Party A wishes to borrow at a fixed rate, but if it went into the market, it could borrow fixed at 12.95%. However, if it borrowed floating, it could borrow at BBSW + 2.75%

Party B wishes to borrow floating, and if it did so, it could borrow at BBSW + 1.35%. However, if it borrowed fixed, it could borrow at 9.55%

The investment bank charges 0.30% on each leg of the swap
