This question is from the recent South African exam (course similar to SP5):
Happy Credit (HC) extends 3-, 4- and 5-year personal loans with the variable interest rate being linked to the prime rate, and capital being repaid over the loan term. HC funds its operations by issuing 3-year Floating Rate Notes (FRNs) at par, paying the 3-month Johannesburg Interbank Average Rate (JIBAR) plus 1% p.a.
At present the annual, continuously compounding JIBAR 3-month rate is 9% and the 6-month rate, 10%.
Calculate the value of a FRN that was issued by HC, with six months outstanding, on a principle of R10 million.
I don't quite understand the memo which reads:

Why is there a -1 part to the equation?
This seems like a very simple question, but am struggling to understand the concept.
