The percentages above are based on the market value of the Fund’s securities as of November 30, 2011, and are subject to change. Except for securities labeled “Unrated,” and except for certain securities issued or guaranteed by a foreign sovereign or supranational entity, all securities have been rated by at least one Nationally Recognized Statistical Rating Organization (“NRSRO”), such as Standard & Poor’s (“S&P”). For securities rated only by an NRSRO other than S&P, OppenheimerFunds, Inc. converts that rating to the equivalent S&P rating. If two or more NRSROs have assigned a rating to a security, the highest S&P equivalent rating is used. Unrated securities issued or guaranteed by a sovereign entity are assigned a credit rating equal to the highest NRSRO rating assigned to that sovereign entity. U.S. Government “Treasury” and “Agency” securities are included in the AAA category. Fund assets invested in Oppenheimer Institutional Money Market Fund are assigned that fund’s S&P rating, which is currently AAA. For the purposes of this Credit Allocation table, “investment-grade” securities are securities rated within the NRSROs’ four highest rating categories, which include AAA, AA, A and BBB. Unrated securities do not necessarily indicate low credit quality, and may or may not be the equivalent of investment-grade. Please consult the Fund’s prospectus for further information. Additional information can be found in the Fund’s Statement of Additional Information.

NOTES

Total returns include changes in share price and reinvestment of dividends and capital gains distributions in a hypothetical investment for the periods shown. Cumulative total returns are not annualized. The Fund’s total returns shown do not reflect the deduction of income taxes on an individual’s investment. Taxes may reduce your actual investment returns on income or gains paid by the Fund or any gains you may realize if you sell your shares.

Before investing in any of the Oppenheimer funds, investors should carefully consider a fund’s investment objectives, risks, charges and expenses. Fund prospectuses and summary prospectuses contain this and other information about the funds, and may be obtained by asking your financial advisor, visiting oppenheimerfunds.com, or calling 1.800.CALL OPP (225.5677). Read prospectuses and summary prospectuses carefully before investing.

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

Class A shares of the Fund were first publicly offered on 6/30/10. Unless otherwise noted, Class A returns include the current maximum initial sales charge of 4.75%.

Class C shares of the Fund were first publicly offered on 6/30/10. Unless otherwise noted, Class C returns include the contingent deferred sales charge of 1%. Class C shares are subject to an annual 0.75% asset-based sales charge.

Class N shares of the Fund were first publicly offered on 6/30/10. Class N shares are offered only through retirement plans. Unless otherwise noted, Class N returns include the contingent deferred sales charge of 1%. Class N shares are subject to an annual 0.25% asset-based sales charge.

Class Y shares of the Fund were first publicly offered on 6/30/10. Class Y shares are offered only to fee-based clients of dealers that have a special agreement with the Distributor, to certain institutional investors under a special agreement with the Distributor, and to present or former officers, directors, trustees or employees (and their eligible family members) of the Fund, the Manager, its affiliates, its parent company and the subsidiaries of its parent company, and retirement plans established for the benefit of such individuals. There is no sales charge for Class Y shares.

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

FUND EXPENSES

Fund Expenses. As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, which may include sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions and (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 November 30, 2011.

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		1,017.55		7.61
Class Y		1,000.00		1,020.41		4.72

Expenses are equal to the Fund’s annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period). Those annualized expense ratios, excluding indirect expenses from affiliated fund, based on the 6-month period ended November 30, 2011 are as follows:

Class	Expense Ratios
Class A		1.20	%
Class C		1.97
Class N		1.50
Class Y		0.93

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.

Valuation Inputs

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

1) Level 1—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).

NOTES TO FINANCIAL STATEMENTS Unaudited

1. Significant Accounting Policies

Oppenheimer Emerging Markets Debt 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”). As of November 30, 2011, approximately 33% of the shares of the Fund were owned by the Manager, other funds advised or sub-advised by the Manager or an affiliate of the Manager.

     The Fund offers Class A, Class C, Class N and Class Y shares. Class A shares are sold at their offering price, which is normally net asset value plus a front-end sales charge. Class C and Class N shares are sold without a front-end sales charge but may be subject to a contingent deferred sales charge (“CDSC”). Class N shares are sold only through retirement plans. Retirement plans that offer Class N shares may impose charges on those accounts. Class Y shares are sold to certain institutional investors 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 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, C and N shares have separate distribution and/or service plans under which they pay fees. Class Y shares do not pay such fees.

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

Securities Valuation. The Fund calculates the net asset value of its shares as of the close of the New York Stock Exchange (the “Exchange”), normally 4:00 P.M. Eastern time, on each day the Exchange is open for trading.

     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. Unadjusted quoted prices in active markets for identical securities are classified as “Level 1,” observable market inputs other than unadjusted quoted prices are classified as “Level 2” and significant unobservable inputs, including the Manager’s judgment about the assumptions that a market participant would use in pricing an asset or liability, are classified as “Level 3.” The inputs used for valuing securities are not necessarily an indication of the risks associated with investing in those securities. A table summarizing the Fund’s investments under these levels of classification is included following the Statement of Investments.

     Securities are valued using unadjusted quoted market prices, when available, as supplied primarily by portfolio pricing services approved by the Board of Trustees or dealers.

     Securities traded on a registered U.S. securities exchange are valued based on the last sale price of the security reported on the principal exchange on which it is traded, prior to the time when the Fund’s assets are valued. Securities whose principal exchange is NASDAQ ® are valued based on the official closing prices reported by NASDAQ prior to the time when the Fund’s assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the current day’s

40 | OPPENHEIMER EMERGING MARKETS DEBT FUND

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

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

     U.S. domestic and international debt instruments (including corporate, government, municipal, mortgage-backed, collateralized mortgage obligations and asset-backed securities) and “money market-type” debt instruments with a remaining maturity in excess of sixty days are valued at the mean between the “bid” and “asked” prices utilizing price quotations obtained from independent pricing services or broker-dealers. Such prices are typically determined based upon information obtained from market participants including reported trade data, broker-dealer price quotations and inputs such as benchmark yields and issuer spreads from identical or similar securities.

     Structured securities are valued utilizing price quotations obtained from broker-dealers or independent pricing services. Values are determined based upon market inputs which typically include the price of underlying financial instruments, stock market indices, foreign currencies, interest rate spreads, commodities, or the occurrence of other specific events.

     Swap contracts are valued utilizing price quotations obtained from broker-dealer counterparties or independent pricing services. Values are determined based on relevant market information on the underlying reference assets which may include credit spreads, credit event probabilities, index values, individual security values, forward interest rates, variable interest rates, volatility measures and forward currency rates.

     Forward foreign currency exchange contracts are valued utilizing current and forward currency rates obtained from independent pricing services.

     “Money market-type” debt instruments with remaining maturities of sixty days or less are valued at cost adjusted by the amortization of discount or premium to maturity (amortized cost), which approximates market value.

     In the absence of a current price quotation obtained from an independent pricing service or broker-dealer, including for securities whose values have been materially affected by what the Manager identifies as a significant event occurring before the Fund’s assets are valued but after the close of the securities’ respective exchanges, the Manager, acting through its internal valuation committee, in good faith determines the fair valuation of that asset using consistently applied procedures under the supervision of the Board of Trustees (which reviews those fair valuations by the Manager). Those procedures include certain standardized methodologies to fair value securities. Such methodologies include, but are not limited to, pricing securities initially at cost and subsequently adjusting the value based on: changes in company specific fundamentals, changes in an appropriate securities index, or changes in the value of similar securities which may be adjusted for any discounts related to resale restrictions. When possible, such methodologies use observable market

inputs such as 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.

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

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

Securities on a When-Issued or Delayed Delivery Basis. The Fund may purchase securities on a “when-issued” basis, and may purchase or sell securities on a “delayed delivery” basis. “When-issued” or “delayed delivery” refers to securities whose terms and indenture are available and for which a market exists, but which are not available for immediate delivery. Delivery and payment for securities that have been purchased by the Fund on a when-issued basis normally takes place within six months and possibly as long as two years or more after the trade date. During this period, such securities do not earn interest, are subject to market fluctuation and may increase or decrease in value prior to their delivery. The purchase of securities on a when-issued basis may increase the volatility of the Fund’s net asset value to the extent the Fund executes such transactions while remaining substantially fully invested. When the Fund engages in when-issued or delayed delivery transactions, it relies on the buyer or seller, as the case may be, to complete the transaction. Their failure to do so may cause the Fund to lose the opportunity to obtain or dispose of the security at a price and yield it considers advantageous. The Fund may also sell securities that it purchased on a when-issued basis or forward commitment prior to settlement of the original purchase.

As of November 30, 2011, the Fund had purchased securities issued on a when-issued or delayed delivery basis as follows:

	When-Issued or
	Delayed Delivery
	Basis Transactions
Purchased securities	$	64,303

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

42 | OPPENHEIMER EMERGING MARKETS DEBT FUND

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 November 30, 2011 is as follows:

Cost	$	7,050
Market Value	$	7,725
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 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.

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

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

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

Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class.

Federal Taxes. The Fund intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company taxable income, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders. Therefore, no federal income or excise tax provision is required. The Fund files income tax returns in U.S. federal and applicable state jurisdictions. The statute of limitations on the Fund’s tax return filings generally remain open for the three preceding fiscal reporting period ends.

     During the fiscal year ended May 31, 2011, the Fund did not utilize any capital loss carryforward to offset capital gains realized in that fiscal year. As of May 31, 2011, the Fund had post-October losses of $514,305 which have no expiration date.

     As of November 30, 2011, the Fund generated additional estimated capital losses of $100,633 which will be carried forward to future years if not offset by gains in the remaining six months of the Fund’s fiscal year. When increased by capital loss carryforwards in existence at May 31, 2011, the Fund had estimated capital loss carryforwards of $614,938 which will not expire. During the six months ended November 30, 2011, it is estimated that the Fund will not utilize any capital loss carryforward to offset realized capital gains.

     Net investment income (loss) and net realized gain (loss) may differ for financial statement and tax purposes. The character of dividends and distributions made during the fiscal year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. Also, due to timing of dividends and distributions, the fiscal year in which amounts are distributed may differ from the fiscal year in which the income or net realized gain was recorded by the Fund.

The aggregate cost of securities and other investments and the composition of unrealized appreciation and depreciation of securities and other investments for federal income tax purposes as of November 30, 2011 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	$	64,302,788
Federal tax cost of other investments		(4,502,593	)
Total federal tax cost	$	59,800,195
Gross unrealized appreciation	$	912,567
Gross unrealized depreciation		(4,637,812	)
Net unrealized depreciation	$	(3,725,245	)

Certain foreign countries impose a tax on capital gains which is accrued by the Fund based on unrealized appreciation, if any, on affected securities. The tax is paid when the gain is realized.

The Regulated Investment Company Modernization Act of 2010 (the “Act”) was signed into law on December 22, 2010. The Act makes changes to a number of tax rules impacting

44 | OPPENHEIMER EMERGING MARKETS DEBT FUND

the Fund. Although the Act provides a number of benefits, including the unlimited carryover of future capital losses, there may be a greater likelihood that all or a portion of a fund’s prior year capital loss carryovers will expire unused. In general, the provisions of the Act will be effective for the Fund’s fiscal year ending 2012. Specific information regarding the impact of the Act on the Fund will be contained within the “Federal Taxes” section of the financial statement notes for the fiscal year ending 2012.

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.

Dividends and Distributions to Shareholders. Dividends and distributions to shareholders, which are determined in accordance with income tax regulations and may differ from U.S. generally accepted accounting principles, are recorded on the ex-dividend date. Income distributions, if any, are declared daily and paid monthly. Capital gain distributions, if any, are declared and paid annually. The tax character of distributions is determined as of the Fund’s fiscal year end. Therefore, a portion of the Fund’s distributions made to shareholders prior to the Fund’s fiscal year end may ultimately be categorized as a tax return of capital.

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 estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

2. Shares of Beneficial Interest

The Fund has authorized an unlimited number of $0.001 par value shares of beneficial interest of each class. Transactions in shares of beneficial interest were as follows:

4. Fees and Other Transactions with Affiliates

Management Fees. Under the investment advisory agreement, the Fund pays the Manager a management fee based on the daily net assets of the Fund at an annual rate as shown in the following table:

Fee Schedule
Up to $500 million	0.75	%
Next $500 million	0.70
Next $4 billion	0.65
Over $5 billion	0.60

Administration Service Fees. The Fund pays the Manager a fee of $1,500 per year for preparing and filing the Fund’s tax returns.

Transfer Agent Fees. OppenheimerFunds Services (“OFS”), a division of the Manager, acts as the transfer and shareholder servicing agent for the Fund. The Fund pays OFS a per account fee. For the six months ended November 30, 2011, the Fund paid $50,198 to OFS for services to the Fund.

     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.

4. Fees and Other Transactions with Affiliates Continued

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 C and Class N Shares. The Fund has adopted Distribution and Service Plans (the “Plans”) for 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 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 C or Class N plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. 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 September 30, 2011 were as follows:

Class C	$	85,311
Class N		7,633

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.

Waivers and Reimbursements of Expenses. The Manager has agreed to voluntarily waive a portion of its management fees and/or reimburse the Fund for certain expenses so that “Expenses after payments, waivers and/or reimbursements and reduction to custodian expenses” will not exceed 1.25% of average annual net assets for Class A shares, 2.00% for Class C shares, 1.50% for Class N shares and 0.95% for Class Y shares. During the six months ended November 30, 2011, the Manager reimbursed the Fund $15,762, $670 and $6,338 for Class C, Class N and Class Y shares, respectively.

     The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund’s investment in IMMF. During the six months ended November 30, 2011, the Manager waived fees and/or reimbursed the Fund $1,291 for IMMF management fees.

     OFS has voluntarily agreed to limit transfer and shareholder servicing agent fees for all classes to 0.35% of average annual net assets per class.

During the six months ended November 30, 2011, OFS waived transfer and shareholder servicing agent fees as follows:

Class C	$	1,574
Class Y		762

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.

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 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.

49 | OPPENHEIMER EMERGING MARKETS DEBT FUND

NOTES TO FINANCIAL STATEMENTS Unaudited / Continued

5. Risk Exposures and the Use of Derivative Instruments Continued

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 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.

50 | OPPENHEIMER EMERGING MARKETS DEBT FUND

Associated risks can be different for each type of derivative and are discussed by each derivative type in the notes that follow.

Counterparty Credit Risk. Certain derivative positions are subject to counterparty credit risk, which is the risk that the counterparty will not fulfill its obligation to the Fund. The Fund’s derivative counterparties are financial institutions who are subject to market conditions that may weaken their financial position. The Fund intends to enter into financial transactions with counterparties that the Manager believes to be creditworthy at the time of the transaction. As of November 30, 2011, the maximum amount of loss that the Fund would incur if the counterparties to its derivative transactions failed to perform would be $930,789, which represents gross payments to be received by the Fund on these derivative contracts were they to be unwound as of period end. To reduce this risk the Fund has entered into master netting arrangements, established within the Fund’s International Swap and Derivatives Association, Inc. master agreements, which allow the Fund to net unrealized appreciation and depreciation for certain positions in swaps, over-the-counter options, swaptions, and forward currency exchange contracts for each individual counterparty. The amount of loss that the Fund would incur taking into account these master netting arrangements would be $415,125 as of November 30, 2011. In addition, the Fund may require that certain counterparties post cash and/or securities in collateral accounts to cover their net payment obligations for those derivative contracts subject to International Swap and Derivatives Association, Inc. master agreements. If the counterparty fails to perform under these contracts and agreements, the cash and/or securities will be made available to the Fund.

     As of November 30, 2011 the Fund has required certain counterparties to post collateral of $606,217.

Credit Related Contingent Features. The Fund’s agreements with derivative counterparties have several credit related contingent features that if triggered would allow its derivatives counterparties to close out and demand payment or additional collateral to cover their exposure from the Fund. Credit related contingent features are established between the Fund and its derivatives counterparties to reduce the risk that the Fund will not fulfill its payment obligations to its counterparties. These triggering features include, but are not limited to, a percentage decrease in the Fund’s net assets and or a percentage decrease in the Fund’s Net Asset Value or NAV. The contingent features are established within the Fund’s International Swap and Derivatives Association, Inc. master agreements which govern certain positions in swaps, over-the-counter options and swaptions, and forward currency exchange contracts for each individual counterparty.

     As of November 30, 2011, the aggregate fair value of derivative instruments with credit related contingent features in a net liability position was $246,690 for which collateral was not posted by the Fund. If a contingent feature would have been triggered as of November 30, 2011, the Fund could have been required to pay this amount in cash to its counterparties.

Foreign Currency Exchange Contracts

The Fund may enter into foreign currency exchange contracts (“forward contracts”) for the purchase or sale of a foreign currency at a negotiated rate at a future date.

     Forward contracts are reported on a schedule following the Statement of Investments. Forward contracts will be valued daily based upon the closing prices of the forward currency rates determined at the close of the Exchange as provided by a bank, dealer or pricing service. The resulting unrealized appreciation (depreciation) is reported in the Statement of Assets and Liabilities as a receivable or payable and in the Statement of Operations within the change in unrealized appreciation (depreciation). At contract close, the difference between the original cost of the contract and the value at the close date is recorded as a realized gain (loss) in the Statement of Operations.

     The Fund has purchased and sold certain forward foreign currency exchange contracts of different currencies in order to acquire currencies to pay for or sell currencies to acquire related foreign securities purchase and sale transactions, respectively, or to convert foreign currencies to U.S. dollars from related foreign securities transactions. These foreign currency exchange contracts are negotiated at the current spot exchange rate with settlement typically within two business days thereafter.

     The Fund has entered into forward foreign currency exchange contracts with the obligation to purchase specified foreign currencies in the future at a currently negotiated forward rate in order to take a positive investment perspective on the related currency. These forward foreign currency exchange contracts seek to increase exposure to foreign exchange rate risk.

     The Fund has entered into forward foreign currency exchange contracts with the obligation to purchase specified foreign currencies in the future at a currently negotiated forward rate in order to decrease exposure to foreign exchange rate risk associated with foreign currency denominated securities held by the Fund.

     The Fund has entered into forward foreign currency exchange contracts with the obligation to sell specified foreign currencies in the future at a currently negotiated forward rate in order to take a negative investment perspective on the related currency. These forward foreign currency exchange contracts seek to increase exposure to foreign exchange rate risk.

     The Fund has entered into forward foreign currency exchange contracts with the obligation to sell specified foreign currencies in the future at a currently negotiated forward rate in order to decrease exposure to foreign exchange rate risk associated with foreign currency denominated securities held by the Fund.

     During the six months ended November 30, 2011, the Fund had daily average contract amounts on forward foreign currency contracts to buy and sell of $28,174,989 and $28,681,655, respectively.

     Additional associated risk to the Fund includes counterparty credit risk. Counterparty credit risk arises from the possibility that the counterparty will default.

Futures Contracts

A futures contract is a commitment to buy or sell a specific amount of a financial instrument, or currency, at a negotiated price on a stipulated future date. The Fund may buy and sell futures contracts and 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 the variation margin are noted in the Statement of Assets and Liabilities. The net change in unrealized appreciation and 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 on various bonds and notes to increase exposure to interest rate risk.

     The Fund has sold futures contracts on various bonds and notes to decrease exposure to interest rate risk.

     During the six months ended November 30, 2011, the Fund had an ending monthly average market value of $1,567,353 and $12,470,315 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.

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.

54 | OPPENHEIMER EMERGING MARKETS DEBT FUND

     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 call options on currencies to increase exposure to foreign exchange rate risk. A purchased call option becomes more valuable as the price of the underlying financial instrument appreciates relative to the strike price.

     The Fund has purchased put options on currencies to decrease exposure to foreign exchange rate risk. A purchased put option becomes more valuable as the price of the underlying financial instrument depreciates relative to the strike price.

     During the six months ended November 30, 2011, the Fund had an ending monthly average market value of $9,821 and $46,514 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 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 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 currencies to increase exposure to foreign exchange rate 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 currencies to decrease exposure to foreign exchange rate risk. A written call option becomes more valuable as the price of the underlying financial instrument depreciates relative to the strike price.

     During the six months ended November 30, 2011, the Fund had an ending monthly average market value of $11,093 and $34,672 on written call options and written put options, respectively.

     Additional associated risks to the Fund include counterparty credit risk for over-the-counter options and liquidity risk.

Swap Contracts

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

     Swaps are marked to market daily using primarily quotations from pricing services, counterparties and brokers. Swap contracts are reported on a schedule following the Statement of Investments. The values of swap contracts are aggregated by positive and negative values and disclosed separately on the Statement of Assets and Liabilities by contracts in unrealized appreciation and depreciation positions. Upfront payments paid or received, if any, affect the value of the respective swap. Therefore, to determine the unrealized appreciation (depreciation) on swaps, upfront payments paid should be subtracted from, while upfront payments received should be added to, the value of contracts reported as an asset on the Statement of Assets and Liabilities. Conversely, upfront payments paid should be added to, while upfront payments received should be subtracted from the value of contracts reported as a liability. The unrealized appreciation (depreciation) related to the change in the valuation of the notional amount of the swap is combined with the accrued interest due to (owed by) the Fund at termination or settlement. The net change in this amount during the period is included on the Statement of Operations. The Fund also records any periodic payments received from (paid to) the counterparty, including at termination, under such contracts as realized gain (loss) on the Statement of Operations.

     Swap contract agreements are exposed to the market risk factor of the specific underlying reference asset. Swap contracts are typically more attractively priced compared to similar investments in related cash securities because they isolate the risk to one market risk factor and eliminate the other market risk factors. Investments in cash securities (for instance bonds) have exposure to multiple risk factors (credit and interest rate risk). Because swaps require little or no initial cash investment, they can expose the Fund to substantial risk in the isolated market risk factor.

Credit Default Swap Contracts. A credit default swap is a bilateral contract that enables an investor to buy or sell protection on a debt security against a defined-issuer

56 | OPPENHEIMER EMERGING MARKETS DEBT FUND

credit event, such as the issuer’s failure to make timely payments of interest or principal on the debt security, bankruptcy or restructuring. The Fund may enter into credit default swaps either by buying or selling protection on a single security or a basket of securities (the “reference asset”).

     The buyer of protection pays a periodic fee to the seller of protection based on the notional amount of debt securities underlying the swap contract. The seller of protection agrees to compensate the buyer of protection for future potential losses as a result of a credit event on the reference asset. The contract effectively transfers the credit event risk of the reference asset from the buyer of protection to the seller of protection.

     The ongoing value of the contract will fluctuate throughout the term of the contract based primarily on the credit risk of the reference asset. If the credit quality of the reference asset improves relative to the credit quality at contract initiation, the buyer of protection may have an unrealized loss greater than the anticipated periodic fee owed. This unrealized loss would be the result of current credit protection being cheaper than the cost of credit protection at contract initiation. If the buyer elects to terminate the contract prior to its maturity, and there has been no credit event, this unrealized loss will become realized. If the contract is held to maturity, and there has been no credit event, the realized loss will be equal to the periodic fee paid over the life of the contract.

     If there is a credit event, the buyer of protection can exercise its rights under the contract and receive a payment from the seller of protection equal to the notional amount of the reference asset less the market value of the reference asset. Upon exercise of the contract the difference between the value of the underlying reference asset and the notional amount is recorded as realized gain (loss) and is included on the Statement of Operations.

     The Fund has sold credit protection through credit default swaps to increase exposure to the credit risk of individual securities and/or, indexes that are either unavailable or considered to be less attractive in the bond market.

     The Fund has purchased credit protection through credit default swaps to decrease exposure to the credit risk of individual securities and/or, indexes.

     For the six months ended November 30, 2011, the Fund had ending monthly average notional amounts of $875,000 and $746,143 on credit default swaps to buy protection and credit default swaps to sell protection, respectively.

     Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

     Interest Rate Swap Contracts. An interest rate swap is an agreement between counterparties to exchange periodic payments based on interest rates. One cash flow stream will typically be a floating rate payment based upon a specified interest rate while the other is typically a fixed interest rate.

5. Risk Exposures and the Use of Derivative Instruments Continued

     The Fund has entered into interest rate swaps in which it pays a floating interest rate and receives a fixed interest rate in order to increase exposure to interest rate risk. Typically, if relative interest rates rise, payments made by the Fund under a swap agreement will be greater than the payments received by the Fund.

     The Fund has entered into interest rate swaps in which it pays a fixed interest rate and receives a floating interest rate in order to decrease exposure to interest rate risk. Typically, if relative interest rates rise, payments received by the Fund under the swap agreement will be greater than the payments made by the Fund.

     For the six months ended November 30, 2011, the Fund had ending monthly average notional amounts of $2,192,277 and $19,933,535 on interest rate swaps which pay a fixed rate and interest rate swaps which receive a fixed rate, respectively.

     Additional associated risks to the Fund include counterparty credit risk and liquidity risk.

6. Restricted Securities

As of November 30, 2011, 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. Pending Litigation

Since 2009, a number of class action, derivative and individual lawsuits have been pending in federal and state courts against OppenheimerFunds, Inc., the Fund’s investment advisor (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 laws and various states’ securities, consumer protection and common 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. On June 1, 2011, the U.S. District Court for the District of Colorado gave preliminary approval to stipulations and agreements of settlement in certain putative class action lawsuits involving two Defendant Funds, Oppenheimer Champion Income Fund and Oppenheimer Core Bond Fund. On September 30, 2011, the court entered orders and final judgments approving the settlements as fair, reasonable and adequate. Those

58 | OPPENHEIMER EMERGING MARKETS DEBT FUND

orders are not subject to further appeal. These settlements do not resolve other outstanding lawsuits relating to Oppenheimer Champion Income Fund and Oppenheimer Core Bond Fund, nor do the settlements affect certain other putative class action lawsuits pending in federal court against the Manager, the Distributor, and other Defendant Funds and their independent trustees.

     In 2009, what are claimed to be derivative lawsuits were filed in New Mexico state court against the Manager and a subsidiary (but not against the Fund) on behalf of the New Mexico Education Plan Trust challenging a settlement reached in 2010 between the Manager, its subsidiary and the Distributor and the board of the New Mexico section 529 college savings plan. These lawsuits allege breach of contract, breach of fiduciary duty, negligence and violation of state securities laws, and seek compensatory damages, equitable relief and an award of attorneys’ fees and litigation expenses. On September 9, 2011, the court denied plaintiffs’ request for a hearing to determine the fairness of the settlement, finding that plaintiffs lacked standing to pursue derivative claims on behalf of the Trust. On October 27, 2011, the parties to these actions filed a joint motion to dismiss the lawsuits with prejudice, which the court granted on October 28, 2011.

     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. On July 29, 2011, a stipulation of settlement between certain affiliates of the Manager and the Trustee appointed under the Securities Investor Protection Act to liquidate BLMIS was filed in the U.S. Bankruptcy Court for the Southern District of New York to resolve purported preference and fraudulent transfer claims by the Trustee. On September 22, 2011, the court entered an order approving the settlement as fair, reasonable and adequate. In October 2011, certain parties filed notices of appeal from the court’s order approving the settlement. The aforementioned settlements do not resolve other outstanding lawsuits against the Manager and its affiliates relating to BLMIS.

7. 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. 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. 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 AGREEMENT Unaudited

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

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

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

61 | OPPENHEIMER EMERGING MARKETS DEBT FUND

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

     The Board also considered the quality of the services provided and the quality of the Manager’s resources that are available to the Fund. The Board took account of the fact that the Manager has had over 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 advisory, administrative, accounting, legal and compliance services, and information the Board has received regarding the experience and professional qualifications of the Manager’s key personnel and the size and functions of its staff. In its evaluation of the quality of the portfolio management services provided, the Board considered the experience of Sara Zervos, the portfolio manager 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 experience, reputation, personnel, operations and resources that the Fund benefits from the services provided under the Agreement.

     Investment Performance of the Manager and the Fund. Throughout the year, the Manager provided information on the investment performance of the Fund and the Manager, 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 emerging markets debt funds. The Board considered that the Fund outperformed its performance universe median during the period since the Fund’s inception.

     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 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 emerging markets debt funds with comparable asset levels and distribution features. The Board considered that the Fund’s total expenses were equal to its expense group median, although its actual management fees were higher than its expense group median. The Board also considered that the Manager has agreed to voluntarily limit the total annual operating expenses for all classes of shares of the Fund so that total expenses, as percentage of average daily net assets, will not exceed the following annual rates: 1.25% for Class A Shares; 2.00% for Class C Shares; 1.50% for Class N Shares; and 0.95% for

62 | OPPENHEIMER EMERGING MARKETS DEBT FUND

Class Y Shares. This waiver and/or reimbursement may not be amended or withdrawn until one year after the date of the prospectus.

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

     Other Benefits to the Manager. In addition to considering the profits that may be realized by the Manager, the Board considered information that was provided regarding the direct and indirect benefits the Manager may receive as a result of its relationship with the Fund, including compensation paid to the Manager’s affiliates. The Board also considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide quality services to the Fund.

     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 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, approved the Agreement through August 31, 2012. In arriving at this decision, 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, including the management fee, in light of all of 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.

PRIVACY POLICY NOTICE

As an Oppenheimer fund shareholder, you are entitled to know how we protect your personal information and how we limit its disclosure.

Information Sources

We obtain nonpublic personal information about our shareholders from the following sources:

• Applications or other forms

• When you create a user ID and password for online account access

• When you enroll in eDocs Direct, our electronic document delivery service

• Your transactions with us, our affiliates or others

• A software program on our website, often referred to as a “cookie,” which indicates which parts of our site you’ve visited

• When you set up challenge questions to reset your password online

If you visit oppenheimerfunds.com and do not log on to the secure account information areas, we do not obtain any personal information about you. When you do log on to a secure area, we do obtain your user ID and password to identify you. We also use this information to provide you with products and services you have requested, to inform you about products and services that you may be interested in and assist you in other ways.

We do not collect personal information through our website unless you willingly provide it to us, either directly by email or in those areas of the website that request information. In order to update your personal information (including your mailing address, email address and phone number) you must first log on and visit your user profile.

If you have set your browser to warn you before accepting cookies, you will receive the warning message with each cookie. You can refuse cookies by turning them off in your browser. However, doing so may limit your access to certain sections of our website.

We use cookies to help us improve and manage our website. For example, cookies help us recognize new versus repeat visitors to the site, track the pages visited, and enable some special features on the website. This data helps us provide a better service for our website visitors.

Protection of Information

We do not disclose any non-public personal information (such as names on a customer list) about current or former customers to anyone, except as permitted by law.

Disclosure of Information

We send your financial advisor (as designated by you) copies of confirmations, account statements and other documents reporting activity in your fund accounts. We may also use details about you and your investments to help us, our financial service affiliates, or firms that jointly market their financial products and services with ours, to better serve your investment needs or suggest financial services or educational material that may be of interest to you. If this requires us to provide you with an opportunity to “opt in” or “opt out” of such information sharing with a firm not affiliated with us, you will receive notification on how to do so, before any such sharing takes place.

Right of Refusal

We will not disclose your personal information to unaffiliated third parties (except as permitted by law), unless we first offer you a reasonable opportunity to refuse or “opt out” of such disclosure.

Internet Security and Encryption

In general, the email services provided by our website are encrypted and provide a secure and private means of communication with us. To protect your own privacy, confidential and/or personal information should only be communicated via email when you are advised that you are using a secure website.

As a security measure, we do not include personal or account information in non-secure emails, and we advise you not to send such information to us in non-secure emails. Instead, you may take advantage of the secure features of our website to encrypt your email correspondence. To do this, you will need to use a browser that supports Secure Sockets Layer (SSL) protocol.

We do not guarantee or warrant that any part of our website, including files available for download, are free of viruses or other harmful code. It is your responsibility to take appropriate precautions, such as use of an anti-virus software package, to protect your computer hardware and software.

• All transactions, including redemptions, exchanges and purchases, are secured by SSL and 128-bit encryption. SSL is used to establish a secure connection between your PC and OppenheimerFunds’ server. It transmits information in an encrypted and scrambled format.

• Encryption is achieved through an electronic scrambling technology that uses a “key” to code and then decode the data. Encryption acts like the cable converter box you may have on your television set. It scrambles data with a secret code so that no one can make sense of it while it is being transmitted. When the data reaches its destination, the same software unscrambles the data.

• You can exit the secure area by either closing your browser, or for added security, you can use the Log Out button before you close your browser.

Other Security Measures

We maintain physical, electronic and procedural safeguards to protect your personal account information. Our employees and agents have access to that information only so that they may offer you products or provide services, for example, when responding to your account questions.

How You Can Help

You can also do your part to keep your account information private and to prevent unauthorized transactions. If you obtain a user ID and password for your account, do not allow it to be used by anyone else. Also, take special precautions when accessing your account on a computer used by others.

The Fund’s Governance Committee Provisions with Respect to Nominations of Directors/Trustees to the Respective Boards

1.	The Fund’s Governance Committee (the “Committee”) will evaluate potential Board candidates to assess their qualifications. The Committee shall have the authority, upon approval of the Board, to retain an executive search firm to assist in this effort. The Committee may consider recommendations by business and personal contacts of current Board members and by executive search firms which the Committee may engage from time to time and may also consider shareholder recommendations. The Committee may consider the advice and recommendation of the Funds’ investment manager and its affiliates in making the selection.
2.	The Committee shall screen candidates for Board membership. The Committee has not established specific qualifications that it believes must be met by a trustee nominee. In evaluating trustee nominees, the Committee considers, among other things, an individual’s background, skills, and experience; whether the individual is an “interested person” as defined in the Investment Company Act of 1940; and whether the individual would be deemed an “audit committee financial expert” within the meaning of applicable SEC rules. The Committee also considers whether the individual’s background, skills, and experience will complement the background, skills, and experience of other nominees and will contribute to the Board. There are no differences in the manner in which the Committee evaluates nominees for trustees based on whether the nominee is recommended by a shareholder.
3.	The Committee may consider nominations from shareholders for the Board at such times as the Committee meets to consider new nominees for the Board. The Committee shall have the sole discretion to determine the candidates to present to the Board and, in such cases where required, to shareholders. Recommendations for trustee nominees should, at a minimum, be accompanied by the following:

•	the name, address, and business, educational, and/or other pertinent background of the person being recommended;
•	a statement concerning whether the person is an “interested person” as defined in the Investment Company Act of 1940;
•	any other information that the Funds would be required to include in a proxy statement concerning the person if he or she was nominated; and
•	the name and address of the person submitting the recommendation and, if that person is a shareholder, the period for which that person held Fund shares.
The recommendation also can include any additional information which the person submitting it believes would assist the Committee in evaluating the recommendation.

4.

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

5.

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

Item 11. Controls and Procedures.

Based on their evaluation of the registrant’s disclosure controls and procedures (as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR 270.30a-3(c)) as of 11/30/2011, the registrant’s principal executive officer and principal financial officer found the registrant’s disclosure controls and procedures to provide reasonable assurances that information required to be disclosed by the registrant in the reports that it files under the Securities Exchange Act of 1934 (a) is accumulated and communicated to registrant’s management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure, and (b) is recorded, processed, summarized and reported, within the time periods specified in the rules and forms adopted by the U.S. Securities and Exchange Commission.

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

Item 12. Exhibits.

(a)	(1) Not applicable to semiannual reports.
	(2) Exhibits attached hereto.
	(3) Not applicable.
(b)	Exhibit attached hereto.
