Final answer:
To calculate the WACC, you first need to find the cost of debt and the cost of equity. The cost of debt can be calculated using the yield to maturity of the company's bonds, while the cost of equity can be calculated using the CAPM. Once you have these values, you can calculate the WACC using the target capital structure.
Step-by-step explanation:
To calculate the Weighted Average Cost of Capital (WACC), we need to consider the cost of debt and the cost of equity. The cost of debt is the yield to maturity of the company's bonds. In this case, the bond has a par value of $1,000, an annual coupon rate of 8%, a maturity of 20 years, and a market price of $1,050. The yield to maturity can be calculated using the formula:
YTM = (Annual Coupon + ((Par Value - Market Price) / Years to Maturity)) / ((Par Value + Market Price) / 2)
Plugging in the values, the YTM is (80 + ((1,000 - 1,050) / 20)) / ((1,000 + 1,050) / 2) = 8.57%. Since the firm's tax rate is 40%, the after-tax cost of debt is 8.57% * (1 - 0.40) = 5.14%.
The cost of equity can be calculated using the Capital Asset Pricing Model (CAPM). The CAPM formula is:
Cost of Equity = Risk-Free Rate + Beta * Market Risk Premium
Plugging in the values, the cost of equity is 4.50% + 1.20 * 5.50% = 11.50%.
Finally, to calculate the WACC, we use the formula:
WACC = (Weight of Debt * Cost of Debt) + (Weight of Equity * Cost of Equity)
Given the target capital structure of 35% debt and 65% equity, the WACC is (0.35 * 5.14%) + (0.65 * 11.50%) = 7.91%.
