Objective/Focus:

Asset Class:

Bond

Style:

High Credit Quality, Limited Interest Rate Sensitivity

Return of principal is not guaranteed. Bonds and other debt obligations are affected by changes in interest rates, inflation risk and the creditworthiness of their issuers. When interest rates rise, bond prices fall. With a fixed income fund, when interest rates rise, the value of the fund's existing bonds drop, which could negatively affect overall fund performance.

In contrast to owning individual bonds, there are ongoing fees and expenses associated with owning shares of bond funds. High yield bonds generally have greater price swings and higher default risks than investment grade bonds.

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
