Goodwill arose on the acquisition of the Company’s subsidiary undertakings (note 10 ) in prior years. The Group tests goodwill for impairment annually and when there are indicators of impairment. 

The Group’s exploration and evaluation (“E&E”) assets at 31  December 2 010  consist entirely of capitalised expenditure in relation to the Group’s Ugandan ($ 1 7,28 3 ,86 3 ), Namibian ($697, 0 54) and SADR ($ 1 5 0 , 113 ) licences. These amounts have not been written off to the statement of comprehensive income as exploration expenses because commercial reserves have not yet been established or the determination process has not been completed.
