CMI has elected directors according to the law since it was incepted. Candidates are selected in terms of expertise, social experience and moral standards. The board of directors is formed by five members, including two independent members, with professional background and rich technical experience in related fields, and three supervisors.  They are co-responsible for CMI's strategic planning, operations and supervision.

According to the procedure for meetings of the board of directors, the board shall hold a board meeting at least every quarter. Supervisors can communicate with CMI financial, legal affairs and internal audit officers at the quarterly board meetings to understand the internal risk control, major litigation risk assessment and internal reports of CMI. With the internal (audit office) and external (CPA) annual audit programs and financial report certification, the status of legal compliance, including the laws and regulations and financial and accounting principles governing listed companies, and the target accomplishment rate of CMI are identified.

It is also specified in the procedure for meetings of the board of directors that when the directors, or their agents, have a conflict of interest with alleged harm on the CMI’s interests, they may express their opinions and answer the enquiries, but shall not participate in the discussions or voting. Also, they shall abstain from the discussions and voting and shall not exercise the right of voting for and on the behalf of other directors. According to Paragraph 2 of Article 206 of the Company Act, Paragraph 2 of Article 180 of the Company Act applies mutatis mutandis to the directors who are prevented from exercising their right of voting according to the foregoing section for resolutions made at the board meeting.
