The PSA prepayment model is a prepayment scale developed by the Public Securities Association in 1985 for analyzing American mortgage-backed securities.The PSA model assumes increasing prepayment rates for the first 30 months after mortgage origination and a constant prepayment rate thereafter. [1]
Prepayment speeds can be expressed in SMM (single monthly mortality), CPR (conditional prepayment rate, which is the annually compounded SMM), or PSA (percentage of the Public Securities Association prepayment model). For mortgages at least 30 months old, 100% PSA = 6.0% CPR = 0.51% SMM, equivalent to the full prepayment of 6% of a pool's ...
Planned Amortization Class (PAC) bonds have a principal payment rate determined by two different prepayment rates, which together form a band (also called a collar). Early in the life of the CMO, the prepayment at the lower PSA will yield a lower prepayment. Later in the life, the principal in the higher PSA will have declined enough that it ...
A prepayment penalty is a fee a lender charges to discourage a borrower from paying more than their scheduled periodic payment or completely paying off their loan under the terms of the loan ...
The price of an MBS pool is influenced by prepayment speed, usually measured in units of CPR or PSA. When a mortgage refinances or the borrower prepays during the month, the prepayment measurement increases. If an investor has acquired a pool at a premium (>100), as is common for higher coupons, then they are at risk for prepayment. If the ...
The exact amount of a prepayment penalty varies from one lender to the next. In general, you can expect the fee to range from 2 percent to 5 percent of your loan. In some cases, the fee the lender ...
Prepayment uncertainty is an important concern with fully amortizing ABS. The possible rate of prepayment varies widely with the type of underlying asset pool, so many prepayment models have been developed to try to define common prepayment activity. The PSA prepayment model is a well-known example. [7] [9]
