As specified by the grantor (Aneel) in Normative Resolution 615/2014, the valuation reports that support the amounts in relation to the residual value of the plants, previously operated by Cemig GT, that were included in Lot D and for the Volta Grande plant have been submitted to the grantor. The Company does not expect any losses in the realization of these amounts. On December 31, 2020, investments made after the Jaguara, São Simão and Miranda plants came into operation, in the amounts of R$174, R$3 and R$23, respectively, are recorded as concession financial assets, and the determination of the final amounts to be received by the Company is in discussion with Aneel (the grantor). The Company does not expect losses in realization of these amounts. In 2019, Publicc Hearing 003/2019 was opened to obtain inputs on improvement of the criteria and procedures for calculation of investments in assets returnable to the Grantor, not yet amortized or not depreciated, of generation concessions (whether extended or not), under Law 12,783/2013 and a Technical Note 096/2019 related to this matter was published on September 30, 2019. However the Normative Resolution has not yet been voted on by the Council of Aneel.

14.4 | Account for compensation of variation of parcel A items (CVA) and Other financial components
Cemig D concession contract guarantees that, in the event of termination of the concession contract, for any reason, the remaining balances (assets and liabilities) of any shortfall in payment or reimbursement through the tariff must also be paid by the grantor. The balances on (i) the CVA (Compensation for Variation of Parcel A items) Account, (ii) the account for Neutrality of Sector Charges, and (iii) Other financial components in the tariff calculation, refer to the positive and negative differences between the estimate of the Company’s non-controllable costs and the costs actually incurred. The variations are subject to adjustment using the Selic rate and considered in the subsequent tariff adjustments. The balance of these sector financial assets and liabilities, which are presented at net value, in assets or liabilities, in accordance with the tariff adjustments that have been authorized, are as follows:

(1) | The wholly-owned subsidiary 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. On August 27, 2020, Aneel published the Dispatch 2,508/2020-SRM-SGT, which set new amounts for distributors’ over contracting for the years 2016 and 2017, based on a new valuation criterion established by Aneel Technical Note 97/2020-SRM-SGT – not contained in the regulatory rules which were currently in force. As a result, Cemig D filed an appeal with the Council of Aneel, for the amounts of distribution agents’ over contracting to be reset in accordance with the calculation criteria based on maximum effort contained in Aneel Normative Resolution 453/2011. The Company’s position on this case is reinforced by the fact that the Brazilian Energy Distributors’ Association (Abradee) filed a similar appeal, supported by the opinion of contracted legal advisors. The Company has no expectation of loss in relation to realization of these amounts. The Company recognizes this receivable asset, in the amount of R$222 on December 31, 2020, as ‘Other financial components’ to be ratified. At the reporting date for this financial statements, this matter was still pending analysis by Aneel.

Payments from the Flag Tariff Centralizing Account The ‘Flag Account’ (Conta Centralizadora de Recursos de Bandeiras Tarifárias – CCRBT or ‘Conta Bandeira’) manages the funds that are collected from captive customers of distribution concession and permission holders operating in the national grid, and are paid, on behalf of the CDE, directly to the Flag Account. The resulting funds are passed through by the Power Trading Chamber (CCEE) to distribution agents, based on the difference between the realized amounts of costs of thermal generation and the exposure to short term market prices, and the amount covered by the tariff in force. Pass-through of funds from the Flag Account in 2020 totaled R$63 (R$361 in 2019 and R$794 in 2018) and were recognized as a partial realization in advance of the following tariff adjustment. Cemig D tariff adjustment On June 25, 2020, the grantor (Aneel) approved the Annual Adjustment for Cemig D, which would be in effect from May 28, 2020 to May 27, 2021, with an average increase for customers of 4.27%. This result reflected Cemig D’s manageable costs (Portion B), of 0.84% and the direct pass-through, within the tariff, of 3.43%, the latter having zero economic effect, not affecting profitability, relating to the following itens: (i) increase of 5.30% in non-manageable (‘Parcel A’) costs – mainly purchase of energy supply, regulatory charges and transmission charges; (ii) increase of 6.71% in the financial components of the current process, led by the CVA currently being processed, which had an effect of 5.47%; and (iii) 8.58% was withdrawn from the financial components of the prior process. Although the adjustment is effective from May 28, 2020 to May 27, 2021, its application was suspended until June 30, 2020, maintaining the previous tariffs during the suspension period. Cemig D also recognized the right to receive a total of R$51, based on the energy market, for non-receipt of the additional tariff component in the period. Considering that the amount of R$63 was received from Covid Account funds on July 31, 2020, completing the total amount established for Cemig D to receive in Covid Account funds, under Normative Resolution 885/2020, the Company recognized a net obligation of R$12, updated by the Selic rate until September 30, 2020. For more information on the Covid-account, see Note 1(e) to this financial statements. Administrative appeals were filed with Aneel, contesting the ratification of the annual tariff increase of 4.27% to Cemig D, and requesting its annulment, with the restitution to Cemig D’s customers of the amounts of the escrow deposits released as a result of the Supreme Court judgment, as decribed in Note 12, in the form that creates overall precedent, which determined the exclusion of ICMS tax amounts from the basis for calculation of PIS/ Pasep and Cofins taxes payable. The current administrative appeals request a creation of a negative financial component in the calculation of Cemig D’s annual tariff adjustment. Aneel has given Cemig D the right of reply, and, based on internal assessments and those of its legal advisers, as well as the exceptional economic scenario caused by the Covid-19 pandemic, Cemig D, on August 5, 2020, has submitted to Aneel a proposal for a the restitution to its customers of a total amount of R$714 – corresponding to part of the escrow deposits released by the court due to Cemig’s success in the Claim. On August 18, 2020, Aneel decided to grant the appeal, in part, and through its Ratifying Resolution 2,757/2020 reduced the average effect of Cemig D’s 2020 tariff adjustment to zero, due to the inclusion of the negative financial component of R$714. Cemig’s decision represents an anticipation of the effects, and treatment in terms of regulations of the Supreme Court’s decision that determined the exclusion of ICMS tax amounts from the basis for calculation of PIS/ Pasep and Cofins taxes. These regulations will be applied equally to all energy distribution concessions through an Aneel normative ruling, which will be issued after conclusion of Public Consultation 005/2020 – during which there will be discussion on the merits, and in which Cemig will be able to take part in a wide-ranging discussion on the subject. The portion of the credits that Cemig D proposes to reimburse to its customers is recognized as a liability, as explained in Note 21. Of this amount, R$266, had been passed through to customers tariff by December 31, 2020.
