NOTES
- --------------------------------------------------------------------------------


Total returns include changes in share price and reinvestment of dividends and
capital gains distributions in a hypothetical investment for the periods shown.
Cumulative total returns are not annualized. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares. INVESTORS SHOULD CONSIDER THE
FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER CHARGES AND EXPENSES CAREFULLY
BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS THIS AND OTHER INFORMATION
ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR FINANCIAL ADVISOR, CALLING US
AT 1.800.525.7048 OR VISITING OUR WEBSITE AT WWW.OPPENHEIMERFUNDS.COM. READ THE
PROSPECTUS CAREFULLY BEFORE INVESTING.

The Fund's investment strategy and focus can change over time. The mention of
specific fund holdings does not constitute a recommendation by OppenheimerFunds,
Inc.

OPPENHEIMER SENIOR FLOATING RATE FUND IS A CONTINUOUSLY OFFERED CLOSED-END FUND
WHOSE SHARES ARE NOT LISTED ON ANY STOCK EXCHANGE OR NATIONAL QUOTATION SERVICE.
THE FUND'S SHARES ARE NOT REDEEMABLE FOR CASH DAILY BUT THE FUND SEEKS TO
PROVIDE A DEGREE OF LIQUIDITY TO SHAREHOLDER BY MAKING QUARTERLY OFFERS TO
REPURCHASE A PORTION OF THE FUND'S SHARES. HOWEVER, THERE CAN BE NO ASSURANCE
THAT THE FUND WILL BE ABLE TO REPURCHASE ALL SHARES TENDERED IN A PARTICULAR
REPURCHASE OFFER. SHARES OF THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF ANY
BANK, ARE NOT GUARANTEED BY ANY BANK, ARE NOT INSURED BY THE FDIC OR ANY OTHER
AGENCY, AND INVOLVE INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS OF THE
PRINCIPAL AMOUNT INVESTED. SHARES OF THE FUND WILL FLUCTUATE AND THE FUND IS NOT
A MONEY MARKET FUND.

Please note that Oppenheimer Senior Floating Rate Fund has a limited operating
history. The inception date of all classes is 9/8/99. Therefore you should not
consider the performance shown to be indicative of long-term results. The Fund
is not intended as an investor's only investment, but to complement other
holdings.


9 | OPPENHEIMER SENIOR FLOATING RATE FUND


NOTES
- --------------------------------------------------------------------------------


CLASS A shares of the Fund were first publicly offered on 9/8/99. Unless
otherwise noted, Class A returns include the current maximum initial sales
charge of 3.50%.

CLASS B shares of the Fund were first publicly offered on 9/8/99. Class B total
returns are shown net of the applicable early withdrawal charge of 3%
(one-year). Because Class B shares convert to Class A shares 72 months after
purchase, the life of class return for Class B uses Class A performance for the
period after conversion. Class B shares are subject to an annual 0.50%
asset-based sales charge.

CLASS C shares of the Fund were first publicly offered on 9/8/99. Class C shares
are shown net of the applicable 1% early withdrawal charge for the one-year
period. Class C shares are subject to an annual 0.50% asset-based sales charge.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

FUND EXPENSES
- --------------------------------------------------------------------------------


FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and service fees;
and other Fund expenses. These examples are intended to help you understand your
ongoing costs (in dollars) of investing in the Fund 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 January 31, 2005.

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 for the class of shares you hold, 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 Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund'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 Fund 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.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in

FUND EXPENSES
- --------------------------------------------------------------------------------


the Statement of Additional Information). Therefore, the "hypothetical" lines of
the table are useful in comparing ongoing costs only, and will not help you
determine the relative total costs of owning different funds. In addition, if
these transactional costs were included, your costs would have been higher.

Class C Hypothetical          1,000.00         1,018.20        7.02

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/366
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended January 31, 2005 are as follows:

CLASS     EXPENSE RATIOS
- -------------------------
Class A        0.88%
- -------------------------
Class B        1.44
- -------------------------
Class C        1.38

The expense ratios reflect voluntary waivers or reimbursements of expenses by
the Fund's Manager that can be terminated at any time, without advance notice.
The "Financial Highlights" tables in the Fund's financial statements, included
in this report, also show the gross expense ratios, without such waivers or
reimbursements.

NOTES TO FINANCIAL STATEMENTS  Unaudited
- --------------------------------------------------------------------------------


- --------------------------------------------------------------------------------
 1. SIGNIFICANT ACCOUNTING POLICIES
 Oppenheimer Senior Floating Rate Fund (the Fund) is registered under the
 Investment Company Act of 1940, as amended, as a closed-end management
 investment company. The Fund seeks as high a level of current income and
 preservation of capital as is consistent with investing primarily in senior
 floating rate loans and other debt obligations. The Fund's investment advisor
 is OppenheimerFunds, Inc. (the Manager).
    The Fund offers Class A, Class B and Class C shares. Class A shares are sold
 at their offering price, which is normally net asset value plus a front-end
 sales charge. Class B and Class C shares are sold without an initial sales
 charge but may be subject to an Early Withdrawal Charge. 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 due to each class having
 its own expenses, such as transfer and shareholder servicing agent fees and
 shareholder communications, directly attributable to that class. Class A, B and
 C shares have separate distribution and/or service plans. Class B shares will
 automatically convert to Class A shares 72 months after the end of the month in
 which you purchase them.
    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. Corporate, government and municipal debt instruments having a remaining
 maturity in excess of sixty days and all mortgage-backed securities will be
 valued at the mean between the "bid" and "asked" prices. 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 and domestic 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 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).



38 | OPPENHEIMER SENIOR FLOATING RATE FUND



- --------------------------------------------------------------------------------
 WHEN-ISSUED AND DELAYED DELIVERY SECURITY TRANSACTIONS. The Fund purchases and
 sells interests in Senior Loans and other portfolio securities on a "when
 issued" and "delayed delivery" basis. No income accrues to the Fund on such
 interests or securities in connection with such purchase transactions prior to
 the date the Fund actually takes delivery of such interest or securities. These
 transactions are subject to market fluctuation; the value of the interests in
 Senior Loans and other portfolio debt securities at delivery may be more or
 less than their purchase prices, and yields generally available on such
 interests or securities when delivery occurs may be higher or lower than yields
 on the interest or securities obtained pursuant to such transactions. Because
 the Fund relies on the buyer or seller to consummate the transaction, failure
 by the other party to complete the transaction may result in the Fund missing
 the opportunity of obtaining a price or yield considered to be advantageous.
 When the Fund is the buyer in such a transaction, it will maintain, in a
 segregated account with its custodian, cash or liquid securities having an
 aggregate value equal to the amount of such purchase commitments until payment
 is made. To the extent the Fund engages in "when issued" and "delayed delivery"
 purchases, it will do so for the purpose of acquiring interest or securities
 for the Fund's portfolio consistent with the Fund's investment objective and
 policies and not for the purpose of investment leverage.

- --------------------------------------------------------------------------------
 SENIOR LOANS. Under normal market conditions, the Fund will invest at least 80%
 of its net assets (plus borrowings for investment purposes) in floating rate
 Senior Loans made to U.S. and foreign borrowers that are corporations,
 partnerships or other business entities. The Fund will do so either as an
 original lender or as a purchaser of a loan assignment or a participation
 interest in a loan.While most of these loans will be collateralized, the Fund
 can also under normal market conditions invest up to 10% of its net assets
 (plus borrowings for investment purposes) in uncollateralized floating rate
 Senior Loans.
    Senior Loans generally are not listed on any national securities exchange or
 automated quotation system and no active trading market exists for many Senior
 Loans. As a result, many Senior Loans are illiquid, meaning the Fund may not be
 able to value them accurately or to sell them quickly at a fair price. To the
 extent that a secondary market does exist for certain Senior Loans, the market
 may be subject to irregular trading activity, wide bid/ask spreads and extended
 trade settlement periods.
    As of January 31, 2005, securities with an aggregate market value of
 $2,233,527,928, representing 105.1% of the Fund's net assets were comprised of
 Senior Loans, of which $1,681,643,006 representing 79.15% of net assets, were
 illiquid.

- --------------------------------------------------------------------------------
 SECURITY CREDIT RISK. Senior Loans are subject to credit risk. Credit risk
 relates to the ability of the borrower under a Senior Loan to make interest and
 principal payments as they become due. The Fund's investments in Senior Loans
 are subject to risk of default.

- --------------------------------------------------------------------------------
 REPURCHASE AGREEMENTS. The Fund requires its custodian bank to take possession,
 to have legally segregated in the Federal Reserve Book Entry System or to have
 segregated

NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued
- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------
 1. SIGNIFICANT ACCOUNTING POLICIES Continued
 within the custodian's vault, all securities held as collateral for repurchase
 agreements. The market value of the underlying securities is required to be at
 least 102% of the resale price at the time of purchase. If the seller of the
 agreement defaults and the value of the collateral declines, or if the seller
 enters an insolvency proceeding, realization of the value of the collateral by
 the Fund may be delayed or limited.

- --------------------------------------------------------------------------------
 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 January 31, 2005, the Fund had available for federal income tax
 purposes an estimated capital loss carryforward of $37,305,263 expiring by
 2013. 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 is increased or decreased by
 capital losses or gains realized in the first six months of the current fiscal
 year. As of January 31, 2005, it is estimated that the Fund will utilize
 $2,529,479 of capital loss carryforward to offset realized capital gains.
 During the year ended July 31, 2004, the Fund did utilize $1,064,614 of capital
 loss carryforward to offset realized capital gains.

 As of July 31, 2004, the Fund had available for federal income tax purposes
 post-October losses of $484,476 and unused capital loss carryforwards as
 follows:
                              EXPIRING
                              ----------------------
                              2010       $13,831,444
                              2011        26,003,298
                                         -----------
                              Total      $39,834,742
                                         ===========

- --------------------------------------------------------------------------------
 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. For



40 | OPPENHEIMER SENIOR FLOATING RATE FUND


 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
 purchases 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 distributions, if any, are
 declared daily and paid monthly. Capital gain distributions, if any, are
 declared and paid annually.

- --------------------------------------------------------------------------------
 INVESTMENT INCOME. Interest income, which includes accretion of discount and
 amortization of premium, is accrued as earned. 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. Other income is comprised primarily of
 amendment fees which are recorded when received. Amendment fees are earned as
 compensation for agreeing to changes in loan agreements.

- --------------------------------------------------------------------------------
 CUSTODIAN FEES. Custodian Fees and Expenses in the Statement of Operations may
 include interest expense incurred by the Fund 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 Fund pays
 interest to its custodian on such cash overdrafts 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 Fund
 during the period. Such interest expense and other custodian fees may be paid
 with these earnings.

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

 2. SHARES OF BENEFICIAL INTEREST
 The Fund has adopted the following fundamental policies concerning periodic
 repurchase offers:
    o  The Fund will make periodic Repurchase Offers, pursuant to Rule 23c-3
       under the Investment Company Act of 1940 (as that rule may be amended
       from time to time).
    o  Repurchase offers shall be made at periodic intervals of three months
       between Repurchase Request Deadlines. The Deadlines will be at the time
       on a regular business day (normally the last regular business day) in the
       months of January, April, July and October to be determined by the Fund's
       Board of Trustees.
    o  The Repurchase Pricing Date for a particular Repurchase Offer shall be
       not more than 14 days after the Repurchase Request Deadline for the
       Repurchase Offer. If that day is not a normal business day, then the
       Repurchase Pricing Date will be the following regular business day.
    Each quarter, the Fund's Board will determine the number of shares that the
 Fund will offer to repurchase in a particular Repurchase Offer. The Repurchase
 Offer Amount will be at least 5% but not more than 25% of the total number of
 shares of all classes of the Fund (in the aggregate) outstanding on the
 Repurchase Request Deadline. If shareholders tender more than the Repurchase
 Offer Amount for a particular Repurchase Offer, the Fund may repurchase up to
 an additional 2% of the shares outstanding on the Repurchase Request Deadline.

 For the six months ended January 31, 2005, the Fund extended two Repurchase
 Offers:

 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 January 31, 2005, were
 $1,914,428,751 and $1,049,284,896, respectively.


- --------------------------------------------------------------------------------
 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 0.75% 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, and 0.60% of average annual net assets in excess of
 $800 million.

- --------------------------------------------------------------------------------
 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 January 31, 2005, the
 Fund paid $625,079 to OFS for services to the Fund.

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

- --------------------------------------------------------------------------------
 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

 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued
 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 AND CLASS C SHARES. The Fund has
 adopted Distribution and Service Plans for Class B and Class C 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 a distribution fee (which is deemed to be an "asset-based sales
 charge") of up to 0.75% of average annual net assets on Class B shares and on
 Class C shares. The Board of Trustees has currently set that fee rate at 0.50%
 of average annual net assets of the respective class per year under each plan
 but may increase it up to 0.75% in the future. The Distributor also receives a
 service fee of up to 0.25% per year under each plan. If either the Class B or
 Class C 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 January 31, 2005 for Class B and Class
 C shares were $6,407,578 and $18,582,302, 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.

 PAYMENTS AND WAIVERS OF EXPENSES. The Manager has voluntarily agreed to reduce
 its management fee by 0.20% of average annual net assets. As a result of this
 agreement, the Fund was reimbursed $1,722,620 for the six months ended January
 31, 2005. It can amend or terminate that voluntary waiver at any time.
    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 terminated at any time.

- --------------------------------------------------------------------------------
 5. ILLIQUID SECURITIES
 As of January 31, 2005, 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. Most
 Senior Loans and many of the Fund's other investments are illiquid.


- --------------------------------------------------------------------------------
 6. LOAN COMMITMENTS
 Pursuant to the terms of certain credit agreements, the Fund has unfunded loan
 commitments of $18,548,429 at January 31, 2005. These commitments are subject
 to funding based on the borrower's discretion. The Fund is obligated to fund
 these commitments at the time of the request by the borrower. The Fund
 generally will maintain with its custodian, short-term investments having an
 aggregate value at least equal to the amount of unfunded loan commitments.


- --------------------------------------------------------------------------------
 7. BORROWINGS
 The Fund can borrow money in an amount up to 33 1/3% of its total assets (after
 counting the assets purchased with the amount borrowed). The Fund may borrow if
 necessary to obtain short-term credit to allow it to repurchase shares during
 Repurchase Offers, to manage cash flows, and to fund additional purchase
 commitments under Senior Loans. The Fund may also borrow to acquire additional
 investments (a technique known as "leverage"). Until terminated on January 21,
 2005, the Fund had entered into an agreement which enabled it to participate
 with certain other Oppenheimer funds in a committed, unsecured line of credit
 with a bank, which permitted borrowings up to $540 million, collectively, of
 which commitment $80 million was allocated to the Fund. Interest was charged to
 each fund, based on its borrowings, at a rate equal to the Federal Funds Rate
 plus 0.75%. The Fund also paid a commitment fee equal to its pro rata share of
 the average unutilized amount of the credit facility at a rate of 0.09% per
 annum.
    Effective January 21, 2005, the Fund entered into a Revolving Credit and
 Security Agreement (the "Agreement") with a conduit lender and a bank which
 enables it to participate with certain other Oppenheimer funds in a committed,
 secured borrowing facility that permits borrowings of up to $800 million,
 collectively. To secure the loan, the Fund pledges investment securities in
 accordance with the terms of the Agreement. Interest is charged to the Fund,
 based on its borrowings, at current commercial paper issuance rates (2.4038% as
 of January 31, 2005). The Fund pays additional fees of 0.30% per annum on its
 outstanding borrowings to manage and administer the facility and is allocated
 its pro-rata share of a 0.13% per annum commitment fee for a liquidity backstop
 facility with respect to the $800 million facility size.
    For the six month period ended January 31, 2005, the average daily loan
 balance was $11,668,478 at an average daily interest rate of 2.515%. The Fund
 had no borrowings outstanding at January 31, 2005. The Fund had gross
 borrowings and gross loan repayments

- --------------------------------------------------------------------------------
 7. BORROWINGS Continued
 of $320,200,000 and $333,000,000, respectively, during the six months ended
 January 31, 2005. The maximum amount of borrowings outstanding at any month-end
 during the six month period ended January 31, 2005 was $3,000,000. The Fund
 paid $11,669 in fees and $150,222 in interest during the six months ended
 January 31, 2005.


- --------------------------------------------------------------------------------
 8. LITIGATION
 A consolidated amended complaint has been filed as putative derivative and
 class actions against the Manager, OFS and the Distributor (collectively, the
 "Oppenheimer defendants"), as well as 51 of the Oppenheimer funds (as "Nominal
 Defendants") including the Fund, 31 present and former Directors or Trustees
 and 9 present and former officers of the funds. This complaint, initially filed
 in the U.S. District Court for the Southern District of New York on January 10,
 2005 and amended on March 4, 2005, consolidates into a single action and amends
 six individual previously-filed putative derivative and class action
 complaints. Like those prior complaints, the complaint alleges that the Manager
 charged excessive fees for distribution and other costs, improperly used assets
 of the funds in the form of directed brokerage commissions and 12b-1 fees to
 pay brokers to promote sales of the funds, and failed to properly disclose the
 use of assets of the funds to make those payments in violation of the
 Investment Company Act of 1940 and the Investment Advisers Act of 1940. Also,
 like those prior complaints, the complaint further alleges that by permitting
 and/or participating in those actions, the Directors/Trustees and the Officers
 breached their fiduciary duties to shareholders of the funds under the
 Investment Company Act of 1940 and at common law. The complaint seeks
 unspecified compensatory and punitive damages, rescission of the funds'
 investment advisory agreements, an accounting of all fees paid, and an award of
 attorneys' fees and litigation expenses.
    The Oppenheimer defendants believe that the allegations contained in the
 Complaints are without merit and that they, the funds named as Nominal
 Defendants, and the Directors/Trustees of those funds have meritorious defenses
 against the claims asserted. The Oppenheimer defendants intend to defend these
 lawsuits vigorously and to contest any claimed liability. The Oppenheimer
 defendants believe that it is premature to render any opinion as to the
 likelihood of an outcome unfavorable to them and that no estimate can yet be
 made with any degree of certainty as to the amount or range of any potential
 loss.

ITEM 9.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         The registrant's Board of Trustees has established a Governance
Committee, one function of which is to create and oversee the process by which
shareholders can submit nominees for positions on the Board. The Governance
Committee has not yet adopted a charter, but anticipates that it will do so by
the end of this calendar year. The Committee has temporarily adopted the process
previously adopted by the Audit Committee regarding shareholder submission of
nominees for board positions. Shareholders may submit names of individuals,
accompanied by complete and properly supported resumes, for the Governance
Committee's consideration by mailing such information to the Committee in care
of the Fund. The Committee may consider such persons at such time as it meets to
consider possible nominees. The Committee, however, reserves solo discretion to
determine the candidates for trustees and independent trustees to recommend to
the Board and/or shareholders and may identify candidates other than those
submitted by Shareholders. The Committee may, but need not, consider the advice
and recommendation of the Manager and its affiliates in selecting nominees. The
full Board elects new trustees except for those instances when a shareholder
vote is required.

         Shareholders who desire to communicate with the Board should address
correspondence to the Board of Trustees of the registrant, or to an individual
Trustee c/o the Secretary of the Fund at 6803 South Tucson Way, Centennial,
Colorado 80112 and may submit their correspondence electronically at
WWW.OPPENHEIMERFUNDS.COM under the caption "contact us." If your correspondence
is intended for a particular Trustee, please indicate the name of the Trustee
for whom it is intended. The sender should indicate in the address whether it is
intended for the entire board, the Independent Trustees as group, or to an
individual Trustee. The Governance Committee will consider if a different
process should be recommended to the Board.



ITEM 10.  CONTROLS AND PROCEDURES

         (a)  Based on their evaluation of 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 January 31, 2005,
              registrant's principal executive officer and principal financial
              officer found registrant's disclosure controls and procedures to
              provide reasonable assurances that information required to be
              disclosed by 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.

         (b)  There have been no significant changes in registrant's internal
              controls over financial reporting that occurred during the
              registrant's last fiscal half-year that has materially affected,
              or is reasonably likely to materially affect, the registrant's
              internal control over financial reporting.
