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

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,

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

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)
and 1% (five-year). Because Class B shares convert to Class A shares 72 months
after purchase, the "since inception" 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.

CLASS Y shares of the Fund were first publicly offered on 11/28/05. Class Y
shares are offered only to certain institutional investors under special
agreement with the Distributor.

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


                   11 | OPPENHEIMER SENIOR FLOATING RATE FUND



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,
early withdrawal charges on redemptions; and redemption fees (if applicable);
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, 2008.

ACTUAL EXPENSES. The first section of the table provides information about
actual account values and actual expenses. You may use the information in this
section 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 first section
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 second section of the table
provides 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 for each class before expenses, which is
not the 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
loads or early withdrawal charges, or a $12.00 fee imposed annually on accounts
valued at less than $500.00 (subject to exceptions described in the Statement of
Additional Information). Therefore, the


                   12 | OPPENHEIMER SENIOR FLOATING RATE FUND



"hypothetical" section of the table is 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.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/365
(to reflect the one-half year period). Those annualized expense ratios,
excluding indirect expenses from affiliated fund, based on the 6-month period
ended January 31, 2008 are as follows:

CLASS     EXPENSE RATIOS
- ------------------------
Class A        1.05%
- ------------------------
Class B        1.65
- ------------------------
Class C        1.57
- ------------------------
Class Y        0.74

The expense ratios reflect reduction to 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 and reduction to custodian expenses, if
applicable.

1. Per share amounts calculated based on the average shares outstanding during
the period.

2. Assumes an investment on the business day before the first day of the fiscal
period, with all dividends and distributions reinvested in additional shares on
the reinvestment date, and repurchase at the net asset value calculated on the
last business day of the fiscal period. Total returns are not annualized for
periods less than one full year. Returns do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or the redemption of fund
shares.

3. Annualized for periods less than one full year.

4. Total expenses including indirect expenses from affiliated fund were as
follows:

       Six Months Ended January 31, 2008          1.15%
       Year Ended July 31, 2007                   1.07%

5. The previously reported portfolio turnover rate of 9% has been restated based
upon a calculation methodology that is consistent with the other periods
presented herein. This methodology includes certain loans that were previously
considered short-term, and therefore excluded from the calculation, due to an
interest rate reset feature.

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 securities. The Fund's investment adviser is
OppenheimerFunds, Inc. (the "Manager").

      The Fund offers Class A, Class B, Class C 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 and Class C shares are sold without an initial
sales charge but may be subject to an early withdrawal charge ("EWC"). Class Y
shares are sold to certain institutional investors without either a front-end
sales charge or a EWC, however, the institutional investor 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 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. No such plan has been adopted for Class Y shares. 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 trading. Securities may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Trustees. Securities traded on a registered U.S.
securities exchange 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 whose principal exchange is NASDAQ(R) are valued based on the closing
price reported 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 traded on foreign
exchanges are valued based on the last sale price on the principal exchange on
which the security is traded, as identified by the portfolio pricing service,
prior to the time when the Fund's assets are valued. In the absence of a sale,
the security is valued at the official closing price on the principal exchange.
Corporate, government and municipal debt instruments having a remaining maturity
in excess of sixty days and all mortgage-backed securities, collateralized
mortgage obligations and other asset-backed securities will be valued at the
mean between the "bid" and "asked" prices. Securities for which market
quotations are not readily available are valued at their fair value. Securities
whose values have been materially affected by what the Manager identifies as a
significant event occurring before the Fund's assets


                   38 | OPPENHEIMER SENIOR FLOATING RATE FUND



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. Shares of a
registered investment company that are not traded on an exchange are valued at
the acquired investment company's net asset value per share. "Money market-type"
debt instruments with remaining maturities of sixty days or less are valued at
cost adjusted by the amortization of discount or premium to maturity (amortized
cost), which approximates market value.

- --------------------------------------------------------------------------------
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 are often issued in connection with recapitalizations,
acquisitions, leveraged buyouts, and refinancing of borrowers. The Senior Loans
pay interest at rates that float above (or are adjusted periodically based on) a
benchmark that reflects current interest rates. 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, 2008, securities with an aggregate market value of
$2,576,257,426, representing 106.00% of the Fund's net assets were comprised of
Senior Loans, of which $821,124,082 representing 33.79% of the Fund's 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. As of January 31, 2008, securities with an
aggregate market value of $1,824,230, representing 0.08% of the Fund's net
assets, were in default.

- --------------------------------------------------------------------------------
INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Fund is permitted
to invest daily available cash balances in an affiliated money market fund. The
Fund may invest the available cash in Class E shares of Oppenheimer
Institutional Money Market Fund ("IMMF") to seek current income while preserving
liquidity. IMMF is a registered open-end management investment company,
regulated as a money market fund under the Investment Company Act of 1940, as
amended. The Manager is also the investment adviser of IMMF. The Fund's
investment in IMMF is included in the Statement of Investments. As a
shareholder, the Fund is subject to its proportional share of IMMF's Class E
expenses, including its management fee. The Manager will waive fees and/or
reimburse Fund expenses in an amount equal to the indirect management fees
incurred through the Fund's investment in IMMF.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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.

- --------------------------------------------------------------------------------
INVESTMENTS WITH OFF-BALANCE SHEET RISK. The Fund enters into financial
instrument transactions (such as swaps, futures, options and other derivatives)
that may have off-balance sheet market risk. Off-balance sheet market risk
exists when the maximum potential loss on a particular financial instrument is
greater than the value of such financial instrument, as reflected in the Fund's
Statement of Assets and Liabilities.

- --------------------------------------------------------------------------------
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. The Fund files income tax returns in U.S. federal and applicable state
jurisdictions. The statute of limitations on the Fund's tax return filings
generally remain open for the three preceding fiscal reporting period ends.

      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, 2008, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $140,594,785 expiring by
2016. 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. During the
six months ended January 31, 2008, it is estimated that the Fund will not
utilize any capital loss carryforward to offset realized capital gains. During
the fiscal year ended July 31, 2007, the Fund did not utilize any capital loss
carryforward to offset capital gains realized in that fiscal year.

As of July 31, 2007, the Fund had available for federal income tax purposes
post-October losses of $12,119,261 and unused capital loss carryforwards as
follows:

                                EXPIRING

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Board of Trustees has adopted a compensation
deferral 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 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 compensation deferral plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations and
may differ from U.S. generally accepted accounting principles, 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. 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 is recognized on an accrual basis. Market discount and
premium, which are included in interest income on the Statement of Operations,
are amortized or accreted daily.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
INDEMNIFICATIONS. The Fund's organizational documents provide current and former
trustees and officers with a limited indemnification against liabilities arising
in connection with the performance of their duties to the Fund. In the normal
course of business, the Fund may also enter into contracts that provide general
indemnifications. The Fund's maximum exposure under these arrangements is
unknown as this would be dependent on future claims that may be made against the
Fund. The risk of material loss from such claims is considered remote.

- --------------------------------------------------------------------------------
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 increases and
decreases in net assets from operations during the reporting period. Actual
results could differ from those estimates.

2. SHARES OF BENEFICIAL INTEREST

Each quarter the Fund intends to make a "Repurchase Offer" to repurchase a
portion of the Fund's outstanding shares from shareholders. The Repurchase
Offers are designed to provide some liquidity for Fund investors who wish to
sell some or all of their shares. 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 regular business day,
            then the repurchase pricing date will be the following 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, 2008, the Fund extended two Repurchase
Offers:

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

      Additionally, Class Y shares are subject to minimum fees of $10,000
annually 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.

- --------------------------------------------------------------------------------
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 (the
"Plan") for Class A shares under Rule 12b-1 of the Investment Company Act of
1940. Under the Plan, the Fund reimburses the Distributor for a portion of its
costs incurred for services provided to accounts that hold Class A shares.
Reimbursement is made periodically 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 periodically for providing personal service 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 periods. 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 (the "Plans") for Class B and Class C
shares under Rule 12b-1 of the Investment Company Act of 1940 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% on Class B and Class C shares. The Board of
Trustees has currently set that fee 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 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 Plans at December 31,
2007 for Class B and Class C shares were $7,443,031 and $39,405,804,
respectively. Fees incurred by the Fund under the Plans are detailed in the
Statement of Operations.

- --------------------------------------------------------------------------------
SALES CHARGES. Front-end sales charges and early withdrawal charges ("EWC") 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 EWC


                   44 | OPPENHEIMER SENIOR FLOATING RATE FUND



retained by the Distributor on the redemption of shares is shown in the
following table for the period indicated.

- --------------------------------------------------------------------------------
WAIVERS AND REIMBURSEMENTS OF EXPENSES. Effective January 1, 2006, the Manager
reduced its voluntary waiver of management fees from 0.20% of average annual net
assets to 0.10% of average annual net assets. As a result of this agreement, the
Fund was reimbursed $1,659,791 for the six months ended January 31, 2008. The
Manager may amend or terminate this 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 withdrawn at any time.

      The Manager will waive fees and/or reimburse Fund expenses in an amount
equal to the indirect management fees incurred through the Fund's investment in
IMMF. During the six months ended January 31, 2008, the Manager waived $56,098
for IMMF management fees.

      During the six months ended January 31, 2008, the Manager voluntarily
reimbursed the Fund $68,855 for certain transactions. The payment increased the
Fund's total return by less than 0.01%.

- --------------------------------------------------------------------------------
5. SWAP CONTRACTS

The Fund may enter into swap contract agreements with a counterparty to exchange
a series of cash flows based on either specified reference rates, or the
occurrence of a credit event, over a specified period. Such contracts may
include interest rate, equity, debt, index, total return, credit and currency
swaps.

      Swaps are marked to market daily using primarily quotations from pricing
services, counterparties and brokers. Swap contracts are reported on a schedule
following the Statement of Investments. The value of the contracts is separately
disclosed on the Statement of Assets and Liabilities. The unrealized
appreciation (depreciation) related to the change in the valuation of the
notional amount of the swap is combined with the accrued interest due to (owed
by) the Fund at termination or settlement. The net change in this amount during
the period is included on the Statement of Operations. The Fund also records any
periodic payments received from (paid to) the counterparty, including at
termination, under such contracts as realized gain (loss) on the Statement of
Operations.

      Risks of entering into swap contracts include credit, market and liquidity
risk. Credit risk arises from the possibility that the counterparty will
default. If the counterparty defaults, the Fund's loss will consist of the net
amount of contractual payments that the Fund has not yet received. Market risk
is the risk that the value of the contract will depreciate due to

unfavorable changes in the reference asset. If there is an illiquid market for
the agreement, the Fund may be unable to close the contract prior to contract
termination.

- --------------------------------------------------------------------------------
CREDIT DEFAULT SWAP CONTRACTS. A credit default swap is a bilateral contract
that enables an investor to buy or sell protection against a defined-issuer
credit event. The Fund may enter into credit default swaps on a single security,
or a basket of securities.

      In a credit default swap contract, the purchaser of the contract will pay
a periodic interest fee, similar to an insurance premium, on the notional amount
of the swap contract to the counterparty (the seller of the contract). If there
is a credit event (for example, bankruptcy or a failure to timely pay interest
or principal), the purchaser will exercise the contract and will receive a
payment from the seller of the contract equal to the notional value of the
credit default swap contract less the value of the underlying security. In the
event that the credit default swap is exercised due to a credit event, the
difference between the value of the underlying security and the notional amount
is recorded as realized gain (loss) and is included on the Statement of
Operations.

      Risks of credit default swaps include, but are not limited to, the cost of
paying for credit protection if there are no credit events, pricing transparency
when assessing the cost of a credit default swap, and the need to fund the
delivery obligation (either cash or defaulted securities).

- --------------------------------------------------------------------------------
6. ILLIQUID SECURITIES

As of January 31, 2008, investments in securities included issues that are
illiquid. Investments may be illiquid because they do not have an active trading
market, making it difficult to value them or dispose of them promptly at an
acceptable price. Securities that are illiquid are marked with an applicable
footnote on the Statement of Investments.

- --------------------------------------------------------------------------------
7. LOAN COMMITMENTS

Pursuant to the terms of certain credit agreements, the Fund can have unfunded
loan commitments. As of January 31, 2008, the Fund did not have any unfunded
loan commitments. The Fund generally will maintain with its custodian, liquid
investments having an aggregate value at least equal to the amount of unfunded
loan commitments.

- --------------------------------------------------------------------------------
8. BORROWINGS

The Fund can borrow money from banks in amounts up to one third of its total
assets (including the amount borrowed) less all liabilities and indebtedness
other than borrowings to purchase portfolio securities, to meet redemption
obligations or for temporary and emergency purposes. The purchase of securities
with borrowed funds creates leverage in the Fund. The use of leverage will
subject the Fund to greater costs than funds that do not borrow for leverage,
and may also make the Fund's share price more sensitive to interest changes. The
interest on borrowed money is an expense that might reduce the Fund's yield.


                   46 | OPPENHEIMER SENIOR FLOATING RATE FUND



Expenses incurred by the Fund with respect to interest on borrowings and
commitment fees are disclosed separately or as other expenses on the Statement
of Operations.

      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 $1,250,000,000, 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 (4.6038% as of January 31, 2008). The Fund pays
additional fees annually to its lender on its outstanding borrowings to manage
and administer the facility and is allocated its pro-rata share of an annual
commitment fee on the amount of the unused portion of total facility size. The
Fund has the right to prepay such loans and terminate its participation in the
conduit loan facility at any time upon prior notice.

For the six months ended January 31, 2008, the Fund had borrowings outstanding
at an interest rate of 4.6038%. Details of the borrowings for the six months
ended January 31, 2008, are listed in the following table.

                Average Daily Loan Balance     $87,604,348
                Average Daily Interest Rate          5.206%
                Fees Paid                      $   332,600
                Interest Paid                  $ 2,720,911

As of January 31, 2008, the Fund had no borrowings outstanding.

- --------------------------------------------------------------------------------
9. RECENT ACCOUNTING PRONOUNCEMENT

In September 2006, Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 157, FAIR VALUE
MEASUREMENTS. This standard establishes a single authoritative definition of
fair value, sets out a framework for measuring fair value and expands
disclosures about fair value measurements. SFAS No. 157 applies to fair value
measurements already required or permitted by existing standards. SFAS No. 157
is effective for financial statements issued for fiscal years beginning after
November 15, 2007, and interim periods within those fiscal years. As of January
31, 2008, the Manager does not believe the adoption of SFAS No. 157 will
materially impact the financial statement amounts; however, additional
disclosures may be required about the inputs used to develop the measurements
and the effect of certain of the measurements on changes in net assets for the
period.

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Fund's
investment advisory agreement (the "Agreement"). The Investment Company Act of
1940, as amended, requires that the Board request and evaluate, and that the
Manager provide, such information as may be reasonably necessary to evaluate the
terms of the Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information, that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services, (v) whether economies of scale
are realized as the Fund grows and whether fee levels reflect these economies of
scale for Fund investors and (vi) other benefits to the Manager from its
relationship with the Fund. Outlined below is a summary of the principal
information considered by the Board as well as the Board's conclusions.

      The Board was aware that there are alternatives to retaining the Manager.

      NATURE, QUALITY, AND EXTENT OF SERVICES. The Board considered information
about the nature and extent of the services provided to the Fund and information
regarding the Manager's key personnel who provide such services. The Manager's
duties include providing the Fund with the services of the portfolio managers
and the Manager's investment team, who provide research, analysis and other
advisory services in regard to the Fund's investments; securities trading
services; oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.


                   48 | OPPENHEIMER SENIOR FLOATING RATE FUND



      The Board also considered the quality of the services provided and the
quality of the Manager's resources that are available to the Fund. The Board
took account of the fact that the Manager has had over forty years of experience
as an investment adviser and that its assets under management rank it among the
top mutual fund managers in the United States. The Board evaluated the Manager's
administrative, accounting, legal and compliance services, and information the
Board has received regarding the experience and professional qualifications of
the Manager's key personnel and the size and functions of its staff providing
investment management services to the Fund. In its evaluation of the quality of
the portfolio management services provided, the Board considered the experience
of Arthur Zimmer, Joesph Welsh, and Margaret Hui. Messrs. Zimmer and Welsh have
been portfolio managers of the Fund since September 1999, and Ms. Hui has been a
portfolio manager of the Fund since October 1999. The Board members also
considered the totality of their experiences with the Manager as directors or
trustees of the Fund and other funds advised by the Manager. In light of the
foregoing, the Board concluded that the Fund benefits from the services provided
under the Agreement as a result of the Manager's experience, reputation,
personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the investment performance of the Fund and the
Manager at each Board meeting, including comparative performance information.
The Board also reviewed information, prepared by the Manager and by the
independent consultant, comparing the Fund's historical performance to relevant
market indices and to the performance of other nonleveraged closed-end loan
participation funds. The Board noted that the Fund's one-year performance was
better than its peer group median and its three-year and five-year performance
was equal to its peer group median.

      COSTS OF SERVICES AND PROFITS REALIZED BY THE MANAGER. The Board
considered information regarding the Manager's costs in serving as the Fund's
investment adviser, including the costs associated with the personnel and
systems necessary to manage the Fund, and information regarding the Manager's
profitability from its relationship with the Fund. The Board reviewed the fees
paid to the Manager and the other expenses borne by the Fund. The Board also
considered the comparability of the fees charged and the services provided to
the Fund to the fees and services for other clients or accounts advised by the
Manager. The independent consultant provided comparative data in regard to the
fees and expenses of the Fund, other nonleveraged closed-end loan participation
funds. The Board noted that the Manager has agreed to voluntarily waive fees its
management fee by 0.10% of average annual net assets. This waiver may

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited / Continued
- --------------------------------------------------------------------------------

be withdrawn or amended at any time. The Board noted that the Fund's contractual
and actual management fees are lower than its peer group median.

      ECONOMIES OF SCALE. The Board reviewed whether the Manager may realize
economies of scale in managing and supporting the Fund. The Board noted that the
Fund currently has management fee breakpoints, which are intended to share with
Fund shareholders economies of scale that may exist as the Fund's assets grow.

      OTHER BENEFITS TO THE MANAGER. In addition to considering the profits
realized by the Manager, the Board considered information that was provided
regarding the direct and indirect benefits the Manager receives as a result of
its relationship with the Fund, including compensation paid to the Manager's
affiliates. The Board also considered that the Manager must be able to pay and
retain experienced professional personnel at competitive rates to provide
quality services to the Fund and that maintaining the financial viability of the
Manager is important in order for the Manager to continue to provide significant
services to the Fund and its shareholders.

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and to the independent Trustees. Fund counsel and the independent
Trustees' counsel are both independent of the Manager within the meaning and
intent of the Securities and Exchange Commission Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
decided to continue the Agreement for another year. In arriving at this
decision, the Board considered all of the above information, and considered the
terms and conditions of the Agreement, including the management fee, in light of
all of the surrounding circumstances.

ITEM 10.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

THE FUND'S  GOVERNANCE  COMMITTEE  PROVISIONS  WITH  RESPECT TO  NOMINATIONS  OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.   The Fund's Governance Committee (the "Committee") will evaluate potential
     Board candidates to assess their qualifications. The Committee shall have
     the authority, upon approval of the Board, to retain an executive search
     firm to assist in this effort. The Committee may consider recommendations
     by business and personal contacts of current Board members and by executive
     search firms which the Committee may engage from time to time and may also
     consider shareholder recommendations. The Committee may consider the advice
     and recommendation of the Funds' investment manager and its affiliates in
     making the selection.

2.   The Committee shall screen candidates for Board membership. The Committee
     has not established specific qualifications that it believes must be met by
     a trustee nominee. In evaluating trustee nominees, the Committee considers,
     among other things, an individual's background, skills, and experience;
     whether the individual is an "interested person" as defined in the
     Investment Company Act of 1940; and whether the individual would be deemed
     an "audit committee financial expert" within the meaning of applicable SEC
     rules. The Committee also considers whether the individual's background,
     skills, and experience will complement the background, skills, and
     experience of other nominees and will contribute to the Board. There are no
     differences in the manner in which the Committee evaluates nominees for
     trustees based on whether the nominee is recommended by a shareholder.

3.   The Committee may consider nominations from shareholders for the Board at
     such times as the Committee meets to consider new nominees for the Board.
     The Committee shall have the sole discretion to determine the candidates to
     present to the Board and, in such cases where required, to shareholders.
     Recommendations for trustee nominees should, at a minimum, be accompanied
     by the following:

     o    the name, address, and business, educational, and/or other pertinent
          background of the person being recommended;

     o    a statement concerning whether the person is an "interested person" as
          defined in the Investment Company Act of 1940;

     o    any other information that the Funds would be required to include in a
          proxy statement concerning the person if he or she was nominated; and

     o    the name and address of the person submitting the recommendation and,
          if that person is a shareholder, the period for which that person held
          Fund shares.


     The recommendation also can include any additional information which the
     person submitting it believes would assist the Committee in evaluating the
     recommendation.

4.   Shareholders should note that a person who owns securities issued by
     Massachusetts Mutual Life Insurance Company (the parent company of the
     Funds' investment adviser) would be deemed an "interested person" under the
     Investment Company Act of 1940. In addition, certain other relationships
     with Massachusetts Mutual Life Insurance Company or its subsidiaries, with
     registered broker-dealers, or with the Funds' outside legal counsel may
     cause a person to be deemed an "interested person."

5.   Before the Committee decides to nominate an individual as a trustee,
     Committee members and other directors customarily interview the individual
     in person. In addition, the individual customarily is asked to complete a
     detailed questionnaire which is designed to elicit information which must
     be disclosed under SEC and stock exchange rules and to determine whether
     the individual is subject to any statutory disqualification from serving as
     a trustee of a registered investment company.


ITEM 11.  CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 01/31/2008, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
