MANAGEMENT’S DISCUSSION AND ANALYSIS

This MD&A is a combined report of CMS Energy and Consumers. It 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 MD&A contained in the 2009 Form 10-K.

EXECUTIVE OVERVIEW

CMS Energy is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including Consumers, an electric and gas utility, and CMS Enterprises, primarily a domestic IPP. Consumers’ electric utility operations include the generation, purchase, distribution, and sale of electricity and Consumers’ gas utility operations include the purchase, transmission, storage, distribution, and sale of natural gas. Consumers’ customer base consists of a mix of residential, commercial, and diversified industrial customers. CMS Enterprises, through its subsidiaries and equity investments, owns power generation facilities.

CMS Energy and Consumers manage their businesses by the nature of services each provides. CMS Energy operates principally in three business segments: electric utility; gas utility; and enterprises, its non-utility investments and operations. Consumers operates principally in two business segments: electric utility and gas utility.

CMS Energy and Consumers earn revenue and generate cash from operations by providing electric and natural gas utility services, electric distribution and generation, gas transmission, storage, and distribution, and other energy-related services. Their businesses are affected primarily by:

	•		regulation and regulatory matters;

	•		economic conditions;

	•		weather;

	•		energy commodity prices;

	•		interest rates; and

	•		CMS Energy’s and Consumers’ securities credit ratings.

During the past several years, CMS Energy’s business strategy has emphasized improving its consolidated balance sheet and maintaining focus on its core strength, which is Consumers’ utility operations and service.

In August 2010, CMS Energy announced that it would reduce its planned capital investments by $1 billion over the next five years, which will moderate future rate increases to Consumers’ customers. Consumers still expects to make capital investments of more than $6 billion over the next five years, with a key aspect of its strategy being the balanced energy initiative. The balanced energy initiative is a comprehensive energy resource plan to meet Consumers’ projected short-term and long-term electric power requirements with energy efficiency; demand management; expanded use of renewable energy; development of new power plants; pursuit of additional PPAs to complement existing generating sources; potential retirement or mothballing of older generating units; and continued operation of others.

developments in shale gas recovery technology, and projected surplus generating capacity in the MISO market. Consumers has not set a timetable for a future decision about the project.

Consumers’ planned capital investments continue to include renewable energy projects. Consumers expects to spend $650 million on renewable energy investments through 2014. The 2008 Energy Legislation requires that at least ten percent of Consumers’ electric sales volume come from renewable energy sources by 2015, and includes requirements for specific capacity additions. In compliance with this legislation, Consumers filed a renewable energy plan with the MPSC in February 2009 outlining its plans to build or contract for additional renewable energy capacity. At the same time, Consumers filed an energy optimization plan, also called for by the 2008 Energy Legislation, under which Consumers will promote energy efficiency and provide incentives to reduce customer usage. In May 2009, the MPSC approved the energy optimization plan and, with minor exceptions, the renewable energy plan. As one of the conditions to the continuation of the electric and gas pilot decoupling mechanisms that were adopted in general rate cases, Consumers must exceed the statutory savings targets specified in the 2008 Energy Legislation for 2011 through 2014. In September 2010, Consumers filed an amended energy optimization plan to recover the additional spending necessary to exceed these savings targets.

Consumers also intends to make a significant capital investment in its smart grid program, which should provide enhanced controls over, and information about, energy usage, as well as timely notification of service interruptions. Consumers plans to follow a phased implementation approach and intends to begin deployment of meters in early 2012.

Regulatory matters are a key aspect of CMS Energy’s and Consumers’ businesses, particularly Consumers’ rate cases and regulatory proceedings before the MPSC. In February 2010, the MPSC issued an order requiring that Consumers refund to customers $85 million collected during a rate freeze from 2001 to 2003 plus interest; the MPSC determined that these funds should have been placed in a decommissioning trust fund. Consumers has filed an appeal of this order. In May 2010, the MPSC issued a gas rate order authorizing Consumers to increase its gas rates by $66 million based on an authorized return on equity of 10.55 percent.

The May 2010 gas rate order also adopted a revenue decoupling mechanism. In general, a decoupling mechanism allows a utility to adjust rates due to changes in sales volumes, in order to improve the match between the collection of revenues and the revenue level approved by the utility’s regulator. Consumers’ gas decoupling mechanism, subject to certain conditions, allows Consumers to adjust future gas rates to compensate for changes in sales volumes resulting from energy efficiency, conservation, and other non-weather factors. Consumers’ electric decoupling mechanism, adopted in a November 2009 electric rate order, is similar to the gas decoupling mechanism, but also permits rate adjustments to compensate for changes in sales volumes resulting from weather fluctuations. For additional details regarding Consumers’ electric and gas decoupling mechanisms, see the “Outlook - Consumers’ Electric Utility Business Outlook and Uncertainties - Electric Customer Deliveries and Revenue” and the “Outlook - Consumers’ Gas Utility Business Outlook and Uncertainties - Gas Deliveries” sections included in MD&A.

Further, in July 2010, Consumers self-implemented an electric rate increase in the annual amount of $150 million, subject to refund with interest. In August 2010, Consumers filed an application with the MPSC seeking an annual gas rate increase of $55 million based on an 11 percent authorized return on equity. The filing requested recovery for investments made to enhance safety, system reliability, and operational efficiencies that improve service to customers. In its order allowing Consumers to self-implement the July 2010 electric rate increase, the MPSC expressed concern about utilities repeatedly self-implementing rate increases over short time periods, and before the return of previous overcollections of self-implemented rate increases.

The Customer Choice Act allows Consumers’ electric customers to buy electric generation service from Consumers or from alternative electric suppliers. The 2008 Energy Legislation limits alternative electric supply to ten percent of Consumers’ weather-adjusted retail sales of the preceding calendar year. In May 2010, a bill was introduced to the Michigan Senate and House of Representatives that would increase the limit from ten percent to 25 percent. At September 30, 2010, electric deliveries under the ROA program were at the ten percent limit.

Another area of importance for CMS Energy and Consumers is environmental regulation. There is uncertainty associated with federal legislative and regulatory proposals related to the regulation of carbon dioxide emissions, particularly associated with fossil-fueled generation. In December 2009, the EPA issued an endangerment finding that greenhouse gases, including carbon dioxide, contribute to air pollution that may endanger the public health and welfare, thus setting the stage for regulation of carbon dioxide emissions under the Clean Air Act. The EPA also issued an Advance Notice of Proposed Rulemaking in April 2010, indicating that it is considering a variety of regulatory actions with respect to PCBs. In June 2010, the EPA proposed a range of alternatives for regulating CCBs, such as coal ash, under the Resource Conservation and Recovery Act. In July 2010, the EPA released CATR, a proposed

rule that would replace CAIR. CMS Energy and Consumers are monitoring these developments for potential effects on their plans and operations.

CMS Energy will continue to focus its strategy on:

	•		investing in Consumers’ utility system;

	•		growing earnings and operating cash flow while controlling operating and fuel costs; and

	•		maintaining principles of safe, efficient operations, customer value, fair and timely regulation, and consistent financial performance.

In executing this strategy, CMS Energy and Consumers will need to overcome a Michigan economy that has been impacted adversely by the financial market crisis, uncertainty in Michigan’s automotive industry, high unemployment rates, and a modestly shrinking population. Due to the uncertain progress of economic recovery in Consumers’ service territory, a range of outcomes of CMS Energy’s and Consumers’ strategies are possible. Pressure on regulators to limit rate increases can be expected to mount if Michigan’s economy remains sluggish. Consumers expects that the electric and gas pilot decoupling mechanisms, as well as the electric utility’s uncollectible expense tracking mechanism, will mitigate partially the impacts of these economic conditions on the electric and gas utilities. While CMS Energy and Consumers believe that their sources of liquidity will be sufficient to meet their requirements, they will continue to monitor developments in the financial and credit markets, as well as government policy responses to those developments, for potential implications for CMS Energy’s and Consumers’ businesses and their future financial needs.

Electric deliveries and rate increases: For the three months ended September 30, 2010, electric delivery revenues increased $85 million compared with 2009. The increase was due to $31 million of additional revenues resulting from the July 2010 self-implemented rate increase. Also contributing to the increase was $54 million from higher deliveries, which included the impact of favorable weather in 2010 and increased deliveries in 2010 to Consumers’ high-margin customers, offset partially by the impact of customers switching from demand rates to energy-only rates. These increases were offset partially by a $16 million decrease in revenues resulting from other rate-related items, including the impacts of the decoupling mechanism that became effective in December 2009. Overall, deliveries to end-use customers were 10.5 billion kWh, an increase of 1.2 billion kWh or 12.9 percent compared with 2009.

Additionally, surcharge revenues and related reserves increased $16 million for the three months ended September 30, 2010 compared with 2009. This increase comprised $6 million from the collection of regulatory assets related to retirement benefits, a $5 million increase related to the energy optimization program, and a $5 million increase in other surcharge revenue.

For the nine months ended September 30, 2010, electric delivery revenues increased $186 million compared with 2009. The increase was due to $46 million of additional revenues resulting from the November 2009 rate order that Consumers self-implemented in May 2009, and $31 million of additional revenues resulting from the July 2010 self-implemented rate increase. Also contributing to the increase was $36 million from higher deliveries, which included the impact of favorable weather in 2010 and increased deliveries to Consumers’ high-margin customers, offset partially by the impact of customers switching from demand rates to energy-only rates. The increase was also due to $13 million of additional revenues resulting from other rate-related items, including the impacts of the decoupling mechanism that became effective in December 2009. Overall, deliveries to end-use customers were 28.6 billion kWh, an increase of 1.9 billion kWh or 7.1 percent compared with 2009.

Additionally, surcharge revenues and related reserves increased $60 million for the nine months ended September 30, 2010 compared with 2009. This increase comprised $32 million from the collection of regulatory assets related to retirement benefits, a $19 million increase related to the energy optimization program, and a $9 million increase in other surcharge revenue.

Power supply costs and related revenue: For the nine months ended September 30, 2010, PSCR revenue decreased $11 million compared with 2009, reflecting an order received from the MPSC that disallowed recovery of certain power supply costs in Consumers’ 2007 PSCR reconciliation case.

Other income, net of expenses: For the three months ended September 30, 2010, other income decreased $8 million compared with 2009, and for the nine months ended September 30, 2010, other income decreased $16 million compared with 2009. These decreases were due to a reduction in interest income recorded on certain regulatory assets and the absence in 2010 of a gain recognized on a sale of land in 2009.

Maintenance and other operating expenses: For the three months ended September 30, 2010, maintenance and other operating expenses increased $5 million compared with 2009. The increase was due to $6 million of higher retirement benefits expenses, which were recovered in revenue in 2010, a $5 million increase associated with the energy optimization program, and a $3 million increase in service restoration expenses. These increases were offset partially by a $5 million reduction in expenses for forestry and tree-trimming services and a $4 million decrease in health care expenses and other net operating expenses.

For the nine months ended September 30, 2010, maintenance and other operating expenses increased $39 million compared with 2009. The increase was due to $32 million of higher retirement benefits expenses, which were recovered in revenue in 2010, a $19 million increase associated with the energy optimization program, and an $8 million increase in uncollectible accounts expense. Also contributing to the increase was $6 million of voluntary separation plan expenses in 2010. These increases were offset partially by an $11 million reduction in expenses for forestry and tree-trimming services and a $15 million decrease in health care expenses and other net operating expenses.

Depreciation and amortization: For the three months ended September 30, 2010, depreciation and amortization expense increased $8 million compared with 2009, and for the nine months ended September 30, 2010, depreciation and amortization expense increased $20 million compared with 2009, due to increased plant in service and higher amortization expense on certain regulatory assets.

General taxes: For the three months ended September 30, 2010, general taxes decreased $3 million compared with 2009, due to lower property tax expense in 2010.

For the nine months ended September 30, 2010, general taxes decreased $3 million compared with 2009. The decrease resulted from adjustments associated with the State of Michigan’s use tax assessment.

Interest charges: For the three months ended September 30, 2010, interest charges decreased $3 million compared with 2009, due to lower debt levels in 2010.

For the nine months ended September 30, 2010, interest charges increased $3 million compared with 2009. The increase resulted from interest related to the State of Michigan’s use tax assessment. Also contributing to the increase was additional interest incurred as a result of an order received from the MPSC that disallowed recovery of certain power supply costs in Consumers’ 2007 PSCR reconciliation case. These increases were offset partially by lower debt levels in 2010.

Income taxes: For the three months ended September 30, 2010, income taxes increased $25 million compared with 2009. The increase reflected $28 million due to higher electric utility earnings, offset partially by a $3 million benefit related to research tax credits.

For the nine months ended September 30, 2010, income taxes increased $34 million compared with 2009. The increase reflected $37 million due to higher electric utility earnings, offset partially by a $3 million benefit related to research tax credits.

Gas deliveries and rate increases: For the three months ended September 30, 2010, gas delivery revenues increased $14 million compared with 2009, due to the May 2010 rate order. Gas deliveries, including miscellaneous transportation to end-use customers, were 25.3 bcf, an increase of 0.7 bcf or 2.8 percent compared with 2009.

For the nine months ended September 30, 2010, gas delivery revenues increased $33 million compared with 2009. The increase was due to $44 million of additional revenue resulting from the May 2010 rate order that Consumers self-implemented in November 2009, and $7 million from a favorable sales mix. These increases were offset partially by a decrease of $34 million due to lower deliveries associated with milder weather in 2010. Gas deliveries, including miscellaneous transportation to end-use customers, were 181.2 bcf, a decrease of 14.9 bcf or 7.6 percent compared with 2009.

Additionally, surcharge revenues were $16 million higher for the nine months ended September 30, 2010, due to a $13 million increase related to the energy optimization program and $3 million from the collection of regulatory assets related to retirement benefits.

Other income, net of expenses: For the nine months ended September 30, 2010, other income increased $4 million compared with 2009, due to higher interest income related to secured borrowing agreements.

Maintenance and other operating expenses: For the three months ended September 30, 2010, maintenance and other operating expenses decreased $1 million compared with 2009, due to lower health care expenses in 2010.

For the nine months ended September 30, 2010, maintenance and other operating expenses increased $8 million compared with 2009. The increase was due to additional expenses of $13 million related to the energy optimization program and $4 million of voluntary separation plan expenses. Also contributing to the increase were higher expenses of $3 million associated with retirement benefits, which were recovered in revenue in 2010. These increases were offset partially by lower uncollectible accounts expense of $2 million and a $10 million reduction in health care expenses and other transmission and distribution operating expenses.

General taxes: For the three months ended September 30, 2010, general taxes decreased $1 million compared with 2009, due to lower property tax expense in 2010.

Interest charges: For the nine months ended September 30, 2010, interest charges increased $7 million compared with 2009, due primarily to interest related to the State of Michigan’s use tax assessment.

Income taxes: For the three months ended September 30, 2010, income taxes increased $3 million compared with 2009, and for the nine months ended September 30, 2010, income taxes increased $8 million compared with 2009, due primarily to higher gas utility earnings.

For the three months ended September 30, 2010, the enterprises segment reported net income of $9 million compared with $6 million for the same period in 2009. The $3 million increase was due to the recognition of a gain on an option related to the 2007 sale of certain Argentine investments, and to lower expenses.

For the nine months ended September 30, 2010, the enterprises segment reported net income of $51 million compared with a net loss of $6 million for the same period in 2009. The $57 million change reflected after-tax income of $30 million from the settlement of an insurance claim related to a previously sold South American investment, the absence of an environmental remediation charge of $22 million recorded in 2009 related to Bay Harbor, and $4 million related to asset sales. An additional increase of $1 million reflected greater demand for power at higher prices and a net increase in mark-to-market gains, offset largely by higher maintenance and other operating expenses, the absence of a gain recorded in 2009 on the expiration of an indemnity provided in connection with a previous asset sale, and the absence of benefits related to a 2009 legal settlement associated with a gas sale and purchase contract.

For the three months ended September 30, 2010, corporate interest and other net expenses decreased $4 million compared with 2009, due to the absence of an $11 million premium paid in 2009 on the early retirement of debt and due to a $3 million benefit from higher net earnings at EnerBank and lower expenses. These items were offset partially by an $8 million charge for deferred issuance costs on the mandatory conversion of convertible preferred stock and by a $2 million increase in interest expense due to higher debt levels at higher average interest rates.

For the nine months ended September 30, 2010, corporate interest and other net expenses increased $13 million compared with 2009, due to the absence of an $18 million gain recognized in 2009 on the early retirement of long-term debt, related parties. Also contributing to the change was an $8 million charge for deferred issuance costs on the mandatory conversion of convertible preferred stock and a $6 million increase in interest expense due to higher debt levels at higher average interest rates. These items were offset partially by the absence of an $11 million premium paid in 2009 on the early retirement of debt and by an $8 million benefit from higher net earnings at EnerBank and lower expenses.

Discontinued Operations

For the three months ended September 30, 2010, the net loss from discontinued operations was less than $1 million. Discontinued operations recorded a loss of $1 million in 2009 due primarily to unfavorable operating results of assets held for sale.

For the nine months ended September 30, 2010, a loss of $17 million was recorded from discontinued operations, compared with income of $23 million in 2009. The $40 million change was due to the absence of a $28 million gain recognized in 2009 on the expiration of an indemnity provided in connection with a 2007 asset sale, the recognition in 2010 of $10 million in additional tax expense resulting from an IRS audit adjustment related to a 2003 asset sale, and a $3 million increase in a liability for a 2007 asset sale indemnity. These decreases were offset slightly by lower losses in 2010 related primarily to assets held for sale.

CMS Energy and Consumers believe that their present level of cash and their expected cash flows from operating activities, together with their access to sources of liquidity, will be sufficient to meet cash requirements. If access to the capital markets were to become diminished or otherwise restricted, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending. For additional details, see Note 5, Financings.

In March 2010, CMS Energy contributed $100 million to its pension fund, which included a contribution of $97 million by Consumers. Actual future pension cost and contributions will depend on future investment performance, changes in discount rates, and various other factors related to the Pension Plan participants.

In April 2010, Consumers reached an agreement with the Union on a new five-year contract for operating, maintenance, and construction employees. The agreement changed postretirement health benefits under the OPEB plan for qualifying retired employees. As a result, CMS Energy and Consumers remeasured their OPEB obligations at April 30, 2010.

Off-Balance-Sheet Arrangements

CMS Energy, Consumers, and certain of their subsidiaries enter into various arrangements in the normal course of business to facilitate commercial transactions with third parties. These arrangements include indemnities, surety bonds, letters of credit, and financial and performance guarantees. Indemnities are usually agreements to reimburse a counterparty that may incur losses due to outside claims or breach of contract terms. The maximum payment that could be required under a number of these indemnity obligations is not estimable. While CMS Energy and Consumers believe it is unlikely that they will incur any material losses related to indemnities they have not recorded as liabilities, they cannot predict the impact of these contingent obligations on their liquidity and financial condition. For additional

details on these and other guarantee arrangements, see Note 3, Contingencies and Commitments, “Guarantees.”

OUTLOOK

Several business trends and uncertainties may affect CMS Energy’s and Consumers’ financial condition and results of operations. These trends and uncertainties could have a material impact on CMS Energy’s and Consumers’ consolidated income, cash flows, or financial position. For additional details regarding these and other uncertainties, see “Forward-Looking Statements and Information,” Note 3, Contingencies and Commitments, and Part II, Item 1A. Risk Factors.

Consumers’ Electric Utility Business Outlook and Uncertainties

Balanced Energy Initiative: Consumers’ balanced energy initiative is a comprehensive energy resource plan designed to meet its projected short-term and long-term electric power requirements through:

	•		energy efficiency;

	•		demand management;

	•		expanded use of renewable energy;

	•		development of new power plants and pursuit of additional PPAs to complement existing generating sources; and

	•		potential retirement or mothballing of older generating units.

In May 2010, Consumers announced plans to defer the development of its proposed 830 MW coal-fueled plant at its Karn/Weadock generating complex. This decision reflects reduced customer demand for electricity due to the recession, forecasted lower natural gas prices due to recent developments in shale gas recovery technology, and projected surplus generating capacity in the MISO market. Consumers will monitor customer demand, fuel and power prices, and other market conditions, but has not set a timetable for a future decision about the project. Consumers’ alternatives to constructing the proposed coal-fueled plant include constructing new gas-fueled generation, relying on additional market purchases, as well as continued operation of several existing generating units; however, Consumers continues to believe that new clean coal generating capacity will be in the long-term best interests of its customers as part of a balanced energy portfolio.

Renewable Energy Plan: Consumers’ renewable energy plan details how Consumers will meet REC and capacity standards prescribed by the 2008 Energy Legislation. This legislation requires Consumers to obtain RECs in an amount equal to at least ten percent of its electric sales volume (estimated to be 3.6 million RECs annually) by 2015. RECs represent proof that the associated electricity was generated from a renewable energy resource. The legislation also requires Consumers to obtain 500 MW of capacity from renewable energy resources by 2015, either through generation resources owned by Consumers or through agreements to purchase capacity from other parties.

Under its renewable energy plan, Consumers expects to secure its required RECs each year with a combination of newly generated RECs and previously generated RECs carried over from prior years. Presently, Consumers generates and purchases 1.6 million RECs per year, which represent 44 percent of its long-term REC needs.

To meet its renewable capacity requirements, Consumers expects to add 500 MW of owned or contracted renewable capacity by 2015. Consumers has secured more than 78,000 acres of land easements in Michigan’s Mason, Huron, and Tuscola Counties for the potential development of wind generation, and is presently collecting wind speed and other meteorological data at those sites. Consumers has entered into a contract to purchase wind turbine generators for the construction of a 100 MW wind farm in Mason County, the Lake Winds Energy Park, which Consumers expects to be operational in late 2012. Consumers will continue to seek opportunities for wind generation development in support of the renewable capacity standards.

In June 2010, Consumers executed agreements with four renewable energy suppliers for the purchase of 243 MW of capacity. In its July 2010 order, the MPSC approved these agreements, granting Consumers’ request to recover the full costs of these contracts from its customers.

Electric Customer Deliveries and Revenue: Consumers’ electric customer deliveries are largely dependent on Michigan’s economy, which has suffered from economic and financial instability in the automotive and real estate sectors.

Consumers expects weather-adjusted electric deliveries to increase in 2010 by 1.5 percent compared with 2009. Consumers’ outlook for 2010 includes continuing growth in deliveries to its largest customer, which produces energy-related components. Consumers has a long-term contract with this customer to provide electricity at a discounted rate for economic development purposes. Excluding this customer’s growth, Consumers expects weather-adjusted electric deliveries in 2010 to be at a similar level to 2009. Consumers’ outlook reflects the impact of reduced deliveries associated with its investment in energy efficiency programs included in the 2008 Energy Legislation, as well as recent projections of Michigan’s economic conditions.

Consumers believes economic conditions have stabilized. Consumers’ present outlook for electric delivery growth is about two percent on average through 2015. This reflects growth in electric deliveries offset by the predicted effects of energy efficiency programs and appliance efficiency standards. Actual deliveries will depend on:

	•		energy conservation measures and results of energy efficiency programs;

	•		fluctuations in weather; and

	•		changes in economic conditions, including utilization and expansion or contraction of manufacturing facilities, population trends, and housing activity.

In its 2009 electric rate case order, the MPSC authorized Consumers to adopt a pilot decoupling mechanism. This mechanism, subject to certain conditions, allows Consumers to adjust future rates to collect or refund the change in marginal revenue by class arising from the difference between the level of average sales per customer adopted in the order and actual average sales per customer. The MPSC’s order also adopted an uncollectible expense tracking mechanism, which allows future rates to be adjusted to collect or refund 80 percent of the difference between the level of uncollectible expense included in rates and actual uncollectible expense. Consumers expects these mechanisms to reduce volatility of electric utility revenue.

Electric ROA: The Customer Choice Act allows Consumers’ electric customers to buy electric generation service from Consumers or from an alternative electric supplier. The 2008 Energy Legislation limits alternative electric supply to ten percent of Consumers’ weather-adjusted retail sales of the preceding calendar year. At September 30, 2010, electric deliveries under the ROA program were at the ten percent limit and alternative electric suppliers were providing 800 MW of generation service to ROA customers.

In May 2010, a bill was introduced to the Michigan Senate and House of Representatives that would increase from ten percent to 25 percent the proportion of an electric utility’s sales for which service may be provided by an alternative electric supplier. Consumers is unable to predict the outcome of the proposed legislation.

Electric Environmental Estimates: Consumers’ operations are subject to various state and federal environmental laws and regulations. Consumers continues to focus on complying with the Clean Air Act, Clean Water Act, and numerous state and federal environmental regulations. Consumers estimates that it will incur expenditures of $1.9 billion from 2010 through 2017 to comply with these regulations. Consumers expects to recover these costs in customer rates, but cannot guarantee this result. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters:

Clean Air Interstate Rule/Clean Air Transport Rule: At this time, CAIR remains in effect, pending the EPA’s finalization of a new rule due to a December 2008 court decision that remanded CAIR back to the EPA. In July 2010, the EPA released CATR, a proposed rule that would replace CAIR. Consumers is examining this proposed rule, its potential effects on Consumers’ fossil-fueled power plants, and potential compliance strategies. If adopted in its present form, CATR could result in additional or accelerated environmental compliance costs related to Consumers’ fossil-fueled power plants. In addition, Consumers is monitoring legislative initiatives in the U.S. Senate, which may affect CAIR and CATR. Presently, Consumers’ strategy to comply with CAIR involves the installation of state-of-the-art emission control equipment.

Federal Hazardous Air Pollutant Regulation: The EPA is developing Maximum Achievable Control Technology emission standards for electric generating units, based on Section 112 of the Clean Air Act. Consumers is unable to predict the impact of the proposed rule, but expects to have a better understanding of the potential impact upon release of the proposed rule, which is expected in March 2011. Existing sources must meet the standards generally within three years of issuance of the final rule. The final rule is expected to be issued in November 2011.

Greenhouse Gases: There are numerous legislative and regulatory initiatives at the state, regional, and national levels that involve the regulation of greenhouse gases. Consumers monitors and comments on these initiatives and also follows litigation involving greenhouse gases. Consumers believes Congress may eventually pass greenhouse gas legislation, but is unable to predict the form and timing of any final legislation.

In December 2009, the EPA issued an endangerment finding for greenhouse gases under the Clean Air Act. In this finding, which has been challenged in the U.S. Court of Appeals for the D.C. Circuit by numerous parties, the EPA determined that current and projected atmospheric concentrations of six greenhouse gases threaten the public health and welfare of current and future generations. The finding alone does not impose any standard or regulation on industry, but it is a precursor for finalizing proposed emissions standards. In April 2010, the EPA issued its final rule that regulates greenhouse gas emissions from motor vehicles under Section 202 of the Clean Air Act. This final action renders carbon dioxide and other greenhouse gases “regulated air pollutants” under the Clean Air Act.

In May 2010, the EPA released its Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule. The final rule, which numerous parties have challenged in the U.S. Court of Appeals for the D.C. Circuit, sets limits for greenhouse gas emissions that define when permits are required for new and existing industrial facilities under New Source Review PSD and Title V Operating Permit programs.

Federal laws, EPA regulations regarding greenhouse gases, or similar treaties, state laws, or rules, if enacted, could require Consumers to replace equipment, install additional equipment for emission controls, purchase emission allowances, curtail operations, arrange for alternative sources of supply, or take other steps to manage or lower the emission of greenhouse gases. Although associated capital or

operating costs relating to greenhouse gas regulation or legislation could be material and cost recovery cannot be assured, Consumers expects to recover these costs and capital expenditures in rates consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.

Coal Combustion By-Products: In June 2010, the EPA proposed rules regulating CCBs, such as coal ash, under the Resource Conservation and Recovery Act. Michigan already regulates CCBs as low-hazard industrial waste. The EPA proposed a range of alternatives for regulating CCBs, including regulation as either a non-hazardous waste or a hazardous waste. If coal ash were regulated as a hazardous waste, Consumers would likely cease the beneficial re-use of this product, resulting in significantly more coal ash requiring costly disposal. Additionally, it is possible that existing coal ash disposal areas could be closed and costly alternative arrangements for coal ash disposal could be required if the upgrades to hazardous waste landfill standards are economically prohibitive. Consumers is unable to predict accurately the full impacts from this wide range of possible outcomes, but significant expenditures are likely.

Water: In 2004, the EPA issued rules that govern existing electric generating plant cooling water intake systems. These rules require a significant reduction in the number of fish harmed by cooling water intake structures at existing power plants. The EPA compliance options in the rule were challenged before the U.S. Court of Appeals for the Second Circuit, which remanded the bulk of the rule back to the EPA for reconsideration in 2007. In April 2009, the U.S. Supreme Court ruled in favor of the utility industry’s position that the EPA can rely on a cost-benefit analysis in setting the national performance standards for fish protection. The EPA issued a request in July 2010 seeking information on how much utility customers are willing to pay to prevent fish from being killed or injured. This information request, as well as a renewed information request announced in August 2010, may indicate the EPA’s willingness to issue a revised draft rule in the near future.

Advance Notice of Proposed Rulemaking on PCBs: In April 2010, the EPA issued an Advance Notice of Proposed Rulemaking, indicating that it is considering a variety of regulatory actions with respect to PCBs. One proposal aims to phase out equipment containing PCBs by 2025. Another proposal eliminates an exemption for small equipment containing PCBs. Consumers could incur substantial costs associated with the regulation of PCBs due to prior installation of electrical equipment potentially containing PCBs.

Other electric environmental matters could have a major impact on Consumers’ outlook. For additional details on these and other electric environmental matters, see Note 3, Contingencies and Commitments, “Consumers’ Electric Utility Contingencies – Electric Environmental Matters.”

Electric Transmission: In June 2010, FERC issued a Notice of Proposed Rulemaking to establish a closer link between regional electric transmission planning and cost allocations to ensure the construction of required transmission facilities. In a related matter, MISO filed a tariff revision with FERC in July 2010, proposing a cost allocation methodology for new transmission projects. Consumers expects to continue to recover transmission expenses, including those associated with this proposal, through the PSCR process.

Electric Rate Matters: Rate matters are critical to Consumers’ electric utility business. For details on Consumers’ PSCR, electric rate cases, electric operation and maintenance expenditures show-cause order, Big Rock decommissioning proceedings, electric depreciation cases, renewable energy plan, and energy optimization plan, see Note 4, Utility Rate Matters, “Consumers’ Electric Utility Rate Matters.”

Consumers’ Gas Utility Business Outlook and Uncertainties

Gas Deliveries: Consumers expects 2010 weather-adjusted gas deliveries to be at a similar level to 2009. In addition, Consumers expects weather-adjusted gas deliveries to decline an average of one percent annually from 2011 through 2015, which includes expected effects of energy efficiency programs and continued conservation. Actual delivery levels from year to year may vary from this trend due to:

	•		fluctuations in weather;

	•		use by IPPs;

	•		availability and development of renewable energy sources;

	•		changes in gas prices;

	•		Michigan economic conditions, including population trends and housing activity;

	•		the price of competing energy sources or fuels; and

	•		energy efficiency and conservation.

In its 2009 gas rate case order, the MPSC authorized Consumers to adopt a decoupling mechanism. This mechanism, subject to certain conditions, allows Consumers to adjust future rates to collect or refund the change in marginal revenue by class arising from the difference between base sales per customer established in the order and weather-adjusted sales per customer. Consumers expects this mechanism to mitigate the impacts of energy efficiency programs, conservation, and changes in economic conditions on its gas revenue.

Gas Pipeline Safety: In September 2010, the U.S. House of Representatives passed the Corporate Liability and Emergency Accident Notification Act, which would require oil and natural gas pipeline operators to notify regulators within one hour following the discovery of certain oil spills or natural gas leaks. The bill also would increase civil fines for delayed reporting of oil spills and natural gas leaks and would establish an online searchable database of safety violations by pipeline owner or operator.

In response to the natural gas pipeline explosion that occurred in San Bruno, California in September 2010, the U.S. House of Representatives and the U.S. Senate have proposed bills stipulating stricter regulation of natural gas pipelines nationwide. These proposed bills affect primarily transmission pipelines and contain provisions mandating:

	•		the use of internal inspection devices or comparable methods effective in detecting pipeline deterioration;

	•		the installation of automatic shutoff equipment in high-consequence areas; and,

	•		certain disclosures to homeowners and regulatory agencies.

Consumers continues to comply with laws and regulations governing natural gas pipeline safety. If these proposed laws are put into effect, Consumers could incur significant additional costs related to its natural gas pipeline safety programs. Consumers expects that it would be able to recover some or all of the costs in rates, consistent with the recovery of other reasonable costs of complying with laws and regulations.

Gas Environmental Estimates: Consumers expects to incur investigation and remedial action costs at a number of sites, including 23 former MGP sites. For additional details, see Note 3, Contingencies and Commitments, “Consumers’ Gas Utility Contingencies – Gas Environmental Matters.”

Gas Rate Matters: Rate matters are critical to Consumers’ gas utility business. For details on Consumers’ GCR, gas rate cases, and gas depreciation case, see Note 4, Utility Rate Matters, “Consumers’ Gas Utility Rate Matters.”

Enterprises Outlook and Uncertainties

The primary focus with respect to CMS Energy’s remaining non-utility businesses is to optimize cash flow and maximize the value of their assets.

Trends, uncertainties, and other matters that could have a material impact on CMS Energy’s consolidated income, cash flows, or financial position include:

	•		indemnity and environmental remediation obligations at Bay Harbor;

	•		the outcome of certain legal proceedings;

	•		impacts of declines in electricity prices on the profitability of the enterprises segment’s generating units;

	•		representations, warranties, and indemnities provided by CMS Energy or its subsidiaries in connection with previous sales of assets;

	•		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;

	•		changes in various environmental laws, regulations, principles, practices, or in their interpretation; and

	•		economic conditions in Michigan, including population trends and housing activity.

For additional details regarding the enterprises segment’s uncertainties, see Note 3, Contingencies and Commitments.

Other Outlook and Uncertainties

Smart Grid: Consumers’ grid modernization effort continues to move forward. The foundation is installation of advanced metering and the infrastructure to support it. The installation will include smart meters that are capable of transmitting and receiving data, a two-way communications network, and modifications to Consumers’ existing systems to manage the data and enable changes to key business processes. It is intended to allow customers to monitor and manage their energy usage and help reduce demand during critical peak times, resulting in lower peak capacity requirements. Due to this system’s complexity and relative market immaturity, Consumers is using a phased implementation approach and intends to begin deployment of meters in early 2012.

Health Care Reform: For taxable years beginning after December 31, 2012, the Health Care Acts repeal the tax deduction for the portion of health care costs that are reimbursed by the Medicare Part D subsidy. This legislation resulted in a $3 million increase to CMS Energy’s tax expense for the nine months ended September 30, 2010, and it had no effect on Consumers’ net income. For additional details, see Note 10, Income Taxes.

Union Contracts: In April 2010, the Union ratified a new five-year agreement with Consumers for operating, maintenance, and construction employees. Consumers’ previous Union agreement expired in June 2010. In July 2010, the Union also ratified a new agreement with Consumers for virtual call center employees, which became effective in August 2010 upon the expiration of the previous Union agreement covering these employees. In October 2010, the United Steelworkers ratified a new agreement with Consumers for Zeeland employees, which will become effective in January 2011 upon the expiration of the previous agreement.

Litigation: CMS Energy, Consumers, and certain of their subsidiaries are named as parties in various litigation matters, as well as in administrative proceedings before various courts and governmental agencies arising in the ordinary course of business. For additional details regarding these and other legal matters, see Note 3, Contingencies and Commitments and Note 4, Utility Rate Matters.

EnerBank: EnerBank, a wholly owned subsidiary of CMS Capital that represents one percent of CMS Energy’s net assets, is a Utah state-chartered, FDIC-insured industrial bank providing unsecured home improvement loans. The carrying value of EnerBank’s loan portfolio was $331 million at September 30, 2010. Its loan portfolio was funded primarily by deposit liabilities of $319 million. Twelve-month rolling average default rates on loans held by EnerBank have declined from 2.1 percent at December 31, 2009 to 1.6 percent at September 30, 2010. EnerBank expects the level of loan defaults to continue to decline in 2010 and return gradually to historical levels of about 1.0 percent.

notes to consolidated financial statements

These interim Consolidated Financial Statements have been prepared by CMS Energy and Consumers in accordance with accounting principles generally accepted in the U.S. for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. As a result, CMS Energy and Consumers have condensed or omitted certain information and Note disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the U.S. CMS Energy and Consumers have reclassified certain prior period amounts to conform to the presentation in the current period. In management’s opinion, the unaudited information contained in this report reflects all adjustments of a normal recurring nature necessary to ensure 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 the 2009 Form 10-K. Due to the seasonal nature of CMS Energy’s and Consumers’ operations, the results presented for this interim period are not necessarily indicative of results to be achieved for the fiscal year.

1: NEW ACCOUNTING STANDARDS

IMPLEMENTATION OF NEW ACCOUNTING STANDARDS

SFAS No. 166, Accounting for Transfers of Financial Assets, an amendment of FASB Statement No. 140, codified through ASU No. 2009-16, Transfers and Servicing (Topic 860): Accounting for Transfers of Financial Assets: This standard, which was effective for CMS Energy and Consumers January 1, 2010, removes the concept of a QSPE from guidance relating to transfers of financial assets and extinguishments of liabilities. It also removes the exceptions from applying guidance relating to VIEs to QSPEs. This standard revises and clarifies when an entity is required to derecognize a financial asset that it has transferred to another entity. It further clarifies how to measure beneficial interests received as proceeds in connection with a transfer of a financial asset, and introduces the concept of a “participating interest,” the conditions of which must be met for a partial asset transfer to qualify for sale accounting treatment. The standard also requires enhanced disclosures related to continuing involvement with financial assets. Under this standard, transactions entered into under Consumers’ revolving accounts receivable sales program, discussed in Note 5, Financings, are accounted for as secured borrowings rather than as sales. CMS Energy and Consumers present outstanding amounts under the program as short-term debt collateralized by accounts receivable.

SFAS No. 167, Amendments to FASB Interpretation No. 46(R), codified through ASU No. 2009-17, Consolidations (Topic 810): Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities: This standard, which was effective for CMS Energy and Consumers January 1, 2010, amends the criteria used to determine which entity, if any, has a controlling financial interest in a VIE. It replaces the quantitative calculation of risks and rewards with a qualitative approach focused on identifying which entity (1) has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and (2) has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE. This standard also requires ongoing assessments of whether an entity is the primary beneficiary of a VIE. Upon implementation of this guidance, CMS Energy concluded that it is the primary beneficiary of CMS Energy Trust I and consolidated the trust in its consolidated financial statements on January 1, 2010. CMS Energy also concluded that it is not the primary beneficiary of T.E.S. Filer City, Grayling, or Genesee and deconsolidated these partnerships in its consolidated financial statements on January 1, 2010. CMS Energy consolidated CMS Energy Trust I at the carrying value that would be recorded had this guidance been effective when CMS Energy initially became involved with

CMS Energy Trust I. CMS Energy recorded its retained interest in the deconsolidated partnerships at the carrying value that would be recorded had this guidance been effective when CMS Energy initially became involved with the partnerships. CMS Energy and Consumers have chosen not to adjust previously reported balances. No cumulative effect adjustments were required. For additional details, see Note 11, Variable Interest Entities.

2: FAIR VALUE MEASUREMENTS

Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. When measuring fair value, CMS Energy and Consumers are required to incorporate all assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. A fair value hierarchy prioritizes inputs used to measure fair value according to their observability in the market. The three levels of the fair value hierarchy are as follows:

	•		Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

	•		Level 2 inputs are observable, market-based inputs, other than Level 1 prices. Level 2 inputs may include quoted prices for similar assets or liabilities in active markets, quoted prices in inactive markets, interest rates and yield curves observable at commonly quoted intervals, credit risks, default rates, and inputs derived from or corroborated by observable market data.

	•		Level 3 inputs are unobservable inputs that reflect CMS Energy’s or Consumers’ own assumptions about how market participants would value their assets and liabilities.

To the extent possible, CMS Energy and Consumers use quoted market prices or other observable market pricing data in valuing assets and liabilities measured at fair value. If this information is unavailable, they use market-corroborated data or reasonable estimates about market participant assumptions. CMS Energy and Consumers classify fair value measurements within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement in its entirety.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table summarizes, by level within the fair value hierarchy, CMS Energy’s and Consumers’ assets and liabilities reported at fair value on a recurring basis at September 30, 2010:

(c)		At December 31, 2009, CMS Energy’s liabilities classified as Level 3 represented 53 percent of CMS Energy’s total liabilities measured at fair value. The Level 3 liabilities consist primarily of an electricity sales agreement held by CMS ERM.

Cash Equivalents: Cash equivalents and restricted cash equivalents consist of money market funds with daily liquidity. The funds invest in U.S. Treasury notes, other government-backed securities, and repurchase agreements collateralized by U.S. Treasury notes.

Nonqualified Deferred Compensation Plan Assets: CMS Energy’s and Consumers’ nonqualified deferred compensation plan assets are invested in various mutual funds. CMS Energy and Consumers value these assets using a market approach, using the daily quoted NAVs provided by the fund managers that are the basis for transactions to buy or sell shares in each fund. CMS Energy and Consumers report these assets in Other non-current assets on their Consolidated Balance Sheets.

SERP Assets: CMS Energy and Consumers value their SERP assets using a market approach, incorporating prices and other relevant information from market transactions. The SERP cash equivalents consist of a money market fund with daily liquidity, which invests in state and municipal securities.

The SERP invests in a short-term, fixed-income mutual fund that holds a variety of debt securities with average maturities of one to three years. The fund invests primarily in investment-grade debt securities but, in order to achieve its investment objective, it may invest a portion of its assets in high-yield securities, foreign debt, and derivative instruments. The fair value of the fund is determined using the daily published NAV, which is the basis for transactions to buy or sell shares in the fund.

The SERP state and municipal bonds are investment grade securities that are valued using a matrix pricing model that incorporates Level 2 market-based information. The fair value of the bonds is derived from various observable inputs, including benchmark yields, reported trades, broker/dealer quotes, bond ratings, and general information on market movements normally considered by market participants when pricing such debt securities. CMS Energy and Consumers report their SERP assets in Other non-current assets on their Consolidated Balance Sheets. For additional details about SERP securities, see Note 7, Financial Instruments.

Nonqualified Deferred Compensation Plan Liabilities: CMS Energy and Consumers value their non-qualified deferred compensation plan liabilities based on the fair values of the plan assets, as they reflect what is owed to the plan participants in accordance with their investment elections. CMS Energy and Consumers report these liabilities in Other non-current liabilities on their Consolidated Balance Sheets.

Derivative Instruments: CMS Energy and Consumers value their derivative instruments using either a market approach that incorporates information from market transactions, or an income approach that discounts future expected cash flows to a present value amount. They use various inputs to value the derivatives depending on the type of contract and the availability of market data. CMS Energy has exchange-traded derivative contracts that are valued based on Level 1 quoted prices in actively traded markets, as well as derivatives that are valued using Level 2 inputs, including commodity market prices, interest rates, credit ratings, default rates, and market-based seasonality factors.

CMS Energy’s derivatives include an electricity sales agreement held by CMS ERM that extends beyond the term for which quoted electricity prices are available. To value this agreement, CMS Energy uses an internally developed model to project future prices. This method incorporates a proprietary forward power pricing curve that is based on forward gas prices and an implied heat rate. CMS Energy also increases the fair value of the liability for this agreement by an amount that reflects the uncertainty of its model. Since the modeling technique is significant to the overall fair value measurement, this agreement is classified as Level 3.

For all fair values other than Level 1 prices, CMS Energy and Consumers incorporate adjustments for the risk of nonperformance. For derivative assets, a credit adjustment is applied against the asset based on the published default rate for the credit rating that CMS Energy and Consumers assign to the counterparty based on an internal credit-scoring model. This model considers various inputs, including the counterparty’s financial statements, credit reports, trade press, and other information that would be available to market participants. To the extent that the internal ratings are comparable to credit ratings published by independent rating agencies, the resulting credit adjustment is classified within Level 2. If the internal model results in a rating that is outside of the range of ratings given by the independent agencies and the credit adjustment is significant to the overall valuation, the derivative fair value is classified as Level 3. CMS Energy and Consumers adjust their derivative liabilities downward to reflect the risk of their own nonperformance, based on their published credit ratings. Adjustments for credit risk using the approach outlined within this paragraph are not materially different from the adjustments that would result from using credit default swap rates for the contracts presently held. For additional details about derivative contracts, see Note 8, Derivative Instruments.

Assets and Liabilities Measured at Fair Value on a Recurring Basis using Significant Level 3 Inputs

The following table is a reconciliation of changes in the fair values of Level 3 assets and liabilities at CMS Energy, which includes Level 3 assets and liabilities at Consumers:

(a)		CMS Energy records realized and unrealized gains and losses for Level 3 recurring fair values in earnings as a component of Operating Revenue or Maintenance and other operating expenses on its Consolidated Statements of Income.

At September 30, 2010, Consumers held $1 million in assets classified as Level 3. No further detail is provided on Consumers’ Level 3 assets, due to the immateriality of the amounts.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

The following table summarizes, by level within the fair value hierarchy, CMS Energy’s assets reported at fair value on a nonrecurring basis during the nine months ended September 30, 2010:


In Millions
							Gains
	Level 1		Level 2		Level 3		(Losses)

CMS Energy, including Consumers
Assets held for sale	$	—	$	—	$	7	$	(4	)

In June 2010, CMS Energy wrote down assets held for sale from their carrying amount of $11 million to their fair value of $7 million, resulting in a loss of $4 million, which was recorded in earnings as part of discontinued operations for the nine months ended September 30, 2010. The fair value was determined based on a discounted cash flow technique. The reduction in fair value was due primarily to declines in forward electricity prices. Consumers did not have any nonrecurring fair value measurements during the nine months ended September 30, 2010.

3: CONTINGENCIES AND COMMITMENTS

CMS ENERGY CONTINGENCIES

Gas Index Price Reporting Investigation: In 2002, CMS Energy 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 cooperated 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 2003, and CMS Energy completed its response to this request in 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.

Gas Index Price Reporting Litigation: CMS Energy, along with CMS MST, CMS Field Services, Cantera Natural Gas, Inc., and Cantera Gas Company, are named as defendants in various class action and individual lawsuits arising as a result of alleged inaccurate natural gas price reporting to publications that report trade information. Allegations include manipulation of NYMEX natural gas futures and options prices, price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices in Colorado, Kansas, Missouri, Tennessee, and Wisconsin. The following provides more detail on these proceedings:

	•		In 2005, CMS MST was served with a summons and complaint that 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. The complaint alleges that during the putative class period, January 1, 2000 through October 31, 2002, the defendants engaged in a scheme to violate the Kansas Restraint of Trade Act. The plaintiffs, who allege they purchased natural gas from the defendants and others for their facilities, are seeking statutory full consideration damages consisting of the full consideration paid by plaintiffs for natural gas.

	•		In 2007, a class action complaint, Heartland Regional Medical Center, et al. v. Oneok, Inc. et al., was filed in Missouri state court alleging violations of Missouri antitrust laws. Defendants, including CMS Energy, CMS Field Services, and CMS MST, are alleged to have violated the Missouri antitrust law in connection with their natural gas price reporting activities.

	•		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.

	•		A class action complaint, Arandell Corp., et al. v. XCEL Energy Inc., et al., was filed in 2006 in Wisconsin state court on behalf of Wisconsin commercial entities that purchased natural gas between January 1, 2000 and October 31, 2002. The defendants, including CMS Energy, CMS ERM, and Cantera Gas Company, are alleged to have violated Wisconsin’s antitrust statute. The plaintiffs are seeking full consideration damages, plus exemplary damages, and attorneys’ fees. After dismissal on jurisdictional grounds in 2009, plaintiffs filed a new Arandell case in Michigan. The CMS Energy defendants filed a motion to dismiss the new Michigan case on statute-of-limitations grounds and that motion remains pending.

	•		Another class action complaint, Newpage Wisconsin System v. CMS ERM, CMS Energy, and Cantera Gas Company, was filed in 2009 in circuit court in Wood County, Wisconsin, against CMS Energy defendants and 19 other non-CMS Energy companies. The plaintiff is seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees.

	•		In 2005, J.P. Morgan Trust Company, in its capacity as Trustee of the FLI Liquidating Trust, filed an action in Kansas state court 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. The plaintiff is seeking statutory full consideration damages for its purchases of natural gas between January 1, 2000 and December 31, 2001. This case is part of the MDL proceeding, but is not a class action.

After removal to federal court, the Learjet, Heartland, Breckenridge, both Arandell cases, Newpage, and J.P. Morgan cases were transferred to the MDL case. CMS Energy was dismissed from the Learjet, Heartland, and J.P. Morgan cases in 2009, but other CMS Energy defendants remain parties. All CMS Energy defendants were dismissed from the Breckenridge case in 2009. It is expected that the plaintiffs in this case will appeal this decision after all claims against defendants have been dismissed. At this time, there is no pending appeal. In June 2010, CMS Energy and Cantera Gas Company were dismissed from the Newpage case; the Arandell (Wisconsin) case was reinstated against CMS ERM; and the Arandell (Wisconsin) case was consolidated with the Newpage case. These two consolidated cases remain pending only against CMS ERM. Pending before the court in all of the MDL cases are the defendants’ renewed motions for summary judgment based on FERC preemption and the plaintiffs’ motion for leave to amend their complaint to add a federal Sherman Act antitrust claim. In all but the

J.P. Morgan case, there are also pending plaintiffs’ motions for class certification. These motions are not yet decided.

	•		In 2005, 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. The defendants included CMS Energy, CMS MST, and CMS Field Services. In April 2010, the Tennessee Supreme Court dismissed all claims against all defendants.

	•		In 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., alleging violation of the Missouri antitrust law, fraud, and unjust enrichment. In 2009, all defendants were dismissed for lack of standing. The Missouri Court of Appeals affirmed the dismissals in late 2009. In February 2010, the plaintiff filed an application for leave to appeal with the Missouri Supreme Court, seeking to overturn the Missouri Court of Appeals decision and in September 2010, the Missouri Supreme Court affirmed the dismissal of this case.

These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions. Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s possible loss would be based on widely varying models previously untested in this context. Defenses are being pursued vigorously, which could result in the dismissal of the cases completely, but CMS Energy is unable to predict the outcome of these matters. If the outcome is unfavorable, these cases could have a material adverse impact on CMS Energy’s financial condition and results of operations.

Bay Harbor: As part of the development of Bay Harbor by certain subsidiaries of CMS Energy, and under an agreement with the MDNRE, third parties constructed a golf course and park over several abandoned CKD piles left over from the former cement plant operations on the Bay Harbor site. The third parties also undertook a series of response activities, including constructing a leachate collection system in one area where CKD-impacted groundwater was entering Little Traverse Bay. Leachate is produced when water enters into the CKD piles. In 2002, CMS Energy sold its interest in Bay Harbor, but retained its obligations under environmental indemnities entered into at the start of the project.

In 2005, the EPA, along with CMS Land and CMS Capital, voluntarily executed an AOC under Superfund, and the EPA approved a Removal Action Work Plan to address contamination issues. Collection systems required under the plan have been installed and effectiveness monitoring of the systems at the shoreline is ongoing. CMS Land, CMS Capital, and the EPA agreed upon augmentation measures to address areas where pH measurements were not satisfactory. Several augmentation measures were implemented and completed in 2009, with the remaining measure scheduled for completion in late 2010.

In 2008, the MDNRE and the EPA granted permits for CMS Land or its affiliate, Beeland, to construct and operate a deep injection well in Antrim County, Michigan, to dispose of leachate from Bay Harbor. Certain environmental groups, a local township, and a local county filed lawsuits appealing the permits. The legal proceeding was stayed in 2009 and can be renewed by either party at any time. CMS Land and CMS Capital continue to seek a lower cost long-term water disposal option that will likely include a permitted discharge to surface water or a deep injection well.

Various claims have been brought against CMS Land or its affiliates, including CMS Energy, alleging environmental damage to property, loss of property value, insufficient disclosure of environmental matters, breach of agreement relating to access, or other matters. There is presently one lawsuit (Jankowski v. CMS Energy, CMS Capital, and CMS Land) pending that was filed in June 2010 in Emmet County Circuit Court in Michigan relating to such subjects. CMS Land and other parties recently received a demand for payment from the EPA in the amount of $7 million, plus interest, whereby the EPA is seeking recovery, as allowed under Superfund, of EPA’s response costs incurred at the Bay Harbor site. CMS Land believes that this is not a valid claim and intends to dispute it.

CMS Land and CMS Capital, the MDNRE, the EPA, and other parties are negotiating the long-term remedy for the Bay Harbor sites, including:

	•		the disposal of leachate;

	•		the capping and excavation of CKD;

	•		the location and design of collection lines and upstream water diversion systems;

	•		potential flow of leachate below the collection system;

	•		application of criteria for various substances such as mercury; and

	•		other matters that are likely to affect the scope of response activities that CMS Land and CMS Capital may be obligated to undertake.

CMS Energy has recorded a cumulative charge related to Bay Harbor of $181 million. At September 30, 2010, CMS Energy had a recorded liability of $66 million for its remaining obligations. CMS Energy calculated this liability based on discounted projected costs, using a discount rate of 4.32 percent and an inflation rate of one percent on annual operating and maintenance costs. CMS Energy based the discount rate on the interest rate for 30-year U.S. Treasury securities on June 30, 2009. The undiscounted amount of the remaining obligation is $86 million. CMS Energy expects to pay $7 million during the remainder of 2010, $9 million in 2011, $7 million in 2012, $5 million in 2013, and the remaining amount thereafter on long-term liquid disposal and operating and maintenance costs.

CMS Energy’s estimate of response activity costs and the timing of expenditures could change if there are additional major changes in circumstances or assumptions, including but not limited to:

	•		inability to secure a suitable long-term water disposal option at a reasonable cost;

	•		further increases in water disposal costs under existing options;

	•		delays in developing a long-term water disposal option;

	•		an increase in the number of contamination areas;

	•		different remediation techniques;

	•		the nature and extent of contamination;

	•		inability to reach agreement with the MDNRE or the EPA over additional response activities;

	•		delays in the receipt of requested permits;

	•		delays following the receipt of any requested permits due to legal appeals of third parties;

	•		additional or new legal or regulatory requirements; or

	•		new or different landowner claims.

Depending on the size of any indemnity obligation or liability under environmental laws, an adverse outcome of this matter could have a material adverse effect on CMS Energy’s liquidity and financial condition and could negatively affect CMS Energy’s financial results. CMS Energy cannot predict the financial impact or outcome of this matter.

State Street Bank and TSU Litigation: In 2002, State Street Bank sued CMS Viron in the District Court of Harris County, Texas, claiming primarily a breach of representations and warranties and seeking $9 million plus interest from CMS Viron. During the same year, CMS Viron filed a counterclaim, as well as third-party actions against TSU, Academic Capital Group, Inc., and Academic Services, Inc. for breach of contract and fiduciary duties and conversion. In December 2009, the jury rendered a verdict in favor of CMS Viron and a final judgment was rendered on January 15, 2010 awarding CMS Viron $8 million plus prejudgment interest from TSU and another $3 million plus prejudgment interest and attorneys’ fees against Academic Capital Group, Inc. and Academic Services, Inc., collectively. This verdict is affected by an agreement under which CMS Viron is required to pay $3 million to State Street Bank regardless of the verdict. In addition, State Street Bank agreed to assign certain rights of indemnification under a lease agreement to CMS Viron in return for a two-thirds stake in any ultimate recovery from TSU. At September 30, 2010, CMS Energy had a recorded liability of $3 million for its potential obligation related to this matter. CMS Viron has agreed to accept less than $1 million to settle the Academic Capital judgment. TSU opposes payment of its judgment on the grounds of sovereign immunity.

Equatorial Guinea Tax Claim: In 2004, CMS Energy received a request for indemnification from the purchaser of CMS Oil and Gas. The indemnity claim relates to the sale of CMS Energy’s oil, gas, and methanol projects in Equatorial Guinea and the claim of the government of Equatorial Guinea that CMS Energy owes $142 million in taxes in connection with that sale. CMS Energy concluded that the government’s tax claim is without merit and the purchaser of CMS Oil and Gas submitted a response to the government rejecting the claim. The government of Equatorial Guinea has indicated that it still intends to pursue its claim. CMS Energy cannot predict the financial impact or outcome of this matter.

Marathon Indemnity Claim regarding F.T. Barr Claim: In 2001, F.T. Barr filed a lawsuit in Harris County District Court in Texas against CMS Energy, CMS Oil and Gas, and other defendants alleging that his overriding royalty payments related to Alba field production were improperly calculated. In 2004, all parties signed a confidential settlement agreement that resolved claims between Barr and the defendants. The CMS Energy defendants reserved all defenses to any indemnity claim relating to the settlement.

In April 2009, certain Marathon entities filed a case in the U.S. District Court for the Southern District of Texas against CMS Enterprises for indemnification in connection with this matter. CMS Energy entities dispute Marathon’s claim, and are opposing it vigorously. CMS Energy entities also assert that Marathon has suffered minimal, if any, damages. CMS Energy cannot predict the outcome of this matter. If Marathon’s claim were sustained, it would have a material effect on CMS Energy’s future earnings and cash flow.

Former NOMECO Employees’ Litigation: In June 2010, eight former employees of NOMECO filed a lawsuit in Ingham County Circuit Court in Michigan against CMS Energy and three Marathon entities (Richard Rulewicz, Trustee of the Richard Rulewicz Revocable Living Trust, et al. v. CMS Energy) alleging underpayment of the former employees’ overriding royalty payments related to the Alba field production in Equatorial Guinea, to which the plaintiffs claim to be entitled. CMS Oil and Gas sold its interests in the Alba field to Marathon in 2002. CMS Energy believes that it may be entitled to full or partial indemnification from Marathon for monetary damages that may arise from this lawsuit. CMS Energy cannot predict the financial impact or outcome of this matter.

CONSUMERS’ ELECTRIC UTILITY CONTINGENCIES

Electric Environmental Matters: Consumers’ operations are subject to environmental laws and regulations. Generally, Consumers has been able to recover, in customer rates, the costs to operate its facilities in compliance with these laws and regulations.

Cleanup and Solid Waste: Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. At September 30, 2010, Consumers had a recorded liability of $2 million, its estimated probable NREPA liability.

Consumers is a potentially responsible party at a number of contaminated sites administered under the Superfund. Superfund liability is joint and several. In addition to Consumers, many other creditworthy parties with substantial assets are potentially responsible with respect to the individual sites. Based on its experience, Consumers estimates that its share of the total liability for known Superfund sites will be between $2 million and $8 million. Various factors, including the number of potentially responsible parties involved with each site, affect Consumers’ share of the total liability. At September 30, 2010, Consumers had a recorded liability of $2 million, the minimum amount in the range of its estimated probable Superfund liability.

The timing of payments related to Consumers’ remediation and other response activities at its Superfund and NREPA sites is uncertain. Consumers periodically reviews these cost estimates. Any significant change in the underlying 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 its estimates of NREPA and Superfund liability.

Ludington PCB: In 1998, during routine maintenance activities, Consumers identified PCB as a component in certain paint, grout, and sealant materials at Ludington. Consumers removed and replaced part of the PCB material with non-PCB material. Since proposing a plan to take action with respect to the remaining materials, Consumers has had several communications with the EPA. Consumers is not able to predict when the EPA will issue a final ruling and cannot predict the financial impact or outcome of this matter.

Electric Utility Plant Air Permit Issues and Notices of Violation: In 2007, Consumers received an NOV/FOV from the EPA alleging that fourteen utility boilers exceeded the visible emission limits in their associated air permits. Consumers has responded formally to the NOV/FOV denying the allegations. In addition, in 2008, Consumers received an NOV for three of its coal-fueled facilities alleging, among other things, violations of NSR PSD regulations relating to ten projects from 1986 to 1998 allegedly subject to NSR review. The EPA has alleged that some utilities have classified incorrectly major plant modifications as RMRR rather than seeking permits from the EPA or state regulatory agencies to modify their plants. Consumers responded to the information requests from the EPA on this subject in the past. Consumers believes that it has properly interpreted the requirements of RMRR.

Consumers is engaged in discussions with the EPA on all of these matters. Depending upon the outcome of these discussions, the EPA could bring legal action against Consumers and/or Consumers could be required to install additional pollution control equipment at some or all of its coal-fueled electric generating plants, surrender emission allowances, engage in Supplemental Environmental Programs, and/or pay fines. Additionally, Consumers would need to assess the viability of continuing operations at certain plants. Consumers cannot predict the financial impact or outcome of these matters. Although the potential costs relating to these matters could be material and cost recovery cannot be reasonably estimated, Consumers expects that it would be able to recover some or all of the costs in rates, consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.

Nuclear Matters:

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 Consumers and other utilities participated, has not been successful in producing more specific relief for the DOE’s failure to accept the spent nuclear fuel.

A number of court decisions support the right of utilities to pursue damage claims in the U.S. Court of Claims against the DOE for failure to take delivery of spent nuclear fuel. Consumers filed a complaint in 2002. If Consumers’ litigation against the DOE is successful, Consumers plans to use any recoveries as reimbursement for the incurred costs of spent nuclear fuel storage during Consumers’ ownership of Palisades and Big Rock. Consumers cannot predict the financial impact or outcome of this matter. 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 Consumers’ ownership of Palisades and Big Rock.

Nuclear Fuel Disposal Cost: Consumers has a recorded liability of $163 million for amounts it collected from customers before 1983 to fund the disposal of spent nuclear fuel. This amount, which includes interest of $119 million, is payable to the DOE when it begins to accept delivery of spent nuclear fuel. In conjunction with the sale of Palisades and the Big Rock ISFSI in 2007, Consumers retained this obligation and provided a letter of credit to Entergy as security for this obligation.

CONSUMERS’ GAS UTILITY CONTINGENCIES

Gas Environmental Matters: Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA. These sites include 23 former MGP facilities. Consumers operated the facilities on these sites for some part of their operating lives. For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site. At September 30, 2010, Consumers estimated its undiscounted remaining remediation and other response activity costs to be between $32 million and $47 million. Generally, Consumers has been able to recover most of its costs to date through proceeds from insurance settlements and customer rates.

At September 30, 2010, Consumers had a recorded liability of $32 million and a regulatory asset of $59 million that included $27 million of deferred MGP expenditures. The timing of payments related to the remediation and other response activity at Consumers’ former MGP sites is uncertain. Consumers expects its remediation and other response activity costs to average $6 million annually over the next five years. Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, changes in remediation techniques, or legal and regulatory requirements, could affect Consumers’ estimates of annual response activity costs and the MGP liability.

CONSUMERS’ OTHER CONTINGENCIES

Employee Discrimination Litigation: In October 2010, the jury in a federal court action in Grand Rapids, Michigan, returned a verdict against Consumers and in favor of the plaintiff, a Consumers employee, of $0.4 million in compensatory damages and $7.5 million in punitive damages on a claim of hostile work environment. Consumers has filed a motion to reduce the verdict to a statutory cap under federal law, which is believed to be $0.3 million. Consumers intends to pursue vigorously additional motions for relief before the trial court and, if necessary, the federal court of appeals. Consumers believes that if the award were upheld, Consumers’ insurance would pay for most of the damages.

(a)		The majority of this amount arises from stock and asset sales agreements under which CMS Energy or a subsidiary of CMS Energy, other than Consumers, indemnified the purchaser for losses resulting from various matters, including claims related to tax disputes, claims related to PPAs, and defects in title to the assets or stock sold to the purchaser by CMS Energy subsidiaries. Except for items described elsewhere in this Note, CMS Energy believes the likelihood of material loss to be remote for the indemnity obligations not recorded as liabilities.

(b)		At September 30, 2010, the carrying amount of CMS Land’s put option agreements with certain Bay Harbor property owners was $1 million. If CMS Land is required to purchase a Bay Harbor property under a put option agreement, it may sell the property to recover the amount paid under the put option agreement.

At September 30, 2010, the maximum obligation and carrying amounts for Consumers’ guarantees were less than $1 million.

The following table provides additional information regarding CMS Energy’s guarantees:



		Events That Would Require
Guarantee Description	How Guarantee Arose	Performance

Indemnity obligations from asset sales and other agreements	Stock and asset sales agreements	Findings of misrepresentation, breach of warranties, tax claims, and other specific events or circumstances

Surety bonds and other indemnity obligations	Normal operating activity, permits and licenses	Nonperformance

Guarantees and put options	Normal operating activity	Nonperformance or non-payment by a subsidiary under a related contract

	Bay Harbor remediation efforts	Owners exercising put options requiring CMS Land to purchase property

CMS Energy, Consumers, and certain other subsidiaries of CMS Energy also enter into various agreements containing tax and other indemnity provisions for which they are unable to estimate the maximum potential obligation. These factors include unspecified exposure under certain agreements. CMS Energy and Consumers consider the likelihood that they would be required to perform or incur substantial losses related to these indemnities to be remote.

OTHER CONTINGENCIES

In addition to the matters disclosed in this Note and Note 4, Utility Rate Matters, there are certain other lawsuits and administrative proceedings before various courts and governmental agencies arising in the ordinary course of business to which CMS Energy, Consumers, and certain other subsidiaries of CMS Energy are parties. These other lawsuits and proceedings may involve personal injury, property damage, contracts, environmental issues, federal and state taxes, rates, licensing, and other matters. Further, CMS Energy and Consumers occasionally self-report certain regulatory non-compliance matters that may or may not eventually result in administrative proceedings. CMS Energy and Consumers believe that the outcome of any one of these proceedings will not have a material adverse effect on their consolidated results of operations, financial position, or cash flows.

4: UTILITY RATE MATTERS

Rate matters are critical to Consumers. Depending upon the specific issues, the outcomes of rate cases and proceedings could have a material adverse effect on Consumers’ cash flows and results of operations.

CONSUMERS’ ELECTRIC UTILITY RATE MATTERS

Power Supply Cost Recovery: The PSCR process is designed to allow Consumers to recover all of its power supply costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its PSCR billing factor monthly in order to minimize the overrecovery or underrecovery amount in the annual PSCR reconciliation.

PSCR Reconciliations: The following table summarizes the PSCR reconciliation filing pending with the MPSC:



			PSCR Cost of
PSCR Year	Date Filed	Net Underrecovery	Power Sold

2009	March 2010	$39 million (a)	$1.6 billion


(a)		In 2005, the MPSC approved an economic development discount for a large industrial customer to promote long-term investments in the industrial infrastructure of Michigan. It was determined in the November 2009 electric rate case order that recovery of this discount should be provided through the electric general rates that Consumers self-implemented in May 2009. That order, however, did not address the recovery of the power-supply component of the discount provided from January 2009 through self-implementation, which totaled $4 million. Consumers has requested recovery of this amount through its 2009 PSCR reconciliation.

In March 2010, the MPSC issued an order in Consumers’ 2007 PSCR reconciliation, disallowing PSCR recovery of $3 million of economic development discounts and $4 million of net replacement power costs associated with a crane incident at Consumers’ Campbell plant. The MPSC approved the 2007 PSCR reconciliation, as modified by the order, and authorized Consumers to include an underrecovery of $21 million in its 2008 PSCR plan. In April 2010, Consumers filed for a rehearing in its 2007 PSCR reconciliation, asking the MPSC to reconsider its decision to disallow recovery of a $2 million economic development discount provided in 2007 to a large industrial customer. In June 2010, the MPSC denied Consumers’ petition for rehearing. In July 2010, Consumers filed a claim for appeal with the Michigan Court of Appeals regarding the MPSC’s decision to disallow recovery of the economic development discount. Consumers cannot predict the outcome of this proceeding.

In June 2010, the MPSC issued an order in Consumers’ 2008 PSCR reconciliation, disallowing PSCR recovery of a $3 million economic development discount. The MPSC approved the 2008 PSCR reconciliation, as modified by the order, and authorized Consumers to include an overrecovery of $14 million in its 2009 PSCR reconciliation. In July 2010, Consumers filed for a rehearing in its 2008 PSCR reconciliation, asking the MPSC to reconsider its decision to disallow recovery of the $3 million economic development discount. Consumers cannot predict the outcome of this proceeding.

PSCR Plan: In September 2009, Consumers submitted its 2010 PSCR plan to the MPSC. In accordance with its proposed plan, Consumers self-implemented the 2010 PSCR charge beginning in January 2010. In July 2010, the ALJ recommended that the MPSC approve Consumers’ 2010 PSCR plan with the exception of $5 million of gas transportation costs related to Zeeland.

In September 2010, Consumers submitted its 2011 PSCR plan to the MPSC. In accordance with its proposed plan, Consumers expects to self-implement the 2011 PSCR charge beginning in January 2011.

While Consumers expects to recover all of its PSCR costs, it cannot predict the financial impact or outcome of these proceedings.

Electric Rate Cases: The MPSC, through a final order and rehearing in Consumers’ 2009 electric rate case, directed Consumers to refund to customers the difference between the rates it self-implemented in May 2009 and the rates authorized in the order, plus interest, subject to a reconciliation proceeding. In August 2010, the MPSC ordered Consumers to refund self-implemented revenue of $16 million to customers. Consumers refunded this amount in September 2010.

The MPSC’s order in Consumers’ 2009 electric rate case also adopted a pilot decoupling mechanism and an uncollectible expense tracking mechanism. At September 30, 2010, Consumers had a $31 million regulatory asset for electric decoupling recorded on its Consolidated Balance Sheets. Various parties have filed appeals concerning aspects of the MPSC order, including both the pilot decoupling mechanism and the uncollectible expense tracking mechanism. Consumers cannot predict the outcome of these proceedings.

In January 2010, Consumers filed an application with the MPSC seeking an annual increase in revenue of $178 million based on an 11 percent authorized return on equity. The filing requested authority to recover new investments in system reliability, environmental compliance, and technology advancements. In August 2010, the MPSC Staff recommended a revenue increase of $91 million, based on a 10.35 percent return on equity. The MPSC Staff also recommended an additional revenue increase of $35 million if the MPSC denies Consumers’ request for a mechanism to track an economic development discount provided to a large industrial customer.

In July 2010, Consumers self-implemented an annual electric rate increase of $150 million, subject to refund with interest. Consumers self-implemented $28 million less than it originally requested in order to respond to concerns raised by the MPSC Staff and other intervenors and to provide a balance between the need for investment in Michigan’s infrastructure, which will support economic recovery in the state, and the resulting rate impacts on customers. The following table details the components of Consumers’ self-implemented electric rate increase and the increase recommended by the MPSC Staff:


						In Millions
			Increase
	Consumers’		Recommended
	Self-Implemented		by the
Components of the increase in revenue	Increase		MPSC Staff			Difference

Investment in rate base	$	106	$	74		$	(32	)
Recovery of operating and maintenance costs		21		32			11
Return on equity		18		(19	)		(37	)
Impact of sales declines		5		4			(1	)

Total	$	150	$	91	(a)	$	(59	)


(a)		Does not include the $35 million of additional revenue the MPSC Staff recommends if the MPSC denies Consumers’ request for an economic development discount tracking mechanism.

In its July 2010 order allowing Consumers to self-implement the $150 million increase, the MPSC expressed concern about utilities repeatedly self-implementing rate increases over short time periods, and before the return of previous overcollections of self-implemented rate increases. The MPSC also resolved to dispense with the ALJ’s PFD in this rate case, in order to shorten the amount of time during which self-implemented rates will be in effect. In August 2010, the Attorney General filed a claim for appeal with the Michigan Court of Appeals regarding the MPSC’s July 2010 order. Consumers cannot predict the financial impact or outcome of this electric rate case.

Electric Operation and Maintenance Expenditures Show-Cause Order: In December 2005, the MPSC authorized Consumers to increase its electric rates. In the same order, the MPSC ordered Consumers to spend certain amounts on future tree-trimming and line-clearing activities, as well as on the operation and maintenance of Consumers’ fossil-fueled power plants. At that time, the MPSC also ordered Consumers to establish mechanisms to track these expenditures and stated that the rate increase was subject to refund with interest if the specified amounts were not spent on these activities.

In October 2009, the MPSC issued a show-cause order alleging that, in 2007, Consumers spent $14 million less on forestry and fossil-fueled plant operation and maintenance activity than the amount ordered by the MPSC and that Consumers has not refunded this amount to customers. The order directed Consumers to explain why it should not be found in violation of the MPSC’s December 2005 order and

subjected to applicable sanctions, and why the refunds required by that order have not yet occurred. Consumers’ response indicated that the total amount it spent on forestry and fossil-fueled plant operation and maintenance activity for the years 2006 through 2009 exceeded the total amounts included in rates for these activities.

In March 2010, the MPSC Staff requested that the MPSC find Consumers in violation of the December 2005 order and that the MPSC order Consumers to refund $27 million for failure to meet annual spending requirements during 2007 and 2008. Consumers filed a response, stating that it would be unreasonable and unlawful to order a refund of this amount and that Consumers’ expenditures were consistent with the MPSC’s orders. In March 2010, the ALJ’s PFD found Consumers’ expenditures to be prudent and that Consumers did not violate the December 2005 order. The ALJ recommended that the MPSC find that no violation of the December 2005 order occurred and that no refunds be made to customers. Consumers cannot predict the outcome of this proceeding.

Big Rock Decommissioning: The MPSC and FERC regulate the recovery of Consumers’ costs to decommission Big Rock. Subsequent to 2000, Consumers stopped funding a Big Rock trust fund because the collection period for an MPSC-authorized decommissioning surcharge expired on that date. The level of funds provided by the trust fell short of the amount needed to complete decommissioning and Consumers provided $44 million of corporate contributions for decommissioning costs.

In an order issued in February 2010, the MPSC concluded that certain revenues collected during a statutory rate freeze from 2001 through 2003 should have been deposited in the decommissioning trust fund. The MPSC agreed that Consumers was entitled to recover the $44 million decommissioning shortfall, but concluded that Consumers had collected this amount previously through the rates in effect during the rate freeze. In April 2010, the MPSC ordered Consumers to refund $85 million of revenue collected in excess of decommissioning costs plus interest, over seven months beginning in July 2010. At September 30, 2010, Consumers had a $44 million regulatory liability recorded on its Consolidated Balance Sheets for this refund. Consumers filed an appeal with the Michigan Court of Appeals in March 2010 to dispute the MPSC’s conclusion that the collections received during the rate freeze should be subject to refund. Consumers cannot predict the outcome of this proceeding.

Consumers has paid $30 million to Entergy to assume ownership and responsibility for the Big Rock ISFSI, and has incurred $55 million for nuclear fuel storage costs as a result of the DOE’s failure to accept spent nuclear fuel. Consumers is seeking recovery of these costs from the DOE. At September 30, 2010, Consumers had an $85 million regulatory asset recorded on its Consolidated Balance Sheets for these costs.

Electric Depreciation: In February 2010, Consumers filed an electric depreciation case related to its wholly owned electric utility property. As ordered by the MPSC, Consumers prepared a traditional cost-of-removal study, which supported a $46 million increase in annual depreciation expense.

Also in February 2010, Consumers filed an electric depreciation case for Ludington, the pumped storage plant jointly owned by Consumers and Detroit Edison. This case, filed jointly with Detroit Edison, requests an increase in annual depreciation expense. Consumers’ share of this increase is $9 million annually. Consumers cannot predict the financial impact or outcome of these proceedings.

Renewable Energy Plan: In June 2010, Consumers filed its first annual report and reconciliation for its renewable energy plan with the MPSC, requesting approval of Consumers’ reconciliation of renewable energy plan costs for 2009.

Energy Optimization Plan: In April 2010, Consumers filed its first annual report and reconciliation for its energy optimization plan with the MPSC, requesting approval of Consumers’ reconciliation of energy optimization plan costs for 2009. Consumers also requested approval of the collection of a $6 million

incentive payment for both its gas and electric energy optimization plans. During 2009, Consumers achieved 134 percent of its electric savings target and 132 percent of its gas savings target. These achievements qualify Consumers to earn the maximum incentive allowed by the MPSC, which is calculated as 15 percent of Consumers’ investment in energy savings.

As one of the conditions to the continuation of the electric and gas pilot decoupling mechanisms, Consumers must exceed the statutory savings targets specified in the 2008 Energy Legislation for 2011 through 2014. In September 2010, Consumers filed an amended energy optimization plan to recover the additional spending necessary to exceed these savings targets.

CONSUMERS’ GAS UTILITY RATE MATTERS

Gas Cost Recovery: The GCR process is designed to allow Consumers to recover all of its purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its GCR billing factor monthly in order to minimize the overrecovery or underrecovery amount in the annual GCR reconciliation.

GCR Reconciliations: The following table summarizes the GCR reconciliation filings pending with the MPSC:



			GCR Cost of
GCR Year	Date Filed	Net (Under)/Over recovery	Gas Sold

2008-2009	June 2009	$(15) million (a)	$1.8 billion
2009-2010	June 2010	$1 million	$1.3 billion


(a)		In August 2010, the ALJ recommended that the MPSC allow Consumers to include its $15 million net underrecovery in the 2009-2010 GCR plan year.

GCR Plans: In March 2010, the MPSC authorized Consumers to implement its 2009-2010 base GCR factor and generally approved Consumers’ plan.

In December 2009, Consumers filed an application with the MPSC seeking approval of a GCR plan for its 2010-2011 GCR plan year. In April 2010, Consumers self-implemented its filed GCR plan. In September 2010, the ALJ recommended that the MPSC approve Consumers’ 2010-2011 GCR plan with certain adjustments to its purchasing guidelines and contingent cost recovery methodology. While Consumers expects to recover all of its GCR costs, it cannot predict the financial impact or outcome of these proceedings.

Gas Rate Cases: In May 2009, Consumers filed an application with the MPSC seeking an annual increase in revenue of $114 million based on an 11 percent authorized return on equity. The filing requested authorization to implement an uncollectible expense tracking mechanism, Pension Plan and OPEB equalization mechanisms, as well as a revenue decoupling mechanism.

In November 2009, Consumers self-implemented a gas rate increase in the annual amount of $89 million. In May 2010, the MPSC issued its order in this case, authorizing Consumers to increase its rates by $66 million based on an authorized return on equity of 10.55 percent. The following table details the components of Consumers’ self-implemented gas rate increase and the increase authorized by the MPSC:


In Millions
	Consumers’		Increase

Components of the increase in revenue	Increase		the MPSC		Difference

Recovery of operating and maintenance costs		17		13		(4)
Return on equity		8		(2)		(10)

Total	$	89	$	66	$	(23)

The MPSC directed Consumers to refund to customers the difference between the rates it self-implemented in November 2009 and the rates authorized in this order, plus interest, subject to a reconciliation proceeding.

The order also approved a revenue decoupling mechanism, effective June 1, 2010, which, subject to certain conditions, allows Consumers to adjust future rates to collect or refund the change in marginal revenue by class arising from the difference between base sales per customer established in the order and weather-adjusted sales per customer. The order denied Consumers’ request to implement a gas uncollectible expense tracking mechanism and Pension Plan and OPEB equalization mechanisms. In August 2010, Consumers filed an application to refund $11 million to customers, beginning in January 2011. Consumers cannot predict the financial impact or outcome of this gas rate case.

In August 2010, Consumers filed an application with the MPSC seeking an annual increase in revenue of $55 million based on an 11 percent authorized return on equity. The filing requested recovery for investments made to enhance safety, system reliability, and operational efficiencies that improve service to customers. The following table details the components of the requested increase in revenue:


In Millions
Components of the increase in revenue

Investment in rate base	$	30
Recovery of operating and maintenance costs		16

Impact of sales declines		4

Total	$	55

Gas Depreciation: In September 2009, the MPSC ordered Consumers to adopt certain standard retirement units by January 1, 2010. Consumers estimates that the use of these standard retirement units will increase maintenance expense, and recovery of that expense, by $10 million annually. In May 2010, as ordered by the MPSC, Consumers implemented the new standard retirement units concurrently with the final rates approved in its gas rate case.

(a)		In conjunction with the September 2010 issuance of the 4.25 percent senior notes, CMS Energy exercised its mandatory conversion rights for all of its outstanding 4.50 percent cumulative convertible preferred stock. Also in September 2010, holders tendered 633,971 shares of the 4.50 percent cumulative convertible preferred stock for voluntary conversion. In October 2010, CMS Energy used the majority of the net proceeds from the issuance of the senior notes to pay the $226 million cash portion of the conversion value and issued 13,110,733 shares of its common stock to pay the common stock portion of the conversion value.

In September 2010, Consumers executed a bond purchase agreement and issued, in an October 2010 private placement, $50 million of 2.60 percent FMBs due 2015, $100 million of 3.21 percent FMBs due 2017, $100 million of 3.77 percent FMBs due 2020, and $50 million of 4.97 percent FMBs due 2040. In conjunction with this issuance, in September 2010 Consumers called $137 million of 5.65 percent FMBs due 2035 for redemption, which occurred in October 2010.

Revolving Credit Facilities: The following secured revolving credit facilities with banks were available at September 30, 2010:

(a)		CMS Energy’s average borrowings during the nine months ended September 30, 2010, totaled $1 million, with a weighted-average annual interest rate of 1.0 percent, at LIBOR plus 0.75 percent.

(b)		Secured revolving letter of credit facility.

Short-term Borrowings: Under Consumers’ revolving accounts receivable sales program, Consumers may transfer up to $250 million of accounts receivable, subject to certain eligibility requirements. Effective January 1, 2010, transactions entered into under this program are accounted for as secured borrowings rather than as sales. For additional details, see Note 1, New Accounting Standards. At September 30, 2010, $250 million of accounts receivable were eligible for transfer, and no accounts receivable had been transferred under the program.

Consumers’ average short-term borrowings during the nine months ended September 30, 2010, totaled $1 million, with a weighted average annual interest rate of 0.2 percent.

Contingently Convertible Securities: At September 30, 2010, the significant terms of CMS Energy’s contingently convertible securities were as follows:



			Outstanding		Adjusted		Adjusted
Security	Maturity		(In Millions)		Conversion Price		Trigger Price

3.375% senior notes (a)		2023	$	131	$	9.67	$	11.60
2.875% senior notes (a)		2024		288		13.36		16.03
5.50% senior notes		2029		173		14.46		18.80


(a)		During 20 of the last 30 trading days ended September 30, 2010, the adjusted trigger prices were met for these securities and, as a result, the securities are convertible at the option of the security holders for the three months ending December 31, 2010.

During the three months ended September 30, 2010, no other trigger price contingencies were met that would have allowed the holders of the convertible securities to convert the securities to cash and equity.

In July 2010, holders tendered 250,000 shares of 4.50 percent cumulative convertible preferred stock for voluntary conversion. The conversion value per share of preferred stock was $89.43. CMS Energy issued 614,940 shares of its common stock and paid $13 million cash on settlement.

In July 2010, holders tendered $8 million principal amount of 3.375 percent senior notes for voluntary conversion. The conversion value per $1,000 principal amount of convertible note was $1,666.57. CMS Energy issued 331,008 shares of its common stock and paid $8 million cash on settlement.

In September 2010, holders tendered 633,971 shares of 4.50 percent cumulative convertible preferred stock for voluntary conversion. The average conversion value per share of preferred stock was $103.88. CMS Energy issued 1,834,456 shares of its common stock and paid $32 million cash on settlement of these conversions in October 2010.

In September 2010, CMS Energy exercised its mandatory conversion rights for all of its outstanding 4.50 percent cumulative convertible preferred stock. The conversion value per share of preferred stock was $104.22. CMS Energy issued 11,276,277 shares of its common stock and paid $194 million on settlement of these conversions in October 2010.

As of September 30, 2010, CMS Energy reclassified preferred stock of $226 million to a current liability.

Dividend Restrictions: Under provisions of CMS Energy’s senior notes indenture, at September 30, 2010, payment of common stock dividends by CMS Energy was limited to $981 million.

Under the provisions of its articles of incorporation, at September 30, 2010, Consumers had $425 million of unrestricted retained earnings available to pay common stock dividends to CMS Energy. Provisions of the Federal Power Act and the Natural Gas Act appear to restrict dividends payable by Consumers to the amount of Consumers’ retained earnings. Several decisions from FERC suggest that under a variety of circumstances common stock dividends from Consumers would not be limited to amounts in Consumers’ retained earnings. Any decision by Consumers to pay common stock dividends in excess of retained earnings would be based on specific facts and circumstances and would result only after a formal regulatory filing process.

For the nine months ended September 30, 2010, CMS Energy received $259 million of common stock dividends from Consumers.

Basic	$	1.38		$	0.83

Contingently Convertible Securities: When CMS Energy has earnings from continuing operations, its contingently convertible securities dilute EPS to the extent that the conversion value of a security, which is based on the average market price of CMS Energy’s common stock, exceeds the principal value of that security.

In September 2010, CMS Energy exercised its mandatory conversion rights for all of its outstanding 4.50 percent cumulative convertible preferred stock and charged unamortized issuance costs of $8 million to Charge for Deferred Issuance Costs on Preferred Stock, in Accumulated Deficit, which reduced Net Income Available to Common Stockholders, on its Consolidated Statements of Income. In October 2010, CMS Energy issued 11,276,277 shares of its common stock upon conversion. For additional details on contingently convertible securities, see Note 5, Financings.

Stock Options and Warrants: For each of the three and nine months ended September 30, 2010, outstanding options to purchase 0.4 million shares of CMS Energy common stock had no impact on diluted EPS, since the exercise price was greater than the average market price of CMS Energy common stock. These stock options have the potential to dilute EPS in the future.

Non-vested Stock Awards: CMS Energy’s non-vested stock awards are composed of participating and non-participating securities. The participating securities accrue cash dividends when common stockholders receive dividends. Since the recipient is not required to return the dividends to CMS Energy if the recipient forfeits the award, the non-vested stock awards are considered participating securities. As such, the participating non-vested stock awards were included in the computation of basic EPS. The non-participating securities accrue stock dividends that vest concurrently with the stock award. If the recipient forfeits the award, the stock dividends accrued on the non-participating securities are also forfeited. Accordingly, the non-participating awards and stock dividends were included in the computation of diluted EPS, but not basic EPS.

Convertible Debentures: For the nine months ended September 30, 2010 and for each of the three and nine months ended September 30, 2009, there was no impact on diluted EPS from CMS Energy’s 7.75 percent convertible subordinated debentures. Using the if-converted method, the debentures would have:

	•		increased the numerator of diluted EPS by less than $1 million for the three months ended September 30, 2009, from an assumed reduction of interest expense, net of tax;

	•		increased the denominator of diluted EPS by 0.7 million shares for the three months ended September 30, 2009;

	•		increased the numerator of diluted EPS by $1 million for the nine months ended September 30, 2010, and by $4 million for the nine months ended September 30, 2009, from an assumed reduction of interest expense, net of tax; and

	•		increased the denominator of diluted EPS by 0.7 million shares for the nine months ended September 30, 2010, and by 3.0 million shares for the nine months ended September 30, 2009.

CMS Energy can revoke the conversion rights if certain conditions are met.

7: FINANCIAL INSTRUMENTS

The carrying amounts of CMS Energy’s and Consumers’ cash, cash equivalents, current accounts and notes receivable, short-term investments, and current liabilities approximate their fair values because of their short-term nature. The cost or carrying amounts and fair values of CMS Energy’s and Consumers’ long-term financial instruments were as follows:

(b)		Includes current portion of long-term debt of $173 million at September 30, 2010 and $343 million at December 31, 2009.

Notes receivable, net consist of EnerBank’s fixed-rate installment loans. EnerBank estimates the fair value of these loans using a discounted cash flows technique that incorporates current market interest rates as well as assumptions about the remaining life of the loans and credit risk. Fair values for impaired loans are estimated using discounted cash flows or underlying collateral values.

CMS Energy and Consumers estimate the fair value of their long-term debt using quoted prices from market trades of the debt, if available. In the absence of quoted prices, CMS Energy and Consumers

calculate market yields and prices for the debt using a matrix method that incorporates market data for similarly rated debt. Depending on the information available, other valuation techniques may be used that rely on internal assumptions and models. For its convertible securities, CMS Energy incorporates, as appropriate, information on the market prices of CMS Energy’s common stock.

The effects of third-party credit enhancements are excluded from the fair value measurements of long-term debt. At September 30, 2010, CMS Energy’s long-term debt included $239 million principal amount that was supported by third-party insurance or other credit enhancements. This entire principal amount was at Consumers. At December 31, 2009, CMS Energy’s long-term debt included $286 million principal amount that was supported by third-party insurance or other credit enhancements. Of this amount, $271 million principal amount was at Consumers.

8: DERIVATIVE INSTRUMENTS

In order to limit exposure to certain market risks, primarily changes in commodity prices, interest rates, and foreign exchange rates, CMS Energy and Consumers may enter into various risk management contracts, such as forward contracts, futures, options, and swaps. In entering into these contracts, they follow established policies and procedures under the direction of an executive oversight committee consisting of senior management representatives and a risk committee consisting of business unit managers. Neither CMS Energy nor Consumers enters into any derivatives for trading purposes.

The contracts used to manage market risks may qualify as derivative instruments. If a contract is a derivative and does not qualify for the normal purchases and sales exception, the contract is recorded on the balance sheet at its fair value. Each reporting period, the resulting asset or liability is adjusted to reflect any change in the fair value of the contract. Since none of CMS Energy’s or Consumers’ derivatives have been designated as accounting hedges, all changes in fair value are reported in earnings. For a discussion of how CMS Energy and Consumers determine the fair value of their derivatives, see Note 2, Fair Value Measurements.

Commodity Price Risk: In order to support ongoing operations, CMS Energy and Consumers enter into contracts for the future purchase and sale of various commodities, such as electricity, natural gas, and coal. These forward contracts are generally long-term in nature and result in physical delivery of the commodity at a contracted price. Most of these contracts are not subject to derivative accounting 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.

CMS Energy’s and Consumers’ coal purchase contracts are not derivatives because there is not an active market for the coal they purchase. If an active market for coal develops in the future, some of these contracts may qualify as derivatives. For Consumers, which is subject to regulatory accounting, the resulting fair value gains and losses would be offset by changes in regulatory assets and liabilities and would not affect net income. No other subsidiaries of CMS Energy enter into coal purchase contracts.

CMS ERM has not designated its contracts to purchase and sell electricity and natural gas as normal purchases and sales and, therefore, CMS Energy accounts for those contracts as derivatives. To manage commodity price risks associated with these forward purchase and sale contracts, CMS ERM uses various financial instruments, such as futures, options, and swaps. At September 30, 2010, CMS ERM held a forward contract for the physical sale of 709 GWh of electricity through 2015 on behalf of one of CMS Energy’s non-utility generating plants. CMS ERM also held futures contracts through 2011 as an economic hedge of 27 percent of the generating plant’s natural gas requirements needed to serve a steam sales contract, for a total of 0.3 bcf of natural gas. In its role as a marketer of natural gas for third-party producers, CMS ERM held forward contracts to purchase 1.3 bcf and sell 1.0 bcf of natural gas through 2010 and a financial contract to sell 1.0 bcf of natural gas as an economic hedge of gas storage sales in 2011. At September 30, 2010, CMS ERM held financial contracts through 2010 as an economic hedge against tolling arrangements with a purchase of 168 GWh of electricity and a sale of 1.1 bcf of gas. At September 30, 2010, CMS ERM also held an option to sell 612 GWh of electricity and, as an economic hedge, contracts to purchase 0.4 bcf of natural gas.

(d)		At December 31, 2009, CMS Energy’s derivatives included an interest rate collar held by Grayling as an economic hedge of the variable interest rate charged on its outstanding revenue bonds. Effective January 1, 2010, CMS Energy deconsolidated Grayling. CMS Energy reflected its share of the loss on the interest rate collar, which was less than $1 million at September 30, 2010, in Income (loss) from equity method investees on its Consolidated Statements of Income. For additional details about the deconsolidation of Grayling, see Note 11, Variable Interest Entities.

The following tables summarize the effect of CMS Energy’s and Consumers’ derivative instruments on their Consolidated Statements of Income:

(a)		This derivative loss relates to a foreign-exchange forward contract that CMS Energy settled in January 2009.

At September 30, 2010, none of CMS Energy’s derivative liabilities was subject to credit-risk-related contingency features. At December 31, 2009, CMS Energy’s derivative liabilities subject to credit-risk-related contingent features were less than $1 million.

Credit Risk: CMS Energy’s swaps, options, and forward contracts contain credit risk, which is the risk that a counterparty will fail to meet its contractual obligations. CMS Energy reduces this risk through established policies and procedures. CMS Energy assesses credit quality by considering credit ratings, financial condition, and other available information for counterparties. A credit limit is established for each counterparty based on the evaluation of their credit quality. Exposure to potential loss under each contract is monitored and action is taken when appropriate.

CMS ERM enters into contracts primarily with companies in the electric and gas industry. This industry concentration may have a positive or negative impact on CMS Energy’s exposure to credit risk based on how similar changes in economic conditions, the weather, or other conditions affect these counterparties. CMS ERM reduces its credit risk exposure by using industry-standard agreements that allow for netting positive and negative exposures associated with the same counterparty. Typically, these agreements also allow each party to demand adequate assurance of future performance from the other party, when there is reason to do so.

The following table illustrates CMS Energy’s exposure to potential losses at September 30, 2010, if each counterparty within this industry concentration failed to meet its contractual obligations. This table includes contracts accounted for as derivatives. It does not include trade accounts receivable, derivative contracts that qualify for the normal purchases and sales exception, or other contracts that CMS Energy does not account for as derivatives.

CMS Energy does not expect a material adverse effect on its Consolidated Balance Sheets and Consolidated Statements of Income as a result of counterparty nonperformance, given CMS Energy’s credit policies, current exposures, and credit reserves.

9: RETIREMENT BENEFITS

CMS Energy’s and Consumers’ expected long-term rate of return on Pension Plan assets is eight percent. For the nine months ended September 30, 2010, the actual return on Pension Plan assets was 8.8 percent, and for 2009 the actual return was 21 percent. The expected rate of return is an assumption about long-term asset performance that CMS Energy and Consumers review annually for reasonableness and appropriateness.

In February 2010, the MPSC issued an order in Consumers’ GCR case that allowed Consumers to collect a one-time surcharge under a Pension Plan and OPEB equalization mechanism. For the nine months ended September 30, 2010, Consumers collected $2 million of Pension Plan and $1 million of OPEB surcharge revenue in gas rates. Consumers’ collection of the equalization mechanism surcharge had no impact on net income for the nine months ended September 30, 2010.

In April 2010, the MPSC issued an order in Consumers’ 2007 PSCR case that allowed Consumers to collect a one-time surcharge under a Pension Plan and OPEB equalization mechanism. For the nine months ended September 30, 2010, Consumers collected $21 million of Pension Plan and $6 million of OPEB surcharge revenue in electric rates. Consumers’ collection of the equalization mechanism surcharge had no impact on net income for the nine months ended September 30, 2010.

In July 2010, the MPSC issued an order in Consumers’ 2008 PSCR case that allowed Consumers to collect a one-time surcharge under a Pension Plan and OPEB equalization mechanism. For the nine months ended September 30, 2010, Consumers collected $8 million of Pension Plan surcharge revenue and refunded $1 million of OPEB surcharge revenue in electric rates. Consumers’ collection of the equalization mechanism surcharge had no impact on net income for the nine months ended September 30, 2010.

CMS Energy and Consumers remeasured their OPEB obligations at April 30, 2010 to incorporate the effects of a new collective bargaining agreement reached between the Union and Consumers. The OPEB plan remeasurement decreased CMS Energy’s OPEB liability by $95 million, OPEB regulatory asset by $93 million, and AOCL by $2 million, and will result in a decrease in benefit costs of $14 million for 2010. The OPEB plan remeasurement decreased Consumers’ OPEB liability and OPEB regulatory asset by $93 million each, and will result in a decrease in benefit costs of $13 million for 2010. With the plan remeasurement, the discount rate was reduced from 6.0 percent at December 31, 2009 to 5.85 percent at April 30, 2010.

In March 2010, CMS Energy contributed $100 million to its pension fund, which included a contribution of $97 million by Consumers. In February 2010, CMS Energy contributed $17 million to its SERP fund, which included a contribution of $11 million by Consumers.

10: INCOME TAXES

The actual income tax expense on income from continuing operations, excluding income attributable to noncontrolling interests, differs from the amount computed by applying the statutory U.S. federal income tax rate as follows:

Nine months ended September 30	2010			2009

Income from continuing operations before income taxes	$	539		$	326

Other, net		1			1

Income tax expense	$	207		$	165

Effective tax rate		36.8	%		37.8	%

For taxable years beginning after December 31, 2012, the Health Care Acts repeal the tax deduction for the portion of health care costs that are reimbursed by the Medicare Part D subsidy. To reflect the law change, CMS Energy and Consumers decreased their deferred tax asset balances by $68 million, with CMS Energy recognizing deferred tax expense of $3 million and Consumers recognizing an increase to net regulatory tax assets of $65 million (not including the effects of ratemaking tax gross-ups). Therefore, this legislation had no effect on Consumers’ net income for the nine months ended September 30, 2010.

11: VARIABLE INTEREST ENTITIES

Entities that are VIEs must be consolidated if the reporting entity determines that it has a controlling financial interest. The entity that is required to consolidate the VIE is called the primary beneficiary. Variable interests are contractual, ownership, or other interests in an entity that change as the fair value of the VIE’s net assets, excluding variable interests, changes. An entity is considered to be a VIE when its capital is insufficient to permit it to finance its activities without additional subordinated financial support or its equity investors, as a group, lack the characteristics of having a controlling financial interest.

Effective January 1, 2010, the accounting standards for consolidation of VIEs were amended. The most significant amendment changed the criteria for identifying the primary beneficiary. Under the amended standard, the primary beneficiary is the entity that has both (1) the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and (2) the obligation to absorb losses of the VIE that could potentially be significant to the VIE.

As a result of adopting this amendment, effective January 1, 2010, CMS Energy has consolidated CMS Energy Trust I and deconsolidated three partnerships that it had previously consolidated.

CMS Energy has consolidated CMS Energy Trust I because CMS Energy is the variable interest holder that designed the entity and, through the design, has the power to direct the activities of CMS Energy Trust I that most significantly impact the trust’s economic performance. Through its guarantee, CMS Energy also has the obligation to absorb losses of CMS Energy Trust I. The sole assets of the trust consist of notes payable by CMS Energy, and the sole liabilities of the trust consist of Trust Preferred Securities. Upon consolidation, CMS Energy reduced its equity method investment by $5 million and its Long-term debt by $34 million. CMS Energy also recorded a $29 million liability for the mandatorily redeemable preferred securities issued by the trust. No gain or loss was recognized on the consolidation of CMS Energy Trust I.

CMS Energy has deconsolidated T.E.S. Filer City, Grayling, and Genesee because CMS Energy determined that power is shared among unrelated parties, and that no one party has the power to direct the activities that most significantly impact the entities’ economic performance. The partners must agree on all major decisions for each of the partnerships. As a result, CMS Energy is not the primary beneficiary of these partnerships.

The following table provides information about these partnerships:



	Nature of
Name (Ownership Interest)	the Entity	Financing of Partnership

T.E.S. Filer City (50%)	Coal-fueled power generator	Non-recourse long-term debt that matured in December 2007.

Grayling (50%)	Wood waste- fueled power generator	Sale of revenue bonds that mature in November 2012 and bear interest at variable rates. The debt is recourse to the partnership, but not the individual partners, and secured by a letter of credit equal to the outstanding balance.

Genesee (50%)	Wood waste- fueled power generator	Sale of revenue bonds that mature in 2021 and bear interest at fixed rates. The debt is non-recourse to the partnership and secured by a CMS Energy guarantee capped at $3 million annually.

CMS Energy has operating and management contracts with Grayling and Genesee, and Consumers is the primary purchaser of power from each partnership through long-term PPAs. Consumers also has reduced dispatch agreements with Grayling and Genesee, which allow these facilities to be dispatched based on the market price of wood waste. This results in fuel cost savings that each partnership shares with Consumers’ customers.

CMS Energy’s investment in these partnerships is included in Investments on the Consolidated Balance Sheets in the amount of $49 million as of September 30, 2010. The partnerships were consolidated at December 31, 2009. Total assets of the partnerships were $189 million and total liabilities were $92 million at December 31, 2009. The partnerships had third-party debt obligations totaling $70 million at December 31, 2009. Plant, property, and equipment serving as collateral for these obligations had a carrying value of $137 million at December 31, 2009. The creditors of these partnerships do not have recourse to the general credit of CMS Energy or Consumers, except through outstanding letters of credit of $2 million and a guarantee of $3 million annually. CMS Energy has deferred collections on certain receivables owed by Genesee. CMS Energy’s maximum exposure to loss from these receivables is $6 million. Consumers has not provided any financial or other support during the periods presented that was not previously contractually required.

12: REPORTABLE SEGMENTS

Reportable segments consist of business units defined by the products and services they offer. CMS Energy and Consumers evaluate the performance of each segment based on its contribution to net income available to CMS Energy’s common stockholders.
