As the company reported it, from the “REVENUE RECOGNITION - Schedule of Disaggregation of Revenue (Details)” note of its latest 10-K. Every figure here has been checked against the total revenue the same filing reported. Regions are the filer's own and are not mapped onto a standard list — one company's “Americas” and another's “United States” are different areas, and making them look comparable would mean making at least one of them wrong. Slices under 1% are folded into “Other”.
