Final answer:
The levered cost of equity for Alpha Co. is calculated using the Modigliani-Miller proposition II without taxes, resulting in 14.7%, which is option C from the multiple-choice options.
Step-by-step explanation:
The question asks us to calculate Alpha Company's levered cost of equity, given its debt-equity ratio, pretax cost of debt, and unlevered cost of equity while ignoring taxes. To find this, we can use the Modigliani-Miller proposition II without taxes (since we are ignoring taxes in this scenario). The formula for the cost of equity is:
Re = Ru + (Ru - Rd) * (D/E)
Where Re is the levered cost of equity, Ru is the unlevered cost of equity, Rd is the pretax cost of debt, and D/E is the debt-equity ratio. Plugging in the values we have:
Re = 12% + (12% - 7.5%) * 0.6
Re = 12% + 4.5% * 0.6
Re = 12% + 2.7%
Re = 14.7%
Thus, the levered cost of equity for Alpha Co. is 14.7%, which corresponds to option C.
