1. Basic Views

Our Group (hereinafter, collectively referred to as "the Group") considers corporate governance to be a key management mechanism for transparent, fair, prompt and resolute decision-making, and all Group companies are thus actively committed to improving corporate governance. As part of the Group's corporate governance, we are enhancing internal controls by proactively undertaking activities to advance compliance and risk management. Furthermore, we are enhancing and strengthening the management oversight functions of the Board of Directors and the audit functions of our Audit and Supervisory Committee. These steps will enable us to construct a transparent corporate governance system worthy of the trust of shareholders and other stakeholders and fulfill our corporate social responsibilities, and will help us improve our corporate value through sustained growth.

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

The Company implements each of the Corporate Governance Code's principles. (Full Compliance)

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

[Supplementary Principle 1.2.4 Exercise of Shareholder Rights at General Meeting of Shareholders]

The Company recognizes the need to create an environment that facilitates the smooth exercise of voting rights by institutional investors and overseas investors based on the composition of our own shareholders. The Company participates in a voting rights electronic exercise platform and promptly discloses English-language versions of Convocation Notices on TDnet and the Company's website at the same time as the Japanese-language versions.

[Principle 1.4 Cross-Shareholdings] 1. Policy on Cross-Shareholding

Our basic policy when engaging in investment for purposes other than pure investment is to verify the need for holding each individual stock from the perspective of its importance in implementing our business strategy and strengthening business alliances for the sake of improving our corporate value over the medium-to-long term. Meanwhile, the Company is aiming to reduce cross-shareholdings by appropriately selling those shares deemed unnecessary. Furthermore, the Company verifies the benefits and risks of holding listed shares for cross-shareholding purposes along with profitability in light of capital costs and other factors at the Board of Directors on an annual basis. Regarding the shares that are deemed necessary to be held by the Company, we disclose the purpose of such holding in Securities Reports.

2. Standards for Exercising Voting Rights

We exercise voting rights for these shares based on careful examination of individual agenda items from a corporate governance and social responsibility perspective as well as our approach to medium-to-long term improvement of the corporate value of the companies whose shares we hold and shareholder returns.

[Principle 1.7 Related Party Transactions]

When the Company engages in transactions with its Directors, the Company submits material facts relating to such

transactions to the Board of Directors for resolution, in accordance with standards for the submission of agenda items to the Board of Directors stipulated under the Rules of the Board of Directors. The Company provides all of its officers and the presidents of its major subsidiaries with a questionnaire concerning the existence of related-party transactions annually, thereby establishing a system to manage related-party transactions. In the case of important transactions between the Company and a major shareholder, we also require a resolution at the Board of Directors in accordance with standards for the submission of agenda items to the Board of Directors.

[Supplementary Principle 2.4.1 Ensuring Diversity, Including Active Participation of Women]

The Company is proceeding with the establishment of a system for fostering human resources focused on the development of human resources who can contribute to strengthening competitiveness and who are capable of conducting cross-cultural management for continuous growth and development. We are also creating a work environment and corporate culture in which diverse human resources can exercise their individual abilities amidst a trend of advancing globalization and diversification of values. In particular, in Japan, we consider it important to further promote female employees to managerial positions and are continuously implementing initiatives for facilitating the active participation of women in various workplace, aiming to increase the ratio of female employees in managerial positions to over 3% as the medium-term target in FY2027. Also aiming at 30% or more female members of the Board of Directors, we will realize the reflection of diverse opinions in the management. We disclose the Company's views and targets on the promotion of core human resources, including the promotion of female, non- Japanese and midcareer employees, as well as our policies for human resources development and the progress on the development of internal environment in the Company's Integrated Reports and on our website.

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

The Company is not subject to this principle as it does not adopt a defined benefit corporate pension plan. The Company has adopted an optional defined contribution pension plan as a means of forming assets after the retirement of employees. Under the defined contribution pension plan system, the Company is not responsible for retirement benefits as participants manage their contributions by themselves, so the Company has no investment risk.

The policy on determining the amount and the calculation method of remuneration for the Company's Senior Management and Directors, as described below, was resolved at the 947th meeting of the Company's Board of Directors held on February 26, 2021, taking into account the deliberations and reports by the Nomination/Remuneration Committee.

a. Policy on determining the amount and the calculation method of remuneration of the Senior Management and Directors and the method of determination

The Group upholds the corporate philosophy that "We contribute to the progression of society through innovative technology, with respect for both individuals and the global environment." Based on this philosophy, the Company has designed its Senior Management and Directors' remuneration system in a way that clarifies management responsibilities while also providing an incentive toward improving our corporate value over the medium-to-long term through sustained growth.

The remuneration for Inside Directors who are not Audit and Supervisory Committee Members and Senior Executive Officers is comprised of (1) a fixed monthly remuneration, (2) bonuses, as performance-linked remuneration, and (3) stock remuneration, at a ratio of roughly 50%, 35%, and 15%, respectively. The monthly remuneration for Inside Directors who are not Audit and Supervisory Committee Members is calculated within the limits approved by the general meeting of shareholders, based on the remuneration table provided in the internal regulations according to their job positions, with comprehensive consideration given to their responsibilities and other reference points such as external remuneration survey data. The Board of Directors has resolved to delegate the determination of individual remuneration to the President & CEO (Takeshi Aoki, mainly in charge of overseeing overall business execution), who is best qualified to make a comprehensive assessment of each recipient including their job performance, taking account of the deliberations and reports by the Nomination/Remuneration Committee on individual payment amounts. In addition, bonuses are paid in cash once a year after the end of each fiscal year within the total amount that is calculated based on a prescribed formula approved by the general meeting of shareholders. The amount allocated to each individual is determined based on the degree of contribution by each Inside Director who is not an Audit and Supervisory Committee Member to the Company's operations. The Board of Directors has resolved to delegate the determination of individual bonuses to the President & CEO, who is best qualified to make a final assessment on the degree of contribution by each recipient to the Company's operating results, taking account of the deliberations and reports by the Nomination/Remuneration Committee on individual payment amounts.

The monthly remuneration for Senior Executive Officers is calculated based on the remuneration table provided in internal regulations according to their positions, with comprehensive consideration given to the appropriate balance with Inside Directors who are not Audit and Supervisory Committee Members, evaluation of their individual job performance, and other reference points such as external remuneration survey data. The Board of Directors has resolved to delegate the determination of such remuneration to the President & CEO, taking account of the deliberations and reports by the Nomination/Remuneration Committee. In addition, bonuses are calculated based on the degree of contribution by each Senior Executive Officer to the Company's operating results. The Board of Directors has resolved to delegate the determination of such bonuses to the President & CEO, taking account of the deliberations and reports by the Nomination/Remuneration Committee.

Outside Directors who are not Audit and Supervisory Committee Members and Members of the Audit and Supervisory Committee, being in positions independent of business execution, are only paid fixed remuneration of a certain amount within the limits approved by the general meeting of shareholders.
