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 Director’s Remunerations

The Board of Directors has established a fair and reasonable remuneration policy for its directors in accordance with the good corporate governance principles. In this way, the Nomination and Remuneration Committee has a duty to determine suitable remuneration and payment of bonus for Board of Directors and Sub-committees based on the results of board performance assessment, economic situation, the Company’s operating results, and the remuneration of Directors in other companies of a similar size and nature of business as well as directors’ responsibilities.

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, 2023 such as “What’s and Why’s for Board of Directors to Guide a Refining & Pet-Chem Company” by consultants from the Petroleum Institute of Thailand to enhance knowledge, understanding and perspectives on business operations for the Board of Directors and executives to keep up to date with the situation and constantly competitive business conditions, as well as a lecture on “Decarbonization Roadmap & 5Y Plan GC” by GC’s senior executives to discuss the guidelines and goals for reducing greenhouse gases according to the company’s Decarbonization Pathways, which also serve as information to formulate the Company’s strategic sustainability plan.
