Board Effectiveness and Compensation
Board of Director’s Performance Assessment
GC requires that the performance of the Board of Directors and sub-committees must be assessed on an annual basis using three forms of assessment, namely Group Evaluation, Self-evaluation, and Cross Evaluation, by means of individual interviews. This enables the Board of Directors to review performance, problems and obstacles throughout the year, leading to development and improvement for greater operational efficiency. An external consultant has been contracted to assist in determining guidelines and providing recommendations in performance evaluation in line with the guidelines of the Corporate Governance Code for Listed Companies 2017 of the Security and Exchange Commission (SEC) as well as national and international corporate governance principles every three years. The main components in evaluating the performance of the Board of Directors consist of the following eight aspects:
Board structure and performance
GC Group structure
Behavior and culture
Governance of regulatory bodies
Board composition
Roles, duties, and responsibilities
Trainings and development of knowledge and skills
Governance of disclosures and performance assessment

Board of Directors’ Knowledge Development
GC encourages all directors to receive necessary training programs related to the Board’s capability and knowledge development from Thai Institute of Directors Association (IOD) and other organizations every year. This training would enhance the board’s knowledge and perspective needed to apply to GC businesses. The essential training programs for directors to perform his/her role include the Director Certification Program (DCP), Director Accreditation Program (DAP), and the Board that Makes a Difference (BMD) program, as well as other specialized courses such as the Audit Committee Program (ACP) and the Role of the Nomination and Governance Committee (RNG) program.
Moreover, all new directors are also required to participate in Board orientation class and to visit GC’s different plant operations, and participate in various activities so that the boards can understand GC’s working approach and business model, including encouraging directors to participate to exchange opinions with experts who have experience at the national and regional levels. This would enhance directors’ knowledge so that they would apply to GC business management, and it would help promote and leverage an understanding of corporate governance, which benefits the Company’s business management.
In 2024, GC invited external experts and leading company to lecture and share knowledge in important issues that are currently happening in the year, such as a training session was conducted for Board members on the topic “Petrochemical Market Landscape” by consultants from Bain & Company, aimed at providing insights into industry and market trends in the petrochemical and chemical sectors. The session also covered risk assessment and mitigation measures for potential business impacts. This knowledge supports the Board in strategic direction setting, business planning, governance, and identifying opportunities for competitive business expansion.
