Restated years: each year's figure is from the latest filing that reports it. The company later restated the year ended 2017-12-31 (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.
Older than the company's other figures. The latest Cost of Revenue is for the year ended 2019-12-31, while the company's latest annual report covers the year ended 2025-12-31. Its later filings do not report this line under the concept TickerFacts maps.
