The following table shows the borrowing opportunities for two firms.
Firm A Firm B
Fixed rate 11.75 % 9.5%
Floating rate LIBOR + 0.75% LIBOR

Firm A can raise the money by issuing 5-year floating-rate notes at LIBOR + 0.75 %. However, Firm A would prefer to borrow at a fixed rate. On the other hand, Firm B is considering issuing 5-year fixed-rate Eurodollar bonds at 9.5 percent. It would make more sense for Firm B to issue floating-rate notes at LIBOR in order to finance floating-rate Eurodollar loans. Finally, the swap bank makes the following offers to both firms.

b) Firm A and B face the same financing option as the above table. However, the Swap Bank offers a new LIBOR financing as in the table below.

What are the gains for the Swap Bank and Firm B, respectively? Show your work. (90points)
