Dear Shareholder

Change of auditor

I am writing to advise you, as required by the Companies Act 2006, that the Company's auditor, Ernst & Young LLP, did not seek reappointment as auditor to the Company at the Annual General Meeting held today. I enclose a copy of the statement of circumstances in connection with Ernst & Young LLP ceasing to hold office which we are required to send to you under the Companies Act 2006.

PricewaterhouseCoopers LLP was appointed as auditor of the Company at the Annual General Meeting today and will be responsible for the audit of the Company's accounts for the year ended 31 December 2016. The Company carried out a formal tender process, at which a number of audit firms were considered, and it was recommended that PricewaterhouseCoopers LLP be appointed as the Company's independent auditor for the financial year commencing 1 January 2016.

Yours sincerely

Ian Cockerill Chairman
