Targeted Amortization Class - TAC

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. 



|||The TAC is essentially a bond under a collateralized mortgage obligation (CMO). Under a TAC, the principal is paid on a predetermined schedule. Any prepayment that occurs is amortized in order to maintain the schedule. TACs are inferior to PACs because they only provide one-sided prepayment protection.
