 1. Significant Accounting Policies
 Oppenheimer Select Managers Mercury Advisors Focus Growth Fund (the Fund) is a
 separate series of Oppenheimer Select Managers, a non-diversified, open-end
 management investment company registered under the Investment Company Act of
 1940, as amended. The Fund invests substantially all of its assets in the
 Master Focus Twenty Trust (the Trust), a registered open-end investment company
 that has the same goals as the Fund. The financial statements of the Trust are
 included elsewhere in this report and should be read with the Fund's financial
 statements. The percentage of the Trust owned by the Fund at May 31, 2003 was
 2.05%. As of May 31, 2003, the total return for the Master Focus Twenty Fund
 was 8.29%. The Fund's investment objective is to seek long-term capital
 appreciation. The Fund's administrator 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. 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 records its investment in the Trust at fair
 value. Valuation of securities held by the Trust is discussed in the notes to
 Master Focus Twenty Trust included elsewhere in this report.

- --------------------------------------------------------------------------------
 Allocation of Income, Expenses, Gains and Losses. The Fund records daily its
 proportionate share of the Trust's income, expenses and realized and unrealized
 gains and losses. In addition, the Fund accrues its own expenses.

- --------------------------------------------------------------------------------
 Federal Taxes. The Fund 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, 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 May 31, 2003, the Fund had available for federal income tax purposes
 an estimated unused capital loss carryforward of $1,360,305. This estimated
 capital 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 increased or decreased by capital losses or gains
 realized in the first six months of the current fiscal year. During the six
 months ended May 31, 2003, the Fund used $465,326 of carryforward to offset
 capital gains realized. During the year ended November 30, 2002, the Fund did
 not use carryforward to offset capital gains realized.

 As of November 30, 2002, the Fund had available for federal income tax purposes
 unused capital loss carryovers 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.

- --------------------------------------------------------------------------------
 Classification of Dividends and Distributions to Shareholders. 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

13 OPPENHEIMER SELECT MANAGERS MERCURY ADVISORS FOCUS GROWTH FUND

NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued

- --------------------------------------------------------------------------------
 1. Significant Accounting Policies Continued
 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.
    No distributions were paid during the six months ended May 31, 2003 and the
 year ended November 30, 2002.

- --------------------------------------------------------------------------------
 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.

- --------------------------------------------------------------------------------
 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:

 4. Borrowing and Lending Arrangements
 Interfund Borrowing and Lending Arrangements. Commencing November 12, 2002, 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 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. 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 investment 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 May 31, 2003.

- --------------------------------------------------------------------------------
 5. Fund Reorganization
 In April, 2003, the Board of Trustees approved the reorganization of
 Oppenheimer Select Managers Mercury Advisors Focus Growth Fund with and into
 Oppenheimer Main Street Fund. Shareholders of Oppenheimer Select Managers
 Mercury Advisors Focus Growth Fund will be asked to approve a reorganization
 whereby shareholders would receive shares of Oppenheimer Main Street Fund. If
 shareholder approval is received, it is expected that the reorganization will
 occur during the fourth quarter of calendar 2003.
