Prior year numbers have been restated, as far as practicable, to reflect the revisions to the activities in the different segments that took place during the year, as disclosed in note 3 to the financial statements. The analysis between British Gas residential, Centrica Business Services and Centrica energy management group is not available for 1998 and 1999.
Prior years have been restated for changes in accounting policies. 1998 and 1999 were restated on implementation of FRS 12 Provisions, contingent liabilities and contingent assets in 1999. On implementation in 2001 of FRS 19 Deferred Tax and mark to market accounting for energy trading derivative financial instruments, values for 2000 were restated but not those for 1998 and 1999.
Goldfish Bank included certain financial service activities under the British Gas brand until 1 April 2000. From that date, the activities transferred to AA personal finance.
