Sadia recognizes deferred tax assets and liabilities which do not expire under Brazilian law, arising from tax loss carry-forwards, temporary add-backs and other procedures. Sadia periodically reviews the deferred tax assets for recoverability and establishes a valuation allowance, as required, based on historical taxable income, projected future taxable income, and the expected timing of the reversals of existing temporary differences. In the event the Company or one of its subsidiaries operates at a loss or is unable to generate sufficient future taxable income, or if there is a material change in the actual effective tax rates or time period within which the underlying temporary differences become taxable or deductible, Sadia evaluates the need to establish a valuation allowance against all or a significant portion of the Company's deferred tax assets, resulting in an increase in the effective tax rate, thereby decreasing net income. If Sadia determines that it can realize a deferred tax in excess of its net recorded amount, it decreases the valuation allowance, thereby increasing net income. Significant management judgment is required in determining any valuation allowance. The principal uncertainty relates to the likelihood of future taxable income from the subsidiary that generated the deferred tax asset. A change in the Company's projections of profitability could result in the need to record a valuation allowance against deferred tax assets, resulting in a negative impact of future results.
