Splits: 2013-07-01: 100-for-1 split; 2015-07-01: 3-for-1 split; 2017-09-01: 2-for-1 split (effective date)

※ 2015-12: 3-for-1 split; 2017-12: 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.

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.
