Answer:
After tax cost of bond= 7%
Step-by-step explanation:
In order to find the after tax cost of bond we need to know its pre tax cost of debt. The yield on a bond is its pre tax cost. In this question we are already given the yield which is 10%. This means that the pre tax cost of debt is 10%. Now in order to find the after tax cost of debt we will multiply the pre tax cost of debt by (1-tax Rate)
After tax cost of bond= 0.1*(1-0.3)= 0.07= 7%
