PRESENTATION OF FINANCIAL INFORMATION

Companhia Energética de Minas Gerais–CEMIG is a sociedade por ações, de economia mista (a state-controlled mixed capital company) organized under the laws of the Federative Republic of Brazil, or Brazil. References in this annual report to “CEMIG,” “we,” “us,” “our” and the “Company” are to Companhia Energética de Minas Gerais–CEMIG and its consolidated subsidiaries, except when the reference is specifically to Companhia Energética de Minas Gerais–CEMIG (parent company only) or the context otherwise requires. References to the “real,” “reais” or “R$” are to Brazilian reais (plural) and the Brazilian real (singular), the official currency of Brazil, and references to “U.S. dollars,” “dollars” or “US$” are to United States dollars.

We maintain our books and records in reais. We prepare our financial statements in accordance with accounting practices adopted in Brazil, and with International Financial Reporting Standards or “IFRS”, as issued by the International Accounting Standards Board (IASB). For purposes of this annual report we prepared the consolidated statements of financial position as of December 31, 2013 and 2012 and the related consolidated statements of income and comprehensive income, cash flows and changes in shareholders’ equity for the years ended December 31, 2013, 2012 and 2011, in reais in accordance with International Financial Reporting Standards or IFRS, as issued by the IASB. Deloitte Touche Tohmatsu Auditores Independentes has audited our consolidated financial statements as of and for the years ended December 31,2013 and  2012 and KPMG Auditores Independentes has audited our consolidated financial statements as of and for the year ended December 31, 2011, as stated in their respective reports appearing elsewhere herein.

We restated our consolidated financial statements as of and for the year ended December 31, 2012 and December 31, 2011 as a result of the adoption, on January 1, 2013, of IFRS 11 (Joint Arrangements) and IAS 19 (Employee Benefits), or IAS 19. IFRS 11, which replaced IAS 31, states that jointly-controlled enterprises (joint ventures) must be accounted by the equity method and, therefore, the proportional consolidation method will no longer be allowed. We retroactively applied IFRS 11 and IAS 19 to 2012 and 2011 for comparison purposes pursuant to IAS 8 (Accounting Policies, Changes in Accounting Estimates and Errors).  The adoption of these new pronouncements impacted several line items of our consolidated financial statements.  See note 2.5 to our consolidated financial statements for a description of these pronouncement and its impact on our consolidated financial statements.

This annual report contains translations of certain real amounts into U.S. dollars at specified rates solely for the convenience of the reader. Unless otherwise indicated, such U.S. dollar amounts have been translated from reais at an exchange rate of R$2.3608 to US$1.00, as certified for customs purposes by the U.S. Federal Reserve Board as of December 31, 2013. See “Item 3. Key Information–Exchange Rates” for additional information regarding exchange rates. We cannot guarantee that U.S. dollars can be converted into reais, or that reais can be converted into U.S. dollars, at the above rate or at any other rate.

Selected Consolidated Financial Data

The following tables present our selected consolidated financial and operating information in IFRS as of the dates and for each of the periods indicated. You should read the following information together with our consolidated financial statements, including the notes thereto, included in this annual report and the information set forth in “Item 5. Operating and Financial Review and Prospects” and “Presentation of Financial Information.”

The selected consolidated financial data as of December 31, 2013, 2012  and 2011 and for each of the years ended December 31, 2013,2012 and 2011, in IFRS, has been derived from our audited consolidated financial statements and the notes thereto included elsewhere in this annual report. U.S. dollar amounts in the table below are presented for your convenience. Unless otherwise indicated, these U.S. dollar amounts have been translated from reais at R$ 2.3608 per US$1.00, the exchange rate as of December 31,  2013. The real has historically experienced high volatility. We cannot guarantee that U.S. dollars can be converted into reais, or that reais can be converted into U.S. dollars, at the above rate or at any other rate. On April 18, 2014, the exchange rate for reais was R$2.2370 per US$1.00. See “—Exchange Rates.”

We restated our consolidated financial statements as of and for the year ended December 31, 2012 and December 31, 2011 as a result of the adoption, on January 1, 2013, of IFRS 11 (Joint Arrangements) and IAS 19 (Employee Benefits)..  We retroactively applied IFRS 11 and IAS 19 to 2012 and 2011 for comparison purposes pursuant to IAS 8 (Accounting Policies, Changes in Accounting Estimates and Errors).  The adoption of these new pronouncements impacted several line items of our consolidated financial statements.  See note 2.5 to our consolidated financial statements for a description of these pronouncement and its impact on our consolidated financial statements.

We have not restated data for 2010 and 2009 to reflect the application of IFRS 11 and IAS 19, as described in note 2.5 to our financial statements.  In particular, data for 2010 and 2009 reflect the results of our joint venture entities through proportional consolidation in , 2010 and 2009, as opposed to the equity method of accounting applicable in 2013, 2012, and 2011, and therefore data for 2009 and 2010 is not comparable to data for 2011, 2012 and 2013

Exchange Rates

On March 4, 2005, the National Monetary Council (Conselho Monetário Nacional), or CMN, consolidated the commercial rate exchange market and the floating rate market into a single exchange market. Such regulation allows, subject to certain procedures and specific regulatory provisions, the purchase and sale of foreign currency and the international transfer of reais by a foreign person or company, without limitation as to amount. Additionally, all foreign exchange transactions must be carried out by financial institutions authorized by the Brazilian Central Bank (Banco Central do Brasil), or the Central Bank, to operate in this market.

Brazilian law provides that whenever there (i) is a significant imbalance in Brazil’s balance of payments or (ii) are major reasons to foresee a significant imbalance in Brazil’s balance of payments, temporary restrictions may be imposed on remittances of foreign capital abroad.  In the past, the Central Bank has intervened occasionally to control unstable movements in foreign exchange rates. We cannot predict whether the Central Bank or the Federal Government will continue to let the real float freely or will intervene in the exchange rate market. The real may depreciate or appreciate against the U.S. dollar and other currencies substantially in the future, Exchange rate fluctuations may affect the U.S. dollar amounts received by the holders of Preferred ADSs or Common ADSs. We will make any distributions with respect to our preferred shares or common shares in reais and the depositary will convert these distributions into U.S. dollars for payment to the holders of Preferred ADSs and Common ADSs. We cannot asure you that such measures will not be taken by the Brazilian Government in the future, which could prevent us from making payments to the holders of our ADSs. Exchange rate fluctuations may also affect the U.S. dollar equivalent of the real price of the preferred shares or common shares on the Brazilian stock exchange where they are traded. Exchange rate fluctuations may also affect our results of operations.  For more information see “Risk Factors — Risks Relating to Brazil — Exchange rate instability may adversely affect our business, results of operations and financial condition and the market price of our shares, the Preferred ADSs and the Common ADSs”.

The table below sets forth, for the periods indicated the low, high, average and period-end exchange rates for reais, expressed in reais per US$1,00.

Risk factors

In evaluating an investment in our Company, the investor should take into consideration the following risks, as well as the other information in this annual report.

Risks relating to Cemig

Public authorities may intervene in concessions, in the interests of ensuring proper provision of services, and this could adversely affect the Company’s operational and financial results.

Public authorities may intervene in concessions to ensure appropriate provision of services, or faithful compliance with provisions of contracts, regulations or laws, and may also interfere in operations or revenues arising from operations of the facilities of the Company or its subsidiaries. In the event of intervention, the Company could be adversely affected.

We cannot be certain of the renewal of our concessions.

We carry out the majority of our power generation, transmission and distribution activities under concession contracts entered into with the Brazilian federal government. The Brazilian Constitution requires that all concessions relating to public services be awarded through a bidding process. In 1995, in an effort to implement these constitutional provisions, the federal government adopted certain laws and regulations, known collectively as the Concessions Law, governing bidding procedures in the power industry.

On September 11, 2012 the Brazilian government issued Provisional Measure 579 (‘PM 579’), later converted into Law No. 12,783, which governs extension of the concessions granted prior to Law No. 9074 of July 9, 1995. Under that law, as from September 12, 2012 these concessions can be extended only once, for up to 30 years, at the option of the concession-granting power. On December 4, 2012, the Company signed the second amendment to Transmission Concession Contract 006/1997, which extended the concession for 30 years under the terms of PM 579, from January 1, 2013. This resulted in an adjustment to the Permitted Annual Revenue (Receita Anual Permitida, or RAP), reducing the revenue that we will receive from those concessions.

The Brazilian government has compensated us for the reduction of the RAP of part of those concessions, but the assets in operation before the year of 2000 have not yet been compensated. According to Law Nº 12,783, we will be compensated for the reduction of the RAP of the assets in operation before 2000, in 30 years, adjusted for the Amplified National Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo, or IPCA).

The Company opted not to request extension of the generation concessions that expire within the period 2013 to 2017. For the plants that would have had a first extension before PM 579, which include the Jaguara, São Simão and Miranda plants, the Company believes that Generation Concession Contract 007/1997 allows for the extension of the concession of those plants for an additional 20 years, without application of any additional restriction.

Based on this understanding Cemig GT applied for an order of mandamus against an act of the Mining and Energy Minister with the objective of ensuring its right to extension of the period of the concession of the Jaguara Hydroelectric Plant, in the terms of Clause 4 of Concession Contract 007/1997, obeying the original bases of this contract, which were prior to Law Nº 12.783/2013. The Company was granted an interim injunction, which is still in effect, to continue commercial operation of the Jaguara hydroelectric plant until a judgment is given by the courts on the application for mandamus. The chance of a loss in this action has been classified as “possible”, due to its nature and the complexity involved in this particular case. The case has several particular elements characterizing the contingency: the singular nature of Concession Contract No. 007/1997, the unprecedented nature of the subject matter, and the fact that the action will be a leading case in consideration by the Brazilian Courts of the extension of concessions.

For the other generating plants with concessions that expire over the period from 2015 to 2017 — which include Três Marias, Salto Grande, Itutinga, Camargos, Piau, Gafanhoto, Peti, Tronqueiras, Joasal, Martins, Cajuru, Paciência, Marmelos, Sumidouro, Anil, Poquim, Dona Rita and Volta Grande — we have opted not to apply for extension under the terms of MP 579. As a result the generation business will not be affected negatively until the end of those concessions.

In light of the degree of discretion granted to the Federal Government, in relation to the new concession contracts, renewal of existing concessions, and, due to the new provisions established by PM 579 for renewal of distribution, generation and transmission concession contracts, we cannot guarantee that new concessions will be obtained or that our present concessions will be

8

Table of Contents

renewed on terms as favorable as those currently in effect. Non-renewal of any of our concessions could adversely affect our business, operational results and/or financial situation.

We might be unable to complete our proposed capital expenditure program.

Our by-laws state that we may use up to 40.0% of our annual EBITDA (earnings before interest, income taxes, depreciation and amortization), each fiscal year, on capital investments and acquisitions. Our ability to carry out our capital expenditure program is dependent upon a number of factors, including our ability to charge adequate rates for our services, our access to the domestic and international capital market and a variety of operational and other factors. In addition, our plans to expand our generation and transmission capacity are subject to the competitive bidding process governed by the Concessions Law. We cannot give any assurance that we will have the financial resources to complete this program, which could affect our business, operational results and/or financial situation.

Aneel has discretion to establish the rates Cemig Distribution charges consumers. These rates are determined by Aneel and designed to preserve the economic and financial balance of concession contracts entered into with Aneel (acting on behalf of the federal government).

Concession agreements and Brazilian law establish a price cap mechanism that permits three types of rate adjustments: (1) the Annual Adjustment; (2) the Periodic Review; and (3) the Extraordinary Review. The purpose of the Annual Adjustment (Reajuste Annual) is to compensate for changes in costs that are beyond the Company’s control, such as the cost of electricity for supply to consumers, the sector charges that are set by the federal government, and transport charges for use of the transmission and distribution facilities of other companies.

Manageable costs, on the other hand, are adjusted by the IGP—M inflation index, less an Efficiency Factor, known as the X Factor. Every five years there is a Periodic Tariff Review (Revisão Periódica Tarifária, or RTP), the purpose of which is to: identify the same variations in costs referred to above; remunerate the assets that the company has built in the period; decide on efficient operational costs, using a benchmarking method; and establish a factor based on the gains of scale, which will be taken into account in the subsequent annual tariff adjustments. An Extraordinary Tariff Review takes place whenever there is any unforeseen development significantly alters the economic-financial equilibrium of the concession. Therefore, the tariff review mechanism is subject to some extent to the discretionary power of Aneel, since it may omit to include investments that have been made, and could recognize operational costs as being lower than those actually incurred — which could result in a material adverse effect on our business, operational results and/or financial situation

Disruptions in the operation of, or deterioration of the quality of, services could have an adverse effect on the business, financial situation and operational results of the Company and its subsidiaries.

The operation of complex electricity transmission networks and systems involves various risks, such as operational difficulties and unexpected interruptions, caused by events that are beyond the control of the Company and its subsidiaries. These events include accidents, breakage or failure of equipment or processes, performance below expected levels of availability and efficiency of the transmission assets, and disasters such as explosions, fires, natural phenomena, landslides, sabotage or other similar events. Furthermore, actions by government agencies responsible for the electricity network, the environment, operations and other issues that affect electricity transmission could adversely affect the functioning and profitability of the operations of our transmission lines.

The Company’s insurance coverage may be insufficient to fully cover costs and/or losses that we may incur as a result of damage to our assets and/or service interruptions, which could result in a significant adverse effect on the business, financial situation and operational results of the Company and its subsidiaries. Further, the revenues that the Company and its subsidiaries generate from establishing, operating and maintaining its facilities are related to the availability of the services. Under the related concession contracts, the Company and its subsidiaries are subject to reduction of their Permitted Annual Revenue (Receita Anual Permitida, or RAP), and application of certain penalties, depending on the level of duration of unavailability of services. Therefore, interruptions in our transmission lines and substations may cause a material adverse effect on the Company’s business, financial situation and operational results.

We may incur losses in connection with pending litigation.

We are currently defending several legal and administrative proceedings relating to civil, administrative, environmental, tax, labor and other claims. These claims involve a wide range of issues and seek indemnities and reparation in money and by specific performance. Several individual disputes account for a significant part of the total amount of claims against the Company. The consolidated financial statements include contingency provisions in the total amount of R$ 306 million, as of December 31,

2013, for actions in which the chances of loss have been assessed as ‘probable’ (i.e. more likely than not). In the event that our provisions for legal actions are insufficient, payments for actions in excess of the amounts provisioned could adversely affect our operational results and financial situation.

Selling prices for electricity may be affected by the rules governing such sales, and by market conditions.

Under the applicable law, our generation companies are not allowed to sell energy directly to our distribution companies. As a result, our generation companies sell electricity in a regulated market through public auctions conducted by Aneel — this area of activity is referred to as the Regulated Market (or the Regulated Contracting Environment — Ambiente de Contratação Regulado, or ACR; or ‘the Pool’), or in the Free Market (Ambiente de Contratação, or ACL). The legislation allows distributors to contract with our generation companies in the Regulated Market and to reduce the volume of electricity contracted under existing supply contracts by up to 4% of the original contract amount, per year, for the entire contract period, exposing our generation companies to the risk of failing to sell their remaining energy at adequate prices.

We perform trading activities through power purchase and sale agreements, mainly in the Free Market (ACL), through our generation and trading companies. Contracts in the ACL may be entered into with other generating agents, energy traders, or mainly, with ‘Free Consumers’. Free Consumers are consumers with demand of 3MW or more: they are allowed to choose their electricity supplier. Some contracts with this type of consumer allow the consumer to buy a higher or lower volume of electricity from our companies than originally contracted (by 5% on average), and this could adversely affect our business, operational results and financial condition. Other contracts do not allow for this kind of flexibility in the purchase of electricity, however, increased competition in the Free Market could influence the occurrence of this type of arrangement in purchase contracts in the Free Market.

In addition to Free Consumers, there is a category of clients referred to as “Special Consumers”, which are those with contracted demand between 500kW and 3MW. Special Consumers are eligible to enter the Free Market provide they buy electricity from incentive-bearing alternative sources, such as Small Hydroelectric Plants, biomass plants or wind farms. We have conducted sales transactions for this type of electricity from certain electricity resources in certain companies of the group, but as from 2009 the sale of this type of incentive-bearing power supply has been increased, and the Company has formed a portfolio of purchase contracts that now occupies an important space in the Brazilian market for this type of electricity. Contracts for sale of electricity to this type of client have specific flexibilities to serve their needs, and these flexibilities of greater or lesser consumption are linked to the client’s history of energy consumption level. Market variations may generate short-term positions that could have an adverse financial effect on our results. The introduction of Law No. 12,783 brought certain changes to the organization of the Brazilian electricity market and the impacts of this new regulation cannot yet be assessed. Meanwhile there is the possibility that its results could have a less positive effect on our operations.

Low liquidity in the trading market, or volatility in future prices, due to market conditions and/or market perceptions, could negatively affect our operational results. Also, if we are unable to sell all the power that we have available — from our own generation capacity or from contracts under which we have bought supply of power — in the regulated public auctions or in the free market, the unsold capacity will be sold on the Electricity Trading Chamber (Câmara de Comercialização de Energia Elétrica, or CCEE) at ‘spot’ prices (Preços de Liquidação de Diferenças, or PLD), which tend to be very volatile. If this occurs in periods of low spot prices, our revenues and operational results could be adversely affected.

Requirements of, and restrictions by, the environmental agencies could result in our Company having additional costs.

Our operations related to generation, distribution and transmission of electricity, and distribution of natural gas, are subject to various federal, state and municipal laws and regulations, and also to numerous requirements relating to the protection of health and the environment. Delays by the environmental authorities, or refusal of license requests by them, and/or any inability on our part to meet the requirements set by these bodies during the environmental licensing process, may result in additional costs, or even, depending on the case, prohibit or restrict the construction or maintenance of these projects.

Non-compliance with environmental laws and regulations, such as building and operation of a potentially polluting facility without a valid environmental license or authorization, could, in addition to the obligation to redress any damages that may be caused, result in criminal, civil and/or administrative sanctions being applied. Under Brazilian legislation, criminal penalties such as restriction of rights, and even imprisonment, may be applied to individuals (including managers of legal entities), and penalties such as fines, restriction of rights or community service may be applied to legal entities. With respect to administrative sanctions, depending on the circumstances, the environmental authorities may: impose warnings, or fines, ranging from R$ 50 thousand to R$ 50 million; require partial or total suspension of activities; suspend or restrict tax benefits; cancel or suspend lines of credit from governmental financial institutions; or prohibit us from contracting with governmental agencies, companies or authorities. Any of these events could adversely affect our business, operational results and/or financial situation.

We are also subject to the Brazilian legislation that requires payment of compensation in the event that our activities have polluting effects. Under Federal Law No. 6,848/2009 and Minas Gerais State Decree No. 45,175/2009, up to 0.5% of the total amount invested in implementation of a project that causes significant environmental impact must be applied in compensatory measures, in an amount to be determined on a case by case basis by environmental authorities according to specific level of pollution and the environmental impact of the project.

State Decree No. 45,175 of 2009 also indicated that the compensation rate will be applied retrospectively to projects implemented prior to promulgation of the present legislation. That State Decree was altered by Decree No. 45,629/2011, which established that, for the reference value of the projects that cause significant environmental impact:

I –           for projects executed before the publication of Federal Law No. 9,985 of 2000, the net book value will be used, excluding revaluations or, in its absence, the value of the investment presented by the representative of the project; and

II –      compensation for environmental projects executed after the publication of Federal Law No. 9,985 will use the reference established in Item IV of Article 1 of Decree No. 45,175, calculated at the moment of execution of the project and updated based on an inflation-linked adjustment index.

In addition, the law of the State of Minas Gerais (location of the majority of Cemig’s operations) requires the constitution of a Legal Forest Reserve, corresponding to 20% of the total area of the rural property, used in our operations (State Law No. 14,309, of June 19, 2002, regulated by Decree No. 43,710, of January 8, 2004).

However, in 2012, the new Brazilian Forest Code was approved (Law No. 12,727, of October 17, 2012, converted from Provisional Measure 571, of 2012), which altered the Brazilian legislation on the subject, instituting, in its Article 12, §7º, the following:

“No Legal Reserve shall be required in relation to areas acquired or expropriated by the holder of a concession, permission or authorization for commercial operation of hydroelectric potential, where electricity generation enterprises or substations function or where electricity transmission or distribution lines are installed.”

However, since under Brazilian law the States may have their own specific legislation, we await a possible revision of the legislation of the State of Minas Gerais, in relation to what has been established in the new Forest Code, to enable us to make a correct evaluation of its impacts on the enterprises located in Minas Gerais.

Finally, the adoption or implementation of new safety, health and environmental laws, new interpretations of existing laws, increased rigidity in the application of the environmental laws, or other developments in the future might require us to make additional capital expenditure or incur additional operational expenses in order to maintain our current operations; or to curtail our production activities or take other actions that could have an adverse effect on our business, operational results or financial situation.

We are controlled by the Government of a Brazilian State, which may have interests that are different from those of investors.

As our controlling shareholder, the government of the Brazilian State of Minas Gerais exercises substantial influence on the strategic orientation of our business. The government of the State of Minas Gerais currently holds approximately 51% of our common shares and, consequently, has the right to the majority of votes in decisions of the General Meetings of our Shareholders, and can: (i) elect the majority of the members of our Board of Directors, and (ii) decide matters requiring approval by a specific majority of our shareholders, including transactions with related parties, shareholding reorganizations and the date and payment of any dividends.

In the past, the State Government has used, and may in the future use, its status as our controlling shareholder to decide whether we should engage in certain activities and make certain investments the intention of which might, principally, be to promote its political, economic or social objectives and not necessarily to achieve the objective of improving our business and/or operational results. Such actions could have a material adverse effect our business, operational results and/or financial situation.

Delays in the expansion of our facilities might significantly increase our costs.

We are currently engaged in the construction of additional hydroelectric and wind power plants, transmission lines and substations, and assessment of other potential expansion projects. Our ability to complete an expansion project on time, within a given budget and without adverse economic effects, is subject to a number of risks. For example:

11

Table of Contents

·             we may experience problems in the construction phase of an expansion project (e.g.: work stoppages, unforeseen geological conditions, environmental and political and environmental uncertainties, liquidity of partners or contractors);

·             we may face regulatory or legal challenges that delay the initial operation date of an expansion project;

·             our new facilities may possibly not operate at the designated capacity or its costs of operation may be greater than planned;

·             we may possibly not be able to obtain adequate working capital to finance our expansion projects; and

·             we may encounter environmental issues and claims by the local population during the construction of power plants, transmission lines or substations.

If we experience these or other problems relating to the expansion of our electricity generation or transmission capacity, we may be exposed to increased costs, or we may fail to achieve the revenues we planned in connection with such expansion projects.

Aneel, the electricity regulator, has some discretion in setting the Permitted Annual Revenue (‘RAP’) of our transmission companies; if any adjustments result in a reduction of the RAP, this could have a material adverse effect on our operational results and financial condition.

The Permitted Annual Revenue (Receita Annual Permitida, or RAP) that we receive through our transmission companies is determined by Aneel, on behalf of the federal government. The concession contracts provide for two mechanisms for adjustment of revenues: (i) annual tariff adjustments; and (ii) the Periodic Tariff Review (Revisão Tarifária Periódica, or RTP). The annual tariff adjustment of our transmission revenues takes place annually in June and is effective in July of the same year. The annual tariff adjustments take into account the permitted revenues of the projects that have come into operation and the revenue from the previous period is adjusted by the IPCA index. The periodic tariff review previously took place every four years, but Law No. 12,783 changed the tariff review period to five years. Our first periodic tariff review took place in July 2005 and the second in July 2009. During the periodic tariff review, the investments made by the concession holder in the period and the operational costs of the concession are analyzed by Aneel, taking into account only investment that it deems to be prudent, and operational costs that it assesses as having been efficient, using a benchmarking methodology developed by using an efficiency model based on comparison of data among the various transmission companies in Brazil. Therefore, the tariff review mechanism is subject to some extent to the discretionary power of Aneel, since it may omit to include investments that have been made, and could recognize operational costs as being lower than those actually incurred – which could result in a material adverse effect on our business, operational results and/or financial situation.

As mentioned above, we extended the concessions of certain of our transmission lines, under Law No. 12,783, which resulted in an adjustment to the RAP of those concessions, lowering the revenue we will receive from those concessions. The Brazilian government has compensated us for a reduction in the RAP of a portion of these concessions, but the assets in operation before 2000 have not yet been compensated. According to Law No. 12,783, we will receive compensation for the reduction in the RAP of the assets in operation before 2000 over a period of 30 years, adjusted by the IPCA inflation index.

Employment-related legal claims, strikes and/or work stoppages could have an adverse impact on our business.

Substantially all of our employees are covered by the Brazilian employment-law legislation applicable to private-sector employees. We have entered into collective bargaining agreements with the labor unions representing most of our employees.

We are currently defending a number of employment-law claims brought by our employees, the great majority of which relate to overtime and compensation for hazardous work. We are also subject to claims related to outsourcing of services, in which employees of our contractors and subcontractors have brought actions against us for payment of outstanding labor liabilities.

In 2008 and 2009 there was no significant labor union action.  In the negotiations to reach the Collective Work Agreement (Acordo Coletivo de Trabalho, or ACT), for 2010, some of our employees went on strike for 20 days. During the negotiations for the 2011 Collective Agreement, there were five, intermittent days of work stoppage by our employees. During the 2012 negotiations, there was one day of stoppage, in which around 12% of the employees took part. In 2013, there was a stoppage of 22 days in which 10% of the employees took part. In all of these events, our Operational Emergency Committee was activated and the strikes and stoppages did not affect the supply of electricity to our consumers.

We do not have insurance against losses incurred as a result of business interruptions caused by employment-related actions. In the event of a strike, we could face an immediate loss of revenue. Contractual disputes, strikes, complaints or other types

of conflict relating to our employees or to unions that represent them may cause an adverse effect on our business, operational results or financial situation, or on our ability to maintain normal levels of service.

We are subject to rules and limits applied to levels of public sector borrowing and to restrictions on the use of certain funds we raise, which could prevent us from obtaining financing.

As a state-controlled company, we are subject to rules and limits on the level of credit that may be contracted by the public sector, set by the National Monetary Council (Conselho Monetário Nacional, or CMN) and by the Brazilian Central Bank. These rules set certain parameters and conditions for financial institutions to be able to offer credit to companies of the public sector. Thus, if we do not fall within these conditions and parameters, we may have difficulty in obtaining financing from Brazilian financial institutions, which could create difficulties for the implementation of our investment plan. Brazilian legislation also rules that a state-controlled company, in general, may use proceeds from external transactions with commercial banks (debt, including bonds) only to refinance financial obligations. As a result of these regulations, our capacity to incur debt is limited, and this could negatively affect the implementation of our investment plan.

We are subject to extensive and uncertain governmental legislation and regulation and any changes to such legislation and regulation could have a materially adversely effect on our business, operational results and/or financial situation.

The Brazilian federal government has been implementing policies that have a far-reaching impact on the Brazilian energy sector and, in particular, the electricity industry. As part of the restructuring of the industry, Law No. 10,848 of March 15, 2004, known as the New Industry Model Law, introduced a new regulatory structure for the Brazilian electricity industry.

This regulatory structure has undergone several changes over recent years, the most recent being the changes included by Provisional Measure 579 (‘PM 579’)(which was converted into Law 12,783), which governs the extension of the concessions granted by Law No. 9,074 of July 7, 1995. Under this law, such concessions can, as from September 12, 2012, be extended only once, for up to 30 years, at the option of the concession-granting power.

There are contractual restrictions on our capacity to incur debt.

We are subject to certain restrictions on our capacity to incur debt due to covenants set forth in our loan agreements. In the event of non-compliance on our part with an obligation contained in our financing contract with the Brazilian Development Bank (Banco Nacional de Desenvolvimento Econômico e Social, or BNDES), we have an obligation to strengthen the guarantees of the financing, on pain of early maturity of the contract. In 2009, 2010, 2011 and 2012, we were at times in non-compliance with some of our obligations under our loan agreements, and, although we have been able to obtain waivers from our creditors in relation to such non-compliances, no guarantee can be given that we will be successful in obtaining any particular waiver in the future. The existence of limitations on our indebtedness could prevent us from entering into new agreements to finance our operations or to refinance our existing obligations, which could adversely affect our business, results of operations and financial situation.

We operate without insurance policies against natural disasters and third party liability.

Other than in connection with flying, we do not have third party liability insurance covering accidents, and we have not sought proposals for this type of insurance. It is the Company’s view that the risk of occurrence of an event leading to a claim on third party liability insurance is small. Specific studies have been made on the subject, which prove the extremely low probability of events of this nature. Hence Cemig has not sought a proposal for, and has not contracted, insurance cover against natural disasters, such as earthquakes or floods, that might affect our facilities.

The insurance contracted by the Company may be insufficient to pay compensation for possible damages.

The Company maintains insurance only for fire, risks involving our aircraft, and operational risks, such as damage to equipment, as well as those types of insurance cover that are required by law, such as transport insurance of goods belonging to legal entities.

We cannot guarantee that insurances contracted are sufficient to cover in full any liabilities that may arise in fact in the course of our business nor that these insurance policies will continue to be available in the future. The occurrence of claims in excess of the amount insured, or which are not covered by the insurance policies contracted, might generate significant and unexpected additional costs, which could have an adverse effect on our business, operational results and/or financial situation.

The level of default by our consumers could adversely affect our business, operational results and/or financial situation.

13

Table of Contents

As of December 31, 2013, our total past due receivables from final consumers were approximately R$ 893 million, corresponding to 6.10% of our net revenues for 2013, and our allowance for doubtful accounts was R$ 585 million. Approximately 12.46% of our total receivables were owed by entities of the public sector. We may be unable to recover debts from several municipalities and other defaulting consumers. If these debts unsettled, in whole or in part, we will experience an adverse impact on our business, operational results and financial situation. In addition, the amount of our consumers’ debts in arrears that exceeds our allowance for doubtful accounts could have an adverse effect on our business, operational results and/or financial situation.

We are strictly liable for any damages resulting from inadequate rendering of electricity services.

Under Brazilian law, we are strictly liable for direct and indirect damages resulting from the inadequate rendering of electricity transmission and distribution services. In addition, when damages are caused to final consumers as a result of outages or disturbances in the generation, transmission and distribution system, whenever these outages or disturbances are not attributed to an identifiable member of the National System Operator (Operador Nacional do Sistema, or ONS) or to the ONS itself, the liability for such damages is shared among generation, distribution and transmission companies. Until a party with final responsibility has been identified, the liability for such damages will be shared in the proportion of 35.7% to the distribution agents, 28.6% to the transmission agents and 35.7% to the generation agents. These proportions are established by the number of votes that each of these types of electricity concession holder receives in the general meetings of the ONS, and as such, they are subject to change in the future. Thus our business, operational results and/or financial situation might be adversely affected as a result of any such damages.

Aneel may penalize our subsidiaries for failing to comply with our concession agreements, and/or authorizations granted to us, which could result in fines, other penalties or, depending on the severity of the non-compliance, expropriation of the concession agreements or revocation of the authorizations.

We conduct our generation, transmission and distribution activities pursuant to concession agreements entered into with the federal government, through Aneel, and/or pursuant to authorizations granted to the companies of our portfolio, as the case may be. Aneel may impose penalties if we fail to comply with any provision of the concession agreements, including those relating to compliance with the established standards of quality. Depending on the severity of the non-compliance, these penalties could include:

·                 fines per breach of contract of up to 2.0% of the concession holder’s revenues in last year prior to the date of the breach;

·                 injunctions related to the construction of new facilities and equipment;

·                 restrictions on the operation of existing facilities and equipment;

·                 temporary suspension from participating in bidding processes for new concessions for a period of up to two years;

·                 intervention by Aneel in the management of the concession holder that it is in breach; and

·                 repeal of the concession.

In addition, the federal government has the power to repeal any one of our concessions or authorizations, prior to the end of the concession term, in the case of bankruptcy or dissolution, or through expropriation, for reasons related to the public interest.

Also, delays in the implementation and construction of new energy undertakings can trigger the imposition of regulatory penalties by Aneel, which, under Aneel’s Resolution No. 63 of May 12, 2004, can vary from warnings to the early termination of concessions or authorizations.

We cannot guarantee that Aneel will not impose penalties or even repeal our concessions or authorizations in the event of a breach of a concession contract or authorization. Any compensation we may receive upon rescission of the concession contract and/or withdrawal of an authorization may not be sufficient to compensate us for the full value of certain investments. If any concession contract is rescinded due to fault of ours, the effective amount of compensation could be reduced as a result of fines or other penalties. Rescission of our concession contracts, or imposition of penalties, could adversely affect the Company’s business, operational results and/or financial situation.

Our ability to distribute dividends is subject to limitations.

14

Table of Contents

Whether or not the investor receives dividends depends on whether our financial situation permits us to distribute dividends under Brazilian law, and whether our shareholders, on the recommendation of our Board of Directors, acting in their discretion, determine suspension, due to our financial situation, of distribution of dividends in excess of the amount of mandatory distribution required under our by-laws in the case of the preferred shares.

Because we are a holding company with no revenue-producing operations other than those of our operating subsidiaries, we will be able to distribute dividends to shareholders only if the Company receives dividends or other cash distributions from its operating subsidiaries. The dividends that our subsidiaries may distribute depend on our subsidiaries generating sufficient profit in any given fiscal year. Dividends can be paid out from the profit accrued in each fiscal year, or from accumulated profits from previous years, or from profit reserves. Dividends are calculated and paid in accordance with the Brazilian Corporate Law and the provisions of the by-laws of each of our regulated subsidiaries.

We will need funds in the short term to fund our current and expected acquisitions.

We will need funds in the short term to fund our current and future acquisitions and investments. However, we cannot guarantee that we will be able to raise such funds in a timely manner and in the amounts necessary or at competitive rates, or that we will otherwise have cash in hand to finance our investments and acquisitions. If we are unable to raise funds as planned, we may be unable to meet our acquisition commitments, and our investment program could suffer delays or significant changes, which could adversely affect our business, financial situation or future prospects.

Foreign shareholders may be unable to enforce judgments against our directors or officers.

All of our directors and officers named in this annual report reside in Brazil. Substantially all of our assets, as well as the assets of these persons, are located in Brazil. As a result, it may not be possible for foreign shareholders to effect service of process within the United States or other jurisdictions outside Brazil upon these persons, or to attach their assets, or to enforce against them or our Company in United States courts, or the courts of other jurisdictions outside Brazil, judgments predicated upon the civil liability provisions of the securities laws of the United States or the respective laws of such other jurisdictions.

Brazil’s supply of electricity depends heavily on hydroelectric plants, which in turn depend on climatic conditions to produce electricity.

As is widely known, hydroelectric generation is predominant in Brazil — constituting more than 70% of total installed capacity. The advantages of hydroelectric power have also been widely publicized: it is a renewable resource, and enables substantial expenditures on fuels in thermal generation plants to be avoided. At the same time the main difficulty in the use of this resource arises from the variability of the flows to the plants: There are substantial seasonal variations in monthly flows, and in the total of flows over the year, which depend fundamentally on the volume of rain that falls in each rainy season.

To deal with this difficulty the Brazilian system, as well as having a complementary thermal generation system — about 20% of its total capacity — has major accumulation reserves, able to transfer water from the rainy season to the dry season, and even from one year to the next.

The operation of the whole system is coordinated by the National System Operator (Operador Nacional do Sistema, or ONS). Its primary function is to achieve optimal operation of the resources available, minimizing operational cost, and the risks of shortage of electricity. In periods when the hydrological situation is adverse, a decision by the ONS may, for example, reduce generation by hydroelectric plants and increase thermal generation, which results in higher costs for the hydroelectric generators. Also, in the event of extreme shortages of electricity due to adverse hydrological situations, the system could undergo rationing, which could result in an increase in the company’s costs and reduction of its cash flow.

Increases in electricity purchase prices could cause imbalance in the Company’s cash flow.

The prices in electricity purchase contracts signed by electricity distribution concession holders such as the Company are linked to certain variables, such as, for example, hydrological conditions, which are not under those concession holders’ control. Although any increases are passed through to the electricity distribution concession holders at the time of their tariff adjustments, their existence can result in mismatches of cash flow, with an adverse impact on the Company’s business, operational results and/or financial situation. In 2013 this possibility was significantly reduced by action in support of the distribution companies taken by the federal government, in directing funds from the Energy Development Account (Conta de Desenvolvimento Energético, or CDE) to payment of a significant proportion of these expenses. For 2014, the subject is under discussion between companies and the government, which is aware of the risks and should provide some form of assistance — it is known, for example, that R$ 13 billion is reserved for this purpose in the Federal Budget.

Risks relating to Brazil

The federal government exercises significant influence on the Brazilian economy. Political and economic conditions can have a direct impact on our business.

The federal government frequently intervenes in the country’s economy and occasionally makes significant changes in monetary, fiscal and regulatory policy. Our business, operational results or financial situation may be adversely affected by changes in government policies, and also by:

·                 fluctuations in the exchange rate;

·                 inflation;

·                 instability of prices;

·                 changes in interest rates;

·                 fiscal policy;

·                 other political, diplomatic, social and economic developments which may affect Brazil or the international markets;

·                 control on capital flows; and/or

·                 limits on foreign trade.

Measures by the Brazilian government to maintain economic stability, and also speculation on any future acts of the Brazilian government, can generate uncertainties in the Brazilian economy, and increase the volatility of the domestic capital market, adversely affecting our business, operational results and/or financial situation. If the political and economic situations deteriorate, we may face increased costs.

The President of Brazil has considerable power to determine governmental policies and actions that relate to the Brazilian economy. Uncertainties in relation to any potential political crises can contribute to economic instability. This can increase the volatility of the Brazilian securities market and could have an adverse effect on the Brazilian economy and our business, operational results and/or financial situation. It is not possible to predict whether the present government or any successor governments will have an adverse effect on the Brazilian economy, and consequently on our business.

Inflation and certain governmental measures to curb inflation may contribute significantly to economic uncertainty in Brazil and could harm our business and the market value of our shares, the Preferred ADSs and the Common ADSs.

Brazil has in the past experienced extremely high rates of inflation. Inflation, and some of the federal government’s measures taken in an attempt to curb inflation, have had significant negative effects on the Brazilian economy. Since the introduction of the real in 1994, Brazil’s inflation rate has been substantially lower than in previous periods. As measured by the IPCA index, Brazilian annual inflation rates in 2011, 2012  and 2013 were 6.0%, 5.84% and 5.91%, respectively. No assurance can be given that inflation will remain at these levels.

Future measures taken by the federal government, including increases in interest rates, intervention in the foreign exchange market or actions intended to adjust the value of the real, might cause increases in inflation, and consequently, have adverse economic impacts on our business, operational results and/or financial situation. If Brazil experiences high inflation in the future, we might be unable to adjust the rates we charge our consumers to offset the effects of inflation on our cost structure.

Substantially all of our cash operating expenses are denominated in reais and tend to increase with Brazilian inflation. Inflationary pressures might also hinder our ability to access foreign financial markets or might lead to further government intervention in the economy, including the introduction of government policies that could harm our business, operational results and/or financial situation or adversely affect the market value of our shares and as a result, of our Preferred ADSs and Common ADSs.

Exchange rate instability could adversely affect our business, operational results and/or financial situation and the market prices of our shares, the Preferred ADSs and the Common ADSs.

The Brazilian currency has been devalued periodically in the last four decades. Throughout this period, the federal government has implemented various economic plans and utilized a number of exchange rate policies, including sudden devaluations, periodic mini-devaluations during which the frequency of adjustments has ranged from daily to monthly, floating exchange rate systems, exchange controls and dual exchange rate markets. Although the prolonged periods of depreciation of the Brazilian currency have usually correlated with the rate of inflation in Brazil, devaluation over shorter periods has resulted in significant fluctuations in the exchange rate between the Brazilian currency and the U.S. dollar, and currencies of other countries.

In 2013, the real depreciated 15.3% against the U.S. dollar. Considering the volatility the world economy is facing, no assurance can be given that the real will not continue to depreciate against the U.S. dollar. On December 31, 2013, the buy exchange rate for the U.S. dollar against the real was R$ 2.0476/US$. On that date approximately 4.88% of our total indebtedness under loans, financings and debentures was denominated in currencies other than the real (84.78% of those contracts being denominated in U.S. dollars). If the real depreciates against the U.S. dollar, our related financial expenses will increase and our operational results and financial situation could be adversely affected. We recorded a foreign exchange-related expense of R$ 16 million in 2012, and a foreign exchange-related loss of R$ 28 million in 2013.

We also have entered into certain power purchase agreements denominated in U.S. dollars. We cannot guarantee that derivative instruments and the proceeds from our dollar-denominated purchase agreements will be sufficient to avoid an adverse effect on our business, operational results and/or financial situation in the event of adverse exchange rate fluctuations.

Changes in economic and market conditions in other countries, especially Latin American and emerging market countries, may adversely affect our business, operational results and/or financial situation, as well as the market price of our shares, Preferred ADS and Common ADSs.

The market value of the securities of Brazilian companies is affected to varying degrees by economic and market conditions in other countries, including other Latin American countries and emerging market countries. Although the economic conditions of such countries may differ significantly from the economic conditions of Brazil, the reactions of investors to events in those countries may have an adverse effect on the market value of securities of Brazilian issuers. Crises in other emerging market countries might reduce investors’ interest in securities of Brazilian issuers, including our Company. This could make it more difficult for us to access the capital markets and finance our operations in the future on acceptable terms or at all. Due to the characteristics of the Brazilian power industry (which requires significant investments in operating assets) and due to our financing needs, if access to the capital and credit markets is limited, we could face difficulties in completing our investment plan and refinancing our obligations, and this could adversely affect our business, operational results and/or financial situation.

Political and economic instability in Brazil may affect us.

Periodically, allegations of unethical or illegal conduct have been made with respect to people in the Brazilian government, including legislators and/or party officials. The possibility exists that further allegations on unethical or illegal conduct might be made at any time in relation to persons of the Brazilian government, including legislators and/or party representatives. If these events lead to a materially adverse perception of Brazil among investors, the trading value of our shares, the Preferred ADSs and/or the Common ADSs could decline, and our ability to access international markets could be reduced. In addition, any political instability resulting from such events could cause us to re-assess our strategies if the Brazilian economy suffers as a result.

Risks relating to the preferred shares, common shares, Preferred ADSs and Common ADSs

The preferred shares and Preferred ADSs generally do not have voting rights, and the Common ADSs can only be voted by proxy by providing voting instructions to the depositary.

Under the Brazilian Corporate Law and our by-laws, holders of our preferred shares, and, consequently, holders of our ADSs representing preferred shares, are not entitled to vote at our shareholders’ meetings, except in very limited circumstances. Holders of our Preferred ADSs may also encounter difficulties in the exercise of certain rights, including limited voting rights.

Holders of the ADSs for our common shares do not have automatic entitlement to vote in our General Meetings of Stockholders, other than by power of attorney, by sending a voting instruction to the depository.  In some circumstances, where there is not enough time to send the form with voting instructions to the depository, or in the event of omission to send the voting instruction, the holders of ADSs for Cemig’s preferred and common shares may be unable to vote by means of instructions to the depository.

Exchange controls and restrictions on remittances from Brazil might adversely affect holders of Preferred and Common ADSs

The investor may be adversely affected by the imposition of restrictions on the remittance to foreign investors of the proceeds of their investments in Brazil and the conversion of reais into foreign currencies. Restrictions of this type would hinder or prevent the conversion of dividends, distributions or the proceeds from any sale of preferred shares or common shares from reais into U.S. dollars. We cannot guarantee that the federal government will not take restrictive measures in the future.

Changes in Brazilian tax laws may have an adverse impact on the taxes applicable to sale of our shares, Preferred ADSs or Common ADSs.

Law No. 10,833 of December 29, 2003 provides that the sale of assets located in Brazil by a non-resident to either a Brazilian resident or a non-resident is subject to taxation in Brazil, regardless of whether the sale occurs outside or within Brazil. This provision results in the imposition of income tax on the gains arising from a sale of our preferred shares or common shares by a non-resident of Brazil to another non-resident of Brazil. There is no clear guidance as to the application of Law No. 10,833 and, accordingly, we are unable to predict whether Brazilian courts may decide that it applies to sales of our Preferred ADSs and Common ADSs between non-residents of Brazil. However, in the event that the sale of assets is interpreted to include a sale of our Preferred ADSs and Common ADSs, this tax law would accordingly result in the imposition of withholding taxes on the disposal of our Preferred ADSs and Common ADSs by a non-resident of Brazil to another non-resident of Brazil.

Exchanging Preferred ADSs or Common ADSs for underlying shares may have adverse consequences.

The Brazilian custodian for the preferred shares and common shares must obtain an electronic certificate of foreign capital registration from the Brazilian Central Bank to remit U.S. dollars from Brazil to other countries for payments of dividends, any other cash distributions, or to remit the proceeds of a sale of shares. If the investor decides to exchange his Preferred ADSs or Common ADSs for the underlying shares, the investor will be able to continue to rely, for five business days from the date of the exchange, on the depositary bank’s electronic certificate of registration in order to receive any proceeds distributed in connection with the shares. Thereafter, the investor may perhaps not be able to obtain and remit U.S. dollars abroad upon sale of the shares, or distributions of proceeds relating to the shares, unless the investor obtains his own certificate of registration under CMN Resolution No. 2,689 of January 26, 2000, which entitles foreign investors to buy and sell on the Brazilian stock exchanges. If the investor does not obtain this certificate, he will be subject to less favorable tax treatment on gains with respect to the preferred or common shares. If the investor attempts to obtain his own certificate of registry, he may incur expenses or suffer significant delays in the application process. Obtaining a certificate of registry involves generating significant documentation, including completing and filing various electronic forms with the Brazilian Central Bank and the Brazilian Securities Commission (Comissão de Valores Mobiliários, or CVM). In order to complete this process, the investor will usually need to engage a consultant or attorney who has expertise in Central Bank and CVM regulations. Any delay in obtaining this certificate could adversely impact the investor’s ability to receive dividends or distributions paid by the preferred shares or common shares outside Brazil or to receive timely repatriation of the investor’s capital. If the investor decides to exchange his preferred or common shares back into Preferred ADSs or Common ADSs, respectively, once he has registered his investment in preferred shares or common shares, he may deposit his preferred or common shares with the custodian and rely on the depositary bank’s certificate of registration, subject to certain conditions. We cannot guarantee that the depositary bank’s certificate of registry or any certificate of foreign capital registration obtained by an investor may not be affected by future legislative or other regulatory changes, nor that additional Brazilian restrictions applicable to the investor, or to sale of the underlying preferred shares, or to repatriation of the proceeds from the sale, will not be imposed in the future.

The relative volatility and illiquidity of the Brazilian securities market may adversely affect our shareholders.

Investing in securities of Latin America, such as the preferred shares, common shares, Preferred ADSs or Common ADSs, involves a higher degree of risk than investing in securities of issuers from countries with more stable political and economic environments and such investments are generally considered speculative in nature.

The Brazilian securities market is substantially smaller, less liquid, more concentrated and more volatile than major securities markets in the United States. This may substantially limit the investor’s ability to sell the shares underlying his Preferred or Common ADSs for the desired price and within the desired period. The São Paulo Stock Exchange (BM&FBovespa S.A. — Bolsa de Valores, Mercadorias e Futuros, or BM&FBovespa), the only stock exchange in Brazil on which shares are traded, had market capitalization of approximately R$ 2.45 trillion on December 31, 2013, and average daily trading volume of approximately R$ 7.4 billion in the year 2013.

Shareholders may receive reduced dividend payments if our net profit does not reach certain levels.

Under our by-laws, we must pay our shareholders a mandatory annual dividend equal to at least 50% of our net profit for the preceding fiscal year, based on our financial statements prepared in accordance with IFRS, and also in accordance with the accounting practices adopted in Brazil, and holders of preferred shares have priority of payment. Our by-laws also require that the mandatory annual dividend we pay to holders of our preferred shares must be equal to at least the greater of (a) 10% of the par value of our shares, or (b) 3% of the value of the portion of stockholders’ equity represented by our shares, in the event that such amount is greater than 50% of our net profit. If in a given fiscal year we do not have net profit, or our net profit is insufficient, our management may recommend at the Annual Shareholders’ Meeting in respect of that year that the payment of the mandatory dividend should not be made. However, there is also a guarantee given by the government of Minas Gerais State, our controlling shareholder, that a minimum annual dividend of 6% will in any event be payable to all holders of common shares and preferred shares issued up to August 5, 2004 (other than public and governmental holders) in the event that mandatory distributions have not been made in a given fiscal year.

Holders of the Preferred and Common ADS, and holders of our shares, may have different shareholders’ rights than holders of shares in U.S. companies.

Our corporate governance, disclosure requirements and accounting practices are governed by our by-laws, by the Level 1 Differentiated Corporate Governance Practices Regulations (Regulamento de Práticas Diferenciadas de Governança Corporativa Nível 1) of the BM&FBovespa, by the Brazilian Corporate Law and by the rules issued by the CVM. These regulations may differ from the legal principles that would apply if our Company were incorporated in a jurisdiction in the United States, such as Delaware or New York, or in other jurisdictions outside Brazil. In addition, the rights of an ADS holder, which are derived from the rights of holders of our common or preferred shares, as the case may be, to have his interests protected in relation to decisions by our board of directors or our controlling shareholder, may be different under the Brazilian Corporate Law than under the rules of other jurisdictions. Rules against insider trading and self- dealing and other rules for the preservation of shareholder interests may also be different in Brazil than in the United States, potentially establishing a disadvantage for holders of the preferred shares, common shares, or Preferred or Common ADSs.

The sale of a significant number of our shares or the issuance of new shares may materially and adversely affect the market price of our shares, Preferred ADSs and Common ADSs.

Sales of a substantial number of shares, or the perception that such sales could take place, could adversely affect the prevailing market price of our shares, or of the Preferred or Common ADSs. As a consequence of the issuance of new shares or sales of shares by existing shareholders, the market price of our shares and, by extension, of the Preferred and/or Common ADSs, may decrease significantly.

The investor may be unable to exercise first refusal rights in relation to our securities.

The investor may be unable to exercise the first refusal rights relating to the shares underlying his Preferred or Common ADSs unless a registration statement under the United States Securities Act of 1933), as amended (‘the Securities Act’), is in effect in relation to those rights or the exemption from registration requirements of the Securities Act is applicable. We are not obliged to apply for a registration statement in relation to these first refusal rights for our shares, and we cannot guarantee that we will apply for any such registration statement. Unless we apply for the registration statement or unless an exemption from the registration applies, the investor may receive only the net proceeds from the sale of his first refusal rights, made by the depositary; and if the first refusal rights cannot be sold, they may lapse.

Item 4.                     Information on the Company

Organization and Historical Background

We were organized in Minas Gerais, Brazil on May 22, 1952 as a sociedade por ações de economia mista (a state-controlled mixed capital company) with indefinite duration, pursuant to Minas Gerais State Law No. 828 of December 14, 1951 and its implementing regulation, Minas Gerais State Decree 3,710 of February 20, 1952. Our full legal name is Companhia Energética de Minas Gerais–CEMIG, but we are also known as CEMIG. Our headquarters are located at Avenida Barbacena, 1200, Belo Horizonte, Minas Gerais, Brazil. Our main telephone number is (55-31) 3506-3711.

In order to comply with legal and regulatory provisions pursuant to which we were required to unbundle our vertically integrated businesses, in 2004 we incorporated two wholly-owned subsidiaries of CEMIG: Cemig Geração e Transmissão S.A., referred to as Cemig Generation and Transmission, and Cemig Distribuição S,A,, referred to as Cemig Distribution, Cemig Generation and Transmission and Cemig Distribution were created to carry out the activities of electricity generation and transmission, and distribution, respectively.

Cemig was a factor in the decisions by several important companies to locate in Minas Gerais — such as Mannesmann, a steel company producing seamless tubes, due to the guarantee given by the state government that Cemig would be able to meet its demand for electricity (at that time, equal to half of the entire consumption of the state of Minas Gerais).

The first three hydroelectric plants built by Cemig were inaugurated in the 1950s: Tronqueiras, Itutinga and Salto Grande.

Starting in 1960, Cemig began its operations of electricity transmission and distribution. In the same period the Canambra consortium was formed, by a group of Canadian, American and Brazilian technical experts, who between 1963 and 1966 identified and evaluated the hydroelectric potential of the State of Minas Gerais. This study – at that time – was already aligned with the concept of sustainable development — it revolutionized the focus of construction of power plants in Brazil, as well as defining which projects would be able to be developed to supply future electric power needs.

In the 1970s Cemig took over responsibility for the distribution of electricity in the region of the city of Belo Horizonte, absorbing Companhia Força e Luz de Minas Gerais, and embarked on construction of more major power plants. In 1978 Cemig started operation of the São Simão hydroelectric plant, at that time its largest yet. This decade saw major progress in transmission: 6,000km of distribution lines in the state of Minas Gerais.

The Minas-Luz Program, a partnership between Cemig, Eletrobrás (Centrais Elétricas Brasileiras S.A.) and the Brazilian federal government, was created to expand service to low-income populations in the countryside and outer urban suburbs, including the shantytowns. The Emborcação hydroelectric plant, on the Paranaíba River, started operation in 1982 — at the time it was the Company’s second largest power plant, and with the São Simão plant it tripled the Company’s generation capacity. It was in 1983 that Cemig created its Ecological Program Coordination Management Unit — responsible for planning and development of a specific policy for environmental protection — enabling research into alternative energy sources, such as wind power and solar generation, biomass and natural gas, to become the subject of the Company’s research projects.

The subsidiary Gasmig (Companhia de Gás de Minas Gerais), was created in 1986, to distribute natural gas. On September 18 of that year the company changed its name from Cemig — Centrais Elétricas de Minas Gerais to Companhia Energética de Minas Gerais – Cemig. The change reflected the expansion of its area of operation to include multiple sources of electricity. By the end of the 1980s, Cemig was distributing electricity to 96% of the State of Minas Gerais according to Aneel (Agência Nacional de Energia Elétrica), the Brazilian electricity regulator.

In the 1990s, even during the period of economic crisis, Cemig, according to its records, served approximately 5 million consumers. In one year of the decade, it added 237,000 new connections of consumer units to electricity supply — a record in its history. Also in the 1990s, Cemig began to build hydroelectric plants in partnership with the private sector. It was by this method, for example, that the Igarapava hydroelectric plant, in the ‘Minas Triangle’ region, was built — starting operation in 1998.

In 2000, Cemig was included for the first time in the Dow Jones Sustainability Index — a recognition which it has repeatedly received in recent years. Cemig sees this as confirmation of its dedication to the balance between three pillars of corporate sustainability: economic, social and financial. The year 2000 was also marked by the simultaneous construction of three hydroelectric plants — Porto Estrela, Queimado and Funil — and by the number of Cemig’s consumers growing to more than 5 million for the first time in its history.

In 2001, Cemig began construction on 12 hydroelectric plants, and intensified its investments in the distribution and transmission systems. In the same year, Cemig’s shares were traded for the first time on the New York Stock Exchange.

In 2002, according to its records, The number of Cemig’s consumers exceeded 6 million for the first time — and it began construction on the Irapé hydroelectric plant, in the Valley of the Jequitinhonha river. In that year, also, trading began in Cemig’s shares on the Latibex segment of the stock exchange of Madrid.

In 2003, Cemig began simultaneous construction of several hydroelectric plants, as part of the effort to prevent rationing of electricity, and established several centers of excellence and research — focusing on climatology, thermoelectric generation, electricity efficiency and renewable electricity sources.

The year 2004 presented the Company with some major challenges: It was in 2004 that the structure of the new Brazilian regulatory framework came into force — the principal requirement being ‘unbundling’ is of its activities of distribution, generation and transmission. In 2005, as a consequence of this ‘unbundling’, Cemig operated as a holding company, with two wholly-owned subsidiaries:  Cemig Distribuição S.A. and Cemig Geração e Transmissão S.A.

In 2006 Cemig connected a further 230,000 new consumers in the state of Minas Gerais, and its investment in environmental preservation totaled R$ 60 million. The Irapé hydroelectric plant was inaugurated in July of 2006, and in that year the Company began to operate in other states, with the acquisition of a significant interest  in Light S.A. (“Light”), operating in the state of Rio de Janeiro, and Transmissoras Brasileiras de Energia — TBE, operating transmission lines in the North and South of Brazil.  Also, a consortium in which Cemig is a leading member began construction of a transmission line in a neighboring country, Chile.

In 2008, the Company acquired a stockholding in wind farms in the northern Brazilian state of Ceará, with potential for total generating capacity of approximately 100MW. It also participated in the consortium building the Santo Antônio hydroelectric plant, on the Madeira river.

In April 2009, Cemig acquired Terna Participações S.A., now called Transmissora Aliança de Energia Elétrica S.A. — Taesa.  And in the same year it increased its holdings in the electricity transmission sector with the acquisition of equity interests in the following companies:

Empresa Amazonense de Transmissão de Energia S.A. – EATE,

Empresa Paraense de Transmissão de Energia S.A. - ETEP,

Empresa Norte de Transmissão de Energia S.A. – ENTE,

Empresa Regional de Transmissão de Energia S.A. – ERTE and

Empresa Catarinense de Transmissão de Energia S.A. – ECTE.

This increased Cemig’s market share in Brazilian electricity transmission from 5.4% to 12.6%, making it the third largest transmission company in Brazil by Permitted Annual Revenue (RAP), according to Aneel figures.

2009 was the tenth year in which Cemig was included in the worldwide Dow Jones Sustainability Index — and in that year it was elected the world leader in sustainability among utilities. It continues to be the only company in the electricity sector of Latin America that has been included in the ‘DJSI World’ since the creation of that index.

In 2010 Cemig formed a partnership with Light for development of smart grid technology — with a view to increasing operational efficiency, and reducing commercial losses. Also in 2010 — for the second year running — Cemig was rated Prime (B—) by Oekom Research, a German agency that issues sustainability ratings.  In the same year Cemig GT (generation and transmission) signed a contract with Light for acquisition of 49% of the share capital of Lightger S.A., a special-purpose company holding the authorization for commercial operation of the Paracambi Small Hydro Plant.

In 2011 the Company acquired significant assets in generation and transmission, including:

(i)            50% of União de Transmissora de Energia Elétrica S.A. — Unisa (“Unisa”), owner of four transmission assets, from Abengoa Concessões Brasil Holding S.A. (“Abengoa”);

(ii)           an interest of 9.77% in the Belo Monte Hydroelectric Plant;

(iii)          stockholding control of Renova Energia S.A., which has operated for 11 years in small hydroelectric plants and wind farms; and

(iv)          interests in four small hydro plants in Minas Gerais.

In 2012, Taesa completed an agreement with Abengoa for acquisition of the remaining 50% of the share capital of Unisa. In the same year Cemig concluded consolidation of its investments in the transmission sector, by transfer of assets of this sector to Taesa.

It has created the largest wind farm complex in Brazil, located in the semi-arid region of the Brazilian state of Bahia, and sold a total of 690MW of installed electricity generation capacity in the reserve energy auctions of 2009 and 2010, the A—3 auction of 2011 and the A-5 auction of 2012.

On August 19, 2011 Light, through its subsidiary Light Energia, subscribed 50,561,797 of Renova’s common shares. As a result, Light Energia holds 34.85% of Renova’s common shares and 25.8% of its total capital. The transaction included a private placement of Renova’s shares in the approximate amount of R$ 360,0 million. Renova’s minority shareholders participated in the private placement, resulting in a total capital injection of R$ 376,0 million.

The common shares subscribed by Light Energia are part of the controlling stockholding block of Renova, and are half of the shares comprising that block, with the same rights and preferences attributed to the other common shares issued by Renova. To make the transaction possible, RR Participações S.A. (“RR”) and certain stockholders of Renova waived their right of first refusal in favor of Light Energia. Light Energia and RR entered into a stockholders’ agreement which regulated the exercise of the right to vote, purchase and sale of shares issued by Renova held by the parties, and their rights and obligations as stockholders of the Renova. Light has experience in building and operating generation projects, and in the sale and placement of electricity. We believe that this combination will enable Renova to position itself as one of the largest players in wind generation in Latin America, with unique and extremely attractive characteristics. The agreement also  contained a commitment by Light to buy 400MW of installed power capacity provided by Renova’s wind projects. The companies furtherhad the right of first refusal in the purchase or sale, as applicable, of wind energy in the long term. The principal purpose of this acquisition  was to accelerate the growth of Renova through a combination of its own technical capacity and pioneering experience in development of new projects and business, with our own experience, and contracts entered into in the Free Market.

On June 22, 2012, a Contract for Subscription of Units in Renova was signed by BNDES Participações S.A. (“BNDESPar”), Renova, Light, Light Energia and RR, regulating an investment in Renova by BNDESPar (the investment holding company of the Brazilian Development Bank (BNDES). The contract provided for a capital increase in Renova, to be decided at a later date, in the total amount of up to R$ 314,700,407.85, at a price of R$ 9.3334 per share.

Under the Contract for Subscription of Units, RR, Light Energia and InfraBrasil Fundo de Investimento em Participações assigned  their respective first refusal rights in the capital increase to BNDESPar. Also under the contract BNDESPar undertook to subscribe units in the capital increase in a minimum amount of R$ 250,000,009.70, and further to this minimum subscription, BNDESPar would share on a prorated basis in subscription of:

(i)             any unsubscribed Units, after the period for exercise of the first refusal right of the other stockholders of Renova; and

(ii)            any units not subscribed by the other stockholders of Renova that are sold in an auction to be held on the São Paulo Stock Exchange (BM&FBovespa) at the Price per Share (‘the Underwriting’).

As part of the investment agreement, RR, Light Energia and BNDESPar undertook to enter into a stockholders’ agreement to give BNDESPar the following rights:

(i)             election of 1 (one) member of the Board of Directors of Renova;

(ii)            right of joint sale in the event of direct or indirect disposal of the shares in Renova held by RR or Light Energia; and

(iii)           the right to subscribe secondary public offerings in Renova.

The investment agreement did  not result in sale of control by the controlling stockholders of Renova (RR and Light Energia), for the purposes of Article 254-A of the Brazilian Corporate Law, nor acquisition of control of Renova by BNDESPar, under Article 256 of that law.

BNDESPar’s entry into Renova gave it greater negotiating and financing capacity for making the investments that it had planned up to that date. As a result of this transaction, on December 31, 2012, Light’s holding in Renova was 21.99%.
