Review Report on the Condensed Interim Consolidated Financial Statements

Management Board’s Responsibility for the Condensed Interim Consolidated Financial Statements

The preparation of the condensed interim consolidated financial statements in accordance with the IFRS applicable to interim financial reporting as adopted by the EU is the responsibility of the entity’s Management Board. The Management Board is also responsible for such internal control as the Management Board determines is necessary to enable the preparation of condensed interim consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Practitioner’s Responsibility for the Review of the Condensed Interim Consolidated Financial Statements

Our responsibility is to express a conclusion on the condensed interim consolidated financial statements based on our review. We conducted our review in accordance with the German generally accepted standards for the review of financial statements promulgated by the Institut der Wirtschaftsprüfer (IDW) as well as in supplementary compliance with the International Standard on Review Engagements “Engagements to Review Historical Financial Statements” (ISRE 2400 (revised)). Those standards require that we plan and perform the review in compliance with professional standards such that we can preclude through critical evaluation, with limited assurance, that the condensed interim consolidated financial statements have not been prepared, in all material respects, in accordance with the IFRS applicable to interim financial reporting as adopted by the EU.

A review of the condensed interim consolidated financial statements in accordance with the German generally accepted standards for the review of financial statements promulgated by the Institut der Wirtschaftsprüfer (IDW) as well as in supplementary compliance with ISRE 2400 (revised) is a limited assurance engagement. A review is limited primarily to inquiries of personnel of the entity and analytical procedures and therefore does not provide the assurance attainable in a financial statement audit. Since, in accordance with our engagement, we have not performed a financial statement audit, we cannot issue an auditor’s report.

Conclusion on the Condensed Interim Consolidated Financial Statements

Based on our review, no matters have come to our attention that cause us to presume that the condensed interim consolidated financial statements have not been prepared, in all material respects, in accordance with the IFRS applicable to interim financial reporting as adopted by the EU.
