Individual Financial Statements Uncertain tax positions The amount of the estimated assets and liabilities recorded in connection with tax proceedings is the result of an assessment by the Company as at the date of the statement of financial position in relation to potential differences of understanding with the Tax Authorities. With regard to the measurement of uncertain tax positions, the Company takes into account the provisions of IFRIC 23 - “Un- certainty about income taxes”, namely in the measurement of risks and uncertainties in the definition of the best estimate of the expense required to settle the obligation, by weighing up all possible controlled outcomes and associated probabilities. Deferred tax: Deferred taxes are recognized in full using the liability method and calculated on temporary differences arising from the differ- ence between the tax base of assets and liabilities and their values in the financial statements. However, if deferred tax arises from the initial recognition of an asset or liability in a transaction that is not a business combination or that at the date of the transaction affects neither the accounting result nor the tax result, it is not accounted for. Deferred taxes are determined by the tax (and legal) rates enacted or substantially enacted at the date of the statement of financial position and which are expected to apply in the period in which the deferred tax asset is realized or the deferred tax liability is settled. The nominal base tax rate in Portugal is 19%. Deferred tax assets are recognized to the extent that it is probable that future taxable profits will be available to use the tempo- rary difference. The Company offsets deferred tax assets and deferred tax liabilities if, and only if: (a) it has a legally enforceable right to set off current tax assets against current tax liabilities; and b) the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same tax authority on either: (i) the same taxable entity; or (ii) different taxable entities that intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered. 536
