Total Invested Capital =
Total Current Assets - Total Operating Liabilities (ie. Current Liabilities excluding any debt) + Total Non-Current Assets.
Where can I see the numbers?
The best way to determine how Total Invested Capital (aka. Total Operating Investment) is calculated, is to go to the Financial Statements tool in Fathom.
In the 'Balance Sheet' view, select 'Separation of Operations and Finance' as the layout. 'Total Invested Capital' will then be listed in the Balance Sheet along with 'Total Current Assets', 'Total Operating Liabilities', and 'Total Non-Current Liabilities'.
