The credits for Pasep and Cofins taxes arise from payments made in excess by the Company as a result of adoption of the non-cumulative regime for revenues of the transmission companies whose electricity supply contracts were prior to October 31, 2003, and for which subsequent regulation by the Brazilian tax authority allowed review and inclusion in the cumulative regime. As a consequence of this review, restitution of excess tax paid in prior periods was allowed.

The balances of income tax and Social Contribution tax refer to tax credits in corporate income tax returns of previous years, and advance payments made in 2011, which will be offset against federal taxes payable, calculated during the business year, posted in Taxes and contributions.

Table of Contents

The credits of ICMS tax recoverable, posted in Non-current assets, arise from acquisitions of fixed assets, and can be offset in 48 months. The transfer to Current assets was made in accordance with Management’s estimates of the amounts likely to be realized up to the end of March 2012.

At its meeting on March 28, 2011, the Board of Directors approved the technical study prepared by Cemig’s Chief Finance and Investor Relations Officers’ Department on the forecasts for future profitability adjusted to present value, which show capacity for realization of the deferred tax asset in a maximum period of 10 years, as defined in CVM Instruction 371.

Table of Contents

In accordance with the individual estimates of Cemig, its subsidiaries, and its jointly-controlled subsidiaries, future taxable profits enable the deferred tax asset existing on March 31, 2011 to be realized according to the following estimate:

	Consolidated	Holding company
	IFRS	BRGAAP

2011	472,113	60,027
2012	296,239	49,220

2019 and 2020	95,984	60,901
	1,804,924	348,335

On March 31, 2011 the Holding Company has tax credits not recognized in its financial statements in the amount of R$100,839 (R$100,839 on December 31, 2010), which relate, basically, to the effective loss, due to the assignment of the credits in Accounts Receivable from the Government of the State to the Credit Rights Fund, in the first quarter of 2006, as per Explanatory Note 10. As a result of this assignment the provision for losses on recovery of the amounts constituted in previous years became deductible for the purposes of income tax and Social Contribution.

Deductible temporary differences and accumulated tax losses do not expire, under the tax legislation currently in force. Deferred tax assets have not been recognized in relation to these items, because it is not probable that future taxable profits will be available for the Company to be able to use the benefits of these.

b) Reconciliation of the expense on income tax and the Social Contribution tax:

This table shows the reconciliation of the nominal expense on income tax (rate 25%) and Social Contribution tax (rate 9%) with the actual expense, shown in the Income statement:

10. ACCOUNTS RECEIVABLE FROM THE GOVERNMENT OF THE STATE OF MINAS GERAIS AND CREDIT RECEIVABLES INVESTMENT FUND

The outstanding credit balance receivable on the CRC (Results Compensation) Account was transferred to the State of Minas Gerais in 1995, under an Agreement to assign that account (“the CRC Agreement”), in accordance with Law 8724/93, for monthly amortization over 17 years starting on June 1, 1998, with annual interest of 6% plus monetary updating by the Ufir index.

a) Fourth Amendment to the CRC Agreement

As a result of default in receipt of the credits specified in the Second and Third Amendments, the Fourth Amendment was signed, with the aim of making possible full receipt of the CRC balance through retention of dividends becoming payable to State Government. This agreement was approved by the Extraordinary General Meeting of Stockholders completed on January 12, 2006.

The Fourth Amendment to the CRC contract had backdated effect on the outstanding balance existing on December 31, 2004, and consolidated the amounts receivable under the Second and Third Amendments, corresponding to R$5,200,478 on March 31, 2011 (R$5,070,376 on December 31, 2010).

Table of Contents

The government of the state will amortize the debit in 61 consecutive half-yearly installments, becoming due by June 30 and December 31 of each year, over the period from June 2005 to June 2035 inclusive. The amounts of the portions for amortization of the principal, updated by the IGP-DI index, increase over the period, from R$28,828 for the 1st, to R$102,733 for the 61st – expressed in currency of March 31, 2011.

The debt is being amortized, as priority, by retention of 65% of the minimum obligatory dividends payable to the State Government. If the amount is not enough to amortize the portion becoming due, the retention may be of up to 65% of all and any amount of extraordinary dividends or extraordinary Interest on Equity. The dividends retained are to be used for amortization of the agreement in the following order: (i) settlement of past due installments; (ii) settlement of an installment for the current half-year; (iii) anticipated settlement of up to 2 installments; and, (iv) amortization of the debtor balance.

On March 31, 2011 the installments of the contract becoming due on June 30 and December 31, 2011 had already been amortized.

The Fourth Amendment to the agreement provides that, so as to ensure complete receipt of the credits, the provisions of the Bylaws must be obeyed — they define certain targets to be met annually in conformity with the Strategic Plan, as follows:

Target		Index required
Debt / Ebitda		Less than 2 (1)
(Debt) / (Debt plus Stockholders’ equity)		40% or less (2)
Capital expenditure and acquisition of assets		40%, or less, of Ebitda

Ebitda = Earnings before interest, taxes on profit, depreciation and amortization.

(1) Less than 2.5 in certain situations specified in the Bylaws.

(2) 50% or less, in certain situations also specified in the Bylaws.

b) Transfer of the CRC credits to a Receivables Investment Fund (“FIDC”)

On January 27, 2006 Cemig transferred the CRC credits into a Receivables Investment Fund (“FIDC”). The amount of the FIDC was established by the administrator based on long-term financial projections for Cemig, with estimation of the dividends that will be retained for amortization of the outstanding debtor balance on the CRC Agreement. Based on these projections, the FIDC was valued at a total of R$1,659,125, of which R$900,000 in senior units and R$759,125 in subordinated units.

The senior units were subscribed and acquired by financial institutions and will be amortized in 20 half-yearly installments, from June 2006, updated by the variation of the CDI plus interest of 1.7% of interest per year, guaranteed by Cemig.

The subordinated units were subscribed by Cemig and correspond to the difference between the total value of the FIDC and the value of the senior units.

Table of Contents

The updating of the subordinated units corresponds to the difference between the valuation of the FIDC using a rate of 10.00% per year, and the increase in value of the senior units by the variation of the CDI plus interest of 1.70% per year.

The composition of the FIDC is as follows:

	3/31/2011	12/31/2010
- Senior units held by third parties	830,923	890,517

- Subordinated units owned by Cemig	953,452	938,704
Dividends retained by the Fund	7,618	7,867
	961,070	946,571

Total	1,791,993	1,837,088

Movement in the FIDC in 1Q11 was as follows:

	Consolidated
	and Holding
	company

Balance at December 31, 2010	1,837,088
Monetary updating of the senior units	7,804
Monetary updating of the subordinated units	14,500
Amortization of the senior units	(67,399	)
Balance at March 31, 2011	1,791,993

Cemig paid dividends on December 21, 2010, R$67,399 being used for amortization of part of the senior units. Additionally, the Company injected R$18,835 into the fund to complete the amount necessary for redemption of the senior units and other operational expenses of the FIDC.

Table of Contents

c) Criterion of consolidation for the FIDC

Due to the guarantee offered by Cemig of settlement of the senior units, in the event that the dividends due to the state government are not sufficient for amortization of the installments, the consolidated Quarterly Information presents the balance of the FIDC registered in full in Cemig, and the senior units are presented as a debt under Loans and financings in Current and Non-current liabilities. Similarly, in the consolidation, the monetary updating of the FIDC has been recognized in full as a financial revenue, and in counterpart, the amount of the monetary updating of the senior units is recorded as a cost of debt.

11. FINANCIAL ASSETS OF THE CONCESSION

The Company’s concession contracts for distribution, transmission, gas and wind power generation are within the criteria for application of Technical Interpretation ICPC 01, which deals with the accounting of concessions.

The balances of the financial assets are as follows:

Consolidated	3/31/2011	12/31/2010
Distribution concessions	2,514,897	2,509,339
Gas concessions	535,743	287,425
New transmission concessions	4,432,636	4,399,627

b) Stockholding in Light

On the acquisition of Light, an amount of diminished value of the concession was recorded, corresponding to the difference between the amount paid by Rio Minas Energia S.A. (“RME”) and the book value of the interest in the Stockholders’ equity of Light in the amount of R$364,961, of which Cemig’s portion corresponds to 25.00%. This discount arises from the estimate of the results of future years as a function of the commercial operation of the electricity distribution and generation concessions, and is being amortized from October 2006 to May 2026, the date of the termination of the distribution concession, on a straight-line basis. The remaining amount of the diminished value of the concession is R$70,363 at March 31, 2011 (R$71,523 on December 31, 2010).

c) Added value on the acquisitions of equity interests

The goodwill on acquisition of the companies by the Company is the difference between the amount paid for the subsidiary or jointly-controlled subsidiary and the book value of the stake in their stockholders’ equity, arising from the added value of the concessions (Intangible asset) and of the Financial Assets of the Concession. The amortization of the added value of those assets that have defined useful life will take place during the remaining period of validity of the concessions.

d) Completion of the transaction to purchase shares in LIGHT

The payment for the acquisition by Cemig of the 25,494,500 common shares in Light S.A. (Light) owned by Andrade Gutierrez Concessões (“AGC”), representing 12.50% of the registered capital and voting stock of Light, was made on March 25, 2010. Cemig paid R$718.518 for the purchase, corresponding to R$29.54 per share. This amount results from the adjustment of the price stipulated in the Contract by the index published by Cetip (Securities Settlement and Custody Center) from December 1, 2009 to the present date, and from the deduction of the dividends of R$2.12 per share declared by Light at the Ordinary General Meeting of Stockholders completed on March 24, 2010.

On November 17, 2010, the payment for, and the transfer of, 1,081,649 common shares issued by Light S.A., owned by Andrade Gutierrez Concessões S.A., representing 0.53% do capital total and voting capital of Light S.A., to Cemig, was realized. The amount relating to the sale of the shares was R$ 30,471.

An Offsetting and Settlement Undertaking was signed between Cemig and AGC, stating that the debtor balance of the Generation Option premium payable by AGC should be paid in full to Cemig, against offsetting by the amounts owed by Cemig to AGC. For payment at sight, through the said compensation, Cemig granted AGC a discount in the amount of R$1,558. The net amount received by AGC was R$15,783.

The Company recognized a premium, in this transaction, in the amount of R$359,184, arising from the added value of the concession.

Additional option to buy shares in Light

On March 24, 2010, Enlighted Partners Venture Capital LLC (“Enlighted”) signed an option sale contract with Cemig under which Cemig granted to Enlighted the option to sell to Cemig the holding of Luce Investment Fund, owner of 75% of the unit shares in Luce Brasil Fundo de Investimentos em Participações (this fund owns 13.03% of the total capital of Light S.A.) — while Cemig had the option to indicate third parties to acquire the interest in Luce Investment Fund. As a result Cemig will be able to acquire 19,932,112 common shares issued by Light, representing 9.75% of its total and voting investment capital, for US$340,455,000, from which will be deducted any dividends and Interest on Equity paid or declared by Light from December 1, 2009 up to the date of the exercise of the option.

The option was exercised on October 6, 2010 by Enlighted, which gave notice of its decision to exercise its option to sell units of Luce Brasil Fundo de Investimento em Participações, as mentioned in the Material Announcement published on October 7, 2010.

The completion of this transaction, however, is conditional upon certain contractually established requirements being complied with, and also approval by the competent bodies, including ANEEL, the Brazilian electricity Regulator, and CADE, the Brazilian Monopolies authority, and also, where necessary, the financing agents and debenture holders of Light and of its subsidiaries.

e) Acquisition of a complementary stake in Transmissora Aliança de Energia Elétrica — Taesa

On May 6, 2010 Cemig GT made a Public Offer to Acquire shares and units from minority stockholders, through Transmissora Alterosa de Energia Elétrica. The transaction resulted in the acquisition of 24.42% of the shares until then held by the non-controlling stockholders, equivalent to 56.69% of the total capital of Taesa, for R$1,001,851, or R$15.57 per share.

The transaction was found to create a goodwill premium of R$523,367, corresponding to the added value of the financial asset to be received in the period of the concession specified by the regulator. The recovery of the goodwill will be amortized over the remaining period of validity of the concessions.

With this transaction Cemig GT, jointly with Fundo de Investimentos em Participação Coliseu, concluded the process of acquisition of Taesa. Some of the minority stockholders did not accept the public offer to acquire shares, and 4.72% of the shares of Taesa remained in circulation in the market.

On December 31, 2010 the companies Transmissora Alterosa de Energia Elétrica and Transmissora Alvorada Energia Elétrica were absorbed by Transmissora Aliança de Energia Elétrica — Taesa, with consequent extinction of the companies absorbed, which were succeeded in all their rights and obligations. The percentage holding of Cemig GT in Taesa was not changed due to the holding in Transmissora Alterosa de Energia Elétrica.

Table of Contents

The company has not identified any indications of loss of the recoverable value of its fixed assets. The concession contracts specify that at the end of the period of each concession the Concession-granting Power shall decide the amount to be indemnified to the Company. As a result Management believes that the accounting value of fixed assets that are not depreciated at the end of the concession period will be reimbursed by the Concession-granting Power.

ANEEL, under the Brazilian regulatory framework, is responsible for establishing the useful economic life of the generation and transmission assets of the electricity sector, with periodic reviews of the estimates. The rates established by the Agency are used in the processes of (i) tariff Review, and (ii) calculation of the indemnity at the end of the concession, and are recognized as a reasonable estimate of useful life of the assets of the concession. Hence, these rates were used as the basis for amortization of the Fixed Assets.

The average annual depreciation rates applied in the subsidiaries on March 31, 2011 are as follows:

Generation
Hydroelectric plants	2.49	%
Thermal plants	3.98	%
Administration and other	12.69	%
Telecoms	6.72	%

Consortia

The Company participates in consortia to operate electricity generation concessions, for which companies with an independent legal existence were not constituted to administer the object of the concession; and the controls of the specific portion equivalent to the investments made were/are maintained in the accounting of Cemig GT under Fixed Assets and Intangible Assets, , as follows:

The non-current Obligations for Pasep and Cofins taxes refer to the legal action challenging the constitutionality of the inclusion of the ICMS tax amount, already charged, inside the taxable amount for these taxes, and applying for offsetting of the amounts paid in the last 10 years. The Company and its subsidiaries Cemig D and Cemig GT obtained a Court injunction enabling it not to make the payment and authorizing payment into Court starting from 2008.

19. POST-EMPLOYMENT OBLIGATIONS

The Forluz Pension Fund

Cemig is a sponsor of Forluz — Forluminas Social Security Foundation, a non-profit legal entity whose object is to provide its associates and participants and their dependents and beneficiaries with a financial income to complement retirement and pension, in accordance with the Forluz pension plan they are subscribed to.

Table of Contents

The actuarial obligations and assets of the plan on December 31, 2004 were segregated between Cemig, Cemig GT and Cemig D on the basis of the allocation of the employees to each of these companies.

Forluz makes the following supplementary pension benefit plans available to its participants:

The Mixed Benefits Plan (“Plan B”): This is a defined-contribution plan at the phase of accumulation of funds, for retirement benefits for normal time of service, and as a defined-benefit plan for disability or death of participants still in active employment, and for receipt of benefits for time of contribution. The Sponsors match the basic monthly contributions of the participants. This is the only plan open for joining by new participants.

The contribution of the Sponsors to this plan is 27.52% for the portion with defined benefit characteristics, relating to the coverage for disability or death for the active participant, and this is used for amortization of the defined obligation through an actuarial calculation. The remaining 72.48%, relating to the portion of the plan with defined-contribution characteristics, goes to the nominal accounts of the participants and is recognized in the current income statement as and when the Company makes payments, under Personnel expenses.

Pension Benefits Balances Plan (“Plan A”): This includes all the currently employed and assisted participants who opted to migrate from the previous Defined Benefit Plan, and are entitled to a benefit proportional to those balances. For participants who are still working, this benefit has been deferred to the retirement date.

Cemig, Cemig GT and Cemig D also maintain, independently of the plans made available by Forluz, payments of part of the life insurance premium for the retirees, and contribute to a health plan and a dental plan for the employees, retirees and dependents, administered by Forluz.

Amortization of the actuarial obligations and recognition in the accounting statements

In this Explanatory Note the Company demonstrates the liabilities and the expenses in connection with the Retirement Supplement Plan, the Health Plan, the Dental Plan and Life Insurance in accordance with the terms of Technical Pronouncement CPC 33 (Benefits to employees) and an opinion prepared by independent actuaries based on December 31, 2010.

Table of Contents

The Company recognized an obligation payable for past actuarial deficits in the amount of R$866,850 on March 31, 2011 (R$868,178 on December 31, 2010). This amount was recognized as an obligation payable by Cemig and its subsidiaries Cemig GT and Cemig D, and is being amortized by June 2024, through monthly installments calculated by the system of constant installments (known as the “Price” Table). After the Third Amendment to the Forluz Agreement, the amounts began to be adjusted only by the IPCA Inflation Index (Amplified National Consumer Price Index) published by the Brazilian Geography and Statistics Institute (IBGE), plus 6% per year.

Thus, in cases of retirement obligations, the liability recognized in the balance sheet is the debt agreed with the foundation for amortization of the actuarial obligations, mentioned above, in view of the fact that it is greater than the liability to the pension fund contained in the actuary’s opinion. Since this debt must be paid even in the event of the Foundation having a surplus, the Company decided to record the debt in full against Stockholders’ equity on the transition date, and record the impacts relating to monetary updating and interest in Financial revenue (expenses).

The Braslight Pension Fund

Light is sponsor of Fundação de Seguridade Social Braslight, a non-profit private pension plan entity whose purpose is to guarantee retirement revenue to Company employees subscribed with the Foundation, and pension revenue to their dependents.

Braslight was instituted in April 1974, and has three plans — A, B and C — put in place in 1975, 1984 and 1998 respectively. About 96% of the active participants of the other plans have migrated to plan C.

In plans A and B the benefits are of the defined benefit type. In Plan C, which is of the mixed type, the programmable benefits (retirement not arising from invalidity, and the respective conversion into pension), during the capitalization phase are of the defined contribution type, without any link to the INSS, and the risk benefits (illness assistance, retirement for invalidity and pension for death of a participant who is still working, becomes invalid or receives illness assistance), as well as those of continued income, once granted, are of the defined benefit type.

On October 2, 2001, the Private Pension Plans Secretariat approved a contract for a solution to the technical deficit and the refinancing of the reserve to be amortized relating to the pension plans of Braslight, which were recorded in full. This is being paid in 300 monthly installments, starting from July 2001, updated by the variation of the IGP-DI inflation index and interest of 6,00% per year, totaling R$1,028,958 at 31 March, 2011 (R$1,016,185 on December 31, 2010). The effect in the consolidated results of the jointly-controlled subsidiary on March 31, 2011 is of the portion corresponding to 26.06% of this amount, as per proportional consolidation.

Cemig’s management believes that any disbursements in excess of the amounts provisioned, when the respective processes are completed, will not materially affect the result of operations or the individual and consolidated financial position of the Company.

The details on the provisions constituted are as follows:

(a) Employment-law matters

The complaints under the labor laws are basically disputes on overtime, additional amounts for dangerous work, property damages and pain and suffering.

Table of Contents

(b) ICMS 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. The 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 assessing the amounts involved in the infringement notices, believes that only part of these amounts represent a risk of loss in which, on the date of the financial statements, the existence of an obligation is more likely than not, and this part is provisioned in the amount of R$104,938 (R$94,400 on December 31, 2010). The proportional part of this obligation attributable to Cemig, in proportion to its ownership in Light, is R$27,351 (R$24,604 on December 31, 2010).

In December 1999 the National Social Security Institute (INSS) issued infringement notices against Light for alleged joint liability to withhold payments at source on amounts paid for services of contractors, and the applicability of the Social Security Contribution to employees’ profit shares.

Light challenges the legality of Law 7787/89, which increased the Social Security contribution percentage applying to payrolls, believing that it also changed the basis of calculations of Social Security contributions during the period July to September 1989. As a result of the Provisional Remedy given by the Court, the Company has offset the amounts payable for Social Security contribution.

The company assesses the chance of loss, in the actions referred to, as “probable”, and the amounts provisioned for the actions brought by the INSS were a total of R$16,764 on March 31, 2011 (R$16,562 on December 31, 2010).

(d) Environmental administrative proceedings

Cemig GT was served an infringement notice by the Minas Gerais State Forests Institute (IEF), alleging that it omitted to take measures to protect the fish population, causing fish deaths, as a result of the flow and operation of the machinery of the Três Marias Hydroelectric Plant. The Company has presented a defense and considers the chances, on the date of the financial statements, of there being a present obligation more likely than not, in the amount of R$3,252 on March 31, 2011 (R$3,185 on December 31, 2010), which has been duly provisioned.

(e) Other

Other civil actions are primarily claims for personal damages by individuals, mainly due to accidents allegedly occurring as a result of the Company’s business, and damages as a result of power outages. The provision at March 31, 2011 represents the potential loss on these claims.

(f) Contingent liabilities

(I) Acts of ANEEL

ANEEL filed an administrative action against Cemig stating that the company owes R$971,380 to the federal government (R$962,572 on December 31, 2010) as a result of an alleged error in the calculation of the credits under the CRC (Results Compensation) Account, which were, in the past, used to offset amounts owed to the federal government. On October 31, 2002 ANEEL issued a final administrative decision against Cemig. On January 9, 2004 the National Treasury issued an Official Collection Notice for the amount of the debit. Cemig did not make the payment because it believed that it has arguments on the merit for defense in the Courts and, thus, has not constituted a provision for this action. The Company assesses the chances of loss in this action as “possible”.

(II) Social security and tax obligations — indemnity of the “Anuênio” and profit shares.

In 2006 Cemig and its subsidiaries Cemig GT and Cemig D paid indemnities to their employees, totaling R$177,686, in exchange for the rights to future payments known as the “Anuênio” which would otherwise be incorporated, in the future, into salaries. The Company and its subsidiaries did not make payments of income tax and Social Security contribution in relation to this amount because they considered that these obligations are not applicable to amounts paid as indemnity. However, to avoid the risk of a future fine arising from a different interpretation by the federal tax authority and the National Social Security Institution, the company and its subsidiaries decided to file for orders of Mandamus to allow payment into Court of potential obligations under this heading, in the amount of R$121,834. These are posted in Deposits connected to legal actions.

Additionally, the Federal Revenue Service issued an Infringement Notice challenging the non-payment of the social security contributions (employer’s portion) on the “anuênio” amount indemnified, to prevent expiry by lapse of time, in the amount of R$16,754.

In September 2006, Cemig was notified by the INSS (National Social Security System) as a result of the non-payment of the Social Security contribution on the amounts paid as profit shares in the period 2000 to 2004, representing a total of R$195,368 (R$192,707 on December 31, 2010). The Company has appealed in administrative proceedings against the decision. No provision has been made for any losses. Cemig believes it has arguments of merit for defense, and the chances of loss in this action are assessed as “remote”.

Table of Contents

(III) ICMS tax

Cemig was served an infringement notice, as a co-guarantor party, in relation to sales of excess electricity by industrial consumers during the period of electricity rationing, in which the Minas Gerais State Tax Authority demanded payment of the ICMS tax on these transactions, in the amount of R$51,870 (R$51,159 on December 31, 2010). If the Company does have to pay the ICMS tax on these transactions, it can charge consumers the same amount to recover the amount of the tax plus any possible penalty charge. The Company assesses the chances of loss in this action as “possible”.

(IV) Regulatory contingency — CCEE

In an action dating from August 2002, AES Sul Distribuidora has challenged in the courts the criteria for accounting of electricity sale transactions in the wholesale electricity market during the period of rationing. It obtained a judgment in its favor in February 2006, which orders ANEEL, working with the CCEE, to comply with the claim by AES Sul and recalculate the settlement of the transactions during the rationing period, leaving out of account ANEEL’s Dispatch No. 288/2002. This measure was to be put into effect in the CCEE as from November 2008, which would have resulted in an additional disbursement for Cemig, for the expense on purchase of energy in the spot market, in the CCEE, in the amount of approximately R$113,861 (R$112,838 on December 31, 2010). On November 9, 2008 the Company obtained an injunction from the Regional Federal Appeal Court suspending the obligatory nature of the requirement to deposit the amount owed arising from the Special Financial Settlement carried out by the CCEE. Because of the above, no provision was constituted for this dispute, since the Company believes it has arguments on the merit for defense against this claim. The Company assesses the chances of loss in this action as “possible”.

(V) Civil claims — consumers

Several consumers and the Public Attorney of the State of Minas Gerais have brought civil actions against Cemig, contesting tariff increases applied in previous years, including: the tariff subsidies granted to low-income consumers, the extraordinary tariff recomposition and the inflation index used to increase the tariff for electricity in April 2003, and requesting 200% reimbursement on the amounts considered charge in error by the company. These proceeding were rejected by the courts in August 2010 and the cases were set aside, as expected by the Company’s counsel.

Table of Contents

The company is defendant in legal proceedings challenging the criteria for measurement of amounts to be charged in relation to the contribution for public illumination, in the total amount of R$650,254 (R$636,723 on December 31, 2010). The Company believes that it has arguments on the merit for defense in this dispute and as a result has not constituted provision for this action. The Company assesses the chances of loss in this action as “possible”.

(VI) Denial of offsetting of tax credits

The Federal Revenue Service did not homologate the statement filed by the Company of offsetting of credits for payments made unduly or in excess, in the amount of R$360,804, relating to various administrative taxation proceedings on offsetting of federal taxes.

Action in which the Company is potential creditor and success is rated “probable”

Pasep and Cofins — Widening of the calculation base

The holding company has legal proceedings challenging the enlargement (by Law 9718 of November 27, 1998) of the taxable basis for calculation of the Pasep and Cofins taxes, to apply to financial revenue and other non-operational revenues, in the period from 1999 to January 2004; and has a judgment in its favor at first instance. 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 registered in the Income statement will be R$188,131 (R$185,906 on December 31, 2010), net of income tax and Social Contribution Tax.

21. STOCKHOLDER’S EQUITY AND REMUNERATION TO STOCKHOLDERS

The Registered Capital of Cemig on March 31, 2011, is R$ 3,412,073, represented by 298,269,668 common shares and 384,144,914 preferred shares all with nominal unit value of R$5.00.

The Ordinary and Extraordinary General Meetings of Stockholders held on April 29, 2011, decided to distribute R$1,196,074 to the stockholders as dividends, comprising the obligatory dividend, of R$1,128,988, and complementary dividends of R$67,086.

The Company has dividends that will be received from its subsidiaries during 2011 for settlement of its obligations payable, including the dividends referred to above, and its other operational expenses.

a) Management of risks

Management of corporate risks is a management tool that is part of Corporate Governance practices and aligned with the process of planning, which sets the strategic objectives of the Company’s business.

Table of Contents

The Company has a Financial Risks Management Committee, the purpose of which is to implement guidelines and monitor the financial risk of transactions that might negatively affect the Company’s liquidity or profitability, recommending hedge protection strategies in relation to foreign exchange, interest rate and inflation risks. These have effects that are in line with the Company’s strategy.

A key aim of the Financial Risks Management Committee is to give predictability to the Company’s cash flow and position for a maximum 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:

Exchange rate risk

Cemig and its jointly-controlled subsidiaries as a whole are exposed to the risk of increase in exchange rates, especially of the US dollar and Euro against the Real, with significant impact on indebtedness, profit and cash flow. For the purpose of reducing its exposure to increases in exchange rates, on March 31, 2011 and December 31, 2010, Cemig had hedge transactions contracted, which are described in more detail in item “b”.

The net exposure to exchange rates is as follows:

	Consolidated and Holding company

Loans and financings	174,342		175,963

Other	2,539		2,675
Net liability exposure	14,386		15,301
	144,325		145,838

Sensitivity analysis

Based on its financial consultants, the Company estimates that, in a probable scenario, the appreciation of the exchange rates of foreign currencies against the Real on March 31, 2012 will be 5.42% for the Dollar (i.e. to US$1:R$ 1.717) and 1.95% for the Euro (to €1:R$ 2.358). The Company has made a sensitivity analysis of the effects on its results arising from increases of 25% and 50% in the exchange rate, in relation to the scenario that it rates as “probable” — designating these alternative scenarios as “possible” and “remote”, respectively.

Interest rate risk

Cemig and its jointly-controlled subsidiaries were exposed to the risk of increase in international interest rates, affecting Loans and financings in foreign currency with floating interest rates (principally Libor), in the amount of R$57,860 at December 31, 2011 (R$58,905 on December 31, 2010).

As to the risk of increase in domestic Brazilian interest rates, the Company’s exposure arises from its net liabilities indexed to variation in the Selic and CDI rates, as follows:

Net liability exposure	(5,014,278	)	(4,815,477	)

Sensitivity analysis

In relation to the most significant risk of increase in interest rates, the Company estimates that, in a probable scenario, the Selic rate on March 31, 2012 will be 11.75%. The Company has made a sensitivity analysis of the effects on its results arising from increases of 25% and 50% in the Selic rate, in relation to the scenario that it considers as “Probable” — designating these alternative 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, as described in the Hedging Policy.

Credit risk

The risk arising from the possibility of Cemig and its subsidiaries incurring losses as a result of difficulty in receiving amounts billed to its clients 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.

In relation to the risk of the Company suffering losses resulting from declaration of insolvency by a financial institution where it makes deposits, a Cash Investment Policy was approved, and has been in force since 2004, in which each institution is analyzed according to criteria of current liquidity, degree of leverage, degree of default, profitability, and costs, and also analysis by three financial risk rating agencies. The institutions receive maximum limits of allocation of funds, and these are reviewed, both periodically and also in the event of any change in the macroeconomic scenarios of the Brazilian economy.

Energy scarcity risk

The electricity sold is generated, substantially, by hydroelectric power plants. A prolonged period of scarcity of rainfall could result in reduction of the volume of water in the reservoirs of the generation plants, limiting recovery of their volume, and resulting in losses as a result of increased costs for acquisition of energy, or reduction of revenues in the event of adoption of another rationing program, like the one put in place in 2001.

Risk of non-renewal of concessions

The Company has concessions for commercial operation of generation, transmission and distribution services, and its Management expects that they will be renewed by ANEEL and/or the Mining and Energy Ministry. If the regulatory bodies do not grant the applications for renewals of these concessions, or if they decide to renew them upon imposition of additional costs for the Company (“concessions for consideration”) or setting of a price ceiling, the present levels of profitability and activity could be altered.

Table of Contents

The Company has not suffered any significant negative impact as a result of events related to the risks described above.

Liquidity risk

Cemig has sufficient cash flow to cover its short-term requirements and for its program of acquisitions and investments.

The principal indicators of financial covenants, which compare the requirements for debt and cash generation (Ebitda) in the 1st quarter of 2011, show the Company’s liquidity profile.

Also, just as important as the quality of the business’s operational cash flow is management of the liquidity risk, with a group of methodologies, procedures and instruments that are coherent with the complexity of the business and applied in permanent control of the financial processes, so as to guarantee appropriate risk management.

The structure adopted for the management of Cemig’s risks is matrix-based and decentralized, but with centralized monitoring, which generates material information with a systemic vision. This structure enables the process of management of corporate risks to interact with other components 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 — as well as complying with the Sarbanes-Oxley Law, and the requirements of Internal Auditing.

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.

In the operational aspect, Cemig adopts rigid and conservative principles in management of cash flow, establishing financial covenants in its Bylaws, that are more restrictive than those contained in the debt contracts, and a minimum cash amount for each one of the companies, stipulated as 5% of Ebitda.

In its management of liquidity risk, Cemig carries out permanent, and conservative, monitoring of its cash flow, in a budget-based vision, which projects balances monthly, for each one of the companies, over a period of 12 months, and monitoring of daily liquidity, which projects balances daily for 180 days.

The short-term allocations also obey rigid principles established in the Cash Investment Policy, handling up to 20% of the funds in exclusive private credit investment funds, without market risk, with the excess margin applied directly in bank CDs or repo transactions remunerated at the CDI rate.

Table of Contents

In the management of cash investments, the Company seeks to obtain profitability on its transactions based on a rigid analysis of bank credit, obeying operational limits with banks, based on assessments of the banks that take into account ratings, exposures and equity. It also seeks returns by working on lengthening of the tenors of cash investments, always on the basis of the central principle, which is control of liquidity.

b) Financial instruments — Derivatives

The derivative instruments contracted by Cemig and its subsidiaries have the purpose of protecting their operations against the risks arising from foreign exchange variation and are not used for speculative purposes.

The principal amounts of the transactions in derivatives are not posted in the Balance sheet, since they refer to transactions that do not require cash payments of the principal: only the gains or losses that actually occur are recorded. On March 31, 2011 the net result of these transactions was a loss of R$9,638 (vs. loss of R$6,072 on December 31, 2010), recorded in Financial revenues (expenses).

The Company has a Financial Risks Management Committee, 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 negatively affect its liquidity and profitability. This Committee aims, when implementing Action Plans, to set Guidelines for proactive operation in the environment of financial risks.

Method of calculation of the fair value of positions

The fair value of cash investments has been calculated taking into consideration the market prices of the security, or market information that makes such calculation possible, and future interest rates and FX rates applying to similar securities. The market value of the security corresponds to its value at maturity, brought to present value by the discount factor obtained from the market yield curve, in Reais.

27. MEASUREMENT AT FAIR VALUE

The Company adopts measurement at fair value of its financial assets and liabilities. Fair value is measured at market value, based on assumptions in which the participants in the market are able to measure an asset or liability. To increase coherence and comparability, we use a “hierarchy of fair value” that puts the mechanism used for measurement into three levels by order of priority, as follows:

· Level 1. With active market: Quoted price — A financial instrument is considered as quoted on an active market if the prices quoted are promptly and regularly made available by an exchange or organized over-the-counter market, by operators, brokers, or a market association, or by entities whose objective is to publicize prices, or by regulatory agencies, and provided that these prices represent market transactions that occur regularly between independent parties, without favoring any party.

Table of Contents

· Level 2. Without active market: Valuation technique — For an instrument that does not have an active market the fair value should be ascertained using a valuation/pricing methodology. Criteria that can be used include data on the current fair price of another instrument that is substantially the same, analysis of discounted cash flow, and option pricing models. The aim of a valuation technique is to establish what would be the price of the transaction on the date of measurement in an exchange of value not affected by any extraneous interest, and motivated by business considerations.

· Level 3. Without active market: Equity security — Fair value of investments in equity securities that do not have market prices quoted on an active market and of derivatives that are linked to them and which are to be settled by the delivery of non-quoted equity assets.

This is a summary of the instruments that are measured at fair value:

		Fair value at March 31, 2011

Methodology of calculation of fair value

a) 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, taking into account future fixed-income market and FX rates applicable to similar securities. The market value of the security corresponds to its maturity value brought to present value by the discount factor obtained from the market yield curve in Reais.

b) Swap contracts: The criterion for marking to market of transactions in derivatives consists of establishing the present price 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 the difference between the market values of each one of their end points, adjusted by their indexor. Pricing of a swap on its CDI (interbank CD) side is calculated from the start date of the transaction up to the date concerned, considering the future forecast for this index or made by the market on the date of measurement. 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.

28. STATEMENTS OF ADDED VALUE (DVAs)

In accordance with a requirement applied by the CVM to listed companies, and with the status of additional information for the purposes of IFRS, the Company has prepared individual and consolidated statements of added value.

These statements, which are based on macroeconomic concepts, seek to present the portion of the Group in the formation of GDP by calculation of the respective amount both added by the Group and received by other entities, and the distribution of these amounts to their employees, spheres of government, parties leasing assets, creditors under loans, financings and debt securities, controlling and non-controlling stockholders, and other remunerations that constitute transfer of wealth to third parties. The said added value represents the overall wealth created by the Group, measured by the revenues from sales of goods and services provided, less the respective inputs acquired from third parties, also including the added value produced by third parties and transferred to the entity.

29. SUBSEQUENT EVENTS

a) The 2011 Tariff Adjustment of Cemig D

On April 8, 2011 ANEEL published the result of the Tariff Adjustment of Cemig D. The Company’s tariffs were differentiated by voltage level, and the average impact was an increase of 6.04%, effective on that date.

ECONOMIC AND FINANCIAL PERFORMANCE – CONSOLIDATED

Adoption of International Financial Reporting Standards

The results below are reported under the new Brazilian accounting practices, resulting from the process of harmonization of Brazilian accounting rules with International Financial Reporting Standards. For this reason the results for the first quarter of 2010 have been restated to reflect these changes and to allow comparability with the first quarter of 2011.

Profit in the period

Cemig reports consolidated net profit for 1Q11 of R$526,151, which compares with R$520,066 in 1Q10, an increase of 1.17% . This mainly reflects the higher revenue due to volume of electricity sold being 3.11% higher year-on-year, in turn mainly due to higher industrial activity; and also to revenue from use of the grid being 3.51% higher year-on-year, principally because of the addition of the transmission company Taesa to the network in May 2010.

(Method of calculation not reviewed by external auditors)

Cemig’s Ebitda in 1Q11 was 11% higher than in 1Q10.

EBITDA - R$ ’000	3/31/2011	3/31/2010	Change, %
Profit (loss) for the year	526,151	520,066	1.17
+ Provision for income tax and Social Contribution tax	250,492	300,806	(16,73	)
+ Financial revenues (expenses)	282,819	129,446	118.48
+ Depreciation and amortization	232,797	213,904	8.83
= Ebitda	1,292,259	1,164,222	11.00

The higher Ebitda in 1Q11 than in 1Q10 mainly reflects Revenue 17.69% higher, partially offset by Operational costs and expenses (excluding depreciation and amortization) 22.23% higher. The higher Operational costs and expenses in 1Q11 than in 1Q10 are reflected in Ebitda margin, which was 40.46% in 1Q10, and 38.16% in 1Q10.

Revenue from supply of electricity

Gross revenue from supply of electricity in 1Q11 was R$3,969,051, 14.53% more than in 1Q10 (R$3,465,493).

Table of Contents

Final consumers

The revenue from electricity sold to final consumers in 1Q10, excluding the group’s own consumption, was R$3,498,847, compared to R$3,097,476 in the first quarter of 2010. The main factors in this result are:

· The volume of energy invoiced to final consumers (excluding Cemig’s own consumption) was 15.60% higher.

· There was a tariff increase for Cemig D with average effect on consumer tariffs of 1.67%, effective April 8, 2010.

· There were price adjustment in contracts for sale of electricity, most of which are indexed to the IGP–M inflation index.

· Is spite of these effects, revenue was up 14.53%, mainly because of the impacts arising from regulatory assets and liabilities that were transferred to the tariffs in the periods concerned.

Electricity sold to final consumers (MWh)

Total	12,414,948	10,740,009	15.60

Wholesale revenue

The volume of electricity sold to other concession holders in 1Q11 was 5.35% higher than in 1Q10, and average price in these sales was 4.56% higher, at R$106.95/MWh in 2011, compared to R$102.29/MWh in 2010. As a result, revenue from wholesale supply to other concession holders was 10.15% higher year-on-year, at R$364,724 in 2011, than in 2010 (R$331,127). Revenues from energy sold to other concession holders totaled R$3,410,217 in 1Q11, compared to R$3,237,078 million in 1Q10.

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 56.51% higher in 1Q11, at R$524,375, compared to R$335,042 in 1Q10. This revenue comes from charges made to Free Consumers on energy sold by other agents of the electricity sector, and its increase arises from a higher volume of transport of energy for free consumers, a consequence of the recovery of industrial activity and of migration of captive clients to the free market.

Revenue from use of the transmission grid

Revenue from use of the network, at R$329,028, was 3.51% (R$11,153) higher year-on-year than in 1Q10 (R$317,875).

This revenue is from the transmission capacity of Cemig GT made available to the national grid, and also from the jointly-controlled transmission subsidiaries, among which we highlight the transmission groups known as TBE and Taesa.

The increase in this revenue in 2011 is mainly due to acquisition of an interest in Taesa, in May 2010, through a public offer to acquire shares, which increased these revenues in 1Q11.

Deductions from operational revenues

Deductions from operational revenues in 1Q11 totaled R$1,647,650, or 18.27% more than in 1Q10 (R$1,393,136). The main variations in these deductions from revenue between the two years are:

The Fuel Consumption Account – CCC

The deduction for the CCC charge was R$157,302 in 1Q11, compared to R$98,942 in 1Q10, an increase of 58.98% . 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 an ANEEL Resolution.

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. For the portion relating to transmission services the Company charges the CCC amount to Free Consumers on their invoices and passes it on to Eletrobrás.

CDE – Energy Development Account

The deduction from revenue for the CDE charge was R$122,855 in 1Q11, compared to R$110,176 in 1Q10, an increase of 11.51% . These payments are specified by a Resolution issued by the regulator, ANEEL. 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. For the portion related to transmission services the Company merely acts as a channel for the CDE amount, charging it to Free Consumers on their invoices and paying it on to Eletrobrás.

The other deductions from revenue operate as taxes, calculated as a percentage of amounts invoiced. Hence their variations are substantially proportional to the changes in revenue.

Operational costs and expenses (excluding Financial revenue/expenses)

Operational costs and expenses (excluding Net financial revenue (expenses)) totaled R$2,327,125 in 1Q11, 20.74% more than in 1Q10 (R$1,927,535). This is mainly due to increases in the costs of Electricity bought for resale, and Outsourced services. There is more information on this in Explanatory Note 23 to the Consolidated Quarterly Information.

The following paragraphs outline the main variations in expenses:

Electricity bought for resale

The expense on electricity bought for resale in 1Q11 was R$1,075,760, or 49.84% more than in 1Q10 (R$717,941). The higher amount is basically due to a higher volume of selling activity by Cemig GT – reflected in higher revenues in the distribution activity. 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. There is more information on this in Explanatory Note 23 to the Consolidated Quarterly Information.

Charges for use of the transmission grid

The expense on charges for use of the transmission network in 1Q11 was R$189,614, 1.44% more than in 1Q10 (R$186,921).

These charges, set by an ANEEL Resolution, are payable by electricity distribution and generation agents for use of the facilities that are components of the national grid. 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 totaled R$281,967 in 1Q11, 4.27% less than in 1Q10 (R$294,543). This is largely due to the reduction of the number for employees from 2010 to 2011, as a result of the Company’s Voluntary Retirement Program, the effect being partly offset by the average salary increase of 7% agreed in November 2010, in the negotiations for the annual Collective Work Agreement for 2010–11.

Depreciation and amortization

Depreciation and amortization was 8.83% higher year-on-year: R$232,797 in 1Q11, compared to R$213,904 in 1Q10. The increase effectively reflects the Company’s increased investment program, mainly in the distribution business.

Table of Contents

Post-employment obligations

Expenses on post-employment obligations totaled R$30,888 in 1Q11, 10.69% more than in 1Q10 (R$27,905). This expense represents the updating of the obligation, calculated in accordance with an actuarial opinion prepared by external consultants.

Operational provisions

Operational provisions totaled R$41,068 in 1Q11, compared to R$23,148 in 1Q10, an increase of 77.42% . The higher figure mainly reflects a reversal of R$11,042 in 1Q10, of the provision for civil lawsuits on the subject of tariff increases, due to finalization of the cases. Further information is given in Explanatory Note 23 to the Consolidated Quarterly Information.

Gas purchased for resale

The cost of gas purchased for resale was R$62,366 in 1Q11, 26.04% higher than in 1Q10 (R$49,481). This mainly reflects higher quantity of gas bought by Gasmig since Gasmig sold more gas in 1Q11, as a consequence of increased industrial activity.

Financial revenues (expenses)

The company posted net financial expenses of R$282,819 for 1Q11, which compares with net financial expenses of R$129,446 in 1Q10. The main factors in this financial result are:

· Higher expense on costs of loans and financings: R$302,699 in 1Q11, compared to R$231,034 in 1Q10. The higher figure reflects entry of new financings, one of the most important being the raising of R$600,000 by Cemig D in May 2010; and also the higher aggregate CDI rate over 1Q11 than in 1Q10 – the result of the increase in the Selic Rate by the Central Bank.

· Increase in the expense of monetary variation on Loans and financings in Brazilian currency: R$50,964 in 1Q11, compared to R$31,975 in 1Q10. This increase is due, substantially, to the higher volume of funds indexed to the IPCA in first quarter 2011 than in 1Q10, arising from financings obtained at the end of 1st quarter 2010.

For a breakdown of financial revenues and expenses, please see Explanatory Note 24 to the Consolidated Quarterly Information.

Income tax and Social Contribution tax

In 1Q11, Cemig posted expenses on income tax and Social Contribution tax of R$250,492, which was 32.25% of the pre-tax profit of R$776,643. In 1Q10, Cemig posted expenses on income tax and Social Contribution tax of R$300,806, representing 36.65% of the pre-tax profit of R$820,872. These effective rates are reconciled with the nominal rates in Note 8 to the Consolidated Quarterly Information.

Investor Relations

In 2010, through strategic activities aiming to enable investors and stockholders to make a correct valuation of our businesses and our prospects for growth and addition of value, we increased Cemig’s exposure to the Brazilian and global capital markets as a leading company in its sector.

We keep up a constant and proactive flow of communication with Cemig’s investor market, strengthening our credibility, seeking to increase interest in our securities and ensure that investors are satisfied with them.

Our results are published in presentations given by video webcasts and conference calls, with simultaneous translation into English, at which members of the Executive Board are always present – developing an increasingly transparent relationship, in line with the best corporate governance practices.

To serve our stockholders, who are spread over 40 countries, and facilitate optimum coverage of investors, Cemig was present in Brazil and worldwide at innumerable seminars, conferences, investor meetings, congresses, and roadshows; and also held video and telephone conference calls with analysts, investors and other parties interested in the capital markets.

At the end of May, for the 15th year running, we held our now traditional Cemig Meeting with the Capital Markets and Investors, together with Apimec, the Brazilian Capital Markets and Analysts’ Association, in the town of Belo Horizonte, Minas Gerais, where these professionals once again had the opportunity to interact with the Company’s directors and principal executives.

Corporate governance

Our corporate governance model is based on principles of transparency, equity and accountability, focusing on clear definition of the roles and responsibilities of the Board of Directors and the Executive Board in the formulation, approval and execution of policies and guidelines for managing the company’s business.

We seek sustainable development of the Company through balance between the economic, financial, environmental and social aspects of our enterprises, aiming to improve the relationship with our stockholders, clients, and employees, the public at large and other stakeholders.

Cemig’s preferred and common shares have been listed under Corporate Governance Level 1 on the São Paulo Stock Exchange since 2001 (with tickers CMIG3 and CMIG4

Table of Contents

respectively). This classification represents a guarantee to our stockholders of optimum reporting of information, and also that stockholdings are relatively widely dispersed.

Because Cemig has ADRs (American Depository Receipts) listed on the New York Stock Exchange — representing both the preferred shares (with ticker CIG) and the common shares (with ticker CIG.C) — it is also subject to the regulations of the US Securities and Exchange Commission (SEC) and the New York Stock Exchange Listed Companies Manual.

Our preferred shares have been listed on the Latibex of the Madrid stock exchange (with ticker XCMIG) since 2002.

Since the end of 2006 our material procedures related to preparation of the Consolidated Financial Statements have been compliant with the requirements of Section 404 of the Sarbanes-Oxley law of the US.

As well as our dividend policy, our bylaws include the targets of the Strategic Plan, as follows :

· – to keep consolidated indebtedness equal to or less than 2 times Ebitda.

· – to keep the consolidated ratio (Net debt) / (Net debt + Stockholders’ equity) equal to or less than 40%.

· – to limit consolidated funds in Current assets to 5% of Ebitda.

· – consolidated funds allocated to capital expenditure in each business year to be limited to 40% of Ebitda (exceptionally, 65% in 2006 and 55% in 2007).

· – to invest only in distribution, generation and transmission projects which offer real minimum internal rates of return equal to or greater than those specified in the company’s Long-Term Strategic Plan, subject to the legal obligations.

· – to limit the expenses of the subsidiary Cemig Distribuição (Cemig D), and of any subsidiary which operates in distribution of electricity, to amounts not greater than the amounts recognized in the tariff adjustments and reviews.

· The Board of Directors may authorize numbers in excess of these standards, in response to temporary needs, up to the following limits:

· – consolidated debt: maximum of 2.5 times Ebitda.

· – consolidated ratio (Net debt) / (Net debt + Stockholders’ equity): maximum of 50%.

The Sarbanes-Oxley Law

Cemig obtained the first certification of its internal controls for mitigation of risks associated with 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). It is included in the 20-F Form relating to the business year ending December 31, 2006, filed with the US Securities and Exchange Commission (SEC) on July 23, 2007.

Table of Contents

A link was established between the controls and the potentially significant accounting records, in the financial statements for 2009. Also, the design of the processes and key controls for ensuring mitigation of the risks associated with the preparation and disclosure of the financial statements for the year ended December 31, 2009 was validated.

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 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. The result has been a perceived improvement in the effectiveness of the strategic controls, a commitment to implementation of the mitigating action plans proposed and, consequently, reduction of the financial impact and the 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, 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.

Functional structure

The main determining factor for the option adopted for functional structure is decentralized management by Risk Managers. This expresses the corporative and matricidal 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.

Table of Contents

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 approval by Cemig’s Board of Directors, in May 2004, of the Statement of Ethical Principles and Code of Professional Conduct (http://ri.cemig.com.br), established a list of 11 principles of ethical conduct and value incorporated into Cemig’s company culture, and was an important step in perfecting the company’s internal system of corporate government and increasing our 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 and decision on any possible non-compliances with the document.

In December 2006 we created the Information Channel, to be used only by Cemig employees and workers. It enabled the Ethics Committee to receive anonymous reports, via an open channel on our intranet — the Anonymous Information Channel. These reports can deal with any type of irregular practice contrary to the Company’s interest, such as: financial fraud, including unauthorized alteration of documents, changing or suppression of financial, tax or accounting documents; undue appropriation of goods or resources; receipt of undue advantage by managers or employees; irregular contracting; or other illegal practices.

The Ethics Committee

This was created on August 12, 2004, with three sitting members and three substitute members, and is responsible for management (interpreting, publicizing, applying and updating) of the Code of Professional Conduct.

It 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. They are sent to the address: Cemig, Av. Barbacena 1200, SA/17°/B2 — accompanied by indication of the corresponding means of proof (witnesses,

Table of Contents

documents or other appropriate and sufficient 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 Information 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.

The Statement of Ethical Principles and Code of Professional Conduct of Cemig is based on 11 Principles, which express the ethical conduct and values incorporated into its culture. It is available on our website: http://ri.cemig.com.br.

REPORT ON REVIEW OF THE QUARTERLY INFORMATION

To the Board of Directors and Stockholders of

Companhia Energética de Minas Gerais – Cemig

Belo Horizonte, Minas Gerais

Introduction

We have reviewed the interim individual and consolidated accounting information of Companhia Energética de Minas Gerais – Cemig, contained in the Quarterly Information (ITR) Form, relating to the quarter ending on March 31, 2011. This comprises the balance sheet and the related income statements, statement of comprehensive income, statement of changes in stockholders’ equity and statements of cash flows for the quarter ending on that date, including the explanatory notes.

The management is responsible for preparation of the individual interim accounting statements in accordance with Technical Pronouncement CPC 21 — Interim Reporting; for preparation of the consolidated interim accounting information in accordance with CPC 21 and the international rules of IAS 34 — Interim Financial Reporting, issued by the International Accounting Standards Board — IASB; and also for the presentation of that information in a way that is coherent with the rules issued by the Brazilian Securities Commission (CVM — Comissão de Valores Mobiliários) that are applicable to preparation of the Quarterly Information (ITR). Our responsibility is to express a conclusion on this interim accounting information based on our review.

Scope of the review

We have conducted our review in accordance with the Brazilian and international rules on review of interim information (NBC TR 2410 — Review of Interim Information by the Entity’s Auditor, and ISRE 2410 — Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of the interim information consists of: asking of questions, principally of the people responsible for the financial and accounting subjects; and application of analytical procedures and other procedures of review. The scope of a review is significantly less than that of an audit conducted in accordance with the rules of auditing and, consequently, did not enable us to be certain that we became aware of all the significant subjects that could be identified in an audit. Thus, we have not expressed an audit opinion.

Conclusion on the individual interim accounting information

Based on our review, we have not become aware of any fact that could lead us to believe that the individual interim accounting information included in the Quarterly Information has not been prepared, in all material aspects, in accordance with CPC 21 applicable to the preparation of Quarterly Information (ITR)and presented in a way that is coherent with the rules issued by the CVM.

Table of Contents

Conclusion about the consolidated interim accounting information

Based on our review, we are not aware of any fact that could lead us to believe that the consolidated interim accounting information included in the Quarterly Information referred to above has not been prepared, in all material aspects, in accordance with CPC 21 and IAS 34 applicable to the preparation of Quarterly Information (ITR) and presented in a way that is coherent with the rules issued by the CVM.

Point of emphasis

The indirectly jointly-controlled subsidiary Madeira Energia S.A. — Mesa and its subsidiary have incurred expenses related to development of the project for construction of the Santo Antonio hydroelectric power plant which, in accordance with the financial projections prepared by its Management, should be absorbed by the future revenues from the operations. The realization of the fixed asset constituted by the said expenditure, which on March 31, 2011 totaled R$ 8,066.8 billion, will, in accordance with management’s expectations, take place as from the start of operation, planned for December 2011. The amount proportionate to the Company is R$ 806.7 million in Fixed assets on March 31, 2011.
