(b) Global pandemic Covid-19 (b.1) State of National and Sanitary Emergency In December 2019, a new coronavirus strain (SARS-CoV-2) “Covid-19”, Covid-19 In the case of Peru, in March 2020, the Government declared a State of National and Sanitary Emergency ordering the closure of borders, mandatory social isolation, the closure of businesses considered non-essential Subsequently, in May 2020, through Supreme Decree No. 080-2020, Notwithstanding the aforementioned, due to the increase in the number of infections at national level, through Supreme Decree No. 009-2021, 036-2021-PCM, (b.2) Economic measures adopted by the Peruvian Government Within this context, the Ministry of Economy and Finance (henceforth “MEF”), the Central Reserve Bank of Peru (henceforth “BCRP”) and the Superintendence of Banking and Insurance and private Pension Fund Administrators (henceforth “SBS”), activated extraordinary measures aimed to alleviate the financial and economic impact of Covid-19, The main measures implemented in the financial system are related to facilities for loan rescheduling (payment deferrals), suspension of counting of past due days, partial withdrawal of deposits from compensation from service time accounts, setting of Repo operations with the BCRP and the launching of credit programs guaranteed by the Peruvian Government, such as “Reactiva Peru”, created through Legislative Decree No. 1455-2020 and expanded through Supreme Decree No. 1486-2020, which has the purpose to secure the continuity of companies’ payment chain to face the impact of Covid-19. Such program grants guarantees to companies to obtain working capital loans and thus fulfill their short-term obligations to their workers and suppliers of goods and services. This program manages guarantees for the entire Peruvian financial system whose total amounted to S/60,000 million. As of December 31, 2020, Interbank holds loans of the “Reactiva Peru” program for an amount of S/6,615,768,000, from which S/5,855,826,000 are guaranteed by the Peruvian Government. (b.3) Measures adopted by the Company and Subsidiaries Management and the Board of IFS monitors the situation closely and is focusing on four fundamental pillars which is going to allow the continuity of its operations; taking the following measures in each one of these pillars: i) Liquidity and solvency Active participation in the BCRP’s daily operations, thus raising funds through loan reporting operations represented by securities. These funds were aimed to loans under the “Reactiva Peru” program, which in turn allowed a higher collection in the levels of deposits. Likewise, in order to strengthen its capital and regulatory capital to face with the volatile environment, the Group implemented the following measures: • The General Shareholders’ Meeting of Interbank held on April 3, 2020, approved the reduction in the percentage of distributable dividends for the 2019 period, from 45 percent to 25 percent.

Significant accounting policies	3. Significant accounting policies 3.1 Basis of presentation - The consolidated financial statements have been prepared in accordance with the International Financial Reporting Standards (henceforth “IFRS”) as issued by the International Accounting Standards Board (henceforth “IASB”) and are presented in Soles, which is the functional currency of the Group. All values are rounded to the nearest thousand (S/(000)), except when otherwise indicated. The preparation of the consolidated financial statements in conformity with the IFRS requires Management to make estimations and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosure of significant events in the notes to the consolidated financial statements; see Note 3.6. 3.2 Adoption of new standards and disclosures - In these consolidated financial statements, the Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective. The following standards, interpretations or amendments have been adopted for the first time in 2020, but they have not had a significant impact on the Group’s consolidated financial statements • Amendments to IFRS 3 “Business Combinations” The amendment to IFRS 3 clarifies that to be considered a business, an integrated set of activities and assets must include, at a minimum, an input and a substantive process that, together, significantly contribute to the ability to create output. Furthermore, it clarifies that a business can exist without including all of the inputs and processes needed to create outputs. These amendments did not have any impact on the Group´s consolidated financial statements, but may impact future periods if the Group enters into any business combinations. • Amendments to IAS 1 “Presentation of Financial Statements” and IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors” The amendments provide a new definition of “material” that states, “information is material if omitting, misstating or obscuring it could reasonably be expected to influence decisions that the primary users of general financial statements make on the basis of those financial statements, which provide financial information about a specific reporting entity”. The amendments clarify that materiality will depend on the nature or magnitude of information, either individually or in combination with other information, reported in the context of the financial statements. A misstatement of information is material if it could reasonably be expected to influence decisions made by the primary users. These amendments did not have any significant impact on the Group´s consolidated financial statements. • Conceptual Framework for Financial Reporting issued on March 29, 2018 Although the Conceptual Framework is not a standard, its purpose is to assist the IASB in developing standards, to help preparers develop consistent accounting policies where there is no applicable standard in place and to assist all parties to understand and interpret the standards. The revised Conceptual Framework includes some new concepts, updated definitions and recognition criteria for assets and liabilities and clarifies some important concepts. These amendments did not have any impact on the Group´s consolidated financial statements. • Amendments to IFRS 16 “Leases” In May 2020, the IASB issued amendment to IFRS 16 that provide relief to lessees from the application of said standard, which are related to lease modification accounting for rent concessions for Covid-19 Covid-19 Covid-19 This amendment did not have an impact on the Group´s consolidated financial statements. Since January 1, 2019, the Group is applying: (i) IFRS 16 “Leases”, whose accounting policies and impacts are described in Notes 3.4(j) and 8(e); and (ii) the first phase of the amendments to IFRS 9 “Financial Instruments”, IAS 39 “Financial Instruments: Recognition and Measurement”, and IFRS 7 “Financial Instruments: Disclosures”; referred to the Interest rate benchmark reform, whose accounting policies and impacts are described in Notes 3.4(ag) and 10(b)(vi). 3.3 Basis of consolidation - The consolidated financial statements comprise the financial statement of IFS and its Subsidiaries (see Note 2). For accounting consolidation purposes, control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns. Specifically, the Group controls an investee if and only if the Group has: • Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee); • Exposure, or rights, to variable returns from its involvement with the investee; and • The ability to use its power over the investee to affect its returns. Generally, it is presumed that a majority of voting rights entitles to control. In order to support this presumption and when the Group has less than the majority of votes or similar rights in the investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including: • The contractual arrangement with the other vote holders of the investee; • Rights arising from other contractual arrangements; and • The Group’s voting rights and potential voting rights. The Group assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation with a Subsidiary begins when the Group obtains control over the Subsidiary and ceases when the Group loses control of the Subsidiary. For consolidation purposes, profit and loss and each component of other comprehensive income (“OCI”) are attributed to the equity holders of the Group’s parent Company and to the non-controlling non-controlling The subsequent acquisition of the non-controlling non-controlling non-controlling Assets in custody or managed by the Group, such as investment funds and others, are not part of the Group’s consolidated financial statements; see Note 3.4(ab). 3.4 Summary of significant accounting policies (a) Foreign currency translation - Functional and presentation currency: The Group has determined that its functional and presentation currency is the Sol, because it reflects the economic substance of the underlying events and circumstances relevant to most of the Group’s entities, insofar as its main operations and/or transactions, such as loans granted, financing obtained, sale of insurance premiums, interest and similar income, interest and similar expenses and an important percentage of purchases are established and settled in Soles; in addition, it corresponds to the functional currency to most of the Subsidiaries; except for Inteligo Bank, whose functional currency is the US Dollar. Because Inteligo Bank has a functional currency different from the Sol, its balances were translated for consolidation purposes using the methodology established by IAS 21 “The Effects of Changes in Foreign Exchange Rates”, as follows: • Assets and liabilities at the closing rate at the date of each consolidated statement of financial position. • Income and expenses, at the average exchange rate for each month. As a result of the translation, the Group has recorded the difference in the caption “Exchange differences on translation of foreign operations” in the consolidated statement of other comprehensive income. Foreign currency balances and transactions: Foreign currency transactions and balances are those performed in currencies different from the functional currency. Transactions in foreign currencies are initially recorded in the functional currency using the exchange rate at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the exchange rate in effect on the reporting date. The differences between the closing rate at the date of each consolidated statement of financial position presented and the exchange rate initially used to record the transactions in foreign currency are recognized in the consolidated statement of income in the period in which they arise, in the caption “Translation result”. Non-monetary (b) Interest income - (b.1) Effective interest rate method - Interest income is recorded using the effective interest rate (“EIR”) method for all financial assets measured at amortized cost, interest rate derivatives for which hedge accounting is applied and the related amortization/recycling effect of hedge accounting. The interest income of financial assets that accrue interests measured at fair value through other comprehensive income according to IFRS 9 is also recorded using the EIR method. Interest expenses are also calculated using the EIR method for all financial liabilities held at amortized cost. EIR is the rate that exactly discounts estimated future cash flows through the expected life of the financial instrument or, when appropriate, a shorter period at the net carrying amount of the financial asset. The EIR is calculated by taking into account transaction costs and any discount or premium on the acquisition of the financial asset, as well as fees and costs that are an integral part of the EIR. The Group recognizes interest income using the best estimate of a constant rate of return over the expected life of the financial asset. Therefore, the EIR calculation also takes into account the effect of potentially different interest rates that may be charged at various stages of the financial asset’s expected life, and other characteristics of the product’s life cycle (including prepayments, penalty interest and charges). If expectations of fixed rate financial assets’ or liabilities’ cash flows are revised for reasons other than credit risk, then changes to future contractual cash flows are discounted at the original EIR, and the adjustment is recorded as a positive or negative adjustment of the carrying amount of the financial asset in the consolidated statement of financial position with an increase or decrease in Interest revenue. For floating-rate financial instruments, periodic re-estimation re-estimating (b.2) Interest income and similar - The Group calculates the interest income by applying the EIR to the gross carrying amount of non-impaired When a financial asset becomes impaired, and, therefore, it is classified as Stage 3 (as established in Note 3.4(h), the Group calculates the interest income by applying the EIR at the amortized cost of the asset. If the financial assets “recover”, as detailed in Note 30.1(d), and is no longer impaired, the Group recalculates the interest income in gross figures. For purchased or originated credit-impaired (POCI) assets, as established in Note 30.1(d), the Group calculates the interest income by determining the credit-adjusted EIR at the amortized cost of the asset. The credit-adjusted EIR is the interest rate that, in the initial recognition, discounts the estimated future cash flows (including credit losses) at the amortized cost of POCI assets. The interest income for all trading assets, that is, for those that are measured at fair value through profit or loss, are presented under the caption “Net gain (loss) of financial assets at fair value through profit or loss” of the consolidated statement of income. (c) Banking services commissions - The Group earns fee and commission income from a diverse range of financial services it provides to its customers. Fee and commission income is recognized at an amount that reflects the consideration to which the Group expects to be entitled in exchange for providing the services. The performance obligations, as well as the timing of their satisfaction, are identified and determined at the inception of the contract. The Group’s income from contracts do not typically include multiple performance obligations. When the Group provides a service to its clients, the consideration is invoiced and generally due immediately upon satisfaction of a service provided at a point in time or at the end of the contract period for a service provided over time. The Group has generally concluded that it is the principal in its revenue arrangements because it typically controls the services before transferring them to the customer. The fees included in the caption “Fees for banking services, net” that make up part of the consolidated statement of income include fee income where performance obligations are satisfied at a specific time or over a period of time. Fee income where performance obligations are satisfied over a period of time include, among others, collection services, funds management, memberships, fees for contingent loans and credit card insurance. Likewise, fee income where performance obligations are satisfied at a specific time include, among others, banking service fees, brokerage and custody services, and credit card fees. Below is the main income from contracts with customers that are recognized in the consolidated statement of financial position: • Fees receivable for credit cards and certain fees receivable for letters of guarantee included in the caption “Other accounts receivable and other assets, net”, represent the Group’s right to an unconditional consideration (i.e., it only requires the passing of time for the consideration payment). This income is measured at amortized cost and is subject to impairment specifications under IFRS 9. • Deferred income from commissions for letters of guarantee included in the caption “Other accounts payable, provisions and other liabilities”, represent the Group’s obligation to render services to a customer, from whom the Group has received a consideration (or a due amount). A liability for unearned fees and commissions is recognized when the payment is made or when the payment is due (whichever happens first). Unearned fees and commissions are recognized as income when the Group renders the service. (d) Insurance contracts – Accounting policies for insurance activities: The Group applies to insurance contracts the existing accounting policies prior to the adoption of IFRS (i.e., accounting standards established by the SBS for financial and insurance entities in Peru) with certain modifications as described below: • Incurred but not reported claims reserves (IBNR): These reserves are calculated and applied at each recording period using the Chain Ladder methodology, which considers past experience based on cumulative claims losses to estimate future claims developments. • Technical reserves for life annuities and retirement, disability and survival pensions: Until May 31, 2018, to calculate the reserve of insurance contracts; the Group considered the Chilean current mortality and morbidity tables (improved RV–2009, B–2006 and MI–2006). In addition, to discount the future cash flows of these liabilities, for portfolio’s debt instruments, the Group set an average rate for matching periods and a 3-percent non-matching SPP-S-2017 SPP-I-2017 No. 886-2018 As previously mentioned, in 2018, the Group’s Management decided to modify its accounting policy and reflect the effect of the change in the value of liabilities coming from retirement, disability and survival pensions, caused by the variations in the market interest rate used to discount these liabilities, in the consolidated statement of other comprehensive income (formerly reflected in the consolidated statement of income). This change was made to reduce the volatility in the profits or losses associated to the effect of changes in market interest rates, as the financial assets supported such insurance liabilities were measured at fair value through other comprehensive income. Likewise, it modified the assumptions used in the determination of the discount rate with the purpose of reflecting the business nature in the long term. The effect of the first application of SPP-S-2017 SPP-I-2017 The effects of the first application of “Matching Adjustement” interest rates as of June 1, 2018, amounted to S/423,080,000; which, according to IAS 8, was prospectively recognized and was part of the year’s movement in other comprehensive results within the caption “Unrealized results, net”, in the year 2018. Product classification: Insurance contracts are those contracts where the Group (the insurer) has accepted significant insurance risk from another party (the policyholder) by agreeing to compensate the policyholder for a specified uncertain future event (the insured event) that adversely affects the policyholder. As a general guideline, the Group determines whether it has significant insurance risk by comparing benefits paid with benefits payable if the insured event did not occur. Insurance contracts may also transfer a financial risk. When the contract has a financial component and transfers no relevant insurance risk as established by IFRS 4 “Insurance Contracts”, the contract is recorded based on IFRS 9 “Financial Instruments”. These contracts are presented in the caption “Other accounts payable, provisions and other liabilities” as “Contract liability with investment component” of the consolidated statement of financial position; see Note 10(a). Once a contract has been classified as an insurance contract, it remains as an insurance contract for the remainder of its life, even if the insurance risk is reduced significantly during this period, unless all rights and obligations are extinguished or expire. Life insurance contracts offered by the Group include retirement, disability and survival insurance, annuities and group and individual life. Non-life Insurance receivables: Insurance receivables are initially recognized when due and are measured at the fair value of the consideration received or receivable. Consequently, in its initial recognition, insurance receivables are measured at amortized cost. As of December 31, 2020 and 2019, the carrying value of the insurance receivables is similar to their fair value due to their short-term maturity. The carrying value of insurance receivables is reviewed for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable, with the impairment loss recorded in the consolidated statement of income. Reinsurance: The Group cedes the insurance risk in the normal course of its operations mainly due to pension fund risks and life insurance risks (individual and group). The reinsurance assets represent balances due and payable by reinsurance companies. Reinsurance is ceded on a proportional basis. The amounts recoverable from the contracts with reinsurers are estimated consistently with the loss reserve pending settlement or losses settled and with the premiums ceded, associated with policies ceded, in accordance with the clauses established in the related reinsurance contracts. Reinsurance assets are reviewed for impairment at each date of the consolidated statement of financial position or more frequently when necessary. Impairment arises when there is objective evidence the Group cannot receive all of the outstanding amounts receivable under the contract terms and the event has a reliably measurable impact on the amounts that the Group will obtain from the reinsurer. Impairment loss is registered in the consolidated statement of income. Reinsurance contracts ceded do not release the Group from its obligations to the insured. The liabilities from reinsurance contracts represent balances due and payable to reinsurance companies. The amounts payable are estimated consistently with the related reinsurance contract. Premiums and claims are presented as gross amounts for the reinsurance ceded. Reinsurance assets or liabilities are written off when the contractual rights are extinguished, expire, or when the contract is transferred to a third party. Reinsurance commissions: The commissions from the reinsurance contracts for premiums ceded are amortized on a straight-line basis over the term of the related insurance contract. Insurance contract liabilities: Life insurance contract liabilities are recognized when contracts are entered into. The technical reserves for retirement, disability and survival insurance and annuities are determined as the sum of the discounted value of expected future pensions to be paid during a defined or non-defined Individual life technical reserves are determined as the sum of the discounted value of expected future benefits, administration expenses, policyholder options and guarantees and investment income, less the discounted value of the expected premiums that would be required to meet the future cash outflows. Furthermore, the technical reserves for group life insurance contracts comprise the provision for unearned premiums and unexpired risks. Insurance claims reserves include reserves for reported claims and an estimate of the IBNR. As of December 31, 2020 and 2019, IBNR reserves were determined on the basis of the Chain Ladder methodology, whereby the weighted average of past claims’ development is projected into the future. Adjustments to the liabilities at each reporting date are recorded in the consolidated statement of income. The liability is derecognized when the contract expires, is discharged or cancelled. At each reporting date an assessment is made on whether the recognized life insurance liabilities are sufficient, by using an existing liability adequacy test as established by IFRS 4. In the case of annuities and retirement, disability and survival insurance, this test was conducted by using current assumptions for mortality and morbidity tables and interest rates. As of December 31, 2020 and 2019, Management determined that liabilities were sufficient and therefore, it has not recorded any additional life insurance contract liability. The accounts payable to reinsurers and coinsurers arise from the ceded premiums issued based on the evaluation of the risk assumed and the losses coming from the reinsurance contracts accepted as well as from the clauses executed for the coinsurance received, and are registered in the item “Accounts payable to reinsurers and coinsurers” that is part of the caption “Other accounts payable, provisions and other liabilities” of the consolidated statement of financial position. Income recognition: Life insurance contracts: Gross premiums on life insurance are recognized as revenue when due from the policyholder. For single premium products, revenue is recognized on the date when the policy is effective. The net premiums earned include the annual variation of technical reserves. Property, casualty and group life insurance contracts: Unearned premiums are those proportions of premiums written in a year that relate to periods of risk afterwards the reporting date. Unearned premiums are calculated on a daily pro rata basis. The proportion attributable to subsequent periods is deferred as a provision for unearned premiums. Recognition of benefits, claims and expenses: (i) Gross benefits and claims Gross benefits and claims for life insurance contracts include the cost of all claims arising during the year, including internal and external claims handling costs that are directly related to the processing and settlement of claims. Death, survival and disability claims are recorded on the basis of notifications received. Annuities payments are recorded when due. (ii) Reinsurance premiums Reinsurance premiums comprise the total premiums payable for the whole coverage provided by contracts entered into in the period and are recognized at the date at which the policy is effective. Unearned ceded premiums are deferred during the period of the related insurance contract. (iii) Reinsurance claims Reinsurance claims are recognized when the related gross insurance claim is recognized according to the terms of the relevant contract. (iv) Acquisition costs Acquisition costs related to the sale of new policies are recognized when incurred. (e) Financial instruments: Initial recognition - (e.1) Date of recognition Financial assets and liabilities, with the exception of loans, are initially recognized at the trading date. This includes regular transactions of purchases or sales of financial assets that require the delivery of assets within the time frame generally established by regulation or convention on the marketplace. Loans are recognized when the funds are transferred to the customers while deposits and obligations are recognized when the funds are received by the Group . (e.2) Initial measurement of financial instruments The classification of financial instruments at initial recognition depends on the characteristics of the business model and contractual flows for managing the instruments, as described in Notes 3.4(f.1.1) and 3.4(f.1.2). Financial instruments are initially measured at their fair value (as defined in Note 3.4(e.4)), except in the case of financial assets and financial liabilities recorded at fair value through profit or loss, transaction costs are added to, or substracted from, this amount. Accounts receivable are measured at the transaction price. When the fair value of financial instruments at initial recognition differs from the transaction price, the Group accounts for the Day 1 profit or loss, as described below. (e.3) Day 1 profit or loss When the transaction price of the instrument differs from the fair value at origination and the fair value is based on a valuation technique that only uses inputs observable in market transactions, the Group recognizes the difference between the transaction price and fair value in the net trading income. In those cases where fair value is based on models for which some of the inputs are not observable, the difference between the transaction price and the fair value is deferred and is only recognized in profit or loss when the inputs become observable, or when the instrument is derecognized. It should be noted that during the years 2020 and 2019, the Group did not originate any differences related to these characteristics. (e.4) Measurement categories of financial assets and liabilities The Group classifies all of its financial assets based on the business model and the contractual terms, measured at either: • Amortized cost, as explained in Note 3.4(f.1). • Fair value through other comprehensive income, as explained in Notes 3.4(f.4) and (f.5). • Fair value through profit or loss, as explained in Note 3.4(f.7). The Group classifies and measures its derivative and trading portfolio at fair value through profit or loss as explained in Notes 3.4(f.2) and (f.3). The Group may designate financial instruments at fair value through profit or loss, if so doing eliminates or significantly reduces measurement or recognition inconsistencies, as explained in Note 3.4(f.7). Financial liabilities, other than financial guarantees, are measured at amortized cost or at fair value through profit or loss when they are held for trading, are derivative instruments or the fair value designation is applied, as explained in Note 3.4(f.6). It should be noted that during 2020 and 2019, the Group only presents derivative financial instruments measured in this way. (f) Financial assets and liabilities - Following is the description of the assets and liabilities held by the Group, as well as the criteria for their classification: (f.1) Assets measured at amortized cost - As required by IFRS 9, the Group measure cash and due from banks inter-bank funds, financial investments in debt instruments, loans and other financial assets at amortized cost if the following two conditions are met: • The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows, and • The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding. The details of these conditions are presented below: (f.1.1) Business model assessment - The Group’s business model is assessed at a higher level of aggregated portfolios, and not instrument by instrument, and is based on observable factors such as: • How the performance of the business model and the financial assets held within that business model are assessed and reported to the entity’s key management personnel. • The risks that affect the performance of the business model (and the financial assets held within that business model) and, in particular, the way those risks are managed. The expected frequency, value and timing of sales are also important aspects of the Group’s assessment. The business model assessment is based on reasonably expected scenarios without taking “worst case” or “stress case”. If cash flows after initial recognition are realized in a way that is different from the Group’s original expectations, the classification of the remaining financial assets that remain in that business model will not be changed, but incorporates such information when assessing newly purchased financial assets. (f.1.2) The SPPI test (Solely payments of principal and interest) - As a second step of its classification process, the Group assesses the contractual terms to identify whether they meet the SPPI test. “Principal”, for the purpose of this test, is defined as the fair value of the financial asset at initial recognition and may change over the life of the financial asset (for example, if there are repayments of principal or amortization of the premium/discount). The most significant elements within a lending arrangement are the time value of money and credit risk. To perform the SPPI assessment, the Group applies judgement and considers relevant factors such as the currency in which the financial asset is denominated, and the period for which the interest rate is set. In contrast, contractual terms that introduce volatility in the contractual cash flows that are unrelated to a basic lending arrangement do not give rise to contractual cash flows that are solely payments of principal and interest on the amount outstanding. In such cases, the financial asset is required to be measured at fair value through profit or loss. (f.2) Derivatives recorded at fair value through profit or loss - A derivative is a financial instrument or other contract with the following three characteristics: • Its value changes in response to the change in a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable; provided that, in the case of a non-financial • It requires no initial net investment or an initial net investment that is smaller than the required for other types of contracts expected to have a similar response to changes in market factors. • It is settled at a future date. The Group enters into derivative transactions with various counterparties, such as: interest rate swaps, cross-currency swaps, foreign currency options and foreign currency forward contracts. Derivatives are recorded at fair value and carried as assets when their fair value is positive and as liabilities when their fair value is negative. The notional amount and fair value of such derivatives are presented separately in Note 10(b). Changes in the fair value of derivatives are included in net trading income unless hedge accounting is applied. Hedge accounting disclosures are presented in Note 3.4(i). (f.2.1) Embedded derivatives - An embedded derivative is a component of a hybrid instrument that also includes a non-derivative non-financial independently of that instrument, or has a different counterparty from that instrument, is not an embedded derivative, but a separate financial instrument. Embedded derivatives in financial assets, liabilities and non-financial In the case of embedded derivatives in financial assets, they are not separated from the financial asset and, therefore, the classification rules are applied to the hybrid instrument in its entirety, as described in Note 3.4(e.4). As of December 31, 2020 and 2019, the Group does not present embedded derivatives needed to be separated from the host contract for being closely related. (f.3) Financial assets or financial liabilities held for trading - The Group classifies financial assets or financial liabilities as held for trading when they have been purchased or issued primarily for short-term profit making through trading activities or form part of a portfolio of financial instruments that are managed together, for which there is evidence of a recent pattern of short-term profit taking.

In the determination of the expected loss for the portfolio of financial investments, it has not been necessary to perform a subsequent adjustment to the model because it captures the expected loss in a satisfactory manner considering the Group portfolio investments. As a result of the assessment of the impairment of its debt instruments at fair value through other comprehensive income, the Group recorded an expense of S/32,904,000 and S/6,790,000 during 2020 and 2019, respectively, and a reversal of the impairment of S/13,077,000 during the year 2018, which are presented in the caption “(Loss) recovery to impairment of financial investments” in the consolidated statement of income. The movement of unrealized results of investments at fair value through other comprehensive income, net of Income Tax and non-controlling (d) As of December 31, 2020 and 2019, investments at amortized cost corresponds to Sovereign Bonds of the Republic of Peru issued in Soles, for an amount of S/2,707,298,000 and S/2,206,986,000, respectively, including accrued interest. Said investments present low credit risk and the expected credit loss is not significant. As of December 31, 2020, these investments have maturity dates that range from September 2023 to August 2037, have accrued interests at effective annual rates ranging from 4.29 percent and 5.15 percent, and estimated fair value amounting to approximately S/2,988,539,000 (as of December 31, 2019, their maturity dates ranged from September 2023 to August 2037, accrued interests at effective annual rates between 4.29 percent and 6.26 percent, and its estimated fair value amounted to approximately S/2,328,303,000). During the year 2019, the Government of the Republic of Peru performed public offerings to buyback certain sovereign bonds, with the purpose of renewing its debt and funding the fiscal deficit. Considering the purpose of this offering, subsequently to it, there should not be existing remaining sovereign bonds of the repurchased issuances or, in case of existing, they would become illiquid on the market. In that sense, Interbank took part of these public offerings and sold to the Government of the Republic of Peru sovereign bonds classified as investments at amortized cost for approximately S/340,518,000, generating a gain amounting to S/8,474,000, which was recorded in the caption “Net gain from derecognition of financial investments at amortized cost” of the consolidated statement of income. Notwithstanding the aforementioned, with the purpose of maintaining its asset management strategy, the Bank purchased simultaneously other sovereign bonds of the Republic of Peru for approximately S/340,432,000 and classified them as investments at amortized cost. In Management’s opinion and pursuant to IFRS 9, said transaction is congruent with the Group’s business model because although said sales were significant, they were infrequent and were performed with the sole purpose of facilitating the debt renewal and the funding of the fiscal deficit of the Republic of Peru, and thus the business model regarding these assets has always been the collection of the contractual cash flows. As of December 31, 2020 and 2019, Interbank keeps loans with the BCRP that are guaranteed with these sovereign bonds, classified as restricted, for approximately S/1,071,740,000 and S/762,347,000, respectively; see Note 12(b).

(f) Interest generated by loans are agreed upon freely considering prevailing market interest rates. It should be noted that as of December 31, 2020, the Congress of the Republic of Peru, approved a law that allows BCRP be the entity in charge to determine the maximum and minimum interest rates that can be charged in the Peruvian financial system. However, as of the date of this report, the BCRP has not yet applied the changes to the General Act of the Banking and Insurance System and Organic Act of the SBS, in order to incorporate the change approved by the Peruvian Congress, nor has established maximum and minimum interest rates. (g) Interest income from loans classified in Stage 3 is calculated through the effective interest rate adjusted for credit quality at amortized cost. (h) The refinanced loans during the 2020 period amounted to approximately S/188,311,000 (S/178,695,000, as of December 31, 2019) which had no significant impact on the consolidated statement of income.

1 to Stage 2 and Stage 3, and from Stage 2 to Stage 3 to capture the uncertainty and risks due to the pandemic situation. These migrations to higher risk Stages led to incurrence of higher provisions for expected losses during the year 2020 compared to the year 2019; see Note 30.1(d.4).

During 2019, main additions are outlays related to the construction of the “Chimbote” and “Chorrillos” educational centers. During 2018, main additions are outlays related to the construction of the buildings “Orquídeas” (San Isidro) and “Chorrillos” (both located in Lima). (e) During 2019, Interseguro sold to related entities, in cash and at market value, two land lots located in Miraflores and Huaral.

For these sales, Interseguro reported a net loss of about S/7,164,000. In January 2018, Interseguro sold, in cash and at market value, the Real Plaza Pucallpa shopping center, a parcel located in Lurín and a building through a surface rights agreement to related entities. Likewise, in October 2018, Interseguro sold, in cash and at market value, a parcel located in Arequipa to a related entity. For these sales, Interseguro recorded net profits amounting to S/4,655,000. (f) Fair value measurement – Investment property and investment property under construction Valuation techniques - The discounted cash flow (“DCF”) method is used for completed shopping malls, buildings and investment property built on land leases and own lands. This method involves the projection of a series of periodic cash flows at present value through a discount rate. The periodic calculation of the cash flows is normally determined as rental income net of operating expenses. The series of periodic net operating income, together with an estimation of the terminal value (which uses the traditional valuation method) at the end of the projection period, is discounted at present value. The sum of the net current values is equal to the investment property’s fair value. The fair value of land is determined based on the value assigned by an external appraiser. The external appraiser uses the market comparable method, under this method a property’s fair value is estimated based on comparable transactions. The unit of comparison applied by the Group is the price per square meter. Following are the minimum ranges, maximum ranges and the average price for the land, before any adjustment: Minimum range Maximum range Average US$ per m2 US$ per m2 US$ per m2 San Isidro – Lima 2,799 8,000 5,855 San Martin de Porres – Lima 1,332 1,611 1,540 Piura 1,000 1,200 1,100 Ate Vitarte - Lima 800 2,057 899 Others 230 313 257 Main assumptions Below is a brief description of the assumptions considered in the determination of cash flows as of December 31, 2020 and 2019: • ERV (Estimated Rental Value) - Corresponds to the Estimated Rental Value, that is, the rent for which the space could be rented under the market conditions prevailing on the valuation date. • Long-term inflation - It is the increase of the general level of prices expected in Peru for the long term. • Long-term occupancy rate - It is the expected occupancy level of lessees in the leased properties. • Average growth rate of rental income - It is the rate that expresses the rental income growth and includes growth factors of the industry, inflation rates, stable exchange rate, per capita income and increasing expenses. • Average Net Operating Income (NOI) margin - It is projected from the rental income from leasable areas, by property and marketing income, minus costs related to administration fees, other administrative expenses, insurance, taxes and other expenses. • Discount rate - It reflects the current market risk and the uncertainty associated to obtaining cash flows. The main assumptions used in the valuation and estimation of the market value of investment property are detailed below: US$ / Percentage 2020 2019 Average ERV US$ 82.3 US$ 88.7 Long-term inflation 2.2 % 2.6 % Long-term occupancy rate 98.7 % 99.3 % Average growth rate of rental income 2.4 % 2.6 % Average NOI margin 92.0 % 93.8 % Discount rate 8.7 % 8.7 % Sensitivity analysis - The sensitivity analysis on the valuation of investment property, against changes in factors deemed relevant by Management, is presented below: 2020 2019 S/(000) S/(000) Average growth rate of rental income (basis) - Increase +0.25 % 15,735 16,045 Decrease -0.25 % (15,154 ) (15,306 ) Long-term inflation (basis) - Increase +0.25 % 18,529 15,132 Decrease -0.25 % (17,125 ) (13,906 ) Discount rate (basis) - Increase +0.5 % (44,597 ) (43,733 ) Decrease -0.5 % 52,029 51,703 Likewise, a significant increase (decrease) in the price per square meter of the land lots could result in a significantly higher (lower) fair value measurement. (g) Below are the nominal amounts of the future minimum fixed rental income of the Group’s investment property (operating leases): Year 2020 2019 S/(000) S/(000) Within 1 year 38,264 40,920 After 1 year but not more than 5 years 175,967 149,263 Over 5 years 840,000 689,715 Total 1,054,231 879,898 The minimum rental income is computed considering a period between 20 and 25 years.

In Management’s opinion, there is no evidence of impairment in the Group’s intangible assets as of December 31, 2020, 2019 and 2018. (b) Goodwill In 2017, IFS acquired 99.39 percent of Seguros Sura’s capital stock and 99.42 percent of Hipotecaria Sura’s capital stock. In March 2018, Interseguro merged with Seguro Sura, using the method of absorption, originating the transfer of all the assets and liabilities of Seguros Sura to the absorbing company and extinguishing without having to liquidate. The goodwill resulting from the purchase of Seguros Sura and Hipotecaria Sura represents the future synergies that are expected to arise from the combination of operations, distribution channels, workforce and other efficiencies not included in the intangible assets of the present value of acquired in-force The goodwill recorded by the Group has been allocated to the CGU (cash generated unit) comprised of the merged entity. The recoverable amount for the CGU was determined based on the income approach, specifically the dividend discount model. As of December 31, 2020 and 2019, the key assumptions used for the calculation of fair value are: • Perpetuity growth rate: 4.5%. • Discount rate: 12.5% (2020) and 12.0% (2019) 10-year The discount rate represents the assessment of the CGU specific risks. The discount rate was established considering the Company’s capital structure, the cost of capital coming from the benefits that the Group’s investors expect to obtain, from the specific risk incorporated by applying comparable individual beta factors adapted to the CGU’s debt structure and from the country and market specific risk premiums for the CGU. Beta factors are assessed on an annual basis using available market information. The key assumptions described above can change if the market conditions and the economy change. As of December 31, 2020 and 2019, the Group estimates that the reasonableness of possible changes in these assumptions would not make the recoverable amount of the CGU decrease to an amount lower than its book value. As detailed in Note 2(g), as of December 31, 2019, Hipotecaria Sura has been extinguished; due to this, the decrease in its corresponding goodwill was recorded for an amount of S/2,233,000 in “Other expenses” of the consolidated statement of income; see Note 21.

(b) Subordinated bonds do not have specific guarantees and in accordance with SBS rules, qualify as second level equity (Tier 2) in the determination of the effective equity; see Note 16(f). (c) On September 30, 2020, Interseguro issued subordinated bonds denominated “Third Issuance of the Third Program of Subordinated Bonds Interseguro (Single Series)” for the amount of US$25,000,000, recorded in Section “Transferable Securities and Issuance Programs” of the Public Registry of the Stock Market, under the Third Program of Subordinated Bonds of Interseguro. (d) On June 30, 2020, Interbank placed subordinated bonds called “4.00% Subordinated Notes due 2030” for an amount of US$300,000,000, under Rule 144A and Regulation S of the U.S. Securities Act of 1933 of the United States of America. The issuance date of these bonds was July 8, 2020. This issuance is redeemable, from July 8, 2025, with prior authorization by the SBS, having to pay a redemption price of 100 percent of the issued subordinated bonds. From that date onwards, in case the Bank does not redeem bonds, the interest rate will increase by 371.1 basis points. After July 8, 2025, with prior authorization by the SBS, Interbank will be able to redeem the entirety of the bonds, having to pay a redemption price of 100 percent of the issued subordinated bonds plus the present value of each scheduled coupon payment, discounted at the redemption date. (e) On September 24, 2019, Interbank placed corporate bonds denominated “5.00% Senior Notes due 2026” for S/312,000,000, under Rule 144A and Regulation S of the U.S. Securities Act of 1993 of the United States of America. These bonds were issued on October 1, 2019. (f) On September 25, 2019, Interbank placed corporate bonds denominated “3.05% Note due 2026” for US$400,000,000, under Rule 144A and Regulation S of the U.S. Securities Act of 1993 of the United States of America. These bonds were issued on October 4, 2019. As part of said program, on September 19, 2019, Interbank announced of a buyback offering in cash of the senior bonds denominated “5.750% Senior Notes Due 2020” issued by the Panama Branch; however, until October 2, 2019, only approximately 37.52 percent of the holders had accepted the buyback offering in cash. In this sense, for the remaining bondholders that did not accept the buyback offering, Interbank communicated them its decision to exercise the early redemption option of said instruments; the redemption date was November 4, 2019. In this regard, Interbank incurred in expenses for the partial buyback of the bonds and for the early redemption option amounting to US$12,755,000 (equivalent to approximately S/42,270,000), which were recorded as “Interest for bonds, notes and other obligations” in the caption “Interest and similar expenses” in the consolidated statement of income. (g) In January 2018, Interbank issued corporate bonds called “3.375 Senior Unsecured Notes” for US$200,000,000, under Rule 144A and Regulation S of the U.S. Securities Act of 1993 of the United States of America. Likewise, as part of that program, Interbank made an exchange offer addressed to the holders of the corporate bonds denominated “5.750% Senior Notes due 2020” issued by the Panama Branch, managing to exchange bonds for an amount of US$263,322,000, which generated an exchange premium of approximately US$21,573,000, which are presented together in the caption “Bonds, notes and other obligations” for an amount of US$284,895,000. In this regard, considering the issuance of bonds in January 2018 and the exchange of bonds made, the total balance of the “3.375 Senior Unsecured Notes” amounted to US$484,895,000. The Group concluded that the aforementioned exchange did not generate any substantial modification in the terms and conditions of the financial liability; therefore, it did not recognize a new financial liability. Additionally, according to IFRS 9, the Group reported a gain of approximately US$4,762,000 (equivalent to S/15,286,000), caused by the difference between the present values of both obligations, which were discounted at the effective interest rate of the original financial liability and included in the caption “Interest and similar expenses” of the consolidated statement of income, thus decreasing the interest expenses generated by these issuances. As of December 31, 2020, Interbank maintains fourteen cross-currency swaps for a total of US$441,000,000 (equivalent to approximately S/1,596,861,000), which were designated as cash flow hedges (fourteen cross-currency swaps for US$441,000 equivalent to approximately S/1,461,474,000 as of December 31, 2019); see Note 10(b). Through these operations, part of the issued amount by these bonds was economically converted into Soles at a fixed rate of 4.88 percent. As of December 31, 2020, Management does not intend to redeem these bonds before their maturity date; said situation may change in the future, depending on market conditions. (h) Starting in March 2024, the applicable interest rate will be a floating rate of 3-month In accordance with SBS regulation, this issuance qualifies as second level equity (Tier 2) in the determination of the effective equity; see Note 16(f). As of December 31, 2020, Management does not intend to redeem these bonds before their maturity date; said situation may change in the future, depending on market conditions. (i) From 2018 until July 2027, IFS, on any time, can redeem these bonds, paying a penalty equal to the United States Treasury rate plus 30 basis points. The payment of principal will take place on the maturity date of the bonds or when IFS redeems them. In October 2017, IFS entered a cross currency swap for US$150,000,000 (As of December 31, 2020 and 2019, equivalent to approximately S/543,150,000 and S/497,100,000, respectively), which was designated as a cash flow hedge, see Note 10(b); through this operation part of the issued amount of these bonds was economically converted to Soles at a fix rate of 5.06 percent. As of December 31, 2020, Management does not intend to redeem these bonds before their maturity date; said situation may change in the future, depending on market conditions. (j) Starting in April 2020, the applicable interest rate will be a floating rate of 3-month This issuance qualified as first level equity (Tier 1), nevertheless, the SBS establishes a 17.65 percent limit, which is computed over the capital, reserves and retained earnings pending capitalization of Interbank in the determination of its effective equity; any excess qualified as second level equity (Tier 2); see Note 16(f). In a Board Session held on January 28, 2020, Interbank agreed to redeem the entirety of these instruments. Said redemption was made on April 23, 2020. (k) The international issuances are listed at the Luxembourg Stock Exchange. On the other hand, the local and international issuances include standard clauses of compliance with financial ratios, the use of funds and other administrative matters. As of December 31, 2020 and 2019, the international issuances maintain mainly this clause: “Submit audited financial statements on an annual basis and unaudited financial statements on a quarterly basis (both in Spanish and English)”. In the opinion of Group Management and its legal advisers, this clause has been met by the Group as of December 31, 2020 and 2019. (l) As of December 31, 2020 and 2019, the repayment schedule of these obligations is as follows: Year 2020 2019 S/(000) S/(000) 2020 — 235,128 2021 104,078 — 2022 137,900 136,908 2023 2,171,241 1,988,369 2024 onwards 5,365,532 4,529,885 Total 7,778,751 6,890,290

As of December 31, 2020 and 2019, the regulatory capital required for Interbank, Interseguro and Inteligo Bank (a Subsidiary of Inteligo Group Corp.), is calculated based on the separate financial statement of each Subsidiary prepared following the accounting principles and practices stated by their regulators (the SBS or the Central Bank of the Bahamas, in the case of Inteligo Bank). The regulatory capital required for Interbank, Interseguro and Inteligo Bank is detailed below: Interbank’s regulatory capital - According to Legislative Decree No. 1028 and amendments, Interbank’s regulatory capital must be equal to or higher than 10 percent of the assets and contingent credits weighted by total risk represented by the sum of: the regulatory capital requirement for market risk multiplied by 10, the regulatory capital requirement for operational risk multiplied by 10 and the assets and contingent credits weighted by credit risk. As of December 31, 2020 and 2019, Interbank maintains the following amounts related to the assets and contingent credits weighted by risk and regulatory capital (basic and supplementary): 2020 2019 S/(000) S/(000) Total risk weighted assets and credits 51,451,816 50,673,786 Total regulatory capital 8,742,126 7,679,278 Basic regulatory capital (Level 1) 5,930,657 5,721,707 Supplementary regulatory capital (Level 2) 2,811,469 1,957,571 Global capital to regulatory capital ratio 16.99 % 15.15 % As of December 31, 2020 and 2019, Interbank has complied with SBS Resolutions No.2115-2009, No.6328-2009 and No.14354-2009, “Regulations for the Regulatory Capital Requirement for Operational Risk”, “Market Risk” and “Credit Risk”, respectively, as amended. These resolutions establish, mainly, the methodologies to be applied by financial entities to calculate the assets and credits weighted per type of risk. In July 2011, the SBS issued Resolution No. 8425-2011, which states that financial entities must determine an additional regulatory capital level and develop a process to assess the adequacy of their regulatory capital in relation with their risk profile, which must follow the methodology described in said resolution. The additional regulatory capital requirement shall be equivalent to the amount of regulatory capital requirements calculated for each of the following components: economic cycle, concentration risk, market concentration risk and interest rate risk in the bank book, among others. As of December 31, 2020 and 2019, the additional regulatory capital estimated by Interbank amounts to approximately S/341,328,000 and S/803,717,000, respectively. On March 26, 2020, the SBS issued Resolution No. 1264-2020, establishing that the calculation of regulatory capital requirements for mortgage loans and non-revolving In Group Management’s opinion, Interbank has complied with the requirements established by the aforementioned Resolution. Interseguro’s regulatory capital - In accordance with SBS Resolution No. 1124-2006, and its amendments, Interseguro is required to maintain a level of regulatory capital in order to maintain a minimum equity to support technical risks and other risks that could affect it. The regulatory capital must be higher than the amount resulting from the sum of the solvency net equity, the guarantee fund and the regulatory capital intended to cover credit risks. The solvency net equity is represented by the higher amount between the solvency margin and the minimal capital. As of December 31, 2020 and 2019, the solvency net equity is represented by the solvency margin. The solvency margin is the complementary support that insurance entities must maintain to deal with possible situations of excess claims not foreseen in the establishment of technical reserves. The total solvency margin corresponds to the sum of the solvency margins of each branch in which Interseguro operates. Also, the guarantee fund represents the additional equity support that insurance companies must maintain to deal with the other risks that can affect them and that are not covered by the solvency net equity, such as investment risks and other risks. The monthly amount of said fund must be equivalent to 35 percent of the solvency net equity, calculated in accordance with SBS Resolution No. 1124-2006. As of December 31, 2020 and 2019, Interseguro’s surplus equity is as follows: 2020 2019 S/(000) S/(000) Regulatory capital 1,359,414 1,106,609 Less Solvency equity (solvency margin) 607,841 567,348 Guarantee fund 212,744 198,572 Surplus 538,829 340,689 Inteligo Bank’s regulatory capital - The Central Bank of the Bahamas requires Inteligo Bank to maintain a regulatory capital of not less than 8 percent of its risk weighted assets. Inteligo Bank’s capital ratio as of December 31, 2020 and 2019 is the following: 2019 2018 US$(000) US$(000) Total eligible capital 270,709 238,281 Total risk weighted assets 953,009 964,156 Capital adequacy ratio (in percentage) 28.41 24.71 In Group Management’s opinion, its Subsidiaries have complied with the requirements set forth by the regulatory entities. (g) Reserves - The Board of Directors of IFS session held on April 22, 2020, agreed to constitute reserves for S/500,000,000 charged to retained earnings. The Board of Directors of IFS sessions held on June 25, 2018, and May 9, 2018, agreed to constitute a reserve of up to S/1,000,000,000 charged to retained earnings. (h) Subsidiaries’ legal and special reserves - The Subsidiaries domiciled in Peru are required to establish a reserve equivalent to a certain percentage of their paid-in

Disclosure of Tax situation [Abstract]
Tax situation	17. Tax situation (a) IFS and its Subsidiaries incorporated and domiciled in the Republic of Panama and the Commonwealth of the Bahamas (see Note 2), are not subject to any Income Tax, or any other taxes on capital gains, equity or property. The Subsidiaries incorporated and domiciled in Peru (see Note 2) are subject to the Peruvian Tax legislation; see paragraph (c). Peruvian life insurance companies are exempt from Income Tax regarding the income derived from assets linked to technical reserves for pension insurance and annuities from the Private Pension Fund Administration System. In Peru, all income from Peruvian sources obtained from the direct or indirect sale of shares of stock capital representing participation of legal persons domiciled in the country are subject to income tax. For that purpose, an indirect sale shall be considered to have occurred when shares of stock or ownership interests of a legal entity are sold and this legal entity is not domiciled in the country and, in turn, is the holder — whether directly or through other legal entity or entities — of shares of stock or ownership interests of one or more legal entities domiciled in the country, provided that certain conditions established by law occur. In this sense, the Act states that an assumption of indirect transfer of shares arises when in any of the 12 months prior to disposal, the market value of shares or participations of the legal person domiciled is equivalent to 50 percent or more of the market value of shares or participations of the legal person non-domiciled. non-domiciled (b) Legal entities or individuals not domiciled in Peru are subject to an additional tax (equivalent to 5 percent) on dividends received from entities domiciled in Peru. The corresponding tax is withheld by the entity that distributes the dividends. In this regard, since IFS controls the entities that distribute the dividends, it recognizes the amount of the additional Income Tax as expense of the financial year of the dividends. In this sense, as of December 31, 2020 and 2019, the Company has recorded an expense recovery for S/2,017,000 and expenses for S/36,361,000, respectively, in the caption “Income Tax” of the consolidated statement of income. The recovery recognized in the year 2020 resulted from: (i) the decrease in the percentage of divididends distribution by Interbank in April 2020, as indicated in Note 1(b)(b.3), which generated that IFS recorded in the year 2020 a rebate of the provision constituted as of December 31, 2019, and; (ii) lower recognition of expenses for Income Tax provision over dividends due to a lower income in Interbank for the year 2020. (c) IFS’s Subsidiaries incorporated in Peru are subject to the payment of Peruvian taxes; hence, they must calculate their tax expenses on the basis of their separate financial statements. The Income Tax rate as of December 31, 2020, 2019 and 2018, was 29.5 percent, over the taxable income. (d) The Tax Authority (henceforth “SUNAT”, by its Spanish acronym) is legally entitled to perform tax audit procedures for up to four years subsequent to the date at which the tax return regarding a taxable period must be filed. As of December 31, 2020, the following taxable periods are subject to inspection by the Tax Authority: • Interbank: Income Tax returns for the years 2015 to 2020, and Value-Added-Tax • Interseguro: Income Tax returns for the years 2015, 2017, 2018, 2019 and 2020, and Value-Added-Tax • Hipotecaria Sura Income Tax returns for the years 2015 to 2018, and Value-Added-Tax • Seguros Sura: Income Tax returns for the years 2015 to 2018, and Value-Added-Tax Given the possible interpretations that SUNAT may give to the legislation in effect, up to date it is not possible to determine whether or not any review to be conducted would result in liabilities for the Subsidiaries; any increased tax or surcharge that could arise from possible tax audits would be applied to the results of the period in which such tax increase or surcharge may be determined. Following is the description of the main ongoing tax procedures for the Subsidiaries: Interbank: In April 2004, June 2006, February 2007, June 2007, November 2007, October 2008 and December 2010, Interbank received a number of Tax Determination and Tax Penalty notices corresponding mainly to the Income Tax determination for the fiscal years 2000 to 2006. As a result, claims and appeals were filed and subsequent contentious administrative proceedings were started, with the exception of Income Tax 2006, which is still pending of being filed. Regarding the tax litigations followed by Interbank related to the annual Income Tax returns for the years 2000 to 2006, the most relevant matter subject to discrepancy with SUNAT corresponds to whether the “interest in suspense” are subject to Income Tax or not. In this sense, Interbank considers that the interest in suspense do not constitute accrued income, in accordance with the SBS’s regulations, which is also supported by a ruling by the Permanent Constitutional and Social Law Chamber of the Supreme Court issued in August 2009 and a pronouncement in June 2019. Notwithstanding the foregoing, in February 2018, the Third Transitory Chamber of Constitutional and Social Law of the Supreme Court issued a ruling regarding a third bank that impacted the original estimation regarding the degree of contingency for this discrepancy. Subsequently, in June 2019, the Permanent Chamber of Constitutional and Social Law of the Supreme Court, in a case followed by another financial entity, but identical to Interbank’s case, ruled in favor of the tax treatment over the interest in suspense followed by said entity. Likewise, on July 6, 2020 and December 28, 2020, the Permanent Chamber of Constitutional and Social Law of the Supreme Court notified to Interbank its ruling regarding Interbank’s Income Tax 2003 and prepaid income tax for the year 2003, declaring groundless the cassation appeals filed by SUNAT and the MEF, thus reaffirming the position held by Interbank regarding that interest in suspense does not constitute taxable income. As of December 31, 2020, the tax liability requested for this concept and other minor contingencies amounts to approximately S/382,000,000, which includes the tax, fines and interest arrears, of which S/293,000,0000 corresponded to interest in suspense and S/89,000,000 corresponded to other minor repairs. From the tax and legal analysis performed, Interbank´s Management and its external legal advisers consider that there exists sufficient technical support for the prevailing of Interbank’s position; as consequence, no provision has been recorded for this contingency as of December 31, 2020 and 2019. On February 3, 2017, SUNAT closed the audit process corresponding to the Income Tax for the year 2010. Interbank paid the debt under protest and filed a claim procedure. Subsequently, on November 6, 2018, SUNAT closed again the audit process corresponding to the Income Tax 2010, which had been reopened due to invalidity; Interbank filed a claim procedure and afterwards a tax appeal. Currently, the appeal is pending resolution by the Tax Court. On January 14, 2019, Interbank was notified of the Determination and Penalty Resolutions corresponding to the audit of the Income Tax for the fiscal year 2013. To such date, the tax debt requested by SUNAT amounts to approximately S/50,000,000. The main concept observed was the deduction of loan write-offs without proof by the SBS. As of December 31, 2020 and 2019, the tax debt requested for this concept and other minor contingencies amounts to approximately S/40,000,000 and S/39,000,000, respectively, which comprises the tax, penalties and moratorium interest. On April 26, 2019, SUNAT notified about the commencement of the definitive audit process on Income Tax withholdings of non-domiciled On September 11, 2019, SUNAT notified Interbank about the beginning of the definitive audit process on Income Tax corresponding to the year 2015. To date, said audit is under process and SUNAT has not issued any resolutions. On December 12, 2019, SUNAT notified the Bank about the beginning of the definitive audit process on Income Tax corresponding to the year 2015. To date, said audit is under process. On July 31, 2020, Interbank was notified of the Determination and Penalty Resolutions corresponding to the audit of the Income Tax for the fiscal year 2012. To date, the tax debt requested by SUNAT amounted to approximately S/13,000,000. On August 27, 2020, Interbank filed a complaint appeal which is pending resolution. On February 12, 2021, Interbank was notified with the Resolution of Compliance related to the Income Tax and prepaid income tax of the year 2006 (related to litigations about interest in suspense). Through such Resolution, SUNAT increased the alleged tax debt from S/1,000,000 to S/35,000,0000 , because as a consequence of such Resolution of Compliance certain deductions previously recognized by SUNAT were unrecognized. Interbank´s Management and its legal advisors will appeal such Resolution before the Tax Court, and in its opinion, no additional liabilities for Interbank will result as consequence of this matter. In the opinion of Interbank´s Management and its legal advisors, any eventual additional tax settlement would not be significant for the financial statements as of December 31, 2020 and 2019. Interseguro: On January 4, 2019, Interseguro was notified through a Tax Determination notice about the partial audit of the Income Tax for non-domiciled In the opinion of Management and its legal advisers, any eventual additional tax would not be significant for the financial statements as of December 31, 2020 and 2019. (e) For the purpose of determining the Income Tax, the transfer prices of transactions with related companies and with companies domiciled in countries or territories that are non-cooperating Through Legislative Decree No. 1312, published on December 31, 2016, the formal obligations for entities included within the scope of application of transfer pricing are modified, thus incorporating three new information requirements: the first is a Local Report; the second is a Master Report; and the third is a Country Report. The first entered into effect since 2017 for the operations that occurred during 2016 and the last two since 2018 for the operations that have occurred since the fiscal year 2017. (f) Through Legislative Decree No.1381, published on August 24, 2018, it was incorporated in the Income Tax Act the concept of “non-cooperating” As of December 31, 2019 Interbank maintained a branch in Panama, a country that is considered “non-cooperating”, (g) In July 2018, Act No. 30823 was published, whereby the Congress delegated power to the Executive Branch to legislate on various issues, including tax and financial matters. In this sense, the main tax regulations issued are the following: (i) Beginning on January 1, 2019, the treatment applicable to royalties and remuneration for services rendered by non-domiciled (ii) The rules that regulate the obligation of legal persons and/or legal entities to inform the identification of their final beneficiaries (Legislative Decree No. 1372) were established. These rules are applicable to legal entities domiciled in the country, in accordance with the provisions of Article 7 of the Income Tax Act, and legal entities established in the country. The obligation covers non-domiciled (iii) The Tax Code was amended with the purpose of offering taxpayers more assurance regarding the application of the general anti-avoidance rule (Rule XVI of the Preliminary Title of the Tax Code); as well as to provide SUNAT with tools for its effective implementation (Legislative Decree No.1422). As part of this amendment, a new assumption of joint and several liability is envisaged, when the tax debtor is subject to the application of the measures provided by Rule XVI in the event that presumed tax avoidance cases are detected; in such case, the joint and several liability shall be attributed to the legal representatives provided that they have collaborated with the design or approval or execution of actions or situations or economic relations viewed as tax avoidance in Rule XVI. In the case of companies that have a Board of Directors, it is up to this corporate body to define the tax strategy of the entity, having to decide on the approval or not of actions, situations or economic relations to be carried out within the framework of tax planning, this power being non-delegable. Likewise, it has been established that the application of Rule XVI, regarding the re-characterization (iv) Amendments to the Income Tax Act were included, effective as of January 1, 2019, to improve the tax treatment applicable to the following (Legislative Decree No. 1424): • Income obtained from the indirect transfer of shares of stock or capital representing participations of legal persons domiciled in the country. Among the most significant changes is the inclusion of a new indirect sale assumption, which is triggered when the total amount of the shares of the domiciled legal entity whose indirect disposal is made is equal to or higher than 40,000 Taxation Units. • Permanent establishments of sole proprietorships, companies and entities of any nature incorporated abroad. For this purpose, new cases of permanent establishment have been included, among them, when the rendering of services in the country occurs, with respect to the same project, service or related one, for a period that exceeds 183 calendar days in total within any period of twelve months. • The system of credits against Income Tax for taxes paid abroad, to be included in the indirect tax credit (corporate tax paid by foreign subsidiaries) as credit applicable against the Income Tax of domiciled legal persons, in order to avoid double economic taxation. • The deduction of interest expenses for the determination of corporate Income Tax. In the years 2020 and 2021, it shall be applicable the debt limit set at up to three times the net equity as of December 31 of the previous year will be applicable, both to loans with related parties, and to loans with third parties contracted since September 14, 2018. Beginning in 2022, the limit for the deduction of financial expenses shall be equivalent to 30 percent of the entity’s EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization). (v) Regulations have been established for the accrual of income and expenses for tax purposes beginning on January 1, 2019 (Legislative Decree No. 1425). Until 2018, there was no rule definition of this concept, so in many cases accounting rules were used for its interpretation. In general terms, with the new criterion, for the purpose of determining the Income Tax, it shall be considered whether the substantial events for the generation of income or expense agreed upon by the parties have occurred, provided they are not subject to a subsequent condition, in which case the recognition shall take place when it is fulfilled and when collection or payment is to take place will not be taken into account; and, if the determination of the consideration depends on a future action or event, the total or part of the corresponding income or expense will be deferred until that action or event occurs. (h) Supreme Decree No. 430-2020-EF, Considering that, said Regulation established the concepts that the financial entities must report to SUNAT, which are, among others, cumulative balances and/or amounts, averages or highest amounts and the returns generated in the accounts during the reporting period that are equal or higher than S/30,800 in said period. The information shall be provided to SUNAT semi-annually through informative declarations containing monthly information. (i) Law No. 31106 extends until December 31, 2023, the validity of all exemptions in force to date contained in Article 19 of the Income Tax Act. On this matter, among the aforementioned extended exemptions that are applicable or related to Interbank’s operations are subparagraph i) of Article 19 which indicates that shall be exempted any type of fixed or variable interest rate, in local or foreign currency, that is paid for any deposit or levy pursuant to the General Act of the Banking and Insurance System and Organic Act of the Superintendence of Banking, Insurance and Private Pension Funds, Law No. 26702, as well as the capital increases of said deposits and levies, in local or foreign currency, except when said income constitute third category income.

Guarantees vary and include deposits in financial institutions or other assets. Taking into account that most of the contingent operations are expected to expire without the Group having to disburse cash, the total committed amounts do not necessarily represent future cash requirements.

Financial risk management	30. Financial risk management It comprises the management of the main risks, that due to the nature of their operations, IFS and its Subsidiaries are exposed to; and correspond to: credit risk, market risk, liquidity risk, insurance risk and real estate risk. • Credit risk: possibility of loss due to inability or lack of willingness to pay of debtors, counterparts or third parties bound to comply with their contractual obligations. • Market risk: probability of loss in positions on and off the consolidated statement of financial position derived from variations in market conditions; it generally includes the following types of risk: exchange rate; fair value by interest rate, price, among others. • Liquidity risk: possibility of loss due to noncompliance with the requirements of financing and fund application that arise from mismatches of cash flows. • Insurance risk: possibility that the actual cost of claims and payments will differ from the estimates. • Real estate risk: possibility of significant loss in rental income due to the insolvency of the lessee or, a decrease in the market value of real estate investments. In order to manage the risks detailed above, every Subsidiary of the Group has a specialized structure and organization in their management, measurement systems, as well as mitigation and coverage processes, according to specific regulatory needs and requirements for the development of its business. The Group and its Subsidiaries, mainly Interbank, Interseguro and Inteligo Bank, operate independently but in coordination with the general provisions issued by the Board of Directors and Management of IFS; however, the Board of Directors and Management of IFS are ultimately responsible for identifying and controlling risks. The Company has an Audit Committee comprised of three independent directors, pursuant to Rule 10A-3 Also, the Audit Committee is responsible of assisting the Board of Directors in the monitoring and supervising, thus helping to ensure: • The quality and comprehensiveness of IFS’s financial statements, including its disclosures. • The existence of adequate procedures to assess, objectively and periodically, the effectiveness of the internal control system over the financial report. • The compliance with the legal and regulatory framework. • The qualification and independence of external auditors. • The performance of external auditors. • The implementation by Management of an adequate internal control system, in particular the internal control system over the financial report. Likewise, the Company has an Internal Audit Division which is responsible for monitoring the key processes and controls to ensure an adequate low risk control according to the standards defined in the Sarbanes Oxley Act. Management is responsible of the preparation, presentation and comprehensiveness of the Group’s consolidated financial statements, the suitability of the accounting principles and information policies it uses, the establishment and upkeeping of the internal control over the financial information, as well as the facilitation of communications among external auditors, IFS’s managers and the Board of Directors. (a) Structure and organization of risk management - The Group’s risk management structure and organization for each of its Subsidiaries is as follows: (i) Interbank - Board of Directors Interbank’s Board of Directors is responsible for establishing an appropriate and integral risk management and promoting an internal environment that facilitates its development. The Board is continuously informed about the exposure degree of the various risks managed by Interbank. The Board has created several specialized committees to which it has delegated specific tasks in order to strengthen risk management and internal control. Audit Committee The Audit Committee’s main purpose is to monitor that the accounting financial reporting processes are appropriate, as well as to evaluate the activities performed by the auditors, both internal and external. The Committee is comprised of three members of the Board and the Chief Executive Officer, the Internal Auditor, the Vice-President of Corporate and Legal Affairs and other executives may also participate therein, when required. The Committee meets at least six times a year in ordinary sessions and informs the Board about the most relevant issues discussed. Comprehensive Risk Management Committee The Comprehensive Risk Management Committee (“GIR”, by its Spanish acronym) is responsible for approving the policies and organization for comprehensive risk management, as well as the amendments to said policies. This Committee defines the level of tolerance and the exposure degree to risk that Interbank is willing to assume in its business and also decides on the necessary actions aimed at implementing the required corrective measures in case of deviations from the levels of tolerance to risk. The Committee is comprised of two Directors, the Chief Executive Officer and the Vice-Presidents. The Committee reports monthly to the Board of Directors the main issues it has discussed and the resolutions taken in the previous meeting. Assets and Liabilities Committee The main purpose of the Assets and Liabilities Committee (“ALCO”) is to manage the financial structure of the statement of financial position of Interbank, based on profitability and risk targets. The ALCO is also responsible for the proposal of new products or operations that contain components of market risk. Likewise, it is the communication channel with the units that generate market risk. The ALCO meets monthly and it is comprised of the Chief Executive Officer, the Vice-Presidents of Risks, Commercial, Finance, Operations, Distribution Channels, Capital Market and the Manager of Treasury / Position Desk. Internal Audit Division - Risk management processes of Interbank are monitored by the Internal Audit Division, which examines both the adequacy of the procedures and the compliance with them. The Internal Audit Division discusses the results of all assessments with Management and reports its findings and recommendations to the Audit Committee and Board of Directors. (ii) Interseguro - Board of Directors The Board of Directors is responsible for the overall approach to risk management and it is responsible for the approval of the policies and strategies currently used. The Board of Directors provides the principles for overall risk management, as well as the policies prepared for specific areas, such as foreign exchange risk, interest rate risk, credit risk and the use of derivative and non-derivative Audit Committee The main purpose of the Audit Committee is to monitor that the accounting and financial reporting process are appropriate, as well as to assess the activities performed by External and Internal Auditors. The Audit Committee is comprised of three Board members who do not fulfil any executive position within Interseguro, being at least one of them an Independent Director, who leads the Committee and cannot lead any other Committee within Interseguro. The Committee sessions can be attended by the Chief Executive Officer, the Audit Manager, the External Auditors and other executives when required. The Committee meets at least six times a year in ordinary sessions and informs the Board on the most relevant issues it has addressed. Risk Committee The Risk Committee is a corporate body created by the Board. It is responsible of defining the business risk limits of Interseguro through the approval of risk policies and the corrective measures needed to maintain adequate levels of risk tolerance. The Risk Committee is comprised of four Board members, the Risk Manager and the Chief Executive Officer. Investment Committee The Investment Committee is responsible of approving the limits of each security or real estate that may be included in Interseguro’s investment portfolio. This Committee is comprised of several Board Members, the Chief Executive Officer and the Vice-President of Investments. Internal Audit Division Risk management processes throughout Interseguro are monitored by the Internal Audit Division, which reviews and assesses the design, scope and functioning of the internal control system and verifies the compliance of the legal requirements, policies, standards and procedures. The Internal Audit Division discusses the results of all assessments with Management and reports its findings and recommendations to the Audit Committee and Board of Directors. (iii) Inteligo Bank - Inteligo Bank’s Board of Directors is responsible for the establishment and monitoring of the risk administration policies. In order to manage and monitor the various risks Inteligo Bank is exposed to, the Board of Directors has created the Credit and Investment Committee, the Assets and Liabilities Committee, the Credit Risk Committee and the Audit Committee. Due to the Covid-19 (b) Risk measurement and reporting systems - The Group uses different models and rating tools. These tools measure and value the risk with a prospective vision, thus allowing the making of better risk decisions in the different stages or life cycle of client or product. Said models and tools are permanently monitored and periodically validated in order to assure that the levels of prediction and performance are being maintained and to make the corrective actions or adjustments, when needed. (c) Risk mitigation and risk coverage - In order to mitigate its exposure to the various financial risks and provide adequate coverage, the Group has established a series of measures, among which the following stand out: • Policies, procedures, methodologies, models and parameters aimed to allow for the identification, measurement, control and reporting of diverse financial risks; • Review and assessment of diverse financial risks, through specialized units of risk screening; • Timely monitoring and tracking of diverse financial risks and their maintenance within a defined tolerance level; • Compliance with regulatory limits and establishment of internal limits for exposure concentration; and • Procedures for guarantees management. Likewise, as part of its comprehensive risk management, in certain circumstances the Group uses derivative financial instruments to mitigate its risk exposure, which arises from the variations in interest rates and foreign exchange rates. (d) Risk concentration - Through its policies and procedures, the Group has established the guidelines and mechanisms needed to prevent excessive risk concentration. In case any concentration risk is identified, the Group works with specialized units that enable it to control and manage said risks. 30.1 Credit risk (a) The Group opts for a credit risk policy that ensures sustained and profitable growth in all its products and business segments it operates. In doing so, it applies assessment procedures for the adequate decision-making, and uses tools and methodologies that allow the identification, measurement, mitigation and control of the different risks in the most efficient manner. Likewise, the Group incorporates, develops and reviews regularly management models that allow an adequate measurement, quantification and monitoring of the loans granted by each business unit and also encouraging the continuous improvement of its policies, tools, methodologies and processes. Additionally, as consequence of the Covid-19 (b) The Group is exposed to credit risk, which is the risk that a counterparty causes a financial loss by failing to comply with an obligation. Credit risk is the most important risk for the Group’s business; therefore, Management carefully manages its exposure to credit risk, which arise mainly in lending activities that lead to loans and investment activities that contribute with securities and other financial instruments to the Group’s asset portfolio. There is also credit risk in the financial instruments out of the consolidated statement of financial position, such as contingent credits (indirect loans), which expose the Group to risks similar to those of direct loans, being mitigated with the same control processes and policies. Likewise, credit risk arising from derivative financial instruments is, at any time, limited to those with positive fair values, as recorded in the consolidated statement of financial position. As of the date of the consolidated statement of financial position and under IFRS 9, impairment allowances are established for expected credit losses. Significant changes in the economy or in the particular situation of an economic sector that represents a concentration in the Group’s portfolio could result in losses that are different from those provisioned for as of the date of the consolidated statement of financial position. The Group structures the levels of credit risk it undertakes by placing limits on the amount of risk accepted in relation to one borrower or groups of borrowers, geographical and industry segments. Said risks are monitored on a revolving basis and subject to continuous review. The Group’s exposure to credit risk is managed through the regular assessment of debtors and their potential capability to pay the principal and interest of their obligations, and through the change in exposure limits, when appropriate. The exposure to credit risk is also mitigated, in part, through the obtaining of personal and corporate collateral. Nevertheless, there is a significant part of the financial instruments where said collateral cannot be obtained. Following is a description of the procedures and policies related to collateral management and valuation of collateral. Policies and procedures for management and valuation of guarantees - Collateral required for financial assets other than the loan portfolio are determined according to the nature of the instrument. However, debt instruments, treasury papers and other financial assets are in general not guaranteed, except for securities guaranteed with similar assets and instruments. The Group has policies and guidelines established for the management of collateral received to back loans granted. The assets that guarantee loan operations bear a certain value prior to the loan approval and the procedures for their updating are described in the internal rules. In order to manage guarantees, the Group operates specialized divisions for the establishment, management and release of guarantees. Collateral that backs loan operations include different goods, property and financial instruments (including cash and securities). Their preferential status depends on the following conditions: • Easy convertibility into cash. • Proper legal documentation, duly registered with the corresponding public registry. • Non-existence • Their fair value must be updated. Long-term loans and fundings granted to corporate entities are generally guaranteed. Consumer loans granted to small companies are not generally guaranteed. Management monitors the fair value of collateral, and with the purpose of mitigating credit losses, requests additional collateral to the counterparty as soon as impairment evidence exists. The proceeds from the settlement of the collateral obtained are used to reduce or repay the outstanding claim. In the case of derivative financial instruments, the Group maintains strict control limits on net open derivative positions (the difference between purchase and sale contracts), both in amount and term. The amount subject to credit risk is limited to the current fair value of instruments that are favorable to the Group (for example, an asset when its fair value is positive), which in relation to derivatives is only a small fraction of the contract, or notional amount used to express the volume of instruments outstanding. This credit risk exposure is managed as part of the overall lending limits with customers, together with potential exposures from market movements. Collateral or other securities are not usually obtained for credit risk exposures on these instruments. Settlement risk arises in any situation where a payment in cash, securities or equity is made in the expectation of a corresponding receipt in cash. Daily settlement limits are established for each counterparty in order to cover the aggregate of all settlement risk arising from the Group’s market transactions on any single day. (c) Maximum exposure to credit risk - As of December 31, 2020 and 2019, Management estimates that the maximum credit risk to which the Group is exposed is represented by the book value of the financial assets which show a potential credit risk and consist mostly of deposits in banks, inter-bank funds, investments, loans (direct and indirect), without considering the fair value of the collateral or guarantees, derivative financial instruments transactions, receivables from insurance transactions and other monetary assets. In this sense, as of December 31, 2020 and 2019, the main captions were formed as follows: • 89.5 percent and 80.4 percent, respectively, of cash corresponds to amounts deposited in the Group’s vaults or in the BCRP; • 85.5 percent and 89.3 percent, respectively, of the loan portfolio is classified into the two lower credit risk categories defined by the Group under IFRS 9 (high and standard grade); • 88.4 percent and 91.8 percent, respectively, of loans is deemed non-past-due non-impaired; Covid-19, • 89.0 percent and 89.8 percent, respectively, of investments at fair value through other comprehensive income and investments at amortized cost have at least an investment grade (BBB- • 97.6 percent and 97.7 percent of accounts receivable from insurance premiums and leases of the investment properties is deemed non-past non-impaired. • In addition, as of December 31, 2020, the Group holds loans (direct and indirect) and investments in fixed income instruments issued by entities related to the infrastructure sector that, in recent years, have been exposed to local and international events, for an amount of approximately of S/1,073,875,000 (S/225,373,000 in direct loans and S/848,502,000 in indirect loans) and S/850,003,000, respectively (S/808,290,000 (S/186,095,000 in direct loans and S/622,195,000 in indirect loans) and S/928,742,000, respectively, as of December 31, 2019). (d) Impairment assessment for loan portfolios - The main objective of the impairment requirements is to recognize expected credit losses during the average life of financial instruments when there has been a significant increase in credit risk after the initial recognition — as evaluated on a collective or individual basis — considering all reasonable and sustainable information, including that which refers to the future. If the financial instrument does not show a significant increase in credit risk after the initial recognition, the provision for credit losses shall be calculated as 12-month Under some circumstances, entities may not have reasonable and sustainable information available without disproportionate effort or cost to measure the expected credit losses during the lifetime of the asset on an individual instrument basis. In that case, expected credit losses during the asset’s lifetime shall be recognized on a collective basis considering information about the overall credit risk. The financial assets for which the Group calculates the expected loss under a collective assessment include: • All direct and indirect (contingent) loans related to stand-by • Debt instruments measured at amortized cost or at fair value through other comprehensive income. The expected credit loss is estimated collectively for each loan portfolio with shared similar risk characteristics. Not only default indicators, but all information such as: macroeconomic projections, type of instrument, credit risk ratings, types of guarantees, date of initial recognition, remaining time to maturity, among other indicators. For the collective impairment assessment, the financial assets are grouped based on the Group’s internal credit rating system, which considers credit risk characteristics, such as: type of asset, economic sector, geographical location, type of guarantee, among other relevant factors. Expected losses are calculated under the identification and multiplication of the following risk parameters: • Probability of Default (PD): It is the likelihood of a default over a particular time horizon that a counterpart will be unable to meet its debt obligations and with it is cataloged as default. • Loss Given Default (LGD): Measures the loss in percentage terms on total exposure at default (see Exposure at default). • Exposure at Default (EAD): Represents the total value that the Group can lose upon default of a counterpart. (d.1) Definition of default: In accordance with IFRS 9, the Group determines that there is default on a financial asset when: • The borrower is unlikely to pay their credit obligations to the Group in full, without recourse by the Group to actions such as realizing guarantee (if applicable); or • The borrower is past due by more than 90 days on any material credit obligation to the Group. In assessing whether a borrower presents default, the Group considers the following indicators: • Qualitative: contracts in judicial and prejudicial proceedings. • Quantitative: contracts in default for more than 90 days. • Based on data prepared internally and obtained from external sources such as: • Significant changes in indicators of credit risk • Significant changes in external market indicators • Real or expected significant change in the external and/or internal credit rating • Existing or forecast adverse changes in the business, economic or financial conditions that are expected to cause a significant change in the borrower’s ability to meet their debt obligations • Real or expected significant change in the operating results of the borrower • Existing or future adverse changes in the regulatory, economic or technological environment of the borrower that results in a significant change in their ability to meet their debt obligations. Likewise, losses recognized in the period are affected by several factors, such as: • Financial assets moving from Stage 1 to Stage 2 or Stage 3 because there has been a significant increase in their risk since initial recognition or they present impairment at the analysis date, respectively. As a result, lifetime expected losses are calculated. • Impact on the measurement of expected losses due to changes in PD, EAD and LGD resulting from the update of the inputs used. • Impact on the measurement of expected losses due to changes in the models and assumptions used. • Additional provisions for new financial instruments reported during the period. • Periodic reversion of the discount of expected losses due to the passage of time, as they are measured based on the present value. • Financial assets written off during the period. • Exchange difference arising from financial assets denominated in foreign currency. (d.1.1) Internal rating and PD: The Group’s loans are segmented into homogeneous groups with shared similar credit risk characteristics as detailed below: • Personal Banking (credit cards, mortgages, payroll loans, consumer loans and vehicular loans) • Small Business Banking (segments S1, S2 and S3) • Commercial Banking (Corporate, Institutional, Companies and Real estate) In the case Interbank, Credit Risk Department determines its risk level according to the following classification, as of December 31, 2020 and 2019: 2020 Banking Segment High grade PD less than or equal Standard grade PD range (*) Grade lower than standard PD equal to or higher than (*): Credit card 8.01% 8.02% - 20.72% 20.73% Mortgage 1.98% 1.99% - 7.41% 7.42% Payroll loans 2.27% 2.28% - 5.58% 5.59% Personal Banking Consumer 10.04% 10.05% - 23.77% 23.78% Vehicular 3.95% 3.96% - 12.62% 12.63% Segments S1 and S2 8.73% 8.74% - 21.12% 21.13% Small Business Banking Segments S3 6.37% 6.38% - 17.13% 17.14% Corporate 1.67% 1.67% 1.67% Commercial Banking Institutional 0.42% 0.42% 0.42% Companies 3.09% 3.10% - 8.61% 8.62% Real estate 6.33% 6.33% 6.33% 2019 Banking Segment High grade PD less than or equal to: Standard grade PD range Grade lower than standard PD equal to or higher than: Credit card 9.48% 9.49% - 20.77% 20.78% Mortgage 2.17% 2.18% - 7.38% 7.39% Payroll loans 3.61% 3.62% - 8.27% 8.28% Personal Banking Consumer 8.26% 8.27% - 19.63% 19.64% Vehicular 3.56% 3.57% - 10.90% 10.91% Segments S1 and S2 6.01% 6.02% - 16.11% 16.12% Small Business Banking Segments S3 3.26% 3.27% - 7.91% 7.92% Corporate 1.80% 1.81% - 4.56% 4.57% Commercial Banking Institutional 0.50% 0.50% 0.50% Companies 2.23% 2.24% - 5.34% 5.35% Real estate 4.46% 4.47% - 7.11% 7.12% (*) It is worth mentioning that the probability of default indicated are exclusively those determined by the statistical model and, therefore, do not include the subsequent adjustments to the model that have been originated as consequence of the pandemic, see further detail in 30.1 (d.6) The main objective is to generate statistical models that allow forecasting the applicant’s level of credit risk. The development of these models incorporates both qualitative and quantitative information, as well as client specific information that may affect their performance. These rating models are monitored on a regular basis because with the passage of time some factors may have a negative impact on the model’s discriminating power, and stability due to changes in the population or its characteristics. Each rating has an associated PD, which is adjusted to incorporate prospective information. This is replicated for each macroeconomic scenario, as appropriate. To calculate the PD, two differentiated methodologies have been developed, which are described below: • Transition matrixes Its objective is to determine the probability of default over a 12-month • Default ratio Its objective is to determine the probability of default over a 12-month Given the nature of the portfolios and the availability of historical information, the method to estimate the PD for each portfolio is presented below: Banking / Segments Transition matrix Default ratio Personal banking: Credit cards X Mortgage X Payroll loans X Consumer X Vehicular X Small business banking X Commercial banking Corporate X Institutional X Companies X Real estate X Likewise, Interbank has implemented a system to monitor its commercial sector clients in a more personalized way, based on warnings, changes in rating, reputation problems, among others. At each reporting date, for indirect loans (contingent), as happens for direct loans, the expected loss is calculated depending on the stage in which each operation is located; that is, if it is in Stage 1, the expected loss is calculated with a 12-month The Group considers the changes in credit risk based on the probability that the obligor will fail to comply with the loan agreement. As of December 31, 2020 and 2019, the Group holds stand-by The criteria established to assign the risk to each one of the operations that are evaluated under an individual evaluation use the following combination of factors: quantitative, qualitative and financial. To estimate the PD for the lifetime of a financial asset, a transformation to a 12-month 12-month At Inteligo Bank, both for Personal Banking and Commercial Banking, the internal model developed (scorecard) assigns 5 levels of credit risk: low, medium low, medium, medium high, and high. This methodology evaluates the scoring, increase or decrease of risks, taking into consideration the loan structure and the type of client; therefore, there is one scorecard for Personal Banking and another for Commercial Banking. (d.2) Loss Given Default (LGD): It is an estimated loss in case of default. It is the difference between contractual cash flows due and those expected to be received, including guarantees. Generally, it is expressed as an EAD percentage. In the case of Interbank, the calculation of the LGD has been developed under three differentiated methods, which are described below: • Closed recoveries Those in which a client entered and left default (due to debt settlement, application of penalty or refinancing) over a course of up to 65 months. • Open recoveries Those in which a client entered and did not manage to exit default over a course of up to 65 months. This method identifies the adjustment factor that allows to simulate the effect of a closed recovery process. Thus, a recovery curve is built from the information of closed recovery processes and a recovery rate curve is estimated based on the number of months of each process. This methodology is applied to the Mortgage and Commercial Banking loan portfolios. In the case of Inteligo Bank, for those credits that are classified in Stage 1 or Stage 2 at the reporting date, the regulatory recoveries of the Central Bank of the Bahamas and the Superintendence of Banks of Panama are used, using stressed scenarios for each type of guarantee. (d.3) Exposure at default (EAD): Exposure at default represents the gross carrying amount of financial instruments subject to impairment, which involves both the client’s ability to increase exposure as default approaches and possible early repayments. To calculate the EAD of a loan in Stage 1, potential default events are evaluated over a 12- A calculation methodology has been developed for those portfolios that present a defined schedule, differentiating those transactions that consider prepayment and those that do not consider prepayment; and another methodology that is based on building the credit risk factor for those portfolios that allow the client the ability to use a line of credit (revolving products) and, therefore, the percentage of additional use of the credit line that the client could use in the event of a default must be calculated. (d.4) Significant increase in credit risk: The Group has established a framework that incorporates quantitative and qualitative information to determine whether the credit risk on a financial instrument has significantly increased since initial recognition, both for loans and investments. The framework is aligned with the Group’s internal credit risk management process. In certain cases, using its expert credit judgment and, where possible, with relevant historical experience, the Group may determine that an exposure has experienced a significant increase in credit risk when certain qualitative indicators that may not be captured by a timely quantitative analysis. At each reporting date, expected losses are calculated depending on the stage of each loan, as each one is evaluated with a different life period. • Stage 1 - 12-month 12-month • Stage 2 - Lifetime expected losses are calculated for the entire remaining life of the asset. For operations with payment schedule, they are calculated in each year of remaining life by multiplying the following risk parameters: 12-month • Stage 3 - Expected losses are calculated by multiplying the PD (equal to 100 percent) by the client’s LGD and the balance as of the reporting date. The Group classifies the operations with a significant increase in the risk of each portfolio such as marked refinanced operations, operations with arrears longer than 30 days (for all portfolios except Mortgages that considers arrears longer than 60 days), or operations marked “Leave” or “Reduce” in the surveillance system for the Commercial Banking portfolio. Likewise, the evaluation of the significant risk increase is made by comparing the 12-month 12-month The Group periodically evaluates the following warning signs and criteria to assess whether the placement presents a significant increase in credit risk (Stage 2): • Rescheduled loans. • Infractions to the covenants. • Forced interventions by governments in the primary and secondary markets of obligors. • Involvement of the borrower in illicit, political and fraud business. • Impairment of guarantees (underlying assets). • Arrears or short and frequent failures to pay installments. • Significantly adverse macroeconomic, regulatory, social, technological and environmental changes. • Other assessments and/or warnings (financial statements, EBIT evaluation, financial indicators by industry, regulatory criteria, others). On the other hand, the Group monitors the effectiveness of the criteria used to identify significant increases in credit risk through periodic reviews to confirm that: • Criteria are able to identify significant increases in credit risk before an exposure is in default; • Criteria do not align with point in time (PiT) when an asset is more than 30 days past due. In particular, as consequence of

Financial assets included in Level 1 are those measured on the basis of information that is available on the market, to the extent that their quoted prices reflect an active and liquid market and that are available in some centralized trading mechanism, trading agent, price supplier or regulatory entity. Financial instruments included in Level 2 are valued based on the market prices of other instruments with similar characteristics or with financial valuation models based on information of variables observable in the market (interest rate curves, price vectors, etc.). Financial assets included in Level 3 are valued by using assumptions and data that do not correspond to prices of operations traded on the market. The valuation requires Management to make certain assumptions about the model variables and data, including the forecast of cash flow, discount rate, credit risk and volatility. During the year 2020, there were transfers of certain financial instruments from Level 1 to Level 2 for the amount of S/4,116,507,000, because they stopped being actively traded during the year and, therefore, fair values were obtained by using observable market data. There were no transfers of financial instruments from Level 3 to Level 1 or Level 2 or viceversa. During the year 2019, there were neither transfers of financial instruments from Level 3 to Level 1 or Level 2, nor from Level 1 to Level 2. The table below presents a description of significant unobservable data used in valuation: Valuation technique Significant unobservable Valuation Sensitivity of inputs to fair value Royalty Pharma DCF Method NAV 215.19 10 percent increase (decrease) in the NAVs would result in increase (decrease) in fair value by S/10,754,000.

Equity method — According to credit risk 500 basis points increase (decrease) in the discount rate would result in a decrease in fair value of S/1,811,000. The Group determined the fair values of investments included in Level 3 mainly by using methods such as the discounted cash flow, comparable multiples and/or equity method. Starting in 2020, the Group performed changes in the determination of the estimates for the fair value of these investments considering the nature of themselves, as well as the underlying assets and the information to which it had access on the valuation date; concluding that the best valuation method for these investments is the use of the net asset value (“NAV”). It should be noted that the change in this estimate did not have a significant impact with respect of the valuation as of December 31, 2019.

Based on this evaluation, allowances are taken into account for the estimated losses of these loans. As of December 31, 2020 and 2019, the book value of loans, net of allowances, was not significantly different from the calculated fair values. (ii) Instruments whose fair value approximates their book value: For financial assets and financial liabilities that are liquid or have short-term maturity (less than 3 months) it is assumed that the carrying amounts approximate to their fair values. This assumption is also applied to demand deposits, savings accounts without a specific maturity and variable-rate financial instruments. (iii) Fixed-rate financial instruments: The fair value of fixed-rate financial assets and financial liabilities at amortized cost is determined by comparing market interest rates when they were first recognized with current market rates related to similar financial instruments for their remaining term to maturity. The fair value of fixed interest rate deposits is based on discounted cash flows using market interest rates for financial instruments with similar credit risk and maturity. For quoted debt issued, the fair value is determined based on quoted market prices. When quotations are not available, a discounted cash flow model is used based on the yield curve of the appropriate interest rate for the remaining term to maturity.

Foreign currency translation	(a) Foreign currency translation - Functional and presentation currency: The Group has determined that its functional and presentation currency is the Sol, because it reflects the economic substance of the underlying events and circumstances relevant to most of the Group’s entities, insofar as its main operations and/or transactions, such as loans granted, financing obtained, sale of insurance premiums, interest and similar income, interest and similar expenses and an important percentage of purchases are established and settled in Soles; in addition, it corresponds to the functional currency to most of the Subsidiaries; except for Inteligo Bank, whose functional currency is the US Dollar. Because Inteligo Bank has a functional currency different from the Sol, its balances were translated for consolidation purposes using the methodology established by IAS 21 “The Effects of Changes in Foreign Exchange Rates”, as follows: • Assets and liabilities at the closing rate at the date of each consolidated statement of financial position. • Income and expenses, at the average exchange rate for each month. As a result of the translation, the Group has recorded the difference in the caption “Exchange differences on translation of foreign operations” in the consolidated statement of other comprehensive income. Foreign currency balances and transactions: Foreign currency transactions and balances are those performed in currencies different from the functional currency. Transactions in foreign currencies are initially recorded in the functional currency using the exchange rate at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the exchange rate in effect on the reporting date. The differences between the closing rate at the date of each consolidated statement of financial position presented and the exchange rate initially used to record the transactions in foreign currency are recognized in the consolidated statement of income in the period in which they arise, in the caption “Translation result”. Non-monetary
Interest income	(b) Interest income - (b.1) Effective interest rate method - Interest income is recorded using the effective interest rate (“EIR”) method for all financial assets measured at amortized cost, interest rate derivatives for which hedge accounting is applied and the related amortization/recycling effect of hedge accounting. The interest income of financial assets that accrue interests measured at fair value through other comprehensive income according to IFRS 9 is also recorded using the EIR method. Interest expenses are also calculated using the EIR method for all financial liabilities held at amortized cost. EIR is the rate that exactly discounts estimated future cash flows through the expected life of the financial instrument or, when appropriate, a shorter period at the net carrying amount of the financial asset. The EIR is calculated by taking into account transaction costs and any discount or premium on the acquisition of the financial asset, as well as fees and costs that are an integral part of the EIR. The Group recognizes interest income using the best estimate of a constant rate of return over the expected life of the financial asset. Therefore, the EIR calculation also takes into account the effect of potentially different interest rates that may be charged at various stages of the financial asset’s expected life, and other characteristics of the product’s life cycle (including prepayments, penalty interest and charges). If expectations of fixed rate financial assets’ or liabilities’ cash flows are revised for reasons other than credit risk, then changes to future contractual cash flows are discounted at the original EIR, and the adjustment is recorded as a positive or negative adjustment of the carrying amount of the financial asset in the consolidated statement of financial position with an increase or decrease in Interest revenue. For floating-rate financial instruments, periodic re-estimation re-estimating (b.2) Interest income and similar - The Group calculates the interest income by applying the EIR to the gross carrying amount of non-impaired When a financial asset becomes impaired, and, therefore, it is classified as Stage 3 (as established in Note 3.4(h), the Group calculates the interest income by applying the EIR at the amortized cost of the asset. If the financial assets “recover”, as detailed in Note 30.1(d), and is no longer impaired, the Group recalculates the interest income in gross figures. For purchased or originated credit-impaired (POCI) assets, as established in Note 30.1(d), the Group calculates the interest income by determining the credit-adjusted EIR at the amortized cost of the asset. The credit-adjusted EIR is the interest rate that, in the initial recognition, discounts the estimated future cash flows (including credit losses) at the amortized cost of POCI assets. The interest income for all trading assets, that is, for those that are measured at fair value through profit or loss, are presented under the caption “Net gain (loss) of financial assets at fair value through profit or loss” of the consolidated statement of income.
Banking services commissions	(c) Banking services commissions - The Group earns fee and commission income from a diverse range of financial services it provides to its customers. Fee and commission income is recognized at an amount that reflects the consideration to which the Group expects to be entitled in exchange for providing the services. The performance obligations, as well as the timing of their satisfaction, are identified and determined at the inception of the contract. The Group’s income from contracts do not typically include multiple performance obligations. When the Group provides a service to its clients, the consideration is invoiced and generally due immediately upon satisfaction of a service provided at a point in time or at the end of the contract period for a service provided over time. The Group has generally concluded that it is the principal in its revenue arrangements because it typically controls the services before transferring them to the customer. The fees included in the caption “Fees for banking services, net” that make up part of the consolidated statement of income include fee income where performance obligations are satisfied at a specific time or over a period of time. Fee income where performance obligations are satisfied over a period of time include, among others, collection services, funds management, memberships, fees for contingent loans and credit card insurance. Likewise, fee income where performance obligations are satisfied at a specific time include, among others, banking service fees, brokerage and custody services, and credit card fees. Below is the main income from contracts with customers that are recognized in the consolidated statement of financial position: • Fees receivable for credit cards and certain fees receivable for letters of guarantee included in the caption “Other accounts receivable and other assets, net”, represent the Group’s right to an unconditional consideration (i.e., it only requires the passing of time for the consideration payment). This income is measured at amortized cost and is subject to impairment specifications under IFRS 9. • Deferred income from commissions for letters of guarantee included in the caption “Other accounts payable, provisions and other liabilities”, represent the Group’s obligation to render services to a customer, from whom the Group has received a consideration (or a due amount). A liability for unearned fees and commissions is recognized when the payment is made or when the payment is due (whichever happens first). Unearned fees and commissions are recognized as income when the Group renders the service.
Insurance contracts	(d) Insurance contracts – Accounting policies for insurance activities: The Group applies to insurance contracts the existing accounting policies prior to the adoption of IFRS (i.e., accounting standards established by the SBS for financial and insurance entities in Peru) with certain modifications as described below: • Incurred but not reported claims reserves (IBNR): These reserves are calculated and applied at each recording period using the Chain Ladder methodology, which considers past experience based on cumulative claims losses to estimate future claims developments. • Technical reserves for life annuities and retirement, disability and survival pensions: Until May 31, 2018, to calculate the reserve of insurance contracts; the Group considered the Chilean current mortality and morbidity tables (improved RV–2009, B–2006 and MI–2006). In addition, to discount the future cash flows of these liabilities, for portfolio’s debt instruments, the Group set an average rate for matching periods and a 3-percent non-matching SPP-S-2017 SPP-I-2017 No. 886-2018 As previously mentioned, in 2018, the Group’s Management decided to modify its accounting policy and reflect the effect of the change in the value of liabilities coming from retirement, disability and survival pensions, caused by the variations in the market interest rate used to discount these liabilities, in the consolidated statement of other comprehensive income (formerly reflected in the consolidated statement of income). This change was made to reduce the volatility in the profits or losses associated to the effect of changes in market interest rates, as the financial assets supported such insurance liabilities were measured at fair value through other comprehensive income. Likewise, it modified the assumptions used in the determination of the discount rate with the purpose of reflecting the business nature in the long term. The effect of the first application of SPP-S-2017 SPP-I-2017 The effects of the first application of “Matching Adjustement” interest rates as of June 1, 2018, amounted to S/423,080,000; which, according to IAS 8, was prospectively recognized and was part of the year’s movement in other comprehensive results within the caption “Unrealized results, net”, in the year 2018. Product classification: Insurance contracts are those contracts where the Group (the insurer) has accepted significant insurance risk from another party (the policyholder) by agreeing to compensate the policyholder for a specified uncertain future event (the insured event) that adversely affects the policyholder. As a general guideline, the Group determines whether it has significant insurance risk by comparing benefits paid with benefits payable if the insured event did not occur. Insurance contracts may also transfer a financial risk. When the contract has a financial component and transfers no relevant insurance risk as established by IFRS 4 “Insurance Contracts”, the contract is recorded based on IFRS 9 “Financial Instruments”. These contracts are presented in the caption “Other accounts payable, provisions and other liabilities” as “Contract liability with investment component” of the consolidated statement of financial position; see Note 10(a). Once a contract has been classified as an insurance contract, it remains as an insurance contract for the remainder of its life, even if the insurance risk is reduced significantly during this period, unless all rights and obligations are extinguished or expire. Life insurance contracts offered by the Group include retirement, disability and survival insurance, annuities and group and individual life. Non-life Insurance receivables: Insurance receivables are initially recognized when due and are measured at the fair value of the consideration received or receivable. Consequently, in its initial recognition, insurance receivables are measured at amortized cost. As of December 31, 2020 and 2019, the carrying value of the insurance receivables is similar to their fair value due to their short-term maturity. The carrying value of insurance receivables is reviewed for impairment whenever events or circumstances indicate that the carrying amount may not be recoverable, with the impairment loss recorded in the consolidated statement of income. Reinsurance: The Group cedes the insurance risk in the normal course of its operations mainly due to pension fund risks and life insurance risks (individual and group). The reinsurance assets represent balances due and payable by reinsurance companies. Reinsurance is ceded on a proportional basis. The amounts recoverable from the contracts with reinsurers are estimated consistently with the loss reserve pending settlement or losses settled and with the premiums ceded, associated with policies ceded, in accordance with the clauses established in the related reinsurance contracts. Reinsurance assets are reviewed for impairment at each date of the consolidated statement of financial position or more frequently when necessary. Impairment arises when there is objective evidence the Group cannot receive all of the outstanding amounts receivable under the contract terms and the event has a reliably measurable impact on the amounts that the Group will obtain from the reinsurer. Impairment loss is registered in the consolidated statement of income. Reinsurance contracts ceded do not release the Group from its obligations to the insured. The liabilities from reinsurance contracts represent balances due and payable to reinsurance companies. The amounts payable are estimated consistently with the related reinsurance contract. Premiums and claims are presented as gross amounts for the reinsurance ceded. Reinsurance assets or liabilities are written off when the contractual rights are extinguished, expire, or when the contract is transferred to a third party. Reinsurance commissions: The commissions from the reinsurance contracts for premiums ceded are amortized on a straight-line basis over the term of the related insurance contract. Insurance contract liabilities: Life insurance contract liabilities are recognized when contracts are entered into. The technical reserves for retirement, disability and survival insurance and annuities are determined as the sum of the discounted value of expected future pensions to be paid during a defined or non-defined Individual life technical reserves are determined as the sum of the discounted value of expected future benefits, administration expenses, policyholder options and guarantees and investment income, less the discounted value of the expected premiums that would be required to meet the future cash outflows. Furthermore, the technical reserves for group life insurance contracts comprise the provision for unearned premiums and unexpired risks. Insurance claims reserves include reserves for reported claims and an estimate of the IBNR. As of December 31, 2020 and 2019, IBNR reserves were determined on the basis of the Chain Ladder methodology, whereby the weighted average of past claims’ development is projected into the future. Adjustments to the liabilities at each reporting date are recorded in the consolidated statement of income. The liability is derecognized when the contract expires, is discharged or cancelled. At each reporting date an assessment is made on whether the recognized life insurance liabilities are sufficient, by using an existing liability adequacy test as established by IFRS 4. In the case of annuities and retirement, disability and survival insurance, this test was conducted by using current assumptions for mortality and morbidity tables and interest rates. As of December 31, 2020 and 2019, Management determined that liabilities were sufficient and therefore, it has not recorded any additional life insurance contract liability. The accounts payable to reinsurers and coinsurers arise from the ceded premiums issued based on the evaluation of the risk assumed and the losses coming from the reinsurance contracts accepted as well as from the clauses executed for the coinsurance received, and are registered in the item “Accounts payable to reinsurers and coinsurers” that is part of the caption “Other accounts payable, provisions and other liabilities” of the consolidated statement of financial position. Income recognition: Life insurance contracts: Gross premiums on life insurance are recognized as revenue when due from the policyholder. For single premium products, revenue is recognized on the date when the policy is effective. The net premiums earned include the annual variation of technical reserves. Property, casualty and group life insurance contracts: Unearned premiums are those proportions of premiums written in a year that relate to periods of risk afterwards the reporting date. Unearned premiums are calculated on a daily pro rata basis. The proportion attributable to subsequent periods is deferred as a provision for unearned premiums. Recognition of benefits, claims and expenses: (i) Gross benefits and claims Gross benefits and claims for life insurance contracts include the cost of all claims arising during the year, including internal and external claims handling costs that are directly related to the processing and settlement of claims. Death, survival and disability claims are recorded on the basis of notifications received. Annuities payments are recorded when due. (ii) Reinsurance premiums Reinsurance premiums comprise the total premiums payable for the whole coverage provided by contracts entered into in the period and are recognized at the date at which the policy is effective. Unearned ceded premiums are deferred during the period of the related insurance contract. (iii) Reinsurance claims Reinsurance claims are recognized when the related gross insurance claim is recognized according to the terms of the relevant contract. (iv) Acquisition costs Acquisition costs related to the sale of new policies are recognized when incurred.
Financial instruments: Initial recognition	(e) Financial instruments: Initial recognition - (e.1) Date of recognition Financial assets and liabilities, with the exception of loans, are initially recognized at the trading date. This includes regular transactions of purchases or sales of financial assets that require the delivery of assets within the time frame generally established by regulation or convention on the marketplace. Loans are recognized when the funds are transferred to the customers while deposits and obligations are recognized when the funds are received by the Group . (e.2) Initial measurement of financial instruments The classification of financial instruments at initial recognition depends on the characteristics of the business model and contractual flows for managing the instruments, as described in Notes 3.4(f.1.1) and 3.4(f.1.2). Financial instruments are initially measured at their fair value (as defined in Note 3.4(e.4)), except in the case of financial assets and financial liabilities recorded at fair value through profit or loss, transaction costs are added to, or substracted from, this amount. Accounts receivable are measured at the transaction price. When the fair value of financial instruments at initial recognition differs from the transaction price, the Group accounts for the Day 1 profit or loss, as described below. (e.3) Day 1 profit or loss When the transaction price of the instrument differs from the fair value at origination and the fair value is based on a valuation technique that only uses inputs observable in market transactions, the Group recognizes the difference between the transaction price and fair value in the net trading income. In those cases where fair value is based on models for which some of the inputs are not observable, the difference between the transaction price and the fair value is deferred and is only recognized in profit or loss when the inputs become observable, or when the instrument is derecognized. It should be noted that during the years 2020 and 2019, the Group did not originate any differences related to these characteristics. (e.4) Measurement categories of financial assets and liabilities The Group classifies all of its financial assets based on the business model and the contractual terms, measured at either: • Amortized cost, as explained in Note 3.4(f.1). • Fair value through other comprehensive income, as explained in Notes 3.4(f.4) and (f.5). • Fair value through profit or loss, as explained in Note 3.4(f.7). The Group classifies and measures its derivative and trading portfolio at fair value through profit or loss as explained in Notes 3.4(f.2) and (f.3). The Group may designate financial instruments at fair value through profit or loss, if so doing eliminates or significantly reduces measurement or recognition inconsistencies, as explained in Note 3.4(f.7). Financial liabilities, other than financial guarantees, are measured at amortized cost or at fair value through profit or loss when they are held for trading, are derivative instruments or the fair value designation is applied, as explained in Note 3.4(f.6). It should be noted that during 2020 and 2019, the Group only presents derivative financial instruments measured in this way.
Financial assets and liabilities	(f) Financial assets and liabilities - Following is the description of the assets and liabilities held by the Group, as well as the criteria for their classification: (f.1) Assets measured at amortized cost - As required by IFRS 9, the Group measure cash and due from banks inter-bank funds, financial investments in debt instruments, loans and other financial assets at amortized cost if the following two conditions are met: • The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows, and • The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding. The details of these conditions are presented below: (f.1.1) Business model assessment - The Group’s business model is assessed at a higher level of aggregated portfolios, and not instrument by instrument, and is based on observable factors such as: • How the performance of the business model and the financial assets held within that business model are assessed and reported to the entity’s key management personnel. • The risks that affect the performance of the business model (and the financial assets held within that business model) and, in particular, the way those risks are managed. The expected frequency, value and timing of sales are also important aspects of the Group’s assessment. The business model assessment is based on reasonably expected scenarios without taking “worst case” or “stress case”. If cash flows after initial recognition are realized in a way that is different from the Group’s original expectations, the classification of the remaining financial assets that remain in that business model will not be changed, but incorporates such information when assessing newly purchased financial assets. (f.1.2) The SPPI test (Solely payments of principal and interest) - As a second step of its classification process, the Group assesses the contractual terms to identify whether they meet the SPPI test. “Principal”, for the purpose of this test, is defined as the fair value of the financial asset at initial recognition and may change over the life of the financial asset (for example, if there are repayments of principal or amortization of the premium/discount). The most significant elements within a lending arrangement are the time value of money and credit risk. To perform the SPPI assessment, the Group applies judgement and considers relevant factors such as the currency in which the financial asset is denominated, and the period for which the interest rate is set. In contrast, contractual terms that introduce volatility in the contractual cash flows that are unrelated to a basic lending arrangement do not give rise to contractual cash flows that are solely payments of principal and interest on the amount outstanding. In such cases, the financial asset is required to be measured at fair value through profit or loss. (f.2) Derivatives recorded at fair value through profit or loss - A derivative is a financial instrument or other contract with the following three characteristics: • Its value changes in response to the change in a specified interest rate, financial instrument price, commodity price, foreign exchange rate, index of prices or rates, credit rating or credit index, or other variable; provided that, in the case of a non-financial • It requires no initial net investment or an initial net investment that is smaller than the required for other types of contracts expected to have a similar response to changes in market factors. • It is settled at a future date. The Group enters into derivative transactions with various counterparties, such as: interest rate swaps, cross-currency swaps, foreign currency options and foreign currency forward contracts. Derivatives are recorded at fair value and carried as assets when their fair value is positive and as liabilities when their fair value is negative. The notional amount and fair value of such derivatives are presented separately in Note 10(b). Changes in the fair value of derivatives are included in net trading income unless hedge accounting is applied. Hedge accounting disclosures are presented in Note 3.4(i). (f.2.1) Embedded derivatives - An embedded derivative is a component of a hybrid instrument that also includes a non-derivative non-financial independently of that instrument, or has a different counterparty from that instrument, is not an embedded derivative, but a separate financial instrument. Embedded derivatives in financial assets, liabilities and non-financial In the case of embedded derivatives in financial assets, they are not separated from the financial asset and, therefore, the classification rules are applied to the hybrid instrument in its entirety, as described in Note 3.4(e.4). As of December 31, 2020 and 2019, the Group does not present embedded derivatives needed to be separated from the host contract for being closely related. (f.3) Financial assets or financial liabilities held for trading - The Group classifies financial assets or financial liabilities as held for trading when they have been purchased or issued primarily for short-term profit making through trading activities or form part of a portfolio of financial instruments that are managed together, for which there is evidence of a recent pattern of short-term profit taking. Held-for-trading (f.4) Debt instruments at fair value through other comprehensive income - The Group applies the category of debt instruments measured at fair value through other comprehensive income when both of the following conditions are met: • The instrument is held within a business model, the objective of which is achieved by collecting contractual cash flows and selling financial assets. • The contractual terms of the financial asset meet the SPPI test. Debt instruments at fair value through other comprehensive income are subsequently measured at fair value through other comprehensive income. Interest income and foreign exchange gains and losses are recognized in profit or loss in the same manner as for financial assets measured at amortized cost, as explained in Note 3.4(f.1). The expected credit loss calculation for debt instruments at at fair value through other comprehensive income is explained in Note 3.4(h)(iii) . When the Group holds more than one investment in the same security, they are deemed to be disposed of on a “first-in first-out” (f.5) Equity instruments at fair value through other comprehensive income - Upon initial recognition , the Group occasionally elects to classify irrevocably some of its equity investments as equity instruments at at fair value through other comprehensive income when not held for trading. Such classification is determined on an instrument-by- Gains and losses on these equity instruments are never recycled to profit even when the asset is sold. Dividends are recognized in the consolidated statement of income as income when the right of the payment has been established, except when the Group benefits from such proceeds as a recovery of part of the cost of the instrument, in which case, such gains are recorded in other comprehensive income. Equity instruments at at fair value through other comprehensive income are not subject to impairment assessment. (f.6) Financial liabilities - After initial measurement, financial liabilities, except those measured at fair value through profit or loss; see (f.7), are measured at amortized cost. Amortized cost includes commissions and interest, transaction lost and any other premium or discount. A compound financial instrument which contains both a liability and an equity component is separated at the issuance date. The Group first establishes whether the instrument is a compound instrument and classifies such instrument’s components separately as financial liabilities, financial assets, or equity instruments in accordance with IAS 32. Classification of the liability and equity components of a convertible instrument is not revised as a result of a change in the likelihood that a conversion option will be exercised, even when exercising the option may appear to have become economically advantageous to some holders. When allocating the initial carrying amount of a compound financial instrument to the equity and liability components, the equity component is assigned as the residual amount after deducting from the entire fair value of the instrument, the amount separately determined for the liability component. The value of any derivative features (such as call options) embedded in the compound financial instrument, other than the equity component (such as an equity conversion option), is included in the liability component. Once the Group has determined the split between equity and liability, it further assesses whether the liability component has embedded derivatives that must be split for accounting purposes. (f.7) Financial assets and financial liabilities at fair value through profit or loss - Financial assets and financial liabilities in this category are those that are not held for trading and have been either designated by Management upon initial recognition or are mandatorily required to be measured at fair value under IFRS 9. Management designates an instrument at fair value through profit or loss upon initial recognition when one of the following criteria is met: • The designation eliminates, or significantly reduces, the inconsistent treatment that would otherwise arise from measuring the assets or liabilities or recognizing gains or losses on them on a different basis, or • The liabilities are part of a group of financial liabilities which are managed and their performance evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, or • The liabilities contain one or more embedded derivatives, unless they do not significantly modify the cash flows that would otherwise be required by the contract. Financial assets and liabilities at fair value through profit or loss are recorded in the consolidated statement of financial position at fair value. Changes in fair value are recorded in profit and loss with the exception of movements in fair value of liabilities designated at fair value through profit or loss due to changes in the Group’s own credit risk. Such changes in fair value are recorded in other comprehensive income and do not get reclassified to profit or loss. Interest accrued on assets that must be measured at fair value through profit or loss is recorded using the contractual interest rate. Dividend income from equity instruments measured at fair value through profit or loss is recorded in profit or loss as “Interest and similar income”; see Note 19, when the right to the payment has been established. (f.8) Financial guarantees and letters of credit - The Group issues financial guarantees, and letters of credit. Financial guarantees are initially recognized in the consolidated financial statements (within provisions) at fair value, which is equivalent to the commission received. Subsequent to initial recognition, the recognized liability is measured at the higher amount between: a) amount initially recognized less its cumulative amortization; and b) an Expected Credit Loss (“ECL”) provision determined as set out in Note 3.4(h)(ii). The commission received is recognized in the consolidated statement of income in the caption “Fee income from financial services, net” on a straight-line basis over the life of the guarantee. Letters of credit are commitments under which, over the duration of the commitment, the Group is required to provide a loan with pre-specified The nominal contractual value of financial guarantees and letters of credit, where the loan agreed to be provided is on market terms, is not recorded in the consolidated statement of financial position. The nominal values of these instruments together with the corresponding ECLs are disclosed in Note 6(d). (f.9) Reclassification of financial assets and liabilities - The reclassification of financial assets will take place as long as the business model that manages the financial assets is changed. It is expected that this change is very rare. These changes are determined by Management as a result of external or internal changes and must be significant for the Group’s operations and demonstrable to third parties. Consequently, a change in the Group’s business model will take place only when it begins or ceases to carry out an activity that is significant for its operations. As of December 31, 2020 and 2019, the Group has not reclassified its financial assets after their initial recognition. Financial liabilities are never reclassified. (f.10) Repurchase agreements - Securities sold under repurchase agreements on a specified future date are not derecognized from the consolidated statement of financial position since the Group retains substantially all of the risks and rewards inherent to its ownership. Cash received is recognized as an asset with the corresponding obligation to return it, including accrued interest, as a liability, reflecting the transaction’s economic substance as a loan to the Group. The difference between the sale and repurchase price is recorded as interest expense and is accrued over the life of the agreement using the effective interest rate and is recognized in the caption “Interest and similar expenses” of the consolidated statement of income. As of December 31, 2020 and 2019, the Group did not keep any repurchase agreements.
Derecognition of financial assets and liabilities	(g) Derecognition of financial assets and liabilities - (g.1) Derecognition due to substantial change in terms and conditions - The Group derecognizes a financial asset, such as a loan to a customer, when the terms and conditions have been renegotiated to the extent that, substantially, it becomes a new loan, with the difference recognized as a derecognition gain or loss, to the extent that an impairment loss has not already been recorded. When assessing whether or not to derecognize a loan to a customer, among others, the Group considers the following factors: • Change in the loan’s currency. • Introduction of an equity feature. • Change in customer’s credit risk. • If the modification is such that the instrument would no longer meet the SPPI criterion. Regarding the financial liabilities, the Group considers a substantial amendment based on qualitative factors and provided it exists a difference between the present value of the discounted cash flows under the new conditions and the original book value of the financial liability is larger than ten percent. If the modification does not result in cash flows that are substantially different, the modification does not result in derecognition. Based on the change in cash flows discounted at the original EIR, the Group records a modification gain or loss, to the extent that an impairment loss has not already been recorded. (g.2) Derecognition other than for substantial modification - (g.2.1) Financial assets A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when the rights to receive cash flows from the financial asset have expired. The Group has transferred the financial asset if, and only if, either: • Has transferred its contractual rights to receive cash flows from the financial asset, or • It retains the rights to the cash flows, but has assumed an obligation to pay the received cash flows in full without material delay to a third party under a “pass-through” arrangement. Pass-through arrangements are transactions whereby the Group retains the contractual rights to receive the cash flows of a financial asset (the ‘original asset’), but assumes a contractual obligation to pay those cash flows to one or more entities (the ‘eventual recipients’), when all of the following conditions are met: • The Group has no obligation to pay amounts to the eventual recipients unless it has collected equivalent amounts from the original asset. • The Group cannot sell or pledge the original asset other than as security to the eventual recipients. • The Group has to remit any cash flows it collects on behalf of the eventual recipients without material delay. In addition, the Group is not entitled to reinvest such cash flows, except for investments in cash or cash equivalents including interest earned, during the period between the collection date and the date of agreed revision with the eventual recipients. A transfer only qualifies for derecognition if either: • The Group has transferred substantially all the risks and rewards of the asset, or • The Group has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset. The Group considers that control is transferred if, and only if, the transferee has the ability to sell the asset in its entirety to an unrelated third party and is able to exercise that ability unilaterally. When the Group has neither transferred nor retained substantially all the risks and rewards and has retained control of the asset, the asset continues to be recognized only to the extent of the Group’s continuing involvement, in which case, the Group also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group retains. When the continuing involvement takes the form of a guarantee over the transferred asset, the amount of the Group’s continuing involvement will be the lowest between the asset amount and the maximum amount of consideration the Group may be required to pay. When the continuing involvement takes the form of a written or purchased option (or both) over the transferred asset, the amount of the Group’s continuing involvement will be the amount of the transferred asset that the Group could repurchase. In the case of a written put option on an asset that is measured at fair value, the amount of the Group’s continuing involvement will be limited to the lowest between the fair value of the transferred asset and the option exercising price. The net loss originated as consequence of the derecognition of financial asset accounts measured at amortized cost is calculated as the difference between the book value (impairment included) and the amount received. As of December 31, 2020 and 2019, the Group did not recognize net losses as a consequence of derecognition of financial assets accounts. (g.2.2) Financial liabilities A financial liability is derecognized when the obligation under the liability has been discharged, cancelled or has expired. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such exchange or modification is treated as a derecognition of the original liability and the recognition of a new liability. The difference between the carrying value of the original financial liability and the consideration paid is recognized in profit or loss of the period.
Impairment of financial assets	(h) Impairment of financial assets - (i) Overview of the expected credit loss principles - The Group records an allowance for expected credit losses for all loans and other debt financial assets not held at fair value through profit or loss, together with financial guarantee contracts. Equity instruments are not subject to impairment under IFRS 9. The determination of the expected credit loss is based on the credit losses expected to arise over the life of the asset, unless there has been no significant increase in credit risk since origination, in which case, the allowance is based on the 12-month Both lifetime expected credit loss and 12-month The Group has established a policy to perform an assessment, at the end of each reporting period, of whether a financial instrument’s credit risk has increased significantly since initial recognition. This is further explained in Note 30.1(d). Based on the above mentioned process, IFS groups its loans into “Stage 1”, “Stage 2”, “Stage 3” and purchased or originated credit impaired financial assets (“POCI”), as described below: Stage 1: When loans are first recognized, the Group recognizes an allowance based on the 12-month Stage 2: When a loan has shown a significant increase in credit risk since inception, the Group records an allowance based on the expected credit lossfor rhe entire lifetime of the financial asset. Stage 2 also includes loans whose credit risk has improved and the loan has been reclassified from Stage 3. Stage 3: Loans considered credit impaired (as outlined in Note 30.1(d)). The Group records an allowance for the entire lifetime of the financial asset. POCI: Purchased or originated credit impaired assets are financial assets that are impaired on initial recognition. POCI assets are recorded at fair value at original recognition and interest income is subsequently recognized based on a credit-adjusted EIR. ECLs are only recognized or released to the extent that there is a subsequent change in the expected credit losses. It should be noted that during the year 2020 and 2019, the Group has not purchased or originated POCI financial assets. For financial assets for which the Group has no reasonable expectations of recovering either the entire outstanding amount, or a proportion thereof, the gross carrying amount of the financial asset is reduced. This is considered a (partial) derecognition of the financial asset. The Group recognizes a value correction for expected credit losses on the following financial assets: • Financial assets that are measured at amortized cost. • Financial assets that are measured at fair value with changes in other comprehensive income if the following two conditions are met: (i) The financial asset is maintained within a business model whose objective is achieved by obtaining contractual cash flows and selling financial assets; and (ii) The contractual terms of the financial asset give rise, on specified dates, to cash flows that are only payments of the principal and interest on the outstanding principal amount. • Accounts receivable from leases. • Assets from contracts. • Financial guarantee contracts. In this regard, as of December 31, 2020 and 2019, the Group’s financial assets subject to a correction for expected credit loss are the following: • Cash and due from banks. • Inter-bank funds. • Financial investments; see Notes 3.4(f), 5 and 30.1(e). • Loans; see Notes 3.4(f.1), 6 and 30.1(d). • Due from customers on acceptances. • Other accounts receivable and other assets. Due to the Covid-19 (ii) Calculation of ECL - The Group calculates ECL based on three probability-weighted scenarios to measure the expected cash shortfalls, discounted at an approximation to the EIR. A cash shortfall is the difference between the cash flows that are due to an entity in accordance with the contract and the cash flows that the entity expects to receive. The mechanics of the ECL calculations are described below, and the key elements are the following: • PD (“Probability of default”) is an estimate of the likelihood of default over a given time horizon. A default may only happen at a certain time over the assessed period, if the financial asset has not been previously derecognized and is still in the portfolio. The definition of PD is further explained in Note 30.1(d). • EAD (“Exposure at default”) is an estimate of the exposure at a future default date, taking into account expected changes in the exposure after the reporting date, including repayments of principal and interest, whether scheduled by contract or otherwise, expected drawdowns on committed facilities, and accrued interest from missed payments. The definition of EAD is further explained in Note 30.1(d). • LGD (“Loss Given Default”) is an estimate of the loss arising in the case where a default occurs at a given time. It is based on the difference between the contractual cash flows due and those that the lender would expect to receive, including from the realization of any collateral. It is usually expressed as a percentage of the EAD. The definition of LGD is further explained in Note 30.1(d). When estimating the ECLs, the Group considers three scenarios (optimistic, base and pessimistic). Each of these is associated with different PDs, as presented in Note 30.1(d). When is relevant, the assessment of multiple scenarios also incorporates how defaulted loans are expected to be recovered, including the probability that the loans will “cure” and the value of collateral or the amount that might be received for selling the asset. With the exception of credit cards, for which the treatment is separately set out in (iv) below, the maximum period for which the credit losses are determined is the contractual life of a financial instrument (considering the prepayments) unless the Group has the legal right to call it earlier. Impairment losses and reversals are accounted for and disclosed separately from modification losses or gains that are accounted for as an adjustment of the financial asset’s gross carrying value. The criteria followed for calculating the ECL based on each stage are described below: • Stage 1: The provision for credit losses of those financial instruments that do not show a significant increase in risk since the initial recognition, will be calculated as the expected credit losses in the following 12 months. The group calculates the expectation that there is a probability of default (PD) in the 12 months after the reporting date. To this probability of default is multiplied and expected loss in case of default (LGD) and exposure on the date of default (EAD) and discounting the original effective interest rate. This calculation is made for each of the three scenarios (optimistic, base and pessimistic) defined by the Group. • Stage 2: When the financial instrument shows a significant increase in credit risk since initial recognition, the provision of credit losses of this financial instrument will be calculated as the expected credit loss throughout the life of this asset. The calculation method is similar to that for Stage 1, including the use of multiple scenarios, but expected credit loss is estimated over the lifetime of the instrument. • Stage 3: When there is objective evidence that the financial instrument is impaired, the provision of credit losses will be calculated as the expected credi tloss over the life of the asset. The method is similar to that for Stage 2, with the PD set at 100 percent. Financial guarantee contracts The Group measures each financial guarantee as the highest of the amount initially recognized minus cumulative amortization recognized in the consolidated statement of income, and the ECL provision. For this purpose, the Group estimates ECL based on the present value of the expected payments to reimburse the holder for a credit loss that it incurs. The deficits are discounted by the risk-adjusted interest rate relevant to the exposure. The ECLs related to financial guarantee contracts are recognized in provisions. (iii) Debt instruments measured at fair value through other comprehensive income - The ECLs for debt instruments measured at fair value through other comprehensive income do not reduce the carrying amount of these financial assets in the consolidated statement of financial position, which remains at fair value. However, the expected losses that arise at each measurement date must be reclassified from other comprehensive income to results of the period. (iv) Credit cards - The Group calculates the expected losses in a period that reflects the Group’s expectations regarding the client’s behavior, probability of default and the Group’s future risk mitigation procedures that could include the reduction or cancellation of lines of credit. Based on past experience and the Group’s expectations, the period during which the Group calculates the expected lifetime losses of this product is 17 months. The assessment of whether there has been a significant increase in credit risk for revolving products is similar to other credit products. This is based on changes in the customer’s credit rating, as explained in Note 30.1(d). The interest rate used to discount the ECL for credit cards is based on the average effective interest rate that is expected to be charged over the expected period of exposure to the facilities. This estimation takes into account that many facilities are repaid in full each month and are consequently not charged interest. (v) Forward-looking information - In its expected credit loss models, the Group relies on the following macroeconomic variables as forward-looking information inputs as of December 31, 2020 and 2019: 2020 2019 GDP growth X X Unemployment rate X X Consumer price index X Consumer X Inflation X Domestic demand X X Exchange rate X Purchase capacity X X Real compensation X X Unit labor cost X The inputs and models used, see Note 30.1, for calculating ECLs may not always capture all characteristics of the market at the date of the consolidated financial statements. To reflect this, qualitative adjustments or overlays are occasionally made as temporary adjustments when such differences are significantly material. Detailed information about these inputs are provided in Note 30.1(d). (vi) Valuation of guarantees - To mitigate the credit risks on financial assets, the Group generally uses three types of guarantees: physical guarantee, personal guarantees and title guarantees. The guarantee, unless recovered, is not recorded in the Group’s consolidated statement of financial position. However, the fair value of the guarantee affects the calculation of the expected losses, and because of that, it is assessed periodically. The nominal contract value of the guarantees and the letters of credit not used where the loan was agreed to be granted is in market terms, is not recorded in the consolidated statement of financial position. The nominal values of these instruments together with the corresponding expected losses are disclosed in Note 30.1(d). To the extent possible, the Group uses active market data for valuing financial assets held as guarantees. Non-financial (vii) Write-offs - Financial assets are written off only when the Group has stopped pursuing the recovery, at which time the cumulative provision recorded coincides with the total amount of the asset. (viii) Refinanced and modified loans - The Group may make concessions or modifications to the original terms of loans as a response to the borrower’s financial difficulties, rather than taking possession or to otherwise enforce collection of guarantees. Once the terms have been renegotiated, any impairment is measured using the original EIR (as calculated before the modification of terms). It is the Group’s policy to monitor refinanced loans to help ensure that future payments continue to be likely to occur. A refinanced asset is initially classified into Stage 2 and there will be no clean-up During 2020 and due to the Covid-19 Covid-19
Hedge derivatives	(i) Hedge derivatives - Derivatives are initially recognized at fair value at the date a derivative contract is entered into and are subsequently remeasured at their fair value. All derivatives are recognized as assets when the fair value is positive and they are recorded as “Accounts receivables related to derivative financial instruments” under “Other accounts receivable and other assets, net” and as liabilities when they are negative and they are recorded as “Accounts payable related to derivative financial instruments” under “Other accounts payable, provisions and other liabilities” in the consolidated statement of financial position. Derivatives can be designated as hedging instruments under hedge accounting and in the event they qualify, depending upon the nature of the hedged item, the method for recognizing gains or losses from changes in fair value will be different. These derivatives, which are used to hedge exposures to risk or modify the characteristics of financial assets and liabilities and that meet IFRS 9 criteria, are recognized as hedging accounting. Derivatives not designated as hedging instruments or that do not qualify for hedging accounting are initially recognized at fair value and are subsequently remeasured at their fair value, which is estimated based on the market exchange rate and interest rate. Gains or losses due to changes in their fair value are recorded in the consolidated statement of income, see Note 3.4(f.2). In accordance with IFRS 9, to qualify for hedge accounting, all of the following conditions must be met: (i) The hedging relationship consists of only hedging instruments and eligible hedged items. (ii) At the inception of the hedge, there is formal designation and documentation of the hedging relationship and the entity’s risk management objective and strategy for undertaking the hedge. This documentation will include the identification of the hedging instrument, the hedged item, the nature of the risk being hedged, and the way the entity will assess if the hedging relationship meets the hedge effectiveness requirements. (iii) The hedging relationship meets all the following hedge effectiveness requirements: • There is an economic relationship between the hedged item and the hedging instrument. • The effect of the credit risk does not dominate the value changes that result from that economic relationship. • The hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the entity actually hedges and the quantity of the hedging instrument that the entity actually uses to hedge that quantity of the hedged item. IFRS 9 presents three hedge accounting categories: fair value hedge, cash flow hedge, and hedge of net investments in a foreign operation. The Group uses derivatives as hedging instruments under cash flow hedges, as detailed in Note 10(b). For derivatives that are designated and qualify as cash flow hedge, the effective portion of derivative gains or losses is recognized in other comprehensive income for cash flow hedge, and reclassified to income in the same period or periods in which the hedge transaction affects income. The portion of gain or loss on derivatives that represents the ineffective portion or the hedge components excluded from the assessment of effectiveness is recognized immediately in income. Amounts originally recorded in other comprehensive income and subsequently reclassified to income are recorded in the corresponding income or expenses lines in which the related hedged item is reported. When a hedging instrument expires, is sold, when a hedge no longer meets the criteria for hedge accounting or when the Group re-designates
Leases	(j) Leases - The determination of whether an arrangement is a lease, or contains a lease, is based on the substance of the arrangement at contract inception: whether the fulfilment of the arrangement is dependent on the use of a specific asset or assets or whether the arrangement conveys a right to use the asset., even if it is not explicitly specified in the contract in exchange for consideration. (i) The Group as a lessee - The Group, as a lessee, applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value • Right-of-use The Group recognizes right-of-use Right-of-use right-of-use right-of-use • Lease liabilities - The Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. Given that this interest rate implicit in the lease agreement is not easily determinable, in the calculation of the present value of the lease payments, the Group uses the rate it applies to its loans. The lease payments include fixed payments (less any lease incentives receivable), variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating the lease, if the lease term reflects exercising the option to terminate. Variable lease payments that do not depend on an index or a rate are recognized as expenses in the period in which the event or condition that triggers the payment occurs. Lease liabilities are presented in Note 10 as “Lease liabilities” in the caption “Other accounts payable, provisions and other liabilities”. The Group performs accounting estimates related to the determination of terms and rates of the lease agreements, as detailed below: • Determination of the lease term for lease contracts with renewal and termination options The Group as a lessee determines the lease term as the non-cancellable • Estimating the incremental borrowing rate In order to determine the interest rate implicit in the lease, the Group uses its incremental borrowing rate - “IBR” to measure lease liabilities. The IBR is the rate of interest that the Group would have to pay to borrow over a similar term, and with a similar security, the funds necessary to obtain an asset of a similar value to the right-of-use The Group used the exemption proposed by the standard for short term and low value assets; thus, short term and low value lease agreements are kept classified as operating leases, and the disbursements incurred due to these leases are recorded in the caption “Administrative expenses” of the consolidated statement of income. Until December 31, 2018, leases in which a significant portion of the asset’s risks and benefits was retained by the lessor were classified as operating leasing according to IAS 17 “Leases”. Under this concept, the Group held mainly rented facilities used as offices and agencies of the Group’s Subsidiaries; see Note 25(c). (ii) The Group as a lessor – As of December 31, 2020 and 2019, the Group holds the following types of leases: • Financial leases – Leases in which the Group substantially transfers all risks and benefits related to the ownership of the asset are classified as financial leases. Financial leases are recognized as loans at the present value of the installments. The difference between the total value receivable and the present value of the loan is recognized as accrued interest. This income is recognized during the term of the lease using the effective interest rate method, which reflects a constant rate of return. As of December 31, 2020 and 2019, leasing receivables are subject to the financial asset impairment policy; see Notes 3.4(f.1) and (h). • Operating leases – Leases in which the Group does not substantially transfers all risks and benefits related to the ownership of the asset are classified as operating leases. Lease revenues obtained from investment properties are recorded using the straight-line method for the contract terms, and they are recorded as a revenue in the consolidated statement of income due to their operative nature, except for contingent lease revenues, which are recorded when realized. The lease term is the non-cancelable Amounts received from tenants to terminate leases or to compensate impairment of leased facilities are recognized as revenues in the consolidated statement of income when the right to receive them arises. Service charges, administration expenses and other recoverable expenses paid by the lessees and the revenues resulting from expenses charged to the lessees are recognized in the period in which the compensation becomes an account receivable. Service charges and administration expenses and other receipts are included in the gross revenues from rentals of the related costs, given that Management considers that the Group acts as principal party.
Customer Loyalty Program	(k) Customer Loyalty Program - The Group has a customer loyalty program, which allows customers to accumulate points that can be exchanged for products. Loyalty points give rise to a separate performance obligation, since they provide a material right to the customer. A part of the transaction price is allocated to the loyalty points granted to customers on the basis of the relative independent selling price and is recognized as a contractual liability until the points are redeemed and presented as “Other accounts payable” in the item “Other accounts payable, provisions and other liabilities” of the consolidated statement of financial position. Expenses are provisioned montlhy regardless of the customer’s redemption of products. By estimating the selling price independent of the loyalty points, the Group considers the probability of a client will use the cumulated points. The Group updates the estimates of points to be monthly redeemed and any adjustment to the liability balance will be recognized in the caption “Administrative expenses” of the consolidated statement of income.
Services of purchase-sale of financial investments "principal versus agent"	(l) Services of purchase-sale of financial investments “principal versus agent”- The Group has contracts with customers to buy and sell, on their behalf, financial investments in the stock market and over-the-counter When another party participates in the supply of services to their client, the Group determines whether it is a principal or an agent in these transactions when evaluating the nature of its agreement with the client. The Group is a principal and records the revenue by gross amounts if it controls the committed services before transferring to the customer. However, if the Group’s role is only to arrange for another entity to provide the services, then the Group is an agent and records the revenues for the net amount it retains for its services as an agent.
Investments in associates	(m) Investments in associates - An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the entity, but without having control over those policies. The considerations taken for determining significant influence are similar to those needed to determine control over Subsidiaries. The Group’s investments in its associates are recognized initially at cost and then are accounted for using the equity method. The Group’s investments in associates are included in the caption “Other accounts receivable and other assets, net” of the consolidated statement of financial position, see note 10. Gains resulting from the use of the equity method of accounting are included in the caption “Other income” of the consolidated statement of income.
Investment property	(n) Investment property - Investment property comprises land and buildings (mainly shopping malls, educational institutions and offices) that are not occupied substantially for use in the operations of the Group, nor for sale in the ordinary course of business, but are held primarily to earn rental income and capital appreciation. These buildings are substantially rented and not intended to be sold in the ordinary course of business. Investment property comprises completed property and property under construction or re-development. The Group measures its investment property at fair value according to the requirements of IAS 40 “Investment Property”, as it has chosen to use the fair value model as its accounting policy. Investment property is measured initially at cost, including transaction costs, that include transfer taxes, professional fees for legal services and initial leasing commissions to bring the property to the condition necessary to start operating. The carrying amount also includes the cost of replacing part of an existing investment property at the time that cost is incurred if the recognition criteria are met. Properties under construction are measured based on estimates prepared by independent real estate valuation experts, except where such values (e.g. work-in-progress work-in-progress Subsequent to initial recognition, investment property is recorded at fair value. Gains or losses arising from changes in fair values are included in the caption “Net gain on investment property” of the consolidated statement of income in the year in which they arise. Fair values are assessed periodically by Management, based on the discounted cash flows that are expected to be obtained from these investments. Fair values of investment properties under construction or investment properties held to operate in the future are assessed by an independent external appraiser, through the application of a recognized valuation model. See Note 7 for details of fair value and related assumptions. Transfers to or from Investment property are made only when there is a change in the use of the asset. In case of assets transferred from Investment property to Property, furniture and equipment, the reclassified amount corresponds to the asset’s fair value at the date when the asset’s use was changed. If an item of Property, furniture and equipment moves to Investment property, the Group transfers the fixed asset’s net cost to Investment property and the asset is subsequently measured at fair value according to the policies established by the Group. During 2020, and considering the new rented properties, the Group transferred part of the “Orquídeas” building, located in San Isidro, Lima, from “Property, furniture and equipment” to “Investment property”, for S/5,201,000. Likewise, during 2018, the Group transferred “Las Orquídeas” building, located in San Isidro, Lima, from “Investment property” to “Property, furniture and equipment” for S/20,029,000. In addition, the Group transferred part of the “Pardo y Aliaga” building and part of the “Sede Wiese”, both located in San Isidro, Lima, from “Property, furniture and equipment” to “Investment property” for S/6,453,000 and S/4,037,000, respectively. Investment property is derecognized when it has been disposed or withdrawn from use and no future economic benefit is expected from its disposal. The difference between the net disposal proceeds and the carrying amount of the asset would result in either gains or losses at the retirement or disposal of investment property. Any gains or losses are recognized in the consolidated statement of income of the year of retirement or disposal.
Property, furniture and equipment	(o) Property, furniture and equipment, net - Property, furniture and equipment are stated at historical acquisition cost less residual value, cumulative depreciation and impairment losses, if applicable. The historical acquisition cost includes the expenses that are directly attributable to the acquired property, furniture or equipment. Maintenance and repair costs are charged to the consolidated statement of income; significant renewals and improvements are capitalized when it is probable that future economic benefits, in excess of the originally assessed standard of performance, will result from the use of the acquired property, furniture or equipment. Land does not depreciate. Depreciation of property, furniture and equipment is calculated using the straight-line method over the estimated useful lives, which are as follows: Years Buildings and facilities 40 - 75 Leasehold improvements 5 Furniture and equipment 10 Vehicles 5 An item of property, furniture and equipment and any significant part initially recognized, is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising from the derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the consolidated statement of income. The residual value of each asset, its useful life and the selected depreciation method are periodically reviewed to ensure that they are consistent with current economic benefits and useful life expectations.
Assets seized through legal actions	(p) Assets seized through legal actions - Assets seized through legal actions are recorded in the item “Others” of the caption “Other accounts receivable and other assets, net” of the consolidated statement of financial position, see note 10; and are recognized at the lower value between the cost or the estimated market value (minus cost to sell), determined from valuations made by independent appraisers. Reductions in book value are recorded in the consolidated statement of income.
Intangible assets with finite useful lives	(q) Intangible assets with finite useful lives - Generally, the intangible assets with finite useful lives are included in the caption “Intangibles and goodwill, net” of the consolidated statement of financial position and they are mainly costs incurred in connection with the acquisition of computer software used in operations and other minor intangible assets. The amortization expense is calculated following the straight-line method over the useful life estimated between 4 and 5 years; see Note 9. On the other hand, when an insurance contract portfolio is acquired, whether directly from another insurance company or as part of a business combination (in the case of the Group, the acquisition of Seguros Sura), the difference between the fair value of the insurance contract liability and the value of the insurance contract liability, as measured with the acquirer’s accounting policies, is recognized as an intangible asset named “Present Value of In-Force In this sense, PVIFs resulting from the acquisition of Seguros Sura are recognized in the consolidated statement of financial position at their estimated market value at the acquisition date. After the initial recognition, the PVIF is recorded at cost, minus the cumulative amortization and cumulative impairment loss, if any. The PVIF is amortized on a linear basis over the useful life of the acquired policies, which has been estimated in ten years. The recoverability of PVIF is considered as part of the liability adequacy test performed at each reporting period. PVIF is derecognized when the related contracts are settled or disposed of. Changes in the estimated useful life or in the pattern of consumption of the expected future economic benefits embedded in the intangible asset (PVIF) are recorded by changing the amortization period or method and are treated as a change in an accounting estimate. Gains or losses arising from the derecognition of an intangible asset are measured as the difference between the net amount of the disposal of the asset and the book value of said asset and they are recognized in the consolidated statement of income at the derecognition date.
Goodwill	(r) Goodwill - Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling re-assesses After initial recognition, goodwill is measured at cost less any cumulative impairment loss, if any. A goodwill impairment testing is performed on a yearly basis. To perform an impairment testing, goodwill acquired in a business combination is allocated, since the acquisition date, to one of the Group’s cash-generating units (henceforth “CGU”) that are expected to benefit from the business combination, irrespective of whether other assets or liabilities of the acquirer are assigned to those units. Goodwill impairment is determined by assessing the recoverable amount of each CGU (or group of CGUs) to which the goodwill relates. When the recoverable amount of the CGU is less than its carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods. Where the goodwill has been allocated to the CGU and part of the operation within that unit is disposed of, the goodwill associated to the disposed operation is included in the carrying amount of the operation when determining the gain or loss of disposal. Goodwill disposed in these circumstances is measured based on the relative values of the disposed operation and the withheld portion of the CGU retained. Goodwill, recorded by the Group; see Note 9(b), arises from the acquisition of Seguros Sura and, considering that this entity was merged with Interseguro, has been allocated to the CGU of the insurance business.
Business combinations	(s) Business combinations - Business combinations are accounted for using the acquisition method established by IFRS 3 “Business Combinations”. The cost of an acquisition is measured as the aggregate of the consideration transferred, which is measured at the acquisition date’s fair value, and the amount of any non-controlling non-controlling The Group determines that it has acquired a business when the the acquired set of activities and assets include an input and a substantive process that together significantly contribute to the ability to create outputs . The acquired process is considered substantive if it is critical for the capacity to the ability to continue producing outputs , and the inputs acquired include an organized workforce with the necessary skills, knowledge or experience to performe that process or it significantly contributes to the ability to continue producing outputs and is considered unique or scarce or cannot be replaced without incurring in significant costs, effort or delay in the ability of continue producing outputs. When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiree. Any contingent consideration to be transferred by the acquirer shall be recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IFRS 9 “Financial Instruments: Recognition and Measurement”, is measured at fair value with the changes in the consolidated statement of income or in the consolidated statement of other comprehensive income. If the contingent consideration is not within the scope of IFRS 9, this shall be measured according to the applicable IFRS. The contingent consideration that is classified as equity must not be measured again and its subsequent settlement shall be recorded in equity. As of December 31, 2020 and 2019, there have been no contingencies arising from business combinations. A business combination between entities or businesses under common control is beyond the scope of IFRS 3, because it corresponds to a business combination in which all entities or businesses that are combined are ultimately controlled by the same part or parts, both before and after the business combination. In these transactions, the Group recognizes the assets acquired under the method of unification of interest, whereby the assets and liabilities of the combined companies are reflected in their book values and no commercial credit is recognized as a result of the combination.
Impairment of non-financial assets	(t) Impairment of non-financial Property, furniture and equipment and intangible assets with a finite life are assessed to determine whether there are any indications of impairment as of the closing of each period. If any indication exists, the Group estimates the asset’s recoverable value. The recoverable amount of the assets is the highest between the value of an asset or a CGU less the costs of sale and its use value, and it is determined for an individual asset, unless the asset does not generate cash revenues that are largely independent from those of other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax
Due from customers on acceptances	(u) Due from customers on acceptances - Due from customers on acceptances corresponds to accounts receivable from customers for import and export transactions, whose obligations have been accepted by the Group. The obligations that must be assumed by the Group for such transactions are recorded as liabilities.
Defined contribution pension plan	(v) Defined contribution pension plan - The Group only operates a defined contribution pension plan. The defined contribution payable in the pension plan is in proportion to the services rendered to the Group by the employees and it is recorded as an expense in the caption “Salaries and employee benefits” of the consolidated statement of income. Unpaid contributions are recorded as liabilities.
Provisions	(w) Provisions - Provisions are recognized when the Group has a present obligation (legal or implicit) as a result of a past event, and it is probable that an outflow of resources embodying economic benefits will be required in order to settle the obligation and a reliable estimate can be made of the amount of the obligation. The expense relating to any provision is presented in the consolidated statement of income, net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a pre-tax
Contingencies	(x) Contingencies - Contingent liabilities are not recognized in the consolidated financial statements, but are disclosed in notes to the consolidated financial statements, unless the probability of an outflow of resources is remote. Contingent assets are not recorded in the consolidated financial statements, but they are disclosed if it is probable that an inflow of economic benefits will emerge.
Fair value measurement	(y) Fair value measurement - Fair value is the price that would be received for the sale of an asset or paid for the transfer of a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either: • On the principal market for the asset or liability; or • In the absence of a principal market, on the most advantageous market for the asset or liability. The principal or the most advantageous market must be accessible by the Group. Also, the fair value of a liability reflects its non-performance The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest. When possible, the Group measures the fair value of a financial instrument using the quoted price in an active market for that instrument. A market is regarded as active if transactions for the asset or liability take place with sufficient frequency and volume to provide pricing information on an ongoing basis. If there is no quoted price on an active market, then the Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure the fair value, maximizing the use of relevant and observable data and variables, and minimizing the use of unobservable data and variables. The chosen valuation technique incorporates all of the factors that market participants would take into account in pricing a transaction. In the case of investment property, the Group has considered the specific requirements relating to highest and best use, valuation of premises and principal (or most advantageous) market. The determination of investment property fair value requires the use of estimations such as the future cash flows of the assets (e.g., leases, sales, fixed rents for the different lessees, variable rents based on the sales percentage, operating costs, construction costs, maintenance costs, and the use of discount rates). Additionally, real estate development risks (such as construction and abandonment) are also taken into account when determining the fair value of the land related to the investment property under construction. The fair value of investment property in the consolidated statement of financial position must reflect the volatile nature of real estate markets; therefore, Management and its appraisers use their market knowledge and professional criteria and do not depend solely on historical comparable transactions. In this sense, there is a higher degree of uncertainty than when a more active market exists for the estimation of fair value. Significant methods and assumptions used in the estimation of fair value of investment property are detailed in Note 7. All assets and liabilities for which the fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy described below: • Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities. • Level 2 - Valuation techniques for input that is significant to the fair value measurement is directly or indirectly observable. • Level 3 - Valuation techniques for which data and variables of the lowest significant level to measure fair value are unobservable. For assets and liabilities that are recognized at fair value in the consolidated financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by re-assessing For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of hierarchy of the fair value, as explained above. Fair values of financial instruments measured at amortized cost are disclosed in Note 31(b).
Income Tax	(z) Income Tax - Income Tax is computed based on the separate financial statement of each Subsidiary. Deferred Income Tax is accounted for in accordance with IAS 12 “Income Taxes”. In this sense, the deferred Income Tax reflects the effects of temporary differences between the carrying amounts of assets and liabilities for accounting purposes and the amounts determined for tax purposes. Deferred assets and liabilities are measured using the tax rates that are expected to be in force in the years in which such temporary differences are expected to be recovered or settled. Consequently, the deferred Income Tax has been calculated by applying the rates that are in force; see Note 17(c). The measurement of deferred tax assets and deferred tax liabilities reflects the tax consequences that arise from the manner in which each individual entity of the Group expects, at the consolidated statement of financial position dates, to recover or settle the carrying amount of their assets and liabilities. Deferred tax assets and liabilities are recognized regardless of when the temporary differences are likely to reverse. Deferred tax assets are recognized when it is probable that sufficient taxable income will be generated against which the deferred tax assets can be offset. At each consolidated statement of financial position date, unrecognized deferred assets and the carrying amount of deferred tax assets registered are assessed. A previously unrecognized deferred tax asset is recognized to the extent that it has now become probable that future taxable income will allow the deferred tax asset to be recovered. Likewise, the carrying amount of a deferred tax asset is reduced when it is no longer probable the generation of a sufficient taxable income that allow the application of the tax deferred asset. According to IAS 12, the deferred Income Tax is determined by applying the Income Tax rate applicable to the retained earnings, recognizing any additional tax on distribution of dividends that may arise on the date when the liability is recognized.
Segment information	(aa) Segment information - IFRS 8 “Operating Segments” requires that the information of operating segments be disclosed consistently with information provided by the chief operating decision maker, who allocates resources to the segments and assesses their performance. Segment information is presented in Note 28.
Fiduciary activities and management of funds	(ab) Fiduciary activities and management of funds - The Group provides trust management, investment management, advisory and custody services to third parties that result in the holding of assets on their behalf. These assets and the income arising thereon are excluded from these consolidated financial statements, as they are not assets of the Group; see Note 32. Commissions generated from these activities are included in the caption “Fee income from financial services, net” of the consolidated statement of income.
Earnings per share	(ac) Earnings per share - The amount of basic earnings per share is calculated by dividing the net profit for the year attributable to common shareholders by the weighted average number of common shares outstanding during the year. As of December 31, 2020 and 2019, the Group does not have financial instruments with dilutive effect, therefore, basic and diluted earnings per share are identical for the years reported.
Capital surplus	(ad) Capital surplus - It is the difference between the nominal value of shares issued and their public offering price made in 2007 and 2019; see Note 1(c). Capital surplus is presented net of expenses incurred in the issuance of shares.
Treasury stock	(ae) Treasury stock - Shares repurchased are recorded in the shareholders’ equity under treasury stock caption at their purchase price. No loss or gain is recorded in the consolidated statement of income arising from the purchase, sale, issuance or amortization of these instruments. Shares that are subsequently sold are recorded as a reduction in treasury stock, measured at the average price of treasury stock held at such date; and the resulting gain or loss is recorded in the consolidated statement of changes in net equity in the caption “Retained earnings”.
Cash and cash equivalents	(af) Cash and cash equivalents - Cash presented in the consolidated statement of cash flows includes cash and due from banks balances with original maturities lower than three months, excludes the restricted funds, which are subject to an insignificant risk of changes in value. The cash and cash equivalent item does not include accrued interest. On the other hand, the cash collateral committed as part of a repurchase agreement is included in the “Cash and due from banks” caption of the consolidated statement of financial position; see Note 4(d).
Reclassification of financial assets and liabilities	(ah) Reclassifications on financial statements as of December 31, 2019 and 2018 – During 2020, the Management performed a detailed analysis on the nature of the products “Renta Particular Plus” and “Renta Particular Plus - Vitalicio”, considering the important growth they have had during the last years; and which were being recorded on “Other accounts payable, provisions and other liabilities”, considering mainly the financial component included in these products. This analysis had the purpose to separate these products based on their main characteristics. In this regard, the product “Renta Particular Plus”, for which a majority of contracts (policies) have an important financial component, remained as a financial liability, while the product “Renta Particular Plus - Vitalicio”, which has a significant insurance component, was determined to reclassify and present it as insurance product according to IFRS 4 (insurance contract liabilities). In this sense, the balances of the product “Renta Particular Plus - Vitalicio” were reclassified from “Other accounts payable, provisions and other liabilities” into the caption “Insurance contracts liabilities” of the consolidated statement of financial position, see Notes 10 and 14, respectively; and its respective effects on income from the captions “Net premiums earned” and “Net claims incurred for life insurance and others” into the caption “Interest and similar expenses” of the consolidated statement of income, see Notes 22 and 19, respectively. Lastly, with the purpose of making comparable the consolidated financial statements, the balances of previous periods were modified, as presented below: Before Reclassification After reclassification S/(000) S/(000) S/(000) Year 2019 Consolidated statement of financial position Insurance contract liabilities 11,338,810 87,821 11,426,631 Other accounts payable, provisions and other liabilities 2,048,048 (87,821 ) 1,960,227 Consolidated statement of income Interest and similar expenses (1,407,897 ) (16,066 ) (1,423,963 ) Net premiums earned 426,608 (5,975 ) 420,633 Net claims and benefits incurred for life insurance contracts and others (722,305 ) 22,041 (700,264 ) Year 2018 Consolidated statement of income Interest and similar expenses (1,170,586 ) (6,708 ) (1,177,294 ) Net premiums earned 328,566 (8,987 ) 319,579 Net claims and benefits incurred for life insurance contracts and others (736,032 ) 15,695 (720,337 ) In Group Management’s opinion, these reclassifications allow a better presentation in the consolidated financial statements.

(**) The variation of the adjustment of technical reserves is due mainly to aging over time; see Note 14(b). (***) In April 2016, the Congress of the Republic of Peru approved the amendment of the Private Pension System Act, through which the affiliates of the Pension Fund Administrators (AFPs) who turn 65 and retire, can choose, among other existing retirement modalities, the return of 95.5 percent of the total fund available from their Individual Capitalization Account (“CIC”, by its Spanish acronym). During 2017, in order to offset the contraction of retirement income as a result of the aforementioned amendment to the SPP Act, Interseguro launched the products “Renta Particular Plus” and “Renta Particular Plus – Vitalicio”, Note 3.4(ah). During 2020 and 2019, premiums collected for “Renta Particular Plus – Vitalicio” amounted to S/30,310,000 and S/40,216,000, respectively, and for “Renta Particular Plus” amounted to S/117,619,000 and S/137,626,000, respectively. As of December 31, 2020, retirement premiums amounted to S/1,750,000 (in 2019 and 2018 retirement premiums amounted to S/3,841,000 and S/10,469,000, respectively). The liability related to “Renta Particular Plus – Vitalicio“ is presented in the caption “Insurance contracts liabilities” of the consolidated statement of financial position considering that it contains an important component of insurance; and the liability of the “Renta Particular Plus” is presented in the caption “Other accounts payable, provisions and other liabilities” of the consolidated statement of financial position considering that it does not contain an important insurance component.

[1]	Corresponds mainly to: (i) the variation between the amortized cost of the loan at the beginning of the year and its amortized cost at the end of the year (partial amortizations that did not represent a reduction or derecognized of the loan), and (ii) the execution of contingent loans (conversion of indirect debt into direct debt).
[2]	With the purpose of reflecting the impact of the uncertainty due to the Covid-19 pandemic, see Note 1(b), the Group decided to apply the expert judgment to perform migrations of clients with higher risk from Stage 1 to Stage 2 and Stage 3, and from Stage 2 to Stage 3. These migrations into higher risk Stages led to incurrence of higher provisions for expected loss during 2020 compared to the year 2019; see Note 30.1(d.4).
[3]	Corresponds mainly to: (i) the variation between the amortized cost of the loan at the beginning of the year and its amortized cost at the end of the year (variation in the provision recorded for partial amortizations that did not represent a reduction or derecognized of the loan), (ii) variations in credit risk that did not generate transfers to other stages; and (iii) the execution of contingent loans (conversion of indirect debt into direct debt).
