MIDWEST GENERATION, LLC AND SUBSIDIARIES
COMBINED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies (EME and Midwest Generation, except as noted)
Chapter 11 Cases
EME and Midwest 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) filed voluntary petitions for relief under Chapter 11 (the Chapter 11 Cases) of the Bankruptcy Code.
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 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. The automatic stay provisions of the Bankruptcy Code prevent the owner-lessors from exercising rights or remedies against the Debtor Entities that may arise from these defaults. In addition, the lease documents prevent the certificate holders from foreclosing until 180 days from the date of default. 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. The Chapter 11 Cases may also constitute events of default under the $191 million nonrecourse financing of the Wildorado, San Juan Mesa and Elkhorn Ridge wind projects (the Viento II Financing) and the $69 million nonrecourse financing of the High Lonesome wind project (High Lonesome Financing). The various lenders and EME subsidiary borrowers associated with the financings have executed short-term forbearance agreements which expire in July 2013. The Chapter 11 Cases could also potentially give rise to counterparty rights and remedies under other documents. For further discussion, see Note 5—Debt and Credit Agreements and Note 9—Commitments and Contingencies—Powerton and Joliet Sale Leaseback.
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. EME and Midwest Generation are currently developing a plan for their restructuring, but there is no assurance such a plan will be successfully implemented. EME's and Midwest Generation's ability to continue as going concerns is dependent on many factors, including the successful development of a confirmed plan of reorganization and an emergence from bankruptcy. Uncertainty as to the outcome of these factors raises substantial doubt about EME's and Midwest Generation's ability 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

Table of Contents

read in conjunction with the financial statements and notes included in EME's and Midwest Generation's 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-month period ended March 31, 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.
Cash Equivalents
Cash equivalents included money market funds totaling $862 million and $615 million for EME and $111 million and $75 million for Midwest Generation at March 31, 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.

As a result of the Chapter 11 Cases, EME did not make the scheduled principal and interest payment of $61 million due to Midwest Generation on January 2, 2013 and Midwest Generation recorded a full valuation allowance against its intercompany loan with EME during the fourth quarter of 2012. At December 31, 2012, Midwest Generation ceased accruing interest income associated with the intercompany loan as future payments, if any, made by EME under the loan will be dependent upon the overall resolution of the Chapter 11 Cases. Interest income from affiliates, included in interest and other income on Midwest Generation's consolidated statements of operations, was none and $28 million during the three months ended March 31, 2013 and 2012, respectively.
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

12
Table of Contents

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.
Accounting Guidance Not Yet Adopted
Joint and Several Liabilities
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.

Note 3. Variable Interest Entities (EME only)
Projects or Entities that are Consolidated
At March 31, 2013 and December 31, 2012, EME consolidated 16 and 15 projects, respectively, with a total generating capacity of 958 megawatts (MW) and 878 MW, respectively, that have noncontrolling interests held by others. Projects consolidated at 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 the terms of the formation documents, preferred equity interests receive 100% of the cash available for distribution up to a scheduled amount to target a certain return and thereafter cash distributions are shared. Cash available for distribution includes 90% of the tax benefits realized by MEHC and contributed to Capistrano Wind Partners.
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 March 31, 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 31, 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.

14
Table of Contents

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.

Money market funds are included in cash and cash equivalents on EME's consolidated balance sheets.
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.

In assessing the fair value of EME's long-term debt, EME primarily uses quoted market prices, except for floating-rate debt for which the carrying amounts were considered a reasonable estimate of fair value. The fair value of EME's long-term debt is classified as Level 2.
The carrying amount of short-term debt approximates fair value.

Note 5. Debt and Credit Agreements (EME only)
Chapter 11 Cases
The filing of the Chapter 11 Cases constitutes an event of default under various financing documents. In addition to the instruments discussed below, the Chapter 11 Cases could also potentially give rise to counterparty rights and remedies under other documents.
Senior Notes
The filing of the Chapter 11 Cases may constitute an event of default under EME's senior notes and, as a result, the principal and interest due under these debt instruments are immediately due and payable. The creditors are stayed from taking any action as a result of the default under Section 362 of the Bankruptcy Code and the obligations related to the senior notes are recorded as part of liabilities subject to compromise (LSTC). For additional information, see Note 14—Restructuring Activities.

Table of Contents

Viento II Financing
The filing of the Chapter 11 Cases may constitute an event of default under the Viento II Financing. A short-term forbearance agreement has been executed with the lenders and the EME subsidiary borrowers to these financing agreements and, as a result, the EME subsidiaries that have obligations pursuant to the Viento II Financing are currently not Debtor Entities in the Chapter 11 Cases. In March 2013, EME paid an approximately $1 million consent fee to extend the expiration date of the forbearance agreement to July 2013. Due to the short-term nature of the agreement, this financing was classified as short-term at March 31, 2013 and December 31, 2012. At March 31, 2013, there was $191 million outstanding under this loan and $23 million of outstanding letters of credit. For additional information, see Note 6—Derivative Instruments and Hedging-Interest Rate Risk Management.
High Lonesome Financing
The filing of the Chapter 11 Cases may constitute an event of default under the documents governing the issuance of the Series 2010A and 2010B Bonds. A short-term forbearance agreement has been executed with the lenders and the EME subsidiary borrower to these financing agreements and, as a result, the EME subsidiaries that have obligations pursuant to the High Lonesome Financing are currently not Debtor Entities in the Chapter 11 Cases. The forbearance agreement expires on July 31, 2013. Due to the short-term nature of the agreements, this financing was classified as short-term at March 31, 2013 and December 31, 2012. As of March 31, 2013, there were $44 million and $25 million outstanding under the Series 2010A and Series 2010B Bonds, respectively, and $11 million of outstanding letters of credit.
Credit Facilities and Letters of Credit
At March 31, 2013, letters of credit under EME's and its subsidiaries' credit facilities aggregated $158 million and were scheduled to expire as follows: $66 million in 2013, $21 million in 2014, $21 million in 2017, $19 million in 2018, $18 million in 2021, and $13 million in 2022. Standby letters of credit include $30 million issued in connection with the power purchase agreement with Southern California Edison Company (SCE), an affiliate of EME, under the Walnut Creek credit facility. At March 31, 2013, EME had $44 million of cash collateral supporting its standby letters of credit. Certain letters of credit are subject to automatic annual renewal provisions.
On February 20, 2013, the Bankruptcy Court approved an agreement between EME and DNB Bank, the lender pursuant to EME's secured letter of credit facility. Pursuant to this agreement, DNB Bank has agreed to forbear from sending notices of non-renewal to beneficiaries of outstanding letters of credit and to allow existing letters of credit to renew automatically in accordance with their terms. In exchange, EME consented to lift the automatic stay to permit DNB Bank to setoff any obligations due and owing under the applicable documents against EME's cash collateral.
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 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 declaratory judgment that the early repayment triggers had been satisfied such that Big Sky would be obligated to make full early repayment of 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.

19
Table of Contents

As of March 31, 2013, $224 million was outstanding under the vendor financing loan at an effective interest rate of 4.14%. 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 as EME does not plan to make an investment in the project and is under no obligation to do so. Subject to lender consent, EME may also choose to sell Big Sky at a loss or, if a restructuring of the loan or a sale effort is unsuccessful, the lender may foreclose on the project resulting in a write-off of the entire investment in the project. At March 31, 2013, EME's investment in the Big Sky wind project consisted of assets of $464 million and liabilities of $369 million.
Restricted Net Assets of Subsidiaries
EME's 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.

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.

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.
EME
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.
As a result of the Chapter 11 Cases and the short-term forbearance agreements that have been executed with the lenders and the EME subsidiary borrowers, it is no longer probable that the future interest payments associated with the Viento II Financing will occur. Accordingly, the cash flow hedge associated with these interest rate swaps was prospectively discontinued. Because the underlying forecasted transactions remain at least reasonably possible, the fair value of the effective portion of these cash flow hedges remains in AOCI and will be reclassified to results of operations when the underlying transactions occur or become probable of not occurring. EME recorded unrealized gains of $1 million in the first quarter of 2013 in operating revenues on the consolidated statements of operations representing changes in the fair value of discontinued interest rate swaps.

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.

Estimated state income tax benefits allocated from EIX of $1 million and $3 million were recognized for the three months ended March 31, 2013 and 2012, respectively.
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. During the first quarter of 2013, EME received a net tax-allocation payment from EIX of approximately $6 million under the tax-allocation agreements. This cash receipt was treated as an equity contribution as it was a partial payment for tax benefits previously recorded as non-cash distributions. At December 31, 2012, $222 million of tax benefits generated by EME that had been utilized in the EIX consolidated tax return on a statutory basis and for which, under the tax-allocation agreements as applied, EME had not yet, and may never be, entitled to be paid were accounted for as non-cash distributions to EME's parent.
Without objectively verifiable evidence supporting the taxable income forecast of the EIX consolidated tax group during 2013 and 2014, EME is not currently able to determine whether it is more likely than not that future tax-sharing payments will occur. Accordingly, EME's deferred tax asset valuation allowance, including the impact in OCI, increased to $503 million at March 31, 2013 from $444 million at December 31, 2012.
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 million, including interest and penalties through March 31, 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.

As a result of the recently recognized losses and the indications of expected future losses, Midwest Generation increased its deferred tax valuation allowance, including the impact in OCI, to $567 million at March 31, 2013 from $533 million at December 31, 2012. 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.

Transfer of Certain Postretirement Benefits to EIX (EME only)
During 2012, EME transferred the executive deferred compensation and executive postretirement benefit liabilities related to active employees to EIX. EME agreed to fund changes to the projected benefit obligation of the executive postretirement benefits and the employer portion of the executive deferred compensation plan through EME's emergence from bankruptcy. During the three months ended March 31, 2013, EME funded $3 million in connection with this agreement.

Note 9. Commitments and Contingencies (EME and Midwest Generation, except as noted)
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 holders. Under the terms of the forbearance agreement, Midwest Generation did not make the scheduled lease payments 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 forbearance agreement has expired, however, the automatic stay provisions of the Bankruptcy 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. The forbearance agreement did not impact the automatic stay or the provisions in the lease documents.
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.

Other Commitments
Capital Commitments
At March 31, 2013, Midwest Generation had firm commitments for capital expenditures totaling approximately $61 million, which are expected to be incurred as follows: $16 million for the remainder of 2013, $8 million for 2014, $20 million for 2015, and $17 million for 2016.
Other Contractual Obligations
At March 31, 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 $33 million, which consists of $15 million for the remainder of 2013 and $18 million for 2014.
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 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 cases for which Midwest Generation was potentially liable that had not been settled and dismissed at March 31, 2013. Midwest Generation had $53 million recorded in LSTC at March 31, 2013 related to this contractual indemnity. For discussion of LSTC, see Note 14—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 31, 2013, EME had $19 million recorded in LSTC related to these matters. For discussion of LSTC, see Note 14—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.
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 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 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 been lifted in part so that the proceedings may continue for the sole purpose of adjudicating 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 SO2 emissions to offset past emissions. The complaint is now stayed as a result of the Chapter 11 Cases.
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. An appeal of the dismissal is pending before the United States Court of Appeals for the Third Circuit.
Also in January 2011, two residents filed a complaint in the United States District Court for the Western District of Pennsylvania, on behalf of themselves and all others similarly situated, against Homer City, the sale leaseback owner participants of the Homer City plant, two prior owners of the Homer City plant, EME, and EIX, claiming that emissions from the Homer City plant had adversely affected their health and property values. The plaintiffs sought to have their suit certified as a class action and requested injunctive relief, the funding of a health assessment study and medical monitoring, as well as compensatory and punitive damages. In October 2011, the claims in the purported class action lawsuit that were based on the federal CAA were dismissed with prejudice, while state law statutory and common law claims were dismissed without prejudice to re-file in state court should the plaintiffs choose to do so. EME does not know whether the plaintiffs will file a complaint in state court.
Adverse decisions in these cases could involve penalties, remedial actions, and damages. EME cannot predict the outcome of these matters or estimate the impact on its results of operations, financial position, or cash flows. EME has not recorded a liability for these matters.
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,

30
Table of Contents

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 March 31, 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.

Note 10. Environmental Developments (EME, Midwest Generation)
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 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 shutting down Waukegan Unit 7 by December 31, 2014 as a compliance option. Midwest Generation has 35 days to request reconsideration or to seek a modification and 45 days to accept the variance.
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 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
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.

EME and Midwest Generation both expect to reclassify unrealized losses on cash flow hedges into earnings in the next 12 months. For further explanation, see discussion under "—Unrealized Losses on Cash Flow Hedges" below.
The after-tax amounts recorded in AOCI at March 31, 2013 and December 31, 2012 for commodity contracts were losses of $8 million and $1 million, respectively, and for interest rate contracts were losses of $68 million and $75 million, respectively. The maximum period over which a commodity cash flow hedge is designated is through December 31, 2013.

Unrealized Losses on Cash Flow Hedges (EME, Midwest Generation)
At March 31, 2013, unrealized losses on cash flow hedges, net of tax, consisted of futures and forward electricity contracts that qualify for hedge accounting. These losses arise because current forecasts of future electricity prices are higher than the contract prices. Approximately $8 million of unrealized losses on cash flow hedges, net of tax, are expected to be reclassified into earnings during the next 12 months. Management expects that reclassification of net unrealized losses will decrease energy revenues recognized at market prices. Actual amounts ultimately reclassified into earnings over the next 12 months could vary materially from this estimated amount as a result of changes in market conditions.

Note 13. Discontinued Operations (EME only)
In September 2012, EME Homer City Generation L.P. (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 in EME's consolidated financial statements. In December 2012, the transaction closed and Homer City Generation, L.P. assumed control of Homer City.

Note 14. 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.

In connection with the filing of the Chapter 11 Cases, Midwest Generation classified $13 million of accrued interest due on the Powerton and Joliet Sale Leaseback as LSTC but did not cease accruing interest expense. For further discussion, see Note 9—Commitments and Contingencies—Powerton and Joliet Sale Leaseback.
Claims
As of the date of this filing, EME and Midwest Generation have received 122 and 42 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. In April 2013, the Bankruptcy Court set June 17, 2013 as the general bar date for potential creditors to file a proof of claim. EME and Midwest Generation are in the process of reconciling such claims to the amounts listed in LSTC. Differences in liability amounts estimated and claims filed by creditors will be investigated and resolved, including the filing of objections with the Bankruptcy Court as appropriate. 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.
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 consultants working directly on the bankruptcy filing.
EME's and Midwest Generation's significant items in reorganization charges consisted of:

Risk Factors" of EME's and Midwest Generation's combined annual report on Form 10-K for the year ended December 31, 2012. Readers are urged to read this entire quarterly report on Form 10-Q and the combined annual report on Form 10-K including the information incorporated by reference, and to carefully consider the risks, uncertainties, and other factors that affect EME's and Midwest Generation's businesses. Forward-looking statements speak only as of the date they are made, and EME and Midwest Generation are not obligated to publicly update or revise forward-looking statements. Readers should review future reports filed by EME and Midwest Generation with the Securities and Exchange Commission.
This MD&A discusses material changes in the results of operations, financial condition and other developments of EME since December 31, 2012, and as compared to the first quarter ended March 31, 2012. This discussion presumes that the reader has read or has access to the MD&A included in Item 7 of EME's and Midwest Generation's combined annual report on Form 10-K for the year ended December 31, 2012.

EDISON MISSION ENERGY OVERVIEW
EME and Midwest 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) 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 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.
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

39
Table of Contents

action, including a decision to pursue an alternative restructuring transaction, that EME determines is consistent with its fiduciary duties.
At the same time, EME has undertaken a number of restructuring related initiatives intended to preserve or increase the value of the Debtor Entities' estates. For instance, Midwest Generation sought, and on April 4, 2013 received, a variance from the CPS system-wide annual SO2 emission rate in 2015 and 2016 and an extension of the Waukegan Unit 8 unit specific retrofit requirements from December 31, 2014 until May 31, 2015. The Debtor Entities have also begun a comprehensive analysis of all of their contractual relationships, with a near-term focus on real property agreements and their other most significant goods and services contracts. As a result of this initiative, the Debtor Entities have renegotiated certain contracts and filed notices with the Bankruptcy Court to reject other contracts. The Bankruptcy Court has extended to July 15, 2013 the statutory deadline by which the Debtor Entities can assume unexpired leases of real property, except for Midwest Generation's leases of the Powerton Station and Units 7 and 8 of the Joliet Station (the Powerton and Joliet Sale Leaseback). 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.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. The automatic stay provisions of the Bankruptcy Code prevent the owner-lessors from exercising rights or remedies against the Debtor Entities that may arise from these defaults. In addition, the lease documents prevent the certificate holders from foreclosing until 180 days from the date of default.

Highlights of Operating Results

Provision (benefit) for income taxes includes the impact of production tax credits and changes in the valuation allowance. For additional information, see "Combined Notes to Consolidated Financial Statements—Note 7. Income Taxes—EME—Effective Tax Rate."
Adjusted EBITDA is equal to net income (loss) under GAAP before interest expense, income tax expense (benefit), depreciation and amortization, adjusted to include the impact of production tax credits and exclude the impact of mark to market of economic hedges of interest rates, gain (loss) on sale of assets, gain (loss) on early extinguishment of debt and leases, impairment of assets and investments, restructuring costs, and reorganization items. This non-GAAP financial measure reflects an additional way of viewing EME's business and augments the understanding of facts and trends affecting the business. This non-GAAP financial measure should not be relied upon to the exclusion of GAAP financial measures and may not be comparable to those of other companies' non-GAAP financial measures having the same or similar names.

Adjusted EBITDA is equal to equity in income (loss) from unconsolidated affiliates.
EME's Adjusted EBITDA for the first quarter of 2013 increased compared to the first quarter of 2012, primarily due to the following items:
•
$10 million increase in energy trading income mainly due to higher revenues from congestion contracts;
•
$12 million increase in the results of the Big 4 Projects due to higher revenue, lower repair costs, and property tax refund accrual, partially offset by higher operating expenses and fuel costs; and
•
$9 million decrease in corporate administrative and general expenses due to lower consulting costs and decrease in the amount and scope of services provided to EME by EIX.
The first quarter increase in Adjusted EBITDA was partially offset by the following item:
•
$29 million decrease in results from the Midwest Generation plants primarily attributable to lower capacity and average realized energy prices and higher fuel prices, partially offset by lower plant operations costs.

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 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 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 shutting down Waukegan Unit 7 by December 31, 2014 as a compliance option. Midwest Generation has 35 days to request reconsideration or to seek a modification and 45 days to accept the variance.
Decisions whether or not to proceed with retrofitting of any particular units to comply with CPS requirements for SO2 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.

41
Table of Contents

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 March 31, 2013, the estimated costs of retrofitting the Midwest Generation plants are as follows:

MIDWEST GENERATION, LLC
Results of Operations
In accordance with GAAP, Midwest Generation accounts for the Powerton and Joliet Sale Leaseback as a lease financing in its separate consolidated financial statements. Accordingly, Midwest Generation records the power plants as assets in a similar manner to a capital lease and records depreciation expense from the power plants and interest expense from the lease financing.

Table of Contents

Operating Income (Loss)
Midwest Generation's operating loss increased $27 million in the first quarter of 2013 compared to the first quarter of 2012. The 2013 increase in operating loss was attributable to lower capacity and average realized energy prices and higher fuel prices, partially offset by lower plant operations costs. 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.
Included in fuel costs were unrealized gains of none and $3 million during the first quarters of 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 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 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 NERC. Examples include floods, tornado damage and transmission outages.

Interest income from affiliate decreased $28 million in the first quarter of 2013 compared to the first quarter of 2012. Beginning in 2013, Midwest Generation ceased accruing interest on its intercompany loan with EME.

Income Taxes
The valuation allowance Midwest Generation recorded in the first quarter of 2013 resulted in a significant variance between the effective tax rate and the statutory rate. Midwest Generation's effective tax rate was 36% for the three months ended March 31, 2012. Midwest Generation's effective tax rates also differ from the federal statutory rate of 35% due to state income taxes. For further discussion, see "Combined Notes to Consolidated Financial Statements—Note 7. Income Taxes."

Equivalent availability for renewable energy projects reflects the impact of the projects inability to generate power at full capacity, including outages due to regular maintenance. Equivalent availability is defined as the number of MWh the units are available to generate electricity divided by the product of the capacity of the units (in MW) and the number of hours in the period.
Adjusted EBITDA from renewable energy projects increased $2 million in the first quarter of 2013 compared to the first quarter of 2012. The 2013 increase was attributable to the results of Broken Bow I and Crofton Bluffs wind projects that achieved commercial operation in fourth quarter of 2012 and favorable merchant pricing at Goat and Big Sky wind projects, partially offset by income allocated to outside investors in Capistrano Wind Partners. For additional information, see "Combined Notes to Consolidated Financial Statements—Note 3. Variable Interest Entities—Projects or Entities that are Consolidated—Capistrano Wind Partners."

EME's interest expense decreased $68 million for the first quarter of 2013 compared to the first quarter of 2012. The 2013 decrease in interest expense was primarily due to the fact that EME ceased accruing interest on its $3.7 billion of unsecured senior notes during the pendency of the Chapter 11 Cases.
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

47
Table of Contents

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 effective tax rates were 4% and 57% for the three months ended March 31, 2013 and 2012, 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 million and $19 million were included in income taxes for the three months ended March 31, 2013 and 2012, respectively. Estimated state income tax benefits allocated from EIX of $1 million and $3 million were recognized for the three months ended March 31, 2013 and 2012, respectively. For further discussion, see "Combined Notes to Consolidated Financial Statements—Note 7. Income Taxes."

Results of Discontinued Operations
Loss from discontinued operations, net of tax, was $1 million and $24 million for the first quarter ended March 31, 2013 and 2012, respectively. The 2012 loss from discontinued operations primarily reflects the results related to Homer City. For additional information, see "Combined Notes to Consolidated Financial Statements—Note 13. 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. As a result of the Chapter 11 Cases, EME did not make the scheduled principal and interest payment of $61 million due to Midwest Generation on January 2, 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 Generation had 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 payments 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 forbearance agreement has expired, however, the automatic stay provisions of the Bankruptcy 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 or else it will be automatically rejected. EME and Midwest Generation are currently analyzing these options. 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 emissions and the US EPA's regulation 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 Waukegan Unit 8's unit specific retrofit requirements from December 31, 2014 until May 31, 2015.

The timing of commencing capital projects may vary from the amounts set forth in the above table. For additional information on environmental expenditures, see "Edison Mission Energy Overview—Midwest Generation Environmental Compliance Plans and Costs."
Construction on the Walnut Creek Project began in June 2011. During 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 begins in June 2013. The nonrecourse financing associated with the Walnut Creek Project will convert to 10-year amortizing term loans by 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"), fewer coal purchases as existing coal inventory was utilized, and less collateral posted with counterparties. These increases

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, lower average realized energy prices, and higher fuel prices. This decrease was partially offset by fewer coal purchases as existing coal inventory was utilized.

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 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 and Collateral Deposits."
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 31, 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 31, 2013 could increase by approximately $16 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
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

52
Table of Contents

Settlement Transaction will be consummated. Termination does not relieve any party of any obligations with respect to any tax year beginning prior to the year of termination.
During the first quarter of 2013, EME received a net tax-allocation payment from EIX of approximately $6 million under the tax-allocation agreements. This cash receipt was treated as an equity contribution as it was a partial payment for tax benefits previously recorded as non-cash distributions. At December 31, 2012, $222 million of tax benefits generated by EME that had been utilized in the EIX consolidated tax return on a statutory basis and for which, under the tax-allocation agreements as applied, EME had not yet, and may never be, entitled to be paid were accounted for as non-cash distributions to EME's parent.

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."
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. For further discussion on the Powerton and Joliet Sale Leaseback, see "Combined Notes to Consolidated Financial Statements—Note 9. Commitments and Contingencies."

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:

At March 31, 2013, cumulative unrealized gains of $1 million were recognized from non-qualifying hedge contracts or the ineffective portion of cash flow hedges related to 2013.

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 ERCOT, and 50% of the Sunrise project. 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 of 2013 and 2012:

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 2013 due to an abundance of low-priced natural gas and 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, 2013 for electricity expected to be generated during the remainder of 2013:
 
MWh (in thousands)

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.

Capacity Price Risk
EME and Midwest Generation are exposed to capacity price risk through sales of capacity into the PJM market. Under the RPM, capacity commitments are made in advance to provide a long-term pricing signal for construction and maintenance of capacity resources.

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 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 31, 2013:
 
 
April through December 2013
 
2014
Amount of Coal Under Contract in Millions of Equivalent Tons1
 
10.7

 
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 2013 from 2012 year-end prices.

Basis Risk
During the three months ended March 31, 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 9%, higher by 2% and lower by less than 1%, respectively. During the three months ended March 31, 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 by 3% 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 31, 2013, the balance sheet exposure as described above, by the credit ratings of EME's counterparties, was as follows:

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 $50 million of net accounts receivable and payables and $40 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 a $59 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 58% and 100% of EME's and Midwest Generation's consolidated operating revenues, respectively, for the three months ended March 31, 2013. At March 31, 2013, EME's account receivable due from PJM was $44 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."
