In May 2012, a bank will issue a 4/7 FRA referenced to BBSW with a guaranteed rate of 4.5% p.a.. Bank bill futures for September 2012 delivery are priced at 95.75. Assume there are no transaction costs and no spread between FRA borrowing and lending rates, and 30-day months.

ii) Demonstrate how this will be achieved and calculate the net gain (or loss) from this strategy if the 90-day bank bill rate turns out to be 6% in September 2012.
