                        Report of Independent Accountants


To the Participants and Administrator of the
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 the AT&T Long Term Savings and Security Plan ("the Plan") as of December 31,
2002 and 2001, and the changes in net assets available for 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 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) 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
For the Year Ended December 31, 2002 and 2001

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 non-management employees (i.e., employees
        who are not salaried management employees and whose positions are
        subject to automatic wage progression) 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.

        Prior to 2002, the Plan held assets of the Leveraged ESOP outside the
        Group Trust. In February 2002, these assets of $117 million moved into
        the Group Trust.

        An eligible employee enters the Plan by authorizing a payroll allotment
        to invest their contributions in one or more of 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, 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 $11,000 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 employee's basic allotment up to the first six percent (6%) of
        salary. 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.

        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 prime rate determined monthly by the Plan administrator.
        Interest rates are fixed for the term of the loan. Interest rates



AT&T Long Term Savings and Security Plan
Notes to Financial Statements
For the Year Ended December 31, 2002 and 2001

        on participant loans outstanding as of December 31, 2002 range from 4.25
        percent to 10 percent. Principal and interest are paid through payroll
        deductions or participant-initiated payments.

        The Plan allows participants to direct the investment of Company
        Matching Contributions, and to diversify the amounts held in the
        Employer Shares Fund. Thereafter, all Employer Matching Contributions
        shall be made in cash. Such contributions shall be transferred to the
        Trustee and invested by the Trustee in investment options designated by
        the participant. A participant may change the allocation of existing
        accounts by transferring the portion relating to the Company Matching
        Contribution account in increments of 5% of the participant's balance in
        a fund to another fund. A participant becomes 100 percent vested in the
        employing company contributions after five years of credited service.

        When a participant retires with eligibility for retirement related
        benefits from the AT&T Pension Plan or terminates employment because of
        disability, the entire amount in the participant's account will be
        distributed, at the participant's election, in a single payment or in an
        annual retiree withdrawal of at least $500 per calendar year as directed
        by the participant. If no distribution election is made by the
        participant, the balance in the account will remain in the Plan until a
        later date but not beyond age 70-1/2 when minimum required distributions
        will begin. 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 an LTSSP account in their own
        name.

        In case of other termination of employment (when the participant is not
        entitled to retire on immediate pension or does not terminate because of
        disability), a single distribution will be made of all vested amounts in
        the participant's account 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.

        Participant forfeitures in 2002 were $198,847. The total forfeited
        non-vested accounts as of December 31, 2002 is $269,104. These accounts
        will be used to reduce future employer contributions and administrative
        expenses. During 2002, employer contributions were reduced by $981,975
        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 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



AT&T Long Term Savings and Security Plan
Notes to Financial Statements
For the Year Ended December 31, 2002 and 2001

        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 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 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 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 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.



AT&T Long Term Savings and Security Plan
Notes to Financial Statements
For the Year Ended December 31, 2002 and 2001

3.      Tax Status

        The Internal Revenue Service has determined and informed AT&T by a
        letter dated December 19, 1995, that the Plan and related trust are
        designed in accordance with applicable sections of the Internal Revenue
        Code (IRS). The Plan has been amended since receiving the determination
        letter. Although the Company has requested an update to the
        determination letter from the IRS on February 28, 2002, a response has
        not yet been received. However, the Plan administrator believes that the
        Plan is designed and is currently being operated in compliance with the
        applicable requirements of the IRC.

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.

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 a 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.
