The Interim Consolidated Financial Statements are referred as of March 31, 2021 and December 31, 2020 and comprise the three month periods ended March 31, 2021 and 2020.

Notes to the Interim Consolidated Financial Statements (unaudited)
As of March 31, 2021 and December 31, 2020 and for the three-month periods ended March 31, 2021 and 2020

Note 1 - General Information and Summary of Significant Accounting Policies, continued

International Accounting Standards Board (IASB). If there are discrepancies between IFRS and the accounting criteria set forth in the CAS, the latter will prevail.

Additionally, these Interim Consolidated Financial Statements in relation to the application of IAS 34 'Interim Financial Information', are prepared mainly with the intention of updating the content of the latest Annual Consolidated Financial Statements, emphasizing new activities, events and circumstances occurred during the nine-month periods ended March 31, after the end of the year, and not duplicating the information previously published in the last Consolidated Financial Statements.

As a result, these Interim Consolidated Financial Statements do not include all the information that a complete set of Financial Statements prepared in accordance with the international accounting and financial information standards agreed by the IASB would require, so for an adequate understanding of the information included in these Interim Consolidated Financial Statements, these must be read in conjunction with the Annual Consolidated Financial Statements, corresponding to the immediately preceding annual period.

Notes to these Interim Consolidated Financial Statements contain information additional to that disclosed in the Interim Consolidated Statements of Financial Position, Interim Consolidated Statements of Income, Interim Consolidated Statements of Other Comprehensive Income, Interim Consolidated Statements of Changes in Equity, and Interim Consolidated Statements of Cash Flows. On them descriptive information and disaggregated information is presented.

c)Consolidation criteria

These Interim Consolidated Financial Statements comprise the preparation of the separate (individual) Financial Statements of the Bank and the controlled entities which participate in consolidation as of March 31, 2021 and December 31, 2020 and for the three month periods ended March 31, 2021 and 2020 included in the Interim Consolidated Financial Statements, and include necessary adjustments and reclassifications to standardize the accounting policies and valuation criteria applied by the Bank, in accordance with standards established in the Compendium of Accounting Standards issued by the CMF.

Intercompany balances and any unrealized income or loss arising from intercompany transactions are eliminated upon consolidation during the preparation of the Interim Consolidated Financial Statements.

For consolidation purposes, the financial statements of the branch in New York have been converted into Chilean pesos at the exchange rate of $720.19 for US$1 as of March 31, 2021 ($853.82 as of March 31, 2020 and $710.73 as of December 31, 2020), same situation for Colombian subsidiaries using an exchange rate of $0.1962 for COP $1 as of March 31, 2021 ($0.2111 as of March 31, 2021 and $0.2078 as of December 31, 2020), in accordance with IAS 21 'Effects of variations in foreign currency exchange rates', relations with the valuation of investments abroad in countries with economic stability.

Assets, liabilities, income, and results of operations of subsidiaries, net of consolidation adjustments, represent 18%,19%,29%, and 22%, respectively, of total consolidated assets, liabilities, income, and operating results as of March 31, 2021 (18% and 19% as of December 31, 2020 of total assets and liabilities; 28% and 17% as of March 31,2020, of income, and results of operations, net of consolidation adjustments).

(i)	Controlled entities

The Bank, regardless of the nature of its involvement with an entity (the investee), shall determine whether it is a parent by assessing whether it controls the investee.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

The Bank controls an investee when it is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee.

Thus, the Bank controls an investee if and only if has all the following:

1)	Power over the investee, which is related to the existing rights that give the Bank the current ability to direct the relevant activities, these being those that significantly affect the investee's returns;

2)	Exposure, or rights, to variable returns from its involvement with the investee;

3)	Ability to use its power over the investee to affect the amount of the Bank's returns;

When the Bank has less than a majority of the voting rights over an investee, but such voting rights are sufficient to have the actual ability to direct the relevant activities, then it will be concluded that the Bank has control over the investee.

The Bank considers all relevant factors and circumstances when assessing if the voting rights are sufficient to obtain control, these include:

●	The amount of voting rights held by the Bank in relation to the amount and dispersion of those held by other vote holders.

●	Potential voting rights held by the Bank, other voting holders or other parties.

●	Rights that arise from other contractual agreements.

●	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 those decisions need to be made, including the patterns of voting behavior in previous shareholders meetings.

The Bank reassesses whether or not it has control over an investee when facts and circumstances indicate that there are changes in one or more of the control elements listed above.

The interim financial statements of the controlled companies are consolidated with those of the bank through the global integration method (line by line). In accordance with this method, all balances and transactions between consolidated companies are eliminated through the consolidation process. Therefore, the Interim Consolidated Financial Statements refer to assets, liabilities, equity, income, expenses, and cash flows of the parent and its subsidiaries presented as if they were a single economic entity. The Bank prepares Consolidated Financial Statements using uniform accounting policies for transactions and other events that, being similar, have occurred in similar circumstances.

(ii)	Associated entities and/or business support

Associated entities are those over which the Bank has significant influence, although not control or joint control. If the Bank holds, directly or indirectly (e.g. through subsidiaries), 20% or more of the voting power of the investee, it is presumed that the Bank has significant influence, unless it can be clearly demonstrated that this is not the case, and subsequently increased or decreased to recognize either the Bank's proportional share in the net profit or loss of the associate and other movements recognized in its equity. The lower value arising from the acquisition of an associate is included in the book value of the investment net of any accumulated impairment loss.

Other factors considered to determine the significant influence on an entity are the representations in the Board of Directors and the existence of material transactions. The existence of these factors could determine the existence of significant influence on an entity, despite having a participation of less than 20% of the shares with the right to vote.

The following entities are considered 'Associated entities', in which the Bank has participation and are accounted for by applying the equity method, according to IAS 28 'Investments in Associates and Joint Ventures':

Associates	As of March 31, 2021	As of December 31, 2020
name	Principal activity	Place of incorporation	% participation	% participation
Nexus S.A.	Credit and debit card operator	Santiago, Chile	14.8148	%	14.8148	%
Transbank S.A.	Credit card operator	Santiago, Chile	8.7188	%	8.7188	%

Itaú Corpbanca exercises significant influence by virtue of its voting right to appoint a representative in the Board of Directors. This, among other business considerations, led the Administration to conclude that Itaú Corpbanca has significant influence over the aforementioned entities.

(iii)

Investments in other companies

Investments in other companies, represented by shares or rights in other companies, are those in which the Bank has neither control nor significant influence. These investments are recorded at cost, and adjustments for impairment losses are recorded when appropriate.

(iv)	Funds management, trust business and other related businesses

The Bank and its subsidiaries manage assets held in publicly offered investment funds and other investment vehicles on behalf of investors and receive market-rate compensation for providing this type of services. Managed funds belong to third parties and, therefore, are not included in the Interim Consolidated Statement of Financial Position.

The Bank provides trust commissions and other fiduciary services that result in the participation or investment of assets by clients. Assets held in a fiduciary activity are not reported in the Interim Consolidated Financial Statements, since they are not Bank assets and there is no control over them. Contingencies and commitments arising from this activity are disclosed in Note 23 'Contingencies, Commitments, and Responsibilities', letter d), related to Responsibilities recorded in off-balance sheet accounts.

In accordance with IFRS 10 'Consolidated Financial Statements,' for consolidation purposes, the role of the Bank and its subsidiaries with respect to the managed funds must be evaluated to determine whether it is acting as Agent or Principal. According to this standard, an Agent is a party primarily engaged in acting on behalf and for the benefit of another party or parties (the Principal or Principals) and, therefore, it does not control the investee when it exercises decision-making authority. This evaluation must consider the following aspects:

●Scope of its decision-making authority over the investee.

●Rights held by other parties

●The remuneration to which it is entitled to in accordance with the remuneration agreements.

●	Decision-maker's exposure to variability of returns from other interests that it holds in the investee.

The Bank does not control or consolidate any trusts or other entities related to this type of business.

The Bank manages the funds on behalf and for the benefit of investors, acting solely as an Agent. The assets managed by the Bank and its subsidiaries are owned by third parties. Under this category, and in accordance with the aforementioned standard, they do not control the assets when they exercise their decision-making authority. Therefore, as of March 31, 2021 and 2020, and December 31, 2020 they act as Agent and none of these investment vehicles is consolidated.

(v)	Joint Operation

An entity shall determine the type of joint arrangement in which it is involved. The classification of a joint arrangement as a joint operation or a joint venture depends upon the rights and obligations of the parties to the arrangement.

The Bank shall recognise in relation to its interest in a joint operation its assets, liabilities, revenue and expenses.

d)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 Interim Consolidated Statement of Income, and separately from shareholders' equity in the Interim Consolidated Statement of Financial Position.

Additionally, the non-controlling interests in the Interim Consolidated Statements of Financial Position will be presented, within the equity under item 'Non-controlling interest', separately from the equity attributable to owners of the Bank. Changes in the ownership interest of a parent in a subsidiary that do not result in a loss of control are equity transactions (i.e., transactions with owners in their capacity as owners).

The Bank attributes the result of the period and each component of other comprehensive income to the owners of the Bank and to the non-controlling interests. The Bank also attributes the total integral result to the owners of the Bank and to the non-controlling interests even if the results of the non-controlling interests give rise to a debit balance.

e)Use of estimates and judgments

The preparation of the Interim Consolidated Financial Statements requires Bank's management to make estimates, judgments and assumptions that affect the application of the accounting policies and the reported balances of assets and liabilities, disclosures of contingencies with respect to assets and liabilities as of the date of the Interim Consolidated Financial Statements, as well as income and expenses during the period. Actual results may differ from these estimates.

Estimates and relevant assumptions are regularly reviewed by Management in order to properly measure some assets, liabilities, income, and expenses. Accounting estimates changes due to reviews are recognized in the period in which the estimate is reviewed and in any future period affected.

In certain cases, the regulator standards and International Financial Reporting Standards require that assets and liabilities be recorded or disclosed at their fair values. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction in the principal (or most advantageous) market at the measurement date under current market conditions (i.e. an exit price) regardless of whether that price is directly observable or estimated using another valuation technique. When market prices in active markets are available, they have been used as a basis for valuation. When market prices in active markets are not available, the Bank has estimated those values as values based on the best available information, including the use of modeling and other valuation techniques.

The Bank has established allowances to cover possible credit losses in accordance with the CAS. These regulations require that, in order to estimate allowances, they be evaluated regularly, taking into account factors such as changes in the nature and size of the loan portfolio, trends in the expected portfolio, credit quality and economic conditions that may affect the payment capacity of the debtors. Changes in allowances for loan losses are reflected as 'Provision for loan losses' in the Interim Consolidated Statement of Income for the year.

Loans are charged-off when the Bank's management determines that the loan or a portion cannot be collected, this in accordance with the regulatory dispositions issued by the CAS, as stated in chapter B-2 'Impaired loans and charge-offs'. Charge-offs are recorded as a reduction of the allowance for loan losses.

In particular, information on most significant areas of estimate due to uncertainties and critical judgments in the application of accounting policies that have the most important effect on the amounts recorded in the Interim Consolidated Financial Statements are the following:

●Allowances for loan losses (Notes 9, 10, and 29).

●Fair value of financial assets and liabilities (Note 34).

●Contingencies and commitments (Note 23).

●Impairment losses of certain assets, including goodwill (Notes 9, 10, 13, 14, 15, 29 and 32).

●Current taxes and deferred taxes (Note 16).

During the period ended March 31, 2021, with exception of goodwill, there have been no significant changes in estimates made at the end of 2020 (see Note 32).

f)Classifications of financial instruments

(i)	Classification of financial assets for measurement purposes

Financial assets are classified into the following specified categories: 'trading investments', 'held to maturity investments', 'available for sale investments' and 'loans and accounts receivable from customers'. The classification depends on the nature and purpose of the financial assets and is determined at the time of initial recognition.

Financial assets are initially recognized at fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs that are directly attributable to the acquisition or issue.

Measurement criteria for financial assets recorded in the Interim Consolidated Statement of Financial Position, are as follows:

Financial assets measured at amortized cost

Amortized cost is the acquisition cost of a financial asset or liability, plus or minus, as appropriate, prepayments of principal and the cumulative amortization (recorded in the Interim Consolidated Statement of Income) of the difference between the initial cost and the maturity amount as calculated under the effective interest method. For financial assets, amortized cost also includes any reductions for impairment or uncollectibility.

The 'effective interest rate' is the discount rate that exactly matches the initial amount of a financial instrument to all its estimated cash flows over its remaining life. For fixed-rate financial instruments, the effective interest rate incorporates the contractual interest rate established on the acquisition date plus, where applicable, the fees and transaction costs that are a part of the financial return are included. For floating-rate financial instruments, the effective interest rate matches the current rate of return until the date of the next review of interest rates.

The effective interest rate includes all commissions and other items paid or received that are part of the effective interest rate. Transaction costs include incremental costs that are directly attributable to the acquisition of a financial asset.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

Financial assets measured at fair value

According to IFRS 13 'Fair Value Measurement', 'fair value' is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction in the principal (or most advantageous) market at the measurement date under current market conditions (i.e. an exit price) regardless of whether that price is directly observable or estimated using another valuation technique.

Fair value is a market-based measurement, not an entity specific measurement. For some assets and liabilities, observable market transactions or market information might be available. For other assets and liabilities, observable market transactions and market information might not be available. However, the objective of a fair value measurement in both cases is the same - to estimate the price at which an orderly transaction to sell the asset or to transfer the liability would take place between market participants at the measurement date under current market conditions (i.e. an exit price at the measurement date from the perspective of a market participant that holds the asset or owes the liability).

When a price for an identical asset or liability is not observable, an entity measures fair value using another valuation technique that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs. Because fair value is a market-based measurement, it is measured using the assumptions that market participants would use when pricing the asset or liability, including assumptions about risk.

Between valuation techniques are included the use of recent market transactions to sell the asset or to transfer the liability between market participants at the measurement date, references to the fair value of other substantially identical financial instrument, discounted cash flows and option pricing models. Consistent with this, the Bank's intention to keep and asset or to sell, dispose or satisfy a liability is not relevant when estimating fair value.

When determining fair value an entity shall consider the characteristics of the asset or liability if market participants would take those characteristics into account when pricing the asset or liability at the measurement date.

To increase consistency and comparability in fair value measurements and related disclosures, IFRS 13 establishes a fair value hierarchy that categorizes into three levels the inputs to valuation techniques used to measure fair value. The fair value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (level 1 inputs) and the lowest priority to unobservable inputs (level 3 inputs). Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity can access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.

In those rare cases when fair value cannot be reasonably estimated for a financial asset or liability, this is measured at its amortized cost.

Additionally, in accordance to what is indicated in Chapter A-2 'Limitations or clarifications to the use of general criteria' of the Compendium of Accounting Standards, banks cannot designate financial assets or liabilities at fair value as an option instead of using the general criteria of amortized cost.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

The Interim Consolidated Financial Statements have been prepared using the general criteria of amortized cost, except for:

●	Financial derivatives contracts measured at fair value.

●	Available for sale investments measured at fair value through other comprehensive income.

●	Trading investments measured at fair value.

●	Financial assets and liabilities under hedge accounting relationships which allow them to be measured at fair value.

Trading investments

Financial assets are classified as held for trading when they have been acquired mainly for the purpose of selling them in the near term and on initial recognition are part of a portfolio of identified financial instruments that the Bank manages together and have a recent actual pattern of short-term profit-taking.

Trading investments are measured at fair value according to market quotes or by using valuation techniques at the closing date. Any gains or losses arising on remeasurement are recognized in profit or loss. The net gain or loss recognized in profit or loss incorporates any dividend or interest earned on the financial asset and is included in the 'Net income (expense) from financial operations' line item in the Interim Consolidated Statements of Income.

Held to maturity investments

Held to maturity investments are non-derivative financial assets with fixed or determinable payments and fixed maturity dates that the Bank has the positive intent and ability to hold to maturity. Any other investment instrument is classified as available for sale.

Investment instruments are initially recorded at cost, which includes transaction costs. Subsequent to initial recognition, held-to-maturity investments are measured at amortized cost using the effective interest method less any impairment.

Available for sale investments

The category of instruments available for sale includes those instruments that are not classified as trading instruments or as held to maturity.

Available for sale investments are subsequently measured at fair value according to market prices or valuation obtained by using valuation techniques, less impairment losses. Unrealized gains and losses originated as a consequence of fair value changes are recorded in valuation accounts within equity. When these investments are disposed or impaired, the recorded amount in equity is transferred to income and is reported under 'Net income (expenses) from financial operations'.

Interest and inflation-indexation adjustments of investments held to maturity and of instruments available for sale are included in 'Interest income' in the Interim Consolidated Statement of Income.

Investment instruments that are treated as hedged items in hedge accounting transactions relationships are adjusted according to the rules applicable to hedge accounting.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

Purchases and sales of investment instruments that shall be delivered o settled within the term established by market regulations or conventions are recognized at the trading date when the purchase or sale of the instrument is agreed. Investment instruments are assessed at the end of each reporting period to timely identify impairment indication which may result in losses.

Investment instruments must be permanently assessed to timely identify impairment indication which may result in losses which are recorded in the Interim Consolidated Statement of Income as 'impairment'.

The Bank has assessed its investments portfolio classified as 'Held to maturity investments' and 'Available for sale investments' in order to identify if there is objective evidence of impairment. Such assessment includes economic analysis, risk ratings for the issuers, and Management's ability and intent to hold those investments until maturity. Based on the Management's evaluation of these investments it is concluded that no impairment indication exists.

Loans and accounts receivables from customers and interbank loans

Loans and accounts receivables from customers and interbank loans, originated and purchased, are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market and for which the Bank has no intention to sell them immediately or in the short term, They are measured at amortized cost using the effective interest method, less any impairment determined according to the CAS.

Financial derivative contracts

Financial derivative contracts, which include foreign currency and Unidades de Fomento (UF) forwards, interest rate futures, currency and interest rate swaps, currency and interest rate options and other financial derivative instruments are initially recognized in the Interim Consolidated Statement of Financial Position at their fair value (including transaction costs), which is usually their acquisition cost, and subsequently measured at their fair value.

The fair value is obtained from corresponding market pricings, discounted cash flows models and pricing valuation models. The derivative instruments are recognized as an asset when their fair value is positive and as a liability when they are negative in 'Financial derivative contracts' in the Interim Consolidated Statement of Financial Position. Additionally, the Credit Valuation Adjustment and Debit Value Adjustment is included as part of the fair value for each instrument, all that with the objective of properly reflect the counterparty and own risk in the fair value measurement.

Certain derivatives embedded in other financial instruments are treated as separate derivatives when their risks and characteristics are not closely related with those of the host contract and when such host contracts are not measured at fair value through profit or loss.

At inception of a derivative agreement, the Bank must designate it either as a derivative instrument for trading or for hedge accounting purposes. However, in some circumstances, the Bank can subsequently designate a derivative from the trading derivatives portfolio as a hedging instrument if the requirements for hedge accounting set in IAS 39, are met.

Changes in the fair value of derivative instruments held for trading are included in 'Net income (expenses) from financial operations' in the Interim Consolidated Statement of Income.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

If the derivative instrument is classified as hedging instrument for hedge accounting purposes, the hedge can be:

1)	A fair value hedge of existing assets or liabilities or a 'commitment' to be executed

2)	cash flow hedge of existing assets or liabilities or forecast transactions

3)	A net investment in foreign operations hedge, as defined by IAS 21

A hedging relationship qualifies for hedge accounting if, and only if, all of the following conditions are met:

1)	At the inception of the hedge there is formal designation and documentation of the hedging relationship;

2)	the hedge is expected to be highly effective;

3)	the effectiveness of the hedge can be reliably measured, and;

4)	the hedge is assessed on an ongoing basis and determined to have actually been highly effective throughout the financial reporting periods for which the hedge was designated.

Certain transactions with derivatives that do not qualify for being classified as hedging derivatives are treated and recognized as trading derivatives, even when they provide effective economic hedges of the risk positions.

When a derivative hedges the exposure to changes in the fair value of an existing item of the asset or liability, such hedged item is measured at fair value from the designation of the fair value hedge until its expiration in connection with the specific hedged risk. Fair value adjustments for both the hedged item and the hedging instrument are recognized in the Interim Consolidated Statements of Income.

If the hedged item in a fair value hedge is a firm commitment, the changes in the fair value of the firm commitment regarding the hedged risk are recognized as assets or liabilities with effect on the Interim Consolidated Statement of Income for the period. Gains or losses from the changes in fair value measurement of the hedging derivative are recognized with effect on the Interim Consolidated Statements of Income for the period. When a new asset or liability is acquired as a result of the firm commitment, the initial recognition of the acquired asset or liability is adjusted to incorporate the accumulated effect of the fair value valuation of the firm commitment recognized in the Interim Consolidated Statement of Financial Position.

When a derivative instrument hedges the exposure to changes in the cash flows of existing assets or liabilities, or forecast transactions, the effective portion of changes in the fair value related to the hedged risk is recognized in other comprehensive income and accumulated valuation accounts within equity. The cumulative loss or gain in cash flows hedge recorded in valuation accounts is transferred to the Interim Consolidated Statement of Income to the extent that the hedged item impacts income because of the hedged risk, offsetting the effect in the same line item of the Interim Consolidated Statement of Income. Any ineffective portion is directly recognized in the Interim Consolidated Statement of Income.

In case of a fair value hedge of interest rate risk of a portfolio with the hedged item representing currency value instead of individual assets or liabilities, gains or losses from the fair value measurement for both the hedged item and the hedging instrument, are recognized in the Interim Consolidated Statement of Income, but the fair value adjustment of the hedged portfolio is presented in the Interim Consolidated Statement of Financial Position under the 'Other assets' or 'Other liabilities' items, depending on the hedged portfolio balance as of the reporting date.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

Financial asset and liability balances are offset, i.e., reported in the Interim Consolidated Statement 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.

(ii)	Classification of financial assets for presentation purposes

For presentation purposes, financial assets are classified by their nature into the following line items:

-

Cash and deposits in banks: This item comprises cash, checking accounts and demand deposits at the Central Bank of Chile and other financial institutions in Chile and abroad. The amounts invested in overnight deposits will continue to be reported under this heading and in the corresponding lines or items.

-	Cash items in process of collection: this item represents domestic transactions in the process of transfer through a central domestic clearinghouse or international transactions which may be delayed in settlement due to timing differences, etc.

-	Trading investments: this item includes financial instruments held-for-trading and investments in mutual funds which must be adjusted to their fair value in the same way as instruments acquired for trading.

-

Financial derivative contracts: financial derivative contracts with positive fair values are presented in this item. It includes both independent contracts as well as derivatives that should and can be separated from a host contract, whether they are held for trading or designated as hedging instruments in hedge accounting relationships, as disclosed in Note 8 to the Consolidated Financial Statements.

-	Interbank loans: this item includes balances of transactions with domestic and foreign banks, including the Central Bank of Chile, other than those reflected in other financial asset classifications listed above.

-	Loans and accounts receivables from customers: these loans are non-derivative financial assets for which fixed or determined amounts are charged, that are not listed on an active market and for which the Bank has no intention to sell them immediately or in the short term.

-

Investment instruments: are classified into two categories: held-to-maturity investments, and available-for-sale investments. The held to maturity investment category includes only those instruments for which the Bank has the ability and intent to hold to maturity. The remaining investments are treated as available for sale.

(iii)

Classification of financial liabilities for measurement purposes

Financial liabilities are generally measured at amortized cost, except for those financial liabilities designated as hedged item (or as hedge instruments) and liabilities held for trading, which are measured at fair value. Financial liabilities are classified as either financial liabilities at FVTPL or other financial liabilities.

Financial liabilities at fair value through profit and loss: As of March 31, 2021 and December 31, 2020 the Bank does not maintain financial liabilities at FVTPL other than financial derivative contracts.

Other financial liabilities: Other financial liabilities (including interbank borrowings, issued debt instruments and other accounts payables) are initially recorded at fair value and subsequently measured at amortized cost using the effective interest method.

(iv)	Classification of financial liabilities for presentation purposes

Financial liabilities are classified by their nature into the following line items in the Interim Consolidated Statements of Financial Position:

-

Deposits and other demand liabilities: this item includes all on-demand obligations except for term savings accounts, which are not considered demand instruments in view of their special characteristics. Obligations whose payment may be required during the period are deemed to be on-demand obligations. Operations which become callable the day after the closing date are not treated as on-demand obligations.

-	Cash items in process of being cleared: this represents domestic transactions in the process of transfer through a central domestic clearing house or international transactions which may be delayed in settlement due to time differences, etc.

-	Obligations under repurchase agreements: this includes the balances of sales of financial instruments under securities repurchase and loan agreements. The Bank does not record in its own portfolio instruments acquired under repurchase agreements.

-	Time deposits and other time liabilities: this item includes balances of deposit transactions in which a term at the end of which they become callable has been stipulated.

-	Financial derivative contracts: this includes financial derivative contracts with negative fair values (i.e. a liability of the Bank), whether they are designated for trading or for hedge accounting purposes, as set forth in Note 8.

-	Interbank borrowings: this item includes obligations with other domestic banks, foreign banks, or the Central Bank of Chile, other than those reflected in certain other financial liability classifications listed above.

-	Issued debt instruments: there are three types of instruments issued by the Bank: Obligations under letters of credit, Subordinated bonds and senior bonds placed in both local and foreign markets.

-	Other financial liabilities: this item includes credit obligations with entities other than domestic banks, foreign banks, or the Central Bank of Chile, for financing purposes or operations in the normal course of business.

g)Leases

On the date of commencement of a lease the Bank recognizes an asset for right of use and a liability for lease in accordance with the provisions of IFRS 16 'Leases'.

(i)	Assets for-right-of-use

At the beginning of a lease, the right-of-use asset is measured at cost. The cost includes (a) the amount of the initial measurement of the lease liability; (b) lease payments made before or from the start date, less lease incentives received; (c) the initial direct costs incurred by the lessee; and (d) a modification of the costs to be incurred by the lessee when dismantling and eliminating the underlying asset, restoring the place in which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease.

After the initial recognition date, the Bank measures the assets by right of use applying the cost model, which is defined as the asset by right of use measured at cost (a) less accumulated depreciation and accumulated risk losses of value; and (b) adjusted for any new measurement of the lease liability.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

The Bank applies the depreciation requirements established by IAS 16 'Property, plant and equipment' over the right-of-use in these types of transactions.

If the lease transfers ownership of the underlying asset to the Bank at the end of the lease term or if the cost of the right-of-use asset reflects that the Bank will exercise a purchase option, the Bank will depreciate the right-of-use asset from commencement date to the end of the useful life of the underlying asset. In another case, the Bank will depreciate the right-of-use asset from commencement to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term, whichever comes first.

The Bank applies IAS 36 'Impairment of Assets' to determine whether the right-of-use asset is impaired and to account for any impairment loss identified.

As of March 31, 2021, the Bank has not identified impairment in the value of the right of use assets.

(ii)	Liability for lease

The Bank measures the lease liability at the present value of lease payments that have not been paid as of that date. Lease payments are discounted using the interest rate implicit in the lease, if that rate could be easily determined. Since that rate cannot be easily determined, the Bank uses the incremental rate for loans (cost of funding).

The lease payments included in the measurement of the lease liability determined the payments for the right of use the underlying asset during the term of the not cancelable lease at the measurement date which includes (a) fixed payments, less any lease incentive receivable (b) variable lease payments, which depends on an index or rate, recently measured using the index or rate on the start date; (c) it matters that the lessee expects to pay as residual value guarantees; (d) the exercise price of a purchase option if the lessee is reasonably sure to exercise that option; and (e) payments for penalties arising from the termination of the lease, if the term of the lease reflects that the lessee exercises an option to terminate the lease.

After the date of initial recognition, the Bank measures the lease liability in order to recognize (a) the interest on the lease liability; (b) lease payments made; and (c) the new measurements or modifications of the lease, and also for fixed lease payments that have essentially been reviewed.

The Bank makes new measures of the lease liability discounting the modified lease payments, if (a) there is a change in the expected amounts payable related to a residual value guarantee. A lessee will determine the lease payments to determine the change in the amounts expected to be paid under the residual value guarantee; (b) there will be a change in future lease payments determined from a change in an index or a rate used to determine those payments. The Bank measures the lease liability again to modify the modified lease payments only when there is a change in cash flows. The Bank will determine the revised lease payments, for the remainder of the lease term, based on the revised contractual payments.

As of January 1, 2019, the Bank measured the lease liability at the present value of the lease payments discounted using the incremental interest rate for loans (cost of funding).

h)Allowances for loan losses

The Bank has established allowances to cover the incurred and expected losses of certain financial assets that have been determined in accordance with the regulations and instructions set forth by the CMF and models and methodologies based on individual and collective analysis of the borrowers, approved by the Board of Directors with the aim of establishing in a timely manner allowances required and sufficient enough to cover incurred and expected losses based on risk characteristics of debtors and their loans that determine the payment behavior and subsequent collection.

Processes and policies compliance are evaluated and supervised according to the established internal control procedures with the purpose of ensuring its compliance and an adequate level of allowances to cover expected and incurred losses.

Individual assessment of borrowers is performed when the customer, due to its size, complexity or exposure, is required to be identified and analyzed on an individual basis. Collective assessment is used for a large number of transactions with homogeneous characteristics, for small amounts which relate to individuals or small size entities.

In order to establish allowances for loan losses, an assessment of the loans and contingent loans portfolios is performed as indicated below:

●	Individual allowances for the normal portfolio.

●	Individual allowances for the substandard portfolio.

●	Individual allowances for the non-compliant portfolio.

●	Group allowances for the normal portfolio.

●	Group allowances for the non-compliant portfolio

(i)	Individual allowances

When a debtor is considered as individually significant, i.e. with significant levels of debt and for those ones that are not significant but cannot be classified in groups of financial assets with homogeneous credit risk characteristics, and due to its size and complexity or exposure it is required to be individually assessed.

The methodology used to classify and determine its allowances is performed in accordance with Chapter B-1 'Provisions for credit risk' from the CAS, assigning risk categories to each debtor according to the following detail:

Normal portfolio

It corresponds to debtors whose capacity payments allows them to comply with their obligations and commitments, and according to the economic-financial situation this condition will not changes. The classifications assigned to this portfolio are the categories that goes from A1 to A6. Notwithstanding the above, the Bank must maintain a minimal allowance percentage of 0.5% over its loan portfolio and contingent loans that form part of the Normal portfolio.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

Substandard portfolio

The substandard portfolio includes the borrowers which have financial difficulties, or whose payment capacity worsened significantly, presenting reasonable doubt regarding the probability to collect the principal and interest under the contractually agreed terms, indicating that they are less likely to comply with their financial obligations in the short term. In addition, borrowers that recently held loans in default for over 30 days also are included in the substandard portfolio. The classifications assigned to this portfolio are categories B1 to B4.

Normal and Substandard portfolios

As part of the debtors' individual analysis, the Bank classifies its debtors into the aforementioned categories, assigning probabilities of default (PD) and loss given default (LGD), which yield the expected loss percentages as a result. These variables are regulated by the CMF to be applied to each of the individual categories.

Below are presented the probabilities of default and loss given default, as established by the CMF:

Debtor	Probability of default	Loss given default	Expected loss
Type of portfolio	category	(PD)	(LGD)	(EL)
(%)	(%)	(% allowance)
A1	0.04	90.00	0.03600
A2	0.10	82.50	0.08250
Normal portfolio	A3	0.25	87.50	0.21875
A4	2.00	87.50	1.75000
A5	4.75	90.00	4.27500
A6	10.00	90.00	9.00000
B1	15.00	92.50	13.87500
B2	22.00	92.50	20.35000
Substandard portfolio	B3	33.00	97.50	32.17500
B4	45.00	97.50	43.87500

In order to determine the amount of allowance to be established, the first step is to determine the net exposure which is comprised of loans and receivables plus loan commitments, less the amount to be recovered by collateral execution and then the corresponding expected losses percentages are applied. The Bank must demonstrate that the collateral value considered as an exposure deduction reasonably reflects the value that the collateral would have when disposed. The credit risk category of the debtor is substituted by the credit risk category of the guarantor only if the guarantor is an entity with a credit risk classification corresponding to an investment grade or higher, granted by a national or international classification agency approved. In any case the guaranteed values may be deducted from the exposure amount. The procedure applies only in the case of financial or real guarantees.

Non-compliant portfolio

Non-compliant portfolio includes the loans to borrowers for which recovery is considered remote, given that they have suffered a loss event resulting in impairment. This portfolio includes borrowers with evident signs of possible bankruptcy, as well as those in which a forced debt renegotiation is required, and also includes any borrower with loans in default for equal to or greater than 90 days in the payment of interest or principal of any loan. This portfolio includes borrowers classified under categories C1 to C6 in the classification scale established below and classification is assigned to the debtor's portfolio at the classification at the riskiest level, including 100% of the loan commitments that those borrowers maintain.

In calculating allowances for the non-compliant portfolio, loss rate percentages are used, which must be applied to the exposure, corresponding to the sum of loans and receivables and loan commitments held by the same borrower. In order to apply this percentage, an expected loss rate must be estimated first, deducting from the exposure the amounts expected to be recovered by execution of collateral and, in the case of having solid data that justifies them, deducting also the net present value of expected recoveries that can be obtained by the execution of actions to collect, net of expenses associated with these actions.

That loss rate must be classified into one of the nine categories defined according to the range of losses effectively expected by the Bank for all the operations of an individual borrower

Allowance percentages to be applied over the exposition are as follows:

Type of portfolio	Risk scale	Expected loss range	Allowance
C1	Up to 3%	2%
C2	More than 3% and up to 20%	10%
C3	More than 20% and up to 30%	25%
Non-compliant portfolio	C4	More than 30% and up to 50%	40%
C5	More than 50% and up to 80%	65%
C6	More than 80%	90%

Loans are kept in this category until there is observable evidence to conclude that the capacity and payment behavior is back to normal, regardless of charging-off loans that comply with the conditions established in the accounting policy indicated in letter t) 'Impaired loans and charge-offs', charge-off section (title II of Chapter B-2 of the Compendium of Accounting Standards).

To remove a debtor from this portfolio, once the circumstances that made it be classified in this category are overcome, all the following requirements must be met, in a copulative manner:

1)	None of the debtor obligations with the Bank are overdue for more than 30 days.

2)	No new re-financing of loans has been granted.

3)	At least one of the payments received includes principal payment (total or partial).

4)	If the debtor has a loan with partial payments due within six months, two payments have been made.

5)	If the debtor has to pay monthly installments for one or more loans, at least four consecutive installments have been paid.

6)	The debtor shows no direct unpaid debts in the consolidated information provided by the CMF, unless those debts are not material.

(ii)	Group allowances

Collective assessment is used to deal with a large number of loan transactions with small amounts granted to individuals and small size companies. This type of assessment, as well as the criteria to apply them, must be consistent with those used when loans were granted.

To establish allowances, collective assessment requires grouping loans with homogeneous characteristics in terms of type of debtor and loan conditions, in order to conform by technically formulated methodologies and following prudential criteria, the payment behavior of the group and the recoveries for defaulted loans.

Based on the above, the groups are assigned with a probability of default (PD) and loss given default (LGD) considering the profile that best suits the loan. Net exposure is calculated, which includes the book value of the loan plus contingent loans.

Standard method for mortgage loans allowances

For the purposes of calculating credit risk provisions of the mortgage loan portfolio for housing, the Bank recognizes the higher amount of provision resulting from using the internal model and the standard provision method for mortgage loans established in the CAS. According to this method the provision factor to be applied, represented by the expected loss (EL) over the amount of the mortgage loans, depends on the overdue of each loan and the relation, at the end of each month, between the gross exposure and the corresponding collateral (LTV), according to the following table:

Number of overdue	Default
LTV range	days	0	1 - 29	30 - 59	60 - 89	portfolio
PI (%)	1.0916	21.3407	46.0536	75.1614	100
LTV ≤ 40%	PDI (%)	0.0225	0.0441	0.0482	0.0482	0.0537
PE (%)	0.0002	0.0094	0.0222	0.0362	0.0537

PE (%)	0.0421	0.7745	1.5204	2.3047	3.0413
PI (%)	2.5150	27.9300	52.5800	79.6952	100
80% < LVT ≤ 90%	PDI (%)	21.5527	21.6600	21.9200	22.1331	22.2310
PE (%)	0.5421	6.0496	11.5255	17.6390	22.2310
PI (%)	2.7400	28.4300	53.0800	80.3677	100
LVT > 90%	PDI (%)	27.2000	29.0300	29.5900	30.1558	30.2436
PE (%)	0.7453	8.2532	15.7064	24.2355	30.2436

In case the same debtor has more than one mortgage loan with the Bank and one of those loans is 90 days overdue or more all those loans are incorporated to the Non-compliant portfolio, calculating allowances for each one of those loans applying the corresponding percentage according to the LTV.

Note 1 - General Information and Summary of Significant Accounting Policies, continued

For mortgage loans related to housing programs and benefits from the Government, when guaranteed by the corresponding auction insurance, the allowance percentage could be weighted for a loss mitigating factor, which depends on the LTV percentage and the value of the property at inception. The loss mitigating factors are those shown in the table below:

MP factor of mitigation of losses for credits with state
Range LTV	insurance of auction
Section V: Deed price of the house (UF)
V ≤ 1,000	1,000 < V ≤ 2,000
LTV ≤ 40%	100%	100%
40% < LTV ≤ 80%	100%	100%
80% < LTV ≤ 90%	95%	96%
LTV > 90%	84%	89%

Provisions for commercial loans

For this type of loan, the Bank recognizes the higher provision resulting from the internal models and standard models established in the CAS. The applicable percentages of provision and the parameters used to determine the provision, are set out on the CAS.

●	Commercial leasing operations

The allowance is determined based on the book value of the commercial lease operations (including the purchase option). The allowance percentage used in the calculation will depend on the delinquency of each operation, the type of leased asset and the relationship, at the end of each month, between the book value of each operation and the value of the leased asset (LTV), as indicated in the following tables:

Probability of Default (PD) applicable according to delinquency and type of asset (%)
Days in arrears of the operation at	Type of leased assets
the end of the month	Real estate	Non-real estate
0	0.79	1.61
1-29	7.94	12.02
30-59	28.76	40.88
60-89	58.76	69.38
Non-compliant portfolio	100.00	100.00

Loss Given Default (LGD) applicable according to LTV range and type of asset (%)
LTV= Book value/Value of the leased asset
LTV range	Real estate	Non-real estate
LTV <= 40%	0.05	18.20
40% < LTV <= 50%	0.05	57.00
50% < LTV <= 80%	5.10	68.40
80% < LTV <= 90%	23.20	75.10
LTV > 90%	36.20	78.90

The LTV relationship is determined considering the guarantee appraisal value, expressed in UF for real estate and in Chilean pesos for non-real estate, recorded at inception, considering any transitory event that may cause an increase on the value of the asset.

●	Student loans

The expected loss (%) is applied over the amount of the student loan and the exposure of the contingent credit when applicable. The factor used is determined based on the type of student loan and the collectable payment of principal or interest, at the end of each month. Only when payment is due, the factor will also depend on overdue.

●	Generic commercial placements and factoring

Factoring operations and commercial loans, other than those indicated above, the expected loss (%) is applied over the amount of the loan and on the exposure of the contingent credit. The factor used is determined based on whether the operation has guarantees and it's overdue. In addition, for those operations with guarantees, the relationship between the debtor´s obligations to the bank and the value of the guarantees (LTV) is used to determine the factor as indicated in the following tables:

Probability of Default (PD) applicable according to delinquency and LTV range (%)

debtors). For the purposes of calculating the LTV, the invoices assigned in the factoring operations, nor the guarantees associated with mortgage loans can be considered.

The guarantees used in calculating the LTV relationship may be of a specific or general purpose, including those that are simultaneously specific and general. For specific guarantees, the LTV ratio must be calculated independently for each guaranteed transaction. For general and specific guarantees, LTV is determined as the division between the sum of the amounts of the loan and exposures of contingent credits and the general, or general and specific guarantees considering any restriction.

Non-compliant portfolio - Collectively assessed loans

Non-compliant portfolio includes all loans and contingent loans of a borrower that presents an overdue equal to or more than 90 days in the payment of interest or principal in any of its loans. It will also include borrowers who renegotiated a loan with more than 60 days overdue and borrower who have been subject to a forced debt renegotiation.

The chapter requires banking institutions to publish an independent document, referring exclusively to pillar 3.

On October 28, 2010 its revised version is published, agreeing guidelines on the classification and measures of financial liabilities. On November 19, 2013, see an amendment which includes the new general hedge accounting model. On July 24, 2014, the IASB issued the final version of IFRS 9, which contains the accounting requirements for financial instruments, replacing IAS 39 'Financial Instruments: Recognition and Measurement'.

The standard establishes the following requirements:

Classification and Measurement: Financial assets are to be classified based on the business model in which they are held and the characteristics of their contractual cash flows. The 2014 version of IFRS 9 introduces a measurement category called 'fair value with change in other comprehensive income' for certain debt instruments. Financial liabilities are classified in a manner similar to IAS 39 'Financial Instruments: Recognition and Measurement', however, there are differences in the requirements applicable to the measurement of the entity's own credit risk.

Impairment: The 2014 version of IFRS 9 introduces an 'expected credit loss' model for the measurement of impairment of financial assets, so it is not necessary for an event related to the credit to occur before the recognition of the credit losses.

Hedge accounting: Introduces a new model that is designed to align hedge accounting more closely with risk management, when they cover exposure to financial and non-financial risk.

Derecognition of accounts: The requirements for derecognition of financial assets and liabilities keep the existing requirements of IAS 39 'Financial Instruments: Recognition and Measurement'.

IFRS 9 is effective for annual periods beginning on or after January 1, 2018. Early adoption is permitted.

Amendment to IFRS 9 'Financial instruments'

Published on October 17, 2017, this modification allows more assets to be measured at amortized cost in the previous version of IFRS 9, in particular some prepaid financial assets with negative compensation.

To qualify at amortized cost, the negative compensation must be a 'reasonable compensation for early termination of the contract.'

Amendment toIAS 28 'Investments in associates and joint ventures'

On October 12, 2017, the IASB published Long-Term Participations in Associates and Joint Ventures (Amendments to IAS 28). The amendments clarify that IFRS 9, including its change requirements, involves long-term participation. In addition, when applying IFRS 9 to long-term interests, an entity does not take in the measurement of adjustments to its book values ​​required by IAS 28 (that is, adjustments to the book value of long-term shares that originate from the allocation of investment losses or evaluation of the reduction in accordance with IAS 28).

The retrospectively affected amendments sometimes annual that began on or after January 1, 2019. Early application is allowed. The specific transitional provisions specific to the application for the first time of the amendments coincide with that of IFRS 9.

With the issuance of the New Compendium of Accounting Standards for Banks (CASB), IFRS 9 should be applied only in those sections where the regulator allows it.

2.2)	Sale or Contribution of assets between an investor and its Association or Joint Business (amendments to IFRS 10 and IAS 28)

The amendments to IFRS 10 and IAS 28 address situations where there is a sale or contribution of assets between an investor and its associate or joint venture. Specifically, the amendments provide that gains or losses, resulting from the loss of control of a subsidiary that does not contain a business in a transaction with an associate or joint venture, accounted for using the equity method are recognized in the parent's profit or loss only to the extent of the unrelated investors' interests in that associate or joint venture. Similarly, gains or losses resulting from the remeasurement to fair value of investments held in a former subsidiary (which has become an associate or joint venture that is accounted for using the equity method) are recognized in the results of the former parent only to the extent of the unrelated investors' interests in the new associate or joint venture.

The effective date of the amendments was initially from January 1, 2016, however the IASB on December 17, 2015 indefinitely postponed their entry into force.

Management will evaluate the potential impacts of these amendments, once the new date to be implemented is determined on these amendments.

2.3)	Amendment to IAS 1 'Presentation of Financial Statements' - Classification of liabilities as current or non-current

On January 23, 2020, the IASB published the amendment to IAS 1, which addresses the classification of liabilities and clarifies their presentation as current or non-current. This amendment applies as of January 1, 2023 retroactively and its early application is permitted.

Among the modifications are the following:

• An entity shall classify a liability as current when it does not have a right to postpone its liquidation for at least twelve months following the date of the reporting period. The amendment removes the factor of 'unconditionality' from this right.

• The right to defer settlement of the liability must have substance and must exist at the end of the reporting period. If this right is subject to the entity that covers any condition, such right only exists if it is effectively fulfilled by fulfilling these conditions at the end of the reporting period and can be classified as non-current. The entity must comply with these conditions, although the counterparty does not carry out a testing of these.

• The classification of the liability will not be affected by the probability that the entity exercises its right to defer its settlement. Therefore, if the liability meets the non-current condition specified in the standard, it will be classified as non-current, even if the entity plans to liquidate it in less than 12 months from the period in which it is reported or between the periods in which it is reported. And the one that is reported to the regulator. If any of the above cases occurs, it must be disclosed in the Financial Statements to understand the impact of the entity's financial position.

• The liability is understood as liquid when the entity extinguishes the obligation to control its effective counterparty, other economic resources, or its own equity instruments.

The adoption of this amendment will not have a material impact on the Interim Consolidated Financial Statements. The Bank must present its financial statements in accordance with the regulatory framework set out on section II.3 of Chapter C-1, Financial Statements annual, of the CAS, which presents the Statement of Financial Situation that the Bank must use, therefore, this amendment will not affect the preparation of the factors affected by the entity.

The changes in Reference to the Conceptual Framework (Amendments to IFRS 3):

-	update IFRS 3 so that it refers to the 2018 Conceptual Framework instead of the 1989 Framework;

-	add to IFRS 3 a requirement that, for transactions and other events within the scope of IAS 37 or IFRIC 21, an acquirer applies IAS 37 or IFRIC 21 (instead of the Conceptual Framework) to identify the liabilities it has assumed in a business combination; and

-	add to IFRS 3 an explicit statement that an acquirer does not recognize contingent assets acquired in a business combination.

The amendments published are effective for annual periods beginning on or after 1 January 2022. Early application is permitted if an entity also applies all other updated references (published together with the updated Conceptual Framework) at the same time or earlier.

The adoption of the amendment will not have material impacts on the Interim Consolidated Financial Statements.

2.5)	Amendments to IAS 16 'Property, Plant and Equipment - Proceeds before Intended Use

On May 14, 2020, the IASB published amendments to IAS 16 regarding proceeds from selling items produced while bringing an asset into the location and condition necessary for it to be capable of operating in the manner intended by management.

Amends the standard to prohibit deducting from the cost of an item of property, plant and equipment any proceeds from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the cost of producing those items, in profit or loss.

The Bank's Management is currently evaluating the potential impact of the adoption of these amendments in its Interim Consolidated Financial Statements.

2.6)	Amendments to IAS 37 'Onerous Contracts - Cost of Fulfilling a Contract

On May 14, 2020, the IASB published 'Onerous Contracts - Cost of Fulfilling a Contract (Amendments to IAS 37) amending the standard regarding costs a company should include as the cost of fulfilling a contract when assessing whether a contract is onerous.

The changes in Onerous Contracts - Cost of Fulfilling a Contract (Amendments to IAS 37) specify that the 'cost of fulfilling' a contract comprises the 'costs that relate directly to the contract'. Costs that relate directly to a contract can either be incremental costs of fulfilling that contract (examples would be direct labor, materials) or an allocation of other costs that relate directly to fulfilling contracts (an example would be the allocation of the depreciation charge for an item of property, plant and equipment used in fulfilling the contract).

The amendments published today are effective for annual periods beginning on or after 1 January 2022. Early application is permitted.

2.7)	Annual improvements to IFRS standards 2018-2020

On May 14, 2020, the IASB published Annual Improvements to IFRS Standards 2018-2020 makes amendments to the following standards:

IFRS 1 First-time Adoption of International Financial Reporting Standards - Subsidiary as a first-time adopter. The amendment permits a subsidiary that applies paragraph D16(a) of IFRS 1 to measure cumulative translation differences using the amounts reported by its parent, based on the parent's date of transition to IFRSs.

IFRS 9 Financial Instruments- Fees in the '10 per cent' test for derecognition of financial liabilities. The amendment clarifies which fees an entity includes when it applies the '10 per cent' test in paragraph B3.3.6 of IFRS 9 in assessing whether to derecognize a financial liability. An entity includes only fees paid or received between the entity (the borrower) and the lender, including fees paid or received by either the entity or the lender on the other's behalf.

IFRS 16 Leases - Lease incentives. The amendment to Illustrative Example 13 accompanying IFRS 16 removes from the example the illustration of the reimbursement of leasehold improvements by the lessor in order to resolve any potential confusion regarding the treatment of lease incentives that might arise because of how lease incentives are illustrated in that example.

IAS 41 Agriculture - Taxation in fair value measurements. The amendment removes the requirement in paragraph 22 of IAS 41 for entities to exclude taxation cash flows when measuring the fair value of a biological asset using a present value technique. This will ensure consistency with the requirements in IFRS 13.

The amendments to IFRS 1, IFRS 9, and IAS 41 published today are all effective for annual periods beginning on or after 1 January 2022. Early application is permitted.

The amendment to IFRS 16 only regards an illustrative example, so no effective date is stated.

The Bank's Management is currently evaluating the potential impact of the adoption of these amendments in its Interim Consolidated Financial Statements.

c.	Other operating cash flows

Based on the nature of its activities, the Bank considers that its funding has a direct relationship with its loan and investing portfolio; for such purpose all those activities are taken into consideration to determine, approve and monitor the financial strategies that guide the Bank with respect to the composition of its assets and liabilities, cash inflows and outflows and transactions with financial instruments.

Finally, the Bank, based on its overall business strategy, considers that gains and losses derived from these transactions are part of the main revenue generating activities and core business, and that the presentation of the cash flows from those items under operating activities consequently shows consistency between our Interim Consolidated Statement of Income and our Interim Consolidated Statement of Cash Flows.

Examples of cash flows from operating activities are:

(i) Investments under resale agreements and obligations under repurchase agreements. These items represent the cash flows (collections and payments) corresponding to the purchase and sale of obligations and securities lending associated with financial intermediation activities (see Note 7).

(ii) Investments portfolio. This item represents the cash flows (collections and payments) of our trading and non-trading portfolio related financial instruments (see Note 6 and Note 11).

(iii) Foreign borrowings and repayment of foreign borrowings. These items represent the cash flows (collections and payments) of obligations with foreign banks (see note 19) for the financing of foreign trade loans, which are included as part of the following items: 'Loans and receivables from banks' (see Note 9) and 'Loans and receivables from customers' (see Note 10).

(iv) Increase and repayment of other borrowings. These items represent the cash flows (collections and payments) arising from the obligations corresponding to financing or operations specific to the business (see Note 20).

d)Impairment

Itaú Corpbanca evaluates, at the end of each reporting period, whether there is any indication of impairment of any asset (including Goodwill). If this indication exists, or when an impairment test is required, the Bank estimates the recoverable amount of the asset.

As a result of the evaluation of the impairment indicators, as of June 30, 2020, the impairment test was carried out on the valuation of Goodwill and the intangibles generated in business combinations assigned to CGUs Chile and Colombia.

The outcome of the impairment test, concluded that it was necessary to recognize in the Interim Consolidated Financial Statements as of June 30, 2020, an impairment loss associated with the Goodwill assigned to the Chile CGU for Ch$448,273 million, a loss for Ch$246,663 million corresponding to the total of Goodwill assigned to the Colombia CGU and a loss of Ch$113,911 million (Ch$79,364 million net of deferred taxes) that represents all of the intangibles generated in business combinations assigned to the Colombia CGU. The total impact of these effects on the result attributable to the Bank's owners amount to Ch$764,024 million and Ch$10,276 million corresponding to non-controlling interest. This was reported on July 9, 2020 to the Commission for the Financial Market and recognized in the Interim Financial Statements as of June 30, 2020.

Lastly, due to the merger of the financial institutions, Itaú Corpbanca has used systems to manage its operations of both entities, in order to eliminate the duplication of systems and generate efficiencies, the bank has established an integration plan. In relation to this process, during 2020 the migration of the surviving systems was substantially completed, and impairment as of December 31, 2020 for MCh $ 38,849 has been recognized, affecting those systems and licenses that do not will continue to be used.

As of March 31, 2021, no indications of impairment have been identified that affect the balances of intangibles.

c) Impairment

Since the COVID-19 health emergency, the Bank accelerated its digital transformation as a means to take care of both its customers and workforce. For this purpose, processes have been digitized, so that its clients may access its products and make use of the various services provided by the Bank from its digital platform. The Bank adopted remote working as a means to minimize the exposure of its workforce to COVID-19. One of the main effects of the pandemic has been the preference of the Bank's clients to use digital channels over performing in-person transactions in its branches, which has led to a decrease in the flow of clients in certain branches. As a result, the Bank has initiated a restructuring plan in order to improve efficiency, closing branches that have lower customer demand. The plan also contemplates the closure of certain offices, given the Bank's adoption of remote working.

Within the framework of the aforementioned restructuring plan, during this fiscal year, the Bank has recognized the impairment of certain assets associated with branches and offices that were closed during fiscal year 2020.

Other adjustments (*)	0.60	732	0.75	702
Effective tax rate	24.32	29,476	70.34	65,560

(*)This item contains the effects due to changes in the observed US dollar exchange rate in the valuation of the investment in the New York branch for tax purposes and other effects.

(**)These items reflect differences in tax rates of other jurisdictions, based on the Bank's consolidated result.

(***)During the three-month period ended March 31, 2021, the inflation indexation adjustments over the Tax Equity was equal to 1.2% (1.1% in 2020).

(****) For tax purposes, investment in Colombia is measured in US dollars. The devaluation (appreciation) of the Chilean peso against the US dollar generates income (expenses) for tax purposes and not recognized for financial purposes. The value presented represents the expense (income) of income tax due to the effect of the exchange rate on investment in Colombia. As part of its exchange rate risk management policy, the Bank has managed this exposure through instruments available in the market to economically protect it against the variation in the exchange rate. The effect of the instruments (which compensates the tax effect here presented) is recognized in the Net foreign exchange gain (loss) on the Interim Consolidated Statement of Income for the period.

Note 23 - Contingencies, Commitments, and Responsibilities

a)	Lawsuits and Legal Proceedings

Lawsuits against the Bank with provision

As of the date of issuance of these Interim Consolidated Financial Statements, legal actions have been filed against the Bank and its subsidiaries involving its transactions in the ordinary course of business. They are mainly lawsuits pending against the Bank related to loans and other matters, most of which, according to the Bank's Legal Services Divisions involved in the suits, present no risk of significant loss. Notwithstanding the above, provisions for Ch$237 million as of March 31, 2021 and Ch$545 million as of December 31, 2020, respectively have been established in the Interim Consolidated Financial Statements.

Other lawsuits in Chile against the Bank without provision

There are other legal actions filed against the Bank in relation to the operations of the business. The Bank's maximum exposure for these lawsuits amounts to approximately Ch$23,619 million as of March 31, 2021 and Ch$22,737 million as of December 31, 2020. However, Management's opinion based on reports from the Legal Division as of March 31, 2021, it is more likely than not that these lawsuits will not result in significant losses not contemplated by the Bank in these Interim Consolidated Financial Statements, so there are no provisions established for them.

Itaú Corpbanca Colombia S.A.

The Bank and its subsidiaries are involved in civil, administrative and labor proceedings. The outstanding civil and administrative proceedings, them are related to banking transactions, and the remaining ones derive from the ownership of leased assets.

Such claims amount, in the aggregate, to Ch$34,767 million as of March 31, 2021 (Ch$35,043 million as of December 2020). According to the evaluation of the expected results in each lawsuits the Bank has recorded a provision of Ch$90 million as of March 31, 2021 (Ch$94 million as of December 31, 2020).

b.Impairment

As of March 31, 2021 and 2020, no impairment was recorded.

Itaú Corpbanca evaluates, at the end of each reporting period, whether there is any indication of impairment of any asset (including Goodwill). If this indication exists, or when an impairment test is required, the Bank estimates the recoverable amount of the asset.

The Bank has defined two CGUs: CGU Chile (Itaú Corpbanca and its Chilean subsidiaries and the New York branch) and CGU Colombia (Itaú Corpbanca Colombia and its subsidiaries and Itaú Corredor de Seguros S.A.). These CGUs were defined based on their main geographic areas. Their cash flow generation and performance are analyzed separately by Top management because their contributions to the consolidated entity may be identified independently. It is worth mentioning that these CGUs are consistent with the Bank's operating segments (see Note 4).

Note 33 - Related Party Transactions

In accordance with the provisions set forth in the Chilean General Banking Law and the instructions issued by the Chilean Superintendency of Banks and Financial Institutions, related parties are those individuals or corporations related to the ownership or management of the Institution directly or through third parties.

Article 89 of the Ley de Sociedades Anónimas (Chilean Companies Law), which also applies to Banks, establishes that any transaction with a related party must be carried out on an arm's length basis.

In the case of publicly traded companies and their subsidiaries, transactions with related parties involve any negotiation, act, contract or transaction in which the company must intervene; the following are considered as parties related to them: those entities of the corporate group to which the company belongs; the corporations that, with respect to the company, have the status as parent, controlling entity, affiliate, subsidiary; the Directors, Managers, Administrators, Chief Executive Officer or Liquidators of the company, acting in their own names or on behalf of individuals other than the company, and their respective spouses or their relatives up to the second degree of consanguinity, as well as any entity controlled either directly or indirectly, through any of them; and any person who either acting individually or jointly with others with whom it has executed a joint operation agreement, may appoint at least one member of the management of the company or controls 10% or more of its capital stock, with the right to vote, in the case of a sociedad por acciones (stock corporation); those established by the bylaws of the company, or justifiably identified by the Directors' Committee; and those in which it has acted as Director, Manager, Administrator, Chief Executive Officer or Liquidator of the company, during the last eighteen months. Article 147 of the Ley de Sociedades Anónimas (Chilean Companies Law) sets forth that a sociedad anónima abierta (publicly traded company) may only carry out transactions with related parties when they are intended to contribute to the corporate interest, are adjusted in the price, terms and conditions to those prevailing in the market at the time of their approval and comply with the requirements and the procedure indicated by it. Moreover, Article 84 of the Chilean General Banking Law establishes limits for the loans that may be granted to related parties and the prohibition to grant loans to the Directors, Managers or General Attorneys of the Bank.

Note 34 - Fair Value of Financial Assets and Liabilities

This disclosure was prepared based on the application of the local regulatory guidelines stated in Chapter 7-12 'Fair value of financial instruments' of the CMF and IFRS 13 'Fair value measurement'. These standards have been applied to both financial assets and non-financial assets measured at fair value (recurring and non-recurring).

The following section details the main guidelines and definitions used by the Group:

Fair value: 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 (i.e. an exit price). The transaction is carried out in the principal³or most advantageous⁴market and is not forced, that is, it does not consider factors specific to the Group that may influence a real transaction.

Market participants:Buyers and sellers in the principal (or most advantageous) market for the asset or liability that have all of the following characteristics:

(i)

They are independent of each other, i.e. they are not related parties as defined in IAS 24 'Related Party Disclosures', although the price in a related party transaction may be used as an input to a fair value measurement if the entity has evidence that the transaction was entered into at market terms.

(ii)	They are knowledgeable, having a reasonable understanding about the asset or liability and the transaction using all available information, including information that might be obtained through due diligence efforts that are usual and customary.

(iii)

They are able to enter into a transaction for the asset or liability.

(iv)	They are willing to enter into a transaction for the asset or liability (i.e. they are motivated, but not forced or otherwise compelled, to do so).

Fair value measurement. When measuring fair value, the Group takes into account the same characteristics of the asset or liability that market participants would consider in pricing that asset or liability on the measurement date.

Aspects of the transaction. A fair value measurement assumes that the asset or liability is exchanged in an orderly transaction between market participants to sell the asset or transfer the liability at the measurement date under current market conditions. The measurement assumes that the transaction to sell the asset or transfer the liability takes place: (a) on the principal market for the asset or liability; or (b) in the absence of a principal market, on the most advantageous market for the asset or liability.

Market participants. The fair value measurement measures the fair value of the asset or liability using the assumptions that the market participants would use in pricing the asset or liability, assuming that the participants act in their best economic interest.

Prices. Fair value is the price that will be received for the sale of an asset or paid for the transfer of a liability in an orderly transaction on the main (or most advantageous) market as of the measurement date under current market conditions (i.e. exit price) regardless of whether that price is directly observable or estimated using another valuation technique.

³ The market with the greatest volume and level of activity for the assets or lialility.

⁴ The market that maximizes the amount that would be received to sell the asset or minimizes the amount that would be paid to transfer the liability, after taking into account transaction costs and transport costs.

Note 34 - Fair Value of Financial Assets and Liabilities, continued

Highest and best use of non-financial assets. The fair value measurement of these assets takes into account the market participant's ability to generate economic benefits through the highest and best use of the asset or through the sale of the asset to another market participant that would maximize the value of the asset.

Group's own liabilities and equity instruments. The fair value measurement assumes that these items are transferred to a market participant on the date of measurement. The transfer of these items assumes that:

(i)	A liability would remain outstanding and the market participant transferee would be required to fulfill the obligation. The liability would not be settled with the counterparty or otherwise extinguished on the measurement date.

(ii)	An entity's own equity instrument would remain outstanding and the market participant transferee would take on the rights and responsibilities associated with the instrument. The instrument would not be canceled or otherwise extinguished on the measurement date.

Default risk. The fair value of a liability reflects the effect of the default risk. This risk includes, but is not limited to, the entity's own credit risk. This risk is assumed to be the same before and after the liability is transferred.

Initial recognition. When an asset is acquired or a liability assumed in an exchange transaction involving that asset or liability, the transaction price is the price paid to acquire the asset or received to assume the liability (the entry price). In contrast, the fair value of the asset or liability is the price received to sell the asset or paid to transfer the liability (the exit price). Entities do not necessarily sell assets at the prices paid to acquire them. Likewise, they do not necessarily transfer liabilities at the price received to assume them.

Valuation techniques. The Bank will use techniques that are appropriate for the circumstances and for which sufficient data is available to measure the fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. The following approaches deserve mention. The first two are the most frequently used by the Group:

(i)	Market approach. Uses prices and other relevant information generated by market transactions involving identical or comparable (similar) assets, liabilities, or a group of assets and liabilities (e.g. a business).

(ii)

Income approach. Converts future amounts (cash flows or income and expenses) to a single current (discounted) amount, reflecting current market expectations about those future amounts. The fair value measurement is determined based on the value indicated by the current market expectations about those future amounts.

(iii)

Cost approach. Reflects the amount that would be required currently to replace the service capacity of an asset (current replacement cost).

Present value techniques. Technique to adjust the discount rate and expected cash flows (expected present value). The present value technique used to measure the fair value will depend on the specific facts and circumstances of the asset or liability being measured and the availability of sufficient data.

Note 34 - Fair Value of Financial Assets and Liabilities, continued

Components of the present value measurement. Present value is the tool used to link future amounts (e.g. cash flows or values) to a present amount using a discount rate. A fair value measurement of an asset or a liability using a present value technique captures all the following elements from the perspective of market participants at the measurement date:

(i)	An estimate of future cash flows for the asset or liability being measured.

(ii)	Expectations about possible variations in the amount and timing of the cash flows representing the uncertainty inherent in the cash flows.

(iii)

The temporary value of money, represented by the rate on risk-free monetary assets that have expiration dates or duration that coincides with the period covered by the cash flows and do not raise uncertainty in the temporary distribution or risk of default for the holder (that is, risk-free interest rate).

(iv)	The price to bear the uncertainty inherent in the cash flows (i.e., a risk premium).

(v)	Other factors that market participants would take into account in these circumstances.

(vi)	For a liability, the credit risk related to that liability, including the entity's own credit risk (i.e. the debtor's).

Fair value hierarchy. It gives the highest priority to quoted prices (unadjusted) in active markets for identical assets and liabilities (Level 1 inputs) and lowest priority to unobservable inputs (Level 3 inputs). Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

In addition, the fair value estimates presented above do not attempt to estimate the value of the Group's profits generated by its business, nor future business activities, and, therefore, do not represent the value of the Group as a going concern.

The following section describes the methods used to estimate fair value:

Cash, short-term assets and short-term liabilities

The fair value of these items approximates their book value given their short-term nature. These items include:

●	Cash and deposits in banks

●	Cash in the process of collection

●	Investments under agreements to resell

●	Checking accounts and demand deposits

●	Other financial obligations

Loans

The fair value of loans is determined using a discounted cash flow analysis. In the case of mortgage loans and consumer loans, the cash flows were discounted by using the effective average placement rate of the last month of the reporting period for each type of product. The fair value of commercial loans is determined using a discounted cash flow analysis, using a risk-free interest rate adjusted for expected losses from debtors based on their credit quality. The credit risk adjustment is based on variables observable in the market and the Group's policies for qualitative and quantitative credit risk methodologies.

This methodology was applied to:

●	Interbank loans

●	Loans and accounts receivable from customers

Held to maturity investments

The estimated fair value of these financial instruments is determined using quotes and transactions observed in the main market for identical instruments, or in their absence, for similar instruments. Fair value estimates of debt instruments or securities representative of debt take into account additional variables and inputs to the extent that they apply, including estimates of prepayment rates and the credit risk of issuers.

Medium and long-term liabilities

The fair value of medium and long-term liabilities is determined using a discounted cash flow analysis, using an interest rate curve that reflects current market conditions at which the entity's debt instruments are traded. Medium and long-term liabilities include:

●	Time deposits and saving accounts

●	Interbank borrowings

●	Debt instruments issued

Financial instruments

The estimated fair value of these financial instruments is determined using quotes and transactions observed in the main market for identical instruments, or in their absence, for similar instruments. Fair value estimates of debt instruments or securities representative of debt take into account additional variables and inputs to the extent that they apply, including estimates of prepayment rates and the credit risk of issuers. These financial instruments are classified as follows:

●Trading investments

●Available for sale investments

Financial derivative contracts

The estimated fair value of derivative instruments is calculated using prices quoted in the market for financial instruments with similar characteristics. Therefore, the methodology recognizes the own credit risk and the credit risk of each counterparty. The adjustment is known internationally as counterparty risk adjustment, which is composed of CVA (Credit Value Adjustment) and DVA (Debit Value Adjustment), the sum of both risk adjustments the effective counterparty risk that must be recognized. This adjustment is periodically recorded in the financial statements.

As of March 31, 2021, the portfolio of derivative contracts both in Chile and Colombia have an aggregate net effect of MCh$23,169(MCh$40,382 as of December 31, 2020), of CVA and DVA adjustments.

c)	Fair value hierarchy

IFRS 13 establishes a fair value hierarchy that classifies assets and liabilities based on the characteristics of the data that the technique requires for its valuation.

●

Level 1

Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Entity can access at the measurement date. The inputs needed to value the instruments in this category are available daily and used directly.

In the case of currency, shares and mutual funds, prices are observed directly in over-the-counter markets and the stock exchange. These prices correspond to the values at which the exact same assets are traded. As a result, the portfolio valuation does not require assumptions or models of any type.

For instruments issued by the Chilean Central Bank and the Chilean Treasury, benchmark prices are used. Benchmark prices are defined using similar durations, type of currency and are traded the equivalent of every day. The valuation of these instruments is identical to the valuation of the Santiago Stock Exchange, which is a standard international methodology. This methodology uses the internal rate of return to discount the instrument's cash flows.

●

Level 2

The specific instrument does not have daily quotes. However, similar instruments can be observed (e.g. same issuer, different maturity; or different issuer, same maturity and risk rating). In general, they are diverse combinations of pseudo-arbitration. Although the inputs are not directly observable, observable inputs are available with the needed periodicity.

In this category, instruments are valued by discounting contractual cash flows based on a zero-coupon curve determined through the price of instruments with similar characteristics and a similar issuer risk. The income approach is used, which converts future amounts to present amounts.

For derivative instruments within this category, quotes from over-the-counter transactions reported by the most important brokers in the Chilean market and the Bloomberg platform are used. The inputs observed include forward prices, interest rates and volatilities. Based on these inputs, market curves are modeled. They are a numerical representation of the opportunity costs of the instrument's cash flows or the price volatility of an asset. Finally, cash flows are discounted.

The Black and Scholes model is used for options based on prices of brokers in the OTC market.

For money market instruments, prices of transactions on the Santiago Stock Exchange are observed and used to model market curves.

For corporate or bank bonds, given the lack of market depth, the Bank uses transactions (if any) in the Chilean market, on foreign markets, zero-coupon curves of risk-free instruments, adjustment curves, spread modeling, correlation with similar financial instruments, etc. and gives market curves as the final result. These market curves are provided by a pricing supplier and are widely accepted by the market, regulators and scholars.

●

Level 3

This is used when prices, data or necessary inputs are not directly or indirectly observable for similar instruments for the asset or liability as of the valuation date. These fair value valuation models are subjective in nature. Therefore, they base their estimate of prices on a series of assumptions that are widely accepted by the market. The Group has two products in this category:

Due to the lack of liquidity in the basis of the active banking rate (TAB) over the chamber rate (camara), the price is not observable and, therefore, models must be used to estimate the future cash flows of the contract. This spread is calculated on a historical basis using the IRS with the greatest market depth, which is the chamber swap.

In addition, the Bank offers American forwards to meet its customers' needs. They do not have a secondary market and, therefore, their value is estimated using an extension of the Hull-White model, used widely by the financial services industry.

None of these products generate significant impacts on the Bank's results as a result of recalibration. The TAB swap does not have significant impacts on the valuation as the parameters are stable and the reversal to a historic average is empirically quick, which this model reflects correctly. On the other hand, the American forward behaves like a traditional forward when there is an important curve differential, which is the case between the Chilean peso-US dollar curve. Also, the model's parameters are very stable.

The table below summarizes the impacts on the portfolio of a recalibration of the models based on a stress scenario, recalibrating parameters with the shock incorporated.

d)	Transfers between level 1 and level 2

For the three-month period ended on March 31, 2021 and for the year ended on December 31, 2020, no transfers were performed between level 1 and 2.

e)	Disclosures Regarding Level 3 Assets and Liabilities

Level 3 assets and liabilities are valued using techniques that require inputs that are not observable on the market, for which the income approach is used to convert future amounts to present amounts.

This category includes:

●	Financial derivative instruments indexed to the TAB rate. This rate is comprised of an interbank rate and a liquidity premium charged to financial institutions and is determined using a short-rate model with mean reversion.

●	American forward options.

As none of these products has a market, the Bank uses financial engineering valuation techniques that use unobservable variables.

These techniques use the following inputs: transaction prices from the main financial instrument markets and assumptions that are widely accepted by the financial services industry. Using this information, unobservable variables are constructed such as: adjustment curves, spreads, volatilities and other variables necessary for the valuation. Lastly, all of the models are subject to internal contrasts by independent areas and have been reviewed by internal auditors and regulators.

None of these products generate significant impacts on the Bank's results as a result of recalibration. The American forward is only offered for the US dollar-Chilean peso market and until now, given the important differential between these interest rates, the product behaves like a traditional forward. The TAB swap does not have significant impacts on the valuation as the modeled liquidity premiums have a quick mean reversion for the short part and low volatility for the long part, concentrating on the book's sensitivity in the longest part of the curve.

Note 35 - Risk Management

The following is information related to the Bank's Risk Management, regarding the main risks that affect the Bank and its subsidiaries:

a) Credit Risk

Credit risk is the risk of potential loss that it faces, if a client or counterparty in a financial instrument does not comply with its contractual obligations to the Bank.

For Itaú Corpbanca, adequate risk management in all areas and, in particular, with regard to credit risk is one of the fundamental pillars for managing the Bank's portfolio, ensuring that it maintains an adequate risk / return ratio. It should be noted that this management includes both the credit risk originated by the effective placements, as well as by the contingent placements.

The Credit Managements have autonomy vis-à-vis the business areas and their size and organization are in accordance with the demands demanded by the size of the portfolio, as well as the complexity of the operations.

For the management, administration and monitoring of credit risk, each Credit Risk Management uses tools and methodologies that are in accordance with the segments they address. These allow an appropriate control of the risk, according to the size and complexity of the operations carried out by the Bank.

The Bank has a structure of Credit Committees associated with the Debtor's Risk Rating and with attributions based mostly on the committees in which Risk Managers participate. On certain amounts, a concurrence of Bank Directors is required.

It is these committees that define the levels of individual and group exposure to clients, as well as the mitigating conditions such as guarantees, credit agreements or others. As part of the policies it is defined that all customers must be analyzed at least once a year, when the line is renewed (situation that occurs first), or by activation of any alert.

a.1) Individual portfolio risk assessment

The Bank's risk management tool divides its portfolio into the following categories:

●	Normal risk portfolio

●	Substandard portfolio

●	Non-compliant portfolio

Normal risk portfolio

This includes debtors with payment capacity to comply normally with their obligations and commitments whose economic and financial situation shows no signs that this may change.

They are evaluated using a general parametric model with three qualitative factors (industry, shareholders and access to credit) and three quantitative financial position parameters, which are weighted based on the Bank's total sales.

Note 35 - Risk Management, continued

Substandard portfolio

It includes debtors with financial difficulties that significantly affect their payment capacity and about which there are reasonable doubts regarding repayment of all principal and interest in the contractually agreed-upon terms, showing little room to meet its financial obligations in the short term. Among other customers, this portfolio includes debtors with recent balances between 30 and 90 days overdue that can be attributed to the company's performance.

They are evaluated using a default parametric model that includes payment behavior and also considers the impact of negative results (losses).

Non-compliant portfolio

This portfolio is comprised of debtors managed by the Normalization Area and that come from clients with individual classification in default and all the clients that present some expired transaction originated by problems in their capacity to pay, regardless of their rating.

Monthly, the Asset Control and Classification Area checks that this provision is complied with.

a.2) Collectively risk assessed portfolios

To determine the provisions, group evaluations require the formation of groups of credits with homogeneous characteristics in terms of type of debtors and agreed conditions, in order to establish, by means of technically based estimates and following prudential criteria, both the payment behavior of the group in question as the recoveries of their unfulfilled credits.

The non-performing portfolio includes all placements and 100% of the amount of the contingent loans of debtors who, at the end of a month, have any of the following conditions:

i) Overdue equal to or greater than 90 days in the payment of interest or principal of any loans;

ii) they are granted a loan to leave an operation that had more than 60 days of delay in its payment and

iii) it has been subject to forced restructuring or partial debt cancellation.

All other credits that do not follow the restrictions indicated previously for the group portfolio, are identified as part of the normal portfolio.

a.3) Financial instruments

The Bank, for this type of asset, measures the probability of uncollectibility to issuers using internal ratings and, when they are available, external such as independent risk evaluators of the Bank.

b) Financial Risk

Definition and principles of financial risk management

The Bank defines this risk as the possibility of an event having unexpected financial consequences on the institution. Although this definition involves a strong adversity component, it also involves an important opportunity component. Therefore, the purpose of financial risk management is not to eliminate this risk, but rather to limit its exposure to negative events in line with the risk appetite of the Bank's shareholders and the regulations that govern the institution. The main financial risks to which the Bank is exposed are: Market Risk, Liquidity Risk and Counterparty Risk.

b.1) Market Risk

Market Risk is the exposure to economic gains or losses caused by movements in prices and market variables. This risk stems from the activities of the Trading and Banking Books. In the first case, it comes from activities intended to obtain short-term gains and from the intensive use of fair value instruments. In the second case, with a more long-term vision, it stems from commercial activities with products valued at amortized cost.

The following section describes the main market risk factors to which the Bank and its subsidiaries are exposed:

b.1.1) Currency Risk

Currency risk is the exposure to adverse movements in the exchange rates of currencies other than their base currency (CLP in the case of operations in Chile and COP in the case of operations in Colombia) for all those positions inside and outside of balance. The main sources of exchange risk are:

• Positions in foreign currency (MX) within the attributions of the Trading Book.

• Currency mismatches between the assets and liabilities of the Banking Book.

• Currency flow mismatches.

• Structural positions, generated by consolidating our financial statements, assets and liabilities denominated in currencies other than the Chilean peso registered in our branches and subsidiaries abroad.

The foregoing means that movements in exchange rates can generate volatility in both the result and the Bank's equity. This effect is known as 'translation risk'.

b.1.2) Inflation-indexation and exchange-indexation

The inflation-indexation and exchange-indexation risk is the exposure due to changes in units or indexes of adjustment (such as UF, UVR or others) defined in national or foreign currency, in which some of the instruments, contracts or other transactions registered in the balance with such characteristics.

b.1.3)Interest Rate Risk

Interest Rate Risk is the exposure to movements in market interest rates. Changes in market interest rates can affect both the price of instruments recorded at fair value and the financial margin and other gains from the Banking Book such as fees. Fluctuations in interest rates also affect the Bank's economic value. Interest rate risk can be represented by sensitivities to parallel and/or non-parallel yield shifts with the effects reflected in the prices of instruments, the financial margin, equity and economic value.

The measurement of the structural interest rate risk is carried out through the representation by risk factor of the cash flows expressed in fair value, assigned on the dates of repricing and by currency. This methodology facilitates the detection of concentrations of interest risk in the different terms. All the balance sheet and off-balance sheet items are unbundled in their flows and placed at the repricing/maturity. In the case of those accounts that do not have a contractual maturity, an internal model of analysis and estimation of their durations and sensitivities is used.

Note 35 - Risk Management, continued

b.1.4) Volatility risk

In addition to the exposure associated with the underlying asset, the issuance of options involves other risks. These are caused by the non-linear relationship between the profit generated by the option and the price and the levels of the underlying factors, as well as by exposure to changes in the volatility of the price of the underlying asset.

b.2)Liquidity Risk

Liquidity Risk is the exposure of the Bank's and its subsidiaries to events that affect their ability to meet, in a timely manner and at reasonable costs, cash payment obligations arising from maturities of time deposits that are not renewed, withdrawals from demand accounts, maturities or settlements of derivatives, liquidations of investments or any other payment obligation.

Financial institutions are exposed to funding liquidity risk that is intrinsic to the role of intermediary that they play in the economy. In general, in financial markets demand for medium or long-term financing is usually much greater than the supply of funds for those terms while short-term financing is in considerable supply. In this sense, the role of intermediary played by financial institutions, which assume the risk of satisfying the demand for medium and long-term financing by brokering short-term available funds, is essential for the economy to function properly.

Normative Measurement of Contractual Liquidity GAP

According to chapter 12-20 of the RAN, all the items on and off the balance sheet that contribute cash flows are analyzed. The consolidated non-discounted contractual cash flows of financial assets and liabilities of the Bank as of March 31, 2021 and December 31, 2020, are presented below:

B.3) LIBOR discontinuation (London Interbank Offered Rate)

The LIBOR has been the main reference to determine the price of financial instruments from mortgages, loans, bond, derivatives, as well as for the construction of discount rates and transfer prices. However, it has recently been challenged its reliability and methodological definition, prompting the UK's Financial Conduct Authority (FCA) to dictate in 2017 and propose the cesation of the LIBOR benchmart December 31, 2021 as the deadline for LIBOR.

By virtue of the foregoing, as of December 31, 2020, the bank has completed the diagnostic phase to determine the impact of transitioning to an alternative rate and is in the process of drawing up a plan for its implementation.

The following table details the exposure based on financial instruments subject to the reform of the reference interest rate, presenting the balances as of March 31, 2021:

Note 35 - Risk Management, continued

The main items identified included in Loans and accounts receivable from customers correspond to commercial loans in the form of working capital funding, while the operations included in the Interbank borrowings item correspond mainly to international trade financing operations. The derivative items are mainly composed of interest rate swaps.

Additionally, based on Management's analysis, no risks have been identified that would required meaningful modifications in the risk management strategy implemented by the Bank.

C) Operational Risk

The Bank and its subsidiaries define operational risk as the possibility of occurrence of losses resulting from failures, deficiencies or inadequacies in internal processes, people, and systems or external events, including in this definition the legal risk and excluding strategic risks and reputational. Operational risk is recognized as a manageable risk, for which it has defined a function in charge of this task within its corporate structure.

Operational risk management is executed, mainly, through the Operational Risk Management function. The Bank adopts a model of three lines of defense as the primary way to implement its operational risk management structure, internal controls and compliance, ensuring compliance with corporate guidelines.

The defense lines are composed by; the business and support areas (first line of defense) responsible for managing the risks related to their processes; Operational Risk, Internal Controls, and Compliance (second line of defense) area in charge of supporting the first line of defense in relation to the fulfillment of its direct responsibilities; and Internal Audit function (third line of defense) responsible for verifying, independently and periodically, the adequacy of the risk identification and management processes and procedures, in accordance with the guidelines established in the Internal Audit Policy and submitting the results of its recommendations for improvement to the Audit Committee.

The risk management program contemplates that all relevant risk issues must be reported to the higher levels and to the Operational Risk Committee.

Note 35 - Risk Management, continued

Our methodology consists in the evaluation of the risks and controls of a business from a broad perspective and includes a plan to monitor the effectiveness of such controls and the identification of eventual weaknesses. The main objectives of the Bank and its subsidiaries in terms of operational risk management are the following:

• Identification, evaluation, information, management, and monitoring of the operational risk in connection with activities, products, and processes carried out or commercialized by the Bank and its subsidiaries;

• Build a strong culture of operational risk management and internal controls, with clearly defined and adequately segregated responsibilities between business and support functions, whether these are internally developed or outsourced to third parties;

• Generate effective internal reports in connection with issues related to operational risk management, with a clearly defined escalation protocol;

• Control the design and application of effective plans to deal with contingencies that ensure business continuity and losses control.

Regarding training and awareness, the risk culture continues to be reinforced through face-to-face training in the field of operational risk, internal control, prevention of external and internal fraud, and the implementation of the annual 'more security' program for all collaborators and induction programs for new employees.

​

Finally, it is worth mentioning that Sarbanes-Oxley methodologies (SOX) continue to be applied for their main products and processes, the application of this methodology is annually certified by an external consultant.

D) Cybersecurity

The Bank and its affiliated companies collect and process personal and confidential information from its clients as an integral part in the conduct of banking operations and the various services offered through the Internet and other electronic channels. The secure transmission of information through the different electronic channels is essential to maintain the trust of its customers in online services. The use of the Internet and electronic channels exposes the Bank to risks associated with cybersecurity.

Cybersecurity is defined as the set of actions for the protection of digital information assets, as well as the infrastructure that supports it, with the objective of preventing or mitigating the adverse effects of risks and threats on information security and maintaining the continuity of the Bank's business.

Given the importance of cybersecurity and security of the clients' information, the Bank has a Cybersecurity and Fraud Management team, which reports directly to the Corporate Risk Manager.

The Bank's Cybersecurity Management model is based on four (4) Macro processes:

1)	Security and Cybersecurity Governance: focused on risk management, regulatory framework, supplier cybersecurity management and culture and awareness of Cybersecurity culture, for clients and collaborators.

2)	Information protection: Responsible for the identification, classification, protection and authorization of access to information.

3)	Systems security: Definition of security architecture and adherence to cybersecurity guidelines in the technological environment.

4)

Cyber defense: Application of industry leading practices in security and assurance of technological equipment (Baseline), detection and remediation of vulnerabilities and detection and response to cybersecurity incidents; evaluation of the Bank's current cybersecurity controls and detection of cybersecurity breaches, evaluation of response to a crisis scenario through cybersecurity exercises and ethical hacking.

E)	Capital requirements

The primary objectives of capital management are to ensure compliance with regulatory requirements and to maintain a solid risk rating and healthy capital ratios. During the periods ended on March 31, 2021 and December 31, 2020, the Bank has fully complied with all capital requirements.

In accordance with the General Banking Law, the Bank must maintain a minimum ratio of Regulatory Capital to Consolidated Risk-Weighted Assets of 8%, net of required provisions, and a minimum ratio of Core Capital to Total Consolidated Assets of 3%, net of required provisions. However, after the merger, the CMF determined that the Bank's Regulatory Capital could not be less than 10% of its Risk-Weighted Assets. For this purpose, the Bank has applied the dispose in the Chapter 12-1 'Equity for legal and regulatory purposes' of RAN.

Assets are weighted using risk categories, which are assigned a risk percentage based on the capital needed to back up each asset. There are 5 risk categories (0%, 10%, 20%, 60% and 100%) and additionally a category intermediate with a risk weighting percentage of 2%. For example, cash, due from banks and financial instruments issued by the Chilean Central Bank have 0% risk, which means that, in accordance with current standards, no capital is required to back these assets. Property, plant and equipment have 100% risk, which means that a minimum capital equivalent to 8% of the value of these assets is needed. In the case of Itaú, it uses 10%.

All derivative instruments traded off-market are taken into account to determine risk assets using conversion factors over notional values, thus calculating the value of the credit risk exposure (or 'credit equivalent'). For weighting purposes, 'credit equivalent' also considers contingent loans not recorded in the Consolidated Statement of Financial Position.
