A CMO has been issued with 3 tranches and a residual. At origination: - Tranche A investors own $50 million of principal with a coupon rate of 3.50%. - Tranche B investors own $2 million of principal with a coupon rate of 3.70%. - Tranche Z investors own $9 million of principal with a coupon rate of 4.50%. The residual carries $1 million 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.
