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. Each group is a separate split of total revenue, so the groups are not added together. Share of revenue is that line divided by total revenue. The first column adds the latest year-to-date segment amount to the last fiscal year and subtracts the year-ago year-to-date amount. More on our methodology.
