Risk and Capital Management – Pillar 3 1 Risk Management To undertake and manage risks is one of the activities of Itaú Unibanco. For this reason, the institution must have clearly established risk management objectives. In this context, the risk appetite defines the nature and the level of risks acceptable for the institution, while the risk culture guides the attitudes required to manage them. Itaú Unibanco seeks to maintain robust and company-wide risk management processes to serve as a basis for its strategic decisions intended to ensure business sustainability. These processes are in line with the guidelines of the Board of Directors and Executives who, through corporate bodies, define the institution’s global objectives, which are then translated into targets and thresholds for the business units that manage risks. Control and capital management units, in turn, support Itaú Unibanco’s management through the processes of analysis and monitoring capital and risk assessment processes. The principles that provide risk management and risk appetite fundamentals, as well as guidelines regarding the actions taken by Itaú Unibanco’s employees in their daily routines are as follows: · Sustainability and customer satisfaction: the vision of Itaú Unibanco is to be a leading bank in sustainable performance and customer satisfaction. For this reason, the institution is concerned about creating shared values for employees, customers, shareholders and society to ensure the longevity of the business. Itaú Unibanco is concerned about doing business that is good for customers and for the institution; · Risk Culture: the institution’s risk culture goes beyond policies, procedures and processes, strengthening the employees’ individual and collective responsibility to do the right thing, at the right time and in the right way, with respect for ethical business. The Risk Culture is described in item 1.2 “Risk Culture”; · Price for Risk: Itaú Unibanco operates and assumes risks in business that it knows and understands, avoids unknown risks or risks that provide no competitive advantages, and carefully assesses risk-return ratios; · Diversification: the institution has low appetite for volatility in its results. Accordingly, it operates with a diversified base of customers, products and business, seeking risk diversification and giving priority to low-risk transactions; · Operational excellence: Itaú Unibanco intends to provide agility, as well as a robust and stable infrastructure, so as to offer high quality services; · Ethics and respect for regulations: at Itaú Unibanco, ethics is non-negotiable. For this reason, the institution promotes an institutional environment of integrity, educating its employees to cultivate ethical relationships and businesses, as well as respecting the norms, and therefore caring for the institution’s reputation. On August 21, 2017, the Resolution CMN 4,557 came into force, which established the structure of risk and capital management. The resolution highlights are the implementation of a continuous and integrated risk management framework; the requirements for the definition of the Risk Appetite Statement (RAS) and the stress test program; the establishment of a Risk Committee; the indication, before BACEN, of the Chief Risk Officer (CRO); and the CRO’s roles, responsibilities and independence requirements. Itaú Unibanco complies with the best risk and capital management practices set forth in CMN Resolution 4,557; accordingly, there is no significant impact arising from its adoption. 5 Itaú Unibanco Risk and Capital Management – Pillar 3 1 Risk Management To undertake and manage risks is one of the activities of Itaú Unibanco.

Risk and Capital Management – Pillar 3 1.1 Risk Appetite In 2016, Itaú Unibanco reviewed its risk appetite policy, which was established and approved by the Board of Directors and guides the institution’s business strategy. The bank’s risk appetite is grounded on the following declaration of the Board of Directors: “We are a universal bank, operating predominantly in Latin America. Supported by our risk culture, we operate based on rigorous ethical and regulatory compliance standards, seeking high and growing results, with low volatility, by means of the long-lasting relationship with clients, correctly pricing risks, well-distributed fund-raising and proper use of capital.” Based on this declaration, the bank established five dimensions, each of which comprising a set of metrics associated with the key risks involved, combining complementary measurements and seeking a comprehensive view of its exposure: · Capitalization: establishes that Itaú Unibanco should have sufficient capital to protect against a serious recession or stress events without the need to adjust its capital structure under adverse circumstances. It is monitored by following up on the bank’s capital ratios in usual or stress situations, and debt issue ratings. · Liquidity: establishes that the institution’s liquidity should be able to support long stress periods. It is monitored by following up on liquidity ratios. · Composition of results: establishes that business will mainly focus on Latin America, where Itaú Unibanco will have a diversified range of customers and products, with low appetite for results volatility and high risk. This dimension includes business and profitability, as well as market and credit risks aspects. The metrics monitored by the bank seek to ensure, by means of exposure concentration limits such as, for example, industry sectors, quality of counterparties, countries and geographic regions and risk factors, a suitable composition of the bank’s portfolios, aiming at low volatility of results and business sustainability. · Operational risk: focuses on controlling operational risk events that may adversely impact the bank’s business strategy and operations. This control is carried out by monitoring key operational risk events and incurred losses. · Reputation: deals with risks that may impact brand value and the institution’s reputation before its customers, employees, regulators, investors and the general public. In this dimension, risks are monitored by following up on customers’ satisfaction or dissatisfaction, media exposure and observation of the institution’s conduct. The Board of Directors is responsible for approving risk appetite guidelines and limits, performing its activities with the support of the Risk and Capital Management Committee (CGRC) and the CRO. Metrics are regularly monitored and must comply with the limits defined. Monitoring is reported to the risk commissions and to the Board of Directors, guiding the use of preventive measures to ensure that exposures are within the limits provided and in line with the bank’s strategy. 6 Itaú Unibanco Risk and Capital Management – Pillar 3 1.1 Risk Appetite In 2016, Itaú Unibanco reviewed its risk appetite policy, which was established and approved by the Board of Directors and guides the institution’s business strategy.

Risk and Capital Management – Pillar 3 1.2 Risk Culture Aiming at strengthening its values and aligning the behavior of its employees with risk management guidelines, the institution adopts several initiatives to disseminate and strengthen its Risk Culture, which is based on four principles: conscious risk taking, discussion about and actions on the institution’s risks, and each and everyone’s responsibility for risk management. In addition to the bank’s policies, procedures and processes of risk management, the Risk Culture strengthens the employees’ individual and collective responsibility in understanding, identifying, measuring, managing and mitigating the risks connected to their activities, respecting the business management ethically. The institution promotes its Risk Culture by emphasizing a behavior that helps people of all company levels to undertake and manage risks in a conscious way. By disseminating these principles, the institution fosters the understanding and an open discussion about the risks, so that they are kept within the risk appetite levels established, so that each employee individually, regardless of their position, area or duties, may also assume responsibility for managing the risks of the business. Itaú Unibanco also makes some channels available for communication of operating failures, internal or external fraud, conflicts at the workplace, or cases that may result in inconveniences and/or losses for the institution or its customers. All employees or third parties are responsible for informing any problems immediately, as soon as they become aware of a situation. 1.3 Risk and Capital Governance The Board of Directors is the main body responsible for establishing the guidelines, policies and authority levels regarding risk and capital management. In turn, the CGRC provides support to the Board of Directors in the performance of their duties relating to risk and capital management. At the executive level, corporate bodies headed by Itaú Unibanco’s Chief Executive Officer (CEO) are established to manage risks and capital. Their decisions are overseen by the CGRC. Additionally, the institution has corporate bodies that perform delegated duties in the risk and capital management, and that are headed by the Vice-President of the Risk and Finance Area (ARF). Furthermore, to support this structure, ARF is structured with specialized departments. The objective is to provide independent and centralized management of the institution’s risks and capital, and ensure the accordance with the established rules and procedures. A detailed description of the structure can be found on the Consolidated Annual Report, section “Our Risk Management”. The Consolidated Annual Report can be found in the website www.itau.com.br/investor-relations, section Itaú Unibanco. Itaú Unibanco’s risk management organizational structure complies with Brazilian and international regulations in place and is aligned with the market’s best practices. Responsibilities for risk management at Itaú Unibanco are structured according to the concept of three lines of defense, namely: · in the first line of defense, the business and corporate support areas manage risks they give rise to, by identifying, assessing, controlling and reporting such risks; · in the second line of defense, an independent unit provides central control, so as to ensure that Itaú Unibanco’s risk is managed according to the risk appetite and established policies and procedures. This centralized control provides the Board and executives with a global overview of Itaú Unibanco’s exposure, to ensure correct and timely corporate decisions; · in the third line of defense, internal audit provides an independent assessment of the institution’s activities, so that senior management can see that controls are adequate, risk management is effective and institutional standards and regulatory requirements are being complied with. Itaú Unibanco uses robust automated systems for full compliance with capital regulations, as well as for measuring risks in accordance with the regulatory determinations and models in place. It also monitors adherence to the qualitative and quantitative regulators’ minimum capital and risk management requirements. 7 Itaú Unibanco Risk and Capital Management – Pillar 3 1.2 Risk Culture Aiming at strengthening its values and aligning the behavior of its employees with risk management guidelines, the institution adopts several initiatives to disseminate and strengthen its Risk Culture, which is based on four principles: conscious risk taking, discussion about and actions on the institution’s risks, and each and everyone’s responsibility for risk management.

Risk and Capital Management – Pillar 3 1.4 Risk-adjusted Compensation The Compensation guidelines are aimed at attracting, retaining and compensating on merit its employees, encouraging prudent risk exposure levels in short, medium and long-term strategies. The Compensation Committee, in accordance with the CMN Resolution No. 3,921 and the FEBRABAN’s normative SARB 017/2016 and with the reporting to the Board of Directors, is responsible for setting out the guidelines on compensation models for employees and the policy on compensation of management members of the Itaú Unibanco companies. The practices of compensation take into account the strategy of the institution, the general and specific legislation that should be adopted for each business or region of operation, and the adequate risk management over time. Variable compensation considers the current and potential risks, giving incentive to the achievement of sustainable results and discouraging decisions that involve excessive risks and inadequacies. For more information about remuneration in Itaú Unibanco, see Note 13 – “Shareholders’ Equity” in the complete Financial Statements and/or the section “Our Governance” in the Consolidated Annual Report, which is available on the website www.itau.com.br/investor-relations. 8 Itaú Unibanco Risk and Capital Management – Pillar 3 1.4 Risk-adjusted Compensation The Compensation guidelines are aimed at attracting, retaining and compensating on merit its employees, encouraging prudent risk exposure levels in short, medium and long-term strategies.

Risk and Capital Management – Pillar 3 2 Capital 2.1 Capital Management The Board of Directors is the main body in the Itaú Unibanco’s capital management and it is responsible for approving the capital management institutional policy and guidelines regarding the institution’s capitalization level. The Board is also responsible for the full approval of ICAAP (Internal Capital Adequacy Assessment Process) report, a process which is intended to assess the adequacy of Itaú Unibanco’s capital. At the executive level, corporate bodies are responsible for approving risk assessment and capital calculation methodologies, as well as reviewing, monitoring and recommending capital related documents and topics to the Board of Directors. In order to provide the Board with the data required, management reports are prepared to inform the institution’s capital adequacy, as well as capital level forecasts under usual and stress conditions. There is a structure in place for coordination and consolidation of information and related processes, which are all subject to verification by the independent validation, internal controls and audit areas. The guidelines of the institutional capital management policy can be accessed at www.itau.com.br/investor-relations, Itaú Unibanco, under Corporate Governance, Rules and Policies. 2.2 Capital Adequacy Assessment For its capital adequacy assessment process, the annual Itaú Unibanco’s procedure is as follows: · Identification of the risks to which the institution is exposed and analysis of their materiality; · Assessment of the need for capital to cover the material risks; · Development of methods for quantifying additional capital; · Quantification of capital and internal capital adequacy assessment; · Capital and Contingency Plan; · Submission of report to BACEN. By adopting a prospective stance regarding capital management, Itaú Unibanco implemented its capital management structure and its ICAAP in order to comply with National Monetary Council (CMN) Resolution 4,557, BACEN Circular 3,846 and BACEN Circular Letter 3,841. The result of the last ICAAP – dated as of December 2017 – showed that, in addition to having enough capital to face all material risks, Itaú Unibanco has a significant buffer, thus ensuring the soundness of its equity position. 2.3 Stress Testing The stress test is a process of simulating extreme economic and market conditions on Itaú Unibanco’s results and capital. The institution has been carrying out this test in order to assess its solvency in plausible scenarios of systemic crisis, as well as to identify areas that are more susceptible to the impact of stress that may be the subject of risk mitigation. For the purposes of the test, the economic research area estimates macroeconomic variables for each stress scenario. The scenarios are defined according to their importance for the institution results and the likelihood of their occurrence, and they are submitted annually to the Board of Directors for approval. Projections for the macroeconomic variables (such as GDP, the basic interest rate and inflation) and for variables in the credit market (such as raisings, lending, rates of default, margins and charges) used are based on exogenous shocks or through use of models validated by an independent area. Then, the stress scenarios adopted are used to influence the budgeted result and balance sheet, of which the risk-weighted assets and the capital and liquidity ratios are derived. The stress test is also an integral part of the ICAAP (Internal Capital Adequacy Process), the main purpose of which is to assess whether, even in severely adverse situations, the institution would have adequate levels of capital, without any impact on the development of its activities. This information enables potential risk factors in the business to be identified, and provides support for the strategic decisions of the Board of Directors, the budgeting and risk management process, as well as serving as an input for measuring risk appetite. 9 Itaú Unibanco Risk and Capital Management – Pillar 3 2 Capital 2.1 Capital Management The Board of Directors is the main body in the Itaú Unibanco’s capital management and it is responsible for approving the capital management institutional policy and guidelines regarding the institution’s capitalization level. The Board is also responsible for the full approval of ICAAP (Internal Capital Adequacy Assessment Process) report, a process which is intended to assess the adequacy of Itaú Unibanco’s capital. At the executive level, corporate bodies are responsible for approving risk assessment and capital calculation methodologies, as well as reviewing, monitoring and recommending capital related documents and topics to the Board of Directors. In order to provide the Board with the data required, management reports are prepared to inform the institution’s capital adequacy, as well as capital level forecasts under usual and stress conditions. There is a structure in place for coordination and consolidation of information and related processes, which are all subject to verification by the independent validation, internal controls and audit areas. The guidelines of the institutional capital management policy can be accessed at www.itau.com.br/investor-relations, Itaú Unibanco, under Corporate Governance, Rules and Policies. 2.2 Capital Adequacy Assessment For its capital adequacy assessment process, the annual Itaú Unibanco’s procedure is as follows: · Identification of the risks to which the institution is exposed and analysis of their materiality; · Assessment of the need for capital to cover the material risks; · Development of methods for quantifying additional capital; · Quantification of capital and internal capital adequacy assessment; · Capital and Contingency Plan; · Submission of report to BACEN. By adopting a prospective stance regarding capital management, Itaú Unibanco implemented its capital management structure and its ICAAP in order to comply with National Monetary Council (CMN) Resolution 4,557, BACEN Circular 3,846 and BACEN Circular Letter 3,841. The result of the last ICAAP – dated as of December 2017 – showed that, in addition to having enough capital to face all material risks, Itaú Unibanco has a significant buffer, thus ensuring the soundness of its equity position. 2.3 Stress Testing The stress test is a process of simulating extreme economic and market conditions on Itaú Unibanco’s results and capital. The institution has been carrying out this test in order to assess its solvency in plausible scenarios of systemic crisis, as well as to identify areas that are more susceptible to the impact of stress that may be the subject of risk mitigation. For the purposes of the test, the economic research area estimates macroeconomic variables for each stress scenario. The scenarios are defined according to their importance for the institution results and the likelihood of their occurrence, and they are submitted annually to the Board of Directors for approval. Projections for the macroeconomic variables (such as GDP, the basic interest rate and inflation) and for variables in the credit market (such as raisings, lending, rates of default, margins and charges) used are based on exogenous shocks or through use of models validated by an independent area. Then, the stress scenarios adopted are used to influence the budgeted result and balance sheet, of which the risk-weighted assets and the capital and liquidity ratios are derived. The stress test is also an integral part of the ICAAP (Internal Capital Adequacy Process), the main purpose of which is to assess whether, even in severely adverse situations, the institution would have adequate levels of capital, without any impact on the development of its activities. This information enables potential risk factors in the business to be identified, and provides support for the strategic decisions of the Board of Directors, the budgeting and risk management process, as well as serving as an input for measuring risk appetite. 9 Itaú Unibanco

Risk and Capital Management – Pillar 3 2.4 Recovery Plan The Central Bank of Brazil issued the Resolution No. 4,502, dated as of June 30, 2016, requiring a Recovery Plan for the financial institutions that are classified in Segment 1 (financial institutions with a total exposure of more than 10% of GDP, or that exert an internationally relevant activity). The purpose is to develop strategies that reestablish adequate levels of capital and liquidity, above the regulatory requirements, through appropriate strategies in the event of severe stress shocks in the institutions. Accordingly, each institution would be able to preserve its financial feasibility at the same time as it protects the National Financial System. The Recovery Plan report is reviewed and reported to BACEN annually, so as to ensure that the strategies remain up to date and feasible in the event of organizational, competitive or systemic changes. As a result, the Recovery Plan ensures that, even at times of severe stress, which are extremely unlikely to occur, Itaú Unibanco will have strategies for generating sufficient resources for the sustainable maintenance of its critical activities and essential services, without damaging its customers, the financial system or the other participants in the markets where it operates. 10 Itaú Unibanco Risk and Capital Management – Pillar 3 2.4 Recovery Plan The Central Bank of Brazil issued the Resolution No. 4,502, dated as of June 30, 2016, requiring a Recovery Plan for the financial institutions that are classified in Segment 1 (financial institutions with a total exposure of more than 10% of GDP, or that exert an internationally relevant activity).

Risk and Capital Management – Pillar 3 2.5 Capital Requirements and Capital Composition Itaú Unibanco’s minimum capital requirements are expressed as ratios of the capital available – relating the Total Capital (1) (Referential Equity) to the risk-weighted assets (RWA). These ratios follow the set of resolutions and circulars disclosed by BACEN that implemented, in Brazil, the global capital requirement standards known as Basel III. The Total Capital is the sum of three items, namely: · Common Equity Tier I: sum of social capital, reserves and retained earnings, less deductions and prudential adjustment; · Additional Tier I Capital: consists of instruments of a perpetual nature, which meet eligibility requirements. Together with Common Equity Tier I it makes up Tier I; · Tier II: consists of subordinated debt instruments with defined maturity dates that meet eligibility requirements. Together with Common Equity Tier I and Additional Tier I Capital, it makes up Total Capital. The Total Capital, Tier I Capital and Common Equity Tier I Capital ratios are calculated on a consolidated basis, applied to (2) the institutions included in the Prudential Conglomerate , which comprises not only financial institutions but also collective financing plans (“consórcios”), payment entities, factoring companies or companies that directly or indirectly assume credit risk, and investment funds in which the institution retains substantially all risks and benefits. In order to calculate the minimum capital requirements, the total RWA is determined as the sum of the risk-weighted asset amounts for credit, market, and operational risks. Credit, market and operational risks approaches are treated as described in section “2.6 Risk-Weighted Assets (RWA)”. The minimum Total Capital ratio required is 8.0% as from January 1st, 2019. The BACEN rules call for Additional Capital Buffers (ACP), corresponding to the sum of the components ACPConservation, ACPCountercyclical and ACPSystemic, which, along with the requirements mentioned, increase capital requirement over time, as provided for in CMN Resolution 4,193. st Basel III - Implementation Schedule From January 1 (2) 2018 2019 Common Equity Tier I 4.5% 4.5% Tier I 6.0% 6.0% Total Capital 8.625% 8.0% Additional Capital Buffers (ACP) 2.375% 3.5% conservation 1.875% 2.5% (1) countercyclical 0% 0% systemic 0.5% 1.0% Common Equity Tier I + ACP 6.875% 8.0% Total Capital + ACP 11.0% 11.5% Prudential adjustments deductions 100% 100% (1) The countercyclical capital buffer is fixed by the Financial Stability Committee (Comef) based on discussions about the pace of credit expansion (BACEN Communication No. 30,371/17), and currently is set to zero (BACEN Communication No. 33,240/19). Should the requirement increase, the new percentage takes effect twelve months after the announcement. (2) Minimum requirements valid from 1 January, 2019 onwards. Basel III also redefined the requirements for qualifying the instruments eligible for Tier I and Tier II Capital, which in Brazil are regulated by CMN Resolution 4,192. This reform included a phase-out schedule for instruments currently included in capital, which were issued before the rule came into effect and which do not fully meet the new requirements.

Risk and Capital Management – Pillar 3 2.8.1 IRRBB - Interest Rate Risk in the Banking Book BACEN’s (Central Bank of Brazil) Circular 3,876, published in January 2018, states on methodologies and procedures for evaluation of the capital adequacy, held to cover interest rates risk from instruments held in the banking book. For the purposes of this Circular, are defined: • ∆EVE (Delta Economic Value of Equity) is defined as the difference between the present value of the sum of repricing flows of instruments subject to IRRBB in a base scenario, and the present value of the sum of repricing flows of the same instruments in an interest-rate shocked scenario; • ∆NII (Delta Net Interest Income) is defined as the difference between the result of financial intermediation of instruments subject to IRRBB in a base scenario, and the result of financial intermediation of the same instruments in an interest-rate shocked scenario. The sensibility analysis introduced here are just a static evaluation of the portfolio interest rate exposure, and, therefore, don´t consider the dynamic management of the treasury desk and risk control areas, which hold the responsibility for measures to mitigate risk under an adverse situation, minimizing significant losses. Moreover, it is highlighted, though, the results presented do not translate into accountable or economic results for certain, because this analysis has, only, an interest rate risk disclosure purpose and to demonstrate the principle protection actions, considering the instruments fair value, apart from any accounting practices adopted by Itaú Unibanco. The institution uses an internal model to measure ∆EVE and ∆NII. ∆EVE results do not represent immediate impact in the stockholders’ equity. Meanwhile, ∆NII results indicate potential volatility in the projected interest rates results. In compliance with the circular 3,876, the following demonstrates qualitative and quantitative details of risk management for IRRBB in Itaú Unibanco. Framework and Treatment Interest rate risk in the banking book refers to the potential risk of impact on capital sufficiency and/or on the results of financial intermediation due to adverse movements in interest rates, taking into account the principal flows of instruments held in the banking book. The main point of assets and liabilities management is to maximize the risk-return ratio of positions held in the banking book, taking into account the economic value of these assets/liabilities and the impact on actual and future bank’s results. The interest rate risk managing on transactions held in the banking book occurs within the governance and hierarchy of decision-making bodies and under a limits structure and alerts approved specifically for these purpose, which is sensitive due to different levels and classes of market risk. The management structure of IRRBB has it owns risk policies and controls intended to ensure adherence to the bank’s risk appetite. The IRRBB framework has granular management limits for several other risk metrics and consolidated limits for ∆EVE and ∆NII results, besides the limits associated with stress tests. The asset and liability management unit is responsible for managing timing mismatches between asset and liability flows, and minimizes interest rate risk by through strategies as economic hedge and accounting hedge. All the models associated with IRRBB have a robust independent validation process and are approved by a CTAM (Technical Model Assessment Commission). In addition, all the models and processes are assessed by internal audit. The interest rate risk framework in the banking book uses management measurements that are calculated daily for limit control. The ∆EVE and ∆NII metrics are calculated according to the risk appetite limits and the other risk metrics in terms of management risk limits. In the process of managing interest rate risk of the banking book, transactions subject to automatic options are calculated according to internal market models which split the products, as far as possible, into linear and non-linear payoffs. The linear payoffs are treated similarly to any other instruments without options, and for non-linear payoffs an additional value is computed and added on the ∆EVE and ∆NII metrics. In general terms, transactions subject to behavioral options are classified as deposits with no contractual maturity date defined or products subject to early repayment. Non-maturity deposits are classified according to their nature and stability to guarantee compliance with regulatory limits.

Risk and Capital Management – Pillar 3 pre-payment, using the historical dataset to calibrate its parameters. The instruments flows with homogeneous characteristics are adjusted by specific models to reflect, in the most appropriate way, the repricing flows of the instruments. The banking book consists of asset and liability transactions originating in different commercial channels (retail and wholesale) of Itaú Unibanco. The market risk exposures inherent in the banking book consists of various risk factors, which are primary components of the market in price formation. IRRBB also includes hedging transactions intended to minimize risks deriving from strong fluctuations of market risk factors and their accounting asymmetries. Market risk generated from structural mismatches is managed by a variety of financial instruments, such as exchange- traded and over-the-counter derivatives. In some cases, operations using derivative financial instruments can be classified as accounting hedges, depending on their risk and cash flow characteristics. In these cases, the supporting documentation is analyzed to enable the effectiveness of the hedge and other changes in the accounting process to be continuously monitored. The accounting and administrative procedures for hedging are defined in BACEN Circular 3,082. The IRRBB model includes a series of premises: • ∆EVE and ∆NII are measured on the basis of the cash flows of the banking book instruments, broken down into their risk factors to isolate the effect of the interest rate and the spread components; • For non-maturity deposits, the models are classified according to their nature and stability and distributed over time considering the regulatory limits; • The institution uses survival analysis models to handle credit transactions subject to prepayment, and empirical models for transactions subject to earlyredemption; • The medium-term repricing attributed to non-maturity deposits is defined as 1.4 years; • The maximum-term repricing attributed to non-maturity deposits is defined as 34 years The article 39 of the circular defines the need to publish ∆EVE and ∆NII, using the standard shock scenarios described in article 11. Itaú Unibanco has opted to an additional disclosure of the metrics above, considering the internal scenarios, because of the understanding that the standard approach shocks and is application are too conservative. The institution understands that is owns internal scenarios, defined by statistical methodologies, which consider the interest rate historical distribution behavior represent in a more appropriate way the potential risk embedded in the interest rates volatility. Additionally, internal model is more adherent with the way Itaú Unibanco manages its own risks.

Risk and Capital Management – Pillar 3 5 Credit Risk 5.1 Framework and Treatment Itaú Unibanco defines credit risk as the risk of loss associated with: failure by a borrower, issuer or counterparty to fulfill their respective financial obligations as defined in the contracts; value loss of credit agreements resulting from deterioration of the borrower’s, issuer’s or counterparty’s credit rating; reduction of profits or income; benefits granted upon subsequent renegotiations; or debt recovery costs. The management of credit risk is intended to preserve the quality of the loan portfolio at levels compatible with the institution’s risk appetite for each market segment in which we operate. The governance of credit risk is managed through corporate bodies, which report to the Board of Directors or to the Itaú Unibanco executive structure. Such corporate bodies act primarily by assessing the competitive market conditions, setting the credit limits for the institution, reviewing control practices and policies, and approving these actions at the respective authority levels. The risk communication and reporting process, including disclosure of institutional and supplementary policies on credit risk management, are responsibility of this structure. Itaú Unibanco manages the credit risk to which it is exposed during the entire credit cycle, from before approval, during the monitoring process and up to the collection or recovery phase. There is a credit risk management and control structure, centralized and independent of the business units and defines operational limits, risk mitigation mechanisms and processes, and instruments to measure, monitor and control the credit risk inherent to all products, portfolio concentrations and impacts to potential changes in the economic environment. The credit’s portfolio, policies and strategies are continuously monitored so as to ensure compliance with the rules and laws in effect in each country. The key assignments of the business units are (i) monitoring of the portfolios under their responsibility, (ii) granting of credit, taking into account current approval levels, market conditions, the macroeconomic prospects, and changes in markets and products, and (iii) credit risk management aimed at making the business sustainable. Itaú Unibanco’s credit policy is based on internal factors, such as: client rating criteria, performance and evolution of the portfolio, default levels, return rates and allocated economic capital, among others; and also take into account external factors such as: interest rates, market default indicators, inflation and changes in consumption, among others. With respect to individuals, small and medium companies, credit ratings are assigned based on statistical application (in the early stages of relationship with a customer) and behavior score (used for customers with whom Itaú Unibanco already has a relationship) models. For large companies, classification is based on information such as the counterparty’s economic and financial situation, its cash-generating capacity, and the business group to which it belongs, the current and prospective situation of the economic sector in which it operates. Credit proposals are analyzed on a case-by-case basis through the approval governance. The concentrations are monitored continuously for economic sectors and largest debtors, allowing preventive measures to be taken to avoid the violation of the established limits. Itaú Unibanco also strictly controls credit exposure to clients and counterparties, acting to reserve occasional limit breaches. In this sense, contractual covenants may be used, such as the right to demand early payment or require additional collateral. To measure credit risk, Itaú Unibanco takes into account the probability of default by the borrower, issuer or counterparty, the estimated amount of exposure in the event of default, past losses from default and concentration of borrowers. Quantifying these risk components is part of the lending process, portfolio management and definition of limits. The models used by Itaú Unibanco are independently validated, to ensure that the databases used in constructing the models are complete and accurate, and that the method of estimating parameters is adequate. Itaú Unibanco counts on a specific structure and processes aimed at ensuring that the country risk is managed and controlled, described in item “9 Other Risks”. In compliance with CMN Resolution 3,721, the document “Public Access Report - Credit Risk,” which describes the guidelines established in the institutional ruling on credit risk control, can be viewed on the website www.itau.com.br/investor-relations, section Itaú Unibanco, under Corporate Governance, Rules and Policies. 31 Itaú Unibanco Risk and Capital Management – Pillar 3 5 Credit Risk 5.1 Framework and Treatment Itaú Unibanco defines credit risk as the risk of loss associated with: failure by a borrower, issuer or counterparty to fulfill their respective financial obligations as defined in the contracts; value loss of credit agreements resulting from deterioration of the borrower’s, issuer’s or counterparty’s credit rating; reduction of profits or income; benefits granted upon subsequent renegotiations; or debt recovery costs.

Risk and Capital Management – Pillar 3 Mitigating Instruments Itaú Unibanco uses guarantees aiming at increasing resilience in operations with credit risk. The using guarantees can be personal guarantees, secured guarantees, legal structures with mitigating power and netting arrangements. To be considered as credit risk mitigation instrument, the guarantees need to comply with requirements and determinations of the regulations that govern them whether internal or external and be legally valid (effective), enforceable and regularly evaluated. In the case of secured guarantees, legal structures with mitigating effects and netting arrangements, mitigation depends on established methods approved by the business units responsible for managing credit risk and the central credit risk control area. Such methods take into account factors relating to the legal enforcement of the security, the costs involved in the process and the expected execution value, considering market volatility and liquidity. Additionally, concentration of these instruments in the credit portfolio is monitored on a regular basis. Lastly, personal guarantees and the purchase of protection through credit derivatives mitigate credit risk by substituting the taker’s risk parameters with those of the guarantor. Itaú Unibanco also uses credit derivatives to mitigate the credit risk of its portfolios of 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. In order to use each type of mitigating instrument to calculate the regulatory capital, Itaú Unibanco compares the specifications of the instrument to the requirements provided for in the prudential regulations in force. In this process, the institution assesses the coverage level of mitigated exposures, the risk weights (FPR) of the mitigation instruments, maturity terms, and currencies of denomination or indexation, among other aspects. In the case of credit transactions mitigated by fiduciary transfer or 1st-degree mortgage on residential property, mitigation is definite by the FPR applied to the exposure, as provided for in BACEN Circular 3,644. Therefore, these transactions are not subject to the provisions set forth in BACEN Circular 3,809. The table below presents the total amount covered by mitigation instruments (collaterals and guarantees), calculated in accordance with BACEN Circular 3,809. As provided for in the Circular, at the beginning of each fiscal year, the institution must choose between the Simple or Comprehensive Approach for credit risk mitigation.

Risk and Capital Management – Pillar 3 Counterparty Credit Risk Counterparty credit risk is the possibility of noncompliance with obligations related to the settlement of transactions that involve the trading of financial assets with a bilateral risk. It encompasses of derivative financial instruments, settlement pending transactions, securities lending and repurchase transactions. Itaú Unibanco has well-defined rules for calculating its exposure, and the models designed are used both for controlling the use of counterparty limits and for allocating capital. For derivatives, Itaú Unibanco uses the potential credit risk (PCR) too, interpreted as the value of the potential financial exposure that a transaction can attain upon maturity. After the maturity of a derivatives contract, Itaú Unibanco’s practice is to set up a provision for the amounts receivable on these instruments. Netting agreements are defined by CMN Resolution 3,263 and, as from January 2017, Itaú Unibanco has been considering this resolution in the calculation of its regulatory capital, in accordance with BACEN Circular 3,809. According to BACEN Circular 3,644, for the calculation of the net global exposure to the counterparty credit risk arising from operations with derivative financial instruments, the application of the Future Potential Exposure Factor (FEPF) is considered.

It encompasses of derivative financial instruments, settlement pending transactions, securities lending and repurchase transactions. Itaú Unibanco has well-defined rules for calculating its exposure, and the models designed are used both for controlling the use of counterparty limits and for allocating capital. For derivatives, Itaú Unibanco uses the potential credit risk (PCR) too, interpreted as the value of the potential financial exposure that a transaction can attain upon maturity. After the maturity of a derivatives contract, Itaú Unibanco’s practice is to set up a provision for the amounts receivable on these instruments. Netting agreements are defined by CMN Resolution 3,263 and, as from January 2017, Itaú Unibanco has been considering this resolution in the calculation of its regulatory capital, in accordance with BACEN Circular 3,809. According to BACEN Circular 3,644, for the calculation of the net global exposure to the counterparty credit risk arising from operations with derivative financial instruments, the application of the Future Potential Exposure Factor (FEPF) is considered. In the case of unsettled operations, the application of the Unsettled Operation Credit Conversion Factor (FCL) is considered.

It should be noted that the portion of RWA attributable to securitization exposure did not exceed 5% of its total on CPAD March 31, 2019. Itaú Unibanco ascertains its gains and losses with the securitization process taking into account its different activities as originator or investor, in other words, the participant that assigns portfolios for securitization purposes, and the trader of securitized assets, respectively. As originator, gains and losses are calculated as the difference between the sum received for assets transferred to the securitizing institutions and the book value of the portfolio. As investor, the calculation takes into account the difference between the sale amount and the book value of the securitized paper. Gains and losses on securitization are disclosed when they are material. Credit Derivatives Itaú Unibanco buys and sells credit protection in order to meet the needs of its customers. 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.

Risk and Capital Management – Pillar 3 6 Market Risk 6.1 Framework and Treatment Market risk is the possibility of losses resulting from fluctuations in the market values of positions held by a financial institution, including the risk of operations subject to variations in foreign exchange rates, interest rates, price indexes, equity and commodity prices. Itaú Unibanco’s institutional policies and general market risk management framework are in line with the principles of CMN Resolution 3,464, and subsequent amendments. These principles guide the approach to market risk control across the institution. Itaú Unibanco’s market risk management strategy is aimed at balancing corporate business goals, taking into account, among other factors: · Political, economic and market conditions; · The profile of Itaú Unibanco´s portfolio; and · Capacity to act in specific markets. The key principles underlying Itaú Unibanco’s market risk control structure are as follows: · Provide visibility and comfort for all senior management levels that market risks assumed must be in line with Itaú Unibanco risk-return objectives; · Provide disciplined and informed dialogue on the overall market risk profile and its evolution over time; · Increase transparency as to how the business works to optimize results; · Provide early warning mechanisms to facilitate effective risk management, without obstructing the business objectives; and · Monitor and avoid concentration of risks. Market risk is controlled by an area independent of the business units, which is responsible for the daily activities: (i) measuring and assessing risk, (ii) monitoring stress scenarios, limits and alerts, (iii) applying, analyzing and stress testing scenarios, (iv) reporting risk to the individuals responsible in the business units, in compliance with Itaú Unibanco´s governance, (v) monitoring the measures needed to adjust positions and/or risk levels to make them viable, and (vi) supporting the secure launch of new financial products. The CMN has regulations that establish the segregation of exposure to market risk into risk factors, such as: interest rates, exchange rates, stocks and commodities. Brazilian inflation indices are also treated as a group of risk factors and follow the same structure of limits governance. The structure of limits and alerts is in alignment with the board of directors' guidelines, being reviewed and approved on an annual basis. This structure extends to specific limits and is aimed at improving the process of risk monitoring and understanding as well as preventing risk concentration. Limits and alerts are calibrated based on projections of future balance sheets, stockholders’ equity, liquidity, complexity and market volatility, as well as the Itaú Unibanco’s risk appetite. In an attempt to fit the transactions into the defined limits, Itaú Unibanco hedges its client transactions and proprietary positions, including investments overseas. Derivatives are the most commonly used instruments for carrying out these hedging activities, and can be characterized as either accounting or economic hedge, both of which are governed by institutional regulations at Itaú Unibanco. Hedge accounting considerations are presented in detail in Note 5f V – “Accounting hedge” to the Complete Financial Statements, that can be found on the website www.itau.com.br/investor-relations. Market risk management framework categorizes transactions as part of either the Trading Book or the Baking Book, in accordance with general criteria established by CMN Resolution 3,464 and BACEN Circular 3,354. Trading Book is composed of all trades with financial and commodity instruments (including derivatives) undertaken with the intention of trading. Banking Book is predominantly characterized by portfolios originated from the banking business and operations related to balance sheet management, are intended to be either held to maturity, or sold in the medium and in the long term. Market risk management is based on the following key metrics: · Value at Risk (VaR): a statistical metric that quantifies the maximum potential economic loss expected in normal market conditions, considering a defined holding period and confidence interval; 42 Itaú Unibanco Risk and Capital Management – Pillar 3 6 Market Risk 6.1 Framework and Treatment Market risk is the possibility of losses resulting from fluctuations in the market values of positions held by a financial institution, including the risk of operations subject to variations in foreign exchange rates, interest rates, price indexes, equity and commodity prices.

Risk and Capital Management – Pillar 3 · Losses in Stress Scenarios (Stress Testing): a simulation technique to evaluate the impact, in the assets, liabilities and derivatives of the portfolio, of various risk factors in extreme market situations (based on prospective and historic scenarios); · Stop Loss: metrics that trigger a management review of positions, if the accumulated losses in a given period reach specified levels; · Concentration: cumulative exposure of certain financial instrument or risk factor calculated at market value ( MtM - Mark to Market ); and · Stressed VaR: statistical metric derived from VaR calculation, aimed at capturing the biggest risk in simulations of the current trading portfolio, taking into consideration the observable returns in historical scenarios of extreme volatility. In addition to the risk metrics described above, sensitivity and loss control measures are also analyzed. They include: · Gap Analysis: accumulated exposure of the cash flows by risk factor, which are marked-to-market and positioned by settlement dates; · Sensitivity (DV01 – Delta Variation Risk): impact on the market value of cash flows when a 1 basis point change is applied to current interest rates or on the index rates; and · Sensitivities to Various Risk Factors (Greeks): partial derivatives of a portfolio of options on the prices of the underlying assets, implied volatilities, interest rates and time. Itaú Unibanco uses proprietary systems to measure the consolidated market risk. The processing of these systems takes place 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. The document that details the market risk control institutional policy is on the Investor Relations website www.itau.com.br/investor-relations, section Itaú Unibanco, under Corporate Governance, Rules and Policies. 6.2 Portfolio Analysis Interest rate risk in the banking book Interest rate risk is the potential loss associated with variations in these rates in the market in relation to indexer mismatches, maturities and between investments and funding. The methodology adopted involves marking-to-market of the various products, calculating the sensitivity to variations in interest rates, and the value at risk by historical simulation (VaR) as well as stress tests throughout the entire portfolio, as determined by Itaú Unibanco's institutional regulations. In managing the interest rate risk of the loan portfolios that show material early settlements, Itaú Unibanco adjusts the original maturities of transactions, which speeds up the reduction in the originally contracted payment flows so as to better reflect clients' expected behavior. Likewise, the balances of products with no definite expiry date, such as demand deposits and savings accounts, are included in the statistics on the basis of past and seasonal experience. The core portion is distributed over time, thus generating an exposure to changes in interest rates, pursuant to internally approved methodologies. The table below shows the sensitivity of the amount of the banking book positions to changes in interest rate curves, using the methodology and stress scenarios adopted.

Risk and Capital Management – Pillar 3 Stress Testing In addition to using VaR, Itaú Unibanco analyzes the risk in extreme scenarios under a wide range of different stress testings, so as to identify significant losses that could occur in extreme market conditions. This scenarios are based on past crises or on predetermined shocks in the risk factors. One factor that has a major bearing on the test results is the correlation between the assets and the respective risk factors, and this effect is simulated in various ways in the different scenarios tested. In order to identify its greatest risks and to assist in decision-making by the treasury department and by the senior management, the results of the stress tests are assessed by means of risk factors as well as in a consolidated way. Backtesting The effectiveness of the VaR model is validated by the use of backtesting techniques, comparing daily hypothetical and effective results with the estimated daily VaR, according to BACEN Circular 3,646. The number of exceptions to the VaR pre- established limits should be consistent, within an acceptable margin, with the hypothesis of 99% confidence interval, considering a range of 250 business days. Confidence intervals of 97.5% and 95%, and periods of 500 and 750 business days, respectively are also considered. The backtesting analysis presented below considers the ranges suggested by the Basel Committee on Banking Supervision (BCBS). The ranges are divided into: · Green (0 to 4 exceptions): backtesting results that do not suggest any problem with the quality or accuracy of the adopted models; · Yellow (5 to 9 exceptions): intermediate range group, which indicates an early warning monitoring and may indicate the need to review the model; and · Red (10 or more exceptions): need for improvement actions. The Backtesting presented one exception in relation to the effective and hypothetical results in the period. Pricing of Financial Instruments To price its portfolios, Itaú Unibanco uses, where possible, price quotes seen in financial markets and published by reliable external sources, or, if quotes are not available from specialized sources, estimates from pricing models representing the fair value of its positions. The pricing parameters used by Itaú Unibanco include interest rates, foreign exchange rates, the prices of securities, equities, commodities, derivatives contracts, indices, and volatilities. Prices are calculated by the pricing area, and are independently validated from price information, volatility curves and surfaces (IPV – Independent price validation), to ensure that the information is consistent and accurate. 46 Itaú Unibanco Risk and Capital Management – Pillar 3 Stress Testing In addition to using VaR, Itaú Unibanco analyzes the risk in extreme scenarios under a wide range of different stress testings, so as to identify significant losses that could occur in extreme market conditions. This scenarios are based on past crises or on predetermined shocks in the risk factors. One factor that has a major bearing on the test results is the correlation between the assets and the respective risk factors, and this effect is simulated in various ways in the different scenarios tested. In order to identify its greatest risks and to assist in decision-making by the treasury department and by the senior management, the results of the stress tests are assessed by means of risk factors as well as in a consolidated way. Backtesting The effectiveness of the VaR model is validated by the use of backtesting techniques, comparing daily hypothetical and effective results with the estimated daily VaR, according to BACEN Circular 3,646. The number of exceptions to the VaR pre- established limits should be consistent, within an acceptable margin, with the hypothesis of 99% confidence interval, considering a range of 250 business days. Confidence intervals of 97.5% and 95%, and periods of 500 and 750 business days, respectively are also considered.

Risk and Capital Management – Pillar 3 7 Operational Risk 7.1 Framework and Treatment Operational risk is defined as the possibility of losses arising from failure, deficiency or inadequacy of internal process, people or systems or from external events that affect the achievement of strategic, tactical or operational objectives. It includes legal risk associated with inadequacy or deficiency in contracts signed by the institution, as well as penalties due to noncompliance with laws and punitive damages to third parties arising from the activities undertaken by the institution. Itaú Unibanco internally classifies its risk events in: · Internal fraud; · External fraud; · Labor claims and deficient security in the workplace; · Inadequate practices related to clients, products and services; · Damages to own physical assets or assets in use by Itaú Unibanco; · Interruption of Itaú Unibanco’s activities; · Failures in information technology (IT) systems, processes or infrastructure; · Failures in the performance, compliance with deadlines and management of activities at Itaú Unibanco. Operational risk management includes conduct risk, which is subject to mitigating procedures to assess product design (suitability) and incentive models. The inspection area is responsible for fraud prevention. Irrespective of their origin, specific cases may be handled by risk committees and integrity and ethics committees. Itaú Unibanco has a governance process that is structured through forums and corporate bodies composed of senior management, which report to the Board of Directors, with well-defined roles and responsibilities in order to segregate the business and management and control activities, ensuring independence between the areas and, consequently, well-balanced decisions with respect to risks. This is reflected in the risk management process carried out on a decentralized basis under the responsibility of the business areas and by a centralized control carried out by the internal control, compliance and operational risk department, by means of methodologies, training courses, certification and monitoring of the control environment in an independent way. The managers of the executive areas use corporate methods constructed and made available by the internal control, compliance and operational risk area. Among the methodologies and tools used are the self-evaluation and the map of the institution’s prioritized risks, the approval of processes, products, and system development products and projects, the monitoring of key risk indicators that and the database of operational losses, guaranteeing a single conceptual basis for managing processes, systems, projects and new products and services. Within the governance of the risk management process, regularly, the consolidated reports on risk monitoring, controls, action plans and operational losses are presented to the business area executives. In line with CMN Resolution 4,557, the document “Public Report – Integrated Management of Operational Risk /Internal Controls/Compliance”, summarized version of the institutional operational risk management policy can be found on the website www.itau.com.br/investor-relations, section Itaú Unibanco, under Corporate Governance, Rules and Policies. 47 Itaú Unibanco Risk and Capital Management – Pillar 3 7 Operational Risk 7.1 Framework and Treatment Operational risk is defined as the possibility of losses arising from failure, deficiency or inadequacy of internal process, people or systems or from external events that affect the achievement of strategic, tactical or operational objectives.

Risk and Capital Management – Pillar 3 7.2 Crisis Management and Business Continuity Itaú Unibanco's Business Continuity Program is designed to anticipate and respond at an acceptable level to events that may interrupt its essential activities. It establishes the Business Continuity Plan (BCP), which consists of modular procedures that are available for use in the event of incidents. The descriptions/characteristics of the existing plans are: · Disaster Recovery: it aims to ensure the availability and integrity of Information Technology resources and communication in the event of a failure in the primary Data Center to maintain the processing of critical systems; · Workplace Contingency: alternative facilities to perform the activities in the event the administrative buildings become unavailable; · Operational Contingency: alternatives to carry out critical processes whether they are systemic, procedural or emergency responses. In order to assess the efficiency of the contingency actions in the face of the interruption scenarios described in the plans and identify improvement points, tests are carried out at intervals that vary according to the plan, at least once a year. In order to keep the continuity solutions aligned with the business requirements (processes, minimum resources, legal requirements, etc) the Program applies the following tools to assess the institution: - Business Impact Analysis (BIA): evaluates the criticality and resumption requirement of the processes that support the delivery of products and services. - Threats and Vulnerabilities Analysis (AVA): identification of threats near to Itaú Unibanco’s buildings. In addition, the institution has a Crisis Management Program, which is aimed at managing business interruption events, natural disasters, impacts of an environmental, social, and infrastructure/operational (including information technology) or of any other nature that jeopardize the image and reputation and/or viability of Itaú Unibanco's processes with its employees, clients, strategic partners and regulators, with timely and integrated responses. 48 Itaú Unibanco Risk and Capital Management – Pillar 3 7.2 Crisis Management and Business Continuity Itaú Unibanco's Business Continuity Program is designed to anticipate and respond at an acceptable level to events that may interrupt its essential activities.

Risk and Capital Management – Pillar 3 7.3 Independent Validation of Risk Models Itaú Unibanco validates the processes and risk models independently. This is done by a department which is separate from the business and risk control areas, to ensure that its assessments are independent. The validation method, defined in an internal policy, meets regulatory requirements such as those of BACEN Circulars 3,646 and 3,674. The validation stages include: · Verification of mathematical and theoretical development of the models; · Qualitative and quantitative analysis of the models, including the variables, construction of an independent calculator and the use of appropriate technical; · When applicable, comparison with alternative models and international benchmarks; · Histhorical Backtesting of the model; · The correct implementation of the models in the systems used. Additionally, the validation area assesses the stress testing program. The performance of the independent validation area and the validation of the processes and models are assessed by Internal Audit and reported to the specific senior management committees. Action plans are prepared to address opportunities identified during the independent validation process, and are monitored by the 3 lines of defense and by senior management until the conclusion. 49 Itaú Unibanco Risk and Capital Management – Pillar 3 7.3 Independent Validation of Risk Models Itaú Unibanco validates the processes and risk models independently.

Risk and Capital Management – Pillar 3 Itaú Unibanco has a structured flow for addressing rules, which involves several areas, covering the stages of recognition and researches, distribution of regulatory environment changes and the monitoring of action plans for regulatory compliance, all of which are established in internal policies. This structured process includes the following actions: (i) to understand the changes in the regulatory environment; (ii) to monitor regulatory trends; (iii) to care for the relationship between the institution and the regulator, self-regulatory bodies and the representation entity; (iv) to monitor action plans on regulatory or self-regulatory compliance; (v) to coordinate a program to comply with significant norms, such as Integrity and Ethics; and (vi) to report regulatory issues in Operational and Compliance Risk forums, according to the structure of committees established in internal policies. Model Risk The model risk arises from the incorrect development or maintenance of models, such as mistaken assumptions, and inappropriate use or application of the model. The use of models can lead to decisions that are more accurate and therefore it is a major practice in the institution. The models have supported strategic decisions in several contexts, such as credit approval, pricing, volatility curve estimation, calculation of capital, among others. Due to the increasing use of models, driven by the application of new technologies and the expansion of data use, Itaú Unibanco has improved its governance in relation to its development and monitoring, through the definition of guidelines, policies and procedures aimed at assuring the quality and mitigation of the associated risks. Country Risk The country risk is the risk of losses related to non-compliance with obligations in connection with borrowers, issuers, counterparties or guarantors, as a result of political-economic and social events or actions taken by the government of the country where the borrower, issuer, counterparty or guarantor is located. Itaú Unibanco has a specific structure for the management and control of country risk, consisting of corporate bodies and dedicated teams, with responsibilities defined in policies. The institution has a structured and consistent procedure for managing and controlling country risk, including :(i) establishment of country ratings; (ii) determination of limits for countries; (iii) monitoring the use of limits. Business and Strategy Risk Business and strategy risk is the risk of a negative impact on the results or capital as a consequence of a faulty strategic planning, the making of adverse strategic decisions, the inability of Itaú Unibanco to implement the proper strategic plans and/or changes in its business environment. Itaú Unibanco has implemented many mechanisms that ensure that both the business and the strategic decision-making processes follow proper governance standards, have the active participation of executives and the Board of Directors, are based on market, macroeconomic and risk information and are aimed at optimizing the risk-return ratio. Decision-making and the definition of business and strategy guidelines, count on the full engagement of the Board of Directors, primarily through the Strategy Committee, and of the executives, through the Executive Committee. In order to handle risk adequately, Itaú Unibanco has governance and processes to involve the ARF in business and strategy decisions, so as to ensure that risk is managed and decisions are sustainable in the long term. They are: (i) qualifications and incentives of board members and executives; (ii) budgetary process; (iii) product assessment; (iv) evaluation and prospecting of proprietary mergers and acquisitions; and (v) a risk appetite framework which, for example, restricts the concentration of credit and exposure to specific and material risks. Reputational Risk Itaú Unibanco understand reputational risk as the risk arising from internal practices, risk events and external factors that may generate a negative perception of the institution among clients, counterparties, stockholders, investors, supervisors, commercial partners, among others, resulting in impacts on the value of the brand and financial losses, in addition to adversely affecting Itaú Unibanco’s capability to maintain existing commercial relations, start new businesses and continue to have access to financing sources. The institution believes that its reputation is extremely important for achieving its long-term goals and this is why the institution tries to align its speech with ethical and transparent practice and work, which is essential to raise the confidence of Itaú Unibanco’s stakeholders. Itaú Unibanco’s reputation depends on its strategy (vision, culture and skills) and derives from direct or indirect experience of the relationship between Itaú Unibanco and its stakeholders. 55 Itaú Unibanco Risk and Capital Management – Pillar 3 Itaú Unibanco has a structured flow for addressing rules, which involves several areas, covering the stages of recognition and researches, distribution of regulatory environment changes and the monitoring of action plans for regulatory compliance, all of which are established in internal policies.

They are: (i) qualifications and incentives of board members and executives; (ii) budgetary process; (iii) product assessment; (iv) evaluation and prospecting of proprietary mergers and acquisitions; and (v) a risk appetite framework which, for example, restricts the concentration of credit and exposure to specific and material risks. Reputational Risk Itaú Unibanco understand reputational risk as the risk arising from internal practices, risk events and external factors that may generate a negative perception of the institution among clients, counterparties, stockholders, investors, supervisors, commercial partners, among others, resulting in impacts on the value of the brand and financial losses, in addition to adversely affecting Itaú Unibanco’s capability to maintain existing commercial relations, start new businesses and continue to have access to financing sources. The institution believes that its reputation is extremely important for achieving its long-term goals and this is why the institution tries to align its speech with ethical and transparent practice and work, which is essential to raise the confidence of Itaú Unibanco’s stakeholders. Itaú Unibanco’s reputation depends on its strategy (vision, culture and skills) and derives from direct or indirect experience of the relationship between Itaú Unibanco and its stakeholders. 55 Itaú Unibanco

Risk and Capital Management – Pillar 3 Since the reputational risk directly or indirectly permeates all operations and processes of the institution, Itaú Unibanco’s governance is structured in a way to ensure that potential reputational risks are identified, analyzed and managed still in the initial phases of its operations and analysis of new products. The treatment given to reputational risk is structured by means of many processes and internal initiatives, which, in turn, are supported by internal policies, and their main purpose is to provide mechanisms for the monitoring, management, control and mitigation of the main reputational risks. Among them are (i) risk appetite statement; (ii) process for the prevention and fight against unlawful acts; (iii) crisis management process and business continuity; (iv) processes and guidelines of the governmental and institutional relations; (v) corporate communication process; (vi) brand management process; (vii) ombudsman offices initiatives and commitment to customer satisfaction; and (viii) ethics guidelines and prevention of corruption.

Itaú Unibanco has introduced a corporate policy in order to prevent its involvement in illegal acts and to protect its reputation and image towards employees, clients, strategic partners, suppliers, service providers, regulators and society, through a governance structure based on transparency, strict compliance with rules and regulations and cooperation with police and judicial authorities. It is also continuously aligned It also seeks continuous alignment with local and international best practices for preventing and fighting against illegal acts, through investing and training employees. In compliance with the guidelines of this corporate policy, Itaú Unibanco established a program to prevent and fight against illegal acts based on the following pillars: · Client Identification Process; · Know Your Client (KYC) Process; · Know Your Partner (KYP) Process; · Know Your Supplier (KYS) Process; · Know Your Employee (KYE) Process; · Assessment of New Products and Services; · Monitoring of Transactions; · Reporting Suspicious Transactions to the Regulatory Bodies; and · Training and Awareness Raising. This program applies to the entire institution, including subsidiaries and affiliates in Brazil and abroad. Governance on preventing and combating unlawful acts is carried out by the Board of Directors, Audit Committee, Operational Risk Committee and Anti-Money Laundering Committees. The document that presents the guidelines established in the program to prevent and combat unlawful acts may be seen on the www.itau.com.br/investor-relations, section Itaú Unibanco, under Corporate Governance, Rules and Policies. In addition, Itaú Unibanco is committed to protecting corporate information and ensuring client privacy in any transactions. To this end, it has a Corporate Information Security Policy and has a monitoring process and a control structure that covers technology, business areas and international units, adhering to principal regulatory bodies and external audits, and best market practices and certifications. Additionally, a Security Operation Center (SOC) that works 24/7 contributes to the cyber security of Itaú Unibanco’s electronic channels and IT infrastructure, the monitoring of operations and thus minimization of the risk of a security incident. 56 Itaú Unibanco Risk and Capital Management – Pillar 3 Since the reputational risk directly or indirectly permeates all operations and processes of the institution, Itaú Unibanco’s governance is structured in a way to ensure that potential reputational risks are identified, analyzed and managed still in the initial phases of its operations and analysis of new products.
