Which of the following best describes a stripped mortgage-backed security (MBS)? A stripped MBS is a security:

A)
 that provides no interest payments.
B)
 whose distribution of principal and interest has been altered from a pro rata distribution to an unequal distribution.
C)
 whose distribution of principal and interest has been altered from an unequal distribution to a pro rata distribution.

With a passthrough security, interest and principal payments generated by the underlying mortgage pool are allocated to the bondholders on a pro rata basis. This means that each passthrough certificate holder receives the same amount of interest and the same amount of principal. Stripped mortgage-backed securities differ in that principal and interest are not allocated on a pro rata basis.

Which of the following is most accurate regarding the investment characteristics of a principal-only (PO) mortgage strip?

A)
 The slower the prepayments the higher the investor's return.
B)
 The faster the prepayments the higher the investor's return.
C)
 The lower the coupon the higher the investor's return.


For a principal mortgage strip the investor does not receive interest but only the principal. Therefore, the sooner the investor receives the principal the higher the return.
