Suppose that IBM would like to borrow fixed-rate yen, whereas Korea Development Bank (KDB) would like to borrow floating-rate dollars. IBM can borrow fixed-rate yen at 4.5% or floating-rate dollars at LIBOR + 0.25%. KDB can borrow fixed-rate yen at 4.9% or floating-rate dollars at LIBOR + 0.8%.

a. What is the range of possible cost savings that IBM can realize through an interest rate/currency swap with KDB?

b. Assuming a notional principal equivalent to $125 million and a current exchange rate of ¥105/$, what do these possible cost savings translate into in yen terms?

c. Redo parts a and b assuming that the parties use Bank of America, which charges a fee of 8 basis points to arrange the swap.
