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. 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.
