† The diluted share count jumps at 2021, so per-share figures either side of that column are not comparable. Usually a split, but the break lands on the restatement boundary rather than on the split date, because every column is that period’s latest filing.

Lines marked calc are worked out here from filed figures; point at one for how. Capital expenditure, dividends and buybacks are shown as money out, so negative.
