According to Article 3 of our company's "Board of Directors and Functional Committees Performance Evaluation Guidelines," the performance evaluation of the Board of Directors should be conducted at least once every three years by an external evaluation organization or a team of external experts. In 2022, our company commissioned the Taiwan Investor Relations Institute, an external professional organization, to perform the external performance evaluation of the Board of Directors. This organization and its evaluation team have no business dealings with our company and are independent. The relevant details are as follows:

• Evaluation Organization: Taiwan Investor Relations Institute
• Evaluation Period: October 1, 2021 to September 30, 2022
• Evaluation Executing Committee:
  TIRI Taiwan Investor Relations Institute Chairperson 郭宗霖

• Assessment Content and Items: The assessment of the board of directors is based on five major aspects: board composition and professional development, decision-making quality, operational efficiency, internal control and risk management, and the board’s involvement in corporate social responsibility. These aspects are used to evaluate the operational performance of the company’s board of directors.
• Assessment Method: The Taiwan Investor Relations Association conducted the assessment using paper-based self-assessment questionnaires and reviewing written documents provided by the company, including board meeting minutes, current internal policies, other supporting documents, and public information. On October 12, 2022, the association assigned three assessment execution committee members to conduct video interviews with the company’s Chairman, the conveners of the board’s functional committees, the corporate governance officer, and the internal audit officer.
