The amount raised was US$150 million. As time goes by, we have noted an increasing number of customers operating on our digital channels. Therefore, in addition to enhancing their experience in their relationship with Itaú Unibanco, we invest in cybersecurity to ensure the protection of our customers’ data. Our information security strategy was designed taking into account the global scenario, regulations and best market practices and standards. Our structure and governance are resilient and appropriate for identifying, detecting and reacting to threats, in addition to establishing recovery procedures for situations that require us to defend ourselves from cyberattacks. Furthermore, we invest in awareness campaigns for employees and customers, so that they are always alert to identify and deal with risks and threats. Besides the actions of Itaú Unibanco, we are seeing measures in the banking sector that benefit customers while encouraging access to credit products. In April 2019, a law was passed for automatic inclusion of customer data in the Positive Register. The automatic Positive Register is an important step for making credit cheaper in Brazil. By having access to the customer’s payment history over time, financial institutions, retail stores and other businesses will be in a better position to evaluate each consumer, thereby extending cheaper loans to good payers. In this respect, in 2017 we incorporated, with other banks, Quod, a company whose purpose is to create, reconcile and deal with Positive Register information. This measure is part of the Agenda BC+, led by the Central Bank in partnership with Febraban, to promote more financial citizenship, modernize legislation, enhance the efficiency of the National Financial System and offer cheaper credit. Zero cost on advances against single-installment credit card sales Clients of Rede with annual sales of up to R$ 30 million who use the Rede equipment, and receive their payments at Unibanco, will now receive the proceeds of their credit card sales in two days, free of charge for the advance as of May 2, 2019. This initiative applies to both current and new customers and aims to benefit small and medium companies, as well as the self-employed and micro entrepreneurs, and users of any model of the Rede device are eligible.

In the period from January to March 2019 we had a 5.6% increase in the net income attributable to owners of the parent company when compared to the same period of the previous year. Banking Product increased by 3.2%, mainly driven by revenues from credit operations due to the growth of credit portfolios of individuals and very small, small and middle-market companies. The increase in general and administrative expenses is associated to higher expenses related to credit cards, depreciation and amortization and the impact of the collective bargaining labor agreement on our personnel expenses Our credit portfolio, including financial guarantees provided and corporate securities, stood at R$650.6 billion at the end of March 2019, representing an increase of 7.4% over the same period of 2018. Worthy of note our Individuals portfolio, which rose by 12.0% and the Very Small, Small and Middle-Market Companies, with growth of 17.0%. Capital management is an essential component of our management model, because we use it to optimize the allocation of the shareholder’s funds and guaratee the solidess of the bank. These objectives are reflected in our policies on capital ratios and distribution of dividends that stipulate a minimum Full Tier I capital ratio of 13.5%. Thus, the distribution of dividends is conditional on this limit, the outlook for the growth of the business, the profitability for the year, mergers and acquisitions, changes in the market, and taxation and regulatory changes that could alter capital requirements. During 2018, our Full Tier I capital ratio continued to exceed the minimum limit, reaching 15.9% in December 2018, while in the first quarter of 2019 it stood at 14.6%. During this period, worthy of note is the generation of capital from income and the issuance of R$ 3.05 billion in Perpetual Subordinated Financial Notes, negotiated with professional investors, and approved by the Brazilian Central Bank as part of our supplementary capital, commencing February 2019. For Itaú Unibanco, the transparency of the results and the strategies discussed here are fundamental. Thus, on April 30, 2019 we published our Integrated Annual Report for 2018, in IFRS (International Financial Reporting Standards) the document in which we describe who we are, what we do and how we seek to create long-term value. We emphasize how our corporate governance drives our business, defines strategies and manages the main risks and opportunities. The 2018 Integrated Annual Report incorporates material changes in comparison with previous editions, notably: messages from the Co-chairmen of the Board of Directors and the Executive Committee; Management’s comments about the results; and integration with the Financial Statements. 0 8In the period from January to March 2019 we had a 5.6% increase in the net income attributable to owners of the parent company when compared to the same period of the previous year.

Independent Audit - CVM Instruction No. 381 Procedures Adopted by the Company: our operating policy, including subsidiaries, when contracting non-external audit-related services from our independent auditors, is based on applicable regulations and internationally accepted principles that protect the independence of the auditors. These principles state that: (a) the auditors must not audit their own work, (b) the auditors must not hold managerial positions at their clients and (c) the auditors must not promote their clients’ interests. In the period from January to March 2019, we did not contract from the independent auditors or their related parties services unrelated to the external audit in an amount exceeding 5% of the total fees regarding external audit services. As per CVM Instruction No. 381, we list below the other services provided and the dates on which they were contracted: - January 03 – issuance of the report of the review of income tax calculation and settlement; - January 18 – review of compliance with the regulations applicable to transfer pricing; - January 31 – review of the Tax Accounting Books; and - March 08 – acquisition of technical materials. Justification of the Independent Auditors PricewaterhouseCoopers: The provision of non-external audit-related services described above does not affect either independence or objectivity in conducting external audit examinations at Itaú Unibanco e and its subsidiaries. The policy for providing Itaú Unibanco with non-external audit-related services is based on principles that protect the independent auditors’ independence, all of which were observed in providing said services, including their approval by the Audit Committee of Itaú Unibanco. Brazilian Accounting Practices (BRGAAP) We disclosed the complete financial statements in accordance with Brazilian accounting practices (BRGAAP) at the same date of this publication, pursuant to CVM/SEP Circular Letter No. 01/13. The complete financial statements are available on the Investor Relations website of Itaú Unibanco (www.itau.com.br/investor-relations > Results Center). The Management Report and the Financial Statements of Itaú Unibanco Holding S.A. (Itaú Unibanco or Company) and its subsidiaries for the period from January to March 2019 follow the regulations established by the National Monetary Council (CMN), in accordance with International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB). New accounting standard IFRS 9 on financial instruments became effective on January 1, 2018. This standard introduces significant amendments to classification and measurement, impairment and hedge accounting. The most significant change resulting from IFRS 9 is how banks account for loan losses. As from IFRS 9 these will be addressed as expected rather than incurred, as before. The information presented in this material is available on the Investor Relations website of Itaú Unibanco (www.itau.com.br/investor-relations > Results Center) and on the websites of CVM and of the Securities and Exchange Commission (SEC). 1 1Independent Audit - CVM Instruction No. 381 Procedures Adopted by the Company: our operating policy, including subsidiaries, when contracting non-external audit-related services from our independent auditors, is based on applicable regulations and internationally accepted principles that protect the independence of the auditors.

These st changes are effective for the years started on January 1 , 2020 and possible impacts are being assessed and will be completed by the date they are in force. · IFRS 17 – Insurance Contracts: The pronouncement replaces IFRS 4 – Insurance Contracts and presents three approaches for assessment: · General Model: applicable to all contracts without direct participation features; Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 20

· Premium Allocation Approach (PAA): applicable to contracts which term is up to 12 months and with modestly complex cash flows. It is simpler than the standard model; and it can be used only when it produces results similar to those that would be obtained it the standard model was used; · Variable Fee Approach: applicable to insurance contracts with direct participation features. The insurance contracts are substantially investment related service contracts under which an entity promises an investment return based on underlying items. Insurance contracts should be recognized based on the analysis of four components: · Expected Future Cash Flows: estimate of all components of cash flow of the contract, considering inflows and outflows; · Risk Adjustment: estimate of offset required by deviations that may occur between cash flows; · Contractual Margin: difference between any amounts received before the beginning of the contract coverage and present value of cash flows estimated in the beginning of the contract; · Discount: projected cash flows should be discounted at present value, to reflect the time value of money, at rates that reflect the characteristics of respective flows. st This standard is effective for annual periods beginning on January 1 , 2021. Possible impacts are being assessed and will be completed by the date this standard is effective. 2.3. Critical accounting estimates and judgments The preparation of Consolidated Financial Statements in accordance with IFRS requires Management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and contingent assets and liabilities at the date of the Consolidated Financial Statements, due to uncertainties and high level of subjectivity involved in the recognition and measurement of certain items. Estimates and judgments considered more relevant by ITAÚ UNIBANCO HOLDING are detailed below: a) Consolidation Controlled entities are all entities to which ITAÚ UNIBANCO HOLDING is exposed, or is entitled to variable returns of involvement with the entity and that can affect these returns through its power on the entity.Control assessment is conducted on a continuous basis. Controlled entities are consolidated from the date control is established to the date on which control ceases to exist. b) Goodwill The review of goodwill due to impairment reflects the Management's best estimate for future cash flows of Cash Generating Units (CGU). These flows are subject to market conditions and uncertain factors, such as: · Cash flows projected for periods of available forecasts and long-term assumptions for these flows; · Discount rates, since they generally reflect financial and economic variables, such as risk-free interest rate and a risk premium. c) Expected Credit Loss The measurement of expected credit loss requires the application of significant assumptions, such as: · Maturity term: ITAÚ UNIBANCO HOLDING considers the maximum contractual period on which it will be exposed to financial instrument’s credit risk. However, the estimated useful life of assets that do not have a determined maturity is based on the period of exposure to credit risk. Additionally, all contractual terms are considered when determining the expected life, including prepayment and rollover options. · Prospective information: IFRS 9 requires a balanced and impartial estimate of credit loss that comprises forecasts of future economic conditions. ITAÚ UNIBANCO HOLDING uses prospective macroeconomic information and public information with projections prepared internally to determine the impact of these estimates on the calculation of expected credit loss.

· Probability-weighted loss scenarios: ITAÚ UNIBANCO HOLDING uses weighted scenarios to determine credit loss expected in a proper observation horizon. · Determining criteria for significant increase or decrease in credit risk: in each period of the consolidated financial statements, ITAÚ UNIBANCO HOLDING assesses whether the credit risk on a financial asset has increased significantly using relative and absolute triggers (indicators) by product and by country. Brazilian and foreign government securities are considered with low credit risk, and therefore they remain in stage 1, in accordance with a study conducted by ITAÚ UNIBANCO HOLDING. Significant increase in credit risk: ITAÚ UNIBANCO HOLDING assesses several factors to determine a significant increase in credit risk, such as: the counterparty, type and characteristics of the product and region in which it was taken out, considering the following objective criteria as minimum factors: · Phase 1 to phase 2: default exceeding 30 days, except for payroll loans for public bodies, which recognition is made after 45 days in arrears; · Phase 2 to phase 3: default exceeding 90 days, except for the mortgage loan portfolio, which uses 180 days in arrears as a parameter for phase migration. ITAÚ UNIBANCO HOLDING assesses whether the credit risk has significantly increased on an individual or collective basis. For collective assessment purposes, financial assets are grouped based on characteristics of shared credit risk, considering the type of instrument, credit risk classifications, initial recognition date, remaining term, industry, geographical location of the counterparty, among other significant factors. Macroeconomic scenarios: This information involves inherent risks, market uncertainties and other factors that may give rise to results different from expected, including changes in market conditions and economic policy, recessions or fluctuations in indicators different from expected. d) Change to Financial Assets The factors used to determine whether there was substantial change to a contract are: change to contractual cash flows and significant extensions in the operation term due to the debtor's financial constraints, significant changes to interest rate and changes to the currency in which the operation is denominated. e) Transfer of Financial Assets Financial assets are written off when all their risks and benefits are transferred. In this assessment, ITAÚ UNIBANCO HOLDING considers if: there is no obligation to make payments unless the due amounts are received (assets); there is no prohibition to sell these assets or pledge them as guarantee; and there is no obligation to send all proceedings received from assets without a significant delay. f) Derecognition of Financial Assets When there are no reasonable expectations of recovery of a financial asset, considering historical curves, its total or partial derecognition is carried out concurrently with the use of the related allowance for expected credit loss, with no effect on the Consolidated Statement of Income of ITAÚ UNIBANCO HOLDING. Subsequent recoveries of amounts previously written off are accounted for as income in the Consolidated Statement of Income. g) Deferred income tax and social contribution As explained in Note 2.4j, deferred tax assets are recognized only in relation to temporary differences and tax assets and loss for offset to the extent it is probable that ITAÚ UNIBANCO HOLDING will generate future taxable profit for its use. The expected realization of deferred tax assets is based on the projection of future taxable profits and technical studies, as disclosed in Note 24.

h) Fair value of financial instruments, including derivatives The fair value of financial instruments, including Derivatives that are not traded in active markets is calculated by using valuation techniques based on assumptions that consider market information and conditions. The main assumptions are: historical data, information on similar transactions and pricing techniques. For more complex or illiquid instruments, significant judgment is necessary to determine the model used with the selection of specific inputs and, in certain cases, evaluation adjustments are applied to the model amount our price quoted for financial instruments that are not actively traded. The methodologies used to estimate the fair value of certain financial instruments are described in Note 28. i) Defined benefit pension plan The current amount of pension plans is obtained from actuarial calculations, which use assumptions as discount rate, which is appropriated at the end of each year and used to determine the present value of estimated future cash outflows. To determine the appropriate discount rate, ITAÚ UNIBANCO HOLDING considers the interest rates of National Treasury Notes that have maturity terms approximating the terms of the respective liabilities. The main assumptions on Pension plan obligations are based on, in part, current market conditions. Additional information is disclosed in Note 26. j) Provisions, contingencies and legal liabilities ITAÚ UNIBANCO HOLDING periodically reviews its contingencies. These contingencies are evaluated based on Management´s best estimates, taking into account the opinion of legal counsel when there is a likelihood that financial resources will be required to settle the obligations and the amounts may be reasonably estimated. Contingencies classified as probable losses are recognized in the Balance Sheet under Provisions. Contingent amounts are measured using appropriate models and criteria, despite the uncertainty surrounding the ultimate timing and amounts. Provisions, contingencies and other commitments are detailed in Note 29. k) Technical provisions for insurance and private pension Technical provisions are liabilities arising from obligations of ITAÚ UNIBANCO HOLDING to its policyholders and participants. These obligations may be short term liabilities (property and casualty insurance) or medium and long term liabilities (life insurance and pension plans). The determination of the actuarial liability is subject to several uncertainties inherent in the coverage of insurance and pension contracts, such as assumptions of persistence, mortality, disability, life expectancy, morbidity, expenses, frequency and severity of claims, conversion of benefits into annuities, redemptions and return on assets. The estimates for these assumptions are based on the historical experience of ITAÚ UNIBANCO HOLDING, benchmarks and experience of the actuary, in order to comply with best market practices and the continuous review of the actuarial liability. The adjustments resulting from these continuous improvements, when necessary, are recognized in the statement of income for the corresponding period. Additional information is described in Note 27.

II. Business combinations In general, a business consists of an integrated set of activities and assets that may be conducted and managed so as to provide a direct return, as dividends, lower costs or other economic benefits, to investors or other stockholders, members or participants. There is goodwill in a set of activities and transferred assets, it is presumed to be a business. The acquisition method is used to account for business combinations, except for those classified as under common control. The acquisition cost is measured at the fair value of the assets transferred, equity instruments issued and liabilities incurred or assumed at the acquisition date, plus costs directly attributable to the acquisition. Acquired assets and assumed liabilities and contingent liabilities identifiable in a business combination are initially measured at fair value at the date of acquisition, regardless of the existence of non-controlling interests. When the amount paid, plus non-controlling interests, is higher than the fair value of identifiable net assets acquired, the difference will be account for as goodwill. On the other hand, if the difference is negative, it will be addressed as bargain purchase gain and the amount will be recognized directly in income. III. Goodwill Goodwill is not amortized, but its recoverable amount is assessed semi-annually or when there is indication an of impairment loss event, using an approach that involves the identification of cash- generating units (CGU) and estimates of fair value less cost to sell and/or value in use. Cash-generating units or groups are identified in the lowest level in which the goodwill is monitored for internal management purposes. Goodwill is allocated for cash flow generating units for purposes of testing the recoverable amount. Goodwill of associates and joint ventures is reported as part of investment in the Consolidated Balance Sheet under Investments in Associates and Joint Ventures and the recoverable amount analysis is carried out in relation to the total balance of the investments (including goodwill). IV. Capital Transactions with non-controlling stockholders IFRS 10 – Consolidated Financial Statements establishes that, changes in an ownership interest in a subsidiary, which do not result in a loss of control, are accounted for as capital transactions and any difference between the amount paid and the carrying amount of non-controlling stockholders is recognized directly in consolidated stockholders' equity. b) Foreign currency translation I. Functional and presentation currency The Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING are presented in Brazilian Reais, which is its functional and presentation currency. For each subsidiary and investment in associates and joint ventures, ITAÚ UNIBANCO HOLDING defined the functional currency, as the currency of the primary economic environment in which the entity operates. II. Foreign currency operations Foreign currency operations are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses are recognized in the consolidated statement of income, unless they are related to cash flow hedge, when they are recognized in stockholders’ equity.

c) Cash and cash equivalents It is defined as cash and current accounts in banks, considered in the Consolidated Balance Sheet in the heading Cash, Interbank Deposits and Securities purchased under agreements to resell that have original maturities of up to 90 days or less. d) Financial assets and liabilities Financial assets and liabilities are initially recognized at fair value and subsequently measured at amortized cost or fair value. I - Classification and Measurement of Financial Assets st As from January 1 , 2018, ITAÚ UNIBANCO HOLDING applies IFRS 9 – Financial Instruments and classified its financial assets in the following measurement categories: · Amortized Cost: used when financial assets are managed to obtain contractual cash flows, constituted solely of payments of principal and interest; · Fair Value Through Other Comprehensive Income: used when financial assets are held both for obtaining contractual cash flows, constituted solely by payments of principal and interest, and for sale; and · Fair Value Through Profit or Loss: used for financial assets that do not meet the aforementioned criteria. The classification and subsequent measurement of financial assets depend on: · The business model under which they are measured; · The characteristics of its cash flows (Solely Payment of Principal and Interest Test – SPPI Test). Business model: represents how financial assets are managed to generate cash flows and does not depend on the Management’s intention regarding an individual instrument. Financial assets may be managed with the purpose of: i) obtaining contractual cash flows; ii) obtaining contractual cash flows and sale; or iii) others. To assess business models, ITAÚ UNIBANCO HOLDING considers risks that affect the performance of business model; how business managers are compensated; and how the performance of business model is assessed and reported to Management. When the financial asset is maintained in business models i) and ii) the application of the SPPI Test is required. SPPI Test: assessment of cash flows generated by financial instrument with the purpose of checking whether they represent solely payments of principal and interest. To fit into this concept, cash flows should include consideration for the time value of money and credit risk. If contractual terms introduce risk exposure or cash flow volatilities, such as exposure to changes in prices of equity instruments or prices of commodities, the financial asset is classified at fair value through profit or loss. Hybrid contracts should be assessed as a whole, including all embedded characteristics. The accounting of a hybrid contract that contains an embedded derivative is performed on a joint basis, i.e. the whole instrument is measured at fair value through profit or loss. Amortized Cost The amortized cost is the amount through which the financial asset or liability is measured at the initial recognition, plus updates performed using the effective interest method, less amortization of principal and interest, adjusted for any provision for expected credit loss.

Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 27

Effective Interest Rate The effective interest rate is the rate that discounts estimated future receipts or payments over the expected life of the financial asset or liability. To calculate the effective interest rate, ITAÚ UNIBANCO HOLDING estimates cash flows including all contractual terms of the financial instrument, but does not include future credit losses. The calculation includes all commissions paid or received between parties to the contract, transaction costs, and all other premiums or discounts. The interest revenue is calculated by applying the effective interest rate to the gross carrying amount of a financial asset. In case of purchased or originated credit impaired financial assets, the adjusted effective interest rate is applied (considers the expected credit loss) at the amortized cost of the financial asset. Fair Value Fair value is the price that would be received for the sale of an asset or that would be paid for the transfer of a liability in a normal transaction between market players on the measurement date. ITAÚ UNIBANCO HOLDING classifies the fair value hierarchy according to the relevance of data observed in the measurement process. Details of the fair value of financial instruments, including Derivatives, as well as about the hierarchy of fair value are detailed in Note 28. The average cost is used to determine the gains and losses realized on disposal of financial assets at fair value, which are recorded in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities. Dividends on assets at fair value through other comprehensive income are recognized in the Consolidated Statement of Income as Dividend income when it is probable that ITAÚ UNIBANCO HOLDING’s right to receive such dividends is established. Regular purchases and sales of financial assets are recognized and derecognized, respectively, on the trade date. Financial assets are derecognized when rights to receive cash flows expire or when ITAÚ UNIBANCO HOLDING transfers substantially all risks and rewards of ownership, and such transfer qualifies for derecognition. Otherwise, control should be assessed to determine whether the continuous involvement related to any retained control does not prevent derecognition. Financial assets and liabilities are offset against each other and the net amount is reported in the Balance Sheet solely when there is a legally enforceable right to offset the recognized amounts and intention to settle them on a net basis, or simultaneously realize the asset and settle the liability. Equity Instruments An equity instrument is any contract that evidences a residual interest in an entity’s assets, after the deduction of all its liabilities, such as Shares and Units. ITAÚ UNIBANCO HOLDING subsequently measures all its equity instruments at fair value through profit or loss, except when Management opts, in the initial recognition, for irrevocably designating an equity instrument at fair value through other comprehensive income if it is held with a purpose other than only generating returns. When this option is selected, gains and losses on the fair value of an instrument are recognized in the Consolidated Statement of Comprehensive Income and are not subsequently reclassified to the Consolidated Statement of Income, even in the sale. Dividends continue being recognized in the Consolidated Statement of Income when ITAÚ UNIBANCO HOLDING’s right is established. Gains and losses on equity instruments measured at fair value through profit or loss are accounted for in the Consolidated Statement of Income.

Expected Credit Loss ITAÚ UNIBANCO HOLDING assesses on a forward-looking basis the expected credit loss associated with financial assets measured at amortized cost or through other comprehensive income, loan commitments and financial guarantee contracts: · Financial assets: loss is measured at present value of the difference between contractual cash flows and cash flows that ITAÚ UNIBANCO HOLDING expects to receive; · Loan commitments: expected loss is measured at present value of the difference between contractual cash flows that would be due if the commitment was drawn down and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive; · Financial guarantees: the loss is measured at the difference between the payments expected for refunding the counterparty and the amounts that ITAÚ UNIBANCO HOLDING expects to recover. ITAÚ UNIBANCO HOLDING applies the three-stage approach to measure the expected credit loss, in which financial assets migrate from one stage to the other in accordance with changes in credit risk. · Stage 1 – 12-month expected credit loss: represents default events possible within 12 months. Applicable to financial assets purchased or originated credit impaired financial assets; · Stage 2 – Lifetime expected credit loss of financial instrument: considers all possible default events. Applicable to financial assets purchased or originated credit impaired financial assets and which credit risk has increased significantly; and · Stage 3 – Credit loss expected for credit-impaired assets: considers all possible default events. Applicable to financial assets purchased or originated credit impaired financial assets. The measurement of assets classified in this stage is different from Stage 2 due to the recognition of interest income by applying the effective interest rate at amortized cost (net of provision) rather than at the gross carrying amount. An asset will migrate from a phase as its credit risk increases or decreases. Therefore, a financial asset that migrated to phases 2 and 3 may return to phase 1, unless it was purchased or originated credit impaired financial assets. Macroeconomic Scenarios Prospective information is based on macroeconomic scenarios that are reassessed annually or when market conditions so require. Changes in Contractual Cash Flows When contractual cash flows of a financial asset are renegotiated or otherwise modified and this does not substantially change its terms and conditions, ITAÚ UNIBANCO HOLDING does not derecognize it. However, the gross carrying amount of this financial asset is recalculated as the present value of contractual cash flows renegotiated or changed, discounted at the original effective interest rate and a modification gain or loss is recognized in profit or loss. Any costs or fees incurred adjust the modified carrying amount and are amortized over the remaining term of the financial asset. If, on the other hand, the renegotiation or change substantially modifies the terms and conditions of the financial asset, ITAÚ UNIBANCO HOLDING derecognises the original asset and recognizes a new one. Accordingly, the renegotiation date is considered the initial recognition date of the new asset for expected credit loss calculation purposes, including to determine significant increases in credit risk. ITAÚ UNIBANCO HOLDING also assesses if the new financial asset may be considered as purchased or originated credit impaired financial assets, particularly when the renegotiation was motivated by the debtor’s financial constraints. Differences between the carrying amount of the original asset and fair value of the new asset are immediately recognized in the Consolidated Statement of Income. Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 29 Expected Credit Loss ITAÚ UNIBANCO HOLDING assesses on a forward-looking basis the expected credit loss associated with financial assets measured at amortized cost or through other comprehensive income, loan commitments and financial guarantee contracts: · Financial assets: loss is measured at present value of the difference between contractual cash flows and cash flows that ITAÚ UNIBANCO HOLDING expects to receive; · Loan commitments: expected loss is measured at present value of the difference between contractual cash flows that would be due if the commitment was drawn down and the cash flows that ITAÚ UNIBANCO HOLDING expects to receive; · Financial guarantees: the loss is measured at the difference between the payments expected for refunding the counterparty and the amounts that ITAÚ UNIBANCO HOLDING expects to recover.

If, on the other hand, the renegotiation or change substantially modifies the terms and conditions of the financial asset, ITAÚ UNIBANCO HOLDING derecognises the original asset and recognizes a new one. Accordingly, the renegotiation date is considered the initial recognition date of the new asset for expected credit loss calculation purposes, including to determine significant increases in credit risk. ITAÚ UNIBANCO HOLDING also assesses if the new financial asset may be considered as purchased or originated credit impaired financial assets, particularly when the renegotiation was motivated by the debtor’s financial constraints. Differences between the carrying amount of the original asset and fair value of the new asset are immediately recognized in the Consolidated Statement of Income.

The effects of changes to cash flows of financial assets and other details about methodologies and assumptions adopted by Management to measure the allowance for expected credit loss, including the use of prospective information, are detailed in Note 32. Transfer of Financial Assets ITAÚ UNIBANCO HOLDING derecognizes a financial asset, or a portion of a financial asset, from its Balance sheet when it transfers substantially all the risks and rewards of ownership of the financial asset. If ITAÚ UNIBANCO HOLDING neither transfers nor retains substantially all the risks and rewards of ownership of the financial asset, it determines whether was retained control of the financial asset. When ITAÚ UNIBANCO HOLDING retains control, it continues to recognize the financial asset to the extent of its continuing involvement in the financial asset and consideration received is accounted for as a financial liability. II – Classification and Measurement of Financial Liabilities Financial liabilities are initially recognized at fair value and subsequently measures at amortized cost, except for: · Financial Liabilities at Fair Value Through Profit or Loss: classification applied to derivatives and other financial liabilities designated at fair value through profit or loss to reduce “accounting mismatches”. ITAÚ UNIBANCO HOLDING irrevocably designates financial liabilities at fair value through profit or loss in the initial recognition (fair value option), when the option eliminates or significantly reduces measurement or recognition inconsistencies. · Loan Commitments and Financial Guarantees, as detailed in Note 2.4d Vll. Derecognition and Change of Financial Liabilities ITAÚ UNIBANCO HOLDING derecognition a financial liability from the Consolidated Balance Sheet when it is extinguished, i.e., when the obligation specified in the contract is discharged, cancelled or expires. A debt instrument change or substantial terms modification of a financial liability is accounted as a derecognition of the original financial liability and a new one is recognized. A substantial change to contractual terms occurs when the present value of cash flow discount under the new terms, including any rates paid/received and discounted using the original effective interest rate, is at least 10% different from discounted present value of cash flow remaining from original financial liabilities. III – Securities purchased under agreements to resell ITAÚ UNIBANCO HOLDING has purchased securities with resale agreement (resale agreements), and sold securities with repurchase agreement (repurchase agreement) of financial assets. Resale and repurchase agreements are accounted for under Securities purchased under agreements to resell and Securities sold under repurchase agreements, respectively. The difference between the sale and repurchase prices is treated as interest and recognized over the life of the agreements using the effective interest rate method. The financial assets accepted as collateral in our resale agreements can be used by us, if provided for in the agreements, as collateral for our repurchase agreements or can be sold. IV - Derivatives All derivatives are accounted for as financial assets when the fair value is positive and as financial liabilities when the fair value is negative. The assessment of active hybrid contracts that are in the scope of IFRS 9 is carried out as a whole, including all embedded characteristics, whereas the accounting is carried out on a joint basis, i.e. the whole instrument is measured at fair value through profit or loss. Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 30 The effects of changes to cash flows of financial assets and other details about methodologies and assumptions adopted by Management to measure the allowance for expected credit loss, including the use of prospective information, are detailed in Note 32. Transfer of Financial Assets ITAÚ UNIBANCO HOLDING derecognizes a financial asset, or a portion of a financial asset, from its Balance sheet when it transfers substantially all the risks and rewards of ownership of the financial asset. If ITAÚ UNIBANCO HOLDING neither transfers nor retains substantially all the risks and rewards of ownership of the financial asset, it determines whether was retained control of the financial asset. When ITAÚ UNIBANCO HOLDING retains control, it continues to recognize the financial asset to the extent of its continuing involvement in the financial asset and consideration received is accounted for as a financial liability. II – Classification and Measurement of Financial Liabilities Financial liabilities are initially recognized at fair value and subsequently measures at amortized cost, except for: · Financial Liabilities at Fair Value Through Profit or Loss: classification applied to derivatives and other financial liabilities designated at fair value through profit or loss to reduce “accounting mismatches”. ITAÚ UNIBANCO HOLDING irrevocably designates financial liabilities at fair value through profit or loss in the initial recognition (fair value option), when the option eliminates or significantly reduces measurement or recognition inconsistencies. · Loan Commitments and Financial Guarantees, as detailed in Note 2.4d Vll. Derecognition and Change of Financial Liabilities ITAÚ UNIBANCO HOLDING derecognition a financial liability from the Consolidated Balance Sheet when it is extinguished, i.e., when the obligation specified in the contract is discharged, cancelled or expires. A debt instrument change or substantial terms modification of a financial liability is accounted as a derecognition of the original financial liability and a new one is recognized. A substantial change to contractual terms occurs when the present value of cash flow discount under the new terms, including any rates paid/received and discounted using the original effective interest rate, is at least 10% different from discounted present value of cash flow remaining from original financial liabilities. III – Securities purchased under agreements to resell ITAÚ UNIBANCO HOLDING has purchased securities with resale agreement (resale agreements), and sold securities with repurchase agreement (repurchase agreement) of financial assets. Resale and repurchase agreements are accounted for under Securities purchased under agreements to resell and Securities sold under repurchase agreements, respectively. The difference between the sale and repurchase prices is treated as interest and recognized over the life of the agreements using the effective interest rate method. The financial assets accepted as collateral in our resale agreements can be used by us, if provided for in the agreements, as collateral for our repurchase agreements or can be sold.

When a contract has a host component outside the scope of IFRS 9, such as a lease agreement receivable or an insurance contract, or even a financial liability, embedded derivatives are treated as separate financial instruments if: (i) Respective characteristics and economic risks are not closely related to those of the main component; (ii) the separate instrument meets the definition of derivative; and (iii) the underlying instrument is not account for at fair value through profit or loss. These embedded derivatives are accounted for separately at fair value, with variations recognized in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities. ITAÚ UNIBANCO HOLDING will continue applying all accounting hedge requirements set forth in IAS 39; however, it may adopt the requirements of IFRS 9, according to the Management’s decision. According to this standard, derivatives may be designated and qualified as hedge instruments for accounting purposes and, depending on the nature of the hedged item, the method for recognizing gains or losses of fair value will be different. ITAÚ UNIBANCO HOLDING documents, in the beginning of the hedge transaction, the relationship between hedge instruments and protected items, as well as its management risk purpose and strategy. Hedge is assessed on an ongoing basis and it is determined as having been highly effective throughout all periods of the Financial Statements for which it was designated. IAS 39 presents three hedge strategies: fair value hedge, cash flow hedge, and hedge of net investments in a foreign operation. ITAÚ UNIBANCO HOLDING uses derivatives as hedging instruments under the three hedge strategies, as detailed in Note 7. Fair value hedge The following practices are adopted for these operations: a) The gain or loss arising from the new measurement of the hedge instrument at fair value should be recognized in income; and b) The gain or loss arising from the hedged item, attributable to the effective portion of the hedged risk, should adjust the book value of the hedged item and also be recognized in income. When the derivative expires or is sold or the hedge no longer meets the accounting hedge criteria or in the event the designation is revoked, the accounting hedge should be prospectively discontinued. In addition, any adjustment in the book value of the hedged item should be amortized in income. Cash flow hedge For derivatives that are designated and qualify as a cash flow hedge, the effective portion of derivative gains or losses are recognized in Other comprehensive income – Cash flow hedge, and reclassified to Income in the same period or periods in which the hedged transaction affects income. The portion of gain or loss on derivatives that represents the ineffective portion or the hedge components excluded from the assessment of effectiveness is recognized immediately in income. Amounts originally recorded in Other comprehensive income and subsequently reclassified to Income are recorded in the corresponding income or expense lines corresponding to the hedged item. When the derivative expires or is sold, when the hedge no longer meets the accounting hedge criteria or when the entity revokes the designation, any cumulative gain or loss existing in Other comprehensive income should be kept recognized in stockholders’ equity until the expected transaction occurs or is no longer expected to occur, when the hedged item is ultimately recognized in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss recognized in Other Comprehensive Income is immediately transferred to the statement of income. Hedge of net investments in foreign operations The hedge of a net investment in a foreign operation, including hedge of a monetary item that is accounted for as part of the net investment, is accounted for in a manner similar to a cash flow hedge: Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 31 When a contract has a host component outside the scope of IFRS 9, such as a lease agreement receivable or an insurance contract, or even a financial liability, embedded derivatives are treated as separate financial instruments if: (i) Respective characteristics and economic risks are not closely related to those of the main component; (ii) the separate instrument meets the definition of derivative; and (iii) the underlying instrument is not account for at fair value through profit or loss. These embedded derivatives are accounted for separately at fair value, with variations recognized in the Consolidated Statement of Income as Adjustments to Fair Value of Financial Assets and Liabilities. ITAÚ UNIBANCO HOLDING will continue applying all accounting hedge requirements set forth in IAS 39; however, it may adopt the requirements of IFRS 9, according to the Management’s decision. According to this standard, derivatives may be designated and qualified as hedge instruments for accounting purposes and, depending on the nature of the hedged item, the method for recognizing gains or losses of fair value will be different. ITAÚ UNIBANCO HOLDING documents, in the beginning of the hedge transaction, the relationship between hedge instruments and protected items, as well as its management risk purpose and strategy. Hedge is assessed on an ongoing basis and it is determined as having been highly effective throughout all periods of the Financial Statements for which it was designated. IAS 39 presents three hedge strategies: fair value hedge, cash flow hedge, and hedge of net investments in a foreign operation. ITAÚ UNIBANCO HOLDING uses derivatives as hedging instruments under the three hedge strategies, as detailed in Note 7. Fair value hedge The following practices are adopted for these operations: a) The gain or loss arising from the new measurement of the hedge instrument at fair value should be recognized in income; and b) The gain or loss arising from the hedged item, attributable to the effective portion of the hedged risk, should adjust the book value of the hedged item and also be recognized in income. When the derivative expires or is sold or the hedge no longer meets the accounting hedge criteria or in the event the designation is revoked, the accounting hedge should be prospectively discontinued. In addition, any adjustment in the book value of the hedged item should be amortized in income. Cash flow hedge For derivatives that are designated and qualify as a cash flow hedge, the effective portion of derivative gains or losses are recognized in Other comprehensive income – Cash flow hedge, and reclassified to Income in the same period or periods in which the hedged transaction affects income. The portion of gain or loss on derivatives that represents the ineffective portion or the hedge components excluded from the assessment of effectiveness is recognized immediately in income. Amounts originally recorded in Other comprehensive income and subsequently reclassified to Income are recorded in the corresponding income or expense lines corresponding to the hedged item. When the derivative expires or is sold, when the hedge no longer meets the accounting hedge criteria or when the entity revokes the designation, any cumulative gain or loss existing in Other comprehensive income should be kept recognized in stockholders’ equity until the expected transaction occurs or is no longer expected to occur, when the hedged item is ultimately recognized in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss recognized in Other Comprehensive Income is immediately transferred to the statement of income. Hedge of net investments in foreign operations The hedge of a net investment in a foreign operation, including hedge of a monetary item that is accounted for as part of the net investment, is accounted for in a manner similar to a cash flow hedge: Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 31

a) The portion of gain or loss on the hedge instrument determined as effective is recognized in other comprehensive income; b) The ineffective portion is recognized in income. Gains or losses on the hedging instrument related to the effective portion of the hedge which is recognized in comprehensive income is reclassified to income for the period when the foreign operation is partially or totally sold. V - Loan operations ITAÚ UNIBANCO HOLDING classifies a loan operation as on non-accrual status if the payment of the principal or interest has been in default for 60 days or more. In this case, accrual of interest is no longer recognized. VI - Capitalization plans In Brazil they are regulated by the insurance regulator. These plans do not meet the definition of an insurance contract under IFRS 4, and therefore they are classified as a financial liability at amortized cost under IFRS 9. Revenue from capitalization plans is recognized during the period of the contract and measured as the difference between the amount deposited by the client and the amount that ITAÚ UNIBANCO HOLDING has to reimburse. VII – Loan Commitments and Financial Guarantees ITAÚ UNIBANCO HOLDING recognizes in the Consolidated Balance Sheet, as an obligation, on the issue date, the fair value of loan commitments and financial guarantees. The fair value is generally represented by the fee charged from the client. This amount is amortized for the instrument term and is recognized in the Consolidated Statement of Income in the heading Banking service fees. After the issue, based on the best estimate, if ITAÚ UNIBANCO HOLDING concludes that the credit loss expected in relation to the guarantee issued is higher that the fair value less accumulated amortization, this amount is replaced by a provision for loss. e) Investments in associates and joint ventures I – Associates Associates are companies in which the investor has a significant influence but does not hold control. Investments in these companies are initially recognized at cost of acquisition and subsequently accounted for using the equity method. Investments in associates and joint ventures include the goodwill identified upon acquisition, net of any cumulative impairment loss. II – Joint arrangements ITAÚ UNIBANCO HOLDING defines a joint arrangements when it is entitled to rights and obligations for liabilities related to the business. ITAÚ UNIBANCO HOLDING’s share in profits or losses of its associates and joint ventures after acquisition is recognized in the Consolidated statement of income. Its share of the changes in the share in OCI of corresponding stockholders’ equity of its associates and joint ventures is recognized in its own reserves of stockholders’ equity. The cumulative changes after acquisition are adjusted against the carrying amount of the investment. When the ITAÚ UNIBANCO HOLDING share of losses of an associates and joint ventures is equal or above its interest in the associates and joint ventures, including any other receivables, ITAÚ UNIBANCO HOLDING does not recognize additional losses, unless it has incurred any obligations or made payments on behalf of the associates and joint ventures. Unrealized profits on transactions between ITAÚ UNIBANCO HOLDING and its associates and joint ventures are eliminated to the extent of the interest of ITAÚ UNIBANCO HOLDING. Unrealized losses are also eliminated, unless the transaction provides evidence of impairment of the transferred asset. The accounting policies on associates and joint ventures are consistent with the policies adopted by ITAÚ UNIBANCO HOLDING. Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 32 a) The portion of gain or loss on the hedge instrument determined as effective is recognized in other comprehensive income; b) The ineffective portion is recognized in income. Gains or losses on the hedging instrument related to the effective portion of the hedge which is recognized in comprehensive income is reclassified to income for the period when the foreign operation is partially or totally sold. V - Loan operations ITAÚ UNIBANCO HOLDING classifies a loan operation as on non-accrual status if the payment of the principal or interest has been in default for 60 days or more. In this case, accrual of interest is no longer recognized. VI - Capitalization plans In Brazil they are regulated by the insurance regulator.

The fair value is generally represented by the fee charged from the client. This amount is amortized for the instrument term and is recognized in the Consolidated Statement of Income in the heading Banking service fees. After the issue, based on the best estimate, if ITAÚ UNIBANCO HOLDING concludes that the credit loss expected in relation to the guarantee issued is higher that the fair value less accumulated amortization, this amount is replaced by a provision for loss. e) Investments in associates and joint ventures I – Associates Associates are companies in which the investor has a significant influence but does not hold control. Investments in these companies are initially recognized at cost of acquisition and subsequently accounted for using the equity method. Investments in associates and joint ventures include the goodwill identified upon acquisition, net of any cumulative impairment loss. II – Joint arrangements ITAÚ UNIBANCO HOLDING defines a joint arrangements when it is entitled to rights and obligations for liabilities related to the business. ITAÚ UNIBANCO HOLDING’s share in profits or losses of its associates and joint ventures after acquisition is recognized in the Consolidated statement of income. Its share of the changes in the share in OCI of corresponding stockholders’ equity of its associates and joint ventures is recognized in its own reserves of stockholders’ equity. The cumulative changes after acquisition are adjusted against the carrying amount of the investment. When the ITAÚ UNIBANCO HOLDING share of losses of an associates and joint ventures is equal or above its interest in the associates and joint ventures, including any other receivables, ITAÚ UNIBANCO HOLDING does not recognize additional losses, unless it has incurred any obligations or made payments on behalf of the associates and joint ventures. Unrealized profits on transactions between ITAÚ UNIBANCO HOLDING and its associates and joint ventures are eliminated to the extent of the interest of ITAÚ UNIBANCO HOLDING. Unrealized losses are also eliminated, unless the transaction provides evidence of impairment of the transferred asset. The accounting policies on associates and joint ventures are consistent with the policies adopted by ITAÚ UNIBANCO HOLDING. Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 32

If the interest in the associates and joint ventures decreases, but ITAÚ UNIBANCO HOLDING retains significant influence or joint control, only the proportional amount of the previously recognized amounts in Other comprehensive income is reclassified in Income, when appropriate. f) Commitments as lessee operations ITAÚ UNIBANCO HOLDING leases mainly real estate properties (underlying assets) to carry out its business activities. The ignition recognition occurs when the agreement is signed, in the heading Other Liabilities, which corresponds to the total future payments at present value as a contra entry to the Right- of-Use Assets, depreciated under the straight-line method for the lease term and tested half-yearly to identify possible impairment losses. The financial expense corresponding to interest on lease liabilities is recognized in the heading Interest and Similar Expense in the Consolidated Statement of Income. g) Fixed assets Fixed assets are recognized at cost of acquisition less accumulated depreciation, and adjusted for impairment, if applicable. Depreciation is calculated using the straight-line method and rates based on the estimated useful lives of these assets. These rates and other information are presented in Note 13. The residual values and useful lives of assets are reviewed and adjusted, if appropriate, at the end of each period. ITAÚ UNIBANCO HOLDING reviews its assets in order to identify whether any indications of impairment exist. The recoverable amount of an asset is defined as the higher of its fair value less costs to sell and its value in use. For purposes of assessing impairment, assets are grouped at the lowest level for which independent cash flows can be identified (cash-generating units). The assessment may be made at an individual asset level when the fair value less the cost to sell may be reliably determined. Gains and losses on disposals of fixed assets are recognized in the Consolidated statement of income under Other income or General and administrative expenses. h) Intangible assets Intangible assets are non-physical assets, including software and other assets, and are initially recognized at cost. Intangible assets are recognized when they arise from legal or contractual rights, their costs can be reliably measured, and in the case of intangible assets not arising from separate acquisitions or business combinations, it is probable that future economic benefits may arise from their use. The balance of intangible assets refers to acquired assets or those internally generated. Intangible assets may have finite or indefinite useful lives. Intangible assets with finite useful lives are amortized using the straight-line method over their estimated useful lives. Intangible assets with indefinite useful lives are not amortized, but periodically tested in order to identify any impairment. ITAÚ UNIBANCO HOLDING semi-annually assesses its intangible assets in order to identify whether any indications of impairment exist, as well as possible reversal of previous impairment losses. If such indications are found, intangible assets are tested for impairment. The recoverable amount of an asset is defined as the higher of its fair value less costs to sell and its value in use. For purposes of assessing impairment, assets are grouped at the lowest level for which independent cash flows can be identified (cash-generating units). The assessment may be made at an individual asset level when the fair value less the cost to sell may be reliably determined. ITAÚ UNIBANCO HOLDING elected the cost model to measure its intangible assets after its initial recognition.

The breakdown of intangible assets is described in Note 14. i) Assets held for sale Assets held for sale are recognized in the consolidated balance sheet under the line Other assets when they are actually repossessed or there is intention to sell. These assets are initially recorded at the lower of: (i) the fair value of the asset less the estimated selling expenses, or (ii) the carrying amount of the related asset held for sale. j) Income tax and social contribution There are two components of the provision for income tax and social contribution: current and deferred. Current income tax expense approximates taxes to be paid or recovered for the applicable period. Deferred income tax and social contribution, represented by deferred tax assets and liabilities, are obtained based on the differences between the tax bases of assets and liabilities and the amounts reported in the financial statements at each year end. Income tax and social contribution expense is recognized in the Consolidated statement of income under Income tax and social contribution, except when it refers to items directly recognized in Other comprehensive income, such as: tax on fair value of financial assets measured at fair value through other comprehensive income, post-employment benefits and tax on cash flow hedges and hedge of net investment in foreign operations. Subsequently, these items are recognized in income in the realization of gain/loss of instruments. Changes in tax legislation and rates are recognized in the Consolidated statement of income in the period in which they are enacted. Interest and fines are recognized in the Consolidated statement of income under General and administrative expenses. To determine the proper level of provisions for taxes to be maintained for uncertain tax positions, a approach was applied, according to which a tax benefit is recognized if it is more likely than not that a position can be sustained, following assumptions of recognition, detailed item 2.4 n. k) Insurance contracts and private pension Insurance contracts are contracts under which ITAÚ UNIBANCO HOLDING accepts a significant insurance risk of the counterparty, by agreeing to compensate it if a specified uncertain future event adversely affects it. An insurance risk is significant only if the insurance event could cause ITAÚ UNIBANCO HOLDING to pay significant additional benefits in any scenario, except for those that do not have commercial substance. Additional benefits refer to amounts that exceed those that would be payable if no insured event occurred. At the time of the first-time adoption of IFRS, ITAÚ UNIBANCO HOLDING decided not to change its accounting policies for insurance contracts, which follow the accounting practices generally accepted in Brazil (“BRGAAP”). Although investment agreements with discretionary participation characteristics are financial instruments, they are treated as insurance contracts, as established by IFRS 4, as well as those transferring a significant financial risk. Once the contract is classified as an insurance contract, it remains as such until the end of its life, even if the insurance risk is significantly reduced during such period, unless all rights and obligations are extinguished or expired. Note 27 presents a detailed description of all products classified as insurance contracts. Private pension plans Contracts that contemplate retirement benefits after an accumulation period (known as PGBL, VGBL and FGB) assure, at the commencement date of the contract, the basis for calculating the retirement benefit (mortality table and minimum interest). The contracts specify the annuity fees and, therefore, the contract transfers the insurance risk to the issuer at the commencement date, and they are classified as insurance contracts.

Insurance premiums Insurance premiums are recognized by issuing an insurance policy or over the period of the contracts in proportion to the amount of the insurance coverage. If there is evidence of impairment losses with respect to receivables for insurance premiums, ITAÚ UNIBANCO HOLDING recognizes a provision, sufficient to cover this loss, based on the risk analysis of realization of insurance premiums receivable with installments overdue for over 60 days. Reinsurance In the ordinary course of business, ITAÚ UNIBANCO HOLDING reinsures a portion of the risks underwritten, particularly property and casualty risks that exceed the maximum limits of responsibility that we determine to be appropriate for each segment and product (after a study which considers size, experience, specificities, and the necessary capital to support these limits). These reinsurance agreements allow the recovery of a portion of the losses from the reinsurer, although they do not release the insurer from the main obligation as direct insurer of the risks contemplated in the reinsurance. O ITAÚ UNIBANCO HOLDING basically holds non-proportional contracts, which transfer part of responsibility to the reinsurance company for losses that will materialize after a certain level of claims in the portfolio. Reinsurance premiums of these contracts are accounted for under Other Assets, according to contractual effectiveness. If there is any evidence of impairment loss, ITAÚ UNIBANCO HOLDING recognizes a provision when the default period exceeds 180 days as from the credit record related to refund of claims paid. Acquisition costs Acquisition costs include direct and indirect costs related to the origination of insurance. These costs and recorded directly in result as incurred, expect for deferred acquisition costs (commissions paid for brokerage services, agency and prospecting efforts), which are recorded proportionally to the recognition of premium revenues, i.e. for the term corresponding to the insurance contract. Insurance Contract Liabilities Reserves for claims are established based on historical experience, claims in process of payment, estimated amounts of claims incurred but not yet reported, and other factors relevant to the required reserve levels. Liability Adequacy Test ITAÚ UNIBANCO HOLDING conducts the liability adequacy test by adopting current actuarial assumptions for future cash flows of all insurance contracts in force at the balance sheet date. Should the analysis show insufficiency, any deficiency identified will be accounted for in income for the period. The assumptions used to conduct the liability adequacy test are detailed in Note 27. l) Post-employments benefits ITAÚ UNIBANCO HOLDING sponsors Defined Benefit Plans and Defined Contribution Plans, accounted for in accordance with IAS 19 – Benefits to Employees. ITAÚ UNIBANCO HOLDING is required to make contributions to government social security and labor indemnity plans, in Brazil and in other countries where it operates.

Pension plans - Defined benefit plans The liability or asset, as the case, is recognized in the Consolidated Balance Sheet with respect to the defined benefit plan corresponds to the present value of defined benefit obligations at the balance sheet date less the fair value of plan assets. Defined benefit obligations are calculated on a yearly basis by an independent actuarial advisor based on the projected unit credit method. Pension plans - defined contribution For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING, through pension plan funds, are recognized as a liabilities as a contra entry to expense, when due. If contributions made exceed the liability for a service provided, it will be accounted for as an asset recognized at fair value, and possible remeasurements are recognized in Other Comprehensive Income, in the period they occur. Other post-employment benefit obligations Likewise the defined benefit pension plans, these obligations are assessed annually by independent and qualified actuaries, and costs expected from these benefits are accumulated during the employment period and gains and losses arising from adjustments of practices and changes in actuarial assumptions are recognized in Stockholders’ equity, under Other comprehensive income, in the period they occurred. m) Share-based payment Share-based payments are accounted for in accordance with the amount of equity instruments granted, and they may be shares or stock options according to the plan, based on their fair value at the grant date. This cost is recognized during the vesting period of the right to exercise the instruments. The total amount to be expensed is determined by reference to the fair value of equity instruments excluding the impact of any service and non-market performance vesting conditions (notably remaining an employee of the entity over a specified time period). n) Provisions, contingent assets and contingent liabilities Contingent assets and liabilities are potential rights and obligations arising from past events for which materialization depends on uncertain future events. Contingent assets are not recognized in the Consolidated Financial Statements, except when the Management of ITAÚ UNIBANCO HOLDING understands that realization is virtually certain, which generally corresponds to lawsuits with favorable rulings, in final and unappealable judgments, withdrawal from lawsuits as a result of a payment in settlement or as a result of an agreement to offset against an existing liability. These contingencies are evaluated based on Management’s best estimates, and are classified as: · Probable: in which liabilities are recognized in the consolidated balance sheet under Provisions; · Possible: which are disclosed in the Consolidated Financial Statements, but no provision is recorded; · Remote: which require neither a provision nor disclosure. The amount of court escrow deposits is adjusted in accordance with current legislation. o) Capital Common and preferred shares, which are equivalent to common shares but without voting rights are classified in Stockholders’ equity. The additional costs directly attributable to the issue of new shares are included in Stockholders’ equity as a deduction from the proceeds, net of taxes.

Other post-employment benefit obligations Likewise the defined benefit pension plans, these obligations are assessed annually by independent and qualified actuaries, and costs expected from these benefits are accumulated during the employment period and gains and losses arising from adjustments of practices and changes in actuarial assumptions are recognized in Stockholders’ equity, under Other comprehensive income, in the period they occurred. m) Share-based payment Share-based payments are accounted for in accordance with the amount of equity instruments granted, and they may be shares or stock options according to the plan, based on their fair value at the grant date. This cost is recognized during the vesting period of the right to exercise the instruments. The total amount to be expensed is determined by reference to the fair value of equity instruments excluding the impact of any service and non-market performance vesting conditions (notably remaining an employee of the entity over a specified time period). n) Provisions, contingent assets and contingent liabilities Contingent assets and liabilities are potential rights and obligations arising from past events for which materialization depends on uncertain future events. Contingent assets are not recognized in the Consolidated Financial Statements, except when the Management of ITAÚ UNIBANCO HOLDING understands that realization is virtually certain, which generally corresponds to lawsuits with favorable rulings, in final and unappealable judgments, withdrawal from lawsuits as a result of a payment in settlement or as a result of an agreement to offset against an existing liability. These contingencies are evaluated based on Management’s best estimates, and are classified as: · Probable: in which liabilities are recognized in the consolidated balance sheet under Provisions; · Possible: which are disclosed in the Consolidated Financial Statements, but no provision is recorded; · Remote: which require neither a provision nor disclosure. The amount of court escrow deposits is adjusted in accordance with current legislation. o) Capital Common and preferred shares, which are equivalent to common shares but without voting rights are classified in Stockholders’ equity. The additional costs directly attributable to the issue of new shares are included in Stockholders’ equity as a deduction from the proceeds, net of taxes.

Note 6 – Derivatives ITAÚ UNIBANCO HOLDING enters into derivative financial instruments with various counterparties to manage its overall exposures and to assist its customers in managing their own exposures. Futures – Interest rate and foreign currency futures contracts are commitments to buy or sell a financial instrument at a future date, at a contracted price or yield and may be settled in cash or through delivery. The notional amount represents the face value of the underlying instrument. Commodity futures contracts or financial instruments are commitments to buy or sell commodities (mainly gold, coffee and orange juice), at a future date, at a contracted price, which are settled in cash. The notional amount represents the quantity of such commodities multiplied by the future price at the contract date. Daily cash settlements of price movements are made for all instruments. Forwards – Interest forward contracts are agreements to exchange payments on a specified future date, based on a market change in interest rates from trade date to contract settlement date. Foreign exchange forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed price, at an agreed settlement date. Financial instrument forward contracts are commitments to buy or sell a financial instrument on a future date at a contracted price and are settled in cash. Swaps – Interest rate and foreign exchange swap contracts are commitments to settle in cash at a future date or dates, based on differentials between specified financial indices (either two different interest rates in a single currency or two different rates each in a different currency), as applied to a notional principal amount. Swap contracts presented in Other in the table below correspond substantially to inflation rate swap contracts. Options – Option contracts give the purchaser, for a fee, the right, but not the obligation, to buy or sell within a limited time a financial instrument including a flow of interest, foreign currencies, commodities, or financial instruments at a contracted price that may also be settled in cash, based on differentials between specific indices. Credit Derivatives – Credit derivatives are financial instruments with value relating to the credit risk associated to the debt issued by a third party (the reference entity), which permits that one party (the purchaser of the hedge) transfers the risk to the counterparty (the seller of the hedge). The seller of the hedge should make payments as set forth in the contract when the reference entity undergoes a credit event, such as bankruptcy, default or debt restructuring. The seller of the hedge receives a premium for the hedge, but, on the other hand, assumes the risk that the underlying asset referenced in the contract undergoes a credit event, and the seller would have to make the payment to the purchaser of the hedge, which could be the notional amount of the credit derivative. The total value of margins pledged in guarantee by ITAÚ UNIBANCO HOLDING was R$ 12,867 (R$ 12,855 at 12/31/2018) and was basically comprised of government securities.

Commodity futures contracts or financial instruments are commitments to buy or sell commodities (mainly gold, coffee and orange juice), at a future date, at a contracted price, which are settled in cash. The notional amount represents the quantity of such commodities multiplied by the future price at the contract date. Daily cash settlements of price movements are made for all instruments. Forwards – Interest forward contracts are agreements to exchange payments on a specified future date, based on a market change in interest rates from trade date to contract settlement date. Foreign exchange forward contracts represent agreements to exchange the currency of one country for the currency of another country at an agreed price, at an agreed settlement date. Financial instrument forward contracts are commitments to buy or sell a financial instrument on a future date at a contracted price and are settled in cash. Swaps – Interest rate and foreign exchange swap contracts are commitments to settle in cash at a future date or dates, based on differentials between specified financial indices (either two different interest rates in a single currency or two different rates each in a different currency), as applied to a notional principal amount. Swap contracts presented in Other in the table below correspond substantially to inflation rate swap contracts. Options – Option contracts give the purchaser, for a fee, the right, but not the obligation, to buy or sell within a limited time a financial instrument including a flow of interest, foreign currencies, commodities, or financial instruments at a contracted price that may also be settled in cash, based on differentials between specific indices. Credit Derivatives – Credit derivatives are financial instruments with value relating to the credit risk associated to the debt issued by a third party (the reference entity), which permits that one party (the purchaser of the hedge) transfers the risk to the counterparty (the seller of the hedge). The seller of the hedge should make payments as set forth in the contract when the reference entity undergoes a credit event, such as bankruptcy, default or debt restructuring. The seller of the hedge receives a premium for the hedge, but, on the other hand, assumes the risk that the underlying asset referenced in the contract undergoes a credit event, and the seller would have to make the payment to the purchaser of the hedge, which could be the notional amount of the credit derivative. The total value of margins pledged in guarantee by ITAÚ UNIBANCO HOLDING was R$ 12,867 (R$ 12,855 at 12/31/2018) and was basically comprised of government securities.

IV - Credit derivatives ITAÚ UNIBANCO HOLDING buys and sells credit protection in order to meet the needs of its customers, management and mitigation of its portfolios' risk. CDS (credit default swap) is credit derivative in which, upon a default related to the reference entity, the protection buyer is entitled to receive, from the protection seller, the amount equivalent to the difference between the face value of the CDS contract and the fair value of the liability on the date the contract was settled, also known as the recovered amount. The protection buyer does not need to hold the debt instrument of the reference entity for it to receive the amounts due pursuant to the CDS contract terms when a credit event occurs. TRS (total return swap) is a transaction in which a party swaps the total return of an asset or of a basket of assets for regular cash flows, usually interest and a guarantee against capital loss. In a TRS contract, the parties do not transfer the ownership of the assets. 03/31/2019 Maximum potential From 1 to 3 From 3 to 5 of future payments, Before 1 year Over 5 years years years gross By instrument CDS 6,544 1,124 2,107 3,146 167 Total by instrument 6,544 1,124 2,107 3,146 167 By risk rating Investment grade 2,388 309 522 1,431 126 Below investment grade 4,156 815 1,585 1,715 41 Total by risk 6,544 1,124 2,107 3,146 167 By reference entity Brazilian government 3,008 674 1,153 1,162 19 Government – abroad 1,052 92 112 798 50 Private entities 2,484 358 842 1,186 98 Total by entity 6,544 1,124 2,107 3,146 167 12/31/2018 Maximum potential From 1 to 3 From 3 to 5 of future payments, Before 1 year Over 5 years years years gross By instrument CDS 6,853 1,685 1,913 3,203 52 Total by instrument 6,853 1,685 1,913 3,203 52 By risk rating Investment grade 1,361 300 510 539 12 Below investment grade 5,492 1,385 1,403 2,664 40 Total by risk 6,853 1,685 1,913 3,203 52 By reference entity Brazilian government 3,772 1,167 1,118 1,487 - Government – abroad 314 71 85 156 2 Private entities 2,767 447 710 1,560 50 Total by entity 6,853 1,685 1,913 3,203 52 ITAÚ UNIBANCO HOLDING assesses the risk of a credit derivative based on the credit ratings attributed to the reference entity by independent credit rating agencies.

Note 7 – Hedge accounting There are three types of hedge relations: Fair value hedge, Cash flow hedge, and Hedge of net investment in foreign operations. In hedge accounting, the groups of risk factors measured by ITAÚ UNIBANCO HOLDING are: · Interest Rate: Risk of loss in transactions subject to interest rate variations; · Currency: Risk of loss in transactions subject to exchange variation. The structure of risk limits is extended to the risk factor level, with specific limits that aim at improving the monitoring and understanding process, as well as avoiding concentration of these risks. The structures designed for categories of interest rate and exchange rate are realized considering aggregate risks when there are compatible hedge instruments. Due to a management’s decision, in certain cases risks are hedged for the term and limit of the hedge instrument risk factor. The other risk factors hedged by the institution are presented in Note 32. To protect cash flows and fair value of instruments designated as hedged items, ITAÚ UNIBANCO HOLDING uses derivative financial instruments and financial assets. Currently, Futures Contracts, Options, NDF (non- deliverable forward), Forward, Swap and Financial Assets are used. ITAÚ UNIBANCO HOLDING manages risks through the economic relationship between hedge instruments and hedged items, where the expectation is that these instruments move in opposite directions and in the same proportion, with the purpose of neutralizing risk factors. The designated coverage ratio is always 100% of the risk factor eligible for coverage. The sources of ineffectiveness are in general related to the counterparty’s credit risk and possible mismatches of terms between the hedge instrument and the hedged item. a) Cash flow hedge The cash flow hedge strategies of ITAÚ UNIBANCO HOLDING consist of a hedge of exposure to variations in cash flows, payment of interest and exposure to interest rate, which are attributable to changes in interest rates related to assets and liabilities recognized and changes in interest rates of unrecognized assets and liabilities. ITAÚ UNIBANCO HOLDING has applied cash flow hedge strategies as follows: Interest rate risks · Hedge of time deposits and repurchase agreements: to hedge of the variability in cash flows of interest payments resulting from changes in the DI interest rate, through futures contracts; · Hedge of asset transactions: to hedge the variations in cash flows of interest receipts resulting from changes in the DI rate, through futures contracts; · Hedge of assets denominated in UF*: to hedge the variations in cash flows of interest receipts resulting from changes in the UF*, through swap contracts; · Hedge of Funding: to hedge the variations in cash flows of interest payments resulting from changes in the TPM* rate and foreign exchange, through swap contracts; · Hedge of loan operations: to hedge the variations in cash flows of interest receipts resulting from changes in the TPM* rate, through swap contracts; · Hedge of asset-backed securities under repurchase agreements: to hedge changes in cash flows from interest received on changes in Selic (benchmark interest rate), through futures contracts. *UF – Chilean unit of account / TPM – Monetary policy rate ITAÚ UNIBANCO HOLDING does not use the qualitative method to evaluate the effectiveness and to measure the ineffectiveness of such strategies. In such strategies of cash flow hedge, ITAÚ UNIBANCO HOLDING uses the hypothetical derivative method. The hypothetical derivative method is based on a comparison of the change in the fair value of a hypothetical derivative with terms identical to the critical terms of the variable-rate liability, and this change in the fair value of a hypothetical derivative is considered a proxy of the present value of the cumulative change in the future cash flow expected for the hedged liability.

b) Hedge of net investment in foreign operations ITAÚ UNIBANCO HOLDING strategies of net investments in foreign operations consist of a hedge of the exposure in foreign currency arising from the functional currency of the foreign operation, with respect to the functional currency of the head office, by contracting futures, DDI, NDF and financial assets. The risk hedged in this type of strategy is the foreign exchange risk. ITAÚ UNIBANCO HOLDING does not use the qualitative method to assess the effectiveness and measure the ineffectiveness of these strategies. To evaluate the effectiveness and to measure the ineffectiveness of such strategies, ITAÚ UNIBANCO HOLDING uses the Dollar Offset Method. The Dollar Offset Method is based on a comparison of the change in fair value (cash flow) of the hedge instrument, attributable to changes in exchange rate and gain (loss) arising from the variation in exchange rates, on the amount of investment abroad designated as a hedged item. 03/31/2019 Hedged item Hedge instrument (2) Variation in the Book Value Strategies Variation in value Foreign currency Nominal amounts used to recognized in Other convertion Value calculate hedge Assets Liabilities comprehensive income ineffectiveness Foreign exchange risk (1) Hedge of net investment in foreign operations - 15,010 (7,574) (7,574) 12,646 (7,570) Total - 15,010 (7,574) (7,574) 12,646 (7,570) 12/31/2018 Hedged item Hedge instrument (2) Variation in the Book Value Strategies Variation in value Foreign currency Nominal amounts used to recognized in Other convertion Value calculate hedge Assets Liabilities comprehensive income ineffectiveness Foreign exchange risk (1) Hedge of net investment in foreign operations - 14,820 (7,300) (7,300) 12,550 (7,296) Total - 14,820 (7,300) (7,300) 12,550 (7,296) (1) Hedge instruments include the overhedge rate of 44.65% regarding taxes.

ITAÚ UNIBANCO HOLDING does not use the qualitative method to assess the effectiveness and measure the ineffectiveness of these strategies. To evaluate the effectiveness and to measure the ineffectiveness of such strategies, ITAÚ UNIBANCO HOLDING uses the Dollar Offset Method. The Dollar Offset Method is based on a comparison of the change in fair value (cash flow) of the hedge instrument, attributable to changes in exchange rate and gain (loss) arising from the variation in exchange rates, on the amount of investment abroad designated as a hedged item. 03/31/2019 Hedged item Hedge instrument (2) Variation in the Book Value Strategies Variation in value Foreign currency Nominal amounts used to recognized in Other convertion Value calculate hedge Assets Liabilities comprehensive income ineffectiveness Foreign exchange risk (1) Hedge of net investment in foreign operations - 15,010 (7,574) (7,574) 12,646 (7,570) Total - 15,010 (7,574) (7,574) 12,646 (7,570) 12/31/2018 Hedged item Hedge instrument (2) Variation in the Book Value Strategies Variation in value Foreign currency Nominal amounts used to recognized in Other convertion Value calculate hedge Assets Liabilities comprehensive income ineffectiveness Foreign exchange risk (1) Hedge of net investment in foreign operations - 14,820 (7,300) (7,300) 12,550 (7,296) Total - 14,820 (7,300) (7,300) 12,550 (7,296) (1) Hedge instruments include the overhedge rate of 44.65% regarding taxes.

c) Fair value hedge The fair value hedge strategy of ITAÚ UNIBANCO HOLDING consists in hedging the exposure to variation in fair value, in the receipt and payment of interest related to recognized assets and liabilities. ITAÚ UNIBANCO HOLDING has applied fair value hedge as follows: Interest rate risk: · To protect the risk of variation in the fair value of receipt and payment of interest resulting from variations in the fair value of variable rates involved, by contracting swaps and futures. ITAÚ UNIBANCO HOLDING does not use the qualitative method to assess effectiveness and to measure ineffectiveness of these strategies. To evaluate the effectiveness and to measure the ineffectiveness of such strategy, ITAÚ UNIBANCO HOLDING uses the percentage approach and dollar offset method: · The percentage approach is based on the calculation of change in the fair value of the reviewed estimate for the hedged position (hedge item) attributable to the protected risk versus the change in the fair value of the hedged derivative instrument. · The dollar offset method is calculated based on the difference between the variation of the fair value of the hedging instrument and the variation in the fair value of the hedged item attributed to changes in the interest rate.

a) Main Actuarial Assumptions Actuarial assumptions of demographic and financial nature should reflect the best estimated about the variables that determine the post-employment benefit amounts. The main demographic assumptions comprise: mortality table and turnover of active participants and the main financial assumptions include: discount rate, future salary increases, growth of plan benefits and inflation. 03/31/2019 03/31/2018 (1) Discount rate 9.72% p.a. 9.98% p.a.

Actuarial method Projected Unit Credit Projected Unit Credit (1) Determined based on market yield related to National Treasury Notes (NTN-B) and compatible with the economic scenario observed on the balance sheet closing date, considering the volatility of interest market and models used. (2) Correspond to those disclosed by SOA – Society of Actuaries , that reflect a 10% increase in the probabilities of survival regarding the respective basic tables. (3) Updated to the new expectation of mass behavior. Retired plans sponsored by foreign subsidiaries - Banco Itaú (Suisse) S.A., Itaú CorpBanca Colombia S.A. and PROSERV - Promociones y Servicios S.A. de C.V. - are structured as Defined Benefit modality and adopt actual assumptions adequate to masses of participants and the economic scenario of each country. b) Risk Management The EFPCs sponsored by ITAÚ UNIBANCO HOLDING are regulated by the National Council for Complementary Pension (CNPC) and PREVIC, has an Executive Board, Advisory and Tax Councils. Benefits offered have long-tem characteristics and the main factors involved in the management and measurement of their risks are financial risk, inflation risk and biometric risk. - Financial Risk – the actuarial liability is calculated by adopting a discount rate different from rates earned in investments. If real income from plan investments is lower than yield expected, this may give rise to a deficit. To mitigate this risk and assure the capacity to pay long-term benefits, the plans have a significant percentage of fixed-income securities pegged to the plan commitments, aiming at minimizing volatility and risk of mismatch between assets and liabilities. - Inflation risk – a large part of liabilities is pegged to inflation risk, making actuarial liabilities sensitive to increase in rates. To mitigate this risk, the same financial risks mitigation strategies are used. - Demographic Risk – plans that have any obligation actuarially assessed are exposed to biometric risk. In the event the mortality tables used are not adherent to the mass of plan participants, a deficit or surplus may arise in actuarial evaluation. To mitigate this risk, adherence tests to biometric assumptions are conducted to ensure their adequacy to liabilities of respective plans. For purposes of registering in the balance sheet the EFPCs that manage them, actuarial liabilities of plans use discount rate adherent to its asset portfolio and income and expense flows, according to a study preparedby an independent consulting company. The actuarial method used is the aggregate method, through which the plan costing Is defined by the difference between its equity coverage and the current value of its future liabilities. Observing the methodology established in the respective actuarial technical note. In the event deficit is verified in the concession period above the settlement limits set forth by the legislation in force, a debt agreement is entered into with the sponsor with financial guarantees.

Its costing is actuarially determined so as to ensure coverage maintenance. These plans are closed to new adhesions. Assumptions for discount rate, inflation, mortality table and actuarial method are the same used for retirement plans. In the last 3 years, ITAÚ UNIBANCO HOLDING used the percentage of 8.16% p.a. for medical inflation and the percentage of 3% p.a. for aging factor. Particularly in other post-employment benefits, there is medical inflation risk associated to increase in medical costs above expectation.

VII - Liability Adequacy Test The ITAÚ UNIBANCO HOLDING carry out the Liability Adequacy Test, comparing the amount recognized for its technical reserves with the current estimate of cash flow of its future obligations. The estimate should consider all cash flows related to the business, which is the minimum requirement for carrying out the adequacy test. The Liability Adequacy Test did not indicate significant insufficiency in the reporting periods 2018 and 2017. The assumptions used in the test are periodically reviewed and are based on the best practices and the analysis of subsidiaries’ experience, therefore representing the best estimates for cash flow projections. Methodology and test grouping Specifically for insurance products, cash flows were projected using the method known as run-off triangle of quarterly frequency. For social security products, cash flows for the deferral and assignment phases are tested on a separate basis. The risk grouping criterion considers groups subject to similar risks that are jointly managed as a single portfolio. Biometric tables Biometric tables are instruments to measure the biometric risk represented by the probability of death, survival or disability of a participant. For death and survival estimates, the Brazilian Market Insurer Experience (BR-EMS) tables in effect are used, adjusted according to life expectancy development of Scale G, and the Álvaro Vindas table is adopted to estimate benefit requests for disability. Risk-free interest rate The relevant risk-free forward interest-rate structure is an indicator of the pure time value of money used to price the set of projected cash flows. The relevant structure of risk-free interest rate was obtained from the curve of securities deemed to be credit risk free, available in the Brazilian financial market and determined pursuant to an internal policy of ITAÚ UNIBANCO HOLDING, considering the addition of spread, which took into account the impact of the market result of Financial assets at amortized cost of the guarantee assets portfolio. Income conversion rate The income conversion rate represents the expected conversion of balances accumulated by participants in retirement benefits. The decision of conversion into income by participants is influenced by behavioral, economic and tax factors. Other assumptions Related expenses, cancellations and partial redemptions, future increases and contributions, among others, are assumptions that affect the estimate of projected cash flows since they represent expenses and income arising from insurance agreements assumed.

The methods and assumptions adopted to estimate the fair value are defined below: a) Cash and deposits on demand, Central Bank compulsory deposits, Securities purchased under agreements to resell, Securities sold under repurchase agreements – The carrying amounts for these instruments approximate their fair values. b) Interbank deposits, Deposits, Interbank and Institutional Market Funds – they are calculated by discounting estimated cash flows at market interest rates. c) Securities and Derivatives - Under usual conditions, the prices quoted in the market are the best indicators of fair values of these financial instruments. However, not all instruments have liquidity or quoted market prices and, in such cases, it is necessary to adopt present value estimates and other techniques to establish their fair value. In the absence of the prices quoted by the Brazilian Association of Entities from Financial and Capital Markets (ANBIMA), the fair values of government securities are determined based on the interest rates provided by brokers. The fair values of corporate debt securities are calculated by discounting estimated cash flows at market interest rates. The fair values of shares are computed based on their prices quoted in the market. The fair values of derivative financial instruments were determined as follows: · Swaps: The cash flows are discounted to present value based on yield curves that reflect the appropriate risk factors drawn mainly based on the exchange price of derivatives at B3, of Brazilian government securities in the secondary market or derivatives and securities traded abroad. These yield curves may be used to obtain the fair value of currency swaps, interest rate swaps and swaps based on other risk factors (commodities, stock exchange indices, etc.). · Futures and forwards: Quotations on exchanges or criteria identical to those applied to swaps. · Options: determined based on mathematical models, such as Black & Scholes, using data, in general from Bloomberg, of implicit volatility, interest rate yield curve and fair value of the underlying asset. Current market prices of options are used to compute the implicit volatilities. · Loans: They are inversely related to the probability of default (PD) in a financial instrument subject to credit risk. The process of adjusting the market price of these spreads is based on the differences between the yield curves with and without credit risk. d) Loan operations and lease operations – Fair value is estimated based on groups of loans with similar financial and risk characteristics, using valuation models. The fair value of fixed-rate loans was determined by discounting estimated cash flows, applying current interest rates for similar loans. For the majority of loans at floating rate, the carrying amount was considered close to their fair value. The fair value of loan and lease operations not overdue was calculated by discounting the expected payments of principal and interest through maturity. The fair value of overdue loan and lease transactions was based on the discount of estimated cash flows, using a rate proportional to the risk associated with the estimated cash flows, or on the underlying collateral. The assumptions related to cash flows and discount rates are determined using information available in the market and the borrower’s specific information of the debtor. e) Other financial assets / liabilities – primarily composed of receivables from credit card issuers, deposits in guarantee for contingent liabilities, provisions and legal obligations and trading and intermediation of securities. The carrying amounts for these assets/liabilities substantially approximate their fair values, since they principally represent amounts to be received in the short term from credit card holders and to be paid to credit card acquirers, judicially required deposits (indexed to market rates) made by ITAÚ UNIBANCO HOLDING as guarantees for lawsuits or very short-term receivables (generally with a maturity of approximately 5 (five) business days). All of these items represent assets / liabilities without significant associated market, credit and liquidity risks. Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. An active market is a market in which transactions for the asset or liability being measured occur often enough and with sufficient volume to provide pricing information on an ongoing basis.

Level 2: Information that is observable for the asset or liability either directly or indirectly. Level 2 generally includes: (i) quoted prices for similar assets or liabilities in active markets; (ii) quoted prices for identical or similar assets or liabilities in markets that are not active, that is, markets in which there are few transactions for the asset or liability, the prices are not current, or quoted prices vary substantially either over time or among market makers, or in which little information is released publicly; (iii) inputs other than quoted prices that are observable for the asset or liability (for example, interest rates and yield curves observable at commonly quoted intervals, volatilities, etc.); (iv) inputs that are mainly derived from or corroborated by observable market data through correlation or by other means. Level 3: Inputs are unobservable for the asset or liability. Unobservable information shall be used to measure fair value to the extent that observable information is not available, thus allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. Financial assets at fair value through profit or loss, including Derivatives, and at fair value through other comprehensive income: Level 1: Highly-liquid securities with prices available in an active market and derivatives traded on stock exchanges. This classification level includes most of the Brazilian government securities, other foreign government securities, shares and debentures traded on stock exchanges and other securities traded in an active market. Level 2: When the pricing information is not available for a specific security, the assessment is usually based on prices quoted in the market for similar instruments, pricing information obtained for pricing services, such as Bloomberg, Reuters and brokers (only when the prices represent actual transactions) or discounted cash flows, which use information for assets actively traded in an active market. These securities are classified into Level 2 of the fair value hierarchy and are comprised of certain Brazilian government securities, debentures, some government securities quoted in a less-liquid market in relation to those classified into Level 1, and some share prices in investment funds. Derivatives included in Level 2 are credit default swaps, cross-currency swaps, interest rate swaps, simple options and certain forwards, since information adopted by pricing models are immediately observable in actively quoted markets. The models used for these instruments are Black & Scholes, Garman & Kohlhagen, Monte Carlo and discounted cash flow. ITAÚ UNIBANCO HOLDING does not hold positions in alternative investment funds or private equity funds. Level 3: When no pricing information in an active market, ITAÚ UNIBANCO HOLDING uses internally developed models, from curves generated according to the proprietary model. The Level 3 classification includes some Brazilian government and private securities falling due after 2025 and securities that are not usually traded in an active market. Derivatives with fair values classified into Level 3 of the fair value hierarchy are composed of exotic options, certain swaps indexed to non-observable information, and swaps with other products, such as swap with option and target flow, credit derivatives and futures of certain commodities. All aforementioned methodologies may result in a fair value that may not be indicative of the net realizable value or future fair values. However, ITAÚ UNIBANCO HOLDING believes that all methodologies used are appropriate and consistent with the other market participants. However, the adoption of other methodologies or assumptions different than those used to estimate fair value may result in different fair value estimates at the balance sheet date.

Measurement of fair value Level 2 based on pricing services and brokers To assure that the fair value of these instruments is properly classified as Level 2, internal analysis of the information received are conducted, so as to understand the nature of the input by the service provider. Prices provided by pricing services that meet the following requirements are considered Level 2: input is immediately available, regularly distributed, provided by sources actively involved in significant markets and it is not proprietary. Of the total of R$ 51,213 in financial instruments classified as Level 2, on March 31, 2019, pricing service or brokers were used to evaluate securities at the value of R$ 19,652, substantially represented by: · Debentures: When available, we use price information for transactions recorded in the Brazilian Debenture System (SND), an electronic platform operated by B3, which provides multiple services for transactions involving debentures in the secondary market. Alternatively, prices of debentures provided by ANBIMA are used. Its methodology includes obtaining, on a daily basis, illustration and non-binding prices from a group of market players deemed to be significant. Such information is subject to statistical filters established in the methodology, with the purpose of eliminating outliers. · Global and corporate securities: The pricing process for these securities consists in capturing from 2 to 8 quotes from Bloomberg, depending on the asset. The methodology consists in comparing the highest purchase prices and the lowest sale prices of trades provided by Bloomberg for the last day of the month. Such prices are compared with information from purchase orders that the Institutional Treasury of ITAÚ UNIBANCO HOLDING. Should the difference between them be lower than 0.5%, the average price of Bloomberg is used. Should it be higher than 0.5% or if the Institutional Treasury does not provide information on this specific security, the average price gathered directly from other banks is used. The price of the Institutional Treasury is used as a reference only and never in the computation of the final price. Level 3 recurring fair value measurements The departments in charge of defining and applying the pricing models are segregated from the business areas. The models are documented, submitted to validation by an independent area and approved by a specific committee. The daily process of price capture, calculation and disclosure are periodically checked according to formally defined testing and criteria and the information is stored in a single and corporate history data base. The most recurring cases of assets classified as Level 3 are justified by the discount factors used. Factors such as the fixed interest curve in Brazilian Reais and the TR coupon curve – and, as a result, its related factors – have inputs with terms shorter than the maturities of these fixed-income assets. For swaps, the analysis is carried out by index for both parties. There are some cases in which the inputs periods are shorter than the maturity of the derivative.

Sensitivity analyses operations of Level 3 The fair value of financial instruments classified in Level 3 is measured through assessment techniques based on correlations and associated products traded in active markets, internal estimates and internal models. Significant unverifiable inputs used for measurement of the fair value of instruments classified in Level 3 are: interest rates, underlying asset prices and volatility. Significant variations in any of these inputs separately may give rise to significant changes in the fair value.

Legal liabilities arise from lawsuits filed to discuss the legality and unconstitutionality of the legislation in force, being subject to an accounting provision. I- Civil lawsuits In general, provisions and contingencies arise from claims related to the revision of contracts and compensation for damages and pain and suffering and the lawsuits are classified as follows: Collective lawsuits: Related to claims of a similar nature and with individual amounts that are not considered significant. Provisions are determined on a monthly basis and the expected amount of losses is accrued according to statistical references that take into account the nature of the lawsuit and the characteristics of the court (Small Claims Court or Regular Court). Contingencies and provisions are adjusted to reflect the amounts deposited as guarantee for their execution when realized. Individual lawsuits: Related to claims with unusual characteristics or involving significant amounts, these are periodically calculated based on the calculation of the amount claimed. The amounts considered as probable losses are recorded as provisions. ITAÚ UNIBANCO HOLDING, despite having complied with the rules in force at the time, is a defendant in lawsuits filed by individuals referring to collection of inflation adjustments to savings accounts resulting from economic plants implemented in the decades of 1980 and 1990, as well as in collective lawsuits filed by: (i) consumer protection associations; and (ii) the Public Attorney’s Office, on behalf of the savings accounts holders. ITAÚ UNIBANCO HOLDING recognizes provisions upon receipt of summons, as well as at the time individuals demand the enforcement of the decision rendered by the Judiciary power, using the same criteria adopted to determine provisions for individual lawsuits. The Federal Supreme Court (STF) has issued some decisions favorable to savings account holders, but it has not established its understanding with respect to the constitutionality of the economic plans and their applicability to savings accounts. Currently, the appeals involving these matters are suspended, as determined by the STF, until it pronounces a final decision. In December 2017, through mediation of the Federal Attorney’s Office (AGU) and supervision of the BACEN, savers (represented by two civil associations, FEBRAPO and IDEC) and FEBRABAN entered into an instrument of agreement aiming at resolving lawsuits related to economic plans, and ITAÚ UNIBANCO HOLDING has already adhered to its terms. Said agreement was approved on March 1, 2018, by the Plenary Session of the Federal Supreme Court (STF) and, savers may adhere to their terms for a 24-month period, counted as from May 22, 2018 with the subsequent conclusion of lawsuits. II- Labor claims Provisions and Contingencies arise from lawsuits in which labor rights provided for in labor legislation specific to the related profession are discussed, such as: overtime, salary equalization, reinstatement, transfer allowance, pension plan supplement, among others, are discussed. These lawsuits are classified as follows: Collective lawsuits: related to claims considered similar and with individual amounts that are not considered relevant. The expected amount of loss is determined and accrued on a monthly basis in accordance with a statistical share pricing model and is reassessed taking into account the court rulings. Provisions and contingencies are adjusted to the amounts deposited as guarantee for their execution when realized. Individual lawsuits: related to claims with unusual characteristics or involving significant amounts. These are periodically calculated based on the calculation of the amount claimed. Probability of loss which, in turn, is estimated in accordance with the actual and legal characteristics related to that lawsuit. III- Other Risks These are quantified and accrued mainly based on the evaluation of rural credit transactions with joint liability and FCVS (salary variations compensation fund) credits assigned to Banco Nacional.

Information by segment has been prepared in accordance with accounting practices adopted in Brazil and was adjusted by the items below: Allocated capital: The statements of each segment consider the capital allocation based on a proprietary model and consequent impacts on results arising from this allocation. This model comprises the following components: Credit risk, operational risk, market risk and insurance underwriting risk. Income tax rate: We consider the total income tax rate, net of the tax effect from the payment of interest on capital, for the Retail Banking, Wholesale Bank and Activities with the Market segments. The difference between the income tax amount calculated by segment and the effective income tax amount, as stated in the consolidated financial statements, is allocated to the Activities with the Market + Corporation column. · Reclassification and application of managerial criteria The managerial statement of income was used to prepare information per segment. These statements were obtained based on the statement of income adjusted by the impact of non-recurring events and the managerial reclassifications in income. The main reclassifications between the accounting and managerial results are: Banking product: Considers the opportunity cost for each operation. The financial statements were adjusted so that the stockholders' equity was replaced by funding at market price. Subsequently, the financial statements were adjusted to include revenues related to capital allocated to each segment. The cost of subordinated debt and the respective remuneration at market price were proportionally allocated to the segments, based on the economic allocated capital. Hedge tax effects: The tax effects of the hedge of investments abroad were adjusted – these were originally recorded in the tax expenses (PIS and COFINS) and Income Tax and Social Contribution on Net Income (IR and CSLL) lines – and are now reclassified to financial margin.

It also shows the financial margin with the market, the Treasury operating cost, the equity in earnings of companies not associated to each one of the segments. a) Basis of presentation Segment information is prepared based on the reports used by top management to assess the performance and to make decisions regarding the allocation of funds for investment and other purposes.

Control and capital management units, in turn, support the ITAÚ UNIBANCO HOLDING management by monitoring and analyzing risk and capital. The Board of Directors is the main body responsible for establishing guidelines, policies, and approval levels for risk and capital management. The Capital and Risk Management Committee (CGRC), in turn, is responsible for supporting the Board of Directors in the performance of its assignments related to capital and risk management.

Additionally, the institution has panels collegiate bodies, which exercise the responsibilities delegated in capital and risk management, presided over by the Executive Vice-President of the Risk and Finance Department (ARF). To support this structure, ARF has specialized executive boards to ensure, on an independent and centralized basis, that the institution’s risks and capital are managed in compliance with policies and procedures established. b) Risk Management Risk Appetite The risk appetite of ITAÚ UNIBANCO HOLDING is based on the Board of Director’s statement: “We are a universal bank, operating mainly in Latin America. Supported by our risk culture, we act with strict ethical standard and regulatory compliance, in search for high and increasing results, with low volatility, through long-lasting relationship with the client, correct risk pricing, pulverized funding and proper use of capital.” Based on this statement, five dimensions have been established, each dimension is made up of a set of metrics associated with the main risks involved, combining supplementary measurement methods, in search for a comprehensive vision of our exposures. The Board of Directors is responsible for approving guidelines and limits for risk appetite, exercising its activities with the support of CGRC and CRO - Chief Risk Officer. The limits for risk appetite are frequently monitored and reported to risk committees and to the Board of Directors, which will guide the preventive measures to be taken to ensure that exposures are aligned with the strategies of ITAÚ UNIBANCO HOLDING. The five dimensions of risk appetite are: · Capitalization: establishes that ITAÚ UNIBANCO HOLDING must have capital sufficient to face any serious recession period or a stress event without the need to adjust its capital structure under unfavorable circumstances. It is monitored through the follow-up of ITAÚ UNIBANCO HOLDING’s capital ratios, both in normal and stress scenarios, and of the ratings of the institution's debt issues. · Liquidity: establishes that the liquidity of ITAÚ UNIBANCO HOLDING must withstand long stress periods. It is monitored through the follow-up of liquidity ratios. · Composition of results: defines that business will be focused primarily in Latin America, where ITAÚ UNIBANCO HOLDING has a diversified base of clients and products, with low appetite for volatility of results and high risks. This dimension comprises aspects related to business and profitability, and market and credit risks. By adopting exposure concentration limits, such as industry sectors, counterparty quality, countries and geographical regions and risk factors, these monitored metrics seek to ensure the proper composition of portfolios, aimed at the low volatility of results and business sustainability.

For large companies, the rating is based on information such as economic and financial condition of the counterparty, their cash-generating capability, the economic group to which they belong, and the current and prospective situation of the economic sector in which they operate. The credit proposals are analyzed on a case by case basis, through an approval-level mechanism. In compliance with CMN Resolution 4,557, of February 23, 2017, the document “Public Access Report – Credit Risk“, which includes the guidelines established by the institutional credit risk control policy can be viewed at www.itau.com.br/investor-relations, under Corporate Governance, Regulations and Policies. ITAÚ UNIBANCO HOLDING strictly controls the credit exposure of clients and counterparties, taking action to address situations in which the actual exposure exceeds the desired one. For this purpose, contractually provided actions can be taken, such as early settlement or requirement of additional collateral. 1.1 Collateral and policies for mitigating credit risk ITAÚ UNIBANCO HOLDING uses guarantees to increase its capacity for recovery in operations exposed to credit risk. The guarantees may be personal, secured, legal structures with mitigating power and offset agreements. For collateral to be considered instruments that mitigate credit risk, they must comply with the requirements and standards that regulate them, be them internal or external ones, be legally valid (effective), enforceable, and assessed on a regular basis. ITAÚ UNIBANCO HOLDING also uses credit derivatives, to mitigate credit risk of its portfolios of loans and securities. These instruments are priced based on models that use the fair value of market inputs, such as credit spreads, recovery rates, correlations and interest rates. 1.2 Policy on the provision and Economic scenarios Both the credit risk and the finance areas are responsible for defining the methodologies used to measure the allowance for loan losses and for assessing changes in the provision amounts on a recurring basis. These areas monitor the trends observed in expected credit loss by segment level, in addition to establishing an initial understanding of the variables that may trigger changes in the allowance for loan losses, the probability of default or the loss given default. Once the trends have been identified and an initial assessment of the variables has been made at the corporate level, the business areas are responsible for further analyzing these observed trends at a detailed level and for each portfolio, in order to understand the underlying reasons for the trends observed and for deciding whether changes are required in the credit policies. The provisions for expected losses are recognized considering the expected risk linked to contracts with similar characteristics and in anticipation of impairment signs, considering a loss horizon adequate to the remaining period of the contract termination. For contracts of products with no determined termination date, average results of impairment and default are used to determine the loss horizon. Additionally, information on economic scenarios and public information with internally developed information are used to determine and affect the expected credit loss, adjusting loss levels to expected macroeconomic realities. 1.3 Classification of Stages of Credit Impairment ITAÚ UNIBANCO HOLDING considers clients’ internal information, statistic models, days of default, and quantitative analysis in order to determine the credit status of portfolio agreements. Rules for change of stage consider lower and higher internal ratings (quantitative criteria), in addition to a relative variation of ratings since the initial recognition. Information on days of delay, used on an absolute basis, is an important factor for the classification of stages, and after a certain credit status of the agreement is determined, the classification in one of the three stages of credit deterioration is established. Based on this classification, rules for measurement of expected credit loss determined for each stage are used, as described in Note 2.4e.

Further impairment of assets is recorded as a provision, with a corresponding charge to income. The maintenance costs of these assets are expensed as incurred. The policy for sales of these assets (assets not for use) includes periodic auctions that are announced in advance and considers that the assets cannot be held for more than one year as stipulated by the BACEN.

The market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of: (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and warnings, (iii) application, analysis and tests of stress scenarios, (iv) risk reporting for individuals responsible within the business areas, in compliance with governance of ITAÚ UNIBANCO HOLDING, (v) monitoring of actions required for adjustment of positions and/or risk levels to make them feasible, and (vi) support to the launch of new financial products with security. The National Monetary Council (CMN) has regulations that establish the segregation of exposure to market risk at least in the following categories: interest rate, exchange rate, shares and commodities. Brazilian inflation indexes are treated as a group of risk indicators and receive the same treatment given to other risk indicators. The structure of limits and warnings is in line with the Board of Directors’ guidelines, and it is reviewed and approved on an annual basis.

Management of interest rate risk in the Banking Book (IRRBB) is performed based on the following metrics: · ΔEVE: difference between the present value of sum of repricing flows instruments subject to IRRBB in a base scenario and present value of sum of repricing flows of these instruments in a scenario of shock in interest rates; · ΔNII: difference between the result of financial intermediation of instruments subject to IRRBB in a base scenario and the result of financial intermediation of these instruments in a scenario of shock in interest rates. In addition to the aforementioned risk measures, sensitivity and loss control measures are also analyzed. They comprise: · Mismatching analysis (GAPS): accumulated exposure by risk factor of cash flows expressed at market value, allocated at the maturity dates; · Sensitivity (DV01- Delta Variation): impact on the market value of cash flows, when submitted to an one annual basis point increase in the current interest rates or index rate; · Sensitivity to several risk factors (Greeks): partial derivatives of an option portfolio in relation to the prices of underlying assets, implied volatilities, interest rates and time. ITAÚ UNIBANCO HOLDING uses proprietary systems to measure the consolidated market risk.

VaR is calculated at a confidence level of 99%, historical period of 4 years (1000 business days) and a holding period of one day. In addition, in a conservative approach, VaR is calculated daily, being or not volatility-weighted, and the final VaR is the most restrictive value between both methodologies. From January 1 to March 31, 2019, the average total VaR in Historical Simulation was R$ 397.1 ou 0.29% of total stockholders’ equity (R$ 399.3 or 0.26% of total stockholders’ equity 01/01 to 12/31/2018).

Liquidity risk The institution’s possibility of not being able to efficiently meet its expected and unexpected obligations, both current and future, including those arising from the pledged guarantees, without affecting its daily operations and without incurring significant losses. The control over liquidity risk is carried out by an area independent from the business area and that is responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different horizons of time, and for monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING operates. All activities are subject to verification by the independent validation, internal control and audit areas. The liquidity management policies and respective limits are established based on prospective scenarios and top management’s guidelines. These scenarios are reviewed on a periodic basis, by analyzing the need for cash due to atypical market conditions or resulting from strategic decisions of ITAÚ UNIBANCO HOLDING.

V - Stress testing The stress test is a process of simulation of extreme economic and market conditions in the institution’s results and capital. The institution has conducted this test since 2010 aiming at assessing its solvency in plausible scenarios of a systemic crisis, as well as at identifying areas that are more susceptible to the impact of stress, and that can be subject to risk mitigation. To perform the test, macroeconomic variables for each stress scenario are estimated by the economic research department. The scenarios are established considering their relevance to the bank’s result, and the probability of occurrence, and they are submitted to the approval of the Board of Directors on an annual basis. Projections of macroeconomic variables (GDP, benchmark interest rate and inflation) and of the credit market (fundraising, loans, default rate, spread and fees) for these scenarios are generated based on exogenous shocks or by using models validated by an independent area. These projections affect the budgeted result and balance sheet that then change the risk-weighted assets and capital and liquidity ratios. The stress test is also an integral part of ICAAP, with the main purpose of assessing whether, even in severe adverse conditions, the institution would have appropriate capital levels, not impacting the development of its activities. This information allows to identify potential factors of risks on businesses, supporting the Board of Directors’ strategic decisions, the budgetary process and discussions on credit granting policies, in addition to being used as input for risk appetite metrics. Further details on Risk and Capital Management of ITAÚ UNIBANCO HOLDING and indicators of the Global Systemic Importance Index, which are not included in the financial statements, may be viewed on www.itau.com.br/investor-relations, section “Reports”/ Pillar 3 and Global Systemically Important Banks. VI – Leverage Ratio The Leverage Ratio is defined as the rate between Capital Tier I and Total Exposure, calculated pursuant to BACEN Circular 3,748, of February 27, 2015. The purpose of this ratio is to be a simple measure of leverage not sensitive to risk, thus it does not consider weighting or mitigation factors. According to instructions provided by BACEN Circular Letter 3,706, of May 5, 2015, since October 2015, ITAÚ UNIBANCO HOLDING has sent the Leverage Ratio to BACEN, in accordance with Basel recommendations, and the basis was established as the ratio behavior observation period since its implementation in 2011 until 2017. More information on the composition of the Leverage Ratio, which are not part of its financial statements, is available at www.itau.com.br/investors-relations, “Reports” / Pillar 3 and Global Systemically Important Banks. d) Management Risks of insurance and private pension I – Management Structure, roles and responsibilities In line with good national and international practices, ITAÚ UNIBANCO HOLDING has a risk management structure that ensures that the risks arising from insurance, pension plan and capitalization products are properly reported to the proper bodies. The management process of insurance, pension plan and capitalization risks is independent and focused on the specifics of each risk. ITAÚ UNIBANCO HOLDING has specific committees to define the management of funds from the technical reserves for insurance and private pension, issue guidelines for managing these funds with the objective of achieving long term return, and define evaluation models, risk limits and strategies on allocation of funds to defined financial assets. Such committees are comprised not only of executives and those directly responsible for the business management process, but also for an equal number of professionals that head up or coordinate the commercial and financial areas. Itaú Unibanco Holding S.A. – Complete Financial Statements in IFRS – March 31, 2019 139 V - Stress testing The stress test is a process of simulation of extreme economic and market conditions in the institution’s results and capital. The institution has conducted this test since 2010 aiming at assessing its solvency in plausible scenarios of a systemic crisis, as well as at identifying areas that are more susceptible to the impact of stress, and that can be subject to risk mitigation. To perform the test, macroeconomic variables for each stress scenario are estimated by the economic research department. The scenarios are established considering their relevance to the bank’s result, and the probability of occurrence, and they are submitted to the approval of the Board of Directors on an annual basis. Projections of macroeconomic variables (GDP, benchmark interest rate and inflation) and of the credit market (fundraising, loans, default rate, spread and fees) for these scenarios are generated based on exogenous shocks or by using models validated by an independent area. These projections affect the budgeted result and balance sheet that then change the risk-weighted assets and capital and liquidity ratios. The stress test is also an integral part of ICAAP, with the main purpose of assessing whether, even in severe adverse conditions, the institution would have appropriate capital levels, not impacting the development of its activities. This information allows to identify potential factors of risks on businesses, supporting the Board of Directors’ strategic decisions, the budgetary process and discussions on credit granting policies, in addition to being used as input for risk appetite metrics.

II – Risks of Insurance and Private Pension ITAÚ UNIBANCO HOLDING offers its products to clients through bancassurance or direct distribution. Life, accident, credit life and multiple peril insurance products are mainly distributed by bancassurance operation. Life insurance and pension plans are, in general, medium or long-lived products and the main risks involved in the business may be classified as biometric risk, financial and behaviorall. · Biometric risk relates to: i) more than expected increase in life expectancies for products with survivorship coverage (mostly pension plans); and ii) more than expected decrease in mortality rates for products with survivorship coverage (mostly life insurance). · Financial risk: is inherent in the underwriting risk of products that offer a financial guarantee pre- established in an agreement, and this risk is considered insurance risk · Behavioral risk relates to a more than expected increase in the rates of conversion into annuity income, resulting in increased payments of retirement benefits. The estimated actuarial assumptions are based on the historical evaluation of ITAÚ UNIBANCO HOLDING, on benchmarks and the experience of the actuaries.

a) Effect of changes on actuarial assumptions To measure the effects of changes in the key actuarial assumptions, sensitivity tests were conducted in the amounts of current estimates of future liability cash flows. The sensitivity analysis considers a vision of the impacts caused by changes in assumptions, which could affect the income for the period and stockholders’ equity at the balance sheet date. This type of analysis is usually conducted under the ceteris paribus condition, in which the sensitivity of a system is measured when one variable of interest is changed and all the others remain unchanged. The results obtained are shown in the table below: (1) Impact in Results and Stockholders’ Equity (2) 12/31/2018 03/31/2019 Sensitivity analysis Private Pension Insurance Private Pension Insurance Mortality Rates 5% increase 15 (1) 15 (1) 5% decrease ( 16) (1) ( 16) (1) Risk-free Interest Rates 0.1% increase 30 8 30 8 0.1% decrease ( 44) (8) ( 44) (8) Conversion in Income Rates 5% increase ( 14) - ( 14) - 5% decrease 14 - 14 - Claims 5% increase - (37) - (37) 5% decrease - 37 - 37 (1) Amounts net of tax effects.

b) Liquidity Risk Liquidity risk is the risk that ITAÚ UNIBANCO HOLDING may have insufficient net funds available to honor its current obligations at a given moment. The liquidity risk is managed, for insurance operation, continuously based on the monitoring of payment flows related to its liabilities vis a vis the inflows generated by its operations and financial assets portfolio. Financial assets are managed in order to optimize the risk-return ratio of investments, considering, on a careful basis, the characteristics of their liabilities. The risk integrated control considers the concentration limits by issuer and credit risk, sensitivities and market risk limits and control over asset liquidity risk. Thus, investments are concentrated in government and private securities with good credit quality in active and liquid markets, keeping a considerable amount invested in short- term assets, available on demand, to cover regular needs and any liquidity contingencies. Additionally, ITAÚ UNIBANCO HOLDING constantly monitors the solvency conditions of its insurance operations.
