Imagine a firm with the first year FCF of $22M. You expect the FCFs to grow 2.50% per year indefinitely. This firm's capital structure is as follows: Debt represents 54% of the total capital. Equity represents 46% of the total capital and the cost of equity is 9.60%. The corporate tax rate is 20%. If the unlevered firm value (VU) is $500M, what is the (pre-tax) cost of debt? 5.40% 4.60% 5.75% 5.10% 4.85%
