The main conditions related to the business between related parties are shown below:

 

(1)Refers to the sale of energy to the State Government of Minas Gerais considering that the price of energy is that defined by ANEEL through a resolution on the Company's annual tariff adjustment. In 2017, the Government of the State of Minas Gerais signed a Debt Acknowledgment Agreement (TARD) with CEMIG D for the payment of outstanding energy supply debts amounting to R$113, to be settled by November 2019. These receivables are guaranteed by the retention of dividends or interest on equity distributed to the State, in proportion to its indirect interest, for as long as the delinquency and/or default persists. CEMIG D obtained authorization on March 31, 2021 from the State Treasury Department of Minas Gerais to offset part of the ICMS to be collected against the debt that the State Government of Minas Gerais has with the Company under State Law 23,705/2020. The monthly amount to be offset is R$10.5, in 21 equal installments. Until December 31, 2022 all installments were compensated;
(2)This refers to the recalculation of the monetary correction of amounts related to AFAC returned to the State of Minas Gerais. These receivables are guaranteed by the retention of dividends or interest on equity distributed to the State, in proportion to its participation, while the delay and/or default persists. For further information see Note 11;
(3)The relationships between CEMIG and its investees are described in the investment Note 16;
(4)The sale and purchase of electricity between generators and distributors are carried out through auctions in the regulated contracting environment organized by the Federal Government. In the free contracting environment, in turn, they are carried out by means of auctions or direct contracting, according to the applicable legislation. Electricity transport operations, on the other hand, are carried out by the transmitters and result from the centralized operation of the National Interconnected System by the National System Operator (ONS);
(5)In June 2022, the provision relating to contractual obligations assumed by the Company in favor of the investee and the other shareholders was reversed. More details in Note 16;
(6)Refers to service agreement for the operation and maintenance of power plants and transmission networks;
(7)This refers to contractual obligations to the investee Aliança Geração corresponding to contingencies arising from events that occurred before the closing of the transaction that resulted in the contribution of assets by CEMIG and Vale S.A. in the capital of this investee. The total value of the shares is R$156 (R$149 at December 31, 2021), of which R$55 (R$52 at December 31, 2021) is attributable to CEMIG;
(8)A liability was recognized corresponding to the Company's interest in the capital of Hidrelétrica Itaocara due to its negative net worth (see Note 16);
(9)In January 2021, a final arbitration award was issued in favor of FIP Melbourne, and in August 2022 an agreement was reached between the parties to close the dispute, with the establishment of an updated compensation amount of R$200, settled on September 12, 2022 (see Note 16);
(10)Forluz's contracts are adjusted by the Broad National Consumer Price Index - IPCA of the Brazilian Institute of Geography and Statistics - IBGE, plus interest of 6% per year and will be amortized until 2031 (see Note 24);
(11)Company's contributions to the Pension Fund regarding the employees participating in the Mixed Plan and calculated over monthly remunerations in conformity with the Fund's regulation;
(12)Funds for the annual administrative funding of the Pension Fund in accordance with the specific legislation for the sector. The amounts are estimated as a percentage of the Company's payroll;
(13)Rental of the Company's administrative headquarters, valid until August 2024 (Júlio Soares building, which can be extended every 5 years, until 2034), annually adjusted by the IPCA, and its prices are reviewed every 60 months. On September 20, 2021, the rent contract was readjusted in 8.72%, corresponding to the accumulated IPCA of the last 12 months. On April 27, 2021 an amendment to the contract was signed with Forluz, due to the transfer of the facilities of the invested companies CEMIG SIM and Gasmig to the Júlio Soares building with the consequent reduction of the rent cost to CEMIG. On September 20, 2021, the rent contract was readjusted in 8.72%, corresponding to the accumulated IPCA of the last 12 months.;
(14)Post-employment obligations related to the employees' health and dental plan (see Note 24).
