We are committed to the highest standards of openness, probity and accountability. In line with that commitment, we welcome suppliers, customers, and all other people with whom the Group engages in business relations to express any concerns they have about suspected illegal or illegitimate practices.

Internally, we encourage colleagues to speak up if they suspect wrongdoing of any kind. All queries about the interpretations and application of our Code of Conduct will be treated seriously and respectfully and assessed with confidentiality in a timely manner.
 
When making a report, this must be done in good faith and not for the purposes of spreading false information or making a report with malicious intent. Please provide as much information and be as specific as possible so we can follow up efficiently. It is our policy that retaliation is not permissible against any person raising a concern in good faith.
