Answer and Explanation:
The computation is shown below:
1. Free cash flow
= EBIT × (1 - tax rate) + depreciation expense - capital expenditure - change in net working capital
= $199.2 × (1 - 0.30) + $10 - $20 - ($80 - $70)
= $119.44
2. The WACC is
But before that following calculations need to be done
Cost of equity = (2 + 1 × 5.5)
= 7.50%
The cost of debt is 5%
The debt to total capital ratio is 30%
The equity to total capital ratio is (100 - 0.30) = 0.70
Tax rate is 30%
Now
WACC is
= (7.5 × 0.7 + 5 × 0.3 × (1 - 0.3))
= 6.30%
3. The firm value is
= $119.44 ÷ 0.063
= $1,895.87 million
