Example. The following Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in a class of shares of the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your expenses would be as follows:

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 111% of the average value of its portfolio.

Principal Investment Strategies. The Fund invests mainly in debt securities of foreign government and corporate issuers. A debt security is a security representing money borrowed by the issuer that must be repaid. The terms of a debt security specify the amount of principal, the interest rate or discount, and the time or times at which payments are due. The Fund can invest in various types of debt securities, generally referred to as "bonds," including government bonds, corporate debt obligations, "structured" notes, participation interests in loans, "zero coupon" or "stripped" securities, certain mortgage-related securities or asset-backed securities and other debt obligations.

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in debt securities. The Fund typically invests in at least three countries other than the United States. The Fund invests in debt securities of issuers in both developed and emerging markets throughout the world.

The Fund may buy securities issued by companies of any size or market capitalization range and at times might emphasize securities of issuers in a particular capitalization range. It can invest in debt securities having short, intermediate or long maturities.

The Fund does not limit its investments to a particular credit quality or rating category and can invest without limit in securities rated below investment grade (commonly called "junk bonds"). "Investment grade" debt securities are rated in one of the top four categories by nationally recognized statistical rating organizations such as Moody's Investors Service or Standard & Poor's. The Fund may also invest in unrated securities, in which case the Fund's investment Sub-Adviser, OppenheimerFunds, Inc., may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade or below-investment-grade categories similar to those of nationally recognized statistical rating organizations. There can be no assurance, nor is it intended, that the Sub-Adviser's credit analysis is consistent or comparable with the credit analysis process used by a nationally recognized statistical rating organization.

The Fund may also use derivatives to seek increased returns or to try to manage investment risks, including, for example, options, forward contracts, futures contracts, swaps, and "structured" notes. The Fund actively manages foreign currency exposure, both to reduce risk and to seek to enhance return. To do so, the Fund may invest in foreign exchange derivatives, including forwards and options that reference foreign currencies, including currencies of developing and emerging market countries.

In selecting securities, the portfolio managers evaluate the overall investment opportunities and risks in individual national economies. The portfolio managers analyze the business cycle, political and macro-economic factors that affect exchange rates and interest rates in both emerging market and developing countries. The portfolio managers currently focus on investment opportunities for higher yields than are available in U.S. markets and opportunities in investments denominated in foreign currencies that compare favorably to the U.S. dollar. These factors may vary in particular cases and may change over time.

Principal Risks. The price of the Fund's shares can go up and down substantially. The value of the Fund's investments may change because of broad changes in the markets in which the Fund invests or because of poor investment selection, which could cause the Fund to underperform other funds with similar investment objectives. There is no assurance that the Fund will achieve its investment objective. When you redeem your shares, they may be worth more or less than what you paid for them. These risks mean that you can lose money by investing in the Fund.

Main Risks of Debt Securities. Debt securities may be subject to credit risk, interest rate risk, prepayment risk, extension risk and event risk. Credit risk is the risk that the issuer of a security might not make interest and principal payments on the security as they become due. If an issuer fails to pay interest or repay principal, the Fund's income or share value might be reduced. Adverse news about an issuer or a downgrade in an issuer's credit rating, for any reason, can also reduce the market value of the issuer's securities. Interest rate risk is the risk that when prevailing interest rates fall, the values of already-issued debt securities generally rise; and when prevailing interest rates rise, the values of already-issued debt securities generally fall, and they may be worth less than the amount the Fund paid for them. When interest rates change, the values of longer-term debt securities usually change more than the values of shorter-term debt securities. When interest rates fall, debt securities may be repaid more quickly than expected and the Fund may be required to reinvest the proceeds at a lower interest rate. This is referred to as "prepayment risk." When interest rates rise, debt securities may be repaid more slowly than expected and the value of the Fund's holdings may fall sharply. This is referred to as "extension risk." Interest rate changes normally have different effects on variable or floating rate securities than they do on securities with fixed interest rates. Event risk is the risk that an issuer could be subject to an event, such as a buyout or debt restructuring, that interferes with its ability to make timely interest and principal payments and cause the value of its debt securities to fall.

Special Risks of Lower-Grade Securities. Lower-grade securities, whether rated or unrated, may be subject to wider market fluctuation, greater credit risk and greater risk of loss of income and principal than investment-grade securities. The market for lower-grade securities may be less liquid and therefore they may be harder to sell at an acceptable price, especially during times of market volatility or decline.

Because the Fund can invest without limit in lower-grade securities, the Fund's credit risks are greater than those of funds that buy only investment-grade securities.

Fixed-Income Market Risks . Economic and other market developments can adversely affect fixed-income securities markets in the United States, Europe and elsewhere. At times, participants in debt securities markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns can cause increased volatility in those debt securities or debt securities markets. Under some circumstances, as was the case during the latter half of 2008 and early 2009, those concerns could cause reduced liquidity in certain debt securities markets. A lack of liquidity or other adverse credit market conditions may hamper the Fund's ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments.

Special Risks of Sovereign Debt. Sovereign debt instruments are subject to the risk that a governmental entity may delay or refuse, or otherwise be unable, to pay interest or repay principal on its sovereign debt. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of such sovereign debt may be collected. A restructuring or default of sovereign debt may also cause additional impacts to the financial markets, such as downgrades to credit ratings, a flight to quality debt instruments, disruptions in common trading markets or unions, reduced liquidity, increased volatility, and heightened financial sector, foreign securities and currency risk, among others.

Main Risks of Foreign Investing. Foreign securities are subject to special risks. Foreign issuers are usually not subject to the same accounting and disclosure requirements that U.S. companies are subject to, which may make it difficult for the Fund to evaluate a foreign company's operations or financial condition. A change in the value of a foreign currency against the U.S. dollar will result in a change in the U.S. dollar value of securities denominated in that foreign currency and in the value of any income or distributions the Fund may receive on those securities. The value of foreign investments may be affected by exchange control regulations, foreign taxes, higher transaction and other costs, delays in the settlement of transactions, changes in economic or monetary policy in the United States or abroad, expropriation or nationalization of a company's assets, or other political and economic factors. These risks may be greater for investments in developing or emerging market countries.

Foreign Currency Risk. Fluctuations in foreign currency values will result in fluctuations in the U.S. dollar value of securities denominated in that foreign currency. If the U.S. dollar rises in value against a foreign currency, a security denominated in that currency will be worth less in U.S. dollars and if the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency will be worth more in U.S. dollars. The dollar value of foreign investments may also be affected by exchange controls.

The portfolio manager's selection of foreign currency denominated investments may not perform as expected. Currency derivative investments may be particularly volatile and subject to greater risks than other types of foreign-currency denominated investments.

Special Risks of Developing and Emerging Markets. The economies of developing or emerging market countries may be more dependent on relatively few industries that may be highly vulnerable to local and global changes. The governments of developing and emerging market countries may also be more unstable than the governments of more developed countries. These countries generally have less developed securities markets or exchanges, and less developed legal and accounting systems. Securities may be more difficult to sell at an acceptable price and may be more volatile than securities in countries with more mature markets. The value of developing or emerging market currencies may fluctuate more than the currencies of countries with more mature markets. Investments in developing or emerging market countries may be subject to greater risks of government restrictions, including confiscatory taxation, expropriation or nationalization of a company's assets, restrictions on foreign ownership of local companies and restrictions on withdrawing assets from the country. Investments in securities of issuers in developing or emerging market countries may be considered speculative.

Main Risks of Small- and Mid-Sized Companies. The stock prices of small- and mid-sized companies may be more volatile and their securities may be more difficult to sell than those of larger companies. They may not have established markets, may have fewer customers and product lines, may have unseasoned management or less management depth and may have more limited access to financial resources. Smaller companies may not pay dividends or provide capital gains for some time, if at all.

Main Risks of Derivative Investments. Derivatives may be volatile and may involve significant risks. The underlying security or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund's initial investment. The Fund may also lose money on a derivative investment if the issuer or counterparty fails to pay the amount due. Certain derivative investments may be illiquid, making it difficult to close out an unfavorable position. Derivative transactions may require the payment of premiums and can increase portfolio turnover. As a result of these risks, the Fund could realize little or no income or lose money from its investment, or a hedge might be unsuccessful.

Risks of Non-Diversification. The Fund is classified as a "non-diversified" fund under the Investment Company Act of 1940. Accordingly, the Fund may invest a greater portion of its assets in the securities of a single issuer than if it were a "diversified" fund. To the extent that the Fund invests a higher percentage of its assets in the securities of a single issuer, the Fund is more subject to the risks associated with and developments affecting that issuer than a fund that invests more widely.

Who Is the Fund Designed For? The Fund is designed primarily for investors seeking total return over the long term, from a fund that invests mainly in foreign debt securities. Those investors should be willing to assume the risks of short-term share price fluctuations of a fund that focuses on debt investments in foreign securities, including those in emerging markets. The Fund is intended to be a long-term investment, not a short-term trading vehicle. Because the Fund's income will fluctuate, it is not designed for investors needing an assured level of current income. The Fund is not a complete investment program. You should carefully consider your own investment goals and risk tolerance before investing in the Fund.

An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
