Directors’ responsibilities

The directors are responsible for the selection, preparation and presentation of the selected sustainability information in accordance with the following criteria:

• For the subject matters in 1 and 2 (b): The GRI G4 guidelines; and
• For the subject matters in 2 (a): The amendment to the BBSEEC (2010) and related scorecard (2010).

This responsibility includes the identification of stakeholders and stakeholder requirements, material issues, for commitments with respect to sustainability performance and for the design, implementation and maintenance of internal control relevant to the preparation of the report that is free from material misstatement, whether due to fraud or error.

Our independence and quality control

We have complied with the code of ethics for professional accountants issued by the International Ethics Standards Board for Accountants, which includes independence and other requirements founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour.

In accordance with International Standard on Quality Control 1, KPMG Services Proprietary Limited maintains a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.

Our responsibility

Our responsibility is to express assurance conclusions on the selected sustainability information based on the work we have performed and the evidence we have obtained. We have 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. That standard requires that we plan and perform our engagement to obtain assurance about whether the selected sustainability information is free from material misstatement.

An assurance engagement in accordance with ISAE 3000 involves performing procedures to obtain evidence about the quantification of the selected sustainability information and related disclosures. The nature, timing and extent of procedures selected depend on the practitioner’s judgement, including the assessment of the risks of material misstatement, whether due to fraud or error. In making those risk assessments we considered internal control relevant to Implats’ preparation of the selected sustainability information. A limited assurance engagement is substantially less in scope than a reasonable assurance engagement in relation to both risk assessment procedures, including an understanding of internal control, and the procedures performed in response to the assessed risks. The procedures we performed were based on our professional judgement and included inquiries, observation of processes performed, inspection of documents, analytical procedures, evaluating the appropriateness of quantification methods and reporting policies, and agreeing or reconciling with underlying records.

Given the circumstances of the engagement, in performing the procedures listed above we:

• Interviewed management and senior executives to obtain an understanding of the internal control environment, risk assessment process and information systems relevant to the sustainability reporting process;
• Inspected documentation to corroborate the statements of management and senior executives in our interviews;
• Tested the processes and systems to generate, collate, aggregate, monitor and report the selected sustainability information, which included the following:
  • Performed control walkthroughs;
  • Inspected supporting documentation and performed analytical procedures on a sample basis to evaluate the data generation and reporting processes against the reporting criteria;
  • Undertook site visits to the Impala Rustenburg (mining, concentration and smelting), Impala Springs (refineries), Marula (mining and concentrating) and Zimplats (mining and concentration) operations; and
• Evaluated whether the selected sustainability information presented in the report is consistent with our overall knowledge and experience of sustainability management and performance at Implats.

The procedures performed in a limited assurance engagement vary in nature from, and are less in extent than for, a reasonable assurance engagement. As a result, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had we performed a reasonable assurance engagement. Accordingly, we do not express a reasonable assurance opinion on the matters described in 2 above.

Reasonable Assurance Opinion and Limited Assurance Conclusions

1.	On the selected key performance indicators on which we are required to express reasonable assurance
	In our opinion, the selected sustainability information set out in 1 above for the year ended 30 June 2015 is prepared, in all material respects, in accordance with GRI G4 guidelines.
2.	On the selected key performance indicators on which we are required to express limited assurance
	(a) Based on our work performed and the evidence we have obtained, nothing has come to our attention that causes us to believe that the selected sustainability information set out in 2(a) above for the year ended 30 June 2015 is not prepared, in all material respects, in compliance with the amendment to the BBSEEC (2010) and related scorecard (2010). (b) Based on our work performed and the evidence we have obtained, nothing has come to our attention that causes us to believe that the selected sustainability information set out in 2(b) above for the year ended 30 June 2015 is not prepared, in all material respects, in accordance with the GRI G4 guidelines.

Emphasis of matter

Without modifying our opinion or conclusions, we draw attention to our approach to reporting, which indicates that Implats has changed its calculation and definition of the LTIFR. In previous years the rate was calculated on the number of LTIs only which was changed to include both LTIs and restricted work injuries. For comparability purposes, prior year LTIFR data has been restated.

Other matters

The maintenance and integrity of the Implats’ website is the responsibility of Implats’ management. Our procedures did not involve consideration of these matters and, accordingly we accept no responsibility for any changes to either the information in the report or our independent assurance report that may have occurred since the initial date of presentation on the Implats’ website.

Our report does not extend to any disclosures or assertions relating to future performance plans and/or strategies disclosed in the report.

Restriction of liability

Our work has been undertaken to enable us to express the opinion and conclusions on the selected sustainability information to the directors of Implats in accordance with the terms of our engagement, and for no other purpose. We do not accept or assume liability to any party other than Implats, for our work, for this report, or for the opinion and conclusions we have reached.
