NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 1. Summary of Significant Accounting Policies

Edison International's principal wholly owned subsidiaries are SCE, a rate-regulated electric utility that supplies electric energy to a 50,000 square-mile area of central, coastal and southern California; and EMG, a wholly owned competitive power generation subsidiary. EMG is a holding company whose subsidiaries and affiliates are engaged in the business of developing, acquiring, owning or leasing, operating and selling energy and capacity from independent power production facilities. EMG's subsidiaries also conduct hedging and energy trading activities in competitive power markets.


Basis of Presentation

Edison International's significant accounting policies were described in Note 1 of "Edison International Notes to Consolidated Financial Statements" included in the 2009 Form 10-K. Edison International follows the same accounting policies for interim reporting purposes, with the exception of accounting principles adopted as of January 1, 2010 as discussed below in "—New Accounting Guidance." This quarterly report should be read in conjunction with such financial statements.

In the opinion of management, all adjustments, including recurring accruals, have been made that are necessary to fairly state the consolidated financial position, results of operations and cash flows in accordance with accounting principles generally accepted in the United States of America for the periods covered by this quarterly report on Form 10-Q. The results of operations for the three- and six-month periods ended June 30, 2010 are not necessarily indicative of the operating results for the full year.

Management has performed an evaluation of subsequent events through the date the financial statements were issued.

The December 31, 2009 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Except as indicated, amounts presented in the Notes to the Consolidated Financial Statements relate to continuing operations.


Cash and Equivalents

Cash equivalents included money market funds totaling $600 million and $1,457 million at June 30, 2010 and December 31, 2009, respectively. The carrying value of cash equivalents equals the fair value, as all investments have maturities of three months or less. For further discussion of money market funds, see Note 10.

Edison International temporarily invests the ending daily cash balance in its primary disbursement accounts until required for check clearing. Edison International reclassified $201 million and $224 million of checks issued against these accounts, but not yet paid by the financial institution, from cash to accounts payable at June 30, 2010 and December 31, 2009, respectively.


Earnings Per Share

Edison International computes EPS using the two-class method, which is an earnings allocation formula that determines EPS for each class of common stock and participating security. Edison International's

participating securities are stock-based compensation awards payable in common shares, including stock options, performance shares and restricted stock units, which earn dividend equivalents on an equal basis with common shares. Stock options awarded during the period 2003 through 2006 received dividend equivalents. Stock options awarded prior to 2002 and after 2006 were granted without a dividend equivalent feature. EPS attributable to Edison International common shareholders was computed as follows:

New Accounting Guidance

Accounting Guidance Adopted in 2010

Consolidation – Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities

The FASB issued an accounting standards update that changes how a company determines when an entity, that is insufficiently capitalized or is not controlled through voting (or similar rights), should be consolidated. The determination of whether a company is required to consolidate an entity is based on, among other things, an ability to direct the activities of the entity that most significantly impact the entity's economic performance and whether the entity has an obligation to absorb losses or the right to receive expected returns of the entity. This guidance requires a company to provide additional disclosures about its involvement with variable interest entities and any significant changes in risk exposure due to that involvement. Edison International adopted this guidance prospectively effective January 1, 2010. The impact of adopting this guidance resulted in the deconsolidation of assets totaling $683 million and the consolidation of assets totaling $99 million at January 1, 2010, and resulted in a cumulative effect adjustment which increased retained earnings by $15 million. For further discussion, see Note 13.

Fair Value Measurements and Disclosures

The FASB issued an accounting standards update that provides for new disclosure requirements related to fair value measurements. The requirements, which Edison International adopted effective January 1, 2010, include separate disclosure of significant transfers in and out of Levels 1 and 2 and the reasons for the transfers. The update also clarified existing disclosure requirements for the level of disaggregation, inputs and valuation techniques. In addition, effective January 1, 2011, the Level 3 reconciliation of fair value measurements using significant unobservable inputs should include gross rather than net information about purchases, sales, issuances and settlements. The guidance impacts disclosures only. For further discussion, see Note 10.


Accounting Guidance Not Yet Adopted

In October 2009, the FASB issued amended guidance for identifying separate deliverables in a revenue-generating transaction where multiple deliverables exist, and provides guidance for allocating and recognizing revenue 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 effective beginning January 1, 2011 and is required to be applied prospectively to new or significantly modified revenue arrangements. Edison International is currently assessing the effects this guidance may have on its consolidated financial statements.


Note 2. Derivative Instruments and Hedging Activities

Electric Utility

Commodity Price Risk

SCE is exposed to commodity price risk, which represents the potential impact that can be caused by a change in the market value of a particular commodity. SCE's hedging program reduces ratepayer exposure to variability in market prices related to SCE's power and gas activities. As part of this program, SCE enters into energy options, swaps, forward arrangements, tolling arrangements and congestion revenue rights ("CRRs"). These transactions are pre-approved by the CPUC or executed in compliance with CPUC-approved procurement plans. SCE recovers its related hedging costs through the ERRA balancing account and as a result, exposure to commodity price risk is not expected to impact earnings, but may impact cash flows.

SCE's electricity price exposure arises from energy produced and sold in the MRTU market as a result of differences between SCE's load requirements versus the amount of energy delivered from its generating facilities, existing bilateral contracts and CDWR contracts allocated to SCE.

A portion of SCE's purchased power supply is subject to natural gas price volatility. SCE's natural gas price exposure arises from purchasing natural gas for generation at Mountainview and peaker plants, from bilateral contracts where pricing is based on natural gas prices (this includes contract energy prices for most renewable QFs which are based on the monthly index price of natural gas delivered at the southern California border), and power contracts in which SCE has agreed to provide the natural gas needed for generation, referred to as tolling arrangements.

In compliance with a CPUC mandate, SCE held an open, competitive solicitation that produced agreements with different project developers who have agreed to construct new southern California generating resources. SCE has entered into a number of contracts which are recorded as derivative instruments. The contracts provide for fixed capacity payments as well as pricing for energy delivered based on a heat rate and contractual operation and maintenance prices. However, due to uncertainty regarding the availability of required emission credits, some of the new generating resources may not be constructed and the contracts associated with these resources could therefore terminate, at which time SCE would no longer account for these contracts as derivatives.

Income Statement Impact of Derivative Instruments

SCE recognizes realized gains and losses on derivative instruments as purchased-power expense and recovers these costs, subject to reasonableness, from ratepayers. As a result, realized gains and losses are not reflected in earnings, but may temporarily affect cash flows. Due to expected future recovery from ratepayers, unrealized gains and losses are recorded as regulatory assets or liabilities and therefore are not reflected in earnings. The results of derivative activities and related regulatory offsets are recorded in cash flows from operating activities in the consolidated statements of cash flows.

Contingent Features/Credit-Related Exposure

Certain derivative instruments and power procurement contracts under SCE's power and natural gas hedging activities contain collateral requirements. SCE has historically provided collateral in the form of cash and/or letters of credit for the benefit of counterparties. These requirements can vary depending upon the level of unsecured credit extended by counterparties, changes in market prices relative to contractual commitments, and other factors.

Certain of these power contracts contain a provision that requires SCE to maintain an investment grade credit rating from each of the major credit rating agencies, referred to as a "credit-risk-related contingent feature." If SCE's credit rating were to fall below investment grade, SCE may be required to pay the derivative liability or post additional collateral. The aggregate fair value of all derivative liabilities with these credit-risk-related contingent features was $232 million and $91 million, as of June 30, 2010 and December 31, 2009, respectively, for which SCE has posted no collateral to its counterparties. If the credit-risk-related contingent features underlying these agreements were triggered on June 30, 2010, SCE would be required to post $20 million of additional collateral.


Competitive Power Generation

EMG uses derivative instruments to reduce exposure to market risks that arise from fluctuations in prices of electricity, capacity, fuel, emission allowances, and transmission rights. Additionally, EMG's financial results can be affected by fluctuations in interest rates. To the extent that EMG 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 EMG's consolidated balance sheets with offsetting changes recorded in the consolidated statements of income (loss). For transactions that qualify for accounting hedge treatment, the fair value is recognized, to the extent effective, on EMG's consolidated balance sheets with offsetting changes in fair value recognized in accumulated other comprehensive income until the related forecasted transaction occurs.

EMG's hedge products include forward and futures contracts that qualify for hedge accounting. This category excludes power contracts for the fossil-fueled facilities which meet the normal sales and purchase exception and are accounted for on the accrual method.

2
EMG's hedge transactions for capacity result from bilateral trades. Capacity sold in the PJM RPM auction is not accounted for as a derivative.

3
EMG 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.

Contingent Features/Credit Related Exposure

Certain derivative instruments contain margin and collateral deposit requirements. Since EME's credit ratings are below investment grade, EME has 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 derivative activities. Certain derivative contracts do not require margin, but contain provisions that require EME or Midwest Generation to

16


Table of Contents


comply with the terms and conditions of their respective credit facilities. The credit facilities each contain financial covenants. Some hedge contracts include provisions related to a change in control or material adverse effect resulting from amendments or modifications to the related credit facility. Failure by EME or Midwest Generation to comply with these provisions may result in a termination event under the hedge contracts, enabling the counterparties to terminate and liquidate all outstanding transactions and demand immediate payment of amounts owed to them. EMMT has hedge contracts that do not require margin, but provide that each party can request additional credit support in the form of adequate assurance of performance in the case of an adverse development affecting the other party. The aggregate fair value of all derivative instruments with credit-risk-related contingent features is in an asset position at June 30, 2010 and, accordingly, the contingent features described above do not currently have a liquidity exposure. Future increases in power prices could expose EME, Midwest Generation or EMMT to termination payments or additional collateral postings under the contingent features described above.


Note 3. Liabilities and Lines of Credit

Long-Term Debt

In March 2010, SCE issued $500 million of 5.5% first and refunding mortgage bonds due in 2040. In May 2010, SCE reissued $144 million of 5.0% tax-exempt pollution control bonds due in 2035. The proceeds from these bonds were used to repay commercial paper borrowings and for general corporate purposes.

EMG consolidated the Ambit project on January 1, 2010. At June 30, 2010, this project had $71 million of bonds payable, which are supported by a letter of credit. Principal payments are due annually through October 1, 2017. Interest rates are reset weekly based on current bond yields for similar securities. The average interest rate for the six months ended June 30, 2010 was 0.26%. Annual maturities of this debt at June 30, 2010 for the next five years are summarized as follows: $8 million in 2010, $8 million in 2011, $9 million in 2012, $10 million in 2013, and $10 million in 2014. In January 2010, Edison Capital repaid in full its medium-term loans. The balance of these loans was $89 million at December 31, 2009.


Credit Agreements and Short-Term Debt

In March 2010, SCE replaced its $500 million 364-day revolving credit facility with a new $500 million three-year credit facility that terminates in March 2013.

SCE's short-term debt is generally used to finance fuel inventories, balancing account under-collections and general, temporary cash requirements including power purchase payments. At June 30, 2010, the outstanding short-term debt was $215 million at a weighted-average interest rate of 0.42%. This short-term debt is supported by $2.9 billion of credit lines. At December 31, 2009, the outstanding short-term debt was zero.

In March 2010, EMG completed through its subsidiary, Cedro Hill Wind, LLC, a non-recourse financing of its interests in the Cedro Hill wind project. The financing included a $135 million construction loan that is required to be converted to a 15-year amortizing term loan by May 31, 2011, subject to meeting specified conditions. As of June 30, 2010, there was $65 million outstanding under the construction loan at a weighted average interest rate of 3.35%.

Table of Contents

Edison International (parent) short-term debt is generally used to finance operating expenses and dividends. At June 30, 2010, the outstanding short-term debt was $215 million at a weighted-average interest rate of 0.71%. At December 31, 2009, the outstanding short-term debt was $85 million at a weighted-average interest rate of 0.60%.


Letters of Credit

As of June 30, 2010, letters of credit issued under EME and its subsidiaries' credit facilities aggregated $129 million and are scheduled to expire as follows: $36 million in 2010 and $93 million in 2011. Letters of credit issued under SCE's credit facilities aggregated $11 million and are scheduled to expire in 2010.

The CPUC requires flow-through rate-making treatment for the current tax benefit arising from certain property-related and other temporary differences which reverse over time. The accounting treatment for these temporary differences results in recording regulatory assets and liabilities for amounts that would otherwise be recorded to deferred income tax expense.


Global Settlement

During the second quarter of 2010, Edison International recognized a $138 million earnings benefit resulting from acceptance by the California Franchise Tax Board of the tax positions finalized with the IRS in 2009 as part of the Global Settlement for tax years 1986 through 2002 (described in "Item 8. Edison International Notes to Consolidated Financial Statements—Note 4. Income Taxes" of the 2009 Form 10-K) and revision to interest recorded on the federal Global Settlement. Edison International is awaiting receipt of final interest calculations from the California Franchise Tax Board.

During the six months ended June 30, 2009, Edison International recorded a consolidated after-tax earnings charge of $274 million related to the Global Settlement finalized with the IRS and termination of Edison Capital's cross-border leases ($920 million pre-tax loss).


Change in Tax Accounting Method for Asset Removal Costs

During the second quarter of 2010, the IRS approved Edison International's request to change its tax accounting method for asset removal costs primarily related to SCE's infrastructure replacement program. As a result, Edison International recognized a $40 million earnings benefit ($28 million of which relates to asset removal costs incurred prior to 2010) from deducting asset removal costs earlier in the construction cycle. These deductions are recorded on a flow-through basis.


Health Care Legislation

During the first quarter of 2010, Edison International recognized a $39 million non-cash charge to reverse previously recognized federal tax benefits eliminated by the federal health care legislation enacted in March 2010. The Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act, includes a provision that eliminates the federal tax deduction of retiree health care costs to the extent those costs are eligible for federal Medicare Part D subsidies. Although this change does not take effect until January 1, 2013, Edison International is required to recognize the full accounting impact of the legislation in its financial statements in the period of enactment.

Stock-Based Compensation

During the first quarter of 2010, Edison International granted its 2010 stock-based compensation awards, which included stock options, performance shares and restricted stock units. Total stock-based compensation expense (reflected in the caption "Other operation and maintenance" on the consolidated statements of income (loss)) was $9 million and $10 million for the three months ended June 30, 2010 and 2009, respectively, and was $17 million and $16 million for the six months ended June 30, 2010 and 2009, respectively. The income tax benefit recognized in the consolidated statements of income (loss) was $4 million for the three months ended June 30, 2010 and 2009, and was $7 million and $6 million for the six months ended June 30, 2010 and 2009, respectively. Consistent with SCE's 2009 GRC, no stock-based compensation has been capitalized since December 31, 2008. Excess tax benefits included in "Settlements of stock-based compensation – net" in the financing section of the consolidated statements of cash flows were $2 million and $4 million for the six months ended June 30, 2010 and 2009, respectively.

Note 6. Commitments and Contingencies

Commitments

SCE entered into a 20-year power purchase contract which is classified as a capital lease and is expected to be recorded on the consolidated balance sheets upon commencement of the contract in 2013. SCE's commitments upon commencement are estimated to be: $23 million in 2013, $44 million in 2014, and $805 million for the remaining period thereafter.

22


Table of Contents


Other Commitments

At June 30, 2010, SCE had power purchase contracts with additional commitments estimated to be: $67 million for the remainder of 2010, $83 million in 2011, $67 million in 2012, $39 million in 2013, $39 million in 2014, and $613 million for the remaining period thereafter.

At June 30, 2010, EMG's subsidiaries had firm commitments to spend approximately $447 million during the remainder of 2010 on capital and construction expenditures. These expenditures primarily relate to the construction of wind projects. EMG intends to fund these expenditures through project-level and turbine vendor financing, U.S. Treasury grants, cash on hand and cash generated from operations.

EMG has entered into various turbine supply agreements with vendors to support its wind development efforts. As of June 30, 2010, EME had commitments, excluding turbines subject to the legal dispute described below, to purchase 46 wind turbines (69 MW) and had 13 wind turbines (33 MW) in storage to be used for future wind projects. EMG has 59 wind turbines (102 MW) available for future projects, excluding turbines allocated to projects in construction and turbines subject to the legal dispute. EMG has payment commitments related to wind turbines of $85 million due in 2011. During the second quarter, EMG deferred the delivery and $82 million in payments for 69 MW of turbines to January 2011.

Excluded from the turbine agreements referred to above is a turbine supply agreement between Mitsubishi Power Systems Americas, Inc. and EME, which is subject to a legal dispute. EME has made deposits of $68 million for the purchase of 83 wind turbines (199 MW) under this agreement. The remaining payments under this agreement subject to dispute are $289 million, mostly related to undelivered wind turbines. Resolution of this dispute will impact whether, and to what extent, future payments may be due under this agreement.

At June 30, 2010, Midwest Generation and Homer City had fuel purchase commitments with various third-party suppliers for the purchase of coal. Based on the contract provisions, which consist of fixed prices, subject to adjustment clauses, these minimum commitments are estimated to aggregate $936 million, summarized as follows: $251 million for the remainder of 2010, $405 million in 2011, $247 million in 2012, and $33 million in 2013.

At June 30, 2010, Midwest Generation and Homer City each had contractual agreements for the transport of coal to their respective facilities. The commitments under these contracts are based on either actual coal purchases or minimum quantities. Accordingly, contractual obligations for transportation based on actual coal purchases are derived from committed coal volumes set forth in fuel supply contracts. The minimum commitments under these contracts are estimated to aggregate $314 million, summarized as follows: $143 million for the remainder of 2010, and $171 million in 2011.

In addition to the above, in July 2010, Midwest Generation entered into additional contracts for the purchase of coal. These commitments, together with the estimated transportation costs under the existing agreements, are estimated to be $101 million for 2011.

SCE and EME have letters of credit outstanding under their credit facilities. For further discussion, see Note 3.

Guarantees and Indemnities

Edison International's subsidiaries have various financial and performance guarantees and indemnifications which are issued in the normal course of business. As discussed below, these contracts include performance guarantees, guarantees of debt and indemnifications.


Environmental Indemnities Related to the Midwest Generation Plants

In connection with the acquisition of the Midwest Generation plants, EME agreed to indemnify Commonwealth Edison with respect to specified environmental liabilities before and after December 15, 1999, the date of sale. The indemnification claims are reduced by any insurance proceeds and tax benefits related to such claims and are subject to a requirement that Commonwealth Edison takes all reasonable steps to mitigate losses related to any such indemnification claim. This indemnification for environmental liabilities is not limited in term and would be triggered by a valid claim from Commonwealth Edison. 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. 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 Lawsuit." The sale-leaseback participants have requested similar indemnification. 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 its 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. As a general matter, Commonwealth Edison and Midwest Generation apportion responsibility for future asbestos-related claims based upon the number of exposure sites that are Commonwealth Edison locations or Midwest Generation locations. 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 2011. There were approximately 217 cases for which Midwest Generation was potentially liable and that had not been settled and dismissed at June 30, 2010. Midwest Generation had recorded a $49 million liability at June 30, 2010 for previous, pending and future claims.

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 Facilities

In connection with the acquisition of the Homer City facilities, Homer City agreed to indemnify the sellers with respect to specified environmental liabilities before and after the date of sale. Payments would be triggered under this indemnity by a valid claim from the sellers. EME guaranteed this

24


Table of Contents


obligation of Homer City. Also, in connection with the sale-leaseback transaction related to the Homer City facilities, Homer City agreed to indemnify the lessors for specified environmental liabilities. Due to the nature of the obligation under this indemnity provision, it is not subject to a maximum potential liability and does not have an expiration date. For discussion of the NOV received by Homer City and associated indemnity claims, see "—Contingencies—Homer City New Source Review Notice of Violation." EME has not recorded a liability related to this indemnity.


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. Payments would be triggered under these indemnities by valid claims from the sellers or purchasers, as the case may be. At June 30, 2010, EME had recorded a liability of $39 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 asset 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). Due to the nature of the obligations under these indemnity agreements, a maximum potential liability cannot be determined. Not all indemnities under the asset sale agreements have specific expiration dates. Payments would be triggered under these indemnities by valid claims from the sellers or purchasers, as the case may be. No significant amounts are recorded as a liability for these matters.

In connection with the sale-leaseback transactions related to the Homer City facilities 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. Although the Collins Station lease terminated in April 2004, Midwest Generation's tax indemnity agreement with the former lease equity investor is still in effect. Under these tax indemnity agreements, these entities agreed to indemnify the lessors in the sale-leaseback transactions for specified adverse tax consequences that could result in certain situations set forth in each tax indemnity agreement, including specified defaults under the respective leases. 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. No significant amounts are recorded as a liability for these matters.


Indemnity Provided as Part of the Acquisition of Mountainview

In connection with the acquisition of Mountainview, SCE agreed to indemnify the seller with respect to specific environmental claims related to SCE's previously owned San Bernardino Generating Station, divested by SCE in 1998 and reacquired as part of the Mountainview acquisition. SCE retained certain responsibilities with respect to environmental claims as part of the original divestiture of the station. The aggregate liability for either party to the purchase agreement for damages and other amounts is a maximum of $60 million. This indemnification for environmental liabilities expires on or before March 12, 2033. SCE has not recorded a liability related to this indemnity.

25


Table of Contents


Mountainview Filter Cake Indemnity

The Mountainview power plant utilizes water from on-site groundwater wells and City of Redlands ("City") recycled water for cooling purposes. Unrelated to the operation of the plant, this water contains perchlorate. The pumping of the water removes perchlorate from the aquifer beneath the plant and concentrates it in the plant's wastewater treatment "filter cake." Use of this impacted groundwater for cooling purposes was mandated by Mountainview's California Energy Commission permit. SCE has indemnified the City for cleanup or associated actions related to groundwater contaminated by perchlorate due to the disposal of filter cake at the City's solid waste landfill. The obligations under this agreement are not limited to a specific time period or subject to a maximum liability. SCE has not recorded a liability related to this indemnity.


Other Edison International Indemnities

SCE provides other indemnifications through contracts entered into in the normal course of business. These are primarily indemnifications against adverse litigation outcomes in connection with underwriting agreements, and specified environmental indemnities and income taxes with respect to assets sold. SCE's obligations under these agreements may be limited in terms of time and/or amount, and in some instances SCE may have recourse against third parties for certain indemnities. The obligated amounts of these indemnifications often are not explicitly stated, and the overall maximum amount of the obligation under these indemnifications cannot be reasonably estimated. SCE has not recorded a liability related to these indemnities.


Contingencies

In addition to the matters disclosed in these Notes, Edison International is involved in other legal, tax and regulatory proceedings before various courts and governmental agencies regarding matters arising in the ordinary course of business. Edison International believes that the outcome of these other proceedings will not materially affect its results of operations, financial position or liquidity.


Environmental Developments

Edison International is subject to numerous environmental laws and regulations, which typically require a lengthy and complex process for obtaining licenses, permits and approvals and require it to incur substantial costs to operate existing facilities, construct and operate new facilities, and mitigate or remove the effect of past operations on the environment.

Possible developments, such as the enactment of more stringent environmental laws and regulations, proceedings that may be initiated by environmental and other regulatory authorities, cases in which new theories of liability are recognized, and settlements agreed to by other companies that establish precedent or expectations for the power industry, could affect the costs and the manner in which business is conducted, and could cause substantial additional capital expenditures or operational expenditures or the ceasing of operations at certain facilities. There is no assurance that any additional costs arising from such developments would be recovered from customers or that Edison International's financial position, results of operations and cash flows would not be materially affected by these developments.

Midwest Generation Environmental Compliance Plans and Costs

During the second quarter of 2010, Midwest Generation continued its permitting and planning activities for NO x and SO 2 controls to meet the requirements of the CPS. Midwest Generation has now received all necessary permits from the Illinois EPA allowing the installation of SNCR technology on multiple units to meet the NO x portion of the CPS.

In addition, work continued on the possible employment of FGD technology using dry scrubbing with sodium-based sorbents as a method to comply with the SO 2 portion of the CPS. Testing of this technology demonstrated significant reductions in SO 2 emissions when using the low-sulfur coal employed by Midwest Generation. Use of this technology in combination with low-sulfur coal is expected to require substantially less capital and installation time than the spray dryer absorber technology originally contemplated, but would likely result in higher ongoing operating costs and may consequently result in lower dispatch rates and competitiveness of Midwest Generation's plants. Also, the use of dry scrubbing with sodium-based sorbents to meet environmental regulations will likely require Midwest Generation to incur the costs of upgrading its particulate removal systems.

Based on this work, Midwest Generation estimates the cost of retrofitting all units, using dry scrubbing with sodium-based sorbents to comply with CPS requirements for SO 2 emissions, at approximately $1.2 billion in 2010 dollars. If completed, these expenditures would be incurred over multiple years. Midwest Generation expects to seek permits from the Illinois EPA for select initial units later this year.

Decisions regarding whether or not to proceed with the above projects or other approaches to compliance 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 shut down units, instead of installing controls, to be in compliance with the CPS, and, therefore, decisions about any particular combination of retrofits and shutdowns it may ultimately employ to comply with the CPS also remain subject to conditions applicable at the time decisions are required or made. Due to existing uncertainties about these factors, Midwest Generation may defer final decisions about particular units for the maximum time available. Accordingly, final decisions on whether to install controls, to install particular kinds of controls, and to actually expend capital that is budgeted may not occur until 2012 for some of the units and potentially later for others.


Homer City Environmental Issues and Capital Resource Limitations

Homer City operates SCR equipment on all three units to reduce NO x emissions, operates FGD equipment on Unit 3 to reduce SO 2 emissions, and uses coal-cleaning equipment on site to reduce the ash and sulfur content of raw coal to meet both combustion and environmental requirements. Homer City may be required to install additional environmental equipment on Unit 1 and Unit 2 to comply with environmental regulations for future operations. For further information, see "—Transport Rule" and "—Homer City New Source Review Notice of Violation." Restrictions under the agreements entered into as part of Homer City's 2001 sale-leaseback transaction could affect, and in some cases significantly limit or prohibit, Homer City's ability to incur indebtedness or make capital expenditures. Homer City will have limited ability to obtain additional outside capital for such projects without amending its lease and related agreements. EME is under no contractual obligation to provide funding to Homer City.

Greenhouse Gas Regulation

On June 3, 2010, the US EPA finalized the PSD and Title V GHG tailoring rule. The effective date of the final rule is August 2, 2010. The emissions thresholds for CO2 equivalents in the final rule are as follows:

January – June 2011 75,000 tons per year for new and modified sources already subject to PSD for pollutants other than GHGs

July 2011 – June 2013


100,000 tons per year for new sources, and
75,000 tons per year for modified sources

Petitions for judicial review of the GHG tailoring rule are to be submitted by August 2, 2010. Legal challenges to the GHG tailoring rule have been filed.


Transport Rule

On July 6, 2010, the US EPA issued a Notice of Proposed Rulemaking for a proposed rule, known as the Transport Rule, which would require 31 eastern states (including Pennsylvania and Illinois) and the District of Columbia to substantially reduce power plant emissions of NO x and SO 2 starting in 2012, with additional reductions in 2014. The Transport Rule would replace the Clean Air Interstate Rule, which had been remanded to the US EPA in 2008 for issuance of a revised rule.

The US EPA has proposed three possible approaches to emissions allowance trading. Under its preferred approach, a pollution limit would be set for each state, intrastate trading would be permitted among power plants, and limited interstate trading would also be permitted consistent with the requirement that each state meet its own pollution control obligations. Under the first alternative, a pollution limit would be set for each state, and only intrastate trading of allowances would be permitted. Under the second alternative, a pollution limit would be set for each state and an emissions limit would be set for each power plant, and limited emissions averaging would be permitted among affected units.

Under the Transport Rule, each covered state would initially be subject to a federal implementation plan designed to reduce pollution that significantly contributed to nonattainment of, or interferes with the maintenance of, NAAQS in other states. States would be able to choose to develop state implementation plans to replace the federal implementation plans.

Comments on the Transport Rule will be due 60 days after its publication in the Federal Register. The Transport Rule is scheduled to be finalized in 2011. The Clean Air Interstate Rule will remain in place until that time. EME believes that the US EPA's preferred approach to emissions allowance trading would provide allowance allocations which are adequate for the Midwest Generation plants based on projected emissions using the Illinois CPS allowable emission rates. The proposed rule, if adopted, may require the installation of additional environmental equipment to reduce SO 2 emissions at Units 1 and 2 of the Homer City facilities to continue to operate under the rule.


National Ambient Air Quality Standard for Sulfur Dioxide

On June 2, 2010, the US EPA finalized the primary NAAQS for SO 2 by establishing a new one-hour standard at a level of 75 parts per billion. The final standard is in line with EME's expectations and is

28


Table of Contents


being taken into account in EME's environmental compliance strategy. Revisions to state implementation plans to achieve compliance with the new standard are due to be submitted to the US EPA by February 2014. The US EPA anticipates that the deadline for attainment with the SO 2 NAAQS will be August 2017 (five years after the US EPA intends to finalize initial determinations as to the areas of the country that are and are not in attainment with the primary SO 2 NAAQS).


Hazardous Substances and Hazardous Waste Laws

On June 21, 2010, the US EPA published proposed regulations relating to coal combustion wastes. Two different proposed approaches are under consideration. The first approach, under which the US EPA would list these wastes as special wastes subject to regulation under Subtitle C of the Resource Conservation and Recovery Act (the section for hazardous wastes), could require EME to incur additional capital and operating costs. The second approach, under which the US EPA would regulate these wastes under Subtitle D of the Resource Conservation and Recovery Act (the section for nonhazardous wastes), is substantially similar to the requirements of existing regulations.


California Renewable Energy Developments

In June 2010, CARB released a proposed Renewable Electricity Standard regulation, which would require most retail sellers of electricity in California to procure 33% of their electricity from eligible renewable energy resources by 2020. The California legislature is also contemplating legislation to adopt a 33% renewables portfolio standard that may supersede the CARB regulation and impose its own program structure. Due to the possibility of legislation, the CARB has postponed voting on its proposed regulation until September 2010 at the Governor's request. SCE believes that achieving a 33% renewables portfolio standard in this timeframe will be highly ambitious, given the magnitude of the infrastructure build-out required and the slow pace of transmission permitting and approvals.


Once-Through Cooling

In May 2010, the California State Water Resources Board issued a final policy, which establishes closed-cycle wet cooling as required technology for retrofitting existing once-through cooled plants like San Onofre and many of the existing fossil-fueled power plants along the California coast. The final policy requires an independent engineering study to be conducted regarding the feasibility of compliance by California's two coastal nuclear power plants. Depending on the results of the study, the required compliance may result in significant capital expenditures at San Onofre and may affect its operations. It may also significantly impact SCE's ability to procure generating capacity from fossil-fueled plants that use ocean water in once-through cooling systems, system reliability and the cost of electricity to the extent other coastal power plants in California are forced to shut down or limit operations. The policy has the potential to adversely affect California's nineteen once-through cooled power plants, which provide over 21,000 MW of combined, in-state generation capacity, including over 9,100 MW of capacity interconnected within SCE's service territory.


Environmental Remediation

Edison International records its environmental remediation liabilities when site assessments and/or remedial actions are probable and a range of reasonably likely cleanup costs can be estimated. Edison International reviews its sites and measures the liability quarterly, by assessing a range of reasonably likely costs for each identified site using currently available information, including existing technology, presently enacted laws and regulations, experience gained at similar sites, and the probable level of involvement and financial condition of other potentially responsible parties. These estimates include

29


Table of Contents


costs for site investigations, remediation, operations and maintenance, monitoring and site closure. Unless there is a probable amount, Edison International records the lower end of this reasonably likely range of costs (reflected in "Other long-term liabilities") at undiscounted amounts.

As of June 30, 2010, Edison International's recorded estimated minimum liability to remediate its 28 identified sites at SCE (23 sites) and EME (5 sites primarily related to Midwest Generation) was $41 million, of which $38 million was related to SCE. Edison International's other subsidiaries have no identified remediation sites. The ultimate costs to clean up Edison International's identified sites may vary from its recorded liability due to numerous uncertainties inherent in the estimation process, such as: the extent and nature of contamination; the scarcity of reliable data for identified sites; the varying costs of alternative cleanup methods; developments resulting from investigatory studies; the possibility of identifying additional sites; and the time periods over which site remediation is expected to occur. Edison International believes that, due to these uncertainties, it is reasonably possible that cleanup costs at these identified sites could exceed its recorded liability by up to $223 million, all of which is related to SCE. The upper limit of this range of costs was estimated using assumptions least favorable to Edison International among a range of reasonably possible outcomes. In addition to its identified sites (sites in which the upper end of the range of costs is at least $1 million), SCE also has 34 immaterial sites for which total liability ranges from $5 million (the recorded minimum liability) to $10 million.

The CPUC allows SCE to recover 90% of its environmental remediation costs at certain sites, representing $32 million of its recorded liability, through an incentive mechanism (SCE may request to include additional sites). Under this mechanism, SCE will recover 90% of cleanup costs through customer rates; shareholders fund the remaining 10%, with the opportunity to recover these costs from insurance carriers and other third parties. SCE has successfully settled insurance claims with all responsible carriers. SCE expects to recover costs incurred at its remaining sites through customer rates. SCE has recorded a regulatory asset of $39 million for its estimated minimum environmental-cleanup costs expected to be recovered through customer rates.

Edison International's identified sites include several sites for which there is a lack of currently available information, including the nature and magnitude of contamination, and the extent, if any, that Edison International may be held responsible for contributing to any costs incurred for remediating these sites. Thus, no reasonable estimate of cleanup costs can be made for these sites.

SCE expects to clean up its identified sites over a period of up to 30 years. Remediation costs in each of the next several years are expected to range from $3 million to $18 million. Recorded costs were $3 million and $2 million for the three months ended June 30, 2010 and 2009, respectively, and were $3 million and $5 million for the six months ended June 30, 2010 and 2009, respectively.

Based on currently available information, Edison International believes it is unlikely that it will incur amounts in excess of the upper limit of the estimated range for its identified sites and, based upon the CPUC's regulatory treatment of environmental remediation costs incurred at SCE, Edison International believes that costs ultimately recorded will not materially affect its results of operations, financial position or cash flows. There can be no assurance, however, that future developments, including additional information about existing sites or the identification of new sites, will not require material revisions to such estimates.

Federal and State Income Taxes

Edison International's federal income tax returns are currently under examination by the IRS for tax years 2003 through 2006 and are subject to examination through tax year 2009. Edison International's California state income tax returns are subject to examination for tax years 1991 through 2009.


2010 FERC Rate Case

In September 2009, the FERC issued an order allowing SCE to implement its proposed 2010 rates effective March 1, 2010, subject to refund. The proposed rates would increase SCE's FERC revenue requirement by $107 million, or 24%, over the 2009 FERC revenue requirement primarily due to an increase in transmission rate base, and would result in an approximate 1% increase to SCE's overall system average rate. SCE has terminated settlement negotiations and begun the litigation process for the proposed 2010 rates. A final decision is expected in the second half of 2011.


FERC Transmission Incentives and CWIP Proceedings

In November 2007, the FERC issued an order granting ROE incentive adders, recovery of the ROE and incentive adders in the CWIP proceedings, and 100% recovery of abandoned plant costs (if any) for three of SCE's transmission projects: 125 basis point adder for both DPV2 and Tehachapi, and a 75 basis point adder for Rancho Vista. The CPUC filed an appeal of this order, which had been stayed pending final resolution by the FERC of the 2008 CWIP proceeding. In April 2010, the FERC issued an order on SCE's 2008 CWIP proceeding. The order sets SCE's 2008 base ROE (before incentives) at 9.54% and establishes a methodology for determining the base ROE for 2009 and 2010 CWIP incentives. In June 2010, SCE filed an application for rehearing with the FERC. The order did not have a material impact on SCE's earnings or cash flows. The outcomes of the 2009 and 2010 CWIP proceedings are still pending. SCE began collecting the 2010 CWIP revenue requirements in rates on June 1, 2010. The collected 2008 through 2010 CWIP revenue requirements are subject to refund, pending a final FERC order on these matters.


Homer City New Source Review Notice of Violation

Recent Developments

In May 2010, Homer City received an NOV from the US EPA. The new NOV alleges claims similar to those in the 2008 NOV, but it adds non-attainment NSR requirements to the alleged PSD violations. It also adds two prior owners of the Homer City facilities as parties.

In July 2010, Homer City received a 60-day Notice of Intent to Sue signed by the State of New York and the PADEP, stating their intent to file a citizen suit based on the same or similar theories advanced by the US EPA in the NOV. The Notice of Intent to Sue also named the sale-leaseback owner participants of the Homer City facilities, Homer City's general partner and limited partner, and two prior owners of the Homer City facilities.


Background

In June 2008, Homer City received an NOV from the US EPA alleging that, beginning in 1988, Homer City (or former owners of the Homer City facilities) performed repair or replacement projects at Homer City Units 1 and 2 without first obtaining construction permits as required by the PSD requirements of the CAA. The US EPA also alleges that Homer City has failed to file timely and

31


Table of Contents


complete Title V permits. The NOV does not specify the penalties or other relief that the US EPA seeks for the alleged violations. On June 30, 2009 and January 2, 2010, the US EPA issued requests for information to Homer City under Section 114 of the CAA. Homer City is working on a response to the requests. Homer City has met with the US EPA and has expressed its intent to explore the possibility of a settlement. If no settlement is reached and the DOJ files suit, litigation could take many years to resolve the issues alleged in the NOV. EME cannot predict the outcome of this matter or estimate the impact on its facilities, its results of operations, financial position or cash flows.

Homer City has sought indemnification for liability and defense costs associated with the NOV from the sellers under the asset purchase agreement pursuant to which Homer City acquired the Homer City facilities. The sellers responded by denying the indemnity obligation, but accepting a portion of defense costs related to the claims.

Homer City notified the sale-leaseback owner participants of the Homer City facilities of the NOV under the operative indemnity provisions of the sale-leaseback documents. The owner participants of the Homer City facilities, in turn, sought indemnification and defense from Homer City for costs and liabilities associated with the Homer City NOV. Homer City responded by recognizing its indemnity obligation and defense of the claims on terms consistent with its contractual obligations.


Midwest Generation New Source Review Lawsuit

Recent Developments

In March 2010, the Federal District Court for the Northern District of Illinois dismissed nine of the ten counts related to PSD requirements in the complaint filed by the US EPA and the State of Illinois against Midwest Generation, holding that, as a subsequent owner, Midwest Generation could not be held liable under the PSD provisions for modifications allegedly made by Commonwealth Edison, the prior owner of the Midwest Generation plants. The Court also dismissed the tenth count to the extent it sought civil penalties under the CAA, as barred by the applicable statute of limitations. The decision did not address (i) 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 or (ii) the complaint in intervention filed by a group of Chicago-based environmental action groups, which also alleges opacity and particulate matter violations.

In April 2010, the US EPA formally issued to EME the same NOV that was issued to Midwest Generation in 2007. The transmittal letter stated that the action was based on a review of the asset purchase agreement for the Midwest Generation plants and that the NOV was being issued to EME as a successor in interest to Commonwealth Edison.

In June 2010, the US EPA, the State of Illinois, and several the environmental groups filed amended complaints in the New Source Review litigation. The amended complaints are similar to the prior complaints, but seek to add Commonwealth Edison and EME as defendants and introduce new legal theories to impose liability on Midwest Generation and EME. An August status hearing has been scheduled, at which time a schedule for responses -to the amended complaints and other procedural matters will be determined.


Background

In August 2007, Midwest Generation received an NOV from the US EPA alleging that, beginning in the early 1990s and into 2003, Midwest Generation or Commonwealth Edison performed repair or

32


Table of Contents


replacement projects at six Illinois coal-fired electric generating stations in violation of the PSD requirements and of the New Source Performance Standards of the CAA, including alleged requirements to obtain a construction permit and to install controls sufficient to meet BACT emissions 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. At approximately the same time, Commonwealth Edison received an NOV substantially similar to the Midwest Generation NOV. Midwest Generation, Commonwealth Edison, the US EPA, and the DOJ, along with several Chicago-based environmental action groups, had discussions designed to explore the possibility of a settlement but no settlement resulted.

In August 2009, the US EPA and the State of Illinois filed a complaint in the Northern District of Illinois against Midwest Generation, but not Commonwealth Edison, alleging claims substantially similar to those in the NOV. 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 emissions 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 those required under the CPS. By order dated January 19, 2010, the Court allowed a group of Chicago-based environmental action groups to intervene in the case.

The owner participants of the Powerton and Joliet Stations have sought indemnification and defense from Midwest Generation and/or EME for costs and liabilities associated with these matters. EME responded by recognizing its indemnity obligation and defense of the claims on terms consistent with its contractual obligations.

An adverse decision could involve penalties and remedial actions that would have a material adverse impact on the financial condition and results of operations of EME. EME cannot predict the outcome of these matters or estimate the impact on its facilities, its results of operations, financial position or cash flows.


Navajo Nation Litigation

The Navajo Nation filed a complaint in June 1999 against SCE, among other defendants, arising out of the coal supply agreement for Mohave. Subsequently, the Hopi Tribe was added as an additional plaintiff. As amended in April 2010, the Navajo Nation's complaint asserts claims for, among other things, interference with fiduciary duties and contractual relations, fraudulent misrepresentations by nondisclosure, and various contract-related claims. The complaint claims that the defendants' actions prevented the Navajo Nation from obtaining the full value in royalty rates for the coal supplied to Mohave. The complaint seeks damages of not less than $600 million, plus interest thereon, and punitive damages of not less than $1 billion. In April 2009, in a related case filed in December 1993 against the U.S. Government, the U.S. Supreme Court found that the Navajo Nation did not have a claim for compensation. No trial date has been set for this litigation. SCE cannot predict the outcome of the Tribes' complaints against SCE.

Nuclear Insurance

Federal law limits public liability claims from a nuclear incident to the amount of available financial protection, which is currently approximately $12.6 billion. SCE and other owners of San Onofre and Palo Verde have purchased the maximum private primary insurance available ($375 million). The balance is covered by a loss sharing program among nuclear reactor licensees. If a nuclear incident at any licensed reactor in the United States results in claims and/or costs which exceed the primary insurance at that plant site, all nuclear reactor licensees could be required to contribute their share of the liability in the form of a deferred premium.

Based on its ownership interests, SCE could be required to pay a maximum of approximately $235 million per nuclear incident. However, it would have to pay no more than approximately $35 million per incident in any one year. If the public liability limit above is insufficient, federal law contemplates that additional funds may be appropriated by Congress. This could include an additional assessment on all licensed reactor operators as a measure for raising further federal revenue.

Property damage insurance covers losses up to $500 million, including decontamination costs, at San Onofre and Palo Verde. Decontamination liability and property damage coverage exceeding the primary $500 million also has been purchased in amounts greater than federal requirements. Additional insurance covers part of replacement power expenses during an accident-related nuclear unit outage. A mutual insurance company owned by entities with nuclear facilities issues these policies. If losses at any nuclear facility covered by the arrangement were to exceed the accumulated funds for these insurance programs, SCE could be assessed retrospective premium adjustments of up to approximately $43 million per year. Insurance premiums are charged to operating expense.


Spent Nuclear Fuel

Under federal law, the DOE is responsible for the selection and construction of a facility for the permanent disposal of spent nuclear fuel and high-level radioactive waste. The DOE did not meet its contractual obligation to begin acceptance of spent nuclear fuel by January 31, 1998. Extended delays by the DOE have led to the construction of costly alternatives and associated siting and environmental issues. Currently, both San Onofre and Palo Verde have interim storage for spent nuclear fuel on site sufficient for the current license period.

In January 2004, SCE, as operating agent, filed a complaint against the DOE in the United States Court of Federal Claims seeking damages for the DOE's failure to meet its obligation to begin accepting spent nuclear fuel from San Onofre. In June 2010, the United States Court of Federal Claims issued a decision granting SCE damages of approximately $142 million to recover costs incurred through December 31, 2005. Additional legal action would be necessary to recover damages incurred after that date. The decision is subject to appeal by the DOE. Any damages recovered would be returned to SCE ratepayers or used to offset past or future fuel decommissioning or storage costs for the benefit of the ratepayer.

Included in accumulated other comprehensive income at June 30, 2010 was $60 million, net of tax, in unrealized gains on EMG's commodity-based cash flow hedges; and a $10 million, net of tax, unrealized loss related to interest rate hedges. EMG's 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 $67 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 revenue 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. The maximum period over which a commodity cash flow hedge is designated is through December 31, 2012.

Note 10. 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 for a liability should reflect the entity's nonperformance risk. Fair value is determined using a hierarchy to prioritize the inputs to valuation models. The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are:

Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities;

Level 2—Pricing inputs that 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; and

Level 3—Prices or valuations that require inputs that are both significant to the fair value measurements and unobservable.

Edison International's assets and liabilities carried at fair value primarily consist of derivative contracts, SCE nuclear decommissioning trust investments and money market funds. Derivative contracts are primarily commodity contracts for the purchase and sale of power and gas and include contracts for forward physical sales and purchases, options and forward price swaps which settle only on a financial basis (including futures contracts). Derivative contracts can be exchange or over-the-counter traded.

The fair value of derivative contracts takes into account quoted market prices, time value of money, volatility of the underlying commodities and other factors. Derivatives that are exchange traded in active markets for identical assets or liabilities are classified as Level 1. Investments in money market funds are generally classified as Level 1, as fair value is determined by observable market prices in active markets.

EMG's derivative contracts, valued based on forward market prices in active markets (PJM West Hub, Northern Illinois Hub peak and AEP/Dayton) adjusted for nonperformance risks, are classified as Level 2. EMG obtains forward market prices from traded exchanges (Intercontinental Exchange Futures U.S. or New York Mercantile Exchange) and available broker quotes. Then, EMG selects a primary source that best represents traded activity for each market to develop observable forward market prices in determining the fair value of these positions. 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 that EMG believes to provide the most liquid market for the commodity. EMG considers broker quotes to be observable when corroborated with other information which may include a combination of prices from exchanges, other brokers and comparison to executed trades.

SCE's Level 2 derivatives primarily consist of natural gas financial swaps and natural gas physical trades for which SCE obtains the applicable Henry Hub, basis, index, or forward market prices from the New York Mercantile Exchange and Intercontinental Exchange.

Level 3 includes the majority of SCE's derivatives, including over-the-counter options, bilateral contracts, capacity contracts, and QF contracts. The fair value of these derivatives is determined using

37


Table of Contents


uncorroborated non-binding broker quotes (from one or more brokers) and models which may require SCE 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.

Level 3 also includes derivatives that trade infrequently (such as firm transmission rights and CRRs in the California market, financial transmission rights traded in markets outside California and over-the-counter derivatives at illiquid locations) and long-term power agreements. For illiquid financial transmission rights and CRRs, 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.

Changes in fair values are based on the hypothetical sale of illiquid positions. 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. In circumstances where Edison International 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, Edison International continues to assess valuation methodologies used to determine fair value. Derivative contracts with counterparties that have significant nonperformance risks are classified as Level 3.

In assessing nonperformance risks, Edison International reviews credit ratings of counterparties (and related default rates based on such credit ratings) and prices of credit default swaps. The market price (or premium) for credit default swaps represents the price that a counterparty would pay to transfer the risk of default, typically bankruptcy, to another party. A credit default swap is not directly comparable to the credit risks of derivative contracts, but provides market information of the related risk of nonperformance. The fair value of derivative assets and derivative liabilities nonperformance risk was $4 million and $9 million, respectively, at June 30, 2010 and was $4 million and $7 million, respectively, at December 31, 2009.

The SCE nuclear decommissioning trust investments include equity securities, U.S. treasury securities and other fixed-income securities. Equity and treasury securities are classified as Level 1 as fair value is determined by observable market prices in active or highly liquid and transparent markets. The remaining fixed-income securities are classified as Level 2. The fair value of these financial instruments is based on evaluated prices that reflect significant observable market information such as reported trades, actual trade information of similar securities, benchmark yields, broker/dealer quotes, issuer spreads, bids, offers and relevant credit information.

Amounts reported in "Competitive power generation" revenue on Edison International's consolidated statements of income were $(2) million and $13 million for the three months ended June 30, 2010 and 2009, respectively, and were $32 million and $71 million for the six months ended June 30, 2010 and 2009, respectively. The remainder of the unrealized gains and losses relate to SCE. See (2) above.

There were no significant transfers between levels during the first six months of 2010. Edison International determines the fair value for transfers in and transfers out of each level as of the end of each reporting period.


Nuclear Decommissioning Trusts

SCE is collecting in rates amounts for the future costs of removal of its nuclear assets, and has placed those amounts in independent decommissioning trusts. Contributions are approximately $46 million per year. Funds collected, together with accumulated earnings, will be utilized solely for decommissioning. The CPUC has set certain restrictions related to the investments of these trusts.

Note 13. Variable Interest Entities

Effective January 1, 2010, Edison International adopted the FASB's new guidance regarding variable interest entities ("VIEs"). A VIE is defined as a legal entity whose equity owners do not have sufficient equity at risk, or, as a group, the holders of the equity investment at risk lack any of the following three characteristics: decision-making rights, the obligation to absorb losses, or the right to receive the expected residual returns of the entity. The new guidance replaces the predominantly quantitative

44


Table of Contents


model for determining which reporting entity, if any, has a controlling financial interest in a VIE with a qualitative approach. Under this new qualitative model, the primary beneficiary is identified as the variable interest holder that has both the power to direct the activities of the VIE that most significantly impact the entity's economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. The primary beneficiary is required to consolidate the VIE unless specific exceptions or exclusions are met. Commercial and operating activities are generally the factors that most significantly impact the economic performance of VIEs in which Edison International has a variable interest. Commercial and operating activities include construction, operation and maintenance, fuel procurement, dispatch and compliance with regulatory and contractual requirements.


Projects or Entities that are Consolidated

At June 30, 2010 and December 31, 2009, EMG had majority interests in 15 wind projects with a total generating capacity of 701 MW that have minority interests held by others. The projects are located in Iowa, Minnesota, New Mexico, Nebraska and Texas. As of December 31, 2009, all of these projects were consolidated by EMG. Upon the application of the new guidance effective January 1, 2010, EMG deconsolidated two of these projects. See further discussion in "—Variable Interests in VIEs that are not Consolidated—Equity Interests." In determining that EMG was the primary beneficiary of the 13 projects consolidated at June 30, 2010, the key factors considered were EMG's ability to direct commercial and operating activities and EMG's obligation to absorb losses and right to receive benefits that could potentially be significant to the variable interest entities.

The following table presents summarized financial information of the wind projects that had minority interests held by others and were consolidated by Edison International:

Amounts included assets of $253 million ($247 million of net property, plant and equipment) that were deconsolidated on January 1, 2010.

Assets serving as collateral for the debt obligations had a carrying value of $79 million and $81 million at June 30, 2010 and December 31, 2009, respectively, and primarily consist of property, plant and equipment.

EMG has a 50% partnership interest in the Ambit project. EMG has the power to direct the commercial and operating activities of the project pursuant to the existing contracts and has the obligation to absorb losses and right to receive benefits from the project. Therefore, under the new

45


Table of Contents


guidance, EMG is the primary beneficiary which resulted in the consolidation of the Ambit project by Edison International. Total assets consolidated at January 1, 2010 and June 30, 2010 were $99 million and $100 million, respectively. Substantially all of the assets of the Ambit project are pledged as collateral for the partnership's debt obligations.


Variable Interests in VIEs that are not Consolidated

Power Purchase Contracts

SCE has power purchase agreements ("PPAs") in which it has a variable interest in 17 VIEs, including 6 tolling agreements where SCE provides the natural gas to operate the plants and 11 contracts with QFs (including the Big 4 projects) that contain variable pricing provisions based on the price of natural gas. SCE has concluded that it is not the primary beneficiary of these VIEs since it does not control the commercial and operating activities of these entities. In general, because payments for capacity are the primary source of income, the most significant economic activity for SCE's VIEs is the operation and maintenance of the power plants. SCE does not have control over the operation and maintenance of the facilities considered VIEs and it does not bear operational risk of the facilities. See further discussion of the Big 4 projects below.

As of the balance sheet date, the carrying amount of assets and liabilities in SCE's consolidated balance sheet that relate to its involvement with VIEs result from amounts due under the PPAs or the fair value of those derivative contracts, which are accounted for at fair value. See Note 10 for a discussion on nonperformance risk. Further, SCE has no residual interest in the entities and has not provided or guaranteed any debt or equity support, liquidity arrangements, performance guarantees or other commitments associated with these contracts other than the purchase commitments described in Note 6. The aggregate capacity dedicated to SCE for these VIE projects was 1,749 MW at June 30, 2010 and the amounts that SCE paid to these projects were $117 million and $115 million for the three months ended June 30, 2010 and 2009, respectively, and $242 million and $231 million for the six months ended June 30, 2010 and 2009, respectively. These amounts are recoverable in customer rates.

Realized and unrealized losses are recovered or expected to be recovered from ratepayers in rates, subject to reasonableness, and therefore are not reflected in earnings.


Equity Interests

EMG accounts for domestic energy projects where EMG has a 50% or less ownership interest and cannot exercise unilateral control under the equity method. As of June 30, 2010 and December 31, 2009, EMG had significant variable interests in projects that are not consolidated consisting of the Big 4 projects and the Sunrise project. A subsidiary of EMG operates the Big 4 projects and EMG's partner provides the fuel management services. In addition, the executive director of these projects is provided by EMG's partner. Commercial and operating activities are jointly controlled by a management committee of each VIE. Accordingly, EMG continues to account for its variable interests under the equity method.

As noted previously in "Projects or Entities that are Consolidated," EMG deconsolidated two renewable wind energy generating facilities, the Elkhorn Ridge wind project and San Juan Mesa wind project, on January 1, 2010. The commercial and operating activities of these entities are directed by a management committee comprised of representatives of each partner. Thus, EMG is not the primary beneficiary of these projects. Accordingly, effective January 1, 2010, EMG accounts for its interests in these projects under the equity method.

The following table presents the carrying amount of EMG's investments in unconsolidated variable interest entities and the maximum exposure to loss for each investment as of June 30, 2010:

(in millions)

Exposure


(Unaudited)

Natural gas-fired projects

$ 325 $ 325

Wind projects

174 174

EMG'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. Two of EMG's domestic energy projects have long-term debt that is secured by a pledge of assets of the project entity, but does not provide for any recourse to EME. Accordingly, a default on a long-term financing of a project could result in foreclosure on the assets of the project entity resulting in a loss of some or all of EMG's investment, but would not require EMG to contribute additional capital. At June 30, 2010, entities which EMG has accounted for under the equity method had indebtedness of $143 million, of which $54 million is proportionate to EMG's ownership interest in these projects.

Table of Contents


Big 4 Projects Consolidated Prior to 2010

Edison International has variable interests in the Big 4 Projects through equity interests held by EMG and power contracts between SCE and the Big 4 Projects that contain variable contract pricing provisions based on the price of natural gas. Prior to 2010, Edison International had determined that SCE was the primary beneficiary of these four VIEs and, therefore, consolidated these projects. Edison International deconsolidated the Big 4 Projects at January 1, 2010 since it did not control the commercial and operating activities of these projects through EMG and SCE. Commercial and operating activities are jointly controlled by a management committee of each VIE. Therefore, neither EMG, SCE nor Edison International on a consolidated basis has control of the entities. In addition, EMG's partner provides the executive director and fuel management services and the steam supply is based on the needs of EMG's partner. The deconsolidation did not result in a gain or loss.

The following table presents the carrying amounts of VIEs consolidated by Edison International at December 31, 2009 (these balances were deconsolidated at January 1, 2010):

Note 14. Business Segments

Edison International's reportable business segments include its electric utility operation segment (SCE) and a competitive power generation segment (EMG). Prior to January 1, 2010, Edison International reported three business segments: electric utility operations segment, competitive power generation segment and financial services segment. As a result of termination of the cross-border leases during 2009 and the continued decline of the remaining portfolio of the financial services segment, the remaining business activity is no longer significant enough to report separately. Accordingly, the financial services segment has been combined into the competitive power generation segment for all periods presented. The combination of these business activities is consistent with the management structure of EMG and evaluation of performance by Edison International. The significant accounting policies of the segments are the same as those described in Note 1.

Table of Contents

Edison International's earnings are prepared in accordance with generally accepted accounting principles used in the United States. Management uses core earnings by principal operating subsidiary internally for financial planning and for analysis of performance. Core earnings by principal operating subsidiary are also used when communicating with analysts and investors regarding our earnings results to facilitate comparisons of the Company's performance from period to period. Core earnings are a non-GAAP financial measure and may not be comparable to those of other companies. Core earnings are defined as earnings attributable to Edison International shareholders excluding income or loss from discontinued operations and income or loss from significant discrete items that management does not consider representative of ongoing earnings, such as: settlement of prior year tax liabilities and change in tax law; exit activities, including lease terminations, asset impairments, sale of certain assets, early debt extinguishment costs and other activities that are no longer continuing; and non-recurring regulatory or legal proceedings.

SCE's 2010 core earnings increased $49 million and $44 million for the quarter and year-to-date, respectively. The quarter increase was due to lower income tax expense and higher authorized revenue to support rate base growth. These quarter increases were partially offset by higher operating expenses, including the impact of curtailed spending last year due to the timing of the 2009 CPUC GRC decision. The year-to-date increase was due to higher authorized revenue to support rate base growth, lower income tax expense and higher capitalized financing costs (AFUDC). These year-to-date increases were partially offset by higher operating expenses, including the impact of curtailed spending last year due to the timing of the 2009 CPUC GRC decision. The lower tax expense for the quarter and year-to-date includes a change in method of tax accounting for asset removal costs primarily related to SCE's infrastructure replacement program.

EMG's 2010 core earnings decreased $93 million and $80 million for the quarter and year-to-date, respectively. The decline in core earnings during the second quarter reflects increased coal fleet maintenance activities for scheduled plant outages, impact of unrealized gains and losses and lower generation. In addition, second quarter of 2009 results included $20 million after tax related to the sale of an interest in the Midlands Cogeneration Ventures leverage lease. In addition to the decrease in earnings attributable to the leverage lease transaction, the decrease in the six month results includes the higher scheduled outages during the second quarter, impact of unrealized gains and losses, and lower average realized energy prices. Partially offsetting these decreases in the six month results were higher trading revenues and distributions from two projects recorded in the first quarter.

Consolidated non-core items for Edison International included:

An earnings benefit of $138 million recorded in the second quarter of 2010 resulting from acceptance by the California Franchise Tax Board of the tax positions finalized with the IRS in 2009 as part of the Global Settlement for tax years 1986 through 2002 (described in "Item 8. Edison International Notes to Consolidated Financial Statements—Note 4. Income Taxes" of the 2009 Form 10-K) and revision to interest recorded on the federal Global Settlement. Edison International is awaiting receipt of final interest calculations from the California Franchise Tax Board.

A non-cash charge of $39 million in the first quarter of 2010 to reverse previously recognized federal tax benefits eliminated by the federal health care legislation. The Patient Protection and Affordable Care Act, as modified by the Health Care and Education Reconciliation Act, was enacted in March 2010. The new health care legislation includes a provision that eliminates the federal tax deduction of retiree health care costs to the extent those costs are eligible for federal Medicare Part D subsidies. Although this change does not take effect until January 1, 2013, Edison International is required to recognize the full accounting impact of the legislation in its financial statements in the period of enactment.

An after-tax earnings charge of $262 million and $274 million for the three- and six-month periods ended June 30, 2009, respectively, related to the Global Settlement with the IRS and termination of Edison Capital's cross-border leases ($920 million pre-tax loss).


SCE Capital Program

SCE's capital program continues to be focused primarily in five areas:

Upgrading and constructing new transmission lines to strengthen system reliability and increase access to renewable energy, including the Tehachapi, Devers-Colorado River and Eldorado-Ivanpah projects.

Maintaining reliability and expanding capability of SCE's transmission and distribution system.

Developing and installing up to 250 MW of utility-owned solar photovoltaic generating facilities (generally ranging in size from 1 to 2 MW each) on commercial and industrial rooftops and other space in SCE's service territory.

Replacing steam generators at San Onofre intended to enable operations until at least the end of its initial license period in 2022. During the first quarter of 2010, SCE completed the replacement of the steam generators at San Onofre Unit 2, which was returned to service on April 11, 2010. See "SCE: Results of Operations—Electric Utility Results of Operations—Utility Earning Activities" for discussion of the extended outage at San Onofre Unit 2.

Installing "smart" meters in approximately 5.3 million households and small businesses referred to as EdisonSmartConnect™. During the first six months of 2010, SCE installed approximately 860,000 smart meters, with cumulative installations totaling over 1 million.

SCE continues to plan to utilize cash generated from its operations and issuance of additional debt and preferred equity for its capital program. During the six months ended June 30, 2010, SCE issued long-term debt (see "SCE: Liquidity and Capital Resources—Historical Consolidated Cash Flow—Condensed Consolidated Statement of Cash Flows—Cash Flows Provided (Used) by Financing Activities" for further information).

SCE's capital investments (including accruals) during the six months ended June 30, 2010 totaled $1.5 billion. SCE projects that capital investments will be in the range of $3.3 billion to $4.0 billion in 2010 and the 2010 – 2014 total capital investment spending will be in the range of $18 billion to $21.5 billion. The rate of actual capital spending will be affected by permitting, regulatory, market and other factors as discussed further under "SCE: Liquidity and Capital Resources—Capital Investment Plans" in the 2009 Form 10-K.


SCE 2012 General Rate Case

On July 19, 2010, SCE submitted to the CPUC's Division of Ratepayer Advocates its notice of intent (NOI) to file a 2012 GRC. The NOI indicates that SCE's GRC application, expected to be filed by year-end 2010, will request a 2012 base rate revenue requirement of $6.3 billion. After considering the effects of sales growth, SCE's request would be a $903 million increase over projected 2011 base rate revenue. If the CPUC approves the requested rate increase and allocates the increase to ratepayer groups on a system average percentage change basis, the percentage increases over current base rates and total rates are estimated to be 16.9% and 7.9%, respectively. The requested revenue requirement increase is driven by the need to maintain system reliability, accommodate customer load growth, and

54


Table of Contents


increase operation and maintenance expenses primarily for capital-related projects, information technology, insurance and pension contributions. The NOI also indicates that SCE's application will propose a post-test year ratemaking mechanism which would result in 2013 and 2014 incremental base revenue requirement increases, net of sales growth, of $305 million and $542 million, respectively, for the same reasons. The current schedule anticipates a final decision on SCE's 2012 GRC by the end of 2011. SCE cannot predict the revenue requirement the CPUC will ultimately authorize or precisely when a final decision will be adopted.


Environmental Developments

Midwest Generation Environmental Compliance Plans and Costs

During the second quarter of 2010, Midwest Generation continued its permitting and planning activities for NO x and SO 2 controls to meet the requirements of the CPS. Midwest Generation has now received all necessary permits from the Illinois EPA allowing the installation of SNCR technology on multiple units to meet the NO x portion of the CPS.

In addition, work continued on the possible employment of FGD technology using dry scrubbing with sodium-based sorbents as a method to comply with the SO 2 portion of the CPS. Testing of this technology demonstrated significant reductions in SO 2 emissions when using the low-sulfur coal employed by Midwest Generation. Use of this technology in combination with low-sulfur coal is expected to require substantially less capital and installation time than the spray dryer absorber technology originally contemplated, but would likely result in higher ongoing operating costs and may consequently result in lower dispatch rates and competitiveness of Midwest Generation's plants. Also, the use of dry scrubbing with sodium-based sorbents to meet environmental regulations will likely require Midwest Generation to incur the costs of upgrading its particulate removal systems.

Based on this work, Midwest Generation estimates the cost of retrofitting all units, using dry scrubbing with sodium-based sorbents to comply with CPS requirements for SO 2 emissions, at approximately $1.2 billion in 2010 dollars. If completed, these expenditures would be incurred over multiple years. Midwest Generation expects to seek permits from the Illinois EPA for select units later this year.

Decisions regarding whether or not to proceed with the above projects or other approaches to compliance 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 shut down units, instead of installing controls, to be in compliance with the CPS, and, therefore, decisions about any particular combination of retrofits and shutdowns it may ultimately employ to comply with the CPS also remain subject to conditions applicable at the time decisions are required or made. Due to existing uncertainties about these factors, Midwest Generation may defer final decisions about particular units for the maximum time available. Accordingly, final decisions on whether to install controls, to install particular kinds of controls, and to actually expend capital that is budgeted may not occur until 2012 for some of the units and potentially later for others.


Environmental Regulation Developments

Greenhouse Gas Regulation Developments

In June 2010, the US EPA published its final greenhouse gas tailoring rule, with less stringent statutory emissions thresholds for greenhouse gases than those originally proposed in late 2009. Since the rule

55


Table of Contents


affects only new or modified sources, it is not expected to have any immediate effect on the fossil-fuel generating stations of SCE or EMG.


Transport Rule and Coal Combustion Waste Regulation

In June and July of 2010, two proposed rules were published. The first proposed rule, known as the Transport Rule (a replacement for the CAIR), would substantially reduce power plant emissions of NO x and SO 2 starting in 2012, with additional reductions in 2014, and would impose new limitations on emissions allowance trading. The second proposal relates to the handling of coal combustion wastes.


California Renewable Energy Developments

In June 2010, CARB released a proposed Renewable Electricity Standard regulation, which would require most retail sellers of electricity in California to procure 33% of their electricity from eligible renewable energy resources by 2020. The California legislature is also contemplating legislation to adopt a 33% renewables portfolio standard that may supersede the CARB regulation and impose its own program structure. SCE believes that achieving a 33% renewables portfolio standard in this timeframe will be highly ambitious, given the magnitude of the infrastructure build-out required and the slow pace of transmission permitting and approvals.

Once-Through Cooling

On May 4, 2010, the California State Water Resources Board issued a final policy, which establishes closed-cycle wet cooling as required technology for retrofitting existing once-through cooled plants like San Onofre and many of the existing fossil-fueled power plants along the California coast. The final policy requires an independent engineering study to be conducted regarding the feasibility of compliance by California's two coastal nuclear power plants. Depending on the results of the study, the required compliance may result in significant capital expenditures at San Onofre and may affect its operations. It may also significantly impact SCE's ability to procure generating capacity from fossil-fueled plants that use ocean water in once-through cooling systems, system reliability and the cost of electricity to the extent other coastal power plants in California are forced to shut down or limit operations.

For further description discussion, see "Edison International Notes to Consolidated Financial Statements—Note 6. Commitments and Contingencies—Contingencies—Environmental Developments."


EMG Renewable Program

EMG has four projects totaling 600 MW under construction. Included among the projects under construction is the 130 MW Taloga project, which is slated to utilize wind turbines that are subject to a legal dispute. EMG also had a development pipeline of potential wind projects with projected installed capacity of approximately 3,400 MW at June 30, 2010. EMG had a purchase contract for 69 MW of wind turbines, and 33 MW of wind turbines in storage, that are to be used for projects not yet under construction as of June 30, 2010, excluding turbine purchase contracts for 199 MW of wind turbines that are subject to a legal dispute. EMG has deferred delivery and payment for the 69 MW of turbines under the purchase contract to January 2011. If EMG is unable to develop such projects on acceptable terms and conditions, certain turbine orders may be terminated, which would result in a material charge. The pace of additional growth in EMG's renewables program will be subject to the availability of projects that meet EMG's requirements and the capital needed for development, which will be affected by the extent of internally generated cash flow and future decisions about capital expenditures for environmental compliance by its coal fleet. Consequently, pending substantial progress on or

56

financing of the environmental retrofits, growth of the renewables program may depend upon the availability of third-party financing.


Mitsubishi Lawsuit

EME filed a complaint in the Superior Court of the State of California against Mitsubishi Power Systems Americas, Inc. and Mitsubishi Heavy Industries, Ltd. with respect to a wind turbine generator supply agreement. Matters under dispute include, among other things, the requirement to purchase and pay the remaining purchase price for 199 MW of wind turbines, including related services and warranties, among other items, in the approximate amount of $289 million. The complaint asks the Court for, among other things, an order finding the supply agreement void and unenforceable and for an award of monetary damages, including return to EME of deposits of $68 million previously made for the units subject to dispute. See "Legal Proceedings" in Part II of this quarterly report.


Parent Company Liquidity

The parent company's liquidity and its ability to pay operating expenses and dividends to common shareholders have historically been dependent on dividends from SCE, tax-allocation payments under its tax-allocation agreements with its subsidiaries, and access to bank and capital markets. Given its subsidiaries' plans to use their cash flows for their respective capital needs, Edison International (parent) expects to incur additional borrowings to fund its dividends to common shareholders and operating expenses.

At June 30, 2010, Edison International (parent) had approximately $27 million of cash and equivalents. The following table summarizes the status of the Edison International (parent) credit facility at June 30, 2010:

SOUTHERN CALIFORNIA EDISON COMPANY

RESULTS OF OPERATIONS

SCE's results of operations are derived mainly through two sources:

Utility earning activities, which mainly represent CPUC- and FERC-authorized base rates, which allow a reasonable return, and CPUC-authorized incentive mechanisms; and

Utility cost-recovery activities, which mainly represent CPUC-authorized balancing accounts, which allow recovery of costs (including carrying costs) incurred or provide mechanisms to track and recover or refund differences in forecasted and actual amounts. Balancing accounts (except for certain capital-related projects) do not allow for a return.

Utility earning activities include base rates that are designed to recover forecasted operation and maintenance costs, certain capital-related carrying costs, interest, taxes and a return, including the return and taxes on capital projects recovered through balancing account mechanisms. Differences between authorized and actual results impact earnings. Also included in utility earning activities are revenues or penalties related to incentive mechanisms, other operating revenue, and regulatory charges or disallowances, if any.

Utility cost-recovery activities include rates which provide for recovery, subject to reasonableness review, of fuel costs, purchased power costs, certain operation and maintenance expenses (including public purpose related program costs), and depreciation expense related to certain projects. There is no return earned on cost-recovery expenses.


Electric Utility Results of Operations

Utility Earning Activities

Utility earning activities were primarily affected by the following:

Higher operating revenue of $55 million primarily due to the following:

$40 million increase related to implementation of the 2009 GRC (effective January 1, 2009) which authorized a 4.25% increase in 2010 authorized revenue.

$15 million increase related to revenue requirements for capital projects recovered through CPUC-authorized balancing accounts primarily related to the steam generator replacement project and the EdisonSmartConnect TM project.

$5 million increase related to the 2009 and 2010 FERC rate cases effective March 1, 2009 and March 1, 2010, respectively (see "SCE: Liquidity and Capital Resources—Regulatory Proceedings—2010 FERC Rate Case" for further discussion).

Higher operation and maintenance expense of $21 million including the impact of curtailed spending last year due to the timing of the 2009 GRC decision. The increase in operation and maintenance expense was primarily in the following areas:

$15 million of higher transmission and distribution expenses. In addition to the impact of curtailed spending, the 2010 increase reflects higher costs to support system reliability and infrastructure replacement, increases in preventive maintenance work and training costs.

$10 million of higher expenses related to higher general liability insurance, a nuclear insurance refund received in 2009, and higher injury and damage claims.

Partially offset by:

    $10 million of lower generation expenses primarily related to a $15 million hydrogen energy project payment made in the second quarter of 2009, which was subsequently approved for balancing account treatment in December 2009.

Higher depreciation expense of $31 million primarily resulting from increased capital investments including capitalized software costs.

See "—Income Taxes" below for discussion of lower income taxes during the three months ended June 30, 2010 compared to the same period in 2009.


Utility Cost-Recovery Activities

Excluding the impact of deconsolidation of the Big 4 projects (see "Edison International Notes to Consolidated Financial Statements Note 13. Variable Interest Entities"), utility cost-recovery activities were primarily affected by:

Higher purchased power expense of $29 million primarily due to: higher QF purchased power expense of $120 million primarily due to higher natural gas prices and higher kWh purchases. This was partially offset by lower bilateral energy purchase expense of $30 million primarily due to decreased kWh purchases. Realized losses on economic hedging activities were $38 million in 2010

60


Table of Contents

    and $96 million in 2009. Changes in realized losses on economic hedging activities were primarily due to settled natural gas prices being lower than contract prices.

Higher fuel expense of $14 million primarily due to higher costs at Mountainview of $15 million resulting from higher natural gas prices.

Utility Earning Activities

Utility earning activities were primarily affected by the following:

Higher operating revenue of $116 million primarily due to the following:

$80 million increase related to implementation of the 2009 GRC (effective January 1, 2009) which authorized a 4.25% increase in 2010 authorized revenue.

61


Table of Contents

    $30 million increase related to the 2009 and 2010 FERC rate cases effective March 1, 2009 and March 1, 2010, respectively (see "SCE: Liquidity and Capital Resources—Regulatory Proceedings—2010 FERC Rate Case" for further discussion).

    $15 million increase related to revenue requirements for capital projects recovered through CPUC-authorized balancing accounts primarily related to the steam generator replacement project and the EdisonSmartConnect TM project.

Higher operation and maintenance expense of $99 million including the impact of curtailed spending last year due to the timing of the 2009 GRC decision. The increase in operation and maintenance expense was primarily in the following areas:

$45 million of higher transmission and distribution expenses. In addition to the impact of curtailed spending, the 2010 increase reflects higher costs to support system reliability and infrastructure replacement, increases in preventive maintenance work, line clearing costs and training costs.

$30 million of higher expenses related to higher general liability insurance, a nuclear insurance refund received in 2009, and higher injury and damage claims.

$5 million of higher 2010 generation expenses reflecting $10 million primarily due to additional work identified during the San Onofre Unit 2 scheduled outage and $10 million primarily due to overhaul and outage costs at Four Corners. These increases were partially offset by a $15 million hydrogen energy project payment made in the second quarter of 2009, which was subsequently approved for balancing account treatment in December 2009. During the San Onofre Unit 2 scheduled outage, SCE identified and completed additional work unrelated to the steam generator replacement that resulted in increased operation and maintenance expense and extended the outage beyond SCE's initial estimated timeframe. San Onofre Unit 2 was returned to service on April 11, 2010.

The first two of the four replacement steam generators were installed in San Onofre Unit 2 in the first quarter of 2010 and the installation of the final two steam generators at San Onofre Unit 3 is expected to begin in late 2010. The CPUC has previously adopted a mechanism establishing thresholds for recovery of SCE's incurred costs for the steam generator replacements. Costs above an established threshold will require a reasonableness review. No cost recovery will be allowed for costs incurred that exceed an authorized cap. The determination of whether a reasonableness review of costs is necessary will be made after the steam generator replacement project is completed.

As discussed in the 2009 Form 10-K, SCE is subject to the jurisdiction of the NRC with respect to its San Onofre and Palo Verde Nuclear Generating Stations. San Onofre is currently addressing a number of regulatory and performance issues, and the NRC has required SCE to take actions to provide greater assurance of compliance by San Onofre personnel with applicable NRC requirements and procedures. SCE continues to implement plans to address the identified issues. The NRC has continued to affirm that San Onofre has been operated and is being operated safely; however, a number of these issues remain outstanding, and additional issues have been identified. The cumulative impact of these regulatory and performance issues has been an increase in management focus and other resources applied at San Onofre. To the extent that these issues persist, the likelihood of further required action, and associated potential for effects on costs and operations, will increase.

62


Table of Contents

Higher depreciation expense of $57 million primarily related to increased capital investments including capitalized software costs.

Lower net interest expense and other of $12 million primarily related to higher capitalized cost of equity and debt (AFUDC) resulting from a higher capitalization rate and level of construction in progress. See "Edison International Notes to Consolidated Financial Statements Note 12. Other Income and Expenses" for further detail of other income and expenses.

See "—Income Taxes" below for discussion of lower income taxes during the six months ended June 30, 2010 compared to the same period in 2009.


Utility Cost-Recovery Activities

Excluding the impact of deconsolidation of the Big 4 projects (see "Edison International Notes to Consolidated Financial Statements Note 13. Variable Interest Entities"), utility cost-recovery activities were primarily affected by:

Higher purchased power expense of $96 million primarily related to: higher QF purchased power expense of $250 million primarily due to higher natural gas prices and higher kWh purchases; and higher ISO-related energy costs of $75 million, including replacement power costs related to the San Onofre Unit 2 scheduled outage. This was partially offset by lower bilateral energy purchase expense of $90 million primarily due to decreased kWh purchases. Realized losses on economic hedging activities were $62 million in 2010 and $194 million in 2009. Changes in realized losses on economic hedging activities were primarily due to settled natural gas prices being lower than contract prices.

Lower fuel expense of $4 million primarily related to lower costs at Four Corners (coal) of $10 million and lower costs at San Onofre Unit 2 of $5 million both resulting from the outages described above. These decreases were offset by higher costs at Mountainview of $15 million resulting from higher natural gas prices.


Supplemental Operating Revenue Information

SCE's total consolidated operating revenue was $2.2 billion and $2.3 billion for the three months ended June 30, 2010 and 2009, respectively, of which $2.4 billion and $2.3 billion was related to retail billed and unbilled revenue (excluding wholesale sales and balancing account (over)/undercollections) for the same respective periods. SCE's total consolidated operating revenue was $4.4 billion and $4.5 billion for the six months ended June 30, 2010 and 2009, respectively, of which $4.4 billion and $4.2 billion was related to retail billed and unbilled revenue (excluding wholesale sales and balancing account (over)/undercollections) for the same respective periods. Retail billed and unbilled revenue increased $57 million and $201 million for the three- and six-month periods ended June 30, 2010, respectively, compared to the same periods in 2009. The quarter and year-to-date increases reflect a rate increase of $126 million and $305 million, respectively, and a sales volume decrease of $69 million and $104 million, respectively. The rate increase was due to higher system average rates for 2010 compared to the same periods in 2009 mainly due to the implementation of the 2009 CPUC GRC decision and approved FERC transmission rate changes. The sales volume decrease was due to slightly milder weather experienced during the second quarter of 2010 compared to the same period in 2009 and economic conditions. As a result of the CPUC-authorized decoupling mechanism, SCE does not bear the volumetric risk related to electricity sales (see "Overview of Ratemaking Mechanisms" in the 2009 Form 10-K).

Due to warmer weather during the summer months and SCE's rate design, operating revenue during the third quarter of each year is generally higher than other quarters.

Amounts SCE bills and collects from its customers for electric power purchased and sold by the CDWR to SCE's customers, CDWR bond-related costs and a portion of direct access exit fees are remitted to the CDWR and are not recognized as revenue by SCE. The amounts collected and remitted to CDWR were $286 million and $582 million for the three- and six-month periods ended June 30, 2010, respectively, and $391 million and $896 million for the three- and six-month periods ended June 30, 2009, respectively. Effective January 1, 2010, the CDWR-related rates were decreased primarily to refund CDWR overcollections to customers.


Income Taxes

SCE's income tax expense from continuing operations increased $203 million and $211 million during the three- and six-month periods ended June 30, 2010, respectively. The 2010 income tax expense reflects: a $39 million non-cash charge recorded in the first quarter related to the federal health care legislation enacted in March 2010; a $40 million earnings benefit due to a change in method of tax accounting for asset removal costs primarily related to SCE's infrastructure replacement program; and a $53 million earnings benefit recorded in the second quarter resulting from acceptance by the California Franchise Tax Board of the tax positions finalized with the IRS in 2009 as part of the Global Settlement for tax years 1986 through 2002. During the second quarter of 2009, SCE recognized a $300 million earnings benefit related to the federal Global Settlement finalized with the IRS. See "Edison International Notes to Consolidated Financial Statements—Note 4. Income Taxes" for further discussion.


LIQUIDITY AND CAPITAL RESOURCES

SCE expects to fund its continuing obligations and projected capital investments for 2010 through cash and equivalents on hand, operating cash flows and incremental capital market financings of debt and preferred equity. SCE also has availability under its credit facilities if additional funding and liquidity are necessary to meet operating and capital requirements.


Available Liquidity

As of June 30, 2010, SCE had approximately $91 million of cash and equivalents and short-term investments. As of June 30, 2010, SCE's long-term debt, including current maturities of long-term debt, was $7.1 billion.

Debt Covenant

SCE has a debt covenant in its credit facilities that limits its debt to total capitalization ratio to less than or equal to 0.65 to 1. At June 30, 2010, SCE's debt to total capitalization ratio was 0.46 to 1.


Regulatory Proceedings

Energy Efficiency Risk/Reward Incentive Mechanism

As discussed in the year-ended 2009 MD&A, the CPUC adopted an Energy Efficiency Risk/Reward Incentive Mechanism applicable to the 2006 – 2008 performance period under which SCE expected to receive a $27 million final payment in late 2010. SCE expects a CPUC decision on the final payment, if any, in the second half of 2010. There is no assurance that SCE will receive a final payment.


2010 FERC Rate Case

In September 2009, the FERC issued an order allowing SCE to implement its proposed 2010 rates effective March 1, 2010, subject to refund. The proposed rates would increase SCE's FERC revenue requirement by $107 million, or 24%, over the 2009 FERC revenue requirement primarily due to an increase in transmission rate base, and would result in an approximate 1% increase to SCE's overall system average rate. SCE has terminated settlement negotiations and begun the litigation process for the proposed 2010 rates. A final decision is expected in the second half of 2011.


Dividend Restrictions

The CPUC regulates SCE's capital structure and limits the dividends it may pay Edison International. In SCE's most recent cost of capital proceeding, the CPUC set an authorized capital structure for SCE which included a common equity component of 48%. SCE may make distributions to Edison International as long as the common equity component of SCE's capital structure remains at or above the 48% authorized level on a 13-month weighted-average basis. At June 30, 2010, SCE's 13-month weighted-average common equity component of total capitalization was 51% resulting in the capacity to pay $461 million in additional dividends.

SCE paid dividends of $100 million to its parent, Edison International, in January 2010. Future dividend amounts and timing of distributions are dependent upon several factors, including the actual level of capital investments, operating cash flows and earnings.


Margin and Collateral Deposits

Certain derivative instruments and power procurement contracts under SCE's power and natural gas hedging activities contain collateral requirements. The table below illustrates the amount of collateral posted by SCE to its counterparties, as well as the potential collateral that would be required if SCE's credit rating fell below investment grade.

Cash Flows Provided by Operating Activities

Cash provided by operating activities decreased $959 million in the second quarter of 2010, compared to the second quarter of 2009 primarily due to the impacts of the Global Settlement, which resulted in a net tax allocation payment received in 2009 from Edison International of $875 million and an increase in deferred tax liabilities related to the settlement of affirmative claims. The 2010 change was also due to the timing of cash receipts and disbursements related to working capital items and a decrease in pre-tax income.


Cash Flows Provided (Used) by Financing Activities

Financing activities for the first six months of 2010 were as follows:

Reissued $144 million of tax-exempt pollution control bonds due in 2035. The proceeds from these bonds were used to repay commercial paper borrowings and for general corporate purposes.

Issued $500 million of first refunding mortgage bonds due in 2040. The bond proceeds were used to repay commercial paper borrowings and for general corporate purposes.

Issued $215 million of short-term debt to fund interim working capital requirements.

Repaid $250 million of senior unsecured notes.

Paid $100 million in dividends to Edison International.

Financing activities for the first six months of 2009 were as follows:

Issued $500 million of first refunding mortgage bonds due in 2039 and $250 million of first and refunding mortgage bonds due in 2014. The bond proceeds were used for general corporate purposes and to finance fuel inventories.

Repaid a net $1.9 billion of short-term debt.

Repaid $150 million of first and refunding mortgage bonds.

Table of Contents

Purchased $219 million of two issues of tax-exempt pollution control bonds and converted the issues to a variable rate structure. As discussed above, SCE reissued $144 million of these bonds during the first six months of 2010. SCE continues to hold the remaining $75 million of these bonds which are outstanding and have not been retired or cancelled.

Paid $100 million in dividends to Edison International.


Cash Flows Used by Investing Activities

Cash flows from investing activities are driven primarily by capital expenditures and funding of nuclear decommissioning trusts. Cash paid for capital expenditures was $1.8 billion and $1.4 billion for the six months ended June 30, 2010 and 2009, respectively, primarily related to transmission and distribution investments. Net purchases of nuclear decommissioning trust investments and other were $97 million and $105 million for the six months ended June 30, 2010 and 2009, respectively.

Environmental Remediation

As of June 30, 2010, SCE identified 23 sites for remediation and recorded an estimated minimum liability of $38 million. SCE expects to recover 90% of its remediation costs at certain sites. SCE expects to clean up its identified sites over a period of up to 30 years. Remediation costs in each of the next several years are expected to range from $3 million to $18 million. See "Edison International Notes to Consolidated Financial Statements Note 6. Commitments and Contingencies—Contingencies" for further discussion.


MARKET RISK EXPOSURES

For a detailed discussion of SCE's market risk exposures, including commodity price risk, credit risk and interest rate risk, see "SCE: Market Risk Exposures—Commodity Price Risk" in the year-ended 2009 MD&A.


Interest Rate Risk

At June 30, 2010, the fair market value of SCE's long-term debt (including current portion of long-term debt) was $8.1 billion, compared to a carrying value of $7.1 billion. At June 30, 2010, SCE

In compliance with a CPUC mandate, SCE held an open, competitive solicitation that produced agreements with different project developers who have agreed to construct new southern California generating resources. The contracts provide for fixed capacity payments as well as pricing for energy delivered based on a heat rate and contractual operation and maintenance prices. However, due to uncertainty regarding the availability of required emission credits, some of the generating resources may not be constructed and the contracts associated with these resources could therefore terminate, at which time SCE would no longer account for these contracts as derivatives.

The change in the fair value of derivative contracts for the six months ended June 30, 2010 was as follows:

Due to regulatory mechanisms, SCE's realized and unrealized gains and losses are recorded as regulatory assets and liabilities.

SCE recognizes realized gains and losses on derivative instruments as purchased power expense and recovers these costs, subject to reasonableness, from ratepayers. As a result, realized gains and losses are not reflected in earnings, but may temporarily affect cash flows. Due to expected future recovery from ratepayers, unrealized gains and losses are recorded as regulatory assets or liabilities and therefore are not reflected in earnings. Realized losses on economic hedging activities were primarily due to settled natural gas prices being lower than contract prices. Unrealized losses on economic hedging activities were primarily due to lower forward heat rates (spread between electricity prices and natural gas prices) related to SCE's long-term contracts from new natural gas-fired generation facilities.

Credit Risk

Credit risk exposure from counterparties for power and gas trading activities is measured as the sum of net accounts receivable (accounts receivable less accounts payable) and the current fair value of net derivative assets (derivative assets less derivative liabilities) reflected on the consolidated balance sheets. SCE enters into master agreements which typically provide for a right of setoff. Accordingly, SCE's credit risk exposure from counterparties is based on a net exposure under these arrangements. As of June 30, 2010, the amount of balance sheet exposure as described above broken down by the credit ratings of SCE's counterparties, was as follows:

SCE assigns a credit rating based on the lower of a counterparty's S&P or Moody's rating. For ease of reference, the above table uses the S&P classifications to summarize risk, but reflects the lower of the two credit ratings.

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

The credit risk exposure set forth in the above table is comprised of less than $1 million of net account receivables and $218 million representing the fair value, adjusted for counterparty credit reserves, of derivative contracts.

The CAISO comprises 87% of the total net exposure above and is mainly related to the CRRs' fair value (see "—Commodity Price Risk" for further information).

EDISON MISSION GROUP

RESULTS OF OPERATIONS

The following table is a summary of EMG's results of operations. Effective January 1, 2010, Edison International combined the competitive power generation and financial services segments into one business segment. The change resulted from termination of cross-border leases during 2009 and the continued decline of the remaining portfolio of the financial services segment. Accordingly, the financial services segment has been combined retroactively for all periods presented into one business segment. The combination of these business activities is consistent with the management structure of EMG and evaluation of performance by Edison International.


Results of Continuing Operations

This section discusses operating results for the three- and six-month periods ended June 30, 2010 and 2009. EMG's continuing operations include the fossil-fueled facilities, renewable energy and gas-fired projects, energy trading, and gas-fired projects under contract, corporate interest expense and general and administrative expenses. EMG's discontinued operations include all international operations, except the Doga project.

Table of Contents

EMG's second quarter 2010 core earnings were lower than second quarter 2009 core earnings primarily due to the following:

$160 million decreased income from Midwest Generation and Homer City due to lower realized energy revenue and higher plant maintenance costs primarily attributed to scheduled plant outages during 2010. Plant maintenance and overhaul related expenses were higher in 2010 due to the deferral of plant outages in 2009. Scheduled plant maintenance for 2010 was substantially completed in the second quarter. Lower availability in 2010 compared to the same period in 2009 was also the result of deratings caused by opacity at the Homer City facilities and transmission line tornado damage impacting the Powerton Station. In addition, EMG's results were impacted by $17 million of unrealized losses during the second quarter of 2010 compared to unrealized gains of $24 million during the same period last year.

$33 million gain in the second quarter of 2009 from the sale of an interest in a leverage lease (Midlands Cogeneration Ventures) and lower lease income from termination of cross-border leverage leases in 2009.

These decreases were partially offset by the following:

$14 million increased energy trading revenue during the second quarter of 2010 due to congestion and basis trading.

$9 million decrease in corporate expenses due primarily to lower renewable energy development expenses.

EMG's core earnings for the six months ended June 30, 2010 were lower than core earnings for the six months ended June 30, 2009 primarily due to the following:

$186 million decreased income from Midwest Generation and Homer City due to lower realized energy revenue and higher plant maintenance costs primarily attributed to scheduled plant outages during 2010. Plant maintenance and overhaul related expenses were higher in 2010 due to the deferral of plant outages in 2009. Scheduled plant maintenance for 2010 was substantially completed in the first half of the year. Lower availability in 2010 compared to the same period in 2009 was also the result of deratings caused by opacity at the Homer City facilities and transmission line tornado damage impacting the Powerton Station. In addition, EMG's results were impacted by $17 million of unrealized losses during the six months ended June 30, 2010 compared to unrealized gains of $39 million during the same period last year.

$33 million gain in the second quarter of 2009 from the sale of an interest in a leverage lease (Midlands Cogeneration Ventures) and lower lease income from termination of cross-border leverage leases in 2009.

These decreases were partially offset by the following:

$51 million increased energy trading revenue due to congestion and basis trading.

$9 million decrease in corporate expenses due primarily to lower renewable energy development expenses.

Consolidated non-core items for EMG included:

An earnings benefit of approximately $58 million recorded in the second quarter of 2010 resulting from acceptance by the California Franchise Tax Board of the tax positions finalized with the IRS in 2009 as part of the Global Settlement for tax years 1986 through 2002 and revision to interest recorded on the federal Global Settlement.

AOI is equal to operating income under GAAP, plus equity in earnings 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 EMG.

Included in fuel costs were $1 million and $14 million during the second quarters of 2010 and 2009, respectively, and $5 million and $33 million during the six months ended June 30, 2010 and 2009, 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 NO X emission allowances to Midwest Generation were $0.4 million and $1 million during the six months ended June 30, 2010 and 2009, respectively. Transfers of SO 2 emission allowances from Midwest Generation were $5 million during the first six months of 2010. For more information regarding the price of emission allowances, see "EMG: Market Risk Exposures—Commodity Price Risk—Emission Allowances Price Risk."

AOI from the Midwest Generation plants decreased $113 million and $140 million for the second quarter and six months ended June 30, 2010, respectively, compared to the corresponding periods of 2009. The 2010 decreases in AOI were primarily attributable to an increase in plant operations costs related to scheduled plant outages, unrealized losses related to hedge contracts and a decline in realized gross margin. Plant maintenance and overhaul related expenses were higher in 2010 due to the deferral of plant outages in 2009. Scheduled plant maintenance for 2010 was substantially completed in the second quarter. The decline in realized gross margin during the second quarter was driven by lower generation, partially offset by higher capacity revenues. The year-to-date decline in realized gross margin was driven by lower average realized energy prices, partially offset by higher capacity revenues.

Included in operating revenues were unrealized gains (losses) of $(3) million and $5 million for the second quarters of 2010 and 2009, respectively, and $4 million and $20 million for the six months ended June 30, 2010 and 2009, respectively. Unrealized gains (losses) in 2010 were due to both the

Table of Contents


ineffective portion of forward and futures contracts which are derivatives that qualify as cash flow hedges, and hedge contracts which are not accounted for as cash flow hedges (referred to as economic hedges). Unrealized gains in 2009 were primarily due to economic hedge contracts that are accounted for on a mark-to-market basis.

Included in fuel expenses were unrealized gains (losses) of $(2) million and $14 million for the second quarters of 2010 and 2009, respectively, and $(7) million and $14 million for the six months ended June 30, 2010 and 2009, respectively. Unrealized gains (losses) were due to oil futures contracts, which were accounted for as economic hedges. The contracts hedge a portion of a fuel adjustment mechanism of a rail transportation contract.

Included in fuel costs were $1 million during each of the second quarters of 2010 and 2009, and $5 million and $8 million during the six months ended June 30, 2010 and 2009, 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 SO 2 emission allowances to Homer City were $5 million during the six months ended June 30, 2010. Transfers of NO x emission allowances from Homer City were $0.4 million and $1 million during the six months ended June 30, 2010 and 2009, respectively. For more information regarding the price of emission allowances, see "EMG: Market Risk Exposures—Commodity Price Risk—Emission Allowances Price Risk."

AOI from the Homer City facilities decreased $47 million and $46 million for the second quarter and six months ended June 30, 2010, respectively, compared to the corresponding periods of 2009. The 2010 decreases in AOI were primarily attributable to an increase in plant operations costs related to scheduled plant outages, higher unrealized losses related to hedge contracts and a decline in realized gross margin. Plant maintenance and overhaul related expenses were higher in 2010 due to the deferral of plant outages in 2009. Scheduled plant maintenance for 2010 was substantially completed in the

second quarter. The decline in realized gross margin was driven by lower generation and higher coal costs, partially offset by higher capacity revenues.

Included in operating revenues were unrealized gains (losses) from hedge activities of $(12) million and $5 million for the second quarters of 2010 and 2009, respectively, and $(14) million and $5 million for the six months ended June 30, 2010 and 2009, respectively. Unrealized gains (losses) in 2010 and 2009 were primarily attributable to the ineffective portion of forward and futures contracts which are derivatives that qualify as cash flow hedges. The ineffective portion of hedge contracts at Homer City was attributable to changes in the difference between energy prices at the 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 facilities is delivered into the transmission system). For more information regarding forward market prices and unrealized gains (losses), see "EMG: Market Risk Exposures—Commodity Price Risk" and "EMG: Results of Operations—Derivative Instruments."


Non-GAAP Disclosures—Fossil-Fueled Facilities

Adjusted Operating Income

AOI is equal to operating income (loss) plus other income (expense) for the fossil-fueled facilities. AOI is a non-GAAP performance measure and may not be comparable to those of other companies. Management believes that inclusion of other income (expense) is meaningful for investors as the components of other income (expense) are integral to the operating results of the fossil-fueled facilities.


Seasonal Disclosure—Fossil-Fueled Facilities

Due to fluctuations in electric demand resulting from warmer weather during the summer months and cold weather during the winter months, electric revenues from the fossil-fueled facilities 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, AOI from the fossil-fueled facilities 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 "EMG: Market Risk Exposures—Commodity Price Risk—Energy Price Risk Affecting Sales from the Fossil-Fueled Facilities."

AOI is equal to operating income (loss) plus equity in earnings (losses) of unconsolidated affiliates, 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. The following table reconciles AOI as shown above to operating income (loss) under GAAP:

Includes renewable energy projects that are unconsolidated at EMG. Generation excluding unconsolidated projects was 821 GWh and 1,512 GWh for the three months and six months ended June 30, 2010, respectively.

AOI from renewable energy projects increased $8 million and decreased $8 million for the second quarter and six months ended June 30, 2010, respectively, compared to the corresponding periods of 2009. The second quarter increase in AOI was primarily attributable to higher generation resulting from an increase in projects in operations. The year-to-date decrease in AOI results from higher depreciation and operations costs related to additional projects in operations, offset by the impact of the deconsolidation of two renewable projects in 2010. AOI in the second quarter and six months ended June 30, 2009 included $5 million and $16 million, respectively, of liquidated damages from availability guarantees provided by a wind turbine supplier, which compensated EMG for lower generation (none recorded in 2010). The second quarter ended June 30, 2010 did not include liquidated damages for equipment warranty related items given completion of the blade remediation

program. During the second quarter of 2010, EMG received $92 million in U.S. Treasury grants, which was recorded as deferred revenue and is recognized as revenue over the life of the project.


Energy Trading

EMG seeks to generate profit by utilizing its subsidiary, EMMT, to engage in trading activities in those markets in which it is active as a result of its management of the merchant power plants of Midwest Generation and Homer City. EMMT trades power, fuel, coal, and transmission congestion primarily in the eastern U.S. power grid using products available over the counter, through exchanges, and from ISOs.

AOI from energy trading activities increased $14 million and $51 million for the second quarter and six months ended June 30, 2010, respectively, compared to the corresponding periods of 2009. The 2010 increases in AOI from energy trading activities were attributable to increased revenue in congestion and basis trading.


Adjusted Operating Income from Leveraged Lease Activities

AOI from leveraged lease income decreased by $10 million for the six months ended June 30, 2010, compared to the corresponding period of 2009 due to the termination of the cross-border leases and the sale of a lease investment during the first half of 2009.


Adjusted Operating Income from Lease Termination and Other

AOI from lease termination and other included losses of $889 million for the six months ended June 30, 2009 due to the termination of the cross-border leases. (See "Edison International Notes to Consolidated Financial Statements—Note 4. Income Taxes" of the 2009 Form 10-K, for further information.


Adjusted Operating Income from Unconsolidated Affiliates

Doga

AOI from the Doga project decreased $8 million and increased $7 million for the second quarter and six months ended June 30, 2010, respectively, compared to the corresponding periods of 2009 due to the timing of distributions. AOI is recognized when cash is distributed from the project since the Doga project is accounted for on the cost method.


March Point

AOI from the March Point project increased $14 million for the six months ended June 30, 2010, compared to the corresponding period of 2009. The 2010 increase was primarily due to an $18 million equity distribution received from the project in February 2010. EMG subsequently sold its ownership interest in the March Point project to its partner at book value.


Seasonal Disclosure

EMG'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.

The 2010 decrease in interest expense was primarily due to higher capitalized interest and lower debt balances under EME's and Midwest Generation's credit facilities. Capitalized interest for projects under construction increased $8 million and $13 million for the second quarter and six months ended June 30, 2010, respectively, compared to the corresponding periods of 2009. The year-to-date variance was also due to the repayment of debt at EME Funding related to the Big 4 projects.


Income Taxes

EMG's income taxes from continuing operations during the second quarter of 2010 included a $58 million income tax benefit resulting from acceptance by the California Franchise Tax of the tax positions finalized with the IRS as part of the Global Settlement for tax years 1986 through 2002. In addition, the income taxes for the six months ended June 30, 2010 and 2009, included tax benefits of production and housing tax credits of $34 million during each period. During the second quarter of 2009, an income tax benefit was recorded on a pre-tax loss on termination of leverage leases at Edison Capital and impact of the federal Global Settlement finalized with the IRS.


Results of Discontinued Operations

Income from discontinued operations, net of tax, increased $8 million and $12 million for the second quarter and six months ended June 30, 2010, respectively, compared to the corresponding periods of 2009. The 2010 increase was due to lower foreign exchange rates. The year-to-date increase was due to a reduction in EMG's estimated liability due primarily to expiration of a contract indemnity during the first quarter of 2010. EMG increased its estimated liability for a tax indemnity by $6 million in the second quarter and six months ended June 30, 2009.

LIQUIDITY AND CAPITAL RESOURCES

Available Liquidity

At June 30, 2010, EMG and its subsidiaries had consolidated cash and cash equivalents of $746 million and a total of $961 million of capacity under its credit facilities. EMG's consolidated debt at June 30, 2010 was $4.1 billion, of which $107 million was current. In addition, EMG's subsidiaries had $3.0 billion of long-term lease obligations related to their sale-leaseback transactions that are due over periods ranging up to 25 years.

As a result of credit ratings actions in 2010, described under "—Credit Ratings," the margins applicable to Midwest Generation's $500 million working capital facility increased 27.5 basis points. Borrowings made under this credit facility currently bear interest at LIBOR plus 1.15%, unless average utilized commitments during a period exceed $250 million, in which case the margin increases to 1.275%.

For the remainder of 2010, EMG anticipates capital expenditures of $635 million (excluding a $289 million disputed amount under a turbine supply agreement) to be funded with a combination of project-level financing, U.S. Treasury grants, cash on hand, and cash flow from operations. EMG secured a $206 million vendor financing, of which $200 million was available at June 30, 2010, and a $160 million project financing, of which $70 million was available at June 30, 2010. EMG intends to file for U.S. Treasury grants for its renewable energy projects in construction.

EMG may from time to time seek to retire or purchase its outstanding debt through cash purchases and/or exchange offers, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, EMG's liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Environmental expenditures include primarily expenditures related to SNCR equipment and $156 million for expenditures during the remainder of 2010 to 2012 to retrofit initial units using dry scrubbing with sodium-based sorbents to comply with CPS requirements for SO 2 emissions. Midwest Generation could elect to shut down units instead of installing controls to be in compliance with the CPS, 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. For additional discussion, see "Edison International Overview—Environmental Developments" and refer to "Environmental Regulation of Edison International and Subsidiaries" in the 2009 Form 10-K.

Includes projects under construction where project financing has been secured. The available balance under secured financing arrangements was $270 million as of June 30, 2010. For further discussion, see "Edison International Notes to Consolidated Financial Statements—Note 3. Liabilities and Lines of Credit," and refer to "EMG: Liquidity and Capital Resources Project-Level Financing" in the year-ended 2009 MD&A.

Turbine commitment figures exclude $289 million which is subject to dispute under provisions in one of the turbine supply agreements. In March 2010, EME filed a breach of contract complaint against this turbine supplier. For additional discussion, see "Legal Proceedings" in Part II of this quarterly report.


Estimated Expenditures for Existing Projects

Plant capital expenditures relate to non-environmental projects such as upgrades to boiler and turbine controls, replacement of major boiler components, mill steam inerting projects, generator stator rewinds, 4Kv switchgear and main power transformer replacement.

Environmental expenditures at Homer City relate to emission monitoring and control projects. Midwest Generation is subject to various commitments with respect to environmental compliance. Expenditures, in addition to those included on the preceding table, are anticipated and could be material; however,

the amounts and timing have not been determined. For more information on the current status of environmental improvements in Illinois, see "Edison International Overview—Environmental Developments." For further discussion of environmental regulations, refer to "Environmental Regulation of Edison International and Subsidiaries" in the 2009 Form 10-K.


Estimated Expenditures for Future Projects

EMG has wind turbines in storage and on order for wind projects under construction and to be used for future wind projects (turbine commitments are reflected separately in the preceding capital expenditure table). Amounts exclude balance of project costs for 102 MW available for new projects, which EMG estimates to be an additional $75 million to $120 million based on typical project costs. The pace of additional growth in EMG's renewables program will be subject to the availability of projects that meet EMG's requirements and the capital needed for development, which will be affected by the extent of internally generated cash flow and future decisions about capital expenditures for environmental compliance by its coal fleet. Consequently, pending substantial progress on or financing of the environmental retrofits, growth of the renewables programs may depend upon the availability of outside project-level debt and equity financing. Successful completion of the development of a wind project depends upon obtaining permits and agreements necessary to support an investment and may take a number of years due to factors that include local permit requirements, willingness of local utilities to purchase renewable power at sufficient prices to earn an appropriate rate of return, and availability and prices of equipment.

Cash Flows Used by Operating Activities

Cash used by operating activities from continuing operations decreased $1 billion in the first six months of 2010, compared to the first six months of 2009. The 2009 change was primarily due to the impacts of the Global Settlement which resulted in remittances of net tax allocation payments to Edison International of $1.1 billion by Edison Capital related to the termination of Edison Capital's interests in cross-border leases (see "Item 8. Edison International Notes to Consolidated Financial Statements—Note 4. Income Taxes" of the 2009 Form 10-K for further discussion). In April 2010, Edison Capital funded a $253 million deposit to the IRS related to the Global Settlement. The 2010 change was also due to a decrease in cash collateral deposits for risk management and energy trading compared to 2009, $92 million received related to U.S. Treasury grants, and changes in the timing of cash receipts and disbursements related to working capital items.

Table of Contents


Cash Flows Provided (Used) by Financing Activities

Cash provided (used) by financing activities from continuing operations decreased $199 million in the first six months of 2010, compared to the first six months of 2009. The 2010 decrease was primarily attributable to lower levels of renewable energy project financing. For further project financing details, see "Edison International Notes to Consolidated Financial Statements—Note 3. Liabilities and Lines of Credit." In addition, in January 2010, Edison Capital redeemed in full its medium-term loans.


Cash Flows Provided (Used) by Investing Activities

Cash provided (used) by investing activities from continuing operations decreased $1.5 billion in the first six months of 2010, compared to the first six months of 2009. The 2010 decrease was primarily due to $1.385 billion of net proceeds from termination of the cross-border leases at Edison Capital in 2009. The change was also due to higher expenditures for construction of renewable energy projects compared to 2009.


Credit Ratings

Overview

On June 29, 2010, Moody's lowered the credit ratings of EME to B3 from B2 and Midwest Generation to Ba2 from Ba1. 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.

EMG does not have any "rating triggers" contained in subsidiary financings that would result in it being required 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. For discussions of contingent features related to energy contracts, see "—Margin, Collateral Deposits and Other Credit Support for Energy Contracts."


Credit Rating of EMMT

For a discussion of the effect of EMMT's credit rating on EMG's ability to sell forward the output of the Homer City facilities through EMMT, refer to "EMG: Liquidity and Capital Resources—Credit Ratings—Credit Rating of EMMT" in the year-ended 2009 MD&A.


Margin, Collateral Deposits and Other Credit Support for Energy Contracts

Future cash collateral requirements may be higher than the margin and collateral requirements were at June 30, 2010, if wholesale energy prices change or if EMMT enters into additional transactions. EMG estimates that margin and collateral requirements for energy and congestion contracts outstanding as of June 30, 2010 could increase by approximately $184 million over the remaining life of the contracts using a 95% confidence level. This increase may not be offset by similar changes in the cash flows of the underlying hedged items in the same periods. Certain EMMT hedge contracts do not require margin, but contain provisions that require EMG or Midwest Generation to comply with the terms and

83


Table of Contents


conditions of their credit facilities. The credit facilities contain financial covenants which are described further in "—Debt Covenants and Dividend Restrictions."

Hedge contracts include provisions relating to a change in control or material adverse effect resulting from amendments or modifications to the related credit facility. EMMT 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. The aggregate fair value of all derivative instruments with credit-risk-related contingent features is in an asset position at June 30, 2010 and, accordingly, the contingent features described above do not currently have a liquidity exposure. Future increases in power prices could expose EME or Midwest Generation to termination payments or additional collateral postings under the contingent features described above.

Midwest Generation has cash on hand and a credit facility to support margin requirements specifically related to contracts entered into by EMMT related to the Midwest Generation plants. In addition, EMG has cash on hand and a credit facility to provide credit support to subsidiaries. For discussion on available borrowing capacity under Midwest Generation and EME credit facilities, see "—Available Liquidity."

Energy and capacity from the fossil-fueled facilities are sold under terms, including price, duration and quantity, arranged by EMMT with customers through a combination of bilateral agreements (resulting from negotiations or from auctions), forward energy sales and spot market sales. Power is sold into PJM at spot prices based upon locational marginal pricing. Hedging transactions related to generation are generally entered into at the Northern Illinois Hub or the AEP/Dayton Hub, both in PJM, for the Midwest Generation plants and generally at the PJM West Hub for the Homer City facilities. These trading hubs have been the most liquid locations for hedging purposes.

The following table depicts the average historical market prices for energy per megawatt-hour at the locations indicated for the first six months of 2010 and 2009:

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

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

Forward market prices at the Northern Illinois Hub and PJM West Hub fluctuate as a result of a number of factors, including natural gas prices, transmission congestion, changes in market rules, electricity demand (which in turn is affected by weather, economic growth, and other factors), plant outages in the region, and the amount of existing and planned power plant capacity. The actual spot prices for electricity delivered by the fossil-fueled facilities into these markets may vary materially from the forward market prices set forth in the preceding table.

EMMT engages in hedging activities for the fossil-fueled facilities to hedge the risk of future change in the price of electricity. The following table summarizes the hedge positions (including load-serving transactions and forward contracts accounted for on the accrual basis) as of June 30, 2010 for electricity expected to be generated during the remainder of 2010 and in 2011 and 2012:

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

Includes hedging transactions primarily at the PJM West Hub and to a lesser extent at other trading locations. Years 2010, 2011 and 2012 include hedging activities entered into by EMMT for the Homer City facilities that are not designated under the intercompany agreements with Homer City due to limitations under the sale leaseback transaction documents.

Capacity not sold arises from: (i) capacity retained to meet forced outages under the RPM auction guidelines, and (ii) capacity that PJM does not purchase at the clearing price resulting from the RPM auction.

2
Other capacity sales and purchases, net includes contracts executed in advance of the RPM base residual auction to hedge the price risk related to such auction, participation in RPM incremental auctions and other capacity transactions entered into to manage capacity risks.

3
Includes the impact of a 100 MW capacity swap transactions executed prior to the base residual auction at $135 MW-day.

The RPM auction capacity prices for the delivery period of June 1, 2013 to May 31, 2014 varied between different areas of PJM. In the western portion of PJM, affecting Midwest Generation, the price of $27.73 per MW-day was substantially lower than other areas' capacity prices. The impact of lower capacity prices for this period compared to previous years will have an adverse effect on Midwest Generation's revenues unless such lower capacity prices are offset by an unavailability of competing resources and increased energy prices, which is uncertain.


Basis Risk

During the six months ended June 30, 2010, transmission congestion in PJM has resulted in prices at the individual busbars of the Midwest Generation plants being lower than those at the AEP/Dayton Hub and Northern Illinois Hub by an average of 11% and 1%, respectively, compared to 17% and less

than 1%, respectively, during the six months ended June 30, 2009. During the six months ended June 30, 2010 and 2009, transmission congestion in PJM has resulted in prices at the Homer City busbar being lower than those at the PJM West Hub by an average of 13% and 8%, respectively.


Coal and Transportation Price Risk

The Midwest Generation plants and Homer City facilities purchase coal primarily from the Southern PRB of Wyoming and from mines located near the facilities in Pennsylvania, respectively. Coal purchases are made under a variety of supply agreements. The following table summarizes the amount of coal under contract at June 30, 2010 for the remainder of 2010 and the following three years:

The amount of coal under contract in tons is calculated based on contracted tons and applying an 8,800 Btu equivalent for the Midwest Generation plants and 13,000 Btu equivalent for the Homer City facilities.

2
In July 2010, Midwest Generation entered into additional contracts for the purchase of 3.9 million tons of coal for 2011.

EMG is subject to price risk for purchases of coal that are not under contract. Prices of Northern Appalachian (NAPP) coal, which are related to the price of coal purchased for the Homer City facilities, increased during 2010 from 2009 year-end prices. The market price of NAPP coal (with 13,000 Btu per pound heat content and <3.0 pounds of SO 2 per MMBtu sulfur content) increased to a price of $62.75 per ton at July 2, 2010, compared to a price of $52.50 per ton at December 31, 2009, as reported by the Energy Information Administration.

Prices of PRB coal (with 8,800 Btu per pound heat content and 0.8 pounds of SO 2 per MMBtu sulfur content) purchased for the Midwest Generation plants increased during 2010 from 2009 year-end prices. The market price of PRB coal increased to a price of $13.05 per ton at July 2, 2010, compared to a price of $9.25 per ton at December 31, 2009, as reported by the Energy Information Administration.

EMG has contracts for the transport of coal to its facilities. The primary contract is with Union Pacific Railroad (and various short-haul carriers), which extends through 2011. EMG is exposed to price risk related to transportation rates after the expiration of its existing transportation contracts. Current market transportation rates for PRB coal are higher than the existing rates under contract. Transportation costs are approximately half of the delivered cost of PRB coal to the Midwest Generation plants.


Emission Allowances Price Risk

EMG purchases (or sells) emission allowances for the fossil-fueled facilities based on the amounts required for actual generation in excess of (or less than) the amounts allocated to these facilities under applicable programs. In the event that actual emission allowances required are greater than allowances held, EMG is subject to price risk for purchases of emission allowances. The market price for emission allowances may vary significantly. The average purchase price of SO 2 allowances decreased to $50 per

89


Table of Contents


ton during the six months ended June 30, 2010 from $65 per ton in 2009. The average purchase price of annual NO x allowances decreased to $974 per ton during the six months ended June 30, 2010 from $1,431 per ton in 2009. Based on broker's quotes and information from public sources, the spot price for SO 2 allowances and annual NO x allowances was $15 per ton and $465 per ton, respectively, at June 30, 2010.

For a discussion of environmental regulations related to emissions, refer to "Environmental Regulation of Edison International and Subsidiaries" in the 2009 Form 10-K.

Credit Risk

The credit risk exposure from counterparties of merchant energy hedging and trading activities is measured as the sum of net receivables (accounts receivable less accounts payable) and the current fair value of net derivative assets. EMG's subsidiaries enter into master agreements and other arrangements in conducting such activities which typically provide for a right of setoff in the event of bankruptcy or default by the counterparty. At June 30, 2010, the balance sheet exposure as described above, broken down by the credit ratings of EMG's counterparties, was as follows:

EMG assigns a credit rating based on the lower of a counterparty's S&P or Moody's rating. For ease of reference, the above table uses the S&P classifications to summarize risk, but reflects the lower of the two credit ratings.

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

The credit risk exposure set forth in the above table is comprised of $139 million of net accounts receivable and payables and $207 million representing the fair value of derivative contracts. The exposure is based on master netting agreements with the related counterparties. Due to developments in the financial markets, credit ratings may not be reflective of the actual related credit risks. In addition to the amounts set forth in the above table, EMG's subsidiaries have posted a $108 million cash margin in the aggregate with PJM, New York Independent System Operator (NYISO), Midwest Independent Transmission System Operator (MISO), clearing brokers and other counterparties to support hedging and trading activities. The margin posted to support these activities also exposes EMG to credit risk of the related entities.

The fossil-fueled facilities sell electric power generally into the PJM market by participating in PJM's capacity and energy markets or transact in capacity and energy on a bilateral basis. Sales into PJM accounted for approximately 67% of EMG's consolidated operating revenues for the six months ended June 30, 2010. PJM, a regional transmission organization (RTO) with over 300 member companies, maintains its own credit risk policies and does not extend unsecured credit to non-investment grade

companies. Losses resulting from a PJM member default are shared by all other members using a predetermined formula. At June 30, 2010, EMG's account receivable due from PJM was $66 million.

The terms of EMG's wind turbine supply agreements contain significant obligations of the suppliers in the form of manufacturing and delivery of turbines, and payments for delays in delivery and for failure to meet performance obligations and warranty agreements. EMG's reliance on these contractual provisions is subject to credit risks. Generally, these are unsecured obligations of the turbine manufacturer. A material adverse development with respect to EMG's turbine suppliers may have a material impact on EMG's wind projects and development efforts.

Interest Rate Risk

Interest rate changes can affect earnings and the cost of capital for capital improvements or new investments in power projects. EMG mitigates the risk of interest rate fluctuations by arranging for fixed rate financing or variable rate financing with interest rate swaps, interest rate options or other hedging mechanisms for a number of its project financings. For details, see "Edison International Notes to Consolidated Financial Statements—Note 3. Liabilities and Lines of Credit." The fair market value of fixed interest rate obligations are subject to interest rate risk. The fair market value of EMG's consolidated short-term debt and long-term obligations (including current portion) was $2.8 billion at June 30, 2010, compared to the carrying value of $4.1 billion.

Mitsubishi Lawsuit

EME and Mitsubishi Power Systems Americas, Inc. are parties to a wind turbine generator supply agreement executed in March 2007 with respect to the purchase of 166 wind turbines and related services and warranties. Mitsubishi has delivered 83 wind turbines under the agreement. The remaining wind turbines, among other items, are under dispute.

EME filed a complaint on March 19, 2010, and an amended complaint on April 1, 2010, in the Superior Court of the State of California against Mitsubishi Power Systems Americas, Inc. and Mitsubishi Heavy Industries, Ltd with respect to a wind turbine generator supply agreement for the purchase of wind turbines and related services and warranties. EME's complaint alleges, among other things: (a) that the Mitsubishi entities fraudulently induced EME to enter into the supply agreement by misrepresenting the facts and circumstances surrounding Mitsubishi's rights to certain technology incorporated into the turbines; (b) that the Mitsubishi entities breached the implied covenant of good faith and fair dealing; (c) that the Mitsubishi entities breached their warranty obligations; (d) that the Mitsubishi entities repudiated the supply agreement when they failed to provide EME with adequate assurances of performance; and (e) that certain price escalation provisions in the supply agreement do not reflect the intent of the contracting parties.

The complaint asks the Court for an order finding the supply agreement void and unenforceable or, in the alternative, for an order reforming its price escalation provisions to conform to the contracting parties' intent. The complaint also requests an order of specific performance requiring the Mitsubishi entities to honor their warranties with respect to equipment already purchased, an award of monetary damages (including exemplary and punitive damages), and an accounting of all amounts due under the supply agreement, including reimbursement to EME of amounts previously paid for units it can no longer use and is excused from accepting, together with prejudgment interest, and such other relief as the Court may deem just and proper. In June 2010, EME filed a motion to amend its complaint to include, among other things, additional support for its claims.

The failure of the Mitsubishi entities to perform certain previously contracted services pertaining to the Taloga project, including delivery and commissioning of turbines still in storage, could delay the development of the Taloga project. If the Taloga project does not achieve commercial operation by March 31, 2011, subject to extension under certain circumstances, Taloga's offtaker could seek to terminate or renegotiate its power purchase agreement.
