SIGNIFICANT ACCOUNTING POLICIES Oppenheimer Principal Protected Main Street Fund (the Fund), a series of Oppenheimer Principal Protected Trust, is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. The Fund seeks capital preservation in order to have a net asset value on the Maturity Date at least equal to your original investment (the Warranty Amount) (net of any sales charges and less your share of extraordinary expenses and the proportional reduction of dividends paid in cash and redemption of the Fund shares). The Fund's investment advisor is OppenheimerFunds, Inc. (the Manager). Shares of the Fund were offered during the Offering Period (May 30, 2003 to July 31, 2003). Shares are not offered during the Warranty Period (August 5, 2003 to August 5, 2010) to the Maturity Date (August 5, 2010) except in connection with reinvestment of dividends and distributions. During the Warranty Period, the Fund will seek capital preservation, and secondarily high total return by allocating its assets between Oppenheimer Main Street Fund and certain U.S. government securities. The Fund offered Class A, Class B, Class C and Class N shares. Class A shares were sold at their offering price, which is normally net asset value plus a front-end sales charge. Class B, Class C and Class N shares were sold without a front-end sales charge but may be subject to a contingent deferred sales charge (CDSC). Class N shares were sold only through retirement plans. Retirement plans that offer Class N shares may impose charges on those accounts. All classes of shares have identical rights and voting privileges with respect to the Fund in general and exclusive voting rights on matters that affect that class alone. Earnings, net assets and net asset value per share may differ by minor amounts due to each class having its own expenses directly attributable to that class. Classes A, B, C and N have separate distribution and/or service plans. Class B shares will automatically convert to Class A shares 88 months after the date of purchase. The following is a summary of significant accounting policies consistently followed by the Fund. ------------------------------------------------------------------------------- WARRANTY AGREEMENT. The Fund has entered into a Financial Warranty Agreement with Merrill Lynch Bank USA (the Warranty Provider) to ensure that on the Maturity Date each shareholder's account will be no less than the value of that shareholder's account on the second business day after the end of the Offering Period. This value will include net income, if any, earned by the Fund during the offering period and reduced by adjustments permitted under the Warranty Agreement, sales charges, applicable share of extraordinary expenses and proportionately reduced for dividends and distributions paid in cash and redemptions of Fund shares. To avoid a reduced warranty amount, shareholders must reinvest all dividends and distributions received from the Fund to purchase additional shares of the Fund and must not redeem any shares of the Fund during the Warranty Period. If the value of the Fund's assets on the Maturity Date is insufficient to result in the value of each shareholder's account being at least equal to the shareholder's Warranty Amount, the Warranty Provider will pay the Fund an amount equal to his or her Warranty Amount. 15 | Oppenheimer Principal Protected Main Street Fund NOTES TO FINANCIAL STATEMENTS UNAUDITED / CONTINUED - -------------------------------------------------------------------------------- ------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued The Financial Warranty is solely the obligation of the Warranty Provider. It is possible that the financial position of the Warranty Provider may deteriorate and it would be unable to satisfy its obligations under the Financial Warranty. The Fund's assets and the obligations of the Warranty Provider under the Warranty Agreement are not guaranteed by Merrill Lynch & Co., Inc. (the Warranty Provider's parent company), the United States Government, the Manager, or any other entity or person. The Warranty Agreement requires the Manager, on behalf of the Fund, to comply with certain agreed upon investment parameters in an attempt to limit the Fund's risk. If the Manager fails to comply with the agreed-upon investment parameters or otherwise fails to comply with certain requirements set forth in the Warranty Agreement, the Warranty Provider may terminate its Financial Warranty in certain limited circumstances. The Warranty Provider may monitor the Fund's compliance with the Warranty Agreement solely to protect the interests of the Warranty Provider and not the Fund's shareholders. The fee paid to the Warranty Provider is an annual fee of 0.60% of the average daily net assets of the Fund. If the Fund is required to make a complete and irreversible allocation of its assets to the debt portfolio, the Warranty Fee will thereafter be reduced to 0.35% of the average daily net assets of the Fund. For the six months ended February 29, 2004, the amount paid for Warranty Agreement fees was $667,475. ------------------------------------------------------------------------------- SECURITIES VALUATION. The allocation of the Fund's assets between the debt portfolio and the equity portfolio will vary over time based upon the Warranty Formula. The formula is intended to allow the Fund to have a net asset value on the Maturity Date at least equal to the Warranty Amount. During the Warranty Period, the Fund will invest a portion of its assets, and in certain circumstances, the Fund may invest all of its assets, in U.S. government securities having maturity approximately equal to the period remaining in the Warranty Period. Long-term and short-term "non-money market" debt securities are valued by a portfolio pricing service approved by the Board of Trustees. Short-term "money market type" debt securities with remaining maturities of sixty days or less are valued at amortized cost (which approximates market value). The Fund invests the equity portfolio in Class Y shares of Oppenheimer Main Street Fund (the Underlying Fund). The net asset value of the Underlying Fund is determined as of the close of The New York Exchange, on each day the Exchange is open for trading. The net asset value per share is determined by dividing the value of the Fund's net assets attributable to a class by the number of shares of that class that are outstanding. ------------------------------------------------------------------------------- JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated funds advised by the Manager, may transfer uninvested cash balances into joint trading accounts on a daily basis. Secured by U.S. government securities, these balances are invested in one or more repurchase agreements. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the 16 | Oppenheimer Principal Protected Main Street Fund market value of the collateral be sufficient to cover payments of interest and principal. In the event of default by the other party to the agreement, retention of the collateral may be subject to legal proceedings. ------------------------------------------------------------------------------- ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. ------------------------------------------------------------------------------- FEDERAL TAXES. The Fund 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, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders, therefore, no federal income or excise tax provision is required. As of February 29, 2004, the Fund had no estimated unused capital loss carryforward available for federal income tax purposes. ------------------------------------------------------------------------------- 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 Fund. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of the Fund or are invested in other Oppenheimer funds selected by the Trustee. Deferral of trustees' fees under the plan will not affect the net assets of the Fund, and will not materially affect the Fund'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 and capital gain distributions, if any, are declared and paid annually. ------------------------------------------------------------------------------- INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income, which includes accretion of discount and amortization of premium, is accrued as earned. ------------------------------------------------------------------------------- EXPENSE OFFSET ARRANGEMENT. The reduction of custodian fees, if applicable, represents earnings on cash balances maintained by the Fund. ------------------------------------------------------------------------------- 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 17 | Oppenheimer Principal Protected Main Street Fund NOTES TO FINANCIAL STATEMENTS UNAUDITED / CONTINUED - -------------------------------------------------------------------------------- ------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued 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 Fund has authorized an unlimited number of $0.001 par value shares of beneficial interest of each class. Transactions in shares of beneficial interest were as follows: SIX MONTHS ENDED FEBRUARY 29, 2004 PERIOD ENDED AUGUST 31, 2003 1 SHARES AMOUNT SHARES AMOUNT - ----------------------------------------------------------------------------------------------------- CLASS A Sold -- $ -- 7,734,040 $ 77,290,054 2 Dividends and/or distributions reinvested 66,031 726,342 -- -- Redeemed (580,660) (6,471,909) (75,844) (762,910) ------------------------------------------------------------------ Net increase (decrease) (514,629) $(5,745,567) 7,658,196 $ 76,527,144 ================================================================== - ----------------------------------------------------------------------------------------------------- CLASS B Sold -- $ -- 12,010,627 $120,027,161 2 Dividends and/or distributions reinvested 65,444 719,894 -- -- Redeemed (295,651) (3,184,143) (45,240) (454,845) ------------------------------------------------------------------ Net increase (decrease) (230,207) $(2,464,249) 11,965,387 $119,572,316 ================================================================== - ----------------------------------------------------------------------------------------------------- CLASS C Sold -- $ -- 5,882,060 $ 58,782,614 2 Dividends and/or distributions reinvested 25,625 281,883 -- -- Redeemed (493,772) (5,452,412) (17,401) (174,989) ------------------------------------------------------------------ Net increase (decrease) (468,147) $(5,170,529) 5,864,659 $ 58,607,625 ================================================================== - ----------------------------------------------------------------------------------------------------- CLASS N Sold -- $ -- 528,325$ $ 5,279,783 2 Dividends and/or distributions reinvested 4,395 48,349 -- -- Redeemed (61,163) (681,929) -- -- ------------------------------------------------------------------ Net increase (decrease) (56,768) $ (633,580) 528,325 $ 5,279,783 ================================================================== <FN> 1. For the period from June 2, 2003 (commencement of operations) to August 31, 2003. 2. Costs incurred by the Fund for obtaining the Warranty Agreement for the benefit of share purchases during the Offering Period were $171,068, and are included in Paid-in-Capital. </FN> ------------------------------------------------------------------------------- 3. PURCHASES AND SALES OF SECURITIES The aggregate cost of purchases and proceeds from sales of securities, other than short-term obligations, for the six months ended February 29, 2004, were $557,304,599 and $315,902,593, respectively. 18 | Oppenheimer Principal Protected Main Street Fund ------------------------------------------------------------------------------- 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the investment advisory agreement with the Fund which provides for a fee at an annual rate of 0.50% of the average annual net assets of the Fund, reduced by the amount of advisory fees paid to the Manager by the Underlying Fund relating to the Fund's assets invested in the Underlying Fund, but not below zero. That fee will apply during the Warranty Period and the Post-Warranty Period. If during the Warranty Period 100% of the Fund's assets are completely and irreversibly invested in the debt portfolio, the management fee will be at an annual rate of 0.25% of the average annual net assets of the Fund, and if that occurs the Manager will further reduce its management fee to the extent necessary so that total annual operating expenses of the Fund (other than Extraordinary Expenses such as litigation costs) do not exceed 1.30% for Class A shares, 2.05% for Class B shares, 2.05% for Class C shares and 1.55% for Class N shares. However, if this reduction in the management fee is not sufficient to reduce total annual operating expenses to these limits, the Manager is not required to subsidize Fund expenses to assure that expenses do not exceed those limits. Furthermore, if expenses exceed these expense limits, the Warranty Amount will be reduced by any expenses that exceed those limits. In addition, during the Warranty Period the Manager has voluntarily agreed to reduce the management fee payable by the Fund by 0.00833% per month in any month following a month where the Fund's average daily equity allocation was less than 10%. Those voluntary undertakings may be amended or eliminated at any time. The Manager has voluntarily undertaken to reimburse the Fund for expenses equal to the Underlying Fund expenses, other than Underlying Fund management fees, paid by the Fund as a shareholder of the Underlying Fund. That expense reimbursement will fluctuate as the Fund's allocation between the Underlying Fund and the debt portfolio changes. This voluntary undertaking may be amended or eliminated at any time. ------------------------------------------------------------------------------- TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the Manager, acts as the transfer and shareholder servicing agent for the Fund. The Fund pays OFS a per account fee.

BORROWING AND LENDING ARRANGEMENTS The Fund entered into an "interfund borrowing and lending arrangement" with other funds in the Oppenheimer funds complex, to allow funds to borrow for liquidity purposes. The arrangement was initiated pursuant to exemptive relief granted by the Securities and Exchange Commission (the SEC) to allow these affiliated funds to lend money to, and borrow money from, each other, in an attempt to reduce borrowing costs below those of bank loan facilities. The SEC's order requires the Fund's Board of Trustees to adopt operating policies and procedures to administer interfund borrowing and lending. Under the arrangement the Fund may lend money to other Oppenheimer funds and may borrow from other Oppenheimer funds at a rate set by the Fund's Board of Trustees, based upon a recommendation by the Manager. The Fund's borrowings, if any, are subject to asset coverage requirements under the Investment Company Act and the provisions of the SEC order and other applicable regulations. If the Fund borrows money, there is a risk that the loan could be called on one day's notice, in which case the Fund might have to borrow from a bank at higher rates if a loan were not available from another Oppenheimer fund. If the Fund lends money to another fund, it will be subject to the risk that the other fund might not repay the loan in a timely manner, or at all. The Fund had no interfund borrowings or loans outstanding during the six months ended or at February 29, 2004. - -------------------------------------------------------------------------------- PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES UNAUDITED ------------------------------------------------------------------------------- The Fund has adopted Portfolio Proxy Voting Policies and Procedures under which the Fund votes proxies relating to securities ("portfolio proxies") held by the Fund.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS The Board is responsible for approving nominees for election as trustees. To assist in this task, the Board has designated the Audit Committee as the nominating committee for the Board. It reviews and recommends nominees to the Board. The Committee is comprised entirely of disinterested trustees as defined in Section 2(a)(19) of the Investment Company Act of 1940. The Audit Committee charter describes the responsibilities of the Committee in nominating candidates for election as independent Trustees of the Registrant. The Registrant's Board has adopted a written charter for the Committee. A current copy of the Audit Committee charter is available to shareholders on the OppenheimerFunds website at www.oppenheimerfunds.com. Under the current policy, if the Board determines that a vacancy exists or is likely to exist on the Board, the Audit Committee of the Board will consider candidates for Board membership including recommended by Registrant shareholders. The Audit Committee will consider nominees recommended by independent Board members or recommended by any other Board members including Board members affiliated with the Registrant's investment advisors. The Committee may, upon Board approval, retain an executive search firm to assist in screening potential candidates. Upon Board approval, the Audit Committee may also use the services of legal, financial, or other external counsel that it deems necessary or desirable in the screening process. Shareholders wishing to submit a nominee for election to the Board may do so by mailing their submission to the offices of OppenheimerFunds, Inc., 6803 South Tucson Way, Centennial, CO 80112, to the attention of the Board of Trustees of the named Registrant, c/o the Secretary of the Registrant. The Committee's process for identifying and evaluating nominees for trustee includes a number of factors. In screening candidates for board membership, whether the candidate is suggested by Board members, shareholders or others, the Committee considers the candidate's professional experience, soundness of judgment, integrity, ability to make independent, analytical inquiries, collegiality, willingness and ability to devote the time required to perform Board activities adequately, ability to represent the interests of all shareholders of the Registrant, and diversity relative to the board's composition. Candidates are expected to provide a mix of attributes, experience, perspective and skills necessary to effectively advance the interests of shareholders. ITEM 10.
