CFA 2009 Exam

Hi all, May I ask you a quick question? For 2009 exam answer key p. 49, do you know why under “supporting calculation”, swap 1 receive floating is 1/2/2 or swap 2 receive floating is 1/4/2? Also, for the previous page, Part A iii Roll Return, I do not remember seeing any of that convenience yeild/interest rate relationship in Schewser. Is that in the original reading? Many thanks.

welcome rhoda… floating rate coupon bond has duration of 0.5 of coupon frequency

Thanks Pimpineasy for your quick reply! so always 1/ frequency of coupons in a year /2 for floating rate bond’s duration?
