QUESTION 3 A CMO has been issued with 3 tranches and a residual. At origination: - Tranche A investors own $8927 of principal with a coupon rate of 3.50%. - Tranche B investors own $2197 of principal with a coupon rate of 3.70%. - Tranche Z investors own $5350 of principal with a coupon rate of 4.50%. - The residual carries $1 thousand of principal and receives all residual payments. Mortgages backing the security issued are fully amortizing fixed rate with mortgage rate of 4.50% with 30 year maturities and monthly payments. Assume no servicing/guarantee fee and no prepayments. What is balance on tranche B at the end of the first month (same as the balance at beginning of the second month)? Round your answers to cents (e.g. if your answer is $56000.0444, write 56000.04). QUESTION 4 Consider a CMO with Interest Only (10) and Principal Only (PO) tranches that is backed by a pool of $15 thousand in fully amortizing mortgages. Mortgages are fixed rate at 3.3% with 10 year maturity and annual payments. Suppose that no prepayment is expected and there are no servicing fees. How much do investors in the 10 tranche receive in year 1? Round your answer to two decimal points (e.g. if your answer is $1,234,567.8901, write 1234567.89).
