Answer:
The firm after tax cost of equity would be 13.2%
Explanation:
The computation of the firm after tax cost of equity capital is shown below
As we know that
Required rate of return = Risk free rate of return + Beta × (market rate of return - risk free rate of return)
= 8% + 1.3 × (12% - 8%)
= 8% + 1.3 × 4%
= 8% + 5.2%
= 13.2%
Since the marginal tax rate is 0%
So, the firm after tax cost of equity would be 13.2%
