Prepayment Speed

Definition

Prepayment Speed. The rate at which the pool is paying down.

Issues and Challenges

This is a model. Includes other factors such as homogeniety. Earlier notes: Same as Payment. Curtailment. Paydown is normally scheduled payments of the mortgage. Prepayment is when someone pays off the mortgage early I may send in 1500 when my monthly amount is 1000 a month. So the 500 is a prepayment. Scheduled principal payment. More notes 25 nov: Also factor in changes to the pool constituents where this is allowed for that kind of MBS. So we make estimates of how face value will will change. face value won't change but the underlying value of the Pf changes, so eg. the current mortgage factor. Model update note June 2010: Detailed types of "Prepayment Speed" analytic received from thomson Reuters, now modeled as sub types of this term. So term origin is PSA by extension, since this is the common super class of 3 specific prepayment speed analytic types defined by PSA. PSA stands for Public Securities Association. Type: PSA gives this as numeric, however definitions imply percentage, so defined as dated percentage for now. Many data models use numbers which are interpreted later as percentages so this may be the case here.
