TAC Tranche - Targeted Amortization Class
Targeted amortization class tranche. A TAC tranche uses a mechanism similar to a sinking fund to determine a fixed principal payment schedule based on an assumed prepayment rate. The effect of prepayment variability that is removed from the TAC tranche is A type of credit derivative that is similar to a planned amortization class (PAC) in that it protects investors from prepayment; however, it is structured differently than a PAC. TACs protect investors from a rise in the prepayment rate or a fall in interest rates. They do not protect from a fall in the prepayment rate like PACs.
