Answer:
Firm's after-tax cost of equity capital = 13.2%
Explanation:
Cost of equity:
The cost of equity is the return that an investor expects to receive from an investment in a business. It is required to persuade an investor to make a given equity investment.
There isn't any need to calculate the after-tax cost separately because in our case of equity, the cost of after-tax and pre-tax is same.
Formula:
Cost of equity = risk-free rate + beta * ( market return - risk-free rate )
where
As beta = 1.3
risk-free rate of return = 8%
Expected return on the market = 12 %
Therefore by putting the values to the formula, we get
Cost of equity = 8% + 1.3 * ( 12% - 8% )
Cost of equity = 13.2%
