[1] | The above table has been re-presented in order to separately disclose the deferred tax on ‘deferred compensation’ and ‘credit losses’ (both previously disclosed in ‘other short-term temporary differences’), to disaggregate the deferred tax on ‘application fees’ and ‘contract costs’, to present deferred tax on share-based compensation within ‘employee benefits’ (previously disclosed within ‘other short-term temporary differences’) and to disclose deferred taxes on ‘contract assets’ within ‘other short-term temporary differences’ (previously disclosed within ‘Other intangible assets and contract assets’).
