Initiatives to prevent bribery and corruption
Our group complies with all applicable laws and regulations, including those applicable to our customers' industries, and conducts fair and open transactions. In order to build healthy and favorable business relationships with our business partners, we will conduct gift-giving and entertainment with good sense and moderation, have established "Anti-Bribery Guidelines," have been made known to our executives and employees, and we conduct training on "Anti-Bribery" and other topics.
We have also established a reporting system for cases where entertainment or gifts are received from business partners, and we confirm that entertainment and gifts are provided within the bounds of good sense, that excessive entertainment or gifts are not received, and that business partners are not requesting the provision of benefits.
Concerns about corrupt practices, including bribery, can be reported and discussed through the internal reporting system.
Basic Policy
In order to thoroughly prevent bribery of domestic and international public officials and private sector parties, the DTS Group complies with the anti-bribery laws of each country in which it conducts business. In addition, we comply with all relevant laws and regulations, including those applicable to our customers' industries, and conduct fair and open transactions.
Scope of application
This policy applies to all officers and employees of the DTS Group. In addition, we have formulated the "DTS Supply Chain Responsible Business Conduct Guidelines" for our business partners, and we require them to understand, support, and practice our anti-bribery and anti-corruption efforts, working to prevent bribery and corruption throughout our business value chain.
Legal compliance
The DTS Group complies with the Japanese Unfair Competition Prevention Act, the US FCPA (Foreign Corrupt Practices Act), the UK Bribery Act 2010, the Chinese Criminal Code on Bribery, and other laws and regulations related to bribery and corrupt practices in each country.
Promotion Structure
We have clearly defined policies and rules regarding bribery prevention, and these are implemented primarily by the relevant departments. We have established a system where employees can promptly consult with their superiors or compliance officers if they have any doubts or questions. We regularly review policies and rules and revise them as necessary.
Prohibition of Bribery
The DTS Group strictly prohibits the offering, promising, providing, or receiving of improper benefits, whether directly or indirectly. Providing benefits through intermediaries or small payments for the purpose of facilitating procedures (facilitation payments) also constitutes bribery and is not tolerated as a general rule.
Handling of entertainment and gifts
The DTS Group generally prohibits the giving of entertainment and gifts to public officials, etc., and will not provide improper benefits to foreign public officials or business partners. In addition, we will establish appropriate standards and a reporting system for the receipt of entertainment and gifts from private parties as well, ensuring transparency and fairness, thereby promoting sound and trustworthy business activities.
Record keeping
To ensure transparency regarding entertainment and gifts, we manage records in accordance with anti-bribery guidelines. Receipt of gifts and entertainment is reported in accordance with prescribed procedures, and records are kept appropriately. This prevents excessive entertainment and inappropriate gift-giving and ensures the effectiveness of internal controls.
Donations and political contributions
Donations are drafted and approved appropriately in accordance with the rules of authority. Political donations are strictly compliant with laws and regulations, and transparency is ensured in accordance with internal procedures. If there are any questions, we consult with the relevant department and make decisions based on the latest external regulations.
- Political donations
We do not make political contributions.
Response to bribery and corruption
Our group does not tolerate any corrupt practices, including bribery, and will deal strictly with any violations. Bribery not only has a serious impact on a company's credibility and business continuity, but may also result in criminal liability and disciplinary action against those involved.
Dealing with business partners
Our group considers the prevention of bribery and corruption to be an issue that must be addressed throughout the entire supply chain, and we require our business partners, such as agents and subcontractors, to comply with our policies and relevant laws and regulations.
In conducting business, we will maintain a fair and transparent relationship and implement appropriate management and supervision to prevent the provision of unfair benefits or any actions that could give rise to suspicion of such benefits.
Internal reporting system (helpline)
In order to maintain sound and highly transparent corporate operations, the Group has established an internal reporting system (helpline) to detect violations of laws and regulations or acts contrary to corporate ethics at an early stage and deal with them appropriately. We have clearly defined a mechanism for protecting whistleblowers so that they do not suffer any disadvantage, and have created an environment in which they can use the system with peace of mind. We also accept anonymous reports, and the privacy of received information and personal information is fully protected under strict management.
Furthermore, we have set up a reporting hotline that can be used by group companies both in Japan and overseas, and have put in place a system that can respond in multiple languages, including English, Chinese, and Vietnamese. The existence of the reporting system and contact information for reporting are made known to employees through compliance training, and we are working to ensure that everyone can use the system appropriately.
DTS values ​​a corporate culture that encourages speaking up and aims to conduct business activities in a fair and honest manner.
