MANAGEMENT’S DISCUSSION AND ANALYSIS

This MD&A is a combined report of CMS Energy and Consumers.

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 independent power producer. 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 and operates 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.

CMS Energy’s business approach has emphasized the key elements depicted below:

Safe, Excellent Operations

The safety and security of employees, customers, and the general public remain a priority of CMS Energy and Consumers. Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture. These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions. From 2007 to 2010, Consumers achieved a 63 percent reduction in the annual number of recordable safety incidents.

Customer Value

Consumers is undertaking a number of initiatives that reflect its intensified customer focus. Consumers’ planned investments in reliability are aimed at improving safety, reducing customer outage frequency, reducing repetitive outages, and increasing customer satisfaction. Consumers’ productivity improvements are expected to help keep annual base rate increases (excluding PSCR and GCR charges) at or below the average rate of inflation. Consumers considers these and other aspects of its customer value initiative to be important to its success.

Utility Investment

Consumers expects to make capital investments of $6.6 billion from 2012 through 2016, 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 other existing units.

Renewable energy projects are a major component of Consumers’ planned capital investments. Consumers expects to spend $500 million on renewable energy investments from 2012 through 2016. The 2008 Energy Law requires that at least ten percent of Consumers’ electric sales volume come from renewable energy sources by 2015, and it includes requirements for specific capacity additions. Consumers has historically included renewable resources as part of its portfolio, with about five percent of its present power supply coming from such renewable sources as hydroelectric, landfill gas, biomass, and wind. In May 2011, the MPSC issued an order approving Consumers’ amended renewable energy plan, with slight modifications. The amended plan reduces the renewable energy surcharge that will be billed to customers in the future by an annual amount of $54 million, reflecting lower-than-anticipated costs to comply with renewable energy requirements. In October 2011, Consumers filed an application for the biennial review and approval of its renewable energy plan. The plan further reduces the renewable energy surcharge that will be billed to customers by an annual amount of $3 million.

In February 2011, Consumers and Detroit Edison together announced an $800 million maintenance and upgrade project at their jointly owned Ludington pumped-storage plant. The project, scheduled to begin in 2013 and extend through 2019, is expected to increase the capacity of Ludington by 16 percent, from its present level of 1,872 MW to about 2,172 MW, and increase the plant’s efficiency by five percent. Consumers expects its share of the project cost to total $400 million.

Consumers’ Smart Grid program, with an estimated total project capital cost of $750 million, also represents a major capital investment. The full-scale deployment of advanced metering infrastructure is planned to begin in the second half of 2012 and to continue through 2019. Consumers will have spent $160 million through 2011 on its Smart Grid program, and expects to spend an additional $260 million, following a phased approach, from 2012 through 2016.

Two additional major investment areas for Consumers are environmental spending and reliability improvements. Consumers expects its environmental investments to total $1.5 billion and its investments in system reliability to total $1.2 billion from 2012 through 2016.

Regulation

Regulatory matters are a key aspect of CMS Energy’s and Consumers’ businesses, particularly Consumers’ rate cases and regulatory proceedings before the MPSC. In September 2011, Michigan Governor Rick Snyder appointed John D. Quackenbush to replace retiring MPSC member Monica Martinez. John D. Quackenbush will serve as chair of the MPSC and former chair Orjiakor Isiogu will continue to serve as a member.

Recent important regulatory events and developments are summarized below.

	•		Gas Rate Cases: In May 2011, the MPSC approved a settlement agreement in Consumers’ 2010 gas rate case, authorizing a $31 million annual increase in gas rates, based on a 10.5 percent authorized return on equity. In September 2011, Consumers filed a new general gas rate case seeking an annual rate increase of $49 million, based on a 10.7 percent authorized return on equity.

	•		Electric Rate Case: In June 2011, Consumers filed a new general electric rate case seeking an annual rate increase of $195 million, based on a 10.7 percent authorized return on equity.

	•		Revenue Decoupling Mechanisms: In March 2011, Consumers filed its first reconciliation of the electric decoupling mechanism, requesting recovery of $27 million from customers for the period December 2009 through November 2010. This mechanism, presently authorized under the MPSC’s 2010 electric rate order through November 2011, allows Consumers to adjust future electric rates to compensate for changes in sales volumes resulting from the difference between the level of average sales per customer adopted in the order and actual average sales per customer, subject to certain conditions.

			In September 2011, Consumers filed its first reconciliation of the gas revenue decoupling mechanism, requesting recovery of $16 million from customers for the period June 2010 through May 2011. This mechanism, presently authorized under the MPSC’s 2010 gas rate case order, allows Consumers to adjust future gas rates to compensate for changes in sales volumes resulting from the difference between the level of average sales per customer adopted in the order and actual average weather-adjusted sales per customer, subject to certain conditions.

	•		DOE Settlement: In July 2011, Consumers entered into an agreement with the DOE to settle its claims related to the DOE’s failure to accept spent nuclear fuel. In September 2011, Consumers filed an application with the MPSC regarding the allocation of the $120 million settlement amount.

Environmental regulation is another area of importance for CMS Energy and Consumers, and they are monitoring numerous legislative and regulatory initiatives to regulate greenhouse gases, as well as related litigation. The EPA has taken steps to regulate greenhouse gases under the Clean Air Act, and is expected to propose guidelines for states to regulate greenhouse gas emissions from new and existing sources.

During 2010, the EPA issued various proposals for regulating PCBs, CCBs, sulfur dioxide, and nitrogen oxides. Additionally, in March 2011, the EPA proposed a hazardous air pollutant rule that would establish MACT emission standards for mercury and other hazardous air pollutants. Under the proposed rule, some coal-fueled electric generating units would require additional controls for hazardous air pollutants. Also in March 2011, the EPA issued a proposed rule to regulate existing electric generating plant cooling water intake systems. In July 2011, the EPA finalized the CSAPR, which requires

Michigan and 26 other states to improve air quality by reducing power plant emissions that allegedly contribute to ground-level ozone and fine particle pollution in other downwind states. This rule, which replaces CAIR, mandates emission reductions beginning in 2012. CMS Energy and Consumers are monitoring developments regarding MACT emission standards for potential effects on their operations and are continuing to assess the impact and cost of complying with the CSAPR.

Financial Performance in 2011 and Beyond

For the three months ended September 30, 2011, CMS Energy’s net income available to common stockholders was $139 million, and diluted earnings per share were $0.53. This compares with net income available to common stockholders of $134 million and diluted earnings per share of $0.53 for the three months ended September 30, 2010. For the nine months ended September 30, 2011, CMS Energy’s net income available to common stockholders was $374 million, and diluted earnings per share were $1.43. This compares with net income available to common stockholders of $299 million and diluted earnings per share of $1.19 for the nine months ended September 30, 2010. Among the factors contributing to CMS Energy’s improved performance for the nine months ended September 30, 2011 were benefits from electric and gas rate orders and increased gas deliveries, offset partially by higher depreciation, property taxes, and distribution and service restoration costs. A tax benefit resulting from the enactment of the MCIT in May 2011 was offset by the absence, in 2011, of an insurance settlement recovery recorded in 2010.

A more detailed discussion of the factors affecting CMS Energy’s and Consumers’ performance can be found in the “Results of Operations” section that follows this Executive Overview.

CMS Energy believes that economic conditions in Michigan are improving. Although Michigan’s economy continues to be affected by the recession and its impact on the state’s automotive industry and by high unemployment rates, there are indications that the recession has eased in Michigan. Consumers expects its electric sales to increase by more than one percent annually through 2016, driven largely by the continued rise in industrial production. Consumers is projecting that its gas sales will remain stable through 2016, due largely to energy efficiency and conservation.

As Consumers seeks to continue to receive fair and timely regulatory treatment, delivering customer value will remain a key strategic priority. To keep costs down for its utility customers, Consumers has set goals to achieve further annual productivity improvements. Additionally, Consumers will strive to give priority to capital investments that increase customer value or lower costs.

Consumers expects to continue to have sufficient capacity to fund its investment-based growth plans. CMS Energy also expects its sources of liquidity to remain sufficient to meet its cash requirements. CMS Energy and Consumers will continue to monitor developments in the financial and credit markets, as well as government policy responses to those developments, for potential implications for their businesses and their future financial needs.

Electric deliveries and rate increases: For the three months ended September 30, 2011, electric delivery revenues increased $3 million compared with 2010. This variance was due to additional revenues of $17 million resulting from a November 2010 rate increase and a $14 million increase in sales to Consumers’ industrial customers, offset partially by the impact of customers switching from demand rates to energy-only rates. These increases were also offset largely by a $28 million decrease in surcharge revenues and related reserves. Overall, deliveries to end-use customers were 10.4 billion kWh in 2011 and 10.5 billion kWh in 2010.

For the nine months ended September 30, 2011, electric delivery revenues increased $5 million compared with 2010. This variance was due to additional revenues of $83 million resulting from a November 2010 rate increase and a $9 million increase in other revenues, offset largely by the absence, in 2011, of $87 million of surcharges in 2010 to recover retirement benefit expenses and certain regulatory assets. Overall, deliveries to end-use customers were 28.7 billion kWh in 2011 and 28.6 billion kWh in 2010.

Power supply costs and related revenue: For the nine months ended September 30, 2011, PSCR revenue increased $10 million compared with 2010. This increase was due to the absence, in 2011, of a disallowance in 2010 of certain power supply costs.

Other income, net of expenses: For the three months ended September 30, 2011, other income decreased $5 million compared with 2010, and for the nine months ended September 30, 2011, other income decreased $12 million compared with 2010. These decreases were due primarily to a reduction in the return on certain regulatory assets as a result of their declining balances.

Maintenance and other operating expenses: For the three months ended September 30, 2011, maintenance and other operating expenses increased $14 million compared with 2010. This variance was due to $6 million of higher service restoration costs and $14 million of higher forestry and other operating expenses. These increases were offset partially by the absence, in 2011, of $6 million of retirement benefit expenses that were recovered in revenues in 2010.

For the nine months ended September 30, 2011, maintenance and other operating expenses increased $13 million compared with 2010. This variance was due to $27 million of higher service restoration costs, caused by a series of unusually severe storms in 2011, and $24 million of higher forestry, plant maintenance, and other operating expenses. These increases were offset partially by the absence, in 2011,

of $32 million of retirement benefit expenses that were recovered in revenues in 2010 and $6 million of voluntary separation plan expenses incurred in 2010.

Depreciation and amortization: For the three months ended September 30, 2011, depreciation and amortization expense decreased $14 million compared with 2010, and for the nine months ended September 30, 2011, depreciation and amortization expense decreased $38 million compared with 2010. These decreases were due to lower amortization expense on certain regulatory assets, offset partially by higher depreciation expense from increased plant in service.

General taxes: For the three months ended September 30, 2011, general taxes decreased $6 million compared with 2010, reflecting the impact of a final Michigan single business tax assessment for the years 2004 through 2007 that resulted in a tax deficiency less than the amount previously accrued.

Interest charges: For the nine months ended September 30, 2011, interest charges decreased $8 million compared with 2010, primarily from the absence, in 2011, of interest expense on a Michigan use tax assessment.

Income taxes: For the nine months ended September 30, 2011, income taxes increased $11 million compared with 2010, reflecting higher electric utility earnings in 2011.

Gas deliveries and rate increases: For the three months ended September 30, 2011, gas delivery revenues increased $3 million compared with 2010. This increase was due primarily to the May 2011 rate increase. Gas deliveries, including miscellaneous transportation to end-use customers, were 25.5 bcf in 2011, a decrease of 0.5 bcf, or 1.9 percent, compared with 2010.

For the nine months ended September 30, 2011, gas delivery revenues increased $55 million compared with 2010. This increase reflected higher customer usage, of which $38 million was due to colder weather in 2011. Gas deliveries, including miscellaneous transportation to end-use customers, were 205.0 bcf in 2011, an increase of 23.8 bcf, or 13.1 percent, compared with 2010.

Other income, net of expenses: For the three months ended September 30, 2011, other income decreased $2 million compared with 2010, and for the nine months ended September 30, 2011, other income decreased $6 million compared with 2010. These decreases were due primarily to a reduction in interest income related to secured lending agreements.

For the nine months ended September 30, 2011, maintenance and other operating expenses increased $9 million compared with 2010. The increase was due to $16 million of higher distribution operating expenses, offset partially by the absence, in 2011, of $3 million of retirement benefit expenses that were recovered in revenues in 2010 and $4 million of voluntary separation plan expenses incurred in 2010.

Depreciation and amortization: For the nine months ended September 30, 2011, depreciation and amortization expense increased $6 million compared with 2010, due to higher depreciation expense from increased plant in service.

General taxes: For the three months ended September 30, 2011, general taxes decreased $3 million compared with 2010, reflecting the impact of a final Michigan single business tax assessment for the years 2004 through 2007 that resulted in a tax deficiency less than the amount previously accrued.

Income taxes: For the three months ended September 30, 2011, income taxes decreased $5 million compared with 2010, reflecting lower gas utility earnings in 2011.

For the nine months ended September 30, 2011, income taxes increased $14 million compared with 2010, reflecting higher gas utility earnings in 2011.

For the three months ended September 30, 2011, net income of the enterprises segment decreased $5 million compared with 2010, due primarily to lower after-tax mark-to-market gains of $3 million.

For the nine months ended September 30, 2011, net income of the enterprises segment decreased $15 million compared with 2010, due to the absence, in 2011, of a $31 million insurance settlement recovery in 2010, lower electric revenues of $8 million, and lower mark-to-market gains of $5 million. These after-tax decreases were offset partially by a $28 million income tax benefit resulting from the enactment of the MCIT in May 2011.

For the three months ended September 30, 2011, corporate interest and other net expenses decreased $14 million compared with 2010, due primarily to the absence, in 2011, of an $8 million after-tax charge in 2010 for deferred issuance costs on conversion of preferred stock. Also contributing to the decrease were a $4 million benefit from the impact of a final Michigan single business tax assessment for the years

2004 through 2007 that resulted in a tax deficiency less than the amount previously accrued and lower fixed charges in 2011.

For the nine months ended September 30, 2011, corporate interest and other net expenses decreased $26 million compared with 2010, due to the absence, in 2011, of an $8 million after-tax charge in 2010 for deferred issuance costs on conversion of preferred stock and an $8 million after-tax decrease in fixed charges in 2011. Also contributing to the decrease were lower income tax expense resulting partially from the enactment of the MCIT in May 2011 and a $4 million benefit from the impact of a final Michigan single business tax assessment for the years 2004 through 2007 that resulted in a tax deficiency less than the amount previously accrued.

Discontinued Operations

For the nine months ended September 30, 2011, income of $2 million was recorded from discontinued operations due to a legal settlement, compared with a loss from discontinued operations of $17 million in 2010 related to prior asset sales.

CASH POSITION, INVESTING, AND FINANCING

At September 30, 2011, CMS Energy had $623 million of consolidated cash and cash equivalents and $29 million of restricted cash and cash equivalents. At September 30, 2011, Consumers had $373 million of consolidated cash and cash equivalents and $28 million of restricted cash and cash equivalents.

For the nine months ended September 30, 2011, net cash provided by operating activities at CMS Energy increased $197 million compared with 2010. The increase was due primarily to the changes in Consumers’ cash provided by operating activities described in the following paragraph.

For the nine months ended September 30, 2011, net cash provided by operating activities at Consumers increased $345 million compared with 2010. The increase was due primarily to the absence of Pension Plan contributions in 2011, increased collections of accounts receivable, and the absence, in 2011, of refunds paid to customers in 2010.

Investing Activities

For the nine months ended September 30, 2011, net cash used in investing activities increased $26 million at CMS Energy compared with 2010. This variance was due to an increase in capital expenditures and other investing activities, including CMS Energy’s contribution of $27 million to its SERP fund. These changes were offset partially by the absence, in 2011, of the cash effect of deconsolidating certain partnerships in 2010.

For the nine months ended September 30, 2011, net cash used in investing activities increased $43 million at Consumers compared with 2010. The variance was due to an increase in asset retirement costs and other investing activities, including Consumers’ contribution of $20 million to its SERP fund.

For the nine months ended September 30, 2011, net cash used in financing activities at CMS Energy increased $404 million compared to 2010. The change was due to a decrease in net proceeds from borrowings and higher dividend payments in 2011.

For the nine months ended September 30, 2011, net cash used in financing activities at Consumers increased $194 million compared with 2010. The change was due to an increase in net retirements of debt, a lower stockholder’s contribution from CMS Energy, and higher dividend payments in 2011.

CAPITAL RESOURCES AND LIQUIDITY

CMS Energy uses dividends from its subsidiaries and external financing and capital transactions to invest in its utility and non-utility businesses, retire debt, pay dividends, and fund its other obligations. The ability of CMS Energy’s subsidiaries, including Consumers, to pay dividends to CMS Energy depends upon each subsidiary’s revenues, earnings, cash needs, and other factors. In addition, Consumers’ ability to pay dividends may be restricted by certain terms included in its articles of incorporation, by provisions under the Federal Power Act and the Natural Gas Act, and by FERC requirements. For additional details on Consumers’ dividend restrictions, see Note 5, Financings, “Dividend Restrictions.” For the nine months ended September 30, 2011, Consumers paid $292 million in common stock dividends to CMS Energy.

Consumers uses cash flows generated from operations and external financing transactions, as well as stockholder’s contributions from CMS Energy, to fund capital expenditures, retire debt, pay dividends, contribute to its employee benefit plans, and fund its other obligations.

CMS Energy’s and Consumers’ access to the financial and capital markets depends on their credit ratings and on market conditions. As evidenced by past financing transactions, CMS Energy and Consumers have had ready access to these markets and, barring major market dislocations or disruptions, they expect to continue to have such access. If access to these markets were to become diminished or otherwise restricted, however, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending. CMS Energy and Consumers had the following secured revolving credit facilities available at September 30, 2011:

This facility has a five-year term and replaces CMS Energy’s revolving credit facility that was set to expire in 2012. Obligations under this facility are secured by Consumers common stock.

² On March 31, 2011, Consumers entered into a $500 million secured revolving credit facility with a consortium of banks. This facility has a five-year term and replaces Consumers’ revolving credit facility that was set to expire in 2012.

³ Obligations under this facility are secured by FMBs of Consumers.

⁴ Secured revolving letter of credit facility.

CMS Energy and Consumers use these credit facilities for general working capital purposes and to issue letters of credit. An additional source of liquidity is Consumers’ revolving accounts receivable sales program, which allows it to transfer up to $250 million of accounts receivable as a secured borrowing. At September 30, 2011, $250 million of accounts receivable were eligible for transfer under this program.

CMS Energy’s $550 million revolving credit agreement specifies a maximum debt-to-EBITDA ratio, as defined therein. Consumers’ $500 million revolving credit agreement specifies a maximum debt-to-capital ratio, as defined therein. CMS Energy and Consumers were each in compliance with these limits as of September 30, 2011, as presented in the following table:

Components of CMS Energy’s and Consumers’ cash management plan include controlling operating expenses and capital expenditures and evaluating market conditions for financing and refinancing opportunities. 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 fund their contractual obligations for 2011 and beyond.

Off-Balance-Sheet Arrangements

CMS Energy, Consumers, and certain of their subsidiaries also 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 the short-term and long-term energy needs of its customers through:

	•		energy efficiency;

	•		demand management;

	•		expanded use of renewable energy;

	•		development of new power plants;

	•		pursuit of additional PPAs to complement existing generating sources;

	•		continued operation of existing units; and

	•		potential retirement or mothballing of older generating units.

In 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 usage and 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 has been monitoring customer usage and demand, fuel and power prices, and other market conditions, and has not set a timetable for a future decision about the project. Although the likelihood that the plant will be constructed has diminished significantly, in July 2011 the MDEQ granted Consumers an extension of the project’s air permit, which is being challenged by two environmental groups. Consumers’ alternatives to constructing the proposed coal-fueled plant include constructing new gas-fueled generation, relying on additional market purchases, and continued operation of several existing generating units.

Renewable Energy Plan: Consumers’ renewable energy plan details how Consumers will meet REC and capacity standards prescribed by the 2008 Energy Law. This law requires Consumers to obtain RECs in an amount equal to at least ten percent of its electric sales volume (estimated to be 3.5 million RECs annually) by 2015. RECs represent proof that the associated electricity was generated from a renewable energy resource. Under its renewable energy plan, Consumers expects to secure its renewable energy requirement each year with a combination of newly generated RECs and previously generated RECs carried over from prior years. At September 30, 2011, the combination of these sources represented 84 percent of Consumers’ 2015 REC requirement.

The 2008 Energy Law 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. To meet its renewable capacity requirements, Consumers expects to add more than 500 MW of owned or contracted renewable capacity by 2015. Through September 2011, Consumers has contracted for the purchase of 297 MW of nameplate capacity from renewable energy suppliers, which represents 59 percent of the 2015 renewable capacity requirement.

Consumers has secured more than 81,000 acres of land easements in Michigan’s Huron, Mason, and Tuscola Counties for the potential development of wind generation, and is now collecting wind speed and other meteorological data at those sites. Consumers has entered into construction and supply contracts as well as a contract to purchase wind turbine generators for the construction of Lake Winds Energy Park, a 100-MW wind park in Mason County, which Consumers expects to be operational in late 2012. In July 2011, the Mason County Planning Commission voted in favor of granting a special land use permit

for the construction of Lake Winds Energy Park. The actions of the Mason County Planning Commission have been upheld by the Mason County Zoning Board of Appeals. The permit has now been appealed to the Mason County Circuit Court. Consumers will also continue development of Cross Winds Energy Park, its 150-MW wind park in Tuscola County, scheduled for operation by late 2015, as well as seek other opportunities for wind generation development in support of the renewable capacity standards.

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 believes economic conditions are improving, and expects weather-adjusted electric deliveries to increase in 2011 by 1.5 percent compared with 2010.

Consumers expects average electric delivery growth of more than one percent annually over the next five years. This increase reflects growth in electric demand, offset partially 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, expansion, or contraction of manufacturing facilities, population trends, and housing activity.

The MPSC’s 2009 electric rate case order authorized Consumers to implement an electric revenue decoupling mechanism, subject to certain conditions. This decoupling mechanism, which was extended through November 2011 in the MPSC’s 2010 electric rate case order, allows Consumers to adjust future electric rates to compensate for changes in sales volumes resulting from the difference between the level of average sales per customer adopted in the order and actual average sales per customer. This mechanism mitigates the impacts of weather fluctuations, energy efficiency, and conservation on Consumers’ electric utility revenue.

Electric ROA: The Customer Choice Act allows all of Consumers’ electric customers to buy electric generation service from Consumers or from an alternative electric supplier. The 2008 Energy Law revised the Customer Choice Act by limiting alternative electric supply to ten percent of Consumers’ weather-adjusted retail sales of the preceding calendar year. At September 30, 2011, electric deliveries under the ROA program were at the ten percent limit and alternative electric suppliers were providing 792 MW of generation service to ROA customers. Based on 2010 weather-adjusted retail sales, Consumers expects 2011 electric deliveries under the ROA program to be at a similar level to 2010.

Electric Transmission: In July 2011, FERC issued an order in a rulemaking proceeding concerning regional electric transmission planning and cost allocations. In August 2011, Consumers and several other electric utilities filed a joint petition seeking clarification/rehearing of FERC’s July order and opposing the allocation methodology.

In a related matter, in July 2010, MISO filed a tariff revision with FERC proposing a cost allocation methodology for a new category of transmission projects. In December 2010, FERC approved MISO’s cost allocation proposal. Under this tariff revision, the cost of these new transmission projects will be spread proportionally across the Midwest Energy Market. Consumers believes that Michigan customers will bear additional costs under MISO’s tariff without receiving comparable benefits from these projects. In January 2011, Consumers, along with the Michigan Attorney General, ABATE, Detroit Edison, the Michigan Municipal Electric Association, and the Michigan Public Power Agency, filed a request for rehearing with FERC, opposing the allocation methodology in the MISO tariff revision. In October 2011, FERC denied this request for rehearing. Consumers expects to continue to recover transmission expenses, including those associated with the MISO tariff revision, through the PSCR process.

Electric Rate Matters: Rate matters are critical to Consumers’ electric utility business. See Note 4, Regulatory Matters, “Consumers’ Electric Utility” for details on the following electric rate matters:

	•		electric rate cases;

	•		PSCR;

	•		electric revenue decoupling mechanism;

	•		uncollectible expense tracking mechanism;

	•		electric operation and maintenance expenditures show-cause order;

	•		Big Rock decommissioning;

	•		renewable energy plan;

	•		energy optimization plan; and

	•		electric depreciation.

Electric Environmental Estimates: Consumers’ operations are subject to various state and federal environmental laws and regulations. Consumers estimates that it will incur expenditures of $1.6 billion from 2011 through 2018 to continue to comply with the Clean Air Act, Clean Water Act, and numerous state and federal environmental 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:

Air Quality: In December 2008, a court decision remanded CAIR back to the EPA. Until the EPA finalized a new rule, CAIR remained in effect. In July 2011, the EPA released CSAPR, a final replacement rule for CAIR, which requires Michigan and 26 other states to improve air quality by reducing power plant emissions that allegedly contribute to ground level ozone and fine particle pollution in other downwind states. This rule mandates emission reductions beginning in 2012. In a separate but related regulatory action, the EPA also issued a supplemental notice of proposed rulemaking requiring certain states, including Michigan, to reduce nitrogen oxides emissions during the summer months under the CSAPR ozone-season control program. If this supplemental proposal were finalized, it would bring the total number of states covered under CSAPR to 28.

In March 2011, the EPA proposed MACT emission standards for electric generating units, based on Section 112 of the Clean Air Act. Under the proposed rule, some coal-fueled and oil-fueled electric generating units would require additional controls for hazardous air pollutants. Existing units must meet the standards generally within three to four years of issuance of the final rule. Although numerous parties, including the State of Michigan, have sought to extend the deadline, the EPA is scheduled to issue the final rule in December 2011.

Presently, Consumers’ strategy to comply with CSAPR, and with MACT emission standards for electric generating units in its proposed form, involves the installation of state-of-the-art emission control equipment; however, Consumers continues to evaluate CSAPR and MACT emission standards for electric generating units in conjunction with other EPA rulemakings, litigation and congressional action. These rules could result in:

	•		additional or accelerated environmental compliance costs related to Consumers’ coal-fueled and oil-fueled power plants;

	•		a change in the fuel mix at coal-fueled and oil-fueled power plants;

	•		changes in how certain plants are used; and

	•		the retirement of some or all of Consumers’ older, smaller generating units or the temporary suspension of their operations.

The MDEQ renewed and issued the B.C. Cobb Renewable Operating Permit in August 2011 after an extensive review and a public comment period. In October 2011, the Sierra Club and the Natural Resources Defense Council filed a petition with the EPA to object to the MDEQ’s issuance of the state Renewable Operating Permit, alleging that the facility is not in compliance with certain provisions of the

Clean Air Act, including NSR and Title V. The EPA could either deny the petition outright or grant the petition and remand the matter to the MDEQ for further action. Consumers believes these claims are baseless, but is unable to predict the outcome of this petition.

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 2010, the EPA released its Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule, which sets limits for greenhouse gas emissions that define when permits are required for new and existing industrial facilities under NSR PSD and Title V Operating Permit programs. Numerous parties have challenged this rule in the U.S Court of Appeals for the D.C. Circuit, and Consumers is monitoring this litigation. Consumers does not expect to incur significant expenditures to comply with this rule.

In December 2010, the EPA entered into a settlement agreement with certain states and environmental groups wherein in September 2011 the EPA was to propose new source performance standards for greenhouse gases at new and modified power plants pursuant to Section 111(b) of the Clean Air Act. The EPA did not meet the September 2011 deadline and has not yet announced a new schedule for issuance of the standards. The EPA is also expected to propose emissions guidelines for the states to regulate greenhouse gas emissions from existing generating units under Section 111(d) of the Clean Air Act. Under the expected schedule, states will need to submit plans to the EPA within nine months of issuance of the final rule and guidelines. Consumers will continue to monitor activity from this settlement and any proposed new source performance standards regulations.

Litigation, as well as federal laws, EPA regulations regarding greenhouse gases, or similar treaties, state laws, or rules, if enacted or ratified, could require Consumers to replace equipment, install additional emission control equipment, 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, which would result in a significant increase in the amount of coal ash requiring costly disposal. Additionally, if the cost of upgrading existing coal ash disposal areas to meet hazardous waste landfill standards were to become economically prohibitive, existing coal ash disposal areas could close, requiring Consumers to find costly alternative arrangements for disposal. Consumers is unable to predict the impacts from this wide range of possible outcomes, but significant expenditures are likely.

Water: In March 2011, the EPA issued a proposed rule to regulate existing electric generating plant cooling water intake systems under Section 316(b) of the Clean Water Act aimed at reducing alleged harmful impacts on fish and shellfish. Consumers is evaluating this proposed rule and its potential impacts on Consumers’ plants. A final rule is expected in July 2012.

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. To comply with this proposed rule, Consumers could incur substantial costs associated with existing electrical equipment that could contain PCBs.

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

Consumers’ Gas Utility Business Outlook and Uncertainties

Gas Deliveries: Consumers believes economic conditions in Michigan are improving, and expects weather-adjusted gas deliveries to increase in 2011 by three percent compared with 2010. Over the next five years, Consumers expects average gas deliveries to remain stable. Actual delivery levels from year to year may vary from this trend due to:

	•		fluctuations in weather;

	•		use by independent power producers;

	•		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 impacts greater or less than predicted.

A decoupling mechanism was authorized by the MPSC in Consumers’ 2009 gas rate case, subject to certain conditions. This mechanism, which was extended in the MPSC’s 2010 gas rate order, allows Consumers to adjust future gas rates to compensate for changes in sales volumes resulting from the difference between the level of average sales per customer adopted in the order and actual average weather-adjusted sales per customer. The mechanism does not provide rate adjustments for changes in sales volumes arising from weather fluctuations. This mechanism mitigates the impacts of energy efficiency programs, conservation, and changes in economic conditions on Consumers’ gas utility revenue.

Gas Rate Matters: Rate matters are critical to Consumers’ gas utility business. See Note 4, Regulatory Matters, “Consumers’ Gas Utility” for details on Consumers’ gas rate case, GCR, and gas revenue decoupling mechanism.

Gas Pipeline Safety: In response to the natural gas pipeline explosion that occurred in San Bruno, California in September 2010 and other recent events, 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 both transmission and distribution pipelines. The proposed bills contain provisions mandating:

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

	•		redefinition of “high consequence areas”

	•		increased civil penalties;

	•		prescribed notification and on-site incident response times;

	•		plans for safe management and replacement of cast iron pipelines;

	•		consideration of seismic activity;

	•		verification of maximum allowable operating pressure of all pipelines; 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 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 response activity 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.”

Consumers’ Other Outlook and Uncertainties

Smart Grid: Consumers’ grid modernization effort continues, with the recent selection of a vendor that will provide smart electric meters and a cellular communications network to allow Consumers to transmit and receive electric usage information from customers’ homes and businesses. Smart meters are designed to allow customers to monitor and manage their energy usage, which should help reduce demand during critical peak times, resulting in lower peak capacity requirements. The installation of smart meters should also provide operational benefits to Consumers. Consumers intends to use a phased implementation approach, beginning deployment in the second half of 2012 and continuing through 2019. Consumers is also considering installing communication modules on gas meters in areas where Consumers provides both electricity and natural gas to customers.

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, or 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

EnerBank: EnerBank, a wholly owned subsidiary of CMS Capital, is a Utah state-chartered, FDIC-insured industrial bank providing unsecured home improvement loans. EnerBank represented one percent of CMS Energy’s net assets at September 30, 2011, and two percent of CMS Energy’s net income available to common stockholders for the nine months ended September 30, 2011. The carrying value of EnerBank’s loan portfolio was $439 million at September 30, 2011. Its loan portfolio was funded primarily by deposit liabilities of $422 million. Twelve-month rolling average default rates on loans held by EnerBank have declined from 1.4 percent at December 31, 2010 to 1.0 percent at September 30, 2011. CMS Energy is required to ensure that EnerBank remains well capitalized.

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, Regulatory Matters.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

These interim consolidated financial statements have been prepared by CMS Energy and Consumers in accordance with GAAP 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 GAAP. 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 the 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 2010 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

New Accounting Standards Not Yet Effective

ASU 2011-05, Presentation of Comprehensive Income: This standard, effective January 1, 2012 for CMS Energy and Consumers, eliminates the option of reporting other comprehensive income and its components on the statement of changes in equity. Presently, both CMS Energy and Consumers use this option for their consolidated financial statements. Under the standard, entities will be required to present either a single continuous statement of comprehensive income, containing both net income and components of other comprehensive income, or two separate consecutive statements. This standard will affect only the presentation of comprehensive income in CMS Energy’s and Consumers’ consolidated financial statements.

ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs: This standard, effective January 1, 2012 for CMS Energy and Consumers, is the result of a joint project of the Financial Accounting Standards Board and the International Accounting Standards Board. The primary objective of the standard is to ensure that fair value has the same meaning under GAAP and International Financial Reporting Standards and to establish common fair value measurement guidance in the two sets of standards. The standard does not change the overall fair value model in GAAP, but it amends various fair value principles and establishes additional disclosure requirements. CMS Energy and Consumers are evaluating this standard, but they do not expect it to have a significant impact on their consolidated financial statements.

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

Presented in the following table are CMS Energy’s and Consumers’ assets and liabilities, by level within the fair value hierarchy, reported at fair value on a recurring basis at September 30, 2011:

⁵ At December 31, 2010, Consumers’ assets classified as Level 3 represented one percent of Consumers’ total assets measured at fair value.

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, repurchase agreements collateralized by U.S. Treasury notes, and highly rated, short-term corporate debt securities.

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 net asset values 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 net asset value, 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 valued using Level 2 inputs, including commodity market prices, interest rates, credit ratings, default rates, and market-based seasonality factors. CMS Energy and Consumers have classified certain derivatives as Level 3 since the fair value measurements incorporate pricing assumptions that cannot be observed or confirmed through market transactions.

The most significant derivatives classified as Level 3 are an electricity sales agreement held by CMS ERM and FTRs held by Consumers. At December 31, 2010 and in prior periods, quoted electricity prices were not available for the entire term of the electricity sales agreement held by CMS ERM, and a proprietary forward pricing model was used to determine fair value. At September 30, 2011, quoted prices at the nearest active market were available for the entire term of the agreement. The agreement, however, remains classified as Level 3 since the pricing differential between the nearest active market in Ohio and the delivery point in Michigan cannot be confirmed with observable market transactions. There is no quoted pricing information for FTRs held by Consumers. Consumers determines the fair value of FTRs based on Consumers’ average historical settlements.

For fair values other than Level 1 prices, CMS Energy and Consumers may incorporate adjustments for the risk of nonperformance as deemed appropriate. For derivative assets, a credit adjustment is applied against the asset based on the published default rate for the credit rating assigned 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 available to market participants. If the internal rating is comparable to credit ratings published by independent rating agencies, the resulting credit adjustment is classified as Level 2. If the internal rating is outside of the range of ratings given by 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. CMS Energy and Consumers monitor market conditions and may incorporate other data, such as credit default swap rates, in determining adjustments for credit risk as warranted. For additional details about derivative contracts, see Note 8, Derivative Instruments.

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. The fair value was determined based on a discounted cash flow technique. CMS Energy had no other nonrecurring fair value measurements and Consumers had no nonrecurring fair value measurements during the nine months ended September 30, 2010.

3: CONTINGENCIES AND COMMITMENTS

CMS Energy and Consumers are involved in various matters that give rise to contingent liabilities. Depending on the specific issues, the resolution of these contingencies could have a material effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. In their disclosures of these matters, CMS Energy and Consumers provide an estimate of the possible loss or range of loss when such an estimate can be made. Disclosures that state that CMS Energy or Consumers cannot predict the outcome of a matter indicate that they are unable to estimate a possible loss or range of loss for the matter.

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 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, and Wisconsin. The following provides more detail on these proceedings:

•

In 2005, CMS Energy, CMS MST, and CMS Field Services were named 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 the defendants engaged in a scheme to violate the Kansas Restraint of Trade Act. The plaintiffs are seeking statutory full consideration damages consisting of the full consideration paid by plaintiffs for natural gas allegedly purchased from defendants.

	•		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 laws.

	•		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 2006. Defendants, including CMS Energy, CMS Field Services, and CMS MST, are alleged to have violated the Colorado Antitrust Act of 1992. 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. 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 complaint in the U.S. District Court for the Eastern District of Michigan. In 2010, the MDL judge issued an opinion and order granting the CMS Energy defendants’ motion to dismiss the Michigan complaint on statute-of-limitations grounds and all CMS Energy defendants have been dismissed from the Arandell (Michigan) action.

	•		Another class action complaint, Newpage Wisconsin System v. CMS ERM, et al., was filed in 2009 in circuit court in Wood County, Wisconsin, against CMS Energy, CMS ERM, Cantera Gas Company, and others. 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 CMS Energy, CMS MST, CMS Field Services, and others. 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 in 2000 and 2001.

After removal to federal court, all of the cases described above were transferred to the MDL. CMS Energy was dismissed from the Learjet, Heartland, and J.P. Morgan cases in 2009, but other CMS Energy defendants remained parties. All CMS Energy defendants were dismissed from the Breckenridge case in 2009. In 2010, CMS Energy and Cantera Gas Company were dismissed from the Newpage case and the Arandell (Wisconsin) case was reinstated against CMS ERM. In July 2011, all claims against remaining CMS Energy defendants in the MDL cases were dismissed based on FERC preemption. Plaintiffs have filed appeals in all of the cases.

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. If the outcome after appeals is unfavorable, these cases could have a material adverse impact on CMS Energy’s liquidity, 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 MDEQ, 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 Administrative Order on Consent 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 completed in 2010.

In May 2011, CMS Energy received approval from the EPA on a revised scope of remedies that CMS Energy had submitted in December 2010. CMS Energy is presently in negotiations with the MDEQ to finalize an agreement that will identify the remaining final remedies at the site. In December 2010, the MDEQ issued an NPDES permit that authorizes CMS Land to discharge treated leachate into Little Traverse Bay. This permit requires renewal every five years. Discharge of treated leachate under the permit commenced at the East Park portion of the Bay Harbor site in October 2011. Additionally, CMS Land has committed to investigate the potential for a deep injection well on the Bay Harbor site as an alternative long-term solution to the leachate disposal issue. In 2008, the MDEQ and the EPA granted permits for CMS Land or its wholly owned subsidiary, Beeland Group LLC, to construct and operate an off-site 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.

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. In October 2010, CMS Land and other parties 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 the EPA’s response costs incurred at the Bay Harbor site. CMS Land communicated to the EPA in November 2010 that it does not believe that this is a valid claim.

CMS Land and CMS Capital, the MDEQ, the EPA, and other parties continue to negotiate the long-term remedy for the Bay Harbor site, including:

	•		the disposal of leachate;

	•		the capping and excavation of CKD;

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

	•		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 $224 million, which includes accretion expense. At September 30, 2011, CMS Energy had a recorded liability of $82 million for its remaining obligations. CMS Energy calculated this liability based on discounted projected costs, using a discount rate of 4.34 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 at December 31, 2010. The undiscounted amount of the remaining obligation is $103 million. CMS Energy expects to pay $8 million during the remainder of 2011, $18 million in 2012, $8 million in 2013, $5 million in 2014, $4 million in 2015, 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 complete the present long-term water disposal strategy at a reasonable cost;

	•		delays in implementing the present long-term water disposal strategy;

	•		requirements to alter the present long-term water disposal strategy upon expiration of the NPDES permit if the MDEQ or EPA identify a more suitable alternative;

	•		an increase in the number of contamination areas;

	•		different remediation techniques;

	•		the nature and extent of contamination;

	•		inability to reach agreement with the MDEQ 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. Although a liability for its present estimate of remaining response activity costs has been recorded, CMS Energy cannot predict the ultimate financial impact or outcome of this matter.

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 2002 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, plus interest, 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 indicated through a request for arbitration in October 2011 that it still intends to pursue its claim. CMS Energy is evaluating this request and 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. Historically, Consumers has generally 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, 2011, 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. In November 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party at the Kalamazoo River Superfund site. The notification claimed that the EPA has reason to believe Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site. Consumers responded to the EPA in December 2010, stating that it has no information showing that it disposed of PCBs or arranged for disposal or treatment of PCB-containing material at portions of the site and requesting further information from the EPA before Consumers would commit to perform or finance cleanup activities at the site. In April 2011, Consumers received a follow-up letter from the EPA requesting that Consumers, as a potentially responsible party at the Kalamazoo River Superfund site, agree to participate in a removal action plan along with several other companies for an area of lower Portage Creek. The letter also indicated that under Sections 106 and 107 of Superfund, Consumers may be liable for reimbursement of the EPA’s costs and potential penalties for noncompliance with any unilateral order that the EPA may issue requiring performance under the removal

action plan. All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability. In August 2011, the EPA announced that it would proceed with the removal action plan and would continue to pursue potentially responsible parties to perform or pay for some or all of the work. The EPA has provided limited information regarding Consumers’ potential responsibility for contamination at the site and has not yet given an indication of the share of any cleanup costs for which Consumers could be held responsible. Consumers continues to investigate the EPA’s claim that it disposed of PCBs or arranged for disposal or treatment of PCB-containing material at portions of the site. Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river.

Based on its experience, Consumers estimates that its share of the total liability for other 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, 2011, Consumers had a recorded liability of $2 million for its share of the total liability at these sites, 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, the 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 review under the NSR. 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 Projects, and/or pay fines. Additionally, Consumers would need to assess the viability of continuing operations at certain plants. The potential costs relating to these matters could be material and the extent of cost recovery cannot be reasonably estimated. Although Consumers cannot predict the financial impact or outcome of these matters, 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: The matters discussed in this section relate to Consumers’ previously owned nuclear generating plants.

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.

In July 2011, Consumers entered into an agreement with the DOE to settle its claims for $120 million. In September 2011, Consumers filed an application with the MPSC regarding the regulatory treatment of the settlement amount. For further information, see Note 4, Regulatory Matters, “Consumers’ Electric Utility — Big Rock Decommissioning.”

As part of the agreement with the DOE, Consumers settled its liability to the DOE to fund the disposal of spent nuclear fuel used at Palisades and Big Rock before 1983. This liability, which totaled $163 million, comprised $44 million collected from customers for spent nuclear disposal fees and $119 million of interest accrued on those fees, and was to be paid no later than when the DOE began accepting delivery of spent nuclear fuel. CMS Energy and Consumers classified the liability as long-term debt in their consolidated balance sheets.

Following the settlement, Consumers terminated its letter of credit to Entergy, which Consumers had provided as security for its retained obligation to the DOE in connection with its sale of Palisades and the Big Rock ISFSI to Entergy in 2007.

In its November 2010 electric rate order, the MPSC had directed Consumers to establish an independent trust fund for the amount payable to the DOE. Following its settlement with the DOE, Consumers petitioned the MPSC to relieve it of the obligation to fund the trust.

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, 2011, Consumers estimated its undiscounted remaining remediation and other response activity costs to be between $28 million and $42 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, 2011, Consumers had a recorded liability of $28 million and a regulatory asset of $54 million that included $26 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 $5 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.

¹ The majority of this amount arises from stock and asset sale 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.

² At September 30, 2011, 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.

Presented in the following table is additional information regarding CMS Energy’s and Consumers’ guarantees:



Guarantee Description	How Guarantee Arose	Events That Would Require Performance

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

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

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

Consumers
Guarantees and indemnity obligations	Normal operating activity	Nonperformance or claims made by third party under a related contract

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

Michigan Single Business Tax: The State of Michigan completed its audit of CMS Energy’s and Consumers’ combined Michigan single business tax returns for the years 2004 through 2007, and identified a tax deficiency that was less than the amount CMS Energy had previously accrued. As a

result, in September 2011 CMS Energy recognized a reduction in general taxes of $17 million, which included $10 million recognized by Consumers.

Other: In addition to the matters disclosed in this note and Note 4, Regulatory 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 matters, federal and state taxes, rates, licensing, employment, 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 condition, or liquidity.

4: REGULATORY 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 CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings.

Consumers’ Electric Utility

Electric Rate Cases: The MPSC, in its 2010 electric rate case order, authorized Consumers to increase its rates by $146 million annually, $4 million less than the rate increase self-implemented by Consumers in July 2010. In June 2011, the MPSC approved a settlement agreement, finding that no refund of self-implemented rates to customers is required.

In June 2011, Consumers filed an application with the MPSC seeking an annual rate increase of $195 million, based on a 10.7 percent authorized return on equity. The filing requested authority to recover new investment in system reliability, environmental compliance, and technology enhancements. Presented in the following table are the components of the requested rate increase:


	In Millions
Components of the rate increase

Investment in rate base	$	81
Depreciation and property taxes		70
Impact of sales declines		50
Impact of reduced funding for customer assistance programs¹		13
Reduced operating and maintenance costs		(17	)
Cost of capital		(2	)

Total	$	195

¹ Consumers projects electric uncollectible expense to increase by $13 million in 2012 due to an anticipated reduction in federal funding for customer assistance programs. Due to the uncertainty surrounding federal funding for such programs and the resulting impact on uncollectible expense, Consumers also requested that the MPSC approve an uncollectible expense true-up mechanism.

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

In October 2011, the administrative law judge recommended that the MPSC approve Consumers’ 2011 PSCR Plan, with minor exceptions.

In September 2011, Consumers submitted its 2012 PSCR plan to the MPSC. In accordance with its proposed plan, Consumers expects to self-implement the 2012 PSCR charge beginning in January 2012.

PSCR Reconciliation: Presented in the following table is the PSCR reconciliation filing pending with the MPSC:

In June 2011, the MPSC issued an order approving Consumers’ 2009 PSCR reconciliation, as modified by the order, and authorized Consumers to include an underrecovery of $31 million in its 2010 PSCR reconciliation.

Electric Revenue Decoupling Mechanism: The MPSC’s 2009 electric rate case order authorized Consumers to implement an electric revenue decoupling mechanism, subject to certain conditions. This decoupling mechanism, which was extended through November 2011 in the 2010 electric rate case order, allows Consumers to adjust future electric rates to compensate for changes in sales volumes resulting from the difference between the level of average sales per customer adopted in the order and actual average sales per customer. Various parties have filed appeals concerning the electric decoupling mechanism.

In March 2011, Consumers filed its first reconciliation of the electric revenue decoupling mechanism with the MPSC, requesting recovery of $27 million from customers for the period December 2009 through November 2010. The MPSC Staff and intervenors are opposing this recovery.

At September 30, 2011, Consumers had a $55 million non-current regulatory asset recorded for electric decoupling, which included the $27 million balance referred to above.

Uncollectible Expense Tracking Mechanism: In March 2011, Consumers filed its reconciliation of the uncollectible expense tracking mechanism with the MPSC, requesting recovery of $3 million from customers for November 2009 through November 2010, the entire period of the tracker. The uncollectible expense tracking mechanism, authorized by the MPSC in its 2009 electric rate order, allowed future rates to be adjusted to collect or refund 80 percent of the difference between the level of electric uncollectible expense included in rates and actual uncollectible expense. During 2009, various parties filed appeals concerning the uncollectible expense tracking mechanism. In its 2010 electric rate order, the MPSC terminated the uncollectible expense tracking mechanism as of November 2010.

Electric Operation and Maintenance Expenditures Show-Cause Order: In 2005, 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. In 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 had not refunded this amount to customers. 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 June 2011, the MPSC found that Consumers violated the 2005 order, but that customers were not affected significantly by the violation. The MPSC levied a $65,200 penalty on Consumers, but concluded that no refund was required.

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. 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 a decommissioning trust fund. The MPSC agreed that Consumers was entitled to recover $44 million of decommissioning costs, 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. Consumers completed this refund in January 2011. 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 paid $30 million to Entergy to assume ownership and responsibility for the Big Rock ISFSI. Consumers also incurred $55 million at Big Rock for nuclear fuel storage costs as a result of the DOE’s failure to accept spent nuclear fuel. Consumers has an $85 million regulatory asset recorded on its consolidated balance sheets for these costs. Consumers had filed a complaint against the DOE in 2002 for its failure to accept spent nuclear fuel, and in July 2011, Consumers entered into an agreement with the DOE to settle its claims for $120 million. In September 2011, Consumers filed an application with the MPSC requesting authority to utilize $85 million of the DOE settlement amount as recovery of its regulatory asset, and to refund to customers $23 million previously collected through rates for spent nuclear fuel costs. If the MPSC concludes that Consumers may retain any portion of the remaining $12 million of the DOE settlement amount, Consumers will recognize that amount in earnings. For further information, see Note 3, Contingencies and Commitments, “Consumers’ Electric Utility Contingencies — Nuclear Matters.”

Renewable Energy Plan: In 2010, Consumers filed with the MPSC its first annual report and reconciliation for its renewable energy plan, requesting approval of Consumers’ reconciliation of renewable energy plan costs for 2009. In June 2011, the administrative law judge issued a proposal for decision, recommending that the MPSC issue an order finding that Consumers met its 2009 renewable portfolio standards and that actual 2009 renewable energy expenses and revenues fell within MPSC-authorized levels. The administrative law judge also recommended, however, that the MPSC exclude from recovery through the renewable surcharge $3 million of capital expenditures, along with related carrying costs, that Consumers incurred prior to enactment of the 2008 Energy Law.

Consumers filed its second annual report and reconciliation with the MPSC in June 2011, requesting approval of its reconciliation of renewable energy plan costs for 2010.

In May 2011, the MPSC issued an order approving Consumers’ amended renewable energy plan, with slight modifications. The amended plan reduces the renewable energy surcharge that will be billed to customers by an annual amount of $54 million. The reduction is a result of lower-than-anticipated costs to comply with the renewable energy requirements prescribed by the 2008 Energy Law.

In October 2011, Consumers filed an application for the biennial review and approval of its renewable energy plan. The plan further reduces the renewable energy surcharge that will be billed to customers by an annual amount of $3 million.

Energy Optimization Plan: In May 2011, the MPSC issued an order approving Consumers’ reconciliation of energy optimization plan costs for 2009. The MPSC also authorized Consumers to collect $6 million from customers as an incentive payment for exceeding savings targets under both its gas and electric energy optimization plans during 2009. Consumers will collect the incentive over 12 months beginning June 2011.

In April 2011, Consumers filed with the MPSC its second annual report and reconciliation for its energy optimization plan, requesting approval of Consumers’ reconciliation of energy optimization plan costs for 2010.

Consumers also requested approval to collect $8 million from customers as an incentive payment for exceeding savings targets under both its gas and electric energy optimization plans during 2010.

As one of the conditions to the continuation of the electric and gas decoupling mechanisms, Consumers must exceed the statutory savings targets for 2012 through 2015 specified in the 2008 Energy Law. In August 2011, Consumers filed an amended energy optimization plan with the MPSC, requesting approval of the additional spending necessary to exceed these savings targets.

Electric Depreciation: In June 2011, the MPSC approved a settlement agreement in Consumers’ February 2010 electric depreciation case, authorizing a $19 million increase in annual depreciation expense. The new depreciation rates will go into effect with a final order in Consumers’ next electric rate case.

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. In October 2011, a settlement agreement among all parties was submitted to the MPSC for approval.

Consumers’ Gas Utility

Gas Rate Case: In August 2010, Consumers filed an application with the MPSC seeking an annual 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.

Consumers filed testimony and exhibits with the MPSC in January 2011, supporting a self-implemented annual gas rate increase of $48 million, subject to refund with interest. In February, Consumers filed a letter with the MPSC reducing the proposed self-implemented increase to $29 million. The MPSC then issued an order delaying Consumers’ self-implementation in order to give other parties to the proceeding an opportunity to respond to Consumers’ revised self-implementation filing.

In May 2011, the MPSC approved a partial settlement agreement authorizing Consumers to increase its rates by $31 million annually, based on a 10.5 percent authorized return on equity. Matters not addressed in the settlement agreement included the decoupling mechanism, the Smart Grid program, and contributions to the low-income and energy efficiency fund. Presented in the following table are the components of the rate increase authorized by the MPSC and the rate increase originally requested by Consumers:


In Millions
				Increase Originally
	Increase Authorized			Requested by
Components of the rate increase	by the MPSC			Consumers		Difference

Investment in rate base	$	29		$	30	$	(1	)
Impact of sales declines		15			4		11
Operating and maintenance costs		2			16		(14	)
Cost of capital		(15	)		5		(20	)

Total	$	31		$	55	$	(24	)

In August 2011, the MPSC authorized the continuation of the decoupling mechanism and the collection of low-income and energy efficiency funds, but denied recovery of costs associated with the Smart Grid program related to Consumers’ gas utility. Consumers filed a petition for rehearing in this case, stating that disallowance of Smart Grid costs was contrary to the settlement agreement approved in May 2011. In its petition, Consumers recognized the MPSC’s concerns regarding the Smart Grid program related to the gas utility and stated that it would remove all costs associated with the gas Smart Grid program from its next general rate case application. In October 2011, the MPSC granted Consumers’ petition for

rehearing, allowing Consumers to recover costs that the gas utility has incurred associated with the Smart Grid program.

In September 2011, Consumers filed an application with the MPSC seeking an annual rate increase of $49 million based on a 10.7 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. Presented in the following table are the components of the requested rate increase:

Total	$	49

¹ Consumers projects gas uncollectible expense to increase by $19 million in 2012 due to an anticipated reduction in federal and state funding for customer assistance programs. Due to the uncertainty surrounding federal and state funding for such programs and the resulting impact on uncollectible expense, Consumers also requested that the MPSC approve an uncollectible expense true-up mechanism.

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 Plan: In December 2010, Consumers submitted its 2011-2012 GCR plan to the MPSC. In accordance with its proposed plan, Consumers self-implemented the 2011-2012 GCR charge beginning in April 2011. In September 2011, the administrative law judge recommended that the MPSC approve Consumers’ 2011-2012 GCR plan, with certain adjustments to its fixed-price purchase guidelines.

GCR Reconciliations: Presented in the following table are the GCR reconciliation filings pending with the MPSC:

Gas Revenue Decoupling Mechanism: The MPSC’s 2009 gas rate case order authorized Consumers to implement a gas revenue decoupling mechanism, subject to certain conditions. This decoupling mechanism, which was extended in the 2010 gas rate case order, allows Consumers to adjust future gas rates to compensate for changes in sales volumes resulting from the difference between the level of average sales per customer adopted in the order and actual average weather-adjusted sales per customer. In September 2011, Consumers filed its first reconciliation of the gas revenue decoupling mechanism with the MPSC, requesting recovery of $16 million from customers for the period June 2010 through May 2011. At September 30, 2011, Consumers had a $16 million non-current regulatory asset recorded for gas decoupling.

¹ In May 2011, Consumers utilized the Michigan Strategic Fund for the issuance of $68 million and $35 million of tax-exempt Michigan Strategic Fund Variable Rate Limited Obligation Revenue Bonds. The initial interest rate, which resets weekly, was 0.26 percent for the $68 million bond issuance and 0.28 percent for the $35 million bond issuance. The bonds, which are backed by letters of credit and collateralized by FMBs, are subject to optional tender by the holders that would result in remarketing. Consumers used the proceeds to redeem $103 million of tax-exempt bonds in May 2011.

² In July 2011, Consumers settled its nuclear fuel disposal liability with the DOE. For additional details, see the “Consumers’ Electric Utility Contingencies — Nuclear Matters” section in Note 3, Contingencies and Commitments.

In September 2011, CMS Energy called $50 million principal amount of its 6.3 percent senior notes due in 2012 for redemption in October 2011.

³ Obligations under this facility are secured by FMBs of Consumers.

⁴ 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. These transactions are accounted for as short-term secured borrowings. At September 30, 2011, $250 million of accounts receivable were eligible for transfer, and no accounts receivable had been transferred under the program. During the nine months ended September 30, 2011, Consumers had no borrowings under this program.

Contingently Convertible Securities: Presented in the following table are the significant terms of CMS Energy’s contingently convertible securities at September 30, 2011:



			Outstanding		Adjusted Conversion		Adjusted

Dividend Restrictions: Under provisions of CMS Energy’s senior notes indenture, at September 30, 2011, payment of common stock dividends by CMS Energy was limited to $1.2 billion.

Under the provisions of its articles of incorporation, at September 30, 2011, Consumers had $510 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, 2011, CMS Energy received $292 million of common stock dividends from Consumers.

Issuance of Common Stock: On June 15, 2011, CMS Energy entered into a continuous equity offering program under which CMS Energy may sell, from time to time in “at the market” offerings, common stock having an aggregate sales price of up to $50 million. In June 2011, under this program, CMS Energy issued 762,925 shares of common stock at an average price of $19.66 per share, resulting in net proceeds of $15 million.

Diluted		0.53		0.53		1.42		1.26

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 common stock, exceeds the principal value of that security.

Stock Options and Warrants

For the three months and nine months ended September 30, 2011, outstanding options to purchase 0.1 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, 2011 and the nine months ended September 30, 2010, CMS Energy’s 7.75 percent convertible subordinated debentures would have increased diluted earnings

per share had they been included in the calculation. Using the if-converted method, the debentures would have had the following impacts on the calculation of diluted EPS:


In Millions
	Nine Months Ended
September 30	2011		2010

Increase to numerator from assumed reduction in interest expense	$	1	$	1
Increase to denominator from assumed conversion of debentures into common shares		0.7		0.7

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. Presented in the following table are the cost or carrying amounts and fair values of CMS Energy’s and Consumers’ long-term financial instruments:

¹ Includes current portion of notes receivable of $16 million at September 30, 2011 and $11 million at December 31, 2010.

² Includes current portion of long-term debt of $1,116 million at September 30, 2011 and $726 million at December 31, 2010.

³ Includes current portion of long-term debt of $338 million at September 30, 2011 and $37 million at December 31, 2010.

Notes receivable consist of EnerBank’s fixed-rate installment loans. EnerBank estimates the fair value of these loans using a discounted cash flows technique that incorporates 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. CMS Energy includes the value of the conversion features in estimating the fair value of its convertible debt, and incorporates, as appropriate, information on the market prices of CMS Energy common stock.

The effects of third-party credit enhancements are excluded from the fair value measurements of long-term debt. At September 30, 2011 and December 31, 2010, CMS Energy’s long-term debt included $103 million principal amount that was supported by third-party credit enhancements. This entire 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. 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 has been designated as an accounting hedge, 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.

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. Since Consumers is subject to regulatory accounting, the resulting fair value gains and losses would be deferred as regulatory assets or liabilities and would not affect net income.

Consumers also uses FTRs to manage price risk related to electricity transmission congestion. An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges. FTRs are accounted for as derivatives. Under regulatory accounting, all changes in fair value associated with these instruments are deferred as regulatory assets or liabilities until the instruments are settled.

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, 2011, CMS ERM held the following derivative contracts:

	•		a forward contract for the physical sale of 574 GWh of electricity through 2015 on behalf of one of CMS Energy’s non-utility generating plants;

	•		forward contracts to purchase 4.4 bcf and sell 7.5 bcf of natural gas through 2012 in CMS ERM’s role as a marketer of natural gas for third-party producers; and

	•		an option to sell 151 GWh of electricity through 2011.

Presented in the following table are the fair values of CMS Energy’s and Consumers’ derivative instruments:

² Liabilities exclude the impact of offsetting cash margin deposits paid by CMS ERM to other parties, which was less than $1 million at September 30, 2011 and December 31, 2010. CMS Energy presents these liabilities net of these impacts on its consolidated balance sheets.

Presented in the following table is the effect on CMS Energy’s consolidated statements of income of its derivatives not designated as hedging instruments:

Fuel for electric generation		—			1		—			3
Purchased and interchange power		—			1		—			2

Total CMS Energy	$	(1	)	$	4	$	(1	)	$	10

Consumers’ losses on FTRs deferred as regulatory assets were $1 million for the three months ended September 30, 2011 and its gains on FTRs deferred as regulatory liabilities were $3 million for the three months ended September 30, 2010. Consumers’ gains on FTRs deferred as regulatory liabilities were

$2 million for the nine months ended September 30, 2011 and $4 million for the nine months ended September 30, 2010.

CMS Energy’s derivative liabilities subject to credit-risk-related contingent features were less than $1 million at September 30, 2011 and were $1 million at December 31, 2010.

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 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.

At September 30, 2011, if counterparties within this industry concentration all failed to meet their contractual obligations, the loss to CMS Energy on contracts accounted for as derivatives would be less than $1 million. 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: NOTES RECEIVABLE

EnerBank provides unsecured consumer installment loans for financing home improvements. These loans totaled $439 million, net of an allowance for loan losses of $5 million, at September 30, 2011, and $386 million, net of an allowance for loan losses of $5 million, at December 31, 2010. At September 30, 2011, $16 million of EnerBank’s loans were classified as current notes receivable and $423 million were classified as non-current notes receivable on CMS Energy’s consolidated balance sheets. At December 31, 2010, $11 million of EnerBank’s loans were classified as current notes receivable and $375 million were classified as non-current notes receivable on CMS Energy’s consolidated balance sheets.

The allowance for loan losses is a valuation allowance to reflect estimated credit losses. The allowance is increased by the provision for loan losses and decreased by loan charge-offs net of recoveries. Management estimates the allowance balance required by taking into consideration historical loan loss experience, the nature and volume of the portfolio, economic conditions, and other factors. Loan losses are charged against the allowance when the loss is confirmed, but no later than the point at which a loan becomes 120 days past due.

Presented in the following table are the changes in the allowance for loan losses:

¹ Regulatory adjustments are the differences between amounts included in rates and the periodic benefit cost calculated. These regulatory adjustments were offset by surcharge revenues, resulting in no impact to net income for the periods presented.

CMS Energy’s and Consumers’ expected long-term rate of return on Pension Plan assets is eight percent. For the twelve months ended September 30, 2011, the actual return on Pension Plan assets was 2.0 percent, and for the twelve months ended September 30, 2010, the actual return was 11.6 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.

Presented in the following table is a reconciliation of the statutory U.S. federal income tax rate to the effective income tax rate from continuing operations, excluding noncontrolling interests:


Nine Months Ended September 30	2011			2010

CMS Energy, Including Consumers
U.S. federal income tax rate		35.0	%		35.0	%
Increase (decrease) in income taxes from:
MCIT law change, net of federal expense		(5.9	)		—
State and local income taxes, net of federal benefit		3.4			4.0
Medicare Part D exempt income, net of law change		(0.9	)		(0.9	)
Income tax credit amortization		(0.6	)		(0.6	)
Other, net		0.1			0.9

Effective income tax rate		31.1	%		38.4	%

Consumers
U.S. federal income tax rate		35.0	%		35.0	%
Increase (decrease) in income taxes from:
State and local income taxes, net of federal benefit		3.1			3.5
Medicare Part D exempt income, net of law change		(0.8	)		(1.3	)
Plant basis differences		0.2			0.3
Income tax credit amortization		(0.5	)		(0.5	)
Other, net		(0.3	)		(0.2	)

Effective income tax rate		36.7	%		36.8	%

CMS Energy’s effective tax rate for the nine months ended September 30, 2011, was reduced due to a one-time non-cash reduction in tax expense resulting from a change in Michigan tax law. In May 2011, Michigan enacted the MCIT, effective January 1, 2012. The MCIT, a simplified six percent corporate income tax, will replace the MBT, which is a complex multi-part business tax. Both the MBT and the MCIT are income taxes for financial reporting purposes, for which deferred income tax assets and liabilities are recorded. CMS Energy and Consumers remeasured their Michigan deferred income tax assets and liabilities at June 30, 2011 to reflect this change in law. Unlike the MBT, the MCIT does not allow future tax deductions to offset the book-tax differences that existed upon enactment of the tax. Due primarily to the elimination of these future tax deductions, Consumers eliminated $134 million of net deferred tax assets associated with its utility book-tax temporary differences, recognizing a $134 million regulatory asset (not including the effects of income tax gross-ups), and in addition to the amounts related to Consumers, CMS Energy eliminated $32 million of net deferred tax liabilities associated with its non-utility book-tax temporary differences, recognizing a $32 million deferred income tax benefit.

For the nine months ended September 30, 2010, CMS Energy recognized deferred tax expense of $3 million to reflect the enactment of the Health Care Acts. The law change prospectively repealed the tax deduction for the portion of the health care costs reimbursed by the Medicare Part D subsidy for taxable years beginning after December 31, 2012.

12: REPORTABLE SEGMENTS
