1. Introduction

Banking system sustainability is indissolubly linked to risk-management and capital policies and mechanisms. The methods of identifying, assessing, controlling, mitigating and monitoring risk safeguard financial institutions in adverse situations and provide support for the generation of positive results that are recurring in the long run. Banco do Brasil (BB) considers essential risk and capital management to the process of decision-making, providing optimization of risk-return ratio to the operations.

Changes in the global financial environment, such as market integration through globalization, the emergence of new transactions and products, increasing technological sophistication and new regulations have made financial activities and their risks more and more complex.

Brazil’s participation in the Basel Committee on Banking Supervision stimulates the timely implementation of international prudential norms in the Brazilian regulatory framework.

Additionally, the lessons learned from financial disasters reinforce the importance of risk and capital management in the banking industry.

Those factors influence regulatory agencies and financial institutions to invest in risk management, seeking to strengthen their financial health.

In line with that perspective, BB has invested in the continuous improvement of its risk and capital management process and practices, in line with international market benchmarks of regulation and supervision.

BB remains continuously aligned with the best management practices, among which, the risk management architecture with multidimensional scope whose specificities are described in this report.

1.1 Objective

The current report aims to disclose the information related to risk management, to the measurement of the amount of Risk Weighted Assets (RWA) and to the Reference Equity (PR), in accordance with Circular nº 3,678, published by the Central Bank of Brazil (Bacen) on 10.31.2013, and it is aligned with the guidelines of Pillar III of Basel II. This report includes information about structures, processes and risk and capital management policies of Banco do Brasil (BB).

The measurement of PR and RWA considers the consolidation scope of the Prudential Conglomerate2.

That way, BB adopts a forward-looking position, by anticipating the capital necessity derived from the market conditions possible changes.

The Internal Controls Directorship (Dicoi) is responsible for the evaluation and certification of controls, validation of risk management models, evaluation of the Bank's internal control system and Compliance Risk management.

2.3 Strategic Definitions

2.3.1 Relevant Risks

BB has a process of risks identification, that results in the risks inventory and in the definition of the corporate set of relevant risks. That process is quite important for the risks and capital management, as well as for the business management.


16

BB`s risks inventory and the corporate set of relevant risks are annually revised, considering the risks incurred by the several business segments explored by the Bank or by its subsidiaries, which can affect Banco do Brasil`s Prudential Conglomerate Reference Equity (PR).

The classification of the relevant risks is based on quantitative and qualitative criteria.

The risks below are part of Banco do Brasil`s Prudential Conglomerate Relevant Risks Corporate Range:

Chart 4 - Banco do Brasil`s Prudential Conglomerate Relevant Risks Set Concept

Risk Concepts

Credit Risk Possibility of losses associated with the non-fulfillment by a borrower or a counterparty of their corresponding financial obligations according to negotiated terms, the devaluation of a loan agreement due to a drop in the borrower’s risk rating, a decline in gains or earnings, benefits granted in renegotiation, and recovery costs.

Credit Concentration Risk Possibility of credit losses arising from significant exposure to counterparty, a risk factor or groups of counterparties related by common characteristics.

Counterparty Credit Risk Possibility of a certain counterparty not fulfilling its obligations related to the settlement of transactions that involve trading financial assets, including those related to the settlement of financial derivatives.

The risk management process involves a continuous information flow, by observing the following stages:

Figure 4 -Decision making and process

It is important to mention that BB has a corporate tool to control and assess the Risks of Products, Services and Self-Service Channels (Carps), which is managed by Strategy and Organization Directorship (Direo), of mandatory usage by strategic units and external network, except for the subsidiary companies when there is the creation or revitalization of:

a) a product of service;

b) a type of product or service; and

c) self-service channels.

The usage of the tool aims to:

a) provide decision makers with information, by aggregating products, services and self-service channels with safety when they are launched in the Market, through the participation of the intervening areas;

b) identify and assess the several types of risks defined by the Bank for the creation and revitalization of a product/service/self-service channel;

c) search for control and compliance solutions that minimize risks;


20

d) promote synergy among managers and intervening parties of products/services/self-service channels, in a way it provides operational efficiency.

In the approval of new products, Carps corporate tool adopts the principle that a manager must assess risks and implemente controls, with the assistance of areas that are involved in the process, seeking a higher profitability and the reduction of losses.

The CMN Resolution nº 4,192, published on March 01, 2013, in its 3rd article, item ll, establishes that the calculation of Reference Equity (PR) must be performed in consolidated bases for institutions that belong to the Prudential Conglomerate.

The CMN Resolution nº 4,280, published on October 31, 2013, governs the preparation, disclosure and submission requirements of Prudential Conglomerate’s consolidated financial statements. This Resolution was amended by the CMN Resolution 4,517, on August 24, 2016.

According to the mentioned Resolutions, financial institutions and other institutions authorized by Bacen shall prepare financial statements in a consolidated basis, including data relative to the following entities, either located in Brazil or abroad, over which the institution has direct or indirect control:

a) financial institutions;

b) other institutions authorized by Bacen;

c) consortium administrators;

d) payment institutions;

e) companies that perform the acquisition of credit operations, including real estate, or credit rights, like factoring companies, securitization companies and exclusive purpose societies;

f) other legal entities domiciled in Brazil that have, as an exclusive objective, an equity interest in the entities mentioned in items a through e.

The CMN Resolution 4,280/13 also determines that investment funds in which the entities that compose the Prudential Conglomerate, under any form, take or retain substantial risks and benefits, shall be consolidated.

According to the CMN Resolution 4,517/16, investments in joint ventures must be accounted by the equity method from January 2017. They were previously proportionally consolidated.

4.1 Referential Equity (PR) Details

Tier 1

Common Equity Tier 1 Capital

The Bank’s Common Equity Tier 1 Capital is composed by Shareholders’ Equity and income accounts and it is deducted from Regulatory Adjustments.

On August 28, 2014, the Hybrid Instrument in the amount of R$ 8,100,000 thousand, was authorized by Bacen to compose the Bank’s Common Equity Tier 1 Capital.

Regulatory Adjustments

The Regulatory Adjustments are deductions from the Common Equity Tier 1 Capital of elements that can degrade its quality due to their low liquidity, difficulty to evaluate or reliance on future profits to be realized.

From January/17, the percentage of deduction of prudential adjustments listed below increased to 80%:

a) goodwill;

b) intangible assets constituted from October 1, 2013;

c) actuarial assets related to defined benefit pension funds net of deferred tax liabilities;

d) non-controlling interest;

e) investments, directly or indirectly, greater than 10% of the capital of unconsolidated entities similar to financial institutions, and insurance companies, reinsurance companies, capitalization companies and open pension entities (superior investments);

f) tax credits resulting from temporary differences that rely on the generation of future taxable profits or revenues for its realization;

g) tax credits resulting from tax loss of excess depreciation;

h) tax credits resulting from tax losses and negative basis of social contribution on net income.

According to CMN Resolution nº 4,192/13, these deductions will be gradually implemented, 20% per year, from 2014 to 2018, with the exception of deferred assets and funding instruments issued by institutions authorized to operate by Bacen which have already been fully deducted since October 2013.

Additional Tier 1 Capital

Hybrid Capital and Debt Instruments that meet the CMN Resolution nº 4,192/13 requirements can make up Tier 1, as long as they are authorized by Bacen.

(3) The base value for calculating the goodwill is composed of: R$ 309,956 thousand in the investment line.

For further information on the composition of the Reference Equity (PR), see the “Attachment 1 – Composition of the Reference Equity”.

4.2 Minimum Required Reference Equity (MRRE)

The Minimum Required Reference Equity (MRRE) is the equity required (capital volume required) of institutions, conglomerates, and other institutions authorized to operate by Bacen, to face the risks to which they are exposed due to the activities they are involved in, and it is definied by CMN Resolution nº 4,193/13.

The MRRE, corresponds to the application of the factor "F" to the amount of RWA, with:

a) 11% of RWA, from 10.01.2013 to 12.31.2015;

b) 9.875% from RWA 01.01.2016 to 12.31.2016,

c) 9.25% of RWA from 01.01.2017 to 31.12.2017;

d) 8.625% of RWA from 01.01.2018 to 31.12.2018; and

e) 8% of the RWA from 01.01.2019.

In determining the amount of risk-weighted assets (RWA), we consider the sum of the following portions:

a) RWACPAD concerning credit risk exposures subject to the calculation of capital requirements under the standardized approach;

b) RWAMPAD concerning market risk exposures subject to the calculation of capital requirements under the standardized approach, and,

c) RWAOPAD on the calculation of the capital requirement for operational risk under the standardized approach.

The scope of consolidation used as a basis for the verification of operational limits considers the Financial Conglomerate, from 10.01.2013 thru 12.31.2014, and the Prudential Conglomerate, defined by the CMN Resolution nº 4,280/13, as of 01.01.2015.

PR, Core Capital and Tier l Capital minimum limits, in line with the timetable to implant the new capital requirements, are the following:

4.3 Capital Adequacy Ratio

The Capital Adequacy Ratio was determined according to the criteria established by CMN Resolutions nº 4,192/13 and nº 4,193/13, which refer to the calculation of the Referential Equity (RE) and Minimum Reference Equity Required (MRER) in relation to Risk Weighted Assets (RWA), respectively.


34

The CMN Resolution n° 4,193/13 established the Core Capital Minimum Requirements (4,5% of RWA) and Tier l (5,5% of RWA until 12.31.2014 and 6%, as of 01.01.2015). In the first quarter of 2016, the Core Capital Additional was brought to pass, according to the CMN Resolution n° 4,193/13 requirements and Bacen Circular Letters n° 3,768/15 and 3,769/15.

4.4 Assessment of Sufficiency and Adequacy of Reference Equity (PR)

Banco do Brasil annually prepares and reviews its capital planning considering a minimum time horizon of 36 months and linking the matter to the business and economic guidelines from its Corporate Strategy, aiming to ensure that its capital is sufficient to support, beyond relevant risks, the business growth, so it guarantees the Institution solvency ratios, by also considering the stress scenarios, without compromising its result, being approved by the Board of Officers (CD) and the Board of Directors (CA) of BB.

The Capital Plan covers all entities, located in Brazil and abroad, which integrate Banco do Brasil’s Prudential Conglomerate, taking into account what is read in the CMN Resolution nº 4,280/13.

In order to subsidize the elaboration of the Capital Plan, the RE and RWA projections are referenced in regulatory aspects, strategic documents, business dynamics and technical information that were discussed at the Capital Forum.

Besides that, capital simulations, integrating risk and business stress testing results, based on one stress macroeconomic scenario, which is severe and based on plausible assumptions, in order to subsidize the elaboration of the Capital Contingency Plan (PCC).

The Capital Contingency Plan aims to ensure the alignment of the Bank to regulatory and prudential capital levels if the sources of capital defined in the Capital Plan are insufficient or not viable or even in the occurrence of unanticipated events.


35

The monitoring of the Capital Plan operation is made by the Capital Forum monthly and reported to the Senior Management. In that monitoring, the projections and the necessities of strategy realignment are assessed, considering the values that are realized, stress tests, eventual regulatory changes and the businesses expectancies.

In that context, the Bank assesses the projections based on the limits of each indicator and the deadline for any breach, as follows:

Chart 5 - Criteria and parameters for classification of the capital condition

Capital Index Period of noncompliance (months)

0 to 6 7 to 12 13 to 18 19 to 24 25 to 30 From 31st month

Common Equity Tier 1 Index CRITICAL ALERT SURVAILLANCE

Tier 1 Index CRITICAL ALERT SURVAILLANCE

Basel Prudential Index CRITICAL ALERT SURVAILLANCE

According to the chart above, the projections indicate that when extrapolating the Core Capital Ratio (ICP) or another indicator of capital, the Company will have enough time to promote strategic changes to avoid their extrapolation, according to the deadlines established for each indicator.

The capital status is monitored and reported at the Capital Forum and it must be reported to the strategic risk committees that are linked to the capital management structure (CEGAPC and CSGRC), which contains, whenever necessary, suggestions on capital contingency measures to be adopted.

Finally, for the capital management process, the Bank uses an indicator named Risk Adjusted Return (RAR), which aims to ensure the sustainability of BB`s growth in the long run, as well as to improve the Bank`s capital allocation, prioritizing the growth of businesses that generate profit in a way that is consistent to the capital consumption.

4.5 Leverage Ratio

In October 2015, Bacen Circular No. 3,748 came into effect and established the leverage ratio calculation methodology (RA), defined as the rate between Tier 1 capital and the total exposure of the institution. The RA aims to prevent excessive leverage of financial institutions and the consequent increase in systemic risk, with undesirable impacts on the economy.

5.1 Entities Linked to Banco do Brasil (ELBB) Assessment

The current regulation imposes the need for the Prudential Conglomerate integrated structure of risk management to identify and monitor the risks associated with the other entities controlled by its member or in wich they participate.

Besides the regulatory matter and considering the closer relationship between the risk management and strategy areas, the Bank has implemented a process that aims to oversee and assess its ELBB risk management, according to the activities or business segments, by issuing guidelines in order to promote alignment with the practices adopted by the Institution and contribute with reaching the best results.

The assessments are carried out through yearly cycles by means of the information provided by the companies, and quantitative and qualitative aspects of their risk management process are analyzed.

At the end of the assessments, reports are prepared and sent to the ELBB and their directors appointed by the Bank to consider the issued guidelines and take the necessary actions.

The assessments consolidated results are reported to Banco do Brasil`s risk and governance executive committees, CSGRC, CD, Coris, Coaud and CA.

6 Risk Management

6.1 Credit Risk

6.1.1 Specific Credit Policy

Banco do Brasil’s specific credit policy contains strategic guidelines to direct credit-risk management actions in the prudential conglomerate. It is approved by the Board of Directors and reviewed every year. It applies to all businesses that involve credit risk and is available to all employees. It is expected that the Subsidiaries, Affiliates and Investment companies define their paths from these guidelines, taking into account the specific needs and legal and regulatory issues to which they are subject.

The specific credit policy guides the credit process, including scope, credit risk taking, Credit collections and recovery, and credit risk management. It contains a comprehensive set of statements which encompasses all stages of credit-risk management at Banco do Brasil. Important topics addressed in Banco do Brasil’s specific credit policy are listed below:

a) concept of credit risk;

b) separation of duties;

c) guidelines for credit collections and recovery;

d) joint decisions;

e) risk appetite;

f) conditions for risk taking;

g) capital planning;

h) allowance and capital levels;

i) stress tests.

6.1.2 Mitigation Policy

Banco do Brasil is conservative towards credit risk. In conducting any business subject to credit risk, the bank’s general rule is to tie it to a mechanism that provides partial or complete hedging of risk incurred. In managing credit risk on the aggregate level, to keep exposure within the risk levels established by the Senior Management, the Bank has the prerogative to transfer or to share credit risk.

The use of credit risk mitigating instruments is stated in the Specific Credit Policy, present in strategic decisions, and formalized in credit rules, reaching all levels of the organization and covering all stages of credit risk management.

Credit rules provide clear, comprehensive guidelines for the operational units. Among other aspects, the rules address ratings, requirements, choices, assessments, formalization, control, and reinforcement of guarantees, ensuring the adequacy and sufficiency of the mitigator throughout the transaction cycle.

6.1.3 Management Strategies and Credit Risk Management Framework

Aligned with the objectives of credit risk management, the Board of Directors (CA) establishes the Specific Credit Policy and the Risk Appetite and Tolerance of Banco do Brasil, which covers guidelines for credit risk.

As of the guidelines approved by the CA, the credit-risk management strategies, described below are defined and aim to guide the actions in the operational level:


41

a) approving credit risk management models;

b) setting goals for timely payment, recovery, maximum loss, and quality of the loan portfolio;

c) setting risk limits, concentration limits and exposure with foreign countries limits; and

d) keeping appropriate levels of allowances and capital.

6.1.4 Measurement Systems

The credit risk measurement is made by means of several indicators: default, delays, portfolio quality, allowance for loans and lease losses, concentration, capital requirement, among others, which reflect the Bank`s risk appetite and tolerance.

The quantity and nature of the operations, the diversity and complexity of our products and services, and the volume exposed to credit risk require systematic measurement of credit risk at Banco do Brasil. The Bank has enough databases and corporate system infrastructure to ensure comprehensive measurement of credit risk.

6.1.4.1 Regulatory Capital Requirement

The Bank measures the regulatory capital requirement for credit risk coverage through Regulatory Simplified Standardized Approach, whose procedures for calculating the potion of risk-weighted assets (RWA) regarding exposure to credit risk (RWACPAD) were released by the Bacen through Circular nº 3,644/13.

Those procedures were implemented in a proprietary system that determines the capital requirements quickly and securely, allowing timely evaluation of the bank’s solvency under the regulator’s rules. The Bank uses Regulatory Capital information to assess the efficiency of capital allocation and planning.

6.1.4.2 Concentration

The Bank has the credit portfolio concentration risk measurement process and monitoring. Besides the monitoring of the portfolio different segments concentration level indicators, ascertained according to the Herfindahl-Hirshman Ratio, the impact of concentration in the capital allocation for credit risk.

6.1.5 Mitigating instruments

When accepting guarantees in loans, preference is given to guarantees which help the operation self-liquidate.

In order to accept a guarantee, the maximum value considered is reached by applying a certain percentage on the value of the goods or right. Below, the percentages used are shown:

(4) Contract of deposit / Transfer of Customer funds (5) Exclusive or retail. (6) Excpet in Rural Product Notes Transactions (CPR). (7) According to certain characteristics, real state, vehicle, machinery and equipment can be received with highest percentage of guarantee.

The credit rights guarantees represented by financial investments must be internalized at the Bank and are blocked by the institution. This blockage must remain until the operation is concluded.

Besides credit assignment or credit rights assignment clauses, the credit instrument, for linked mitigators, the credit instrument has a guarantee reinforcement clause to ensure, for the duration of the operation, the coverage percentage agreed on when it was contracted.

Considering the credit risk mitigating instruments defined in articles 36 to 39 of Bacen Circular nº 3,644/13, the following table shows the total mitigated value in terms of exposure, weighted by risk factor, and segmented by type and FPR mitigator.

(2) Credit risk mitigation instrument represented by payroll discount transfers was established by Bacen Circular 3,714, which became effective on Aug /14.

6.1.5.1 Processes for Monitoring the Effectiveness of Mitigators

Monitoring the effectiveness of mitigators is part of the Bank’s credit risk management processes. We quote, as an example, monitoring exposures subject to credit risk, the risk ratings of loans, and credit collection and recovery.

The processes of monitoring credit risk exposure and rating loans risks produce important information for verifying the effectiveness of mitigating instruments. The low default ratio in certain segments of the credit portfolio and the lowest level of


43

allowances in certain transactions may mean that the existence of guarantees tied to exposure reducing credit risk and capital requirements for its coverage.

6.1.6 Exposure to Credit Risk

The table below shows the concentration levels of the ten largest customers in relation to total transactions with credit granting feature.

The following table shows credit risk average exposure of individual portfolios (PF) and businesses (PJ).

It is important to mention that, in Banco do Brasil, the concepts that were used for the Credit Releasing and Loan Portfolio - Broad Concept are:

a) BB’s Loan Portfolio – Broad Concept: BB`s Classified Portfolio (BB`s Internal Portfolio + BB`s External Portfolio), BB`s Collaterals and BB`s Bonds and Securities; and

b) Releasing Credits: They stand for portions of credit limits that can not be cancelled unilaterally by BB, such as the limits of special checks and credit cards (balance of credit to be released in limits that can not be cancelled) and the portions on the timetable of releasing that can not be cancelled unilaterally by BB, such as: Finame, BNDES with the timetable of releasing resources (balance of credits to be released in timetable operations).

6.1.7 Exposure to counterparty credit risks

Banco do Brasil admits assuming counterparty credit risks with clients who have been previously analyzed by the risk calculation methodology, with a credit limit applicable to their profile established, subject to the existence of a sufficient operational margin to cover such operations.

In this way, the counterparty credit risk exposures fall in line with other exposures in the customer’s loans on the credit limit assigned to it.

These types of operations affect the client’s credit risk according to the estimated value of the counterparty credit risk exposure in the event of a default, applicable credit risk mitigators being taken into consideration, such as the adjacent asset issuer risk, the volatility of the asset, deposited collaterals, the percentage subtracted from the assets used as collateral (haircut), and the rules for additional collateral margin calls, according to the characteristics of the operation performed.

In operations conducted via Clearing Houses (Clearings), there is a risk transfer, where the value of the operations is reflected in the credit limit of the Clearing House.

For operations that are subject to the counterparty credit risk, Banco do Brasil follows what is quoted by Bacen Circular n° 3,068/01, considering the risk as a parameter for the calculation of the market value adjustment of such exposures, affecting the result of the period or in an account apart from the Net Equity, according to the classification of the exposure.

Below is the notional value of contracts subject to counterparty credit risk to be liquidated in clearing house liquidation systems, in which clearing houses acts as central counterparty.

6.1.8 Acquisition, Sale or Transfer of Financial Assets

It is BB’s policy to assign credits from non-performing loans, recorded in losses and for which the bank has full risk, after all collection procedures defined in the collections and credit-recovery process have been exhausted, and the selected transactions have reached the savings point, that is, the cost-benefit ratio, does not justify keeping the transactions under collections at the commercial bank.

Credit assignment is also used punctually to dispose of specific credits, when such an operation is considered a viable alternative for its recovery, even if partial.

It should be noted that, in the 4th quarter of 2017, there were no assignments of credits to Ativos S.A.

The procedures to acquire financial assets are similar to the standard adopted by the market, which covers the assessment of assigning institution credit risk, the acquired operations and the corresponding debtors. The financial assets acquisitions aim to increase the Bank`s credit portfolio diversification.

In compliance with the CMN Resolution nº 3,533 and the related norms, as of January 2012, the accounting registrations started being made by considering the substantial transfer or retention of the acquired financial assets risks and benefits.

6.2 Market Risk

6.2.1 Market Risk Policy

The Bank establishes policies and strategies for managing market and liquidity risks, and to manage derivative financial instruments. These policies and strategies determine the Company’s operating guidelines in these risks management process.

The market and liquidity risks management process uses mechanisms set forth in regulatory systems which detail the operational procedures that are necessary to implement the organizational decisions concerning the Company’s business and activities and to meet legal, as well as regulatory and oversight bodies’ requirements.

6.2.2 Management Strategies and Market Risk Framework

It is relevant to mention that, for the market risk management, systems are used to guarantee that positions registered in negotiable and non-negotiable portfolios are measured, monitored, and controlled, as are operations aimed at meeting the hedge objectives established.

Banco do Brasil uses statistical and simulation methods to analyze the market risk of its exposures. Among the metrics used in the application of those methods, we highlight the following:

a) Sensitivities;

b) Value at Risk (VaR); and,

c) Stress.

Sensitivity metrics simulate the effects in the value of exposures resulting from variations in the level of market risk factors.

VaR and Stress are metrics used to estimate the potential loss under routine or extreme market conditions, respectively, dimensioned in monetary values, under a confidence interval and time frame.

The risk factors used in VaR metrics to measure the market risk of exposures are classified into the following categories:

a) interest rates;

b) exchange rates;

c) share prices; and,

d) commodity prices.

The VaR metrics performance is monthly evaluated by a backtesting process.

6.2.3 Hedge Policies

With respect to hedging policies adopted for market and liquidity risks management, the objectives to be achieved with hedging operations on a consolidated basis are defined, assuring the individual effectiveness of each transaction, subject to the regulations of each jurisdiction.

6.2.4 Derivative Financial Instruments

At the Bank, the derivative financial instruments are used for hedging own positions, meeting the clients` needs and for intentional positions making, considering limits, competence and procedures that were previously established.


57

The tables below represent the total exposure to derivative financial instruments by category of market risk factor, segmented into positions bought and sold in the following way:

a) Derivative financial instrument transactions carried out with a central counterpart, subdivided into those in Brazil and those abroad; and

b) Derivative financial instrument transactions carried out without a central counterpart, subdivided into those in Brazil and those abroad.

6.2.5 Negotiable Portfolios

The Negotiable Portfolio is divided into groups and books, always observing the internal rules, approved by the Risk, Assets, Liabilities, Liquidity and Capital Management Superior Committee (CSGRC), which establish the objectives, the composition, the financial limits and market risk limits for each group or book.

The main types of limits used for the market risk management are: Value at Risk (VaR) and stress tests.

In the case of the Negotiable Book VaR limits, aiming to evidence the level of the market risk that is generated by the exposures and the corresponding impact on the capital requirement for its coverage, the VaR and Stressed VaR metrics are considered.

For measuring the VaR of the Negotiable Portfolio, Banco do Brasil adopts the Historical Simulation technique, and the following parameters:

a) Total VaR: (VaR + Stressed VaR) x Multiplier, where:

i) VaR: the potential expected loss considering a series of 252 daily shocks (business days), a confidence level of 99% and a holding period of 10 business days (Central Bank of Brazil, Circular 3,568/11);

ii) Stressed VaR: the potential expected loss considering series of daily shocks under stress scenarios within 12 month periods starting at January 2nd, 2004, a confidence level of 99% and a holding period of 10 business days (Central Bank of Brazil, Circular 3,568/11); and

iii) Multiplier: M, as defined by Central Bank of Brazil, Circular 3,568/11.

The following table shows the total value of the Negotiable Portfolio by relevant market risk factor, divided into positions purchased and positions sold:

6.2.6 Non-negotiable Portfolios

The Financial Conglomerate own position operations not classified under the Negotiable Portfolio are considered components of the Non-negotiable Portfolio. It`s noticeable that the own positions held by the companies that are not a part of the Financial Conglomerate cannot be classified under the Negotiable Portfolio.

In accordance with best market practices and the requirements of regulators, the Bank sets policies for managing market risk, including interest rate risk transactions classified in the non-negotiable portfolio. These policies are in accordance with the strategic guidelines of the institution and the general objectives of the management process and predict:

a) control of exposures by setting limits; b) portfolio management considering the best risk-return relationship and the

internal and external scenarios; c) performing operations to reduce the risks arising from changes in market value

or cashflows of the assets and liabilities; d) management of foreign exchange exposure to minimize the effects on the

outcome of the institution; e) assessment of impacts on exposures during the creation or modification of

products and services; and f) performing monthly stress testing of interest rate exposures.

The Non Negotiable Portfolio (Banking Book) is divided into groups and book, observing the internal rules approved by the Risk, Assets, Liabilities, Liquidity and Capital Management Superior Committee (CSGRC), which establish the objectives, the composition, the financial limits and the market risk limits for each group or book.

Banco do Brasil uses the Economic Value of Equity (EVE) metric, in order to calculate banking book interest rate risk.

EVE consists in estimating the variation of the economic value of assets, liabilities and derivative instruments of the Institution, comparing the value that was obtained through the use of domestic interest rate shock scenario with the value that was calculated in the current rates scenario.

Among other aspects, it is relevant to highlight that the EVE calculating metric:

a) includes all the operations that are sensitive to the variation of interest rates and uses risk measuring techniques and financial concepts that are widely accepted;


61

b) considers data relevant to rates, deadlines, prices, optionalities and other information that was adequately specified;

c) requires the definition of adequate premises to turn positions into cash flows;

d) measures the sensitivity to changes in the temporal structure of interest rates, between different rate structures and premises;

e) is integrated in the daily practices of risk management;

f) allows the simulation of market extreme conditions (stress tests);

g) make it possible to estimate the need of capital for risk coverage.

In order to deal with the products that do not have a defined maturity, Banco do Brasil adopts statistical and econometric methods, from the literature to analyze temporal series, more specifically the methods called ARIMA (Autoregressive, Integrated and Moving Averages).

Such methods assume the hypothesis that a retrospective behavior of the variations that are observed in the balances are important information for the prediction of the future behavior of the cash flow bailouts (random variable of interest) of the balances of funding products that are under a reference. So, those methods assume as feasible the possibility of future occurrence of fluctuations of balances (financial amount of partial bailouts) with a range that is similar to the ones that are observed in the historical series.

The table below shows the impact on the result or on the value assessment of the institution due to shocks in interest rates segmented by risk factors:

6.2.7 Risk measuring systems and communication and information processes

The market risk measuring process uses corporate systems and the application “Riskwatch”, which primarily aim to:

a) consolidate managerial information for market risk management;

b) simulate market scenarios; and

c) calculate market risk measures.

Riskwatch functions that deserve special emphasis are:

a) the calculation of market risk indicators, such as Value-at-Risk (parametric and nonparametric), duration, yield;

b) the elaboration of cash flow reports, either consolidated or by product, marked to market or nominal;


62

c) the determination of the portfolio sensitivity to the fluctuations in national and international interest rates;

d) the calculation of the theoretical result of portfolios after the application of historical and stress scenarios; and

e) the elaboration of the reports on the mismatching of maturities, rates, indexes and currencies.

At the Bank, the own positions are segregated in Trading Portfolio and Non-Trading Portfolio. The criterion to classify the operations in the Trading Portfolio is defined by CSGRC, which also sets, in the sphere of the Prudential Conglomerate, the policy for the classification of operations in the Trading Portfolio.

The own positions held by companies that are not part of the Prudential Conglomerate are not subject to the classification in the Trading Portfolio.

For the market risk management process, the Bank makes use of a structure of management groups and books, both for the domestic area and for the international area, with specific objectives and limits of exposure to risks.

Regarding the limits of exposure to market risks, the CSGRC establishes the following classification criteria:

Global limits: applied to the Trading and Banking Book Portfolios, to the set of transactions subject to capital requirements and to the interest rate risk in the Banking Book Portfolio (RTJBB) and approved by CSGRC, The main metrics used for management are Value-at-Risk (VaR), stress and financial volume, both for trading and for banking book, and EVE, for banking book.

Specific limits: applied to the management groups and books of the Trading and Banking Book Portfolios or to both Portfolios, to the market risk factors of transactions subject to capital requirements and to the market risk factors sensitive to the interest rate risk in the Banking Book Portfolio (risk factors of RTJBB) and approved by the CEGRC, The main metrics used for management are Value-at-Risk and stress, both for trading and for banking book, and EVE, for banking book.

Operational limits: applied to transactions that make up the management groups and books, enabling the disclosure of the effective risk level of assumed exposures and aiming to ensure compliance with the strategies and the global and specific limits established, They are defined and approved by Diris presenting as main metrics the Value-at-Risk and operating bands of exposure to market risks.

Diris reports the consumption of the specific and operational limits to the managers of the groups and books of the Trading and Banking Book Portfolios daily. It reports the consumption of overall limits to the strategic committees monthly, through the Market and Liquidity Risk Management Report and Risks Dashboard.

In case limits are exceeded, Diris, responsible for controlling and monitoring the portfolio, issues a document called "Limit Exceeding Form". The managers of groups and books should submit their reasons for exceeding limits and specify the deadline for regularization. In turn, the hierarchical level with the authority to manage the case should issue an opinion on the manager's pronouncement. The team responsible for monitoring the limit is responsible for keeping track of the categorization actions.

6.3 Liquidity Risk

6.3.1 Liquidity Risk Policy

Banco do Brasil has a liquidity risk policy which comprises the guidelines of the Company in its liquidity risk management process.

The liquidity risk policy presents the liquidity risk of operations recorded on assets, liabilities and offset accounts that are carried out in the financial and capital market, as well as possible contingent or unexpected exposures, taking into account different time horizons and estimating losses associated with different scenarios, internal and external, including stress scenarios. It also considers funding strategies that provide adequate diversification of funding sources, maturity and currency terms and liquidity contingency plan.

6.3.2 Liquidity Risk Processes and Strategies

BB maintains appropriate levels of liquidity for its commitments in Brazil and abroad, resulting from its broad and diversified depositor base and the quality of its assets, a well-diversified branches network and its ability to access the international capital market. Strict control over liquidity risk is in accordance with the Liquidity Risk Policy established by the Board of Directors, complying with the requirements of Brazilian banking supervision and that of the other countries where BB operates.

The liquidity risk management process involves continuous flow of information, according to the phases presented in the risk management process chapter.

BB’s liquidity risk management segregates liquidity in Reais from liquidity in foreign currencies. The instruments used in the management are:

a) Liquidity Projections;

b) Stress Tests;

c) Liquidity Risk Limits; and

d) Liquidity Contingency Plan.

The liquidity risk management instruments are monitored periodically and reported in BB’s strategic committees.

The Liquidity Projections ensure a forward-looking assessment of the effect of mismatching between funding and investments, in order to identify situations that could compromise the liquidity of the Institution, taking into account both budgetary planning and market conditions.

Liquidity Projections are assessed periodically under alternative and stress scenarios. If the result of any of these liquidity projection scenarios remains below the adopted liquidity level limit, then the previously established Contingency Measures Potential are put into effect, in order to recover the Institutions’ liquidity.

Furthermore, Banco do Brasil uses the following metrics for Liquidity Risk limits:

a) Liquidity Reserve (RL); b) Liquidity Cushion; and c) Availability of Free Resources Indicator (DRL); and d) Liquidity Coverage Ratio (LCR).

Liquidity Reserve is the metric used in short-term liquidity risk management. It is the minimum level of high liquidity assets the Bank must maintain, compatible with the risk exposure arising from the nature of its operations and market conditions.


64

The following figure shows BB’s monthly monitoring of the Liquidity Reserve in local currency.

65

The Liquidity Cushion limit aims to monitor the daily observed liquidity in addition to the daily monitoring of liquidity projections in various scenarios: base and stress, using the Liquidity Reserve limit.

The Availability of Free Resources indicator (DRL), used in planning and in the execution of its annual budget, is intended to ensure a balance between funding and the investment of resources in the commercial portfolio and ensure liquidity financing with stable resources.

The DRL limit used to guide the execution and planning of the budget, according to the funding and investment goals, is defined annually by the CEGRC (Risk Management Executive Committee), and its monitoring occurs on a monthly basis.

Figure 7 - DRL Indicator

The Liquidity Contingency Plan, on its turn, establishes the strategy, procedures and responsibilities to be adopted in liquidity stress situations. In that case, one or more contingency measures may be adopted so that the institution can assure its payment capacity. The potential of liquidity contingency measures is verified monthly.

The Liquidity Reserve and the LCR are used as a parameter to identify a liquidity contingency and to activate the Liquidity Contingency Plan, being monitored daily.

6.3.3 Liquidity Coverage Ratio (LCR) Calculation

The Liquidity Coverage Ratio (LCR) is a requirement financial institucions classified in S1 segment, in accordance with CMN Resolution nº 4,401/15.

The LCR calculation follows the standardized stress scenario model established by the Central Bank of Brazil (Bacen) through Circular nº 3,749/15. This model complies with international guidelines and aims to guarantee the existence of sufficient high quality liquid assets to support a financial stress scenario with a 30 - day term.


DRL DRL Limit


66

The regulatory stress scenario used to calculate the LCR considers idiosyncratic and market shocks that results in:

a) partial funding loss from:

i. retail operations;

ii. wholesale operations without collaterals.

b) reduction in the institution`s ability to raise short - term funds;

c) additional outflow of funds under agreement due to three levels credit risk downgrade, including additional collateral requirement;

d) increase in the volatility of prices, rates or indexes that impact the quality of a collateral or the potential future exposure of derivative positions, resulting in the application of greater discounts to a collateral or additional collateral call, or other demands for liquidity;

e) withdrawals higher than expected in lines of credit and liquidity granted; and

f) the potential need to repurchase bonds issued or honor non-contractual obligations aiming to mitigate reputational risk.

Thus, LCR is the ratio between high quality liquid assets (HQLA) and the expected total net cash outflow for the next 30 days, as the following formula shows:

𝐿𝐶𝑅 = 𝐻𝑖𝑔ℎ 𝑄𝑢𝑎𝑙𝑖𝑡𝑦 𝐿𝑖𝑞𝑢𝑖𝑑 𝐴𝑠𝑠𝑒𝑡𝑠 (𝐻𝑄𝐿𝐴)

𝑁𝑒𝑡 𝐶𝑎𝑠ℎ 𝑂𝑢𝑡𝑓𝑙𝑜𝑤𝑠

Where: Net Cash Outflows = Cash Outflows (-) Cash Inflows Cash Inflows is limited to 75% of cash outflows

The HQLA are assets that remain liquid in markets during periods of stress, which are easily and immediately converted into cash with low or without losses, it has no impediments, with a low risk and whose pricing is easy and right, i.e. that meet the minimum requirements set by the regulator (Circular 3,749, from March 5th 2015).

Net cash outflows are the cash outflows minus the cash inflows. Cash outflows are estimated by multiplying the balances of the various categories of obligations and commitments, recorded to liabilities or off balance sheet, by weighting factors.

Cash inflows are estimated by the multiplication by weighting factors, the balances of the various categories of receivables without default, for which there is no expectation of counterparty failure in the next 30 days.

The following table presents the LCR implementation schedule in Brazil, in which the minimum requirement of the indicator will increase gradually to reach 100% from January 2019.

The average Banco do Brasil LCR for 4Q17 recorded to 234.5%, compared to 260.2% recorded in the previous quarter. The change observed in the ratio was mainly due liquidity management of BB Conglomerate.

High Quality Liquid Assets are represented mainly by Brazilian Government securities in addition to the amounts considered as a return from compulsory reserve collected to the Central Bank of Brazil. The average HQLA volume for the quarter was R$ 116.3 billion, compared to the average value of R$ 114.3 billion recorded in the previous quarter.

Cash Outflows, considering the regulatory stress scenario, recorded to an average amount of R$ 110.3 billion in 4Q17 and were mainly composed by (approximately 74%):

a) retail and non-collateralized wholesale funding, as presented on items 2 and 5 of the above table;

b) credit card payments to merchants, as presented on item 14 of the above table.

In the previous quarter Cash Outflows reached an average amount of R$ 102.2 billion.

Cash Inflows amounted to an average value of R$ 60.7 billion in 4Q17. The value of

cash inflows from loans amounted for R$ 12.6 billion, or 21% of total Cash Inflows

(item 18). In the previous quarter the average value of Cash Inflows amounted for R$

58.2 billion.

Accordingly, it is possible to conclude that Banco do Brasil has sufficient liquid assets to support the standardzided stress scenario proposed by the regulator.

The current calculation of BB LCR has some limitations:

a) absence of amounts given or received as collateral and margin calls linked to derivative financial instruments;

b) absence of all subsidiaries that forms BB Prudential Conglomerate (the current calculation considers more than 99% of this view in terms of total assets);

c) absence of cash outflows related to market maker operations; d) segregation of cash inflows referring to directed credit in operations that should

be and should not be redirected in 30 days; e) segregation of cash inflows related to BB deposits in deposits related to and not

related to trade finance;

An action plan is underway aiming to do all needed adjusts.

6.3.4 Liquidity Risk measuring systems

Liquidity risk measuring process makes use of corporate systems, the Riskwatch application and the Statistical Analysis System - SAS. The main objectives of these applications are:

a) consolidate management information of the Bank, ascertaining and providing information for liquidity risk management and for assets and liabilities management;

b) provide liquidity risk measurements (products/cash flows by currency and index), as well as assets and liabilities management.

The main functions of the RiskWatch application are the same mentioned for market risk.

The SAS tool is responsible for the current calculation of the LCR. The tool combines extractions from the corporate system called Liquidity Risk Management (GRL) with corporate tables, to calculate the indicator.

The GRL system is the corporate solution under development that covers all the stages of calculation and reporting of the LCR indicator, from the extraction of data, classifications and parameterizations needed and the report generation as demanded by Central Bank of Brazil.

The measurements and report terms of management tools adopted in the liquidity risk management process, presented in the previous chapter, are performed in accordance with the models and methodologies approved by the strategic risk committees.

Diris and the areas responsible for liquidity management assess the consumption of limits for local and foreign currency liquidity daily. In the event of extrapolations, they are treated according to established governance, including both the Liquidity Forum and strategic risk committees.

The communication of the Bank liquidity risk management to Senior Management occurs in the ordinary meetings of the strategic risk committees, as it happens to the “Risk Dashboard”.

Regarding the assessment of capital requirement, it is not the practice to allocate capital to cover liquidity risk. The effects of liquidity risk are given in cash availability, even if the company has a robust capital structure.

6.4 Operational Risk

Banco do Brasil manages operational risk by segregating risk and business management functions and by adopting the best practices on risk management, in accordance with rules and regulations of supervision and banking regulation.

There is an operational risk management structure and policies approved by the Board of Directors compatible with its business model and the complexity of its processes, products and services.

In line with the strategy to reduce operational losses and to maintain the level of exposure to operational risk, observing the established appetite and tolerance, a Global Limit is defined annually, which is segmented into Specific Limits, distributed by the operational risk categories and the responsible managers of those risks.

The Governance of operational risk involves the Board of Directors, the Superior Committee for Assets, Liabilities, Liquidity, Capital and Risk Management (CSGRC) and the Executive Committee for Internal Controls and Risk Management (CEGRC).

6.4.1 Policies

The Bank adopts a Specific Operational Risk Policy that contains guidelines to the various areas to ensure the effectiveness of the operational risk management model. The subsidiaries, affiliates and holdings are expected to define their directions based on these guidelines, considering the specific needs and also legal and regulatory aspects to which they are subject.The Bank also has other policies that make up the list of policies associated to the management of the operational risk:

a) Prevention and Combat against Money Laundering, Terrorism Financing and Corruption;

b) Business Continuity Management;

c) the Bank Relationship with Suppliers;

d) Legal Risk Management; and

e) Information Security.

6.4.2 Operational Risk Management Process

The roles and responsibilities for operational risk management are defined in accordance with the Lines of Defense Model that involves the entire Organization at its various levels.

The 1st Line is composed of the organization's production chain, responsible for identifying the risks of its processes, products and services, establishing the controls to mitigate them and monitor their effectiveness and performance.

The 2nd Line of Defense is organized to: advise 1st Line managers in the identification and mitigation of risks; to evaluate the identified risks by quantifying the exposure to operational risk in order to consider the impact on the Bank's business; measure; control the Bank's exposure; monitor the adequacy and effectiveness of operational risk management; and report their results.

The 3rd Line of Defense is the Internal Audit, responsible for the independent evaluation of governance, risk management and internal controls.

Risk identification relies on the corporate dictionary of operational risk that has the risks mapped and classified into four levels, in order to facilitate and standardize the process. From the identified risks, certification and evaluation are carried out, where


70

the calculations of the risk criticity and its potential impact are executed and mitigation actions must be implemented. To make operational risk management more effective, priority is given to the most relevant losses and the risks of greater criticity, which are also accompanied by the highest levels of governance.

The Operational Risk Panel is the instrument used to manage operational losses and to follow the framework of the Global Limit and Specific Limits established, being reported monthly to CEGRC and CSGRC, and quarterly brought to the CA's attention. The panel presents monthly and annual position, with the respective detail of the limits, monitoring the history of operational losses and main occurrences by category.

The following table presents the monitoring of the operational losses of the Bank held by categories of risk events, in percentage terms:

6.5 Environmental Risk

6.5.1 Environmental Responsibility Policy

In compliance with requirements of CMN Resolution nº 4,327, dated 04.25.2014 and the SARB Regulation (Self - Regulation Bank) n.14, dated 08.28.2014, of the Brazilian Federation of Banks (Febraban), Banco do Brasil established Specific Socio-Environmental Responsibility Policy (PRSA).

The PRSA guides the behavior of the Bank, which, in turn, guided by the principles of relevance, proportionality and efficiency, commits itself to collaborate with subsidiaries, affiliates and simple participations in order to define their guidelines, taking into account the specific needs and legal and regulatory aspects to which they are subject. The Bank's Specific Credit and Relationship with Suppliers Policies also have socio-environmental orientations.

6.5.2 Environmental Risk Management Strategies

The Bank’s performance is based on policies and processes approved by the Senior Management and the management structure segregates the risk management process from the other corporate processes.

The Bank adopts socio-environmental risk governance structure compatible to its size, business type, complexity of the products and services, and relations established with the interested public.

The socio-environmental risk management structure aims to identify, classify, evaluate, monitor, mitigate and control socio-environmental risk and includes Directorships and Units with defined roles and responsibilities, with the participation of the Management Bodies and the Strategic Committees.

In the socio-environmental risk management model, the Directorships and Units provide necessary information to the management so that Diris can identify exposures and advise the decision-making process.


71

The Bank also has processes that contribute to the implementation of social and environmental responsibility actions based on the Dow Jones Sustainability Index (DJSI), Corporate Sustainability Index (ISE) of the companies listed in B3 (Brazil, Stock

Exchange and Counter), Agenda 30, Sustainability Forum and Equator Principles.

6.6 Other Risks

In the model of the strategy, reputational, Complementary Pension Fund Entities and Private Health Insurance Plan Operators for Employees Risk (EFPPS) and legal risks management, the intervening directorships provide the necessary information for the management, so the risk area can identify exposures and assist the decision-making process in a risk situation.

The way the Bank acts is based on policies and processes approved by the Senior Management. The report and risks control is periodically made and the results are communicated to the competent instances.

6.6.1 Strategy Risk

The Bank defines strategy risk as the possibility of losses derived from adverse changes in the business environment or the use of inadequate assumptions in strategic decision making.

The strategy risk management structure segregates the risk management process from the corporate strategy management process in Banco do Brasil, highlighting the responsibility of the involved areas and aiming to ensure the sustainable return to shareholders.

The strategy risk management policy guides the corporate resources applied to its management, defines the scope and specifies the need to establish governance tools.

BB periodically monitors indicators that reflect the strategy risk level incurred by the Institution. The control of those indicators is made by pre-established tolerance limits, with report to the senior management, in order to ensure that the risk remains in the acceptable levels.

As a way of promoting proactive management in decision making, the Bank’s strategic movements are also monitored, with a risk classification that is phased in three stages, prior to approval, in the development/implementation phase, and in the post-implemented pahse.

The monitoring of the performance and the strategic risks of these movements, associated to the scenario analysis, qualifies the decision making and allows the correction of course, when necessary.

In addition to the macroeconomic and financial industry scenarios, idiosyncratic scenarios are also considered, with the objective of better assessing threaths and opportunities, internal strengths and weakness, to mitigate risks in strategic decisions. In addition, high-severity scenarios, used every six months, are also defined for the purpse of strategy risk stress testing.

6.6.2 Reputational Risk

The Bank defines reputational risk as the possibility of losses derived from the negative perception about the Institution from clients, counterparties, shareholders, investors, governamental agencies, the community or supervisors that can adversely affect the


72

business sustainability. This concept is subdivided into the categories “businesses and relations” and “controls and compliance”.

The reputational risk management structure segregates the risk management structure from the brand management corporate processes, evidencing the responsibility of the areas that are involved and aims to ensure a sustainable feedback to shareholders.

The reputational risk management policy guides the corporate resources applied to its management, defines the scope and specifies the need to establish governance tools.

BB periodically monitors indicators that reflect the reputational risk level incurred by the Institution. The control of those indicators is made by pre-established tolerance limits, in order to ensure that the risk remains in the acceptable levels. The objective of this process is to promote the proactive management in decision making.

In the category “businesses and relations”, indicators about the quality of mentions in the press, social media, internet,digital consumer complaints channels, customer experience surveys and the perception from investors are monitored.

In the category “controls and compliance”, indicators related to the perception from regulators, the occurrences registered in the external ombudsman, the quality of the anti-money laundering process, the allegations of corruption and consumer service are monitored.

Besides the indicators monitoring, the Bank works on reputational risk stress tests to assess the impact of adverse or severe scenarios monthly.

6.6.3 Complementary Pension Fund Entities and Private Health Insurance Plan

Operators for Employees Risk (EFPPS Risk)

The EFPPS risk is defined by the possibility of a negative impact arising from the mismatch between actuarial liabilities and assets of closed private pension fund entities and private health insurance plan operators for employees.

The EFPPS risk is managed based on three dimensions: sponsor, pension fund plans and heatlh insurance plans. To ensure the identification and monitoring os the aspects that contribute the most to the increase of the risk, assests and liabilities are evaluated in a segretated way and receive shocks, os scenarios of normality and stress.

In the management process, indicators are used, for which “critical bands” are established, the monitoring of which is periodically reported to senior management.

It is important to mention that the EFPPS risk management structure segregates the risk management process from Banco do Brasil`s corporate processes, by establishing the responsibility of the areas that are involved, with the engagement of the Management Board and the Strategic Committees.

6.6.4 Legal Risk

As it is regulated by the CMN Resolution 4,557, from 02.23.2017, the legal risk is part of the operational risk definition, so the operational risk management structure, when defining its model, predicts its management, which have already been detailed in the item 6.4 of this report.


73

6.6.5 Model Risk

6.6.5.1 Specific Risk Policy Model

This Policy guides the management of model risk, which deals with the possibility of

losses arising from the inadequate development or use of models, due to the

inaccuracy or insufficiency of data or the incorrect formulation in its construction, which

may adversely affect the sustainability of business.

6.6.5.2 Strategies for Model Risk Management

The model risk management structure aims to identify, measure, evaluate, monitor,

report, control and mitigate the risk, considering the nature of operations, complexity

of products and processes, as well as the dimension of the Bank`s model risk

exposure, which is reported to Senior Management.

Therefore, the Bank has implemented a specific structure for the activities of evaluation

and monitoring of models, which is segregated from development activities,

independent validation and Internal Audit, preserving the independence of the lines of

defense.

6.6.6 Contagion Risk

6.6.6.1 Contagion Risk Specific Policy

The Contagion Risk Specific Policy establishes the guidelines to handle the possibility

of a negative impact on the Prudential Conglomerate capital, liquidity or reputation,

derived from adverse events in the relevant ELBBs that are not part of the Prudential

Conglomerate.

That policy works together with the Equity Investments Specific Policy which aims to

guide the Prudential Conglomerate behavior in relation to the businesses that involve

direct and indirect equity investments, in Brazil and abroad, by observing governance,

corporate strategy and business aspects.

6.6.6.2 Contagion Risk Management Strategies

Banco do Brasil, as the leading institution of the Prudential Conglomerate, has an established process to supervise the risk management structure of its Linked Entities (ELBB), ensuring the effectiveness and integrity of the business model by instituting corporate governance mechanisms capable of promote the alignment of the guidelines and performance of the Linked Entities to those of the conglomerate.

The contagion risk management model aims to identify and follow the risks that are associated to the ELBBs, by means of supervising the risk governance which is implemented in the companies, by issuing guidelines and technical advice to improve their risk management structure in relation to the deficiencies that have been found.

Besides the oversight process, the Contagion Risk management also covers the issuing of technical advice about the sale, acquisition, merger and incorporation of companies by Banco do Brasil, ensuring the mitigation of Contagion Risk.

The supervision process aims at knowing and analyzing the corporate risk

management of the Entities Linked to Banco do Brasil (ELBB), in order to allow the

identification and monitoring of its risks, with the issuance of guidelines and feedback

to improve its management structure of risks in relation to identified deficiencies,

ensuring the mitigation of Contagion Risk


74

6.6.7 Compliance Risk

Compliance risk is defined as the possibility of financial or reputational loss resulting from failure to comply with laws, regulations, internal standards, codes of conduct, and guidelines established for the business and activities of the organization.

The process of structuring new risk management is subdivided into five steps, according to the Corporate Risk Identification Manual. In December 2017, the CSGRC approved the framework for compliance risk management. The improvement of the management process will occur during the year 2018.

The Bank approved the Compliance Program, which aims at compliance risk

management, focusing on achieving compliance, sustainability and security in

business, processes, products and services, and enabling improvement in the

prevention of illegal acts, deviations from conduct and damage to reputation, resulting

in reduction of financial losses. It is based on the pillars Prevention, Detection and

Correction, with the following advisors:

a) support from the top management;

b) risk assessment;

c) Code of Ethics, Standards of Conduct and Compliance Policy;

d) training and communication;

e) regulatory monitoring;

f) due diligence;

g) internal controls;

h) complaint channels; and

i) internal investigations and consequence management.

7 Stress Test Program

The Basel Committee for Banking Supervision (CBSB)5 defined Stress Tests as an assessment of the Bank`s financial position under adverse or severe conditions, but plausible to occur. So the stress test model adopted by Banco do Brasil aims to test the resilience before the possibility of macroeconomic adverse or severe or idiosyncratic events occurrence.

So, BB works on stress test exercises considering:

a) Stress Tests per Category of Risk: stress tests used in the management of each risk, by considering their specificities;

a) Integrated Stress Tests (TEI): stress tests based on an only scenario of adverse or severe macroeconomic conditions or based an idiosyncratic scenario, depending on the case, applicable to risk variables in an integrated way, to business variables and their impacts on the results, on the Net Equity (PL) and on the Institution`s capital indicators.

For the exercise to accomplish its objective, the Bank uses assumptions that produce extreme situations, although plausible, capable of generating results in which solvency requirements are extrapolated.

It is important to mention that, for the accomplishment of TEI, the Bank uses corporate stress scenarios, which are approved by Board of Directors and define the intensity of different shocks.

The usage of the stress test as a management tool aims to provide the risks foward-looking assessment, aiming to evaluate the adherence to the Bank`s risk apetite level, subsidize the development of contingency plans and risk mitigation processes and support capital and liquidity planning processes.
