Whistleblower System

General Information

Complying with statutory regulations and internal rules has top priority at CARIAD. We can only avoid damage to our company, our employees and business partners if rules and standards are respected. Consequently, misconduct must be recognized swiftly, processed and immediately remedied.

That calls for vigilance on the part of everyone along with a willingness to draw attention to possible Serious Regulatory Violations on the basis of Reasonable Suspicion. We also value information of this nature from business partners, customers and other third parties. Reports to the Central Investigation Office can be made at any time and in any language.

The Whistleblower System guarantees the greatest possible protection for whistleblowers and Persons Implicated. An investigation is only initiated after very careful examination of the facts and Reasonable Suspicion of a Regulatory Violation. There will be strict confidentiality and secrecy throughout the investigative process. Information will be reviewed fairly, promptly and in a sensitive manner.

Dr. Rainer Buchert and Thomas Rohrbach, the external ombudspersons appointed by the Volkswagen Group, act as special counsel to accept reports of potential statutory or internal violation of regulations or any other kind of harmful conduct in the Group, and to review these with respect to plausibility and substantiality. They consult with the whistleblower if necessary and if the identity of the whistleblower is known. Finally, they forward all the information that has been agreed with the whistleblower to the Central Investigation Office for further processing.

All information is treated as confidential and it is the whistleblower who decides whether he or she wishes to protect his or her identity vis-à-vis the Group. The ombudspersons appointed by the Group ensure that reports from whistleblowers who do not wish to be identified by the Company are forwarded to the Central Investigation Office anonymously.
