Answer:
13.35%
Explanation:
The computation of the after-tax weighted average cost of capital is shown below:
Weighted average cost of capital is
= Weight of equity × Cost of equity + weight of debt × after cost of debt
where,
Weight of equity = $120,000,000 ÷ $200,000,000 = 0.60
Cost of equity = 17%
Weight of debt = $80,000,000 ÷ $200,000,000 = 0.40
And, after cost of debt is come from applying the rate formula which is shown in the attached spreadsheet i.e 12.13%
So after tax it is
= 12.13% × (1 - 0.35)
= 12.13% × 0.65
= 7.8845%
So, the WACC is
= 0.60 × 17% + 0.40 × 7.8845%
= 10.2% + 3.1538%
= 13.35%
