The Audit Committee monitors the accounting process and the effectiveness of the internal control system, the risk management system and the internal auditing system. In addition, the Audit Committee deals with compliance issues.

The Mediation Committee formed according to Section 27 (3) MitbestG submits to the Supervisory Board a slate of candidates for Executive Board membership if these have not received the required two-third majority of Supervisory Board member votes in the first ballot.
