Question:
Consider the following structuring problem. The asset pool exhibits the following properties: WAC = 14%; WAM = 60 months; and an expected loss to default of 5%, given the class/type of loans. There is a servicing fee of 1% and there is a 1% reserve (developed internal to the deal with excess cash flow). This asset pool and structure supports a two class liability: Class A with a coupon of 7% and a subordinate class B with a coupon of 10%. We assume a pricing speed of 1.5 ABS where the average life is 1.98% and have tested for a stress case of 2.5 ABS where the average life is 1.64. Due to the narrow variance of the APRs on the loans, we ignore adverse prepayment effects as immaterial. Use the S&P scale for ratings where an AAA rating has a coverage ratio of at least 5X; AA is 4X; A is 3X; BBB is 1.5 - 2X; with anything less than 1.5X is sub- investment grade.(35 pts. As below)

- Hint:Let a = % of deal in Class A and (1-a) be the % of deal in Class B; then WAI = a (7) + (1-a) 10 = 10 - 3a and carry this relation through to see what value of "a" works.
