| (1) | On December 31, 2020 and 2019, the investee has negative net equity. Thus, after reducing the accounting value of its interest to zero, the Company recognized the provision for losses to the extent of its obligations, in the amount of R$30 (R$22 on December 31, 2019), resulting from contractual obligations assumed with the jointly-controlled entity and the other shareholders.
The Company’s investees that are not consolidated are jointly-controlled entities, with the exception of the interests in the affiliates Light, classified as asset held for sale, Madeira Energia ‘Santo Antônio’ power plant and Ativas Data Center. On December 31, 2019, the investee ‘Usina Hidrelétrica Itaocara’ had negative shareholders’ equity. Thus, after reducing the accounting value of its interest to zero, the Company recognized the loss to the extent that it assumed contractual obligations with the subsidiary and the other shareholders, which on December 31, 2020 is R$30 (R$22 on December 31, 2019). On December 31, 2020, management considered that there was some indication, due to the economic shock of the Covid-19 pandemic (Note 1e), of potential decline in value of assets, as referred to in IAS 36– Impairments of Assets. Considering, however, the pandemic’s effects on the economic context, and the fact that the long-term expectation of realization of the assets underwent no change, management of the Company assessed the recoverable amount of the assets for which there were indications that they may be impaired and concluded that the reported assets net carrying amount is recoverable, and thus that there was no need to recognize any impairment loss in the Company nor its subsidiaries as a result of the current economic scenario. Additionally, in relation to the above, the Company’s management has assessed the risk threatening all its investments ability to continue as a going concern, taking substantially into consideration: the economic-financial clauses of Cemig D and Gasmig; the guarantee of revenues of the transmission companies; the protection against force majeure reduction in regulated generation contracts; and all the legal measures that have been applied by the federal government and by Aneel – and has concluded that the Company and its subsidiaries’ ability to continue as going concern is secure.

Madeira Energia S.A. (‘MESA’) and FIP Melbourne MESA is the parent company of Santo Antônio Energia S.A (‘SAESA’), whose objects are operation and maintenance of the Santo Antônio Hydroelectric Plant and its transmission system, on the Madeira River. MESA’s shareholders include Furnas, Odebrecht Energia, SAAG and the Company. On December 31, 2020 MESA reported a loss of R$1,445 (R$951 on 2019) and negative net working capital of R$205 (R$427 on 2019). Hydroelectric plants project finances structurally present negative net working capital in the first years of operation, because they are built using high levels of financial leverage. On the other hand, they have firm long term contracts for energy supply as support and guarantee of payment of their debts. To balance the situation of negative working capital, in addition to its long-term sale contracts that ensure regularity in its operational cash flow, MESA benefits from its debt reprofiling, which adjusted its debt repayments flow to its cash generation capacity, so that the investee does not depend on additional investment from the shareholders. Arbitration proceedings In 2014, Cemig GT and SAAG Investimentos S.A. (SAAG), a vehicle through which Cemig GT holds an indirect equity interest in MESA, opened arbitration proceedings, in the Market Arbitration Chamber, challenging the following: (a) the approved increase in the capital of MESA of approximately R$678 partially to be allocated to payment of the claims by the Santo Antonio Construction Consortium (‘CCSA’), based on absence of quantification of the amounts supposedly owed, and absence of prior approval by the Board of Directors, as required by the bylaws and Shareholders’ Agreement of MESA; and also on the existence of credits owed to MESA by CCSA, for an amount greater than the claims; and (b) against the adjustment for impairment carried out by the Executive Board of MESA, in the amount of R$678, relating to certain credits owed to Mesa by CCSA, on the grounds that those credits are owed in their totality by express provision of contract. The arbitration judgment recognized the right of Cemig GT and SAAG in full, and ordered the annulment of the acts being impugned. As a consequence of this decision, MESA reversed the impairment, and posted a provision for receivables in the amount of R$678 in its financial statements as of December 31, 2017. On December 31, 2020, the investee confirmed its assets recoverability expectation and maintained the provision for receivables in the amount of R$678. To resolve the question of the liability of the CCSA consortium to reimburse the costs of re-establishment of the collateral and use of the contractual limiting factor, the affiliated company opened arbitration proceedings with the International Chamber of Commerce (ICC) against CCSA, which are in progress. This process is confidential under the Arbitration Regulations of the ICC. Cemig GT and SAAG Investimentos S.A. applied to the judiciary for provisional remedy prior to the arbitration proceeding, to suspend the effects of the capital increase approved by an Extraordinary General Meeting of Shareholders of Mesa held on August 28, 2018.

Renova Energia S.A. - court-supervised reorganization (‘Renova’) The investee Renova, currently in court-supervised reorganization, has been reporting recurring losses and presenting negative net working capital, net equity (uncovered liabilities) throughout the past years. On December 31, 2020, the jointly-controlled investee Renova, reported a consolidated profit of R$22 (loss of R$1,014 in 2019 and R$856 in 2018), accumulated losses of R$ 3,994 (R$ 4,017 in 2019 and R$3,058 in 2018), an equity deficit of R$1,108 (R$1,130 in 2019 and R$100 in 2018). Renova reported a positive net working capital in 2020 of R$273, in contrast to the negative net working capital reported in the past years of R$2,907 in 2019 and R$457 in 2018. This scenario reflects the court-supervised reorganization plan, which provide the agreements to balance the group liabilities, the renegociation of interest rates and the extension of debts maturity. In view of the investee’s equity deficit, the Company reduced the carrying value of its equity interests in Renova, at December 31, 2018, to zero and no further losses have been recognized, considering the non-existence of any legal or constructive obligations to the investee. Additionally, the Company recorded, since June 30, 2019, an impairment of the receivables with the jointly-controlled entity in the amount of R$688. Renova for court-supervised reorganization On October 16, 2019, was granted court-supervised reorganization petition applied by Renova, and by the other companies of the group (‘the Renova Group’). On October 25, 2019, Cemig GT made an Advance for Future Capital Increase to Renova, of R$5 and subsenquently was agreeded between the Company and Renova a Debtor in Possession (DIP) loan agreements in the total amount of R$37. The funds of these loans, made under specific rules of court-supervised reorganization proceedings, were necessary to support the expenses of maintaining the activities of Renova, and were authorized by the second State of São Paulo Bankruptcy and Court-supervised Reorganization Court. They are guaranteed by a fiduciary assignment of shares in a company owning assets of a wind power project owned by Renova, and they also have priority of receipt in the court-supervised reorganization process. On May 2, 2020, the State of São Paulo Bankruptcy and Court-supervised Reorganization Court issued a decision ordering that the DIP loan, in the total amount of R$37, with asset guarantee, already constituted and registered, would be subscribed as a capital increase in Renova. Company has filed a Motion for Clarification and in a virtual and permanent session of the 2nd Chamber of Business Law of the São Paulo Court of Justice, decided to uphold the appeal. Thus, the clauses of the court-supervised plan that deal with the loan contracts signed by the Company are maintained, for a while. On September 21, 2020, Renova approved the proposal made by the Company for suspension of the obligations in the PPA signed between them, as amended from time to time, for incentive-bearing wind power which were linked to phase A of the Alto Sertão III Wind Complex. The suspension will remain in effect until the beginning of the commercial operation of the facilities aimed at the Free Market, planned for December 2022, and is duly aligned with the strategic planning set out for compliance with the Renova reorganization plan. On October 8, 2020, the Board of Renova approved acceptance of the binding proposal presented by Prisma Capital Ltda. for acquisition of the rights and assets related to Phase B of the Alto Sertão III Wind Complex, under first proposer (‘Stalking Horse’) conditions, with right of preference in the acquisition, subject to the usual conditions precedent, including approval by a General Meeting of Creditors, which occurred on December 18,2020. The proceeds obtained will be specifically directed to compliance with its obligations under the Court-Supervised Reorganization Plan and restart of the works on Phase A of the Alto Sertão III Wind Complex. On December 18, 2020, the General Meeting of Creditors approved the court-supervised reorganization plans submitted to the court by Renova. The economic and financial reasonableness of the two plans was presented at the creditors’ meeting, as follows:
(i) | raising of a bridge loan for completion of the Alto Sertão III wind complex – this was signed on December 17, 2020, in the amount of R$350, in the Debtor in Possession (DIP) financing form, by the subsidiary Chipley SP Participações S.A., with co-obligations by Renova Energia S.A. And Renova Participações S.A., to be allocated specifically to resumption of the works on Phase A of the Alto Sertão III Wind Complex;
(ii) | sale of assets, principally the shareholding in Brasil PCH, and some wind power ongoing projects;
(iii) | renegotiation of the period for settlement of liabilities, with alteration only of maturities, and not amounts; and
(iv) | conclusion of the works on the Alto Sertão III Wind Complex.
In this sense, the plans describe the means of recovery in detail, give details of the DIP bridge loan, identify the Isolated Production Units (UPIs) and specify the procedure for resources disposal and allocation. The mainly effects of the approval of the court-supervised reorganization plan on Renova’s financial statements at December 2020 are as follow:
(i) | the investments in Brazil PCH, Enerbras, AS III Phase B and Mina de Ouro are presented as held for sale, in current assets;
(ii) | liabilities were updated from the date of application for court-supervised reorganization until December 31, 2020 at 100% of the CDI rate;
(iii) | the liabilities to controlling shareholders were updated from the date of approval of the application for court-supervised reorganization, at 100% of the CDI rate; and
(iv) | the interest provisioned for the period between approval of the application and approval of the plan was reversed.
On February 11, 2021, PSS Principal Fundo de Investimento em Participações Multiestratégia, managed by Prisma Capital Ltda., won the competitive tender for sale of the Phase B UPI specified in the Renova Group’s court-supervised reorganization Plan, with the proposal of R$58, 16.77% higher than the minimum value specified in the Plan. Renova and the PSS Principal Fund will sign the final instruments for acquisition, in the terms of the Tender of the Phase B UPI, in order to begin compliance with the precedent conditions that are usual in such transactions. Further, on March 1, 2021 the Board of Directors of Renova approved an increase in the share capital of this investee of until R$1,421, with the condition that partial subscription of R$ 332 or more, corresponding to the amount of the credits to be capitalized under the Plans, will be accepted. The capital increase and its final amount are subject to approval by the Board of Directors, after expiry of the periods for exercise of rights of first refusal and subscription of leftover shares by holders of subscription rights. The Company is not part of the group of creditors that requested conversion of their credits into equity, and also will not subscribe any part of the capital increase. As a result, the equity interest held by the Company in Renova will be reduced from 29.81% to 15.15% of the total capital, considering that no other shareholder subscribes the capital increase. There will be no effect on the present jointly control of Renova. On March 2, 2021 the contract for sale of shares of the Phase B UPI was signed, on the terms specified in the Tender of that UPI and in the Renova Group’s court-supervised reorganization Plan, subject to implementation of the suspensive conditions that are usual in the market. On March 5, 2021, in the context of the court-supervised reorganization, Renova received R$362 from the Debtor in Possession financing contracted by its subsidiary Chipley SP Participações S.A. – in court-supervised reorganization with co-obligations by Renova and Renova Participações S.A. – in court-supervised reorganization, through a Bank Credit Note structured by Quadra Gestão de Recursos S.A. (‘Quadra Capital’) and issued in favor of QI Sociedade de Crédito Ltda., as specified and authorized in the court-supervised reorganization proceedings of the Renova Group, currently under the 2nd Court for Bankruptcies and Court-Supervised Reorganization of the Legal District of São Paulo State. The funds obtained will enable resumption of the works for conclusion of construction and start of commercial operation of Phase A of Alto Sertão III. Considering the non-existence of any legal or constructive obligations to the investee, the Company has concluded that the granted of court-supervised reorganization filed by Renova and approved by the court does not have any additional impact in its financial statements. Amazônia Energia S.A. and Aliança Norte Energia S.A. Amazônia Energia and Aliança Norte are shareholders of Norte Energia S.A. (‘NESA’), which holds the concession to operate the Belo Monte Hydroelectric Plant. Through the jointly-controlled entities referred to above, Cemig GT owns an indirect equity interest in NESA of 11.69%. On December 31, 2020 NESA presents negative net working capital of R$160 (R$3.309 on December 31, 2019), and will spend further amounts on projects specified in its concession contract, even after conclusion of the construction and full operation of the Belo Monte Hydroelectric Plant. According to the estimates and projections, the negative net working capital, and the future demands for investments in the hydroelectric plant, will be supported by revenues from future operations and/or raising of bank loans. NESA joined the BNDES Program to Support Maintenance of Productive Capacity, Employment and Income, in the context of the Covid-19 pandemic crisis, obtaining suspension of the FINEM Direct Installment payment from June to November 2020, and the FINEM Indirect Installment payment from July to December 2020, and in consequence, it cannot distribute dividends greater than 25% in 2020. The investee’s adherence to this program contributed significantly to reduction of its negative net working capital on December 31, 2020. On September, 2015, NESA was awarded a preliminary injunction ordering the regulator to ‘abstain, until hearing of the application for an injunction made in the original case, from applying to Appellant any penalties or sanctions in relation to the Belo Monte Hydroelectric Plant not starting operations on the date established in the original timetable for the project, including those specified in an the regulator (Aneel) Normative Resolution 595/2013 and in the Concession Contract for the Belo Monte Hydroelectric Plant’. The legal advisors of NESA have classified the probability of loss as ‘possible’ and estimated the potential loss on December 31, 2020 to approximately R$2,407 (R$1,962 on December 31, 2019).
d) | Business combination - Centroeste

(‘Cemig Sim’) acquired 49% of interest in seven special-purpose companies operating in photovoltaic solar generation for the distributed generation market (‘geração distribuída’), with total installed capacity of 29.45MWp, for R$55. On August 19, 2020 and on September 30, 2020, this wholly-owned subsidiary also acquired 49% of interest in two others SPCs operating in the same market segment for R$8 and R$10, respectively, with total installed capacity of 11.62 MWp. Cemig Sim acquired the shares as result of exercising a call option, which granted Cemig Sim the right to buy 49% of the shares of the special-purpose companies that were owned by Mori Energia Holding S.A, as established in the Memorandum of Understanding (MOU) signed in June 2019. The conditions established in the shareholders agreements signed by Cemig Sim and Mori Energia in order to determine the entities management composition and their corporate governance lead to the their qualification as jointly controlled entities.

The excess of the Cemig Sim’s share of the net fair value of the investee’s identifiable assets and liabilities over the cost of the investment (bargain purchase) was included as income in the determination of the Cemig Sim’s share of the entities’ profit or loss in the period in which the investment was acquired. The deferred tax liability was recognized, according to IAS 12. f) Risks related to compliance with law and regulations Jointly controlled entities and affiliates: Norte Energia S.A. (‘NESA’) - through Amazônia Energia and Aliança Norte Investigations and other legal measures are in progress since 2015, conducted by the Federal Public Attorneys’ Office, which involve other shareholders of NESA and certain executives of those other shareholders. In this context, the Federal Public Attorneys have started investigations on irregularities involving contractors and suppliers of NESA and of its other shareholders, which are still in progress. At present, it is not possible to determine the outcome of these investigations, and their possible consequences. These might at some time in the future affect the investee. In addition, based on the results of the independent internal investigation conducted by NESA and its other shareholders, an infrastructure write-down of R$183 was already recorded at NESA, and reflected in the Company’s consolidated financial statements through the equity pick effect in 2015. On March 9, 2018 ‘Operação Buona Fortuna’ started, as a 49th phase of ‘Operation Lava Jato’ (‘Operation Carwash’). According to what has been disclosed by the media this operation investigates payment of bribes by the construction consortium of the Belo Monte power plant, comprising the companies Camargo Corrêa, Andrade Gutierrez, Odebrecht, OAS and J. Malucelli. Management of NESA believes that so far there are no new facts that have been disclosed by the 49th phase of ‘Operation Carwash’ that require additional procedures and internal investigation in addition to those already carried out. The Company’s management, based on its knowledge of the matters described above and on the independent procedure carried out, believes that the conclusions presented in the report of the independent investigation are adequate and appropriate. As a result, no adjustment has been made on its financial statements. The effects of any future changes in the existing scenario will be reflected appropriately in the Company’s financial statements. Madeira Energia S.A. (‘MESA’) There are ongoing Investigation and other legal measures conducted by the Federal Public Attorneys’ Office, which involve other indirect shareholders of MESA and certain executives of those other indirect shareholders. In this context, the Federal Public Attorneys have started investigations searching for irregularities involving contractors and suppliers of MESA and of its other shareholders. In response to allegations of possible illegal activities, the investee and its other shareholders started an independent internal investigation. The independent internal investigation, concluded in February 2019, in the absence of any future developments such as any leniency agreements by third parties that may come to be signed or collaboration undertakings that may be signed by third parties with the Brazilian authorities, found no objective evidence enabling it to be affirmed that there were any supposed undue payments by MESA (SAESA) that should be considered for possible accounting write-off, pass-through or increase of costs to compensate undue advantages and/or linking of MESA with the acts of its suppliers, in the terms of the witness accusations and/or cooperation statements that have been made public. The Company’s management, based on its knowledge of the matters described above and on the independent procedures carried out, believes that the conclusions presented in the report of the independent investigation are adequate and appropriate. As a result, no adjustment has been made on its financial statements. The effects of any future changes in the existing scenario will be reflected appropriately in the Company’s financial statements. Renova Energia S.A. (‘Renova’) Since 2017 Renova has been part of a formal investigation by the Civil Police of Minas Gerais State and other public authorities related to certain capital injections made by some of its controlling shareholders, including the Company and capital injections made by Renova in certain projects under development in previous years. On April 11, 2019, the Brazilian Federal Police commenced the ‘Operation E o Vento Levou’ as part of the Lava Jato Investigation, and executed a search and seizure warrant issued by a Federal Court of São Paulo at Renova’s head office in São Paulo, based on allegations and indications of misappropriation of funds harmful to the interests of Cemig. Based on the allegations being investigated, these events are alleged to have taken place before 2015. On July 25, 2019 the second phase of such investigation initiated. The ‘Operation E o Vento Levou’ and the police investigation by the Minas Gerais State Civil Police have not yet concluded. Thus, there is a possibility that material information may be revealed in the future. If a criminal action is filed against agents who damaged Renova, Renova intends to act as auxiliary to the prosecution in any criminal proceedings, and subsequently sue for civil recovery of the damages suffered. Due to these third party investigations, the governance bodies of Renova requested opening of an internal investigation, conducted by an independent company with the support of an external law firm, the scope of which comprises assessment of the existence of irregularities, including noncompliance with: the Brazilian legislation related to acts of corruption and money laundering; Renova’s Code of Ethics; and its integrity policies. Additionally, a Monitoring Committee was established in Renova which, jointly with the Audit Committee, accompanied this investigation. The internal investigation was concluded on February 20, 2020, and no concrete evidences of acts of corruption or diversion of funds to political campaigns was identified. However, the independent investigators identified irregularities in the conducting of business and agreement of contracts by Renova, including: (i) payments without evidence of the performance of services, in the total amount of approximately R$40; (ii) payments not in accordance with the company’s internal policies and best governance practices, in the total amount of approximately R$137; and (iii) deficiencies in the internal controls of the investee. As a result of the analysis of the above mentioned values, Renova concluded that R$35 relates to effective assets and therefore no impairment is necessary. The remaining amount of R$142 was already impaired in previous years, producing no impact on the consolidated financial statements for the year ended December 31, 2019 and December 31, 2020. In response to the irregularities found, and based on the recommendations of the Monitoring Committee and legal advisers, the Board of Directors of Renova decided to take all the steps necessary to preserve the rights of the investee, continue with the measures to obtain recovery of the losses caused, and strengthen the company’s internal controls. Since the investment at Renova is fully impaired at December 31, 2020, and since no contractual or constructive obligations in relation to the investee have been assumed by the Company, it is not expected that effects resulting from the court-supervised reorganization process, or the investigations, or the operational activities of this investee can significantly impact the Company’s financial statements, even if such effects may not yet recorded by Renova. Other investigations In addition to the cases above, there are investigations being conducted by the Public Attorneys’ Office of the State of Minas Gerais (‘MPMG’) and by the Civil Police of the State of Minas Gerais (‘PCMG’), which aim to investigate possible irregularities in the investments made by the Company in Guanhães Energia and also in MESA. Additionally, on April 11, 2019 agents of the Brazilian Federal Police were in the Company’s head office in Belo Horizonte to execute a search and seizure warrant issued by a São Paulo Federal Court in connection with the ‘Operation E o Vento Levou’, as described above. These proceedings are being performed through reviewing documents demanded by the respective authorities, and by hearing of witnesses. Internal procedures for risks related to compliance with law and regulations Taking into account the investigations that are being conducted by public authorities relating to the Company and to certain investees, the governance bodies of the Company have authorized contracting specialized advisers to analyze the internal procedures related to these investments, as well as internal proceedings related to the acquisition of Light’s interest in Enlighted (see Note 25 of the Financial Statements). This independent investigation was subject to oversight of an independent Special Investigation Committee whose creation was approved by our Board of Directors. The Company’s internal investigation was completed and the corresponding report was issued on May 8, 2020, and identified no objective evidence substantiating illegal acts made by Company in the Company’s investments that were the subjects of the investigation. Therefore, there was no impact in the Company consolidated financial statements, neither for the year ended in December 31, 2020 nor for prior periods. Due to the completion of the internal investigations for which the Special Investigating Committee was constituted, the governance bodies of the Company decided to extinguish that Committee. If future needs arise from developments in this matter, the Committee can be reinstated. In 2020, the Company began internal procedures for investigation of allegations that are the subject of inquiries by the Minas Gerais State Public Attorneys’ Office regarding certain alleged irregularities in public bidding purchasing processes. The investigation is being conducted by a new Special Investigation Committee (Comitê Especial de Investigação – CEI), with support from specialized independent advisers. In the second semester of 2019, Company signed tolling agreements with the Securities and Exchange Commission (SEC) and US Department of Justice (DOJ), which was extended in February 2021 for an additional period of six months. Cemig continues to cooperate with the SEC and the DOJ. The Company will evaluate any changes in the future and potential impacts that could affect the financial statements, if appropriate. The Company will continue to cooperate with the relevant domestic and foreign authorities in these investigations.
