Problem 1 Consider the borrowing costs faced by the following three companies: A B C Fixed 3.0% 3.9% 4.8% -> Floating LIBOR + 0.2% LIBOR + 0.7% LIBOR + 1.4% -> Assume that if any two companies enter the swap transaction, they split the possible savings equally a) Company B and company C want to engage in the swap transaction. Find the range for the swap rate within which both companies would benefit from the swap? 1 b)-Suppose company B wants to borrow fixed rate funds. Is it possible for B to reduce its cost of borrowing below 3.9%, and if so, what is the lowest possible cost it could achieve? I c) Suppose company B wants to borrow floating rate funds. Is it possible for B to reduce its cost of borrowing below LIBOR +0.7%, and if so, what is the lowest possible cost it could achieve?
