Kindly include step bu step explanation

Using finance yahoo, based upon CAT's online annual financial statements, compute CAT's EVA and ROIC of the most recent calendar year (assuming CAT's WACC input is given as 10%). Do CAT's EVA and ROIC look good that year?

Additional information:

1) When computing EVA & ROIC, you need to know the WACC amount as an input. Here we assume/pretend that WACC is given as 10% per year (hypothetical guessing only, not for real).

2) When computing FCF, you need the actual annual tax rate as an input. You can look at the firm's annual income statement, and then estimate the applicable average tax rate, by comparing each year's "Tax Provision" against "Pretax Income".

3) When computing FCF, you need to calculate the operating capital (both current and non-current) of each year and then compare for the increase in OC year-by-year. What kinds of long-term (i.e., non-current, fixed) assets are "operating" related?
