Appendix 2: Explanation of voting methods for electing directors and independent directors using the cumulative voting system

  1. The election of candidates for directors of the shareholders’ meeting and the election of independent director candidates are numbered as separate proposal groups. Investors should vote for each candidate under each proposal group.

  2. The number of declared shares represents the number of electoral votes. For each proposal group, each share held by a shareholder shall have a total number of votes equal to the number of directors to be elected under that proposal group. If a shareholder holds 100 shares of a listed company, 10 directors should be elected at the shareholders' meeting, and there are 12 director candidates, then the shareholder has 1,000 votes for the board of directors election proposal group.

  3. Shareholders shall vote within the limit of the number of electoral votes for each proposal group. Shareholders can vote according to their own wishes. They can either concentrate their votes on a certain candidate or vote on different candidates in any combination. After the voting ends, the votes for each motion will be cumulatively calculated.

  4. Example:

A listed company convened a shareholders' meeting to re-elect the board of directors using a cumulative voting system. There were 5 directors to be elected, and there were 6 director candidates; 2 independent directors were to be elected, and there were 3 independent director candidates. Matters subject to voting are as follows:
