11 CEMIG CONDENSED EXPLANATORY NOTES TO THE INTERIM FINANCIAL STATEMENTS PERIOD ENDED SEPTEMBER 30, 2012 (Figures in R$ ’000, except where otherwise indicated) 1. OPERATIONAL CONTEXT Companhia Energética de Minas Gerais (“Cemig” or “the Company”) is a listed corporation registered in the Brazilian Registry of Corporate Taxpayers (CNPJ) under number 17.155.730/0001-64, with shares traded at Corporate Governance Level 1 on the BM&F Bovespa (“Bovespa”), on the New York Stock Exchange (“NYSE”), and on the stock exchange of Madrid (“Latibex”). It is domiciled in Brazil, with head office at Avenida Barbacena 1200, Belo Horizonte, in the State of Minas Gerais, and operates exclusively as a Parent Company, with stockholdings in companies controlled individually or jointly, the main objects of which are construction and commercial operation of systems for generation, transformation, transmission, distribution and sale of electricity, and activities in the various fields of energy. On September 30, 2012 Cemig’s current liabilities exceeded its current assets by R$ 1,051,806. Management monitors the Company’s cash flow and takes measures to adjust its situation to the levels considered appropriate to meet its needs, paying debts becoming due or extending their maturity dates through issues of long-term debentures. 2. BASIS OF PREPARATION 2.1. Statement of compliance The Individual Interim Financial Statements are prepared in accordance with Technical Pronouncement 21 (R1) – Interim Statements (Pronunciamento Técnico 21 – Demonstração Intermediária, or CPC 21). The Consolidated Interim Financial Statements are prepared in accordance with CPC 21 (R1), and also in accordance with IAS 34 – Interim Financial Reporting, issued by the International Accounting Standards Board (IASB). Both are presented in a form compliant with the rules issued by the Brazilian Securities Commission (Comissão de Valores Mobiliários, or CVM), applicable to preparation of Quarterly Information (Informações Trimestrais, or ITR). These Interim Financial Statements have been prepared according to principles, practices and criteria consistent with those adopted in the preparation of the annual Financial Statements for December 31, 2011. Thus, these Interim Financial Statements should be read in conjunction with the said Financial Statements, approved by the Executive Board on March 6, 2012 and filed with the CVM on March 28, 2012. The individual Interim Financial Statements of the Parent Company were prepared in accordance with BR GAAP. In the case of the consolidated statements, these practices

12 CEMIG differ from the IFRS applicable to separate Interim Financial Statements in that the valuation of the investment in subsidiaries, affiliated companies and joint ventures, in BR GAAP, is by the equity method, while for the purposes of IFRS this valuation is at cost or fair value. However, there is no difference between the totals presented for Stockholders’ equity and Consolidated Net profit in the consolidated financial statements, and the totals presented for the Stockholders’ equity and Net profit of the Parent Company in the individual financial statements of the Parent Company. Thus, the consolidated Interim Financial Statements of the Company and the individual Interim Financial Statements of the Parent Company are being presented side-by-side in a single group of Financial Statements. 2.2.

With the transfer, Taesa will own 74.49% of EBTE, based on the holding of 49% transferred by Cemig GT, plus an indirect holding through EATE of 51% (Taesa owns 49.98% of the shares in EATE) (jointly referred to as “the TBE Group”). Under the same agreement, Cemig undertakes to transfer to Taesa the totality of the shares held by Cemig in the electricity transmission companies of the TBE Group: ETEP (49.98%); ENTE (49.99%); ERTE (49.99%); EATE (49.98%) and ECTE (19.09%). Conclusion of this stockholding restructuring transaction, and final transfer of the assets referred to above, is still subject to the implementation of certain conditions precedent before it can take effect, of which the most important are (i) consent of the

25 CEMIG Company’s creditors, and (ii) approval of the transaction by the regulator, Aneel. The acquisition will also (iii) need to be approved by the monopolies authority, Cade. Under the Transmission Assets Investment Contract, Taesa is not allowed to dispose of, assign or transfer its holdings in the companies of the TBE Group before expiry of 120 months from the date of actual transfer of the said stockholdings, unless previously authorized by Cemig – but during that period Taesa may make total or partial disposal, assignment or transfer of any stockholding that it holds in the companies of the TBE Group provided that it transfers to Cemig the positive difference obtained on such disposal, assignment or transfer, the comparison being between the value of the consideration for the disposal, assignment or transfer and the amount for which the holdings in the TBE Group were transferred to Taesa, duly updated by the variation of the Selic rate published by the Brazilian Central Bank up to the date of the actual disposal, assignment or transfer. Contract to assume obligations – change in stockholders’ agreement On June 29, 2012 the indirect jointly-held subsidiary Taesa, together with Alupar Investimento S.A. (holder, with Cemig and Cemig GT, of control of the companies of the TBE Group) signed a private contract to assume obligations, agreeing the following: On January 2, 2013 (or on the date of transfer of the holdings in the companies of the TBE Group to Taesa, whichever is later), amended versions of the Stockholders’ Agreements of the companies in the TBE Group come into effect, and the changes to the respective by-laws must have been voted by Alupar Investimento S.A. and Taesa. Based on the above, it is Taesa’s understanding that it will cease to hold shared control of the companies of the TBE Group when the amended stockholders’ agreements referred to come into force, and that it will from then on have significant influence in those companies. Acquisition of the TBE companies – approvals to date On July 25, 2012 the request for consent to the transfer of a percentage interest in the concessions (subject of the stockholding restructuring) was filed with Aneel. On October 4, 2012 the Company updated the documents submitted to Aneel, to continue with the process. The matter is currently being considered by Aneel’s Economic and Financial Inspection Department (Superintendência de Fiscalização Econômica e Financeira, or SFF/Aneel), which is expected to state its position on the transaction by December of this year.

26 CEMIG Acquisition by Taesa of the remaining 50% of Unisa On July 3, 2012 Taesa concluded acquisition of the remaining 50% of the shares in Unisa held by Abengoa Concessões Brasil Holding S.A. This transaction was approved by Cade on July 4, 2012. Unisa was previously jointlycontrolled by Taesa and Abengoa and, on July 3, 2012 became a wholly-owned subsidiary of Taesa. The total value of the consideration paid for the acquisition of the holding was R$ 876,865, comprising R$ 903,910 paid in cash, which includes the accumulated variation of the Selic rate up to the rate of conclusion of the transaction, net of the constitution of the dividends receivable in the amount of R$ 27,045 on the date of conclusion of the transaction, as per the terms of the contract signed by the parties. New issue of shares by Taesa On July 19, 2012 the indirectly jointly-controlled subsidiary Taesa issued 24 million Units in a public share offering, at R$ 65 per Unit. The Units in this transaction comprise one common share and two preferred shares, all nominal, of the book-entry type and without par value. On August 20, 2012, the supplementary lot of the public share offering, of three million Units, was exercised in its entirety, resulting in a total of 27 million Units under the public share offering. The share capital of Taesa was increased, within the limit of its authorized capital ceiling of R$ 1.755 billion, by issuance of 81 million new shares: 27 million common and 54 million preferred. Following the increase the share capital of Taesa is R$ 3,067,535 which, after deduction of the issue costs of R$ 38,883, totaled R$ 3,028,652, comprising 344,498,907 nominal, book-entry shares without par value: 230,517,711 common and 113,981,196 preferred. Pursuant to Article 172, I, of the Brazilian Corporate Law and Article 9 of the Company’s by-laws, there was no first refusal right for existing stockholders of the Company in the subscription. With this issuance of shares Cemig GT reduces its percentage equity interest in Taesa, from 56.69% to 43.36% of the total capital, comprising 97,690,743 common shares and 51,683,548 preferred shares, as follows: STOCKHOLDERS COMMON SHARES PREFERRED SHARES TOTAL Number of shares % Number of shares % Number of shares % Taesa: Total shares issued 230,517,711 100.00% 113,981,196 100.,00% 344,498,907 100.00% Cemig GT 97,690,743 42.38% 51,683,548 45.34% 149,374,291 43.36% This table shows the Company’s stockholding on December 31, 2011: STOCKHOLDERS COMMON SHARES PREFERRED SHARES TOTAL Number of shares % Number of shares % Number of shares % Taesa: Total shares issued 203,517,711 100.00% 59,981,196 100.00% 263,498,907 100.00% Cemig GT 97,690,743 48.00% 51,683,548 86.17% 149,374,291 56.69%

27 CEMIG Effects of the Taesa public share offering on the profit of Cemig As mentioned, Taesa made an issue of shares at the price of R$ 65, which was higher than the book value of the shares in Taesa prior to the issue, even including in the calculation the added value of the concession resulting from the process of acquisition by Cemig GT of an equity interest in Taesa. This difference between the book value and the issue value gave rise to a gain in the amount of R$ 253,538, reported in the profit and loss account of Cemig for the third quarter of 2012. Madeira Energia S.A. The jointly-controlled subsidiary Madeira Energia S.A. – MESA (“Mesa”) is an unlisted corporation, constituted on August 27, 2007, the objects of which are construction and commercial operation of the Santo Antônio Hydroelectric Plant located on the Madeira River, and its Associated Transmission System, under the terms of Concession Contract for Use of a Public Asset Nº 001/2008-MME. Mesa is at a pre-operational phase, and thus is in need of financial support from its joint controlling stockholders. The injection of R$ 217,073 arises from paying-up of subscriptions of shares in 2012, duly approved in Minutes, in accordance with the investment plan approved in the Notice of Board Spending Decision CRCA 089/07 by Cemig’s Board of Directors. Mesa has suffered recurring losses in its operations, and on September 30, 2012 its current liabilities exceeded current assets by R$ 1,943,146. The proportional effect on Cemig is R$ 194,315. Its management has plans to correct the situation of negative net working capital. As of this writing, Mesa depends on the financial support of its stockholders and/or on obtaining loans from third parties to continue operating. Mesa and its subsidiary are incurring costs of constitution relating to the construction of the Santo Antônio Hydroelectric Plant. The value of the fixed asset built with this expenditure totaled R$ 13,800,064 on September 30, 2012 which, according to the financial forecasts prepared by its management, will be absorbed by future revenues generated when the unit starts operating. On September 30, 2012 the value of the fixed assets proportional to Cemig’s equity ownership in this jointly-controlled subsidiary was R$ 1,380,006.

28 CEMIG Acquisition of an interest in Guanhães Energia S.A. (jointly-controlled subsidiary) On August 28, 2012 the subsidiary Light Energia S.A. finalized the transaction to acquire a holding in Guanhães Energia, in which it acquired 51% of the common shares, from Investminas Participações S.A. Guanhães was created to build four Small Hydroelectric Plants (PCHs) – Dores de Guanhães, Senhora do Porto, Jacaré and Fortuna II, all in the State of Minas Gerais, with aggregate installed generation capacity of 44.80 MW. The first of these PCHs is scheduled to start operating in October 2013, and the last in February 2014. Guanhães Energia S.A. is jointly controlled by Light Energia S.A. (51%) and by Cemig GT (49%). The value of the net assets acquired was R$ 26,586. The difference between the amount paid, R$ 26,586, and the book value of R$ 10,357 is stated as the added value of the concession, an identifiable intangible asset with defined useful life, which is reported in Intangible in the Statement of financial position (balance sheet). This asset will be amortized over the periods of the concessions, starting from the date of start of operation of each one of them. Dilution of equity interest in Renova Energia S.A., subsidiary of Light On July 13, 2012 Renova Energia S.A. and BNDES Participações S.A. (“BNDESPar”), a wholly-owned subsidiary of the Brazilian Development Bank (BNDES), entered into an agreement for BNDESPar to become a shareholder in Renova Energia. On September 26, 2012 the transaction was finalized with subscription payment by BNDESPar of 23,059,239 common shares and 4,875,036 preferred shares, arising from assignment, free of charge, to BNDESPar of the right of first refusal by RR Participações S.A., Light Energia S.A. and InfraBrasil Fundo de Investimento em Participações, as part of the capital increase transaction, at the issue price of R$ 9.3334 per share, for a total amount of R$ 314,702. After the transaction, the percentage interest owned by Cemig’s subsidiary Light Energia S.A. in Renova Energia S.A. was reduced from 25.9% to 22.0%. The transaction generated a gain for the subsidiary Light Energia of R$ 43,052, recorded in the line Equity gain (loss) in subsidiaries.

The useful life estimates established by Aneel are used in the processes of reviewing tariff rates and calculating the indemnification amounts due to concession holders at the end of the concession period, and are recognized as a reasonable estimate of the useful life of the assets of the concession. Thus, these rates were used as the basis for depreciation of the Company’s property, plant, and equipment assets. Useful life review On February 7, 2012 Aneel, by Normative Resolution 474, set new annual rates of depreciation for assets in service under electricity concessions based on a review of their useful lives. The new rates were applied as effective January 1, 2012. The Company has processed the changes in the rates, and recalculated the amount of the indemnity of the assets that are subject to reversion on expiry of the period of the Concession – 2016 for Cemig D, 2026 for Light – and of the amount attributable to Intangible Assets. This recalculation resulted in the reclassification of R$ 437,720 from Intangible assets to Financial assets, without change in the other accounting

Proceedings in which the Company is a debtor The Company, its subsidiaries and its jointly-controlled subsidiaries have made provisions for risks in tax, employment-law, regulatory and environmental legal proceedings in which the chances of loss are assessed as “probable” (i.e. it is expected that there will be an outflow of funds to settle the obligation), as follows: Consolidated Balance on Dec. 30, 2011 Additions (–) Reversals Write-off Effect of change of % stake in subsidiary Balance on Sep. 30, 2012 Labor claims 135,121 (6,844) (13,584) (119) 114,574 Civil lawsuits Consumer relations 88,195 (18,495) (1,336) - 68,364 Other civil cases 61,710 35,019 (14,853) (27) 81,849 149,905 16,524 (16,189) (27) 150,213 Tax 117,637 5,457 (1,561) 1,533 123,066 Environmental 56,635 24,825 (10,590) - 70,870 Regulatory 78,137 (7,248) (3,988) - 66,901 Other 12,004 7,436 (1,664) - 17,776 Total 549,439 40,150 (47,576) 1,387 543,400 Parent Company Balance on Dec. 30, 2011 Additions (–) Reversals Write-off Balance on Sep. 30, 2012 Labor claims 58,902 (10,088) (1,639) 47,175 Civil lawsuits Consumer relations 35,413 (15,348) (120) 19,945 Other civil cases 16,178 3,476 (383) 19,271 51,591 (11,872) (503) 39,216 Tax 33,342 (3,336) - 30,006 Environmental 207 20,796 - 21,003 Regulatory 38,210 (6,375) (88) 31,747 Other 3,700 2,099 (227) 5,572 Total 185,952 (8,776) (2,457) 174,719 Cemig’s management believes that any disbursements in excess of the amounts provisioned, when the related proceedings are completed, will not significantly affect the result of operations or the financial position of the Parent Company nor the consolidated result.

In addition to these actions, there are others relating to outsourcing of labor, complementary additions to or calculation of retirement pension payments by Forluz, and salary adjustments. The total amount of this contingency is approximately R$ 449,408 (R$ 523,697 on December 31, 2011), of which R$ 114,574 has been provisioned (R$ 135,121 on December 31, 2011). Consumer relations Cemig and its subsidiaries are parties in various actions for indemnity for pain and suffering arising, principally, from incidents involving the electricity distribution network, irregularities in measurement of consumption, and allegedly undue charging during the normal course of business, in the total amount of R$ 85,088 (R$ 189,088 on December 31, 2011), of which R$ 68,364 has been provisioned (R$ 88,195 on December 31, 2011). Among these actions there are proceedings relating to the accident on February 27, 2011 in the town of Bandeira do Sul. The more important aspect of these actions is not exclusively their financial impact, but the exposure of the Company’s image. Regulatory matters – tariff increases (under the “Cruzado Plan”) Several industrial consumers filed actions against Cemig and its subsidiaries seeking reimbursement for the amounts paid as a result of the tariff increase during the federal government’s economic stabilization plan known as the “Cruzado Plan”, in 1986, alleging that the said increase violated the control of prices instituted by that plan. The amount of the contingency is approximately R$ 36,782 (R$ 47,124 on December 31, 2011), of which R$ 31,974 has been provisioned (R$ 37,824 on December 31, 2011).

41 CEMIG Tax and similar charges – the Finsocial tax The federal government filed a rescission action against Cemig, to rescind the Appeal Court judgment given in the action for rescission previously filed by Cemig, on the subject of the Finsocial tax, with the argument that Cemig filed its action after the expiry period of two years. The contingency is estimated at R$ 94,871 (R$ 90,063 on December 31, 2011), of which R$ 22,341 has been provisioned (R$ 22,137 on December 31, 2011). Environmental actions The Company and its subsidiaries and jointly-controlled subsidiaries are involved in environmental matters, relating to protected areas, environmental licenses, recovery of environmental damages and other subjects, the potential cost of which could be approximately R$ 148,141 (R$ 79,468 on December 31, 2011), of which the Company has provisioned R$ 70,870 (R$ 56,635 on December 31, 2011). Santo Antônio Energia has made provisions for social and/or environmental situations, for estimates of expenses that will be incurred to mitigate the impacts caused by the construction of the Santo Antônio Hydroelectric Plant, in compliance with programs specified in Installation License 540 of 2008, in the amount of R$ 446,188 (R$ 452,643 on December 31, 2011). Cemig’s proportionate interest in this amount represents R$ 44,685 (R$ 45,264 on December 31, 2011).The environmental expenses provisioned were recorded as a cost of PP&E under construction – Reservoirs, dams and watercourses. Additionally, the Company is Defendant in several other class actions, mostly related to environmental damage, calling for indemnity, recovery of areas alleged to be degraded and compensation measures that will be, in most cases, defined in the course of the action. These actions may also benefit third parties not directly involved in the proceedings, who may be entitled to further reparations or indemnity. ICMS (local state value added tax) Since 1999, Light has been inspected on various occasions by the tax authority of Rio de Janeiro State in relation to the ICMS value added tax, charged by states. Infringement notices received so far and not paid are the subject of contestation in the administrative and legal spheres. The management, based on the opinion of its counsel and on analyzing the amounts involved in the infringement notices, believes that only part of these amounts represents a risk of loss that can be assessed as “probable”, and this is provisioned in the amount of R$ 111,794 (R$ 104,938 on December 31, 2011), Cemig’s participation representing a proportion of R$ 36,320 (R$ 34,092 on December 31, 2011). Gasmig made a provision for charges of ICMS tax on acquisition of property, plant and equipment used in its network, and for its application to the amount taxable by the PIS and Cofins taxes, totaling R$ 35,331 (R$ 28,838 on December 31, 2011). The portion of this relating to Cemig’s interest in Gasmig is R$ 21,047 (R$ 15,916 on December 31, 2011).

42 CEMIG Additionally, the Company is defendant in various actions relating to ICMS tax in relation to which, if it eventually has to pay the tax applicable to these transactions, it will be able to require reimbursement from consumers to recover the amount of the tax plus any penalty payment. The principal cases are: (i) A case relating to non-payment of ICMS tax on the installments that comprise the TUSD, and on demand contracted and not used, which were billed over the period from January 2005 through December 2010, since the amount of the tax applicable was excluded from electricity bills, in compliance with an interim injunction granted. (ii) A class action against Cemig D filed by the Minas Gerais Consumer Defense Institute (Instituto Mineiro de Defesa do Consumidor, or Imidec), questioning the charging of ICMS tax on the total amount and not only on the service provided. (iii) Cemig was served an infringement notice, as co-responsible party, in relation to transactions by industrial consumers to sell excess electricity during the period of rationing of electricity, on which payment of ICMS tax was demanded by the Tax Department of Minas Gerais State. No provision has been constituted. The estimated amount of the contingency is R$ 444,344 (R$ 434,004 on December 31, 2011). 1) Cases in which the chances of loss are assessed as “possible” – where the Company believes it has arguments of merit for legal defense: Contingent liabilities Tax and similar charges The Company and its subsidiaries and jointly-controlled subsidiaries are parties in numerous administrative and court proceedings in relation to taxes. Below are details of the principal cases: indemnity for employees’ future benefit – the “Anuênio” In 2006 the Company paid an indemnity to the employees, totaling R$ 177,685, in exchange for the rights to future payments for time of service which would otherwise be incorporated, in the future, into salaries. The Company did not make the payments of income tax and social security contribution on this amount because it considered that these obligations are not applicable to amounts paid as indemnity. However, to avoid the risk of a future fine arising from a differing interpretation by the federal tax authority (Secretaria da Receita Federal) and the National Social Security Institution (Instituto Nacional de Seguridade Social, or INSS), the Company decided to apply for an order of mandamus, and the result was that the Company was allowed to make an escrow payment into court of R$ 119,700. These are posted in Escrow deposits in litigation. The updated amount of the contingency is R$ 201,767 (R$ 191,770 on December 31, 2011).

43 CEMIG Profit sharing The National Social Security Institute (INSS) opened administrative proceedings against the Company, in 2006, for non-payment of social security contributions on the amounts paid to the employees as profit sharing in the period 2000 to 2004, due to the inspectors’ belief that the Company had not met the requirements described in Law 10101 of 2000. In 2007, an order of mandamus was applied for, seeking to obtain a court decision that such profit sharing payments were not subject to payment of the social security contribution. The Company received a partially favorable decision in 2008, which it has appealed and on which it awaits the second instance decision. No provision has been made for any losses, and the Company believes it has arguments of merit for defense. The amount of the contingency is approximately R$ 147,377 (R$ 140,875 on December 31, 2011). Social Security contributions The Brazilian Federal Revenue Service (Secretaria da Receita Federal) has initiated administrative proceedings against , Cemig, Cemig D and Cemig GT, in relation to social security contributions alleged to be owed on various categories of payment: – employee profit shares in profit and results (Participação nos Lucros e Resultados, or PLR); the Workers’ Food Program (Programa de Alimentação do Trabalhador, or PAT), the auxiliary education contribution (auxílio-educação), overtime payments, payment for exposure to risk in the workplace, matters related to Sest/Senat (transport workers’ support programs), and fines for non-compliance with accessory obligations. The Company has presented defenses and awaits judgment. The total of this contingency is approximately R$ 834,215 (R$ 780,723 on December 31, 2011). Refusal of offsetting of tax credits In relation to several different administrative tax proceedings dealing with offsetting of federal taxes, the Federal Revenue Service (Secretaria da Receita Federal) did not homologate tax returns offsetting credits arising from undue or excess payment by the Company. The amount of the contingency is R$ 363,308 (R$ 450,913 on December 31, 2011). Corporate tax return – restitution and offsetting The Company is a party in an administrative case involving requests for restitution and compensation of credits arising from tax carryforward balances indicated in the tax returns (DIPJs) for the calendar years 1977 to 2000, and also for excess payments identified by the corresponding tax payment receipts (DARFs and DCTFs). Due to completion of all procedures in the administrative sphere, an ordinary legal action has been filed, in the approximate total amount of R$ 396,564 (R$ 296,377 on December 31, 2011).

44 CEMIG PIS and Cofins taxes An infringement notice was served on Cemig for alleged underpayment of the PIS and Cofins taxes due to alleged exclusions of items from the taxable amounts for those taxes. In spite of the Company having paid PIS and Cofins tax on financial revenues, the Federal Revenue Department believes that these amounts were underpaid. The amount of the contingency was R$ 81,112 on December 31, 2011.The assessment of chance of loss in this contingency was altered to “remote” by our legal consultants, due to the Company believing that is has arguments of merit for its defense. The Company is defendant in various legal proceedings in which plaintiffs demand suspension of charging of PIS and Cofins taxes, on the argument that it is illegal to charge these taxes on electricity bills. The amount of the contingency was R$ 41,039 on December 31, 2011. The assessment of chance of loss was altered to “remote” by our legal consultants, due to the Company believing that is has arguments of merit for its defense. The Social Contribution tax on Net Profit The Federal Revenue Service issued an infringement notice against Cemig D for the Social Contribution tax on Net Profit (“Contribuição Social Sobre o Lucro Líquido”, or CSLL”) for the 2008 and 2009 taxation periods, contesting the constitution by Cemig D of a tax credit, based on opinions issued by its consultants and legal advisers, in relation to: donations and sponsorships of a cultural and artistic nature; punitive fines; and taxes with liability suspended. The amount of the contingency was R$ 61,745 on June 30, 2011. The assessment of chance of loss was altered to “remote” by our legal consultants, due to the Company believing that is has arguments of merit for its defense. Regulatory matters The CRC (Earnings Compensation) Account Prior to 1993, holders of electricity concessions were guaranteed a rate of return on investments in assets used to provide services linked to the concession. Tariffs charged were uniform throughout the country and the profits generated by more profitable concession holders were reallocated to the less profitable ones, in such a way that the rate of return of all the companies was equal to the national average. The deficits were accounted in the “CRC” Account of each concession holder. When the CRC Account and the guaranteed-return concept were abolished, Cemig used its positive balances in the CRC Account to offset its liabilities to the federal government. Aneel filed an administrative action against the Company, contesting a credit relating to those positive balances. On October 31, 2002 Aneel issued a final administrative decision against Cemig. On January 9, 2004, the federal Treasury Department (Secretaria do Tesouro Nacional) issued a collection notice in the amount of R$ 516 million. The Company did not make the payment, because it believes that it has

45 CEMIG arguments of merit for defense in court, and filed for an order of mandamus to suspend its inclusion in the Listing of Unpaid Public Sector Debts (Cadin). The order of mandamus was denied by the lower court, but an appeal was made to the Federal Court of the First Region, which granted Cemig a temporary injunction suspending inclusion in the Cadin. No provision has been constituted in relation to this action. The estimated amount of the contingent liability is R$ 1,050,206 (R$ 1,014,905 on December 31, 2011. Contribution for Public Illumination (CIP) Cemig is defendant in several class actions, claiming nullity of the clause in Electricity Supply Contracts for public illumination, signed between the Company and the various municipalities of its concession area, and restitution by the Company of the difference representing the amounts charged in the last 20 years, in the event that the courts recognize that these amounts were unduly charged. The actions are grounded on an alleged mistake by Cemig in the estimate of time used for the calculation of the consumption of electricity by public illumination paid for by the Public Illumination Contribution (CIP). The Company believes that it has arguments of merit for legal defense, and as a result has not constituted a provision for this action, the amount of which is estimated at R$ 1,177,216 (R$ 1,183,402 on December 31, 2011) . Accounting of electricity sale transactions in the Electricity Trading Chamber (CCEE) In an action dating from August 2002, AES Sul Distribuidora challenged, in the courts, the criteria for accounting of electricity sale transactions in the Wholesale Electricity Market (Mercado Atacadista de Energia, or MAE), the predecessor of the Electricity Trading Chamber (Câmara de Comercialização de Energia Elétrica, or CCEE), during the period of rationing. It obtained an interim judgment in its favor in February 2006, ordering Aneel to comply with AES Sul’s request and, together with the CCEE, reaccount, and settle, the transactions during the rationing period, leaving Aneel’s Dispatch 288 of 2002 out of account. This measure was to be put into effect in the CCEE starting in November 2008, and would have resulted in an additional disbursement for the Company, for expense on purchase of energy in the spot market in the CCEE, of approximately R$ 132,429 (R$ 123,900 on December 31, 2011). On November 9, 2008 the Company obtained interim relief from the Regional Federal Appeal Court (Tribunal Regional Federal, or TRF) suspending the obligation to deposit the amount owed, due to the Special Financial Settlement carried out by the CCEE. Because of this, no provision has been made for this dispute, since the Company believes it has arguments on the merit for defense against this claim.

46 CEMIG Tariff increases Exclusion of consumers inscribed as Low-income The Federal Public Attorneys’ Office filed a class action against the Company and Aneel, to avoid exclusion of consumers from classification in the Low-income Residential Tariff sub-category, requesting an order for the Company to pay 200% of the amount allegedly paid in excess by the consumers. The court ruled in favor of the plaintiff; the Company and Aneel have filed an interlocutory appeal, and await judgment. The amount of this contingency is approximately R$ 130,236 (R$ 122,531 on December 31, 2011). Period Tariff Adjustment – Neutrality of “Portion A” The Municipal Association for Protection of the Consumer and the Environment (Amprocom) and the Brazilian Consumers’ Association (ABC) filed actions against the Company and against Aneel, for identification of all the consumers that were allegedly injured in the processes of periodic review and annual adjustment of electricity rates, from 2002 through 2009, and restitution, through credit on electricity bills, of the amounts allegedly unduly charged, due to the non-inclusion of the effect of future variations in consumer electricity demand as a component of the distributor’s nonmanageable costs (“Portion A”), and their allegedly undue inclusion in manageable costs (“Portion B”), resulting in economic/financial imbalance of the contract. The amount of the contingency is R$ 156,306 (R$ 1,061,804 on December 31, 2011). Tax contingencies of Light Sesa Light Sesa has the following tax contingencies in which the chances of loss are assessed as “probable”: . Demand for payment of corporate income tax and the Social Contribution tax on profits reported by the companies LIR and LOI since 1996 (on August 7, 2012, the Administrative Council for Tax Appeals (Conselho Administrativo de Recursos Fiscais, Carf) cancelled this claim, the quantifiable amount of which was R$ 172,924 – an amount corresponding to the entire value of Cemig’s equity share in Light). . Fine for alleged non-compliance with an accessory obligation relating to delivery of the electronic files for the calendar years 2003 to 2005. . An infringement notice issued to charge ICMS tax on amounts of the subsidy directed to low-income consumers. . ICMS tax on commercial losses. . Charge for Inspection of Occupation of Public Spaces (Taxa de Fiscalização de Ocupação e de Permanência em Áreas, em Vias e em Logradouros Públicos, or TFOP), made by the municipal prefecture of Barra Mansa. . IRRF on amounts paid by Light Sesa as dividends, on the argument that they arose from non-existent profit. . Infringement notice demanding ICMS tax, arising from the use of accumulated ICMS tax credits of Rheem Embalagens Ltda. in the acquisition of inputs and raw materials within the State of Rio de Janeiro. . Non-inclusion of offsetting made to settle debits of Cofins tax.

47 CEMIG The proportionate part of the total of these cases corresponding to Cemig’s percentage interest in the share capital of Light is R$ 981,073 (R$ 859,568 on December 31, 2011). Claims in the Ordinary Course of Business In addition to the issues described above, the Company is involved, on the plaintiff or defendant side, in other cases, of smaller scale, related to the normal course of business, in an estimated total amount of R$ 736,498 (R$ 523,362 on December 31, 2011). Management believes that it has adequate defense for these actions, and does not expect significant losses, relating to these disputes, such as might have an adverse effect on the Company’s financial position or the result of its operations. Action in which the Company is creditor and in which economic benefits are probable Pasep and Cofins taxes – Widening of the calculation base The Parent Company brought legal proceedings challenging the expansion of the taxable basis for calculation of the Pasep and Cofins taxes, on financial revenue and on other non-operational revenues, in the period from 1999 to January 2004, by Law 9718 of November 27, 1998. In the event that this action is won in the final instance (i.e. when subject to no further appeal) – and we note that the Federal Supreme Court has ruled on similar proceedings in favor of the taxpayer – the gain to be posted in the Profit and loss account will be R$ 201,041 (R$ 195,263 on December 31, 2011), net of income tax and Social Contribution Tax. 21. SHAREHOLDERS´EQUITY The Company’s share capital on September 30, 2012 is R$ 4,265,091, in 372,837,085 common shares and 480,181,143 preferred shares, with nominal value of R$ 5.00. Capital increase to be proposed to the Annual Shareholders’ Meeting in April 2012 The General Meeting of Stockholders of Cemig held on April 27, 2012 approved increase in the share capital of Cemig from R$ 3,412,073 to R$ 4,265,091, with issuance of 170,603,646 new shares, via capitalization of R$ 821,527 of the Retained Earnings Reserve, and R$ 31,491 originating from incorporation of the portions of the contract to assign the credit of the remaining balance on the CRC Account, with distribution, as a result, to stockholders of a stock bonus of 25% in new shares of the same type as those held, and with nominal value of R$ 5.00. Earnings Per Share The two types of share – common and preferred – have equal status in distribution of profit. Profit per share was R$ 2.80 in 3Q12, and R$ 2.50 in 3Q11. (These figures are based on the weighted average of the number of shares in each of the years.)

48 CEMIG The calculation of the weighted average number of shares used in the calculation of basic profit and diluted profit per share is as follows: Calculation of weighted average number of shares Sep. 30, 2012 Sep. 30, 2011 Numbers of shares at January 1 Common shares 298,269,668 298,269,668 Preferred shares 384,144,914 384,144,914 682,414,582 682,414,582 Effect of issuance of shares in April 2012 Common shares 74,567,417 - Preferred shares 96,036,229 - 170,603,646 - Weighted average number of shares at September 30 Common shares 339,696,011 298,269,668 Preferred shares 437,498,375 384,144,914 777,194,386 682,414,582 The Company has no instruments giving rise to dilution. Hence the diluted profit is equal to the basic profit. 22.

49 CEMIG Tariff Adjustment of Cemig D On April 8, 2012 Aneel approved the result of the Tariff Adjustment for Cemig D. The result approved by Aneel was for an upward adjustment of 5.24%, made up of two components: (i) The Structural component, of 2.90%, comprising the non-manageable costs (“Portion A”) and manageable costs (“Portion B”); and (ii) Financial components, of 2.34%. The adjustment is in effect until April 2013. With the withdrawal of the financial components considered in the 2011 tariff process, of 2.39%, the average effect on the Company’s captive consumers was an increase of 3.85% (this figure has not been audited). b) Other operational revenues Consolidated Sep. 30, 2012 Sep. 30, 2011 Supply of gas 546,593 421,989 Charged service 13,688 11,230 Telecoms services 121,786 117,186 Providing of services 96,832 76,325 Renting 73,098 46,727 Low-income subsidy (*) 123,796 63,636 Other 6,550 1,388 982,343 738,481 (*) Revenue recognized for the subsidy received from Eletrobrás, for the discount given on tariffs charged to lowincome consumers.

The Company has a Financial Risks Management Committee, the purpose of which is to implement guidelines and monitor the financial risk of transactions that could negatively affect the Company’s liquidity or profitability, recommending hedge protection strategies to control the Company’s exposure to foreign exchange rate risk, interest rate risk, and inflation risks. These protection strategies are in accordance with the Company’s overall strategy. A key aim of the Financial Risks Management Committee is to give predictability to the Company’s cash flow for a maximum period of 12 months, taking into account the economic scenario published by a firm of external consultants. The principal risks to which the Company is exposed are as follows:

57 CEMIG Exchange rate risk Cemig and its subsidiaries and jointly-controlled subsidiaries are exposed to market risk from adverse changes in foreign currency rates, primarily of the US dollar against the Brazilian Real, which could potentially have impact on debt, profit and cash flow. To reduce exposure to adverse changes in exchange rates the Company held certain hedge contracts on September 30, 2012 and 2011, described in more detail in item “b” below. These tables indicate the net exposure to exchange rates: EXPOSURE TO EXCHANGE RATES Consolidated Sep. 30, 2012 Dec. 30, 2011 US dollar Loans and financings 451,475 318,947 Suppliers – Eletrobras – Electricity from Itaipu 223,990 198,280 (+/–) Contracted hedges / swaps (28,206) (32,312) 647,259 484,915 Other foreign currencies Loans and financings – Euro 38,032 37,299 UMBndes ( ** ) 2,602 2,661 Net liabilities exposed 40,634 39,960 687,893 524,875 ( ** ) UMBndes = BNDES Monetary Unit. Exchange rate sensitivity analysis The Company and its subsidiaries and jointly-controlled subsidiaries estimate that in a probable scenario, depreciation of the exchange rates of foreign currencies against the Brazilian Real on September 30, 2012 will be: 1.38% for the US dollar (to R$ 2.003) and 4.63% for the Euro (to R$ 2.490). The Company has performed a sensitivity analysis showing the effects on the Company’s profit of depreciation of the Real of an additional 25% and 50% as compared to the “probable” scenario – designating these alternative scenarios as “Possible” and “Remote”, respectively.

58 CEMIG floating interest rates (principally Libor), in the amount of R$ 297,973 on September 30, 2012 (R$ 207,489 on December 31, 2011). In relation to the risk of increase in domestic Brazilian interest rates, the Company’s exposure arises from net liabilities indexed to the Selic and CDI rates, as follows: Exposure to domestic interest rate changes Consolidated Sep. 30, 2012 Dec. 30, 2011 Assets Cash equivalents – Short-term investments (Note 4) 2,371,975 2,704,600 Securities (Note 5) 2,341,151 358,987 Linked funds 24,837 3,386 4,737,963 3,066,973 Liabilities Loans, financings and debentures – Selic rate (Note 18) (8,982,434) (9,274,474) Loans, financings and debentures – IPCA index (Note 18) (3,231,790) (2,249,647) Loans, financings and debentures – IGP–M index (Note 18) (460,275) (443,018) Contracted interest rate hedges and swaps (600,000) (600,000) Contracted foreign exchange rate hedges and swaps (28,206) (32,312) (3,826,779) (12,599,451) Net liabilities exposed (8,564,742) (9,532,478) Sensitivity analysis In estimating risk related to the most important interest rates, the Company and its subsidiaries estimate that in a “probable” scenario, on September 30, 2013 the Selic rate, and the IPCA and IGP-M inflation indices will be, respectively, 7.25%, 5.56% and 4.07%. The Company has performed a sensitivity analysis to show the adverse financial effects which would occur in scenarios assuming an additional 25% and 50% increase in the Selic rate compared to the increase assumed in the “probable” scenario – designating these alternative Selic rate increase scenarios as “Possible” and “Remote,” respectively. Variation in the CDI rate accompanies the variation in the Selic rate. Estimation of the scenarios for the path of interest rates will consider the projection of the Company’s basic, optimistic and pessimistic scenarios, based on opinions from its financial consultants, as described in the Hedging Policy.

59 CEMIG Credit Risk The risk resulting from losses on doubtful receivables for CEMIG and its subsidiaries is considered to be low. The Company carries out monitoring for the purpose of reducing default, on an individual basis, with its consumers. Negotiations are also entered into for receipt of any receivables in arrears. The allowance for doubtful debtors constituted on September 30, 2012, considered to be adequate in relation to the credits in arrears receivable by the Company and its subsidiaries and jointly-controlled subsidiaries, was R$ 109,420. In relation to the risk of losses arising from insolvency of the financial institutions at which the Company, its subsidiaries or jointly-controlled subsidiaries have deposits, a Cash Investment Policy was approved and has been in effect since 2004, in which each institution is analyzed for risk purposes according to criteria of current liquidity, degree of leverage, degree of default, profitability, and costs. Additionally, the Company takes into consideration the ratings given to the financial institutions by three financial risk rating agencies. The Company assigns each financial institution a maximum fund allocation limit, which is reviewed for appropriateness both periodically and also in the event of any change in the macroeconomic scenarios of the Brazilian economy. Cemig manages the counterparty risk of financial institutions based on an internal policy approved by its Financial Risks Management Committee. This Policy assesses and scales the credit risks of the institutions, the liquidity risk, the market risk of the investment portfolio and the Treasury operational risk. All investments are made in financial securities that have the characteristics of fixed income, and are always indexed to the CDI rate. As a management instrument, Cemig divides the investment of its funds into: direct purchases of securities (own portfolio); and three investment funds, which hold approximately 20% of the total portfolio. These investment funds invest the funds exclusively in fixed income products, and companies of the Group are the only unit holders. They obey the same policy adopted in the investments of the Company’s own portfolio. The minimum requirements of the Company and its principal subsidiaries for concession of credit to financial institutions are centered on three items: 1. Rating by two risk rating agencies. 2. Stockholders’ equity greater than R$ 400 million. 3. Basle ratio: 12 or above. Exceeding these thresholds, banks are classified in three groups, by the value of their Stockholders’ equity. From this classification as a starting point, limits of concentration by group and by institution are established:

60 CEMIG Group Stockholders’ equity Concentration Limit per bank (% of Stockholders’ equity )** Federal government risk - Maximum 50% 7.,0% A1 Over R$ 3.5 billion Between 2.8% and 7.0% A2 R$ 1.0bn to R$ 3.5bn Maximum 30% Between 2.8% and 7.0% B R$ 400mn to R$ 1.0 bn Maximum 20% Between 1.6% and 4.2% ** The percentage assigned to each bank depends on an individual assessment of indicators such as liquidity, quality of the credit portfolio, and other aspects. As well as these points, Cemig also establishes the following concentration limits: 1. No bank may have more than 30% of the Group’s portfolio. 2. No bank may have more than 50% of the portfolio of a Company. Risk of early maturity of debt The Company, and its subsidiaries and jointly-controlled subsidiaries, have contracts for loans and financings with restrictive financial covenant clauses normally applicable to these types of transaction, related to complying with economic and/or financial indices, cash flow and other indicators. Non-compliance with these covenants could result in early maturity of debts. These covenants require compliance every six months, as described in Explanatory Note 17 to the Interim Financial Statements. Liquidity risk Cemig has sufficient cash flow to cover its short-term requirements and also for its program of acquisitions and investments. Management of liquidity risk is as important as the quality of management of the business’s operational cash flow, and the Company uses a group of methodologies, procedures and instruments that are coherent with the complexity of the business, which it applies in permanent control of the financial processes, to guarantee appropriate risk management. The processes of management of corporate risks interact with other instances of management, including: The Corporate Governance Committee, the Budget Prioritization Committee, the Energy Risks Management Committee, the Insurable Risks Committee, the Control and Management Committee, and the Financial Risks Management Committee. The structure also provides measures to perform internal auditing functions and to ensure compliance with the requirements of the Sarbanes- Oxley Law. The Financial Risk Management Committee, in particular, has as its purpose the implementation of directives to control the financial risk of transactions that could compromise the Company’s liquidity and profitability.

61 CEMIG Cemig manages liquidity risk by permanently monitoring its cash flow in a conservative, budget-oriented manner. Balances are projected monthly, for each one of the companies, over a period of 12 months, and daily liquidity is projected over 180 days. Short-term investments similarly follow rigid principles, established in the Investment Policy: up to 20% of the funds are in exclusive private credit investment funds, without market risk, and the remainder is invested directly in bank CDs or repo contracts which earn interest at the CDI rate. In managing cash investments, the Company seeks to obtain profitability on the transactions through rigid analysis of financial institutions’ credit, obeying operational limits with banks based on assessments of the financial institutions’ ratings, risk exposures and equity position. It also seeks greater returns on investments by strategically investing in securities with longer investment maturities, while bearing in mind the Company’s minimum liquidity control requirements.

The derivative financial instruments are not used for speculative purposes.

62 CEMIG The amounts of the principal of derivative transactions are not presented in the balance sheet, since they refer to transactions that do not require cash principal payments to be made: only the gains or losses that actually occur are recorded. On September 30, 2012 the net result of the gains and losses on derivative instruments was a gain of R$ 25,054 (vs. a gain of R$ 16,338 on September 30, 2010). This gain is recorded in Financial revenue (expenses). The Company has a Financial Risks Management Committee, which was created to monitor the financial risks in relation to volatility and trends of inflation indices, exchange rates and interest rates that affect its financial transactions and which could adversely affect its liquidity and profitability. The Committee implements action plans to set guidelines for proactive operation in the environment of financial risks. The Company has derivative instruments contracted by its indirect subsidiary Unisa, which is controlled jointly by Taesa. The purpose of these derivatives is to protect its operations against risks of variation in exchange rates; they are not used for speculative purposes. Through the operations contracted by Unisa, the Company is exposed to the variation in the exchange rate under two types of financings from the InterAmerican Development Bank linked either in part to a basket of currencies or to the US dollar. To mitigate the effects of the variation of the exchange rate, Unisa used derivative hedge instruments and contracted purchase options during the business year. Through the indirect jointly-controlled subsidiary Madeira, the Company has a cash flow hedge to protect the exposure to variability in cash flows attributable to a risk associated with an asset or liability or a highly probable future transaction which might significant affect the Company’s profit. The subsidiary carries out analyses quarterly, to assess the effectiveness of the hedge transactions. The derivatives designated as “cash flow hedges”, and which qualify for hedge accounting, are required to be duly documented for this purpose. The Company considers instruments that offset between 80% and 125% of the change in price of the item for which the hedge protection was contracted, to be highly effective. The Company has derivative instruments contracted by its subsidiary Light. The purpose of these derivatives is to protect its operations against risks of variation in exchange rates; they are not used for speculative purposes. Some of the loans and financings of the indirect subsidiary Light Sesa are denominated in foreign currency, Light Sesa uses derivatives (swap transactions) to protect the servicing associated with those debts (principal plus interest and fees) becoming due in up to 24 months, as well as the rate swaps previously referred to.

63 CEMIG Method of calculation of the fair value of positions The fair value of cash investments has been calculated taking into consideration the market values of each security, or market information available to perform such a calculation, and the future interest rates and foreign exchange rates applying to similar securities. The market value of the security represents its value at maturity, discounted to present value using the factor obtained from the market yield curve in Reais. The table below shows the derivative instruments contracted by the subsidiaries Cemig Distribuição, Madeira Energia, Taesa and Light as of September 30, 2012.

The contracts are exchange rate and indexor swaps.

64 CEMIG Sensitivity analysis The derivative instrument described above shows that the Company and its subsidiaries are exposed to variation in the CDI rate. Based on opinions of its financial consultants, the Company estimates that, in a “Probable” scenario, on September 30, 2013 the CDI rate will be 7.25%, and the US dollar will have depreciated against the Real by 1.38% (to R$ 2.003/US$). The Company has performed a sensitivity analysis to demonstrate the adverse financial effects on its profit that would occur in scenarios assuming further changes in the CDI rate and the exchange rate of 25%, and 50%, in that period – designating these scenarios as “Possible” and “Remote,” respectively. In the “Possible” scenario, the CDI rate at December 31, 2013 would be 9.06%, and in the “Remote” scenario it would be 10.88%. Risks of variation of the CDI rate, in relation to the Base Scenario Base scenario Sep. 30, 2012 “Probable” scenario “Possible” scenario “Remote” scenario Risk – Increase in Brazilian domestic interest rates Contracts updated at 100.00% of CDI rate 28,206 30,251 30,761 31,275 Net effect of the variation in the CDI rate (2,045) (2,555) (3,069) Risk: Increase in US$ exchange rate Contracts updated at 100.00% of CDI rate 28,206 27,817 34,771 41,726 Net effect of variation of US$ 389 (6,565) (13,520) Net effect (2,434) 4,010 10,451 Risk of variation of the CDI rate in relation to a fixed rate of 11.47% p.a.

FAIR VALUE MEASUREMENTS In the initial posting, the Company classifies its assets and liabilities at fair value. After the initial posting, it classifies financial assets and liabilities between the four categories defined for financial instruments. Fair value is measured as market value based on assumptions in which market participants are able to price an asset or liability. The fair value hierarchy aims to increase consistency and comparability: it prioritizes the inputs used in measurement of value into three broad levels: . Level 1: Active market – Quoted price: A financial instrument is considered to be quoted on an active market if the quoted prices are promptly and regularly made available by an exchange or by an organized over-the-counter market, or by traders, brokers, a market association, entities whose purpose is to publish prices, or regulatory agencies, and provided that these prices represent market transactions that occur regularly in arm’s length transactions between independent parties. . Level 2: No active market – Valuation technique: For an instrument that does not have an active market, fair value should be found by using a method of valuation/pricing. Criteria such as data on the current fair value of another instrument that is substantially similar, or discounted cash flow analysis or option pricing models, may be used. The objective of the valuation technique is to establish what would be the transaction price on the measurement date in an arm’s-length transaction motivated by business considerations. . Level 3: No active market – Securities: Fair value of investments in securities for which there are no prices quoted on an active market, and of derivatives linked to them which are to be settled by delivery of unquoted securities.

66 CEMIG This is a summary of the instruments that are measured at fair value: Item Balance on September 30, 2012 Fair value at September 30, 2012 Level 1: Active market – quoted price Level 2: No active market – valuation technique Level 3: No active market – Equity security Assets Securities Bank certificates of deposit 579,017 - 579,017 - Treasury Financial Notes (LFTs) 66,404 66,404 - - National Treasury Notes (NTNs) 79,592 79,592 - - Financial Notes – Banks 89,749 - 89,749 - Fixed income market 186,367 - 186,367 - Others 143,275 - 143,275 - 1,144,404 145,996 419,391 - Linked funds 24,837 - 24,837 - Swap contracts 28,206 - 28,206 - Method of calculation of the fair value of positions . The fair value of cash investments is calculated taking into consideration the market prices of the security, or market information that makes such calculation possible, the future fixed-income market and FX rates applicable to similar securities. The market value of the security is its maturity value discounted to present value by the discount factor obtained from the market yield curve in Reais. . Swap contracts: The criterion for marking derivative instruments to market consists of establishing the present value of a transaction contracted in the past in such a way that its replacement provides the same results as a new transaction. Swaps are priced by calculating the difference between the market values of each one of their end points, adjusted by their indexor. A Swap contract based on the CDI (Interbank Certificate of Deposit) rate is priced as calculated from the start date of the transaction up to the specified future date, considering the future forecast for this indexor. Pricing of the dollar side of the Swap is adjusted by the variation in the exchange rate, using a future expectation and an embedded risk premium.

67 CEMIG 28. STATEMENTS OF ADDED VALUE The Company has prepared individual and consolidated statements of added value. This is in accordance with a requirement by the CVM, applicable to listed companies; and in relation to IFRS, its status is that of additional information. These statements, founded on macroeconomic concepts, seek to present the contribution of the Group in the formation of Gross Domestic Product, by calculating the added value both created by the Group and received from other entities, and the distribution of these amounts to its employees, spheres of government, lessors of assets, creditors under loans, financings and debt securities, controlling and noncontrolling stockholders, and other remunerations that characterize transfer of wealth to third parties. The added value referred to represents the wealth created by the Group, as a whole, measured by the revenues from sales of goods and of services provided, less the respective inputs acquired from other parties, also including the added value produced by other parties and transferred to the entity. 29. RENEWAL OF CONCESSIONS: PROVISIONAL MEASURE 579 OF SEPTEMBER 11, 2012 On September 11, 2012 the Brazilian federal government issued Provisional Measure 579 (“PM 579”), which makes provisions governing: electricity generation, transmission and distribution concessions; reduction of the sector charges; moderation of tariffs; and other matters. With PM 579, the government aimed to close the debate on whether those electricity concessions that are referred to by Articles 17, §5, 19 and 22 of Law 9074, of July 7, 1995 and have expiry dates in 2015 or later could be extended for a further 20 years, under the terms set out in that Law and in the respective Concession Contracts; or whether they would be put out to tender. PM 579/2012, when dealing with the extensions of concessions for electricity distribution, transmission and generation covered by the articles listed above, imposed new conditions on the concession holders for extension, allowing extension for a period of 30 years. Under these new conditions (i) the expiry dates of those concessions would be brought forward, and (ii) concession holders would sign Amendments to their Concession Contracts with the Concession-granting Power, establishing the new conditions.

68 CEMIG The extension referred to also depends on express acceptance by the concession holder of the criteria for remuneration, allocation of energy, and standards of quality contained in PM 579; and PM 579 also specifies the amounts of indemnity for assets not yet amortized or depreciated: these are to be based on New Replacement Cost Value (valor novo de reposição, or VNR) – with the exception of the transmission assets that existed on May 31, 2000, which are deemed to be totally amortized. Finally, all concessions that are not extended under the terms of PM 579 will be offered by tender, either by auction or through competitive bids, for up to 30 years. Cemig operates, through its subsidiaries and affiliated companies, the following assets which will be to a greater or lesser extent affected by the measures announced: – approximately 7 GW of installed generation capacity; – 5,000 km of transmission lines; and – 490,000km of electricity distribution networks. In compliance with the provisions of PM 579, on October 15, 2012 Cemig submitted to Aneel its statement of interest in extending those concession contracts for generation, transmission and distribution of electricity which are, in the Company’s understanding, within the criteria of PM 579, without prejudice to any rights that it may have under the resulting law eventually legislated by Congress based on that Provisional Measure. In keeping with the timetable set by PM 579, Mining and Energy Ministry (MME) Ministerial Orders 578 and 579, of October 31, 2012, set out initial tariffs for the hydroelectric plants affected by PM 579, and also the initial electricity transmission revenues for facilities covered by its Article 6, for concessions extended by its process. And on November 1, 2012, Joint Order 580 of the Mining and Energy and Finance Ministries laid down the values of indemnities to be paid to holders of generation and transmission contracts that opt to accept early extension of their concessions.

69 CEMIG Cemig applied for renewal of the following concession contracts: 1. Distribution: Concessions for public electricity distribution services governed by the following Distribution Concession Contracts: 002/97 – Cemig Norte; 003/97 – CEMIG Sul; 004/97 – Cemig Leste; and 005/97 – Cemig Oeste; – all dated July 10, 1997, and given under DNAEE Ministerial Order 130 of April 17, 1997, published in the federal Official Gazette of April 22, 1997, and extended by Ministerial Order 125 of April 17, 1997 issued by the Mining and Energy Ministry, published in the federal Official Gazette on April 22, 1997. On September 30, 2012, the Company has intangible and financial assets registered in the amount of R$ 6,489,256 referring to these distribution contracts. In relation to the concessions for distribution, to enable it to decide on the extension of the concessions, the Company is awaiting the statement of position by the Concession-granting Power which will define the next stages related to the extension of these contracts. According to a working timetable for tariff reduction published by the announcement on Aneel’s site on September 13, 2012, the decision on the next stages will take place as from December 19, 2012.

70 CEMIG 2. Generation: Concessions for electricity generation service provided by the generation plants listed below, contained in Concession Contract 007/97– Cemig Geração, with provisos relating to the price of electricity, residual value of the assets and operating conditions. For these concessions, MME Interministerial Order 580 states that there is to be no indemnity by the Concession-granting Power. The values of the tariffs proposed, and the net balance of asset value in these generation plants as measured by the deemed cost (the basis of reporting by the Corporate Law accounting method) and by the historic cost, are as follows: Generating plants Rate published in MME Order 578/12: R$/kW.year Corresponding rate in R$/MWh Net value of asset based on historical cost at Sep. 30, 2012, (THOUSANDS OF R$) Net value of asset based on deemed cost at Sep. 30, 2012, (THOUSANDS OF R$) Hydroelectric Plants Três Marias 58.48553 11.06220 54,641 462,838 Volta Grande 59.08092 11.19158 30,183 86,710 Salto Grande 89.27921 13.86070 10,178 45,588 Itutinga 94.88619 20.11612 3,011 10,745 Camargos 92.23039 23.06261 4,936 23,444 Small Hydro Plants Piau 140.93844 21.41614 1,650 12,974 Gafanhoto 127.51929 30.50868 2,033 17,367 Peti 158.8735 27.58587 1,345 10,177 Tronqueiras 146.19005 34.26354 2,125 14,613 Joasal 160.02056 29.50853 1,721 10,707 Martins 129.76072 45.08264 472 3,395 Cajuru 152.18112 35.94264 4,113 4,997 Paciência 188.19722 37.14131 1,146 5,866 Marmelos 204.86441 32.48104 994 6,529 Dona Rita 193.26319 51.62081 674 4,099 Sumidouro 139.73608 99.46296 2,201 1,719 Anil 216.85424 46.80955 269 365 Poquim 251.18478 Under study 2,341 4,795 124,033 726,928 Note: The amounts for the deemed cost were recorded at the time of adoption of the new accounting rules in accordance with IFRS, on January 1, 2009. The difference between the amount of the deemed cost and the historical cost is posted directly in a specific line of the Company’s equity, without this initial reporting having an effect on the Company’s reported profit. For the concessions of the Jaguara, São Simão and Miranda generation plants, the concessions for which have expiry dates in August 2013, January 2015 and December 2016, respectively, the Company believes that it has the right to extension of the concessions under the conditions prior to PM 579, under clauses established in the concession contracts and Article 19 of Law 9074/1995. On September 30, 2012 the aggregate historical cost of these plants was R$ 1,044,166; and the aggregate deemed cost was R$ 1,334,511.

71 CEMIG 3. Transmission: Concession for public electricity transmission service, under Concession Contract 006/97 – Cemig, referring to the transmission facilities under its responsibility classified as part of the National Grid, in accordance with Law 9074/95 and related regulations, with provisions referring to the authorized revenue, operational conditions and residual value of the assets. The indemnity specified in Interministerial Order 580 for the Company’s transmission assets was R$ 285,438, while the annual revenue laid down in MME Ministerial Order 579 was R$ 148,536. On September 30, 2012, the Company has financial assets recorded in the amount of R$ 722,732 relating to Contract 006/97. Under PM 579 the Company has until December 4, 2012 to state its opinion on agreement with the tariffs laid down for the generation and transmission concessions referred to, and on the amount of the indemnity specified for the purposes of signature of the renewal of the concession contracts. If the Company does not accept the terms specified by the Concession-granting Power, it will maintain the operation of the assets until the end of the period of each one of the concessions referred to, supported by the concession contracts that are still in effect. Since the Company has not yet made any final statement of position on acceptance of the conditions laid down in PM 579 for early renewal of its concessions and the assessment of the indemnity specified, it is not possible at present to determine the future financial effects of PM 579 on its Financial Statements. 30. SUBSEQUENT EVENTS Payment of dividends by Light On October 11, 2012, Light made payment of dividends relating to the profits for the 2011 business year and to part of the capital reserve existing in the balance sheet at December 31, 2011, approved by the Annual General Meeting held on April 11, 2012, in the amount of R$ 181,501.

72 CEMIG Partial extraordinary amortization of the 5th Debenture Issue of Light Sesa On October 8, 2012 the indirect subsidiary Light Sesa carried out partial extraordinary amortization of its fifth debenture issue, in the amount of R$ 375,000. Tariff Review of Light SESA At a public meeting held on November 6, 2012 Aneel approved the result of the 2012 Tariff Adjustment for the subsidiary Light SESA. The result homologated by Aneel represents a tariff adjustment of 10.77%, made up of two components: (i) a structural component of 7.17%, comprising the non-manageable costs (“Portion A”) and the manageable costs (“Portion B”); and (ii) a financial component, which will be in effect for the next 12 months, of 3.60%. Including the effect of withdrawal of the financial component that was present in the tariffs of Light in effect up to that date, of –0.64%, the average increase for consumers will be 11.41%, as from November 7, 2012 Note that the effects arising from Provisional Measure 579 (of September 11, 2012) are not included in this tariff adjustment, since the tariff reduction specified in it will be applied only as from February 5, 2013, when Aneel will carry out Extraordinary Tariff Reviews of all the holders of electricity concessions in Brazil.

75 CEMIG 32. INFORMATION BY OPERATIONAL SEGMENT PERIOD ENDED SEPTEMBER 30, 2012 (R$ ’000) The operational segments of Cemig reflect the structure of the regulatory framework for the Brazilian electricity sector, with different legislation for the sectors of generation and transmission. The Company also operates in the markets of gas, telecommunications and other businesses, which have a smaller impact on the results of its operations. The segments mentioned above are reflected in the Company’s management and organizational structure, and its structure for monitoring results. The operational results are regularly reviewed by the principal managers of the Company’s operations, with separate consideration of the operational segments of Generation and Transmission for the taking decisions on funds to be allocated to these segments and individual assessment of their performance. In accordance with the regulatory framework of the Brazilian electricity sector, there is no segmentation by geographical area.

77 77 CEMIG CONSOLIDATED ECONOMIC AND FINANCIAL PERFORMANCE (Figures in R$ ‘000, except where otherwise indicated) 1. January–September 2012 (9M12) Profit for 9M12 Cemig’s consolidated profit for the first nine months of 2012 (9M12) was R$ 2,172,751, 27.33% higher than the profit for the first nine months of 2011 (9M11) of R$ 1,706,455. A significant element in the difference was recognition of gains in value totaling R$ 258,705, on issuance of shares, arising from the Public Offering of Shares by Taesa, an indirectly-held subsidiary of Cemig GT; and from capitalization of Renova, an indirect subsidiary of Light. See Note 12. Another factor in the better result in 2012 was revenue 16.99% higher, partially offset by Operational costs and expenses 19.41% higher. The principal changes in levels of revenue, costs and expenses are presented below in this report. EBITDA Cemig’s consolidated Ebitda was higher in 2012 in the first nine months of 2012 (9M12) than in 9M11: EBITDA - R$ ’000 Sep. 30, 2012 Sep. 30, 2011 (Reclassified) Change, % Net profit for the year 2,172,751 1,706,455 27.33 + Provision for income tax and Social Contribution tax 935,644 821,048 13.96 + Financial revenue (expenses) 803,999 765,909 4.97 + Amortization and depreciation 711,952 724,779 (1.77) = EBITDA 4,624,346 4,018,191 15.09 Ebitda 4.018 4.624 0% 10% 20% 30% 40% 50% - 1.000 2.000 3.000 4.000 5.000 Jan a Set/11 Jan a Set/12 LAJIDA – R$ mil Margem LAJIDA - % Ebitda, R$ bn Ebitda margin, %

78 CEMIG Higher Ebitda in 9M12 than 9M11 was mainly due to the gain on issuance of shares, referred to above, and to revenue 16.99% higher year-on-year (YoY), partially offset by Operational costs and expenses 21.49% higher YoY (excluding the effects of depreciation and amortization). The higher Operational costs and expenses in 9M12 were reflected in Ebitda margin, which was 34.58% in 9M12, compared to 35.15% in 9M11. Supply of electricity: volume and revenue Revenue from all supply of electricity in 9M12 was R$ 13,636,459, 12.03% more than in 9M11 (R$ 12,172,039). Final consumers Revenue from sales of electricity to final consumers (excluding own consumption) totaled R$ 12,271,478 in 9M12, 12.22% more than in 9M11 (R$ 10,935,119). The main factors in this result are: . Volume of energy invoiced to final consumers (excluding Cemig’s own consumption) 3.81% higher. . Tariff increase for Cemig D, with average effects on consumer tariffs of 7.24%, effective from April 8, 2011 (having full-year effect in the 2012 accounts). . Tariff increase for Cemig D, with average effects on consumer tariffs of 3.85%, effective from April 8, 2012. . Tariff increase for Light, with average effects on consumer tariffs of 7.82%, in effect from November 7, 2011. . Contractual increase in the rates paid by Free Consumers, indexed mainly by the IGP-M inflation index.

79 79 CEMIG The reason for consumption by the industrial user category being 0.46% lower was the lower level of industrial activity. This effect was offset by the increase in two consumer groups – (i) Commercial, services and others, and (ii) Rural – mainly reflecting the increase in their quantity of consumers: 7.35%, and 15.80%, respectively. In addition to the increase in the number of rural consumers, there was a significant increase in the demand for electricity for irrigation, due to the atypical climatic conditions for the wet period, with lower levels of rain in February to May. Revenue from wholesale electricity sales Although the quantity of electricity sold to other concession holders was 2.87% lower YoY in 9M12, the revenue from electricity sold was 11.42% higher – at R$ 1,315,319 in 9M12, compared to R$ 1,180,555 in 9M11 – due to the average sale price of electricity in 9M12, at R$ 128.97/MWh, being 14.71% higher than in 9M11 (R$ 112.43/MWh. Revenue from use of the electricity distribution systems (TUSD) The revenue earned by Cemig D and Light in 9M12 was R$ 1,559,508, 6.47% more than in 9M11 (1R$ 1,464,781) This revenue comes from charges made to Free Consumers on the electricity sold by other agents of the electricity sector. Its higher total in 2012 arises from a higher volume of transport of electricity for Free Consumers, mainly a consequence of migration of captive clients to the Free Market. Transmission Concession Revenue For the older concessions, Transmission Concession Revenue refers to the tariff charged to agents in the electricity sector, including Free Consumers connected to the high voltage network, for use of the National Grid, less the amounts received that are used for amortization of the financial asset. For the new concessions, it includes the portion received from agents of the electricity sector relating to operation and maintenance of the transmission lines and also the adjustment to present value of the Transmission Financial Asset constituted, primarily, during the period of construction of the transmission facilities. The rates used for updating of the asset correspond to the remuneration on the capital applied in the undertakings, and these vary in accordance with the model of undertaking and the investing company’s cost of capital. Transmission Concession revenue in 9M12 was R$ 1,295,023, 20.08% more than in 9M11 (R$ 1,078,507). The difference is mainly due to the increase in the Company’s total transmission assets, due to the acquisitions taking place in 2011, principally of Abengoa, acquired by the subsidiary Taesa. The portion of the transmission revenue added by Taesa, in proportion to our equity interest, in 9M12 was R$ 581,311, compared to R$ 455,515 in 9M11.

80 CEMIG Revenue from transactions in electricity on the CCEE Revenue from transactions in electricity on the CCE (Câmara de Comercialização de Energia Elétrica, or Electricity Trading Chamber) in 9M12 was R$ 351,219, an increase of 134.12% relative to the revenue of R$ 150,017 in 9M11. This is mainly due to a much higher spot market price for electricity – which increased from an average of R$ 24.96/MWH in 9M11 to an average of R$ 116.42/MWH in 9M12. Other operational revenues This category refers to charged services, supply of gas, sharing of infrastructure, the subsidy for low-income consumers, and the other services provided under the concession. It was 33.02% higher in 3Q12, at R$ 982,343, than in 3Q11 (R$ 738,481).This difference is mainly due to supply of gas 29.53% higher in 9M12 than in 9M11, and the new criteria set by Aneel for the subsidy for low-income consumers, through Resolution 472 of January 2012, which established the method for calculation of the monthly difference of revenue, and the amount of funds to be paid to the distributors to pay for the difference, in applying the Social Electricity Tariff. For more information please see Explanatory Note 22 to the Consolidated Interim Financial Statements. Sector / regulatory charges: deducted from operational revenue The total of the sector and regulatory charges applied to Cemig in 9M12 was R$ 5,682,841, 10.59% more than in 9M11 (R$ 5,138,451). The main variations in these deductions from revenue, between the two years, are as follows: The Fuel Consumption Account – CCC The CCC charges for Cemig in 9M12 was R$ 456,147, 13.23% less than in 9M11 (R$ 525,687). This charge is for the costs of operation of the thermal plants in the national grid and in the isolated systems. It is prorated between electricity concession holders, in proportion to the scale of the market each one serves, on a basis set by an Aneel Resolution. The reduction is mainly due to the reduction in the unit cost of the CCC, set by an Aneel Resolution. CDE – Energy Development Account The deduction from revenue for the CDE in 9M12 was R$ 454,609, 18.57% more than in 9M11 (R$ 383,398). The CDE account (Conta de Desenvolvimento Energético) was created to this helped increase competitiveness of Brazilian electricity generated from alternative sources. The amounts of the payments are set by an Aneel resolution.

81 81 CEMIG Global Reversion Reserve – RGR The deduction from revenue for the RGR in 9M12 was R$ 222,957, 56.53% more than in 9M11 (R$ 142,438). The RGR (Reserva Global de Reversão) is a charge on electricity concession holders to provide funds for reversions of concessions, compulsory acquisition, expansion and improvement of public electricity service. The annual RGR quota payable is set at 2.5% of capex, pro rata tempore, with an upper limit of 3.0% of the concession holder’s revenue from wholesale and retail sales (excluding any originating from Itaipu), use of the electricity grid, and charged services, less any ICMS tax embedded in revenue, where applicable. The other most significant charges are calculated as a percentage of sales revenue – hence their changes between periods are substantially proportional to the changes in revenue. Operational costs and expenses (excluding Financial revenue/expenses) Operational costs and expenses, excluding Financial revenue (expenses) in 9M12 were R$ 9,716,297, 19.41% more than in 9M11 (R$ 8,136,659). For more information please see Explanatory Note 23 to the Consolidated Interim Financial Statements. The following paragraphs outline the main variations in expenses: Electricity bought for resale Revenue from electricity bought for resale in 9M12 was R$4,111,593, 28.37% more than in 9M11 (R$ 3,202,886). The main factors in the difference are: . Cemig D’s financial exposure to the spot market was 119.88% higher, at R$ 528,890, in 9M12 than in 9M11 (R$ 240,534), reflecting a higher average of spot market prices (PLD), in all the sub-markets – which rose from R$ 24.96 per MWh in 9M11 to R$ 116.42 per MWh in 9M12. . A higher volume of electricity acquired in regulated market auctions by Cemig D, as a way of minimizing the risks of financial exposure to the spot market. This is a non-controllable cost: in the distribution activity, the difference between the amounts used as a reference for calculation of tariffs and the cost actually incurred is compensated for in the next tariff adjustment. Personnel Personnel expenses in 9M12 were R$ 972,818, 8.42% more than in 9M11 (R$ 897,304). The difference is primarily due to the salary increase of 8.20% given to employees under the Collective Salary Agreement of November 2011.

82 CEMIG Employees’ and managers’ profit shares The expense on employees’ and managers’ profit shares in 9M12 was R$ 177,494, compared to R$ 70,749 in 9M11, an increase of 150.88%. The considerable variation between the two periods arises from the fact that in 2012 profit shares agreed with the unions for the business year were recognized in the period, whereas in 2011 the greater part was provisioned only in the fourth quarter of the year, since the agreement was concluded in December of 2011. Outsourced services The expense on outsourced services in 9M12 was R$ 777,766, 7.83% more than in 9M11 (R$ 721,268). Most of the change is due to expenditure on consultancy contracted by the jointly-controlled subsidiary Taesa, and maintenance and conservation of electrical installations and equipment. A detailed breakdown of outsourced services is given in Explanatory Note 23b to the Consolidated Interim Financial Statements. Gas bought for resale The expense on gas bought for resale in 9M12 was R$ 356,028, 51.00% more than in 9M11 (R$ 235,785). This primarily reflects the increase in the volume purchased, reflecting higher sales of gas by Gasmig in 2012, in turn reflecting increased industrial activity, reflecting expansion of consumption by clients in the “Steel Valley” (Vale do Aço) and the South of Minas (Sul de Minas) region. Operational provisions Operational provisions in 9M12 were R$ 130,508, 37.01% less than in 9M11 (R$ 207,185). The main factors in this difference are: . Employment-law claims: Reversals of R$ 6,844 in 9M12, compared to new provisions of R$ 16,835 added in 9M11. . Third-party liability cases: Reassessment by the company of expectations of loss in its contingencies for civil actions, resulting in an additional provision of R$ 27,197 in the third quarter of 2011. . Environmental: Reassessment by the legal advisers, due to case law on the subject, of the probability of loss in an action disputing environmental compensation for protection and preservation of water tables at Cemig’s hydroelectric projects that are an operation, resulting in an additional provision of R$ 20,768 in third quarter 2012.

83 83 CEMIG . Regulatory: Reversal, in 2012, of provisions totaling R$ 7,945, on withdrawal of a notification by Aneel for claimed non-compliance with distribution outage indicators, that had been posted in the third quarter of 2011, in the amount of R$ 17,539 (part of this amount having already been rectified by the regulator in the fourth quarter of 2011). Other expenses, net The Other expenses, net account line in 9M12 was R$ 330,093, 39.96% higher than in 9M11 (R$ 235,852), mainly reflecting cultural sponsorships under the Rouanet (cultural sponsorship) law (which give rise to deductions for corporate income tax), and the increase in the PIS, Pasep and Cofins taxes on Other revenues. Financial revenue (expenses) The company posted net financial expenses of R$ 803,999 in 9M12, compared to net financial expenses of R$ 765,909 in 9M11. The main factors in this result are: . Revenue from late charges on overdue electricity bills in 9M12, at R$ 133,378, was 23.25% higher than in 9M11 (R$ 108,214). Among other factors, this reflects implementation of collection follow-up by e-mail and text messages, with more effort applied also to standard methods such as follow-up letters and formal demands. . Revenue from cash investments was 30.30% lower – on less cash invested in 2012. . Gains on foreign exchange variations: R$ 38,670 in 9M12, compared to R$ 8,211 in 9M11. This difference mainly reflects the results of cash investments in foreign currency by the jointly-controlled subsidiary Taesa. . Lower expense on costs of loans and financings: This total cost was R$ 962,942 in 9M12, compared to R$ 1,025,697 in 9M11. The lower figure basically results from the lower aggregate of the CDI (interbank CD) rate in 9M12 than in 9M11: 6.59% in 9M12, compared to 8.69% in 9M11. . Expense due to exchange rate variations: This was R$ 69,089 in 9M12, compared to R$ 18,674 in 9M11. The higher figure mainly reflects exchange rate variations on dollar-denominated loan contracts of the subsidiary Taesa arising from the acquisition of Abengoa. The breakdown of financial revenues and expenses is in Explanatory Note 24 to the Consolidated Interim Financial Statements.

86 CEMIG Profit for the quarter Cemig reports consolidated net profit for 3Q12 of R$ 937,131, which compares with R$ 657,247 in 3Q11, a year-on-year increase of 42.58%. An important element in the 3Q12 results is recognition of a gain of R$ 258,705, on issuance of shares arising from the Public Offering of Shares by Taesa (indirectly-held subsidiary of Cemig GT); and from capitalization, by subscription of new shares, of Renova, an indirect subsidiary of Light.

Revenue from supply of electricity to final consumers in 3Q11 was R$ 4,149,902, 8.60% higher than in 3Q11 (R$ 3,821,219). The main factors affecting revenue in 2012 were: . Tariff increase for Cemig D with average effect on consumer tariffs of 3.85%, effective April 8, 2012. . Tariff increase for Cemig D with average effect on consumer tariffs of 7.24%, starting from April 8, 2011. . Volume of energy invoiced to final consumers 3.84% higher (this excludes Cemig’s own internal consumption). . Contractual upward indexed adjustment to prices paid by Free Consumers, the main indexor being the IGP–M inflation index.

88 CEMIG Revenue from wholesale electricity sales Although the volume of electricity sold to other concession holders in 3Q12 was 5.19% lower than in 3Q11, revenue from these sales was 15.87% higher, at R$ 487,684 (vs. R$ 420,897 in 3Q11) due to the average sale price being 22.21% higher – at R$ 139.84/MWh, compared to R$ 114.42/MWh in 3Q11. Revenue from use of the electricity distribution systems (TUSD) The revenue from the TUSD (Tariff for Use of the Distribution System), received by Cemig D and Light, was 5.97% lower in 3Q12, at R$ 527,684, compared to R$ 561,195 in 3Q11. This revenue comes principally from charges to Free Consumers on the electricity sold by other agents of the electricity sector. Transmission concession revenue Transmission concession revenue in 3Q12 was R$ 548,798, 25.81% more than in 3Q11 (R$ 436,217). This variation mainly reflects the expansion of the Company’s transmission assets arising from the new acquisitions made in 2011 – principally of Abengoa, acquired through the indirect subsidiary Taesa. The transmission revenue aggregated by Taesa in 3Q12 (stated in proportion to Cemig’s stake) was R$ 318,502, compared to R$ 274,986 in 3Q11. Transactions in electricity on the CCEE Revenue from transactions in electricity on the CCEE (Electricity Trading Chamber) in 3Q12 was R$ 69,256, an increase of 37.13% relative to 3Q11 (R$ 50,504). This reflects the significantly higher average spot market price in 3Q12 – of R$ 131.14 – compared to R$ 20.61 in 3Q11. Other operational revenues This total includes charged services, supply of gas, sharing of infrastructure, the subsidy for the low-income consumer electricity tariff, and other services provided under the concession. It was 36.69% higher in 3Q12 (at R$ 344,744) than in 3Q11 (R$ 252,204). This difference is mainly due to supply of gas 35.61% higher in 3Q12 than in 3Q11, and the new criteria set by Aneel for the subsidy for low-income consumers, by its Resolution 472 of January 2012, which established the method for calculation of the monthly difference of revenue, and the amount of funds to be paid to the distributors to pay for the difference, in applying the Social Electricity Tariff.

The main variations in these deductions from revenue between the two years are as follows: Global Reversion Reserve – RGR The deduction from revenue for the RGR in 3Q12 was R$ 76,891, 51.53% higher than the figure for 3Q11 (R$ 50,742). The RGR (Reserva Global de Reversão) is a charge on electricity concession holders to provide funds for reversions of concessions, compulsory acquisition, expansion and improvement of public electricity service. The annual RGR payments are calculated as 2.5% of the concession holder’s capital expenditure, pro rata tempore per quarter, with a maximum of 3.0% of each concession holder’s total revenue from retail and wholesale supply (except supply originating from Itaipu), use of the electricity network, and charged services, less the related amounts of ICMS tax embedded in revenue, where applicable. The Fuel Consumption Account – CCC The deduction from revenue for the CCC in 3Q12 was R$ 114,256, 39.91% less than in 3Q11 (R$ 190,141). This charge is for the costs of operation of the thermal plants in the national grid and in the isolated systems. It is prorated between electricity concession holders, on a basis set by a Resolution issued by the regulator, Aneel. CDE – Energy Development Account The payments of the CDE are set by a resolution issued by the regulator, Aneel, and were 17.13% higher in 3Q12 than in 3Q11. The deduction from revenue for the CDE was R$ 151,978 in 3Q12, compared to R$ 129,751 in 3Q11.The other deductions from revenue are taxes, calculated as a percentage of amounts invoiced. Hence their variations are substantially proportional to the changes in revenue.

90 CEMIG Operational costs and expenses (excluding Financial revenue/expenses) Operational costs and expenses (excluding Financial revenue (expenses)) totaled R$ 3,545,251 in 3Q11, 26.83% more than in 3Q11 (R$ 2,795,209). This mainly reflects higher costs on employee profit shares, electricity bought for resale, operational reversions, charges for use of the national transmission grid, and gas bought for resale. The following paragraphs outline the main variations in expenses: Employees’ and managers’ profit shares The expense on employees’ and managers’ profit shares in 3Q12 was R$ 59,139, compared to R$ 46,659 in 3Q11, an increase of 26.75%. The considerable difference reflects recognition in 3Q12 of profit shares previously agreed with the unions for this business year; in 2011 the largest portion was provisioned only in the fourth quarter of the year – since in that year the negotiations were completed in December. Electricity bought for resale The expense on electricity bought for resale in 3Q12 was R$ 1,580,014 – 42.24% more than in 3Q11 (R$ 1,110,782). This primarily reflects: . Financial exposure of Cemig D to the spot market 114.34% higher – at R$ 208,634 in 3Q12, compared to R$ 97,339 in 3Q11, due to considerably higher average spot market prices in all the sub-markets – these averaged R$ 20.61/MWh in 3Q11, but R$ 131.14/MWh in 3Q12. . Electricity acquired by Cemig D by auction in the Regulated Market 24.67% higher, as part of a strategy to reduce risk of exposure to the spot market. . Expense on electricity from Itaipu 22.32% higher, at R$ 231,112 in 3Q12, vs., R$ 188,948 in 3Q11. This expense is indexed to the US dollar, and the increase reflects the dollar having appreciated against the Real in 3Q12, whereas it depreciated against the Real in 3Q11. The average value of the dollar applied to invoices in 3Q12 was R$ 2.038, 22.62% higher than the value of R$ 1.662 applied in 3Q11. Charges for use of the transmission grid The expense on charges for use of the transmission network was R$ 138,614 in 3Q12, 38.75% less than in 3Q11 (R$ 226,293). This expense is for the charges payable by electricity distribution and generation agents for use of the facilities that are components of the national grid. The amounts to be paid are set by an Aneel Resolution.

91 91 CEMIG Gas purchased for resale The cost of gas purchased for resale was R$ 138,150 in 3Q12, 48.62% more than in 3Q11 (R$ 92,954). This reflects the increase in the volume of gas purchased, to meet the requirements of higher sales of gas by Gasmig in 2012, due to increased industrial consumption following the expansion of Gasmig’s client base in the ‘Steel Valley’ (Vale do Aço) and South of Minas (Sul de Minas) regions.

The main factors in the difference between 3Q12 and 3Q11 are: . Revenue from late charges on overdue electricity bills in 3Q12, at R$ 49,019, was 61.59% higher than in 3Q11 (R$ 30,336). Among other factors, this reflects implementation of collection follow-up by e-mail and text messages, with more effort applied also to standard methods such as follow-up letters and formal demands. . Revenue from cash investments was 29.72% lower – on less cash invested in 2012. . Lower expense on costs of loans and financings: R$ 298,955 in 3Q12, compared to R$ 357,496 in 3Q11. This basically reflects a lower volume of loans linked to the CDI rate in 3Q12 than in 3Q11, and also the lower aggregate variation represented by the CDI rate in the quarter. In 3Q12 this variation was 1.91%, compared to 3.01% in 3Q11.

92 CEMIG . Expense on monetary updating of loans and financing 199.67% higher, at R$ 48,049, in 3Q12 than in 3Q11 (R$ 16,034). This reflects the higher value of the IGP–M inflation index in 3Q12 than in 3Q11, and also the effect of new capital raised as from the second quarter of 3Q11. . Expense of monetary updating on paid concessions: a total of R$ 17,086 in 3Q12, compared to R$ 4,135 in 3Q11. This reflects the significantly higher variation in the IGP–M inflation index in 3Q12 – which was 0.97% in 3Q11, but 3.78% in 3Q12. . Lower net expense from exchange rate variations on loans and financings in foreign currency, and on purchases of electricity from Itaipu, indexed to the dollar: R$ 1,893 in 3Q12, vs. R$ 23,182 in 3Q11. Appreciation of the dollar against the Real was significantly lower in 3Q12, at 0.46% – compared to 18.79% in 3Q11. Income tax and Social Contribution tax In 3Q12, Cemig’s expenses on income tax and the Social Contribution tax totaled R$ 346,145, on pre-tax profit of R$ 1,283,276, a percentage of 26.97%. In 3Q11 the expense on income tax and the Social Contribution tax was R$ 311,407, on pre-tax profit of R$ 968,654 – a percentage of 32.15%.

Principal responsibilities and attributions: As well as the attributions specified by Law 6404 of December 15, 1976, as amended, in relation to the Sarbanes-Oxley law – to which we are subject due to our shares being registered with the Securities and Exchange Commission (SEC), the capital markets regulator of the United states – we opted to exercise the exemption allowed by Rule 10-3A of the Exchange Act, regulated by SEC Release 82-1234, which accepts the activity of the Audit Board as an alternative to the Audit Committee as defined by the Sarbanes-Oxley law.

97 97 CEMIG Qualification and remuneration The Audit Board is a multi-disciplinary body, made up of members with various competencies (accounting, economics, business administration, and others). Their remuneration is 10% of the average earned by the Chief Officers. Résumé information on its members is on our website: http://ri.cemig.com.br. The Sarbanes-Oxley Law On July 23, 2007 Cemig obtained the first certification of its internal controls for mitigation of risks involved in the preparation and disclosure of the financial statements, issued in accordance with Section 404 of the Sarbanes-Oxley Law and the rules of the Public Company Accounting Oversight Board (PCAOB), which is included in the annual 20-F report relating to the business year ended December 31, 2006, filed with the US Securities and Exchange Commission (SEC). Management of corporate risks Corporate risk management is a management tool that is an integral part of our corporate governance practices. For it to have maximum efficacy, and for it to be more easily included in the organization’s culture, we aim to align it with the company’s process of Strategic Planning – which defines the strategic objectives of the company’s business. Other instances of management that relate to corporate risk management include: The Corporate Governance and Sustainability Committee; Compliance with the Sarbanes-Oxley Law; the Budget Prioritization Committee; Internal Auditing; the Energy Risks Management Committee; the Insurable Risks Committee; and the Control and Management Committee. Cemig’s corporate risks management structure was put in place in 2003. The risks matrix was revised for the first time in 2004, and a second time in 2005-6, aiming to identify changes in relation to the level of performance expected for each process. Effectiveness of the strategic controls has been improved, with a commitment to implement proposed mitigating action plans, consequently reducing the impact and probability of occurrence of innumerable risks. The method for measurement of risks that Cemig has chosen is the ORCA method, which was put in place with the assistance of external consultants, based on four dimensions: objectives; risks; internal controls; and alignment. To ensure safety and confidentiality of information, and speed in the process of periodic revision and review of the matrix of corporate risks, we use the SGIR (Integrated Risk Management System) application, which embodies the methodology referred to above. Cemig also has a site giving employees access to information on the subject, which enables the risks identified by managers to be continuously and dynamically monitored.

98 CEMIG Functional structure The main determining factor for the option adopted for functional structure is decentralized management by Risk Managers. This expresses the corporative and matricial nature of the function, with monitoring centralized by the Corporate Risk Management Unit, which generates relevant information with a systemic view and meets the demands of the Corporate Risk Management Committee. The Committee analyzes and prioritizes the actions established by the Board of Directors and the Executive Board. Challenges The main challenges to be faced by corporate risk management in Cemig are: . Improvement of the methodology of calculation of financial exposure risks, to provide the maximum possible objectivity for the assessment made by managers, offering senior management maximum security in the process of taking decisions. The results expected are: improvement in the quality of the information related to the matrix, and guarantee of compliance with the directive guidelines that arise from the Corporate Risk Management Policy. . Creation of standard reports, to meet the needs of various decision levels in the company. Statement of Ethical Principles and Code of Professional Conduct The Board of Directors’ approval, in May 2004, of the Statement of Ethical Principles and Code of Professional Conduct (http://ri.cemig.com.br), stating a list of 11 principles of ethical conduct and values incorporated into Cemig’s company culture, was an important step in perfecting Cemig’s internal system of corporate government and increasing its overall corporate transparency. Cemig’s Ethics Committee was created on August 12, 2004, to coordinate all actions relating to management of the Declaration of Ethical Principles and Code of Professional Conduct. This includes assessment of and decision on any possible noncompliances with the document. After the Ethics Channel was created in December 2006, to be used only by Cemig employees and workers, the Ethics Committee began to accept anonymous reports through the Anonymous Reporting Channel (Canal de Denúncia Anônima), available on the company’s Intranet. Items to be reported on this channel are any irregular practices contrary to the Company’s interests, including: financial fraud, including adulteration, falsification or suppression of financial, tax or accounting documents; misappropriation of goods or funds; receipt of undue advantages by managers or employees; irregular contracting; and other practices considered to be illegal.

99 99 CEMIG The Ethics Committee This was created on August 12, 2004, with three sitting members and three substitute members, and is responsible for management (interpretation, publicizing, application and updating) of the Code of Professional Conduct. This committee can receive and investigate any reports of violations of the ethical principles and rules of conduct, provided they are presented in a written document signed by the interested party, and sent to the address: Cemig, Av. Barbacena 1200, SA/17°/B2, accompanied by indication of means of proof (witnesses, documents or other sufficient/appropriate means). They can also be sent by email or telephone – the address and phone number are well known to all the company’s employees. In December 2006 we put in place our Anonymous Reporting Channel, available on the corporate intranet, the purpose of which is to receive, submit and process accusations of irregular practices, such as financial fraud, undue appropriation of assets, receipt of irregular advantages or illegal contracting. This channel is one more step for the company in the direction of improving transparency, correct behavior and the concept of corporate governance within Cemig. This new instrument of corporate governance improves the management of our employees and of our business, and reaffirms our ethical principles. Cemig’s Statement of Ethical Principles and Code of Professional Conduct is based on 11 Principles, which express the ethical conduct and values incorporated into its culture.

Management is responsible for the preparation of the individual interim financial information in accordance with CPC 21(R1) - Interim Financial Reporting and the consolidated interim financial information in accordance with CPC 21(R1) and IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), as well as for the presentation of such information in accordance with the standards issued by the Brazilian Securities and Exchange Commission (CVM). Our responsibility is to express a conclusion on this interim financial information based on our review. Scope of review We conducted our review in accordance with Brazilian and international standards on review of interim financial information (NBC TR 2410 and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the standards on auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we have not been engaged to issue an audit opinion. Due to the materiality of the matter described in the “Basis for disclaimer of conclusion”, below, we were unable to express a conclusion on our review.

© 2012 Deloitte Touche Tohmatsu. All rights reserved. Basis for disclaimer of conclusion As mentioned in Note 29, (a) on September 11, 2012, Provisional Act 579 (“MP 579” or “MP”) was enacted to regulate the extension of electric power generation, transmission and distribution concession services; (b) on September 14, 2012, Decree 7805 was enacted to regulate MP 579. Both MP 579 and Decree 7805 impact the Company’s operations. Under this legislation, the Company is allowed to extend the terms of its electric power generation and transmission concession agreements for one additional period, at the Concession Grantor’s discretion, for up to 30 years, provided that it agrees to accelerate the payment of its current agreements to December 2012, and meets other requirements set forth by the Concession Grantor, which include: (i) having its revenue set in conformity with the criteria; (ii) the service quality standards set forth by ANEEL have been complied with; and (iii) agreement as to the indemnity amounts defined for the concession assets. On October 15, 2012, subsidiary Cemig Geração e Transmissão S.A. expressed its preliminary intention favorable to the acceptance of the concession term relating to certain generation stations included in Agreement 007/97 and to the transmission assets included in Agreement 006/07, as mentioned in Note 29. On November 1, 2012, Interministerial Rules 578, 579 and 580 were issued, whereby Ministry of Mining and Energy provided the new rates applicable to electric power generation activities, the new Annual Permitted Revenue (RAP) amounts applicable to the electric power transmission activities performed by the subsidiary, effective January 1, 2013, in the amount of R$148 millions, as well as the amount of indemnities for transmission assets, in the amount of R$285 million. As at September 30, 2012, the Company had electric power transmission assets classified in current and noncurrent assets, under line item “Concession assets”, in the amount of R$723 million, and a RAP for the 2012/2013 cycle under Agreement 006/97 set at R$485 million, and account balances relating to electric power generation assets classified in noncurrent in line item Property, plant and equipment, for which the subsidiary expressed its preliminary intention favorable to the acceptance of extending the term of the concession agreement in the amount of R$763 million. For these generation businesses, the Concession Grantor did not consider that the Company has right to an indemnity. Additionally, for hydroelectric power plants Jaguara, São Simão and Miranda, whose concession term will expire in August 2013, January 2015 and December 2016, respectively, the Subsidiary´s management understands that it has the right to extend the concession terms under the conditions preceding to MP 579, in conformity with clauses established in concession agreements and in Article 19 of Law 974/1995. Accordingly, it did not express a favorable intention as to the acceptance of the extension. As at September 30, 2012, the Company has an account balance relating to hydroelectric power plants Jaguara, São Simão and Miranda, classified in noncurrent assets, in the amount of R$1,335 million. The Company´s management is analyzing, supported by studies and projections, the conditions established for extending the subsidiary´s concession term and the corresponding financial-economic effects, so as to be able to conclude on the ratification or not for the concession term extension, whose final response is due by December 4, 2012. As the Company´s management has not yet concluded its analysis on the intention or not to extend the concession and the accounting effects thereof, no adjustment has been recorded in the interim financial statements for the three- and nineperiods ended September 30, 2012. Consequently, there is significant uncertainty as to the realizable value of the assets and any measurement of the liabilities directly and indirectly linked to the concession agreements. Accordingly, we were unable to conclude on the accounting information included in these interim financial statements.

Disclaimer of conclusion on the interim financial information Due to the materiality of the matter described in the “Basis for disclaimer of conclusion”, we were unable to express a conclusion on our review of the interim individual and consolidated financial information of Companhia Energética de Minas Gerais - CEMIG. Consequently, we did not express a conclusion on the interim financial information referred to above. Emphases of Matter Without modifying our disclaimer of conclusion, we draw attention to Note 12 to the interim financial information, which mentions that the indirect jointly-controlled subsidiary Madeira Energia S.A. has recorded operating losses and that, as at September 30, 2012, current liabilities exceed current assets by R$1,943 million. The proportional impact on the Company is R$194 million. The management of Madeira Energia S.A. has plans to address the negative working capital situation. As at this date, Madeira Energia S.A. depends on the financial support from its shareholders and/or on borrowings from third parties to continue as a going concern. Without modifying our disclaimer of conclusion, we draw attention to Note 12 to the interim financial information, which mentions that the indirect jointly-controlled subsidiary Madeira Energia S.A. has incurred incorporation expenses related to the development of Santo Antônio hydroelectric power construction project. The property, plant and equipment relating to the aforementioned expenses totaled R$13,800 million as at September 30, 2012 which, according to financial projections prepared by Management, should be absorbed by means of the future revenues generated after the start-up of the entity’s activities. As at September 30, 2012, property, plant and equipment proportional to the Company’s interest in such indirect subsidiary is R$1,380 million. Other matters Interim statements of value added We have also reviewed the individual and consolidated interim statements of value added (“DVA”), for the nine-month period ended September 30, 2012, prepared under the responsibility of the Company’s management, the presentation of which is required by the standards issued by the Brazilian Securities and Exchange Commission (CVM) applicable to the preparation of Interim Financial Information (ITR) and considered as supplemental information for IFRS, which does not require the presentation of a DVA. Due to the materiality of the matter described in the “Basis for disclaimer of conclusion” paragraph, we were unable to express a conclusion on the interim statement of value added referred to above. Review of individual and consolidated interim financial information for the quarter ended September 30, 2011 and audit of the individual and consolidated financial statements for the year ended December 31, 2011 Except for the effects of the reclassifications presented in Note 2.2 to the interim financial statements, which were not reviewed by us or other auditors, the

All rights reserved. corresponding information and figures for the three- and nine-month periods ended September 30, 2011, presented for purposes of comparison, were previously audited by another auditor, who issued a report dated November 11, 2011, which contained emphasis-of-matter paragraphs regarding the fact that the indirect jointly-controlled subsidiary Madeira Energia S.A. and its subsidiary were incurring costs relating to the development of Santo Antônio hydroelectric power plant construction project, which, according to financial projections prepared by its Management, should be absorbed by future revenues from operating activities. The realization of the property, plant and equipment included in such costs, according to Management´s expectations, will occur from the start-up of operations. The information and amounts corresponding to the year ended December 31, 2011, presented for purposes of comparison, were previously audited by other independent auditors, and their report thereon, dated March 26, 2012, did not contain any emphasisof- matter paragraph regarding: (i) the fact that the indirect jointly controlled subsidiary Madeira Energia S.A. recognized recurring losses on its operations and recorded excess liabilities over current assets in the year ended December 31, 2011 in the consolidated amount of R$1,279 million. The proportional effect on the Company was R$128 million; and (ii) the fact that the indirect jointly controlled subsidiary Madeira Energia S.A. and its subsidiary were incurring costs on the development of Santo Antônio Hydroelectric Power Plant construction project which, according to financial projections prepared by its Management, should be absorbed by future revenues from operating activities.

COMPANHIA ENERGÉTICA DE MINAS GERAIS CEMIG LISTED COMPANY CNPJ 17155.730/0001-64 NIRE: 31300040127 MARKET ANNOUNCEMENT lans Cemig (Companhia Energética de Minas Gerais), a listed company with securities traded on the stock exchanges of São Paulo, New York and Madrid, hereby informs the public, the Brazilian Securities Commission (CVM), the São Paulo Stock, Commodities and Futures Exch in accordance with CVM Instruction 358 of January 3, 2002, as amended as follows: Referring to media reports published on December 19 in Valor Econômico, under the headline Cemig halts overhaul of power plants and December 20, 2012 in Diário do Comércio, under the Cemig halves its investment plan, Cemig provides the following complementary information: In 2010 Cemig structured a Program of Modernization and Overhaul of its 10 generating plants, for investment of R$ 1.6 billion by the year 2025. Execution of this program was begun with the works on the São Simão Hydroelectric Plant, for which the contract was signed in December 2011. That contract provides for disbursement of approximately R$ 46 million per year over a period of 100 months or a total investment of R$ 370.9 million. Also as part of this program, tender proceedings are currently in progress for start of the services on the Volta Grande and Salto Grande Hydroelectric Plants for planned investment of R$ 321 million and R$ 90 million, respectively. Based on the disbursement timetables for these two investments, the aggregate average annual investment is just under R$ 70 million/year. The legislation proposed in Provisional Measure 579, of September 11, 2012, and Decree 7805, of September 14, 2012, created a scenario of uncertainty in relation to renewal of the concessions for power plants that expire in or before 2017 and had been included in Power Plant Modernization and Overhaul Program: there is still not yet a decision by the regulatory agency on the manner and period for remuneration of the investments in overhaul and modernization to be carried out at these plants, in light of the new rules for concessions that expire in or before 2017.
