- Work from which the external auditors are prohibited. The Audit Committee concluded that it was in the best interests of the Company for the external auditors to provide a number of non-audit services during the year due to their experience, expertise, and knowledge of the Group’s operation. Auditor objectivity and independence was achieved by ensuring that personnel involved in the non-audit work were not involved in the audit, and by ensuring that management took responsibility for all decisions made. PwC follows its own ethical guidelines and continually reviews its audit team to ensure its independence is not compromised. PwC’s independence is also considered by the Audit Committee regularly. The fees paid to the auditors in the year are disclosed in the Group financial statements.
