                          INDEPENDENT AUDITORS' REPORT


The Plan Committee
Liberty Media 401(k) Savings Plan:


We have audited the accompanying statements of net assets available for
participant benefits of the Liberty Media 401(k) Savings Plan (the "Plan") as of
December 31, 2001 and 2000, and the related statements of changes in net assets
available for participant benefits for the years then ended. 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 in accordance with auditing standards generally accepted
in the United States of America. 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. An audit also includes 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 participant benefits of the
Plan as of December 31, 2001 and 2000, and the changes in net assets available
for participant benefits for the years then ended 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 schedules of assets
held at end of year, nonexempt transactions, and reportable transactions are
presented for the purpose of additional analysis and are not a required part
of the basic financial statements but are 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. These
supplemental schedules are the responsibility of the Plan's management. The
supplemental schedules have been subjected to the auditing procedures applied
in the audit of the basic financial statements and, in our opinion, are
fairly stated in all material respects in relation to the basic financial
statements taken as a whole.

                          Notes to Financial Statements

                           December 31, 2001 and 2000

(1)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF PRESENTATION

         The accompanying financial statements of the Liberty Media 401(k)
         Savings Plan (the "Liberty Plan") have been prepared on the accrual
         basis and present the net assets available for participant benefits and
         the changes in those net assets. The sponsor of the Liberty Plan is
         Liberty Media Corporation ("Liberty"). From March 9, 1999 through
         August 9, 2001, Liberty was a wholly-owned subsidiary of AT&T Corp.
         ("AT&T"). Effective August 10, 2001, AT&T effected the split-off (the
         "Split Off") of Liberty pursuant to which Liberty's common stock was
         recapitalized, and each outstanding share of AT&T Class A Liberty Media
         Group common stock and AT&T Class B Liberty Media Group common stock
         was redeemed for one share of Liberty Series A common stock and Liberty
         Series B common stock, respectively. In connection with the Split Off,
         participants' balances in the AT&T Liberty Media Stock Fund were
         transferred to the Liberty Media Stock Fund.

         TRUST FUND MANAGED BY FIDELITY MANAGEMENT TRUST COMPANY ("TRUSTEE")

         Under the terms of a trust agreement between the Trustee and the
         Liberty Plan, the Trustee manages a trust fund on behalf of the Liberty
         Plan and has been granted authority concerning purchases and sales of
         investments for the trust fund. The Trustee may invest up to 100% of
         the assets of the Liberty Plan in employer securities without regard to
         any fiduciary requirement to diversify Liberty Plan assets.
         Additionally, the Liberty Plan is allowed to invest in non-employer
         securities.

         INVESTMENTS

         Investments are reflected in the accompanying financial statements at
         fair value. Fair value represents the closing prices for those
         securities having readily available market quotations and fair value as
         determined by the Trustee with respect to other securities. The stock
         funds are unitized funds that are measured in units rather than shares.
         The unitized stock funds consist mostly of stock with an insignificant
         amount of cash or cash equivalents. The per share fair values used for
         investments in common stock are as follows:



                                                                                        December 31,
                                                                        ----------------------------------------
                                                                                 2001                 2000
                                                                        -------------------    -----------------
                                                                                         
                  Liberty Series A common stock                               $   14.00                 N/A
                  Liberty Livewire Class A common stock                       $    6.94                 N/A
                  AT&T common stock                                                 N/A             $ 17.25
                  AT&T Class A Liberty Media Group common stock                     N/A             $ 13.56


         The foregoing prices are the closing market prices of the common stocks
         on those dates. Changes in market values after the Liberty Plan's year
         end are not reflected in the accompanying financial statements.

                        LIBERTY MEDIA 401(k) SAVINGS PLAN

                          Notes to Financial Statements

         Securities and investment transactions are accounted for on the trade
         date. Distributions are priced at fair value and are accounted for when
         shares are transferred by the Trustee to participants. The cost basis
         of such shares distributed is determined using the "first-in,
         first-out" method. Dividend income is recorded on the ex-dividend date.
         Income from other investments is recorded as earned on an accrual
         basis.

         INCOME TAXES

         The Internal Revenue Service has determined and informed Liberty by a
         letter dated March 1, 2001, that the Liberty Plan and related trust are
         designed in accordance with applicable sections of the Internal Revenue
         Code ("IRC"). Once qualified, the Liberty Plan is required to operate
         in conformity with the IRC to maintain its qualification. The Liberty
         Plan administrator is not aware of any course of action or series of
         events that have occurred that might adversely affect the Liberty
         Plan's qualified status.

         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 disclosure of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of additions
         and deductions during the reporting period. Actual results could differ
         significantly from those estimates.

         PLAN EXPENSES

         Any employer contribution amounts forfeited may be used to pay plan
         expenses except for loan origination fees, which are paid by
         participants. Any additional administrative expenses of the Liberty
         Plan are paid by Liberty.

(2)      DESCRIPTION OF THE LIBERTY PLAN

         The following description of the Liberty Plan is provided for general
         information purposes only. Participants should refer to the plan
         document for more complete information.

         GENERAL

         Effective March 2, 1999 the Liberty Plan was created as a spin-off of
         the TCI 401(k) Stock Plan. The Liberty Plan is a defined contribution
         plan sponsored by Liberty, which enables participating employees of
         Liberty and its qualifying subsidiaries to receive an interest in
         Liberty and to receive benefits upon retirement. Employees of Liberty
         and its 80% owned subsidiaries who are at least 18 years of age and (i)
         have worked at least three consecutive months or (ii) have completed
         one year of service (as defined in the Liberty Plan document) are
         eligible to participate in the Liberty Plan.

                        LIBERTY MEDIA 401(k) SAVINGS PLAN

                          Notes to Financial Statements

         CONTRIBUTIONS

         Participants, other than employees of Liberty Livewire, may contribute
         on a pre-tax or after-tax basis up to 10% of their compensation, as
         defined, to the Liberty Plan. Liberty and its subsidiaries, other than
         Liberty Livewire, make matching contributions equal to 100% of
         participant contributions, up to a maximum match of 10% of eligible
         compensation. Participants who are employees of Liberty Livewire may
         contribute on a pre-tax or after-tax basis up to 15% of their
         compensation, as defined, to the Liberty Plan. Liberty Livewire makes
         matching contributions equal to $.50 for each $1.00 contributed by the
         participant up to 6% of eligible compensation. Employer contributions
         are made to the Liberty Media Stock Fund. Employee contributions may be
         made to any investments in the Liberty Plan, including the Liberty
         Media Stock Fund. Liberty reserves the right to change the matching
         contribution amount at any time.

         PARTICIPANT LOANS

         Participants may borrow from their fund accounts a minimum of $1,000 up
         to the lesser of $50,000 or 50% of their vested account balance. Loans,
         other than those transferred from other plans, must be repaid within
         five years and bear interest at a rate equal to prime rate in effect on
         the first day of the calendar quarter in which the loan is originated
         plus 1%. Loans transferred from other plans, as described in note 4,
         retain the repayment terms and interest rates in effect at the time of
         transfer. Loans are secured by the vested balance in the participant's
         account, and bear interest at rates ranging from 6.5% to 10.5% at
         December 31, 2001. Principal and interest are paid ratably through
         monthly payroll deductions.

         FORFEITURES

         Forfeitures (due to participants' termination prior to full vesting)
         are first used to pay Liberty Plan expenses, with any excess used to
         reduce Liberty's future matching contributions. Forfeitures aggregated
         $233,000 and $285,000 during 2001 and 2000, respectively. Unused
         forfeitures aggregated $245,000 and $140,000 at December 31, 2001 and
         2000, respectively. Participant contributions are always fully vested.

         INVESTMENT OPTIONS

         As of December 31, 2001, the Liberty Plan has six investment options
         including five mutual funds and one unitized stock fund: a money market
         mutual fund, a growth and income mutual fund, a diversified growth
         mutual fund, an income mutual fund, a global growth fund, and the
         Liberty Media Stock Fund. In addition to the foregoing investment
         options, the Liberty Plan had assets of $100,000 invested in Liberty
         Livewire Corporation Stock Fund at December 31, 2001. The Liberty
         Livewire common stock was transferred into the Liberty Plan upon
         completion of the merger of certain Liberty Livewire retirement plans
         in June 2001 (see note 4). Subsequent to December 31, 2001, the Liberty
         Livewire common stock was converted to Liberty Series A common stock.
         Plan participants may change investment options and contribution
         percentages on a daily basis.

         BENEFIT PAYMENTS

         Distributions from the Liberty Plan may be made to a participant upon
         death, total disability, financial hardship or termination of
         employment. Distributions and other withdrawals are processed on a
         daily basis.

         VESTING

         Participants acquire a vested right in employer matching contributions,
         other than employer contributions transferred from other plans, as
         follows:

                           3 years                            100%


         Employer matching contributions transferred from other plans, as
         described in note 4, vest according to the terms specified in the
         Subsidiary Plans.

         PLAN TERMINATION

         Although Liberty has not expressed any intent to terminate the Liberty
         Plan, it may do so at any time, subject to the provisions of ERISA. The
         Liberty Plan provides for full and immediate vesting of all participant
         rights upon termination of the Liberty Plan.

(3)      INVESTMENTS

         The fair value of individual investments that represent 5% or more of
         the Liberty Plan's net assets at December 31, 2001 and 2000 are as

         the Wireless spin-off, holders of AT&T common stock, including shares
         held by the AT&T Stock Fund, received .3218 of a share of Wireless
         stock for each share of AT&T common stock owned. Such Wireless stock

         Effective May 25, 2001, and as a result of a merger transaction between
         a subsidiary of Liberty and an unaffiliated third party, a partial plan
         termination occurred. In connection therewith, employees of such
         subsidiary, who were active participants in the Liberty Plan on May 25,
         2001 (the "Subsidiary Employees"), were terminated from the Liberty
         Plan. The Subsidiary Employees became fully vested in their employer
         contributions upon the partial plan termination.

(1)      An unintentional delay by a subsidiary of Liberty in submitting a
         certain 2001 employee contribution in the amount of $2,844 to the
         trustee resulted in a prohibited transaction. Effectively a loan from
         the Liberty Plan to a subsidiary of Liberty, this amount was remitted
         to the trustee later than allowed by Department of Labor regulations.
         Liberty intends to reimburse the Liberty Plan $5 for lost earnings and
         interest thereon in 2002.
