2. Responsible Organization (members level and responsibility)

The Board plays a key role in defining IRPC’s vision, key strategies, policies, and plans, taking into account risk factors and laying down suitable management approaches, while ensuring that the accounting, financial, and audit systems are credible.

The Board consists of four sub-committees, namely the Audit Committee, the Nomination and Remuneration Committee, the Corporate Governance Committee, and the Risk Management Committee, to take care of all important issues in the company. The president and executive management are responsible for implementing the policy and principles determined by the Board to be of interest to the company and its stakeholders.

  • Corporate Governance Committee has ensured that IRPC conforms to the corporate governance and sustainability action plans for the year, whether in routine chores or strategic ones. These consist of corporate governance development tasks, environmental governance, and social responsibility tasks aligning with the corporate governance guidelines and sustainability guidelines.
  • Audit Committee reviews the reliability of the financial statements from IRPC and its subsidiaries, as well as the internal control system, internal audit system and risk management system to ensure their suitability and effectiveness. Moreover, it provides recommendations on the improvement of the internal control system.
  • Nomination and Remuneration Committee recruits qualified candidates to nominate as Board members and the President. It has established efficient, transparent procedures and criteria for nomination, so that the Board is made of directors with diverse knowledge, capability and qualifications. Moreover it considers compensation for directors and the President by adopting equitable and reasonable criteria.
  • Risk Management Committee provides oversight of risk management. The Board provides an overall policy, while the Audit Committee reviews the practices. These committees oversee risk assessment analytical exercises, covering potential impacts to IRPC (external and internal, including emerging risks, i.e. cybersecurity, environmental and social perspectives), and to provide risk management reports to the Audit Committee and Risk Management Committee for review.
3. Management System/Process

IRPC’s corporate governance system ensures that a company is managed in the interests of shareholders. It includes checks and balances that enable the Board of Directors to have appropriate control and oversight responsibilities. In addition, management incentives have to be set in such way that management interests are aligned with shareholders’ interests.


Board of Directors
Board Structure

The composition of the Board is in compliance with the Corporate Governance Policy. The Board of Directors must consist of director members that are knowledgeable, skilled, and experienced in IRPC’s business interests. The Board must completely dedicate their time to fulfilling their duties. To this end, IRPC has defined the Board’s composition and key qualifications, as well as the length of their appointment, as follows:

  • The Board consists of 5-15 directors
  • Professional independent directors must number at least one-third of the Board or at least three;
  • Directors may be up to 70 years of age
  • A director can serve up to three successive terms (nine years)

The qualifications of an Independent Director complies with the criteria of the Thai Securities and Exchange Commission (SEC), such as no involvement in management functions of the Company and subsidiary; no blood or legal relation to another Director; no business relationship; and is not an auditor of the company. In addition, the criteria of IRPC are more stringent than the SEC regulation, such as Independent Director must also hold no more than 0.5% of all shares with voting rights of the Company, which is a stricter regulation than that of SEC’s limit of 1%.

Independent directors shall be free to speak their mind at every meeting. They shall attend meetings regularly and have access to sufficient financial and business information, which enables them to express their thoughts freely and in the best interests of stakeholders.

Nonexecutive Chairman/Lead Director

The Board of Directors has to build in the necessary checks and balances to avoid a potential abuse of power by appointing one person to fulfill the roles of Chairman and President.

The principal role of the Chairman is to manage and to provide leadership to the Board of Directors of the company; to promote and oversee the highest standards of corporate governance within the Board and the company; and to lead the Board, particularly in discussions on all proposals put forward by the management team.

Diversity Policy

IRPC supports an appropriate balance and diversity of skills, experience, race and gender, and the appointment of directors must be transparent and comply with the Corporate Governance Policy. The Nomination and Remuneration Committee will recruit and nominate suitable individuals and give an adequate profile for the Board’s consideration. The Board then proposes suitable candidates to the shareholders for approval, taking into account the Board’s diversity policy. When replacing a director that resigns before ending their term, the Board will decide who to appoint. Nomination and Remuneration Committee will consider the qualifications in order to recruit and nominate a suitable person.

Board Effectiveness

The performance assessment of the Board of Directors, specified in the Corporate Governance Handbook, consists of: self-evaluation, performance evaluation of the Board of Directors, performance evaluation of the sub-committees, performance evaluation of the Chairman and Individual Directors, and reporting the results to the Corporate Governance Committee and shareholders. The Nomination and Remuneration Committee reviews the compensation for the Board, gives a recommendation to the Board for approval, and proposes the compensation amount to the annual general meeting for transparent approval based on Compensation Best Practices released by the Thai Institute of Directors Association.

The President and the Executives
Success Metrics for the President Compensation

The Board of Directors has stipulated that the president of IRPC shall submit to an annual performance review by the Nomination and Remuneration Committee. The Board then determines the remuneration of the president based on the results of this review; however, these results are considered undisclosed private information. The criteria were defined to cover challenging targets in accordance with the company’s short-term and long-term strategies, both monetary and non-monetary performances, including social, community and environmental responsibility. The President accepted and harnessed their utmost potential in managing the business and leading the organization forward in line with two assessment indicators: corporate KPIs (worth 70% of the assessment) and supporting factors that boost transparency and sustainability of the company (30%). The 30 percent includes the ability to lead the organization and solve problems that affect IRPC and its stakeholders in a timely manner with accuracy and success in order to create a good corporate image and corporate governance. Details are outlined below


The president’s annual salary adjustment and bonus are dependent on the results of this performance review and are subject to the approval of the Board of Directors. In addition to challenging targets, these criteria comprehend key performance indicators of the company’s strategic plan and vision; corporate responsibilities for communities, society, and the environment; and a balanced scorecard. The remuneration of the president is comparable to that of others within the same or similar industries.

IRPC also performs an evaluation of the company’s performance relative to their peers against a broad spectrum of financial metrics in order to determine how a president’s salary stacks up against the company’s relative financial performance. IRPC calculates its company’s and its peer group’s financial metrics over a three-year period. The weighted average performance rank is compared to the IRPC’s president’s salary rank (relative to peer company president’s salary) to yield a relative financial performance results.
