The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal to the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are addressed below. (a) Income taxes and deferred taxation Significant judgement is required in determining the provision for income tax. There are many transactions and calculations for which the ultimate determination is uncertain. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such difference will impact the current tax and deferred tax assets and liabilities in the period in which such determination is made. Deferred tax assets relating to certain temporary differences and tax losses are recognised when management considers it is probable that future taxable profit will be available against which the temporary differences or tax losses can be utilised. The outcome of their actual utilisation may be different.
