4 Taxation The tax charge of £0.7 million (2003: £2.9 million) is based on an estimated effective tax rate on profit before goodwill amortisation and exceptionals for the year to 31 December 2004 of 21 per cent (2003: 25 per cent). The rate is lower than the standard UK corporation tax rate primarily due to the utilisation of losses and surplus ACT. Tax on exceptionals was a credit of £0.2 million (2003: charge of £0.2 million).
