he year 1990 was an outstanding one for Detroit Edison. Record revenues, near record sales, record earnings for common stock, a 23 percent increase in earnings per share, common stock reaching a 23-year high of $30.25 and closing at $28.25 - up I1 percent from the 1989 close - and a market price-to-book value ratio rising to a level among the highest in the industry. Clearly we are proud of these results and of the people who worked extremely hard to achieve them. Following are some of their accomplishments: Compared with 1989, they produced more with less - 5 Setting a kilowatthour sales mark second only to the record hot year of 1988, despite a significant downturn late in the year as the national recession took hold. Of particular note is that while sales to the automotive and steel industries dropped significantly, sales to the commercial segment increased, setting records in nine of the 12 months and all four quarters, as well as for the year as a whole. 5 Reducing fuel and other power supply costs. E Keeping the growth of other operation and maintenance expenses well below the general level of inflation. E improving the efficiency of our fossil fuel power plants, placing us for the second consecutive year in the top 10 among the 100 largest U.S. utilities. E Setting new operating records for our Fermi 2 nuclear power plant, with capacity. factor and availability surpassing industry averages for the first time. E Making effective use of company assets by selling electricity outside our service area when capacity was available and transmitting, for a fee, electricity produced by neighboring utilities and sold to Canada. E Producing and delivering more electricity to more customers with 14 percent latter to Shareholders i ewer employes than we had three years ago. On the financial side: Power Supply 4 E We reduced costs by refinancing older, higher-cost debt with lower-cost debt. Nucle:r Generation 6 E We increased our common stock dividend to an indicate'd annual rate of $1.78 Energy hlarketing 8 per share from $1.68 per share in 1990 and again - to an indicated annual rate ynd Distribution of $1.88 -in February 1991. N'u$lt["[upport E We issued mortgage bonds for $537.1 millimi to purchase the remaining ii rin:ncial neview 12 percent share of our Fermi 2 nuclear plant held by the Wolverine Power Supply Cooperative, Inc., and still maintained the common equity portion of our capital-Fin:ncist Statements 14 structure at 32.8 percent.1With no major construction under way we anticipate

a a J hard at those changes - to learn more about our business environment and our custom- - ers, to give greater focus to our goals, to transform our commitment to continuous improvement from words to across the-board action, and to change that elusive concept-called corporate culture - expecting more of employes'and giving them, in turn, the - ' opportunity to share in the increased value resulting from their increased contributions. These changes represent a long-term process, made necessary because the competitive pressures that have challenged major segments of American industry in an increasingly global economy are now extending to the electric utility industry as well. The protec- . tion once afforded by regulation is being eroded by the demands of industry, on the one hand, and increasing regulatory reliance on market forces on the other hand. For Detroit Edison,' the need to change has been particularly critical. Construction of - new state-of-the-art power plants, the need to import all of our fuel from other states, and Michigan's high business costs and stringent endreamental replation all raised - our costs. Our goal had to be to overcome these and other factors to enable us to provide superior value to our customers - competitive prices and better service - in order to provide '; increased shareholder value. For several years now we have been involved in a series of initiatives to help us change - into the kind of company we believe we must become, We are pleased with the signifi-cant progress made to date - thanks largely to efforts by employes to change systems, work methods, policies and practices after generations of what had become standard and comfortable ways of doing things. We have swallowed our traditional pride - and have beco'me better listeners - with a massive effort to find out how the "best-in-class" among utilities and other industrial and service companies do things, then adapting the most successful practices to our own operations. As part of our effort to change the culture of our company we are empowering em-ployes further down the line to make more decisions and accept greater accountability. A new compensation plan, which rewards employes for the achievement of important shareholder value goals, establishes a framework for this change. One other major obstacle that lay in the way of our efforts to become a lower-cost-company was the threat of new clean air legislation that would require massive new-expendimres. Michigan utilities - and their customers - already had spent far more on environmental protection than utilities in most other states - and achieved far greater results. Fairness demanded that we and they not pay the price again, We delivered that message in Washington; the Michigan congressional' delegation understood it and agreed with it, and worked hard to include in the new act provisions that would ensure equity.

Aa a result, Detroit Edison already is in compliance with the first phase of the new requirements, which take effect in 1995, and therefore will not require ne_w expendi-tures by that date. Moreover, we estimate capital ex~penditures of about'$170 million to comply with phase two, which begins in 2000, while utilities in other states wi_Il be spending hundreds of millions and even billions of dollars to comply with both phases.

Our improved financial results during the last two years have been dramatic. Still, it ,

The regulatory process limits the recovery of capital investment to material effect on net income. the historical cost of the Company's investment in utility plant. This produces cash Dows which are inadequate to replace such property in future years, but the Company believes that it will be allowed to recover the increased cost of replacement facilities when, and if, replacement occurs. The cost of fuel used in the generation of electricity, the Company's single largest expense,is subject to increase due to price escalation provisions in long term coal contracts. The MPSC's December 1988 order suspends, for the four year period January 1,1989 through December 31,1992, the PSCR Clause which provided for the current recovery of fuel and purchased and net interchange power expense, llowever, it is expected that such expenses will be relatively stable during the four-year period. 2 Pursuant to the MPSC's December 1988 order <a new expense stabilization procedure applicable to approximately $750 million of Company operation and maintenance expenses, permits rates to 6 adjusted for the effects of inflation.

Accounting Issues in December 1987, the Financial Accounting Standards Board ("FASB") issued SFAS No. 96," Accounting for income Taxes," however, the effective date was deferred to 1992. SFAS No. 96 requires an asset and liability approach for financial accounting , and reporting for income taxes. It requires the Company to recompute its tax liability at the then current tax rate and adjust the Accumulated Deferred Income Tax asset and liability amounts in the Consolidated Balance Sheet. In addition,it requires the Company to record additional deferred income taxes for temporary differences not previously recognized and all other existing differences that will result in taxable or deductible amounts in future years. SFAS No. 96 requires the recognition of an asset to the extent that such additional deferred incor.te taxes are associated i 19%Qt%lOxnkMiPegwt hh
