This part of the reading is really annoying me as I can’t get my head around it - Managing duration of FI portfolio using Swaps
How does one arrive at duration of float side payments? eg. EOC Q2
  • Duration of 4 yr pay float and rec fixed swap with quarterly payments is Float - 0.125, Fixed - 0.75x4
  • Duration of 3 yr Swap and semiannual payments - float - 0.25, Fixed - 0.75x3
I can’t seem to get the equivalent BB problem and some of the preceeding text too. Am I missing something obvious here? Can someone help here?
Appreciate it.
 
the duration a of floating swap payment is the amount of time between reset dates. In the case of the quarterly pay swap, the period between reset dates is a 3 months (i.e. 0.25). Covention is to use half the period between reset dates, or 0.125.
In the case of the semi-annual pay swap, the duration is 0.50. So, half the period between reset dates would be 0.25.

Your conclusions are correct, but your explanation is off: the floating rate duration is half the time between resets, and you use that amount: 0.25 years for semiannual pay swaps, 0.125 years for quarterly pay swaps, and so on.
 
SWAP duration:
Variable leg = half of resetting period, ie 0.125 for quarterly reset, 0.25 for semiannual reset
Fixed leg = assumed to be 0.75 x (# of years)
(+) sign for receiving, (-) sign for paying
so if receive fix & pay variable = higher duration
