Edison International's thirdfirst quarter 20172023 earnings increased $49$226 million from the thirdfirst quarter of 2016, comprised of2022, resulting from an increase in SCE's earnings of $30$223 million and a decrease in Edison International Parent and Other's losses of $19$3 million. SCE's higher net earnings consisted of $199 million of lower non-core losses and $24 million of higher core earnings. Edison

International Parent and Other's lower losses consisted of $18 million of higher non-core earnings and $15 million of higher core losses.

The increase in SCE's core earnings at SCEfor the three months ended March 31, 2023 from the same period in 2022 was primarily due to the escalation mechanism set forth in the 2015 GRC decision.

Edison International's earnings for the nine months ended September 30, 2017 increased $128 million from the nine months ended September 30, 2016, comprised of an increase in SCE's earnings of $73 million, a decrease in Edison International Parent and Other's losses of $54 million, and a decrease in losses from discontinued operations of $1 million. The increase in earnings at SCE was primarily related to an increase in revenue from the escalation mechanism set forth in the 20152021 GRC final decision, and lower operation and maintenance expenses, partially offset by a reduction in CPUC revenue related to prior overcollections and higher net financing costs.
interest expense.

The increase in Edison International Parent and Other's decrease incore losses for the three and nine months ended September 30, 2017March 31, 2023 was due to lower core losses of $19 million and $58 million, respectively, and lower non-core earnings of $4 million for the nine months ended September 30, 2017. The decrease in core losses for the quarter wasprimarily due to higher income tax benefits resulting from net operating loss carrybacks frominterest expense.

Consolidated non-core items for the filingthree months ended March 31, 2023 and 2022 primarily included:

Charges of $52 million ($38 million after-tax) recorded in 2023 and $53 million ($38 million after-tax) recorded in 2022 from the amortization of SCE's contribution to the Wildfire Insurance Fund. See "Notes to Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies" in the 2022 Form 10-K for further information.
Charges of $90 million ($65 million after-tax) recorded in 2023 and $396 million ($285 million after-tax) recorded in 2022 for 2017/2018 Wildfire/Mudslide Events claims and expenses, net of recoveries. See "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies" for further information.
A charge of $30 million ($21 million after-tax) recorded in 2023 for estimated losses related to the reasonableness review of recorded San Onofre Units 2 and 3 decommissioning costs in the 2021 NDCTP. See "Liquidity and Capital Resources—SCE—Decommissioning of San Onofre" for more information.
Customer revenues of $22 million ($18 million after-tax) recorded in 2023 related to an EIS insurance contract. See "Notes to Consolidated Financial Statements—Note 17. Related-Party Transactions" for further information.

See "Results of Operations" for discussion of SCE's and Edison International Parent and Other's results of operations.

Customer-funded Self-Insurance

In April 2023, the CPUC issued a proposed decision which, if adopted, would approve a joint petition for modification of the 2016 tax returns in 2017.2021 GRC decision filed by SCE, The year-to-date decrease also reflects higher income tax benefits related to stock option exercisesUtility Reform Network and the 2017 settlement of federal income tax audits for 2007 – 2012.

Capital Program
SCE's capital expenditures forecast for the 2017 – 2020 period has been revised since the filing of the 2016 Form 10-K, as indicated in the table below. The update also reflects SCE's revised requested capital expenditures for 2018 – 2020 resulting from SCE's 2018 GRC rebuttal testimony, filed in June 2017.
The 2017 capital program had originally included expenditures of $182 million for grid modernization capital spending. SCE has requested CPUC approval of a memorandum account to facilitate recovery in rates of such expenditures. The memorandum account has not yet beenPublic Advocates Office. If approved by the CPUC, the petition would allow SCE to expand its use of self-insurance. The self-insurance program would be funded through CPUC-jurisdictional rates with $150 million collected for the second half of 2023 and, may not be approved. Certainin the absence of wildfire-related claims, $300 million collected for 2024. These modifications would result in a reduction to current revenue requirements of $80 million in 2023 and, subject to adjustment, $160 million in 2024. If losses are accrued for wildfire-related claims, the petition for modification contains an adjustment mechanism which would increase rates in subsequent years to allow for recovery of the grid modernizationamounts accrued, subject to a shareholder contribution of 2.5% of any self-insurance costs ultimately paid exceeding $500 million in any year, up to a maximum annual contribution of $12.5 million.

Capital Program

Total capital expenditures promote safety(including accruals) were $1.3 billion for both the first three months ended March 31, 2023 and reliability as well as facilitate integration of distributed energy resources and are2022. SCE expects to file its 2025 GRC application with the focus of SCE's reduced grid modernizationCPUC in May 2023 including its capital expenditures in 2017. These expenditures are included in traditional distribution capital expendituresexpenditure requests for 2017 in the table below.

Traditional capital expenditures for 2017 reflect SCE's forecast capital expenditures for CPUC and FERC capital projects. Traditional capital expenditures for 2018 – 2020 reflect the amounts requested in the 2018 GRC filing and subsequently updated in SCE's rebuttal testimony as well as the expected spending for FERC capital projects. Recovery for 2017 – 2020 planned expenditures for traditional capital projects under FERC jurisdiction will be pursued through FERC-authorized mechanisms. The CPUC has approved 81%, 89%, and 92% of the traditional capital expenditures requested in the 2009, 2012, and 2015 GRC decisions, respectively. While SCE cannot predict the level of traditional capital spending that will be approved in the 2018 GRC decision, management is not aware of factors that would cause the percentage of SCE's request that is ultimately approvedyears 2025 to be materially different from what has been approved in recent GRC decisions. SCE does not have prior approval experience with grid modernization capital expenditures and, therefore, is unable to predict an expected outcome. Forecasted expenditures for FERC capital projects are subject to change due to timeliness of permitting, licensing and regulatory approvals.2028. For further information regarding updates for large transmission and substation projects,the capital program, see "Liquidity and Capital Resources—SCE—Capital Investment Plan."
It is unlikely that SCE will receive a 2018 GRC decision in 2017. It is also uncertain whether SCE will receive firm guidance on grid modernization spending as part of the DRP proceeding during 2017. SCE is currently developing an approach for 2018 capital spending, based on these contingencies, which will allow SCE to ramp up its capital spending program to meet the rate base ultimately authorizedPlan" and "Management Overview—Capital Program" in the 2018 GRC decision while minimizing the associated risk2022 MD&A.

2017/2018 General Rate Case

In September 2016, SCE filed its 2018 GRC application for the three-year period 2018 – 2020, which requested a 2018 revenue requirement of $5.885 billion, an increase of $222 million over the projected 2017 GRC authorized revenue requirement. In June 2017 in its rebuttal testimony, SCE revised its requested 2018 revenue requirement to $5.859 billion, which would be a $196 million increase. The rebuttal testimony also proposed post-test year increases in 2019 and 2020 of $480 million and $556 million, respectively.
In April 2017, the ORA recommended that SCE's original requested 2018 base revenue requirement be decreased by approximately $208 million, comprised of approximately $164 million in operations and maintenance expense reductions and approximately $44 million in capital-related revenue requirement reductions largely related to the proposed reduction of 100% of grid modernization capital spending. To the extent any spending is authorized, the ORA proposed capturing grid modernization spending in a memorandum account for review in the 2021 GRC. TURN recommended reductions of 78% of grid modernization capital expenditures in 2018 and initially recommended adjustments to rate base for historical capital expenditures, including a reduction of $700 million, primarily related to certain distribution infrastructure replacement programs. In a September 2017 filing, TURN reduced their recommended rate base adjustment to approximately $550 million. The impact of TURN's updated recommendations would decrease SCE's original requested 2018 base revenue requirement by approximately $114 million.
Public participation hearings are scheduled in mid-November and update filings are due in early December. While SCE requested that the CPUC issue a final decision by the end of 2017, it is unlikely that such timing will be achieved. If the schedule for a final decision is delayed, SCE will request the CPUC to issue an order directing that the authorized revenue requirement changes be effective January 1, 2018. SCE cannot predict the revenue requirement the CPUC will ultimately authorize for 2018 through 2020 or forecast the timing of a final decision.


Permanent Retirement of San Onofre
Replacement steam generators were installed at San Onofre in 2010 and 2011. On January 31, 2012, a leak suddenly occurred in one of the heat transfer tubes in San Onofre's Unit 3 steam generators. The Unit was safely taken off-line and subsequent inspections revealed excessive tube wear. Unit 2 was off-line for a planned outage when areas of unexpected tube wear were also discovered. On June 6, 2013, SCE decided to permanently retire Units 2 and 3.
San Onofre CPUC Proceedings
Wildfire/Mudslide Events

As discussed in the year-ended 2016 MD&A, in a December 2016 joint ruling,2022 Form 10-K, multiple lawsuits and investigations related to the Assigned Commissioner2017/2018 Wildfire/Mudslide Events have been initiated against SCE and Edison International. SCE has previously settled claims under the Local Public Entity Settlement, the TKM Subrogation Settlement, the Woolsey Subrogation Settlement and the Assigned ALJ expressed concerns about the extent to which the failure to timely report ex parte communications had impacted the settlement negotiations and directedSED Agreement. In addition, SCE and SDG&E to meet and conferhas also entered into settlements with the other partiesapproximately 10,000 individual plaintiffs in the San Onofre OII to consider changing the terms2017/2018 Wildfire/Mudslide Events litigation as of the San Onofre OII Settlement Agreement. In March 2017, SCE31, 2023.

Each reporting period, management reviews its loss estimates for remaining alleged and the parties participating in the meet-and-confer process initiated a mediation of the issues identified in the December 2016 joint ruling. On August 15, 2017, SCE notified the CPUC that the parties in the San Onofre OII Settlement Agreement were unable to reach agreement on possible changespotential claims related to the settlement unanimously approved by2017/2018 Wildfire/Mudslide Events. As a result of management's first quarter 2023 review, a $90 million increase in estimated losses for the CPUC in 2014. In connection with2017/2018 Wildfire/Mudslide Events as of March 31, 2023 was recorded. As a result, SCE recorded expected recoveries through FERC electric rates of $6 million against the termination ofcharge. The resulting net charge to earnings was $84 million ($61 million after-tax).

Estimated losses for the meet-and-confer process, SCE asked the CPUC to affirm that the San Onofre OII Settlement Agreement is fair, reasonable and in the public interest. Other parties to the meet-and-confer process petitioned the CPUC2017/2018 Wildfire/Mudslide Events litigation are based on a broad rangenumber of litigation positions, certain of which included substantial additional disallowances.

On October 10, 2017, the Assigned Commissioner and ALJ issued a Ruling ordering additional process to resolve the San Onofre OII. The Ruling did not set aside nor confirm the San Onofre OII Settlement Agreement but stated that the CPUC required an additional record to address the appropriate cost allocation for the premature shutdown of San Onofre Units 2 and 3, in the event the CPUC decides that the settlement does not meet the CPUC's standards for approval of settlements. The Ruling sets an expedited schedule with a status conference on November 7, 2017 and hearings tentatively scheduled to end in March 2018. The CPUC has not announced the expected timing for a decision.
SCE has recorded a regulatory asset of $730 million at September 30, 2017 to reflect the expected recoveries under the San Onofre OII Settlement Agreement. SCE assessed the San Onofre regulatory asset at September 30, 2017 and continues to conclude that the asset is probable, though not certain, of recovery based on SCE's knowledge of facts and judgment in applying the relevant regulatory principles to the issue. Such judgment is subject to uncertainty, and regulatory principles and precedents are not necessarily bindingassumptions and are subject to interpretation.
MHI Claims
In March 2017,change as additional information becomes available. Actual losses incurred may be higher or lower than estimated based on several factors, including the uncertainty in estimating damages that have been or may be alleged. For instance, SCE received a decision fromwill receive additional information with respect to damages claimed as the International Chamberclaims mediation processes progress. Other factors that can cause actual losses incurred to be higher or lower than estimated include the ability to reach settlements and the outcomes of Commerce International Courtsettlements reached through the ongoing claims mediation processes, uncertainties related to the sufficiency of Arbitration oninsurance held by plaintiffs, uncertainties related to the litigation processes, including whether plaintiffs will ultimately pursue claims, against MHI regarding failureuncertainty as to the legal and factual determinations to be made during litigation, including uncertainty as to the contributing causes of the replacement steam generators2017/2018 Wildfire/Mudslide Events, the complexities associated with fires that MHI supplied for San Onofre. The net recovery awardedmerge and whether inverse condemnation will be held applicable to SCE was initially determinedwith respect to damages caused by the Montecito Mudslides, and the uncertainty as to how these factors impact future settlements.

Through March 31, 2023, SCE has accrued estimated losses of $8.8 billion, expected recoveries from insurance of $2.0 billion and expected recoveries through FERC electric rates of $382 million related to the 2017/2018 Wildfire/Mudslide Events. The after-tax net charges to earnings recorded through March 31, 2023 have been $4.7 billion.

As of March 31, 2023, SCE had paid $7.8 billion under executed settlements and had $135 million to be $52 million. An adjustmentpaid under executed settlements, including $120 million to be paid under the SED Agreement, related to the interest awarded2017/2018 Wildfire/Mudslide Events. As of the same date, SCE had recovered $2.0 billion through insurance and approximately $319 million through FERC-jurisdictional electric rates.

After giving effect to SCE subsequently reducedall payment obligations under settlements entered into through March 31, 2023, including under the net recoverySED Agreement, Edison International's and SCE's best estimate of expected losses for remaining alleged and potential claims related to $47the 2017/2018 Wildfire/Mudslide Events was $988 million. As of the same date, SCE had assets for expected recoveries through FERC electric rates of $63 million on its consolidated balance sheets and had exhausted expected insurance recoveries related to the 2017/2018 Wildfire/Mudslide Events. Edison International and SCE may incur a resultmaterial loss in excess of uncertainty associatedamounts accrued in connection with the allocationremaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events.

SCE will seek CPUC-jurisdictional rate recovery of prudently-incurred losses and related costs realized in connection with the 2017/2018 Wildfire/Mudslide Events in excess of available insurance and FERC-jurisdictional recoveries, other than for any obligations under the SED Agreement. Based on Edison International's and SCE's current best estimate of expected losses for the 2017/2018 Wildfire/Mudslide Events, SCE currently expects to seek CPUC-jurisdictional rate recovery of approximately $6 billion by filing several future applications with the CPUC. SCE targets the third quarter of 2023 for the first of such cost recovery applications, and expects to request recovery of approximately $2 billion in that filing

related to TKM. SCE's plans with respect to these filings may be delayed or modified. For example, the filings may be delayed if proceedings related to the 2017/2018 Wildfire/Mudslide Events do not progress as anticipated. SCE believes that, in light of the award underCPUC's decision in a cost recovery proceeding involving SDG&E arising from several 2007 wildfires in SDG&E's service area, there is substantial uncertainty regarding how the San Onofre OII Settlement Agreement,CPUC will interpret and apply its prudency standard to an investor-owned utility in wildfire cost-recovery proceedings for fires ignited prior to the adoption of AB 1054 on July 12, 2019. Accordingly, while the CPUC has not made a determination regarding SCE's prudency relative to any of the 2017/2018 Wildfire/Mudslide Events, SCE recorded a regulatory liability foris unable to conclude, at this time, that uninsured CPUC-jurisdictional wildfire-related costs related to the net recovery.

2017/2018 Wildfire/Mudslide Events are probable of recovery through electric rates.

Cost of Capital
In July 2017, the CPUC issued a final decision that adopted the petition previously filed by SCE, Pacific Gas & Electric Company, SDG&E,Southern California Wildfires and SoCalGas (collectively, the "Investor-Owned Utilities"), ORA, and TURN to modify the prior CPUC decisions addressing the Investor-Owned Utilities' costs of capital. The decision extended the deadline for the next Investor-Owned Utilities cost of capital application to April 2019, reset SCE's authorized cost of long-term debt and preferred stock, and established SCE's authorized ROE at 10.30%, both beginning January 1, 2018. In October 2017, the CPUC approved SCE's updated debt and preferred rates that SCE filedMudslides" in September 2017. For more information on the terms of the settling parties' petition, see "Management Overview—Regulatory Proceedings—Cost of Capital" in the year-ended 2016 MD&A.


FERC Formula Rates
In October 2017, SCE filed its 2018 annual update with the FERC with rates effective January 1, 2018. The update reflected a decrease in SCE's transmission revenue requirement of $13 million or 1.1% lower than amounts currently authorized in rates due to lower undercollections in previous periods. In addition, SCE filed its new formula rate with the FERC in October 2017 resulting in an additional decrease to the 2018 annual update of $6 million or 0.5%. Once the new formula rate is accepted by the FERC, it will supersede the existing formula rate, including the 2018 annual update, and could become effective as early as January 1, 2018. FERC has the authority and may suspend new rates for up to five months. If the new formula rate is suspended by the FERC, the 2018 transmission revenue requirement rate established in the 2018 annual update will be effective from January 1, 2018 until the end of the suspension of the new formula rate. The new formula rate will be subject to refund from the end of the suspension until it is ultimately approved by the FERC.
Power Charge Indifference Adjustment Rulemaking
In September 2017, the CPUC issued a Scoping Memo for its rulemaking to review, revise, and consider alternatives to the Power Charge Indifference Adjustment ("PCIA"), which is a charge that is applied to departing load customers and is intended to maintain bundled service customer indifference to departing load (including Community Choice Aggregator or CCA formation). The Scoping Memo adopts an overall goal of implementing the existing California statutory requirements regarding customer indifference for the proceeding. The CPUC has adopted a schedule with an expected resolution by the third quarter of 2018.

RESULTS OF OPERATIONS

Southern California Edison Company

SCE

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

Earning activities – representing revenue authorized by the CPUC and the FERC, which is intended to provide SCE with 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 earnings activities are revenue or penalties related to incentive mechanisms, other operating revenue, and regulatory charges or disallowances.
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, as well as non-bypassable rates collected for SCE Recovery Funding LLC. Cost-recovery activities include rates which provide recovery, subject to reasonableness review of, among other things, fuel costs, purchased power costs, public purpose related-program costs (including energy efficiency and demand-side management programs), certain operation and maintenance expenses (including vegetation management and wildfire insurance), and repayment of bonds and financing costs of SCE Recovery Funding LLC. SCE earns no return on these activities.

Earning Activities

Earning activities were primarily affected by the following:

Lower operating revenue of $34 million primarily due to the following:
A decrease of CPUC-related revenue of $183 million due to lower wildfire-related expenses that had been authorized for recovery during 2022 through tracks 2 and 3 of the 2021 GRC.
An increase of CPUC-related revenue of $102 million due to the escalation mechanism set forth in the 2021 GRC decision.
An increase of $63 million of revenue related to CSRP revenue requirements approved in 2022 and 2023. See "Liquidity and Capital Resources—SCE—Regulatory Proceedings" for more information.
A decrease of FERC-related revenue of $20 million due to lower wildfire-related claims and expenses to be recovered in FERC revenues.
An increase of FERC-related revenue of $6 million due to rate base growth.
Lower operation and maintenance expenses of $120 million.
In 2022, SCE recognized $241 million of previously deferred wildfire-related expenses upon approval of the 2021 GRC track 2, compared to $84 million previously deferred expenses recognized in 2023, primarily related to the 2021 GRC track 3 and CSRP approvals. The wildfire and CSRP-related expenses were offset in revenue above.
In 2023, SCE accrued $30 million in estimated losses relating to the 2021 NDCTP. See "Liquidity and Capital Resources—SCE— Decommissioning of San Onofre" for more information.
Lower operating revenue

8

A decrease in revenue of $227 million related to incremental tax benefits refunded to customers (offset in taxes below). The decrease in revenue resulted from $109 million of higher incremental tax repair benefits and $118 million of benefits recognized for tax accounting method changes.
An increase in CPUC revenue of approximately $63 million primarily due to the escalation mechanism as set forth in the 2015 GRC decision and $10 million of higher operating costs subject to balancing account treatment (primarily offset in depreciation expense below). These increases were partially offset by $9 million of lower revenue related to the extension of bonus depreciation.
Higher operation and maintenance costs of $8 million primarily due to transmission and distribution costs for line clearing and maintenance and higher information technology costs partially offset by the impact of SCE's operational and service excellence initiatives.
Higher property and other taxes of $7 million primarily due to a higher property assessed value in 2017.
Higher other operating income of $8 million due to the sale of utility property.
Higher interest expense of $12 million primarily due to increased borrowings.
Higher other income and expense of $10 million primarily due to higher AFUDC equity income.




Lower income taxes of $176 million primarily due to the following:
Higher income tax benefits in 2017 of $134 million related to flow through of incremental tax repair benefits and for tax accounting method changes (offset in revenue above).
Lower net income tax benefits in 2017 of $18 million for other property-related items, including cost of removal and depreciation deductions.
Lower pre-tax income for the third quarter of 2017, as discussed above.
Wildfire-related claims were impacted by charges of $90 million and $416 million recorded in 2023 and 2022, respectively, related to the 2017/2018 Wildfire/Mudslide Events. Also included in the charges are $6 million and
$9 million recorded in 2023 and 2022, respectively, for self-insured retention expenses related to the Post-2018 wildfires. See "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides."
Higher depreciation and amortization expense of $70 million primarily due to recognition of previously deferred CSRP-related expenses (offset in revenue above) and increased plant balances in 2023.
Higher property and other taxes of $21 million primarily due to higher property assessed value in 2023.
Higher interest expense of $85 million primarily due to increased long-term borrowing, higher interest rates on long-term debt, short-term debt and balancing account overcollections.
Higher other income of $57 million primarily due to a higher interest rate applied to balancing account undercollections.
See "Income Taxes" below for the explanation of the $69 million increase in income tax expenses.

Cost-Recovery Activities

Cost-recovery

Operating revenue and the corresponding operating expenses in cost-recovery activities were primarily affected by the following:

Higher purchased power and fuel costs of $64 million primarily driven by higher power and gas prices experienced in 2017 relative to 2016, partially offset by lower capacity costs.
Lower operation and maintenance expense of $29 million primarily driven by lower employee benefit and other labor costs and lower spending on various public purpose programs.

Higher purchased power and fuel costs of $281 million, primarily due to higher power and gas prices, partially offset by hedging gains.
Lower operation and maintenance costs of $265 million. In 2022, SCE recognized $160 million of wildfire-related expenses previously deferred upon obtaining approval of the 2021 GRC track 2 and $109 million of previously deferred uncollectible costs through a balancing account.

Earning Activities
Earning activities were primarily affected by the following:
Lower operating revenue of $29 million primarily due to the following:
An increase in CPUC revenue of approximately $181 million primarily due to the escalation mechanism as set forth in the 2015 GRC decision and $28 million of higher operating costs subject to balancing account treatment (primarily offset in depreciation expense below). These increases were partially offset by $24 million of lower revenue related to the extension of bonus depreciation and a $17 million revenue reduction for the expected refund to customers of prior overcollections identified in the second quarter of 2017.
A decrease in revenue of $185 million related to tax benefits refunded to customers (offset in income taxes below). The decrease in revenue resulted from $135 million of higher year-over-year incremental tax repair benefits recognized, $118 million of benefits recognized for tax accounting method changes, and a $65 million revenue reduction related to the tax abandonment of San Onofre. These decreases were partially offset by a 2016 revenue refund to customers of $133 million related to 2012 2014 incremental income tax deductions.
A decrease in FERC-related revenue of $31 million primarily related to higher operating costs in 2016 including amortization of the regulatory asset associated with the Coolwater-Lugo transmission project (offset in depreciation below) and a $7 million reduction to FERC revenue due to a change in estimate under the FERC formula rate mechanism.
Lower operation and maintenance costs of $43 million primarily due to the impact of SCE's operational and service excellence initiatives, lower storm-related activities and lower legal costs partially offset by higher transmission and distribution costs for line clearing and maintenance and information technology costs.
Higher depreciation and amortization expense of $31 million primarily related to depreciation on transmission and distribution investments partially offset by amortization of the regulatory asset related to Coolwater-Lugo plant recorded in 2016.
Higher property and other taxes of $11 million primarily due to a higher property assessed value in 2017.
Higher other operating income of $8 million due to the sale of utility property.
Higher interest expense of $34 million primarily due to increased borrowings and higher interest on balancing account overcollections in 2017.
Higher other income and expenses of $12 million primarily due to higher insurance benefits and higher AFUDC equity income.
Lower income taxes of $117 million primarily due to the following:
Higher income tax benefits of $109 million due to $149 million related to flow through of incremental tax repair benefits and for tax accounting method changes (offset in revenue above) and $39 million related to a tax deduction for the abandonment of San Onofre, partially offset by $79 million flow-through of 2012 – 2014 incremental income tax benefits in 2016.
Lower net income tax benefits in 2017 for other property-related items, including cost of removal and depreciation deductions.
Lower pre-tax income for the nine months ended September 30, 2017, as discussed above.
Cost-Recovery Activities
Cost-recovery activities were primarily affected by the following:
Higher purchased power and fuel costs of $166 million primarily driven by higher power and gas prices experienced in 2017 relative to 2016, partially offset by lower realized losses on hedging activities ($8 million in 2017 compared to $53 million in 2016) and lower capacity costs.
Lower operation and maintenance expense of $32 million primarily driven by lower employee benefit and other labor costs and lower spending on various public purpose programs.


Supplemental Operating Revenue Information

SCE's retail billed and unbilled revenue (excluding wholesale sales and balancing account overcollections/undercollections) was $4.0 billion and $9.0 billion for the three and nine months ended September 30, 2017, respectively, compared to $3.7 billion and $8.6 billion for the respective periods in 2016.
Retail billed and unbilled revenue for the three months ended September 30, 2017 was higher compared to the same period in 2016 due to a rate increase of $225 million and a sales volume increase of $85 million. The rate increase was due to implementation of the 2017 ERRA rate increase. The sales volume increase was primarily due to warmer weather experienced in the third quarter of 2017 compared to the same period in 2016. Retail billed and unbilled revenue for the nine months ended September 30, 2017 was higher compared to the same period in 2016 primarily due to the implementation of the 2017 ERRA rate increase.

As a result of the CPUC-authorized decoupling mechanism, SCE earningsrevenues are not affected by changes in retail electricity sales (see "Business—SCE—Overview of Ratemaking Process" in the 2016 Form 10-K).

Income Taxes

SCE's

The increase in income tax expense decreased by $176 million and $117of $69 million for the three and nine months ended September 30, 2017March 31, 2023 compared to the same periodsperiod in 2016.

2022 was primarily driven by the increase in pre-tax income. The effective tax rates were (7.6)%6.8% and 23.2%(30.1)% for the three months ended September 30, 2017March 31, 2023 and 2016,2022, respectively. The effective tax rates were 2.7% and 11.7% for the nine months ended September 30, 2017 and 2016, respectively. SCE'sSCE’s effective tax rate is lower thanbelow the federal statutory rate of 21% for 2023 and 2022 primarily due to CPUC'sthe CPUC’s 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. The effective tax rate decrease for the three and nine months ended September 30, 2017 was primarily due to higher incremental repair tax benefits and benefits recognized for tax accounting method changes, all of which will be refunded to customers. The change in the effective tax rate for the nine months ended September 30, 2017 also included higher tax benefits related to the ratemaking treatment on the San Onofre tax abandonment recorded in 2017 and lower tax benefits for the $133 million revenue refund to customers that was recorded in 2016.

See "Notes to Consolidated Financial Statements—Note 7.8. Income Taxes" for a reconciliation of the federal statutory rate of 35% to the effective income tax rates.

Strategic Review of Edison Energy Group Competitive Businesses
During the third quarter of 2017, Edison International completed a strategic review of Edison Energy Group's competitive businesses. The competitive businesses are undertaken through Edison Energy Group and include energy services provided by Edison Energy and distributed solar solutions provided by SoCore Energy. Edison International has concluded that it will evaluate strategic options, including potential sale opportunities for SoCore Energy and consolidate management across Edison Energy Group. Edison Energy will continue to pursue a proof of concept of its existing energy services and managed portfolio solutions practice for large energy users in the United States. Under the proof of concept, Edison Energy will seek to achieve a breakeven earnings run rate and 5% target customer penetration by the end of 2019.
In connection with the strategic review, Edison International evaluated the recoverability of goodwill and recorded an impairment of SoCore Energy's goodwill totaling $16.5 million ($10 million after-tax) in the second quarter of 2017. In light of the decision to evaluate sale opportunities for SoCore Energy, Edison International considered the application of held for sale accounting treatment under the applicable accounting guidance. However, Edison International concluded that, as of September 30, 2017, it was not probable that the investment in SoCore Energy would be sold within one year, therefore the long-lived assets of SoCore Energy were not subject to held for sale accounting treatment. Under held for sale accounting treatment, the net assets of SoCore Energy ($228 million at September 30, 2017) would be recorded at the lower of book value or as net realizable value, including transaction costs.

LIQUIDITY AND CAPITAL RESOURCES

Southern California Edison Company

SCE

SCE's ability to operate its business, fund capital expenditures, and implement its business strategy is dependent upon its cash flowflows and access to the bank and 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 obligations, and dividend payments to and equity contributions from Edison International, obligations to preference shareholders, and the outcome of tax, regulatory and regulatorylegal matters.

In the next 12 months, SCE expects to fund its obligations, capital expenditures, and dividendscash requirements through operating cash flows, tax benefits, and capital market and bank financings and equity contributions from Edison International Parent, as needed. SCE also has availability under its credit facilitiesfacility to fund liquiditycash requirements. SCE expects to issue bonds to finance or refinance eligible sustainable projects. For further information about eligible sustainable projects, see "Liquidity and Capital Resources—SCE" in the 2022 MD&A. SCE also expects to issue additional debt for general corporate purposes and to finance payments for future resolutions of claims related to the 2017/2018 Wildfire/Mudslide Events.

SCE has invested all $1.6 billion of the required AB 1054 Excluded Capital Expenditures. SCE issued securitized bonds in the amounts of $338 million, $533 million and $775 million in February 2021, February 2022 and April 2023, respectively, to finance these expenditures and related financing costs. SCE used the proceeds of the April 2023 securitized bonds to repay a term loan of $730 million prior to its maturity in May 2023.

In the first quarter of 2023, Moody's upgraded SCE's credit rating from Baa2 to Baa1 and revised SCE's rating outlook from positive to stable. In April 2023, Fitch upgraded SCE's credit rating from BBB- to BBB and revised SCE's rating outlook from positive to stable. The following tables summarizes SCE’s current long-term issuer credit ratings and outlook from the major credit rating agencies:

SCE's credit ratings may be affected if, among other things, regulators fail to successfully implement AB 1054 in a consistent and credit supportive manner or the Wildfire Insurance Fund is depleted by claims from catastrophic wildfires. Credit rating downgrades increase the cost and may impact the availability of short-term and long-term borrowings, including commercial paper, credit facilities, bond financings or other borrowings. In addition, some of SCE's power procurement contracts would

require SCE to pay related liabilities or post additional collateral if SCE's credit rating were to fall below investment grade. For further details, see "—Margin and Collateral Deposits."

The cost of capital adjustment mechanism set by the CPUC could impact SCE's results of operations and cash flows. The cost of capital adjustment mechanism's benchmark beginning January 1, 2023, is the 12-month, October 1, 2021 through September 30, 2017,2022, average Moody's Baa utility bond yield of 4.37%. If the difference between the benchmark and the average of the same index for the 12-month period from October 1, 2022 to September 30, 2023 exceeds 100-basis points, SCE's CPUC-authorized ROE will be adjusted for 2024 by half the amount of the difference (up or down). The average Moody's Baa utility bond yield between October 1, 2022 and April 25, 2023 was 5.72%. The spot rate for Moody's Baa utility bond was 5.42% on April 25, 2023. An average Moody's Baa utility bond yield of 4.94% or higher from April 26, 2023 through September 30, 2023 would trigger the mechanism to adjust upward. For further information see "Business—SCE— Overview of Ratemaking Process" in the 2022 Form 10-K.

Available Liquidity

At March 31, 2023, SCE had cash on hand of $690 million and approximately $2.15$2.5 billion available underto borrow on its $2.75$3.4 billion multi-year revolving credit facility. In addition, SCE issued debtThe credit facility is available for borrowing needs until May 2026 and preference stock in 2017.the aggregate maximum principal amount may be increased up to $4.0 billion, provided that additional lender commitments are obtained.

Regulatory Proceedings

Wildfire Related Regulatory Proceedings

In response to the increase in wildfire activity, and faster progression of and increased damage from wildfires across SCE's service territory and throughout California, SCE has incurred wildfire mitigation, wildfire insurance and wildfire and drought restoration related spending at levels significantly exceeding amounts authorized in SCE's GRCs.

Wildfire Expense Memorandum Account

SCE tracks insurance premium costs related to wildfire liability insurance policies as well as other wildfire-related costs in its WEMA. In December 2020, SCE filed a WEMA application with the CPUC to seek recovery of $215 million of costs recorded in WEMA at December 31, 2020. The costs are updatesprimarily related to incremental wildfire insurance premium expenses and associated costs for large transmission and substation projects sincewildfire liability insurance policies that provide coverage for the filinglast six months of the 2016 Form 10-K. SCE is currently evaluating the timing of its major construction projects. For further information on these projects, see "Liquidity and Capital Resources—SCE—Capital Investment Plan—Major Transmission Projects" in the year-end 2016 MD&A.

Major Transmission Projects
West of Devers
2020. In March 2017,2023, the CPUC issued a proposed decision denying ORA's September 2016 Applicationwhich, if approved, would authorize recovery of $207 million. The amount not approved in this decision relates to wildfire liability insurance coverage previously allocated to San Onofre, which SCE expects to be eligible for Rehearing regardingrecovery from the Westnuclear decommissioning trusts or from SCE customers in a future cost recovery proceeding.

CSRP

In March 2023, the CPUC approved SCE's second CSRP application to recover approximately $59 million of capital expenditures and $28 million of operation and maintenance expenses incurred from May 2021 to December 2021, resulting in a revenue requirement of $65 million. The decision also approved SCE seeking review and cost recovery of additional post-implementation CSRP costs incurred from January 2022 through December 2024 in its 2025 GRC filing.

ERRA Proceeding

In January 2023, as a result of undercollection in ERRA and PABA at the end of 2022 due to higher gas and power prices, SCE filed an expedited ERRA trigger application with the CPUC. In April 2023, the CPUC approved SCE to recover a revenue requirement of up to $596 million over 12 months beginning June 1, 2023. The decision also granted SCE authority to decline to place some or all of the increase into rates if its forecast reasonably demonstrates that it will not need some or all of the increase in order to bring its ERRA trigger balance within the prescribed threshold. See "Business—SCE—Overview of Ratemaking Process" in 2022 10-K for further information of ERRA trigger mechanism.

Major Transmission and Utility Owned Storage Projects

Eldorado-Lugo-Mohave Upgrade Project which sought additional project modifications and environmental mitigation measures. This action confirmed SCE's proposed project, which is

The total costs for the Eldorado-Lugo-Mohave Upgrade Project are expected to exceed amounts currently approved in the certificate of public convenience and necessity granted by the CPUC due to delays in regulatory approvals, contractor performance issues, COVID-19 and the availability of CAISO outage windows. Additional work may also be placedrequired to mitigate the impact of the project on nearby gas lines. SCE expects to request CPUC approval for the additional expenditures and expects the project to be in service in 2023. See "Liquidity—SCE—Capital Investment Plan" in 2022 10-K for further information.

Utility Owned Storage

As discussed in the 2022 Form 10-K, in October 2021, althoughSCE contracted with Ameresco, Inc. ("Ameresco") for the construction of utility owned energy storage projects at three sites in SCE's service territory with an aggregate capacity of 537.5 MW.

In April 2023, Ameresco discovered damage to some of the equipment at one of the projects which makes up 225 MW of the 537.5 MW aggregate capacity. SCE has received a notice of potential force majeure event from Ameresco noting that Ameresco is performing further analyses on the cause of the damage and asserting that rainstorms at the project site may have caused or contributed to the damage. SCE believes that there is potentialsignificant risk that this project will not be in-service to meet summer peak reliability needs.

Ameresco has advised SCE that it currently expects the other two projects to be in-service prior to August 2023.

Decommissioning of San Onofre

As discussed in the 2022 Form 10-K, in February 2022, SCE filed its application in the 2021 NDCTP with the CPUC requesting reasonableness review of approximately $570 million (SCE share in 2022 dollars) of recorded San Onofre Units 2 and 3 decommissioning costs incurred during the period 2018 to 2020. Intervenors in the proceeding have recommended approximately $115 million (SCE share in 2022 dollars) in disallowances for San Onofre Units 2 and 3 decommissioning costs. This amount includes a delay.recommended disallowance of approximately $45 million in costs associated with an August 2018 incident that occurred when an SCE is evaluating the competitive bids receivedcontractor was loading a spent nuclear fuel canister into an ISFSI resulting in fuel transfer operations being suspended for transmission construction and expects to award the contract for the Project by the end of 2017, which may result in a change to the expected costapproximately one year. The remainder of the Project.recommended disallowance amount is

Mesa Substation

In February 2017, the CPUC issued

primarily for contractor staffing costs incurred during a final decision approving the Mesa Substation Project largely consistent with SCE's proposed project and rejected alternative project configurations proposed by CPUC staff. SCE expects the Mesa Substation project to go into servicedelay in 2022. Competitive bids for the 220kV substation construction are under evaluation, and the remainder (550kV substation) will be put out for bid in 2018. SCE expects to award the bid for the 220kV substation construction by the end of 2017, which may result in a change to the expected cost. Preconstruction requirements for other permits and approvals have been obtained and construction began in October 2017.

Alberhill System
In April 2017, the CPUC issued a final environmental impact report for the Alberhill System Project. This report rejected different alternatives recommended by CPUC staff and intervenors, selecting SCE's proposed project as the environmentally superior project. A final CPUC decision to approve the Project for construction is anticipated during 2018. As SCE prepares for the commencement of construction, updated annual capital spending will be incorporated into the capital program forecast.
Riverside Transmission Reliability
The Riverside Transmission Reliability Project is a joint project between SCE and Riverside Public Utilities (RPU), the municipal utility departmentissuance of the City of Riverside. Due to changed circumstances since the time the Project was originally developed, SCE informed the CPUC in August 2016 that it supports revisions to the proposed Project. The CPUC continues to collect information regarding the revised Project or other proposed revisions in support of a supplemental environmental review. Impacts from the potential revisions to the Project have not been reflected in the expected costs or scheduled in-service date of 2021.
Eldorado-Lugo-Mohave Upgrade
The Eldorado-Lugo-Mohave Upgrade Project will increase capacity on existing transmission linesCDP to allow additional renewable energy to flow from Nevada to southern California. SCE has proposed an expedited schedule and a non-standard review process with the regulatory permitting agencies in order to meet the current in-service date. SCE recently awarded the competitive bid for the Project and has not yet incorporated the contract into the capital forecast.

Dividend Restrictions
The CPUC regulates SCE's capital structure which limits the dividends it may pay Edison International. SCE may make distributions to Edison International as long as the common equity component of SCE's capital structure remains at or above 48% on a 13-month weighted average basis. At September 30, 2017, SCE's 13-month weighted-average common equity component of total capitalization was 50.2% and the maximum additional dividend that SCE could pay to Edison International under this limitation was approximately $554 million, resulting in a restriction on net assets of approximately $14.4 billion.
In the third quarter of 2017, SCE declared a dividend to Edison International of $191 million. Future dividend amounts and timing of distributions are dependent on a number of factors including the level of capital expenditures, operating cash flows and earnings.

Margin and Collateral Deposits

Certain derivative instruments, power and energy procurement contracts and other contractual arrangements contain collateral requirements. In addition, certain environmental remediation obligations require financial assurance that may be in the form of collateral postings. Future collateral requirements may differ from the requirements at September 30, 2017,March 31, 2023, 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.

Someobligations, and the impact of the power 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 fallratings falling below investment grade, SCE may be required to pay the liability or post additional collateral.

In addition to amounts shown in the table, power and fuel contract counterparties may also institute new collateral requirements, applicable to future transactions to allow SCE to continue trading in power and fuel contracts at the time of a downgrade or upon significant increases in market prices. Furthermore, SCE may also be required to post up to $50 million in collateral in connection with its environmental remediation obligations, within 120 days of the end of the fiscal year in which the downgrade occurs.

Edison International Parent and Other

In the next 12 months, Edison International expects to fund its net cash requirements through cash on hand, dividends from SCE, and capital market and bank financings. Edison International may finance its ongoing cash requirements, including dividends, working capital requirements, payment of obligations, and capital investments, including capital contributions to subsidiaries, with short-term or other financings, subject to availability in the bank and capital markets.

At March 31, 2023, Edison International Parent and Other had cash on hand of $146 million and $878 million available to borrow on its $1.5 billion revolving credit facility. The credit facility is available for borrowing needs until May 2026 and the aggregate maximum principal amount may be increased up to $2.0 billion, provided that additional lender commitments are obtained. For further information, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

13

In March 2023, Edison International Parent issued $500 million of junior subordinated notes, due in 2053, which provide approximately $250 million of equity content as viewed by rating agencies. Edison International expects to raise any additional equity this year through its internal programs, which are estimated to generate approximately $100 million. The total expected equity content is consistent with the $300 million to $400 million of equity content identified in Edison International's 2023 financing plan.

Edison International Parent and Other's liquidity and its ability to pay operating expenses and pay dividends to preferred and common shareholders are dependent on access to the bank and capital markets, dividends from SCE, realization of tax benefits and accessits ability to bankmeet California law requirements for the declaration of dividends. Prior to declaring dividends, Edison International's Board of Directors evaluates available information to ensure that the California law requirements for the declarations are met. For information on the California law requirements on the declaration of dividends, see "Liquidity and capital markets.Capital Resources—SCE—SCE Dividends" in the 2022 Form 10-K. Edison International may also finance working capital requirements, paymentintends to maintain its target payout ratio of obligations, and capital investments, including capital contributions to subsidiaries, with commercial paper or other borrowings,45% – 55% of SCE's core earnings, subject to availability in the bankfactors identified above.

At September 30, 2017, Edison International Parent had $677 million availablepay common dividends may be restricted under the terms of its $1.25 billion multi-year revolving credit facility. In addition, Edison International issued debt in 2017.Series A and Series B Preferred Stock. For further details,information, see "Notes"Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

Edison International Parent's credit facility requires a consolidated debt to total capitalization ratio as defined in the credit agreementapplicable agreements of less than or equal to 0.650.70 to 1. At September 30, 2017,March 31, 2023, Edison International Parent'sInternational's consolidated debt to total capitalization ratio was 0.470.64 to 1.

At September 30, 2017,March 31, 2023, Edison International Parent was also in compliance with all other financial covenants that affect access to capital.

In the first quarter of 2023, Moody's upgraded Edison International's credit rating from Baa3 to Baa2 and revised Edison International's rating outlook from positive to stable. In April 2023, Fitch upgraded Edison International's credit rating from BBB- to BBB and revised Edison International's rating outlook from positive to stable The following table summarizes Edison International Parent's current long-term issuer credit ratings and outlook from the major credit rating agencies:

Edison International Parent's credit ratings may be affected if, among other things, regulators fail to successfully implement AB 1054 in a consistent and credit supportive manner or the Wildfire Insurance Fund is depleted by claims from catastrophic wildfires. Credit rating downgrades increase the cost and may impact the availability of short-term and long-term borrowings, including commercial paper, credit facilities, note financings or other borrowings.


Edison International Income Taxes

Inflation Reduction Act of 2022

On August 16, 2022, the IRA was signed into law. The law imposes a 15% corporate alternative minimum tax ("CAMT") on adjusted financial statement income ("AFSI") of corporations with average AFSI exceeding $1 billion over a specified 3-year period. The CAMT was effective beginning January 1, 2023. Based on the current interpretation of the law and historical financial data, Edison International estimates that it will exceed the $1 billion threshold and be subject to CAMT on its consolidated Federal tax returns beginning in 2025. SCE expects to be subject to CAMT on its stand-alone Federal return beginning in 2024.

The law also includes significant extensions, expansions, and enhancements of numerous energy-related investment tax credits, as well as creating new credits applicable to electricity production which may apply to SCE's capital expenditures.


14

Under the IRA, SCE expects to generate investment tax credits related to its utility owned storage projects, which will accrue to the benefit of its customers.

Net cash (used in) provided by operating activities was impacted by the following:

Net income and non-cash items increased in 20172023 by $75$334 million primarily due to higher revenue in 2017 due to thefrom escalation mechanism set forth in the 20152021 GRC final decision, and lower operation and maintenance expenses, partially offset by reductionshigher net interest expense.

Net changes in CPUC revenue related to prior overcollectionscash resulting from working capital was an outflow of $725 million and higher financing costs.

an inflow of $78 million during the three months ended March 31, 2023 and 2022, respectively. Net cash outflow for working capital for the nine months ended September 30, 2017 and 20162023 was primarily relateddue to the increase in receivables from customers ($370 million and $261 million in 2017 and 2016, respectively) and the timing of disbursements (including payments for payroll-related costs and purchased power). During the first nine months of 2017, there was an increasedecreases in payables of $30$695 million comparedmainly from payments of power purchase contracts driven by a decrease in gas prices from December 2022, and $171 million cash outflow for margin and collateral deposits due to $195 millionthe decrease in the market value of power and gas derivatives, partially offset by inflow from net decreases in customer receivables and unbilled revenue of $113 million. Net cash inflow for the same period in 2016. In addition, net cash for working capital included changes in tax payables of $(146) million in 2017 and $111 million in 20162022 was primarily due to the utilizationa net decrease in customer receivables and unbilled revenue of

prepaid insurance of $88 million, partially offset by a decrease in payables of $166 million.

Net cash (used in) provided by regulatory assets and liabilities, including changes in over (under) collections ofnet undercollections recorded in balancing accounts, was $560$(296) million and $189$259 million during the ninethree months ended September 30, 2017March 31, 2023 and 2016,2022, respectively. SCE has a number of balancing and memorandum accounts, which impact cash flows based on differences between timing of collection of amounts through rates and accrual expenditures. Cash flows were primarily impacted by the following:

2023

Decreased overcollections of $234 million for GHG revenue related to climate credits provided to customers, partially offset by GHG revenue related to GHG auction revenue received.
Undercollections of wildfire related memorandum and balancing accounts increased by $106 million primarily due to additional wildfire risk mitigation and restoration costs incurred.
Net undercollections of BRRBA increased by $26 million primarily due to lower sales volume in 2023, partially offset by recovery of prior year undercollections from various tracks of the 2021 GRC.
Net undercollections for ERRA, PABA and NSGBA decreased by $14 million primarily due to recovery of prior PABA undercollections, partially offset by current year undercollections due to lower than forecast sale volume.

2022

Net undercollections of BRRBA increased by $511 million primarily due to $401 million of expense authorized under GRC track 2 for collection in customer rates starting March 2022 over a 36-month period, and current year undercollections due to actual billed prices lower than forecast due to timing, partially offset by recovery of prior year undercollections, including 2021 GRC authorized additional revenue requirement for the first nine months of 2021 to be collected over a 27-month period starting October 2021.
Undercollections decreased by $371 million related to wildfire risk mitigation memorandum and balancing accounts as a result of approval to recover costs in GRC track 2, which were transferred to BRRBA for recovery as mentioned above, partially offset by additional wildfire risk mitigation costs incurred.
Net undercollections for ERRA, PABA and NSGBA decreased by $72 million primarily due to recovery of prior PABA and NSGBA undercollections, partially offset by current year undercollections due to delay in rate change and higher market exposure.
Increased overcollections of $221 million for the public purpose and energy efficiency programs as a result of lower program spending due to timing.
Increase in overcollection of $144 million for excess California Department of Water Resources ("DWR") bond and power charges to berefunded to customers over a 12-month period beginning in June 2022.

The 2015 GRC decision established the TAMA. As a result
Higher cash due to $186 million of overcollections for the public purpose and energy efficiency programs. Overcollections for public purpose and energy efficiency programs increased due to lower spending for these programs and recovery of prior year undercollections.
Higher cash due to $140 million of overcollections related to FERC balancing accounts. Overcollections increased due to recovery of prior FERC undercollections and lower costs than forecasted in the FERC formula rate.
Higher cash due to $94 million of overcollections related to the timing of greenhouse gas auction revenue and climate credit refunds to customers, which are expected to be refunded to customers in the fourth quarter of 2017.
Higher cash due to realization of $47 million in proceeds from the MHI arbitration and approximately $34 million from the Department of Energy related to spent nuclear fuel. For further information on the MHI claims and spent nuclear fuel, see "Notes to Consolidated Financial Statements—Note 11. Commitments and Contingencies—Contingencies—San Onofre Related Matters" and "—Spent Nuclear Fuel."
BRRBA overcollections decreased by $161 million during the first nine months of 2017 primarily due to the refunds of 2016 overcollections related to TAMA, a revenue refund to customers of $133 million for 2012 – 2014 incremental tax benefits related to repair deductions, and 2015 overcollections resulting from the implementation of the 2015 GRC decision, which was authorized to be refunded to customers over a two year period. The BRRBA tracks the differences between amounts authorized by the CPUC in the GRC proceedings and amounts billed to customers.
Net undercollections for ERRA and the new system generation program were $91 million at September 30, 2017 compared to net overcollections of $26 million at December 31, 2016. Net undercollections increased $117 million during the first nine months of 2017 primarily due to a refund of prior year overcollections and an increase in costs due to higher load requirements than forecasted in rates.
2016
Higher cash due to an increase in overcollections of $300 million for the public purpose and energy efficiency programs due to higher funding and lower spending for these programs during the first nine months of 2016.
ERRA overcollections for fuel and purchased power decreased by $231 million during the first nine months of 2016 primarily due to the implementation of the 2016 ERRA rate decrease in January 2016, partially offset by lower than forecasted power and gas prices experienced in 2016.
An increase in cash of approximately $122 million due to a refund from the Department of Energy's failure to meet its obligation to begin accepting spent nuclear fuel from San Onofre. See "Notes to Consolidated Financial Statements—Note 11. Commitments and Contingencies—Contingencies—Spent Nuclear Fuel" for further discussion.
Cash flows used in other noncurrent assets and liabilities were primarily related to net earnings from nuclear decommissioning trust investments ($47 million and $33 million in 2017 and 2016, respectively), SCE's payments of decommissioning costs ($170 million and $125 million in 2017 and 2016, respectively) and changes in uncertain tax positions due to the utilization of net operating losses ($(105) million and $(4) million in 2017 and 2016, respectively). See "Nuclear Decommissioning Activities" below for further discussion.

Contingencies

SCE has contingencies related to San Onofre Related Matters, Environmental Remediation, Nuclear Insurance, Wildfire Insurance, Spent Nuclear Fuel

Edison International's and other legal matters, whichSCE's contingencies are discussed in "Notes to Consolidated Financial Statements—Note 11.12. Commitments and Contingencies—Contingencies."

MARKET RISK EXPOSURES

Edison International's and SCE's primary market risks are described in the 20162022 Form 10-K.10-K, and there have been no material changes for the three months ended March 31, 2023. For a further discussion of market risk exposures, including commodity price risk credit risk, and interest ratecredit risk, see "Notes to Consolidated Financial Statements—Note 4. Fair Value Measurements" and "—Note 6. Derivative Instruments."



Commodity Price Risk
The fair value of outstanding derivative instruments used to mitigate exposure to commodity price risk was a net liability of $1.1 billion at December 31, 2016. During the third quarter of 2017, SCE designated certain derivative contracts as normal purchase and normal sale contracts, which resulted in a reclassification of $914 million from derivative liabilities to other liabilities. These liabilities will be amortized over the remaining contract terms. The fair value of the remaining derivative instruments at September 30, 2017 was $35 million.
For further discussion of fair value measurements and the fair value hierarchy, see "Notes to Consolidated Financial Statements—Note 4. Fair Value Measurements" and "— Note 6. Derivative Instruments."
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, 2017, the amount of balance sheet exposure as described above broken down by the credit ratings of SCE's counterparties, was as follows:
 September 30, 2017
(in millions)
Exposure2
 Collateral Net Exposure
S&P Credit Rating1
     
A or higher$38
 $
 $38
1
SCE assigns a credit rating based on the lower of a counterparty's S&P, Fitch 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 three 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.

Allowance for Uncollectible Accounts

The allowance for uncollectible accounts is recorded based on SCE's estimate of each year. Edison International updates these tests between annual tests if events occur or circumstances change such that it is more likely than not thatexpected credit losses and adjusted over the fair value of a reporting unit is below its carrying value. In connection with a strategic reviewlife of the Edison Energy Group's competitive businesses, Edison International evaluatedreceivables as needed. Since the recoverabilitycustomer base of goodwillSCE is concentrated in Southern California and recorded an impairmentexposes SCE to a homogeneous set of SoCore Energy's goodwill totaling $16.5 million ($10 million after-tax)economic conditions, the allowance is measured on a collective basis on the historical amounts written-off, assessment of customer collectibility and current economic trends, including unemployment rates and any likelihood of recession for the region.

The following table sets forth the changes in the second quarter of 2017. As of September 30, 2017, goodwill is comprised of $78 million at the Edison Energy reporting unit and $5 million at the SoCore Energy reporting unit.allowance for uncollectible accounts for SCE:

Earnings Per Share

Edison International computes earnings per common 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 performance shares and restricted stock units, which earn dividend equivalents on an equal basis with common shares once the awards are vested. See Note 13 for further information.

For such arrangements, revenue from contracts withThis typically occurs when electricity is delivered to customers, will be equivalent towhich includes amounts for services rendered but unbilled at the electricity supplied and billed in that period (including estimated billings). As such, there will not beend of a change in the timing or pattern of revenue recognition for such sales. Edison International andreporting period.

Regulatory Proceedings

FERC 2023 Formula Rate Update

In November 2022, SCE are in the process of implementing the system and process changes necessary to comply with this standard's enhanced disclosure requirements. Edison International and SCE plan to disaggregate customer contract revenue between revenue from earnings activities and revenue from cost-recovery activities. Some revenue arrangements, such as alternative revenue programs which include balancing account over- and under-collections, are excluded from the scope of the new standard and, therefore, will be accounted for and presented separately from revenues recognized under the new standard on the Edison International and SCE consolidated financial statements. Edison International and SCE will adopt the standard by using the modified retrospective method by recognizing a cumulative effect adjustment to the opening balance of retained earnings on January 1, 2018. Edison International and SCE do not expect the cumulative effect adjustment to be material.

In January 2016, the FASB issued an accounting standardsfiled its 2023 annual update that amends the guidance on the classification and measurement of financial instruments. The amendments require equity investments (excluding those accounted for under the equity method or those that result in consolidation) to be measured at fair value, with changes in fair value recognized in net income. It also amends certain disclosure requirements associated with the fair value of financial instruments. In addition,FERC with the new guidance requires financial assets and financial liabilities to be presented separately in the notes to the financial statements, grouped by measurement category and form of financial asset. Edison International and SCE will adopt this guidanceproposed rates effective January 1, 2018. SCE's nuclear decommissioning trust investments contain equity investments that are classified as available-for-sale. Due2023, subject to regulatory mechanisms,settlement procedures and refund. Pending resolution of the changeFERC formula rate proceedings, SCE recognized revenue in fair valuethe first quarter of these investments has no impact on net income and, therefore, the adoption of this standard is not expected to have a material impact on Edison International's and SCE's consolidated financial statements.
In February 2016, the FASB issued an accounting standards update related to lease accounting including enhanced disclosures. Under the new standard, a lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified assets for a period of time in exchange for consideration. Lessees will need to recognize leases on the balance sheet as a right-of-use asset and a related lease liability, and classify the leases as either operating or finance. The liability will be equal to the present value of lease payments. The asset will be2023 based on the liability,FERC 2023 annual update rate, subject to adjustment, such as for initial direct costs. Operating leases will result in straight-line expense while finance leases will result in a higher initial expense pattern due to the interest component. SCE, as a regulated entity, is permitted to continue to have straight-line expense for finance leases, assuming the rate recovery is based upon current payments. Lessees can elect to exclude from the balance sheet short-term contracts one year or less. This guidance is effective January 1, 2019. Early adoption is permitted, but Edison International and SCE do not expect to elect early adoption. The adoptionrefund.

31

Table of this standard will increase right-of-use assets and lease liabilities in Edison International's and SCE's consolidated balance sheets. Edison International and SCE are currently evaluating the impact this standard will have on the results of operations and statements of cash flows and lease disclosures.

The FASB also issued an accounting standards update related to the impairment of financial instruments, effective January 1, 2020. The new guidance provides an impairment model, known as the current expected credit loss model, which is based on expected credit losses rather than incurred losses. Edison International and SCE are currently evaluating the impact of this new guidance.


The FASB also issued accounting standards updates related to the presentation and classification of certain cash receipts and payments in the statement of cash flows, including a change to the amount of cash, cash equivalents, and restricted cash explained when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. These standards are effective January 1, 2018 and require retrospective application. Restricted cash as of September 30, 2017 was $15 million at Edison International and was less than $1 million at SCE.
In January 2017, the FASB issued an accounting standards update to simplify the accounting for goodwill impairment. This accounting standards update changes the procedural steps in applying the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Edison International will apply this guidance to the goodwill impairment test beginning in 2020.
In March 2017, the FASB issued an accounting standards update which amends the current requirements related to the presentation of the components of net periodic benefit cost for an entity's defined benefit pension and other postretirement plans. The adoption of this standard is not expected to have a material impact on Edison International's and SCE's financial position or results of operations, but will result in the separate presentation of service costs as an operating expense and non-service costs within other income and expense and limit the capitalization of benefit costs to the service cost component. During the three and nine months ended September 30, 2017, service costs totaled $45 million and $135 million, respectively, for Edison International and $44 million and $132 million, respectively, for SCE. During the three and nine months ended September 30, 2017, non-service costs were $(14) million and $(32) million, respectively, for Edison International and $(15) million and $(45) million, respectively, for SCE. The new standards update is effective on January 1, 2018. It is required to be applied on a retrospective basis for the presentation of the service cost component and the other components of net benefit cost and on a prospective basis for the capitalization of only the service cost component of net benefit cost.Contents

Note 3.Variable Interest Entities

A VIE is defined as a legal entity that meets one of two conditions: (1) the equity owners do not have sufficient equity at risk, or (2) the holders of the equity investment at risk, as a group, lack any of the following three characteristics: decision-making rights, the obligation to absorb losses or the right to receive the expected residual returns of the entity. The primary beneficiary is identified as the variable interest holder that has both the power to direct the activities of the VIE that most significantly impact the entity's economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. The primary beneficiary is required to consolidate the VIE. A subsidiary of Edison International is the primary beneficiary of entities that own rooftop solar projects. Commercial and operating activities are generally the factors that most significantly impact the economic performance of such VIEs. Commercial and operating activities include construction, operation and maintenance, fuel procurement, dispatch and compliance with regulatory and contractual requirements.

Variable Interest in VIEs that are Consolidated

SCE Recovery Funding LLC is a bankruptcy remote, wholly owned special purpose subsidiary, consolidated by SCE. SCE Recovery Funding LLC is a VIE and SCE is the primary beneficiary. SCE Recovery Funding LLC was formed in 2021 for the purpose of issuing and servicing securitized bonds related to SCE's AB 1054 Excluded Capital Expenditures.

33

Table of Contents

In 2022 and 2021, SCE Recovery Funding LLC issued a total of $871 million of securitized bonds and used the proceeds to acquire SCE's right, title and interest in and to non-bypassable rates and other charges to be collected from certain existing and future customers in SCE's service territory, associated with the AB 1054 Excluded Capital Expenditures ("Recovery Property"), until the bonds are paid in full, and all financing costs have been recovered. The securitized bonds are secured by the Recovery Property and cash collections from the non-bypassable rates and other charges are the sole source of funds to satisfy the debt obligation. The bondholders have no recourse to SCE. In April 2023, SCE Recovery Funding LLC issued $775 million of securitized bonds. For further details, see Note 5.

Variable Interest in VIEs that are not Consolidated

Power Purchase Agreements

SCE has power purchase agreements ("PPAs")PPAs that are classified as variable interests in VIEs, including tolling agreements through which SCE provides the natural gas to fuel the plants, fixed price contracts for renewable energy, and contracts with qualifying facilitiesresource adequacy agreements that, contain variable pricing provisions based onupon the priceseller's election, include the purchase of natural gas.energy at fixed prices. 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. Since 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 that are not consolidated result from amounts due under the PPAs. Under these contracts, SCE recovers the costs incurred through demonstration of compliance with its California Public Utilities Commission ("CPUC")-approvedCPUC-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 1112 of the 20162022 Form 10-K. As a result, there is no significant potential exposure to loss to SCE from its variable interest in these VIEs. The aggregate contracted capacity dedicated to SCE from these VIE projects was 4,8583,844 MW and 4,3493,645 MW at September 30, 2017March 31, 2023 and 2016,2022, respectively, and the amounts that SCE paid to these projects were $325$170 million and $313$106 million for the three months ended September 30, 2017March 31, 2023 and 2016, respectively, and $571 million and $532 million for nine months ended September 30, 2017 and 2016,2022, respectively. These amounts are recoverable in customer rates, subject to reasonableness review.



Unconsolidated Trusts of SCE

SCE Trust I, Trust II, Trust III, Trust IV, Trust V, and Trust VI were formed in 2012, 2013, 2014, 2015, 2016, and 2017, respectively, for the exclusive purpose of issuing the 5.625%, 5.10%, 5.75%, 5.375%, 5.45%, and 5.00% trust preference securities, respectively ("trust securities"). The trusts are VIEs. SCE has concluded that it is not the primary beneficiary of these VIEs as it does not have the obligation to absorb the expected losses or the right to receive the expected residual returns of the trusts. SCE Trust I, Trust II, Trust III, Trust IV, Trust V and Trust VI issued to the public trust securities in the face amounts of $475 million, $400 million, $275

Table of Contents

$275 million, $325 million, $300 million, and $475 million (cumulative, liquidation amounts of $25 per share), respectively, and $10,000 of common stock each to SCE. The trusts invested the proceeds of these trust securities in Series F, Series G, Series H, Series J, Series K, and Series L Preference Stock issued by SCE in the principal amounts of $475 million, $400 million, $275 million, $325 million, $300 million, and $475 million (cumulative, $2,500 per share liquidation values), respectively, which have substantially the same payment terms as the respective trust securities.

The Series F, Series G, Series H, Series J, Series K, and Series L Preference Stock and the corresponding trust securities do not have a maturity date. Upon any redemption of any shares of the Series F, Series G, Series H, Series J, Series K, or Series L Preference Stock, a corresponding dollar amount of trust securities will be redeemed by the applicable trust. The applicable trust will make distributions at the same rate and on the same dates on the applicable series of trust securities if and when the SCE board of directors declares and makes dividend payments on the related Preference Stock. The applicable trust will use any dividends it receives on the related Preference Stock to make its corresponding distributions on the applicable series of trust securities. If SCE does not make a dividend payment to any of these trusts, SCE would be prohibited from paying dividends on its common stock. SCE has fully and unconditionally guaranteed the payment of the trust securities and trust distributions, if and when SCE pays dividends on the related Preference Stock.

In July 2017, SCE Trust I redeemed $475 million of trust securities from the public and $10,000 of common stock from SCE. As a result in September 2017, SCE Trust I was terminated.

The Trust II, Trust III, Trust IV, Trust V and Trust VVI balance sheets as of September 30, 2017March 31, 2023 and December 31, 2016,2022 consisted of investments of $400$220 million, $275 million, $325 million, $300 million, and $300$475 million in the Series G, Series H, Series J, Series K and Series KL Preference Stock, respectively, $400$220 million, $275 million, $325 million, $300 million, and $300$475 million of trust securities, respectively, and $10,000 each of common stock. The Trust VI balance sheet as of September 30, 2017 consisted of investments of $475 million in the Series L Preference Stock, $475 million of trust securities, and $10,000 of common stock.

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. As of September 30, 2017March 31, 2023 and December 31, 2016,2022, nonperformance risk was not material for Edison International and SCE.

Assets and liabilities are categorized into a three-level fair value hierarchy based on valuation inputs used to determine fair value.

Level 1 – The fair value of Edison International's and SCE's 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, U.S. treasury securities, mutual funds, and money market funds.

Level 2 – Edison International's and SCE's Level 2 assets and liabilities include fixed income securities, primarily consisting of U.S. government and agency bonds, municipal bonds and corporate bonds, and over-the-counter derivatives. The fair value of fixed income securities is determined using a market 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.

The fair value of SCE's over-the-counter derivative contracts is determined using an income approach. SCE uses 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 Intercontinentalan exchange (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 SCE's Level 3 assets and liabilities is determined using the income approach through various models and techniques that require significant unobservable inputs. This level includes derivative contracts that trade infrequently such as congestion revenue rights ("CRRs"). Edison International Parent and Other does not have any Level 3 assets and liabilities.

Assumptions are made in order to value derivative contracts in which observable inputs are not available. 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. See Note 6 for a discussion of derivative instruments.

During the third quarter of 2017, SCE designated certain derivative contracts as normal purchase and normal sale contracts, which resulted in a reclassification of $914 million from derivative liabilities to other liabilities. These liabilities will be amortized over the remaining contract terms.
Edison International and SCE recognize the fair value for transfers in and transfers out of each level at the end of each reporting period. There were no material transfers between any levels during 2017 and 2016.
Valuation Techniques Used to Determine Fair Value
The process of determining fair value is the responsibility of SCE's risk management department, which reports to SCE's chief financial officer. This department obtains 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.

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. There are no securities classified as Level 3 in the nuclear decommissioning trusts.

Edison International Parent and Other

Edison International Parent and Other assets measured at fair value and classified as Level 1 consisted of equity investments of $2 million and $5 million and money market funds of $136 million and $137 million at March 31, 2023 and December 31, 2022, respectively. Assets measured at fair value and classified as Level 2 consisted of short-term investments of $1 million and $2 million at March 31, 2023 and December 31, 2022, respectively. There are no securities classified as Level 3 for Edison International Parent and Other.

Note 5.Debt and Credit Agreements

Long-Term Debt

During the first quarter of 2017,

In March 2023, SCE borrowed $300 million under a Term Loan Agreement due July 2018, with a variable interest rate based on the London Interbank Offered Rate plus 65 basis points. The proceeds were used for general corporate purposes.

During the first quarter of 2017, SCE reissued $135issued $750 million of 2.625% pollution-control bonds subject to mandatory remarketing in December 2023. The proceeds were used for general corporate purposes.
During the first quarter of 2017 and in September 2017, SCE issued $700 million and $300 million, respectively, of 4.00%5.30% first and refunding mortgage bonds due in 2047.2028. The aggregate principal amount of these bonds totaled $1.0 billion and the proceeds from the first quarter issuance were used to repay commercial paper borrowings, to fund SCE's capital program and for general corporate purposes. The proceeds from the September 2017 issuance were used to repaypayment of wildfire claims above the $300 million Term Loan Agreement discussed above.
During the first quarteramount of 2017, Edison Internationalexpected insurance proceeds. SCE also issued $400$450 million of 2.125% senior notes5.70% first and refunding mortgage bonds due in 2020.2053. The proceeds were used to repay commercial paper borrowings and for general corporate purposes.

In August 2017,March 2023, Edison International Parent issued $400$500 million of 2.40% senior8.125% junior subordinated notes due in 2022. In September 2017,2053, with interest rate resets every five years at a rate equal to the Five-year U.S. Treasury rate plus a spread of 3.864%. The proceeds from the August 2017 issuance were used to repay $400 million of Edison International's 3.75% senior notes.

Project Financings
In October 2017, indirect subsidiaries of Edison Energy Group entered into approximately $100 million in non-recourse debt and tax equity financings to support investments in ground mount solar projects. The tax equity investor in these solar projects will receive an initial allocation of 99% of taxable losses and tax credits, followed by 67% of taxable income and losses after the initial period and 15.6% of cash flows until certain conditions are met, including attaining a specified rate of return.  A subsidiary of Edison Energy Group has the option after certain conditions are met to purchase the tax equity investor's interest at the higher of fair value or the after-tax amount necessary to achieve a specified 20-year rate of return.
Credit Agreements and Short-Term Debt
SCE and Edison International Parent have multi-year revolving credit facilities of $2.75 billion and $1.25 billion, respectively. During the third quarter of 2017, SCE and Edison International Parent extended the maturity date to July 2022. SCE's credit facility is generally used to support commercial paper borrowings 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. Edison International Parent's credit facility is used to support commercial paper borrowings and for general corporate purposes.

Note 6.Derivative Instruments

Derivative financial instruments are used to manage exposure to commodity price risk. These risks are managed in part by entering into forward commodity transactions, including options, swaps and futures. To mitigate credit risk from counterparties in the event of nonperformance, master netting agreements are used whenever possible, and counterparties may be required to pledge collateral depending on the creditworthiness of each counterparty and the risk associated with the transaction.

Commodity Price Risk

Commodity price risk represents the potential impact that can be caused by a change in the market value of a particular commodity. 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 PPAs. SCE's natural gas price exposure arises from natural gas purchased for the Mountainview power plantplants, Peaker plants and peaker plants, qualifying facilityQualifying Facilities contracts where pricing is based on a monthly natural gas index and PPAs in which SCE has agreed to provide the natural gas needed for generation, referred to as tolling arrangements.

Credit and Default Risk

Credit and default risk represent the potential impact that can be caused if a counterparty were to default on its contractual obligations and SCE would be exposed to 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 the sales of excess power and realized gains on derivative instruments.

39

Certain power and gas contracts contain master netting agreements or similar agreements, which generally allow counterparties subject to the agreement to offset amounts when certain criteria are met, such as in the event of default. The objective of netting is to reduce credit exposure. Additionally, to reduce SCE's risk exposures, counterparties may be required to pledge collateral depending on the creditworthiness of each counterparty and the risk associated with the transaction.

Certain power and gas contracts contain a provision that requires SCE to maintain an investment grade rating from each of the major credit rating agencies that have credit ratings for SCE, 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 post additional collateral to cover derivative liabilities and the related outstanding payables. The net fair value of all derivative liabilities with these credit-risk-related contingent features was $2 million and $12less than $1 million as of September 30, 2017March 31, 2023 and December 31, 2016, respectively,2022, for which SCE has posted $15no collateral and collateral of $24 million and $12 million collateral at September 30, 2017 and December 31, 2016, respectively, to its counterparties for its derivative liabilities and related outstanding payables.payables as of March 31, 2023 and December 31, 2022, respectively. If the credit-risk-related contingent features underlying these agreements were triggered on September 30, 2017,March 31, 2023, SCE would be required to post $15$2 million of additional collateral, most of which $13 million is related to outstanding payables that are net of collateral already posted.

payables.

Fair Value of Derivative Instruments

SCE presents its derivative assets and liabilities on a net basis on its consolidated balance sheets when subject to master netting agreements or similar agreements. Derivative positions are also offset against margin and cash collateral deposits. In addition, SCE has provided collateral in the form of letters of credit. Collateral requirements can vary depending upon the level of unsecured credit extended by counterparties, changes in market prices relative to contractual commitments and other factors. See Note 4 for a discussion of fair value of derivative instruments. The following table summarizes the gross and net fair values of SCE's commodity derivative instruments:

Financial 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 purchased 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 remaining effects of derivative activities and related regulatory offsets are recordedreported in cash flows from operating activities in theSCE’s consolidated statements of cash flows.

Note 7.Revenue

SCE's revenue is disaggregated by two revenue sources:

Earning activities – representing revenue authorized by the CPUC and FERC, which is intended to provide SCE with 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 earnings activities are revenue or penalties related to incentive mechanisms, other operating revenue, and regulatory charges or disallowances.
Cost-recovery activities – representing CPUC- and FERC- authorized balancing accounts, which allow for recovery of specific project or program costs, subject to a reasonableness review or compliance with upfront standards, as well as non-bypassable rates collected for SCE Recovery Funding LLC. Cost-recovery activities include rates which provide recovery, subject to a reasonableness review of, among other things, fuel costs, purchased power costs, public purpose related-program costs (including energy efficiency and demand-side management programs), certain operation and maintenance expenses and repayment of bonds and financing costs of SCE Recovery Funding LLC. SCE earns no return on these activities.

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. Flow-through items reduce current authorized revenue requirements in SCE's rate cases and result in a regulatory asset for recovery of deferred income taxes in future periods. The difference between the authorized amounts as determined in SCE's rate cases, adjusted for balancing and memorandum account activities, and the recorded flow-through items also result in increases or decreases in regulatory assets with a corresponding impact on the effective tax rate to the extent that recorded deferred amounts are expected to be recovered in future rates. For further information, see Note 10.11.

In March 2017, SCE received the final decision on claims against, and counterclaims of, Mitsubishi Heavy Industries, Inc. and related companies (together, "MHI") from the arbitration tribunal, the International Chamber of Commerce, discussed further in Note 11. San Onofre was permanently shut down on June 7, 2013 as a result of failure of replacement steam generators supplied by MHI. With the resolution of the insurance claim against Nuclear Electric Insurance Limited ("NEIL") in October 2015 and the conclusion of the arbitration proceeding against MHI, a tax abandonment loss of $691 million and $1.13 billion for federal and state income tax purposes, respectively, was claimed in the first six months of 2017, resulting in a flow-through tax benefit of approximately $39 million impacting the effective tax rate. Due to the tax abandonment loss recognized during the first nine months of 2017, Edison International and SCE both expect to report federal and California tax losses in 2017.
Unrecognized Tax Benefits
In the first quarter of 2017, Edison International settled all open tax positions with the Internal Revenue Service ("IRS") for taxable years 2007 through 2012. The following table provides a reconciliation of unrecognized tax benefits for 2017 as a result of the audit settlement:

Tax Disputes

In the first quarter of 2017, Edison International settled all open tax positions with the IRS for taxable years 2007 through 2012. Edison International has previously made cash deposits to cover the estimated tax and interest liability from this audit cycle and expects a $7 million refund of this deposited amount.

Tax years that remain open for examination by the IRS and the California Franchise Tax Board ("FTB") are 2014201920162022 and 201020132016,2022, respectively. Edison International has settled all open tax position with the IRS for taxable years prior to 2013. 

Tax years 1994 – 2006 are currently in settlement negotiations with the California Franchise Tax Board. While we expect to resolve these tax years within the next twelve months, the impacts cannot be reasonably estimated until further progress has been made. Tax years 2007 – 2009 are currently under protest with the California Franchise Tax Board.

Note 8.    9.Compensation and Benefit Plans

Pension Plans

Edison International made contributions of $100 million during the nine months ended September 30, 2017, which includes contributions of $64 million by SCE. Edison International expects to make contributions of $15 million during the remainder of 2017, which includes $1 million from SCE. Annual contributions made by SCE to most of SCE's pension plans are anticipated to be recovered through CPUC-approved regulatory mechanisms.

Postretirement Benefits Other Than Pensions

Edison International made contributions of $16 million during the nine months ended September 30, 2017 and expects to make contributions of $5 million during the remainder of 2017, substantially all of which are expected to be made by SCE. Annual contributions related to SCE employees made to SCE plans are anticipated to be recovered through CPUC-approved regulatory mechanisms and 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. Under the terms of the Edison International Health and Welfare Plan ("PBOP Plan"PBOP") each participating employer (Edison International or its participating subsidiaries) is responsible for the costs and expenses of all PBOP Plan benefits with respect to its employees and former employees. A participating employer may terminate the PBOP Plan benefits with respect to its employees and former employees, as may SCE (as PBOP Plan sponsor), and, accordingly, the participants' PBOP Plan benefits are not vested benefits.

Edison International Parent and Other's Investments

Edison International Parent and Other hold strategic investments in companies focused on operating revenue or earnings.developing electric technologies and services. As of March 31, 2023 and December 31, 2022, these investments consist of $2 million and $5 million of marketable securities, respectively, and $12 million of equity investments without readily determinable fair values (included as "Other investments" on Edison International's consolidated balance sheets) at both dates. For further information of fair value of marketable securities, see Note 4. The equity investments without readily determinable fair values balances included cumulative upward adjustments of $9 million at both March 31, 2023 and December 31, 2022. The cumulative upward adjustments resulted primarily from values determined by additional capital infusions.

Note 11.12. Commitments and Contingencies

Third-Party Power Purchase Agreements
During the first nine months of 2017, SCE had existing PPAs that met the critical contract provisions (including completion of major milestones for construction). SCE's net additional commitments for power purchase agreements are estimated to be: $27 million in 2018, $72 million in 2019, $62 million in 2020, $20 million in 2021, and $1.2 billion for the remaining period thereafter. For further information, see Note 11 in the 2016 Form 10-K.

Indemnities

Edison International and SCE have various financial and performance guarantees and indemnity agreements which are issued in the normal course of business.

Edison International and SCE have providedagreed to provide 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.sold or other contractual arrangements. Edison International's and SCE's obligations under these agreements may or may not be limited in terms of time and/or amount, and in some instances Edison International and SCE may have recourse against third parties. Edison International and SCE have not recorded a liability related to these indemnities. The overall maximum amount of the obligations under these indemnifications cannot be reasonably estimated.

SCE has indemnified the City of Redlands, California in connection with the Mountainview power plant'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.

Contingencies

In addition to the matters disclosed in these Notes, Edison International and SCE are 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 and SCE believe the outcome of each of these other proceedings will not individually or in the aggregate, materially affect its financial position, results of operations and cash flows.

San Onofre Related Matters
Replacement steam generators were installed at San Onofre

Southern California Wildfires and Mudslides

California has experienced unprecedented weather conditions in 2010recent years due to climate change and 2011. On January 31, 2012, a leak suddenly occurredwildfires in one of the heat transfer tubes in San Onofre's Unit 3 steam generators. The Unit was safely taken off-line and subsequent inspections revealed excessive tube wear. Unit 2 was off-line for a planned outage when areas of unexpected tube wear were also discovered. On June 6, 2013, SCE decidedSCE's territory, including those where SCE's equipment may be alleged to permanently retire Units 2 and 3.

San Onofre CPUC Proceedings
In November 2014, the CPUC unanimously approved the Settlement Agreement by and among SCE, The Utility Reform Network, the CPUC's Office of Ratepayer Advocates and San Diego Gas & Electric ("SDG&E"), which was later joined by the Coalition of California Utility Employees and Friends of the Earth, dated November 20, 2014 (the "San Onofre OII Settlement Agreement"), which resolved the CPUC's investigation regarding the steam generator replacement project at San Onofre and the related outages and subsequent shutdown of San Onofre. Subsequently, the San Onofre Order Instituting Investigation ("OII") proceeding record was reopened by a joint ruling of the Assigned Commissioner and the Assigned administrative law judge ("ALJ") to consider whether, in light of SCE not reporting certain ex parte communications on a timely basis, the San Onofre OII Settlement Agreement remained reasonable, consistentbe associated with the law,fire's ignition, have caused loss of life and substantial damage in the public interest, which is the standard the CPUC applies in reviewing settlements submitted for approval. In comments filed with the CPUC in July 2016, SCE asserted that the San Onofre OII Settlement Agreement continuesrecent years. SCE's service territory remains susceptible to meet this standard and therefore should not be disturbed. additional wildfire activity.

Numerous claims related to which the failure to timely report ex parte communications had impacted the settlement negotiations and directedwildfire events have been initiated against SCE and SDG&E to meetEdison International. Edison International and confer with the other partiesSCE have incurred material losses in the San Onofre OII to consider changing the terms of the San Onofre OII Settlement Agreement. In March 2017, SCE and the parties participating in the meet-and-confer process initiated a mediation of the issues identified in the December 2016 joint ruling. On August 15, 2017, SCE notified the CPUC that the parties in the San Onofre OII Settlement Agreement were unable to reach agreement on possible changes to the settlement unanimously approved by the CPUC in 2014. In connection with the termination2017/2018 Wildfire/Mudslide Events (defined below), which are described below. In addition, SCE's equipment has been, and may further be, alleged to be associated with wildfires that have originated in Southern California subsequent to 2018.

Liability Overview

The extent of legal liability for wildfire-related damages in actions against utilities depends on a number of factors, including whether the utility substantially caused or contributed to the damages and whether parties seeking recovery of damages will be required to show negligence in addition to causation. California courts have previously found utilities to be strictly liable for property damage along with associated interest and attorneys' fees, regardless of fault, by applying the theory of inverse condemnation when a utility's facilities were determined to be a substantial cause of a wildfire that caused the property damage. If inverse condemnation is held to be inapplicable to SCE in connection with a wildfire, SCE still could be held liable for property damages and associated interest if the property damages were found to have been proximately caused by SCE's negligence. If SCE were to be found negligent, SCE could also be held liable for, among other things, fire suppression costs, business interruption losses, evacuation costs, clean-up costs, medical expenses, and personal injury/wrongful death claims. Additionally, SCE could potentially be subject to fines and penalties for alleged violations of CPUC rules and state laws investigated in connection with the ignition of a wildfire.

Final determinations of legal liability for wildfire events, including determinations of whether SCE was negligent, would only be made during lengthy and complex litigation processes and settlements may be reached before determinations of legal liability are ever made. Even when investigations are still pending or legal liability is disputed, an assessment of likely outcomes, including through future settlement of disputed claims, may require estimated losses to be accrued under accounting standards. Each reporting period, management reviews its loss estimates for remaining alleged and potential claims related to wildfire events. The process for estimating losses associated with alleged and potential wildfire related claims requires management to exercise significant judgment based on a number of assumptions and subjective factors, including, but not limited to: estimates of known and expected claims by third parties based on currently available information, opinions of counsel regarding litigation risk, the status of and developments in the course of litigation, and prior experience litigating and settling wildfire litigation claims. As additional information becomes available, management's estimates and assumptions regarding the causes and financial impact of wildfire events may change. Actual losses incurred may be higher or lower than estimated based on several factors, including the uncertainty in estimating damages that have been or may be alleged.

2017/2018 Wildfire/Mudslide Events

Wildfires in SCE's territory in December 2017 and November 2018 caused loss of life, substantial damage to both residential and business properties, and service outages for SCE customers. The investigating government agencies, the Ventura County Fire Department ("VCFD") and California Department of Forestry and Fire Protection ("CAL FIRE"), have determined that the largest of the meet-and-confer process, SCE asked the CPUC to



affirm that the San Onofre OII Settlement Agreement is fair, reasonable and2017 fires in SCE's territory originated on December 4, 2017, in the public interest. A numberAnlauf Canyon area of Ventura County (the investigating agencies refer to this fire as the "Thomas Fire"), followed shortly thereafter by a second fire that originated near Koenigstein Road in the City of Santa Paula (the "Koenigstein Fire"). The December 4, 2017 fires eventually burned substantial acreage in both Ventura and Santa Barbara Counties. According to CAL FIRE, the Thomas and Koenigstein Fires, collectively, burned over 280,000 acres, destroyed or damaged an estimated 1,343 structures and resulted in two confirmed fatalities. The largest of the partiesNovember 2018 fires in SCE's territory, known as the "Woolsey Fire," originated in Ventura County and burned acreage in both Ventura and Los Angeles Counties. According to CAL FIRE, the San Onofre OII, however,Woolsey Fire burned almost 100,000 acres, destroyed an estimated 1,643 structures, damaged an estimated 364 structures and resulted in three confirmed fatalities. Four additional fatalities are alleged to have requested thatbeen associated with the CPUC either modify the San Onofre OII Settlement Agreement or vacate its previous approval of the settlement and reinstate the San Onofre OII for further proceedings. Several of the parties to the meet-and-confer process petitioned the CPUC on a broad range of litigation positions, certain of which included substantial additional disallowances.
On October 10, 2017, the Assigned Commissioner and ALJ issued a Ruling ordering additional process to resolve the San Onofre OII. The Ruling did not set aside nor confirm the San Onofre OII Settlement Agreement but stated that the CPUC required an additional record to address the appropriate cost allocation for the premature shutdown of San Onofre Units 2 and 3, in the event the CPUC decides that the settlement does not meet the CPUC's standards for approval of settlements. The Ruling sets an expedited schedule with a status conference on November 7, 2017 and hearings tentatively scheduled to end in March 2018. The CPUC has not announced the expected timing for a decision.
SCE has recorded a regulatory asset of $730 million at September 30, 2017 to reflect the expected recoveries under the San Onofre OII Settlement Agreement. Management assesses at the end of each reporting period whether regulatory assets are probable of future recovery. SCE assessed the San Onofre regulatory asset at September 30, 2017 and continues to conclude that the asset is probable, though not certain, of recovery based on SCE's knowledge of facts and judgment in applying the relevant regulatory principles to the issue. Such judgment is subject to uncertainty, and regulatory principles and precedents are not necessarily binding and are subject to interpretation.
Additional ChallengesWoolsey Fire.

As described below, multiple lawsuits related to the SettlementThomas and Koenigstein Fires and the Woolsey Fire have been initiated against SCE and Edison International. Some of San Onofre CPUC Proceedingsthe Thomas and Koenigstein Fires lawsuits claim that SCE and Edison

According to permit rate recoverySanta Barbara County initial reports, the Montecito Mudslides destroyed an estimated 135 structures, damaged an estimated 324 structures, and resulted in 21 confirmed fatalities, with two additional fatalities presumed. One of San Onofre coststhe presumed fatalities was subsequently confirmed to be associated with the Montecito Mudslides.

The Thomas Fire, the Koenigstein Fire, the Montecito Mudslides (defined below) and an applicationthe Woolsey Fire are each referred to as a "2017/2018 Wildfire/Mudslide Event," and, collectively, referred to as the "2017/2018 Wildfire/Mudslide Events."

Each reporting period, management reviews its loss estimates for remaining alleged and potential claims related to the CPUC2017/2018 Wildfire/Mudslide Events. As a result of management's first quarter 2023 review, a $90 million increase in estimated losses for rehearingthe 2017/2018 Wildfire/Mudslide Events as of its decision approvingMarch 31, 2023 was recorded. As a result, Edison International and SCE also recorded expected recoveries through FERC electric rates of $6 million against the San Onofre OII Settlement Agreement were filed in November and December 2014, respectively. In April 2015, the federal lawsuit was dismissed with prejudicecharge, and the plaintiffs in that case appealedresulting net charge to earnings was $84 million ($61 million after-tax).

As of March 31, 2023, SCE had paid $7.8 billion under executed settlements, had $135 million to be paid under executed settlements, including $120 million to be paid under the dismissalSED Agreement (as defined below), and had $853 million of estimated losses for remaining alleged and potential claims reflected on its consolidated balance sheets related to the Ninth Circuit in May 2015. In light2017/2018 Wildfire/Mudslide Events. As of the San Onofre OII meet-and-confer sessions,same date, SCE had assets for expected recoveries through FERC electric rates of $63 million on its consolidated balance sheets and had exhausted expected insurance recoveries related to the Ninth Circuit cancelled2017/2018 Wildfire/Mudslide Events.

The estimated losses for the hearing that had been scheduled for February 9, 20172017/2018 Wildfire/Mudslide Events do not include an estimate of potential losses related to certain alleged and orderedpotential claims made by the parties to notify the Ninth CircuitCalifornia Governor's Office of the status of the San Onofre OII by May 1, 2017 and periodically thereafter. In October 2017, the Ninth Circuit scheduled a hearing for February 13, 2018 and directed the parties to file a status report on January 30, 2018.

In July 2015, a purported securities class action lawsuit was filed in federal court against Edison International, its then Chief Executive Officer and its then Chief Financial Officer. The complaint was later amended to include SCE's former President as a defendant. The lawsuit alleges that the defendants violated the securities laws by failing to disclose that Edison International had ex parte contacts with CPUC decision-makers regarding the San Onofre OII that were either unreported or more extensive than initially reported. The initial complaint purported to be filedEmergency Service ("Cal OES") seeking recovery on behalf of a classitself and 30 state and local government entities that did not pursue their own suits against SCE, but sustained damage in the 2017/2018 Wildfire/Mudslide Events and received funding through the Federal Emergency Management Agency ("FEMA") that was dispersed by the Cal OES. As of persons who acquired the filing of this report, SCE has not concluded that losses related to FEMA funds disbursed by Cal OES are probable.

Edison International common stock between March 21, 2014 and June 24, 2015 (the "Class Period"). In September 2016, the federal court granted defendants' motion to dismiss the complaint, with an opportunity for plaintiff to amend the complaint. Plaintiff filed an amended complaint, which the federal court dismissed again with an opportunity for the plaintiff to amend the complaint. Plaintiff filedSCE may incur a third amended complaintmaterial loss in May 2017, which extends the Class Period to August 10, 2015. Defendants filed a motion to dismiss the third amended complaintexcess of amounts accrued in June 2017, and are awaiting a ruling.

Also in July 2015, a federal shareholder derivative lawsuit was filed against members of the Edison International Board of Directors for breach of fiduciary duty and other claims. The federal derivative lawsuit is based on similar allegations to the federal class action securities lawsuit and seeks monetary damages, including punitive damages, and various corporate governance reforms. An additional federal shareholder derivative lawsuit making essentially the same allegations was filed in August 2015 and was subsequently consolidatedconnection with the July 2015 federal derivative lawsuit. In September 2016, the federal court granted defendants' motion to dismiss the consolidated complaint, with an opportunity for plaintiffs to amend the complaint. Plaintiffs did not file an amended complaint by the required date. Plaintiffs' deadline to appeal the federal court's order granting defendants' motion to dismiss lapsed in March 2017remaining alleged and no appeal was filed.
In October 2015, a shareholder derivative lawsuit was filed in California state court against members of the Edison International Board of Directors for breach of fiduciary duty and otherpotential claims making similar allegations to those in the federal derivative lawsuits discussed above. In light of the ruling in the parallel federal derivative lawsuit discussed above, plaintiff requested that the court voluntarily dismiss the state court action. The action was dismissed in April 2017.
In November 2015, a purported securities class action lawsuit was filed in federal court against Edison International, its then Chief Executive Officer and its Treasurer by an Edison International employee, alleging claims under the Employee Retirement Income Security Act. The complaint purports to be filed on behalf of a class of Edison International employees who were participants in the Edison 401(k) Savings Plan and invested in the Edison International Stock Fund between March 27, 2014 and June 24, 2015. The complaint alleges that defendants breached their fiduciary duties because they knew


or should have known that investment in the Edison International Stock Fund was imprudent because the price of Edison International common stock was artificially inflated due to Edison International's alleged failure to disclose certain ex parte communications with CPUC decision-makers related to the San Onofre OII.

Due to the federal court grantednumber of uncertainties and possible outcomes related to the defendants' motion to dismiss the lawsuit with an opportunity for the plaintiff to amend her complaint. Plaintiff filed an amended complaint in July 2016, that dismissed Edison International as a named defendant and the remaining defendants filed a motion to dismiss in August 2016. These defendants' motion was heard by the court in November 2016. In June 2017, the federal court again granted defendants' motion to dismiss the lawsuit with an opportunity for the plaintiff to amend her complaint. Plaintiff filed an amended complaint in early July 2017. Defendants have filed motion to dismiss the amended complaint, which was heard by the court in October 2017, and are awaiting a ruling.
2017/2018 Wildfire/Mudslide Events litigation, Edison International and SCE cannot predictestimate the outcomeupper end of the open proceedings.range of reasonably possible losses that may be incurred.

Estimated losses for the 2017/2018 Wildfire/Mudslide Events litigation are based on a number of assumptions and are subject to change as additional information becomes available. Actual losses incurred may be higher or lower than estimated based on several factors, including the uncertainty in estimating damages that have been or may be alleged. For instance, SCE will receive additional information with respect to damages claimed as the claims mediation processes progress. Other factors that can cause actual losses incurred to be higher or lower than estimated include the ability to reach settlements and the outcomes of settlements reached through the ongoing claims mediation processes, uncertainties related to the sufficiency of insurance held by plaintiffs, uncertainties related to the litigation processes, including whether plaintiffs will ultimately pursue claims, uncertainty as to the legal and factual determinations to be made during litigation, including uncertainty as to the contributing causes of the 2017/2018 Wildfire/Mudslide Events, the complexities associated with fires that merge and whether inverse condemnation will be held applicable to SCE with respect to damages caused by the Montecito Mudslides, and the uncertainty as to how these factors impact future settlements.

The CPUC and FERC may not allow SCE to recover uninsured losses through electric rates if it is determined that such losses were not prudently incurred. SCE will seek rate recovery of prudently incurred losses and related costs realized in connection with the 2017/2018 Wildfire/Mudslide Events in excess of available insurance, other than for any obligations

and Potential Recoveries from Insurance and through Electric Rates" below for additional information.

External Investigations and Internal Review

The VCFD and CAL FIRE have jointly issued reports concerning their findings regarding the causes of the Thomas Fire and the Koenigstein Fire. The reports did not address the causes of the Montecito Mudslides. SCE pursued claims against MHI, whichhas also received a non-final redacted draft of a report from the VCFD regarding Woolsey Fire (the "Redacted Woolsey Report"). SCE cannot predict when the VCFD will release its final report regarding the Woolsey Fire. The VCFD and CAL FIRE findings do not determine legal causation of or assign legal liability for the Thomas, Koenigstein or Woolsey Fires; final determinations of legal causation and liability would only be made during lengthy and complex litigation.

The CPUC's Safety and Enforcement Division ("SED") conducted investigations to assess SCE's compliance with applicable rules and regulations in areas impacted by the Thomas, Koenigstein and Woolsey Fires. As discussed below, in October 2021, SCE and the SED executed the SED Agreement (as defined below) to resolve the SED's investigations into the 2017/2018 Wildfire/Mudslide Events.

The California Attorney General's Office has completed its investigation of the Thomas Fire and the Woolsey Fire without pursuing criminal charges.

SCE's internal review into the facts and circumstances of each of the 2017/2018 Wildfire/Mudslide Events is complex and time consuming. SCE expects to obtain and review additional information and materials in the possession of third parties during the course of its internal reviews and the litigation processes.

Thomas Fire

On March 13, 2019, the VCFD and CAL FIRE jointly issued a report concluding, after ruling out other possible causes, that the Thomas Fire was started by SCE power lines coming into contact during high winds, resulting in molten metal falling to the ground. However, the report does not state that their investigation found molten metal on the ground. At this time, based on available information, SCE has not determined whether its equipment caused the Thomas Fire. Based on publicly available radar data showing a smoke plume in the Anlauf Canyon area emerging in advance of the report's indicated start time, SCE believes that the Thomas Fire started at least 12 minutes prior to any issue involving SCE's system and at least 15 minutes prior to the start time indicated in the report. SCE is continuing to assess the extent of damages that may be attributable to the Thomas Fire.

Koenigstein Fire

On March 20, 2019, the VCFD and CAL FIRE jointly issued a report finding that the Koenigstein Fire was caused when an energized SCE electrical wire separated and fell to the ground along with molten metal particles and ignited the dry vegetation below. SCE believes that its equipment was associated with the ignition of the Koenigstein Fire. SCE is continuing to assess the extent of damages that may be attributable to the Koenigstein Fire.

Montecito Mudslides

SCE's internal review includes inquiry into whether the Thomas and/or Koenigstein Fires proximately caused or contributed to the Montecito Mudslides, whether, and to what extent, the Thomas and/or Koenigstein Fires were responsible for the damages in the Montecito area and other factors that potentially contributed to the losses that resulted from the Montecito Mudslides. Many other factors, including, but not limited to, weather conditions and insufficiently or improperly designed and suppliedmaintained debris basins, roads, bridges and other channel crossings, could have proximately caused, contributed to or exacerbated the replacement steam generators. losses that resulted from the Montecito Mudslides.

At this time, based on available information, SCE has not been able to determine whether the Thomas Fire or the Koenigstein Fire, or both, were responsible for the damages in the Montecito area. In the event that SCE is determined to have caused the fire that spread to the Montecito area, SCE cannot predict whether, if fully litigated, the courts would conclude that the Montecito Mudslides were caused or contributed to by the Thomas and/or Koenigstein Fires or that SCE would be liable for some or all of the damages caused by the Montecito Mudslides.

Woolsey Fire

SCE's internal review into the facts and circumstances of the Woolsey Fire is ongoing. SCE has reported to the CPUC that there was an outage on SCE's electric system in the vicinity of where the Woolsey Fire reportedly began on November 8, 2018. SCE is aware of witnesses who saw fire in the vicinity of SCE's equipment at the time the fire was first reported. While SCE did not find evidence of downed electrical wires on the ground in the suspected area of origin, it observed a pole support wire in proximity to an electrical wire that was energized prior to the outage.

The Redacted Woolsey Report states that the VCFD investigation team determined that electrical equipment owned and operated by SCE was the cause of the Woolsey Fire. Absent additional evidence, SCE believes that it is likely that its equipment was associated with the ignition of the Woolsey Fire. SCE expects to obtain and review additional information and materials in the possession of CAL FIRE and others during the course of its internal review and the Woolsey Fire litigation process, including SCE equipment that has been retained by CAL FIRE.

Litigation

Multiple lawsuits related to the 2017/2018 Wildfire/Mudslide Events naming SCE as a defendant have been filed by three categories of plaintiffs: individual plaintiffs, subrogation plaintiffs and public entity plaintiffs. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. The litigation could take a number of years to be resolved because of the complexity of the matters and number of plaintiffs.

On October 4, 2018, the Los Angeles Superior Court denied Edison International's and SCE's challenge to the application of inverse condemnation to SCE with respect to the Thomas and Koenigstein Fires and, on February 26, 2019, the California Supreme Court denied SCE's petition to review the Superior Court's decision. In April 2022, following a stipulated judgment entered against SCE in the TKM litigation, SCE filed an appeal related to inverse condemnation in the California Court of Appeal.

In January 2019, SCE filed a cross-complaint against certain local public entities alleging that failures by these entities, such as failure to adequately plan for flood hazards and build and maintain adequate debris basins, roads, bridges and other channel crossings, among other things, caused, contributed to or exacerbated the losses that resulted from the Montecito Mudslides. These cross-claims in the Montecito Mudslides litigation were not released as part of the Local Public Entity Settlements (as defined below).

Settlements

In the fourth quarter of 2019, SCE paid $360 million to a number of local public entities to resolve those parties' collective claims arising from the 2017/2018 Wildfire/Mudslide Events (the "Local Public Entity Settlements").

In the third quarter of 2020, Edison International and SCE entered into an agreement (the "TKM Subrogation Settlement") under which all of the insurance subrogation plaintiffs' in the Thomas Fire, Koenigstein Fire and Montecito Mudslides litigation (the "TKM Subrogation Plaintiffs") collective claims arising from the Thomas Fire, Koenigstein Fire or Montecito Mudslides have been resolved. Under the TKM Subrogation Settlement, SCE paid the TKM Subrogation Plaintiffs an aggregate of $1.2 billion in October 2020 and also agreed to pay $0.555 for each dollar in claims to be paid by the TKM Subrogation Plaintiffs to their policy holders on or before July 15, 2023, up to an agreed upon cap.

In January 2021, Edison International and SCE entered into an agreement (the "Woolsey Subrogation Settlement") under which all of the insurance subrogation plaintiffs' in the Woolsey Fire litigation (the "Woolsey Subrogation Plaintiffs") collective claims arising from the Woolsey Fire have been resolved. Under the Woolsey Subrogation Settlement, SCE paid the Woolsey Subrogation Plaintiffs an aggregate of $2.2 billion in March and April 2021. SCE has also agreed to pay $0.67 for each dollar in claims to be paid by the Woolsey Subrogation Plaintiffs to their policy holders on or before July 15, 2023, up to an agreed upon cap.

As of March 31, 2023, SCE has also entered into settlements with approximately 10,000 individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation. In 2022, 2021 and 2020, SCE entered into settlements with individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation under which it agreed to pay an aggregate of approximately $1.7 billion, $1.7 billion and $300 million, respectively, to those individual plaintiffs. In the first quarter of 2023, SCE entered into settlements with individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events litigation under which it agreed to pay an aggregate of approximately $148 million to those individual plaintiffs. The statutes of limitations for individual plaintiffs in the 2017/2018 Wildfire/Mudslide Events have expired.

Edison International and SCE did not admit wrongdoing or liability as part of any of the settlements described above. Other claims and potential claims related to the 2017/2018 Wildfire/Mudslide Events remain. SCE continues to explore reasonable settlement opportunities with other plaintiffs in the outstanding 2017/2018 Wildfire/Mudslide Events litigation.

SED Agreement

In October 2013,2021, SCE sent MHIand the SED executed an agreement (the "SED Agreement") to resolve the SED's investigations into the 2017/2018 Wildfire/Mudslide Events and three other 2017 wildfires for, among other things, aggregate costs of $550 million. The $550 million in costs comprised of a formal request$110 million fine to be paid to the State of California General Fund, $65 million of shareholder-funded safety measures, and an agreement by SCE to waive its right to seek cost recovery in CPUC-jurisdictional rates for binding arbitration$375 million of third-party uninsured claims payments. The SED Agreement provides that SCE may, on a permanent basis, exclude from its ratemaking capital structure any after-tax charges to equity or debt borrowed to finance costs incurred under the auspicesSED Agreement. The SED Agreement also imposes other obligations on SCE, including reporting requirements and safety-focused studies. SCE's obligations under the SED Agreement commenced on August 15, 2022, when CPUC approval of the International ChamberSED Agreement became final and non-appealable. SCE did not admit imprudence, negligence or liability with respect to the 2017/2018 Wildfire/Mudslide Events in the SED Agreement.

Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates

At March 31, 2023 and December 31, 2022, Edison International's and SCE's consolidated balance sheets included fixed payments to be made under executed settlement agreements and accrued estimated losses of Commerce seeking damages$1.0 billion and $1.1 billion, respectively, for the 2017/2018 Wildfire/Mudslide Events.

At December 31, 2022, the $1,687 million included in deferred credits and other liabilities, wildfire-related claims, on Edison International's and SCE's consolidated balance sheets included Edison International's and SCE's best estimate of expected losses for remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events of $934 million, $64 million of a long term payables under the SED Agreement and other wildfire-related claims estimates of $689 million.
2At March 31, 2023, $75 million in current liabilities, wildfire-related claims, on Edison International's and SCE's consolidated balance sheets consisted of $15 million of settlements executed and $60 million of a short term payables under the SED Agreement in connection with the 2017/2018 Wildfire/Mudslide Events. At March 31, 2023, the $1,600 million included in deferred credits and other liabilities, wildfire-related claims, on Edison International's and SCE's consolidated balance sheets included Edison International's and SCE's best estimate of expected losses for remaining alleged and potential claims related to the 2017/2018 Wildfire/Mudslide Events of $853 million, $60 million of a long term payables under the SED Agreement and other wildfire-related claims estimates of $687 million.

For the three months ended March 31, 2023 and 2022, Edison International's and SCE's consolidated statements of income included charges for the estimated losses, net of expected recoveries from insurance and FERC customers, related to the 2017/2018 Wildfire/Mudslide Events as follows:

For events that occurred in 2017 and early 2018, principally the Thomas and Koenigstein Fires and Montecito Mudslides, SCE had $1.0 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence. For the Woolsey Fire, SCE had an additional $1.0 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence.

In total, through March 31, 2023, SCE has accrued estimated losses of $8.8 billion, has paid or is obligated to pay approximately $7.9 billion in settlements, including $120 million to be paid under the SED Agreement, and has recovered $2.0 billion from its insurance carriers in relation to the 2017/2018 Wildfire/Mudslide Events.

Recovery of SCE's losses realized in connection with the 2017/2018 Wildfire/Mudslide Events in excess of available insurance is subject to approval by regulators. Under accounting standards for rate-regulated enterprises, SCE defers costs as regulatory assets when it concludes that such costs are probable of future recovery in electric rates. SCE utilizes objectively determinable evidence to form its view on probability of future recovery. The only directly comparable precedent in which a California investor-owned utility has sought recovery for uninsured wildfire-related costs is San Diego Gas & Electric's ("SDG&E") requests for cost recovery related to 2007 wildfire activity, where the FERC allowed recovery of all FERC-jurisdictional wildfire-related costs while the CPUC rejected recovery of all CPUC-jurisdictional wildfire-related costs based on a determination that SDG&E did not meet the CPUC's prudency standard. As a result, while SCE does not agree with the

52

Table of Contents

CPUC's decision, it believes that the CPUC's interpretation and application of the prudency standard to SDG&E creates substantial uncertainty regarding how that standard will be applied to an investor-owned utility in wildfire cost-recovery proceedings for fires ignited prior to July 12, 2019. SCE will continue to evaluate the probability of recovery based on available evidence, including judicial, legislative and regulatory decisions, including any CPUC decisions illustrating the interpretation and/or application of the prudency standard when making determinations regarding recovery of uninsured wildfire-related costs. While the CPUC has not made a determination regarding SCE's prudency relative to any of the 2017/2018 Wildfire/Mudslide Events, SCE is unable to conclude, at this time, that uninsured CPUC-jurisdictional wildfire-related costs are probable of recovery through electric rates. SCE would record a regulatory asset at the time it obtains sufficient information to support a conclusion that recovery is probable.

Through the operation of its FERC Formula Rate, and based upon the precedent established in SDG&E's recovery of FERC-jurisdictional wildfire-related costs, SCE believes it is probable it will recover its FERC-jurisdictional wildfire and mudslide related costs and has recorded total expected recoveries of $382 million within the FERC balancing account. This was the FERC portion of the total estimated losses accrued. As of March 31, 2023, collections have reduced the regulatory assets remaining in the FERC balancing account to $63 million.

In July 2019, SCE filed a CEMA application with the CPUC to seek recovery of, among other things, approximately $60 million of capital expenditures and capital related expenses incurred to restore service to customers and to repair, replace and restore buildings and SCE's facilities damaged or destroyed as a result of six 2017 fires, primarily the Thomas and Koenigstein Fires. In August 2021, the CPUC issued a final decision which denied without prejudice SCE's application to recover a revenue requirement of $8 million for all losses.six 2017 wildfires on the basis that SCE did not demonstrate that it was prudent in relation to the Thomas and Rye fires and had failed to segregate the costs attributable to the other four fires. Of the $8 million revenue requirement that was denied, $6 million was for the Thomas and Rye fires. CAL FIRE has determined that the Thomas and Rye fires were caused by SCE equipment. The decision allows SCE to submit additional applications with the CPUC to recover the costs associated with the Thomas and Rye fires, does not specify a deadline for any such applications, and directs that SCE must prove it was prudent in relation to the Thomas and/or Rye fires, as applicable, in any such future applications. As required by the final decision with respect to the other four fires, SCE filed supplemental testimony in November 2021 segregating the restoration costs attributable to each such fire. In June 2022, the CPUC approved SCE's entire request with respect to the other four fires. As of March 31, 2023, SCE has $176 million in assets recorded in property, plant and equipment in relation to restoration costs related to the 2017/2018 Wildfire/Mudslide Events which may not be recoverable. These assets would be impaired if the restoration costs are permanently disallowed by the CPUC in future cost recovery proceedings. SCE expects to seek to recover costs incurred for reconstructing its system and restoring service to structures that were damaged or destroyed by the Thomas, Koenigstein and Woolsey Fires in future applications with the CPUC.

Post-2018 Wildfires

Several wildfires have significantly impacted portions of SCE's service territory after 2018 (the wildfires that originated in Southern California after 2018 where SCE's equipment may be alleged contractto be associated with the fire's ignition are referred to collectively as the "Post-2018 Wildfires"). Numerous claims related to the Post-2018 Wildfires have been initiated against SCE and tortEdison International. The SED is also conducting investigations with respect to several Post-2018 Wildfires.

Through March 31, 2023, SCE has recorded total estimated losses of $702 million, expected recoveries from insurance of $473 million and expected recoveries through electric rates of $166 million related to the Post-2018 Wildfires. The after-tax net charges to earnings recorded through March 31, 2023 have been $45 million.

As of March 31, 2023, SCE had paid $21 million under executed settlements related to the Post-2018 Wildfires and Edison International's and SCE's estimated losses for remaining alleged and potential claims related to the Post-2018 Wildfires was $681 million. As of the same date, SCE had assets for expected recoveries through insurance of $473 million and soughtthrough electric rates of $166 million on its consolidated balance sheets related to the Post-2018 Wildfires.

Table of Contents

Expected recoveries from insurance recorded for the Post-2018 Wildfires are supported by SCE's insurance coverage for multiple policy years. While Edison International and SCE may incur material losses in excess of the amounts accrued for certain of the Post-2018 Wildfires, Edison International and SCE expect that any losses incurred in connection with any such fire will be covered by insurance, subject to self-insured retentions and co-insurance, and expect that any such losses after expected recoveries from insurance and through electric rates will not be material.

2019 Saddle Ridge Fire

The "Saddle Ridge Fire," originated in Los Angeles County in October 2019 and burned approximately 9,000 acres, destroyed an estimated 19 structures, damaged an estimated 88 structures, and resulted in one fatality and injuries to 8 fire fighters. In an unsigned and undated report that SCE received in December 2022, the Los Angeles Fire Department stated with respect to the Saddle Ridge Fire that the cause of ignition was unintentional, the form of heat was undetermined, the item first ignited was undetermined and the material type first ignited was undetermined. The Los Angeles Fire Department report noted that no other competent ignition sources other than SCE’s transmission lines were found in the specific origin area of the Saddle Ridge Fire. SCE has been advised that the Los Angeles Fire Department investigation of the Saddle Ridge Fire remains open. A jury trial in the Saddle Ridge Fire litigation is currently set for January 2024. Based on pending litigation and without considering insurance recoveries, it is reasonably possible that SCE will incur a material loss in connection with the Saddle Ridge Fire, but the range of reasonably possible losses that could be incurred cannot be estimated at least $4 billionthis time. SCE has not accrued a charge for potential losses relating to the Saddle Ridge Fire.

2020 Bobcat Fire

The "Bobcat Fire" was reported in damagesthe vicinity of Cogswell Dam in Los Angeles County in September 2020. The United States Forest Service ("USFS") has reported that the Bobcat Fire burned approximately 116,000 acres in Los Angeles County, destroyed an estimated 87 homes, 1 commercial property and 83 minor structures, damaged an estimated 28 homes and 19 minor structures, and resulted in injuries to 6 firefighters. In addition, fire authorities have estimated suppression costs at $80 million. While SCE’s investigation remains ongoing, SCE’s information reflects that a camera in the vicinity of Cogswell Dam captured the initial stages of a fire with the first observed smoke approximately six minutes before a SCE circuit in the area experienced an anomaly (a relay). An investigation into the cause of the Bobcat Fire is being led by the USFS, and the USFS has taken a specific section of an SCE overhead conductor in the vicinity of Cogswell Dam into possession as part of its investigation. SCE understands that the USFS has also taken three tree branches in the area into possession. SCE expects to obtain and review additional information and materials in the possession of third parties during the course of its internal reviews and the litigation process. SCE has accrued material charges for potential losses relating to the Bobcat Fire. The accrued charges correspond to the lower end of the estimated range of reasonably possible losses that may be incurred in connection with the Bobcat Fire and are subject to change as additional information becomes available. While Edison International and SCE may incur a material loss in excess of the amount accrued, they cannot estimate the upper end of the range of reasonably possible losses that may be incurred.

2022 Coastal Fire

The "Coastal Fire" originated in Orange County in May 2022 and burned approximately 200 acres. The Orange County Fire Authority ("OCFA") has reported that the Coastal Fire destroyed 20 residential structures and damaged 11 residential structures. Two firefighters also reportedly sustained minor injuries. In addition, fire authorities have estimated suppression costs at approximately $3 million. While SCE's investigation remains ongoing, SCE's information reflects that a SCE circuit in the area experienced an anomaly (a relay) approximately 2 minutes prior to the reported time of the fire. An investigation into the cause of the Coastal Fire is being led by the OCFA. The OCFA has retained SCE equipment in connection with its investigation. SCE expects to obtain and review additional information and materials in the possession of third parties during the course of its internal reviews and the litigation process. SCE has accrued material charges for potential losses relating to the Coastal Fire. The accrued charges correspond to the lower end of the estimated range of reasonably possible losses that may be incurred in connection with the Coastal Fire and are subject to change as additional information becomes available.

While Edison International and SCE may incur a material loss in excess of the amount accrued, they cannot estimate the upper end of the range of reasonably possible losses that may be incurred.

2022 Fairview Fire

The "Fairview Fire" originated in Riverside County in September 2022 and burned approximately 28,000 acres. CAL FIRE has reported that the Fairview Fire destroyed 22 residential structures, damaged 5 residential structures, and destroyed or damaged 17 minor structures. CAL FIRE also reported 2 civilian fatalities, 1 civilian injury and 2 injuries to responding fire personnel. In addition, fire authorities have estimated suppression costs at $39 million. While SCE's investigation remains ongoing, SCE's information reflects that a SCE circuit in the area experienced an anomaly (relay) approximately 8 minutes prior to the reported start time of the fire. An investigation into the cause of the Fairview Fire is being led by CAL FIRE. CAL FIRE has retained SCE equipment in connection with its investigation. SCE expects to obtain and review additional information and materials in the possession of third parties during the course of its internal reviews and the litigation process. SCE has accrued material charges for potential losses relating to the Fairview Fire. The accrued charges correspond to the lower end of the estimated range of reasonably possible losses that may be incurred in connection with the Fairview Fire and are subject to change as additional information becomes available. While Edison International and SCE may incur a material loss in excess of the amount accrued, they cannot estimate the upper end of the range of reasonably possible losses that may be incurred.

Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates

At March 31, 2023 and December 31, 2022, Edison International's and SCE's consolidated balance sheets included accrued estimated losses of $681 million and $682 million, respectively, for the Post-2018 Wildfires.

Recovery of SCE's losses realized in connection with the Post-2018 Wildfires in excess of available insurance is subject to approval by regulators. The CPUC and FERC may not allow SCE to recover uninsured losses through electric rates if it is determined that such losses were not prudently incurred. Under accounting standards for rate-regulated enterprises, SCE defers costs as regulatory assets when it concludes that such costs are probable of future recovery in electric rates. SCE utilizes objectively determinable evidence to form its view on behalfthe probability of itselffuture recovery. As discussed above, there is evidence of a California investor-owned utility seeking recovery for uninsured wildfire-related costs and FERC allowing recovery of all FERC-jurisdictional wildfire-related costs while the CPUC rejected recovery of all CPUC-jurisdictional

wildfire-related costs based on a determination that the utility did not meet the CPUC's prudency standard. This evidence was prior to the adoption of AB 1054 on July 12, 2019, after which date AB 1054 clarified that the CPUC must find a utility to be prudent if the utility's conduct related to the ignition was consistent with actions that a reasonable utility would have undertaken in good faith under similar circumstances, at the relevant point in time, and based on the information available at that time. Further, utilities with a valid safety certification at the time of the relevant wildfire will be presumed to have acted prudently related to a wildfire ignition unless a party in the cost recovery proceeding creates serious doubt as to the reasonableness of the utility's conduct, at which time, the burden shifts back to the utility to prove its customers and in its capacity as Operating Agent for San Onofre. MHI denied any liability and asserted counterclaims for $41 million, for which SCE denied any liability.conduct was prudent. Each of the Post-2018 Wildfires was ignited after July 12, 2019, and SCE has held a valid safety certificate since July 15, 2019. While a California investor-owned utility has not yet sought recovery for uninsured claims and other San Onofre owners (SDG&Ecosts related to wildfires ignited after the adoption of AB 1054, SCE believes that for fires ignited after July 12, 2019, and Riverside) sued MHI, alleging claims arising from MHI's supplyinginvestor-owned utilities holding a safety certificate at the faulty steam generators. These litigation claims have been stayed pendingtime of the arbitration. Thefire, the CPUC will apply a standard of review similar to that applied by the FERC which presumes all costs requested by an investor-owned utility are reasonable and prudent unless serious doubt as to the reasonableness of the utility’s conduct is raised. As such, SCE has concluded, at this time, that both uninsured CPUC-jurisdictional and uninsured FERC-jurisdictional wildfire-related costs related to the Post-2018 Wildfires, other co-owners were addedthan for those already authorized for inclusion in electric rates, are probable of recovery through electric rates. As of March 31, 2023, SCE has recorded total expected recoveries related to the Post-2018 Wildfires of $152 million within the WEMA and risk management balancing account and $14 million within the FERC balancing account. SCE will continue to evaluate the probability of recovery based on available evidence, including regulatory decisions, including any CPUC decisions illustrating the interpretation and/or application of the prudency standard under AB 1054, and, for each applicable fire, evidence that could cast serious doubt as to the reasonableness of SCE's conduct relative to that fire.

Wildfire Insurance Coverage

SCE has approximately $1.0 billion of wildfire-specific insurance coverage for events that may occur during the period July 1, 2022 through June 30, 2023, subject to up to $100 million of self-insured retention and co-insurance per fire, which results in aggregate net coverage of approximately $937 million. Of this coverage, approximately $102 million is provided by EIS and approximately $835 million is provided by other commercial insurance carriers (commercial insurance carriers other than EIS are referred to herein as "Third-Party Commercial Insurers"). SCE has approximately $1.0 billion of wildfire-specific insurance coverage for events that occurred during the period July 1, 2021 through June 30, 2022, subject to up to $100 million of self-insured retention and co-insurance per fire, as well as additional claimantsco-insurance of up to $63 million for the policy year, which resulted in net coverage of approximately $875 million provided by Third-Party Commercial Insurers and $28 million provided by EIS for part of the arbitration. In March 2017,policy year.

SCE believes that its insurance coverage for the arbitration tribunal found MHI liableJuly 1, 2022 through June 30, 2023 period meets its obligation to maintain reasonable insurance coverage under AB 1054. Edison International and SCE record a receivable for breachinsurance recoveries when recovery of contract, but rejected claimants' other claims. The tribunal found that damages were subject to contractual limitations on liability. In addition, the tribunal ordered the claimants to pay MHI's legal costs but rejected MHI's counterclaims. The net recovery awarded to SCE was initiallya recorded loss is determined to be $52 million. An adjustmentprobable.

SCE's wildfire insurance expense for the July 1, 2022 through June 30, 2023 policy period will be approximately
$450 million, of which $357 million is paid to Third-Party Commercial Insurers. SCE's wildfire insurance expense for the July 1, 2021 through June 30, 2022 policy period was approximately $437 million, of which $413 million was paid to Third-Party Commercial Insurers. The difference between the Third-Party Commercial Insurer cost and total cost in both policy years was paid in premiums to EIS. Wildfire insurance premiums paid for the July 1, 2021 through June 30, 2022 and July 1, 2022 through June 30, 2023 policy periods are being recovered through customer rates. See Note 17 for further information.

While SCE's cost of obtaining wildfire insurance coverage from Third-Party Commercial Insurers was lower in 2022 compared to 2021, SCE's cost of obtaining wildfire insurance coverage in recent years is significantly higher than costs incurred prior to the interest awarded2017/2018 Wildfire/Mudslide Events due to, among other things, the number of significant wildfire events throughout California and the application of inverse condemnation to investor-owned utilities. While SCE subsequently reduced the net recoveryis required to $47 million.

Environmental Remediation

SCE records its environmental remediation and restoration liabilities when site assessments and/or remedial actions are probable and a range of reasonably likely cleanup costs can be estimated. SCE 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, SCE 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, 2017,March 31, 2023, SCE's recorded estimated minimum liability to remediate its 1926 identified material sites (sites with a liability balance at September 30, 2017,March 31, 2023, in which the upper end of the range of theexpected costs is at least $1 million) was $125$254 million, including $74$164 million related to San Onofre. In addition to these sites, SCE also has 1712 immaterial sites with a liability balance as of September 30, 2017,March 31, 2023, for which the total minimum recorded liability was $4$3 million. Of the $129$257 million total environmental remediation liability for SCE, $123$238 million has been recorded as a regulatory asset. SCE expects to recover $46$36 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)sites in this mechanism) and $77$202 million through a mechanismproceedings that allowsallow SCE to recover up to 100% of the costs incurred at certain sites through customer rates. SCE'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 SCE 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 SCE'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. SCE 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 $151$118 million and $8 million, respectively. The upper limit of this range of costs was estimated using assumptions least favorable to SCE among a range of reasonably possible outcomes.



SCE expects to clean up and mitigate its identified sites over a period of up to 3040 years. Remediation costs for each of the next five years are expected to range from $5$8 million to $17$29 million. Costs incurred for the ninethree months ended September 30, 2017March 31, 2023 and 20162022 were $6 million and $3 million, respectively.

both $2 million.

Based upon the CPUC's regulatory treatment of environmental remediation costs incurred at SCE, SCE 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

SCE is a member of NEIL,Nuclear Electric Insurance Limited ("NEIL"), a mutual insurance company owned by entities with nuclear facilities. NEIL provides insurance for nuclear property damage, including damages caused by acts of terrorism up to specified limits, and for accidental outages for active facilities. The amount of nuclear property damage insurance purchased for San Onofre and Palo Verde exceeds the minimum federal requirement of $1.06 billion.$50 million and $1.1 billion, respectively. If

57

Table of Contents

NEIL 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 $52$30 million per year.

Federal law limits public offsite liability claims for bodily injury and property damage from a nuclear incident to the amount of available financial protection, which is currently approximately $13.4 billion.$560 million for San Onofre and $13.7 billion for Palo Verde. SCE and other owners of San Onofre and Palo Verde have purchased the maximum private primary insurance available through a Facility Form issued by American Nuclear Insurers. SCE withdrew from participation in the secondary insurance pool for San Onofre for offsite liability insurance effective January 5, 2018. Based on its ownership interests in Palo Verde, SCE could be required to pay a maximum of approximately $65 million per nuclear incident for future incidents. However, it would have to pay no more than approximately $10 million per future incident in any one year. Based on its ownership interests in San Onofre and Palo Verde prior to January 5, 2018, SCE could be required to pay a maximum of approximately $255 million per nuclear incident. However, it would have to pay no more than approximatelyincident and a maximum of $38 million per year per incident for liabilities arising from events prior to January 5, 2018, although SCE is not aware of any such events.

Note 13. Equity

Common Stock Issuances

As of March 31, 2023, Edison International has not issued any shares through its "at-the-market" ("ATM") program established in any one year.

For more information on nuclear insurance coverage, see Note 11August 2022. Under the ATM program, Edison International may sell shares of its common stock having an aggregate sales price of up to $500 million. Edison International has no obligation to sell the remaining shares available under the ATM program.

Edison International continued to settle its ongoing common stock requirements of various internal programs through issuance of new common stock. During the three months ended March 31, 2023, 324,438 shares of common stock were issued as stock compensation awards for net cash receipts of $11 million, 67,314 shares of new common stock were issued in lieu of distributing $5 million to shareholders opting to receive dividend payments in the 2016 Form 10-K.

Wildfire Insurance
Severe wildfires in California have given riseform of additional common stock, 29,000 shares of common stock were issued to large damage claims against California utilitiesemployees through the 401(k) defined contribution savings plan for fire-related losses allegednet cash receipts of $2 million as dividend payments and 26,481 shares of common stock were issued to beemployees through the resultESPP for net cash receipts of utility practices and/orthe 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. Drought and other severe weather conditions in California have also increased the duration of the wildfire season and the risk of severe wildfire events. SCE has approximately $1 billion of insurance coverage for wildfire liabilities for the period ending on May 31, 2018. SCE has a self-insured retention of $10 million per wildfire occurrence. Various coverage limitations within the policies that make up this insurance coverage could result in additional self-insured costs in the event of multiple wildfire occurrences during the policy period. SCE or its vegetation management contractors 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 insurance coverage. In the event of fire-related losses involving utility practices and/or the failure of electric and other utility equipment, SCE may be unable to recover self-insured retention or losses in excess of insurance coverage from customers.
Spent Nuclear Fuel
Under federal law, the U.S. 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 has not met its contractual obligation to accept spent nuclear fuel. 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 their 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 (SCE share $112 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 April 2016, SCE, as operating agent, settled a lawsuit on behalf of the San Onofre owners against the DOE for $162 million, including reimbursement for legal costs (SCE share $124 million) to compensate for damages caused by the DOE's failure to meet its obligation to begin accepting spent nuclear fuel for the period from January 1, 2006 to December 31, 2013. The settlement also provides for a claim submission/audit process for expenses incurred from 2014 – 2016, where SCE will submit a claim for damages caused by the DOE failure to accept spent nuclear fuel each year, followed by a government audit and payment of the claim. This process will make additional legal action to recover damages incurred in 2014 – 2016 unnecessary. The first such claim covering damages for 2014 – 2015 was filed on September 30, 2016 for approximately $56$2 million. In February 2017, the DOE reviewed the 2014 – 2015 claim submission and reduced the original request to approximately $43 million (SCE share was approximately $34 million) primarily due to DOE allocation limits. SCE accepted the DOE's determination, and the government paid the


2014 – 2015 claim under the terms of the settlement. In October 2017, SCE filed a claim covering damages for 2016 for approximately $59 million. All 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.
In August 2017, SCE settled a dispute brought by Citizens Oversight and an individual that sought to overturn the California Coastal Commission's approval of a coastal development permit granted in October 2015 for the expansion of San Onofre ISFSI (a dry cask storage facility for the long-term, on-site storage of nuclear fuel). The plaintiffs primarily alleged that the California Coastal Commission did not adequately consider alternative, offsite locations for the ISFSI. The parties' settlement permits the current ISFSI project to proceed while steps are taken to identify the potential for moving the fuel offsite in the future. In the settlement, SCE agreed to use "commercially reasonable efforts" to relocate San Onofre fuel to an offsite storage facility, agreeing to spend up to $4 million, which will be funded by the nuclear decommissioning trust, principally for retaining experts and preparing spent nuclear fuel transportation and strategic plans applicable to a potential relocation of the fuel.
SCE Collective Bargaining Agreement
Approximately 3,900 of SCE's full-time employees are covered by collective bargaining agreements with the International Brotherhood of Electrical Workers ("IBEW"). SCE and IBEW recently negotiated, and among other things, IBEW ratified, 3% per year wage increases covering calendar years 2018 and 2019. The wage increases are effective as of October 2, 2017. The IBEW collective bargaining agreements expire on December 31, 2019.

Note 12.    Preferred and Preference Stock of SCE
During the second quarter of 2017, SCE issued $475 million of 5.00% Series L preference stock (190,004 shares; cumulative, $2,500 liquidation value) to SCE Trust VI, a special purpose entity formed to issue trust securities as discussed in Note 3. The Series L preference stock may be redeemed at a premium, in whole, but not in part, at any time prior to June 26, 2022 if certain changes in tax or investment company law or interpretation or applicable rating agency equity credit criteria occur and certain other conditions are satisfied. On or after June 26, 2022, SCE may redeem the Series L shares at par, in whole or in part. The shares are not subject to mandatory redemption. In July 2017, the proceeds were used to redeem $475 million of SCE's Series F Preference Stock.

Note 17. Related-Party Transactions

SCE has previously purchased wildfire liability insurance from EIS, a wholly-owned subsidiary of Edison International. In July 2022, SCE purchased wildfire liability insurance for premiums of $273 million, from EIS for the period to June 30, 2023. EIS fully reinsured the exposure for these policies through the commercial reinsurance market, with reinsurance limits and premiums equal to those of the insurance purchased by SCE, except for a contract for a premium of $93 million under which EIS provided insurance protection to SCE. SCE recorded the premium as insurance expense and recorded equal revenue due to customer funding through regulatory cost recovery mechanisms, therefore there was no earnings impact on SCE's consolidated statement of income. EIS recorded the premium as insurance revenue. On the Edison International consolidated statement of income, the EIS insurance revenue eliminated with SCE's insurance expense, therefore the SCE customer revenues increased the earnings of Edison International. The amount of insurance expense and corresponding revenue was $22 million for the three months ended March 31, 2023.

The related-party transactions included in SCE's consolidated balance sheets for wildfire-related insurance purchased from EIS and related expected insurance recoveries were as follows:

UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

2017/2018 Wildfire/Mudslide Events

Multiple lawsuits related to the 2017/2018 Wildfire/Mudslide Events naming SCE as a defendant have been filed by three categories of plaintiffs: individual plaintiffs, subrogation plaintiffs and public entity plaintiffs. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. The litigation could take a number of years to be resolved because of the complexity of the matters and number of plaintiffs.

As of April 25, 2023, SCE was aware of approximately 150 pending unsettled lawsuits, representing approximately 1,000 plaintiffs, related to the Thomas and Koenigstein Fires naming SCE as a defendant. Approximately 100 of the approximately 150 lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. One of the lawsuits was filed as a purported class action. The lawsuits, which have been filed in the superior courts of Ventura, Santa Barbara and Los Angeles Counties allege, among other things, negligence, inverse condemnation, trespass, private nuisance, and violations of the public utilities and health and safety codes. SCE and certain of the individual plaintiffs in the Thomas and Koenigstein Fire litigation have been pursuing settlements of claims under a mediation program adopted to promote an efficient and orderly settlement process. Some individual plaintiffs have opted to pursue trial outside of the settlement program.

Approximately 50 of the approximately 150 pending unsettled lawsuits mentioned in the paragraph above allege that SCE has responsibility for the Thomas and/or Koenigstein Fires and that the Thomas and/or Koenigstein Fires proximately caused the Montecito Mudslides, resulting in the plaintiffs' claimed damages. Many of the Montecito Mudslides lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. In addition to other causes of action, some of the Montecito Mudslides lawsuits also allege personal injury and wrongful death.

As of April 25, 2023, SCE was aware of approximately 350 currently pending unsettled lawsuits, representing approximately 3,000 plaintiffs, related to the Woolsey Fire naming SCE as a defendant. Approximately 300 of the 350 lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. At least one of the lawsuits was filed as a purported class action. The lawsuits, which have been filed in the superior courts of Ventura and Los Angeles Counties allege, among other things, negligence, inverse condemnation, personal injury, wrongful death, trespass, private nuisance, and violations of the public utilities and health and safety codes. SCE and certain of the individual plaintiffs in the Woolsey Fire litigation have been pursuing settlements of claims under a mediation program adopted to promote an efficient and orderly settlement process. Some individual plaintiffs may opt to pursue trial outside of the settlement program.

The Thomas and Koenigstein Fires and Montecito Mudslides lawsuits are being coordinated in the Los Angeles Superior Court. The Woolsey Fire lawsuits have also been coordinated in the Los Angeles Superior Court.
