(1) In 2022, a provision was recorded as a result of Law 14385/22, which determined the fully destination, for the benefit of consumers, of the amounts subject to repeal of debt by the distributors, related to the exclusion of ICMS from the PIS/Pasep and Cofins calculation basis. The amount refers to the period from the 11th year onwards, counted retroactively from the date of the final and unappealable decision in the lawsuit, net of the portion included in the 2022 and 2023 Annual Tariff Adjustments.
