In the year under review, we held five regular meetings of the entire Supervisory Board as well as one
extraordinary meeting by way of a conference call. Apart from two of these meetings which one Supervisory
Board member and one meeting which two Supervisory Board members were prevented from attending due to
other business appointments which could not be postponed, all members of the Supervisory Board attended the
meetings. The average attendance rate at meetings of the entire Supervisory Board was therefore just under
93%. All the committee meetings, with the exception of one Audit Committee meeting at which one member was
absent, were fully attended. The external auditor, KPMG AG Wirtschaftsprüfungsgesellschaft (KPMG), attended
all regular meetings of the Supervisory Board, inasfar as no Executive Board matters were dealt with. KPMG
also attended all meetings of the Audit Committee. The employee representatives held separate meetings to
prepare and discuss agenda items for all meetings of the entire Supervisory Board.
