The fund's investments in bonds must be rated investment grade (i.e., Baa/BBB or higher) at the time of purchase or, if unrated, deemed of comparable quality by the fund's sub-adviser. Investments in bonds may include government securities, corporate bonds and municipal securities. Generally, the fund's average effective portfolio maturity will be between 3 and 10 years and the average effective duration of the fund's portfolio will be between 2.5 and 5.5 years. Because of events affecting the bond markets and interest rate changes, the maturity and duration of the portfolio might not meet the foregoing targets at all times. The fund may invest in individual bonds of any maturity or duration. A bond's maturity is the length of time until the principal must be fully repaid with interest. Average effective portfolio maturity is an average of the maturities of bonds held by the fund directly and the bonds underlying derivative instruments entered into by the fund, if any, adjusted to reflect provisions or market conditions that may cause a bond's principal to be repaid earlier than at its stated maturity. Duration is an indication of an investment's "interest rate risk," or how sensitive a bond or the fund's portfolio may be to changes in interest rates. The fund typically sells a security when the fund's sub-adviser believes that there has been a negative change in the credit quality of the issuer or has identified a more attractive opportunity or when the sub-adviser seeks to manage the fund's duration or tax position or to provide liquidity to meet shareholder redemptions.
