NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Summary of Significant Accounting Policies

Edison International has two business segments for financial reporting purposes: an electric utility segment ("SCE") and a competitive power generation segment ("EMG"). SCE is an investor-owned public utility primarily engaged in the business of supplying electricity to an approximately 50,000 square mile area of southern California. EMG is the holding company for its principal wholly owned subsidiary, EME. EME is a holding company with subsidiaries and affiliates engaged in the business of developing, acquiring, owning or leasing, operating and selling energy and capacity from independent power production facilities. EME also engages in hedging and energy trading activities in competitive power markets through its Edison Mission Marketing & Trading, Inc. ("EMMT") subsidiary.

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 2011 Form 10-K. The same accounting policies are followed for interim reporting purposes, with the exception of accounting principles adopted as of January 1, 2012, discussed below in "—New Accounting Guidance." This quarterly report should be read in conjunction with the financial statements and notes included in the 2011 Form 10-K.

In the opinion of management, all adjustments, consisting of 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 nine -month periods ended September 30, 2012 are not necessarily indicative of the operating results for the full year.

The December 31, 2011 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.

Interim Financial Statements

On September 21, 2012 , EME Homer City Generation L.P. ("Homer City") and Homer City Generation L.P., an affiliate of General Electric Capital Corporation ("GECC"), entered into a Master Transaction Agreement ("Homer City MTA") for the divestiture by Homer City of substantially all of its remaining assets and certain specified liabilities.

Beginning in the third quarter of 2012, Homer City met the definition of a discontinued operation and was classified separately in Edison International's consolidated financial statements. Previously issued financial statements have been restated to reflect discontinued operations reported subsequent to the original issuance date. For further information, see Note 18—Discontinued Operations. Except as indicated, amounts in the notes to the consolidated financial statements relate to continuing operations of Edison International.

Cash Equivalents

Cash equivalents included investments in money market funds totaling $933 million and $ 1.3 billion at September 30, 2012 and December 31, 2011 , respectively. Generally, the carrying value of cash equivalents equals the fair value, as these investments have original maturities of three months or less.

Edison International temporarily invests the ending daily cash balance in its primary disbursement accounts until required for check clearing. Edison International reclassified $234 million and $220 million of checks issued, but not yet paid by the financial institution, from cash to accounts payable at September 30, 2012 and December 31, 2011 , respectively.

Restricted Cash and Cash Equivalents, and Restricted Deposits

Restricted cash and cash equivalents at September 30, 2012 and December 31, 2011 included $97 million received from a wind project financing that was held in escrow at those dates. At September 30, 2012 , restricted deposits included $48 million to support outstanding letters of credit issued under EME's letter of credit facilities.

Inventory

Inventory is stated at the lower of cost or market, cost being determined by the weighted-average cost method for fuel, and the average cost method for materials and supplies. Inventory consisted of the following:



(in millions)	September 30, 2012		December 31, 2011
Coal, gas, fuel oil and other raw materials	$	138	$	143
Spare parts, materials and supplies	370		376
Total inventory	$	508	$	519

Revenue Recognition

Electric Utility Revenue

Operating revenue is recognized when electricity is delivered and includes amounts for services rendered but unbilled at the end of each reporting period. During the first nine months of 2012, pending the outcome of the 2012 GRC, SCE recognized GRC-related revenue based on the 2011 authorized revenue requirement included in customer rates. A GRC memorandum account has been established for SCE, which will make the 2012 revenue requirement ultimately adopted by the CPUC effective as of January 1, 2012.

Earnings Per Share

Edison International computes earnings per share ("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. EPS attributable to Edison International common shareholders was computed as follows:



	Three months ended September 30,				Nine months ended September 30,
(in millions)	2012		2011		2012		2011
Basic earnings per share – continuing operations:
Income from continuing operations attributable to common shareholders, net of tax	$	266	$	411	$	486	$	805
Participating securities dividends	—		—		—		—
Income from continuing operations available to common shareholders	$	266	$	411	$	486	$	805
Weighted average common shares outstanding	326		326		326		326
Basic earnings per share – continuing operations	$	0.81	$	1.26	$	1.49	$	2.47
Diluted earnings per share – continuing operations:
Income from continuing operations available to common shareholders	$	266	$	411	$	486	$	805
Income impact of assumed conversions	—		2		1		3
Income from continuing operations available to common shareholders and assumed conversions	$	266	$	413	$	487	$	808
Weighted average common shares outstanding	326		326		326		326
Incremental shares from assumed conversions	3		3		2		3
Adjusted weighted average shares – diluted	329		329		328		329
Diluted earnings per share – continuing operations	$	0.81	$	1.25	$	1.48	$	2.46

Stock-based compensation awards to purchase 3,238,581 and 5,943,378 shares of common stock for the three months ended September 30, 2012 and 2011 , respectively, and 4,819,683 and 8,970,290 shares of common stock for the nine months ended September 30, 2012 and 2011 , respectively, were outstanding, but were not included in the computation of diluted earnings per share because the exercise price of the awards was greater than the average market price of the common shares and therefore, the effect would have been antidilutive.

New Accounting Guidance

Accounting Guidance Adopted in 2012

Fair Value Measurement

In May 2011, the Financial Accounting Standards Board ("FASB") issued an accounting standards update modifying the fair value measurement and disclosure guidance. This guidance prohibits grouping of financial instruments for purposes of fair value measurement and requires the value be based on the individual security. This amendment also results in new disclosures primarily related to Level 3 measurements including quantitative disclosure about unobservable inputs and assumptions, a description of the valuation processes and a narrative description of the sensitivity of the fair value to changes in unobservable inputs. Edison International adopted this guidance effective January 1, 2012. For further information, see Note 4.

Presentation of Comprehensive Income

In June 2011 and December 2011, the FASB issued accounting standards updates on the presentation of comprehensive income. An entity can elect to present items of net income and other comprehensive income in one continuous statement, referred to as the statement of comprehensive income, or in two separate but consecutive statements. Edison International adopted this guidance January 1, 2012, and elected to present two separate but consecutive statements. The adoption of these accounting standards updates did not change the items that constitute net income and other comprehensive income.

Accounting Guidance Not Yet Adopted

Offsetting Assets and Liabilities

In December 2011, the FASB issued an accounting standards update modifying the disclosure requirements about the nature of an entity's rights of offsetting assets and liabilities in the statement of financial position under master netting agreements and related arrangements associated with financial and derivative instruments. The guidance requires increased disclosure of the gross and net recognized assets and liabilities, collateral positions and narrative descriptions of setoff rights. Edison International will adopt this guidance effective January 1, 2013.

¹	During the nine months ended September 30, 2011 , EMG purchased the remaining interests in Pinnacle Wind Force, LLC, and Broken Bow I, LLC and all assets of the Crofton Bluffs project. All three projects are now 100% owned by EMG. The purchases of the noncontrolling interests were accounted for as equity transactions between controlling and noncontrolling interest holders.

Note 3. Variable Interest Entities

Categories of Variable Interest Entities

Projects or Entities that are Consolidated

At September 30, 2012 and December 31, 2011 , 16 and 13 wind projects were consolidated with a total generating capacity of 861 MW and 570 MW, respectively, that have noncontrolling interests held by others. The increase from the projects consolidated after December 31, 2011 was due to the Capistrano Wind equity capital transaction discussed below. In determining that Edison International's subsidiary, EME, was the primary beneficiary of the projects that are consolidated, key factors considered were EME's ability to direct commercial and operating activities and EME's obligation to absorb losses of the variable interest entities.

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



(in millions)	September 30, 2012		December 31, 2011
Current assets	$	71	$	36
Net property, plant and equipment	1,090		675
Other long-term assets	73		5
Total assets	$	1,234	$	716
Current liabilities	$	40	$	28
Long-term debt net of current portion	172		57
Deferred revenues	172		69
Long-term derivative liabilities	23		—
Other long-term liabilities	38		22
Total liabilities	$	445	$	176
Noncontrolling interests	$	238	$	2

Assets serving as collateral for the debt obligations had a carrying value of $467 million and $136 million at September 30, 2012 and December 31, 2011 , respectively, and primarily consist of property, plant and equipment.

Capistrano Wind Equity Capital

On February 13, 2012, Edison Mission Wind Inc. ("Edison Mission Wind") sold its indirect equity interests in the Cedro Hill wind project ( 150 MW in Texas), the Mountain Wind Power I project ( 61 MW in Wyoming) and the Mountain Wind Power II project ( 80 MW in Wyoming) to a new venture, Capistrano Wind Partners. Outside investors provided $238 million of the funding. Capistrano Wind Partners also agreed to acquire the Broken Bow I wind project ( 80 MW in Nebraska) and the Crofton Bluffs wind project ( 40 MW in Nebraska) for consideration expected to include $140 million from the same outside investors upon the satisfaction of specified conditions, including commencement of commercial operation and conversion of project debt financing to term loans. In March 2012, EME received a distribution of the proceeds from outside investors, which was used for general corporate purposes. Through their ownership of Capistrano Wind Holdings, an indirect subsidiary of EME, Edison Mission Wind, and EME's parent company, Mission Energy Holding Company ("MEHC"), own 100% of the Class A equity interests in Capistrano Wind Partners, and the Class B preferred equity interests are held by outside investors. Under the terms of the formation documents, preferred equity interests receive 100% of the cash available for distribution, up to a scheduled amount to target a certain return and thereafter cash distributions are shared. Cash available for distribution includes 90% of the tax benefits realized by MEHC and contributed to Capistrano Wind Partners.

Edison Mission Wind retains indirect beneficial ownership of the common equity in the projects, net of a $4 million preferred investment made by MEHC, a note receivable of $107 million from the sale of the project companies, and retains responsibilities for managing the operations of Capistrano Wind Holdings and its projects, and accordingly, EME will continue to consolidate these projects. The $238 million contributed by the third-party interests is reflected in "Other noncontrolling interests" on Edison International's consolidated balance sheets at September 30, 2012 . This transaction was accounted for as a transfer among entities under common control and, therefore, resulted in no change in the book basis of the transferred assets. However, the transaction triggered a taxable gain and new tax basis in the assets with a corresponding adjustment to deferred taxes and a reduction to equity of $21 million .

Variable Interest in VIEs that are not Consolidated

Power Purchase Contracts

SCE has 17 power purchase agreements ("PPAs") that have variable interests in VIEs, including 7 tolling agreements through which SCE provides the natural gas to fuel the plants and 10 contracts with qualifying facilities ("QFs") 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 these VIEs is the operation and maintenance of the power plants.

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. Under these

contracts, SCE recovers the costs incurred through demonstration of compliance with its CPUC-approved long-term power procurement plans. 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 9. As a result, there is no significant potential exposure to loss as a result of SCE's involvement with these VIEs. The aggregate capacity dedicated to SCE for these VIE projects was 3,900 MW at September 30, 2012 and the amounts that SCE paid to these projects were $158 million and $178 million for the three months ended September 30, 2012 and 2011 , respectively, and $292 million and $347 million for the nine months ended September 30, 2012 and 2011 , respectively. These amounts are recoverable in customer rates, subject to reasonableness review.

Unconsolidated Trust

In May 2012, SCE Trust I issued $475 million (aggregate liquidation preference) of 5.625% trust securities (cumulative, liquidation amount of $25 per share) to the public and $10,000 of common stock ( 100% ) to SCE. The trust invested the proceeds of these trust securities in Series F Preference Stock issued by SCE in the principal amount of $475 million (cumulative, $2,500 per share liquidation value) and which have substantially the same payment terms as the trust securities. The trust securities and the Series F Preference Stock do not have a maturity date. Upon any redemption of the Series F Preference Stock, a corresponding dollar amount of trust securities will be redeemed (for further information see Note 13). SCE Trust I will pay dividends at the same rate and on the same dates on the trust securities when, and if the SCE board of directors declare and make dividend payments on the Series F Preference Stock. The trust will use the dividends, if any, it receives on the Series F Preference Stock to make its corresponding dividend payments on the trust securities. If SCE does not make dividend payments to the trust, SCE would be prohibited from paying dividends on its common stock. SCE has fully and unconditionally guaranteed the payment of the trust securities and also its dividend payments, if and when, SCE pays dividends on the Series F Preference Stock.

SCE Trust I was formed for the exclusive purpose of issuing trust preference securities (“trust securities”). The trust is a VIE. SCE has concluded that it is not the primary beneficiary of this VIE as it does not have the obligation to absorb the expected losses or the right to receive the expected residual returns of the trust. The trust's balance sheet as of September 30, 2012 , consisted of an investment of $475 million in the Series F Preference Stock, $475 million of trust securities and $10,000 of common stock. The trust's income statement consisted of dividend income and accrued dividend payments of $7 million and $10 million for the three- and nine -months ended September 30, 2012 , respectively.

Note 4. Fair Value Measurements

Recurring Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (referred to as an “exit price”). Fair value of an asset or liability considers assumptions that market participants would use in pricing the asset or liability, including assumptions about nonperformance risk which was not material as of September 30, 2012 and December 31, 2011 .

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

The following table sets forth assets and liabilities that were accounted for at fair value by level within the fair value hierarchy:

The remainder of the unrealized losses relate to SCE. See 2 above.

The fair value for transfers in and transfers out of each level is determined at the end of each reporting period. There were no transfers between Levels 1 and 2 during the three- and nine -month periods ended September 30, 2012 and 2011 .

Valuation Techniques Used to Determine Fair Value

Level 1

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

Level 2

The fair value of Level 2 assets and liabilities is determined using the income approach by obtaining quoted prices for similar assets and liabilities in active markets and inputs that are observable, either directly or indirectly, for substantially the full term of the instrument. This level includes fixed income securities, over-the-counter derivatives and interest rate swaps. For further discussion on fixed income securities, see "—Nuclear Decommissioning Trusts" below.

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

Level 3

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

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

Level 3 Valuation Process

The process of determining fair value is the responsibility of Edison International's subsidiaries' risk management, departments, which report to their respective chief financial officer. These departments obtain observable and unobservable inputs through broker quotes, exchanges and internal valuation techniques that use both standard and proprietary models to determine fair value. Each reporting period, the risk and finance departments collaborate to determine the appropriate fair value methodologies and classifications for each derivative. Inputs are validated for reasonableness by comparison against prior prices, other broker quotes and volatility fluctuation thresholds. Inputs used and valuations are reviewed period-over-period and compared with market conditions to determine reasonableness.

The following table sets forth the valuation techniques and significant unobservable inputs used to determine fair value for Level 3 assets and liabilities at September 30, 2012 :



	Fair Value (in millions)							Significant	Range
	Assets			Liabilities			Valuation Technique(s)	Unobservable Input	(Weighted Average)
Electricity:
Options	$	23		$	26		Option model	Volatility of gas prices	23% - 41% (31%)

Level 3 Fair Value Sensitivity

Gas Options, Electricity Options, and Tolling Arrangements

The fair values of option contracts and tolling arrangements contain intrinsic value and time value. Intrinsic value is the difference between the market price and strike price of the underlying commodity. Time value is made up of several components, including volatility, time to expiration, and interest rates. The fair value of option contracts changes as the underlying commodity price moves away or towards the strike price. The option model for tolling arrangements reflects plant specific information such as operating and start-up costs.

For tolling arrangements and certain gas and power option contracts where Edison International subsidiaries are the buyer, increases in volatility of the underlying commodity prices would result in increases to fair value as it represents greater price

movement risk. As power and gas prices increase, the fair value of the option contracts and tolling arrangements tends to increase. The valuation of power option contracts and tolling arrangements is also impacted by the correlation between gas and power prices. As the correlation increases, the fair value of power option contracts and tolling arrangements tends to decline.

Forward Power Contracts

Generally, an increase (decrease) in long-term forward power prices at illiquid locations where Edison International subsidiaries are the seller relative to the contract price will decrease (increase) fair value. Inversely as a buyer, an increase (decrease) in long-term forward power prices at illiquid locations relative to the contract price will increase (decrease) fair value.

Congestion Contracts

When valuation is based on a discounted cash flow model and Edison International subsidiaries are the buyer, generally an increase (decrease) in congestion prices in the last auction relative to the contract price will increase (decrease) fair value.

When valuation is based on a market simulation model and Edison International subsidiaries are the buyer, generally increases (decreases) in forecasted load would result in increases (decreases) to fair value. In general, increases (decreases) in electricity and gas prices at illiquid locations tends to result in increases (decreases) to fair value; however, changes in electricity and gas prices in opposite directions may have varying results on fair value.

Nuclear Decommissioning Trusts

SCE's 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.

Fair Value of Long-Term Debt Recorded at Carrying Value

The carrying value and fair value of long-term debt are:



	September 30, 2012				December 31, 2011
(in millions)	Carrying Value		Fair Value		Carrying Value		Fair Value
Long-term debt, including current portion	$	14,273	$	14,452	$	13,746	$	14,264

Fair value of short-term and long-term debt is classified as Level 2 and 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 of new issue prices and relevant credit information.

The carrying value of trade receivables and payables, other investments, and short-term debt approximates fair value.

Note 5. Debt and Credit Agreements

Project Financings

Broken Bow and Crofton Bluffs

Effective March 30, 2012 , EME, through its subsidiaries, Broken Bow Wind, LLC and Crofton Bluffs Wind, LLC, completed two nonrecourse financings of its interests in the Broken Bow and Crofton Bluffs wind projects. The financings included construction loans totaling $79 million that are required to be converted to 15 -year amortizing term loans by March 31, 2013, subject to meeting specified conditions, $13 million letter of credit facilities and $6 million working capital facilities. Interest under the construction and term loans will accrue at London Interbank Offered Rate ( LIBOR ) plus 2.875% , with the term loan rate increasing 0.125% after the third, sixth, ninth, and twelfth years. As of September 30, 2012 , $21 million and $6 million were outstanding under the construction loans included in short-term debt on EME's consolidated balance sheet, and letters of credit facilities, respectively.

Tapestry Wind

In December 2011, EME through its subsidiary, Tapestry Wind, LLC, completed a nonrecourse financing of its interests in the Taloga, Buffalo Bear and Pinnacle wind projects. A total of $97 million of cash proceeds received from the $214 million 10 -year partially amortizing term loan was deposited into an escrow account as of December 31, 2011. On February 22, 2012 , a neighbor of the Pinnacle project, filed a formal complaint with the West Virginia Public Service Commission regarding, among other things, noise emissions and shadow flicker and requested that the Commission order the project to shut down at night due to alleged noise emissions. This complaint was dismissed on June 1, 2012. On June 27, 2012 and on July 3, 2012, nearly identical complaints were filed with the West Virginia Public Service Commission by two other neighbors and were subsequently dismissed. In addition, on June 25, 2012, each of the three neighbors filed separate civil complaints in the Circuit Court of Mineral County, West Virginia against Pinnacle Wind, LLC, EME, Edison Mission Operations and Maintenance, Inc., and other non-affiliated defendants. The civil complaints allege, among other things, that the noise emissions and shadow flicker from the Pinnacle wind farm constitute a nuisance and seek compensatory damages, punitive damages and other equitable relief. The complaints have been dismissed without prejudice. The release of the loan proceeds in escrow is subject to final resolution of the complaints or further due diligence from the lenders.

Big Sky Turbine Financing

In October 2009, EME, through its subsidiary, Big Sky Wind, LLC (Big Sky), entered into turbine financing arrangements with the turbine manufacturer, totaling approximately $206 million for wind turbine purchase obligations related to the 240 MW Big Sky wind project. The loan has a five -year final maturity, however, specific events, including project performance, may trigger earlier repayment which could occur as early as February 2013. Big Sky is currently involved in a dispute with the lender/turbine manufacturer around whether certain latent defects existing in the turbine equipment would preclude the early repayment provisions. The loan is secured by a leasehold mortgage on the project's real property assets, a pledge of all other collateral of the Big Sky wind project, as well as a cash reserve account into which one-third of distributable cash flow, if any, of the Big Sky wind project is to be deposited on a monthly basis. The loan is also secured by pledges of Big Sky's direct and indirect ownership interests in the project but is non-recourse to EME.

Big Sky will need to arrange alternative financing, if available, to repay the loan at maturity or reach agreement with the lender to extend the maturity date of the loan as EME does not plan to make an investment in the project and is under no obligation to do so. If these efforts are unsuccessful, the lender may foreclose on the project resulting in a write off of the entire investment in the project. At September 30, 2012 , EME's net investment in the Big Sky wind project was $130 million .

Long-Term Debt

In March 2012, SCE issued $400 million of 4.05% first and refunding mortgage bonds due in 2042. The proceeds from these bonds were used to repay commercial paper borrowings and to fund SCE's capital program.

Credit Agreements and Short-Term Debt

During the second quarter of 2012, SCE replaced its credit facilities with a $2.75 billion five-year revolving credit facility that matures in May 2017 . The credit facility is generally used to support commercial paper and letters of credit issued for procurement-related collateral requirements, balancing account undercollections and for general corporate purposes, including working capital requirements to support operations and capital expenditures. At September 30, 2012 , SCE's outstanding commercial paper supported by the credit facility was $380 million at a weighted-average interest rate of 0.43% . At September 30, 2012 , letters of credit issued under SCE's credit facility aggregated $196 million and are scheduled to expire in twelve months or less. At December 31, 2011 , the outstanding commercial paper was $419 million at a weighted-average interest rate of 0.44% .

In February 2012, EME terminated its $564 million revolving credit facility. Midwest Generation's $500 million credit facility expired in June 2012 as per its terms. In the first quarter of 2012, EME completed a $100 million letter of credit facility for EME's general corporate needs and for its projects, which expires on June 30, 2014 . Letters of credit issued under this facility are secured by cash collateral at least equal to the issued amount.

During the second quarter of 2012, Edison International (parent) replaced its credit facility with a $1.25 billion five-year revolving credit facility that matures in May 2017. Borrowings under this credit facility are used for general corporate purposes. At September 30, 2012 , Edison International (parent) outstanding short-term debt supported by this credit facility was $28 million at a weighted-average interest rate of 1.52% . At December 31, 2011 , the outstanding short-term debt was $10 million at a weighted-average interest rate of 0.66% .

Letters of Credit

At September 30, 2012 , letters of credit under EME's and its subsidiaries' credit facilities aggregated $154 million . EME had $51 million of cash collateral supporting its letters of credit which were scheduled to expire as follows: $48 million in 2013 and $3 million in 2014. In addition, EME's subsidiaries' credit facilities aggregated $103 million and were scheduled to expire as follows: $2 million in 2012, $49 million in 2013, $21 million in 2017, $18 million in 2018 and $13 million in 2021. Standby letters of credit include $30 million issued in connection with the power purchase agreement with SCE under the Walnut Creek credit facility. Certain letters of credit are subject to automatic annual renewal provisions.

Note 6. 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 customer exposure to variability in market prices related to SCE's power and gas activities. As part of this program, SCE enters into options, swaps, forwards, tolling arrangements and CRRs. These transactions are approved by the CPUC or executed in compliance with CPUC-approved procurement plans. SCE recovers its related hedging costs through the energy resource recovery account ("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 purchased from and sold to wholesale markets as a result of differences between SCE's load requirements and the amount of energy delivered from its generating facilities and power purchase agreements.

SCE's natural gas price exposure arises from natural gas purchased for the Mountainview power plant and peaker plants, QF contracts where pricing is based on a monthly natural gas index and power purchase agreements in which SCE has agreed to provide the natural gas needed for generation, referred to as tolling arrangements.

Income Statement Impact of Derivative Instruments

SCE recognizes realized gains and losses on derivative instruments as purchased power expense and expects that such gains or losses will be part of the purchase power costs recovered from customers. As a result, realized gains and losses do not affect earnings, but may temporarily affect cash flows. Due to expected future recovery from customers, unrealized gains and losses are recorded as regulatory assets and liabilities and therefore also do not affect 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.

The following table summarizes the components of economic hedging activity:



	Three months ended September 30,						Nine months ended September 30,
(in millions)	2012			2011			2012			2011
Realized gains (losses)	$	(77	)	$	(58	)	$	(199	)	$	(132	)
Unrealized gains (losses)	(91		)	(110		)	(29		)	(433		)

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 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 $113 million and $216 million as of September 30, 2012 and December 31, 2011 , respectively, for which SCE has posted no collateral to its counterparties for the respective periods. If the credit-risk-related contingent features underlying these agreements were triggered on September 30, 2012 , SCE would be required to post $25 million of collateral.

Counterparty Default Risk Exposure

As part of SCE's procurement activities, SCE contracts with a number of utilities, energy companies, financial institutions and other companies, collectively referred to as counterparties. If a counterparty were to default on its contractual obligations, SCE could be exposed to potentially volatile spot markets for buying replacement power or selling excess power. In addition, SCE would be exposed to the risk of non-payment of accounts receivable, primarily related to sales of excess energy and realized gains on derivative instruments. Substantially all of the contracts that SCE has executed with counterparties are either entered into under SCE's procurement plan which has been pre-approved by the CPUC, or the contracts are approved by the CPUC before becoming effective. As a result of regulatory recovery mechanisms, losses from non-performance are not expected to affect earnings, but may temporarily affect cash flows.

To manage credit risk, SCE looks at the risk of a potential default by counterparties. Credit risk is measured by the loss that would be incurred if counterparties failed to perform pursuant to the terms of their contractual obligations. To mitigate credit risk from counterparties, master netting agreements are used whenever possible and counterparties may be required to pledge collateral when deemed necessary.

Competitive Power Generation

EMG's subsidiary, EME uses derivative instruments to reduce its exposure to market risks that arise from price fluctuations of electricity, capacity, fuel, emission allowances, transmission rights and interest rates. The derivative financial instruments vary in duration, ranging from a few days to several years, depending upon the instrument. To the extent that EME 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 the consolidated balance sheets as derivative assets or liabilities with offsetting changes recorded on the consolidated statements of operations. For derivative instruments that qualify for hedge accounting treatment, the fair value is recognized on the consolidated balance sheets as derivative assets or liabilities with offsetting changes in fair value, to the extent effective, recognized in accumulated other comprehensive loss until reclassified into earnings when the related forecasted transaction occurs. The portion of a cash flow hedge that does not offset the change in the fair value of the transaction being hedged, which is commonly referred to as the ineffective portion, is immediately recognized in earnings.

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

The results of derivative activities are recorded in cash flows from operating activities on the consolidated statements of cash flows.

Where EME's derivative instruments are subject to a master netting agreement and the criteria of authoritative guidance are met, derivative assets and liabilities are presented on a net basis on the consolidated balance sheets.

¹	EME's hedge transactions for capacity result from bilateral trades. Capacity sold in the PJM Interconnection, LLC Reliability Pricing Model (PJM RPM) auction is not accounted for as a derivative.


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


³	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.

At December 31, 2011 , EME had interest rate contracts with notional values totaling $644 million that converted floating rate LIBOR-based debt to fixed rates ranging from 0.79% to 4.29% .

Contingent Features

Certain derivative instruments contain margin and collateral deposit requirements. Since EME's and its subsidiaries' credit ratings are below investment grade, EME and its subsidiaries have provided collateral in the form of cash and letters of credit for the benefit of derivative counterparties.

Margin and Collateral Deposits

Margin and collateral deposits include cash deposited with counterparties and brokers, and cash received from counterparties and brokers as credit support under energy contracts. The amount of margin and collateral deposits generally varies based on changes in the fair value of the related positions. Edison International nets counterparty receivables and payables where balances exist under master netting agreements. Edison International presents the portion of its margin and collateral deposits netted with its derivative positions on its consolidated balance sheets. The following table summarizes margin and collateral deposits provided to and received from counterparties:

The CPUC requires flow-through ratemaking 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.

As of September 30, 2012 and December 30, 2011, respectively, if recognized, $578 million and $532 million of the unrecognized tax benefits would impact the effective tax rate.

Tax Dispute

Edison International's federal income tax returns and its California combined franchise tax returns are currently open for years subsequent to 2002. In addition, specific California refund claims made by Edison International for years 1991 through 2002 are currently under review by the Franchise Tax Board. The IRS examination phase of tax years 2003 through 2006 was completed in the fourth quarter of 2010, which included proposed adjustments for the following two items:


•	A proposed adjustment increasing the taxable gain on the 2004 sale of EME's international assets, which if sustained, would result in a federal tax payment of approximately $198 million , including interest and penalties through September 30, 2012 (the IRS has asserted a 40% penalty for understatement of tax liability related to this matter).


•	A proposed adjustment to disallow a component of SCE's repair allowance deduction, which if sustained, would result in a federal tax payment of approximately $95 million , including interest through September 30, 2012 .

Edison International disagrees with the proposed adjustments and filed a protest with the IRS in the first quarter of 2011. The appeals process to date has not resulted in a change in the proposed adjustment by the IRS on the taxable gain on the 2004 sale of EME's international assets. If a deficiency notice is issued on this item, it would require payment of the tax, interest and any penalties within 90 days of its issuance or a filing of a petition in United States Tax Court.

Tax Election at Homer City

On March 15, 2012, Homer City made an election to be treated as a partnership for federal and state income tax purposes. As a result of this election, Homer City is treated for tax purposes as distributing its assets and liabilities to its partners, both of which are wholly owned subsidiaries of EME, and triggering tax deductions of approximately $1.0 billion . Such tax deductions were included in Edison International's 2011 consolidated tax returns.

Loss and Credit Carryforwards

Including the tax deduction generated from the Homer City election, Edison International has recorded tax benefits for federal and state net operating loss carryforwards and federal tax credit carryforwards of approximately $ 1.6 billion as of September 30, 2012 .

Repair Deductions

In 2009, Edison International made a voluntary election to change its tax accounting method for certain repair costs incurred on SCE's transmission, distribution and generation assets. In August 2011, the IRS issued guidance on repair deductions and changes in accounting method related to transmission and distribution assets. Based on this guidance, SCE included a second change in tax accounting method on repair costs in its 2011 tax return. Guidance for generation assets is pending. Regulatory treatment for the incremental deductions taken after the voluntary election to change SCE's tax accounting method for certain repair costs is part of SCE's 2012 GRC. Due to the pending regulatory decision, SCE has not recognized an earnings benefit or regulatory asset related to this method change and incremental deductions taken in 2009, 2010 and 2011. In October 2012, the CPUC assigned administrative law judge issued a proposed GRC decision, which if adopted, would result in an earnings

benefit of approximately $230 million attributable to flow through treatment of 2009 – 2011 vintage year activity. SCE would also record an earnings benefit related to 2012 vintage year activity consistent with the rate making treatment.

Note 8. Compensation and Benefit Plans

Pension Plans

As part of the pension funding provisions contained in the Surface Transportation Extension Act of 2012 passed by Congress, Edison International's projected 2012 plan contributions have been reduced to $180 million from $286 million , which resulted in a third quarter regulatory adjustment reflected in the table below. Contributions of $156 million were made during the nine months ended September 30, 2012 . The 2012 GRC proposed decision authorized contributions of $168 million with recovery of any undercollection through the continuation of the existing balancing account mechanism. A final GRC decision is expected by year-end. Annual contributions to these plans are expected to be, at a minimum, equal to the related annual expense.

Expense components are:

Postretirement Benefits Other Than Pensions

Edison International made contributions of $17 million during the nine months ended September 30, 2012 and expects to make $48 million of additional contributions during the remainder of 2012 . In 2012 , annual contributions made to plans for SCE employees are expected to be recovered through CPUC-approved regulatory mechanisms. Annual contributions are expected to be, at a minimum, equal to the total annual expense for these plans. Benefits under these plans, with some exceptions, are generally unvested and subject to change.

¹	Due to the reduction in the workforce at San Onofre, Edison International has incurred costs for enhanced retiree health care coverage. See below for further information.

San Onofre Workforce Reduction

In August 2012, SCE announced plans for downsizing to bring the San Onofre organization and cost structure in line with industry peers. SCE plans to reduce the San Onofre workforce by 730 employees to 1,500 employees beginning in the fourth quarter of 2012 and continuing in 2013. At September 30, 2012, SCE had recorded $30 million in estimated cash severance costs (SCE's share) related to the non-represented employee workforce reduction.

Note 9. Commitments and Contingencies

Third-Party Power Purchase Agreements

During the nine months ended September 30, 2012 , SCE had power purchase contracts with additional commitments estimated to be: $17 million in 2014, $43 million in 2015, $66 million in 2016 and $970 million for the period remaining thereafter. Some of these power purchase agreements are classified as operating leases. The additional commitments for these leases, which are also included in the amounts above, are estimated to be: $21 million in 2015, $45 million in 2016 and $942 million for the period remaining thereafter.

Coal Transportation Agreements

At September 30, 2012 , Midwest Generation had contractual agreements for the transportation of coal. The commitments under these contracts are based on either actual coal purchases derived from committed coal volumes set forth in fuel supply contracts or minimum quantities as set forth in the transportation agreements as adjusted for provisions that mitigate the financial exposure of Midwest Generation related to a plant closure under certain circumstances as specified in the agreements. Estimated contractual obligations for coal transportation agreements are estimated to aggregate $2.3 billion , which consists of: $118 million for the remainder of 2012, $292 million for 2013, $286 million for 2014, $260 million for 2015, $260 million for 2016 and $1.1 billion thereafter. Years subsequent to 2012 reflect a reduction in minimum volumes for the shutdown of the Fisk and Crawford Stations.

Capital Commitments

At September 30, 2012 , EMG's subsidiaries had firm commitments to spend approximately $92 million during the remainder of 2012, $44 million for 2013 and $17 million for 2015 for capital expenditures. These expenditures primarily relate to the Walnut Creek project, construction of wind projects and capital expenditures at the Midwest Generation plants.

Homer City Lease

Homer City received a forbearance of the $47 million senior rent payment due October 1, 2012. Homer City made the required April 1, 2012 senior rent payment of $48 million but did not make the April 1, 2012 payment of equity rent of $65 million and was granted a waiver by the owner-lessors of any rent default event with respect to the payment of the equity rent for all purposes other than restrictions on distributions from Homer City, including repayment of its intercompany loan, and the $48 million senior rent reserve letter of credit remains in place. Homer City and an affiliate of GECC entered into the Homer City MTA for the divestiture by Homer City of substantially all of its remaining assets and certain specified liabilities. For further discussion, see Note 18.

Guarantees and Indemnities

Edison International's subsidiaries have various financial and performance guarantees and indemnity agreements which are issued in the normal course of business. The contracts discussed below included performance guarantees.

Environmental Indemnities Related to the Midwest Generation Plants

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

that it believes it is entitled to indemnification for costs and expenses incurred in connection with the information requested under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 regarding environmental sampling and investigation performed at Midwest Generation's Fisk and Crawford sites. Except as discussed below, EME has not recorded a liability related to these environmental indemnities.

Midwest Generation entered into a supplemental agreement with Commonwealth Edison and Exelon Generation Company LLC on February 20, 2003 to resolve a dispute regarding interpretation of Midwest Generation's reimbursement obligation for asbestos claims under the environmental indemnities set forth in the Asset Sale Agreement. Under this supplemental agreement, Midwest Generation agreed to reimburse Commonwealth Edison and Exelon Generation for 50% of specific asbestos claims pending as of February 2003 and related expenses less recovery of insurance costs, and agreed to a sharing arrangement for liabilities and expenses associated with future asbestos-related claims as specified in the agreement. The obligations under this agreement are not subject to a maximum liability. The supplemental agreement had an initial five -year term with an automatic renewal provision for subsequent one -year terms (subject to the right of either party to terminate); pursuant to the automatic renewal provision, the supplemental agreement has been extended until February 2013. There were approximately 230 cases for which Midwest Generation was potentially liable that had not been settled and dismissed at September 30, 2012 . Midwest Generation had recorded a liability of $53 million at September 30, 2012 related to this contractual indemnity.

Indemnities Related to the Homer City Plant

In connection with the original acquisition of the Homer City plant, Homer City agreed to indemnify the sellers with respect to specified environmental liabilities before and after the date of sale. EME guaranteed this obligation of Homer City. Also, in connection with the sale-leaseback transaction related to the Homer City plant, Homer City agreed to indemnify the owner-lessors for specified environmental liabilities. Due to the nature of the obligations under these indemnity provisions, they are not subject to a maximum potential liability and do not have expiration dates. EME has not recorded a liability related to this indemnity. For discussion of the New Source Review lawsuit filed against Homer City, see "—Contingencies—Homer City New Source Review and Other Litigation."

Indemnities Provided under Asset Sale and Sale-Leaseback Agreements

The asset sale agreements for the sale of EME's international assets contain indemnities from EME to the purchasers, including indemnification for taxes imposed with respect to operations of the assets prior to the sale and for pre-closing environmental liabilities. Not all indemnities under the asset sale agreements have specific expiration dates. At September 30, 2012 , EME had recorded a liability of $20 million related to these matters.

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

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

Upon closing of the Homer City MTA, the tax indemnity agreements between EME, Homer City and GECC will be terminated and GECC will release EME and Homer City from its obligations thereunder. Completion of the Homer City MTA is subject to the satisfaction of a number of closing conditions, including the successful restructuring and reorganization of an affiliate of GECC and receipt of the regulatory approvals required for the transfer of the Homer City plant to GECC. For further discussion, see Note 18.

Indemnity Provided as Part of the Acquisition of Mountainview

In connection with the acquisition of the Mountainview power plant, 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.

Mountainview Filter Cake Indemnity

SCE has indemnified the City of Redlands, California in connection with Mountainview's California Energy Commission permit 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 and Guarantees

EME guarantees Midwest Generation's payments under the Powerton and Joliet sale-leaseback agreements. A default by Midwest Generation in meeting its obligations under those agreements could have an adverse impact on EME.

Edison International 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 indemnities for specified environmental liabilities and income taxes with respect to assets sold. Edison International's obligations under these agreements may or may not be limited in terms of time and/or amount, and in some instances Edison International may have recourse against third parties. Edison International has not recorded a liability related to these indemnities. The overall maximum amount of the obligations under these indemnifications cannot be reasonably estimated.

Contingencies

In addition to the matters disclosed in these Notes, 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 the outcome of these other proceedings will not, individually or in the aggregate, materially affect its results of operations or liquidity.

Midwest Generation New Source Review and Other Litigation

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

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

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

In October 2012, Midwest Generation and the Illinois Environmental Protection Agency entered into Compliance Commitment Agreements outlining specified environmental remediation measures and groundwater monitoring activities to be undertaken at its Powerton, Joliet, Crawford, Will County and Waukegan generating stations. Also in October 2012, several environmental groups filed a complaint before the Illinois Pollution Control Board against Midwest Generation, alleging violations of the Illinois groundwater standards through the operation of coal ash disposal ponds at its Powerton, Joliet, Waukegan and Will County generating stations. The complaint requests the imposition of civil penalties, injunctive relief and remediation.

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

Homer City New Source Review and Other Litigation

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

Also in January 2011, two residents filed a complaint in the Western District of Pennsylvania, on behalf of themselves and all others similarly situated, against Homer City, the sale-leaseback owner participants of the Homer City plant, two prior owners of the Homer City plant, EME, and Edison International, claiming that emissions from the Homer City plant had adversely affected their health and property values. The plaintiffs sought to have their suit certified as a class action and requested injunctive relief, the funding of a health assessment study and medical monitoring, as well as compensatory and punitive damages. In October 2011, the claims in the purported class action lawsuit that were based on the federal CAA were dismissed with prejudice, while state law statutory and common law claims were dismissed without prejudice to re-file in state court should the plaintiffs choose to do so. EME does not know whether the plaintiffs will file a complaint in state court.

In February 2012, Homer City received a 60 -day Notice of Intent to Sue indicating the Sierra Club’s intent to file a citizen lawsuit alleging violations of emissions standards and limitations under the CAA and the Pennsylvania Air Pollution Control Act.

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

San Onofre Outage, Inspection and Repair Issues

SCE replaced four steam generators at San Onofre Units 2 and 3 in 2010 and 2011, respectively. In the first quarter of 2012, a water leak suddenly occurred in one of the heat transfer tubes in San Onofre's Unit 3 steam generators. Unit 3 was safely taken off-line. At the time, San Onofre Unit 2 was off-line for a planned outage when areas of unexpected wear in some of its heat transfer tubes were found. Both Units have remained off-line for extensive inspections, testing and analysis of their steam generators. Each Unit will be restarted only when and if SCE determines that it is safe to do so and when start-up has been approved by the NRC pursuant to the terms of a Confirmatory Action Letter (“CAL”) issued by the NRC in March 2012. The CAL requires NRC permission to restart Unit 2 and Unit 3 and outlines actions SCE must complete before

permission to restart either Unit may be sought. In October 2012, SCE submitted to the NRC a response to the CAL and restart plans for Unit 2. SCE proposed to restart Unit 2 and operate at a reduced power level ( 70% ) for approximately five months, followed by a mid-cycle scheduled outage.

In 2005, the CPUC authorized expenditures of approximately $525 million ( $665 million after adjustment for inflation) for SCE's 78.21% share of San Onofre to purchase and install the four new steam generators in Units 2 and 3 and remove and dispose of their predecessors. SCE has spent $594 million through September 30, 2012 on the steam generator replacement project, including $95 million reflected in construction work in progress primarily related to the disposal of the replaced steam generators. Those expenditures remain subject to CPUC reasonableness review. Final costs for the project will not be known until after disposal of the original steam generators is completed.

As a result of outages associated with the steam generator inspection and repair, electric power and capacity normally provided by San Onofre are being purchased in the market by SCE (commencing on February 1 for Unit 3 and March 5 for Unit 2). Market costs through September 30, 2012 were approximately $221 million , net of avoided nuclear fuel costs, and are recoverable through the ERRA balancing account subject to CPUC reasonableness review. Because of the uncertainties associated with when and at what output levels the Units will or may be returned to service, total potential market power costs cannot be estimated at this time.

Through September 2012, SCE's share of incremental inspection and repair costs totaled $96 million for both Units. At September 30, 2012, the repairs to restart Unit 2 at the reduced power levels described above have been substantially completed. The costs for Unit 2 may increase following NRC review under the CAL and any new developments that may result from further analysis, testing and inspection, and there is no assurance that start-up of Unit 2 will occur as described above. Total incremental repair costs associated with returning Unit 3 to service, and returning both Units to service at originally specified capabilities safely, remain uncertain.

In addition to the amounts for inspection and repair and market power costs discussed below, SCE has collected through customer rates an estimated $625 million of revenue through third quarter 2012 (based on current authorized revenue requirements) associated with the plant. SCE's total 2012 San Onofre annual revenue requirement, including the 2012 GRC proposed decision, is approximately $820 million , made up of $170 million in refueling outage, nuclear fuel and decommissioning costs and $650 million for its direct operating and maintenance costs, depreciation and return on its investment in San Onofre Unit 2, Unit 3 and related common plant. At September 30, 2012, SCE's rate base and net investment and inventory associated with San Onofre was $1.2 billion and $2.1 billion , respectively.

Under California Public Utilities Code Section 455.5, SCE is required to notify the CPUC if either of the San Onofre Units has been out of service for nine consecutive months (not including preplanned outages). SCE will provide such notice to the CPUC on November 1, 2012 for Unit 3 and expects to do so by December 6, 2012 for Unit 2. The CPUC is required within 45 days of SCE's notice for a particular Unit to initiate an investigation to determine whether to remove from customer rates some or the entire revenue requirement associated with the portion of the facility that is out of service. From the initiation date of the investigation, such rates are collected subject to refund. Under Section 455.5 any determination to adjust rates is made after hearings are conducted in connection with the utility's next general rate case. If, after investigation and hearings, the costs associated with a Unit are disallowed recovery because it is out of service and the Unit is subsequently returned to service, rates may be readjusted to reflect that return to service after 100 continuous hours of operation.

In October 2012, in advance of SCE's required notification under Section 455.5, the CPUC issued an order instituting investigation ("OII") that will consolidate all San Onofre issues in related regulatory proceedings and consider appropriate cost recovery for all San Onofre costs, including among other costs, the cost of the steam generator replacement project, market power costs, capital and operations and maintenance costs, and seismic study costs. The order requires that all San Onofre-related costs incurred on and after January 1, 2012 be tracked in a memorandum account and, to the extent included in rates, collected subject to refund. The order also states that the CPUC will determine whether to order the immediate removal, effective as of the date of the order, of all costs related to San Onofre from SCE's rates, with placement of those costs in a deferred debit account pending the return of one or both Units to useful service, or other possible action. SCE will file its response to the order by November 26, 2012. SCE must also file testimony by December 10, 2012 detailing proposed rate adjustments due to the outages, including the amount of San Onofre costs in current rates, the amount to be removed, if any, the effective date, and related information. A pre-hearing conference will be scheduled early in 2013 after the issuance of a Scoping Memo by the Assigned Commissioner.

through 2011 for the high pressure turbine project, but disallows recovery for post-2011 expenditures associated with the project and directs SCE to record those costs in either the memorandum account or seek future rate recovery in the next GRC. SCE anticipates that the inter-relationship between the Section 455.5 process and the issues to be reviewed in the investigation or pursuant to a final decision in the GRC will be addressed by the CPUC as it continues to develop the scope of the issues to be consolidated within the investigation.

The steam generators were designed and supplied by MHI and are warranted for an initial period of 20 years from acceptance. MHI is contractually obligated to repair or replace defective items and to pay specified damages for certain repairs. SCE's purchase contract with MHI states that MHI's liability under the purchase agreement is limited to $138 million and excludes consequential damages, defined to include "the cost of replacement power." Such limitations in the contract are subject to applicable exceptions. In September 2012, SCE submitted an invoice to MHI for costs paid through June 30, 2012 in the amount of $45 million for both SCE's and the other co-owners' share of steam generator repair costs. SCE expects to continue to invoice MHI for costs incurred. No amounts have been recognized in the financial statements as of September 30, 2012.

San Onofre carries both property damage and outage insurance issued by Nuclear Electric Insurance Limited (“NEIL”) and has placed NEIL on notice of potential claims for loss recovery. In October 2012, SCE filed separate proofs of loss for Unit 2 and Unit 3 under the outage policy. Pursuant to these proofs of loss SCE is seeking the weekly indemnity amounts provided under the policy for each Unit. Because the outage is ongoing, SCE will supplement these proofs of loss in the future. No amounts have been recognized in SCE's financial statements, pending further actions by NEIL. To the extent any costs are recovered under the outage policy, SCE expects to refund those amounts to ratepayers through the ERRA balancing account.

SCE will pursue recoveries arising from available agreements, but there is no assurance that SCE will recover all of its applicable costs pursuant to these arrangements.

CPSD Investigations

San Gabriel Valley Windstorm Investigation

In November 2011, a windstorm resulted in significant damage to SCE’s electric system and service outages for SCE customers primarily in the San Gabriel Valley. The CPUC directed its Consumer Protection and Safety Division (“CPSD”) to conduct an investigation focused on the cause of the outages, SCE’s service restoration effort, and SCE’s customer communications during the outages. The CPSD issued its preliminary report on February 1, 2012. The report asserts that SCE and others with whom SCE shares utility poles violated certain CPUC safety rules applicable to overhead line construction, maintenance and operation, which may have caused the failures of affected poles and supporting cables. The report also concludes that SCE’s restoration time was not adequate and makes other assertions. Additionally, the report contends that SCE violated CPUC rules by failing to preserve evidence relevant to the investigation when it did not retain damaged poles that were replaced following the windstorm. If the CPUC issues an OII regarding this matter and SCE is found to have violated any CPUC rules, it could face penalties. SCE is unable to estimate a possible loss or range of loss associated with any penalties that may be imposed by the CPUC on SCE.

The proposed decision in SCE’s 2012 GRC would direct SCE to, among other things, make an assessment of a representative sampling of its loaded poles to determine their conformance with current legal standards and report by January 31, 2013 on the results of this assessment. The cost of any large scale review of poles or other equipment for safety compliance, as well as any remediation measures required to assure compliance, could be significant.

Malibu Fire Order Instituting Investigation

Following a 2007 wildfire in Malibu, California, the CPUC issued an OII to determine if any statutes, CPUC general orders, rules or regulations were violated by SCE or telecomm providers (“OII Respondents”) that shared the use of three failed power poles in the wildfire area. The CPSD has alleged, among other things, that the poles were overloaded, that the OII Respondents violated the CPUC's rules governing the design, construction and inspection of poles and misled the CPUC during its investigation of the fire, and that SCE failed to preserve evidence relevant to the investigation. In October 2011, the CPSD proposed that the OII Respondents be assessed penalties of approximately $99 million , with SCE being allocated approximately $50 million of the total. SCE has denied the allegations and believes the proposed penalties are excessive. In September 2012, the CPUC approved a partial settlement between the CPSD and three telecomm providers, leaving SCE and a non-settling telecomm provider as the remaining respondents. The partial settlement did not resolve any of the claims against SCE or the remaining telecomm provider.

Four Corners New Source Review Litigation

In October 2011 , four private environmental organizations filed a CAA citizen lawsuit against the co-owners of Four Corners. The complaint alleges that certain work performed at the Four Corners generating units 4 and 5, over the approximate periods of 1985 - 1986 and 2007 -present, constituted plant “major modifications” and the plant's failure to obtain permits and install best available control technology ("BACT") violated the PSD requirements and the New Source Performance Standards of the CAA. The complaint also alleges subsequent and continuing violations of BACT air emissions limits. The lawsuit seeks injunctive and declaratory relief, civil penalties, including a mitigation project and litigation costs. In November 2010 , SCE entered into an agreement to sell its ownership interest in generating units 4 and 5 to APS. The sale is subject to certain closing conditions, including APS obtaining a long-term fuel supply agreement for the plant, and is expected to close no earlier than December 2012 . Under the agreement SCE would remain responsible for its pro rata share of certain environmental liabilities, including penalties arising from environmental violations prior to the sale, but SCE would not be liable for any costs of installing BACT or other costs related to continuing or extending Four Corners operations. SCE is unable to estimate a possible loss or range of loss associated with this matter.

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 costs for site investigations, remediation, operation and maintenance, monitoring and site closure. Unless there is a single 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 timing of cash flows is uncertain.

At September 30, 2012 , Edison International's recorded estimated minimum liability to remediate its 27 identified material sites (sites in which the upper end of the range of the costs is at least $1 million ) at SCE ( 25 sites) and EME ( 2 sites related to Midwest Generation) was $121 million , of which $113 million was related to SCE, including $78 million related to San Onofre. In addition to its identified material sites, SCE also has 33 immaterial sites for which the total minimum recorded liability was $3 million . Of the $116 million total environmental remediation liability for SCE, $113 million has been recorded as a regulatory asset. SCE expects to recover $31 million through an incentive mechanism that allows SCE to recover 90% of its environmental remediation costs at certain sites (SCE may request to include additional sites) and $82 million through a mechanism that allows SCE to recover 100% of the costs incurred at certain sites 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.

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 the identified material sites and immaterial sites could exceed its recorded liability by up to $185 million and $6 million , respectively, 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.

SCE expects to clean up and mitigate its identified sites over a period of up to 30 years. Remediation costs for 2012 and in each of the next four years are expected to range from $7 million to $14 million . Costs incurred for the nine months ended September 30, 2012 and 2011 were $5 million and $9 million , respectively.

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 estimates.

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.

NEIL, a mutual insurance company owned by entities with nuclear facilities, issues primary property damage, decontamination and excess property damage and accidental outage insurance policies. At San Onofre and Palo Verde, property damage insurance covers losses up to $500 million , including decontamination costs. Decontamination liability and excess property damage coverage exceeding the primary $500 million also has been purchased in amounts greater than the federal requirement of a minimum of approximately $1.1 billion . Property damage insurance also covers damages caused by acts of terrorism up to specified limits. Additional outage insurance covers part of replacement power expenses during an accident-related nuclear unit outage.

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 $49 million per year. Insurance premiums are charged to operating expense.

Wildfire Insurance

Severe wildfires in California have given rise to large damage claims against California utilities for fire-related losses alleged to be the result of the failure of electric and other utility equipment. Invoking a California Court of Appeal decision, plaintiffs pursuing these claims have relied on the doctrine of inverse condemnation, which can impose strict liability (including liability for a claimant's attorneys' fees) for property damage. On September 15, 2012 , SCE's parent, Edison International, renewed its insurance coverage, which included coverage for SCE's wildfire liabilities up to a $550 million limit (with a self-insured retention of $10 million per wildfire occurrence). Various coverage limitations within the policies that make up the insurance coverage could result in additional self-insured costs in the event of multiple wildfire occurrences during the policy period ( September 15, 2012 to August 31, 2013 ). SCE may experience coverage reductions and/or increased insurance costs in future years. No assurance can be given that future losses will not exceed the limits of SCE's insurance coverage.

Spent Nuclear Fuel

Under federal law, the Department of Energy ("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 June 2010 , the United States Court of Federal Claims issued a decision granting SCE and the San Onofre co-owners damages of approximately $142 million to recover costs incurred through December 31, 2005 for the DOE's failure to meet its obligation to begin accepting spent nuclear fuel from San Onofre. SCE received payment from the federal government in the amount of the damage award in November 2011. SCE has returned to the San Onofre co-owners their respective share of the damage award paid. SCE, as operating agent, filed a lawsuit on behalf of the San Onofre owners against the DOE in the Court of Federal Claims in December 2011 seeking damages of approximately $98 million for the period from January 1, 2006 to December 31, 2010 for the DOE's failure to meet its obligation to begin accepting spent nuclear fuel. Additional legal action would be necessary to recover damages incurred after December 31, 2010. Any damages recovered by SCE are subject to CPUC review as to how these amounts would be distributed among customers, shareholders, or to offset fuel decommissioning or storage costs.

Note 10. Environmental Developments

Cross-State Air Pollution Rule

In August 2012, the U.S. Court of Appeals for the District of Columbia Circuit vacated the US EPA's Cross-State Air Pollution Rule ("CSAPR") and directed the US EPA to continue administering the Clean Air Interstate Rule pending the promulgation of a valid replacement. In October 2012, the US EPA filed a petition seeking to have the decision reviewed by the full District of Columbia Circuit.

Hazardous Air Pollutant Regulations

In December 2011, the US EPA announced the Mercury and Air Toxics Standards rule, limiting emissions of hazardous air pollutants from coal- and oil-fired electrical generating units. The rule was published in the Federal Register on February 16, 2012, and became effective on April 16, 2012. A number of parties have filed notices of appeal challenging the rule.

Greenhouse Gas Regulation

In March 2012, the US EPA announced proposed carbon dioxide emissions limits for new power plants. The status of the US EPA's efforts to develop greenhouse gas emissions performance standards for existing plants is unknown.

In June 2012, the U.S. Court of Appeals for the D.C. Circuit dismissed the challenge by industry groups and some states to the Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule, known as the "GHG tailoring rule." In August 2012, states and industry groups challenging the rule filed a petition seeking to have the decision reviewed by the full District of Columbia Circuit.

In July 2012, the US EPA published a final rule maintaining the CO ₂ equivalent emissions thresholds (for purposes of PSD and Title V permitting) originally established in the GHG tailoring rule.

Greenhouse Gas Litigation

In March 2012, the federal district court in Mississippi dismissed, in its entirety, the purported class action complaint filed by private citizens in May 2011, naming a large number of defendants, including SCE, EME and other Edison International subsidiaries, for damages allegedly arising from Hurricane Katrina. In April 2012, the plaintiffs filed an appeal with the Fifth Circuit Court of Appeals. Plaintiffs allege that the defendants' activities resulted in emissions of substantial quantities of greenhouse gases that have contributed to climate change and sea level rise, which in turn are alleged to have increased the destructive force of Hurricane Katrina. The lawsuit alleges causes of action for negligence, public and private nuisance, and trespass, and seeks unspecified compensatory and punitive damages. The claims in this lawsuit are nearly identical to a subset of the claims that were raised against many of the same defendants in a previous lawsuit that was filed in, and dismissed by, the same federal district court where the current case has been filed.

In September 2012, a three-judge panel of the U.S Court of Appeals for the Ninth Circuit affirmed the dismissal of a case brought against Edison International and other defendants, by the Alaskan Native Village of Kivalina. In October 2012, the plaintiffs requested a rehearing by a larger panel of Ninth Circuit judges.

Note 11. Accumulated Other Comprehensive Loss

Edison International's accumulated other comprehensive loss consists of:



(in millions)	Unrealized Loss on Cash Flow Hedges			Pension and PBOP – Net Gain (Loss)			Pension and PBOP – Prior Service Cost			Accumulated Other Comprehensive Loss
Balance at December 31, 2011	$	(34	)	$	(100	)	$	(5	)	$	(139	)
Change for 2012	(38		)	9			—			(29		)
Balance at September 30, 2012	$	(72	)	$	(91	)	$	(5	)	$	(168	)

Included in accumulated other comprehensive loss at September 30, 2012 was $7 million , net of tax, of unrealized gains on commodity-based cash flow hedges, and $79 million , net of tax, of unrealized losses related to interest rate hedges. The maximum period over which a commodity cash flow hedge is designated is through December 31, 2013 .

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 $3 million of unrealized gains on cash flow hedges, net of tax, are expected to be reclassified into earnings during the next 12 months . Management expects that reclassification of net unrealized gains will increase energy revenues recognized at market prices. Actual amounts ultimately reclassified into earnings over the next 12 months could vary materially from this estimated amount as a result of changes in market conditions.

Note 12. Supplemental Cash Flows Information

Accrued capital expenditures at September 30, 2012 and 2011 were $431 million and $393 million , respectively. Accrued capital expenditures will be included as an investing activity in the consolidated statements of cash flow in the period paid.

Note 13. Preferred and Preference Stock of Utility

During the first quarter of 2012, SCE issued 350,000 shares of 6.25% Series E Preference Stock (cumulative, $1,000 liquidation value). The Series E preference shares may not be redeemed prior to February 1, 2022 . After February 1, 2022 , SCE may at its option, redeem the shares, in whole or in part for a price of $1,000 per share plus accrued and unpaid dividends, if any. The shares are not subject to mandatory redemption. The proceeds from the sale of these shares were used to repay commercial paper borrowings and to fund SCE's capital program.

During the second quarter of 2012, SCE issued 190,004 shares of 5.625% Series F Preference Stock (cumulative, $2,500 liquidation value) to SCE Trust I, a special purpose entity formed to issue trust securities as discussed in Note 3. Variable Interest Entities. The Series F Preference Stock may not be redeemed prior to June 15, 2017. After June 15, 2017 , SCE may at its option, redeem the shares, in whole or in part for a price of $2,500 per share plus accrued and unpaid dividends, if any. The shares are not subject to mandatory redemption. The proceeds from the sale of these shares were used to repay commercial paper borrowings, for general corporate purposes and to redeem and retire $75 million of the Series A Preference Stock.

Note 15. Other Investments

Nuclear Decommissioning Trusts

Future decommissioning costs of removal of nuclear assets are expected to be funded from independent decommissioning trusts, which currently receive contributions of approximately $23 million per year through SCE customer rates. Contributions to the decommissioning trusts are reviewed every three years by the CPUC. If additional funds are needed for decommissioning, it is probable that the additional funds will be recoverable through customer rates. 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.

The following table sets forth amortized cost and fair value of the trust investments:



		Amortized Cost				Fair Value

Trust fund earnings (based on specific identification) increase the trust fund balance and the ARO regulatory liability. Proceeds from sales of securities (which are reinvested) were $428 million and $962 million for the three months ended September 30, 2012 and 2011 , respectively, and $1.5 billion and $2.1 billion for the nine months ended September 30, 2012 and 2011 , respectively. Unrealized holding gains, net of losses, were $1.6 billion and $1.3 billion at September 30, 2012 and December 31, 2011 , respectively.

The following table sets forth a summary of changes in the fair value of the trust:

Note 17. Planned Sale of Interest in Four Corners

In November 2010, SCE entered into an agreement to sell its ownership interest in Units 4 and 5 of the Four Corners Generating Station, a coal-fired electric generating facility in New Mexico, to the operator of the facility, Arizona Public Service Company. During 2012, the CPUC and the Arizona Corporation Commission ("ACC") approved the transaction. As part of its sale approval, the ACC stipulated that the sale cannot close earlier than December 1, 2012 which under the adjustment mechanism set forth in the sales agreement would reduce the sale price from $294 million to $279 million . The price is also subject to further adjustments. The closing of the sale is contingent upon the receipt of other specified closing conditions, including APS obtaining a long-term fuel supply agreement for the plant. The sale agreement provides for either party to terminate if it is not completed by December 31, 2012. Any gain on the sale will be for the benefit of SCE's customers and, therefore, will not affect SCE's earnings.

Note 18. Discontinued Operations

On September 21, 2012, Homer City and an affiliate of GECC entered into the Homer City MTA for the divestiture by Homer City of substantially all of its remaining assets and certain specified liabilities. On October 3, 2012, GECC entered into a Plan Support Agreement ("the PSA") with the holders of approximately 76% of the outstanding principal amount of the secured lease obligation bonds issued by Homer City Funding, LLC as part of the original sale-leaseback transaction. Under the PSA, the parties committed to support and implement a reorganization plan of Homer City Funding, LLC and to solicit votes on a prepackaged plan of reorganization under Chapter 11 of the U.S. Bankruptcy Code. On October 5, 2012, GECC commenced the solicitation. Homer City Funding, LLC is an affiliate of GECC and not related to Homer City or any other EME affiliate.

Completion of the Homer City MTA is subject to the satisfaction of a number of closing conditions, including the successful restructuring and reorganization of Homer City Funding, LLC and receipt of the regulatory approvals required for the transfer of the Homer City plant to GECC. If an agreement to modify the terms of the bonds is not approved and consummated or if other closing conditions of the Homer City MTA are not met, Homer City may become the subject of bankruptcy proceedings.

EME recorded an impairment charge of $1.03 billion related to Homer City's long-lived assets during the fourth quarter of 2011. Beginning in the third quarter of 2012, Homer City met the definition of a discontinued operation and was classified separately in Edison International's consolidated financial statements. EME recorded a $113 million charge ( $68 million after tax) to write down assets held for sale to net realizable value during the third quarter of 2012.

Summarized results of discontinued operations are as follows:



	Three months ended September 30,						Nine months ended September 30,
(in millions)	2012			2011			2012			2011

Note 19. EME Liquidity and Restructuring Activities

At September 30, 2012 , EME, and its subsidiaries without contractual dividend restrictions, had corporate cash and cash equivalents of $627 million , which includes Midwest Generation's cash and cash equivalents of $142 million . At September 30, 2012 , EME had $3.7 billion of unsecured notes outstanding, $500 million of which mature in June 2013.

EME continues to experience operating losses due to low realized energy and capacity prices, high fuel costs and low generation at the Midwest Generation plants. Forward market prices indicate that these trends are expected to continue for a number of years. As a result, EME expects that it will incur further reductions in cash flow and losses in the current year and in subsequent years. A continuation of these adverse trends coupled with pending debt maturities and the need to retrofit its Midwest Generation plants to comply with governmental regulations will exhaust EME's liquidity. Consequently, EME has been considering all options available to it, including potential sales of assets, restructuring, reorganization of its capital structure, or conservation of cash that would be applied otherwise to the payment of obligations.

In June 2012, EME entered into non-disclosure and engagement agreements with advisors representing holders of a majority in principal amount of its unsecured bonds for the purpose of engaging in discussions with such advisors and Edison International regarding EME's financial condition. In October 2012, EME and Edison International entered into non-disclosure agreements with certain of the clients of such advisors to facilitate further discussions. Discussions with the bondholders' advisors have been ongoing. In addition, EME and Midwest Generation have entered into a non-disclosure agreement with an advisor representing a majority in principal amount of Midwest Generation's senior lease obligation bonds.

grace period for interest payments. EME's failure to pay indebtedness under its unsecured bonds would likely result in EME's filing for protection under Chapter 11 of the U.S. Bankruptcy Code, which would trigger cross defaults under EME's guarantee of the lease obligations of Midwest Generation, as well as Midwest Generation's own obligations under the lease and under instruments governing the senior lease obligation bonds, and which could potentially give rise to counterparty rights and remedies under other documents.

Under the applicable accounting standards, Edison International would no longer consolidate EME for financial reporting purposes if it filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, as Edison International would no longer have a controlling financial interest for accounting purposes. In order to deconsolidate EME for financial reporting purposes, the carrying values of the assets and liabilities of EME would be removed from Edison International's consolidated balance sheets as of the bankruptcy filing date and the investment in EME would be recorded at its estimated fair value. Any loss would be recognized in an amount equal to the excess of the book value of Edison International's investment in EME over the fair value of such investment. At September 30, 2012 , the book value of Edison International's investment in EME was $1.24 billion . Any amounts recorded as part of accumulated other comprehensive loss related to EME would be recognized as a loss upon deconsolidation. At September 30, 2012, the amount recorded as accumulated other comprehensive loss related to EME was $128 million . In addition, Edison International would record any liabilities due to EME and certain liabilities that are joint and several with EME, including liabilities for uncertain tax positions taken in consolidated or combined tax returns of Edison International that are otherwise not resolved through the tax-allocation agreement and certain retirement plans. Under current regulations, during bankruptcy, EME would continue to be consolidated with Edison International for federal income tax purposes until a change in ownership occurred.

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 (losses) by principal operating subsidiary are also used when communicating with analysts and investors regarding Edison International's earnings results to facilitate comparisons of the Company's performance from period to period. Core earnings (losses) are a non-GAAP financial measure and may not be comparable to those of other companies. Core earnings (losses) are defined as earnings attributable to Edison International shareholders less 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: exit activities, including lease terminations, sale of certain assets, early debt extinguishment costs and other activities that are no longer continuing; asset impairments and certain tax, regulatory or legal settlements or proceedings. EMG classified the results of Homer City, including the costs incurred in connection with the expected divestiture, as non-core for both the three and nine months ended 2012 and 2011 due to the plan described below to transition ownership of the leasehold interest to the owner-lessors.

SCE's 2012 core earnings decreased $43 million and $102 million for the quarter and year-to-date, respectively. Core earnings in both periods decreased primarily due to a delay in the 2012 CPUC General Rate Case decision as higher depreciation and net interest expenses are not being recovered in currently authorized revenue, as well as higher costs at San Onofre. SCE has incurred $48 million and $96 million of incremental steam generator inspection and repair costs related to outages at San Onofre for the quarter and year-to-date periods in 2012, respectively, and $30 million in severance costs. These costs were partially offset by other operations and maintenance cost reductions in both periods. The revenue requirement ultimately adopted by the CPUC will be retroactive to January 1, 2012.

EMG's 2012 core losses increased $110 million and $219 million for the quarter and year-to-date, respectively. The increase in core losses was primarily due to lower average realized energy and capacity prices and lower generation at the Midwest Generation plants, decreased earnings from natural gas-fired projects and lower income tax benefits.

Edison International Parent and Other core losses increased $23 million and $29 million for the quarter and year-to-date, respectively. The increase in core losses was primarily due to higher consolidated state income taxes.

Consolidated non-core items for 2012 and 2011 for Edison International included:

•

$113 million pre-tax charge ($68 million after tax) associated with the divestiture by Homer City of substantially all of its remaining assets and certain specified liabilities. Pursuant to the Homer City MTA, beginning in the third quarter of 2012, Homer City met the definition of a discontinued operation and was classified separately in Edison International's consolidated statement of operations.


•	In August 2012, Edison Capital sold its lease interest in Unit No. 2 of the Beaver Valley Nuclear Power Plant to a third party for $108 million and recorded a pre-tax gain of $65 million ($31 million after tax).

Management Overview of SCE

2012 CPUC General Rate Case

As discussed in the year-ended 2011 MD&A, SCE's 2012 GRC application, which requested a 2012 base rate revenue requirement of $6.29 billion, has been under submission to the CPUC.

On October 19, 2012, the CPUC assigned administrative law judge issued a proposed decision, which, if adopted, would result in a 2012 base rate revenue requirement of $5.69 billion, a decrease of $601 million from SCE's requested revenue requirement, primarily related to decreases in operations and maintenance expenses with some plant-related capital reductions, including potential disallowances of recorded capital investments for specific projects. The proposed decision, if adopted, would result in an increase of approximately $400 million over currently authorized revenue. The proposed decision approves San Onofre costs subject to refund and reasonableness review and includes a requirement to track those costs in a memorandum account. See “—San Onofre” below for further information. The proposed decision also accepts SCE's requested rate-making treatment of tax repair deductions. See "Edison International Notes to Consolidated Financial Statements—Note 7. Income Taxes" for further discussion.

The proposed decision would allow a post-test year ratemaking methodology that escalates capital additions by 3.05% for 2013 and 2.93% for 2014. It would also allow operations and maintenance expense to be escalated for 2013 and 2014 through the use of various escalation factors for labor, non-labor and medical expenses. The methodology adopted in the proposed decision would result in a revenue requirement of $6.08 billion for 2013 and $6.43 billion for 2014.

SCE is currently recognizing revenue largely based on the 2011 authorized revenue requirement. The CPUC has authorized the establishment of a GRC memorandum account, which will make the 2012 revenue requirement ultimately adopted by the CPUC effective as of January 1, 2012.

SCE is required to file comments within 20 days of receiving the proposed decision. The final CPUC decision could result in material changes to the proposed decision. A final CPUC decision is expected by year end.

2013 Cost of Capital Application

In June 2012, the CPUC issued an order in the 2013 Cost of Capital proceeding consolidating SCE's 2013 application with the three other California investor-owned utilities' applications and splitting the proceeding into two phases. The first phase will address the 2013 ratemaking capital structure and cost of capital for the utilities and contemplates a final decision in December 2012. The second phase will consider whether the current multi-year mechanism should be continued or modified. A final decision for the second phase is expected in April 2013.

SCE's 2013 cost of capital application, which was filed in April 2012, requested a ratemaking capital structure of 43% long-term debt, 9% preferred equity and 48% common equity consistent with the current capital structure. In October 2012, SCE submitted an update to its requested cost of capital further reducing its current cost of capital as follows: cost of long-term debt from 6.22% to 5.49%, authorized cost of preferred equity from 6.01% to 5.79% and authorized return on common equity from 11.5% to 11.1%. The application also requested the continuation of the current multi-year mechanism, which would have retained the authorized capital structure through 2015 with annual adjustments of the cost components if certain thresholds are reached.

San Onofre

Outage, Inspection and Repair Issues

As discussed in the 2011 Form 10-K, four replacement steam generators were installed at San Onofre Units 2 and 3 in 2010 and 2011, respectively. In the first quarter of 2012, a water leak suddenly occurred in one of the heat transfer tubes in San Onofre's Unit 3 steam generators. Unit 3 was safely taken off-line. At the time, San Onofre Unit 2 was off-line for a planned outage when areas of unexpected wear in some of its heat transfer tubes were found. Both Units have remained off-line for

extensive inspections, testing and analysis of their steam generators. Each Unit will be restarted only when and if SCE determines that it is safe to do so and when start-up has been approved by the NRC pursuant to the terms of a Confirmatory Action Letter (“CAL”) issued by the NRC in March 2012. The CAL requires NRC permission to restart Unit 2 and Unit 3 and outlines actions SCE must complete before permission to restart either Unit may be sought. In October 2012, SCE submitted to the NRC a response to the CAL and restart plans for Unit 2 as described below.

Tube Leak and Repairs

The water leak in the Unit 3 steam generator was caused by excessive wear resulting from tube-to-tube contact in the area of the leak. During the inspection and testing of the Unit 3 steam generators, additional pressure tests of certain tubes were completed to determine the safety significance of the wear. Eight of the 129 tubes subjected to the additional tests failed the tests for structural integrity as a result of excessive wear, and the NRC was notified as required. The same areas were re-inspected in the Unit 2 steam generators using a more sensitive inspection method than had previously been employed, and similar wear from tube-to-tube contact was found on two tubes in one of the steam generators at wear levels below the detection capability of the initial inspection. Earlier tests performed on the Unit 2 steam generators during the planned outage additionally found levels of unexpected wear at points where some tubes were in contact with retainer bars of the tube support structure. Subsequent inspections on Unit 3 found similar tube-to-support structure wear.

As a result of these findings, SCE has plugged and removed from service all tubes showing excessive wear in each of the steam generators. In addition, SCE preventively plugged all tubes in contact with retainer bars or in the area of the tube bundles where tube-to-tube contact occurred. Each steam generator has over 9,700 heat transfer tubes and is designed to include sufficient tubes to accommodate a need to remove some from service for a variety of reasons, and the tubes that SCE has removed from service are within this margin.

A team of outside experts was assembled to assist SCE and Mitsubishi Heavy Industries, Inc. (“MHI”), the manufacturer of the steam generators, in the analysis of the causes of the tube-to-tube wear and potential remedial actions. As a result of their work, SCE understands that the tube-to-tube contact arises from excessive vibration of the tubes in certain areas of the steam generators. The excessive vibration that caused the tube-to-tube wear on Unit 3 resulted from a phenomenon called fluid elastic instability. This phenomenon arises from a combination of thermal hydraulic conditions (steam velocity and moisture content of the steam), and ineffectiveness of the tube supports in the areas where the vibration occurs. Unit 2 is susceptible to the same thermal hydraulic conditions as Unit 3, but the Unit 2 supports largely remained effective for the entire time that it operated as compared to Unit 3. This difference is likely the result of manufacturing differences between the pairs of steam generators in the two Units.

SCE's restart plans for Unit 2 and its response to the CAL are based on work done by engineering groups of three independent firms with expertise in steam generator design and manufacturing. Restart plans for only Unit 2 were submitted because of the extensive tube-to-tube wear in Unit 3, which was not experienced in Unit 2 (in which only one point of tube-to-tube wear between two tubes was identified). Using different methodologies, each independent outside engineering group concluded that it would be safe to restart Unit 2 and operate at a reduced power level (70%) for approximately five months, followed by a mid-cycle scheduled outage. The power level is being reduced to avoid the steam velocity and moisture content conditions that cause fluid elastic instability. The five month operating period is less than half the time Unit 3 operated and was validated by the independent experts as providing a safety margin to provide assurance of safe operation. In addition to these requirements, the restart plan covers repairs, corrective actions and operating parameters and also includes additional monitoring, detection and response activities.

Inasmuch as Unit 3 had much more tube-to-tube wear than Unit 2, it is not clear at this time whether Unit 3 will be able to restart without extensive additional repairs and corrective actions. Unit 3 will not restart this year and it is uncertain when or whether a restart plan will be submitted. The Unit 3 reactor is de-fueled and SCE is placing appropriate systems in a lay-up condition while analysis and testing continue. SCE is also engaged in the analysis of what repairs, if any, could be undertaken to restore the steam generators on both Units to their originally specified capabilities safely, but it has not determined what those repairs might be or whether the generators will need to be replaced for the Units to operate at their prior output levels. Each Unit will only be restarted when any necessary repairs and appropriate mitigation plans for that Unit are completed in accordance with the CAL, and the NRC and SCE are satisfied that it is safe to do so.

NRC Processes

The timing of restart of the Units will also be affected by the nature of and schedule for regulatory processes required by the NRC. There is no set or predetermined time period for approval of Unit 2's proposed restart, and, accordingly, there can be no assurance about the length of time the NRC may take to review SCE's request to restart or whether any such request would be granted in whole or in part.

The NRC will conduct one or more on-site inspections to verify that SCE has performed the actions described in the CAL response and will hold public meetings to discuss the CAL response as well as the results of the on-site inspections. There is no timeline for the NRC's review of the CAL response. It is also possible that one or more amendments to the NRC operating license for San Onofre might be required (whether or not as a prerequisite to return a Unit to safe operation). The NRC could also choose to impose additional processes and assessments that could result in significant costs or additional delay.

Following the failure of pressure tests on the eight tubes in Unit 3, the NRC launched an Augmented Inspection Team (“AIT”) to assess the tube failures and their causes, SCE's operation of the Units, and SCE's oversight of the design, fabrication, shipping, and construction process. In July 2012, the NRC issued a report providing the results of the AIT inspection. That report concluded that the replacement steam generators' design and configuration did not provide the necessary margin to prevent fluid elastic instability and that these deficiencies appear to be related to MHI's computer code used to model thermal hydraulic conditions in the steam generators. The report further stated that SCE was adequately pursuing the causes of the unexpected steam generator tube-to-tube degradation. The AIT report also identified a number of as-yet unresolved issues that are continuing to be examined. The unresolved issues include further evaluation of manufacturing differences between Unit 2 and Unit 3, with particular focus on the control of critical dimensions affecting the clearances between tubes and tube supports. The NRC will conduct subsequent inspections or reviews to determine what, if any, regulatory actions result from these unresolved items. Should the NRC find a deficiency in SCE's performance, SCE could be subject to additional NRC actions, and the findings could be taken into consideration in the CPUC regulatory proceedings described below.

CPUC Review

In October 2012, in advance of SCE's required notification under Section 455.5, the CPUC issued an order instituting investigation that will consolidate all San Onofre issues in related regulatory proceedings and consider appropriate cost recovery for all San Onofre costs, including among other costs, the cost of the steam generator replacement project, market power costs, capital and operations and maintenance costs, and seismic study costs. The order requires that all San Onofre-related costs incurred on and after January 1, 2012 be tracked in a memorandum account and, to the extent included in rates, collected subject to refund. The order also states that the CPUC will determine whether to order the immediate removal, effective as of the date of the order, of all costs related to San Onofre from SCE's rates, with placement of those costs in a deferred debit account pending the return of one or both Units to useful service, or other possible action. SCE will file its response to the order by November 26, 2012. SCE must also file testimony by December 10, 2012 detailing proposed rate adjustments due to the outages, including the amount of San Onofre costs in current rates, the amount to be removed, if any, the effective date, and related information. A pre-hearing conference will be scheduled early in 2013 after the issuance of a Scoping Memo by the Assigned Commissioner.

In parallel with the order instituting investigation, the 2012 GRC proposed decision would, if adopted, require SCE to track San Onofre-related costs in a memorandum account subject to refund, beginning January 1, 2012. SCE would be required by January 30, 2013 to file an application for reasonableness review of these costs and the proposed decision would allow that application to be consolidated with other proceedings. The 2012 GRC proposed decision also approves expenditures incurred through 2011 for the high pressure turbine project, but disallows recovery for post-2011 expenditures associated with the project and directs SCE to record those costs in either the memorandum account or seek future rate recovery in the next GRC. SCE anticipates that the inter-relationship between the Section 455.5 process and the issues to be reviewed in the investigation or pursuant to a final decision in the GRC will be addressed by the CPUC as it continues to develop the scope of the issues to be consolidated within the investigation.

In addition to the amounts for inspection and repair and market power costs discussed below, SCE has collected through customer rates an estimated $625 million of revenue through third quarter 2012 (based on current authorized revenue requirements) associated with the plant. SCE's total 2012 San Onofre annual revenue requirement, including the 2012 GRC proposed decision, is approximately $820 million, made up of $170 million in refueling outage, nuclear fuel and decommissioning costs and $650 million for its direct operating and maintenance costs, depreciation and return on its

investment in San Onofre Unit 2, Unit 3 and related common plant. At September 30, 2012, SCE's rate base and net investment associated with San Onofre were as set forth in the following table:



(in millions)	Unit 2			Unit 3			Common Plant			Total
Net investment
Net plant in service	$	593		$	418		$	261		$	1,272
Materials and supplies	—			—			99			99
Construction work in progress	77			141			76			294

Accumulated deferred income taxes	(95		)	(45		)	(66		)	(206		)
Amounts in rate base	$	498		$	373		$	294		$	1,165

In 2005, the CPUC authorized expenditures of approximately $525 million ($665 million after adjustment for inflation) for SCE's 78.21% share of San Onofre to purchase and install the four new steam generators in Units 2 and 3 and remove and dispose of their predecessors. SCE has spent $594 million through September 30, 2012 on the steam generator replacement project, including $95 million reflected in construction work in progress primarily related to the disposal of the replaced steam generators. Those expenditures remain subject to CPUC reasonableness review. Final costs for the project will not be known until after disposal of the original steam generators is completed.

As a result of outages associated with the steam generator inspection and repair, electric power and capacity normally provided by San Onofre are being purchased in the market by SCE (commencing on February 1 for Unit 3 and March 5 for Unit 2). Market costs through September 30, 2012 were approximately $221 million, net of avoided nuclear fuel costs, and are recoverable through the ERRA balancing account subject to CPUC reasonableness review. Because of the uncertainties associated with when and at what output levels the Units will or may be returned to service, total potential market power costs cannot be estimated at this time.

Contractual Matters

San Onofre carries both property damage and outage insurance issued by Nuclear Electric Insurance Limited (“NEIL”) and has placed NEIL on notice of potential claims for loss recovery. The property damage policy (including excess coverage) provides insurance for certain costs and expenses resulting from “Accidental Property Damage” with a $2.5 million deductible and a $2.75 billion limit of liability. After a twelve week deductible period, the outage policy provides insurance for an outage caused by “Accidental Property Damage” of up to $3.5 million per week for each Unit (or $2.8 million per Unit per week if both Units are out because of the same "Accident"), with a $490 million limit for each Unit ($392 million each if both Units are out because of the same "Accident"). The NEIL policies have a number of exclusions and limitations that may

reduce or eliminate coverage. For instance, coverage may be reduced or excluded if it is determined that the outage resulted from any condition which develops, progresses or changes over time, or from wear and tear. Further, costs to "make good" faulty workmanship or design and amounts collectible from third parties are excluded from the property damage policy. Proof of loss must be submitted within 12 months of the Accidental Property Damage under the property damage insurance and within 12 months of the end of the outage under the outage policy. In October 2012, SCE filed separate proofs of loss for Unit 2 and Unit 3 under the outage policy. Pursuant to these proofs of loss SCE is seeking the weekly indemnity amounts provided under the policy for each Unit. Because the outage is ongoing, SCE will supplement these proofs of loss in the future. No amounts have been recognized in SCE's financial statements, pending further actions by NEIL. To the extent any costs are recovered under the outage policy, SCE expects to refund those amounts to ratepayers through the ERRA balancing account. For further information, see "Edison International Notes to Consolidated Financial Statements—Note 9. Commitments and Contingencies."

SCE will pursue recoveries arising from available agreements, but there is no assurance that SCE will recover all of its applicable costs pursuant to these arrangements.

CAISO Summer Readiness Planning

In addition to providing up to 2,200 MW of electric power, San Onofre also provides significant reliability support to the electric grid, including support for grid voltage and stability. SCE continues to work with the CAISO to maintain grid reliability for summer 2013 and beyond while the San Onofre Units are out of service. SCE is supporting CAISO in its negotiations to obtain local grid voltage support. SCE has also accelerated certain transmission projects and will expand its demand response programs to help maintain grid reliability. The majority of these efforts are projects that are already included in SCE's capital expenditure plan, but their timing has been accelerated. In addition, SCE has proposed to the CAISO projects such as transmission line reconfiguration and installation of equipment to support voltage and stability. The projects, if approved could result in additional capital expenditures from $100 million to $125 million over the period 2013 – 2015.

Workforce Reduction

Capital Program

During the first nine months of 2012, SCE's capital investment program focused on maintaining reliability and expanding the capability of SCE's transmission and distribution system; upgrading and constructing new transmission lines and substations; installing digital meters; and replacing generation asset equipment. Total capital expenditures (including accruals) were $2.6 billion during the first nine months of 2012 compared to $2.5 billion during the same period in 2011. SCE expects that 2012 capital expenditures will be below the lower end of the previously projected $4.4 billion to $5.0 billion range due to the delay in the GRC decision, the delay related to the Tehachapi Project and outages at San Onofre. However, SCE continues to project that 2012 – 2014 total capital expenditures will be in the range of $11.8 billion to $13.2 billion. Actual capital spending will be affected by: changes in regulatory, environmental and engineering design requirements; permitting and project delays; cost and availability of labor, equipment and materials; outcome of the San Onofre mitigation plans; and other factors.

Management Overview of EMG

EME Liquidity and Restructuring Activities

EME's operating loss increased significantly in the nine months ended September 30, 2012 compared to the same period in 2011, primarily due to lower capacity and average realized energy prices, reduced generation and higher fuel prices at the Midwest Generation plants. The abundance of low-priced natural gas has continued to result in increased competition from natural gas-fired generating units in the markets in which Midwest Generation operates, and generation has been correspondingly affected. In addition, effective January 1, 2012, a favorable long-term rail contract that supplied Midwest Generation's fleet expired and was replaced by a higher priced contract.

At September 30, 2012, EME, and its subsidiaries without contractual dividend restrictions, had corporate cash and cash equivalents of $627 million, which includes Midwest Generation's cash and cash equivalents of $142 million. At September 30, 2012, EME had $3.7 billion of unsecured notes outstanding, $500 million of which mature in June 2013.

Based on current projections, EME is not expected to have sufficient liquidity to repay the $500 million debt obligation due in June 2013. On November 15, 2012, $97 million of interest payments are due on unsecured EME bonds maturing in 2017, 2019 and 2027, and there is no assurance payment will be made. EME's unsecured bonds generally provide for a 30-day grace period for interest payments. EME's failure to pay indebtedness under its unsecured bonds will likely result in EME's filing for protection under Chapter 11 of the U.S. Bankruptcy Code, which would trigger cross defaults under EME's guarantee of the lease obligations of Midwest Generation, as well as Midwest Generation's own obligations under the lease and under instruments governing the senior lease obligation bonds, and which could potentially give rise to counterparty rights and remedies under other documents.

Bankruptcy proceedings could lead to a change of control of EME, which would, among other things, result in the termination of EME's tax-allocation agreement. At September 30, 2012, EME had recognized $635 million of net tax benefits based on continued ownership by Edison International and inclusion of EME in the consolidated income tax returns of Edison International and its subsidiaries. If realization is unlikely, EME would record a valuation allowance to reduce the carrying value of these assets and record a material charge against earnings. The termination of the tax-allocation agreement could adversely affect EME's long-term liquidity because realization of the value of tax benefits generated by EME could be deferred until such time that EME, or a subsequent owner of EME, had the ability to utilize such benefits. There is no assurance as to when, or whether, this might occur.

Under the applicable accounting standards, Edison International would no longer consolidate EME for financial reporting purposes if it filed for bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, as Edison International would no longer have a controlling financial interest for accounting purposes. In order to deconsolidate EME for financial reporting purposes, the carrying values of the assets and liabilities of EME would be removed from Edison International's consolidated balance sheets as of the bankruptcy filing date and the investment in EME would be recorded at its estimated fair value. Any loss would be recognized in an amount equal to the excess of the book value of Edison International's investment in EME over the fair value of such investment. At September 30, 2012, the book value of Edison International's investment in EME was $1.24 billion. Any amounts recorded as part of accumulated other comprehensive loss related to EME would be recognized as a loss upon deconsolidation. At September 30, 2012, the amount recorded as accumulated other comprehensive loss related to EME was $128 million. In addition, Edison International would record any liabilities due to EME and certain liabilities that are joint and several with EME, including liabilities for uncertain tax positions taken in consolidated or combined tax returns of Edison International that are otherwise not resolved through the tax-allocation agreement and certain retirement plans. Under current regulations, during bankruptcy, EME would continue to be consolidated with Edison International for federal income tax purposes until a change in ownership occurred.

The accompanying consolidated financial statements have been prepared assuming that EME will continue as a going concern. Financial statements prepared on this basis assume the realization of assets and the satisfaction of liabilities in the normal course of business for the 12-month period following the date of these financial statements. There is no assurance that EME will be able to continue as a going concern.

Midwest Generation's Dependence on EME

Midwest Generation is largely dependent on EME to fund cash flow deficits and environmental retrofits. EME has no obligation to make capital contributions to Midwest Generation and may be unable to do so. Furthermore, Midwest Generation had $1.323 billion of notes receivable from EME at September 30, 2012 with payments used to meet its rent obligations under the Powerton and Joliet sale-leaseback agreements. If EME is unable to make payments on its notes,

Midwest Generation may in turn be unable to make rent payments under the Powerton-Joliet leases. Failure to pay rent would be an event of default under the Powerton-Joliet leases that could result in termination of the leases, loss of control over the use of the Powerton and Joliet Stations and a claim for termination value under the lease agreements. Accordingly, if Midwest Generation is unable to obtain financial support from EME or other sources, Midwest Generation may need to file for protection under Chapter 11 of the U.S. Bankruptcy Code. A bankruptcy of either EME or Midwest Generation would also be an event of default under the Powerton-Joliet leases.

Midwest Generation Environmental Compliance Plans and Costs

During the third quarter of 2012, Midwest Generation continued to develop and implement a compliance program that includes the operation of ACI systems for mercury removal, upgrades to particulate removal systems and the use of dry sorbent injection, combined with the use of low sulfur PRB coal, to meet emissions limits for criteria pollutants, such as NO _x and SO ₂ as well as for hazardous air pollutants, such as mercury, acid gas and non-mercury metals.

Apart from the Fisk and Crawford Stations, which ceased operations in September 2012, decisions whether or not to proceed with retrofitting of any particular remaining units to comply with CPS requirements for SO ₂ emissions, including those that have received permits, are subject to a number of factors, such as market conditions, regulatory and legislative developments, liquidity and forecasted commodity prices and capital and operating costs applicable at the time decisions are required or made. Midwest Generation may also elect to shut down units, instead of installing controls, to be in compliance with the CPS. Final decisions on whether to install controls, to install particular kinds of controls, and to actually expend capital or continue with the expenditure of capital will be made as required, subject to the requirements of the CPS and other applicable regulations. Units that are not retrofitted may continue to operate for as long as regulations and law allow.

Based on work to date, Midwest Generation estimates the remaining cost of retrofitting Powerton Units 5 and 6, Joliet Units 7 and 8 and Will County Units 3 and 4, using dry scrubbing with sodium-based sorbents and upgrading particulate removal systems, to be approximately $619 million at September 30, 2012. It is less likely that retrofits will be made to Joliet Unit 6 and the Waukegan Station. During the third quarter of 2012, the Pollution Control Board granted Midwest Generation's request to extend Waukegan Unit 7's unit specific retrofit requirements from December 31, 2013 to December 31, 2014. The estimated cost of retrofitting Joliet Unit 6, if made, would be approximately $75 million, while the estimated cost of retrofitting the Waukegan Station, if made, would be approximately $160 million. Final decisions to shut down units will be made in light of the timing requirements under the CPS and other applicable environmental regulations, based on the economic projections of those retrofits, on a unit-by-unit basis, at the time the decision is made. For further discussion related to the impairment policy on Midwest Generation's unit of account, refer to "Critical Accounting Estimates and Policies—Impairment of Long-Lived Assets" in the year-ended 2011 MD&A.

Homer City Lease

On September 21, 2012, Homer City and an affiliate of GECC entered into the Homer City MTA for the divestiture by Homer City of substantially all of its remaining assets and certain specified liabilities. On October 3, 2012, GECC entered into a Plan Support Agreement (the PSA) with the holders of approximately 76% of the outstanding principal amount of the secured lease obligation bonds issued by Homer City Funding, LLC as part of the original sale-leaseback transaction. Under the PSA, the parties committed to support and implement a reorganization plan of Homer City Funding, LLC and to solicit votes on a prepackaged plan of reorganization under Chapter 11 of the U.S. Bankruptcy Code. On October 5, 2012, GECC commenced the solicitation. Homer City Funding, LLC is an affiliate of GECC and not related to Homer City or any other EME affiliate. In addition, Homer City received a forbearance of the $47 million senior rent payment that had been due October 1, 2012 and was granted a waiver of the $65 million equity rent payment that had been due April 1, 2012.

Beginning in the third quarter of 2012, Homer City met the definition of a discontinued operation and EME recorded a $113 million charge ($68 million after tax) to write down assets held for sale to net realizable value during the third quarter of 2012.

SOUTHERN CALIFORNIA EDISON COMPANY

RESULTS OF OPERATIONS

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

•

Utility earning activities – representing revenue authorized by the CPUC and FERC which is intended to provide SCE a reasonable opportunity to recover its costs and earn a return on its net investment in generation, transmission and distribution assets. The annual revenue requirements are comprised of authorized operation and maintenance costs, depreciation, taxes and a return consistent with the capital structure. Also, included in utility earnings activities are revenues or penalties related to incentive mechanisms, other operating revenue, and regulatory charges or disallowances, if any.


•	Utility cost-recovery activities – representing CPUC- and FERC-authorized balancing accounts which allow for recovery of specific project or program costs, subject to reasonableness review or compliance with upfront standards.

The following tables summarize SCE's results of operations for the periods indicated. The presentation below separately identifies utility earning activities and utility cost-recovery activities. Beginning in 2012, SCE classified revenues and costs related to programs that provide for recovery of actual costs plus a return on capital as utility earning activities. Previously, SCE classified the recovery of actual costs incurred under these programs as utility cost-recovery activities. The tables presented below reflect a reclassification of the revenues and costs for 2011 consistent with the presentation in 2012. The reclassification of revenues and costs had no impact on earnings.

During the first nine months of 2012 , pending the outcome of the 2012 GRC, SCE recognized GRC-related revenue based on the 2011 authorized revenue requirement included in customer rates. This has resulted in a decrease in net income as higher depreciation and net interest expenses are not being recovered in currently authorized revenue. A GRC memorandum account has been established for SCE, which will make the 2012 revenue requirement ultimately adopted by the CPUC effective as of January 1, 2012. Recognition of the revenue for the period January 1, 2012 through the date of a final decision, as well as any delays in certain expenditures and changes in authorized treatment of specific costs, will impact the timing of earnings in 2012 (see "Edison International Overview—Management Overview of SCE—2012 CPUC General Rate Case" for further discussion).

Utility Earning Activities

Utility earning activities were primarily affected by the following:

•

Higher operations and maintenance expense of $57 million was primarily due to increased costs at San Onofre, including $48 million related to the steam generator inspection and repair at San Onofre and $30 million of estimated cash severance costs related to the planned San Onofre reduction in workforce; partially offset by lower operations and maintenance expenses. These increases were partially offset by EdisonSmartConnect ^® benefits realized and other cost savings and timing of expenses.


•	Higher depreciation, decommissioning and amortization expense of $41 million was primarily related to increased generation, transmission and distribution investments, including capitalized software costs.


•	Lower income taxes due to lower pre-tax income. See "—Income Taxes" below for more information.


•	Higher preferred and preference stock dividends of $10 million related to new issuances in 2012.

Utility Cost-Recovery Activities

Utility cost-recovery activities were primarily affected by the following:

•

Higher fuel and purchased power expense of $320 million was primarily driven by the cost to replace CDWR contracts that expired in 2011, which were not previously recorded as an SCE cost but which were included as a separate component on customer bills (see "—Supplemental Operating Revenue Information" below) and $104 million of market costs net of lower nuclear fuel costs related to the outage at San Onofre in 2012 (see "Edison International Overview—Management Overview of SCE—San Onofre" for further information). These increases were partially offset by lower power prices in 2012.


•	Higher operations and maintenance expense of $30 million was primarily due to increased energy efficiency program costs.

Utility Earning Activities

Utility earning activities were primarily affected by the following:

•

Higher operating revenue of $74 million was primarily due to $80 million of increased revenue related to authorized CPUC projects not included in SCE's GRC process, including the EdisonSmartConnect ^® project and the Solar Photovoltaic project (approximately $65 million primarily recovered operations and maintenance and depreciation expense associated with the related CPUC projects). The change in revenue also reflects revenue recognized in 2012 related to the San Onofre Unit 2 scheduled outage costs. In December 2011, the CPUC authorized revenue requirements for 2012 refueling outages for San Onofre. These increases were partially offset by decreases in other operating revenue.

•

Higher operation and maintenance expense of $99 million was primarily due to increased costs at San Onofre, including $96 million of costs related to the steam generator inspection and repair as well as $35 million related to the 2012 San Onofre Unit 2 scheduled maintenance and refueling outage and $30 million of estimated cash severance costs related to the planned San Onofre reduction in workforce (see "Edison International Overview—Management Overview of SCE—San Onofre" for further information); partially offset by lower operations and maintenance expenses. These increases were partially offset by EdisonSmartConnect ^® benefits realized and other cost savings and timing of expenses.


•	Higher depreciation, decommissioning and amortization expense of $129 million was primarily related to increased generation, transmission and distribution investments, including capitalized software costs and CPUC capital-related projects discussed above.


•	Higher net interest expense and other of $27 million was primarily due to higher outstanding balances on long-term debt.


•	Lower income taxes due to lower pre-tax income. See "—Income Taxes" below for more information.


•	Higher preferred and preference stock dividends of $22 million related to new issuances in 2012.

Utility Cost-Recovery Activities

Utility cost-recovery activities were primarily affected by the following:

•

Higher fuel and purchased power expense of $578 million was primarily driven by the cost to replace CDWR contracts that expired in 2011, which were not previously recorded as an SCE cost but which were included as a separate component on customer bills (see "—Supplemental Operating Revenue Information" below) and $221 million of market costs net of lower nuclear fuel costs related to the San Onofre outage in 2012 (see "Edison International Overview—Management Overview of SCE—San Onofre" for further information). These increases were partially offset by lower power prices in 2012.


•	Higher operation and maintenance expense of $73 million was primarily due to increased pension contributions.

Supplemental Operating Revenue Information

SCE's retail billed and unbilled revenue (excluding wholesale sales and balancing account over/undercollections) was $3.7 billion and $8.7 billion for the three- and nine-month periods ended September 30, 2012 , respectively, compared to $3.3 billion and $7.8 billion for the respective periods in 2011 . The increase in revenue reflects:

•

A sales volume increase of $677 million and $1.4 billion for the three- and nine-month periods, respectively, primarily due to SCE providing power that was previously provided by CDWR contracts which expired in 2011. Prior to 2012, SCE remitted to CDWR and did not recognize as revenue the amounts that SCE billed and collected from its customers for the portion of electric power purchased and sold by the CDWR to SCE's customers.


•	A rate decrease of $294 million and $502 million for the three- and nine-month periods, respectively, resulting from rate adjustments in June 2011 and August 2012, primarily reflecting lower forecasted fuel and purchased power costs and refunds to customers of overcollected fuel and power procurement-related costs.

As a result of the CPUC-authorized decoupling mechanism, SCE earnings are not affected by changes in retail electricity sales (see "Item 1. Business—Overview of Ratemaking Process" in the 2011 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.

Income Taxes

The table below provides a reconciliation of income tax expense computed at the federal statutory income tax rate to the income tax provision.



	Three months ended September 30,						Nine months ended September 30,
(in millions)	2012			2011			2012			2011
Income before income taxes	$	564		$	666		$	1,186		$	1,378
Provision for income tax at federal statutory rate of 35%	197			233			415			482

Total income tax expense	$	176		$	245		$	384		$	496
Effective tax rate	31		%	37		%	32		%	36		%

State income taxes were lower for both the three- and nine-month periods ended September 30, 2012 due to lower pre-tax income and higher benefits related to depreciation, cost of removal and repair deductions, including additional tax deductions reflected in SCE's 2011 tax returns.

For a discussion of the status of Edison International's income tax audits, see "Edison International Notes to Consolidated Financial Statements—Note 7. Income Taxes."

LIQUIDITY AND CAPITAL RESOURCES

SCE's ability to operate its business, fund capital expenditures, and implement its business strategy are dependent upon its cash flow and access to the capital markets. SCE's overall cash flows fluctuate based on, among other things, its ability to recover its costs in a timely manner from its customers through regulated rates, changes in commodity prices and volumes, collateral requirements, interest and dividend payments to investors, and the outcome of tax and regulatory matters.

SCE expects to fund its 2012 obligations, capital expenditures and dividends through operating cash flows and capital market financings of debt and preferred equity, as needed. SCE also has availability under its credit facilities to meet operating and capital requirements.

Available Liquidity

During the second quarter of 2012, SCE replaced its existing credit facilities scheduled to mature in early 2013 with a new $2.75 billion five-year revolving credit facility that matures May 2017. The following table summarizes the status of the SCE credit facility at September 30, 2012:



(in millions)	Credit Facilities
Commitment	$	2,750
Outstanding commercial paper supported by credit facilities	(380		)
Outstanding letters of credit	(196		)
Amount available	$	2,174

Debt Covenant

SCE has a debt covenant in its credit facility that limits its debt to total capitalization ratio to less than or equal to 0.65 to 1. At September 30, 2012 , SCE's debt to total capitalization ratio was 0.46 to 1.

Capital Investment Plan

Transmission Projects - Tehachapi Project

As discussed in the year-ended 2011 MD&A, the CPUC requested that SCE provide information on potential new options for a portion of the Tehachapi Project, including traversing a state park, changing the nature of some of the towers and undergrounding lines. In July 2012, the Assigned Commissioner issued a ruling requesting SCE to further study and provide more detailed information by the end of February 2013 on two identified undergrounding options for a portion of the project. The ruling set forth a schedule for interested parties to also provide further information, briefing by all parties and evidentiary hearings. The order states that the construction of the affected portion of the project shall remain deferred until the CPUC makes a final determination regarding the options. Adoption of either of the two undergrounding options could create significant additional costs and delay the completion of the project. SCE is required to file revised cost estimates with the CPUC by the end of February 2013. As with all transmission investments, cost recovery will be subject to future rate proceedings.

Regulatory Proceedings

FERC Formula Rates

As discussed in the year-ended 2011 MD&A, the FERC has accepted, subject to refund and settlement procedures, SCE's request to implement formula rates as a means to determine SCE's FERC transmission revenue requirement effective January 1, 2012. SCE's request would result in a total 2012 FERC weighted average ROE of 11.1% including a base ROE of 9.93% and the previously authorized 50 basis point incentive for CAISO participation and individual authorized project incentives.

In September 2012, SCE filed its proposed formula rate update with the FERC. SCE's proposed request would implement a 2013 transmission revenue requirement of $900 million, representing an increase of $178 million or 25% over the 2012 revenue requirement. The increase is primarily due to higher FERC rate base from transmission investments, including projects under construction. Consistent with SCE's proposed formula rate methodology, the proposed revenue requirement utilizes the 2012 FERC authorized base ROE discussed above, which remains subject to refund and the ongoing settlement negotiations.

The formula rate mechanism, including the base ROE, is subject to final resolution as part of the settlement process or, if a settlement is not achieved, to determination by FERC in a litigated process. SCE and the other parties to the proceeding continue to engage in settlement negotiations.

Dividend Restrictions

The CPUC regulates SCE's capital structure which 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 September 30, 2012 , SCE's 13-month weighted-average common equity component of total capitalization was 48.9% resulting in the capacity to pay $175 million in additional dividends to Edison International. During the first nine months of 2012, SCE made $349 million in dividend payments to its parent, Edison International.

Margin and Collateral Deposits

Certain derivative instruments, power procurement contracts and other contractual arrangements contain collateral requirements. Future collateral requirements may differ from the requirements at September 30, 2012 , due to the addition of incremental power and energy procurement contracts with collateral requirements, if any, and the impact of changes in wholesale power and natural gas prices on SCE's contractual obligations.

Some of the power procurement contracts contain provisions that require SCE to maintain an investment grade credit rating from the major credit rating agencies. If SCE's credit rating were to fall below investment grade, SCE may be required to pay the liability or post additional collateral.

The table below provides the amount of collateral posted by SCE to its counterparties as well as the potential collateral that would be required as of September 30, 2012 .

Historical Segment Cash Flows

The table below sets forth condensed historical cash flow information for SCE.



	Nine months ended September 30,
(in millions)	2012			2011
Net cash provided by operating activities	$	2,656		$	2,272
Net cash provided by financing activities	636			672
Net cash used by investing activities	(3,259		)	(3,136		)
Net increase (decrease) in cash and cash equivalents	$	33		$	(192	)

Net Cash Provided by Operating Activities

Net cash provided by operating activities increased $384 million in the first nine months of 2012 compared to the same period in 2011 . The increase in cash flows provided by operating activities was primarily due to higher net tax receipts in 2012 , the impact of higher costs at San Onofre and the timing of cash receipts and disbursements related to working capital items.

Net Cash Provided by Financing Activities

The following table summarizes cash provided by financing activities for the nine months ended September 30, 2012 and 2011 . Issuances of debt and preference stock are discussed in "Edison International Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements—Long-Term Debt" and "Note 12. Preferred and Preference Stock."



	Nine months ended September 30,
(in millions)	2012			2011

Net cash provided by financing activities	$	636		$	672


¹	Issuances of commercial paper are supported by SCE's credit facility.

The timing and amount of SCE's financing activities are largely driven by its capital program.

Net Cash Used by Investing Activities

Cash flows from investing activities are primarily due to capital expenditures and funding of nuclear decommissioning trusts. Capital expenditures were $3.1 billion and $3.0 billion for the nine months ended September 30, 2012 and 2011 , respectively (see "Liquidity and Capital Resources—Capital Investment Plan" in the year-ended 2011 MD&A for further information on capital expenditures). Net purchases of nuclear decommissioning trust investments and other were $164 million and $146 million for the nine months ended September 30, 2012 and 2011 , respectively.

Contractual Obligations and Contingencies

Contractual Obligations

SCE has power purchase commitments which are discussed in "Edison International Notes to Consolidated Financial Statements—Note 9. Commitments and Contingencies."

Contingencies

SCE has contingencies related to the San Onofre Outage, Inspection and Repair Issues, CPSD Investigations, Four Corners New Source Review Litigation, Nuclear Insurance, Wildfire Insurance and Spent Nuclear Fuel, which are discussed in "Edison International Notes to Consolidated Financial Statements—Note 9. Commitments and Contingencies."

Environmental Remediation

As of September 30, 2012, SCE had identified 25 material sites for remediation and recorded an estimated minimum liability of $ 113 million . SCE expects to recover 90% of its remediation costs at certain sites. See "Edison International Notes to Consolidated Financial Statements—Note 9. Commitments and Contingencies" for further discussion.

MARKET RISK EXPOSURES

SCE's primary market risks include fluctuations in interest rates, commodity prices and volumes, and counterparty credit. Fluctuations in interest rates can affect earnings and cash flows. Fluctuations in commodity prices and volumes and counterparty credit losses may temporarily affect cash flows, but are not expected to affect earnings due to expected recovery through regulatory mechanisms. Derivative instruments are used, as appropriate, to manage market risks for customers and SCE. For a further discussion of SCE's market risk exposures, including commodity price risk, credit risk and interest rate risk, see "Edison International Notes to Consolidated Financial Statements—Note 6. Derivative Instruments and Hedging Activities" and " —N ote 4. Fair Value Measurements."

Commodity Price Risk

The fair value of outstanding derivative instruments used to mitigate SCE's exposure to commodity price risk was a net liability of $1.0 billion and $936 million at September 30, 2012 and December 31, 2011, respectively. To the extent San Onofre Unit 2 and Unit 3 are not operating, SCE may be exposed to market prices associated with replacement power costs. SCE's hedging program has taken this exposure into consideration and has entered into forward contracts to address projected market price variability. For further discussion of fair value measurements and the fair value hierarchy, see "Edison International Notes to Consolidated Financial Statements —

Note 4. Fair Value Measurements."

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. SCE manages the credit risk on the portfolio for both rated and non-rated counterparties based on credit ratings using published ratings of counterparties and other publicly disclosed information, such as financial statements, regulatory filings, and press releases, to guide it in the process of setting credit levels, risk limits and contractual arrangements, including master netting agreements. As of September 30, 2012, the amount of balance sheet exposure as described above broken down by the credit ratings of SCE's counterparties, was as follows:



	September 30, 2012
(in millions)	Exposure ²		Collateral			Net Exposure
S&P Credit Rating ¹
A or higher	$	101	$	—		$	101
Not rated ³	5		(1		)	4
Total	$	106	$	(1	)	$	105


¹	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 purchases and sales and non-derivative contractual commitments that are not recorded on the consolidated balance sheets, except for any related net accounts receivable.


³	The exposure in this category relates to long-term power purchase agreements. SCE's exposure is mitigated by regulatory treatment.

EDISON MISSION GROUP

RESULTS OF OPERATIONS

EMG primarily operates in one line of business, independent power production, through the subsidiaries of EMG's principal subsidiary, EME. The following table is a summary of competitive power generation results of operations for the periods indicated.

¹	See use of Non-GAAP financial measures in "Edison International Overview—Highlights of Operating Results."

EMG had a core loss in the third quarter of 2012 compared to core earnings in the third quarter of 2011 primarily due to the following pre-tax items:


•	$117 million decrease in Midwest Generation results primarily due to lower capacity and average realized energy prices, reduced generation and higher fuel prices, partially offset by lower planned maintenance costs and lower depreciation.


•	$29 million decrease in the Sunrise project results due to the transition off of a long-term power purchase agreement to merchant operations.


•	$7 million decrease in renewable energy income primarily attributable to income allocated to third-party investors in Capistrano Wind Partners, partially offset by results of operations from projects that achieved commercial operations after the third quarter of 2011.

The third quarter core loss was partially offset by the following pre-tax item:


•	$10 million increase in energy trading due to higher revenues from trading power and MISO congestion contracts.

EMG's core loss for the nine months ended September 30, 2012 increased compared to the nine months ended September 30, 2011 primarily due to the following pre-tax items:


•	$257 million decrease in Midwest Generation results primarily due to lower capacity and average realized energy prices, reduced generation and higher fuel prices, partially offset by lower planned maintenance costs and lower depreciation.


•	$19 million decrease in the Sunrise project results due to the transition off of a long-term power purchase agreement to merchant operations.


•	$15 million lower income from distributions received from the Doga project.


•	$10 million increase in interest expense primarily due to new project financings.


•	$7 million decrease in renewable energy income was attributable to income allocated to Capistrano Wind Partners, partially offset by results of operations from projects that achieved commercial operations after the third quarter of 2011.

EMG's non-core items for the nine months ended September 30, 2012 included:


•	$113 million pre-tax charge ($68 million after tax) associated with the divestiture by Homer City of substantially all of its remaining assets and certain specified liabilities. Pursuant to the Homer City MTA, beginning in the third quarter of 2012, Homer City met the definition of a discontinued operation and was classified separately in Edison International's consolidated statements of income.


•	$65 million pre-tax gain ($31 million after tax) associated with the Edison Capital's sale of its lease interest in Unit No. 2 of the Beaver Valley Nuclear Power Plant.

Adjusted Operating Income (Loss) ("AOI")—Overview

The following table shows the adjusted operating income (loss) (AOI) of EMG's projects:

AOI ¹	$	17		$	96		$	(73	)	$	169

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

The following table reconciles AOI to operating income (loss) as reflected on EMG's consolidated statements of operations:

Statistics
Generation (in GWh)	6,653			7,957		17,459			20,987

AOI from the Midwest Generation plants decreased $117 million for the third quarter of 2012 and $257 million for the nine months ended September 30, 2012 compared to the corresponding periods of 2011. The decreases in AOI were primarily attributable to lower capacity and average realized energy prices, reduced generation and higher fuel prices, partially offset by lower planned maintenance costs and lower depreciation. Reduced generation primarily resulted from lower economic dispatch.

Included in fuel costs were unrealized gains (losses) of $2 million and $(4) million during the third quarters of 2012 and 2011, respectively, and $(2) million and $(6) million for the nine months ended September 30, 2012 and 2011, respectively, due to oil futures contracts that were accounted for as economic hedges. These contracts were entered into as economic hedges of the variable fuel price component of rail transportation costs.

Seasonality — Midwest Generation Coal Plants

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

Renewable Energy Projects

The following table presents additional data for EME's renewable energy projects:

Statistics
Generation (in GWh) ²	1,049			953			4,346			3,893

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


²	Includes renewable energy projects that are not consolidated by Edison International. Generation excluding unconsolidated projects was 902 GWh and 819 GWh in the third quarters of 2012 and 2011, respectively, and 3,761 GWh and 3,356 GWh in the nine months ended September 30, 2012 and 2011, respectively.

AOI from renewable energy projects decreased $7 million for both the three and nine months ended September 30, 2012 as compared to the corresponding periods of 2011. The decrease was primarily attributable to income allocated to third-party investors in Capistrano Wind Partners, partially offset by results of operations from projects that achieved commercial operations after the third quarter of 2011. For additional information, see "Edison International Notes to Consolidated Financial Statements—Note 3. Variable Interest Entities—Projects or Entities that are Consolidated—Capistrano Wind Equity Capital."

The following table reconciles AOI from EME's renewable energy projects to its operating income (loss) as included in EME's consolidated statements of operations:



	Three Months Ended September 30,						Nine Months Ended September 30,

Energy Trading

AOI from energy trading activities increased $10 million for the three months ended September 30, 2012 as compared to the corresponding period of 2011. The increase was mainly due to higher revenues from trading power and MISO congestion contracts.

Adjusted Operating Income from Other Projects

Doga. EME received a distribution from the Doga project of $11 million in the second quarter of 2012 compared to $26 million in the second quarter of 2011. Distributions in the second quarter of 2011 were higher due to release of funds from restricted cash once project debt obligations were repaid. AOI is recognized when cash is distributed as the Doga project is accounted for on the cost method.

Sunrise Project. AOI from the Sunrise project decreased $29 million and $19 million in the three and nine months ended September 30, 2012, respectively, compared to the corresponding periods of 2011. The decreases in AOI were due to the transition off of a long-term power purchase agreement to merchant operations. Sunrise will continue to operate as a merchant project unless a new power purchase agreement is executed. The profitability of Sunrise as a merchant generator is dependent on market prices for power and natural gas and future results may differ from historical earnings. For additional information, see "EMG: Market Risk Exposures—Commodity Price Risk."

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

Interest Income (Expense)



	Three months ended September 30,						Nine months ended September 30,
(in millions)	2012			2011			2012			2011
Interest income	$	1		$	—		$	2		$	2

	$	(83	)	$	(81	)	$	(253	)	$	(243	)

EMG's interest expense increased $2 million and $10 million for the three and nine months ended September 30, 2012, respectively, compared to the corresponding periods of 2011. The 2012 increase in interest expense was primarily due to higher debt balances from new project financings partially offset by higher capitalized interest. Capitalized interest was

$9 million and $4 million for the third quarter of 2012 and 2011, respectively, and $22 million and $20 million for the nine months ended September 30, 2012 and 2011, respectively. The 2012 increase in capitalized interest was due to the Walnut Creek project construction.

Income Taxes

The table below provides a reconciliation of income tax benefit computed at the federal statutory income tax rate:

*	Not meaningful

EMG's effective tax rates were impacted by production tax credits, estimated state income tax benefits allocated from Edison International, and taxes on income allocated to noncontrolling interests. Estimated state income tax benefits allocated from Edison International of $7 million and $5 million were recognized for the nine months ended September 30, 2012 and 2011, respectively. The benefit for state taxes was lower in 2012 due to an adjustment in state apportionment factors.

Results of Discontinued Operations

Income (loss) from discontinued operations, net of tax, was $(76) million and $15 million for the third quarters ended September 30, 2012 and 2011, respectively and $(129) million and $(3) million for the nine months ended September 30, 2012 and 2011, respectively. Discontinued operations primarily reflects the results of Homer City. The decreases in earnings reflect a pre-tax charge of $113 million ($68 million after tax) recorded in the third quarter of 2012 associated with the planned divestiture of Homer City. In addition, Homer City's earnings were impacted by lower average realized energy prices and higher coal and emission allowance costs, partially offset by lower plant maintenance costs, as compared to the corresponding periods of 2011. For additional information, see "Edison International Notes to Consolidated Financial Statements—Note 18. Discontinued Operations."

LIQUIDITY AND CAPITAL RESOURCES

Available Liquidity

The following table summarizes available liquidity at September 30, 2012



(in millions)	Cash and Cash Equivalents
EME as a holding company	$	325
EME subsidiaries without contractual dividend restrictions
Midwest Generation	142
Other EME subsidiaries	160
EME corporate and Midwest Generation cash and cash equivalents	627
EME subsidiaries with contractual dividend restrictions
Other EME subsidiaries	71
Other EMG subsidiaries	153
Total	$	851

See "Edison International Overview—Management Overview of EMG" for a discussion of EME's liquidity.

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

EME, as a holding company, does not directly operate any revenue-producing generation facilities. EME relies on cash distributions and tax payments from its projects and tax benefits received under a tax-allocation agreement with Edison International to meet its obligations, including debt service obligations on long-term debt. The timing and amount of distributions from EME's subsidiaries may be restricted. For further details, including the current restrictions on distributions from the Homer City facility, see "—Debt Covenants and Dividend Restrictions."

Capital Investment Plan

Forecasted capital expenditures through 2014 by EME's subsidiaries for existing projects and corporate activities are as follows:

¹	For additional information, see "Edison International Overview—Management Overview of EMG—Midwest Generation Environmental Compliance Plans and Costs."

Midwest Generation Capital Expenditures

Midwest Generation plants' forecasted environmental expenditures are based on retrofitting Powerton Units 5 and 6, Joliet Units 7 and 8 and Will County Units 3 and 4, using dry scrubbing with sodium-based sorbents and upgrading particulate removal systems to comply with CPS requirements for SO ₂ emissions and the US EPA's regulation on hazardous air pollutant emissions. Apart from the Fisk and Crawford Stations, which ceased operations in September 2012, decisions regarding

whether or not to proceed with retrofitting any particular remaining units to comply with CPS requirements for SO ₂ emissions, including those that have received permits, are subject to a number of factors, such as market conditions, regulatory and legislative developments, liquidity and forecasted commodity prices and capital and operating costs applicable at the time decisions are required or made. Final decisions on whether to install controls, to install particular kinds of controls, and to actually expend capital or continue with the expenditure of capital will be made as required, subject to the requirements of the CPS and other applicable regulations. Furthermore, the timing of commencing capital projects may vary from the amounts set forth in the above table. For additional discussion, see "Edison International Overview—Management Overview of EMG—Midwest Generation Environmental Compliance Plans and Costs."

Plant capital expenditures for Midwest Generation includes capital projects for boiler and turbine controls, major boiler components and electrical systems.

Net Cash Provided (Used) by Operating Activities

The decrease in cash provided by operating activities from continuing operations in 2012 as compared to 2011 was primarily attributable to decreased operating income due to declining energy prices, increased operating costs and higher interest payments due to new energy project financings. The decrease was also attributable to EME tax-allocation payments made, net of receipts, of $168 million in 2012 compared to tax-allocation payments received, net of payments made, of $182 million in 2011. Operating cash flow was also impacted by timing of cash receipts and disbursements related to working capital items.

Net Cash Provided by Financing Activities

The change in financing activities is primarily due to cash contributions from noncontrolling interests and the timing of financings and repayment of debt as summarized in the following table:

Credit Ratings

Credit ratings for EME and EMMT as of September 30, 2012 were as follows:



	Moody's Rating	S&P Rating	Fitch Rating
EME ¹	Ca	CCC	C
EMMT	Not Rated	CCC	Not Rated


¹	Senior unsecured rating.

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

EMG does not have any "rating triggers" contained in subsidiary financings that would result in a requirement to make equity contributions or provide additional financial support to its subsidiaries, including EMMT. However, coal contracts at Midwest Generation include provisions that provide the right to request additional collateral to support payment obligations for delivered coal and may vary based on Midwest Generation's credit ratings.

Margin, Collateral Deposits and Other Credit Support for Energy Contracts

Hedging Activities

To reduce its exposure to market risk, EME hedges a portion of its electricity price exposure through EMMT. In connection with entering into contracts, EMMT may be required to support its risk of nonperformance through parent guarantees, margining or other credit support. EME has entered into guarantees in support of EMMT's hedging and trading activities. However, EME has historically also provided collateral in the form of cash and letters of credit for the benefit of counterparties. For further details, see "Edison International Notes to Consolidated Financial Statements—Note 6. Derivative Instruments and Hedging Activities."

Future cash collateral requirements may be higher than the margin and collateral requirements at September 30, 2012 , if wholesale energy prices change or if EMMT enters into additional transactions. EME estimates that margin and collateral requirements for energy and congestion contracts outstanding as of September 30, 2012 could increase by approximately $26 million over the remaining life of the contracts using a 95% confidence level.

Intercompany Tax-Allocation Agreement

EMG and its subsidiaries, EME and Edison Capital, are included in the consolidated federal and combined state income tax returns of Edison International and are eligible to participate in tax-allocation payments with other subsidiaries of Edison International in circumstances where domestic tax losses are incurred. The right of EME and Edison Capital to receive and the amount of and timing of tax-allocation payments are dependent on the inclusion of EME and Edison Capital in the consolidated income tax returns of Edison International and its subsidiaries and other factors, including the consolidated taxable income of Edison International and its subsidiaries, the amount of net operating losses and other tax items of EMG's subsidiaries, and other subsidiaries of Edison International and specific procedures regarding allocation of state taxes. EMG receives tax-allocation payments for tax losses when and to the extent that the consolidated Edison International group generates sufficient taxable income in order to be able to utilize EMG's consolidated tax losses in the consolidated income tax returns for Edison International and its subsidiaries. Based on the application of the factors cited above, EMG is obligated during periods it generates taxable income to make payments under the tax-allocation agreements. Tax-allocation receipts and payments may also be affected by redetermination of utilization of net operating losses resulting from carryback of net operating losses on a consolidated basis or settlement of tax liabilities for prior periods. In September 2012, EME made a tax-allocation payment to Edison International of approximately $185 million related to the displacement, under the tax-allocation agreement, of tax benefits previously received for 2009 federal income taxes. Edison International expects to pay federal and state tax-allocation payments to EME during the next six months of approximately $160 million related to 2012 income taxes. The timing of the receipt of or payment of funds due under the tax-allocation agreement is dependent on future taxable income of Edison International. Estimates of future taxable income are uncertain and changes in estimates may have a material impact on the consolidated financial statements.

Debt Covenants and Dividend Restrictions

For a description of the covenants binding EME's principal subsidiaries that may restrict the ability of those entities to make distributions to EME directly or indirectly through the other holding companies owned by EME, refer to "Debt Covenants and Dividend Restrictions " in the year-ended 2011 MD&A. Upon the expiration of the Midwest Generation credit facility on June 29, 2012, the debt-to-capitalization ratio as discussed in the Form 10-K is no longer required and Midwest Generation is also no longer contractually restricted in its ability to make distributions to EME. For further information, see "—Available Liquidity." Homer City is restricted from making distributions.

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

EME is restricted under applicable agreements from selling or disposing of assets, which includes distributions, if the aggregate net book value of all such sales and dispositions during the most recent 12-month period would exceed 10% of consolidated net tangible assets as defined in such agreements computed as of the end of the most recent fiscal quarter preceding the sale or disposition in question. At September 30, 2012 , the maximum permissible sale or disposition of EME's assets was $727 million.

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

Derivative Instruments

Fair Value Disclosures

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

Commodity Price Risk

Ene rgy Price Risk

Energy and capacity from the coal plants 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. Energy from 428 MW of merchant renewable energy projects is sold in the energy markets, primarily at spot prices in PJM and ERCOT.

The following table depicts the average historical market prices for energy per megawatt-hour at the Northern Illinois Hub related to the Midwest Generation plants for the first nine months of 2012 and 2011:



	24-Hour Average Historical Market Prices ¹
	2012		2011
Northern Illinois Hub	$	28.56	$	35.30


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

The following table sets forth the forward market prices for energy per megawatt-hour as quoted for sales into the Northern Illinois Hub at September 30, 2012 :



	24-Hour Forward Energy Prices ¹
	Northern Illinois Hub
2012
October		$	27.35
November		27.17
December		30.22
2013 calendar "strip" ²		$	30.60
2014 calendar "strip" ²		$	31.31


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


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

Power prices remained low in the first nine months of 2012 due to an abundance of low-priced natural gas and the sales volume from the Midwest Generation plants has been correspondingly affected. Forward market prices at the Northern Illinois Hub fluctuate as a result of a number of factors, including natural gas prices, transmission congestion, changes in market rules, electricity demand (which in turn is affected by weather, economic growth, and other factors), plant outages in the region, and the amount of existing and planned power plant capacity. The actual spot prices for electricity delivered by the Midwest Generation plants into these markets may vary materially from the forward market prices set forth in the preceding table.

EMMT engages in hedging activities for the coal plants to hedge the risk of future change in the price of electricity. The following table summarizes the hedge positions at September 30, 2012 for electricity expected to be generated during the remainder of 2012 and in 2013:



	2012			2013
	MWh (in thousands)	Average price/ MWh ¹		MWh (in thousands)	Average price/ MWh ¹
Midwest Generation plants ²	2,028	$	37.53	3,615	$	36.55

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


²	Includes hedging transactions primarily at the Northern Illinois Hub and to a lesser extent the AEP/Dayton Hub, both in PJM, and the Indiana Hub in MISO.

Sunrise Project

Beginning July 1, 2012, EME's 50% owned Sunrise project, which EME accounts for on the equity method, will operate as a merchant generator and sell power at spot prices from its 572 MW facility into the California ISO market, unless a power purchase agreement is obtained. Spot prices are currently expected to be between the price for the NP15 and SP15 trading locations in that market. As a gas-fired merchant generator, Sunrise purchases natural gas based on spot prices and, accordingly, the plant is dispatched in periods when the power prices exceed the cost of fuel and other variable operations and maintenance costs. Historically, Sunrise has operated more during the summer months due to higher demand driven by warm weather.

Capacity Price Risk

Under the RPM, capacity commitments are made in advance to provide a long-term pricing signal for construction and maintenance of capacity resources. The following table summarizes the status of capacity sales for Midwest Generation at September 30, 2012:



	RPM Capacity Sold in Base Residual Auction			Other Capacity Purchases, Net of Sales ¹				Aggregate Average Price per MW-day
	MW	Price per MW-day		MW		Average Price per MW-day		Aggregate Average Price per MW-day
October 1, 2012 to May 31, 2013	4,704	$	16.46	(450	)	$	15.67	$	16.54
June 1, 2013 to May 31, 2014	4,650	27.73		(2,430	)	7.01		50.40
June 1, 2014 to May 31, 2015	4,625	125.99		(700	)	5.54		147.47
June 1, 2015 to May 31, 2016	3,620	136.00		—		—		136.00


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

The RPM auction capacity prices for the delivery period of October 1, 2012 to May 31, 2013 and June 1, 2013 to May 31, 2014 varied between different areas of PJM. In the western portion of PJM, affecting Midwest Generation, the prices of $16.46 per MW-day and $27.73 per MW-day were substantially lower than capacity prices in other areas.

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

Basis Risk

During the nine months ended September 30, 2012, day-ahead prices at the individual busbars of the Midwest Generation plants compared to the AEP/Dayton Hub, Indiana Hub (Cinergy Hub) and Northern Illinois Hub were on average lower by 6%, lower by 1% and higher by 1%, respectively. During the nine months ended September 30, 2011, day-ahead prices at the individual busbars of the Midwest Generation plants were lower compared to the AEP/Dayton Hub and Indiana Hub (Cinergy Hub) by an average of 12% and 2%, respectively. Differences in day-ahead pricing between the individual busbars of the Midwest Generation plants generally arise due to transmission congestion.

Coal Price Risk

The Midwest Generation plants purchase coal primarily from the Southern PRB of Wyoming. Coal purchases are made under a variety of supply agreements. The following table summarizes the amount of coal under contract at September 30, 2012 , for the remainder of 2012 and the following two years:



	October through December 2012		2013	2014
Amount of Coal Under Contract in Millions of Equivalent Tons ¹		4.9	11.1	9.8


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

Midwest Generation is subject to price risk for purchases of coal that are not under contract. Market prices of PRB coal based on 8,800 Btu per pound heat content and 0.8 pounds of SO ₂ per MMBtu sulfur content decreased to a price of $9.20 per ton at September 28, 2012, compared to a price of $12.75 per ton at December 30, 2011, as reported by the EIA.

Credit Risk

The credit risk exposure from counterparties of merchant energy hedging and trading activities is measured as the sum of net receivables (accounts receivable less accounts payable) and the current fair value of net derivative assets. EME's subsidiaries enter into master agreements and other arrangements in conducting such activities which typically provide for a right of setoff in the event of bankruptcy or default by the counterparty. At September 30, 2012, the balance sheet exposure as described above, by the credit ratings of EME's counterparties, was as follows:



	September 30, 2012
(in millions)	Exposure ²		Collateral			Net Exposure
Credit Rating ¹
A or higher	$	91	$	—		$	91
A-	8		(8		)	—
BBB+	4		—			4
BBB	—		—			—
BBB-	—		—			—
Below investment grade	29		(29		)	—
Total	$	132	$	(37	)	$	95


¹	EME 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 sheet, except for any related accounts receivable.

The credit risk exposure set forth in the above table is composed of $64 million of net accounts receivable and payables and $68 million representing the fair value of derivative contracts. The exposure is based on master netting agreements with the related counterparties. Credit ratings may not be reflective of the actual related credit risks. In addition to the amounts set forth in the above table, EME's subsidiaries have posted a $79 million cash margin in the aggregate with PJM, NYISO,

MISO, clearing brokers and other counterparties to support hedging and trading activities. The margin posted to support these activities also exposes EME to credit risk of the related entities.

The Midwest Generation coal plants sell electric power generally into the PJM market by participating in PJM's capacity and energy markets or transacting in capacity and energy on a bilateral basis. Sales into PJM accounted for approximately 73% of EME's consolidated operating revenues for the nine months ended September 30, 2012. At September 30, 2012, EME's account receivable due from PJM was $53 million.

EME's turbine supply agreements contain significant suppliers' obligations related to the manufacturing and delivery of turbines, and payments, for delays in delivery and for failure to meet performance obligations and warranty agreements. EME's reliance on these contractual provisions is subject to credit risks. Generally, these are unsecured obligations of the turbine manufacturer. A material adverse development with respect to EME's turbine suppliers may have a material impact on EME's projects and development efforts. Two of EME's wind turbine suppliers, Suzlon and Clipper, are currently experiencing significant adverse credit and liquidity issues. As a result, EME's ability to enforce performance and warranty guarantees is subject to the credit risk of these counterparties.

Interest Rate Risk

Interest rate changes can affect earnings and the cost of capital for capital improvements or new investments in power projects. EME mitigates the risk of interest rate fluctuations 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 further details, see "Edison International Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements" and "—Note 6. Derivative Instruments and Hedging Activities."

EDISON INTERNATIONAL PARENT AND OTHER

RESULTS OF OPERATIONS

Results of operations for Edison International Parent and Other includes amounts from other Edison International subsidiaries that are not significant as a reportable segment, as well as intercompany eliminations.

Edison International Parent and Other loss from continuing operations was $36 million and $13 million for the three- and nine-month periods ended September 30, 2012, respectively, compared to $48 million and $19 million for the same periods in 2011. In the third quarter of 2012, Edison International and EME recorded income tax charges of $13 million and $16 million, respectively, related to changes in California apportionment rates used in prior periods. The charges related to an update of Edison International's assessment of uncertain tax positions following a recent court case. In addition, Edison International updated its estimated long-term California apportionment rate applicable to consolidated deferred income taxes as a result of reductions in EME's projected sales resulting in income charges during the third quarter of $16 million.

LIQUIDITY AND CAPITAL RESOURCES

Edison International Parent liquidity and its ability to pay operating expenses and dividends to common shareholders is dependent on dividends from SCE, tax-allocation payments under its tax-allocation agreements with its subsidiaries, and access to bank and capital markets.

During the second quarter of 2012, Edison International Parent replaced its credit facilities with a new $1.25 billion five-year revolving credit facility that matures May 2017. The following table summarizes the status of the Edison International Parent credit facility at September 30, 2012:



(in millions)	Edison International (parent)
Commitment	$	1,250
Outstanding borrowings	(28		)
Amount available	$	1,222

Edison International has a debt covenant in its credit facility that requires a consolidated debt to total capitalization ratio of less than or equal to 0.65 to 1. The ratio of debt to total capitalization is defined in the credit agreement and generally excludes the consolidated debt and total capital of EME. At September 30, 2012, Edison International's consolidated debt to total capitalization ratio was 0.48 to 1.

Historical Segment Cash Flows

The table below sets forth condensed historical cash flow information for Edison International Parent and Other.



	Nine months ended September 30,
(in millions)	2012		2011
Net cash provided (used) by operating activities	$	51	$	(13	)
Net cash provided by financing activities	36		21
Net cash provided by investing activities	—		1
Net increase in cash and cash equivalents	$	87	$	9

Net Cash Used by Operating Activities

Net cash provided by operating activities primarily relate to interest, operating costs and income taxes of Edison International Parent. In addition to these factors, Edison International Parent funded a portion of the 2011 tax-allocation payments due by Edison Capital in consideration of an intercompany note receivable.

Net Cash Provided by Financing Activities

Financing activities for the first nine months of 2012 were as follows:


•	Paid $318 million of dividends to Edison International common shareholders.


•	Received $349 million of dividend payments from SCE.

Financing activities for the first nine months of 2011 were as follows:


•	Paid $313 million of dividends to Edison International common shareholders.


•	Received $345 million of dividend payments from SCE.


•	Repaid $9 million under Edison International's line of credit.
