Interest FRAs

Hi Mr. Moffat,

I hope you’re doing well.

I took classes from a well known teacher. The way he has taught us to calculate net return in FRAs is abit different from what I see in examiner’s answer which results in a different answer. Could you please tell me if this is the right approach or my marks will be deducted if I follow this.

Question reference. Awan co. (Dec 13)

Int inc by 0.9
Actual return $766400 (same as examiner)
Gain due to FRA $4800 [=(((4.82-4.79)/100)/12)*4*48000000] different from examiner
Net Return $771200

The way he has calculated gain due to FRA is FRA rate (4.82) less LIBOR (4.09) less 20 basis points (mentioned in question) + 0.9

Thank you
