Anyone know what the supporting calculation is? I haven’t seen that before. The fact pattern states the duration of a fixed bond is 75% of its maturity. So based on that, I chose Swap 1 with the following calculations: Duration of fixed side = .75*-4 = -3 Duration of floating = 0.5*.5 = .25 Net duration = -2.75 Obviously this isn’t the proper way, but what is this 1/2/2 business?
Okay, so 1/2/2 refers to the floating side, which is 1/2 of the 2 year swap duration. My question is, why are they taking 1/2 of the swap term? Shouldn’t it be 1/2 of the settlement dates?
floating semi ann ,5/2=.25 quaterly .25/2=.125

if you have quarterly it can range from 0 to .25, so the average would be .125 if you have semi-annual it can range from 0 to .50, so the average would be .25 if you have monthly it can range from 0 to 0.0833, so the average would be .0417
