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,  2006 and 2005,  and the  related  statement  of changes in net
assets  available for plan benefits for the year ended December 31, 2006.  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, 2006 and 2005,  and the changes in net assets  available
for plan  benefits for the year ended  December 31, 2006 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,  2006 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.

                                      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

                                      immediately upon employment.

                                      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.

        (Continued)

                                      At  December 31,  2006, and 2005, the unused  portion of forfeited  non-vested  accounts
                                      totaled $9,928 and $0,  respectively.  These accounts are used to reduce future employer
                                      contributions.  During  2006,  employer  contributions  were  reduced by  $421,033  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,  2006 and 2005,  the Plan  provided  investment  choices  in 47  investment
                                      funds.  The Plan  provides to participants 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
                                      investment  funds.  These expenses also include 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.

1.        Plan Description     Mutual  funds  pay  fees to the  Plan  record  keeper  for  administrative  services  to
          (Continued)          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 paid by the Plan  Sponsor.  See Note 7
                                      for a discussion of party-in-interest 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.  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 on
                                      outstanding  loans range from  5.0 percent  to  10.5 percent  as of December  31,  2006.
                                      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  $61,821,000 and $60,797,000 as
                                      of December 31, 2006, and 2005, 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 2006 amounted to $2,195,506.

                                      (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  contributions made in 2007 for
                                              the 2006 plan year were 5.50% of eligible  earnings for  eligible EMG  employees
                                              for a total amount of  $3,936,953.  Such amount is presented as "Profit  sharing
                                              receivable"  on the  Statement of Net Assets  Available  for Plan Benefits as of
                                              December 31, 2006.

2.   Summary of Significant        Basis of Accounting
        Accounting
        Policies               The  financial  statements  are  presented  on the accrual  basis of  accounting  and in
                                      conformity  with  accounting  principles  generally  accepted  in the  United  States of
                                      America (U.S.A.) applicable to employee benefit plans and ERISA.

                                      Use of Estimates

                                      The  preparation  of financial  statements  in  conformity  with  accounting  principles
                                      generally  accepted  in the  United  States  of  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  liabilities.  Actual results
                                      could differ materially from those estimates.

                                      Risks and Uncertainties

                                      The Plan's  investment in Edison  International  common stock amounted to  approximately
                                      $1,066,948,000  and  $1,324,221,000  as of December  31, 2006,  and 2005,  respectively.
                                      Such  investments  represented  approximately  31  percent  and 41 percent of the Plan's
                                      total  assets  as  of  December  31,  2006,  and  2005,  respectively.   For  risks  and
                                      uncertainties  regarding  investment in the Company's common stock,  participants should
                                      refer to the Annual report on Form 10-K for the period ended  December 31, 2006, and the

                                                                         Notes to Financial Statements (Continued)




2.      Summary of Significant    The Plan  provides  for  various  funds  that  hold  investment  securities.  Investment
        Accounting             securities  are  exposed to various  risks such as  interest  rate,  market,  and credit
        Policies               risk. Due to the level 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.A.  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.A. 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 at year-end.  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

                                                                      Notes to Financial Statements (Continued)




7.      Party-In-Interest         The Plan's  investment  options include the Company's  Common Stock as a fund option.  See
        Transactions           Note 2 for a discussion of the amount of the Plan's  investment  in the  Company's  Common
        Continued(             Stock. In addition,  State Street Global  Advisors,  an affiliate of State Street Bank and
                                      Trust Company,  is the investment manager of the Edison  International  Common Stock Fund.
                                      Fees earned by State Street Global  Advisors in its capacity as the investment  manager of
                                      the Edison  International  Common Stock Fund were $120,840 for 2006 and were reported as

                                      Plan Benefits.

                                      Fees paid by the Plan Sponsor for  administrative  and other services rendered to the Plan
                                      were based on customary  and  reasonable  rates for such  services.  Various  mutual funds
                                      offered  as  investment  options in the Plan  transfer  to Hewitt  Associates,  the Plan's

                                      to Plan  participants  who invest in the mutual funds  (these  shareholder  servicing  and
                                      distribution  service  fees are  charged  to all  investors  in the mutual  funds).  These
                                      transferred  fees,  which  totaled  $1,500,748  for  2006,  were  used  to  reduce  Hewitt
                                      Associates'  charge to the Plan Sponsor for  services  Hewitt  Associates  provided to the
                                      Plan.

                                      See  Note  1 for a  discussion  of the  Plan's  loans  to  participants  and  Note 2 for a
                                      discussion of the participant loans in default

8.      Plan Termination       Although it has not  expressed  intent to do so, the Plan  Sponsor has the right under the
                                      Plan to  discontinue  its  contributions  at 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

                                                                      Notes to Financial Statements (Continued)




                                      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.

10.     Employee Stock         The Edison  International  Common Stock Fund  constitutes an employee stock ownership plan
        Ownership Plan         that  allows  for  the  current  distribution  of  dividends  to  all  participants.  Such

                                      21, 2006, the board of directors of Edison International  declared a common stock dividend
                                      of $0.29 per share  payable on  January  31,  2007,  to the  shareholders  of record as of
                                      December  30,  2006.  As the  record  date was at year end,  dividend  income of $0.29 per
                                      share  amounting to  $6,758,834  was accrued and included in dividends  receivable  in the
