(1) | CEMIG D was over contracted in 2017 and 2018 and the gain arising from the sale of the excess of energy in the spot market was provisionally passed through to customers by ANEEL in the tariff adjustments of 2018 and 2019, including the portion in excess of the limit of 105% of the regulatory load - thus reducing the tariff that was determined. To establish whether this is a voluntary over contracting, the Company considers that the portion above the regulatory limit will be recovered in the subsequent tariff adjustment. In 2020, ANEEL published the Dispatch 2,508, which set new amounts for distributors’ over contracting of 2017 in the amount of R$39, which was considered in the 2021 tariff process. Due to the administrative appeals submitted to ANEEL, the amounts of overcontracting had their values adjusted through ANEEL's dispatch 2.168, of 2022. With the publication of the order, and considering the current rules, the amount of R$219, pending transfer from 2017, will be considered in the next tariff process. Regarding the amount of R$27 related to the 2018 overcontracting, the Company continues to recognize the right and awaits publication of the respective order.
(2) | This is a financial component created for return to customers of the amounts that were invoiced to them but received by CEMIG from the Covid Account in 2020. These amounts was returned to customers in the tariff process of 2021, updated by the Selic rate, ensuring of neutrality.
