Final answer:
BCCI's cost of equity capital is 76%, calculated using the Capital Asset Pricing Model (CAPM). Its WACC is found to be 54.685% when incorporating the company's capital structure and tax rate.
Step-by-step explanation:
WACC and Cost of Equity Calculation
To calculate BCCI's cost of equity capital, we can use the Capital Asset Pricing Model (CAPM). CAPM formula is given by:
Cost of Equity = Risk-Free Rate + (Beta × Market Risk Premium)
Substituting the given values, we get:
Cost of Equity = 4% + (9 × 8%) = 4% + 72% = 76%
To calculate the Weighted Average Cost of Capital (WACC), we use the formula:
WACC = (E/V × Cost of Equity) + ((D/V × Cost of Debt) × (1 - Tax Rate))
Where E is the market value of the equity, D is the market value of the debt, V is the total market value of the company (E + D), and Tax Rate is the corporate tax rate.
Substituting the values for BCCI, we have:
WACC = (0.70 × 76%) + (0.30 × 5% × (1 - 0.21))
WACC = 53.2% + (1.485%) = 54.685%
