Answer: the after-tax cost of debt = kd(1=T)
= 12(1-0.25)
= 12(0.75)
= 9%
The after-tax cost of debt is 9%
Explanation: The after-tax cost of debt equals cost of debt multiplied by 1-corporate tax rate. The cost of preferred stock is 13.45% ie kp = D/Po-Fc= 7.40/62-7. The after-tax cost of debt is at least 4% less than the cost of preferred stocks. The variables are defined as follows:
kd = Cost of debt
kp = Cost of preferred stocks
Po = Market value of preferred stocks
T = Corporate tax rate
Fc = Flotation cost
