Risk and other factors

US GAAP and IFRS

The presentation of the Group’s accounts can also be affected by changes to generally accepted accounting policies, such as the adoption of International Accounting Standards in 2005/06. Both US GAAP and IFRS continue to be revised and subject to new interpretations. Such changes may influence the results reported and the valuation of the Group’s shares. For guidance independent external professional advice is available to management and the Audit Committee. The results of the Group are influenced by the application of US GAAP and IFRS in areas involving significant subjectivity and judgment, such as tax and pensions.

If the Group became a domestic issuer for SEC purposes, it would be required in due course to produce results using US GAAP as well as IFRS. This may result in confusion in interpreting the Group’s results.
