Fund Performance Discussion

The Fund’s Class A shares (without sales charge) returned –1.80% during the period, underperforming the S&P GSCI Index (the “Index”), which returned 0.08%. The negative results of the Fund and muted results of the Index occurred over a volatile period for commodities. The Fund’s performance reflects the effects of the Fund’s business and operating expenses, which are higher relative to the Index, whose performance does not reflect transaction costs, fees, expenses and taxes, and which investors cannot directly purchase.

MARKET OVERVIEW

It was a volatile period for commodities, which were impacted by a number of macroeconomic issues throughout the reporting period. The period began during a time of improved market sentiment in which the United States managed to avoid a return to recession and European policymakers appeared to take steps to address the region’s sovereign debt and banking sector

crises. Renewed investor optimism helped produce gains across commodities and international equity markets over the first three months of 2012. The rebound gained momentum after the European Central Bank the (“ECB”) implemented dual Long-Term Refinancing Operations to enhance liquidity for troubled banks and reduce rates on newly issued sovereign debt securities.

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 3

The second quarter was more volatile as commodity prices weakened in tandem with the global economy, and oil prices in particular saw a steep drop. The fear of contagion from the worsening European sovereign debt crisis and a recession across much of Europe drove negative market sentiment. Growth also slowed across much of the emerging world with notable declines in activity in Brazil, India and China. In the U.S., slow growth and high unemployment weighed on stocks.

Commodities performed positively over the third quarter of 2012, before declining again in the fourth quarter. Several factors combined to lift commodity prices in the third quarter, including a broad-based drop in the U.S. dollar, which typically boosts the performance of commodities. In addition, a global wave of money printing and unconventional monetary policy easing by central banks including the ECB and the Federal Reserve (the “Fed”), benefited commodities in the third quarter. The ECB moved first in early September with its announcement of an open-ended program called Outright Monetary Transactions. The Fed announced the following week that it would embark on open-ended QE3 by purchasing $40 billion of agency mortgage-backed securities monthly until further notice, with a goal of reducing unemployment. It also extended Operation Twist. These measures tend to support hard asset prices (including commodities) as investors look for ways to protect against weakening

fiat currencies and the risk of future inflation. While the dollar remained weak over the last quarter of the period, commodities lost value as a result of uncertainty over the U.S. elections and the fiscal cliff/debt ceiling, and concerns over slowing growth in the emerging markets.

FUND REVIEW

The strongest performing sectors of the Index were agriculture and precious metals, which generated returns of 6.46% and 6.21% for the Index, respectively. Industrial metals also generated a positive return of 1.37%. Energy and livestock produced negative returns of 1.37% and 3.95% for the Index, respectively.

The Fund had its largest weighting to energy, which consisted of roughly 69% of its commodity-linked investments at period end. Energy’s declines were led by natural gas and West Texas Intermediate (“WTI”) crude oil. Unleaded gasoline was the strongest performer for the sector this period, followed by Brent, heating oil and gasoil. Natural gas declined in part because of growing domestic production combined with an unusually mild winter of 2011 and a warm start to the winter of 2012. In addition, natural gas is among the most expensive commodities to store. Regarding Brent and gasoil, tight supply globally combined with geopolitical risk in the Middle East to support prices this year. The strength in unleaded gasoline was partly a function of slack demand in the U.S. being outweighed

by numerous refinery disruptions which reduced supplies and caused domestic inventories to decline. At the same time, increasing global demand and growing exports helped to support prices. Relatively cheap WTI and extremely cheap natural gas (often used as an energy source for refinery distillation) combined in 2012 to make the U.S. a prime low-cost producer and exporter of unleaded gas, especially to Latin America.

Agriculture, with approximately 15.5% of the Fund’s commodity-linked investments at period end, was the second largest allocation for the Fund. Its positive performance was driven primarily by a strong rise in soybeans and corn. Agriculture also benefited from the performance of Kansas Wheat, Chicago Wheat and cocoa. In contrast, cotton and sugar both experienced declines, and coffee was the worst agriculture performer in the Index for the year. Regarding the grains, although the planting season in the U.S. got off to a strong start after a mild winter, severe drought in the grain belt reduced yield estimates sharply for corn, soybeans and wheat, reducing worries of oversupply this year and sending grain prices sharply higher. In fact, corn and soybeans reached all-time high prices over the summer. Wheat was a strong performer later in the year as fears of potential export reductions from Russia and Ukraine helped support prices. Sugar was negatively impacted by increased production from Brazil and India, while cotton faced the challenge of solid U.S. production plus reduced demand from China. Finally, ample

supplies of Arabica coffee from Brazil and reduced demand from recession-plagued Europe contributed to the steep price drop in that commodity.

Precious metals and industrial metals consisted of approximately 4% and 7% of the Fund’s commodity-linked investments at period end, respectively. The precious metals sector benefited from the positive performance of silver and gold. Significantly, this marked the 12th year in a row when gold generated a positive return. Central banks collectively bought more than 400 metric tons of gold in 2012, and investment demand continued to grow throughout the year. Major buyers included South Korea, the Philippines, Mexico, Kazakhstan, Russia, Ukraine, Turkey and Argentina. U.S. dollar weakness also helped precious metals pricing in 2012, as did mining disruptions (principally in South Africa) and production shortfalls. The industrial metals sector performed markedly better than it did in 2011, when it experienced significant declines. Lead and zinc were the strongest performers this period, followed by copper. Aluminum and nickel experienced declines. Expectations of growing metal demand in 2013, notably from China, and early signs of improving growth in emerging markets were key drivers of rising prices. Excess supplies of aluminum pressured that metal. Monetary easing by central banks around the world, fiscal stimulus in China and mining disruptions (principally caused by labor disputes) overcame signs of slowing growth in

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 5

the emerging markets to help support the sector this year.

Livestock, which consisted of roughly 5% of the Fund’s commodity-linked investments at period end, produced a negative return driven by the performance of feeder cattle. Live cattle and lean hogs also experienced declines to a lesser degree. The combined impact of drought and a sharp spike in grain prices caused ranchers in the U.S. to cull their herds, which hurt livestock prices. Supplies were forced onto the market, depressing prices this year, but raising concerns about future supply. High storage costs also contributed to the negative returns.

STRATEGY & OUTLOOK

Looking forward, we are on the lookout for improving global growth expectations, continued weakness in the dollar as the Fed executes open-ended quantitative easing, fewer sovereign debt crisis-related headlines

from Europe and progress toward addressing the debt ceiling. Any of these factors could provide additional support for commodity prices. We expect volatility in the commodity complex to continue in the near term as investors react to shifting macroeconomic headlines and the market adjusts to the latest developments in Europe and the Middle East.

We maintain our expectation that short-term interest rates in the U.S. will remain anchored at extremely low levels for the foreseeable future. Virtually every central bank that can print money is printing money, and those that can’t are pursuing various forms of unconventional monetary policy easing. As long as the Fed’s accommodative policy remains in place, and the global economy continues to grow, we believe that commodities can perform well in 2013 and continue to provide diversification benefits and an inflation hedge for investors.

Fund returns include changes in share price, reinvested distributions, and the applicable sales charge: for Class A shares, the current maximum initial sales charge of 5.75%; for Class B shares, the contingent deferred sales charge of 5% (1-year) and 2% (5-year); and for Class C and N shares, the contingent deferred sales charge of 1% for the 1-year period. There is no sales charge for Class I and Class Y shares. Because Class B shares convert to Class A shares 72 months after purchase, the 10-year return for Class B shares uses Class A performance for the period after conversion. Returns for periods of less than one year are cumulative and not annualized.

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 (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 December 31, 2012.

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), or a $12.00 fee imposed annually on accounts valued at less than $500.00 (subject to exceptions described in the Statement of Additional Information). Therefore, the “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.

Class N		1,000.00		1,017.60		7.64
Class Y		1,000.00		1,021.57		3.61

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated fund, based on the 6-month period ended December 31, 2012 are as follows:

Class	Expense Ratios
Class A		1.30	%
Class B		2.07
Class C		2.12
Class I		0.69
Class N		1.50
Class Y		0.71

The expense ratios reflect voluntary waivers and/or reimbursements of expenses by the Fund’s Manager and Transfer Agent. Some of these undertakings may be modified or terminated at any time, as indicated in the Fund’s prospectus. 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.

NOTES TO FINANCIAL STATEMENTS    

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. The Fund’s investment adviser is OppenheimerFunds, Inc. (the “Manager”). The Sub-Adviser is Oppenheimer Real Asset Management, Inc. (the “Sub-Adviser”), a wholly-owned subsidiary of the Manager.

The Fund offers Class A, Class C, Class I, Class N and Class Y shares, and previously offered Class B shares for new purchase through June 29, 2012. Subsequent to that date, no new purchases of Class B shares will be permitted, however reinvestment of dividend and/or capital gain distributions and exchanges of Class B shares into and from other Oppenheimer funds will be allowed. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Class C and Class N shares are sold, and Class B shares were 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 I and Class Y shares are sold to certain institutional investors or intermediaries without either a front-end sales charge or a CDSC, however, the intermediaries may impose charges on their accountholders who beneficially own Class I and Class Y shares. 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 shares have separate distribution and/or service plans under which they pay fees. Class I and Class Y shares do not pay such fees. Class B shares will automatically convert to Class A shares 72 months after the date of purchase. Class I shares were first publicly offered on April 27, 2012.

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

Previous Annual Period. The last day of the Fund’s fiscal year was the last day the New York Stock Exchange was open for trading. The Fund’s financial statements have been presented through that date to maintain consistency with the Fund’s net asset value calculations used for shareholder transactions.

Hybrid Instruments. The Fund invests in hybrid instruments 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 hybrid instruments 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 hybrid instrument is sold or matures.

26 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

Credit Risk. The Fund invests in high-yield, non-investment-grade bonds, which may be subject to a greater degree of credit risk. Credit risk relates to the ability of the issuer to meet interest or principal payments or both as they become due. The Fund may acquire securities that have missed an interest payment, and is not obligated to dispose of securities whose issuers or underlying obligors subsequently miss an interest payment. Information concerning securities not accruing interest as of December 31, 2012 is as follows:

Cost	$	398,721
Market Value	$	32,457
Market Value as a % of Net Assets		0.01	%

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 Manager and the Sub-Adviser.

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. Shares of the Subsidiary are valued at their net asset value per share. Gains or losses on withdrawals of capital from the Subsidiary by the Fund are recognized on an average cost 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 June of 2026. 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 year ended December 31, 2012, the Subsidiary has a deficit of $11,901,822 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.

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

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 27

NOTES TO FINANCIAL STATEMENTS    Continued

1. Significant Accounting Policies Continued

Company Act of 1940, as amended. The Manager is also the investment adviser of IMMF. When applicable, the Fund’s investment in IMMF is included in the Statement of Investments. Shares of IMMF are valued at their net asset value per share. 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.

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.

The tax components of capital shown in the following table represent distribution requirements the Fund must satisfy under the income tax regulations, losses the Fund may be able to offset against income and gains realized in future years and unrealized appreciation or depreciation of securities and other investments for federal income tax purposes.

1. As of December 31, 2012, the Fund had $573,084,667 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. Details of the capital loss carryforwards are included in the table below. Capital loss carryovers with no expiration, if any, must be utilized prior to those with expiration dates.

2. During the fiscal year ended December 31, 2012, the Fund did not utilize any capital loss carryforward.

3. During the fiscal year ended December 30, 2011, the Fund utilized $54,791,178 of capital loss carryforward to offset capital gains realized in that fiscal year.

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.

Accordingly, the following amounts have been reclassified for December 31, 2012. Net assets of the Fund were unaffected by the reclassifications.

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 December 31, 2012 are noted in the following table. The primary difference between book and tax appreciation or depreciation of securities and other investments, if applicable, is attributable to the tax deferral of losses or tax realization of financial statement unrealized gain or loss.

Federal tax cost of securities	$	983,639,203
Gross unrealized appreciation	$	18,359,456
Gross unrealized depreciation		(378,680,811	)
Net unrealized depreciation	$	(360,321,355	)

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 with the compensation deferral plan.

1. Significant Accounting Policies Continued

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.

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 (except for the investments in the Subsidiary) 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.

30 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

2. 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.

The Fund’s Board has adopted procedures for the valuation of the Fund’s securities and has delegated the day-to-day responsibility for valuation determinations under those procedures to the Manager. The Manager has established a Valuation Committee which is responsible for determining a “fair valuation” for any security for which market quotations are not “readily available.” The Valuation Committee’s fair valuation determinations are subject to review, approval and ratification by the Fund’s Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined.

Valuation Methods and Inputs

Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by third party pricing services or dealers.

The following methodologies are used to determine the market value or the fair value of the types of securities described below:

Securities traded on a registered U.S. securities exchange (including exchange-traded derivatives other than futures and futures options) are valued based on the last sale price of the security reported on the principal exchange on which it is traded, 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 security of a foreign issuer traded on a foreign exchange but not listed on a registered U.S. securities exchange is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the third party pricing service used by the Manager, prior to the time when the Fund’s assets are valued. If the last sale price is unavailable, the security is valued at the most recent official closing price on the principal exchange on which it is traded. If the last sales price or official closing price for a foreign security is not available, the security is valued at the mean between the bid and asked price per the exchange or, if not available from the exchange, obtained from two dealers. If bid and asked prices are not available from either the exchange or two dealers, the security is valued by using one of the following methodologies (listed in order of priority); (1) using a bid from the exchange, (2) the mean between the bid and asked price as provided by a single dealer, or (3) a bid from a single dealer.

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 and government debt securities (of U.S. or foreign issuers) and municipal debt securities, event-linked bonds, loans, mortgage-backed securities, collateralized mortgage obligations, and asset-backed securities are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers who may use matrix pricing methods to determine the evaluated prices.

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 31

NOTES TO FINANCIAL STATEMENTS    Continued

2. Securities Valuation Continued

Short-term money market type debt securities with a remaining maturity 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. Short-term debt securities with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers.

Hybrid instruments, swaps, swaptions, and other over-the-counter derivatives are valued utilizing evaluated prices obtained from third party pricing services or broker-dealers.

A description of the standard inputs that may generally be considered by the third party pricing vendors in determining their evaluated prices is provided below.

Security Type	Standard inputs generally considered by third-party pricing vendors
Corporate debt, government debt, municipal, mortgage-backed and asset-backed securities	Reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, and other appropriate factors.
Loans	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.
Hybrid instruments	Relevant market information such as the price of underlying financial instruments, stock market indices, foreign currencies, interest rate spreads, commodities, or the occurrence of other specific events.
Event-linked bonds	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.

If a market value or price cannot be determined for a security using the methodologies described above, or if, in the “good faith” opinion of the Manager, the market value or price obtained does not constitute a “readily available market quotation,” or a significant event has occurred that would materially affect the value of the security the security is fair valued either (i) by a standardized fair valuation methodology applicable to the security type or the significant event as previously approved by the Valuation Committee and the Fund’s Board or (ii) as determined in good faith by the Manager’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Manager, when determining the fair value of a security. Fair value determinations by the Manager are subject to review, approval and ratification by the Fund’s Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined. Those fair valuation standardized methodologies include, but are not limited to, valuing securities at the last sale price or 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 further adjusted for any discounts related to security-specific resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted 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 nor can it be assured that the Fund can obtain the fair value assigned to a security if it were to sell the security.

32 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

To assess the continuing appropriateness of security valuations, the Manager, or its third party service provider who is subject to oversight by the Manager, regularly compares prior day prices, prices on comparable securities, and sale prices to the current day prices and challenges those prices exceeding certain tolerance levels with the third party pricing service or broker source. For those securities valued by fair valuations, whether through a standardized fair valuation methodology or a fair valuation determination, the Valuation Committee reviews and affirms the reasonableness of the valuations based on such methodologies and fair valuation determinations on a regular basis after considering all relevant information that is reasonably available.

Classifications

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. 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—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)

2) Level 2—inputs other than unadjusted quoted prices that are observable for the asset or liability (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)

3) Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset or liability).

The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

The table below categorizes amounts that are included in the Fund’s Statement of Assets and Liabilities as of December 31, 2012 based on valuation input level:

and liabilities included in the above table are reported at their market value at measurement date.

There have been no significant changes to the fair valuation methodologies of the Fund 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.

Additionally, Class Y shares are subject to minimum fees of $10,000 annually for assets of $10 million or more. The Class Y shares are subject to the minimum fees in the event that the per account fee does not equal or exceed the applicable minimum fees. OFS may voluntarily waive the minimum fees.

Distribution and Service Plan (12b-1) Fees. Under its General Distributor’s Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the “Distributor”) acts as the Fund’s principal underwriter in the continuous public offering of the Fund’s classes of shares.

Service Plan for Class A Shares. The Fund has adopted a Service Plan (the “Plan”) for Class A shares under Rule 12b-1 of the Investment Company Act of 1940. Under the Plan, the Fund reimburses the Distributor for a portion of its costs incurred for services provided to accounts that hold Class A shares. Reimbursement is made periodically at an annual rate of up to 0.25% of the daily net assets of Class A shares of the Fund. The Distributor currently uses all of those fees to pay dealers, brokers, banks and other financial institutions periodically for providing personal service and maintenance of accounts of their customers that hold Class A shares. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent periods. Fees incurred by the Fund under the Plan are detailed in the Statement of Operations.

Distribution and Service Plans for Class B, 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 daily net assets and 0.25% on Class N shares daily net assets. 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

36 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

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. Fees incurred by the Fund under the Plans are detailed in the Statement of Operations. The Distributor determines its uncompensated expenses under the Plans at calendar quarter ends. The Distributor’s aggregate uncompensated expenses under the Plans at December 31, 2012 were as follows:

Class B	$	3,331,452
Class C		5,541,770
Class N		671,561

Sales Charges. Front-end sales charges and contingent deferred sales charges (“CDSC”) do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, as applicable. The sales charges retained by the Distributor from the sale of shares and the CDSC retained by the Distributor on the redemption of shares is shown in the following table for the period indicated.

Year Ended	Class A Front-End Sales Charges Retained by Distributor		Class A Contingent Deferred Sales Charges Retained by Distributor		Class B Contingent Deferred Sales Charges Retained by Distributor		Class C Contingent Deferred Sales Charges Retained by Distributor		Class N Contingent Deferred Sales Charges Retained by Distributor

Waivers and Reimbursements of Expenses. The Manager has contractually agreed to waive the management fee it receives from the Fund in an amount equal to the management fee it receives from the Subsidiary. This undertaking will continue in effect for so long as the Fund invests in the Subsidiary and may not be terminated unless approved by the Fund’s Board of Trustees. During the year ended December 31, 2012, the Manager waived $1,979,521.

The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investment in IMMF. During the year ended December 31, 2012, the Manager waived fees and/or reimbursed the Fund $350,414 for IMMF management fees.

OFS has voluntarily agreed to limit transfer and shareholder servicing agent fees for Classes B, C, N and Y shares to 0.35% of average annual net assets per class; this limit also applied to Class A shares prior to March 1, 2012. Effective March 1, 2012, OFS has voluntarily agreed to limit its fees for Class A shares to 0.30% of average annual net assets of the class.

During the year ended December 31, 2012, OFS waived transfer and shareholder servicing agent fees as follows:

Class A	$	359,321

Some of these undertakings may be modified or terminated at any time; some may not be modified or terminated until after one year from the date of the current prospectus, as indicated therein.

6. Restricted Securities

As of December 31, 2012, investments in securities included issues that are restricted. A restricted security may have a contractual restriction on its resale and is valued under methods approved by the Board of Trustees as reflecting fair value. Securities that are restricted are marked with an applicable footnote on the Statement of Investments. Restricted securities are reported on a schedule following the Statement of Investments.

7. Subsequent Event

The Board of Trustees of the Fund recently approved a series of modifications to the Fund’s investment advisory and transfer agency arrangements in connection with internal corporate restructuring efforts at OppenheimerFunds, Inc. (“OFI”). As a result of these modifications, on January 1, 2013 (the “Effective Date”), OFI Global Asset Management, Inc. (“OFI Global”), a wholly-owned subsidiary of OFI, became the investment adviser and transfer agent to the Fund under the terms of the Fund’s advisory agreement and transfer agency agreement, respectively. OFI Global, in turn, entered into a new sub-advisory agreement for the Fund, on the Effective Date, whereby OFI Global will have oversight and supervisory responsibilities and OFI will choose the Fund’s investments and provide related advisory services to the Fund. In addition, on the Effective Date, OFI Global entered into a sub-transfer agency agreement with Shareholder Services, Inc. doing business as OppenheimerFunds Services, a wholly-owned subsidiary of OFI, under which it will be responsible for providing transfer agency services to the Fund.

The realignment of advisory service responsibility between OFI Global and OFI did not result in any change in the persons managing the assets of the Fund, the level or nature of the advisory services provided to the Fund, or the fees charged to the Fund.

8. Pending Litigation

Since 2009, a number of class action lawsuits have been pending in federal courts against OppenheimerFunds, Inc., the Fund’s Adviser through December 31, 2012 and Sub-Advisor effective January 1, 2013 (the “Manager”), OppenheimerFunds Distributor, Inc., the Fund’s principal underwriter and distributor (the “Distributor”), and certain funds (but not including the Fund) advised by the Manager and distributed by the Distributor (the “Defendant Funds”). Several of these lawsuits also name as defendants certain officers and current and former trustees of the respective Defendant Funds. The lawsuits raise claims under federal securities law and allege, among other things, that the disclosure documents of the respective Defendant Funds contained misrepresentations and omissions and that the respective Defendant Funds’ investment policies were not followed. The plaintiffs in these actions seek unspecified damages, equitable relief and awards of attorneys’ fees and litigation expenses. The Defendant Funds’ Boards of Trustees have also engaged counsel to represent the Funds and the present and former Independent Trustees named in those suits.

38 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

Other class action and individual lawsuits have been filed since 2008 in various state and federal courts against the Manager and certain of its affiliates by investors seeking to recover investments they allegedly lost as a result of the “Ponzi” scheme run by Bernard L. Madoff and his firm, Bernard L. Madoff Investment Securities, LLC (“BLMIS”). Plaintiffs in these suits allege that they suffered losses as a result of their investments in several funds managed by an affiliate of the Manager and assert a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and awards of attorneys’ fees and litigation expenses. Neither the Distributor, nor any of the Oppenheimer mutual funds, their independent trustees or directors are named as defendants in these lawsuits. None of the Oppenheimer mutual funds invested in any funds or accounts managed by Madoff or BLMIS. On February 28, 2011, a stipulation of partial settlement of three groups of consolidated putative class action lawsuits relating to these matters was filed in the U.S. District Court for the Southern District of New York. On August 19, 2011, the court entered an order and final judgment approving the settlement as fair, reasonable and adequate. In September 2011, certain parties filed notices of appeal from the court’s order approving the settlement. The settlement does not resolve other outstanding lawsuits against the Manager and its affiliates relating to BLMIS.

On April 16, 2010, a lawsuit was filed in New York state court against the Manager, an affiliate of the Manager and AAArdvark IV Funding Limited (“AAArdvark IV”), an entity advised by the Manager’s affiliate, in connection with investments made by the plaintiffs in AAArdvark IV. Plaintiffs allege breach of contract against the defendants and seek compensatory damages, costs and disbursements, including attorney fees. On July 15, 2011, a lawsuit was filed in New York state court against the Manager, an affiliate of the Manager and AAArdvark Funding Limited (“AAArdvark I”), an entity advised by the Manager’s affiliate, in connection with investments made by the plaintiffs in AAArdvark I. The complaint alleges breach of contract against the defendants and seeks compensatory damages, costs and disbursements, including attorney fees. On November 9, 2011, a lawsuit was filed in New York state court against the Manager, an affiliate of the Manager and AAArdvark XS Funding Limited (“AAArdvark XS”), an entity advised by the Manager’s affiliate, in connection with investments made by the plaintiffs in AAArdvark XS. The complaint alleges breach of contract against the defendants and seeks compensatory damages, costs and disbursements, including attorney fees.

The Manager believes the lawsuits and appeals described above are without legal merit and, with the exception of actions it has settled, is defending against them vigorously. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer mutual funds.

BOARD APPROVAL OF THE FUND’S INVESTMENT

ADVISORY AND SUB-ADVISORY AGREEMENTS    Unaudited

Each year, the Board of Trustees (the “Board”), including a majority of the independent Trustees, is required to determine whether to renew the Fund’s investment advisory agreement and sub-advisory agreement (the “Agreements”). The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Manager and Oppenheimer Real Asset Management, Inc., (the “Sub-Adviser”) provide, such information as may be reasonably necessary to evaluate the terms of the Agreements. The Board employs an independent consultant to prepare a report that provides information, including comparative information that the Board requests for that purpose. In addition to in-person meetings focused on this evaluation, the Board receives information throughout the year regarding Fund services, fees, expenses and performance.

The Manager and the independent consultant provided information to the Board on the following factors: (i) the nature, quality and extent of the Manager’s and Sub-Adviser’s services, (ii) the investment performance of the Fund, the Manager and the Sub-Adviser, (iii) the fees and expenses of the Fund, including comparative expense information, (iv) the profitability of the Manager and its affiliates, including an analysis of the cost of providing services, and of the Sub-Adviser and the group of affiliates in which it participates (v) whether economies of scale are realized as the Fund grows and whether fee levels reflect these economies of scale for Fund investors and (vi) other benefits to the Manager and Sub-Adviser from their relationships with the Fund. The Board was aware that there are alternatives to retaining the Manager and the Sub-Adviser.

Outlined below is a summary of the principal information considered by the Board as well as the Board’s conclusions.

Nature, Quality and Extent of Services. The Board considered information about the nature, quality and extent of the services provided to the Fund and information regarding the Manager’s and Sub-Adviser’s key personnel who provide such services. The Sub-Adviser’s duties include providing the Fund with the services of the portfolio managers and the Sub-Adviser’s investment team, who provide research, analysis and other advisory services in regard to the Fund’s investments; securities trading services; oversight of third-party service providers; monitoring compliance with applicable Fund policies and procedures and adherence to the Fund’s investment restrictions; and risk management. The Manager and Sub-Adviser are responsible for providing certain administrative services to the Fund as well. Those services include providing and supervising all administrative and clerical personnel who are necessary in order to provide effective corporate administration for the Fund; compiling and maintaining records with respect to the Fund’s operations; preparing and filing reports required by the Securities and Exchange Commission; preparing periodic reports regarding the operations of the Fund for its shareholders;

42 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

preparing proxy materials for shareholder meetings; and preparing the registration statements required by Federal and state securities laws for the sale of the Fund’s shares. The Manager and Sub-Adviser also provide the Fund with office space, facilities and equipment.

The Board also considered the quality of the services provided and the quality of the Manager’s and Sub-Adviser’s resources that are available to the Fund. The Board took account of the fact that the Manager has had over fifty years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Manager’s and Sub-Adviser’s advisory, administrative, accounting, legal, compliance services and risk management, and information the Board has received regarding the experience and professional qualifications of the Manager’s and Sub-Adviser’s key personnel and the size and functions of their staff. In its evaluation of the quality of the portfolio management services provided, the Board considered the experience of Robert Baker and Carol Wolf, the portfolio managers for the Fund, and the Manager’s investment team and analysts. The Board members also considered the totality of their experiences with the Manager as directors or trustees of the Fund and other funds advised by the Manager. The Board considered information regarding the quality of services provided by affiliates of the Manager, which its members have become knowledgeable about in connection with the renewal of the Fund’s service agreements. The Board concluded, in light of the Manager’s and Sub-Adviser’s experience, reputation, personnel, operations and resources that the Fund benefits from the services provided under the Agreements.

Investment Performance of the Manager, Sub-Adviser and the Fund. Throughout the year, the Manager and Sub-Adviser provided information on the investment performance of the Fund, including comparative performance information. The Board also reviewed information, prepared by the Manager and by the independent consultant, comparing the Fund’s historical performance to relevant market indices and to the performance of other retail front-end load and no-load commodities general funds. The Board considered that Lipper does not have a performance universe for retail front-end load specialty diversified funds that, like the Fund, specialize in commodities. The Board considered the Manager’s assertion that Lipper’s performance information does not offer a good performance measurement for the Fund, since the funds in the performance universe do not invest in the same types of securities. The Board also considered management’s assertion that reviewing performance of the commodity-only portion of the Fund’s portfolio provides greater insight into the performance of the Fund with respect to active commodities management. The Board noted that the commodities-only portion of the

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 43

BOARD APPROVAL OF THE FUND’S INVESTMENT

ADVISORY AND SUB-ADVISORY AGREEMENTS    Unaudited / Continued

Fund outperformed its benchmark in the first quarter of 2011, and underperformed its benchmark in the second, third and fourth quarters of 2011. The Board considered that the Fund outperformed its performance universe median for the one-year period and equaled its performance universe median for the ten-year period, although it underperformed its performance universe median for the three- and five-year periods. The Board considered the Manager’s assertion that volatility and contango (the situation in which the price of a commodity for future delivery is higher than the expected future spot (or settlement-price) in futures for energy contracts negatively impacted the Fund’s performance for the three-year period. The Board also considered the Manager’s assertion that the Fund’s shift from the Core Plus Team to the Money Market Team in December 2008, has resulted in a more conservative approach to investing of the Fund’s cash positions.

Costs of Services by the Manager. The Board reviewed the fees paid to the Manager and the other expenses borne by the Fund. The Board noted that the Manager, not the Fund, pays the Sub-Adviser’s fee under the sub-advisory agreement. The Board also considered the comparability of the fees charged and the services provided to the Fund to the fees and services for other clients or accounts advised by the Manager. The independent consultant provided comparative data in regard to the fees and expenses of the Fund and other retail front-end load commodities general funds with comparable asset levels and distribution features. The Board noted that the Fund’s actual and contractual management fees, as well as its total expenses, were lower than its expense group median and average.

Economies of Scale and Profits Realized by the Manager and Sub-Adviser. The Board considered information regarding the Manager’s costs in serving as the Fund’s investment adviser, including the fee paid to the Sub-Adviser, the costs associated with the personnel and systems necessary to manage the Fund, and information regarding the Manager’s and Sub-Adviser’s profitability from their relationships with the Fund. The Board reviewed whether the Manager may realize economies of scale in managing and supporting the Fund. The Board noted that the Fund currently has management fee breakpoints, which are intended to share with Fund shareholders economies of scale that may exist as the Fund’s assets grow.

Other Benefits to the Manager and Sub-Adviser. In addition to considering the profits realized by the Manager and the Sub-Adviser, the Board considered information that was provided regarding the direct and indirect benefits the Manager and the Sub-Adviser receive as a result of their relationships with the Fund, including the fee paid to the Sub-Adviser, compensation paid to the Manager’s affiliates. The Board also

44 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

considered that the Manager and Sub-Adviser must be able to pay and retain experienced professional personnel at competitive rates to provide quality services to the Fund.

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

Based on its review of the information it received and its evaluations described above, the Board, including a majority of the independent Trustees, decided to continue the Agreement. In addition, the Board, including a majority of the Independent Trustees, approved the restructuring of the Fund’s investment advisory arrangement so that effective January 1, 2013, (i) OFI Global Asset Management, Inc. (“OFI Global”), a wholly owned subsidiary of the Manager, will serve as the investment adviser to the Fund in place of the Manager under a Restated Advisory Agreement (“Restated Advisory Agreement”), and (ii) OFI Global will enter into a Sub-Advisory Agreement (“Sub-Advisory Agreement”) with the Manager to provide investment sub-advisory services to the Fund. OFI Global will pay the Manager a percentage of the net investment advisory fee (after all applicable waivers have been deducted) that it receives from the Fund. The Agreement will continue until earlier of August 31, 2013 or the effective date of the Restated Advisory Agreement between the Fund and OFI Global. The Restated Advisory Agreement and Sub-Advisory Agreement will continue until August 31, 2013.

In arriving at its decisions, the Board did not single out any factor or factors as being more important than others, but considered all of the above information, and considered the terms and conditions of the Agreement, Restated Advisory Agreement and Sub-Advisory Agreement, including the management fees, in light of all the surrounding circumstances.

Householding—Delivery of Shareholder Documents

This is to inform you about OppenheimerFunds’ “householding” policy. If more than one member of your household maintains an account in a particular fund, OppenheimerFunds will mail only one copy of the fund’s prospectus (or, if available, the fund’s summary prospectus), annual and semiannual report and privacy policy. The consolidation of these mailings, called householding, benefits your fund through reduced mailing expense, and benefits you by reducing the volume of mail you receive from OppenheimerFunds. Householding does not affect the delivery of your account statements.

Please note that we will continue to household these mailings for as long as you remain an OppenheimerFunds shareholder, unless you request otherwise. If you prefer to receive multiple copies of these materials, please call us at 1.800.CALL-OPP (225-5677). You may also notify us in writing or via email. We will begin sending you individual copies of the prospectus (or, if available, the summary prospectus), reports and privacy policy within 30 days of receiving your request to stop householding.

RAF FUND LTD. (the “SUBSIDIARY”)

NOTES TO FINANCIAL STATEMENTS    

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 adviser is OppenheimerFunds, Inc. (the “Manager”). The Sub-Adviser is Oppenheimer Real Asset Management, Inc. (“ORAMI” or the “Sub-Adviser”), a wholly-owned subsidiary of the Manager. As of December 31, 2012, 100% of the Fund was owned by Oppenheimer Commodity Strategy Total Return Fund (“OCSTRF”). The Manager is also the investment adviser of OCSTRF and ORAMI is also the Sub-Adviser 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 December 31, 2012, the directors have not designated classes or series of outstanding participating shares. During the year ended December 31, 2012, 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.

Previous Annual Period. The last day of the Fund’s fiscal year was the last day the New York Stock Exchange was open for trading. The Fund’s financial statements have been presented through that date to maintain consistency with the Fund’s net asset value calculations used for shareholder transactions.

Credit Risk. The Fund invests in high-yield, non-investment-grade bonds, which may be subject to a greater degree of credit risk. Credit risk relates to the ability of the issuer to meet interest or principal payments or both as they become due. The Fund may acquire securities that have missed an interest payment, and is not obligated to dispose of securities whose issuers or underlying obligors subsequently miss an interest payment. Information concerning securities not accruing interest as of December 31, 2012 is as follows:

Cost	$	82,949
Market Value	$	19,187
Market Value as a % of Net Assets		0.01	%

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. When applicable, the Fund’s investment in IMMF is included in the

60 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

Statement of Investments. Shares of IMMF are valued at their net asset value per share. 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.

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 June of 2026. 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 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

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 61

RAF FUND LTD. (the “SUBSIDIARY”)

NOTES TO FINANCIAL STATEMENTS    Continued

1. Significant Accounting Policies Continued

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. 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.

The Fund’s Board has adopted procedures for the valuation of the Fund’s securities and has delegated the day-to-day responsibility for valuation determinations under those procedures to the Manager. The Manager has established a Valuation Committee which is responsible for determining a “fair valuation” for any security for which market quotations are not “readily available.” The Valuation Committee’s fair valuation determinations are subject to review, approval and ratification by the Fund’s Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined.

Valuation Methods and Inputs

Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by third party pricing services or dealers.

The following methodologies are used to determine the market value or the fair value of the types of securities described below:

Securities traded on a registered U.S. securities exchange (including exchange-traded derivatives other than futures and futures options) are valued based on the last sale price of the security reported on the principal exchange on which it is traded, 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 security of a foreign issuer traded on a foreign exchange but not listed on a registered U.S. securities exchange is valued based on the last sale price on the principal exchange on which the security is traded, as identified by the third party pricing service used by the Manager, prior to the time when the Fund’s assets are valued. If the last sale price is unavailable, the security is valued at the most recent official closing price on the principal exchange on which it is traded. If the last sales price or official closing price for a foreign security is not available, the security is valued at the mean between the bid and asked price per the exchange or, if not available from the exchange, obtained from two dealers. If bid and asked prices are not available from either the exchange or two dealers, the security is valued by using one of the following methodologies (listed in order of priority); (1) using a bid from the exchange, (2) the mean between the bid and asked price as provided by a single dealer, or (3) a bid from a single dealer.

62 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

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 and government debt securities (of U.S. or foreign issuers) and municipal debt securities, event-linked bonds, loans, mortgage-backed securities, collateralized mortgage obligations, and asset-backed securities are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers who may use matrix pricing methods to determine the evaluated prices.

Short-term money market type debt securities with a remaining maturity 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. Short-term debt securities with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing evaluated prices obtained from third party pricing services or broker-dealers.

Futures contracts and futures options 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.

A description of the standard inputs that may generally be considered by the third party pricing vendors in determining their evaluated prices is provided below.

Security Type	Standard inputs generally considered by third-party pricing vendors
Corporate debt, government debt, municipal, mortgage-backed and asset-backed securities	Reported trade data, broker-dealer price quotations, benchmark yields, issuer spreads on comparable securities, the credit quality, yield, maturity, and other appropriate factors.
Loans	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.
Event-linked bonds	Information obtained from market participants regarding reported trade data and broker-dealer price quotations.

If a market value or price cannot be determined for a security using the methodologies described above, or if, in the “good faith” opinion of the Manager, the market value or price obtained does not constitute a “readily available market quotation,” or a significant event has occurred that would materially affect the value of the security the security is fair valued either (i) by a standardized fair valuation methodology applicable to the security type or the significant event as previously approved by the Valuation Committee and the Fund’s Board or (ii) as determined in good faith by the Manager’s Valuation Committee. The Valuation Committee considers all relevant facts that are reasonably available, through either public information or information available to the Manager, when determining the fair value of a security. Fair value determinations by the Manager are subject to review, approval and ratification by the Fund’s Board at its next regularly scheduled meeting covering the calendar quarter in which the fair valuation was determined. Those fair valuation standardized methodologies include, but are not limited to, valuing securities at the last sale price or initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 63

RAF FUND LTD. (the “SUBSIDIARY”)

NOTES TO FINANCIAL STATEMENTS    Continued

2. Securities Valuation Continued

changes in the value of similar securities which may be further adjusted for any discounts related to security-specific resale restrictions. When possible, such methodologies use observable market inputs such as unadjusted 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 nor can it be assured that the Fund can obtain the fair value assigned to a security if it were to sell the security.

To assess the continuing appropriateness of security valuations, the Manager, or its third party service provider who is subject to oversight by the Manager, regularly compares prior day prices, prices on comparable securities, and sale prices to the current day prices and challenges those prices exceeding certain tolerance levels with the third party pricing service or broker source. For those securities valued by fair valuations, whether through a standardized fair valuation methodology or a fair valuation determination, the Valuation Committee reviews and affirms the reasonableness of the valuations based on such methodologies and fair valuation determinations on a regular basis after considering all relevant information that is reasonably available.

Classifications

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. 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—unadjusted quoted prices in active markets for identical assets or liabilities (including securities actively traded on a securities exchange)

2) Level 2—inputs other than unadjusted quoted prices that are observable for the asset or liability (such as unadjusted quoted prices for similar assets and market corroborated inputs such as interest rates, prepayment speeds, credit risks, etc.)

3) Level 3—significant unobservable inputs (including the Manager’s own judgments about assumptions that market participants would use in pricing the asset or liability).

The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities.

All additional assets and liabilities included in the above table are reported at their market value at measurement date.

Waivers and Reimbursements of Expenses. The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investments in IMMF. During the year ended December 31, 2012, the Manager waived fees and/or reimbursed the Fund $59,370 for management fees.

Some of these undertakings may be modified or terminated at any time.

5. Risk Exposures and the Use of Derivative Instruments

The Fund’s investment objectives not only permit the Fund to purchase investment securities, they also allow the Fund to enter into various types of derivatives contracts, including, but not limited to, futures contracts, forward foreign currency exchange contracts, credit default swaps, interest rate swaps, total return swaps, and purchased and written options. In doing so, the Fund will employ strategies in differing combinations to

66 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

permit it to increase, decrease, or change the level or types of exposure to market risk factors. Central to those strategies are features inherent to derivatives that make them more attractive for this purpose than equity and debt securities: they require little or no initial cash investment, they can focus exposure on only certain selected risk factors, and they may not require the ultimate receipt or delivery of the underlying security (or securities) to the contract. This may allow the Fund to pursue its objectives more quickly and efficiently than if it were to make direct purchases or sales of securities capable of effecting a similar response to market factors.

Market Risk Factors. In accordance with its investment objectives, the Fund may use derivatives to increase or decrease its exposure to one or more of the following market risk factors:

Commodity Risk. Commodity risk relates to the change in value of commodities or commodity indexes as they relate to increases or decreases in the commodities market. Commodities are physical assets that have tangible properties. Examples of these types of assets are crude oil, heating oil, metals, livestock, and agricultural products.

Credit Risk. Credit risk relates to the ability of the issuer to meet interest and principal payments, or both, as they come due. In general, lower-grade, higher-yield bonds are subject to credit risk to a greater extent than lower-yield, higher-quality bonds.

Equity Risk. Equity risk relates to the change in value of equity securities as they relate to increases or decreases in the general market.

Foreign Exchange Rate Risk. Foreign exchange rate risk relates to the change in the U.S. dollar value of a security held that is denominated in a foreign currency. The U.S. dollar value of a foreign currency denominated security will decrease as the dollar appreciates against the currency, while the U.S. dollar value will increase as the dollar depreciates against the currency.

Interest Rate Risk. Interest rate risk refers to the fluctuations in value of fixed-income securities resulting from the inverse relationship between price and yield. For example, an increase in general interest rates will tend to reduce the market value of already issued fixed-income investments, and a decline in general interest rates will tend to increase their value. In addition, debt securities with longer maturities, which tend to have higher yields, are subject to potentially greater fluctuations in value from changes in interest rates than obligations with shorter maturities.

Volatility Risk. Volatility risk refers to the magnitude of the movement, but not the direction of the movement, in a financial instrument’s price over a defined time period. Large increases or decreases in a financial instrument’s price over a relative time period typically indicate greater volatility risk, while small increases or decreases in its price typically indicate lower volatility risk.

The Fund’s actual exposures to these market risk factors during the period are discussed in further detail, by derivative type, below.

Risks of Investing in Derivatives. The Fund’s use of derivatives can result in losses due to unanticipated changes in the market risk factors and the overall market. In instances where

OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND 67

NOTES TO FINANCIAL STATEMENTS    Continued

5. Risk Exposures and the Use of Derivative Instruments Continued

the Fund is using derivatives to decrease, or hedge, exposures to market risk factors for securities held by the Fund, there are also risks that those derivatives may not perform as expected resulting in losses for the combined or hedged positions.

Derivatives may have little or no initial cash investment relative to their market value exposure and therefore can produce significant gains or losses in excess of their cost. This use of embedded leverage allows the Fund to increase its market value exposure relative to its net assets and can substantially increase the volatility of the Fund’s performance.

Additional associated risks from investing in derivatives also exist and potentially could have significant effects on the valuation of the derivative and the Fund. Typically, the associated risks are not the risks that the Fund is attempting to increase or decrease exposure to, per its investment objectives, but are the additional risks from investing in derivatives. Examples of these associated risks are liquidity risk, which is the risk that the Fund will not be able to sell the derivative in the open market in a timely manner, and counterparty credit risk, which is the risk that the counterparty will not fulfill its obligation to the Fund. Associated risks can be different for each type of derivative and are discussed by each derivative type in the notes that follow.

Valuations of derivative instruments as of December 31, 2012 are as follows:

*Includes purchased option contracts and purchased swaption contracts, if any.

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.

The Fund has purchased futures contracts, which have values that are linked to the price movement of the related commodities, in order to increase exposure to commodity risk.

The Fund has sold futures contracts, which have values that are linked to the price movement of the related commodities, in order to decrease exposure to commodity risk.

During the year ended December 31, 2012, the Fund had an ending monthly average market value of $537,671,325 and $68,011,377 on futures contracts purchased and sold, respectively.

Additional associated risks of entering into futures contracts (and related options) include the possibility that there may be an illiquid market where the Fund is unable to liquidate the contract or enter into an offsetting position 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. Risk Exposures and the Use of Derivative Instruments Continued

Option Activity

The Fund may buy and sell put and call options, or write put and 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.

The Fund has purchased put options on individual commodities to decrease exposure to commodity risk. A purchased put option becomes more valuable as the price of the underlying financial instrument depreciates relative to the strike price.

The Fund has purchased call options on individual commodities to increase exposure to commodity risk. A purchased call option becomes more valuable as the price of the underlying financial instrument appreciates relative to the strike price.

During the year ended December 31, 2012, the Fund had an average market value of $340,065 and $74,052 on purchased call options and purchased put options, respectively.

Options written, if any, are reported in a schedule following the Statement of Investments and as a liability in the Statement of Assets and Liabilities. Securities held in collateralized accounts to cover potential obligations with respect to outstanding written options are noted in the Statement of Investments.

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.

The Fund has written put options on individual commodities to increase exposure to commodity risk. A written put option becomes more valuable as the price of the underlying financial instrument appreciates relative to the strike price.

The Fund has written call options on individual commodities to decrease exposure to commodity risk. A written call option becomes more valuable as the price of the underlying financial instrument depreciates relative to the strike price.

During the year ended December 31, 2012, the Fund had an ending monthly average market value of $105,285 and $39,629 on written call options and written put options, respectively.

8. Subsequent Event

The Board of Trustees of the Fund recently approved a series of modifications to the Fund’s investment advisory and transfer agency arrangements in connection with internal corporate restructuring efforts at OppenheimerFunds, Inc. (“OFI”). As a result of these modifications, on January 1, 2013 (the “Effective Date”), OFI Global Asset Management, Inc. (“OFI Global”), a wholly-owned subsidiary of OFI, became the investment adviser and transfer agent to the Fund under the terms of the Fund’s advisory agreement and transfer agency agreement, respectively. OFI Global, in turn, entered into a new sub-advisory agreement for the Fund, on the Effective Date, whereby OFI Global will have oversight and supervisory responsibilities and OFI will choose the Fund’s investments and provide related advisory services to the Fund. As of the Effective Date, ORAMI will no longer be a

72 OPPENHEIMER COMMODITY STRATEGY TOTAL RETURN FUND

sub-adviser to the Fund. In addition, on the Effective Date, OFI Global entered into a sub-transfer agency agreement with Shareholder Services, Inc. doing business as OppenheimerFunds Services, a wholly-owned subsidiary of OFI, under which it will be responsible for providing transfer agency services to the Fund.

The realignment of advisory service responsibility between OFI Global and OFI did not result in any change in the persons managing the assets of the Fund, the level or nature of the advisory services provided to the Fund, or the fees charged to the Fund.

9. Pending Litigation

Since 2009, a number of class action lawsuits have been pending in federal courts against OppenheimerFunds, Inc., the Fund’s Adviser through December 31, 2012 and Sub-Advisor effective January 1, 2013 (the “Manager”), OppenheimerFunds Distributor, Inc., the Fund’s principal underwriter and distributor (the “Distributor”), and certain funds (but not including the Fund) advised by the Manager and distributed by the Distributor (the “Defendant Funds”). Several of these lawsuits also name as defendants certain officers and current and former trustees of the respective Defendant Funds. The lawsuits raise claims under federal securities law and allege, among other things, that the disclosure documents of the respective Defendant Funds contained misrepresentations and omissions and that the respective Defendant Funds’ investment policies were not followed. The plaintiffs in these actions seek unspecified damages, equitable relief and awards of attorneys’ fees and litigation expenses. The Defendant Funds’ Boards of Trustees have also engaged counsel to represent the Funds and the present and former Independent Trustees named in those suits.

Other class action and individual lawsuits have been filed since 2008 in various state and federal courts against the Manager and certain of its affiliates by investors seeking to recover investments they allegedly lost as a result of the “Ponzi” scheme run by Bernard L. Madoff and his firm, Bernard L. Madoff Investment Securities, LLC (“BLMIS”). Plaintiffs in these suits allege that they suffered losses as a result of their investments in several funds managed by an affiliate of the Manager and assert a variety of claims, including breach of fiduciary duty, fraud, negligent misrepresentation, unjust enrichment, and violation of federal and state securities laws and regulations, among others. They seek unspecified damages, equitable relief and awards of attorneys’ fees and litigation expenses. Neither the Distributor, nor any of the Oppenheimer mutual funds, their independent trustees or directors are named as defendants in these lawsuits. None of the Oppenheimer mutual funds invested in any funds or accounts managed by Madoff or BLMIS. On February 28, 2011, a stipulation of partial settlement of three groups of consolidated putative class action lawsuits relating to these matters was filed in the U.S. District Court for the Southern District of New York. On August 19, 2011, the court entered an order and final judgment approving the settlement as fair, reasonable and adequate. In September 2011, certain parties filed notices of appeal from the court’s order approving the settlement. The settlement does not resolve other outstanding lawsuits against the Manager and its affiliates relating to BLMIS.

NOTES TO FINANCIAL STATEMENTS    Continued

9. Pending Litigation Continued

On April 16, 2010, a lawsuit was filed in New York state court against the Manager, an affiliate of the Manager and AAArdvark IV Funding Limited (“AAArdvark IV”), an entity advised by the Manager’s affiliate, in connection with investments made by the plaintiffs in AAArdvark IV. Plaintiffs allege breach of contract against the defendants and seek compensatory damages, costs and disbursements, including attorney fees. On July 15, 2011, a lawsuit was filed in New York state court against the Manager, an affiliate of the Manager and AAArdvark Funding Limited (“AAArdvark I”), an entity advised by the Manager’s affiliate, in connection with investments made by the plaintiffs in AAArdvark I. The complaint alleges breach of contract against the defendants and seeks compensatory damages, costs and disbursements, including attorney fees. On November 9, 2011, a lawsuit was filed in New York state court against the Manager, an affiliate of the Manager and AAArdvark XS Funding Limited (“AAArdvark XS”), an entity advised by the Manager’s affiliate, in connection with investments made by the plaintiffs in AAArdvark XS. The complaint alleges breach of contract against the defendants and seeks compensatory damages, costs and disbursements, including attorney fees.

The Manager believes the lawsuits and appeals described above are without legal merit and, with the exception of actions it has settled, is defending against them vigorously. While it is premature to render any opinion as to the outcome in these lawsuits, or whether any costs that the Defendant Funds may bear in defending the suits might not be reimbursed by insurance, the Manager believes that these suits should not impair the ability of the Manager or the Distributor to perform their respective duties to the Fund, and that the outcome of all of the suits together should not have any material effect on the operations of any of the Oppenheimer mutual funds.

INDEPENDENT AUDITORS’ REPORT

The Board of Directors RAF Fund, Ltd.:

We have audited the accompanying financial statements of RAF Fund Ltd., which comprise the statement of assets and liabilities, including the statement of investments, as of December 31, 2012, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, the financial highlights for each of the years in the four-year period then ended, and the related notes to the financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly in all material respects, the financial position of RAF Fund Ltd. as of December 31, 2012, the results of its

EX-99.CODE ETH

CODE OF ETHICS

FOR PRINCIPAL EXECUTIVE AND FINANCIAL OFFICERS

OF THE OPPENHEIMER FUNDS

AND OPPENHEIMERFUNDS, INC.

This Code of Ethics for Principal Executive and Financial Officers (referred to in this document as the “Code”) has been adopted by each of the investment companies for which OppenheimerFunds, Inc. or one of its subsidiaries or affiliates (referred to collectively in this document as “OFI”) acts as investment adviser (individually, a “Fund” and collectively, the “Funds”), and by OFI to effectuate compliance with Section 406 under the Sarbanes-Oxley Act of 2002 and the rules adopted to implement Section 406.

This Code applies to OFI’s and each Fund’s principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions (“Covered Officers”). A listing of positions currently within the ambit of Covered Officers is attached as Exhibit A.¹

1. Purpose of the Code

This Code sets forth standards and procedures that are reasonably designed to deter wrongdoing and promote:

• honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

• full, fair, accurate, timely, and understandable disclosure in reports and documents that a Fund files with, or submits to, the U.S. Securities and Exchange Commission (“SEC”) and in other public communications made by the Fund;

• compliance with applicable governmental laws, rules and regulations;

• the prompt internal reporting of violations of this Code to the Code Administrator identified below; and

• accountability for adherence to this Code.

In general, the principles that govern honest and ethical conduct, including the avoidance of conflicts of interest between personal and professional relationships, reflect, at the minimum, the following: (1) the duty at all times in performing any responsibilities as a Fund financial officer, controller, accountant or principal executive officer to place the interests of the Funds ahead of personal interests; (2) the fundamental standard that Covered Officers should not take inappropriate advantage of their positions; (3) the duty to assure that a Fund’s financial statements and reports to its shareholders are prepared honestly and accurately in accordance with applicable rules, regulations and accounting standards; and (4) the duty to conduct the Funds’ business and affairs in an honest and ethical manner. Each Covered Officer should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

¹  The obligations imposed by this Code on Covered Officers are separate from and in addition to any obligations that may be imposed on such persons as Covered Persons under the Code of Ethics adopted by OFI and the Funds under Rule 17j-1 of the Investment Company Act of 1940, as amended and any other code of conduct applicable to Covered Officers in whatever capacity they serve. This Code does not incorporate by reference any provisions of the Rule 17j-1 Code of Ethics and accordingly, any violations or waivers granted under the Rule 17j-1 Code of Ethics will not be considered a violation or waiver under this Code.

It is acknowledged that, as a result of the contractual relationship between each Fund and OFI, of which the Covered Officers are also officers or employees, and subject to OFI’s fiduciary duties to each Fund, the Covered Officers will, in the normal course of their duties, be involved in establishing policies and implementing decisions that will have different effects on OFI and the Funds. It is further acknowledged that the participation of the Covered Officers in such activities is inherent in the contractual relationship between each Fund and OFI and is consistent with the expectations of the Board of Trustees/Directors of the performance by the Covered Officers of their duties as officers of the Funds.

2. Prohibitions

The specific provisions and reporting requirements of this Code are concerned primarily with promoting honest and ethical conduct and avoiding conflicts of interest in personal and professional relationships. No Covered Officer may use information concerning the business and affairs of a Fund, including the investment intentions of a Fund, or use his or her ability to influence such investment intentions, for personal gain to himself or herself, his or her family or friends or any other person or in a manner detrimental to the interests of a Fund or its shareholders.

No Covered Officer may use his or her personal influence or personal relationships to influence the preparation and issuance of financial reports of a Fund whereby the Covered Officer would benefit personally to the detriment of the Fund and its shareholders.

No Covered Officer shall intentionally for any reason take any action or fail to take any action in connection with his or her official acts on behalf of a Fund that causes the Fund to violate applicable laws, rules and regulations.

No Covered Officer shall, in connection with carrying out his or her official duties and responsibilities on behalf of a Fund:

(i) employ any device, scheme or artifice to defraud a Fund or its shareholders;

(ii) intentionally cause a Fund to make any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the circumstances under which they are made, not misleading in its official documents, regulatory filings, financial statements or communications to the public;

(iii) engage in any act, practice, or course of business which operates or would operate as a fraud or deceit upon any Fund or its shareholders;

(iv) engage in any manipulative practice with respect to any Fund;

(v) use his or her personal influence or personal relationships to influence any business decision, investment decisions, or financial reporting by a Fund whereby the Covered Officer would benefit personally to the detriment of the Fund or its shareholders;

(vi) intentionally cause a Fund to fail to comply with applicable laws, rules and regulations, including failure to comply with the requirement of full, fair, accurate, understandable and timely disclosure in reports and documents that a Fund files with, or submits to, the SEC and in other public communications made by the Fund;

(vii) intentionally mislead or omit to provide material information to the Fund’s independent auditors or to the Board of Trustees/Directors or the officers of the Fund or its investment adviser in connection with financial reporting matters;

(viii) fail to notify the Code Administrator or the Chief Executive Officer of the Fund or its investment adviser promptly if he or she becomes aware of any existing or potential violations of this Code or applicable laws;

(ix) retaliate against others for, or otherwise discourage the reporting of, actual or apparent violations of this Code; or

(x) fails to acknowledge or certify compliance with this Code if requested to do so.

3. Reports of Conflicts of Interests

If a Covered Officer becomes aware of a conflict of interest under this Code or, to the Covered Officer’s reasonable belief, the appearance of one, he or she must immediately report the matter to the Code’s Administrator. If the Code Administrator is involved or believed to be involved in the conflict of interest or appearance of conflict of interest, the Covered Officer shall report the matter directly to the OFI’s Chief Executive Officer.

Upon receipt of a report of a conflict, the Code Administrator will take prompt steps to determine whether a conflict of interest exists. If the Code Administrator determines that an actual conflict of interest exists, the Code Administrator will take steps to resolve the conflict. If the Code Administrator determines that the appearance of a conflict exists, the Code Administrator will take appropriate steps to remedy such appearance. If the Code Administrator determines that no conflict or appearance of a conflict exists, the Code Administrator shall meet with the Covered Officer to advise him or her of such finding and of his or her reason for taking no action. In lieu of determining whether a conflict or appearance of conflict exists, the Code Administrator may in his or her discretion refer the matter to the Fund’s Board of Trustees/Directors.

4. Waivers

Any Covered Officer requesting a waiver of any of the provisions of this Code must submit a written request for such waiver to the Code Administrator, setting forth the basis of such request and all necessary facts upon which such request can be evaluated. The Code Administrator shall review such request and make a written determination thereon, which shall be binding. The Code Administrator may in reviewing such request, consult at his discretion with legal counsel to OFI or to the Fund.

In determining whether to waive any of the provisions of this Code, the Code Administrator shall consider whether the proposed waiver:

(i) is prohibited by this Code;

(ii) is consistent with honest and ethical conduct; and

(iii) will result in a conflict of interest between the Covered Officer’s personal and professional obligations to a Fund.

In lieu of determining whether to grant a waiver, the Code Administrator in his or her discretion may refer the matter to the appropriate Fund’s Board of Trustees/Directors.

5. Reporting Requirements

(a) Each Covered Officer shall, upon becoming subject to this Code, be provided with a copy of this Code and shall affirm in writing that he or she has received, read, understands and shall adhere to this Code.

(b) At least annually, all Covered Officers shall be provided with a copy of this Code and shall certify that they have read and understand this Code and recognize that they are subject thereto.

(c) At least annually, all Covered Officers shall certify that they have complied with the requirements of this Code and that they have disclosed or reported any violations of this Code to the Code Administrator or the Chief Executive Officer of the Fund or its investment adviser.

(d) The Code Administrator shall submit a quarterly report to the Board of Trustees/Directors of each Fund containing (i) a description of any report of a conflict of interest or apparent conflict and the disposition thereof; (ii) a description of any request for a waiver from this Code and the disposition thereof; (iii) any violation of the Code that has been reported or found and the sanction imposed; (iv) interpretations issued under the Code by the Code Administrator; and (v) any other significant information arising under the Code including any proposed amendments.

(e) Each Covered Officer shall notify the Code Administrator promptly if he or she knows of or has a reasonable belief that any violation of this Code has occurred or is likely to occur. Failure to do so is itself a violation of this Code.

(f) Any changes to or waivers of this Code, including “implicit” waivers as defined in applicable SEC rules, will, to the extent required, be disclosed by the Code Administrator or his or her designee as provided by applicable SEC rules.²

6. Annual Review

At least annually, the Board of Trustees/Directors of each Fund shall review the Code and consider whether any amendments are necessary or desirable.

7. Sanctions

Any violation of this Code of Ethics shall be subject to the imposition of such sanctions by OFI as may be deemed appropriate under the circumstances to achieve the purposes of this Code and may include, without limitation, a letter of censure, suspension from employment or termination of employment, in the sole discretion of OFI.

8. Administration and Construction

(a) The administration of this Code of Ethics shall be the responsibility of OFI’s General Counsel or his designee as the “Code Administrator” of this Code, acting under the terms of this Code and the oversight of the Trustees/Directors of the Funds.

(b) The duties of such Code Administrator will include:

(i) Continuous maintenance of a current list of the names of all Covered Officers;

(ii) Furnishing all Covered Officers a copy of this Code and initially and periodically informing them of their duties and obligations thereunder;

(iii) Maintaining or supervising the maintenance of all records required by this Code, including records of waivers granted hereunder;

(iv) Issuing interpretations of this Code which appear to the Code Administrator to be consistent with the objectives of this Code and any applicable laws or regulations;

(c) In carrying out the duties and responsibilities described under this Code, the Code Administrator may consult with legal counsel, who may include legal counsel to the applicable Funds, and such other persons as the Administrator shall deem necessary or desirable. The Code Administrator shall be protected from any liability hereunder or under any applicable law, rule or regulation, for decisions made in good faith based upon his or her reasonable judgment.

²  An “implicit waiver” is the failure to take action within a reasonable period of time regarding a material departure from a provision of this Code that has been made known to the General Counsel, the Code Administrator, and an executive officer of the Fund or OFI.

9. Required Records

The Administrator shall maintain and cause to be maintained in an easily accessible place, the following records for the period required by applicable SEC rules (currently six years following the end of the fiscal year of OFI in which the applicable event or report occurred):
