Final answer:
The equity of the firm can be calculated by subtracting the firm's debt from its total enterprise value. In this case, the equity is $102 million. The firm would invest $183 million in order to capture the 5% return to society.
Step-by-step explanation:
The value of the firm's equity can be calculated by subtracting the firm's debt from its total enterprise value. Given that the firm has an EBIT of $120 million, and the tax rate is 25%, the after-tax income would be ($120 million * (1-0.25)) = $90 million. Using a constant growth formula, we can calculate the enterprise value as follows:
Enterprise Value = EBIT * (1 - Tax Rate) / Cost of Capital
Since the EBIT is $90 million and the cost of capital is 9%, the enterprise value is $102 million. Therefore, the firm's equity is equal to the enterprise value minus the debt, which is $102 million.
If the interest rate is 9%, the cost of financial capital, and the firm can capture the 5% return to society, the firm would invest as if its effective rate of return is 4%. To calculate the investment amount using the formula:
Investment Amount = Return on Capital / Cost of Capital = $5 million / 0.04 = $125 million.
Therefore, the firm would invest $183 million in order to capture the 5% return to society.
