How these figures are calculated

Annual columns are full-year amounts from the annual report (Form 10-K, 20-F, or 40-F). If a company restates a year, the latest filed number is shown. USD in millions, except per-share amounts and ratios. Capital expenditures, debt repaid, dividends, and buybacks are positive amounts. Investing and financing cash flow keep the filing sign, so an outflow is negative. Free cash flow is operating cash flow minus capital expenditures. The first column is the trailing twelve months through the latest quarter. Returned to shareholders is dividends plus buybacks. Free cash flow margin, capital expenditures, and stock-based compensation are divided by revenue. Cash conversion is operating cash flow divided by net income. More on our methodology.
