Answer:
12.39%
Step-by-step explanation:
in order to determine the realized rate of return we need to calculate the yield to call:
YTC formula = {coupon + [(call price - market price)/n]} / [(call price + market price)/2]
YTC = {$120 + [($1,080 - $1,000)/9]} / [($1,080 + $1,000)/2]
YTC = $128.89 / $1,040 = 0.1239 = 12.39%
In this case, the investor's realized rate of return was actually higher than the expected yield to maturity (YTM = 12% since bonds were sold at face value).
