Suppose Star and Moon agreed to the five - year, 3.75 % /LIBOR generic swap with a NP of $500 million described in Problem 2 . However, suppose one year after agreeing to the swap, the Moon Company decides to close their swap when the fixed rate on new par value four - year swaps were at 4 % . How much would a swap dealer have to pay or charged to assume Moon’s existing floating- payer’s position on the 3.75 % /LIBOR generic swap with four years left to maturity and notional principal of $500 million?
