Supervisory Board – self-assessment

Every three years, the Supervisory Board uses a comprehensive questionnaire (currently comprising 41 questions) to review the efficiency of its activities, the organization and the conduct of meetings including their preparation, information provided by the Board of Management and other aspects (self-assessment according to recommendation D.12 of the German Corporate Governance Code). The questionnaire must be completed by every Supervisory Board member, and the result is discussed anonymously in plenary session. Based on the outcome, the Supervisory Board then decides where and how processes must be changed, or the Supervisory Board determines that no changes are required. The last review took place in the summer of 2024, during which it was found that the concept of the sustainability expert was met with strong approval, even though coordination and interface management are challenging. The latter needs to establish itself and should be reviewed on an ongoing basis. In summary, it can be concluded from the 2024 self-assessment that the work and organization of the Supervisory Board are viewed positively by its members.
