             Report of Independent Registered Public Accounting Firm



To the Participants and Administrator of
AT&T of Puerto Rico, Inc. Long Term Savings Plan for Management Employees



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 of Puerto Rico,  Inc.  Long Term Savings Plan for  Management  Employees
(the  "Plan") as of 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 of Puerto Rico, Inc. Long Term Savings Plan
for Management Employees
Notes to Financial Statements
December 31, 2003
--------------------------------------------------------------------------------


1.   Plan Description

     The AT&T of  Puerto  Rico,  Inc.  Long  Term  Savings  Plan for  Management
     Employees  (the  "Plan"  or  "PRLTSPME")  is a  defined  contribution  plan
     established  by  AT&T  Corp.  ("AT&T")  to  provide  a  convenient  way for
     management employees (i.e.,  employees whose pay is defined at a monthly or
     annual  rate  and  whose  positions  are  not  subject  to  automatic  wage
     progression)  of AT&T of  Puerto  Rico,  Inc.  to  save  on a  regular  and
     long-term  basis.  The PRLTSPME  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  the  twenty-six  (26)
     different funds as set forth in the current Plan document.

     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 or after-tax allotments. All
     participant  contributions and earnings thereon are immediately  vested and
     are not subject to forfeiture.  Pre-tax contributions may be made up to the
     Puerto  Rico  Department  of  Treasury  limit  of  $8,000  or  10%  of  the
     participants annual compensation,  whichever is less, in 2003.  Immediately
     upon  enrollment,  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  6% of the  employee's  salary  contributed.  Employing  company
     contributions  are  made  in  accordance  with  the  participant's  elected
     investment direction.  Employing company contributions and earnings thereon
     are vested after three years of credited service.

     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
     participant's   vested  account  balance.   Upon  default,   employees  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  funds from (to) the  Participant  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 the loan was taken.  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,  the entire vested amount in the
     participant's  account  will be  distributed  in a single  payment,  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.  When a participant
     dies, the participant's  beneficiary or beneficiaries may elect their share
     of the  participant's  account balance as a single payment or as a transfer
     to a PRLTSPME account in the beneficiary's name.

     Participant forfeitures in 2003 were $8,972. The total forfeited non-vested
     account as of December  31, 2003 is  $38,677.  Forfeitures  will be used to
     reduce future employer contributions.  During 2003 there were no reductions
     in employer contributions 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 on 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  consists  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.

     Risk and Uncertainties
     Investments  held by the Group Trust 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 Puerto Rico  Department of Treasury has determined and informed AT&T by
     letter dated May 31, 1995, that the Plan and related trust are qualified in
     accordance  with  applicable  sections of the Puerto Rico Income Tax Act of
     1954  (the  "Act").   The  Plan  has  been  amended  since   receiving  the
     determination  letter. The Plan Administrator,  however,  believes that the
     Plan is qualified and is currently  being  operated in compliance  with the
     applicable requirements of the Act.

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

     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.

     The Group Trust has been renamed the AT&T Savings Master Trust.
