NOTE 39

RISK MANAGEMENT

Introduction and general description

The Bank, due to its activities with financial instruments is exposed to several types of risks. The main risks related to financial instruments that apply to the Bank are as follows:

Market risk: rises from holding financial instruments whose value may be affected by fluctuations in market conditions, generally including the following types of risk:

Foreign exchange risk: this arises as a consequence of exchange rate fluctuations among currencies,

Interest rate risk: this arises as a consequence of fluctuations in market interest rates,

Price risk: this arises as a consequence of changes in market prices, either due to factors specific to the instrument itself or due to factors that affect all the instruments negotiated in the market,

Inflation risk: this arises as a consequence of changes in Chile’s inflation rate, whose effect would be mainly applicable to financial instruments denominated in UFs,

Credit risk: this is the risk that one of the parties to a financial instrument fails to meet its contractual obligations for reasons of insolvency or inability of the individuals or legal entities in question to continue as a going concern, causing a financial loss to the other party.

Liquidity risk: is the possibility that an entity may be unable to meet its payment commitments, or that in order to meet them, it may have to raise funds with onerous terms or risk damage to its image and reputation.

Capital risk: this is the risk that the Bank may have an insufficient amount and/or quality of capital to meet the minimum regulatory requirement to operate as a bank, respond to market expectations regarding its creditworthiness, and support its business growth and any strategic possibilities that might arise, in accordance with its strategic plan.

This note includes information on the Bank’s exposure to these risks and on its objectives, policies, and processes involved in their measurement and management.

Risk management structure

The Board is responsible for the establishment and monitoring of the Bank’s risk management structure, for which purpose it has an on-line corporate governance system which incorporates international recommendations and trends, adapted to Chilean regulatory conditions and given it the ability to apply the most advanced practices in the markets in which the Bank operates.

The effectiveness with which we are able to manage the balance between risk and reward is a significant factor in our ability to generate long term, stable earnings growth, Toward that end, our Board and senior management places great emphasis on risk management.

A. Integral Risk Committee

The Integral Risk Committee of the Board is responsible for reviewing and monitoring all risks that may affect us, including reputation risk, allowing for an integral risk management. This committee serves as the governing body through which the Board supervises risk in general, It also evaluates the reasonability of the systems for measurement and control of risks.

●

Credit risk

●

Market risk

●

Operational risk

●

Solvency risk (BIS)

●

Legal risks

●

Compliance risks

●

Reputational risks

This Committee includes the Vice Chairman of the Board and five Board members. This committee also includes the CEO, the Director of Risk and other senior level executives from the commercial side of our business.

B. Audit Committee

The Audit Committee (Comité de Directores y Auditoría) is comprised of three members of the Board of Directors. The Chief Executive Officer, General Auditor and other persons from the Bank can be invited to the meetings if necessary and are present on specific matters. This Committee’s primary responsibility is to support the Board of Directors in the continuous improvement of our system of internal controls, which includes reviewing the work of both the external auditors and the Internal Audit Department. The committee is also responsible for analyzing observations made by regulatory entities of the Chilean financial system about us and for recommending measures to be taken by our management in response. This committee also performs functions of a remuneration committee as established in Chilean Law, and reviews annually the salary and bonus programs for the executive officers of the Bank. The external auditors are recommended by this committee to our Board of Directors and appointed by our shareholders at the annual shareholders’ meeting.

C. Asset and Liability Committee

The ALCO includes the Chairman of the Board and five additional members of the Board, the Chief Executive Officer, the Corporate Financial Controller, the Manager of the Financial Management Division, the Manager of Market Risk, the Manager of the Treasury Division, and other senior members of management. The ALCO meets monthly. All limits reviewed by the ALCO are measured and prepared by the Market Risk Department. The non-Board members of the ALCO meet weekly to review liquidity, funding, capital and market risk related matters.

The main functions of the ALCO are:

●

Making the most important decisions regarding our exposure to inflation, interest rate risk, funding, capital and liquidity levels, The main limits set and monitored by the ALCO (and measured by the Market Risk Department) are:

●

Review of the Bank’s inflation gap

●

Review of the evolution of the most relevant local and international markets and monetary policies

D. Market Committee

The Market Committee includes the Vice-Chairman of the Board, three additional members of the Board, the Chief Executive Officer, the Manager of Global Banking and Markets, the Manager of the Treasury Division, the Manager of the Financial Management Division, the Manager of Market Risk, the Financial Controller and other senior members of management.

The Market Committee is responsible for:

●

Establishing a strategy for the Bank’s trading investment portfolio

●

Establishing the Bank’s policies, procedures and limits with respect to its trading portfolio, The Bank’s Market Risk Department measures all risks and limits and reports these to the Market Committee

●

Reviewing the net foreign exchange exposure and limit

●

Reviewing the evolution of the most relevant local and international markets and monetary policies

E. Risk Department

All issues regarding risk in the Bank are the responsibility of the Bank’s Risk Department. The Risk Department reports to the CEO but has full independence, and no risk decisions can be made without its approval.

Credit risk

Credit risk is the risk that one of the parties to a financial instrument fails to meet its contractual obligations for reasons of insolvency or inability of the individuals or legal entities in question to continue as a going concern, causing a financial loss to the other party. The Bank consolidates all elements and components of credit risk exposure to manage credit risk (e,g, individual delinquency risk, inherent risk of a business line or segment, and/or geographical risk).

In Note 9 and Note 11, we present our net exposure to credit risk at December 31, 2018 and 2017.

Credit Risk Governance

The Risk Division, our credit analysis and risk management group, is largely independent of our Commercial Division. Risk evaluation teams interact regularly with our clients. For larger transactions, risk teams in our headquarters work directly with clients when evaluating credit risks and preparing credit applications. Various credit approval committees, all of which include Risk Division and Commercial Division personnel, must verify that the appropriate qualitative and quantitative parameters are met by each applicant. Each committee’s powers are defined by our Board of Directors.

Santander-Chile’s governance rules have established the existence of the Integral Risk Committee. This committee is responsible for revising and following all risks that may affect us, including reputational risk, allowing for an integral risk management. This committee serves as the governing body through which the Board supervises all risk functions. It also evaluates the reasonability of the systems for measurement and control of risks. This Committee includes the Vice Chairman of the Board and five Board members.

The Board has delegated the duty of credit risk management to the Integral Risk Committee, as well as to the Bank’s risk departments, whose roles are summarized below:

●

Verify compliance with the strategic objectives of the group, depending on both assumed and potential risk, and alerting management to such risks.

●

Propose the primary metrics for risk appetite framework.

●

Review the level of compliance with regulatory provisions and recommendations issued by the Local and External Supervisors, ensuring their implementation on the stipulated dates.

●

Analyze with a comprehensive vision, the map of recommendations and incidents formulated by the different control instances (SBIF, DAI and External Audit) in order to identify the main risks involved.

●

Review the risk benchmark analysis, and from its results, identify and propose “best practices” or corrective / preventive actions, ensuring their proper implementation.

●

Review the adequate management of risks by the management areas, formulating where appropriate, the mitigation actions in accordance with the policies approved by the Board.

●

Monitoring, analysis and control of the limits defined in the Risk Framework (basic and complementary metrics) and the key credit risk indicators of each zone, segment or product, identifying possible sources of concern.

●

Analyze the relevant aspects of the risk (exogenous variables), which could eventually materialize in possible losses for the business (emerging risks).

●

Analyze and propose eventual changes in the policies and procedures used by the Bank for the administration, control and management of risks, when inconsistencies or vulnerabilities are verified.

●

Encourage compliance by the Bank with the best corporate governance practices in risk management. Pre-review the documents of type 0 and 1 (Frames and Models) that were defined in the Approval Hierarchy model, which must then be approved in the Directory.

●

Perform, according to the calendar proposed by the Risk Department or on request, the sectoral analyzes considered relevant.

●

Review of risks in terms of Risk Compliance and Reputational Risk

●

Any other task that the Board deems necessary.

The following diagram illustrates the governance of our credit risk division including the committees with approval power:

Role of Santander Spain’s Global Risk Department: Credit Risk

In matters regarding Credit Risk, Santander Spain’s Global Risk Department has the following role:

●

All credit risks greater than U.S.$40 million (U.S.$60 million for financial institutions), after being approved locally, are reviewed by Santander Spain. This additional review ensures that no global exposure limit is being breached.

●

In standardized risks, the consumer and mortgage scoring models are developed locally but are reviewed and approved by Santander Spain’s Global Risk Department.

●

For each scoring model, a monthly Risk Report is prepared, which is reviewed locally and is also sent to Santander Spain’s Global Risk Department. This report includes the evolution of basic credit risk parameters such as loan amounts, non-performance, charge-offs and provisions.

●

Monthly, the Controller of the Risk Department sends a report to Santander Spain’s Global Risk Department covering all the main indicators regarding credit risk and the evolution of credit risk as compared to the budgeted levels.

Impaiment assessment (policy applicable from January 1, 2018)

In accordance with the requirements of IFRS 9 the Bank has developed a new credit risk model, applicable from January 1, 2018.

Definition of default and cure

The Bank considers a financial instrument defaulted and therefore Stage 3 for ECL calculations in all cases when the borrower becomes 90 days past due on its contractual payments.

As a part of a qualitative assessment of whether a customer is in default, the Bank also considers a variety of instances that may indicate unlikeliness to pay. Such events include:

●

Internal rating of the borrower indicating default or near-default

●

The borrower requesting emergency funding from the Bank

●

The borrower having past due liabilities to public creditors or employees

●

The borrower is deceased

●

A material decrease in the underlying collateral value where the recovery of the loan is expected from the sale of the collateral

●

A material decrease in the borrower’s turnover or the loss of a major customer

●

A covenant breach not waived by the Bank

●

The debtor (or any legal entity within the debtor’s group) filing for bankruptcy application/protection

●

Debtor’s listed debt or equity suspended at the primary exchange because of rumours or facts about financial difficulties

It is the Bank’s policy to consider a financial instrument as ‘cured’ and therefore re-classified out of Stage 3 when none of the default criteria have been present for at least twelve consecutive months (and 24 months for special vigilance operations). The decision whether to classify an asset as Stage 2 or Stage 1 once cured depends on the updated credit grade, at the time of the cure, and whether this indicates there has been a significant increase in credit risk compared to initial recognition.

Internal rating and PD estimation

The Bank’s Credit Risk Department operates its internal rating models. The models incorporate both qualitative and quantitative information and, in addition to information specific to the borrower utilise supplemental external information that could affect the borrower’s behaviour. The internal credit grades are assigned based on the internal scoring policy. PDs are then adjusted for IFRS 9 ECL calculations to incorporate forward looking information and the IFRS 9 Stage classification of the exposure.

The following table shows quality assets and its related provision, based on our internal scoring policy as of December 31, 2018:

In relation to the credit quality of the investment portfolio, local regulations specify that banks are able to hold only local and foreign fixed–income securities except in certain cases, Additionally, Banco Santander Chile has internal policies to ensure that only securities approved by the Market Risk department, which are stated in the documents “APS” – Products and underlying Approval, are acquired, The Credit Risk Department sets the exposure limits to those approved APS’s , The APS is updated on daily basis.

As of December 31, 2018, 99% our total investment portfolio correspond to securities issued by the Chilean Central Bank and US treasury notes.

Exposure at default

The exposure at default (EAD) represents the gross carrying amount of the financial instruments subject to the impairment calculation, addressing both the client’s ability to increase its exposure while approaching default and potential early repayments too.

To calculate the EAD for a Stage 1 loan, the Bank assesses the possible default events within 12 months for the calculation of the 12mECL. However, if a Stage 1 loan that is expected to default in the 12 months from the balance sheet date and is also expected to cure and subsequently default again, then all linked default events are taken into account. For Stage 2, Stage 3 the exposure at default is considered for events over the lifetime of the instruments.

Loss given default

The credit risk assessment is based on a standardised LGD assessment framework that results in a certain LGD rate. These LGD rates take into account the expected EAD in comparison to the amount expected to be recovered or realised from any collateral held.

The Bank segments its retail lending products into smaller homogeneous portfolios (evaluated collective), based on key characteristics that are relevant to the estimation of future cash flows. The applied data is based on historically collected loss data and involves a wider set of transaction characteristics (e.g., product type, wider range of collateral types) as well as borrower characteristics.

Further recent data and forward-looking economic scenarios are used in order to determine the IFRS 9 LGD rate for each group of financial instruments. Under IFRS 9, LGD rates are estimated for the Stage 1, Stage 2, Stage 3 IFRS 9 segment of each asset class. The inputs for these LGD rates are estimated and, where possible, calibrated through back testing against recent recoveries. These are repeated for each economic scenario as appropriate.

Significant increase in credit risk (SICR)

The Bank continuously monitors all assets subject to ECLs. In order to determine whether an instrument or a portfolio of instruments is subject to 12 month ECL or Lifetime ECL, the Bank assesses whether there has been a significant increase in credit risk since initial recognition.

The Bank also applies a secondary qualitative method for triggering a significant increase in credit risk for an asset, such as moving a customer/facility to the watch list (Special vigilance). The Bank may also consider that events explained in letter a) above are a significant increase in credit risk as opposed to a default. Regardless of the change in credit grades, if contractual payments are more than 30 days past due, the credit risk is deemed to have increased significantly since initial recognition.

When estimating ECLs on a collective basis for a group of similar assets, the Bank applies the same principles for assessing whether there has been a significant increase in credit risk since initial recognition.

Quantitative criteria for SICR Stage 2:

The quantitative criteria is used to identify where an exposure has increased in credit risk and it is applied based on whether an increase in the lifetime PD since the recognition date exceeds the threshold set in absolute terms. The following formula is used to determine such threshold:

Threshold = Lifetime PD (at reporting date) – Lifetime PD (at origination)

There is also a relative threshold of 100% of all portfolios with the exception of the Corporate and Investment Banking Portfolio.

Qualitative criteria for SICR Stage 2:

The qualitative criteria is based on the existence of evidence that leads to an automatic classification of financial instruments in stage 2, mainly 30 days overdue and restructured. Thresholds of SICR are calibrated based on the average ECL of exposures that are 30 days overdue or with a level of credit risk considered to be “significant”.

These thresholds are defined by the Model Committee and the Integral Risk Committee, and are evaluated annually with updates made depending on impacts and definitions of the risk models associated to each portfolio.

Grouping financial assets measured on a collective basis

The Bank calculates ECLs either on a collective or an individual basis.

The evaluates on individual basis commercial loans that are greater than Ch$400 million (US$240,000), while smaller commercial loans, mortgage loans and consumer loans are grouped into homogeneous portfolios, based on a combination of internal and external characteristics.

Modified loans

When loan measured at amortised cost has been renegotiated or modified but not derecognised, the Bank must recognise the resulting gains or losses as the difference between the carrying amount of the original loans, and modified contractual cash flows discounted using the EIR before modification.

If the modification does not result in derecognition, then the subsequent assessment of whether there is a significant increase in credit risk is made comparing the risk at the reporting date based on the modified contractual term and the risk at initial recognition based on the original, unmodified contractual term.

If the modification results in dereconition, then the modified asset is considered to be a new asset. Accordingly, the date of modification is treated as the date of initial recogition for the purposes of the impairment requerments.

Macro economical forward looking information and scenarios

The annual growth forecasts for the most relevant macroeconomic variables for each of our scenarios are as follows:

	Average estimates 2019 - 2020
	Unfavorable scenario 2	Unfavorable scenario 1	Base scenario	Favorable scenario 1	Favorable scenario 2
Official interest rate	1.78%	2.82%	3.91%	4.99%	6.03%
Unemployment rate	8.47%	7.53%	6.55%	6.10%	5.57%
Housing Price growth	0.89%	1.06%	1.50%	2.68%	4.49%
GDP growth	1.40%	2.22%	2.99%	3.87%	4.68%
Consumer Price Index	1.14%	1.98%	2.83%	3.75%	4.59%

The highest probability of occurrence is associated to the base scenario, while the extreme scenarios have a lower probability than the more moderate scenarios.

The methodology used for the generation of the local scenarios is based on the Methodology Framework of the Corporate Research Service and is applied to the loan portfolio with the exception of loans from the Corporate and Investment Banking segment which uses global scenarios as defined by the Santander Group. The probabilities for the scenarios must total 100% and be symmetrical.

Local scenario		Global scenario
	Probability weighting		Probability weighting
Favorable scenario 2	5%	Favorable scenario 1	20%
Favorable scenario 1	20%	Base scenario	60%

Collateral and other credit enhancement

The amount and type of collateral required depends on an assessment of the credit risk of the counterparty. Guidelines are in place covering the acceptability and valuation of each type of collateral.

The main types of collateral obtained are, as follows:

●

For securities lending and reverse repurchase transactions, cash or securities

●

For corporate and small business lending, charges over real estate properties, inventory and trade receivables and, in special circumstances, government guarantees

●

For retail lending, mortgages over residential properties

The following table show the maximum exposure to credit risk by class of financial asset, associated collateral and the net exposure to credit risk:

According to the Bank’s policy when an asset (real state) is repossessed are transferred to aseets held for sale at their fair value less cost to sell as non-financial assets at the repossession date.

Impaiment assessment (under IAS 39)

Loans analyzed on an individual basis

For loans that are greater than Ch$400 million (US$570,000), the Bank uses internal models to assign a risk category level to each borrower and its respective loans. We consider the following risk factors: industry or sector of the borrower, the borrower’s competitive position in its markets, owners or managers of the borrower, the borrower’s financial situation, the borrower’s payment capacity and the borrower’s payment behavior to calculate the estimated incurred loan loss. Through these categories, we differentiate the normal loan portfolio from the impaired one.

These are our categories:

Debtors may be classified in risk categories A1, A2, A3 or B (A is applicable if they are current on their payment obligations and show no sign of deterioration in their credit quality and B is different from the A categories by a certain history of late payments), The A categories are distinguished by different PNPs (as defined below),

Debtors classified as C1, C2, C3, C4, D1 or D2 include debtors whose loans with us have been charged off or administered by our Recovery Unit, or identified as impaired by an internal risk committee.,

For loans classified as A1, A2, A3 and B, we assign a specific provision level on an individual basis to each borrower and, therefore, the amount of loan loss allowance is determined on a case by case basis,

Estimated Incurred Loan Loss = Loan Loss Allowance

The estimated incurred loss is obtained by multiplying all risk factors defined in the following equation:

EIL= EXP x PNP x SEV

●

EIL = Estimated Incurred Loan Loss. The estimated incurred loan loss is how much could be lost in the event a debtor does not perform the obligations under the loan.

●

EXP = Exposure. This corresponds to the value of commercial loans.

●

PNP = Probability of Non-Performance. This variable, expressed as a percentage, indicates the probability that a debtor will default, This percentage is associated with the internal rating that we give to each debtor, which is determined by analyzing such parameters as debt servicing capacity.

●

SEV = Severity. This is the effective loss rate given default for debtors in the same segment, which is determined statistically based on the historical effective losses for us for each segment.

Every year, models together with PNP and SEV assumptions, are tested by the Bank’s Credit Risk Department, to ensure that they are appropriate at each reporting date so as to make sure any difference between the estimated incurred losses and real losses is reduced.

These tests focus on the validation of the sufficiency of the Bank’s allowances, and consist of comparisons between actual write-offs to allowances established by the model, and the coverage of the total allowance to actual write-offs in the most current periods. Individual loan classification and improvements to any customer classification are also presented for approval to our Risk Committee.

In accordance with such policy, every year we update appraisals of fair value of collateral before the end of the 24 month period for certain customers and such updated appraisals are considered in the calculation of the allowance for loan losses. The number of updated appraisals performed in 2015 was 43, in 2016 was 142 and 2017 it was 140, and such updated appraisals were performed mainly because of changes in customer conditions (renegotiation deterioration of financial situation increase in credit line).

For loans classified in the C and D categories, loan loss allowances are based mainly on the fair value of the collateral, adjusted for an estimate cost to sell, that each of these loans have. Allowance percentage for each category is then based on the fair value of the collateral, or the expected future cash flow from the loan for each individually evaluated non-performing loans.

Loans analyzed on a group basis

The Bank uses the concept of estimated incurred loss to quantify the allowances levels over loan analyzed on a group basis. Incurred loss is the expected provision expense that will appear one year away from the balance date of the transaction’s credit risk, considering the counterpart risk and the collateral associated to each transaction.

Following the Bank’s definition, the Bank uses group evaluation to approach transactions that have similar credit risk features, which indicate the debtor’s payment capacity of the entire debt, capital and interests, pursuant to the contract’s terms. In addition, this allows us to assess a high number of transactions with low individual amounts, whether they belong to individuals or small sized companies. Therefore, debtors and loans with similar features are grouped together and each group has a risk level assigned to it. These models are meant to be used mainly to analyze loans granted to individuals (including consumer loans, credit lines, mortgage loans and commercial loans) and commercial loans to SMEs.

Allowances are established using these models, taking into account the historical impairment and other known circumstances at the time of evaluation. After this, a historical loss rate is assigned to each portfolio profile constituting each segment. The method for assigning a profile is established based on a statistical building method, establishing a relation through a logistic regression various variables, such as payment behavior in the Bank, payment behavior outside the Bank, various socio-demographic data, among others, and a response variable that determines a client’s risk level, which in this case is 90 days of non-performance. Afterwards, common profiles are established related to a logical order and with differentiate default rates, applying the real historical loss the Bank has had with that portfolio.

Our models for loans analyzed on a group basis (consumer loans, residential mortgage loans and small-and-mid-sized commercial loans) are monitored on a monthly basis with respect to predictability and stability, using indices that seek to capture the underlying need to update the models for current loss trends. Therefore, the periods of historical net charge-offs used in the allowance model may be more than a year old as we only update the historical net charge-offs only when our assessment of predictability and stability indicators determine it is necessary.

The different risk categories are constructed and updated periodically based on the payment behavior of the client’s profile to which they belong, as well as his or her socio-demographic characteristics. Therefore, when a customer has past due balance or has missed some payments, the outcome is that the customer will move to a different segment with a higher loss rate, therefore capturing current trends for each risk profile.

Once the customers have been classified, the loan loss allowance is the product of three factors: Exposure (EXP), Probability of Non-Performance (PNP) and Severity (SEV).

EXP = Exposure. This corresponds to the value of commercial loans

PNP = Probability of Non-Performing. This variable, expressed as a percentage, indicates the probability that a debtor will default. This percentage is associated with the internal score that we give to each debtor, which is determined by analyzing such parameters as debt servicing capacity (including, usually, projected cash flows), the company’s financial history, the solvency and capacity of shareholders and management, and projections for the economic sector in which it operates. The internal rating can be different from ratings obtained from external third parties.

SEV = Severity. This is the effective loss rate given default for debtors in the same segment, which is determined statistically based on the historical effective losses for us for each segment.

Allowances for consumer loans

The estimated incurred loss rates for consumer loans correspond to charge-offs net of recoveries. The methodology establishes the period in which the estimated incurred loss for each risk profile emerges. Once the loss has been considered to have been incurred, the estimated incurred loss rates are applied to the corresponding risk profile to obtain the net charge-off level associated with this period. The loss rates applied to each risk profile are based only on the historical net charge-off data for that specific profile within one of the four groups of consumer loans. No other statistical or other information other than net charge-offs is used to determine the loss rates.

The following diagrams set forth the allowances required by our current models for consumer loans:

Santander:

Bank	Loan type				Allowance Level(1) (Loss rate)
Consumer	Performing		New clients				Existing clients		Banefe
			0.53% -19.75%				0.05%-11.92%		0.13%-18.67%

	Renegotiated consumer loans which were less than 90 days past due at the time of renegotiation (2)				3.66%-30.40%				10.19%-43.71%

	Renegotiated consumer loans which were more than 90 days past due at the time of renegotiation (2)				41.50%-100%				51.11%-100%

	Non-performing	Days Past Due		New Clients		Existing Clients		Previously Renegotiated Bank		Previously Renegotiated Banefe
		90-120		31.78%		31.78%		41.50%		51.11%
		120-150		51.17%		51.17%		60.15%		66.65%
		150-180		59.98%		59.98%		68.86%		78.50%
		>180					Charged-off

Percentage of loans outstanding

This category relates only to loans which were renegotiated and were less than 90 days past due at the time of renegotiation, migrating from such category as they reached 90 days past due since renegotiation.

There are two renegotiated categories in our consumer loan portfolio:

Renegotiated Consumer which were less than 90 days past due at the time of renegotiation. The allowance for loan loss percentages (or loss rates) are assigned based on eight different risk profiles which are determined based on demographic and payment behavior variables.

Renegotiated Consumer which were more than 90 days past due at the time of renegotiation. The loss rates are assigned based on four different risk profiles which are determined based on the number of days overdue at the time of renegotiation:

Profile 1: 180 or more days past due

Profile 2: between 150 and 180 days past due

Profile 3: between 120 and 150 days past due

Profile 4: between 90 and 120 days past due

Small- and mid-sized commercial loans

To determine the estimated incurred loss for individuals (natural persons), small- and mid-sized commercial loans collectively evaluated for impairment, we mainly analyze the payment behavior of clients, particularly the payment behavior of clients with payments that are 90 days or more past-due, clients with other weaknesses, such as early non-performance (i.e., payments that are past-due, though by less than 90 days), clients with modified loans and clients with renegotiated loans, as well as success in recovery against these clients. We also consider whether the loan has underlying mortgage collateral.

The risk categories are such that when a customer has a past-due balance or has missed some payments, the outcome is that the customer will move to a different risk category with a higher loss rate, therefore capturing current trends of the customer and, in the aggregate, current trends in the market.

In order to calculate the estimated incurred loan loss for all commercial loans collectively evaluated for impairment, the Bank sub-divided the portfolio in the following way:

Loan type		Allowance Level(1) (Loss rate)
Commercial loans analyzed on a group basis	Performing	Commercial loan to individuals w/o mortgage collateral	Commercial loan to individuals with mortgage collateral	Small Enterprise	Mid-sized Enterprise
	Performing	0.87% -15.70%	0.03%-3.98%	0.21%-14.39%	0.14%-7.31

	Renegotiated commercial loans which were less than 90 days past due at the time of renegotiation (2)	loan w/o mortgage collateral 2.93%-20.65%			loan with mortgage collateral 1.17%-8.25%

	Renegotiated commercial loans which were more than 90 days past due at the time of renegotiation (2)	Days Past Due when renegotiated	Commercial loan to individuals w/o mortgage collateral	Commercial loan to individuals with mortgage collateral	Small Enterprise	Mid-sized Enterprise
		90-179	41.69%	12.15%	30.95%	18.93%
		180-359	67.31%	23.42%	64.47%	51.86%
		360-719	75.69%	34.65%	70.15%	63.12%
		>720	83.82%	46.25%	74.53%	72.87%

	Non-performing consumer	Days Past Due	Commercial loan to individuals w/o mortgage collateral	Commercial loan to individuals with mortgage collateral	Small Enterprise	Mid-sized Enterprise	Previously renegotiated
		90-179	41.69%	12.15%	30.95%	18.93%	18.93%

Allowances for residential mortgage loans

The provision methodology for residential mortgage loans takes into consideration different factors in order to group customers with less the 90 days past due into seven different risk profiles. Factors considered, in the first place, are whether the customer is a new customer or with prior history with the Bank, For each of these main categories additional factors are considered in order to develop risk profiles within each risk category, including payment behavior, non-performance less than 90 days, collateral levels, renegotiation history with the Bank, and historical amounts of net charge-offs, among others. The explanation for the initial segregation into three categories, existing, new customer, is as follows: an existing customer is a customer for which there is a broader level of information and history of payment behavior with the Bank, while for a new customer the Bank has no history of payment behavior and only information from the banking system and credit bureaus is available. The risk categories are such that when a customer’s payment behavior deteriorates, the outcome is that the customer will move to a different risk category with a higher loss rate, therefore capturing the current status of the customer.

Previous to 2016, mortgage loans with more than 90 days past due balances are assigned a loss rate of 11.01%. In 2016, mortgage loans more than 90 days past due balances are assigned a loss rate depending on the loan to value. We determined that 90 days is appropriate, since our historical analysis of customer’s behavior has shown that after 90 days, customers are likely to default on their obligations, and that, over succeeding periods, the loss incurred does not increase given the high fair value of collateral percentage to loan amount required under our credit policies for this type of loan. Also, we note that the Chilean economy’s stability over the last few years has not resulted in other than insignificant fluctuations in collateral fair values on residential mortgage loan properties.

The following table sets forth the required loan loss allowance for residential mortgage loans:

Bank	Loan type	Allowance Level(1) (Loss rate)

Residential mortgage	Performing	Bank (excl Select)		Santander Select
	Performing	0.00%-5.18%		0.00%-3.88%

	Renegotiated mortgage loans which were less than 90 days past due at the time of renegotiation (2)	0.16%-8.37%

	Renegotiated mortgage loans which were more than 90 days past due at the time of renegotiation (2)	5.58%-26.25%

	Non-performing mortgage	Loan to Value
		0-60	5.58%

Credit quality

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.

See credit quality of loans above.

In relation to the credit quality of the investment portfolio, local regulations specify that banks are able to hold only local and foreign fixed–income securities except in certain cases. Additionally, Banco Santander Chile has internal policies to ensure that only securities approved by the Market Risk department, which are stated in the documents “APS” – Products and underlying Approval, are acquired. The Credit Risk Department sets the exposure limits to those approved APS’s. The APS is updated on daily basis.

As of December 31, 2017, 76% of our total investment portfolio correspond to securities issued by the Chilean Central Bank and US treasury notes.

Foreign derivative contracts

As of December 31, 2018, the Bank’s foreign exposure -including counterparty risk in the derivative instruments’ portfolio- was USD 2,090 million or 40.27% of assets. In the table below, exposure to derivative instruments is calculated by using the equivalent credit risk; which equals the replacement carrying amount plus the maximum potential value, considering the cash collateral that minimizes exposure.

Below, there are additional details regarding our exposure for those countries classified above 1 and represents our majority of exposure to categories other than 1, Below we detail as of December 31, 2018, considering fair value of derivative instruments.

Security interests and credit improvements

The maximum exposure to credit risk is reduced in some cases by security interests, credit improvements, and other actions which mitigate the Bank’s exposure. Based on the foregoing, the creation of security interests are a necessary but not a sufficient condition for granting a loan; accordingly, the Bank’s acceptance of risks requires the verification of other variables and parameters, such as the ability to pay or generate funds in order to mitigate the risk being taken on.

The procedures used for the valuation of security interests utilize the prevailing market practices, which provide for the use of appraisals for mortgage securities, market prices for stock securities, fair value of the participating interest for investment funds, etc. All security interests received must be instrumented properly and registered on the relevant register, as well as have the approval of legal divisions of the Bank.

The risk management model includes assessing the existence of adequate and sufficient guarantees that allow recovering the credit when the debtor’s circumstances prevent them from fulfilling their obligations.

The Bank has classification tools that allow it to group the credit quality of transactions or customers. Additionally, the Bank has historical databases that keep this internally generated information to study how this probability varies. Classification tools vary according to the analyzed customer (commercial, consumer, SMEs, etc,).

Credit risk mitigation techniques

The Bank applies various methods of reducing credit risk, depending on the type of customer and product. As we shall see, some of these methods are specific to a particular type of transaction (e,g, real estate guarantees) while others apply to groups of transactions (e,g, netting and collateral arrangements).

Collateral

Banco Santander controls the credit risk through the use of collateral in its operations. Each business unit is responsible for credit risk management and formalizes the use of collateral in its lending policies.

Banco Santander uses guarantees in order to increase their resilience in the subject to credit risk operations. The guarantees can be used fiduciary, real, legal structures with power mitigation and compensation agreements. The Bank periodically reviews its policy guarantees by technical parameters, normative and also its historical basis, to determine whether the guarantee is legally valid and enforceable.

Credit limits are continually monitored and changed in customer behavior function. Thus, the potential loss values represent a fraction of the amount available.

Collateral refers to the assets pledged by the customer or a third party to secure the performance of an obligation. Collateral may be:

●

Financial: cash, security deposits, gold, etc.

●

Non-financial: property (both residential and commercial), other movable property, etc.

One very important example of financial collateral is the collateral agreement. Collateral agreements comprise a set of highly liquid instruments with a certain economic value that are deposited or transferred by a counterparty in favor of another party in order to guarantee or reduce any counterparty credit risk that might arise from the portfolios of derivative transactions between the parties in which there is exposure to risk.

Collateral agreements vary in nature but, whichever the specific form of collateralisation may be, the ultimate aim, as with the netting technique, is to reduce counterparty risk.

Transactions subject to a collateral agreement are assessed periodically (normally on a daily basis). The agreed-upon parameters defined in the agreement are applied to the net balance arising from these assessments, from which the collateral amount (normally cash or securities) payable to or receivable from the counterparty is obtained.

For real estate collateral periodic re-appraisal processes are in place, based on the actual market values for the different types of real estate, which meet all the requirements established by the regulator.

Specifically, mortgage loans are secured by a real property mortgage, and threshold mitigate counterparty credit risk of derivative instruments, (See note 9 c) ii) and iii), for a detail of the impaired portfolio and non-performing loans with or without guarantee).

Personal guarantees and credit derivatives

Personal guarantees are guarantees that make a third party liable for another party’s obligations to the Bank. They include, for example, security deposits and standby letters of credit. Only guarantees provided by third parties that meet the minimum requirements established by the supervisor can be recognised for capital calculation purposes.

Credit derivatives are financial instruments whose main purpose is to hedge credit risk by buying protection from a third party, whereby the Bank transfers the risk of the issuer of the underlying instrument. Credit derivatives are OTC instruments, i.e. they are not traded in organized markets.

Credit derivative hedges, mainly credit default swaps, are entered into with leading financial institutions.

Assets Received in Lieu of Payment

Assets received or awarded in lieu of payment of loans and accounts receivable from clients are recognised at their fair value (as determined by an independent appraisal). The excess of the outstanding loan balance over the fair value is charged to net income for the period, under “Provision for loan losses”. Any excess of the fair value over the outstanding loan balance, less costs to sell of the collateral, is returned to the client. These assets are subsequently adjusted to their net realizable value less cost to sale (assuming a forced sale).

At December 31, 2018, assets received or awarded in lieu of payment amounted to Ch$38,326 million (gross amount: Ch$39,049 million ; allowance: Ch$723 million).

At December 31, 2017, assets received or awarded in lieu of payment amounted to Ch$44,624 million (gross amount: Ch$45,704 million ; allowance: Ch$1,440 million).

Liquidity risk

Liquidity risk is the risk that the Bank may have difficulty meeting the obligations associated with its financial obligations.

Liquidity risk management

The Bank is exposed on a daily basis to requirements for cash funds from various banking activities, such as wires from checking accounts, fixed-term deposit payments, guarantee payments, disbursements on derivatives transactions, etc. As typical in the banking industry, the Bank does not hold cash funds to cover the balance of all the positions, as experience shows that only a minimum level of these funds will be withdrawn, which can be accurately predicted with a high degree of certainty.

The Bank’s approach to liquidity management is to ensure-- whenever possible--to have enough liquidity on hand to fulfill its obligations at maturity, in both normal and stressed conditions, without entering into unacceptable debts or risking the Bank’s reputation. The Board establishes limits on the minimal part of available funds close to maturity to fulfill said payments as well as over a minimum level of interbank operations and other loan facilities that should be available to cover transfers at unexpected demand levels. This is constantly reviewed. Additionally, the Bank must comply with the regulation limits established by the SBIF for maturity mismatches.

These limits affect the mismatches of future flows of income and expenditures of the Bank on an individual basis. They are:

mismatches of up to 30 days for all currencies, up to the amount of basic capital

ii.

mismatches of up to 30 days for foreign currencies, up to the amount of basic capital

iii.

mismatches of up to 90 days for all currencies, twice the basic capital

The Bank’s treasury department (“Treasury”) receives information from all business units about the liquidity profile of its financial assets and liabilities in addition to details from other future cash flows that arise from future business transactions. Based on this information. Treasury keeps a short-term liquid assets portfolio, mainly composed of liquid investments, interbank loans, and advanced payments, to guarantee that the Bank has enough liquidity, Liquidity needs of business units are fulfilled through short-term transfers from Treasury to cover any short-term variation and long-term financing to address all structural liquidity requirements.

The Bank monitors its liquidity position daily to establish future flows of inflow and outflow. At each month’s closing, stress tests are carried out in which a variety of scenarios are used, from normal market conditions to those that contain significant fluctuations. Liquidity policy and procedures are subjected to review and approval of the Bank’s Board. There are periodic reports which detail the Bank’s, and its subsidiaries’, liquidity position, including any exceptions and adopted correcting measures, which are also reviewed periodically by the ALCO.

The Bank relies on customer (retail) and institutional deposits, obligations to banks, debt instruments, and time deposits as its main sources of funding. Although most obligations to banks, debt instruments and time deposits have maturities of more than one year, customer (retail) and institutional deposits tend to have shorter maturities and a large proportion of them are payable within 90 days. The short-term nature of these deposits increases the Bank’s liquidity risk, and hence, the Bank actively manages this risk through continual supervision of the market trends and price management.

Liquidity management seeks to ensure that, even under adverse conditions, we have access to the funds necessary to cover client needs, maturing liabilities and capital requirements. Liquidity risk arises in the general funding for our financing, trading and investment activities. It includes the risk of unexpected increases in the cost of funding the portfolio of assets at appropriate maturities and rates, the risk of being unable to liquidate a position in a timely manner at a reasonable price and the risk that we will be required to repay liabilities earlier than anticipated.

The following table sets forth the balance of our liquidity portfolio managed by our Financial Management Division in the manner in which it is presented to the Asset and Liability Committee (ALCO) and the Board. The ALCO has determined that our liquidity portfolio must be comprised of cash plus assets that can be readily convertible into cash either through the Chilean Central Bank window, overnight deposits or instruments or the local secondary market. The management of the Bank’s liquidity portfolio is performed by the Financial Management Division under rules determined by the ALCO.

Exposure to liquidity risk

A similar, yet not identical, measure is the calculation used to measure the Bank´s liquidity limit as established by the SBIF. The Bank determines a mismatch percentage for purposes of calculating such liquidity limit which is calculated by dividing its benefits (assets) by its obligations (liabilities) according to maturity based on estimated repricing. The mismatch amount permitted for the 30 day and under period is 1 times [regulatory] capital and for the 90 day and under period – 2 times [regulatory] capital.

Market risk

Market risk arises as a consequence of the market activity, by means of financial instruments whose value can be affected by market variations, reflected in different assets and financial risk factors. The risk can be diminished by means of hedging through other products (assets/liabilities or derivative instruments) or terminating the open transaction/position. The objective of market risk management is to manage and control market risk exposure within acceptable parameters.

There are four major risk factors that affect the market prices: type of interest, type of exchange, price, and inflation, In addition and for certain positions, it is necessary to consider other risks as well, such as spread risk, base risk, commodity risk, volatility or correlation risk.

Market risk management

The Bank’s internal management measure market risk based mainly on the procedures and standards of Banco Santander Spain, which are in turn based on an analysis of three principal components:

trading portfolio

domestic financial management portfolio

foreign financial management portfolio

The trading portfolio is comprised mainly of investments, valued at fair value, and free of any restriction on their immediate sale, which are often bought and sold by the Bank with the intent of selling them in the short term in order to benefit from short-term price fluctuations. The financial management portfolios include all the financial investments not considered a part of trading portfolio.

The ALCO has the general responsibility for the market risk. The Bank’s risk/finance department is responsible for formulating detailed management policies and applying them to the Bank’s operations, in conformity with the guidelines adopted by the ALCO and the Global Risk Department of Banco Santander Spain.

The department’s functions in connection with trading portfolio include the following:

apply the “Value at Risk” (VaR) techniques to measure interest rate risk

ii.

adjust the trading portfolios to market and measure the daily income and loss from commercial activities

iii.

compare the real VaR with the established limits

iv.

establish procedures to prevent losses in excess of predetermined limits

furnish information on the trading activities to the ALCO, other members of the Bank’s management, and the Global Risk Department of Banco Santander Spain

The department’s functions in connection with financial management portfolios include the following:

perform sensitivity simulations (as explained below) to measure interest rate risk for activities denominated in local currency and the potential losses forecasted by these simulations

ii.

provide daily reports thereon to the ALCO, other members of the Bank’s management, and the Global Risk Department of Banco Santander Spain

Market risk - trading portfolio

The Bank applies VaR methods to measure the market risk of its trading portfolio. The Bank has a consolidated commercial position that is made up of fixed income investments, foreign exchange trading, and a minimum position of investments in equity shares. This portfolio is mostly made of Chilean Central Bank bonds, mortgage bonds and corporate bonds issued locally at low risk, At the closing date, the trading portfolio did not show investments in another portfolio.

For the Bank, the VaR estimate is done through the historical simulation method which consists of observing the behavior of profit and loss that might have taken place with the current portfolio if the market conditions at a given time had been present and, based on that information, infer maximum losses with a determined confidence level. This method has the advantage of reflecting precisely the historical distribution of market values and not requiring any distribution assumption for a specific probability. All VaR measures are designed to establish the distribution function for the value change in a given portfolio and, once this distribution is known, to calculate the percentile related to the necessary confidence level, which will match the risk value in relation to of those parameters, As calculated by the Bank, the VaR is an estimate of the maximum expected loss of market value of a given portfolio in one day, with 99.00% confidence. It is the maximum loss in one day the Bank could expect in a given portfolio with a confidence level of 99.00%. In other words, it is the loss the Bank would have to deal only 1.0% of the time, VaR provides a single estimation of the market risk that cannot be compared with other market risks, Returns are calculated using a time window of 2 years or, at least, 520 data points gathered since the reference date in the past to calculate VaR.

The Bank does not calculate three separate VaRs. Only one VaR is calculated for the entire trading portfolio which, in addition, is separated into risk types. The VaR program carries out a historical simulation and calculates a profit (ganancia or “G”) and loss (pérdida or “P”) G&P Statements for 520 data points (days) for each risk factor (fixed income, currency, and variable income). Each risk factor’s G&P is added and a consolidated VaR is calculated with 520 data points or days. In addition, the VaR is calculated for each risk factor based on the individual G&P calculated for each. Additionally, a weighted VaR is calculated following the above mentioned method but giving a larger weight to the 30 most recent data points. The highest VaR is reported, In 2017 and 2016, we were still using the same VaR model and the methodology has not changed.

The Bank uses VaR estimates to issue a warning in case the statistically estimated losses for the trading portfolio exceed the cautionary levels.

Limitations of the VaR model

When applying a calculation methodology, no assumptions are made regarding the probability distribution of the changes in the risk factors; the historically observed changes are used for the risk factors on which each position in the portfolio will be valued.

It is necessary to define a valuation function fj(xi) for each instrument, preferably the same one used to calculate the market value and income of the daily position. This valuation function will be applied in each scenario to generate simulated prices for all the instruments in each scenario.

In addition, the VaR methodology should be interpreted taking into consideration the following limitations:

Changes in market rates and prices may not be independent and identically distributed random variables, and may not have a normal distribution. In particular, the assumption of normal distribution may underestimate the probability of extreme market movements;

The historical data used by the Bank may not provide the best estimate of the joint distribution of changes in the risk factors in the future, and any modification of the data may be inadequate. In particular, the use of historical data may fail to capture the risk of potential extreme and adverse market fluctuations, regardless of the time period used;

A 1-day time horizon may not fully capture the market risk positions which cannot be liquidated or covered in a single day. It would not be possible to liquidate or cover all the positions in a single day;

The VaR is calculated at the close of business, but trading positions may change substantially in the course of the trading day;

The use of a 99% level of confidence does not take account of, or make any statement about, the losses that could occur outside of that degree of confidence; and

A model such as the VaR does not capture all the complex effects of the risk factors over the value of the positions or portfolios, and accordingly, it could underestimate potential losses.

At no time in 2018 and 2017 did the Bank exceed the VaR limits in connection with the three components which comprise the trading portfolio: fixed-income investments, variable-income investments and foreign currency investments.

The Bank carries out back-testings on a daily basis and, generally, discovers that trading losses exceed the estimated VaR approximately one out of hundred business days. Also, a maximum VaR limit was established that can be applied over the trading portfolio. Both in 2018 and 2017, the Bank has kept within the maximum limit it established for the VaR; even when the real VaR exceeded estimations.

High, low and average levels for each component and year were as follows:

VaR	2018 USDMM	2017 USDMM
Consolidated:
High	5.23	5.71
Low	1.21	1.56
Average	2.01	3.01

Fixed-income investments:
High	2.54	5.51
Low	1.19	1.15
Average	1.71	2.36

Variable-income investments

Low	0.00	0.00
Average	0.00	0.00

Foreign urrency investments
High	4.29	4.21
Low	0.09	0.53
Average	1.14	1.71

Market risk - local and foreign financial management

The Bank’s financial management portfolio includes most of the Bank’s non-trading assets and liabilities, including the credit/loan portfolio. For these portfolios, investment and financing decisions are strongly influenced by the Bank’s commercial strategies.

The Bank uses a sensitivity analysis to measure market risk for domestic and foreign currencies (not included in the trading portfolio). The Bank carries out a simulation of scenarios that will be calculated as the difference between current flows in the chosen scenario (curve with a parallel movement of 100 basis points (“bp”) in all its sections) and its value in the base scenario (current market). All positions in domestic currency indexed to inflation (UF) are adjusted by a sensitivity factor of 0.57 which represents a change in the curve of 57bp in all real rates and 100 bp in nominal rates. The same scenario is carried out for net positions in foreign currency and interest rates in USD. In addition, the Bank has established limits regarding maximum loss this kind of movement in interest rates can have over capital and net financial income budgeted for the year.

To establish the consolidated limit, we add the foreign currency limit to the domestic currency limit and multiple by 2 the sum of the multiplication of them together both for net financial loss limit as well as for the capital and reserves loss limit, using the following formula:

Consolidated limit = square root of a2 + b2 + 2ab

a: domestic currency limit

b: foreign currency limit

Since we assume the correlation is 0; 2ab = 0 2ab = 0

Limitations of the sensitivity models

The most important assumption is using an exchange rate of 100 bp based on yield curve (57 bp for real rates). The Bank uses a 100 bp exchange since sudden changes of this magnitude are considered realistic. Santander Spain Global Risk Department has also established comparable limits by country, so as to compare, control and consolidate market risk by country in a realistic and orderly fashion.

In addition, the sensitivity simulation methodology should be interpreted taking into consideration the following limitations:

The simulation of scenarios assumes that the volumes remain consistent in the Bank’s Consolidated Statements of Financial Position and are always renewed at maturity, thereby omitting the fact that certain credit risk and prepayment considerations may affect the maturity of certain positions.

This model assumes an identical change along the entire length of the yield curve and does not take into account the different movements for different maturities,

The model does not take into account the volume sensitivity which results from interest rate changes.

The limits to losses of budgeted financial income are calculated based on the financial income foreseen for the year, which may not be actually earned, meaning that the real percentage of financial income at risk may be higher than the expected one.

Capital risk

The Group defines capital risk as the risk that the Group or any of its companies may have an insufficient amount and/or quality of capital to: meet the minimum regulatory requirements in order to operate as a bank; respond to market expectations regarding its creditworthiness; and support its business growth and any strategic possibilities that might arise, in accordance with its strategic plan.

The objectives in this connection include most notably:

•

To meet the internal capital and capital adequacy targets

•

To meet the regulatory requirements

•

To align the Bank’s strategic plan with the capital expectations of external agents (rating agencies, shareholders and investors, customers, supervisors, etc,)

•

To support the growth of the businesses and any strategic opportunities that may arise

The Group has a capital adequacy position that surpasses the levels required by regulations.

Capital management seeks to optimize value creation at the Bank an at its different business segment. The Bank continuously evaluates it risk-return ratios through its basic capital, effective net equity, economic capital and return on equity. With regard to capital adequacy, the Banks conducts its internal process based on the SBIF standards which are based on Basel Capital Accord (Basel I). Economic capital is the capital required to support all the risk of the business activity with a given solvency level.

Capital is managed according to the risk environment, the economic performance of Chile and the business cycle. Board may modify our current equity policies to address changes in the mentioned risk environment.

Minimum Capital

Under the General Banking Law, a bank is required to have a minimum of UF800,000 (approximately Ch$21,438 million or U.S.$34,7 million as of December 31, 2018) of paid-in capital and reserves, calculated in accordance with Chilean GAAP.

Capital adequacy requirement

Chilean banks are required by the General Banking Law to maintain regulatory capital of at least 8% of risk-weighted assets, net of required loan loss allowance and deductions, and paid-in capital and reserves (“basic capital”) of at least 3% of total assets, net of required loan loss allowances, Regulatory capital and basic capital are calculated based on the consolidated financial statements prepared in accordance with the Compendium of Accounting Standards issued by the SBIF the Chilean regulatory agency. As we are the result of the merger between two predecessors with a relevant market share in the Chilean market, we are currently required to maintain a minimum regulatory capital to risk-weighted assets ratio of 11%. As of December 31, 2017, the ratio of our regulatory capital to risk-weighted assets, net of loan loss allowance and deductions, was 13.91% and our core capital ratio was 10.99%.

Regulatory capital is defined as the aggregate of:

●

a bank’s paid-in capital and reserves, excluding capital attributable to subsidiaries and foreign branches or basic capital;

●

its subordinated bonds, valued at their placement price (but decreasing by 20.0% for each year during the period commencing six years prior to maturity), for an amount up to 50.0% of its basic capital; and

●

its voluntary allowances for loan losses for an amount of up to 1.25% of risk weighted-assets.

The levels of basic capital and effective net equity at the close of each period are as follows:

			Ratio
	As of December 31,		As of December 31,
	2018	2017	2018	2017
	MCh$	MCh$	%	%
Basic capital	3,239,546	3,066,180	7.72	7.92
Regulatory capital	4,101,664	3,881,252	13.40	13.91

Risk Concentration

The Bank operates mainly in Chile, thus most of its financial instruments are concentrated in that country. See Note 39, credit risk to see concentration of the Bank’s loans and accounts receivable by industry above.
