The process includes computer modeling and scenario testing of possible changes in market conditions. The fund's sub-adviser will use other techniques in an attempt to manage market risk and duration. 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, mortgage-related securities and municipal securities. Generally, the average effective duration of the fund's portfolio will not exceed eight years. Because of events affecting the bond markets and interest rate changes, the duration of the portfolio might not meet the foregoing target at all times. The fund may invest in individual bonds of any duration. There are no restrictions on the dollar-weighted average maturity of the fund's portfolio or on the maturities of the individual bonds the fund may purchase. A bond's maturity is the length of time until the principal must be fully repaid with interest. Dollar-weighted average maturity is an average of the stated maturities of the securities held by the fund, based on their dollar-weighted proportions in the fund. 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.
