Item 1.       Not Applicable.

Item 2.       Acquisition or Disposition of Assets.

              On May 31, 2001, DTE Energy Company, a Michigan corporation (the
"Company"), and MCN Energy Group Inc., a Michigan corporation ("MCN"), completed
the merger between the Company and MCN as contemplated by the Agreement and Plan
of Merger, dated as of October 4, 1999 and as amended as of November 12, 1999
and as further amended as of February 28, 2001 (the "Amended Merger Agreement"),
among DTE, MCN and DTE Enterprises, Inc., a Michigan corporation and
wholly-owned subsidiary of DTE ("DTE Enterprises"). In accordance with the terms
and subject to the conditions set forth in the Amended Merger Agreement, MCN
merged with and into DTE Enterprises with DTE Enterprises as the surviving
corporation (the "Merger"). As a result of the merger, MCN is now a wholly-owned
subsidiary of DTE.

              At the time of the merger, each share of MCN common stock
outstanding immediately prior to the Effective Time (as defined in the Amended
Merger Agreement) was converted into the right to receive either (i) $24 in cash
or (ii) 0.715 of a share of DTE common stock, subject to the proration and
allocation and tax adjustment procedures set forth in the Amended Merger
Agreement and further described in the Company's Registration Statement on Form
S-4 dated April 9, 2001 (no. 333-89175).

              On May 30, 2001, DTE issued senior debt in an aggregate amount of
$1,350,000,000. Substantially all of the net proceeds from this offering were
used to fund the cash consideration for its merger with MCN.

              Prior to the Merger, MCN was an integrated energy company
primarily involved in natural gas production, gathering, processing,
transmission, storage and distribution and energy marketing. DTE and DTE
Enterprises intend to continue to use the majority of the assets of MCN for the
foregoing business purposes.

Items 3-6.    Not Applicable.

Items 7(a).   Financial Statements of Businesses Acquired.

              We incorporate by reference the documents filed with the SEC and
listed below:

              Audited consolidated financial statements of MCN, and the notes
related thereto, included on pages 61 through 117 of MCN's Annual Report on Form
10-K for the year ended December 31, 2000, filed on March 15, 2001. (File No.
1-10070)

              Unaudited consolidated financial statements of MCN, and the notes
related thereto, included on pages 20 through 43 of MCN's Quarterly Report on
Form 10-Q for the quarter ended March 31, 2001, filed on May 14, 2001. (File No.
1-10070)

Item 7(b).    Pro Forma Financial Information.

              The following unaudited pro forma information reflects the
historical combined condensed consolidated statements of income of DTE and MCN
after accounting for the merger as a purchase business combination. Accordingly,
the following information should be read together with the historical
consolidated financial statements and the related notes thereto, of both DTE and
MCN. The unaudited pro forma combined condensed consolidated statements of
income assume the merger became effective as of the beginning of the periods
presented.

              The following unaudited pro forma information does not include a
combined condensed consolidated balance sheet since the merger is reflected in
DTE's consolidated financial statements on Form 10-Q for the quarter ended June
30, 2001, filed on August 14, 2001.

              The information presented below is not necessarily indicative of
the results of operations that might have occurred had the merger actually
closed on January 1, 2000. The information is not necessarily indicative of the
future results of operations of DTE after the merger.

              The unaudited pro forma combined condensed consolidated statements
of income do not reflect the non-recurring costs and expenses associated with
integrating the operations of the two companies, nor any of the anticipated
recurring expense savings arising from the integration.

              Allocations included in the pro forma statements are preliminary
and may be revised up to one year from the date of merger due to fair value
adjustments of assets and liabilities. Accordingly, the final value of the
purchase price and its allocation may differ from the amounts shown in the
unaudited pro forma combined condensed consolidated statements of income that
follow.

              As of January 1, 2001, DTE and MCN adopted Statement of Financial
Accounting Standards (SFAS) No. 133 Accounting for Derivative Instruments and
Hedging Activities," as amended and interpreted.

                      NOTES TO UNAUDITED PRO FORMA COMBINED
                   CONDENSED CONSOLIDATED STATEMENTS OF INCOME


1.   Certain revenues and expenses of DTE and MCN have been reclassified.

2.   Routine sales and purchases between DTE and MCN are not material and have
not been eliminated in the Unaudited Pro Forma Combined Condensed Consolidated
Statements of Income.

3.   DTE applies the provisions of Accounting Principles Board Opinion (APB) No.
25, Accounting for Stock Issued to Employees, for its incentive compensation
plans. MCN applied the provisions of SFAS No. 123, Accounting for Stock-Based
Compensation, for its incentive compensation plans. The impact of adjusting
MCN's recorded compensation expense under SFAS No. 123 to the provisions of APB
No. 25 is not material, and therefore, is not reflected in the pro forma
adjustments.

4.   MCN reflects results of operations of MCN for five months ended May 31,
2001. DTE (As Reported) includes results of operations for MCN for the month of
June 2001.

5.   The Unaudited Pro Forma Combined Condensed Consolidated Statements of
Income are based on the following assumptions:

    (a)        Reflects the amortization of purchase price in excess of the
               amounts assigned to identifiable assets and liabilities of MCN
               using the straight-line method over 40 years. In accordance with
               the adoption of SFAS No. 142, "Goodwill and Other Intangible
               Assets", on January 1, 2002, the amortization of goodwill will
               cease and goodwill will be tested for impairment on an annual
               basis.

    (b)        Reflects the interest expense related to the issuance of $1.350
               billion in long-term debt of DTE to finance the cash
               consideration of the merger. Interest expense is assumed at
               7.37%, which includes the effect of the amortization of the
               merger debt hedges.

    (c)        Reflects the elimination of net gain and transition adjustments
               related to pension and other post-retirement benefits.

    (d)        Reflects adjustments to gains on MCN's sales of investments in
               joint ventures and other assets to reflect values that would have
               been assigned to such investments and assets in the allocation of
               the purchase price as of the beginning of the periods presented.

     (e)      Reflects adjustments for storage and transport costs.

     (f)      The estimated provision for income taxes related to the pro forma
              adjustments is based on the statutory federal income tax rate of
              35%. Amortization of goodwill has not been tax affected.
