Editorial note: Paragraph 6 substituted by IFRS 3 with effect for business combinations for which the agreement date is on or after 31 March 2004, subject to further transitional provisions. Previously "The original IAS 12 did not refer explicitly to fair value adjustments made on a business combination. Such adjustments give rise to temporary differences and IAS 12 (revised) requires an enterprise to recognise the resulting deferred tax liability or (subject to the probability criterion for recognition) deferred tax asset with a corresponding effect on the determination of the amount of goodwill or negative goodwill. However, IAS 12 (revised) prohibits the recognition of deferred tax liabilities arising from goodwill itself (if amortisation of the goodwill is not deductible for tax purposes) and of deferred tax assets arising from negative goodwill that is treated as deferred income."
7    The original IAS 12 permitted, but did not require, an enterprise to recognise a deferred tax liability in respect of asset revaluations. IAS 12 (revised) requires an enterprise to recognise a deferred tax liability in respect of asset revaluations.
8    The tax consequences of recovering the carrying amount of certain assets or liabilities may depend on the manner of recovery or settlement, for example:
(a) in certain countries, capital gains are not taxed at the same rate as other taxable income; and
(b) in some countries, the amount that is deducted for tax purposes on sale of an asset is greater than the amount that may be deducted as depreciation.
The original IAS 12 gave no guidance on the measurement of deferred tax assets and liabilities in such cases. IAS 12 (revised) requires that the measurement of deferred tax liabilities and deferred tax assets should be based on the tax consequences that would follow from the manner in which the enterprise expects to recover or settle the carrying amount of its assets and liabilities.
9    The original IAS 12 did not state explicitly whether deferred tax assets and liabilities may be discounted. IAS 12 (revised) prohibits discounting of deferred tax assets and liabilities. Paragraph B16(i) of IFRS 3 Business Combinations prohibits discounting of deferred tax assets acquired and deferred tax liabilities assumed in a business combination.
