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.
A more suitable measure is the Weighted Average Life (WAL). It is the weighted average time for principal repayment, that is, the average time it takes for every dollar of principal to be repaid. The time weights are based on the principal payments, i.e., the years with more principal payments will have a higher weight.
