We believe that accelerating management decision-making and smoothly executing business initiatives, while ensuring transparency throughout the process and eliminating illegal activities through mutual checks and balances, are essential elements of corporate governance.
To earn the trust of shareholders, investors, and other stakeholders, we believe that a dual structure is both effective and efficient. This consists of:
● strategic and prompt decision-making and oversight by the Board of Directors, which is well-versed in the challenges faced by both the automotive parts manufacturing industry and our company, and
● supervision and auditing by external directors and external auditors.
For this reason, we consider the structure of a company with an Audit & Supervisory Board to be appropriate. Under this framework, we will continue to strengthen our corporate governance.

Our Board of Directors consists of five directors. In addition to regular monthly meetings, extraordinary meetings are held as needed to deliberate and make decisions on important business operations. The Board also supervises the execution of duties by the Representative Director and Executive Directors through reports on the status of their activities.
Audit & Supervisory Board Members attend Board meetings and provide opinions as necessary.
To strengthen the function of the Board of Directors and ensure oversight from anindependent standpoint, we have appointed two Outside Directors. These Outside Directors provide valuable suggestions and advice based on their independent perspective, extensive management experience, and broad knowledge and insight.
Number of meetings held in FY2023: 20
To enhance the fairness, transparency, objectivity, and accountability of the Board of Directors in matters related to director nominations and compensation, we have voluntarily established a Nomination and Remuneration Committee. The committee is convened as necessary.
The committee consists of four directors, including two Outside Directors, with the Chairperson and the majority of members being independent Outside Directors.
The committee discusses matters such as proposals regarding the appointment and dismissal of directors, the compensation system for directors, and performance evaluations.
To earn and maintain the trust of shareholders and investors, our company has adopted an Audit & Supervisory Board system. We believe that this system—combining swift and strategic decision-making and oversight by the Board of Directors, who are well-versed in both the automotive parts manufacturing industry and our company’s management challenges, with supervision and auditing by Outside Directors and Outside Audit & Supervisory Board Members—is both effective and efficient.
The Audit & Supervisory Board consists of three members: one full-time member and two part-time members, all of whom are Outside Audit & Supervisory Board Members.
Each of the three members qualifies as an independent officer as defined by the Tokyo Stock Exchange.
They do more than simply audit legal compliance; acting from an independent and objective standpoint, they actively and assertively exercise their authority, ensuring a structure that enables proper judgment and action.
Our company has entrusted its accounting audit operations to KPMG AZSA LLC. The Accounting Auditor maintains close coordination with the Audit & Supervisory Board, providing reports on audit plans and results, and conducting necessary information and opinion exchanges throughout the fiscal year. These efforts aim to ensure audits are carried out both efficiently and effectively
The Executive Officers’ Committee consists of nine executive officers, including those who concurrently serve as directors. The committee deliberates and makes decisions on specific management issues related to business execution.
The Management Meeting is convened as necessary and consists of directors (excluding outside directors) and the presidents of each subsidiary. The meeting receives reports on the business plans and operational status of both domestic and overseas subsidiaries, enabling top management to monitor and follow up on business execution.
Under the activity slogan “Challenge to the Future,” our company is promoting the 15th Medium-Term Management Plan.
This plan sets forth the key theme of “rebuilding a management foundation that ensures sustainable profitability.”
To achieve this goal, we have established a system that enables prompt and objective decision-making on management issues from various perspectives. Accordingly, we appoint directors and auditors with consideration for diversity, including gender and international experience.

Effectiveness Evaluation of the Board of Director | March 2024 |
(1) Overview
Based on the results of the aforementioned questionnaire, the effectiveness of our Board of Directors was generally assessed to be appropriately maintained. Compared to the previous year, improvements were confirmed in the overall total of the items listed in the above table.
However, some items still show room for improvement. We recognize that these issues require continued examination and improvement on a regular basis moving forward.
(2) Items Showing Improvement

- Information disclosure to stakeholders, including timing, is being conducted appropriately.
- Improvements were seen in the planning of human resource development, including the establishment of a succession plan.
- Regarding the effectiveness of the Board of Directors:
- The number of directors, diversity, and the composition of internal and external members are generally appropriate.
(3) Items Needing Improvement
- Regarding the Board’s efforts on overall management:
- Implement strategic and planned information disclosure that includes non-financial information contributing to corporate value enhancement.
- Establish human resource development policies and frameworks to ensure consistent and continuous talent development.

Based on these evaluation results, focused deliberations will be conducted on the extracted issues. Priority will be given to items needing improvement, with corres ponding measures formulated and implemented. Specifically, meetings will be held a mong Board members to deepen discussions on management issues from diverse internal and external perspectives. By gathering each director’s views and expertise, improvement plans will be devised and advanced through the PDCA cycle.
Our company will continue to work on enhancing the effectiveness of the Board of Directors to achieve sustainable growth and medium- to long-term enhancement of corporate value.
The compensation system for directors is designed to function effectively as an incentive to sustainably enhance corporate value, linking remuneration to shareholder interests. The basic policy is to determine the appropriate level of individual director compensation based on their respective responsibilities.
Compensation for executive directors consists of fixed remuneration—“base salary” and “stock-based compensation”—and variable remuneration—“performance-linked bonuses” and “performance-based stock compensation.” For outside directors, who serve supervisory functions, fixed remuneration consisting of “base salary” and “stock-based compensation” is provided.
Base Salary | A fixed monthly compensation determined comprehensively by considering factors such as position, responsibilities, length of service, industry standards, the company’s performance, and employee salary levels. |
---|---|
Stock-Based Compensation | Designed to encourage directors to share not only the benefits of stock price appreciation but also the risks of stock price decline with shareholders, thereby fostering awareness that contributes to mid- to long-term performance improvement and corporate value enhancement. Points are granted for each fiscal year based on the Officer Stock Grant Regulations, which are approved by the Board of Directors. |
Performance-Linked Bonuses | Calculated by comprehensively evaluating the performance during the assessment period, position, and results of directors (excluding outside directors). The bonusamount is based on the achievement level against the consolidated operating profittarget for each fiscal year and is paid at a specified time. |
Performance-Based Stock Compensation | This system evaluates performance from two perspectives: the short-term business plan (STBP) performance evaluation coefficient and the medium-term business plan (MTBP) performance evaluation coefficient. Points are allocated for each fiscal year by multiplying the achievement rates against the short-term and medium-term tar gets by the respective weights assigned per position. Calculation method: Points granted = Position points × STBP weight × STBP performance evaluation coefficient + Position points × MTBP weight × MTBP performance evaluation coefficient |
Note 1: STBP refers to the Short-Term Business Plan
Executive Category | Total Compensation (Million JPY) | Total Compensation by Type (Million JPY) | Number of Eligible Executives (Persons) | |||
---|---|---|---|---|---|---|
Base Salary | Stock-Based Compensation | Performance-Linked Bonus | Performance-Based Stock Compensation | |||

監査役(うち社外監査役) | 23(23) | 23(23) | -(-) | -(-) | -(-) | 4(4) |
Additionally, as part of the performance-based stock compensation, we have introduced a "Stock Grant Trust (BBT※2)."
This system involves the acquisition of our company shares through a trust funded by monetary contributions made by the company. Shares are then granted to directors and others through this trust in accordance with the rules for stock-based compensation established by the company. Generally, the timing for directors and others to receive the shares is upon their retirement from the company.

Risk and Compliance Management System
The TBK Group has established a Risk and Compliance Committee, headed by the TBK P

as the prevention of maternity harassment, paternity harassment, sexual harassment, and power harassment.
Internal Whistleblowing System
The TBK Group has established an internal whistleblowing system for its domestic and overseas group companies with the purpose of preventing misconduct such as fraud, facilitating early detection and correction, and thereby strengthening complia
nce management. This system provides a proper mechanism for handling reports related to organizational or individual violations of laws and regulations within group companies in Japan and overseas.

Basic Philosophy
Recognizing that "ensuring the accuracy of financial reporting is an essential condition to gain the trust of stakeholders including shareholders and to expand and develop the business," we strive for the continuous improvement of internal controls. To embody this philosophy, we undertake the following:
- Conduct internal control activities to enhance stakeholders’ trust in the financial reporting of the Company Group.
- Effectively utilize the internal control management system to prevent financial fraud and errors, and to continuously improve.
- Comply with laws, regulations, and internal rules related to internal controls.
- Develop and implement action plans based on the internal control policy, carry out concrete deployment, and conduct regular reviews.
The scope of application includes company-wide internal controls, IT general controls, and the following business processes:
Target Business Processes
(1)Sales Process
(2)Purchasing Process
(3)Manufacturing Cost Management Process
(4) Inventory Management Process
(5)Closing and Financial Reporting Process
(6) IT-related Business Processing Controls
Based on the “Basic Policy of the Internal Control System,” our company promotes the establishment of key management foundations such as legal compliance, risk management, information management, and audit systems to realize fair and efficient business operations. Additionally, we ontinuously review and improve internal controls in response to social demands and changes in laws and regulations, aiming to conduct highly transparent corporate activities and secure trust from stakeholders.
Basic Concept of Information Security
- We protect the information assets we hold from various threats, maintaining their confidentiality, integrity, and availability.
- Each employee shares a common understanding of the importance of information security and ensures that no security issues arise.
- We implement personnel security measures, physical security measures, technical security measures, and operational security measures.
- We strictly comply with relevant laws, regulations, and rules.
Security measures for PCs and servers using tools (EDR*) that detect suspicious behavior within devices Our domestic group has implemented EDR, applying it not only to internal business terminals but also to servers and manufacturing line terminals, thereby strengthening security measures. *EDR: A system designed not to prevent attacks or intrusions on devices but to detect threats that were not prevented.
Network security measures based on Zero Trust Security
To adapt to changes in working styles and system configurations, we operate a SASE (Secure Access Service Edge) platform, an integrated security model, under the concept of “Zero Trust Security,” which verifies the security of all communications.
Unauthorized access prevention measures using multi-factor authentication*
*Multi-factor authentication (MFA) requires users to provide multiple verificatio n factors to gain access, enhancing security.
In our domestic group, multi-factor authentication (MFA) has been implemented for
access to email systems and internal information-sharing systems. This mechanism prevents unauthorized access even if attackers obtain passwords, thereby strengthening the protection of critical information. At the same time, it balances strict authentication with user convenience, providing an environment where employees can use systems with peace of mind.
*By combining passwords with one-time passwords generated on smartphones or biometric authentication, this system significantly reduces the risk of unauthorized access and impersonation.
