We believe that key to earn the trust of stakeholders pertains to not only the HOYA Group´s observance of laws and regulations but also all Group employees´ fair and faithful conduct with high ethical standards. Based on this recognition, in 1997 we formulated the HOYA Business Conduct Guidelines which clearly indicates the standards of conduct for each and every employee.
The HOYA Business Conduct Guidelines are consistently revised in order to reflect the formulation, revision and abolition of laws and changes in society. Since the Guidelines were adopted, we confirm the Guidelines in training and workplace activities and utilize it for raising awareness of employees.
Also, overseas Group companies use a regional version of the HOYA Business Conduct Guidelines formulated in accordance with national and regional laws and customs in order to strive for enhancement of compliance.

Internal Control System

In addition to striving to further strengthen corporate governance, the HOYA Group also works toward the development of sound internal control systems with the objective of ensuring appropriate and efficient business management. Each business division and facility develops and improves the control environment, evaluates and responds to risk, and verifies and improves the control processes to ensure that the control systems that operate within each division and facility are the most appropriate for their operating environment. The head of each business division has managerial authority and is responsible for improving the business results. Each head is also obligated to seek to further improve internal control systems, with the objectives of maintaining compliance, effectiveness and efficiency of work practices, the reliability of financial reporting and the integrity of management assets. The Audit Department at HOYA Group Headquarters is responsible for the regular auditing and verification of administrative processes for each division and business office from an independent standpoint. It conducts operational audits, checks that internal control systems are functioning as they should, ensures that there is no dishonesty, and checks for areas for potential improvement. Problems that come to light as a result of audit procedures become the subject of a recommendation for improvement. Particularly important matters are reported to the Audit Committee and the Board of Directors, as well as to the executive officers. The executive officers decide upon and issue directives for speedy, appropriate responses.

HOYA Business Conduct Guidelines

To achieve the best results from internal control systems, it is essential that all employees performing duties for an organization work to foster greater awareness. The HOYA Group has established a set of Business Conduct Guidelines that clarify the guiding principles under which each employee should perform his or her duties, with resolute adherence to professional ethics. The Group also conducts a wide range of employee education activities to foster awareness of regulations and rules.

Enlightenment of HOYA Business Conduct Guidelines

The HOYA Group distributes HOYA Business Conduct Guidelines to the Group employees in order for each one of them to be able to apply those principles to the specific situations that arise in day-to-day business. Every employee in Japan reads through, understands and confirms the willingness to comply with its principles before signing a confirmation letter once a year. Overseas Group companies use a regional version of the HOYA Business Conduct Guidelines translated in local languages and formulated in accordance with national and regional laws and customs as a guide for everyday practice.

HOYA Help Line

In 2003 the HOYA Group implemented another initiative, the HOYA Help Line, as an internal reporting and consultation system for the Group. If there is an act that contravenes the law or the HOYA Business Conduct Guidelines, the HOYA Help Line is intended to enable early identification of the problem and quick reporting to top management, while protecting the informer, which enables timely and appropriate action to be taken on the issue. This system helps to preserve the integrity of the HOYA Group as a whole. The HOYA Help Line has two types of points of contact; one is “HHL” a dedicated section within the HOYA Group Headquarters and the other is an outside legal counsel. The system is designed to preserve anonymity and works to maintain the system´s functional effectiveness.

Enhancement of compliance

To enlighten and enhance compliance, we continue to publish posters and leaflet as well as to disseminate the information for the HOYA Group. To raise awareness, we introduce self-check test and FAQ as well as internal cases in the Group intranet and on the bulletin boards. We also display posters and distribute leaflet in our workplaces for better understanding and reconfirmation of the importance of compliance.

Internal Control Reporting System (J-Sox)

HOYA has completed the creation of a system for visualizing the status of internal controls over financial reporting for the Group´s key operating divisions. The Group has also created a framework for evaluation of these controls. In the fiscal year under review, the Group will begin conducting verifications of the effectiveness of internal controls. Items that do not conform or for which internal controls are found to be inappropriate or insufficient will be improved, and HOYA will continue its efforts to ensure the reliability of financial reporting.

Training programs

HOYA provides themed training programs for antitrust laws and others that reflect each division´s business environment to help employees reconfirm and enhance compliance.

HOYA Anti-Bribery and Anti-Corruption Policy

Based on the HOYA Code of Conduct, the HOYA Group has established this Global Policy to strengthen its anti-bribery and anti-corruption initiatives. The policy outlines specific measures, including rules, management systems and education, to prevent bribery and corruption, and we believe that acting in accordance with this policy will further enhance the trust of our stakeholders. We will continue to make group-wide efforts.
