Operating cash flow minus capital expenditures for the same annual period and currency, computed by TickerFacts from the filed figures. A simple proxy, not a reported figure; a year without both inputs is left out.
Restated years: each year's figure is from the latest filing that reports it. The company later restated the year ended 2018-12-31 (for example after a spin-off or a discontinued operation), while the year before it was last reported on the old basis. Changes across those points are marked n/c (not comparable), and growth rates are not computed across them.
