Splits: 2013-10-01: 100-for-1 reverse split; 2018-02-01: 5-for-1 split (effective date)

※ 2018-03: 5-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 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.

2015, 2016, 2017, 2018, 2019: reported buybacks net of proceeds from disposing of treasury shares. Years where disposals exceeded repurchases are negative.
