Basis for the Assurance Conclusion

We conducted our assurance engagement in accordance with the International Standard on Assurance Engagements (ISAE) 3000 (Revised): “Assurance Engagements Other Than Audits or Reviews of Historical Financial Information”, issued by the International Auditing and Assurance Standards Board (IAASB).

The procedures performed in a limited assurance engagement vary in nature and timing from, and are less in extent than for, a reasonable assurance engagement. Consequently, the level of assurance obtained is substantially lower than the assurance that would have been obtained had a reasonable assurance engagement been performed.

Our responsibilities under ISAE 3000 (Revised) are further described in section “German Public Auditor’s Responsibilities for the Assurance Engagement on the Combined Non-Financial Reporting”.

We are independent of the entity in accordance with the requirements of European law and German commercial and professional law, and we have fulfilled our other German professional responsibilities in accordance with these requirements. Our audit firm has applied the requirements of the IDW Quality Management Standards and of the International Standard on Quality Management (ISQM) 1. We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our assurance conclusion.
