Answer:
10.72%
Step-by-step explanation:
Firstly, we need to calculate cost of equity using capital pricing model (CAPM):
Cost of equity = Risk-free rate + Beta x Market risk premium
= 4% + 1.7 x 7% = 15.9%
Note: Treasury bill rate is used as a proxy for risk-free rate in this case.
Then, we will calculate weighted average cost of capital (WACC) as below:
Weighted average cost of capital = Debt weight in capital structure x Pre-tax cost of debt x (1 - tax rate) + Equity weight in capital structure x Cost of equity
= [780/(780 + 780)] x 7% x (1 - 21%) + [780/(780 + 780)] x 15.9%
= 10.72%
Note: Yield to maturity on long-term debt is used as a proxy for pre-tax cost of debt in this case. Weights used in WACC calculation have to be based on market value.
So, the company WACC is 10.72%.
