Portfolio holdings and allocations are subject to change. Percentages are as of
June 30, 2007, and are dollar-weighted based on percentages of commodity-linked
securities. Commodity-linked securities are investments whose return is based
upon the price movements (whether up or down) of a particular commodity or
basket of commodities. The Fund's allocation of its investments within each
sector of the GSCI may differ (at times, significantly) from the sector
weightings of the GSCI. The Fund is not an index fund.

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.

Please note that Oppenheimer Commodity Strategy Total Return Fund is
non-diversified and invests a substantial portion of its assets in derivative
instruments that entail potentially higher volatility and risk of loss than
traditional equity or debt securities. The Fund is not intended as a complete
investment program and is intended for investors with long-term investment goals
who are willing to accept this risk.

CLASS A shares of the Fund were first publicly offered on 3/31/97. Class A
returns include the current maximum initial sales charge of 5.75%.

CLASS B shares of the Fund were first publicly offered on 3/31/97. Class B
returns include the applicable contingent deferred sales charge of 5% (1-year)
and 2% (5-year). Because Class B shares convert to Class A shares 72 months
after purchase, the 10-year return for Class B uses Class A performance for the
period after conversion. Class B shares are subject to an annual 0.75%
asset-based sales charge.

CLASS C shares of the Fund were first publicly offered on 3/31/97. Class C
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class C shares are subject to an annual 0.75% asset-based sales charge.

CLASS N shares of the Fund were first publicly offered on 3/1/01. Class N shares
are offered only through retirement plans. Unless otherwise noted, Class N
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class N shares are subject to an annual 0.25% asset-based sales charge.

CLASS Y shares of the Fund were first publicly offered on 3/31/97. Class Y
shares are offered principally to certain institutional investors under special
agreement with the Distributor and are not subject to a 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 June 30, 2007.

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), redemption fees, or a $12.00 fee
imposed annually on accounts valued at less than $500.00 (subject to


              13 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



FUND EXPENSES  Continued
- --------------------------------------------------------------------------------

exceptions described in 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 Y Hypothetical               1,000.00     1,021.72      3.11

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 181/365
(to reflect the one-half year period). Those annualized expense ratios,
excluding indirect expenses from affiliated fund, based on the 6-month period
ended June 30, 2007 are as follows:

CLASS                EXPENSE RATIOS
- -----------------------------------
Class A                   1.11%
- -----------------------------------
Class B                   2.01
- -----------------------------------
Class C                   1.95
- -----------------------------------
Class N                   1.51
- -----------------------------------
Class Y                   0.62

The expense ratio reflects reduction to custodian fees and voluntary waiver or
reimbursement by the Fund's Advisor and Transfer Agent 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.

FOOTNOTES TO STATEMENT OF INVESTMENTS

1. Non-income producing security.

2. Investment in a wholly-owned subsidiary. See Note 1 of accompanying Notes and
individual financial statements of the entity included herein beginning on page
52.

3. Represents the current interest rate for a variable or increasing rate
security.

4. Illiquid security. The aggregate value of illiquid securities as of June 30,
2007 was $388,204, which represents 0.03% of the Fund's net assets. See Note 7
of accompanying Notes.

5. Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows. These securities amount to $3,706,774 or 0.29% of the Fund's net assets
as of June 30, 2007.

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, 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, 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 Fund assesses a 2% fee on the proceeds of
fund shares that are redeemed (either by selling or exchanging to another
Oppenheimer fund) within 30 days of their purchase. The fee, which is retained
by the Fund, is accounted for as an addition to paid-in capital.

      The following is a summary of significant accounting policies consistently
followed by the Fund.

- --------------------------------------------------------------------------------
INVESTMENT IN RAF FUND LTD. The Fund may invest up to 25% of its total assets in
RAF Fund Ltd., a wholly-owned and controlled Cayman Islands subsidiary (the
"Subsidiary"), which is expected to invest primarily in commodity and financial
futures and option contracts, as well as fixed income securities and other
investments intended to serve as margin or collateral for the Subsidiary's
derivatives positions. The Fund wholly owns and controls the Subsidiary, and the
Fund and Subsidiary are both managed by the Advisor and the Manager.

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

The Fund does not consolidate the assets, liabilities, capital or operations of
the Subsidiary into its financial statements. Rather, the Subsidiary is
separately presented as an investment in the Fund's Statement of Investments.
Gains or losses on withdrawals of capital from the Subsidiary by the Fund are
recognized on a cost recovery basis. Unrealized appreciation or depreciation on
the Fund's investment in the Subsidiary is recorded in the Fund's Statement of
Assets and Liabilities and the Fund's Statement of Operations. Distributions
received from the Subsidiary are recorded as income on the ex-dividend date.

      For tax purposes, the Subsidiary is an exempted Cayman investment company.
The Subsidiary has received an undertaking from the Government of the Cayman
Islands exempting it from all local income, profits and capital gains taxes
through May of 2036. No such taxes are levied in the Cayman Islands at the
present time. For U.S. income tax purposes, the Subsidiary is a Controlled
Foreign Corporation and as such is not subject to U.S. income tax. However, as a
wholly-owned Controlled Foreign Corporation, the Subsidiary's net income and
capital gain, to the extent of its earnings and profits, will be included each
year in the Fund's investment company taxable income. For the six months ended
June 30, 2007, the Subsidiary has a deficit of $48,648,995 in its taxable
earnings and profits. In addition, any in-kind capital contributions made by the
Fund to the Subsidiary will result in the Fund recognizing taxable gain to the
extent of unrealized gain, if any, on securities transferred to the Subsidiary
while any unrealized losses on securities so transferred will not be recognized
at the time of transfer.

- --------------------------------------------------------------------------------
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 may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Trustees. Securities listed or traded on National
Stock Exchanges or other domestic 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(R) are valued based on the
closing price provided by NASDAQ prior to the time when the Fund's assets are
valued. In the absence of a sale, the security is valued at the last sale price
on the prior trading day, if it is within the spread of the closing "bid" and
"asked" prices, and if not, at the closing bid price. Securities 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
will be valued at the mean between the "bid" and "asked" prices. Futures
contracts traded on a commodities or futures exchange will be valued at the
final settlement price or official closing price on the principal exchange as
reported by such principal


              38 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



exchange at its trading session ending at, or most recently prior to, the time
when the Fund's assets are valued. Options are valued daily based upon the last
sale price on the principal exchange on which the option is traded. 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 Advisor 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. Investments in open-end registered
investment companies (including affiliated funds) are valued at that fund's net
asset value. Short-term "money market type" debt securities with remaining
maturities of sixty days or less are valued at amortized cost (which
approximates market value).

- --------------------------------------------------------------------------------
STRUCTURED SECURITIES. The Fund invests in structured securities whose market
values, interest rates and/or redemption prices are linked to the performance of
underlying foreign currencies, interest rate spreads, stock market indices,
prices of individual securities, commodities or other financial instruments or
the occurrence of other specific events. The structured securities are often
leveraged, increasing the volatility of each note's market value relative to the
change in the underlying linked financial element or event. Fluctuations in
value of these securities are recorded as unrealized gains and losses in the
accompanying Statement of Operations. The Fund records a realized gain or loss
when a structured security is sold or matures.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis or
forward commitment take place generally at least ten days or more after the
trade date. Normally the settlement date occurs within six months after the
trade date; however, the Fund may, from time to time, purchase securities whose
settlement date extends six months or more beyond trade date. During this
period, such securities do not earn interest, are subject to market fluctuation
and may increase or decrease in value prior to their delivery. The Fund
maintains internally designated assets with a market value equal to or greater
than the amount of its purchase commitments. The purchase of securities on a
when-issued basis or forward commitment may increase the volatility of the
Fund's net asset value to the extent the Fund executes such transactions while
remaining substantially fully invested. The Fund may also sell securities that
it purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase. As of June 30, 2007, the Fund had purchased $71,304,673
of securities issued on a when-issued basis or forward commitment and sold
$1,247,852 of securities issued on a when-issued basis or forward commitment.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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") which seeks current income and
stability of principal. 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 Advisor is also the investment advisor 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 Advisor 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.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Advisor, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

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

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


              40 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



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 June 30, 2007, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $338,404,424 expiring by
2015. 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 June
30, 2007, it is estimated that the Fund will not utilize any capital loss
carryforward to offset realized capital gains. During the fiscal year ended
December 31, 2006, the Fund did not utilize any capital loss carryforward to
offset capital gains realized in that fiscal year.

As of December 31, 2006, the Fund had available for federal income tax purposes
post-October losses of $13,947,642 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,
are recorded on the ex-dividend date. Income and capital gain distributions, if
any, are declared and paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

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, to the extent they are not
offset by positive cash balances maintained by the Fund, 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.

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

Class C shares and 0.25 % on Class N shares. The Distributor also receives a
service fee of 0.25% per year under each plan. If either the Class B, Class C or
Class N plan is terminated by the Fund or by the shareholders of a class, the
Board of Trustees and its independent trustees must determine whether the
Distributor shall be entitled to payment from the Fund of all or a portion of
the service fee and/or asset-based sales charge in respect to shares sold prior
to the effective date of such termination. The Distributor determines its
uncompensated expenses under the plan at calendar quarter ends. The

equal to the indirect management fees incurred through the Fund's investment in
IMMF. During the six months ended June 30, 2007, the Advisor waived $38,191 for
IMMF management fees.

- --------------------------------------------------------------------------------
5. FUTURES CONTRACTS

A futures contract is a commitment to buy or sell a specific amount of a
commodity or financial instrument at a negotiated price on a stipulated future
date. Futures contracts are traded on a commodity exchange. The Fund may buy and
sell futures contracts that relate to broadly based securities indices
(financial futures), debt securities (interest rate futures) and various
commodities (commodity futures). The Fund may also buy or write put or call
options on these futures contracts.

      The Fund generally sells futures contracts to hedge against increases in
interest rates and the resulting negative effect on the value of fixed rate
portfolio securities, decreases in market value of portfolio securities, or
decreases in commodity prices. The Fund may also purchase futures contracts
without owning the underlying fixed-income security as an efficient or cost
effective means to gain exposure to changes in interest rates, commodity prices
or market indices.

      Upon entering into a futures contract, the Fund is required to deposit
either cash or securities (initial margin) in an amount equal to a certain
percentage of the contract value. Subsequent payments (variation margin) are
made or received by the Fund each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses. The Fund recognizes a realized gain or loss when the contract is
closed or expires.

      Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. The Statement of Assets and Liabilities reflects a receivable or
payable for the daily mark to market for variation margin. Realized gains and
losses are reported in the Statement of Operations as the closing and expiration
of futures contracts.

      Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

As of June 30, 2007, the Fund had outstanding futures contracts as follows:

- --------------------------------------------------------------------------------
6. TOTAL RETURN SWAP CONTRACTS

A total return swap is an agreement under which a set of future cash flows is
exchanged between two counterparties. One cash flow stream will typically be
based on a reference interest rate or index and the other on the total return of
a reference asset such as a security, a basket of securities, or an index. The
total return includes appreciation or depreciation on the reference asset, plus
any interest or dividend payments. Payments under the swap are based on an
agreed upon principal amount but since this principal amount is not exchanged,
it represents neither an asset nor a liability to either counter-party, and is
referred to as notional. Total return swaps are marked to market daily using
primarily quotations from counterparties and brokers. 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 amount 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. The primary risks associated with total return swaps are credit
risks (if the counterparty fails to meet its obligations) and market risk (if
there is no liquid market for the agreement or unfavorable changes occur in the
reference asset).

As of June 30, 2007, the Fund had entered into the following total return swap
agreements:

7. ILLIQUID SECURITIES

As of June 30, 2007, 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. The
Fund will not invest more than 10% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. Securities that are
illiquid are marked with the applicable footnote on the Statement of
Investments.

- --------------------------------------------------------------------------------
8. SECURITIES LENDING

The Fund lends portfolio securities from time to time in order to earn
additional income. In return, the Fund receives collateral in the form of
securities, letters of credit or cash, against the loaned securities and
maintains collateral in an amount not less than 100% of the market value of the
loaned securities during the period of the loan. The market value of the loaned
securities is determined at the close of business each day. If the Fund is
undercollateralized at the close of business due to an increase in market value
of securities on loan, additional collateral is requested from the borrowing
counterparty and is delivered to the Fund on the next business day. Cash
collateral may be invested in approved investments and the Fund bears the risk
of any loss in value of these investments. The Fund retains a portion of the
interest earned from the collateral. If the borrower defaults on its obligation
to return the securities loaned because of insolvency or other reasons, the Fund
could experience delays and cost in recovering the securities loaned or in
gaining access to the collateral. The Fund continues to receive the economic
benefit of interest or dividends paid on the securities loaned in the form of a
substitute payment received from the borrower. As of June 30, 2007, the Fund had
on loan securities valued at $32,368,114, which are included in the Statement of
Assets and Liabilities as "Investments, at value" and, when applicable, as
"Receivable for Investments sold." Collateral of $32,982,730 was received for
the loans, $26,520,560 of which was received in cash and subsequently invested
in approved investments. In addition, collateral of $6,462,170 was also received
in the form of securities.

9. RECENT ACCOUNTING PRONOUNCEMENT

In September 2006, Financial Accounting Standards Board 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 June 30, 2007, the Advisor 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.

FOOTNOTES TO STATEMENT OF INVESTMENTS

1. Represents the current interest rate for a variable or increasing rate
security.

2. Illiquid security. The aggregate value of illiquid securities as of June 30,
2007 was $50,366, which represents 0.02% of the Fund's net assets. See Note 6 of
accompanying Notes.

3. Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows. These securities amount to $3,882,086 or 1.20% of the Fund's net assets
as of June 30, 2007.

4. When-issued security or forward commitment to be delivered and settled after
June 30, 2007. See Note 1 of accompanying Notes.

5. All or a portion of the security is held in collateralized accounts to cover
initial margin requirements on open futures contracts. The aggregate market
value of such securities is $50,576,280. See Note 4 of accompanying Notes.

6. A sufficient amount of liquid assets has been designated to cover outstanding
written put options, as follows:

RAF FUND LTD. (THE "SUBSIDIARY")
NOTES TO FINANCIAL STATEMENTS  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

RAF Fund Ltd. (the "Fund") is organized as a Cayman Islands Company Limited by
Shares. The Fund intends to carry on the business of an investment company and
to acquire, invest in and hold by way of investment, sell and deal in
commodities and interests therein including futures contracts, options and
forward contracts, shares, stocks, call options, put options, debenture stock,
bonds, obligations, certificates of deposit, bills of exchange and securities of
all kinds. The Fund's investment manager is OppenheimerFunds, Inc. ("OFI" or
"Investment Manager"). The Sub-Advisor is Oppenheimer Real Asset Management,
Inc. ("ORAMI" or the "Subadvisor"), a wholly-owned subsidiary of the Investment
Manager. As of June 30, 2007, 100% of the Fund was owned by Oppenheimer
Commodity Strategy Total Return Fund ("OCSTRF"). OFI is also the investment
advisor of OCSTRF and ORAMI is also the Subadvisor of OCSTRF.

      The beneficial interest of each investor in the Fund is represented by
units of participating shares. The Fund's directors may further designate
classes of participating shares and series within each class. As of June 30,
2007, the directors have not designated classes or series of outstanding
participating shares. During the six months ended, all income, profits, losses
and expenses, if any, of the Fund were allocated pro rata to all participating
shares of the Fund. Issuance of additional participating shares is at the
discretion of the Fund's directors.

      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 may be
valued primarily using dealer-supplied valuations or a portfolio pricing service
authorized by the Board of Directors. Securities listed or traded on National
Stock Exchanges or other domestic 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(R) are valued based on the
closing price provided by NASDAQ prior to the time when the Fund's assets are
valued. In the absence of a sale, the security is valued at the last sale price
on the prior trading day, if it is within the spread of the closing "bid" and
"asked" prices, and if not, at the closing bid price. Securities 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
will be valued at the mean between the "bid" and "asked" prices. Futures
contracts traded on a commodities or futures exchange will be valued at the
final settlement price or official closing price on the principal exchange as
reported by such principal exchange at its trading session ending at, or most
recently prior to, the time when the Fund's assets are

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

valued. Options are valued daily based upon the last sale price on the principal
exchange on which the option is traded. 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
Directors. Investments in open-end registered investment companies (including
affiliated funds) are valued at that fund's net asset value. Short-term "money
market type" debt securities with remaining maturities of sixty days or less are
valued at amortized cost (which approximates market value).

- --------------------------------------------------------------------------------
STRUCTURED NOTES. The Fund invests in structured notes whose market values,
interest rates and/or redemption prices are linked to the performance of
underlying foreign currencies, interest rate spreads, stock market indices,
prices of individual securities, commodities or other financial instruments or
the occurrence of other specific events. The structured notes are often
leveraged, increasing the volatility of each note's market value relative to the
change in the underlying linked financial element or event. Fluctuations in
value of these securities are recorded as unrealized gains and losses in the
accompanying Statement of Operations. The Fund records a realized gain or loss
when a structured note is sold or matures.

- --------------------------------------------------------------------------------
SECURITIES ON A WHEN-ISSUED BASIS OR FORWARD COMMITMENT. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis or
forward commitment take place generally at least ten days or more after the
trade date. Normally the settlement date occurs within six months after the
trade date; however, the Fund may, from time to time, purchase securities whose
settlement date extends six months or more beyond trade date. During this
period, such securities do not earn interest, are subject to market fluctuation
and may increase or decrease in value prior to their delivery. The Fund
maintains internally designated assets with a market value equal to or greater
than the amount of its purchase commitments. The purchase of securities on a
when-issued basis or forward commitment may increase the volatility of the
Fund's net asset value to the extent the Fund executes such transactions while
remaining substantially fully invested. The Fund may also sell securities that
it purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase. As of June 30, 2007, the Fund had purchased $45,012,465
of securities issued on a when-issued basis or forward commitment and sold
$12,775,686 of securities issued on a when-issued basis or forward commitment.

- --------------------------------------------------------------------------------
CONCENTRATION OF RISKS. The Fund from time to time may have elements of
concentration risk due to the value of certain securities held compared to the
overall net investments value of the Fund. Such concentrations may subject the
Fund to additional risks.


              64 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

- --------------------------------------------------------------------------------
INVESTMENTS WITH OFF-BALANCE SHEET MARKET RISK. The Fund enters into financial
instrument transactions 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.

- --------------------------------------------------------------------------------
INCOME TAXES. The Fund has received an undertaking from the Government of the
Cayman Islands exempting it from all local income, profits and capital gains
taxes through May of 2036. No such taxes are levied in the Cayman Islands at the
present time. The Fund is a Controlled Foreign Corporation under U.S. tax laws
and as such is not subject to U.S. income tax. Therefore, the Fund is not
required to record a tax provision.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, if any, are declared and paid annually from the Fund's tax basis
earnings and profits. Distributions are recorded on ex-dividend date.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
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, to the extent they are not
offset by positive cash balances maintained by the Fund, 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.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

INDEMNIFICATIONS. The Fund's organizational documents provide current and former
directors 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 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. CAPITAL TRANSACTIONS

The Fund has authorized 5,000,000 participating shares of $.01 par value per
share. The Fund issued 4,000,000 participating shares for $500,000 on August 15,
2006 in conjunction with OCSTRF's initial capitalization of the Fund. All
subsequent capital contributions and withdrawals did not have participating
shares associated with the transaction.

Capital transactions were as follows:

              66 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



- --------------------------------------------------------------------------------
SUB-ADVISOR FEES. The Investment Manager retains the Sub-Advisor to provide the
day-to-day portfolio management of the Fund. Under the Sub-Advisory Agreement,
the Investment Manager pays the Sub-Advisor an annual fee in monthly
installments, based on the average daily net assets of the Fund at an average
annual rate as shown in the following table:

                       FEE SCHEDULE
                       ------------------------------
                       Up to $200 million      0.500%
                       Next $200 million       0.450
                       Next $200 million       0.425
                       Next $200 million       0.400
                       Over $800 million       0.375

- --------------------------------------------------------------------------------
4. FUTURES CONTRACTS

A futures contract is a commitment to buy or sell a specific amount of a
commodity or financial instrument at a negotiated price on a stipulated future
date. Futures contracts are traded on a commodity exchange. The Fund may buy and
sell futures contracts that relate to broadly based securities indices
(financial futures), debt securities (interest rate futures) and various
commodities (commodities futures) in order to gain exposure to or protection
from changes in market value of stock and bonds or interest rates. The Fund may
also buy or write put or call options on these futures contracts.

      The Fund generally sells futures contracts to hedge against increases in
interest rates and the resulting negative effect on the value of fixed rate
portfolio securities, decreases in market value of portfolio securities, or
decreases in commodity prices. The Fund may also purchase futures contracts
without owning the underlying fixed-income security as an efficient or cost
effective means to gain exposure to changes in interest rates, commodity prices
or market indices.

      Upon entering into a futures contract, the Fund is required to deposit
either cash or securities (initial margin) in an amount equal to a certain
percentage of the contract value. Subsequent payments (variation margin) are
made or received by the Fund each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses. The Fund recognizes a realized gain or loss when the contract is
closed or has expired.

      Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. The Statement of Assets and Liabilities reflect a receivable and/or
payable for the daily mark to market for variation margin. Realized gains and
losses are reported in the Statements of Operations and Changes in Net Assets as
closing and expiration of futures contracts. The net change in unrealized
appreciation and depreciation is reported in the Statements of Operations and
Changes in Net Assets.

      Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

5. OPTION ACTIVITY

The Fund may buy and sell put and call options, or write put and covered call
options on portfolio securities in order to produce incremental earnings or
protect against changes in the value of portfolio securities.

      The Fund generally purchases put options or writes covered call options to
hedge against adverse movements in the value of portfolio holdings. When an
option is written, the Fund receives a premium and becomes obligated to sell or
purchase the underlying security at a fixed price, upon exercise of the option.

      Options are valued daily based upon the last sale price on the principal
exchange on which the option is traded and unrealized appreciation or
depreciation is recorded. The Fund will realize a gain or loss upon the
expiration or closing of the option transaction. When an option is exercised,
the proceeds on sales for a written call option, the purchase cost for a written
put option, or the cost of the security for a purchased put or call option is
adjusted by the amount of premium received or paid.

      Securities designated to cover outstanding call options are noted in the
Statement of Investments where applicable. Contracts subject to call, expiration
date, exercise price, premium received and market value are detailed in a note
to the Statement of Investments. Options written are reported as a liability in
the Statement of Assets and Liabilities. Realized gains and losses are reported
in the Statement of Operations and Changes in Net Assets.

      The risk in writing a call option is that the Fund gives up the
opportunity for profit if the market price of the security or commodity
increases and the option is exercised. The


              68 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



risk in writing a put option is that the Fund may incur a loss if the market
price of the security or commodity decreases and the option is exercised. The
risk in buying an option is that the Fund pays a premium whether or not the
option is exercised. The Fund also has the additional risk of not being able to
enter into a closing transaction if a liquid secondary market does not exist.

Written option activity for the six months ended June 30, 2007 was as follows:

                                         CALL OPTIONS               PUT OPTIONS

6. ILLIQUID SECURITIES

As of June 30, 2007, investments in securities included issues that are

Securities that are illiquid are marked with the applicable footnote on the
Statement of Investments.

8. RECENT ACCOUNTING PRONOUNCEMENT

In September 2006, Financial Accounting Standards Board 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 June 30, 2007, 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.

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

                                       2


     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 06/30/2007, 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.
