The composition and functioning of the Committees are de fi ned by those statutory and regulatory provisions applicable to limited liability companies, the Company’s Articles of Association, and the rules of procedure of the Board of Directors.

The Chairman of each Committee may ask the Chief Executive Of fi cer and, where applicable, any Deputy CEO(s) to attend Committee meetings. This also applies to the Chairman of the Board of Directors, where he or she is not a member of the Committee in question.
