Split-adjusted restates earlier share counts on today's basis. As reported shows the figures in each earnings release, which cannot be compared across a split.

Periods without a recorded treasury share count are not charted. Issued shares for those periods are listed in the table below.

Periods without a reported amount show "—". This does not necessarily mean nothing was paid or repurchased.

Buybacks are the amount spent on repurchases; treasury shares later handed out (for example as stock compensation) are not deducted, except where a company reports a net figure. See Treasury share disposals below.

The ratio uses net income attributable to owners of the parent, for the latest five years. Loss-making years are not shown. Dividends are the cash paid during the year (including the prior year-end dividend), so the ratio may differ from the one a company publishes.
