The Audit & Supervisory Board comprises all of the Audit & Supervisory Board Members responsible for auditing the decision-making processes and management performances of Directors in compliance with the Companies Act, and other laws and regulations as well as Mitsubishi Corporation’s Articles of Incorporation and internal rules/regulations.
Full-time Audit & Supervisory Board Members ensure the soundness of the management by executing audits from a perspective based on abundant working experience at MC, while Independent Audit & Supervisory Board Members execute audits with a background of abundant working experience in their particular fields as well as neutral and objective perspectives. In addition to resolutions of matters required by law and other important issues, the Audit & Supervisory Board strives to enhance information-sharing among the members through briefings on key matters and reporting the status of auditing activities for each of the members.

Prior to the start of each fiscal year, the Audit & Supervisory Board formulates audit plans with key areas. In the fiscal year ended March 31, 2021, the following three key audit areas were selected for the monitoring of specific progress in management and execution.

1. 1Dialogue with executive officers

   Audit & Supervisory Board Members engage in dialogues with the Chairman of the Board, President and CEO, Corporate Functional Officers, Business Group CEOs, Business Division COOs, Administrative Department General Managers, General Manager of Auditing Department, General Manager of the Corporate Strategy & Planning Department and General Managers of the Corporate Staff Section. In the fiscal year ended March 31, 2022, 65dialogues were held, and at least one Independent Audit & Supervisory Board Member participated in 62 of these dialogues.

   

2. 2Attendance at important meetings

   Besides the Audit & Supervisory Board meetings, the Full-time Audit & Supervisory Board Members attend meetings of major internal management bodies, including the Board of Directors; the Governance, Nomination and Compensation Committee; the Executive Committee and the Business Strategy Committee; and provide necessary opinions (130 times in the fiscal year ended March 31, 2022). Besides the Audit & Supervisory Board meetings, the Independent Audit & Supervisory Board Members attend meetings of the Board of Directors after being briefed of discussions in the Executive Committee and lower conference bodies, and provide necessary opinions (25 times in the fiscal year ended March 31, 2022).

   

3. 3On-site audits and observations

   Audit & Supervisory Board Members proactively conduct on-site audits and visits of overseas and domestic MC Group companies in an effort to grasp the local circumstances. In selecting the locations of the on-site audits and visits for the Audit & Supervisory Board Members, besides quantitative aspects such as investment amount and net income, qualitative aspects such as the business environment and compliance cases are also taken into account.
   Amid ongoing restrictions on movement due to the COVID-19 pandemic, the Audit & Supervisory Board fulfilled its duties while adapting to the situation by enhancing onsite audits and observations in Japan and conducting remote audits of overseas sites using a variety of tools. 
   In the fiscal year ended March 31, 2022, dialogues were held with the CEOs and executive officers of 3 companies in 3 countries overseas and 15 domestic MC Group companies, as well as the regional heads of 11 overseas and domestic offices. The Audit & Supervisory Board Members reported on the results of their on-site audits and visits to the Chairman of the Board, the President and CEO, and relevant executive officers.
   At least one Independent Audit & Supervisory Board Member participated in on-site audits and visits with 3 companies in 3 countries overseas and 14 domestic MC Group companies, as well as 9 overseas and domestic offices.

4. 4Reinforcement of Group Corporate Governance

   In addition to dialogues with the CEOs and other executive officers of the MC Group companies, opportunities are arranged for the exchange of information every quarter with the Audit & Supervisory Board Members of 39 major Group companies in Japan, and Audit & Supervisory Board Members of the MC Group companies also hold subcommittees to provide opportunities to share information and exchange opinions. We also provide assistance in training for those who will be assigned to the MC Group companies as full-time Audit & Supervisory Board Members. We will continue working to strengthen the Group corporate governance through regular monitoring.

Enhancing the Effectiveness and Auditing Activities of the Audit & Supervisory Board (Members)

MC conducts annual evaluations of the Board of Directors in order to make continuous improvements to the effectiveness of its corporate governance. The Audit & Supervisory Board (Members) focused on the following matters, referring to the issues reviewed in the effectiveness evaluation. 

1. Improving the scope of information sharing on important investment and loan projects

   For matters to be submitted for approval or reported to the Board of Directors, preliminary briefings are held for Independent Directors and Independent Audit & Supervisory Board Members by management on the executive side prior to deliberation by the Board of Directors. For the Audit & Supervisory Board, in addition to these preliminary briefings, members also receive explanations from Audit & Supervisory Board staff related to Board of Directors matters of especially high importance as well as matters that are not quantitatively applicable to the Board of Directors but that are still qualitatively important. Audit & Supervisory Board Members then exchange opinions and share their awareness of risks in relation to the loan and investment projects.

2. Enhancing the provision of Information to Independent Directors and Audit & Supervisory Board Members through various dialogues hosted by the Audit & Supervisory Board Member's office

   As an activity of the Audit & Supervisory Board Members, MC has traditionally provided opportunities for discussion between all Audit & Supervisory Board Members and management executives such as the Chairman, President, Corporate Officers and Group CEOs. As in the previous fiscal year, Independent Directors also actively participate. In addition, since the fiscal year ended March 2021, we have incorporated Business Reports from senior management, which used to be held at meetings of the Board of Directors, into this dialogue, allowing sufficient time for the provision of information, including questions and answers. Independent Audit & Supervisory Board Members also participate in dialogues with the Division Chief Operating Officer to ensure opportunities to hear the opinions of employees on the ground.

3. Enhancing the Effectiveness of the Audit & Supervisory Board and Its Members

   To increase the effectiveness of the audits performed by Audit & Supervisory Board Members, in the year ended March 31, 2022, we further enhanced the reviews of the activities of the Audit & Supervisory Board conducted in previous years. Specifically, the secretariat held mid-year and year-end hearings with each of the Audit & Supervisory Board Members to identify insights about overall auditing activities and things to improve in the coming year respectively. The results were shared and discussed among the Audit & Supervisory Board Members. At these hearings, the participants also discussed the progress of auditing in the key audit areas designated at the start of the fiscal year, and insights from these discussions were then fed back to executives. Through such new processes and other means, we sought to improve auditing methods.

Enhancement of Three-Way Audits

Audit & Supervisory Board Member Audits

The 2 In-house Audit & Supervisory Board Members each have experience in the corporate management, and finance and accounting departments, and they are appointed as Full-time Audit & Supervisory Board Members, respectively. The 3 Independent Audit & Supervisory Board Members each have many years’ experience as an attorney (corporate law) and certified public accountant, and experience as Full-time Audit & Supervisory Board Member at a listed company, respectively.

At the same time, Audit & Supervisory Board Members hold regular meetings with Mitsubishi Corporation’s independent auditors and Internal Audit Department, to accurately and in a timely manner grasp Mitsubishi Corporation’s situation through close cooperation.

In the fiscal year ended March 31, 2022, Audit & Supervisory Board were held 12 times, and all Audit & Supervisory Board Members were in attendance at every meeting. At the first Audit & Supervisory Board for the fiscal year, the audit plan for that fiscal year is decided upon and a review of the previous fiscal year’s audit activities is carried out. These matters are also reported to the Board of Directors. Furthermore, in addition to statutory matters such as the audit report and the selection and dismissal, and remuneration of the independent auditors, the Audit & Supervisory Board also discusses major investment and finance projects and issues identified through audit activities such as on-site audits, tours and dialogues, etc.

Internal Audits

Regarding internal audits, the Internal Audit Department (which had 83 members as of April 1, 2022) conducts audits of MC and its overseas regional subsidiaries and affiliated companies from a Company-wide perspective. In addition, each Business Group has established its own internal audit organization, which audits the operations that fall under its Group organization on a consolidated basis. These internal audits are based on annual audit plans and are conducted after selecting audit targets. The audit results are reported each time to the President and CEO, Audit & Supervisory Board Members and other concerned parties. They are also reported regularly to the Board of Directors and the Executive Committee.

Accounting Audits

The three certified public accountants who carried out the accounting audit of Mitsubishi Corporation were Yuki Higashikawa, Hirofumi Otani and Sogo Ito of Deloitte Touche Tohmatsu LLC. They were assisted by 29 certified public accountants, 18 junior accountants and 56 other staff.

Mutual Cooperation among Audit & Supervisory Board Member Audits, Internal Audits and Accounting Audits, and their Relationship with Internal Control Departments

The Audit & Supervisory Board Members, Corporate Accounting Department, and independent auditors hold regular meetings at the time of quarterly financial results and monthly, and provide opportunities for exchanging opinions with subsidiaries and affiliates as necessary.
In addition, the Internal Audit Department makes regular audit reports to the Audit & Supervisory Board, the Audit & Supervisory Board Members have monthly meetings with the Internal Audit Department, and the Audit & Supervisory Board Member and the Internal Audit Department hold liaison meetings with the Audit & Supervisory Board Members and internal audit departments of subsidiaries and affiliates, and so forth.
