The tax expense comprises current and deferred tax. Current tax The current income tax charge is determined in accordance with the relevant tax law regulations in respect of the taxable profit. Income tax liabilities/assets represent the amounts expected to be paid to/received from the tax authorities at the end of the reporting period. Deferred taxes Deferred taxes are recognised for temporary differences, as well as for unused tax losses. Deferred tax assets are recognised only when their recovery is considered probable. At the end of the reporting period unrecognized deferred tax assets are re-assessed. A previously unrecognized deferred tax asset is recognised to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered. Deferred tax is not accounted for if it arises from the initial recognition of an asset or liability in a transaction that is not a business combination and at the time of the transaction, affects neither accounting nor taxable profit nor loss. Deferred tax assets and liabilities are not discounted. Deferred income tax is calculated using the enacted or substantially enacted tax rates at the end of the reporting period.
