Answer:
5.96%
6.00%
Explanation:
The yield to maturity can be computed using the rate formula in excel as shown below:
=rate(nper,pmt,-pv,fv)
nper is the number of annual interest payments of 8 years
pmt is the annual interest payment=$1000*10%=$100
pv is the current price of $1,251.22
fv is the face value of $1,000
=rate(8,100,-1251.22,1000)=5.96%
Semiannual coupon:
nper is the number of semiannual interest payments i.e 8*2=16
pmt is the semiannual interest payment=$1000*10%*6/12=$50
pv is the current price of $1,251.22
fv is the face value of $1,000
=rate(16,50,-1251.22,1000)=3.00%
semiannual yield to maturity is 3.00% while annual yield is 3.00% *2=6.00%
