Vputable = Vnonputable + Vput
Rearranging, the value of the put can be stated as:
Vput = Vputable − Vnonputable
Vputable was computed to be $105.173 in the previous question, and Vnonputable was determined to be $104.755 in the question prior to that. So the value of the embedded put option for the bond under analysis is:
$105.173 − 104.755 = $0.418
