treasury shares financial

"resolution made by the board of directors of Financial Group to cancel certain of its treasury shares."

Treasury shares are a company’s own stock that it has repurchased and keeps on its books instead of canceling or leaving in the hands of outside investors. Think of them like coupons a business puts back in a drawer: they don’t vote or receive dividends while held, but they can be reissued later for employee pay or fundraising. For investors this matters because buybacks change the number of shares that count toward earnings and ownership, can boost per‑share metrics, and use corporate cash that might otherwise go to growth or dividends.

paid-in capital financial

"the total number of issued shares (common shares) will decrease, but there will be no reduction in the paid-in capital of KB Financial Group."

Paid-in capital is the cash and other assets shareholders have given a company in exchange for its stock, including amounts paid above the stock’s nominal value. Investors care because it shows how much funding came directly from owners rather than from borrowing or profits, affecting the company’s financial cushion, ownership dilution and how resilient it may be in tough times — like the extra money people pay above a ticket price to support a project they believe in.

profits available for the payment of dividends financial

"treasury shares acquired within the limits of profits available for the payment of dividends."

Commercial Code of Korea regulatory

"Legal basis for the cancellation of treasury shares: Article 343-1 of the Commercial Code of Korea."
