Two parties wish to enter into a direct swap to take advantage of the other partys comparative advantage.

Party A wishes to borrow at a fixed rate, but if it went into the market, it could borrow fixed at 13.25%. However, if it borrowed floating, it could borrow at BBSW + 3.95%

Party B wishes to borrow floating, and if it did so, it could borrow at BBSW + 2.15%. However, if it borrowed fixed, it could borrow at 8.85%

Describe the transaction which will maximise the benefit for both parties
