所有遞延稅項負債及所有遞延稅項資產
（僅限於將來很可能取得應課稅溢利而
令該項資產得以運用的部分）均予確認。
容許確認由可予扣減暫時差異所產生的
遞延稅項資產的未來應課稅溢利包括其
將由目前的應課稅暫時性差異撥回的部
分，而此等應課稅暫時差異應由同一稅
務當局向同一應課稅單位徵收，並預期
在可予扣減暫時差異預期撥回的同一期
間內撥回或在由遞延稅項資產產生的稅
務虧損能轉回或轉入的期間內撥回。在
評定目前的應課稅暫時差異是否容許確
認由未經使用的稅務虧損及優惠所產生
的遞延稅項資產時採用上述相同的標
準，即該等暫時差異由同一稅務當局向
同一應課稅單位徵收，並預期在稅務虧
損或優惠能應用的期間內撥回方計算在
內。
應確認的遞延稅項數額是按照資產及負
債賬面值的預期變現或清償方式，以報
告期末採用或主要採用的稅率計算。遞
延稅項資產及負債均不作貼現計算。
本集團會在每個報告期末評估遞延稅項
資產的賬面值。如果不再可能取得足夠
的應課稅溢利以運用有關的稅務利益，
賬面金額則予以調低。如日後可能取得
足夠的應課稅溢利時，已扣減金額則予
以撥回。

(o) Income tax (Continued)
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 utilised, are
recognised. 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 utilised.
The amount of deferred tax recognised is measured based on
the expected manner of realisation or settlement of the
carrying amount of the assets and liabilities, using tax rates
enacted or substantively enacted at the end of the reporting
period. 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 profit will be
available to allow the related tax benefit to be utilised. Any
such reduction is reversed to the extent that it becomes
probable that sufficient taxable profit will be available.
