SIGNIFICANT ACCOUNTING POLICIES Oppenheimer MidCap Fund (the Fund) is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. The Fund's investment objective is to seek capital appreciation. The Fund's investment advisor is OppenheimerFunds, Inc. (the Manager). The Fund offers Class A, Class B, Class C, Class N and Class Y shares. Class A shares are 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 are sold without a front-end sales charge but may be subject to a contingent deferred sales charge (CDSC). Class N shares are sold only through retirement plans. Retirement plans that offer Class N shares may impose charges on those accounts. Class Y shares are sold to certain institutional investors without either a front-end sales charge or a CDSC. 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. No such plan has been adopted for Class Y shares. Class B shares will automatically convert to Class A shares six years after the date of purchase. The following is a summary of significant accounting policies consistently followed by the Fund. - -------------------------------------------------------------------------------- SECURITIES VALUATION. The Fund calculates the net asset value of its shares as of the close of The New York Stock Exchange (the Exchange), normally 4:00 P.M. Eastern time, on each day the Exchange is open for business. Securities listed or traded on National Stock Exchanges or other domestic or foreign exchanges are valued based on the last sale price of the security traded on that exchange prior to the time when the Fund's assets are valued. Securities traded on NASDAQ are valued based on the closing price provided by NASDAQ prior to the time when the Fund's assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the closing bid and asked prices, and if not, at the closing bid price. Securities may be valued primarily using dealer-supplied valuations or a portfolio pricing service authorized by the Board of Trustees. Securities (including restricted securities) for which market quotations are not readily available are valued at their fair value. Foreign securities whose values have been materially affected by what the Manager identifies as a significant event occurring before the Fund's assets are valued but after the close of their respective foreign exchanges will be fair valued. Fair value is determined in good faith using consistently applied procedures under the supervision of 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). - -------------------------------------------------------------------------------- FOREIGN CURRENCY TRANSLATION. The Fund's accounting records are maintained in U.S. dollars. Prices of securities denominated in foreign currencies are translated into U.S. dollars at the closing rates of exchange. Amounts related to the purchase and sale of foreign 23 | OPPENHEIMER MIDCAP FUND - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued securities and investment income are translated at the rates of exchange prevailing on the respective dates of such transactions. Reported net realized foreign exchange gains or losses arise from sales of portfolio securities, sales and maturities of short-term securities, sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the values of assets and liabilities, including investments in securities at fiscal period end, resulting from changes in exchange rates. The effect of changes in foreign currency exchange rates on investments is separately identified from the fluctuations arising from changes in market values of securities held and reported with all other foreign currency gains and losses in the Fund's Statement of Operations. - -------------------------------------------------------------------------------- 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. 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 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. 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 Fund. As of April 30, 2004, the Fund had available for federal income tax purposes an estimated unused capital loss carryforward of $1,111,882,745 expiring by 2012. This estimated capital 24 | OPPENHEIMER MIDCAP FUND loss carryforward represents carryforward as of the end of the last fiscal year, increased for losses deferred under tax accounting rules to the current fiscal year and is increased or decreased by capital losses or gains realized in the first six months of the current fiscal year. During the six months ended April 30, 2004 and the year ended October 31, 2003, the Fund used $107,007,840 and $0, respectively, of carryforward to offset capital gains realized. As of October 31, 2003, the Fund had available for federal income tax purposes unused capital loss carryforwards as follows: EXPIRING ------------------------------------ 2006 $ 2,792,572 2007 3,516,822 2008 142,020,390 2009 765,032,406 2010 237,892,098 2011 67,636,297 --------------- Total $ 1,218,890,585* =============== *Includes $41,420 from capital loss carryforward acquired in the September 4, 2003 merger with Oppenheimer Select Managers Gartmore Millennium Growth Fund II. - -------------------------------------------------------------------------------- TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for the Fund's independent trustees. Benefits are based on years of service and fees paid to each trustee during the years of service. During the six months ended April 30, 2004, the Fund's projected benefit obligations were increased by $7,668 and payments of $3,871 were made to retired trustees, resulting in an accumulated liability of $150,293 as of April 30, 2004. 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. 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 Fund or in other Oppenheimer funds selected by the Trustee. The Fund does purchase shares of the funds selected for deferral by the Trustee in amounts equal to his or her deemed investment, resulting in a Fund 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 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. 25 | OPPENHEIMER MIDCAP FUND - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon ex-dividend notification in the case of certain foreign dividends where the ex-dividend date may have passed. 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 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. In the ordinary course of business, the Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. - -------------------------------------------------------------------------------- 2. SHARES OF BENEFICIAL INTEREST The Fund has authorized an unlimited number of no par value shares of beneficial interest of each class. Transactions in shares of beneficial interest were as follows: SIX MONTHS ENDED APRIL 30, 2004 YEAR ENDED OCTOBER 31, 2003 SHARES AMOUNT SHARES AMOUNT - ------------------------------------------------------------------------------------------------------------ CLASS A Sold 4,560,324 $ 64,780,613 8,268,487 $ 100,143,126 Acquisition-Note 6 -- -- 317,478 4,460,569 Redeemed (4,713,272) (66,640,299) (8,568,434) (101,677,126) ----------------------------------------------------------------------------- Net increase (decrease) (152,948) $ (1,859,686) 17,531 $ 2,926,569 ============================================================================= - ------------------------------------------------------------------------------------------------------------ CLASS B Sold 2,028,399 $ 27,478,194 4,126,736 $ 48,252,675 Acquisition-Note 6 -- -- 38,399 517,234 Redeemed (3,225,300) (43,698,703) (6,086,687) (69,345,725) ----------------------------------------------------------------------------- Net decrease (1,196,901) $ (16,220,509) (1,921,552) $ (20,575,816) ============================================================================= - ------------------------------------------------------------------------------------------------------------ CLASS C Sold 1,092,726 $ 14,750,075 2,083,749 $ 24,228,356 Acquisition-Note 6 -- -- 33,708 453,714 Redeemed (1,088,278) (14,664,223) (1,956,908) (22,260,768) ----------------------------------------------------------------------------- Net increase 4,448 $ 85,852 160,549 $ 2,421,302 ============================================================================= 26 | OPPENHEIMER MIDCAP FUND SIX MONTHS ENDED APRIL 30, 2004 YEAR ENDED OCTOBER 31, 2003 SHARES AMOUNT SHARES AMOUNT - ------------------------------------------------------------------------------------------------------------ CLASS N Sold 437,218 $ 6,154,939 680,615 $ 8,317,381 Acquisition-Note 6 -- -- 11,483 160,308 Redeemed (302,455) (4,212,797) (271,906) (3,340,257) --------------------------------------------------------------------------- Net increase 134,763 $ 1,942,142 420,192 $ 5,137,432 =========================================================================== - ------------------------------------------------------------------------------------------------------------ CLASS Y Sold 386,676 $ 5,683,293 896,395 $ 11,097,195 Acquisition-Note 6 -- -- 52 743 Redeemed (310,374) (4,513,093) (333,575) (4,296,208) --------------------------------------------------------------------------- Net increase 76,302 $ 1,170,200 562,872 $ 6,801,730 =========================================================================== - -------------------------------------------------------------------------------- 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 Fund which provides for a fee at an annual rate of 0.75% of the first $200 million of average annual net assets of the Fund, 0.72% of the next $200 million, 0.69% of the next $200 million, 0.66% of the next $200 million, 0.60% of the next $700 million, 0.58% of the next $1 billion, and 0.56% of average annual net assets in excess of $2.5 billion. - -------------------------------------------------------------------------------- ADMINISTRATION SERVICES. The Fund pays the Manager a fee of $1,500 per year for preparing and filing the Fund's tax returns. - -------------------------------------------------------------------------------- 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. For the six months ended April 30, 2004, the Fund paid $1,573,191 to OFS for services to the Fund. Additionally, Class Y shares are subject to minimum fees of $10,000 for assets of $10 million or more. The Class Y shares are subject to the minimum fees in the event that the per account fee does not equal or exceed the applicable minimum fees. OFS may voluntarily waive the minimum fees. OFS has voluntarily agreed to limit transfer and shareholder servicing agent fees for all classes to 0.35% of average annual net assets per class. This undertaking may be amended or withdrawn at any time. - -------------------------------------------------------------------------------- DISTRIBUTION AND SERVICE PLAN (12B-1) FEES. Under its General Distributor's Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor) acts as the Fund's principal underwriter in the continuous public offering of the Fund's classes of shares. 27 | OPPENHEIMER MIDCAP FUND - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan for Class A shares. It reimburses the Distributor for a portion of its costs incurred for services provided to accounts that hold Class A shares. Reimbursement is made quarterly at an annual rate of up to 0.25% of the average annual net assets of Class A shares of the Fund. The Distributor currently uses all of those fees to pay dealers, brokers, banks and other financial institutions quarterly for providing personal services and maintenance of accounts of their customers that hold Class A shares. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent years. Fees incurred by the Fund under the Plan are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund has adopted Distribution and Service Plans for Class B, Class C and Class N shares to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% per year on Class B shares and on Class C shares and 0.25% per year on Class N shares. The Distributor also receives a service fee of up to 0.25% per year under each plan. If either the Class B, Class C or Class N plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. The Distributor's aggregate uncompensated expenses under the plan at April 30, 2004 for Class B, Class C and Class N shares were $17,672,032, $3,569,075 and $340,975, respectively. Fees incurred by the Fund under the plans are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- SALES CHARGES. Front-end sales charges and contingent deferred sales charges (CDSC) do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, as applicable. The sales charges retained by the Distributor from the sale of shares and the CDSC retained by the Distributor on the redemption of shares is shown in the table below for the period indicated.

ILLIQUID OR RESTRICTED SECURITIES As of April 30, 2004, investments in securities included issues that are illiquid or restricted. Restricted securities are purchased in private placement transactions, are not registered under the Securities Act of 1933, may have contractual restrictions on resale, and are valued under methods approved by the Board of Trustees as reflecting fair value. A security may also be considered illiquid if it lacks a readily available market or if its valuation has not changed for a certain period of time. The Fund intends to invest no more than 15% of its net assets (determined at the time of purchase and reviewed periodically) in illiquid or restricted securities. Certain restricted securities, eligible for resale to qualified institutional investors, are not subject to that limitation. The aggregate value of illiquid or restricted securities subject to this limitation as of April 30, 2004 was $524,651, which represents 0.06% of the Fund's net assets, all of which are considered restricted.

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 April 30, 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.

Code of Ethics The registrant has adopted a code of ethics that applies to the registrant's principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions. Item 3. Audit Committee Financial Expert The Board of Trustees of the registrant has determined that the registrant does not have an audit committee financial expert serving on its Audit Committee. In this regard, no member of the Audit Committee was identified as having all of the technical attributes identified in Instruction 2(b) to Item 3 of Form N-CSR to qualify as an "audit committee financial expert," whether through the type of specialized education or experience described in that Instruction. The Board has concluded that while the members of the Audit Committee collectively have the necessary attributes and experience required to serve effectively as an Audit Committee, no single member possesses all of the required technical attributes through the particular methods of education or experience set forth in the Instructions to be designated as an audit committee financial expert. Item 4. Principal Accountant Fees and Services Not applicable to semiannual reports. Item 5. Not applicable Item 6. Schedule of Investments Not applicable Item 7. Not applicable Item 8. Not applicable Item 9. 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 trustees 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.
