1 Operations

Companhia Paranaense de Energia (Copel, Company or Parent Company), with its head office located at Rua Coronel Dulcídio, 800, Curitiba - State of Paraná, is a publicly-held mixed capital company controlled by the State of Paraná and its shares are traded at Corporate Governance Level 1 of the Special Listing Segments of B3 S.A. - Brasil, Bolsa Balcão Stock Exchange and also on the New York Stock Exchange (NYSE) and on the Madrid Stock Exchange in the Latin American segment (Latibex).

The core activities of Copel and its subsidiaries, which are regulated by the Brazilian Electricity Regulatory Agency (ANEEL), linked to the Brazilian Ministry of Mines and Energy (MME), are to carry out research, study, planning, and asset building activities related to the generation, transformation, distribution and trading of energy in any of its forms, primarily electricity. Furthermore, Copel participates in consortiums and in private sector and mixed-capital companies for the purpose of engaging in activities, primarily in the fields of energy, telecommunications and natural gas.

1.1 Copel’s equity interests

Copel has direct and indirect interests in subsidiaries (1.1.1), joint ventures (1.1.2), associates (1.1.3) and joint operations (1.1.4).

1.1.1 Subsidiaries

1.1.2 Joint ventures

1.1.3 Associates

1.1.4 Joint operations (consortiums)

2 Concessions and Authorizations

2.1 Concession contracts or authorizations obtained by Copel

2.1.1 Compagás

Compagás is a party to a concession agreement entered into with the Concession Grantor, the State of Paraná, setting July 6, 2024 as the expiration date of the concession.

On December 7, 2017, the State of Paraná published Supplementary Law 205, introducing a new interpretation of the expiration of the concession, understanding that expiration will be on January 20, 2019. Considering that up to this date the extension/bidding of the concession has not yet occurred, the law provides that the concession operator may, after the expiration of the term, remain responsible for its performance until the assumption of the new concession operator, subject to the conditions established.

The Management of Compagás, its Parent company and other shareholders are challenging the effects of the aforesaid law since they understand that it conflicts with the provisions of the concession agreement currently in force. Compagás filed a lawsuit challenging the early termination of the concession and, on October 30, 2018, a preliminary injunction was granted. The Company is awaiting the trial of the merit of the case.

Considering that the lawsuit continues outstanding and the law continues in force, it was necessary to consider these effects in the financial statements. The impacts recorded are as follows:

Management will continue to make its best efforts to protect the Company’s interests, aiming at appropriately settle the impacts of the new interpretation given by the Concession Grantor and find alternatives necessary to maintain the concession in a sustainable manner.

2.2 Concession contracts or authorizations obtained by Copel Get and its investees

3 Basis of Preparation

3.1 Statement of compliance

The quarterly information is being presented considering the provisions of CPC 21(R1) and IAS 34 – Interim Financial Reporting. Consequently, certain information contained in the notes to the financial statements for the year ended December 31, 2018, and which was not subject to modifications in the first three months of 2019, is not being presented. Therefore, this quarterly information should be read together with the financial statements as at December 31, 2018, available on the websites of the Brazilian Securities and Exchange Commission - CVM and Copel.

The Company’s Management believes that all the relevant information used in its management is evidenced in the individual and consolidated quarterly information.

The quarterly information was approved by Management and authorized for issue on May 14, 2019.

3.2 Functional and presentation currency

The quarterly information is presented in Brazilian Reais, which is the functional and presentation currency of the Company. Balances herein have been rounded to the nearest thousand, unless otherwise indicated.

3.3 Basis of measurement

The quarterly information was prepared based on the historical cost, except for certain financial instruments and investments measured at fair value, as described in the respective accounting policies and notes.

3.4 Use of estimates and judgments

In the preparation of this quarterly information, Management used judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses of Copel and its subsidiaries. Actual results may differ from those estimates.

Estimates and assumptions are reviewed on a continuous basis. Changes in estimates are recognized in the period in which they occur.

Information about the use of estimates and judgment referring to the adoption of accounting policies which impact the amounts recognized in the quarterly information is the same as that disclosed in note 3.4 to the financial statements at December 31, 2018, excepting the information disclosed in note 4.1.1 to this quarterly information.

3.5 Management’s judgment on going concern

Management has concluded that there are no material uncertainties that cast doubt on the Company’s ability to continue as a going concern. No events or conditions were identified that, individually or in the aggregate, may raise significant doubts on its ability to continue as a going concern.

The main bases of judgment used for such conclusion are: (i) main activities resulting from long-term concessions; (ii) robust equity; (iii) strong operating cash generation, including financial capacity to settle commitments entered into with financial institutions; (iv) historical profitability; and (v) fulfillment of the objectives and targets set forth in the Company's Strategic Planning, which is approved by Management, monitored and reviewed periodically, seeking the continuity of its activities.

3.6 Restatement

CPC 47 / IFRS 15 – Clarifications to IFRS 15 – Revenue from Contracts with Customers and CPC 48 / IFRS 9 – Financial Instruments have been effective since January 1, 2018. During the closing of fiscal year 2018, specifically for the electricity transmission activity, the Company reassessed its operations in light of the new accounting standards and concluded that the balance of the public electricity transmission contracts signed with the Concession Grantor to build, operate and maintain the high voltage lines and substations should be classified and presented as contract assets instead of as financial assets, as they were previously presented, since the consideration for this asset is conditional upon fulfillment of other contractual performance obligations.

For this quarterly information, the new understanding had an impact on the result for the first quarter of 2018, due to the equity valuation adjustment in the remeasurement of assets of Copel GeT's equity interests, and on the statement of cash flows, due to the reclassification of the contract assets, previously classified with intangible assets. The effects on the financial statements, restated for purposes of comparison, are shown below:

4 Significant Accounting Policies

The Company’s accounting policies are consistent with those presented in the financial statements for the year ended December 31, 2018, except for the policies disclosed in note 4.1.

4.1 Standards applicable to the Company effective January 1, 2019

4.1.1 CPC 06 (R2)/IFRS 16 - Leases

The pronouncement replaces CPC 06 (R1) / IAS 17 - Leases, as well as related interpretations (ICPC 03 / IFRIC 4, SIC 15 and SIC 27). The adoption of the new standard eliminates the operating lease accounting for the lessee, presenting a single lease model consisting of initially recognizing all leases in assets and liabilities at present value; and recognizing the amortization of the right to use the asset and lease interest separately in the statement of income.

Transition method

The Company applied the modified retrospective transition method, which does not require the presentation of comparative information, and the liability and the right-of-use asset are recognized at the present value of the remaining installments. Accordingly, the information for prior years continues being presented in accordance with the previous standard.

The Company analyzed its operating lease contracts and applied this pronouncement only to contracts in force on January 1, 2019 and that have been previously identified as leases.

In conformity with CPC 06 (R2) / IFRS 16, the Company elected to adopt the recognition exemptions foreseen for short-term leases (lease term of 12 months or less) and low value assets leases, such as computers, printers and mobile devices of less than R$18. These contracts are recognized as operating lease costs and/or expenses on a straight line basis as provided for in the standard, over the lease contract term.

The Company has land lease contracts for the development of wind power generation projects that provide for minimum lease payments during the study/construction period and variable lease payments during the period of commercial operation. For lease contracts that at the date of application of the standard are subject to minimum payments, the Company recognized a right-of-use asset and a lease liability. Lease agreements that are already in commercial operation are recognized by the Company in its statement of income, when the event or condition is fulfilled, as leases and rentals, in operating costs and/or expenses.

Use of judgment

Lessee’s incremental borrowing rate

For all lease contracts with related parties and third parties, the Company considered the interest rate required to acquire assets in similar conditions of those leased as of the date of execution of the lease contract. The rate adopted by the Company considers the cost of the last borrowing taken out, based on the Interbank Deposit Certificate (CDI) rate plus a risk spread applicable to the Company. On initial adoption, the rate used was 9.10% p.a.

Lease term for contracts with indefinite term.

The Company has lease contracts with indefinite term. For these contracts, the estimated term adopted considered a maximum term extension by 60 months.

Effects from initial application

The new requirements of CPC 06 (R2)/IFRS 16 generated the following impacts on the recognition and presentation of lease and rental contracts.

The effects from initial adoption are presented in note 28.

4.1.2 ICPC 22/IFRIC 23 – Uncertainty Over Income Tax Treatment

The interpretation explains how to apply the recognition and measurement requirements of CPC 32 – Income Taxes when there is uncertainty over a tax treatment. In accordance with certain requirements, such as where the tax authority is most likely not to accept certain treatment, the entity shall recognize and measure its current or deferred tax, asset or liability, applying the requirements of CPC 32 based on taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and ruling statutory tax rates, considering this uncertainty.

The Company evaluated the income tax treatments and concluded that the application of the standard did not have impacts on its results.

5 Cash and Cash Equivalents

These comprise cash on hand, deposits with banks and short-term highly-liquid investments, which can be redeemed in cash within 90 days from the investment date. Temporary short-term investments are recorded at cost at the reporting date, plus earnings accrued. Cash and cash equivalents are subject to an insignificant risk of change invalue.

Financial investments of the Company and its subsidiaries refer to Bank Deposit Certificates - CDBs and Repurchase Agreements, which are the sale of a security with the commitment of the seller (Bank) to repurchase it, and of the purchaser to resell it in the future. Investments are remunerated between 78% and 100.8% of Interbank Deposit Certificate (Certificado de Depósito Interbancário - CDI) interest.

6 Bonds and Securities

The Company and its subsidiaries have securities that yield variable interest rates. The term of these securities ranges from 1 to 59 months from the end of the reporting period.

7 Trade Accounts Receivable

7.1 Energy installments plan

The trade accounts receivable renegotiated are discounted to present value as of March 31, 2019, taking into consideration the future value, the maturity dates, the dates of settlement and the discount rate ranging from 0.07% to 4.26% p.m.

7.2 Electricity Trading Chamber - CEEE

The Company challenges in court the application filed for exclusion of responsibility in order to postpone the obligation of Colíder HPP to supply energy in connection with energy sales by the Company (Note 18.4).

Due to the success in the filing of application for preliminary injunction in the ordinary lawsuit, the Company has a receivable of R$190,856 for energy supply in the period January to October 2015, measured at the PLD amount.As the receipt of this amount is uncertain, expected credit losses in the amount of R$119,665 were recorded, corresponding to the difference between the PLD amount and the contractual amount. The remaining balance of R$71,191 corresponds to the clearly legal right receivable for the energy supply, irrespective of any litigation.

Also in relation to this lawsuit the amount of R$43,844, related to energy supply measured at the PLD amount, was not recognized due to the uncertainty on the related lawsuit merit.

7.3 Expected credit losses

8 CRC Transferred to the Paraná StateGovernment

The Company’s Management and the Paraná State Government formalized on October 31, 2017 the fifth amendment to the agreement for renegotiation of the Account for Compensation of Income and Losses - CRC. The State of Paraná complied with the agreed terms and made the payments of the monthly interest until December 2017.With the end of the grace period, the State of Paraná has strictly complied with the payments under the agreed terms, there remaining 73 monthly installments to be paid.

10.4 Remeasurement of RBSEassets

On June 27, 2017, ANEEL published Resolution 2,258 establishing the Annual Permitted Revenues (RAP) for the 2017-2018 tariff cycle, considering a court decision on the injunction of April 11, 2017 related to a lawsuit filed by three business associations, which determines the deduction of the“compensation”, provided for in article 15, paragraph 2 of Law 12,783/2013. The same decision was applied for the current 2018-2019 cycle, according to ANEEL Resolution 2,408 of June 26, 2018.

The compensation being challenged in court related to the cost of equity calculated for the RBSE assets from January 2013 to June 2017, at the time of filing of the lawsuit, is R$201,795.

Based on the opinion of its legal counsel, Copel GeT understands that this is a provisional decision and is not against Copel GeT’s right to receive the amounts related to RSBE assets, which are guaranteed by Law. Therefore, the receivables related to the compensation considered in the receipt flow of this asset are recorded in non-currentassets.

10.5 Power generation concession contract

11 Contract assets

11.1 Power distribution service concession contract

During the construction phase, the costs of borrowings and debentures are capitalized. In the first quarter of 2019, these costs totaled R$1,621 at the average rate of 0.09% p.a. (R$1,003, at the average rate of 0.06% p.a. in the first quarter of 2018, capitalized in contract assets).

This balance refers to the gas acquisition of contracted and guaranteed volumes, higher than those actually withdrawn and used, and contains a future compensation clause.

According to the contractual provisions and consumption perspectives, derived from the review of the projects and scenarios for the next years, Compagás estimates to fully offset the contracted volumes in the course of its operation. The contracts with Petrobras provide for the right to dispose of this asset. The expiration date of the concession is in discussion with the Concession Grantor, as described in Note 2.1.1.

Balance to be transferred by the CDE referring to tariff discounts on the tariffs applicable to users defined in accordance with article 13, item VII, of Law 10,438/2002 and Decree 7,891/2013. The amount transferred to Copel DIS for the period from June 2017 to May 2018, in accordance with Resolution 2,255/2017, was R$49,304 per month. As from June 2018, this amount was changed to R$62,699 per month, by Ratifying Resolution 2,402, dated 6/19/2018, which approved the result of the last Annual TariffAdjustment.

14 Prepaid Expenses

18.3 Costs of borrowings and debenturescapitalized

The costs of borrowings and debentures capitalized during the first quarter of 2019 amounted to R$1,169, at an average rate of 0.03% p.a. (R$1,297, at an average rate of 0.04% p.a. in the first quarter of 2018).

18.4 HPP Colíder

On March 9, 2019 and May 7, 2019, two generation units of the power plant started their commercial power generation operations, respectively, according to ANEEL Ordinance 673/2019 and 1,273/2019, both with installed power capacity of 100 MW. The third and last generation unit has scheduled start up of commercial power generation for the second half of 2019.

Due to acts of God and force majeure, the plant delayed the start-up of its commercial generation, initially scheduled for January 2015. Copel GeT submitted an application to ANEEL to exclude its responsibility, so that the obligation to supply energy could be postponed, which was not accepted by the agency. Copel GeT filed a common lawsuit with the Court on December 18, 2017 applying for a preliminary injunction and requesting the reversal of the decision of the Agency. On April 6, 2018, the Federal Court of the 1st Region fully granted the preliminary injunction required by Copel Get in the Interlocutory Appeal to exempt it from any burden, charges or restrictions to the right arising from the delay in the implementation schedule of the ColíderHPP.

After the beginning of partial commercial generation, in March 2019, the plant met its commitments under the power sale agreement with own generation of 41.1 MW mean, out of 125 MW mean contracted. For prior periods, Copel GeT has complied with its commitments of energy supply as follows:

· From January 2015 to May 2016 - with energy surpluses not contracted in its otherplants;

· In June 2016 - with partial reduction through a bilateral agreement;

· From July 2016 to December 2018, with reduction of all supply contracts of the CCEARs - Energy Trading Agreement in the Regulated Environment, through a bilateral agreement and participation in the New Energy and Decrease Clearing Facility (“Mecanismo de Compensação de Sobras e Déficits de Energia Nova - MCSD-EN”); and

· From January to March 2019, the firm contracts in the regulated environment became effective again, however, energy supply continued suspended in light of the injunction obtained by Management.

Since the trial on merits of the case is still outstanding, the contractual effects of both revenues and energy costs were recognized in profit or loss for the quarter for purposes of backing the outcome.

18.5 Joint operations - consortiums

The amounts recorded under property, plant and equipment referring to the share of interest of Copel GeT in consortiums are shown below:

18.5.1 Consórcio Empreendedor Baixo Iguaçu - Cebi

The Company maintains its illegitimacy to appear in the taxable position of this tax assessment, since it was not included in the judicial proceeding, thus it cannot suffer the effects of the ruling rendered thereon, which would entail its illegitimacy to appear as liable taxpayer in tax deficiency notice 6.587.156-4.

Current status:awaiting judgment.

Plaintiff: Copel Distribuição

An appeal has been brought by ANEEL, pending judgment by the TRF of the 1stRegion.

The practical outcome of the decision is that, by exempting ESBR, it exposed the distribution utilities with which it had concluded regulated power trading contracts (CCEARs), including Copel DIS, to the spot market and spot prices during the period. The reason is that electricity trading rules require that all electricity consumed be covered by a contract.

If the lawsuits are judged unfavorably against Copel, the amount will be classified as Sectorial Financial Asset to be recovered through tariffrates.

Current status:awaiting judgment.

Preliminary injunctions

As a result of preliminary injunctions in favor of the Brazilian Association of Large Industrial Consumers and Free Consumers - Abrace, and of the National Association of Energy Consumers - Anace and other associates, which challenge at court the tariff components of CDE-Use and CDE-Electricity, ANEEL, through Resolutions 1,967/2015, 1,986/2015 and 2,083/2016, ratified the tariff calculation, deducting these charges from associates of those entities, as long as the preliminary injunctions granted in Judicial Proceedings are not overthrown.

By Decree 1,576/2016, the associated distributors are assured of the right of non- transfer, deducting from the portion of CDE-Use and CDE-Electricity the amounts not collected. The unbilled amounts resulting from these injunctions do not impact the distributor's result.

The Company operates in reportable segments identified by Management, through the chief officers of each business area, taking into consideration the regulatory environments, the strategic business units and the different products and services. These segments are managed separately, since each business and each company requires different technologies and strategies.

In the first quarter of 2019, all sales have been to customers within the Brazilian territory, in addition, all non-current assets are also located in the national territory.

The Company and its subsidiaries did not identify any customer who individually accounts for more than 10% of their total net revenues in the first quarter of 2019.

36 Financial Instruments

36.1 Categories and determination of fair value of financialinstruments

Determining fair values

a) Equivalent to their respective carrying values due to their nature and terms ofrealization.

b) Fair value is calculated based on informationmadeavailable by the financial agents and the market values of the bonds issued by the Braziliangovernment

c) The criteria are disclosed in Note4.4 to the financial statements at December 31, 2018.

d) The fair values of generation assets approximate their carrying amounts, according to Note4.4 to the financial statements at December 31, 2018.

e) The fair values of assets and liabilities are equivalent to their carrying amounts according to Note 36.2.12.

f) Calculated according to the price quotations published in an active market, for assets classified as level 1 and determined in view of the comparative assessment model for assets classified as level2.

g) The cost of the last borrowing taken out by the Company is usedasa basic assumption, namely TJLP plus spread of 1.94% p.a., for discount of the expected paymentflows.

h) The Company based its calculation on the comparison with a long-term and post-fixed National Treasury Bond (NTN-B) maturing on August 15, 2024, which yields approximately 4.04% p.a. plus the IPCA inflation index.

i) Receivables related to the concession agreement for providing electricity generation services under quota arrangements at their fair value calculated by expected cash inflows discounted at therateestablished in ANEEL auction notice 12/2015(9.04%).

j) Calculated from the Unit Price quotation (PU) for March 31, 2019, obtained from the Brazilian Association of Financial and Capital Markets (ANBIMA), net of unamortized financialcost.

k) Actual net discount rate of 8.13% p.a., in line with the Company’s estimated rate for long-termprojects.

36.2 Financial risk management

The Company's business activities are exposed to the following risks arising from financial instruments:

36.2.1 Credit risk

Credit risk is the risk of the Company incurring losses due to a customer or financial instrument counterparty, resulting from failure in complying with contractual obligations.

a) The Company’s Management manages the credit risk of its assets in accordance with the Group's policy of investing virtually all of its funds in federal banking institutions. As a result of legal and/or regulatory requirements, in exceptional circumstances the Company may invest funds in prime privatebanks.

b) The risk arises from the possibility that the Company might incur losses resulting from difficulties to receive its billings to customers. This risk is closely related to internal and external factors of Copel. To mitigate this type of risk, the Company manages its accounts receivable, detecting defaulting consumers, implementing specific collection policies and suspending the supply and/or recording of energy and the provision of service, as established in theagreement.

c) Management believes this credit risk is low because repayments are secured by funds fromdividends.

d) Management believes this risk is low because these contracts assure an unconditional right to be paid in cash by the Concession Grantor at the end of the concession period for any infrastructure investments not recovered throughtariffs.

e) Management considers the risk of this credit to be reduced, since the agreements signed guarantee the unconditional right to receive cash at the end of the concession to be paid by the Concession Grantor, referring to investments in infrastructure not recovered through thetariff.

Management also considers the credit risk reduced to the balance of RBSE assets, even in light of the injunctions that temporarily reduced the RAP to be received, as described in Note 10.4.

f) Management considers the risk of this credit to be low, as the contract for the sale of energy by quota guarantees the receipt of an Annual Generation Revenue - RAG guaranteed which includes the annual amortization of this amount during the concessionterm.

g) For the generation concession assets, ANEEL published Normative Resolution 596/2013, which deals with the definition of criteria for calculating the VNR, for the purposes of indemnification. Management's expectation regarding the indemnification of these assets indicates the recoverability of the balances recorded, as described in Note 10.5.

h) This risk arises from the possibility that the Company might incur losses resulting from the volatility on the stock market. This type of risk involves external factors and has been managed through periodic assessment of the variations occurred in themarket.

36.2.2 Liquidity risk

The Company's liquidity risk consists of the possibility of having insufficient funds, cash or other financial assets to settle obligations on their scheduled maturity dates.

The Company manages liquidity risk relying on a set of methodologies, procedures and instruments applied to secure ongoing control over financial processes to ensure proper management of risks.

Investments are financed by incurring medium and long-term debt with financial institutions and capital markets.

Short, medium and long-term business projections are made and submitted to Management bodies for evaluation. The budget for the next fiscal year is annually approved.

Medium and long-term business projections cover monthly periods over the next five years. Short-term projections consider daily periods covering only the next 90 days.

The Company permanently monitors the volume of funds to be settled by controlling cash flows to reduce funding costs, the risk involved in the renewal of loan agreements and compliance with the financial investment policy, while concurrently keeping minimum cash levels.

The following table shows the expected undiscounted settlement amounts in each time range. Projections were based on financial indicators linked to the related financial instruments and forecast according to average market expectations as disclosed in the Central Bank of Brazil's Focus Report, which provides the average expectations of market analysts for these indicators for the current year and the following year. As from 2022, 2021 indicators are repeated on an unaltered basis throughout the forecast period.

As disclosed in Notes 22.5 and 23.3, the Company and its subsidiaries have borrowings agreements and debentures with covenants that if breached may have their payment accelerated.

At March 31, 2019, the Company recorded negative net working capital of R$741,834 (R$265,568 at December 31, 2018) in the Parent company and R$86,075 (R$17,268 at December 31, 2018) in the Consolidated. Management has been monitoring the liquidity and taking actions to balance the short-term financial capacity, preserving the Company's investment programs, as well as seeking debt repayment extension. An example of this borrowing is presented in Note 41.3.

36.2.3 Market risk

Market risk is the risk that the fair value or the future cash flows of a financial instrument shall oscillate due to changes in market prices, such as currency rates, interest rates and stock price. The purpose of managing this risk is to control exposures within acceptable limits, while optimizing return.

a) Foreign currency risk (US Dollar)

This risk comprises the possibility of losses due to fluctuations in foreign exchange rates, which may reduce assets or increase liabilities denominated in foreign currencies.

The Company’s foreign currency indebtedness is not significant and it is not exposed to foreign exchange derivatives. The Company monitors all relevant foreign exchangerates.

The effect of the exchange rate variation resulting from the power purchase agreement with Eletrobras (Itaipu) is transferred to customers in Copel DIS's next tariffadjustment.

The exchange rate risk posed by the purchase of gas arises from the possibility of Compagás reporting losses on the fluctuations in foreign exchange rates, increasing the amount in Reais of the accounts payable related to the gas acquired from Petrobras. This risk is mitigated by the monitoring and transfer of the price fluctuation through tariff, when possible. Compagás monitors these fluctuations on an ongoing basis.

Sensitivity analysis of foreign currency risk

The Company has developed a sensitivity analysis in order to measure the impact of the devaluation of the US dollar on its borrowings subject to currency risk.

The baseline scenario takes into account the existing balances in each account as of March 31, 2019and the probable scenario assumes a variation in the foreign exchange rate – prevailing at the end of the period (R$/USD 3.75) based on the median market expectation for 2019 reported in the CentralBank’sFocus report of April 26, 2019. For the scenarios 1 and 2, deteriorations of 25% and 50%, respectively, were considered for the main risk factor for the financial instrument compared to the rate used in the probable scenario.

In addition to the sensitivity analysis required by CVM Resolution 475/2008, the Company evaluates its financial instruments considering the possible effects on profit and loss and equity of the risks evaluated by the Company’s Management on the reporting date for the financial instruments, as recommended by CPC 40 (R1) - Financial Instruments: Disclosure. Based on the equity position and the notional value of the financial instruments held as of March 31, 2019, it is estimated that these effects will approximate the amounts stated in the above table in the column for the forecast probable scenario, since the assumptions used by the Company are similar to those previouslydescribed.

b) Interest rate and monetary variation risk

This risk comprises the possibility of losses due to fluctuations in interest rates or other indicators, which may reduce financial income or financial expenses or increase the financial expenses related to the assets and liabilities raised in the market.

The Company has developed a sensitivity analysis in order to measure the impact of variable interest rates and monetary variations on its financial assets and liabilities subject to these risks.

Sensitivity analysis of interest rate and monetary variation risk

The Company has developed a sensitivity analysis in order to measure the impact of variable interest rates and monetary variations on its financial assets and liabilities subject to these risks.

The baseline scenario takes into account the existing balances in each account as of March 31, 2019 while the ‘probable’ scenario assumes balances reflecting varying indicators as follows: CDI/Selic - 6.50%, IPCA – 4.01%, IGP-DI – 5.83%, IGP-M – 5.58% and TLP - 6.10%, estimated as market average projections for 2019 according to the Focus Report issued by the Central Bank of Brazil asof April 26, 2019, except TLP that considers the Company’s internalprojection.

For the scenarios 1 and 2, deteriorations of 25% and 50%, respectively, were considered for the main risk factor for the financial instrument compared to the rate used in the probable scenario.

In addition to the sensitivity analysis required by CVM Resolution 475/2008, the Company evaluates its financial instruments considering the possible effects on profit and loss and equity of the risks evaluated by the Company’s Management on the reporting date for the financial instruments, as recommended by CPC 40(R1). Based on the equity position and the notional value of the financial instruments held as of March 31, 2019, it is estimated that these effects will approximate the amounts stated in the above table in the column for the forecast probable scenario, since the assumptions used by the Company are similar to those previouslydescribed.

36.2.4 Electricity shortage risk

Approximately 64% of installed capacity in Brazil currently comes from hydroelectric generation, as informed by the Generation Information Bank of ANEEL, which makes Brazil and the geographic region in which we operate subject to hydrological conditions that are unpredictable, due to non-cyclical deviations of mean precipitation. Unsatisfactory hydrological conditions may cause, among other things, the implementation of comprehensive programs of electricity savings, such as rationalization or even a mandatory reduction of consumption, which is the case of rationing.

Since 2014, the reservoirs of the Southeast/Midwest, North and Northeast Brazilian regions have been subject to adverse climate situations, leading agencies responsible for this industry to adopt water resources optimization measures to guarantee fully meeting electricitydemand.

The Electric Sector Monitoring Committee (CMSE) has maintained the energy deficit risk indicators within the safety margin in short-term projections. The same position is adopted by ONS regarding the risk of deficit in the medium term, as stated in the 2018-2022 Energy OperationPlan – PEN 2018.

Although dam storage levels are not ideal, from the standpoint of regulatory agencies, when combined with other variables, they are sufficient to keep the risk of deficit within the safety margin established by the National Energy Policy Council - CNPE (maximum risk of 5%) in all subsystems.

36.2.5 Risk of GSF impacts

The Energy Reallocation Mechanism (MRE) is a system of redistribution of electricpowergenerated, characteristic of the Brazilian electric sector, which has its existence by the understanding, at the time, of the need for a centralized operation associated with a centrally calculated optimal price known as PLD. Since generators have no control over their production, each plant receives a certain amount of virtual energy which can be compromised through contracts. This value, which enables the registration of bilateral contracts, is known as Physical Guarantee - GF and is also calculated centrally. Unlike PLD, which is calculated on a weekly basis, GF, as required by Law, is recalculated every five years, with a limit of increase or decrease, restricted to 5% by revision or 10% in the concessionperiod.

The contracts need to have an energy physical guarantee basis. This is done, especially, through the allocation of power generated received from the MRE or purchase. The GSF is the ratio of the entire hydroelectric generation of the MRE participants to the GF sum of all the MRE plants. Basically, the GSF is used to calculate how much each plant will receive from generation to back up its GF. Thus, knowing the GSF of a given month the company will be able to know if it will need to back up its contracts through purchases.

Whenever GSF multiplied by GF is less than the sum of contracts, the company will need to buy the difference in the spot market. However, whenever GSF multiplied by GF is greater than the total contracts, the company will receive the difference to the PLD.

The low inflows that have been recorded since 2014, as well as problems with delays in the expansion of the transmission system have resulted in low GSF values, resulting in heavy losses for the companies holding MRE participating hydroelectric projects.

For plants with contracts in the Free Contracting Environment - ACL, the main way to manage the low GSF risk is not to compromise the entire GF with contracts, approach currently adopted by the Company.

For the contracts in the ACR, Law 13,203/2015 allowed the generators to contract insurance for electricity demand (load), by means of payment of a risk premium. Copel adopted this approach to protect contracts related to energy generated by the Mauá, Santa Clara, Fundão, Baixo Iguaçu and Colíder Thermoelectric Plants and Cavernoso II Small HPP.

For the distribution segment, the effects of the GSF are perceived in the costs associated with quotas of Itaipu, of Angra and the plants whose concessions were renewed in accordance with Law 12,783/2013, as well as in the costs of the contracts for power availability with thermoelectric plants. This is a financial risk, since there is guarantee of neutrality of expenses with energy purchases through a tariff transfer.

36.2.6 Risk of non-renewal of concessions - generation andtransmission

Currently, the extension of generation, transmission and distribution concessions covered by Articles 17, 19 and 22 and Law 9,074/1995, is regulated by Law 12,783/2013. Decree 9,187 of November 1, 2017 regulates the extension of the thermoelectric power generation concessions set forth in said Law.

Concessions of hydroelectric power generation, electric power transmission and distribution may be extended at the discretion of the Concession Grantor, one single time, for a period of up to 30 years. However, for concessions of thermoelectric power generation, extension period is limited to 20 years.

The concession operator should request extension of concession at least 60 months before the final contract date or after granting of concessions to hydroelectric power generation and electric power transmission and distribution plants, and of up to 24 months for thermoelectric plants. The Concession Grantor may advance effects of extension by up to 60 months counted as of contract or grant date, and may also define initial tariff or revenue.

By 2023, only Governor Bento Munhoz da Rocha Netto hydroelectric power plant (1676 MW) will have its concession expired. The Company did not express an interest in extending this concession. Under Law 12,783/2013, the option for extension is conditioned to a change in the plant operation regime, which may occur within 60 months before its final term. Internal studies have shown that the extension through change of the anticipated operation regime is economically and financially disadvantageous in relation to the exploration of the plant in the present regime until its final term. The plant must be tendered by the Concession Grantor and the Company may participate in the auction, if it meets the qualification conditions.

Regarding the Figueira HPP concession, expired in March 2019, the Company awaits the conclusion of the related ANEEL procedural steps to execute the Amendment to the Concession Agreement. The plant is undergoing a modernization process and will have as direct benefits the improvement in energy efficiency and the reduction of pollutant emissions in the atmosphere, in comparison with the old plant.

According to the law, the Company may express its intention to extend the concession of the São Jorge HPP in 2019, the Apucaraninha HPP in 2020, and the Guaricana and Chaminé HPPs in 2021. If the Company does not express an interest in the extension of the current regime, the concession of the São Jorge HPP may, at its final term, be granted to the Company in the condition of registration, and the other concessions, at their final term, shall be tendered by the Concession Grantor.

Copel GeT does not have any transmission concession ending in the next ten years.

36.2.7 Risk on non-renewal of concessions - distribution of electricity

On December 9, 2015, pursuant to the fifth Concession Agreement Amendment No. 46/1999 of Copel DIS, the concession was extended, provided that quality and efficiency parameters for provision of distribution services are met, measured by indicators that consider duration and frequency of service interruptions (DECi and FECi) and efficiency in the Company’s economic and financial management.

The fifth amendment to the concession agreement imposes indexes of economic and financial efficiency and quality. Failure to comply with the indexes for two consecutive years or any limits at the end of the first five years will result in the termination of the concession (clause 18, sub clause 1), observing the agreement terms, specifically the right to full defense and reconsideration.

Non-compliance with the annual global electricity supply quality indicators (DEC and FEC) for two consecutive years or three times in five years, depending on ANEEL’s regulation, may limit the payment of dividends or interest on capital (clause 2, sub clause 8), while the breach of the economic and financial sustainability indicators may require a capital contribution from the controlling shareholders (clause 13, sub clause 4) within up to180 days from the end of each fiscal year, of the total insufficient amount to meet the Minimum Economic and Financial Sustainability Parameter provided for in clause 7.

From the sixth year following the signing of the agreement, the breach of quality criteria for three consecutive years or of economic and financial management criteria for two consecutive years will result in the opening of an expiration proceeding (clause 12, sub clause 14), causing the end of the concession.

The following table sets forth the minimum parameters of economic and financial sustainability defined for Copel DIS in the first five years of the renewal:

36.2.8 Risk of non-extension of the gas distributionconcession

As presented in Note 2.1.1, the expiration date of the gas distribution concession of the subsidiary Compagás is under discussion with the concession grantor.

In the event of non-extension of the concession, Compagás will be entitled to compensation for investments made in the last 10 years prior to the end of the concession at their depreciated replacement value, according to the contractualclause.

36.2.9 Risk of overcontracting and undercontracting ofelectricity

Under the current regulatory model, the agreement for purchase of electric power by distributors is regulated by Law 10,484/2014 and Decree 5,163/2004, which determine that distributors must purchase the volume required to serve 100% of their market.

The contracting of the total output available in the market is verified by observing the period comprising the calendar year, and the difference between the costs remunerated by the tariff and those actually incurred in the power purchases are fully passed on to captive consumers, as long as the Distributor presents a contracting level between 100% and 105% of its market. However, if distributors determine contracting levels lower or higher than the regulatory limits, there is the assurance of neutrality if it is identified that such violation derives from extraordinary and unforeseen events that are not manageable by the buyer.

Since 2016, the distribution segment has been exposed to a general overcontracting scenario, as most companies determined contracting levels higher than 105%. Considering that several factors that have contributed to this situation are extraordinary and unavoidable by the distributors, such as the involuntary allocation of physical guarantee quotas and the broad migration of consumers to the free market, ANEEL and MME implemented a series of measures aiming at the mitigation of overcontracting.

In relation to the contracting of 2019, the scenarios of supply and demand indicate the possibility of occurrence of overcontracting due to consumers migration to the free market. This is the main risk factor involving exposure to overcontracting, which entitles recognition of involuntary overcontracting.

36.2.10 Gas shortage risk

This risk involves potential periods of shortage of natural gas supply to meet the Company’s gas distribution and thermal generation business requirements. Long periods of gas shortage could result in losses due to lower revenues by subsidiaries Compagás and UEG Araucária.

The natural gas supply contract between Brazil and Bolivia is effective for twenty years, ending in 2019. Due to the non-use of all contracted natural gas in recent years, the Ministry of Mines and Energy considers the extension of the term of this contract by two years in its Ten Year Planning. In the event of non-renewal of this contract, currently centralized in Petrobras, direct consumers or state distributors must directly negotiate the fuel supply with producers, importers or suppliers of natural gas.

On the other hand, the volume of natural gas produced in the pre-salt has increased. The Brazilian’s output in 2018 was 111.94 million m³/day and with growing trend.

In addition to the gas from Bolivia and from the pre-salt, there is the alternative of importing Liquified Natural Gas (LNG).

There are also projects of new regasification stations in all Brazilian regions, with stations located in the South region of Brazil capable of serving the consumption of this region of the country without the need for large investments in transport infrastructure and reducing the level of capacity utilization of the Gasbol Sul line, which would increase the supply of natural gas in Paraná.

In the international market, the natural gas price has remained stable, indicating a balance between supply and demand.

In this scenario, the natural gas shortage risk can be considered low.

36.2.11 Risk of non-performance of wind farms

The power generation authorization contracts for wind power are subject to performance clauses, which provide for a minimum annual and four-year generation of the physical guarantee committed in the auction. Ventures are subject to climatic factors associated with wind velocity uncertainties, and non-compliance with what is stated in the agreement may jeopardize future revenues of the Company. At March 31, 2019, the consolidated balance of the provision recorded in liabilities referring to the non-performance is R$61,399 (R$83,525 at December 31, 2018), which may be offset by higher future production, measured within the annual and/or four-yearly contractual cycle.

36.2.12 Risk related to price of power purchase and sale transactions in the activemarket

The Company operates in the market for the purchase and sale of energy in the active market (Note 4.15 to the financial statements at December 31, 2018), with the objective of achieving results with changes in energy prices, subject to the risk limits established by Management. This activity, therefore, exposes the Company to the risk of future energy price.

The purchase and sale of energy are recognized at fair value through profit or loss, based on the difference between the contracted price and the market price of the transactions at the balance sheet date.

Based on the notional value of R$232,911 for purchase contracts and R$142,838 for contracts for the sale of electricity, outstanding on March 31, 2019, the fair value was estimated using the prices defined by the Company in the last week of March 2019, which represented the best estimate of the future market price. The discount rate uses the return rate of the NTN-B disclosed by ANBIMA as of March 29, 2019, adjusted by a credit risk rate.

The balances relating to these outstanding transactions at March 31, 2019 are presented below:

Sensitivity analysis on the power purchase and sale transactions in the active market

The main risk factor is the exposure to variation of energy market prices. The variation of the discount rate does not have a relevant impact on the fair value determined, especially in view of the short-term for the settlement of contracts.

The sensitivity analyses were prepared in accordance with CVM Instruction 475/08, considering, for scenarios 1 and 2, the increase or decrease of 25% and 50% in future prices, applied to market prices of March 31, 2019. The results obtained are as follows:

36.2.13 Counterparty risk in the energy market

Since free energy market still does not have a counterparty acting as guarantor of all agreements (clearing house), there is a bilateral risk of default. Thus, the Company is exposed to the risk of failure in the supply of energy contracted by the seller. In the event of such failure, the Company must buy energy at the spot market price, being further subject to regulatory penalties and loss of amounts paid.

The Company follows a policy that establishes limits for possible operations with each counterparty, after analyzing its credit worthiness, maturity and history.

In addition, even if our policy is more restrictive, and the counterparties present good financial condition, the Company is exposed to systemic events in which the default of one agent ends up affecting other energy trading companies in a "domino effect" until reaching the Company's counterparties.

36.3 Capital management

The Company seeks to keep a strong capital base to maintain the trust of investors, creditors and market and ensure the future development of the business. Management also strives to maintain a balance between the highest possible returns with more adequate levels of borrowings and the advantages and the assurance afforded by a healthy capital position. Thus, it maximizes the return for all stakeholders in its operations, optimizing the balance of debts and equity.

The Company monitors capital by using an index represented by adjusted consolidated net debt divided by adjusted consolidated EBITDA (Earnings before interest, taxes, depreciation and amortization), for the last twelve months. The corporate goal established in the strategic planning provides for maintenance of ratio below 3.5 while any expectation of failing to meet this target will prompt Management to take steps to correct its course by the end of each reporting period.

36.3.1 The equity to debt ratio is shown below:

37 Related Party Transactions

COMMENTS ON PERFORMANCE /

for the quarters ended March 31, 2019 and 2018

All amounts expressed in thousands of Brazilian reais

1 Distribution Lines

Compact-Design Distribution Lines –Copel Distribuição S.A. has implemented compact-design distribution lines in urban areas with a high concentration of trees surrounding distribution grids. This technology reduces the number of trees cut down or trimmed and improves the quality of power supply by reducing the number of unplanned outages. The total length of compact-design distribution lines installed at the end of March 2019 was 10,671km (9,778 km in March 2018), up by 893 km year-over-year, a variation of 9.1%.

Secondary Isolated Lines –Copel Distribuição is also investing in low-voltage (127/220V) secondary isolated lines, which offer substantial advantages over regular overhead lines, including: improvement in DEC - Equivalent Time of Interruption per Consumer Unit and FEC - Equivalent Frequency of Interruption per Consumer Unit distribution performance indicators; defense against illegal connections; improved environmental conditions; reduced areas subject to tree trimming; improved safety; reduced voltage drops throughout the grid; and increased transformer useful life due to the reduction of short-circuits, among other advantages. The total length of secondary isolated lines as of the end of March 2019 was 18,435 km (against 17,603 km in March 2018), up by 832 km year-over-year, a variation of 4.7%.

2 Power Market

Market behavior -Power generation by Copel Geração e Transmissão S.A. and wind farms totaled 4,825 GWh in the first three months of 2019 (against 5,799 GWh in the same period in 2018). The volume of energy purchased by Copel Distribuição by means of CCEARs (auctions) was 3,068 GWh (against 2,674 GWh in the same period in 2018), while the volume purchased from Itaipu was 1,375 GWh (against 1,413 GWh in the same period in 2018), as described below:

Energy sale -The table below sets out Copel’s total energy sales, broken down among Copel Distribuição, Copel Geração e Transmissão, Copel Comercialização and wind farms:

Captive Market of Copel Distribuição - Energy sales to Copel Distribuição’s captive market totaled 5,246 GWh in the first three months of 2019, up by 4.7% against the same period in 2018. This result was mainly influenced by the increase in the consumption of the residential and commercial segments, in particular by the high temperatures in January, with average variation above 10%, in addition to more business days in February.

The residential segment consumed 1,998 GWh from January to March 2019, up by 8.1% caused by (i) the increase in average monthly energy consumption (176 kWh/month in 1Q19 compared to 166 kWh/month in 1Q18), mainly due to maximum temperatures recorded in January, which surpassed the historical average in several regions of the Paraná State, leading to an increase in the use of fans and air conditioners; and (ii) the increase of 1.9% in the number of clients. In the first quarter of 2019, the consumption of the residential segment was equivalent to 38.1% of the captive market, totaling 3,772,134 consumers.

The consumption of the industrial segment decreased by 7.3% in the first quarter of 2019, to 658 GWh, mainly caused by the migration of captive clients to the free market, which would represent an average consumption of approximately 82 GWh in the quarter. By the end of March 2019, the industrial segment represented 12.5% of the captive market’s consumption with 72,510 consumers.

The commercial segment consumed 1,298 Gwh in the first quarter of 2019, up by 6.9% compared to the same period in 2018. This result was due to the good performance of the retail trade in the Paraná State – growth of 3.3% and 4.4 % in January and February, respectively, compared to the same months in 2018 - and the increase in the client base recorded at the end of March 2019. At the end of this quarter, this segment represented 24.7% of the captive market with 401,293 consumers.

The rural segment recorded a 5.2% increase in energy consumption in the first quarter of 2019, totaling 665 GWh. By the end of March 2019, the segment accounted for 12.7% of the Copel’s captive market, totaling 351,663 consumers.

The consumption of other segments (public bodies, public lighting, public services and own consumption) totaled 627GWh from January to March 2019, with an increase of 3.6%. Jointly, these segments accounted for 12.0% of the captive market, totaling 57,762 consumers at the end of March 2019.

Number of consumers –The number of end consumers (captive consumers of Copel Distribuição and free consumers of Copel GeT, Copel Comercialização and other suppliers within the concession area of Copel Distribuição) billed in March 2019 was 4,656,533, up by 1.7% against the same month in 2018.

a) 23.7% increase in Revenues from Electricity Sales to Final Customers, mainly caused by the 6.8% increase in the volume of energy sold to end consumers – mainly the 4.7% increase in consumption of the captive market of Copel DIS and 11.2% increase in consumption of the industrial free market of Copel GeT and Copel Comercialização – as well as the tariff adjustment of Copel DIS by 15.61%, effective June 24, 2018;

b) 6.9% increase in Revenues from Electricity Sales to Distributors, mainly caused by the increase in sales through regulated environment contracts, due to the start of operation of new projects;

c) 37.0% increase in Revenues from the Use of Main Distribution and Transmission Grid, mainly caused by the adjustment by 16.41% in June 2018 (0.85% in June 2017) and the recovery of the wire market by 5.1% in the period;

d) 19.4% increase in Revenues from Telecommunications, chiefly due to the increase in the number of clients, particularly in the retail market with the Copel Fibra product; and

e) 46.2% increase in Revenues from Distribution of Piped Gas impacted by the increase in gas sales due to the increase in the gas volume consumed, as well as a tariff adjustment by 16% compared to prior year;

f) 133.2% decrease in Sectorial Financial Assets and Liabilities, mainly caused by the amortization of the amounts considered in the 2018 adjustment and a slight variation in the balances for the 2019 adjustment; and

g) 46.5% increase in Other Operating Revenues due to the increase in revenue from services rendered and revenues from leases and rentals.

Operating Costs and Expenses (Note 33)

Operating costs and expenses totaled R$3,043,019, up by 9.2% compared to R$2,786,599 recorded in the same period in 2018. The main highlights were as follows:

a) 18.4% increase in Electricity purchased for resale, especially given the increase in energy purchases related to the trading company and the price variation in the period;

b) 27.1% decrease in Personnel and management mainly due to the provision for the voluntary employee termination program in the amount of R$91,152 recorded in 2018 and with no effects in 2019 due to the end of the program, the reduction of headcount and the cost reduction policy; partially offset by the salary adjustment, according to the collective bargaining agreement, of 3.97% in October 2018;

c) 25.7% increase in the Depreciation and amortization account due to the integration of Colíder, Cutia and Baixo Iguaçu plants, as well as higher depreciation of telecommunication assets; and

d) 11.6% decrease in the Credit losses, provisions and reversals account, mainly due lower amount of recorded labor contingencies compared to the same period in the prior year.

Financial Results (Note 34)

The variation of R$28,546 in financial results, corresponding to 41.0% compared to the same period in 2018, is mainly due to a 10.8% increase in financial expenses, due to higher monetary and exchange variations and debt charges.

EBITDA

EBITDA (earnings before interest, taxes, depreciation and amortization) is as follows:

The EBITDA is a non-accounting measure prepared by the Company, reconciled with its financial statements, in accordance with the provisions of Circular Letter/CVM/SNC/SEP 01/2007 and CVM Instruction 527/2012. It is not a measure recognized by accounting practices adopted in Brazil or international accounting standards, does not have a standard meaning and cannot be comparable to measures with similar titles provided by other companies. The Company discloses it because it is used to measure its performance.

The EBITDA cannot be considered separately or as a substitute of net income or operating income, as an indicator of operating performance or cash flow, or to measure the liquidity or the ability to pay debt.

RELATÓRIO DO AUDITOR INDEPENDENTE

REPORT ON REVIEW OF INTERIM FINANCIAL INFORMATION

To the Shareholders and Management of

Companhia Paranaense de Energia – COPEL

Curitiba - PR

Introduction

We have reviewed the accompanying individual and consolidated interim financial information of Companhia Paranaense de Energia - COPEL (the “Company”), included in the Quarterly Information Form - ITR for the quarter ended March 31, 2019, which comprises the statement of financial position as at March 31, 2019 and the related statements of income, of comprehensive income, of changes in equity and of cash flows for the three-month period then ended, including the explanatory notes.

The Company’s Management is responsible for the preparation of this individual and consolidated interim financial information in accordance with technical pronouncement CPC 21 (R1) – Interim Financial Reporting and with international standard IAS 34– Interim Financial Reporting issued by the International Accounting Standards Board – IASB, as well as for the presentation of such information in accordance with the standards issued by the Brazilian Securities and Exchange Commission - CVM, applicable to the preparation of Quarterly Information - ITR. Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on review of interim financial information (NBC TR 2410 and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the standards on auditing and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the individual and consolidated interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the Quarterly Information - ITR referred to above has not been prepared, in all material respects, in accordance with technical pronouncement CPC 21 (R1) and international standard IAS 34 applicable to the preparation of Quarterly Information - ITR and presented in accordance with the standards issued by the Brazilian Securities and Exchange Commission - CVM.

Emphasis of matter

Restatement of the financial information at March 31, 2018

On May 15, 2018, we issued an unmodified report on review of the Company’s interim financial information, which is now being restated. As described in note 3.6, the interim financial information at March 31, 2018 has been adjusted and is being restated as set out in CPC 23 – Accounting Policies, Changes in Accounting Estimates and Errors and CPC 26(R1) – Presentation of Financial Statements to reflect the effects from application of CPC 47 – Revenue from Contracts with Customers, in joint ventures, in calculating equity in earnings of investees. Our conclusion is not modified in respect of this matter.

Other matters

Statements of value added

We have also reviewed the individual and consolidated statements of value added (“DVA”) for the three-month period ended March 31, 2019, prepared under the responsibility of the Company’s Management, the presentation of which in the interim financial information is required by the standards issued by the CVM applicable to the preparation of Quarterly Information – ITR, and considered supplemental information by International Financial Reporting Standards - IFRS, issued by the IASB, which do not require the presentation of a DVA. These statements were subject to the same review procedures previously described and, based on our review, nothing has come to our attention that causes us to believe that they have not been prepared, in all material respects, in relation to the interim financial information taken as a whole.
