Answer:
No. Because his calculation fails to include both the working capital and capital expenditures necessary to sustain the company’s operations
Explanation:
Free Cash Flow (FCF) can simply be defined as the net flow for a company after taking account of cash operating expenses, taxes (some textbooks may omit this), and investments in working capital and capital expenditure required to sustain continuous business operations.
As such, an appropriate formula for FCF would be:
sales revenue - cash operating cost (this will exclude depreciation) - operating taxes - investment in working capital - capital expenditure.
Tyler's formula did not include investment in working capital and capital expenditure, thus making it incomplete.
