Forward-Looking Statements

Certain information presented herein includes forward-looking statements. Forward-looking statements involve certain risks and uncertainties that may cause actual future results to differ materially from those contemplated, projected, estimated or budgeted in such forward-looking statements. Factors that may impact forward-looking statements include, but are not limited to, interest rates, the use of derivative instruments and their related accounting treatment, access to the capital markets and capital market conditions, the level of borrowings, the effects of weather and other natural phenomena on operations, actual sales, the capital intensive nature of our business, economic climate and growth in the geographic areas in which the Company does business, the timing and extent of changes in commodity prices for electricity and gas, unscheduled generation outages, maintenance or repairs, conditions of capital markets including the effect on our pension plan investments, nuclear power plant performance, the nature, availability and projected profitability of potential projects and other investments available to us, changes in the cost of fuel and purchased power due to the suspension of the power supply cost recovery mechanism, the effects of increased competition from other energy suppliers and the implementation of electric and gas Customer Choice programs, as well as alternative forms of energy, the implementation of electric utility restructuring in Michigan (which involves pending regulatory and related judicial proceedings and actual and possible reductions in authorized rates and earnings), the effects of changes in governmental policies including income taxes, environmental compliance and nuclear requirements and the ability to recover these costs through rate increases, the impact of FERC and MPSC proceedings and existing and proposed regulations, the contributions to earnings by our non-regulated businesses, changes in the cost of natural gas, the effects of new accounting pronouncements and the timing of the accretive effects of DTE Energy’s merger with MCN Energy.

RESULTS OF OPERATIONS

DTE Energy reported earnings of $161 million or $.96 per diluted share for the 2002 third quarter, compared to earnings of $63 million or $.38 per diluted share for the 2001 third quarter. For the 2002 nine-month period, net income was $429 million or $2.62 per diluted share, compared to $114 million or $.76 per diluted share for the same period in 2001. The comparability of earnings was affected by merger and restructuring charges and goodwill amortization associated with the MCN Energy merger that reduced after-tax earnings for the 2001 third quarter by $21 million or $.13 per diluted share and the 2001 nine-month period by $190 million or $1.26 per diluted share. Excluding merger and restructuring charges and goodwill amortization, earnings increased $77 million and $125 million in the 2002 third quarter and nine-month period, respectively, compared to the corresponding 2001 periods. The significant improvements reflect increased contributions from both the regulated and non-regulated businesses and a favorable adjustment in the effective income tax rate. The issuance of 29 million shares of DTE Energy common stock in conjunction with the May 2001 MCN Energy merger, net of 10.5 million shares repurchased in 2001, and the issuance of 6.325 million shares in June 2002 also impacted the earnings per share comparison.

New reporting alignment — Beginning in 2002, DTE Energy realigned its internal and external financial reporting structure into three strategic business units (Energy Resources, Energy Distribution and Energy Gas). Each business unit has regulated and non-regulated operations. Based on this structure, management sets strategic goals, allocates resources and evaluates performance. The realignment resulted in the following nine reportable segments:

Table of Contents

Management’s Discussion and Analysis

Energy Resources

  Regulated operations include the power generation services of Detroit Edison, the Company’s electric utility. Electricity is generated from Detroit Edison’s numerous fossil plants or its nuclear plant and sold throughout Southeastern Michigan to residential, commercial, industrial and wholesale customers.
 
  Non-regulated

    Energy Services is comprised of various businesses that develop and manage energy-related assets and services. Such projects include coke production, synfuels production, independent power plants, on-site energy projects and cogeneration facilities. The economic viability of synfuels projects is tied to their generation of alternate fuels tax credits.
 
    Wholesale Marketing & Trading consists of the electric and gas marketing and trading operations of DTE Energy Trading Company and the natural gas marketing and trading operations of DTE Enterprises, which was acquired as part of the MCN Energy merger. Wholesale Marketing & Trading enters into forwards, futures, swaps and option contracts as part of its trading strategy. Wholesale Marketing & Trading focuses on physical power marketing and structured transactions, as well as the enhancement of returns from its power plant, pipeline and storage assets.
 
    Other non-regulated operations consist of businesses involved in coal services and landfill gas recovery along with an independent generating unit.

Energy Distribution

  Regulated operations include the electric distribution services of Detroit Edison, and the electric transmission services of the International Transmission Company (ITC). Energy Distribution distributes electricity generated by Energy Resources and alternative electric suppliers to Detroit Edison’s 2.1 million residential, commercial and industrial customers. The transmission assets of ITC are operated by the Midwest Independent System Operator, a regional transmission operator.
 
  Non-regulated operations primarily consist of DTE Energy Technologies, businesses that market and distribute a broad portfolio of distributed generation products, provide application engineering, and monitor and manage system operations.

Energy Gas

  Regulated operations include gas distribution services primarily provided by MichCon, the Company’s gas utility that purchases, stores and distributes natural gas throughout Michigan to 1.2 million residential, commercial and industrial customers.
 
  Non-regulated operations include the exploration and production of gas and the gathering, processing and storing of gas. Certain pipeline and storage assets are used to support the Wholesale Marketing & Trading segment.

Corporate & Other includes administrative and general expenses, and interest costs of DTE Energy corporate that have not been allocated to the regulated and non-regulated businesses. Corporate & Other also includes various other non-regulated operations, including investments in new emerging energy technologies.

(1)   Based on average shares outstanding during the periods.

Energy Resources

Regulated earnings increased $8 million and $30 million during the 2002 third quarter and nine-month period, respectively, reflecting higher gross margins due to lower purchased power costs. The lower purchased power costs reflect favorable energy market prices in 2002. Mark to market accounting for forward and option contracts in 2001 impacted revenues and purchased power, resulting in a favorable impact on margins of $36 million in the 2001 third quarter, and an unfavorable impact on margins of $9 million in the 2001 nine-month period. Margins were also impacted by higher revenues due to greater cooling demand in the 2002 third quarter and the loss of revenues resulting from customers switching to alternative electric suppliers under the electric Customer Choice program. Revenues for the 2002 nine-month period also were reduced due to the impact of a 5% legislatively mandated, securitization based, rate reduction for commercial and industrial customers that began in April 2001. The higher gross

Management’s Discussion and Analysis

margins were partially offset by increased employee benefit costs and higher operations and maintenance expenses due to planned and unplanned reliability and maintenance work done to improve the production and availability of the generation fleet. Depreciation and amortization expense decreased in the nine-month period reflecting the extension of the amortization period from seven years to 15 years for certain regulatory assets that were securitized in 2001.

Non-regulated earnings increased $18 million and $2 million for the 2002 third quarter and nine-month period, respectively, reflecting increased contributions from the Energy Services segment. The increase in Energy Services’ earnings is primarily attributable to greater synfuel production. Partially offsetting the improvement in the 2002 nine-month period were reduced contributions from the Wholesale Marketing & Trading segment. See Note 10 for a discussion regarding the reclassification of revenues and fuel, purchased power and gas expenses.

Outlook — Electric restructuring will continue to result in increased competition in the electric generation business. Effective January 1, 2002, the electric Customer Choice program in Michigan was expanded to allow all electric customers to choose to purchase their electricity from suppliers other than their local utility. Detroit Edison expects to lose between 5% to 8% of retail sales in 2002 and between 10% to 15% of such sales in 2003 as a result of customers choosing to participate in the electric Customer Choice program. To the extent Detroit Edison experiences net stranded costs as a result of customers switching

Management’s Discussion and Analysis

to an alternative electric supplier, Michigan law allows the recovery of all amounts of such net stranded costs. Detroit Edison disagreed with the MPSC initial methodology for determining and recovering net stranded costs and has asked for rehearing, clarification and modification of the December 2001 order. In May 2002, the MPSC denied Detroit Edison’s request for rehearing and clarification on certain aspects of the order. In June 2002, Detroit Edison filed a claim of appeal of the December 2001 MPSC order with the Michigan Court of Appeals.

In May 2002, Detroit Edison filed a new net stranded cost case with the MPSC that seeks to refine the methodology approved by the MPSC in December 2001 and calculates actual net stranded costs for 2000 and 2001. The MPSC Staff and interveners submitted their net stranded cost filings in November 2002. Detroit Edison expects to record 2002 net stranded costs as a regulatory asset with the offsetting entry reducing expense in the fourth quarter of 2002. See Note 4.

Energy Distribution

Regulated earnings increased $14 million and $16 million during the 2002 third quarter and nine-month period, respectively, due primarily to higher operating revenues which were partially offset by increased operation and maintenance expenses. Operating revenues increased due primarily to higher residential sales attributable to greater cooling demand. The increased operation and maintenance expenses are attributable to heat-related maintenance expenses due to prolonged periods of above normal temperatures and the related stress placed on the distribution system, higher employee benefit costs, and expenses associated with restoring power to customers who lost service during two storms in the 2002 nine-month period.

Management’s Discussion and Analysis

Non-regulated results declined $1 million and $3 million during the 2002 third quarter and nine-month period, respectively, due primarily to expenses associated with the establishment of new sales offices in the distributed generation business.

Outlook — Regulated electric system deliveries are expected to continue to increase for the remainder of 2002 and into 2003 due to the economic recovery. Operating results will vary as a result of various external factors such as weather, changes in economic conditions and the severity and frequency of storms. As a result of the continued restructuring of the electric industry, DTE Energy is in negotiations to sell ITC and expects to reach an agreement in the fourth quarter of 2002. The sale is expected to close in the first quarter of 2003.

Energy Gas

Regulated had a loss of $23 million for both the 2002 and 2001 third quarters, and had income of $30 million for the 2002 nine-month period compared to losses of $23 million in the comparable 2001 period. Due to the seasonal nature of the gas utility business, MichCon typically records third quarter losses. The significant improvement in the 2002 nine-month period reflects the operations of MichCon that were acquired in conjunction with the MCN Energy merger in May 2001. Accordingly, the 2001 nine-month period only includes MichCon’s operations for four months.

Non-regulated earnings were $6 million for both the 2002 and 2001 third quarter, and $20 million for the 2002 nine-month period compared to earnings of $8 million for the comparable 2001 periods. The results reflect the operations of the gas exploration and production business, and pipeline and processing activities. The non-regulated operations were also acquired in conjunction with the MCN Energy merger in May 2001, and were part of DTE Energy’s operations for only four months in the 2001 nine-month period.

Management’s Discussion and Analysis

Outlook — In December 2001, the MPSC issued an order that continues the gas Customer Choice program on a permanent and expanding basis. Beginning April 1, 2002, up to 40% of customers can elect to purchase gas from suppliers other than MichCon. Beginning in April 2003, up to 60% of customers could participate and beginning April 2004, all 1.2 million of MichCon’s gas customers could choose to participate. The MPSC also approved the use of deferred accounting for the recovery of implementation costs of the gas Customer Choice program. As of September 2002, approximately 187,000 customers are participating in the gas Customer Choice program. Since MichCon continues to transport and deliver the gas to the participating customers’ premises at prices comparable to margins earned on gas sales, customers switching to other suppliers have little impact on MichCon’s earnings.

Weather is the most significant factor that will effect Energy Gas’ sales.

Corporate & Other

Corporate & Other had income of $12 million and a loss of $30 million in the 2002 third quarter and nine-month period, respectively, compared to a loss of $26 million and $45 million in the comparable 2001 periods. The changes were due primarily to a favorable adjustment in the effective income tax rate. The income tax provisions of the segments are determined on a standalone basis. Corporate & Other records necessary adjustments in order that the consolidated income tax expense during the quarter reflects the estimated calendar year 2002 effective rate.

Operating Activities

Net cash from operating activities increased $88 million during the 2002 nine-month period as compared to the same 2001 period. The increase reflects an $83 million improvement in net income, after adjusting for non-cash items (depreciation, depletion and amortization, and merger and restructuring charges), and a $5 million improvement in working capital and other requirements. The working capital requirements reflect a significant decline in accounts payable balances in 2001, to more normalized levels, offset by an increase in gas inventories, electric customer account receivable balances and taxes paid. Gas inventories reflect the seasonal requirements in the latter half of the year of the gas business where cash is used to finance

Management’s Discussion and Analysis

increases in gas storage balances. Electric receivables reflect the seasonality of the electric utility industry where receivable balances were driven higher by the hot 2002 third quarter weather. Additionally, cash flow was negatively impacted by the under-recovery of gas costs totaling $18 million, as part of the GCR mechanism implemented in January 2002, where MichCon is allowed to recover its prudently incurred gas costs. Any remaining balance at year-end will be trued-up as part of 2002’s GCR reconciliation process.

Investing Activities

Net cash used for investing activities decreased $1.42 billion during the 2002 nine-month period as compared to the same 2001 period. The decrease is primarily due to the acquisition of MCN Energy in the 2001 nine-month period and a decrease in regulated and non-regulated plant and equipment expenditures.

Financing Activities

Net cash from financing activities decreased $1.71 billion during the 2002 nine-month period as compared to the same 2001 period. The decrease is primarily due to the issuance of $1.75 billion of securitization bonds in March 2001 and the issuance of $1.35 billion of long-term debt to finance the cash consideration portion of the acquisition of MCN Energy.

In April 2002, DTE Energy issued $200 million of 6.65% senior notes due 2009. The proceeds were used to retire MCN Energy Enterprises Remarketed Securities that had an aggregate principal amount of $100 million, and to reduce short-term borrowings.

In June 2002, DTE Energy issued 6.9 million equity security units at $25 per unit. An equity security unit consists of a stock purchase contract and a senior note of DTE Energy. DTE Energy used the net proceeds of $166.9 million from this issuance for general corporate purposes, including the repayment of short-term borrowings.

In June 2002, DTE Energy also issued 6.325 million shares of common stock at $43.25 per share, grossing $273.6 million. Net proceeds from the common stock offering were $265 million and are recorded in the accompanying consolidated statement of shareholders’ equity.

In October 2002, DTE Energy, Detroit Edison and MichCon entered into separate revolving credit facilities with a syndicate of banks totaling $1.2 billion. See Note 7.

Also in October 2002, Detroit Edison issued $450 million of senior notes collateralized by its General and Refunding Mortgage Bonds.

Outlook — DTE Energy, Detroit Edison and MichCon have effective shelf registrations with the SEC that allow for the issuance of up to a combined amount of $1.9 billion of debt and equity securities.

Detroit Edison expects to refinance approximately $90 million and issue approximately $40 million of tax exempt revenue bonds in the fourth quarter of 2002.

DTE Energy expects capital investments and expenditures in 2002 totaling approximately $950 million to $1 billion, of which approximately $200 million will be in the non-regulated businesses and the remaining balance will be in the regulated electric and gas operations.

The proposed level of investments in future years is expected to be financed primarily with internally generated funds, including proceeds received from the sale of non-strategic assets. DTE Energy will continue to evaluate its portfolio of assets and investments. The Company will evaluate divesting of assets and investments that do not meet certain return criteria or are not consistent with its strategic direction to maximize shareholder value.

Management’s Discussion and Analysis

The Company’s capitalization objective is to maintain its credit ratings through a strong balance sheet. It is management’s opinion that DTE Energy and its subsidiaries will have sufficient capital resources, both internal and external, to meet anticipated capital requirements.

PENSION AND POSTRETIREMENT COSTS

The Company’s costs of providing pension and postretirement benefits are dependent upon a number of factors, such as the rates of return on plan assets, the discount rate and the rate of increase in health care costs. The market value of plan assets has been affected by sharp declines in the equity market since 2000. As a result, at December 31, 2002, the Company could be required to recognize an additional minimum pension liability as prescribed by SFAS No. 87 “Employers’ Accounting for Pensions” and SFAS No. 132 “Employers’ Disclosures about Pensions and Postretirement Benefits.” The offset to any liability would be recorded as a reduction in shareholders’ equity, net of tax, or as a regulatory asset. The additional minimum pension liability and related accounting entries would be reversed on the balance sheet in future periods if the fair value of plan assets exceeds the accumulated pension benefit obligations. The additional minimum pension liability recorded, if any, will depend upon actual asset returns and interest rates in 2002, but could exceed $500 million pre-tax ($325 million after tax). The recording of any minimum pension liability would not affect net income or cash flow in 2002. Pension and postretirement costs and pension cash funding requirements could increase in future years without a substantial recovery in the equity markets. It is estimated that the increase in 2003 pension and postretirement costs could range from $90 million-$140 million, pretax, depending on actual plan asset returns, the discount rate and other actuarial assumptions that will not be determined until December 31, 2002. The Company will initiate cost saving strategies to significantly offset the earnings impact of higher pension and postretirement costs.

ENVIRONMENTAL MATTERS

EPA ozone transport regulations and new air quality standards relating to ozone and particulate air pollution will impact the Company. Detroit Edison has spent approximately $409 million through September 2002 and estimates that it will incur an additional $400 to $450 million of future capital expenditures over the next five years to comply.

NEW ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board (FASB) issued new accounting pronouncements concerning business combinations, goodwill and other intangible assets, asset retirement obligations, impairment or disposal of long-lived assets and energy trading contracts. See Note 10 for a discussion of the Company’s evaluation of the adoption of these new accounting pronouncements.

The “Prices from Quotes” category represents the Company’s positions for which forward price curves were developed using published NYMEX exchange prices and over the counter (OTC) gas and power quotes. The NYMEX currently publishes gas futures prices for the next six years.

The “Prices from external sources” category represents the Company’s forward positions in power at points for which OTC broker quotes are not always directly available. The Company values these positions against internally developed forward market price curves that are constantly validated and recalibrated against OTC broker quotes for closely correlated points. This category also includes “strip” transactions whose prices are obtained from external sources and then modeled to daily or monthly prices as appropriate.

Quantitative and Qualitative Disclosures about Market Risk

Commodity Price Risk

Risk Management Activities

DTE Energy is subject to commodity price risk in conjunction with the anticipated purchase of electricity to meet reliability obligations. Exposure to commodity price risk arises from market fluctuations in commodity prices.

To limit the sensitivity to commodity price fluctuations, DTE Energy has entered into a series of forward electricity contracts and option contracts.

The Company is also exposed to the risk of market price fluctuations on gas sale and purchase contracts, gas production and gas inventories. To manage this risk, the Company uses natural gas futures, options, forwards and swap agreements.

The Company performed a sensitivity analysis to calculate the impact of changes in fair values utilizing applicable forward commodity rates in effect at September 30, 2002. The Company estimates that if commodity prices were 10% higher or lower, the net fair value of commodity contracts would decrease $2.1 million and increase $2.1 million, respectively.

Trading Activities

Wholesale Marketing & Trading trades electricity, gas and related fuels, in addition to providing price risk management services using energy commodity derivatives. Wholesale Marketing & Trading performed a sensitivity analysis to calculate the impact of changes in fair values utilizing applicable forward commodity rates in effect at September 30, 2002. The Company estimates that if commodity prices were 10% higher or lower, the net fair value of commodity contracts would decrease $11.2 million and increase $14.1 million, respectively. See Note 10 for information regarding changes in accounting for energy trading activities.

DTE ENERGY COMPANY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1 — GENERAL

These consolidated financial statements should be read in conjunction with the notes to consolidated financial statements included in the 2001 Annual Report to the Securities and Exchange Commission on Form 10-K.

The accompanying consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America. In connection with their preparation, management makes estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

The consolidated financial statements are unaudited, but in the opinion of the Company’s management, include all adjustments necessary for a fair statement of the results for the interim periods. Financial results for this interim period are not necessarily indicative of results that may be expected for any other interim period or for the fiscal year.

Certain prior year balances have been reclassified to conform to the current year’s presentation.

NOTE 2 — MCN ENERGY ACQUISITION

On May 31, 2001, the Company completed the acquisition of MCN Energy by acquiring all of its outstanding shares of common stock for a combination of cash and shares of the Company’s common stock. The Company purchased the outstanding common stock of MCN Energy for $2.3 billion and assumed existing MCN Energy debt and preferred securities of $1.5 billion.

The Company accounted for the acquisition using the purchase method. The excess purchase price over the fair value of net assets acquired totaled $2.1 billion and was classified as goodwill. The Company began amortizing goodwill on June 1, 2001, on a straight-line basis using a 40-year life. In accordance with the adoption of SFAS No. 142, “Goodwill and Other Intangible Assets,” on January 1, 2002, the amortization of goodwill ceased, and is tested for impairment on an annual basis.

NOTE 3 — MERGER AND RESTRUCTURING CHARGES

On May 31, 2001, the Company completed the acquisition of MCN Energy. The Company incurred merger-related charges and restructuring charges associated with the acquisition. The merger-related charges of $7 million ($5 million after tax) in the 2001 third quarter and $25 million ($16 million after tax) in the 2001 nine-month period, consisted primarily of system integration, relocation, legal, accounting and consulting costs. Restructuring charges of $5 million ($3 million after tax) in the 2001 third quarter and $241 million ($157 million after tax) in the 2001 nine-month period, were primarily associated with a work force reduction plan. The plan included early retirement incentives along with voluntary separation arrangements for 1,186 employees, primarily in overlapping corporate support functions. The merger and restructuring costs had the effect of decreasing earnings by $12 million ($8 million after tax) and $266 million ($173 million after tax) for the 2001 third quarter and nine-month period, respectively.

NOTE 4 — REGULATORY MATTERS

Electric Industry Restructuring

As required by 2000 Public Act (PA) 141, the MPSC conducted a proceeding to develop a methodology for calculating the net stranded costs associated with electric Customer Choice. In a December 2001 order, the MPSC determined that Detroit Edison could recover net stranded costs associated with the fixed cost component of its electric generation operations. Specifically, there would be an annual filing with the MPSC comparing the actual revenues associated with the fixed cost component of its generation services to the revenue requirement for the fixed cost component of those services, inclusive of an allowance for the cost of capital. Any resulting shortfall in recovery, net of mitigation, would be considered a net stranded cost. The MPSC, in its December 2001 order, also determined that Detroit Edison had no stranded costs in 2000 and

23


Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

consequently established a zero net stranded cost transition charge for billing purposes in 2002. The MPSC authorized Detroit Edison to establish a regulatory asset to defer recovery of its incurred stranded costs after review in a subsequent annual net stranded cost proceeding. The MPSC also determined that Detroit Edison should provide a full and offsetting credit for the securitization and tax charges applied to electric Customer Choice bills in 2002 and maintained an additional credit on bills equivalent to the 5% rate reduction benefiting full service customers, both funded by savings derived from securitization. The December 2001 order when combined with lower wholesale power prices has encouraged additional customer participation in the electric Customer Choice program and has resulted in the loss of margins attributable to generation services. In May 2002, the MPSC denied Detroit Edison’s request for rehearing and clarification. In June 2002, Detroit Edison filed an appeal of the MPSC order at the Michigan Court of Appeals, challenging the legality of specific aspects of the MPSC order.

In May 2002, Detroit Edison submitted its 2002 net stranded cost filing with the MPSC. The filing provides refinements to the MPSC Staff’s calculation of net stranded costs that was adopted in the December 2001 order, seeks more timely recovery of net stranded costs, and addresses issues raised by the continuation of securitization offsets and rate reduction equalization credits. Detroit Edison’s filing supports the following conclusions: (i) Detroit Edison had no net stranded costs in 2000 and $13 million of recoverable net stranded costs attributable to electric Customer Choice in 2001; (ii) Detroit Edison requested recovery of 2001 net stranded costs through the use of excess residual securitization savings; (iii) Detroit Edison expects to incur additional net stranded costs in 2002 and 2003 as a result of increased electric Customer Choice participation; and (iv) recommended that a pro-forma or forward looking transition charge be approved for billing during the remainder of 2002 and for 2003 to eliminate the time lag between the occurrence and recovery of net stranded costs inherent in the methodology approved in the December 2001 order. In November 2002, the MPSC Staff and other interveners submitted their 2002 net stranded cost filings. Detroit Edison expects to record 2002 net stranded costs as a regulatory asset with the offsetting entry reducing expense in the fourth quarter of 2002.

In another December 2001 order, the MPSC finalized the prices, terms and conditions contained in the Retail Access Service Tariff (RAST). Detroit Edison requested rehearing and clarification on certain aspects of the order. In an order issued in April 2002, the MPSC modified its December 2001 order approving Detroit Edison’s RAST and reduced the requirements imposed on Detroit Edison in the December 2001 order concerning meter installation, meter reading and computer system enhancements for customers that elect to participate in the electric Customer Choice program.

In several orders issued in June 2000, the MPSC determined that adjusting rates for changes in fuel and purchased power expenses through continuance of the PSCR clause would be inconsistent with the rate freeze required by PA 141. Detroit Edison was not permitted to collect the 1998 PSCR under-recovery of $9 million, plus accrued interest of $3 million. Also, Detroit Edison was not required to refund approximately $55 million of liabilities for over-recoveries of PSCR expenses for 1999 and 2000, and disallowances under the Fermi 2 performance standard mechanism. In January and March 2002, the Michigan Court of Appeals rejected appeals and motions for rehearing filed by parties opposing the MPSC’s actions in this proceeding. In March 2002, the Michigan Attorney General applied for leave to appeal at the Michigan Supreme Court. The court has not yet determined whether or not it will hear the case.

Detroit Edison is unable to predict the outcome of the regulatory matters discussed herein. Resolution of these matters is dependent upon future MPSC orders, which may impact the financial position, results of operations and cash flows of Detroit Edison.

Gas Industry Restructuring

Through December 2001, MichCon was operating under an MPSC-approved Regulatory Reform Plan which included a comprehensive experimental three-year Customer Choice program, a Gas Sales Program and an income sharing mechanism. MichCon returned to the gas cost recovery (GCR) mechanism in January 2002 when the Gas Sales Program expired. Under the GCR mechanism, the gas commodity component of MichCon’s gas sales rates is designed to recover the actual costs of reasonably and prudently incurred gas purchases. In December 2001, the MPSC issued an order that permitted MichCon to implement GCR factors up to $3.62 per Mcf for January 2002 billings and up to $4.38 per Mcf for the remainder of 2002. The order also allowed MichCon to recognize a regulatory asset of approximately $14 million representing the difference between the $4.38 factor and the $3.62 factor for volumes that were unbilled at December 31, 2001. The regulatory asset will be subject to the 2002 GCR reconciliation process. As of September 30, 2002, MichCon has accrued a $33 million regulatory asset representing the under-recovery of actual gas costs incurred. In July 2002, in response to a petition for rehearing filed by the Michigan Attorney General, the MPSC directed the parties to address MichCon’s implementation of the December 2001 order and the impact of that implementation on rates charged to MichCon’s customers. Also, in July 2002, an MPSC Administrative Law Judge (ALJ) issued a Proposal for Decision on MichCon’s 2002 GCR plan case. In that decision the ALJ recommended adoption of the MPSC Staff’s proposed $26.5 million reduction in gas cost due to MichCon’s decision to utilize storage gas during 2001 that resulted in a gas inventory decrement for the 2001 calendar year. MichCon cannot predict the outcome and has not accrued an amount related to this matter.

On September 27, 2002, MichCon filed for approval of its 2003 GCR Plan. MichCon is requesting a maximum GCR factor of $4.14 per Mcf to be effective in monthly bills beginning with the January 2003 billing month. MichCon’s proposed 2003 rate is $0.24 per Mcf less than the current maximum 2002 GCR factor.

In December 2001, the MPSC also approved MichCon’s application for a voluntary, expanded permanent Customer Choice program, which would replace the experimental program that expired in March 2002. Effective April 2002, up to 40% of MichCon’s customers could elect to purchase gas from suppliers other than MichCon. Effective April 2003, up to 60% of customers would be eligible and by April 2004, all of MichCon’s 1.2 million customers can participate in the program. The MPSC also approved the use of deferred accounting for the recovery of implementation costs of the Customer Choice program. As of September 2002, approximately 187,000 customers are participating in the Customer Choice program.

Through December 2001, MichCon was operating under an MPSC-approved Regulatory Reform Plan which included an income sharing mechanism. The income sharing mechanism allowed customers to share in profits when actual returns on equity from utility operations exceed predetermined thresholds. Based on the MPSC approved formula, MichCon believes that no income sharing is required in 2001. In July 2002, the MPSC issued an order regarding MichCon’s 2001 income sharing. The MPSC ordered a hearing be held to determine the issue of the appropriate treatment of $766,000 of pipeline refunds received by MichCon during 2001. MichCon has made a filing regarding this matter and awaits further action by the MPSC.

MichCon is unable to predict the outcome of the regulatory matters discussed herein. Resolution of these matters is dependent upon future MPSC orders, which may impact the financial position, results of operations and cash flows of MichCon.

Other

In accordance with a November 1997 MPSC order, Detroit Edison reduced rates by $53 million annually to reflect the scheduled reduction in the revenue requirement for Fermi 2. The $53 million reduction was effective in January 1999. In addition, the November 1997 MPSC order authorized the deferral of $30

25


Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

million of storm damage costs and amortization and recovery of the costs over a 24-month period commencing January 1998. After various legal appeals, the Michigan Court of Appeals remanded the matter to the MPSC. In December 2000, the MPSC issued an order reopening the case for hearing. The parties in the case have agreed to a stipulation of fact and waiver of hearing. In June 2002, the MPSC issued an order modifying in part, and reaffirming in part, previous orders that authorized Detroit Edison to amortize and collect in rates the storm damage costs incurred in 1997. The MPSC modified its 1997 order regarding the calculation of the storm damage costs, and in doing so ordered Detroit Edison to refund approximately $1.5 million after January 1, 2004. The 2004 refund will also include interest accrued from January 1, 2000 at Detroit Edison’s authorized rate of return. In July 2002, the Michigan Attorney General filed an appeal with the Michigan Court of Appeals regarding the June 2002 MPSC order.

The Company is unable to predict the outcome of the regulatory matters discussed herein. Resolution of these matters is dependent upon future MPSC orders, which may impact the financial position, results of operations and cash flows of the Company.

NOTE 5 — PREFERRED SECURITIES OF SUBSIDIARIES

In January 2002, DTE Energy Trust I, a wholly owned trust of the Company, issued $180 million of 7.8% Trust Preferred Securities with a liquidation value of $25 per share due February 2032. The earliest date the securities can be redeemed is February 2007. The proceeds were used to redeem 8-5/8% Trust Originated Preferred Securities and 9-3/8% Redeemable Cumulative Preferred Securities in February 2002.

NOTE 6 — DEBT AND EQUITY TRANSACTIONS

Long-term Debt

During the first nine months of 2002, DTE Energy issued long-term debt consisting of:

    $200 million of senior notes bearing interest at 6.65 % and maturing in 2009. The proceeds were used to retire MCN Energy Enterprises’ Remarketed Securities, which had an aggregate principal amount of $100 million, and to reduce short-term borrowings.
 
    $172.5 million of equity-linked debt securities (discussed below).

In October 2002, Detroit Edison issued $450 million of its senior notes ($225 million due 2012 at 5.20% and $225 million due 2032 at 6.35%). These notes are collateralized by Detroit Edison’s General and Refunding Mortgage Bonds.

During the first nine months of 2002, DTE Energy and its subsidiaries repaid $512 million of long-term debt securities.

Equity-Linked Debt Securities

In June 2002, DTE Energy issued 6.9 million equity security units with gross proceeds from the issuance of $172.5 million. An equity security unit consists of a stock purchase contract and a senior note of DTE Energy. Under the stock purchase contracts, DTE Energy will sell shares of DTE Energy common stock in August 2005 for $172.5 million. The issue price and the exact number of DTE Energy common shares to be sold is dependent on the market value of a share in August 2005. The issue price will be not less than $43.25 or more than $51.90 per DTE Energy common share, with the corresponding number of

26


Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

shares issued of not more than 4.0 million or less than 3.3 million shares. DTE Energy is also obligated to pay the security unit holders a quarterly contract adjustment payment at an annual rate of 4.15% of the stated amount. DTE Energy has recorded the present value of the contract adjustment payments of $26 million in long-term debt with an offsetting reduction in shareholders’ equity. The liability is reduced as the contract adjustment payments are made.

Each senior note has a stated value of $25, pays an annual interest rate of 4.60% and matures in August 2007. The senior notes are pledged as collateral to secure the security unit holders’ obligation to purchase DTE Energy common stock under the stock purchase contracts. The security unit holders may satisfy their obligations under the stock purchase contracts by allowing the senior notes to be remarketed with proceeds being paid to DTE Energy as consideration for the purchase of stock under the stock purchase contracts. Alternatively, holders may choose to continue holding the senior notes and use cash as consideration for the purchase of stock under the stock purchase contracts.

Net proceeds from the equity security unit issuance totaled $166.9 million. Expenses incurred in connection with this issuance totaled $5.6 million and were allocated between the senior notes and the stock purchase contracts. The amount allocated to the senior notes was deferred and will be recognized as interest expense over the term of the notes. The amount allocated to the purchase contracts was charged to equity.

Cross Default Provisions

Substantially all of the net utility properties of Detroit Edison and MichCon are subject to the lien of mortgages. Should Detroit Edison or MichCon fail to timely pay their indebtedness under these mortgages, such failure will create cross defaults in substantially all of their respective indebtedness.

Debt Contingencies

DTE Energy has issued guarantees for the benefit of various non-regulated subsidiary transactions. In the event that DTE Energy’s credit rating is downgraded below investment grade, these guarantees would require DTE Energy to post cash or letters of credit valued at approximately $190 million at September 30, 2002. This estimated amount fluctuates based upon the provisions and maturities of the underlying agreements.

Common Stock

In June 2002, DTE Energy issued 6.325 million shares of common stock at $43.25 per share, grossing $273.6 million. Net proceeds from the offering were approximately $265 million. The total fees charged to equity relative to this issuance of common stock and the offering of the equity-linked debt securities described above, amounted to $9.1 million and $4.9 million, respectively.

NOTE 7 — SHORT-TERM CREDIT ARRANGEMENTS AND BORROWINGS

In October 2002, DTE Energy entered into a $470 million 364-day revolving credit facility and a $230 million three-year revolving credit facility with a syndicate of banks. These credit facilities may be utilized for general corporate borrowings, but primarily are intended to provide liquidity support for DTE Energy’s commercial paper program up to $700 million in amount. These agreements require the Company to maintain a debt to total capitalization ratio of no more than .65 to 1 and “earnings before interest, taxes, depreciation and amortization” (EBITDA) to interest ratio of no less than 2 to 1. Also, in October 2002, DTE Energy’s wholly-owned subsidiaries, Detroit Edison and MichCon, entered into similar revolving credit facilities. Detroit Edison entered into a $135 million, 364-day facility and a $65

27


Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

million, three-year facility. MichCon entered into a $200 million, 364-day facility and a $100 million, three-year facility. Should either Detroit Edison or MichCon have delinquent debt obligations of at least $25 million to any creditor, such delinquency will be considered a default under DTE Energy’s credit agreements.

NOTE 8 — EARNINGS PER SHARE

The Company reports both basic and diluted earnings per share. Basic earnings per share is computed by dividing income before accounting changes by the weighted average number of common shares outstanding during the period. Diluted earnings per share assumes the issuance of potentially dilutive common shares outstanding during the period and the repurchase of common shares that would have occurred with proceeds from the assumed issuance. These include the assumed exercise of stock options, vesting of non-vested stock awards and the issuance of common shares for performance share awards.

A reconciliation of both calculations for the 2002 and 2001 third quarter and nine-month period is presented in the table below. In each period presented, potentially dilutive securities have been excluded from the diluted EPS calculation since their inclusion would have been antidilutive based on average market prices during the respective periods.

Detroit Edison, MichCon and other Michigan utilities have asserted that Michigan’s valuation tables result in the substantial overvaluation of utility personal property. Valuation tables established by the Michigan State Tax Commission (STC) are used to determine the taxable value of personal property based on the property’s age. In November 1999, the STC approved new valuation tables that more accurately recognize the value of a utility’s personal property. The new tables became effective in 2000 and are currently used to calculate property tax expense. However, several local taxing jurisdictions have taken legal action attempting to prevent the STC from implementing the new valuation tables and have continued to prepare assessments based on the superseded tables. The legal actions regarding the appropriateness of the new tables were before the Michigan Tax Tribunal (MTT) which, in April 2002, issued its decision essentially affirming the validity of the STC’s new tables. In June 2002, petitioners in the case filed an appeal of the MTT’s decision with the Michigan Court of Appeals.

Other

DTE Energy subsidiaries purchase and sell electricity and gas to numerous companies operating in the steel, automotive, energy and retail industries. During 2001 and 2002, a number of customers have filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code, including certain Enron Corporation affiliates, National Steel Company and Bethlehem Steel Company. Management regularly reviews contingent matters relating to purchase and sale contracts and records provisions for amounts considered probable of loss. Management believes its previously accrued amounts are adequate for losses that are probable of occurring. The final resolution of these matters are not expected to have a material effect on the Company’s financial statements in the period they are resolved.

NOTE 10 — NEW ACCOUNTING PRONOUNCEMENTS

Business Combinations — Effective July 1, 2001, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 141, “Business Combinations.” SFAS 141 requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001. The adoption of SFAS 141 did not have an impact on the consolidated financial statements.

Goodwill and Other Intangible Assets — Effective January 1, 2002, the Company adopted SFAS No. 142, “Goodwill and Other Intangible Assets,” which addresses the financial accounting and reporting standards for the acquisition of intangible assets outside of a business combination and for goodwill and other intangible assets subsequent to their acquisition. This accounting standard requires that goodwill be separately disclosed from other intangible assets in the balance sheet, and no longer be amortized, but requires that goodwill be reviewed at least annually for impairment. The provisions of this accounting standard also require the completion of a transitional impairment test within six months of adoption, with any impairment treated as a cumulative effect of a change in accounting principle. The Company has completed the transitional goodwill impairment test and determined that no potential impairment existed at January 1, 2002.

In connection with the adoption of SFAS No. 142, the Company also reassessed the useful lives and the classification of identifiable intangible assets and determined that they continue to be appropriate. The Company’s intangible assets consist primarily of software and are subject to amortization. Intangible assets amortization expense was approximately $12 million and $35 million in the 2002 third quarter and nine-month period, respectively, compared with approximately $12 million and $35 million for the comparable 2001 periods. There were no material acquisitions of intangible assets during the nine-month period of 2002. The gross carrying amount and accumulated amortization of intangible assets at September 30, 2002 were $506 million and $304 million, respectively. Amortization expense of intangible assets is estimated to be $46 million annually for 2002 through 2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Asset Retirement Obligations — In June 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” This statement requires that the fair value of an asset retirement obligation be recognized in the period in which it is incurred. The associated asset retirement costs would be capitalized as part of the carrying amount of the long-lived asset. It would apply to legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development and (or) the normal operation of a long-lived asset. This statement is effective for financial statements issued for fiscal years beginning after June 15, 2002. The Company will adopt the statement in January 2003 and has not yet determined the impact of this statement on the consolidated financial statements.

Long-Lived Assets — On January 1, 2002, the Company adopted SFAS No. 144, “Accounting for the Impairment or Disposal of Long- Lived Assets.” SFAS No. 144 supersedes SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of,” but retains the fundamental provisions for recognizing and measuring impairment of long-lived assets to be held and used or disposed of by sale. The statement also supersedes the accounting and reporting provisions for the disposal of a segment of a business. SFAS No. 144 eliminates the conflict between accounting models for treating the disposition of long-lived assets that existed between SFAS No. 121 and the guidance for a segment of a business accounted for as a discontinued operation by adopting the methodology established in SFAS No. 121, and also resolves implementation issues related to SFAS No. 121. The adoption of the statement did not have an impact on the consolidated financial statements of the Company.

Energy Trading Contracts — The FASB's Emerging Issues Task Force (EITF) Issues No. 98-10, “Accounting for Contracts Involved in Energy Trading and Risk Management Activities,” permits either gross or net presentation of mark to market gains and losses on energy trading contracts (including those to be physically settled) in the consolidated statement of operations. Based on discussions held at the June 2002 meeting of the EITF and statements made by the SEC staff, the Company has concluded that net presentation is preferable. In the past the Company has presented such amounts on a gross basis. As of September 30, 2002 the Company presented such amounts on a net basis and all presented prior periods have been reclassified to be consistent.

The table below details the impact of the change in reporting gains and losses on energy trading contracts on the Company’s consolidated operating revenues and fuel, purchased power and gas expenses. This reclassification had no impact on margins and net income.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Under EITF Issue No. 98-10, companies were required to use mark to market accounting for contracts utilized in energy trading activities. With the rescission of Issue No. 98-10, energy trading contracts must now be reviewed to determine if they meet the definition of a derivative under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended. SFAS No. 133 requires all derivatives to be recognized in the statement of financial position as either assets or liabilities measured at their fair value and sets forth conditions in which a derivative instrument may be designated as a hedge. SFAS No. 133 also requires that changes in the fair value of derivatives be recognized in earnings unless specific hedge accounting criteria are met. Energy trading contracts not meeting the definition of a derivative would be accounted for under settlement accounting, effective October 25, 2002 for new contracts and effective January 1, 2003 for existing contracts.

Additionally, inventory utilized in energy trading activities accounted for under the fair value method of accounting as prescribed by Accounting Research Bulletin 43 will no longer be permitted. DTE Energy’s Wholesale Marketing & Trading segment uses gas inventory in its trading operations and will switch to an acceptable inventory accounting method as required, which is expected to be in the fourth quarter of 2002 or the first quarter of 2003.

The Company is evaluating the impact of the prohibition on the use of the fair value inventory method, and the rescinding of EITF No. 98-10. The Company has not yet determined the impact of these developments on the consolidated financial statements.

INDEPENDENT ACCOUNTANTS’ REPORT

To the Board of Directors and Shareholders of
DTE Energy Company:

We have reviewed the accompanying condensed consolidated statement of financial position of DTE Energy Company and subsidiaries as of September 30, 2002, and the related condensed consolidated statement of operations for the three-month and nine-month periods ended September 30, 2002 and 2001, and the condensed consolidated statement of cash flows for the nine-month periods ended September 30, 2002 and 2001, and the condensed consolidated statement of changes in shareholders’ equity for the nine-month period ended September 30, 2002. These financial statements are the responsibility of DTE Energy Company’s management.

We conducted our review in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures to financial data and of making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the United States of America, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to such condensed consolidated financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with auditing standards generally accepted in the United States of America, the consolidated statement of financial position of DTE Energy Company and subsidiaries as of December 31, 2001, and the related consolidated statements of operations, cash flows and changes in shareholders’ equity for the year then ended (not presented herein); and in our report dated February 26, 2002 (September 17, 2002 as to Note 20), we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated statement of financial position as of December 31, 2001 is fairly stated, in all material respects, in relation to the consolidated statement of financial position from which it has been derived.
