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 income resulting from allocation of losses to tax equity investors under the HLBV accounting method 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 gains and losses related to certain tax, regulatory or legal settlements or proceedings, and exit activities, including sale of certain assets and other activities that are no longer continuing.
Edison International's first quarter 20182019 earnings decreased $144increased $60 million from the first quarter of 2017, comprised of a decline in SCE's earnings of $63 million and2018, resulting from an increase in Edison International Parent and Other's lossesearnings of $81$53 million and an increase in SCE's earnings of $7 million. SCE's earnings consisted of $72 million of higher non-core income and $65 million of lower core earnings. The decrease in core earnings resulted from the impact of the July 2017 cost of capital decision on GRC revenue, higher operation and maintenancewas primarily due to wildfire mitigation expenses and higher net financing costs.costs, partially offset by a 2018 refund to customers for prior overcollections.
Edison International Parent and Other's increase in lossesearnings for the three months ended March 31, 20182019 was primarily due to higherlower core losses of $37$9 million and higherlower non-core losses of $44 million. The increase inlower core losses waswere mainly due to lower income tax benefits related to stock option exercisescorporate expenses and decreased losses at the impact of Tax Reform on pre-tax losses.competitive businesses under Edison Energy Group.


Consolidated non-core items for the first quarter of 2019 and 2018 and 2017primarily included:
ImpairmentIncome tax benefits of $69 million recorded in 2019 for SCE related to changes in the allocation of deferred tax re-measurement between customers and shareholders as a result of a CPUC resolution issued in February 2019. The resolution determined that customers are only entitled to excess deferred taxes which were included when setting rates and other chargesdeferred tax re-measurement belongs to shareholders.
An impairment charge of $66 million ($48 million after tax)after-tax) recorded in 2018 for Edison International Parent and Other resulting from an agreement to sell SoCore Energy.
2018 General Rate Case
In February 2018, SCE updated its 2018 GRC application for the impact of Tax Reform resulting in a requested 2018 base rate revenue requirement of $5.534 billion, a decrease of $106 million over the 2017 GRC authorized revenue requirement.
In April 2019, the CPUC issued a 2018 GRC proposed decision, which if adopted, would result in a base rate revenue requirement of $5.102 billion in 2018, a decrease of $432 million from SCE's requested revenue requirement, primarily related to a reduction in authorized rate base, depreciation and operation and maintenance expenses. The proposed decision also identifies changes to certain balancing accounts, including the expansion of the TAMA to include the impacts of all differences between forecast and recorded tax expense. The proposed decision would also disallow certain historical spending, largely related to certain infrastructure replacement programs and corporate real estate.
The CPUC did not issue a decision on the 2018 GRC application during 2018 or during the first quarter of 2019, therefore SCE recognized revenue based on the 2017 authorized revenue requirement, adjusted for items SCE has determined to be probable of occurring, primarily the July 2017 cost of capital decision and Tax Reform. The CPUC has approved the establishment of a GRC memorandum account and the 2018 resulting fromand 2019 revenue requirements ultimately adopted by the CPUC will be effective as of January 1, 2018 and January 1, 2019, respectively. The proposed decision, if adopted as drafted, would have a significant impact on SCE and Edison International's agreementInternational’s reported results, including a non-core impairment of utility property, plant and equipment of up to sell SoCore Energy to a third party. The net assets of SoCore Energy have been recorded at fair value, less expected transaction costs (see "Results of Operations—Edison International Parent and Other—Strategic Review of Edison Energy Group Competitive Business—Sale of SoCore Energy").
Income of $6$257 million ($4185 million after-tax) related to disallowed historical capital expenditures and less than $1an increase to core earnings of approximately $130 million from application of the decision to revenue, depreciation and income tax expense retroactively for 2018 and the first quarter of 2019.
The proposed decision would allow a post-test year rate making mechanism that escalates capital additions by 2.49% for both 2019 and 2020. It would also allow operation and maintenance expenses to be escalated for 2019 and 2020 through the use of various escalation factors for labor, non-labor and medical expenses. The methodology set forth in the proposed decision would, if adopted by the CPUC, result in a revenue requirement of $5.422 billion in 2019 and $5.823 billion in 2020.
SCE will file comments on the proposed decision in May 2019 and SCE cannot predict when a final decision will be issued. A final decision could result in material changes to the proposed decision.
Capital Program
Total capital expenditures (including accruals) were $856 million and $853 million for the first quarterthree months of 2019 and 2018, respectively.
SCE's capital expenditure forecast for 2020 has been updated since the filing of the 2018 Form 10-K to reflect planned CPUC jurisdictional spending as informed by the 2018 GRC proposed decision and 2017, respectively,spending associated with SCE's wildfire mitigation-related capital expenditures under the GS&RP and WMP. The table below includes $346 million and a range of $500 million to $700 million of capital expenditures related to losses (netwildfire mitigation for 2019 and 2020, respectively. The CPUC has authorized tracking of distributions) allocatedcosts related to tax equity investors under the HLBV accounting method. Edison International core earnings reflectedGS&RP and WMP through memorandum accounts. SCE has also proposed a balancing account for its GS&RP spending. If SCE's proposed balancing account in its GS&RP application is approved, forecasted costs for the operating results ofGS&RP will be included in rates with a subsequent reasonableness review through the solar projects, related financingsannual ERRA proceeding. On April 29, 2018, the CPUC issued a proposed decision that, if adopted, would approve SCE's 2019 WMP and, among other things, would require SCE to meet certain reporting requirements. SCE continues to evaluate wildfire mitigation spending and anticipates that in 2019 the CPUC will issue decisions on the GS&RP and 2019 WMP. SCE expects to file its 2020 WMP by early 2020. SCE anticipates that wildfire mitigation spending not addressed in balancing accounts will be addressed in future GRC applications or through other regulatory proceedings.


SCE forecasts capital expenditures for 2019 – 2020 to be approximately $8,896 million to $9,096 million. SCE's 2019 – 2020 forecast for major capital expenditures are set forth in the table below:

SCE's authorized CPUC-jurisdictional rate base is determined through the GRC and other regulatory proceedings. Differences between actual and CPUC authorized capital expenditures are addressed in subsequent GRC or other regulatory proceedings. FERC-jurisdictional rate base is generally determined based on actual capital expenditures.

A final CPUC decision could result in material changes to the tax equity investor. The losses allocated toproposed decision, including the tax equity investor under HLBV accounting method results in income allocated to subsidiaries of Edison International, neither of which is due to the operating performance of the projects but rather due to the allocation of income tax attributes under the tax equity financing. Accordingly, Edison International has included the non-operating allocation of income as a non-core item. For further information on HLBV, see Note 1 of "Notes to Consolidated Financial Statements" includedweighted average annual rate base for 2018 – 2020 set forth in the 2017 Form 10-K.table above.
Southern California Wildfires and Mudslides
Approximately 35% of SCE's service territory is in areas identified as high fire risk by SCE. Multiple factors have contributed to increased wildfires, faster progression of wildfires and the increased damage from wildfires across SCE's service territory and throughout California. These include the buildup of dry vegetation in areas severely impacted by years of historic drought, lack of adequate clearing of hazardous fuels by responsible parties, higher temperatures, lower humidity, and strong Santa Ana winds. At the same time that wildfire risk has been increasing in Southern California, residential and commercial development has occurred and is occurring in some of the highest-risk areas. Such factors can increase the likelihood and extent of wildfires.
In December 2017 severaland November 2018, wind-driven wildfires (the "December 2017 Wildfires") impacted portions of SCE's service territory, and causedcausing substantial damage to both residential and business properties and service outages for SCE customers. The investigating government agencies, the VCFD and CAL FIRE, have determined that the largest of the 2017 fires originated on December 4, 2017, in the Anlauf Canyon area of Ventura County (the investigating agencies refer to this fire as the "Thomas Fire"), followed shortly thereafter by the Koenigstein Fire. While the progression of these two fires remains under review, the December 4, 2017 fires eventually burned substantial acreage in both Ventura and Santa Barbara Counties. The largest of the November 2018 fires, known as the ThomasWoolsey Fire, originated in Ventura County and burned acreage located in both Ventura and Santa BarbaraLos Angeles Counties. According to
In March 2019, the most recent California Department of ForestryVCFD and Fire Protection ("Cal Fire") incident informationCAL FIRE issued separate reports finding that the Thomas Fire burned over 280,000 acres, destroyed an estimated 1,063 structures, damaged an estimated 280 structures and resultedthe Koenigstein Fire were each caused by SCE equipment. 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 one fatality.the Anlauf Canyon area emerging in advance of the start time of the Thomas Fire indicated in the Thomas Fire report, 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 has previously disclosed that SCE believed its equipment was associated with the ignition of the Koenigstein Fire. SCE is continuing to assess the progression of the Thomas and Koenigstein Fires and the extent of damages that may be attributable to each fire.
Determining wildfire originMultiple lawsuits related to the Thomas and cause is oftenKoenigstein Fires and the Woolsey Fire have been initiated against SCE and Edison International. Some of the Thomas and Koenigstein Fires lawsuits claim that SCE and Edison International have responsibility for the damages caused by the Montecito Mudslides based on a complextheory that SCE has responsibility for the


Thomas and/or Koenigstein Fires and time-consuming process, and several investigationsthat the Thomas and/or Koenigstein Fires proximately caused the Montecito Mudslides.
SCE's internal review into the facts and circumstances of each of the 2017/2018 Wildfire/Mudslide Events is ongoing, and SCE expects to obtain and review additional information and materials in the possession of third parties during the course ofits internal reviews and the litigation processes. Final determinations of liability for the Thomas Fire, the Koenigstein Fire, the Montecito Mudslides and the Woolsey Fire (each a "2017/2018 Wildfire/Mudslide Event," and, collectively, the "2017/2018 Wildfire/Mudslide Events"), including determinations of whether SCE was negligent, would only be made during lengthy and complex litigation processes.
Even when investigations are believedstill pending or liability is disputed, an assessment of likely outcomes, including through future settlement of disputed claims, may require a liability to be ongoing.accrued under accounting standards. Based on information available to SCE has been advised that the origins and causesconsideration of the fire are being investigated by Cal Fire and the Ventura County Fire Department. In connectionrisks associated with its investigation of the Thomas Fire, Cal Fire has removed and retained certain of SCE's equipment that was located near suspected ignition points of the fire. The CPUC's SED is also conducting an investigation to assess the compliance of SCE and its facilities with applicable rules and regulations in areas impacted by the Thomas Fire. In addition, as it does in all wildfire matters in which its facilities may or are alleged to be involved, SCE is conducting its own investigation of the Thomas Fire. At this time, SCE cannot predict when its own investigation, or the investigations of Cal Fire, the Ventura County Fire Department or the SED, will be completed.
SCE is aware of multiple lawsuits filed related to the Thomas Fire naming SCE as a defendant. Several of the lawsuits also name Edison International as a defendant. Certain California courts have previously found utilities to be strictly liable for property damage, regardless of fault, by applying the theory of inverse condemnation when a utilities’ facilities were determined to be a substantial cause of a wildfire that caused property damage. Any potential liability for December 2017 Wildfire-related damages will depend on a number of factors, including whether SCE substantially caused, or contributed to, the damages and whether parties seeking recovery of damages will be required to show negligence in addition to causation.
Given the preliminary stages of the investigations and the uncertainty as to the causes of the Thomas Fire, and the extent and magnitude of potential damages,litigation, Edison International and SCE are currently unableexpect to predictincur a material loss in connection with the outcome2017/2018 Wildfire/Mudslide Events and accrued a liability of $4.7 billion in the fourth quarter of 2018. This liability corresponds to the lower end of the claims made against SCE and Edison International or reasonably estimate aestimated range of expected potential losses that may be incurred. SCEincurred in connection with the 2017/2018 Wildfire/Mudslide Events and Edison International’s potential liability related to the Thomas Fire could be substantial.
SCE has approximately $1 billion of wildfire-specific insurance coverage,is subject to a self-insured retention of $10 million per occurrence, for wildfire-related claims for the period ending on May 31, 2018. SCE also has approximately $300 million ofchange as additional insurance coverage for wildfire-related occurrences for the period from December 31, 2017 to December 31, 2018, which may be used in addition to the $1 billion in wildfire insurance for wildfire events occurring on or after December 31, 2017 and on or before May 31, 2018, and would be available for new wildfire events, if any, occurring after May 31, 2018 and on or before December 30, 2018. Various coverage limitations within the policies that make up SCE's wildfire insurance coverage could result in material self-insured costs in the event of multiple wildfire occurrences during a policy period. Should responsibility for a significant portion of the damages related to the December 2017 Wildfires be attributed to SCE, SCE's insurance may not be sufficient to cover all such damages. In addition, SCE may not be authorized to recover its uninsured damages through electric service rates if, for example, the CPUC finds that the damages were incurred because SCE was not a prudent manager of its facilities.


information becomes available.
Edison International and SCE will seek to offset any actual losses realized in connection with the 2017/2018 Wildfire/Mudslide Events with recoveries from insurance policies in place at the time of the events and, to the extent actual losses exceed insurance, through electric rates. In the fourth quarter of 2018, Edison International and SCE also recorded expected recoveries from insurance of $2.0 billion and expected recoveries through FERC electric rates of $135 million, which is the FERC portion of the $4.7 billion liability it accrued. SCE believes that, in light of the CPUC'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 CPUC will interpret and apply its prudency standard to an investor-owned utility in future wildfire cost-recovery proceedings. Accordingly, 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 pursuingprobable of recovery through electric rates.
Edison International and SCE continue to pursue legislative, regulatory and legal strategies to address the application of a strict liability standard to wildfire-related damages without the ability to recover resulting damagescosts in electric rates. In April 2019, a strike force formed by California Governor Gavin Newsom released a report entitled Wildfires and Climate Change: California's Energy Future, which sets forth, among other things, guiding principles for potential reform to California policies regarding wildfire liability. While this report recommended that the Commission on Catastrophic Wildfire Cost and Recovery, the California legislature and the strike force continue working to develop a solution for consideration by the Governor and the legislature, Edison International and SCE cannot predict whether or when there will be a comprehensive solution mitigating the significant risk faced by a California investor-owned utilityutilities related to wildfires will be achieved.wildfires.
In April 2019, in addition to other requested increases in CPUC and FERC ROE, SCE requested from both the CPUC and FERC an additional 6% ROE to compensate investors for current wildfire risk. SCE would seek to reduce or remove this additional ROE if there is a material reduction in its wildfire cost recovery risk due to regulatory or legislative reform.

Montecito Mudslides
In January 2018, torrential rains in Santa Barbara County produced mudslides and flooding in Montecito and surrounding areas (the "Montecito Mudslides"). According to Santa Barbara County initial reports, the Montecito Mudslides destroyed an estimated 135 structures, damaged an estimated 324 structures and resulted in at least 21 fatalities, with two additional fatalities presumed.
Of the lawsuits mentioned above, several allege that SCE has responsibility for the Thomas Fire and that the Thomas Fire proximately caused the Montecito Mudslides, resulting in the plaintiffs' claimed damages. Some of the Montecito Mudslides lawsuits also name Edison International as a defendant. Edison International and SCE are currently unable to predict the outcome of the claims made against SCE and Edison International or reasonably estimate a range of losses that may be incurred. SCE and Edison International's potential liability related to the Montecito Mudslides could be substantial, SCE's insurance may not be sufficient to cover such damages, and SCE may not be authorized to recover any uninsured damages in rates.

Permanent Retirement of San Onofre
Entry into Revised Settlement and Utility Shareholder Agreements
As discussed in the year-ended 2017 MD&A, on January 30, 2018, the OII Parties entered into a Revised San Onofre Settlement Agreement in the CPUC OII proceeding regarding the steam generator replacement project at San Onofre and the related outages and subsequent shutdown of San Onofre. If approved by the CPUC, the Revised San Onofre Settlement Agreement will resolve all issues under consideration in the San Onofre OII and will modify the Prior San Onofre Settlement Agreement. If approved by the CPUC, the Revised San Onofre Settlement Agreement will also result in the dismissal of a federal lawsuit currently pending in the Ninth Circuit Court of Appeals challenging the CPUC's authority to permit rate recovery of San Onofre costs. The Revised San Onofre Settlement Agreement was the result of multiple mediation sessions in 2017 and January 2018 and was signed on January 30, 2018 following a settlement conference in the OII, as required under CPUC rules.
Implementation of the terms of the Revised San Onofre Settlement Agreement is subject to the approval of the CPUC, as to which there is no assurance. The OII Parties have agreed to exercise their best efforts to obtain CPUC approval, but there can be no certainty of when or what the CPUC will actually decide.
The San Onofre OII Assigned Commissioner and Assigned ALJ have issued joint rulings that, among other things, (i) direct the parties to submit joint testimony to the CPUC in support of the Revised San Onofre Settlement Agreement on April 27, 2018; (ii) direct all parties to submit briefing on whether an attorneys' fees provision in a related settlement agreement pertaining to the dismissal of a federal lawsuit challenging the Prior San Onofre Settlement Agreement impacts the integrity of the CPUC's intervenor compensation program; and (iii) schedule a public participation hearing and a status conference. In lieu of the joint testimony, with the ALJ's consent, the parties submitted a joint stipulation of facts in support of the Revised San Onofre Settlement Agreement on April 27, 2018.


Capital Program
Total capital expenditures (including accruals) were $853 million and $647 million for the first three months of 2018 and 2017, respectively. SCE's first quarter capital spending was consistent with its 2018 plan and SCE continues to project 2018 capital expenditures of approximately $4.2 billion for 2018. As discussed in the year-ended 2017 MD&A in the absence of a 2018 GRC decision, SCE has developed, and is executing against, a 2018 capital expenditure plan that will allow SCE to ramp up its capital spending program over the three-year GRC period to meet what is ultimately authorized in the 2018 GRC decision while minimizing the associated risk of unauthorized spending. Forecasted expenditures for capital projects are subject to change due to, among other things, timeliness of permitting, licensing, regulatory approvals, and contractor bids. For further information regarding the capital program see "Liquidity and Capital Resources—SCE—Capital Investment Plan" and the year-ended 2017 MD&A, "Management Overview—Capital Program."
Distribution Grid Development
Transportation Electrification Plan
In January 2017, SCE filed a transportation electrification plan with the CPUC to accelerate the adoption of electric transportation, which is critical to California's climate change and GHG reduction objectives. The plan proposes a five-year program to fund medium- and heavy-duty vehicle charging infrastructure that follows the model developed for SCE's Charge Ready program. The proposal has an estimated five-year cost of $554 million ($532 million capital) in 2016 dollars. In March 2018, the CPUC issued a proposed decision granting SCE $208 million in 2016 dollars to install the charging infrastructure at a minimum of 700 sites to support the electrification of at least 6,500 medium-and-heavy-duty electric vehicles. If adopted as proposed, the decision will allow customers the option to own the charging infrastructure, which would reduce the costs it can attribute to capital spending. SCE has filed comments on the proposed decision opposing treating customer-owned charging infrastructure as an expense and advocating to remove minimum site requirements based on incorrect cost estimates. SCE expects a final decision in the second quarter of 2018. SCE plans to propose additional programs and pilots in the future. The capital costs for these proposed projects are not included in SCE's capital spending and rate base forecasts.
2018 General Rate Case
As discussed in the year-end 2017 MD&A, in December 2017 SCE filed an update in the GRC proceedings for the three-year period 2018 – 2020. SCE updated its 2018 revenue requirement request from $5.885 billion to $5.673 billion, a $33 million increase over the 2017 GRC authorized revenue requirement, and proposed post-test year increases in 2019 and 2020 of $477 million and $554 million, respectively. In February 2018, SCE further updated its request to incorporate the changes associated with Tax Reform, which resulted in a revenue requirement request of $5.534 billion, a decrease of $139 million from the December update filing and a $106 million decrease from the 2017 GRC authorized revenue requirement. SCE proposed post-test year increases in 2019 and 2020 of $292 million and $319 million, respectively, decreases from the December update filing of $185 million and $235 million, respectively.
A final 2018 GRC decision is not expected until later in 2018. Until a GRC decision is issued, SCE is recognizing revenue in 2018 based on the 2017 authorized revenue requirement, adjusted for the July 2017 cost of capital decision and Tax Reform. The CPUC has approved the establishment of a GRC memorandum account, which will make the 2018 revenue requirement adopted by the CPUC effective as of January 1, 2018. SCE cannot predict the revenue requirement the CPUC will authorize or provide assurance on the timing of a final decision.
RESULTS OF OPERATIONS
Southern California Edison Company
SCE's results of operations are derived mainly through two sources:
Earning activities – representing revenue authorized by the CPUC and FERC, which is intended to provide SCE a reasonable opportunity to recover its costs and earn a return on its net investment in generation, transmission, and distribution assets. The annual revenue requirements are comprised of authorized operation and maintenance costs, depreciation, taxes, and a return consistent with the capital structure. Also, included in earnings activities are revenuesrevenue 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. 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), and certain operation and maintenance expenses. SCE earns no return on these activities.

Earning Activities
Earning activities were primarily affected by the following:
LowerHigher operating revenue of $39$37 million primarily due to the following:
A decreaseAn increase of $36$26 million in CPUC revenue primarily related to recognizing revenue based on the 2017 authorized revenue requirement, adjusted for the July 2017 cost of capital decision and the impact of Tax Reform. See "Management Overview—2018 General Rate Case" for further information.
A decrease in FERC revenue of $15a $16 million primarily due to the reduction in the federal corporate income tax rate resulting from Tax Reform.
A decrease in revenue of $10 million related to $18 million resulting from the amortization of excess deferred tax assets as a result of Tax Reform (offset in income taxes below) partially offset by $8 million of lower 2018 incremental tax benefits refundedrefund to customers (offset in income taxes below). See the year-end 2017 MD&A, "Management Overview—Tax Reform"2018 for further information.
In 2017, revenue related to San Onofre were reduced by $22 million, resulting from a $65 million reduction related to the tax abandonment of San Onofre (offset in income taxes below) partially offset by revenue of $43prior overcollections and $6 million related to the recoveryincremental return on rate base recorded through the pole loading balancing account.
An increase of amortization of the San Onofre regulatory asset$11 million in FERC revenue primarily due to higher operating costs subject to balancing account treatment (offset in operation and authorized return as provided by the Prior San Onofre Settlement Agreement. There is no revenue recorded in 2018 for San Onofre as a result of the Revised San


Onofre Settlement Agreement (see "Management Overview—Permanent Retirement of San Onofre" for further information)maintenance expenses and interest expense below).
Higher operation and maintenance costs of $59$80 million primarily due to wildfire mitigation costs, including enhanced overhead inspections, and other preventative maintenance costs.
Higher depreciation and amortization expense of $21 million primarily related to transmission and distribution investments.
Higher interest expense of $23 million primarily due to increased borrowings and higher interest on balancing account overcollections.
Lower other income and expense of $5 million primarily due to lower AFUDC equity income.
Higher income tax benefits of $99 million primarily due to higher insurance premiums associated with additional wildfire insurance coverage entered into in December 2017, higher transmission and distribution costs for line clearing and other maintenance expenses.
Lower depreciation and amortization expensenon-core income tax benefits of $38$69 million primarily related to changes in the amortizationallocation of the San Onofre regulatory asset in 2017 (offset in revenue above)deferred tax re-measurement between customers and lower intangible plant amortization.
Higher propertyshareholders and other taxes of $8 million primarily due to higher assessed values for property taxes in 2018.
Higher interest expense of $14 million primarily due to increased borrowings.
Lower income tax expense of $18 million primarily due to lower pre-tax income, for the first quarter of 2018 at a lower federal income tax rate partially offset by higher tax benefits in 2017 primarily related to the ratemaking treatment on the San Onofre tax abandonment. In addition, SCE had lower tax benefits refunded to customers in 2018 offset by tax benefits from the amortization of excess deferred tax assets as a result of Tax Reform (offset in revenue above). See the year-end 2017 MD&A, "Management Overview—Tax Reform" for further information.excluding non-core items.
Cost-Recovery Activities
Cost-recovery activities were primarily affected by the following:
Higher purchased power and fuel costs of $142$79 million primarily driven by higher power and gas prices, lower congestion revenue right credits and volume experienced in 2018 relative to 2017,higher charges from contract amendments, partially offset by lower load related to cooler weather and higher congestion revenue right credits.realized gains on hedging activities.
Higher operation and maintenance expensecosts of $12$138 million primarily driven by the authorization to recover 2018 wildfire insurance costs that had been deferred as regulatory assets and higher transmission access charges, partially offset by lower spending on various public purpose programs.programs and transmission access charges.
HigherLower other income and expensesexpense of $17$8 million primarily driven by higherlower net periodic benefit income -related to the non-service cost components in 2018 relative to 2017.for SCE's other post-retirement benefit plans. See "Notes to Consolidated Financial Statements—Note 9. Compensation and Benefit Plans" for further information.
Supplemental Operating Revenue Information
SCE's retail billed and unbilled revenue (excluding wholesale sales) was $2.4$2.6 billion and $2.3$2.4 billion for the three months ended March 31, 20182019 and 2017,2018, respectively.
Retail billedThe 2019 revenue increase is primarily related to higher cost-recovery activities related to 2018 wildfire insurance costs and unbilledhigher purchased power and fuel costs driven by higher power and gas prices, lower congestion revenue right credits and higher charges from contract amendments, partially offset by lower load related to cooler weather. See "—Cost-Recovery Activities" for the three months ended March 31, 2018 was higher compared to the same period in 2017 primarily due to the implementation of the 2018 ERRA rate increase.further details.
As a result of the CPUC-authorized decoupling mechanism, SCE earnings are not affected by changes in retail electricity sales (see "Business—SCE—Overview of Ratemaking Process" in the 2017 Form 10-K).sales.


Income Taxes
SCE's income tax expense decreasedbenefit increased by $18$99 million for the three months ended March 31, 20182019 compared to the same periodsperiod in 2017.2018.
The effective tax rates were (1.9)(48.2)% and 3.1%(1.9)% for the three months ended March 31, 20182019 and 2017,2018, respectively. SCE's effective tax rate is below the federal statutory rate of 21% and 35% for the three months ended March 31, 2018 and 2017, respectively, 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 decrease for the three months ended March 31, 2018 wasis primarily due to lower pre-tax income atthe change in the allocation of excess deferred tax re-measurement between customers and shareholders as a lower federal tax rate partially offset by higher tax benefitsresult of a CPUC resolution issued in 2017 primarily related to the ratemaking treatment on the San Onofre tax abandonment.February 2019.

Edison International Parent and Other
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.
Strategic Review of Edison Energy Group Competitive Businesses
Sale of SoCore Energy
On February 28, 2018, Edison International agreed to sell SoCore Energy LLC ("SoCore Energy"), a then subsidiary of Edison Energy Group, to a third party, subject to the completion of closing conditions, which were subsequently satisfied on April 16, 2018. As a result, Edison International accounted for the assets and liabilities of SoCore Energy as held for sale as of March 31, 2018 and recognized a pre-tax loss of $66 million ($48 million after-tax). See "Notes to Consolidated Financial Statements—Note 10. Investments" for further information.

LIQUIDITY AND CAPITAL RESOURCES
Southern California Edison CompanySCE
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, and any dividend payments to and equity contributions from Edison International, andobligations to preferred and preference shareholders, and the outcome of tax and regulatory matters.
In the next 12 months, SCE expects to fund its cash requirements through operating cash flows, tax benefits, and capital market financings, of debt and preferred equity contributions from Edison International, as needed. SCE also has availability under its credit facility to fund cash requirements.
SCE's long-term issuer credit ratings remain at investment grade levels after downgrade actions taken by the major credit agencies in March 2019. The following table summarizes SCE's current, long-term issuer credit ratings and outlook from the major credit rating agencies:
Moody'sFitchS&P
Credit RatingBaa2BBB-BBB
OutlookNegativeWatch NegativeWatch Negative
SCE's credit ratings may be further affected by the ultimate outcome of pending enforcement and litigation matters, including the outcome of the uncertainties and potential liabilities associated with the 2017/2018 Wildfire/Mudslide Events, and the reform of policies allocating liability to investor-owned utilities for damages caused by catastrophic wildfires substantially caused by utility equipment. 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 rating 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 is $14 million as of March 31, 2019. 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. For further details, see "— Margin and Collateral Deposits."
Available Liquidity
At March 31, 2018,2019, SCE had approximately $2.58$2.8 billion available under its $2.75$3.0 billion credit facility. The credit facility is available for borrowing needs until July 2022. In March 2018,May 2023 and contains two 1-year extension options. SCE borrowed $750 million under a term loan in February 2019 and issued $1.25$1.1 billion of first and refunding mortgage bonds.bonds in March 2019. The proceeds from these bondsthe term loan and the March 2019 bond issuances were used to repay commercial paper borrowings and for general corporate purposes. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."
In April 2019, Edison International contributed $750 million to SCE, which SCE used to repay its February 2019 term loan discussed above.
SCE may finance balancing account undercollections and working capital requirements to support operations and capital expenditures with commercial paper, its credit facility or other borrowings, subject to availability in the bank and capital markets. As necessary, SCE will utilize its available liquidity, capital market financings, of debt and preferred equityother 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 December 2017 Wildfires and Montecito Mudslides2017/2018 Wildfire/Mudslide Events (see "Management Overview—Southern California Wildfires"Wildfires and "—Montecito Mudslides" for further information).


Debt Covenant
A debt covenant in SCE's credit facility limits its debt to total capitalization ratio to less than or equal to 0.65 to 1. At March 31, 2018,2019, SCE's debt to total capitalization ratio was 0.450.52 to 1.
At March 31, 2018,2019, SCE was in compliance with all other financial covenants that affect access to capital.
Capital Investment Plan
Below are updates for large transmission and substation projects since the filing of the 2017 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 2017 MD&A.
Major Transmission Projects
Alberhill SystemEldorado-Lugo-Mohave Upgrade
The Alberhill System Project would consist of constructing a new 500-kV substation, two 500-kV transmission lines to connect the proposed substation to the existing Serrano-Valley 500-kV transmission line, telecommunication equipment and subtransmission lines in unincorporated and incorporated portions of western Riverside County. The Project was designed to meet long-term forecasted electrical demand in the proposed Alberhill Project area and to increase electrical system reliability. In April 2018, the CPUC issued a proposed decision denying SCE’s request2019, SCE filed an amended application for a certificate of public convenience and necessity basedwith the CPUC, which included total project costs of $257 million, an increase of $24 million to the previous estimate.
Regulatory Proceedings
2020 Cost of Capital Application
In April 2019, SCE filed its application with the CPUC for authority to establish its authorized cost of capital for utility operations for a three-year term, beginning January 1, 2020. In its application, SCE seeks a return on common equity of 10.60% for 2020 ("CPUC Base ROE"), compared to its current CPUC ROE of 10.30%. In addition to this CPUC Base ROE, SCE seeks an additional ROE of 6% to compensate investors for current wildfire risk ("CPUC Wildfire Risk ROE"). SCE would seek to reduce or remove this CPUC Wildfire Risk ROE if there is a material reduction in its wildfire cost recovery risk due to regulatory or legislative reform.
SCE also seeks to modify its current capital structure to increase the presiding administrative law judge's conclusion that the Alberhill System Projectcommon equity component of its capital structure from its current authorized level of 48% to 52% in 2020 and correspondingly reduce its preferred equity from 9% to 5%. If this change is not needed.approved, SCE continuesseeks a higher CPUC Base ROE of 10.9% to believeaccount for the Alberhill System Project is neededincreased leverage. SCE does not propose to serve forecasted local area demandchange its currently authorized level of long-term debt of 43%. In the application, SCE projects a cost of long-term debt of 4.74% and to increase operating flexibility. SCE has filed comments requestingan embedded cost of preferred equity of 5.70% and requests that the CPUC denyauthorize these costs for 2020. Based on the capital structure and cost factors discussed above, SCE proposes a weighted average return on rate base of 10.96% for 2020.


SCE proposes to maintain the current Cost of Capital Mechanism ("CCM"), which provides for an automatic modification of ROE, long-term debt and preferred equity costs in intervening years based on fluctuations in interest rates. In its application, SCE proposes to change the CCM so that it only applies to CPUC Base ROE, not to the CPUC Wildfire Risk ROE.
Assuming that the revenue requirement in SCE's pending 2018 GRC request, including the proposed decisionpost-test year ratemaking mechanism, is adopted, SCE's proposed cost of capital and capital structure will result in a projected revenue requirement increase in 2020 of approximately $1.2 billion from revenue currently included in electric rates of $11.1 billion.

FERC Formula Rate
2018 Formula Rate
The formula rate that SCE filed in 2017, with a January 1, 2018 effective date, is still pending resolution and is currently in settlement discussions. As a result, SCE's 2018 FERC rates remain subject to refund.
2019 Formula Rate
In April 2019, SCE filed an application with FERC to amend the formula rate associated with its transmission facilities in 2019. In the revised formula rate, SCE seeks a base return on equity of 17.12% ("FERC Base ROE"), compared to its proposed base ROE of 10.30% for its 2018 formula rate. The requested FERC Base ROE reflects a conventional ROE of 11.12% and an additional ROE of 6% to compensate investors for current wildfire risk. SCE would seek to reduce or remove the additional wildfire risk ROE if there is a material reduction in its wildfire cost recovery risk due to regulatory or legislative reform. SCE's total ROE request, inclusive of project incentives and a 0.5% incentive for CAISO participation, is approximately 18.4%.
If the new formula rate is accepted by FERC, it will supersede the existing formula rate, including the 2019 annual update, and could become effective as currently proposedearly as 60 days from the filing date. FERC has the authority to, and instead grantmay, suspend new rates for up to five months. If the certificate of public convenience and necessity fornew formula rate is suspended by FERC, the Alberhill System Project. A final CPUC decision is anticipated2019 transmission revenue requirement rate established in 2018. SCE is unablethe 2019 annual update will continue to predictbe effective, subject to refund, from January 1, 2019 until the outcome of this matter.
Approximately 48%end of the Alberhill System Project costs spent to datesuspension of the new formula rate. The new formula rate would likely be subject to recovery through CPUC revenue and 52% through FERC revenue. In October 2017, SCE obtained approvalrefund from the FERC for abandoned plant treatment for the Alberhill System Project, which allows SCE to seek recovery of 100% of all prudently-incurred costs after the approval date and 50% of prudently incurred costs prior to the approval date. Excluding land costs, which may be recovered through sale to a third party, SCE has incurred $39 million of capital expenditures, including overhead costs, as of March 31, 2018, of which $29 million may not be recoverable if the project is cancelled. SCE's total capital expenditures for the Alberhill System Project are estimated to be $486 million, of which approximately $175 million is included in the 2018 – 2020 capital program period.
Riverside Transmission Reliability
The Riverside Transmission Reliability Project is a joint project between SCE and Riverside Public Utilities (RPU), the municipal utility departmentend of the City of Riverside. While RPU would be responsible for constructing some ofsuspension until it is ultimately approved by FERC.
If the Project's facilities within Riverside,revised formula rate becomes effective on June 12, 2019 (the effective date requested by SCE), SCE's portion of the Project consists of constructing upgradesproposed revisions to its system, includingformula rate will result in a new 230-kV Substation; certain interconnection and telecommunication facilities andprojected increase in its retail base transmission linesrevenue requirement in 2019 of approximately $290 million from the citiescurrently effective retail base transmission revenue requirement of Riverside, Jurupa Valley and Norco and in portions of unincorporated Riverside County. The purpose of the Project is to provide RPU and its customers with adequate transmission capacity to serve existing and projected load, to provide for long-term system capacity for load growth, and to provide needed system reliability. 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. In April 2018, the CPUC issued a subsequent environmental impact report which included a new route alternative, different from SCE’s proposed project, as the environmentally preferred project and proposed an additional 220-kV underground power line. SCE is assessing the potential cost impacts of the new route alternative and underground power line. SCE expects a CPUC decision in late 2018 or early 2019.approximately $1 billion.
Dividend RestrictionsSCE Dividends
On January 31, 2018,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 paidwere 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 a dividend of $212 million that was declared duringand SCE. In addition, the fourth quarter of 2017. On February 22, 2018, SCE declared a dividend to Edison International of $212 million that will be paid in the second quarter of 2018.
The CPUC regulates SCE's capital structure which limits the dividends it may pay Edison International.to its shareholders. Under SCE's interpretation of CPUC regulations, SCE may make distributions to Edison International as long as the common equity component of SCE's capital structure remainsmust remain at or above 48% on a 13-month weighted average basis or otherwise satisfiesover the 37-month period that SCE's capital structure is in effect for ratemaking purposes.
Under SCE's interpretation of the CPUC's capital structure decisions, SCE is required to file an application for a waiver of the 48% equity ratio condition discussed above if an adverse financial event reduces its spot equity ratio below 47%. On February 28, 2019, SCE submitted an application to the CPUC requirements. Iffor waiver of compliance with this equity ratio
requirement, describing that while the Revised San Onofre Settlement Agreementcharge accrued in connection with the 2017/2018 Wildfire/Mudslide Events caused its equity ratio to fall below 47% on a spot basis as of December 31, 2018, SCE remains in compliance with the 48% equity ratio over the applicable 37-month average basis. In its application, SCE requested a limited waiver to exclude wildfire-related charges and wildfire-related debt issuances from its equity ratio calculations until a determination regarding cost recovery is approved bymade. Under the CPUC,CPUC's rules, SCE may exclude the $448 million after-tax charge


resulting from the implementationwill not be deemed to be in violation of the Revised San Onofre Settlement Agreement from its ratemaking capital structure (seeequity ratio requirement, and therefore may continue to issue debt and dividends, while the waiver application is pending resolution. For further information, see "Notes to Consolidated Financial Statements—Note 12. CommitmentCommitments and Contingencies" for further information on the Revised San Onofre Settlement Agreement).Contingencies—Contingencies—Southern California Wildfires and Mudslides." At March 31, 2018,2019, without excluding the $448 million$1.8 billion after-tax wildfire related charge incurred in 2018, SCE's 13-month37-month average common equity component of total capitalization was 49.7%49.3% and the maximum additional dividend that SCE could pay to Edison International under this limitation was approximately $446$356 million, resulting in a restriction on net assets of approximately $14.3$13.5 billion. If the Revised San Onofre Settlement Agreementwaiver had been approved by the CPUC at March 31, 2018,


2019, SCE's 37-month average common equity component of total capitalization would have been 49.7%. In its 2020 cost of capital application filed in April 2019, SCE seeks to modify its current capital structure to increase the common equity component of SCE'sits capital structure would have been 50.0% on a 13-month average basis.from its current authorized level of 48% to 52% in 2020. For further details, see "—Regulatory Proceedings—2020 Cost of Capital Application" above.
As a California corporation, SCE's ability to pay dividends is also governed by its obligations under 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.
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, and its ability to access the capital markets, and generate operating cash flows and earnings. If SCE incurs significant costs related to the December 2017 Wildfires or the Montecito Mudslides2017/2018 Wildfire/Mudslide Events and is unable to recover such costs through insurance or from customers or 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 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 March 31, 2018,2019 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 procurement contracts contain provisions that require SCE to maintain an investment grade credit rating from the major credit rating agencies. If SCE's credit rating were to fallratings falling below investment grade, SCE may be required to pay the liability or post additional collateral.grade.

Edison International Parent and Other
In the next 12 months, Edison International expects to fund its net cash requirements through operating cash flows, tax benefitscapital market and bank financings, including by issuing additional debt and capital market financings,equity, as needed.
In April 2019, Edison International registered additional shares of its common stock with the SEC. Edison International anticipates issuing up to $1.5 billion of registered shares of common stock, including through designated broker-dealers at prevailing market prices (an at-the-market offering), and anticipates using the proceeds for equity contributions to SCE and for general corporate and working capital purposes. Also, in April 2019, Edison International entered into a $1.0 billion term loan. Of the proceeds of the term loan, $750 million was contributed to SCE and the remainder of the proceeds will be used for general corporate and working capital purposes. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements." Edison International believes that these contributions will enable SCE to increase the


common equity component of its capital structure to 52% in 2020 as proposed in SCE's Cost of Capital application filed with the CPUC in April 2019.
Edison International also has availability under its credit facility. At March 31, 2019, Edison International Parent had approximately $1.3 billion available under its $1.5 billion credit facility. The credit facility is available for borrowing needs until May 2023 and contains two 1-year extension options. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."
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 access to the bank and capital markets. In addition to having sufficient liquidity, Edison International's ability to pay dividends is dependent upon meetingmeet 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—Dividend Restrictions.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 may also finance common stock dividends, working capital


requirements, payment of obligations, and capital investments, including capital contributions to subsidiaries, and any common stock dividends with short-term or other financings, subject to availability in the bank and capital markets.
As a result of the expected sale of SoCore Energy, Edison Energy Group made several distributions to Edison International Parent including dividend payments of $55 million in the first quarter of 2018 and dividend payments of $46 million in April 2018. For further information, see "Notes to Consolidated Financial Statements—Note 10. Investments."
At March 31, 2018, Edison International Parent had approximately $58 million of cash and cash equivalents and $1.25 billion available of net borrowing capacity under its $1.25 billion multi-year revolving credit facility. The credit facility is available for borrowing needs until July 2022. In January 2018, Edison International Parent issued a $500 million term loan. In March 2018, Edison International Parent issued $550 million of 4.125% senior notes. The proceeds from the March 2018 issuance were used to repay the $500 million term loan discussed above and for general corporate purposes. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements."
A debt covenant in Edison International Parent's credit facility requires a consolidated debt to total capitalization ratio as defined in the credit agreement of less than or equal to 0.650.70 to 1. At March 31, 2018,2019, Edison International Parent's consolidated debt to total capitalization ratio was 0.500.57 to 1.
At March 31, 2018,2019, Edison International Parent was also in compliance with all other 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 rating agencies in March 2019. The following table summarizes Edison International Parent's current long-term issuer credit ratings and outlook from the major credit rating agencies:

Credit RatingBaa3BBB-BBB
OutlookNegativeWatch NegativeWatch Negative
Edison International Parent's credit ratings may be further affected by the ultimate outcome of pending enforcement and litigation matters, including the outcome of the uncertainties and potential liabilities associated with the 2017/2018 Wildfire/Mudslide Events, and the reform of policies allocating liability to investor-owned utilities for damages caused by catastrophic wildfires substantially caused by utility equipment. 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.

Cash flow for the three months ended March 31, 2017 was updated to reflect the implementation of the accounting standards updates for cash flows related to cash receipts and restricted cash.


Net cash provided by operating activities was impacted by the following:
Net income and non-cash items decreased in 20182019 by $64$88 million primarily due to the impact of the July 2017 cost of capital decision on GRC revenue, higher operation and maintenancewildfire mitigation expenses and higher net financing costs. During the first three months ofcosts, partially offset by a 2018 the amounts billedrefund to customers was based on the 2017 authorized GRC revenue requirement and therefore, a regulatory liability (see below) has been established to record any associated adjustments.for prior overcollections.
Net cash for working capital was $(354)$(271) million and $(165)$(354) million during the three months ended March 31, 2019 and 2018, and 2017, respectively. Net cash for working capital in 2019 was primarily impacted by insurance premium payments of $413 million for wildfire-related coverage. The net cash for each period was primarily related to the reductions of payables (including payments for payroll-related costs and purchased power) of $235 million and $230 million during the first quarters of 2018 and 2017, respectively, andalso impacted by changes in receivables from customers of $32 million and $(222) million in 2019 and 2018, and $133 million in 2017.respectively.
Net cash provided by regulatory assets and liabilities, including changes in over (under) collectionsovercollections of balancing accounts was $405$(96) million and $129$405 million during the three months ended March 31, 20182019 and 2017,2018, 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:
2019
BRRBA overcollections decreased by $346 million primarily due to a $163 million reclassification from the pole loading balancing account to BRRBA to recover 2017 undercollections, authorization to recover $107 million of premiums related to a wildfire insurance policy purchased in 2017, lower sales than forecasted in rates and a refund of prior TAMA overcollections.
Net undercollections for ERRA and the new system generation program were $831 million and $741 million at March 31, 2019 and December 31, 2018, respectively. Net undercollections increased $90 million primarily due to higher than forecasted power and gas prices experienced in 2019, partially offset by an increase in cash due to recovery of prior ERRA undercollections.
Net overcollections for TAMA and pole loading balancing account were $128 million at March 31, 2019 compared to net undercollections of $28 million at December 31, 2018. Net overcollections increased by $156 million primarily due to a $163 million reclassification from the pole loading balancing account to BRRBA as discussed above.
Higher cash due to $104 million of overcollections for the public purpose and energy efficiency programs resulting from lower program spending.
Higher cash from increased regulatory liabilities of approximately $90 million primarily due to the delay in the 2018 GRC decision. Amounts billed to customers during first three months of 2019 were based on the 2017 authorized GRC revenue requirement, however, the amount of revenue recognized has been adjusted mainly for the July 2017 cost of capital decision and Tax Reform pending the outcome of the 2018 GRC and therefore, a regulatory liability has been established to record any associated adjustments.


2018
Higher cash due to $143 million of overcollections for the public purpose and energy efficiency programs resulting from lower program spending.
BRRBA overcollections increased by $122 million during the first three months of 2018 primarily due to the timing of revenue, partially offset by thea refund of 2016 TAMA overcollections.incremental tax benefits.
Higher cash of $42 million due to cash collected for San Onofre under the Prior San Onofre Settlement Agreement. For further information, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Permanent Retirement of San Onofre."
Higher cash reflected in regulatory liabilities of approximately $90 million primarily due to the delay in the 2018 GRC decision. Until a final 2018 GRC decision is issued, SCE recognized revenue for the first quarter of 2018 largely based on the 2017 authorized revenue requirement (see discussion above).
2017
Higher cash due to $64 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.
Higher cash due to realization of $47 million in proceeds from the MHI arbitration. For further information on the MHI claims, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Permanent Retirement of San Onofre."
BRRBA overcollections decreased by $66 million during the first three months of 2017 primarily due to the refund of 2015 overcollections resulting from the implementation of the 2015 GRC decision, which was authorized to be refunded to customers over a two-year period.
Higher cash of approximately $84 million primarily due to lower spending for the new system generation program, which records the benefits and costs of power purchase agreements and SCE-owned peaker generation units associated with new generation resources.
Cash flows used in other noncurrent assets and liabilities were primarily related to net earnings from nuclear decommissioning trust investments ($3027 million and $27$30 million in 20182019 and 2017,2018, respectively) and SCE's payments of decommissioning costs ($4173 million and $45$41 million in 20182019 and 2017,2018, respectively). See "Nuclear Decommissioning Activities" below for further discussion.

SCE has contingencies related to San Onofre Related Matters, Nuclear Insurance, December 2017 Wildfires,the 2017/2018 Wildfire/Mudslide Events, wildfire insurance, Montecito Mudslides, Environmental Remediation, Nuclear Insurance and Spent Nuclear Fuel, which are discussed in "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies."
MARKET RISK EXPOSURES
Edison International's and SCE's primary market risks are described in the 20172018 Form 10-K. For a further discussion of market risk exposures, including commodity price risk, credit risk, and interest rate risk, see "Notes to Consolidated Financial Statements—Note 4. Fair Value Measurements" and "—Note 6. Derivative Instruments."
Commodity Price Risk
SCE records derivative instruments on its consolidated balance sheets as either assets or liabilities measured at fair value unless otherwise exempted from derivative treatment as normal purchases or sales. The fair value of outstanding derivative instruments used to mitigate exposure to commodity price risk was reflected as a net asset of $94$110 million and $109$167 million on SCE's consolidated balance sheets at March 31, 20182019 and December 31, 2017,2018, respectively. 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 March 31, 2018, theThe amount of balance sheet exposure as described above broken down by the credit ratings of SCE's counterparties, was as follows:

SCE assigns a credit rating based on the lower of a counterparty's S&P or Moody's rating. For ease of reference, the above table uses the S&P classifications to summarize risk, but reflects the lower of the credit ratings from S&P or Moody's.
2 
Exposure excludes amounts related to contracts classified as normal purchases and sales and non-derivative contractual commitments that are not recorded on the consolidated balance sheets, except for any related net accounts receivable.
3
Exposure to companies with S&P Credit Rating below A is immaterial.
CRITICAL ACCOUNTING ESTIMATES AND POLICIES
For a complete discussion on Edison International's and SCE's critical accounting policies, see "Critical Accounting Estimates and Policies" in the year-ended 20172018 MD&A.
NEW ACCOUNTING GUIDANCE
New accounting guidance is discussed in "Notes to Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies—New Accounting Guidance."

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1.    Summary of Significant Accounting Policies
Organization and Basis of Presentation
Edison International is the parent holding company of Southern California Edison Company ("SCE") and Edison Energy Group, Inc. ("Edison Energy Group"). SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity to an approximately 50,000 square mile area of southern California. Edison Energy Group is a holding company for subsidiaries, including Edison Energy, LLC ("Edison Energy"), which is engaged in pursuingthe competitive business opportunities acrossof providing energy services and managed portfolio solutions forto commercial and industrial customers. SuchEdison Energy's business activities are currently not material to report as a separate business segment. These combined notes to the consolidated financial statements apply to both Edison International and SCE unless otherwise described. Edison International's consolidated financial statements include the accounts of Edison International, SCE, and other wholly owned and controlled subsidiaries. References to Edison International refer to the consolidated group of Edison International and its subsidiaries. References to Edison"Edison International Parent and OtherOther" refer to Edison International Parent and its competitive subsidiaries and "Edison International Parent" refer to Edison International on a stand-alone basis, not consolidated with its subsidiaries. SCE's consolidated financial statements include the accounts of SCE and its wholly owned and controlled subsidiaries. All intercompany transactions have been eliminated from the consolidated financial statements.
Edison International's and SCE's significant accounting policies were described in Note 1 ofthe "Notes to Consolidated Financial Statements" included in Edison International's and SCE's combined Annual Report on Form 10-K for the year-endedyear ended December 31, 20172018 (the "2017"2018 Form 10-K"). This quarterly report should be read in conjunction with the financial statements and notes included in the 20172018 Form 10-K.
In the opinion of management, all adjustments, consisting of recurring accruals, have been made that are necessary to fairly state the consolidated financial position, results of operations, and cash flows in accordance with accounting principles generally accepted in the United States ("GAAP") for the periods covered by this quarterly report on Form 10-Q. The results of operations for the three-month period ended March 31, 20182019 are not necessarily indicative of the operating results for the full year.
The December 31, 20172018 financial statement data was derived from audited financial statements, but does not include all disclosures required by GAAP.
Effective January 1, 2018, Edison International and SCE adopted several accounting standards retrospectively. Prior year financial statements have been updated to reflect the retrospective application of these standards as applicable. For further information, see "New Accounting Guidance" below.
Sale of SoCore Energy
On February 28, 2018, Edison International agreed to sell SoCore Energy LLC ("SoCore Energy"), a then subsidiary of Edison Energy Group, to a third party, subject to the completion of closing conditions, which were satisfied on April 16, 2018. As a result, Edison International accounted for the assets and liabilities of SoCore Energy as held for sale as of March 31, 2018 on the consolidated Edison International balance sheet. See Note 10 for further information.
Cash, Cash Equivalents and Restricted Cash
Cash equivalents includesinclude investments in money market funds. Generally, the carrying value of cash equivalents equals the fair value, as these investments have original maturities of three months or less. The cash equivalents were as follows:

Edison International's restricted cash at March 31, 2018 and December 31, 2017 was $27 million and $41 million, respectively. Restricted cash primarily relates to funds held by SoCore Energy and its consolidated affiliates pursuant to project financing or purchase agreements, most of which are expected to lapse during 2018. As discussed above, Edison International accounted for the assets and liabilities of SoCore Energy as held for sale as of March 31, 2018 (see Note 10 for further information).

Revenue Recognition
DuringRegulatory Proceedings
2018 General Rate Case
In February 2018, SCE updated its 2018 General Rate Case ("GRC") application for the first three monthsimpact of Tax Cuts and Jobs Act ("Tax Reform") resulting in a requested 2018 pendingbase rate revenue requirement of $5.534 billion, a decrease of $106 million over the outcome2017 GRC authorized revenue requirement.
In April 2019, the CPUC issued a 2018 GRC proposed decision, which if adopted, would result in a base rate revenue requirement of $5.102 billion in 2018, a decrease of $432 million from SCE's requested revenue requirement, primarily related to a reduction in authorized rate base, depreciation and operation and maintenance expenses. The proposed decision also identifies changes to certain balancing accounts, including the expansion of the TAMA to include the impacts of all differences between forecast and recorded tax expense. The proposed decision would also disallow certain historical spending, largely related to certain infrastructure replacement programs and corporate real estate.
The CPUC did not issue a decision on the 2018 GRC decision,application during 2018 or during the first quarter of 2019, therefore SCE recognized GRC-related revenue based on the 2017 authorized revenue requirement, adjusted for items SCE has determined to be probable of occurring, primarily the July 2017 cost of capital decision and the impact of Tax Reform. The amounts billed to customers for the first three months of 2018 was also based on the 2017 authorized revenue requirement and a regulatory liability has been established to record any associated adjustments. The CPUC has authorizedapproved the establishment of a GRC memorandum account which will makeand the 2018 and 2019 revenue requirementrequirements ultimately adopted by the CPUC will be effective as of January 1, 2018.2018 and January 1, 2019, respectively. See Note 11 for further details. The proposed decision, if adopted as drafted, would have a significant impact on SCE and Edison International’s reported results, including an impairment of utility property, plant and equipment of up to $257 million ($185 million after-tax) related to disallowed historical capital expenditures and an increase to earnings of approximately $130 million from application of the decision to revenue, depreciation and income tax expense retroactively for 2018 and the first quarter of 2019.
The proposed decision would allow a post-test year rate making mechanism that escalates capital additions by 2.49% for both 2019 and 2020. It would also allow operation and maintenance expenses to be escalated for 2019 and 2020 through the use of various escalation factors for labor, non-labor and medical expenses. The methodology set forth in the proposed decision would, if adopted by the CPUC, result in a revenue requirement of $5.422 billion in 2019 and $5.823 billion in 2020.
SCE will file comments on the proposed decision in May 2019 and SCE cannot predict the revenue requirement the CPUC will authorize or provide assurance on the timing ofwhen a final decision will be issued. A final decision could result in material changes to the proposed decision.
FERC Formula Rate
In October 2017, SCE filed its new formula rate with the FERC. In December 2017, the FERC issued an order setting the effective date of SCE's new FERC formula rate as of January 1, 2018, subject to settlement procedures and refund. In November 2018, SCE filed its 2019 annual update with the FERC with the proposed rates effective January 1, 2019, subject to settlement procedures and refund, and requested a decrease in transmission revenue requirement of $131 million, or 11% from amounts currently authorized in rates. Pending resolution of the FERC formula rate proceeding,proceedings, SCE is recognizing recognized


revenue in 2018 and during the first quarter of 2019 based on the FERC formula rate adjusted for the impact of Tax Reform and other adjustments.

In April 2019, SCE filed an application with FERC to amend the formula rate associated with its transmission facilities in 2019. In the revised formula rate, SCE seeks a base return on equity of 17.12% ("FERC Base ROE"), compared to its proposed base ROE of 10.30% for its 2018 formula rate. The requested FERC Base ROE reflects a conventional ROE of 11.12% and an additional ROE of 6% to compensate investors for current wildfire risk. SCE would seek to reduce or remove the additional wildfire risk ROE if there is a material reduction in its wildfire cost recovery risk due to regulatory or legislative reform. SCE's total ROE request, inclusive of project incentives and a 0.5% incentive for CAISO participation, is approximately 18.4%.

If the new formula rate is accepted by FERC, it will supersede the existing formula rate, including the 2019 annual update, and could become effective as early as 60 days from the filing date. FERC has the authority to, and may, suspend new rates for up to five months. If the new formula rate is suspended by FERC, the 2019 transmission revenue requirement rate established in the 2019 annual update will continue to be effective, subject to refund, from January 1, 2019 until the end of the suspension of the new formula rate. The new formula rate would likely be subject to refund from the end of the suspension until it is ultimately approved by FERC.
If the revised formula rate becomes effective on June 12, 2019 (the effective date requested by SCE), SCE's proposed revisions to its formula rate will result in a projected increase in its retail base transmission revenue requirement in 2019 of approximately $290 million from the currently effective retail base transmission revenue requirement of approximately $1 billion.
See Note 7 for further information on SCE's revenue.
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 restricted stock units, which earn dividend equivalents on an equal basis with common shares once the awards are vested. EPS attributable to Edison International common shareholders was computed as follows:

In addition to the participating securities discussed above, Edison International also may award stock options, which are payable in common shares and are included in the diluted earnings per share calculation. Stock option awards to purchase 6,222,2947,719,306 and 1,355,9306,222,294 shares of common stock for the three months ended March 31, 20182019 and 2017,2018, respectively, were outstanding, but were not included in the computation of diluted earnings per share because the effect would have been antidilutive.
New Accounting Guidance
Accounting Guidance Adopted
In May 2014, the Financial Accounting Standards Board ("FASB") issued an accounting standards update on revenue recognition and further amended the standard in 2016 and 2017. Under the new standard, revenue is recognized when a good or service is transferred to the customer and the customer obtains control of the good or service. Some revenue arrangements, such as alternative revenue programs which include balancing account overcollections and undercollections, are excluded from the scope of the new standard and, therefore, will be accounted for and presented separately from revenue recognized from contracts with customers in the disclosures.On January 1, 2019, Edison International and SCE adopted this standard effective January 1, 2018, using the modified retrospective method for contracts that were not completed as of the adoption date. Edison International recognized a cumulative effect adjustment to increase the opening balance of retained earnings by approximately $5 million ($7 million pre-tax) on January 1, 2018. This adjustment is related to variable consideration recognized at Edison Energy which is not subject to potential significant reversal and has no further performance obligations. See Note 7 for further details.
In January 2016, the FASB issued an accounting standards updateupdates that amends the guidancerequire lessees to recognize a lease on the classificationbalance sheet as a right-of-use ("ROU") asset and measurement of financial instruments,related lease liability and further amendedclassify the guidance in 2018. Under the new guidance, equity investments (excluding those accounted for under the equity methodlease as either operating or those that result in consolidation) are required to be measured at fair value, with changes in fair value recognized in net income. The new guidance also amends certain disclosure requirements associated with the fair value of financial instruments and 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 assets.


finance. Edison International and SCE adopted this guidance effective January 1, 2018. Edison International recognized a cumulative effect adjustmentusing the modified retrospective approach for leases that existed as of the adoption date and elected the optional transition method not to increase the opening balance of retained earnings and accumulated other comprehensive loss by $5 million ($8 million pre-tax) on January 1, 2018. See Note 2 for further details.
The FASB issued two accounting standards updates relatedrestate periods prior to the statement of cash flows. One standard update clarifies the presentation and classification of certain cash receipts and payments in the statement of cash flows and other requires restricted cash to be presented with cash and cash equivalents in the statement of cash flows.adoption date. Edison International and SCE adopted these standards effective January 1, 2018, usingalso elected the retrospective approach. The adoptionpackage of these standards didpractical expedients not have a material impact on Edison International'sto reassess prior conclusions related to contracts containing leases, lease classification and SCE's consolidated statement of cash flows.
In March 2017,initial direct costs, and the FASB issued an accounting standards update on the presentation of the components of net periodic benefit cost for an entity's defined benefit pension and other postretirement plans. Edison International and SCE adopted this guidance effective January 1, 2018. The adoptionpractical expedient not to reassess existing land easements. Adoption of this standard did not have a material impactincreased ROU assets and lease liabilities on Edison International's and SCE'sthe consolidated financial statements, but did result in the separate presentation of service costs as an operating expense and non-service costs within other income and expenses and limits the capitalization of benefit costs to the service cost component. The standard was adopted retrospectively with respect to the income statement presentation requirement and prospectively for the capitalization requirement. During the three months ended March 31, 2017, non-service costs (benefits) totaled $(8)balance sheets by $956 million and $(9)$951 million as of January 1, 2019 for Edison International and SCE, respectively, which were reclassified from "Operation and maintenance" to "Otherrespectively. The standard did not materiality impact the consolidated statements of income and expenses." See Note 9 and Note 14 for further details.Edison International or SCE.
Accounting Guidance Not Yet Adopted
In February 2016, the FASB issued anBased on accounting standards update related to lease accounting and further amended the standard in 2018. The updated standard is effectiveadopted at January 1, 2019. Under the new standard,2019, 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 needThis occurs when an entity has the right to recognize leases onobtain substantially all of the balance sheeteconomic benefits from and has the right to direct the use of the identified asset. SCE determines if an arrangement is a lease at contract inception, and for all classes of assets, SCE includes both lease and non-lease components as a right-of-use assetsingle component and accounts for it as a related lease liability, and classify the leases as either operating or finance. The liability will be equal tolease. Lease liabilities are recognized based on the present value of the lease payments. The asset will bepayments over the lease term at the commencement date. Lease ROU assets are based on the liability, subject to adjustments, such as initial direct costs. Edison International'slease incentives. In measuring lease assets and liabilities, SCE excludes variable lease payments, other than those that depend on an index, a rate or are in substance fixed payments and includes lease payments made at or before the commencement date. SCE's lease terms include options to extend or terminate the lease when it is reasonably certain that such options will be exercised. Operating leases are included in operating lease ROU assets and operating lease liabilities on the consolidated balance sheets. Finance leases will resultare included in straight-line expenseproperty, plant and equipment and other liabilities on the consolidated balance sheets. See Note 13 for further information.
In February 2018, the FASB issued an accounting standards update to provide entities an election to reclassify stranded tax effects resulting from Tax Reform from accumulated other comprehensive income to retained earnings. Stranded tax effects originated in December 2017 when deferred taxes were re-measured at the lower federal corporate tax rate with the impact included in operating income, 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 recognize expense using the timing that conforms to the regulatory rate treatment. Lessees can elect to exclude from the balance sheet short-term contractstax effects of one year or less. This standard requires retrospective application to previously issued financial statements for 2018 and 2017. Although permitted,items within accumulated other comprehensive income were not similarly adjusted. Edison International and SCE has elected notadopted this guidance on January 1, 2019 and reclassified stranded tax effects of $10 million and $5 million, respectively, from accumulated other comprehensive income to adoptretained earnings. See Notes 2 and 14 for further information.
In August 2018, the FASB issued an accounting standards update to remove, modify, and add certain disclosure requirements related to fair value measurement. Edison International and SCE adopted this standard prior toguidance effective January 1, 2019.

The adoption 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 implementing a new lease accounting system and are evaluating the impact this standard will have on the consolidated balance sheets and lease disclosures. See Note 4 for further information.
Accounting Guidance Not Yet Adopted
The FASB issued an accounting standards update in June 2016, and further amended the guidance in November 2018, 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.losses over the remaining life of most financial assets measured at amortized cost, including trade and other receivables. The guidance also requires use of an allowance to record estimated credit losses on available-for-sale debt securities. Edison International and SCE are currently evaluating the impact of this new guidance.guidance and do not expect the adoption of the guidance will have material impact on Edison International and SCE.
In January 2017, the FASB issued an accounting standards update to simplify the accounting for goodwill impairment. This accounting standards update changesimpairment by changing the procedural steps in applyingto apply the goodwill impairment test. AAfter the adoption of this accounting standards update, goodwill impairment will now be measured as 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 testtests beginning in 2020.


In FebruaryAugust 2018, the FASB issued an accounting standards update related to stranded income tax effects due towhich aligns the 2017 Tax Reform enacted on December 22, 2017.

In August 2018, the FASB issued an accounting standards update to remove, modify, and add certain disclosure requirements related to employer-sponsored defined benefit pension or other postretirement plans. The guidance is effective January 1, 2021, with early adoption permitted. Edison International and SCE are currently evaluating the impact of the guidance and do not expect the adoption of this standard will materially affect disclosures.

Note 3.    Variable Interest Entities
A VIEvariable interest entity ("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 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 site and equipment selection, construction, operation and maintenance, fuel procurement, dispatch, and compliance with regulatory and contractual requirements.


Variable Interest in VIEs that are not Consolidated
Power Purchase Agreements
SCE has power purchase agreements ("PPAs") that are classified as variable interests in VIEs, including tolling agreements through which SCE provides the natural gas to fuel the plants, and contracts with qualifying facilities that contain variable pricing provisions based on the price of natural gas.gas and renewable energy contracts through which SCE absorbs commodity price risk. 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 result from current amounts due under the PPAs. Under these contracts, SCE recovers the costs incurred through demonstration of compliance with its California Public Utilities Commission ("CPUC")-approved long-term power procurement plans. SCE has no residual interest in the entities and has not provided or guaranteed any debt or equity support, liquidity arrangements, performance guarantees, or other commitments associated with these contracts other than the purchase commitments described in Note 11 of the 20172018 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 3,4544,722 MW and 4,9283,454 MW at March 31, 20182019 and 2017,2018, respectively, and the amounts that SCE paid to these projects were $143$153 million and $140$143 million for the three months ended March 31, 20182019 and 2017,2018, respectively. These amounts are recoverable in customer rates, subject to reasonableness review.


Unconsolidated Trusts of SCE
SCE Trust II, Trust III, Trust IV, Trust V, and Trust VI were formed in 2013, 2014, 2015, 2016, and 2017, respectively, for the exclusive purpose of issuing the 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 II, Trust III, Trust IV, Trust V and Trust VI issued to the public trust securities in the face amounts of $400 million, $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 G, Series H, Series J, Series K, and Series L Preference Stock issued by SCE in the principal amounts of $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 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 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 boardBoard of directorsDirectors 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.
SCE formed Trust I, a VIE, in 2012 for the exclusive purpose of issuing 5.625% trust preference securities. SCE Trust I issued trust securities in the face amounts of $475 million to the public and $10,000 of common stock to SCE. SCE Trust I invested the proceeds of these trust securities in Series F Preference Stock issued by SCE in the principal amount of $475 million. In July 2017, all of the outstanding Series F Preference Stock was redeemed, and accordingly, 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 VI balance sheets as of March 31, 20182019 and December 31, 2017,2018, consisted of investments of $400 million, $275 million, $325 million, $300 million, and $475 million in the Series G, Series H, Series J, Series K and Series L Preference Stock, respectively, $400 million, $275 million, $325 million, $300 million, and $475 million of trust securities, respectively, and $10,000 each 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 March 31, 20182019 and December 31, 2017,2018, 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 thean 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.

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 2018 and 2017.
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.
The following table sets forth SCE's valuation techniques and significant unobservable inputs used to determine fair value for significant Level 3 assets and liabilities:

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.

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 plant and peaker plants, QF 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.
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, 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 $1 million and $4 million as of both March 31, 20182019 and December 31, 2017,2018, respectively, for which SCE has posted less than $1no collateral and $17 million collateral at both March 31, 20182019 and December 31, 2017,2018, respectively, to its counterparties for its derivative liabilities and related outstanding payables. If the credit-risk-related contingent features underlying these agreements were triggered on March 31, 2018,2019, SCE would be required to post $12$1 million of additional collateral of which $11 million is related to outstanding payables that are net of collateral already posted.collateral.


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:

Income Statement Impact of Derivative Instruments
SCE recognizes realized gains and losses on derivative instruments as purchased power expense and expects that such gains or losses will be part of the 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 reported in cash flows from operating activities in the consolidated statements of cash flows.

Note 7.    Revenue
Revenue is recognized by Edison International and SCE when a performance obligation to transfer control of the promised goods is satisfied or when services are rendered to our customers. This typically occurs when electricity is delivered to our customers, which includes amounts for services rendered but unbilled at the end of a reporting period.
Edison International Parent and Other revenue primarily relates to Edison Energy Group, a holding company for subsidiaries engaged in pursuing competitive business opportunities across energy services and managed portfolio solutions to commercial and industrial customers. The revenue for Edison International Parent and Other is immaterial to Edison International.
CPUC and FERC rates decouple authorized revenue from the volume of electricity sales and the price of energy procured so that SCE receives revenue equal to amounts authorized by the relevant regulatory agencies. As a result, the volume of electricity sold to customers and specific customer classes does not have a direct impact on SCE's financial results. 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 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 revenuesrevenue 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. 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), and certain operation and maintenance expenses. SCE earns no return on these activities.

SCE's Revenue from Contracts with Customers
Provision of Electricity
SCE principally generates revenue from contracts with customers through supplying and delivering electricity to its customers. Rates charged to customers are based on tariff rates, approved by the CPUC and FERC. Revenue is authorized by the CPUC through triennial GRC proceedings which are intended to provide SCE a reasonable opportunity to recover its costs and earn a return on its CPUC-jurisdictional rate base. The CPUC sets an annual revenue requirement for the base year


and the remaining two years are set by a methodology established in the GRC proceeding. Differences between the amount collected and authorized levels are either collected from or refunded to customers, and therefore, such differences do not impact operating revenue (see alternative revenue programs below for further information). In addition to the utility earnings activity revenue described above, SCE also earns revenue to recover costs for power procurement and other activities. SCE earns no return on these activities.
Revenue is authorized by the FERC through a formula rate which is intended to provide SCE a reasonable opportunity to recover transmission capital and operating costs that are prudently incurred, including a return on its FERC-jurisdictional rate base. Under the operation of the formula rate, transmission revenue is updated to actual cost of service annually.
For SCE's electricity sales for non-residential customers, SCE satisfies the performance obligation of delivering electricity over time as the customers simultaneously receive and consume the delivered electricity. Since SCE has a right to invoice an amount that corresponds to the value of the delivered electricity mandated in the tariff rates established by the CPUC and FERC, SCE is eligible for and has elected the right-to-invoice practical expedient which allows SCE to recognize revenue for tariff sales in the amount for which SCE has a right to invoice. This is consistent with how SCE recognized revenue for tariff sales prior to the adoption of the new standard.
Energy sales for residential customers are typically on a month to month implied contract for transmission, distribution and generation services, while commercial and other non-residential customer contracts can extend up to 20 years. Revenue is recognized over time as the energy is supplied and delivered to its customers and the respective revenue is billed and paid on a monthly basis.
Sales and Use Taxes
SCE bills certain sales and use taxes levied by state or local governments to its customers. Included in these sales and use taxes are franchise fees, which SCE pays to various municipalities (based on contracts with these municipalities) in order to operate within the limits of the municipality. SCE bills these franchise fees to its customers based on a CPUC-authorized rate. These franchise fees, which are required to be paid regardless of SCE's ability to collect from the customer, are accounted for on a gross basis. Revenue is reflected in "Revenue from contracts with customers" in 2018 (see table above) and in "Operating revenue" in 2017 and expenses are reflected in "Operation and maintenance." SCE's franchise fees billed to customers were $28 million and $29 million for the three months ended March 31, 2018 and 2017, respectively. When SCE acts as an agent for sales and use tax, the taxes are accounted for on a net basis. Amounts billed to and collected from customers for these taxes are remitted to the taxing authorities and are not recognized as electric utility revenue.
Provision of Electrical Transmissions Services and Other Revenue from Contracts with Customers
SCE also provides services to non-residential customers that include the use of SCE's owned transmission lines to transmit electricity from generation facilities to the grid and provide the use of SCE-owned facilities to connect to the grid. SCE contracts with its customers through contracts that are on a month to month basis. The contract pricing for the use of SCE's transmission lines is mandated by tariff rates approved by either the CPUC or FERC, as applicable. Revenue is recognized over time as the services are provided. The revenue is billed and paid monthly.
SCE also earns an immaterial amount of revenue through telecommunication services and the sale of excess energy to customers.
The estimated revenue expected to be recognized in the future related to SCE's performance obligations that are not completed (or partially completed) at March 31, 2018 is immaterial.
SCE's Alternative Revenue Programs
Alternative Revenue Programs Decoupling
Rates charged to customers are based on CPUC- and FERC- authorized revenue requirements as discussed above. CPUC and FERC rates decouple authorized revenue from the volume of electricity sales. Differences between amounts collected and authorized levels are either collected from or refunded to customers, and therefore, SCE earns revenue equal to amounts authorized.
The differences between amounts billed and authorized levels for both CPUC and FERC are reflected in "Alternative revenue programs and other operating revenue" in 2018 (see table above) and in "Operating revenue" in 2017.


Other Alternative Revenue Programs
The CPUC and FERC have authorized additional, alternative revenue programs which adjust billings for the effects of broad external factors or to compensate SCE for demand-side management initiatives and provide for incentive awards if SCE achieves certain objectives. These alternative revenue programs have been authorized to allow SCE to recover costs that SCE has been authorized to pass on to customers, including costs to purchase electricity and natural gas; and to fund public purpose, demand response, and customer energy efficiency programs. In general, revenue is recognized for these alternative revenue programs at the time the costs are incurred and, for incentive-based programs, at the time the awards are approved by the CPUC. SCE begins recognizing revenues for these programs when a program has been established by an order from either the CPUC or FERC that allows for automatic adjustment of future rates, the amount of revenue for the period is objectively determinable and probable of recovery and the revenue will be collected within 24 months following the end of the annual period.

Relates to changes in the allocation of deferred tax re-measurement between customers and shareholders as a result of a CPUC resolution issued in February 2019. The resolution determined that customers are only entitled to excess deferred taxes which were included when setting rates, while other deferred tax re-measurement belongs to the shareholders.
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.

During the first quarter of 2018, Edison International and SCE adopted an accounting standard retrospectively related to the presentation of the components of net periodic benefit costs for the defined benefit pension and other postretirement plans. Prior years' consolidated income statements have been updated to reflect the retrospective application of this accounting standard. Service and non-service costs are included in "Operation and maintenance" and "Other income and expenses," respectively, on the consolidated income statement. See Note 1 for further information.
Postretirement Benefits Other Than Pensions ("PBOP(s)"PBOP")
Edison International made contributions of $3 million during the three months ended March 31, 2018 and expects to make contributions of $9 million during the remainder of 2018, 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 in retirement depends on a number of factors, including the employee's years of service, age, hire date, and retirement date. Under the terms of the Edison International Health and Welfare Benefit Plan ("PBOP Plan") 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.

Note 12.    Commitments and Contingencies
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. 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 indemnifiedagreed to indemnify 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. As of March 31, 2019, there has been no groundwater contamination identified. Thus, 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 these other proceedings will not, individually or in the aggregate, materially affect its financial position, results of operations and cash flows.


Southern California Wildfires and Mudslides
Approximately 35% of SCE's service territory is in areas identified as high fire risk by SCE. Multiple factors have contributed to increased wildfires, faster progression of wildfires and the increased damage from wildfires across SCE's service territory and throughout California. These include the buildup of dry vegetation in areas severely impacted by years of historic drought, lack of adequate clearing of hazardous fuels by responsible parties, higher temperatures, lower humidity, and strong Santa Ana winds. At the same time that wildfire risk has been increasing in Southern California, residential and commercial development has occurred and is occurring in some of the highest-risk areas. Such factors can increase the likelihood and extent of wildfires.
In December 2017 severaland November 2018, wind-driven wildfires (the "December 2017 Wildfires") impacted portions of SCE's service territory, and causedcausing 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 thesethe 2017 fires knownoriginated on December 4, 2017, in the Anlauf Canyon area of Ventura County (the investigating agencies refer to this fire as the Thomas Fire,"Thomas Fire"), followed shortly thereafter by a second fire that originated near Koenigstein Road in Ventura County andthe City of Santa Paula (the "Koenigstein Fire"). While the progression of these two fires remains under review, the December 4, 2017 fires eventually burned substantial acreage located in both Ventura and Santa Barbara Counties. According to the most recent California Department of Forestry and Fire Protection ("Cal Fire") incidentCAL FIRE information, reports, the Thomas Fireand Koenigstein Fires burned over 280,000 acres, destroyed or damaged an estimated 1,0631,343 structures and resulted in two fatalities. The largest of the November 2018 fires, known as the Woolsey Fire, originated in Ventura County and burned acreage in both Ventura and Los Angeles Counties. According to CAL FIRE information, the Woolsey Fire burned almost 100,000 acres, destroyed an estimated 1,643 structures, damaged an estimated 280364 structures and resulted in one fatality. three fatalities.
As of March 31, 2018, SCE had incurred approximately $46 million of capital expendituresdescribed below, multiple lawsuits related to restoration of service resulting from the December 2017 Wildfires.
Determining wildfire originThomas and cause is often a complexKoenigstein Fires and time-consuming process,the Woolsey Fire have been initiated against SCE and several investigations into the facts and circumstancesEdison International. Some of the Thomas Fire are believed to be ongoing.and Koenigstein Fires lawsuits claim that SCE and Edison International have responsibility for the damages caused by mudslides and flooding in Montecito and surrounding areas in January 2018 (the "Montecito Mudslides") based on a theory that SCE has been advisedresponsibility for the Thomas and/or Koenigstein Fires and that the originsThomas and/or Koenigstein Fires proximately caused the Montecito Mudslides. According to Santa Barbara County initial reports, the Montecito Mudslides destroyed an estimated 135 structures, damaged an estimated 324 structures, and causesresulted in 21 fatalities, with two additional fatalities presumed.
The extent of the fire are being investigated by Cal Fire and the Ventura County Fire Department. In connection with its investigation of the Thomas Fire, Cal Fire has removed and retained certain of SCE's equipment that was located near suspected ignition points of the fire. SCE expects that the Ventura County Fire Department and/or Cal Fire will ultimately issue reports concerning the origins and causes of the Thomas Fire but cannot predict when these reports will be released or if any findings will be issued before the investigations are completed. The CPUC's SED is also conducting an investigation to assess the compliance of SCE and its facilities with applicable rules and regulations in areas impacted by the Thomas Fire. In addition, as it does in all wildfire matters in which its facilities may or are alleged to be involved, SCE is conducting its own investigation of the Thomas Fire. At this time, SCE cannot predict when its own investigation, or the investigations of Cal Fire, the Ventura County Fire Department or the SED, will be completed.
Any potential liability for December 2017 Wildfire-relatedwildfire-related damages will dependin actions against utilities depends on a number of factors, including whether SCE substantially caused or contributed to the damages and whether parties seeking recovery of damages will be


required to show negligence in addition to causation. Certain 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 for alleged violations of CPUC rules and state laws in connection with the ignition of a wildfire.
Final determinations of liability for the Thomas Fire, the Koenigstein Fire, the Montecito Mudslides and the Woolsey Fire (each a "2017/2018 Wildfire/Mudslide Event," and, collectively, the "2017/2018 Wildfire/Mudslide Events"), including determinations of whether SCE was negligent, would only be made during lengthy and complex litigation processes. Even when investigations are still pending or liability is disputed, an assessment of likely outcomes, including through future settlement of disputed claims, may require a liability to be accrued under accounting standards. Based on information available to SCE and consideration of the risks associated with litigation, Edison International and SCE expect to incur a material loss in connection with the 2017/2018 Wildfire/Mudslide Events and accrued a liability of $4.7 billion in the fourth quarter of 2018. In the fourth quarter of 2018, Edison International and SCE also recorded expected recoveries from insurance of $2.0 billion and expected recoveries through FERC electric rates of $135 million. The net charge to earnings recorded in the fourth quarter of 2018 was $1.8 billion after-tax. The liability that was accrued corresponds to the lower end of the reasonably estimated range of expected potential losses that may be incurred in connection with the 2017/2018 Wildfire/Mudslide Events and is subject to change as additional information becomes available. Edison International and SCE will seek to offset any actual losses realized with recoveries from insurance policies in place at the time of the events and, to the extent actual losses exceed insurance, through electric rates. The CPUC and FERC may not allow SCE to recover uninsured losses through electric rates if it is determined that such losses were not reasonably or prudently incurred. See "—Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates" for additional information.
External Investigations and Internal Review
The VCFD and CAL FIRE have issued reports concerning their findings regarding the causes of the Thomas Fire and the Koenigstein Fire. The VCFD and CAL FIRE findings do not determine legal causation of or assign legal liability for the Thomas or Koenigstein Fires; final determinations of legal causation and liability would only be made during lengthy and complex litigation. The reports did not address the causes of the Montecito Mudslides. SCE expects that the VCFD and CAL FIRE will ultimately also issue a report concerning the departments' findings of origin and cause of the Woolsey Fire but cannot predict when this report will be released. The CPUC's Safety Enforcement Division ("SED") is also conducting investigations to assess SCE's compliance with applicable rules and regulations in areas impacted by the fires. SCE cannot predict when the SED's investigations will be completed.
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 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 molten metal was found on the ground in that location during their investigation. 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 progression of the Thomas Fire and the extent of damages that may be attributable to that fire.
Koenigstein Fire
On March 20, 2019, the VCFD and CAL FIRE 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 has previously disclosed that SCE believed its equipment was associated with the ignition of the


Koenigstein Fire. SCE is continuing to assess the progression of the Koenigstein Fire and the extent of damages that may be attributable to that 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 maintained debris basins, roads, bridges and other channel crossings, could have proximately caused, contributed to or exacerbated the 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 outageon 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. Whether the November 8, 2018 outage was related to contact being made between the support wire and the electrical wire has not been determined. SCE believes that its equipment could be found to have been 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.
Wildfire-related Litigation
Multiple lawsuits related to the 2017/2018 Wildfire/Mudslide Events naming SCE as a defendant have been filed. A number of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. The lawsuits, which have been filed in the superior courts of Ventura, Santa Barbara and Los Angeles Counties in the case of the Thomas and Koenigstein Fires and the Montecito Mudslides, and in Ventura and Los Angeles Counties in the case of the Woolsey Fire, allege, among other things, negligence, inverse condemnation, trespass, private nuisance, personal injury, wrongful death, and violations of the California Public Utilities and Health and Safety Codes. SCE expects to be the subject of additional lawsuits related to the 2017/2018 Wildfire/Mudslide Events. The litigation could take a number of years to be resolved because of the complexity of the matters and number of plaintiffs.
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. On October 4, 2018, the 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 January 2019, SCE filed a cross-complaint against certain governmental 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.
Additionally, in July 2018 and September 2018, two separate derivative lawsuits for breach of fiduciary duties and unjust enrichment were filed in the Los Angeles Superior Court against certain current and former members of the Boards of Directors of Edison International and SCE. Edison International and SCE are identified as nominal defendants in those actions. The derivative lawsuits generally allege that the individual defendants violated their fiduciary duties by causing or allowing SCE to operate in an unsafe manner in violation of relevant regulations, resulting in substantial liability and damage from the Thomas and Koenigstein Fires and the Montecito Mudslides.
In November 2018, a purported class action lawsuit alleging securities fraud and related claims was filed in the federal court against EIX, SCE and certain current and former officers of Edison International and SCE. The plaintiff alleges that Edison International and SCE made false and/or misleading statements in filings with the Securities and Exchange Commission by failing to disclose that SCE had allegedly failed to maintain its electric transmission and distribution networks in compliance with safety regulations, and that those alleged safety violations led to fires that occurred in 2018, including the Woolsey Fire.


In January 2019, two separate derivative lawsuits alleging breach of fiduciary duties, securities fraud, misleading proxy statements, unjust enrichment, and related claims were filed in federal court against all current and certain former members of the Boards of Directors and certain current and former officers of Edison International and SCE. Edison International and SCE are named as nominal defendants in those actions. The derivative lawsuits generally allege that the individual defendants breached their fiduciary duties and made misleading statements or allowed misleading statements to be made (i) between March 21, 2014 and August 10, 2015, with respect to certain ex parte communications between SCE and CPUC decision-makers concerning the settlement of the San Onofre Order Instituting Investigation proceeding (the "San Onofre OII") and (ii) from February 23, 2016 to the present, concerning compliance with applicable laws and regulations concerning electric system maintenance and operations related to wildfire risks. The lawsuits generally allege that these breaches of duty and misstatements led to substantial liability and damage resulting from the disclosure of SCE's ex parte communications in connection with the San Onofre OII settlement, and from the 2017/2018 Wildfire/Mudslide Events. For more information regarding the San Onofre OII, see Note 12 in the 2018 Form 10-K.
Loss Estimates for Third Party Claims and Potential Recoveries from Insurance and through Electric Rates
The process for estimating losses associated with wildfire litigation claims requires management to exercise significant judgment based on a number of assumptions and subjective factors, including but not limited to estimates based on currently available information and assessments, opinions regarding litigation risk, and prior experience with litigating and settling other wildfire cases. As additional information becomes available, management estimates and assumptions regarding the causes and financial impact of the 2017/2018 Wildfire/Mudslide Events may change. Such additional information is expected to become available from multiple external sources, during the course of litigation, and from SCE's ongoing internal review, including, among other things, information regarding the extent of damages that may be attributable to any fire determined to have been substantially caused by SCE's equipment, information that may be obtained from the equipment in CAL FIRE's possession, and information pertaining to fire progression, suppression activities, alleged damages and insurance claims.
As described above, the $1.8 billion after-tax liability corresponds to the lower end of the reasonably estimated range of expected losses that may be incurred in connection with the 2017/2018 Wildfire/Mudslide Events and is subject to change as additional information becomes available. Edison International and SCE currently believe that it is reasonably possible that the amount of the actual loss will be greater than the amount accrued. However, Edison International and SCE are currently unable to reasonably estimate an upper end of the range of expected losses given the 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, whether inverse condemnation will be held applicable to SCE with respect to damages caused by the Montecito Mudslides, and the preliminary nature of the litigation processes.
For events that occurred in 2017 and early 2018, principally the Thomas and Koenigstein Fires and Montecito Mudslides, SCE has $1 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence. SCE also had other general liability insurance coverage of approximately $450 million, but it is uncertain whether these other policies would apply to liabilities alleged to be related to the Montecito Mudslides. For the Woolsey Fire, SCE has an additional $1 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence. Edison International and SCE record a receivable for insurance recoveries when recovery of a recorded loss is determined to be probable. At March 31, 2019, Edison International and SCE had recorded $2.0 billion for expected insurance recoveries associated with the recorded loss for the 2017/2018 Wildfire/Mudslide Events. SCE will seek to recover uninsured costs resulting from the 2017/2018 Wildfire/Mudslide Events through electric rates. The amount of the receivable is subject to change based on additional information. Recovery of these costs 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 SDG&E's requests for cost recovery related to 2007 wildfire activity, where 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 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 future wildfire cost-recovery proceedings. SCE will continue to evaluate the probability of recovery based on available evidence, including guidance that may be issued by the Commission on Catastrophic Wildfire Cost and Recovery, and new 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. SCE will seek recovery of the CPUC portion of any uninsured wildfire-related costs through its WEMA. See "—Recovery of Wildfire-Related Costs" below.
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 a regulatory asset of $135 million, the FERC portion of the $4.7 billion liability accrued.
At March 31, 2019 and December 31, 2018, the balance sheets include estimated losses (established at the lower end of the reasonably estimated range of expected losses) of $4.7 billion for the 2017/2018 Wildfire/Mudslide Events.
Current Wildfire Insurance Coverage
SCE has approximately $1 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence, for events (including the Woolsey fire) during the period June 30, 2018 through May 31, 2019. If the $1 billion of insurance coverage is exhausted as a result of liabilities related to the Woolsey Fire, SCE has approximately $735 million of wildfire-specific insurance coverage for wildfire events during the period February 1, 2019 through May 31, 2019, subject to a self-insured retention of $35 million per occurrence and up to $15 million of co-insurance, which results in net coverage of approximately $685 million. SCE has also obtained approximately $1.2 billion of wildfire-specific insurance coverage for events that may occur during the period June 1, 2019 through June 30, 2020, subject to up to $115 million of co-insurance and $50 million of self-insured retention, which results in net coverage of approximately $1 billion. SCE expects its coverage for this period to be subject to an initial self-insured retention of $10 million per occurrence, but, based on policies currently in place, SCE's coverage for the period is subject to a self-insurance retention of $50 million per occurrence. SCE may obtain additional wildfire-specific insurance for this time period in the future. Various coverage limitations within the policies that make up SCE's wildfire insurance coverage could result in additional material self-insured costs in the event of multiple wildfire occurrences during a policy period or with a single wildfire with damages in excess of the policy limits.
SCE's cost of obtaining wildfire insurance coverage has increased significantly as a result of, among other things, the number of recent and significant wildfire events throughout California and the application of inverse condemnation to investor-owned utilities. As such, SCE may not be able to obtain sufficient wildfire insurance at a reasonable cost.
Based on policies currently in effect, SCE anticipates that its wildfire insurance expense, prior to any regulatory deferrals, will total approximately $399 million during 2019. Wildfire insurance expense will increase in 2019 if SCE obtains additional wildfire-specific insurance. In February 2019, the CPUC approved recovery of $107 million of the costs incurred by SCE to obtain a 12-month, $300 million wildfire insurance policy in December 2017. As a result of this decision, SCE will recover these insurance premiums during 2019. As of March 31, 2019, SCE had regulatory assets of $148 million related to wildfire insurance costs and believes that such amounts are probable of recovery. While SCE believes that amounts deferred are probable of recovery, there is no assurance that SCE will be allowed to recover costs that have been incurred, or costs incurred in the future for additional wildfire insurance, in electric rates.
Recovery of Wildfire-Related Costs
California courts have previously found investor-owned utilities to be strictly liable for property damage, 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. The rationale stated by these courts for applying this theory to investor-owned utilities is that property damages resulting from a public improvement, such as the distribution of electricity, can be spread across the larger community that benefited from such improvement.improvement through recovery of uninsured wildfire-related costs in electric rates. However, in November 2017, the CPUC issued a decision denying SDG&E's request to include in its rates uninsured wildfire-related costs arising from several 2007 fires,wildfires, finding that SDG&E did not prudently manage and operate its facilities prior to or at the outset of the 2007 wildfires.
When In July 2018, the CPUC denied both SDG&E's application for rehearing on its cost recovery request and a joint application for rehearing filed by SCE and PG&E limited to the applicability of inverse condemnation principles in the same proceeding. The California Court of Appeal and the California Supreme Court have denied SDG&E's petitions for review of the CPUC's denial of SDG&E's application.
In September 2018, California Senate Bill 901 ("SB 901") was signed by the Governor of California. Although SB 901 does not address the strict liability standard imposed by courts in inverse condemnation actions, the bill as enacted introduces a number of considerations the CPUC can apply to determine whether costs are recoverable in electric rates for wildfires occurring on or after January 1, 2019, including, among other things, the utility's actions, circumstances beyond the utility's control and the impact of extreme climate conditions. SB 901 requires investor-owned utilities to prepare annually, for CPUC approval, wildfire risk mitigation plans, and compliance with an approved plan is heldone of the factors that the CPUC can consider in addressing cost recovery. On February 6, 2019, in compliance with SB 901, SCE filed its wildfire mitigation plan


for 2019. While SCE takes the position in its wildfire mitigation plan that substantial compliance with the plan, once approved, will demonstrate that SCE prudently operated its system and met the CPUC's prudent manager standard regarding wildfire risk mitigation, the CPUC may not agree with SCE's position. Pursuant to be applicablethe requirements of SB 901, a Commission on Catastrophic Wildfire Cost and Recovery was formed in January 2019 to a utility,examine, among other things, the socialization of catastrophic wildfire costs in an equitable manner. SB901 also provides an opportunity for utilities to securitize costs that are deemed just and reasonable by the CPUC for wildfires that occur after January 1, 2019 and, to the extent costs exceed the maximum amount the utility may be held liablecan pay without harming ratepayers or materially impacting the utility's ability to provide adequate and safe services, for property damageswildfires that occurred in 2017. Based on events and associated interest and attorney's fees. If inverse condemnationinformation available to date, SCE believes it is heldunlikely that it will seek to be inapplicableuse this mechanism to SCEsecuritize costs incurred in connection with the December 2017 Wildfires, SCE could be held liable for property damages and associated interest if the property damages were found to have been proximately caused by SCE's alleged negligence. If SCE is found negligent, SCE could also be held liable for, among other things, fire suppression costs, business interruption losses, evacuation costs, medical expenses and personal injury/wrongful death claims. These potential liabilities, in the aggregate, could be substantial. Additionally, SCE could potentially be subject to fines for alleged violations of CPUC rules and laws in connection with the December 2017 Wildfires.
SCE is aware of multiple lawsuits filed related to the Thomas Fire naming SCE as a defendant. Several of the lawsuits also name Edison International as a defendant and some of the lawsuits were filed as purported class actions. 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. The Chair of the California Judicial Council has ordered that the lawsuits be coordinated in the Los Angeles Superior Court. SCE expects to be the subject of additional lawsuits related to the Thomas Fire. The litigation could take a number of years to be resolved because of the complexity of the matters and the time needed to complete the ongoing investigations.
Given the preliminary stages of the investigations and the uncertainty as to the causes of the Thomas Fire, and the extent and magnitude of potential damages, Edison International and SCE are currently unable to predict the outcome of the claims made against SCE and Edison International or reasonably estimate a range of losses that may be incurred.
SCE has approximately $1 billion of wildfire-specific insurance coverage, subject to a self-insured retention of $10 million per occurrence, for wildfire-related claims for the period ending on May 31, 2018. SCE also has approximately $300 million of additional insurance coverage for wildfire-related occurrences for the period from December 31, 2017 to December 31, 2017/2018 which may be used in addition to the $1 billion in wildfire insurance for wildfire events occurring on or after December 31, 2017 and on or before May 31, 2018, and would be available for new wildfire events, if any, occurring after


May 31, 2018 and on or before December 30, 2018. Various coverage limitations within the policies that make up SCE's wildfire insurance coverage could result in material self-insured costs in the event of multiple wildfire occurrences during a policy period. Should responsibility for a significant portion of the damages related to the December 2017 Wildfires be attributed to SCE, SCE's insurance may not be sufficient to cover all such damages. In addition, SCE may not be authorized to recover its uninsured damages through electric service rates if, for example, the CPUC finds that the damages were incurred because SCE was not a prudent manager of its facilities.Wildfire/Mudslide Events.
Edison International and SCE are pursuingcontinue to pursue legislative, regulatory and legal strategies to address the application of a strict liability standard to wildfire-related damages without the ability to recover resulting damagescosts in electric rates. In April 2019, a strike force formed by California Governor Gavin Newsom released a report entitled Wildfires and Climate Change: California's Energy Future that sets forth, among other things, guiding principles for potential reform of California policies regarding wildfire liability. While this report recommended that the Commission on Catastrophic Wildfire Cost and Recovery, the California legislature and the strike force continue working to develop a solution for consideration by the Governor and the legislature, Edison International and SCE cannot predict whether or when there will be a comprehensive solution mitigating the significant risk faced by a California investor-owned utilityutilities related to wildfires will be achieved.
Montecito Mudslideswildfires.
In January 2018, torrential rainsApril 2019, in Santa Barbara County produced mudslides and flooding in Montecito and surrounding areas (the "Montecito Mudslides"). According to Santa Barbara County initial reports, the Montecito Mudslides destroyed an estimated 135 structures, damaged an estimated 324 structures, and resulted in at least 21 fatalities, with two additional fatalities presumed.
Of the lawsuits mentioned above, several allege that SCE has responsibility for the Thomas Fire and that the Thomas Fire proximately caused the Montecito Mudslides, resulting in the plaintiffs' claimed damages. Some of the Montecito Mudslides lawsuits also name Edison International as a defendant. In addition to other causes of action, some of the Montecito Mudslides lawsuits also allege personal injury and wrongful death. The Chair of the California Judicial Council has ordered that the Thomas Fire and Montecito Mudslides lawsuits be coordinated in the Los Angeles Superior Court. SCE expects that additional lawsuits related to the Montecito Mudslides will be filed.
In the event that SCE is determined to have liability for damages caused by the Thomas Fire, SCE cannot predict whether the courts will conclude that the Montecito Mudslides were caused by the Thomas Fire or that SCE is liable for damages caused by the Montecito Mudslides. As a result, Edison International and SCE are currently unable to predict the outcome of the claims made against SCE and Edison International or reasonably estimate a range of losses that may be incurred. If it is determined that the Montecito Mudslides were caused by the Thomas Fire and that SCE is liable for damages caused by the Montecito Mudslides, then SCE's insurance coverage for such damages may be limitedrequested increases to its wildfire insurance.CPUC and FERC returns on common equity, SCE also has other general liability insurance coverage of approximately $450 million but it is uncertain whether these other policies would apply to liabilities alleged to be related to the mudslides. Additionally, if SCE is determined to be liable for a significant portion of costs associated with the Montecito Mudslides, SCE's insurance may not be sufficient to cover all such damages. In addition, SCE may not be authorized to recover its uninsured damages through electric service rates if, for example,requested from both the CPUC finds that the damages were incurred becauseand FERC an additional 6% return on common equity to compensate investors for current wildfire risk. SCE was notwould seek to reduce or remove this additional return on common equity if there is a prudent manager ofmaterial reduction in its facilities.
If it is ultimately determined that SCE is legally responsible for damages caused by the Montecito Mudslides and inverse condemnation is held to be applicable to SCE, SCE may be held liable for resulting property damages and associated interest and attorney's fees. If inverse condemnation is held to be inapplicable to SCE in connection with the Montecito Mudslides, SCE could be held liable for property damages and associated interest if the property damages were found to have been proximately caused by SCE’s alleged negligence. If SCE is found negligent, SCE could also be held liable for, among other things, business interruption losses, evacuation costs, clean-up costs, medical expenses and personal injury/wrongful death claims associated with the Montecito Mudslides. These potential liabilities, in the aggregate, could be substantial. SCE cannot predict whether it will be subjectedwildfire cost recovery risk due to regulatory fines related to the Montecito Mudslides.
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
In November 2014, the CPUC approved the San Onofre OII Settlement Agreement by and among The Utility Reform Network ("TURN"), the CPUC's Office of Ratepayers Advocates ("ORA"), San Diego Gas & Electric ("SDG&E"), the Coalition of California Utility Employees, and Friends of the Earth (the "Prior San Onofre Settlement Agreement"), which, at the time, 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 the Company not reporting certain ex parte communications on a timely basis, the Prior San Onofre Settlement Agreement remained reasonable, consistent with the law and in the public interest, which is the standard the CPUC applies in reviewing settlements submitted for approval.
Entry into Revised Settlement
On January 30, 2018, SCE, SDG&E, The Alliance for Nuclear Responsibility, The California Large Energy Consumers Association, California State University, Citizens Oversight dba Coalition to Decommission San Onofre, the Coalition of California Utility Employees, the Direct Access Customer Coalition, Ruth Henricks, ORA, TURN, and Women's Energy Matters (the "OII Parties") entered into a Revised San Onofre Settlement Agreement in the San Onofre OII proceeding (the "Revised San Onofre Settlement Agreement"). If approved by the CPUC, the Revised San Onofre Settlement Agreement will resolve all issues under consideration in the San Onofre OII and will modify the Prior San Onofre Settlement Agreement. If approved by the CPUC, the Revised San Onofre Settlement Agreement will also result in the dismissal of a federal lawsuit currently pending in the Ninth Circuit Court of Appeals challenging the CPUC's authority to permit rate recovery of San Onofre costs. The Revised San Onofre Settlement Agreement was the result of multiple mediation sessions in 2017 and January 2018 and was signed on January 30, 2018 following a settlement conference in the OII, as required under CPUC rules.
Implementation of the terms of the Revised San Onofre Settlement Agreement is subject to the approval of the CPUC, as to which there is no assurance. The OII Parties have agreed to exercise their best efforts to obtain CPUC approval, but there can be no certainty of when or what the CPUC will actually decide.
The San Onofre OII Assigned Commissioner and Assigned ALJ have issued joint rulings that, among other things, (i) direct the parties to submit joint testimony to the CPUC in support of the Revised San Onofre Settlement Agreement on April 27, 2018; (ii) direct all parties to submit briefing on whether an attorneys' fees provision in a related settlement agreement pertaining to the dismissal of a federal lawsuit challenging the Prior San Onofre Settlement Agreement impacts the integrity of the CPUC's intervenor compensation program; and (iii) schedule a public participation hearing and a status conference. In lieu of joint testimony, with the ALJ's consent, the parties submitted a joint stipulation of facts in support of the Revised San Onofre Settlement Agreement on April 27, 2018.
Disallowances, Refunds and Recoveries
If the Revised San Onofre Settlement Agreement is approved by the CPUC, SCE and SDG&E (the "Utilities") will cease rate recovery of San Onofre costs as of the date their combined remaining San Onofre regulatory assets equal $775 million (the "Cessation Date"). SCE has previously requested the CPUC to authorize SCE to reduce the San Onofre regulatory asset by applying $72 million of proceeds received from litigation with the DOE related to DOE's failure to meet its obligation to begin accepting spent nuclear fuel from San Onofre. If that request is approved by the CPUC, the Cessation Date is estimated to be December 19, 2017. If that request is not approved by the CPUC, the Cessation Date is estimated to be April 21, 2018. The Utilities will refund to customers San Onofre-related amounts recovered in rates after the Cessation Date. SCE will retain amounts collected under the Prior San Onofre Settlement Agreement before the Cessation Date. SCE also will retain $47 million of proceeds received in 2017 from arbitration with Mitsubishi Heavy Industries ("MHI") over MHI's delivery of faulty steam generators. In the Revised San Onofre Settlement Agreement, SCE retains the right to sell its stock of nuclear fuel and not share such proceeds with customers, as was provided in the Prior San Onofre Settlement Agreement. SCE intends to sell its nuclear fuel inventory as market conditions warrant. Sales of nuclear fuel may be significant.
Under the Prior San Onofre Settlement Agreement, the Utilities agreed to fund $25 million for a Research, Development and Demonstration program that is intended to develop technologies and methodologies to reduce greenhouse gas emissions ("GHG Reduction Program"). The Utilities' funding obligation is reduced to $12.5 million under the Revised San Onofre Settlement Agreement.


If approved by the CPUC, the Revised San Onofre Settlement Agreement will also provide certain exclusions from the determination of SCE's ratemaking capital structure. Notwithstanding that SCE will no longer recover its San Onofre regulatory asset, the debt borrowed to finance the regulatory asset will continue to be excluded from SCE's ratemaking capital structure. Additionally, SCE may exclude the after-tax charge resulting from the implementation of the Revised San Onofre Settlement Agreement from its ratemaking capital structure.
Additional Challenges related to the Settlement of San Onofre CPUC Proceedings
A federal lawsuit challenging the CPUC's authority to permit rate recovery of San Onofre costs and an application to the CPUC for rehearing of its decision approving the Prior San Onofre Settlement Agreement were filed in November and December 2014, respectively. In April 2015, the federal lawsuit was dismissed with prejudice and the plaintiffs in that case appealed the dismissal to the Ninth Circuit in May 2015. In light of the San Onofre OII meet-and-confer sessions, the Ninth Circuit cancelled the hearing that had been scheduled for February 9, 2017 and ordered the parties to notify the Ninth Circuit 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. As part of the Revised San Onofre Settlement Agreement, subject to CPUC approval of the Revised San Onofre Settlement Agreement, the plaintiffs agreed to dismiss this case with prejudice. In light of these developments, the February 13 hearing was cancelled and the Ninth Circuit appeal is currently stayed.
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 purports to be filed on behalf of a class of persons who acquired 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 a second amended complaint in October 2016, which the federal court dismissed again with an opportunity for the plaintiff to amend the complaint. Plaintiff filed a third amended complaint in May 2017, which the federal court dismissed with prejudice in March 2018. Plaintiffs' have appealed the dismissal.
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. In July 2016, the federal court granted 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.
Edison International and SCE cannot predict the outcome of these proceedings.legislative reform.
Environmental Remediation
SCE records its environmental remediation liabilities when site assessments and/or remedial actions are probable and a range of reasonably likely cleanup costs can be estimated. 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 March 31, 2018,2019, SCE's recorded estimated minimum liability to remediate its 2021 identified material sites (sites with a liability balance at March 31, 2018,2019, in which the upper end of the range of the costs is at least $1 million) was $142$136 million, including $92$89 million related to San Onofre. In addition to these sites, SCE also has 1615 immaterial sites with a liability balance as of March 31, 2018,2019, for which the total minimum recorded liability was $4 million. Of the $146$140 million total environmental remediation liability for SCE, $140$135 million has been recorded as a regulatory asset. SCE expects to recover $47$43 million through an incentive mechanism that allows SCE to recover 90% of its environmental remediation costs at certain sites (SCE may request to include additional sites) and $93$92 million through a mechanism that allows SCE to recover 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 $131$138 million and $8$7 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 30 years. Remediation costs for each of the next five years are expected to range from $4$7 million to $18$24 million. Costs incurred for the three months ended March 31, 2019 and 2018 were $2 million and 2017 were $4 million, and $2 million, respectively.


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, 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 $50 million and $1.06 billion, respectively. If 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 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 $13.1$14.1 billion for Palo Verde and $560 million for San Onofre. 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 ("ANI"). 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 $60$65 million per nuclear incident for future incidents. However, it would have to pay no more than approximately $9$10 million per future incident in any one year. SCE could be required to pay a maximum of approximately $255 million per nuclear incident 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.
For more information on nuclear insurance coverage, see Note 11 in the 2017 Form 10-K.
Spent Nuclear Fuel
Under federal law, the DOE is responsible for the selection and construction of a facility for the permanent disposal of spent nuclear fuel and high-level radioactive waste. The DOE 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(SCE's 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(SCE's share $124 million, which included reimbursement for approximately $2 million in legal costs (SCE share $124 million)and other costs), 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. In August 2018, the CPUC approved SCE's proposal to return the SCE share of the award to customers based on the amount that customers actually contributed for fuel storage costs; resulting in approximately $105.6 million of the SCE share being returned to customers and the remaining $16.6 million being returned to shareholders. Of the $105.6 million, $71.6 million was applied against the remaining San Onofre Regulatory Asset in accordance with the Revised San Onofre Settlement Agreement.
The April 2016 settlement also providesprovided for a claim submission/audit process for expenses incurred from 2014 – 2016, where SCE may 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 makemade additional legal action to recover damages incurred in 2014 – 2016–2016 unnecessary. The first such claim covering damages for 2014 – 2015 was filed on September 30, 2016 for approximately $56 million. In February 2017, the DOE reviewed the 2014 – 2015 claim submission and reduced the original request to approximately $43 million (SCE(SCE's share was approximately $34 million). 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 $58 million. In MarchMay 2018, the DOE completed its reviewapproved reimbursement of SCE’sapproximately $45 million (SCE's share was approximately $35 million) of SCE's 2016 claim submission and determined that SCE should be reimbursed approximately $44 million, not allowingdamages, disallowing recovery of approximately $14$13 million. In April 2018, SCE submitted a request for reconsiderationaccepted the DOE's determination, and the government paid the 2016 claim under the terms of the DOE's March 2018 determination, requesting that the DOE allow recovery of an additional $1.2 million.

The damages recovered by SCEawards are subject to CPUC review as to how thesethe amounts wouldwill be distributedrefunded among customers, shareholders, or to offset fuel decommissioning or storageother costs.


Note 13.    Leases
Leases as Lessee
SCE has entered into various agreements to purchase power, electric capacity and other energy products that may be accounted for as leases as SCE has dispatch rights that determine when and how a plant runs. Prior to January 1, 2019, a power purchase agreement contained a lease when SCE purchased substantially all of the output from a specific plant and did not otherwise meet a fixed price unit of output exception. SCE also leases property and equipment primarily related to vehicles, office space and other equipment. The terms of the contracts included in the table below are 5 to 20 years for PPA leases, 5 to 72 years for office leases, and 5 to 12 years for the remaining other operating leases.
The following table summarizes SCE's lease payments for operating and finance leases as of March 31, 2019.

LEGAL PROCEEDINGS
Thomas Fire and Koenigstein Fire Litigation
In December 2017, Wildfires Litigation
The December 2017 Wildfireswind-driven wildfires impacted portions of SCE's service territory, and causedcausing substantial damage to both residential and business properties and service outages for SCE customers. The VCFD and CAL FIRE have determined that the largest of thesethe 2017 fires knownoriginated on December 4, 2017, in the Anlauf Canyon area of Ventura County (the investigating agencies refer to this fire as the Thomas Fire, originated in Ventura County and burned acreage located in both Ventura and Santa Barbara Counties."Thomas Fire"), followed shortly thereafter by the Koenigstein Fire. According to the most recent Cal Fire incidentCAL FIRE information, reports, the Thomas Fireand Koenigstein Fires burned over 280,000 acres, destroyed or damages an estimated 1,063 structures, damaged an estimated 2801,343 structures and resulted in one fatality.two fatalities.
As of April 27, 2018,26, 2019, SCE was aware of at least 52151 lawsuits, representing approximately 2,300 plaintiffs, related to the Thomas Fireand Koenigstein Fires naming SCE as a defendant. SeventeenSeventy-eight of these lawsuits also name Edison International as a defendant based on its ownership and atalleged control of SCE. At least four of the lawsuits were filed as purported class actions. 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. The Chair of the California Judicial Council has ordered that the lawsuits behave been coordinated in the Los Angeles Superior Court.
For further information, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides."
Montecito Mudslides Litigation
In January 2018, torrential rains in Santa Barbara County produced mudslides and flooding in Montecito and surrounding areas. According to Santa Barbara County initial reports, the Montecito Mudslides destroyed an estimated 135 structures, damaged an estimated 324 structures, and resulted in at least 21 fatalities, with two additional fatalities presumed.
Twenty-nineSixty-eight of the 52151 lawsuits mentioned under "December 2017 Wildfires"Thomas Fire and Koenigstein Fire Litigation" above allege that SCE has responsibility for the Thomas Fireand/or Koenigstein Fires and that the Thomas Fireand/or Koenigstein Fires proximately caused the Montecito Mudslides, resulting in the plaintiffs’plaintiffs' claimed damages. ElevenTwenty-seven of the 68 Montecito Mudslides lawsuits also name Edison International as a defendant.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. The Chair ofThomas and Koenigstein Fires lawsuits and the California Judicial Council has ordered that the Thomas Fire and Montecito Mudslides lawsuits behave been coordinated in the Los Angeles Superior Court.

For further information, see "Notes to Consolidated Financial Statements—Note 12. Commitments and Contingencies—Contingencies—Southern California Wildfires and Mudslides."


Woolsey Fire Litigation
In November 2018, wind-driven wildfires impacted portions of SCE's service territory and caused substantial damage to both residential and business properties and service outages for SCE customers. The largest of these fires, known as the Woolsey Fire, originated in Ventura County and burned acreage located in both Ventura and Los Angeles Counties. According to CAL FIRE information, the Woolsey Fire burned almost 100,000 acres, destroyed an estimated 1,643 structures, damaged an estimated 364 structures and resulted in three fatalities.
As of April 26, 2019, SCE was aware of at least 72 lawsuits, representing approximately 1,100 plaintiffs, related to the Woolsey Fire naming SCE as a defendant. Fifty-eight of these lawsuits also name Edison International as a defendant based on its ownership and alleged control of SCE. At least two of the lawsuits were filed as purported class actions. 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. The Woolsey Fire lawsuits have been coordinated in the Los Angeles Superior Court.
