Risk And Capital Management |
Risk and Capital Management | Note 32 - Risk and Capital Management a) Corporate Governance ITAÚ UNIBANCO HOLDING invests in robust risk management processes and capital management that are the basis for its strategic decisions to ensure business sustainability and maximize shareholder value creation. These processes are aligned with the guidelines of the Board of Directors and Executive which, through collegiate bodies, define the global objectives expressed as targets and limits for the business units that manage risk. Control and capital management units, in turn, support ITAÚ UNIBANCO HOLDING’s management by monitoring and analyzing risk and capital. The Board of Directors is the main body responsible for establishing guidelines, policies and approval levels for risk and capital management. The Capital and Risk Management Committee (CGRC), in turn, is responsible for supporting the Board of Directors in managing capital and risk. At the executive level, collegiate bodies, presided over by the Chief Executive Officer (CEO) of ITAÚ UNIBANCO HOLDING, are responsible for capital and risk management, and their decisions are monitored by the CGRC. Additionally, ITAÚ UNIBANCO HOLDING has collegiate bodies with capital and risk management responsibilities delegated to them, under the responsibility of CRO (Chief Risk Officer). To support this structure, the Risk Department has departments to ensure, on an independent and centralized basis, that the institution’s risks and capital are managed in compliance with the defined policies and procedures. ITAÚ UNIBANCO HOLDING's management model is made up of:
• |  | 1st line of defense: business areas, which have primary responsibility for managing the risk they originate.
• |  | 2nd line of defense: risk area, which ensures that risks are managed and are supported by risk management principles (risk appetite, policies, procedures and dissemination of the risk culture in the business).
• |  | 3rd line of defense: internal audit, which is linked to the Board of Directors and makes an independent assessment of the activities developed by the other areas.
b) Risk Management Risk Appetite The risk appetite of ITAÚ UNIBANCO HOLDING is based on the Board of Director’s statement: “We are a universal bank, operating mainly in Latin America. Supported by our risk culture, we insist on with strict ethical standards and regulatory compliance, seeking high and increasing returns, with low volatility, through lasting relationships with our customers, accurate risk pricing, widespread funding and proper use of capital.” Based on this statement, six dimensions have been defined, each dimension consists of a set of metrics associated with the main risks involved, combining supplementary measurement methods, to give a comprehensive vision of our exposure. The Board of Directors is responsible for approving guidelines and limits for risk appetite, with the support of CGRC and the CRO. The limits for risk appetite are monitored regularly and reported to risk committees and to the Board of Directors, which will oversee the preventive measures to be taken to ensure that exposure is aligned with the strategies of ITAÚ UNIBANCO HOLDING. Foremost among processes for proper risk and capital management are the Risk Appetite Statement (RAS) and the implementation of a continuous, integrated risk management structure, the stress test program, the establishment of a Risk Committee, and the nomination at BACEN of a Chief Risk Officer (CRO), with roles and responsibilities assigned, and requirements for independence. The six dimensions of risk appetite are:
• |  | Capitalization: establishes that ITAÚ UNIBANCO HOLDING must have capital sufficient to face any serious recession period or a stress event without the need to adjust its capital structure under unfavorable circumstances. It is monitored by tracking ITAÚ UNIBANCO HOLDING’s capital ratios, both in normal and stress scenarios, and of the ratings of the institution's debt issues.
• |  | Liquidity: establishes that the liquidity of ITAÚ UNIBANCO HOLDING must withstand long periods of stress. It is monitored by tracking liquidity indicators.
• |  | Composition of results: defines that business will be focused primarily on Latin America, where ITAÚ UNIBANCO HOLDING has a diversified base of customers and products, with low appetite for income volatility or for high risk. This dimension comprises aspects related to business, profitability, market risk and credit risk. By adopting exposure concentration limits, such as industry sectors, counterparty quality, countries and geographical regions and risk factors, these monitored metrics are intended to ensure well-adjusted portfolios, low income volatility and business sustainability.
• |  | Operational risk: focuses on the control of operating risk events that may adversely impact business and operating strategy, and involves monitoring the main operational risk events and losses incurred.
• |  | Reputation: addresses risks that may impact the institution’s brand value and reputation with customers, employees, regulatory bodies, investors and the general public. The risk monitoring in this dimension is carried in addition to monitoring the institution’s conduct.
• |  | Clients: addresses risks that could compromise client’s satisfaction and experience, being monitored by follow-up of customer’s satisfaction and dissatisfaction, media exposure, direct impacts on clients (technology) and suitability indicators.
Risk appetite, risk management and guidelines for employees of ITAÚ UNIBANCO HOLDING for routine decision-making purposes are based on:
• |  | Sustainability and customer satisfaction: ITAÚ UNIBANCO HOLDING's vision is to be the leading bank in sustainable performance and customer satisfaction and, accordingly, it is committed to creating shared value for staff, customers, stockholders and society, ensuring the continuity of the business. ITAÚ UNIBANCO HOLDING is committed to doing business that is good both for the customer and the institution itself.
• |  | Risk culture: ITAÚ UNIBANCO HOLDING’s risk culture goes beyond policies, procedures or processes, reinforcing the individual and collective responsibility of all employees so that they will do the right thing at the right time and in the proper manner, respecting the ethical way of doing business.
• |  | Risk pricing: ITAÚ UNIBANCO HOLDING ’s operates and assumes risks in businesses that it knows and understands, avoids the ones that are unknown or that do not provide competitive advantages, and carefully assesses risk-return ratios.
• |  | Diversification: ITAÚ UNIBANCO HOLDING has little appetite for volatility in earnings, and it therefore operates with a diverse base of customers, products and business, seeking to diversify risks and giving priority to lower risk business.
• |  | Operational excellence: It is the wish of ITAÚ UNIBANCO HOLDING to be an agile bank, with a robust and stable infrastructure enabling us to offer top quality services.
• |  | Ethics and respect for regulations: for ITAÚ UNIBANCO HOLDING, ethics is non-negotiable, and it therefore promotes an institutional environment of integrity, encouraging staff to cultivate ethics in relationships and business and to respect the rules, thus caring for the institution’s reputation.
ITAÚ UNIBANCO HOLDING has various ways of disseminating risk culture, based on four principles: conscious risk-taking, discussion of the risks the institution faces, the corresponding action taken, and the responsibility of everyone for managing risk. These principles serve as a basis for ITAÚ UNIBANCO HOLDING guidelines, helping employees to conscientiously understand, identify, measure, manage and mitigate risks. I - Credit risk The possibility of losses arising from failure by a borrower, issuer or counterparty to meet their financial obligations, the impairment of a loan due to downgrading of the risk rating of the borrower, the issuer or the counterparty, a decrease in earnings or remuneration, advantages conceded on renegotiation or the costs of recovery. There is a credit risk control and management structure, centralized and independent from the business units, that provides for operating limits and risk mitigation mechanisms, and also establishes processes and tools to measure, monitor and control the credit risk inherent in all products, portfolio concentrations and impacts of potential changes in the economic environment. The credit policy of ITAÚ UNIBANCO HOLDING is based on internal criteria such as: classification of customers, portfolio performance and changes, default levels, rate of return and economic capital allocated, among others, and also take into account external factors such as interest rates, market default indicators, inflation, changes in consumption, and so on. For personal customers and small and middle-market companies, credit rating is based on statistical application models (at the early stages of the relationship with a customer) and behavior score (used for customers with which ITAÚ UNIBANCO HOLDING already has a relationship). For large companies, the rating is based on information such as economic and financial condition of the counterparty, their cash-generating capability, the economic group to which they belong, and the current and prospective situation of the economic sector in which they operate, in accordance with the guidelines of the Sustainability and Social and Environmental Responsibility Policy (PRSA) and specific manuals and procedures of ITAÚ UNIBANCO HOLDING. Credit proposals are analyzed on a case by case basis, through an approval-level mechanism. ITAÚ UNIBANCO HOLDING strictly controls the credit exposure of customers and counterparties, taking action to address situations in which the current exposure exceeds what is desirable. For this purpose, measures provided for in loan agreements are available, such as accelerated maturity or a requirement for additional collateral. I.I - Collateral and policies for mitigating credit risk ITAÚ UNIBANCO HOLDING uses guarantees to increase its capacity for recovery in operations exposed to credit risk. The guarantees may be personal, secured, legal structures with mitigating power and offset agreements. For collateral to be considered instruments that mitigate credit risk, they must comply with the requirements and standards that regulate them, both internal and external ones, and they must be legally valid (effective), enforceable, and assessed on a regular basis. ITAÚ UNIBANCO HOLDING also uses credit derivatives, to mitigate credit risk of its portfolios of loans and securities. These instruments are priced based on models that use the fair value of market inputs, such as credit spreads, recovery rates, correlations and interest rates. I.II - Policy for Provisioning and Economic Scenarios Both the credit risk and the finance areas are responsible for defining the methods used to measure expected loan losses and for periodically assessing changes in the provision amounts. These areas monitor the trends observed in provisions for expected credit losses by segment, in addition to establishing an initial understanding of the variables that may trigger changes in the allowance for loan losses, the probability of default (PD) or the loss given default (LGD). Once the trends have been identified and an initial assessment of the variables has been made at the corporate level, the business areas are responsible for further analyzing these trends in more detail and for each segment, in order to understand the underlying reasons for the trends and to decide whether changes are required in credit policies. Provisions for expected losses take into account the expected risk linked to contracts with similar characteristics and in anticipation of signs of deterioration, over a loss horizon suitable for the remaining period of the contract to maturity. For contracts of products with no determined termination date, average results of deterioration and default are used to determine the loss horizon. Additionally, information on economic scenarios and public data with internal projections are used to determine and adjust the expected credit loss in line with expected macroeconomic realities.
Sensitivity analysis |  |  |  |  |  |  |  |  |
ITAÚ UNIBANCO HOLDING prepares studies on the impact of estimates in the calculation of expected credit loss. The expected loss models use three different scenarios: Optimistic, Base and Pessimistic. In Brazil, where operations are substantially carried out, these scenarios are combined by weighting their probabilities: 15%, 50% and 35%, respectively, which are updated so as to reflect the new economic conditions. For loan portfolios originated in other countries, the scenarios are weighted by different probabilities, considering regional economic aspects and conditions.
The table below shows the amount of financial assets at amortized cost and at fair value through other comprehensive income, expected loss and the impacts on the calculation of expected credit loss in the adoption of 100% of each scenario:

I.III - Classification of Stages of Credit Impairment ITAÚ UNIBANCO HOLDING uses customers’ internal information, statistic models, days of default and quantitative analysis in order to determine the credit status of portfolio agreements. Rules for changing stages take into account:
• |  | Stage 1 to stage 2: delay or evaluation of probability of default (PD) triggers.
For Retail market portfolios, ITAÚ UNIBANCO HOLDING classifies loan agreements which are over 30 days overdue in stage 2, except payroll loans for government agency, for which the figure is 45 days, due to the dynamics of payment for transfer of the product. For agreements with delay less than 30 days, the migration to stage 2 occurs if the financial asset exceeds the allowance for loan losses established by the risk appetite approved by ITAÚ UNIBANCO HOLDING’s Management for each portfolio, whereas the others remain in stage 1. For the Wholesale business portfolio, information on arrears is taken into account when assessing the counterparty rating.
• |  | Stage 3: default parameters are used to identify stage 3: 90 days without payment noted, except for the mortgage loan portfolio, which are considered 180 days; debt restructuring; filing for bankruptcy; loss; and court-supervised recovery. The financial asset, at any stage, can migrate to stage 3 when showing default parameters.
Information on days of delay, used on an absolute basis, is one important factor for the classification of stages, and after a certain credit status has been defined for an agreement, it is classified in one of the three stages of credit deterioration. Based on this classification, rules for measuring expected credit loss in each stage are used, as described in Note 2d IV.

Amounts shown for credit risk exposure are based on gross book value and do not take into account any collateral received or other added credit improvements.
The contractual amounts of financial guarantees and letters of credit cards represent the maximum potential of credit risk in the event that a counterparty does not meet the terms of the agreement. The vast majority of loan commitments (mortgage loans, overdraft accounts and other pre-approved limits) mature without being drawn, since they are renewed monthly and can be cancelled unilaterally.
As a result, the total contractual amount does not represent our real future exposure to credit risk or the liquidity needs arising from such commitments.

3) Properties themselves are pledged as collateral.
4) Any collateral set forth in the credit policy of ITAÚ UNIBANCO HOLDING (chattel mortgage, surety/joint debtor, mortgage and other).
Of total loan and lease operations, R$ 362,705 (R$ 326,862 at 12/31/2021) represented unsecured loans. I.IV.IV - Repossessed assets Assets received from the foreclosure of loans, including real estate, are initially recorded at the lower of: (i) the fair value of the asset less the estimated selling expenses, or (ii) the carrying amount of the loan. Further impairment of assets is recorded as a provision, with a corresponding charge to income. The maintenance costs of these assets are expensed as incurred. The policy for sales of these assets includes periodic auctions that are announced to the market in advance, and provides that the assets cannot be held for more than one year, as stipulated by BACEN. Total assets repossessed in the period were R$ 336 (R$ 258 from 01/01 to 12/31/2021), mainly composed of real estate. II - Market risk The possibility of incurring financial losses from changes in the market value of positions held by a financial institution, including the risks of transactions subject to fluctuations in currency rates, interest rates, share prices, price indexes and commodity prices, as set forth by CMN. Price Indexes are also treated as a risk factor group. Market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and alerts, (iii) application, analysis and testing of stress scenarios, (iv) risk reporting to those responsible within the business areas, in compliance with the governance of ITAÚ UNIBANCO HOLDING, (v) monitoring of actions required to adjust positions and risk levels to make them realistic, and (vi) providing support for the safe launch of new financial products. The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution 4,557, of February 23, 2017, and BCB Resolution No. 111, of July 6, 2021 and later changes. The trading portfolio consists of all transactions involving financial instruments and commodities, including derivatives, which are held for trading. The banking portfolio is basically characterized by transactions for the banking business, and transactions related to the management of the balance sheet of the institution, where there is no intention of sale and time horizons are medium and long term. Market risk management is based on the following metrics:
• |  | Value at risk (VaR): a statistical measure that estimates the expected maximum potential economic loss under normal market conditions, considering a certain time horizon and confidence level.
• |  | Losses in stress scenarios (Stress Test): simulation technique to assess the behavior of assets, liabilities and derivatives of a portfolio when several risk factors are taken to extreme market situations (based on prospective and historical scenarios).
• |  | Stop loss: metrics used to revise positions, should losses accumulated in a fixed period reach a certain level.
• |  | Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at market value (MtM – Mark to Market).
• |  | Stressed VaR: statistical metric derived from the VaR calculation, with the purpose is of simulating higher risk in the trading portfolio, taking returns that can be seen in past scenarios of extreme volatility.
Management of interest rate risk in the Banking Book (IRRBB) is based on the following metrics:
• |  | ΔEVE (Delta Economic Value of Equity): 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 these instruments in a scenario of shock in interest rates.
• |  | ΔNII (Delta Net Interest Income): difference between the result of financial intermediation of instruments subject to IRRBB in a base scenario and the result of financial intermediation of these instruments in a scenario of shock in interest rates.
In addition, sensitivity and loss control measures are also analyzed. They include:
• |  | Mismatching analysis (GAPS): accumulated exposure by risk factor of cash flows expressed at market value, allocated at the maturity dates.
• |  | Sensitivity (DV01- Delta Variation): impact on the fair value of cash flows when a 1 basis point change is applied to current interest rates or on the index rates.
• |  | Sensitivity to Sundry Risk Factors (Greeks): partial derivatives of an option portfolio in relation to the prices of underlying assets, implied volatilities, interest rates and time.
In order to operate within the defined limits, ITAÚ UNIBANCO HOLDING hedges transactions with customers and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, which can be either accounting or economic hedges, both governed by the institutional polices of ITAÚ UNIBANCO HOLDING. The structure of limits and alerts obeys the Board of Directors’ guidelines, and it is reviewed and approved on an annual basis. This structure has specific limits aimed at improving the process of monitoring and understanding risk, and at avoiding concentration. These limits are quantified by assessing the forecast balance sheet results, the size of stockholders’ equity, market liquidity, complexity and volatility, and ITAÚ UNIBANCO HOLDING’s appetite for risk. The consumption of market risk limits is monitored and disclosed daily through exposure and sensitivity maps. The market risk area analyzes and controls the adherence of these exposures to limits and alerts and reports them timely to the Treasury desks and other structures foreseen in the governance. ITAÚ UNIBANCO HOLDING uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in a high-availability access-controlled environment, which has data storage and recovery processes and an infrastructure that ensures business continuity in contingency (disaster recovery) situations. II.I - VaR - Consolidated ITAÚ UNIBANCO HOLDING Is calculated by Historical Simulation, i.e. the expected distribution for profits and losses (P&L) of a portfolio over time can be estimated from past behavior of returns of market risk factors for 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, with and without volatility weighting, and the final VaR is the more restrictive of the values given by the two methods. From 01/01 to 12/31/2022, the average total VaR in Historical Simulation was R$ 678 or 0.4% of total stockholders’ equity (R$ 441 from 01/01 to 12/31/2021 or 0.3% of total stockholders’ equity).

II.I.II - Currency risk The purpose of ITAÚ UNIBANCO HOLDING's management of foreign exchange exposure is to mitigate the effects arising from variation in foreign exchange rates, which may present high-volatility periods. The currency (or foreign exchange) risk arises from positions that are sensitive to oscillations in foreign exchange rates. These positions may be originated by financial instruments that are denominated in a currency other than the functional currency in which the balance sheet is measured or through positions in derivative instruments (for negotiation or hedge). Sensitivity to currency risk is disclosed in the table VaR Total (Historical Simulation) described in item II.I – VaR Consolidated – ITAÚ UNIBANCO HOLDING. II.I.III - Share Price Risk The exposure to share price risk is disclosed in Note 5, related to Financial Assets Through Profit or Loss - Securities, and Note 8, related to Financial Assets at Fair Value Through Other Comprehensive Income - Securities. III - Liquidity risk Defined as the possibility that the institution may be unable to efficiently meet its expected and unexpected obligations, both current and future, including those arising from guarantees issued, without affecting its daily operations and without incurring significant losses. Liquidity risk is controlled by an area independent from the business area and responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different time horizons, and for monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING operates. All activities are subject to verification by independent validation, internal control and audit areas. Liquidity management policies and limits are based on prospective scenarios and senior management’s guidelines. These scenarios are reviewed on a periodic basis, by analyzing the need for cash due to atypical market conditions or strategic decisions by ITAÚ UNIBANCO HOLDING. ITAÚ UNIBANCO HOLDING manages and controls liquidity risk on a daily basis, using procedures approved in superior committees, including the adoption of liquidity minimum limits, sufficient to absorb possible cash losses in stress scenarios, measured with the use of internal and regulatory methods. Additionally the following items for monitoring and supporting decisions are periodically prepared and submitted to senior management:
• |  | Different scenarios projected for changes in liquidity.
• |  | Contingency plans for crisis situations.
• |  | Reports and charts that describe the risk positions.
• |  | Assessment of funding costs and alternative sources of funding.
• |  | Monitoring of changes in funding through a constant control of sources of funding, considering the type of investor, maturities and other factors.
III.I - Primary sources of funding ITAÚ UNIBANCO HOLDING has different sources of funding, of which a significant portion is from the retail segment. Of total customers’ funds, 31.5% or R$ 373.0 billion, is immediately available to customers. However, the historical behavior of the accumulated balance of the two largest items in this group – demand and savings deposits - is relatively consistent with the balances increasing over time and inflows exceeding outflows for monthly average amounts.

IV - Emerging Risks They are those with a potentially material impact on the business in the medium and long terms, but for which there are not enough elements yet for their complete assessment and mitigation due to the number of factors and impacts not yet totally known, such as technological alternatives in replacement of traditional banking services and the demographic transition of clients in contrast to technological innovations. Their causes can be originated by external events and result in the emergence of new risks or in the intensification of risks already monitored by ITAÚ UNIBANCO HOLDING. The identification and monitoring of Emerging Risks are ensured by ITAÚ UNIBANCO HOLDING’s governance, allowing these risks to be incorporated into risk management processes too. V - Social, Environmental and Climate Risks Social, environmental and climate risks are the possibility of losses due to exposure to social, environmental and/or climatic events related to the activities developed by ITAÚ UNIBANCO HOLDING. Social, environmental and climate factors are considered relevant to the business of ITAÚ UNIBANCO HOLDING, since they may affect the creation of shared value in the short, medium and long term. The Policy of Social, Environmental and Climatic Risks (Risks SAC Policy) establishes the guidelines and underlying principles for social, environmental and climatic risk management, addressing the most significant risks for the institution’s operation through specific procedures. Actions to mitigate the Social, Environmental and Climatic Risks are taken based on the mapping of processes, risks and controls, monitoring of new standards related to the theme and recording of occurrence in internal systems. In addition to the identification, the phases of prioritization, response to risk, mitigation, monitoring and reporting of assessed risks supplement the management of these risks at ITAÚ UNIBANCO HOLDING. In the management of Social, Environmental and Climatic Risks, business areas manage the risk in its daily activities, following the Risks SAC Policy guidelines and specific processes, with the support of specialized assessment from dedicated technical teams located in Corporate Compliance, Credit Risk and Modeling, and Institutional Legal teams, that act in an integrated way in the management of all dimensions of the Social, Environmental and Climatic Risks related to the conglomerate’s activities. As an example of specific guidelines for the management of these risks, ITAÚ UNIBANCO HOLDING has specific governance for granting and renewing credit in senior approval levels for clients in certain economic sectors, classified as Sensitive Sectors (Mining, Steel & Metallurgy, Oil & Gas, Textiles & Clothing, Paper & Pulp, Chemicals & Petrochemicals, Meatpacking, Crop Protection and Fertilizers, Wood, Energy, Rural Producers and Real Estate), for which there is an individualized analysis of Social, Environmental and Climate Risks. The institution also has specific procedures for the Institution’s operation (stockholders’ equity, branch infrastructure and technology), suppliers, credit, investments and key controls. Credit Risk and Modeling, Internal Controls and Compliance areas, in turn, support and ensure the governance of the business areas’ activities. The Internal Audit acts in an independent manner, assessing risk management, controls and governance. Governance also counts on the Social, Environmental and Climatic Risks Committee, whose main responsibility is to assess and deliberate about institutional and strategic matters, as well as to resolve on products, operations, and services, among others involving the Social, Environmental and Climatic Risks. Climate Risk includes: (i) physical risks, arising from changes in weather patterns, such as increased rainfall and temperature and extreme weather events, and (ii) transition risks, resulting from changes in the economy as a result of climate actions, such as carbon pricing, climate regulation, market risks and reputational risks. Considering its relevance, climate risk has become one of the main priorities for ITAÚ UNIBANCO HOLDING, which supports the Task Force on Climate-related Financial Disclosures (TCFD) and it is committed to its implementation of its recommendations. With this purpose, ITAÚ UNIBANCO HOLDING is strengthening the governance and strategy related to Climate Risk and developing tools and methodologies to assess and manage these risks. ITAÚ UNIBANCO HOLDING measures the sensitivity of the credit portfolio to climate risks by applying the Climate Risk Sensitivity Assessment Tool, developed by Febraban. The tool combines relevance and proportionality criteria to identify the sectors and clients within the portfolio that are more sensitive to climate risks, considering physical and transition risks. The sectors with the highest probability of suffering financial impacts from climate change, following the TCFD guidelines, are: energy, transport, materials and construction, agriculture, food and forestry products. c) Capital Management Governance ITAÚ UNIBANCO HOLDING is subject to the regulations of BACEN, which determines minimum capital requirements, procedures to obtain information to assess the global systemic importance of banks, fixed asset limits, loan limits and accounting practices, and requires banks to conform to the regulations based on the Basel Accord for capital adequacy. Additionally, CNSP and SUSEP issue regulations on capital requirements that affect our insurance operations and private pension and premium bonds plans. The capital statements were prepared in accordance with BACEN’s regulatory requirements and with internationally accepted minimum requirements according to the Bank for International Settlements (BIS). I - Composition and Capital Adequacy The Board of Directors is the body responsible for approving the institutional capital management policy and guidelines for the capitalization level of ITAÚ UNIBANCO HOLDING. The Board is also responsible for the full approval of the ICAAP (Internal Capital Adequacy Assessment Process) report, the purpose of which is to assess the capital adequacy of ITAÚ UNIBANCO HOLDING. The result of the last ICAAP, which comprises stress tests – which was dated December 2021 – indicated that ITAÚ UNIBANCO HOLDING has, in addition to capital to cover all material risks, a significant capital surplus, thus assuring the solidity of the institution’s equity position. In order to ensure that ITAÚ UNIBANCO HOLDING is sound and has the capital needed to support business growth, the institution maintains PR levels above the minimum level required to face risks, as demonstrated by the Common Equity, Tier I Capital and Basel ratios.
Summary of Composition Of Capital Adequcy |  |
| 12/31/2022 | 12/31/2021
Available capital (amounts) |  |
Common Equity Tier 1 | 147,781 | 130,716

Total capital (PR) | 185,415 | 169,797
Risk-weighted assets (amounts) |  |
Total risk-weighted assets (RWA) | 1,238,582 | 1,153,841
Risk-based capital ratios as a percentage of RWA |  |
Common Equity Tier 1 ratio (%) | 11.9% | 11.3%
Tier 1 ratio (%) | 13.5% | 13.0%
Total capital ratio (%) | 15.0% | 14.7%
Additional CET1 buffer requirements as a percentage of RWA |  |
Capital conservation buffer requirement (%) (1) | 2.50% | 2.00%
Countercyclical buffer requirement (%) | - | -
Bank G-SIB and/or D-SIB additional requirements (%) | 1.0% | 1.0%
Total of bank CET1 specific buffer requirements (%) | 3.50% | 3.00%
1) For purposes of calculating the Conservation capital buffer, BACEN Resolution 4,783 establishes, for defined periods, percentages to be applied to the RWA value with a gradual increase until April/22, when it reaches 2.5%.
At 12/31/2022 the amount of perpetual subordinated debt that makes up Tier I capital is R$ 18,336 (R$ 18,167 at 12/31/2021) and the amount of perpetual subordinated debt that makes up Tier capital II is R$ 18,431 (R$ 19,469 at 12/31/2021). The Basel Ratio reached 15.0% at 12/31/2022, an increase of 0.3 pp compared to 12/31/2021. The mainly effects were the result of the period, partially offset by the increase of Risk-Weighted Assets and the Prudential and Equity Adjustments. Additionally, ITAÚ UNIBANCO HOLDING has a surplus over the required minimum Referential Equity of R$ 86,328 (R$ 77,490 at 12/31/2021), well above the ACP of R$ 43,350 (R$ 34,615 at 12/31/2021), generously covered by available capital. The fixed assets ratio shows the commitment percentage of adjusted Referential Equity with adjusted permanent assets. ITAÚ UNIBANCO HOLDING falls within the maximum limit of 50% of adjusted PR, established by BACEN. At 12/31/2022, fixed assets ratio reached 19.9% (16.9% at 12/31/2021), showing a surplus of R$ 55,748 (R$ 56,280 at 12/31/2021). II - Risk-Weighted Assets (RWA) For calculating minimum capital requirements, RWA must be obtained by taking the sum of the following risk exposures: RWA = RWACPAD + RWAMINT+ RWAOPAD
• |  | RWACPAD = portion related to exposures to credit risk, calculated using the standardized approach.
• |  | RWAMINT = portion related to capital required for market risk, composed of the maximum between the internal model and 80% of the standardized model, regulated by BACEN Circular No. 3,646 and No. 3,674.
• |  | RWAOPAD= portion related to capital required for operational risk, calculated based on the standardized approach.

III - Recovery Plan In response to the latest international crises, the Central Bank published Resolution No. 4,502, which requires the development of a Recovery Plan by financial institutions within Segment 1, with total exposure to GDP of more than 10%. This plan aims to reestablish adequate levels of capital and liquidity above regulatory operating limits in the face of severe systemic or idiosyncratic stress shocks. In this way, each institution could preserve its financial viability while also minimizing the impact on the National Financial System. IV - Stress testing The stress test is a process of simulating extreme economic and market conditions on ITAÚ UNIBANCO HOLDING’s results, liquidity and capital. The institution has been carrying out this test in order to assess its solvency in plausible scenarios of 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 elaboration of stress scenarios considers the qualitative analysis of the Brazilian and the global conjuncture, historical and hypothetical elements, short and long term risks, among other aspects, as defined in CMN Resolution 4,557. In this process, the main potential risks to the economy are assessed based on the judgment of the bank's team of economists, endorsed by the Chief Economist of ITAÚ UNIBANCO HOLDING and approved by the Board of Directors. Projections for the macroeconomic variables (such as GDP, basic interest rate, exchange rates 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. In addition to the scenario analysis methodology, sensitivity analysis and the Reverse Stress Test are also used. ITAÚ UNIBANCO HOLDING uses the simulations to manage its portfolio risks, considering Brazil (segregated into wholesale and retail) and External Units, from which the risk-weighted assets and the capital and liquidity ratios are derived. The stress test is also an integral part of the ICAAP, the main purpose of which is to assess whether, even in severely adverse situations, the institution would have adequate levels of capital and liquidity, without any impact on the development of its activities. This information enables potential offenders to 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 the institution’s risk appetite metrics. V - Leverage Ratio The Leverage Ratio is defined as the ratio between Tier I Capital and Total Exposure, calculated according to BACEN Circular 3,748, which minimum requirement is of 3%. The ratio is intended to be a simple measure of non-risk-sensitive leverage, and so it does not take into account risk weights or risk mitigation. d) Management Risks of insurance and private pension I - Management Structure, roles and responsibilities In line with good domestic and international practices, ITAÚ UNIBANCO HOLDING has a risk management structure that ensures that the risks arising from insurance and pension plans products are properly monitored and reported to the appropriate bodies. The management process of insurance and pension plans risks is independent and focuses on the specific nature of each risk. ITAÚ UNIBANCO HOLDING has committees to define the management of funds from the technical reserves for insurance and private pensions, to issue guidelines for managing these funds with the objective of achieving long term returns, and to define valuation models, risk limits and strategies on allocation of funds to specific financial assets. The members of these committees are not only executives and those directly responsible for the business management process, but also heads and coordinators of commercial and financial areas. II - Risks of Insurance and Private Pensions Insurance and pension plan risks arise from losses that contradict the expectations of ITAÚ UNIBANCO HOLDING linked to the operations of products sold in SUSEP supervised entities. The underwriting risk results from the use of methodologies and/or assumptions in the pricing or provision of products, which can materialize in different ways, contrary to the expectations of the product offered: (i) Insurance results from the change in risk behavior in relation to the increase in the frequency and/or severity of claims occurred, contrary to pricing estimates; (ii) Private Pension is observed in the increase in life expectancy or in deviation from the assumptions used in the technical reserves. Estimated actuarial assumptions are based on the past experience of ITAÚ UNIBANCO HOLDING, on market benchmarks and on the experience of the actuaries.
II.I - Effect of changes on actuarial assumptions |  |  |  |  |
To measure the effects of changes in the key actuarial assumptions, sensitivity tests were conducted in the amounts of current estimates of future liability cash flows. The sensitivity analysis, conducted semiannually, considers a vision impacts caused by changes in assumptions, which could affect the income for the period and stockholders’ equity at the balance sheet date. This type of analysis is usually conducted under the ceteris paribus condition, in which the sensitivity of a system is measured when one variable of interest is changed and all the others remain unchanged. The results obtained are shown in the table below:

III - Market, credit and liquidity risk
III.I - Market risk
Market risk is analyzed, in relation to insurance operations, using the following metrics and sensitivity and loss control measures: Value at Risk (VaR), Losses in Stress Scenarios (Stress Test), Sensitivity (DV01 - Delta Variation) and Concentration. In the table, the sensitivity analysis (DV01 – Delta Variation) is presented in relation to insurance operations that demonstrate the impact on the market value of cash flows when submitted to a one basis point increase in the current interest rate or indexer rate and one percentage point in the share price and currency.

III.II - Liquidity Risk
Liquidity risk is identified by ITAÚ UNIBANCO HOLDING as the risk of lack of liquid resources available to cover its current obligations at a given moment. For insurance operations, the liquidity risk is managed continuously by monitoring payment flows against liabilities, compared to the inflows generated by its operations and financial assets portfolio.
Financial assets are managed in order to optimize the risk-return ratio of investments, considering, on a careful basis, the characteristics of their liabilities. The risk integrated control considers the concentration limits by issuer and credit risk, sensitivities and market risk limits and control over asset liquidity risk. Thus, investments are concentrated in government and private securities with good credit quality in active and liquid markets, keeping a considerable amount invested in short-term assets, available on demand, to cover regular needs and any liquidity contingencies. Additionally, ITAÚ UNIBANCO HOLDING constantly monitors the solvency conditions of its insurance operations.
