Deferred taxation
Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the reporting date.
Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the reporting date that are expected to apply to the reversal of the timing difference.
Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits.
Current and deferred tax assets and liabilities are not discounted.
