Deferred income tax is measured using the balance sheet liability method in respect of temporary differences arising between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes on the basis of the intended use of the asset and settlement of the liability, respectively. Deferred tax assets are measured at the value at which the asset is expected to be realised, either by elimination in tax on future earnings or by set-off against deferred tax liabilities within the same legal tax entity.
Deferred tax is measured on the basis of the tax rules and tax rates that will be effective under the legislation at the balance sheet date when the deferred tax is expected to crystallise as current tax. Any changes in deferred tax due to changes to tax rates are recognised in the income statement or in equity if the deferred tax relates to items recognised in equity.
