Investments in the Funds carry risks, including possible loss of principal. Investing outside the United States, especially in emerging markets, entails special risks, such as currency fluctuations, illiquidity, and volatility. Investments in small capitalization companies may increase the risk of greater price fluctuations. Funds investing in bonds have the same interest rate, inflation, and credit risks that are associated with the underlying bonds. The principal value of bonds will fluctuate relative to changes in interest rates, decreasing when interest rates rise. This effect is more pronounced for longer-term bonds. Unlike bonds, bond funds have ongoing fees and expenses. Funds invested in mortgage backed securities may bear additional risk. Investments in lower rated and unrated bonds may be more sensitive to default, downgrades, and market volatility; these investments may also be less liquid than higher rated bonds. Investments in derivatives are subject to the risks associated with the securities or other assets underlying the pool of securities, including illiquidity and difficulty in valuation. Investments in the Funds are not FDIC insured, nor are they deposits of or guaranteed by a bank or any other entity.
Before investing, carefully consider the Fund’s investment goals, risks, charges, and expenses. For a prospectus containing this and other information, contact your financial advisor or visit our literature library. Read it carefully before investing.
