How these figures are calculated
Quarterly columns are single-quarter amounts. When a 10-Q reports only a year-to-date total, as cash flow statements do, the quarter is that total minus the previous quarter's year-to-date total. The fourth quarter is the annual report's full year minus the first nine months. A column marked YTD is a year-to-date total, shown when the earlier report needed for the single quarter is missing. 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.
