The Barclays U.S. Aggregate Bond Index, an unmanaged, market value weighted index of fixed income securities, is not available for direct investment. Unlike a mutual fund, the performance of an index assumes no taxes, transaction costs, management fees or other expenses.
An investment in the Fund is subject to interest rate risk, which is the possibility that a Fund's yield will decline due to falling interest rates and the potential for bond prices to fall as interest rates rise. High yielding, non investment grade bonds present a greater risk of loss to principal and interest than investment grade securities. The value of debt securities may be affected by the ability of issuers to make principal and interest payments and even the possibility that the issuer will default completely. Although U.S. government securities are considered to be among the safest investments, they are not guaranteed against price movements due to changing interest rates. The Fund may invest a portion of its assets in derivatives. Derivative instruments include options, futures and options on futures. A small investment in derivatives could have a potentially large impact on the Fund’s performance. The Fund may be unable to terminate or sell a derivatives position. Derivative counterparties may suffer financial difficulties and may not fulfill their contractual obligations.
