Weighted Average Remaining Term (WART)

Weighted average remaining term (WART) is a calculation used to compare the time to maturity of asset-backed securities (ABS), most commonly mortgages. A portfolio containing a large number of long-term securities will tend to have a higher WART than another pool with short-term maturities, depending on the relative principals of those securities. The weighted average remaining term is also known as weighted average maturity.
