NOTES TO THE FINANCIAL STATEMENTS
YEAR ENDED 31 DECEMBER 2011
3 SIGNIFICANT ACCOUNTING POLICIES (CONT’D)
3.17 Income tax expense (cont’d)
Deferred tax is recognised in respect of temporary differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognised for the temporary
differences arising from the initial recognition of assets or liabilities in a transaction that is not a business combination and
that affects neither accounting nor taxable profit or loss, and temporary differences related to investments in subsidiaries
and jointly-controlled entities to the extent that it is probable that they will not reverse in the foreseeable future. In addition,
deferred tax is not recognised for taxable temporary differences arising on the initial recognition of goodwill. Deferred tax is
measured at the tax rates that are expected to be applied to the temporary differences when they reverse, based on the laws
that have been enacted or substantively enacted by the reporting date. Deferred tax assets and liabilities are offset if there
is a legally enforceable right to offset current tax liabilities and assets and they relate to income taxes levied by the same tax
authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a
net basis or their tax assets and liabilities will be realised simultaneously.
A deferred tax asset is recognised to the extent that it is probable that future taxable profits will be available against which
temporary differences can be utilised. Deferred tax assets are reviewed at each reporting date and are reduced to the extent
that it is no longer probable that the related tax benefit will be realised.
In the ordinary course of business, there are many transactions and calculations for which the ultimate tax treatment is
uncertain. Therefore, the Group recognises tax liabilities based on estimates of whether additional taxes and interest will be
due. These tax liabilities are recognised when the Group believes that certain positions may not be fully sustained upon review
by tax authorities, despite the Group’s belief that its tax return positions are supportable. The Group believes that its accruals
for tax liabilities are adequate for all open tax years based on its assessment of many factors including interpretations of tax
law and prior experience. This assessment relies on estimates and assumptions and may involve a series of multifaceted
judgements about future events. New information may become available that causes the Group to change its judgement
regarding the adequacy of existing tax liabilities, such changes to tax liabilities will impact tax expense in the period that such
a determination is made.
3.18 Earnings per share
The Group presents basic and diluted earnings per share data for its ordinary shares. Basic earnings per share is calculated
by dividing the profit or loss attributable to ordinary shareholders of the Company by the weighted average number of ordinary
shares outstanding during the year, adjusted for own shares held. Diluted earnings per share is determined by adjusting
the profit or loss attributable to ordinary shareholders and the weighted average number of ordinary shares outstanding,
adjusted for own shares held, for the effects of all dilutive potential ordinary shares, which comprise share options granted to
employees.
3.19 Segment reporting
An operating segment is a component of the Group that engages in business activities from which it may earn revenues and
incur expenses, including revenues and expenses that relate to transactions with any of the Group’s other components. All
operating segments’ operating results are reviewed regularly by the Group CEO to make decisions about resources to be
allocated to the segment and assess its performance, and for which discrete financial information is available.
Segment results that are reported to the Group CEO include items directly attributable to a segment as well as those
that can be allocated on a reasonable basis. Unallocated items comprise mainly corporate assets and liabilities, business
development costs and corporate expenses arising from group functions.
Segment capital expenditure is the total costs incurred during the year to acquire property, plant and equipment, and
intangible assets other than goodwill.
