Letter to Shareholders 

I am privileged to address you in my first letter to 
shareholders as president and chief executive officer  
of Edison International. It is humbling to lead a company 
with a 130-year history as one of the builders of 
the Southern California region and a recognized 
innovator in the electric power industry. Since 
assuming the role of CEO on October 1 after leading 
our Southern California Edison (SCE) utility, I have 
become ever more impressed by the skill and 
dedication our team demonstrates every day serving 
our customers, at both SCE and our Edison Energy 
Group (EEG) of competitive businesses. 

Our team will be asked to respond to new and 
greater challenges and opportunities in the coming 
years. Our company, our industry, and our global 
economy are all in the midst of a profound transition. 
New technologies are rapidly changing the electric 
power landscape, giving customers and utilities alike  
greater choices and creating new ways to work 
more efficiently in every industry. Moreover, the 
electric grid is emerging as a critical enabler of carbon 
reduction across the entire economy, not just the 
power sector, in order to address climate change.

While federal policies are evolving, the state of 
California will continue to pursue greenhouse gas 
reduction, and our company will be a key player in 
this effort. Our customers and state policymakers 
demand it. One of our key responsibilities is to work 
constructively with government at the federal, state, 
and local levels. We look to find areas where we can 
work together, make an impact, and do right by our 
customers, employees and stakeholders. 

Edison International is uniquely positioned to lead 
the transformative change underway in the electric  
power industry. This leadership provides opportunities 
for growth and adding value for our shareholders 
while serving the interests of our customers, our 
state, and the environment. 

In 2016, we generated strong returns for shareholders. 
Edison International’s stock price closed 2016 up 
22 percent. Our stock outperformed our primary 
benchmark, the Philadelphia Utilities Index, which 
rose 13 percent in 2016. The S&P 500 Index rose 

10 percent. Including the dividend, total return for 
shareholders in 2016 was 25 percent, compared to 
17 percent for the Philadelphia Utilities Index and  
12 percent for the S&P 500.

In December, we increased our dividend for the  
thirteenth consecutive year to an annual rate of 
$2.17 per share – a 13 percent increase. This was 
the third consecutive year we announced a double- 
digit increase, and reflected our commitment to 
returning our dividend in steps over time to our 
target payout ratio of 45 to 55 percent of SCE’s 
earnings. Dividend growth remains an important 
element of Edison International’s value proposition 
for investors as we target dividend growth at a 
faster pace than SCE’s earnings growth.

Core earnings in 2016 were $3.97 per share and our 
GAAP earnings were $4.02 per share. (See opposite 
page for a reconciliation of core and GAAP earnings.) 
These results compared to 2015 earnings of $4.10 
and $3.13 per share, on the same basis. 

Next, I want to review the operational and strategic 
highlights of 2016 and priorities for 2017 at each of 
our operating companies. 

At SCE, our business strategy has three key elements. 
First, maintain a safe and reliable wires network. 
Second, be a key enabler of California’s commitment 
to greenhouse gas reduction, led by our proposed 
grid modernization efforts to support widespread 
adoption of renewable and distributed energy, storage, 
electric vehicle charging, and other technologies. 
And finally, continue our operational excellence 
journey to achieve top quartile performance in 
safety, reliability, customer satisfaction, and costs.

Looking ahead to 2017, a major priority for SCE will  
continue to be safety. Although we have made 
progress on our journey to injury-free in recent 
years, we must further intensify our focus on 
employee and public safety. To that end, we have 
elevated safety to one of our company’s six core 
values. To increase our engagement and dedicate 
additional senior leadership in this area, we have 
created a new officer position at SCE: Vice President 
of Safety, Security and Business Resiliency. We aim 

Edison International and Southern California Edison 2016 Annual Report 

Page 2

to eliminate serious injuries and fatalities and  
protect our colleagues and customers from all types 
of injuries. 

On September 1, we filed SCE’s 2018 General Rate 
Case at the California Public Utilities Commission. 
This filing, which seeks to set customer rates for the 
years 2018-2020, demonstrates our commitment 
to SCE’s three strategy elements. We believe we 
have made a strong case for our strategy and the 
requested funding levels in our filing.

The grid modernization efforts included in our rate 
request will support California’s implementation of  
Senate Bill 32, signed by Governor Brown on 
September 8. This legislation requires the state to 
cut greenhouse gas emissions 40 percent below 
1990 levels by 2030 in order to help address global 
climate change. 

We believe that California will have to move much 
more aggressively than it has in the past -- and 
sooner rather than later -- to meet these new 
legislative mandates within a short 13 years. Many 
of California’s policies to date have focused on 
electric power generation, but that represents only  
an estimated 20 percent of current statewide 
greenhouse gas emissions. The largest source is the 
transportation sector, with an estimated 36 percent 
of current emissions. We believe that substantial 
new efforts across all sectors of the economy will 
be needed, and many of these efforts will require 

significant electrification of sectors that today rely 
on fossil fuels. Grid modernization is an important 
part of the needed solution, and we see ourselves 
as a key partner with California in this effort.

SCE is continuing to advance the electrification of 
transportation in California. In January of 2017, we 
and other investor-owned utilities filed applications 
at the Public Utilities Commission laying out a  
path for using transportation electrification to help 
meet the state’s greenhouse gas reduction goals. 
Transportation electrification is also an opportunity  
to improve the health and environment for many 
communities located near major transportation  
corridors and encourage investment in 
disadvantaged communities.

In addition, at year-end 2016, SCE installed 40 
megawatts of company-owned battery storage across  
three projects on our system, including the industry’s 
first installations of batteries fully integrated into 
peaking generation stations. The combination of 
these projects and battery storage competitively 
procured in the past 18 months makes SCE the 
largest battery storage owner and purchaser of 
battery storage services in North America as we move 
to better integrate renewable energy resources.

In December, we received a ruling from the Public  
Utilities Commission on SCE’s settlement regarding 
the retired San Onofre Nuclear Generating Station. 
The ruling directed SCE to confer with other parties  

Edison International’s senior leadership team: Center front – Pedro J. Pizarro, President and Chief Executive Officer;  
Middle row, left to right -- Gaddi H. Vasquez, Senior Vice President, Government Affairs; Jacqueline Trapp, Vice President, Human 
Resources; Maria C. Rigatti, Executive Vice President and Chief Financial Officer; Adam S. Umanoff, Executive Vice President and Gen-
eral Counsel; Back row, left to right -- Ronald O. Nichols, President, Southern California Edison; Ronald L. Litzinger, President, Edison 
Energy Group;  Kevin M. Payne, Chief Executive Officer, Southern California Edison;  Janet T. Clayton, Senior Vice President, Corporate 
Communications; J. Andrew (Drew) Murphy, Senior Vice President, Strategic Planning.

Edison International and Southern California Edison 2016 Annual Report

about possibly changing the terms of our previously  
approved 2014 settlement. While we continue to  
believe the previous settlement reflects a good  
outcome for our customers, we are participating in  
the process spelled out in the ruling. Also in  
December, SCE selected a joint venture between  
AECOM and EnergySolutions as the decommissioning 
general contractor to dismantle San Onofre starting 
in 2018. This is an important milestone in our 20-year 
plan to safely decommission the plant.

At our Edison Energy Group of competitive 
businesses, we are leveraging our insights into the  
transformation underway in the electric power 
industry by building new businesses primarily outside  
of our Southern California footprint. Though small 
today, EEG shows great promise. Its principal 
businesses are in energy advisory services and  
solutions for large commercial and industrial customers.  
This includes commercial and community solar, 
energy procurement advisory, arranging contracts 
for renewable energy sourced away from the 
customer’s location, and energy efficiency and energy 
management capabilities. We see great potential 
in integrating these into a broader “energy as a 
service” product for customers throughout the U.S. 

Feedback from the marketplace has been quite 
encouraging. Our customers include a number of 
Fortune 1000 companies and a dozen of the Fortune 
50. For example, our team worked with General 
Motors to identify renewable energy projects in Texas, 
and then helped GM execute its largest wind deal 
to date, which will allow 16 of its facilities to be 
powered with 100 percent renewable energy by 2018. 

We still have much work to do to flesh out a 
compelling value proposition that will grow this 
into a profitable business with meaningful scale. 
We expect to complete evolving our initial business 
case into a detailed business plan by the fall of 
2017 with near-term milestones that our board, 
management, and investors can use to measure 
our progress. I am committed to implementing 
our competitive business strategies at a pace that 
creates opportunities for meaningful growth, yet is 
a disciplined, capital-light approach that does not 
detract from Edison International’s opportunity to 
deliver above industry average earnings and dividend 
growth and resulting value for investors.

I want to express my gratitude to the Edison 
International board of directors for their guidance 
and support. I especially want to thank retiring 
directors Richard T. Schlosberg III and Jagjeet S. 
Bindra for their years of service, and to welcome our 
newest board member, Louis Hernandez Jr. I look 
forward to working with the board under our new 
governance model with myself as CEO and William 
P. Sullivan as chair. I also want to salute Ted Craver 
and Jim Scilacci, who retired in 2016 as Edison 
International’s chief executive officer and chief 
financial officer, respectively. Ted and Jim left our 
company on sound footing for the future.

Our companies – both Southern California Edison 
and Edison Energy Group – are grounded in a 
common set of values. At the core, we’re wired the 
same way in wanting our teams to serve customers 
with respect and integrity, and always pushing 
ourselves to get better. We have the drive, insights, 
and innovation to successfully lead our industry’s 
transformation and to deliver safe, reliable, clean, 
and affordable energy. My talented and dedicated 
teammates at Edison International are ready to do 
remarkable things.

 Tomorrow’s Clean Energy Economy: Customer-driven. Modernized. Reliable.

Modernizing the Grid at Southern California Edison 
Amid a profound shift underway in the energy business,
we are building the power grid of the future.

Today’s customers are adopting distributed energy resources – rooftop solar,  
onsite storage, electric vehicles, and energy management systems – to achieve cost  
savings, cleaner power, conservation, and enhanced reliability. California is at 
 the forefront of this power system transformation and is home to 50 percent of the  
nation’s private solar systems – more than half a million businesses and homes.   
In response, we at SCE are modernizing and reinforcing the grid to enable customers  
to maximize the value of their investments. This will not only benefit individual  
customers, but also will contribute significantly to local economies, a cleaner 
 environment, and grid resiliency. 

Photo above: SCE’s Grid Control Center is at the heart of an  
electricity distribution network that is becoming smarter – more digital,  
resilient, and capable of accommodating new energy technologies  
that customers plug in to the system.

Reducing Emissions with Battery Storage 
Large-scale batteries are emerging today as viable alternatives  
to running carbon-emitting power plants.

Recent advances in the cost and efficiency of battery technologies have  
created an opportunity to store larger amounts of electricity on the grid to 
 be used when needed, thereby reducing reliance on fuel-burning power plants.  
After testing this technology with demonstration projects for several years,  
we completed three major installations of grid battery storage in 2016. We contracted  
with Tesla Energy for the construction of a 20-megawatt battery storage facility  
at our Mira Loma substation in Ontario, California, and with General Electric  
for the construction of two innovative 10-megawatt battery storage facilities 
integrated with our peaker plants in Norwalk and Rancho Cucamonga. 

Photo above: At our gas-fired peaker plant in Norwalk is one of two of the 
 world’s first battery and gas turbine hybrid systems. These systems are capable  
of responding instantaneously to electric system needs while simultaneously  
reducing greenhouse gas emissions and operating costs, a revolutionary  
approach to renewable integration and system reliability.

 Tomorrow’s Clean Energy Economy: Customer-driven. Modernized. Reliable.

Enabling a Transportation Revolution
Converting the transportation sector from petroleum to electricity 
is a key to meeting the climate challenge.

The largest source of greenhouse gas in California is the transportation sector,  
with an estimated 36 percent of current emissions. A key priority for the state  
is advancing the electrification of transportation. At SCE, we launched in 2016  
our Charge Ready pilot to install 1,500 electric vehicle charging stations at “long-dwell”  
locations such as apartment and office buildings. In January 2017, we filed an application 
with state regulators laying out a path for using transportation electrification to help 
 meet the state’s greenhouse gas reduction goals while improving the health  
and environment for many communities located near major transportation corridors 
 and encouraging investment in disadvantaged communities. 

Photos above: With new dedicated power circuits and a substation, SCE is  
supporting the Port of Long Beach on its Middle Harbor Project, which  
includes emissions-reducing electric-powered equipment such as ship-to-shore  
and rail-mounted gantry cranes and autonomous guided vehicles. 
 Inset: Electric car plugging in to an SCE Charge Ready site.

Energy Services at Edison Energy Group
At EEG, we are building new businesses in energy services  
for large commercial and industrial customers.

In its first full year of operation in 2016, Edison Energy Group added Altenex,  
Delta Energy and ENERActive Solutions, and, along with SoCore Energy,  
now offers a wide range of energy advisory services and solutions to businesses  
across the country, including many in the Fortune 1000. For example, our team  
worked with General Motors to analyze its overall energy portfolio, with the  
objective of reducing energy costs, lowering the carbon footprint and limiting  
risk from energy cost volatility. The team also reached a three-year agreement  
with the San Diego Unified Port District to provide energy consulting and reporting  
services aimed at reducing emissions and optimizing its energy management. 

Photo above: SoCore Energy helped Dairyland Power Cooperative go solar with an 18-megawatt 
project at 14 sites across Wisconsin and Iowa, which was recognized by PV Conference & Expo 
 in Chicago as one of the best photovoltaic projects in the Midwest. Also in 2016, SoCore agreed to 
acquire a number of solar garden development projects in Minnesota, and signed a 25-year power 
purchase agreement to provide solar power to the Port of Long Beach.

Edison International's earnings are prepared in accordance with GAAP used in the United States. Management uses core 
earnings 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 investor under the HLBV accounting method and income or loss from significant discrete 
items that management does not consider representative of ongoing earnings, such as: exit activities, including sale of certain 
assets and other activities that are no longer continuing, write downs, asset impairments and other gains and losses related to 
certain tax, regulatory or legal settlements or proceedings. 

Edison International's 2016 earnings increased $291 million, driven by an increase in SCE's earnings of $378 million 
partially offset by increased costs at Edison International Parent and Other and lower income from discontinued operations. 
SCE's increased net income consisted of $8 million of higher core earnings and $370 million of higher non-core earnings. 
The increase in core earnings was due to an increase in revenue from the escalation mechanism set forth in the 2015 GRC 
decision and lower operations and maintenance expenses, partially offset by higher net financing costs and tax expense.

Edison International Parent and Other results for 2016 consisted of $50 million of higher core losses and $14 million of lower 
non-core earnings. During 2016, Edison International Parent and Other recorded an after-tax charge of $13 million related to 
the buy-out of an earn-out provision with the former shareholders of a company acquired by Edison Energy at the end of 
2015. The buy-out was completed, together with modification to employment contracts, in order to align long-term incentive 
compensation. In addition, core losses for 2016 included higher operating and development costs and lower revenue and 
gross margin from the sale of solar systems at Edison Energy Group. Results during 2015 included income from Edison 
Capital's investments in affordable housing projects, which were sold at the end of 2015.

Consolidated non-core items for 2016 and 2015 for Edison International included:

•  SCE's write-down of $382 million in 2015 of regulatory assets previously recorded for recovery of deferred income taxes 

from 2012 – 2014 incremental tax repair deductions. 

• 

• 

• 

Income of $20 million ($12 million after-tax) in 2015 at SCE related to shareholder's portion of NEIL insurance 
recoveries arising from the outage and shutdown of the San Onofre Units 2 and 3 generating stations and the recovery of 
legal costs. 

Income of $16 million ($10 million after-tax) in 2015 related to completion of the sale of Edison Capital's affordable 
housing investment portfolio which represented the exit from this business activity.

Income of $5 million and $9 million for 2016 and 2015, respectively, related to losses (net of distributions) allocated to 
tax equity investors under the HLBV accounting method. Edison International reflected in core earnings the operating 
results of the solar projects, related financings and the priority return to the tax equity investor. The losses allocated to 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 "Notes to Consolidated Financial Statements—Note 1. 
Summary of Significant Accounting Policies."

• 

Income from discontinued operations, net of tax, was $12 million and $35 million for 2016 and 2015, respectively, 
primarily related to the resolution of tax issues related to EME. The discontinued operations from 2015 also reflects 
proceeds from insurance recoveries related to EME. See "Notes to Consolidated Financial Statements—Note 7. Income 
Taxes" for further information.

See "Results of Operations" for discussion of SCE and Edison International Parent and Other results of operations, including 
a comparison of 2015 results to 2014. 

Electricity Industry Trends

The electric power industry is undergoing transformative change driven by technological advancements such as customer-
owned generation and energy storage, which could alter the nature of energy generation and delivery. California's 
environmental policy objectives are accelerating the pace and scope of the industry change. The electric grid is a critical 
enabler of the adoption of new energy technologies that support California's climate change and GHG reduction objectives, 
which continue to be publicly supported by California policy makers notwithstanding a potential change in the federal 
approach to such matters. The grid is also key to enabling more customer choices with respect to new energy technologies. 
The transformative change taking place in the electric power industry is integral to Edison International's strategy.

SCE plans to be a key enabler of the adoption of new energy technologies that benefit customers of the electric grid while 
also helping the state of California achieve its environmental goals. SCE expects to achieve these objectives through 
modernizing the electric grid to improve the safety and reliability of the transmission and distribution network and enabling 
increased penetration of DERs. SCE's ongoing focus to drive operational and service excellence should allow it to achieve 
these objectives while controlling costs and customer rates. SCE's focus on the transmission and distribution side of the 
utility business aligns with California's policy supporting competitive power markets. It also represents a lower risk than 
investment in conventional, natural gas-fired generation, which faces potentially stricter GHG limits as well as the increasing 
competitiveness of renewable resource fueled generation. For more information on the distribution grid development, see "—
Capital Program—Distribution Grid Development" below. 

4

Changes in the electric power industry are impacting customers and jurisdictions outside California as well. Edison 
International believes that other states will also pursue climate change and GHG reduction objectives, even if the federal 
approach to such objectives changes, and large commercial and industrial customers will continue to pursue cost reduction 
and sustainability goals. Edison Energy Group provides energy services to large commercial and industrial customers who 
may be impacted by these changes. Edison Energy Group seeks to provide advice in dealing with increasingly complex tariff 
and technology choices in order to support customers and their management of energy costs and risks. 

Capital Program

Total capital expenditures (including accruals), were $3.5 billion in 2016. SCE's year-end rate base was $25.9 billion at 
December 31, 2016 compared to $24.6 billion at December 31, 2015. 

To support a safe and reliable transmission and distribution network, and to modernize the electric grid to enable increased 
penetration of DERs, SCE forecasts capital expenditures of up to $19.3 billion for 2017 – 2020. The capital forecast for 
2017 – 2020 reflects updates primarily to reflect the delay in receipt of project approvals on the West of Devers project and 
the Mesa Substation project (see "Liquidity—Capital Investment Plan" for further information). The forecasted CPUC capital 
expenditures include traditional capital spending, such as infrastructure replacement and maintenance, expansions and 
additions due to load growth and work requested by customers, as well as expenditures for grid modernization to support 
improved safety and reliability and increased levels of DERs. Traditional capital spending for 2017 reflects SCE's forecast 
capital expenditures for CPUC and FERC capital projects. Also included in 2017 capital expenditures is a baseline of grid 
modernization spending that will promote increased safety and reliability and also allow for a timely ramp-up of grid 
modernization capital expenditures in subsequent years. SCE has requested CPUC approval of a memorandum account to 
facilitate recovery in rates of such expenditures. The memorandum account has not yet been approved by the CPUC. SCE 
may receive further guidance on grid modernization spending from the CPUC as part of the DRP proceeding in the second 
half of 2017. Traditional capital expenditures for 2018 – 2020 reflect the amounts requested in the 2018 GRC filing and 
FERC capital projects. The CPUC has approved 81%, 89% and 92% of the traditional capital expenditures requested in the 
2009, 2012 and 2015 GRC decisions, respectively. While SCE cannot predict the level of traditional capital spending that will 
be approved in the 2018 GRC decision, management is not aware of factors that would cause the percentage of SCE's request 
that is ultimately approved to be materially different from what has been approved in recent GRC decisions. SCE does not 
have prior approval experience with grid modernization capital expenditures and, therefore, is unable to predict an expected 
outcome. 

Forecasted expenditures for FERC capital projects is subject to timely receipt of permitting, licensing and regulatory 
approvals. The following table sets forth a summary of capital expenditures for 2016 actual spend and a forecast for 
2017 – 2020 on the basis described above:

Capital expenditures for traditional capital projects under CPUC jurisdiction for 2017 are included in SCE's 2015 GRC. The 
2018 – 2020 capital expenditures are included in the 2018 GRC application request discussed below. Recovery for 
2017 – 2020 planned expenditures for traditional capital projects under FERC jurisdiction will be pursued through FERC-
authorized mechanisms. For further information regarding the capital program, see "Liquidity and Capital Resources—SCE

Distribution Grid Development

Distribution Resources Plan 

In July 2015, SCE filed its DRP with the CPUC. The filing was made as part of a CPUC proceeding that was initiated to 
support California's climate change and GHG reduction targets, modernize the electric distribution system to accommodate 
two-way flows of energy associated with DERs, such as rooftop solar, and facilitate customer choice of new technologies and 
services that reduce emissions and improve resilience. SCE's DRP included an indicative forecast of capital investment in 
distribution automation, substation automation, communications systems, technology platforms and applications, and grid 
reinforcement. The 2018 GRC includes operation and maintenance and capital expenditure requests consistent with SCE's 
DRP operation and maintenance and capital spending. Capital investments for 2017 may be updated or revised based on 
developments and guidance received from the CPUC as a part of the GRC, DRP rule making, technology availability, pace of 
DER adoption, and other factors. In January 2016, the CPUC issued a scoping memo that provided for the issuance of 
guidance on utility spending to modify its grid in order to support its DRP. SCE expects to receive such guidance in the 
second half of 2017.

Charge Ready Program

In January 2016, the CPUC approved SCE's $22 million Charge Ready Phase 1 pilot program, which will allow SCE to 
install light-duty vehicle charging infrastructure, provide rebates to offset the cost of qualified customer-owned charging 
stations, and implement a supporting market education effort. Under the Phase 1 pilot program, SCE will build, own and 
maintain the electric infrastructure needed to serve the qualified charging stations at participating customer locations. 
Participating customers will install, own, maintain, and operate the charging stations. By the end of January 2017, SCE had 
executed agreements for 50 sites to deploy 776 charge ports. The results of this pilot will help shape Phase 2 of the program. 
SCE will file an application to obtain CPUC approval for Phase 2 after at least one year (Phase 1 launched in late May 2016) 
and 1,000 charge ports have been deployed. 

Transportation Electrification Plan

In January 2017, SCE filed a transportation electrification plan with the CPUC that aims 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 discussed above. The proposal has an estimated five-year cost of $554 million ($532 million capital) in 2016 
dollars. In addition, the plan proposes six pilot projects to be considered by the CPUC on an accelerated basis. The pilot 
projects would install charging infrastructure for electric transit buses and the Port of Long Beach; build clusters of fast 
charging sites in urban areas, and establish programs that would incentivize electric vehicle adoption. The estimated total cost 
of the six pilot projects is approximately $19 million ($14 million capital) in 2016 dollars. SCE expects to propose additional 
programs and pilots in the future.

All of the plan's proposed transportation electrification projects are subject to CPUC review and the timing and amount of 
capital investments for any approved project will depend upon implementation decisions, including scope and pace of 
adoption and GRC ratemaking decisions and other CPUC actions. SCE is unable to predict an expected outcome on or timing 
of implementation of any of the proposed projects. The capital costs for these proposed projects are not included in SCE's 
capital spending and rate base forecasts provided above.

Edison International Dividend Policy

In December 2016, Edison International declared a 13% increase to the annual dividend rate from $1.92 per share to 
$2.17 per share. Edison International plans to increase its dividends to common shareholders at a higher than industry 
average growth rate within its target payout ratio of 45% to 55% of SCE earnings in steps over time. This is expected to yield 
a dividend growth at a faster pace than SCE's earnings growth.

Regulatory Proceedings

2018 General Rate Case

In September 2016, SCE filed its 2018 GRC application for the three-year period 2018 – 2020, which requested a 2018 
revenue requirement of $5.885 billion, an increase of $222 million over the projected 2017 GRC authorized revenue 
requirement. In addition, SCE requested $48 million in one-time balancing and memorandum account recoveries. This 
represents a 2.7% increase over presently authorized total rates. SCE's 2018 GRC request also includes proposed revenue 
requirement increases of $533 million in 2019 and $570 million in 2020. For 2019 and 2020, respectively, these represent 
4.2% and 5.2% increases over presently authorized total rates. 

The capital programs requested in SCE's 2018 GRC are focused on safety and reliability through investments in the 
distribution grid to replace aging equipment and enhance capabilities to integrate increasing amounts of DERs. For further 
information, see "—Capital Program" above.

SCE's 2018 GRC request identifies areas of reduced operating cost to partially mitigate the customer rate impacts of the 
request.

SCE requested that the CPUC issue a final decision by the end of 2017. If the schedule for a final decision is delayed, SCE 
will request the CPUC to issue an order directing that the authorized revenue requirement changes be effective January 1, 
2018. SCE cannot predict the revenue requirement the CPUC will ultimately authorize for 2018 through 2020 or forecast the 
timing of a final decision. 

Permanent Retirement of San Onofre

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

San Onofre CPUC Proceedings

In November 2014, the CPUC approved the San Onofre OII Settlement Agreement, which resolved the CPUC's investigation 
regarding the steam generator replacement project at San Onofre and the related outages and subsequent shutdown of San 
Onofre. Subsequently, the San Onofre OII proceeding record was reopened by a joint ruling of the Assigned Commissioner 
and the Assigned ALJ to consider whether, in light of the Company not reporting certain ex parte communications on a 
timely basis, the San Onofre OII 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. In comments filed with the 
CPUC in July 2016, SCE asserted that the Settlement Agreement continues to meet this standard and therefore should not be 
disturbed. A number of the parties to the OII, however, have requested that the CPUC either modify the San Onofre OII 
Settlement Agreement or vacate its previous approval of the settlement and reinstate the OII for further proceedings. 

In a December 2016 joint ruling, the Assigned Commissioner and the Assigned ALJ expressed concerns about the extent to 
which the failure to timely report ex parte communications had impacted the settlement negotiations and directed SCE to 
meet and confer with the other parties in the OII to consider changing the terms of the San Onofre OII Settlement Agreement. 
The ruling set out a schedule requiring that at least two meet and confer sessions be held in the first quarter of 2017 and 
requiring the parties to submit a joint status report to the CPUC by April 28, 2017 if no modifications have been agreed to by 
some or all of the parties as a result of the meet and confer process. SCE has recorded a regulatory asset to reflect the 
expected recoveries under the San Onofre OII Settlement Agreement. At December 31, 2016, $857 million remains to be 
collected. 

For more information on the challenges to the settlement of the San Onofre OII and the claims that SCE is pursuing against 
MHI, see "Notes to Consolidated Financial Statements—Note 11. Commitments and Contingencies—Contingencies—San 
Onofre Related Matters."

Cost of Capital 

On February 7, 2017, SCE, Pacific Gas and Electric Company, SDG&E, and SoCalGas (collectively, the “Investor-Owned 
Utilities”), ORA and TURN jointly filed a petition to modify the prior CPUC decisions addressing the Investor-Owned 
Utilities' costs of capital. The requested modifications would extend the next cost of capital application filing deadline two 
years to April 22, 2019 for the year 2020; reset SCE's authorized cost of long-term debt and preferred stock in 2018; and 
reduce SCE's authorized ROE. Subject to the CPUC's approval of the petition for modification, SCE's authorized ROE will 
be reduced from the current 10.45% to 10.30% beginning on January 1, 2018. The updated cost of capital and corresponding 
revenue requirement impact will be submitted to the CPUC in September 2017, to be effective January 1, 2018. While the 
actual changes to SCE's revenue requirement resulting from the petition for modification will not be known until SCE's filing 
in September 2017, SCE estimates that its annual revenue requirement will be reduced by approximately $66 million 
(approximately $39 million after-tax), beginning in 2018. Changes in market interest rates can have material effects on the 
cost of SCE’s future financings and consequently on the estimated change in annual revenue requirements. 

The petition for modification provides that SCE's long-term debt, preferred stock and common equity costs will be reset for 
the year 2018 and will then remain unchanged until December 31, 2019 unless they are changed by the operation of the cost 
of capital adjustment mechanism. SCE’s current ratemaking capital structure (48% common equity, 43% long-term debt, and 
9% preferred equity) will remain unchanged and the cost of capital adjustment mechanism would not operate in 2017 but 
could operate in 2018 to change the cost of capital for 2019. If the mechanism is activated for 2019, SCE’s new 10.30% ROE 
will be adjusted according to the existing terms of the mechanism. 

Energy Efficiency Incentive Mechanism

In December 2016, the CPUC awarded SCE incentives of approximately $18 million, approximately 75% of the requested 
award, for Part 2 of the 2014 program year and Part 1 of the 2015 program year savings. There is no assurance that the CPUC 
will make an award for any given year.

FERC Formula Rates 

In November 2016, SCE filed its 2017 annual update with the FERC with the rates effective from January 1, 2017 to 
December 31, 2017. The update provided support for an increase in SCE's transmission revenue requirement of $97 million 
or 9% over amounts currently authorized in rates. The increase is mainly due to the completion of several major transmission 
projects in 2015 and to recover prior undercollections. FERC has approved SCE's formula or methodology for setting 
transmission rates under its jurisdiction through 2017. SCE is required to file a replacement rate methodology by November 
2017, to be effective January 2018.

Long Beach Service Interruptions 

In July 2015, SCE's customers who are served via the network portion of SCE's electric system in Long Beach, California 
experienced service interruptions due to multiple underground vault fires and underground cable failures. No personal 
injuries were reported in connection with these events. SCE expects to incur penalties as a result of these events. Although 
resolution will be subject to settlement discussions with SED and CPUC review and approval, SCE has recorded a liability 
for the estimated loss.

RESULTS OF OPERATIONS

SCE

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 revenues 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

2016 vs 2015 

Earning activities were primarily affected by the following:

•  Higher operating revenue of $199 million is primarily due to:

•  An increase in revenue of approximately $191 million related to the increase in authorized revenue from the escalation 

mechanism set forth in the 2015 GRC decision. 

•  An increase in FERC-related revenue of $68 million primarily related to higher operating costs including amortization 
of the regulatory asset associated with the Coolwater-Lugo transmission project and rate base growth partially offset 
by a $15 million increase in 2015 due to a change in estimate under the FERC formula rate mechanism. 

•  An increase in revenue of $25 million ($15 million after-tax) related to the incremental return on the pole loading rate 

base recorded through the pole loading balancing account. 

•  An increase of $46 million primarily due to tax benefits recognized in 2015 related to net operating loss carrybacks for 

San Onofre decommissioning costs resulting in a reduction in revenue in 2015 (offset in income taxes). 

•  A decrease in revenue of $52 million for incremental tax benefits refunded to customers. In 2016, SCE recorded a 
revenue refund to customers of $133 million for 2012 – 2014 incremental tax benefits related to repair deductions 
(offset in income taxes as discussed below). This revenue refund resulted from the CPUC's approval of SCE's request 
to refund incremental tax repair deductions that were not addressed in SCE's 2015 GRC decision. Partially offsetting 

9

the refund of 2012 – 2014 incremental tax repair deductions, SCE recognized $81 million lower incremental tax 
repairs and other benefits refunded to customers through balancing accounts in 2016. 

•  Energy efficiency incentive awards were $18 million in 2016 compared to $29 million in 2015. In addition, in 2016, 
the CPUC approved a settlement agreement in which SCE agreed to refund $13 million related to incentive awards 
SCE received for savings achieved by its 2006 – 2008 energy efficiency programs. 

•  SCE's portion of NEIL insurance and legal cost recoveries of approximately $20 million in 2015 arising from the 

outage and shutdown of the San Onofre Units 2 and 3 generating stations.

•  A decrease of $29 million for other operating revenue resulting from lower contributions received from customers due 

to the retroactive extension of bonus depreciation in the PATH Act of 2015.

•  Lower operation and maintenance expense of $38 million primarily due to lower labor related to SCE's focus on 
operational and service excellence as well as lower outside services partially offset by higher transmission and 
distribution costs for rain and storm-related activities.

•  Higher depreciation, decommissioning and amortization expense of $83 million primarily related to depreciation on 
higher rate base and amortization of the regulatory asset related to the Coolwater-Lugo plant, as discussed above.

•  Higher property and other taxes of $17 million primarily due to higher property assessed values in 2016.

•  Higher interest expense of $15 million primarily due to reduced interest capitalization (AFUDC debt) related to lower 

construction work in progress balances and a higher interest rate on balancing account overcollections in 2016.

•  Higher other income and expenses of $15 million primarily due to higher insurance benefits and lower advertising 
expense in 2016. See "Notes to Consolidated Financial Statements—Note 14. Interest and Other Income and Other 
Expenses" for further information.

•  Lower income taxes of $251 million primarily due to the following:

•  Write-down of $382 million in 2015 of regulatory assets previously recorded for recovery of deferred income taxes 

from 2012 – 2014 incremental tax repair deductions. 

•  Higher income tax benefits in 2016 of $31 million primarily due to $79 million related to the flow-through of 
incremental tax benefits for 2012 – 2014 to customers partially offset by lower income tax benefits in 2016 of 
$48 million related to the flow-through of incremental tax repair and other benefits refunded to customers through 
balancing accounts. 

•  Lower income tax expense in 2016 of $13 million related to the adoption of the FASB guidance on accounting for 

share-based payments (see "Notes to Consolidated Financial Statements—Note 1. Summary of Significant Accounting 
Guidance—New Accounting Guidance" for further information).

•  A change in liabilities related to uncertain tax positions related to repair deductions, which resulted in income tax 
benefits of $100 million during the second quarter of 2015. See "—Income Taxes" below for more information. 

•  Higher pre-tax income in 2016, as discussed above.

•  Higher preferred and preference stock dividends of $10 million primarily related to new issuances in 2016 and late 2015 

partially offset by redemptions of preferred stock.

2015 vs 2014 

Earning activities were primarily affected by the following:

•  Lower operating revenue of $526 million is primarily due to:

•  A decrease in authorized CPUC revenue of $379 million (excludes amounts classified as cost-recovery activities). The 
decrease in revenue is primarily due to lower authorized revenue for operation and maintenance expenses and for 
flow-through items for income tax benefits related to repair and cost of removal deductions. 

•  A decrease in revenue from approximately $300 million of tax benefits in excess of amounts authorized in the 2015 
GRC and recognized through the TAMA and the pole loading balancing account (offset in income tax benefits 

10

discussed below). In addition, SCE recorded $39 million ($26 million after-tax) of incremental return on the pole 
loading rate base recorded through this balancing account. 

•  An increase in FERC-related revenue of $83 million primarily related to rate base growth and higher operating costs. 

•  An increase in San Onofre-related revenue of $40 million due to the implementation of the San Onofre OII Settlement 
Agreement. Revenue for San Onofre for 2015 primarily related to recovery of amortization of the regulatory asset and 
authorized return as provided by the San Onofre Settlement Agreement compared to revenue in 2014 related to 
recovery of San Onofre's cost of service.

•  Energy efficiency incentive awards were $29 million in 2015 compared to $22 million in 2014.

•  SCE's portion of NEIL insurance and legal cost recoveries of approximately $20 million in 2015 (See "Notes to the 

Consolidated Financial Statements—Note 11. Commitments and Contingencies—Contingencies—San Onofre Related 
Matters" for further information on the agreement with NEIL).

•  Higher revenue in 2014 from approval by the CPUC of a $30 million increase in the 2012 – 2014 authorized revenue 

requirement related to deferred income taxes and from $15 million of generator settlements. See “Notes to the 
Consolidated Financial Statements—Note 10. Regulatory Assets and Liabilities—Net Regulatory Balancing 
Accounts.”

•  Lower operation and maintenance expense of $129 million primarily due to: 

•  Lower San Onofre-related expense of $93 million. During 2014, San Onofre-related expenses were recorded as 

operation and maintenance expenses. During 2015, the CPUC authorized SCE reimbursement of 2014 costs from the 
nuclear decommissioning trusts with such reimbursement subsequently refunded to customers. During 2015, 
decommissioning expenses were reimbursed from the nuclear decommissioning trust and, therefore, did not result in 
operation and maintenance expenses. 

•  A decrease of $77 million primarily related to transmission and distribution, legal, and customer service costs partially 

offset by higher outside service costs in 2015.

•  Higher severance costs related to workforce reduction efforts ($26 million in 2015 and $2 million in 2014). 

• 

In 2015, SCE incurred a penalty of approximately $17 million related to not reporting certain ex parte communications 
on a timely basis.

•  Higher depreciation, decommissioning and amortization expense of $195 million primarily due to San Onofre-related 

expense of $134 million in 2015 related to the amortization of the regulatory asset and a $61 million increase in 
depreciation primarily related to transmission and distribution investments. 

•  Higher property and other taxes of $16 million primarily due to an increase in assessed property values in 2015.

• 

Impairment and other charges of $163 million ($72 million after-tax) in 2014 related to the San Onofre OII Settlement 
Agreement, as discussed below.

•  Higher other income and expenses of $21 million primarily due to higher AFUDC equity income related to a higher rate 
and higher construction work in progress balances in 2015 and a $15 million penalty recorded in 2014 resulting from the 
San Bernardino and San Gabriel settlements. These increases were offset by $10 million of lower insurance benefits in 
2015 and a $7 million of sales tax refund related to San Onofre received in 2014. See "Notes to Consolidated Financial 
Statements—Note 14. Interest and Other Income and Other Expenses" for further information.

•  Higher income taxes of $33 million primarily due to the following:

•  Write-down of $382 million in 2015 of regulatory assets previously recorded for recovery of deferred income taxes 

from 2012 – 2014 incremental tax repair deductions. 

•  An increase in income tax benefits in 2015 primarily related to $263 million (after-tax) of repair deductions (offset in 
operating revenue above) for TAMA and pole loading balancing account partially offset by lower tax benefits on other 
property-related items in 2015.

•  A change in liabilities related to uncertain tax positions related to repair deductions, which resulted in income tax 

benefits of $100 million and $29 million during the second quarters of 2015 and 2014, respectively. See "—Income 
Taxes" below for more information.

•  Lower pre-tax income in 2015, as discussed above, partially offset by the impact of the San Onofre OII Settlement 

Agreement. 

Cost-Recovery Activities

2016 vs 2015

Cost-recovery activities were primarily affected by the following:

•  Higher purchased power and fuel of $261 million primarily due to the NEIL insurance recoveries received in 2015 

(discussed below) and a change in portfolio mix partially offset by lower load related to cooler weather. 

In October 2015, San Onofre owners reached an agreement with NEIL to resolve all insurance claims arising out of the 
failures of the San Onofre replacement steam generators. SCE customer's portion of amounts recovered from NEIL has 
been distributed to SCE customers via a credit to SCE's ERRA account of approximately $300 million in 2015. 

•  Lower operation and maintenance expense of $115 million primarily due to lower transmission access charges and lower 
spending on various public purpose programs partially offset by an increase in transmission and distribution costs for 
drought related activities.

2015 vs 2014

Cost-recovery activities were primarily affected by the following:

•  Lower purchased power and fuel of $1.3 billion primarily driven by lower power and gas prices, the NEIL insurance 
recoveries and the CAISO generation surcharge of $83 million in 2014 (as discussed below). These decreases were 
partially offset by higher realized losses on economic hedging activities ($148 million in 2015 compared to $57 million in 
2014). Fuel costs were $176 million in 2015 and $256 million in 2014.

During 2014, the CAISO issued invoices implementing a FERC order which revised FERC tariffs for costs associated 
with scheduling coordinator activities. The impact of implementing the order and revised invoices resulted in a 
transmission refund of $106 million reflected in operation and maintenance expense and a generation surcharge of 
$83 million reflected in purchased power expense. These transactions did not impact earnings as the net refund was 
provided to customers through a FERC balancing account mechanism.

•  Lower operation and maintenance expense of $38 million primarily due to lower spending on various public purpose 

programs, lower pension and benefit expenses and a decrease in transmission access charges, partially offset by the 2014 
CAISO refund of $106 million as discussed above.

Supplemental Operating Revenue Information

SCE's retail billed and unbilled revenue (excluding wholesale sales and balancing account over/undercollections) was 
$10.7 billion in 2016 and $12.2 billion for both 2015 and 2014. 

The 2016 revenue reflects:

•  A decrease of $1.15 billion primarily due to the implementations of the 2016 ERRA rate decrease and the 2015 GRC 

decision in January 2016.

•  A sales volume decrease of $321 million due to lower load requirements related to cooler weather experienced in 2016 

compared to 2015.

The 2015 revenue reflects:

•  An increase of $160 million primarily due to the implementations of the 2014 ERRA rate increase in June 2014 and the 

San Onofre-related rate adjustment in January 2015.

•  A sales volume decrease of $169 million due to lower load requirements related to cooler weather experienced in 2015 

compared to 2014. 

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").

Income Taxes

SCE’s income tax provision decreased by $251 million in 2016 compared to 2015 and increased by $33 million in 2015 
compared to 2014. The effective tax rates were 14.6%, 31.3% and 23.2% for 2016, 2015 and 2014, respectively. SCE's 
effective tax rate is below the federal statutory rate of 35% 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 in 2016 was primarily due to the 
$382 million write-down in 2015 of regulatory assets (discussed in "Management Overview—Highlights of Operating 
Results") partially offset by revisions in liabilities related to uncertain tax positions in 2015. The effective tax rate increase in 
2015 was primarily due to a $382 million write-down in 2015 of regulatory assets and income tax benefits in 2014 related to 
San Onofre OII Settlement Agreement, partially offset by higher income tax benefits related to tax repair deductions (as 
discussed above) and the change in liabilities related to uncertain tax positions.

See "Notes to Consolidated Financial Statements—Note 7. Income Taxes" for a reconciliation of the federal statutory rate of 
35% to the effective income tax rates and "Management Overview—Permanent Retirement of San Onofre" above for more 
information.

1     Includes income of $5 million, $9 million and $2 million in 2016, 2015, 2014 related to losses (net of distributions) allocated to tax 

equity investors under the HLBV accounting method.

2     Includes interest expense (pre-tax) of $37 million, $31 million and $25 million in 2016, 2015, and 2014, respectively.

3   

Includes income tax benefits of $15 million in 2016 related to the adoption of an accounting standard for share-based payments. See 
"Notes to Consolidated Financial Statements—Note 1" for further information.

The loss from continuing operations of Edison International Parent and Other increased $64 million in 2016 compared to 
2015 primarily due to:

•  An increase in losses of Edison Energy Group of $32 million, including a $13 million after-tax charge during 2016 from a 
buy-out of an earn-out provision contained in one of the 2015 acquisitions, higher operating and development expenses 
and lower revenue and gross margin from the sale of solar systems in 2016 compared to 2015. The results for the twelve 
months ended December 31, 2016 include the three businesses acquired by Edison Energy in December 2015 and 
expanded sales and support personnel. Revenue for the Edison Energy Group was $42 million and $34 million for the 
twelve months ended December 31, 2016 and 2015, respectively. 

•  A decrease in income from Edison Mission Group and subsidiaries of $32 million in 2016 primarily due to income related 
to affordable housing projects in 2015. In December 2015, EMG's subsidiary, Edison Capital, completed the sale of its 
remaining affordable housing investment portfolio which represents the exit of this business activity. 

13

The loss from continuing operations of Edison International Parent and Other decreased $13 million in 2015 compared to 
2014 primarily due to:

•

An increase in losses of Edison Energy Group primarily due to higher operating expenses for 2015. The change was
partially offset by an increase in income allocated to subsidiaries of Edison Energy Group under the HLBV accounting
method that resulted in losses allocated to tax equity investors. For further information, see "Management Overview—
Highlights of Operating Results."

•

In December 2015, EMG's subsidiary, Edison Capital, completed the sale of its remaining affordable housing investment
portfolio which represents the exit of this business activity. Earnings from Edison Capital were $30 million and
$34 million for 2015 and 2014, respectively.

• A decrease in the loss from corporate expenses and other primarily due to income tax benefits and lower corporate

expenses during 2015.

Income from Discontinued Operations (Net of Tax)

Income from discontinued operations, net of tax, was $12 million, $35 million and $185 million for the years ended 
December 31, 2016, 2015 and 2014, respectively. The 2016 and 2015 income were primarily related to the resolution of tax 
issues related to EME. The 2015 income also included insurance recoveries. The 2014 income was related to the impact of 
completing the transactions called for in the EME Settlement Agreement and income tax benefits from resolution of uncertain 
tax positions and other impacts related to EME. 

LIQUIDITY AND CAPITAL RESOURCES

SCE

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

In the next 12 months, SCE expects to fund its obligations, capital expenditures and dividends through operating cash flows, 
tax benefits and capital market financings of debt and preferred equity, as needed. SCE also has availability under its credit 
facilities to fund cash requirements.

Available Liquidity

At December 31, 2016, SCE had $1.89 billion available under its $2.75 billion credit facility. For further details see "Notes to 
Consolidated Financial Statements—Note 5. Debt and Credit Agreements." SCE may finance balancing account 
undercollections and working capital requirements to support operations and capital expenditures with commercial paper or 
other borrowings, subject to availability in the capital markets.

Debt Covenant

The 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 
December 31, 2016, SCE's debt to total capitalization ratio was 0.43 to 1.

At December 31, 2016, SCE was in compliance with all other financial covenants that affect access to capital.

1       Direct expenditures include direct labor, land and contract costs incurred for the respective projects and exclude overhead    

costs that are included in the capital expenditures forecasted for remaining investment.

West of Devers

The West of Devers Project consists of upgrading and reconfiguring approximately 48 miles of existing 220 kV transmission 
lines between the Devers, El Casco, Vista and San Bernardino substations, increasing the power transfer capabilities in 
support of California's renewable portfolio standards goals. 

In August 2016, the CPUC approved the construction of the West of Devers Project. As a result of the delay in receipt of the 
Project's approval from the CPUC, SCE has deferred the timing of project capital expenditures. ORA filed an Application for 
Rehearing in September 2016 stating that the August 2016 decision failed to follow the California Environmental Quality Act 
when it approved the Project and should have approved the alternative project with the amended scope. SCE does not know 
when the CPUC will issue a decision on the Application for Rehearing. There is no stay of activities pending determination of 
the Application for Rehearing and SCE is continuing to perform activities related to construction, such as environmental 
permitting and mitigation planning in order to achieve a 2021 in-service date. 

Mesa Substation 

The Mesa Substation Project consists of demolishing the existing 220 kV Mesa Substation and constructing a new 500 kV 
substation. The Mesa Substation project would address reliability concerns by providing additional transmission import 
capability, allowing greater flexibility in the siting of new generation, and reducing the total amount of new generation 
required to meet local reliability needs in the Western Los Angeles Basin area. In February 2017, the CPUC issued a final 
decision approving SCE's proposed project. Construction planning activities that had been delayed pending the CPUC's final 
decision have commenced. 

Alberhill System

The Alberhill System Project consists 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 2016, the CPUC issued a draft environmental impact report that identified an alternative substation site. 
The $397 million estimated cost for this project reflects the scope proposed by SCE. 

Riverside Transmission Reliability

The Riverside Transmission Reliability Project is a joint project between SCE and Riverside Public Utilities (RPU), the 
municipal utility department of the City of Riverside. While RPU would be responsible for constructing some of the Project's 
facilities within Riverside, SCE's portion of the Project consists of constructing upgrades to its system, including a new 230-
kV Substation; certain interconnection and telecommunication facilities and transmission lines in the cities 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 

15

was originally developed, SCE informed the CPUC in July 2016 that it supports a revised description of the Project. The 
CPUC continues to collect information regarding the revised Project in support of a supplemental environmental review. 
Potential revisions to the Project have not been reflected in the direct expenditures or scheduled in service date in the table 
above, however, revisions are likely to increase the total direct expenditures and delay the completion of the Project. 

Eldorado-Lugo-Mohave Upgrade

The Eldorado-Lugo-Mohave Upgrade Project will increase capacity on existing transmission lines to allow additional 
renewable energy to flow from Nevada to southern California. The Project would modify SCE’s existing Eldorado, Lugo, and 
Mohave electrical substations to accommodate the increased current flow from Nevada to southern California; increase the 
power flow through the existing 500 kV transmission lines by constructing two new capacitors along the lines; raise 
transmission tower heights to meet ground clearance requirements; and install communication wire on our transmission lines 
to allow for communication between existing SCE substations.

Tehachapi

The Tehachapi Project consists of new and upgraded electric transmission lines and substations between eastern Kern County 
and San Bernardino County and was undertaken to bring renewable resources in Kern County to energy consumers in the Los 
Angeles basin and the California energy grid. The project consists of eleven segments. Segments 1-3 were placed in service 
beginning in 2009 through 2013. Segments 4-11 were placed in service in December 2016. 

SCE filed a petition for modification with the CPUC in January 2017 to update the cost estimate for all elements of segments 
4-11 to $2.7 billion (2016 dollars) from $2.0 billion (2016 dollars) of CPUC-approved cost findings. The cost increase is 
based on several factors, including additional project scope, schedule delays and work stoppages due to regulatory activity, 
increased environmental activities, and higher costs than the historical data used for estimates. Many of the cost increases are 
due to external factors not contemplated when the initial cost estimates were developed and not accounted for in the CPUC's 
original cost findings, which had also reduced the amount of contingency significantly below SCE's original estimates. Cost 
recovery for nearly all transmission elements of the project is incorporated in the existing FERC rates, subject to FERC 
review and approval.

Coolwater-Lugo

In February 2016, SCE filed an abandoned plant recovery request at FERC for the costs of the cancelled Coolwater-Lugo 
transmission project pursuant to the authority granted by FERC for SCE to recover 100% of all prudently-incurred costs if 
the project is cancelled for reasons beyond SCE's control. The project was cancelled by the CPUC in 2015 due to a reduction 
in need. SCE requested recovery of the $37.1 million in costs that SCE incurred for the project over a twelve-month period 
through the FERC transmission formula rate. In December 2016, SCE reached a settlement under which it will recover 100% 
of the requested $37.1 million of costs incurred in return for certain additional procedural safeguards to be implemented in all 
future abandoned plant recovery requests. The period for parties to file any protests to the settlement has expired without any 
protests filed but the settlement remains subject to FERC approval. 

Decommissioning of San Onofre

The decommissioning of a nuclear plant requires the management of three related activities: radiological decommissioning, 
non-radiological decommissioning and the management of spent nuclear fuel. The decommissioning process is expected to 
take many years. Decommissioning of San Onofre Unit 1 began in 1999 and major decommissioning work was completed in 
2008, except for reactor vessel disposal and certain underground work that was deferred to allow for the construction of the 
San Onofre Independent Spent Fuel Storage Installation. The initial activity phase of radiological decommissioning of Units 
2 and 3 began in June 2013 with SCE filing a certification of permanent cessation of power operations at San Onofre with the 
NRC. SCE is currently permitted to start major radiological decommissioning activities pursuant to NRC regulations, 
provided SCE obtains all necessary environmental permits for decommissioning. SCE has engaged a decommissioning 
general contractor to undertake a significant scope of decommissioning activities for Units 1, 2 and 3 at San Onofre.

During the second quarter of 2014, SCE updated its decommissioning cost estimate based on a site specific assessment. The 
decommissioning cost estimate in 2014 dollars is $4.4 billion (SCE share is $3.3 billion) and includes costs from June 7, 
2013 through to the respective completion dates to decommission San Onofre Units 2 and 3 estimated to be in 2052. The 
decommissioning cost estimate is subject to a number of uncertainties including the cost of disposal of nuclear waste, cost of 
removal of property, site remediation costs as well as a number of other assumptions and estimates, including when the 
federal government may remove spent fuel canisters from the San Onofre site, as to which there can be no assurance. The 
cost estimate is subject to change and such changes may be material. For further information, see "Notes to Consolidated 
Financial Statements—Note 1. Summary of Significant Accounting Policies—Nuclear Decommissioning and Asset 

16

Retirement Obligations." The CPUC will conduct a reasonableness review for costs for each year. SCE's share of the 
decommissioning costs recorded during 2016 were $168 million and are subject to reasonableness review by the CPUC. 

SCE has nuclear decommissioning trust funds for San Onofre Units 2 and 3 of $2.8 billion as of December 31, 2016. If the 
decommissioning cost estimate and assumptions regarding trust performance do not change, SCE believes that future 
contributions to the trust funds will not be necessary. 

SCE Dividends

SCE made $701 million and $758 million in dividend payments to its parent, Edison International, in 2016 and 2015, 
respectively. The timing and amount of future dividends are dependent upon several factors including the level of capital 
expenditures, operating cash flows and earnings. See "Notes to Consolidated Financial Statements—Note 1. Summary of 
Significant Accounting Policies—SCE Dividend Restrictions" for discussion of dividend restrictions.

Margin and Collateral Deposits

Certain derivative instruments, power procurement contracts and other contractual arrangements contain collateral 
requirements. Future collateral requirements may differ from the requirements at December 31, 2016, due to the addition of 
incremental power and energy procurement contracts with collateral requirements, if any, and the impact of changes in 
wholesale power and natural gas prices on SCE's contractual obligations.

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

The table below provides the amount of collateral posted by SCE to its counterparties as well as the potential collateral that 
would be required as of December 31, 2016.

2 

Incremental collateral requirements were based on potential changes in SCE's forward positions as of December 31, 
2016 due to adverse market price movements over the remaining lives of the existing power procurement contracts 
using a 95% confidence level.

Regulatory Balancing Accounts

SCE's cash flows are affected by regulatory balancing accounts over- or under-collections. Over- and under-collections 
represent differences between cash collected in current rates for specified forecasted costs and the costs actually incurred. 
With some exceptions, SCE seeks to adjust rates on an annual basis or at other designated times to recover or refund the 
balances recorded in its balancing account. Under- or over-collections in these balancing accounts impact cash flows and can 
change rapidly. Over- and under-collections accrue interest based on a three-month commercial paper rate published by the 
Federal Reserve.

As of December 31, 2016, SCE had regulatory balancing account net overcollections of $1.7 billion, primarily consisting of 
overcollections related to the base rate revenue account and public purpose-related and energy efficiency program costs. 
Overcollections related to the base rate revenue account are expected to decrease as refunds are provided to customers during 
2017. Overcollections related to public purpose-related programs are expected to decrease as costs are incurred to fund 
programs established by the CPUC. See "Notes to Consolidated Financial Statements—Note 10. Regulatory Assets and 
Liabilities" for further information.

17

Edison International Parent and Other

Edison International Parent and Other's liquidity and its ability to pay operating expenses and pay dividends to common 
shareholders are dependent on dividends from SCE, realization of tax benefits and access to bank and capital markets. Edison 
International may also finance working capital requirements, payment of obligations and capital investments, including 
capital contributions to subsidiaries to fund new businesses, with commercial paper or other borrowings, subject to 
availability in the capital markets. 

At December 31, 2016, Edison International Parent had $712 million available under its $1.25 billion multi-year revolving 
credit facility. For further details, see "Notes to Consolidated Financial Statements—Note 5. Debt and Credit Agreements." 

The 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 0.65 to 1. At December 31, 2016, Edison International Parent's 
consolidated debt to total capitalization ratio was 0.47 to 1.

At December 31, 2016, Edison International Parent was in compliance with all financial covenants that affect access to 
capital.

Net Operating Loss and Tax Credit Carryforwards

Edison International has approximately $1,152 million of net operating loss and tax credit carryforwards at December 31, 
2016 (excluding $176 million of unrecognized tax benefits and $242 million of Capistrano Wind net operating loss and tax 
credit carryforwards) which are available to offset future consolidated taxable income or tax liabilities (see Note 7 for further 
information on taxes payable to Capistrano Wind). In December 2015, the PATH Act of 2015 extended 50% bonus 
depreciation for qualifying property retroactive to January 1, 2015 and through 2017 and provided for 40% bonus 
depreciation in 2018 and 30% in 2019. As a result, realization of these tax benefits has been deferred (currently forecasted to 
be realized through 2021). The timing of realization of these tax benefits may be further delayed in the event of other changes 
in tax regulations and the value of the net operating loss carryforwards could be permanently reduced if tax reform decreases 
the corporate tax rate.

Edison Energy Group Capital Expenditures

Forecasted capital expenditures for Edison Energy Group's commercial solar activities are estimated to be $114 million in 
2017. Edison Energy Group expects to finance a majority of these expenditures through project debt and tax equity 
financings. For further information, see "Notes to Consolidated Financial Statements—Note 9. Investments."

Includes the nuclear decommissioning trusts.

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

Net income and noncash items increased in 2016 by $265 million from 2015 and decreased in 2015 by $604 million from 
2014. The increase in 2016 was primarily due to higher authorized revenue in 2016 from the escalation mechanism set forth 
in the 2015 GRC decision. The decrease in 2015 was primarily due to the implementation of the 2015 GRC decision. The 
factors that impacted these items are discussed under "Results of Operations—SCE—Earning Activities." 

Net cash for working capital was $236 million, $16 million and $79 million in 2016, 2015 and 2014, respectively. The net 
cash for 2016 and 2015 was primarily related to timing of disbursements ($45 million in 2016 and $120 million in 2015) and 
timing of receipts from customers ($230 million in 2016 and $70 million in 2015). In addition, SCE had net tax payments of 
$78 million in 2016 and $144 million in 2015. The net cash in 2014 was primarily related to net tax refunds of $88 million 
due to net operating loss carrybacks to periods that SCE previously had taxable income. 

Net cash provided by regulatory assets and liabilities, including changes in over (under) collections of balancing accounts, 
was $(292) million, $1.7 billion and $(358) million in 2016, 2015 and 2014, 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:

2016

•  Lower cash due to a decrease in ERRA overcollections for fuel and purchased power of $419 million in 2016 primarily 
due to the implementation of the 2016 ERRA rate decrease in January 2016, partially offset by lower than forecasted 
power and gas prices experienced in 2016. 

•  The public purpose and energy efficiency programs track differences between amounts authorized by the CPUC and 

amounts incurred to fund programs established by the CPUC. Overcollections increased by $309 million in 2016 due to 
higher funding and lower spending for these programs.

•  SCE had a decrease in cash of approximately $182 million primarily due to a 2016 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.

19

2015

•  Higher cash due to a decrease in ERRA undercollections of $1.5 billion in 2015 primarily due to lower power and gas 

prices experienced in 2015, the 2015 application of 2013 and 2014 nuclear decommissioning costs refunds against ERRA 
undercollections and the NEIL settlement proceeds from insurance claims arising out of the failures of the San Onofre 
replacement steam generators. In January 2015, SCE reclassified the regulatory liability for generator settlements to 
ERRA to refund customers as required by the CPUC.

•  During 2015, BRRBA overcollections increased by $314 million primarily due to revenue previously collected from 

customers that was expected to be refunded as part of the 2015 GRC decision. 

•  Overcollections for the public purpose and energy efficiency programs decreased by $191 million in 2015 primarily due 
to higher spending for these programs. The decrease was partially offset by an increase in funding of the new system 
generation program for 2015.

•  The 2015 GRC Decision established a tax accounting memorandum account (referred to as "TAMA"). As a result of this 
memorandum account, together with a balancing account for pole loading expenditures, any differences between the 
forecasted tax repair deductions and actual tax repair deductions will be adjusted through customer rates. At December 31, 
2015, SCE had a regulatory liability of $248 million related to these accounts (impact of TAMA is offset in non-cash 
items above).

2014

•  During 2014, BRRBA overcollections decreased by $242 million primarily due to refunds to customers of approximately 
$150 million, related to the sale of Four Corners, an electric generating facility in which SCE held a 48% ownership 
interest, in December 2013. 

•  Overcollections for the public purpose and energy efficiency programs decreased by $278 million in 2014, respectively, 
primarily due to higher spending for these programs. The decrease was partially offset by an increase in funding of the 
new system generation program for 2014.

•  During 2014, ERRA undercollections increased by $23 million primarily due to the amount and price of power and fuel 

being higher than forecasted. The increase was partially offset by a $540 million reclassification from regulatory liabilities 
to ERRA for collection of GRC revenue in excess of cost of service related to San Onofre consistent with its advice filing 
in November 2014.

Cash flows (used in) provided by other noncurrent assets and liabilities were $(41) million, $(508) million and $33 million in 
2016, 2015 and 2014, respectively. Major factors affecting cash flow related to noncurrent assets and liabilities were 
activities related to SCE's nuclear decommissioning trusts (principally related to the payment of decommissioning costs). 
Decommissioning costs of San Onofre were approximately $168 million and $216 million in 2016 and 2015, respectively 
(such costs were recorded as a reduction of SCE's asset retirement obligation).

Cash flows used in investing activities are primarily due to capital expenditures and funding of nuclear decommissioning 
trusts. Capital expenditures were $3.6 billion for 2016, $4.2 billion for 2015 and $3.9 billion for 2014, primarily related to 
transmission, distribution and generation investments. The decrease in capital expenditures during 2016 was primarily due to 
lower FERC capital spending. Net proceeds (purchases) of nuclear decommissioning trust investments were $179 million, 
$374 million and $(44) million for 2016, 2015 and 2014, respectively. See "Nuclear Decommissioning Trusts" below for 
further discussion. The 2016 net proceeds from sale of nuclear decommissioning trust investments was used to fund 
decommissioning costs less net earnings during the period. The 2015 net proceeds from sale of nuclear decommissioning 
trust investments was used to fund 2013, 2014 and a portion of 2015 decommissioning costs less net earnings during the 
period. The 2014 net purchase of nuclear decommissioning trust investments was due to net earnings during the period. In 
addition, during the third quarter of 2016, SCE received proceeds of $140 million for a loan on the cash surrender value of 
life insurance policies. The proceeds were used for general corporate purposes.

Net cash (used in) provided by operating activities of the nuclear decommissioning trusts relate to interest and dividends less 
administrative expenses, taxes and decommissioning costs. See "Notes to Consolidated Financial Statements—Note 9. 
Investments" for further information. Such activities represent the source (use) of the funds for investing activities. The net 
cash impact represents the contributions made by SCE to the nuclear decommissioning trusts. During 2015, SCE made a 
contribution of $54 million to the non-qualified decommissioning trust related to tax benefits received and pursuant to a 
CPUC decision related to decommissioning costs for San Onofre Unit 1.

In future periods, decommissioning costs of San Onofre will increase significantly. Beginning in March 2016, funds for 
decommissioning costs are requested from the nuclear decommissioning trusts one month in advance. Decommissioning 
disbursements are funded from sales of investments of the nuclear decommissioning trusts. See "Notes to Consolidated 
Financial Statements—Note 9. Investments" for further information.

includes interest payments totaling $8.36 billion and $93 million over applicable period of the debt for SCE and Edison 
International Parent and Other, respectively.

2  Certain power purchase agreements entered into with independent power producers are treated as operating or capital leases. For 

further discussion, see "Notes to Consolidated Financial Statements—Note 11. Commitments and Contingencies."

3  At December 31, 2016, SCE's minimum other operating lease payments were primarily related to vehicles, office space and 
other equipment. For further discussion, see "Notes to Consolidated Financial Statements—Note 11. Commitments and 
Contingencies."

4  For additional details, see "Notes to Consolidated Financial Statements—Note 11. Commitments and Contingencies." At 

December 31, 2016, other commitments were primarily related to maintaining reliability and expanding SCE's transmission and 
distribution system and capacity reduction contracts.

5  At December 31, 2016, Edison International Parent and Other and SCE had estimated contributions to the pension and PBOP 

plans. SCE estimated contributions are $106 million, $106 million, $115 million, $157 million and $160 million in 2017, 2018, 
2019, 2020 and 2021, respectively, which are excluded from the table above. Edison International Parent and Other estimated 
contributions are $51 million, $18 million, $28 million, $26 million and $26 million for the same respective periods and are 
excluded from the table above. These amounts represent estimates that are based on assumptions that are subject to change. See 
"Notes to Consolidated Financial Statements—Note 8. Compensation and Benefit Plans" for further information.

6  At December 31, 2016, Edison International and SCE had a total net liability recorded for uncertain tax positions of 

$471 million and $371 million, respectively, which is excluded from the table. Edison International and SCE cannot make 
reliable estimates of the cash flows by period due to uncertainty surrounding the timing of resolving these open tax issues with 
the tax authorities.

7  The contractual obligations table does not include derivative obligations and asset retirement obligations, which are discussed in 

"Notes to Consolidated Financial Statements—Note 6. Derivative Instruments," and "—Note 1. Summary of Significant 
Accounting Policies" and "—Note 9. Investments," respectively.

Contingencies

SCE has contingencies related to San Onofre Related Matters, Long Beach Service Interruptions, Nuclear Insurance, Wildfire 
Insurance and Spent Nuclear Fuel, which are discussed in "Notes to Consolidated Financial Statements—Note 11. 
Commitments and Contingencies."

MARKET RISK EXPOSURES

Edison International's and SCE's primary market risks include fluctuations in interest rates, commodity prices and volumes, 
and counterparty credit. Derivative instruments are used to manage market risks including market risks of SCE's customers. 
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 6. Derivative Instruments" and "—Note 4. Fair Value Measurements."

Interest Rate Risk

Edison International and SCE are exposed to changes in interest rates primarily as a result of its financing, investing and 
borrowing activities used for liquidity purposes, and to fund business operations and capital investments. The nature and 
amount of Edison International and SCE's long-term and short-term debt can be expected to vary as a result of future business 
requirements, market conditions and other factors. Fluctuations in interest rates can affect earnings and cash flows. Changes 
in interest rates may impact SCE's authorized rate of return for the period beyond 2017, see "Business—SCE—Overview of 
Ratemaking Process" for further discussion. The following table summarizes the increase or decrease to the fair value of 
long-term debt including the current portion as of December 31, 2016, if the market interest rates were changed while leaving 
all other assumptions the same:

SCE and its customers are exposed to the risk of a change in the market price of natural gas, electric power and transmission 
congestion. SCE's hedging program is designed to reduce exposure to variability in market prices related to SCE's purchases 
and sales of electric power and natural gas. SCE expects recovery of its related hedging costs through the ERRA balancing 
account or CPUC-approved procurement plans, and as a result, exposure to commodity price is not expected to impact 
earnings, but may impact timing of cash flows. As part of this program, SCE enters into energy options, swaps, forward 
arrangements, tolling arrangements, and congestion revenue rights ("CRRs"). The transactions are pre-approved by the 
CPUC or executed in compliance with CPUC-approved procurement plans. 

Fair Value of Derivative Instruments

The fair value of derivative instruments is included in the consolidated balance sheets unless subject to an exception under 
the applicable accounting guidance. Realized gains and losses from derivative instruments are expected to be recovered from 
or refunded to customers through regulatory mechanisms and, accordingly, changes in SCE's fair value have no impact on 
earnings. SCE does not use hedge accounting for these transactions due to this regulatory accounting treatment. For further 
discussion on fair value measurements and the fair value hierarchy, see "Notes to Consolidated Financial Statements—Note 4. 
Fair Value Measurements."

24

The fair value of outstanding derivative instruments used to mitigate exposure to commodity price risk was a net liability of 
$1.1 billion and $1.2 billion at December 31, 2016 and 2015, respectively. The following table summarizes the increase or 
decrease to the fair values of the net liability of derivative instruments included in the consolidated balance sheets as of 
December 31, 2016, if the electricity prices or gas prices were changed while leaving all other assumptions constant:

For information related to credit risks, see "Notes to Consolidated Financial Statements—Note 6. Derivative Instruments."

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 December 31, 2016, the amount of balance sheet exposure as described above broken down by the credit ratings of 
SCE's counterparties, was as follows:

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

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.

CRITICAL ACCOUNTING ESTIMATES AND POLICIES

The accounting policies described below are considered critical to obtaining an understanding of Edison International and 
SCE's consolidated financial statements because their application requires the use of significant estimates and judgments by 
management in preparing the consolidated financial statements. Management estimates and judgments are inherently 
uncertain and may differ significantly from actual results achieved. Management considers an accounting estimate to be 
critical if the estimate requires significant assumptions and changes in the estimate or, the use of alternative estimates, could 
have a material impact on Edison International's results of operations or financial position. For more information on Edison 
International's accounting policies, see "Notes to Consolidated Financial Statements—Note 1. Summary of Significant 
Accounting Policies."

Rate Regulated Enterprises

Nature of Estimate Required.    SCE follows the accounting principles for rate-regulated enterprises which are required for 
entities whose rates are set by regulators at levels intended to recover the estimated costs of providing service, plus a return 
on net investment, or rate base. Regulators may also impose certain penalties or grant certain incentives. Due to timing and 
other differences in the collection of revenue, these principles allow a cost that would otherwise be charged as an expense by 
an unregulated entity to be capitalized as a regulatory asset if it is probable that such cost is recoverable through future rates; 
conversely the principles allow creation of a regulatory liability for amounts collected in rates to recover costs expected to be 
incurred in the future or amounts collected in excess of costs incurred and are refundable to customers.

25

 
 
 
In November 2014, the CPUC approved the San Onofre OII Settlement Agreement, which resolved the CPUC's investigation 
regarding the steam generator replacement project at San Onofre and the related outages and subsequent shutdown of San 
Onofre. In a December 2016 joint ruling, the Assigned Commissioner and the Assigned ALJ expressed concerns about the 
extent to which the failure to timely report ex parte communications had impacted the settlement negotiations and directed 
SCE to meet and confer with the other parties in the OII to consider changing the terms of the San Onofre OII Settlement 
Agreement. 

In November 2015, SCE received the 2015 GRC decision. As part of this decision, the CPUC adopted a rate base offset 
associated with forecasted tax repair deductions during 2012 – 2014. The 2015 rate base offset is $324 million and amortizes 
on a straight line basis over 27 years. As a result of the rate base offset included in the final decision, SCE recorded an after 
tax charge of $382 million during the fourth quarter of 2015 to write down the regulatory assets previously recorded for 
recovery of deferred income taxes related to 2012 – 2014 incremental tax repair deductions.

Key Assumptions and Approach Used.    SCE's management assesses at the end of each reporting period whether regulatory 
assets are probable of future recovery by considering factors such as the current regulatory environment, the issuance of rate 
orders on recovery of the specific or a similar incurred cost to SCE or other rate-regulated entities, and other factors that 
would indicate that the regulator will treat an incurred cost as allowable for ratemaking purposes. Using these factors, 
management has determined that existing regulatory assets and liabilities are probable of future recovery or settlement. This 
determination reflects the current regulatory climate and is subject to change in the future. SCE's judgment that the San 
Onofre Regulatory Asset recorded at December 31, 2016 is probable, though not certain, of recovery is based on SCE's 
knowledge of the facts and judgment in applying the relevant regulatory principles to the issue. Such judgment is subject to 
uncertainty, and regulatory principles and precedents are not necessarily binding and are capable of interpretation. SCE has 
recorded a regulatory asset to reflect the expected recoveries under the San Onofre OII Settlement Agreement. At 
December 31, 2016, $857 million remains to be collected. 

Effect if Different Assumptions Used.    Significant management judgment is required to evaluate the anticipated recovery of 
regulatory assets, the recognition of incentives and revenue subject to refund, as well as the anticipated cost of regulatory 
liabilities or penalties. If future recovery of costs ceases to be probable, all or part of the regulatory assets and liabilities 
would have to be written off against current period earnings. At December 31, 2016, the consolidated balance sheets included 
regulatory assets of $7.8 billion and regulatory liabilities of $6.5 billion. If different judgments were reached on recovery of 
costs and timing of income recognition, SCE's earnings may vary from the amounts reported.

Income Taxes

Nature of Estimates Required.    As part of the process of preparing its consolidated financial statements, Edison International 
and SCE are required to estimate income taxes for each jurisdiction in which they operate. This process involves estimating 
actual current period tax expense together with assessing temporary differences resulting from differing treatment of items, 
such as depreciation, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are 
included within Edison International and SCE's consolidated balance sheets, including net operating loss and tax credit 
carryforwards that can be used to reduce liabilities in future periods.

Edison International and SCE take certain tax positions they believe are in accordance with the applicable tax laws. However, 
these tax positions are subject to interpretation by the IRS, state tax authorities and the courts. Edison International and SCE 
determine uncertain tax positions in accordance with the authoritative guidance.

Key Assumptions and Approach Used.    Accounting for tax obligations requires management judgment. Edison International 
and SCE's management use judgment in determining whether the evidence indicates it is more likely than not, based solely 
on the technical merits, that a tax position will be sustained, and to determine the amount of tax benefits to be recognized. 
Judgment is also used in determining the likelihood a tax position will be settled and possible settlement outcomes. In 
assessing uncertain tax positions Edison International and SCE consider, among others, the following factors: the facts and 
circumstances of the position, regulations, rulings, and case law, opinions or views of legal counsel and other advisers, and 
the experience gained from similar tax positions. Edison International and SCE's management evaluates uncertain tax 
positions at the end of each reporting period and makes adjustments when warranted based on changes in fact or law.

26

Effect if Different Assumptions Used.    Actual income taxes may differ from the estimated amounts which could have a 
significant impact on the liabilities, revenue and expenses recorded in the financial statements. Edison International and SCE 
continue to be under audit or subject to audit for multiple years in various jurisdictions. Significant judgment is required to 
determine the tax treatment of particular tax positions that involve interpretations of complex tax laws. Such liabilities are 
based on judgment and a final determination could take many years from the time the liability is recorded. Furthermore, 
settlement of tax positions included in open tax years may be resolved by compromises of tax positions based on current 
factors and business considerations that may result in material adjustments to income taxes previously estimated. 

Nuclear Decommissioning – Asset Retirement Obligation

Key Assumptions and Approach Used.    The liability to decommission SCE's nuclear power facilities is based on 
decommissioning studies performed in 2013 for Palo Verde and in 2014 for San Onofre Units 1, 2 and 3. See "Liquidity and 
Capital Resources—SCE—Decommissioning of San Onofre" for further discussion of the plans for decommissioning of San 
Onofre. SCE estimates that it will spend approximately $6.3 billion through 2079 to decommission its nuclear facilities. San 
Onofre Units 1, 2 and 3 decommissioning cost estimates are updated in each Nuclear Decommissioning Triennial Proceeding. 
Palo Verde decommissioning cost estimates are updated every three years by the operating agent, Arizona Public Services. 

The current ARO estimates for San Onofre and Palo Verde are based on the assumptions from these decommissioning 
studies:

•  Decommissioning Costs. The estimated costs for labor, "material, equipment and other," and low-level radioactive waste 

costs are included in each of the NRC decommissioning stages; license termination, site restoration, and spent fuel 
storage.

•  Escalation Rates. Annual escalation rates are used to convert the decommissioning cost estimates in base year dollars to 
decommissioning cost estimates in future-year dollars. Escalation rates are primarily used for labor, material, equipment, 
and low level radioactive waste burial costs. SCE's current estimates are based upon SCE's decommissioning cost 
methodology used for ratemaking purposes. Average escalation rates range from 1.7% to 7.5% (depending on the cost 
element) annually.

•  Timing. Cost estimates for Palo Verde are based on an assumption that decommissioning will commence promptly after 
the current NRC operating licenses expire. The Palo Verde 1, 2, 3 operating licenses currently expire in 2045, 2046 and 
2047 respectively. San Onofre Unit 1 started decommissioning in 1998 and Units 2 and 3 began in 2013. Cost estimates 
for San Onofre Units are currently based on completion of decommissioning activities by 2052. 

•  Spent Fuel Dry Storage Costs. Cost estimates are based on an assumption that the DOE will begin to take spent fuel in 

2024, and will remove the last spent fuel from the San Onofre and Palo Verde sites by 2051 and 2075, respectively. Costs 
for spent fuel monitoring are included until 2051 and 2075, respectively.

•  Changes in Decommissioning Technology, Regulation, and Economics. The current cost studies assume the use of current 

technologies under current regulations and at current cost levels. 

Effect if Different Assumptions Used.   The ARO for decommissioning SCE's nuclear facilities was $2.5 billion as of 
December 31, 2016, based on decommissioning studies performed in 2013 for Palo Verde and in 2014 for San Onofre Units 
1, 2 and 3. Changes in the estimated costs, execution strategy or timing of decommissioning, or in the assumptions and 
judgments by management underlying these estimates, could cause material revisions to the estimated total cost to 
decommission these facilities which could have a material effect on the recorded liability. The ARO for decommissioning San 
Onofre Units 2 & 3 is expected to be updated after onboarding the decommissioning general contractor and the subsequent 
development of a new decommissioning cost estimate during 2017.

The following table illustrates the increase to the ARO liability if the cost escalation rate was adjusted while leaving all other 
assumptions constant:

(in millions)

The increase in the ARO liability driven by an increase in the escalation rate would result in a decrease in the regulatory 
liability for recoveries in excess of ARO liabilities.

Pensions and Postretirement Benefits Other than Pensions ("PBOP(s)")

Nature of Estimate Required.    Authoritative accounting guidance requires companies to recognize the overfunded or 
underfunded status of defined benefit pension and other postretirement plans as assets and liabilities in the balance sheet; the 
assets and/or liabilities are normally offset through other comprehensive income (loss). In accordance with authoritative 
guidance for rate-regulated enterprises, regulatory assets and liabilities are recorded instead of charges and credits to other 
comprehensive income (loss) for its postretirement benefit plans that are recoverable in utility rates. Edison International and 
SCE have a fiscal year-end measurement date for all of its postretirement plans.

Key Assumptions of Approach Used.    Pension and other postretirement obligations and the related effects on results of 
operations are calculated using actuarial models. Two critical assumptions, discount rate and expected return on assets, are 
important elements of plan expense, and the discount rate is important to liability measurement. Additionally, health care cost 
trend rates are critical assumptions for postretirement health care plans. These critical assumptions are evaluated at least 
annually. Other assumptions, which require management judgment, such as rate of compensation increases and rates of 
retirement and turnover, are evaluated periodically and updated to reflect actual experience.

As of December 31, 2016, Edison International's and SCE's pension plans had a $4.3 billion and $3.8 billion benefit 
obligation, respectively, and total 2016 expense for these plans was $101 million and $93 million, respectively. As of 
December 31, 2016, the benefit obligation for both Edison International's and SCE's PBOP plans were $2.3 billion, and total 
2016 expense for Edison International's and SCE's plans was $20 million and $19 million, respectively. Annual contributions 
made to most of SCE's pension plans are currently recovered through CPUC-approved regulatory mechanisms and are 
expected to be, at a minimum, equal to the related annual expense.

Pension expense is recorded for SCE based on the amount funded to the trusts, as calculated using an actuarial method 
required for ratemaking purposes, in which the impact of market volatility on plan assets is recognized in earnings on a more 
gradual basis. Any difference between pension expense calculated in accordance with ratemaking methods and pension 
expense calculated in accordance with authoritative accounting guidance for pension is accumulated as a regulatory asset or 
liability, and is expected, over time, to be recovered from or returned to customers. As of December 31, 2016, this cumulative 
difference amounted to a regulatory asset of $95 million, meaning that the accounting method has recognized more in 
expense than the ratemaking method since implementation of authoritative guidance for employers' accounting for pensions 
in 1987.

Edison International and SCE used the following critical assumptions to determine expense for pension and other 
postretirement benefit for 2016:

*  Not applicable to pension plans.
1  The discount rate enables Edison International and SCE to state expected future cash flows at a present 

value on the measurement date. Edison International and SCE select its discount rate by performing a yield
curve analysis. This analysis determines the equivalent discount rate on projected cash flows, matching the
timing and amount of expected benefit payments. The AON-Hewitt yield curve is considered in
determining the discount rate.

2  To determine the expected long-term rate of return on pension plan assets, current and expected asset 

allocations are considered, as well as historical and expected returns on plan assets. A portion of PBOP 
trusts asset returns are subject to taxation, so the 5.6% rate of return on plan assets above is determined on
an after-tax basis. Actual time-weighted, annualized returns on the pension plan assets were 8.5%, 9.7%
and 5.8% for the one-year, five-year and ten-year periods ended December 31, 2016, respectively. Actual
time-weighted, annualized returns on the PBOP plan assets were 7.0%, 9.5% and 5.0% over these same
periods. Accounting principles provide that differences between expected and actual returns are recognized
over the average future service of employees.

3  The health care cost trend rate gradually declines to 5.0% for 2022 and beyond.

28

As of December 31, 2016, Edison International and SCE had unrecognized pension costs of $666 million and $598 million, 
and unrecognized PBOP costs of $140 million and $136 million, respectively. The unrecognized pension and PBOP costs 
primarily consisted of the cumulative impact of the reduced discount rates on the respective benefit obligations and the 
cumulative difference between the expected and actual rate of return on plan assets. Of these deferred costs, $479 million of 
SCE's pension costs and $33 million of SCE's PBOP costs are recorded as regulatory assets and is expected to be recovered 
over the average expected future service of employees.

Edison International's and SCE's pension and PBOP plans are subject to limits established for federal tax deductibility. SCE 
funds its pension and PBOP plans in accordance with amounts allowed by the CPUC. Executive pension plans have no plan 
assets.

Effect if Different Assumptions Used.    Changes in the estimated costs or timing of pension and other postretirement benefit 
obligations, or the assumptions and judgments used by management underlying these estimates, could have a material effect 
on the recorded expenses and liabilities. 

The following table summarizes the increase or (decrease) to projected benefit obligation for pension and the accumulated 
benefit obligation for PBOP if the discount rate were changed while leaving all other assumptions constant:

A one percentage point increase in the expected rate of return on pension plan assets would decrease Edison International's 
and SCE's current year expense by $31 million and $29 million, respectively, and a one percentage point increase in the 
expected rate of return on PBOP plan assets would decrease both Edison International's and SCE's current year expense by 
$20 million.

Accounting for Contingencies

Nature of Estimates Required.    Edison International and SCE record loss contingencies when management determines that 
the outcome of future events is probable of occurring and when the amount of the loss can be reasonably estimated. Gain 
contingencies are recognized in the financial statements when they are realized.

Key Assumptions and Approach Used.    The determination of a reserve for a loss contingency is based on management 
judgment and estimates with respect to the likely outcome of the matter, including the analysis of different scenarios. 
Liabilities are recorded or adjusted when events or circumstances cause these judgments or estimates to change. In assessing 
whether a loss is a reasonable possibility, Edison International and SCE may consider the following factors, among others: 
the nature of the litigation, claim or assessment, available information, opinions or views of legal counsel and other advisors, 
and the experience gained from similar cases. Edison International and SCE provide disclosures for material contingencies 
when there is a reasonable possibility that a loss or an additional loss may be incurred. 

Effect if Different Assumptions Used.    Actual amounts realized upon settlement of contingencies may be different than 
amounts recorded and disclosed and could have a significant impact on the liabilities, revenue and expenses recorded on the 
consolidated financial statements. For a discussion of contingencies, guarantees and indemnities, see "Notes to Consolidated 
Financial Statements—Note 11. Commitments and Contingencies."

NEW ACCOUNTING GUIDANCE

New accounting guidance is discussed in "Notes to Consolidated Financial Statements—Note 1. Summary of Significant 
Accounting Policies—New Accounting Guidance."

RISK FACTORS

RISKS RELATING TO EDISON INTERNATIONAL

Edison International's liquidity depends on SCE's ability to pay dividends and tax allocation payments to Edison 
International, monetization of tax benefits retained by EME, ability to borrow funds, and access to capital markets.

Edison International is a holding company and, as such, it has no operations of its own. Edison International's ability to meet 
its financial obligations, make investments, and to pay dividends on its common stock is primarily dependent on the earnings 
and cash flows of SCE and its ability to make upstream distributions. Prior to paying dividends to Edison International, SCE 
has financial and regulatory obligations that must be satisfied, including, among others, debt service and preferred stock 
dividends. In addition, CPUC holding company rules require that SCE's dividend policy be established by SCE's Board of 
Directors on the same basis as if SCE were a stand-alone utility company, and that the capital requirements of SCE, as 
deemed to be necessary to meet SCE's electricity service obligations, shall receive first priority from the Boards of Directors 
of both Edison International and SCE. SCE may also owe tax-allocation payments to Edison International under applicable 
tax-allocation agreements. Access to capital markets may be impacted by economic conditions that have an adverse effect on 
Edison International's liquidity. See "Risks Relating to Southern California Edison Company" below for further discussion.

The Edison International consolidated tax group retains significant net operating loss and tax credit carryforwards.  
Realization of such tax benefits may be delayed or permanently reduced by future tax legislation that extends bonus 
depreciation or reduces the current corporate tax rate.

Edison International's business activities are concentrated in one industry and in one region.

Edison International business activities are concentrated in the electricity industry. Its principal subsidiary, SCE, serves 
customers only in southern and central California. Although Edison International, through Edison Energy Group, is 
developing competitive businesses that are diversified geographically, these businesses are not material. As a result, Edison 
International's future performance may be affected by events and economic factors unique to California or by regional 
regulation or legislation.

Edison International is developing businesses held by Edison Energy Group that may not be successful.

Edison International, through Edison Energy Group, is developing businesses to capitalize on changes in the electricity 
industry. Edison International intends to invest in companies to develop the capabilities of the Edison Energy Group entities 
but there can be no assurance that these entities will be profitable.

RISKS RELATING TO SOUTHERN CALIFORNIA EDISON COMPANY

Regulatory Risks

SCE is subject to extensive regulation and the risk of adverse regulatory decisions and changes in applicable regulations 
or legislation.

SCE operates in a highly regulated environment. SCE's business is subject to extensive federal, state and local energy, 
environmental and other laws and regulations. Among other things, the CPUC regulates SCE's retail rates and capital 
structure, and the FERC regulates SCE's wholesale rates. The NRC regulates the decommissioning of San Onofre. The 
construction, planning, and siting of SCE's power plants and transmission lines in California are also subject to regulation by 
the CPUC and other local, state and federal agencies.

SCE must periodically apply for licenses and permits from these various regulatory authorities and abide by their respective 
orders. Should SCE be unsuccessful in obtaining necessary licenses or permits or should these regulatory authorities initiate 
any investigations or enforcement actions or impose penalties or disallowances on SCE, SCE's business could be materially 
affected. The process of obtaining licenses and permits from regulatory authorities may be delayed or defeated by opponents 
and such delay or defeat could have a material effect on SCE's business.

30

In September 2016, the California Governor signed into law several CPUC reform bills that establish rules governing, among 
other subjects, communications between the CPUC officials, staff and the regulated utilities. Changes to the rules and 
processes around ex parte communications could result in delayed decisions, increased investigations, enforcement actions 
and penalties. In addition, the CPUC or other parties may initiate investigations of past communications between public 
utilities, including SCE, and CPUC officials and staff that could result in reopening completed proceedings for 
reconsideration.

In addition, existing regulations may be revised or reinterpreted and new laws and regulations may be adopted or become 
applicable to SCE, or its facilities or operations, in a manner that may have a detrimental effect on SCE's business or result in 
significant additional costs. In addition, regulations adopted via the public initiative or legislative process may apply to SCE, 
or its facilities or operations, in a manner that may have a detrimental effect on SCE's business or result in significant 
additional costs.

SCE's financial results depend upon its ability to recover its costs and to earn a reasonable rate of return on capital 
investments in a timely manner from its customers through regulated rates.

SCE's ongoing financial results depend on its ability to recover its costs from its customers, including the costs of electricity 
purchased for its customers, through the rates it charges its customers as approved by the CPUC and FERC. SCE's financial 
results also depend on its ability to earn a reasonable return on capital, including long-term debt and equity. SCE's ability to 
recover its costs and earn a reasonable rate of return can be affected by many factors, including the time lag between when 
costs are incurred and when those costs are recovered in customers' rates and differences between the forecast or authorized 
costs embedded in rates (which are set on a prospective basis) and the amount of actual costs incurred. The CPUC or the 
FERC may not allow SCE to recover costs on the basis that such costs were not reasonably or prudently incurred or for other 
reasons. Further, SCE may be required to incur expenses before the relevant regulatory agency approves the recovery of such 
costs. For example, the recovery of the Tehachapi transmission project costs are subject to FERC approval and the public 
need for the project is reviewed by the CPUC. SCE filed a petition for modification with the CPUC in January 2017 to update 
the cost estimate for all elements of segments 4-11 to $2.7 billion (2016 dollars) from $2.0 billion (2016 dollars) of CPUC-
approved cost findings. For further information, see "Liquidity and Capital Resources—SCE—Capital Investment Plan—
Tehachapi" in the MD&A.

Changes in laws and regulations or changes in the political and regulatory environment also may have an adverse effect on 
the SCE's ability to timely recover its costs and earn its authorized rate of return. In addition, SCE may be required to incur 
costs to comply with new state laws or to implement new state policies before SCE is assured of cost recovery.

SCE's capital investment plan, increasing procurement of renewable power and energy storage, increasing environmental 
regulations, leveling demand, and the cumulative impact of other public policy requirements, collectively place continuing 
upward pressure on customer rates. If SCE is unable to obtain a sufficient rate increase or modify its rate design to recover its 
costs (including an adequate return on capital) in rates in a timely manner, its financial condition and results of operations 
could be materially affected. For further information on SCE's rate requests, see "Management Overview—Regulatory 
Proceedings—2018 General Rate Case" and "—FERC Formula Rates" in the MD&A.

SCE's energy procurement activities are subject to regulatory and market risks that could materially affect its financial 
condition and liquidity.

SCE obtains energy, capacity, environmental credits and ancillary services needed to serve its customers from its own 
generating plants and through contracts with energy producers and sellers. California law and CPUC decisions allow SCE to 
recover, through the rates it is allowed to charge its customers, reasonable procurement costs incurred in compliance with an 
approved procurement plan. Nonetheless, SCE's cash flows remain subject to volatility primarily resulting from changes in 
commodity prices. For instance, natural gas prices have increased due to the closure of the SoCalGas underground gas 
storage facility in Aliso Canyon, California. Additionally, significant and prolonged gas use restrictions may adversely impact 
the reliability of the electric grid if critical generation resources are limited in their operations. For further information, see 
"Business—SCE—Purchased Power and Fuel Supply." SCE is also subject to the risks of unfavorable or untimely CPUC 
decisions about the compliance with SCE's procurement plan and the reasonableness of certain procurement-related costs.

SCE may not be able to hedge its risk for commodities on economic terms or fully recover the costs of hedges through the 
rates it is allowed to charge its customers, which could materially affect SCE's liquidity and results of operations, see "Market 
Risk Exposures" in the MD&A.

31

Financing Risks

As a capital intensive company, SCE relies on access to the capital markets. If SCE were unable to access the capital 
markets or the cost of financing were to substantially increase, its liquidity and operations could be materially affected.

SCE regularly accesses the capital markets to finance its activities and is expected to do so by its regulators as part of its 
obligation to serve as a regulated utility. SCE's needs for capital for its ongoing infrastructure investment program are 
substantial. SCE's ability to obtain financing, as well as its ability to refinance debt and make scheduled payments of 
principal, interest and preferred stock dividends, are dependent on numerous factors, including SCE's levels of indebtedness, 
maintenance of acceptable credit ratings, financial performance, liquidity and cash flow, and other market conditions. SCE's 
inability to obtain additional capital from time to time could have a material effect on SCE's liquidity and operations.

Competitive and Market Risks

The electricity industry is undergoing change, including increased competition, technological advancements, and political 
and regulatory developments

California utilities are experiencing increasing deployment by customers and third parties of DERs, such as solar generation, 
energy storage, energy efficiency and demand response technologies. This growth will require modernization of the electric 
distribution grid to, among other things, accommodate two-way flows of electricity and increase the grid's capacity to 
interconnect DERs. To this end, the CPUC is conducting proceedings to: evaluate changes to the planning and operation of 
the electric distribution grid in order to prepare for higher penetration of DERs; consider future grid modernization and grid 
reinforcement investments; evaluate if traditional grid investments can be deferred by DERs, and if feasible, what, if any, 
compensation to utilities would be appropriate; and clarify the role of the electric distribution grid operator. The outcome of 
these proceedings is unknown. These changes could materially affect SCE's business model and its financial condition and 
results of operations. For more information, see "Management Overview—Capital Program—Distribution Grid 
Development" in the MD&A.

Customer-owned generation and community choice aggregators each reduce the amount of electricity customers purchase 
from utilities and have the effect of increasing utility rates unless customer rates are designed to allocate the costs of the 
distribution grid across all customers that benefit from its use. For example, customers in California that generate their own 
power do not currently pay all transmission and distribution charges and non-bypassable charges, subject to limitations, 
which result in increased utility rates for those customers who do not own their generation. Such increases influence the 
public discussion regarding changes in the electric utility business model.

In addition, the FERC has opened transmission development to competition from independent developers, allowing such 
developers to compete with incumbent utilities for the construction and operation of transmission facilities. For more 
information, see "Business—SCE—Competition."

Operating Risks

SCE's financial condition and results of operations could be materially affected if it is unable to successfully manage the 
risks inherent in operating and maintaining its facilities.

SCE's infrastructure is aging and could pose a risk to system reliability. In order to mitigate this risk, SCE is engaged in a 
significant and ongoing infrastructure investment program. This substantial investment program elevates operational risks 
and the need for superior execution in SCE's activities. SCE's financial condition and results of operations could be materially 
affected if it is unable to successfully manage these risks as well as the risks inherent in operating and maintaining its 
facilities, the operation of which can be hazardous. SCE's inherent operating risks include such matters as the risks of human 
performance, workforce capabilities, public opposition to infrastructure projects, delays, environmental mitigation costs, 
difficulty in estimating costs or in recovering costs that are above original estimates, system limitations and degradation, and 
interruptions in necessary supplies.

32

Weather-related incidents and other natural disasters could materially affect SCE's financial condition and results of 
operations.

Weather-related incidents and other natural disasters, including storms, wildfires and earthquakes, can disrupt the generation 
and transmission of electricity, and can seriously damage the infrastructure necessary to deliver power to SCE's customers. 
These events can lead to lost revenues and increased expenses, including higher maintenance and repair costs. They can also 
result in regulatory penalties and disallowances, particularly if SCE encounters difficulties in restoring power to its customers 
on a timely basis. These occurrences could materially affect SCE's business, financial condition and results of operations, and 
the inability to restore power to SCE's customers could also materially damage the business reputation of SCE and Edison 
International.

The generation, transmission and distribution of electricity are dangerous and involve inherent risks of damage to private 
property and injury to employees and the general public.

Electricity is dangerous for employees and the general public should they come in contact with electrical current or 
equipment, including through downed power lines or if equipment malfunctions. Injuries and property damage caused by 
such events can subject SCE to liability that, despite the existence of insurance coverage, can be significant. No assurance 
can be given that future losses will not exceed the limits of SCE's or its contractors' insurance coverage. The CPUC has 
increased its focus on public safety with an emphasis on heightened compliance with construction and operating standards 
and the potential for penalties being imposed on utilities. Additionally, the CPUC has delegated to its staff the authority to 
issue citations to electric utilities, which can impose fines of up to $50,000 per violation per day, pursuant to the CPUC's 
jurisdiction for violations of safety rules found in statutes, regulations, and the CPUC's General Orders. Such penalties and 
liabilities could be significant and materially affect SCE's liquidity and results of operations.

There are inherent risks associated with owning and decommissioning nuclear power generating facilities and obtaining 
cost reimbursement, including, among other things, costs exceeding estimates, execution risks, potential harmful effects 
on the environment and human health and the danger of storage, handling and disposal of radioactive materials. Existing 
insurance and ratemaking arrangements may not protect SCE fully against losses from a nuclear incident. 

SCE expects to fund decommissioning costs with assets that are currently held in nuclear decommissioning trusts. SCE 
believes that the nuclear decommissioning trusts' assets will be sufficient to pay the estimated costs of decommissioning 
without further contributions but the costs ultimately incurred could exceed the current estimates. The costs of 
decommissioning San Onofre are subject to reasonableness reviews by the CPUC. These costs may not be recoverable 
through regulatory processes or otherwise unless SCE can establish that the costs were reasonably incurred. In addition, SCE 
faces inherent execution risks including such matters as the risks of human performance, workforce capabilities, public 
opposition, permitting delays, and governmental approvals.

Despite the fact that San Onofre is being decommissioned, the presence of spent nuclear fuel still poses a potential risk of a 
nuclear incident. Federal law limits public liability claims from a nuclear incident to the amount of available financial 
protection, which is currently approximately $13.4 billion. SCE and other owners of San Onofre and Palo Verde have 
purchased the maximum private primary insurance available of $450 million per site. If nuclear incident liability claims were 
to exceed $450 million, the remaining amount would be made up from contributions of approximately $13.0 billion made by 
all of the nuclear facility owners in the U.S., up to an aggregate total of $13.4 billion. There is no assurance that the CPUC 
would allow SCE to recover the required contribution made in the case of one or more nuclear incident claims that exceeded 
$450 million. If this public liability limit of $13.4 billion is insufficient, federal law contemplates that additional funds may 
be appropriated by Congress. There can be no assurance of SCE's ability to recover uninsured costs in the event the additional 
federal appropriations are insufficient. For more information on nuclear insurance risk, see "Notes to Consolidated Financial 
Statements—Note 11. Commitments and Contingencies—Contingencies—Nuclear Insurance."

SCE's insurance coverage for wildfires arising from its ordinary operations may not be sufficient.

Edison International has experienced increased costs and difficulties in obtaining insurance coverage for wildfires that could 
arise from SCE's ordinary operations. Edison International, SCE or its contractors may experience coverage reductions and/or 
increased wildfire insurance costs in future years. No assurance can be given that future losses will not exceed the limits of 
SCE's or its contractors' insurance coverage. Uninsured losses and increases in the cost of insurance may not be recoverable 
in customer rates. A loss which is not fully insured or cannot be recovered in customer rates could materially affect Edison 
International's and SCE's financial condition and results of operations. For more information on wildfire insurance risk, see 
"Notes to Consolidated Financial Statements—Note 11. Commitments and Contingencies—Contingencies—Wildfire 
Insurance."

33

Cybersecurity and Physical Security Risks

SCE's systems and network infrastructure may be vulnerable to physical and cyber attacks, intrusions or other 
catastrophic events that could result in their failure or reduced functionality.

Regulators, such as the NERC, and U.S. Government Departments, including the Departments of Defense, Homeland 
Security and Energy, have noted that threat sources continue to seek to exploit potential vulnerabilities in the U.S. national 
electric grid and other energy infrastructures and that such attacks and disruptions, both physical and cyber, are becoming 
increasingly sophisticated and dynamic. As SCE moves from an analog to a digital electric grid, new cyber security risks may 
arise. An example of such new risks is the installation of "smart" meters in SCE's service territory. This technology may 
represent a new route for attacks on SCE's information systems. SCE's operations require the continuous availability of 
critical information technology systems and network infrastructure. SCE's systems have been, and will likely continue to be, 
subjected to computer attacks of malicious codes, unauthorized access attempts, and other illicit activities, but to date, SCE 
has not experienced a material cyber security breach. Although SCE actively monitors developments in this area and is 
involved in various industry groups and government initiatives, no security measures can completely shield such systems and 
infrastructure from vulnerabilities to cyber attacks, intrusions or other catastrophic events that could result in their failure or 
reduced functionality. If SCE's information technology systems security measures were to be breached or a critical system 
failure were to occur without timely recovery, SCE could be unable to fulfill critical business functions such as delivery of 
electricity to customers and/or sensitive confidential personal and other data could be compromised, which could result in 
violations of applicable privacy and other laws, financial loss to SCE or to its customers, loss of confidence in SCE's security 
measures, customer dissatisfaction, and significant litigation exposure, all of which could materially affect SCE's financial 
condition and results of operations and materially damage the business reputation of Edison International and SCE. 

Environmental Risks

SCE is subject to extensive environmental regulations that may involve significant and increasing costs and materially 
affect SCE.

SCE is subject to extensive environmental regulations and permitting requirements that involve significant and increasing 
costs and substantial uncertainty. SCE devotes significant resources to environmental monitoring, pollution control 
equipment, mitigation projects, and emission allowances to comply with existing and anticipated environmental regulatory 
requirements. Environmental regulations and permitting requirements also affect the cost and timing of transmission and 
distribution projects. At the state level, the current trend is toward more stringent standards, stricter regulation, higher 
reductions of GHG emissions, and more expansive application of environmental regulations. The adoption of laws and 
regulations to implement greenhouse gas controls could materially affect operations of power plants, which could in turn 
impact electricity markets and SCE's customer rates. SCE may also be exposed to risks arising from past, current or future 
contamination at its former or existing facilities or with respect to offsite waste disposal sites that have been used in its 
operations. Current and future California laws and regulations also increase the required amount of energy that must be 
procured from renewable resources. See "Business—Environmental Regulation of Edison International and Subsidiaries" for 
further discussion of environmental regulations under which SCE operates.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Information responding to this section is included in the MD&A under the heading "Market Risk Exposures."

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

34

Report of Independent Registered Public Accounting Firm

To the Board of Directors and 
Shareholders of Edison International

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, 
comprehensive income, changes in equity and cash flows present fairly, in all material respects, the financial position of 
Edison International and its subsidiaries at December 31, 2016 and 2015, and the results of their operations and their cash 
flows for each of the three years in the period ended December 31, 2016 in conformity with accounting principles generally 
accepted in the United States of America. In addition, in our opinion, the financial statement schedules listed in the index 
appearing under Item 15(a)(2) present fairly, in all material respects, the information set forth therein when read in 
conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal 
Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO). The Company's management is responsible for these financial statements and financial statement schedules, for 
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control 
over financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 
9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedules, and on the 
Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance 
with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan 
and perform the audits to obtain reasonable assurance about whether the financial statements are free of material 
misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our 
audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the 
financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating 
the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an 
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and 
evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included 
performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a 
reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures 
that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to 
permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and
Shareholders of Southern California Edison Company

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, 
comprehensive income, changes in equity and cash flows present fairly, in all material respects, the financial position of 
Southern California Edison Company and its subsidiaries as of December 31, 2016 and 2015, and the results of their 
operations and their cash flows for each of the three years in the period ended December 31, 2016 in conformity with 
accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement 
schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth 
therein when read in conjunction with the related consolidated financial statements. These financial statements and financial 
statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these 
financial statements and financial statement schedule based on our audits. We conducted our audits of these financial 
statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those 
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements 
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the financial statements, assessing the accounting principles used and significant estimates made by 
management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable 
basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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"). 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 International is also the parent company of Edison Energy Group, a holding 
company for subsidiaries engaged in pursuing competitive business opportunities across energy services and distributed solar 
for commercial and industrial customers. Such 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 International Parent and Other refer to Edison International 
Parent and its nonutility 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 accounting policies conform to accounting principles generally accepted in the United States 
of America, including the accounting principles for rate-regulated enterprises, which reflect the ratemaking policies of the 
California Public Utility Commission ("CPUC") and the Federal Energy Regulatory Commission ("FERC"). SCE applies 
authoritative guidance for rate-regulated enterprises to the portion of its operations in which regulators set rates at levels 
intended to recover the estimated costs of providing service, plus a return on net investments in assets, or rate base. 
Regulators may also impose certain penalties or grant certain incentives. Due to timing and other differences in the collection 
of electric utility revenue, these principles require an incurred cost that would otherwise be charged to expense by a 
non-regulated entity to be capitalized as a regulatory asset if it is probable that the cost is recoverable through future rates; 
and conversely the principles require recording of a regulatory liability for amounts collected in rates to recover costs 
expected to be incurred in the future or amounts collected in excess of costs incurred and refundable to customers. SCE 
assesses, at the end of each reporting period, whether regulatory assets are probable of future recovery. See Note 10 for 
composition of regulatory assets and liabilities.

The preparation of financial statements in conformity with United States generally accepted accounting principles ("GAAP") 
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and 
expenses during the reported period. Actual results could differ from those estimates. 

Cash Equivalents

Cash equivalents includes 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:

Allowance for Uncollectible Accounts

Allowances for uncollectible accounts are provided based upon a variety of factors, including historical amounts written-off, 
current economic conditions and assessment of customer collectability.

Inventory

SCE's inventory is primarily composed of materials, supplies and spare parts, and generally stated at average cost. 

Emission Allowances

SCE is allocated greenhouse gas ("GHG") allowances annually which it is then required to sell into quarterly auctions. GHG 
proceeds from the auctions are recorded as a regulatory liability to be refunded to customers. SCE purchases GHG 
allowances in quarterly auctions or from counterparties to satisfy its GHG emission compliance obligations and recovers such 
costs of GHG allowances from customers. GHG allowances held for use are classified as "Other current assets" on the 
consolidated balance sheets and are stated, similar to an inventory method, at the lower of weighted-average cost or market. 
SCE had GHG allowances of $113 million and $79 million at December 31, 2016 and 2015, respectively. GHG emission 
obligations were $95 million and $86 million at December 31, 2016 and 2015, respectively and are classified as "Other 
current liabilities" on the consolidated balance sheets.

Property, Plant and Equipment

SCE plant additions, including replacements and betterments, are capitalized. Direct material and labor and indirect costs 
such as construction overhead, administrative and general costs, pension and benefits, and property taxes are capitalized as 
part of plant additions. The CPUC authorizes a rate for each of the indirect costs which are allocated to each project based on 
either labor or total costs. 

Estimated useful lives (authorized by the CPUC) and weighted-average useful lives of SCE's property, plant and equipment, 
are as follows:

Generation plant
Distribution plant
Transmission plant
General plant and other

Estimated Useful Lives
10 years to 57 years
20 years to 60 years
40 years to 65 years
5 years to 60 years

Weighted-Average
Useful Lives
38 years
43 years
53 years
22 years

Depreciation of utility property, plant and equipment is computed on a straight-line, remaining-life basis. Depreciation 
expense was $1.52 billion, $1.42 billion and $1.33 billion for 2016, 2015 and 2014, respectively. Depreciation expense stated 
as a percent of average original cost of depreciable utility plant was, on a composite basis, 3.8%, 3.9% and 4.0% for 2016, 
2015 and 2014, respectively. Replaced or retired property costs are charged to accumulated depreciation. 

Nuclear fuel for the Palo Verde Nuclear Power Plant ("Palo Verde") is recorded as utility plant (nuclear fuel in the fabrication 
and installation phase is recorded as construction in progress) in accordance with CPUC ratemaking procedures. Nuclear fuel 
is amortized using the units of production method. 

AFUDC represents the estimated cost of debt and equity funds that finance utility-plant construction and is capitalized during 
certain plant construction. AFUDC is recovered in rates through depreciation expense over the useful life of the related asset. 
AFUDC equity represents a method to compensate SCE for the estimated cost of equity used to finance utility plant additions 
and is recorded as part of construction in progress. AFUDC equity was $74 million, $87 million and $65 million in 2016, 
2015 and 2014, respectively, and is reflected in "Interest and other income." AFUDC debt was $23 million, $31 million and 
$25 million in 2016, 2015 and 2014, respectively and is reflected as a reduction of "Interest expense."

Major Maintenance

Major maintenance costs for SCE's power plant facilities and equipment are expensed as incurred.

Impairment of Long-Lived Assets

Impairments of long-lived assets are evaluated based on a review of estimated future cash flows expected to be generated 
whenever events or changes in circumstances indicate that the carrying amount of such investments or assets may not be 

51

 
 
recoverable. If the carrying amount of a long-lived asset exceeds expected future cash flows, undiscounted and without 
interest charges, an impairment loss is recognized in the amount of the excess of fair value over the carrying amount. Fair 
value is determined via market, cost and income based valuation techniques, as appropriate. SCE's impaired assets are 
recorded as a regulatory asset if it is deemed probable that such amounts will be recovered from customers.

In 2014, the CPUC approved the San Onofre OII Settlement Agreement that SCE had entered into with a number of 
intervening parties. The San Onofre OII Settlement Agreement had resolved the CPUC's investigation regarding the Steam 
Generator Replacement Project at San Onofre and the related outages and subsequent shutdown of San Onofre. In 2014, SCE 
had recorded a pre-tax impairment charge of approximately $163 million (approximately $72 million after-tax). Including 
amounts previously recorded as an impairment charge in 2013, the total impact of the San Onofre OII Settlement Agreement 
was a pre-tax charge of $738 million (approximately $437 million after-tax). 

In a December 2016 joint ruling, the Assigned Commissioner and the Assigned ALJ directed SCE to meet and confer with the 
other parties in the OII to consider changing the terms of the San Onofre OII Settlement Agreement. See Note 11 for further 
information. 

Goodwill

Edison International assesses goodwill through annual goodwill impairment tests, at the reporting unit level, as of October 1st 
of each year. The fair value of the Edison Energy and SoCore Energy reporting units exceeded their carrying values at the 
date of the annual impairment analysis. As of December 31, 2016, goodwill is comprised of $78 million at the Edison Energy 
reporting unit and $22 million at the SoCore Energy reporting unit. Edison International will update these tests between 
annual tests if events occur or circumstances change such that it is more likely than not that the fair value of a reporting unit 
is below its carrying value.

Nuclear Decommissioning and Asset Retirement Obligations

The fair value of a liability for an asset retirement obligation ("ARO") is recorded in the period in which it is incurred, 
including a liability for the fair value of a conditional ARO, if the fair value can be reasonably estimated even though 
uncertainty exists about the timing and/or method of settlement. When an ARO liability is initially recorded, SCE capitalizes 
the cost by increasing the carrying amount of the related long-lived asset. For each subsequent period, the liability is 
increased for accretion expense and the capitalized cost is depreciated over the useful life of the related asset. 

AROs related to decommissioning of SCE's nuclear power facilities are based on site-specific studies conducted as part of 
each Nuclear Decommissioning Cost Triennial Proceeding ("NDCTP") conducted before the CPUC. Revisions of an ARO 
are established for updated site-specific decommissioning cost estimates. 

SCE adjusts its nuclear decommissioning obligation into a nuclear-related ARO regulatory asset and also records an ARO 
regulatory liability as a result of timing differences between the recognition of costs and the recovery of costs through the 
ratemaking process. For further discussion, see Notes 9 and 10.

SCE has not recorded an asset retirement obligation for assets that are expected to operate indefinitely or where SCE cannot 
estimate a settlement date (or range of potential settlement dates). As such, ARO liabilities are not recorded for certain 
retirement activities, including certain hydroelectric facilities.

The following table summarizes the changes in SCE's ARO liability, including San Onofre and Palo Verde:

account for the time value of money resulting from discounting.

The recorded liability to decommission SCE's nuclear power facilities (included in the table above) is $2.5 billion as of 
December 31, 2016. In 2016, SCE updated the recorded liability for Palo Verde and San Onofre Unit 1 based on the 2013 
decommissioning study performed for Palo Verde and the 2014 study for San Onofre Unit 1. The recorded liability for San 
Onofre Unit 2 and 3 is based on a 2014 decommissioning study which followed the decision to permanently retire San 
Onofre. The 2015 NDTCP filing is expected to be updated for San Onofre Units 2 and 3 after onboarding the 
decommissioning general contractor and the subsequent development of a new decommissioning cost estimate during 2017.

Decommissioning costs, which are recovered through customer rates over the term of each nuclear facility's operating 
license, are recorded as a component of depreciation expense, with a corresponding credit to the ARO regulatory liability. 
Amortization of the ARO asset (included within the unamortized nuclear investment) and accretion of the ARO liability are 
deferred as increases to the ARO regulatory liability account, resulting in no impact on earnings.

SCE has collected in rates amounts for the future costs of removal of its nuclear assets, and has placed those amounts in 
independent trusts. The cost of removal amounts, in excess of amounts collected for assets not legally required to be 
removed, are classified as regulatory liabilities.

Changes in the estimated costs, timing of decommissioning or the assumptions underlying these estimates could cause 
material revisions to the estimated total cost to decommission. SCE currently estimates that it will spend approximately 
$6.3 billion through 2079 to decommission its nuclear facilities. This estimate is based on SCE's decommissioning cost 
methodology used for ratemaking purposes, escalated at rates ranging from 1.7% to 7.5% (depending on the cost element) 
annually. These costs are expected to be funded from independent decommissioning trusts. SCE estimates annual after-tax 
earnings on the decommissioning funds of 2.4% to 4.1%. Future decommissioning costs related to SCE's nuclear assets are 
expected to be funded from independent decommissioning trusts. If the assumed return on trust assets is not earned or costs 
escalate at higher rates, SCE expects that additional funds needed for decommissioning will be recoverable through future 
rates. See Note 9 for further information. 

Due to regulatory recovery of SCE's nuclear decommissioning expense, prudently incurred costs for nuclear 
decommissioning activities do not affect SCE's earnings. SCE's nuclear decommissioning costs are subject to CPUC review 
through the triennial regulatory proceeding. SCE's nuclear decommissioning trust investments primarily consist of fixed 
income and equity investments that are classified as available-for-sale. Due to regulatory mechanisms, earnings and realized 
gains and losses (including other-than-temporary impairments) have no impact on electric utility revenue. Unrealized gains 
and losses on decommissioning trust funds increase or decrease the trust assets and the related regulatory asset or liability and 
have no impact on electric utility revenue or decommissioning expense. SCE reviews each security for other-than-temporary 
impairment on the last day of each month. If the fair value on the last day of two consecutive months is less than the cost for 
that security, SCE recognizes a loss for the other-than-temporary impairment. If the fair value is greater or less than the cost 
for that security at the time of sale, SCE recognizes a related realized gain or loss, respectively.

Deferred Financing Costs

Debt premium, discount and issuance expenses incurred in connection with obtaining financing are deferred and amortized 
on a straight-line basis. Under CPUC ratemaking procedures, SCE's debt reacquisition expenses are amortized over the 
remaining life of the reacquired debt or, if refinanced, the life of the new debt. SCE had unamortized losses on reacquired 
debt of $184 million and $201 million at December 31, 2016 and 2015, respectively, reflected as long-term "Regulatory 
assets" in the consolidated balance sheets. Edison International and SCE had unamortized debt issuance costs of $10 million 
and $7 million at December 31, 2016, respectively, and $11 million and $7 million at December 31, 2015, respectively, 
reflected in "Other long-term assets" on the consolidated balance sheets. In addition, Edison International and SCE had debt 
issuance costs of $81 million and $71 million at December 31, 2016, respectively, and $81 million and $77 million at 
December 31, 2015, respectively, reflected as a reduction of "Long-term debt" on the consolidated balance sheets. 

Amortization of deferred financing costs charged to interest expense is as follows:

Revenue Recognition

Revenue is recognized when electricity is delivered and includes amounts for services rendered but unbilled at the end of 
each reporting period and reflected in "Operating revenue" on the consolidated statements of income. Rates charged to 
customers are based on CPUC- and FERC-authorized revenue requirements. CPUC rates are implemented subsequent to final 
approval. 

CPUC 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. FERC rates also decouple revenue from volume of electricity sales. In November 2013, the FERC approved a 
formula rate effective January 1, 2012 to determine SCE's FERC transmission revenue requirement, including its construction 
work in progress ("CWIP") revenue requirement. Under operation of the formula rate, transmission revenue will be updated 
to actual cost of service annually. Differences between amounts collected and determined under the formula rate are either 
collected from or refunded to customers, and therefore, SCE earns revenue based on estimates of recorded rate base costs 
under the FERC formula rate.

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 and reflected in electric utility revenue and other operation and maintenance expense. SCE's franchise fees 
billed to customers and recorded as revenue were $111 million, $138 million and $134 million in 2016, 2015 and 2014, 
respectively. When SCE acts as an agent, 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.

Power Purchase Agreements

SCE enters into power purchase agreements in the normal course of business. A power purchase agreement may be 
considered a variable interest in a variable interest entity. Under this classification, the power purchase agreement is 
evaluated to determine if SCE is the primary beneficiary in the variable interest entity, in which case, such entity would be 
consolidated. None of SCE's power purchase agreements resulted in consolidation of a variable interest entity at 
December 31, 2016 and 2015. See Note 3 for further discussion of power purchase agreements that are considered variable 
interests.

A power purchase agreement may also contain a lease for accounting purposes. This generally occurs when a power purchase 
agreement (signed or modified after June 30, 2003) designates a specific power plant in which the buyer purchases 
substantially all of the output and does not otherwise meet a fixed price per unit of output exception. SCE has a number of 
power purchase agreements that contain leases. SCE's recognition of lease expense conforms to the ratemaking treatment for 
SCE's recovery of the cost of electricity and is recorded in purchased power. See Note 11 for further discussion of SCE's 
power purchase agreements, including agreements that are classified as operating and capital leases for accounting purposes.

A power purchase agreement that does not contain a lease may be classified as a derivative subject to a normal purchase and 
sale exception, in which case the power purchase agreement is classified as an executory contract and accounted for on an 
accrual basis. SCE purchases power under certain contracts that are not eligible for the normal purchase and sale exception 
and are recorded as a derivative on the consolidated balance sheets at fair value. Most of SCE's qualifying facilities ("QFs") 
contracts are not required to be recorded on the consolidated balance sheets because they either do not meet the definition of 
a derivative or meet the normal purchase and sale exception. See Note 6 for further information on derivative instruments.

Power purchase agreements that do not meet the above classifications are accounted for on an accrual basis.

Derivative Instruments

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 normal purchases and sales exception 
requires, among other things, physical delivery in quantities expected to be used or sold over a reasonable period in the 
normal course of business. Realized gains and losses from SCE's derivative instruments are expected to be recovered from or 
refunded to customers through regulatory mechanisms and, therefore, SCE's fair value changes have no impact on purchased-
power expense or earnings. SCE does not use hedge accounting for derivative transactions due to regulatory accounting 
treatment.

54

Where SCE's derivative instruments are subject to a master netting agreement and certain criteria are met, SCE presents its 
derivative assets and liabilities on a net basis on its consolidated balance sheets. In addition, derivative positions are offset 
against margin and cash collateral deposits. The results of derivative activities are recorded as part of cash flows from 
operating activities on the consolidated statements of cash flows. See Note 6 for further information on derivative 
instruments.

Leases

SCE enters into power purchase agreements that may contain leases, as discussed under "Power Purchase Agreements" 
above. SCE has also entered into a number of agreements to lease property and equipment in the normal course of business. 
Minimum lease payments under operating leases are levelized (total minimum lease payments divided by the number of 
years of the lease) and recorded as rent expense over the terms of the leases. Lease payments in excess of the minimum are 
recorded as rent expense in the year incurred.

Capital leases are reported as long-term obligations on the consolidated balance sheets in "Other deferred credits and other 
long-term liabilities." As a rate-regulated enterprise, SCE's capital lease amortization expense and interest expense are 
reflected in "Purchased power and fuel" on the consolidated statements of income.

Stock-Based Compensation

Stock options, performance shares, deferred stock units and restricted stock units have been granted under Edison 
International's long-term incentive compensation programs. Generally, Edison International does not issue new common 
stock for settlement of equity awards. Rather, a third party is used to purchase shares from the market and deliver such shares 
for the settlement of option exercises, performance shares, deferred stock units and restricted stock units. Performance shares 
awarded in 2014 that are earned are settled half in cash and half in common stock, while the performance shares awarded in 
2016 and 2015 that are earned are settled solely in cash. Deferred stock units and restricted stock units are settled in common 
stock; however, Edison International will substitute cash awards to the extent necessary to pay tax withholding or any 
government levies.

Stock-based compensation expense is recognized on a straight-line basis over the requisite service period. For awards granted 
to retirement-eligible participants stock compensation expenses are recognized on a prorated basis over the initial year or 
over the period between the date of grant and the date the participant first becomes eligible for retirement. Under new 
accounting guidance adopted in 2016, share-based payments may create a permanent difference between the amount of 
compensation expense recognized for book and tax purposes. The tax impact of this permanent difference is recognized in 
earnings in the period it is created.

SCE Dividend Restrictions

The CPUC regulates SCE's capital structure which limits the dividends it may pay Edison International. SCE may make 
distributions to Edison International as long as the common equity component of SCE's capital structure remains at or above 
48% on a 13-month weighted average basis. At December 31, 2016, SCE's 13-month weighted-average common equity 
component of total capitalization was 50.4% and the maximum additional dividend that SCE could pay to Edison 
International under this limitation was approximately $585 million, resulting in a restriction on net assets of approximately 
$13.9 billion.

55

Earnings Per Share

Edison International computes earnings per common share ("EPS") using the two-class method, which is an earnings 
allocation formula that determines EPS for each class of common stock and participating security. Edison International's 
participating securities are stock-based compensation awards payable in common shares, including performance shares and 
restricted stock units, which earn dividend equivalents on an equal basis with common shares once the awards are vested. 
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 
167,795, 2,046,045 and 125,345 shares of common stock for the years ended December 31, 2016, 2015 and 2014, 
respectively, were outstanding, but were not included in the computation of diluted earnings per share because the effect 
would have been antidilutive.

Income Taxes 

Edison International and SCE estimate their income taxes for each jurisdiction in which they operate. This involves 
estimating current period tax expense along with assessing temporary differences resulting from differing treatment of items 
(such as depreciation) for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which 
are included in the consolidated balance sheets. Income tax expense includes the current tax liability from operations and the 
change in deferred income taxes during the year. Investment tax credits are deferred and amortized to income tax expense 
over the lives of the properties or the term of the power purchase agreement of the respective project. 

Interest income, interest expense and penalties associated with income taxes are reflected in "Income tax expense" on the 
consolidated statements of income. 

Edison International's eligible subsidiaries are included in Edison International's consolidated federal income tax and 
combined state tax returns. Edison International has tax-allocation and payment agreements with certain of its subsidiaries. 
Pursuant to an income tax-allocation agreement approved by the CPUC, SCE's tax liability is computed as if it filed its 
federal and state income tax returns on a separate return basis.

Redeemable Noncontrolling Interest

Redeemable noncontrolling interest represents the portion of equity ownership in an entity that is not attributable to the 
equity holders of Edison International and which have rights to put their ownership back to a subsidiary of Edison 
International. Noncontrolling interest is initially recorded at fair value and is subsequently adjusted for income allocated to 
the noncontrolling interest and any distributions paid to the noncontrolling interest.

Certain solar projects for commercial customers are organized as limited liability companies and have noncontrolling equity 
investors (referred to as tax equity investors) which are entitled to allocations of earnings, tax attributes and cash flows in 
accordance with contractual agreements that vary over time. These entities are consolidated for financial reporting purposes 
but is not subject to income taxes as the taxable income (loss) and investment tax credits are allocated to the respective 
owners. The total consolidated assets and liabilities of these entities were $74 million and $23 million, respectively, at 
December 31, 2016 and were $82 million and $32 million, respectively, at December 31, 2015. Income (loss) of these entities 
are allocated to the noncontrolling interest based on the hypothetical liquidation at book value ("HLBV") accounting method. 
The HLBV accounting method is an approach that calculates the change in the claims of each member on the net assets of the 
investment at the beginning and end of each period. Each member’s claim is equal to the amount each party would receive or 
pay if the net assets of the investment were to liquidate at book value. Under the contract provisions, the tax equity investors' 
claim on net assets decreases rapidly in early years due to allocation of tax benefits resulting in additional non-operating 
income allocated to Edison International ($9 million and $16 million in 2016 and 2015, respectively). 

New Accounting Guidance

Accounting Guidance Adopted

In April 2015, the FASB issued an accounting standards update that requires debt issuance costs to be presented in the 
balance sheet as a direct reduction from the carrying amount of the related debt liability, consistent with debt discounts. 
Previously, accounting guidance required these costs to be presented as a deferred charge asset. Edison International and SCE 
adopted this guidance in the first quarter of 2016. At December 31, 2016, the amount of debt issuance costs that are reflected 
as a reduction of "Long-term debt" was $71 million for SCE and $81 million for Edison International. At December 31, 2015, 
the amount of debt issuance costs that have been reclassified from "Other long-term assets" to a reduction of "Long-term 
debt" was $77 million for SCE and $81 million for Edison International.

In April 2015, the FASB issued an accounting standards update on fees paid by a customer for software licenses. This new 
standard provides guidance about whether a cloud computing arrangement includes a software license which may be 
capitalized in certain circumstances. If a cloud computing arrangement does not include a software license, then the 
arrangement should be accounted for as a service contract. Edison International and SCE adopted this guidance prospectively, 
effective January 1, 2016. The adoption of this standard did not have a material impact on Edison International's and SCE's 
consolidated financial statements.

In May 2015, the FASB issued an accounting standards update which removes the requirement to categorize within the fair 
value hierarchy all investments for which fair value is measured using net asset value per share or its equivalent as a practical 
expedient. Edison International and SCE adopted in the fourth quarter of 2016. Certain prior year amounts have been 
retrospectively adjusted.

In March 2016, the FASB issued an accounting standards update to simplify the accounting for share-based payments. Under 
this new guidance, the tax effects related to share based payments are recorded through the income statement. Previously, tax 
benefits in excess of compensation cost ("windfalls") were recorded in equity, and tax deficiencies ("shortfalls") were 
recorded in equity to the extent of previous windfalls, and then to the income statement. In addition, as part of this new 
guidance an entity recognizes excess tax benefits regardless of whether the benefit reduces taxes payable in the current 
period, subject to normal valuation allowance considerations. Edison International and SCE adopted this guidance in the 
fourth quarter of 2016 using the modified retrospective approach, effective January 1, 2016. As a result, all excess tax 
benefits resulting from 2016 stock option exercises were reflected in the income statement. Income tax expense for Edison 
International and SCE was reduced by approximately $28 million and $13 million, respectively, for the year ended 
December 31, 2016. In addition, Edison International and SCE recorded an increase to beginning retained earnings for 
pre-2016 stock option exercises that had not been previously recorded in equity ($42 million and $6 million for Edison 
International and SCE, respectively). On a prospective basis, the excess tax benefits are classified as an operating activity 
along with other income tax cash flows on the statement of cash flows. Accruals of compensation costs are based on the 
number of awards that are expected to vest. Edison International and SCE made an accounting policy election to continue to 
estimate the number of awards that are expected to vest rather than account for forfeitures when they occur.

57

Accounting Guidance Not Yet Adopted 

In May 2014, the FASB issued an accounting standards update on revenue recognition including enhanced disclosures and 
further amended the standard in 2016. Under the new standard, revenue is recognized when (or as) a good or service is 
transferred to the customer and the customer obtains control of the good or service. This standard will be adopted on 
January 1, 2018. Edison International and SCE have completed the preliminary phases of their assessment of the impact on 
the consolidated financial statements and do not believe the adoption of this standard will have a material impact on the 
results of operations. Edison International and SCE anticipate adopting the standard using the modified retrospective 
application which means that Edison International and SCE would recognize the cumulative effect of initially applying the 
revenue standard as an adjustment to the opening balance of retained earnings in 2018.

In January 2016, the FASB issued an accounting standards update that amends the guidance on the classification and 
measurement of financial instruments. The amendments require equity investments (excluding those accounted for under the 
equity method or those that result in consolidation) to be measured at fair value, with changes in fair value recognized in net 
income. It also amends certain disclosure requirements associated with the fair value of financial instruments. In addition, the 
new guidance requires financial assets and financial liabilities to be presented separately in the notes to the financial 
statements, grouped by measurement category and form of financial asset. Edison International and SCE will adopt this 
guidance effective January 1, 2018. The adoption of this standard is not expected to have a material impact on Edison 
International's and SCE's consolidated financial statements.

In February 2016, the FASB issued an accounting standards update related to lease accounting including enhanced 
disclosures. Under the new standard, a lease is defined as a contract, or part of a contract, that conveys the right to control the 
use of identified assets for a period of time in exchange for consideration. Lessees will need to recognize leases on the 
balance sheet as a right-of-use asset and a related lease liability, and classify the leases as either operating or finance. The 
liability will be equal to the present value of lease payments. The asset will be based on the liability, subject to adjustment, 
such as for initial direct costs. Operating leases will result in straight-line expense while finance leases will result in a higher 
initial expense pattern due to the interest component. SCE, as a regulated entity, is permitted to continue to have straight-line 
expense for finance leases, assuming the rate recovery is based upon current payments. Lessees can elect to exclude from the 
balance sheet short-term contracts one year or less. This guidance is effective January 1, 2019. Early adoption is permitted, 
but Edison International and SCE do not expect to elect early adoption. The adoption of this standard is expected to increase 
right-of-use assets and lease liabilities in Edison International's and SCE's consolidated balance sheets. Edison International 
and SCE are currently evaluating the impact this standard will have on the results of operations and statements of cash flows. 

In June 2016, the FASB issued an accounting standards update to amend the guidance on the impairment of financial 
instruments. The new guidance adds an impairment model, known as the current expected credit loss model, which is based 
on expected losses rather than incurred losses. This guidance applies to most debt instruments, trade receivables, lease 
receivables, financial guarantee contracts, and loan commitments. This guidance is effective on January 1, 2020. Edison 
International and SCE are currently evaluating this new guidance.

In August and November 2016, the FASB issued accounting standards updates to amend the guidance on the presentation and 
classification of certain cash receipts and cash payments in the statement of cash flows to reduce diversity in practice. This 
guidance addresses eight specific cash flow classification issues, including debt prepayment or extinguishment costs, 
proceeds from the settlement of corporate-owned life insurance, distributions received from equity method investments and 
restricted cash. This standard also clarifies the application of the predominance principle where cash receipts and payments 
have aspects of more than one class of cash flows. The new standard is effective on January 1, 2018. Edison International and 
SCE are currently evaluating this new guidance.

In January 2017, the FASB issued an accounting standards update to simplify the accounting for goodwill impairment. This 
accounting standards update changes the procedural steps in applying the goodwill impairment test. A goodwill impairment 
will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of 
goodwill. Edison International will apply this guidance to the goodwill impairment test beginning in 2020.

Capitalized Software Costs

SCE capitalizes costs incurred during the application development stage of internal use software projects to property, plant, 
and equipment. SCE amortizes capitalized software costs ratably over the expected lives of the software, ranging from 5 to 
15 years and commencing upon operational use. Capitalized software costs, included in general plant and other above, were 
$1.4 billion at both December 31, 2016 and 2015 and accumulated amortization was $0.8 billion and $0.9 billion, at 
December 31, 2016 and 2015, respectively. Amortization expense for capitalized software was $249 million, $268 million 
and $271 million in 2016, 2015 and 2014, respectively. At December 31, 2016, amortization expense is estimated to be 
approximately $243 million annually for 2017 through 2021.

Note 3.  Variable Interest Entities

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

Variable Interest in VIEs that are not Consolidated

Power Purchase Contracts

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 QFs that contain variable pricing provisions 
based on the price of natural gas. SCE has concluded that it is not the primary beneficiary of these VIEs since it does not 
control the commercial and operating activities of these entities. 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 amounts due under the PPAs or the fair value of those derivative contracts. Under these 
contracts, SCE recovers the costs incurred through demonstration of compliance with its CPUC-approved long-term power 
procurement plans. SCE has no residual interest in the entities and has not provided or guaranteed any debt or equity support, 
liquidity arrangements, performance guarantees or other commitments associated with these contracts other than the purchase 
commitments described in Note 11. As a result, there is no significant potential exposure to loss to SCE from its variable 
interest in these VIEs. The aggregate contracted capacity dedicated to SCE from these VIE projects was 4,353 MW and 
4,062 MW at December 31, 2016 and 2015, respectively, and the amounts that SCE paid to these projects were $788 million 
and $640 million for the years ended December 31, 2016 and 2015, respectively. These amounts are recoverable in customer 
rates, subject to reasonableness review. 

Unconsolidated Trusts of SCE

SCE Trust I, Trust II, Trust III, Trust IV and Trust V were formed in 2012, 2013, 2014, 2015 and 2016 respectively, for the 
exclusive purpose of issuing the 5.625%, 5.10%, 5.75%, 5.375% and 5.45% trust preference securities, respectively ("trust 
securities"). The trusts are VIEs. SCE has concluded that it is not the primary beneficiary of these VIEs as it does not have 
the obligation to absorb the expected losses or the right to receive the expected residual returns of the trusts. SCE Trust I, 
Trust II, Trust III, Trust IV and Trust V issued to the public trust securities in the face amounts of $475 million, $400 million, 
$275 million, $325 million and $300 million (cumulative, liquidation amounts of $25 per share), respectively, and $10,000 of 
common stock each to SCE. The trusts invested the proceeds of these trust securities in Series F, Series G, Series H, Series J 
and Series K Preference Stock issued by SCE in the principal amounts of $475 million, $400 million, $275 million, 
$325 million and $300 million (cumulative, $2,500 per share liquidation values), respectively, which have substantially the 
same payment terms as the respective trust securities.

The Series F, Series G, Series H, Series J and Series K Preference Stock and the corresponding trust securities do not have a 
maturity date. Upon any redemption of any shares of the Series F, Series G, Series H, Series J or Series K Preference Stock, a 
corresponding dollar amount of trust securities will be redeemed by the applicable trust (see Note 12 for further information). 
The applicable trust will make distributions at the same rate and on the same dates on the applicable series of trust securities 
if and when the SCE board of directors declares and makes dividend payments on the related Preference Stock. The 
applicable trust will use any dividends it receives on the related Preference Stock to make its corresponding distributions on 
the applicable series of trust securities. If SCE does not make a dividend payment to any of these trusts, SCE would be 
prohibited from paying dividends on its common stock. SCE has fully and unconditionally guaranteed the payment of the 
trust securities and trust distributions, if and when SCE pays dividends on the related Preference Stock.

60

The Trust I, Trust II, Trust III and Trust IV balance sheets as of December 31, 2016 and 2015 consisted of investments of               
$475 million, $400 million, $275 million and $325 million in the Series F, Series G, Series H and Series J Preference Stock 
respectively, $475 million, $400 million, $275 million and $325 million of trust securities, respectively and $10,000 each of 
common stock. The Trust V balance sheet as of December 31, 2016 consisted of investments of $300 million in the Series K 
Preference Stock, $300 million of trust securities, and $10,000 of common stock.

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 December 31, 2016 and 2015, 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 Intercontinental Exchange) for 
similar instruments and discount rates. A primary price source that best represents trade activity for each market is used to 
develop observable forward market prices in determining the fair value of these positions. Broker quotes, prices from 
exchanges or comparison to executed trades are used to validate and corroborate the primary price source. These price 
quotations reflect mid-market prices (average of bid and ask) and are obtained from sources believed to provide the most 
liquid market for the commodity. 

Level 3 – The fair value of SCE's Level 3 assets and liabilities is determined using the income approach through various 
models and techniques that require significant unobservable inputs. This level includes tolling arrangements and 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.

61

Assumptions are made in order to value derivative contracts in which observable inputs are not available. Changes in fair 
value are based on changes to forward market prices, including extrapolation of short-term observable inputs into forecasted 
prices for illiquid forward periods. In circumstances where fair value cannot be verified with observable market transactions, 
it is possible that a different valuation model could produce a materially different estimate of fair value. Modeling 
methodologies, inputs and techniques are reviewed and assessed as markets continue to develop and more pricing 
information becomes available and the fair value is adjusted when it is concluded that a change in inputs or techniques would 
result in a new valuation that better reflects the fair value of those derivative contracts. See Note 6 for a discussion of fair 
value 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 significant transfers between any levels during 2016 and 2015.

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.

Level 3 Fair Value Sensitivity

Congestion Revenue Rights

For CRRs, where SCE is the buyer, generally increases (decreases) in forecasted load in isolation would result in increases 
(decreases) to the fair value. In general, an increase (decrease) in electricity and gas prices at illiquid locations tends to result 
in increases (decreases) to fair value; however, changes in electricity and gas prices in opposite directions may have varying 
results on fair value.

Tolling Arrangements

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

For tolling arrangements where SCE is the buyer, increases in volatility of the underlying commodity prices would result in 
increases to fair value as it represents greater price movement risk. As power and gas prices increase, the fair value of tolling 
arrangements tends to increase. The valuation of tolling arrangements is also impacted by the correlation between gas and 
power prices. As the correlation increases, the fair value of tolling arrangements tends to decline.

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.

SCE's investment policies and CPUC requirements place limitations on the types and investment grade ratings of the 
securities that may be held by the nuclear decommissioning trust funds. These policies restrict the trust funds from holding 
alternative investments and limit the trust funds' exposures to investments in highly illiquid markets. With respect to equity 
and fixed income securities, the trustee obtains prices from third-party pricing services which SCE is able to independently 

64

corroborate as described below. The trustee monitors prices supplied by pricing services, including reviewing prices against 
defined parameters' tolerances and performs research and resolves variances beyond the set parameters. SCE corroborates the 
fair values of securities by comparison to other market-based price sources obtained by SCE's investment managers. 
Differences outside established thresholds are followed-up with the trustee and resolved. For each reporting period, SCE 
reviews the trustee determined fair value hierarchy and overrides the trustee level classification when appropriate.

As of December 31, 2016 and 2015, indirect subsidiaries of Edison Energy Group owning solar projects had approximately 
$22 million and $25 million outstanding under a 7-year term financing due in 2022 at a weighted average interest rate of 
3.50% and 3.11%. In addition, tax equity investors in these solar projects receive 99% of taxable profits and losses and tax 
credits of the projects as determined for federal income tax purposes for a six-year period following the completion of the 
portfolio of projects and receive a priority return of 2% of their investment per year. After the six-year period, the tax equity 
investor receives 5% of the taxable profits and losses and cash flow. A subsidiary of Edison Energy Group has a call option 
for a nine-month period following five years after completion of the portfolio of projects to purchase the tax equity investors 
interest and the tax equity investor has the right to put its ownership interest to such subsidiary in the event that the call 
option is not exercised. 

An indirect subsidiary of Edison Energy Group also entered into a non-recourse debt financing to support equity 
contributions in certain solar projects through June 30, 2017. The maturity date of the borrowings under this agreement is 
December 31, 2036. As of December 31, 2016 and 2015, there was $10 million and $6 million outstanding under this 
agreement at a weighted average interest rate of 9%. 

Liens and Security Interests

Almost all of SCE's properties are subject to a trust indenture lien. SCE has pledged first and refunding mortgage bonds as 
collateral for borrowed funds obtained from pollution-control bonds issued by government agencies. SCE has a debt 
covenant that requires a debt to total capitalization ratio be met. At December 31, 2016, SCE was in compliance with this 
debt covenant. 

All of the properties subject to the Edison Energy Group project financings discussed above are subject to a lien.

SCE and Edison International Parent have multi-year revolving credit facilities of $2.75 billion and $1.25 billion, 
respectively, with both maturing in July 2021. SCE's credit facility is generally used to support commercial paper borrowings 
and letters of credit issued for procurement-related collateral requirements, balancing account undercollections and for 
general corporate purposes, including working capital requirements to support operations and capital expenditures. Edison 
International Parent's credit facility is used to support commercial paper borrowings and for general corporate purposes. 

At December 31, 2016, commercial paper supported by SCE's credit facility, net of discount, was $769 million at a weighted-
average interest rate of 0.9%. At December 31, 2016, letters of credit issued under SCE's credit facility aggregated 
$91 million and are scheduled to expire in twelve months or less. At December 31, 2015, the outstanding commercial paper, 
net of discount, was $49 million at a weighted-average interest rate of 0.51%.

66

At December 31, 2016, Edison International Parent's outstanding commercial paper, net of discount, was $538 million at a 
weighted-average interest rate of 0.97%. This commercial paper was supported by the $1.25 billion multi-year revolving 
credit facility. At December 31, 2015, the outstanding commercial paper, net of discount, was $646 million at a weighted-
average interest rate of 0.78%.

Debt Financing Subsequent to December 31, 2016

In January 2017, SCE borrowed $300 million under a Term Loan Agreement with a variable interest rate, initially set at 
1.483%, due in July 2018. The proceeds were used for general corporate purposes.

In January 2017, SCE reissued $135 million of 2.625% pollution-control bonds with a mandatory purchase date in December 
2023. These bonds mature in November 2033. The proceeds were used for general corporate purposes.

Note 6.  Derivative Instruments

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

Commodity Price Risk

Commodity price risk represents the potential impact that can be caused by a change in the market value of a particular 
commodity. SCE's electricity price exposure arises from energy purchased from and sold to wholesale markets as a result of 
differences between SCE's load requirements and the amount of energy delivered from its generating facilities and power 
purchase agreements. SCE's natural gas price exposure arises from natural gas purchased for the Mountainview power plant 
and peaker plants, QF contracts where pricing is based on a monthly natural gas index and power purchase agreements in 
which SCE has agreed to provide the natural gas needed for generation, referred to as tolling arrangements.

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 contracts contain master netting agreements or similar agreements, which generally allow counterparties 
subject to the agreement to setoff 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 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 $12 million and 
$38 million as of December 31, 2016 and 2015, respectively, for which SCE has posted $12 million collateral and no 
collateral to its counterparties at the respective dates for its derivative liabilities and related outstanding payables. If the 
credit-risk-related contingent features underlying these agreements were triggered on December 31, 2016, SCE would be 
required to post $4 million of additional collateral of which $4 million is related to outstanding payables that are net of 
collateral already posted.

67

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 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:

In addition, at December 31, 2016, SCE received $2 million of collateral that is not offset against derivative assets and is reflected in 
"Other current liabilities" on the consolidated balance sheets. At December 31, 2015, SCE had posted $31 million of cash collateral that 
is not offset against derivative liabilities and is reflected in "Other current assets" on the consolidated balance sheets.

Income Statement Impact of Derivative Instruments

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

1   Deferred tax assets for net operating loss and tax credit carryforwards are reduced by unrecognized tax benefits of $176 million and     

$82 million for Edison International and SCE, respectively.

Edison International has recorded a valuation allowance of $24 million for state net operating loss carryforwards estimated to 
expire unused. In 2016, Edison International determined that $8 million of the assets subject to a valuation allowance, had no 
expectation of recovery and were written off.

At December 31, 2015, Edison International and SCE had $42 million and $6 million, respectively, of federal net operating 
loss carryforwards related to the tax benefit on employee stock plans that would be recorded to additional paid-in capital when 
realized. In March 2016, the FASB issued an accounting standards update to simplify the accounting for share-based 
payments. As part of this new guidance adopted in 2016, Edison International and SCE recorded an increase to beginning 
retained earnings for these amounts. Refer to Note 1 for further information.  

Edison International consolidates for federal income tax purposes, but not for financial accounting purposes, a group of wind 
projects referred to as Capistrano Wind. The amount of net operating loss and tax credit carryforwards recognized as part of 
deferred income taxes includes $242 million and $210 million related to Capistrano Wind at December 31, 2016 and 2015, 

70

 
 
 
 
respectively. Under a tax allocation agreement, Edison International has recorded the liability as part of other long-term 
liabilities related to its obligation to make payments to Capistrano Wind of these tax benefits when realized.

Includes incremental repair benefits. See discussion of repair deductions below.

Includes state taxes of $(4) million and $(1) million for Edison International and SCE, respectively. Refer to Note 1 for further 
information.

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. 

Repair Deductions

Edison International made voluntary elections in 2009 and 2011 to change its tax accounting method for certain tax repair 
costs incurred on SCE's transmission, distribution and generation assets. Incremental repair deductions represent amounts 
recognized for regulatory accounting purposes in excess of amounts included in the authorized revenue requirements through 
the GRC proceedings. Incremental repair deductions for the years 2012 – 2014 resulted in additional income tax benefits of 
$133 million in 2014.

As part of the final decision in SCE's 2015 GRC, the CPUC adopted a rate base offset associated with these incremental tax 
repair deductions during 2012 – 2014. The 2015 rate base offset is $324 million and amortizes on a straight line basis over 27 
years. As a result of the rate base offset included in the final decision, SCE recorded an after tax charge of $382 million in 
2015 to write down the net regulatory asset for recovery of deferred income taxes related to 2012 – 2014 incremental tax 
repair deductions which is reflected in "Income tax expense" on the consolidated statements of income. The amount of tax 
repair deductions the CPUC used to establish the rate base offset was based on SCE's forecast of 2012 – 2014 tax repair 
deductions from the Notice of Intent filed in the 2015 GRC. The amount of tax repair deductions included in the Notice of 
Intent was less than the actual tax repair deductions SCE reported on its 2012 through 2014 income tax returns. In April 2016,

the CPUC granted SCE's request to reduce SCE's BRRBA by $234 million in future periods subject to the timing and final 
outcome of audits that may be conducted by tax authorities. The refunds will result in flowing incremental tax benefits for 
2012 – 2014 to customers. SCE refunded $133 million ($79 million after-tax) during the second quarter of 2016. SCE did not 
record a gain or loss from this reduction. Regulatory assets recorded from flow through tax benefits are recovered through 
SCE's general rate case proceedings.

Accounting for Uncertainty in Income Taxes

Authoritative guidance related to accounting for uncertainty in income taxes requires an enterprise to recognize, in its financial 
statements, the best estimate of the impact of a tax position by determining if the weight of the available evidence indicates it 
is more likely than not, based solely on the technical merits, that the position will be sustained upon examination. The 
guidance requires the disclosure of all unrecognized tax benefits, which includes both the reserves recorded for tax positions 
on filed tax returns and the unrecognized portion of affirmative claims.

1    Decreases in prior year tax positions for 2016 relate to state tax receivables on various claims. Due to the tax risks associated with these 
claims, the tax benefits were fully reserved at the time the asset was recorded. During 2016, the Company has determined that it will not 
recognize these assets so the tax benefit and related tax reserve were written off. Decreases in tax positions for 2015 relate primarily to 
re-measurement of uncertain tax positions in connection with receipt of the IRS Revenue Agent Report in June 2015. See discussions in 
Tax Disputes below.  

2  

In the fourth quarter of 2014, Edison International has settled all open tax positions with the IRS for taxable years 2003 through 2006. 

As of December 31, 2016 and 2015, if recognized, $347 million and $440 million, respectively, of the unrecognized tax 
benefits would impact Edison International's effective tax rate; and $243 million and $256 million, respectively, of the 
unrecognized tax benefits would impact SCE's effective tax rate.

Tax Disputes

Tax Years 2007 – 2012 

Edison International has reached a tentative settlement agreement with the IRS for the 2007 – 2012 tax years. The final 
agreement, when approved, is not expected to have a material impact on the financial statements.

During 2015, the Company received the IRS Revenue Agent Report for the 2010 – 2012 tax years. Edison International's and 
SCE's tax reserves were re-measured at that time and $94 million and $100 million, respectively, of income tax benefits were 
recorded in the comparable quarter for the prior year.

Tax years that remain open for examination by the IRS and the California Franchise Tax Board are 2007 – 2015 and                  
2003 – 2015, respectively.

Pension Plans and Postretirement Benefits Other Than Pensions

Pension Plans

Noncontributory defined benefit pension plans (some with cash balance features) cover most employees meeting minimum 
service requirements. SCE recognizes pension expense for its nonexecutive plan as calculated by the actuarial method used 
for ratemaking. The expected contributions (all by the employer) for Edison International and SCE are approximately 
$136 million and $85 million, respectively, for the year ending December 31, 2017. Annual contributions made by SCE to 
most of SCE's pension plans are anticipated to be recovered through CPUC-approved regulatory mechanisms. 

The funded position of Edison International's pension is sensitive to changes in market conditions. Changes in overall interest 
rate levels significantly affect the company's liabilities, while assets held in the various trusts established to fund Edison 
International's pension are affected by movements in the equity and bond markets. Due to SCE's regulatory recovery 
treatment, a regulatory asset has been recorded equal to the unfunded status (See Note 10).

Includes the amount of net loss reclassified from other comprehensive loss. The amount reclassified for Edison International and SCE 
was $10 million and $6 million, respectively, for the year ended December 31, 2016. The amount reclassified for Edison International 
and SCE was $14 million and $8 million, respectively, for the year ended December 31, 2015. The amount reclassified for Edison 
International and SCE was $9 million and $4 million, respectively, for the year ended December 31, 2014.

Under GAAP, a settlement is recorded when lump-sum payments exceed estimated annual service and interest costs. Lump-
sum payments to employees retiring in 2014 from the SCE Retirement Plan (primarily due to workforce reductions described 
below) exceeded the estimated service and interest costs for that year. A settlement requires re-measurement of both the plan 
pension obligations and plan assets as of the date of the settlement. Re-measurement assumption changes result in actuarial 
gains and losses which are combined with previous unrecognized gains and losses. After re-measurement, GAAP requires an 
acceleration of a portion of unrecognized net losses attributable to such lump-sum payments as additional pension expense as 
reflected in the above table. The additional pension expense related to SCE did not impact net income as such amounts are 
probable of recovery through future rates.

Postretirement Benefits Other Than Pensions ("PBOP(s)")

Most employees retiring at or after age 55 with at least 10 years of service may be eligible for postretirement medical, dental, 
vision and life insurance benefits. Eligibility for a company contribution toward the cost of these 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 Welfare Benefit Plan ("PBOP Plan") each participating employer (Edison International or its 
participating subsidiaries) is responsible for the costs and expenses of all PBOP benefits with respect to its employees and 
former employees. A participating employer may terminate the PBOP benefits with respect to its employees and former 
employees, as may SCE (as Plan sponsor), and, accordingly, the participants' PBOP benefits are not vested benefits. 

The expected contributions (substantially all of which are expected to be made by SCE) for PBOP benefits are $21 million 
for the year ended December 31, 2017. 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. 

SCE has established three voluntary employee beneficiary associations trusts ("VEBA Trusts") that can only be used to pay 
for retiree health care benefits of SCE. Once funded into the VEBA Trusts, neither SCE nor Edison International can 
subsequently terminate benefits and recover remaining amounts in the VEBA Trusts. Participants of the PBOP Plan do not 
have a beneficial interest in the VEBA Trusts. The VEBA Trust assets are sensitive to changes in market conditions. Changes 
in overall interest rate levels significantly affect the company's liabilities, while assets held in the various trusts established to 

76

 
fund Edison International's other postretirement benefits are affected by movements in the equity and bond markets. Due to 
SCE's regulatory recovery treatment, the unfunded status is offset by a regulatory asset.

During 2016 and 2015, the PBOP plan had actuarial gains of $110 million and $500 million, respectively. The 2016 actuarial 
gain is primarily related to $165 million in experience gain, offsetting by $95 million loss from a decrease in the discount rate 
(from 4.55% as of December 31, 2015 to 4.29% as of December 31, 2016), and the adoption of new mortality tables, as 
discussed below. The 2015 actuarial gain is primarily related to $300 million in experience gains, $140 million of income 
from an increase in the discount rate (from 4.16% at December 31, 2014 to 4.55% as of December 31, 2015) due to higher 
interest rates, and the adoption of new mortality tables, as discussed below.

In 2016 and 2015, Edison International and SCE adopted new mortality tables that the Society of Actuaries released in 
October each year that reflect changes in life expectancy. At December 31, 2016 and 2015, this adoption resulted in a change 
in Edison International's PBOP plans' accumulated postretirement benefit obligation of $(40) million and $(62) million, 
respectively, including $(40) million and $(61) million, respectively, for SCE.

Description of Pension and Postretirement Benefits Other than Pensions Investment Strategies

The investment of plan assets is overseen by a fiduciary investment committee. Plan assets are invested using a combination 
of asset classes, and may have active and passive investment strategies within asset classes. Target allocations for 2016 
pension plan assets were 29% for U.S. equities, 17% for non-U.S. equities, 35% for fixed income, 15% for opportunistic and/
or alternative investments and 4% for other investments. Target allocations for 2016 PBOP plan assets (except for 
Represented VEBA which is 85% for fixed income, 10% for opportunistic/private equities, and 5% global equities) are 41% 
for U.S. equities, 17% for non-U.S. equities, 34% for fixed income, 7% for opportunistic and/or alternative investments, and 
1% for other investments. Edison International employs multiple investment management firms. Investment managers within 
each asset class cover a range of investment styles and approaches. Risk is managed through diversification among multiple 
asset classes, managers, styles and securities. Plan asset classes and individual manager performances are measured against 
targets. Edison International also monitors the stability of its investment managers' organizations.

Allowable investment types include:

•  United States Equities: Common and preferred stocks of large, medium, and small companies which are predominantly 

United States-based.

•  Non-United States Equities: Equity securities issued by companies domiciled outside the United States and in depository 

receipts which represent ownership of securities of non-United States companies.

•  Fixed Income: Fixed income securities issued or guaranteed by the United States government, non-United States 

governments, government agencies and instrumentalities including municipal bonds, mortgage backed securities and 
corporate debt obligations. A portion of the fixed income positions may be held in debt securities that are below 
investment grade.

Opportunistic, Alternative and Other Investments:

•  Opportunistic: Investments in short to intermediate term market opportunities. Investments may have fixed income and/or 

equity characteristics and may be either liquid or illiquid.

•  Alternative: Limited partnerships that invest in non-publicly traded entities.

•  Other: Investments diversified among multiple asset classes such as global equity, fixed income currency and 

commodities markets. Investments are made in liquid instruments within and across markets. The investment returns are 
expected to approximate the plans' expected investment returns.

Asset class portfolio weights are permitted to range within plus or minus 3%. Where approved by the fiduciary investment 
committee, futures contracts are used for portfolio rebalancing and to reallocate portfolio cash positions. Where authorized, a 
few of the plans' investment managers employ limited use of derivatives, including futures contracts, options, options on 
futures and interest rate swaps in place of direct investment in securities to gain efficient exposure to markets. Derivatives are 
not used to leverage the plans or any portfolios.

Determination of the Expected Long-Term Rate of Return on Assets

The overall expected long-term rate of return on assets assumption is based on the long-term target asset allocation for plan 
assets and capital markets return forecasts for asset classes employed. A portion of the PBOP trust asset returns are subject to 
taxation, so the expected long-term rate of return for these assets is determined on an after-tax basis.

Capital Markets Return Forecasts

SCE's capital markets return forecast methodologies primarily use a combination of historical market data, current market 
conditions, proprietary forecasting expertise, complex models to develop asset class return forecasts and a building block 
approach. The forecasts are developed using variables such as real risk-free interest, inflation, and asset class specific risk 
premiums. For equities, the risk premium is based on an assumed average equity risk premium of 5% over cash. The 
forecasted return on private equity and opportunistic investments are estimated at a 2% premium above public equity, 
reflecting a premium for higher volatility and lower liquidity. For fixed income, the risk premium is based off of a 
comprehensive modeling of credit spreads.

Fair Value of Plan Assets

The PBOP Plan and the Southern California Edison Company Retirement Plan Trust (Master Trust) assets include 
investments in equity securities, U.S. treasury securities, other fixed-income securities, common/collective funds, mutual 
funds, other investment entities, foreign exchange and interest rate contracts, and partnership/joint ventures. Equity securities, 
U.S. treasury securities, mutual and money market funds are classified as Level 1 as fair value is determined by observable, 
unadjusted quoted market prices in active or highly liquid and transparent markets. The fair value of the underlying 
investments in equity mutual funds are based on stock-exchange prices. The fair value of the underlying investments in fixed-
income mutual funds and other fixed income securities including municipal bonds are 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.  Foreign exchange and interest rate 
contracts are classified as Level 2 because the values are based on observable prices but are not traded on an exchange. 
Futures contracts trade on an exchange and therefore are classified as Level 1. Common/collective funds and partnerships are 
measured at fair value using the net asset value per share ("NAV") and have not been classified in the fair value hierarchy. 
Other investment entities are valued similarly to common/collective funds and are therefore classified as NAV. The Level 1 
registered investment companies are either mutual or money market funds. The remaining funds in this category are readily 
redeemable and classified as NAV and are discussed further at Note 8 to the pension plan master trust investments table 
below.

Edison International reviews the process/procedures of both the pricing services and the trustee to gain an understanding of 
the inputs/assumptions and valuation techniques used to price each asset type/class. The trustee and Edison International's 
validation procedures for pension and PBOP equity and fixed income securities are the same as the nuclear decommissioning 
trusts. For further discussion see Note 4. The values of Level 1 mutual and money market funds are publicly quoted. The 
trustees obtain the values of common/collective and other investment funds from the fund managers. The values of 
partnerships are based on partnership valuation statements updated for cash flows. SCE's investment managers corroborate 
the trustee fair values.

Stock-Based Compensation

Edison International maintains a shareholder approved incentive plan (the 2007 Performance Incentive Plan) that includes 
stock-based compensation. The maximum number of shares of Edison International's common stock authorized to be issued 
or transferred pursuant to awards under the 2007 Performance Incentive Plan, as amended, is 66 million shares, plus the 
number of any shares awarded under Edison International's prior plans that are outstanding as of April 26, 2007, which 
expire, cancel or terminate without being exercised or shares being issued ("carry-over shares"). As of December 31, 2016, 
Edison International had approximately 32 million shares remaining available for new award grants under its stock-based 
compensation plans.

statements of cash flows, "Common stock" in Edison International's consolidated balance sheets and "Additional paid-in capital" in 
SCE's consolidated balance sheets. Edison International and SCE adopted the new accounting guidance for shared-based payments, see 
Note 1 for further information.

Stock Options

Under various plans, Edison International has granted stock options at exercise prices equal to the closing price at the grant 
date. Prior to 2007, average of the high and low price was used. Edison International may grant stock options and other 
awards related to, or with a value derived from, its common stock to directors and certain employees. Options generally 
expire 10 years after the grant date and vest over a period of four years of continuous service, with expense recognized 
evenly over the requisite service period, except for awards granted to retirement-eligible participants, as discussed in "Stock-
Based Compensation" in Note 1. Additionally, Edison International will substitute cash awards to the extent necessary to pay 
tax withholding or any government levies.

The fair value for each option granted was determined as of the grant date using the Black-Scholes option-pricing model. The 
Black-Scholes option-pricing model requires various assumptions noted in the following table:

The expected term represents the period of time for which the options are expected to be outstanding and is primarily based 
on historical exercise and post-vesting cancellation experience and stock price history. The risk-free interest rate for periods 
within the contractual life of the option is based on a zero coupon U.S. Treasury STRIPS (separate trading of registered 
interest and principal of securities) whose maturity equals the option's expected term on the measurement date. Expected 
volatility is based on the historical volatility of Edison International's common stock for the length of the option's expected 
term for 2016. The volatility period used was 71 months, 71 months and 72 months at December 31, 2016, 2015 and 2014, 
respectively.

A target number of contingent performance shares were awarded to executives in March 2016, 2015 and 2014 and vest at 
December 31, 2018, 2017 and 2016, respectively. The vesting of the grants is dependent upon market and financial 
performance and service conditions as defined in the grants for each of the years. The number of performance shares earned 
from each year's grants could range from zero to twice the target number (plus additional units credited as dividend 
equivalents). Performance shares awarded in 2014 that are earned are settled half in cash and half in common stock, while 
performance shares awarded in 2016 and 2015 that are earned are settled solely in cash. The portion of performance shares 
that can be settled in cash is classified as a share-based liability award. The fair value of these shares is remeasured at each 
reporting period, and the related compensation expense is adjusted. The portion of performance shares payable in common 
stock is classified as a share-based equity award. Compensation expense related to these shares is based on the grant-date fair 
value, which for each share is determined as the closing price of Edison International common stock on the grant date. 
However, with respect to the portion of the performance shares payable in common stock that is subject to the financial 
performance condition defined in the grants, the number of performance shares expected to be earned is subject to revision 
and updated at each reporting period, with a related adjustment to compensation expense. Performance shares expense is 
recognized ratably over the requisite service period based on the fair values determined (subject to the adjustments discussed 
above), except for awards granted to retirement-eligible participants.

The fair value of market condition performance shares is determined using a Monte Carlo simulation valuation model.

Restricted Stock Units

Restricted stock units were awarded to Edison International's and SCE's executives in March 2016, 2015 and 2014 and vest 
and become payable on January 2, 2019, January 2, 2018 and January 3, 2017, respectively. Each restricted stock unit 
awarded includes a dividend equivalent feature and is a contractual right to receive one share of Edison International 
common stock, if vesting requirements are satisfied. The vesting of Edison International's restricted stock units is dependent 
upon continuous service through the end of the vesting period, except for awards granted to retirement-eligible participants.

Workforce Reductions

SCE continues to focus on productivity improvements to mitigate rate pressure from its capital program, optimize its cost 
structure and improve operational efficiency. During the year ended December 31, 2016, SCE increased the estimated impact 
for approved workforce reductions. 

The following table provides a summary of changes in the accrued severance liability associated with these reductions:

Trust assets are used to pay income taxes as the Trust files separate income taxes returns from SCE. Deferred tax liabilities 
related to net unrealized gains at December 31, 2016 were $348 million. Accordingly, the fair value of Trust assets available to 
pay future decommissioning costs, net of deferred income taxes, totaled $3.9 billion at December 31, 2016. Due to regulatory 
mechanisms, changes in assets of the trusts from income or loss items have no impact on operating revenue or earnings.

Beginning in 2016, funds for decommissioning costs are requested from the nuclear decommissioning trusts one month in 
advance. Decommissioning disbursements are funded from sales of investments of the nuclear decommissioning trusts. 

Acquisitions

On December 31, 2015, Edison Energy acquired three businesses for an aggregate purchase price of approximately $100 
million, of which $90 million was allocated to goodwill and identifiable intangibles. Under the terms of the acquisition of one 
of the agreements, the sellers were entitled to additional consideration (earn-out) in the event that certain financial thresholds 
were achieved. During the second quarter of 2016, Edison Energy entered into an agreement to buy-out this earn-out provision 
and recorded an after-tax charge of $13 million. The buy-out was completed, together with modification to employment 
contracts, in order to align long-term incentive compensation.

During 2016, a subsidiary of SoCore Energy agreed to acquire equity interests in solar garden development projects in 
Minnesota as part of the SunEdison bankruptcy proceedings, subject to certain conditions. The maximum purchase price is 
$41.9 million if all projects achieve the required conditions. SoCore Energy would also reimburse SunEdison up to 
$8.7 million of project-specific interconnection costs. Not all of the projects are expected to achieve the closing conditions. 
Through February 1, 2017, SoCore Energy acquired four of these development projects (28 MWdc) for $10.5 million.

Note 10.  Regulatory Assets and Liabilities

Included in SCE's regulatory assets and liabilities are regulatory balancing accounts. CPUC authorized balancing account 
mechanisms require SCE to refund or recover any differences between forecasted and actual costs. The CPUC has authorized 
balancing accounts for specified costs or programs such as fuel, purchased-power, demand-side management programs, 
nuclear decommissioning and public purpose programs. Certain of these balancing accounts include a return on rate base of 
7.90% in 2016 and 2015. The CPUC also authorizes the use of a balancing account to recover from or refund to customers 
differences in revenue resulting from actual and forecasted electricity sales.

Amounts included in regulatory assets and liabilities are generally recorded with corresponding offsets to the applicable 
income statement accounts.

SCE's regulatory assets related to energy derivatives are primarily an offset to unrealized losses on derivatives. The regulatory 
asset changes based on fluctuations in the fair market value of the contracts, in which the original contracts expire in 10 to 45 
years. 

SCE's current and long-term unamortized investments include legacy meters retired as part of the Edison SmartConnect® 
program. SCE's unamortized investments related to legacy meters are expected to be recovered by 2017 and earned a rate of 
return of 6.46% in 2016 and 2015. 

SCE's regulatory assets related to deferred income taxes represent tax benefits passed through to customers. The CPUC 
requires SCE to flow through certain deferred income tax benefits to customers by reducing electricity rates, thereby deferring 
recovery of such amounts to future periods. Based on current regulatory ratemaking and income tax laws, SCE expects to 
recover its regulatory assets related to deferred income taxes over the life of the assets that give rise to the accumulated 
deferred income taxes, approximately from 1 to 60 years. 

SCE's regulatory assets related to pensions and other post-retirement plans represent the unfunded net loss and prior service 
costs of the plans (see "Pension Plans and Postretirement Benefits Other than Pensions" discussion in Note 8). This amount is 
being recovered through rates charged to customers. 

SCE's unamortized investments long-term primarily include nuclear assets related to Palo Verde. Nuclear assets related to Palo 
Verde are expected to be recovered by 2047 and earned a return of 7.90% in 2016 and 2015. 

In accordance with the San Onofre OII Settlement Agreement, SCE is authorized to recover in rates its San Onofre regulatory 
asset, generally over a ten-year period commencing February 1, 2012. Under the San Onofre OII Settlement Agreement (see 
Note 11), SCE was allowed to earn a rate of return of 2.62% in 2016 and 2015 and is authorized to continue to earn this rate as 
adjusted during the amortization period thereafter with changes in SCE's authorized return on debt and preferred equity. SCE's 
regulatory assets related to San Onofre nuclear fuel will earn a return equal to commercial paper rate that the CPUC uses to 
calculate interest on balancing accounts. In a December 2016 joint ruling, the Assigned Commissioner and the Assigned ALJ 
directed SCE to meet and confer with the other parties in the OII to consider changing the terms of the San Onofre OII 
Settlement Agreement. See Note 11 for further information.

90

 
 
 
SCE's net regulatory asset related to its unamortized loss on reacquired debt will be recovered over the original amortization 
period of the reacquired debt over periods ranging from 10 to 35 years.

SCE's regulatory assets related to environmental remediation represents a portion of the costs incurred at certain sites that SCE 
is allowed to recover through customer rates. See "Environmental Remediation" discussed in Note 11.

SCE's regulatory liabilities related to costs of removal represent differences between asset removal costs recorded and 
amounts collected in rates for those costs.

SCE's regulatory liabilities related to recoveries in excess of ARO liabilities represents the cumulative differences between 
ARO expenses and amounts collected in rates primarily for the decommissioning of the SCE's nuclear generation facilities. 
Decommissioning costs recovered through rates are primarily placed in nuclear decommissioning trusts. This regulatory 
liability also represents the deferral of realized and unrealized gains and losses on the nuclear decommissioning trust 
investments. See Note 9.

Net Regulatory Balancing Accounts

Balancing account over and under collections represent differences between cash collected in current rates for specified 
forecasted costs and such costs that are actually incurred. Undercollections are recorded as regulatory balancing account 
assets. Overcollections are recorded as regulatory balancing account liabilities. With some exceptions, SCE seeks to adjust 
rates on an annual basis or at other designated times to recover or refund the balances recorded in its balancing accounts. 
Regulatory balancing accounts that SCE does not expect to collect or refund in the next 12 months are reflected in the long-
term section of the consolidated balance sheets. Regulatory balancing accounts do not have the right of offset and are 
presented gross in the consolidated balance sheets. Under and over collections accrue interest based on a three-month 
commercial paper rate published by the Federal Reserve.

among customers, shareholders, or to offset fuel decommissioning or storage costs. See Note 11 for further discussion.

Note 11.  Commitments and Contingencies

Third-Party Power Purchase Agreements

SCE entered into various agreements, which were approved by the CPUC and met critical contract provisions (including 
completion of major milestones for construction), to purchase power and electric capacity, including:

•  Renewable Energy Contracts – California law requires retail sellers of electricity to comply with a RPS by delivering 

renewable energy, primarily through power purchase contracts. Renewable energy contracts generally contain escalation 
clauses requiring increases in payments. As of December 31, 2016, SCE had 119 renewable energy contracts. 

•  QF Power Purchase Agreements – Under the Public Utility Regulatory Policies Act of 1978 ("PURPA"), electric utilities 
are required, with exceptions, to purchase energy and capacity from independent power producers that are qualifying co-
generation facilities and qualifying small power production facilities or QFs. As of December 31, 2016, SCE had 55 QF 
contracts.

•  Other Power Purchase Agreements – SCE has entered into 30 other power purchase agreements, including combined heat 

and power contracts, tolling arrangements and resource adequacy contracts.

At December 31, 2016, the undiscounted future minimum expected payments for the SCE power purchase agreements that 
have been approved by the CPUC and have completed major milestones for construction were as follows:

The table above includes contractual obligations for power procurement contracts that met the critical contract provisions as of 
December 31, 2016 in which the term is over a year when it was executed. Additionally, SCE has signed contracts that have 
not met the critical contract provisions that would increase contractual obligations by $53 million in 2017, $235 million in 

92

2018, $312 million in 2019, $554 million in 2020, $630 million in 2021 and $9.1 billion thereafter, if all principal provisions 
are completed. 

Costs incurred for power purchase agreements were $3.3 billion in 2016, $3.2 billion in 2015 and $3.8 billion in 2014, which 
include costs associated with contracts with terms of less than one year. 

Many of the power purchase agreements that SCE entered into with independent power producers are accounted for as leases. 
The following table shows the future minimum lease payments due under the contracts that are treated as operating and capital 
leases (these amounts are also included in the table above). Due to the inherent uncertainty associated with the reliability of 
the fuel source, expected purchases from most renewable energy contracts do not meet the definition of a minimum lease 
payment and have been excluded from the operating and capital lease table below but remain in the table above. The future 
minimum lease payments for capital leases are discounted to their present value in the table below using SCE's incremental 
borrowing rate at the inception of the leases. The amount of this discount is shown in the table below as the amount 
representing interest.

Operating lease expense for power purchase agreements was $1.9 billion in 2016, and $1.7 billion in both 2015 and 
2014 (including contingent rents of $1.4 billion in 2016, $1.1 billion in 2015 and $944 million in 2014). Contingent rents for 
capital leases were $109 million in 2016 and less than $1 million in both 2015 and 2014. The timing of SCE's recognition of 
the lease expense conforms to ratemaking treatment for SCE's recovery of the cost of electricity and is included in purchased 
power.

Costs incurred for other commitments were $141 million in 2016, $182 million in 2015 and $90 million in 2014. SCE has fuel 
supply contracts for Palo Verde which require payment only if the fuel is made available for purchase. SCE also has 
commitments related to maintaining reliability and expanding SCE's transmission and distribution system. 

The table above excludes other contractual obligations that have not met the critical contract provisions. As of December 31, 
2016, SCE has signed capacity reduction contracts that have not met critical contract provisions and are, therefore, not 
included in the table above. These contracts would increase the contractual obligations by $3 million in 2017, $24 million in 
2018, $94 million in 2019, $93 million in 2020, $71 million in 2021, and $478 million thereafter, if all principal provisions are 
completed.

The table above does not include asset retirement obligations, which are discussed in Note 1.

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 provided 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 indemnified the City of Redlands, California in connection with Mountainview's California Energy Commission 
permit for cleanup or associated actions related to groundwater contaminated by perchlorate due to the disposal of filter cake 
at the City's solid waste landfill. The obligations under this agreement are not limited to a specific time period or subject to a 
maximum liability. SCE has not recorded a liability related to this indemnity.

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.

San Onofre Related Matters

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, which resolved the CPUC's investigation 
regarding the steam generator replacement project at San Onofre and the related outages and subsequent shutdown of San 
Onofre. Subsequently, the San Onofre OII proceeding record was reopened by a joint ruling of the Assigned Commissioner 
and the Assigned ALJ to consider whether, in light of the Company not reporting certain ex parte communications on a timely 
basis, the San Onofre OII 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. In comments filed with the CPUC in July 
2016, SCE asserted that the Settlement Agreement continues to meet this standard and therefore should not be disturbed. A 
number of the parties to the OII, however, have requested that the CPUC either modify the San Onofre OII Settlement 
Agreement or vacate its previous approval of the settlement and reinstate the OII for further proceedings. 

94

In a December 2016 joint ruling, the Assigned Commissioner and the Assigned ALJ expressed concerns about the extent to 
which the failure to timely report ex parte communications had impacted the settlement negotiations and directed SCE to meet 
and confer with the other parties in the OII to consider changing the terms of the San Onofre OII Settlement Agreement. The 
ruling set out a schedule requiring that at least two meet and confer sessions be held in the first quarter of 2017 and requiring 
the parties to submit a joint status report to the CPUC by April 28, 2017 if no modifications have been agreed to by some or all 
of the parties as a result of the meet and confer process. SCE has recorded a regulatory asset to reflect the expected recoveries 
under the San Onofre OII Settlement Agreement. At December 31, 2016, $857 million remains to be collected. 

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 San Onofre OII 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. The Ninth Circuit cancelled the oral argument 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 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 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. In September 2016, the Court granted defendants' motion to 
dismiss the complaint, with an opportunity for plaintiff to amend the complaint. Plaintiff filed an amended complaint and 
defendants again moved to dismiss the complaint in October 2016. 

Also in July 2015, a federal shareholder derivative lawsuit was filed against members of the Edison International Board of 
Directors for breach of fiduciary duty and other claims. The federal derivative lawsuit is based on similar allegations to the 
federal class action securities lawsuit and seeks monetary damages, including punitive damages, and various corporate 
governance reforms. An additional federal shareholder derivative lawsuit making essentially the same allegations was filed in 
August 2015 and was subsequently consolidated with the July 2015 federal derivative lawsuit. In September 2016, the Court 
granted defendants' motion to dismiss the complaint, with an opportunity for plaintiff to amend the complaint. Plaintiff did not 
file an amended complaint by the required date. 

In October 2015, a shareholder derivative lawsuit was filed in California state court against members of the Edison 
International Board of Directors for breach of fiduciary duty and other claims, making similar allegations to those in the 
federal derivative lawsuits discussed above. The California state court action is currently on hold in light of the pending 
federal suits discussed above.

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 ("ERISA"). 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. Defendants' motion was heard by the court in November 2016 and a decision is pending. 

Edison International and SCE cannot predict the outcome of these proceedings.

MHI Claims

SCE is also pursuing claims against Mitsubishi Heavy Industries, Ltd. and a related company ("MHI"), which designed and 
supplied the replacement steam generators. MHI warranted the replacement steam generators for an initial period of 20 years 
from acceptance and is contractually obligated to repair or replace defective items with dispatch and to pay specified damages 
for certain repairs. MHI's stated liability under the purchase agreement is limited to $138 million and excludes consequential 
damages, defined to include "the cost of replacement power;" however, limitations in the contract are subject to applicable 
exceptions both in the contract and under law. SCE has advised MHI that it believes one or more of such exceptions apply and 

95

that MHI's liability is not limited to $138 million. MHI has advised SCE that it disagrees. In October 2013, SCE sent MHI a 
formal request for binding arbitration under the auspices of the International Chamber of Commerce in accordance with the 
purchase contract seeking damages for all losses. In the request for arbitration, SCE alleges contract and tort claims and seeks 
at least $4 billion in damages on behalf of itself and its customers and in its capacity as Operating Agent for San Onofre. MHI 
has denied any liability and has asserted counterclaims for $41 million, for which SCE has denied any liability. Each of the 
other San Onofre owners sued MHI, alleging claims arising from MHI's supplying the faulty steam generators. These litigation 
claims have been stayed pending the arbitration. The other co-owners (San Diego Gas & Electric and Riverside) have been 
added as additional claimants in the arbitration. The arbitration is being conducted pursuant to a confidentiality order issued by 
the arbitration panel. Hearings concluded on April 29, 2016. A decision is expected to be issued in the first quarter of 2017.

SCE, on behalf of itself and the other San Onofre co-owners, has submitted seven invoices to MHI totaling $149 million for 
steam generator repair costs incurred through April 30, 2013. MHI paid the first invoice of $45 million, while reserving its 
right to challenge it and subsequently rejected a portion of the first invoice and has not paid further invoices, claiming further 
documentation is required, which SCE disputes. SCE recorded its share of the invoice paid (approximately $35 million) as a 
reduction of repair and inspection costs in 2012.

Under the San Onofre OII Settlement Agreement, recoveries from MHI (including amounts paid by MHI under the first 
invoice), if any, will first be applied to reimburse costs incurred in pursuing such recoveries, including litigation costs. To the 
extent SCE's share of recoveries from MHI exceed such costs, they will be allocated 50% to customers and 50% to SCE.

The first $282 million of SCE's customers' portion of such recoveries from MHI will be distributed to customers via a credit to 
a sub-account of SCE's BRRBA, reducing revenue requirements from customers. Amounts in excess of the first $282 million 
distributable to SCE customers will reduce SCE's regulatory asset represented by the unamortized balance of investment in 
San Onofre base plant, reducing the revenue requirement needed to amortize such investment. The amortization period, 
however, will be unaffected. Any additional amounts received after the regulatory asset is recovered will be applied to the 
BRRBA.

The San Onofre OII Settlement Agreement provides the utilities with the discretion to resolve the MHI dispute without CPUC 
approval, but the utilities are obligated to use their best efforts to inform the CPUC of any settlement or other resolution of 
these disputes to the extent this is possible without compromising any aspect of the resolution. SCE and SDG&E have also 
agreed to allow the CPUC to review the documentation of any final resolution of the MHI dispute and the litigation costs 
incurred in pursuing claims against MHI to ensure they are not exorbitant in relation to the recovery obtained. There is no 
assurance that there will be any recovery from MHI or that, if there is a recovery, it will equal or exceed the litigation costs 
incurred to pursue the recovery.

Long Beach Service Interruptions

In July 2015, SCE's customers who are served via the network portion of SCE's electric system in Long Beach, California 
experienced service interruptions due to multiple underground vault fires and underground cable failures. No personal injuries 
were reported in connection with these events. SCE expects to incur penalties as a result of these events. Although resolution 
will be subject to settlement discussions with SED and CPUC review and approval, SCE has recorded a liability for the 
estimated loss.

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 December 31, 2016, SCE's recorded estimated minimum liability to remediate its 19 identified material sites (sites with a 
liability balance as of December 31, 2016, in which the upper end of the range of the costs is at least $1 million) was 
$128 million, including $77 million related to San Onofre. In addition to these sites, SCE also has 18 immaterial sites with a 
liability balance at December 31, 2016 for which the total minimum recorded liability was $3 million. Of the $131 million 
total environmental remediation liability for SCE, $126 million has been recorded as a regulatory asset. SCE expects to 
recover $46 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 $80 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 
96

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 $168 million and $8 million, respectively. The upper limit of this range of costs was estimated 
using assumptions least favorable to SCE among a range of reasonably possible outcomes.

SCE expects to clean up and mitigate its identified sites over a period of up to 30 years. Remediation costs for each of the next 
four years are expected to range from $8 million to $20 million. Costs incurred for years ended December 31, 2016, 2015 and 
2014 were $4 million, $5 million and $4 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

Federal law limits public offsite liability claims for bodily injury and property damage from a nuclear incident to the amount 
of available financial protection, which is currently approximately $13.4 billion. As of January 1, 2017, SCE and other owners 
of San Onofre and Palo Verde have purchased the maximum private primary insurance available ($450 million) through a 
Facility Form issued by American Nuclear Insurers ("ANI"). The balance is covered by a loss sharing program among nuclear 
reactor licensees. If a nuclear incident at any licensed reactor in the United States results in claims and/or costs which exceed 
the primary insurance at that plant site, all nuclear reactor licensees could be required to contribute their share of the liability 
in the form of a deferred premium.

The ANI Facility Form coverage includes broad liability protection for bodily injury or offsite property damage caused by the 
nuclear energy hazard at San Onofre, or while in transit to or from San Onofre. The Facility Form, however, includes several 
exclusions. First, it excludes onsite property damage to the nuclear facility itself and onsite cleanup costs, but as discussed 
below SCE maintains separate NEIL property damage coverage for such events. Second, tort claims of onsite workers are 
excluded, but SCE also maintains an ANI Master Worker Form policy that provides coverage for non-licensee workers. This 
program provides a shared industry aggregate limit of $450 million. Industry losses covered by this program could reduce 
limits available to SCE. Third, offsite environmental costs arising out of government orders or directives, including those 
issued under the Comprehensive Environmental Response, Compensation and Liability Act, also known as CERCLA, are 
excluded, with minor exceptions from clearly identifiable accidents.

Based on its ownership interests, SCE could be required to pay a maximum of approximately $255 million per nuclear 
incident. However, it would have to pay no more than approximately $38 million per incident in any one year. If the public 
liability limit above is insufficient, federal law contemplates that additional funds may be appropriated by Congress. This 
could include an additional assessment on all licensed reactor operators as a measure for raising further federal revenue.

NEIL, a mutual insurance company owned by entities with nuclear facilities, issues nuclear property damage and accidental 
outage insurance policies. The amount of nuclear property insurance purchased for San Onofre and Palo Verde exceeds the 
minimum federal requirement of $1.06 billion. These policies include coverage for decontamination liability. Property damage 
insurance also covers damages caused by acts of terrorism up to specified limits. Additional outage insurance covers part of 
replacement power expenses during an accident-related nuclear unit outage. The accidental outage insurance at San Onofre 
has been canceled as a result of the permanent retirement, but that insurance continues to be in effect at Palo Verde.

If losses at any nuclear facility covered by the arrangement were to exceed the accumulated funds for these insurance 
programs, SCE could be assessed retrospective premium adjustments of up to approximately $52 million per year. Insurance 
premiums are charged to operating expense.

Wildfire Insurance

Severe wildfires in California have given rise to large damage claims against California utilities for fire-related losses alleged 
to be the result of the failure of electric and other utility equipment. Invoking a California Court of Appeal decision, plaintiffs 
pursuing these claims have relied on the doctrine of inverse condemnation, which can impose strict liability (including liability 
for a claimant's attorneys' fees) for property damage. Drought conditions in California have also increased the duration of the 
wildfire season and the risk of severe wildfire events. SCE has approximately $1 billion of insurance coverage for wildfire 
liabilities for the period ending on May 31, 2017. SCE has a self-insured retention of $10 million per wildfire occurrence. SCE 
or its contractors may experience coverage reductions and/or increased insurance costs in future years. No assurance can be 
given that future losses will not exceed the limits of SCE's or its contractors' insurance coverage.

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 share $112 million) to recover costs incurred through December 31, 2005 for 
the DOE's failure to meet its obligation to begin accepting spent nuclear fuel from San Onofre. SCE received payment from 
the federal government in the amount of the damage award. In April 2016, SCE, as operating agent, settled a lawsuit on behalf 
of the San Onofre owners against the DOE for $162 million, including reimbursement for legal costs (SCE share 
$124 million) to compensate for damages caused by the DOE's failure to meet its obligation to begin accepting spent nuclear 
fuel for the period from January 1, 2006 to December 31, 2013. The settlement also provides for a claim submission/audit 
process for expenses incurred from 2014 – 2016, where SCE will submit a claim for damages caused by the DOE failure to 
accept spent nuclear fuel each year, followed by a government audit and payment of the claim. This process will make 
additional legal action to recover damages incurred in 2014 – 2016 unnecessary. The first such claim covering damages for 
2014 – 2015 was filed on September 30, 2016 for approximately $56 million. In February 2017, the DOE reviewed the 
2014 – 2015 claim submission and reduced the original request to approximately $43 million primarily due to DOE allocation 
limits. SCE has 30 days to review and accept the DOE's determination. SCE will make the claim submission for 2016 
damages in the third quarter of 2017. All damages recovered by SCE are subject to CPUC review as to how these amounts 
would be distributed among customers, shareholders, or to offset fuel decommissioning or storage costs.

Note 12.  Preferred and Preference Stock of Utility

SCE's authorized shares are: $100 cumulative preferred – 12 million shares, $25 cumulative preferred – 24 million shares and 
preference with no par value – 50 million shares. SCE's outstanding shares are not subject to mandatory redemption. There 
are no dividends in arrears for the preferred or preference shares. Shares of SCE's preferred stock have liquidation and 
dividend preferences over shares of SCE's common stock and preference stock. All cumulative preferred shares are 
redeemable. When preferred shares are redeemed, the premiums paid, if any, are charged to common equity. No preferred 
shares were issued or redeemed in the years ended December 31, 2016, 2015 and 2014. There is no sinking fund requirement 
for redemptions or repurchases of preferred shares.

Shares of SCE's preference stock rank junior to all of the preferred stock and senior to all common stock. Shares of SCE's 
preference stock are not convertible into shares of any other class or series of SCE's capital stock or any other security. There 
is no sinking fund requirement for redemptions or repurchases of preference shares.

Note 15.  Discontinued Operations

EME Chapter 11 Bankruptcy

In December 2012, EME and certain of its wholly-owned subsidiaries filed voluntary petitions for relief under Chapter 11 of 
the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the Northern District of Illinois, Eastern Division. The Amended 
Plan of Reorganization, including the EME Settlement Agreement, was completed on April 1, 2014 with the sale of 
substantially all of EME's assets to NRG Energy, Inc. and the transactions called for in the EME Settlement Agreement, 
including an initial cash payment to the Reorganization Trust of $225 million in April 2014. 

In August 2014, Edison International entered into an amendment of the EME Settlement Agreement that finalized the 
remaining matters related to the EME Settlement including setting the amount of the two installment payments. Edison 
International made an installment payment of $204 million in September 2015 and made the remaining $214 million payment 
in September 2016.

Income from discontinued operations, net of tax, was $12 million (pre-tax income of $1 million), $35 million (pre-tax income 
of $15 million) and $185 million (pre-tax loss of $525 million) for the years ended December 31, 2016, 2015 and 2014, 
respectively. The 2016 and 2015 income was primarily related to the resolution of tax issues related to EME. The 2015 
income also included insurance recoveries. Results from discontinued operations in 2014 consisted of a pre-tax loss of 
$525 million primarily related to liabilities assumed in connection with the EME Settlement Agreement, including the 
payments to the Reorganization Trust discussed above, and income tax benefits of $710 million related to the EME net 
operating loss and other credit carryforwards.

SCE's accrued capital expenditures at December 31, 2016, 2015 and 2014 were $540 million, $543 million, and $837 million, 
respectively. Accrued capital expenditures will be included as an investing activity in the consolidated statements of cash 
flow in the period paid.

During 2015, SCE amended a power contract classified as a capital lease, which resulted in a reduction in the lease obligation 
and asset by $147 million.

Note 17.  Related-Party Transactions

Edison International and SCE provide and receive various services to and from its subsidiaries and affiliates. Services 
provided to Edison International by SCE are priced at fully loaded cost (i.e., direct cost of good or service and allocation of 
overhead cost). Specified administrative services such as payroll, employee benefit programs, all performed by Edison 
International or SCE employees, are shared among all affiliates of Edison International. Costs are allocated based on one of 
the following formulas: percentage of time worked, equity in investment and advances, number of employees, or multi-factor 
(operating revenues, operating expenses, total assets and number of employees). Edison International allocates various 
corporate administrative and general costs to SCE and other subsidiaries using established allocation factors.

In the fourth quarter of 2015, as result of the 2015 GRC Decision, SCE recorded a $382 million write-down of regulatory assets 
previously recorded for recovery of deferred income taxes from 2012 – 2014 incremental tax repair deductions. 

Due to the seasonal nature of Edison International and SCE's business, a significant amount of revenue and earnings are 
recorded in the third quarter of each year. As a result of rounding, the total of the four quarters does not always equal the 
amount for the year.

Subsidiaries of Edison International 

SCE – Public Utility

SCE is an investor-owned public utility primarily engaged in the business of supplying and delivering electricity through 
SCE's electrical infrastructure to an approximately 50,000 square-mile area of southern California. SCE serves approximately 
5 million customers in its service area. In 2016, SCE's total operating revenue of $11.8 billion was derived as follows: 42.0% 
commercial customers, 39.6% residential customers, 3.9% industrial customers, 4.9% public authorities, 2.2% agricultural 
and other, and 7.4% other operating revenue.

Edison Energy Group – Energy Service Provider

Edison Energy Group is a holding company for subsidiaries engaged in pursuing competitive business opportunities across 
energy services and distributed solar to commercial and industrial customers. Energy services are provided through its 
subsidiary, Edison Energy, LLC, to help commercial and industrial customers improve managing of their energy costs and 
risks in dealing with increasingly complex tariff and technology choices. Solar energy solutions are provided through Edison 
Energy Group's subsidiary SoCore Energy and take the form of behind the meter sales of power under power purchase 
agreements or the sale of distributed generation systems directly to the customer (build/transfer contracts) SoCore Energy has 
also developed ground mounted solar projects selling power to rural cooperatives or to subscribers in community solar 
programs. As of December 31, 2016, SoCore Energy had constructed and achieved commercial operations for 94 MW of 
rooftop solar systems in 21 states. Edison Energy Group, through its subsidiary Edison Transmission, LLC, is one of the eight 
founders of Grid AssuranceTM, a limited liability company developing grid resiliency offerings for domestic utilities.

To date, investments in Edison Energy Group are below 1% of the total consolidated assets and, therefore, not material to be 
reported as a business segment.

Regulation of Edison International as a Holding Company

As a public utility holding company, Edison International is subject to the Public Utility Holding Company Act. The Public 
Utility Holding Company Act primarily obligates Edison International and its utility subsidiaries to provide access to their 
books and records to the FERC and the CPUC for ratemaking purposes.

Edison International is not a public utility and its capital structure is not regulated by the CPUC. The 1988 CPUC decision 
authorizing SCE to reorganize into a holding company structure, however, imposed certain obligations on Edison 
International and its affiliates. These obligations include a requirement that SCE's dividend policy shall continue to be 
established by SCE's Board of Directors as though SCE were a stand-alone utility company, and that the capital requirements 
of SCE, as deemed to be necessary to meet SCE's electricity service obligations, shall receive first priority from the Boards of 
Directors of Edison International and SCE. The CPUC has also promulgated Affiliate Transaction Rules, which, among other 
requirements, prohibit holding companies from (1) being used as a conduit to provide non-public information to a utility's 
affiliate and (2) causing or abetting a utility's violation of the rules, including providing preferential treatment to affiliates.

106

Employees and Labor Relations

At December 31, 2016, Edison International and its consolidated subsidiaries had an aggregate of 12,390 full-time 
employees, 11,947 of which were full-time employees at SCE. 

Approximately 3,900 of SCE's full-time employees are covered by collective bargaining agreements with the International 
Brotherhood of Electrical Workers ("IBEW"). The IBEW collective bargaining agreements expire on December 31, 2019. 

Insurance

Edison International maintains a property and casualty insurance program for itself and its subsidiaries and excess liability 
insurance covering liabilities to third parties for bodily injury or property damage resulting from operations. These policies 
are subject to specific retentions, sub-limits and deductibles, which are comparable to those carried by other utility companies 
of similar size. SCE also has separate insurance programs for nuclear property and liability, workers compensation and solar 
rooftop construction. For further information on nuclear and wildfire insurance, see "Notes to Consolidated Financial 
Statements—Note 11. Commitments and Contingencies—Contingencies." 

SCE

Regulation

CPUC

The CPUC has the authority to regulate, among other things, retail rates, energy purchases on behalf of retail customers, SCE 
capital structure, rate of return, issuance of securities, disposition of utility assets and facilities, oversight of nuclear 
decommissioning funding and costs, and aspects of the transmission system planning, site identification and construction, 
including safety and environmental mitigation.

FERC

The FERC has the authority to regulate wholesale rates as well as other matters, including unbundled transmission service 
pricing, rate of return, accounting practices, and licensing of hydroelectric projects. The FERC also has jurisdiction over a 
portion of the retail rates and associated rate design.

CAISO

Major transmission projects required for reliability and accessing renewable resources are recommended by the California 
Independent System Operator ("CAISO") through a regular transmission planning process that highlights the need for and 
key issues associated with each project. Much of SCE’s current transmission investment program is for transmission projects 
that facilitate access to renewable energy resources in desert and mountain regions east and north of its load center to meet 
the 33% renewable mandate by 2020. The CAISO will similarly be initiating long-term transmission planning to meet the 
2030 mandate for SCE to deliver 50% of its energy from qualifying renewable resources.

NERC

The FERC assigned administrative responsibility to the NERC to establish and enforce reliability standards and critical 
infrastructure protection standards, which protect the bulk power system against potential disruptions from cyber and 
physical security breaches. The critical infrastructure protection standards focus on controlling access to critical physical and 
cyber security assets, including supervisory control and data acquisition systems for the electric grid. Compliance with these 
standards is mandatory. The maximum penalty that may be levied for violating a NERC reliability or critical infrastructure 
protection standard is $1 million per violation, per day.

SCE has a formal cyber security program that covers SCE's information technology systems as well as customer data. 
Program staff is engaged with industry groups as well as public-private initiatives to reduce risk and to strengthen the security 
and reliability of SCE's systems and infrastructure. The program is also engaged in the protection of SCE's customer 
information.

Nuclear Power Plant Regulation

The NRC has jurisdiction with respect to the safety of San Onofre and Palo Verde Nuclear Generating Stations. The NRC 
regulates commercial nuclear power plants through licensing, oversight and inspection, performance assessment, and 
enforcement of its requirements. In June 2013, SCE decided to permanently retire and decommission San Onofre. For further 
information, see "Liquidity and Capital Resources—SCE—Decommissioning of San Onofre" in the MD&A.

107

Other Regulatory Agencies

The construction, planning and project site identification of SCE's transmission lines and substation facilities require the 
approval of many governmental agencies and compliance with various laws in addition to the CPUC and FERC. These 
include various state regulatory agencies depending on the project location; the CAISO, and other environmental, land 
management and resource agencies such as the Bureau of Land Management, the U.S. Forest Service, the California 
Department of Fish and Game, and the California Coastal Commission; and regional water quality control boards. In 
addition, to the extent that SCE transmission line projects pass through lands owned or controlled by Native American tribes, 
consent and approval from the affected tribes and the Bureau of Indian Affairs are also necessary for the project to proceed.

Overview of Ratemaking Process

CPUC

Revenue authorized by the CPUC through triennial GRC proceedings is intended to provide SCE a reasonable opportunity to 
recover its costs and earn a return on its net investments in generation and distribution assets and general plant (also referred 
to as "rate base") on a forecast basis. The CPUC sets an annual revenue requirement for the base year which is made up of the 
operation and maintenance costs, depreciation, taxes and a return consistent with the authorized cost of capital (discussed 
below). In the GRC proceedings, the CPUC also generally approves the level of capital spending on a forecast basis. 
Following the base year, the revenue requirements for the remaining two years are set by a methodology established in the 
GRC proceeding, which generally, among other items, includes annual allowances for escalation in operation and 
maintenance costs and additional changes in capital-related investments. The CPUC is conducting a triennial safety model 
assessment proceeding ("S-MAP") to evaluate the utility models used to prioritize safety risks, examine the utilities' 
assessment of their key risks and their proposed mitigation programs, and develop requirements for annual reporting of risk 
spending and mitigation results. The risk assessment approach developed in the S-MAP will be incorporated into SCE's 
triennial GRC through a Risk Assessment and Mitigation Phase (RAMP), which will be initiated by November 15 in the year 
preceding each GRC application filing date. SCE's first RAMP will be filed in November 2018 for its 2021 GRC. The 
purpose of the RAMP is to provide information about the utility's assessment of its key safety risks and its proposed 
programs for mitigating those risks. The information developed during the RAMP will inform the utility's recommended 
projects and funding requests in the subsequent phase of the GRC.

SCE's 2015 GRC authorized revenue requirements for 2016 and 2017 are $5.391 billion, and $5.663 billion, respectively. In 
September 2016, SCE filed its 2018 GRC Application, which covers 2018 – 2020. For further discussion of the 2018 GRC, 
see "Management Overview—Regulatory Proceedings—2018 General Rate Case" in the MD&A.

The CPUC regulates SCE's cost of capital, including its capital structure and authorized rates of return. SCE's authorized 
capital structure is 43% long-term debt, 9% preferred equity and 48% common equity. SCE's currently authorized cost of 
capital consists of: cost of long-term debt of 5.49%, cost of preferred equity of 5.79% and return on common equity of 
10.45%. In February 2017, SCE and the other Investor-Owned Utilities agreed with ORA and TURN to postpone the filing of 
new cost of capital applications from April 2017 to April 2019, reset the respective Investor-Owned Utilities' authorized costs 
of long-term debt and preferred stock, and reduce the Investor-Owned Utilities respective return on common equity, subject 
to CPUC approval. For more information, see "Management Overview—Regulatory Proceedings—Cost of Capital" in the 
MD&A.

SCE's authorized return on investment is established by multiplying an authorized rate of return, determined in separate cost 
of capital proceedings, by SCE's authorized CPUC rate base. 

CPUC 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. Differences between amounts collected and authorized levels are either 
collected from or refunded to customers, and, therefore, such differences do not impact operating revenue. Accordingly, SCE 
is neither benefited nor burdened by the volumetric or price risk related to retail electricity sales.

Cost recovery balancing accounts (also referred to as cost-recovery mechanisms) are used to track and recover SCE's 
decoupled costs of fuel and purchased-power, as well as certain operation and maintenance expenses, including energy 
efficiency and demand-side management program costs. SCE earns no return on these activities and although differences 
between forecasted and actual costs do not impact earnings, such differences do impact cash flows and can change rapidly. 
SCE has other capital-related balancing accounts on which it earns a return, such as the pole loading balancing account.

SCE's balancing account for fuel and power procurement-related costs is referred to as the ERRA. SCE sets rates based on an 
annual forecast of the costs that it expects to incur during the subsequent year. In addition, the CPUC has established a 
"trigger" mechanism for the ERRA. The trigger mechanisms allows for an expeditious rate change if the balancing account 

108

over- or under-collection exceeds 5% of SCE's prior year generation rate revenue. For 2017, the trigger amount is 
approximately $229 million. At December 31, 2016, SCE's overcollection in the ERRA was approximately $20 million, 
which is being refunded to customers in rates beginning on January 1, 2017. 

The majority of procurement-related costs eligible for recovery through cost-recovery rates are pre-approved by the CPUC 
through specific decisions and a procurement plan with predefined standards that establish the eligibility for cost recovery. If 
such costs are subsequently found to be non-compliant with this procurement plan, then this could negatively impact SCE's 
earnings and cash flows. In addition, the CPUC retrospectively reviews outages associated with utility-owned generation and 
SCE's power procurement contract administration activities through the annual ERRA review proceeding. If SCE is found to 
be unreasonable or imprudent with respect to its utility-owned generation outages and contract administration activities, then 
this could negatively impact SCE's earnings and cash flows.

FERC

Transmission capital and operating costs that are prudently incurred, including a return on its net investment in transmission 
assets (also referred to as "rate base"), are recovered through revenues authorized by the FERC. Since 2012, SCE has used a 
formula rate to determine SCE's FERC transmission revenue requirement, including its construction work in progress 
("CWIP") revenue requirement. Under operation of the formula rate, transmission revenue will be updated to actual cost of 
service annually. The transmission revenue requirement and rates are updated each December, to reflect a forecast of costs for 
the upcoming rate period, as well as a true up of the transmission revenue to actual costs incurred by SCE in the prior 
calendar year on its formula rate. The FERC weighted average ROE, including project and other incentives, is comparable to 
the CPUC ROE of 10.45% and can vary based on the mix of project costs that have different incentives. For further 
information on the current FERC formula rates, related transmission revenue requirements and rate changes, see 
"Management Overview—Regulatory Proceedings—FERC Formula Rates" in the MD&A.

Retail Rates Structure and Residential Rate Design

To develop retail rates, the authorized revenue requirements are allocated among all customer classes (residential, 
commercial, industrial, agricultural and street lighting) on a functional basis (i.e., generation, distribution, transmission, etc.). 
Specific rate components are designed to recover the authorized revenue allocated to each customer class. 

SCE has a two-tier residential rate structure with a separate Super User Electric (SUE) surcharge for customers consuming 
more than 400% of average usage. The first tier is priced at below-average cost. The second tier is priced at a higher rate per 
kilowatt hour, and the surcharge rate is set at more than twice the rate of Tier 1. During 2014 – 2015, the CPUC approved 
increases to Tier 1 and 2 rates, permitted reductions over time to the number of tiers, and set a multi-tier road map to smaller 
rate differentials between the tiers. By 2019, the price differential between the first and second tiers will be 25%, with the 
separate SUE surcharge. The CPUC has also ordered a transition beginning in 2019 from tiered to time-of-use (TOU) rates 
for most residential customers unless they opt to stay on the tiered rate structure. The CPUC also permits SCE to recover a 
larger portion of its fixed costs of serving no- or low-usage residential customers through a minimum charge of $10 per 
month minimum bill ($5 for low-income customers) rather than through energy charges that vary with usage. For information 
on residential rates for customers with renewable generation systems, see "—Competition" below.

Energy Efficiency Incentive Mechanism

Prior to September 2013, the mechanism used an incentive calculation that is based on actual energy efficiency expenditures. 
In September 2013, the CPUC adopted an energy efficiency incentive mechanism called the Energy Savings and 
Performance Incentive Mechanism ("ESPI"). The ESPI applies starting with the 2013 – 2014 energy efficiency program cycle 
and continue for subsequent cycles, until further notice. The ESPI is comprised of performance/savings rewards and 
management fees based on actual energy efficiency expenditures and does not contain any provisions for penalties. The 
proposed ESPI schedule anticipates payments of the incentive rewards occurring between one and two years after the relevant 
program year. For further information on the energy efficiency awards, see "Management Overview—Regulatory 
Proceedings—Energy Efficiency Incentive Mechanism" in the MD&A.

Purchased Power and Fuel Supply

SCE obtains the power, energy, and local grid support needed to serve its customers primarily from purchases from external 
parties. Less than 20% of the needed power is provided by SCE's own generating facilities.

109

Natural Gas Supply

SCE requires natural gas to meet contractual obligations for power tolling agreements (power contracts in which SCE has 
agreed to provide or pay for the natural gas used to generate electricity). SCE also requires natural gas to fuel its 
Mountainview and peaker plants, which are generation units that are designed to operate in response to changes in demand 
for power. The physical natural gas purchased by SCE is sourced in competitive interstate markets. SoCalGas provides the  
in-state pipeline transportation service to the gas-fueled generation stations that SCE controls. In 2015 – 2016, SoCalGas 
experienced a significant natural gas fuel leak at its Aliso Canyon underground gas storage facility and the facility has not 
been returned to service. To date, SCE has found that increased gas-use restrictions increased the cost of electricity for 
customers but did not impact grid reliability. There is no certainty that these restrictions will not impact grid reliability in the 
future. However, the price increase would not affect SCE's earnings because decoupled costs of fuel and purchased-power are 
recovered from customers through balancing accounts. For more information on cost-recovery mechanisms, see "—Overview 
of Ratemaking Process" above. SCE is actively monitoring legislative and regulatory processes that are addressing pipeline 
and electric grid operations impacted by the Aliso Canyon leak, including the OII issued by the CPUC in February 2017 to 
consider the feasibility of minimizing or eliminating the use of the Aliso Canyon facility. SCE has also made additional 
procurement efforts to alleviate the impact of the partial closure of Aliso Canyon, including acceleration of existing contracts 
for new capacity, energy storage procurement from third-parties, contracting for design, build, transfer of utility-owned 
storage, additional demand response procurement, and additional energy efficiency procurement.

CAISO Wholesale Energy Market

The CAISO operates a wholesale energy market primarily in California through which competing electricity generators offer 
their electricity output to market participants, including electricity retailers. The CAISO schedules power in hourly 
increments with hourly prices through a day-ahead market in California and schedules power in fifteen-minute and five-
minute increments with fifteen-minute and five-minute prices through two real-time markets that cover California and 
portions of six neighboring states through the Energy Imbalance Market. Both markets optimize energy procurement, 
ancillary service procurement, unit commitment and congestion management. SCE participates in the day-ahead and real-
time markets for the sale of its own generation and generation under contract purchases for its load requirements.

Competition

SCE faces retail competition in the sale of electricity to the extent that federal and California laws permit other entities to 
provide electricity and related services to customers within SCE's service area. While California law provides only limited 
opportunities for customers in SCE's service area to choose to purchase power directly from an energy service provider other 
than SCE, a limited, phased-in expansion of customer choice (direct access) for nonresidential customers was permitted 
beginning in 2009. SCE also faces competition from community choice aggregators ("CCAs"). As of year-end 2016, SCE had 
only one CCA in its service territory (City of Lancaster) but there are several more cities and counties that are exploring the 
possibility of becoming CCAs in SCE's service territory. Competition between SCE and other electricity providers is 
conducted mainly on the basis of price.

SCE also faces increased usage of customer-owned power generation and storage alternatives, such as roof-top solar facilities 
and battery systems, becoming available to its customers as a result of technological developments, federal and state 
subsidies, and declining costs of such alternatives. 

California legislation passed in 1995 encouraged private residential and commercial investment in renewable energy 
resources by requiring SCE to offer a net energy metering ("NEM") billing option to customers who install eligible power 
generation systems to supply all or part of their energy needs. NEM customers are interconnected to SCE's grid and credited 
for the net difference between the electricity SCE supplied to them through the grid and the electricity the customer exported 
to SCE over a twelve month period. SCE is required to credit the NEM customer for most of the power they sell back to SCE 
at the retail rate. Through the credit they receive, NEM customers effectively avoid paying certain grid-related costs. NEM 
customers are also exempted from non-bypassable, standby and departing load charges and interconnection fees.

In January 2016, the CPUC issued a decision implementing AB 327, a rate reform bill enacted in 2013 that instructed the 
CPUC to develop new standard rates for customers with renewable generation systems. The changes that the CPUC decision 
made to the existing NEM tariff do not significantly impact the NEM subsidy. Specifically, the decision requires customers 
that take service on SCE’s NEM tariff after June 2017 to continue to be compensated at the retail rate, minus certain non-
bypassable charges. NEM customers will also continue to be exempted from standby and departing load charges, but will be 
required to pay a $75 interconnection fee and to select a Time-of-Use ("TOU") retail rate. The CPUC will consider making 
additional adjustments to the NEM tariff when it adopts default TOU rates in 2019.

110

The effect of these types of competition on SCE generally is to reduce the amount of electricity purchased by customers. 
However customers, except for NEM customers, who use alternative electricity providers, typically continue to utilize and 
pay for SCE's transmission and distribution services. See "Risk Factors—Risks Relating to Southern California Edison 
Company—Competitive and Market Risks."

In the area of transmission infrastructure, SCE has experienced increased competition from independent transmission 
providers under the FERC's transmission planning requirements rules, effective in 2011, that removed the incumbent public 
utility transmission owners' federally-based right of first refusal to construct certain new transmission facilities and mandated 
regional and interregional transmission planning. Regional entities, such as independent system operators, have processes for 
regional and interregional transmission planning and the competitive solicitation and selection of developers (including 
incumbent utilities) to build and own certain types of new transmission projects. In 2014, the FERC approved the CAISO's 
process for regional planning and competitive solicitations and the CAISO's interregional planning process. The CAISO has 
held competitive solicitations pursuant to these rules and independent service providers were selected. 

Properties

SCE supplies electricity to its customers through extensive transmission and distribution networks. Its transmission facilities, 
which include sub-transmission facilities and are located primarily in California but also in Nevada and Arizona, deliver 
power from generating sources to the distribution network and consist of lines ranging from 33 kV to 500 kV and substations. 
SCE's distribution system, which takes power from substations to customers, includes over 53,000 line miles of overhead 
lines, 38,000 line miles of underground lines and approximately 800 substations, all of which are located in California. SCE 
owns the generating facilities listed in the following table:

1  Pebbly Beach Generating Station consists of 11 MW of diesel generators and liquid petroleum gas micro-turbines supported by 1 MW of 

battery storage capacity.

2  Enhanced peaker plants consist of 98 MW of gas turbine supported by 20 MW of battery storage capacity.

Certain of SCE's substations, and portions of its transmission, distribution and communication systems are located on lands 
owned by the federal, state or local governments under licenses, permits, easements or leases, or on public streets or highways 
pursuant to franchises. Certain of the documents evidencing such rights obligate SCE, under specified circumstances and at its 
expense, to relocate such transmission, distribution, and communication facilities located on lands owned or controlled by 
federal, state, or local governments.

The majority of SCE's hydroelectric plants and related reservoirs are located in whole or in part on U.S.-owned lands and are 
subject to FERC licenses. Slightly over half of these plants have FERC licenses that expire at various times between 2021 and 
2046. FERC licenses impose numerous restrictions and obligations on SCE, including the right of the United States to acquire 
projects upon payment of specified compensation. When existing licenses expire, the FERC has the authority to issue new 
licenses to third parties that have filed competing license applications, but only if their license application is superior to SCE's 

111

 
 
 
and then only upon payment of specified compensation to SCE. New licenses issued to SCE are expected to contain more 
restrictions and obligations than the expired licenses because laws enacted since the existing licenses were issued require the 
FERC to give environmental objectives greater consideration in the licensing process. In addition, SCE expects additional 
opposition to new licenses by environmental stakeholder groups. Substantially all of SCE's properties are subject to the lien of 
a trust indenture securing first and refunding mortgage bonds. See "Notes to Consolidated Financial Statements—Note 5. Debt 
and Credit Agreements."

Seasonality

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

ENVIRONMENTAL REGULATION OF EDISON INTERNATIONAL AND SUBSIDIARIES

Edison International's subsidiaries are subject to regulation by federal, state, and local authorities in the United States relating 
to energy and the environment. These regulations impose restrictions on the operation of existing facilities, as well as the cost 
of mitigating the environmental impacts of past operations. For more information on environmental risks, see "Risk Factors
—Risks Relating to Southern California Edison Company—Environmental Risks."

Edison International and SCE continue to monitor legislative and regulatory developments and to evaluate possible strategies 
to meet the various environmental mandates. Additional information about environmental matters affecting Edison 
International and its subsidiaries, is included in "Notes to Consolidated Financial Statements—Note 11. Commitments and 
Contingencies—Contingencies—Environmental Remediation." 

Greenhouse Gas Regulation

There have been a number of federal and state legislative and regulatory initiatives to reduce GHG emissions. Any climate 
change regulation or other legal obligation that would require substantial reductions in GHG emissions or that would impose 
additional costs or charges for the emission of GHGs could significantly increase the cost of generating electricity from fossil 
fuels, as well as the cost of purchased power. However the same regulations could potentially present opportunities to 
improve SCE's systems to enable the grid's role in the adoption of new energy technologies. These regulations could also 
contribute to the introduction of new types of electric loads as a result of the replacement of fossil fuel use in other sectors of 
the economy by electrification in order to achieve statewide GHG emission reductions.

Federal Legislative/Regulatory Developments 

In August 2015, the US EPA issued final rules governing GHG emission standards for existing fossil-fuel power 
plants. Known as the Clean Power Plan, the rules establish state-specific goals and guidelines for the reduction of GHG 
emissions from existing sources, including heat rate efficiency improvements at coal plants, displacement of coal-fired 
electric generation with increased utilization of natural gas combined cycle unit generation, and expanding deployment of 
renewable resources. The Clean Power Plan requires states to impose standards of performance limits for existing fossil fuel-
fired electric generating units, or equivalent statewide intensity-based or mass-based CO2 binding goals or limits. States were 
required either to submit state plans to the US EPA by the Fall of 2016 identifying how they will comply with the rules, or to 
submit interim plans, along with a request for a two-year extension. Final plans for all states are due by the Fall of 2018. SCE 
is participating in the stakeholder efforts to develop the California state plan. Both the timing and the substance of the Clean 
Power Plan are subject to ongoing judicial challenges and in February 2016, the US Supreme Court blocked the 
implementation of the Clean Power Plan pending the completion of the judicial challenges. This action has delayed the 
imposition of the deadlines for the state plans discussed above. Comments made by the new federal administration indicate 
that further delay, or even full rescission of the Clean Power Plan is likely.  SCE cannot predict the ultimate disposition of the 
challenges to this regulation and therefore, cannot determine any potential compliance costs or market risks associated with 
its possible implementation.  

Since 2010, the US EPA's Final Mandatory GHG Reporting Rule has required all sources within specified categories, 
including electric generation facilities, to monitor emissions, and to submit annual reports to the US EPA by March 31 of 
each year. SCE's 2016 GHG emissions from utility-owned generation are estimated to be approximately 2.0 million metric 
tons. 

Regional Initiatives and State Legislation

Regional initiatives and state legislation also require reductions of GHG emissions and to the extent those requirements are 
more stringent than federal requirements, utilities and generators will likely be required to satisfy the regional and state 
requirements in addition to the federal standards.

112

SCE's operations in California are subject to several laws governing GHG emissions. The first law, the California Global 
Warming Solutions Act of 2006 (also referred to as AB 32), establishes a comprehensive program to reduce GHG emissions. 
AB 32 required the California Air Resources Board ("CARB") to develop regulations that would reduce California's GHG 
emissions to 1990 levels by 2020. The CARB regulations became effective in 2012 and established a California cap-and-
trade program. In the California cap-and-trade program, all covered GHG emitters, including SCE, are subject to a "cap" on 
their emissions designed to encourage entities to reduce emissions from their operations. Covered entities must remit a 
compliance instrument for each ton of carbon dioxide equivalent gas emitted and can do so buying state-issued emission 
allowances at auction or purchasing them in the secondary allowance market. GHG emitters can also meet up to 8% of their 
AB 32 cap-and-trade obligations by participating in verified offset programs, such as reforestation, that have recognized 
effects on reducing atmospheric GHGs.

Subsequently, SB 1368 required the CPUC and the California Energy Commission to adopt GHG emission performance 
standards that apply to California investor-owned and publicly owned utilities' long-term arrangements for the purchase of 
electricity. The standards that have been adopted prohibit these entities, including SCE, from entering into long-term financial 
commitments with generators that emit more than 1,100 pounds of CO2 per megawatt-hour, which is the performance of a 
combined-cycle natural gas turbine generator.

In 2011, California enacted a law to require California retail sellers of electricity to deliver 33% of their customers' electricity 
requirements from renewable resources, as defined in the statute. The CPUC set delivery quantity requirements applicable to 
SCE that incrementally increase to 33% over several periods between January 2011 and December 2020. In October 2015, 
California enacted SB 350, which increases the amount of electricity from renewable resources that California retail sellers 
must deliver after 2020 to 40% of retail sales by December 2024, 45% of retail sales by December 2027, and 50% of retail 
sales by December 2030. 

SCE's delivery of eligible renewable resources to customers was approximately 21% of its total energy portfolio for the 
compliance period 2011 – 2013, which met SCE's goal for that period. SCE expects to meet its compliance goal of 
approximately 23% as weighted for the 2014 – 2016 compliance period.

Most recently, in 2016, California enacted SB 32, which requires the reduction of GHG emissions across the entire California 
economy to 40% below 1990 levels by 2030. Edison International expects this newest law will likely expand the focus of 
reductions from the generation of electricity to other large sources of GHG emissions such as the transportation and industrial 
sectors. Edison International believes that this change in focus will likely lead to increased electrification of these sectors. AB 
197, also enacted in 2016 as a companion bill to SB 32, prioritized direct emission reductions, established joint-legislative 
oversight committee on climate change, and highlighted the increasing California legislative focus on disadvantaged 
community impacts of climate change.

Purchases of Equity Securities by Southern California Edison and Affiliated Purchasers

Information with respect to frequency and amount of cash dividends is included in "Notes to the Consolidated Financial 
Statements—Note 18. Quarterly Financial Data (Unaudited)." As a result of the formation of a holding company described 
under the heading "Business" above, all of the issued and outstanding common stock of SCE is owned by Edison 
International and there is no market for such stock. 

Information on securities authorized for issuance under equity compensation plans, is not applicable because SCE has no 
compensation plans under which equity securities of SCE are authorized for issuance.

The accompanying condensed financial statements of Edison International Parent should be read in conjunction with the 
consolidated financial statements and notes thereto of Edison International and subsidiaries ("Registrant") included in this 
Form 10-K. Edison International's Parent significant accounting policies are consistent with those of the Registrant, SCE and 
other wholly owned and controlled subsidiaries.

Dividends Received

Edison International Parent received cash dividends from SCE of $701 million, $758 million and $378 million in 2016, 2015 
and 2014, respectively.

Dividend Restrictions

The CPUC regulates SCE's capital structure which limits the dividends it may pay Edison International. SCE may make 
distributions to Edison International as long as the common equity component of SCE's capital structure remains at or above 
the 48% on a 13-month weighted average basis. At December 31, 2016, SCE's 13-month weighted-average common equity 
component of total capitalization was 50.4% and the maximum additional dividend that SCE could pay to Edison 
International under this limitation was approximately $585 million, resulting in a restriction on SCE's net assets of 
$13.9 billion.

Note 2.  Debt and Credit Agreements

Long-Term Debt

During the first quarter of 2016, Edison International Parent issued $400 million of 2.95% senior notes due in 2023. The 
proceeds from these bonds were used to repay commercial paper borrowings and for general corporate purposes. In addition, 
at December 31, 2016 and 2015, Edison International Parent had 3.75% senior notes outstanding of $400 million, which 
matures in 2017. 

121

 
 
 
Credit Agreements and Short-Term Debt

During the third quarter of 2016, Edison International Parent amended the credit facility to extend the maturity date for the 
$1.25 billion credit facility to July 2021. At December 31, 2016, the outstanding commercial paper was $538 million at a 
weighted-average interest rate of 0.97%. This short-term debt was supported by the $1.25 billion multi-year revolving credit 
facility. At December 31, 2015, the outstanding commercial paper was $646 million at a weighted-average interest rate of 
0.78%.

The following table summarizes the status of the credit facility at December 31, 2016:

The debt covenant in Edison International's credit facility requires a consolidated debt to total capitalization ratio of less than 
or equal to 0.65 to 1. At December 31, 2016, Edison International's consolidated debt to total capitalization ratio was 0.47 
to 1.

Note 3.  Related-Party Transactions

Edison International's Parent expense from services provided by SCE was $3 million annually in 2016, 2015 and 2014. 
Edison International's Parent interest expense from loans due to affiliates was $3 million in 2016, $6 million in 2015 and 
$1 million in 2014. Edison International Parent had current related-party receivables of $262 million and $252 million and 
current related-party payables of $221 million and $149 million at December 31, 2016 and 2015, respectively. Edison 
International Parent had long-term related-party receivables of $103 million and $105 million at December 31, 2016 and 
2015, respectively, and long-term related-party payables of $243 million and $213 million at December 31, 2016 and 2015, 
respectively.

b  Edison International recorded deferred tax assets of $2.2 billion related to net operating losses and tax carryforwards that pertain to 
Edison International's consolidated or combined federal and state tax returns, including approximately $1.6 billion related to EME. 
Edison International continues to consolidate EME for federal and certain combined state tax returns. EME's Plan of Reorganization, 
filed in December 2013 ("December Plan of Reorganization"), provides for the transfer of EIX's ownership interest to the creditors, 
which would result in a tax deconsolidation of EME. Under federal and state tax regulations, the tax deconsolidation of EME would 
reduce the amounts of net operating loss and tax credits carryforwards that Edison International would be eligible to use in future 
periods. As a result of the EME's December Plan of Reorganization, which would result in a tax deconsolidation of EME, Edison 
International has recorded a $1.380 billion valuation allowance based on the estimated amount of such benefits as calculated under the 
applicable federal and state tax regulations as of December 31, 2013. The deferred income tax benefits recognized by Edison 
International less the valuation allowance for amounts that would no longer be available upon tax deconsolidation of EME was 
approximately $220 million.

c  On April 1, 2014, under the Amended Plan of Reorganization, EME emerged from bankruptcy free of liabilities but remained an 

indirect wholly-owned subsidiary of Edison International, which will continue to be consolidated with Edison International for income 
tax purposes. Edison International anticipates realization of the federal and California tax benefits before they expire. Therefore, the 
valuation allowance on federal and California tax benefits that Edison International recorded in 2013 was released in 2014. The 
remaining valuation allowance is related to non California state tax benefits.

d 

In 2016, Edison International determined that $8 million of the assets subject to a valuation allowance, had no expectation of recovery 
and were written off.

(1) Edison International’s earnings are prepared in accordance with generally accepted accounting principles (GAAP) used in the  
United States. Management uses core earnings and core earnings per share (EPS) internally for financial planning and for analysis  
of performance. Core earnings and core EPS are also used when communicating with analysts and investors regarding our  
earnings results to facilitate comparisons of the Company’s performance from period to period. Core earnings and core EPS are  
non-GAAP financial measures and may not be comparable to those of other companies. Core earnings and core EPS are defined 
as basic earnings and basic EPS excluding income or loss from discontinued operations and income or loss from significant  
discrete items that management does not consider representative of ongoing earnings. Basic earnings refer to net income  
attributable to Edison International shareholders.

(2) Represents year-end rate base at December 31, which includes capital expenditures related to certain FERC-approved  
projects during the construction phase. Capital expenditures for each year include accruals.
