required to clean up these properties in accordance with a timetable developed by the Massachusetts Department of Environmental Protection. We continue to evaluate the costs associated with site cleanup. There are uncertainties associated with these costs due to the complexities of cleanup technology, regulatory requirements and the particular characteristics of the different sites. We also continue to face possible liability as a potentially responsible party in the cleanup of six multi-party hazardous waste sites in Massachusetts and other states where we are alleged to have generated, transported or disposed of hazardous waste at the. sites. We are one of many potentially responsible parties and currently expect to have only a small percentage of the potential liability. Through December 31, 1997, we have accrued approximately $7 million related to our cleanup liabilities. We are unable to fully determine a range of reasonably possible cleanup costs in excess of the accrued amount, although based on our assessments of the specific site circumstances, we do l

not believe that it is probable that any such additional costs will have a material impact on our financial condition.

However, it is reasonably possible that additional provisions for cleanup costs that nay result from a change in estimates could have a material impact on the results of a reporting period in the near term.

5.

Generating Unit Perfo2xnance Program our recovery of the incremental purchased power costs resulting from outages at our generating units occurring through the retail access date is subject to review by the DTE.

We are unable to fully determine a range of reasonably possible disallowance costs in excess of amounts accrued, although, based on the information currently available, we do not believe that it is probable that any such additional costs will have a material impact on our financial condition.

However, it is reasonably possible that additional disallowance costs that may result from a change in estimates could have a material impact on the results of a reporting period in the near term.

Litigation In October 1997, the DTE opened a proceeding to investigate our compliance with the 1993 order which permitted the formation of BETG and authorized us to invest up to $45 ndllion in unregulated activities.

We are unable to determine the ultimate outcome of this proceeding or its impact on our operations.

In the normal course of our business we are involved in certain other legal matters.

We are unable to fully determine a range of reasonably possible litigation costs in excess of amounts accrued, although, based on the information currently available, we do not believe that it is probable that any such additional costs will have a material impact on our financial condition.

However, it is reasonably possible that additional litigation costs that may result from a change in estimates could have a material impact on the results of a reporting period in the near term.

1.

Industzy Restructuring Legal Proceedings / Referendum Campaign The DTE order approving our settlement agreement has been appealed by certain parties to the Massachusetts Supreme Judicial Court.

In addition, along with other Massachusetts investor-owned utilities, we have been named as a defendant in a class action suit seeking to declare certain provisions of the Massachusetts electric industry restructuring legislation unconstitutional.

We are currently unable to determine the outcome of these proceedings er their impact on us.

Opponents of the electric industry restructuring leg.slation that was enacted d

in November 1997 have mounted a referendum campaign to repeal that law.

A coalition of business, industry and public interest groups that supported the legislation, along with the electric utility industry, is opposed to the referendum and is prepared to mount an aggressive campaign to defeat it.

We are currently unable to predict the eventual outcome of this referendum or its impact on us.
