(1)

Reversal of the over contracting amounts passed on to consumers in the 2018 and 2019 tariff adjustments because they were previously recognized by ANEEL as involuntary over contracting, made possible by the publication of the involuntariness orders, recognizing over contracting as voluntary. Regarding the amount constituted in the period, there is a high volume of surplus energy, mainly due to the growing increase in the energy injected by MMGD facilities, settled at a low PLD.

(2)

In addition to the transfers between sectoral financial assets and liabilities, there was a transfer of R$1,550 to the "Other assets" group.
