(3) | The deferral of PIS/Pasep and Cofins taxes related to the interest revenue arising from the financing component in contract asset and to the revenue of construction and upgrade associated with the transmission concession contract, whose consideration will be received in at least twelve months after the reporting period. For more information, see note 2.8 and 15.
The amounts of PIS/Pasep and Cofins taxes to be refunded to customers refer to the credits to be received by the Company following the inclusion of the ICMS value added tax within the taxable amount for calculation of those taxes. According note 9 (a), the Company recognized, in 2019, its right to offsetting of amounts unduly paid for the 10 years prior to the action being filed, with monetary updating by the Selic rate, due to the final judgment – against which there is no appeal – on the Ordinary Action, in favor of the Company. The Company has a liability corresponding to the credits to be reimbursed to its customers, which comprises the period of the last 10 years, from June 2009 to May 2019, net of PIS/Pasep and Cofins taxes over monetary updating. The definitive criteria for the refunding of PIS/Pasep and Cofins taxes to customers are pending, awaiting conclusion of discussions with Aneel and the mechanisms and criteria for reimbursement, when actual offsetting of the tax credits takes place. On August 18, 2020, Aneel ratified the inclusion into the tariff readjustment for 2020 of a negative financial component of R$714, in effect from August 19, 2020 to May 27, 2021 – this corresponds to the release of the escrow funds deposited in court following final judgment in the Company’s favor against which there is no further appeal. For more information see Note 14.5.
