Mitsui : Corporate Governance Report

Corporate Governance Report

Last Update: April 7, 2021

Mitsui & Co., Ltd.

President and CEO Kenichi Hori Contact: Investor Relations Div. [phone] Securities Code: 8031 https://www.mitsui.com

The corporate governance of Mitsui & Co., Ltd. (the "Company" or "Mitsui") is described below.

1. Basic Views on Corporate Governance, Capital Structure, Corporate Profile and Other Basic Information

1. Basic Views

[Basic Corporate Governance Policy]

In structuring the corporate governance framework, Mitsui places emphasis on "improved transparency and accountability" and "the clarification of the division of roles between the oversight activities and executive activities of the management."

For the "improved transparency and accountability," Mitsui ensures sound supervision and monitoring of management with the view point of External Directors and External Audit & Supervisory Board Members (hereinafter referred to as the "external members"). Mitsui has also established an internal control system for disclosure so that all executives and employees fulfill their accountability to stakeholders under the principle of fair disclosure. For "the clarification of the division of roles between the oversight activities and executive activities of the management," Mitsui delegates execution of business to Managing Officers substantially while the Board of Directors retains a supervisory role over Managing Officers' business activities. Chief Operating Officers of 16 business units within headquarters and 3 regional business units serve concurrently as Managing Officers and engage in business operation for the consolidated group in a responsive and flexible manner.

While increasing the effectiveness of supervisory functions by having Audit & Supervisory Board Members, Mitsui implements corporate governance by maintaining an Audit & Supervisory Board system because it believes that having internal Directors who are familiar with our business practices and operations is essential to the business of a general trading company. By adopting a Committee System in which external members participate, Mitsui achieves highly effective corporate governance to secure "improved transparency and accountability" and "the clarification of the division of roles between the oversight activities and executive activities of the management." In order to realize effective corporate governance for shareholders and other stakeholders, Mitsui has established, and maintains, the following structures:

- 1 -

1. The Board of Directors is the highest authority for execution of business and supervision, and in order to secure this function, the number of directors shall be set at an appropriate number where effective discussion is possible. As advisory committees to the Board of Directors, Mitsui also has in place the Governance Committee, the Nomination Committee and the Remuneration Committee, in which External Directors and/or External Audit & Supervisory Board Members participate as members.
2. The Audit & Supervisory Board Members supervise the Directors' execution of duties as an independent institution with the mandate of the shareholders. For this purpose, Audit & Supervisory Board Members carry out multi-faceted, effective audit activities such as attending important internal meetings, verifying reports and investigating our business, and take necessary measures in a timely manner.

Regarding Mitsui's basic views and policies on Corporate Governance, we published "Mitsui & Co., Ltd. Corporate Governance and Internal Control Principles" on Company's website as follows. (https://www.mitsui.com/jp/en/company/outline/governance/system/pdf/corp_gov.pdf)

(Notes)

"External Director", "Audit & Supervisory Board Member" and "External Audit & Supervisory Board Member" are used in the same sense of "External Director", "Kansayaku" and "External Kansayaku" in the heading of the format of this Corporate Governance Report respectively. Further, "Independent Director" is an External Director who is unlikely to have conflicts of interest with general shareholders, as stipulated by the Tokyo Stock Exchange.

[Reasons for Non-compliance with the Principles of the Corporate Governance Code]

Mitsui complies with all Principles of the Corporate Governance Code.

[Disclosure Based on the Principles of the Corporate Governance Code]

[Principle 1.4 Cross-Shareholdings]

• Policy related to acquisition and holding of cross-shareholdings
  Mitsui defines listed shares held for reasons other than purely for investment returns as cross- shareholdings. Cross-shareholdings here include not only mutual shareholdings but also unilateral ones. These are acquired and held in accordance with the following policy.
• 1. The purpose of cross-shareholdings in investees for which the equity-method is applicable is to improve the corporate value of the investees and increase equity-method based profit and dividends to be received through participation in the management of the investees. Cross- shareholdings in companies other than equity-method applicable investees (including deemed shareholdings) will be categorized as "listed shares for general investment purposes" and regarded as a means of creating business opportunities and building, maintaining, or strengthening business and collaborative relationships.
  2. Investments in the shares of equity-method applicable companies are implemented only in cases where the economic rationale is recognizable. At the same time, each year the Board of Directors

- 2 -

shall review the meaning of and policy on holding such shares, including a verification of the rationale in relation to our cost of capital, within the framework of portfolio reviews that are carried out in relation to investment assets generally, including unlisted shares. If the meaning of holding these assets has significantly declined, a policy toward withdrawal shall be set out.

• 1. When acquiring listed shares for general investment purposes, the Company shall conduct a prior stringent assessment of the probability of the investment creating business opportunities, or building, maintaining, or strengthening business and collaborative relationships. At the same time, each year, the Board of Directors shall review the meaning of and policy on holding listed shares for general investment purposes by verifying the economic rationale based on the status of dividends, business-related profits, and other related profits, in comparison to our cost of capital, and verification of qualitative aspects based on the status of and outlook for the creation of business opportunities, as well as business and collaborative relationship with each cross- shareholding investee. If as a result of this review the meaning of holding these assets has significantly declined, our policy is sell such assets thereby reducing the cross-shareholdings.
• Result of verification at Board of Directors meeting
  Details of verification by the Board of Directors concerning the cross-shareholdings as of March 31, 2020 are as follows.
  Equity-method applicable investees:
  With regard to every individual stock, checked if it falls under the exit criteria specified within the Company, consisting of the profitability and qualitative criteria. As a result, we confirmed the policy as to whether to hold, exit or continue to temporarily hold to watch those stock that fall under the exit criteria.
  Listed shares for general investment purposes:
  As far as economic rationality is concerned, confirmed that the related profit exceeds our cost of capital in about 60% of the individual stocks as a result of verification of the related profit situation, including dividends and related trading profit compared with our cost of capital vis-à-vis the amount shown in the balance sheet at the end of the term for every individual stock. At the same time, verified and confirmed the qualitative rationale for holding every individual stock. Confirmed the stocks where future sale will be considered as a result of a lessening of the rationale for holding based on both qualitative and quantitative aspects.
• Policy on the exercise of voting rights
  With respect to the exercise of voting rights of listed shares held by the Company, the content of each proposal shall be considered in relation to the management policies and business plans, etc., of the investee, and deliberation shall be conducted on a case-by-case basis by taking into consideration comprehensively from the perspectives of (1) whether or not the proposal contribute to enhancing corporate value of the investee or mutual benefit of the shareholders, and (2) the impact that the proposal may have on the enhancement of the corporate value of the Company in terms of the creation of business opportunities, and building, maintenance, and strengthening of business and collaborative relationship between the investee and the Company.

[Principle 1.7 Related party transactions]

Mitsui seeks for resolution of the Board of Directors concerning transactions between the Company and a Director, Managing Officer or major shareholder in accordance with laws and regulations and the Internal Regulations on Matters to Be Resolved or Reported at the Meeting of the Board of Directors, and reports periodically to the Board of Directors on important transactions with subsidiaries and associated companies.

[Principle 2.6 Roles of Corporate Pension Funds as Asset Owners]

Mitsui's corporate pension fund ("Corporate Pension Fund") is managed with the aim of securing the profit needed to ensure the disbursement of pensions and lump-sum payments, and building up quality pension assets. Mitsui assigns people with the specialist knowledge and appropriate qualities deemed necessary to manage the pension fund in line with said objectives.

The Corporate Pension Fund has established an asset management committee. Pension assets are managed based on the deliberations by the asset management committee and in accordance with the subsequent decisions of the Board of Directors and board of trustees. For the asset management committee and board of trustees, Mitsui has assigned personnel with appropriate qualities for the task, such as its officers and employees engaged in such areas as human resource management, financial management, accounting, risk management, and legal affairs. At the same time, by assigning employees who represent the fund subscribers, it has created frameworks to carry out various tasks, such as the formulation of basic fund management policies, the allocation of basic assets based on certain strategies, the selection and assessment of fund management institutions, and monitoring of the fund management status. They have assigned people, such as officers or employees, who are from Mitsui, to also properly manage the issue of conflicts of interest between the Corporate Pension Fund beneficiaries and the Company with regard to the formulation and administration of these organizational frameworks.

The Corporate Pension Fund possesses assets, such as investment trusts and pension insurance, in accordance with the basic fund management policy and strategic allocation policy of base assets, and entrusts the fund management with contract fund management institutions by providing contract institutions with these fund management guidelines. The Corporate Pension Fund shall formulate stewardship policies, monitor the stewardship activities of entrusted fund management institutions, and submit reports to the asset management committee, the Board of Directors, and the board of trustees, etc.

[Supplementary Principle 4.1.1 Scope and content of the matters delegated to the management]

Apart from deciding basic policy related to Mitsui management, items related to important operational execution, and items authorized by resolutions of the General Meetings of Shareholders, the Board of Directors decides items provided for in laws and regulations along with the Company Articles of Incorporation, in line with Internal Regulations on Matters to Be Resolved or Reported at the Meeting of the Board of Directors. Moreover, by receiving reports on items provided for in laws and regulations and the status of the execution of important operations, the Board of Directors oversees the execution of duties by the management headed by the President, who serves as Chief Executive Officer.

Based on the basic design of internal controls provided for by the Board of Directors, the management assumes the role and responsibility of maintaining, operating and assessing internal controls at Mitsui and Mitsui affiliated companies.

Mitsui adopts a Managing Officer system so that Directors perform their management duties in an efficient manner. Managing Officers are appointed by the Board of Directors and are delegated authority by the Board of Directors.

Mitsui's product-based Head Office Business Unit are aligned to its products and services, with Regional Business Units in the Americas, the EMEA (Europe, Middle East and Africa), as well as Asia Pacific, making it possible for each Chief Operating Officer to implement timely, locally-based management decisions by delegating certain authority to each of them in accordance with Mitsui's Regulations on delegation of authority. Mitsui implements an internal approval system for matters which are beyond the delegated authority of each Chief Operating Officer. Within such system, Mitsui's Representative Directors make final decision in the best interests of the Company, following deliberations conducted by the relevant Corporate Staff Divisions on their capacities and specialist areas.

[Principle 4.8 Effective use of independent directors]

The number of directors shall be set at an appropriate number where effective discussion is possible. The Company's policy shall be that at least one-third of the total number of directors shall be independent external directors.

[Supplementary Principle 4.11.1 A view on the appropriate balance between knowledge, experience and skills of the board as a whole, and also on diversity and appropriate board size]

- 6 -

The number of directors shall be set at an appropriate number where effective discussion is possible, and from the standpoint of promoting the division of roles between the oversight activities and executive activities of the management, priority is given to External Directors when increasing numbers. Mitsui has decided that as the appointment standard for External Directors, the prospective person's extensive business experience and knowledge are required to deliberate on such Board of Directors meeting proposals as investments and loans, and knowledge of his or her particular area of business is used. Mitsui has decided that in selecting candidates for the positions of External Director, it puts great value on ensuring their independence from Mitsui in the pursuit of their management oversight functions. Also, with a view to overseeing business operations in a way that reflects the standpoint of our diverse stakeholders, Mitsui takes into consideration the field from which candidates originate, along with their gender.

Through discussions by the Nomination Committee and Board of Directors about ways to ensure the effectiveness of the Board of Directors and the Audit & Supervisory Board, Mitsui has formed a Board of Directors with a composition that achieves a good balance between diversity including gender and national diversity, and an appropriate size. Also, Mitsui has appointed people with appropriate experience and capabilities as Audit & Supervisory Board members.

Policy on Determining Remuneration Amounts and Calculation MethodsEstablished

Disclosure of Policy on Determining Remuneration Amounts and Calculation Methods

Remuneration for Directors (excluding External Directors) is determined by a resolution of the Board of Directors on the basis of deliberations by the Remuneration Committee, which is chaired by an external member. It consists of basic fixed remuneration, performance-related bonus based on Mitsui's key performance indicators, and stock-based compensation linked to the stock price as medium to long-term incentive compensation. In the year ended March 31, 2020, replacing stock-based compensation linked to the stock price provided in the form of stock options, we have adopted a remuneration system with share performance-linked restricted stock. Also, each Director (excluding External Directors) is required to purchase Mitsui's ordinary shares in an amount less than ¥1 million through the Mitsui Executives' Shareholding Association with his or her monthly remuneration.

The appropriateness of percentages of basic fixed remuneration, performance-related bonus, and stock- based compensation is verified each year by the Remuneration Committee, taking trends at other companies and other factors into consideration. The findings are reported to the Board of Directors.

The method used to determine the amount of performance-related remuneration is as follows. (The word "Directors" in (1) and (2) below refers to Directors excluding External Directors.)

1. Performance-relatedbonus
2. 1. Total amount paid in bonuses for Directors
      The performance-related bonus is calculated by the formula that is advised as appropriate by the Remuneration Committee and subsequently resolved at a Board of Directors meeting.
      For fiscal year ended March 31, 2020, total amount of bonus is calculated as follows:
      Total amount of bonus = (Consolidated profit for the period attributable to owners of the parent × 50% × 0.1%) + (Core operating cash flow × 50% × 0.1%)

However, the total amount shall not exceed ¥700 million. If the consolidated profit for the period attributable to owners of the parent is minus, i.e. "net loss", and/or core operating cash flow is minus, i.e. "cash outflow", then such item is set as 0 for the calculation.

Consolidated profit for the period attributable to owners of the parent and core operating cash flow are important indicators for Mitsui, and they are taken into consideration when determining the dividend policy.

1. Amount paid as individual bonuses
   The total amount calculated by the method shown in (a) above is distributed to each Director in proportion to the following points, which are assigned for each position. Amounts will be rounded to the nearest ¥10,000, however, if the total amount of the individual bonuses paid exceeds ¥700 million, each amount less than ¥10,000 will be rounded down.
   (Amount individually paid = total amount of bonus × position points / sum of position points) Points by position: Chairman/President (10), Executive Vice President (7), Senior Executive

- 28 -

Managing Officer (6), Executive Managing Officer (5)

Based on the composition of the Directors as of the date of the issuance of this report, the maximum amounts that may be paid for each position (at the limit of the total bonus amount of ¥700 million. ) are as follows:

Chairman/President = ¥700 million × 10 points / (10 points × 2 persons + 7 points × 2 persons + 6 points × 5 persons = 64 points) = ¥109.37 million

Executive Vice President = ¥700 million × 7 / 64 points = ¥76.56 million

Senior Executive Managing Officer = ¥700 million × 6 / 64 points = ¥65.62 million

1. Remuneration system of share performance-linked restricted stock
   The purpose of the remuneration system of share performance-linked restricted stock(hereinafter referred to as the "System") is to provide an additional incentive to Directors to achieve sustaining growth in Mitsui's medium to long-term performance and corporate value, and to foster a heightened sense of shared value with shareholders, by paying remuneration consisting of Mitsui's ordinary shares, with a certain transfer restriction period, to Directors (shares allocated under the System will be referred to below as the "Shares") in addition to basic fixed remuneration and performance-related bonus. This new compensation system is a share performance-linked remuneration system, since the number of Shares held by Directors at the end of a certain period (hereinafter referred to as the "number of Shares after valuation") would vary based on a comparison of the growth rates of Mitsui's stock price and the Tokyo Stock Price Index (TOPIX) over a specified period. By taking into account not only movements in Mitsui's stock price, but also the performance of Mitsui's stock compared with the stock market as a whole, the System is intended to give Directors a heightened awareness of the need to improve Mitsui's corporate value by amounts greater than the growth of the stock market.
2. 1. Payment method

Under the System, Directors would be granted an entitlement to receive monetary remuneration and will be issued Shares, whether newly issued as ordinary shares or disposed of, in exchange for the in-kind investment of their full entitlement. The amount of entitlements to be paid to each Director under the System will be determined by the Board of Directors based on deliberations by the Remuneration Committee, within the maximum limit approved at the General Meeting of Shareholders.

(b) Total number of shares to be issued or disposed of, paid-in amount per share

The total number of ordinary shares that would be newly issued or disposed of by Mitsui under the System would be no more than 500,000 per year (however, this number may be changed within reasonable limits if Mitsui's ordinary shares are affected by a stock split (including a free allotment of new ordinary shares in Mitsui) or a reverse stock split, or if other circumstances arise that require adjustments to the total number of Mitsui's ordinary shares that are issued or disposed of as restricted shares). The paid-in amount per Share will be decided by the Board of Directors based on the average daily closing price for Mitsui's ordinary shares on the Tokyo Stock Exchange (excluding days on which there is no closing price, the price will be rounded up to the nearest whole yen) in the three months immediately prior to the month containing the date on which the Board of Directors made a resolution concerning issuance or disposal of the shares

- 29 -

(hereinafter referred to as the "date of the Board of Directors' resolution"), within a range that is not especially advantageous to the Directors.

1. Details of share performance linkage conditions
   The number of shares after valuation would be determined as follows in linkage with the share performance, etc.
   If the growth rate of Mitsui's share price (*1) is equal to or greater than 150% of the growth rate of the Tokyo Stock Price Index (TOPIX) (*2), the number after valuation will be deemed to be the entire number of Shares issued (*3).
   If the growth rate of Mitsui's share price is lower than 150% of the TOPIX growth rate, the number of Shares after valuation will be a number calculated using the following formula, and the remainder of the Shares will be acquired by Mitsui without compensation at the end of the valuation period.

Number of shares after valuation = Number of Shares x	Mitsui's share price growth rate
TOPIX growth rate × 150%

= Number of Shares x

(A＋B) ÷ C

(D ÷ E) × 150%

(*1) This is the growth rate of Mitsui's share price during a valuation period defined as three years from the date of the Board of Directors' resolution (or the period to the date of retirement if a Director retires from their role as a director or managing officer of Mitsui before the elapse of three years. The same applies to (*2)). The growth rate will be specifically calculated as follows:

1. The average closing price of Mitsui's stock on the Tokyo Stock Exchange during the three months immediately prior to the month in which the final day of the valuation period falls
2. The total dividend per share for Mitsui's ordinary shares during the valuation period
3. The average closing price of Mitsui's stock on the Tokyo Stock Exchange during the three months immediately prior to the month in which the date of the Board of Directors' resolution falls

Growth rate of Mitsui's share price = (A+B) / C

(*2) This is the growth rate of the TOPIX during a period of three years from the date of the Board of Directors' resolution. It will be specifically calculated using the following formula.

1. The average TOPIX closing price on the Tokyo Stock Exchange during the three months immediately prior to the month in which the final day of the valuation period falls
2. The average TOPIX closing price on the Tokyo Stock Exchange during the three months immediately prior to the month in which the date of the Board of Directors' resolution falls
   TOPIX growth rate = D/E

(*3) Number of Shares = Entitlement to monetary compensation determined according to rank /

- 30 -

Paid-in amount per Share

1. Restriction on transfer
   Directors would be unable to transfer, pawn, or otherwise dispose of the Shares (hereinafter referred to as "Restriction on Disposal") for a period of 30 years from the pay-in date (hereinafter referred to as "Restriction on Transfer Period"). During the Restriction on Transfer Period, the Shares would be managed in dedicated accounts established with a securities company nominated by Mitsui.
2. Lifting of the Restriction on Disposal
   Irrespective of the provisions of (d) above, the Restriction on Disposal will be lifted if a Director retires as a director or managing officer of Mitsui before the end of the Restriction on Transfer Period.

(f) Grounds for acquisition without compensation (Clawback clause)

In addition to the condition that there will be an acquisition without compensation under the conditions for linkage to the share performance in (c) above, Mitsui will acquire without compensation all or part of the Shares during the Restriction on Transfer Period if a Director engages in actions that contravene laws and regulations, or on other grounds as stipulated in the agreement concluded between Mitsui and the Director.

(g) Procedures in the event of organizational restructuring, etc.

Mitsui would make reasonable adjustments to the number of Shares to be acquired without compensation or the time when the Restriction on Disposal will be lifted, by resolution of the Board of Directors, if Mitsui enters into a merger agreement resulting in the absorption of Mitsui, or a share swap agreement or share transfer plan under which Mitsui becomes a wholly owned subsidiary, or otherwise undertakes organizational restructuring, etc., during the Restriction on Transfer Period, pursuant to a resolution of a General Meeting of Shareholders (or a resolution of the Board of Directors in the case of a matter for which a resolution of a General Meeting of Shareholders is not required).

External Directors, who are separated from business execution, would receive only basic remuneration and would not be paid or given bonus or stock-based compensation linked to the stock price.

Directors are not paid retirement compensation.

As stated below, approval has been given through a resolution at a General Meeting of Shareholders that decisions about the maximum amount of Directors' remuneration and the maximum amounts for individual payments are taken within that limit by the Board of Directors.

- 36 -

is outlined below, together with a summary of the results.

< Evaluation Method > (Self-Evaluation)

In FYE March 2021, we evaluated the effectiveness of the Board of Directors through a self- evaluation process.

1. In January 2021, a survey ("the FYE 3/2021 survey") of all 14 directors and Audit & Supervisory Board members was carried out. Topics covered included the composition and operations of the Board of Directors as well as the content of deliberations.
2. On February 2, 2021, all external directors and external Audit & Supervisory Board members attended an external members meeting and shared their views on the effectiveness of the Board of Directors.
3. The results of the FYE 3/2021 survey and the external members meeting were discussed at a Governance Committee meeting held on February 24, 2021.
4. Following discussions at a Corporate Management Committee meeting held on March 29, 2021, the Board of Directors discussed the report from the Governance Committee at a meeting held on April 7, 2021 and then confirmed the effectiveness evaluation for FYE March 2021.

< Items in the Survey>

Questions in the FYE 3/2021 survey were divided into the following major categories. For each question, participants were asked to provide a score using a five-point scale. Space was also provided for free comments on each item.

< Effectiveness Improvement Initiatives in FYE March 2021 >

Based on the results of the evaluation of the effectiveness of the Board of Directors in FYE March 2020, the Board of Directors and Board of Directors Secretariat worked to address the following issues in FYE March 2021:

1. Further improvement of the operations of the Board of Directors
   In the past, 30-minutepre-briefing sessions were held for each agenda item. However, based on the results of the effectiveness evaluation survey last year, the pre-briefing sessions were extended and enhanced, with 45 minutes allocated for each item.

- 37 -

Furthermore, two free discussion sessions were held in FYE March 2021 in response to calls for additional sessions. Efforts were also made to enhance the information in materials provided at Board meetings, including cash flow and IRR trends for projects affected by impairment losses, as well as progress reports on projects approved by the Board of Directors.

In their responses to the FYE 3/2021 survey, the majority of external board members gave positive evaluations in relation to further improvements in the operations of the Board of Directors. There was a comment that the pre-briefings had been enhanced. Another comment was that there was room for improvement by leveling the number of agenda items, which varied according to the meeting.

1. Further enhancement of the effectiveness of the Board of Directors in relation to discussions on overall strategy
   Based on the results of the effectiveness evaluation for the previous fiscal year, two free discussion sessions were held during FYE March 2021. The themes for the first session in November 2020 were sustainable growth strategies that reflect ESG perspectives and Mitsui & Co.'s Materiality, and the DX strategy. The theme for the second session in March 2021 was the Mitsui Engagement Survey. Both directors and Audit & Supervisory Board members took part in lively discussions in these sessions.
   In the FYE 3/2021 survey, all external members provided positive evaluations of the free discussion sessions and expressed the view that these sessions again provided useful opportunities to talk about macroscopic themes, that they resulted in deeper discussions in the context of changes in social environment, and that there was more discussion about the company's broad strategic direction over the past year
2. Clarifications of the expected roles of advisory committees

One of the views expressed during the evaluation of the effectiveness of the Board of Directors in FYE March 2020 was that expectations concerning the roles of the advisory committees in relation to external members meetings, the Governance Committee, and the Board of Directors should be clarified. Following a meeting of the Governance Committee on May 14, 2020, it was decided at a meeting of the Board of Directors on June 10, 2020 to review the functions of the Governance Committee, Nomination Committee, and Remuneration Committee and redefine the expected roles for each of these committees, by revising the Mitsui & Co., Ltd. Corporate Governance and Internal Control Principles and the Internal Regulations on Advisory Committees to the Board of Directors.

In the FYE 3/2021 survey, most external members provided positive evaluations concerning the clarification of the expected roles of advisory committees. The majority view was that the revision of the rules had resulted in greater clarity.

< Outline of Evaluation Results >

The evaluation of the effectiveness of the Board of Directors in FYE March 2021 was

- 38 -

confirmed on the basis of the FYE 3/2021 survey, discussions at an external members meeting, and deliberations by the Governance Committee and Board of Directors.

It was confirmed that actions had been taken to improve effectiveness in FYE March 2021 by addressing the following issues.

• • Further improvement of the operations of the Board of Directors: Improvement of pre-briefing sessions, holding two free discussion sessions, enhancement of information provided in materials provided at Board meetings, including cash flow/IRR trends relating to projects affected by impairment losses, and the enhancement of progress reports on matters approved by the Board of Directors
  • Further enhancements to the effectiveness of the Board of Directors in relation to discussions about overall strategy: Two free discussion sessions on the themes outlined above in FYE March 2021
  • Clarification of the expected roles of advisory committees: Review of expected roles and functions through the revision of related rules
• Concerning the composition of the Board of Directors, the appointment of Director Ms. Egawa has further enhanced the diversity of the company by increasing the number of female external members.
• In relation to the operations of the Board of Directors, there was a qualitative improvement in the provision of information, including the early distribution of materials by the Board of Directors Secretariat.
• Sufficient time was provided for detailed pre-briefings in preparation for deliberations at Board meetings. There was strong awareness of corporate governance.
• During the COVID-19 crisis, meeting operations were characterized by thorough precautions against infection, with the result that it was possible to engage in free and open discussions.

Based on the preceding summary, the Board of Directors determined that an appropriate level of effectiveness was achieved in FYE March 2021. However, the Board of Directors also identified the following issue that will need to be addressed in order to achieve further improvements in effectiveness.

< Initiative toward Further Improvements in Effectiveness >

Ongoing consideration of the optimal number of directors, the ratio of internal to external members, the number of internal directors, and organizational design

The following views were expressed in the FYE 3/2021 survey, during discussions in the external members meeting, and at Governance Committee meetings.

• While the present number of directors appears to be necessary from a diversity perspective, the number is slightly too large for effective discussions.
• Concerning the ratio of internal to external directors, while the number of internal directors is high compared with the number of external directors, this is unavoidable given Mitsui
• • Co.'s business portfolio.
  • • 39 -

• The number of internal directors can be reduced. This is a matter that should be considered in the future.
• The Governance Committee should continue to consider organizational design, which is a fundamental aspect of governance.
• The Governance Committee should discuss issues such as the optimal number of directors, the ratio of internal to external directors, and organizational design, based on external benchmarks, such as trends in other companies.

There will be further deliberations and discussions, led by the Governance Committee, concerning the optimal number of directors, the ratio of internal to external directors, the number of internal directors, and organizational design. This process will take into account the views outlined above, and trends in other companies.

The Board of Directors will continue its efforts to achieve sustainable improvement in Mitsui & Co.'s corporate value by maintaining and enhancing its effectiveness, including the aspects outlined above, and by providing effective supervision of management.

• Pursuant to laws and regulations, the Articles of Incorporation and the provision of the Rules of the Audit & Supervisory Board, the Audit & Supervisory Board receives reports, deliberates and/or makes resolutions as to important matters in auditing. Regarding audits of consolidated group companies, because affiliated companies in Mitsui's consolidated group vary widely in terms of location, business areas, and growth stages, priority is given, during the formulation of audit policies, to checks concerning the assimilation of the Mitsui
• • Co. Group Conduct Guidelines as the foundation for the development and operation of internal control systems, and the performance of business activities in accordance with those guidelines.

This is followed by an exchange of opinions at the meeting of the Board of Directors. The results of this process are disseminated within the Company.
• Visits to the locations of frontline business activities and communication with the group employees who are active in those locations are an important part of our audit activities.

3. • Based on the order or approval of the President and Chief Executive Officer, for the purpose of contributing to the effective achievement of management goals, the Internal Auditing Division evaluates how internal control is present and functioning with emphasis on the effectiveness and efficiency of operations, the reliability of financial reporting, compliance with laws and regulations, as well as safeguarding of Company assets. The adequacy and effectiveness of each process in risk management, control (any action taken by the management toward the achievement of the established goals) and governance (processes and structures implemented by the management to inform, direct, manage and monitor the activities of the organization toward the achievement of its objectives) within each organizational unit shall also be evaluated, and suggestions and proposals shall be made for their improvement.
   • In order to ensure the independence and objectivity of internal audits, we have the Internal Auditing Division directly under the rule of the President and Chief Executive Officer. The composition of the personnel in the division as of March 31, 2020, is as follows: of a total of 77 people, which includes one General Manager, 40 internal auditors (including 24 re- employed retired contract employees), 24 members in charge of audits, and 12 staff members; 55 people are stationed in the Internal Auditing Division in the Head Office, 6 people are stationed in Internal Auditing Offices overseas, 3 people are stationed in the Internal Auditing Department within Business Supporting Units, and 13 people are stationed in subsidiaries.
   • In the regular audits which cover Mitsui, Overseas Offices, Overseas Trading Subsidiaries, and other subsidiaries, internal auditors carry out independent and objective evaluations, pursuant to the rules on internal audits, etc., with an emphasis on risk management, effectiveness of management and operations, compliance, and appropriate financial reporting. In addition, the following audits are implemented as internal audits: cross- organizational and cross-functional audits by target and item, such as issues involving multiple organizations and business processes or security trade control systems, and
   • • 43 -

extraordinary examinations to get a whole picture of such events that caused or could cause irregular economic losses or that jeopardized or could jeopardize the corporate trust, in order to identify the responsibility and recommend measures to clarify causes as well as to prevent recurrence. The Internal Auditing Division as an independent department compiles and checks the assessment of the entity-wide internal control regarding the credibility of financial reports, pursuant to the Financial Instruments and Exchange Act of Japan. The final results are reported to the below- mentioned J-SOX Committee.

1. • For each fiscal year, the internal auditing policy and the internal auditing plan go through the approval process by the President and Chief Executive Officer. Internal audits are implemented either with or without advance notice to the target organization. The internal auditors provide feedback on the results of the internal audit to the organization before preparing the internal audit report and carry out a full exchange of opinions on their suggestions. The audit results are reported to the President and Chief Executive Officer. The reports from the organization on the implementation status of improvements regarding the issues identified are requested and are reevaluated.
2. Auditing of financial statements
3. • For the year ended March 31, 2020, the certified public accountants executing audits on our financial statements are the following four people, who all belong to Deloitte Touche Tohmatsu LLC: Shuichi Morishige, Takashi Kitamura, Takenao Ohashi, and Yoshio Oka.

2. Framework for internal control and execution of business activities

• Ultimate responsibility for execution of business operations lies with the President and Chief Executive Officer. The President and Chief Executive Officer delegates authority to the Chief Operating Officers of the business units and regional business units, who, in turn, report to the President and Chief Executive Officer. The Corporate Management Committee is organized for deliberating the basic policies and important matters relating to the overall management. The Committee consists of the Chairman of the Board of Directors, President and Chief Executive Officer (the committee chair), the Directors in charge of Corporate Staff Units, and Representative Directors or Managing Officers nominated by the President and Chief Executive Officer. The Corporate Management Committee is held weekly in principle. Matters referred to the Corporate Management

Committee meeting are determined by the President and Chief Executive Officer, taking into consideration discussions among the Committee members.

• As mentioned above, the Internal Auditing Division, the division positioned directly under the President and Chief Executive Officer, examines the status of development and implementation of the internal control of Mitsui. With the delisting from NASDAQ in April 2011 and the termination of SEC registration in July 2011, Mitsui has implemented the internal control framework based on Japanese regulation from the year ended March 31, 2012. Even after the transition, Mitsui maintains its internal control system by positioning the internal control as the structure by which the management controls the executive body, aiming for: (1) "Improvement of effectiveness and efficiency of operations," (2) "Compliance with accounting standards and securing reliability of financial reporting," (3) "Compliance with laws, rules that are equivalent to the laws, and observance of management philosophy and company rules including all codes of conduct which reflect this philosophy," and (4) "The safeguarding of company assets;" and consists of: "control environment," "risk assessment," "control activities," "information and communication," "monitoring," and "response to IT." These objectives and components are as stated in the basic framework designated in "Standards and Practice Standards for Management Assessment and Audit concerning Internal Control Over Financial Reporting," issued by the advisory board to the Commissioner of the Financial Services Agency.
• Mitsui has established major committees pertaining to the execution of business and implementation of internal control as follows, and is taking measures to respond to a wide range of risks and forms of businesses, which continue to increase and diversify. The efforts made by the committees regarding execution of business activities and internal controls in the year ended March 31, 2020 are as follows:

	observer, develops, maintains, and improves the effectiveness of the
	compliance structure. In order to improve the awareness and knowledge of

	Mitsui distributed a handbook to all the employees, and conducted various
	compliance training sessions. Further, Mitsui established the With Integrity
	Month with the theme of "thinking about integrity", carried out various
	activities such as seminars, exchanges of opinions and information, and so

(d) Policy for determining audit fees

In determining audit fees, factors such as the auditing plan and the status of execution of duties by the auditor in the previous fiscal year are taken into account. In order to maintain and improve audit quality and efficient execution of audit, we check the audit process and divide roles between the auditor and the executive department as well as organizing the issues of the individual projects, which promotes transparency of the auditing hours and optimizes the amount of audit fees.

In addition, comparison of budget and actual results, analysis of fluctuation factors, studying further efficiency of audit and confirmation of its progress are carried out quarterly, all of which are discussed with the auditor in a timely manner.

The adequacy of audit fees is confirmed in accordance with the above policy, and the final approval is made with the consent of the Audit & Supervisory Board.

IV. Matters Related to the Internal Control System

1. Basic Views on Internal Control System and the Progress of System Development

Regarding internal control system and the related units, see II.2.2 "Framework for internal control and execution of business activities". In the construction of internal control processes, aiming to achieve the above mentioned objective of the internal control process - "Improvement of effectiveness and efficiency of operations," "Compliance with accounting standards and securing reliability of financial reporting," "Compliance with laws, rules that are equivalent to the laws, and observance of management philosophy and company rules including all codes of conduct which reflect this philosophy," and "The conservation of company assets" - the following systems are implemented.

1. Risk management system
   Risks arising from business activities are monitored and managed by Chief Operating Officers of business units and regional business units within their authorization delegated from the management. Risks associated with our business include quantitative risks such as credit risk, market risk, business risk arising from subsidiaries' businesses and country risk, as well as qualitative risks such as compliance risk and operational risk. Measures taken by each business unit to manage quantitative risks include setting of position limits and loss-cut limits as well as monitoring of positions by divisions with relevant expertise. For the management of qualitative risks, the business units are obligated to observe related internal regulations. When a business unit or a regional business unit takes risks greater than the scope of authority granted to the Chief Operating Officers, it is necessary to obtain approval of the Corporate Management Committee or a Representative Director in charge, or a Senior Managing Officer in charge, depending on the importance of the case, in accordance with the standards of the internal approval system.
   Furthermore, as stated in II.2.1. "Corporate Governance Structure" as committees responsible for business execution and the internal control system, organizations such as the Portfolio Management Committee, the Internal Controls Committee, the Sustainability Committee, and the Crisis Management Headquarters establish and develop the risk management structures and handle significant risks. These committees consist of Managing Officers and the General Managers of Corporate Staff Units. With respect to the risks in the fields they are in charge of, each division of the Corporate Staff Units is responsible for surveillance of the whole Company's positions, control within the prescribed range of their authority, and supporting the relevant Directors and Managing Officers.
2. Internal control over financial reporting
   As a result of the termination of the SEC registration, Mitsui implements the internal control framework as stipulated in the Financial Instruments and Exchange Act of Japan from the year ended March 2012. In addition to the Company-wide discipline, Mitsui has been conducting self-assessment by units subject to evaluation and testing by an independent division concerning the effectiveness of accounting and financial closing controls, IT controls, and business process level controls. After comprehensively assessing the above, Mitsui management confirmed that internal control over financial reporting is effective for the year ended March 31, 2020.
3. Internal controls regarding construction and management of information systems and information

security

"Information Technology (IT) policy" is declared as a basic policy for IT utilization to promote further awareness raising of employees and enhancement of IT governance. The important principles for our global group information strategy are formulated in line with the corporate management policy through the discussions at the Information Strategy Committee established pursuant to the "Rules of Information Strategy Committee." Under the system centered around the Information Strategy Committee, we are enhancing the system of internal control including management of various possible risks such as information leakage risks through maintenance of the following rules, necessary in light of development and operation of information systems and information security.

"Rules on Information System Management": rules on the process of procurement, introduction and operation of Information assets

"Rules on IT Security": code of conduct for the system supervisory divisions regarding IT security "Rules on Information Management": basic policies in terms of information risk management system and information management

"Rules on Protection of Personal Information": rules for the handling of personal information required for business execution (Applied only in Japan)

"Rules on Cyber Security Countermeasures": rules for preventive measures against cyber-attacks and emergency countermeasures in the event of incident

4. Compliance structure

In addition to the Compliance Committee, (see II.2.1 "Corporate Governance Structure"), chaired by the Chief Compliance Officer, Mitsui implements a compliance management system within the regular line of management at business division and department level. Further, Compliance Supervising Officers are designated at domestic and overseas units, branch offices and others.

Mitsui has set forth the "Business Conduct Guidelines for Employees and Officers of Mitsui & Co., Ltd." ("Guidelines") and has equivalent business conduct guidelines in place at its subsidiaries. Mitsui is striving to improve observance of the Guidelines through continuous monitoring and reviewing. Additionally, to further clarify our basic approach toward integrity and compliance on a global group basis, we have put together the "Mitsui & Co. Group Conduct Guidelines" to be shared by Mitsui & Co. Group companies. Please refer to the "Business Conduct Guidelines for Employees and Officers of Mitsui & Co., Ltd." or "Mitsui & Co. Group Conduct Guidelines" released on the Mitsui's website. Mitsui has a total of eight whistle-blowing avenues in place, including those involving an external attorney at law and a third-party providing hotline services. Pursuant to the Whistleblower Protection Act, Mitsui made it clear that a whistle-blower would not be subject to any recrimination or detrimental treatment by Mitsui as a result of whistle-blowing. Additionally, Mitsui makes sure that its domestic affiliated companies are also able to use the whistle-blowing avenues (external attorneys at law and a third-party providing hotline services) designated by Mitsui in order to (i) maintain a high standard of confidentiality and (ii) enable their employees to use these avenue without uneasiness. Mitsui's overseas offices and overseas affiliate companies also have whistle-blowing systems that were put in place considering applicable local laws and regional characteristics. Furthermore, Mitsui prohibits treating a whistleblower disadvantageously due to the reason of the whistleblowing itself, and will

- 56 -

thoroughly make this a known internal fact. Any cases of violation of compliance are handled strictly, including disciplinary actions in accordance with the Employment Regulations of Mitsui & Co., Ltd.

1. Specially Designated Business Management System
   In response to the DPF Incident, Mitsui established the "Specially Designated Business Management System" in April 2005. Under this system, internal review of four business domains which are "Environment-related business," "Medical, Healthcare and Bioethics-related businesses," "Businesses with subsidy," and "Business harboring other unusual reputation risks" is strengthened. When examining these matters, reports from the Sustainability Committee or the Environmental Societal Advisory Committee in which external experts participate as members, or opinions from other external experts will be obtained, as necessary. In addition, Mitsui appoints consultants with insights into environmental and social risk, human rights and utilize their advice for new and existing environment- related businesses as necessary.
2. Systems to secure appropriateness of operations within the corporate group
   In March 2006, Mitsui established the "Mitsui & Co., Ltd. Corporate Governance and Internal Control Principles" ("Principles"). In light of other laws and regulations and to the extent reasonable, Mitsui requires its subsidiaries to develop and operate internal controls based on these Principles, and for its equity accounted investees, Mitsui coordinates with other equity participants and encourages the equity accounted investees to develop and operate similar internal controls. For internal controls to secure reliability in financial reporting, see IV.1.2. "Internal control over financial reporting" above. In addition, from its officers and employees, Mitsui appoints supervising officers for its affiliated companies and has them engage in their duties based on the "Rules on Delegation of Authority for Supervising Officers for Affiliated Companies." Also, when Mitsui deploys full-time audit & supervisory board members in major affiliated companies, Mitsui selects personnel from the Internal Auditing Division rather than from related Business Units to enhance the independence of auditing.

2. Basic Views on Eliminating Anti-Social Forces

1. Mitsui reacts resolutely towards antisocial forces, and will not, as a matter of principle, conduct business with antisocial forces or with parties that have relations with antisocial forces.
2. Mitsui specifies the abovementioned principle in its "Business Conduct Guidelines", and makes this thoroughly known to its officers and employees. To reject antisocial forces, and to make this a company- wide stance, insertion of a clause within contracts rejecting antisocial forces is encouraged, and by placing a response unit, a system enabling routine coordination with external professionals, such as police and lawyers, is established.

1. Internal structure relating to timely disclosure to capital markets
2. 1. Mitsui has formulated principles and a basic policy and developed an internal structure relating to statutory disclosure, timely disclosure and other important disclosure materials and disclosing acts on an internal and external consolidated basis. We have also established the Disclosure Committee to examine highly urgent IR matters and formulate measures. The Disclosure Committee is a subordinate organization of the Corporate Management Committee. It is headed by the CFO and co-headed by CAO and CCO, and its members are the General Managers of the relevant corporate staff divisions. The Investor Relations Division, which acts as the secretariat for the Disclosure Committee, works with IR staff assigned to corporate staff divisions and business units to prepare drafts of disclosure documents and analyze points for discussion in response to directives from the Disclosure Committee.
   2. In its Corporate Disclosure Policy, Mitsui has defined the fundamental requirements and procedures for the disclosure of information that investors need to make appropriate decisions. This policy has been posted on the Company's website.
   3. Mitsui has established the Investor Relations Division as the unit responsible for disclosure to investors. This Division is in charge of administrative processes relating to timely disclosure and is responsible for the monitoring and management of facts, financial data, and other information that could have a material impact on investors' decisions, and for the accurate and timely disclosure of that information.
3. Facts that could have a material impact on investors' decisions
