Responsibilities of the Directors

Harmony’s Directors are responsible for the preparation and presentation of the Identified Sustainability Information, as incorporated in the 2010 SD Report, in accordance with their internally defined procedures and for maintaining adequate records and internal controls that are designed to support the reporting process.

Responsibility of the independent assurance provider

Our responsibility is to conduct a limited assurance engagement and, based on our assurance procedures, report our conclusions to the Directors.

We conducted our engagement in accordance with the International Standard on Assurance Engagements (ISAE) 3000, Assurance engagements other than audits or reviews of historical financial information issued by the International Auditing and Assurance Standards Board. This Standard requires that we comply with ethical requirements and plan and perform the assurance engagement to obtain assurance on the Identified Sustainability Information as per the terms of our engagement.

Summary of work performed

Our procedures included examination, on a test basis, of evidence relevant to the Identified Sustainability Information. It also included an assessment of the significant estimates and judgements made by the Directors in the preparation of the Identified Sustainability Information.

Our work consisted of:

• reviewing processes that Harmony have in place for determining the Identified Sustainability Information included in the SD Report;
• obtaining an understanding of the systems used to generate, aggregate and report the Identified Sustainability Information at the sampled operations;
• conducting interviews with management at the sampled operations and at corporate head office;
• evaluating the data generation and reporting processes against the reporting criteria;
• performing key controls testing and testing the accuracy of data reported on a sample basis; and
• reviewing the consistency between the Identified Sustainability Information and related statements in Harmony’s Sustainable Development.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our limited assurance conclusion. Harmony’s internal corporate reporting criteria and the Global Reporting Initiative’s (GRI) new generation (G3) guidelines were applied for evaluating the Identified Sustainability Information. The “Glossary of terms and acronyms” provides detail on the applied definitions of the Identified Sustainability Information.

Inherent limitations

Non-financial data is subject to more inherent limitations than financial data, given both the nature and the methods used for determining, calculating, sampling or estimating such data. Qualitative interpretations of relevance, materiality and the accuracy of data are subject to individual assumptions and judgements.

Conversion factors used to derive CO₂ emissions and energy used from fuel and electricity consumed, is based upon information and factors derived by independent third parties. Our assurance work has not included an examination of the derivation of those factors and other third party information.

We have not carried out any work on data reported for prior reporting periods nor in respect of future projections and targets. We have not conducted any work outside of the agreed scope and therefore restrict our opinion to the Identified Sustainability Information.

Conclusion

Based on our work performed, nothing has come to our attention that causes us to believe that the Identified Sustainability Information selected for limited assurance has not been prepared, in all material respects, in accordance with the defined reporting criteria.
