|1. | All of the financial information presented in this exhibit is unaudited.

|2. | The ratios for the years ended 31 March 2013 and 2012 been restated to reflect the Groups adoption of IFRS 11 Joint Arrangements and the revisions to IAS 19 Employee benefits, and includes
the Groups joint ventures using the equity accounting basis. The ratios for the years ended 31 March 2011 and 2010 have not been restated as it would involve unreasonable effort and expense. The ratios for the years ended 31 March 2011 and
2010 therefore include the Groups joint ventures on a proportionate consolidation basis, rather than on an equity accounting basis.
