MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Edison International is the parent holding company of SCE and Edison Energy Group. SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity to customers in an approximately 50,000 square mile area of southern California. Edison Energy Group is a holding company for Edison Energy which is engaged in the competitive business of providing energy services to commercial and industrial customers. Edison Energy's business activities are currently not material to report as a separate business segment. Except when otherwise stated, references to each of Edison International, SCE, or Edison Energy Group mean each such company with its subsidiaries on a consolidated basis. References to Edison International refer to the consolidated group of Edison International and its subsidiaries. References to Edison International Parent and Other refer to Edison International Parent and its competitive subsidiaries. Unless otherwise described, all the information contained in this report relates to both filers.

Edison International's earnings are prepared in accordance with GAAP. Management uses core earnings (losses) internally for financial planning and for analysis of performance. Core earnings (losses) are also used when communicating with investors and analysts regarding Edison International's earnings results to facilitate comparisons of the company's performance from period to period. Core earnings (losses) are a non-GAAP financial measure and may not be comparable to those of other companies. Core earnings (losses) are defined as earnings attributable to Edison International shareholders less non-core items. Non-core items include income or loss from discontinued operations and income or loss from significant discrete items that management does not consider representative of ongoing earnings, such as write downs, asset impairments and other

income and expense related to changes in law, outcomes in tax, regulatory or legal proceedings, and exit activities, including sale of certain assets and other activities that are no longer continuing.

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

Southern California began experiencing the impacts of the COVID-19 pandemic in the first quarter of 2020. The total impacts of the pandemic are still emerging and will vary depending on the severity of impacts on society and the economy of the US and California, but it may have a material impact on SCE's ability to execute its planned work, including wildfire mitigation and capital projects and on the liquidity, cash flows and results of operations of Edison International and SCE. Factors that may increase in severity or that may emerge to cause these impacts include lack of availability of company and contractor employees to perform their job functions, supply chain disruptions, stop-work orders and limitations on the ability to obtain permits for work from local governments, reduced electricity usage by commercial and industrial customers

partially offset by increased electricity usage by residential customers, non-payment due to the economic impacts on the customers served by SCE and narrower access to, or increased costs of accessing, bank and capital markets.

Decoupling revenue mechanisms allow for differences in revenue resulting from actual and forecast volumetric electricity sales to be collected from or refunded to ratepayers and therefore insulate SCE's earnings from reductions in electricity usage.

In March 2020, the governor of California announced a statewide emergency as part of the state's response to address the COVID-19 pandemic. As a result SCE established memorandum accounts with CPUC approval, effective March 2020, to track incremental costs associated with the emergency for recovery, subject to CPUC reasonableness reviews.

2021 General Rate Case

revisions to the application in November 2019 and February 2020, SCE had requested a revenue requirement of $7.6 billion.

In April and May 2020, intervenors to the 2021 GRC proceeding, including the CPUC Public Advocates Office ("Cal Advocates") and The Utility Reform Network ("TURN"), submitted testimony in response to SCE's revised application. Cal Advocates proposed reductions to 2021 operation and maintenance spending of $423 million or 15% of the total, and reductions to 2021 capital spending of $445 million or 9% of the total. TURN proposed reductions to 2021 operation and maintenance spending of $556 million or 17% of the total, and reductions to 2021 capital spending of $714 million or 14% of the total. The reductions to capital expenditures proposed by both parties included significant proposed reductions to SCE's Wildfire Covered Conductor Program. If adopted, the proposals of Cal Advocates and TURN would result in a 2021 revenue requirement of approximately $6.9 billion and $6.7 billion, respectively.

In June 2020, in its rebuttal testimony, SCE revised its requested 2021 revenue requirement to $7.5 billion, a $1.1 billion increase over the 2020 revenue requirement authorized in the 2018 GRC as updated for anticipated post test-year ratemaking changes. The rebuttal testimony proposed post test-year increases in 2022 and 2023 of $434 million and $500 million respectively. SCE's request excludes the revenue requirement associated with the approximately $1.6 billion of AB 1054 Excluded Capital Expenditures.

SCE expects a final decision on the application for the 2021 test year in the first quarter of 2021. If the final decision is received after January 1, 2021, SCE will request the CPUC to approve establishment of a memorandum account making the authorized revenue requirement changes effective January 1, 2021. SCE cannot predict the revenue requirement the CPUC will ultimately authorize or forecast the timing of a final decision.

The CPUC amended the proposed schedule for the proceeding in April 2020 by adding a fourth phase referred to as track 4, to address a third attrition year, 2024, introduced by a January 2020 decision of the CPUC in a separate proceeding. SCE is scheduled to submit its testimony for track 4 in May 2022. For more information on other tracks of the 2021 GRC see "—Wildfire Mitigation and Wildfire Insurance Expenses—2021 General Rate Case Wildfire Mitigation Memorandum Account Balances."

FERC Formula Rate

2019 FERC Formula Rate Settlement

In June 2020, SCE filed a settlement on its formula rates for the 2019 Formula Rate case ("2019 Formula Rate Settlement") that, if approved by the FERC, will establish SCE's FERC transmission revenue requirement for the 2019 FERC Settlement Period. SCE may seek to implement a new formula rate after the 2019 FERC Settlement Period. The settlement provides for a total ROE of 10.30% inclusive of CAISO and transmission incentive adders. The settlement also provides that SCE's capital

structure for purposes of its formula rate will reflect the higher of SCE's actual equity ratio or 47.50%. The transmission revenue requirement and rates that have been billed to customers prior to the implementation of the 2019 Formula Rate Settlement utilized a base ROE of 11.97%. SCE expects to true-up the excess amounts billed to customers through the operation of the Formula Rate in 2021 and 2022. SCE had been recognizing revenue based on the expected outcome of this settlement and the impact of recording the settlement was not material.

In December 2019, the CPUC filed a protest with the FERC alleging that $419 million of costs associated with SCE's Tehachapi Transmission Project are imprudent and should be disallowed from SCE's FERC rate base because these costs exceeded the maximum reasonable costs identified by the CPUC when it granted the project's certificate of public convenience and necessity. As part of the 2019 Formula Rate Settlement, the CPUC withdrew its protest effective as of July 27, 2020.

2021 FERC Formula Rate Annual Update

In July 2020, SCE provided its preliminary 2021 annual transmission revenue requirement update to interested parties. The update reflects an increase in SCE's transmission revenue requirement of $123 million or 12.8% higher than amounts included in the 2020 annual rates. The increase is primarily due to the impact of the 2019 FERC Formula Rate Settlement, which excluded certain refunds from the TO2018 settlement and growth in rate base. SCE expects to file its 2021 annual update with the FERC by December 1, 2020 with the proposed rates effective January 1, 2021.

Phase I Decision in Residential Rates OIR

In June 2020, the CPUC issued a final decision on the first phase of the ongoing proceeding Order Instituting Rulemaking to Consider New Approaches to Disconnections and Reconnections to Improve Energy Access and Contain Costs ("Residential Rates OIR"). This decision applies only to SCE's residential customers and requires the creation of an arrearage management program to forgive a portion of certain low income customers' past arrears as long as they remain current on monthly billing, prohibits use of establishment of credit or reestablishment of service deposits, and caps SCE's disconnection rate. SCE's disconnection rate will be capped at 8% in 2020 and will reduce by 1% each year until 2024.

The decision requires SCE to establish a two-way balancing account to reflect the actual costs of disconnections in customer rates and to establish a memorandum account to track the costs of implementing the decision.

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 is currently incurring wildfire mitigation and wildfire insurance related spending at levels significantly exceeding amounts authorized in its 2018 GRC. Several regulatory mechanisms, including but not limited to the GS&RP memorandum account, the FHPMA, the WMP memorandum account and the WEMA, exist to allow SCE to track and seek recovery of these incremental costs. In accordance with the accounting standards applicable to rate-regulated enterprises, SCE defers costs as regulatory assets that are probable of future recovery from customers. For certain wildfire mitigation and wildfire insurance expenses SCE performs its assessment of future recovery after its year to date spending exceeds the amounts authorized for the full calendar year under its current revenue requirement. As of June 30, 2020, SCE has recognized $549 million of regulatory assets related to incremental wildfire mitigation expenses, including depreciation expense from $1.1 billion of total incremental capital expenditures, and $484 million of regulatory assets related to incremental wildfire insurance expenses in the WEMA. While SCE believes such costs are probable of future recovery, there is no assurance that SCE will collect all amounts currently deferred as regulatory assets. SCE has recorded a further $165 million of incremental wildfire mitigation expenses, including $1 million in the quarter ending June 30, 2020, that are subject to reasonableness reviews through the GS&RP and the 2021 GRC proceedings.

Grid Safety and Resiliency Program

In April 2020, the CPUC approved a settlement agreement between SCE and certain parties to SCE's GS&RP proceeding. Under the settlement, SCE is authorized to spend approximately $526 million ($407 million capital) in 2018 dollars between 2018 and 2020. SCE will include the authorized revenue requirement in rates and establish a balancing account to track the difference between actual GS&RP costs and amounts authorized. If spending is less than authorized, SCE will refund those amounts to customers. If spending is in excess of forecasted amounts, or in excess of 115% of forecasted amounts for certain activities, SCE will present those costs for reasonableness review in the 2021 GRC. Additionally, SCE's recovery of tree removal costs is capped at a specific average authorized unit cost and a total volume of trees.

Through June 30, 2020, SCE has incurred $617 million of capital expenditures, of which $142 million will be subject to a reasonableness review, and $86 million of operations and maintenance expenses, all of which is within the amount authorized in the settlement agreement.

In July 2020, SCE applied for an irrevocable order from the CPUC to finance $337 million, comprised of AB 1054 Excluded Capital Expenditures incurred in connection with GS&RP and prudently incurred financing costs, through the issuance of securitized bonds.

2021 General Rate Case Wildfire Mitigation Memorandum Account Balances 

For purposes of evaluating SCE's recovery of 2018 – 2020 wildfire mitigation costs, the CPUC has incorporated additional tracks into the 2021 GRC proceeding. Under the adopted schedule, most incremental wildfire mitigation costs from 2018 and 2019 are to be reviewed in track 2. In March 2020, SCE made its 2021 GRC track 2 filing with the CPUC for review and approval of $302 million of capital expenditures and $509 million of operation and maintenance expenses incremental to amounts authorized in SCE's 2018 GRC and not associated with SCE's GS&RP application. The GRC track 2 expenditures predominantly related to enhanced overhead inspections, an expanded vegetation management program and expert consultant contract labor costs supporting SCE's wildfire mitigation activities. The majority of these expenditures are recorded in the WMP memorandum account and the FHPMA. The capital revenue requirement recorded in memorandum accounts mainly represents depreciation expense, taxes, and return. After flow through tax effects and excluding the revenue requirement associated with AB 1054 Excluded Capital Expenditures, the GRC track 2 filing resulted in an additional requested revenue requirement of $500 million.

Incremental wildfire mitigation costs from 2020, and all GS&RP costs above settled amounts, are to be reviewed in track 3 of the 2021 GRC proceeding, which will be filed in March 2021.

The schedule for SCE's 2021 GRC includes proposed decisions on track 2 and track 3 in the first quarters of 2021 and 2022, respectively.

RESULTS OF OPERATIONS

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

Impact of 2018 GRC

In May 2019, the CPUC approved a decision in SCE's 2018 GRC. The revenue requirements in the 2018 GRC decision were retroactive to January 1, 2018. SCE recorded the prior period impact of the 2018 GRC decision in the second quarter of 2019 including an increase to earnings of $131 million from the application of the decision to revenue, depreciation expense and income tax expense, of which $65 million was attributable to 2018 and $66 million was attributable to first quarter of 2019 and an impairment of utility property, plant and equipment of $170 million ($123 million after-tax) related to disallowed historical capital expenditures.

The following table is a summary of SCE's results of operations for the periods indicated.

Three months ended June 30, 2020 versus June 30, 2019

Earning Activities

Earning activities were primarily affected by the following:

Cost-recovery activities were primarily affected by the following:

Supplemental Operating Revenue Information

SCE's retail billed and unbilled revenue (excluding wholesale sales) was $2.7 billion and $2.6 billion for the three months ended June 30, 2020 and 2019 respectively, and $5.3 billion and $5.2 billion for the six months ended June 30, 2020 and 2019 respectively.

The increase for the three months and six months ended June 30, 2020 compared to the same periods in 2019 is primarily due to higher CPUC revenue due to the adoption of the 2018 GRC decision, partially offset by lower cost-recovery activities related to lower purchased power and fuel costs driven by contract amendments. In addition, the six months ended June 30, 2020 includes lower purchased power and fuel costs driven by lower power and gas prices. See "—Earnings Activities" and "—Cost-Recovery Activities" for further details.

As a result of the CPUC-authorized decoupling mechanism, SCE earnings are not affected by changes in retail electricity sales.

SCE's income tax benefit decreased by $94 million and $124 million for the three and six months ended June 30, 2020 compared to the same period in 2019.

The effective tax rates were 5.9% and (17.8)% for the three months ended June 30, 2020 and 2019, respectively. The effective tax rates were (8.0)% and (28.9)% for the six months ended June 30, 2020 and 2019, respectively. SCE's effective tax rate is below the federal statutory rate of 21% primarily due to 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 increase for the three months ended June 30, 2020 is primarily due to the absence of a tax benefit recorded in 2019 from the adoption of the 2018 GRC final decision. The effective tax rate increase for the six months ended June 30, 2020 is primarily due to the absence of tax benefit from the adoption of the 2018 GRC final decision and the absence of the 2019 changes in the allocation of deferred tax re-measurement between customers and shareholders that resulted from a CPUC resolution, partially offset by tax benefits from re-measurement of uncertain tax positions related to the 2010 – 2012 California state tax filings currently under audit.

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

Loss from Operations

The following table summarizes the results of Edison International Parent and Other:

The loss from operations of Edison International Parent and Other increased $36 million and $57 million for the three and six months ended June 30, 2020 compared to the same period in 2019.

The increase of losses for the three and six months ended June 30, 2020 is primarily due to a goodwill impairment charge of $34 million ($25 million after-tax) recorded in 2020 for Edison International Parent and Other related to Edison Energy stemming from the economic impact of COVID-19 and higher interest expense as a result of increased borrowings.

LIQUIDITY AND CAPITAL RESOURCES

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

The COVID-19 pandemic may cause narrower access to, or increased costs of accessing, bank and capital markets. As a precaution, in March and April 2020, SCE brought forward debt issuances that had been planned for later in the year to provide additional financing flexibility given possible future market uncertainty. For further details, see "Management Overview—COVID-19" and "—Available Liquidity."

In the next 12 months, SCE expects to fund its cash requirements through operating cash flows, capital market financings, and equity contributions from Edison International Parent, as needed. SCE also has availability under its credit facilities to fund cash requirements.

SCE expects to finance the approximately $1.6 billion of AB 1054 Excluded Capital Expenditures by issuing securitized bonds. For further information, see "Management Overview—Southern California Wildfires and Mudslides." Prior to issuance of such bonds, other debt instruments are being used to temporarily finance the expenditures, including a term loan of $475 million and a 364-day revolving credit facility for $800 million entered into during the first quarter of 2020.

SCE's credit ratings may be further 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. The broad economic impacts of the COVID-19 pandemic may also affect SCE's credit rating. For further information see "Management Overview—COVID-19" and "Risk Factors." 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 require SCE to pay related liabilities or post additional collateral if SCE's credit rating were to fall below investment grade from the major credit rating agencies. Incremental collateral requirements for power procurement contracts resulting from a potential downgrade of SCE's credit rating to below investment grade are $66 million as of June 30, 2020. In addition, if SCE's credit rating falls below investment grade, it may 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. Furthermore, if SCE was downgraded below investment grade, counterparties may also institute new collateral requirements for future transactions. For further details, see "—Margin and Collateral Deposits."

Available Liquidity

At June 30, 2020, SCE had cash on hand of $254 million.

At June 30, 2020, SCE had approximately $2.9 billion available under its $3.0 billion revolving credit facility. The credit facility is available for borrowing needs until May 2024 and may be extended for one additional year with the lenders' approval. The aggregate maximum principal amount under the credit facility may be increased up to $4.0 billion, provided additional lender commitments are obtained.

In the first quarter of 2020, SCE entered into a 364-day revolving credit facility for $800 million. The credit facility is available for borrowing needs until March 2021 and may be extended for two 364-day periods, at the lenders' discretion. The aggregate maximum principal amount under the revolving credit facility may be increased up to $1.1 billion, provided that additional lender commitments are obtained. At June 30, 2020, SCE had no borrowings under the facility. The facility is expected to fund future AB 1054 Excluded Capital Expenditures until an anticipated issuance of securitized bonds. In the first quarter of 2020, SCE also borrowed $475 million under a term loan agreement due in March 2021 to repay commercial paper borrowings temporarily used to fund AB 1054 Excluded Capital Expenditures.

In the second quarter of 2020, SCE entered into a 364-day revolving credit facility for $1.5 billion. The credit facility is available for borrowing needs until May 2021. At June 30, 2020, there were no borrowings under the revolving credit facility. The revolving credit facility is available for general corporate purposes, including to support liquidity needs that may arise as a result of undercollections due to the COVID-19 pandemic and related consumer protection measures that SCE has put in place.

In the first quarter of 2020, SCE issued a total of $1.7 billion of first and refunding mortgage bonds. The proceeds were used to repay SCE's commercial paper borrowings and repurchase tax-exempt pollution control bonds that were subject to mandatory redemption. SCE continues to hold the tax-exempt pollution control bonds and plans to re-market them subject to market conditions. In the second quarter of 2020, SCE issued $600 million of first and refunding mortgage bonds due in 2025. The proceeds were used to finance undercollections of revenues SCE is authorized to recover from customers through regulatory balancing accounts. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

SCE may finance balancing account undercollections and working capital requirements to support operations and capital expenditures with commercial paper, its credit facilities or other borrowings, subject to availability in the bank and capital markets. As necessary, SCE will utilize its available liquidity, capital market financings, other borrowings or parent company contributions to SCE equity in order to meet its obligations as they become due, including any potential costs related to the 2017/2018 Wildfire/Mudslide Events. For further information, see "Management Overview—Southern California Wildfires and Mudslides."

Debt Covenant

SCE's credit facilities and term loan require a debt to total capitalization ratio as defined in the applicable agreements of less than or equal to 0.65 to 1. At June 30, 2020, SCE's debt to total capitalization ratio was 0.48 to 1.

At June 30, 2020, SCE was in compliance with all financial covenants that affect access to capital.

Capital Investment Plan

Major Transmission Projects

Riverside Transmission Reliability Project

In October 2018, the CPUC issued an environmental report that identified a new route alternative, as the environmentally preferred project and proposed an additional underground section of the proposed 220-kV power line. In March 2020, the alternative project with revised scope and an updated cost of $584 million was approved by CPUC. The scheduled in-service date of the project has been extended from 2024 to 2026.

Eldorado-Lugo-Mohave Upgrade

SCE Dividends

CPUC holding company rules require that SCE's dividend policy be established by SCE's Board of Directors on the same basis as if SCE were a stand-alone utility company, and that the capital requirements of SCE, as deemed to be necessary to meet SCE's electricity service obligations, shall receive first priority from the Boards of Directors of both Edison International and SCE. In addition, the CPUC regulates SCE's capital structure which limits the dividends it may pay to its shareholders.

Effective January 1, 2020, the common equity component of SCE's CPUC authorized capital structure was increased from 48% to 52% on a weighted average basis over the January 1, 2020 to December 31, 2022 compliance period ("the Capital Structure Compliance Period"). For further information, see "Management Overview—2020 Cost of Capital Application" in the 2019 MD&A. Under AB 1054, the impact of SCE's contributions to the Wildfire Insurance Fund are excluded from the measurement of SCE's CPUC-jurisdictional authorized capital structure. For further information, see "Management Overview—Southern California Wildfires and Mudslides."

In May 2020, the CPUC issued a decision on SCE's application to the CPUC for waiver of compliance with its equity ratio requirement, that allows SCE to exclude from its equity ratio calculations (i) net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events and (ii) debt issued for the purpose of paying claims related to the 2017/2018 Wildfire/Mudslide Events up to an amount equal to the net charges accrued in connection with the 2017/2018 Wildfire/Mudslide Events. The temporary exclusion will lapse on May 7, 2022 or when a determination regarding cost recovery for the 2017/2018 Wildfire/Mudslide Events is made, whichever comes earlier. If the CPUC has not made a determination regarding cost recovery by May 7, 2022, SCE is permitted to file another application for a waiver of compliance with its equity ratio requirement. In the interim, SCE is required to notify the CPUC if an adverse financial event reduces SCE's spot equity ratio by more than one percent from the level most recently filed with the CPUC in the proceeding. The last spot equity ratio SCE filed with the CPUC in the proceeding did not exclude the $1.8 billion net charge and was 45.2% as of December 31, 2018 (at the time the common equity component of SCE's CPUC authorized capital structure was required to remain at or above 48% on a weighted average basis over the applicable 37-month period). SCE’s spot equity ratio on December 31, 2018 would have been 48.7% had the $1.8 billion net charge been excluded, therefore SCE will notify the CPUC if its spot ratio drops below 47.7% in any quarter. For further information, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides."

SCE monitors its compliance with the CPUC’s equity ratio requirement based on the weighted average of the common equity component of SCE’s CPUC authorized capital structure over the Capital Structure Compliance Period using its actual capital structure from the beginning of the Capital Structure Compliance Period through the reporting date together with forecasted performance and expected financing activities for the remainder of the Capital Structure Compliance Period. SCE expects to be compliant with its CPUC authorized capital structure at December 31, 2022.

As a California corporation, SCE's ability to pay dividends is also governed by the California General Corporation Law. California law requires that for a dividend to be declared: (a) retained earnings must equal or exceed the proposed dividend, or (b) immediately after the dividend is made, the value of the corporation's assets must exceed the value of its liabilities plus amounts required to be paid, if any, in order to liquidate stock senior to the shares receiving the dividend. Additionally, a California corporation may not declare a dividend if it is, or as a result of the dividend would be, likely to be unable to meet its liabilities as they mature. Prior to declaring dividends, SCE's Board of Directors evaluates available information, including when applicable, information pertaining to the 2017/2018 Wildfire/Mudslide Events, to ensure that the California law requirements for the declarations are met. On June 24, 2020, SCE declared a dividend to Edison International of $269 million.

The timing and amount of future dividends are also dependent on a number of other factors including SCE's requirements to fund other obligations and capital expenditures, its ability to access the capital markets, and generate operating cash flows and earnings. If SCE incurs significant costs related to catastrophic wildfires, including the 2017/2018 Wildfire/Mudslide Events, and is unable to recover such costs through insurance, the Wildfire Insurance Fund (for fires after July 12, 2019), or from customers or is unable to access capital markets on reasonable terms, SCE may be limited in its ability to pay future dividends to Edison International and its preferred and preference shareholders.

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 June 30, 2020 due to the addition of incremental power and energy procurement contracts with collateral requirements, if any, the impact of changes in wholesale power and natural gas prices on SCE's contractual obligations and the impact of SCE's credit ratings falling below investment grade.

Decommissioning of San Onofre

Due to the emergency circumstances involving the COVID-19 pandemic and related governmental orders restricting non-essential work activities, SCE has decided to delay commencing major decommissioning activities at San Onofre. SCE will assess the appropriate timing for commencing major decommissioning activities based in part on when governmental restrictions are relaxed. As of the date of this report, SCE is continuing fuel transfer operations and other critical work at San Onofre.

In March 2020, the CPUC approved disbursements from SCE's nuclear decommissioning trusts to cover forecasted 2020 decommissioning costs, of which SCE's share is $406 million.

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, including by issuing additional debt and equity, as needed. Edison International may finance its ongoing cash requirements, including common stock 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.

The COVID-19 pandemic may cause narrower access to, or increased costs of accessing, bank and capital markets. As a precaution, in March and April 2020, Edison International brought forward debt and equity issuances that had been planned for later in the year to provide additional financing flexibility given possible future market uncertainty. For further details, see "Management Overview—COVID-19."

At June 30, 2020, Edison International Parent had cash on hand of $270 million and no borrowings on its $1.5 billion revolving credit facility. The credit facility is available for borrowing needs until May 2024, and may be extended for one additional year with the lenders' approval. Under certain circumstances, the aggregate maximum principal amount under the credit facility may be increased up to $2.0 billion, provided additional lender commitments are obtained.

Edison International Parent and Other's liquidity and its ability to pay operating expenses and pay dividends to common shareholders are dependent on access to the bank and capital markets, dividends from SCE, realization of tax benefits and its ability to meet California law requirements for the declaration of dividends. Prior to declaring dividends, Edison International's Board of Directors evaluates available information, including when applicable, information pertaining to the 2017/2018 Wildfire/Mudslide Events, 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 "—SCE—SCE Dividends." Edison International intends to maintain its target payout ratio of 45% – 55% of SCE's core earnings, subject to the factors identified above.

Edison International Parent expects to make further capital contributions to SCE in 2020 to increase the common equity component of its capital structure, after deducting CPUC allowed exclusions, to 52% on a weighted average basis over the Capital Structure Compliance Period. For further information, see "—SCE—SCE Dividends."

Edison International Parent's credit facility requires a consolidated debt to total capitalization ratio as defined in the applicable agreements of less than or equal to 0.70 to 1. At June 30, 2020, Edison International Parent's consolidated debt to total capitalization ratio was 0.56 to 1.

At June 30, 2020, Edison International Parent was in compliance with all financial covenants that affect access to capital.

Edison International Parent's long-term issuer credit ratings remain at investment grade levels after downgrade actions taken by the major credit agencies in the first quarter of 2019. Edison International Parent's rating outlook has remained stable after the passage of AB 1054 and the establishment of the Wildfire Insurance Fund, which provided the Liability Cap and the new standard that the CPUC must apply when assessing the prudency of a utility. For further information, see "Management Overview—Southern California Wildfires and Mudslides."

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 further 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. The broad economic impacts of the COVID-19 pandemic may also affect Edison International's credit rating. For further information see "Management Overview—COVID-19" and "Risk Factors." 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.

Net Cash Provided by Operating Activities

Net cash provided by operating activities was impacted by the following:

Net cash outflow for working capital was $120 million and $235 million during the six months ended June 30, 2020 and 2019, respectively. Net cash outflow for working capital reduced from 2019 to 2020 due to insurance premium payments of $90 million and $431 million for wildfire-related coverage in 2020 and 2019, respectively. Net cash outflow for working capital in both periods was impacted by increases in receivables from customers including increases in accrued unbilled revenue of $245 million and $149 million in 2020 and 2019, respectively. Net cash outflow for working capital in 2019 was partially offset by an increase in accounts payable and accrued expenses of $170 million.

Net cash used in regulatory assets and liabilities, including changes in net undercollections of balancing accounts was $927 million and $543 million during the six months ended June 30, 2020 and 2019, respectively. SCE has a number of balancing 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:

2020

2019

Cash flows provided by (used in) other noncurrent assets and liabilities were primarily related to net earnings from nuclear decommissioning trust investments ($49 million in 2020 and $37 million in 2019, respectively) and SCE's payments of decommissioning costs ($98 million in both 2020 and 2019). See "Nuclear Decommissioning Activities" below for further discussion. Also includes wildfire related insurance recovery of $73 million in 2020.

Net Cash Provided by Financing Activities

The following table summarizes cash provided by financing activities for the six months ended June 30, 2020 and 2019. Issuances of debt are discussed in "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."

Net Cash Used in Investing Activities

Cash flows used in investing activities are primarily due to capital expenditures related to transmission and distribution investments ($2.5 billion and $2.2 billion for the six-month periods ended June 30, 2020 and 2019, respectively). In addition, SCE had a net redemption of nuclear decommissioning trust investments of $62 million and $72 million during the six months ended June 30, 2020 and 2019, respectively. See "Nuclear Decommissioning Activities" below for further discussion.

Nuclear Decommissioning Activities

SCE's statement of cash flows includes nuclear decommissioning activities, which are reflected in the following line items:

Net cash used in operating activities relates to interest and dividends less administrative expenses, taxes and SCE's decommissioning costs. See "Notes to Consolidated Financial Statements—Note 10. Investments" for further information. Investing activities represent the purchase and sale of investments within the nuclear decommissioning trusts, including the reinvestment of earnings from nuclear decommissioning trust investments. The net cash impact reflects timing of decommissioning payments $98 million in both 2020 and 2019 and reimbursements to SCE from the nuclear decommissioning trust ($111 million and $109 million in 2020 and 2019, respectively).

Edison International Parent and Other

The table below sets forth condensed historical cash flow from operations for Edison International Parent and Other, including intercompany eliminations.

Net Cash Used in Operating Activities

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

Net Cash Provided by Financing Activities

Net cash provided by financing activities was as follows:

SCE has contingencies related to wildfire and mudslide events, wildfire insurance, environmental remediation, nuclear insurance, spent nuclear fuel and the Tehachapi Transmission Project, which are discussed in "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies."

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 of counterparties based on credit ratings 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. Based on SCE's policies and risk exposures related to credit, SCE does not anticipate a material adverse effect on their financial statements as a result of counterparty nonperformance. At June 30, 2020, SCE's power and gas trading counterparty credit risk exposure was $34 million, which is associated with entities that have an investment grade rating of A or higher. SCE assigns a credit rating to counterparties based on the lower of a counterparty's S&P or Moody's rating. At June 30, 2020 the majority of SCE's power and gas trading counterparty credit risk exposure was to CAISO market participants. The broad economic impacts of the COVID-19 pandemic are still emerging and may increase credit risk across CAISO market participants, as of June 30, 2020, no impacts had been noted.
