To the Executive Board of Merck KGaA, Darmstadt, Germany

We were engaged to provide assurance on the sustainability information relating to ‘Materiality analysis’ and ‘Stakeholder dialogue’ as well as on the indicators in the chapter ‘Facts and figures’, including explanatory notes, in the online ‘Merck KGaA, Darmstadt, Germany Corporate Responsibility Report 2014’ (further ‘the Report’) for the business year 2014 of Merck KGaA, Darmstadt, Germany. The Executive Board is responsible for the appropriateness of the determination and presentation of the sustainability information in the Report in accordance with the reporting criteria. This responsibility includes the conception, implementation and maintenance of systems and processes for ensuring adherence to sustainability reporting principles when determining material report contents. Our responsibility is to issue an assurance report on the selected sustainability information, including the explanatory notes, published in the Report.


Our assurance engagement was designed to provide limited assurance on whether the following selected sustainability information for the business year 2014, including the explanatory notes, are presented, in all material respects, in accordance with the reporting criteria:

In the chapter ‘Facts and figures - Indicators’ the GRI G4 Specific Standard Disclosures on:

  • Economics

  • ‘Identified Material Aspects and Boundaries’ GRI G4-17 to 23
