(s) Income tax
Income tax for the year comprises current tax and movements in deferred tax assets and liabilities. Current tax
and movements in deferred tax assets and liabilities are recognized in profit or loss except to the extent that they
relate to business combination, or items recognized in other comprehensive income or directly in equity, in which
case the relevant amounts of tax are recognized in other comprehensive income or directly in equity, respectively.
Current tax is the expected tax payable on the taxable income for the year, using tax rates enacted or
substantively enacted at the balance sheet date, and any adjustment to tax payable in respect of previous years.
Deferred tax assets and liabilities arise from deductible and taxable temporary differences respectively, being the
differences between the carrying amounts of assets and liabilities for financial reporting purposes and their tax
bases. Deferred tax assets also arise from unused tax losses and unused tax credits.
Apart from certain limited exceptions, all deferred tax liabilities, and all deferred tax assets to the extent that it is
probable that future taxable profits will be available against which the asset can be utilized, are recognized.
Future taxable profits that may support the recognition of deferred tax assets arising from deductible temporary
differences include those that will arise from the reversal of existing taxable temporary differences, provided those
differences relate to the same taxation authority and the same taxable entity, and are expected to reverse either
in the same period as the expected reversal of the deductible temporary difference or in periods into which a tax
loss arising from the deferred tax asset can be carried back or forward. The same criteria are adopted when
determining whether existing taxable temporary differences support the recognition of deferred tax assets arising
from unused tax losses and credits, that is, those differences are taken into account if they relate to the same
taxation authority and the same taxable entity, and are expected to reverse in a period, or periods, in which the
tax loss or credit can be utilized.
The limited exceptions to recognition of deferred tax assets and liabilities are those temporary differences arising
from goodwill not deductible for tax purposes, the initial recognition of assets or liabilities that affect neither
accounting nor taxable profit (provided they are not part of a business combination), and temporary differences
relating to investments in subsidiaries to the extent that, in the case of taxable differences, the Group controls the
timing of the reversal and it is probable that the differences will not reverse in the foreseeable future, or in the
case of deductible differences, unless it is probable that they will reverse in the future.
The amount of deferred tax recognized is measured based on the expected manner of realization or settlement
of the carrying amount of the assets and liabilities, using tax rates enacted or substantively enacted at the
balance sheet date. Deferred tax assets and liabilities are not discounted.
The carrying amount of a deferred tax asset is reviewed at the end of each reporting period and is reduced to the
extent that it is no longer probable that sufficient taxable profits will be available to allow the related tax benefit to
be utilized. Any such reduction is reversed to the extent that it becomes probable that sufficient taxable profits
will be available.
