The board resolved on 23 July to spend 700bn won buying its own shares on the market through Shinhan Investment Securities between 31 July and 22 October, then destroy all of them. At the previous close of 104,500 won that comes to about 6,698,564 shares, roughly 1.43% of the 469,450,239 issued. KB resolved an identical 700bn on the same day, but because KB is larger that money retires only 1.13% of its share count.

The cancellation is made under the proviso to Article 343(1) of the Commercial Act, out of distributable profit, so the number of issued shares falls while paid-in capital does not. The final count will differ from the estimate because it depends on the price paid.

One line in the filing is worth reading for its own sake. Along with the 700bn, the board resolved to cancel a single share — a fractional holding left over from a past comprehensive share exchange — because Article 341-4 requires treasury acquired that way to be retired within a year. A group returning more than 2.8tn won this year stopped to disclose one share.
