Assume AAA wants to borrow $1,000,000 at fixed rate and BBB wants to borrow $1,000,000 at floating rate. AAA can borrow either at LIBOR+1% or at 5%, BBB can borrow either at LIBOR+3% or at 6.3%. Assume AAA and BBB enter into a mutually beneficial swap in which they exchange LIBOR interest rate payments for a fixed x% interest rate payments. Find the maximum and minimum values of x.
