4. Assume that the formula for the coupon rates of a floater and an inverse floater are: Floater coupon rate: reference rate + 2.15% Inverse floater coupon rate: 12.5% - reference rate Suppose the $100 million of the bond is used as collateral to create a floater with par value of $50 million and an inverse floater with a par value of $50 million, answer the following questions: (3 points) (1) What is the coupon rate of the fixed rate collateral for these two floating rate bonds? (2) Suppose the floor for the inverse floater is 1.25%. What would be the cap of the floater? 4.
