QUESTION 7 Same as Question 6, consider a sequential pay CMO that is backed by 100 mortgages with average balance of $150,000 each. The mortgages have monthly payments with WAM = 30years and WAC = 6%. There is a servicing fee of 0.4% and prepayment is according to 150% PSA. Tranche A holds $6,000,000 of the mortgage pool principal at origination, tranche B holds $3,000,000 and tranche 2 holds. The rest of the pool principal is held by the SPV as a residual. The SPV has set a pass-through rate (coupon rate net of the servicer/guarantee fee) of 4% for Tranche A, 4.5% for Tranche B and 5% for Tranche Z. What is the cash flow to the residual tranche in month 1? QUESTION 8 Consider a sequential pay CMO that is backed by 125 mortgages with average balance of $100,000 each. The mortgages have monthly payments with WAM = 15 years and WAC =7%. There is a servicing fee of 0.3% and prepayment is according to 200% PSA. Tranche A holds $7,000,000 of the mortgage pool principal at origination, tranche B holds $3,000,000 and tranche 2 holds $2,000,000. The rest of the pool principal is held by the SPV as a residual. The SPV has set a pass-through rate (coupon rate net of the servicer/guarantee fee) of 5.5% for Tranche A, 5.75% for Tranche A and 6.5% for Tranche A. At the beginning of month 7, the overall mortgage pool balance has 12,173,35258 of principal remaining. Of that overall principal at the beginning of month 7, Tranche A holds 6,607,465.99, Tranche B holds 3,000,000 and Tranche Z holds
