Noreen, assume the rates change linearly from 3 months to 12 months (1 year) and prorata for 2 months.. That is the 5 months forward is equally to three months plus or minus 2 months difference.
Simply put that d 3mnths is inclusive in d 1 year. So, deduct d 3mnths rate from 1 year rate. Get a 2 months pro-rated rate from d remaining 9 months & deduct 4rm d 3 months rate 2 get d 5 month forward rate.
