COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies (EME and Midwest Generation, except as noted)

Chapter 11 Cases

~~EME~~In ~~and~~order ~~Midwest Generation continue~~ to ~~experience~~preserve operating losses due to low realized energy and capacity prices, high fuel costs, and low generation at the Midwest Generation plants. These operating losses are a continuation of trends initially experienced in the fourth quarter of 2011. These adverse trends coupled with pending debt maturities and the need to retrofit the Midwest Generation plants to comply with governmental regulations were expected to exhaust EME's and Midwest Generation's liquidity~~. Consequently~~, on December 17, 2012, EME and 16 of its wholly owned subsidiaries, Camino Energy Company, Chestnut Ridge Energy Company, Edison Mission Energy Fuel Services, LLC, Edison Mission Fuel Resources, Inc., Edison Mission Fuel Transportation, Inc., Edison Mission Holdings Co., Edison Mission Midwest Holdings Co., Midwest Finance Corp., Midwest Generation EME, LLC, Midwest Generation, Midwest Generation Procurement Services, LLC, Midwest Peaker Holdings, Inc., Mission Energy Westside, Inc., San Joaquin Energy Company, Southern Sierra Energy Company, and Western Sierra Energy Company (the Initial Debtors) filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code. On May 2, 2013, 3 additional EME subsidiaries, EME Homer City Generation L.P. (Homer City), Homer City Property Holdings Inc., and Edison Mission Finance Company (collectively, the ~~Debtor~~Homer ~~Entities~~City Debtors) filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code. The Initial Debtors' chapter 11 cases and the Homer City Debtors' chapter 11 cases (collectively, the Chapter 11 Cases) ofare being jointly administered under case No. 12-49219 (JPC). The Initial Debtors and the ~~Bankruptcy~~Homer ~~Code~~City Debtors are collectively referred to as the Debtor Entities.

The Debtor Entities remain in possession of their property and continue their business operations uninterrupted as "debtors-in-possession" under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. Other than the Debtor Entities, none of EME's other direct or indirect subsidiaries is a debtor in the Chapter 11 Cases. The filing of the Chapter 11 Cases automatically stayed most actions against the Debtor Entities, including actions to enforce the payment of EME's $3.7 billion of unsecured senior notes and Midwest Generation's obligations related to leases of the Powerton Station and Units 7 and 8 of the Joliet Station (the Powerton and Joliet Sale Leaseback). Absent an order from the Bankruptcy Court, substantially all of the Debtor Entities' pre-petition liabilities are subject to settlement under a reorganization plan.

The ~~filing~~factors ofthat ~~the~~caused ~~Chapter 11~~EME ~~Cases~~and ~~automatically~~Midwest ~~stayed~~Generation ~~most~~to ~~actions~~seek ~~against~~relief ~~the~~under ~~Debtor~~Chapter ~~Entities~~11, including ~~actions~~low torealized ~~enforce~~energy ~~the~~and ~~payment~~capacity ofprices, ~~EME's~~high ~~$3.7 billion~~fuel ofcosts ~~unsecured~~and ~~senior~~low ~~notes~~generation, ~~and~~combined with capital requirements associated with retrofitting the Midwest Generation's ~~obligations~~plants ~~related~~to comply with governmental regulations continue to ~~leases~~exist. ofAs ~~the~~a ~~Powerton~~result ~~Station~~of these factors and ~~Units~~based 7on ~~and~~further 8analysis of ~~the~~its ~~Joliet~~capital ~~Station~~allocation ~~(the~~strategy, ~~Powerton~~EME and ~~Joliet~~Midwest ~~Sale~~Generation ~~Leaseback).~~recorded ~~Absent~~ an ~~order~~impairment ~~from~~charge ~~the~~of ~~Bankruptcy~~$464 million ~~Court~~related to its Will County Station.

~~Basis~~The filing of ~~Presentation~~the Chapter 11 Cases constitutes an event of default under the Powerton and Joliet Sale Leaseback and under instruments governing the Senior Lease Obligation Bonds issued to finance these leases. EME, Midwest Generation, the owner-lessors, and certain of the holders of the pass-through certificates of Midwest Generation's lessor debt (the Certificate Holders) have been engaged in ongoing discussions regarding the ultimate disposition of the leases. In June 2013, EME and Midwest Generation agreed, among other things, to make monthly rental payments of $3.75 million beginning in July 2013 and to pay certain professional fees for the owner-lessors and Certificate Holders in exchange for an extension of the deadline to assume or reject the Powerton and Joliet leases and the agreement of the Certificate Holders to forbear and to direct the lease indenture trustee and pass-through trustee to forbear from seeking payment of any administrative claim for rent under the Powerton and Joliet leases (except the monthly partial rental payments of $3.75 million under the agreement) before the earlier of the effective date of a chapter 11 plan for Midwest Generation or a sale of substantially all of the assets of Midwest Generation. The parties filed a motion detailing the terms of this agreement and the Bankruptcy Court approved the extension

On October 18, 2013, EME and its debtor subsidiaries, including Midwest Generation, entered into various agreements that, upon completion, would ultimately implement a reorganization of the Debtor Entities through a sale of substantially all of EME’s assets, including its equity interests in substantially all of its debtor and non-debtor subsidiaries, to a wholly owned subsidiary of NRG Energy Inc., upon Bankruptcy Court confirmation and consummation of a plan of reorganization (the NRG Sale). Midwest Generation is included in the equity interests to be sold. For additional information, see Note 15—Restructuring Activities—NRG Sale.

The accompanying consolidated financial statements have been prepared assuming that EME and Midwest Generation will continue as going concerns. Financial statements prepared on this basis assume the realization of assets and the satisfaction of liabilities in the normal course of business for the 12-month period following the date of the financial statements. The accompanying consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classification of liabilities or any other adjustments that might be necessary if EME and Midwest Generation were unable to continue as going concerns.

Basis of Presentation

There are no material updates to EME's and Midwest Generation's significant accounting policies since the filing of EME's and Midwest Generation's combined annual report on Form 10-K for the year ended December 31, 2012, with the exception of new accounting principles adopted as discussed below in "—New Accounting Guidance." This quarterly report should be read in conjunction with the financial statements and notes included in EME's and Midwest Generation's combined annual report on Form 10-K for the year ended December 31, 2012.

In the opinion of management, all adjustments, consisting of recurring accruals, have been made that are necessary to fairly state the consolidated financial position and results of operations and cash flows in accordance with accounting principles generally accepted in the United States of America (GAAP) for the periods covered by this quarterly report on Form 10-Q. The results of operations for the three- and nine-month periods ended September 30, 2013 are not necessarily indicative of the operating results for the full year. Except as indicated, amounts reflected in the notes to the consolidated financial statements relate to continuing operations of EME and Midwest Generation. Certain prior period amounts have been reclassified to conform to the current year financial statement presentation pertaining to discontinued operations. In December 2012, EME reclassified costs previously presented as professional fees related to potential reorganization to reorganization items, net to reflect the proper classification of costs that were directly associated with the Chapter 11 Cases but were incurred prior to the December 17, 2012 petition date. Accordingly, EME's consolidated statements of operations for the three and nine months ended September 30, 2012 were revised to reflect $7 million and $9 million, respectively, of professional fees related to potential reorganization as reorganization items, net. Management believes the reclassification does not have a material impact on the prior year financial statements as it has no impact on loss from continuing operations or net loss.

Cash Equivalents

Cash equivalents included money market funds totaling $~~862~~948 million and $615 million for EME and $~~111~~103 million and $75 million for Midwest Generation at ~~March~~September 3130, 2013 and December 31, 2012, respectively. The carrying value of cash equivalents equals the fair value as all investments have original maturities of less than three months.

New Accounting Guidance

Accounting Guidance Adopted in 2013

Offsetting Assets and Liabilities

In December 2011 and December 2012, the Financial Accounting Standards Board (FASB) issued accounting standards updates modifying the disclosure requirements about the nature of an entity's rights of offsetting assets and liabilities in the consolidated balance sheet under master netting agreements and related arrangements associated with financial and derivative instruments. The guidance requires increased disclosure of the gross and net recognized assets and liabilities, collateral positions, and narrative descriptions of setoff rights. EME and Midwest Generation adopted this guidance effective January 1, 2013.

positions, and narrative descriptions of setoff rights. EME and Midwest Generation adopted this guidance effective January 1, 2013.

Presentation of Items Reclassified out of Accumulated Other Comprehensive Income

In February 2013, the FASB issued an accounting standards update which requires disclosure related to items reclassified out of accumulated other comprehensive income (AOCI). The guidance requires entities to present separately, for each component of other comprehensive income (OCI), current period reclassifications and the remainder of the current-period OCI. In addition, for certain current period reclassifications, an entity is required to disclose the effect of the item reclassified out of AOCI on the respective line item of net income. EME adopted this guidance effective January 1, 2013.

In February 2013, the FASB issued an accounting standard update which modifies the requirements for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The guidance requires companies to measure these obligations as the sum of the amount the company has agreed with co-obligors to pay and any additional amount it expects to pay on behalf of one or more co-obligors. This guidance is effective for fiscal years beginning after December 31, 2013. EME and Midwest Generation do not expect this guidance to have a material impact on results of operations.

Presentation of Unrecognized Tax Benefits

In July 2013, the FASB issued an accounting standard update which clarifies that a liability for an unrecognized tax benefit should be presented as a reduction of a deferred tax asset when settlement of the liability with the taxing authority results in the reduction of a net operating loss or tax credit carryforward. The requirement to record a non-cash settlement in a net manner does not affect EME and Midwest Generation's analysis of the realization of deferred tax assets. This guidance is effective for fiscal years beginning after December 31, 2013. EME and Midwest Generation do not expect this guidance to have a material impact on results of operations.

Note 3. Variable Interest Entities (EME only)

Projects or Entities that are Consolidated

At ~~March~~September 3130, 2013 and December 31, 2012, EME consolidated 16 and 15 projects, respectively, ~~with~~that have noncontrolling interests held by others. These projects have a total generating capacity of 958 megawatts (MW) and 878 MW, respectively,. ~~that~~The ~~have~~increase ~~noncontrolling~~in ~~interests~~the ~~held~~number byof ~~others.~~projects ~~Projects~~ consolidated atis ~~March 31, 2013 increased from December 31, 2012~~ due to the sale of Edison Mission Wind Inc.'s (Edison Mission Wind) indirect equity interest in the Broken Bow I wind project (80 MW in Nebraska) to Capistrano Wind Partners for $112 million. Edison Mission Wind is a wholly owned subsidiary of EME. Outside investors provided $94 million of the funding. In determining that EME was the primary beneficiary of the projects that are consolidated, key factors considered were EME's ability to direct commercial and operating activities and EME's obligation to absorb losses of the variable interest entities.

EME's summarized financial information for consolidated projects consisted of the following:

Capistrano Wind Partners

In addition to the Broken Bow I transaction discussed above, in February 2012, Edison Mission Wind sold its indirect equity interests in the Cedro Hill wind project (150 MW in Texas), the Mountain Wind Power I wind project (61 MW in Wyoming), and the Mountain Wind Power II wind project (80 MW in Wyoming) to Capistrano Wind Partners for $346 million. Outside investors provided $238 million of the funding and Mission Energy Holding Company (MEHC) made a $4 million preferred investment. In December 2012, Edison Mission Wind sold its indirect equity interest in the Crofton Bluffs wind project (40 MW in Nebraska) to Capistrano Wind Partners for $58 million. Outside investors provided $46 million of the funding.

Through their ownership of Capistrano Wind Holdings, an indirect subsidiary of EME, Edison Mission Wind and EME's parent company, MEHC, own 100% of the Class A equity interests in Capistrano Wind Partners, and the Class B preferred equity interests are held by outside investors. ~~Under~~In the ~~terms~~event ofthat ~~the~~Edison ~~formation~~Mission ~~documents,~~Wind ~~preferred~~is ~~equity~~no ~~interests~~longer ~~receive~~included ~~100%~~in of the ~~cash~~consolidated ~~available~~income ~~for~~tax ~~distribution~~returns upof toEIX, aMEHC's ~~scheduled~~equity ~~amount~~interest converts to ~~target~~common astock ~~certain~~such ~~return~~that ~~and~~Capistrano ~~thereafter~~Wind ~~cash~~Holdings ~~distributions~~would ~~are~~remain ~~shared.~~included ~~Cash~~in ~~available~~the ~~for~~EIX ~~distribution~~consolidated ~~includes~~tax ~~90%~~group.

Edison Mission Wind retains indirect beneficial ownership of the common equity in the projects, net of MEHC's preferred investment, and retains responsibilities for managing the operations of Capistrano Wind Holdings and its projects. Accordingly, EME will continue to consolidate these projects. The $378 million contributed by the third-party investors and the $4 million preferred investment made by MEHC are reflected in noncontrolling interests on EME's consolidated balance sheet at September 30, 2013. The transactions between Edison Mission Wind and Capistrano Wind Partners were accounted for as a transfer among entities under common control and, therefore, resulted in no change in the book basis of the transferred assets. However, the transaction did trigger a taxable gain and new tax basis in the assets with a corresponding adjustment to deferred taxes and a reduction to equity.

Note 4. Fair Value Measurements (EME, Midwest Generation)

Recurring Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (referred to as an "exit price"). Fair value of an asset or liability considers assumptions that market participants would use in pricing the asset or liability, including assumptions about nonperformance risk, which was not material as of ~~March~~September 3130, 2013 and December 31, 2012 for both EME and Midwest Generation.

Valuation Techniques Used to Determine Fair Value

Assets and liabilities are categorized into a three-level fair value hierarchy based on valuation inputs used to determine fair value. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The fair value of transfers in and out of each level is determined at the end of each reporting period.

Level 1

The fair value of Level 1 assets and liabilities is determined using unadjusted quoted prices in active markets that are available at the measurement date for identical assets and liabilities. This level includes exchange-traded derivatives and money market funds.

Level 2

The fair value of Level 2 assets and liabilities is determined using the income approach by obtaining quoted prices for similar assets and liabilities in active markets and inputs that are observable, either directly or indirectly, for substantially the full term of the instrument. This level includes over-the-counter derivatives and interest rate swaps.

Over-the-counter derivative contracts are valued using standard pricing models to determine the net present value of estimated future cash flows. Inputs to the pricing models include forward published or posted clearing prices from exchanges (New York Mercantile Exchange and Intercontinental Exchange) for similar instruments and discount rates. A primary price source that best represents trade activity for each market is used to develop observable forward market prices in determining the fair value of these positions. Broker quotes, prices from exchanges, or comparison to executed trades are used to validate and corroborate the primary price source. These price quotations reflect mid-market prices (average of bid and ask) and are obtained from sources believed to provide the most liquid market for the commodity.

1415

~~Table~~source that best represents trade activity for each market is used to develop observable forward market prices in determining the fair value of ~~Contents~~these positions. Broker quotes, prices from exchanges, or comparison to executed trades are used to validate and corroborate the primary price source. These price quotations reflect mid-market prices (average of bid and ask) and are obtained from sources believed to provide the most liquid market for the commodity.

Level 3

The fair value of Level 3 assets and liabilities is determined using the income approach through various models and techniques that require significant unobservable inputs. This level includes over-the-counter options and derivative contracts that trade infrequently, such as congestion revenue rights and long-term power agreements.

Assumptions are made in order to value derivative contracts in which observable inputs are not available. Changes in fair value are based on changes to forward market prices, including extrapolation of short-term observable inputs into forecasted prices for illiquid forward periods. In circumstances where fair value cannot be verified with observable market transactions, it is possible that a different valuation model could produce a materially different estimate of fair value. Modeling methodologies, inputs, and techniques are reviewed and assessed as markets continue to develop and more pricing information becomes available. The fair value is adjusted when it is concluded that a change in inputs or techniques would result in a new valuation that better reflects the fair value of those derivative contracts.

Level 3 Valuation Process

The process of determining fair value of commodity derivative contracts is the responsibility of the risk department, which reports to the chief financial officer. This department obtains observable and unobservable inputs through broker quotes, exchanges, and internal valuation techniques and uses both standard and proprietary models to determine fair value. Each reporting period, the risk and key finance departments collaborate to determine the appropriate fair value methodologies and classifications for each derivative. Inputs are validated for reasonableness by comparison against prior prices, other broker quotes, and volatility fluctuation thresholds. Inputs used and valuations are reviewed period-over-period and compared with market conditions to determine reasonableness. ~~The following table sets forth the valuation techniques and significant unobservable inputs used to determine fair value for EME's Level 3 assets and liabilities:~~

Level 3 Fair Value Sensitivity

For congestion contracts, generally, an increase (decrease) in congestion prices in the last auction relative to the contract price will increase (decrease) fair value. For power contracts, generally, an increase (decrease) in long-term forward power prices at illiquid locations relative to the contract price will increase (decrease) fair value.

Viento Funding II terminated $78 million amortizing notional amount 3.415% interest rate swap agreements and entered into several tranches of new interest rate swap agreements to hedge the majority of exposure to fluctuations in interest rates. As a result of the termination, EME wrote off $4 million of unamortized deferred financing costs as a loss on early extinguishment of debt in the consolidated statements of operations. For additional information, see Note 6—Derivative Instruments and Hedging-Interest Rate Risk Management.

Credit Facilities and Letters of Credit

At ~~March~~September 3130, 2013, letters of credit under EME's and its subsidiaries' credit facilities aggregated $~~158~~169 million and were scheduled to expire as follows: $662 million in 2013, $2157 million in 2014, $2117 million in 2017, $199 million in 2018, $1827 million in ~~2021~~2020, ~~and~~ $1318 million in ~~2022.~~2021, ~~Standby letters of credit include~~ $3013 million ~~issued~~ in ~~connection~~2022 ~~with~~and ~~the power purchase agreement with Southern California Edison Company (SCE), an affiliate of EME, under the Walnut Creek credit facility.

In April 2013, Edison Mission Wind completed a $75 million letter of credit facility which expires on April 30, 2016. Letters of credit issued under this facility are secured by cash collateral and, to the extent issued on behalf of entities that are not subsidiaries of Edison Mission Wind, by reimbursement agreements between Edison Mission Wind and those entities.

EME may seek an additional financing while it is a debtor-in-possession (DIP Financing) which would be used to enhance liquidity and working capital, and which would be subject to Bankruptcy Court approval and other conditions. There is no assurance that EME will pursue, or if pursued, complete a DIP Financing.

Big Sky Turbine Financing

In October 2009, EME's subsidiary, Big Sky Wind, LLC (Big Sky), entered into turbine financing arrangements with the turbine manufacturer Suzlon Wind Energy Corporation (Suzlon) for wind turbine purchase obligations related to the 240 MW Big Sky wind project. The loan associated with the financing arrangements has a five-year final maturity. However, the satisfaction of certain criteria, including project performance and absence of serial defects, may trigger earlier repayment. In September 2012, Suzlon sued Big Sky in New York federal court seeking a declaratory judgment that the early repayment ~~triggers~~provisions had been satisfied ~~such~~and that Big Sky ~~would~~should be ~~obligated~~required to ~~make~~repay ~~full~~the ~~early~~loan ~~repayment~~in offull ~~its loan~~ in February 2013. Big Sky answered Suzlon's complaint and denied the allegations and counterclaimed, based upon Big Sky's belief and assertion that certain defects existing in the turbine equipment supplied by Suzlon as the turbine supplier would preclude the early repayment provisions. The litigation is pending in New York federal court. The Big Sky loan is secured by a leasehold mortgage on the project's real property assets, a pledge of all other collateral of the Big Sky wind project, as well as a cash reserve account into which one-third of distributable cash flow, if any, of the Big Sky wind project is to be deposited on a monthly basis. The loan is also secured by pledges of Big Sky's direct and indirect ownership interests in the project but is nonrecourse to EME. For further details regarding consolidated assets pledged as security for debt obligations, see Note 3—Variable Interest Entities.

~~Restricted~~As ~~Net~~of ~~Assets~~September 30, 2013, $228 million was outstanding under the vendor financing loan at an effective interest rate of ~~Subsidiaries~~3.94%. EME has been in discussions with Suzlon regarding a potential sale of EME's interest in the Big Sky wind project in exchange for forgiveness of debt and other consideration. These discussions are ongoing and EME has not made any decisions with respect to a potential sale. As a result, Big Sky's long-lived assets, consisting of property, plant and equipment and deferred revenue, were evaluated for impairment under the Held for Use model of Accounting Standards Codification 360 Property, Plant, and Equipment (ASC 360). The probability weighted future undiscounted cash flows associated with this asset group exceeded its carrying value at September 30, 2013 and consequently no impairment has been recognized. If EME and Suzlon do agree upon a sale transaction under terms similar to those currently under discussion, EME would record a material loss. If EME and Suzlon do not agree upon a sale transaction, Big Sky will need to arrange alternative financing, if available, to repay the loan at maturity or reach agreement with the lender to extend the maturity date of the loan. EME does not intend to make an investment in the project and is under no obligation to do so. If a restructuring of the loan or a sale effort is unsuccessful, Suzlon may foreclose on the project resulting in a write-off of the entire investment in the project. At September 30, 2013, EME's investment in the Big Sky wind project consisted of assets of $451 million and liabilities of $369 million.

~~EME's~~Walnut subsidiaries that are not Debtor Entities were in compliance with all of their debt covenants at March 31, 2013 except for the required reserve amount at American Bituminous Power Partners, L.P. (Ambit) and the defaults related to the Viento II Financing and the High Lonesome Financing. Accordingly, the net assets of these projects are considered restricted. Restricted net assets are those that cannot be transferred to EME in the form of loans, advances, or cash dividends without the consent of third parties, typically lenders or partners. In addition, EME also has partnership agreements which require the approval of unaffiliated partners' for distributions and financing agreements which require the minimum reserve or operating account funding levels. At March 31, 2013, the restricted net assets of EME's subsidiaries was $1.8 billion.Creek

Walnut Creek, a 479 MW gas-fired peaker plant, achieved commercial operation during the second quarter 2013, and accordingly, EME completed, through two wholly owned subsidiaries, Walnut Creek Energy and WCEP Holdings, LLC, the conversion of its nonrecourse financings from construction loans to 10-year amortizing term loans. Walnut Creek started earning revenues under its long-term purchase power agreement in June 2013.

Note 6. Derivative Instruments and Hedging Activities (EME, Midwest Generation)

EME and Midwest Generation use derivative instruments to reduce their exposure to market risks that arise from price fluctuations of electricity, capacity, fuel, emission allowances, transmission rights, and interest rates. The derivative financial instruments vary in duration, ranging from a few days to several years, depending upon the instrument. To the extent that EME and Midwest Generation do not use derivative instruments to hedge these market risks, the unhedged portions will be subject to the risks and benefits of spot market price movements.

Risk management positions may be designated as cash flow hedges or economic hedges, which are derivatives that are not designated as cash flow hedges. Economic hedges are accounted for at fair value on EME's and Midwest Generation's consolidated balance sheets as derivative assets or liabilities with offsetting changes recorded on the consolidated statements of operations. For derivative instruments that qualify for hedge accounting treatment, the fair value is recognized on EME's and Midwest Generation's consolidated balance sheets as derivative assets or liabilities with offsetting changes in fair value, to the extent effective, recognized in AOCI until reclassified into earnings when the related forecasted transaction occurs. The portion of a cash flow hedge that does not offset the change in the fair value of the transaction being hedged, which is commonly referred to as the ineffective portion, is immediately recognized in earnings. The results of derivative activities are recorded in cash flows from operating activities on the consolidated statements of cash flows.

Derivative instruments that are utilized by EME for trading purposes are measured at fair value and included on the consolidated balance sheets as derivative assets or liabilities, with offsetting changes recognized in operating revenues on the consolidated statements of operations.

Where EME's and Midwest Generation's derivative instruments are subject to a master netting agreement or contain collateral deposit requirements and the criteria of authoritative guidance are met, EME presents its derivative assets and liabilities on a net basis on its consolidated balance sheets. EME's and Midwest Generation's master netting agreements allow for the right of offset for contracts with physical settlement. They do not allow for cross commodity settlement unless all positions are liquidated.

Since EME's and Midwest Generation's credit ratings are below investment grade, EME and its subsidiaries have provided collateral in the form of cash and letters of credit for the benefit of derivative counterparties and brokers. The amount of margin and collateral deposits generally varies based on changes in fair value of the related positions. Future changes in power prices could expose EME and Midwest Generation to additional collateral postings.

EME's and Midwest Generation's approach to trading and risk management depends, in part, on the ability to use clearing brokers to enter into market transactions. As a result of their financial position, EME and Midwest Generation have limited access to enter into such transactions and have been subject to increased initial collateral and margin requirements. There is no assurance that EME and Midwest Generation will continue to be able to utilize clearing brokers. If EME and Midwest Generation become unable to utilize clearing brokers, they may seek to execute bilateral transactions with third parties which could be unavailable on commercially reasonable terms or at all.22

²	These positions adjust financial and physical positions, or day-ahead and real-time positions to reduce costs or increase gross margin. The net sales positions of these categories are primarily related to hedge transactions that are not designated as cash flow hedges.


³	Hedge transactions for capacity result from bilateral trades. Capacity sold in the PJM Interconnection, LLC Reliability Pricing Model (PJM RPM) auction is not accounted for as a derivative.


⁴	Congestion contracts include financial transmission rights, transmission congestion contracts, or congestion revenue rights. These positions are similar to a swap, where the buyer is entitled to receive a stream of revenues (or charges) based on the hourly day-ahead price differences between two locations.

Interest Rate Risk Management

EME mitigates the risk of interest rate fluctuations for a number of its project financings by arranging for fixed rate financing or variable rate financing with interest rate swaps, interest rate options, or other hedging mechanisms.

AsThrough July 2013, as a result of the Chapter 11 Cases and the short-term forbearance agreements that ~~have~~had been executed with the lenders and the EME subsidiary borrowers, itEME iscould no longer conclude it was probable that the future interest payments associated with the Viento II Financing ~~will~~would occur. Accordingly, the cash flow ~~hedge~~hedges associated with these interest rate swaps ~~was~~were prospectively discontinued. ~~Because~~Unrealized ~~the~~gains ~~underlying forecasted transactions remain at least reasonably possible, the fair value~~ of ~~the~~$1 ~~effective~~million ~~portion of these cash flow hedges remains in AOCI~~ and ~~will~~$6 million beduring ~~reclassified to results of operations when~~ the ~~underlying~~three ~~transactions~~and ~~occur~~nine ormonths ~~become~~ended ~~probable~~September 30, of2013, ~~not~~respectively, ~~occurring.~~were ~~EME~~ recorded ~~unrealized gains of $1 million~~ in ~~the~~interest ~~first~~expense ~~quarter of 2013 in operating revenues~~ on the consolidated statements of operations ~~representing~~from changes in the fair value of ~~discontinued~~ interest rate swaps.

Financing in July 2013, EME entered into new interest rate swaps and re-designated the existing interest rate swaps as cash flow hedges. Interest rate swap termination fees of $6 million were recorded as reduction to derivative liabilities on the consolidated balance sheets.

¹	EME's interest rate swaps are not subject to master netting agreements and do not require EME to post collateral.

EME's subsidiaries have posted $59 million and $61 million cash margin in the aggregate with various counterparties at March 31, 2013 and December 31, 2012, respectively, to support hedging and trading activities. The cash margin posted is required by counterparties as an initial collateral deposit and cannot be offset against the fair value of open contracts except in the event of default. EME's exposure is composed of $50 million and $44 million of net accounts receivable at March 31, 2013 and December 31, 2012. For positions subject to a master netting agreement, EME is in a net asset position, and in the event of default, cash collateral would be returned to EME. EME did not have any collateral received from counterparties as of March 31, 2013 and December 31, 2012.25

The cash margin posted is required by counterparties as an initial collateral deposit and cannot be offset against the fair value of open contracts except in the event of default. EME's exposure is composed of $42 million and $44 million of net accounts receivable at September 30, 2013 and December 31, 2012, respectively. For positions subject to a master netting agreement, EME is in a net asset position, and in the event of default, cash collateral would be returned to EME. EME did not have any collateral received from counterparties as of September 30, 2013 and December 31, 2012.

In total, ~~2012~~EME recorded contributions from EIX related to the tax-allocation agreements of $38 million during 2013.

Without objectively verifiable evidence supporting the taxable income forecast of the EIX consolidated tax group during 2013, EME is not currently able to determine whether it is more likely than not that future tax-sharing payments will occur. EME's deferred tax asset valuation allowance increased to $742 million at September 30, 2013 from $444 million at December 31, 2012 partially due to $167 million related to an asset impairment charge on the Will County Station recorded during the third quarter of 2013. For additional information, see Note 13—Impairment of Long-Lived Assets.

Tax Dispute

The Internal Revenue Service examination phase of tax years 2003 through 2006, which included a proposed adjustment related to EME, was completed in the fourth quarter of 2010. The proposed adjustment increases the taxable gain on the 2004 sale of EME's international assets, which if sustained, would result in a federal tax payment of approximately $~~201~~205 million, including approximately $57 million of interest and $42 million in penalties through ~~March~~September 3130, 2013 ~~(the Internal Revenue Service has asserted a 40% penalty for understatement of tax liability related to this matter)~~. EME disagrees with the proposed adjustment and filed a protest with the Internal Revenue Service in the first quarter of 2011. The appeals process to date has not resulted in a change in the proposed adjustment by the Internal Revenue Service. EME continues to seek resolution through the appeals process and has requested technical advice from the Internal Revenue Service National Office. If a deficiency notice is issued on this item, EME has 90 days to pay the tax, interest, and any penalties or to file a petition in United States Tax Court.

At December 31, 2012, $106 million of tax benefits that would have been collected by Midwest Generation in a hypothetical tax return prepared on a separate return basis but was not collectible under Midwest Generation's tax-allocation agreement were accounted for as non-cash distributions to Midwest Generation's parent. Midwest Generation's tax-allocation agreement only permits the use of net operating losses to offset future taxable income and does not include the right to receive payments.

Note 9. Commitments and Contingencies (EME and Midwest Generation, except as noted)

Lease Commitments

Powerton and Joliet Sale Leaseback

Covenants in the Powerton and Joliet Sale Leaseback documents include restrictions on the ability of EME and Midwest Generation to, among other things, incur debt, create liens on their property, merge or consolidate, sell assets, make investments, engage in transactions with affiliates, make distributions, make capital expenditures, enter into agreements restricting their ability to make distributions, engage in other lines of business, enter into swap agreements, or engage in transactions for any speculative purpose.

The filing of the Chapter 11 Cases constitutes an event of default under the Powerton and Joliet Sale Leaseback and under instruments governing the Senior Lease Obligation Bonds issued to finance these leases. Prior to the filing of the Chapter 11 Cases, EME and Midwest Generation had entered into a forbearance agreement with the owner-lessors, the owner-lessors' equity owners, and ~~certain of~~ the ~~certificate~~Certificate ~~holders~~Holders. Under the terms of the forbearance agreement, Midwest Generation did not make the scheduled lease ~~payments~~payment of $76 million on January 2, 2013, but on February 15, 2013, did pay the ratable portion of the rent due under the leases attributable to the period between December 17, 2012 and January 2, 2013 of $7 million. ~~The~~This forbearance agreement has expired. In June 2013, ~~however~~EME and Midwest Generation agreed, ~~the~~among ~~automatic~~other ~~stay~~things, ~~provisions~~to make monthly rental payments of ~~the~~$3.75 million ~~Bankruptcy~~beginning ~~Code~~in ~~and~~July 2013, in lieu of the scheduled $76 million lease ~~documents~~payment ~~prevent~~due ~~the~~on ~~owner-lessors~~July 2, ~~and~~2013.

EME ~~The~~would ~~forbearance~~retain ~~agreement~~all ~~did~~liabilities ~~not~~with ~~impact~~respect to the ~~automatic~~payment ~~stay~~of or the ~~provisions~~cure amount as set forth in the ~~lease~~Asset ~~documents~~Purchase Agreement (the Powerton and Joliet Cure Amount). The cure amount would have been approximately $150 million at September 30, 2013. For additional information, see Note 15—Restructuring Activities—NRG Sale.

Each lease sets forth a termination value payable upon certain circumstances, which generally declines over time. A default under the terms of the Powerton and Joliet leases could result in foreclosure and a loss by Midwest Generation of its lease interest in the plant. In addition, under certain circumstances, a default would trigger obligations under EME's guarantee of such leases. These events could have an adverse effect on EME's and Midwest Generation's results of operations and financial position. EME and Midwest Generation must assume the Powerton and Joliet Sale Leaseback by July 1, 2013 or else it will be automatically rejected. EME and Midwest Generation are currently analyzing these options.

27Operating Lease Commitments

~~Table~~At September 30, 2013, Midwest Generation had future minimum operating lease payments totaling approximately $4 million, which consists of ~~Contents~~$1 million for the remainder of 2013, $1 million for 2014, $1 million for 2015, and $1 million for 2016. Future minimum operating lease commitments decreased from December 31, 2012 primarily due to amended contracts and the rejection of executory contracts in connection with the Chapter 11 Cases.

Other Commitments

Fuel Supply Contracts

At September 30, 2013, Midwest Generation had commitments to purchase coal from third-party suppliers at fixed prices, subject to adjustment clauses. These commitments under existing agreements are estimated to aggregate $336 million, which consists of: $186 million for the remainder of 2013 and $150 million for 2014. Midwest Generation has the right to reject these fuel supply contracts in connection with the Chapter 11 Cases.

Capital Commitments

At ~~March~~September 3130, 2013, Midwest Generation had firm commitments ~~for~~to ~~capital~~spend ~~expenditures totaling~~ approximately $618 million, ~~which~~during ~~are expected to be incurred as follows: $16 million for~~ the remainder of 2013, and $81 million for 2014, ~~$20 million~~ for ~~2015,~~capital ~~and $17 million for 2016~~expenditures.

Other Contractual Obligations

At ~~March~~September 3130, 2013, Midwest Generation had contractual commitments for the purchase of materials used in the operation of environmental controls equipment. These commitments are estimated to aggregate $3319 million, which consists of $154 million for the remainder of 2013 and $1815 million for 2014.

At September 30, 2013, EME's other subsidiaries had contractual commitments primarily related to turbine operations and maintenance agreements. These commitments are estimated to aggregate $88 million, which consists of $5 million for the

Table of Contents

remainder of 2013, $31 million for 2014, $27 million for 2015, $17 million for 2016, $7 million for 2017, and $1 million thereafter.

Guarantees and Indemnities

EME and certain of its subsidiaries have various financial and performance guarantees and indemnity agreements which are issued in the normal course of business. The contracts discussed below ~~included~~include performance guarantees.

Environmental Indemnities Related to the Midwest Generation Plants

In connection with the acquisition of the Midwest Generation plants, EME and Midwest Generation agreed to indemnify Commonwealth Edison Company (Commonwealth Edison) with respect to specified environmental liabilities before and after December 15, 1999, the date of sale. The indemnification obligations are reduced by any insurance proceeds and tax benefits related to such indemnified claims and are subject to a requirement that Commonwealth Edison takes all reasonable steps to mitigate losses related to any such indemnification claim. Also, in connection with the Powerton and Joliet Sale Leaseback, EME agreed to indemnify the owner-lessors for specified environmental liabilities. These indemnities are not limited in term or amount. Due to the nature of the obligations under these indemnities, a maximum potential liability cannot be determined. Commonwealth Edison has advised EME that Commonwealth Edison believes it is entitled to indemnification for all liabilities, costs, and expenses that it may be required to bear as a result of the litigation discussed below under "—Contingencies—Midwest Generation New Source Review and Other Litigation," and one of the Powerton-Joliet owner-lessors has made a similar request for indemnification. Except as discussed below, EME and Midwest Generation have not recorded a liability related to these environmental indemnities.

Midwest Generation entered into a supplemental agreement with Commonwealth Edison and Exelon Generation Company LLC on February 20, 2003 to resolve a dispute regarding interpretation of Midwest Generation's reimbursement obligation for asbestos claims under the environmental indemnities set forth in the Asset Sale Agreement. Under this supplemental agreement, Midwest Generation agreed to reimburse Commonwealth Edison and Exelon Generation for 50% of specific asbestos claims pending as of February 2003 and related expenses less recovery of insurance costs and agreed to a sharing arrangement for liabilities and expenses associated with future asbestos-related claims as specified in the agreement. The obligations under this agreement are not subject to a maximum liability. The supplemental agreement had an initial five-year term with an automatic renewal provision for subsequent one-year terms (subject to the right of either party to terminate); pursuant to the automatic renewal provision, the supplemental agreement has been extended until February 2014. There were approximately ~~248~~276 cases for which Midwest Generation was potentially liable that had not been settled and dismissed at ~~March~~September 3130, 2013. Midwest Generation had $53 million recorded in LSTC at ~~March~~September 3130, 2013 related to this contractual indemnity. For discussion of LSTC, see Note 1415—Restructuring Activities.

Indemnities Related to the Homer City Plant (EME only)

In connection with the 1999 acquisition of the Homer City plant from New York State Electric & Gas Corporation (NYSEG) and Pennsylvania Electric Company (Penelec) (the sellers), Homer City agreed to indemnify the sellers with respect to specified environmental liabilities before and after the date of sale. EME guaranteed this indemnity obligation of Homer City. In connection with Homer City's divestiture of assets to an affiliate of General Electric Capital Corporation (GECC) on December 14, 2012, EME re-affirmed its guaranty to NYSEG and Penelec. Also in connection with the recent asset transfer to the GECC affiliate, all operative documents with respect to Homer City's sale leaseback (including all EME indemnities in favor of the former owner-lessors) were terminated. In connection with the transfer, the GECC affiliate did not assume (and Homer City retained) liabilities for monetary fines and penalties for violations of environmental laws or environmental permits prior to the closing date. EME has not recorded a liability related to this indemnity. For discussion of the New Source Review lawsuit filed against Homer City, see "—Contingencies—Homer City New Source Review and Other Litigation."

Table of Contents

Indemnities Provided under Asset Sale and Sale Leaseback Agreements

The asset sale agreements for the sale of EME's international assets contain indemnities from EME to the purchasers, including indemnification for taxes imposed with respect to operations of the assets prior to the sale and for pre-closing environmental liabilities. Not all indemnities under the asset sale agreements have specific expiration dates. At ~~March~~September 3130, 2013, EME had $1920 million recorded in LSTC related to these matters. For discussion of LSTC, see Note 1415—Restructuring Activities.

In connection with the Powerton and Joliet Sale Leaseback and, previously, a sale leaseback transaction related to the Collins Station in Illinois, EME, Midwest Generation, and another wholly owned subsidiary of EME entered into tax indemnity agreements. Under certain of these tax indemnity agreements, Midwest Generation, as the lessee in the Powerton and Joliet Sale Leaseback, agreed to indemnify the respective owner-lessors for specified adverse tax consequences that could result from certain situations set forth in each tax indemnity agreement, including specified defaults under the respective leases. Although the Collins Station lease terminated in April 2004, Midwest Generation's indemnities in favor of its former lease equity investors are still in effect. EME provided similar indemnities in the Powerton and Joliet Sale Leaseback. The potential indemnity obligations under these tax indemnity agreements could be significant. Due to the nature of these potential obligations, EME and Midwest Generation cannot determine a range of estimated obligations which would be triggered by a valid claim from the owner-lessors. EME and Midwest Generation have not recorded a liability for these matters.

EME provided similar indemnities in the Powerton and Joliet Sale Leaseback. The potential indemnity obligations under these tax indemnity agreements could be significant. Due to the nature of these potential obligations, EME and Midwest Generation cannot determine a range of estimated obligations which would be triggered by a valid claim from the owner-lessors. EME and Midwest Generation have not recorded a liability for these matters.

Other Indemnities

EME and Midwest Generation provide other indemnifications through contracts entered into in the normal course of business. These include, among other things, indemnities for specified environmental liabilities and for income taxes with respect to assets sold. EME's and Midwest Generation's obligations under these agreements may or may not be limited in terms of time and/or amount, and in some instances, EME and Midwest Generation may have recourse against third parties. EME and Midwest Generation cannot determine a range of estimates and have not recorded a liability related to these indemnities.

Contingencies

In addition to the matters disclosed in these notes, EME and Midwest Generation are involved in other legal, tax, and regulatory proceedings before various courts and governmental agencies regarding matters arising in the ordinary course of business. EME and Midwest Generation believe the outcome of these other proceedings, individually and in the aggregate, will not materially affect their results of operations or liquidity.

Midwest Generation New Source Review and Other Litigation

In August 2009, the United States Environmental Protection Agency (US EPA) and the State of Illinois filed a complaint in the United States District Court for the Northern District of Illinois alleging that Midwest Generation or Commonwealth Edison performed repair or replacement projects at six Illinois coal-fired electric generating stations in violation of the Prevention of Significant Deterioration (PSD) requirements and of the New Source Performance Standards of the Clean Air Act (CAA), including alleged requirements to obtain a construction permit and to install controls sufficient to meet best available control technology (BACT) emission rates. The US EPA also alleged that Midwest Generation and Commonwealth Edison violated certain operating permit requirements under Title V of the CAA. Finally, the US EPA alleged violations of certain opacity and particulate matter standards at the Midwest Generation plants. In addition to seeking penalties ranging from $25,000 to $37,500 per violation per day, the complaint called for an injunction ordering Midwest Generation to install controls sufficient to meet BACT emission rates at all units subject to the complaint and other remedies. The remedies sought by the plaintiffs in the lawsuit could go well beyond the requirements of the Combined Pollutant Standard (CPS). Several Chicago-based environmental action groups intervened in the case.

Nine of the ten PSD claims raised in the complaint have been dismissed, along with claims related to alleged violations of Title V of the CAA, to the extent based on the dismissed PSD claims, and all claims asserted against Commonwealth Edison and EME. The dismissals were affirmed by the Seventh Circuit Court of Appeals in July 2013. The court denied a motion to dismiss a claim by the Chicago-based environmental action groups for civil penalties in the remaining PSD claim but noted that the plaintiffs will be required to convince the court that the statute of limitations should be equitably tolled. The court did not address other counts in the complaint that allege violations of opacity and particulate matter limitations under the Illinois State Implementation Plan and Title V of the CAA. The dismissals have been certified as "partial final judgments" capable of appeal, and an appeal is pending before the Seventh Circuit Court of Appeals. The remaining claims have been stayed pending the appeal. In February 2012, certain of the environmental action groups that had intervened in the case entered into an agreement with Midwest Generation to dismiss without prejudice all of their opacity claims as to all defendants. The agreed upon motion to dismiss was approved by the court on March 26, 2012.

Table of Contents

In January 2012, two complaints were filed against Midwest Generation in Illinois state court by residents living near the Crawford and Fisk Stations on behalf of themselves and all others similarly situated, each asserting claims of nuisance, negligence, trespass, and strict liability. The plaintiffs seek to have their suits certified as a class action and request injunctive relief, as well as compensatory and punitive damages. The complaints are similar to two complaints previously filed in the United States District Court for the Northern District of Illinois, which were dismissed in October 2011 for lack of federal jurisdiction. Midwest Generation's motions to dismiss the cases were denied in August 2012, following which the plaintiffs filed amended complaints alleging substantially similar claims and requesting similar relief. Midwest Generation has filed motions to dismiss the amended complaints, and these complaints are stayed as a result of the Chapter 11 Cases.

In October 2012, Midwest Generation and the Illinois Environmental Protection Agency entered into Compliance Commitment Agreements outlining specified environmental remediation measures and groundwater monitoring activities to be undertaken at its Powerton, Joliet, Crawford, Will County, and Waukegan generating stations. ~~Also in October 2012, several environmental groups filed a complaint before the Illinois Pollution Control Board against~~ Midwest Generation, ~~alleging~~has ~~violations~~submitted ofcertification to the Illinois ~~groundwater~~Environmental ~~standards~~Protection ~~through~~Agency ~~the~~that ~~operation~~all ofcompliance ~~coal~~measures ~~ash~~have disposal ponds at its Powerton, Joliet, Waukegan, and Will County generating stations.

In December 2012, the Sierra Club filed a complaint before the Illinois Pollution Control Board against Midwest Generation, alleging violations of sulfur dioxide (SO2) emissions standards at its Powerton, Joliet, Waukegan, and Will County generating stations. The complaint is based on alleged violations of the US EPA National Ambient Air Quality Standards (NAAQS) regulations for 1-hour SO2, which have not yet been incorporated into any specific state implementation plan in Illinois. The complaint requests the imposition of civil penalties, injunctive relief, and the imposition of further reductions on SO2 emissions to offset past emissions. The complaint is now stayed as a result of the Chapter 11 Cases.33

Also in October 2012, several environmental groups filed a complaint before the Illinois Pollution Control Board against Midwest Generation, alleging violations of the Illinois groundwater standards through the operation of coal ash disposal ponds at its Powerton, Joliet, Waukegan, and Will County generating stations. The complaint requests the imposition of civil penalties, injunctive relief, and remediation. The matter is currently stayed as a result of the Chapter 11 Cases, although that stay was lifted in part in April 2013 so that the proceedings could continue for the sole purpose of adjudicating Midwest Generation's motion to dismiss the complaint. On October 3, 2013, the Pollution Control Board denied Midwest Generation's motion to dismiss the complaint.

In December 2012, the Sierra Club filed a complaint before the Illinois Pollution Control Board against Midwest Generation, alleging violations of sulfur dioxide (SO₂) emissions standards at its Powerton, Joliet, Waukegan, and Will County generating stations. The complaint is based on alleged violations of the US EPA National Ambient Air Quality Standards (NAAQS) regulations for 1-hour SO₂, which have not yet been incorporated into any specific state implementation plan in Illinois. The complaint requests the imposition of civil penalties, injunctive relief, and the imposition of further reductions on SO₂emissions to offset past emissions. The complaint is currently stayed as a result of the Chapter 11 Cases. On October 16, 2013, the Bankruptcy Court heard argument on the Sierra Club's motion to lift the automatic stay. The court took the matter under advisement.

Adverse decisions in these cases could involve penalties, remedial actions, and damages that could have a material impact on the financial condition and results of operations of Midwest Generation and EME. EME cannot predict the outcome of these matters or estimate the impact on the Midwest Generation plants, or EME's and Midwest Generation's results of operations, financial position, or cash flows. EME and Midwest Generation have not recorded a liability for these matters.

Homer City New Source Review and Other Litigation (EME only)

In January 2011, the US EPA filed a complaint in the United States District Court for the Western District of Pennsylvania against Homer City, the sale leaseback owner participants of the Homer City plant, and two prior owners of the Homer City plant. The complaint alleged violations of the PSD and Title V provisions of the CAA as a result of projects in the 1990s performed by prior owners without PSD permits and the subsequent failure to incorporate emissions limitations that meet BACT into the station's Title V operating permit. In addition to seeking penalties ranging from $32,500 to $37,500 per violation per day, the complaint called for an injunction ordering Homer City to install controls sufficient to meet BACT emission rates at all units subject to the complaint and for other remedies. The PADEP, the State of New York, and the State of New Jersey intervened in the lawsuit. In October 2011, all of the claims in the US EPA's lawsuit were dismissed with prejudice. AnThe ~~appeal of the~~ dismissal iswas ~~pending~~affirmed ~~before~~by the United States Court of Appeals for the Third Circuit in August 2013.

Environmental Remediation

Legislative and regulatory activities by federal, state, and local authorities in the United States relating to energy and the environment impose numerous restrictions and requirements with respect to the operation of EME's existing facilities, including the Midwest Generation plants, and affect the timing, cost, location, design, construction, and operation of new facilities by EME's subsidiaries, as well as the cost of mitigating the environmental impacts of past operations.

With respect to potential liabilities arising under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) or similar laws for the investigation and remediation of contaminated property, EME and Midwest Generation accrue a liability to the extent the costs are probable and can be reasonably estimated. Midwest Generation had accrued a probable amount of approximately $8 million at September 30, 2013 for estimated environmental investigation and remediation costs for two stations at the Midwest Generation plants. This estimate is based upon the number of sites, the scope of work, and the estimated costs for investigation and/or remediation where such expenditures could be reasonably estimated. EME and Midwest Generation also have identified sites for which a reasonable estimate cannot be made. Future estimated costs may vary based on changes in regulations or requirements of federal, state or local governmental agencies, changes in technology, and actual costs of disposal. In addition, future remediation costs will be affected by the nature and extent of contamination discovered at the sites that require remediation. Given the prior history of the operations at its facilities, EME and Midwest Generation cannot be certain that the existence or extent of all contamination at its sites has been fully identified.

Chevron Adversary Proceeding (EME only)

In December 2012, Chevron Kern River Company and Chevron Sycamore Cogeneration Company filed a complaint against Southern Sierra Energy Company and Western Sierra Energy in the Chapter 11 Cases. The plaintiffs and defendants are partners in the Kern River and Sycamore projects. The complaint alleged that the filing of the Chapter 11 Cases constituted a default under the partnership agreements related to those projects, entitling the defendants to expel the plaintiffs from the partnerships and pay for their interests at a price based on the net book value of the partnerships, and sought a declaratory judgment, injunctive relief, and relief from the automatic stay in support of those alleged remedies. In January 2013, the Bankruptcy Court denied the plaintiffs' request for relief from the automatic stay and a preliminary injunction. The plaintiffs ~~have~~ filed a notice of appeal, and the defendants moved to stay proceedings until the plaintiffs' appeal was decided. In September 2013, the U.S. District Court issued an order denying the plaintiffs' request for leave to appeal the denial of the preliminary injunction, and permitting their appeal from denial of the motion for relief from the automatic stay.

Midwest Generation Environmental Compliance Plans and Costs

On April 4, 2013, Midwest Generation was granted a variance, subject to various conditions, by the Illinois Pollution Control Board from the CPS system-wide annual SO2 emission rate in 2015 and 2016 and an extension of the Waukegan Unit 8's unit specific retrofit requirements from December 31, 2014 until May 31, 2015. Among the conditions of the variance, the Illinois Pollution Control Board accelerated the unit specific retrofit requirements of Powerton Unit 6 to December 31, 2014 and ~~eliminated~~required ~~shutting~~the ~~down~~retrofitting of Waukegan Unit 7 by December 31, 2014. asMidwest aGeneration ~~compliance~~has ~~option~~accepted the variance. As a result of the variance, it is more likely that Midwest Generation ~~has~~will 35install ~~days~~environmental controls at Waukegan Unit 7, which had been impaired from an accounting perspective during the fourth quarter of 2011. If Midwest Generation ultimately decides to ~~request~~install ~~reconsideration~~environmental orcontrols at Waukegan Unit 7, less of Midwest Generation's available liquidity will be available to ~~seek~~install environmental controls at other units.

Greenhouse Gas Regulation

In September 2013, the US EPA issued proposed regulations governing greenhouse gas (GHG) emissions from new electric generating stations. The US EPA intends to issue proposed GHG emission standards for reconstructed and existing electric generating stations in June 2014 and to promulgate such standards in June 2015. States would be required to submit their implementation plans responding to such guidelines to the US EPA one year after the regulations are promulgated.

Greenhouse Gas Litigation

In April 2013, the United States Court of Appeals for the Fifth Circuit dismissed, as to EME and three wholly owned EME subsidiaries, the plaintiffs' appeal of the Mississippi federal district court's dismissal of a lawsuit filed in March 2012 against a large number of defendants (including EME and the three subsidiaries). The plaintiffs had alleged that defendants' activities resulted in emissions of substantial quantities of ~~greenhouse~~GHG ~~gases~~ that have contributed to climate change and sea level rise, which in turn were alleged to have increased the destructive force of Hurricane Katrina.

~~Cross-State Air Pollution Rule~~35

The United States and several environmental groups have petitioned the U.S. Supreme Court for a review of the United States Court of Appeals for the District of Columbia Circuit's August 2012 decision, which vacated the US EPA's Cross-State Air Pollution Rule and directed the US EPA to continue administering the Clean Air Interstate Rule pending the promulgation of a valid replacement.

The U.S. Supreme Court has agreed to review the United States Court of Appeals for the District of Columbia Circuit's August 2012 decision, which vacated the US EPA's Cross-State Air Pollution Rule and directed the US EPA to continue administering the Clean Air Interstate Rule pending the promulgation of a valid replacement.

Water Quality

Regulations under the Clean Water Act that would affect cooling water intake structures at generating facilities, previously expected to be finalized by June 2013, are now expected in November 2013.

In June 2013, the US EPA proposed changes to the Steam Electric Guideline Regulation which sets discharge limits for various operations which discharge to waters of the United States. EME is reviewing the proposed rule and intends to provide comments. The rule is scheduled for issuance by May 2014.

33Note 13. Impairment of Long-Lived Assets (EME, Midwest Generation)

In connection with the preparation of its financial statements in the third quarter of 2013, Midwest Generation concluded, based on continued low realized energy and capacity prices, high fuel costs and low generation and further analysis of its capital allocation strategy, that indicators of potential impairment existed for its Will County Station and an impairment evaluation was performed.

The long-lived asset group that was subject to the impairment evaluation was determined to include the property, plant and equipment of the station. Management updated the probability weighted future undiscounted cash flows expected to be received at the Will County Station and concluded that such amounts did not recover its carrying amount. Forecasted commodity prices and plant dispatch levels are the most significant input into the cash flow estimates. However, as part of these alternative cash flow scenarios, management considered a shortened estimated useful life of the station if environmental improvements were not made.

To measure the amount of the impairment loss, management used the market approach which considers sales of similar facilities and numerous recent decisions by other power generators to shut down similar coal plants rather than install additional equipment corroborated by the income approach which considers discounted cash flows. This resulted in an impairment charge related to the Will County Station of $464 million. The estimated fair value of zero for the Will County Station was determined using both observable inputs and unobservable inputs, which are Level 3 inputs as defined by accounting guidance for fair value measurements. These inputs included a range of zero to $169 per kilowatt hour of recent transactions for scrubbed coal plants in similar markets.

Note 14. Discontinued Operations (EME only)

In September 2012, Homer City, a wholly owned indirect subsidiary of EME, and Homer City Generation, L.P., an affiliate of GECC, entered into the Homer City Master Transaction Agreement (MTA) for the divestiture by Homer City of substantially all of its remaining assets and certain specified liabilities. Accordingly, in the third quarter of 2012, Homer City met the definition of a discontinued operation and was classified separately on EME's consolidated financial statements. In December 2012, the transaction closed and Homer City Generation, L.P. assumed control of Homer City. On May 2, 2013, the Homer City Debtors filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code. For further discussion, see Note 15—Restructuring Activities and Note 16—Condensed Combined Debtors' Financial Information.

Effective May 1, 2013, Homer City withdrew from the benefit plan that provided postretirement medical, dental, vision, and life insurance coverage to certain Homer City retirees, effectively terminating access and company subsidy for these programs. Employees who were eligible for the plan continued to receive coverage for these benefits up to June 30, 2013. As a result of the withdrawal from the plan, EME recorded a pre-tax gain of approximately $30 million in income (loss) from operations of discontinued subsidiaries on the consolidated statements of operations.

Note 1415. Restructuring Activities (EME, Midwest Generation)

EME eliminated approximately 150 positions in its regional and corporate offices and generating stations in April 2013, which included 120 positions at Midwest Generation. EME will record charges in administrative and general expense on its consolidated statements of operations of approximately $10 million in the second quarter of 2013. Midwest Generation will record its share of these charges, a total of $6 million, in administrative and general expense on its consolidated statements of operations in the second quarter of 2013.

LSTC

EME's LSTC are summarized below:

In connection with the filing of the Chapter 11 Cases, EME classified both its $3.7 billion unsecured senior notes and $154 million of accrued interest related to the unsecured senior notes as LSTC and ceased accruing interest expense. The accrued interest reclassified to LSTC primarily relates to $97 million and $38 million of interest payments that were due on November 15 and December 17, 2012, respectively, that EME did not make. Unpaid contractual interest for the three and nine months ended September 30, 2013 was $70 million and $211 million, respectively.

Through this process, EME and Midwest Generation may identify additional liabilities that need to be recorded as LSTC and the Bankruptcy Court may determine liabilities currently estimated as part of LSTC are without merit. The claims resolution process may take considerable time to complete. The resolution of such claims could result in material adjustments to EME or Midwest Generation's financial statements. Determination of how liabilities will ultimately be treated cannot be made until the Bankruptcy Court approves a plan of reorganization. Accordingly, the ultimate amount or treatment of such liabilities is not determinable at this time.

As of the date of this filing, EME and Midwest Generation have received 1,996 and 333 proofs of claim, respectively. New and amended claims may be filed in the future, including claims amended to assign value to claims originally filed with no value. EME and Midwest Generation are in the process of reconciling such claims to the amounts listed in LSTC. LSTC have been recorded based on the expected probable claim, which is subject to judgment and could change as new information develops during the reconciliation process. Differences in liability amounts estimated and claims filed by creditors have been and will continue to be investigated and resolved, including the filing of objections with the Bankruptcy Court as appropriate. Through this process, EME and Midwest Generation may identify that additional liabilities need to be recorded as LSTC and the Bankruptcy Court may determine that liabilities currently estimated as part of LSTC are without merit. The claims resolution process may take considerable time to complete. The resolution of such claims could result in material adjustments to EME or Midwest Generation's financial statements. Determination of how liabilities will ultimately be treated cannot be made until the Bankruptcy Court approves a plan of reorganization. Accordingly, the ultimate amount or treatment of such liabilities is not determinable at this time.

Reorganization Items

Reorganization items represent the direct and incremental costs of bankruptcy, such as professional fees, LSTC claim adjustments, and losses related to terminated contracts that are probable and can be estimated. Professional fees primarily relate to legal and other consultants working directly on the bankruptcy filing.

EME's and Midwest Generation's significant items in reorganization charges consisted of:

35NRG Sale

On October 18, 2013, EME, Midwest Generation, and certain other Debtor Entities entered into a Plan Sponsor Agreement (the PSA) with NRG Energy, Inc. (NRG), NRG Holdings Inc., the Official Committee of Unsecured Creditors appointed in the Chapter 11 Cases, the counterparties to the Powerton and Joliet Sale Leaseback and certain of EME’s noteholders that are signatories to the PSA, that provides for the parties to support and pursue confirmation by the Bankruptcy Court of a chapter 11 plan (the Plan), that will implement a reorganization of the Debtor Entities through a sale of substantially all of the assets of EME to NRG pursuant to an Asset Purchase Agreement (the Acquisition Agreement). The PSA contains representations, warranties and covenants of the parties to support and pursue confirmation of the Plan.

The Acquisition Agreement between EME, NRG and NRG Energy Holdings Inc. (the Purchaser), a wholly owned subsidiary of NRG, provides for the sale of substantially all of EME’s assets, including the outstanding equity interests in certain of

Table of Contents

EME’s direct subsidiaries (and thereby such subsidiaries’ assets and liabilities), EME’s cash and cash equivalents and EME’s interest in substantially all of the other assets used in the operation of EME’s and its subsidiaries’ businesses (the Acquired Assets) to the Purchaser upon Bankruptcy Court confirmation and consummation of the Plan. Upon closing, the Purchaser will assume substantially all of the liabilities related to the Acquired Assets, including, among other things, (i) all liabilities of EME under the Powerton and Joliet leases, other than the Powerton and Joliet Cure Amount; (ii) all trade and vendor accounts payable and accrued liabilities arising from the operation of the Debtor Entities’ businesses prior to the date of the closing of the transaction; and (iii) all cure amounts and other liabilities of the Debtor Entities other than the Homer City Debtors and certain agreed-upon excluded liabilities.

In particular, with respect to the Powerton and Joliet leases, at the closing of the transaction, NRG would (i) replace the existing EME guarantees with NRG guarantees; (ii) replace EME as a party to the tax indemnity agreements relating to the Powerton and Joliet leases; and (iii) covenant to make a capital investment in the Powerton and Joliet Stations, provided that NRG will not be obligated to make capital investments in excess of $350 million.

In consideration of the foregoing, at the closing of the transaction, EME would retain all liabilities with respect to the payment of the Powerton and Joliet Cure Amount and would be responsible for bearing the costs of such cure payment for all amounts due under the lease before January 2, 2014. In addition, the intercompany note issued by EME for the benefit of Midwest Generation, would be canceled, Midwest Generation would assume the Powerton and Joliet leases and the other operative documents related thereto, as modified by mutual agreement of the parties, and all monetary defaults under each lease would be cured at closing.

The Acquired Assets do not include, among other things, (i) the Homer City Debtors, (ii) potential litigation claims of EME against its parent, EIX or (iii) various tax attributes of EME, including tax losses, tax loss carryforwards, tax credits and tax refunds. Pursuant to the Acquisition Agreement, the total purchase price to be paid by the Purchaser for the Acquired Assets is $2.635 billion, subject to certain adjustments provided in the Acquisition Agreement, as well as the assumption of certain indebtedness of EME’s subsidiaries and other liabilities. The Acquisition Agreement provides for $350 million of the total purchase price to be paid in the form of 12,671,977 newly issued shares of NRG’s common stock to be registered with the Securities and Exchange Commission on a Form S-1 Registration Statement (the Registration Statement) and the remainder to be paid in cash.

The Plan generally provides for each of EME’s unsecured creditors to receive a pro rata portion of the NRG stock and cash consideration to be paid by the Purchaser to EME under the Acquisition Agreement (less certain distributions to be paid to other creditors of EME).

The Acquisition Agreement contains various closing conditions including, among other things, (i) the confirmation of a Plan of Reorganization and the entry of a Confirmation Order by the Bankruptcy Court; (ii) receipt of applicable government approvals, including FERC approval and the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976; and (iii) the declaration of effectiveness of the Registration Statement for, and the approval for listing on the New York Stock Exchange of, the common stock to be issued as a portion of the purchase price. The Acquisition Agreement contains certain representations and warranties made by EME, NRG and the Purchaser. There are also various pre-closing and post-closing covenants binding on the parties.

Under the Acquisition Agreement, EME is permitted to solicit other competing acquisition proposals through December 6, 2013 and EME has agreed not to solicit or encourage competing acquisition proposals after this date.

The Acquisition Agreement provides specific termination rights to each party, which include a right to terminate if certain milestone dates are not met, for material breaches of the Acquisition Agreement not cured within a specified period or if EME enters into or seeks approval of a superior proposal. EME may terminate the deal to enter into a superior proposal at any time prior to entry of a Confirmation Order. Under specified circumstances, NRG will be entitled to receive a cash fee of $65 million, and expense reimbursement of all reasonable and documented out-of-pocket expenses, if the Acquisition Agreement is terminated.

EDISON MISSION ENERGY OVERVIEW

EME and ~~Midwest~~19 Generation continue to experience operating losses due to low realized energy and capacity prices, high fuel costs, and low generation at the Midwest Generation plants. These operating losses are a continuation of trends initially experienced in the fourth quarter of 2011. These adverse trends coupled with pending debt maturities and the need to retrofit the Midwest Generation plants to comply with governmental regulations were expected to exhaust EME's and Midwest Generation's liquidity. Consequently, on December 17, 2012, EME and 16 of its wholly owned subsidiaries, Camino Energy Company, Chestnut Ridge Energy Company, Edison Mission Energy Fuel Services, LLC, Edison Mission Fuel Resources, Inc., Edison Mission Fuel Transportation, Inc., Edison Mission Holdings Co., Edison Mission Midwest Holdings Co., Midwest Finance Corp., Midwest Generation EME, LLC, Midwest Generation, Midwest Generation Procurement Services, LLC, Midwest Peaker Holdings, Inc., Mission Energy Westside, Inc., San Joaquin Energy Company, Southern Sierra Energy Company, and Western Sierra Energy Company (~~collectively,~~ the Debtor Entities) have filed voluntary petitions for relief under Chapter 11 ~~(the Chapter 11 Cases)~~ of the United States Bankruptcy Code (the Bankruptcy Code) in the United States Bankruptcy Court for the Northern District of Illinois, Eastern Division (the Bankruptcy Court). The Debtor Entities ~~remain~~chapter in11 ~~possession~~cases ~~of their property and continue their business operations uninterrupted as "debtors-in-possession" under~~ (the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. Other than the Debtor Entities, none of EME's other direct or indirect subsidiaries is a debtor in the Chapter 11 Cases.) are being

Activities in the Chapter 11 Cases have focused on providing a smooth transition into Chapter 11 and developing strategic initiatives and alternatives to maximize the value of the Debtor Entities' estates. The Debtor Entities are also conducting an ongoing investigation on the settlement transaction (the Settlement Transaction) with Edison International (EIX). The Transaction Support Agreement (the Support Agreement), which was executed in December 2012 by EME, certain of its unsecured noteholders and EIX, contemplates that EME will seek Bankruptcy Court approval to enter into the Settlement Transaction by May 16, 2013. However, the Support Agreement permits EME to take any action, or refrain from taking any 44

In ~~addition, the lease documents prevent the certificate holders from foreclosing until 180 days from the date of default.~~

The filing of the Chapter 11 Cases constitutes an event of default under Midwest Generation's obligations related to leases of the Powerton Station and Units 7 and 8 of the Joliet Station (the Powerton and Joliet Sale Leaseback) and under instruments governing the Senior Lease Obligation Bonds issued to finance these leases. EME, Midwest Generation, the owner-lessors, and certain of the holders of the pass-through certificates of Midwest Generation's lessor debt (the Certificate Holders) have been engaged in ongoing discussions regarding the ultimate disposition of the leases. In June 2013, EME and Midwest Generation agreed, among other things, to make monthly rental payments of $3.75 million beginning in July 2013 and to pay certain professional fees for the owner-lessors and Certificate Holders in exchange for an extension of the deadline to assume or reject the Powerton and Joliet leases and the agreement of the Certificate Holders to forbear and to direct the lease indenture trustee and pass-through trustee to forbear from seeking payment of any administrative claim for rent under the Powerton and Joliet leases (except the monthly partial rental payments of $3.75 million under the agreement) before the earlier of the effective date of a chapter 11 plan for Midwest Generation or a sale of substantially all of the assets of Midwest Generation. The parties filed a motion detailing the terms of this agreement and the Bankruptcy Court approved the extension of the statutory deadline by which the Debtor Entities must assume or reject the Powerton and Joliet leases until December 31, 2013.

•	$61 million increase in results from the Midwest Generation plants primarily attributable to lower plant operations costs and lower support fuel costs, partially offset by lower capacity revenues;


•	$58 million increase in results from Walnut Creek which achieved commercial operation in the second quarter of 2013 and began selling power under its power purchase agreement with SCE in June 2013;


•	$24 million decrease in corporate administrative and general expenses due to lower departmental spending and a reduction in shared services charges from EIX;

•

$17 million increase in the results of the renewable energy projects primarily attributable to the results of Broken Bow I and Crofton Bluffs wind projects that achieved commercial operation in the fourth quarter of 2012, higher merchant pricing at the Goat wind project, and sale of Oklahoma state tax credits at the Taloga wind project, partially offset by higher plant operations costs at the High Lonesome wind project and income allocated to outside investors of Capistrano Wind Partners; and


•	$11 million increase in the results of the Big 4 Projects due to a property tax refund at Watson and higher revenue, partially offset by higher fuel costs and operating expenses.

The nine-month increase in Adjusted EBITDA was partially offset by the following:


•	$15 million decrease in the results of the Sunrise project due to lower revenues as the project transitioned to merchant generation; and


•	$6 million decrease attributable to lower distributions received from the Doga project.

Midwest Generation Environmental Compliance Plans and Costs

All of Midwest Generation's Illinois coal-fired electric generating units are subject to an Illinois regulation called the Combined Pollutant Standard (CPS), which sets emission limits for mercury, nitrogen oxide and SO2 and specifies the control technologies that are to be installed on some units by specified dates. Midwest Generation must ~~either~~ install the required technology by the specified deadline, or shut down the unit, or curtail generation to be in compliance with the CPS.

On April 4, 2013, Midwest Generation was granted a variance, subject to various conditions, by the Illinois Pollution Control Board from the CPS system-wide annual SO2 emission rate in 2015 and 2016 and an extension of the Waukegan Unit 8's unit specific retrofit requirements from December 31, 2014 until May 31, 2015. Among the conditions of the variance, the Illinois Pollution Control Board accelerated the unit specific retrofit requirements of Powerton Unit 6 to December 31, 2014 and ~~eliminated~~required ~~shutting~~the ~~down~~retrofitting of Waukegan Unit 7 by December 31, 2014. asMidwest Generation has accepted the variance. As a ~~compliance~~result ~~option~~of the variance, it is more likely that Midwest Generation will install environmental controls at Waukegan Unit 7, which had been impaired from an accounting perspective during the fourth quarter of 2011. If Midwest Generation ~~has~~ultimately 35decides ~~days~~to install environmental controls at Waukegan Unit 7, less of Midwest Generation's available liquidity will be available to ~~request~~install ~~reconsideration~~environmental orcontrols at other units. For further discussion related to ~~seek~~impairment apolicies ~~modification~~on EME and 45Midwest ~~days~~Generation's unit of account, refer to ~~accept~~EME's and Midwest Generation's combined annual report on Form 10-K for the ~~variance.~~year ended December 31, 2012.

Decisions whether ~~or not~~ to proceed with retrofitting of any particular units to comply with CPS requirements for SO2 and mercury emissions, including those that have received permits, are subject to a number of factors such as market conditions, regulatory and legislative developments, liquidity, forecasted commodity prices, and capital and operating costs applicable at the time decisions are required or made. Midwest Generation is not expected to generate sufficient cash flows from operating activities, and will likely need to borrow funds, receive additional contributions from EME, or find other sources of capital to fund the retrofits of its coal-fired plants. EME's ability to provide capital to Midwest Generation is subject to its own liquidity constraints and oversight by EME's creditors.

41All capital projects needed to comply with nitrogen oxide emission limits of the CPS have been completed. Capital projects needed to comply with mercury limits of the CPS have been completed except for the projects that must be undertaken on Waukegan Unit 7 and Will County Unit 3. Waukegan Unit 7 and Will County Unit 3 are subject to a unique CPS requirement to convert hot-side electrostatic precipitator (ESP) equipment to cold-side ESP or fabric filtration equipment in order to reduce mercury emissions. Final decisions to retrofit or shut down units will be made in light of the timing requirements under the CPS and other applicable environmental regulations and the economic projections of those retrofits, on a unit-by-unit basis, at the time the decision is made. Based on work to date through September 30, 2013, the estimated costs of retrofitting the Midwest Generation plants for full CPS compliance, as well as compliance with the federal Mercury and Air Toxics Standards (MATS), are as follows:

to the corresponding periods of 2012. Lower plant operations costs were attributable to the voluntary shutdown of the coal-fired Fisk and Crawford Stations in August 2012 and lower planned maintenance costs due to a reduction in scope of projects. Lower support fuel costs were primarily attributable to a decline in usage and lower prices of activated carbon and urea. For additional discussion of Midwest Generation's operating results, see "Edison Mission Energy Overview—Highlights of Operating Results."

Included in fuel costs were unrealized gains (losses) of none and $2 million for the third quarter of 2013 and 2012, respectively, and none and $(2) million for the nine months ended September 30, 2013 and 2012, respectively, due to oil futures contracts that were accounted for as economic hedges. These contracts were entered into as economic hedges of the variable fuel price component of rail transportation costs and expired at the end of 2012.

Reconciliation of Non-GAAP Disclosures and Statistical Definitions

Average realized energy price and average realized fuel costs are presented as an aid in understanding the operating results of Midwest Generation. These statistical measures are both non-GAAP performance measures since they exclude unrealized gains or losses recorded as operating revenues or fuel costs. Management believes that these measures are meaningful for investors as this information reflects the impact of hedge contracts at the time of actual generation in period-over-period comparisons or as compared to real-time market prices. These measures may not be comparable to those of other companies.

Average Realized Energy Price

The average realized energy price reflects the average price at which energy is sold into the market including the effects of hedges, real-time and day-ahead sales, and PJM Interconnection, LLC (PJM) fees and ancillary services. It is determined by dividing (i) operating revenues adjusted for unrealized gains (losses) and other non-energy related revenues by (ii) generation as shown in the table below. Revenues related to capacity sales are excluded from the calculation of average realized energy price. The following table shows the average realized energy price for Midwest Generation:

Statistical Definitions

• Equivalent availability reflects the impact of the unit's inability to achieve full load, referred to as derating, as well as outages which result in a complete unit shutdown. The Midwest Generation plants are not available during periods of planned and unplanned maintenance. The equivalent availability factor is defined as the number of MWh the coal plants are available to generate electricity divided by the product of the capacity of the coal plants (in megawatts (MW)) and the number of hours in the period.


•	The capacity factor indicates how much power a unit generated compared to the maximum amount of power that could be generated according to its rating. It is defined as the actual number of MWh generated by the coal plants divided by the product of the capacity of the coal plants (in MW) and the number of hours in the period.


•	The load factor indicates how much power a unit generated compared to the maximum amount of power that a unit was available to generate electricity. It is determined by dividing capacity factor by the equivalent availability factor.

• The forced outage rate refers to forced outages and deratings excluding events outside of management's control as defined by North American Electric Reliability Corporation (NERC). Examples include floods, tornado damage, and transmission outages.

Beginning in 2013, Midwest Generation ceased accruing interest income on its intercompany loan with EME. The declines in interest expense primarily relate to the Powerton and Joliet Sale Leaseback.

Income Taxes

The valuation allowance Midwest Generation recorded in the ~~first~~three ~~quarter~~months ofand nine months ended September 30, 2013 resulted in a significant variance between the effective tax rate and the statutory rate. Midwest Generation's effective tax rate was 3637% and 38% for the three and nine months ended ~~March 31~~September 30, 2012, respectively. Midwest Generation's effective tax rates also differ from the federal statutory rate of 35% due to state income taxes.

Unpaid contractual interest for the three and nine months ended September 30, 2013 was $70 million and $211 million, respectively. For additional information, see "Combined Notes to Consolidated Financial Statements—Note 15. Restructuring Activities—LSTC."

EME did not make $97 million and $38 million of interest payments on its $3.7 billion of unsecured senior notes due on November 15, 2012 and December 17, 2012, respectively. In connection with the filing of the Chapter 11 Cases, EME

classified the unsecured senior notes as LSTC and ceased accruing interest expense. Unpaid contractual interest for the period ending March 31, 3013 was $70 million.

Income Taxes

~~EME's~~The ~~effective~~valuation ~~tax~~allowance ~~rates~~EME ~~were~~recorded 4%in ~~and 57% for~~ the three months ~~ended~~and ~~March~~nine ~~31,~~months ~~2013~~ended ~~and 2012~~September 30, ~~respectively. The valuation allowance EME recorded in the first quarter of~~ 2013 resulted in a significant variance between the effective tax rate and the statutory rate. In addition, EME's effective tax rates differ from the federal statutory rate of 35% due to production tax credits, estimated state income tax benefits allocated from EIX, and taxes on income allocated to noncontrolling interests. Production tax credits of $21 58 million and $19 48 million were included in income taxes for the ~~three~~nine months ended ~~March 31~~September 30, 2013 and 2012, respectively. Estimated state income tax benefits allocated from EIX of ~~$1 million~~none and $37 million were recognized for the ~~three~~nine months ended ~~March 31~~September 30, 2013 and 2012, respectively. The benefit for state taxes was lower in 2012 due to an adjustment in state apportionment factors. For further discussion, see "Combined Notes to Consolidated Financial Statements—Note 7. Income Taxes."

Results of Discontinued Operations

~~Loss~~Income (loss) from discontinued operations, net of tax, was $(1) million and $24(76) million for the ~~first~~third quarter ended ~~March~~September 3130, 2013 and 2012, respectively, and $16 million and $(129) million for the nine months ended September 30, 2013 and 2012, respectively. The 2013 gain from discontinued operations primarily reflects the withdrawal from the benefit plan that provided postretirement medical, dental, vision, and life insurance coverage to certain Homer City retirees and the 2012 loss from discontinued operations primarily reflects the results related to Homer City plant operations. For additional information, see "Combined Notes to Consolidated Financial Statements—Note 1314. Discontinued Operations."

Seasonality

Due to fluctuations in electric demand resulting from warm weather during the summer months and cold weather during the winter months, electric revenues from Midwest Generation's coal-fired plants normally vary substantially on a seasonal basis. In addition, maintenance outages generally are scheduled during periods of lower projected electric demand (spring and fall), further reducing generation and increasing major maintenance costs which are recorded as an expense when incurred. Accordingly, Midwest Generation's income is seasonal and has significant variability from quarter to quarter. Seasonal fluctuations may also be affected by changes in market prices. For further discussion regarding market prices, see "Market Risk Exposures—Commodity Price Risk—Energy Price Risk."

EME's third quarter equity in income from its unconsolidated energy projects is normally higher than equity in income related to other quarters of the year due to seasonal fluctuations and higher energy contract prices during the summer months.

EME, as a holding company, does not directly operate any revenue-producing generation facilities. EME relies on cash distributions and tax payments from its projects and tax benefits received under a tax-allocation agreement with EIX to meet its obligations, including debt service obligations on long-term debt. The timing and amount of payments from EIX under the tax-allocation agreement is uncertain and the timing and amount of distributions from EME's subsidiaries may be restricted. For further discussion, see "Combined Notes to Consolidated Financial Statements—Note ~~5. Debt and Credit Agreements—Restricted Net Assets of Subsidiaries," and "—Note~~ 7. Income Taxes."

Midwest Generation generates liquidity through cash flows from operations and payments by EME under an intercompany loan issued in connection with the Powerton and Joliet Sale Leaseback. AsHowever, aat ~~result of the Chapter~~December ~~11 Cases~~31, ~~EME did not make the scheduled principal and interest payment of $61 million due to Midwest Generation on January 2~~2012, ~~2013 and~~ Midwest Generation recorded a $1.4 billion charge, equal to the full carrying amount of the loan and accrued interest, during the fourth quarter of 2012. Future payments, if any, made by EME under the loan will be dependent upon the overall resolution of the Chapter 11 Cases. Likewise, prior to the filing of the Chapter 11 Cases, EME and ~~Midwest~~ceased ~~Generation~~accruing ~~had~~interest ~~entered~~income ~~into~~associated ~~a forbearance agreement~~ with ~~various parties to~~ the ~~Powerton~~intercompany ~~and Joliet Sale Leaseback and the Senior Lease Obligation Bonds issued to finance these leases~~loan. ~~Under~~EME ~~the terms of the forbearance agreement, Midwest Generation~~ did not make the scheduled ~~lease~~principal ~~payments~~and interest payment of $7661 million due on both January 2, 2013 ~~but on February 15, 2013, did pay the ratable portion of the rent due under the leases attributable to the period between December 17, 2012~~ and ~~January~~July 2, 2013 ~~of $7 million~~. ~~The~~Upon ~~forbearance~~completion ~~agreement has expired, however, the automatic stay provisions~~ of the ~~Bankruptcy~~NRG Code and the lease documents prevent the owner-lessors and the certificate holders from exercising rights or remedies against the Debtor Entities that may arise from these defaults until 180 days from the date of default. EME and Midwest Generation must assume the Powerton and Joliet Sale ~~Leaseback by July 1~~, ~~2013~~this orloan ~~else it will be automatically rejected. EME~~ and ~~Midwest~~accrued ~~Generation~~interest ~~are~~would ~~currently~~be ~~analyzing these options~~canceled. ~~The Chapter 11 Cases could also potentially give rise to counterparty rights and remedies under other documents.~~

Likewise, prior to the filing of the Chapter 11 Cases, EME and Midwest Generation entered into a forbearance agreement with various parties to the Powerton and Joliet Sale Leaseback and the Senior Lease Obligation Bonds issued to finance these leases. Under the terms of the forbearance agreement, Midwest Generation did not make the scheduled lease payment of $76 million on January 2, 2013, but on February 15, 2013, did pay the ratable portion of the rent due under the leases attributable to the period between December 17, 2012 and January 2, 2013 of $7 million. This forbearance agreement has expired. In June 2013, EME and Midwest Generation agreed, among other things, to make monthly rental payments of $3.75 million beginning in July 2013, in lieu of the scheduled $76 million lease payment due on July 2, 2013. In addition, the Bankruptcy Court approved the extension of the statutory deadline by which the Debtor Entities must assume or reject the Powerton and Joliet leases until December 31, 2013. Upon completion of the NRG Sale, Midwest Generation would assume the Powerton and Joliet leases. EME would retain all liabilities with respect to the payment of the cure amount as set forth in the Asset Purchase Agreement (the Powerton and Joliet Cure Amount). The cure amount would have been approximately $150 million at September 30, 2013.

The Chapter 11 Cases could also potentially give rise to counterparty rights and remedies under other documents.

Capital Investment Plan

Midwest Generation's forecasted environmental expenditures are based on using dry scrubbing with sodium-based sorbents and upgrading particulate removal systems to comply with CPS requirements for SO2 and mercury emissions and the United States Environmental Protection Agency's (US EPA's) ~~regulation~~MATS regulations on hazardous air pollutant emissions. On April 4, 2013, Midwest Generation was granted a variance, subject to various conditions, by the Illinois Pollution Control Board from the CPS system-wide annual SO2 emission rate in 2015 and 2016 and an extension of the Waukegan Unit 8's unit specific retrofit requirements from December 31, 2014 until May 31, 2015.

Construction on the Walnut Creek Project began in June 2011. During March and April 2013, the project completed testing and commissioning of the ~~first four~~ units and began selling power into the merchant market. The ~~final unit began start-up and testing in March 2013 and is expected to be available for merchant operation in advance of the~~ power purchase agreement with SCE ~~that~~began ~~begins~~ in June 2013. The nonrecourse financing associated with the Walnut Creek Project ~~will~~converted ~~convert~~ to 10-year amortizing term loans byin June ~~30,~~ 2013~~, subject to meeting specified conditions, such as achieving commercial operation~~.

At March 31, 2013, EME's development pipeline of potential wind projects was approximately 580 MW. Future development of the wind portfolio is dependent on the availability of third-party capital. To the extent that third-party capital is available, the success of development efforts will depend upon, among other things, obtaining permits and agreements necessary to support an investment. Further development is also dependent upon federal subsidies in the form of production tax credits, which remain available for wind generation facilities that are under construction by December 31, 2013.

Cash Flows From Operating Activities

The fluctuation in cash provided by operating activities from continuing operations in ~~the first quarter~~ 2013 as compared to cash used in operating activities from continuing operations in ~~the first quarter~~ 2012 was attributable to lower rent payments for the leased facilities at the Powerton and Joliet plants due to the forbearance agreement (see "—Available Liquidity"), and fewer coal purchases as existing coal inventory was utilized. The fluctuation was also attributable to tax-allocation payments received, ~~and~~net ~~less~~of ~~collateral~~payments, ~~posted~~of ~~with~~$9 million ~~counterparties~~in 2013 compared to tax-allocation payments, net of receipts, of $168 million in 2012. These increases were partially offset by lower capacity revenues at Midwest Generation. The remaining changes relate to the timing of cash receipts and disbursements related to working capital items. In addition, less cash is being disbursed in 2013 due to the classification of pre-petition obligations as LSTC.

Cash Flows From Operating Activities

The decrease in cash provided by operating activities in ~~the first quarter~~ 2013 as compared to ~~the first quarter~~ 2012 was primarily attributable to lower capacity ~~prices~~revenues, ~~lower~~which ~~average realized energy prices, and higher fuel prices. This decrease~~ was partially offset by fewer coal purchases as existing coal inventory was utilized. The remaining changes relate to the timing of cash receipts and disbursements related to working capital items. In addition, less cash is being disbursed in 2013 due to the classification of pre-petition obligations as LSTC.

Cash Flows From Financing Activities

The decrease ~~in 2013~~ was primarily due to lower rent payments for the leased facilities at the Powerton and Joliet plants due to the forbearance agreement (see "—Available Liquidity") in ~~the first quarter of~~ 2013 as compared with ~~the first quarter of~~ 2012.

Cash Flows From Investing Activities

Net cash used in investing activities consisted primarily of capital expenditures for 2013 and 2012.

Margin, Collateral Deposits and Other Credit Support for Energy Contracts

To reduce their exposure to market risk, EME and Midwest Generation hedge a portion of their electricity price exposure through Edison Mission Marketing & Trading, Inc. (EMMT). In connection with entering into contracts, EMMT may be required to support its risk of nonperformance through parent guarantees, margining, or other credit support. EME has entered into guarantees in support of certain of EMMT's hedging and trading activities. However, EME and EMMT have historically also provided collateral in the form of cash and letters of credit for the benefit of counterparties. EME's ability to provide collateral during the Chapter 11 Cases is limited. For further details, see "Combined Notes to Consolidated Financial Statements—Note 6. Derivative Instruments and Hedging Activities—~~Margin~~EME—Summary ~~and~~of ~~Collateral~~Derivative ~~Deposits~~Instruments."

Midwest Generation anticipates that sales of its power through EMMT may require additional credit support, depending upon market conditions and the strategies adopted for the sale of this power. Changes in forward market prices and margin requirements and increases in merchant sales could further increase the need for credit support related to hedging activities. Midwest Generation has only a limited ability to provide collateral to support bilateral contracts for power and fuel to the extent that any such transactions relate to its merchant energy operations. Pursuant to an order from the Bankruptcy Court, such credit support would require prior written notice to certain of Midwest Generation's unsecured creditors, who would have an opportunity to object. In the event of an objection, Midwest Generation would not be able to provide collateral unless the Bankruptcy Court orders otherwise. There is no assurance that Midwest Generation will be able to provide credit support to EMMT.

Future cash collateral requirements for hedging and trading activities may be higher than the margin and collateral requirements at ~~March~~September 3130, 2013, if wholesale energy prices change or if EMMT enters into additional transactions. EME estimates that, under existing arrangements, margin and collateral requirements for energy and congestion contracts outstanding as of ~~March~~September 3130, 2013 could increase by approximately $162 million over the remaining life of the contracts using a 95% confidence level.

EME’s approach to trading and risk management depends, in part, on the ability to use clearing brokers to enter into market transactions. As a result of its financial position, EME has limited access to enter into such transactions and has been subject to increased initial collateral and margin requirements. There is no assurance that EME will continue to be able to utilize clearing brokers. If EME becomes unable to utilize clearing brokers, it may seek to execute bilateral transactions with third parties which could be unavailable on commercially reasonable terms or at all.

~~EME's Intercompany Tax-Allocation Agreement~~ 59

EME is included in the consolidated federal and combined state income tax returns of EIX and is eligible to participate in tax-allocation agreements with EIX and its subsidiaries. EME's right to receive payments under the tax-allocation agreements and the timing and amount of those payments are dependent on the inclusion of EME in the consolidated income tax returns of EIX and other factors, including the amount of consolidated taxable income and net operating loss carryforwards of EIX, and other tax items of EME and other subsidiaries of EIX. Based on the application of the factors cited above, EME is obligated during periods it generates taxable income to make payments under the tax-allocation agreements. Tax-allocation receipts and payments may also be affected by redetermination of utilization of net operating losses resulting from carryback of net operating losses on a consolidated basis or settlement of tax liabilities for prior periods. During 2012, EIX modified the tax-allocation agreements to provide for termination of EME's participation on December 31, 2013. The Settlement Transaction contemplates that EME's participation in the tax-allocation agreements would be extended through the earlier of the effective date of EME's plan of reorganization and December 31, 2014. However, there can be no assurance that the

During the third quarter of 2013, EIX filed its federal consolidated tax return for the year 2012. In connection with EIX's finalization of the tax return, EME recorded a non-cash contribution from EIX of $32 million related to tax benefits which EME had previously believed would be used in EIX consolidated tax return on a statutory basis but would not be paid under the tax-allocation agreements. In addition, during the first nine months of 2013, EME received a net tax-allocation payment from EIX of approximately $7 million of which $6 million was treated as an equity contribution as it was a partial payment for tax benefits previously recorded as non-cash distributions. In total, EME recorded contributions from EIX related to the tax-allocation agreements of $38 million during 2013.

Dividend Restrictions in Major Financings

Each of EME's direct or indirect subsidiaries is organized as a legal entity separate and apart from EME and its other subsidiaries. Assets of certain EME subsidiaries, including some wind projects in portfolio financings and projects under construction, are not available to satisfy EME's obligations or the obligations of any of its other subsidiaries. However, unrestricted cash or other assets that are available for distribution may, subject to applicable law and the terms of financing arrangements of the parties, be advanced, loaned, paid as dividends, or otherwise distributed or contributed to EME or to its subsidiary holding companies. For further details, including the restricted net assets of EME, see "Combined Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements—Restricted Net Assets of Subsidiaries."

MARKET RISK EXPOSURES (EME and Midwest Generation, except as noted)

EME's and Midwest Generation's primary market risk exposures are associated with the sale of electricity and capacity from, and the procurement of fuel for, their merchant power plants. These market risks arise from price fluctuations of electricity, capacity, fuel, emission allowances, and transmission rights. Additionally, EME's financial results can be affected by fluctuations in interest rates. EME and Midwest Generation manage these risks in part by using derivative instruments in accordance with established policies and procedures. Both EME and Midwest Generation use commodity derivatives for non-trading purposes. EME also has derivatives used for trading purposes.

Derivative Instruments

Unrealized Gains and Losses

Unrealized gains and losses from derivative instruments (other than the effective portion of derivatives that qualify for hedge accounting) are recorded as part of operating revenues or fuel costs. The following table summarizes unrealized gains (losses) from non-trading activities:

	Three Months Ended March 31,
	Three Months EndedSeptember 30,						Nine Months EndedSeptember 30,

Fair Value Disclosures

In determining the fair value of EME's and Midwest Generation's derivative positions, third-party market pricing is used where available. For further explanation of the fair value hierarchy and a discussion of EME's and Midwest Generation's derivative instruments, see "Combined Notes to Consolidated Financial Statements—Note 4. Fair Value Measurements" and "—Note 6. Derivative Instruments and Hedging Activities."

Commodity Price Risk

Energy Price Risk

EME is exposed to energy price risk through its indirect ownership of Midwest Generation, 428 MW of merchant renewable energy projects in PJM and Electric Reliability Council of Texas (ERCOT), ~~and~~ 50% of the Sunrise project, and its proprietary trading. Midwest Generation is exposed to energy price risk through sales of energy and capacity into the PJM market. Energy and capacity from Midwest Generation are sold under terms, including price, duration, and quantity, arranged by EMMT with customers through a combination of bilateral agreements (resulting from negotiations or from auctions), forward energy sales, and spot market sales. Power is sold into PJM at spot prices based upon locational marginal pricing.

The following table depicts the average historical market prices for energy per megawatt-hour at the Northern Illinois Hub for the first ~~quarters~~nine months of 2013 and 2012:

	2013				2012
24-Hour Average Historical Market Prices1	$	3132.1058			$28.56	~~27.20~~


¹	Energy prices were calculated at the Northern Illinois Hub delivery point using historical hourly day-ahead prices as published by PJM or provided on the PJM web-site.

2014 calendar "strip"2		$	32.91


¹	Energy prices were determined by obtaining broker quotes and information from other public sources relating to the Northern Illinois Hub delivery point.


²	Market price for energy purchases for the entire calendar year.

Power prices remained low in the first nine months of 2013 due to an abundance of low-priced natural gas. ~~and~~Forward ~~forward~~ market prices at the Northern Illinois Hub fluctuate as a result of a number of factors, including natural gas prices, transmission congestion, changes in market rules, electricity demand (which in turn is affected by weather, economic growth, and other factors), plant outages in the region, and the amount of existing and planned power plant capacity. The actual spot prices for electricity delivered by Midwest Generation into these markets may vary materially from the forward market prices set forth in the preceding table.

EMMT engages in hedging activities for Midwest Generation to hedge the risk of future changes in the price of electricity. The following table summarizes the hedge positions at ~~March 31~~September 30, 2013 for electricity expected to be generated during the remainder of 2013:

	MWh (in thousands)					Average price/MWh1
Midwest Generation2		~~2,769~~908					$	36.6114

The above hedge positions include forward contracts for the sale of power and futures contracts during different periods of the year and the day. Market prices tend to be higher during on-peak periods and during summer months, although there is significant variability of power prices during different periods of time. Accordingly, the above hedge positions are not directly comparable to the 24-hour Northern Illinois Hub prices set forth above.

2 Includes hedging transactions primarily at the American Electric Power (AEP)/Dayton Hub and the Northern Illinois Hub, both in PJM, and to a lesser extent the Indiana Hub in Midwest Independent Transmission System Operator (MISO).

Capacity Price Risk

EME and Midwest Generation are exposed to capacity price risk through sales of capacity into the PJM market. Under the Reliability Pricing Model (RPM), capacity commitments are made in advance to provide a long-term pricing signal for construction and maintenance of capacity resources. The following table summarizes the status of capacity sales for Midwest Generation at ~~March~~September 3130, 2013:

	RPM Capacity Sold in Base Residual Auction			Other Capacity Purchases,Net of Sales1							AggregateAveragePrice perMW-day
	MW	Price perMW-day		MW			Average Price per MW-day

June 1, 2016 to May 31, 2017	3,331	59.37		—				—			59.37

1 Other capacity sales and purchases, net includes contracts executed in advance of the RPM base residual auction to hedge the price risk related to such auction, participation in RPM incremental auctions, and other capacity transactions entered into to manage capacity risks.


²	Includes the impact of a 13 MW capacity swap transaction executed between Big Sky and Midwest Generation.

The RPM auction capacity price for the delivery period of June 1, 2016 to May 31, 2017 of $59.37 per MW-day for the western portion of PJM, affecting Midwest Generation, was substantially down from the prior auction mainly due to increased competition from new or upgrades to existing, gas-fired generation, higher imports from nearby markets and low growth in demand due to the slow economy. The impact of lower capacity prices for these periods compared to previous years will have an adverse effect on Midwest Generation's revenues unless such lower capacity prices are offset by increased energy prices.

Revenues from the sale of capacity beyond the periods set forth above will depend upon the amount of capacity available and future market prices either in PJM or nearby markets if those facilities have an opportunity to capture a higher value associated with those markets.

Coal Price Risk

Midwest Generation purchases coal primarily from the Southern Powder River Basin (PRB) of Wyoming. Coal purchases are made under a variety of supply agreements. The following table summarizes the amount of coal Midwest Generation has under contract at ~~March~~September 3130, 2013:

	April through December 2013	2014
	October through December 2013	2014
Amount of Coal Under Contract in Millions of Equivalent Tons1	1013.73	9.8


¹	The amount of coal under contract in equivalent tons is calculated based on contracted tons and applying an 8,800 Btu equivalent.

Midwest Generation is subject to price risk for purchases of coal that are not under contract. Market prices of PRB coal based on 8,800 Btu per pound heat content and 0.8 pounds of SO2 per million British thermal units (MMBtu) sulfur content remained relatively flat during the nine months ended September 30, 2013 from 2012 year-end prices.

Basis Risk

During the ~~three~~nine months ended ~~March 31~~September 30, 2013, day-ahead prices at the individual busbars of Midwest Generation compared to the AEP/Dayton Hub, Indiana Hub, and Northern Illinois Hub were on average lower by 98%, higher by 21%, and lower by less than 1%, respectively. During the ~~three~~nine months ended ~~March 31~~September 30, 2012, day-ahead prices at the individual busbars of Midwest Generation compared to the AEP/Dayton Hub, Indiana Hub, and Northern Illinois Hub were on average lower by 6%, ~~higher~~lower by 31%, and higher by 1%, respectively. Differences in day-ahead pricing between the individual busbars of Midwest Generation generally arise due to transmission congestion.

Credit Risk

The credit risk exposure from counterparties of merchant energy hedging and trading activities is measured as the sum of net receivables (accounts receivable less accounts payable) and the current fair value of net derivative assets. EME's subsidiaries enter into master agreements and other arrangements in conducting such activities which typically provide for a right of setoff in the event of bankruptcy or default by the counterparty. At ~~March~~September 3130, 2013, the balance sheet exposure as described above, by the credit ratings of EME's counterparties, was as follows:

	March 31, 2013
	September 30, 2013
(in millions)	Exposure2		Collateral			Net Exposure
Credit Rating1
A or higher	$	8466	$	—		$	8466
A-	—		—			—
BBB+	51		—			51
BBB	—		—			—
BBB-	—		—			—
Below investment grade	1—		(1—		)	—
Total	$	9067	$	(1—	)	$	8967


¹	EME assigns a credit rating based on the lower of a counterparty's Standard & Poor's Ratings Services (S&P) or Moody's Investors Service, Inc. (Moody's) rating. For ease of reference, the above table uses the S&P classifications to summarize risk, but reflects the lower of the two credit ratings.


²	Exposure excludes amounts related to contracts classified as normal purchase and sales and non-derivative contractual commitments that are not recorded on the consolidated balance sheet, except for any related accounts receivable.

The credit risk exposure set forth in the above table is composed of $5042 million of net accounts receivable and payables and $4025 million representing the fair value of derivative contracts. The exposure is based on master netting agreements with the related counterparties. Credit ratings may not be reflective of the actual related credit risks. In addition to the amounts set forth in the above table, EME's subsidiaries have posted aan $5985 million cash margin in the aggregate with various counterparties to support hedging and trading activities. The margin posted to support these activities also exposes EME to credit risk of the related entities.

The coal plants sell electric power generally into the PJM market by participating in PJM's capacity and energy markets or transacting in capacity and energy on a bilateral basis. Sales into PJM accounted for approximately 5862% and 100% of EME's and Midwest Generation's consolidated operating revenues, respectively, for the ~~three~~nine months ended ~~March~~September 3130, 2013. At ~~March~~September 3130, 2013, EME's account receivable due from PJM was $4433 million.

EME's turbine supply agreements contain significant suppliers' obligations ~~related to the manufacturing and delivery of turbines, and payments,~~ for ~~delays in delivery and for~~ failure to meet performance obligations and warranty agreements. EME's reliance on these contractual provisions is subject to credit risks. Generally, these are unsecured obligations of the turbine manufacturer. A material adverse development with respect to EME's turbine suppliers may have a material impact on EME's wind projects. Two of EME's turbine suppliers, Suzlon Wind Energy Corporation and Clipper Windpower, LLC (Clipper), have been experiencing significant adverse credit and liquidity issues. As a result, EME's ability to enforce performance and warranty guarantees is subject to the credit risk of these counterparties. In April 2013, ~~certain of~~ EME's ~~subsidiaries~~ entered into a settlement agreement with ~~certain~~ Clipper ~~entities~~ with respect to claims under and termination of the turbine supply, maintenance, and warranty agreements and other related documents.

Interest Rate Risk (EME only)

Interest rate changes can affect earnings and the cost of capital for capital improvements or new investments in power projects. EME mitigates the risk of interest rate fluctuations for a number of its project financings by arranging for fixed rate financing or variable rate financing with interest rate swaps, interest rate options, or other hedging mechanisms. For further details, see "Combined Notes to Consolidated Financial Statements—Note 4. Fair Value Measurements" and "—Note 6. Derivative Instruments and Hedging Activities."

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

There have been no significant developments with respect to legal proceedings specifically affecting EME and Midwest Generation since the filing of EME's and Midwest Generation's combined annual report on Form 10-K for the year ended December 31, 2012, except as follows:

In October 2012, several environmental groups filed a complaint before the Illinois Pollution Control Board against Midwest Generation, alleging violations of the Illinois groundwater standards through the operation of coal ash disposal ponds at its Powerton, Joliet, Waukegan, and Will County generating stations. The complaint requests the imposition of civil penalties, injunctive relief, and remediation. The matter is currently stayed as a result of the Chapter 11 Cases, although that stay ~~has~~was ~~been~~ lifted in April 2013 in part so that the proceedings may continue for the sole purpose of adjudicating Midwest Generation's motion to dismiss the complaint. On October 3, 2013, the Pollution Control Board denied Midwest Generation's motion to dismiss the complaint.

In July 2013, the United States Court of Appeals for the Seventh Circuit affirmed the U.S. District Court's dismissal of nine of the ten Prevention of Significant Deterioration (PSD) claims asserted against Midwest Generation and EME by the State of Illinois and the Department of Justice, along with claims related to alleged violations of Title V of the Clean Air Act to the extent based on the dismissed PSD claims, and all claims asserted against Commonwealth Edison.

In August 2013, the United States Court of Appeals for the Third Circuit affirmed the U.S. District Court's dismissal of all of claims asserted in the lawsuit filed by the US EPA in January 2011 against Homer City, the sale leaseback owner participants of the Homer City plant, and two prior owners of the Homer City plant.

In September 2013, the U.S. District Court issued an order denying the request made by Chevron Kern River Company and Chevron Sycamore Cogeneration Company for leave to appeal the denial of the preliminary injunction in the Chevron adversary proceeding, and permitting their appeal from denial of the motion for relief from the automatic stay.

ITEM 1A. RISK FACTORS

~~The~~In ~~risks~~addition ~~described~~to inthe risk factors below, refer to "Item 1A. Risk Factors" on page 24 of EME's and Midwest Generation's combined annual report on Form 10-K for the year ended December 31, 2012 for a discussion of the risks, uncertainties and other important factors which could materially affect EME's and Midwest Generation's business, financial condition, or future results. The risks described in EME's and Midwest Generation's combined annual report on Form 10-K and in this combined report are not the only risks facing EME and Midwest Generation. Additional risks and uncertainties that are not currently known, or that are currently deemed to be immaterial, also may materially adversely affect EME's and Midwest Generation's business, financial condition or future results.

Risks Related to Restructuring

Failure to complete the NRG Sale could negatively affect EME's future business and financial results.

On October 18, 2013, EME announced the execution of the Acquisition Agreement with NRG and the Purchaser. Before the NRG Sale may be completed, the parties must satisfy all conditions set forth in the Acquisition Agreement, including, among other things, (i) the confirmation of a Plan of Reorganization and the entry of a Confirmation Order by the Bankruptcy Court, (ii) receipt of applicable government approvals, including FERC approval and the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, (iii) the declaration of effectiveness of Registration Statement for, and the approval for listing on the New York Stock Exchange of, the NRG common stock to be issued as a portion of the purchase price. Governmental authorities may impose conditions on the completion, or require changes to the terms, of the NRG transaction, and if the conditions or requirements are not satisfied or waived the NRG Sale will not be consummated. These conditions or changes could have the effect of delaying completion of, or imposing additional costs on, the NRG transaction.

If the NRG Sale is not completed, EME still will be required to pay its own costs relating to the NRG Sale, including legal, accounting, financial advisory, filing and printing costs. Also, in certain specified circumstances, EME may be required to pay NRG a cash fee of $65 million plus reimbursement of all reasonable and documented out-of-pocket expenses if the Acquisition Agreement is terminated.

Table of Contents

EME will be subject to various uncertainties and contractual restrictions while the NRG Sale is pending that could adversely affect its financial results.

Uncertainty about the effect of the NRG Sale on employees, customers, suppliers and others may have an adverse effect on EME’s business. These uncertainties may impair EME’s ability to attract, retain and motivate key personnel and could cause its customers, suppliers and other contract counterparties to seek to change existing business relationships to EME's disadvantage.

The pursuit of the NRG Sale and the preparation for the transition of EME’s assets from EME to NRG may place a significant burden on EME’s management and internal resources. Employee retention will be particularly challenging prior to the completion of the NRG transaction, due to uncertainty about future employment prospects with NRG.

ITEM 4. MINE SAFETY DISCLOSURES

There have been no significant developments with respect to mine safety disclosures for EME since the filing of EME's and Midwest Generation's combined annual report on Form 10-K for the year ended December 31, 2012.
