Review work performed
We conducted our review in accordance with guidance contained in Bulletin 1999/4 issued by the Auditing Practices Board for use in the UK. A review consists principally of making enquiries of Group management and applying analytical procedures to the financial information and underlying financial data and, based thereon, assessing whether the accounting policies and presentation have been consistently applied unless otherwise disclosed. A review excludes audit procedures such as tests of controls and verification of assets, liabilities and transactions. It is substantially less in scope than an audit performed in accordance with International Statements on Auditing (UK and Ireland) and therefore provides a lower level of assurance than an audit. Accordingly, we do not express an audit opinion on the financial information.
