Issue Date Principal Balance

The principal balance of each mortgage in an MBS pool after crediting the principal portion of any monthly payments due on or before the issue date for the related MBS (whether or not it was actually collected) and after crediting any unscheduled partial payment or other recovery of principal received on or before the issue date (as long as it was not accompanied by payment of an interest amount that represented scheduled interest due for the month after the payment was made).
