               Note:  All  schedules  other than that listed above have been omitted since the
information is either disclosed elsewhere in the financial statements
or not required by 29 CFR 2520.103-10 of the Department of Labor's
Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974, as amended. Page 2 Report of Independent Registered Public Accounting Firm Southern California Edison Company Benefits Committee Rosemead, California We have audited the accompanying statements of net assets available for plan benefits of the Edison 401(k) Savings Plan (the "Plan") as of December 31, 2005 and 2004, and the related statement of changes in net assets available for plan benefits for the year ended December 31, 2005. These financial statements and the supplemental schedule referred to below are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal controls over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly we express no such opinion. An audit also 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, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits as of December 31, 2005 and 2004, and the changes in net assets available for plan benefits for the year ended December 31, 2005 in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2005 is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ BDO Seidman, LLP ------------------------------- BDO Seidman, LLP Costa Mesa, California May 25, 2006 Page 3 Edison 401(k) Savings Plan Statements of Net Assets Available for Plan Benefits December 31, 2005 2004 ----------------------------------------------------------------------------------------------- (in 000's) Assets Cash $ 9,606 $ 8,267 Investments, at fair value 3,169,411 2,646,106 Receivables Dividends receivable 9,048 7,390 Interest receivable 1,270 569 Profit sharing receivable 4,096 4,309 Receivable from brokers 1,438 5,653 ----------------------------------------------------------------------------------------------- Total receivables 15,852 17,921 ----------------------------------------------------------------------------------------------- Total assets 3,194,869 2,672,294 ----------------------------------------------------------------------------------------------- Liabilities Payable to brokers and others 21,593 16,233 ----------------------------------------------------------------------------------------------- Total liabilities 21,593 16,233 ----------------------------------------------------------------------------------------------- Net assets available for benefits $ 3,173,276 $ 2,656,061 ----------------------------------------------------------------------------------------------- See accompanying notes to financial statements.

Page 5 Edison 401(k) Savings Plan Notes to Financial Statements 1. Plan Description The following description of the Edison 401(k) Savings Plan (the Plan), provides only general information. The Plan sponsor is the Southern California Edison Company (the Plan Sponsor). Participants should refer to the summary plan description and plan document, as amended, for a more complete description of the Plan's provisions. Nature of Plan Eligibility The Plan is a defined-contribution plan with a 401(k) feature, in which qualifying full-time and part-time employees of Edison International (the Company) and many of its subsidiary companies are eligible to participate. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). An employee, as defined by the Plan document, is eligible to participate in the Plan immediately upon employment. Contributions Subject to statutory limits, all participants may defer up to 84 percent of eligible pay. Participating employers provide matching contributions up to 6.0 percent of a participant's eligible pay. Certain participating subsidiaries also provide a fixed profit sharing contribution of 3.0 percent of eligible pay each pay period and a variable profit sharing contribution annually (if certain business objectives are reached) to eligible employees. The Plan also accepts rollover contributions from other qualified plans. Vesting Participants immediately vest in their contributions plus actual earnings thereon. Employer contributions plus actual earnings thereon vest at a rate of 20 percent per year. After five years of service or reaching age 65, all existing and future employer contributions are fully vested. Page 6 Edison 401(k) Savings Plan Notes to Financial Statements (Continued) 1. Plan Description Forfeitures (Continued) At December 31, 2005, and 2004, the unused portion of forfeited non-vested accounts totaled $0 and $6,283, respectively. These accounts are used to reduce future employer contributions. During 2005, employer contributions were reduced by $411,954 from forfeited non-vested accounts. Plan Trust Plan assets are held in trust with State Street Bank and Trust Company (the Trustee) for the benefit of participants and their beneficiaries. The mutual covenants to which the Plan Sponsor and the Trustee agree are disclosed in the trust agreement between the Plan Sponsor and the Trustee. Plan Administration The Plan is administered by the Southern California Edison Company Benefits Committee (the Plan Administrator). Hewitt Associates LLC is the Plan's record keeper. As of December 31, 2005 and 2004, the Plan provided investment choices in 47 and 48 investment funds, respectively. The Plan provides a detailed description of each investment fund choice and lists the respective investment manager. Administrative and Investment Expenses The Plan Sponsor pays the cost of administering the Plan, including fees and expenses of the Trustee and record keeper. The fees, taxes and other expenses incurred by the Trustee or investment managers in making investments are paid out of the applicable fund. This includes brokerage fees for sales or purchases of Edison International Common Stock on the open market. No additional costs are incurred in connection with sales of Edison International Common Stock within the trust or the transfer of assets between funds. Page 7

1.     Plan Description      Mutual   funds   pay  fees  to  the   Plan   record   keeper   for
       (Continued)           administrative  services to participants that would otherwise have
                             to  be  provided  by  the  mutual  funds.  The  majority  of  fees
                             received by the Plan  record  keeper are used to reduce the record
                             keeping  and  communication  expenses  of the Plan.  The return of
                             these   fees   to  the   record   keeper   qualifies   them  as  a
                             party-in-interest  transaction.  See  Note 7 for a  discussion  of
                             related party transactions.

                             Participant Accounts

                             Each  participant   account  is  adjusted  for  the  participant's
                             contribution,  the employer's  contribution,  if  applicable,  and
                             allocations   of   investment   earnings/losses.   Allocation   of
                             earnings/losses  and  expenses  is based on account  balances,  as
                             defined.  The  benefit to which a  participant  is entitled is the
                             benefit  that can be  provided  from  the  vested  portion  of the
                             participant's account.

                             Participant Loans

                             Participants  may borrow from their  account,  a minimum of $1,000
                             to  a  maximum  of  $50,000,  with  certain   restrictions.   Loan
                             transactions  are treated as a transfer  from (to) the  investment
                             fund to (from)  participant  loans.  Loan terms  range from one to
                             four  years for  general  purpose  loans or up to 15 years for the
                             purchase  of a primary  residence.  Loans bear  interest  at prime
                             rate plus one percent.  Interest rates of outstanding  loans range
                             from   5.0 percent  to  10.5 percent  as  of  December  31,  2005.
                             Principal   and  interest  are  paid   ratably   through   payroll
                             deductions.   Some   separated   participants   may   repay   loan
                             obligations  directly,  rather than  through  payroll  deductions.
                             Participant  Loans  amounted  to  approximately   $60,797,000  and
                             $59,099,000 as of December 31, 2005, and 2004, respectively.

1.     Plan Description      Distribution to Participants
       (Continued)
                             Account  balances are  distributed as soon as practicable  after a
                             participant dies,  becomes entitled to a distribution and requests
                             a distribution,  or terminates  employment with an account balance
                             of   $5,000   or   less.    Participants   may   otherwise   delay
                             distribution,  subject to the  minimum  distribution  requirements
                             under Internal  Revenue Code Section  401(a)(9).  Participants may
                             choose a lump sum, partial  distribution or an installment form of
                             payment.   Participants  who  terminate  employment  on  or  after
                             January  28,  2005  with a vested  account  balance  greater  than
                             $1,000  but less than or equal to $5,000  will have  their  vested
                             account   balance   automatically   rolled   over  to   individual
                             retirement  accounts  (IRA)  selected by the Chair or Secretary of
                             the Plan  Administrator,  unless  the  participants  make a timely
                             distribution election.

                             Profit Sharing

                             Certain  non-represented  employees of Edison Mission Group Inc.'s
                             (EMG)  participating  subsidiaries  are  eligible for two types of
                             profit sharing contributions:

                             (i)     Fixed profit  sharing is comprised of a 3.0 percent profit
                                     sharing  contribution  each  pay  period  to the  Plan  on
                                     behalf  of  eligible   employees.   Fixed  profit  sharing
                                     contributions in 2005 amounted to $2,017,778.

                             (ii)    Variable  profit  sharing is  comprised  of an  additional
                                     annual profit sharing  contribution  to the Plan on behalf
                                     of eligible  employees if certain business  objectives are
                                     reached.  Variable  profit  sharing  contribution  made in
                                     2006 for the 2005 plan year were  6.25% for  eligible  EMG
                                     employees  for a total amount of  $4,095,761.  Such amount
                                     is  presented  as  "Profit  sharing   receivable"  on  the
                                     Statement of Net Assets  Available for Plan Benefits as of
                                     December 31, 2005.

       Policies              accounting and in conformity with accounting  principles generally
                             accepted in the United  States of America  applicable  to employee

                             America  requires  management to make  estimates  and  assumptions
                             that  affect the  reported  amounts of  assets,  liabilities,  and
                             changes   therein,   and  disclosure  of  contingent   assets  and

2.     Summary of            The  Plan  provides  for  various   funds  that  hold   investment
       Significant           securities.  Investment  securities  are exposed to various  risks
       Accounting            such as interest rate,  market,  and credit risk. Due to the level
       Policies              of risk  associated  with certain  investment  securities  and the
       (Continued)           level  of   uncertainty   related  to  changes  in  the  value  of
                             investment  securities,  it is at least  reasonably  possible that
                             changes  in  risk  in  the  near  term  would  materially   affect
                             participants'   account  balances  and  the  amounts  reported  in
                             Statements  of Net  Assets  Available  for Plan  Benefits  and the
                             Statement of Changes in Net Assets Available for Plan Benefits.

                             The Plan participates in various  investment options that comprise
                             securities of foreign  companies,  which involve special risks and
                             considerations  not typically  associated  with  investing in U.S.
                             companies.  These risks include  devaluation of  currencies,  less
                             reliable   information   about   issuers,   different   securities
                             transaction  clearance  and  settlement  practices,  and  possible
                             adverse   political   and   economic    developments.    Moreover,
                             securities  of many  foreign  companies  and their  markets may be
                             less liquid and their  prices more  volatile  than  securities  of
                             comparable U.S companies.

                             Investment Valuation and Income Recognition

                             The Plan's  investments are stated at fair value or estimated fair
                             value.  Investments  in  mutual  funds  valued  at  quoted  market
                             prices  represent units held by the Plan at year end.  Investments
                             in the common  collective funds invest in premixed  portfolios and
                             institutional  funds  (see  Note  4).  Investments  in the  common
                             collective  funds are valued at net asset  value of shares held by
                             the  Plan  at  year-end.  Edison  International  Common  Stock  is
                             valued at its quoted  market price.  Participant  loans are valued
                             at cost,  which  approximates  fair value.  Purchases and sales of
                             securities  are recorded on a trade-date  basis.  Interest  income
                             is recorded on the accrual  basis.  Dividends  are recorded on the
                             ex-dividend date.

 2.    Summary of            Participant  loans  that are in default  as  provided  in the plan
       Significant           document,  are treated as deemed  distributions  for tax  purposes
       Accounting            and  also  reported  as  such in the  Form  5500.  Management  has
       Policies              determined these loans in default as  uncollectible.  For the year
       (Continued)           ended December 31, 2005,  $103,003 of participant loans in default
                             were deemed to be uncollectible and written-off.  This is included
                             as loans in  default  in the  Statement  of  Changes in Net Assets
                             Available for Plan Benefits.

                             Net Appreciation (Depreciation) in Fair Value of Investments

                             Realized and unrealized  appreciation  (depreciation)  in the fair
                             value of investments  is based on the difference  between the fair
                             value of the assets at the  beginning of the year,  or at the time
                             of purchase for assets  purchased during the year, and the related
                             fair  value  on the day  investments  are  sold  with  respect  to
                             realized  appreciation  (depreciation),  or on the last day of the
                             year for unrealized appreciation (depreciation).

                             Distributions to Participants

                             Distributions  to  participants,  other than loans,  are  recorded
                             when paid.


3.     Investment            The Trustee invests  contributions  in accordance with participant
       Elections             instructions.

                             Participants  may elect changes to their  investment mix effective
                             each business day, with certain  restrictions.  The Plan imposes a
                             seven-day  trading  restriction for most participants that applies
                             to  all  funds  except  the  Edison   International   Stock  Fund.
                             Reallocation   elections   are  also   subject   to  any   trading
                             restrictions,  redemption  fees,  or  other  measures  imposed  by
                             investment  fund  managers.  Participants  may  effect  changes to
                             their  deferral  percentages  and  deferral  investment  elections
                             coincident with their pay frequency.

                             party-in-interest   transactions.   Fees  earned  by  State  Street

                             record keeper were  $1,214,795 for 2005 and were used to reduce the
                             recordkeeping  and  communication  expenses of the Plan incurred by
                             the Plan Sponsor.

8.     Plan                  Although  it has not  expressed  intent to do so, the Plan Sponsor

                             any time and to  terminate  the Plan subject to the  provisions  of
                             ERISA. In the event of Plan  termination,  participants will become
                             fully  vested in their  accounts.  The Trust  will  continue  after
                             termination  until  all  Trust  assets  have  been  distributed  to
                             participants and their beneficiaries.

9.     Tax Status            The Internal  Revenue  Service has determined and informed the Plan
                             Sponsor by a letter dated May 22,  2002,  that the Plan and related
                             trust as  amended  through  November  29,  2001,  are  designed  in
                             accordance  with  the  applicable  qualification  sections  of  the
                             Internal  Revenue  Code  (IRC).  The Plan has  been  amended  since
                             receiving   the   determination    letter.    However,   the   Plan
                             Administrator  believes that the Plan,  as amended,  is designed in
                             compliance  with the applicable  qualification  requirements of the
                             IRC.  In  addition,  the  Plan  Administrator  is not  aware of any
                             operational  issues  that  will  prevent  the  continuation  of the
                             Plan's qualified tax status.
