ZACK, ESQ. OPPENHEIMERFUNDS, INC. TWO WORLD FINANCIAL CENTER, NEW YORK, NEW YORK 10281-1008 (Name and address of agent for service) Registrant's telephone number, including area code: (303) 768-3200 Date of fiscal year end: JUNE Date of reporting period: 06/30/2006 ITEM 1. REPORTS TO STOCKHOLDERS. FUND EXPENSES - -------------------------------------------------------------------------------- FUND EXPENSES. As a shareholder of the Trust, you incur ongoing costs, including management fees; service fees and other Trust expenses. These examples are intended to help you understand your ongoing costs (in dollars) of investing in the Trust and to compare these costs with the ongoing costs of investing in other mutual funds. The examples are based on an investment of $1,000.00 invested at the beginning of the period and held for the entire 6-month period ended June 30, 2006. ACTUAL EXPENSES. The "actual" lines of the table provide information about actual account values and actual expenses. You may use the information on this line, together with the amount you invested, to estimate the expense that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00 = 8.60), then multiply the result by the number in the "actual" line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the table provide information about hypothetical account values and hypothetical expenses based on the Trust's actual expense ratio, and an assumed rate of return of 5% per year before expenses, which is not the Trust's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Trust and other funds. To do so, compare this 5% hypothetical example for the class of shares you hold with the 5% hypothetical examples that appear in the shareholder reports of the other funds. 5 | CENTENNIAL MONEY MARKET TRUST FUND EXPENSES - -------------------------------------------------------------------------------- BEGINNING ENDING EXPENSES ACCOUNT ACCOUNT PAID DURING VALUE VALUE 6 MONTHS ENDED (1/1/06) (6/30/06) JUNE 30, 2006 - -------------------------------------------------------------------------------- Actual $1,000.00 $1,020.60 $ 3.36 - -------------------------------------------------------------------------------- Hypothetical 1,000.00 1,021.47 3.36 Hypothetical assumes 5% annual return before expenses.

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS. 17 | CENTENNIAL MONEY MARKET TRUST 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 wholly owned subsidiary of OppenheimerFunds, Inc. (OFI). The following is a summary of significant accounting policies consistently followed by the Trust. - -------------------------------------------------------------------------------- SECURITIES VALUATION. The net asset value of shares of the Trust is normally determined twice each day, at 12:00 Noon Eastern time and at 4:00 P.M. Eastern time on each day the New York Stock Exchange (the "Exchange") is open for trading. Portfolio securities are valued on the basis of amortized cost, which approximates market value. - -------------------------------------------------------------------------------- FEDERAL TAXES. The Trust intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company 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. UNDISTRIBUTED NET UNDISTRIBUTED ACCUMULATED LOSS INVESTMENT INCOME LONG-TERM GAIN CARRYFORWARD 1,2 -------------------------------------------------------- $34,127,752 $-- $-- 1. During the fiscal year ended June 30, 2006, the Trust did not utilize any capital loss carryforward. 2. During the fiscal year ended June 30, 2005, the Trust did not utilize any capital loss carryforward. 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. REDUCTION TO INCREASE REDUCTION TO ACCUMULATED NET TO PAID-IN ACCUMULATED NET REALIZED GAIN CAPITAL INVESTMENT LOSS ON INVESTMENTS -------------------------------------------------------- $3 $14,140 $14,143 The tax character of distributions paid during the years ended June 30, 2006 and June 30, 2005 was as follows: YEAR ENDED YEAR ENDED JUNE 30, 2006 JUNE 30, 2005 -------------------------------------------------------- Distributions paid from: Ordinary income $780,304,698 $329,636,607 18 | CENTENNIAL MONEY MARKET TRUST - -------------------------------------------------------------------------------- TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Trust. For purposes of determining the amount owed to the Trustee under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of the Trust or in other Oppenheimer funds selected by the Trustee. The Trust purchases shares of the funds selected for deferral by the Trustee in amounts equal to his or her deemed investment, resulting in a Trust asset equal to the deferred compensation liability. Such assets are included as a component of "Other" within the asset section of the Statement of Assets and Liabilities. Deferral of trustees' fees under the plan will not affect the net assets of the Trust, and will not materially affect the Trust's assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance to the Plan. - -------------------------------------------------------------------------------- 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 but may be paid at other times to maintain the net asset value per share at $1.00. - -------------------------------------------------------------------------------- CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may include interest expense incurred by the Trust on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Trust pays interest to its custodian on such cash overdrafts, to the extent they are not offset by positive cash balances maintained by the Trust, at a rate equal to the Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item, if applicable, represents earnings on cash balances maintained by the Trust during the period. Such interest expense and other custodian fees may be paid with these earnings. At June 30, 2006, the Trust had $624 of such earnings on cash balances available to offset future custodian fees or interest expenses incurred during the next fiscal year. - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- INDEMNIFICATIONS. The Trust's organizational documents provide current and former trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Trust. In the normal course of business, the Trust may also enter into contracts that provide general indemnifications. The Trust's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Trust. The risk of material loss from such claims is considered remote. 19 | CENTENNIAL MONEY MARKET TRUST NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued OTHER. The preparation of financial statements in conformity with U.S. 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 income and expenses during the reporting period. Actual results could differ from those estimates. - -------------------------------------------------------------------------------- 2. SHARES OF BENEFICIAL INTEREST The Trust has authorized an unlimited number of no par value shares of beneficial interest. Transactions in shares of beneficial interest were as follows: YEAR ENDED JUNE 30, 2006 YEAR ENDED JUNE 30, 2005 SHARES AMOUNT SHARES AMOUNT - -------------------------------------------------------------------------------------------------------- Sold 66,530,186,460 $ 66,530,186,460 56,763,898,768 $ 56,763,898,768 Dividends and/or distributions reinvested 175,850,368 175,802,322 313,495,015 313,495,015 Redeemed (64,588,767,429) (64,588,767,429) (57,961,547,512) (57,961,547,512) ---------------------------------------------------------------------------- Net increase (decrease) 2,117,269,399 $ 2,117,221,353 (884,153,729) $ (884,153,729) ============================================================================ - -------------------------------------------------------------------------------- 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 average annual rate as shown in the following table: FEE SCHEDULE ---------------------------------------------- Up to $250 million of net assets 0.500% Next $250 million of net assets 0.475 Next $250 million of net assets 0.450 Next $250 million of net assets 0.425 Next $250 million of net assets 0.400 Next $250 million of net assets 0.375 Next $500 million of net assets 0.350 Over $2 billion of net assets 0.325 - -------------------------------------------------------------------------------- ADMINISTRATION SERVICE FEES. The Trust pays the Manager a fee of $1,500 per year for preparing and filing the Trust's tax returns. - -------------------------------------------------------------------------------- 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 per account fee. For the year ended June 30, 2006, the Trust paid $26,580,525 to SSI for services to the Trust. - -------------------------------------------------------------------------------- SERVICE PLAN (12b-1) FEES. The Trust has adopted a service plan. It reimburses Centennial Asset Management Corporation, the Distributor, for a portion of its costs incurred for services provided to accounts that hold shares of the Trust. Reimbursement is made periodically, depending on asset size, at an annual rate of up to 0.20% of the average annual net assets of the Trust. The Distributor currently uses all of those fees to pay dealers, brokers, banks and 20 | CENTENNIAL MONEY MARKET TRUST other financial institutions periodically for providing personal services and maintenance of accounts of their customers that hold shares of the Trust. Fees incurred by the Trust under the Plan are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- WAIVERS AND REIMBURSEMENTS OF EXPENSES. OFS has voluntarily agreed to limit transfer and shareholder servicing agent fees to 0.35% of average annual net assets of the Trust. This undertaking may be amended or withdrawn at any time. - -------------------------------------------------------------------------------- 4. ILLIQUID SECURITIES As of June 30, 2006, 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 will not invest more than 10% of its net assets (determined at the time of purchase and reviewed periodically) in illiquid securities. Securities that are illiquid are marked with the applicable footnote on the Statement of Investments. 21 | CENTENNIAL MONEY MARKET TRUST REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 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, 2006, 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 periods presented. 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 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 and financial highlights are free of material misstatement. The Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also 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, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of June 30, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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, 2006, 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 periods presented, in conformity with accounting principles generally accepted in the United States of America.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS 1. The Fund's Governance Committee (the "Committee") will evaluate potential Board candidates to assess their qualifications. The Committee shall have the authority, upon approval of the Board, to retain an executive search firm to assist in this effort. The Committee may consider recommendations by business and personal contacts of current Board members and by executive search firms which the Committee may engage from time to time and may also consider shareholder recommendations. The Committee may consider the advice and recommendation of the Funds' investment manager and its affiliates in making the selection. 2. The Committee shall screen candidates for Board membership. The Committee has not established specific qualifications that it believes must be met by a trustee nominee. In evaluating trustee nominees, the Committee considers, among other things, an individual's background, skills, and experience; whether the individual is an "interested person" as defined in the Investment Company Act of 1940; and whether the individual would be deemed an "audit committee financial expert" within the meaning of applicable SEC rules. The Committee also considers whether the individual's background, skills, and experience will complement the background, skills, and experience of other nominees and will contribute to the Board. There are no differences in the manner in which the Committee evaluates nominees for trustees based on whether the nominee is recommended by a shareholder. 3. The Committee may consider nominations from shareholders for the Board at such times as the Committee meets to consider new nominees for the Board. The Committee shall have the sole discretion to determine the candidates to present to the Board and, in such cases where required, to shareholders. Recommendations for trustee nominees should, at a minimum, be accompanied by the following: o the name, address, and business, educational, and/or other pertinent background of the person being recommended; o a statement concerning whether the person is an "interested person" as defined in the Investment Company Act of 1940; o any other information that the Funds would be required to include in a proxy statement concerning the person if he or she was nominated; and o the name and address of the person submitting the recommendation and, if that person is a shareholder, the period for which that person held Fund shares. The recommendation also can include any additional information which the person submitting it believes would assist the Committee in evaluating the recommendation. 4. Shareholders should note that a person who owns securities issued by Massachusetts Mutual Life Insurance Company (the parent company of the Funds' investment adviser) would be deemed an "interested person" under the Investment Company Act of 1940. In addition, certain other relationships with Massachusetts Mutual Life Insurance Company or its subsidiaries, with registered broker-dealers, or with the Funds' outside legal counsel may cause a person to be deemed an "interested person." 5. Before the Committee decides to nominate an individual as a trustee, Committee members and other directors customarily interview the individual in person. In addition, the individual customarily is asked to complete a detailed questionnaire which is designed to elicit information which must be disclosed under SEC and stock exchange rules and to determine whether the individual is subject to any statutory disqualification from serving as a trustee of a registered investment company. ITEM 11. CONTROLS AND PROCEDURES. Based on their evaluation of the registrant's disclosure controls and procedures (as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR 270.30a-3(c)) as of 06/30/2006, the registrant's principal executive officer and principal financial officer found the registrant's disclosure controls and procedures to provide reasonable assurances that information required to be disclosed by the registrant in the reports that it files under the Securities Exchange Act of 1934 (a) is accumulated and communicated to registrant's management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure, and (b) is recorded, processed, summarized and reported, within the time periods specified in the rules and forms adopted by the U.S. Securities and Exchange Commission. There have been no changes in the registrant's internal controls over financial reporting that occurred during the registrant's second fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting.
