Some types of bonds may also have an “effective maturity” that is shorter than the stated maturity due to prepayment or call provisions. Debt obligations without prepayment or call provisions generally have an effective maturity equal to their expected maturity. Dollar-weighted average effective maturity is calculated by averaging the effective maturity of bonds held by the Fund with each effective maturity “weighted” according to the percentage of net assets that it represents.
