The Annual Report and Accounts, which incorporate the Notice of Annual General Meeting, will remain on the website at least until the Annual Report and Accounts for the following year are made available. In line with good environmental policies the Board believes that it is not in the Company's or the shareholders' best interests to incur the costs or create the adverse environmental impact of unnecessarily printing and distributing hard copies of these documents, and we ask that you please refrain from printing these documents unless absolutely necessary.
