Corporate Governance
Basic stance
The purpose of the corporate governance of the Nidec Group is to become a conscientious and principled company that earns society’s trust and to increase our corporate value sustainably, based on the
motto “High growth, high profit, and high share price.” To this end, we maintain and enhance our internal control, thereby running our business more healthily and efficiently. Furthermore, we disclose
information appropriately to increase the transparency of the Company’s business operations. We are also committed to ensuring the independence and diversity of the Board of Directors by taking into
account, among others, the balance of the knowledge, experience and qualifications of the Board of Directors as a whole and the number of its members, based on its diversity in gender, career history,
age, etc. and on Nidec’s business scale.
In order to ensure the effectiveness of the Board of Directors’ Meeting, it is important to incorporate a new perspective with independence and objectivity from a third party. If a third party perspective
is not introduced, there is a risk that the function of the Board of Directors’ Meeting will not improve or may even slow down. In addition, if the effectiveness of the Nomination Committee and
Remuneration Committee is not improved and fairness, transparency and objectivity are not ensured, we recognize that this will have a significant impact on the loss of public trust due to legal
and compliance violations, as well as on the improvement of corporate value and the sustainability of management.
Based on the understanding that corporate governance is one of the highest-priority issues for our sustainable growth and medium- to long-term improvement in corporate value, we will make efforts to
enhance the relevant systems.

Questionnaire survey on the effectiveness of the Board of Directors (efforts and evaluation)
Efforts made in FY2024 to ensure effectiveness
In order to deepen non-executive directors' understanding of the Company’s business activities and enhance deliberations at Board of Directors meetings, we implemented the following measures:
- ─ Held pre-briefing sessions and informal meetings on a regular basis.
- ─ Shared, at the Board of Directors meetings, key questions and opinions raised at pre-briefing sessions.
- ─ Clearly described the anticipated risks and their countermeasures in the reference materials for Board of Directors meetings.
- ─ Disseminated important agenda items and minutes of the meetings of the Audit and Supervisory Committee and other committees to outside directors.
FY2024 evaluation results
-
①In general, the following points were evaluated.
- ─ The Board of Directors is functioning sufficiently.
- ─ The composition of the Board of Directors (number of members, the ratio of inside and outside directors), and frequency and duration of meetings are appropriate.
- ─ Communication regarding the convening of the Board of Directors meetings is accurate and smooth, and the secretariat’s operations are effective.
- ─ Opportunities to request additional information to clarify any uncertainties regarding deliberation items are secured.
- ─ Information is provided to outside directors to ensure that they fully understand the Company's corporate philosophy, business environment, business strategies, and business challenges.
- ② In the third-party evaluation (by an external legal firm), which was introduced in FY2021, the Company’s Board of Directors received high praise for both its composition and operation. In particular, it was confirmed that there was a well-established system for the Board of Directors to conduct robust discussions and fulfill its supervisory functions and that preliminary briefing sessions and informal meetings contributed greatly to improving the effectiveness of the Board of Directors. As issues to be addressed, it was pointed out that, as in FY2023, there should be further discussion on the medium- to long-term management strategies and the analysis of the causes of failure to meet targets.

Target
Materiality

Actions
Nidec Group companies’ corporate governance
Nidec Group companies act based on the Nidec Corporation’s business philosophies and policies, and are part of the Nidec Corporation’s internal control system. Nidec Corporation dispatches and seconds its executives and employees to its consolidated subsidiaries. The companies respectively consider the opinions of experts and others, and discuss sufficiently before making executive decisions based on each company’s situation, to secure its independency.
Cross-shareholding
Policy for cross-shareholding
Nidec holds shares in the companies that Nidec has relationships with in terms of trading and cooperation in its business and other areas, when it judges that such shareholding contributes to the company’s corporate value expansion through stabilization of its business from a medium-to-long-term perspective by maintaining and strengthening its relationship with those companies. Nidec assesses its cross-held shares individually at the Board of Directors meeting every year, on not only qualitative aspects such as the purpose of the shareholding, but also on quantitative aspects such as the benefits that can accrue through the shareholding from the perspective of economic rationality. According to the results of the assessment, Nidec intends to reduce the number of shares it holds if the cross-held shares are not expected to bring significant benefits.
Criteria for exercising voting rights for cross-shareholding
With regard to the exercise of voting rights in relation to cross-shareholdings, Nidec makes comprehensive decisions to vote for or against individual proposals to serve the investees’ sustainable growth from the perspective of whether appropriate governance and compliance structures are in place at investee companies.
(Basic views on exercising voting rights)
With regard to the individual proposals submitted to the shareholders’ meetings of the companies Nidec invests in, Nidec decides to vote for or against after confirming the following points: whether the
proposals suit the purposes of the shareholding which are to maintain and strengthen the trade and cooperation relationships through medium-to-long- term investment; and particularly, whether there are
any circumstances that might lead to undermining of the shareholders’ value due to the restructuring of organizations, including asset transfer and mergers. Nidec opposes all proposals that are considered
to violate the law or constitute antisocial behavior, in all circumstances.
