They are measured using best estimates through the use of models and criteria which allow their appropriate measurement even if there is uncertainty as to their ultimate timing and amount, and the criteria are detailed in Note 8. 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 Other Liabilities; • Possible: which are disclosed in the Consolidated Financial Statements, but no provision is recorded; • Remote: which require neither a provision nor disclosure.

Deferred tax assets are only recognized when it is probable that future taxable income will be available for offsetting.

f) Derivative financial Instruments ITAÚ UNIBANCO HOLDING PRUDENTIAL 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. ITAÚ UNIBANCO HOLDING PRUDENTIAL 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. The total value of margins pledged in guarantee by ITAÚ UNIBANCO HOLDING PRUDENTIAL was R$ 10,354,460 (R$ 12,514,240 at 06/30/2018) and was basically comprised of government securities.

Note 8 – Contingent assets and liabilities and legal liabilities – tax and social security ITAÚ UNIBANCO HOLDING PRUDENTIAL, as a result of the ordinary course of its business, may be a party to legal lawsuits of labor, civil and tax nature. The contingencies related to these lawsuits are classified as follows: a) Contingent Assets: There are no contingent assets recorded. b) Provisions and contingencies: The criteria to quantify of provisions for contingencies are adequate in relation to the specific characteristics of civil, labor and tax lawsuits portfolios, as well as other risks, taking into consideration the opinion of its legal advisors, the nature of the lawsuits, the similarity with previous lawsuits and the prevailing previous court decisions. A provision is recognized whenever the loss is classified as probable. Legal liabilities arise from lawsuits filed to discuss the legality and unconstitutionality of the legislation in force, being subject to an accounting provision, regardless of the probability of loss. I- Civil lawsuits: In general, provisions for 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 PRUDENTIAL, 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 PRUDENTIAL 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 PRUDENTIAL 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.

l – Partner Plan The employees and management members of ITAÚ UNIBANCO HOLDING invest a percentage of their bonus to acquire shares and share-based instruments. Accordingly, the ownership of these shares should be held by the beneficiaries for a period from three to five years, counted from the initial investment, and are thus subject to market price variation. After complying with the suspensive conditions set forth in the program, beneficiaries will be entitled to receive shares as consideration, in accordance with the numbers of shares provided for in the program regulation. The acquisition prices of shares and share-based Instruments are established every six months and are equivalent to the average of share quotation in the 30 days prior to the determination of the acquisition price, which is performed on the seventh business day prior to the remuneration grant date.

However, not all instruments have liquidity or quoted market prices and, in such cases, it is necessary to adopt present value estimates and other pricing techniques to establish their market value. In the absence of the prices quoted by the Brazilian Financial and Capital Markets Association (ANBIMA), the market values of government securities are determined based on the interest rates provided by brokers. The market values of corporate debt securities are calculated by discounting estimated cash flows at market interest rates. The market values of shares are computed based on their prices quoted in the market. The market values of derivative financial instruments were determined as follows: • Swaps: Their 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 market 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 using 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 market value of the underlying asset. Current market prices of options are used to compute the implicit volatilities. • Credit Risk: 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 and other credits – Market value is estimated based on groups of loans with similar financial and risk characteristics, using valuation models. The market value of fixed-rate loans was determined by discounting estimated cash flows, applying current interest rates close of similar loans. For the majority of loans at floating rate, the carrying amount was considered close to their market value. The market value of loan and lease operations not overdue was calculated by discounting the expected payments of principal and interest through maturity. The market 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 information specific of the debtor.

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. 06/30/2019 06/30/2018 (1) Discount rate 9.72% p.a. 9.98% p.a.

Growth of the pension fund benefits 4.00 % p.a. 4.00 % p.a. Inflation 4.00 % p.a. 4.00 % 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. - Biometric 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.

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. - Biometric 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.

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 carried out under the ceteris paribus condition, in which the sensitivity of a system is measured when only one variable of interest is changed and all the others remain unchanged.

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 CONSOLIDATED. Among BACEN’s requirement for proper risk and capital management, noteworthy are the Risk Appetite Statement” (RAS) and the implementation of continuous and integrated risk management structure, the stress test program, the organization of the Risk Committee and nomination, before BACEN, of the Chief Risk Officer (CRO), with assignment of roles, responsibilities and independence requirements.

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. This structure has specific limits aiming at improving the risk monitoring and understanding process, and at avoiding concentration. These limits are quantified by assessing the forecasted results of the balance sheet, size of stockholders’ equity, liquidity, market complexity and volatility, as well as the institution’s appetite for risk. In order to set up operations within the defined limits, ITAÚ UNIBANCO HOLDING CONSOLIDATED hedges transactions with clients and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, and can be characterized as accounting or economic hedge, both governed by the institutional polices of ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 5 - Securities and derivative financial instruments). The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution nº. 4,557, of February 2017, 23, and BACEN Circular nº. 3,354, of June 2007, 27. The trading portfolio consists of all transactions involving financial instruments and goods, including derivatives, which are carried out with the intention of trading. The banking portfolio is basically characterized by transactions from the banking business, and transactions related to the management of the balance sheet of the institution, it has the no-intention of resale and medium and long term time horizons as general guidelines. Market risk management analyses is conducted based on the following metrics: • Value at risk (VaR): statistical measure that estimates the expected maximum potential economic loss under normal market conditions, considering a certain time horizon and confidence level; • Losses in stress scenarios: simulation technique to assess the behavior of assets, liabilities and derivatives of a portfolio when several risk factors are taken to extreme market situations (based on prospective and historical scenarios); • Stop loss: metrics which purpose is to review positions, should losses accumulated in a certain period reach a certain amount; • Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at market value (“MtM – Mark to Market”); and • Stressed VaR: statistical metric arising from VaR calculation, which purpose is to capture higher risk in simulations for the trading portfolio, considering returns that can be seen in historical scenarios of extreme volatility. 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 CONSOLIDATED uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in an access-controlled environment, being highly available, which has data safekeeping and recovery processes and counts on such an infrastructure to ensure the continuity of business in contingency (disaster recovery) situations.

IV – Operational risk The possibility of losses from failure of, insufficient or inadequate internal processes, people and systems, or from external events impacting the realization of strategic, tactical or operational objectives. It includes the legal risk, associated with the inadequacy or deficiency in agreements signed by the institution, as well as sanctions for failing to meet legal provisions and compensation for damages to third parties arising from activities performed by the institution. The managers of executive areas adopt corporate methodologies developed and made available by the internal controls, compliance and operational risk area. As part of governance of risk management process, consolidated reports on risk monitoring, controls, action plans and operating losses are periodically presented to the business areas’ executives. In line with the principles of CMN Resolution No. 4,557, of February 2017, 23, the document entitled “Public Access Report – Integrated Management of Operational Risk and Internal Controls“, a summarized version of the institutional operational risk management policy, may be accessed on the website www.itau.com.br/investor- relations, section Itaú Unibanco, “Corporate Governance”, Rules and Policies, Reports. V - Social and environmental risk Risk of potential losses due to exposure to social and environmental damages arising from the performance of its activities. The social and environmental risk management is carried out by the first line of defense in its daily operations, with the technical assessment of the legal and risk areas, which have a technical dedicated team. Business units also have governance for approval of new products, which includes the assessment of the social and environmental risk, therefore ensuring compliance with this requirement for all new products approved by the institution. Governance still has the Social and Environmental Risk Committee, which main duty is to guide the institutional understanding related to exposure to social and environmental risk for the institution’s activities. Mitigation actions concerning the social and environmental risk are carried out by mapping processes, risks and controls, monitoring new regulations on the subject, and recording any occurrences in internal databases. In addition to identification, the phases of prioritization, response, monitoring and reporting of assessed risks supplement this risk monitoring at ITAÚ UNIBANCO HOLDING CONSOLIDATED.

It includes the legal risk, associated with the inadequacy or deficiency in agreements signed by the institution, as well as sanctions for failing to meet legal provisions and compensation for damages to third parties arising from activities performed by the institution. The managers of executive areas adopt corporate methodologies developed and made available by the internal controls, compliance and operational risk area. As part of governance of risk management process, consolidated reports on risk monitoring, controls, action plans and operating losses are periodically presented to the business areas’ executives. In line with the principles of CMN Resolution No. 4,557, of February 2017, 23, the document entitled “Public Access Report – Integrated Management of Operational Risk and Internal Controls“, a summarized version of the institutional operational risk management policy, may be accessed on the website www.itau.com.br/investor- relations, section Itaú Unibanco, “Corporate Governance”, Rules and Policies, Reports. V - Social and environmental risk Risk of potential losses due to exposure to social and environmental damages arising from the performance of its activities. The social and environmental risk management is carried out by the first line of defense in its daily operations, with the technical assessment of the legal and risk areas, which have a technical dedicated team. Business units also have governance for approval of new products, which includes the assessment of the social and environmental risk, therefore ensuring compliance with this requirement for all new products approved by the institution. Governance still has the Social and Environmental Risk Committee, which main duty is to guide the institutional understanding related to exposure to social and environmental risk for the institution’s activities. Mitigation actions concerning the social and environmental risk are carried out by mapping processes, risks and controls, monitoring new regulations on the subject, and recording any occurrences in internal databases. In addition to identification, the phases of prioritization, response, monitoring and reporting of assessed risks supplement this risk monitoring at ITAÚ UNIBANCO HOLDING CONSOLIDATED.

In preparing the consolidated financial statements, management is responsible for assessing the Bank's ability to continue as going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Bank or to cease operations, or has no realistic alternative but to do so. Those charged with governance in the Bank and its subsidiaries are responsible for overseeing the financial reporting process of the Prudential Conglomerate. Auditor's responsibilities for the audit of the consolidated financial statements Our objectives are to obtain reasonable assurance about whether the consolidated financial statements of the Prudential Conglomerate, prepared in accordance with Resolution 4,280 of CMN, and supplementary regulations of BACEN, as a whole, are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that the audit conducted in accordance with the Brazilian and International Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements. As part of an audit in accordance with Brazilian and International Standards on Auditing, taking into consideration the NBC TA 800 (Special Conditions – Audit Financial Statements in accordance with special purpose accounting conceptual structures), we exercise professional judgment and maintain professional skepticism throughout the audit. We also: • Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. • Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal control of the Bank and its subsidiaries. • Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management. • Conclude on the appropriateness of management's use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Bank's ability to continue as going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the Bank to cease to continue as going concern. 4 In preparing the consolidated financial statements, management is responsible for assessing the Bank's ability to continue as going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Bank or to cease operations, or has no realistic alternative but to do so.
