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 Change in accounting policy, adoption of new IFRS and disclosures 3.2.1 Change in accounting policy Based on an analysis conducted by Management in 2018, and in application of IAS 8 “Accounting Policies, Changes in Accounting Estimates and Errors”, IFS modified its corresponding figures as of December 31, 2017, and for the year then ended. The amendments made mainly resulted from the following: (i) As of December 31, 2017, the Subsidiary Interseguro recognized in its consolidated statement of income the effect of the change in the value of liabilities coming from retirement, disability and survivor’s pensions, caused by the variation in the market interest rates used to discount these liabilities. In the first quarter of 2018, Management decided to modify its accounting policy in order to show the effect of the change in market interest rates on the statement of other comprehensive income. This change was made to reduce volatility in the profits or losses associated to the effect of changes in market interest rates, as the financial assets supporting such insurance liabilities were measured at fair value through other comprehensive income. According to IAS 8, as the aforementioned change constituted a voluntary change in the accounting policy of the Company and, in compliance with the standard, it was applied retrospectively to previously released balances. In that sense, the Group calculated the accounting effects of the retrospective application of these changes to the balances as of January 1, 2017 and December 31, 2017. The cumulative effect as of those dates were recorded as a decrease in the caption “Unrealized results” and an increase in the caption “Retained earnings” for approximately S/479,476,000 and S/675,095,000, respectively. This accounting policy change was made in accordance with IFRS 4 “Insurance Contracts” and, in Management’s opinion, provides more accurate and relevant information regarding the Group’s insurance contract operations. (ii) The net assets recognized in the consolidated financial statements as of December 31, 2017, as part of the acquisition of Seguros Sura, see Note 9(b), were based in a preliminary fair value assessment. During 2018, the Group completed the review of the fair value of liabilities for insurance contracts as of the acquisition date; and, as result, the identifiable net assets acquired were modified. The Group applied the changes retrospectively to the balances as of December 31, 2017, recording a decrease in the caption “Integibles and goodwill, net” and an increase in the caption “Insurance contract liabilities” for approximately S/195,339,000. 3.2.2 Adoption of new standards and disclosures In these consolidated financial statements, the Group has adopted for the first time IFRS 16 “Leases”, effective for annual periods beginning on or after January 1, 2019. Additionally, the Group early adopted 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, in effect for annual periods beginning on or after January 1, 2020. The application of these amendments implied additional disclosures as described further on this note. Furthermore, since January 1, 2018, the Group is applying: (i) IFRS 15 “Revenue from Contracts with Customers”, which did not present any significant impacts or differences with respect to IAS 18, in relation with the moment at which the Group recognizes revenues or when revenues must be recognized at gross amount, as principal, or net, as agent; and (ii) IFRS 9 “Financial Instruments”, which according to what is allowed by the standard, was applied by the Group without restating the financial statement of the year 2017. Therefore, the information of the year 2017 is presented in accordance with IAS 39 (whose accounting policies are described in Note 3.4(ah)) and it is not comparable to the information of the years 2018 and 2019, which is presented in accordance with IFRS 9. The differences that arose due to the first adoption of IFRS 9 were recognized directly in retained earnings as of January 1, 2018. Other standards, interpretations or amendments have also been adopted for the first time in 2019 but, as of December 31, 2019, they have not had a significant impact on the Group’s consolidated financial statements as described further on this note. The Group has not adopted any standard, interpretation or amendment that has been issued but is not effective, except for the amendments to IFRS 9, IAS 39 and IFRS 7: “Reform of the Reference Interest Rate”, as explained below. • First adoption of IFRS 16 “Leases” IFRS 16 supersedes IAS 17 “Leases”, IFRIC 4 “Determining whether an arrangement contains a lease”, SIC 15 “Operating leases-incentives” and SIC 27 “Evaluating the substance of transactions involving the legal form of a lease”. The standard sets out the principles for the recognition, measurement, presentation and disclosure of leases and requires lessees to recognize most leases in the statement of financial position. Lessor accounting under this new standard is substantially unchanged from IAS 17. Lessors will continue to classify leases as either operating or finance leases using similar principles as in IAS 17. Therefore, IFRS 16 does not have an impact for leases where the Group is the lessor. The Group has adopted IFRS 16 under the retrospective modified approach, throughout an adjustment of the cumulative effect as of January 1, 2019, and not restating amounts from previous periods. The Group chose to apply the standard to all contracts subscribed before January 1, 2019, that were identified as leases according to IAS 17. The Group also elected to use the recognition exemptions for lease contracts that, at the commencement date, have a lease term of 12 months or less, and lease contracts for which the underlying asset is of low value. • Leases previously classified as finance leases - The Group did not change the initial carrying amounts of recognized assets and liabilities at the date of initial application (i.e., the right-of-use • Leases previously classified as operating leases - The Group recognized right-of-use low-value right-of-use The Group also applied the following available practical expedients under IFRS 16: • Used a single discount rate to a portfolio of leases with reasonably similar characteristics. • Relied on its assessment of whether leases are onerous immediately before the date of initial application. • Applied the exemption to leases of short-term and low value assets at the date of initial application. • Excluded the initial direct costs from the measurement of the right-of-use • Used hindsight in determining the lease term where the contract contained options to extend or terminate the lease. Based on the above, the effect of adopting IFRS 16 has been, as follows: Right-of-use-assets Land Buildings and Furniture and Total Lease liabilities S/(000) S/(000) S/(000) S/(000) S/(000) As of January 1, 2019 56,657 285,089 — 341,746 341,746 Additions 9,489 55,179 2,292 66,960 66,960 Depreciation expense of right-of-use (2,235 ) (71,028 ) (477 ) (73,740 ) — Interest expense — — — — 16,568 Payments — — — — (83,438 ) As of December 31, 2019 63,911 269,240 1,815 334,966 341,836 As of January 1, 2019, the adoption of IFRS 16 has not had any impact neither on the consolidated statement of income nor on the consolidated statement of changes in equity. The following table presents the reconciliation of the initial balance of lease liabilities as of January 1, 2019, against the balance of operating lease commitments as of December 31, 2018: S/(000) Assets Operating lease commitments as of December 31, 2018 511,595 Weighted average incremental borrowing rate as of January 1, 2019 5.58 % Discounted operating lease commitments as of January 1, 2019 345,259 Less: Commitments relating to leases of short-term and low-value (3,513 ) Lease liabilities as of January 1, 2019 341,746 • Interpretation of IFRIC 23 “Uncertainty over Income Tax Treatments” The Interpretation addresses the accounting for income taxes when tax treatments involve uncertainty that affects the application of IAS 12 “Income Tax”. The Interpretation does not apply to taxes or levies outside the scope of IAS 12, nor does it specifically include requirements relating to interest and penalties associated with uncertain tax treatments. The Interpretation specifically addresses the following: • Whether an entity considers uncertain tax treatments separately. • The assumptions an entity makes about the examination of tax treatments by taxation authorities. • How an entity determines taxable profit (tax loss), tax bases, unused tax losses, unused tax credits and tax rates. • How an entity considers changes in facts and circumstances. IFS has to determine whether to consider each uncertain tax treatment separately or together with one or more other uncertain tax treatments. The approach that better predicts solving the uncertainty should be followed. Although IFS and its Subsidiaries domiciled in the Republic of Panama and the Bahamas are not subject to any income tax or capital gains tax, see Note 17(a), and Peruvian companies of life insurance are exempted 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, see Note 17(e), the Group determined, based on the compliance of its tax obligations and the assessment of transfer prices, that it is probable that other taxing treatments (including those of the Subsidiaries) may be accepted by the tax authorities. This interpretation did not have any impact on the Group’s consolidated financial statements. • Amendments to IFRS 9: Prepayment features with negative compensation Under IFRS 9, a debt instrument can be measured at amortized cost or at fair value through other comprehensive income, provided that the contractual cash flows are ‘solely payments of principal and interest on the principal amount outstanding’ (the SPPI criterion) and the instrument is held within the appropriate business model for that classification. The amendments to IFRS 9 clarify that a financial asset passes the SPPI criterion regardless of the event or circumstance that causes the early termination of the contract and irrespective of which party pays or receives reasonable compensation for the early termination of the contract. The early termination may be the result of a contractual term or result from an event outside the control of the contract parties, such as a change in legislation or the enactment of regulation that leads to the early termination of the contract. When the advance payment is made at the current fair value or at an amount that includes the fair value of the cost of terminating the associated hedging instruments, the Group assesses the specific contractual cash flows for the relevant debt instruments with the purpose of determining whether they comply with the SPPI criterion. The Group has performed the analysis of these amendments, and has concluded that they did not have a significant effect on its consolidated financial statements. • Amendments to IAS 28: Long-term interests in associates and joint ventures The amendments clarify that an entity applies IFRS 9 to long-term interests in an associate or joint venture to which the equity method is not applied but that, in substance, form part of the net investment in the associate or joint venture (long-term interests). This clarification is relevant because it implies that the expected credit loss model in IFRS 9 applies to such long-term interests. The amendments also clarified that, in applying IFRS 9, an entity does not take account of losses of the associate or joint venture, or impairment losses on the net investment, recognized as adjustments to the net investment in the associate or joint venture that arise from applying IAS 28 “Investments in Associates and Joint Ventures”. Since the Group does not have such long-term interests in its associates and joint ventures, the amendments had no impact on its consolidated financial statements. • Amendments to IAS 19: Plan amendment, curtailment or settlement The amendments to IAS 19 “Employee Benefits” address the accounting when a benefits plan amendment, curtailment or settlement occurs during a reporting period. The amendments specify that when a benefits plan amendment, curtailment or settlement occurs during the annual reporting period, an entity is required to determine the cost of current services for the period remaining after the plan amendment, curtailment or settlement has occurred, using the actuarial assumptions used to remeasure the net defined benefit liability (asset) reflecting the benefits offered under the plan and the plan assets after that event. It is also required that an entity determines the net interest for the remainder of the period after the plan amendment, curtailment or settlement using the net defined benefit liability (asset) reflecting the benefits offered under the plan and the plan assets after that event; and the discount rate used to remeasure that net defined benefit liability (asset). The Group has analyzed these modifications, concluding that they did not have an impact on its consolidated financial statements. • Improvements to the IFRS (2015 – 2017 cycle) • IFRS 3 “Business Combinations”, the amendments clarify that, when an entity obtains control of a business that is a joint operation, it applies the requirements for a business combination achieved in stages, including remeasuring previously held interests in the assets and liabilities of the joint operation at fair value. In doing so, the acquirer remeasures its entire previously held interest in the joint operation. In Management’s opinion, these modifications had no impact on the Group’s consolidated financial statements. • IFRS 11 “Joint Arrangements”, a party that participates in, but does not have joint control of, a joint operation might obtain joint control of the joint operation in which the activity of the joint operation constitutes a business as defined by IFRS 3. The amendments clarify that the previously held interests in that joint operation are not remeasured. In Management’s opinion, these modifications will have no impact on the Group’s financial statements because they do not perform joint operations. • IAS 12 “Income Taxes”, the amendments clarify that the income tax consequences of dividends are more directly linked to past transactions or events that generated distributable profits than to distributions to owners. Therefore, an entity recognizes the income tax consequences of dividends in profit or loss, in other comprehensive income or in equity, according to where the entity originally recognized those past transactions or events. Although IFS and its Subsidiaries domiciled in the Republic of Panama and the Bahamas are not subject to any income tax or capital gains tax, see Note 17(a), and Peruvian companies of life insurance are exempted 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, see Note 17(e); legal entities or natural persons not domiciled in Peru are subject to an additional tax on dividends received from entities domiciled in Peru. In this regard, since the Company controls the Subsidiaries that distribute the dividends, it recognizes the amount of the Income Tax as an expense for the year to which these dividends correspond. In this sense, the application of the interpretation will not affect the consolidated financial statements. • IAS 23 “Borrowing Costs”, the amendments clarify that an entity treats as part of general borrowings any borrowing originally made to develop a qualifying asset when substantially all of the activities necessary to prepare that asset for its intended use or sale are complete. In Management’s opinion, these modifications had no significant impact on the Group’s consolidated financial statements because they do not develop qualified assets or obtain financing for these purposes. • Amendments to IFRS 9, IAS 39 and IFRS 7: “Interest rate benchmark reform” After the worldwide regulation change, the inter-bank offering rates (IBOR) will be replaced by new interest rate benchmarks by 2021. The amendments originated by the Interest rate benchmark reform with impact on IFRS 9, IAS 39 and IFRS 7 add a series of exemptions that apply to all affected hedging relationships. A hedging relationship will be affected if the reform generates uncertainty about the moment or the amount of the cash flows related to the hedged account of the hedging instrument in the period prior to the replacement of the rate benchmark with the alternate rate benchmark, given that this rate can be almost risk free. The exceptions provided by the amendments are: • “Highly probable” requirement for cash flow hedges: If the hedged item is a forecast transaction, it will be determined that the forecast transaction is highly probable by assuming that the interest rate benchmark upon which the hedged cash flows are based is not altered as a result of the interest rate benchmark reform. • Reclassification to statement of income of the cash flow hedge reserve: In order to determine if it is not expected that the hedged cash flows occur, it is assumed that the interest rate benchmark upon which the hedged cash flows are based is not altered as a result of the interest rate benchmark reform. • Economic relationship between the hedged item and the hedge instrument: It is assumed that the interest rate benchmark upon which the hedged cash flows are based, and/or the interest rate benchmark upon which the cash flows of the hedge instrument are based, is not altered as a result of the interest rate benchmark reform. The amendments have the intention of avoiding any disruption in the existing relationships in the hedge accounting of cash flows and the fair value of interest rate risk which, in the absence of said amendments, would result in the ineffectiveness of the hedge and potential inconsistencies in the hedge accounting as a result of the interest rate benchmark reform. Specific impacts are expected on the hedge accounting as a result of the interest rate benchmark reform for future accounting periods once the second phase of IASB’s project, which is centered on the financial report, is finished. In that sense, the Group has started a transition process for these operations by collecting information of the relevant positions. At the end of the 2019 period, the Group has exposure to mainly US$-Libor rates; thus, the impact will be the potential change into another interest rate benchmark. The main affected items within the Group will be derivative positions (interest rate swaps – IRS, and cross currency swaps – CCS, outstanding as of the transition date which accrue US$-Libor interest). Additionally, the Group holds some financial instruments with exposure to the inter-bank Euribor rate (Euro Interbank Offered Rate). The calculation methodology of Euribor changed during the year 2019 through the adoption of a hybrid methodology based mainly and to the extent possible, on observable market data and, in case these are not sufficient, on other market price sources, in order to ensure the strength of the Euribor inter-bank rate. In July 2019, the Belgian Authority of Financial Services and Markets granted an authorization regarding the applicability of the Euribor inter-bank rate under the European Union Benchmark Regulation, thus allowing market participants to continue using this rate after January 1, 2020, for both existing and new contracts. The Group expects that the Euribor inter-bank rate will continue existing as rate benchmark in the foreseeable future. Because of this, the Group does not consider that this index benchmark may be directly affected as result of the interest rate benchmark reform. Note 10(b)(vi) details the nominal value and the average term in years of derivative financial instruments that are subject to the interest rate benchmark reform. 3.3 Basis of consolidation - The consolidated financial statements comprise the financial statement of IFS and its Subsidiaries (see Note 2). For 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 circumstances when the Group does not have the majority of voting 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 for 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, within 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, as is the interest income of the financial assets that accrue interests classified as available-for-sale held-to-maturity The EIR (and, therefore, the amortized cost of the financial asset) 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 in the consolidated statement of financial position as a positive or negative adjustment of the carrying amount of the financial asset with a 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, the Group calculates the interest income by determining the credit-adjusted EIR at the amortized cost of the asset, as established in Note 30.1(d). 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 within 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 Bank 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 that the Group expects to be entitled to, in exchange for providing its 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 customers, consideration is invoiced and generally due immediately upon satisfaction of a service provided at a specific point in time. For cases in which services are provided over time, consideration is invoiced and generally due at the end of the contract period. 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. Fee income where performance obligations are satisfied over a period 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 are the main income categories 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: For the adoption of IFRS 4 “Insurance Contracts”, the Group decided to continue applying to insurance contracts the existing accounting policies that were applicable 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 were 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 for 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 In the year 2018, the Company adopted these new mortality tables because they reflected recent changes in life expectancy. 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 Adjustment” 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.

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/6,790,000 during the year 2019 and a reversal of the impairment of S/13,077,000 during the year 2018, which were 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 Also, as result of the impairment assessment of its available-for-sale available-for-sale non-controlling (d) As of December 31, 2019 and 2018, investments at amortized cost are entirely comprised of Sovereign Bonds of the Republic of Peru issued in Soles, for an amount of S/2,206,986,000 and S/1,884,067,000, respectively, including accrued interest. Said investments present low credit risk and the expected credit loss is not significant. As of December 31, 2019, 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 6.26 percent, and estimated fair value amounting to approximately S/2,328,303,000 (as of December 31, 2018, their maturity dates ranged from August 2020 to August 2037, accrued interests at effective annual rates between 4.05 percent and 6.33 percent, and its estimated fair value amounted to approximately S/1,856,325,000). 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 its fiscal deficit. Considering the purpose of this offering, following such offering, there would be no outstanding sovereign bonds of the repurchased issuances. In the event that some bonds remained outstanding, 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 within 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. On the other hand, in accordance with IAS 39, in force until December 31, 2017, Interbank reclassified from the year 2015 to the year 2017, Peruvian sovereign bonds from available-for-sale held-to-maturity As of December 31, 2019 and 2018, Interbank keeps loans with the BCRP that are guaranteed with these sovereign bonds of the Republic of Peru, classified as restricted, for approximately S/762,347,000 and S/738,635,000, respectively; see Note 12(b).

During 2018, main additions are outlays related to the construction of the buildings “Orquídeas” (San Isidro) and “Chorrillos” (both located in Lima). During 2017, main additions correspond to the acquisition of a percentage of a land lot located in Miraflores, Lima (called “Cuartel San Martin”), for approximately S/48,600,000 from a related entity; a building located in Chorrillos, Lima, for approximately S/26,550,000, acquired from third parties; and another building located in Cusco for approximately S/22,515,000 acquired from a related entity. The latter two amounts include subsequent disbursements related to the construction of said buildings. (e) During 2019, Interseguro sold to related entities, in cash and at market value, two land lots located in Miraflores and Huaral. Likewise, Interseguro sold to third parties, in cash and at market value, an educational center and offices located in San Juan de Lurigancho and San Isidro. 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. The following shows 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 5,100 8,200 6,000 San Martin de Porres – Lima 1,433 1,600 1,540 Piura 850 1,000 1,105 Others 322 384 373 Main assumptions A brief description of the assumptions considered in the determination of cash flows as of December 31, 2019 and 2018, is presented below: • ERV (Estimated Rental Value) - Corresponds to the Estimated Rental Value, which is the rent under the market conditions prevailing at the date of valuation. • 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 2019 2018 Average ERV US$ 88.7 US$ 67.6 Long-term inflation 2.6 % 2.6 % Long-term occupancy rate 99.3 % 98.9 % Average growth rate of rental income 2.6 % 2.6 % Average NOI margin 93.8 % 95.3 % Discount rate 8.7 % 9.0 % Sensitivity analysis - The sensitivity analysis on the valuation of investment property, against changes in factors deemed relevant by Management, is presented below: 2019 2018 S/(000) S/(000) Average growth rate of rental income (basis) - Increase +0.25 % 16,045 14,836 Decrease -0.25 % (15,306 ) (13,964 ) Long-term inflation (basis) - Increase +0.25 % 15,132 14,081 Decrease -0.25 % (13,906 ) (12,949 ) Discount rate (basis) - Increase +0.5 % (43,733 ) (36,422 ) Decrease -0.5 % 51,703 42,485 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) Future minimum fixed rental income of the Group’s investment property (operating leases) are as follows: Year 2019 2018 S/(000) S/(000) Within 1 year 40,920 34,753 After 1 year but not more than 5 years 149,263 138,016 Over 5 years 689,715 657,485 Total 879,898 830,254 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, 2019, 2018 and 2017. (b) Acquisition of Seguros Sura, Hipotecaria Sura and Goodwill Acquisition of Seguros Sura In November 2017, IFS acquired 99.39 percent of Seguros Sura’s capital stock and 99.42 percent of Hipotecaria Sura’s capital stock. The aforementioned acquisition, included the purchase of 9.19 percent of Seguros Sura’s capital through Interseguro, while 30.10 percent of Seguros Sura’s capital stock and 29.40 percent of Hipotecaria Sura’s capital stock was acquired through the purchase of the companies Negocios e Inmuebles S.A. and Holding Retail Perú S.A. On the other hand, and in accordance with the legal regulations in force in Peru, the SBS granted a six-month Goodwill - 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 generating 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, 2019 and 2018, the key assumptions used for the calculation of fair value are: • Perpetuity growth rate: 4.5%. • Discount rate: 12.0%. 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, 2019 and 2018, 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(f), 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.

(**) In July 2019, Interbank early redeemed the entirety of these subordinated bonds. Also, in February 2019, Interseguro executed the early amortization of said instruments. (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) 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, 2019, Management does not intend to redeem these bonds before their maturity date; said situation may change in the future, depending on market conditions. (d) Starting in April 2020, the applicable interest rate will be a floating rate of 3-month non-cumulative non-compliance This issuance qualifies 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 qualifies as second level equity (Tier 2); see Note 16(f). Interbank’s Board Session held on January 28, 2020, agreed to redeem the entirety of these instruments. According to the aforementioned, Interbank obtained SBS approval to execute the optional redemption of the entirety of these bonds, which will be redeemed on April 23, 2020 for USD208,500,000. Such amount includes the principal plus interest accrued up to that date. (e) 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 into a cross currency swap for US$150,000,000 (As of December 31, 2019 and 2018, equivalents to approximately S/497,100,000 and S/505,950,000, 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, 2019, Management does not intend to redeem these bonds before their maturity date; said situation may change in the future, depending on market conditions. (f) Corresponds to a senior bond issued by Interbank through its Panama branch. Starting in April 2016, Interbank can redeem these bonds, at the coupon payment date, paying a penalty equal to the United States Treasury rate plus 50 basis points. The nominal annual interest rate of these instruments was 5.75 percent. In this regard, Management identified that the interest rates had decreased significantly compared to the interest rates that these bonds accrued; thus, during the first quarter of 2018, Interbank identified an opportunity to generate financial savings and decided to perform a partial swap of these bonds; see paragraph (g); and, for the remaining balance, the Bank performed a buyback offering in cash of the entirety of these bonds in September 2019; see paragraph (i). In June 2017, Interbank entered into cross currency swaps for US$20,000,000 (equivalent to approximately S/67,660,000, which up until December 31, 2018, were designated as cash flow hedges; see Note 10(b). Through these operations, part of the issued amount of these bonds was economically converted into Soles at a rate of 4.61 percent. However, as result of the buyback performed by Interbank in July 2019 and the subsequent redemption of these bonds, Interbank revoked the accounting hedge. Consequently, the balance of the net unrealized loss of the Income Tax accumulated in the caption “Cash flow hedges reserves” of the consolidated statement of changes in equity as of the revocation date, amounting to S/1,105,000, was transferred to caption “Net gain of financial assets through profit or loss” of 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 (see (f) above), managing to exchange bonds for an amount to US$263,322,000, which generated an exchange premium of approximately US$21,573,000 that 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, 2019, Interbank maintains fourteen cross-currency swaps for a total of US$441,000,000 (equivalent to approximately S/1,461,474,000), which were designated as cash flow hedges (eleven cross-currency swaps for US$400,000,000 equivalent to approximately S/1,349,200,000 as of December 31, 2018); 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, 2019, Management does not intend to redeem these bonds before their maturity date; said situation may change in the future, depending on market conditions. (h) 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. (i) 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 (see paragraph (f) above); 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. (j) 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, 2019 and 2018, 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 Management and its legal advisers, this clause has been met by the Group as of December 31, 2019 and 2018. (k) As of December 31, 2019 and 2018, the repayment schedule of these obligations is as follows: Year 2019 2018 S/(000) S/(000) 2019 — 132,512 2020 235,128 1,309,248 2021 — — 2022 136,908 137,900 2023 onwards 6,518,254 4,917,118 Total 6,890,290 6,496,778

(e) The main assumptions used in the estimation of retirement, disability and survival annuities and individual life reserves as of December 31, 2019 and 2018, are the following: Type Mortality table Interest rates 2019 2018 Annuities SPP-S-2017, SPP-I-2017 with improvement factor for mortality 4.54% in US$ 1.89% in S/ VAC 5.10% in adjusted S/ 5.63% in US$ 2.74% in S/ VAC 5.84% in adjusted S/ Retirement, disability and survival SPP-S-2017, SPP-I-2017 with improvement factor for mortality 1.89% in S/ VAC 2.74% in S/ VAC Individual life insurance contracts (included linked insurance contracts) CSO 80 adjusted 4.00 - 5.00% 4.00 - 6.00% The sensitivity of the estimates used by the Group to measure its insurance risks is represented primarily by life insurance risks; the main variables as of December 31, 2019 and 2018 are the interest rates and the mortality tables. The Group has assessed the changes of the reserves related to its most significant life insurance contracts included in the reserves of annuities, retirement, disability and survival of +/- 100 basis points (bps) in the interest rates and of +/- 500 basis points (bps) of the mortality factors, being the results as follows: 2019 2018 Variation of the reserve Variation of the reserve Variables Reserves Amount Percentage Reserves Amount Percentage S/(000) S/(000) % S/(000) S/(000) % Annuities - Portfolio in S/ and US Dollars - basis amount Changes in interest rate: + 100 bps 8,646,725 (1,006,695 ) (10.43 ) 7,816,973 (848,921 ) (9.80 ) Changes in interest rate: - 100 bps 10,890,170 1,236,750 12.81 9,696,893 1,030,999 11.90 Changes in mortality table at 105% 9,554,268 (99,152 ) (1.03 ) 8,587,633 (78,261 ) (0.90 ) Changes in mortality table at 95% 9,757,493 104,073 1.08 8,747,817 81,923 0.95 Retirements, disability and survival - Portfolio in S/ – basis amount Changes in interest rate: + 100 bps 687,451 (92,004 ) (11.80 ) 635,838 (79,379 ) (11.10 ) Changes in interest rate: - 100 bps 894,614 115,159 14.77 813,614 98,397 13.76 Changes in mortality table at 105% 769,044 (10,411 ) (1.34 ) 706,495 (8,722 ) (1.22 ) Changes in mortality table at 95% 790,403 10,948 1.40 724,366 9,149 1.28

As of December 31, 2019 and 2018, 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 Central Bank of the Bahamas). In the case of Hipotecaria Sura, as of December 31, 2018, it was under liquidation process, thus it was not subject to regulatory minimum capital requirements. It was liquidated on February 20, 2019. The regulatory capital required for Interbank, Interseguro and Inteligo Bank is detailed below: Interbank’s regulatory capital - According to the provisions of 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, 2019 and 2018, Interbank maintains the following amounts related to its assets and contingent credits weighted by risk and regulatory capital (basic and supplementary): 2019 2018 S/(000) S/(000) Total risk weighted assets and credits 50,673,786 44,390,985 Total regulatory capital 7,679,278 7,007,381 Basic regulatory capital (Level 1) 5,721,707 5,042,037 Supplementary regulatory capital (Level 2) 1,957,571 1,965,344 Global capital to regulatory capital ratio 15.15 % 15.79 % As of December 31, 2019 and 2018, 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, 2019 and 2018, the additional regulatory capital estimated by Interbank amounts to approximately S/803,717,000 and S/735,483,000, respectively. 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, 2019 and 2018, 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, 2019 and 2018, Interseguro’s surplus equity is as follows: 2019 2018 S/(000) S/(000) Regulatory capital 1,106,609 1,042,699 Less Solvency equity (solvency margin) 567,348 559,930 Guarantee fund 198,572 195,975 Surplus 340,689 286,794 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, 2019 and 2018 is the following: 2019 2018 US$(000) US$(000) Total eligible capital 238,281 216,977 Total risk weighted assets 964,156 850,069 Capital adequacy ratio (in percentage) 24.71 25.52 In Management’s opinion, its Subsidiaries have complied with the requirements set forth by the regulatory entities. (g) Reserves - 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. The Board of Directors of IFS session held on September 18, 2017, agreed to constitute a reserve of up to S/600,000,000 charged to retained earnings as of June 30, 2017. Likewise, the Board of Directors of IFS session, held on August 9, 2017, agreed to constitute a reserve of up to S/500,000,000 charged to retained earnings as of December 31, 2016. (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; nevertheless, IFS is subject to an additional tax on dividends received from its Subsidiaries incorporated and domiciled in Peru; see paragraph (b). The Subsidiaries incorporated and domiciled in Peru (see Note 2) are subject to the Peruvian Tax legislation; see paragraph (c). (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, 2019 and 2018, the Company has recorded expenses for S/36,361,000 and S/37,880,000, respectively, in the caption “Income Tax” of the consolidated statement of income. (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, 2019, 2018 and 2017, was 29.5 percent, over the taxable income. On the other hand, there are considered as Peruvian-source income those arisen from the indirect sale of shares of stock or ownership interests of legal entities domiciled in the country. 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. The law also defines the cases in which the issuer is jointly and severally liable thereof. (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. The Income Tax and the Value-Added-Tax • Interbank: Income Tax returns for the years 2014 to 2019, and Value-Added-Tax • Interseguro: Income Tax returns for the years 2014 to 2019, and Value-Added-Tax • Hipotecaria Sura and Seguros Sura: Income Tax returns for the years 2014 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 detail of the 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 in the Tax Court. 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, the Bank 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. 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 with another financial entity, ruled in favor of the tax treatment over the interest in suspense followed by said entity; which is consistent with the tax treatment followed by Interbank. Lastly, on March 12, 2020, the Permanent Chamber of Constitutional and Social Law of the Supreme Court published on the website of the Judiciary its ruling regarding Interbank’s Income Tax for the year 2003, declaring groundless the cassation appeals filed by SUNAT and the Ministry of Economy and Finance (“MEF”, by its Spanish acronym), thus reaffirming the position held by the Bank regarding that interest in suspense does not constitute taxable income. From the tax and legal analysis performed, reinforced by the aforementioned recent ruling by the Permanent Chamber of Constitutional and Social Law of the Supreme Court, Interbank’s Management and its external legal advisors consider that it exists sufficient technical support for the prevalence of Interbank’s position, in relation with the tax periods under resolution process; thus, it has not been recorded any provision for this contingency as of December 31, 2019 and 2018. The tax liability requested for this concept and other minor contingencies as of December 31, 2019, without considering the effects of the ruling by the Permanent Chamber of Constitutional and Social Law of the Supreme Court published on March 12, 2020, amounted to approximately S/303,000,000, out of which S/34,000,000 corresponded to taxes and the difference to fines and interest arrears. However, it is estimated that once SUNAT performs the resettlements of the Income Tax, including the effects of said ruling, the requested amount will diminish significantly. On the other hand, on February 3, 2017, SUNAT closed the audit process corresponding to the Income Tax for the year 2010. The Bank 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 February 14, 2018, SUNAT notified Interbank of the beginning of the partial audit process for the third category Income Tax corresponding to the year 2014. Subsequently, on September 7, 2018, SUNAT closed said partial audit process and did not determine any additional settlement of said tax. 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. As of December 31, 2019, the tax debt requested by SUNAT amounts to approximately S/50,000,000 (including taxes, penalties and moratorium interest). The main concept observed was the deduction of loan write-offs without proof by the SBS. To date, Interbank’s Management has submitted the respective complaints to the resolutions indicated above. In the opinion of Management and its legal advisors, any eventual additional tax would not be significant for the financial statements as of December 31, 2019 and 2018. On April 26, 2019, SUNAT notified Interbank about the commencement of the definitive audit process on Income Tax withholdings of non-domiciled On September 11, 2019, SUNAT notified Interbank about the commencement of the definitive audit process on the Income Tax corresponding to the year 2014. To date, said audit is under process. On December 12, 2019, SUNAT notified Interbank about the commencement of the definitive audit process on the Income Tax corresponding to the year 2015. To date, said audit is under process. Lastly, to date, SUNAT is auditing Interbank’s 2012 taxable period. In the opinion of Management and its legal advisors, any eventual additional tax settlement would not be significant for the financial statements as of December 31, 2019 and 2018. Interseguro: On January 4, 2019, Interseguro was notified through a Tax Determination notice about the partial audit of the Income Tax for non-domiciled On August 28, 2019, Interseguro was notified by SUNAT through requirement letter related to the Income Tax of the taxable period 2008 as definitive tax audit commenced regarding Seguros Sura. (e) 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. (f) 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: (i) Local Report; (ii) Master Report; and (iii) Country Report. The first validity entered into effect in 2017 for the operations that occurred during 2016 and the last two as of 2018 for the operations that have occurred since the fiscal year 2017. (g) Through Legislative Decree No.1381, published on August 24, 2018, incorporated in the Income Tax Act the concept of “non-cooperating” In this regard, it is important to emphasize that, at present, Interbank maintains a branch in Panama, a country that is considered “non-cooperating”, (h) 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 for when the tax debtor is subject to the application of the measures provided by Rule XVI and in the event that tax evasion cases are detected. In such cases, the joint and several liability shall be attributed to the legal representatives provided that they have collaborated with the design, approval or execution of actions or situations or economic relations viewed as evasion 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 credit (corporate tax paid by foreign subsidiaries) as credit applicable against the Income Tax of domiciled legal persons, in order to avoid double taxation. • The deduction of interest expenses for the determination of corporate Income Tax. In the years 2019 and 2020, 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 as of September 14, 2018. Beginning in 2021, 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 as of 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.

The Group applies the same credit policies for granting and evaluating the provisions required for direct loans when performing contingent operations (see Note 6(a)), including obtaining guarantees when deemed necessary. 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. (c) Responsibilities under credit lines agreements include consumer credit lines and other consumer loans that are cancellable by the Bank. (d) Corresponds to commitments of disbursement of future loans that Interbank has committed to carry out; provided that the borrower complies with the obligations under the corresponding loan agreements, however, they may be cancelled by Interbank.

(**) The variation of the adjustment of technical reserves is due mainly to aging over time; see Note 14(b). (***) As part of the Private Pension System reform that started in 2013, as regards to the coverage of survival and disability of the pension insurance, the affiliates portfolio was divided into seven parts so that insurance companies manage obligations and rights as a whole. In this way, when an affiliate needs a pension from the pension insurance, the pension will be divided into seven parts and each insurance company will have to assume a corresponding part. This coverage is allocated through a public tender. In December 2016, the call for the “Third Public Tender No. 03/2016” was made to cover the period from January 1, 2017, to December 31, 2018. As result of said process, Interseguro did not win the allocation, but Seguros Sura was awarded a seventh part of this coverage, which is 70 percent reinsured. In November 2018, the call for the “Fourth Public Tender No. 04/2018” was made, to cover the period from January 1, 2019, to December 31, 2020, and as result of this process, the company was not awarded any coverage. (****) In April 2016, the Congress of the Republic of Peru approved the amendment of the SPP 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 “Renta Particular Plus”; Note 10(a), product and raised funds from said product as of December 31, 2019 and 2018, for S/177,842,000 and S/174,632,000, respectively. This allowed to maintain the product portfolio level and the long-term cash fundraising. As of December 31, 2019, retirement premiums amounted to S/3,841,000 (in 2018 and 2017, amounted to S/10,469,000 and S/24,786,000, respectively).

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 described risks, every Subsidiary of the Group has a specialized structure and organization in their management, measurement systems, mitigation and coverage processes that considers the specific needs and regulatory requirements to develop 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 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.

The Committee is led by an Independent Director, who cannot lead any other Committee within Interseguro. The Committee sessions can be attended by the CEO, 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 CEO. 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 a number of Board Members, the CEO 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. These committees are engaged in managing these risks and in making periodic reviews. (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. (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. Credit risk exposures 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. Until December 31, 2017, the Impairment allowances were established for losses that have been incurred as of the date of the consolidated statement of financial position under IAS 39; and from January 1, 2018, impairment allowances are established for expected credit losses at the date of the consolidated statement of financial position under IFRS 9. 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. Such risks are monitored on a revolving basis and subject to frequent reviews. 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 guarantees: 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 collaterals received for 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. • Without previous obligations that could reduce their value. • 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, 2019 and 2018, 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, 2019 and 2018: • 80.4 percent and 79.8 percent, respectively, of cash and due from banks represent amounts deposited in the Group’s vaults or in the BCRP; • 89.3 percent and 89.0 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); • 91.8 percent and 92.2 percent, respectively, of the loan portfolio is deemed non-past-due non-impaired; • 89.8 percent and 90.0 percent, respectively, of investments at fair value through other comprehensive income and investments at amortized cost have at least an investment grade (BBB- • 92.3 percent and 98.2 percent, respectively, of accounts receivable from insurance premiums and leases of the investment properties is deemed non-past non-impaired. • In addition, as of December 31, 2019, the Group holds loans (direct and indirect) and investments in fixed income instruments issued by entities related to the infrastructure sector that, in recent months, have been exposed to local and international events, for an amount of approximately 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 (S/861,544,000 (S/50,434,000 in direct loans and S/811,110,000 in indirect loans) and S/874,618,000, respectively, as of December 31, 2018). The performance of these instruments will depend on the future development of the aforementioned events, which are out of the Group control. However, it is important to mention that none of the instruments had a significant negative change in the credit category at the date of this report and have guarantees and hedging that significantly reduce the credit risk. (d) Impairment assessment for loan portfolios (Policy applicable from January 1, 2018) - 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 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) credits related to stand-by • Debt instruments measured at amortized cost or at fair value through other comprehensive income. Expected credit losses are estimated collectively for each loan portfolio with shared credit 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 together 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): It represents the total value that the Group can lose upon default of a counterpart.- (d.1) Definition of default: Credit-impaired financial assets are defined by IFRS 9 in a manner similar to credit-impaired financial assets according to IAS 39. 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. • Data elaborated 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 credit risk since initial recognition or they have shown impairment when analyzed, 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 loan portfolio is 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) Interbank’s Credit Risk Department determines its internal credit rating models in the following manner as of December 31, 2019 and 2018: Banking Segment High grade Standard grade Grade lower than PD less than or equal to: PD Range PD equal or higher Personal Banking 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 % 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 % 9.48 % 9.49% - 20.77% 20.78 % 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 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 Default Personal banking: Credit cards X Mortgage With cure X Without cure X Payroll loan X Consumer X Vehicular X Small business banking X Commercial banking With cure and without rating X Without cure and with rating 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. Additionally, as it happens for direct credits, the expected loss for indirect loans (contingent loans) is calculated at each reporting date, depending on the stage in which each operation is found; 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, 2019 and 2018, 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. At Inteligo Bank, both for Personal Banking and Commercial Banking, the internal model developed (scorecard) assigns 5 levels of credit risk: low risk, medium low risk, medium risk, medium high risk, and high risk. This methodology follows a three-phase approach to assess 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. To estimate the PD for the lifetime of a financial asset, a transformation of the PD to 12-months (d.2) 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) 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, 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 point to it. 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 PD to 12 months to the date of origin and the PD to 12 months to the date of the report adjusted by the forward-looking factor, according to the quantitative criteria of absolute variation and relative variation. The Group has established a range of absolute variation between 1 and 7 percent and a relative variation between 20 and 350 percent, depending on the type of portfolio. The Group periodically evaluates the following warning signs and criteria to assess whether the placement presents a significant increase in credit risk (stage 2): • 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 collaterals (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 will monitor 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; • The average time between the identification of a significant increase in credit ri

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. Fair value is estimated using a discounted cash flow (DCF) model. 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. 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 Sales forecast Average 10 percent increase (decrease) in the sales forecast would result in increase (decrease) in fair value by S/10,307,000. 500 basis points increase in the WACC would result in decrease in fair value by S/16,587,000. WACC 8.0% 500 basis points decrease in the WACC would result in increase in fair value by S/23,171,000. Mutual funds and investment funds participations DCF Method Discount rate Depends 500 basis points increase in the discount rate would result in decrease in fair value by S/3,162,000. 500 basis points decrease in the discount rate would result in increase in fair value by S/4,103,000. WACC 9.0% 500 basis points increase in the WACC would result in decrease in fair value by S/686,000. 500 basis points decrease in the WACC would result in increase in fair value by S/812,000. Comparable Price-to-sales Depends 10 percent increase (decrease) in the price-to-sales Equity value Depends 500 basis points increase (decrease) in the equity value would result in increase (decrease) in fair value by S/3,000.

Based on this evaluation, allowances are taken into account for the estimated losses of these loans. As of December 31, 2019 and 2018, 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.

Fiduciary activities and management of funds The Group provides custody, trustee, investment management and advisory services to third parties; therefore, the Group makes purchase and sale decisions in relation to a wide range of financial instruments. Assets that are held in trust are not included in the consolidated financial statements. These services give rise to the risk that the Group could eventually be held responsible of poor yielding of the assets under its management.

Subsequent events	33. Subsequent events (a) Since the balance sheet date, a novel strain of coronavirus (COVID-19) has spread first in China and then in other countries. As a result, on March 3, 2020, COVID-19 was characterized as a pandemic by the World Health Organization. Such events have caused disruption of regional and global economic activity, suspension of international flights and the shutdown of countries’ borders. In relation to the COVID-19 global pandemic, IFS has put into effect a business continuity program since early March 2020, with actions involving different levels of the organization. Supporting these actions, the Peruvian Government and several authorities at the economic front – such as the BCRP, the SBS, the MEF and the Securities Market regulatory body – have all reacted promptly to tackle the crisis. IFS is closely monitoring the situation in all its different business lines, and management is focused on guaranteeing the operation and strengthening the Subsidiaries’ liquidity and solvency position, while adopting a series of measures to help clients affected by this crisis. With respect to liquidity, Interbank has remained active in the Central Bank’s day-to-day operations and has drawn lines of credit available from correspondent banks abroad, while its retail deposit base has continued to grow. Moreover, Interbank has already approved a reduction in its 2019 earnings’ payout ratio, from the previous 45 percent to 25 percent, in order to strengthen its total capital and core capital ratios to face the volatile environment. First quarter of 2020 earnings have also been agreed to be capitalized in advance at the bank level. People and clients’ well-being are top priorities for IFS. On one hand, employees are subject to specific protocols – including social distancing, hygiene habits, health surveillance, home office implementation and strong communications for high engagement. On the other hand, clients can request the rescheduling of their debts and may postpone their payment obligations under various arrangements, with no interest or fees applicable. Non-contact service channels (telephone banking and internet) play an important role in enabling quick and simple implementations of these arrangements. The impact of the COVID-19 outbreak on our expected results of operations cannot be reasonably estimated at this time given the magnitude, duration and global reach of the situation. (b) In 2019, The Universal Shareholders’ Meeting of Interseguro approved a transaction between Interseguro and Mapfre Perú Vida Compañía de Seguros y Reaseguros S.A. (henceforth “Mapfre”) through which Interseguro committed to acquire certain assets and liabilities, related to payment obligations that Mapfre held with pensioners of the Complementary Insurance for High-risk Activities (“SCTR”, by its Spanish acronym). In this sense, through Resolution No. 47315–2019-SBS, dated December 4, 2019, the SBS authorized the transaction, which was made effective on January 2, 2020. At said date, Interseguro received cash for an amount equivalent to S/59,479,000, financial instruments for an equivalent value of S/196,970,000, and recognized the corresponding liabilities for technical reserves determined under IFRS policies. The final value of the portfolio transferred is currently under review by Management of Interseguro and Mapfre.

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 for 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, within 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, as is the interest income of the financial assets that accrue interests classified as available-for-sale held-to-maturity The EIR (and, therefore, the amortized cost of the financial asset) 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 in the consolidated statement of financial position as a positive or negative adjustment of the carrying amount of the financial asset with a 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, the Group calculates the interest income by determining the credit-adjusted EIR at the amortized cost of the asset, as established in Note 30.1(d). 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 within 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 Bank 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 that the Group expects to be entitled to, in exchange for providing its 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 customers, consideration is invoiced and generally due immediately upon satisfaction of a service provided at a specific point in time. For cases in which services are provided over time, consideration is invoiced and generally due at the end of the contract period. 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. Fee income where performance obligations are satisfied over a period 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 are the main income categories 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: For the adoption of IFRS 4 “Insurance Contracts”, the Group decided to continue applying to insurance contracts the existing accounting policies that were applicable 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 were 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 for 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 In the year 2018, the Company adopted these new mortality tables because they reflected recent changes in life expectancy. 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 Adjustment” 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 against 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 within 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 such for the remainder of its term, even if the insurance risk is reduced significantly, 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 insurance. 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, 2019 and 2018, 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 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, 2019 and 2018, 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, 2019 and 2018, Management determined that liabilities were sufficient and therefore, it has not recorded any additional insurance 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 after 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 funds are transferred to the customers while deposits and obligations are recognized when 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 subtracted 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 2019 and 2018, the Group did not originate 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. The Group classifies and measures its derivative and trading portfolio at FVPL as explained in Notes 3.4(f.2) and (f.3). The Group may designate financial instruments at FVPL, 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 FVPL 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 2019 and 2018, the Group only presents derivative financial instruments measured in this way. As detailed in Note 3.2.2, the Group applies IFRS 9 since January 1, 2018. Prior to said date, the Group applied IAS 39, and the criteria for the initial recognition of financial instruments according to this standard are described in Note 3.4(ah).
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 measures 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 outlined 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 it will incorporate such information when assessing newly purchased financial assets going forward. (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 of attention within a lending arrangement are typically the consideration for the time value of money and credit risk. To perform the SPPI assessment, the Group applies judgment 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 FVPL. (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, including, for example, 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 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). (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. FVOCI debt instruments 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 FVOCI 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 FVOCI 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 assets are sold. Dividends are recognized in the consolidated statement of income as income when the right to receive payment has materialized, 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 OCI. Equity instruments at FVOCI are not subject to an 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 interests, 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 issue 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 evaluates whether the liability component has embedded derivatives that must be accounted for separately. (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 FVPL 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 containing 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 financial liabilities at FVPL 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 FVPL due to changes in the Group’s own credit risk. Such changes in fair value are recorded in OCI and do not get reclassified to profit or loss. Interest accrued on assets that must be measured at FVPL is recorded using the contractual interest rate. Dividend income from equity instruments measured at FVPL is recorded in profit or loss as “Interest and similar income”, 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, 2019 and 2018, 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, 2019 and 2018, the Group did not keep any repurchase agreements. As detailed in Note 3.2.2, the Group applies IFRS 9 since January 1, 2018. Prior to said date, the Group applied IAS 39, and the categories for the measurement of financial assets and liabilities according to this standard are described in Note 3.4(ah).
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, it substantially 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 counterparty. • If the modification is such that the instrument would no longer meet the SPPI criterion. Regarding with 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 that 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: • It 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 required remittance to 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 control to be 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. (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.
Impairment of financial assets	(h) Impairment of financial assets - (i) Overview of the ECL principles - The Group records an allowance for expected credit losses for all loans and other debt financial assets not held at FVPL, together with financial guarantee contracts. Equity instruments are not subject to impairment under IFRS 9. The ECL allowance 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 months’ expected credit loss as outlined in (ii). The policies for determining whether there has been a significant increase in credit risk are set out in Note 30.1(d). Both lifetime ECLs and 12 months ECLs are calculated on either an individual basis or a collective basis, depending on the nature of the portfolio. The Group’s policy for grouping financial assets measured on a collective basis is explained in Note 30.1(d). 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 “POCI”, as described below: Stage 1: When loans are first recognized, the Group recognizes an allowance based on 12 months ECLs. Stage 1 also includes loans whose credit risk has improved and the loan has been reclassified from Stage 2. Stage 2: When a loan has shown a significant increase in credit risk since origination, the Group records an allowance for the lifetime ECLs. 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 lifetime ECLs. POCI: Purchased or originated credit impaired (POCI) assets are financial assets that are credit 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 2019 and 2018, 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, 2019 and 2018, 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(f). • Loans; see Notes 3.4(f.1), 6 and 30.1(d). • Due from customers on acceptances. • Other accounts receivable and other assets. For those financial assets other than financial investments and the loan portfolio, Management has estimated the expected credit loss, concluding that it is neither significant nor relevant, given that the maximum period considered for measuring expected credit losses is very small or, even if it implies a longer term, because the main debtor is the Central Reserve Bank of Peru (“BCRP”, by its Spanish acronym) or corresponds to cash in vaults of the Group. (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 outlined 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), 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 presentation date. 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 ECL throughout the life of this asset. The calculation method is similar to that for Stage 1, including the use of multiple scenarios, but ECL 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 ECL 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 FVOCI 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 ECL models, the Group relies on the following macroeconomic variables as forward-looking information inputs as of December 31, 2019 and 2018: • GDP growth • Unemployment rates • Consumer price index • Inflation • Domestic demand • Exchange rate • Purchase capacity • Real compensation 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 collateral. 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 refinance 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 As detailed in Note 3.2.2, the Group applies IFRS 9 since January 1, 2018. Prior to said date, the Group applied IAS 39, and the impairment of financial assets according to this standard is detailed in Note 3.4(ah).
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 - As described in Note 3.2.2, from January, 1, 2019; and after the adoption of IFRS 16, the Group 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 is performing new accounting estimations due to the adoption of IFRS 16 (see Note 3.2.2) 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 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 Until December 31, 2018, leases in which a significant portion of the risks and benefits of the asset were held by the lessor were classified as operating leases. Under this concept, the Group had mainly leased premises used as offices and agencies of the Group’s Subsidiaries. However, as detailed in Note 3.2.2, in the adoption of IFRS 16, 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. (ii) The Group as a lessor – As described in Note 3.2.2, lessor accounting under IFRS 16 is substantially unchanged. The Group will continue to classify leases as either operating or finance leases using similar principles as in IAS 17. As of December 31, 2019 and 2018, 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, 2019 and 2018, 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 recognized when the customer redeems the 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. As of December 31, 2019, 2018 and 2017, the Group has recognized net income of S/8,467,000, S/9,158,000, S/7,884,000, respectively, for transactions carried out on behalf of its customers, which have been recorded in the item “Fee income from financial services, net” of the consolidated statement of income; see Note 20.
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. 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 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” 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 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. 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. 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 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, 2019 and 2018, there have been no contingencies arising from business combinations. A combination of businesses 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 is 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 in 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 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 will be effective since January 1, 2017; 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 deferred tax 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, 2019 and 2018, 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 offering price made in 2007 and 2019, see Note 1(b). 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.2) Reclassification of financial assets and liabilities Until December 31, 2017, reclassifications of available-for-sale held-to-maturity On the other hand, with respect to held-to-maturity
Impairment of the financial assets	(ah.3) Impairment of the financial assets The Group assessed at each date of the consolidated statement of financial position whether there is any objective evidence that a financial asset or a group of financial assets were impaired. There was an impairment if one or more events that have occurred since the initial recognition of the asset (an incurred “loss event”) had an impact on the estimated future cash flows of the financial asset or the group of financial assets that could be reliably estimated. The criteria used for each category of financial assets were as follows: (i) Financial assets carried at amortized cost The Group first assessed whether impairment exists individually for financial assets that were individually significant, or collectively for financial assets that were not individually significant. If the Group determined that no objective evidence of impairment exists for an individually assessed financial asset, whether significant or not, it included the asset in a group of financial assets with similar credit risk characteristics and collectively assessed them for impairment. Assets that were individually assessed for impairment and for which an impairment loss was, or continues to be recognized, are not included in a collective impairment assessment. (ii) Available-for-sale In the case of equity securities, objective evidence would include a significant or prolonged decline in their fair value below cost. Impairment losses on equity securities were not reversed through the consolidated statement of income; increases in their fair value after impairment were directly recognized in the consolidated statement of other comprehensive income. In the case of debt instruments, impairment was assessed based on the same criteria as financial assets carried at amortized cost. The amount recorded for impairment was the cumulative loss measured as the difference between the amortized cost and the current fair value, minus any impairment loss on that investment previously recognized in the consolidated statement of income. (iii) Rescheduled loans (refinanced) Where possible, the Group sought to modify the loans rather than to take possession of the collateral. The rescheduled loans are direct loans in which modifications are made in the time and/or amounts of the original contract due to difficulties in the payment capacity of the client.

(**) The variation of the adjustment of technical reserves is due mainly to aging over time; see Note 14(b). (***) As part of the Private Pension System reform that started in 2013, as regards to the coverage of survival and disability of the pension insurance, the affiliates portfolio was divided into seven parts so that insurance companies manage obligations and rights as a whole. In this way, when an affiliate needs a pension from the pension insurance, the pension will be divided into seven parts and each insurance company will have to assume a corresponding part. This coverage is allocated through a public tender. In December 2016, the call for the “Third Public Tender No. 03/2016” was made to cover the period from January 1, 2017, to December 31, 2018. As result of said process, Interseguro did not win the allocation, but Seguros Sura was awarded a seventh part of this coverage, which is 70 percent reinsured. In November 2018, the call for the “Fourth Public Tender No. 04/2018” was made, to cover the period from January 1, 2019, to December 31, 2020, and as result of this process, the company was not awarded any coverage. (****) In April 2016, the Congress of the Republic of Peru approved the amendment of the SPP 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 “Renta Particular Plus”; Note 10(a), product and raised funds from said product as of December 31, 2019 and 2018, for S/177,842,000 and S/174,632,000, respectively. This allowed to maintain the product portfolio level and the long-term cash fundraising. As of December 31, 2019, retirement premiums amounted to S/3,841,000 (in 2018 and 2017, amounted to S/10,469,000 and S/24,786,000, respectively).

Based on this evaluation, allowances are taken into account for the estimated losses of these loans. As of December 31, 2019 and 2018, 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.
