CMS Energy Corporation

Consumers Energy Company

MANAGEMENT’S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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

EXECUTIVE OVERVIEW

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

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

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

·regulation and regulatory matters;

·economic conditions;

·weather;

·energy commodity prices;

·interest rates; and

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

CMS Energy’s business strategy emphasizes the key elements depicted below:

11

Accountability is part of CMS Energy’s corporate culture.  CMS Energy is committed to making the right choices to serve its customers safely and affordably and to acting responsibly as a corporate citizen.  CMS Energy holds itself accountable to the highest standards of safety, operational performance, and ethical behavior, and works diligently to comply with all laws, rules, and regulations that govern the electric and gas industry.

In October 2013, Consumers Energy released its first-ever accountability report.  The report provides an overview of Consumers’ efforts to continue meeting Michigan’s energy needs safely and efficiently, and highlights Consumers’ commitment to Michigan businesses, its corporate citizenship, and its role in reducing the state’s air emissions.

SAFE, EXCELLENT OPERATIONS

The safety of employees, customers, and the general public remains a priority of CMS Energy and Consumers.  Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture.  These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions.  From 2006 to 2012, Consumers achieved a 76 percent reduction in the annual number of recordable safety incidents.

CUSTOMER VALUE

Consumers is undertaking a number of initiatives that reflect its intensified customer focus.  Consumers’ planned investments in reliability are aimed at improving safety, reducing customer outage frequency, reducing repetitive outages, and increasing customer satisfaction.  Also, in order to minimize increases in customer rates, Consumers has undertaken several initiatives to reduce costs through a voluntary separation plan in 2012, accelerated pension funding, employee and retiree health-care cost sharing, negotiated labor agreements, information system efficiencies, and productivity improvement programs.  Consumers has also filed certain applications with the MPSC that, if approved, are expected to result in cost savings for customers.  These initiatives, together with Consumers’ plans to accelerate further cost reductions, should allow Consumers to avoid increasing electric and gas base rates through 2014.  Consumers may reconsider this expectation should its assumptions change regarding the economy or other matters.

UTILITY INVESTMENT

Consumers expects to make capital investments of about $7 billion from 2013 through 2017.  Consumers has limited its capital investment program to those investments it believes are needed to provide safe, reliable, and efficient service to its customers.  Consumers’ capital investment program is expected to result in annual rate base growth of five to seven percent while allowing Consumers to maintain sustainable customer base rate increases (excluding PSCR and GCR charges) at or below the rate of inflation.

Among the key components of Consumers’ investment program are projects that will enhance customer value.  Consumers’ planned base capital investments of $3.5 billion comprise $2.1 billion of electric utility projects to improve reliability and increase capacity and $1.4 billion of gas utility projects to increase capacity and deliverability and enhance pipeline integrity.  An additional $1.4 billion of planned reliability investments at Consumers are aimed at reducing outages and improving customer satisfaction; these investments comprise $0.6 billion at the electric utility to strengthen circuits and substations, replace poles, and upgrade the Ludington pumped-storage plant, and $0.8 billion at the gas utility to replace mains and enhance transmission and storage systems.  Consumers also expects to spend $1.0 billion on environmental investments needed to comply with state and federal laws and regulations.

12

In December 2012, Consumers announced plans to build a 700-MW gas-fueled electric generating plant at its Thetford complex in Genesee County, Michigan.  In July 2013, Consumers received an air permit for the proposed plant from the MDEQ and, as allowed under the 2008 Energy Law, filed for approval of a certificate of necessity with the MPSC.  Construction of the plant, at an estimated cost of $750 million, is contingent upon obtaining the certificate of necessity and environmental permits.  Consumers expects that the plant would be operational in 2017.

While Consumers continues to move ahead with its plans to build a new gas-fueled electric generating plant, it also issued a solicitation in September 2013 seeking offers from owners of existing gas-fueled electric generating plants located in Michigan’s Lower Peninsula to sell their plants to Consumers.  The purchase by Consumers of one or more existing plants could represent a cost-effective alternative to building a new plant.

Renewable energy projects are another major component of Consumers’ planned capital investments.  Consumers expects to spend $0.3 billion on renewable energy investments, under an MPSC-approved renewable energy plan, from 2013 through 2017.  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 eight percent of its present power supply coming from such renewable sources as hydropower, landfill gas, biomass, wind, anaerobic digestion, and solar.

Consumers’ Smart Energy program, with an estimated total project capital cost of $0.8 billion, also represents a major capital investment.  The full-scale deployment of advanced metering infrastructure began in August 2012 and is planned to continue through 2019.  Consumers has spent $0.2 billion through 2012 on its Smart Energy program, and expects to spend an additional $0.3 billion, following a phased approach, from 2013 through 2017.

REGULATION

Regulatory matters are a key aspect of CMS Energy’s and Consumers’ businesses, particularly Consumers’ rate cases and regulatory proceedings before the MPSC.  In July 2013, Michigan Governor Rick Snyder appointed Sally Talberg to serve on the three-member MPSC for a six-year term, replacing Orjiakor Isiogu.  Ms. Talberg has served in various energy-related consulting, management, and public service roles during her career.  She represents political independents on the Commission.  Other important regulatory events and developments are summarized below.

·Electric Rate Case:  Consumers filed a general electric rate case with the MPSC in September 2012, seeking an annual rate increase of $148 million.  In March 2013, Consumers self-implemented an annual rate increase of $110 million, subject to refund with interest.  The MPSC approved a partial settlement agreement in May 2013, authorizing an annual rate increase of $89 million, based on a 10.3 percent authorized rate of return on equity.  Consumers filed an application in July 2013 requesting that the MPSC find that total revenues collected during self-implementation did not exceed those that would have been collected under final rates and that no refund would be required.

·Gas Rate Case:  In February 2013, Consumers filed an application with the MPSC seeking an annual rate increase of $49 million, based on a 10.5 percent authorized return on equity.  The filing requested authority to recover new investments in customer reliability, deliverability, safety, and system enhancements, and sought approval of several rate adjustment mechanisms.  Subsequent to this filing, Consumers’ projection of non-fuel costs decreased.  As a result, in June 2013, Consumers filed a petition with the MPSC to close the docket or, alternatively, to suspend and extend indefinitely the schedule in this case.  The MPSC approved Consumers’ petition to suspend and extend indefinitely the schedule.

13

·Income Tax Benefits Accounting Application:  In August 2013, Consumers filed an application with the MPSC requesting approval to accelerate the flow-through to electric and gas customers of certain income tax benefits associated primarily with the cost of removal of plant placed in service before 1993.  Under the accounting treatment that Consumers has been using, Consumers has estimated that it would take at least 50 years to flow through these income tax benefits to customers.  In September 2013, the MPSC approved Consumers’ application with modification, authorizing Consumers to return $211 million of income tax benefits over five years to electric customers and $264 million of income tax benefits over 12 years to gas customers.  The MPSC authorized Consumers to implement this accounting treatment effective January 2014.

·Proposals to Recover Investment in Plants:  Consumers has filed two applications with the MPSC to propose alternative methods to recover its investment in seven smaller coal-fueled units that Consumers plans to mothball in 2016 and in three smaller gas-fueled units whose operations Consumers mothballed in 2009.

In August 2013, Consumers filed an application requesting MPSC advanced approval to use standard utility plant retirement accounting in the event of early retirement of these ten units.  Specifically, Consumers requested the MPSC to provide assurance that the full amount of the undepreciated investment, demolition costs, and cost of removal, including a return on the assets, would, upon their early retirement, be recovered through retail electric base rates.

In September 2013, Consumers filed an application with the MPSC requesting approval to issue up to $454 million in securitization bonds through a newly formed subsidiary.  Under Michigan law, electric utilities are permitted to use highly rated, low-cost securitization bonds to finance the recovery of qualified costs.  The qualified costs that Consumers has requested approval to securitize are principally the remaining book value and projected demolition costs of the ten units described above.  If the MPSC approves Consumers’ application and Consumers proceeds with this bond issuance, Consumers will then adjust its retail electric base rates to exclude the revenue requirement associated with these costs.  Consumers estimates that employing this recovery mechanism in place of existing ratemaking treatment would provide initial annual cost savings to full-service customers of $24 million.

·Gas Revenue Decoupling Mechanism:  The gas revenue decoupling mechanism, authorized by the MPSC in its 2009 order in Consumers’ gas rate case and extended through April 2012, allowed Consumers to adjust future gas rates to the degree that actual average weather-adjusted sales per customer differed from the rate order.  In December 2012, the MPSC approved Consumers’ first reconciliation of the gas revenue decoupling mechanism, in which Consumers requested recovery of $16 million from customers for the period June 2010 through May 2011.  The MPSC authorized recovery of the full amount over a three-month period that began in February 2013.

Consumers filed its final reconciliation of the gas revenue decoupling mechanism in August 2012, requesting recovery of $17 million from customers for the period June 2011 through April 2012.  At September 30, 2013, Consumers had a $17 million regulatory asset recorded for gas revenue decoupling for that period.

The 2008 Energy Law limits alternative electric supply to ten percent of Consumers’ weather-adjusted retail sales of the preceding calendar year.  At September 30, 2013, Consumers’ electric deliveries under the ROA program were at the ten percent limit.  In February 2013, a bill was introduced to the Michigan Senate that, if enacted, would revise the 2008 Energy Law and allow customers on the ROA program waiting list to switch their service to an alternative electric supplier.  Presently, the proportion of Consumers’ electric deliveries under the ROA program and on the ROA waiting list is 25 percent.  The

14

bill also proposes an increase in the cap of six percentage points per year from 2014 through 2016.  Consumers is unable to predict the outcome of this legislative proposal.

Environmental regulation is another area of importance for CMS Energy and Consumers, and they are monitoring numerous legislative and regulatory initiatives, including initiatives to regulate greenhouse gases, and related litigation.

In 2012, the EPA published its final MACT emission standards for electric generating units, based on Section 112 of the Clean Air Act, calling the final rule MATS.  Although numerous parties, including the State of Michigan, have sought to extend the deadline of MATS, it is expected to take effect in 2015.  Consumers has received from the MDEQ a one-year extension for MATS and the Michigan Mercury Rule for ten of its coal-fueled units, allowing them to run as presently configured until April 2016.  CMS Energy and Consumers are continuing to assess the impact and cost associated with these standards.

In September 2013, the EPA issued proposed rules to limit carbon dioxide emissions from new fossil-fuel-fired electric generation units.  Also, President Obama has directed the EPA to address greenhouse gas emissions of existing, modified, and reconstructed fossil-fuel-fired steam electric generating units with proposed standards, regulations, or guidelines to be completed by June 1, 2014, and final standards, regulations, or guidelines to be completed by June 1, 2015.  Subsequent state implementation plans are due by June 30, 2016.  Consumers believes that its balanced energy initiative, its present carbon reduction target, and its emphasis on supply diversity will position it favorably to deal with the impact of carbon regulation, but cannot predict the nature or outcome of these proposals.  Consumers will continue to monitor regulatory activity regarding greenhouse gas emissions standards that may affect electric generating units.

FINANCIAL PERFORMANCE

For the nine months ended September 30, 2013, CMS Energy’s net income available to common stockholders was $350 million, and diluted EPS were $1.29.  This compares with net income available to common stockholders of $315 million and diluted EPS of $1.17 for the nine months ended September 30, 2012.  The main factors contributing to CMS Energy’s improved performance in 2013 were increased gas deliveries and the absence, in 2013, of the write-off of Consumers’ electric revenue decoupling mechanism regulatory asset in 2012.

Consumers’ utility operations are seasonal.  The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment, while peak demand for natural gas occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel.  In addition, Consumers’ electric rates, which follow a seasonal rate design, are higher in the summer months than in the remaining months of the year.  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 and Consumers believe that economic conditions in Michigan are improving.  Consumers expects its electric sales to increase annually by about 0.5 to 1.0 percent on average through 2017, driven largely by the continued rise in industrial production.  Excluding the impacts of energy efficiency programs, Consumers expects its electric sales to increase by about 1.0 to 1.5 percent annually through 2017.  Consumers is projecting that its gas sales will remain stable through 2017.  This outlook reflects growth in gas demand offset by energy efficiency and conservation.

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

15

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

Electric deliveries and rate increases:  For the three months ended September 30, 2013, electric delivery revenues decreased $25 million compared with 2012.  This decrease reflected $31 million of lower deliveries, due primarily to milder weather in 2013, offset partially by a $6 million increase in other revenues attributable to a May 2013 rate increase.  Deliveries to end-use customers, excluding deliveries to Consumers’ largest customer, which is on an economic development rate, were 9.4 billion kWh in 2013, a decrease of 0.3 billion kWh, or three percent, compared with 2012.

For the nine months ended September 30, 2013, electric delivery revenues increased $53 million compared with 2012.  This increase reflected the absence, in 2013, of a $59 million charge to write off Consumers’ electric decoupling regulatory asset in 2012, and a $28 million benefit from a May 2013 rate increase that Consumers self-implemented in March 2013.  These increases were offset partially by $34 million of lower deliveries, due primarily to milder weather in 2013.  Deliveries to end-use customers, excluding deliveries to Consumers’ largest customer, which is on an economic development rate, were 26.7 billion kWh in 2013, a decrease of 0.2 billion kWh, or one percent, compared with 2012.

Other income, net of expenses:  For the three months ended September 30, 2013, other income increased $9 million compared with 2012, and for the nine months ended September 30, 2013, other income increased $7 million compared with 2012.  These increases were due primarily to the absence, in 2013, of contributions related to a 2012 Michigan ballot proposal.

Maintenance and other operating expenses:  For the three months ended September 30, 2013, maintenance and other operating expenses decreased $12 million compared with 2012.  This decrease was due to a $10 million reduction in OPEB cost resulting from OPEB Plan changes adopted in July 2013, and a $2 million decrease in other operating expenses.

For the nine months ended September 30, 2013, maintenance and other operating expenses increased $1 million compared with 2012.  This increase reflected the absence, in 2013, of a $14 million recovery associated with Consumers’ canceled coal-fueled plant in 2012.  This increase was offset largely by a $10 million reduction in OPEB cost resulting from OPEB Plan changes adopted in July 2013 and a $3 million reduction in OPEB cost due to favorable OPEB Plan performance.

18

Depreciation and amortization:  For the three months ended September 30, 2013, depreciation and amortization expense increased $5 million compared with 2012, due primarily to increased plant in service, offset partially by lower amortization expenses on certain regulatory assets.

For the nine months ended September 30, 2013, depreciation and amortization expense increased $24 million compared with 2012.  This increase was due primarily to increased plant in service and an increase in depreciation rates that took effect in June 2012, offset partially by lower amortization expense on certain regulatory assets.

General taxes:  For the nine months ended September 30, 2013, general taxes increased $4 million compared with 2012, due primarily to increased property taxes, reflecting higher capital spending.

Income taxes:  For the three months ended September 30, 2013, income taxes decreased $2 million compared with 2012, reflecting lower electric utility earnings for the three months ended September 30, 2013.

For the nine months ended September 30, 2013, income taxes increased $13 million compared with 2012, reflecting higher electric utility earnings for the first nine months of 2013.

Gas deliveries and rate increases:  For the nine months ended September 30, 2013, gas delivery revenues increased $56 million compared with 2012.  This increase reflected a $52 million increase in revenues from higher customer deliveries, due primarily to colder weather in 2013, which were offset partially by the impact on 2012 revenues of the gas revenue decoupling mechanism, and an $8 million benefit from a June 2012 rate increase that Consumers self-implemented in March 2012.  These increases were offset partially by a $4 million decrease in other revenues.  Deliveries to end-use customers were 206 bcf in 2013, an increase of 34 bcf, or 19.8 percent, compared with 2012.

Maintenance and other operating expenses:  For the three months ended September 30, 2013, maintenance and other operating expenses decreased $2 million compared with 2012.  This decrease was due to a $6 million reduction in OPEB cost resulting from OPEB Plan changes adopted in July 2013, offset partially by a $4 million increase in other operating expenses.

For the nine months ended September 30, 2013, maintenance and other operating expenses decreased $3 million compared with 2012.  This decrease was due to a $6 million reduction in OPEB cost resulting from OPEB Plan changes adopted in July 2013 and a $2 million reduction to OPEB cost due to favorable OPEB Plan performance.  These decreases were offset partially by a $5 million increase in other operating expenses.

19

Income taxes:  For the nine months ended September 30, 2013, income taxes increased $21 million compared with 2012, due primarily to higher gas utility earnings for the first nine months of 2013.

For the three months ended September 30, 2013, corporate interest and other net expenses increased $3 million compared with 2012, due to $2 million of early debt retirement costs and a $2 million increase in interest expense, reflecting increased borrowings, offset partially by $1 million of higher earnings at EnerBank and lower expenses.

For the nine months ended September 30, 2013, corporate interest and other net expenses increased $4 million compared with 2012, due to a $5 million increase in interest expense, reflecting increased borrowings, and $2 million of early debt retirement costs, offset partially by a $3 million benefit attributable to higher earnings at EnerBank and lower expenses.

DISCONTINUED OPERATIONS

For the three months ended September 30, 2013 and 2012, the net loss from discontinued operations was less than $1 million.

For the nine months ended September 30, 2013, the net loss from discontinued operations was less than $1 million, compared with income from discontinued operations of $7 million in 2012, reflecting the elimination of a liability related to a prior asset sale.

RETIREMENT BENEFITS

Effective July 1, 2013, CMS Energy and Consumers approved a change to the Medicare drug program provided through their OPEB Plan from an employer-sponsored prescription drug plan with a retiree drug subsidy to an EGWP, to begin on January 1, 2015.  As a result of changes stemming from the Health Care Acts, the EGWP structure can result in reduced costs for employers, without impacting plan participants’ benefit coverage or costs.  Also effective July 1, 2013, CMS Energy and Consumers approved certain benefit changes to the OPEB Plan, to begin on January 1, 2016.  Accordingly, CMS Energy and Consumers performed a remeasurement of the OPEB Plan as of July 1, 2013.  In addition, with the plan remeasurement, the discount rate used to measure the OPEB liability was increased from 4.4 percent at December 31, 2012 to 5.1 percent at July 1, 2013.  Assumptions regarding the expected long-term rate of return on plan assets and the health-care cost trend rate did not change from December 31, 2012 levels.

As a result of these changes, CMS Energy’s (including Consumers’) OPEB liability decreased by $638 million, its OPEB regulatory asset of $580 million was eliminated, and an OPEB regulatory liability of $34 million was established as of July 1, 2013.  CMS Energy’s accumulated other comprehensive loss decreased by $24 million.  CMS Energy’s (including Consumers’) OPEB cost is expected to decrease by $48 million in 2013.  Consumers’ OPEB liability decreased by $614 million, its OPEB regulatory asset of $580 million was eliminated, and an OPEB regulatory liability of $34 million was established as of July 1, 2013.  Consumers’ OPEB cost is expected to decrease by $46 million in 2013.

The decrease in CMS Energy’s and Consumers’ OPEB liabilities was due primarily to the change in the discount rate used to measure the liabilities and other changes in actuarial assumptions, the benefit changes, and the change in the OPEB Plan’s Medicare drug program to the EGWP structure.  Presented in the following table are the components of the decrease in CMS Energy’s and Consumers’ OPEB liabilities at July 1, 2013.

Contribution estimates comprise required amounts and discretionary contributions.  Consumers’ pension and OPEB costs are recoverable through its general ratemaking process.  Actual future costs and contributions will depend on future investment performance, changes in discount rates, and various other factors related to the Pension Plan and OPEB participants.

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 debt covenants and articles of incorporation, and potentially by provisions under the Federal Power Act and the Natural Gas Act and FERC requirements.  For additional details on Consumers’ dividend restrictions, see Note 3, Financings and Capitalization – Dividend Restrictions.  For the nine months ended September 30, 2013, Consumers paid $300 million in common stock dividends to CMS Energy.

CMS Energy has entered into two continuous equity offering programs permitting it to sell, from time to time in “at the market” offerings, common stock having an aggregate sales price of up to $50 million per program.  Under the first program, entered into in 2011, CMS Energy issued common stock and received net proceeds of $20 million in March 2013 and $15 million in each of 2012 and 2011.  In April 2013, CMS Energy entered into the second continuous equity offering program, but has not yet issued any equity under this program.

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

24

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 diminish or otherwise become restricted, however, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending.  CMS Energy and Consumers had the following secured revolving credit facilities available at September 30, 2013:

1 Obligations under this facility are secured by Consumers common stock.

2 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 September 30, 2013, $250 million of accounts receivable were eligible for transfer under this program.

Certain of CMS Energy’s and Consumers’ credit agreements, debt indentures, and other facilities contain covenants that require CMS Energy and Consumers to maintain certain financial ratios, as defined therein.  At September 30, 2013, no events of default had occurred with respect to any financial covenants contained in CMS Energy’s and Consumers’ credit agreements, debt indentures, or other facilities.  CMS Energy and Consumers were each in compliance with these covenants as of September 30, 2013, as presented in the following table:

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; the maximum obligation under indemnities for which such amounts were estimable was $476 million at September 30, 2013.  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 AND GAS UTILITY BUSINESS OUTLOOK AND UNCERTAINTIES

Rate Matters:  Rate matters are critical to Consumers’ electric and gas utility businesses.  For additional details on rate matters, see Note 1, Regulatory Matters.

Future Rate Cases:  In order to minimize increases in customer base rates, Consumers has undertaken several initiatives to reduce costs through a voluntary separation plan in 2012, accelerated pension funding, employee and retiree health-care cost sharing, negotiated labor agreements, information system efficiencies, and productivity improvement programs.  Consumers has also filed certain applications with the MPSC, including the accounting application described in the following paragraph, that, if approved, are expected to result in cost savings for customers.  These initiatives, together with Consumers’ plans to accelerate further cost reductions, should allow Consumers to avoid increasing electric and gas base rates through 2014.  Consumers may reconsider this expectation should its assumptions change regarding the economy or other matters.

Income Tax Benefits Accounting Application:  In August 2013, Consumers filed an application with the MPSC requesting approval to accelerate the flow-through to electric and gas customers of certain income tax benefits associated primarily with the cost of removal of plant placed in service before 1993.  Under the accounting treatment that Consumers has been using, Consumers has estimated that it would take at least 50 years to flow through these income tax benefits to customers.  In September 2013, the MPSC approved Consumers’ application with modification, authorizing Consumers to return $211 million of income tax benefits over five years to electric customers and $264 million of income tax benefits over 12 years to gas customers.  The MPSC authorized Consumers to implement this accounting treatment effective January 2014.

Smart Energy:  Consumers’ grid modernization effort continues.  In August 2012, Consumers began installing smart meters in Muskegon County, Michigan.  One of the functions of smart meters is to allow customers to monitor and manage their energy usage, which Consumers expects will help reduce demand during critical peak times, resulting in lower peak capacity requirements.  The installation of smart meters should also provide for both operational and customer benefits.  As of September 30, 2013, Consumers had upgraded over 125,000 electric residential and small business customers in western Michigan to

26

smart meters.  Consumers is able to read these smart meters remotely; further functionality will continue to be added through mid-2015.  Consumers expects to have installed about 400,000 smart meters throughout western Michigan by the end of 2014.  Consumers also plans to install communication modules on gas meters in areas where Consumers provides both electricity and natural gas to customers.

CONSUMERS ELECTRIC UTILITY BUSINESS OUTLOOK AND UNCERTAINTIES

Balanced Energy Initiative:  Consumers continues to experience increasing demand for electricity due to Michigan’s recovering economy and increased use of air conditioning, consumer electronics, and other electric devices, offset partially by the predicted effects of energy efficiency and conservation.  In July 2012, customers set a new all-time peak demand record of 9,006 MW.

Consumers plans to mothball seven of its smaller coal-fueled units for a period of three years.  In June 2013, MISO approved Consumers’ applications to delay the mothballing of the units by one year, to 2016.  Consumers will continue to evaluate its options for the plants, which include:

·installing more environmental equipment on the units to reduce emissions further in order to meet new environmental standards and continue to operate the units;

·seeking a further extension of compliance deadlines for new environmental standards;

·converting the units to natural gas instead of coal;

·decommissioning the units; or

·a combination of these options, depending on customer needs and market conditions.

With the potential suspension of these plants’ operations and the potential tightening of the MISO capacity market, Consumers could experience a shortfall in generation capacity of up to 1,500 MW in 2016.  In order to address future capacity requirements and growing electric demand in Michigan, Consumers updated its balanced energy initiative, a comprehensive energy resource plan designed to meet the short-term and long-term electricity needs of its customers through:

·energy efficiency;

·demand management;

·expanded use of renewable energy;

·development of new power plants;

·power or generating asset purchases to complement existing generating sources; and

·continued operation or upgrade of existing units.

In December 2012, Consumers announced plans to build a 700-MW gas-fueled electric generating plant at its Thetford complex in Genesee County, Michigan.  In July 2013, Consumers received an air permit for the proposed plant from the MDEQ and, as allowed under the 2008 Energy Law, filed for approval of a certificate of necessity with the MPSC.  Construction of the plant, at an estimated cost of $750 million, is contingent upon obtaining the certificate of necessity and environmental permits.  Consumers expects that the plant would be operational in 2017.

While Consumers continues to move ahead with its plans to build a new gas-fueled electric generating plant, it also issued a solicitation in September 2013 seeking offers from owners of existing gas-fueled electric generating plants located in Michigan’s Lower Peninsula to sell their plants to Consumers.  The purchase by Consumers of one or more existing plants could represent a cost-effective alternative to building a new plant.

Electric Rate Matters:  Consumers has filed two applications with the MPSC to propose alternative methods to recover its investment in seven smaller coal-fueled units that Consumers plans to mothball in 2016 and in three smaller gas-fueled units whose operations Consumers mothballed in 2009.

27

Advanced Accounting Approval:  In August 2013, Consumers filed an application requesting MPSC advanced approval to use standard utility plant retirement accounting in the event of early retirement of these ten units.  Specifically, Consumers requested the MPSC to provide assurance that the full amount of the undepreciated investment, demolition costs, and cost of removal, including a return on the assets, would, upon their early retirement, be recovered through retail electric base rates.

Securitization of Qualified Costs:  In September 2013, Consumers filed an application with the MPSC requesting approval to issue up to $454 million in securitization bonds through a newly formed subsidiary.  Under Michigan law, electric utilities are permitted to use highly rated, low-cost securitization bonds to finance the recovery of qualified costs.  The qualified costs that Consumers has requested approval to securitize are principally the remaining book value and projected demolition costs of the ten units described above.  If the MPSC approves Consumers’ application and Consumers proceeds with this bond issuance, Consumers will then adjust its retail electric base rates to exclude the revenue requirement associated with these costs.  Consumers estimates that employing this recovery mechanism in place of existing ratemaking treatment would provide initial annual cost savings to full-service customers of $24 million.

For additional details on rate matters, see Note 1, Regulatory Matters.

Renewable Energy Plan:  Consumers’ renewable energy plan details how Consumers expects to meet REC and capacity standards prescribed by the 2008 Energy Law.  This law requires Consumers to use RECs in an amount equal to at least ten percent of its electric sales volume (estimated to be 3.3 million RECs annually) in 2015 and each year thereafter.  RECs represent proof that the associated electricity was generated from a renewable energy resource.  Under its renewable energy plan, Consumers expects to meet its renewable energy requirement each year with a combination of newly generated RECs and previously generated RECs carried over from prior years.

The 2008 Energy Law also requires Consumers to obtain 500 MW of new capacity from renewable energy resources by the end of 2015, either through generation resources owned by Consumers or through agreements to purchase capacity from other parties.  To meet its renewable capacity requirements, Consumers expects to add more than 500 MW of owned or contracted renewable capacity.  Through September 2013, Consumers has contracted for the purchase of 302 MW of nameplate capacity from renewable energy suppliers and owns 100 MW of nameplate capacity at its recently constructed Lake Winds® Energy Park.  The combination of the contracted and owned capacity represents 81 percent of the 2015 renewable capacity requirement.  Consumers expects to meet the balance of the requirement through the completion of its Cross Winds® Energy Park, a 105-MW wind park in Tuscola County, Michigan, which is expected to begin operations in late 2014.  Consumers has entered into construction and supply contracts as well as a contract to purchase wind turbine generators for the construction of the Cross Winds® Energy Park.

The extension of federal tax credits for wind projects for which construction begins prior to December 31, 2013 could reduce significantly the cost of meeting the renewable requirements of the 2008 Energy Law.  As a result, Consumers has accelerated the construction of Cross Winds® Energy Park and began construction in October 2013.  Consumers expects to qualify for $100 million to $120 million of federal production tax credits associated with the Cross Winds® Energy Park.  These cost savings, which will be based on the wind project’s production over its first ten years of operation, will be passed on to customers through a reduced renewable energy surcharge or through a reduction in PSCR costs.

Energy Optimization Plan:  The 2008 Energy Law requires Consumers to achieve energy savings equivalent to annual sales reduction targets through at least 2015.  The targets increase annually, with the goal of achieving a six percent reduction in customers’ electricity use and a four percent reduction in customers’ natural gas use by December 31, 2015.  Under its energy optimization plan, Consumers

28

provides its customers with incentives to reduce usage by offering energy audits, rebates and discounts on purchases of highly efficient appliances, and other incentives and programs.  Consumers estimates that, through its gas and electric energy optimization programs, its customers realized $184 million in energy savings during 2012.

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 in recent years.

Consumers expects weather-adjusted electric deliveries to decrease in 2013 by three percent compared with 2012.  Consumers’ outlook for 2013 includes reduced deliveries to its largest customer, which produces energy-related and computer components.  Consumers has a long-term contract with this customer to provide electricity at a discounted rate for economic development purposes.  Excluding this customer, Consumers expects weather-adjusted electric deliveries in 2013 to remain stable compared with 2012.  This outlook reflects Consumers’ belief that economic conditions in Michigan are improving.

Over the next five years, Consumers expects average electric delivery growth of about 0.5 to 1.0 percent annually.  This increase reflects growth in electric demand, offset partially by the predicted effects of energy efficiency programs and appliance efficiency standards.  Actual delivery levels will depend on:

·energy conservation measures and results of energy efficiency programs;

·fluctuations in weather; and

·Michigan economic conditions, including utilization, expansion, or contraction of manufacturing facilities, population trends, and housing activity.

Electric ROA:  A Michigan statute enacted in 2000 allows Consumers’ electric customers to buy electric generation service from Consumers or from an alternative electric supplier.  The 2008 Energy Law revised the statute by limiting alternative electric supply to ten percent of Consumers’ weather-adjusted retail sales of the preceding calendar year.  At September 30, 2013, electric deliveries under the ROA program were at the ten percent limit and alternative electric suppliers were providing 788 MW of generation service to ROA customers.  Of Consumers’ 1.8 million electric customers, 311 customers, or 0.02 percent, purchased electric generation service under the ROA program.  Consumers expects 2013 electric deliveries under the ROA program to be at a similar level to 2012.

In February 2013, a bill was introduced to the Michigan Senate that, if enacted, would revise the 2008 Energy Law and allow customers on the ROA program waiting list to switch their service to an alternative electric supplier.  Presently, the proportion of Consumers’ electric deliveries under the ROA program and on the ROA waiting list is 25 percent.  The bill also proposes an increase in the cap of six percentage points per year from 2014 through 2016.  Consumers is unable to predict the outcome of this legislative proposal.  The Michigan legislature also has conducted hearings on the subject of energy competition.  If a proposal to deregulate electric generation in Michigan were enacted, it could have a material adverse effect on Consumers’ financial results and operations.

Electric Transmission:  In 2011, FERC issued an order in a rulemaking proceeding concerning regional electric transmission planning and cost allocations.  Consumers and several other electric utilities filed a joint petition seeking clarification/rehearing of FERC’s order and opposing the allocation methodology.  In 2012, following FERC’s denial of their requests for clarification/rehearing, Consumers and several other electric utilities filed a petition for review of FERC’s order with the U.S. Court of Appeals for the D.C. Circuit.  In May 2013, Consumers, along with other electric utilities, filed briefs in this matter.

In a related matter, in 2010, MISO filed and FERC approved a tariff revision proposing a cost allocation methodology for a new category of transmission projects.  Under this tariff revision, the cost of these new transmission projects will be spread proportionally across the MISO energy market.  Consumers believes

29

that Michigan customers will bear additional costs under MISO’s tariff without receiving comparable benefits from these projects.  In 2011, Consumers, along with the Michigan Attorney General, ABATE, DTE Electric, and other parties, filed a petition for review of FERC’s order with the U.S. Court of Appeals for the Seventh Circuit following FERC’s denial of their request for rehearing opposing the allocation methodology in the MISO tariff revision.  In June 2013, the Court of Appeals issued an opinion largely affirming FERC’s orders regarding the cost allocation methodology.  In October 2013, the Michigan Attorney General filed, and Consumers and other parties joined, a petition with the U.S. Supreme Court seeking review of the Court of Appeals’ opinion.  Regardless of the final outcome of these appeals, Consumers expects to continue to recover transmission expenses, including those associated with the MISO tariff revision, through the PSCR process.

In 2012, ReliabilityFirst Corporation informed Consumers that Consumers may not be properly registered to meet certain NERC electric reliability standards.  Consumers has assessed its registration status, taking into consideration FERC’s December 2012 order on the definition of a bulk electric system, and in August notified ReliabilityFirst that it is preparing to change its registration.  In light of this order, Consumers is reviewing the classification of its electric distribution assets under FERC’s modified definition of the bulk electric system.  Consumers believes that it would recover any incremental costs that it might incur in connection with the resolution of any issues in this area.

Governor’s Energy Initiative:  Michigan’s governor has instituted a process pursuant to which a series of reports are to be completed addressing energy efficiency, renewable energy, the electricity market and retail open access, and other subjects.  The process is designed to help the governor and other lawmakers determine the state’s next steps regarding energy policies.  Following a series of public hearings, the MPSC and Michigan’s Energy Office Director released four draft reports summarizing the information gathered.  Final reports are expected in November 2013 and the governor expects to make policy recommendations in December 2013.  Consumers has participated actively in this process but cannot predict its outcome.

Electric Environmental Estimates:  Consumers’ operations are subject to various state and federal environmental laws and regulations.  Consumers estimates that it will incur expenditures of $1.0 billion from 2013 through 2017 to continue to comply with the Clean Air Act, Clean Water Act, and numerous state and federal environmental regulations.  Consumers expects to recover these costs in customer rates, but cannot guarantee this result.  Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters:

Air Quality:  In 2011, the EPA released CSAPR, a final replacement rule for CAIR, which requires Michigan and 27 other states to improve air quality by reducing power plant emissions that, according to EPA computer models, contribute to ground-level ozone and fine particle pollution in other downwind states.  In 2012, the U.S. Court of Appeals for the D.C. Circuit voided CSAPR and held that CAIR would remain in place until the EPA promulgated a new rule.  After a request by the EPA for a rehearing was denied, the EPA and other parties sought an appeal to the U.S. Supreme Court, which was granted in June 2013.  A decision by the Supreme Court is not expected until 2014.

In 2012, the EPA published its final MACT emission standards for electric generating units, based on Section 112 of the Clean Air Act, calling the final rule MATS.  Under MATS, all of Consumers’ existing coal-fueled electric generating units are required to add additional controls for hazardous air pollutants.  Existing units, unless granted extensions, must meet the standards by mid-April 2015.  Consumers has received from the MDEQ a one-year extension for MATS and the Michigan Mercury Rule for ten of its coal-fueled units, allowing them to run as presently configured until April 2016.  Consumers does not expect that its other coal-fueled units will require an extension.

30

Presently, Consumers’ strategy to comply with air quality regulations, including CAIR and MATS, involves the installation of emission control equipment at some facilities and the suspension of operations at others; however, Consumers continues to evaluate these rules in conjunction with other EPA rulemakings, litigation, and congressional action.  This evaluation could result in:

·changes in environmental compliance costs related to Consumers’ coal-fueled power plants;

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

·changes in how certain plants are used; and

·the retirement, mothballing, or repowering with an alternative fuel of some of Consumers’ generating units.

The MDEQ renewed and issued the Renewable Operating Permit for the B.C. Cobb plant in August 2011 after an extensive review and a public comment period.  In October 2011, the Sierra Club and the Natural Resources Defense Council filed a petition with the EPA to object to the MDEQ’s issuance of the state Renewable Operating Permit, alleging that the facility is not in compliance with certain provisions of the Clean Air Act, including NSR and Title V.  Consumers responded to these allegations in December 2011.  The EPA could either deny the petition outright or grant the petition and remand the matter to the MDEQ for further action.  The Sierra Club or the Natural Resources Defense Council could also file suit in federal district court seeking EPA action on the petition.  Consumers believes these claims are baseless, but is unable to predict the outcome of this petition.

Fine Particulate Matter:  In December 2012, the EPA finalized a rule that strengthens the air quality standard for fine particulate matter.  Consumers expects short-term impacts to be limited, but this new standard could give rise to air quality concerns in states downwind of Michigan and put pressure on Michigan and other Midwestern states to reduce emissions further.  Given its present strategy for CAIR and MATS compliance, however, Consumers will already be achieving significant reductions in emissions that contribute to the formation of fine particulate matter.

Greenhouse Gases:  In the recent past, there have been numerous legislative and regulatory initiatives at the state, regional, and national levels that involve the regulation of greenhouse gases.  Consumers continues to monitor and comment on these initiatives and to follow 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 September 2013, the EPA issued proposed rules pursuant to Section 111 of the Clean Air Act to limit new gas-fueled electric generating units to 1,000 pounds of carbon dioxide per megawatt-hour and new coal-fueled electric generating units to 1,100 pounds of carbon dioxide per megawatt-hour.  New coal-fueled units would not be able to meet this limit without installing carbon dioxide control equipment using such methods as carbon capture and sequestration.  The proposed rules for new sources are expected to be finalized in 2014.  President Obama has also directed the EPA to address existing, modified, and reconstructed fossil-fuel-fired steam electric generating units with proposed standards, regulations, or guidelines to be completed by June 1, 2014, and final standards, regulations, or guidelines to be completed by June 1, 2015.  Subsequent state implementation plans are due by June 30, 2016.  Consumers believes that its balanced energy initiative, its present carbon reduction target, and its emphasis on supply diversity will position it favorably to deal with the impact of carbon regulation, but cannot predict the nature or outcome of these proposals.  Consumers will continue to monitor regulatory activity regarding greenhouse gas emissions standards that may affect electric generating units.

Litigation, as well as federal laws, EPA regulations regarding greenhouse gases, or similar treaties, state laws, or rules, if enacted or ratified, could require Consumers to replace equipment, install additional emission control equipment, purchase emission allowances, curtail operations, arrange for alternative sources of supply, or take other steps to manage or lower the emission of greenhouse gases.  Although associated capital or operating costs relating to greenhouse gas regulation or legislation could be material

31

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.

CCRs:  In 2010, the EPA proposed rules regulating CCRs, such as coal ash, under the Resource Conservation and Recovery Act.  Recent communications from the EPA stress the need to coordinate CCR rulemaking guidelines for steam electric generating plants under the Clean Water Act.  A final CCR rule could be issued in 2014.  Michigan already regulates CCRs as low-hazard industrial waste.  The EPA proposed a range of alternatives for regulating CCRs, 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 reuse of this product, which would result in a significant increase in the amount of coal ash requiring costly disposal.  Additionally, if the cost of upgrading existing coal ash disposal areas to meet hazardous waste landfill standards were to become economically prohibitive, existing coal ash disposal areas could close, requiring Consumers to find costly alternative arrangements for disposal.  Consumers is unable to predict the impacts from this wide range of possible outcomes, but significant expenditures are likely.

Water:  In 2011, the EPA issued a proposed rule to regulate existing electric generating plant cooling water intake systems under Section 316(b) of the Clean Water Act aimed at reducing alleged harmful impacts on fish and shellfish.  Consumers continues to evaluate this proposed rule and its potential impacts on Consumers’ electric generating plants.  A final rule is expected in November 2013.  The EPA also proposed new regulations in June 2013 that may require physical and/or chemical treatment facilities for wastewater discharges from electric generating plants.  A final rule is expected in 2014.

PCBs:  In 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 approach would aim to phase out equipment containing PCBs by 2025.  Another approach would eliminate an exemption for small equipment containing PCBs.  To comply with any such regulatory actions, Consumers could incur substantial costs associated with existing electrical equipment potentially containing PCBs.  A proposed rule is expected by mid-2014.

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 Rate Case:  In February 2013, Consumers filed an application with the MPSC seeking an annual rate increase of $49 million, based on a 10.5 percent authorized return on equity.  The filing requested authority to recover new investments in customer reliability, deliverability, safety, and system enhancements, and sought approval of several rate adjustment mechanisms.  Subsequent to this filing, Consumers’ projection of non-fuel costs decreased.  As a result, in June 2013, Consumers filed a petition with the MPSC to close the docket or, alternatively, to suspend and extend indefinitely the schedule in this case.  The MPSC approved Consumers’ petition to suspend and extend indefinitely the schedule.

For additional details on rate matters, see Note 1, Regulatory Matters.

Gas Deliveries:  Consumers expects weather-adjusted gas deliveries in 2013 to grow by about three percent compared with 2012.  Over the next five years, Consumers expects average gas deliveries to remain stable.  This outlook reflects modest growth in gas demand offset by the predicted effects of energy efficiency and conservation.  Actual delivery levels from year to year may vary due to:

·fluctuations in weather;

32

·use by power producers;

·availability and development of renewable energy sources;

·changes in gas prices;

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

·the price of competing energy sources or fuels; and

·energy efficiency and conservation impacts.

Gas Transmission:  In May 2013, the MPSC approved Consumers’ application to build a 24-mile, 36-inch natural gas pipeline in St. Joseph and Branch Counties, Michigan.  Consumers expects to spend about $120 million for this project.  Construction of the pipeline is contingent upon obtaining environmental permits.  Consumers expects the pipeline to be operational by the end of 2014.

Gas Transportation:  In July 2012, Trunkline filed a proposal with FERC to cease transporting natural gas through one of its two main transmission pipelines serving Michigan.  More than 60 percent of the natural gas supplied to Consumers’ gas customers is delivered by Trunkline’s two main transmission pipelines.  In August 2012, Consumers filed a motion with FERC to protest against the proposed abandonment on the grounds that it would negatively impact customers and that it could hamper the development of gas-fueled electric generation in Michigan.  Michigan’s governor, the MPSC, and various other parties have also filed protests with FERC.  If Trunkline’s proposal is granted, the abandonment could result in higher gas prices and reduced availability for Michigan gas customers.

Gas Pipeline Safety:  In 2012, President Obama signed the Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011.  The law reauthorizes existing federal pipeline safety programs of the Pipeline and Hazardous Materials Safety Administration through 2015 and it contains provisions mandating:

·an increase in the maximum fine for safety violations to $2 million;

·an increase in the number of pipeline inspectors;

·a study regarding application of integrity management requirements outside of “high consequence areas;”

·a survey regarding existing plans for safe management and replacement of cast iron pipelines;

·prescribed notification and on-site incident response times;

·installation of automatic or remotely controlled shut-off valves on new or replaced pipelines where feasible;

·historical design and construction documentation to verify maximum allowable operating pressures; and

·establishment of new regulations for testing (pressure tests or equivalent methods) of previously untested pipelines in high-consequence areas.

Consumers continues to comply with laws and regulations governing natural gas pipeline safety.  These laws and regulations could cause Consumers to 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.

MPSC Investigations:  In August 2013, the MPSC and the Michigan Attorney General concluded investigations into two natural gas explosions that occurred in Consumers’ gas service territory, in Wayne, Michigan and Royal Oak, Michigan.  Following these investigations, in October 2013 Consumers established a $900,000 fund for customers displaced by gas incidents.  Consumers has also committed to pay $50,000 to fund a safety study and $50,000 to fund natural gas safety training.  In addition, Consumers paid $430,000 in fines to the MPSC.

33

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.

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;

OTHER OUTLOOK AND UNCERTAINTIES

EnerBank:  EnerBank, a wholly owned subsidiary of CMS Capital, is a Utah state-chartered, FDIC-insured industrial bank providing unsecured home improvement loans.  EnerBank represented two percent of CMS Energy’s net assets at September 30, 2013, and four percent of CMS Energy’s net income available to common stockholders for the nine months ended September 30, 2013.  The carrying value of EnerBank’s loan portfolio was $597 million at September 30, 2013.  Its loan portfolio was funded primarily by deposit liabilities of $575 million.  The twelve-month rolling average default rate on loans held by EnerBank has remained stable at 0.7 percent at September 30, 2013.  CMS Energy is required both by law and by contract to provide financial support, including infusing additional capital, to ensure that EnerBank satisfies mandated capital requirements and has sufficient liquidity to operate.  With its self-funding plan, EnerBank has exceeded these requirements historically and exceeded them as of September 30, 2013.

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

Final Tax Regulations:  In September 2013, the Internal Revenue Service and U.S. Treasury Department released final regulations on the deduction and capitalization of expenditures related to tangible property.  These regulations apply to tax years beginning on or after January 1, 2014.  CMS Energy and Consumers are evaluating the effects of the regulations, but do not believe that they will have a significant impact on their consolidated financial statements.

NOTES TO THE UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

These interim consolidated financial statements have been prepared by CMS Energy and Consumers in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  As a result, CMS Energy and Consumers have condensed or omitted certain information and note disclosures normally included in consolidated financial statements prepared in accordance with GAAP.  CMS Energy and Consumers have reclassified certain prior period amounts to conform to the presentation in the current period.  In management’s opinion, the unaudited information contained in this report reflects all adjustments of a normal recurring nature necessary to ensure the fair presentation of financial position, results of operations, and cash flows for the periods presented.  The notes to the unaudited consolidated financial statements and the related unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the 2012 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:REGULATORY MATTERS

Regulatory matters are critical to Consumers.  The Michigan Attorney General, ABATE, the MPSC Staff, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes.  These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief.  The parties also have appealed significant MPSC orders.  Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, 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.

There are multiple appeals pending that involve various issues concerning cost allocation among customers, the allocation of refunds among customer groups, the adequacy of the record evidence supporting the recovery of Smart Energy investments, and other matters.  Consumers is unable to predict the outcome of these appeals.

CONSUMERS ELECTRIC UTILITY

Electric Rate Cases:  In June 2012, the MPSC authorized an annual rate increase of $118 million, based on a 10.3 percent authorized return on equity.  Consumers filed an application in September 2012 requesting that the MPSC find that the total revenues collected during self-implementation did not exceed those that would have been collected under final rates.  In March 2013, the MPSC approved a settlement agreement finding that no refund was required.

In September 2012, Consumers filed an application with the MPSC seeking an annual rate increase of $148 million, based on a 10.5 percent authorized return on equity, in order to recover new investment in system reliability, environmental compliance, and technology enhancements.  In January 2013, Consumers supplemented its electric rate case application to reflect changes to its environmental compliance and generation outage plans, which reduced its requested annual rate increase to $145 million.  In this filing, Consumers also sought approval of several rate adjustment mechanisms.

In March 2013, Consumers self-implemented an annual rate increase of $110 million out of its requested $145 million, subject to refund with interest.  Consumers’ self-implementation required no order by the

51

MSPC, and no intervenors in Consumers’ electric rate case opposed Consumers’ self-implementation amount.  The MPSC approved a partial settlement agreement in May 2013, authorizing an annual rate increase of $89 million, based on a 10.3 percent authorized rate of return on equity.  The rate adjustment mechanisms requested by Consumers were not approved.  In June 2013, in connection with this electric rate case, the MPSC approved Consumers’ application for authority to continue the advance metering infrastructure program and implement a non-transmitting meter provision.

In July 2013, Consumers filed a reconciliation of total revenues collected during self-implementation to those that would have been collected under final rates.  Consumers’ reconciliation indicated that no refund would be required.

Electric Revenue Decoupling Mechanism:  The MPSC’s 2009 order in Consumers’ electric rate case authorized Consumers to implement an electric revenue decoupling mechanism.  This decoupling mechanism allowed Consumers to adjust future electric rates to the degree that actual average sales per customer differed from the rate order.  The MPSC extended the electric revenue decoupling mechanism for a second year in its 2010 order in Consumers’ electric rate case.

In April 2012, the Michigan Court of Appeals ruled that the MPSC lacks statutory authority to approve or direct the use of a revenue decoupling mechanism for electric providers.  Subsequently, in November 2012, the Michigan Court of Appeals ruled in an appeal of the MPSC’s 2010 order in Consumers’ electric rate case.  The Court reversed the portion of the 2010 order related to Consumers’ electric revenue decoupling mechanism and remanded the case to the MPSC for further proceedings related to the revenue decoupling mechanism.  In March 2013, the MSPC issued an order in the remand proceedings, stating that, with the exception of the authorization of the revenue decoupling mechanism, its 2010 order in Consumers’ electric rate case stands as issued.

Big Rock Nuclear Decommissioning:  Consumers had recorded an $85 million regulatory asset for $30 million it paid to Entergy to assume ownership responsibility for the Big Rock ISFSI and for $55 million of nuclear fuel storage costs it incurred as a result of the DOE’s failure to accept nuclear fuel.  Consumers filed a complaint against the DOE in 2002 for this failure.

In 2011, Consumers entered into an agreement with the DOE to settle its claims for $120 million.  Consumers subsequently filed an application with the MPSC requesting authority to utilize $85 million of the settlement amount as recovery of its regulatory asset, and to refund to customers $23 million previously collected through rates for spent nuclear fuel costs.  In December 2012, the MPSC approved this treatment, and Consumers refunded $23 million to customers over the six-month period from January 2013 through June 2013.  Consumers recognized the remaining $12 million of the settlement as a reduction of maintenance and other operating expenses.  In March 2013, a party filed an appeal with the Michigan Court of Appeals to dispute the MPSC’s December 2012 order.

Renewable Energy Plan:  In January 2013, Consumers received a $69 million renewable energy grant for Lake Winds® Energy Park, which began operations in November 2012.  The grant was received from the U.S. Department of Treasury under Section 1603 of the American Recovery and Reinvestment Tax Act of 2009.

As reflected in Consumers’ 2011 biennial renewable energy plan, which the MPSC approved in 2012, this grant reduces Consumers’ cost of complying with the renewable standards prescribed by the 2008 Energy Law and, accordingly, reduces the overall renewable energy surcharge to be collected from customers.  At September 30, 2013, Consumers had a $68 million regulatory liability recorded for the grant.  The regulatory liability will be amortized over the life of Lake Winds® Energy Park.

In May 2013, Consumers filed a revised renewable energy plan that reduced the size and cost of the Cross Winds® Energy Park.  In June 2013, the MPSC issued an order approving Consumers’ 2011 renewable

52

cost reconciliation filing.  In July 2013, Consumers filed its 2012 renewable cost reconciliation and annual report.

Energy Optimization Plan:  In May 2013, Consumers filed its fourth annual report and reconciliation for its energy optimization plan, requesting approval of its energy optimization plan costs for 2012.  In October  2013, Consumers filed a settlement agreement, which, if approved, would authorize Consumers to collect $17 million from customers during 2014 as an incentive payment for exceeding statutory targets under both its gas and electric energy optimization plans during 2012.  In August 2013, Consumers filed its energy optimization plan for the period 2014 through 2017 with the MPSC.

CONSUMERS GAS UTILITY

Gas Revenue Decoupling Mechanism:  The MPSC’s 2009 order in Consumers’ gas rate case authorized Consumers to implement a gas revenue decoupling mechanism.  This mechanism, which the MPSC extended through April 2012 in its 2010 order in Consumers’ gas rate case, allowed Consumers to adjust future gas rates to the degree that actual average weather-adjusted sales per customer differed from the rate order.  This mechanism was not affected by a separate Michigan Court of Appeals decision on electric revenue decoupling.

In December 2012, the MPSC approved Consumers’ reconciliation of the gas revenue decoupling mechanism for the period June 2010 through May 2011 and authorized recovery of $16 million over a three-month period that began in February 2013.  Due to high customer deliveries during this three-month period, Consumers collected more than the amount authorized and refunded the over-collection in August 2013.  In January 2013, ABATE filed an appeal with the Michigan Court of Appeals to dispute the MPSC’s conclusion that Consumers is eligible to recover the portion of the authorized recovery amount allocated to transport customers.

Consumers filed its final reconciliation of the gas revenue decoupling mechanism in August 2012, requesting recovery of $17 million from customers for the period June 2011 through April 2012.  At September 30, 2013, Consumers had a $17 million regulatory asset recorded for gas revenue decoupling for that period.

2:CONTINGENCIES AND COMMITMENTS

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

CMSENERGY 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.  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.

53

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

·In 2005, CMS Energy, CMS MST, and CMS Field Services were named as defendants in a putative class action filed in Kansas state court, Learjet, Inc., et al. v. Oneok, Inc., et al.  The complaint alleges that 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 are seeking statutory full consideration damages consisting of the full consideration paid by plaintiffs for natural gas allegedly purchased from defendants.

·In 2007, a class action complaint, Heartland Regional Medical Center, et al. v. Oneok, Inc. et al., was filed as a putative class action 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 reporting activities.  Plaintiffs are seeking full consideration damages and treble 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.

·Another class action complaint, Newpage Wisconsin System v. CMS ERM, et al., was filed in 2009 in circuit court in Wood County, Wisconsin, against CMS Energy, CMS ERM, Cantera Gas Company, and others.  The plaintiff is seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees.

·In 2005, J.P. Morgan Trust Company, in its capacity as Trustee of the FLI Liquidating Trust, filed an action in Kansas state court against CMS Energy, CMS MST, CMS Field Services, and others.  The complaint alleges various claims under the Kansas Restraint of Trade Act.  The plaintiff is seeking statutory full consideration damages for its purchases of natural gas in 2000 and 2001.

After removal to federal court, all of the cases described above were transferred to the MDL.  In 2010, CMS Energy and Cantera Gas Company were dismissed from the Newpage case.  In 2011, all claims against remaining CMS Energy defendants in the MDL cases were dismissed based on FERC preemption.  Plaintiffs filed appeals in all of the cases.  The issues on appeal were whether the district court erred in dismissing the cases based on FERC preemption and denying the plaintiffs’ motions for leave to amend their complaints to add a federal Sherman Act antitrust claim.  The plaintiffs did not appeal the dismissal of CMS Energy as a defendant in these cases, but other CMS Energy entities remain as defendants.

In April 2013, the U.S. Court of Appeals for the Ninth Circuit reversed the MDL decision and remanded the case to the MDL judge for further proceedings.  The appellate court found that FERC preemption does not apply under the facts of these cases.  The Court affirmed the MDL court’s denial of leave to amend to add federal antitrust claims.

54

In August 2013, the joint defense group in these cases, of which CMS Energy defendants are members, filed a petition with the U.S. Supreme Court in an attempt to overturn the decision of the U.S. Court of Appeals for the Ninth Circuit.  Plaintiffs’ responses to the petition are due in late October 2013.

These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions.  Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s possible loss would be based on widely varying models previously untested in this context.  If the outcome after appeals is unfavorable, these cases could have a material adverse impact on CMS Energy’s liquidity, financial condition, and results of operations.

Bay Harbor:  CMS Energy retained environmental remediation obligations for the collection and treatment of leachate, a liquid consisting of water and other substances, at Bay Harbor after selling its interests in the development in 2002.  Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site.  In 2012, CMS Energy and the MDEQ finalized an agreement that established the final remedies and the future release criteria at the site.  CMS Energy is in the process of completing all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit issued in 2010.  This permit requires renewal every five years.

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 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 under Superfund of the EPA’s response costs incurred at the Bay Harbor site.  CMS Land has communicated to the EPA that it does not believe that this is a valid claim.

CMS Energy has recorded a cumulative charge related to Bay Harbor of $228 million, which includes accretion expense.  At September 30, 2013, CMS Energy had a recorded liability of $55 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.  The undiscounted amount of the remaining obligation is $73 million.  CMS Energy expects to pay $12 million in 2013, $4 million in each of 2014, 2015, 2016, and 2017, 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:

·a significant increase in the cost of 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;

·the nature and extent of contamination;

·delays in the receipt of requested permits;

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

·unanticipated difficulties in meeting the technical commitments in the agreement with the MDEQ;

·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

55

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 January 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea.  The government of Equatorial Guinea claims that CMS Energy owes $142 million in taxes, plus penalties and interest, in connection with the sale.  CMS Energy has concluded that the government’s tax claim is without merit.  The government of Equatorial Guinea indicated through a request for arbitration in October 2011 that it still intends to pursue its claim.  CMS Energy is vigorously contesting the claim, and cannot predict the financial impact or outcome of this matter.

CONSUMERS ELECTRIC UTILITY CONTINGENCIES

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

Cleanup and Solid Waste:  Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA.  Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome.  Consumers estimates that its liability for NREPA sites will be between $4 million and $6 million.  At September 30, 2013, Consumers had a recorded liability of $4 million, the minimum amount in the range of its estimated probable NREPA liability.

Consumers is a potentially responsible party at a number of contaminated sites administered under Superfund.  Superfund liability is joint and several.  In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River Superfund site.  The notification claimed that the EPA has reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site.  In April 2011, Consumers received a follow-up letter from the EPA requesting that Consumers agree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River.  All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability.  In August 2011, the EPA announced that it would proceed with the removal action plan and would continue to pursue potentially responsible parties to perform or pay for some or all of the work.  Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river.

Based on its experience, Consumers estimates that its share of the total liability for other known Superfund sites will be between $2 million and $8 million.  Various factors, including the number of potentially responsible parties involved with each site, affect Consumers’ share of the total liability.  At September 30, 2013, Consumers had a recorded liability of $2 million for its share of the total liability at these sites, the minimum amount in the range of its estimated probable Superfund liability.

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

Ludington PCB:  In 1998, during routine maintenance activities, Consumers identified PCB as a component in certain paint, grout, and sealant materials at Ludington.  Consumers removed and replaced part of the PCB material with non-PCB material.  Consumers has had several communications with the EPA regarding this matter.  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.

56

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

Consumers is engaged in discussions with the EPA on all of these matters.  Depending upon the outcome of these discussions, the EPA could bring legal action against Consumers and/or Consumers could be required to install additional pollution control equipment at some or all of its coal-fueled electric generating plants, surrender emission allowances, engage in Environmental Mitigation 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.  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, but cannot reasonably estimate the extent of cost recovery.  Although Consumers cannot predict the financial impact or outcome of the entirety of these discussions, it does not expect any future loss from civil penalties and/or Environmental Mitigation Projects to be material.

Nuclear Matters:  The matters discussed in this section relate to Consumers’ previously owned nuclear generating plants.  Consumers no longer owns or operates any nuclear generating facilities.

Consumers filed a complaint in 2002 for damages resulting from the DOE’s failure to accept spent nuclear fuel from Palisades and Big Rock.  In 2011, Consumers entered into an agreement with the DOE to settle its claims for $120 million.  As part of this agreement, Consumers also settled its liability to the DOE to fund the disposal of spent nuclear fuel used at Palisades and Big Rock before 1983.  In December 2012, the MPSC issued an order establishing the regulatory treatment of the settlement amount.  In this order, the MPSC also relieved Consumers of its obligation to establish an independent trust fund for the amount that was payable to the DOE prior to the settlement.  In March 2013, a party in this case filed an appeal with the Michigan Court of Appeals to dispute the December 2012 MPSC order.  For further information, see Note 1, Regulatory Matters.

Renewable Energy Matters:  In April 2013, a group of landowners filed a lawsuit alleging, among other things, personal injury and loss of property value and land use as a result of the operations of Lake Winds® Energy Park.  Consumers cannot predict the ultimate financial impact or outcome of this matter.

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.

57

At September 30, 2013, Consumers had a recorded liability of $121 million for its remaining obligations for these sites.  This amount represents the present value of long-term projected costs, using a discount rate of 2.57 percent and an inflation rate of 2.5 percent.  The undiscounted amount of the remaining obligation is $131 million.  Consumers expects to incur remediation and other response activity costs in 2013 and in each of the next four years as follows:

							In Millions
	2013		2014		2015		2016		2017
Consumers
Remediation and other response activity costs	$	8	$	8	$	12	$	12	$	9

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.

Pursuant to orders issued by the MPSC, Consumers defers its MGP-related remediation costs and recovers them from its customers over a ten-year period.  At September 30, 2013, Consumers had a regulatory asset of $150 million related to the MGP sites.

CONSUMERS OTHER CONTINGENCIES

Other Environmental Matters:  Consumers initiated preliminary investigations during 2012 at a number of potentially contaminated sites it presently owns with the intention of determining whether any contamination exists and the extent of any identified contamination.  The sites being investigated include combustion turbine sites, generating sites, compressor stations, and above-ground fuel storage tanks.  Consumers will continue its preliminary investigations at potentially contaminated sites through 2013.  Consumers cannot predict an outcome at this stage of the investigations.

GUARANTEES

Presented in the following table are CMS Energy’s and Consumers’ guarantees at September 30, 2013:

						In Millions
			Maximum			Carrying
Guarantee Description	Issue Date	Expiration Date	Obligation			Amount
CMS Energy, including Consumers
Indemnity obligations from asset sales and other agreements	Various	Various through September 2029	$	476	1	$	16
Guarantees	Various	Various through March 2021	57			-
Consumers
Indemnity obligations and other guarantees	Various	Various through September 2029	$	30		$	1

1The majority of this amount arises from stock and asset sale agreements under which CMS Energy or a subsidiary of CMS Energy, other than Consumers, indemnified the purchaser for losses resulting from various matters, including claims related to tax disputes, claims related to power purchase agreements, and defects in title to the assets or stock sold to the purchaser by CMS Energy subsidiaries.  Except for items described elsewhere in this Note, CMS Energy believes the likelihood of material loss to be remote for the indemnity obligations not recorded as liabilities.

58

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

Guarantee Description	How Guarantee Arose	Events That Would Require Performance
CMS Energy, including Consumers
Indemnity obligations from asset	Stock and asset sale	Findings of misrepresentation,
sales and other agreements	agreements	breach of warranties, tax claims, and
		other specific events or
		circumstances
Guarantees	Normal operating	Nonperformance or non-payment by a
	activity	subsidiary under a related contract
Consumers
Indemnity obligations and	Normal operating	Nonperformance or claims made by a third
other guarantees	activity	party under a related contract

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

OTHER CONTINGENCIES

Other:  In addition to the matters disclosed in this Note and Note 1, 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.

2Obligations under this facility are secured by FMBs of Consumers.

Short-term Borrowings:  Under Consumers’ revolving accounts receivable sales program, Consumers may transfer up to $250 million of accounts receivable, subject to certain eligibility requirements.  These transactions are accounted for as short-term secured borrowings.  At September 30, 2013, $250 million of accounts receivable were eligible for transfer.  During the nine months ended September 30, 2013, Consumers’ average short-term borrowings totaled $7 million, with a weighted-average annual interest rate of 0.94 percent.

Contingently Convertible Securities:  Presented in the following table are the significant terms of CMS Energy’s contingently convertible securities at September 30, 2013:

Security	Maturity	Outstanding (In Millions)	Adjusted Conversion Price	Adjusted Trigger Price
5.50% senior notes	2029	$   172	$     13.74	$      17.86

During 20 of the last 30 trading days ended September 30, 2013, the adjusted trigger-price contingencies were met for the contingently convertible senior notes, and as a result, the senior notes are convertible at the option of the note holders for the three months ending December 31, 2013.  The senior notes, if converted, require CMS Energy to pay cash up to the principal amount of the securities.  Any conversion value in excess of the principal amount can be paid in cash or in shares of CMS Energy’s common stock, at the election of CMS Energy.

Dividend Restrictions:  Under provisions of the Michigan Business Corporation Act, at September 30, 2013, payment of common stock dividends by CMS Energy was limited to $3.4 billion.

Under the provisions of its articles of incorporation, at September 30, 2013, Consumers had $650 million of unrestricted retained earnings available to pay common stock dividends to CMS Energy.  Provisions of the Federal Power Act and the Natural Gas Act appear to restrict dividends payable by Consumers to the amount of Consumers’ retained earnings.  Several decisions from FERC suggest that under a variety of circumstances common stock dividends from Consumers would not be limited to amounts in Consumers’ retained earnings.  Any decision by Consumers to pay common stock dividends in excess of retained earnings would be based on specific facts and circumstances and would result only after a formal regulatory filing process.

For the nine months ended September 30, 2013, CMS Energy received $300 million of common stock dividends from Consumers.

Issuance of Common Stock:  CMS Energy has entered into two continuous equity offering programs permitting it to sell, from time to time in “at the market” offerings, common stock having an aggregate sales price of up to $50 million per program.

Presented in the following table are the transactions that CMS Energy entered into under the first program:

	Number of	Average	Proceeds
	Shares Issued	Price per Share	(In Millions)
June 2011	762,925	$   19.66	$   15
June 2012	650,235	23.07	15
March 2013	735,873	27.18	20
Total	2,149,033	$   23.27	$   50

In April 2013, CMS Energy entered into the second continuous equity offering program, but has not yet issued any equity under this program.

Preferred Stock:  In May 2013, Consumers gave notice of the mandatory redemption of all of its $4.16 preferred stock.  Holders of record as of June 3, 2013 received a redemption price of $103.25 per share, payable July 1, 2013, which represented an aggregate redemption price of $7 million paid to redeem the 68,451 outstanding shares.

4: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, 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.

62

ASSETS AND LIABILITIES MEASURED AT FAIR VALUE ON A RECURRING BASIS

Cash Equivalents:  Cash equivalents and restricted cash equivalents consist of money market funds with daily liquidity.  Short-term debt instruments classified as cash equivalents or restricted cash equivalents on the consolidated balance sheets are not included since they are recorded at amortized cost.

Nonqualified Deferred Compensation Plan Assets and Liabilities:  The nonqualified deferred compensation plan assets consist of mutual funds, which are valued using the daily quoted NAVs that are publicly available and are the basis for transactions to buy or sell shares in each fund.  CMS Energy and Consumers value their nonqualified deferred compensation plan liabilities based on the fair values of the

63

plan assets, as they reflect what is owed to the plan participants in accordance with their investment elections.  CMS Energy and Consumers report the assets in other non-current assets and the liabilities in other non-current liabilities on their consolidated balance sheets.

DB SERP Assets:  CMS Energy and Consumers value their DB SERP assets using a market approach that incorporates quoted market prices.  The DB SERP cash equivalents consist of a money market fund with daily liquidity.  The DB SERP invests in mutual funds that hold primarily fixed-income instruments of varying maturities.  In order to meet their investment objectives, the funds hold investment-grade debt securities, and may invest a portion of their assets in high-yield securities, foreign debt, and derivative instruments.  CMS Energy and Consumers value these funds using the daily quoted NAVs that are publicly available and are the basis for transactions to buy or sell shares in each fund.  CMS Energy and Consumers report their DB SERP assets in other non-current assets on their consolidated balance sheets.  For additional details about DB SERP securities, see Note 5, Financial Instruments.

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.  CMS Energy values its exchange-traded derivative contracts based on Level 1 quoted prices and values other derivatives using Level 2 inputs, including commodity forward prices and credit risk factors.  CMS Energy and Consumers have classified certain derivatives as Level 3 since the fair value measurements incorporate assumptions that cannot be observed or confirmed through market transactions.

The most significant derivatives classified as Level 3 are FTRs held by Consumers.  Consumers uses FTRs to manage price risk related to electricity transmission congestion.  An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges.  FTRs are accounted for as derivatives.  Under regulatory accounting, all changes in fair value associated with FTRs are deferred as regulatory assets or liabilities until the instruments are settled.  Due to the lack of quoted pricing information, Consumers determines the fair value of its FTRs based on Consumers’ average historical settlements.

ASSETS AND LIABILITIES MEASURED AT FAIR VALUE ON A RECURRING BASIS USING SIGNIFICANT LEVEL 3INPUTS

The largest change in the fair values of Level 3 assets and liabilities at CMS Energy and Consumers during the three and nine months ended September 30, 2013 and 2012 was attributable to the FTRs.

5:FINANCIAL INSTRUMENTS

Presented in the following table are the carrying amounts and fair values, by level within the fair value hierarchy, of CMS Energy’s and Consumers’ financial instruments that are not recorded at fair value.  The table does not include information on cash, cash equivalents, short-term accounts and notes receivable, short-term investments, and current liabilities since the carrying amounts of these items approximate their fair values because of their short-term nature.  For information about assets and liabilities recorded at fair value and for additional details regarding the fair value hierarchy, see Note 4, Fair Value Measurements.

2 Includes current portion of long-term debt of $511 million at September 30, 2013 and $519 million at December 31, 2012.

3 Includes current portion of long-term debt of $42 million at September 30, 2013 and $41 million at December 31, 2012.

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.

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 and models may be used that rely on assumptions that cannot be observed or confirmed through market transactions.  CMS Energy includes the value of the conversion features in estimating the fair value of its convertible debt, and incorporates, as appropriate, information on the market prices of CMS Energy common stock.

The effects of third-party credit enhancements are excluded from the fair value measurements of long-term debt.  At September 30, 2013 and December 31, 2012, 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.

EnerBank notes receivable are unsecured consumer installment loans for financing home improvements.

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

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

Loans that are 30 days or more past due are considered delinquent.  The balance of EnerBank’s delinquent consumer loans was $3 million at September 30, 2013 and at December 31, 2012.

At September 30, 2013 and December 31, 2012, $1 million of EnerBank’s loans had been modified as troubled debt restructurings.

Effective July 1, 2013, CMS Energy and Consumers approved a change to the Medicare drug program provided through their OPEB Plan from an employer-sponsored prescription drug plan with a retiree drug subsidy to an EGWP to begin on January 1, 2015.  Also effective July 1, 2013, CMS Energy and Consumers approved certain benefit changes to the OPEB Plan, to begin on January 1, 2016.  Accordingly, CMS Energy and Consumers performed a remeasurement of the OPEB Plan as of July 1, 2013.  In addition, with the plan remeasurement, the discount rate used to measure the OPEB liability was increased from 4.4 percent at December 31, 2012 to 5.1 percent at July 1, 2013.  Assumptions regarding the expected long-term rate of return on plan assets and the health-care cost trend rate did not change from December 31, 2012 levels.

As a result of these changes, CMS Energy’s (including Consumers’) OPEB liability decreased by $638 million, its OPEB regulatory asset of $580 million was eliminated, and an OPEB regulatory liability of $34 million was established as of July 1, 2013.  CMS Energy’s accumulated other comprehensive loss decreased by $24 million.  CMS Energy’s (including Consumers’) OPEB cost is expected to decrease by $48 million in 2013.  Consumers’ OPEB liability decreased by $614 million, its OPEB regulatory asset of $580 million was eliminated, and an OPEB regulatory liability of $34 million was established as of July 1, 2013.  Consumers’ OPEB cost is expected to decrease by $46 million in 2013.

68

CMS Energy and Consumers also remeasured certain deferred tax assets as a result of the approved change to the Medicare drug program.  Effective January 2015, CMS Energy and Consumers will no longer receive Medicare Part D drug subsidies.  Accordingly, CMS Energy (including Consumers) decreased its deferred tax assets by $148 million, reduced its regulatory income tax liabilities by $144 million, and increased its income tax expense by $4 million.  Consumers decreased its deferred tax assets by $144 million, and reduced its regulatory income tax liabilities by an equal amount.

CONTINGENTLY CONVERTIBLE SECURITIES

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

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.

CMS INCENTIVE COMPENSATION PLAN

FOR CMS ENERGY AND CONSUMERS ENERGY OFFICERS

CMS INCENTIVE COMPENSATION PLAN FOR CMS ENERGY AND CONSUMERS ENERGY OFFICERS

I.GENERAL PROVISIONS

1.1Purpose.  The purpose of the CMS Incentive Compensation Plan (“CMSICP” or “Plan”) is to:

(a)Provide an equitable and competitive level of compensation that will permit CMS Energy and Consumers Energy to attract, retain and motivate Officers.

(b)No payments to Officers in the form of incentive compensation shall be made unless pursuant to a plan approved by the Committee on Compensation and Human Resources of the Board of Directors of CMS Energy and after express approval of the Committee.  This plan shall be administered by the President and CEO of CMS Energy and the Benefit Administration Committee.

1.2Effective Date.  The initial effective date of the Plan is January 1, 2004.  The Plan, as described herein, is amended and restated effective as of January 1, 2014.

1.3Definitions.  As used in this Plan, the following terms have the meaning described below:

(a)“Annual Award” means an annual incentive award granted under the CMSICP.

(b)“Base Salary” means the base salary on January 1 of a Performance Year, except as impacted by a Change in Status as defined in Article V.  For purposes of the Plan, an Officer’s Base Salary must be subject to annual review and annual approval by the Committee.

(c)“Benefit Administration Committee” means the committee as appointed by the Chief Executive Officer and Chief Financial Officer of CMS Energy Corporation to act as the Plan Administrator in accordance with authority granted by the Board of Directors.

(d)“CMS Energy” means CMS Energy Corporation.

(e)“Code” means the Internal Revenue Code of 1986, as amended.

(f)“Code Section 162(m) Employee” means a “covered employee” as that term is defined under Code Section 162(m).  Generally, this is the CEO and the three highest paid executive officers (other than the CEO and the CFO) of the corporation.

1

(g)“Committee” means the Committee on Compensation and Human Resources of the Board of Directors of CMS Energy Corporation.

(h)“Company” means CMS Energy.

(i)“Consumers Energy” means Consumers Energy Company, a wholly owned subsidiary of CMS Energy.

(j)“Deferred Annual Award” means the amount deferred pursuant to Section 4.2.

(k)“Disability” means that a participant has terminated employment with the Company or Consumers Energy and is disabled, as that term is defined under Code Section 409A and any applicable regulations.

(l)“Leave of Absence” for purposes of this Plan means a leave of absence that has been approved by the Company.

(m)“Officer” means a United States of America employee of the Company or Consumers Energy in Salary Grade “E-3” or higher.

(s)“Retirement” means that a Plan participant is no longer an active Officer and qualifies for a retirement benefit other than a deferred vested retirement benefit under the Pension Plan.  For a participant ineligible for coverage under the Pension Plan and covered instead under the Defined

Company Contribution Plan, retirement occurs when there is a Separation from Service on or after age 55 with 5 or more years of service.

(t)“Separation from Service” means an Officer retires or otherwise has a separation from service from the Company as defined under Code Section 409A and any applicable regulations.  The Plan Administrator will determine, consistent with the requirements of Code Section 409A and any applicable regulations, to what extent a person on a leave of absence, including on paid sick leave pursuant to Company policy, has incurred a Separation from Service.  Notwithstanding the above, a Separation from Service will occur consistent with the Regulation 1.409A-1(h) when it is reasonably anticipated that the level of service provided by the Officer will be no more than 45% of the average level of bona fide service performed by the Officer over the immediately preceding 36 month period.

(u)“Subsidiary” means any direct or indirect subsidiary of the Company.

1.4Eligibility.  Officers of CMS Energy and/or Consumers Energy who do not participate in a broad based incentive plan contingent upon objectives and performance unique to the Officers’ Subsidiary, affiliate, site and/or business unit, are eligible for participation in the CMSICP. An individual listed on the Company payroll records as a contract employee is not eligible for this Plan.

1.5Administration of the Plan.

(a)The Plan is administered by the President and Chief Executive Officer of CMS Energy under the general direction of the Committee.

(b)The Committee will normally approve performance goals in January of the Performance Year, but no later than March 30th of the Performance Year.

(c)The Committee, no later than March 1st of the calendar year following the Performance Year, will review for approval proposed Annual Awards for the total of all CMSICP Officer participants, as recommended by the President and CEO of CMS Energy.  All proposed Annual Awards are subject to approval of the Committee.  Before the payment of any Annual Awards, the Company’s outside auditors and the Committee will certify in writing that the performance goals were in fact satisfied in accordance with Code Section 162(m).

(d)The Committee reserves the right to modify the performance goals with respect to unforeseeable circumstances or otherwise exercise discretion with respect to proposed Annual Awards as it deems necessary to maintain the spirit and intent of the CMSICP, provided that such discretion will be to decrease or eliminate, not increase, Annual Awards in the case of any

3

Code Section 162(m) Employee.  The Committee also reserves the right in its discretion to not pay Annual Awards for a Performance Year.  All decisions of the Committee are final.

II.CORPORATE PERFORMANCE GOALS

2.1In General.  Corporate performance goals are established in two areas:  (1) the adjusted net income per outstanding CMS Energy share (EPS); and (2) the Cash Flow of CMS Energy (OCF).

2.2Plan Performance Factor.  The plan performance factor used to calculate an Annual Award is based on the results of the corporate performance goals and is capped at two times the standard award amount.  The Plan Performance Factor is established in a table relating specific performance results in the areas of EPS and OCF to specific performance goals. This table shall be created by the Committee for each Performance Year.

III.ANNUAL AWARD FORMULA

3.1Annual Awards.  Annual Awards for each eligible Officer will be based upon a percentage of the Officer’s Base Salary for the Performance Year times the Plan performance factor for the year as determined under 2.2 above.  The standard award percentage for each eligible Officer will be approved annually by the Committee for each Performance Year. The maximum amount that can be awarded under this Plan for any Code Section 162(m) Employee will not exceed $2.5 Million in any one Performance Year.  The total amount of a CMSICP participant Officer’s Annual Award shall be computed according to the annual award formula set forth in Section 3.2.

3.2Calculation of Award.  Annual Awards for Officer CMSICP participants will be calculated and made as follows:

Annual Award = Base Salary times

Standard Award Percentage times Plan Performance Factor

In addition, each Annual Award for Officers of Consumers Energy Company may be modified based on the results achieved for the Consumers Energy Annual Employee Incentive Compensation Plan.  If the Consumers Energy Annual Employee Incentive Compensation Plan does not pay out an operational award for the same Performance Year, then the Annual Award, if any, earned under this Plan will be reduced by 10%.  If the Consumers Energy Annual Employee Incentive Compensation Plan pays out an operational award for the same Performance Year based on achievement of some of the established objectives, but not at the maximum award percentage, then there is no modification of awards

4

under this Plan.  If however, the Consumers Energy Annual Employee Incentive Compensation Plan pays out an operational award at the maximum award percentage for the same Performance Year based on achievement of the established objectives, then the Annual Award, if any, earned under this Plan will be increased by up to 10%, provided, however, that no such increase will cause the Annual Award to exceed the maximum of two times the standard award amount, or exceed the maximum payout for a Code Section 162(m) Employee.

IV.PAYMENT OF ANNUAL AWARDS

4.1Cash Annual Award.  All Annual Awards for a Performance Year will be paid in cash after certification by the outside auditors of the Company and the Committee that the performance goals have been satisfied, but not later than March 15th of the calendar year following the Performance Year provided that the Annual Award for a particular Performance Year has not been deferred voluntarily pursuant to Section 4.2. The amounts required by law to be withheld for income and employment taxes will be deducted from the Annual Award payments.  All Annual Awards become the obligation of the company on whose payroll the Officer is enrolled at the time the Committee makes the Annual Award.

4.2Deferred Annual Awards.

(a)The payment of all or any portion (rounded to an even multiple of 10%) of a cash Annual Award may be deferred voluntarily at the election of an individual Plan participant in salary grades E-3 – E-9.  Any such deferral will be net of any applicable FICA or FUTA taxes.  A separate irrevocable election must be made prior to the Performance Year.  Any Annual Award made by the Committee after termination of employment of a participant or retirement of a participant will be paid in accordance with any deferral election made within the enrollment period.

(b)At the time the participant makes a deferral election he or she must select the payment options (including the Payment Event as set forth at (c) below and the Payment Term as set forth at (d) below) applicable to the Deferred Annual Award for the Performance Year, as well as any earnings or income attributable to such amounts.  The payment options elected will apply only to that year’s Deferred Annual Award and will not apply to any previous Deferred Annual Award or to any subsequent Deferred Annual Award.  Any participant who elects to defer all or a portion of an Annual Award and who fails to select a Payment Event or a Payment Term will be presumed to have elected a Payment Event of Separation from Service in accordance with paragraph (c)(i) below and/or a Payment Term of a single sum.

5

(c)The Payment Event elected can be either:

(i)Separation from Service for any reason other than death.  Payment will be made, or begin, in the later of: (1) January of the year following the year of the Separation from Service; or (2) the seventh month after the month of the Separation from Service.  Later installments, if any, will be paid in January of the succeeding years;

(ii)Payment upon attainment of a date certain that is more than 1 year after the last day of the applicable Performance Year.  Later installments, if any, will be paid in January of the succeeding years; or

(iii)The earlier of (i) or (ii) above.

(d)Payment Term.  At the time of electing to defer an Annual Award, the participant must also elect how he or she wishes to receive any such payment from among the following options (the participant may elect a separate Payment Term for each Payment Event elected):

(i)Payment in a single sum upon occurrence of the Payment Event.

(ii)Payment of a series of annual installment payments over a period from two (2) years to fifteen (15) years following the Payment Event.  Each installment payment shall be equal to a fractional amount of the balance in the account the numerator of which is one and the denominator of which is the number of installment payments remaining.  Although initially such installment payments will be identical, actual payments may vary based upon investment performance.  For example, a series of 5 installment payments will result in a payout of 1/5 of the account balance in the first installment, 1/4 of the account balance (including investment gains or losses since the first installment date) in the second installment, etc.

(e)Changes to Payment Options.  Once a payment option has been elected, subsequent changes which would accelerate the receipt of benefits from the Plan are not permitted, except that the Plan Administrator may at its discretion accelerate payments to the extent permitted by Code Section 409A and applicable regulations.  A subsequent election to change the payment options related to a Payment Event, in order to delay a payment or to change the form of a payment, can only be made when all of the following conditions are satisfied:

6

(i)such election may not take effect until at least 12 months after the date on which the election is made;

(ii)the payment(s) with respect to which such election is made is deferred for a period of not less than 5 years from the date such payment would otherwise have been made (or, in the case of installment payments under Section 4.2(d)(ii), 5 years from the date the first installment was scheduled to be paid); and

(iii)such election must be made not less than 12 months before the date the payment was previously scheduled to be made (or, in the case of installment payments under Section 4.2(d)(ii), 12 months before the first installment was scheduled to be paid), if the participant’s previous commencement date was a specified date.

(f)Investments. At the time of electing to voluntarily defer payment, the participant must elect how the Deferred Annual Award will be treated by the Company or Consumers Energy.  To the extent that any amounts deferred are placed in a rabbi trust with an independent record keeper, a participant who has previously deferred amounts under this Plan will automatically have his or her existing investment profile apply to this deferral also.  All determinations of the available investment options by the Plan Administrator are final and binding upon participants.  A participant may change the investment elections at any time prior to the payment of the benefit, subject to any restrictions imposed by the Plan Administrator, the plan record keeper or by any applicable laws and regulations.  A participant not making an election will have amounts deferred treated as if in a Lifestyle Fund under the Savings Plan for Employees of Consumers Energy and other CMS Energy Companies (the “Savings Plan”) applicable to the participant’s age 65, rounded up, or such other investment as determined by the Benefit Administration Committee.  All gains and losses will be based upon the performance of the investments selected by the participant from the date the deferral is first credited to the nominal account.  If the Company elects to fund its obligation as discussed below, then investment performance will be based on the balance as determined by the record keeper.

(g)The amount of any Deferred Annual Award is to be satisfied from the general corporate funds of the company on whose payroll the Plan participant was enrolled prior to the payout beginning and are subject to the claims of general creditors.  This is an unfunded nonqualified deferred compensation plan.  To the extent the Company or Consumers Energy, as applicable, elects to place funds with a trustee to pay its future obligations under this Plan, such amounts are placed for the convenience of the Company or Consumers Energy, remain the property of the Company or Consumers Energy and the participant shall have no right to such funds

7

until properly paid in accordance with the provisions of this Plan.  For administrative ease and convenience, such amounts may be referred to as participant accounts, but as such are a notional account only and are not the property of the participant.  Such amounts remain subject to the claims of the creditors of the Company or Consumers Energy.

(h)Payment in the Event of an Unforeseeable Emergency. The participant may request that payments commence immediately upon the occurrence of an unforeseeable emergency as that term is defined in Code Section 409A and any applicable regulations.  Generally, an unforeseeable emergency is a severe financial hardship resulting from an illness or accident of the participant or the participant’s spouse or dependent, loss of the participant’s property due to casualty, or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the participant.  A distribution on account of unforeseeable emergency may not be made to the extent that such emergency is or may be relieved through reimbursement or compensation from insurance or otherwise, by liquidation of the participant’s assets (without causing severe financial hardship), or by cessation of deferrals under this arrangement, the Savings Plan or other arrangements. Distributions because of an unforeseeable emergency shall not exceed the amount permitted under Section 409A and accordingly are limited to the amount reasonably necessary to satisfy the emergency need (after use of insurance proceeds, liquidation of assets, etc.) plus an amount to pay taxes reasonably anticipated as a result of the distribution. In the event any payment is made due to an unforeseeable emergency, all deferral elections for the current Performance Year will cease and the participant will not be eligible to make any deferral elections under this Plan for the following Performance Year.  For any participant receiving a hardship withdrawal under the Savings Plan, all deferral elections under this Plan for the current Performance Year will cease and the participant will not be eligible to make any deferral elections under this Plan for the following Performance Year.

4.3Payment in the Event of Death.

(a)A participant may name the beneficiary of his or her choice on a beneficiary form provided by the Company or record keeper, and the beneficiary shall receive, within 90 days of the participant’s death, in a single sum, all payments credited to the participant in the event that the participant dies prior to receipt of Deferred Annual Awards.  If a beneficiary is not named or does not survive the participant, the payment will be made to the participant’s estate. In no event may any recipient designate a year of payment for an amount payable upon the death of the participant.

8

(b)A participant may change beneficiaries at any time, and the change will be effective as of the date the plan record keeper or Company accepts the form as complete.  Neither the Company nor Consumers Energy will be liable for any payments made before receipt and acceptance of a written beneficiary request.

V.CHANGE OF STATUS

Payments in the event of a change in status will not be made if no Annual Awards are made for the Performance Year.

5.1Pro-Rata Annual Awards.  A new Officer participant, whether hired or promoted to the position, or an Officer promoted to a higher salary grade during the Performance Year will receive a pro rata Annual Award based on the percentage of the Performance Year in which the Officer is in a particular salary grade.  An Officer participant whose salary grade has been lowered, but whose employment is not terminated during the Performance Year will receive a pro rata Annual Award based on the percentage of the Performance Year in which the Officer is in a particular salary grade.

5.2Termination.  An Officer participant whose employment is terminated pursuant to a violation of the Company code of conduct or other corporate policies will not be considered for or receive an Annual Award.

5.3Resignation.  An Officer participant who resigns prior to payment (during or after a Performance Year) will not be eligible for an Annual Award.  If the resignation is due to reasons such as a downsizing or reorganization, or the ill health of the Officer or ill health in the immediate family, the Officer may petition the Plan Administrator and may be considered, in the discretion of the Plan Administrator, for a pro rata Annual Award.  The Plan Administrator’s decision to approve or deny the request for a pro rata Annual Award shall be final.

5.4Death, Disability, Retirement, Leave of Absence.  An Officer participant whose status as an active employee is changed during the Performance Year due to death, Disability, Retirement, or Leave of Absence will receive a pro rata Annual Award.  An Officer participant whose employment is terminated following the Performance Year but prior to payment due to death, Disability or Retirement will continue to be eligible for an Annual Award for the Performance Year.  Any such payment or Annual Award payable due to the death of the Officer participant will be made to the named beneficiary, or if no beneficiary is named or if the beneficiary doesn’t survive the Officer participant, then to the Officer participant’s estate no later than March 15 following the applicable Performance Year.  Notwithstanding the above, an Officer participant who retires, is on Disability or Leave of Absence and who becomes employed by a competitor of CMS Energy or Consumers Energy or their subsidiaries or affiliates prior to award payout will forfeit all rights to an Annual Award, unless prior approval of

9

such employment has been granted by the Committee.  A “competitor” shall mean an entity engaged in the business of (1) selling (a) electric power or natural gas at retail or wholesale within the State of Michigan or (b) electric power at wholesale within the market area in which an electric generating plant owned by a subsidiary or affiliate of CMS Energy is located or (2) developing an electric generating plant within the State of Michigan or a market area in which an electric generating plant owned by a subsidiary or affiliate of CMS Energy is located.

5.5Clawback.

(a)If, due to a restatement of CMS Energy’s or an affiliate’s publicly disclosed financial statements or otherwise, an Officer is subject to an obligation to make a repayment or return of benefits to CMS Energy or an affiliate pursuant to a clawback provision contained in this Plan, a supplemental executive retirement plan, the Performance Incentive Stock Plan, or any other benefit plan (a “benefit plan clawback provision”) of the Company, the Committee may determine that it shall be a precondition to the payment of any award under this Plan, that the Officer fully repay or return to the Company any amounts owing under such benefit plan clawback provision (taking into account the requirements of Code Section 409A, to extent applicable).  Any and all awards under this Plan are further subject to any provision of law, which may require the Officer to forfeit or return any benefits provided hereunder, in the event of a restatement of the Company’s publicly disclosed accounting statements or other illegal act, whether required by Section 304 of the Sarbanes-Oxley Act of 2002, Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, federal securities law (including any rule or regulation promulgated by the Securities and Exchange Commission), any state law, or any rule or regulation promulgated by the applicable listing exchange or system on which the Company lists its traded shares.

(b)To the degree any benefits hereunder are not otherwise forfeitable pursuant to the preceding sentences of this Section 5.5, the Board or a Committee delegated authority by the Board (“delegated Committee”), may require the Officer to return to the Company or forfeit any amounts granted under this Plan, if:

1.the grant of such compensation was predicated upon achieving certain financial results which were subsequently the subject of a substantial accounting restatement of the Company’s financial statements filed under the securities laws (a “financial restatement”),

2.a lower payout or Annual Award (“reduced financial results”), would have occurred based upon the financial restatement, and

10

3.in the reasonable opinion of the Board or the delegated Committee, the circumstances of the financial restatement justify such a modification of the Annual Award.  Such circumstances may include, but are not limited to, whether the financial restatement was caused by misconduct, whether the financial restatement affected more than one period and the reduced financial results in one period were offset by increased financial results in another period, the timing of the financial restatement or any required repayment, and other relevant factors.

Unless otherwise required by law, the provisions of this Subsection (b) relating to the return of previously paid Plan benefits shall not apply unless a claim is made therefore by the Company within three years of the payment of such benefits.

(c)The Board or delegated Committee shall also have the discretion to require a clawback in the event of a mistake or accounting error in the calculation of a benefit or an award that results in a benefit to an eligible individual to which he/she was not otherwise entitled.  The rights set forth in this Plan concerning the right of the Company to a clawback are in addition to any other rights to recovery or damages available at law or equity and are not a limitation of such rights.

VI.MISCELLANEOUS

6.1Impact on Benefit Plans.  Payments made under the Plan will be considered as earnings for the Supplemental Executive Retirement Plans but not for purposes of the Employees’ Savings Plan, Pension Plan, or other Officer benefit programs.

6.2Impact on Employment.  Neither the adoption of the Plan nor the granting of any Annual Award under the Plan will be deemed to create any right in any individual to be retained or continued in the employment of the Company or any corporation within the Company’s control group.

6.3Termination or Amendment of the Plan.  The Board of Directors of CMS Energy may amend or terminate the Plan at any time.  Upon termination, any Deferred Annual Award accrued under the Plan will remain in the Plan and be paid out in accordance with the payment options previously selected.  The Plan Administrator is authorized to make any amendments that are deemed necessary or desirable to comply with any applicable laws, regulations or orders or as may be advised by counsel or to clarify the terms and operation of the Plan.  The Company may terminate the Plan and accelerate payment of any deferred benefits under the Plan if it acts consistent in all respects with the requirements of Code Section 409A and any applicable regulations with respect to when a terminated plan may accelerate payment to a participant.

11

6.4Governing Law.  The Plan will be governed and construed in accordance with the laws of the State of Michigan.

6.5Dispute Resolution.  Any disputes related to the Plan must be brought to the Plan Administrator.  The Plan Administrator is granted full discretionary authority to apply the terms of the Plan, make administrative rulings, interpret the Plan and make any other determinations with respect to the Plan.  If the Plan Administrator makes an adverse determination and the participant disagrees with or wishes to appeal the determination, the participant must appeal the decision to the Plan Administrator, in writing and not later than 60 days from when the determination was mailed to the participant.  If the participant does not timely appeal the original determination, the participant has no further rights under the Plan with respect to the matter presented in the claim.  If the participant appeals the original determination and that appeal does not result in a mutually agreeable resolution, then the dispute shall be subject to final and binding arbitration before a single arbitrator selected by the parties to be conducted in Jackson, Michigan, provided the participant makes such request for arbitration in writing within 30 days of the final decision by the Plan Administrator. The arbitration will be conducted and finished within 90 days of the selection of the arbitrator.  The parties shall share equally the cost of the arbitrator and of conducting the arbitration proceeding, but each party shall bear the cost of its own legal counsel and experts and other out-of-pocket expenditures.  The arbitrator must use an arbitrary and capricious standard of review when considering any determinations and findings by the Plan Administrator.

VII.AMENDMENT TO REFLECT CODE SECTION 409A

7.1Code Section 409A.  This Plan has been amended, effective as of January 1, 2005, to comply with the requirements of Code Section 409A.  To the extent counsel determines additional amendments may be reasonable or desirable in order to comply with Code Section 409A, and any other applicable rules, laws and regulations, such changes shall be authorized with the approval of the Plan Administrator.

Contingently Convertible Securities

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

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.

Regulatory Matters

1:REGULATORY MATTERS

Regulatory matters are critical to Consumers.  The Michigan Attorney General, ABATE, the MPSC Staff, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes.  These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief.  The parties also have appealed significant MPSC orders.  Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, 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.

There are multiple appeals pending that involve various issues concerning cost allocation among customers, the allocation of refunds among customer groups, the adequacy of the record evidence supporting the recovery of Smart Energy investments, and other matters.  Consumers is unable to predict the outcome of these appeals.

Consumers Electric Utility

Electric Rate Cases:  In June 2012, the MPSC authorized an annual rate increase of $118 million, based on a 10.3 percent authorized return on equity.  Consumers filed an application in September 2012 requesting that the MPSC find that the total revenues collected during self-implementation did not exceed those that would have been collected under final rates.  In March2013, the MPSC approved a settlement agreement finding that no refund was required.

In September 2012, Consumers filed an application with the MPSC seeking an annual rate increase of $148 million, based on a 10.5 percent authorized return on equity, in order to recover new investment in system reliability, environmental compliance, and technology enhancements.  In January 2013, Consumers supplemented its electric rate case application to reflect changes to its environmental compliance and generation outage plans, which reduced its requested annual rate increase to $145 million.  In this filing, Consumers also sought approval of several rate adjustment mechanisms.

In March 2013, Consumers self-implemented an annual rate increase of $110 million out of its requested $145 million, subject to refund with interest.  Consumers’ self-implementation required no order by the MSPC, and no intervenors in Consumers’ electric rate case opposed Consumers’ self-implementation amount.  The MPSC approved a partial settlement agreement in May 2013, authorizing an annual rate increase of $89 million, based on a 10.3 percent authorized rate of return on equity.  The rate adjustment mechanisms requested by Consumers were not approved.  In June 2013, in connection with this electric rate case, the MPSC approved Consumers’ application for authority to continue the advance metering infrastructure program and implement a non‑transmitting meter provision.

In July 2013, Consumers filed a reconciliation of total revenues collected during self-implementation to those that would have been collected under final rates.  Consumers’ reconciliation indicated that no refund would be required.

Electric Revenue Decoupling Mechanism:The MPSC’s 2009 order in Consumers’ electric rate case authorized Consumers to implement an electric revenue decoupling mechanism.  This decoupling mechanism allowed Consumers to adjust future electric rates to the degree that actual average sales per customer differed from the rate order.  The MPSC extended the electric revenue decoupling mechanism for a second year in its 2010 order in Consumers’ electric rate case.

In April 2012, the Michigan Court of Appeals ruled that the MPSC lacks statutory authority to approve or direct the use of a revenue decoupling mechanism for electric providers.  Subsequently, in November 2012, the Michigan Court of Appeals ruled in an appeal of the MPSC’s 2010 order in Consumers’ electric rate case.  The Court reversed the portion of the 2010 order related to Consumers’ electric revenue decoupling mechanism and remanded the case to the MPSC for further proceedings related to the revenue decoupling mechanism.  In March 2013, the MSPC issued an order in the remand proceedings, stating that, with the exception of the authorization of the revenuedecoupling mechanism, its 2010 order in Consumers’ electric rate case stands as issued.

Big Rock Nuclear Decommissioning:Consumers had recorded an $85 million regulatory asset for $30 million it paid to Entergy to assume ownership responsibility for the Big Rock ISFSI and for $55 million of nuclear fuel storage costs it incurred as a result of the DOE’s failure to accept nuclear fuel.  Consumers filed a complaint against the DOE in 2002 for this failure.

In 2011, Consumers entered into an agreement with the DOE to settle its claims for $120 million.  Consumers subsequently filed an application with the MPSC requesting authority to utilize $85 million of the settlement amount as recovery of its regulatory asset, and to refund to customers $23 million previously collected through rates for spent nuclear fuel costs.  In December 2012, the MPSC approved this treatment, and Consumers refunded $23 million to customers over the six-month period from January 2013 through June 2013.  Consumers recognized the remaining $12 million of the settlement as a reduction of maintenance and other operating expenses.  In March 2013, a party filed an appeal with the Michigan Court of Appeals to dispute the MPSC’s December 2012 order.

Renewable Energy Plan:  In January 2013, Consumers received a $69 million renewable energy grant for Lake Winds® Energy Park, which began operations in November 2012.  The grant was received from the U.S. Department of Treasury under Section 1603 of the American Recovery and Reinvestment Tax Act of 2009.

As reflected in Consumers’ 2011 biennial renewable energy plan, which the MPSC approved in 2012, this grant reduces Consumers’ cost of complying with the renewable standards prescribed by the 2008 Energy Law and, accordingly, reduces the overall renewable energy surcharge to be collected from customers.  At September 30, 2013, Consumers had a $68million regulatory liability recorded for the grant.  The regulatory liability will be amortized over the life of Lake Winds® Energy Park.

In May 2013, Consumers filed a revised renewable energy plan that reduced the size and cost of the Cross Winds® Energy Park.  In June2013, the MPSC issued an order approving Consumers’ 2011 renewable cost reconciliation filing.  In July2013, Consumers filed its 2012 renewable cost reconciliation and annual report.

Energy Optimization Plan:In May 2013, Consumers filed its fourth annual report and reconciliation for its energy optimization plan, requesting approval of its energy optimization plan costs for 2012.  In October  2013, Consumers filed a settlement agreement, which, if approved, would authorize Consumers to collect $17 million from customers during 2014 as an incentive payment for exceeding statutory targets under both its gas and electric energy optimization plans during 2012.  In August 2013, Consumers filed its energy optimization plan for the period 2014 through 2017 with the MPSC.

Consumers Gas Utility

Gas Revenue Decoupling Mechanism:The MPSC’s 2009 order in Consumers’ gas rate case authorized Consumers to implement a gas revenue decoupling mechanism.  This mechanism, which the MPSC extended through April 2012 in its 2010 order in Consumers’ gas rate case, allowed Consumers to adjust future gas rates to the degree that actual average weather-adjusted sales per customer differed from the rate order.  This mechanism was not affected by a separate Michigan Court of Appeals decision on electric revenue decoupling.

In December 2012, the MPSC approved Consumers’ reconciliation of the gas revenue decoupling mechanism for the period June 2010 through May 2011 and authorized recovery of $16 million over a three-month period that began in February 2013.  Due to high customer deliveries during this three-month period, Consumers collected more than the amount authorized and refunded the over-collection in August 2013.  In January 2013, ABATE filed an appeal with the Michigan Court of Appeals to dispute the MPSC’s conclusion that Consumers is eligible to recover the portion of the authorized recovery amount allocated to transport customers.

Consumers filed its final reconciliation of the gas revenue decoupling mechanism in August 2012, requesting recovery of $17 million from customers for the period June 2011 through April 2012.  At September 30, 2013, Consumers had a $17 million regulatory asset recorded for gas revenue decoupling for that period.

Renewable Energy Plan:  In January 2013, Consumers received a $69 million renewable energy grant for Lake Winds® Energy Park, which began operations in November 2012.  The grant was received from the U.S. Department of Treasury under Section 1603 of the American Recovery and Reinvestment Tax Act of 2009.

As reflected in Consumers’ 2011 biennial renewable energy plan, which the MPSC approved in 2012, this grant reduces Consumers’ cost of complying with the renewable standards prescribed by the 2008 Energy Law and, accordingly, reduces the overall renewable energy surcharge to be collected from customers.  At September 30, 2013, Consumers had a $68million regulatory liability recorded for the grant.  The regulatory liability will be amortized over the life of Lake Winds® Energy Park.

In May 2013, Consumers filed a revised renewable energy plan that reduced the size and cost of the Cross Winds® Energy Park.  In June2013, the MPSC issued an order approving Consumers’ 2011 renewable cost reconciliation filing.  In July2013, Consumers filed its 2012 renewable cost reconciliation and annual report.

Energy Optimization Plan:In May 2013, Consumers filed its fourth annual report and reconciliation for its energy optimization plan, requesting approval of its energy optimization plan costs for 2012.  In October  2013, Consumers filed a settlement agreement, which, if approved, would authorize Consumers to collect $17 million from customers during 2014 as an incentive payment for exceeding statutory targets under both its gas and electric energy optimization plans during 2012.  In August 2013, Consumers filed its energy optimization plan for the period 2014 through 2017 with the MPSC.

Consumers Gas Utility

Gas Revenue Decoupling Mechanism:The MPSC’s 2009 order in Consumers’ gas rate case authorized Consumers to implement a gas revenue decoupling mechanism.  This mechanism, which the MPSC extended through April 2012 in its 2010 order in Consumers’ gas rate case, allowed Consumers to adjust future gas rates to the degree that actual average weather-adjusted sales per customer differed from the rate order.  This mechanism was not affected by a separate Michigan Court of Appeals decision on electric revenue decoupling.

In December 2012, the MPSC approved Consumers’ reconciliation of the gas revenue decoupling mechanism for the period June 2010 through May 2011 and authorized recovery of $16 million over a three-month period that began in February 2013.  Due to high customer deliveries during this three-month period, Consumers collected more than the amount authorized and refunded the over-collection in August 2013.  In January 2013, ABATE filed an appeal with the Michigan Court of Appeals to dispute the MPSC’s conclusion that Consumers is eligible to recover the portion of the authorized recovery amount allocated to transport customers.

Consumers filed its final reconciliation of the gas revenue decoupling mechanism in August 2012, requesting recovery of $17 million from customers for the period June 2011 through April 2012.  At September 30, 2013, Consumers had a $17 million regulatory asset recorded for gas revenue decoupling for that period.

Contingencies And Commitments

2:CONTINGENCIES AND COMMITMENTS

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

CMS Energy Contingencies

Gas Index Price Reporting Investigation:  In 2002, CMS Energy notified appropriate regulatory and governmental agencies that some employees at CMS MST and CMS Field Services appeared to have provided inaccurate information regarding natural gas trades to various energy industry publications which compile and report index prices.  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, have been named as defendants in various lawsuits arising as a result of alleged inaccurate natural gas price reporting to publications that report trade information.  Allegations include manipulation of NYMEX natural gas futures and options prices, price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices in Kansas, Missouri, and Wisconsin.  The following provides more detail on the cases in which CMS Energy affiliates remain as parties:

· In 2005, CMS Energy, CMS MST, and CMS Field Services were named as defendants in a putative class action filed in Kansas state court, Learjet, Inc., et al. v. Oneok, Inc., et al.  The complaint alleges that 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 are seeking statutory full consideration damages consisting of the full consideration paid by plaintiffs for natural gas allegedly purchased from defendants.

· In 2007, a class action complaint, Heartland Regional Medical Center, et al. v. Oneok, Inc. et al., was filed as a putative class action 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 reporting activities.  Plaintiffs are seeking full consideration damages and treble 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.

· Another class action complaint, Newpage Wisconsin System v. CMS ERM, et al., was filed in 2009 in circuit court in Wood County, Wisconsin, against CMS Energy, CMS ERM, Cantera Gas Company, and others.  The plaintiff is seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees.

· In 2005, J.P. Morgan Trust Company, in its capacity as Trustee of the FLI Liquidating Trust, filed an action in Kansas state court against CMS Energy, CMS MST, CMS Field Services, and others.  The complaint alleges various claims under the Kansas Restraint of Trade Act.  The plaintiff is seeking statutory full consideration damages for its purchases of natural gas in 2000 and 2001.

After removal to federal court, all of the cases described above were transferred to the MDL.  In 2010, CMS Energy and Cantera Gas Company were dismissed from the Newpage case.  In 2011, all claims against remaining CMS Energy defendants in the MDL cases were dismissed based on FERC preemption.  Plaintiffs filed appeals in all of the cases.  The issues on appeal were whether the district court erred in dismissing the cases based on FERC preemption and denying the plaintiffs’ motions for leave to amend their complaints to add a federal Sherman Act antitrust claim.  The plaintiffs did not appeal the dismissal of CMS Energy as a defendant in these cases, but other CMS Energy entities remain as defendants.

In April2013, the U.S. Court of Appeals for the Ninth Circuit reversed the MDL decision and remanded the case to the MDL judge for further proceedings. The appellate court found that FERC preemption does not apply under the facts of these cases. The Court affirmed the MDL court’s denial of leave to amend to add federal antitrust claims.

In August 2013, the joint defense group in these cases, of which CMS Energy defendants are members, filed a petition with the U.S. Supreme Court in an attempt to overturn the decision of the U.S. Court of Appeals for the Ninth Circuit.  Plaintiffs’ responses to the petition are due in late October 2013.

These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions.  Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s possible loss would be based on widely varying models previously untested in this context.  If the outcome after appeals is unfavorable, these cases could have a material adverse impact on CMS Energy’s liquidity, financial condition, and results of operations.

Bay Harbor:  CMS Energy retained environmental remediation obligations for the collection and treatment of leachate, a liquid consisting of water and other substances, at Bay Harbor after selling its interests in the development in 2002.  Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site.  In 2012, CMS Energy and the MDEQ finalized an agreement that established the final remedies and the future release criteria at the site.  CMS Energy is in the process of completing all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit issued in 2010.  This permit requires renewal every five years.

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 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 under Superfund of the EPA’s response costs incurred at the Bay Harbor site.  CMS Land has communicated to the EPA that it does not believe that this is a valid claim.

CMS Energy has recorded a cumulative charge related to Bay Harbor of $228 million, which includes accretion expense.  At September 30, 2013, CMS Energy had a recorded liability of $55 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.  The undiscounted amount of the remaining obligation is $73 million.  CMS Energy expects to pay $12 million in 2013, $4 million in each of 2014, 2015,  2016, and 2017, 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:

· a significant increase in the cost of 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;

· the nature and extent of contamination;

· delays in the receipt of requested permits;

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

· unanticipated difficulties in meeting the technical commitments in the agreement with the MDEQ;

· 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 January 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea.  The government of Equatorial Guinea claims that CMS Energy owes $142 million in taxes, plus penalties and interest, in connection with the sale.  CMS Energy has concluded that the government’s tax claim is without merit.  The government of Equatorial Guinea indicated through a request for arbitration in October 2011 that it still intends to pursue its claim.  CMS Energy is vigorously contesting the claim, and cannot predict the financial impact or outcome of this matter.

Consumers Electric Utility Contingencies

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

Cleanup and Solid Waste:  Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA.  Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome.  Consumers estimates that its liability for NREPA sites will be between $4 million and $6 million.  At September 30, 2013, Consumers had a recorded liability of $4 million, the minimum amount in the range of its estimated probable NREPA liability.

Consumers is a potentially responsible party at a number of contaminated sites administered under Superfund.  Superfund liability is joint and several.  In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River Superfund site.  The notification claimed that the EPA has reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site.  In April 2011, Consumers received a follow‑up letter from the EPA requesting that Consumersagree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River.  All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability.  In August 2011, the EPA announced that it would proceed with the removal action plan and would continue to pursue potentially responsible parties to perform or pay for some or all of the work.  Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river.

Based on its experience, Consumers estimates that its share of the total liability for other known Superfund sites will be between $2 million and $8 million.  Various factors, including the number of potentially responsible parties involved with each site, affect Consumers’ share of the total liability.  At September 30, 2013, Consumers had a recorded liability of $2 million for its share of the total liability at these sites, the minimum amount in the range of its estimated probable Superfund liability.

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

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

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

Consumers is engaged in discussions with the EPA on all of these matters.  Depending upon the outcome of these discussions, the EPA could bring legal action against Consumers and/or Consumers could be required to install additional pollution control equipment at some or all of its coal-fueled electric generating plants, surrender emission allowances, engage in Environmental Mitigation 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.  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, but cannot reasonably estimate the extent of cost recovery.  Although Consumers cannot predict the financial impact or outcome of the entirety of these discussions, it does not expect any future loss from civil penalties and/or Environmental Mitigation Projects to be material.

Nuclear Matters:  The matters discussed in this section relate to Consumers’ previously owned nuclear generating plants.  Consumers no longer owns or operates any nuclear generating facilities.

Consumers filed a complaint in 2002 for damages resulting from the DOE’s failure to accept spent nuclear fuel from Palisades and Big Rock.  In 2011, Consumers entered into an agreement with the DOE to settle its claims for $120 million.  As part of this agreement, Consumers also settled its liability to the DOE to fund the disposal of spent nuclear fuel used at Palisades and Big Rock before 1983.  In December 2012, the MPSC issued an order establishing the regulatory treatment of the settlement amount.  In this order, the MPSC also relieved Consumers of its obligation to establish an independent trust fund for the amount that was payable to the DOE prior to the settlement.  In March 2013, a party in this case filed an appeal with the Michigan Court of Appeals to dispute the December 2012 MPSC order.  For further information, see Note 1, Regulatory Matters.

Renewable Energy Matters:  In April 2013, a group of landowners filed a lawsuit alleging, among other things, personal injury and loss of property value and land use as a result of the operations of Lake Winds® Energy Park.  Consumers cannot predict the ultimate financial impact or outcome of this matter.

Gas Environmental Matters:Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA.  These sites include 23 former MGP facilities.  Consumers operated the facilities on these sites for some part of their operating lives.  For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site.

At September 30, 2013, Consumers had a recorded liability of $121 million for its remaining obligations for these sites.  This amount represents the present value of long-term projected costs, using a discount rate of 2.57 percent and an inflation rate of 2.5 percent.  The undiscounted amount of the remaining obligation is $131 million.  Consumers expects to incur remediation and other response activity costs in 2013 and in each of the next four years as follows:

In Millions
	2013			2014			2015			2016			2017
Consumers
Remediation and other response activity costs		$	8		$	8		$	12		$	12		$	9

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.

Pursuant to orders issued by the MPSC, Consumers defers its MGP-related remediation costs and recovers them from its customers over a ten-year period.  At September 30, 2013, Consumers had a regulatory asset of $150 million related to the MGP sites.

Consumers Other Contingencies

Other Environmental Matters:  Consumers initiated preliminary investigations during 2012 at a number of potentially contaminated sites it presently owns with the intention of determining whether any contamination exists and the extent of any identified contamination.  The sites being investigated include combustion turbine sites, generating sites, compressor stations, and above-ground fuel storage tanks.  Consumers will continue its preliminary investigations at potentially contaminated sites through 2013.  Consumers cannot predict an outcome at this stage of the investigations.

Guarantees

Presented in the following table are CMS Energy’s and Consumers’ guarantees at September 30, 2013:

In Millions
			Maximum				Carrying
Guarantee Description	Issue Date	Expiration Date	Obligation				Amount
CMS Energy, including Consumers
Indemnity obligations from asset sales    and other agreements	Various	Various through September 2029		$	476	1		$	16
Guarantees	Various	Various through March 2021			57				-
Consumers
Indemnity obligations and other guarantees	Various	Various through September 2029		$	30			$	1

¹ The majority of this amount arises from stock and asset sale agreements under which CMS Energy or a subsidiary of CMS Energy, other than Consumers, indemnified the purchaser for losses resulting from various matters, including claims related to tax disputes, claims related to power purchase agreements, and defects in title to the assets or stock sold to the purchaser by CMS Energy subsidiaries.  Except for items described elsewhere in this Note, CMS Energy believes the likelihood of material loss to be remote for the indemnity obligations not recorded as liabilities.

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

Guarantee Description	How Guarantee Arose	Events That Would Require Performance
CMS Energy, including Consumers
Indemnity obligations from asset	Stock and asset sale	Findings of misrepresentation,
sales and other agreements	agreements	breach of warranties, tax claims, and
		other specific events or
		circumstances
Guarantees	Normal operating	Nonperformance or non-payment by a
	activity	subsidiary under a related contract
Consumers
Indemnity obligations and	Normal operating	Nonperformance or claims made by a third
other guarantees	activity	party under a related contract

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

Other Contingencies

Other:  In addition to the matters disclosed in this Note and Note 1, 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.

Contingencies And Commitments

2:CONTINGENCIES AND COMMITMENTS

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

CMS Energy Contingencies

Gas Index Price Reporting Investigation:  In 2002, CMS Energy notified appropriate regulatory and governmental agencies that some employees at CMS MST and CMS Field Services appeared to have provided inaccurate information regarding natural gas trades to various energy industry publications which compile and report index prices.  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, have been named as defendants in various lawsuits arising as a result of alleged inaccurate natural gas price reporting to publications that report trade information.  Allegations include manipulation of NYMEX natural gas futures and options prices, price-fixing conspiracies, restraint of trade, and artificial inflation of natural gas retail prices in Kansas, Missouri, and Wisconsin.  The following provides more detail on the cases in which CMS Energy affiliates remain as parties:

· In 2005, CMS Energy, CMS MST, and CMS Field Services were named as defendants in a putative class action filed in Kansas state court, Learjet, Inc., et al. v. Oneok, Inc., et al.  The complaint alleges that 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 are seeking statutory full consideration damages consisting of the full consideration paid by plaintiffs for natural gas allegedly purchased from defendants.

· In 2007, a class action complaint, Heartland Regional Medical Center, et al. v. Oneok, Inc. et al., was filed as a putative class action 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 reporting activities.  Plaintiffs are seeking full consideration damages and treble 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.

· Another class action complaint, Newpage Wisconsin System v. CMS ERM, et al., was filed in 2009 in circuit court in Wood County, Wisconsin, against CMS Energy, CMS ERM, Cantera Gas Company, and others.  The plaintiff is seeking full consideration damages, treble damages, costs, interest, and attorneys’ fees.

· In 2005, J.P. Morgan Trust Company, in its capacity as Trustee of the FLI Liquidating Trust, filed an action in Kansas state court against CMS Energy, CMS MST, CMS Field Services, and others.  The complaint alleges various claims under the Kansas Restraint of Trade Act.  The plaintiff is seeking statutory full consideration damages for its purchases of natural gas in 2000 and 2001.

After removal to federal court, all of the cases described above were transferred to the MDL.  In 2010, CMS Energy and Cantera Gas Company were dismissed from the Newpage case.  In 2011, all claims against remaining CMS Energy defendants in the MDL cases were dismissed based on FERC preemption.  Plaintiffs filed appeals in all of the cases.  The issues on appeal were whether the district court erred in dismissing the cases based on FERC preemption and denying the plaintiffs’ motions for leave to amend their complaints to add a federal Sherman Act antitrust claim.  The plaintiffs did not appeal the dismissal of CMS Energy as a defendant in these cases, but other CMS Energy entities remain as defendants.

In April2013, the U.S. Court of Appeals for the Ninth Circuit reversed the MDL decision and remanded the case to the MDL judge for further proceedings. The appellate court found that FERC preemption does not apply under the facts of these cases. The Court affirmed the MDL court’s denial of leave to amend to add federal antitrust claims.

In August 2013, the joint defense group in these cases, of which CMS Energy defendants are members, filed a petition with the U.S. Supreme Court in an attempt to overturn the decision of the U.S. Court of Appeals for the Ninth Circuit.  Plaintiffs’ responses to the petition are due in late October 2013.

These cases involve complex facts, a large number of similarly situated defendants with different factual positions, and multiple jurisdictions.  Presently, any estimate of liability would be highly speculative; the amount of CMS Energy’s possible loss would be based on widely varying models previously untested in this context.  If the outcome after appeals is unfavorable, these cases could have a material adverse impact on CMS Energy’s liquidity, financial condition, and results of operations.

Bay Harbor:  CMS Energy retained environmental remediation obligations for the collection and treatment of leachate, a liquid consisting of water and other substances, at Bay Harbor after selling its interests in the development in 2002.  Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site.  In 2012, CMS Energy and the MDEQ finalized an agreement that established the final remedies and the future release criteria at the site.  CMS Energy is in the process of completing all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit issued in 2010.  This permit requires renewal every five years.

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 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 under Superfund of the EPA’s response costs incurred at the Bay Harbor site.  CMS Land has communicated to the EPA that it does not believe that this is a valid claim.

CMS Energy has recorded a cumulative charge related to Bay Harbor of $228 million, which includes accretion expense.  At September 30, 2013, CMS Energy had a recorded liability of $55 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.  The undiscounted amount of the remaining obligation is $73 million.  CMS Energy expects to pay $12 million in 2013, $4 million in each of 2014, 2015,  2016, and 2017, 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:

· a significant increase in the cost of 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;

· the nature and extent of contamination;

· delays in the receipt of requested permits;

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

· unanticipated difficulties in meeting the technical commitments in the agreement with the MDEQ;

· 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 January 2002, CMS Energy sold its oil, gas, and methanol investments in Equatorial Guinea.  The government of Equatorial Guinea claims that CMS Energy owes $142 million in taxes, plus penalties and interest, in connection with the sale.  CMS Energy has concluded that the government’s tax claim is without merit.  The government of Equatorial Guinea indicated through a request for arbitration in October 2011 that it still intends to pursue its claim.  CMS Energy is vigorously contesting the claim, and cannot predict the financial impact or outcome of this matter.

Consumers Electric Utility Contingencies

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

Cleanup and Solid Waste:  Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA.  Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome.  Consumers estimates that its liability for NREPA sites will be between $4 million and $6 million.  At September 30, 2013, Consumers had a recorded liability of $4 million, the minimum amount in the range of its estimated probable NREPA liability.

Consumers is a potentially responsible party at a number of contaminated sites administered under Superfund.  Superfund liability is joint and several.  In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River Superfund site.  The notification claimed that the EPA has reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site.  In April 2011, Consumers received a follow‑up letter from the EPA requesting that Consumersagree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River.  All parties, including Consumers, that were asked to participate in the removal action plan declined to accept liability.  In August 2011, the EPA announced that it would proceed with the removal action plan and would continue to pursue potentially responsible parties to perform or pay for some or all of the work.  Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river.

Based on its experience, Consumers estimates that its share of the total liability for other known Superfund sites will be between $2 million and $8 million.  Various factors, including the number of potentially responsible parties involved with each site, affect Consumers’ share of the total liability.  At September 30, 2013, Consumers had a recorded liability of $2 million for its share of the total liability at these sites, the minimum amount in the range of its estimated probable Superfund liability.

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

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

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

Consumers is engaged in discussions with the EPA on all of these matters.  Depending upon the outcome of these discussions, the EPA could bring legal action against Consumers and/or Consumers could be required to install additional pollution control equipment at some or all of its coal-fueled electric generating plants, surrender emission allowances, engage in Environmental Mitigation 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.  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, but cannot reasonably estimate the extent of cost recovery.  Although Consumers cannot predict the financial impact or outcome of the entirety of these discussions, it does not expect any future loss from civil penalties and/or Environmental Mitigation Projects to be material.

Nuclear Matters:  The matters discussed in this section relate to Consumers’ previously owned nuclear generating plants.  Consumers no longer owns or operates any nuclear generating facilities.

Consumers filed a complaint in 2002 for damages resulting from the DOE’s failure to accept spent nuclear fuel from Palisades and Big Rock.  In 2011, Consumers entered into an agreement with the DOE to settle its claims for $120 million.  As part of this agreement, Consumers also settled its liability to the DOE to fund the disposal of spent nuclear fuel used at Palisades and Big Rock before 1983.  In December 2012, the MPSC issued an order establishing the regulatory treatment of the settlement amount.  In this order, the MPSC also relieved Consumers of its obligation to establish an independent trust fund for the amount that was payable to the DOE prior to the settlement.  In March 2013, a party in this case filed an appeal with the Michigan Court of Appeals to dispute the December 2012 MPSC order.  For further information, see Note 1, Regulatory Matters.

Renewable Energy Matters:  In April 2013, a group of landowners filed a lawsuit alleging, among other things, personal injury and loss of property value and land use as a result of the operations of Lake Winds® Energy Park.  Consumers cannot predict the ultimate financial impact or outcome of this matter.

Consumers Gas Utility Contingencies

Gas Environmental Matters:Consumers expects to incur remediation and other response activity costs at a number of sites under the NREPA.  These sites include 23 former MGP facilities.  Consumers operated the facilities on these sites for some part of their operating lives.  For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site.

At September 30, 2013, Consumers had a recorded liability of $121 million for its remaining obligations for these sites.  This amount represents the present value of long-term projected costs, using a discount rate of 2.57 percent and an inflation rate of 2.5 percent.  The undiscounted amount of the remaining obligation is $131 million.  Consumers expects to incur remediation and other response activity costs in 2013 and in each of the next four years as follows:

In Millions
	2013			2014			2015			2016			2017
Consumers
Remediation and other response activity costs		$	8		$	8		$	12		$	12		$	9

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.

Pursuant to orders issued by the MPSC, Consumers defers its MGP-related remediation costs and recovers them from its customers over a ten-year period.  At September 30, 2013, Consumers had a regulatory asset of $150 million related to the MGP sites.

Consumers Other Contingencies

Other Environmental Matters:  Consumers initiated preliminary investigations during 2012 at a number of potentially contaminated sites it presently owns with the intention of determining whether any contamination exists and the extent of any identified contamination.  The sites being investigated include combustion turbine sites, generating sites, compressor stations, and above-ground fuel storage tanks.  Consumers will continue its preliminary investigations at potentially contaminated sites through 2013.  Consumers cannot predict an outcome at this stage of the investigations.

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

Other:  In addition to the matters disclosed in this Note and Note 1, 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.

Presented in the following table are the carrying amounts and fair values, by level within the fair value hierarchy, of CMS Energy’s and Consumers’ financial instruments that are not recorded at fair value.  The table does not include information on cash, cash equivalents, short-term accounts and notes receivable, short-term investments, and current liabilities since the carrying amounts of these items approximate their fair values because of their short-term nature.  For information about assets and liabilities recorded at fair value and for additional details regarding the fair value hierarchy, see Note 4, Fair Value Measurements.

¹ Includes current portion of notes receivable of $58 million at September 30, 2013 and $40 million at December 31, 2012.

² Includes current portion of long-term debt of $511 million at September 30, 2013 and $519 million at December 31, 2012.

³ Includes current portion of long-term debt of $42 million at September 30, 2013 and $41 million at December 31, 2012.

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. 

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 and models may be used that rely on assumptions that cannot be observed or confirmed through market transactions.  CMS Energy includes the value of the conversion features in estimating the fair value of its convertible debt, and incorporates, as appropriate, information on the market prices of CMS Energy common stock. 

The effects of third-party credit enhancements are excluded from the fair value measurements of long-term debt.  At September 30, 2013 and December 31, 2012, 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. 

Presented in the following table are CMS Energy’s and Consumers’ investment securities classified as available for sale or held to maturity:

Consumers recognized gains of $4 million in January 2013 and $5 million in January 2012 from transferring shares of CMS Energy common stock to a related charitable foundation.  The gains reflected the excess of fair value over cost of the stock donated and were included in income.

Fair Value Measurements

4: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, and inputs derived from or corroborated by observable market data.

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

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

Assets and Liabilities Measured at Fair Value on a Recurring Basis

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

Cash Equivalents:  Cash equivalents and restricted cash equivalents consist of money market funds with daily liquidity.  Short-term debt instruments classified as cash equivalents or restricted cash equivalents on the consolidated balance sheets are not included since they are recorded at amortized cost.

Nonqualified Deferred Compensation Plan Assets and Liabilities:  The nonqualified deferred compensation plan assets consist of mutual funds, which are valued using the daily quoted NAVs that are publicly available and are the basis for transactions to buy or sell shares in each fund.  CMS Energy and Consumers value their nonqualified 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 the assets in other non‑current assets and the liabilities in other non‑current liabilities on their consolidated balance sheets.

DB SERP Assets:  CMS Energy and Consumers value their DB SERP assets using a market approach that incorporates quoted market prices.  The DB SERP cash equivalents consist of a money market fund with daily liquidity.  The DB SERP invests in mutual funds that hold primarily fixed-income instruments of varying maturities.  In order to meet their investment objectives, the funds hold investment-grade debt securities, and may invest a portion of their assets in high-yield securities, foreign debt, and derivative instruments.  CMS Energy and Consumers value these funds using the daily quoted NAVs that are publicly available and are the basis for transactions to buy or sell shares in each fund.  CMS Energy and Consumers report their DB SERP assets in other non‑current assets on their consolidated balance sheets.  For additional details about DB SERP securities, see Note 5, Financial Instruments.

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.  CMS Energy values its exchange-traded derivative contracts based on Level 1 quoted prices and values other derivatives using Level 2 inputs, including commodity forward prices and credit risk factors.  CMS Energy and Consumers have classified certain derivatives as Level 3 since the fair value measurements incorporate assumptions that cannot be observed or confirmed through market transactions.

The most significant derivatives classified as Level 3 are FTRs held by Consumers.  Consumers uses FTRs to manage price risk related to electricity transmission congestion.  An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges.  FTRs are accounted for as derivatives.  Under regulatory accounting, all changes in fair value associated with FTRs are deferred as regulatory assets or liabilities until the instruments are settled.  Due to the lack of quoted pricing information, Consumers determines the fair value of its FTRs based on Consumers’ average historical settlements.

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

The largest change in the fair values of Level3 assets and liabilities at CMS Energy and Consumers during the three and nine months ended September 30, 2013 and 2012 was attributable to the FTRs.

Effective July 1, 2013, CMS Energy and Consumers approved a change to the Medicare drug program provided through their OPEB Plan from an employer-sponsored prescription drug plan with a retiree drug subsidy to an EGWP to begin on January 1, 2015.  Also effective July 1, 2013, CMS Energy and Consumers approved certain benefit changes to the OPEB Plan, to begin on January 1, 2016.  Accordingly, CMS Energy and Consumers performed a remeasurement of the OPEB Plan as of July 1, 2013.  In addition, with the plan remeasurement, the discount rate used to measure the OPEB liability was increased from 4.4percent at December 31, 2012 to 5.1percent at July 1, 2013.  Assumptions regarding the expected long-term rate of return on plan assets and the health-care cost trend rate did not change from December 31, 2012 levels.

As a result of these changes, CMS Energy’s (including Consumers’) OPEB liability decreased by $638 million, its OPEB regulatory asset of $580 million was eliminated, and an OPEB regulatory liability of $34 million was established as of July 1, 2013.  CMS Energy’s accumulated other comprehensive loss decreased by $24 million.  CMS Energy’s (including Consumers’) OPEB cost is expected to decrease by $48 million in 2013.  Consumers’ OPEB liability decreased by $614 million, its OPEB regulatory asset of $580 million was eliminated, and an OPEB regulatory liability of $34 million was established as of July 1, 2013.  Consumers’ OPEB cost is expected to decrease by $46 million in 2013.

CMS Energy and Consumers also remeasured certain deferred tax assets as a result of the approved change to the Medicare drug program.  Effective January 2015, CMS Energy and Consumers will no longer receive Medicare Part D drug subsidies.  Accordingly, CMS Energy (including Consumers) decreased its deferred tax assets by $148 million, reduced its regulatory income tax liabilities by $144 million, and increased its income tax expense by $4 million.  Consumers decreased its deferred tax assets by $144 million, and reduced its regulatory income tax liabilities by an equal amount.

² Obligations under this facility are secured by FMBs of Consumers.

Short-term Borrowings:  Under Consumers’ revolving accounts receivable sales program, Consumers may transfer up to $250 million of accounts receivable, subject to certain eligibility requirements.  These transactions are accounted for as short-term secured borrowings.  At September 30, 2013, $250 million of accounts receivable were eligible for transfer.  During the nine months ended September 30, 2013, Consumers’ average short-term borrowings totaled $7 million, with a weighted-average annual interest rate of 0.94 percent.

Contingently Convertible Securities:  Presented in the following table are the significant terms of CMS Energy’s contingently convertible securities at September 30, 2013:

During 20 of the last 30 trading days ended September 30, 2013, the adjusted trigger-price contingencies were met for the contingently convertible senior notes, and as a result, the senior notes are convertible at the option of the note holders for the three months ending December 31, 2013.  The senior notes, if converted, require CMS Energy to pay cash up to the principal amount of the securities.  Any conversion value in excess of the principal amount can be paid in cash or in shares of CMS Energy’s common stock, at the election of CMS Energy.

For the nine months ended September 30, 2013, CMS Energy received $300 million of common stock dividends from Consumers.

Notes Receivable [Abstract]

Allowance For Loan Losses Policy

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

EnerBank notes receivable are unsecured consumer installment loans for financing home improvements.

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

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