How can I solve this?

Able Inc. and Baker Inc. face the following borrowing costs in the fixed and floating rate markets:

?? FixedRate Market????Floating Rate Market

Baker? T + 1. 95% ???? L + 0.30%

Able ? T + 0.65%???? L 0.15%

Each firm desires the rate other than that for which it has comparative advantage.

A dealer stands ready to enter into a swap as either a fixedrate payer or floating-rate receiver (or vice versa). The dealer will pay a fixed T+1.22% against LIBOR or receive T+1.30% against LIBOR. Assume that each firm borrows in the market in which it has comparative advantage and enters into a swap agreement. Analyze the potential gains from swapping for all parties under the following headlines:

a) List all loans Able deals with. What is the effective loan rate for Able?

b) By how much is Baker better-off from the swap agreement?

c) What is the overall benefit of the three parties: Able, Baker and the Dealer?
