Independent auditor's assurance report

To: the Annual General Meeting of Shareholders and the Supervisory Board of Koninklijke DSM N.V.

Independent Auditor’s Assurance Report 2016

Our conclusion

We have reviewed the sustainability information in the sections: ‘Nourishing the Base of the Pyramid’, ‘DSM and the Sustainable Development Goals’, ‘Strategy 2018: Driving Profitable Growth’, ‘How DSM creates value for its stakeholders’, ‘Brighter Living Solutions’, ‘Stakeholder engagement’, ‘People in 2016’, ‘Planet in 2016’, and ‘Sustainability statements’, as included in the Integrated Annual Report (hereafter: the Selected Sustainability Information) over the year 2016 of Koninklijke DSM N.V. (hereafter: Royal DSM), based in Heerlen, the Netherlands.

Based on our review, nothing has come to our attention to indicate that the Selected Sustainability Information is not presented, in all material respects, in accordance with the GRI Sustainability Reporting Standards and the internally developed criteria as described in the section Reporting policy .

The Selected Sustainability Information includes prospective information such as ambitions, strategy, plans, expectations and estimates. Inherently the actual future results may differ from these and are therefore uncertain. We do not provide any assurance on the assumptions and achievability of prospective information in the Selected Sustainability Information.

Basis for our conclusion

We have performed our review on the Selected Sustainability Information in accordance with Dutch law, including Dutch Standard 3810N: Assurance engagements relating to sustainability reports, which is a specified Dutch standard that is based on the International Standard on Assurance Engagements (ISAE) 3000: Assurance Engagements other than Audits or Reviews of Historical Financial Information.

This review engagement aims to obtain limited assurance. Our responsibilities under this standard are further described in the section ‘Our responsibilities for the review of the Selected Sustainability Information‘ below.

We are independent of Koninklijke DSM N.V. in accordance with the "Verordening inzake de onafhankelijkheid van accountants bij assurance-opdrachten" (ViO, Code of Ethics for Professional Accountants, a regulation with respect to independence) and other relevant independence regulations in the Netherlands. Furthermore, we have complied with the Verordening gedrags- en beroepsregels accountants (VGBA, Dutch Code of Ethics).

We believe that the review evidence we have obtained is sufficient and appropriate to provide a basis for our conclusion.

Report on the sustainability information included in other parts of the Integrated Annual Report

In addition to the Selected Sustainability Information and our assurance report thereon, the Integrated Annual Report contains other sustainability information.

Based on the following procedures performed, we conclude that the sustainability information included in other parts of the Integrated Annual Report is consistent with the Selected Sustainability Information and does not contain material misstatements.

We have read the other parts of the Integrated Annual Report. Based on our knowledge and understanding obtained through our review of the Selected Sustainability Information, we have considered whether the sustainability information included in other parts of the Integrated Annual Report contains material misstatements.

The scope of the procedures performed is substantially less than the scope of those performed in our review of the Selected Sustainability Information.

Responsibilities of Management for the Selected Sustainability Information

The Managing Board of Royal DSM is responsible for the preparation of the Selected Sustainability Information in accordance with the GRI Sustainability Reporting Standards and the internally developed criteria as described in the section Reporting policy .

The Managing Board is also responsible for such internal control as it determines is necessary to enable the preparation of the Selected Sustainability Information that is free from material misstatement, whether due to fraud or error.

Our responsibility for the review of the Selected Sustainability Information

Our responsibility is to plan and perform the review assignment in a manner that allows us to obtain sufficient and appropriate assurance evidence for our conclusion.

A review is aimed to obtain a limited level of assurance. Procedures performed to obtain a limited level of assurance are aimed at determining the plausibility of information and are less extensive than those in a reasonable assurance engagement. The level of assurance obtained in review engagements is therefore substantially less than the level of assurance obtained in an audit engagement.

We apply the "Nadere voorschriften accountantskantoren ter zake van assurance opdrachten (RA)" (Regulations for Audit Firms Regarding Assurance Engagements) and accordingly maintain a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.

Misstatements can arise from fraud or errors and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the decisions of users taken on the basis of the Selected Sustainability Information. The materiality affects the nature, timing and extent of our review procedures and the evaluation of the effect of identified misstatements on our conclusion.

We have exercised professional judgement and have maintained professional scepticism throughout the review, in accordance with the Dutch Standard 3810N, ethical requirements and independence requirements.

Our main procedures consisted of:

  • Performing an analysis of the external environment, obtaining an understanding of relevant social trends and issues, and of the organization’s business;
  • Evaluating the appropriateness of the reporting criteria and its consistent application, including the evaluation of the reasonableness of management’s estimates;
  • Evaluating the design and implementation of the reporting systems and processes related to the information in the Selected Sustainability Information;
  • Interviewing management and relevant staff at corporate and business group level responsible for the sustainability strategy and policy;
  • Interviewing relevant staff responsible for providing the Selected Sustainability Information, carrying out internal control procedures on the data and consolidating the data in the Selected Sustainability Information;
  • A limited number of visits to production sites to review the source data and the design and implementation of internal controls and validation procedures at local level;
  • An analytical review of the data and trends submitted for consolidation at corporate level;
  • Reviewing relevant data and evaluating internal and external documentation, based on limited sampling, to assess the accuracy of the information in the Selected Sustainability Information; and
  • Reviewing the results of procedures performed by the Corporate Operational Audit department of Royal DSM with respect to sustainability information.
