问题如下：
Boulder, Inc., is a US-based unleveraged firm with a constant (perpetual) cash flow of $6 million per year before taxes. The firm has a market value of $45 million and a corporate tax rate of 30%. The WACC of the unleveraged firm, prior to the debt issue, is *closest* to:
选项：
A.4.00%. B.9.33%. C.13.33%.解释：
Correct Answer: B
B is correct. The after-tax cash flows for the company are $6 million × (1 – 0.30) = $4.2 million. Since the cash flows are assumed to be perpetual, WACC is calculated as follows:
rWACC = CF(1 – t)/V = $4.2/$45 = 9.33%. Since this is an all-equity firm, the cost of equity is equal to WACC.
