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 IPP. Consumers’ electric utility operations include the generation, purchase, distribution, and sale of electricity, and Consumers’ gas utility operations include the purchase, transmission, storage, distribution, and sale of natural gas. Consumers’ customer base consists of a mix of residential, commercial, and diversified industrial customers. CMS Enterprises, through its subsidiaries and equity investments, owns 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.

During the past several years, CMS Energy’s “Growing Forward” business strategy has emphasized the following key elements:

Utility Investment

Consumers expects to make capital investments of more than $6 billion over the next five years, with a key aspect of its strategy being the balanced energy initiative. The balanced energy initiative is a comprehensive energy resource plan to meet Consumers’ projected short-term and long-term electric power requirements with energy efficiency, demand management, expanded use of renewable energy, development of new power plants, pursuit of additional PPAs to complement existing generating sources, potential retirement or mothballing of older generating units, and continued operation of others.

Renewable energy projects are a major component of Consumers’ planned capital investments. Consumers expects to spend $600 million on renewable energy investments through 2015. 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 February 2011, Consumers filed with the MPSC an amended renewable energy plan, reducing the surcharge billed to customers by an annual amount of $55 million. Consumers proposed the amendment as a result of lower-than-anticipated costs to comply with the renewable energy requirements prescribed by the 2008 Energy Law.

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, will increase the capacity of Ludington from its present level of 1,872 MW to about 2,172 MW. Consumers expects its share of the project cost to total $400 million.

Consumers’ smart grid program will also represent a significant capital investment. The initial substantial deployment, planned for 2012, will include advanced metering infrastructure and follow a phased approach. Consumers expects to spend $355 million on its smart grid program through 2015.

Regulation

Regulatory matters are a key aspect of CMS Energy’s and Consumers’ businesses, particularly Consumers’ rate cases and regulatory proceedings before the MPSC. Recent significant regulatory events and developments are summarized below.

	•		2010 Gas Rate Case: In August 2010, Consumers filed an application with the MPSC seeking an annual gas rate increase of $55 million based on an 11 percent authorized return on equity.

			In January 2011, Consumers filed support for a self-implemented annual gas rate increase of $48 million. In February 2011, Consumers revised the proposed self-implemented increase to $29 million. The MPSC issued an order in February 2011, delaying Consumers’ self-implementation in order to give other parties to the proceeding an opportunity to respond to Consumers’ revised self-implementation filing. In anticipation of a final order, all parties may file briefs supporting their positions. In April 2011, Consumers filed an initial brief supporting an annual gas rate increase of $45 million, and the MPSC Staff submitted a revised recommended annual revenue increase of $16 million. The parties have engaged in discussions in an effort to settle the issues in this case. As of April 28, 2011, a settlement was not yet finalized, but Consumers believes settlement is likely.

	•		Electric Revenue Decoupling Mechanism: In March 2011, Consumers filed its first reconciliation of the electric revenue decoupling mechanism, requesting recovery of $27 million from customers for the period December 2009 through November 2010. The decoupling mechanism was authorized in Consumers’ 2009 electric rate case order, subject to certain conditions, and extended in the 2010 electric rate case order. It allows Consumers to adjust future electric rates to compensate for changes in sales volumes resulting from weather fluctuations, energy efficiency,

and conservation. Various parties have filed appeals concerning the electric decoupling mechanism.

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 on a path to issue final new source performance standards in May 2012 addressing greenhouse gas emissions from fossil-fueled electric generating units. The EPA is also expected to propose guidelines for states to regulate greenhouse gas emissions from 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. CMS Energy and Consumers are monitoring these developments for potential effects on their operations.

Safety

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.

Financial Performance in 2011 and Beyond

For the three months ended March 31, 2011, CMS Energy’s net income available to common stockholders was $135 million, and diluted earnings per share were $0.52. This compares with net income available to common stockholders of $85 million and diluted earnings per share of $0.34 for the three months ended March 31, 2010. Among the most significant factors contributing to CMS Energy’s improved performance were benefits from electric and gas rate orders and increased gas deliveries, offset partially by higher distribution and service restoration costs.

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 have stabilized. Although Michigan’s economy continues to be affected by the recession and its impact on the state’s automotive industry, by high unemployment rates, and by a modestly shrinking population, there are indications that the recession has eased in Michigan. Consumers expects its electric sales to increase by about 1.5 percent annually through 2016, driven largely by the continued rise in industrial production. Consumers is projecting that its gas sales will decline by about one percent annually through 2016, due largely to energy efficiency and conservation.

As Consumers continues to seek 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 aggressive goals for 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.

¹		Non-cash transactions comprise depreciation and amortization, changes in deferred income taxes, postretirement benefits expense, and other non-cash items.

²		Other core working capital comprises other changes in accounts receivable and accrued revenues, inventories, and accounts payable.

For the three months ended March 31, 2011, net cash provided by operating activities at CMS Energy and at Consumers increased $184 million compared with 2010. The increase was due primarily to higher net income, the absence of Pension Plan contributions in 2011, and increased collection of accounts receivable.

Net cash provided by financing activities	$	3		$	71		$	(68	)

For the three months ended March 31, 2011, net cash used in financing activities at CMS Energy increased $282 million compared to 2010. The change was due primarily to a decrease in net proceeds from borrowings by CMS Energy.

For the three months ended March 31, 2011, net cash provided by financing activities at Consumers decreased $68 million compared with 2010. The change was due primarily to a decrease in stockholder’s contribution from CMS Energy, offset partially by a decrease in common stock dividend payments to CMS Energy.

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 is restricted by certain terms included in its articles of incorporation, as well as by FERC requirements. For the three months ended March 31, 2011, Consumers paid $104 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 also had the following secured revolving credit facilities available at March 31, 2011:

¹		On March 31, 2011, CMS Energy entered into a $550 million secured revolving credit facility with a consortium of banks. 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.

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 March 31, 2011, $250 million of accounts receivable were eligible for transfer under this program.

CMS Energy’s new $550 million revolving credit agreement specifies a maximum debt-to-EBITDA ratio, as defined therein. Consumers’ new $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 March 31, 2011, as presented in the following table:



			Ratio at
Revolving Credit Agreement	Description	Maximum Limit	March 31, 2011

CMS Energy’s $550 million revolving credit agreement	Debt to EBITDA	6.0 to 1.0	4.54 to 1.0
Consumers’ $500 million revolving credit agreement	Debt to Capital	0.65 to 1.0	0.50 to 1.0

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 2, 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 2, 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 May 2010, Consumers announced plans to defer the development of its proposed 830 MW coal-fueled plant at its Karn/Weadock generating complex. This decision reflects reduced customer demand for

electricity due to the recession, forecasted lower natural gas prices due to recent developments in shale gas recovery technology, and projected surplus generating capacity in the MISO market. Consumers has been monitoring customer demand, fuel and power prices, and other market conditions, and has not set a timetable for a future decision about the project; however, the likelihood that the plant will be constructed has diminished significantly. 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. The 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. 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 March 31, 2011, the combination of these sources represented 77 percent of Consumers’ 2015 REC requirement.

To meet its renewable capacity requirements, Consumers expects to add more than 500 MW of owned or contracted renewable capacity by 2015. Through March 2011, Consumers has contracted for the purchase of 296 MW of nameplate capacity from renewable energy suppliers, which represents 59 percent of the 2015 renewable capacity requirement.

Consumers has secured more than 80,000 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 a 100-MW wind park in Mason County, the Lake Winds Energy Park, which Consumers expects to be operational in late 2012. Various parties are opposing a special use permit or have proposed restrictive zoning conditions before the local planning commission in an effort to stop the Lake Winds project. Consumers will continue to seek 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 have stabilized, and expects weather-adjusted electric deliveries to increase in 2011 by 2.5 percent compared with 2010. Consumers’ outlook for 2011 includes continuing growth in deliveries to its largest customer, which produces energy-related and electronic device components. Excluding this customer’s growth, Consumers expects weather-adjusted electric deliveries in 2011 to increase by 1.5 percent compared with 2010.

Consumers expects average electric delivery growth of about 1.5 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 and expansion or contraction of manufacturing facilities, population trends, and housing activity.

A decoupling mechanism was authorized by the MPSC in Consumers’ 2009 electric rate case order, subject to certain conditions, and extended in the 2010 electric rate case order. It allows Consumers to adjust future electric rates to compensate for changes in sales volumes resulting from weather

fluctuations, energy efficiency, and conservation. This mechanism reduces the volatility of 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 March 31, 2011, electric deliveries under the ROA program were at the ten percent limit and alternative electric suppliers were providing 801 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 June 2010, FERC issued a Notice of Proposed Rulemaking to establish a closer link between regional electric transmission planning and cost allocations to ensure the construction of required transmission facilities. In a related matter, 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 protest and request for rehearing with FERC, opposing the allocation methodology in the MISO tariff revision. 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. For details on Consumers’ electric rate case, PSCR, electric revenue decoupling, uncollectible expense tracking mechanism, electric operation and maintenance expenditures show-cause order, Big Rock decommissioning, renewable energy plan, energy optimization plan, and electric depreciation, see Note 3, Regulatory Matters, “Consumers’ Electric Utility.”

Electric Environmental Estimates: Consumers’ operations are subject to various state and federal environmental laws and regulations. Consumers continues to focus on complying with the Clean Air Act, Clean Water Act, and numerous state and federal environmental regulations, and estimates that it will incur expenditures of $1.9 billion from 2011 through 2018 to comply with these regulations. Consumers expects to recover these costs in customer rates, but cannot guarantee this result. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters:

Clean Air Interstate Rule/Clean Air Transport Rule/Federal Hazardous Air Pollutant Regulation: Due to a December 2008 court decision that remanded CAIR back to the EPA, CAIR remains in effect, pending the EPA’s finalization of a new rule. In July 2010, the EPA released CATR, a proposed rule that would replace CAIR.

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 electric generating units would require additional controls for hazardous air pollutants. Existing sources must meet the standards generally within three years of issuance of the final rule. The final rule is expected to be issued in November 2011.

Presently, Consumers’ strategy to comply with CATR and the MACT standards involves the installation of state-of-the-art emission control equipment; however, Consumers continues to evaluate these proposed rules in conjunction with other EPA rulemakings. If adopted in their present form, these rules could result in additional or accelerated environmental compliance costs related to Consumers’ fossil-fueled power plants and the retirement or mothballing of some or all of Consumers’ older, smaller generating units.

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 2009, the U.S. Court of Appeals for the Second Circuit issued a decision that allowed states and private plaintiffs to bring lawsuits in the federal courts against utilities and others based on common law nuisance theories that challenged the defendants’ greenhouse gas emissions. This decision potentially allowed federal judges to impose caps on such emissions on a case-by-case basis without reference to any legislatively created standards. A group of utilities filed a petition with the U.S. Supreme Court, seeking review of the U.S. Court of Appeals decision. In December 2010, the U.S. Supreme Court granted the petition and will decide the case on its merits. Consumers will continue to monitor this litigation.

In 2010, the EPA released its Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule. The final rule, which numerous parties have challenged in the U.S. Court of Appeals for the D.C. Circuit, sets limits for greenhouse gas emissions that define when permits are required for new and existing industrial facilities under NSR PSD and Title V Operating Permit programs. The EPA issued revised guidance on this rule in March 2011. Consumers does not expect that the rule will require it to incur significant expenditures for efficiency upgrades for modified or new facilities.

In December 2010, the EPA entered into a settlement agreement with certain states and environmental groups that puts it on a path to issue proposed new source performance standards in July 2011. This proposal will address greenhouse gas emissions for new fossil-fueled electric generating units and major modifications under Section 111(b) of the Clean Air Act. The EPA will promulgate final standards by May 2012. On the same schedule, the EPA is expected to propose emissions guidelines for the states to regulate greenhouse gas emissions from existing sources 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 this settlement and any proposed new source performance standards regulations.

In March 2011, the EPA issued a final rule that extends to September 30, 2011 the deadline for reporting 2010 greenhouse gas emissions data under the Greenhouse Gas Reporting Program. The original deadline was March 31, 2011. Consumers is prepared to comply with the final rule.

Litigation, as well as federal laws, EPA regulations regarding greenhouse gases, or similar treaties, state laws, or rules, if enacted, could require Consumers to replace equipment, install additional equipment for emission controls, purchase emission allowances, curtail operations, arrange for alternative sources of supply, or take other steps to manage or lower the emission of greenhouse gases. Although associated capital or operating costs relating to greenhouse gas regulation or legislation could be material and cost recovery cannot be assured, Consumers expects to recover these costs and capital expenditures in rates consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.

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

Water: In March 2011, the EPA issued a proposed rule to regulate existing electric generating plant cooling water intake systems. Consumers is evaluating this proposed rule and its potential impacts on Consumers’ plants.

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

Other electric environmental matters could have a major impact on Consumers’ outlook. For additional details on other electric environmental matters, see Note 2, 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 have stabilized, and expects weather-adjusted gas deliveries to increase in 2011 by one percent compared with 2010. Over the next five years, Consumers expects average gas deliveries to decline about one percent annually, reflecting the predicted effects of energy efficiency programs and continued conservation. Actual delivery levels from year to year may vary from this trend due to:

•

fluctuations in weather;

•

use by IPPs;

•

availability and development of renewable energy sources;

•

changes in gas prices;

•

Michigan economic conditions, including population trends and housing activity;

•

the price of competing energy sources or fuels; and

•

energy efficiency and conservation.

A decoupling mechanism was authorized by the MPSC in Consumers’ 2009 gas rate case order, subject to certain conditions. It allows Consumers to adjust future gas rates to compensate for changes in sales volumes by class arising 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 its gas revenue.

Gas Rate Matters: Rate matters are critical to Consumers’ gas utility business. For details on Consumers’ gas rate case and GCR, see Note 3, Regulatory Matters, “Consumers’ Gas Utility.”

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

•

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

•

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

•

certain disclosures to homeowners and regulatory agencies.

Consumers continues to comply with laws and regulations governing natural gas pipeline safety. If these proposed laws are put into effect, Consumers could incur significant additional costs related to its natural gas pipeline safety programs. Consumers expects that it would be able to recover 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 2, Contingencies and Commitments, “Consumers’ Gas Utility Contingencies — Gas Environmental Matters.”

Consumers’ Other Outlook and Uncertainties

Smart Grid: Consumers’ grid modernization effort continues to move forward. The foundation of this effort is the installation of advanced metering and the infrastructure to support it. The installation will include smart meters that are capable of transmitting and receiving data, a two-way communications network, and modifications to Consumers’ existing information technology systems to manage the data and enable changes to key business processes. Consumers expects to experience operational benefits upon the installation of smart meters. Smart meters are also intended to allow customers to monitor and manage their energy usage and help reduce demand during critical peak times, resulting in lower peak capacity requirements. Due to this system’s complexity and the relative immaturity of the technology, Consumers intends to continue its phased implementation approach. In 2012, Consumers plans to begin a larger-scale deployment to expand testing of the operations and systems of the selected advanced metering infrastructure network communications vendor.

Enterprises Outlook and Uncertainties

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

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

•

indemnity and environmental remediation obligations at Bay Harbor;

•

the outcome of certain legal proceedings;

•

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

•

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

•

changes in commodity prices and interest rates on certain derivative contracts that do not qualify for hedge accounting and must be marked to market through earnings;

•

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

•

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

For additional details regarding the enterprises segment’s uncertainties, see Note 2, Contingencies and Commitments.

Other Outlook and Uncertainties

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 2, Contingencies and Commitments and Note 3, Regulatory Matters.

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 March 31, 2011, and two percent of CMS Energy’s Net Income Available to Common Stockholders for the three months ended March 31, 2011. The carrying value of EnerBank’s loan portfolio was $380 million at March 31, 2011. Its loan portfolio was funded primarily by deposit liabilities of $377 million. Twelve-month rolling average default rates on loans held by EnerBank have declined from 1.4 percent at December 31, 2010 to 1.3 percent at March 31, 2011. EnerBank expects the rate of loan defaults to decline further, and to level out at about 1.0 percent. CMS Energy is required to ensure that EnerBank remains well capitalized.

NEW ACCOUNTING STANDARDS

There were no implementations of new accounting standards that had a material impact on CMS Energy’s or Consumers’ consolidated financial statements. Also, there are no new accounting standards issued but not yet effective that are expected to have a material impact on CMS Energy’s or Consumers’ consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

These interim Consolidated Financial Statements have been prepared by CMS Energy and Consumers in accordance with accounting principles generally accepted in the U.S. for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. As a result, CMS Energy and Consumers have condensed or omitted certain information and Note disclosures normally included in consolidated financial statements prepared in accordance with accounting principles generally accepted in the U.S. CMS Energy and Consumers have reclassified certain prior period amounts to conform to the presentation in the current period. In management’s opinion, the unaudited information contained in this report reflects all adjustments of a normal recurring nature necessary to ensure the fair presentation of financial position, results of operations, and cash flows for the periods presented. The Notes to Consolidated Financial Statements and the related Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related Notes contained in the 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: 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.

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

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

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

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

The SERP state and municipal bonds are investment grade securities that are valued using a matrix pricing model that incorporates Level 2 market-based information. The fair value of the bonds is derived from various observable inputs, including benchmark yields, reported trades, broker/dealer quotes, bond ratings, and general information on market movements normally considered by market participants when pricing such debt securities. CMS Energy and Consumers report their SERP assets in Other non-current assets on their Consolidated Balance Sheets. For additional details about SERP securities, see Note 6, Financial Instruments.

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

Derivative Instruments: CMS Energy and Consumers value their derivative instruments using either a market approach that incorporates information from market transactions, or an income approach that discounts future expected cash flows to a present value amount. They use various inputs to value the derivatives depending on the type of contract and the availability of market data. CMS Energy has exchange-traded derivative contracts that are valued based on Level 1 quoted prices in actively traded markets, as well as derivatives that are valued using Level 2 inputs, including commodity market prices, interest rates, credit ratings, default rates, and market-based seasonality factors. CMS Energy 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 derivative classified as Level 3 is an electricity sales agreement held by CMS ERM. At December 31, 2010 and in prior periods, quoted electricity prices were not available for the entire term of the agreement, and a proprietary forward pricing model was used to determine fair value. At March 31, 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.

For all fair values other than Level 1 prices, CMS Energy and Consumers incorporate adjustments for the risk of nonperformance. For derivative assets, a credit adjustment is applied against the asset based on the published default rate for the credit rating that CMS Energy and Consumers assign to the counterparty based on an internal credit-scoring model. This model considers various inputs, including the counterparty’s financial statements, credit reports, trade press, and other information that would be available to market participants. To the extent that the internal ratings are comparable to credit ratings published by independent rating agencies, the resulting credit adjustment is classified within Level 2. If the internal model results in a rating that is outside of the range of ratings given by the independent agencies and the credit adjustment is significant to the overall valuation, the derivative fair value is classified as Level 3. CMS Energy and Consumers adjust their derivative liabilities downward to reflect the risk of their own nonperformance, based on their published credit ratings. 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 7, Derivative Instruments.

2: CONTINGENCIES AND COMMITMENTS

CMS Energy Contingencies

Gas Index Price Reporting Investigation: In 2002, CMS Energy notified appropriate regulatory and governmental agencies that some employees at CMS MST and CMS Field Services appeared to have provided inaccurate information regarding natural gas trades to various energy industry publications, which compile and report index prices. CMS Energy cooperated with an investigation by the DOJ regarding this matter. Although CMS Energy has not received any formal notification that the DOJ has completed its investigation, the DOJ’s last request for information occurred in 2003, and CMS Energy completed its response to this request in 2004. CMS Energy is unable to predict the outcome of the DOJ investigation and what effect, if any, the investigation will have on CMS Energy.

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

•

In 2005, CMS MST was served with a summons and complaint that named CMS Energy, CMS MST, and CMS Field Services as defendants in a putative class action filed in Kansas state court, Learjet, Inc., et al. v. Oneok, Inc., et al. The complaint alleges that during the putative class period, January 1, 2000 through October 31, 2002, the defendants engaged in a scheme to violate the Kansas Restraint of Trade Act. The plaintiffs, who allege they purchased natural gas from the defendants and others for their facilities, are seeking statutory full consideration damages consisting of the full consideration paid by plaintiffs for natural gas.

•

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

•

Breckenridge Brewery of Colorado, LLC and BBD Acquisition Co. v. Oneok, Inc., et al., a class action complaint brought on behalf of retail direct purchasers of natural gas in Colorado, was filed in Colorado state court in May 2006. Defendants, including CMS Energy, CMS Field Services, and CMS MST, are alleged to have violated the Colorado Antitrust Act of 1992 in connection with their natural gas price reporting activities. Plaintiffs are seeking full refund damages.

•

A class action complaint, Arandell Corp., et al. v. XCEL Energy Inc., et al., was filed in 2006 in Wisconsin state court on behalf of Wisconsin commercial entities that purchased natural gas between January 1, 2000 and October 31, 2002. The defendants, including CMS Energy, CMS ERM, and Cantera Gas Company, are alleged to have violated Wisconsin’s antitrust statute. The plaintiffs are seeking full consideration damages, plus exemplary damages and attorneys’ fees. After dismissal on jurisdictional grounds in 2009, plaintiffs filed a new case in the U.S. District Court for the Eastern District of Michigan. In November 2010, the MDL judge issued an opinion and order granting the CMS Energy defendants’ motion to dismiss the new Michigan case on statute-of-limitations grounds and all CMS Energy defendants have been dismissed from the Arandell Michigan case.

•

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

•

In 2005, J.P. Morgan Trust Company, in its capacity as Trustee of the FLI Liquidating Trust, filed an action in Kansas state court against a number of energy companies, including CMS Energy, CMS MST, and CMS Field Services. The complaint alleges various claims under the Kansas Restraint of Trade Act. The plaintiff is seeking statutory full consideration damages for its purchases of natural gas between January 1, 2000 and December 31, 2001. This case is not a class action.

After removal to federal court, the Learjet, Heartland, Breckenridge, both Arandell cases, Newpage, and J.P. Morgan cases were transferred to the MDL case. CMS Energy was dismissed from the Learjet, Heartland, and J.P. Morgan cases in 2009, but other CMS Energy defendants remain parties. All

CMS Energy defendants were dismissed from the Breckenridge case in 2009. It is expected that the plaintiffs in this case will appeal this decision after all claims against defendants have been dismissed. At this time, there is no pending appeal. In June 2010, CMS Energy and Cantera Gas Company were dismissed from the Newpage case; the Arandell (Wisconsin) case was reinstated against CMS ERM; and the Arandell (Wisconsin) case was consolidated with the Newpage case. These two consolidated cases remain pending only against CMS ERM. Pending before the court in all of the MDL cases are the defendants’ renewed motions for summary judgment based on FERC preemption. In all but the J.P. Morgan case, there are also pending plaintiffs’ motions for class certification. These motions are not yet decided. In October 2010, the MDL court entered an order denying the plaintiffs’ motion for leave to amend their complaint to add a federal Sherman Antitrust Act claim.

These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions. Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s possible loss would be based on widely varying models previously untested in this context. Defenses are being pursued vigorously, which could result in the dismissal of the cases completely, but CMS Energy is unable to predict the outcome of these matters. If the outcome is unfavorable, these cases could have a material adverse impact on CMS Energy’s 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 December 2010, CMS Energy submitted a revised scope of remedies to the EPA for approval and is awaiting a response from the EPA regarding its submission. Also 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. 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 believes that this is not a valid claim and intends to dispute it.

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 $223 million, which includes accretion expense. At March 31, 2011, CMS Energy had a recorded liability of $94 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 $115 million. CMS Energy expects to pay $23 million during the remainder of 2011, $16 million in 2012, $7 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 sale of CMS Energy’s oil, gas, and methanol projects in Equatorial Guinea and the claim of the government of Equatorial Guinea that CMS Energy owes $142 million in taxes in connection with that sale. CMS Energy concluded that the government’s tax claim is without merit and the purchaser of CMS Oil and Gas submitted a response to the government rejecting the claim. The government of Equatorial Guinea indicated in 2008 that it still intends to pursue its claim. CMS Energy cannot predict the financial impact or outcome of this matter.

Consumers’ Electric Utility Contingencies

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

Cleanup and Solid Waste: Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. At March 31, 2011, Consumers had a recorded liability of $1 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. 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. 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 March 31, 2011, Consumers had a recorded liability of $2 million, the minimum amount in the range of its estimated probable Superfund liability.

The timing of payments related to Consumers’ remediation and other response activities at its Superfund and NREPA sites is uncertain. Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, different remediation techniques, nature and extent of contamination, and legal and regulatory requirements, could affect its estimates of NREPA and Superfund liability.

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

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

Consumers is engaged in discussions with the EPA on all of these matters. Depending upon the outcome of these discussions, the EPA could bring legal action against Consumers and/or Consumers could be required to install additional pollution control equipment at some or all of its coal-fueled electric generating plants, surrender emission allowances, engage in Supplemental Environmental 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.

DOE Litigation: In 1997, a U.S. Court of Appeals decision confirmed that the DOE was to begin accepting deliveries of spent nuclear fuel for disposal by January 1998. Subsequent U.S. Court of Appeals litigation, in which Consumers and other utilities participated, has not been successful in producing more specific relief for the DOE’s failure to accept the spent nuclear fuel.

A number of court decisions support the right of utilities to pursue damage claims in the U.S. Court of Claims against the DOE for failure to take delivery of spent nuclear fuel. Consumers filed a complaint in 2002. If Consumers’ litigation against the DOE is successful, Consumers plans to use any recoveries as reimbursement for the incurred costs of spent nuclear fuel storage during Consumers’ ownership of Palisades and Big Rock. The sale of Palisades and the Big Rock ISFSI did not transfer the right to any recoveries from the DOE related to costs of spent nuclear fuel storage incurred during Consumers’ ownership of Palisades and Big Rock. Consumers is involved in ongoing discussions with the DOE to settle this lawsuit.

Nuclear Fuel Disposal Cost: Consumers has a recorded liability of $163 million to fund the disposal of spent nuclear fuel used before 1983. This balance comprises the principal amount of $44 million collected from customers for spent nuclear fuel disposal fees and $119 million of interest accrued on those collections. The liability, which is classified in Long-term debt on CMS Energy’s and Consumers’ Consolidated Balance Sheets, is payable to the DOE when it begins to accept delivery of spent nuclear fuel. In conjunction with the sale of Palisades and the Big Rock ISFSI in 2007, Consumers retained this obligation and provided a letter of credit to Entergy as security for this obligation. Consumers is involved in ongoing discussions with the DOE to settle this liability in conjunction with the settlement of Consumers’ lawsuit with the DOE. In its November 2010 electric rate order, the MPSC directed Consumers to establish, within six months of the date of the order, an independent trust fund for the amount payable to the DOE. In December 2010, Consumers filed a Petition for Rehearing and Clarification, requesting that the MPSC modify its conclusion that this amount be placed in a trust. In response to Consumers’ Petition for Rehearing and Clarification, the MPSC issued an order in March 2011 indicating it did not intend to prejudge the terms of any potential settlement agreement between Consumers and the DOE. The MPSC granted Consumers ninety days to finalize a settlement with the DOE. If a settlement agreement is reached, Consumers will be required to file the agreement with the MPSC to address how the settlement proceeds will be distributed and to allow interested parties to comment on the reasonableness and prudence of the agreement. If Consumers enters into a settlement, Consumers will be permitted to petition the MPSC to relieve it of the obligation to fund all or any part of the trust. If Consumers does not enter into a settlement, it will be required to establish the independent trust fund required by the November 2010 electric rate order.

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 March 31, 2011, Consumers estimated its undiscounted remaining remediation and other response activity costs to be between $31 million and $45 million. Generally, Consumers has been able to recover most of its costs to date through proceeds from insurance settlements and customer rates.

At March 31, 2011, Consumers had a recorded liability of $31 million and a regulatory asset of $56 million that included $25 million of deferred MGP expenditures. The timing of payments related to the remediation and other response activity at Consumers’ former MGP sites is uncertain. Consumers expects its remediation and other response activity costs to average $6 million annually over the next five years. Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, changes in remediation techniques, or legal and regulatory requirements, could affect Consumers’ estimates of annual response activity costs and the MGP liability.

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 March 31, 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.

At March 31, 2011, the maximum obligation and carrying amounts for Consumers’ guarantees were less than $1 million.

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



		Events That Would Require
Guarantee Description	How Guarantee Arose	Performance

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

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

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

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

Other Contingencies

In addition to the matters disclosed in this Note and Note 3, 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.

3: 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 Case: 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 February 2011, Consumers filed an application to reconcile the total revenues collected under its self-implemented rates with those that would have been collected under the rates authorized by the MPSC. This reconciliation found that no refund to customers is required.

In its July 2010 order allowing Consumers to self-implement its rate increase, the MPSC expressed concern about utilities repeatedly self-implementing rate increases over short time periods, and before the return of previous overcollections of self-implemented rate increases. In August 2010, the Attorney General filed a claim for appeal with the Michigan Court of Appeals regarding the MPSC’s July 2010 order.

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.

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

$1.7 billion


¹		In this reconciliation, intervenors are seeking disallowances ranging from $11 million to $42 million. In March 2011, the administrative law judge recommended that the MPSC allow Consumers to include its 2009 net underrecovery in the 2011 PSCR plan year, with the exception of $2 million of net replacement power costs associated with an outage at Consumers’ Whiting Plant.

Electric Revenue 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 decoupling mechanism was authorized by the MPSC in Consumers’ 2009 electric rate case order, subject to certain conditions, and extended in the 2010 electric rate case order. It allows Consumers to adjust future electric rates to compensate for changes in sales volumes resulting from weather fluctuations, energy efficiency, and conservation. Various parties have filed appeals concerning the electric decoupling mechanism. At March 31, 2011, Consumers had a $48 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 November 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 November 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 December 2005, the MPSC authorized Consumers to increase its electric rates. In the same order, the MPSC ordered Consumers to spend certain amounts on future tree-trimming and line-clearing activities, as well as on the operation and maintenance of Consumers’ fossil-fueled power plants. At that time, the MPSC also ordered Consumers to establish mechanisms to track these expenditures and stated that the rate increase was subject to refund with interest if the specified amounts were not spent on these activities.

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

Consumers’ response indicated that the total amount it spent on forestry and fossil-fueled plant operation and maintenance activity for the years 2006 through 2009 exceeded the total amounts included in rates for these activities.

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

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, and incurred $55 million for nuclear fuel storage costs as a result of the DOE’s failure to accept spent nuclear fuel. Consumers is seeking recovery of these costs from the DOE. At March 31, 2011, Consumers had an $85 million regulatory asset recorded on its Consolidated Balance Sheets for these costs.

Renewable Energy Plan: In June 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 February 2011, Consumers filed an amended renewable energy plan, reducing the surcharge billed to customers by an annual amount of $55 million. Consumers proposed the amendment as a result of lower-than-anticipated costs to comply with the renewable energy requirements prescribed by the 2008 Energy Law.

Energy Optimization Plan: In April 2010, Consumers filed with the MPSC its first annual report and reconciliation for its energy optimization plan, requesting approval of Consumers’ reconciliation of energy optimization plan costs for 2009. Consumers also requested approval 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. In March 2011, the administrative law judge recommended that the MPSC approve Consumers’ reconciliation as filed, with minor exceptions.

For exceeding its 2010 electric and gas savings targets, Consumers will request the MPSC’s approval to collect $8 million, the maximum incentive, in the energy optimization reconciliation to be filed in April 2011.

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

Also in February 2010, Consumers filed an electric depreciation case for Ludington, the pumped-storage plant jointly owned by Consumers and Detroit Edison. This case, filed jointly with Detroit Edison, requests an increase in annual depreciation expense. Consumers’ share of this increase is $9 million annually.

Consumers’ Gas Utility

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

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 2011, Consumers filed a letter with the MPSC revising the proposed self-implemented increase to $29 million. The MPSC issued an order in February 2011 delaying Consumers’ self-implementation in order to give other parties to the proceeding an opportunity to respond to Consumers’ revised self-implementation filing.

Parties have filed briefs supporting their positions. In April 2011, Consumers filed an initial brief supporting an annual gas rate increase of $45 million. Also in April 2011, the MPSC Staff submitted a revised proposed annual revenue increase of $16 million. The parties have engaged in discussions in an effort to settle the issues in this case. As of April 28, 2011, a settlement was not yet finalized, but Consumers believes settlement is likely.

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.

¹		On March 31, 2011, CMS Energy entered into a $550 million secured revolving credit facility with a consortium of banks. 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.

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 March 31, 2011, $250 million of accounts receivable were eligible for transfer, and no accounts receivable had been transferred under the program. During the three months ended March 31, 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 March 31, 2011:


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

Dividend Restrictions: Under provisions of CMS Energy’s senior notes indenture, at March 31, 2011, payment of common stock dividends by CMS Energy was limited to $1.0 billion.

Under the provisions of its articles of incorporation, at March 31, 2011, Consumers had $453 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 three months ended March 31, 2011, CMS Energy received $104 million of common stock dividends from Consumers.

5: EARNINGS PER SHARE — CMS ENERGY

Presented in the following table are CMS Energy’s basic and diluted EPS computations based on Income from Continuing Operations:


	In Millions, Except Per Share Amounts
Three Months Ended March 31	2011		2010

Income Available to Common Stockholders
Income from Continuing Operations	$	133	$	89
Less Preferred Stock Dividends		—		3

Average Common Shares Outstanding
Weighted average shares — basic		250.0		228.0

Weighted average shares — diluted		261.7		246.5
Income from Continuing Operations per Average Common Share Available to Common Stockholders
Basic	$	0.53	$	0.38
Diluted	$	0.51	$	0.35

Contingently Convertible Securities

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

Stock Options and Warrants

For the three months ended March 31, 2011, outstanding options to purchase 0.3 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 three months ended March 31, 2010, there was no impact on diluted EPS from CMS Energy’s 7.75 percent convertible subordinated debentures. Using the if-converted method, the debentures would have:

	•		increased the numerator of diluted EPS by less than $1 million for the three months ended March 31, 2010, from an assumed reduction of interest expense, net of tax; and

	•		increased the denominator of diluted EPS by 0.7 million shares for the three months ended March 31, 2010.

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

6: 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:


							In Millions

Long-term debt ³		4,516		4,895		4,525		4,891


¹		Includes current portion of notes receivable of $13 million at March 31, 2011 and $11 million at December 31, 2010.

²		Includes current portion of long-term debt of $1,251 million at March 31, 2011 and $726 million at December 31, 2010.

³		Includes current portion of long-term debt of $337 million at March 31, 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’s common stock.

The effects of third-party credit enhancements are excluded from the fair value measurements of long-term debt. At March 31, 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.

The mutual fund classified as available for sale is a short-term, fixed-income fund. During the three months ended March 31, 2011, CMS Energy contributed $27 million to the SERP, which included a contribution of $20 million by Consumers. The contributions were used to acquire additional shares in the mutual fund. State and municipal bonds classified as available for sale consist of investment grade state and municipal bonds. Debt securities classified as held to maturity consist primarily of mortgage-backed securities held by EnerBank, as well as state and municipal bonds held by EnerBank.

During each of the three-month periods ended March 31, 2011 and 2010, the proceeds from CMS Energy’s sales of investment securities were $1 million, which included proceeds from Consumers’ sales of investment securities of less than $1 million. All of the proceeds were related to sales of state and municipal bonds that were held within the SERP and classified as available for sale. Gross realized losses on these sales were less than $1 million for CMS Energy and Consumers during each period.

7: DERIVATIVE INSTRUMENTS

In order to limit exposure to certain market risks, primarily changes in commodity prices, interest rates, and foreign exchange rates, CMS Energy and Consumers may enter into various risk management contracts, such as forward contracts, futures, options, and swaps. In entering into these contracts, they follow established policies and procedures under the direction of an executive oversight committee

consisting of senior management representatives and a risk committee consisting of business unit managers. Neither CMS Energy nor Consumers enters into any derivatives for trading purposes.

The contracts used to manage market risks may qualify as derivative instruments. If a contract is a derivative and does not qualify for the normal purchases and sales exception, the contract is recorded on the balance sheet at its fair value. Each reporting period, the resulting asset or liability is adjusted to reflect any change in the fair value of the contract. Since none of CMS Energy’s or Consumers’ derivatives 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 1, Fair Value Measurements.

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

	•		they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or bcf of natural gas);

	•		they qualify for the normal purchases and sales exception; or

	•		there is not an active market for the commodity.

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

CMS ERM has not designated its contracts to purchase and sell electricity and natural gas as normal purchases and sales and, therefore, CMS Energy accounts for those contracts as derivatives. To manage commodity price risks associated with these forward purchase and sale contracts, CMS ERM uses various financial instruments, such as futures, options, and swaps. At March 31, 2011, CMS ERM held the following derivative contracts:

	•		a forward contract for the physical sale of 642 GWh of electricity through 2015 on behalf of one of CMS Energy’s non-utility generating plants;

	•		futures contracts through 2011 as an economic hedge of 24 percent of the generating plant’s natural gas requirements needed to serve a steam sales contract, for a total of 0.2 bcf of natural gas;

	•		forward contracts to purchase 3.1 bcf and sell 6.7 bcf of natural gas through 2011 in CMS ERM’s role as a marketer of natural gas for third-party producers; and

	•		an option to sell 458 GWh of electricity, and as an economic hedge, contracts to purchase 0.6 bcf of natural gas 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 March 31, 2011 and December 31, 2010. CMS Energy presents these liabilities net of these impacts on its Consolidated Balance Sheets.

CMS Energy’s derivative liabilities subject to credit-risk-related contingent features were $1 million at March 31, 2011 and 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 Energy reduces this risk through established policies and procedures. CMS Energy assesses credit quality by considering credit ratings, financial condition, and other available information for counterparties. A credit limit is established for each counterparty based on the evaluation of its credit quality. Exposure to potential loss under each contract is monitored and action is taken when appropriate.

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

At March 31, 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.

8: NOTES RECEIVABLE

EnerBank provides unsecured consumer installment loans for financing home improvements. These loans totaled $380 million, net of an allowance for loan losses of $5 million, at March 31, 2011, and $385 million, net of an allowance for loan losses of $5 million, at December 31, 2010. At March 31, 2011, $13 million of EnerBank’s loans were classified as current Notes receivable and $367 million were classified as non-current Notes receivable on CMS Energy’s Consolidated Balance Sheets. At December 31, 2010, $10 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. Loans 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:

For the twelve months ended March 31, 2011, the actual return on Pension Plan assets was 13.1 percent, and for the twelve months ended March 31, 2010 the actual return was 31.6 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.

10: INCOME TAXES

Presented in the following table is the difference between the effective income tax rate from continuing operations, excluding noncontrolling interests, and the statutory U.S. federal income tax rate:
