Answer: The cost of capital for a firm with no debt in its capital structure.
Step-by-step explanation:
Leverage in finance refers to the use of debt. Unlevered capital therefore would refer to capital that is without debt which means that an unlevered cost of capital is one with no debt in its capital structure.
Companies with such a capital structure derive their capital 100% from Equity and as such do not pay interest. This means however, that they will not benefit from the tax shields that interest payments offer.
