[1] | The variation in provisions for legal claims occurred due to the review of the assessment of the Company’s legal advisors, mainly in civil claims. The details of the actions are shown in Note 30.
[2] | The contracts between Petrobras and Compagás were offset by the volume of 55,770,890 m³, disregarding the difference in gas pricing between the contracts (NE 12.1). However, the parties have not reached a consensus to this date, and the amount of R$15,688 remains in dispute. In view of the compensation made by Petrobras and the uncertainty in the reimbursement of the difference in Brazilian reais of the referred Assignment, impairment was recorded for this amount until the end of the transaction.
