The average life, also referred to as the âweighted average lifeâ or âweighted average maturityâ or âWAM,â is a reflection of the rapidity with which the principal of an issue is expected to be paid.
The weighted average maturity (WAM) of a portfolio is the average time, in years, it takes for the bonds in a bond fund or portfolio to mature. WAM is calculated by weighting each bond's time to maturity by the size of the holding. Portfolios with longer WAMs are generally more sensitive to changes in interest rates.
