Note 4 – Summary of the main accounting practices a) Cash and cash equivalents - For the purpose of the Consolidated Statement of Cash Flows, this item includes cash and current accounts in banks (considered in the heading cash and cash equivalents), interbank deposits and securities purchased under agreements to resell – funded positions that have original maturities of up to 90 days. b) Interbank investments, Remunerated restricted credits – Brazilian Central Bank, Remunerated deposits, Deposits received under securities repurchase agreements, funds from acceptance and issuance of securities, Borrowing and onlending, Subordinated debt and Other receivables and payables – Operations with fixed remuneration and charges are accounted for at present value. Operations with post-fixed or floating remuneration and charges are accounted for at the adjusted principal amount. Operations subject to foreign exchange variation are accounted for at the corresponding amount in local currency. Liabilities are presented net of the transaction costs incurred, when relevant, calculated pro rate die. c) Securities - Recorded at the cost of acquisition restated by the index and/or effective interest rate and presented in the Balance Sheet, according to BACEN Circular No. 3,068, of November 8, 2001. Securities are classified into the following categories: · Trading securities – securities acquired to be actively and frequently traded, and adjusted to market value, with a counter-entry to the results for the period; · Available-for-sale securities – securities that can be negotiated but are not acquired to be actively and frequently traded, adjusted to their market value with a counter-entry to an account disclosed in stockholders’ equity; · Held-to-maturity securities – securities, except for non-redeemable shares, for which the bank has the financial condition and intends or is required to hold them in the portfolio up to their maturity, are recorded at cost of acquisition, or market value, whenever these are transferred from another category. The securities are adjusted using the accrual method through their maturity date, not being adjusted to market value. Gains and losses on available-for-sale securities, when realized, are recognized at the trade date in the statement of income, with a counter-entry to a specific stockholders’ equity account. Decreases in the market value of available-for-sale and held-to-maturity securities below their related costs, resulting from non-temporary reasons, are recorded in results as realized losses. d) Derivative financial instruments - these are classified on the date of their acquisition, according to management's intention of using them either as a hedge or not, according to BACEN Circular No. 3,082, of January 30, 2002. Transactions involving financial instruments, carried out upon the client’s request, for their own account, or which do not comply with the hedging criteria (mainly derivatives used to manage the overall risk exposure), are stated at market value, including realized and unrealized gains and losses, which are recorded directly in the Statement of Income. The derivatives that are used for protection against risk exposure or to modify the characteristics of financial assets and liabilities, which have changes in market value highly associated with those of the items being protected at the beginning and throughout the duration of the contract, and which are found effective to reduce the risk related to the exposure being protected, are classified as a hedge, in accordance with their nature: · Market Risk Hedge – financial assets and liabilities, as well as their related financial instruments, are accounted for at their market value plus realized and unrealized gains and losses, which are recorded directly in the Statement of Income. · Cash Flow Hedge - the effective amount of the hedge of financial assets and liabilities, as well as their related financial instruments, are accounted for at their market value plus realized and unrealized gains and losses, net of tax effects, when applicable, and recorded in a specific account in stockholders’ equity. The ineffective portion of the hedge is recorded directly in the Statement of Income.

Transactions involving financial instruments, carried out upon the client’s request, for their own account, or which do not comply with the hedging criteria (mainly derivatives used to manage the overall risk exposure), are stated at market value, including realized and unrealized gains and losses, which are recorded directly in the Statement of Income. The derivatives that are used for protection against risk exposure or to modify the characteristics of financial assets and liabilities, which have changes in market value highly associated with those of the items being protected at the beginning and throughout the duration of the contract, and which are found effective to reduce the risk related to the exposure being protected, are classified as a hedge, in accordance with their nature: · Market Risk Hedge – financial assets and liabilities, as well as their related financial instruments, are accounted for at their market value plus realized and unrealized gains and losses, which are recorded directly in the Statement of Income. · Cash Flow Hedge - the effective amount of the hedge of financial assets and liabilities, as well as their related financial instruments, are accounted for at their market value plus realized and unrealized gains and losses, net of tax effects, when applicable, and recorded in a specific account in stockholders’ equity.

f) Derivative financial Instruments The globalization of the markets in recent years has resulted in a high level of sophistication of financial products used. As a result of this process, there has been increasing demand for derivative financial instruments to manage market risks, mainly arising from fluctuations in interest and exchange rates, commodities and other asset prices. Accordingly, ITAÚ UNIBANCO HOLDING PRUDENTIAL and its subsidiaries operate in the derivatives markets for meeting the growing needs of their clients, as well as enacting their risk management policy. This policy is based on the use of derivative instruments to minimize the risks resulting from commercial and financial operations. The derivative financial instrument business with clients is carried out after the approval of credit limits. The process of limit approval takes into consideration potential stress scenarios. Knowing the client, the sector in which it operates and its risk appetite profile, in addition to providing information on the risks involved in the transaction and the negotiated conditions, ensures transparency in the relationship between the parties and the supply of a product that better meets the needs of the client. The derivative transactions carried out by ITAÚ UNIBANCO HOLDING PRUDENTIAL and its subsidiaries with clients are neutralized in order to eliminate market risks. The derivative contracts traded by the institution with clients in Brazil include swaps, forwards, options and futures contracts, which are registered at the B3 or at the CETIP S.A. OTC Clearing House (CETIP). Overseas transactions are carried out with futures, forwards (onshore), options and swaps mostly listed on the Chicago, New York and London Exchanges. It should be emphasized that there are over-the-counter operations, but their risks are low compared to the institutions’ total. Noteworthy is also the fact that there are no structured operations based on subprime assets and all operations are based on risk factors traded on stock exchanges. The main risk factors of the derivatives, assumed at 06/30/2018, were related to the foreign exchange rate, interest rate, commodities, US Dollar coupon, Reference Rate coupon, LIBOR and variable income. The management of these and other market risk factors is supported by sophisticated statistical and deterministic models. Based on this management model, the institution, through the use of transactions involving derivatives, has been able to optimize the risk-return ratios, even in highly volatile situations. Most derivatives included in the institution’s portfolio are traded on stock exchanges. The prices disclosed by stock exchanges are used for these derivatives, except in cases in which the low representativeness of price due to the liquidity of a specific contract is identified. Derivatives typically valued in this way are futures contracts. Likewise, there are other instruments whose quotations (fair prices) are directly disclosed by independent institutions and which are valued based on this direct information. A substantial portion of the Brazilian government securities, highly-liquid international (public and private) securities and shares are in this situation. For derivatives the prices of which are not directly disclosed by stock exchanges, fair prices are obtained based on pricing models which use market information, deducted based on the prices disclosed for higher liquidity assets. Interest and market volatility curves which provide input for the models are extracted from those prices. Over- the-counter derivatives, forward contracts and securities with limited liquidity are in this situation. The total value of margins pledged in guarantee was R$ 12,514,240 (R$ 7,089,954 at 06/30/2017) and was basically composed of government securities. f) Derivative financial Instruments The globalization of the markets in recent years has resulted in a high level of sophistication of financial products used.

g) Sensitivity analysis (trading and banking portfolios) In compliance with CVM Instruction No. 475, ITAÚ UNIBANCO HOLDING PRUDENTIAL carried out a sensitivity analysis by market risk factors considered relevant to which it was exposed. The biggest losses arising, by risk factor, in each scenario, were stated with impact on result, net of tax effects, by providing a vision of the ITAÚ UNIBANCO HOLDING PRUDENTIAL exposure under exceptional scenarios. The sensitivity analyses of the non-trading and the trading portfolio shown in this report are an evaluation of a static position of the portfolio exposure and, therefore, do not consider the management’s quick response capacity (treasury and control areas), which triggers risk mitigating measures, whenever a situation of high loss or risk is identified by minimizing the sensitivity towards significant losses. In addition, we point out that the presented results do not necessarily translate into accounting results, because the study's sole purpose is to disclose the exposure to risks and the respective protective actions, taking into account the fair value of financial instruments, irrespective of the accounting practices adopted by the ITAÚ UNIBANCO HOLDING PRUDENTIAL.

Note 11 – 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 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. - Civil lawsuits: In general, 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. Contingencies 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. Probability of loss, which is estimated based on the characteristics of the lawsuit. The amounts considered as probable losses are recorded as provisions. It should be mentioned that ITAÚ UNIBANCO HOLDING PRUDENTIAL is a party to specific lawsuits related to the collection of understated inflation adjustments to savings accounts resulting from economic plans implemented in the 80’s and 90’s as a measure to combat inflation.

g) Share-based payment ITAÚ UNIBANCO HOLDING and its subsidiaries have share-based payment programs aimed at involving its management members and employees in the medium and long term corporate development process. These payments are only made in years where there are sufficient profits to enable the distribution of mandatory dividends, in order to limit the maximum dilutive effect to which stockholders are subject, and at a quantity that does not exceed the limit of 0.5% of the total shares held by the controlling and minority stockholders at the balance sheet date. These programs are settled through the delivery of ITUB4 treasury shares to stockholders. From 01/01 to 06/30/2018, the accounting effect of the Share-based payment in income was R$ (313,883) (R$ (253,910) from 01/01 to 06/30/2017). I – Stock Option Plan (Simple Options) ITAÚ UNIBANCO HOLDING has a Stock Option Plan (“Simple Options”) aimed at involving management members and employees in the medium and long term corporate development program of ITAÚ UNIBANCO HOLDING and its subsidiaries, offering them the opportunity to benefit from the appreciation that their work and dedication bring to the shares. In addition to the awards provided under the Plan, ITAÚ UNIBANCO HOLDING also maintains control over the rights and obligations in connection with the options granted under the plans approved at the Extraordinary Stockholders’ Meetings held on April 24, 2009 and April 19, 2013 related to the Unibanco – União de Bancos Brasileiros S.A., Unibanco Holdings S.A. and Redecard S.A. stock option plans, respectively. Accordingly, the exchange of shares for ITUB4 did not have a relevant financial impact. Simple options have the following characteristics: a) Exercise price: calculated based on the average prices of shares in the three months of the year prior to the grant date. The prices determined will be inflation-adjusted to the last business day of the month prior to the option exercise date based on IGP-M or, in its absence, on an index to be determined internally, and should be paid within the period in force for the settlement of operations on B3. b) Vesting period: determined upon issue, from one to seven years, counted from the grant date. The vesting period is normally determined at five years. c) Fair value and economic assumptions for cost recognition: the fair value of Simple Options is calculated on the grant date based on the Binominal model. Economic assumptions used are as follows: (i) Exercise price: exercise price previously agreed upon the option issue, adjusted by the IGP-M variation; (ii) Price of the underlying asset (ITUB4 shares): closing price on B3 on the calculation base date; (iii) Expected dividends: the average annual return rate for the last three years of dividends paid plus interest on capital of the ITUB4 share; (iv) Risk-free interest rate: IGP-M coupon rate at the expiration date of the Simple Option; (v) Expected volatility: calculated based on the standard deviation from the history of the last 84 monthly returns of the ITUB4 share closing prices, disclosed by B3, adjusted by the IGP-M variation. g) Share-based payment ITAÚ UNIBANCO HOLDING and its subsidiaries have share-based payment programs aimed at involving its management members and employees in the medium and long term corporate development process. These payments are only made in years where there are sufficient profits to enable the distribution of mandatory dividends, in order to limit the maximum dilutive effect to which stockholders are subject, and at a quantity that does not exceed the limit of 0.5% of the total shares held by the controlling and minority stockholders at the balance sheet date.

ll – Partner Plan The employees and management members of ITAÚ UNIBANCO HOLDING and its subsidiaries may be selected to participate in the program investing a percentage of their bonus to acquire ITUB4 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 ITUB4 as consideration, in accordance with the numbers of shares provided for in the program regulation. The acquisition prices of own shares and Share-Based Instruments are established every six months and are equivalent to the average of the ITUB4 quotation in the 30 days prior to the determination of the acquisition price. The fair value of the ITUB4 as consideration is the market price at the grant date, less expected dividends. The weighted average of the fair value of the ITUB4 shares as consideration was estimated at R$ 39.33 per share at 06/30/2018 (R$ 32.33 per share at 06/30/2017). Law nº. 12,973/14, which adjusted the tax legislation to the international accounting standards and terminated the Transitional Tax Regime (RTT), set up a new legal framework for payments made in shares.

III- Variable Compensation The policy established in compliance with CMN Resolution nº. 3,921/10 sets forth that fifty percent (50%) of the management’s variable compensation should be paid in cash and fifty percent (50%) should be paid in shares for a period of three years. Shares are delivered on a deferred basis, of which one-third (1/3) per year, will be contingent upon the executive’s remaining with the institution. The deferred unpaid portions may be reversed proportionally to the significant reduction of the recurring income realized or the negative income for the period.

To obtain the market values for these financial instruments, the following criteria were adopted: · Interbank investments were determined based on their nominal amounts, monetarily restated as at their maturity dates and discounted to present value using future market interest rates and swap market rates for fixed-rate securities and using market interest rates for fixed-rate securities, achieved up to the closing of B3 at the balance sheet date, for floating-rate securities; · Securities and derivative financial instruments, according to the rules established by Circulars No. 3,068 and 3,082 of November 8, 2001 and January 30, 2002, respectively, issued by BACEN, are recorded at their market values, except for those classified as Held to Maturity. Government securities allocated in this category have their market value calculated based on the rates obtained in the market, and validated through the comparison with information provided by the National Association of Financial Market Institutions (ANBIMA). Private securities included in this category have their market value calculated using a criterion similar to the one adopted for Investments in Interbank Deposits, as described above; · Loans with maturities over 90 days, when available, were calculated based on the net present value of future cash flows discounted at market interest rates effective on the balance sheet date; · Investments - in company B3 at the share value quoted on stock exchanges. · Time and interbank deposits and funds from the acceptance and issuance of securities and foreign borrowing through securities, when available, were calculated based on their present value determined by future cash flows discounted at market rates obtained at the closing of B3 on the balance sheet date; · Subordinated debt, based on the net present value of future fixed or floating cash flows in foreign currency, net of the market interest rates effective on the balance sheet date and considering the credit risk of the issuer. The floating cash flows are estimated from the interest curves of the indexation market places; · Treasury shares are valued according to the average quotation available on the last trading day of the month or, if this is not available, according to the most recent quotation on prior trading days, published in the daily bulletin of each Stock Exchange.

a) Retirement plans ITAÚ UNIBANCO HOLDING PRUDENTIAL and certain subsidiaries sponsor defined benefit and variable contribution plans, whose basic purpose is to grant benefits that, in general, provide a life annuity benefit, and may be converted into survivorship annuities, according to the plan's regulations. They also sponsor defined contribution plans, the benefit of which is calculated based on the accumulated balance at the eligibility date, according to the plan's regulations, which does not require actuarial calculation, except as described in Note 18c. Employees hired prior to July 31, 2002, for those who came from Itaú, and prior to February 27, 2009 for those who came from Unibanco, are beneficiaries of the above-mentioned plans. As regards the employees hired after these dates, they have the option to voluntarily participate in a variable contribution plan (PGBL), managed by Itaú Vida e Previdência S.A. Supplementary plans are managed by closed-end private pension entities (EFPC) with independent legal structures, as detailed below: Entity Benefit plan (1) Fundação Itaú Unibanco - Previdência Complementar Supplementary retirement plan – PAC (1) Franprev benefit plan - PBF (1) 002 benefit plan - PB002 (1) Itaulam basic plan - PBI (2) Itaulam Supplementary Plan - PSI (3) Itaubanco Defined Contribution Plan (3) Itaubank Retirement Plan (1) Itaú Defined Benefit Plan (2) Itaú Defined Contribution Plan (3) Unibanco Pension Plan (1) Prebeg benefit plan (1) UBB PREV defined benefit plan (1) Benefit Plan II (1) Supplementary Retirement Plan – Flexible Premium Annuity (ACMV) (1) REDECARD Basic Retirement Plan (2) REDECARD Supplementary Retirement Plan (3) REDECARD Pension Plan (1) ITAUCARD Retirement Defined Benefit Plan (2) ITAUCARD Supplementary Retirement Plan (1) Funbep Fundo de Pensão Multipatrocinado Funbep I Benefit Plan (2) Funbep II Benefit Plan (1) Defined benefit plan; (2) Variable contribution plan; (3) Defined contribution plan. b) Governance The closed-end private pension entities (EFPC) and benefit plans they manage are regulated in conformity with the related specific legislation.

c) Defined benefit plan I - Main assumptions used in actuarial valuation of Retirement Plans 06/30/2018 06/30/2017 (1) Discount rate 9.98% p.a. 10.24% p.a. (2) Mortality table AT-2000 AT-2000 Itaú Experience Itaú Experience (3) Turnover 2008/2010 2008/2010 Future salary growth 5.04% to 7.12 % p.a. 5.04% to 7.12 % p.a. Growth of the pension fund and social security benefits 4.00 % p.a. 4.00 % p.a. Inflation 4.00 % p.a. 4.00 % p.a. (4) Actuarial method Projected Unit Credit Projected Unit Credit (1) The adoption of this assumption is based on interest rates obtained from the actual interest curve in IPCA, for medium term liabilities of retirement plans sponsored by ITAÚ UNIBANCO HOLDING PRUDENTIAL. At 12/31/2017 assumption were adopted consistently with the economic scenario at the balance sheet date rate, considering the volatility of the interest markets and the models adopted; (2) The mortality tables adopted correspond to those disclosed by Society of Actuaries (SOA), the North-American Entity which corresponds to Brazilian Institute of Actuarial Science (IBA), which reflects a 10% increase in the probabilities of survival compared to the respective basic tables. The life expectancy in years per the AT-2000 mortality table for participants aged 55 years is 27 and 31 years for men and women, respectively; (3) The turnover assumption is based on the effective experience of ITAÚ UNIBANCO HOLDING PRUDENTIAL, resulting in the average of 2.4% p.a. based on the 2008/2010 experience; (4) Using the Projected Unit Credit, the mathematical reserve is determined based on the current projected benefit amount multiplied by the ratio between the length of service in the company at the assessment date and the length of service that will be reached at the date when the benefit is granted. The cost is determined taking into account the current projected benefit amount distributed over the years that each participant is employed. In case of benefits sponsored by foreign subsidiaries, actuarial assumptions adequate to the group of participants and the country's economic scenario are adopted. Biometric/demographic assumptions adopted are consistent with the group of participants of each benefit plan, pursuant to the studies carried out by an independent external actuarial consulting company. The main differences between the assumptions above and those adopted upon determination of the actuarial liability of defined benefit plans, for the purposes of recording in the balance sheet of the closed-end private pension entities (EFPCs) that manage them, are the discount rate and the actuarial method. Regarding the discount rate assumption, EFPCs adopt a rate consistent with the flow of receipts/payments, in accordance with the study conducted by an independent external consulting company. Regarding the actuarial method, the aggregate method is adopted, by which the mathematical reserve is defined based on the difference between the present value of the projected benefit and the present value of future contributions, subject to the methodology defined in the respective actuarial technical note. II - Risk Exposure Due to its defined benefit plans, ITAÚ UNIBANCO HOLDING PRUDENTIAL is exposed to a number of risks, the most significant ones are: - Volatility of assets The actuarial liability is calculated by adopting a discount rate defined based on the income related to securities issued by the Brazilian treasury (government securities). If the actual income related to plan investments is lower than expected, this may give rise to a deficit. The plans have a significant percentage of fixed-income securities pegged to the plan commitments, aimed at minimizing volatility and short and medium term risk. - Changes in investment income A decrease in income related to public securities will imply a decrease in the discount rate and, therefore, will increase the plan’s actuarial liability. The effect will be partially offset by the recognition of these securities at market value. - Inflation risk Most of the plan benefits are pegged to the inflation rates, and a higher inflation will lead to higher obligations. The effect will also be partially offset because a significant portion of the plan assets is pegged to government securities restated at the inflation rate. c) Defined benefit plan I - Main assumptions used in actuarial valuation of Retirement Plans 06/30/2018 06/30/2017 (1) Discount rate 9.98% p.a. 10.24% p.a.

- Life expectancy Most of the plan obligations are to provide life benefits, and therefore an increase in life expectancy will result in increased plan liabilities. III – Management of defined benefit plan assets The general purpose of managing EFPC funds is to search for a long term balance between assets and obligations to pay of retirement benefits, by exceeding the actuarial targets (discount rate plus benefit adjustment index, established in the plan regulations). Regarding the assets guaranteeing the actuarial liability reserves, management should ensure the payment capacity of retirement benefits in the long term by avoiding the risk of mismatching assets and liabilities in each pension plan. - Life expectancy Most of the plan obligations are to provide life benefits, and therefore an increase in life expectancy will result in increased plan liabilities.

Note 20 – Risk and capital management On February 23, 2017, BACEN published CMN Resolution 4,557, which was in force on August 21, 2017, and revokes CMN Resolutions 3,380, 3,464, 3,721, 3,988, and 4,090, which provide for the implementation of management structure of operating, market, credit, capital and liquidity risk, respectively. Assuming and managing risks is one of the activities carried out by Itaú Unibanco and, accordingly, the institution should have established objectives for risk management. Accordingly, the risk appetite defines the nature and level of risks acceptable for the institution and the risk culture guides the attitudes required to manage them. Itaú Unibanco seeks robust process for risk management, which permeate the whole institution and that are the basis for strategic decisions to assure the sustainability of business. These processes are aligned with the guidelines of the Board of Directors and Executives that, through corporate bodies, define the global objectives that are measured as goals and limits to the risk management units. Control and capital management units, in turn, support the Itaú Unibanco’s management by monitoring and analyzing risk and capital. The principles providing the foundations for management of risk, risk appetite and guidelines on how Itaú Unibanco’s employees should behave on the day-to-day for decision-making purposes are as follows: · Sustainability and Client Satisfaction: Itaú Unibanco’s vision is to be the leading bank in sustainable performance and client satisfaction and, therefore, it is committed to creating shared value to employees, clients, stockholders, and society, ensuring the continuity of business. Itaú Unibanco is committed to do business that is good both for the client and the institution itself. · Risk Culture: The institution’s risk culture goes beyond policies, procedures or processes, as it strengthens the individual and collective responsibility of all employees so they do the right thing at the right moment and on the proper way, by respecting the ethical way of doing business. The Risk Culture is described below. · Risk Pricing: Itaú Unibanco acts and assumes risks in business it knows and understands, avoiding risks that are unknown to the institution or that do not have a competitive edge, therefore carefully assessing the risk-return ratio. · Diversification: the institution’s appetite is low with respect to volatility in results and, therefore, it operates with a diversified base of clients, products and business, seeking to diversify risks and giving priority to lower risk business. · Operational Excellence: It is the wish of Itaú Unibanco to be an agile bank, with a robust and stable infrastructure to offer top services. · Ethics and Respect for Regulation: for Itaú Unibanco, ethics is non-negotiable; therefore, the institute promotes an institutional environment that has integrity, guiding employees to cultivate ethics in relationships and business, and the respect for rules, as it cultivates the care for the institution’s reputation. On August 21, 2017, CMN Resolution 4,557, which provides for the capital and risk management structure, came into force. In the resolution, noteworthy are the implementation of continuous and integrated risk management structure, requirements for definition of the “Risk Appetite Statement” (RAS) and 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. Itaú Unibanco complies with the best risk and capital management practices set forth in CMN Resolution 4,557, so that there are no negative impacts resulting from its adoption. Aiming to strengthen these values and align ITAÚ UNIBANCO HOLDING CONSOLIDATED’s employees’ behavior with its risk management guidelines, the institution adopts a number of initiatives to disseminate the risk culture. ITAÚ UNIBANCO HOLDING CONSOLIDATED’s risk culture is based on four basic principles: conscious risk-taking, discussion of the risks the institution faces, the corresponding action taken, and the responsibility of everyone to manage risks. These principles lay down the basis for ITAÚ UNIBANCO HOLDING CONSOLIDATED’s guidelines by helping employees to consciously understand, identify, measure, manage and mitigate risks. In addition to policies, procedures and processes, the risk culture strengthens the individual and collective responsibility of employees in the management of risks inherent in the activities performed individually, respecting the ethical way of managing business.

Aiming to strengthen these values and align ITAÚ UNIBANCO HOLDING CONSOLIDATED’s employees’ behavior with its risk management guidelines, the institution adopts a number of initiatives to disseminate the risk culture. ITAÚ UNIBANCO HOLDING CONSOLIDATED’s risk culture is based on four basic principles: conscious risk-taking, discussion of the risks the institution faces, the corresponding action taken, and the responsibility of everyone to manage risks. These principles lay down the basis for ITAÚ UNIBANCO HOLDING CONSOLIDATED’s guidelines by helping employees to consciously understand, identify, measure, manage and mitigate risks. In addition to policies, procedures and processes, the risk culture strengthens the individual and collective responsibility of employees in the management of risks inherent in the activities performed individually, respecting the ethical way of managing business.

ITAÚ UNIBANCO HOLDING CONSOLIDATED promotes the risk culture, emphasizing the behavior that will help people in any level of the institution to assume and manage risk on a responsible way. With these principles disseminated by the institution, there is an incentive for the risk to be understood and discussed frankly, maintained within the limits established for risk appetite, and so that each employee, regardless of their position, area or function, also assumes responsibility for managing risks of their business. ITAÚ UNIBANCO HOLDING CONSOLIDATED also provides channels for reporting operational failures, internal or external frauds, and conflicts in the work environment or situations that might cause disruptions and/or losses to the institution or adversely affect clients. Every employee and third party is responsible for reporting any issues on a promptly basis, as soon as they become aware of the fact. The Board of Directors is the primary body in the establishment of guidelines, policies, and approval level 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 roles related to capital and risk management. In the executive level, panels, presided over by the Chief Executive Officer (CEO) of Itaú Unibanco, are responsible for capital and risk management and which decisions are monitored in the scope of CGRC. Additionally, the institution has panels, which exercise the responsibilities delegated in capital and risk management, presided over by the Executive Vice-President of the Risk and Finance Department (ARF). Additionally, to support this structure, ARF is structured by specialized officers. The purpose is to ensure, on an independent and centralized basis, that risks and capital of the institution are management in compliance with established the policies and procedures. A detailed description of this structure may be found in the Consolidated Annual Report, in the section our Risk Management. The Consolidated Annual Report is available on the website www.itau.com.br/investors-relations in the section Financial Information. The risk management organizational structure of Itaú Unibanco is in compliance with the regulations in force in Brazil and abroad, and in line with the best practices of the market. The responsibilities for risk management at Itaú Unibanco are structured in accordance with three defense lines, to wit: · in the first defense line, business areas and back-office corporate areas manage risks originated by them, through their identification, assessment, control and report thereof; · in the second defense line, an independent unit controls risks on a centralized basis, aiming at assuring that the risks of Itaú Unibanco are managed in accordance with the appetite for risk, and the policies and procedures established. Thus, the centralized control provides the Board of Directors and the executives with a global vision of exposures of Itaú Unibanco so as to optimize and expedite corporate decisions; · in the third defense line, internal audit performs the independent assessment of the activities carried out in the institution, enabling top management to measure the adequacy of controls, effectiveness of risk management and compliance with internal rules and regulatory requirements. Itaú Unibanco uses automated and robust systems to fully meet capital regulations and to measure risks following regulatory requirements and models in effect. It also coordinates actions to check for adherence to qualitative and quantitative requirements established by the regulatory bodies for compliance with the minimum mandatory capital requirement and risk monitoring.

I – Market risk Market risk is the possibility of incurring financial losses arising from the changes in the market value of positions held by a financial institution, including the risks of transactions subject to foreign exchange variation, interest rates, share prices, price indexes and commodity prices. Market Risk Management Policy is in line with the principles of Resolution nº. 3,464, issued by the National Monetary Council (CMN) and posterior amendments, being a set of principles that drive strategy towards control and management of market risk of all institution. ITAÚ UNIBANCO HOLDING CONSOLIDATED’s market risk management strategy is aimed at balancing corporate business goals, taking into account, among other things: · Political, economic and market conditions; · Portfolio profile of ITAÚ UNIBANCO HOLDING CONSOLIDATED; · Expertise within the group to support operations in specific markets. The purpose of market risk control of ITAÚ UNIBANCO HOLDING CONSOLIDATED structure is: · Providing visibility and assurance to all executive levels that the assumption of market risks is in line with ITAÚ UNIBANCO HOLDING CONSOLIDATED risk-return objective; · Promoting a disciplined and informed discussion on the global risk profile and its evolution over time; · Increasing transparency on the way the business seeks to optimize results; · Providing early warning mechanisms in order to make the effective risk management easier, without jeopardizing the business purposes; and · Monitoring and avoiding risk concentration. 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 CONSOLIDATED, (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. 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. For a detailed vision of the accounting hedge topic, see Note 7 – 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. 3,464 and BACEN Circular nº. 3,354. The trading portfolio consists of all transactions involving financial instruments and goods, including derivatives, which are carried out with the intention of trading.

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. At June 30, 2018, ITAÚ UNIBANCO HOLDING CONSOLIDATED posted a Total VaR of R$ 491.1 million (R$ 460.8 million at June 30, 2017). Increase in Total VaR Total verified in relation to the previous year was mainly due to the increase of volatility in the Interest Rate market.

II – Credit risk ITAÚ UNIBANCO HOLDING CONSOLIDATED understands credit risk as the possibility of losses arising from the breach by the borrower, issuer or counterparty of the respective agreed-upon financial obligations, the devaluation of loan agreement due to downgrading of the borrower’s, the issuer’s, the counterparty’s risk rating, the reduction in gains or compensation, the advantages given upon posterior renegotiation and the recovery costs. There is a credit risk control and management structure, centralized and independent from the business units, that provides for operational limits and risk mitigating mechanisms, in addition for establishing processes and tools to measure, monitor and control the credit risk inherent in all products, portfolio concentrations and the impacts from potential changes in the economic environment. ITAÚ UNIBANCO HOLDING CONSOLIDATED establishes its credit policy based on internal factors, such as client rating criteria, performance of and changes in portfolio, default levels, return rates, and allocated economic capital, among others, also considering external factors, such as interest rates, market default indicators, inflation, changes in consumption, among others. To protect the institution against losses arising from loan operations, ITAÚ UNIBANCO HOLDING CONSOLIDATED considers all aspects that determine the client’s credit risk to define a provision level that is adequate with the risk incurred in each operation. For each operation, the assessment and rating of the client or economic group, the operation rating, and the possible existence of past-due amounts are taken into account and the volume of the regulatory provision is determined.

IV – Liquidity risk Liquidity risk is defined as 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 responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different horizons of time, and monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING CONSOLIDATED operates. All activities are subject to verification by the independent validation, internal control and audit areas. In compliance with Circular Letter n° 3,775 of BACEN, bank holding total assets over R$ 100 billion are required to report a standardized Liquidity Coverage Ratio (LCR) to the Central Bank of Brazil on a monthly basis as of October 2015. This ratio is calculated based on a methodology defined by the Central Bank of Brazil itself, and is in line with international guidelines of Basel. The summarized index calculation is presented in the table below. In 2018, the index minimum requirement is 90%. Further details on the LCR for the period may be accessed at www.itau.com.br/investor-relations, section Corporate Governance/ Capital and Risk Management - Pillar 3. Second quarter of 2018 Information on the Liquidity Coverage Ratio (LCR) (1) Total Adjusted Amount (2) 172,177,693 Total high-quality liquid assets (3) 101,584,392 Total potential cash outflows Liquidity Coverage Ratio (%) 169.5% (1) Corresponds to the amount calculated after the application of weighting factors and limits established by BACEN Circular nº. 3,749. (2) HQLA - High quality liquid assets: balance in the stock, which in certain cases weighted by a discount factor, of assets that remain liquid in the markets during a stress period, which can be easily converted into cash and that pose low risk. (3) Potential cash outflows calculated in standardized stress, determined by Circular nº. 3,749 (outflows), subtracted from (i) potential cash inflows calculated under standardized stress, set forth by Circular nº. 3,749 and (ii) 75% x Outflows, whichever is lower.

Those charged with governance in the Bank and its subsidiaries are responsible for overseeing the financial reporting process. 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 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 concerns. 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 and its subsidiaries to cease to continue as going concern. • Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation. • Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Consolidated to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.
