Answer: D) Projects A and C
Explanation:
The projects to be taken should have a higher IRR than the company's Weighted Average Cost of Capital.
Cost of Equity
= Risk free rate + beta( market return - risk free rate)
= 4% + 1.7 (12% - 4%)
= 17.6%
After tax cost of debt
= Yield ( 1 - tax rate)
= 10% * ( 1 - 30%)
= 7%
WACC = (Weight of debt * after tax cost of debt) + (weight of equity * cost of equity)
= (0.6 * 7% ) + ( 0.4 * 17.6%)
= 4.2% + 7.04%
= 11.24%
Projects A and C both have IRR higher than the company's WACC and so should be accepted.
