The Committee judges our external auditors on the quality of their audit findings, management’s response and stakeholder feedback. No decisions are taken by the external auditor in relation to the design of internal controls and they do not perform a management role in any of the work that they undertake. Their audit and non-audit fees are set, monitored and reviewed throughout the year (see note 4). We ensure that our auditor engagement policy, which is reviewed annually and disclosed on our website, is adhered to when non-audit work is commissioned. The Committee recognises that in 2013/14 non-audit fees were impacted by one significant project, highlighted last year, that bridged the 2012/13 and 2013/14 financial years and the success of the Company’s EU Group Relief litigation, which resulted in advisory fees payable to PwC.. Fees for the latter were approved by the Committee in prior years as it was felt that PwC were best positioned to provide the services required given their deep understanding of the business, its culture and strategy, providing the most cost effective solution without comprising their independence. The Committee is mindful that these were exceptional items on which it had already reported and aims to maintain non-audit fees as a lower level going forward.
