Final answer:
The unlevered cost of equity capital for CCI is closest to 15.19%.
Step-by-step explanation:
The unlevered cost of equity capital can be calculated using the formula:
CoE = WACC - (D/E) * (Cost of Debt) * (1 - Tax Rate)
Given that CCI has a D/E ratio of 1.5, WACC of 12%, cost of debt of 12%, and a corporate tax rate of 35%, we can substitute these values into the formula:
CoE = 12% - (1.5) * (12%) * (1 - 0.35) = 12% - 18% = -6%
Since a negative cost of equity doesn't make sense, we can conclude that the closest option is a. 15.19%.
