Question

I am having difficulty solving this problem.

West Corp. issued 17-year bonds 2 years ago at a

coupon rate of 10.3 percent. The bonds make semiannual payments. If these bonds currently sell for 102 percent of par value, what is the YTM?

I got as an answer 5.02% but this is wrong. Can you help find what I’m missing.
