Risk and Capital Management – Pillar 3

1 Risk Management

To assume 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 Itau 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 Itau 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 February 23, 2017, BACEN published Resolution CMN 4,557, 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. The new standard entered into force on August 21, 2017, and revokes CMN Resolutions 3,380, 3,464, 3,721, 3,988, and 4,090, which established the implementation of operational, market, credit, capital and liquidity risks management, respectively.

Itaú Unibanco complies with the best risk and capital management practices set forth in CMN Resolution 4557; accordingly, there is no significant impact arising from its adoption.

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.

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 its risk culture. Itau Unibanco’s Risk Culture is based on four basic principles: conscious risk taking, discussion about and actions on the institution’s risks, and each and everyone’s responsibility for risk management.

These principles connect Itau Unibanco’s guidelines and help employees to consciously understand, identify, measure, manage and mitigate risks.

In addition to the bank’s policies, procedures and processes, the risk culture strengthens the employees’ individual and collective responsibility for managing the risks connected to their individual activities, respecting business management with ethics.

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 Itau 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 Control and Management Area (ACGRF).

Furthermore, to support this structure, ACGRF is structured with specialized departments. The objective is provide independent and centralized management of the institution’s risks and capital, and ensuring the accordance with 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 “Financial Information”.

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 Itau 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 Itau Unibanco’s exposure, to ensure correct and speedy 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.

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, with FEBRABAN’s normative SARB 017/2016 and with the reporting to the Board of Directors, is responsible for setting out the guidelines on models of compensation to employees and the policy on compensation of management members of the Itaú Unibanco companies.

The practices of compensation takes 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 excess risks and inadequacies.

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 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, under Corporate Governance, Regulations and Policies, “Public Access Report – Capital Management”.

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 3,988, BACEN Circular 3,547 and BACEN Circular Letter 3,774.

The result of the last ICAAP – dated as of December 2016 – showed that, in addition to having enough capital to face all material risks, Itaú Unibanco has a significant cushion, 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 the institution'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 severe 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.

2.4 Recovery Plan

In response to the latest international crises, the Central Bank of Brazil issued Resolution No. 4.502, dated June 30, 2016, requiring a recovery plan to be drawn up by systemically important financial institutions (financial institutions with a total exposure of more than 10% of GDP). The purpose of this plan is to reestablish adequate levels of capital and liquidity, in excess of the minimum regulatory levels, through appropriate strategies in the event of severe systemic or idiosyncratic shocks. Accordingly, an institution would be able to preserve its financial feasibility and continuity without jeopardizing the operation of the National Financial System, and minimizing the need to resort to bailout.

The first version of the Recovery Plan was delivered to the Central Bank of Brazil by Itaú Unibanco in December 2017, after approval by the Board of Directors. The plan covers the whole conglomerate and the overseas subsidiaries. The document will be reviewed annually, so as to ensure that the strategies remain up to date and feasible in the event of organizational, competitive or systemic changes.

To this end, Itaú Unibanco’s recovery plan describes the institution’s critical functions and essential services; and it provides for monthly monitoring, using a set of indicators, of potential risks to solvency and liquidity, and reporting by committees to senior management; and it defines the severe stress scenarios of a systemic and idiosyncratic nature that threaten the institution’s ability to simulate strategies for the recovery of capital and liquidity, their financial impact, the risks of putting it into effect, and potential mitigators. It also establishes a transparent communications plan for the use of all stakeholders.

This comprehensive exercise 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 investors, the financial system or the other participants in the markets where it operates.

2.5 Capital Requirements in Place and in Progress

Itaú Unibanco’s minimum capital requirements follow the set of resolutions⁽²⁾ and circulars disclosed by BACEN that implemented, in Brazil, the global capital requirement standards known as Basel III. These are expressed as ratios of the capital available – stated by the Total Capital, composed by the Tier I Capital (which comprises the Common Equity and Additional Tier I Capital) and Tier II Capital – and the risk-weighted assets (RWA).

The Total Capital, Tier I Capital and Common Equity Tier I Capital ratios are calculated on a consolidated basis, applied to institutions included in Prudential Conglomerate⁽³⁾, 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 rewards.

For purposes of calculating these minimum capital requirements, the total RWA is determined as the sum of the risk-weighted asset amounts for credit, market, and operational risks. Itaú Unibanco uses standardized approaches to calculate credit and operational risk-weighted asset amounts.

From September 1st, 2016, BACEN has authorized Itaú Unibanco to use internal market risk models to determine the total amount of regulatory capital (RWA_MINT), replacing the portion RWA_MPAD, as set out in BACEN Circular 3,646.

The standardized approach continues to be used for external units. Accordingly, use of the internal models does not apply to the following units: Argentina, Chile, Itaú BBA International, Itaú BBA Colombia, Paraguay and Uruguay.

Credit, market and operational risks approaches are treated as described in section “2.6 Risk-Weighted Assets (RWA)”.

From January 1st, 2017 to December 31st, 2017, the minimum Total Capital ratio required is 9.25%, and following the schedule for a gradual reduction, it will be 8% on January 1st, 2019.

Beyond the minimum requirement, the BACEN rules call for Additional Common Equity Tier I Capital (ACP), corresponding to the sum of the components ACP_Conservation, ACP_{Countercyclical} and ACP_Systemic, which, in conjunction with the requirements mentioned, increase capital requirement over time. The amount of each component and the minimum regulatory requirements, as provided for in CMN Resolution 4,193, are described in the table below.

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.

The table below presents the schedule of implementation of Basel III rules in Brazil, as defined by BACEN. The information correspond to the percentages of Itaú Unibanco’s risk weighted assets.

Basel III - Implementation Schedule	From January 1st
	2015			2016			2017			2018			2019
Common Equity Tier I		4.5	%		4.5	%		4.5	%		4.5	%		4.5	%
Tier I		6.0	%		6.0	%		6.0	%		6.0	%		6.0	%
Total Capital		11	%		9.875	%		9.25	%		8.625	%		8.0	%
Additional Common Equity Tier I (ACP)		0.0	%		0.625	%		1.50	%		2.375	%		3.5	%
conservation		0	%		0.625	%		1.25	%		1.875	%		2.5	%
countercyclical (1)		0	%		0	%		0	%		0	%		0	%
systemic		0	%		0	%		0.25	%		0.5	%		1.0	%
Common Equity Tier I + ACP		4.5	%		5.125	%		6.0	%		6.875	%		8.0	%
Total Capital + ACP		11.0	%		10.5	%		10.75	%		11.0	%		11.5	%
Prudential adjustments deductions		40	%		60	%		80	%		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), and currently is set to zero. Should the requirement increase, the new percentage takes effect twelve months after the announcement.

In addition to the minimum capital requirements, BACEN Circular 3,748 has been in force since the fourth quarter of 2015. It incorporates the Leverage Ratio in the Basel III framework in Brazil. More details are given in section “2.10 Leverage Ratio” in this report.

Also, in March 2015, Circular BACEN 3,751 came into force. It provides for the calculation of relevant indicators to identify Global Systemically Important Banks (G-SIBs) among financial institutions in Brazil. Following the Basel methodology for identifying G-SIBs, Itaú Unibanco’s score was 39 at 2016. A institution is considered G-SIB whether its score reaches at least 130.

⁽²⁾ The standards that implemented the Basel III rules in Brazil were disclosed on March 1, 2013 through Resolutions No. 4,192 to No. 4,195 of the National Monetary Council (CMN) (Resolution No. 4,195 was revoked by Resolution No. 4,280), together with 15 Circulars published by BACEN on March 4, 2013, as amended.

⁽³⁾ Further details of Prudential Conglomerate can be found in BACEN Circular No. 3,701, CMN Resolution No. 4,280 or in the link: http://www.bcb.gov.br/?BRPRUDENTIALFINREG.

Information on the values of the G-SIBs indicators can been found at www.itau.com.br/investor-relations, section “Corporate Governance”, “Global Systemically Important Banks”.

The compliance of BACEN with the standards recommended by the Basel Committee was assessed at the end of 2013, under the Regulatory Consistency Assessment Programme (RCAP)⁽⁴⁾. The rules effective in Brazil were considered compliant pursuant to the Bank for International Settlements (BIS), Brazil is a compliant jurisdiction i.e., the capital standards established in Brazil are also consistent with the internationally accepted minimum requirements. The pointed out discrepancies were considered immaterial.

Minimum capital requirement for Insurance

In July 2015, the National Council of Private Insurance (CNSP) issued CNSP Resolution 321 and subsequent amendments, which, among other things, deals with the minimum capital requirements for underwriting, credit, operating and market risks for insurers, open private pension entities, premium bonds companies and reinsurers.

2.6 Capital Composition

The Total Capital, used to monitor compliance with the operational limits imposed by BACEN, 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 table below presents the composition of the referential equity and its components (Common Equity Tier I, Additional Tier I Capital and Tier II Capital), taking into consideration their respective prudential adjustments, as required by current regulations.

During the year 2017, Itaú Unibanco bought back R$ 3,089 million of its own shares. These shares are shown as “Treasury Shares”, which showed a balance of R$ (2,743) million as of December 31, 2017. Treasury shares reduce our shareholders’ equity, resulting in a decrease in the capital base.

In this period, the amount of dividends and Interest on capital paid / provided for, which affects Itaú Unibanco’s capital base, was R$ 10,582 million. Dividends are deducted from the institution’s shareholders’ equity, thus reducing its capital base. The interest on capital that is booked directly to income as an expense reduces the institution’s net income, reducing, consequently, the capital base.

More details about Total Capital are given in Appendix I (“Breakdown of the Total Capital and Information on its Adequacy) in this report.

⁽²⁾ According to current legislation, the accounting balance of instruments eligible for Tier II Capital as of December 2012 was used for the calculation of total capital as of December, 2017.

On December 12, 2017, Itaú Unibanco issued perpetual subordinated notes/Additional Tier I (AT1), in the total amount of R$ 4,135 billion. The Notes were issued at the fixed rate of 6.125% to be validated until the 5th anniversary of the issue date. As from this date, inclusive, the interest rate will be recalculated every 5 years based on the interest rate of securities issued by the Treasury of the United States of America for the same period. The offer price of the Notes was 100%, which will result to investors in a return of 6.125% until the 5th anniversary of the Issue date. The Issue is neither subject to registration rules with the Securities Exchange Commission - SEC, in compliance with the Federal North-American law “Securities Act of 1933”, as amended (Securities Act), nor to registration with CVM, in Brazil, in compliance with applicable law and regulations. Notes are subject to BACEN’s approval for composition of Supplementary Capital of its Referential Equity, thus increased by approximately 0.6 p.p. the Company’s Tier I capitalization ratio, in compliance with CMN Resolution 4.192/13.

2.7 Risk-Weighted Asset (RWA)

According to CMN Resolution 4,193 and subsequent amendments, for assessing the minimum capital requirements, the RWA must be calculated by adding the following portions:

RWA = RWA_CPAD + RWA_MINT+ RWA_OPAD

· RWA_CPAD = portion related to exposures to credit risk, calculated using standardized approach;

· RWA_MINT = portion related to the market risk capital requirement, made up of the maximum between the internal model and 80% of the standardized model, and regulated by BACEN Circulars 3,646 and 3,674;

· RWA_OPAD = portion related to the operational risk capital requirement, calculated using standardized approach.

2.9 Capital Adequacy

Itaú Unibanco, through ICAAP process, assesses the adequacy of its capital to face the incurred risks, composed by regulatory capital for credit, market and operational risks and by the necessary capital to face other risks.

In order to ensure the soundness of Itaú Unibanco and the availability of capital to support business growth, Itaú Unibanco maintains capital levels above the minimum requirements, according to the Common Equity Tier I, Additional Tier I Capital, and Tier II minimum ratios.

On December 31, 2017, the Total Capital (PR) reached R$ 142,252million, R$ 122,453 million of Tier I and R$ 19,799 million of Tier II.

Composition of Referential Equity (PR)					R$ million

Referential equity calculated for covering the interest rate risk of trades of the banking book (RBAN)		2,470		2,462		2,264

The Total Capital Ratio reached 18.8% in December 31, 2017, decreasing 70 bps relatively to September 30, 2017, mainly due to the increase of Risk Weighted Assets, including the consolidation of Citibank's Brazilian retail business.

Besides, Itaú Unibanco has an R$ 72,257 million capital excess in relation to its required Total Capital, higher than the Additional Common Equity Tier I requirement of R$ 11,351 million, largely covered by total capital available.

The Fixed Assets Ratio (“Índice de Imobilização”) indicates the level of adjusted Total Capital committed to adjusted permanent assets. Itaú Unibanco is within the maximum limit of 50% of the adjusted Total Capital, as established by BACEN.

The Total Capital and Fixed Assets ratios are presented in the table below.

2.10 Leverage Ratio

The Leverage Ratio is defined as the ratio between Tier I Capital and Total Exposure, calculated according to BACEN Circular 3,748. The ratio is intended to be a simple measure of non-risk-sensitive leverage, and so it does not take into account risk weighs or risk mitigation. As required by BACEN Circular Letter 3,706, Itaú Unibanco has since October 2015 been reporting the Leverage Ratio to BACEN monthly, however the minimum Leverage Ratio became mandatory since January, 2018, according to Basel recommendations, and is defined based on the observations during a period from its implementation in 2011 until 2017.

The following information is based on the methodology and standard format introduced by BACEN Circular 3,748. As of December 31, 2017, Itaú Unibanco’s Leverage Ratio reached 8.9%.

In the fourth quarter of 2017, there were no significant amendments to policies related to investments in other entities.

Itaú Unibanco holds corporate interests mainly for strategic reasons and to obtain capital gains.

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, in the section “Corporate Governance, Rules and Policies”.

Allowance for Loan Losses

In order to be hedged against losses arising from loan operations, Itaú Unibanco takes into consideration all the aspects that determine the client’s credit risk to establish the provision level that is appropriate to the risk incurred in each operation. For each operation, the assessment and the client or economic group rating, the operation rating, and the possible existence of past due amounts are taken into account and the volume of the regulatory provision is determined.

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.

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 encompass 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, Itau 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.

Acquisitions, Sale or Transfer of Financial Assets

The acquisition of financial assets follows the same policies and the same credit governance established for the portfolios originated at Itaú Unibanco. Financial asset acquisitions aim at increasing loan portfolio diversification and meeting the clients’ demands for liquidity. The purpose of the sale and transfer of financial assets is to meet investor demand for credit assets or work as a portfolio credit risk management instrument.

Credit assignments (transfers of receivables) carried out through December 2011 were recorded in accordance with current regulation together with income recognition at the time of the assignment, regardless of the risks and benefits being retained or not.

Since January 2012, as determined by CMN Resolution 3,533 and supplementary regulation, accounting records take into consideration the retention or non-retention of risks and benefits on sale or transfers of financial assets.

Itaú Unibanco’s portfolio includes securities arising from securitization processes. The portfolio is made up of Securitized Real Estate Loans (CRI), quotas of Credit Rights Investment Funds (FIDC) and Agribusiness Receivables Certificate (CRA) and debentures with securitization characteristics (issues whose flow of receipts is dependent on the performance of the underlying receivables).

Exposure to securitization of FIDC, in the consolidated accounts, includes only fund units not consolidated in the Prudential Conglomerate. According to BACEN Circular 3,701, FIDC units when the institution has control or retains risks and benefits must be consolidated in the Prudential Conglomerate. Itaú Unibanco classifies securities arising from securitization processes based on the governance of products determined, and the credit is approved at the proper authority levels.

Itaú Unibanco follows risk retention guidelines of CMN Resolution 3,533.

The balances of these operations are presented below.

It should be noted that the portion of RWA_CPAD attributable to securitization exposure did not exceed 5% of the total on December 31, 2017.

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.

Risk and Capital Management – Pillar 3

Credit Derivatives

Itaú Unibanco buys and sells credit protection mainly related to securities of the Brazilian government and securities of Brazilian listed companies in order to meet the needs of its customers. When Itaú Unibanco sells contracts for credit protection, the exposure for a given reference entity may be partially or totally offset by a credit protection purchase contract of another counterparty for the same reference entity or similar entity.

CDS (credit default swap) is credit derivative in which, upon a default related to the reference entity, the protection buyer is entitled to receive, from the protection seller, the amount equivalent to the difference between the face value of the CDS contract and the fair value of the liability on the date the contract was settled, also known as the recovered amount. The protection buyer does not need to hold the debt instrument of the reference entity for it to receive the amounts due pursuant to the CDS contract terms when a credit event occurs.

TRS (total return swap) is a transaction in which a party swaps the total return of an asset or of a basket of assets for regular cash flows, usually interest and a guarantee against capital loss. In a TRS contract, the parties do not transfer the ownership of the assets.

The maximum potential loss that may be incurred with credit derivatives is the notional amount of the derivative. Itaú Unibanco believes that, based on its historical experience, the maximum potential loss does not represent the expected loss, because, when a loss event occurs, the amount of maximum potential loss should be reduced from the notional amount by the recoverable amount.

The credit derivatives sold are not covered by guarantees, and during the fourth quarter of 2017, Itaú Unibanco has not incurred any loss related to credit derivative contracts.

The table below shows the nominal value of purchased credit derivatives that are identical to those for which Itaú Unibanco acts as seller of protection underlying values.

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 7g 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;

37

Itaú Unibanco

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, in the route: Corporate Governance, Rules and Policies, Public Access Report - Market Risk.

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.

Sensibility of Banking Position (1)								R$ million
	Exposures	12/31/2017
Risk factors	Risk of variation in:	Scenario I			Scenario II			Scenario III
Interest Rate	Fixed Income Interest Rates in reais		(8	)		(1,467	)		(2,876	)

Price Index Linked	Interest of Inflation coupon		(3	)		(207	)		(391	)
TR	TR Linked Interest Rates		-			(121	)		(308	)

⁽¹⁾ Amounts net of tax effects.

In order to measure these sensitivities, the following scenarios are used:

·     Scenario I: Shocks of 1 base point in interest fixed rates, currency coupon, inflation, interest rate indexes, and 1 percentage point in the prices of currencies and shares;

·     Scenario II: Shocks of 25% in interest fixed rates, currency coupon, inflation, interest rate indexes, and in the prices of currencies and shares, both for growth and fall, considering the largest resulting losses per risk factor;

·      Scenario III: Shocks of 50% in interest fixed rates, currency coupon, inflation, interest rate indexes, and in the prices of currencies and shares, both for growth and fall, considering the largest resulting losses per risk factor.

VaR – Consolidated Itaú Unibanco

Consolidated VaR of Itaú Unibanco is calculated by Historical Simulation, i.e., the expected distribution for profit and loss (P&L’s - Profit and loss statement) of a portfolio over a time horizon that can be estimated based on the historical behavior of returns of market risk factors of this portfolio. VaR is calculated at a confidence level of 99%, historical period of 4 years (1000 business days) and a holding period of one day. In addition, in a conservative approach, VaR is calculated daily, being or not volatility-weighted, and the final VaR is the most restrictive value between both methodologies.

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 did not show failures in relation to 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.

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 under Corporate Governance, Rules and Policies, Public Access Report – Operational Risk.

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 shown below:

· Disaster Recovery Plan: focused on the recovery of its primary data center, ensuring the continuity of the processing of critical systems within minimum pre-established periods;

· Workplace Contingency Plan: employees responsible for carrying out critical business functions have alternative facilities to perform their activities in the event the buildings in which they usually work become unavailable.

· Emergency Plan: procedures aimed at minimizing the effects of emergency situations that may impact Itaú Unibanco’s facilities, with a preventive focus;

· Processes Contingency Plan: alternatives (Plan B) to carry out the critical processes identified in the business areas.

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, but 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 understand the institution:

– Business Impact Analysis (BIA): evaluates the criticality and resumption requirement of the processes that support the delivery of products and services. Through this analysis the businesses’ resumption priorities are defined.

– Threats and Vulnerabilities Analysis (AVA): identification of threats to the locations where Itaú Unibanco buildings are located.

In addition, the institution has a Corporate-wide 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.

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.

8 Liquidity Risk

8.1 Framework and Treatment

Liquidity risk is defined as the likelihood of the institution not being able to effectively honor its expected and unexpected obligations, current and future, including those from guarantees commitment, without affecting its daily operations or incurring significant losses.

Liquidity risk control is carried out by an area that is independent of the business areas, and which is responsible for defining the composition of the reserve, estimating cash flow and exposure to liquidity risk over different time horizons, and monitoring the minimum limits for absorbing losses in stress scenarios in the countries where Itaú Unibanco operates. All activities are subject to assessment by the independent validation, internal controls and audit departments.

Additionally, and pursuant to the requirements of CMN Resolutions 4,090 and BACEN Circular 3,749, Itaú Unibanco makes monthly delivery of its Liquidity Risk Statements (DLR) to BACEN and the following items are regularly prepared and submitted to the senior management for monitoring and decision support:

· Different scenarios for liquidity projections;

· Contingency plans for crisis situations;

· Reports and charts to enable monitoring risk positions;

· Assessment of funding costs and alternatives;

· Tracking the sort of funding sources through a continuous control of funding sources considering counterparty type, maturity and other aspects.

The document that details the liquidity risk control institutional policy is on the Investor Relations website www.itau.com.br/investor-relations, in the route: Corporate Governance, Rules and Policies, Public Access Report - Liquidity Risk.

8.2 Liquidity Coverage Ratio (LCR)

The Liquidity Coverage Ratio (LCR), which is calculated as required by BACEN, in line with the Basel international standard, is defined as follows:

LCR =	HQLA
	Outflowse – Min (Inflowss; 75% x Outflowss)

·   HQLA High Quality Liquid Assets = correspond to inventories, in some cases weighted by a discount factor, of assets that remain liquid in the market even in periods of stress, that can easily be converted into cash and that are classified as low risk;

·   Outflows_s = total potential cash outflows for a 30-day horizon, calculated for a standard stress scenario as defined by BACEN Circular 3,749;

·   Inflows_s = total potential cash inflows for a 30-day horizon, calculated for a standard stress scenario as defined by BACEN Circular 3,749.

According to the instructions in BACEN Circular 3,775, banks with total assets exceeding R$100 billion have since October 2015 been required to submit a monthly Prudential Conglomerate LCR to BACEN. This indicator is subject to a progressive minimum regulatory requirement, as presented below.

Itaú Unibanco

Risk and Capital Management – Pillar 3

Itaú Unibanco has a structured flow for addressing rules, covering the stages of recognition, distribution, monitoring and compliance, and all of these processes are established in internal policies.The flow for handling regulatory risk involves various areas of the institution, and consists of: (i) structure of lines of defense; (ii) monitoring of draft legislation, public notices and public hearings; (iii) monitoring of new rules and definition of action plans; (iv) relationship with regulators and professional organizations; (v) monitoring of action plans; (vi) control over compliance with legal decisions and TAC (conduct adjustment agreements), executed in public civil actions. In addition, the institution’s risks are classified and prioritized according to the Itaú Unibanco internal control methodology.

Model Risk

This risk may materialize due to the use in different situations from those modeled. The best practices that mark the model risk control at the institution include: (i) certification of the quality of the database used; (ii) application of a check-list of essential steps to be taken during the development; (iii) conservatism in judgmental models (iv) use of external benchmarks; (v) approval of results generated in implementation; (vi) independent technical validation; (vii) validation of use; (viii) assessments of the impact in the use; (ix) monitoring of performance; and (x) monitoring of the distribution of the explanatory variables and final score.

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 ACGRF 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.

49

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 the use of Itaú Unibanco in 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 (vii) ethics guidelines and prevention of corruption.

Financial institutions play a key role in preventing and fighting illegal acts, in particular money laundering, terrorist financing and fraud, for which the challenge is to identify and suppress increasingly sophisticated operations that seek to conceal the origin, ownership and movement of goods and money derived from illegal activities. Itaú Unibanco has introduced a corporate policy in order to prevent its involvement in illegal acts and to protect its reputation and image towards stakeholders, 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 with local and international best practices for preventing and fighting against illegal acts, through investing and continuously 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 and corporate bodies. 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 website in the section Corporate Governance, Regulations and Policies, corporate policy to prevent and fight against unlawful acts.

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.
