Answer:
6.47%
Step-by-step explanation:
The computation of effective annual yield is shown below:-
Annual YTM = 6.37%
Semiannual YTM = 6.37% ÷ 2
= 3.185%
Effective Annual Yield = (1 + Semiannual YTM)^2 - 1
= (1 + 0.03185)^2 - 1
= 1.03185^2 - 1
= 1.0647 - 1
= 0.0647
or
= 6.47%
Hence, the effective annual yield is 6.47% i.e come after applying the above formula
