( 2 ) PRESENTATION OF THE INTERIM FINANCIAL STATEMENTS

2.1 Basis of preparation

This interim individual (Parent Company) and consolidated financial statement has been prepared and is being presented in accordance with the International Accounting Standard IAS 34 - Interim Financial Reporting, issued by the International Accounting Standard Board – IASB, and also based on standards issued by the Brazilian Securities and Exchange Commission (CVM), applicable to the preparation of Quarterly Financial Information (ITR), in accordance with Technical Pronouncement CPC 21 (R1) - Interim Financial Reporting.

The Company and the subsidiaries (“Group”) also follows the guidelines of the Accounting Manual of the Brazilian Electricity Sector and the standards laid down by the Brazilian Electricity Regulatory Agency (Agência Nacional de Energia Elétrica – ANEEL), when these do not conflict with the accounting practices adopted in Brazil and/or International Financial Reporting Standards.

The accounting practices and criteria adopted in preparing these individual and consolidated interim financial statements are consistent with those adopted in preparing the financial statements at December 31, 2018, except for IFRS 16 and IFRIC 23 that, as described in note 3.18 of those financial statements, had no material impact, and therefore should be read together.

Management states that all material information of the interim financial statements is disclosed and corresponds to what is used in the Group's management.

The interim financial statements were authorized for issue by Management and on May 6, 2019.

2.2 Basis of measurement

The interim financial statements has been prepared on the historical cost basis except for the following items recorded in the statements of financial position: i) derivative financial instruments measured at fair value and ii) non derivative financial instruments measured at fair value through profit or loss. The classification of the fair value measurement in the level 1, 2 or 3 categories (depending on the degree of observance of the variables used) is presented in note 33 – Financial Instruments.

2.3 Use of estimates and judgments

The preparation of the interim financial statements requires the Group’s management to make judgments, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income and expenses.

By definition, the accounting estimates are rarely the same as the actual results. Accordingly, the Group’s management review the estimates and assumptions on an ongoing basis, based on previous experience and other relevant factors. Adjustments resulting from revisions to accounting estimates are recognized in the period in which the estimates are revised and applied on a prospective basis.

The main accounts that require the adoption of estimates and assumptions, which are subject to a greater degree of uncertainty and may result in a material adjustment if these estimates and assumptions suffer significant changes in subsequent periods, are:

2.7 Statement of value added

The Company has prepared the individual and consolidated statements of value added (“DVA”) in conformity with technical pronouncement CPC 09 - Statement of Value Added, which are presented as an integral part of the interim financial statements in accordance with accounting practices adopted in Brazil and as supplementary information to the interim financial statements in accordance with IFRS, as this statement is neither provided for nor required by IFRS.

2.8 New presentation of financial statements of 2018 – breakdown of lines

Starting in 2019, focusing on improving the presentation of the financial statements for the monitoring of results by Group Management, through a better analysis of costs and expenses accounts, the Company split the depreciation, amortization and allowance for doubtful accounts lines in the income statement.

For comparability purposes, these changes were applied retrospectively according to CPC 23/IAS 8, and therefore, the interim financial statements regarding 2018 are being restated with the same breakdown. There are no changes in costs and expenses assumptions.

The following table summarizes the impacts on interim financial statements:

( 3 ) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Except for the changes noted bellow these interim financial information of the Group was prepared based on the same accounting policies described in notes 3.1 to 3.18 disclosed in the financial statements for the year ended December 31, 2018. Effects of the changes in accounting policies on the group's consolidated financial statements for the year ended December 31, 2019 are also expected.

Nature and effect of the changes arising from the application of the new and revised standards

The Group initially adopted CPC 06(R2) / IFRS 16 Leases and ICPC 22 / IFRIC 23 Uncertainty over Income Tax Treatments as of January 1, 2019. A series of other new standards are effective as of January 1, 2019, without material effect on the Group’s interim accounting information.

With respect to ICPC 22 / IFRIC 23, the Group applied the interpretation and informs that there was no material impact on its adoption.

The CPC 06 (R2) / IFRS 16 sets out the principles for the recognition, measurement, presentation and disclosure of leases, from the lessees and lessors’ perspectives. Among the changes arising from IFRS 16, this standard eliminated the classification of leases as either operating leases or finance, providing for a single lessee accounting model in which all leases result in the recognition of a right-of-use asset and a lease liability.

Following the adoption of CPC 06 (R2) / IFRS 16, lease payments under operating leases are not charged to operating results on accrual basis. Instead, depreciation of the right to use a leased asset, as well as the finance expenses and foreign exchange gains or losses over the lease liability, affect the results. As regards the lessors, it virtually retains the requirements of IAS 17, including only some additional disclosure aspects.The Company applied short-term lease exemption and recognizes payments associated with such leases as expenses over the arrangements terms.

According to the transition provisions set forth in CPC 06 (R2) / IFRS 16, the Company applied this standard retrospectively with the cumulative effect of its initial application recognized at January 1. 2019, without restatement of prior period information, and the following practical expedients were chosen: short-term leases (contracts with maximum duration of 12 months) and low-value items (fair value of the identified leased asset lower than US$ 5 thousand). The lessor accounting remained similar to the current standard – i.e. lessors continue to classify leases as finance or operating leases.

The standard defines that a contract is or contains a lease if it conveys the right to control the use of the identified assets for a period of time for a consideration. As a result of the initial application of IFRS 16, in regard to leases that were previously classified as operating leases, the Group assessed the standard and concluded that there was no material impact on its adoption.

( 4 ) FAIR VALUE MEASUREMENT

A number of the Group’s accounting policies and disclosures require the fair value measurement, for both financial and non-financial assets and liabilities. Fair values have been determined for measurement and / or disclosure purposes based on the following methods. When applicable, additional information on the assumptions made in the fair value measurement is disclosed in the notes specific to that asset or liability.

The Group measures fair value as the price that would be received for the sale of the asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

- Property, plant and equipment, intangible assets and contract asset

The fair value of items of property, plant and equipment is based on the market approach and cost approaches using quoted market prices for similar items when available and replacement cost when appropriate.

- Financial instruments

Financial instruments measured at fair value are valued based on quoted prices in an active market, or, if such prices are not available, they are assessed using pricing models, applied individually to each transaction, taking into consideration future cash flows, based on the contractual conditions, discounted to present value at rates obtained from market interest curves, having as a basis, whenever available,information obtained from the websites of B3 S.A. and “Associação Brasileira das Entidades dos Mercados Financeiro e de Capitais – ANBIMA” (note 33) and also includes the debtor's credit risk rate.

Interim Standard Financial Statements – ITR – Date: March 31, 2019 - CPFL Energia S.A.

The right to compensation, to be paid by the Federal Government when the distribution concessionaires’ assets are handed over at the end of the concession period are classified as measured at fair value through profit or loss. The methodology adopted for valuing these assets is based on the tariff review process for distributors. This process, conducted every four or five years according to each concessionaire, involves assessing the replacement price of the distribution infrastructure, in accordance with criteria established by the granting authority (“ANEEL”). This valuation basis is also used for establishing the distribution tariff, which is adjusted annually up to the next tariff review, based on main inflation indices.

Accordingly, at the time of the tariff review, each distribution concessionaire adjusts the position of the financial asset base for compensation at the amounts ratified by the granting authority and uses the Extended Consumer Price Index (“IPCA”) as the best estimates for adjusting the original value until the next tariff review process.

Exclusion of ICMS from the PIS and COFINS tax base

A number of subsidiaries of the Group are parties to several pending legal proceedings involving the Brazilian federal government that address the exclusion of ICMS amounts from the PIS and COFINS tax base, as well as the Group subsidiaries’ rights to receive refunds of other amounts previously paid. In the quarter ended March 31, 2019, CPFL Santa Cruz (related to the original lawsuit presented by four merged companies - CPFL Leste Paulista, CPFL Sul Paulista. CPFL Jaguari and CPFL Mococa) received a favorable final judicial decision on these matters, which is not subject to further appeal . As a result, CPFL Santa Cruz recognized a tax credit of R$ 166,870 using the calculation method in accordance with the “Federal Revenue Orientation 13/2018”. Based on advice of external legal counsel, the Group understands that amounts received by its distribution subsidiaries as tax credits will need to be refunded to consumers as soon the Brazilian Federal Revenue approves such tax credits as compensation payable to affected consumers. The Group is still discussing with its external legal advisors the relevant time period applicable to calculating the refunds of tax credits to consumers, which may be for a period of three, five or ten years . On March, 31 2019, CPFL Santa Cruz recognized a liability related to tax credits that need to be refunded to the relevant consumers for the maximum period of 10 years.

As a result, for the quarter ended March 31, 2019, CPFL Santa Cruz recognized a debit of R$ 166,870 as “Taxes Recoverable”, against R$ 132,374 of credit in “Other Payable – Consumers” and a credit of R$ 34,495 as “Deduction from operating revenues – PIS and COFINS”. No other amounts have been recognized as the other Group subsidiaries await final decisions in their respective legal proceedings.

The amount refers to the financial asset corresponding to the right established in the concession agreements of the energy distributors to receive cash by compensation upon the return of the assets to the granting authority at the end of the concession, measured at fair value.

According to the current tariff model, the remuneration for this asset is recognized in profit or loss upon billing to consumers and the realization occurs upon receipt of the electric energy bills. Moreover, the difference to adjust the balance at fair value (new replacement value) is recognized as a balancing item to the operating income account (note 26) in the statement of profit or loss for the period (R$ 67,264 for the quarter ended March 31, 2019 and R$ 66,637 for the quarter ended March 31, 2018).

Interim Standard Financial Statements – ITR – Date: March 31, 2019 - CPFL Energia S.A.

As segregated in the tables above, in conformity with CPC 48 and IFRS 9, the Group classified their debts as (i) financial liabilities measured at amortized cost, and (ii) financial liabilities measured at fair value through profit or loss.

The objective of the classification as financial liabilities of borrowings measured at fair value is to reduce the effects of the recognition of gains and losses derived from fair valuing debt-related derivatives in order to obtain more relevant and consistent accounting information, reducing the accounting mismatch. At March 31, 2019, the balance of the borrowings measured at fair value was R$ 5,292,261 (R$ 5,631,255 at December 31, 2018).

Changes in the fair values of these borrowings are recognized in the finance income / expense of the Group, except for the changes in fair value due to credit risk, which is recognized in other comprehensive income. At March 31, 2019, the accumulated gains of R$ 95,671 (R$ 103,351 at December 31, 2018) on measuring of the borrowings to fair value, offset by the losses of R$ 56,275 (R$ 65,678 at December 31, 2018) of fair value measurement of the derivative financial instruments contracted as a hedge against foreign exchange variations (note 33), resulted in a total net gain of R$ 39,396 (R$ 37,673 at December 31, 2018).

The maturities of the principal of borrowings recorded in noncurrent liabilities are scheduled as follows:

Maturity		Consolidated
From April 1st, 2020		1,379,993

(*) In accordance with CPC 48/IFRS 9 this refers to borrowing costs directly attributable to the issuance of the respective debts.

As shown in the table above, the Company classifies its debentures as (i) financial liabilities measured at amortized cost; and (ii) financial liabilities measured at fair value through profit or loss.

The classification of debentures measured at fair value as financial liabilities is aimed at reducing the accounting mismatching of the effects of the recognition of gains and losses derived from the fair value measurement of hedging derivatives linked to such debentures, in order to obtain a more relevant and consistent accounting information. At March 31, 2019, the balance of debentures designated at fair value totaled R$ 437,888 (R$ 434,367 at December 31, 2018).

The changes in the fair values of these debentures are recognized in the Company’s finance income (expense), except for the fair value changes in credit risk, which is recognized in other comprehensive income. At March 31, 2019, the accumulated losses obtained from the fair value measurement of such debentures amounted to R$ 10,770 (R$ 7,378 at December 31, 2018) which, offset by the gains obtained from the fair value measurement of the derivative instruments of R$ 30,486 (R$ 21,012 at December 31, 2018), undertaken to hedge the interest rate changes (note 33), generated a total gain of R$ 19,716 (R$ 13,634 at December 31, 2018).

The maturities of the principal of debentures recognized in noncurrent liabilities are as follows:

Interim Standard Financial Statements – ITR – Date: March 31, 2019 - CPFL Energia S.A.

(**) As a result of the initial designation of this financial liability, the consolidated balances reported a loss of R$ 11,072 in the 1^st quarter 2019 (a loss of R$ 68,935 in the 1^st quarter 2018).

The classification of financial instruments in “amortized cost” or “fair value through profit or loss” is based on the portfolio business model and in thecharacteristics of expected cash flow for each instrument.

The financial instruments for which the carrying amounts approximate the fair values, due to their nature, at the end of the reporting year are:

· Financial assets: (i) consumers, concessionaires and licensees, (ii) leases, (iii) intercompany loans between associates, subsidiaries and parent company, (iv) receivables – CDE, (v) pledges, funds and restricted deposits, (vi) services rendered to third parties, (vii) collection agreements and (viii) sector financial asset;

· Financial liabilities: (i) trade payables, (ii) regulatory charges, (iii) use of public asset, (iv) consumers and concessionaires, (v) FNDCT/EPE/PROCEL, (vi) collection agreement, (vii) reversal fund, (viii) payables for business combination, (ix) tariff discounts – CDE and (x) sector financial liability.

In addition, in the first quarter of 2019 there were no transfers between the fair value hierarchy levels.

a) Measurement of financial instruments

As mentioned in note 4, the fair value of a security corresponds to its maturity value (redemption value) adjusted to present value by the discount factor (relating to the maturity date of the security) obtained from the market interest curve, in Brazilian reais.

The three levels of the fair value hierarchy are:

Level 1: Quoted prices in an active market for identical instruments;

Level 2: Observable inputs other than quoted prices in an active market that are observable for the asset or liability, directly (i.e. as prices) or indirectly (i.e. derived from prices);

Level 3: Instruments whose relevant factors are not observable market inputs.

As the distribution concessionaries classified the respective concession financial assets as fair value through profit or loss, the relevant factors for fair value measurement are not publicly observable. Therefore, the fair value hierarchy classification is level 3. The movements and respective gains (losses) in profit for or loss for the period are R$ 67,264 (R$ 66,637 in 2018) and the main assumptions are described in note 10 and 26.

Additionally, the main assumptions used in the fair value measurement of the zero-cost collar derivative, the fair value hierarchy of which is Level 3, are disclosed in note 33 b.1.

The Company recognizes in “Investments at cost” in the financial statements the 5.94% interest held by the indirect subsidiary Paulista Lajeado Energia S.A. in the total capital of Investco S.A. (“Investco”), in the form of 28,154,140 common shares and 18,593,070 preferred shares. As Investco’sshares are not traded on thestock exchange and the main objective of its operations is to generate electric energy for commercialization by the shareholders holding the concession, the Company opted to recognize the investment at cost, that is the best estimate of their fair value, since there are no available recent information for the fair value calculation, according to IFRS 9.

b) Derivatives

The Group has the policy of using derivatives to hedge against the risks of fluctuations in exchange and interest rates, without any speculative purposes. The Group has currency hedges in a volume compatible with the net exchange exposure, including all assets and liabilities tied to exchange rate changes.

The hedging instruments entered into by the Group are currency or interest rate swaps with no leverage component, margin call requirements or daily or periodic adjustments. Furthermore, in 2015 the subsidiary CPFL Geração contracted a zero-cost collar derivative (see item b.1 below).

As a large part of the derivatives entered into by the subsidiaries have their terms fully aligned with the hedged debts, and in order to obtain more relevant and consistent accounting information through the recognition of income and expenses, these debts were designated for the accounting recognition at fair value (notes 17 and 18). Other debts that have terms different from the derivatives contracted as a hedge continue to be recognized at amortized cost. Furthermore, the Group did not adopt hedge accounting for transactions with derivative instruments.

At March 31, 2019, the Group had the following swap transactions, all traded on the over-the-counter market:

(*)The effects on the income and comprehensive income of 2019 related to the fair value adjustments (MTM) of the derivatives are: (i) gains of R$ 18,876 for the debts designated at fair value, (ii) losses of R$ 49 for non- designated at fair value and (iii) losses of R$ 3,957 for other derivatives (zero cost collar).

As mentioned above, certain subsidiaries elected to fair value measrument debts for which they have fully debt-related derivatives instruments (note 17 and 18).

The Group has recognized gains and losses on their derivatives. However, as these derivatives are used as a hedging instrument, these gains and losses minimized the impacts of fluctuations in exchange and interest rates on the hedged debts. For the quarters ended at March 31, 2019 and 2018, the derivatives generated the following impacts on the consolidated profit or loss, recognized in the line item of Finance costs on monetary adjustment and exchange rate changes and in the consolidated comprehensive income in the credit risk in the fair value measurement related to debts at fair value.

b.1) Zero-cost collar derivative transactions entered into by CPFL Geração

In 2015, the subsidiary CPFL Geração entered into a transaction involving put options and call options in US$, both having the same institution as counterpart, and that combined are featured as a transaction usually known as zero-cost collar. Entering into this transaction does not have any speculative purpose, in as much as it is aimed at minimizing any negative impacts on future revenue of the joint venture ENERCAN, which has electric energy sale agreements with annual adjustment of part of the tariff based on the dollar variation. In addition, according to Management’s view, the scenario in 2015 was favorable to enter into this type of financial instrument, considering the high volatility implicit in dollar options and the fact that there is no initial cost for this type of transaction.

(Free Translation of the original in Portuguese)

Interim Standard Financial Statements – ITR – Date: March 31, 2019 - CPFL Energia S.A.

The total amount contracted was US$ 111,817 thousand, with due dates between October 1, 2015 and September 30, 2020. At March 31, 2019, the total amount contracted was US$ 44,083 thousand, considering the options already settled until this date. The strike prices of the dollar options vary from R$ 4.20 to R$ 4.40 for put options and from R$ 5.40 to R$7.50 for call options.

These options were measured at fair value in a recurring manner, as required by IFRS 9 /CPC 48. The fair value of the options that are part of this transaction was calculated based on the following assumptions:

Valuation technique(s) and key information	We used the Black Scholes Option Pricing Model, which aims to obtain the fair price of the options involving the following variables: value of the asset, strike price of the option, interest rate, term and volatility.
Significant unobservable inputs	Volatility determined based on the average market pricing calculations, future dollar and other variables applicable to this specific transaction, with average variation of 17.80%.
Relationship between unobservable inputs and fair value (sensitivity)	A slight rise in long-term volatility, analyzed separately, would result in an insignificant increase in fair value. If the volatility were 10% higher and all the other variables remained constant, the net carrying amount (asset) would increase by R$ 487, resulting in a net asset of R$ 15,826.

The following table reconciles the opening and closing balances of the call and put options for the 1^st quarter of 2019, as required by IFRS 13/CPC 46:

The fair value measurement of these financial instruments was recognized as finance income (expense) of the period, and no effects were recognized in other comprehensive income.

c) Concession financial assets - distribution

As the distribution subsidiaries have classified the respective financial assets of the concession as measured at fair value through profit or loss, the relevant factors to measure the fair value are not publicly observable and there is no active market. Therefore, the classification of the fair value hierarchy is level 3.

d) Market risk

Market risk is the risk that changes in market prices – e.g. foreign exchange rates and interest rates – will affect the Group’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return. The Group uses derivatives to manage market risks.

e) Sensitivity analysis

The Group performed sensitivity analyses of the main risks to which their financial instruments (including derivatives) are exposed, mainly comprising changes in exchange and interest rates.

When the risk exposure is considered asset, the risk to be taken into account is a reduction in the pegged indexes, due to a consequent negative impact on the Group’s profit or loss. Similarly, if the risk exposure is considered liability, the risk is of an increase in the pegged indexes and the consequent negative effect on the profit or loss. The Group therefore quantify the risks in terms of the net exposure of the variables (dollar, euro, CDI, IGP-M, IPCA, TJLP and SELIC), as shown below:

e.1) Exchange rates variation

Considering that the net exchange rate exposure at March 31, 2019 is maintained, the simulation of the effects by type of financial instrument for three different scenarios would be:

	Consolidated
				Income (expense) - R$ thousand
Instruments	Exposure (a)		Risk	Exchange depreciation of 3.7% (b)	Currency appreciation of 25% (c)	Currency appreciation of 50% (c)

(a) The exchange rate considered at 03/31/2019 was R$ 3.90 per US$ 1.00 and R$ 4.38 per €$ 1.00.

(b) As per the exchange rate curves obtained from information made available by B3 S.A., with the exchange rate being considered at R$ 4.04 and 4.67, and the currency depreciation at 3.70% and 6.74% for US$ and €$, respectively at 03/31/2019.

(c) As required by CVM Instruction No. 475/2008, the percentage increases in the ratios applied refer to the information made available by the B3 S.A..

(d) Owing to the characteristics of this derivative (zero-cost collar), the notional amount is presented in US$.

Except for the zero-cost collar, as the net exchange exposure of the dollar and the euro for the other derivative instruments is an asset, the risk is a drop in the dollar, and the euro, therefore, the exchange rate is appreciated by 25% and 50% in relation to the probable exchange rate.

e.2) Interest rates variation

Assuming that the scenario of net exposure of the financial instruments indexed to floating interest rates at March 2019 is maintained, the net finance cost for the next 12 months for each ofthe three scenarios defined, would be:

Additionally, the debts exposed to pre-fixed indexes would generate an expense of R$ 58,897.

f) Credit risk

Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations, and arises principally from the Group’s receivables from Consumers, Concessionaires and Licensees and financial instruments.Monthly, the risk is monitored and classified according to the current exposure, considering the limit approved by Management.

Impairment losses on financial assets recognized in profit or loss are presented in note 6 – Consumers, Concessionaires and Licensees.

Interim Standard Financial Statements – ITR – Date: March 31, 2019 - CPFL Energia S.A.

Consumers, Concessionaries and Licensees

The Group’s exposure to credit risk is influenced mainly by the individual characteristics of each customer. However, Management also considers the factors that may influence the credit risk.

The Group uses a provision matrix to measure the expected credit losses of trade receivables according to the consumer class (Residential, Commercial, Rural, Public Power, Public Lighting, Public Services), Other Revenues and Unbilled Revenue, comprising mostly a large number of dispersed balances.

Loss rates are based on actual credit loss experience over the past.

These rates reflect differences between economic conditions during the period over which the historical data have been collected, current conditions and the Group’s view of future economic conditions over the expected lives of the receivables. Accordingly, an “adjusted” revenue was calculated, reflecting the Group perception on expected loss. Such “adjusted” revenue was allocated by consumption class (matrix) according to the interval currently used in the allowance guided by the regulatory parameters as follows:

Class	Days	Period
Residential	90	Revenue of 3 months prior to the current month
Commercial and other revenues	180	Revenue of 6 months prior to the current month
Industrial, rural, public power in general	360	Revenue of 12 months prior to the current month
Unbilled	-	Uses revenue of the same month

Therefore, based on the assumptions above, an “Adjusted” ratio of the expected credit losses (“ECL”) allowance for the month is calculated, which was determined dividing the “Actual ECL” allowance by the “Adjusted Revenue” for each month. Then, the ECL allowance is estimated monthly, considering the respective moving average for the months of the "Adjusted” monthly ratios and applied to the actual revenue for the current month.

Based on this criterion, the ECL allowance percentage to be applied is changed monthly to the extent that the moving average is calculated.

The methodology used by Management includes a percentage that is compliant with the IFRS rule described as expected credit losses, including in a single percentage the probability of loss, weighted by the expected loss and possible outcomes, that is, includingProbability of default (“PD”),Exposure at default (“EAD”) and (“LGD”).

Macroeconomic factors

After studies developed by the Company to assess which variables present a correlation ratio with the actual amount of Expected Credit Losses Allowance, no ratios or macroeconomic factors that would have material impacts or that had direct correlation with the default level were identified, due to the electric sector characteristic of having instruments that mitigate the risk of losses, such as cutting energy supply to default customers.

Cash and cash equivalents

The Group limits its exposure to credit risk by investing only in liquid debt securities and only with counterparties that have a credit rating of at leastAA-.

(Free Translation of the original in Portuguese)

Interim Standard Financial Statements – ITR – Date: March 31, 2019 - CPFL Energia S.A.

The Group considers that its cash and cash equivalents have low credit risk based on the external credit ratings of the counterparties.Management did not identify for the quarter ended March 31, 2019 and the year ended December 31, 2018 that the securities had a significantly change in credit risk.

Derivatives

The Group adopts a policy of using derivatives with the purpose of hedge (economic hedge) against the risks of fluctuations in exchange rates and interest rates, mostly comprising currency and interest rate swaps. The derivative transactions are entered into with first-tier banks and financial institutions with a rating of at least AA-, based on the main credit rating agencies in the market (note 33). Management has not identified for the period of 2019 and the year 2018 that the derivative financial assets had a significant impairment using the criterion of expected losses.

The Group adopts a policy of providing financial guarantees for the obligations of its subsidiaries and joint ventures. As at March 31, 2019 and December 31, 2018, the Company had provided guarantees to certain financial institutions with respect to the credit lines granted to its subsidiaries and joint ventures, as presented in notes 17 and 18.

INDEPENDENT AUDITORS’ REPORT ON REVIEW OF INTERIM FINANCIAL INFORMATION

(A free translation of the original report in Portuguese, as filed with the Brazilian Securities and Exchange Commission (CVM), prepared in accordance with the accounting practices adopted in Brazil, rules of the CVM and of the International Financial Reporting Standards - IFRS)

To the Board of Directors and Shareholders of

CPFL Energia S.A.

Campinas - SP

Introduction

We have reviewed the accompanying individual and consolidated, interim financial information of CPFL Energia S.A. (“the Company”), included in the Quarterly Information Form - ITR, for the quarter ended March 31, 2019, which comprises the statement of financial position as of March 31, 2019 and the respective statements of profit or loss, other comprehensive income, changes in shareholders´ equity and cash flows for the three-month period then ended, comprising the explanatory notes.

Management is responsible for the preparation of the interim financial information in accordance with CPC 21(R1) Technical Pronouncement - Interim Financial Information and International Standard IAS 34 - Interim Financial Reporting, issued by International Accounting Standards Board - IASB, and for presentation of this interim financial information in accordance with the rules issued by Brazilian Securities and Exchange Commission (CVM) applicable to the preparation of the 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 the Brazilian and International Standard on Review Engagements (NBC TR 2410 -Revisão de Informações Intermediárias Executada pelo Auditor da Entidadeand 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. The scope of a review is substantially less than an audit conducted in accordance with auditing standards and, consequently, it 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 referred above is not prepared, in all material respects, in accordance with CPC 21 (R1) and the IAS 34, issued by IASB, applicable to the preparation of the Quarterly Information and presented in accordance with the rules issued by Brazilian Securities and Exchange Commission - CVM.

Other matters - Statements of Value Added

The individual and consolidated interim financial information, related to statements of value added (DVA) for the three-month period ended March 31, 2019, prepared under the responsibility of the Company's management, and presented as supplementary information for the purposes of IAS 34, were submitted to the same review procedures followed together with the review of the Company's interim financial information. In order to form our conclusion, we evaluated whether these statements are reconciled to the interim financial information and to the accounting records, as applicable, and whether their form and content are in accordance with the criteria set on Technical Pronouncement CPC 09 - Statement of Value Added. Based on our review, nothing has come to our attention that causes us to believe that the accompanying statements of value added are not prepared, in all material respects, in accordance with the individual and consolidated interim financial information taken as a whole.
