Relationship with auditors

6. Relationship with auditors

PricewaterhouseCoopers were appointed as auditors of the company on 8 February 1999, subsequently becoming PricewaterhouseCoopers LLP (PwC) in 2003.

The company has in place a formal policy on auditor independence and non-audit services, with which the external auditors are required to comply, to ensure that the independence of the auditors is not impaired by the nature of non-audit work. The policy stipulates work which is permitted or not permitted to be performed by the auditors, and provides for appropriate approval and oversight processes. As a further safeguard, PwC confirms in a formal report to the audit committee that processes to ensure compliance with this policy are in place and that these processes are monitored regularly. This report includes a statement that, in its opinion, PwC believes that the nature of its non-audit services has not impaired the audit of the company. Note 3 to the consolidated financial statements has a breakdown of non-audit services provided to the group by the auditors for the year under review.

The audit committee is satisfied that, for the period under review, the independence of the auditors has not been affected by the provision of non-audit services.

The committee has also implemented a formal system for the review of the effectiveness of the external auditors. This process involves the external auditors presenting to the committee their proposed audit strategy followed by the output of their initial discussions with management. At the audit committee meeting in May, the external auditors present the output of their detailed year-end work. In making its assessment of external auditor effectiveness, the committee reviews the audit engagement letters before signature by management, reviews the external auditors’ summary of group and subsidiary issues and management’s response to the summary, and conducts an overall review of the effectiveness of the external audit process and the external auditors. This review is facilitated by the use of templates that rate effectiveness across 18 critical criteria.
