Options to determine income tax liabilities   Under the first option income tax liabilities for the current and prior periods are measured at the amount expected to be paid to the taxation authorities, by applying the tax rate of 10% on the fiscal profit and loss. 50% of revenues derived from international freights are considered Paraguayan sourced (and therefore taxed) if carried between Paraguay and Argentina, Bolivia, Brazil or Uruguay. Alternatively, only 30% of revenues derived from international freights are considered Paraguayan sourced.
