ANNUAL REPORT ‘12
NOTES TO THE FINANCIAL STATEMENTS
194
Deferred taxes are shown as a whole, using the liability method for temporal differences derived from the difference
between the tax basis of the assets and liabilities and their values in the consolidated financial statements. However,
if the deferred tax emerges from the initial showing of an asset or liability in a transaction that is not a merger,
which on the date of the transaction does not affect either the accounting results or the result for tax purpose,
it is not included in the accounts.
The deferred taxes are determined by the tax rates (and laws) decreed or substantially decreed on the date of the
balance sheet and that are expected to be applied during the period when the asset deferred tax will be realised or
the liability deferred tax will be liquidated.
Asset deferred taxes are shown insofar as it is likely that the future taxable profits will be available for use in the
temporal difference.
Income tax is shown in the income statement, except when related to items that are shown directly in the equity.
