Consider a sequential pay CMO that is backed by 60 mortgages with average balance of $100,000 each. The mortgages have monthly payments with WAM = 15 years and WAC = 5%. There is a servicing fee of 0.6% and prepayment is according to 100% PSA. There are three tranches in this CMO: Tranch A issued for $1,500,000, tranche B issued for $3,000,000, and a Z-bond issued for $1,500,000. How much cash flow do investors in tranche A receive in the first month? Consider the same CMO as in Question 16 and suppose that in month 10, the beginning balance on tranche A is $1,200,596, the beginning balance on tranche B is $3,000,000 and the beginning balance on Z is $1,550,232. How much cash flow do investors in tranche A receive in month 10?
