EDISON MISSION ENERGY AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
SEPTEMBER 30, 2011
(Unaudited)


Note 1. Summary of Significant Accounting Policies

Basis of Presentation

Edison Mission Energy's (EME's) significant accounting policies were described in "Note 1—Summary of Significant Accounting Policies" on page 94 of EME's annual report on Form 10-K for the year ended December 31, 2010. EME follows the same accounting policies for interim reporting purposes, with the exception of accounting principles adopted as of January 1, 2011, as discussed below in "—New Accounting Guidance." This quarterly report should be read in conjunction with such financial statements and notes.

In the opinion of management, all adjustments, including recurring accruals, have been made that are necessary to fairly state the consolidated financial position and results of operations and cash flows in accordance with accounting principles generally accepted in the United States of America (GAAP) for the periods covered by this quarterly report on Form 10-Q. The results of operations for the three- and nine-month periods ended September 30, 2011 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.

Certain prior year reclassifications have been made to conform to the current year financial statement presentation pertaining to immaterial items.

The December 31, 2010 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP.


Cash Equivalents

Cash equivalents included money market funds totaling $979 million and $813 million at September 30, 2011 and December 31, 2010, respectively. The carrying value of cash equivalents equals the fair value as all investments have maturities of less than three months.


Inventory

Inventory is stated at the lower of weighted average cost or market. Inventory consisted of the following:

(in millions)
  September 30, 2011
  December 31, 2010
 
   

Coal, fuel oil and other raw materials

  $ 167   $ 163  

Spare parts, materials and supplies

    84     73

Prepaid Expenses and Other

At September 30, 2011, $78 million of U.S. Treasury grants receivable related to the Taloga wind project was included in prepaid expenses and other.


New Accounting Guidance

Accounting Guidance Adopted in 2011

Revenue—Multiple-Deliverables

The Financial Accounting Standards Board (FASB) issued amended guidance for identifying separate deliverables in a revenue-generating transaction where multiple deliverables exist, and provides guidance for allocating and recognizing revenues based on those separate deliverables. This update also requires additional disclosure related to the significant assumptions used to determine the revenue recognition of the separate deliverables. This guidance is required to be applied prospectively to new or significantly modified revenue arrangements. EME adopted this guidance effective January 1, 2011. The adoption of this accounting standards update did not have a material impact on EME's consolidated results of operations, financial position or cash flows.


Fair Value Measurements and Disclosures

The FASB issued an accounting standards update modifying the disclosure requirements related to fair value measurements. Under these requirements, purchases and settlements for Level 3 fair value measurements are presented on a gross basis, rather than net. EME adopted this guidance effective January 1, 2011.


Accounting Guidance Not Yet Adopted

Fair Value Measurement

In May 2011, the FASB issued an accounting standards update modifying the fair value measurement and disclosure guidance. This guidance prohibits grouping of financial instruments for purposes of fair value measurement and requires the value be based on the individual security. This amendment also results in new disclosures primarily related to Level 3 measurements including quantitative disclosure about unobservable inputs and assumptions, a description of the valuation processes and a narrative description of the sensitivity of the fair value to changes in unobservable inputs. EME will adopt this guidance effective January 1, 2012 and does not expect the adoption of this standard will have a material impact on EME's consolidated results of operations, financial position or cash flows.


Presentation of Comprehensive Income

In June 2011, the FASB issued an accounting standards update on the presentation of comprehensive income. An entity can elect to present items of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate but consecutive statements. EME will adopt this guidance effective January 1, 2012. EME currently presents the statement of comprehensive income immediately following the statement of income and expects to continue to do so. The adoption of this accounting standards update does not change the items that constitute net income and other comprehensive income.

Note 3. Variable Interest Entities

Projects or Entities that are Consolidated

At September 30, 2011 and December 31, 2010, EME consolidated 13 and 14 projects, respectively, with a total generating capacity of 570 MW and 580 MW, respectively, that have interests held by others. In April 2011, EME sold its 75% ownership interest in a Minnesota wind project. In determining that EME was the primary beneficiary, the key factors considered were EME's ability to direct commercial and operating activities, and EME's obligation to absorb losses and right to receive benefits that could potentially be significant to the variable interest entities. Commercial and operating activities include construction, operation and maintenance, fuel procurement, dispatch and compliance with regulatory and contractual requirements.

The following table presents summarized financial information of the projects that were consolidated by EME:

(in millions)
  September 30, 2011
  December 31, 2010
 
   

Current assets

  $ 40   $ 26  

Net property, plant and equipment

    702     739  

Other long-term assets

    6     6  
       
 

Total assets

  $ 748   $ 771  
       

Current liabilities

    21     21  
       
 

Total liabilities

  $ 185   $ 188  
       

Noncontrolling interests

  $ 2   $ 4  
   

At September 30, 2011 and December 31, 2010, assets serving as collateral for the debt obligations had a carrying value of $160 million and $163 million, respectively, and primarily consist of property, plant and equipment.


Projects that are not Consolidated

EME accounts for domestic gas and wind energy projects in which it has less than a 100% ownership interest, and cannot exercise unilateral control, under the equity method. At September 30, 2011 and December 31, 2010, EME had five significant variable interests in natural gas projects that are not consolidated, consisting of the Big 4 projects (Kern River, Midway-Sunset, Sycamore and Watson) and the Sunrise project. A subsidiary of EME operates three of the four Big 4 projects and the Sunrise project and EME's partner provides the fuel management services for the Big 4 projects. In addition, the executive director of these projects is provided by EME's partner. Commercial and operating activities are jointly controlled by a management committee of each variable interest entity. Accordingly, EME accounts for its variable interests under the equity method.

EME accounts for its interest in three renewable wind generating facilities under the equity method. At December 31, 2010, EME had interests in two renewable wind generating facilities, the Elkhorn Ridge and San Juan Mesa projects. In addition to these two projects, at September 30, 2011, EME had

9


Table of Contents


interests in Community Wind North, which achieved commercial operation on May 28, 2011. The commercial and operating activities of these entities are jointly directed by representatives of each partner. Thus, EME is not the primary beneficiary of these projects.

The following table presents the carrying amount of EME's investments in unconsolidated variable interest entities and the maximum exposure to loss for each investment:

 
  September 30, 2011  
(in millions)
  Investment
  Maximum Exposure
 
   

Natural gas-fired projects

  $ 340   $ 340  

Renewable energy projects

    228     228  
   

EME's maximum exposure to loss in its variable interest entities accounted for under the equity method is generally limited to its investment in these entities. One of EME's domestic energy projects has long-term debt that is secured by a pledge of project entity assets, but does not provide for recourse to EME. Accordingly, a default under the project financing could result in foreclosure on the assets of the project entity resulting in a loss of some or all of EME's investment, but would not require EME to contribute additional capital. At September 30, 2011, entities which EME has accounted for under the equity method had indebtedness of $64 million, of which $16 million is proportionate to EME's ownership interest in this one project.


Note 4. Fair Value Measurements

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 a liability should consider assumptions that market participants would use in pricing the asset or liability, including assumptions about nonperformance risk. The fair value of derivative assets' nonperformance risk was not material as of September 30, 2011 and December 31, 2010.

EME categorizes financial assets and liabilities into a fair value hierarchy based on valuation inputs used to derive 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).

EME determines the fair value of transfers in and transfers out of each level at the end of each reporting period. There were no significant transfers between levels during the three months and nine months ended September 30, 2011 and 2010.


Valuation Techniques used to Determine Fair Value

Level 1

Level 1 includes financial assets and liabilities where unadjusted quoted prices in active markets are available at the measurement date for identical assets and liabilities. Financial assets and liabilities classified as Level 1 include exchange-traded derivatives and money market funds.


Level 2

Level 2 pricing inputs include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the derivative instrument. Financial assets and liabilities utilizing Level 2 inputs include over-the-counter derivatives.

Derivative contracts that are over-the-counter traded are valued using pricing models and are generally classified as Level 2. 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. Forward market prices are developed based on the source that best represents trade activity in each market. Broker quotes or prices from exchanges are used to validate and corroborate the primary 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. Broker quotes are incorporated when corroborated with other information which may include a combination of prices from exchanges, other brokers, and comparison to executed trades.

12


Table of Contents


Level 3

Level 3 includes financial assets and liabilities where fair value is determined using techniques that require significant unobservable inputs. Over-the-counter options, bilateral contracts, capacity contracts, qualifying facilities contracts, derivative contracts that trade infrequently (such as congestion revenue rights in the California market, financial transmission rights traded in markets outside California), long-term power agreements, and derivative contracts with counterparties that have significant nonperformance risks are classified as Level 3. In circumstances where EME cannot verify fair value with observable market transactions, it is possible that a different valuation model could produce a materially different estimate of fair value. As markets continue to develop and more pricing information becomes available, EME continues to assess valuation methodologies used to determine fair value.

For derivative contracts that trade infrequently (illiquid financial transmission rights and congestion revenue rights), changes in fair value are based on the hypothetical sale of illiquid positions. Objective criteria are reviewed, including system congestion and other underlying drivers and fair value is adjusted when it is concluded that a change in objective criteria would result in a new valuation that better reflects fair value. For illiquid long-term power agreements, fair value is based upon a discounting of future electricity and natural gas prices derived from a proprietary model using the risk free discount rate for a similar duration contract, adjusted for credit risk and market liquidity. Changes in fair value are based on changes to forward market prices, including forecasted prices for illiquid forward periods. The fair value of the majority of EME's derivatives that are classified as Level 3 is determined using uncorroborated non-binding broker quotes and models that may require EME to extrapolate short-term observable inputs in order to calculate fair value. Broker quotes are obtained from several brokers and compared against each other for reasonableness.


Long-term Debt

The carrying amounts and fair values of EME's long-term debt were as follows:

 
  September 30, 2011   December 31, 2010  
(in millions)
  Carrying
Amount

  Fair Value

Amount

  Fair Value
 
   

Long-term debt, including current portion

  $ 4,626   $ 3,274   $ 4,390   $ 3,670  
   

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 carrying amount of short-term debt approximates fair value.


Note 5. Debt and Credit Agreements

Project Financings

Walnut Creek

On July 27, 2011, EME completed, through wholly owned subsidiaries, non-recourse financings to fund construction of the Walnut Creek project, a 479 MW natural gas-fired peaker plant in southern California. The financings included floating rate construction loans totaling $495 million that will

13


Table of Contents


convert to 10-year amortizing term loans by June 30, 2013, subject to meeting specified conditions, and also included $122 million of letter of credit ($40 million outstanding at September 30, 2011) and working capital facilities.

The non-recourse financings were completed in two parts. A construction plus term loan financing of $442 million that initially accrues interest at the London Interbank Offered Rate (LIBOR) plus 2.25% and increases by 0.25% after the third, sixth and ninth anniversaries of the term conversion date. An interest rate swap agreement for a portion of the construction loan fixed the floating rate at 0.8135% beginning November 30, 2011 through May 31, 2013. The effective rate for the outstanding loan of $44 million was 2.48% at September 30, 2011. Under the swap agreement for majority of the term loan, the fixed interest rate will be 3.5429% beginning June 28, 2013 through May 31, 2023 and the effective rate is expected to be 5.84%.

A second construction plus term loan financing of $53 million was obtained by a holding company that accrues interest at LIBOR plus 4.00% over the entire term. An interest rate swap agreement for a portion of the construction loan fixed the floating rate at 0.79% beginning July 29, 2011 through May 31, 2013. The effective rate for the outstanding loan of $49 million was 4.94% at September 30, 2011. Under the swap agreement for the majority of the term loan, the fixed interest rate will be 4.0025% beginning June 28, 2013 through May 31, 2023 and the effective rate is expected to be 8.00%. Both outstanding loans were recorded in long-term debt on EME's consolidated balance sheet at September 30, 2011.

In May 2011, EME purchased, through wholly owned subsidiaries, select equipment at AES Southland Funding, LLC and its affiliates' (AES's) Huntington Beach facilities and leased such equipment back to an AES affiliate until its planned decommissioning at the end of 2012 for which AES retained the asset retirement obligation. The transaction resulted in an exemption for 90% of emission reduction credits needed to complete permitting activities for the Walnut Creek project. The $56 million of notes payable for the purchase was paid in July 2011.


Viento Funding II Wind Financing Amendment

In February 2011, EME completed, through its subsidiary, Viento Funding II, Inc., an amendment of its 2009 non-recourse financing of its interests in the Wildorado, San Juan Mesa and Elkhorn Ridge wind projects. The amendment increased the financing amount to $255 million, which included a $227 million ten-year term loan (expiring in December 2020), a $23 million seven-year letter of credit facility and a $5 million seven-year working capital facility. At September 30, 2011, $216 million was outstanding under this loan. The amount of outstanding letters of credit was $23 million. Interest under the term loan accrues at LIBOR plus 2.75% initially with the rate increasing 0.25% on every fourth anniversary. Viento Funding II, Inc. entered into interest rate swap agreements at 3.415% to hedge the majority of the variable interest rate under the term loan. Approximately $84 million under the swap agreements entered in connection with the 2009 financing were left unchanged at 3.175% and were outstanding at September 30, 2011. The effective interest rate as of September 30, 2011 was 5.77%. For further details regarding the interest rate swap agreements, see Note 6—Derivative Instruments and Hedging Activities. In conjunction with the foregoing, EME expensed $3 million of deferred financing costs and incurred a loss of $2 million from the termination of interest rate swaps, included as part of interest expense on the consolidated statement of operations.


Standby Letters of Credit

At September 30, 2011, standby letters of credit under EME's credit facility aggregated $65 million and were scheduled to expire as follows: $1 million in 2011 and $64 million in 2012. In addition, letters of

14


Table of Contents


credit under EME's subsidiaries' credit facilities aggregated $98 million and were scheduled to expire as follows: $7 million in 2011, $63 million in 2012, $10 million in 2017, and $18 million in 2018. EME's subsidiaries' aggregate amount includes $3 million issued under the Midwest Generation, LLC (Midwest Generation) credit facility and $40 million issued in connection with the power purchase agreement with Southern California Edison Company, an affiliate of EME, under the Walnut Creek credit facility. Certain letters of credit are subject to automatic annual renewal provisions.


Note 6. Derivative Instruments and Hedging Activities

EME uses derivative instruments to reduce its exposure to market risks that 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. The derivative financial instruments vary in duration, ranging from a few days to several years, depending upon the instrument. To the extent that EME does 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 consolidated balance sheets with offsetting changes recorded on the consolidated statements of operations. For derivative instruments that qualify for hedge accounting treatment, the fair value is recognized, to the extent effective, on EME's consolidated balance sheets with offsetting changes in fair value recognized in accumulated other comprehensive loss until the related forecasted transaction occurs. 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 for trading purposes are measured at fair value and included on the consolidated balance sheets as derivative assets or liabilities. Changes in fair value are recognized in operating revenues on the consolidated statements of operations.

Where EME's derivative instruments are subject to a master netting agreement 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 hedge products include forward and futures contracts that qualify for hedge accounting. This category excludes power contracts for the coal plants which meet the normal purchases and sales exception and are accounted for on the accrual method.

2
EME's hedge transactions for capacity result from bilateral trades. Capacity sold in the PJM Reliability Pricing Model (RPM) auction is not accounted for as a derivative.

3
EME also entered into transactions that adjust financial and physical positions, or day-ahead and real-time positions to reduce costs or increase gross margin. These positions largely offset each other. The net sales positions of these categories are primarily related to hedge transactions that are not designated as cash flow hedges.

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.

The portion of a cash flow hedge that does not offset the change in the value of the transaction being hedged, which is commonly referred to as the ineffective portion, is immediately recognized in earnings. EME recorded net gains of $4 million during each of the third quarters of 2011 and 2010 and $6 million and $5 million during the nine months ended September 30, 2011 and 2010, respectively, in operating revenues on the consolidated statements of operations representing the amount of cash flow hedge ineffectiveness.

Contingent Features

Certain derivative instruments contain margin and collateral deposit requirements. Since EME's and its subsidiaries' 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. Future increases in power prices could expose EME, Midwest Generation or Edison Mission Marketing & Trading, Inc. (EMMT) to additional collateral postings.


Margin and Collateral Deposits

Margin and collateral deposits include cash deposited with counterparties and brokers as credit support under energy contracts. The amount of margin and collateral deposits generally varies based on changes in fair value of the related positions. EME nets counterparty receivables and payables where balances exist under master netting arrangements. EME presents the portion of its margin and cash collateral deposits netted with its derivative positions on its consolidated balance sheets.

Accounting for Uncertainty in Income Taxes

Authoritative guidance related to accounting for uncertainty in income taxes requires an enterprise to recognize, in its financial statements, the best estimate of the impact of a tax position by determining if the weight of the available evidence indicates it is more likely than not, based solely on the technical merits, that the position will be sustained upon examination. The guidance requires the disclosure of all unrecognized tax benefits, which includes both the reserves recorded for tax positions on filed tax returns and the unrecognized portion of affirmative claims.


Unrecognized Tax Benefits

There was no change in unrecognized tax benefits from December 31, 2010. As of September 30, 2011 and December 31, 2010, $148 million of the unrecognized tax benefits, if recognized, would impact the effective tax rate.

Edison International's federal income tax returns and California combined franchise tax returns are currently open for years subsequent to 2002. In addition, specific California refund claims made by Edison International for years 1991 through 2002 remain subject to audit.

Table of Contents

The Internal Revenue Service examination phase of tax years 2003 through 2006 was completed in the fourth quarter of 2010, which included a proposed adjustment related to EME. The EME-related 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 $191 million, including interest and penalties through September 30, 2011 (the Internal Revenue Service has asserted a 40% penalty for understatement of tax liability related to this matter). Edison International disagrees with the proposed adjustment and filed a protest with the Internal Revenue Service in the first quarter of 2011. The disputed tax matter is currently being considered in appeals.


Accrued Interest and Penalties

The total amount of accrued interest and penalties related to EME's income tax liabilities was $41 million and $32 million as of September 30, 2011 and December 31, 2010, respectively.

The net after-tax interest expense (income) and penalties recognized in income tax expense was $3 million and $16 million for the three months ended September 30, 2011 and 2010, respectively, and $6 million and $10 million for the nine months ended September 30, 2011 and 2010, respectively.


Bonus Depreciation Impact on EME

The Small Business Jobs Act of 2010 and the Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act of 2010 (2010 Tax Relief Act) extended 50% bonus depreciation for qualifying property through 2012 and created a new 100% bonus depreciation for qualifying property placed in service between September 9, 2010 and December 31, 2011. These provisions are expected to result in a consolidated Edison International net operating loss for federal income tax purposes for 2011, and delay tax-allocation payments to EME until tax benefits are fully utilized by Edison International on a consolidated basis, which may take several years. In August 2011, EME received tax-allocation payments of $182 million as a result of the carryback of Edison International consolidated net operating losses for 2010. However, EME expects to make tax-allocation payments to Edison International during 2012 as a result of the reallocation of tax obligations from an expected Edison International consolidated net operating loss in 2011.

Note 9. Commitments and Contingencies

Commitments

Fuel Supply Contracts and Coal Transportation Agreements

At September 30, 2011, Midwest Generation and EME Homer City Generation L.P. (Homer City) had commitments to purchase coal from third-party suppliers at fixed prices, subject to adjustment clauses. These commitments, together with estimated transportation costs under existing agreements, are estimated to aggregate $925 million, which consists of: $245 million for the remainder of 2011, $332 million in 2012, $198 million in 2013, and $150 million in 2014.


Turbine Commitments

Based upon a June 2011 contract amendment, EME was required to schedule turbine deliveries by September 2011 or incur a termination obligation equal to its turbine deposit of $29 million. Under the terms of a September 2011 contract amendment, EME scheduled turbine deliveries for the Broken Bow I wind project which will utilize the $29 million turbine deposit. In October 2011, EME entered into a contractual agreement for the purchase of additional turbines with commitments of $39 million through 2012 for the Crofton Bluffs wind project.

22


Table of Contents

On October 8, 2010, an agreement was reached to settle disputes included in the complaint filed by EME against Mitsubishi Power Systems Americas, Inc. and Mitsubishi Heavy Industries, Ltd. with respect to a wind turbine generator supply agreement. As a result of this agreement, EME may elect to deploy up to 60 additional wind turbines (aggregating 144 MW) that were part of the original contract, or may be obligated to make a payment of up to $30 million following the end of the three-year period, which commenced on October 8, 2010, if it has not elected to deploy the additional turbines and if certain other criteria apply.


Capital Commitments

At September 30, 2011, EME's subsidiaries had firm commitments to spend approximately $157 million during the remainder of 2011, $235 million in 2012 and $19 million in 2013 for capital expenditures. These expenditures primarily relate to the Walnut Creek project and the construction of wind projects. EME intends to fund these expenditures through project level financing, U.S. Treasury grants, Midwest Generation and EME lines of credit, if available, cash on hand and cash generated from operations.


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 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 sale-leaseback transaction related to the Powerton and Joliet Stations in Illinois, EME agreed to indemnify the 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." Except as discussed below, EME has 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, it has been extended until February 2012. There were approximately 230 cases for which Midwest Generation was potentially liable that had not been settled and dismissed

23


Table of Contents


at September 30, 2011. Midwest Generation had recorded a liability of $55 million at September 30, 2011 related to this contractual indemnity.

The amounts recorded by Midwest Generation for the asbestos-related liability are based upon a number of assumptions. Future events, such as the number of new claims to be filed each year, the average cost of disposing of claims, as well as the numerous uncertainties surrounding asbestos litigation in the United States, could cause the actual costs to be higher or lower than projected.


Environmental Indemnity Related to the Homer City Plant

In connection with the acquisition of the Homer City plant, Homer City agreed to indemnify the sellers with respect to specified environmental liabilities before and after the date of sale. EME guaranteed this obligation of Homer City. Also, in connection with the sale-leaseback transaction related to the Homer City plant, Homer City agreed to indemnify the lessors for specified environmental liabilities. Due to the nature of the obligations under these indemnity provisions, they are not subject to a maximum potential liability and do not have expiration dates. 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."


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 September 30, 2011, EME had recorded a liability of $43 million related to these matters.

In connection with the sale of various domestic assets, EME has from time to time provided indemnities to the purchasers for taxes imposed with respect to operations of the assets prior to the sale. EME has also provided indemnities to purchasers for items specified in each agreement (for example, specific pre-existing litigation matters and/or environmental conditions). Not all indemnities under the asset sale agreements have specific expiration dates. Due to the nature of these potential obligations, a maximum potential liability cannot be determined and has not been recorded as a liability related to these indemnities.

In connection with the sale-leaseback transactions related to the Homer City plant in Pennsylvania, the Powerton and Joliet Stations in Illinois and, previously, the Collins Station in Illinois, EME and several of its subsidiaries entered into tax indemnity agreements. Under these tax indemnity agreements, the lessees in the sale-leaseback transactions agreed to indemnify the 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 sale-leaseback transactions related to the Powerton and Joliet Stations in Illinois. The potential indemnity obligations under these tax indemnity agreements could be significant. Due to the nature of these potential obligations, EME cannot determine a maximum potential liability which would be triggered by a valid claim from the lessors. EME has not recorded a liability for these matters.

24


Table of Contents

EME agreed to indemnify the lessors in the sale-leaseback transaction related to the Homer City plant for certain negative federal income tax consequences should the rent payments be "levelized" for tax purposes and for potential foreign tax credit losses in the event that the lessor's debt is characterized as recourse, rather than non-recourse. This indemnity covers a limited range of possible tax consequences that are unrelated to performance under the lease.


Other Indemnities

EME provides 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 obligations under these agreements may or may not be limited in terms of time and/or amount, and in some instances EME may have recourse against third parties. EME has not recorded a liability related to these indemnities. The overall maximum amount of the obligations under these indemnifications cannot be reasonably estimated.


Contingencies

In addition to the matters disclosed in these notes, EME is involved in other legal, tax and regulatory proceedings before various courts and governmental agencies regarding matters arising in the ordinary course of business. EME believes the outcome of these other proceedings will not materially affect its 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 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 calls for an injunction ordering Midwest Generation to install controls sufficient to meet BACT emission rates at all units subject to the complaint; to obtain new PSD or New Source Review permits for those units; to amend its applications under Title V of the CAA; to conduct audits of its operations to determine whether any additional modifications have occurred; and to offset and mitigate the harm to public health and the environment caused by the alleged CAA violations. 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 have intervened in the case.

Nine of ten PSD claims 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. The court has also dismissed 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. Trial of the liability portion of the case is scheduled to commence June 3, 2013. A motion

25


Table of Contents


filed by the plaintiffs requesting that the dismissals be certified as "partial final judgments" capable of appeal, and requesting that the remaining claims be stayed pending such an appeal, is pending.

In May 2011, two complaints were filed against Midwest Generation in the Northern District of Illinois by residents living near the Crawford and Fisk facilities on behalf of themselves and all others similarly situated, each asserting claims of nuisance, negligence, trespass, and strict liability. The plaintiffs sought to have their suits certified as a class action and requested injunctive relief, as well as compensatory and punitive damages. In October 2011, the complaints were dismissed for lack of federal jurisdiction. EME does not know whether the plaintiffs will appeal the dismissal or file a complaint in state court.

Adverse decisions in these cases could involve penalties and remedial actions 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 its and Midwest Generation's results of operations, financial position or cash flows.


Homer City New Source Review and Other Litigation

In January 2011, the US EPA filed a complaint in 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 Pennsylvania Department of Environmental Protection, the State of New York and the State of New Jersey intervened in the lawsuit.

Also in January 2011, two residents filed a complaint in 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 Edison International, 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.

On October 12, 2011, all of the claims in the US EPA's lawsuit were dismissed with prejudice. On October 13, 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 US EPA and the other plaintiffs in these cases will appeal the dismissal of these cases, or whether plaintiffs in the purported class action lawsuit will file a complaint in state court. If the plaintiffs are able to revive the lawsuits, 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 Homer City and EME.


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 subsidiaries' existing facilities and affect the timing, cost, location, design,

26


Table of Contents


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, commonly referred to as CERCLA, or similar laws for the investigation and remediation of contaminated property, EME accrues a liability to the extent the costs are probable and can be reasonably estimated. Midwest Generation had accrued approximately $10 million at September 30, 2011 for estimated environmental investigation and remediation costs for 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. 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 cannot be certain that the existence or extent of all contamination at its sites has been fully identified.


Note 10. Environmental Developments

Cross-State Air Pollution Rule

On July 6, 2011, the US EPA adopted the Cross-State Air Pollution Rule (CSAPR). CSAPR is the final form of a previously proposed replacement for the Clean Air Interstate Rule (CAIR), originally called the Clean Air Transport Rule that was released in 2010. CSAPR establishes emissions reductions for annual sulfur dioxide (SO2) emissions and annual and ozone season nitrogen oxide (NOx) emissions in two phases: a first phase effective January 1, 2012 and, in most states subject to the program (including Illinois and Pennsylvania), a second phase effective January 1, 2014 that requires additional reductions in annual SO2 emissions.

CSAPR, like the CAIR, is an allowance-based regulation that provides for emissions trading. Under CSAPR, the amount of actual SO2 or NOx emissions from operations will need to be matched by a sufficient amount of SO2 or NOx allowances that are either allocated or purchased in the open market. In connection with CSAPR, the US EPA has, for each phase, established SO2 and NOx allowance allocations for each state and each generating unit subject to the regulation, and at the close of the annual or seasonal compliance period, units must surrender allowances for each ton of SO2 and NOx emitted or face penalties. While trading of allowances is permitted within designated groups of states, the rule provides for penalties against a unit with emissions in excess of its predefined "assurance level," but only if the state in which it is located also exceeds its budgeted emissions level. On October 6, 2011, the US EPA announced a proposed revision to the rule that would effectively eliminate such penalties in the first phase.

EME believes that Midwest Generation's current environmental remediation plan developed to comply with the CPS, along with the allowances allocated to it under CSAPR, will be sufficient to comply with the requirements of CSAPR and the US EPA's proposed regulation on hazardous air pollutant (HAP) emissions. In order to achieve compliance, Midwest Generation has begun work to install SO2 controls at certain of its plants.

The SO2 allowances allocated to Homer City in CSAPR Phase I (25,797 tons in 2012 and 2013) are significantly lower than the amount that would be required based on Homer City's historical emissions (2010 SO2 emissions were 112,951 tons). Therefore, pending installation of additional equipment for Units 1 and 2 (Homer City's Unit 3 is equipped with a wet scrubber flue gas desulfurization system to meet environmental standards), Homer City expects that it will be required to procure additional

27


Table of Contents

allowances. It is unclear at this time whether Homer City will be able to acquire allowances for 2012 and 2013 in sufficient quantity to cover its normal operations and whether it will be able to pass through the cost of such allowances in the marketplace. Also, Homer City's SO2 emissions could exceed its assurance level, and, therefore, unless the US EPA's proposed revision to the rule is adopted, Homer City could be subject to penalties depending on whether, collectively, emissions from all of the subject electrical generating facilities in Pennsylvania exceed the state's budgeted emissions level. Accordingly, Homer City is evaluating alternative options, including reduced dispatch and fuel modifications, for complying with Phase I of CSAPR. The cost of allowances, together with possible operational impacts or reductions of output that may be required to comply with Phase I of CSAPR, could have a material effect on Homer City.

Homer City has begun work on designing SO2 and particulate emissions control equipment for Units 1 and 2. While the Phase II SO2 emission allowances under CSAPR (11,068 tons) are less than were contemplated under the proposed Clean Air Transport Rule, the additional reductions are not expected to materially change the design for the SO2 controls at Units 1 and 2. The installation of those SO2 controls will require capital commitments for the Homer City plant well in advance of the 2014 effective date, including some expenditures in 2011, in order to meet regulatory deadlines. Given the relatively short period of time before Phase II of CSAPR takes effect in 2014, there is no assurance that Homer City will be able to complete all the work that will be required before the deadline. Homer City is continuing to review technologies available to reduce SO2 and mercury emissions; however, it has not determined the most effective and efficient technology to meet all requirements that may be imposed on it. Consequently, the timing, selection of technology and ultimate capital costs remain uncertain. Based on preliminary estimates, Homer City currently believes the cost of such equipment may be between $600 million and $700 million. An application for a construction permit to install the additional controls was filed on October 3, 2011 with the Pennsylvania Department of Environmental Protection.

Homer City does not currently have sufficient capital and does not expect to generate sufficient funds from operations to complete such retrofits and will have to seek third-party financing, which will be subject to decisions by Homer City's lessors, holders of bonds who provided financing for the sale-leaseback transaction and new providers of capital funding. There is no assurance that sufficient financing will be obtained or will not result in significant dilution of Homer City's interest in the Homer City plant.

In July 2011, EME asked the US EPA to stay the effectiveness of CSAPR pending judicial review, and in October 2011, Homer City asked the US EPA to reconsider the rule. In August 2011, Homer City asked the United States Court of Appeals for the District of Columbia to review CSAPR and requested a stay of the rule while its motion is pending. Numerous similar challenges have been filed by other industry participants and by several states.


Proposed Hazardous Air Pollutant Regulations

In March 2011, the US EPA proposed National Emission Standards for Hazardous Air Pollutants, limiting emissions of HAPs from coal- and oil-fired electrical generating units. This regulation is expected to be finalized by December 2011. Based on its continuing review, EME does not expect that these standards, if adopted as proposed, would require Midwest Generation to make material changes to the approach to compliance with state and federal environmental regulations that it contemplates for CPS compliance. EME also does not expect that these standards, if adopted as proposed, would require Homer City to make additional capital requirements beyond those that would be required to comply with CSAPR.

Ozone and Particulates

In September 2011, President Obama announced that the proposed revision to the National Ambient Air Quality Standards (NAAQS) for ozone, which was expected to have set a more stringent standard for primary ozone and a distinct secondary standard to protect sensitive vegetation and ecosystems, was being withdrawn. The ozone NAAQS established in 2008 remains in place, but the implementation process must be completed before the 0.075 parts-per-million standard can be enforced. The US EPA has indicated that it intends to issue initial area designations of attainment, nonattainment, and unclassifiable areas across the nation in 2012. States will then be required develop and submit state implementation plans outlining how compliance with the 2008 NAAQS will be achieved. New primary and secondary ozone standards are expected in 2014.


Water Quality—Clean Water Act

In March 2011, the US EPA proposed standards under the federal Clean Water Act which would affect cooling water intake structures at generating facilities. The standards are intended to protect aquatic organisms by reducing capture in screens attached to cooling water intake structures (impingement) and in the water volume brought into the facilities (entrainment). The regulations are expected to be finalized by July 2012. EME is evaluating the proposed standards and believes, from a preliminary review, that compliance with the proposed standards regarding impingement will be achievable for both the Midwest Generation plants and the Homer City plant without incurring material additional capital expenditures or operating costs. The required measures to comply with the proposed standards regarding entrainment are subject to the discretion of the permitting authority, and EME is unable at this time to assess potential costs of compliance, which could be significant for the Midwest Generation plants, but are not expected to be material for the Homer City plant, which already has cooling towers.


Greenhouse Gas Litigation Developments

In June 2011, the U.S. Supreme Court dismissed public nuisance claims against five power companies, ruling that the CAA and the US EPA actions it authorizes displace federal common law nuisance claims that might arise from of the emission of greenhouse gases. The court also affirmed the Second Circuit's determination that at least some of the plaintiffs had standing to bring the case. The court did not address whether the CAA also preempts state law claims arising from the same circumstances.

Parties to the case brought by the Alaskan Native Village of Kivalina against Edison International and other defendants, the appeal of which was deferred before the Ninth Circuit Court of Appeals pending the Supreme Court's ruling described above, have requested that the appeal recommence and have asked for permission to file additional briefs on the impact of the Supreme Court's ruling. The stay of the appeal has now been lifted and argument before the Ninth Circuit is scheduled for November 2011. Kivalina is seeking damages of up to $400 million for the cost of relocating the village.

On May 27, 2011, private citizens filed a purported class action complaint in the United States District Court for the Southern District of Mississippi, naming among a large number of defendants, Edison International, EME, and three wholly owned subsidiaries of EME (Edison Mission Energy Fuel, Edison Mission Energy Petroleum, and Edison Mission Energy Services). Plaintiffs allege that the defendants' activities resulted in emissions of substantial quantities of greenhouse gases that have contributed to climate change and sea level rise, which in turn are alleged to have increased the destructive force of Hurricane Katrina. The lawsuit alleges causes of action for negligence, public and private nuisance, and trespass, and seeks unspecified compensatory and punitive damages. The claims in this lawsuit are nearly identical to a subset of the claims that were raised against many of the same defendants in a previous lawsuit that was filed in, and dismissed by, the same federal district court where the current

case has been filed. Edison International was dismissed as a defendant in this complaint in July 2011, but EME and the three subsidiaries remain defendants.

Included in accumulated other comprehensive loss at September 30, 2011 was $10 million, net of tax, of unrealized gains on commodity-based cash flow hedges; and $49 million, net of tax, of unrealized losses related to interest rate hedges. The maximum period over which a commodity cash flow hedge is designated is May 31, 2014.

Unrealized gains on commodity hedges consist of futures and forward electricity contracts that qualify for hedge accounting. These gains arise because current forecasts of future electricity prices in these markets are lower than the contract prices. Approximately $11 million of unrealized gains 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 gains will increase 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.

MANAGEMENT'S OVERVIEW

Introduction

EME's competitive power generation business primarily consists of the generation and sale into the PJM market on a merchant basis of energy and capacity from its approximately 7,000 megawatts of coal-fired power plants and sales from its primarily contracted renewable projects. The profitability of the coal operations has been significantly lower in 2011 compared to 2010 as a result of lower realized energy prices at the Midwest Generation plants, higher fuel costs and outages at the Homer City plant. In addition, the profitability of EME's Midwest Generation plants is expected to be adversely affected by a decline in capacity prices and higher rail transportation costs (due to the expiration at the end of 2011 of a favorable long-term rail contract), and EME's Homer City plant may be adversely impacted by new environmental regulations discussed further below. For discussion of energy and fuel price risks, see "Market Risk Exposures—Commodity Price Risk" and refer to "Market Risks" in Item 1A on page 33 of EME's annual report on Form 10-K for the year ended December 31, 2010. As a result, EME may incur net losses during 2011 and in subsequent years unless energy and capacity prices increase or its costs decline.

Table of Contents

EME's third quarter 2011 core earnings were lower than third quarter 2010 core earnings primarily due to the following pre-tax items:

$81 million decrease in Midwest Generation adjusted operating income primarily due to lower capacity revenues, average realized energy prices and generation, and a gain in 2010 from the sale of bankruptcy claims against Lehman.

$22 million decrease in Homer City adjusted operating income primarily due to lower capacity revenues and higher coal costs.

$17 million increase in interest expense due to higher interest related to the new energy projects financings in 2011 of $6 million and lower capitalized interest of $11 million.

$16 million decrease in energy trading revenues partially due to reduced revenues from power trading activities. The decrease is also partially due to the allocation to Homer City the benefit of an arrangement that allows EMMT to deliver power into the NYISO from Homer City. However, such decrease resulting from that allocation is offset by the increase recognized at Homer City due to the arrangement.

$10 million decrease in renewable energy adjusted operating income primarily due to lower capacity factors driven by wind conditions.

EME's core earnings for the nine months ended September 30, 2011 were lower than core earnings for the nine months ended September 30, 2010 primarily due to the following pre-tax items:

$126 million decrease in Midwest Generation adjusted operating income primarily due to lower average realized energy prices and generation, and a gain in 2010 from the sale of bankruptcy claims against Lehman.

$85 million decrease in Homer City adjusted operating income primarily due to lower energy revenues driven by lower generation, lower capacity revenues and higher plant maintenance costs from outages. Partially offsetting the decrease were unrealized derivative gains of $3 million in 2011 compared to losses of $13 million in 2010.

$43 million increase in interest expense due to higher interest expense primarily related to the new energy projects financings in 2011 of $25 million and lower capitalized interest of $18 million.

$38 million decrease in energy trading revenue partially due to reduced revenues from power trading activities. The decrease is also partially due to the allocation to Homer City the benefit of an arrangement that allows EMMT to deliver power into the NYISO from Homer City. However, such decrease resulting from that allocation is offset by the increase recognized at Homer City due to the arrangement.

$12 million decrease in adjusted operating income from the Big 4 projects due to lower capacity prices under Midway-Sunset's new power purchase agreement and lower capacity and energy sales margin.

These decreases were partially offset by the following:

$11 million higher income from a distribution received from the Doga project in 2011, compared to 2010.

$6 million increase in renewable energy adjusted operating income due to the increase in wind projects in operation coupled with higher generation, partially offset by lower realized energy prices at the merchant wind projects.

Non-core item for EME included:

An earnings benefit of $16 million recorded in the nine months ended September 30, 2010 related to the acceptance by the California Franchise Tax Board of the tax positions finalized with the Internal Revenue Service in 2009 for tax years 1986 through 2002 as part of the federal settlement of tax disputes and a revision to the interest on federal disputed tax items.


Cross-State Air Pollution Rule

On July 6, 2011, the US EPA adopted the CSAPR. CSAPR is the final form of a previously proposed replacement for the CAIR, originally called the Clean Air Transport Rule that was released in 2010. CSAPR establishes emissions reductions for annual SO2 emissions and annual and ozone season NOx emissions in two phases: a first phase effective January 1, 2012 and, in most states subject to the program (including Illinois and Pennsylvania), a second phase effective January 1, 2014 that requires additional reductions in annual SO2 emissions.

CSAPR, like the CAIR, is an allowance-based regulation that provides for emissions trading. Under CSAPR, the amount of actual SO2 or NOx emissions from operations will need to be matched by a sufficient amount of SO2 or NOx allowances that are either allocated or purchased in the open market. In connection with CSAPR, the US EPA has, for each phase, established SO2 and NOx allowance allocations for each state and each generating unit subject to the regulation, and at the close of the annual or seasonal compliance period, units must surrender allowances for each ton of SO2 and NOx emitted or face penalties.

On October 6, 2011, the US EPA announced a proposed revision to the rule that would effectively eliminate such penalties in the first phase.

EME believes that Midwest Generation's current environmental remediation plan developed to comply with the CPS, along with the allowances allocated to it under CSAPR, will be sufficient to comply with the requirements of CSAPR and the US EPA's proposed regulation on HAP emissions. In order to achieve compliance, Midwest Generation has begun work to install SO2 controls at certain of its plants.

The SO2 allowances allocated to Homer City in CSAPR Phase I (25,797 tons in 2012 and 2013) are significantly lower than the amount that would be required based on Homer City's historical emissions (2010 SO2 emissions were 112,951 tons). Therefore, pending installation of additional equipment for Units 1 and 2 (Homer City's Unit 3 is equipped with a wet scrubber flue gas desulfurization system to meet environmental standards), Homer City expects that it will be required to procure additional allowances. It is unclear at this time whether Homer City will be able to acquire allowances for 2012 and 2013 in sufficient quantity to cover its normal operations and whether it will be able to pass through the cost of such allowances in the marketplace.

to materially change the design for the SO2 controls at Units 1 and 2. The installation of those SO2 controls will require capital commitments for the Homer City plant well in advance of the 2014 effective date, including some expenditures in 2011, in order to meet regulatory deadlines. Given the relatively short period of time before Phase II of CSAPR takes effect in 2014, there is no assurance that Homer City will be able to complete all the work that will be required before the deadline. Homer City is continuing to review technologies available to reduce SO2 and mercury emissions; however, it has not determined the most effective and efficient technology to meet all requirements that may be imposed on it. Consequently, the timing, selection of technology and ultimate capital costs remain uncertain. Based on preliminary estimates, Homer City currently believes the cost of such equipment may be between $600 million and $700 million. An application for a construction permit to install the additional controls was filed on October 3, 2011 with the Pennsylvania Department of Environmental Protection.


Homer City Capital Needs and Liquidity

Homer City does not currently have sufficient capital and does not expect to generate sufficient funds from operations to complete retrofits effectively required by CSAPR Phase II. EME is under no legal obligation to, and has chosen not to, provide funding. Homer City expects to fund $13 million of project costs during the remainder of 2011. However, Homer City will need third-party capital to undertake the retrofits required by 2014 under CSAPR and to fund capital costs beginning in 2012 in order to complete the requisite retrofits by early 2014. However, restrictions under the agreements entered into as part of Homer City's 2001 sale-leaseback transaction affect, and in some cases significantly limit or prohibit, Homer City's ability to incur indebtedness or make capital expenditures. Consequently, Homer City's ability to install environmental compliance equipment will be dependent on approvals by its lessors and holders of bonds who provided financing for the sale-leaseback transaction, and upon its ability to obtain new capital funding.

Homer City has engaged a financial advisor and commenced a process to obtain capital funding from third parties to install the environmental improvements. Homer City's objective is to maximize the value of its leasehold interest while obtaining the incremental capital needed to make such improvements. There can be no assurance that Homer City will be able to raise the financing necessary to install the required SO2 control equipment in a timely manner or on terms that will not result in a significant dilution of its interest in the Homer City plant. A significant dilution of interest in the Homer City plant may result in a financial statement deconsolidation of Homer City if EME no longer retains control for inclusion in the consolidated financial statements. In this event, the transaction would be accounted for as a disposition and could result in a material loss. At September 30, 2011, the book value of EME's investment in Homer City and related assets was approximately $1.1 billion.

Homer City believes that the persistence of low power prices, combined with the outages suffered earlier this year and the possible impacts of compliance with CSAPR Phase I in 2012, will make it unlikely that Homer City will meet the covenant requirements of its sale-leaseback documents relating to the payment of equity rent at April 1, 2012. Under the sale-leaseback documents, rent payments are comprised of two components, senior rent and equity rent. Senior rent is used exclusively for debt service to holders of senior secured bonds issued in connection with the sale-leaseback transaction, while equity rent is paid to the owner-lessors. In order to pay equity rent, among other requirements, Homer City must meet historical and projected senior rent service coverage ratios of 1.7 to 1 (subject to reduction to 1.3 to 1 under certain circumstances). A failure to pay equity rent does not entitle the owner-lessors to foreclose upon Homer City's leasehold interest, but it does result in the suspension of Homer City's ability to make permitted distributions. Moreover, the ability to make permitted distributions would be permanently frozen if a failure to pay equity rent when due was not cured within nine months, or even if timely cured, there occurred more than one additional failure to pay equity rent when due at any future time during the term of the lease. Homer City is not subject to any

minimum historical and projected senior rent service coverage ratios except as conditions to distributions and equity rent payments. Also, failure by Homer City to pay equity rent when due in April 2012 could trigger termination of the $47 million senior rent reserve letter of credit. Homer City would then be required to fund the senior rent reserve, and failure to do so could entitle counterparties to seek available remedies under the sale-leaseback documents, including termination or foreclosure upon the leasehold interest.

EME's subsidiary, EMMT, enters into energy and capacity transactions on behalf of Homer City pursuant to an intercompany agreement. Those transactions are generally back-to-back transactions in which EMMT enters into a transaction with a third party as a principal and then enters into an equivalent transaction with Homer City. In the case of energy sales, if Homer City fails to perform its obligations under the intercompany agreement, EMMT would seek to fulfill its third-party obligations through market transactions which may result in losses. In the case of capacity, EMMT has sold Homer City capacity in the annual PJM base residual auctions through May 2015. If Homer City were to default on its obligations to supply capacity, then EMMT would be liable to PJM to supply that capacity, and failure to do so would expose EMMT to penalties under the PJM tariffs. If one or more of the Homer City units were to be unavailable as a capacity resource and EMMT did not fulfill this obligation through market transactions, then PJM would assess a penalty against EMMT (excluding a refund of any capacity payments received by EMMT) equal to the greater of 20% of the capacity payments or $20 per MW-day.

Failure of Homer City to find an economic manner to continue plant operations, by installing the required equipment or otherwise, could result in a foreclosure on its leasehold interest and/or a curtailment of plant operations. Curtailment of plant operations or a significant reduction of the value of Homer City's interest in the plant could have an adverse effect on future financial results, cash flow, financial flexibility and assets of EME compared to historical levels.


Midwest Generation Environmental Compliance Plans and Costs

During 2011, Midwest Generation continued its permitting and planning activities for NOx and SO2 controls to meet the requirements of the CPS. Based on its continuing review, EME does not expect the US EPA's proposed National Emission Standards for Hazardous Air Pollutants, if adopted, would require Midwest Generation to make material changes to the approach to compliance with state and federal environmental regulations that it contemplates for CPS compliance. Midwest Generation expects to continue to develop and implement a compliance program that includes the use of activated carbon injection, upgrades to particulate removal systems and dry sorbent injection, combined with its use of low sulfur PRB coal, to meet emissions limits for criteria pollutants, such as NOx and SO2 as well as for HAPs, such as mercury, acid gas and non-mercury metals. Based on stack tests performed at various Midwest Generation plants, Midwest Generation believes that currently installed activated carbon injection and proposed particulate removal equipment is sufficient to achieve or exceed the mercury standards outlined in the US EPA's existing and proposed rules.

In February 2011, the Illinois Environmental Protection Agency issued construction permits authorizing Midwest Generation to install a dry sorbent injection system using Trona or other sodium-based sorbents at the Powerton Station's Units 5 and 6.

Decisions regarding whether or not to proceed with retrofitting units to comply with CPS requirements for SO2 emissions, including those that have received permits, remain subject to a number of factors, such as market conditions, regulatory and legislative developments, and forecasted commodity prices and capital and operating costs applicable at the time decisions are required or made. Midwest Generation could also elect to temporarily or permanently shut down units, instead of installing controls, to be in compliance with the CPS.

38


Table of Contents

Therefore, decisions about any particular combination of retrofits and shutdowns Midwest Generation may ultimately employ also remain subject to conditions applicable at the time decisions are required or made. Final decisions on whether to install controls, to install particular kinds of controls, and to actually expend capital or continue with the expenditure of capital that is budgeted may not occur until 2012 for some of the units and potentially later for others, subject to the requirements of the CPS and other applicable regulations. Pending such final decisions, Midwest Generation plans to continue with any work necessary to comply with issued permits.


EME's Liquidity

At September 30, 2011, EME, as a holding company, had cash and cash equivalents of $539 million to meet liquidity needs as well as $499 million of capacity under its credit facility. EME's subsidiary, EMMT, also had cash and cash equivalents of $195 million at September 30, 2011, which can be loaned or distributed to EME subject to applicable laws. In addition, at September 30, 2011, Midwest Generation had cash and cash equivalents of $333 million to meet liquidity needs as well as $497 million of capacity under its credit facility. The EME and Midwest Generation credit facilities mature in June 2012. EME may seek to extend or replace these facilities or seek other means of credit support to meet its liquidity requirements.

Midwest Generation has not yet committed to the completion of environmental compliance activities for its plants. Additional expenditures for NOx and SO2 controls through 2013 are estimated at $514 million based on an assumption that Midwest Generation would retrofit all units over the compliance period, which extends to 2018 at an estimated aggregate cost of $1.2 billion. Depending upon the facilities selected to be retrofitted, the cost of such retrofitting, and the timing of funding requirements beyond the near term, Midwest Generation may utilize operating cash flow, draw on its credit facilities to the extent these are available when funding is required, obtain funding from EME, or seek debt financing to fund capital expenditures.

Capital expenditures for various renewable energy projects for the remainder of 2011 are projected to be $92 million at September 30, 2011. EME anticipates that the capital investment for renewable energy projects under construction will be funded using a combination of construction and term financings, U.S. Treasury grants and cash on hand. EME received a total of $310 million of U.S. Treasury grants in the third quarter of 2011 and used $57 million to repay the Laredo Ridge bridge loan. Additional U.S. Treasury grants of approximately $135 million are anticipated for the remainder of 2011 and in 2012 based on estimated eligible construction costs for renewable energy projects.

Edison International's utilization of net operating losses and production tax credits from EME in its consolidated return impacts EME's liquidity. The bonus depreciation extension enacted in the Small Business Jobs Act of 2010 and the 2010 Tax Relief Act is expected to result in delays in EME's receipt of future tax-allocation payments. In August 2011, EME received tax-allocation payments of $182 million. However, EME expects to make tax-allocation payments to Edison International during 2012 as a result of the reallocation of tax obligations from an expected Edison International consolidated net operating loss in 2011. For more information, see "Edison Mission Energy and Subsidiaries Notes to Consolidated Financial Statements—Note 7. Income Taxes—Bonus Depreciation Impact on EME" and refer to "Liquidity Risks" in Item 1A on page 29 of EME's annual report on Form 10-K for the year ended December 31, 2010.

AOI is equal to operating income (loss) under GAAP, plus equity in income (loss) of unconsolidated affiliates, dividend income from projects, production tax credits, other income and expenses, and net (income) loss attributable to noncontrolling interests. Production tax credits are recognized as wind energy is generated based on a per-kilowatt-hour rate prescribed in applicable federal and state statutes. AOI is a non-GAAP performance measure and may not be comparable to those of other companies. Management believes that inclusion of earnings of unconsolidated affiliates, dividend income from projects, production tax credits, other income and expenses, and net (income) loss attributable to noncontrolling interests in AOI is meaningful for investors as these components are integral to the operating results of EME.

respectively, related to the net cost of emission allowances. Transfers of emission allowances between Midwest Generation and Homer City are made at fair market value. Transfers of NOx emission allowances to Midwest Generation were $0.4 million during each of the nine months ended September 30, 2011 and 2010. Transfers of SO2 emission allowances from Midwest Generation were none and $5 million during the nine months ended September 30, 2011 and 2010, respectively.

AOI from the Midwest Generation plants decreased $81 million for the third quarter ended September 30, 2011, compared to the corresponding period of 2010. The third quarter decrease in AOI was primarily attributable to lower energy and capacity revenues and a gain in 2010 from the sale of bankruptcy claims against Lehman. During the third quarter of 2010, EME sold its bankruptcy claims against Lehman and recorded a gain of $24 million. The decline in energy revenues was due to lower generation and lower average realized energy prices, and the decline in capacity revenues was due to lower capacity prices from the RPM auction.

AOI from the Midwest Generation plants decreased $126 million for the nine months ended September 30, 2011, compared to the corresponding period of 2010. The 2011 decrease in AOI was primarily attributable to lower energy revenues and a gain in 2010 from the sale of the bankruptcy claims discussed above. The decline in energy revenues was due to lower average realized energy prices and lower generation due to the permanent shutdown of Will County Units 1 and 2 at the end of 2010 in accordance with the CPS.

Included in operating revenues were unrealized losses from hedge activities of $3 million and $16 million for the third quarters of 2011 and 2010, respectively, and $1 million and $12 million for the nine months ended September 30, 2011 and 2010, respectively. Unrealized losses in 2011 and 2010 were primarily attributable to economic hedge contracts that are accounted for at fair value with offsetting changes recorded on the consolidated statements of operations.

Included in fuel costs were unrealized gains (losses) of $(4) million and $2 million during the third quarters of 2011 and 2010, respectively, and $(6) million and $(5) million for the nine months ended September 30, 2011 and 2010, respectively. Unrealized gains (losses) were due to oil futures contracts that were accounted for as economic hedges. These contracts were entered into in 2010 and 2009 to hedge variable fuel oil components of rail transportation costs.

AOI from the Homer City plant decreased $22 million for the third quarter ended September 30, 2011, compared to the corresponding period of 2010. The third quarter decrease in AOI was primarily attributable to lower capacity revenues and higher coal costs.

AOI from the Homer City plant decreased $85 million for nine months ended September 30, 2011, compared to the corresponding period of 2010. The 2011 decrease in AOI was attributable to lower energy revenues driven by lower generation, lower capacity revenues, and higher plant maintenance costs from outages at Units 1 and 2, partially offset by unrealized gains in 2011 compared to unrealized losses in 2010 related to hedge contracts and lower fuel costs. The decline in fuel costs was primarily due to lower generation, mostly offset by higher coal costs.

Table of Contents

Included in operating revenues were unrealized gains (losses) from hedge activities of $(2) million and $1 million for the third quarters of 2011 and 2010, respectively, and $3 million and $(13) million for the nine months ended September 30, 2011 and 2010, respectively. Unrealized gains (losses) in 2011 were attributable to both economic hedge contracts that are accounted for at fair value with offsetting changes recorded on the statements of operations and the ineffective portion of forward and futures contracts which are derivatives that qualify as cash flow hedges. Unrealized gains (losses) in 2010 were attributable to the ineffective portion of forward and futures contracts. The ineffective portion of hedge contracts at Homer City was attributable to changes in the difference between energy prices at PJM West Hub (the settlement point under forward contracts) and the energy prices at the Homer City busbar (the delivery point where power generated by the Homer City plant is delivered into the transmission system).

The average realized energy price is presented as an aid in understanding the operating results of the coal plants. Average realized energy price is a non-GAAP performance measure since such statistical measure excludes unrealized gains or losses recorded as operating revenues. Management believes that the average realized energy price is 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. A reconciliation of the operating revenues of the coal plants presented in the preceding table and renewable energy projects presented in "—Renewable Energy Projects" to consolidated operating revenues is set forth below:

Average Realized Fuel Costs

The average realized fuel costs reflect the average cost per MWh at which fuel is consumed for generation sold into the market, including emission allowance costs and the effects of hedges. It is determined by dividing (i) fuel costs adjusted for unrealized gains (losses) by (ii) generation as shown in the table below:

The average realized fuel costs are presented as an aid in understanding the operating results of the Midwest Generation plants. Average realized fuel costs are a non-GAAP performance measure since such statistical measure excludes unrealized gains or losses recorded as fuel costs. Management believes that average realized fuel costs are meaningful for investors as this information reflects the impact of

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 coal 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.


Seasonality—Coal Plants

Due to fluctuations in electric demand resulting from warm weather during the summer months and cold weather during the winter months, electric revenues from the coal 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, income from the coal plants 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."

AOI is equal to operating income (loss) under GAAP plus equity in income (loss) of unconsolidated affiliates, dividend income from projects, production tax credits, other income and expense, and net (income) loss attributable to noncontrolling interests. Production tax credits are recognized as wind energy is generated based upon a per-kilowatt-hour rate prescribed in applicable federal and state statutes. Under GAAP, production tax credits generated by wind projects are recorded as a reduction in income taxes. Accordingly, AOI represents a non-GAAP performance measure which may not be comparable to those of other companies. Management believes that inclusion of production tax credits in AOI for wind projects is meaningful for investors as federal and state subsidies are an integral part of the economics of these projects.

2
The statistics section summarizes key performance measures related to wind projects, which represents substantially all of the renewable energy projects.

3
Includes renewable energy projects that are unconsolidated at EME. Generation excluding unconsolidated projects was 819 GWh and 643 GWh in the third quarters of 2011 and 2010, respectively, and 3,356 GWh and 2,156 GWh in the nine months ended September 30, 2011 and 2010, respectively.

AOI from renewable energy projects decreased $10 million in the third quarter and increased $6 million in the nine months ended September 30, 2011, compared to the corresponding periods of 2010. The decrease in the third quarter was primarily due to lower capacity factors driven by wind conditions. The year-to-date increase was primarily due to projects that achieved commercial operation in late 2010 and 2011 and increased generation at other projects due to higher availability and favorable wind conditions during the first half of 2011, partially offset by lower realized prices from the merchant wind projects.


Energy Trading

AOI from energy trading activities decreased $16 million and $38 million for the third quarter and nine months ended September 30, 2011, respectively, compared to the corresponding periods of 2010. The third quarter and year-to-date decreases were partially due to reduced revenues from power trading activities and partially due to the allocation to Homer City the benefit of an arrangement that allows EMMT to deliver power into the NYISO from Homer City.

Table of Contents


Adjusted Operating Income from Other Projects

Big 4 Projects.    AOI from the Big 4 projects decreased in 2011, compared to the corresponding periods of 2010, primarily due to lower capacity prices under Midway-Sunset's new power purchase agreement and lower capacity and energy sales margin.

Doga.    EME received distributions of $26 million from the Doga project in the second quarter of 2011 and $15 million in the first quarter of 2010. The increase in distributions is primarily due to elimination of restricted cash as a result of the repayment of the remaining project debt. AOI is recognized when cash is distributed from the project as the Doga project is accounted for on the cost method.

March Point.    During the first quarter of 2010, AOI from the March Point project was $17 million due to an equity distribution received from the project. EME subsequently sold its ownership interest in the March Point project to its partner in February 2010.

Seasonality.    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.

Homer City Outage

During the first half of 2011, Homer City Units 1 and 2 were off line due to a steam pipe rupture at Unit 1 and precautionary maintenance at Unit 2. While Unit 1 returned to service on April 5, 2011 and Unit 2 on May 25, 2011, the outages and the continuation of low power prices impacted Homer City's liquidity. As a result, in order to have sufficient working capital available for operating expenses and to pay the equity portion of Homer City's rent payment that was due April 1, 2011 to the owner-lessors, Homer City had to defer certain fuel deliveries, arrange for accelerated payments by EMMT for future energy deliveries under an intercompany arrangement in place between EMMT and Homer City, and draw $12 million from the $20 million equity rent reserve established under its sale-leaseback transaction documents. At September 30, 2011, the equity rent reserve balance was restored back to $20 million, and Homer City had delivered energy sufficient to eliminate the accelerated payments by EMMT. Homer City must continue to make equity rent payments in order to be entitled to make future distributions. Effective April 1, 2011, EMMT allocated to Homer City the benefit of an arrangement that allows EMMT to deliver power into the NYISO from Homer City. Accordingly, since April 1, 2011, these revenues have been recorded as part of Homer City's revenues in lieu of their prior classification as EMMT trading revenues. EMMT realized trading revenues of $28 million under this arrangement in 2010.

The actions described above also resulted in Homer City being in compliance with the covenant requirements of its sale-leaseback documents relating to the payment of equity rent at April 1, 2011.

Environmental Expenditures

Midwest Generation plants' environmental expenditures include $13 million for remaining expenditures in 2011 related to selective non-catalytic reduction (SNCR) equipment and $501 million for expenditures for the remainder of 2011 to 2013 to begin to retrofit initial units using dry scrubbing with sodium-based sorbents to comply with CPS requirements for SO2 emissions, assuming all units are retrofitted for an estimated aggregate cost of $1.2 billion. EME believes that Midwest Generation's current environmental remediation plan developed to comply with the CPS, along with the allowances allocated to it under CSAPR, will be sufficient to comply with the requirements of CSAPR and the US EPA's proposed regulation on HAP emissions. In order to achieve compliance, Midwest Generation has begun work to install SO2 controls at certain of its plants. Midwest Generation could elect to shut down units instead of installing controls to be in compliance with the CPS and other requirements, and, therefore, decisions about any particular combination of retrofits and shutdowns it may ultimately employ to comply remain subject to conditions applicable at the time decisions are required or made. Accordingly, the environmental expenditures for Midwest Generation in the preceding table represent current projects only and are subject to change based upon a number of considerations. Actual expenditures could be higher or lower. Preconstruction engineering and initial construction work for a project may occur in 2011 in advance of a final decision to continue or complete the project. For additional discussion, see "Management's Overview—Midwest Generation Compliance Plans and Costs."

The capital investment plan set forth in the previous table does not include environmental capital expenditures that Homer City will be required to undertake to meet the requirements of CSAPR. The timing, selection of technology and ultimate capital costs remain uncertain. For a discussion of environmental regulations, see "Management's Overview—Cross-State Air Pollution Rule," "Management's Overview—Homer City Capital Needs and Liquidity," and refer to "Environmental Matters and Regulations" in Item 1 on page 19 of EME's annual report on Form 10-K for the year ended December 31, 2010.


Plant Capital Expenditures

Plant capital expenditures in the preceding table relate to non-environmental projects such as upgrades to boiler and turbine controls, replacement of major boiler components, generator stator rewinds, and development of a coal-cleaning plant refuse site and a new ash disposal site.


Walnut Creek Project Expenditiures

In July 2011, EME secured $495 million in construction and term financing for the Walnut Creek project. For additional information, see "Edison Mission Energy and Subsidiaries Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements—Project Financings—Walnut Creek."


Renewable Energy Projects

In the third quarter of 2011, EME acquired the 80 MW Broken Bow I and the 40 MW Crofton Bluffs wind projects. Commercial operations of the Broken Bow I and the Crofton Bluffs projects are expected in the fourth quarter of 2012. The Taloga wind project achieved commercial operation on July 13, 2011.

At September 30, 2011, EME had a development pipeline of potential wind projects with projected installed capacity of approximately 3,800 MW. The development pipeline represents potential wind

projects with respect to which EME either owns the project rights or has exclusive acquisition rights. The pace of additional growth in EME's renewable program will be subject to the availability of third-party equity capital. At September 30, 2011, EME had capitalized costs and turbine deposits totaling $26 million related to renewable energy development efforts. To the extent that the renewable energy projects are not successful, EME would record a charge to write down the carrying amount of these assets.

Consolidated Cash Flows from Operating Activities

The decrease in the first nine months of 2011 as compared to the first nine months of 2010 in cash provided by operating activities from continuing operations was primarily attributable to tax-allocation payments received of $182 million in 2011 compared to $100 million in 2010 and $310 million of U.S. Treasury grants received in 2011, compared to $92 million in 2010. These increases were offset by lower pre-tax income.


Consolidated Cash Flows from Financing Activities

The decrease in the first nine months of 2011 as compared to the first nine months of 2010 in cash provided by financing activities from continuing operations was primarily attributable to higher borrowings at wind projects in 2010 than in 2011, partially offset by borrowings at the Walnut Creek gas project in 2011.


Consolidated Cash Flows from Investing Activities

Cash used in investing activities for the first nine months of 2011 and 2010 primarily consisted of capital expenditures for construction of energy projects and other plant improvements.

Credit Ratings

Overview

Credit ratings for EME, Midwest Generation and EMMT as of September 30, 2011 were as follows:

 
  Moody's Rating
  S&P Rating
  Fitch Rating
 

EME1

  Caa1   B-   CCC

Midwest Generation2

  Ba3     B+   BB-

EMMT

  Not Rated   B-   Not Rated
 
1
Senior unsecured rating.

2
First priority senior secured rating.

All the above ratings are on negative outlook. EME cannot provide assurance that its current credit ratings or the credit ratings of its subsidiaries will remain in effect for any given period of time or that one or more of these ratings will not be lowered. EME notes that these credit ratings are not recommendations to buy, sell or hold its securities and may be revised at any time by a rating agency.

EME does not have any "rating triggers" contained in subsidiary financings that would result in a requirement to make equity contributions or provide additional financial support to its subsidiaries, including EMMT. However, coal contracts at Midwest Generation include provisions that provide the right to request additional collateral to support payment obligations for delivered coal and may vary based on Midwest Generation's credit ratings. Furthermore, EMMT also has hedge contracts that do not require margin, but contain the right of each party to request additional credit support in the form of adequate assurance of performance in the case of an adverse development affecting the other party. As of September 30, 2011, there were no open positions under hedge contracts that would require EMMT to provide adequate assurance in the form of additional credit support.


Credit Rating of EMMT

For a discussion of the effect of EMMT's credit rating on EME's ability to sell forward the output of the Homer City plant through EMMT, refer to "Credit Rating of EMMT" in Item 7 on page 60 of EME's annual report on Form 10-K for the year ended December 31, 2010.


Margin, Collateral Deposits and Other Credit Support for Energy Contracts

To reduce its exposure to market risk, EME hedges a portion of its 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 EMMT's hedging and trading activities. However, EME has historically also provided collateral in the form of cash and letters of credit for the benefit of counterparties related to the net of accounts payable, accounts receivable, unrealized losses, and unrealized gains in connection with these hedging and trading activities. For further details, see "Edison Mission Energy and Subsidiaries Notes to Consolidated Financial Statements—Note 6. Derivative Instruments and Hedging Activities."

Future cash collateral requirements may be higher than the margin and collateral requirements at September 30, 2011 if wholesale energy prices change or if EMMT enters into additional transactions. EME estimates that margin and collateral requirements for energy and congestion contracts

outstanding at September 30, 2011 could increase by approximately $82 million over the remaining life of the contracts using a 95% confidence level.


EME's Liquidity as a Holding Company

EME's Credit Facility Financial Ratios

EME's credit facility contains financial covenants which require EME to maintain a minimum interest coverage ratio and a maximum corporate-debt-to-capital ratio as such terms are defined in the credit facility. The following details of EME's interest coverage ratio and a maximum corporate-debt-to-capital ratio are provided as an aid to understanding the components of the computations as defined in the credit facility. This information is not intended to measure the financial performance of EME and, accordingly, should not be used in lieu of the financial information set forth in EME's consolidated financial statements. At September 30, 2011, EME and its subsidiaries were in compliance with the terms of their debt covenants.

EME's Senior Notes and Guaranty of Powerton-Joliet Leases

EME is restricted under applicable agreements from selling or disposing of assets, which includes distributions, if the aggregate net book value of all such sales and dispositions during the most recent 12-month period would exceed 10% of consolidated net tangible assets as defined in such agreements computed as of the end of the most recent fiscal quarter preceding the sale or disposition in question. At September 30, 2011, the maximum permissible sale or disposition of EME assets is calculated as follows:

(in millions)
   
 
   

Consolidated Net Tangible Assets

       
 

Total consolidated assets

  $ 9,600  
 

Less:

       
   

Consolidated current liabilities

    491  
   

Intangible assets

    132  
       

  $ 8,977  
   

10% Threshold

  $ 898  
   

This limitation does not apply if the proceeds are invested in assets in similar or related lines of business of EME. Furthermore, EME may sell or otherwise dispose of assets in excess of such 10% limitation if the proceeds from such sales or dispositions, which are not reinvested as provided above, are retained as cash or cash equivalents or are used to repay debt.

As a wholly owned indirect subsidiary of Edison International, EME is subject to determinations made by its directors, each of whom is appointed by Edison International, to act in the interests of Edison International and its shareholders, which may result in EME making distributions of cash or assets, subject to the limitations described above and applicable law, at any time or from time to time, which may affect EME's assets held or under development.
