Figures are rounded to the precision shown, so a column can differ slightly from its own total.

Source of the numbers: structured XBRL data from the filing (10-K). The diagram is generated automatically and checked against EDGAR before release. The fourth quarter has no column of its own in an annual report, so it is the full year minus the first nine months. How we calculate it → About and methodology.
