Independent Assurance Statement to Bayer AG Group Management
Introduction
We have reviewed Bayer Group Annual HSE Performance Data Collection Procedures and certain HR data collection procedures for the reporting period 2005 as described in the Bayer Sustainable Development 2005 (the ‘Report’). These subject matters are the responsibility of the Bayer AG Group Management, with whom the objective and terms of the engagement were agreed. We are responsible for expressing our conclusions based on the engagement.
We have based our approach on emerging best practice for independent assurance of Sustainability reporting, including isae 3000 (“Assurance Engagements other than Audits or Reviews of Historical Financial Information”), issued by the International Auditing and Assurance Standards Board (IAASB).

- 4. The implementation of the above subject matter 1 at nine reporting objects selected by us in consultation with Bayer AG: We visited Bayer Industry Services Leverkusen (Germany), Bayer HealthCare Elberfeld (Germany), Bayer HealthCare Berkeley (United States), Bayer MaterialScience Belford Roxo (Brazil), Bayer CropScience Belford Roxo (Brazil), and we engaged by phone and other means of communication with: Bayer Material-Science Bomlitz (Germany), Bayer MaterialScience Map Tha Phut (Thailand), Bayer CropScience Hangzhou (China), Bayer HealthCare Milan (Italy).
Procedures
Our objective was to achieve limited assurance. Based on an assessment of materiality and risk, we have gathered and evaluated evidence supporting the conformity with criteria for the subject matters described. This work included analytical procedures and interviews with management representatives and employees at Bayer AG Group headquarters in Leverkusen and, with respect to the HSE data procedures, at the nine reporting objects mentioned above. These were performed on a sample basis, as we deemed necessary in the circumstance, but no substantial testing was undertaken. Therefore, the assurance that we obtained from our evidence-gathering procedures is limited. We believe that our work provides an appropriate basis for our conclusion.
