6.Initiatives for governance

1)Basic concept

We are striving to increase the corporate value and stably grow in long term. To achieve this, we are aware that it is important to contribute to building an affluent society and build a good relationship with all stakeholders though our business activities. Under this concept, we advance initiatives to ensure adequate corporate governance.

(5)We strive for a constructive two-way communication with stockholders to provide proper information in timely manner.

3)Overview of the current corporate governance framework

TRS has adopted an auditor system. We have established the Board of Directors and the Board of Auditors as company organizations specified in the Companies Act to proceed with resolution, supervision, and audit for important operation execution. Furthermore, we have established the Board of Executive Officers and the Global Compliance Committee as supplemental organizations

(1) Board of Directors

The Board of Directors consists of five directors including two external directors. In principle, the Board of Directors meeting is held once each month. If necessary, a special meeting is held to deliberate and resolve on the matters of important operations. All auditors attend the Board of Directors meeting and provide opinions as necessary.

(2)Board of Auditors

The Board of Auditors consists of four auditors including two external auditors and one full-time auditor. Each auditor attends the Board of Directors meeting as well as audits general operations of directors according to the audit policy established by the Board of Directors.

(3)Board of Executive Officers

The Board of Executive Officers consists of eight executive officers. They discuss important matters of management in advance, proceed with operations to the extent of authorization commissioned by the Board of Directors, and deliberate and resolve on the matters of measure execution, etc.

(4) Global Compliance Committee

The Global Compliance Committee consists of all executive officers and those of affiliated companies. This has been established in order to confirm the compliance status of laws, articles of incorporation, and in-house regulations.

(5)Governance Committee

The Governance Committee consists of external directors and auditors, and the President. The Board of Directors consults this committee regarding important matters such as the basic policy of appointment and reward. The external director serves as the Chair.

4)Basic concept of the internal control system and its development status

Decision overview on the system for ensuring that directors’ duties are executed in compliance with laws and articles of incorporation, and the system for ensuring the appropriateness of company’s other operations is as follows.

(1) System for ensuring that directors’ and employees’ duties are executed in compliance with laws and articles of incorporation
  • TRS Group Code of Conduct is established so that executives and employees behave in accordance with to laws, articles of incorporation, and norms in society.
  • The general affairs department controls initiatives for compliance across departments, and play a center role of education for executives and employees.
  • An easy voice system (whistle-blower system) is established as a means of direct information provision by employees, thereby striving to identify doubtful behavior in terms of legal compliance.
  • We have no relationship with anti-social forces. We respond to undue claims of anti-social forces with resolute attitude throughout the organization. If any director or employee is approached by such forces, that person promptly reports it to the immediate superior and relevant department, and follows their directions.
  • Furthermore, if any director or employee encounter an illegal or criminal conduct such as fraud/extortion directly or indirectly during work, or a situation where such conduct is likely to occur, that person promptly reports it to the immediate superior and relevant department while responding to such forces with resolute attitude, and follows their directions.
  • We maintain and strengthen the internal control system for ensuring reliability of the financial reporting based on the Financial Instruments and Exchange Act, and related rules and standards.
(2) Storage and control system for information related to directors’ duty execution
  • Decision documents such as directors’ meeting minutes related to directors’ duty execution or approval documents for decision making based on the administrative authority standard are stored and controlled by the responsible department according to the document control rules.
  • Directors and auditors can browse these documents at any time.
(3) Rules and other systems for managing risks of loss
  • In order to maintain and enhance the risk management framework, we regularly hold a “Risk Management Committee” meeting to continuously consider important matters, and perform cross-sectional control such as establishment of rules and guidelines, training execution, and manual creation/distribution. For newly raised risks, we promptly appoint a director as an officer responsible and minimize each risk.
(4) System for ensuring that directors’ duties are executed efficiently
  • The Board of Executive Officers, for which the President serves as the Chair, is established under the Board of Directors. The Board of Executive Officers discusses important matters of management in advance, proceeds with operations to the extent of authorization commissioned by the Board of Directors, and deliberates and resolves on the matters of measure execution, etc.
  • The Board of Executive Officers establishes the medium-term management plan and the yearly profit plan for operation, and company-wide goals. To achieve these goals, the administrative authority of directors and tasks for which they are responsible are clarified, thereby improving efficiency in duty execution.
(5) System for ensuring the appropriateness of operation of a company group that consists of our company and its parent and affiliated companies
  • Each department of our company works in mutual cooperation with relevant departments of the parent company to execute an appropriate and efficient group management.
  • Although we, as a member of the group, may implement a procedure to report certain important matters we carry out to the parent company for confirmation, we make our own decision as a listed company independently of the parent company.
  • We notify our policy to and share our information with the groups’ affiliated companies in regular meetings such as the Board of Executive Officers meeting. Meanwhile, based on the DOA rules, we require the report on certain important matters from each company and confirmation to us, thereby ensuring the appropriateness of operation of the group’s affiliated companies. In addition to this, the TRS Group Global Code of Conduct, which is applicable up to the group’s affiliated companies, is established. Meanwhile, the group’s affiliated companies establish their own code of conduct, striving to be in compliance with laws and articles of incorporation as a group. Furthermore, the group’s affiliated companies also introduce an easy voice system (whistle-blower system), and report the violation of laws or articles of incorporation if they occur.
  • Internal auditor office regularly audits the affiliated companies to confirm the status of compliance with laws and articles of incorporation and risk management.
(6) Matters concerning employees if auditors require the appointment of supportive employees for their duties, and matters concerning such employees’ independency from the directors and ensuring effectiveness of the directions given to such employees from the auditors
  • If auditors require supportive employees for their duties, consultation with auditors is held and employees are appointed as full-time or concurrent staff members.
  • For ensuring independency from directors and effectiveness of the directions given to such employees from auditors, such employees proceed with their duties according to the directions given from auditors. Regarding personnel change and evaluation related to such employees, agreement from auditors is needed.
(7) System for reporting to the Board of Auditors or an auditor from directors or employees, and system for reporting to other auditors
  • Based on the request from auditors, directors and employees explain the status of duty execution as well as report important decisions of our company and our group, policy, and management status in various board meetings in which auditors participate.
  • Directors and employees report the status of duty execution and issues to be discussed in a regular department audit that is based on the annual audit plan created by auditors.
  • The internal audit office regularly reports audit results to the Board of Auditors.
(8) System for ensuring that audit is effectively executed by the Board of Auditors or auditors
  • Opportunities for regular opinion exchange between auditors and the President are provided, and auditors receive regular audit reports from the auditing company
  • Budget for expenses is discussed in an advance consultation, and proper actions are taken to ensure payment in accordance with laws.
  • We do not treat a person who reported to auditors unfavorably because of his/her reporting.
