Board of Director’s Performance Assessment

GC determines that the performance of Board of Directors and Sub-committees must be assessed every year, and an external consultant may be requested to assist in establishing guidelines and providing recommendation of the board assessment as deemed necessary and appropriate every three years. This is to enable the Board of Directors to review and revisit their performance, issues and obstacles having arisen in the past year, which help lead to the development and improvement of the Board of Directors’ performance. In 2022, EY Corporate Services Company Limited (EY) was appointed as GC’s independent third-party consultant for the 2022 Board Performance Assessment project in accordance with the Thai Corporate Governance Code for Listed Companies 2017 (CG Code) issued by the Securities and Exchange Commission (SEC). The scope of project includes the improvement of quality of GC’s Group Assessment, Self-assessment, and Cross-assessment Forms and the annual performance assessment by means of conducting individual interviews in comparison with assessment scores as well as the preparation of an analysis report on the assessment results and the recommendation of the Board of Directors. This project enables GC to further improve, monitor and enhance the Board’s performance. In addition, the Board Performance Assessment consists of eight main components as follows;

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 Director Certification Program (DCP), Director Accreditation Program (DAP) and Board that Make a Difference. GC also encourages directors to participate in specific training programs, such as Audit Committee Program (ACP), and Role of the Nomination and Governance Committee.

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.

Moreover, GC has invited external experts and leading company to lecture and share knowledge in important issues that are currently happening in the year 2022 e.g., Strategic Business Foresight, hosted by invited speakers from the Thai Institute of Directors Association (IOD), to inform them of key trends and challenges and enable them to apply the foresight mindset and process to formulate GC’s long-term strategies, as well as a session on the topic “The Future of Decarbonization,” led by invited speakers from McKinsey to update them on the outlook and trends of carbon capture, utilization and storage (CCUS), and hydrogen technology at both domestic and global levels (Global and Thailand Outlook).
