Candidates will be considered regardless of their sexual preference, nationality, ethnicity, race or religious faith as diversity and inclusion can contribute to a broad range of perspectives that are crucial to the company’s business operations.

Eight directors qualified as independent directors. Together, the directors contributed to the effectiveness of the Board in the discharge of its duties.

Independent Directors The company has determined that the number of independent directors shall be not less than one-third of the total number of members of the Board of Directors. The term of office of the independent director shall be equal to that of the company’s executive director, which is not more than three years. They may be re-appointed by the shareholders for not more than three consecutive terms, or up to a combined total of nine years in office, without exception. In addition, independent directors must be independent from major shareholders or groups of major shareholders, and the management of the company. The qualifications of the independent director are stricter than minimum requirements imposed by Notification of the Capital Market Supervisory Board regarding shareholding limit in the company at not more than 0.5 per cent. The definition of the independent director has been disclosed in the Good Corporate Governance Handbook and the company’s website. Independent directors may speak their minds during Board meetings and have adequate access to the company’s financial data and business information to enable them to express their views freely in the best interest of stakeholders and prevent possible conflicts of interest involving the company, the management, executive directors or major shareholders.่ 3.
