Answer:
Find the YTM on current bonds
Use financial calculator
FV= $1000
PV= $1143
N= 19*2= 38
PMT = 0.103 * 1,000 * 0.5 == 51.5
Compute I= 4.37%*2= 8.74%
If the company wants to sell the new bonds on par it should set the coupon rate as 8.74% because when ytm and coupon rate are the same the bond sells on par.
