Loans And Account Receivable At Fair Value Through Other Comprehensive Income [Abstract]

LOANS AND ACCOUNTS RECEIVABLE AT FAIR VALUE THROUGH OTHER COMPREHENSIVE INCOME

NOTE 10

LOANS AND ACCOUNTS RECEIVABLE AT FAIR VALUE THROUGH OTHER COMPREHENSIVE INCOME

The Bank classifies certain loans at fair value through other comprehensive income (FVOCI), when a loan exceeds single client exposure under the Bank's credit risk policy. Initially, the risk committee approved the full operation but with the condition to sell a portion of the loan in the medium term.

Additionally, the Bank includes operations that expect to sell, for which an increase of the credit risk has been identified.

This portfolio is measured at fair value, recognizing the adjustment in other comprehensive income. The portfolio is assessed for impairment loss under the ECL model, same as loans at amortized cost.

An analysis of changes in the gross carrying amount and the corresponding ECL allowance is, as of December 31, 2021 is as follows:

Guarantee deposits (margin accounts) correspond to collateral associated with derivative financial contracts to mitigate the counterparty credit risk and are mainly established in cash. These guarantees operate when mark to market of derivative financial instruments exceed the levels of threshold agreed in the contracts, which could result in the Bank delivering or receiving collateral.

⁽³⁾

Corresponds to the interests in Redbanc S.A., Transbank S.A. and Nexus S.A., which were reclassified as non-current assets classified as held for sale in accordance with IFRS 5 “Non-current assets held for sale and discontinued operations”. In December 2021, the Bank reversed that reclassification and has presented them as Investment in associates. For additional information see Note 1 v) and Note 39.

⁽⁴⁾

Under this item, the Bank has recorded prepaid expense related to the Santander LATAM Pass program, which is consumed on a monthly basis in accordance with the client use of Bank’s transactional products and therefore the Bank assigned the respective LATAM Pass miles. In May 2020, LATAM Airlines Group S.A began a reorganization process under Chapter 11, with an aim to continue operating. LATAM has publicly stated its intention to honor all current and future tickets, as well as travel vouchers, miles and frequent flyer programs, which has been ratified by the bankruptcy court of New York (in charge of chapter 11). In addition, LATAM formalized two tranches of the DIP (Debtor in Possession) financing proposal for a total of USD 2,200 million, obtaining all resources necessary to continue operating during the crisis. In October 2020, the company made its first disbursement for US$1,150 million from the DIP financing, which represents 50% of the amount available and allowed to reestablish its operations and start preparing its reorganization plan. On January 27, 2021, the request made by LATAM to postpone the deadline for submitting its reorganization plan was approved. On November 26, 2021, LATAM submitted to the Bankruptcy court a Reorganization Plan supported by main stakeholders to strengthen the capital structure and long-term sustainability. The plan includes the injection of US$8,190 million through capital, convertible bonds and debt, which will allow the company to exit from Chapter 11 with appropriate capitalization to execute its business plan.

Accounting Policies [Abstract]

Basis of preparation for the Consolidated Financial Statements

The Consolidated Financial Statements for the years ended December 31, 2021, 2020 and 2019, incorporate the financial statements of the entities over which the Bank has control (including structured entities); and includes the adjustments, reclassifications and eliminations needed to comply with the accounting and valuation criteria established by IFRS. Control is achieved when the Bank:

has power over the investee;

II.

is exposed, or has rights, to variable returns from its involvement with the investee; and

III.

has the ability to use its power to affect its returns.

The Bank reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. When the Bank has less than a majority of the voting rights of an investee, it has power over the investee when the voting rights are sufficient to give it the practical ability to direct the relevant activities over the investee unilaterally. The Bank considers all relevant facts and circumstances in assessing whether or not the Bank’s voting rights in an investee are sufficient to give it power, including:

●

the size of the Bank’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders;

●

potential voting rights held by the Bank, other vote holders or other parties;

●

rights arising from other agreements; and

● any additional facts and circumstances that indicate that the Bank has, or does not have, the current ability to direct the relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings.

Consolidation of a subsidiary begins when the Bank obtains control over the subsidiary and ceases when the Bank loses control over the subsidiary. Specifically, income and expenses of a subsidiary acquired or disposed of during the year are included in the Consolidated Statements of Income and Comprehensive Income from the date the Bank gains control until the date when the Bank ceases to control the subsidiary.

Profit or loss and each component of other comprehensive income are attributed to the owners of the Bank and to the non-controlling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Bank and to the non-controlling interests even if this results in the non-controlling interests having a deficit in certain circumstances.

When necessary, adjustments are made to the financial statements of the subsidiaries to ensure their accounting policies are consistent with the Bank’s accounting policies. All intragroup assets, liabilities, equity, income, expenses and cash flows relating to transactions between consolidated entities are eliminated in full on consolidation.

Changes in the consolidated entities ownership interests in subsidiaries that do not result in a loss of control over the subsidiaries are accounted for as equity transactions. The carrying values of the Bank’s equity and the non-controlling interests’ equity are adjusted to reflect the changes to their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to owners of the Bank.

In addition, third parties’ shares in the Bank’s consolidated equity are presented as “Non-controlling interests” in the Consolidated Statements of Changes in Equity. Their share in the income for the year is presented as “Attributable to non-controlling interest” in the Consolidated Statements of Income.

The following companies are considered entities controlled by the Bank and are therefore within the scope of consolidation:

On December 18, 2019, Santander Agente de Valores Limitada changed its business name to Santander Asesorías Financieras Limitada and the company’s object, start offering financial advice.

(2)

On October 19, 2019 Klare Corredora de Seguros S.A. was created as a digital insurance brokerage and supporting banking business company and thus is subject to banking regulations. The Banks owns the 50.10% of the company’s capital share.

(3) On November 15, 2019, Financial Market Commission (FMC) authorized Banco Santander to acquire the 51% of the Santander Consumer Chile S.A. capital share from SK Berge (49%) and Banco Santander S.A. (2%). The sale was completed on November 27, 2019.

(4)

On July 6, 2020, Banco Santander registered as a new subsidiary and business support company named “Sociedad Operadora de Tarjeta de Pago Santander Getnet Chile S.A”.

ii. Entities controlled by the Bank through other considerations

The following companies have been consolidated based on the determination that the Bank has control as previously defined above and in accordance with IFRS 10 “Consolidated Financial Statements” (IFRS 10):

Santander Gestión de Recaudación y Cobranza Limitada (collection services)

Bansa Santander S.A. (financing revolving inventory lines to automotive dealers) ⁽¹⁾

Multiplica SpA (Development card incentive programs) ⁽²⁾

(1)

Since December 2019, Bansa Santander S.A.(“Bansa”) modified it activity to financing revolving inventory lines to automotive dealers. Accordingly, Consumer has started to guide relevant activities of Bansa, and therefore it has begun to consolidate.

(2)

On October 4, 2019 Multiplica Spa was created as a supporting banking business company. In accordance with IFRS 10, the Bank controls the entity, since the relevant activities are addressed by the Bank, and the Bank is exposed, or has rights, to variable returns from its involvement with the investee.

iii. Associates

An associate is an entity over which the Bank has significant influence. Significant influence, in this case, is defined as the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. An investment in an associate is accounted for using the equity method from the date on which the investee becomes an associate.

The following companies are considered “Associates” in which the Bank accounts for its participation using the equity method:

		Place of	Percentage of ownership share
		Incorporation	As of December 31,
		and	2021		2020		2019
Associates	Main activity	operation	%		%		%
Redbanc S.A.	ATM services	Santiago, Chile		33.43		-		-
Transbank S.A.	Debit and credit card services	Santiago, Chile		25.00		-		-
Centro de Compensación Automatizado S.A.	Electronic fund transfer and compensation services	Santiago, Chile		33.33		33.33		33.33
Sociedad Interbancaria de Depósito de Valores S.A.	Delivery of securities on public offer	Santiago, Chile		29.29		29.29		29.29
Cámara Compensación de Alto Valor S.A.	Payments clearing	Santiago, Chile		15.00		15.00		15.00
Administrador Financiero del Transantiago S.A.	Administration of boarding passes to public transportation	Santiago, Chile		20.00		20.00		20.00
Sociedad Nexus S.A. (*)	Credit card processor	Santiago, Chile		-		-		-
Servicios de Infraestructura de Mercado OTC S.A.	Administration of the infrastructure for the financial market of derivative instruments	Santiago, Chile		12.48		12.48		12.48

(*)

The Bank sold the investments in Nexus on December 31, 2020. See Note N°39.

The Bank has re-evaluated the classification of Redbanc and Transbank, due to elapsed time since those companies were classified as held-for-sale, and the fact that it was not possible to find buyers, due to the economic effects of the COVID-19 pandemic and specifically the current Chilean economic situation. Thus, the Bank has reclassified those investments as Investments in associates and accounted using the equity method.

In the case of Cámara Compensación de Pagos Alto Valor S.A., Banco Santander-Chile has a representative on the Board of Directors. As per the definition of associates, the Bank has concluded that it exerts significant influence over those entities.

In the case of Servicios de Infraestructura de Mercado OTC S.A., the Bank actively participates, through its executives, in the administration and in the process of organization, which is why the Administration has concluded that it exerts significant influence on it.

Non-controlling interest

Non-controlling interest

Non-controlling interest represents the portion of net income and net assets which the Bank does not own, either directly or indirectly. It is presented as “Attributable to non-controlling interest” separately in the Consolidated Statements of Income, and separately from shareholders’ equity in the Consolidated Statements of Financial Position.

In the case of entities controlled by the Bank through other considerations, income and equity are presented in full as non-controlling interest, since the Bank controls them, but does not have any ownership expressed as a percentage.

Classification and measurement of financial instrument

Classification and measurement of financial instrument

Financial instruments must be classified and measured in accordance with IFRS 9 starting from January 1, 2018, which established guidance for the financial reporting of financial assets and financial liabilities that will present relevant and useful information to users of financial statements for their assessment of the amounts, timing and uncertainty of an entity’s future cash flows.

I. Classification of financial instrument

i) Classification of financial assets

Financial assets are classified into a measurement category based on both the Bank’s business model for managing the financial asset and the contractual cash flow characteristics of the financial asset.

Contractual cash flow assessment determines if the cash flows from the financial asset meet the SPPI (solely payment of principal and interest) criterion, i.e., whether the contractual terms of the financial asset give rise, on specific dates, to cash flows that are solely payments of principal and interest. Principal is the fair value of the financial assets at initial recognition, and interest is the consideration for the time value of money, the credit risk associated with the principal outstanding, and also may include liquidity risk, administrative cost and profit margin.

For classification process the Bank perform the SPPI test, which assesses the contractual term to identify whether they meet SPI criterion, i.e., the contract is a basic lending arrangement. The Bank applies judgement and considers relevant factors such as currency in which the financial asset is denominated, and period for which the interest rate is set.

Business model refers to how the Bank manages its financial assets in order to generate cash flows. The Bank determined its business model on initial application of IFRS 9 at the level that best reflects how it manages groups of financial assets to achieve its business objective.

The Banks’s business model is not assessed on an instrument-by- instrument basis, but at a higher level of aggregated portfolio and is based on observable factors such as: performance of the financial assets, the risk that affect the performance, and the expected frequency, value and timing of sales.

In accordance with IFRS 9 the business models are:

●

Held to collect business model (HTC) - financial assets that are held within a business model whose objective is to hold assets in order to collect contractual cash flows are managed to realize cash flows by collecting contractual payments over the life of the instrument, under this business model sales made when there is an increase in the credit risk, or to manage credit concentration risk are not inconsistent with a business model whose objective is to hold financial assets to collect contractual cash flows.

●

Held to collect and sell (HTC&S) - financial assets under this business model achieve the objective by both collecting contractual cash flows and selling financial assets, then involve a greater frequency and value of sales than HTC business model.

●

Other business model - financial assets held in this business has the objective of realizing cash flows through the sale of the assets. The Bank makes decisions based on the assets’ fair values and manages the assets to realize those fair values.

In accordance to the above mentioned, financial instruments are assigned to portfolios which represent specific business models. Each portfolio has its proper business objective and seek to face liquidity risk, inflation and interest rate risk effectively.

Due to exceptional changes arose in the liquidity market, changes that we expect to face in the short and middle term, the Bank is requiring to maintain certain collaterals with 2024-2026 maturity to guarantee a loan program led by the Chilean Central Bank (“FCIC”), and also is required to establishing greater Technical Reserves due to increase in currents accounts, time deposits and other on demand deposits from our clients. For this reason, the Bank has to create a new business model “Held-to-collect” whose objective is to manage properly the prevailing high level of liquidity, where additionally the Bank has the intention and the ability to hold them until maturity.

ii) Classification of financial liabilities

The Bank classified all financial liabilities as subsequently measured at amortized cost, except for derivatives that are liabilities, which are measured at fair value through profit or loss.

iii) Reclassification

Reclassification of financial assets is required if, and only if, the objective of the Bank’s business model for managing those financial assets changes. Financial liabilities cannot be reclassified.

II. Measurement of financial instruments

i) Initial measurement

On initial recognition, financial assets and financial liabilities are measured at the transaction price, i.e. the fair value of the consideration given or received (IFRS 13). In the case of financial instruments not at fair value through profit or loss are directly attributable to the acquisition or issue of the financial asset or financial liability.

ii) Subsequent measurement- financial assets

After initial recognition, the Bank shall measure a financial asset at:

(a) Amortized cost

Financial assets that are held in a business model to collect the contractual cash flows and contain contractual terms that give rise on specific dates to cash flows that are SPPI, are measured at amortized cost.

The effective interest method is used in the calculation of the amortized cost of a financial asset or a financial liability and in the allocation and recognition of the interest revenue or interest expense in profit or loss over the relevant period. The effective interest rate (EIR) is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial asset or financial liability to the gross carrying amount of a financial asset or to the amortized cost of a financial liability.

(b) Fair value through other comprehensive income (FVOCI)

Financial assets that are debt instruments held in a business model that is achieved by both collecting contractual cash flows and selling, and that contain contractual terms that give rise on specific dates to cash flows that are SPPI, are measured at FVOCI. They are subsequently remeasured at fair value and changes therein (except for those relating to impairment, interest income and foreign currency exchange gains and losses) are recognized in other comprehensive income, until the assets are sold. Upon disposal, the cumulative gain and losses in OCI are recognized in the income statements.

(c) Fair value through profit or loss (FVTPL)

Financial assets that do not contain contractual terms that give rise on specified dates to cash flows that are SPPI, or if the financial assets, or if the financial asset is not held in a business model that is either (i) a business model to collect the contractual cash flows or (ii) a business model that is achieved by both collecting contractual cash flows and selling.

Financial assets held for trading are recognized at fair value through profit or loss, likewise derivatives contracts for trading purposes.

(d) Equity instruments

For certain equity instruments, the Bank may make an irrevocable election to present subsequent changes in the fair value of the instrument in other comprehensive income, except for dividend income which is recognized in profit or loss. Gains or losses on derecognition of these equity instruments are not transferred to profit or loss.

iii) Subsequent measurement- financial liabilities

After initial recognition, the Bank shall measure a financial liability at amortized cost.

III. Derecognition of financial assets and liabilities

Financial assets are derecognized when, and only when:

	●	the contractual rights to the cash flows from the financial asset expire, or
	●	the Bank transfers substantially all the risks and rewards of ownership of the financial asset, and therefore the Bank derecognizes the financial asset and recognize separately any rights and obligations created or retained in the transfer.

In some cases, the Bank enters into transactions for which it retains the contractual rights to receive the cash flows of the financial asset, but assumes a contractual obligation to pay the cash flows in an arrangement that meets all the conditions required, i.e. the Bank only transfers collected amounts from original assets, selling or pledging original assets is prohibited, and the Bank has the obligation to remit cash flows collected without material delay.

When a financial asset is sold and the Bank simultaneously agrees to repurchase it (or an asset that is substantially the same) at a fixed price on a future date, the Bank continues to recognize the financial assets in their entirety in the statements of financial position because it retains substantially all of the risks and rewards of ownership. The cash consideration received is recognized as a financial asset and a financial liability is recognized for the obligation to pay the repurchase price.

Financial liabilities are derecognized when, and only when, they are extinguished, cancelled or expired.

IV. Contingent loan

The Bank issues contingent liabilities (including letters of credit, foreign letters of credit and performance guarantee) and loan commitments.

Contingent liabilities and undrawn loan commitments are commitments under which, over the duration of the commitment, the Bank is required to provide a loan with pre-specified term to the customer.

The nominal contractual loan value, when the loan agreed to be provided is on market terms, is not recorded in the statements of financial position. The related ECL allowances are disclosed in Note 23.

V. Offsetting of financial instruments

Financial asset and liability balances are offset, i.e., reported in the Consolidated Statements of Financial Position at their net amount, only if there is a legally enforceable right to offset the recorded amounts and the Bank intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously. As of December 31, 2021 and 2020 the Bank does not have balance offsetting of financial instruments.

Derivatives and hedging activities

Derivatives and hedging activities

The Bank has elected to continue applying the hedge accounting requirements of IAS 39 on adoption of IFRS 9.

A “financial derivative” is a financial instrument whose value changes in response to the changes in an underlying observable market variable (such as an interest rate, a foreign exchange rate, a financial instrument’s price, or a market index, including credit ratings), whose initial investment is very small compared with other financial instruments having a similar response to changes in market factors, and which is generally settled at a future date.

For presentation purposes, derivatives are presented in accordance with its positive or negative fair value as assets or liabilities, respectively, and include trading and hedging instruments separately (see Note 6).

Hedging transactions

The bank has elected to continue applying the hedge accounting requirements in IAS 39 instead of the requirements of IFRS 9, thus the Bank uses financial derivatives for the following purposes:

to sell to customers who request these instruments in the management of their market and credit risks;

ii.

to use these derivatives in the management of the risks of the Bank entities’ own positions and assets and liabilities (“hedging derivatives”), and

iii.

to obtain profits from changes in the price of these derivatives (trading derivatives).

All financial derivatives that are not held for hedging purposes are accounted for as trading derivatives.

A derivative qualifies for hedge accounting if all the following conditions are met:

The derivative hedges one of the following three types of exposure:

a. Changes in the value of assets and liabilities due to fluctuations, among others, in the interest rate and/or exchange rate to which the position or balance to be hedged is subject (“fair value hedge”);

b. Changes in the estimated cash flows arising from financial assets and liabilities, and highly probable forecasted transactions (“cash flow hedge”);

c. The net investment in a foreign operation (“hedge of a net investment in a foreign operation”).

It is effective in offsetting exposure inherent in the hedged item or position throughout the expected term of the hedge, which means that:

a. At the date of arrangement the hedge is expected, under normal conditions, to be highly effective (“prospective effectiveness”).

b. There is sufficient evidence that the hedge was actually effective during the life of the hedged item or position (“retrospective effectiveness”).

There must be adequate documentation evidencing the specific designation of the financial derivative to hedge certain balances or transactions and how this effective hedge was expected to be achieved and measured, provided that this is consistent with the Bank’s management of own risks.

The changes in the value of financial instruments qualifying for hedge accounting are recorded as follows:

For fair value hedges, the gains or losses arising on both hedging instruments and the hedged items (attributable to the type of risk being hedged) are included as “Net income (expense) from financial operations” in the Consolidated Statements of Income.

For fair value hedges of interest rate risk on a portfolio of financial instruments (macrohedges), gains or losses that arise in measuring hedging instruments within “Interest income and expense”, and other gains or losses due to changes in fair value of the underlying hedged item (attributable to the hedged risk) are recorded in the Consolidated Statements of Income under “Net income (expense) from financial operations”.

For cash flow hedges, the change in fair value of the hedging instrument is included as “Cash flow hedge” in “Other comprehensive income”.

The differences in valuation of the hedging instrument corresponding to the ineffective portion of the cash flow hedging transactions are recorded directly in the Consolidated Statements of Income under “Net income (expense) from financial operations”.

If a derivative designated as a hedging instrument no longer meets the requirements described above due to expiration, ineffectiveness or for any other reason, hedge accounting treatment is discontinued. When “fair value hedging” is discontinued, the fair value adjustments to the carrying amount of the hedged item arising from the hedged risk are amortized to gain or loss from that date, where applicable.

When cash flow hedges are discontinued, any cumulative gain or loss of the hedging instrument recognized under “Other comprehensive income” (from the period when the hedge was effective) remains recorded in equity until the hedged transaction occurs, at which time it is recorded in the Consolidated Statements of Income, unless the transaction is no longer expected to occur, in which case any cumulative gain or loss is recorded immediately in the Consolidated Statements of Income.

Expected credit losses allowance – under IFRS 9

Expected credit losses allowance – under IFRS 9

Starting from January 1, 2018, the Bank replaced the “incurred loss” model of IAS 39 with an “expected credit loss (ECL)” model established by IFRS 9. The new single impairment model applies to all financial assets measured at amortized cost and fair value through other comprehensive income (FVOCI), including commitment and contingent loans. Investments in equity are outside of the scope of the new impairment requirements.

The Bank accounted ECL related to financial assets measured at amortized cost as a loss allowance in the statements of financial position, but the carrying amount of these assets is stated net of the loss allowance. ECL related to contingent loans is accounted as a provision in the statements of financial position. The Bank recognizes in profit or loss, as an impairment gain or loss, the amount of ECL (or reversal) that is required to adjust the loss allowance at the reporting date to the amount that is required to be recognized in accordance IFRS 9, for financial assets measured at amortized cost and contingent loans.

The new model uses a dual measurement approach, under which the loss allowance is measured as either:

12-month expected credit losses

Lifetime expected credit losses

The Bank evaluates the clients within the corporate commercial loan portfolio, by preparing individual credit proposals, verifying debt servicing capacity (projected cash flow), client’s financial history and projections for economic sector. All proposal includes analysis of the client, rating and recommendation. For corporations, the evaluation includes subsidiaries and affiliates. Smaller commercial loans, mortgage loans and consumer loans are grouped into homogeneous portfolios, based on a combination of internal and external characteristics.

The Bank has defined default on the following basis:

●

corporate: when exposure is more than 89 days past due, it has been restructured, it is in judicial collection, it has been write-off, drag effect define as the entire outstanding amount on any loan which is 89 days or more past due.

●

Smaller commercial, mortgage- and consumer loans: when exposure is more than 89 days past due, it has been restructured, or has been identified as impaired by an internal risk committee).

The measurement basis depends on whether there has been a significant increase in credit risk since initial recognition. Based on changes in credit quality since initial recognition, IFRS 9 outlines a “three-stage” model impairment in accordance with the following diagram:

	Change in credit quality since initial recognition
Stage 1	Stage 2	Stage 3
Initial recognition	Significant increase in credit risk since initial recognition	Credit impaired assets
12-month expected credit losses	Lifetime expected credit losses	Lifetime expected credit losses

The Bank, at the end of each reporting period, evaluated whether financial instrument’s credit risk has significantly increased since initial recognition or whether an asset is considered to be credit-impaired, and consequently classified the financial instrument in the respective stage:

●

Stage 1: When loans are first recognized, the Bank recognizes an allowance based on 12 months ECL. Stage 1 loans also include facilities where the credit risk has improved, and the loan has been returned to Stage 1.

●

Stage 2: When a loan has shown a significant increase in credit risk since origination, the Bank records an allowance for the lifetime ECL. Stage loans also include facilities, where the credit risk has improved, and the loan has been returned to stage 2.

● Stage 3: Loans considered credit impaired. The Bank records an allowance for the lifetime ECL, setting the PD at 100%.

The Bank considers reasonable and supportable information that is available without undue cost or effort and that may affect the credit risk on a financial instrument, including forward looking information to determine a significant increase in credit risk since initial recognition. Forward looking information includes past events, current conditions and forecast or future economic conditions (macro-economic data).

Credit risk assessment and forward-looking information (including macro-economic factors), includes quantitative and qualitative information based on the Bank’s historical experience, some examples are:

Financial or economic conditions that are expected to cause a significant change in the borrower’s ability to meet its debt obligations.

An actual or expected internal credit rating downgrade for the borrower or decrease in behavioral scoring.

An actual or expected significant change in the operating results of the borrower.

Significant increases in credit risk on other financial instruments of the same borrower.

Significant changes in the value of the collateral supporting the obligation or in the quality of third-party guarantees or credit enhancements.

Reductions in financial support from a parent entity or other affiliate.

Expected changes in the loan documentation including an expected breach of contract that may lead to covenant waivers or amendments, interest payment holidays, interest rate step-ups, requiring additional collateral or guarantees, or other changes to the contractual framework of the instrument.

The Bank has considered that if contractual payments are more than 30 days past due, the credit risk is deemed to have increased significantly since initial credit recognition but is not an absolute indicator. The bank did not rebut the backstop presumption of IFRS 9 relating to SICR or default.

Expected credit loss measurement (ECL)

The Bank calculates the ECL allowance mainly through IFRS 9 models and using cash flow discounted methodology.

The ECL are the probability-weighted estimate of credit losses, i.e. the present value of all cash shortfalls. A cash shortfall is the difference between the cash flows that are due to an entity in accordance with the contract and the cash flows that the entity expects to receive. The three main components to measure the ECL are:

PD: The Probability of default is an estimate of the likelihood of default over a given time horizon. A default may only happen at a certain time over the assessed period, if the facility has not been previously derecognized and is still in the portfolio.

LGD: The loss given default is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that the lender would expect to receive, including from the realization of any collateral.

EAD: The Exposure at default is an estimate of the exposure at a future default date, taking into account expected changes in the exposure after the reporting date, including repayments of principal and interest, whether scheduled by contract or otherwise, expected drawdown on committed facilities, and accrued interest from missed payments.

For measuring 12-month and lifetime ECL, cash shortfalls are identified as follow:

12-month expected credit losses: the portion of lifetime expected credit losses that represents the expected credit losses that result from default events on the financial instruments that are possible within the 12 months after the reporting date.

Lifetime expected credit losses: the expected credit losses that result from all possible default events over the expected life of the financial instrument.

The Bank considered a multi-factor analysis to perform credit risk analysis. The type of portfolio or transactions, industry, collaterals and monitoring basis (corporate or smaller commercial, mortgage and consumer loans).

The Bank divides its portfolio as:

Commercial loans,

ii.

Mortgage loans,

iii.

Consumer loans, and

iv.

Contingent loans

ECL allowance calculated on an Individual basis:

For financial assets in the corporate portfolio that are (a) credit-impaired at the reporting date (classified in stage 3 with a PD equal to 100%), and (b) is individually significant, the Bank calculates allowance for expected credit losses on an individual basis by using a "Cash flow discounted Methodology". In this instance, the Bank measures the expected credit losses as the difference between the asset’s gross carrying amount and the present value of estimated future cash flows discounted at the financial asset’s original effective interest rate. Any adjustment is recognized in profit or loss as an impairment gain or loss.

ECL allowance calculated on a collective basis:

Commercial loans (except for those described within the "ECL allowance calculated on an Individual basis" description aforementioned), mortgage loans and consumer loans are grouped and assessed on a collective basis by using a credit loss allowance model. The estimation of the collective basis expected credit loss allowance considers qualitative and quantitative information that may affect the changes in credit risk and the development of assumptions related to the probabilities of default and loss given default, including forward looking information, multi-factor analysis such as type of portfolio or transaction and macroeconomic factors.

Contingent loans

The Bank has entered into various irrevocable loan commitments and contingent liabilities. Even though these obligations may not be recognized on the statements of financial position, they contain credit risk and, therefore, form part of the overall risk of the Bank.

When the Bank estimates the ECL for contingent loans, it estimates the expected portion of the loan commitment that will be drawn down over its expected life.

ii.

Forward looking information

The ECL model includes a broad range of forward-looking information as economic inputs, such as:

●

GDO growth

●

Unemployment rates

●

Central Banks interest rates

●

Real estate prices

iii.

Modifications of financial assets

When loan measured at amortized cost has been renegotiated or modified but not derecognized, the Bank recognizes 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.

For ECL estimation purposes on financial assets that have been modified, is required to distinguish between modification that result in derecognition from those that does not result in derecognition. 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 derecognition, then the modified asset is considered to be a new asset. Accordingly, the date of modification is treated as the date of initial recognition for the purposes of the impairment requirements.

iv.

Collateral

The Banks seeks to use collateral to mitigate its credit risks on financial assets, where possible. Types of collateral are: cash, securities, letters of credit, real estate and inventories. The Bank’s accounting policy for collateral assigned to it through its lending arrangements under IFRS 9 is the same is it was under IAS 39. Collateral, unless repossessed, is not recorded on the Bank’s statements of financial position. However, the fair value of collateral affects the calculation of ECLs. The main collateral associated to mortgage loans are real estate, which are valued based on data provided by specialized third parties.

The estimation of ECL reflects the cash flows expected from collateral and other credit enhancement that are part of the contractual terms of the financial instruments.

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

Write-offs

The gross carrying amount of a financial asset is reduced when there is no reasonable expectation of recovery. A write-off constitutes a derecognition event of the corresponding loan transaction in its entirety, and therefore, include portions not past-due for installments loans or leasing operation (no partial write-off).

Subsequent recoveries of amounts previously written-off are credited to the income statements, as recovery of loans previously write-off, as a deduction from provisions for loan losses.

Loan and accounts receivable write-offs are recorded for overdue and current installments based on the time periods expired since reaching overdue status, as described below:

Type of loan		Term
Consumer loans with or without collateral		6 months
Other transactions without collateral		24 months
Commercial loans with collateral		36 months
Mortgage loans		48 months
Consumer leasing		6 months
Other non-mortgage leasing transactions		12 months
Mortgage leasing (household and business)		36 months

vi.

COVID-19 support measures

The COVID-19 pandemic has had a major impact on Chile and global economies. As a result, the Chilean government announced a series of measures to support lending. The largest measure was to provide additional funds to the Guarantee Fund for Small Companies (Fogape), a state fund that guarantees loans, leases and other credits provided to small businesses, extending Fogape’s coverage to companies with annual sales of up to UF 1 million and further amended the rules to encourage that banks provide lending to small businesses. Under this Fogape, domestic banks, including us, provided loans with preferential interest rates equal to the MPR plus 3% and terms of up to 48 months to eligible companies (“Fogape loans”). Such loans had a 6-month grace period before repayment is due. In addition, companies that received loans guaranteed by Fogape, were also entitled to a payment holiday for all other outstanding loans for a period of 6 months. In February 2021, the government approved the FOGAPE 2.0 – or FOGAPE Reactiva - program. The maximum rate was set at a monthly rate of TPM (overnight rate) plus 0.6%, implying an annual rate of 7.2%. The focus was to provide loans for SMEs investments and not only for working capital needs. These loans can be granted until December 31, 2021.

In 2020, the Bank in accordance with CMF’s instruction to facilitate access to credit for companies and household, provided payment holiday terms of up to three months to mortgage customers with no more 30 days past due. This was extended by a further three months for customers in need. For consumer loans, the Bank granted benefits such as a 3-month grace period to start paying, increases in terms, decreases in installments, and had even opted for lower market rates existing in 2020.

Customers who requested COVID-19 relief, including payment holidays, were not the subject of any wider SICR triggers, and did not have to be moved to Stage 2 for a lifetime ECL assessment unless they had other triggered SICR criteria. Additionally, payment holidays did not cause that such loans to become past due and therefore did not trigger a Stage 2 or Stage 3 lifetime ECL assessment.

The assessment of SICRs and the measurement of ECLs are required to be based on reasonable and supportable information that is available to an entity without undue cost or effort. The Bank has developed estimates based on the best available information about past events, current conditions and forecasts of economic conditions. During 2021, due to the continuing uncertainties caused by the new variants of COVID-19 virus and according to our corporate guidelines, our management has decided not to modify the thresholds for SICR. However, in assessing forecast conditions, the Bank has updated the macro economical forward-looking information and scenarios in 2021, increasing the ECL allowance in 2021 and releasing the overlay provision established at the end of 2020. See Note N°38, Risk management.

Use of estimates

s)	Use of estimates

The preparation of the financial statements requires the Bank’s management to make estimates and assumptions that affect the application of the accounting policies and the reported balances of assets, liabilities, revenues and expenses. Actual results may differ from these estimates.

In certain cases, International Financial Reporting Standards (IFRS) require that assets or liabilities be recorded or disclosed at their fair values. The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When available, quoted market prices in active markets have been used as the basis for measurement. When quoted market prices in active markets are not available, the Bank has estimated such values based on the best information available, including the use of modeling and other valuation techniques.

The Bank has established allowances to cover credit losses. These allowances must be regularly reviewed taking into consideration factors such as changes in the nature and volume of the loan portfolio, trends in forecasted portfolio quality, credit quality and economic conditions that may adversely affect the borrowers’ ability to pay. Increases in the allowances for loan losses are reflected as “Provision for loan losses” in the Consolidated Statements of Income. Loans are charged-off when the Bank’s management determines that a loan or a portion thereof is impaired. Charge-offs are recorded as a reduction of the allowance for loan losses.

The relevant estimates and assumptions made to calculate provisions are regularly reviewed by the Bank’s Management to quantify certain assets, liabilities, revenues, expenses, and commitments.

These estimates, made on the basis of the best available information, mainly refer to:

Allowances for loan losses

Impairment losses of certain assets

The useful lives of tangible and intangible assets

The fair value of assets and liabilities

Commitments and contingencies

Current and deferred taxes

Non-current assets held for sale (in “Other Assets”)

t)	Non-current assets held for sale (in “Other Assets”)

As of December 31, 2021 the Bank reclassified its investments on Redbanc and Transbank from Investments held-for-sale to Investments in associates, due to the lack of potential buyers as a result of the ongoing effects caused by COVID-19 pandemic, in Chile and abroad.

The requirements established in IFRS 5 to classify assets (or disposal group) as held for sale are the following:

●

the assets are available for immediate sale in its present conditions and its sale must be highly probable.

●

for the sale to be highly probable, the appropriate level of management is committed to a plan to sell the asset, and an active program to locate a buyer and complete the plan.

●

additionally, the sale should be expected to qualify for recognition as a completed sale within one year from the date of classification.

An entity shall measure a non-current asset (or disposal group) classified as held for sale at the lower of its carrying amount and fair value less sale costs.

Events or circumstances may extend the period to complete the sale beyond one year. An extension of the period required to complete a sale does not preclude an asset from being classified as held for sale if the delay is caused by events or circumstances beyond the entity’s control and there is sufficient evidence that the entity remains committed to its plan to sell the asset.

Assets received or awarded in lieu of payment

Assets received or awarded in lieu of payment of loans and accounts receivable from clients are recognized at their fair value (as determined by an independent appraisal). A price is agreed upon by the parties through negotiation or, when the parties do not reach an agreement, at the amount at which the Bank is awarded those assets at a judicial auction. In the both cases, an independent appraisal is performed. 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).

The difference between the carrying value of the asset and the estimated fair value less costs to sell is charged to net income for the period, under “Other operating expenses”. The result obtained in the sale of the asset is subsequently recorded under “Other operating income”.

Independent appraisals are obtained at least every 18 months and fair values are adjusted accordingly. No adjustments have been made between appraisals with respect to the period covered by these financial statements considering the stability of the real estate market in Chile during past years and expected stability of the real estate market in the coming years.

At least once a year, the Bank performs the necessary analysis to update the “cost to sale” of assets received or awarded in lieu of payments. According to the Bank’s survey, as of December 31, 2021 the average cost to sale was estimated at 4.0% of the appraisal value (3.2% as of December 31, 2020).

Temporary acquisition (assignment) of assets and liabilities

v)	Temporary acquisition (assignment) of assets and liabilities

Purchases or sales of financial assets under non-optional repurchase agreements at a fixed price are recorded in the Consolidated Statements of Financial Position based on the nature of the debtor (creditor) under “Deposits in the Central Bank of Chile,” “Deposits in financial institutions” or “Loans and accounts receivable from customers” (“Central Bank of Chile deposits,” “Deposits from financial institutions” or “Customer deposits”), in Note 7.

Differences between the purchase and sale prices are recorded as financial interest over the term of the contract.

Provision for mandatory dividends

w)	Provision for mandatory dividends

As of December 31, 2021, 2020 and 2019 the Bank recorded a provision for mandatory dividends. This provision is made pursuant to Article 79 of the Corporations Act, which is in accordance with the Bank’s internal policy, pursuant to which at least 30% of net income for the period is distributed, except in the case of a contrary resolution adopted at the respective shareholders’ meeting by unanimous vote of the outstanding shares. This provision is recorded, as a deducting item, under the “Retained earnings – provision for mandatory dividends” line of the Consolidated Statements of Changes in Equity with offset to Provisions.

Post-employment benefits – Defined Benefit Plan:

According to current collective labor agreements and other agreements, the Bank has an additional benefit available to its principal executives, consisting of a pension plan whose purpose is to endow them with funds for a better supplementary pension upon their retirement.

Features of the Plan:

The main features of the Post-Employment Benefits Plan promoted by the Banco Santander-Chile are:

Aimed at the Bank’s management.

The general requirement to apply for this benefit is that the employee must be carrying out his/her duties when turning 60 years old.

The Bank will create a pension fund, with life insurance, for each beneficiary in the plan. Periodic contributions into this fund are made by the manager and matched by the Bank.

The Bank will be responsible for granting the benefits directly.

The Bank uses the method of projected unit credit, to determine the present value of the defined benefit obligation and the current service cost.

Components of defined benefit cost include:

current service cost and any past service cost, which are recognized in profit or loss for the period;

net interest on the liability (asset) for net defined benefit, which is recognized in profit or loss for the period;

new liability (asset) remeasurements for net defined benefit include:

(a)

actuarial gains and losses;

(b)

the difference between the actual return on plan assets and the interest on plan assets included in the net interest component and;

(c)

changes in the effect of the asset ceiling.

The liability (asset) for net defined benefit is the deficit or surplus, determined as the difference between the present value of the defined benefit obligation less the fair value of plan assets.

Plan assets comprise the pension fund taken out by the Group with a third party that is not a related party. These assets are held by an entity legally separated from the Bank and exist solely to pay benefits to employees.

The Bank recognizes the present service cost and the net interest of the Personnel salaries and expenses on the Consolidated Statements of Income.

The post-employment benefits liability, recognized in the Consolidated Statements of Financial Position represents the deficit or surplus in the defined benefit plans of the Bank. Any surplus resulting from the calculation is limited to the present value of any economic benefits available in the form of refunds from the plan or reductions in future contributions.

When employees leave the plan before meeting the requirements to be eligible for the benefit, contributions made by the Bank are reduced.

ii.

Cash-settled share-based compensation

The Bank allocates cash-settled share-based compensation to executives of the Bank and its Subsidiaries in accordance with IFRS 2. The Bank measures the services received and the obligation incurred at fair value. Until the obligation is settled, the Bank determines the fair value at the end of each reporting period, as well as at the date of settlement, recognizing any change in fair value in the income statements of the period.

Market risk trading portfolio, description	For the Bank, the VaR estimate is made under the historical simulation methodology, which consists of observing the behavior of the profits and losses that would have occurred in the current portfolio if the market conditions for a given historical period had been in force, in order to infer the maximum loss on the basis of that information, with a given degree of confidence. The methodology has the advantage of precisely reflecting the historical distribution of the market variables and not requiring any assumptions regarding the distribution of specific probabilities. All the VaR measures are intended to determine the distribution function for a change in the value of a given portfolio, and once that distribution is known, to calculate the percentile related to the necessary degree of confidence, which will be equal to the value at risk by virtue of those parameters. As calculated by the Bank, the VaR is an estimate of the maximum expected loss of market value for a given portfolio over a 1–day horizon, with a 99.00% confidence level. It is the maximum 1–day loss that the Bank could expect to experience in a given portfolio, with a 99.00% confidence level. In other words, it is the loss that the Bank would expect to experience only 1.0% of the time. The VaR provides a single estimate of market risk which is not comparable from one market risk to another. Returns are calculated through the use of a 2–year time window or at least 520 data points obtained since the last reference date for calculation of the VaR going backward in time.

Liquidity, description	In response to the COVID-19 pandemic, the Chilean Central Bank established two credit lines for banks to reinforce their liquidity: The first is the Credit Facility Conditioned to Increase of Loans (FCIC1), whose objective was for banks to continue financing households and companies’ loans. The FCIC1 amounted to US$24 billion for the whole banking system and have maturities of up to 4 years and must be secured by government bonds, corporate bonds or highly rated large commercial loans as collateral. The FCIC2 amounted US$16 billion and was available only for banks who must have previously drawn upon FCIC1. The FCIC3 was announced in January 2021 and amounted to US$10 billion. The second credit line was the Liquidity Credit line (LCL) and it was an unsecured loan facility that had maturities of up to 2 years. In addition, the LCL was limited to the aggregate amount of the liquidity reserve requirements of each bank. As of December 31, 2021, and 2020, we had borrowed Ch$5,611,439 and Ch$4,959,260, respectively, under these lines of credit.
Capital adequacy requirement, description	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 FMC 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, 2021, the ratio of our regulatory capital to risk-weighted assets, net of loan loss allowance and deductions under BIS I, was 14.49% and our core capital ratio was 5.72%. 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,
Percentage of basic capital	8.00%

NON CURRENT ASSETS HELD FOR SALE

NOTE 39

NON CURRENT ASSETS HELD FOR SALE

Banco Santander decided to implement its own acquiring network, and therefore the Bank decided to sell the participation in the companies that provided those services. At that time, the Bank classified investment in Redbanc and Transbank as held-for-sale and senior management was engaged in an active program to locate buyers.

In accordance with facts and circumstances arising from the social unrest in Chile and the global pandemic due to COVID-19 (situations beyond the Bank’s control), and the absence of suitable buyers, the process of selling its equity has failed. According to the above, our management has re-evaluated the situation and decided to reclassify the stakes as Investment in associates. See Note 12.

As of December 31, 2020, the Bank has sold its participation in Nexus.

Fogape's annual sales, description	The largest measure was to provide additional funds to the Guarantee Fund for Small Companies (Fogape), a state fund that guarantees loans, leases and other credits provided to small businesses, extending Fogape’s coverage to companies with annual sales of up to UF 1 million and further amended the rules to encourage that banks provide lending to small businesses. Under this Fogape, domestic banks, including us, provided loans with preferential interest rates equal to the MPR plus 3% and terms of up to 48 months to eligible companies (“Fogape loans”). Such loans had a 6-month grace period before repayment is due. In addition, companies that received loans guaranteed by Fogape, were also entitled to a payment holiday for all other outstanding loans for a period of 6 months. In February 2021, the government approved the FOGAPE 2.0 – or FOGAPE Reactiva - program.
