Portfolio holdings and allocations are subject to change. Percentages are as of
June 30, 2008, 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.

      shares are offered only to certain institutional investors under a special
      agreement with the Distributor, and to present or former officers,
      directors, trustees or employees (and their eligible family members) of
      the Fund, the Manager, its affiliates, its parent company and the
      subsidiaries of its parent company, and retirement plans established for
      the benefit of such individuals.

      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 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 June
      30, 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 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 exceptions

FUND EXPENSES Continued

      described in the Statement of Additional Information). Therefore, the
      "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 182/366
(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, 2008 are as follows:



CLASS             EXPENSE RATIOS
- ----------------------------------

- ----------------------------------
Class N               1.44
- ----------------------------------
Class Y               0.59


The expense ratios reflect reduction to custodian expenses and voluntary waivers
or reimbursements of expenses by the Fund's Manager 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 and reduction
to custodian expenses, if applicable.

initial margin requirements on open futures contracts. The aggregate market
value of such securities is $35,500,438. See Note 5 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 $5,963,512 or 0.27% of the Fund's net assets
as of June 30, 2008.

6. When-issued security or delayed delivery to be delivered and settled after
June 30, 2008. See Note 1 of accompanying Notes.

assets as of June 30, 2008.

VALUATION INPUTS
- --------------------------------------------------------------------------------

Various data inputs are used in determining the value of each of the Fund's
investments as of the reporting period end. These data inputs are categorized in
the following hierarchy under applicable financial accounting standards:

      1) Level 1 - quoted prices in active markets for identical assets or
      liabilities (including securities actively traded on a securities
      exchange)
      2) Level 2 - inputs other than quoted prices that are observable for the
      asset (such as quoted prices for similar assets and market-corroborated
      inputs such as interest rates, prepayment speeds, credit risks, etc.)
      3) Level 3 - unobservable inputs (including the Manager's own judgments
      about assumptions that market participants would use in pricing the
      asset).

The market value of the Fund's investments was determined based on the following
inputs as of June 30, 2008:

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Commodity Strategy Total Return Fund (the "Fund"), is registered
under the Investment Company Act of 1940, as amended, as an open-end management
investment company. The Fund's investment objective is to seek total return.
Total return refers to the change in value of an investment in shares of the
Fund over time resulting from changes in the value of the Fund's investments and
income on those investments. The Fund's investment adviser is OppenheimerFunds,
Inc. (the "Adviser"). The Sub-Adviser is Oppenheimer Real Asset Management, Inc.
(the "Manager"), a wholly-owned subsidiary of the Adviser.

      The Fund offers Class A, Class B, Class C, Class N and Class Y shares.
Class A shares are sold at their offering price, which is normally net asset
value plus a front-end sales charge. Class B, Class C and Class N shares are
sold without a front-end sales charge but may be subject to a contingent
deferred sales charge ("CDSC"). Class N shares are sold only through retirement
plans. Retirement plans that offer Class N shares may impose charges on those
accounts. Class Y shares are sold to certain institutional investors without
either a front-end sales charge or a CDSC, 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 72
months 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 Adviser and the Manager.

      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, 2008, the Subsidiary has a surplus of $306,149,190 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 trading.

      Effective for fiscal periods beginning after November 15, 2007, FASB
Statement of Financial Accounting Standards No. 157, FAIR VALUE MEASUREMENTS,
establishes a hierarchy for measuring fair value of assets and liabilities. As
required by the standard, each investment asset or liability of the Fund is
assigned a level at measurement date based on the significance and source of the
inputs to its valuation. Quoted prices in active markets for identical
securities are classified as "Level 1", inputs other than quoted prices for an
asset that are observable are classified as "Level 2" and unobservable inputs,
including the Manager's judgment about the assumptions that a market participant
would use in pricing an asset or liability are classified as "Level 3". The
inputs used for valuing securities are not necessarily an indication of the
risks associated with investing in those securities. A table summarizing the
Fund's investments under these levels of classification is included following
the Statement of Investments.

      Securities are valued using quoted market prices, when available, as
supplied primarily either by portfolio pricing services approved by the Board of
Trustees or dealers. These securities are typically classified within Level 1 or
2; however, they may be designated as Level 3 if the dealer or portfolio pricing
service values a security through an internal model with significant
unobservable market data inputs.

      Securities traded on a registered U.S. securities exchange are valued
based on the last sale price of the security reported on the principal exchange
on which traded, prior to the time when the Fund's assets are valued. Securities
whose principal exchange is NASDAQ(R) are valued based on the official closing
prices reported by NASDAQ prior to the time

             F28 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



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 current day's closing "bid" and "asked" prices, and if not, at the
current day's closing bid price. A foreign security traded on a foreign exchange
is valued based on the last sale price on the principal exchange on which the
security is traded, as identified by the portfolio pricing service used by the
Manager, prior to the time when the Fund's assets are valued. In the absence of
a sale, the security is valued at the most recent official closing price on the
principal exchange on which it is traded.

      Shares of a registered investment company that are not traded on an
exchange are valued at that investment company's net asset value per share.

      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 are valued
at the mean between the "bid" and "asked" prices.

      "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. These
securities are typically designated as Level 2.

      In the absence of a readily available quoted market price, including for
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 the securities' respective exchanges, the Manager, acting
through its internal valuation committee, in good faith determines the fair
valuation of that asset using consistently applied procedures under the
supervision of the Board of Trustees (which reviews those fair valuations by the
Manager). Those procedures include certain standardized methodologies to fair
value securities. Such methodologies include, but are not limited to, pricing
securities initially at cost and subsequently adjusting the value based on:
changes in company specific fundamentals, changes in an appropriate securities
index, or changes in the value of similar securities which may be adjusted for
any discounts related to resale restrictions. When possible, such methodologies
use observable market inputs such as quoted prices of similar securities,
observable interest rates, currency rates and yield curves. The methodologies
used for valuing securities are not necessarily an indication of the risks
associated with investing in those securities.

      Fair valued securities may be classified as "Level 3" if the valuation
primarily reflects the Manager's own assumptions about the inputs that market
participants would use in valuing such securities.

      There have been no significant changes to the fair valuation methodologies
during the period.

      The net asset value per share of the Subsidiary is determined as of the
close of the Exchange, on each day the Exchange is open for trading. The net
asset value per share is determined by dividing the value of the Subsidiary's
net assets by the number of shares that are outstanding. The Subsidiary values
its investments in the same manner as the Fund as described above.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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 OR DELAYED DELIVERY BASIS. The Fund may purchase
securities on a "when-issued" basis, and may purchase or sell securities on a
"delayed delivery" basis. "When-issued" or "delayed delivery" refers to
securities whose terms and indenture are available and for which a market
exists, but which are not available for immediate delivery. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis
normally takes place within six months and possibly as long as two years or more
after the 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 purchase of securities on a when-issued basis may increase
the volatility of the Fund's net asset value to the extent the Fund executes
such transactions while remaining substantially fully invested. When the Fund
engages in when-issued or delayed delivery transactions, it relies on the buyer
or seller, as the case may be, to complete the transaction. Their failure to do
so may cause the Fund to lose the opportunity to obtain or dispose of the
security at a price and yield it considers advantageous. The Fund maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. The Fund may also sell securities that it
purchased on a when-issued basis or forward commitment prior to settlement of
the original purchase.

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

             F30 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



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.

- --------------------------------------------------------------------------------
INVESTMENTS WITH OFF-BALANCE SHEET MARKET 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. 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.

During the fiscal year ended December 31, 2007, the Fund did not utilize any
capital loss carryforward to offset capital gains realized in that fiscal year.
As of December 31, 2007, the Fund had available for federal income tax purposes
post-October losses of $19,477,840 and unused capital loss carryforwards as
follows:

                                =============
                     

As of June 30, 2008, the Fund had available for federal income tax purposes an
estimated capital loss carryforward of $47,482,720 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 June 30, 2008, it is estimated that the Fund will utilize
$329,764,288 of capital loss carryforward to offset realized capital gains.

      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.

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of June 30, 2008 are noted in the following

deferral of losses or tax realization of financial statement unrealized gain or

- --------------------------------------------------------------------------------
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 and capital gain distributions, if any, are
declared and paid annually or at other times as deemed necessary by the Manager.

- --------------------------------------------------------------------------------
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. Discount and
premium, which are included in interest income on the Statement of Operations,
are amortized or accreted daily.

             F32 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



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

year cannot be recovered in subsequent periods. Fees incurred by the Fund under

DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans (the "Plans") for Class B, Class C
and Class N 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 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

WAIVERS AND REIMBURSEMENTS OF EXPENSES. The Subsidiary has entered into a
separate contract with the Adviser for the management of the Subsidiary's
portfolio. The Adviser has contractually agreed to waive the management fee it
receives from the Fund in an amount equal to the management fee paid to the
Adviser by the Subsidiary. This undertaking will continue in effect for so long
as the Fund invests in the Subsidiary, and may not be terminated by the Adviser
unless the Adviser first obtains the prior approval of the Fund's Board of
Trustees for such termination. During the six months ended June 30, 2008, the
Adviser waived $2,146,629.

undertaking may be amended or withdrawn at any time.

      The Adviser 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 June 30, 2008, the Adviser waived $36,115 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. 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 index futures). The Fund may also buy or
write put or call options on these futures contracts.

      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 valued.

      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.

      Futures contracts are reported on a schedule following the Statement of
Investments. Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. Cash held by the broker to cover initial margin requirements on
open futures contracts and the receivable and/or payable for the daily mark to
market for variation margin are noted in the Statement of Assets and
Liabilities. The net change in unrealized appreciation (depreciation) is
reported in the Statement of Operations. Realized gains (losses) are reported in
the Statement of Operations at the closing or expiration of futures contracts.

      Risks of entering into futures contracts (and related options) include the
possibility that the Fund may be unable to enter into a closing transaction or
an offsetting position due to an illiquid market and, if used for hedging
purposes, the risk that the price of the contract will correlate imperfectly
with the prices of the Fund's securities.

- --------------------------------------------------------------------------------
6. 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.

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

- --------------------------------------------------------------------------------
6. SWAP CONTRACTS Continued

      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, or the cost of
selling protection (paying the notional amount) when a credit event occurs,
pricing transparency when assessing the cost of a credit default swap, and the
need to fund the delivery obligation (either cash or defaulted securities).

- --------------------------------------------------------------------------------
TOTAL RETURN SWAP CONTRACTS. A total return swap is an agreement between
counterparties to exchange a set of future cash flows on the notional amount of
the contract. One cash flow is typically 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.

- --------------------------------------------------------------------------------
8. ILLIQUID SECURITIES

As of June 30, 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. 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 an applicable footnote
on the Statement of Investments.

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

In March 2008, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 161, "Disclosures about
Derivative Instruments and Hedging Activities." This standard requires enhanced
disclosures about derivative and hedging activities, including qualitative
disclosures about how and why the Fund uses derivative instruments, how these
activities are accounted for, and their effect on the Fund's financial position,
financial performance and cash flows. SFAS No. 161 is effective for financial
statements issued for fiscal years beginning after November 15, 2008 and interim
periods within those fiscal years. At this time, management is evaluating the
implications of SFAS No. 161 and its impact on the Fund's financial statements
and related disclosures.

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,
2008 was $1,086,454, which represents 0.20% of the Fund's net assets. See Note 7
of accompanying Notes.

3. 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 $117,969,785. See Note 4 of accompanying Notes.

4. 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 $3,766,457 or 0.69% of the Fund's net assets
as of June 30, 2008.

5. When-issued security or delayed delivery to be delivered and settled after
June 30, 2008. See Note 1 of accompanying Notes.

6. A sufficient amount of liquid assets has been designated to cover outstanding
written call options.

7. Represents securities sold under Rule 144A, which are exempt from
registration under the Securities Act of 1933, as amended. These securities have
been determined to be liquid under guidelines established by the Board of
Directors. These securities amount to $18,313,254 or 3.37% of the Fund's net
assets as of June 30, 2008.

8. This bond has no contractual maturity date, is not redeemable and
contractually pays an indefinite stream of interest. Rate reported represents
the current interest rate for this variable rate security.

9. Non-income producing security.

VALUATION INPUTS
- --------------------------------------------------------------------------------

Various data inputs are used in determining the value of each of the Fund's
investments as of the reporting period end. These data inputs are categorized in
the following hierarchy under applicable financial accounting standards:

      1) Level 1--quoted prices in active markets for identical assets or
      liabilities (including securities actively traded on a securities
      exchange)
      2) Level 2--inputs other than quoted prices that are observable for the
      asset (such as quoted prices for similar assets and market-corroborated
      inputs such as interest rates, prepayment speeds, credit risks, etc.)
      3) Level 3--unobservable inputs (including the Manager's own judgments
      about assumptions that market participants would use in pricing the
      asset).

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-Adviser is Oppenheimer Real Asset Management,
Inc. ("ORAMI" or the "Subadviser"), a wholly-owned subsidiary of the Investment
Manager. As of June 30, 2008, 100% of the Fund was owned by Oppenheimer
Commodity Strategy Total Return Fund ("OCSTRF"). OFI is also the investment
adviser of OCSTRF and ORAMI is also the Subadviser 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,
2008, 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 trading.

      Effective for fiscal periods beginning after November 15, 2007, FASB
Statement of Financial Accounting Standards No. 157, FAIR VALUE MEASUREMENTS,
establishes a hierarchy for measuring fair value of assets and liabilities. As
required by the standard, each investment asset or liability of the Fund is
assigned a level at measurement date based on the significance and source of the
inputs to its valuation. Quoted prices in active markets for identical
securities are classified as "Level 1", inputs other than quoted prices for an
asset that are observable are classified as "Level 2" and unobservable inputs,
including the Manager's judgment about the assumptions that a market participant
would use in pricing an asset or liability are classified as "Level 3". The
inputs used for valuing securities are not necessarily an indication of the
risks associated with investing in those securities. A table summarizing the
Fund's investments under these levels of classification is included following
the Statement of Investments.

      Securities are valued using quoted market prices, when available, as
supplied primarily either by portfolio pricing services approved by the Board of
Directors or dealers. These securities are typically classified within Level 1
or 2; however, they may be designated as Level 3 if the dealer or portfolio
pricing service values a security through an internal model with significant
unobservable market data inputs.

             32 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



      Securities traded on a registered U.S. securities exchange are valued
based on the last sale price of the security reported on the principal exchange
on which traded, prior to the time when the Fund's assets are valued. Securities
whose principal exchange is NASDAQ(R) are valued based on the official closing
prices 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 current day's closing "bid"
and "asked" prices, and if not, at the current day's closing bid price. A
foreign security traded on a foreign exchange is valued based on the last sale
price on the principal exchange on which the security is traded, as identified
by the portfolio pricing service used by the Manager, prior to the time when the
Fund's assets are valued. In the absence of a sale, the security is valued at
the most recent official closing price on the principal exchange on which it is
traded.

      Shares of a registered investment company that are not traded on an
exchange are valued at that investment company's net asset value per share.

      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 are valued
at the mean between the "bid" and "asked" prices.

      "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. These
securities are typically designated as Level 2.

      In the absence of a readily available quoted market price, including for
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 the securities' respective exchanges, the Manager, acting
through its internal valuation committee, in good faith determines the fair
valuation of that asset using consistently applied procedures under the
supervision of the Board of Directors (which reviews those fair valuations by
the Manager). Those procedures include certain standardized methodologies to
fair value securities. Such methodologies include, but are not limited to,
pricing securities initially at cost and subsequently adjusting the value based
on: changes in company specific fundamentals, changes in an appropriate
securities index, or changes in the value of similar securities which may be
adjusted for any discounts related to resale restrictions. When possible, such
methodologies use observable market inputs such as quoted prices of similar
securities, observable interest rates, currency rates and yield curves. The
methodologies used for valuing securities are not necessarily an indication of
the risks associated with investing in those securities.

      Fair valued securities may be classified as "Level 3" if the valuation
primarily reflects the Manager's own assumptions about the inputs that market
participants would use in valuing such securities.

      There have been no significant changes to the fair valuation methodologies
during the period.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

SECURITIES ON A WHEN-ISSUED OR DELAYED DELIVERY BASIS. The Fund may purchase
securities on a "when-issued" basis, and may purchase or sell securities on a
"delayed delivery" basis. "When-issued" or "delayed delivery" refers to
securities whose terms and indenture are available and for which a market
exists, but which are not available for immediate delivery. Delivery and payment
for securities that have been purchased by the Fund on a when-issued basis
normally takes place within six months and possibly as long as two years or more
after the 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 purchase of securities on a when-issued basis may increase
the volatility of the Fund's net asset value to the extent the Fund executes
such transactions while remaining substantially fully invested. When the Fund
engages in when-issued or delayed delivery transactions, it relies on the buyer
or seller, as the case may be, to complete the transaction. Their failure to do
so may cause the Fund to lose the opportunity to obtain or dispose of the
security at a price and yield it considers advantageous. The Fund maintains
internally designated assets with a market value equal to or greater than the
amount of its purchase commitments. 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, 2008, the Fund had purchased securities issued on a when-issued
or delayed delivery basis and sold securities issued on a delayed delivery basis
as follows:

                  
                  
                                                 WHEN-ISSUED OR
                                               DELAYED DELIVERY
                                             BASIS TRANSACTIONS
                  -----------------------------------------------
                                          
                  Purchased securities             $  7,731,838
                  Sold securities                       614,047
                  

- --------------------------------------------------------------------------------
FOREIGN CURRENCY TRANSLATION. The Fund's accounting records are maintained in
U.S. dollars. The values of securities denominated in foreign currencies and
amounts related to the purchase and sale of foreign securities and foreign
investment income are translated into U.S. dollars as of the close of the
Exchange, normally 4:00 P.M. Eastern time, on each day the Exchange is open for
trading. Foreign exchange rates may be valued primarily using a reliable bank,
dealer or service authorized by the Board of Directors.

      Reported net realized gains and losses from foreign currency transactions
arise from sales of portfolio securities, sales and maturities of short-term
securities, sales of foreign currencies, exchange rate fluctuations between the
trade and settlement dates on securities transactions, and the difference
between the amounts of dividends, interest, and foreign withholding taxes
recorded on the Fund's books and the U.S. dollar equivalent of the amounts
actually received or paid. Net unrealized appreciation and depreciation on the
translation of assets and liabilities denominated in foreign currencies arise
from changes in the values of assets and liabilities, including investments in
securities at fiscal period end, resulting from changes in exchange rates.

             34 | OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND



      The effect of changes in foreign currency exchange rates on investments is
separately identified from the fluctuations arising from changes in market
values of securities held and reported with all other foreign currency gains and
losses in the Fund's Statement of Operations.

- --------------------------------------------------------------------------------
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 is recognized on an accrual basis. Discount and
premium, which are included in interest income on the Statement of Operations,
are amortized or accreted daily.

- --------------------------------------------------------------------------------
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
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 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. 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:

          FEE SCHEDULE
          --------------------------------------------

The Fund shall bear all fees and expenses related to the business and affairs of
the Fund, including among others, directors' fees, audit fees, custodian fees
and expenses in connection with the purchase and sale of securities and other
Fund assets.

- --------------------------------------------------------------------------------
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. 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 index futures). The Fund may also buy or
write put or call options on these futures contracts.

      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 valued.

      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.

      Futures contracts are reported on a schedule following the Statement of
Investments. Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. Cash held by the broker to cover initial margin requirements on
open futures contracts and the receivable and/or payable for the daily mark to
market for variation margin are noted in the Statement of Assets and
Liabilities. The net change in unrealized appreciation (depreciation) is
reported in the Statement of Operations. Realized gains (losses) are reported in
the Statement of Operations at the closing or expiration of futures contracts.

      Risks of entering into futures contracts (and related options) include the
possibility that the Fund may be unable to enter into a closing transaction or
an offsetting position due to an illiquid market and, if used for hedging
purposes, the risk that the price of the contract will correlate imperfectly
with the prices of the Fund's securities.

5. OPTION ACTIVITY

The Fund may buy and sell put and call options, or write put and covered call
options. 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. The difference between the premium
received or paid, and market value of the option, is recorded as unrealized
appreciation or depreciation. The net change in unrealized appreciation or
depreciation is reported in the Statement of Operations. When an option is
exercised, the cost of the security purchased or the proceeds of the security
sale are adjusted by the amount of premium received or paid. Upon the expiration
or closing of the option transaction, a gain or loss is reported in the
Statement of Operations.

      Securities designated to cover outstanding call or put options are noted
in the Statement of Investments where applicable. Options written are reported
in a schedule following the Statement of Investments and as a liability in the
Statement of Assets and Liabilities.

      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 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 that there may be an illiquid market where the Fund is
unable to close the contract.

Written option activity for the six months ended June 30, 2008 was as follows:



                                            CALL OPTIONS               PUT OPTIONS

6. ILLIQUID SECURITIES

As of June 30, 2008, 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.
Securities that are illiquid are marked with the applicable footnote on the
Statement of Investments.

8. RECENT ACCOUNTING PRONOUNCEMENT

In March 2008, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 161, "Disclosures about
Derivative Instruments and Hedging Activities." This standard requires enhanced
disclosures about derivative and hedging activities, including qualitative
disclosures about how and why the Fund uses derivative instruments, how these
activities are accounted for, and their effect on the Fund's financial position,
financial performance and cash flows. SFAS No. 161 is effective for financial
statements issued for fiscal years beginning after November 15, 2008 and interim
periods within those fiscal years. At this time, management is evaluating the
implications of SFAS No. 161 and its impact on the Fund's financial statements
and related disclosures.

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:

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

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

      -     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

      -     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 06/30/2008, 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.
