                        Report of Independent Accountants


To the Participants and Administrator of the
AT&T of Puerto Rico, Inc. 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 the AT&T of Puerto Rico, Inc. Long Term Savings and Security Plan (the
"Plan") as of December 31, 2002 and 2001, and the changes in net assets
available for plan benefits for the year ended December 31, 2002 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
auditing standards generally accepted in the United States of America, which
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 the 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) 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 and Security Plan
Notes to Financial Statements
For the Year Ended December 31, 2002 and 2001
--------------------------------------------------------------------------------

1.       Plan Description

         The AT&T of Puerto Rico, Inc. Long Term Savings and Security Plan (the
         "Plan" or "PRLTSSP") is a defined contribution plan established by AT&T
         Corp. ("AT&T") to provide a convenient way for non-management employees
         (i.e., employees who are not a salaried management employee and whose
         positions are subject to automatic wage progression) to save on a
         regular and long-term basis. The PRLTSSP 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 their contributions in one or more of the twenty-six (26)
         different funds, in 10% increments. In 2001, the AT&T Wireless Stock
         Fund and the Liberty Media Stock Fund were no longer employer
         securities and were frozen for additional employee contributions.

         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.

         Other receivable line item on the statement of net assets available for
         benefits relates to securities sold for which cash has not been
         received.

         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 in 2002. After one year of service, the employing
         company (AT&T or any subsidiary of AT&T participating in the Plan) will
         contribute an amount equal to 66-2/3% of the first 6% of the employee's
         salary allotment. Employing company contributions are made in
         accordance with the participant's elected investment direction.
         Employing company contributions and earnings thereon are vested after
         five 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, 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 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 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, 2002 range from 4.25 percent to 9.50 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 or in
         annual retiree withdrawals, as directed by the participant, if the
         amount to be distributed is less than $5,000. 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 distributed at the participant's request, or as minimum required
         distributions 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
         PRLTSSP account in their own name.

         Participant forfeitures in 2002 were $1,211. The total forfeited
         non-vested account as of December 31, 2002 is $4,085. This account will
         be used to reduce future employer contributions. During 2002, 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. The Plan is subject to the provisions of the
         Employee Retirement Income Savings 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
         December 31, or, if no sales were made on that date, at the last
         published sales price on the next preceding day on which sales were
         made. 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 dates.



         Investment income
         Dividend income is recorded on securities held as of the ex-dividend
         dates. Interest income is recorded on the accrual basis.

         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.

         Risks 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 risks in the near
         term would materially affect participants' 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.

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
         designed 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 designed and is currently being operated in
         compliance with the applicable requirements of the Act.

4.       Concentrations of Investment Risk

         At December 31, 2002, Plan participants' accounts, which 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,
         Liberty Media stock, AT&T Wireless 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

         Plan participants share the recordkeeping, accounting, and other
         administrative costs of the Plan with the employing company. Brokerage,
         investment manager and trustee fees are paid by the Plan, and are
         primarily reflected in the calculation of a fund's net asset value per
         unit.

7.       Group Trust Investments

         The following table presents the investments in the Group Trust held by
         Fidelity Management Trust Company ("FMTC") at December 31, 2002 and

8.       Related Party Transactions and Party-in-Interest

         Certain Plan investments are shares of mutual funds managed by Fidelity
         Management and Research (FMR), the parent of FMTC. FMTC is the trustee
         as defined by the Plan and, therefore, these transactions qualify as
         party-in-interest.

         In addition, the Plan invests in common shares of AT&T Corp. Stock,
         which qualifies as a related party transaction. AT&T Wireless Stock and
         Liberty Media Stock qualified as related party transactions until AT&T
         Wireless Services, Inc. and Liberty Media Corporation split-off from
         AT&T Corp. on July 9, 2001 and August 10, 2001, respectively.

9.       Subsequent Events

         Effective January 1, 2003, the vesting period in employing company
         contributions for all participants will change from 100% vested after 5
         years of service to 100% after 3 years of service.

         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.
