• The weighted average remaining term (WART) is a measure of the average time to maturity of a fixed income portfolio.

  • WART is also known as maturity weighted average or WAM.
  • It is often used for mortgage-backed securities (MBS) and other asset-backed securities (ABS), although it can be applied to any fixed income portfolio.
  • Some investors may prefer to have access to investments with a specific repayment profile, which makes WART a useful tool for comparing alternative investments.
  • WART is particularly important in assessing the portfolio’s interest rate and prepayment risk.
