Return of principal is not guaranteed. Bond funds have the same interest rate, inflation and credit risks that are associated with the underlying bonds owned by the Fund. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund's existing bonds drops, which could negatively affect overall fund performance

Investors should be aware of the risks of investments in foreign securities, particularly investments in securities of companies in developing nations. These include the risks of currency fluctuation, of political and economic instability and of less well-developed government supervision and regulation of business and industry practices, as well as differences in accounting standards.
