Answer:
The annual YTM will be = 0.07518796992 or 7.518796992% rounded off to 7.52%
Explanation:
The yield to maturity or YTM is the yield or return that an investor can earn on the bond if the bond is purchased today and is held till the bond matures. The formula to calculate the Yield to maturity of a bond is as follows,
YTM = [ ( C + (F - P / n)) / (F + P / 2) ]
Where,
C is the coupon payment
F is the Face value of the bond
P is the current value of the bond
n is the number of years to maturity
Lets assume the par value is 1000.
Current value = 1000 * 109% = 1090
Coupon payment = 1000 * 0.085 * 6/12 = 42.5
Number of periods remaining till maturity = 14 * 2 = 28
semi annual YTM = [ (42.5 + (1000 - 1090 / 28)) / (1000 + 1090 / 2)
semi annual YTM = 0.03759398496 or 3.759398496% rounded off to 3.76%
The annual YTM will be = 0.03759398496 * 2 = 0.07518796992 or 7.518796992% rounded off to 7.52%
