The ICMS (VAT) credits that are reported in non-current assets arise mainly from acquisitions of property, plant and equipment, and intangible assets, and can be offset against taxes payable in the next 48 months. The transfer to non-current is made in accordance with management's best estimate of the amounts which will likely be realized after 2020. Credits of PIS/Pasep and Cofins generated by the acquisition of machinery and equipment can be offset immediately. The credits of PIS/Pasep and Cofins taxes recorded as non-current assets refer to the amounts paid for these taxes including ICMS tax in their basis of calculation. For more information see Note 10.
