Splits: 2015-04-01: 2-for-1 split (effective date)

※ 2015-06: 2-for-1 split. From this period, the earnings release reports post-split share counts (this can start before the effective date).

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.

Some treasury share counts are filled from annual or quarterly reports where no earnings release exists.

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.
