Answer:
9.05%
Explanation:
Calculation to determine the firm's marginal cost of capital at a total investment level of $269 million
Capital Budget = $269 million
To be financed through Equity = 269 million*130/(310+60+130)
To be financed through Equity = 269 million*130/500
To be financed through Equity = 69.9 million
Available from retained earnings = $97 million
Hence, No external equity will be required
Now let calculate the the firm's marginal cost of capital using this formula
WACC = Cost of debt*Weight of Debt + Cost of Preferred Stock*Weight of Preferred Stock + Cost of Equity*Weight of Equity
Let plug in the formula
WACC= 9%(1-45%)*310/500 + 13%*60/500 + 22%*130/500
WACC= 9%(55%)*310/500 + 13%*60/500 + 17%*130/500
WACC=.03069+.0156+.0442
WACC=0.09049*100
WACC=9.049%
WACC=9.05%(Appropriately)
Therefore the firm's marginal cost of capital at a total investment level of $269 million is 9.05%
