This arrangement does not cover interest, taxes, brokerage commissions, and extraordinary expenses. The Fund has agreed to repay the Adviser for expenses reimbursed to the Fund provided that repayment does not cause the Fund's annual operating expenses to exceed the Expense Limitation.

The Adviser’s investment process is centered on analyzing macroeconomic factors across emerging market countries. These include an evaluation of interest rates, monetary and fiscal policies, expectations for inflation, trade and current account balances, budgets, political environments and other considerations. Decisions related to specific sectors of the market are driven by the Adviser’s expectations concerning U.S. and global economic cycles.• Under normal circumstances, the Fund will invest at least 80% of its net assets (including fixed income related futures, options, swaps and other instruments as well as borrowings for investment purposes) in fixed income instruments including forward foreign exchange contracts denominated in emerging market currencies. The Fund may invest in derivatives denominated in any currency and such instruments will be included under the 80% of net assets policy provided the underlying asset is a fixed income or currency instrument denominated in an emerging market currency. In defining emerging markets, the Adviser may consider, but is not bound by the classifications of the World Bank and will generally invest in countries other than the U.S., Japan, Australia, Canada, New Zealand and the developed countries in Western Europe. The Fund will provide shareholders with at least 60 days notice prior to any changes in this policy.• The Fund will invest in fixed income instruments issued by governments, supranational entities, quasi—governmental institutions and corporations that are economically tied to the emerging markets.• The Fund will be managed to have a duration of approximately plus or minus four years relative to its benchmark, which is currently the JPM Global Bond Index—Emerging Markets Global Diversified Index. As of October 31, 2010, the duration of the JPM Global Bond Index—Emerging Markets Global Diversified Index was 4.51 years.• Invests in derivatives for hedging and non-hedging purposes. Derivatives are financial instruments the value of which is derived from another security, a commodity (such as gold or oil), an index or a currency (a measure of value or rates, such as the S&P 500 Index or the prime lending rate). The Fund typically uses derivatives as a substitute for taking a position in an underlying asset and/or as part of a strategy to reduce risk, such as interest rate risk, currency risk, and price risk. The Fund expects that derivative instruments will include, but are not limited to, futures contracts, forward contracts, non-deliverable forwards, options, options on futures, swaps, interest rate warrants, and structured notes. A forward contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. Forward contracts are the primary means of hedging currency exposure. A futures contract commits the parties to a transaction at a time in the future at a price determined when the transaction is initiated and generally trade through regulated exchanges and are “marked to market” daily both of which reduce liquidity risk. A swap is an agreement between two parties to exchange certain financial instruments or components of financial instruments such as streams of interest rate payments, principal denominated in two different currencies, or virtually any payment stream as agreed to by the parties. A credit default swap is a credit derivative contract between two counterparties. The buyer makes periodic payments to the seller, and in return receives protection if an underlying financial instrument defaults. From time to time, the Fund’s investments in derivatives may be significant.

Investments in the Fund carry a certain amount of risk and the Fund cannot guarantee that it will achieve its investment objective. You may lose money by investing in the Fund. Below are the principal risks of investing in the Fund:• Diversification Risk: As a non-diversified mutual fund, the Fund may invest a greater portion of its assets in the securities of a single issuer or similar types of issuers, and, as a result, may be subject to greater fluctuations in share price due to changes in the market value of a single investment or similar types of investments.• Foreign Investment Risk: The Fund will invest in foreign securities which may lose value because of fluctuations in currency exchange rates and market liquidity, price volatility, uncertain political and legal conditions, lack of reliable financial information and other factors. Foreign securities of certain countries are subject to political instability, which may result in potential revolts and the confiscation of assets by governments. As a result, the Fund’s returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country or region. In the event of nationalization, expropriation or other confiscation or capital controls, the Fund could lose its entire investment in foreign securities. Adverse conditions in a certain region can adversely affect securities of other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region, the Fund will generally have more exposure to regional economic risks associated with foreign investments.• Emerging Market Risk: The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. Emerging markets are generally smaller, less developed, less liquid, and more volatile than developed markets, and are subject to greater social, political and economic uncertainties, higher levels of inflation and currency devaluation and settlement and operational risks, including risks related to foreign securities custody. Investments in countries of Central and Eastern Europe and former states of the Soviet Union, including Russia, are subject to greater risk of expropriation of private industry and a partial or total loss of an investment in such foreign securities.• Foreign Currency Transaction Risk: As foreign securities are usually denominated in foreign currencies, the Fund may employ strategies intended to protect the Fund’s portfolio from adverse currency fluctuations. The Fund may also employ strategies intended to increase exposure to certain currencies. Such currency transactions involve additional risks, and the Fund’s strategies, if unsuccessful, may decrease the value of the Fund.• Below Investment Grade Securities Risk: The Fund’s investments in lower quality debt securities are generally more speculative, less liquid and subject to higher incidence of default than investment grade securities.• Maturity Risk: The Fund’s investments in fixed income securities may lose value because of declines in the bond market; longer-term securities are generally more volatile. Duration takes into account the pattern of a security’s cash flow over time, including the way cash flow may be affected by prepayments and interest rate changes.• Interest Rate Risk: The Fund’s fixed income investments are subject to interest rate risk which generally causes the value of a fixed income portfolio to decrease when interest rates rise resulting in a decrease in the Fund’s net assets. Interest rate fluctuations tend to have a greater impact on fixed income-securities with longer durations.• Credit Risk: Fixed income securities are subject to credit risk, which is the risk that an issuer of a bond will be unable to repay interest and principal in a timely manner. In the event of an unanticipated default, the Fund would experience a reduction in its income and could expect a decline in the market value of the securities so affected.• Prepayment Risk: The principal amount of the mortgages underlying the Fund’s investments in mortgage-related securities may be prepaid, generally when interest rates fall, which may cause the Fund’s income to decline.• Liquidity Risk: Particular investments may be difficult to purchase or sell such as fixed-income securities which have not received any credit ratings, below investment grade securities or securities that are not widely held. The Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions, which may reduce the returns of the Fund because it may be unable to sell the illiquid securities at an advantageous time or price.• Regulatory Risk: Foreign companies may not be registered with the SEC and are generally not subject to the regulatory controls imposed on United States issuers and, as a consequence, there is generally less publically available information about foreign securities than is available about domestic securities. Foreign companies may not be subject to uniform accounting, auditing and financial reporting standards, corporate governance practices and requirements comparable to those applicable to domestic companies. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce dividend income payable to the Fund’s shareholders.• Derivatives Risk: Derivatives can be highly volatile and involve risks in addition to the risks of the underlying investment, index or rate. Derivatives involve special risks including correlation, counterparty, liquidity, operational, accounting and tax risks. Investing in derivatives also requires a specific skill set and may result in losses. Derivatives may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses. Gains or losses from derivatives can be substantially greater than the derivatives’ original cost. Derivatives can be complex instruments and can involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class the derivative is intended to provide exposure to, the derivative may not have the anticipated effect. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments.The Fund may substantially increase its use of derivatives in response to unusual market conditions that limit the Fund’s investment opportunities.• Leveraging Risk: Certain transactions may give rise to a form of leverage. Such transactions may include, among others, loans of securities, and the use of when-issued, delayed delivery or forward commitment transactions. The use of derivatives may also cause leveraging risk.• Custody/Sub-Custody Risk: The Fund may invest in markets where custodial and/or settlement systems are not fully developed. There may be very limited regulatory oversight of certain foreign banks or securities depositories that hold foreign securities and foreign currency. The laws of certain countries may limit the ability to recover such assets if a foreign bank or depository or their agents goes bankrupt and the assets of the Fund may be exposed to risk in circumstances where the custodian/sub-custodian or Adviser will have no liability. In addition, the inability of the Fund to make its intended securities purchases due to settlement issues with the custodian/sub-custodian could cause the Fund to miss attractive investment opportunities.• Redemption Risk: The Fund may need to sell its portfolio holdings in order to meet shareholder redemption requests. In selling its holdings to meet redemption requests, the Fund could experience a loss if the redemption requests are unusually large or frequent, occur in times of overall market turmoil, or declining prices for the securities sold, or when the securities the Funds wishes to or is required to sell are illiquid.An investment in the Fund is not a bank deposit or obligation of any bank and is not endorsed or guaranteed by any bank and is not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other governmental agency.You could lose money investing in the Fund.Further information about the Fund’s strategies and risks is provided in the section, Fund Strategies and Risks.falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
