 WACC
Solution
New Cost of Equity
Currently, company has no debt, i.e., it is unlevered and we are given the unlevered cost of capital or equity (since it has no debt) as 10.6%. We need to find the Levered cost of equity, i.e., when the company gets debt in its capital.
As per MM proposition II without taxes -
Levered or New Cost of Equity = Unlevered Cost of Equity + [ (Unlevered cost of equity - cost of debt) x debt - equity ratio ]
or, New Cost of Equity = 10.6% + [ (10.6% - 7.7%) x 1 ] = 13.50%
WACC
If Debt - equity = Debt / Equity = 1 or 1 / 1
This means, weight of debt = weight of equity = 0.5
WACC = Weight of Equity x New cost of equity + Weight of debt x Cost of debt = 0.5 x 13.50% + 0.5 x 7.7% = 10.60%
