Our definition of an independent Director is one who is independent of management and free from any business or other relationship that could materially interfere with the exercise of independent judgement. It is the Board's view that except for Peter Mattick, each of its non-executive Directors is independent. Materiality for these purposes is determined on both quantitative and qualitative bases. There is a majority of independent non-executive Directors on the Board of the Company.

Access to independent professional advice

Guidelines are in place which provide for each Director to have the right to seek independent professional advice at the Company's expense subject to the prior approval of the Chairman.

External auditor's appointment

The Company and Audit Committee policy is to appoint external auditors who clearly demonstrate quality and independence. Our independent external auditors are PricewaterhouseCoopers. They are required to confirm that they have maintained their independence as part of their review of the half-year and full year results. PricewaterhouseCoopers were appointed in November 2013. Our auditors will be available to answer questions at each Annual General Meeting.
