The Board meets regularly and is responsible for strategy, performance, approval of major capital projects and the framework of internal controls. To enable the Board to discharge its duties, all Directors receive appropriate and timely information. Briefing papers are distributed to all Directors in advance of Board meetings, and all Directors have access to the advice and services of the Company Secretary, who is responsible for ensuring that Board procedures are followed and that applicable rules and regulations are complied with. The Articles of Association provide that at each annual general meeting one third of the Directors who are subject to retirement by rotation shall retire from office, and they may then be re-appointed.
