NOTES TO FINANCIAL STATEMENTS

- --------------------------------------------------------------------------------
 1. Significant Accounting Policies
 Centennial Money Market Trust (the Trust) is registered under the Investment
 Company Act of 1940, as amended, as an open-end management investment company.
 The Trust's investment objective is to seek the maximum current income that is
 consistent with low capital risk and the maintenance of liquidity. The Trust's
 investment advisor is Centennial Asset Management Corporation (the Manager), a
 subsidiary of OppenheimerFunds, Inc. (OFI).
    The following is a summary of significant accounting policies consistently
 followed by the Trust.
- --------------------------------------------------------------------------------
 Securities Valuation. Portfolio securities are valued on the basis of amortized
 cost, which approximates market value.
- --------------------------------------------------------------------------------
 Securities On a When-issued Basis. Delivery and payment for securities that
 have been purchased by the Trust on a when-issued basis can take place a month
 or more after the trade date. Normally the settlement date occurs within six
 months after the trade date; however, the Trust may, from time to time,
 purchase securities whose settlement date extends six months or more beyond
 trade date. During this period, such securities do not earn interest, are
 subject to market fluctuation and may increase or decrease in value prior to
 their delivery. The Trust maintains segregated assets with a market value equal
 to or greater than the amount of its purchase commitments. The purchase of
 securities on a when-issued basis may increase the volatility of the Trust's
 net asset value to the extent the Trust makes such purchases while remaining
 substantially fully invested. As of June 30, 2003, the Trust had entered into
 when-issued purchase commitments of $160,600,601.
- --------------------------------------------------------------------------------
 Federal Taxes. The Trust intends to continue to comply with provisions of the
 Internal Revenue Code applicable to regulated investment companies and to
 distribute all of its taxable income to shareholders. Therefore, no federal
 income or excise tax provision is required.

 The tax components of capital shown in the table below represent distribution
 requirements the Trust must satisfy under the income tax regulations, losses
 the Trust may be able to offset against income and gains realized in future
 years for federal income tax purposes.

 1. Significant Accounting Policies Continued
 Net investment income (loss) and net realized gain (loss) may differ for
 financial statement and tax purposes. The character of dividends and
 distributions made during the fiscal year from net investment income or net
 realized gains may differ from their ultimate characterization for federal
 income tax purposes. Also, due to timing of dividends and distributions, the
 fiscal year in which amounts are distributed may differ from the fiscal year in
 which the income or net realized gain was recorded by the Trust.

 connection with Trust share redemptions.

 The tax character of distributions paid during the years ended June 30, 2003
 and June 30, 2002 were as follows:

                                             ==============================

- --------------------------------------------------------------------------------
 Dividends and Distributions to Shareholders. Dividends and distributions to
 shareholders, which are determined in accordance with income tax regulations,
 are recorded on the ex-dividend date. Income distributions, if any, are
 declared daily and paid monthly. Capital gain distributions, if any, are
 declared and paid annually.
- --------------------------------------------------------------------------------
 Expense Offset Arrangement. The reduction of custodian fees represents earnings
 on cash balances maintained by the Trust.
- --------------------------------------------------------------------------------
 Security Transactions. Security transactions are recorded on the trade date.
 Realized gains and losses on securities sold are determined on the basis of
 identified cost.
- --------------------------------------------------------------------------------
 Other. The preparation of financial statements in conformity with accounting
 principles generally accepted in the United States of America 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 income and
 expenses during the reporting period. Actual results could differ from those
 estimates.

 3. Fees and Other Transactions With Affiliates
 Management Fees. Management fees paid to the Manager were in accordance with
 the investment advisory agreement with the Trust which provides for a fee at an
 annual rate of 0.50% of the first $250 million of the Trust's net assets,
 0.475% of the next $250 million, 0.45% of the next $250 million, 0.425% of the
 next $250 million, 0.40% of the next $250 million, 0.375% of the next $250
 million, 0.35% of the next $500 million, and 0.325% of net assets in excess of
 $2 billion. In the agreement, the Manager guarantees that the Trust's total
 expenses in any fiscal year, exclusive of taxes, interest and brokerage
 concessions, and extraordinary expenses such as litigation costs, shall not
 exceed the lesser of 1.5% of the average annual net assets of the Trust up to
 $30 million and 1% of its average annual net assets in excess of $30 million;
 or 25% of the total annual investment income of the Trust. As a result of this
 agreement, the Trust was reimbursed $60,805,404, for the year ended June 30,
 2003.
    On April 28, 2003, the Board of Trustees approved a new investment advisory
 agreement that would eliminate the expense limitation and resulting
 reimbursement from the Manager. This new investment advisory agreement has been
 submitted to shareholders for approval and will be effective only if affirmed
 by shareholder vote.
- --------------------------------------------------------------------------------
 Transfer Agent Fees. Shareholder Services, Inc. (SSI) acts as the transfer and
 shareholder servicing agent for the Trust and for other registered investment
 companies. The Trust pays SSI a $14.75 per account fee.
    SSI has voluntarily agreed to limit transfer and shareholder servicing agent
 fees up to an annual rate of 0.35% of average net assets of the Trust. This
 undertaking may be amended or withdrawn at any time.
- --------------------------------------------------------------------------------
 Service Plan (12B-1) Fees. The Trust has adopted a service plan. It reimburses
 the Distributor for a portion of its costs incurred for services provided to
 accounts that hold shares of the Trust. Reimbursement is made quarterly at an
 annual rate up to 0.20% of the average annual net assets of the Trust. During
 the year ended June 30, 2003, the Trust paid $1,022 to a broker/dealer
 affiliated with the Manager as reimbursement for distribution-related expenses.

 4. Illiquid Securities
 As of June 30, 2003, investments in securities included issues that are
 illiquid. A security may be considered illiquid if it lacks a readily available
 market or if its valuation has not changed for a certain period of time. The
 Trust intends to invest no more than 10% of its net assets (determined at the
 time of purchase and reviewed periodically) in illiquid securities. The
 aggregate value of illiquid securities subject to this limitation as of June
 30, 2003 was $885,256,067, which represents 3.85% of the Trust's net assets.

INDEPENDENT AUDITORS' REPORT

- --------------------------------------------------------------------------------
 To the Board of Trustees and Shareholders of Centennial Money Market Trust:
 We have audited the accompanying statement of assets and liabilities of
 Centennial Money Market Trust, including the statement of investments, as of
 June 30, 2003, and the related statement of operations for the year then ended,
 the statements of changes in net assets for each of the two years in the period
 then ended, and the financial highlights for each of the five years in the
 period then ended. These financial statements and financial highlights are the
 responsibility of the Trust's management. Our responsibility is to express an
 opinion on these financial statements and financial highlights 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 and financial highlights are free of material
 misstatement. An audit includes examining, on a test basis, evidence supporting
 the amounts and disclosures in the financial statements. Our procedures
 included confirmation of securities owned as of June 30, 2003, by
 correspondence with the custodian and brokers; where replies were not received
 from brokers, we performed other auditing procedures. 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 and financial highlights referred
 to above present fairly, in all material respects, the financial position of
 Centennial Money Market Trust as of June 30, 2003, the results of its
 operations for the year then ended, the changes in its net assets for each of
 the two years in the period then ended, and the financial highlights for each
 of the five years in the period then ended, in conformity with accounting
 principles generally accepted in the United States of America.
