CB Solutions.Heather O'Reilly, the treasurer of CB Solutions, believes interest rates are going to rise, so she wants to swap her future floating-rate interest payments for fixed rates. Presently, she is paying per annum on $ 5 comma 200 comma 000 of debt for the next two years, with payments due semiannually. LIBOR is currently 4.008 % per annum. Spread paid over LIBOR, per annum is 2.000 %. Heather has just made an interest payment today, so the next payment is due six months from now. Heather finds that she can swap her current floating-rate payments for fixed payments of 7.006 % per annum. (CB Solutions' weighted average cost of capital is 12 %, which Heather calculates to be 6 % per 6-month period, compounded semiannually). a. If LIBOR rises at the rate of 50 basis points per 6-month period, starting tomorrow, how much does Heather save or cost her company by making this swap? b. If LIBOR falls at the rate of 25 basis points per 6-month period, starting tomorrow, how much does Heather save or cost her company by making this swap?
