Risk Management |
| 42. | Risk Management:
| (1) | Introduction
The Bank's risk management is based on specialization, knowledge of the business and the experience of its teams, with professionals specifically dedicated to each different type of risks. Our policy is to maintain an integrated, forward looking approach to risk management, taking into account the current and forecasted economic environment and the risk/return ratio of all products for both the Bank and its subsidiaries. Our risk management policies are established in order to identify and analyze the risks faced by the Bank, set appropriate risk limits and controls, and to monitor the risks and compliance with the limits. Policies and risk management systems are reviewed regularly. Through its administration policies and procedures, the Bank develops a disciplined and constructive control environment.
| (a) | Risk Management Structure
Credit and Market Risk Management are at the all levels of the Organization, with a structure that recognizes the relevance of the different risk areas that exist. The current levels are:

The Board is responsible for approving the policies and establishing the structure for the proper administration of the various risks faced by the organization. The Board is permanently informed of the evolution of the different risk areas, participating through its Finance, International and Financial Risk, Credit, Portfolio Risk Committee and Higher Operational Risk Committee, in which the status of credit, market and operational risks are reviewed.
| (ii) | Finance, International and Financial Risk Committee

| (iii) | Credit Committees
The credit approval process is done mainly through various credit committees, which are composed of qualified professionals and with the necessary attributions to take decisions required. Each committee is responsible for defining the terms and conditions under which the Bank accepts counterparty risks and the Retail Credit Risk and Wholesale Credit Risk Divisions participate independently and autonomously of the commercial areas. They are constituted according to the commercial segments and the amounts to approve and have different meeting periodicities. Within the risk management structure of the Bank, the maximum approval instance is the Credit Committee of Directors. Sessions weekly and comprises of the Chairman of the Board, regular and alternate directors, Board Advisors, General Manager and the Wholesale Credit Risk Division Manager. This Committee is responsible for knowing, analyzing and resolving all credit operations associated with clients and / or economic groups whose total amount subject for approval is equal to or greater than UF 750,000. It also has to know, analyze and resolve all those credit operations that, in accordance with the established in the Bank's internal rules, must be approved by this Committee, with the exception of the special powers delegated by the Board to the Administration.

The Portfolio Risk Committee meets monthly and comprises of the Chairman of the Board, a regular and alternate Director, General Manager, Wholesale Credit Risk Division Manager, Retail Credit Risk Division Manager, Commercial Division Manager, Risk Management and Information Control Manager.
| (v) | Corporate Credit Risk Structure
The bank corporate governance considers the active participation of the Board, who establishes the policies and guidelines regarding the accepted risk levels, the Administration being responsible for the control and compliance with the provisions set forth by the Board, together with the setting of standards and procedures related. Likewise, the Board establishes the guidelines for the development and validation of models, approves the provisions models and pronounced about the sufficiency of provisions. At the administration level, the Retail Credit Risk, Wholesale Credit Risk and Global Risk Control divisions comprise the corporate risk governance structure, which through specialized teams, added to a robust regulatory framework of processes and procedures allow optimal management and effective in the subjects they address. The first two are responsible for the credit risk in the admission, monitoring and recovery phases, in the respective Retail and Wholesale segments. Along with this, in the Retail Credit Risk Division the different methodologies related to regulatory and management aspects are developed. The Wholesale Credit Risk Division, in turn, has a Market Risk Area responsible for measuring, limiting, controlling and reporting said risk along with the valuation standards definition. The Global Risk Control Division through the Operational and Technological Risk Areas, which incorporates Business Continuity, is responsible for controlling those risks, also has an Internal Validation Area of Risk Models. Additionally, the Bank has a Cybersecurity Division, focused on protecting and monitoring the most sensitive assets of the organization, being able to provide security and confidence to customers and collaborators, whose main objective is to have a secure bank, cyber-resilient and prepared to face any type of threat that puts the reputation and information of the organization at risk. These divisions have teams with extensive experience and knowledge in each area associated with credit and market risks, ensuring their integral and consolidated management, including the Bank and its subsidiaries.
| (b) | Measurement Methodology
Regarding to Credit Risk, provision levels and portfolio expenses are the basic measures for determining the credit quality of our portfolio. Banco de Chile permanently evaluates its loan portfolio, timely recognizing the associated level of risk of the loan portfolio. For this comprehensive credit risk assessment, there are policies, standards, procedures, along with models developed in accordance with the instructions issued by the Financial Market Commission ("CMF") and approved by the Board of Directors. As a result of this evaluation, on both individual and group portfolios, the level of provisions that the bank should constitute is determined, in the event of customers payment default. The individual evaluation mainly applies to the Bank's portfolio of legal persons that, due to their size, complexity or indebtedness, requires a more detailed level of knowledge and a case-by-case analysis. Each debtor individually assessed is assigned one of the 16 risk categories defined by the CMF, in order to establish the provisions in a timely and appropriate manner. This review of the portfolio risk classifications is carried out permanently considering the financial situation, payment behavior and the environment of each client. The group evaluation mainly applies to the portfolio of natural persons and smaller companies. These assessments are carried out monthly through statistical models that allow estimating the appropriate level of provisions necessary to cover the portfolio risk. The consistency of the models is analyzed through an independent validation of the unit that develops them and, subsequently, through the analysis of retrospective tests that allow to compare the real losses with the expected ones. The Bank annually performs a sufficiency test of provisions for the total portfolio of loans, in order to validate the quality and robustness of the risk assessment processes, verifying that the provisions constituted are sufficient to cover the losses that could be derive from the credit operations granted. The result of this analysis is presented to the Board of Directors, who declares on the sufficiency of the provisions in each year. Banco de Chile constitutes additional provisions with the objective of protecting itself from the risk of unpredictable economic fluctuations that may affect the macroeconomic environment or the situation of a specific economic sector. The amount of additional provisions to be constituted or released is annually proposed to the Portfolio Risk Committee and subsequently to the Board of Directors for approval. The monitoring and control of risks are carried out mainly based on limits established by the Board of Directors. These limits reflect the Bank's business and market strategy, as well as the level of risk that it is willing to accept, with additional emphasis on the selected industries. The Bank's General Manager receives on daily basis, and the Finance, International and Financial Risk Committee on a monthly basis, the evolution of the Bank's price and liquidity risk status, both according to internal metrics and those imposed by the regulators.
| (2) | Credit Risk
Credit risk considers the likelihood that the counterparty in the credit operation will not meet its contractual obligation due to incapacity or financial insolvency, and this leads to a potential credit loss. Credit risk management has a relevant focus on the adequate risk-return relation, is permanent and considers the processes of admission, monitoring and recovery of loans granted. In this management, an adequate balance of the risks assumed is taken into account, ensuring the solvency of the Bank over time. The established credit risk policies and processes recognize the singularities that exist in the different markets and segments, and grant a specialized treatment to each of them. The above results in the following management principles:
| 1. | Rigorous evaluation in the admission process applying the defined credit risk policies, their associated rules and procedures, together with the availability of sufficient and accurate information. This implies analyzing the generation of flows and solvency of the client to meet the payment commitments and, when the characteristics of the operation merit it, must constitute adequate collateral that allow mitigating the risk incurred with the client.
| 2. | Have permanent and robust portfolio tracking processes, through systems that alert both the potential signs of impairment in relation to the conditions of origin, as well as the possible business opportunities with those clients that present a better payments quality and behavior.
| 3. | To develop advanced modeling and data management tools that allow for efficient decision-making at different stages of the credit process.
| 4. | Have a collection structure with agile and efficient processes that allow carrying out procedures according to the different types of defaults presented by the clients.
| 5. | Maintain an efficient administration in work teams organization, tools and availability of information that allow an optimal credit risk management.
Credit Risk Divisions continuously manage risk knowledge in order to contribute to the business and anticipate threats that may affect the solvency and quality of the portfolio. Its mission is to establish the Credit Risk management framework for the different segments of the Bank, within the defined regulatory scope and at the risk established by the entity, through a portfolio vision that allows us to manage, resolve and control the process of approval of operations related to the different portfolios of the Bank, in an efficient and proactive manner.
| (a) | Retail Segment
Admission management in these segments is mainly carried out through an evaluation that uses scoring tools, accompanied by an adequate model of credit attributions, which are required to approve each operation. These evaluations take into account the level of indebtedness, payment capacity and the maximum acceptable exposure for the client. In these segments, the Bank has segregated functions, distributed in the following areas:
| − | Model Area, has the responsibility of constructing statistical models, establishing the variables and their respective weightings. These models are validated by the Model Validation Area and submitted to the Models Technical Committee before approval in the Portfolio Risk Committee or the Board of Directors, as appropriate.
| − | Area of Integration in Management is responsible for incorporating statistical models in credit evaluation processes, ensuring an adequate linkage of the decision.
| − | Admission Area performs the evaluation of operations and clients, with specialization by regions and segments, which favors their knowledge of clients and socio-economic background. It also maintains a framework of policies and standards that ensure the quality of the portfolio according to the desired risk, defining guidelines for the admission of clients that are released to commercial and risk areas through programs and continuous training.
| − | Model and Portfolio Tracking Area is responsible for evaluating and measuring the performance of the models and the behavior of the portfolios, the latter especially through the monitoring of the main indicators of aggregate portfolio and layers analysis, reported in management reports, generating relevant information for decision making in different defined instances. This Area also ensures proper execution of the strategy, meeting the objectives of risk quality and return.
| − | Collection Area performs a cross-collection management in the Bank and centralizes recovery management in retail segments through Socofin, Bank's subsidiary company, defining refinancing criteria and payment agreements with customers, along with the incorporation of robust tools for collection management.
| (b) | Wholesale Segment
Admission management in these segments is based on an individual evaluation of the client and if it belongs to a group of companies, the relationship of the rest of the group with the Bank is also considered. This individual and group evaluation, if applicable, considers, among others, the financial capacity with emphasis on equity solvency, generation capacity, exposure levels, industry variables, evaluation of partners and management and aspects of the operation such as financing, term, products and possible collaterals. This process is supported by a rating model that allows greater homogeneity in the evaluation of the client and his group. Additionally, for the evaluation of clients, there are specialized areas in some segments that, due to their nature, require expert knowledge, such as real estate, construction, agricultural, financial, and international, among others. The permanent monitoring of the portfolio is carried out in a centralized manner, based on information periodically updated by both the client and the industry. Monitoring of compliance with the special conditions established in the admission stage is carried out, such as controls of financial covenants, coverage of certain collaterals and restrictions imposed at the time of approval. Alerts are also generated through monitoring to ensure the correct classification of the individual portfolio. Additionally, within the Admission areas, joint tasks are carried out that allow monitoring the development of operations from their gestation to their recovery, in order to ensure that the portfolio's risks are well recognized in a timely manner. Upon detection of clients that show signs of impairment or default with any condition, the commercial area to which the client belongs together with the Wholesale Credit Risk Division, establish action plans to regularize said situation. In those cases where they present problems in the recovery of their credits, there is the area of Special Asset Management, belonging to the Wholesale Credit Risk Division, in charge of the collection management, establishing action plans and negotiations based on the particular characteristics of each client.
| (c) | Derivative Transactions
We produce own models which are used for credit risk management purposes, known as the pre-settlement exposure (PSE). Generally, the PSE is computed as follows: PSE = Maximum (CMTM + CEF * Notional, 0) CMTM: Current Mark-to-Market of the transaction Notional: Transaction notional amount CEF: Credit Exposure Factor, which reflects the peak exposure within the life of the transaction, under 95% of confidence level. The portfolio approach is taken into account when computing exposures of several transactions closed with one single counterpart. Credit mitigating conditions for derivative transactions have become popular in the local financial markets. There are financial institutions that have accepted early termination clauses, and netting is also possible with corporations when appropriate documentation under a regular Master Agreement is signed. Collateral agreements have been requested by certain banks for inter-banking transactions within other financial institutions, but its effective application under Chilean Law make advisable not to include it in the exposure measurement. Derivatives transactions closed with counterparts residing abroad (mostly global banks) are documented utilizing ISDA and CSA. Netting and cash collateral above a certain threshold level are the typical credit mitigations schemes in place for this kind of transactions. This metric is used for measuring, limiting, controlling and reporting credit exposures by counterparty.
| (d) | Portfolio Concentration:
The maximum exposure to credit risk, by client or counterparty, without taking into account guarantees or other credit enhancements as of December 31, 2018 and 2019 does not exceed 10% of the Bank's effective equity. The following tables show credit risk exposure per balance sheet item, including derivatives, detailed by both geographic region and industry sector as of December 31, 2018:

The Bank also uses mitigating tactics for credit risk on derivative transactions. To date, the following mitigating tactics are used:
| ● | Accelerating transactions and net payment using market values at the date of default of one of the parties.
| ● | Option for both parties to terminate early any transactions with a counterparty at a given date, using market values as of the respective date.
| ● | Margins established with time deposits by customers that close FX forwards with subsidiary Banchile Corredores de Bolsa S.A.
The value of the guarantees that the Bank maintains related to the loans individually classified as impaired as of December 31, 2018 and 2019 is Ch$85,721 million and Ch$100,133 million, respectively. The value of the guarantees that the Bank maintains related to non-impaired loans as of December 31, 2018 and 2019 is Ch$295,634 million and Ch$344,098 million, respectively.
| (f) | Credit Quality by Asset Class:
The Bank determines the credit quality of financial assets using internal credit ratings. The rating process is linked to the Bank's approval and monitoring processes and is carried out in accordance with risk categories established by current standards. Credit quality is continuously updated based on any favorable or unfavorable developments to customers or their environments, considering aspects such as commercial and payment behavior as well as financial information. The Bank also conducts reviews of companies in certain industry sectors that are affected by macroeconomic or sector-specific variables. Such reviews allow the Bank to timely establish any necessary allowance loan losses that are sufficient to cover losses for potentially uncollectable loans. Analysis of age of portfolio loan, over-due loans by financial asset class.

| (*) | These amounts include installments that are overdue, plus the remaining balance of principal and interest on such loans.
| (g) | Assets Received in Lieu of Payment:
The Bank has received assets in lieu of payment totaling Ch$24,871 million and Ch$18,737 as of December 31, 2018 and 2019, respectively, the majority of which are properties. All of these assets are managed for sale.
| (h) | Renegotiated Assets:
The impaired loans are considered to be renegotiated when the corresponding financial commitments are restructured and the Bank assesses the probability of recovery as sufficiently high. The following table details the book value of loans with renegotiated terms per financial asset class:
|  | 2018 |  |  | 2019 |

Total renegotiated financial assets |  |  | 569,671 |  |  |  | 598,375 |
The Bank calculates ECLs either on a group or an individual basis, which are described in more detail in Note 2(i)(vii). The renegotiated portfolio of Banco de Chile represents 1.99% of the total loans and the redefault rate of these loans for retail segment is 35.80% as of December 31, 2019 (the Bank does not have this information for other segments for internal purposes). The most common type of modification is to extend the term of the loan. For payment extensions, depending on the characteristics of each credit, the Bank may change the initial conditions in terms of interest rate and initial grace period for the first payment. With respect to forgiveness of principal, the Bank typically does not give this benefit. The Board of Directors might on rare occasions approve debt forgiveness for a portion of principal on certain credit-operations that have been impaired and provisioned previously. Only those borrowers which are considered viable are renegotiated, and that the average term of renegotiated retail credit segment is 57 months, demonstrating the relatively short payment extensions given. If the debtor is not considered to be financially viable, the Bank proceeds to the legal collection of debts. The table below includes Stage 2 and 3 assets that were modified and, therefore, treated as forborne during the 2019 period, with the related modification loss suffered by the Bank.
|  | 2019 MCh$ |
Amortized costs of financial assets modified during the period |  |  | 227,718 |
Net modification loss |  |  | 81,974 |
The Bank does not have information related to the balance of loans modified by type of concession because is not required to record this information by the local banking regulator and this information is much used by our peers. However, the Bank continually monitors its deteriorated portfolio as defined in Note 2(i) (vii). Also, for internal purposes the renegotiated loan portfolio is analyzed and reviewed as part of the impaired portfolio. Therefore, for management and regulatory (local and IFRS) reporting purposes the Bank does not frequently use information on loans modified by types of concession. The table below shows the gross carrying amount of previously modified financial assets for which loss allowances has changed to 12 month Expected Credit Losses (12mECL) measurement during the 2019 period:
|  | December 31, 2019 |
|  | Post modification |  |  | Pre-modification |
|  | Gross carrying amount MCh$ |  |  | Corresponding ECL MCh$ |  |  | Gross carrying amount MCh$ |  |  | Corresponding ECL MCh$ |
Facilities that have cured since modification and are now measured using 12mECLs (Stage 1) |  |  | 32,105 |  |  |  | 3,668 |  |  |  | 32,870 |  |  |  | 7,577 |
Facilities that reverted to (Stage 2/3) lifetime ECLs having once cured |  |  | 4,043 |  |  |  | 1,132 |  |  |  | 3,927 |  |  |  | 613 |
The Bank determines the appropriate amount of allowance for loan losses as follows: The commercial loan renegotiations are always evaluated and approved individually by the credit committee with all the background and history of previous approvals, including financial records, delinquencies or other previous renegotiations of the debtor. Since almost the entire commercial portfolio is individually provisioned, it is in this approval step of the renegotiation where the level of provision for each debtor is determined. Among the variables that are considered by the credit committee to establish the level of provisions is payment capacity and the collateral coverage. The condition of a new default of a renegotiated credit is considered when the credit committee is establishing the new level of provisions, which in general as a consequence of this higher risk, could increase up to 65% of the loan. On the other hand, for the portfolio evaluated for provisioning purposes as a group, the models contain past behavior variables, incorporating delinquencies and default prior to renegotiation for six months, recognizing the increased risk and generating a higher level of provisions. The provision can only be decreased if the renegotiated client has good payment behavior (an overdue period of less than 30 days), in a period of over seven months. Moreover, an operation identified as renegotiation never leaves this classification for purposes of monitoring and provisioning.
| (i) | Impairment Testing
The main tools used to test loan impairment include an analysis of whether principal or interest payments are more than 90 days past due or if the counterparty is experiencing any known cash flow problems, reductions in credit ratings or default of the original contractual terms.
| (j) | Off balance sheet accounts
In order to meet our customers' financial needs, the Bank has extended several irrevocable commitments and contingent obligations. Even though these obligations are not recognized in the balance sheet, they involve credit risk and thus form part of the Bank's general risk exposure. Credit risk exposure generated by contingent obligations is disclosed in Note No. 27.
| (3) | Market Risk:
Market Risk refers to the loss that the Bank could face due to a liquidity shortage to honor the payments or close financial transactions in a timely manner (Liquidity Risk), or due to adverse movements in the values of market variables (Risk Price).
| (a) | Liquidity Risk
Liquidity Risk Measurement and Limits The Bank manages the Liquidity Risk separately for each sub-category: Trading Liquidity Risk and Funding Liquidity Risk. Trading Liquidity Risk is the inability to close, at current market prices, the financial positions opened mainly from the Trading Book (which is daily valued at market prices and the value differences instantly reflected in the Income Statement). This risk is controlled by establishing limits on the positions amounts of the Trading Book in accordance with what is estimated to be closed in a short time period. Additionally, the Bank incorporates a negative impact on the Income Statement whenever it considers that the size of a certain position in the Trading Book exceeds the reasonable amount, negotiated in the secondary markets, which would allow the exposure to be offset without altering market prices. Funding Liquidity Risk refers to the Bank's inability to obtain sufficient cash to meet its immediate obligations. This risk is managed by a minimum amount of highly liquid assets called liquidity buffer, and establishing limits and controls of internal metrics, among which the Market Access Report ("MAR") stands out, which estimates the amount of funding that the Bank would need from wholesale financial counterparties, for the next 30 and 90 days in each of the relevant currencies of the balance sheet, to face a cash need as a result of the operation under business as usual conditions, that is, basically, rollover of the total loans portfolio, the output of a volatile part of the demand deposits accounts and of the retailers term deposits, and the expiration of all the wholesalers term deposits. The use of MAR within year 2019 is illustrated below (LCCY = local currency; FCCY = foreign currency):
|  |  | MAR LCCY + FCCY MMM$ |  |  | MAR FCCY MMUS$ |
|  |  | 1 – 30 days |  |  | 1 – 90 days |  |  | 1 – 30 days |  |  | 1 – 90 days |
Maximum |  |  |  | 3,352 |  |  |  | 5,498 |  |  |  | 1,999 |  |  |  | 3,254 |
Minimum |  |  |  | 1,705 |  |  |  | 3,993 |  |  |  | 1 |  |  |  | 1,407 |
Average |  |  |  | 2,621 |  |  |  | 4,841 |  |  |  | 1,052 |  |  |  | 2,479 |
The Bank also monitors the amount of assets denominated in local currency that is funded by liabilities denominated in foreign currency, including all tenors and the cash flows generated by derivatives payments to be made in foreign currency in the future. This metric is referred to as Cross Currency Funding. The Bank oversees and limits this amount in order to take precautions against not only Banco de Chile's event but also against a systemic adverse environment generated by a country risk event that might trigger lack of foreign currency funding. The use of Cross Currency Funding within year 2019 is illustrated below:
|  |  | Cross Currency Funding MMUS$ |
Maximum |  |  |  | 3,339 |
Minimum |  |  |  | 1,742 |
Average |  |  |  | 2,640 |
Additionally, the Bank establishes thresholds that alert behaviors outside the expected ranges at a normal or prudent level of operation, in order to protect other dimensions of liquidity risk such as the maturities concentration of fund providers and the diversification of sources of funds either by type of counterparty or type of product, among others. Likewise, the evolution over time of the Bank's financial ratios that can detect structural changes in its balance sheet characteristics is monitored, such as those presented in the following table and whose relevant use values during the year 2019 are shown below:
|  |  | Liquid Assets/ Net Funding <30 days |  |  | Liabilities>1 year/ Assets >1 year |  |  | Deposits/ Loans |
Maximum |  |  |  | 103 | % |  |  | 82 | % |  |  | 62 | %
Minimum |  |  |  | 82 | % |  |  | 76 | % |  |  | 58 | %
Average |  |  |  | 92 | % |  |  | 78 | % |  |  | 60 | %
Moreover, some market index, prices and monetary decisions taken by the Central Bank of Chile are monitored to detect structural changes in market conditions that can trigger a liquidity shortage or even a financial crisis. The Bank measures and controls the mismatch of cash flows under regulatory standards with the C46 index report, which represents the net cash flows expected over time as a result of the contractual maturity of almost all assets and liabilities. Additionally, the Commission for the Financial Market (hereinafter, "CMF") authorized Banco de Chile, among others, to report the adjusted C46 index. This allows the Bank to report, in addition to the regular C46 index, outflow behavior assumptions of certain specific elements of the liability, such as demand deposits and time deposits. In addition, the regulator also requires some rollover assumptions for the loan portfolio. The CMF establish the following limits for the C46: Foreign Currency balance sheet items: 1-30 days C46 index < 1 x Tier-1 Capital All Currencies balance sheet items: 1-30 days C46 index < 1 x Tier-1 Capital All Currencies balance sheet items: 1-90 days C46 index < 2 x Tier-1 Capital The use of this index in year 2019 is illustrated below:
|  | Adjusted C46 All CCYs as part of Tier-1 Capital |  |  | Adjusted C46 FCCY as part of Tier-1 Capital |
|  |  | 1 – 30 days |  |  |  | 1 – 90 days |  |  |  | 1 – 30 days |
Maximum |  |  | 0.56 |  |  |  | 0.79 |  |  |  | 0.42 |
Minimum |  |  | 0.32 |  |  |  | 0.55 |  |  |  | 0.15 |
Average |  |  | 0.49 |  |  |  | 0.69 |  |  |  | 0.28 |
Regulatory Limit |  |  | 1.0 |  |  |  | 2.0 |  |  |  | 1.0 |
Additionally, the regulatory entities have introduced other metrics that the Bank uses in its management, such as the Liquidity Coverage Ratio ("LCR") and Net Stable Funding Ratio ("NSFR"), using assumptions similar to those used in the international banking. Only for the first one, a limit implementation calendar has been established and that during the year 2019 was with a minimum level of 60%. The evolution of the LCR and NSFR metrics during the year 2019 are shown below:
|  | LCR |  |  | NSFR |
Maximum |  |  | 1.17 |  |  |  | 1.02 |
Minimum |  |  | 0.88 |  |  |  | 0.97 |
Average |  |  | 0.99 |  |  |  | 0.99 |
Regulatory Limit |  |  | 0.6 | (*) |  |  | N/A |
| (*) | This is the current minimum value for the year 2019 and that increases 0.1 annually until reaching 1.0 in the year 2023.

| (b) | Price Risk:
Price Risk Measurement and Limits The measurement and management of Price Risk are carried out through the use of several metrics developed internally by the Bank, both for the Trading Book and for the Accrual Book (the Accrual Book includes all balance sheet items, even those of the Trading book but in such case these are reported at an interest rate adjustment period of one day, thus not generating accrual interest rate risk). In addition, the Bank reports metrics to regulatory entities according to the models defined by them. The bank has established internal limits for the exposures of the Trading Book. In fact, FX positions (FX delta), Equity positions (Equity delta), interest rate sensitivities generated by the derivatives and debt securities portfolios (DV01 or also referred as to rho) and the FX volatility sensitivity (vega) are measured, reported and against their limits. Limits are established on an aggregate basis but also for some specific tenor points. The use of these limits is daily monitored, controlled and reported by independent control functions to the senior management of the bank. The internal governance framework also establishes that these limits must be approved by the board and reviewed at least annually. The Bank measures and controls the risk for the Trading Book portfolios using the Value-at-Risk (VaR). The model uses a 99% confidence level and the most recent one-year observed rates, prices and yields data. The use of VaR within year 2019 is illustrated below:
|  | Value-at-Risk |
|  | 99% one-day confidence level MMUS$ |
Maximum |  |  | 872 |
Minimum |  |  | 176 |
Average |  |  | 562 |
Additionally, the Bank performs measuring, limiting, controlling and reporting interest rate exposures and risks for the Accrual Book using internally developed methodologies based on the differences in the amounts of assets and liabilities considering the interest rate repricing dates. Exposures are measured according to the Interest Rate Exposure or IRE metric and their corresponding risks using to the Earnings-at-Risk or EaR metric. The use of EaR within year 2019 is illustrated below:
|  |  | 12-months Earnings-at-Risk |
|  |  | 99% confidence level 3 months defeasance period MCh$ |
Maximum |  |  |  | 54,372 |
Minimum |  |  |  | 45,023 |
Average |  |  |  | 47,743 |
The regulatory risk measurement for the Trading portfolio (C41 report) is produced by utilizing guidelines provided by the regulatory entities (Central Bank of Chile and Commission for the Financial Market, hereafter "CBCh" and "CMF" respectively), which are adopted based on standardized BIS methodologies. The referred methodologies estimate the potential loss that the bank may incur considering standardized fluctuations of the value of market factors such as FX rates, interest rates and volatilities that may adversely impact the value of FX spot positions, interest rate exposures, and volatility exposures, respectively. In addition, correlation factors are included to represent non-parallel changes in the yield curve. The CMF does not set an individual limit for this particular risk, but a global one that includes this risk (also called Market Risk Equivalent or MRE) and the Credit Risk Weighted Assets. The risk measurement for the Banking Book, according to normative guidelines (C40 report), as a result of interest rate fluctuations is carried out through the use of standardized methodologies provided by regulatory entities (BCCh and CMF). The report includes models for reporting interest rate gaps and standardized adverse interest rate fluctuations. In addition to this, the regulatory entity has requested banks to establish internal limits for this regulatory risk measurement. Limits must be established separately for short-term and long-term balance. The short-term risk limit should be expressed as a percentage of the Net Interest Margin or NIM plus the revenue collected from commissions that depend on the level of the interest rate; the long-term risk limit cannot exceed a specific percentage of the amount of effective equity. In addition to the above, the Market Risk Policy of Banco de Chile enforces to perform daily stress tests for the Trading Book and monthly for the Accrual Book. The output of the stress testing process is monitored against corresponding trigger levels: in the case those triggers are breached, the senior management is notified in order to implement further actions, if necessary. In addition, the results during the month for the trading activities are controlled against defined loss levels and in case such levels are exceeded, senior management is also notified. The following table illustrates the interest rate cash-flows of the Banking Book, considering the interest rate repricing dates on an individual basis, as of December 31, 2018 and 2019:

Price Risk Sensitivity Analysis The Bank uses stress tests as the main sensitivity analysis tool for Price Risk. The analysis is implemented for the Trading Book and the Accrual Book separately. The Bank has adopted this tool as it is considered more useful than fluctuations in business as usual scenario, such as VaR or EaR, given that:
| (i) | The financial crisis show market factors fluctuations that are materially larger than those used in the VaR with 99% of confidence level or EaR with 99% of confidence level.
| (ii) | The financial crisis also show that correlations between these fluctuations are materially different from those used in the VaR computation, since a crisis precisely indicates severe disconnections between the behaviors of market factors fluctuations respect to the patterns observed under normal conditions.
| (iii) | Trading liquidity dramatically diminishes during financial distress and especially in emerging markets. Therefore, the overnight VaR number might not be representative of the loss for trading portfolios in such environment since closing exposures period may exceed one business day. This may also happen when calculating EaR, even considering three months as the closing period.
The impacts are determined by mathematical simulations of fluctuations in the values of market factors, and also, estimating the changes of the economic and / or accounting value of the financial positions. In order to comply with IFRS 7.40, the following exercise was included illustrating an estimation of the impact of extreme but reasonable fluctuations of interest rates, swaps yields, FX rates and exchange volatility, which are used for valuing Trading and Accrual portfolios. Given that the Bank's portfolio includes positions denominated in nominal and real interest rates, these fluctuations must be aligned with extreme but realistic Chilean inflation changes forecasts. The exercise is implemented in a simple way: Trading portfolios impacts are estimated by multiplying the sensitivities by the fluctuations obtained as the results of mathematical simulations over a two-week time horizon and using the maximum historical volatility of the last fifteen years in each of the market factors; Accrual portfolios impacts are estimated by multiplying cumulative gaps by forward interest rates fluctuations modeled over a three-month time horizon and using the maximum historical volatility of interest fluctuations but limited by maximum fluctuations and / or levels observed during the last fifteen years. It is relevant to note that the methodology might ignore some portion of the interest rates convexity, since it is not captured properly when large fluctuations are modeled. In any case, given the magnitude of the changes, the methodology may be reasonable enough for the purposes and scope of the analysis. The following table illustrates the fluctuations resulting from the main market factors in the maximum stress test exercise, or more adverse, for the Trading Book. The directions or signs of these fluctuations are those that correspond to those that generate the most adverse impact at the aggregate level.
Average Fluctuations of Market Factors for Maximum Stress Scenario Trading Book
|  | CLP Derivatives (bps) |  |  | CLP Bonds (bps) |  |  | CLF Derivatives (bps) |  |  | CLF Bonds (bps) |  |  | USD Offshore Libor Derivatives (bps) |  |  | Spread USD On/Off Derivatives (bps) |
Less than 1 year |  |  | 103 |  |  |  | 47 |  |  |  | 163 |  |  |  | 108 |  |  |  | -62 |  |  |  | -9 |

bps = basis points The worst impact on the Bank's Trading Book as of December 31, 2019, as a result of the simulation process described above, is as follows:
Most Adverse Stress Scenario P&L Impact Trading Book (MCh$)
CLP Interest Rate |  |  |  |  |  |  | (4,968 | )
Derivatives |  |  | (3,006 | ) |  |  |  |
Debt instruments |  |  | (1,962 | ) |  |  |  |
CLF Interest Rate |  |  |  |  |  |  | (8,694 | )
Derivatives |  |  | (2,600 | ) |  |  |  |
Debt instruments |  |  | (6,094 | ) |  |  |  |
Interest rate USD offshore |  |  |  |  |  |  | (1,963 | )
Domestic/offshore interest rate spread USD |  |  |  |  |  |  | (50 | )
Total Interest rates |  |  |  |  |  |  | (15,675 | )
Total FX |  |  |  |  |  |  | (16 | )
Total FX Options |  |  |  |  |  |  | 224 |
Total |  |  |  |  |  |  | (15,467 | )
The modeled scenario would generate losses in the Trading Book for approximately MCh$15,500. In any case, such fluctuations would not result in material losses compared to Basic Capital (Tier-1) or to the P&L estimate for the next 12-months. The impact on the Accrual Book for the next 12 months as of December 31, 2019, which does not necessarily mean a net loss / gain but a greater/lower net income from funds generation (resulting net interest rate generation), is illustrated below:
Most Adverse Stress Scenario 12-Month Revenue Accrual Book (MCh$)
Impact by Base Interest Rate shocks |  |  | (164,322 | )
Impact due to Spreads Shocks |  |  | (67 | )
Higher / (Lower) Net revenues |  |  | (164,389 | )
The main negative impact on the Trading Book would occur as a result of a drastic increase in local interest rates. The lowest potential income in the next 12 months in the Accrual Book would occur in a scenario of sharp fall in inflation. In any case, the impacts would be less than the annual budgeted profits of the Bank.
| (4) | Capital Requirements and Capital Management:
The main objectives of the Bank's capital management are to ensure compliance with regulatory requirements, maintain a solid credit rating and sound capital ratios. During 2019, the Bank has successfully met the required capital requirements. As part of its Capital Management Policy, the Bank has established capital adequacy alerts, which are stricter than those required by the regulator, which are monitored on a monthly basis. During 2019, none of the internal alerts defined in the Capital Management Policy were activated. The Bank manages capital by making adjustments in light of changes in economic conditions and the risk characteristics of its business. For this purpose, the Bank may modify the amount of dividend payments to its shareholders or issue equity instruments. The capital adequacy of the Bank is monitored using, among other measures, the indexes and rules established by the CMF. Regulatory Capital According to the Chilean General Banking Law, Banks must maintain a minimum ratio of 8%, net of required provisions, as a result of dividing the Equity by the sum of the Consolidated Weighted Assets by Risk. In addition, banks must maintain a minimum ratio of Basic Capital to Total Consolidated Assets of 3%, net of required provisions. As a result of the merger of Banco de Chile with Citibank Chile in 2008, the CMF established that the institution was obliged to maintain the first reason Less than 10%. In this way, the regulatory body ratified the validity of the minimum of 10% that it had already set in December 2001 by authorizing the merger by absorption of Banco Edwards into Banco de Chile. Equity is determined from Capital and Reserves or Basic Capital with the following adjustments: (a) the balance of subordinated bonds issued with a maximum equivalent to 50% of the Basic Capital is added and weighted according to their term at maturity; (b) the additional provisions for loans are added, (c) the balance of the assets corresponding to goodwill or overpaid and investments in companies not included in the consolidation is deducted, and (d) the balance of noncontrolling interest is added. Assets are weighted according to the risk categories, which are assigned a risk percentage that would reflect the amount of capital needed to support each of those assets. There are 5 risk categories (0%, 10%, 20%, 60% and 100%). For example, cash, deposits in other banks and financial instruments issued by the Central Bank of Chile have 0% risk, which means that, according to current standards, no capital is required to back these assets. Properties and equipment have a 100% risk, which means that they must have a minimum capital equivalent to 8% of the amount of these assets and in the case of the Bank of Chile 10%. All derivative instruments traded outside of stock exchanges are considered in the determination of risk assets with a conversion factor over the notional values, thus obtaining the amount of exposure to credit risk (or "credit equivalent"). The contingent credits out of balance are also considered by a "credit equivalent", for their weighting. The risk-weighted assets and TIER 1 and TIER 2 Capital, as of December 31, 2019 and 2018 are the following:
|  | Consolidated assets |  |  | Risk-weighted assets |
|  | 2018 |  |  | 2019 |  |  | 2018 |  |  | 2019 |
