II. Responsible Organization (member’s level, responsibility)
The Board plays a key role in defining IRPC’s vision and key strategies, policies, and plans, taking into account risk factors and laying down suitable management approaches, while ensuring that 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 with the president and the executive management being responsible for implementing the policy and principles determined by the Board to be of interests of the company and its stakeholders.

  • Corporate Governance & Sustainability Committee has ensured that IRPC conforms to the corporate governance and sustainability action plans for the year, whether in routine chores or in 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 statement of IRPC and its subsidiaries, 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 for nomination as Board members and the CEO. It has established efficient, transparent procedures and criteria of 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.

These committees are to ensure risk assessment analytical exercises, covering potential impacts on IRPC (external and internal, including environmental and social perspectives), and to provide risk management reports to the Audit Committee and Risk Management Committee for review.
