Management’s Narrative Analysis of the Results of Operations
The Management’s Narrative Analysis of the Results of Operations discussion for MichCon is presented in accordance with General Instruction H(2)(a) of Form 10-Q.
Certain items reflected in the accompanying consolidated financial statements have been eliminated at DTE Energy as a result of purchase accounting adjustments.
Factors impacting income: MichCon’s net income increased $63 million. The results reflect increased rates and the impacts in 2005 of the MPSC’s April 2005 gas cost recovery and final gas rate orders, partially offset by the effects of milder winter weather in 2006.
The MPSC final gas rate order disallowed recovery of 90% of the costs of a computer billing system that was in place prior to DTE Energy’s acquisition of MCN Energy in 2001. MichCon impaired this asset by approximately $42 million in the first quarter of 2005.

Gross margins increased $32 million in the first quarter of 2006 compared to the prior year. Gross margins in 2006 were favorably affected by higher base rates as a result of the April 2005 final gas rate order, and revenue associated with the uncollectible expense tracking mechanism authorized by the MPSC, partially offset by the effects of milder winter weather in 2006 and customer conservation. In April 2005, the MPSC issued an order in the 2002 GCR reconciliation case that disallowed $26 million representing unbilled revenues at December 2001. We recorded the impact of the disallowance during the first quarter of 2005.

Operation and maintenance expense remained the same due to DTE Energy parent company no longer allocating merger-related interest to MichCon effective in April 2005 and the 2005 disallowance of certain environmental costs due to the April 2005 final gas rate order, partially offset by increased uncollectible accounts receivables expense, reflecting higher past due amounts attributable to an increase in gas prices, continued weak economic conditions and inadequate government-sponsored assistance for low-income customers. The 2005 final gas rate order provided revenue for an uncollectible expense tracking mechanism to mitigate some of the effect of increasing uncollectible expense.
Asset (gains) and losses, net decreased $48 million due to the 2005 disallowances of approximately $42 million of costs related to a computer billing system and $6 million of certain computer equipment and related depreciation resulting from the April 2005 final gas rate order.
Income taxes increased $17 million primarily due to higher income, partially offset by a lower effective tax rate in 2006.
Outlook – Operating results are expected to vary as a result of factors such as regulatory proceedings, weather, changes in economic conditions, customer conservation, usage declines due to technology/efficiency, cost containment efforts and process improvements. Higher gas prices and economic conditions have resulted in continued pressure on receivables and working capital requirements partially mitigated by the GCR mechanism. We believe our allowance for doubtful accounts is based on reasonable estimates. In the April 2005 final gas rate order, the MPSC adopted MichCon’s proposed tracking mechanism for uncollectible accounts receivable. Each year, MichCon will file an application comparing its actual uncollectible expense for the prior calendar year to its designated revenue recovery of approximately $37 million. Ninety percent of the difference will be refunded or surcharged after an annual reconciliation proceeding before the MPSC.
CONTROLS AND PROCEDURES
(a) Evaluation of disclosure controls and procedures
Management of the Company carried out an evaluation, under the supervision and with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of March 31, 2006, which is the end of the period covered by this report. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that such controls and procedures are effective in ensuring that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Due to the inherent limitations in the effectiveness of any disclosure controls and procedures, management cannot provide absolute assurance that the objectives of its disclosure controls and procedures will be attained.
(b) Changes in internal control over financial reporting
There has been no change in the Company’s internal control over financial reporting during the quarter ended March 31, 2006 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Michigan Consolidated Gas Company
Notes to Consolidated Financial Statements (Unaudited)
NOTE 1 — GENERAL
These consolidated financial statements should be read in conjunction with the notes to the consolidated financial statements included in our 2005 Annual Report on Form 10-K.
The accompanying consolidated financial statements are prepared using accounting principles generally accepted in the United States of America. These accounting principles require us to use estimates and assumptions that impact the reported amounts of assets, liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities. Actual results may differ from those estimates.
The consolidated financial statements are unaudited, but in our opinion, 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 the results that may be expected for any other interim period or for the fiscal year.
Asset Retirement Obligations
We have recorded asset retirement obligations in accordance with SFAS No. 143, Accounting for Asset Retirement Obligations and FASB Interpretation FIN No. 47, Accounting for Conditional Asset Retirement Obligations, an interpretation of FASB Statement No. 143. We identified conditional retirement obligations for gas pipeline retirement costs. To a lesser extent, we have conditional retirement obligations at certain service centers, compressor and gate stations.
As to regulated operations, we believe that adoptions of SFAS No. 143 and FIN 47 result primarily in timing differences in the recognition of legal asset retirement costs that we are currently recovering in rates. We will be deferring such differences under SFAS No. 71, Accounting for the Effects of Certain Types of Regulation.
A reconciliation of the asset retirement obligation for the first quarter of 2006 follows:

Retirement Benefits and Trusteed Assets
MichCon sponsors a defined benefit retirement plan for eligible MichCon represented employees. MichCon also participates in a defined benefit retirement plan sponsored by Detroit Edison for its nonrepresented employees, which is treated as a plan covering employees of various affiliates of DTE Energy from the affiliates’ perspective. We are allocated income or an expense each year as a result of our participation in the DTE Energy Company Retirement Plan. Income was approximately $7 million for the three months ended March 31, 2006 and 2005 and is not reflected in the following table.

In its April 2005 final rate order, the MPSC approved the deferral of the non-capitalized portion of our negative pension expense. At March 31, 2006, we recorded a $19 million regulatory liability.

During the first quarter of 2006, we made a cash contribution of $20 million to our postretirement health care and life insurance plans.
Gas in Inventory
Gas inventory is priced on a last-in, first-out (LIFO) basis. In anticipation that interim inventory reductions will be replaced prior to year end, the cost of gas of net withdrawals from inventory is recorded at the estimated average purchase rate for the calendar year. The excess of these charges over the weighted average cost of the LIFO pool is credited to the gas inventory equalization account. During interim periods when there are net injections to inventory, the equalization account is reversed.
NOTE 2 – NEW ACCOUNTING PRONOUNCEMENTS
Stock-Based Compensation
Effective January 1, 2006, our parent company DTE Energy adopted SFAS No. 123(R), Share-Based Payment, using the modified prospective transition method. We receive an allocation of costs associated with stock compensation and the related impact of cumulative accounting adjustments.
Our allocation for the first quarter of 2006 for stock-based compensation expense was immaterial. The cumulative effect of the adoption of SFAS 123(R) also had an immaterial impact on our operations and maintenance expense. We have not restated any prior periods as a result of the adoption of SFAS 123(R).

In October 2005, the MPSC established emergency billing practices in effect for gas service rendered November 1, 2005 through March 31, 2006. These emergency rules apply to retail gas customers. The rule changes:
  •   lengthen the period of time before a bill is due once it is transmitted to the customer;
 
  •   prohibit shut off or late payment fees unless an actual meter read is made;
 
  •   limit the required monthly payment on a settlement agreement;
 
  •   increase the income level qualifying for shut-off protection and lower the payment required to remain on shut-off protection; and
 
  •   lessen or eliminate certain deposit requirements.
Uncollectible Expense Tracker Mechanism and Report of Safety and Training-Related Expenditures
In March 2006, MichCon filed an application with the MPSC for approval of its uncollectible expense tracking mechanism for 2005 and review of 2005 annual safety and training-related expenditures. This is the first filing MichCon has made under the uncollectible tracking mechanism, which was approved by the MPSC in April 2005 as part of MichCon’s last general rate case. MichCon’s 2005 base rates included $37 million for anticipated uncollectible expenses. Actual 2005 uncollectible expenses for Michcon totaled $60 million. The tracker mechanism allows MichCon to recover 90 percent of uncollectibles that exceeded that $37 million base. Under the formula prescribed by the MPSC, MichCon has asked to recover approximately $11 million in uncollectible expenses for 2005 pro-rated from May 2005 (when the mechanism took effect) through the end of 2005. If approved by the MPSC, the underrecovery will be recovered from customers through a monthly surcharge. MichCon reported that actual safety and training-related expenditures for the initial period exceeded the pro-rated expenditures in base rates and recommended no refund at this time.
Gas Cost Recovery Proceedings
2004 Plan Year — In September 2003, MichCon filed its 2004 GCR plan case proposing a maximum GCR factor of $5.36 per Mcf. MichCon agreed to switch from a calendar year to an operational year as a condition of its settlement in the 2003 GCR plan case. The operational GCR year runs from April to March of the following year. To accomplish the switch, the 2004 GCR plan reflected a 15-month transitional period, January 2004 through March 2005. Under this transition proposal, MichCon filed two reconciliations pertaining to the transition period; one in June 2004 addressing January through March 2004, one filed in June 2005 addressing the remaining April 2004 through March 2005 period and consolidating the two for purposes of the case. The June 2005 filing supported the $46 million under-recovery with interest MichCon had accrued for the period ending March 31, 2005. In March 2006, MPSC Staff filed testimony recommending an adjustment to the accounting treatment of the injected base gas remaining in the New Haven storage field when it was sold in early 2004 that would result in a $3 million reduction to MichCon’s accrued underrecovery. MichCon does not expect a final order before the third quarter of 2006.
2005-2006 Plan Year — In December 2004, MichCon filed its 2005-2006 GCR plan case proposing a maximum GCR factor of $7.99 per Mcf. The plan includes quarterly contingent GCR factors. These contingent factors allow MichCon to increase the maximum GCR factor to compensate for increases in gas market prices, thereby reducing the possibility of a GCR

under-recovery. In April 2005, the MPSC issued an order recognizing that Michigan law allows MichCon to self-implement its quarterly contingent factors. MichCon self-implemented quarterly contingent GCR factors of $8.54 per Mcf in July 2005 and $10.09 per Mcf in October 2005.
In response to market price increases in the fall of 2005, MichCon filed a petition to reopen the record in the case during September 2005. MichCon proposed a revised maximum GCR factor of $13.10 per Mcf and a revised contingent factor matrix. In its order issued October 6, 2005, the MPSC reopened the record in the case. On October 28, 2005, the MPSC approved an increase in the GCR factor to a cap of $11.3851 per Mcf for the period November 2005 through March 2006.
2006-2007 Plan Year – In December 2005, MichCon filed its 2006-2007 GCR plan case proposing a maximum GCR Factor of $12.15 per Mcf. The plan includes quarterly contingent GCR factors. These contingent factors, if approved by the MPSC, will allow MichCon to increase the maximum GCR factor to compensate for increases in market prices, thereby reducing the possibility of a GCR under-recovery.

We are unable to predict the outcome of the regulatory matters discussed herein. Resolution of these matters is dependent upon future MPSC orders and appeals, which may materially impact the financial position, results of operations and cash flows of the Company.
NOTE 4 – CONTINGENCIES
Environmental Matters
Contaminated Sites — Prior to the construction of major interstate natural gas pipelines, gas for heating and other uses was manufactured locally from processes involving coal, coke or oil. We own, or previously owned, 14 such former manufactured gas plant (MGP) sites. Investigations have revealed contamination related to the by-products of gas manufacturing at each site. In addition to the MGP sites, we are also in the process of cleaning up other contaminated sites. Cleanup activities associated with these sites will be conducted over the next several years.
In 1993, a cost deferral and rate recovery mechanism was approved by the MPSC for investigation and remediation costs incurred at former MGP sites in excess of this reserve. We employed outside consultants to evaluate remediation alternatives for these sites, to assist in estimating its potential liabilities and to review its archived insurance policies. As a result of these studies, we accrued an additional liability and a corresponding regulatory asset of $32 million during 1995. During 2005, we spent approximately $4 million investigating and remediating these former MGP sites. In December 2005, we retained multiple environmental consultants to estimate the projected cost to remediate each MGP site. We accrued an additional $9 million in remediation liabilities associated with two of our MGP sites, to increase the reserve balance to $33 million at December 31, 2005.
Any significant change in assumptions, such as remediation techniques, nature and extent of contamination and regulatory requirements, could impact the estimate of remedial action costs for the sites and affect the Company’s financial position and cash flows. However, we anticipate the cost deferral and rate recovery mechanism approved by the MPSC will prevent environmental costs from having a material adverse impact on our results of operations.

Personal Property Taxes
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. In January 2004, the Michigan Court of Appeals upheld the validity of the new tables. With no further appeal by the petitioners available, the MTT began to schedule utility personal property valuation cases for Prehearing General Calls. After a period of abeyance the MTT issued a scheduling order in a significant number of MichCon appeals that set litigation calendars for these cases extending into mid-2006. After an extended period of settlement discussions, a Memorandum of Understanding has been reached with six principals in the litigation and the Michigan Department of Treasury that is expected to lead to settlement of all outstanding property tax disputes on a global basis.
On December 8, 2005, executed Stipulations for Consent Judgment, Consent Judgments, and Schedules to Consent Judgment were filed with the MTT on behalf of MichCon and a significant number of the largest jurisdictions, in terms of tax dollars, involved in the litigation. The filing of these documents fulfilled the requirements of the global settlement agreement and resolves a number of claims by the litigants against each other including both property and non-property issues. The global settlement agreement resulted in an economic benefit to MichCon in 2005 that included the release of a litigation reserve.
Income Taxes
The Internal Revenue Service is currently conducting audits of MichCon as a component of the DTE Energy federal income tax returns for the years 2002 and 2003. The Company accrues tax and interest related to tax uncertainties that arise due to actual or potential disagreements with governmental agencies about the tax treatment of specific items. We believe that our accrued tax liabilities are adequate for all years.
Other Commitments
As of December 31, 2005, we were party to numerous long-term purchase commitments relating to a variety of goods and services required for our business. These agreements primarily consist of long-term gas purchase and transportation agreements. We estimate that these commitments will be approximately $1.7 billion through 2051. We also estimate that 2006 base level capital expenditures will be approximately $162 million. We have made certain commitments in connection with expected capital expenditures.
Bankruptcies
We sell gas and/or gas transportation and storage services to numerous companies operating in the steel, automotive, energy, retail and other industries. Certain of our customers have filed for bankruptcy protection under Chapter 11 of the U.S. Bankruptcy Code. We regularly review contingent matters relating to these customers and our sale contracts and we record

provisions for amounts considered at risk of probable loss. We believe our previously accrued amounts are adequate for probable losses. The final resolution of these matters is not expected to have a material effect on our financial statements.
Other
We are involved in certain legal, regulatory, administrative and environmental proceedings before various courts, arbitration panels and governmental agencies concerning matters arising in the ordinary course of business. These proceedings include certain contract disputes, environmental reviews and investigations, audits, inquiries from various regulators, and pending judicial matters. We cannot predict the final disposition of such proceedings. We regularly review legal matters and record provisions for claims that are considered probable of loss. The resolution of pending proceedings is not expected to have a material effect on our operations or financial statements in the period they are resolved.
