To the Participants and Administrator of
AT&T Long Term Savings and Security Plan



In our opinion, the accompanying statements of net assets available for benefits
and the  related  statement  of changes in  net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of AT&T Long Term Savings  Plan and  Security  Plan (the "Plan") at December 31,
2003 and 2002, and the changes in net assets available for benefits for the year
ended  December 31, 2003 in  conformity  with  accounting  principles  generally
accepted in the United States of America.  These  financial  statements  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 of these  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.

Our audits  were  conducted  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,  2003 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 is the  responsibility  of the
Plan's management.  The supplemental schedule has been subjected to the auditing
procedures  applied in the 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.

AT&T Long Term Savings and Security Plan
Notes to Financial Statements
December 31, 2003
--------------------------------------------------------------------------------

1.   Plan Description

     The AT&T Long Term Savings and  Security  Plan (the "Plan" or "LTSSP") is a
     defined  contribution plan established by AT&T Corp.  ("AT&T") to provide a
     convenient way for occupational  employees of participating  AT&T companies
     to save on a regular  and  long-term  basis.  The LTSSP  participates  in a
     master trust (the "Group Trust") for the investment of the pooled assets of
     various funds.  Each  participating  plan has an undivided  interest in the
     Group Trust.

     An eligible  employee enters the Plan by authorizing a payroll allotment to
     invest his/her  contributions  in one or more of twenty-six  (26) different
     funds as set forth in the current Plan documents.

     The AT&T  Wireless  Stock  Fund  and the  Liberty  Media  Stock  Fund  were
     liquidated as of January 2003 and February 2003, respectively. Any balances
     remaining in these funds at the  liquidation  date were  transferred to the
     AT&T Stable Value Fund.

     On November 18, 2002, AT&T spun-off AT&T Broadband to AT&T  shareholders of
     record as of  November  15,  2002.  Immediately  after the  spin-off,  AT&T
     Broadband  combined  with the Comcast  Corporation.  For each share of AT&T
     Corp.  common  stock,   shareholders   received  .3235  shares  of  Comcast
     Corporation Class A common stock as of the close on November 15, 2002. As a
     result, a Comcast Stock Fund was added to the Group Trust in November 2002.
     The  Comcast  Stock  Fund is not an  employer  security  and is  frozen  to
     employee contributions.

     Employee  allotments of 2% to 16% of salary may be authorized.  An employee
     may designate allotments as pre-tax allotments,  as after-tax allotments or
     as a  combination  of pre-tax and  after-tax  allotments.  All  participant
     contributions  and earnings thereon are immediately  vested and not subject
     to forfeiture. Pre-tax contributions may be made up to the Internal Revenue
     Service limit of $12,000 in 2003. After one year of service,  the employing
     company  (AT&T or any  AT&T  subsidiary  participating  in the  Plan)  will
     contribute  an amount equal to 66-2/3% of the first six percent (6%) of the
     employee's  salary  contributed.  A participant  becomes 100% vested in the
     employing  company  contributions  after three  years of credited  service.
     Company contributions are made in accordance with the participants' elected
     investment direction. The Plan provides that Company Matching Contributions
     associated   with  a  participant's   contribution  to  the   International
     Brotherhood  of Electrical  Workers (IBEW)  Sponsored  Trust for Savings be
     invested  in the AT&T Stock  Fund and then are  immediately  available  for
     participant redistribution.

     Employees  who  are age 50 or  older  on or  before  December  31st  may be
     eligible to make pre-tax  contributions beyond the Internal Revenue Service
     pre-tax  limit.  The 2003 catch-up  contribution  limit set by the Internal
     Revenue  Service is $2,000.  No company  matching  contribution  is made on
     catch-up contributions.



     Loans are available to all  participants in an amount not less than $1,000,
     up to a maximum of the lesser of $50,000  minus the  participant's  highest
     outstanding  loan  balance  in the last  twelve  (12)  months or 50% of the
     employee's   vested  account  balance.   Upon  default,   participants  are
     considered to have received a distribution  and are subject to income taxes
     on the distributed  amount.  Loan transactions are treated as a transfer to
     (from) the investment fund from (to) the Loan Account. The term of the loan
     shall not exceed fifty-six (56) months. The loans are collateralized by the
     balance in the participant's account and bear interest at the prime rate on
     the last  business day of the month  preceding  the month in which the loan
     was initiated.  Interest rates are fixed for the term of the loan. Interest
     rates on participant  loans  outstanding as of December 31, 2003 range from
     4.0 percent to 9.5 percent. Principal and interest are paid through payroll
     deductions or participant-initiated payments.

     When a participant  terminates  employment,  a single  distribution will be
     made of all vested amounts in the participant's account if the amount to be
     distributed  is $5,000 or less.  However,  if the amount to be  distributed
     exceeds $5,000, and the participant does not request the distribution,  the
     participant's  account  shall  remain in the Plan and may be  withdrawn  or
     distributed  at  the   participant's   request,   or  as  minimum  required
     distributions  beginning when the participant  attains age 70-1/2,  or upon
     the participant's death, whichever is earlier.

     Participant   forfeitures  in  2003  were  $362,695.  The  total  forfeited
     non-vested  accounts as of December 31, 2003 is $664,665.  Forfeitures will
     be  used  to  reduce  future  employer   contributions  and  administrative
     expenses.  During 2003, employer  contributions were reduced by $101 due to
     forfeited non-vested accounts.

     For a complete  description of the Plan,  participants  should refer to the
     Plan  Prospectus  and Plan  Summary  Plan  Description  (SPD).  The Plan is
     subject to the provisions of the Employee Retirement Income Security Act of
     1974 ("ERISA").

2.   Accounting Policies

     Basis of Accounting
     The financial statements of the Plan are prepared under  the accrual method
     of accounting.

     Payment of Benefits
     Benefits are recorded when paid.

     Valuation of Investments
     Income and  assets of the Group  Trust are  allocated  to the Plan based on
     participant balances.  The net asset value of the Group Trust is calculated
     by the Trustee.  The trustee  determines the value of the underlying assets
     in the investment manager  portfolios,  taking into account values supplied
     by  a  generally  accepted  pricing  or  quotation  service  or  quotations
     furnished by one or more  reputable  sources,  such as securities  brokers,
     dealers  or  investment  bankers,  mutual  fund  administrators,  values of
     comparable property, appraisals or other relevant information.  Investments
     in AT&T  common  shares  and  other  securities  listed on  national  stock
     exchanges  are  carried at fair value  determined  on the basis of the last
     published  sales  price  per  share on the last  business  day of the year.
     Securities  traded in  over-the-counter  markets  are carried at fair value
     based on the last bid prices or closing prices on December 31, as listed in
     published  sources if available  or, if not  available,  from other sources
     considered  reliable.  Contracts  with  insurance  companies  and financial
     institutions,  which are fully benefit responsive,  are carried at contract
     value (representing contributions made under the contracts plus accumulated
     interest at the contract rates).  All other  investments are carried at the
     fair value at the close of  business  on  December  31.  Participant  loans
     receivable are valued at cost which  approximates  fair value.  Participant
     loans are not part of the Group Trust.

     Purchases and Sales of Investments
     Purchases and sales of securities are recorded as of the trade date.

     Investment Income
     Dividend  income is recorded on the  ex-dividend  date.  Interest income is
     accrued as earned.

     Net Appreciation (Depreciation) in the Fair Value of Investments
     The Plan presents in the  statement of changes in net assets  available for
     benefits  the  net  appreciation   (depreciation)  in  the  fair  value  of
     investments,   which  consist  of  the  realized  gains  (losses)  and  the
     unrealized appreciation (depreciation) on those investments.

     Use of Estimates
     The  preparation  of financial  statements  in  conformity  with  generally
     accepted  accounting  principles  requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities, and
     changes  therein,  and  disclosure  of contingent  assets and  liabilities.
     Actual  results  could differ from those  estimates.  The most  significant
     estimates relate to the valuation of the investments.

     Risks and Uncertainties
     Investments  held by the Group  Trust and the Plan are  exposed  to various
     risks, such as interest rate,  market and credit.  Due to the level of risk
     associated with certain investment  securities and the level of uncertainty
     related to changes in the value of  investment  securities,  it is at least
     reasonably  possible that changes in the near term could materially  affect
     participants'  future  account  balances  and the  amounts  reported in the
     statement of net assets available for benefits and the statement of changes
     in net assets available for benefits.

     Certain  amounts in prior periods have been  reclassified to conform to the
     current presentation.

3.   Tax Status

     The Internal  Revenue  Service (IRS) has  determined and informed AT&T by a
     letter  dated  December  19,  1995,  that the Plan and  related  trust  are
     qualified in accordance  with applicable  sections of the Internal  Revenue
     Code (IRC).  The Plan has been amended and  restated  since  receiving  the
     determination  letter.  The Company  has  applied  for a new  determination
     letter  from  the IRS on  February  28,  2002,  and  the  IRS is  currently
     reviewing the request.  However,  the Plan Administrator  believes that the
     Plan is qualified and is currently  being  operated in compliance  with the
     applicable requirements of the IRC.

4.   Concentrations of Investment Risk

     At December 31, 2003, Plan participants'  accounts that are invested in the
     investment  options  mentioned  herein,  were exposed to market risk in the
     event of a  significant  decline in the value of AT&T Corp.  stock,  and/or
     Comcast stock.

5.   Plan Termination

     Although it has not expressed any intent to do so, AT&T 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,
     the  Plan  provides  that  the  net  assets  are  to  be   distributed   to
     participating  employees in amounts equal to their  respective  interest in
     such assets.

6.   Plan Expenses

     In  general,  fees paid for Plan  administration,  including  recordkeeping
     (except  for such  services as are  attributable  to the  participant  loan
     program),  are paid from the trust,  unless those  expenses are paid by the
     Company or participant(s).  Fees for trustee services are paid out of trust
     assets.  Expenses  attributable to the management and investment of each of
     the investment options shall be charged against respective options.

7.   Group Trust Investments

     The following  table  presents the  investments  in the Group Trust held by
     Fidelity Management Trust Company ("FMTC") as Trustee, at December 31, 2003
     and 2002 (in thousands of dollars except for percentages).

8.   Related Party Transactions and Party-in-Interest

     Certain Plan  investments are in shares of mutual funds managed by Fidelity
     Management and Research  (FMR),  the parent of FMTC. FMTC is the trustee of
     the Plan and, therefore,  these transactions  qualify as  party-in-interest
     transaction.  At December 31, 2003 the total of these investments  amounted
     to $1,914,936,504 or approximately 23% of the Group Trust.

     In addition,  the Plan invests in common shares of AT&T Corp. stock,  which
     qualifies as a related party transaction. At December 31, 2003 the total of
     these investments amounted to $256,799,741 or approximately 3% of the Group
     Trust.

9.   Subsequent Events

     1)  Effective January 2, 2004, State Street Bank and Trust Company was
         appointed as the Trustee to the Plan.
     2)  The Group Trust has been renamed the AT&T Savings Master Trust.
     3)  The Comcast Stock Fund was liquidated in May 2004.  Balances remaining
         in these funds as of the liquidation date were transferred into the
         AT&T Stable Value Fund.
