Asset backed securities and MBSs typically contain issue terms that specify a method through which redeeming principal is shared among investors. When redemption is donepro-rata , a pool factor is useful to investors in cases of early repayment. Early repayment reduces the amount ofcollateral available for an issue, and therefore some of the outstanding principal is returned to investors as stated in the issue terms. In this case, the pool factor is used to indicate how the remaining outstanding principal is adequately securitized [Choudhry, Moorad, et al. "Capital Market Instruments: Analysis and Valuation".
