CMS Energy Corporation
CMS ENERGY CORPORATION MANAGEMENT'S DISCUSSION AND ANALYSIS Energy Corporation
Management’s Discussion and Analysis
This MD&A is a consolidated report of CMS Energy and Consumers. The terms "we"“we” and "our"“our” as used in this report refer to CMS Energy and its subsidiaries as a consolidated entity, except where it is clear that such term means only CMS Energy. This MD&A has been prepared in accordance with the instructions to Form 10-Q and Item 303 of Regulation S-K. This MD&A should be read in conjunction with the MD&A contained in CMS Energy'sEnergy’s Form 10-K for the year ended December 31, 2006. EXECUTIVE OVERVIEW2006 and the Form 8-K filed June 4, 2007 amending CMS Energy is an energy company operating primarily in Michigan. We are the parent holding company of ConsumersEnergy’s 2006 financial statements to reflect certain discontinued operations resulting from recent asset sales.
Forward-looking statements and Enterprises. Consumers is a combination electric and gas utility company serving Michigan's Lower Peninsula. Enterprises, through various subsidiaries and equity investments, is engaged in domestic and international energy businesses including independent power production, electric distribution, and natural gas transmission, storage, and processing. We manage our businesses by the nature of services each provides and operate principally in three business segments: electric utility, gas utility, and enterprises. We earn our revenue and generate cash from operations by providing electric and natural gas utility services, electric power generation, and gas distribution, transmission, storage, and processing. Our businesses are affected primarily by: - weather, especially during the normal heating and cooling seasons, - economic conditions, primarily in Michigan, - regulation and regulatory issues that affect our electric and gas utility operations, - energy commodity prices, - interest rates, and - our debt credit rating. During the past several years, our business strategy has involved improving our consolidated balance sheet and maintaining focus on our core strength: utility operations and service. In April 2007, we sold Palisades to Entergy for $380 million. The final purchase price was subject to various closing adjustments resulting in us receiving $361 million. We also paid Entergy $30 million to assume ownership and responsibility for the Big Rock Independent Spent Fuel Storage Installation (ISFSI). We entered into a 15-year power purchase agreement with Entergy for 100 percent of the plant's current electric output. The sale resulted in an immediate improvement in our cash flow, a reduction in our nuclear operating and decommissioning risk, and an improvement in our financial flexibility to support other utility investments. The MPSC order approving the transaction requires that $255 million be credited to our retail customers through refunds applied over the remainder of 2007 and 2008. CMS-1 CMS Energy Corporation In 2007, we intend to complete the sale of our non-North American Enterprises assets. We plan to use the proceeds from these sales to retire debt and to invest in our utility business. In March 2007, we completed the sale of a portfolio of our businesses in Argentina and our northern Michigan non-utility natural gas assets to Lucid Energy for $130 million. In March 2007, we also sold our interest in El Chocon, an Argentine hydroelectric generating business, to Endesa, S.A. for $50 million. We used the cash proceeds to invest in our utility business and reduce debt. In April 2007, we entered into an agreement to sell CMS Energy Brasil S.A. for $211 million to CPFL Energia S.A., a Brazilian utility. The sale is expected to close by the end of the second quarter of 2007, subject to approval by the Brazilian national electric utility regulatory agency. In April 2007, we completed the sale of our ownership interest in SENECA and certain associated generating equipment to Petroleos de Venezuela, S.A. for $106 million. In May 2007, we completed the sale of our ownership interest in businesses in the Middle East, Africa, and India to TAQA for $900 million. We plan to use the proceeds to invest in our utility business and reduce debt. In addition, during 2007, we plan to conduct an auction to sell our GasAtacama combined gas pipeline and power generation businesses in Argentina and Chile, and our electric generating plant in Jamaica. For additional details on our planned asset sales, see the "Enterprises Outlook" section within this MD&A. In January 2007, we took an important step in our business plan by reinstating a dividend on our common stock after a four-year suspension at $0.05 per share. We paid $11 million in common stock dividends in February 2007. We also took steps toward resolving a long-outstanding litigation issue. In January 2007, we reached a preliminary agreement to settle two class action lawsuits related to round-trip trading by CMS MST. We believe that eliminating this business uncertainty is in the best interests of our shareholders. In the future, we will focus our strategy on: - continued investment in our utility business, - successful completion of announced asset sales, - reducing parent debt, and - growing earnings while controlling operating costs. As we execute our strategy, we will need to overcome a sluggish Michigan economy that has been hampered by negative developments in Michigan's automotive industry and limited growth in the non-automotive sectors of the state's economy. The return of ROA customer load has offset some of these negative effects. At March 31, 2007, alternative electric suppliers were providing 283 MW of generation service to ROA customers. This is 3 percent of our total distribution load and represents a decrease of 19 percent of ROA load compared to March 31, 2006. FORWARD-LOOKING STATEMENTS AND INFORMATION information
This Form 10-Q and other written and oral statements that we make contain forward-looking statements as defined in Rule 3b-6 under the Securities Exchange Act of 1934, as amended, Rule 175 under the Securities Act of 1933, as amended, and relevant legal decisions.

Executive Overview
CMS ENERGY CONSOLIDATED RESULTS OF OPERATIONS Energy is an energy company operating primarily in Michigan. We are the parent holding company of Consumers and Enterprises. Consumers is a combination electric and gas utility company serving Michigan’s Lower Peninsula. Enterprises, through various subsidiaries and equity investments, is engaged primarily in domestic independent power production. We manage our businesses by the nature of services each provides and operate principally in three business segments: electric utility, gas utility, and enterprises.
We earn our revenue and generate cash from operations by providing electric and natural gas utility services, electric power generation, and gas distribution, transmission, and storage. Our businesses are affected primarily by:
In Millions (except
weather, especially during the normal heating and cooling seasons,
economic conditions, primarily in Michigan,
regulation and regulatory issues that affect our electric and gas utility operations,
energy commodity prices,
interest rates, and
our debt credit rating.
During the past several years, our business strategy has involved improving our consolidated balance sheet and maintaining focus on our core strength: utility operations and service. As an indication of our commitment to our utility business, we have invested $650 million in Consumers during the first half of 2007.
We expect to complete the sale of our international Enterprises assets by the end of 2007. Proceeds from asset sales are used to retire debt and to invest in our utility business. Asset sales completed in 2007 include:
a portfolio of our businesses in Argentina and our northern Michigan non-utility natural gas assets to Lucid Energy for per share amounts) ------------------------ Three months ended$130 million in March 312007,

We have also entered into an agreement to sell our investment in Jamaica to AEI for $14 million, which we expect to close by the end of 2007.
We also made important progress at Consumers to reduce business risk and to meet the future needs of our customers. We sold Palisades to Entergy in April 2007 for $380 million. The final purchase price is subject to various closing adjustments resulting in us receiving $364 million as of June 30, 2007. The sale resulted in an immediate improvement in our cash flow, a reduction in our nuclear operating and decommissioning risk, and an improvement in our financial flexibility to support other utility investments.
After September 15, 2007, we expect to claim relief under the regulatory-out provision in the MCV PPA, thereby limiting our capacity and fixed energy payments to the MCV Partnership to the amounts that we collect from our customers. If we are successful in exercising the regulatory-out provision, the MCV Partnership may, under certain circumstances, have the right to terminate or reduce the amount of capacity sold under the MCV PPA, which could affect our need to build or purchase additional generating capacity.
We introduced our Balanced Energy Initiative, a comprehensive plan to meet customer energy needs over the next 20 years, in May 2007. The plan, as filed with the MPSC, is designed to meet the growing customer demand for electricity with energy efficiency, demand management, expanding the use of renewable energy, and developing new power plants to complement existing generating sources.
In May 2007, we entered an agreement to buy a 946 MW natural gas-fired power plant located in Zeeland, Michigan from Broadway Gen Funding LLC, an affiliate of LS Power Group, for $517 million. The purchase is subject to approvals from the MPSC and other regulatory bodies and is expected to close in early 2008.
We took an important step in our business plan in January 2007 by reinstating a quarterly dividend of $0.05 per share on our common stock, after a four-year suspension. We paid $11 million in common stock dividends in February 2007 and $11 million in common stock dividends in May 2007. We also took steps toward resolving a long-outstanding litigation issue. In January 2007, we reached a preliminary agreement to settle two class action lawsuits related to round-trip trading by CMS MST. We believe that eliminating this business uncertainty is in the best interests of our shareholders.

We are also in the process of restructuring our investment in DIG. This restructuring may involve renegotiation or possible buyout of the DIG power sales contracts as well as other measures. These options may require material cash payments. We believe that resolving the issues associated with the unfavorable supply contracts will allow us to maximize future benefits from our DIG investment.
In the future, we will focus our strategy on:

continued investment in our utility business,
growing earnings while controlling operating costs, and FMLP interests) (187) (58) (129) Corporate Interest

As we execute our strategy, we will need to overcome a sluggish Michigan economy that has been hampered by negative developments in Michigan’s automotive industry and limited growth in the non-automotive sectors of the state’s economy. The return of ROA customer load has offset some of these negative effects. At June 30, 2007, alternative electric suppliers were providing 302 MW of generation service to ROA customers. This is 3 percent of our total distribution load and represents a decrease of 3 percent of ROA load compared to June 30, 2006.

In the first quarter of 2006, we started collecting a surcharge that the MPSC authorized under Section 10d(4) of the Customer Choice Act. Due to timing considerations, thisThis surcharge increased electric delivery revenue by $5$3 million infor the first quarter ofthree months ended June 30, 2007 and $8 million for the six months ended June 30, 2007 versus the same periods in 2006. The increase was primarily due to higher surcharge factors in 2007 versus the same period in 2006.
The Customer Choice Act allows all of our electric customers to buy electric generation service from us or from an alternative electric supplier. At March 31,June 30, 2007, alternative electric suppliers were providing 283302 MW of generation service to ROA customers. This amount represents a decrease of 193 percent compared to March 31,June 30, 2006. The return of former ROA customers to full-service rates increased electric delivery revenue less than $1 million for the three months ended June 30, 2007 and $2 million infor the first quarter ofsix months ended June 30, 2007 versus the same periods in 2006.
Palisades revenue to PSCR:For the three months and six months ended June 30, 2007, as a result of the sale of Palisades, electric revenue of $41 million related to the recovery of the Palisades and Big Rock costs has been used to offset costs incurred under our power purchase agreement with Entergy.

Power supply costs and related revenue:For the three months and six months ended June 30, 2007, PSCR revenue decreased by $12 million versus 2006. OTHER OPERATING EXPENSES, OTHER INCOME AND NON-COMMODITY REVENUE: InThe decrease primarily reflects a reduction in amounts to be recovered under the first quarter ofPSCR mechanism.
Other operating expenses, other income and non-commodity revenue:For the three months ended June 30, 2007, other operating expenses decreased $1$48 million, other income increased $6$10 million, and non-commodity revenue increased $2decreased $3 million versus 2006. For the six months ended June 30, 2007, other operating expenses decreased $49 million, other income increased $16 million, and non-commodity revenue decreased $1 million versus 2006.
The decrease in other operating expenses was primarily due to lower operating and maintenance expense, including reductions to certain workers'workers’ compensation and injuries and damages expense. These decreases were offset partially by higher depreciation amortization, and overheadamortization expense. Operating and maintenance expense decreased primarily due to the absence, in 2007, of costs incurred in 2006 related to a planned refueling outage at our Palisades, nuclear plant, and lower overhead, line maintenance, and storm restoration costs. Also contributing to the decrease was the sale of Palisades in April 2007. Depreciation and amortization expense increased due to higher non-nuclear plant in service and greater amortization of certain regulatory assets. Overhead expense increased primarily due to costs related to our voluntary separation program and costs associated with our utility reorganization. The
For the three months ended June 30, 2007, the increase in other income was primarily due to higher interest income. For the six months ended June 30, 2007, the increase in other income was primarily due to higher interest income and higher income associated with our Section 10d(4) Regulatory Asset. ThisThe increase on our Section 10d(4) Regulatory Asset reflects the absence, in 2007, of the impact of the MPSC'sMPSC’s final order in this case. The increase in non-commodity revenue was primarily due to higher revenue from customer late payment fees. GENERAL TAXES: In
General taxes:For the first quarter ofthree months ended June 30, 2007, general tax expense increased primarily due to higher property tax and sales and use tax expense, offset partially by lower MSBT expense. For the six months ended June 30, 2007, general tax expense versus 2006. INTEREST CHARGES: Inincreased due to higher property tax and sales and use tax expense.
Interest charges:For the first quarter ofthree months and six months ended June 30, 2007, interest charges decreasedincreased primarily due to lower average debt levels and lower interest expense associated with potential customer refundsamounts to be refunded to customers as a result of the sale of Palisades. The MPSC order approving the Palisades power purchase agreement with Entergy directed us to record interest on the unrefunded balance.
Income taxes:For the three months ended June 30, 2007, income taxes increased versus 2006. INCOME TAXES: In2006 primarily due to the first quarterabsence, in 2007, of the resolution of an IRS income tax audit which resulted in an income tax benefit primarily for the utilization or restoration of income tax credits. For the six months ended June 30, 2007, income taxes increased primarily due to higher earnings by the electric utility versus 2006. Partially offsetting this increase is the absence, in 2007, of adjustments to certain deferred tax balances. For additional details, see Note 8, Income Taxes. CMS-7

The increase was primarily due to increased earnings at Jorf Lasfar related to a revised estimate of Jorf Lasfar’s tax reserves during the second quarter 2007, which decreased their tax expense by $11 million.
For the six months ended June 30, 2007 earnings from equity method investees decreased $17 million versus 2006. The decrease iswas primarily the result of lower earnings of $9 million at Jorf Lasfar due to higher income tax expense, a $6 million reductionthe sale of our investments in mark-to-market gains on interest rate swaps associated with our investmentAfrica, the Middle East and India in Taweelah, and a $5 million reduction in earnings at GasAtacama due to higher cost of fuel used for generation as a result of gas shortages. These decreases were partiallyMay 2007, offset by $3 millionthe absence in 2007 of increased earnings at TGN, which was subsequently impaired. GAIN ON SALE OF ASSETS: a 2006 provision for higher foreign taxes in Argentina.
Loss on sale of assets:For the three months ended March 31,June 30, 2007, the net gainloss on asset sales was $12 million.$14 million from the sale of our equity investment in Africa, the Middle East and India to TAQA. This loss was offset by a gain recorded in Income (Loss) from Discontinued Operations, for an overall net gain on the sales transaction. There were no gains or losses on asset sales for the three months ended March 31,June 30, 2006.
For the six months ended June 30, 2007, the net loss on asset sales was $2 million. There were no gains or losses on asset sales for the six months ended June 30, 2006. The net gainloss consisted of a $23 million gainloss on the sale of our equity investmentinvestments in El ChoconAfrica, the Middle East and India to Endesa S.A. partially offset by an $11 millionTAQA, and a loss on the sale of our equity investment in TGM and our Bay Area Pipeline in Michigan to Lucid Energy. These losses were partially offset by a gain on sale of our equity investment in El Chocon to Endesa S.A. For additional details, see Note 2, Asset Sales, Discontinued Operations and Impairment Charges. CMS-9 CMS Energy Corporation OPERATION AND MAINTENANCE:
Operation and maintenance:For the three months ended March 31,June 30, 2007, operation and maintenance expenses decreased $2increased $3 million due to higher professional fees related to the sale of equity investments and higher separation benefits associated with asset sales.
For the six months ended June 30, 2007, operation and maintenance expenses increased $6 million due to the absence of researchhigher professional fees and development costs in 2007 at CMS Energy Brasil S.A. GENERAL TAXES, DEPRECIATION, AND OTHER INCOME, NET: separation benefits associated with the asset sales.
General taxes, depreciation, and other income, net:For the three months ended March 31,June 30, 2007, the net of general tax expense,taxes, depreciation, and other income decreasedincreased operating income compared to 2006 due to higher general taxes recorded in 2006 primarily atrelated to our South American subsidiaries. ASSET IMPAIRMENT CHARGES: holdings.
Asset impairment charges:For the three months ended March 31,June 30, 2007, asset impairment charges were $242$21 million. There were no asset impairment charges for the three months ended March 31,June 30, 2006. The increase was primarily due to the reduction in fair value of our investment in GasAtacama due to the sale agreement entered into June 2007.
For the six months ended June 30, 2007, asset impairment charges were $263 million. There were no asset impairment charges for the six months ended June 30, 2006. The increase was primarily due to the recognition of the reduction in fair value of our investment in TGN, includingwhich included $197 million of cumulative currency translation loss. INCOME TAXES: loss, and the recognition of an additional reduction in the fair value of our investment in GasAtacama.

CMS-13


CMS Energy Corporation
Fixed charges:For the three and six months ended June 30, 2007, fixed charges decreased due to lower interest expenses from subsidiary debt due to asset sales in 2007.
Income taxes:For the three months ended March 31,June 30, 2007, income tax benefit increased $15$14 million versus the same period in 2006. The increase is primarily due to the tax benefits related to asset impairment charges, in 2007, offset partially by the absence, in 2007, of the 2006 resolution of an IRS income tax examination, which resulted in an income tax benefit for the utilization or restoration of income tax credits.
For the six months ended June 30, 2007, income tax benefit increased $35 million versus the same period in 2006. The increase is primarily due to the tax benefit related to asset impairment charges, in 2007, offset by a provision on the cumulative undistributed earnings of foreign subsidiaries expected to be sold during 2007. THEThis was offset partially by the absence, in 2007, of the 2006 resolution of an IRS income tax examination, which resulted in an income tax benefit for the utilization or restoration of income tax credits.
The MCV PARTNERSHIP: Partnership:Due to the November 2006 sale of our ownership interests in the MCV Partnership, we have condensed their consolidated results of operations for the three and six months ended March 31,June 30, 2006 for discussion purposes. The decrease in losses from our ownership interest in the MCV Partnership is primarily due to the absence, in 2007, of mark-to-market losses on certain long-term contracts and financial hedges.

Also contributing to the decrease was the recognition of the reduction in fair value of our investment in GasAtacama and premiums paid on the early retirement of CMS Energy debt in June 2007.
For the six months ended June 30, 2007, net loss from corporate interest and other was $16 million versus net income of $6 million in 2006.

Also contributing to the decrease was the recognition of the reduction in fair value of our international operations during 2007, we determined thatinvestment in GasAtacama and premiums paid on the early retirement of CMS Energy debt in June 2007. Partially offsetting the decrease was the reversal of certain deferred tax valuation allowances associated with capital loss carryforwards and foreign basis differencesin March 2007 that were no longer required. DISCONTINUED OPERATIONS: required due to the sale of our international operations.
Discontinued Operations:For the three months ended March 31,June 30, 2007, net income from discontinued operations was $91 million compared to net income of $12 million in 2006. The increase is primarily due to the gains on the sale of assets which more than offset foreign currency losses, the absence of income related to these businesses, and a $5 million adjustment to tax expense related to previously permanently deferred undistributed foreign earnings.

For the six months ended June 30, 2007, the net loss from discontinued operations was $180$87 million compared to $21 million in net income of $8 million in 2006. The $188$108 million differencechange is primarily due to losses related to the Marchnet loss on the disposal of international businesses in 2007, sale of Argentinewhich replaced earnings recorded for these businesses and non-utility natural gas assets in Michigan. Further contributing to the difference is a reduction in earnings from subsidiaries expected to be sold during the remainder of 2007.

Critical Accounting Policies
The following accounting policies are important to an understanding of our results of operations and financial condition and should be considered an integral part of our MD&A. For additional accounting policies, see Note 1, Corporate Structure and Accounting Policies. USE OF ESTIMATES AND ASSUMPTIONS
Use of Estimates and Assumptions
We use estimates and assumptions in preparing our consolidated financial statements that may affect reported amounts and disclosures. We use accounting estimates for asset valuations, depreciation, amortization, financial and derivative instruments, employee benefits, and contingencies. For example, we estimate the rate of return on plan assets and the cost of future health-care benefits to determine our annual pension and other postretirement benefit costs. Actual results may differ from estimated results due to factors such as changes in the regulatory environment, competition, foreign exchange, regulatory decisions, and lawsuits. CONTINGENCIES:
Contingencies:We are involved in various regulatory and legal proceedings that arise in the ordinary course of our business. We record a liability for contingencies based upon our assessment that a loss is probable and the amount of loss can be reasonably estimated. We use the principles in SFAS No. 5 when recording estimated liabilities for contingencies. We consider many factors in making these assessments, including the history and specifics of each matter.
The amount of income taxes we pay is subject to ongoing audits by federal, state, and foreign tax authorities, which can result in proposed assessments. Our estimate for the potential outcome for any uncertain tax issue is highly judgmental. We believe we have provided adequately for any likely outcome related to these matters. However, our future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period the assessments are made or resolved or when statutes of limitation on potential assessments expire. As a result, our effective tax rate may fluctuate significantly on a quarterly basis. The FASB issued a new interpretation on the recognition and measurement of uncertain tax positions that we adopted on January 1, 2007. For additional details, see the "Implementation“Implementation of New Accounting Standards"Standards” section included in this MD&A. DISCONTINUED OPERATIONS:
Discontinued Operations:We have determined that certain consolidated subsidiaries meet the criteria of assets held for sale under SFAS No. 144. At March 31, 2007, these subsidiaries include Takoradi, SENECA, and certain associated holding companies. At December 31, 2006, these subsidiaries includeincluded our Argentine businesses sold in March 2007, a majority of our Michigan non-utility businesses sold in March 2007, CMS Energy Brasil S.A., Takoradi, SENECA, and certain associated holding companies. There were no assets held for sale at June 30, 2007. For additional details, see Note 2, Asset Sales, Discontinued Operations and Impairment Charges. ACCOUNTING FOR FINANCIAL AND DERIVATIVE INSTRUMENTS, TRADING ACTIVITIES, AND MARKET RISK INFORMATION FINANCIAL INSTRUMENTS:

CMS-15


CMS Energy Corporation
Accounting for Financial and Derivative Instruments, Trading Activities, and Market Risk Information
Financial Instruments:Debt and equity securities classified as available-for-sale are reported at fair value determined from quoted market prices. Debt and equity securities classified as held-to-maturity are reported at cost. Unrealized gains or losses resulting from changes in fair value of certain available-for-sale debt and equity securities are reported, net of tax, in equity as part of AOCL. Unrealized gains or losses are excluded from earnings unless the related changes in fair value are determined to be other than temporary. Unrealized gains or losses on our nuclear decommissioning investments are reflected as regulatory liabilities on our CMS-11 CMS Energy Corporation Consolidated Balance Sheets. Realized gains or losses would not affect our consolidated earnings or cash flows. DERIVATIVE INSTRUMENTS: earnings.
Derivative Instruments:We account for derivative instruments in accordance with SFAS No. 133. Except as noted within this section, since the year ended December 31, 2006, there have been no significant changes in the amount or types of derivatives that we hold or to how we account for derivatives. For additional details on our derivatives, see Note 6, Financial and Derivative Instruments.
To determine the fair value of our derivatives, we use information from external sources (i.e., quoted market prices and third-partythird party valuations), if available. For certain contracts, this information is not available and we use mathematical valuation models to value our derivatives. These models require various inputs and assumptions, including commodity market prices and volatilities, as well as interest rates and contract maturity dates. The following table summarizes the interest rate and volatility rate assumptions we used to value these contracts at March 31,June 30, 2007:
Interest Rates (%)Volatility Rates (%) ------------------ --------------------
Gas-related option contracts 5.00 39 - 49 4.747 – 60
Electricity-related option contracts 5.00 50 - 87 4.764 – 164
Changes in forward prices or volatilities could significantly change the calculated fair value of our derivative contracts. The cash returns we actually realize on these contracts may vary, either positively or negatively, from the results that we estimate using these models. As part of valuing our derivatives at market, we maintain reserves, if necessary, for credit risks arising from the financial condition of our counterparties.
Derivative Contracts Associated with Equity Investments: At March 31,Investments: In May 2007, certainwe sold our ownership interest in businesses in the Middle East, Africa, and India. Certain of our equity method investments, specifically Taweelah, Shuweihat, Jorf Lasfar, and Jubail,these businesses held interest rate contracts and foreign exchange contracts. Wecontracts that were derivatives. Before the sale, we recorded our proportionate share of the change in fair value of these contracts in AOCL if the contracts qualified for cash flow hedge accounting; otherwise, we recorded our share in Earnings from Equity Method Investees. In May 2007, we sold our ownership interest in businesses in
At the Middle East, Africa, and India including Taweelah, Shuweihat, Jorf Lasfar, and Jubail. As a resultdate of the sale, we will no longer recognize gains or losses related to changes in the fair value of the derivative contracts held by these equity method investees. At March 31, 2007, we had accumulated a net loss of $14$13 million, net of tax, in AOCL representing our proportionate share of mark-to-market gains and losses from cash flow hedges held by the equity method investees. At the date we closedAfter the sale, we reclassified this amount adjusted for any additional changes in fair value, was reclassified and recognized it in earnings as parta reduction of the gain on the sale. For additional details on the sale of our interest in these equity method investees, see Note 2, Asset Sales, Discontinued Operations and Impairment Charges.

Consumers maintained trust funds, as required by the NRC, for the purpose of funding certain costs of nuclear plant decommissioning through April 2007, the date of the sale of Palisades. These funds were invested primarily in equity securities, fixed-rate, fixed-income debt securities, and cash and cash equivalents, and have been recorded at fair value on our Consolidated Balance Sheets. These investments were exposed to price fluctuations in equity markets and changes in interest rates. Because the accounting for nuclear plant decommissioning recognized that costs were recovered through Consumers' electric rates, fluctuations in equity prices or interest rates did not affect our consolidated earnings or cash flows.

During the summer months, we purchase natural gas and store it for resale primarily during the winter heating season. Although our prudent natural gas costs are recoverable from our customers, the amount paid for natural gas stored as inventory requires additional liquidity due to the lag in cost recovery. We have credit agreements with our commodity suppliers containing terms that can result in margin calls. While we currently have no outstanding margin calls associated with our natural gas purchases, they may be required if agency ratings are lowered or if market conditions become unfavorable relative to our obligations to those parties.
Our current financial plan includes controlling operating expenses and capital expenditures, executing on asset sales and evaluating market conditions for financing opportunities, if needed.
We believe the following items will be sufficient to meet our liquidity needs: - our current level of cash and revolving credit facilities, - our anticipated cash flows from operating and investing activities, including asset sales, and - our ability to access secured and unsecured borrowing capacity in the capital markets, if necessary.

In additionThe decrease in operating cash flow was a result of the timing of our collection of increased billings in 2007 due to anrecent regulatory actions and weather-driven demand. Also decreasing our operating cash flow was the absence of the return of funds formerly held as collateral under certain gas hedging arrangements and other timing differences. An increase in earnings at our electric and gas utility segments partially reduced these decreases. The absence of payments for higher priced gas made during the increase in operating cash flow was mainly due to the timingfirst part of accounts payable, increased usage of gas inventory in storage, and2006, the absence of the MCV Partnership gas supplier funds on deposit partially offset byand increased usage of gas already in storage during 2007, as the timing of accounts receivable. We experienced colder weather in the first quarter of 2007 versus 2006. The timing of payments for increased natural gas purchases to meet customer demand in the first quarter of 2007, coupled with the absence of payments for higher priced gas made during the first quarter of 2006, increased our operating cash flow. A mildmilder winter in 2006 allowed us to accumulate more gas in our underground storage facilities. The increased usage of gas alreadyfacilities, also offset decreases in storage during the first quarter of 2007 also increased our operating cash flow.

ELECTRIC UTILITY BUSINESS OUTLOOK GROWTH:
Growth:In 2007, we expect electric deliveries to grow about one-half of one percent compared to 2006 levels. The outlook for 2007 assumes a small decline in industrial economic activity and normal weather conditions throughout the remainder of the year.
Over the next five years, we expect electric deliveries to grow at an average rate of about 1.5 percent per year. This outlook assumes a modestly growing customer base and a stabilizing Michigan economy after 2007. This growth rate includes both full-service sales and delivery service to customers who choose to

buy generation service from an alternative electric supplier, but excludes transactions with other wholesale market participants and other electric utilities. This growth rate reflects a long-range expected trend of growth. Growth from year to year may vary from this trend due to customer response to the following: - energy conservation measures, - fluctuations in weather conditions, and - changes in economic conditions, including utilization and expansion or contraction of manufacturing facilities. ELECTRIC CUSTOMER REVENUE OUTLOOK: Our electric utility customer base includes a mix of residential, commercial, and diversified industrial customers. In 2006, Michigan's
energy conservation measures,
fluctuations in weather conditions, and
changes in economic conditions, including utilization and expansion or contraction of manufacturing facilities.
Electric Customer Revenue Outlook:Michigan’s economy has been hampered by automotive industry experienced manufacturing facility closures and restructurings. OurThe Michigan economy has also had limited growth in the non-automotive sector. Although our electric utility results are not dependent upon a single customer, or even a few customers, and customers in the automotive sector represented five percent of our total 2006 electric revenue.
Electric Reserve Margin:We cannot predict the impact of current or possible future restructuring plans or possible future actions by our industrial customers. ELECTRIC RESERVE MARGIN: We are planning forhave a reserve margin of approximately 11 percent for summer 2007, or supply resources equal to 111 percent of projected firm summer peak load. Of the 2007 supply resources target of 111 percent, we expect 96 percent to comecomes from our electric generating plants and long-term power purchase contracts, and 15 percent to comecomes from other contractual arrangements. Our 15-year power purchase agreement with Entergy for 100 percent of the Palisades facility'sfacility’s current electric output will offset the reduction in the owned capacity represented by the sale of the Palisades facility in April 2007. We have purchased capacity and energy contracts covering the reserve margin requirements for 2007 and covering partially the estimated reserve margin requirements for 20072008 through 2010. As a result, we recognized an asset of $62 million for unexpired seasonal capacity and energy contracts at March 31, 2007.
After September 15, 2007, we expect to exercise the regulatory outregulatory-out provision in the MCV PPA, resulting in a reduction in the amount paid to the MCV Partnership to equal the amount we are allowed to recover in the rate charged to customers. If we are successful in exercising this provision, the MCV Partnership may, under certain circumstances, have the right to terminate the MCV PPA, which could affect our reserve margin status. The MCV PPA represents 13 percent of our 2007 supply resources target. ELECTRIC UTILITY PLANT OUTAGE: In September 2006, we removed from service unit three of the J.H. Campbell electric generating plant, representing 765 MW of our capacity. The scheduled outage was for installation of equipment necessary to comply with environmental standards. We expected the unit to return to service in March 2007. However, the outage extended to May 1, 2007 due to unanticipated delays in construction due to labor shortages, the collapse of an outdoor crane on unit three and problems with a major generator component that was refurbished by the original equipment manufacturer. The MPSC allows for the recovery of reasonable and prudent replacement power costs. ELECTRIC TRANSMISSION EXPENSES: resources.
Electric Transmission Expenses:METC, which provides electric transmission service to us, increased CMS-18 CMS Energy Corporation substantially the transmission rates it charged us in 2006. The revenue collected by METC under those rates is subject to refund pending a FERC ruling. In January 2007, the parties filed a settlement agreement with the FERC. This settlement, if approved by the FERC, will result in a refund of 2006 transmission charges of $18 million and a corresponding reduction of our power supply costs. For additional details on power supply costs, see Note 3, Contingencies, "Consumers'“Consumers’ Electric Utility Rate Matters - Power Supply Costs." 21ST CENTURY ELECTRIC ENERGY PLAN:
21st Century Electric Energy Plan:In January 2007, the chairman of the MPSC proposed three major policy initiatives to the governor of Michigan. The initiatives involve the use of more renewable energy resources by all load-serving entities such as Consumers, the creation of an energy efficiency program, and a procedure for reviewing proposals to construct new generation facilities. The January proposal indicated that Michigan needs new base-load capacity by 2015 and recommends measures to make it easier to predict customer demand and revenues. The proposed initiatives will require changes to current legislation. We will continue to participate as the MPSC, legislature, and other stakeholders address future electric resource needs. BALANCED ENERGY INITIATIVE:
Balanced Energy Initiative:In May 2007, we filed a "Balanced“Balanced Energy Initiative"Initiative” with the MPSC providing a comprehensive energy resource plan to meet our projected short-term and long-term electric

CMS Energy Corporation
power requirements. The plan is responsive to the 21st Century Electric Energy Plan and assumes that Michigan will implement a state-wide energy efficiency program and a renewable energy portfolio standard. The filing requests the MPSC to rule that the Balanced Energy Initiative represents a reasonable and prudent plan for the acquisition of necessary electric utility resources.
As acknowledged in the 21st Century Electric Energy Plan, implementation of the Balanced Energy Initiative will require legislative repeal or significant reform of the Michigan customer choice law.Customer Choice Act. In addition, we endorse the 21st Century Electric Energy Plan recommendation to adopt a new, up-front certification policy for major power plant investments. Our filing requests the MPSC to find that the addition of 500 MW of gas-fired combined cycle generating capacity is reasonable and prudent. This addition could be in the form of the construction of a new gas-fired generating plant to begin service in 2011, or in the form of a purchase of an existing gas-fired facility. The filing also recommends construction of a new 750 MW clean coal generating facility on an existing Consumers site to begin operation in 2015. Ownership of 250 MW of the total capacity is assumed to be allocated to municipal entities or other interested parties, resulting in 500 MW dedicated to us. PROPOSED RENEWABLE ENERGY LEGISLATION: our use.
Proposed Power Plant Purchase:In May 2007, we reached an agreement with Broadway Gen Funding LLC, an affiliate of LS Power Group, to buy a 946 MW gas-fired power plant located in Zeeland, Michigan for $517 million. The power plant will help meet the growing energy needs of our customers. We expect to close on the purchase in early 2008, subject to MPSC and other regulatory approvals and other closing conditions.
Proposed Renewable Energy Legislation:There are various bills introduced into in the U.S. Congress and the Michigan legislature relating to mandatory renewable energy standards. If enacted, these bills generally would require electric utilities to acquire a certain percentage of their power from renewable sources or otherwise pay fees or purchase allowances in lieu of having the resources. We cannot predict whether any such bill will be enacted or in what form.
ELECTRIC UTILITY BUSINESS UNCERTAINTIES
Several electric business trends or uncertainties may affect our financial condition and future results of operations. These trends or uncertainties have, or we reasonably expect could have, a material impact on revenues or income from continuing electric operations.
Electric Environmental Estimates:Our operations are subject to environmental laws and regulations. Costs to operate our facilities in compliance with these laws and regulations generally have been recovered in customer rates.
Clean Air Act:Compliance with the federal Clean Air Act and resulting regulations continues to be a significant focus for us. The Nitrogen Oxide State Implementation Plan requires significant reductions in nitrogen oxide emissions. To comply with the regulations, we expect to incur capital expenditures totaling $835 million. These expenditures include installing selective catalytic reduction control technology on CMS-19 CMS Energy Corporation four of our coal-fired electric generating units. The key assumptions in the capital expenditure estimate include: - construction commodity prices, especially construction material and labor, - project completion schedules, - cost escalation factor used to estimate future years' costs, and - an AFUDC capitalization rate. Our current capital cost estimates include an escalation rate of 2.6 percent and an AFUDC capitalization rate of 7.8 percent. From 1998 to present, we have incurred $760$782 million in capital expenditures to comply with the federal Clean Air Act and resulting regulations and anticipate that the remaining $75$53 million of capital expenditures will be made in 2007 through 2011. These expenditures include installing selective catalytic reduction control technology on four of our coal-fired electric generating units. The key assumptions in the capital expenditure estimate include:
construction commodity prices, especially construction material and labor,
project completion schedules,
cost escalation factor used to estimate future years’ costs, and
an AFUDC capitalization rate.

CMS-23


CMS Energy Corporation
Our current capital cost estimates include an escalation rate of 2.6 percent and an AFUDC capitalization rate of 7.8 percent.
In addition to modifying coal-fired electric generating plants, our compliance plan includes the use of nitrogen oxide emission allowances until all of the control equipment is operational in 2011. The nitrogen oxide emission allowance annual expense is projected to be $3$2 million per year, which we expect to recover from our customers through the PSCR process. The projected annual expense is based on market price forecasts and forecasts of regulatory provisions, known as progressive flow control, that restrict the usage in any given year of allowances banked from previous years. The allowances and their cost are accounted for as inventory. The allowance inventory is expensed at the rolling average cost as the electric generating plants emit nitrogen oxide.
Clean Air Interstate Rule:In March 2005, the EPA adopted the Clean Air Interstate Rule that requires additional coal-fired electric generating plant emission controls for nitrogen oxides and sulfur dioxide. We plan to meet the nitrogen oxide requirements of this rule by year-round operation of our selective catalytic reduction control technology units, installation of low nitrogen oxide burners, and purchasing emission allowances. We plan to meet the sulfur dioxide requirements of this rule using sorbent injection, installation of flue gas desulfurization scrubbers and purchasing emission allowances. Our total cost for equipment installation is expected to reach approximately $700 million by 2015. Additional purchases of sulfur dioxide emission allowances in 2012 and 2013 will be needed for an estimated cost of $12 million per year, which we expect to recover from our customers through the PSCR process.
The Clean Air Interstate Rule was appealed to the U.S. Court of Appeals for the District of Columbia by a number of utilities and other companies. Final briefs are due September 5, 2007, with a decision expected in 2008. We cannot predict the outcome of these appeals.
Clean Air Mercury Rule:Also in March 2005, the EPA issued the Clean Air Mercury Rule, which requires initial reductions of mercury emissions from coal-fired electric generating plants by 2010 and further reductions by 2018. The Clean Air Mercury Rule was appealed to the U.S. Court of Appeals by a number of states and other entities. Final briefs were due July 13, 2007, with a decision expected in 2008. We cannot predict the outcome of these appeals.
In April 2006, Michigan'sMichigan’s governor announced a plan that would result in mercury emissions reductions of 90 percent by 2015. We are currently working with the MDEQ on the details of this rule; however, we have developed preliminary cost estimates and a mercury emissions reduction planscenario based on our best knowledge of control technology options and anticipatedinitially proposed requirements. Our plan includes expenditures of approximately $550 million for mercury control equipment and continuous emissions monitoring systems through 2014.

Routine Maintenance Classification:The EPA has alleged that some utilities have incorrectly classified plant modifications as “routine maintenance” rather than seeking permits from the EPA to modify the plant. We have received and responded to information requests from the EPA on this subject. We believe that we have properly interpreted the requirements of “routine maintenance.” If our interpretation is found to be incorrect, we may be required to install additional pollution controls at some or all of our coal-fired electric generating plants and potentially pay fines. Additionally, the viability of certain plants remaining in operation could be called into question.
Greenhouse gases:gases: Several legislative proposals have been introduced in the United States Congress that would require reductions in emissions of greenhouse gases, including carbon dioxide. On April 2, 2007, the U.S. Supreme Court ruled that the Clean Air Act gives the EPA the authority to regulate emissions of carbon dioxide and other greenhouse gases from automobiles. In its decision, the court ordered the EPA to revisit its contention that it has the discretion not to regulate greenhouse gas emissions from automobiles.
To the extent that greenhouse gas emission reduction rules come into effect, the mandatory emissions reduction requirements could have far-reaching and significant implications for the energy sector. We cannot estimate the effect of federal or state greenhouse gas policy on our future consolidated results of operations, cash flows, or financial position due to the uncertain nature of the policies at this time. However, we will continue to monitor greenhouse gas policy developments and assess and respond to their potential implications on our business operations.
Water:In March 2004, the EPA issued rules that govern electric generating plant cooling water intake systems. The rules require significant reduction in fish killed by operating equipment. EPA compliance options in the rule were challenged in court. In January 2007, the court rejected many of the compliance options favored by industry and remanded the bulk of the rule back to the EPA for reconsideration. The court'scourt’s ruling is expected to increase significantly the cost of complying with this rule. However, the cost to comply will not be known until the EPA'sEPA’s reconsideration is complete. At this time, the EPA has not established a schedule to address the court decision.

Competition and Regulatory Restructuring:The Customer Choice Act allows all of our electric customers to buy electric generation service from us or from an alternative electric supplier. At March 31,June 30, 2007, alternative electric suppliers were providing 283302 MW of generation service to ROA customers.

If downward ROA trends continue, it maywill extend the time it takes to recover fully our Stranded Costs. It is difficult to predict future ROA customer trends, which affect our ability to recover timely ourthese Stranded Costs. CMS-21 CMS Energy Corporation ELECTRIC RATE CASE:
Electric Rate Case:In March 2007, we filed an application with the MPSC seeking an 11.25 percent authorized return on equity and an annual increase in revenues of $157 million. The increase includesseeks recovery of the costs associated with increased plant investment, increased equity investment, and greater operation and maintenance expenses. In May 2007, we filed supplemental testimony with the MPSC to include transaction costs from the sale of Palisades. In July 2007, we filed an amended application with the MPSC to include the proposed purchase of the Zeeland power plant, the approval of an energy efficiency program, and to make other revisions. The revised application seeks an annual increase in revenues of $282 million.
In July 2007, we also filed a $23 million basemotion for partial and immediate rate reduction,relief that seeks the additionremoval of costs associated with Palisades, the approval of partial and immediate rate relief for certain items, including the proposed purchase of the Zeeland power plant, and the approval of a $13plan to distribute $127 million surchargeof excess proceeds from the sale of Palisades to customers.

OTHER ELECTRIC UTILITY BUSINESS UNCERTAINTIES THE
The MCV PARTNERSHIP: Partnership:The MCV Partnership, which leases and operates the MCV Facility, contracted to sell electricity to Consumers for a 35-year period beginning in 1990.
Underrecoveries related to the MCV PPA:The cost that we incur under the MCV PPA exceeds the recovery amount allowed by the MPSC. As a result, we estimate cash underrecoveries of capacity and fixed energy payments of $39 million in 2007. However, we use the direct savings from the RCP, after allocating a portion to customers, to offset a portion of our capacity and fixed energy underrecoveries expense. After September 15, 2007, we expect to claim relief under the regulatory outregulatory-out provision in the MCV PPA, thereby limiting our capacity and fixed energy payments to the MCV Partnership to the amounts that we collect from our customers. This action would eliminate our underrecoveries of capacity and fixed energy payments.
The MCV Partnership has notified us that it takes issue withopposes our intended exercise of the regulatory outregulatory-out provision after September 15, 2007. We believe that the provision is valid and fully effective, but cannot assure that itwe will prevail in the event of a dispute. If we are successful in exercising the regulatory outregulatory-out provision, the MCV Partnership may, under certain circumstances, have the right to terminate or reduce the amount of capacity sold under the MCV PPA. If the MCV Partnership terminates the MCV PPA or reduces the amount of capacity sold under the MCV PPA, we would seek to replace the lost capacity to maintain an

adequate electric reserve margin. This could involve entering into a new PPA and (or) entering into electric capacity contracts on the open market. We cannot predict our ability to enter into such contracts at a reasonable price. We are also unable to predict regulatory approval of the terms and conditions of such contracts, or that the MPSC would allow full recovery of our incurred costs.
To comply with a prior MPSC order, we made a filing in May 2007 with the MPSC, which asked the MPSC to make a determination regarding whether it wished to reconsider the amount of the MCV PPA payments that we recover from customers. Also, in May 2007, the MCV Partnership filed an application with the MPSC seeking approval to increase our recovery of costs incurred under the MCV PPA.

GAS UTILITY BUSINESS OUTLOOK GROWTH:
Growth:In 2007, we project gas deliveries will decline slightly, on a weather-adjusted basis, from 2006 levels due to continuing conservation and overall economic conditions in the state of Michigan. Over the next five years, we expect gas deliveries to decline by less than one-half of one percent annually. Actual gas deliveries in future periods may be affected by: - fluctuations in weather conditions, - use by independent power producers, - competition in sales and delivery, - changes in gas commodity prices, - Michigan economic conditions, - the price of competing energy sources or fuels, - gas consumption per customer, - improvements in gas appliance efficiency, and - use of a Revenue Decoupling and Conservation Incentive mechanism.

ENTERPRISES OUTLOOK
Our primary focus with respect to our non-utility businesses is to optimize cash flow and further reduce our business risk and leverage through the sale of non-strategic assets. In 2007, we intend to complete the sale of several Enterprises assets, including all of our businesses in Latin America, the Middle East, North Africa and India. In February 2007, we entered into an Agreement of Purchase and Sale with TAQA to sell our ownership interest in businesses in the Middle East, Africa, and India for $900 million. Businesses included in the sale are Taweelah, Shuweihat, Jorf Lasfar, Jubail, Neyveli, and Takoradi and are subject to the receipt of all necessary governmental, lender and partner approvals.
We closed on the sale in May 2007. After considering the effects of taxes, post-closing adjustments, and closing costs, we anticipate a gain of approximately $50 million. The estimated gain is also subject to a number of adjustments that will occur at or shortly after closing. In March 2007, we completed the sale of a portfolio of our businesses in Argentina and our northern Michigan non-utility natural gas assets to Lucid Energy for $130 million. million in March 2007.
In connection with the sale of our Argentine and Michigan assets, we entered into agreements that grant Lucid Energy:
an option to buy CMS Gas Transmission’s ownership interest in TGN, subject to the rights of other third parties,
the right to a portion of proceeds that may be awarded and received by CMS Gas Transmission in connection with certain legal proceedings, and
the right to all of the proceeds that Enterprises will receive if it sells its stock interest in CMS Generation San Nicolas Company.
Under these agreements, we have essentially sold our rights to certain awards or proceeds that we may receive in the future. A portion of the consideration received in the sale has been allocated to these agreements. We have recorded $32 million as a deferred credit in Other Non-current Liabilities on our Consolidated Balance Sheets.
We also sold our interest in El Chocon, an Argentine hydroelectric generating business, to Endesa, S.A. for $50 million. Ourmillion in March 2007.
We sold our ownership interest in El Chocon was originally part of the asset group that Lucid Energy agreedSENECA and certain associated generating equipment to purchase; however, Endesa, S.A. had a right of first offer on our interest in El Chocon that it exercised. We will maintain our interest in the TGN natural gas business in Argentina, which remains subject to a potential sale to the government of Argentina or some other disposition. In recognition of our commitment to sell our 23.5 percent interest in TGN, in the first quarter of 2007 we recorded an after-tax impairment charge of $140 million, which consisted of a reduction in the fair value of our TGN ownership interest of $12 million, net of tax, and recognition of cumulative foreign currency translation losses of $128 million, net of tax. In April 2007, we entered into a purchase and sale agreement with Petroleos de Venezuela, S.A., which is owned by the Bolivarian Republic of Venezuela, to sell our ownership interest in SENECA and certain associated generating equipment for gross cash proceeds of $106 million. We closed on the salemillion in April 2007. In April 2007, we entered into an agreement to sell CMS Energy Brasil S.A. for $211 million to CPFL Energia S.A., a Brazilian utility.
We expect to close on the sale by the end of the second quarter of 2007, subject to approval by the Brazilian national regulatory agency.

For additional details, see Note 2, Asset Sales, Discontinued Operations and Impairment Charges. UNCERTAINTIES:
Uncertainties:Trends or uncertainties that could have a material impact on our consolidated income, cash flows, or balance sheet and credit improvement include: - successful close of the sale of CMS Energy Brasil S.A., - the outcome of the planned sale of other generation and distribution assets, including the following uncertainties which could affect the value of certain of these businesses: - changes in available gas supplies or Argentine government regulations that could further restrict natural gas exports to our GasAtacama electric generating plant, - changes in exchange rates or in local economic or political conditions, and - changes in foreign taxes or laws or in governmental or regulatory policies that could reduce significantly the tariffs charged and revenues recognized by certain foreign subsidiaries, or increase expenses, - impact of indemnity and environmental remediation obligations at Bay Harbor, - changes in commodity prices and interest rates on certain derivative contracts that do not qualify for hedge accounting and must be marked to market through earnings, and - impact of representations, warranties, and related indemnities in connection with the sales of SENECA, Argentine assets to Lucid Energy, CMS Energy Brasil S.A., and other pending sales if completed and closed. GASATACAMA: At March 31, 2007, the carrying value of our investment in GasAtacama was $114 million. This remaining value continues to be exposed to the threat of a complete gas restriction by Argentina and the inability of GasAtacama to pass through the increased costs associated with such a restriction to its regulated customers. Therefore, if conditions do not improve, the result could be a further impairment of our investment in GasAtacama. In February 2007, we announced plans to conduct an auction to sell GasAtacama. We expect to complete the sale by the end of 2007. For additional details, see Note 2, Asset Sales, Discontinued Operations and Impairment Charges. CMS-25 CMS Energy Corporation PRAIRIE STATE:

Prairie State:In October 2006, we signed agreements with Peabody Energy to co-develop the Prairie State Energy Campus (Prairie State), a 1,600 MW power plant and coal mine in southern Illinois. In April 2007, we withdrew from Prairie State because at this time, it doesdid not meet our investment criteria, including the level of power purchase agreements for our share of output from Prairie State. OTHER OUTLOOK RULES REGARDING BILLING PRACTICES: In December 2006, the MPSC issued proposed rule changes to residential customer billing standards
Other Outlook
Litigation and practices. These changes, if adopted, would provide additional protection to low-income customers during the winter heating season that will be defined as November 1 through March 31, extend the time between billing date and due date from 17 days to 22 days, and eliminate estimated metering readings unless actual readings are not feasible. We are presently evaluating the impacts of these proposed rules and are working with other Michigan utilities in providing comments to the MPSC regarding the proposed rule changes. LITIGATION AND REGULATORY INVESTIGATION: Regulatory Investigation:We are the subject of an investigation by the DOJ regarding round-trip trading transactions by CMS MST. Also, we are named as a party in various litigation matters including, but not limited to, securities class action lawsuits and several lawsuits regarding alleged false natural gas price reporting and price manipulation. Additionally, the SEC is investigating the actions of former CMS Energy subsidiaries in relation to Equatorial Guinea. For additional details regarding these and other matters, see Note 3, Contingencies and Part II, Item 1. Legal Proceedings. FIXED PRICE CONTRACTS:
Fixed Price Contracts:DIG and CMS ERM are parties to long-term requirements contracts to provide steam and/orand (or) electricity based on a fixed price schedule. The price of natural gas, the primary fuel used by DIG, is volatile and has increased substantially in recent years. Because the prices charged under DIG'sDIG’s contracts do not reflect current natural gas prices, DIG'sDIG’s and CMS ERM'sERM’s financial performance has been impacted negatively. However, since not all of its capacity is committed under these contracts, DIG has been able to sell a portion of its electric capacity and (or) energy on the market at a profit, or, through CMS ERM, engage in a hedging strategy to minimize its losses. DIG and CMS ERM may take various actions such as seeking restructuring or buyout of the contracts.contracts, which may require material cash payments. CMS Energy may also take other measures to address the unfavorable returns. PENSION REFORM:
Michigan Business Tax Act:In August 2006,July 2007, the PresidentMichigan governor signed into lawSenate Bill 94, the Pension ProtectionMichigan Business Tax Act, which imposes a business income tax of 2006.4.95 percent and a modified gross receipts tax of 0.8 percent. The bill reformsprovides for a number of tax credits and incentives, geared towards those companies investing and employing in Michigan. The Michigan Business Tax, which is effective January 1, 2008, replaces the funding rulesstate’s current Single Business Tax that expires on December 31, 2007. We are currently evaluating the impact this new tax will have on us. We do not expect an increase to our State tax

liability. Absent any State legislative or regulatory action, however, we may need to record a material non-cash deferred tax charge for employer-provided pension plans, effectivethis new tax.
Implementation of New Accounting Standards
SFAS No. 158, Employers’ Accounting for plan years beginning after 2007. As a resultDefined Benefit Pension and Other Postretirement Plans - - an amendment of this bill, we expect to reduce our contributions to the Pension Plan over the next 10 years by a present value amount of $56 million. IMPLEMENTATION OF NEW ACCOUNTING STANDARDS SFAS NO. 158, EMPLOYERS' ACCOUNTING FOR DEFINED BENEFIT PENSION AND OTHER POSTRETIREMENT PLANS - AN AMENDMENT OF FASB STATEMENTS NO.Statements No. 87, 88, 106, ANDand 132(R):In September 2006, the FASB issued SFAS No. 158. Phase one of this standard required us to recognize the funded status of our defined benefit postretirement plans on our Consolidated Balance Sheets at December 31, 2006. Phase one was implemented in December 2006. Phase two of this standard requires that we change our plan measurement date from November 30 to December 31, effective December 31, 2008. We do not believe that implementation of phase two of this standard will have a material effect on our consolidated financial statements. We expect to adopt the measurement date provisions of SFAS No. 158 in 2008.
FIN 48, ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES: Accounting for Uncertainty in Income Taxes:We adopted the provisions of FIN 48 on January 1, 2007. This interpretation provides a two-step approach for the recognition and measurement of CMS-26 CMS Energy Corporation uncertain tax positions taken, or expected to be taken, by a company on its income tax returns. The first step is to evaluate the tax position to determine if, based on management'smanagement’s best judgment, it is greater than 50 percent likely that we will sustain the tax position. The second step is to measure the appropriate amount of the benefit to recognize. This is done by estimating the potential outcomes and recognizing the greatest amount that has a cumulative probability of at least 50 percent. FIN 48 requires interest and penalties, if applicable, to be accrued on differences between tax positions recognized in our consolidated financial statements and the amount claimed, or expected to be claimed, on the tax return.
As a result of the implementation of FIN 48, we have identified additional uncertain tax benefits of $11 million as of January 1, 2007. Included in this amount is an increase in our valuation allowance of $100 million, decreases to tax reserves of $61 million and a decrease to deferred tax liabilities of $28 million. In addition, our equity method investment, Jorf Lasfar, in which we held a 50 percent interest, identified $26 million of uncertain tax benefits in its adoption of FIN 48 for U.S. GAAP purposes. We have reflected our share of this amount, $13 million, as a reduction to our beginning retained earnings balance and in our investment in the subsidiary. Thus, our beginning retained earnings was reduced by $24 million as a result of the adoption of FIN 48.
CMS Energy and its subsidiaries file a consolidated U.S. federal income tax return as well as unitary and combined income tax returns in several states. CMS Energy and its subsidiaries also file separate company income tax returns in several states. The only significant state tax paid by CMS Energy is in Michigan. However, since the Michigan Single Business Tax is not an income tax, it is not part of the FIN 48 analysis. For the U.S. federal income tax return, CMS Energy completed examinations by federal taxing authorities for its taxable years prior to 2002. The federal income tax returns for the years 2002 through 2005 are open under the statute of limitations.
We have reflected a net interest liability of $3 million related to our uncertain income tax positions on our Consolidated Balance Sheets as of January 1, 2007. We have not accrued any penalties with respect to uncertain tax benefits. We recognize accrued interest and penalties, where applicable, related to uncertain tax benefits as part of income tax expense.
As of the date of adoption of FIN 48, we had valuation allowances against certain U.S. and foreign deferred tax assets totaling $216 million and other uncertain tax positions of $31 million, resulting in total unrecognized benefits of $247 million. Of this amount, $217 million would result in a decrease in our effective tax rate, if recognized. We released $81 million of our valuation allowance in the first quarter of 2007, reducing our effective tax rate, due to the anticipated sales of our foreign investments,investments. During the second quarter of 2007, we reversed $63 million of valuation allowance attributable to additional foreign asset sales. This reversal had no income impact, as reflected in our effectivean identical amount of deferred tax rate reconciliation in Note 8, Income Taxes. Therefore, remaining uncertain tax benefits that would reduce our effective tax rate beyond this quarter are $136 million.asset was also

reversed. As we continue to market our foreign investments, it is reasonably possible that additional valuation allowance adjustments could be made. We are not in a position to estimate any additional adjustment at this date, other than to state that we have no expectation of reversing any of the $86 million valuation allowance attributable to the inflation indexing of our Venezuelan investment. We are not expecting any other material changes to our uncertain tax positions. NEW ACCOUNTING STANDARDS NOT YET EFFECTIVE
New Accounting Standards Not Yet Effective
SFAS NO.No. 157, FAIR VALUE MEASUREMENTS: Fair Value Measurements:In September 2006, the FASB issued SFAS No. 157, effective for us January 1, 2008. The standard provides a revised definition of "fair value"“fair value” and gives guidance on how to measure the fair value of assets and liabilities. Under the standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly exchange between market participants. The standard does not expand the use of fair value in any new circumstances. However, additional disclosures will be required on the impact and reliability of fair value measurements reflected in CMS-27 CMS Energy Corporation our consolidated financial statements. The standard will also eliminate the existing prohibition of recognizing "day one"“day one” gains or losses on derivative instruments, and will generally require such gains and losses to be recognized through earnings. We are presently evaluating the impacts, if any, of implementing SFAS No. 157. We currently do not hold any derivatives that would involve day one gains or losses.
SFAS NO.No. 159, THE FAIR VALUE OPTION FOR FINANCIAL ASSETS AND FINANCIAL LIABILITIES, INCLUDING AN AMENDMENT TOThe Fair Value Option for Financial Assets and Financial Liabilities, Including an amendment to FASB STATEMENT NO.Statement No. 115:In February 2007, the FASB issued SFAS No. 159, effective for us January 1, 2008. This standard will give us the option to select certain financial instruments and other items, which otherwise are not required to be measured at fair value, and measure those items at fair value. If we choose to elect the fair value option for an item, we would recognize unrealized gains and losses associated with changes in the fair value of the item over time. The statement will also require disclosures for items for which the fair value option has been elected. We are presently evaluating whether we will choose to elect the fair value option for any financial instruments or other items. CMS-28
FSP FIN 39-1,Amendment of FASB Interpretation No. 39:In April 2007, the FASB issued FSP FIN 39-1, effective for us January 1, 2008. This standard will permit us to offset the fair value of derivative instruments with cash collateral received or paid for those derivative instruments executed with the same counterparty under a master netting arrangement. As a result, we will be permitted to record one net asset or liability that represents the total net exposure of all derivative positions under a master netting arrangement. The decision to offset derivative positions under master netting arrangements remains an accounting policy choice. We presently record the net fair value of derivative assets and liabilities for those contracts held by CMS ENERGY CORPORATION CONSOLIDATED STATEMENTS OF INCOME (LOSS) (UNAUDITED)

Notes to Consolidated Financial Statements
(Unaudited)
These interim Consolidated Financial Statements have been prepared by CMS Energy in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. As such, certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. Certain prior year amounts have been reclassified to conform to the presentation in the current year, including certain reclassifications to our Consolidated Financial Statements for discontinued operations. Therefore, the consolidated financial statements for the year ended December 31, 2006 and for the three and six months ended June 30, 2006 have been updated for amounts previously reported. In management'smanagement’s opinion, the unaudited information contained in this report reflects all adjustments of a normal recurring nature necessary to assure the fair presentation of financial position, results of operations and cash flows for the periods presented. The Notes to Consolidated Financial Statements and the related Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related Notes contained in CMS Energy'sEnergy’s Form 10-K for the year ended December 31, 2006.2006 and the Form 8-K filed June 4, 2007 amending CMS Energy’s 2006 financial statements to reflect certain discontinued operations resulting from certain asset sales. Due to the seasonal nature of CMS Energy'sEnergy’s operations, the results as presented for this interim period are not necessarily indicative of results to be achieved for the fiscal year.
1: CORPORATE STRUCTURE AND ACCOUNTING POLICIES CORPORATE STRUCTURE: Corporate Structure and Accounting Policies
Corporate Structure:CMS Energy is an energy company operating primarily in Michigan. We are the parent holding company of Consumers and Enterprises. Consumers is a combination electric and gas utility company serving Michigan'sMichigan’s Lower Peninsula. Enterprises, through various subsidiaries and equity investments, is engaged in primarily domestic and international diversified energy businesses including independent power production, electric distribution, and natural gas transmission, storage and processing.production. We manage our businesses by the nature of services each provides and operate principally in three business segments: electric utility, gas utility, and enterprises. PRINCIPLES OF CONSOLIDATION:
Principles of Consolidation:The consolidated financial statements include CMS Energy, Consumers, Enterprises, and all other entities in which we have a controlling financial interest or are the primary beneficiary, in accordance with FIN 46(R). We use the equity method of accounting for investments in companies and partnerships that are not consolidated, where we have significant influence over operations and financial policies, but are not the primary beneficiary. We eliminate intercompany transactions and balances. USE OF ESTIMATES:
Use of Estimates:We prepare our consolidated financial statements in conformity with U.S. GAAP. We are required to make estimates using assumptions that may affect the reported amounts and disclosures. Actual results could differ from those estimates.
We record estimated liabilities for contingencies in our consolidated financial statements when it is probable that a loss will be incurred in the future as a result of a current event, and when an amount can be reasonably estimated. For additional details, see Note 3, Contingencies. REVENUE RECOGNITION POLICY:
Revenue Recognition Policy:We recognize revenues from deliveries of electricity and natural gas, CMS-37 CMS Energy Corporation and the transportation, processing, and storage of natural gas when services are provided. We record

CMS-39


CMS Energy Corporation
sales tax on a net basis and exclude it from revenues. We recognize revenues on sales of marketed electricity, natural gas, and other energy products at delivery. We recognize mark-to-market changes in the fair values of energy trading contracts that qualify as derivatives as revenues in the periods in which the changes occur. INTERNATIONAL OPERATIONS AND FOREIGN CURRENCY:
International Operations and Foreign Currency:Our subsidiaries and affiliates whose functional currency is not the U.S. dollar translate their assets and liabilities into U.S. dollars at the exchange rates in effect at the end of the fiscal period. We translate revenue and expense accounts of such subsidiaries and affiliates into U.S. dollars at the average exchange rates that prevailed during the period. We show these foreign currency translation adjustments in the stockholders'stockholders’ equity section on our Consolidated Balance Sheets. We include exchange rate fluctuations on transactions denominated in a currency other than the functional currency, except those that are hedged, in determining net income.
At March 31,June 30, 2007, the cumulative Foreign Currency Translation component of stockholders'stockholders’ equity was $169$129 million, net of tax, which primarily represents currency losses in Argentina and Brazil.Argentina. The cumulative foreign currency loss due to the unfavorable exchange rate of the Argentine peso using an exchange rate of 3.1023.089 pesos per U.S. dollar was $129 million, net of tax. The cumulative foreign currency loss due to the unfavorable exchange rate
Impairment of the Brazilian real using an exchange rate of 2.04 reais per U.S. dollar was $41 million, net of tax. IMPAIRMENT OF LONG-LIVED ASSETS AND EQUITY METHOD INVESTMENTS: Long-Lived Assets and Equity Method Investments:We evaluate potential impairments of our long-lived assets, other than goodwill, based on various analyses, including the projection of undiscounted cash flows, whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the carrying amount of the investment or asset exceeds its estimated undiscounted future cash flows, we recognize an impairment loss and write-down the investment or asset to its estimated fair value.
We also assess our ability to recover the carrying amounts of our equity method investments whenever events or changes in circumstances indicate that the carrying amount of the investments may not be recoverable. This assessment requires us to determine the fair values of our equity method investments. We determine fair value using valuation methodologies, including discounted cash flows and the ability of the investee to sustain an earnings capacity that justifies the carrying amount of the investment. We record a write down if the fair value is less than the carrying value and the decline in value is considered to be other than temporary.

Reclassifications:We have reclassified certain prior year amounts for comparative purposes. These reclassifications did not affect consolidated net income (loss) for the periods presented. The most significant of these reclassifications is related to certain subsidiaries reclassified as "held“held for sale"sale” on our Consolidated Balance Sheets and activities of those subsidiaries as Income (Loss) From Discontinued Operations in our Consolidated Statements of Income (Loss). For additional details, see Note 2, Asset Sales, Discontinued Operations and Impairment Charges, "Discontinued“Discontinued Operations." CMS-38 CMS Energy Corporation NEW ACCOUNTING STANDARDS NOT YET EFFECTIVE:
New Accounting Standards Not Yet Effective:SFAS No. 157, Fair Value Measurements: Measurements:In September 2006, the FASB issued SFAS No. 157, effective for us January 1, 2008. The standard provides a revised definition of "fair value"“fair value” and gives guidance on how to measure the fair value of assets and liabilities. Under the standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly exchange between market participants. The standard does not expand the use of fair value in any new circumstances. However, additional disclosures will be required on the impact and reliability of fair value measurements reflected in our consolidated financial statements. The standard will also eliminate the existing prohibition of recognizing "day one"“day one” gains or losses on derivative instruments, and will generally require such gains and losses to be recognized through earnings. We are presently evaluating the impacts, if any, of implementing SFAS No. 157. We currently do not hold any derivatives that would involve day one gains or losses.
SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, Including an amendment to FASB Statement No. 115: 115:In February 2007, the FASB issued SFAS No. 159, effective

CMS-41


CMS Energy Corporation
for us January 1, 2008. This standard will give us the option to select certain financial instruments and other items, which otherwise are not required to be measured at fair value, and measure those items at fair value. If we choose to elect the fair value option for an item, we would recognize unrealized gains and losses associated with changes in the fair value of the item over time. The statement will also require disclosures for items for which the fair value option has been elected. We are presently evaluating whether we will choose to elect the fair value option for any financial instruments or other items. 2: ASSET SALES, DISCONTINUED OPERATIONS AND IMPAIRMENT CHARGES ASSET SALES
FSP FIN 39-1,Amendment of FASB Interpretation No. 39: In MarchApril 2007, the FASB issued FSP FIN 39-1, effective for us January 1, 2008. This standard will permit us to offset the fair value of derivative instruments with cash collateral received or paid for those derivative instruments executed with the same counterparty under a master netting arrangement. As a result, we will be permitted to record one net asset or liability that represents the total net exposure of all derivative positions under a master netting arrangement. The decision to offset derivative positions under master netting arrangements remains an accounting policy choice. We presently record the net fair value of derivative assets and liabilities for those contracts held by CMS ERM that are subject to master netting arrangements, and separately record amounts for cash collateral received or paid for these instruments. Under this standard, as a result of offsetting the collateral amounts against the fair value of derivative assets and liabilities, both our total assets and total liabilities could be reduced. The standard is to be applied retrospectively by adjusting the financial statements for all periods presented. There will be no impact to earnings from adopting this standard.
EITF Issue 06-11, Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards:In June 2007, the FASB ratified EITF Issue 06-11, effective for us on a prospective basis beginning January 1, 2008. EITF 06-11 requires companies to recognize the income tax benefit realized from dividends or dividend equivalents that are charged to retained earnings and paid to employees for non-vested equity-classified employee share-based payment awards as an increase to additional paid-in capital. We do not believe that implementation of this standard would have a material effect on our financial statements.
2:Asset Sales, Discontinued Operations and Impairment Charges
Asset Sales
The impacts of our asset sales are included in Loss on asset sales, net and Income (Loss) from Discontinued Operations in our Consolidated Statements of Income (Loss). There were no asset sales for the six months ended June 30, 2006.
We completed the sale of a portfolio of our businesses in Argentina and our northern Michigan non-utility natural gas assets to Lucid Energy for gross cash proceeds of $130 million.million in March 2007. The Argentine assets sold include our electric generating plant interests$301 million pretax loss on sale includes a $279 million loss in Argentinadiscontinued operations and our interesta $22 million loss in the TGM natural gas transportation and pipeline business in Argentina. The Michigan assets sold include the Antrim natural gas processing plant, 155 miles of associated gathering lines, and interests in three special purpose gas transmission pipelines that total 110 miles. continuing operations.
In connection with the sale of our Argentine and Michigan assets, we entered into agreements that grant Lucid Energy: - -
an option to buy CMS Gas Transmission’s ownership interest in TGN, subject to the rights of other third parties,
the right to a portion of proceeds that may be awarded and received by CMS Gas Transmission in connection with certain legal proceedings, and

CMS Gas Transmission's ownership interest in TGN, subject to the rights of other third parties, - - the right to a portion of damages that may be awarded and received by CMS Gas Transmission in connection with certain legal proceedings, and - - Energy Corporation
the right to all of the proceeds that Enterprises will receive if it sells its stock interest in CMS Generation San Nicolas Company.
Under these agreements, we have essentially sold our rights to certain awards or proceeds that we may receive in the future. A portion of the consideration received in the sale has been allocated to these agreements. We have recorded $32 million as a deferred credit in Other Non-current Liabilities on our Consolidated Balance Sheets. In March 2007, we

We sold our ownership interest in SENECA and certain associated generating equipment to Petroleos de Venezuela, S.A., which is owned by the Bolivarian Republic of Venezuela, for gross cash proceeds of $106 million in April 2007. We recorded a $46 million pretax gain in discontinued operations.
We sold our asset sales areownership interest in businesses in the Middle East, Africa, and India to TAQA for $900 million in May 2007. Gross proceeds from the sale included $792 million in cash proceeds and TAQA’s assumption of $108 million in debt. Businesses included in Gainthe sale were Takoradi, Taweelah, Shuweihat, Jorf Lasfar, Jubail, and Neyveli. The $80 million pretax gain on asset sales, netsale includes a $96 million gain recorded in discontinued operations and Income (Loss) from Discontinued Operationsa $16 million loss recorded in our Consolidated Statements of Income (Loss). There were no asset sales for the three months ended March 31, 2006. For the three months ended March 31,continuing operations.
In June 2007, we sold CMS Energy Brasil S.A. to CPFL Energia S.A., a Brazilian utility, for $211 million, which included $201 million in cash proceeds and CPFL Energia S.A.’s assumption of a $10 million tax liability. We recorded a $3 million pretax gain in discontinued operations.

Sale of Purchase and Sale with TAQA to sell our ownership interest in businesses in the Middle East, Africa, and India for $900 million. Businesses included in the sale are Taweelah, Shuweihat, Jorf Lasfar, Jubail, Neyveli, and Takoradi. We closed on the sale in May 2007. The book value of these assets at March 31, 2007 was approximately $682 million. After considering the effects of taxes, post-closing adjustments, and closing costs, we anticipate a gain of approximately $50 million. The estimated gain is also subject to a number of adjustments that will occur at or shortly after closing. Nuclear Assets:In April 2007, we sold Palisades to Entergy for $380 million. The final purchase price wasis subject to various closing adjustments resulting in us receiving $361 million.such as working capital and capital expenditure adjustments and nuclear fuel usage and inventory adjustments. We have received $364 million as of June 2007; however, certain purchase price adjustments are not yet final. We also paid Entergy $30 million to assume ownership and responsibility for the Big Rock ISFSI. We entered into a 15-year power purchase agreement with Entergy for 100 percentBecause of the plant's current electric output. For additional details on sale of Palisades, we paid the NMC, the former operator of Palisades, $7 million in exit fees and forfeited our $5 million investment in the NMC.
Entergy assumed responsibility for the future decommissioning of Palisades and for storage and disposal of spent nuclear fuel located at Palisades and the Big Rock ISFSI seesites. At closing, we transferred $252 million

in decommissioning trust fund balances to Entergy. We are refunding estimated excess decommissioning funds of $189 million to our retail customers through credits applied from June 2007 through December 2008 and have recorded this obligation as a regulatory liability on our Consolidated Balance Sheets. Modification to the terms of the transaction allowed us immediate access to additional excess decommissioning trust funds of $122 million. We have proposed a plan to refund these excess decommissioning fund balances through credits to our retail customers’ bills. This plan is under review by the MPSC in our current electric rate case filing. We recorded this balance as a regulatory liability on our Consolidated Balance Sheets.
The MPSC order approving the Palisades transaction allows us to recover the book value of Palisades, which we estimated at $314 million. As a result, we are refunding proceeds in excess of book value of $66 million to our retail customers through credits applied from June 2007 through December 2008. The final proceeds in excess of the book value are subject to closing adjustments and review by the MPSC. The MPSC order deferred ruling on the recovery of transaction costs, including the NMC exit fees, and the $30 million payment to Entergy related to the Big Rock ISFSI until our next general rate case. We deferred these costs as a regulatory asset on our Consolidated Balance Sheets as recovery is probable.
In April 2007, the NRC issued an order approving the transfer of the Palisades operating license. Intervenors have filed petitions for reconsideration of the NRC orders approving the transfer of the Palisades and Big Rock licenses. The NRC did not alter or stay the prior order approving the license transfer. We believe that it is unlikely that the NRC will conduct further proceedings or alter its prior orders, but we cannot predict the outcome of the matter.

(b)As of June 30, 2007, we have $56 million recorded as a regulatory asset for Palisades deferred costs of which $26 million relates to transaction costs. We estimate that we will incur an additional $2 million in selling expenses related to the Palisades transaction.
In the FERC’s February 2007 order regarding the Palisades transaction, the FERC granted our request to apply $11 million in FERC decommissioning trust fund balances for Palisades toward the Big Rock decommissioning shortfall, as described in Note 3, Contingencies, "Other Consumers'“Other Consumers’ Electric Utility Contingencies -–Nuclear Matters.” The Saleorder was contingent upon the NRC approving the transfer of Nuclear Assetsoperating licenses, which the NRC approved in April 2007. A clarification request was filed by a wholesale customer with the FERC. In July 2007, the FERC issued a clarification order requiring us to demonstrate that the fund did not have a surplus balance and the if any surplus exists that we submit a refund plan.
Palisades Power Purchase Agreement." InAgreement:Entergy contracted to sell us 100 percent of the plant’s output up to its current annual average capacity of 798 MW under a 15-year power purchase agreement beginning in April 2007. We provided $30 million in security to Entergy for our power purchase agreement obligation in the form of a letter of credit. We estimate that capacity and energy payments under the Palisades power purchase agreement will be $180 million in 2007 and average $300 million per year thereafter.
Due to the Palisades power purchase agreement, the transaction is a sale and leaseback for accounting purposes. SFAS No. 98 specifies the accounting required for a seller’s sale and simultaneous leaseback involving real estate. We have continuing involvement with Palisades through security provided to Entergy for our power purchase agreement obligation and our DOE liability and other forms of involvement. As a result, we entered into a purchase and sale agreement with Petroleos de Venezuela, S.A.,accounted for the Palisades plant, which is owned by the Bolivarian Republic of Venezuela,real estate asset subject to sell our ownership interest in SENECAthe leaseback, as a financing for accounting purposes and certain associated generating equipment for $106 million. We closednot a sale. As a financing, no gain on the sale in April 2007.of Palisades was recognized on the Consolidated Statements of Income (Loss). We accounted for the remaining non-real estate assets and liabilities associated with the transaction as a sale.
As a financing, the Palisades plant remains on our Consolidated Balance Sheets and we continue to depreciate it. We recorded the related proceeds as a finance obligation with payments recorded to interest expense and the finance obligation based on the amortization of the obligation over the life of the Palisades power purchase agreement. The book value of thesethe finance obligation was based on an allocation of the transaction proceeds to the fair values of the net assets at March 31,sold and fair value of the Palisades plant asset under the financing. As of June 30, 2007, the financing obligation was approximately $55$194 million. PENDING ASSET SALES: In April 2007, weWe estimate future payments of $13 million per year over the next five years.
Subsequent Asset Sales: We entered into an agreement to sell CMS Energy Brasilour investment in GasAtacama to Endesa S.A. for $211gross cash proceeds of $80 million in July 2007. We closed on the sale of GasAtacama in August 2007.
Pending Asset Sales: We entered into an agreement to CPFL Energia S.A., a Brazilian utility.sell our investment Jamaica to AEI for gross cash proceeds of $14 million in June 2007. We expect to close on the sale by the end of 2007.
Discontinued Operations
In accordance with SFAS No. 144, our consolidated financial statements have been reclassified for all periods presented to reflect the second quarteroperations, assets and liabilities of 2007, subject to approval by the Brazilian national regulatory agency. The book value of these assets at March 31, 2007 was approximately $195 million, which includes a cumulative net foreign currency translation loss of $63 million. We also announced plans to conduct an auction to sell our GasAtacama combined gas pipeline and power generation businesses in Argentina and Chile, and our electric generating plant in Jamaica. We expect to complete the sale of these businesses by the end of 2007. Our pending asset sales are subject to the receipt of all necessary governmental, lender and partner approvals. We plan to use the proceeds from the pending asset sales to invest in our utility business and reduce parent company debt.

IMPAIRMENT CHARGES
Impairment Charges
We record an asset impairment when we determine that the expected future cash flows from an asset would be insufficient to provide for recovery of the asset'sasset’s carrying value. An asset held-in-use is evaluated for impairment by calculating the undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. If the undiscounted future cash flows are less than the carrying amount, we recognize an impairment loss. The impairment loss recognized is the amount by CMS-42 CMS Energy Corporation which the carrying amount exceeds the fair value. We estimate the fair market value of the asset utilizing the best information available. This information includes quoted market prices, market prices of similar assets, and discounted future cash flow analyses. The assets written down include certain equity method and other investments. There were no asset impairments recorded for the three months ended March 31, 2006.

3: CONTINGENCIES
SEC ANDand DOJ INVESTIGATIONS: Investigations:During the period of May 2000 through January 2002, CMS MST engaged in simultaneous, prearranged commodity trading transactions in which energy commodities were sold and repurchased at the same price. These so calledso-called round-trip trades had no impact on previously reported consolidated net income, earnings per share or cash flows, but had the effect of increasing operating revenues and operating expenses by equal amounts.
CMS Energy is cooperating with an investigation by the DOJ concerning round-trip trading, which the DOJ commenced in May 2002. CMS Energy is unable to predict the outcome of this matter and what effect, if any, this investigation will have on its business. In March 2004, the SEC approved a cease-and-desist order settling an administrative action against CMS Energy related to round-trip trading. The order did not assess a fine and CMS Energy neither admitted to nor denied the order'sorder’s findings. The settlement resolved the SEC investigation involving CMS Energy and CMS MST. Also in March 2004, the SEC filed an action against three former employees related to round-trip trading at CMS MST. One of the individuals has settled with the SEC. CMS Energy is currently advancing legal defense costs for the remaining two individuals in accordance with existing indemnification policies. Those two individuals filed a motion to dismiss the SEC action, which was denied. SECURITIES CLASS ACTION LAWSUITS:
Securities Class Action Lawsuits: Beginning in May 2002, a number of complaints were filed against CMS-43 CMS Energy Corporation CMS Energy, Consumers and certain officers and directors of CMS Energy and its affiliates in the United States District Court for the Eastern District of Michigan. The cases were consolidated into a single lawsuit (the "Shareholder Action"“Shareholder Action”), which generally seeks unspecified damages based on allegations that the defendants violated United States securities laws and regulations by making allegedly false and misleading statements about CMS Energy'sEnergy’s business and financial condition, particularly with respect to revenues and expenses recorded in connection with round-trip trading by CMS MST. In January 2005, the court granted a motion to dismiss Consumers and three of the individual defendants, but denied the motions to dismiss CMS Energy and the 13 remaining individual defendants. In March 2006, the court conditionally certified a class consisting of "all“all persons who purchased CMS Common Stock during the period of October 25, 2000 through and including May 17, 2002 and who were damaged thereby." The court excluded purchasers of CMS Energy'sEnergy’s 8.75 percent Adjustable Convertible Trust Securities ("ACTS"(“ACTS”) from the class and, in response, a new class action lawsuit was filed on behalf of ACTS purchasers (the "ACTS Action"“ACTS Action”) against the same defendants named in the Shareholder Action. The settlement described in the following paragraph, if approved, will resolve both the Shareholder and ACTS Actions.

CMS-48


CMS Energy Corporation
On January 3, 2007, CMS Energy and other parties entered into a Memorandum of Understanding (the "MOU"“MOU”), subject to court approval, regarding settlement of the two class action lawsuits. The settlement was approved by a special committee of independent directors and by the full board of directors of CMS Energy. Both judged that it was in the best interests of shareholders to eliminate this business uncertainty. The MOU is expected to lead to a detailed stipulation of settlement that will be presented to the assigned federal judge and the affected class in the second quarter of 2007. Under the terms of the MOU, the litigation will be settled for a total of $200 million, including the cost of administering the settlement and any attorney fees the court awards. CMS Energy will make a payment of approximately $123 million plus an amount equivalent to interest on the outstanding unpaid settlement balance beginning on the date of preliminary approval ofby the court and running until the balance of the settlement funds is paid into a settlement account. In entering into the MOU, CMS Energy makes no admission of liability under the Shareholder Action and the ACTS Action. The parties executed a Stipulation and Agreement of Settlement dated May 22, 2007 (“Stipulation”) incorporating the terms of the MOU. On May 30, 2007, plaintiffs filed a “Motion for Order Preliminarily Approving Stipulation and Agreement of Settlement.” On June 7, 2007, the court entered a “Preliminary Order in Connection with Settlement Proceedings and Proposed Class Certification,” in which the court preliminarily approved the Stipulation and scheduled the settlement fairness hearing for September 6, 2007. In accordance with the Stipulation, CMS has paid approximately $1 million of the settlement amount to fund administrative expenses. The remaining $199 million and interest accruing thereon from the date of the June 7, 2007 order is payable ten business days after entry of the Order and Final Judgment following the September 6, 2007 hearing.
Out of the total settlement, CMS Energy'sEnergy’s insurers will pay approximately $77 million directly to the settlement account. CMS Energy took an approximate $123 million net pre-tax charge to 2006 earnings in the fourth quarter of 2006. In entering into the MOU, CMS Energy makes no admission of liability under the Shareholder Action and the ACTS Action. At March 31,June 30, 2007, we have a receivable of $77 million and a legal settlement liability of $200$199 million recorded on our Consolidated Balance Sheets. GAS INDEX PRICE REPORTING INVESTIGATION:
Gas Index Price Reporting Investigation:CMS Energy has notified appropriate regulatory and governmental agencies that some employees at CMS MST and CMS Field Services appeared to have provided inaccurate information regarding natural gas trades to various energy industry publications, which compile and report index prices. CMS Energy is cooperatingcooperated with an investigation by the DOJ regarding this matter. Although CMS Energy has not received any formal notification that the DOJ has completed its investigation, the DOJ’s last request for information occurred in November 2003, and CMS Energy completed its response to this request in May 2004. CMS Energy is unable to predict the outcome of the DOJ investigation and what effect, if any, the investigation will have on its business.
The CFTC filed a civil injunctive action against two former CMS Field Services employees in Oklahoma federal district court on February 1, 2005. The action alleges the two engaged in reporting false natural gas trade information, and seeks to enjoinprohibit these acts, compel compliance with the Commodities Exchange Act, and impose monetary penalties. Trial dates have been held in abeyance pending settlement discussions. CMS Energy is currently advancing legal defense costsThe court entered separate consent orders with respect to each of the two individuals, one dated April 18, 2007 and one dated June 25, 2007, resolving this litigation. The consent orders prohibit each of the individuals from engaging in accordancecertain activities and further provide civil monetary penalties in the amount of $100,000 for one individual and $25,000 for the other individual. Pursuant to agreements with existing indemnification policies. CMS-44 each of the individuals, CMS has paid $95,000 of the $100,000 amount and $22,000 of the $25,000 amount, with the remaining amounts paid by the individuals themselves. These settlements put an end to CFTC enforcement actions relating to gas price reporting by individuals once employed at present or former CMS subsidiaries.
Katz Technology Litigation:In June 2007, Ronald A. Katz Technology Licensing, L.P. (“RAKTL”), filed a lawsuit in the United States District Court for the Eastern District of Michigan against CMS Energy and Consumers alleging patent infringement. RAKTL is claiming that automated customer service, bill payment services and gas leak reporting offered to our customers and accessed through toll free numbers infringe patents held by RAKTL. This case has been recently transferred to the U.S.

CMS Energy Corporation BAY HARBOR:
District Court for Central District of California where other similar cases against public utilities, banks and other entities involving these patents are pending. We obtained an opinion from patent counsel that our automated telephone systems do not infringe on RAKTL patents and that those patents may be invalid. We will defend ourselves vigorously against these claims but cannot predict their outcome.
Bay Harbor:As part of the development of Bay Harbor by certain subsidiaries of CMS Energy, which went forward under an agreement with the MDEQ, third parties constructed a golf course and a park over several abandoned CKD piles, left over from the former cement plant operation on the Bay Harbor site. Pursuant to the agreement with the MDEQ, a water collection system was constructed to recover seep water from one of the CKD piles and CMS Energy built a treatment plant to treat the seep water. In 2002, CMS Energy sold its interest in Bay Harbor, but retained its obligations under previous environmental indemnifications entered into at the inception of the project.
In September 2004, the MDEQ issued a notice of noncompliance after finding high-pH seep water in Lake Michigan adjacent to the property. The MDEQ also found higher than acceptable levels of heavy metals, including mercury, in the seep water.
In February 2005, the EPA executed an AOC to address problems at Bay Harbor, upon the consent of CMS Land Company (CMS Land) and CMS Capital, LLC, both subsidiaries of CMS Energy. Pursuant to the AOC, the EPA approved a Removal Action Work Plan in July 2005. Among other things, this plan calls for the installation of collection trenches to intercept high-pH CKD leachate flow to the lake. All collection systems contemplated in this work plan have been installed. Shoreline effectiveness monitoring is ongoing, and CMS Land is obligated to address any observed exceedances in pH. This may potentially include the augmentation of the collection system. In May 2006, the EPA approved a pilot carbon dioxide augmentation plan to augment the leachate recovery system by improving pH results in the Pine Court area of the collection system. The augmentation system was installed in June 2006.
In February 2006, CMS Land submitted to the EPA a proposed Remedial Investigation and Feasibility Study for the East Park CKD pile. The EPA approved a schedule for near-term activities, which includes consolidating certain CKD materials and installing collection trenches in the East Park leachate release area. In June 2006, the EPA approved an East Park CKD Removal Action Work Plan and Final Engineering Design for Consolidation. CMS Energy and the MDEQ have initiated negotiations of an AOC and to define a long-term remedy at East Park.
CMS Land has entered into various access, purchase and settlement agreements with several of the affected landowners at Bay Harbor, and entered into a confidential settlement with one landowner to resolve a lawsuit filed by that landowner. CMS has received demands for indemnification relating to claims and/or lawsuits filed by a property owner and a former business owner at Bay Harbor. CMS Land has purchased five unimproved lots and two lots with houses. At this time, CMS Land believes it has all necessary access arrangements to complete the remediation work required under the AOC.
CMS Energy recorded charges related to this matter in 2004, 2005, 2006 totaling $93 million. At March 31,June 30, 2007, CMS Energy has a liability of $48$44 million for its remaining obligations. We based the liability on 2006 discounted costs, using a discount rate of 4.7 percent and an inflation rate of 1 percent on annual operating and maintenance costs. We used the interest rate for 30-year U.S. Treasury securities for the discount rate. The undiscounted amount of the remaining obligation is $62$57 million. We expect to pay $18 million in 2007, $17 million in 2008, $3 million in 2009, and the remaining expenditures as part of long-term operating and maintenance costs. Any significant change in assumptions, such as an increase in the number of sites, different remediation techniques, nature and extent of contamination, inability to reach agreement with the MDEQ or EPA over remedial actions,

and legal and regulatory requirements, could impact our estimate of remedial action costs and the timing of the expenditures. An adverse outcome of this matter could, depending on the size of any indemnification obligation or liability under environmental laws, have a potentially significant adverse effect on CMS Energy'sEnergy’s financial condition and liquidity and could negatively impact CMS Energy'sEnergy’s financial results. CMS Energy cannot predict the ultimate cost or outcome of this matter. CMS-45 CMS Energy Corporation CONSUMERS' ELECTRIC UTILITY CONTINGENCIES ELECTRIC ENVIRONMENTAL MATTERS:
Consumers’ Electric Utility Contingencies
Electric Environmental Matters:Our operations are subject to environmental laws and regulations. Costs to operate our facilities in compliance with these laws and regulations generally have been recovered in customer rates.
Routine Maintenance Classification:The EPA has alleged that some utilities have incorrectly classified plant modifications as "routine maintenance"“routine maintenance” rather than seeking permits from the EPA to modify the plant from the EPA.plant. We have received and responded to information requests from the EPA on this subject. We believe that we have properly interpreted the requirements of "routine“routine maintenance." If our interpretation is found to be incorrect, we may be required to install additional pollution controls at some or all of our coal-fired electric generating plants and potentially pay fines. Additionally, the viability of certain plants remaining in operation could be called into question.
Cleanup and Solid Waste:Under the Michigan Natural Resources and Environmental Protection Act, we expect that we will ultimately incur investigation and remedial action costs at a number of sites. We believe that these costs will be recoverable in rates under current ratemaking policies.
We are a potentially responsible party at several contaminated sites administered under the Superfund. Superfund liability is joint and several, meaning that many other creditworthy parties with substantial assets are potentially responsible with respect to the individual sites. Based on our experience, we estimate that our share of the total liability for the known Superfund sites will be between $1 million and $10 million. At March 31,June 30, 2007, we have recorded a liability for the minimum amount of our estimated probable Superfund liability in accordance with FIN 14. The timing of payments related to the remediation of our Superfund sites is uncertain. Any significant change in assumptions, such as different remediation techniques, nature and extent of contamination, and legal and regulatory requirements, could affect our estimate of remedial action costs and the timing of our remediation payments.
Ludington PCB:In October 1998, during routine maintenance activities, we identified PCB as a component in certain paint, grout, and sealant materials at Ludington. We removed and replaced part of the PCB material. Since proposing a plan to deal with the remaining materials, we have had several conversations with the EPA. The EPA has proposed a rule which would authorize continued use of such material in place, subject to certain restrictions. We are not able to predict when a final rule will be issued.
Electric Utility Plant Air Permit Issues:In April 2007, we received a Notice of Violation/Finding of Violation from the EPA alleging that fourteen of our utility boilers exceeded visible emission limits in their associated air permits. The utility boilers are located at the D.E. Karn/J.C. Weadock Generating Complex, the J.H. Campbell Plant, the BC Cobb Electric Generating Station and the JR Whiting Plant. We are preparing forpresently having discussions with the EPA regarding these allegations, but cannot predict the financial impact or outcome of this issue. LITIGATION:
Litigation:In 2003, a group of eight PURPA qualifying facilities (the plaintiffs), which sell power to us, filed a lawsuit in Ingham County Circuit Court. The lawsuit alleged that we incorrectly calculated the energy charge payments made pursuant to power purchase agreements with qualifying facilities.

CMS-51


CMS Energy Corporation
The judge deferred to the primary jurisdiction of the MPSC, dismissing the circuit court case without prejudice. In February 2005, the MPSC issued an order in the 2004 PSCR plan case concluding that we have been correctly administering the energy charge calculation methodology. The plaintiffs have appealed the MPSC order to the Michigan Court of Appeals. The plaintiffs also filed suit in the United CMS-46 CMS Energy Corporation States Court for the Western District of Michigan, which the judge subsequently dismissed on the basis that the pending state court litigation would fully resolve any federal issue before the courts. The plaintiffs then appealed the dismissal to the United States Court of Appeals, which held that the district court matter should be stayed rather than dismissed, pending the outcome of the state appeal. We cannot predict the outcome of these appeals. CONSUMERS' ELECTRIC UTILITY RATE MATTERS ELECTRIC
Consumers’ Electric Utility Rate Matters
Electric ROA:The Customer Choice Act allows electric utilities to recover their net Stranded Costs. In prior orders, the MPSC approved recovery of Stranded Costs incurred from 2002 through 2003 plus the cost of money through the period of collection. At March 31,June 30, 2007, we had a regulatory asset for Stranded Costs of $66$67 million on our Consolidated Balance Sheets. We collect these Stranded Costs through a surcharge on ROA customers. At March 31,June 30, 2007, alternative electric suppliers were providing 283302 MW of generation service to ROA customers, which represent a decrease of 193 percent of ROA load compared to March 31,June 30, 2006. This downward trend has affected negatively our ability to recover timely ourthese Stranded Costs. If downward ROA trends continue, it may require legislative or regulatory assistance to recover fully our Stranded Costs. However, the Customer Choice Act allows electric utilities to recover their net Stranded Costs. It is difficult to predict future ROA customer trends and their effect on the timely recovery of Stranded Costs. POWER SUPPLY COSTS:
Power Supply Costs:To reduce the risk of high power supply costs during peak demand periods and to achieve our reserve margin target, we purchase electric capacity and energy contracts for the physical delivery of electricity primarily in the summer months and to a lesser degree in the winter months. We have purchased capacity and energy contracts covering the reserve margin requirements for 2007 and covering partially the estimated reserve margin requirements for 20072008 through 2010. As a result, we have an asset of $62 million for unexpired seasonal capacity and energy contracts at March 31, 2007. As of March 31,June 30, 2007, we expect capacity costs for these primarily seasonal electric capacity and energy contracts to be $14$17 million for 2007.

2007 PSCR Plan:In September 2006, we filed our 2007 PSCR plan with the MPSC. The plan sought CMS-47 CMS Energy Corporation authorization to incorporate our 2005 and 2006 PSCR underrecoveries into our 2007 PSCR monthly factor. In December 2006, the MPSC issued a temporary order allowing us to implement our 2007 PSCR monthly factor on January 1, 2007, as filed. The order also allowed us to continue to roll in prior year underrecoveries and overrecoveries in future PSCR plans.
Underrecoveries in power supply costs are included in Accrued power supply and gas revenue on our Consolidated Balance Sheets. We expect to recover fully all of our PSCR costs. When we are unable to collect these costs as they are incurred, there is a negative impact on our cash flows from electric utility operations. We cannot predict the outcome of these proceedings. ELECTRIC RATE CASE:
Electric Rate Case:In March 2007, we filed an application with the MPSC seeking an 11.25 percent authorized return on equity and an annual increase in revenues of $157 million as shown inmillion. In May 2007, we filed supplemental testimony with the following table: MPSC to include transaction costs from the sale of Palisades. In July 2007, we filed an amended application with the MPSC to include the proposed purchase of the Zeeland power plant, the approval of an energy efficiency program, and to make other revisions.
In July 2007, we also filed a motion for partial and immediate rate relief, which seeks the following:
In Millions ----------- Components
approval to remove the costs associated with Palisades,
recovery of the proposed purchase of the Zeeland power plant,
partial and immediate rate relief associated with 2007 capital investments, a $400 million equity infusion into Consumers, and general inflation on operation and maintenance expenses to 2007 levels, and
approval of a plan for the distribution of $127 million of proceeds from the sale of Palisades to customers, effectively offsetting the partial and immediate relief for up to nine months.

(b) The nuclear surcharge is a proposal to earn a return on funds spent on Big Rock spent nuclear fuel storage, decommissioning, and site restoration expenditures until pending DOE litigation and future MPSC proceedings regarding this issue are concluded. (c) Palisades power purchase agreement costs are currently offset through feedback in the PSCR related to Palisades base rate revenues via a base rate recovery credit. The Palisades base rate recovery credit will be discontinued once Palisades' costs are removed from base rates. If approved as requested, the rate requests would go into effect in January 2008 and would apply to all retail electric customers.
We cannot predict the amount or timing of any MPSC decision on the requests. OTHER CONSUMERS' ELECTRIC UTILITY CONTINGENCIES THE
Other Consumers’ Electric Utility Contingencies
The MCV PPA:The MCV Partnership, which leases and operates the MCV Facility, contracted to sell 1,240 MW of electricity to Consumers under a 35-year power purchase agreement beginning in 1990. We estimate that capacity and energy payments under the MCV PPA will be $620 million per year. The MCV PPA and the associated customer rates are unaffected by the November 2006 sale of our interest in the MCV Partnership.
Underrecoveries related to the MCV PPA:The cost that we incur under the MCV PPA exceeds the recovery amount allowed by the MPSC. We estimate cash underrecoveries of our capacity and fixed energy payments of $39 million in 2007 of which we have expensed $13$30 million during the threesix months ended March 31,June 30, 2007. However, we use savings from the RCP, after allocating a portion to CMS-48 CMS Energy Corporation customers, to offset a portion of our capacity and fixed energy underrecoveries expense.
We recover from our customers the capacity and fixed energy charges based on availability, up to an availability cap of 88.7 percent as established in previous MPSC orders. The MCV Partnership has filed an application with the MPSC requesting the elimination of the 88.7 percent availability cap. We cannot predict the outcome of this matter.
RCP:In January 2005, we implemented the MPSC-approved RCP with modifications. The RCP allows us to recover the same amount of capacity and fixed energy charges from customers as approved

CMS-54


CMS Energy Corporation
in prior MPSC orders. However, we are able to dispatch the MCV Facility based on natural gas market prices. This results in fuel cost savings for the MCV Facility, which the MCV Partnership shares with us. The RCP also requires us to contributecontributions of $5 million annually to a renewable resources program. As of MarchJune 30, 2007, we have contributedcontributions of $12 million were made to the renewable resources program. The underlying RCP agreement between Consumers and the MCV Partnership extends through the term of the MCV PPA. However, either party may terminate that agreement under certain conditions. In January 2007, the Michigan Attorney General filed an appeal with the Michigan Supreme Court regarding the MPSC'sMPSC’s order approving the RCP. We cannot predictThe Supreme Court denied the outcome of thisAttorney General’s request to further consider the matter. Regulatory Out
Regulatory-out Provision in the MCV PPA:After September 15, 2007, we expect to claim relief under the regulatory outregulatory-out provision in the MCV PPA, thereby limiting our capacity and fixed energy payments to the MCV Partnership to the amounts that we collect from our customers. The MCV Partnership has notified us that it takes issue withopposes our intended exercise of the regulatory outregulatory-out provision. We believe that the provision is valid and fully effective, but cannot assure that itwe will prevail in the event of a dispute. If we are successful in exercising the regulatory outregulatory-out provision, the MCV Partnership may, under certain circumstances, have the right to terminate or reduce the amount of capacity sold under the MCV PPA from 1,240 MW to 806 MW, which could affect our reserve margin. Presently, we are in arbitration with the MCV Partnership regarding a dispute on the timing of MCV Partnership’s termination rights prescribed in the MCV PPA.
We anticipate that the MPSC will review our exercise of the regulatory outregulatory-out provision and the likely consequences of such action in 2007. It is possible that in the event that the MCV Partnership ceases performance under the MCV PPA, prior orders could limit recovery of replacement power costs to the amounts that the MPSC authorized for recovery under the MCV PPA. Depending on the cost of replacement power, this could result in our costs exceeding the recovery amount allowed by the MPSC. We cannot predict the outcome of these matters.
To comply with a prior MPSC order, we made a filing in May 2007 with the MPSC, which asked the MPSC to make a determination regarding whether it wished to reconsider the amount of the MCV PPA payments that we recover from customers. We are unable to predict the outcome of this request. THE SALE OF NUCLEAR ASSETS AND THE PALISADES POWER PURCHASE AGREEMENT: Sale of
Nuclear Assets: In April 2007, we sold Palisades to Entergy for $380 million. The final purchase price was subject to various closing adjustments such as working capital and capital expenditure adjustments and nuclear fuel usage and inventory adjustments resulting in us receiving $361 million. We also paid Entergy $30 million to assume ownership and responsibility for the Matters:Big Rock ISFSI. Because of the sale of Palisades, we will also pay the NMC, the former operator of the Palisades plant, $7 million in exit fees and will forfeit our investment in the NMC of $5 million. Entergy will assume responsibility for the future decommissioning of the Palisades plant and for storage and disposal of spent nuclear fuel located at the Palisades and the Big Rock ISFSI sites. At closing, we transferred $252 million in decommissioning trust fund balances to Entergy. The MPSC order approving the Palisades transaction allows us to recover the estimated $314 million book value of the Palisades plant. As a result, we estimate that we will credit excess proceeds of $66 million to our retail customers through refunds applied over the remainder of 2007 and 2008. The MPSC order deferred ruling on the recovery of $30 million in estimated transaction costs, including the NMC exit fees, and the $30 million payment to Entergy related to the Big Rock ISFSI until the next general rate case. We will defer these costs as a regulatory asset on our Consolidated Balance Sheets as recovery is probable. CMS-49 CMS Energy Corporation In April 2007, the NRC, through its staff, issued an order approving the transfer of the Palisades operating license. Subsequently, in April 2007, the NRC issued an order requiring that certain intervenors be given, under a protective order, information related to the buyer's financial capability. If, after the review of the information, the intervenors wished to seek additional proceedings on the license transfer, the NRC would consider the request. The NRC did not alter or stay the prior order approving the license transfer. We believe that it is unlikely that the NRC will conduct further proceedings, but we cannot predict the outcome of the matter. These events did not hold up the closing of the sale of Palisades. The following table summarizes the estimated impacts of the Palisades and the Big Rock ISFSI transactions:
In Millions - ----------------------------------------------------------------------------------- Customer Benefits (a) Deferred costs - --------------------- -------------- Purchase price $380 NMC exit fee $ 7 Less: Estimated book value of Palisades plant 314 Forfeiture of the NMC investment 5 ---- Excess proceeds to be refunded to customers 66 (b) Estimated selling expenses 18 Big Rock ISFSI operation and maintenance fee to Excess decommissioning trust funds to be refunded to customers 189 (c) Entergy 30 ---- --- Total estimated customer refunds $255 Total regulatory asset $60 ==== ===
(a) In the FERC's February 2007 order regarding the Palisades transaction, the FERC granted our request to apply $11 million in FERC decommissioning trust fund balances for the Palisades plant toward the Big Rock decommissioning shortfall, as described in "Big Rock Nuclear Plant Decommissioning" within this section. The order was contingent upon the NRC approving the transfer of operating licenses, which the NRC approved in April 2007. This determination is the subject of a clarification request filed by a wholesale customer with the FERC. (b) Final proceeds in excess of the book value are subject to closing adjustments and review by the MPSC. (c) In the MPSC's March 2007 order approving the Palisades transaction, the MPSC indicated that $189 million of MPSC jurisdictional decommissioning funds must be credited to our retail customers through refunds applied over the remainder of 2007 and 2008. Final disposition of these funds is subject to closing date balances and is subject to review by the MPSC. The remaining estimated $116 million of the MPSC jurisdictional decommissioning funds, which is subject to closing date reconciliation will be used to benefit our retail customers and is expected to be addressed in a separate filing made with the MPSC. Palisades Power Purchase Agreement: Entergy contracted to sell us 100 percent of the plant's output up to its current annual average capacity of 798 MW under a 15-year power purchase agreement beginning in April 2007. We provided $30 million in security to Entergy for our power purchase agreement obligation in the form of a letter of credit. We estimate that capacity and energy payments under the Palisades power purchase agreement will be $300 million per year. Because of the Palisades power purchase agreement, the transaction is a sale and leaseback for accounting purposes. SFAS No. 98 specifies the accounting required for a seller's sale and simultaneous leaseback involving real estate. We will have continuing involvement with the Palisades plant through security provided to Entergy for our power purchase agreement obligation, our DOE liability, and other forms of involvement. As a result, we will account for the Palisades plant, which is CMS-50 CMS Energy Corporation the real estate asset subject to the leaseback, as a financing for accounting purposes and not a sale. We will account for the remaining non-real estate assets and liabilities associated with the transaction as a sale. As a financing, the Palisades plant will remain on our Consolidated Balance Sheets and the related proceeds will be recorded as a financing obligation. The value of the finance obligation is based on an allocation of the transaction proceeds to the fair values of the net assets sold and fair value of the Palisades plant assets under the financing. BIG ROCK NUCLEAR PLANT DECOMMISSIONING: Decommissioning:
The MPSC and the FERC regulate the recovery of costs to decommission the Big Rock nuclear plant.Rock. In December 2000, funding of the Big Rock trust fund stopped because the MPSC-authorized decommissioning surcharge collection period expired. In a March 2007 report to the MPSC, we indicated that we have managed the decommissioning trust fund to meet the annual NRC financial assurance requirements by withdrawing NRC radiological decommissioning costs from the trust fund and initially funding non-NRC greenfield costs out of corporate funds. In March 2006, we contributed corporate funds of $16 million to the trust fund to support the NRC radiological decommissioning costs. Excluding the additional nuclear fuel storage costs due to the DOE's failure to accept spent nuclear fuel on schedule, we are projecting theThe level of funds provided by the trust will fallfell short of the amount needed to complete decommissioning by an additional $36 million.

As a result, we provided $50 million of $52 million, which arecorporate contributions for costs associated with NRC radiological and non-NRC greenfield decommissioning work are being funded outas of June 30, 2007.

We plan to seek recovery of expenditures that we have funded in future filings with the MPSC and have a $36$122 million regulatory asset recorded on our Consolidated Balance Sheets as of March 31,June 30, 2007. Cost projections
Actual expenditures for Big Rock indicate a decommissioning cost of $389totaled $387 million as of March 2007, of which we have incurred $387 million. These amounts excludeJune 30, 2007. This total excludes the additional costs for spent nuclear fuel storage due to the DOE'sDOE’s failure to accept this spent nuclear fuel on schedule. They also exclude post September 11schedule as well as certain increased security costs that we are recovering through the security cost recovery provisions of Public Act 609 of 2002. These activities had no material impact on consolidated net income. Any remaining Big Rock decommissioning costs will initially be funded out of corporate funds. NUCLEAR MATTERS:
Nuclear Fuel Cost:We amortized nuclear fuel cost to fuel expense based on the quantity of heat produced for electric generation. For nuclear fuel used after April 6, 1983, we charged certain disposal costs to nuclear fuel expense, recovered these costs through electric rates, and remitted them to the DOE quarterly. We elected to deferdeferred payment for disposal of spent nuclear fuel burned before April 7, 1983. Our DOE liability is $154$156 million at March 31,June 30, 2007. This amount includes interest, which is payable upon the first delivery of spent nuclear fuel to the DOE. We have recovered, through electric

CMS Energy Corporation
rates, the amount of this liability, excluding a portion of interest. In conjunction with the sale of Palisades and the Big Rock ISFSI, we retained this obligation and provided $155 million in security to Entergy for this obligation in the form of a letter of credit.
DOE Litigation:In 1997, a U.S. Court of Appeals decision confirmed that the DOE was to begin accepting deliveries of spent nuclear fuel for disposal by January 1998. Subsequent U.S. Court of Appeals litigation, in which we and other utilities participated, has not been successful in producing more specific relief for the DOE'sDOE’s failure to accept the spent nuclear fuel.
There are twoseveral court decisions that support the right of utilities to pursue damage claims in the United States Court of Claims against the DOE for failure to take delivery of spent nuclear fuel. Over 60 utilities have initiated litigation in the United States Court of Claims. We filed our complaint in December 2002. If our litigation against the DOE is successful, we plan to use any recoveries as reimbursement for the incurred costs of spent nuclear fuel storage during our ownership of Palisades CMS-51 CMS Energy Corporation and Big Rock. We can make no assurance that the litigation against the DOE will be successful. The sale of Palisades and the Big Rock ISFSI did not transfer the right to any recoveries from the DOE related to costs of spent nuclear fuel storage incurred during our ownership of Palisades and Big Rock.
In 2002, the site at Yucca Mountain, Nevada was designated for the development of a repository for the disposal of high-level radioactive waste and spent nuclear fuel. We expect that the DOE, in due course,ultimately, will submit a final license application to the NRC for the repository. The application and review process is estimated to take several years. Insurance: We maintained nuclear insurance coverage on our nuclear plants until Palisades and the Big Rock ISFSI were sold in April 2007. At Palisades, we maintained nuclear property insurance from NEIL totaling $2.750 billion and insurance that would partially cover the cost of replacement power during certain prolonged accidental outages. Because NEIL is a mutual insurance company, we could be subject to assessments of up to $30 million in any policy year if insured losses in excess of NEIL's maximum policyholders surplus occur at our, or any other member's, nuclear facility. NEIL's policies include coverage for acts of terrorism. At Palisades, we maintained nuclear liability insurance for third-party bodily injury and off-site property damage resulting from a nuclear energy hazard for up to approximately $10.761 billion, the maximum insurance liability limits established by the Price-Anderson Act. Part of the Price-Anderson Act's financial protection is a mandatory industry-wide program under which owners of nuclear generating facilities could be assessed if a nuclear incident occurs at any nuclear generating facility. The maximum assessment against us could be $101 million per occurrence, limited to maximum annual installment payments of $15 million. We also maintained insurance under a program that covers tort claims for bodily injury to nuclear workers caused by nuclear hazards. The policy contains a $300 million nuclear industry aggregate limit. Under a previous insurance program providing coverage for claims brought by nuclear workers, we remain responsible for a maximum assessment of up to $6 million. This requirement will end December 31, 2007. Big Rock was insured for nuclear liability up to $544 million through nuclear insurance and the NRC indemnity, and we maintained a nuclear property insurance policy from NEIL. Insurance policy terms, limits, and conditions are subject to change during the year as we renew our policies. CONSUMERS' GAS UTILITY CONTINGENCIES GAS ENVIRONMENTAL MATTERS:
Consumers’ Gas Utility Contingencies
Gas Environmental Matters:We expect to incur investigation and remediation costs at a number of sites under the Michigan Natural Resources and Environmental Protection Act, a Michigan statute that covers environmental activities including remediation. These sites include 23 former manufactured gas plant facilities. We operated the facilities on these sites for some part of their operating lives. For some of these sites, we have no current ownership or may own only a portion of the original site. In 2005, we estimated our remaining costs to be between $29 million and $71 million, based on 2005 discounted costs, using a discount rate of three percent. The discount rate represents a 10-year average of U.S. Treasury bond rates reduced for increases in the consumer price index. We expect to fund most of these costs through proceeds derived from a settlement with insurers and MPSC-approved rates. At March 31,June 30, 2007, we have a liability of $22$21 million, net of $60$61 million of expenditures incurred to date, CMS-52 CMS Energy Corporation and a regulatory asset of $55$53 million. The timing of payments related to the remediation of our manufactured gas plant sites is uncertain. Any significant change in assumptions, such as an increase in the number of sites, different remediation techniques, nature and extent of contamination, and legal and regulatory requirements, could affect our estimate of remedial action costs and the timing of our remediation payments. CONSUMERS' GAS UTILITY RATE MATTERS GAS COST RECOVERY:

GCR plan for year 2005-2006:In November 2005, the MPSC issued an order for our 2005-2006 GCR Plan year, which resulted in approval of a settlement agreement and established a fixed price cap of $10.10 per mcf for the December 2005 through March 2006 billing period. We were able to maintain our GCR billing factor below the authorized level for that period. The order was appealed to the Michigan Court of Appeals by one intervenor. We are unable to predict the outcome of this proceeding.
GCR plan for year 2006-2007:In August 2006, the MPSC issued an order for our 2006-2007 GCR Plan year, which resulted in approval of a settlement agreement that allowed a base GCR ceiling factor of $9.48 per mcf for the 12-month period of April 2006 through March 2007. We were able to maintain our GCR billing factor below the authorized level for that period.
GCR plan for year 2007-2008:In December 2006, we filed an application with the MPSC seeking approval of a GCR plan for the 12-month period of April 2007 through March 2008. Our request proposed using a GCR factor consisting of: -
a base GCR ceiling factor of $8.47 per mcf, plus
a quarterly GCR ceiling price adjustment contingent upon future events.
In June 2007, all parties signed a settlement agreement and filed the agreement with the MPSC for approval. All parties agreed to lower the ceiling on the quarterly adjustment mechanism from $3.50 per mcf to $3.00 per mcf.
Due to an increase in NYMEX gas prices compared to the plan, the base GCR ceiling factor of $8.47increased to $8.67 per mcf plus - a quarterly GCRpursuant to the ceiling price adjustment contingent upon future events.

2007 GAS RATE CASE: Gas Rate Case:In February 2007, we filed an application with the MPSC seeking an 11.25 percent authorized return on equity along with an $88 million annual increase in our gas delivery and transportation rates, of which $17 million would be contributed to a low income energy efficiency fund.rates. We have proposed the use of a Revenue Decoupling and Conservation Incentive Mechanism for residential and general service rate classes, to help assure a reasonable opportunitywhich partially separates the collection of fixed costs from gas sales and enhances the utility’s ability to recover its fixed costs regardless.
The MPSC Staff and intervenors filed testimony on July 20, 2007. In its testimony, the MPSC Staff recommended a 10.5 percent authorized return on equity with a $35 million annual increase in our gas delivery and transportation rates. The schedule established by the MPSC for processing this case could allow for a final order by the end of sales levels. OTHER CONTINGENCIES GAS INDEX PRICE REPORTING LITIGATION: 2007.

Gas Index Price Reporting Litigation:CMS Energy, CMS MST, CMS Field Services, Cantera Natural Gas, Inc. (the company that purchased CMS Field Services) and Cantera Gas Company are named as defendants in various lawsuits arising as a result of claimed inaccurate natural gas price reporting. Allegations include manipulation of NYMEX natural gas futures and options prices, price-fixing conspiracies, and artificial inflation of natural gas retail prices in California, Colorado, Kansas, Missouri, Tennessee, and Wisconsin.

ARGENTINA: settlement and CMS has made its $700,000 settlement payment.
Argentina:As part of its energy privatization incentives, Argentina directed CMS Gas Transmission to calculate tariffs in U.S. dollars, then convert them to pesos at the prevailing exchange rate, and to adjust tariffs every six months to reflect changes in inflation. Starting in early 2000, Argentina suspended the inflation adjustments.
In January 2002, the Republic of Argentina enacted the Public Emergency and Foreign Exchange System Reform Act. This law repealed the fixed exchange rate of one U.S. dollar to one Argentine peso, converted all dollar-denominated utility tariffs and energy contract obligations into pesos at the same one-to-one exchange rate, and directed the Government of Argentina to renegotiate such tariffs.
CMS Gas Transmission began arbitration proceedings against the Republic of Argentina (Argentina) under the auspices of the International Centre for the Settlement of Investment Disputes (ICSID) in mid-2001, citing breaches by Argentina of the Argentine-U.S. Bilateral Investment Treaty (BIT). In May 2005, an ICSID tribunal concluded, among other things, that Argentina'sArgentina’s economic emergency did not excuse Argentina from liability for violations of the BIT. The ICSID tribunal found in favor of CMS Gas Transmission, and awarded damages of U.S. $133 million, plus interest.
The ICSID Convention provides that either party may seek annulment of the award based upon five possible grounds specified in the Convention. Argentina'sArgentina’s Application for Annulment was formally registered by ICSID on September 27, 2005. In March 2007, the Annulment matter was heard before a panel in Paris, and the matter is now before the panel pending a decision. CMS-54

On December 28, 2005, certain insurance underwriters paid the sum of $75 million to CMS Gas Transmission in respect of their insurance obligations resulting from non-payment of the ICSID award. The payment, plus interest, is subject to repayment by CMS Gas Transmission in the event that the ICSID award is annulled. Pending the outcome of the annulment proceedings, CMS Energy has recorded the $75 million payment as a long-term deferred credit. QUICKSILVER RESOURCES, INC.
Quicksilver Resources, Inc.:Quicksilver sued CMS MST for breach of contract in connection with a Contract for Sale and Purchase of natural gas, pursuant to which Quicksilver agreed to sell, and CMS MST agreed to buy, natural gas. Quicksilver believes that it is entitled to more payments for natural gas than it has received. CMS MST disagrees with Quicksilver'sQuicksilver’s analysis and believes that it has paid all amounts owed for delivery of gas pursuant to the contract. Quicksilver is seeking damages of up to approximately $126 million, plus prejudgment interest and attorney fees, which in our judgment is unsupported by the facts. fees.
The matter was tried before a jury intrial commenced on March 19, 2007. The jury made a finding that CMS MST has breached the agreement withverdict awarded Quicksilver but found that Quicksilver had failed to prove damages and accordingly awarded zero compensatory damages to Quicksilver. However, the jury awardedbut $10 million in punitive damage against CMS MST.damages. The jury found that CMS MST will opposebreached the contract and committed fraud but found no actual damage on account of either such claim.

The judicial rescission of punitive damages if no compensatory damages have been awarded.the contract caused CMS Energy to record a charge in the second quarter of 2007 of approximately $24 million, net of tax. To preserve its appellate rights, CMS MST filed a motion to modify, correct or reform the judgment and a motion for a judgment contrary to the jury verdict with the trial court. The trial court dismissed these motions. CMS MST has scheduledfiled a datenotice of appeal with the Texas Court of Appeals.

- ------------ (a) The majority of this amount arises from routine provisions in stock and asset sales agreements under which we indemnify the purchaser for losses resulting from claims related to tax disputes and the failure of title to the assets or stock sold by us to the purchaser. We believe the likelihood of a loss for any remaining indemnifications to be remote. (b) Standby letters of credit include letters of credit issued under an amended credit agreement with Citicorp USA, Inc.

At March 31,June 30, 2007, certain contracts contained provisions allowing us to recover, from third parties, amounts paid under the guarantees. For example, if we are required to purchase a property under a put option agreement, we may sell the property to recover the amount paid under the option.
We enter into various agreements containing tax and other indemnification provisions in connection with a variety of transactions, including the sale of our interests in the MCV Partnership and the FMLP. In April 2007, we soldFMLP and the sale of our interest in Palisades and the Big Rock ISFSI to Entergy. As part of the transaction, we entered into agreements containing tax and other indemnification provisions.ISFSI. While we are unable to estimate the maximum potential obligation related to these indemnities, we consider the likelihood that we would be required to perform or incur significant losses related to these indemnities and the guarantees listed in the preceding tables to be remote. Project Financing: We enter into various project-financing security arrangements such as equity pledge agreements and share mortgage agreements to provide financial or performance assurance to third parties on behalf of certain unconsolidated affiliates. Expiration dates for these agreements vary from March 2015 to June 2020 or terminate upon payment or cancellation of the obligation. Non-payment or other act of default by an unconsolidated affiliate would trigger enforcement of the security. If we were required to perform under these agreements, the maximum amount of our obligation under these agreements would be equal to the value of the shares relinquished to the guaranteed party at the time of default.

replaced its $500 million facility with a new $500 million credit facility in March 2007. The new facilities contain less restrictive covenants, and provide for lower fees and lower interest margins than the previous credit facilities. DIVIDEND RESTRICTIONS:
Dividend Restrictions:Under provisions of our senior notes indenture, at March 31,June 30, 2007, we had $400 millionpayment of unrestricted net assets available to pay common stock dividends.dividends was limited to $436 million. Our $300 million secured revolving credit facility restricted payments of dividends on our common stock during a 12-month period to $150 million. This restriction was removed with the new $300 million credit facility effective April 2, 2007.
Under the provisions of its articles of incorporation, at March 31,June 30, 2007, Consumers had $227$232 million of unrestricted retained earnings available to pay common stock dividends. The dividend restrictions in its CMS-58 CMS Energy Corporationsecured revolving credit facility were removed in March 2007. Provisions of the Federal Power Act and the Natural Gas Act effectively restrict dividends to the amount of Consumers'Consumers’ retained earnings. For the threesix months ended March 31,June 30, 2007, we received $94$135 million of common stock dividends from Consumers. PREFERRED STOCK:
Preferred Stock:In February 2007, our non-voting preferred subsidiary interest of $11 million was repurchased and redeemed for a cash payment of $32 million. The original $19 million addition to paid-in-capital was reversed and a $1 million redemption premium was charged to retained deficit. CONTINGENTLY CONVERTIBLE SECURITIES:
Contingently Convertible Securities:In MarchJune 2007, the $11.87 per share conversion trigger price contingency was met for our $250 million 4.50 percent contingently convertible preferred stock and the $12.81 per share conversion trigger price contingency was met for our $150 million 3.375 percent contingently convertible senior notes. As a result, these securities are convertible at the option of the security holders for the three months ending JuneSeptember 30, 2007, with the par value or principal payable in cash. As of AprilJuly 2007, none of the security holders have notified us of their intention to convert these securities.
Because the 3.375 percent senior notes are convertible on demand, they are classified as current liabilities. CAPITAL LEASE OBLIGATIONS:
Capital Lease Obligations:Our capital leases are comprised mainly of leased service vehicles, power purchase agreements,office furniture, and office furniture.gas pipeline capacity. At March 31,June 30, 2007, capital lease obligations totaled $64$63 million. SALE OF ACCOUNTS RECEIVABLE: We estimate future minimum lease payments to range between $10 million and $16 million per year over the next five years.
Sale of Accounts Receivable:Under a revolving accounts receivable sales program, Consumers sells certain accounts receivable to a wholly owned, consolidated, bankruptcy remote special purpose entity. In turn, the special purpose entity may sell an undivided interest in up to $325 million of the receivables. The special purpose entity sold $10 million ofno receivables at March 31,June 30, 2007 and $325 million of receivables at December 31, 2006. Consumers continues to service the receivables sold to the special purpose entity. The purchaser of the receivables has no recourse against Consumers'Consumers’ other assets for failure of a debtor to pay when due and no right to any receivables not sold. Consumers has neither recorded a gain or loss on the receivables sold nor retained an interest in the receivables sold.

Contingently Convertible Securities:For the three and six months ended March 31,June 30, 2007, we recorded a loss from continuing operations. Due to antidilution, there was no impact to diluted EPS from our contingently convertible securities. Assuming positive income from continuing operations, our contingently convertible securities dilute EPS to the extent that the conversion value, which is based on the average market price of our common stock, exceeds the principal or par value. Had there been positive income from continuing operations, our contingently convertible securities would have contributed an additional 19.120.6 million shares to the calculation of diluted EPS for the three months ended March 31,June 30, 2007 and 19.9 million shares for the six months ended June 30, 2007.
Stock Options, Warrants and Restricted Stock:For the three months ended March 31,June 30, 2007, due to antidilution, there was no impact to diluted EPS for 1.91.4 million shares of unvested restricted stock awards or for options and warrants to purchase 0.2 million shares of common stock. For the six months ended June 30, 2007, due to antidilution, there was no impact to diluted EPS for 1.4 million shares of unvested restricted stock awards or for options and warrants to purchase 0.4 million shares of common stock. For the three months ended March 31, 2006, due to antidilution, there was no impact to diluted EPS for 0.9 million shares of unvested restricted stock awards and for options and warrants to purchase 0.5 million shares of common stock.
An additional 1.40.9 million stock options at March 31,June 30, 2007 and 1.91.8 million stock options at March 31,June 30, 2006, were excluded from the diluted EPS calculation because the exercise price was greater than the average market price of our common stock. These stock options have the potential to dilute EPS in the future.
Convertible Debentures:For the three and six months ended March 31,June 30, 2007, due to antidilution, there was no impact to diluted EPS from our 7.75 percent convertible subordinated debentures.

6: FINANCIAL AND DERIVATIVE INSTRUMENTS FINANCIAL INSTRUMENTS: Financial and derivative instruments
Financial Instruments:The carrying amounts of cash, short-term investments, and current liabilities approximate their fair values because of their short-term nature. We estimate the fair values of long-term financial instruments based on quoted market prices or, in the absence of specific market prices, on quoted market prices of similar instruments or other valuation techniques.

(a) In preparation for the sale of Palisades, these investments also held cash and cash equivalents totaling $91 million at March 31, 2007. In April 2007, we sold Palisades and the Big Rock ISFSI to Entergy. Accordingly, we transferred $252 million in trust fund assets to Entergy. For additional details on the sale of Palisades and the Big Rock ISFSI, see Note 3, Contingencies, "Other Consumers' Electric Utility Contingencies - The Sale of Nuclear Assets and the Palisades Power Purchase Agreement." DERIVATIVE INSTRUMENTS:
Derivative Instruments:In order to limit our exposure to certain market risks, we may enter into various risk management contracts, such as swaps, options, futures, and forward contracts. These contracts, used primarily to manage our exposure to changes in interest rates, commodity prices, and currency exchange rates, are classified as either non-trading or trading. We enter into these contracts using established policies and procedures, under the direction of both: - an executive oversight committee consisting of senior management representatives, and - a risk committee consisting of business unit managers.
an executive oversight committee consisting of senior management representatives, and
a risk committee consisting of business unit managers.
The contracts we use to manage market risks may qualify as derivative instruments that are subject to derivative and hedge accounting under SFAS No. 133. If a contract is a derivative, it is recorded on our consolidated balance sheet at its fair value. We then adjust the resulting asset or liability each quarter to CMS-61 CMS Energy Corporation reflect any change in the market value of the contract, a practice known as marking the contract to market. From time to time, we enter into cash flow hedges. If a derivative qualifies for cash flow hedge accounting treatment, the changes in fair value (gains or losses) are reported in AOCL; otherwise, the changes are reported in earnings.
For a derivative instrument to qualify for cash flow hedge accounting: - the relationship between the derivative instrument and the forecasted transaction being hedged must be formally documented at inception, - the derivative instrument must be highly effective in offsetting the hedged transaction's cash flows, and - the forecasted transaction being hedged must be probable.
the relationship between the derivative instrument and the forecasted transaction being hedged must be formally documented at inception,
the derivative instrument must be highly effective in offsetting the hedged transaction’s cash flows, and
the forecasted transaction being hedged must be probable.
If a derivative qualifies for cash flow hedge accounting treatment and gains or losses are recorded in AOCL, those gains or losses will be reclassified into earnings in the same period or periods the hedged forecasted transaction affects earnings. If a cash flow hedge is terminated early because it is determined that the forecasted transaction will not occur, any gain or loss recorded in AOCL at that date is recognized immediately in earnings. If a cash flow hedge is terminated early for other economic reasons, any gain or loss as of the termination date is deferred and then reclassified to earnings when the forecasted transaction affects earnings. The ineffective portion, if any, of all hedges is recognized in earnings.

CMS Energy Corporation
To determine the fair value of our derivatives, we use information from external sources (i.e., quoted market prices and third-partythird party valuations), if available. For certain contracts, this information is not available and we use mathematical valuation models to value our derivatives. These models require various inputs and assumptions, including commodity market prices and volatilities, as well as interest rates and contract maturity dates. The cash returns we actually realize on these contracts may vary, either positively or negatively, from the results that we estimate using these models. As part of valuing our derivatives at market, we maintain reserves, if necessary, for credit risks arising from the financial condition of our counterparties.
The majority of our commodity purchase and sale contracts are not subject to derivative accounting under SFAS No. 133 because: - they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas), - they qualify for the normal purchases and sales exception, or - there is not an active market for the commodity.
they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas),
they qualify for the normal purchases and sales exception, or
there is not an active market for the commodity.
Our coal purchase contracts are not derivatives because there is not an active market for the coal we purchase. If an active market for coal develops in the future, some of these contracts may qualify as derivatives and the resulting mark-to-market impact on earnings could be material.
Derivative accounting is required for certain contracts used to limit our exposure to interest rate risk, commodity price risk, and foreign exchange risk. The following table summarizes our derivative instruments: CMS-62 CMS Energy Corporation

TheAt December 31, 2006, the fair value of derivative contracts associated with our equity investments iswas included in Investments - Enterprises on our Consolidated Balance Sheets.
Interest Rate Risk Contracts:In June 2007, we announced a tender offer to repurchase certain of our senior notes. Under the terms of the offer, the holders of those notes had until July 2, 2007 to tender their notes in return for an agreed-upon tender price. This debt tender offer was a derivative instrument and changes in its fair value were recorded in earnings until the offer was settled on July 3, 2007.
CMS ERM CONTRACTS: Contracts:CMS ERM enters into and owns energy contracts that support CMS Energy'sEnergy’s ongoing operations. CMS ERM holds certain contracts for the future purchase and sale of natural gas that will result in physical delivery of the commodity at contractual prices. These forward contracts are generally long-term in nature and are classified as non-trading. CMS ERM also uses various financial instruments, including swaps, options, and futures, to manage commodity price risks associated with its forward purchase and sale contracts and with generation assets owned by CMS Energy or its subsidiaries. These financial contracts are classified as trading activities.
In accordance with SFAS No. 133, non-trading and trading contracts that qualify as derivatives are recorded at fair value on our Consolidated Balance Sheets. The resulting assets and liabilities are marked to market each quarter, and changes in fair value are recorded in earnings as a component of Operating Revenue. For trading contracts, these gains and losses are recorded net in accordance with EITF Issue No. 02-03. Contracts that do not meet the definition of a derivative are accounted for as executory contracts (that is, on an accrual basis). DERIVATIVE CONTRACTS ASSOCIATED WITH EQUITY INVESTMENTS: At March 31,
Derivative Contracts Associated with Equity Investments:In May 2007, somewe sold our ownership interest in businesses in the Middle East, Africa, and India. Certain of our equity method investees, specifically Taweelah, Shuweihat, Jorf Lasfar, and Jubail,these businesses held: -
interest rate contracts that hedged the risk associated with variable-rate debt, and
foreign exchange contracts that hedged the foreign currency risk associated with payments to be made under operating and maintenance service agreements.

Wesale, we recorded our proportionate share of the change in fair value of these contracts in AOCL if the contracts qualified for cash flow hedge accounting; otherwise, we recorded our share in Earnings from Equity Method Investees.
At March 31, 2007, there was no ineffectiveness associated with anythe date of the contracts that qualify for cash flow hedge accounting. In May 2007, we sold our ownership interest in businesses in the Middle East, Africa, and India, including Taweelah, Shuweihat, CMS-63 CMS Energy Corporation Jorf Lasfar, and Jubail. As a result of that sale, we will no longer recognize gains or losses related to changes in the fair value of the derivative contracts held by these equity method investees. At March 31, 2007, we had accumulated a cumulative net loss of $14$13 million, net of tax, in AOCL representing our proportionate share of mark-to-market gains and losses from cash flow hedges held by the equity method investees. At the date we closedAfter the sale, we reclassified this amount adjusted for any additional changes in fair value, was reclassified and recognized it in earnings as parta reduction of the sale. This amount comprisedgain on the total amount we had recorded in AOCL related to derivative instruments. Any changes in the fair value of these contracts recognized before the closing did not affect the sales price of our interest in these equity method investees.sale. For additional details on the sale of our interest in these equity method investees, see Note 2, Asset Sales, Discontinued Operations and Impairment Charges. FOREIGN EXCHANGE DERIVATIVES: In the past, we have used forward exchange and option contracts to hedge the value of investments in foreign operations. These contracts limited the risk from currency exchange rate movements because gains and losses on such contracts offset losses and gains, respectively, on the hedged investments. At March 31, 2007, we had no outstanding foreign exchange contracts. However, the impact of previous hedges on our investments in foreign operations is reflected in AOCL as a component of the foreign currency translation adjustment on our Consolidated Balance Sheets. Gains or losses from the settlement of these hedges are maintained in the foreign currency translation adjustment until we sell or liquidate the hedged investments. At March 31, 2007, our total foreign currency translation adjustment was a net loss of $169 million, which included a net hedging loss of $22 million, net of tax, related to the settlement of these contracts. CREDIT RISK:
Credit Risk: Our swaps, options, and forward contracts contain credit risk, which is the risk that counterparties will fail to perform their contractual obligations. We reduce this risk through established credit policies. For each counterparty, we assess credit quality by using credit ratings, financial condition, and other available information. We then establish a credit limit for each counterparty based upon our evaluation of credit quality. We monitor the degree to which we are exposed to potential loss

under each contract and take remedial action, if necessary.
CMS ERM enters into contracts primarily with companies in the electric and gas industry. This industry concentration may have an impact on our exposure to credit risk, either positively or negatively, based on how these counterparties are affected by similar changes in economic conditions, the weather, or other conditions. CMS ERM typically uses industry-standard agreements that allow for netting positive and negative exposures associated with the same counterparty, thereby reducing exposure. These contracts also typically provide for the parties to demand adequate assurance of future performance when there are reasonable grounds for doing so.
The following table illustrates our exposure to potential losses at March 31,June 30, 2007, if each counterparty within this industry concentration failed to perform its contractual obligations. This table includes contracts accounted for as financial instruments. It does not include trade accounts receivable, derivative contracts that qualify for the normal purchases and sales exception under SFAS No. 133, or other contracts that are not accounted for as derivatives.

SFAS No. 158, Employers'Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R):In September 2006, the FASB issued SFAS No. 158. Phase one of this standard required us to recognize the funded status of our defined benefit postretirement plans on our Consolidated Balance Sheets at December 31, 2006. Phase one was implemented in December 2006. Phase two of this standard requires that we change our plan measurement date from November 30 to December 31, effective December 31, 2008. We do not believe that implementation of phase two of this standard will have a material effect on our consolidated financial statements. We expect to adopt the measurement date provisions of SFAS No. 158 in 2008.

As a result of the implementation of FIN 48, we have identified additional uncertain tax benefits of $11 million as of January 1, 2007. Included in this amount is an increase in our valuation allowance of $100 million, decreases to tax reserves of $61 million and a decrease to deferred tax liabilities of $28 million. In addition, our equity method investment, Jorf Lasfar, in which we held a 50 percent interest, CMS-66 CMS Energy Corporation identified $26 million of uncertain tax benefits in its adoption of FIN 48 for U.S. GAAP purposes. We have reflected our share of this amount, $13 million, as a reduction to our beginning retained earnings balance and in our investment in the subsidiary. Thus, our beginning retained earnings was reduced by $24 million as a result of the adoption of FIN 48.
CMS Energy and its subsidiaries file a consolidated U.S. federal income tax return as well as unitary and combined income tax returns in several states. CMS Energy and its subsidiaries also file separate company income tax returns in several states. The only significant state tax paid by CMS Energy is in Michigan. However, since the Michigan Single Business Tax is not an income tax, it is not part of the FIN 48 analysis. For the U.S. federal income tax return, CMS Energy completed examinations by federal taxing authorities for its taxable years prior to 2002. The federal income tax returns for the years 2002 through 2005 are open under the statute of limitations.
We have reflected a net interest liability of $3 million related to our uncertain income tax positions on our Consolidated Balance Sheets as of January 1, 2007. We have not accrued any penalties with respect to uncertain tax benefits. We recognize accrued interest and penalties, where applicable, related to uncertain tax benefits as part of income tax expense.

CMS-71


CMS Energy Corporation
As of the date of adoption of FIN 48, we had valuation allowances against certain U.S. and foreign deferred tax assets totaling $216 million and other uncertain tax positions of $31 million, resulting in total unrecognized benefits of $247 million. Of this amount, $217 million would result in a decrease in our effective tax rate, if recognized. We released $81 million of our valuation allowance in the first quarter of 2007, reducing our effective tax rate, due to the anticipated sales of our foreign investments, as reflected in our effectiveinvestments. During the second quarter we reduced deferred tax rate reconciliation. Therefore, remaining uncertain tax benefits that would reduce our effective tax rate beyond this quarter are $136 million.assets and related valuation allowances attributable to sold foreign assets by $63 million each. This reduction had no income impact. As we continue to market our foreign investments, it is reasonably possible that additional valuation allowance adjustments could be made. We are not in a position to estimate any additional adjustment at this date, other than to state that we have no expectation of reversing any of the $86 million valuation allowance attributable to the inflation indexing of our Venezuelan investment. We are not expecting any other material changes to our uncertain tax positionsmade over the next 12 months.

U.S. income taxes arewere not recorded on the undistributed earnings of foreign subsidiaries that havehad been or arewere intended to be reinvested indefinitely. Upon distribution, those earnings maywould likely be subject to both U.S. income taxes (adjusted for foreign tax credits or deductions) and withholding taxes payable to various foreign countries. During the first quarter of 2007, we announced we had signed agreements or plans to sell substantially all of our foreign assets or subsidiaries. These anticipated sales resulted in the recognition in 2007 of $63$71 million of U.S. income tax expense associated with the change in our determination of our permanent reinvestment of these undistributed earnings, with $43$46 million of this amount reflected in income from continuing operations and $20$25 million in discontinued operations. With this recognition, U.S. tax has now been provided on all foreign undistributed earnings.

Fair value, to the extent possible, should include a market risk premium for unforeseeable circumstances. No market risk premium was included in our ARO fair value estimate

since a reasonable estimate could not be made. If a five percent market risk premium were assumed, our ARO liability would increase by $25$5 million.
If a reasonable estimate of fair value cannot be made in the period in which the ARO is incurred, such as for assets with indeterminate lives, the liability is to be recognized when a reasonable estimate of fair value can be made. Generally, electric and gas transmission and distribution assets have indeterminate lives. Retirement cash flows cannot be determined and there is a low probability of a retirement date. Therefore, no liability has been recorded for these assets or associated obligations related to potential future abandonment. Also, no liability has been recorded for assets that have insignificant cumulative disposal costs, such as substation batteries. The measurement of the ARO liabilities
FASB Interpretation No. 47,Accounting for Palisades and Big Rock include use of decommissioning studies that largely utilize third-party cost estimates. CMS-68 CMS Energy Corporation FASB INTERPRETATION NO. 47, ACCOUNTING FOR CONDITIONAL ASSET RETIREMENT OBLIGATIONS: Conditional Asset Retirement Obligations:This Interpretation clarified the term "conditional“conditional asset retirement obligation"obligation” as used in SFAS No. 143. The term refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event. We determined that abatement of asbestos included in our plant investments qualifies as a conditional ARO, as defined by FIN 47.

In October 2004, the MPSC initiated a generic proceeding to review SFAS No. 143, FERC Order No. 631, Accounting, Financial Reporting, and Rate Filing Requirements for Asset Retirement Obligations, and related accounting and ratemaking issues for MPSC-jurisdictional electric and gas utilities. In June 2007, the MPSC issued an order that requires:
the MPSC Staff to advise the MPSC whether there are any FERC accounts, rules or procedures that should be adopted by reference or changed, and
the use of a revised calculation for cost of removal estimates derived from applying SFAS No. 143, which includes the use of standard retirement units.
We will also be required to file a new gas depreciation study by August 2006,1, 2008, using 2007 removal costs as the ALJ issuedbasis for the calculation and a Proposalnew electric depreciation study by August 3, 2009, using 2008 removal costs as the basis for Decision that included recommendations that the MPSC: - - adopt SFAS No. 143 and FERC Order No. 631 for accounting purposes but not for ratemaking purposes, - - consider adopting standardized retirement units for certain accounts, - - consider revising the method of determining cost of removal, and - - withhold approving blanket regulatory asset and regulatory liability accounting treatment related to ARO, stating that modifications to the MPSC's Uniform System of Accounts should precede any such accounting approval. We consider the proceeding a clarification of accounting and reporting issues that relate to all Michigan utilities. We cannot predict the outcome of the proceeding. calculation.

Consumers Energy Company CONSUMERS ENERGY COMPANY MANAGEMENT'S DISCUSSION AND ANALYSIS
Consumers Energy Company
Management’s Discussion and Analysis
In this MD&A, Consumers Energy, which includes Consumers Energy Company and all of its subsidiaries, is at times referred to in the first person as "we," "our"“we,” “our” or "us."“us.” This MD&A has been prepared in accordance with the instructions to Form 10-Q and Item 303 of Regulation S-K. This MD&A should be read in conjunction with the MD&A contained in Consumers Energy'sEnergy’s Form 10-K for the year ended December 31, 2006. EXECUTIVE OVERVIEW Consumers, a subsidiary of CMS Energy, a holding company, is a combination electric
Forward-looking statements and gas utility company serving Michigan's Lower Peninsula. Our customer base includes a mix of residential, commercial, and diversified industrial customers. We manage our business by the nature of services each provides and operate principally in two business segments: electric utility and gas utility. Our electric utility operations include the generation, purchase, distribution, and sale of electricity. Our gas utility operations include the purchase, transportation, storage, distribution, and sale of natural gas. We earn our revenue and generate cash from operations by providing electric and natural gas utility services, electric power generation, gas distribution, transmission, and storage, and other energy related services. Our businesses are affected primarily by: - weather, especially during the normal heating and cooling seasons, - economic conditions, - regulation and regulatory issues, - energy commodity prices, - interest rates, and - our debt credit rating. During the past several years, our business strategy has involved improving our consolidated balance sheet and maintaining focus on our core strength: utility operations and service. In April 2007, we sold Palisades to Entergy for $380 million. The final purchase price was subject to various closing adjustments resulting in us receiving $361 million. We also paid Entergy $30 million to assume ownership and responsibility for the Big Rock Independent Spent Fuel Storage Installation (ISFSI). We entered into a 15-year power purchase agreement with Entergy for 100 percent of the plant's current electric output. The sale resulted in an immediate improvement in our cash flow, a reduction in our nuclear operating and decommissioning risk, and an improvement in our financial flexibility to support other utility investments. The MPSC order approving the transaction requires that $255 million be credited to our retail customers through refunds applied over the remainder of 2007 and 2008. Natural gas prices are volatile and have an impact on working capital and cash flow. Although our natural gas costs are recoverable from our utility customers, higher-priced natural gas stored as inventory requires additional liquidity due to the lag in cost recovery. CE-1 Consumers Energy Company In the future, we will continue to focus on: - investing in our utility system to enable us to meet our customer commitments, comply with increasing environmental performance standards, and maintain adequate supply and capacity, - growing earnings while controlling operating costs, and - managing cash flow issues. As we execute our strategy, we will need to overcome a sluggish Michigan economy that has been hampered by negative developments in Michigan's automotive industry and limited growth in the non-automotive sectors of the state's economy. The return of ROA customer load has offset some of these negative effects. At March 31, 2007, alternative electric suppliers were providing 283 MW of generation service to ROA customers. This is 3 percent of our total distribution load and represents a decrease of 19 percent of ROA load compared to March 31, 2006. FORWARD-LOOKING STATEMENTS AND INFORMATION information

Executive Overview
Consumers, a subsidiary of CMS Energy, a holding company, is a combination electric and gas utility company serving Michigan’s Lower Peninsula. Our customer base includes a mix of residential, commercial, and diversified industrial customers.
We manage our business by the nature of services each provides and operate principally in two business segments: electric utility and gas utility. Our electric utility operations include the generation, purchase, distribution, and sale of electricity. Our gas utility operations include the purchase, transportation, storage, distribution, and sale of natural gas.
We earn our revenue and generate cash from operations by providing electric and natural gas utility services, electric power generation, gas distribution, transmission, and storage, and other energy related services. Our businesses are affected primarily by:
weather, especially during the normal heating and cooling seasons,
economic conditions,
regulation and regulatory issues,
energy commodity prices,
interest rates, and
our debt credit rating.
During the past several years, our business strategy has involved improving our consolidated balance sheet and maintaining focus on our core strength: utility operations and service.
In April 2007, we sold Palisades to Entergy for $380 million. The final purchase price is subject to various closing adjustments resulting in us receiving $364 million as of June 30, 2007. We also paid Entergy $30 million to assume ownership and responsibility for the Big Rock ISFSI. We entered into a 15-year power purchase agreement with Entergy for 100 percent of the plant’s current electric output. The sale resulted in an immediate improvement in our cash flow, a reduction in our nuclear operating and decommissioning risk, and an improvement in our financial flexibility to support other utility investments. The MPSC order approving the transaction requires that we refund $255 million to our retail customers through credits applied from June 2007 through December 2008. There are additional excess sales proceeds and decommissioning fund balances of $127 million above the amount in the MPSC order. The distribution of these additional amounts has not yet been addressed by the MPSC.

CE - 3


Consumers Energy Company RESULTS OF OPERATIONS
After September 15, 2007, we expect to claim relief under the regulatory-out provision in the MCV PPA, thereby limiting our capacity and fixed energy payments to the MCV Partnership to the amounts that we collect from our customers. If we are successful in exercising the regulatory-out provision, the MCV Partnership may, under certain circumstances, have the right to terminate or reduce the amount of capacity sold under the MCV PPA, which could affect our need to build or purchase additional generating capacity.
We introduced our Balanced Energy Initiative, a comprehensive plan to meet customer energy needs over the next 20 years, in May 2007. The plan, as filed with the MPSC, is designed to meet the growing customer demand for electricity with energy efficiency, demand management, expanding the use of renewable energy, and developing new power plants to complement existing generating sources.
In May 2007, we entered an agreement to buy a 946 MW natural gas-fired power plant located in Zeeland, Michigan with Broadway Gen Funding LLC, an affiliate of LS Power Group, for $517 million. The purchase is subject to approvals from the MPSC and other regulatory bodies and is expected to close in early 2008.
In the future, we will continue to focus on:
investing in our utility system to enable us to meet our customer commitments, comply with increasing environmental performance standards, and maintain adequate supply and capacity,
growing earnings while controlling operating costs,
managing cash flow issues, and
principles of safe, efficient operations, customer value, fair and timely regulation, and consistent financial performance.
As we execute our strategy, we will need to overcome a sluggish Michigan economy that has been hampered by negative developments in Michigan’s automotive industry and limited growth in the non-automotive sectors of the state’s economy. The return of ROA customer load has offset some of these negative effects. At June 30, 2007, alternative electric suppliers were providing 302 MW of generation service to ROA customers. This is 3 percent of our total distribution load and represents a decrease of 3 percent of ROA load compared to June 30, 2006.

The increase also reflects higher net income from our electric and gas utilities due to higher, weather-driven sales caused by favorable weather compared to 2006, and a gas rate increase authorized in November 2006. Partially offsetting these gains was a decrease in electric net income due to the sale of Palisades in April 2007. As a result of the sale of Palisades, electric revenue related to the recovery of Palisades and Big Rock costs has been used to offset costs incurred under our power purchase agreement with Entergy.

In the first quarter of 2006, we started collecting a surcharge that the MPSC authorized under Section 10d(4) of the Customer Choice Act. Due to timing considerations, thisThis surcharge increased electric delivery revenue by $5$3 million infor the first quarter ofthree months ended June 30, 2007 and $8 million for the six months ended June 30, 2007 versus the same periods in 2006. The increase was primarily due to higher surcharge factors in 2007 versus the same period in 2006.
The Customer Choice Act allows all of our electric customers to buy electric generation service from us or from an alternative electric supplier. At March 31,June 30, 2007, alternative electric suppliers were providing 283302 MW of generation service to ROA customers. This amount represents a decrease of 193 percent compared to March 31,June 30, 2006. The return of former ROA customers to full-service rates increased electric delivery revenue less than $1 million for the three months ended June 30, 2007 and $2 million infor the first quarter ofsix months ended June 30, 2007 versus the same periods in 2006.

Consumers Energy Company
Power supply costs and related revenue:For the three months and six months ended June 30, 2007, PSCR revenue decreased by $12 million versus 2006. OTHER OPERATING EXPENSES, OTHER INCOME AND NON-COMMODITY REVENUE: InThe decrease primarily reflects a reduction in amounts to be recovered under the first quarter ofPSCR mechanism.
Other operating expenses, other income and non-commodity revenue:For the three months ended June 30, 2007, other operating expenses decreased $1$48 million, other income increased $6$10 million, and non-commodity revenue increased $2decreased $3 million versus 2006. For the six months ended June 30, 2007, other operating expenses decreased $49 million, other income increased $16 million, and non-commodity revenue decreased $1 million versus 2006.
The decrease in other operating expenses was primarily due to lower operating and maintenance expense, including reductions to certain workers'workers’ compensation and injuries and damages expense. These decreases were offset partially by higher depreciation amortization, and overheadamortization expense. Operating and maintenance expense decreased primarily due to the absence, in 2007, of costs incurred in 2006 related to a planned refueling outage at our Palisades, nuclear plant, and lower overhead, line maintenance, and storm restoration costs. Also contributing to the decrease was the sale of Palisades in April 2007. Depreciation and amortization expense increased due to higher non-nuclear plant in service and greater amortization of certain regulatory assets. Overhead expense increased primarily due to costs related to our voluntary separation program and costs associated with our utility reorganization. The
For the three months ended June 30, 2007, the increase in other income was primarily due to higher interest income. For the six months ended June 30, 2007, the increase in other income was primarily due to higher interest income and higher income associated with our Section 10d(4) Regulatory Asset. ThisThe increase on our Section 10d(4) Regulatory Asset reflects the absence, in 2007, of the impact of the MPSC'sMPSC’s final order in CE-6 Consumers Energy Company this case. The increase in non-commodity revenue was primarily due to higher revenue from customer late payment fees. GENERAL TAXES: In
General taxes:For the first quarter ofthree months ended June 30, 2007, general tax expense increased primarily due to higher property tax and sales and use tax expense, offset partially by lower MSBT expense. For the six months ended June 30, 2007, general tax expense versus 2006. INTEREST CHARGES: Inincreased due to higher property tax and sales and use tax expense.
Interest charges:For the first quarter ofthree months and six months ended June 30, 2007, interest charges decreasedincreased primarily due to lower average debt levels and lower interest expense associated with potential customer refundsamounts to be refunded to customers as a result of the sale of Palisades. The MPSC order approving the Palisades power purchase agreement with Entergy directed us to record interest on the unrefunded balance.
Income taxes:For the three months ended June 30, 2007, income taxes increased versus 2006. INCOME TAXES: In2006 primarily due to the first quarterabsence, in 2007, of the resolution of an IRS income tax audit which resulted in an income tax benefit primarily for the utilization or restoration of income tax credits. For the six months ended June 30, 2007, income taxes increased primarily due to higher earnings by the electric utility versus 2006. Partially offsetting this increase is the absence, in 2007, of adjustments to certain deferred tax balances. For additional details, see Note 7, Income Taxes.

InThe decrease is due to the absence of a tax benefit, in 2007, associated with the resolution of an IRS income tax audit. Primarily offsetting this decrease was the sale, in late 2006, we soldof our ownership interest in the MCV Partnership. The change in earnings reflects the absence, in 2007, of a $57$6 million loss related to our ownership interest in the MCV Partnership.

Critical Accounting Policies
The following accounting policies are important to an understanding of our results of operations and financial condition and should be considered an integral part of our MD&A. For additional accounting policies, see Note 1, Corporate Structure and Accounting Policies. USE OF ESTIMATES AND ASSUMPTIONS
Use of Estimates and Assumptions
We use estimates and assumptions in preparing our consolidated financial statements that may affect reported amounts and disclosures. We use accounting estimates for asset valuations, depreciation, amortization, financial and derivative instruments, employee benefits, and contingencies. For example, we estimate the rate of return on plan assets and the cost of future health-care benefits to determine our annual pension and other postretirement benefit costs. Actual results may differ from estimated results due to factors such as changes in the regulatory environment, competition, regulatory decisions, and lawsuits. CONTINGENCIES:
Contingencies:We are involved in various regulatory and legal proceedings that arise in the ordinary course of our business. We record a liability for contingencies based upon our assessment that a loss is probable and the amount of loss can be reasonably estimated. We use the principles in SFAS No. 5 when recording estimated liabilities for contingencies. We consider many factors in making these assessments, including the history and specifics of each matter. We discuss significant contingencies in the "Outlook"“Outlook” section included in this MD&A. CE-8

Consumers Energy Company ACCOUNTING FOR FINANCIAL AND DERIVATIVE INSTRUMENTS AND MARKET RISK INFORMATION FINANCIAL INSTRUMENTS:
Accounting for Financial and Derivative Instruments and Market Risk Information
Financial Instruments:Debt and equity securities classified as available-for-sale are reported at fair value determined from quoted market prices. Debt and equity securities classified as held-to-maturity are reported at cost. Unrealized gains or losses resulting from changes in fair value of certain available-for-sale debt and equity securities are reported, net of tax, in equity as part of AOCI. Unrealized gains or losses are excluded from earnings unless the related changes in fair value are determined to be other than temporary. Unrealized gains or losses on our nuclear decommissioning investments are reflected as regulatory liabilities on our Consolidated Balance Sheets. Realized gains or losses would not affect our consolidated earnings or cash flows. DERIVATIVE INSTRUMENTS: earnings.
Derivative Instruments:We account for derivative instruments in accordance with SFAS No. 133. Since the year ended December 31, 2006, there have been no significant changes in the amount or types of derivatives that we hold or to how we account for derivatives. For additional details on our derivatives, see Note 4,5, Financial and Derivative Instruments.
To determine the fair value of our derivatives, we use information from external sources (i.e., quoted market prices and third-partythird party valuations), if available. For certain contracts, this information is not available and we use mathematical valuation models to value our derivatives. These models require various inputs and assumptions, including commodity market prices and volatilities, as well as interest rates and contract maturity dates. Changes in forward prices or volatilities could significantly change the calculated fair value of our derivative contracts. The cash returns we actually realize on these contracts may vary, either positively or negatively, from the results that we estimate using these models. As part of valuing our derivatives at market, we maintain reserves, if necessary, for credit risks arising from the financial condition of our counterparties. MARKET RISK INFORMATION:
Market Risk Information:The following is an update of our risk sensitivities since December 31, 2006. These sensitivities indicate the potential loss in fair value, cash flows, or future earnings from our financial instruments, including our derivative contracts, assuming a hypothetical adverse change in market rates or prices of 10 percent. Changes in excess of the amounts shown in the sensitivity analyses could occur if changes in market rates or prices exceed the 10 percent shift used for the analyses.

We maintained trust funds, as required by the NRC, for the purpose of funding certain costs of nuclear plant decommissioning through April 2007, the date of the sale of Palisades. These funds were invested primarily in equity securities, fixed-rate, fixed-income debt securities, and cash and cash equivalents, and have been recorded at fair value on our Consolidated Balance Sheets. These investments were exposed to price fluctuations in equity markets and changes in interest rates. Because the accounting for nuclear plant decommissioning recognized that costs were recovered through our electric rates, fluctuations in equity prices or interest rates did not affect our consolidated earnings or cash flows.

During the summer months, we purchase natural gas and store it for resale primarily during the winter heating season. Although our prudent natural gas costs are recoverable from our customers, the amount paid for natural gas stored as inventory requires additional liquidity due to the lag in cost recovery. We have credit agreements with our commodity suppliers containing terms that can result in margin calls. While we currently have no outstanding margin calls associated with our natural gas purchases, they may be required if agency ratings are lowered or if market conditions become unfavorable relative to our obligations to those parties.
Our current financial plan includes controlling operating expenses and capital expenditures and evaluating market conditions for financing opportunities, if needed.

This increase was primarily dueIn addition to increased earnings, the timing of accounts payable,operating cash flow increased usage of gas inventory in storage, anddue to the absence in 2007 of tax payments made to the MCV Partnership gas supplier funds on deposit, partially offset byparent related to the timing of accounts receivable. We experienced colder weather in the first quarter of 2007 versus 2006. The timing of payments for increased natural gas purchases to meet customer demand in the first quarter of 2007, coupled with the absence ofIRS income tax audit, payments for higher priced gas made during the first quarterpart of 2006, increasedand the MCV Partnership gas supplier funds on deposit. Also increasing our operating cash flow. A mildflow was our increased usage of gas already in storage during 2007, as the milder winter in 2006 allowed us to accumulate more gas in our underground storage facilities. The increased usage of gas already in storage during the first quarter of 2007 also increased our operating cash flow. These increases were reduced partially by the timing of our collection of increased billings in the first quarter of 2007 due to recent regulatory actions and weather-driven demand. INVESTING ACTIVITIES: demand and the absence in 2007 of additional payables to the parent related to the IRS income tax audit.

Outlook
CORPORATE OUTLOOK
Our business strategy will focus on investing in our utility system to enable us to meet our customer commitments, comply with increasing environmental performance standards, and maintain adequate supply and capacity. In the first quarter of 2007, we completed a reorganization of the company that we announced in November 2006. The reorganization improves operating efficiency, reliability, and customer service.
ELECTRIC BUSINESS OUTLOOK GROWTH:
Growth:In 2007, we expect electric deliveries to grow about one-half of one percent compared to 2006 levels. The outlook for 2007 assumes a small decline in industrial economic activity and normal weather conditions throughout the remainder of the year.
Over the next five years, we expect electric deliveries to grow at an average rate of about 1.5 percent per year. This outlook assumes a modestly growing customer base and a stabilizing Michigan economy after 2007. This growth rate includes both full-service sales and delivery service to customers who choose to buy generation service from an alternative electric supplier, but excludes transactions with other wholesale market participants and other electric utilities. This growth rate reflects a long-range expected trend of growth. Growth from year to year may vary from this trend due to customer response to the following:
energy conservation measures,
fluctuations in weather conditions, and
changes in economic conditions, including utilization and expansion or contraction of manufacturing facilities.

CE - energy conservation measures, - fluctuations in weather conditions, and - changes in economic conditions, including utilization and expansion or contraction of manufacturing facilities. ELECTRIC CUSTOMER REVENUE OUTLOOK: Our electric utility customer base includes a mix of residential, commercial, and diversified industrial customers. In 2006, Michigan's14


Consumers Energy Company
Electric Customer Revenue Outlook:Michigan’s economy has been hampered by automotive industry experienced manufacturing facility closures and restructurings. OurThe Michigan economy has also had limited growth in the non-automotive sector. Although our electric utility results are not dependent upon a single customer, or even a few customers, and customers in the automotive sector represented five percent of our total 2006 electric revenue.
Electric Reserve Margin:We cannot predict the impact of current or possible future restructuring plans or possible future actions by our industrial customers. ELECTRIC RESERVE MARGIN: We are planning forhave a reserve margin of approximately 11 percent for summer 2007, or supply resources equal to 111 percent of projected firm summer peak load. Of the 2007 supply resources target of 111 percent, we expect 96 percent to comecomes from our electric generating plants and long-term power purchase contracts, and 15 percent to comecomes from other contractual arrangements. Our 15-year power purchase agreement with Entergy for 100 percent of the Palisades facility'sfacility’s current electric output will offset the reduction in the owned capacity represented by the sale of the Palisades facility in April 2007. We have purchased capacity and energy contracts covering the reserve margin requirements for 2007 and covering partially the estimated reserve margin requirements for 20072008 through 2010. As a result, we recognized an asset of $62 million for unexpired seasonal capacity and energy contracts at March 31, 2007. CE-13 Consumers Energy Company
After September 15, 2007, we expect to exercise the regulatory outregulatory-out provision in the MCV PPA, resulting in a reduction in the amount paid to the MCV Partnership to equal the amount we are allowed to recover in the rate charged to customers. If we are successful in exercising this provision, the MCV Partnership may, under certain circumstances, have the right to terminate the MCV PPA, which could affect our reserve margin status. The MCV PPA represents 13 percent of our 2007 supply resources target. ELECTRIC UTILITY PLANT OUTAGE: In September 2006, we removed from service unit three of the J.H. Campbell electric generating plant, representing 765 MW of our capacity. The scheduled outage was for installation of equipment necessary to comply with environmental standards. We expected the unit to return to service in March 2007. However, the outage extended to May 1, 2007 due to unanticipated delays in construction due to labor shortages, the collapse of an outdoor crane on unit three and problems with a major generator component that was refurbished by the original equipment manufacturer. The MPSC allows for the recovery of reasonable and prudent replacement power costs. ELECTRIC TRANSMISSION EXPENSES: resources.
Electric Transmission Expenses:METC, which provides electric transmission service to us, increased substantially the transmission rates it charged us in 2006. The revenue collected by METC under those rates is subject to refund pending a FERC ruling. In January 2007, the parties filed a settlement agreement with the FERC. This settlement, if approved by the FERC, will result in a refund of 2006 transmission charges of $18 million and a corresponding reduction of our power supply costs. For additional details on power supply costs, see Note 2,3, Contingencies, "Electric“Electric Rate Matters - Power Supply Costs." 21ST CENTURY ELECTRIC ENERGY PLAN:
21st Century Electric Energy Plan:In January 2007, the chairman of the MPSC proposed three major policy initiatives to the governor of Michigan. The initiatives involve the use of more renewable energy resources by all load-serving entities such as Consumers, the creation of an energy efficiency program, and a procedure for reviewing proposals to construct new generation facilities. The January proposal indicated that Michigan needs new base-load capacity by 2015 and recommends measures to make it easier to predict customer demand and revenues. The proposed initiatives will require changes to current legislation. We will continue to participate as the MPSC, legislature, and other stakeholders address future electric resource needs. BALANCED ENERGY INITIATIVE:
Balanced Energy Initiative:In May 2007, we filed a "Balanced“Balanced Energy Initiative"Initiative” with the MPSC providing a comprehensive energy resource plan to meet our projected short-term and long-term electric power requirements. The plan is responsive to the 21st Century Electric Energy Plan and assumes that Michigan will implement a state-wide energy efficiency program and a renewable energy portfolio standard. The filing requests the MPSC to rule that the Balanced Energy Initiative represents a reasonable and prudent plan for the acquisition of necessary electric utility resources.
As acknowledged in the 21st Century Electric Energy Plan, implementation of the Balanced Energy Initiative will require legislative repeal or significant reform of the Michigan customer choice law.Customer Choice Act. In addition, we endorse the 21st Century Electric Energy Plan recommendation to adopt a new, up-front certification policy for major power plant investments. Our filing requests the MPSC to find that the addition of 500 MW of gas-fired combined cycle generating capacity is reasonable and prudent. This addition could be in the form of the construction of a new gas-fired generating plant to begin service in 2011, or in the form of a purchase of an existing gas-fired facility. The filing also

Consumers Energy Company
recommends construction of a new 750 MW clean coal generating facility on an existing Consumers site to begin operation in 2015. Ownership of 250 MW of the total capacity is assumed to be allocated to municipal entities or other interested parties, resulting in 500 MW dedicated to us. PROPOSED RENEWABLE ENERGY LEGISLATION: our use.
Proposed Power Plant Purchase:In May 2007, we reached an agreement with Broadway Gen Funding LLC, an affiliate of LS Power Group, to buy a 946 MW gas-fired power plant located in Zeeland, Michigan for $517 million. The power plant will help meet the growing energy needs of our customers. We expect to close on the purchase in early 2008, subject to MPSC and other regulatory approvals and other closing conditions.
Proposed Renewable Energy Legislation:There are various bills introduced into in the U.S. Congress and the Michigan legislature relating to mandatory renewable energy standards. If enacted, these bills generally would require electric utilities to acquire a certain percentage of their power from renewable sources or otherwise pay fees or purchase allowances in lieu of having the resources. We cannot predict whether any such bill will be enacted or in what form. CE-14 Consumers Energy Company
ELECTRIC BUSINESS UNCERTAINTIES
Several electric business trends or uncertainties may affect our financial condition and future results of operations. These trends or uncertainties have, or we reasonably expect could have, a material impact on revenues or income from continuing electric operations. ELECTRIC ENVIRONMENTAL ESTIMATES:
Electric Environmental Estimates:Our operations are subject to environmental laws and regulations. Costs to operate our facilities in compliance with these laws and regulations generally have been recovered in customer rates.
Clean Air Act:Compliance with the federal Clean Air Act and resulting regulations continues to be a significant focus for us. The Nitrogen Oxide State Implementation Plan requires significant reductions in nitrogen oxide emissions. To comply with the regulations, we expect to incur capital expenditures totaling $835 million. From 1998 to present, we have incurred $782 million in capital expenditures to comply with the federal Clean Air Act and resulting regulations and anticipate that the remaining $53 million of capital expenditures will be made in 2007 through 2011. These expenditures include installing selective catalytic reduction control technology on four of our coal-fired electric generating units. The key assumptions in the capital expenditure estimate include: - construction commodity prices, especially construction material and labor, - project completion schedules, - cost escalation factor used to estimate future years' costs, and - an AFUDC capitalization rate.
construction commodity prices, especially construction material and labor,
project completion schedules,
cost escalation factor used to estimate future years’ costs, and
an AFUDC capitalization rate.
Our current capital cost estimates include an escalation rate of 2.6 percent and an AFUDC capitalization rate of 7.8 percent. From 1998 to present, we have incurred $760 million in capital expenditures to comply with the federal Clean Air Act and resulting regulations and anticipate that the remaining $75 million of capital expenditures will be made in 2007 through 2011.
In addition to modifying coal-fired electric generating plants, our compliance plan includes the use of nitrogen oxide emission allowances until all of the control equipment is operational in 2011. The nitrogen oxide emission allowance annual expense is projected to be $3$2 million per year, which we expect to recover from our customers through the PSCR process. The projected annual expense is based on market price forecasts and forecasts of regulatory provisions, known as progressive flow control, that restrict the usage in any given year of allowances banked from previous years. The allowances and their cost are accounted for as inventory. The allowance inventory is expensed at the rolling average cost as the electric generating plants emit nitrogen oxide.

Consumers Energy Company
Clean Air Interstate Rule:In March 2005, the EPA adopted the Clean Air Interstate Rule that requires additional coal-fired electric generating plant emission controls for nitrogen oxides and sulfur dioxide. We plan to meet the nitrogen oxide requirements of this rule by year-round operation of our selective catalytic reduction control technology units, installation of low nitrogen oxide burners, and purchasing emission allowances. We plan to meet the sulfur dioxide requirements of this rule using sorbent injection, installation of flue gas desulfurization scrubbers and purchasing emission allowances. Our total cost for equipment installation is expected to reach approximately $700 million by 2015. Additional purchases of sulfur dioxide emission allowances in 2012 and 2013 will be needed for an estimated cost of $12 million per year, which we expect to recover from our customers through the PSCR process.
The Clean Air Interstate Rule was appealed to the U.S. Court of Appeals for the District of Columbia by a number of utilities and other companies. Final briefs are due September 5, 2007, with a decision expected in 2008. We cannot predict the outcome of these appeals.
Clean Air Mercury Rule:Also in March 2005, the EPA issued the Clean Air Mercury Rule, which requires initial reductions of mercury emissions from coal-fired electric generating plants by 2010 and further reductions by 2018. The Clean Air Mercury Rule was appealed to the U.S. Court of Appeals by a number of states and other entities. Final briefs were due July 13, 2007, with a decision expected in 2008. We cannot predict the outcome of these appeals.
In April 2006, Michigan'sMichigan’s governor announced a plan that would result in CE-15 Consumers Energy Company mercury emissions reductions of 90 percent by 2015. We are currently working with the MDEQ on the details of this rule; however, we have developed preliminary cost estimates and a mercury emissions reduction planscenario based on our best knowledge of control technology options and anticipatedinitially proposed requirements. Our plan includes expenditures of approximately $550 million for mercury control equipment and continuous emissions monitoring systems through 2014.

Routine Maintenance Classification:The EPA has alleged that some utilities have incorrectly classified plant modifications as “routine maintenance” rather than seeking permits from the EPA to modify the plant. We have received and responded to information requests from the EPA on this subject. We believe that we have properly interpreted the requirements of “routine maintenance.” If our interpretation is found to be incorrect, we may be required to install additional pollution controls at some or all of our coal-fired electric generating plants and potentially pay fines. Additionally, the viability of certain plants remaining in operation could be called into question.
Greenhouse gases:gases: Several legislative proposals have been introduced in the United States Congress that would require reductions in emissions of greenhouse gases, including carbon dioxide. On April 2, 2007, the U.S. Supreme Court ruled that the Clean Air Act gives the EPA the authority to regulate emissions of carbon dioxide and other greenhouse gases from automobiles. In its decision, the court ordered the EPA to revisit its contention that it has the discretion not to regulate greenhouse gas emissions from automobiles.
To the extent that greenhouse gas emission reduction rules come into effect, the mandatory emissions reduction requirements could have far-reaching and significant implications for the energy sector. We cannot estimate the effect of federal or state greenhouse gas policy on our future consolidated results of operations, cash flows, or financial position due to the uncertain nature of the policies at this time. However, we will continue to monitor greenhouse gas policy developments and assess and respond to their potential implications on our business operations.
Water:In March 2004, the EPA issued rules that govern electric generating plant cooling water intake systems. The rules require significant reduction in fish killed by operating equipment. EPA compliance options in the rule were challenged in court. In January 2007, the court rejected many of the compliance options favored by industry and remanded the bulk of the rule back to the EPA for reconsideration. The court'scourt’s ruling is expected to increase significantly the cost of complying with this rule. However, the cost to comply will not be known until the EPA'sEPA’s reconsideration is complete. At this time, the EPA has not established a schedule to address the court decision.

Competition and Regulatory Restructuring:The Customer Choice Act allows all of our electric customers to buy electric generation service from us or from an alternative electric supplier. At March 31,June 30, 2007, alternative electric suppliers were providing 283302 MW of generation service to ROA customers. This is 3 percent of our total distribution load and represents a decrease of 193 percent of ROA load compared to March 31,June 30, 2006. In prior orders, the MPSC approved recovery ofWe recover Stranded Costs incurred from 2002 through 2003 through a surcharge applied to ROA customers. If downward ROA trends continue, it maywill extend the time it takes to recover fully our Stranded Costs. It is difficult to predict future ROA customer trends, which affect our ability to recover timely ourthese Stranded Costs. ELECTRIC RATE CASE:
Electric Rate Case:In March 2007, we filed an application with the MPSC seeking an 11.25 percent authorized return on equity and an annual increase in revenues of $157 million. The increase includesseeks recovery of the costs associated with increased plant investment, increased equity investment, and greater operation and maintenance expenses. In May 2007, we filed supplemental testimony with the MPSC to include transaction costs from the sale of Palisades. In July 2007, we filed an amended application with the MPSC to include the proposed purchase of the Zeeland power plant, the approval of an energy efficiency program, and to make other revisions. The revised application seeks an annual increase in revenues of $282 million.

OTHER ELECTRIC BUSINESS UNCERTAINTIES THE
The MCV PARTNERSHIP: Partnership:The MCV Partnership, which leases and operates the MCV Facility, contracted to sell electricity to Consumers for a 35-year period beginning in 1990.
Underrecoveries related to the MCV PPA:The cost that we incur under the MCV PPA exceeds the recovery amount allowed by the MPSC. As a result, we estimate cash underrecoveries of capacity and fixed energy payments of $39 million in 2007. However, we use the direct savings from the RCP, after allocating a portion to customers, to offset a portion of our capacity and fixed energy underrecoveries expense. After September 15, 2007, we expect to claim relief under the regulatory outregulatory-out provision in the MCV PPA, thereby limiting our capacity and fixed energy payments to the MCV Partnership to the amounts that we collect from our customers. This action would eliminate our underrecoveries of capacity and fixed energy payments.
The MCV Partnership has notified us that it takes issue withopposes our intended exercise of the regulatory outregulatory-out provision after September 15, 2007. We believe that the provision is valid and fully effective, but cannot assure that itwe will prevail in the event of a dispute. If we are successful in exercising the regulatory outregulatory-out provision, the MCV Partnership may, under certain circumstances, have the right to terminate or reduce the amount of capacity sold under the MCV PPA. If the MCV Partnership terminates the MCV PPA or reduces the amount of capacity sold under the MCV PPA, we would seek to replace the lost capacity to maintain an adequate electric reserve margin. This could involve entering into a new PPA and (or) entering into electric capacity contracts on the open market. We cannot predict our ability to enter into such contracts at a reasonable price. We are also unable to predict regulatory approval of the terms and conditions of such contracts, or that the MPSC would allow full recovery of our incurred costs.
To comply with a prior MPSC order, we made a filing in May 2007 with the MPSC, which asked the MPSC to make a determination regarding whether it wished to reconsider the amount of the MCV PPA payments that we recover from customers. Also, in May 2007, the MCV Partnership filed an application with the MPSC seeking approval to increase our recovery of costs incurred under the MCV PPA. We are unable to predict the outcome of this request.these requests.

GAS BUSINESS OUTLOOK GROWTH:
Growth:In 2007, we project gas deliveries will decline slightly, on a weather-adjusted basis, from 2006 levels due to continuing conservation and overall economic conditions in the state of Michigan. Over the next five years, we expect gas deliveries to decline by less than one-half of one percent annually. Actual gas deliveries in future periods may be affected by: - fluctuations in weather conditions, - use by independent power producers, - competition in sales and delivery, - changes in gas commodity prices, - Michigan economic conditions, - the price of competing energy sources or fuels, - gas consumption per customer, - improvements in gas appliance efficiency, and - use of a Revenue Decoupling and Conservation Incentive mechanism.

that implementation of phase two of this standard will have a material effect on our consolidated financial statements. We expect to adopt the measurement date provisions of SFAS No. 158 in 2008.
FIN 48, ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES: Accounting for Uncertainty in Income Taxes:We adopted the provisions of FIN 48 on January 1, 2007. This interpretation provides a two-step approach for the recognition and measurement of uncertain tax positions taken, or expected to be taken, by a company on its income tax returns. The first step is to evaluate the tax position to determine if, based on management'smanagement’s best judgment, it is greater than 50 percent likely that we will sustain the tax position. The second step is to measure the appropriate amount of the benefit to recognize. This is done by estimating the potential outcomes and recognizing the greatest amount that has a cumulative probability of at least 50 percent. FIN 48 requires interest and penalties, if applicable, to be accrued on differences between tax positions recognized in our consolidated financial statements and the amount claimed, or expected to be claimed, on the tax return.
As a result of the implementation of FIN 48, we have identified additional uncertain tax benefits of $5 million as of January 1, 2007. Included in this amount is an increase in our valuation allowance of $7 million, increases to tax reserves of $55 million and a decrease to deferred tax liabilities of $57 million.
Consumers joins in the filing of a consolidated U.S. federal income tax return as well as unitary and combined income tax returns in several states. Consumers and its subsidiaries also file separate company income tax returns in several states. The only significant state tax paid by Consumers or any of its subsidiairessubsidiaries is in Michigan. However, since the Michigan Single Business Tax is not an income tax, it is not part of the FIN 48 analysis. The IRS has completed its audits for all the consolidated federal returns, of which Consumers is a member, for years through 2001. The federal income tax returns for the years 2002 through 2005 are open under the statute of limitations.
We have reflected a net interest liability of $1 million related to our uncertain income tax positions on our Consolidated Balance Sheets as of January 1, 2007. We have not accrued any penalties with respect to uncertain tax benefits. We recognize accrued interest and penalties, where applicable, related to uncertain tax benefits as part of income tax expense.
As of the date of adoption of FIN 48, we had valuation allowances against certain deferred tax assets totaling $22 million and other net uncertain tax positions of $55 million, resulting in total uncertain benefits of $77 million. Of this amount, $24 million would result in a decrease in our effective tax rate, if recognized. We are not expecting any material changes to our uncertain tax positions over the next 12 months.

New Accounting Standards Not Yet Effective
SFAS NO.No. 157, FAIR VALUE MEASUREMENTS: Fair Value Measurements:In September 2006, the FASB issued SFAS No. 157, effective for us January 1, 2008. The standard provides a revised definition of "fair value"“fair value” and gives guidance on how to measure the fair value of assets and liabilities. Under the standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly exchange between market participants. The standard does not expand the use of fair value in any new circumstances. However, additional disclosures will be required on the impact and reliability of fair value measurements reflected in our consolidated financial statements. The standard will also eliminate the existing prohibition of recognizing "day one"“day one” gains or losses on derivative instruments, and will generally require such gains and losses to be recognized through earnings. We are presently evaluating the impacts, if any, of implementing SFAS No. 157. We currently do not hold any derivatives that would involve day one gains or losses.

SFAS NO.No. 159, THE FAIR VALUE OPTION FOR FINANCIAL ASSETS AND FINANCIAL LIABILITIES, INCLUDING AN AMENDMENT TOThe Fair Value Option for Financial Assets and Financial Liabilities, Including an amendment to FASB STATEMENT NO.Statement No. 115:In February 2007, the FASB issued SFAS No. 159, effective for us January 1, 2008. This standard will give us the option to select certain financial instruments and other items, which otherwise are not required to be measured at fair value, and measure those items at fair value. If we choose to elect the fair value option for an item, we would recognize unrealized gains and losses associated with changes in the fair value of the item over time. The statement will also require disclosures for items for which the fair value option has been elected. We are presently evaluating whether we will choose to elect the fair value option for any financial instruments or other items.

EITF Issue 06-11, Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards:In June 2007, the FASB ratified EITF Issue 06-11, effective for us on a prospective basis beginning January 1, 2008. EITF 06-11 requires companies to recognize the income tax benefit realized from dividends or dividend equivalents that are charged to retained earnings and paid to employees
for non-vested equity-classified employee share-based payment awards as an increase to additional paid-in capital. We do not believe that implementation of this standard would have a material effect on our financial statements.

Corporate Structure:Consumers, a subsidiary of CMS Energy, a holding company, is a combination electric and gas utility company serving Michigan'sMichigan’s Lower Peninsula. Our customer base includes a mix of residential, commercial, and diversified industrial customers. We manage our business by the nature of services each provides and operate principally in two business segments: electric utility and gas utility. PRINCIPLES OF CONSOLIDATION:
Principles of Consolidation:The consolidated financial statements include Consumers, and all other entities in which we have a controlling financial interest or are the primary beneficiary, in accordance with FIN 46(R). We use the equity method of accounting for investments in companies and partnerships that are not consolidated, where we have significant influence over operations and financial policies, but are not the primary beneficiary. We eliminate intercompany transactions and balances. USE OF ESTIMATES:
Use of Estimates:We prepare our consolidated financial statements in conformity with U.S. GAAP. We are required to make estimates using assumptions that may affect the reported amounts and disclosures. Actual results could differ from those estimates.
We record estimated liabilities for contingencies in our consolidated financial statements when it is probable that a loss will be incurred in the future as a result of a current event, and when the amount can be reasonably estimated. For additional details, see Note 2,3, Contingencies. REVENUE RECOGNITION POLICY:
Revenue Recognition Policy:We recognize revenues from deliveries of electricity and natural gas, and the storage of natural gas when services are provided. We record sales tax on a net basis and exclude it from revenues. RECLASSIFICATIONS:
Reclassifications:We have reclassified certain prior year amounts for comparative purposes. These reclassifications did not affect consolidated net income for the periods presented. CE-29

New Accounting Standards Not Yet Effective:SFAS No. 157, Fair Value Measurements:In September 2006, the FASB issued SFAS No. 157, effective for us January 1, 2008. The standard provides a revised definition of "fair value"“fair value” and gives guidance on how to measure the fair value of assets and liabilities. Under the standard, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly exchange between market participants. The standard does not expand the use of fair value in any new circumstances. However, additional disclosures will be required on the impact and reliability of fair value measurements reflected in our consolidated financial statements. The standard will also eliminate the existing prohibition of recognizing "day one"“day one” gains or losses on derivative instruments, and will generally require such gains and losses to be recognized through earnings. We are presently evaluating the impacts, if any, of implementing SFAS No. 157. We currently do not hold any derivatives that would involve day one gains or losses.
SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities, Including an amendment to FASB Statement No. 115:In February 2007, the FASB issued SFAS No. 159, effective for us January 1, 2008. This standard will give us the option to select certain financial instruments and other items, which otherwise are not required to be measured at fair value, and measure those items at fair value. If we choose to elect the fair value option for an item, we would recognize unrealized gains and losses associated with changes in the fair value of the item over time. The statement will also require disclosures for items for which the fair value option has been elected. We are presently evaluating whether we will choose to elect the fair value option for any financial instruments or other items.

CE-31


Consumers Energy Company
EITF Issue 06-11, Accounting for Income Tax Benefits of Dividends on Share-Based Payment Awards: In June 2007, the FASB ratified EITF Issue 06-11, effective for us on a prospective basis beginning January 1, 2008. EITF 06-11 requires companies to recognize the income tax benefit realized from dividends or dividend equivalents that are charged to retained earnings and paid to employees for non-vested equity-classified employee share-based payment awards as an increase to additional paid-in capital. We do not believe that implementation of this standard would have a material effect on our financial statements.
2: CONTINGENCIES Asset Sales
Gross cash proceeds from the sale of assets totaled $338 million through June 30, 2007. The sale of assets resulted in a $2 million gain on our Consolidated Statements of Income.
Sale of Nuclear Assets:In April 2007, we sold Palisades to Entergy for $380 million. The final purchase price is subject to various closing adjustments such as working capital and capital expenditure adjustments and nuclear fuel usage and inventory adjustments. We have received $364 million as of June 2007; however, certain purchase price adjustments are not yet final. We also paid Entergy $30 million to assume ownership and responsibility for the Big Rock ISFSI. Because of the sale of Palisades, we paid the NMC, the former operator of Palisades, $7 million in exit fees and forfeited our $5 million investment in the NMC.
Entergy assumed responsibility for the future decommissioning of Palisades and for storage and disposal of spent nuclear fuel located at Palisades and the Big Rock ISFSI sites. At closing, we transferred $252 million in decommissioning trust fund balances to Entergy. We are refunding estimated excess decommissioning funds of $189 million to our retail customers through credits applied from June 2007 through December 2008 and have recorded this obligation as a regulatory liability on our Consolidated Balance Sheets. Modification to the terms of the transaction allowed us immediate access to additional excess decommissioning trust funds of $122 million. We have proposed a plan to refund these excess decommissioning fund balances through credits to our retail customers’ bills. This plan is under review by the MPSC in our current electric rate case filing. We recorded this balance as a regulatory liability on our Consolidated Balance Sheets.
The MPSC order approving the Palisades transaction allows us to recover the book value of Palisades, which we estimated at $314 million. As a result, we are refunding proceeds in excess of book value of $66 million to our retail customers through credits applied from June 2007 through December 2008. The final proceeds in excess of the book value are subject to closing adjustments and review by the MPSC. The MPSC order deferred ruling on the recovery of transaction costs, including the NMC exit fees, and the $30 million payment to Entergy related to the Big Rock ISFSI until our next general rate case. We deferred these costs as a regulatory asset on our Consolidated Balance Sheets as recovery is probable.
In April 2007, the NRC issued an order approving the transfer of the Palisades operating license. Intervenors have filed petitions for reconsideration of the NRC orders approving the transfer of the Palisades and Big Rock licenses. The NRC did not alter or stay the prior order approving the license transfer. We believe that it is unlikely that the NRC will conduct further proceedings or alter its prior orders, but we cannot predict the outcome of the matter.

(b)As of June 30, 2007, we have $56 million recorded as a regulatory asset for Palisades deferred costs of which $26 million relates to transaction costs. We estimate that we will incur an additional $2 million in selling expenses related to the Palisades transaction.
In the FERC’s February 2007 order regarding the Palisades transaction, the FERC granted our request to apply $11 million in FERC decommissioning trust fund balances for Palisades toward the Big Rock decommissioning shortfall, as described in Note 3, Contingencies, “Other Electric Contingencies – Nuclear Matters.” The order was contingent upon the NRC approving the transfer of operating licenses, which the NRC approved in April 2007. A clarification request was filed by a wholesale customer with the FERC. In July 2007, the FERC issued a clarification order requiring us to demonstrate that the fund did not have a surplus balance and if any surplus exists that we submit a refund plan.
Palisades Power Purchase Agreement:Entergy contracted to sell us 100 percent of the plant’s output up to its current annual average capacity of 798 MW under a 15-year power purchase agreement beginning in April 2007. We provided $30 million in security to Entergy for our power purchase agreement obligation in the form of a letter of credit. We estimate that capacity and energy payments under the Palisades power purchase agreement will be $180 million in 2007 and average $300 million per year thereafter.
Due to the Palisades power purchase agreement, the transaction is a sale and leaseback for accounting purposes. SFAS No. 98 specifies the accounting required for a seller’s sale and simultaneous leaseback involving real estate. We have continuing involvement with Palisades through security provided to

CE-33


Consumers Energy Company
Entergy for our power purchase agreement obligation and our DOE liability and other forms of involvement. As a result, we accounted for the Palisades plant, which is the real estate asset subject to the leaseback, as a financing for accounting purposes and not a sale. As a financing, no gain on the sale of Palisades was recognized on the Consolidated Statements of Income. We accounted for the remaining non-real estate assets and liabilities associated with the transaction as a sale.
As a financing, the Palisades plant remains on our Consolidated Balance Sheets and we continue to depreciate it. We recorded the related proceeds as a finance obligation with payments recorded to interest expense and the finance obligation based on the amortization of the obligation over the life of the Palisades power purchase agreement. The value of the finance obligation was based on an allocation of the transaction proceeds to the fair values of the net assets sold and fair value of the Palisades plant asset under the financing. As of June 30, 2007, the financing obligation was $194 million. We estimate future payments of $13 million per year over the next five years.
3:Contingencies
SEC ANDand DOJ INVESTIGATIONS: Investigations:During the period of May 2000 through January 2002, CMS MST engaged in simultaneous, prearranged commodity trading transactions in which energy commodities were sold and repurchased at the same price. These so called round-trip trades had no impact on previously reported consolidated net income, earnings per share or cash flows, but had the effect of increasing operating revenues and operating expenses by equal amounts.
CMS Energy is cooperating with an investigation by the DOJ concerning round-trip trading, which the DOJ commenced in May 2002. CMS Energy is unable to predict the outcome of this matter and what effect, if any, this investigation will have on its business. In March 2004, the SEC approved a cease-and-desist order settling an administrative action against CMS Energy related to round-trip trading. The order did not assess a fine and CMS Energy neither admitted to nor denied the order'sorder’s findings. The settlement resolved the SEC investigation involving CMS Energy and CMS MST. Also in March 2004, the SEC filed an action against three former employees related to round-trip trading at CMS MST. One of the individuals has settled with the SEC. CMS Energy is currently advancing legal defense costs for the remaining two individuals in accordance with existing indemnification policies. Those two individuals filed a motion to dismiss the SEC action, which was denied. CE-30 Consumers Energy Company SECURITIES CLASS ACTION LAWSUITS:
Securities Class Action Lawsuits: Beginning in May 2002, a number of complaints were filed against CMS Energy, Consumers and certain officers and directors of CMS Energy and its affiliates in the United States District Court for the Eastern District of Michigan. The cases were consolidated into a single lawsuit (the "Shareholder Action"“Shareholder Action”), which generally seeks unspecified damages based on allegations that the defendants violated United States securities laws and regulations by making allegedly false and misleading statements about CMS Energy'sEnergy’s business and financial condition, particularly with respect to revenues and expenses recorded in connection with round-trip trading by CMS MST. In January 2005, the court granted a motion to dismiss Consumers and three of the individual defendants, but denied the motions to dismiss CMS Energy and the 13 remaining individual defendants. In March 2006, the court conditionally certified a class consisting of "all“all persons who purchased CMS Common Stock during the period of October 25, 2000 through and including May 17, 2002 and who were damaged thereby." The court excluded purchasers of CMS Energy'sEnergy’s 8.75 percent Adjustable Convertible Trust Securities ("ACTS"(“ACTS”) from the class and, in response, a new class action lawsuit was filed on behalf of ACTS purchasers (the "ACTS Action"“ACTS Action”) against the same defendants named in the Shareholder Action. The settlement described in the following paragraph, if approved, will resolve both the Shareholder and ACTS Actions.

CE-34


Consumers Energy Company
On January 3, 2007, CMS Energy and other parties entered into a Memorandum of Understanding (the "MOU"“MOU”), subject to court approval, regarding settlement of the two class action lawsuits. The settlement was approved by a special committee of independent directors and by the full board of directors of CMS Energy. Both judged that it was in the best interests of shareholders to eliminate this business uncertainty. The MOU is expected to lead to a detailed stipulation of settlement that will be presented to the assigned federal judge and the affected class in the second quarter of 2007. Under the terms of the MOU, the litigation will be settled for a total of $200 million, including the cost of administering the settlement and any attorney fees the court awards. CMS Energy will make a payment of approximately $123 million plus an amount equivalent to interest on the outstanding unpaid settlement balance beginning on the date of preliminary approval of the court and running until the balance of the settlement funds is paid into a settlement account. In entering the MOU, CMS Energy makes no admission of liability under the Shareholder Action and the ACTS Action.
The parties executed a Stipulation and Agreement of Settlement dated May 22, 2007 (“Stipulation”) incorporating the terms of the MOU. On May 30, 2007, plaintiffs filed a “Motion for Order Preliminarily Approving Stipulation and Agreement of Settlement.” On June 7, 2007, the court entered a “Preliminary Order in Connection with Settlement Proceedings and Proposed Class Certification,” in which the court preliminarily approved the Stipulation and scheduled the settlement fairness hearing for September 6, 2007. In accordance with the Stipulation, CMS has paid approximately $1 million of the settlement amount to fund administrative expenses. The remaining $199 million and interest accruing thereon from the date of the June 7, 2007 order is payable ten business days after entry of the Order and Final Judgment following the September 6, 2007 hearing.
Out of the total settlement, CMS Energy'sEnergy’s insurers will pay approximately $77 million directly to the settlement account. CMS Energy took an approximate $123 million net pre-tax charge to 2006 earnings in the fourth quarter of 2006. In entering into the MOU,At June 30, 2007, CMS Energy makes no admissionhas a receivable of $77 million and a legal settlement liability underof $199 million recorded on its Consolidated Balance Sheets.
Katz Technology Litigation:In June 2007, Ronald A. Katz Technology Licensing, L.P. (“RAKTL”), filed a lawsuit in the Shareholder ActionUnited States District Court for the Eastern District of Michigan against CMS Energy and Consumers alleging patent infringement. RAKTL is claiming that automated customer service, bill payment services and gas leak reporting offered to our customers and accessed through toll free numbers infringe patents held by RAKTL. This case has been recently transferred to the ACTS Action. U.S.
District Court for Central District of California where other similar cases against public utilities, banks and other entities involving these patents are pending. We obtained an opinion from patent counsel that our automated telephone systems do not infringe on RAKTL patents and that those patents may be invalid. We will defend ourselves vigorously against these claims but cannot predict their outcome.
ELECTRIC CONTINGENCIES ELECTRIC ENVIRONMENTAL MATTERS:
Electric Environmental Matters:Our operations are subject to environmental laws and regulations. Costs to operate our facilities in compliance with these laws and regulations generally have been recovered in customer rates.
Routine Maintenance Classification:The EPA has alleged that some utilities have incorrectly classified plant modifications as "routine maintenance"“routine maintenance” rather than seeking permits from the EPA to modify the plant from the EPA.plant. We have received and responded to information requests from the EPA on this subject. We believe that we have properly interpreted the requirements of "routine“routine maintenance." If our interpretation is found to be incorrect, we may be required to install additional pollution controls at some or all of our coal-fired electric generating plants and potentially pay fines. Additionally, the viability of certain plants remaining in operation could be called into question.
Cleanup and Solid Waste:Under the Michigan Natural Resources and Environmental Protection Act, we expect that we will ultimately incur investigation and remedial action costs at a number of sites. We believe that these costs will be recoverable in rates under current ratemaking policies. CE-31 Consumers Energy Company
We are a potentially responsible party at several contaminated sites administered under the Superfund. Superfund liability is joint and several, meaning that many other creditworthy parties with substantial assets are potentially responsible with respect to the individual sites. Based on our experience, we estimate that our share of the total liability for the known Superfund sites will be between $1 million and $10 million. At March 31,June 30, 2007, we have recorded a liability for the minimum amount of our

CE-35


Consumers Energy Company
estimated probable Superfund liability in accordance with FIN 14. The timing of payments related to the remediation of our Superfund sites is uncertain. Any significant change in assumptions, such as different remediation techniques, nature and extent of contamination, and legal and regulatory requirements, could affect our estimate of remedial action costs and the timing of our remediation payments.
Ludington PCB:In October 1998, during routine maintenance activities, we identified PCB as a component in certain paint, grout, and sealant materials at Ludington. We removed and replaced part of the PCB material. Since proposing a plan to deal with the remaining materials, we have had several conversations with the EPA. The EPA has proposed a rule which would authorize continued use of such material in place, subject to certain restrictions. We are not able to predict when a final rule will be issued.
Electric Utility Plant Air Permit Issues:In April 2007, we received a Notice of Violation/Finding of Violation from the EPA alleging that fourteen of our utility boilers exceeded visible emission limits in their associated air permits. The utility boilers are located at the D.E. Karn/J.C. Weadock Generating Complex, the J.H. Campbell Plant, the BC Cobb Electric Generating Station and the JR Whiting Plant. We are preparing forpresently having discussions with the EPA regarding these allegations, but cannot predict the financial impact or outcome of this issue. LITIGATION:
Litigation:In 2003, a group of eight PURPA qualifying facilities (the plaintiffs), which sell power to us, filed a lawsuit in Ingham County Circuit Court. The lawsuit alleged that we incorrectly calculated the energy charge payments made pursuant to power purchase agreements with qualifying facilities. The judge deferred to the primary jurisdiction of the MPSC, dismissing the circuit court case without prejudice. In February 2005, the MPSC issued an order in the 2004 PSCR plan case concluding that we have been correctly administering the energy charge calculation methodology. The plaintiffs have appealed the MPSC order to the Michigan Court of Appeals. The plaintiffs also filed suit in the United States Court for the Western District of Michigan, which the judge subsequently dismissed on the basis that the pending state court litigation would fully resolve any federal issue before the courts. The plaintiffs then appealed the dismissal to the United States Court of Appeals, which held that the district court matter should be stayed rather than dismissed, pending the outcome of the state appeal. We cannot predict the outcome of these appeals. CE-32 Consumers Energy Company
ELECTRIC RATE MATTERS ELECTRIC
Electric ROA:The Customer Choice Act allows electric utilities to recover their net Stranded Costs. In prior orders, the MPSC approved recovery of Stranded Costs incurred from 2002 through 2003 plus the cost of money through the period of collection. At March 31,June 30, 2007, we had a regulatory asset for Stranded Costs of $66$67 million on our Consolidated Balance Sheets. We collect these Stranded Costs through a surcharge on ROA customers. At March 31,June 30, 2007, alternative electric suppliers were providing 283302 MW of generation service to ROA customers, which represent a decrease of 193 percent of ROA load compared to March 31,June 30, 2006. This downward trend has affected negatively our ability to recover timely ourthese Stranded Costs. If downward ROA trends continue, it may require legislative or regulatory assistance to recover fully our Stranded Costs. However, the Customer Choice Act allows electric utilities to recover their net Stranded Costs. It is difficult to predict future ROA customer trends and their effect on the timely recovery of Stranded Costs. POWER SUPPLY COSTS:
Power Supply Costs:To reduce the risk of high power supply costs during peak demand periods and to achieve our reserve margin target, we purchase electric capacity and energy contracts for the physical delivery of electricity primarily in the summer months and to a lesser degree in the winter months. We have purchased capacity and energy contracts covering the reserve margin requirements for 2007 and

CE-36


Consumers Energy Company
covering partially the estimated reserve margin requirements for 20072008 through 2010. As a result, we have an asset of $62 million for unexpired seasonal capacity and energy contracts at March 31, 2007. As of March 31,June 30, 2007, we expect capacity costs for these primarily seasonal electric capacity and energy contracts to be $14$17 million for 2007.
PSCR:The PSCR process allows recovery of reasonable and prudent power supply costs. The MPSC reviews these costs for reasonableness and prudency in annual plan proceedings and in plan reconciliation proceedings. The following table summarizes our PSCR reconciliation filings with the MPSC:

2007 PSCR Plan:In September 2006, we filed our 2007 PSCR plan with the MPSC. The plan sought authorization to incorporate our 2005 and 2006 PSCR underrecoveries into our 2007 PSCR monthly factor. In December 2006, the MPSC issued a temporary order allowing us to implement our 2007 PSCR monthly factor on January 1, 2007, as filed. The order also allowed us to continue to roll in prior year underrecoveries and overrecoveries in future PSCR plans. CE-33 Consumers Energy Company
Underrecoveries in power supply costs are included in Accrued power supply and gas revenue on our Consolidated Balance Sheets. We expect to recover fully all of our PSCR costs. When we are unable to collect these costs as they are incurred, there is a negative impact on our cash flows from electric utility operations. We cannot predict the outcome of these proceedings. ELECTRIC RATE CASE:
Electric Rate Case:In March 2007, we filed an application with the MPSC seeking an 11.25 percent authorized return on equity and an annual increase in revenues of $157 million as shown inmillion. In May 2007, we filed supplemental testimony with the following table: MPSC to include transaction costs from the sale of Palisades. In July 2007, we filed an amended application with the MPSC to include the proposed purchase of the Zeeland power plant, the approval of an energy efficiency program, and to make other revisions.
In July 2007, we also filed a motion for partial and immediate rate relief, which seeks the following:

(b) The nuclear surcharge is a proposal to earn a return on funds spent on Big Rock spent nuclear fuel storage, decommissioning, and site restoration expenditures until pending DOE litigation and future MPSC proceedings regarding this issue are concluded. (c) Palisades power purchase agreement costs are currently offset through feedback in the PSCR related to Palisades base rate revenues via a base rate recovery credit. The Palisades base rate recovery credit will be discontinued once Palisades' costs are removed from base rates. If approved as requested, the rate requests would go into effect in January 2008 and would apply to all retail electric customers.
We cannot predict the amount or timing of any MPSC decision on the requests.
OTHER ELECTRIC CONTINGENCIES THE
The MCV PPA:The MCV Partnership, which leases and operates the MCV Facility, contracted to sell 1,240 MW of electricity to Consumers under a 35-year power purchase agreement beginning in 1990. We estimate that capacity and energy payments under the MCV PPA will be $620 million per year. The MCV PPA and the associated customer rates are unaffected by the November 2006 sale of our interest in the MCV Partnership.
Underrecoveries related to the MCV PPA:The cost that we incur under the MCV PPA exceeds the recovery amount allowed by the MPSC. We estimate cash underrecoveries of our capacity and fixed energy payments of $39 million in 2007 of which we have expensed $13$30 million during the threesix months ended March 31,June 30, 2007. However, we use savings from the RCP, after allocating a portion to customers, to offset a portion of our capacity and fixed energy underrecoveries expense.

CE-38


Consumers Energy Company
We recover from our customers the capacity and fixed energy charges based on availability, up to an availability cap of 88.7 percent as established in previous MPSC orders. The MCV Partnership has filed an application with the MPSC requesting the elimination of the 88.7 percent availability cap. We cannot predict the outcome of this matter.
RCP:In January 2005, we implemented the MPSC-approved RCP with modifications. The RCP allows us to recover the same amount of capacity and fixed energy charges from customers as approved CE-34 Consumers Energy Company in prior MPSC orders. However, we are able to dispatch the MCV Facility based on natural gas market prices. This results in fuel cost savings for the MCV Facility, which the MCV Partnership shares with us. The RCP also requires us to contributecontributions of $5 million annually to a renewable resources program. As of MarchJune 30, 2007, we have contributedcontributions of $12 million were made to the renewable resources program. The underlying RCP agreement between Consumers and the MCV Partnership extends through the term of the MCV PPA. However, either party may terminate that agreement under certain conditions. In January 2007, the Michigan Attorney General filed an appeal with the Michigan Supreme Court regarding the MPSC'sMPSC’s order approving the RCP. We cannot predictThe Supreme Court denied the outcome of thisAttorney General’s request to further consider the matter. Regulatory Out
Regulatory-out Provision in the MCV PPA:After September 15, 2007, we expect to claim relief under the regulatory outregulatory-out provision in the MCV PPA, thereby limiting our capacity and fixed energy payments to the MCV Partnership to the amounts that we collect from our customers. The MCV Partnership has notified us that it takes issue withopposes our intended exercise of the regulatory outregulatory-out provision. We believe that the provision is valid and fully effective, but cannot assure that itwe will prevail in the event of a dispute. If we are successful in exercising the regulatory outregulatory-out provision, the MCV Partnership may, under certain circumstances, have the right to terminate or reduce the amount of capacity sold under the MCV PPA from 1,240 MW to 806 MW, which could affect our reserve margin. Presently, we are in arbitration with the MCV Partnership regarding a dispute on the timing of MCV Partnership’s termination rights prescribed in the MCV PPA.
We anticipate that the MPSC will review our exercise of the regulatory outregulatory-out provision and the likely consequences of such action in 2007. It is possible that in the event that the MCV Partnership ceases performance under the MCV PPA, prior orders could limit recovery of replacement power costs to the amounts that the MPSC authorized for recovery under the MCV PPA. Depending on the cost of replacement power, this could result in our costs exceeding the recovery amount allowed by the MPSC. We cannot predict the outcome of these matters.
To comply with a prior MPSC order, we made a filing in May 2007 with the MPSC, which asked the MPSC to make a determination regarding whether it wished to reconsider the amount of the MCV PPA payments that we recover from customers. We are unable to predict the outcome of this request. THE SALE OF NUCLEAR ASSETS AND THE PALISADES POWER PURCHASE AGREEMENT: Sale of
Nuclear Assets: In April 2007, we sold Palisades to Entergy for $380 million. The final purchase price was subject to various closing adjustments such as working capital and capital expenditure adjustments and nuclear fuel usage and inventory adjustments resulting in us receiving $361 million. We also paid Entergy $30 million to assume ownership and responsibility for the Matters:Big Rock ISFSI. Because of the sale of Palisades, we will also pay the NMC, the former operator of the Palisades plant, $7 million in exit fees and will forfeit our investment in the NMC of $5 million. Entergy will assume responsibility for the future decommissioning of the Palisades plant and for storage and disposal of spent nuclear fuel located at the Palisades and the Big Rock ISFSI sites. At closing, we transferred $252 million in decommissioning trust fund balances to Entergy. The MPSC order approving the Palisades transaction allows us to recover the estimated $314 million book value of the Palisades plant. As a result, we estimate that we will credit excess proceeds of $66 million to our retail customers through refunds applied over the remainder of 2007 and 2008. The MPSC order deferred ruling on the recovery of $30 million in estimated transaction costs, including the NMC exit fees, and the $30 million payment to Entergy related to the Big Rock ISFSI until the next general rate case. We will defer these costs as a regulatory asset on our Consolidated Balance Sheets as recovery is probable. In April 2007, the NRC, through its staff, issued an order approving the transfer of the Palisades operating license. Subsequently, in April 2007, the NRC issued an order requiring that certain intervenors be given, under a protective order, information related to the buyer's financial capability. If, CE-35 Consumers Energy Company after the review of the information, the intervenors wished to seek additional proceedings on the license transfer, the NRC would consider the request. The NRC did not alter or stay the prior order approving the license transfer. We believe that it is unlikely that the NRC will conduct further proceedings, but we cannot predict the outcome of the matter. These events did not hold up the closing of the sale of Palisades. The following table summarizes the estimated impacts of the Palisades and the Big Rock ISFSI transactions:

(a) In the FERC's February 2007 order regarding the Palisades transaction, the FERC granted our request to apply $11 million in FERC decommissioning trust fund balances for the Palisades plant toward the Big Rock decommissioning shortfall, as described in "Big Rock Nuclear Plant Decommissioning" within this section. The order was contingent upon the NRC approving the transfer of operating licenses, which the NRC approved in April 2007. This determination is the subject of a clarification request filed by a wholesale customer with the FERC. (b) Final proceeds in excess of the book value are subject to closing adjustments and review by the MPSC. (c) In the MPSC's March 2007 order approving the Palisades transaction, the MPSC indicated that $189 million of MPSC jurisdictional decommissioning funds must be credited to our retail customers through refunds applied over the remainder of 2007 and 2008. Final disposition of these funds is subject to closing date balances and is subject to review by the MPSC. The remaining estimated $116 million of the MPSC jurisdictional decommissioning funds, which is subject to closing date reconciliation will be used to benefit our retail customers and is expected to be addressed in a separate filing made with the MPSC. Palisades Power Purchase Agreement: Entergy contracted to sell us 100 percent of the plant's output up to its current annual average capacity of 798 MW under a 15-year power purchase agreement beginning in April 2007. We provided $30 million in security to Entergy for our power purchase agreement obligation in the form of a letter of credit. We estimate that capacity and energy payments under the Palisades power purchase agreement will be $300 million per year. Because of the Palisades power purchase agreement, the transaction is a sale and leaseback for accounting purposes. SFAS No. 98 specifies the accounting required for a seller's sale and simultaneous leaseback involving real estate. We will have continuing involvement with the Palisades plant through security provided to Entergy for our power purchase agreement obligation, our DOE liability, and other forms of involvement. As a result, we will account for the Palisades plant, which is the real estate asset subject to the leaseback, as a financing for accounting purposes and not a sale. We will account for the remaining non-real estate assets and liabilities associated with the transaction as a CE-36 Consumers Energy Company sale. As a financing, the Palisades plant will remain on our Consolidated Balance Sheets and the related proceeds will be recorded as a financing obligation. The value of the finance obligation is based on an allocation of the transaction proceeds to the fair values of the net assets sold and fair value of the Palisades plant assets under the financing. BIG ROCK NUCLEAR PLANT DECOMMISSIONING: Decommissioning:
The MPSC and the FERC regulate the recovery of costs to decommission the Big Rock nuclear plant.Rock. In December 2000, funding of the Big Rock trust fund stopped because the MPSC-authorized decommissioning surcharge collection period expired. In a March 2007 report to the MPSC, we indicated that we have managed the decommissioning trust fund to meet the annual NRC financial assurance requirements by withdrawing NRC radiological decommissioning costs from the trust fund and initially funding non-NRC greenfield costs out of corporate funds. In March 2006, we contributed corporate funds of $16 million to the trust fund to support the NRC radiological decommissioning costs. Excluding the additional nuclear fuel storage costs due to the DOE's failure to accept spent nuclear fuel on schedule, we are projecting theThe level of funds provided by the trust will fallfell short of the amount needed to complete decommissioning by an additional $36 million.

we have funded in future filings with the MPSC and have a $36$122 million regulatory asset recorded on our Consolidated Balance Sheets as of March 31,June 30, 2007. Cost projections
Actual expenditures for Big Rock indicate a decommissioning cost of $389totaled $387 million as of March 2007, of which we have incurred $387 million. These amounts excludeJune 30, 2007. This total excludes the additional costs for spent nuclear fuel storage due to the DOE'sDOE’s failure to accept this spent nuclear fuel on schedule. They also exclude post September 11schedule as well as certain increased security costs that we are recovering through the security cost recovery provisions of Public Act 609 of 2002. These activities had no material impact on consolidated net income. Any remaining Big Rock decommissioning costs will initially be funded out of corporate funds. NUCLEAR MATTERS:
Nuclear Fuel Cost:We amortized nuclear fuel cost to fuel expense based on the quantity of heat produced for electric generation. For nuclear fuel used after April 6, 1983, we charged certain disposal costs to nuclear fuel expense, recovered these costs through electric rates, and remitted them to the DOE quarterly. We elected to deferdeferred payment for disposal of spent nuclear fuel burned before April 7, 1983. Our DOE liability is $154$156 million at March 31,June 30, 2007. This amount includes interest, which is payable upon the first delivery of spent nuclear fuel to the DOE. We have recovered, through electric rates, the amount of this liability, excluding a portion of interest. In conjunction with the sale of Palisades and the Big Rock ISFSI, we retained this obligation and provided $155 million in security to Entergy for this obligation in the form of a letter of credit.
DOE Litigation:In 1997, a U.S. Court of Appeals decision confirmed that the DOE was to begin accepting deliveries of spent nuclear fuel for disposal by January 1998. Subsequent U.S. Court of Appeals litigation, in which we and other utilities participated, has not been successful in producing more specific relief for the DOE'sDOE’s failure to accept the spent nuclear fuel.
There are twoseveral court decisions that support the right of utilities to pursue damage claims in the United States Court of Claims against the DOE for failure to take delivery of spent nuclear fuel. Over 60 utilities have initiated litigation in the United States Court of Claims. We filed our complaint in December 2002. If our litigation against the DOE is successful, we plan to use any recoveries as reimbursement for the incurred costs of spent nuclear fuel storage during our ownership of Palisades CE-37 Consumers Energy Company and Big Rock. We can make no assurance that the litigation against the DOE will be successful. The sale of Palisades and the Big Rock ISFSI did not transfer the right to any recoveries from the DOE related to costs of spent nuclear fuel storage incurred during our ownership of Palisades and Big Rock.
In 2002, the site at Yucca Mountain, Nevada was designated for the development of a repository for the disposal of high-level radioactive waste and spent nuclear fuel. We expect that the DOE, in due course,ultimately, will submit a final license application to the NRC for the repository. The application and review process is estimated to take several years. Insurance: We maintained nuclear insurance coverage on our nuclear plants until Palisades and the Big Rock ISFSI were sold in April 2007. At Palisades, we maintained nuclear property insurance from NEIL totaling $2.750 billion and insurance that would partially cover the cost of replacement power during certain prolonged accidental outages. Because NEIL is a mutual insurance company, we could be subject to assessments of up to $30 million in any policy year if insured losses in excess of NEIL's maximum policyholders surplus occur at our, or any other member's, nuclear facility. NEIL's policies include coverage for acts of terrorism. At Palisades, we maintained nuclear liability insurance for third-party bodily injury and off-site property damage resulting from a nuclear energy hazard for up to approximately $10.761 billion, the maximum insurance liability limits established by the Price-Anderson Act. Part of the Price-Anderson Act's financial protection is a mandatory industry-wide program under which owners of nuclear generating facilities could be assessed if a nuclear incident occurs at any nuclear generating facility. The maximum assessment against us could be $101 million per occurrence, limited to maximum annual installment payments of $15 million. We also maintained insurance under a program that covers tort claims for bodily injury to nuclear workers caused by nuclear hazards. The policy contains a $300 million nuclear industry aggregate limit. Under a previous insurance program providing coverage for claims brought by nuclear workers, we remain responsible for a maximum assessment of up to $6 million. This requirement will end December 31, 2007. Big Rock was insured for nuclear liability up to $544 million through nuclear insurance and the NRC indemnity, and we maintained a nuclear property insurance policy from NEIL. Insurance policy terms, limits, and conditions are subject to change during the year as we renew our policies.
GAS CONTINGENCIES GAS ENVIRONMENTAL MATTERS:
Gas Environmental Matters:We expect to incur investigation and remediation costs at a number of sites under the Michigan Natural Resources and Environmental Protection Act, a Michigan statute that covers environmental activities including remediation. These sites include 23 former manufactured gas plant facilities. We operated the facilities on these sites for some part of their operating lives. For some of these sites, we have no current ownership or may own only a portion of the original site. In 2005, we estimated our remaining costs to be between $29 million and $71 million, based on 2005 discounted costs, using a discount rate of three percent. The discount rate represents a 10-year average of U.S. Treasury bond rates reduced for increases in the consumer price index. We expect to fund most of these costs through proceeds derived from a settlement with insurers and MPSC-approved rates. At March 31,June 30, 2007, we have a liability of $22$21 million, net of $60$61 million of expenditures incurred to date, and a regulatory asset of $55$53 million. The timing of payments related to the remediation of our CE-38 Consumers Energy Company manufactured gas plant sites is uncertain. Any significant change in assumptions, such as an increase in the number of sites, different remediation techniques, nature and extent of contamination, and legal and regulatory requirements, could affect our estimate of remedial action costs and the timing of our remediation payments.

GAS RATE MATTERS GAS COST RECOVERY:
Gas Cost Recovery:The GCR process is designed to allow us to recover all of our purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices for prudency in annual plan and reconciliation proceedings.
The following table summarizes our GCR reconciliation filings with the MPSC:

Overrecoveries in cost of gas sold are included in Accrued rate refunds on our Consolidated Balance Sheets.
GCR plan for year 2005-2006:In November 2005, the MPSC issued an order for our 2005-2006 GCR Plan year, which resulted in approval of a settlement agreement and established a fixed price cap of $10.10 per mcf for the December 2005 through March 2006 billing period. We were able to maintain our GCR billing factor below the authorized level for that period. The order was appealed to the Michigan Court of Appeals by one intervenor. We are unable to predict the outcome of this proceeding.
GCR plan for year 2006-2007:In August 2006, the MPSC issued an order for our 2006-2007 GCR Plan year, which resulted in approval of a settlement agreement that allowed a base GCR ceiling factor of $9.48 per mcf for the 12-month period of April 2006 through March 2007. We were able to maintain our GCR billing factor below the authorized level for that period.
GCR plan for year 2007-2008:In December 2006, we filed an application with the MPSC seeking approval of a GCR plan for the 12-month period of April 2007 through March 2008. Our request proposed using a GCR factor consisting of: -
a base GCR ceiling factor of $8.47 per mcf, plus
a quarterly GCR ceiling price adjustment contingent upon future events.
In June 2007, all parties signed a settlement agreement and filed the agreement with the MPSC for approval. All parties agreed to lower the ceiling on the quarterly adjustment mechanism from $3.50 per mcf to $3.00 per mcf.

In July 2007, the MPSC issued an order for our 2007-2008 GCR Plan year, which resulted in approval of the settlement agreement.
The GCR billing factor is adjusted monthly in order to minimize the over or underrecovery amounts in our annual GCR reconciliation. Our GCR billing factor for the month of MayAugust 2007 is $8.24$7.90 per mcf. CE-39 Consumers Energy Company
2007 GAS RATE CASE: Gas Rate Case:In February 2007, we filed an application with the MPSC seeking an 11.25 percent authorized return on equity along with an $88 million annual increase in our gas delivery and transportation rates, of which $17 million would be contributed to a low income energy efficiency fund.rates. We have proposed the use of a Revenue Decoupling and Conservation Incentive Mechanism for residential and general service rate classes, to help assure a reasonable opportunitywhich partially separates the collection of fixed costs from gas sales and enhances the utility’s ability to recover its fixed costs regardless.
The MPSC Staff and intervenors filed testimony on July 20, 2007. In its testimony, the MPSC Staff recommended a 10.5 percent authorized return on equity with a $35 million annual increase in our gas delivery and transportation rates. The schedule established by the MPSC for processing this case could allow for a final order by the end of sales levels. 2007.

DERIVATIVE INSTRUMENTS:
Derivative Instruments: In order to limit our exposure to certain market risks, we may enter into various risk management contracts, such as swaps, options, futures, and forward contracts. These contracts, used primarily to manage our exposure to changes in interest rates and commodity prices, are entered into for purposes other than trading. We enter into these contracts using established policies and procedures, under the direction of both: - an executive oversight committee consisting of senior management representatives, and - a risk committee consisting of business unit managers. CE-43 Consumers Energy Company
an executive oversight committee consisting of senior management representatives, and
a risk committee consisting of business unit managers.
The contracts we use to manage market risks may qualify as derivative instruments that are subject to derivative and hedge accounting under SFAS No. 133. If a contract is a derivative, it is recorded on our consolidated balance sheet at its fair value. We then adjust the resulting asset or liability each quarter to reflect any change in the market value of the contract, a practice known as marking the contract to market. From time to time, we enter into cash flow hedges. If a derivative qualifies for cash flow hedge accounting treatment, the changes in fair value (gains or losses) are reported in AOCI; otherwise, the changes are reported in earnings.

If a derivative qualifies for cash flow hedge accounting treatment and gains or losses are recorded in AOCI, those gains or losses will be reclassified into earnings in the same period or periods the hedged forecasted transaction affects earnings. If a cash flow hedge is terminated early because it is determined that the forecasted transaction will not occur, any gain or loss recorded in AOCI at that date is recognized immediately in earnings. If a cash flow hedge is terminated early for other economic reasons, any gain or loss as of the termination date is deferred and then reclassified to earnings when the forecasted transaction affects earnings. The ineffective portion, if any, of all hedges is recognized in earnings.
To determine the fair value of our derivatives, we use information from external sources (i.e., quoted market prices and third-partythird party valuations), if available. For certain contracts, this information is not available and we use mathematical valuation models to value our derivatives. These models require various inputs and assumptions, including commodity market prices and volatilities, as well as interest rates and contract maturity dates. The cash returns we actually realize on these contracts may vary, either positively or negatively, from the results that we estimate using these models. As part of valuing our derivatives at market, we maintain reserves, if necessary, for credit risks arising from the financial condition of our counterparties.
The majority of our commodity purchase and sale contracts are not subject to derivative accounting under SFAS No. 133 because: - they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas), - they qualify for the normal purchases and sales exception, or - there is not an active market for the commodity.
they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas),
they qualify for the normal purchases and sales exception, or
there is not an active market for the commodity.
Our coal purchase contracts are not derivatives because there is not an active market for the coal we purchase. If an active market for coal develops in the future, some of these contracts may qualify as derivatives and the resulting mark-to-market impact on earnings could be material.
Derivative accounting is required for certain contracts used to limit our exposure to commodity price risk. At March 31,June 30, 2007, the fair value of these derivative contracts was immaterial. CE-44

Pension Plan:The Pension Plan includes funds for most of our current employees, the employees of our subsidiaries, and Panhandle, a former subsidiary. The Pension Plan'sPlan’s assets are not distinguishable by company.
In April 2007, we sold the Palisades nuclear plant to Entergy. Employees transferred to Entergy as a result of the sale no longer participate in our retirement benefit plans. In April 2007, we recorded a net reduction of $27 million in pension SFAS No. 158 regulatory assets with a corresponding decrease of $27 million in pension liabilities on our Consolidated Balance Sheets. We also recorded a net reduction of $15 million in OPEB regulatory SFAS No. 158 assets with a corresponding decrease of $15 million in OPEB liabilities. The following table shows the net adjustment:

Beginning May 1, 2007, the CMS Energy Common Stock Fund willis no longer be an investment option available for new investments in the401(k) Savings Plan and the employer'semployer’s match willis no longer be in CMS Energy Stock. Participants will have an opportunity to reallocate investments in the CMS Energy Stock Fund to other plan investment alternatives. Beginning November 1, 2007, any remaining shares in the CMS Energy Stock Fund will be sold and the sale proceeds will be reallocated to other plan investment options. At March 31,June 30, 2007, there were 109 million shares of CMS Energy Common Stock in the CMS Energy Stock Fund.
SFAS No. 158, Employers'Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans - an amendment of FASB Statements No. 87, 88, 106, and 132(R):In September 2006, the FASB issued SFAS No. 158. Phase one of this standard required us to recognize the funded status of our defined benefit postretirement plans on our Consolidated Balance Sheets at December 31, 2006. Phase one was implemented in December 2006. Phase two of this standard requires that we change our plan measurement date from November 30 to December 31, effective December 31, 2008. We do not believe that implementation of phase two of this standard will have a material effect on our consolidated financial statements. We expect to adopt the measurement date provisions of SFAS No. 158 in 2008. CE-45 Consumers Energy Company

7:Asset Retirement Obligations
SFAS NO.No. 143, ACCOUNTING FOR ASSET RETIREMENT OBLIGATIONS: Accounting for Asset Retirement Obligations:This standard requires companies to record the fair value of the cost to remove assets at the end of their useful life, if there is a legal obligation to remove them. Fair value, to the extent possible, should include a market risk premium for unforeseeable circumstances. No market risk premium was included in our ARO fair value estimate since a reasonable estimate could not be made. If a five percent market risk premium were assumed, our ARO liability would increase by $25$5 million.
If a reasonable estimate of fair value cannot be made in the period in which the ARO is incurred, such as for assets with indeterminate lives, the liability is to be recognized when a reasonable estimate of fair value can be made. Generally, gas transmission and electric and gas distribution assets have indeterminate lives. Retirement cash flows cannot be determined and there is a low probability of a retirement date. Therefore, no liability has been recorded for these assets or associated obligations related to potential future abandonment. Also, no liability has been recorded for assets that have insignificant cumulative disposal costs, such as substation batteries. The measurement of the ARO liabilities
FASB Interpretation No. 47,Accounting for Palisades and Big Rock include use of decommissioning studies that largely utilize third-party cost estimates. FASB INTERPRETATION NO. 47, ACCOUNTING FOR CONDITIONAL ASSET RETIREMENT OBLIGATIONS: Conditional Asset Retirement Obligations:This Interpretation clarified the term "conditional“conditional asset retirement obligation"obligation�� as used in SFAS No. 143. The

term refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event.

In October 2004, the MPSC initiated a generic proceeding to review SFAS No. 143, FERC Order No. 631, Accounting, Financial Reporting, and Rate Filing Requirements for Asset Retirement Obligations, and related accounting and ratemaking issues for MPSC-jurisdictional electric and gas utilities. In June 2007, the MPSC issued an order that requires:
the MPSC Staff to advise the MPSC whether there are any FERC accounts, rules or procedures that should be adopted by reference or changed, and
the use of a revised calculation for cost of removal estimates derived from applying SFAS No. 143, which includes the use of standard retirement units.
We will also be required to file a new gas depreciation study by August 2006,1, 2008, using 2007 removal costs as the ALJ issuedbasis for the calculation and a Proposalnew electric depreciation study by August 3, 2009, using 2008 removal costs as the basis for Decision that included recommendations that the MPSC: - adopt SFAS No. 143 and FERC Order No. 631 for accounting purposes but not for ratemaking purposes, - consider adopting standardized retirement units for certain accounts, - consider revising the method of determining cost of removal, and CE-47 Consumers Energy Company - withhold approving blanket regulatory asset and regulatory liability accounting treatment related to AROs, stating that modifications to the MPSC's Uniform System of Accounts should precede any such accounting approval. We consider the proceeding a clarification of accounting and reporting issues that relate to all Michigan utilities. We cannot predict the outcome of the proceeding. 7: INCOME TAXES calculation.

As a result of the implementation of FIN 48, we have identified additional uncertain tax benefits of $5 million as of January 1, 2007. Included in this amount is an increase in our valuation allowance of $7 million, increases to tax reserves of $55 million and a decrease to deferred tax liabilities of $57 million.
Consumers joins in the filing of a consolidated U.S. federal income tax return as well as unitary and combined income tax returns in several states. Consumers and its subsidiaries also file separate company income tax returns in several states. The only significant state tax paid by Consumers or any of its subsidiaries is in Michigan. However, since the Michigan Single Business Tax is not an income tax, it is not part of the FIN 48 analysis. The IRS has completed its audits for all the consolidated federal returns, of which Consumers is a member, for years through 2001. The federal income tax returns for the years 2002 through 2005 are open under the statute of limitations.

We have reflected a net interest liability of $1 million related to our uncertain income tax positions on our Consolidated Balance Sheets as of January 1, 2007. We have not accrued any penalties with respect to uncertain tax benefits. We recognize accrued interest and penalties, where applicable, related to uncertain tax benefits as part of income tax expense.
As of the date of adoption of FIN 48, we had valuation allowances against certain deferred tax assets totaling $22 million and other net uncertain tax positions of $55 million, resulting in total uncertain benefits of $77 million. Of this amount, $24 million would result in a decrease in our effective tax rate, CE-48 Consumers Energy Company if recognized.

CMS ENERGY
GAS INDEX PRICE REPORTING LITIGATION
Texas-Ohio Energy, Inc. filed a putative class action lawsuit in the United States District Court for the Eastern District of California in November 2003 against a number of energy companies engaged in the sale of natural gas in the United States (including CMS Energy). The complaint alleged defendants entered into a price-fixing scheme by engaging in activities to manipulate the price of natural gas in California. The complaint alleged violations of the federal Sherman Act, the California Cartwright Act, and the California Business and Professions Code relating to unlawful, unfair and deceptive business practices. The complaint sought both actual and exemplary damages for alleged overcharges, attorneys'attorneys’ fees and injunctive relief regulating defendants'defendants’ future conduct relating to pricing and price reporting. In April 2004, a Nevada Multidistrict Litigation (MDL) Panel ordered the transfer of the Texas-Ohio case to a pending MDL matter in the Nevada federal district court that at the time involved seven complaints originally filed in various state courts in California. These complaints make allegations similar to those in the Texas-Ohio case regarding price reporting, although none contain a federal Sherman Act claim. In November 2004, those seven complaints, as well as a number of others that were originally filed in various state courts in California and subsequently transferred to the MDL proceeding, were remanded back to California state court. The Texas-Ohio case remained in Nevada federal district court, and defendants, with CMS Energy joining, filed a motion to dismiss. The court issued an order granting the motion to dismiss on April 8, 2005 and entered a judgment in favor of the defendants on April 11, 2005. Texas-Ohio has appealed the dismissal to the Ninth Circuit Court of Appeals.
Three federal putative class actions, Fairhaven Power Company v. Encana Corp. et al., Utility Savings & Refund Services LLP v. Reliant Energy Resources Inc. et al., and Abelman Art Glass v. Encana Corp. et al., all of which make allegations similar to those in the Texas-Ohio case regarding price manipulation and seek similar relief, were originally filed in the United States District Court for the Eastern District of California in September 2004, November 2004 and December 2004, respectively. The Fairhaven and Abelman Art Glass cases also include claims for unjust enrichment and a constructive trust. The three complaints were filed against CMS Energy and many of the other defendants named in the Texas-Ohio case. In addition, the Utility Savings case names CMS MST and Cantera Resources Inc. (Cantera Resources Inc. is the parent of Cantera Natural Gas, LLC. and CMS Energy is required to indemnify Cantera Natural Gas, LLC and Cantera Resources Inc. with respect to these actions.)
The Fairhaven, Utility Savings and Abelman Art Glass cases have been transferred to the MDL proceeding, where the Texas-Ohio case was pending. Pursuant to stipulation by the parties and court order, defendants were not required to respond to the Fairhaven, Utility Savings and Abelman Art Glass complaints until the court ruled on defendants'defendants’ motion to dismiss in the Texas-Ohio case. Plaintiffs subsequently filed a consolidated class action complaint alleging violations of federal and California antitrust laws. Defendants filed a motion to dismiss, arguing that the consolidated complaint should be dismissed for the same reasons as the Texas-Ohio case. The court issued an order granting the motion to dismiss on December 19, 2005 and entered judgment in favor of defendants on December 23, 2005. Plaintiffs have appealed the dismissal to the Ninth Circuit Court of Appeals. California-based plaintiffs in the pending Ninth Circuit Court of Appeals cases (Texas-Ohio, Fairhaven, Abelman Art Glass and Utility Savings) have entered into a settlement agreement dated January 10, 2007 to collectively settle their claims against all CMS Energy defendants for the payment of $700,000. Plaintiffs filed a motion for preliminary approval of this and other settlements with various defendants on April 3, 2007. An order was entered on May 3, 2007 granting preliminary approval of the settlement, and CMS has wire transferred its $700,000 settlement payment.

CO-2


Commencing in or about February 2004, 15 state law complaints containing allegations similar to those made in the Texas-Ohio case, but generally limited to the California Cartwright Act and unjust enrichment, were filed in various California state courts against many of the same defendants named in the federal price manipulation cases discussed above. In addition to CMS Energy, CMS MST is named in all of the 15 state law complaints. Cantera Gas Company and Cantera Natural Gas, LLC (erroneously sued as Cantera Natural Gas, Inc.) are named in all but one complaint.
In February 2005, these 15 separate actions, as well as nine other similar actions that were filed in California state court but do not name CMS Energy or any of its former or current subsidiaries, were ordered coordinated with pending coordinated proceedings in the San Diego Superior Court. The 24 state court complaints involving price reporting were coordinated as Natural Gas Antitrust Cases V. Plaintiffs in Natural Gas Antitrust Cases V were ordered to file a consolidated complaint, but a consolidated complaint was filed only for the two putative class action lawsuits. Pursuant to a ruling dated August 23, 2006, CMS Energy, Cantera Gas Company and Cantera Natural Gas, LLC were dismissed as defendants in the master class action and the thirteen non-class actions, due to lack of personal jurisdiction. CMS MST remains a defendant in all of these actions. CMS MST has settled a master class action suit in California state court for $7 million. In March 2007, CMS Energy paid $7 million into a trust fund account following preliminary approval of the settlement by the judge. The settlement remains subject tocourt entered a judgment, final order and decree dated June 12, 2007 granting final approval pending notice to membersthe class action settlement with CMS MST. Certain of the class, who have an opportunity to opt out of or object toindividual cases filed in the settlement. California State Court remain pending.
Samuel D. Leggett, et al v. Duke Energy Corporation, et al, a class action complaint brought on behalf of retail and business purchasers of natural gas in Tennessee, was filed in the Chancery Court of Fayette County, Tennessee in January 2005. The complaint contains claims for violations of the Tennessee Trade Practices Act based upon allegations of false reporting of price information by defendants to publications that compile and publish indices of natural gas prices for various natural gas hubs. The complaint seeks statutory full consideration damages and attorneys fees and injunctive relief regulating defendants'defendants’ future conduct. The defendants include CMS Energy, CMS MST and CMS Field Services. On August 10, 2005, certain defendants, including CMS MST, filed a motion to dismiss and CMS Energy and CMS Field Services filed a motion to dismiss for lack of personal jurisdiction. Defendants attempted to remove the case to federal court, but it was remanded to state court by a federal judge. On February 2, 2007, the state court granted defendants'defendants’ motion to dismiss the complaint. Plaintiffs filed a notice of appeal on April 4, 2007.
J.P. Morgan Trust Company, in its capacity as Trustee of the FLI Liquidating Trust, filed an action in Kansas state court in August 2005 against a number of energy companies, including CMS Energy, CMS MST and CMS Field Services. The complaint alleges various claims under the Kansas Restraint of Trade Act relating to reporting false natural gas trade information to publications that report trade information. Plaintiff is seeking statutory full consideration damages for its purchases of natural gas between January 1, 2000 and December 31, 2001. The case was removed to the United States District Court for the District of Kansas on September 8, 2005 and transferred to the MDL proceeding on October 13, 2005. A motion to remand the case back to Kansas state court was denied on April 21, 2006. The court initially issued an order granting the motion to dismiss on December 18, 2006, but later reversed the ruling on reconsideration and entered judgment in favor of defendants on January 4, 2007. has now denied the defendants’ motion to dismiss.
On November 20, 2005, CMS MST was served with a summons and complaint which named CMS Energy, CMS MST and CMS Field Services as defendants in a putative class action filed in Kansas state court, Learjet, Inc., et al. v. Oneok, Inc., et al. Similar to the other actions that have been filed, the complaint alleges that during the putative class period, January 1, 2000 through October 31, 2002, defendants engaged in a scheme to violate the Kansas Restraint of Trade Act by knowingly reporting false or inaccurate information to the publications, thereby affecting the market price of natural gas. Plaintiffs,

CO-3


who allege they purchased natural gas from defendants and others for their facilities, are seeking statutory full consideration damages consisting of the full consideration paid by plaintiffs for natural gas. On December 7, 2005, the case was removed to the United States District Court for the District of Kansas and later that month a motion was filed to transfer the case to the MDL proceeding. On January 6, 2006, plaintiffs filed a motion to remand the case to Kansas state court. On January 23, 2006, a conditional transfer order transferring the case to the MDL proceeding was issued. On February 7, 2006, plaintiffs filed an opposition to the conditional transfer order.order and on June 20, 2006 the MDL Panel issued an order transferring the case to the MDL proceeding. The court issued an order dated August 3, 2006 denying the motion to remand the case to Kansas state court. Defendants have filed a motion to dismiss, which remains pending.
Breckenridge Brewery of Colorado, LLC and BBD Acquisition Co. v. Oneok, Inc., et al., a class action complaint brought on behalf of retail direct purchasers of natural gas in Colorado, was filed in Colorado state court in May 2006. Defendants, including CMS Energy, CMS Field Services, and CMS MST, are alleged to have violated the Colorado Antitrust Act of 1992 in connection with their natural gas price reporting activities. Plaintiffs are seeking full refund damages. The case was removed to the United States District Court for the District of Colorado on June 12, 2006, and a conditional transfer order transferring the case to the MDL proceeding was entered on June 27, 2006. Plaintiffs are seeking to have2006, and an order transferring the case remandedto the MDL proceeding was entered on October 17, 2006. The court issued an order dated December 4, 2006 denying the motion to remand the case back to Colorado state court. Defendants have filed a motion to dismiss, which remains pending.
On October 30, 2006, CMS Energy and CMS MST were each served with a summons and complaint which named CMS Energy, CMS MST and CMS Field Services as defendants in an action filed in Missouri state court, titled Missouri Public Service Commission v. Oneok, Inc. The Missouri Public Service Commission purportedly is acting as an assignee of six local distribution companies, and it alleges that from at least January 2000 through at least October 2002, defendants knowingly reported false natural gas prices to publications that compile and publish indices of natural gas prices, and engaged in wash sales. The complaint contains claims for violation of the Missouri Anti-Trust Law, fraud and unjust enrichment. Defendants removed the case to Missouri federal court and then transferred it to the Nevada MDL proceeding. A second action, Heartland Regional Medical Center, et al. v. Oneok, Inc., et al., was filed in Missouri state court in March 2007 alleging violations of Missouri anti-trust laws. The second action is denoted as a class action. Defendants also removed this case to Missouri federal court, and it has been conditionally transferred to the Nevada MDL proceeding.
A class action complaint, Arandell Corp., et al v. XCEL Energy Inc., et al, was filed on or about December 15, 2006 in Wisconsin state court on behalf of Wisconsin commercial entities that purchased natural gas between January 1, 2000 and October 31, 2002. Defendants, including CMS Energy, CMS ERM and Cantera Gas Company, LLC, are alleged to have violated Wisconsin'sWisconsin’s Anti-Trust statute by conspiring to manipulate natural gas prices. Plaintiffs are seeking full consideration damages, plus exemplary damages in an amount equal to three times the actual damages, and attorneys'attorneys’ fees. The action was removed to Wisconsin federal district court and CMS entered a special appearance for purpose of filing a motion to dismiss all the CMS defendants on the ground of lack of personal jurisdiction. The court denied plaintiffs’ motion to remand the case back to Wisconsin state court, and the case has been transferred to the Nevada MDL proceeding.
CMS Energy and the other CMS defendants will defend themselves vigorously against these matters but cannot predict their outcome.

QUICKSILVER RESOURCES, INC.
On November 1, 2001, Quicksilver sued CMS MST in the Texas State Court in Fort Worth, Texas for breach of contract in connection with a Base Contract for Sale and Purchase of natural gas, pursuant to which Quicksilver agreed to sell, and CMS MST agreed to buy, natural gas. Quicksilver contended that a special provision in the contract requires CMS MST to pay Quicksilver 50 percent of the difference between $2.47/MMBtu and the index price each month. CMS MST disagrees with Quicksilver'sQuicksilver’s interpretation of the special provision and contends that it has paid all monies owed for delivery of gas pursuant to the contract. Quicksilver is seeking damages of approximately $126 million, plus prejudgment interest and attorneys' fees, which in CMS Energy's judgment is unsupported by the facts. CO-4 The matter was tried before a jury inattorneys’ fees.
Trial commenced on March 19, 2007. The jury made a finding that CMS MST has breached the agreement withverdict awarded Quicksilver but found that Quicksilver had failed to prove damages and accordingly awarded zero compensatory damages to Quicksilver. However, the jury awardedbut $10 million in punitive damages against CMS MST.damages. The jury found that CMS MST will opposebreached the contract and committed fraud but found no actual damage on account of either such claim.
On May 15, 2007, the trial court, ruling on motions to counter the entry of the judgment, vacated the jury award of punitive damages onbut held that the basis that Texas law will not permit an awardcontract should be rescinded prospectively. The judicial rescission of punitive damages if no compensatory damages have been awarded.the contract caused CMS Energy to record a charge in the second quarter of 2007 of approximately $24 million, net of tax. To preserve its appellate rights, CMS MST filed a motion to modify, correct or reform the judgment and a motion for a judgment contrary to the jury verdict with the trial court. The trial court dismissed these motions. CMS MST has scheduledfiled a date in early May to consider motions to enter judgment bynotice of appeal with the opposing sidesTexas Court of the litigation.

CMS ENERGY AND CONSUMERS
SECURITIES CLASS ACTION LAWSUITS
Beginning in May 2002, a number of complaints were filed against CMS Energy, Consumers and certain officers and directors of CMS Energy and its affiliates in the United States District Court for the Eastern District of Michigan. The cases were consolidated into a single lawsuit (the "Shareholder Action"“Shareholder Action”), which generally seeks unspecified damages based on allegations that the defendants violated United States securities laws and regulations by making allegedly false and misleading statements about CMS Energy'sEnergy’s business and financial condition, particularly with respect to revenues and expenses recorded in connection with round-trip trading by CMS MST. In January 2005, the court granted a motion to dismiss Consumers and three of the individual defendants, but denied the motions to dismiss CMS Energy and the 13 remaining individual defendants. In March 2006, the court conditionally certified a class consisting of "all“all persons who purchased CMS Common Stock during the period of October 25, 2000 through and including May 17, 2002 and who were damaged thereby." The court excluded purchasers of CMS Energy'sEnergy’s 8.75 percent Adjustable Convertible Trust Securities ("ACTS"(“ACTS”) from the class and, in response, a new class action lawsuit was filed on behalf of ACTS purchasers (the "ACTS Action"“ACTS Action”) against the same defendants named in the Shareholder Action. The settlement described below,in the following paragraph, if approved, will resolve both the Shareholder and ACTS Actions.
On January 3, 2007, CMS Energy and other parties entered into a Memorandum of Understanding (the "MOU"“MOU”), subject to court approval, regarding settlement of the two class action lawsuits. The settlement was approved by a special committee of independent directors and by the full board of directors of CMS Energy. Both judged that it was in the best interests of shareholders to eliminate this business uncertainty. The MOU is expected to lead to a detailed stipulation of settlement that will be presented to the assigned federal judge and the affected class in the second quarter of 2007. Under the terms of the MOU, the litigation will be settled for a total of $200 million, including the cost of administering the settlement and any attorney fees the court awards. CMS Energy will make a payment of approximately $123 million plus an amount equivalent to interest on the outstanding unpaid settlement balance beginning on the date of preliminary approval ofby the court and

CO-5


running until the balance of the settlement funds is paid into a settlement account. Out of the total settlement, CMS Energy's insurers will pay approximately $77 million directly to the settlement account. CMS Energy took an approximately $123 million pre-tax charge to 2006 earnings in the fourth quarter of 2006. In entering into the MOU, CMS Energy makes no admission of liability under the Shareholder Action and the ACTS Action. The parties executed a Stipulation and Agreement of Settlement dated May 22, 2007 (“Stipulation”) incorporating the terms of the MOU. On May 30, 2007, plaintiffs filed a “Motion for Order Preliminarily Approving Stipulation and Agreement of Settlement.” On June 7, 2007, the court entered a “Preliminary Order in Connection with Settlement Proceedings and Proposed Class Certification,” in which the court preliminarily approved the Stipulation and scheduled the settlement fairness hearing for September 6, 2007. In accordance with the Stipulation, CMS has paid approximately $1 million of the settlement amount to fund administrative expenses. The remaining $199 million and interest accruing thereon from the date of the June 7, 2007 order is payable ten business days after entry of the Order and Final Judgment following the September 6, 2007 hearing.
ENVIRONMENTAL MATTERS
CMS Energy and Consumers, as well as their subsidiaries and affiliates are subject to various federal, state and local laws and regulations relating to the environment. Several of these companies have been named parties to various actions involving environmental issues. Based on their present knowledge and subject to future legal and factual developments, they believe it is unlikely that these actions, individually or in total, will have a material adverse effect on their financial condition or future results of operations.

Risks Related to CMS Energy has recently completed asset sales of substantially all of its international assets. Its remaining international assets located in Argentina, Chile and Jamaica are subject to sale that is expected toConsumers
CMS Energy and Consumers may be completed later this year. Therefore, CMS Energy's international exposure is reduced significantly. RISKS RELATED TO CMS ENERGY AND CONSUMERS CMS ENERGY AND CONSUMERS MAY BE ADVERSELY AFFECTED BY REGULATORY INVESTIGATIONS REGARDING "ROUND-TRIP" TRADING BYadversely affected by regulatory investigations regarding “round-trip” trading by CMS MST AS WELL AS CIVIL LAWSUITS REGARDING PRICING INFORMATION THATas well as civil lawsuits regarding pricing information that CMS MST ANDand CMS FIELD SERVICES PROVIDED TO MARKET PUBLICATIONS. Field Services provided to market publications.
As a result of round-trip trading transactions (simultaneous, prearranged commodity trading transactions in which energy commodities were sold and repurchased at the same price) at CMS MST, CMS Energy is under investigation by the DOJ. CMS Energy received subpoenas in 2002 and 2003 from U.S. Attorneys'Attorneys’ Offices regarding investigations of those trades. CMS Energy responded to those subpoenas in 2003 and 2004.
In March 2004, the SEC approved a cease-and-desist order settling an administrative action against CMS Energy relating to round-trip trading. The order did not assess a fine and CMS Energy neither admitted nor denied the order'sorder’s findings.
CMS Energy has notified appropriate regulatory and governmental agencies that some employees at CMS MST and CMS Field Services appeared to have provided inaccurate information regarding natural gas trades to various energy industry publications which compile and report index prices. CMS Energy is cooperatinghas cooperated with an ongoing investigation by the DOJ regarding this matter. Although CMS Energy has not received any formal notification that the DOJ has completed its investigation, the DOJ’s last request for

CO-6


information occurred in November 2003, and CMS Energy completed its response to this request in May 2004. CMS Energy is unable to predict the outcome of the DOJ investigation and what effect, if any, the investigation will have on CMS Energy. The CFTC filed a civil injunctive action against two former CMS Field Services employees in Oklahoma federal district court on February 1, 2005. The action alleges the two engaged in reporting false natural gas trade information, and seeks to enjoin these acts, compel compliance with the Commodities Exchange Act, and impose monetary penalties. Trial dates have been held in abeyance pending settlement discussions. CMS Energy is currently advancing legal defense costs to the two individuals in accordance with existing indemnification policies. CO-6 The court entered separate consent orders with respect to each of the two individuals, one dated April 18, 2007 and one dated June 25, 2007, resolving this litigation. The consent orders enjoin each of the individuals from engaging in certain activities and further provide civil monetary penalties in the amount of $100,000 for one individual and $25,000 for the other individual. Pursuant to agreements with each of the individuals, CMS has paid $95,000 of the $100,000 amount and $22,000 of the $25,000 amount, with the remaining amounts paid by the individuals themselves. These settlements put an end to CFTC enforcement actions relating to gas price reporting by individuals once employed at present or former CMS subsidiaries.
CMS Energy, CMS MST, CMS Field Services, Cantera Natural Gas, Inc. (the company that purchased CMS Field Services) and Cantera Gas Company are named as defendants in various lawsuits arising as a result of false natural gas price reporting. Allegations include manipulation of NYMEX natural gas futures and options prices, price-fixing conspiracies, and artificial inflation of natural gas retail prices in California, Colorado, Kansas, Missouri, Tennessee, and Wisconsin. In September 2006, CMS MST reached an agreement in principle to settle a master class action suit in California for $7 million, pending approval by the trial Court. The court entered an order granting preliminary approval of the settlement, and CMS MST has paid the $7 million settlement amount. The court entered a judgment, final order and decree dated June 12, 2007 granting final approval to the class action settlement with CMS MST.
CMS Energy and the other CMS Energy defendants will defend themselves vigorously against all of these matters, but cannot predict the outcome of the DOJ investigations and the lawsuits. It is possible that the outcome in one or more of the investigations or the lawsuits could adversely affect CMS Energy'sEnergy’s and Consumers'Consumers’ financial condition, liquidity or results of operations.
CMS ENERGY AND CONSUMERS COULD INCUR SIGNIFICANT CAPITAL EXPENDITURES TO COMPLY WITH ENVIRONMENTAL STANDARDS AND FACE DIFFICULTY IN RECOVERING THESE COSTS ON A CURRENT BASIS. Energy and Consumers could incur significant capital expenditures to comply with environmental standards and face difficulty in recovering these costs on a current basis.
CMS Energy, Consumers, and their subsidiaries are subject to costly and increasingly stringent environmental regulations. They expect that the cost of future environmental compliance, especially compliance with clean air and water laws, will be significant.
In 1998, the EPA issued regulations requiring the State of Michigan to further limit nitrogen oxide emissions at coal-fired electric generating plants. The EPA and State of Michigan regulations require Consumers to make significant capital expenditures estimated to be $835 million. As of March 2007,From 1998 to present, Consumers has incurred $760$782 million in capital expenditures to comply with these regulations and anticipates that the remaining $75$53 million of capital expenditures will be made in 2007 through 2011. In addition to modifying coal-fired electric plants, Consumers'Consumers’ compliance plan includes the use of nitrogen oxide emission allowances until all of the control equipment is operational in 2011. The nitrogen oxide emission allowance annual expense is projected to be $3$2 million per year, which Consumers expects to recover from customers through the PSCR process.
In March 2005, the EPA adopted the Clean Air Interstate Rule that requires additional coal-fired electric plant emission controls for nitrogen oxides and sulfur dioxide. Consumers plans to meet the nitrogen

CO-7


oxide requirements of this rule by year-round operation of its selective catalytic reduction control technology units, installation of low nitrogen oxide burners, and purchasing emission allowances. Consumers plans to meet the sulfur dioxide requirements of this rule using sorbent injection, installation of flue gas desulfurization scrubbers and purchasing emission allowances. Consumers'Consumers’ total cost for equipment installation is expected to reach approximately $700 million by 2015. Additional purchases of sulfur dioxide emission allowances in 2012 and 2013 will be needed for an estimated cost of $12 million per year, which Consumers expects to recover from customers through the PSCR process.
The Clean Air Interstate Rule was appealed to the U.S. Court of Appeals for the District of Columbia by a number of utilities and other companies. Final briefs are due September 5, 2007, with a decision expected in 2008. We cannot predict the outcome of these appeals.
Also in March 2005, the EPA issued the Clean Air Mercury Rule, which requires initial reductions of mercury emissions from coal-fired electric generating plants by 2010 and further reductions by 2018. The Clean Air Mercury Rule was appealed to the U.S. Court of Appeals by a number of states and other entities. Final briefs are due July 13, 2007, with a decision expected in 2008. We cannot predict the outcome of these appeals.
In April 2006, Michigan'sMichigan’s governor announced a plan that would result in mercury emissions reductions of 90 percent by 2015. Consumers is currently working with the MDEQ on the details of these rules; however, Consumers has developed preliminary cost estimates and a mercury emissions reduction planscenario based on its best knowledge of control technology options and anticipatedinitially proposed requirements. Consumers' planThe scenario includes expenditures of close to $550approximately $541 million for mercury control equipment and continuous emissions monitoring systems through 2014. CO-7
The EPA has alleged that some utilities have incorrectly classified plant modifications as “routine maintenance” rather than seeking permits from the EPA to modify the plant. We have received and responded to information requests from the EPA on this subject. We believe that we have properly interpreted the requirements of “routine maintenance.” If our interpretation is found to be incorrect, we may be required to install additional pollution controls at some or all of our coal-fired electric generating plants and potentially pay fines. Additionally, the viability of certain plants remaining in operation could be called into question.
Several legislative proposals have been introduced in the United States Congress that would require reductions in emissions of greenhouse gases, including carbon dioxide. CMS Energy and Consumers cannot predict whether any of these proposals will be enacted, or the specific requirements of any of these proposals and their effect on future operations and financial results. On April 2, 2007, the U.S. Supreme Court ruled that the Clean Air Act gives the EPA the authority to regulate emissions of carbon dioxide and other greenhouse gases from automobiles. In its decision, the court ordered the EPA to revisit its contention that it has the discretion not to regulate greenhouse gas emissions from automobiles.
To the extent that greenhouse gas emission reduction rules come into effect, the mandatory emissions reduction requirements could have far-reaching and significant implications for the energy sector. CMS Energy and ConsumersWe cannot estimate the potential effect of federal or state greenhouse gas policy on theirour future consolidated results of operations, cash flows, or financial position due to the uncertain nature of the policies at this time. However, CMS Energy and Consumerswe will continue to monitor greenhouse gas policy developments and assess and respond to their potential implications on theirour business operations.
In March 2004, the EPA issued rules that govern electric generating plant cooling water intake systems. The rules require significant reduction in fish killed by operating equipment. EPA compliance options in the rule were challenged in court. In January 2007, the court rejected many of the compliance options favored by industry and remanded the bulk of the rule back to the EPA for reconsideration. The court'scourt’s ruling is expected to increase significantly the cost of complying with this rule. However, the cost to

CO-8


comply will not be known until the EPA'sEPA’s reconsideration is complete. At this time, the EPA has not established a schedule to address the court decision.
CMS Energy expects to collect fully from its customers, through the ratemaking process, these and other required environmental expenditures. However, if these expenditures are not recovered from customers in Consumers'Consumers’ rates, CMS Energy and/or Consumers may be required to seek significant additional financing to fund these expenditures, which could strain their cash resources.
