The fund may also invest in U.S. dollar-denominated foreign securities of these types. Under normal circumstances, the effective duration of the funds portfolio will generally not be greater than one year. Effective duration provides a measure of a funds interest-rate sensitivity. The longer a funds duration, the more sensitive the fund is to shifts in interest rates. Under normal circumstances, the dollar-weighted average portfolio maturity of the fund is not expected to exceed four years. The Investment Manager may consider, among other factors, credit, interest rate and prepayment risks, as well as general market conditions, when deciding whether to buy or sell investments. The fund may also use derivatives, such as futures, options and credit default, total return and interest rate swap contracts, for both hedging and non-hedging purposes. Show less
