Hi mastvikas,
Tuckman tends to use semi-annual compound frequency
(and if compound frequency is not explicitly given, the fact that coupons pay semi-annually is our best evidence that compound frequency "follows suit" with semi-annual
e.g., if we are not told comp frequency, and the coupon payments are annual, then best assumption is annual compound frequency). So in this case,
287.5/(1+5.75%/2)^(0.5*2) = 287.5/1.028750 = $279.4654. Thanks,
