Introduction, basis of presentation of the consolidated financial statements and other information	1. Introduction, basis of presentation of the consolidated financial statements and other information a) Introduction Banco Santander México, S.A., Institución de Banca Múltiple, Grupo Financiero Santander México (hereinafter, “Banco Santander México”) together with its subsidiaries (hereinafter, the “Bank”) is a subsidiary of Grupo Financiero Santander México, S.A. de C.V. (hereinafter, “the Group”, “Parent” or “Parent company”), which is a subsidiary of Banco Santander, S.A. in Spain (hereinafter, “Banco Santander (Spain)” or “Ultimate Parent”) and holds 96.16% (see Note 3) of its common stock and is regulated by, among others, the Credit Institutions Law ( Ley de Instituciones de Crédito Disposiciones de Carácter General Aplicables a las Instituciones de Crédito The shares of the Bank are listed on the Mexican Stock Exchange and on the New York Stock Exchange as American Depositary Shares. The Bank is subject to the supervision and oversight of the CNBV, the Mexican Central Bank and the United States Securities and Exchange Commission. The Bank’s main activity is to render banking and credit services under the terms of applicable laws, which services include, among others, reception of deposits, granting of loans, trading of securities and the execution of trust contracts. Per legal requirements, Banco Santander México has unlimited liability for the obligations assumed and losses incurred by each of its subsidiaries. The Bank conducts its business through branches and offices located throughout Mexico. The Bank is one of the largest private-sector banks in Mexico. The main office of the Bank is located at Prolongacion Paseo de la Reforma 500, Lomas de Santa Fe, Alvaro Obregon, Ciudad de Mexico, Mexico. The issuance of the consolidated financial statements was authorized by Héctor Blas Grisi Checa, Executive President and Chief Executive Officer (CEO) and Director of the Bank on March 3, 2022. These consolidated financial statements are pending the approval of the Board of Directors and of the ordinary shareholders’ meeting, where they may be modified, based on provisions set forth in the Mexican Corporations Law (Ley General de Sociedades Mercantiles). COVID-19 pandemic Near the end of 2019, a new strain of coronavirus denominated SARS-CoV-2 (hereinafter, “COVID-19”) was first reported. In that period, clusters of cases showing the symptoms of a ‘pneumonia of unknown cause’ were identified in Wuhan, the capital of Central China’s Hubei province. On December 31, 2019, China alerted the World Health Organization (“WHO”) of this new virus and on January 31, 2020, the International Health Regulations Emergency Committee of the WHO declared the outbreak a ‘Public Health Emergency of International Concern’. Since then, COVID-19 has progressively spread around the world, initially in parts of Asia, from where it then moved to Europe, the United States of America and Latin America, among others. On March 11, 2020, the WHO declared the COVID-19 outbreak to be a pandemic. In the United States of America and Latin America, the health crisis began later than in Europe, so its impact was greatest at the end of the first quarter of 2020 and there are no clear signs of recovery during 2020. Viruses change and evolve over time and as they spread between people; just as COVID-19 has. Most of the changes have little or no effect on viruses. However, some changes may have an influence, such as their ease of spread, the disease severity, or the effectiveness of vaccines, drugs for treatment, diagnostics, or other public and social health measures. When changes cause a virus to become substantially different from the original virus, the new virus is said to be a "variant"; Since COVID-19 has spread throughout the world, different variants have emerged in many countries. On November 26, 2021, the WHO declared the "Omicron" variant as a virus of concern, following the advice of the WHO Technical Advisory Group on the Evolution of the Virus. This decision was based on the evidence presented that this variant has several mutations that can have an impact on its behavior, for example, how easily it spreads or the severity of the disease it causes. COVID-19 has significantly affected the world economy. Countries all over the world responded to the COVID-19 pandemic by imposing a variety of measures trying to contain its expansion and impact, including lockdowns on millions of people, the implementation of mass quarantines and other containment measures, travel restrictions, limiting public gatherings and the temporary suspension of most economic activity. The measures adopted led to a notable decrease in global economic activity, disruption of supply chains, falls in production and demand, which resulted in significant Gross Domestic Product (GDP) falls in the most relevant countries, exchange rate volatility, sharp declines and high volatility in the financial and commodities markets worldwide, among others. The Bank’s priority is to protect the health of its employees, customers and shareholders but also to help mitigate the economic and financial impact cause by the health crisis. In this respect, several work streams were activated to find the best possible outcome for customers as well as to preserve the Bank’s strength and solvency while safeguarding the health and safety of its employees, such as: ● Identification of vulnerable customers and sectors that are affected or could be affected by the COVID-19 pandemic. ● Follow-up of customers’ evolution, to ensure that they continue to be provided with the best solution for their situation. This monitoring is accompanied by recovery management activities when necessary. ● Provide to all the employees special safety and protection measures. ● Redefine the way of working to adapt to remote working. ● Ensure the physical and mental well-being of the employees who continued to work in corporate offices, or face to face with customers. These measures included providing masks, gloves and protective screens, as well as the reorganization of physical space to ensure the recommended social distance, combined with strict personal hygiene measures. ● Sent out newsletters including updates on the health crisis ● Financial well-being was also covered, offering various financial support measures to help employees who are experiencing financial difficulties, such as flexible loans or salary advances. ● Training and development programs were adapted to a new online format. In particular, those related to project management, leadership and remote working efficiency. During 2021, the Bank began a program for the return of its employees to the corporate offices, with the objective of achieving a 50% attendance once the COVID-19 pandemic ended. This program was suspended due to the arrival of the Ómicron variant in Mexico in December 2021 and by virtue of safeguarding the health of its employees and business continuity, the Bank reduced attendance in central areas to 25% and canceled face-to-face meetings. Bank’s Management has a reasonable expectation that the Bank has adequate resources to continue in operational existence for the near future. Thus, they continue to adopt the going concern basis of accounting in preparing the consolidated financial statements. b) Basis of presentation The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (hereinafter, “IFRS”) as issued by the International Accounting Standards Board (hereinafter, “IASB”) and IFRIC interpretations, which are developed by the IFRS Interpretations Committee (previously the International Financial Reporting Interpretations Committee or IFRIC) and issued after approval by the IASB. The consolidated financial statements have been prepared on a historical cost basis, except for financial assets and liabilities at fair value through profit or loss (including trading financial derivative instruments), financial assets at fair value through other comprehensive income, hedging financial derivative instruments, non-current assets held for sale and plan assets of defined benefit pension plans, that have been measured at fair value at the end of each reporting period, as explained in the accounting policies below (see Note 2). Historical cost is based on the fair value of the consideration given in exchange for goods and services. The carrying values of recognized assets and liabilities that are designated as hedged items in fair value hedges that would otherwise be carried at amortized cost are adjusted to recognize changes in the fair values attributable to the risks that are being hedged in effective hedge relationships. The consolidated financial statements are presented in Mexican pesos. As used in these consolidated financial statements, the term “billion” means one thousand million (1,000,000,000). The consolidated financial statements filed for Mexican statutory purposes are prepared in accordance with accounting rules and regulations prescribed by the CNBV, as amended, which are hereinafter referred to as Mexican Banking GAAP. Mexican Banking GAAP is composed of Mexican Financial Reporting Standards (“NIF” by its Spanish acronym) as issued by the Mexican Board of Financial Reporting Standards (“CINIF” by its Spanish acronym), which, in turn, are supplemented and modified by specific rules mandated by the CNBV. As of December 31, 2021, the most significant differences between Mexican Banking GAAP and IFRS are: a) Allowance for impairment losses For Mexican Banking GAAP purposes, the allowance for impairment losses and provisions for off-balance sheet risk is determined using prescribed formulas that are based primarily on an expected credit loss model. The expected credit loss model is developed by the CNBV using information compiled from the Mexican lending market as a whole, which may differ from the Bank’s expected credit loss model. In some cases, CNBV can approve the use of internal models to determine the allowance for impairment losses under Mexican Banking GAAP, as an alternative to the regulatory expected credit loss model. b) Effects of inflation Mexican Banking GAAP requires the recognition of the comprehensive effects of inflation when an economic environment becomes inflationary, which, for purposes of Mexican Banking GAAP, is indicated by a three-year cumulative inflation rate of approximately 26% or more. c) Actuarial gains and losses of the pension plan IFRS require the recognition of actuarial gains and losses from the year immediately through other comprehensive income without recycling to profit or loss. Under Mexican Banking GAAP there is an option to recognize actuarial gains and losses from the year, immediately through other comprehensive income as remeasurement of defined benefit obligation and demand their subsequent recycling to profit or loss based on the average remaining life of the pension plan, or to profit or loss of the period in which are determined. d) Deferred employee profit sharing Mexican Banking GAAP requires the recognition of the deferred compulsory employee profit sharing effect based on the temporary differences arising between book and tax value of the assets and liabilities. e) Consolidation of special purpose entities Mexican Banking GAAP does not require the consolidation of those special purpose entities created before January 1, 2009 over which control is exercised. f) Impairment losses of non-current assets held for sale For Mexican Banking GAAP, impairment losses from non-current assets held for sale are determined based on formulas prescribed by the CNBV. g) Leases As a lessee, Mexican Banking GAAP distinguishes leases between two types: ● Operating lease, if the lease does not transfer substantially all the risk and rewards incidental to ownership, the lease payments should be recognized as an expense in the income statement over the lease term on a straight-line basis, unless another systematic basis is more representative of the time pattern of the user's benefit. ● Finance lease, if the lease transfer substantially all the risk and rewards incidental to ownership, at commencement of the lease term, finance leases should be recognized as an asset (decreased by depreciation) and a liability (decreased by payments). h) Finance leases At the beginning of the contract, the lessor will recognize the contractual value (nominal) of the leasing operation within its loan portfolio, against the cash outflow for the acquisition of the underlying asset and the corresponding financial income to be accrued as established by Mexican Banking GAAP. i) Fair value measurements of financial instruments For Mexican Banking GAAP, the fair value measurement of financial derivative instruments non-listed in recognized markets does not consider the counterparty credit risk (Credit Value Adjustment) and the entity’s own credit risk (Debit Value Adjustment). Fair value measurement of financial liabilities at fair value through profit or loss does not consider the entity’s own credit risk for Mexican Banking GAAP. The notes to the consolidated financial statements contain supplementary information to that presented in the consolidated balance sheets, consolidated income statements, consolidated statements of comprehensive income, consolidated statements of changes in total equity and consolidated statements of cash flows. The notes provide, in a clear, relevant, reliable and comparable manner, narrative descriptions and breakdowns of these consolidated financial statements. Resolutions and provisions issued by the CNBV to address the contingency derived from the COVID-19 pandemic During 2020, the CNBV issued some resolutions and provisions to face the contingency derived from the COVID-19 pandemic. In this sense, the CNBV postponed to January 1, 2022 the entry into force of several Mexican Banking GAAP amendments contained in the General Provisions Applicable to Credit Institutions ( Disposiciones de Carácter General Aplicables a las Instituciones de Crédito) New and amended IFRS that are effective for the current year In the current year, the Bank has applied the below amendments to IFRS and International Accounting Standards (hereinafter, “IAS”) issued by the IASB that are mandatorily effective for the accounting period beginning on January 1, 2021. Their adoption has not had any material impact on the disclosures or on the amounts reported in these consolidated financial statements. ● Amendments to IFRS 16 – COVID-19 Related Rent Concessions ● Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 – Interest Rate Benchmark Reform Phase 2 Amendments to IFRS 16 Leases – In response to the COVID-19 pandemic, rent concessions have been granted to lessees. Such concessions might take a variety of forms, including payment holidays and deferral of lease payments. In May 2020, the IASB made an amendment to IFRS 16 that provide practical relief for lessees in accounting for rent concessions. The practical expedient permits a lessee to elect not to assess whether a COVID-19 related rent concession is a lease modification. A lessee that makes this election shall account for any change in lease payments resulting from a COVID-19 related rent concession, the same way it would account for the change as if the change was not a lease modification. Entities applying the practical expedients must disclose this fact, whether the expedient has been applied to all qualifying rent concessions or, if not, information about the contracts to which it has been applied, as well as the amount recognized in profit or loss arising from the rent concessions. The relief was originally limited to reduction in lease payments that were due on or before June 30, 2021. However, in 2021 the IASB subsequently extended this date to June 30, 2022. If a lessee already applied the original practical expedient, it is required to continue to apply it consistently, to all lease contracts with similar characteristics and in similar circumstances, using the subsequent amendment. If a lessee did not apply the original practical expedient to eligible lease concessions, it is prohibited from applying the expedient in the 2021 amendment. However, if a lessee has not yet established an accounting policy on applying (or not) the practical expedient to eligible lease concessions, it can still decide to do so. During 2021, the Bank did not have rent concessions, therefore, this amendment to IFRS 16 is not applicable. Amendments to IFRS 9 Financial Instruments, IAS 39 Financial Instruments: Recognition and Measurement, IFRS 7 Financial Instruments: Disclosures, IFRS 4 Insurance Contracts and IFRS 16 Leases – Interest Rate Benchmark Reform Phase 2 Following the financial crisis, the replacement of benchmark interest rates such as the London Inter-bank Offered Rate (LIBOR) and other Interbank Offered Rates (IBOR), hereinafter the “IBOR Reform”, became a priority for global regulators. Given the pervasive nature of IBOR-based contracts, there are impacts of these changes on financial reporting under IFRS. On July 27, 2017, the Chief Executive of the U.K. Financial Conduct Authority (FCA), which regulates the LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of the LIBOR benchmarks after 2021. The IASB has issued two-phase amendments to provide reliefs from the effects of the IBOR Reform. - Phase 1 - amendments to IFRS 9, IAS 39 and IFRS 7 (IBOR Reform Phase 1) provided temporary reliefs to enable hedge accounting to continue during the period of uncertainty before the replacement of an IBOR with an alternative nearly risk-free interest rate (“RFR”). The IBOR Reform Phase 1 amendments were effective for periods beginning on or after January 1, 2020. - Phase 2 - amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 (IBOR Reform Phase 2) provides temporary reliefs to address the accounting issues, which arise upon the replacement of an IBOR with an RFR. These amendments were published by the IASB on August 27, 2020 and are effective for annual periods beginning on or after January 1, 2021. The Phase 2 amendments provide the following reliefs: When changing the basis for determining contractual cash flows for financial assets and liabilities (including lease liabilities), the reliefs have the effect that the changes, that are necessary as a direct consequence of IBOR reform and which are considered economically equivalent, will not result in an immediate gain or loss in the income statement. The hedge accounting reliefs will allow most IAS 39 or IFRS 9 hedge relationships that are directly affected by IBOR reform to continue. The objective of IBOR Reform Phase 2 amendments is to assist entities in providing useful information about the effects of the transition to an RFR and support preparers in applying the requirements of IFRS when changes are made to contractual cash flows or hedging relationships because of the transition to an RFR. The IBOR Reform Phase 2 amendments affect the following key areas: changes in the basis for determining the contractual cash flows because of IBOR Reform, hedge accounting and disclosures. IBOR Reform Phase 2 amendments provide specific guidance on how to treat financial assets and financial liabilities where the basis for determining the contractual cash flows changes because of IBOR Reform. This can include cases where the contractual terms are amended, cases where the contractual terms are not amended but for example, where the method for calculating the interest rate benchmark is altered, and cases where an existing contractual term is activated such as when a fallback clause is triggered. As a practical expedient, the IBOR Reform Phase 2 amendments require an entity to apply IFRS 9, such that the change in the basis for determining the contractual cash flows is applied prospectively by revising the effective interest rate. This practical expedient only applies when the change in the basis for determining the contractual cash flows is necessary as a direct consequence of IBOR Reform and the new basis for determining the contractual cash flows is economically equivalent to the previous basis (i.e. the basis immediately preceding the change). The IBOR Reform Phase 2 amendments provide a non-exhaustive list of examples of changes that give rise to a new basis for determining the contractual cash flows that is economically equivalent to the previous basis: a) The replacement of an existing interest rate benchmark used to determine the contractual cash flows of a financial asset or financial liability with an RFR or implementation of a reform of an interest rate benchmark by changing the method used to calculate the interest rate benchmark, with the addition of a fixed spread necessary to compensate for the basis difference between the existing interest rate benchmark and the RFR; b) Changes to the reset period, reset dates or the number of days between coupon payment dates in order to implement the reform of an interest rate benchmark; and c) The addition of a fallback provision to the contractual terms of a financial asset or financial liability to enable any of the changes described in a) and b) above to be implemented. Given the similarity of financial liabilities in IFRS 9 and lease liabilities in IFRS 16, the IASB has provided a similar practical expedient in IFRS 16. The practical expedient applies when the interest rate benchmark on which lease payments are based is changed as a direct consequence of IBOR Reform and the change is done on an economically equivalent basis. Like the practical expedient in IFRS 9, the change in the contractual cash flows is applied prospectively. If additional modifications are made to lease contracts that are not required by IBOR Reform, a lessee shall apply the applicable requirements in IFRS 16 to account for all lease modifications made at the same time, including those required by IBOR Reform. An entity may apply the hedge accounting requirements of either IFRS 9 or IAS 39 and therefore both Standards have been amended. The amendments to IFRS 9 and IAS 39 introduce an exception to the existing requirements so that changes in the formal designation and documentation of a hedge accounting relationship, that are needed to reflect the changes required by IBOR Reform, do not result in the discontinuation of hedge accounting or the designation of a new hedging relationship. These changes to the hedge relationship must be made by the end of the reporting period during which a change required by IBOR Reform occurs. The exception applies to the changes to the hedge designation that are limited to one or more of the following changes: a) Designating an RFR (contractually or non-contractually specified) as a hedged risk; b) Amending the description of the hedged item, including the description of the designated portion of the cash flows or fair value being hedged; or c) Amending the description of the hedging instrument; and d) For those applying IAS 39, amending the description of how the entity will assess hedge effectiveness. For the purpose of assessing the retrospective effectiveness of a hedging relationship on a cumulative basis according to IAS 39, an entity may elect to reset the cumulative fair value changes of the hedged item and hedging instrument to zero. This election is made separately for each hedging relationship (i.e. on an individual hedging relationship basis). This election was introduced to minimize the risk that entities would fail the retrospective effectiveness assessment of a hedging relationship when they transition to an RFR. The amendments to IFRS 7 require that an entity provide disclosures that enable a user to understand the nature and extent of risks arising from the IBOR Reform, how the entity is managing those risks, its progress in completing the transition from interest rate benchmarks to RFR and how it is managing the transition. To achieve this objective, an entity is required to disclose: - How it is managing the transition to RFR, its progress at the reporting date and the risks to which it is exposed arising from financial instruments because of the transition; - Disaggregated by significant interest rate benchmark subject to IBOR Reform, quantitative information about financial instruments that have yet to transition to an RFR as at the end of the reporting period, showing separately: non-derivative financial assets, non-derivative financial liabilities and financial derivatives; and - If the IBOR Reform has resulted in changes to an entity’s risk management strategy, a description of those changes. As of December 31, 2021, the IBOR Reform Phase 2 did not have material impact in the consolidated financial statements. The Bank is exposed to the following benchmarks interest rates, which are subject to the IBOR Reform: USD LIBOR and Euro Overnight Index Average (EONIA). The exposures arise on financial derivatives and non-derivative financial assets. In accordance with the exceptions permitted in the Phase 2 amendments, the Bank has elected not to restate comparative financial information for the prior periods to reflect the application of these amendments. Since the Bank had no transactions for which the benchmark rate had been replaced with an alternative benchmark rate, there is no impact on opening balances as a result of retrospective application. The main risks to which the Bank has been exposed as a result of the IBOR Reform are: - Legal risks arising from potential changes required to documentation for new and existing transactions; - Risk management, financial and accounting risks arising from market risk models and from valuation, hedging, discontinuation and recognition of financial instruments linked to benchmark interest rates; - Business risk of a decrease in revenues of products linked to benchmark interest rates that will be replaced; - Pricing risks arising from how changes to benchmark interest rates could impact pricing mechanisms on some instruments; - Operational risks arising from the potential requirement to adapt Information Technology (IT) systems, trade reporting infrastructure and operational processes; - Conduct risks arising from the potential impact of communication with customers and engagement during the transition period, and - Litigation risks regarding our existing products and services, which could adversely impact our profitability. In order to monitor the risks and address the challenges of the transition, Banco Santander (Spain) launched the IBOR Transition Programme in 2019 with the involvement of Bank’s Management. This programme has a group wide scope and reports on a regular basis to Executive Management involving statutory committees. Its main objective is to ensure a smooth operational transition and address any potential customer and conduct related issues that could arise from the IBOR transition. It also aims to ensure that all impacted areas and business units understand the risks associated with the transition in a homogeneous way and can take appropriate measures to mitigate them. This IBOR Transition Programme is aligned with the recommendations, guidance and milestones defined by regulators and working groups of different jurisdictions and is structured around the following areas: Technology and Operations, Legal, Client Outreach, Risk Management and Models, Conduct and Communications and Accounting and Finance. The Bank has also closely monitored the financial markets and the output from the various industry working groups managing the transition to new benchmark interest rates. This includes announcements made by LIBOR regulators, such as the FCA, Alternative Reference Rates Committee (ARRC) and the United States Commodity Futures Trading Commission (CFTC) regarding the transition from LIBOR including British pound sterling (GBP) to the Sterling Overnight Index Average rate (SONIA), United States dollar (USD) LIBOR to the Secured Overnight Financing Rate (SOFR) and EONIA to the Euro short-term rate (€STR). On March 5, 2021, the FCA announced the final dates for the cessation of LIBORs: – On December 31, 2021, the publication of some LIBORs ceased, such as USD LIBOR (1-week and 2-month terms), CHF LIBOR (all terms), GBP LIBOR (overnight, 1-week, 2-month and 12-month terms), JPY LIBOR (overnight, 1-week, 2-month, and 12-month terms) and EUR LIBOR (all terms). – On June 30, 2023, the publication of USD LIBOR (overnight, 12-month and 12-month maturities) will cease and the calculation methodology for USD LIBOR (1-month, 3-month and 6-month maturities) will be reformed and become non-representative. As mentioned above, the breakdown by type of financial asset as of December 31, 2021 of the total of unreformed contracts whose maturity date will be after June 30, 2023 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ USD LIBOR ​ USD LIBOR ​ ​ ​ ​ Total of unreformed contracts ​ ​ Total amount of unreformed contracts ​ ​ ​ ​ ​ ​ ​ ​ ​ Derivatives at fair value (1) ​ ​ 3,690 ​ ​ 9,363 ​ Loans at amortized cost (2) ​ ​ 703 ​ ​ 35,306 ​ Other assets at cost ​ ​ 14 ​ ​ 138 ​ ​ ​ ​ 4,407 ​ ​ 44,807 ​ (1) (2) As of December 31, 2021, the Bank has other financial instruments, including derivatives, loans and other assets referenced to the USD LIBOR with a maturity date prior to June 30, 2023. The Bank has no plans to modify these contracts prior to their contractual maturity; therefore, the Bank does not expect a significant impact arising from IBOR Reform relating to these contracts. Following the recommendations of international and local organizations, as of January 1, 2022, the Bank is no longer offering new loans and derivatives at USD LIBOR, the Bank uses SOFR, in order not to generate more legacy to have to renegotiate in the future. As of December 31, 2021, the Bank has no contractual exposure to EONIA rates. The International Swaps and Derivatives Association (ISDA) reviewed its standardized contracts in the light of the IBOR Reform and amended certain floating-rate options in the 2006 ISDA definitions to include alternative clauses that applied in the permanent discontinuation of certain key IBOR. ISDA published an IBOR fallback supplement to amend the 2006 ISDA definitions and an IBOR fallback protocol to facilitate multilateral amendments to include the amended floating-rate options in financial derivative transactions that were entered into before the date of the supplement. The Bank has adhered to the protocol and intends to monitor whether its counterparties will also adhere. If this plan changes or there are counterparties who will not adhere to the protocol, the Bank will negotiate with them bilaterally about including new fallback clauses. The Bank has no other transactions that are affected by the newly effective requirements. New and revised IFRS in issue but not yet effective At the date of authorization of these consolidated financial statements, the following IFRS had been issued but were not mandatory for annual reporting periods ending on December 31, 2021: ● Amendments to IAS 1 – Classification of Liabilities as Current or Non-current ● Amendments to IAS 1 and IFRS Practice Statement 2 – Disclosure of Accounting Policies ● Amendments to IAS 8 – Definition of Accounting Estimates ● Amendments to IAS 12 – Deferred Tax related to Assets and Liabilities arising from a Single Transaction ● Amendments to IAS 16 – Property, Plant and Equipment: Proceeds before Intended Use ● Amendments to IAS 37 – Onerous Contracts – Cost of Fulfilling a Contract ● Amendments to IFRS 3 – Reference to the Conceptual Framework ● Amendments to IFRS 10 and IAS 28 – Sale or Contribution of Assets between an Investor and its Associate or Joint Venture ● Annual Improvements to IFRS Standards 2018–2020 Cycle Bank’s Management does not expect any material impact from the adoption of these Amendments and Annual Improvements. c) Critical accounting estimates and judgments IFRS requires that Bank’s Management make certain estimates and utilize certain assumptions to determine the valuation of items included in the consolidated financial statements and to make required disclosures. The COVID-19 pandemic resulted in the application of further judgment due to the evolving nature of the pandemic and the limited recent experience of the economic and financial impacts of such event. The COVID-19 pandemic also affected the assumptions and estimation uncertainty associated with the measurement of assets and liabilities. Although the actual results may differ, Bank’s Management believes that the estimates, assumptions and judgments utilized in preparin

Accounting policies
Accounting policies	2. Accounting policies The accounting policies and measurement bases applied in preparing the consolidated financial statements were as follows: a) Foreign currency transactions i. Functional currency The functional currency of all entities comprising the Bank is the Mexican Peso (hereinafter, peso or $). Therefore, all balances and transactions denominated in currencies other than the peso are deemed to be denominated in foreign currency. ii. Foreign currency In preparing the consolidated financial statements, transactions in currencies other than the Bank’s functional currency (foreign currencies) are recognized at the exchange rates prevailing at the dates of the transactions. Monetary items denominated in foreign currencies are retranslated to the functional currency at the rates prevailing at the consolidated balance sheet date. Non-monetary items carried at fair value in foreign currencies are retranslated to the functional currency at the rates prevailing at the date when the fair value was determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated. The Bank performs a large number of foreign currency transactions, mainly in USD. The transactions, assets and liabilities denominated in foreign currencies are translated to pesos based on the exchange rates published by the Mexican Central Bank. The 48-hour exchange rate used as of December 31, 2020 was $19.9087 per one USD and the “day-end” exchange rate used as of December 31, 2021 was $20.5075 per one USD. iii. Recognition of exchange differences The exchange differences arising on the translation of foreign currency balances to the functional currency are recognized at their net amount under Exchange differences (net) in the consolidated income statement, except for exchange differences arising on financial instruments at fair value through profit or loss, which are recognized under Gains/(losses) on financial assets and liabilities (net) in the consolidated income statement without distinguishing them from other changes in fair value and for exchange differences arising on non-monetary items measured at fair value through other comprehensive income, which are recognized under Valuation adjustments in other comprehensive income. b) Basis of consolidation i. Subsidiaries The consolidated financial statements incorporate the financial statements of Banco Santander México and entities (including structured entities) controlled by Banco Santander México together with its subsidiaries. Control is achieved when Banco Santander México has all of the following: ● has power over the investee; ● is exposed, or has rights, to variable returns from its involvement with the investee; and ● has the ability to use its power to affect its returns. Banco Santander México reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. When Banco Santander México has less than a majority of the voting rights of an investee, it has power over the investee when the voting rights are sufficient to give it the practical ability to direct the relevant activities of the investee unilaterally. Banco Santander México considers all relevant facts and circumstances in assessing whether or not Banco Santander México’s voting rights in an investee are sufficient to give it power, including: ● the size of Banco Santander México’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders; ● potential voting rights held by Banco Santander México, other vote holders or other parties; ● rights arising from other contractual arrangements; and ● any additional facts and circumstances that indicate that Banco Santander México has, or does not have, the current ability to direct the relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings. Consolidation of a subsidiary begins when Banco Santander México obtains control over the subsidiary and ceases when Banco Santander México loses control of the subsidiary. Specifically, the results of a subsidiary acquired or disposed of during the year are included in the consolidated income statement and other comprehensive income from the date Banco Santander México gains control until the date when Banco Santander México ceases to control the subsidiary. Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with Banco Santander México’s accounting policies. The financial statements of the subsidiaries are fully consolidated with those of Banco Santander México. Accordingly, all intragroup assets and liabilities, equity, income, expenses and cash flows relating to transactions between the members of the Bank are eliminated on consolidation. Non-controlling interests in subsidiaries are identified separately from the Bank’s equity therein. Those interests of non-controlling shareholders that are present ownership interests entitling their holders to a proportionate share of net assets upon liquidation may initially be measured at fair value or at the non-controlling interests’ proportionate share of the fair value of the acquiree’s identifiable net assets. The choice of measurement is made on an acquisition-by-acquisition basis. Other non-controlling interests are initially measured at fair value. Subsequent to acquisition, the carrying amount of non- controlling interests is the amount of those interests at initial recognition plus the non-controlling interests’ share of subsequent changes in consolidated total equity. The consolidated income statement and each component of other comprehensive income are attributed to the owners of the Bank and to the non-controlling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Bank and to the non-controlling interests even if these results in the non-controlling interests having a deficit balance (see Note 27). The share of third parties of the consolidated total equity is presented under Non-controlling interests in the consolidated balance sheet (see Note 27). Their share of the profit for the year is presented under Profit attributable to non-controlling interests in the consolidated income statement. On acquisition of control of a subsidiary that meets the definition of a business, its assets, liabilities and contingent liabilities are recognized at their acquisition date fair value. Any excess of the acquisition cost, the amount recognized for non-controlling interests of the acquiree and the fair value of the acquirer’s previous held equity interest in the acquiree over the fair values of the identifiable net assets acquired are recognized as goodwill (see Note 16). Negative differences are recognized in the consolidated income statement on the date of acquisition. The results of subsidiaries acquired during the year are included in the consolidated income statement from the date of acquisition to year-end. Similarly, the results of subsidiaries for which control is lost during the year are included in the consolidated income statement from the beginning of the year to the date of disposal. A listing of the subsidiaries included in the consolidated financial statements as of December 31, 2020 and 2021 is shown in Note 49. ii. Investments in associated entities An associate is an entity over which the Bank has significant influence and that is neither a subsidiary nor an interest in a joint venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. The results, assets and liabilities of associated entities are incorporated in the consolidated financial statements using the equity method of accounting, except when the investment, or a portion thereof, is classified as held for sale, in which case it is accounted for in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations An investment in an associate is accounted for using the equity method from the date on which the investee becomes an associate. On acquisition of the investment in an associate, any excess of the cost of the investment over the Bank’s share of the net fair value of the identifiable assets and liabilities of the investee is recognized as goodwill, which is included within the carrying amount of the investment. Any excess of the Bank’s share of the net fair value of the identifiable assets and liabilities over the cost of the investment, after reassessment, is recognized immediately in the consolidated income statement in the period in which the investment is acquired. The requirements of IAS 36 are applied to determine whether it is necessary to recognize any impairment loss with respect to the Bank’s investment in an associate. When necessary, the entire carrying amount of the investment (including goodwill) is tested for impairment in accordance with IAS 36 as a single asset by comparing its recoverable amount (higher of value in use and fair value less costs of disposal) with its carrying amount. Any impairment loss recognized forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized in accordance with IAS 36 to the extent that the recoverable amount of the investment subsequently increases. The Bank discontinues the use of the equity method from the date when the investment ceases to be an associate, or when the investment is classified as held for sale. When the Bank retains an interest in the former associate and the retained interest is a financial asset, the Bank measures the retained interest at fair value at that date and the fair value is regarded as its fair value on initial recognition in accordance with IFRS 9. The difference between the carrying amount of the associate at the date the equity method was discontinued, and the fair value of any retained interest and any proceeds from disposing of a part interest in the associate is included in the determination of the gain or loss on disposal of the associate. In addition, the Bank accounts for all amounts previously recognized in other comprehensive income in relation to that associate on the same basis as would be required if that associate had directly disposed of the related assets or liabilities. Therefore, if a gain or loss previously recognized in other comprehensive income by that associate would be reclassified to the consolidated income statement on the disposal of the related assets or liabilities, the Bank reclassifies the gain or loss from consolidated total equity to the consolidated income statement (as a reclassification adjustment) when the associate is disposed of. When the Bank reduces its ownership interest in an associate but the Bank continues to use the equity method, the Bank reclassifies to the consolidated income statement the proportion of the gain or loss that had previously been recognized in other comprehensive income relating to that reduction in ownership interest if that gain or loss would be reclassified to the consolidated income statement on the disposal of the related assets or liabilities. When a Bank’s subsidiary transacts with an associate or a joint venture of the Bank, profits and losses resulting from the transactions with the associate are recognized in the consolidated financial statements only to the extent of interests in the associate that are not related to the Bank. The Bank applies IFRS 9, including the impairment requirements, to long-term interests in an associate to which the equity method is not applied and which form part of the net investment in the investee. Furthermore, in applying IFRS 9 to long-term interests, the Bank does not take into account adjustments to their carrying amount required by IAS 28 Investments in Associates and Joint Ventures As of December 31, 2020 and 2021, the Bank maintained an investment in an associated entity as detailed in Note 49.a. iii. Structured entities When the Bank incorporates entities, or holds ownership interests therein, to enable its customers to access certain investments, or for the transfer of risks or other purposes (also called structured entities since the voting or similar power is not a key factor in deciding who controls the entity), the Bank determines, using internal criteria and procedures and taking into consideration the applicable legislation, whether control (as defined above) exists and, therefore, whether these entities should be consolidated. These structured entities include securitization special purpose vehicles (SPV) and employee benefit trusts (EBT) established for employee share-based plans, which are consolidated as it is considered that the Bank exercise control over these structured entities. Share-based payments are discussed in Note 42.b, 42.c, 42.d. and 43.b iv. Business combinations Acquisitions of businesses are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred by Banco Santander México, liabilities incurred by Banco Santander México to the former owners of the acquiree and the equity interests issued by the Bank in exchange for control of the acquiree. Acquisition-related costs are recognized in the consolidated income statement as incurred. At the acquisition date, the identifiable assets acquired and the liabilities assumed are recognized at their fair value, except that: ● deferred tax assets or liabilities, and assets or liabilities related to employee benefit arrangements are recognized and measured in accordance with IAS 12 Income Taxes and IAS 19 Employee Benefits , respectively; ● liabilities or equity instruments related to share-based payment arrangements of the acquiree or share-based payment arrangements of Banco Santander México entered into to replace share-based payment arrangements of the acquiree are measured in accordance with IFRS 2 at the acquisition date; and ● assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 are measured in accordance with that Standard. Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree, and the fair value of the acquirer’s previously held equity interest in the acquiree (if any) over the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. If, after reassessment, the net of the acquisition-date amounts of the identifiable assets acquired and liabilities assumed exceeds the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree and the fair value of the acquirer’s previously held interest in the acquiree (if any), the excess is recognized immediately in the consolidated income statement as a bargain purchase gain. When the consideration transferred by Banco Santander México in a business combination includes a contingent consideration arrangement, the contingent consideration is measured at its acquisition-date fair value and included as part of the consideration transferred in a business combination. Changes in fair value of the contingent consideration that qualify as measurement period adjustments are adjusted retrospectively, with corresponding adjustments against goodwill. Measurement period adjustments are adjustments that arise from additional information obtained during the ‘measurement period’ (which cannot exceed one year from the acquisition date) about facts and circumstances that existed at the acquisition date. The subsequent accounting for changes in the fair value of the contingent consideration that do not qualify as ‘measurement period’ adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates and its subsequent settlement is accounted for within equity. Other contingent consideration is remeasured to fair value at subsequent reporting dates with changes in fair value recognized in the consolidated income statement. When a business combination is achieved in stages, the Bank’s interests previously held in the acquired entity are remeasured to its acquisition-date fair value and the resulting gain or loss, if any, is recognized in the consolidated income statement. Amounts arising from interests in the acquiree prior to the acquisition date that have previously been recognized in other comprehensive income are reclassified to the consolidated income statement, where such treatment would be appropriate if that interest were disposed of. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, Banco Santander México reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the amounts recognized at that date. v. Business combinations under common control A common control transaction is a transfer of net assets or an exchange of equity interests between entities under the control of the same parent. A common-control transaction has no effect on the Ultimate Parent’s consolidated financial statements. The net assets are derecognized by the transferring entity and recognized by the receiving entity at their historical carrying amounts. Any difference between the consideration paid or received and the carrying amounts of the net assets is recognized in Accumulated reserves within Shareholders’ equity in the consolidated balance sheet. vi. Changes in Banco Santander México’s ownership interests in existing subsidiaries Changes in Banco Santander México’s ownership interests in subsidiaries that do not result in Banco Santander México losing control over the subsidiaries are accounted for as equity transactions, no gain or loss is recognized in the consolidated income statement and the initially recognized goodwill is not remeasured. The carrying amounts of Banco Santander México’s interests and the non-controlling interests are adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in Accumulated reserves within Shareholders’ equity in the consolidated balance sheet and attributed to owners of Banco Santander México. When Banco Santander México loses control of a subsidiary, a gain or loss is recognized in the consolidated income statement and is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), and liabilities of the subsidiary and any non-controlling interests. All amounts previously recognized in other comprehensive income in relation to that subsidiary are accounted for as if Banco Santander México had directly disposed of the related assets or liabilities of the subsidiary (i.e., reclassified to the consolidated income statement or transferred to another category of equity as specified/permitted by applicable IFRS). The fair value of any investment retained in the former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for subsequent accounting under IFRS 9, when applicable, the cost on initial recognition of an investment in an associate or a joint venture. c) Definitions and classification of financial instruments i. Definitions A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. Financial assets and financial liabilities are recognized when the Bank becomes a party to the contractual provisions of the financial instruments. An equity instrument is a contract that evidences a residual interest in the assets of the issuing entity after deducting all of its liabilities. A financial derivative is a financial instrument or other contract within the scope of IFRS with all three of the following 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 in the case of a non-financial variable that the variable is not specific to a party to the contract (sometimes called the “underlying”); ● it requires no initial net investment or an initial net investment that is smaller than would be required for other types of contracts that would be expected to have a similar response to changes in market factors; and ● it is settled at a future date. Hybrid financial instruments are contracts that simultaneously include a non-derivative host contract together with a financial derivative, known as an embedded derivative, that is not separately transferable and has the effect that some of the cash flows of the hybrid contract vary in a way similar to a stand-alone financial derivative. Compound financial instruments are contracts that simultaneously create for their issuer a financial liability and an equity instrument (such as convertible bonds, which entitle their holders to convert them into equity instruments of the issuer). The following transactions are not treated for accounting purposes as financial instruments: ● Investments in associated entities (see Note 49) ● Rights and obligations under employee benefit plans (see Note 24.c). ● Contracts and obligations relating to employee remuneration based on own equity instruments. ii. Classification of financial assets for measurement purposes Financial assets are initially classified into the various categories used for management and measurement purposes, unless they have to be presented as Non-current assets held for sale or they relate to Cash and balances with the Central Bank or Hedging financial derivatives, which are reported separately. The classification criteria depends on the Bank’s business model for managing the financial assets and the contractual terms of its cash flows. The Bank reclassifies financial assets when, and only when, its business model for managing those financial assets changes. The business model reflects how the Bank manages the financial assets in order to generate cash flows. That is, whether the Bank’s objective is to collect the contractual cash flows from financial assets on specified dates that are solely payments of principal and interest (SPPI), or is to collect both the contractual cash flows and cash flows arising from the sale of financial assets. In determining the appropriate business models for a group of financial assets and assessing the SPPI requirements, the Bank takes into account the following factors: ● How key management personnel are assessed and are reported on the performance of the business model and the financial assets held in the business model. ● The risks that affect the performance of the business model (and the financial assets held in the business model) and, specifically, the way in which these risks are managed. ● How business managers are remunerated. ● The evaluation of the experience on how the cash flows of financial assets were collected. ● The frequency and volume of sales in previous years, as well as expectations of future sales. ● How certain contractual features are considered (i.e., interest rate reset frequency, prepayment commissions, among others) that significantly affect future cash flows. ● The assessment of a compensation paid or received on early termination that could result in cash flows that are not SPPI. ​ Where the business model is to hold financial assets to collect contractual cash flows or to collect both the contractual cash flows and cash flows arising from the sale of financial assets, the Bank assesses whether the financial assets’ cash flows represent SPPI. In making this assessment (SPPI test), the Bank considers whether the contractual cash flows are consistent with a basic lending arrangement. ​ Depending on these factors, the financial asset can be measured at amortized cost, at fair value through other comprehensive income (FVTOCI), or at fair value through profit or loss (FVTPL). IFRS 9 also establishes an option to designate a financial instrument at FVTPL, under certain conditions. ​ Where the contractual terms of the cash flows introduce exposures to risk or volatility that are inconsistent with a basic lending arrangement, the related financial assets are classified and measured at FVTPL. Financial assets that do not meet the criteria for being classified and measured at amortized cost or FVTOCI are classified and measured at FVTPL. Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are SPPI. iii. Classification of financial assets for presentation purposes Financial assets are classified by nature into the following items in the consolidated balance sheet: - Cash and balances with the Central Bank: cash balances and balances receivable including the compulsory deposits with the Central Bank. - Loans and advances to credit institutions: loans of any nature, including deposits and money market transactions, provided to credit institutions. - Loans and advances to customers: debit balances of all loans granted to customers by the Bank. - Debt instruments: bonds and other debt securities that represent a debt obligation for their issuer and that bear interest. - Equity instruments: financial instruments issued by other entities, such as shares, which have the nature of equity instruments for the issuer, other than investments in subsidiaries, associates or jointly controlled entities. - Trading derivatives: fair value in favour of the Bank of financial derivatives, which do not form part of hedge accounting, including embedded derivatives separated from hybrid financial instruments. - Hedging derivatives: fair value of financial derivatives in favour of the Bank, including embedded derivatives separated from hybrid financial instruments, designated as hedging instruments in hedge accounting. iv. Classification of financial liabilities for measurement purposes Financial liabilities are initially classified into the various categories used for management and measurement purposes, unless they relate to hedging financial derivatives, which are reported separately. Financial liabilities are classified for measurement purposes into one of the following categories: - Financial liabilities at fair value through profit or loss: financial liabilities incurred for the purpose of generating a profit in the near term from fluctuations in their prices, financial derivatives not designated as hedging instruments and financial liabilities arising from the outright sale of financial assets acquired under reverse repurchase agreements, securities loans and sales of borrowed securities (short positions). Additionally, financial liabilities are included in this category when such classification provides more relevant information regarding the financial liability, either because this eliminates or significantly reduces recognition or measurement inconsistencies (accounting mismatches) that would otherwise arise from measuring the liabilities or recognizing the gains or losses on them on different bases, or because a group of financial liabilities or financial assets and liabilities is managed and its performance is evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, and information about the group is provided on that basis to the Bank’s key management personnel. - Financial liabilities at amortized cost: financial liabilities, irrespective of their instrumentation and maturity, not included in any of the above-mentioned categories, which arise from the ordinary borrowing activities or financing received. v. Classification of financial liabilities for presentation purposes Financial liabilities are classified by nature into the following items in the consolidated balance sheet: - Deposits: all repayable balances received in cash by the Bank, other than those classified as marketable debt securities and those having the substance of subordinated liabilities. This item also includes cash bonds and cash consignments received, amount of which may be invested without restriction. Deposits are classified based on the type of depositor as follows: - Deposits from the Central Bank: deposits and repurchase agreements of any nature with the Central Bank. - Deposits from credit institutions: deposits of any nature, including credit received, money market transactions and repurchase agreements in the name of credit institutions. - Customer deposits: deposits and repurchase agreements. - Marketable debt securities: bonds and other debt represented by marketable securities, other than those having the substance of subordinated liabilities. - Trading derivatives: fair value of financial derivatives with a liability balance, including embedded derivatives separated from the host contract, which do not form part of hedge accounting. - Short positions: financial liabilities arising from the outright sale of financial assets acquired under reverse repurchase agreements, securities loans and sales of borrowed securities. - Subordinated liabilities: financing received which, for the purposes of payment priority, ranks behind ordinary debt. This category also includes the component that has the consideration of financial liability of compound financial instruments issued by the Bank, which form part of the Bank’s capital management for regulatory purposes, but do not meet the requirements for classification as equity for accounting purposes. - Hedging derivatives: fair value of the Bank’s liability in respect of financial derivatives, including embedded derivatives separated from hybrid financial instruments, designated as qualified hedging instruments in hedge accounting. d) Measurement of financial assets and liabilities and recognition of fair value changes In general, financial assets and liabilities are initially recognized at fair value, which, in the absence of evidence to the contrary, is deemed to be the transaction price. The amount initially recognized for financial instruments not measured at FVTPL is adjusted for transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVTPL are recognized in the consolidated income statement. If the fair value of a financial instrument at initial recognition differs from the transaction price, that financial instrument shall be accounted for at that date as follows: - if that fair value is evidenced by a quoted price in an active market for an identical asset or liability (i.e., a Level 1 input) or based on a valuation technique that uses only data from observable markets, the difference between the fair value at initial recognition and the transaction price shall be recognized as a gain or loss. - in all other cases, adjusted to defer the difference between the fair value at initial recognition and the transaction price. After initial recognition, that deferred difference shall be recognized as a gain or loss only to the extent that it arises from a change in a factor (including time) that market participants would take into account when pricing the asset or liability. Financial assets and liabilities are subsequently measured at each period-end as follows: i. Measurement of financial assets Financial assets measured at fair value The fair value of a financial instrument on a given date is taken to be the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The most objective and common reference for the fair value of a financial instrument is the price that would be paid for it on an active and transparent active market (quoted price or market price).

Basic earnings per share Basic earnings per share are calculated by dividing the profit attributable to the Parent by the weighted average number of shares outstanding during the year, excluding the average number of treasury shares, if any, held in the year (see Note 29.d). Accordingly, basic earnings per share were determined as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2019 ​ ​ 2020 ​ ​ 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Profit attributable to the Parent ​ 20,381 ​ 18,974 ​ 20,801 Profit attributable to the Parent (net of non-controlling interest) ​ ​ 20,381 ​ ​ 18,974 ​ ​ 20,801 Weighted average number of shares outstanding ​ 6,775,455,458 ​ 6,776,640,349 ​ 6,775,682,106 Basic earnings per share (pesos) ​ 3.01 ​ 2.80 ​ 3.07 ​ ii. Diluted earnings per share In calculating diluted earnings per share, the amount of profit attributable to the Parent and the weighted average number of shares issued, excluding the average number of treasury shares, are adjusted to consider all the dilutive effects inherent to potential shares (see Note 29.d). Accordingly, diluted earnings per share were determined as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2019 ​ ​ 2020 ​ ​ 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Profit attributable to the Parent ​ 20,381 ​ 18,974 ​ 20,801 Profit attributable to the Parent (net of non-controlling interest) ​ ​ 20,381 ​ ​ 18,974 ​ ​ 20,801 Weighted average number of shares outstanding ​ 6,775,455,458 ​ 6,776,640,349 ​ 6,775,682,106 Dilutive effect of rights on shares ​ 11,538,899 ​ 10,354,008 ​ 11,312,251 Adjusted number of shares ​ 6,786,994,357 ​ 6,786,994,357 ​ 6,786,994,357 Diluted earnings per share (pesos) ​ 3.00 ​ 2.80 ​ 3.06 ​

Compensation of directors, executive officers and other key management personnel
Compensation of directors, executive officers and other key management personnel	5. Compensation of directors, executive officers and other key management personnel The Bank considers as key management personnel the directors, the executive officers and the members of the audit committee, the corporate practices, the nominating and compensation committee, the comprehensive risk management committee and the remuneration committee. During 2020, the Deputy General Director of Global Corporate Banking, the Deputy General Director of New Businesses, the Vice President of Commercial Banking and the Deputy General Director of Transactions and Digital Banking decided to step down. During 2021, the Deputy General Director of Global Corporate Banking, the Deputy Director of Retail Commercial Banking and the Deputy Director of Operations decided to step down.

Accordingly, only independent directors receive compensation for their duties. Under Mexican law, we are not required to disclose on an individual basis the compensation of our directors, our executive officers and the members of the audit committee, the corporate practices, the nominating and compensation committee, the comprehensive risk management committee and the remuneration committee and we do not otherwise publicly disclose such information. The aggregate compensation paid to independent directors who were members of the audit committee, the corporate practices, the nominating and compensation committee, the comprehensive risk management committee, the remuneration committee and the Board of Directors of the Bank amounted to 21 million pesos during 2019, 23 million pesos during 2020 and 30 million pesos during 2021, paid as attendance fees. b) Remuneration of executive officers The aggregate amount for compensation and benefits to executive officers amounted to 456 million pesos during 2019, 431 million pesos during 2020 and 453 million pesos during 2021. The main benefits paid to the Bank’s executive officers are: salary, Christmas bonus, vacation bonus, holidays, performance bonus and share-based payments. The criteria for granting and paying bonus compensation vary according to the activities performed by the different areas and, therefore, payment of the bonus may vary depending on the department and activities performed by each member. c) Post-employment and other long-term benefits Our executive officers may participate in the same pension and medical expenses plan that is available to the Bank’s employees, but at different contribution percentages to the ones made by the rest of the employees. The total post-employment benefits (including pension plan, medical expenses and life insurance policies) to executive officers amounted to 472 million pesos as of December 31, 2019, 522 million pesos as of December 31, 2020 and 537 million pesos as of December 31, 2021. d) Loans to executive officers The loans granted to executive officers amount to 124 million pesos and 183 million pesos as of December 31, 2020 and 2021, respectively.

Transfers between stages ● The change in the gross carrying amount of Loans and advances to customers – Financial assets at amortized cost that were transferred from Stage 2 to Stage 1 amounting 20,699 million pesos, resulted in a decrease in the allowance for impairment losses of 1,589 million pesos. The main driver of the change is the increase in the “Lifetime PD” used to determine the allowance for impairment losses. ● The change in the gross carrying amount of Loans and advances to customers – Financial assets at amortized cost that were transferred from Stage 3 to Stage 2 amounting 2,013 million pesos, result in a decrease in the allowance for impairment losses of 111 million pesos. The change is not significant because “Lifetime PD” is used to determine the allowance for impairment losses for both stages. ● The change in the gross carrying amount of Loans and advances to customers – Financial assets at amortized cost that were transferred from Stage 3 to Stage 1 amounting 1,102 million pesos, result in a decrease in the allowance for impairment losses of 79 million pesos. The main driver of the change is the use of a twelve-month PD instead of a “Lifetime PD”. ● The gross carrying amount of financial instruments originated in 2021 that amounts to 412,352 million pesos, results in an increase in the allowance for impairment losses of 2,741 million pesos. d) Allowance for impairment losses The changes in the allowance for impairment losses on Loans and advances to customers were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2019 2020 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance as of January 1 ​ ​ (21,516) ​ ​ (21,970) ​ ​ (25,551) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impairment losses on financial assets at amortized cost (*) ​ (21,673) ​ (25,184) ​ (21,949) ​ Impairment losses on financial assets at fair value through other comprehensive income ​ ​ (5) ​ ​ — ​ ​ (7) ​ Write-offs ​ 21,154 ​ 21,590 ​ 26,477 ​ Others ​ 70 ​ ​ 13 ​ (5) ​ Balance at year-end ​ (21,970) ​ (25,551) ​ (21,035) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Of which: ​ ​ ​ ​ By geographical location of risk: ​ ​ ​ ​ Mexico ​ (21,970) ​ (25,551) ​ (21,035) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (*) The amount of Impairment losses on financial assets at amortized cost presented in the consolidated income statement is net of recoveries of loans previously written-off and recovery expenses in the amount of 2,083 million pesos in 2019, 3,453 million pesos in 2020 and 2,720 million pesos in 2021.

Renegotiated loans include restructured or refinancing transactions of performing loans and credit-impaired loans, as contractual terms of a loan may be modified due to not only concerns about the customer’s ability to meet contractual payments, but also for customer retention purposes and other factors not related to current or potential credit deterioration of the customer. A restructured transaction is a transaction with respect to which, for economic or legal reasons relating to current or foreseeable financial difficulties of the customer, the financial terms and conditions are modified in order to facilitate the payment of the debt (principal and interest) because the customer is unable, or might foreseeably become unable, to comply with the aforementioned terms and conditions in due time and form, even if such modification is envisaged in the agreement. A refinancing transaction is a transaction that is granted or used, for reasons relating to current or foreseeable financial difficulties of the customer, to repay one or more of the transactions granted to it, or through which the payments on such transactions are brought fully or partially up to date, in order to enable the customers of the cancelled or refinanced transactions to repay their debt (principal and interest) because they are unable, or might foreseeably become unable, to comply with the conditions thereof in due time and form.

The types of terms that are typically renegotiated include: (a) modifications to the contractual terms of loans, such as payment terms, interest rates and currency, or (b) modifications to the guarantees that cover the loans. See Note 48 b) 4.7 Recovery and collections management for additional information regarding renegotiated loans. g) Modification on financial instruments in the context of COVID-19 pandemic During 2020, the relief measures contained in the Support Program resulted in a modification to the contractual terms of the loans subject to the Support Program, that did not result in derecognition of the financial assets under IFRS 9. The breakdown of Gains/(losses) on modification of financial assets (net) recognized in the consolidated income statement as of December 31, 2020 is as follows: ​ ​ ​ ​ ​ ​ ​ 2020 ​ ​ ​ ​ ​ Commercial, financial and industrial loans ​ (605) ​ Mortgage loans ​ ​ (224) ​ Installment loans to individuals - ​ ​ ​ ​ Non-revolving consumer loans ​ ​ (914) ​ ​ ​ (1,743) ​ ​ h) Maximum exposure to credit risk and credit quality information Maximum exposure to credit risk The tables below represent the Bank’s maximum exposure to credit risk by class of financial instrument (except for hedging financial derivatives) and the respective collateral and other credit enhancements mitigating credit risk for these classes of financial instruments. The maximum exposure to credit risk includes the carrying amounts of financial instruments recognized in the consolidated balance sheet subject to credit risk and the nominal amounts for off-balance sheet commitments. Where available, collaterals are presented at fair value; for other collaterals, such as real estate and other assets, best estimates of fair value are used. Other credit enhancements such as guarantees are included at their nominal amounts. Collateral or guarantees are credit enhancements in the form of an asset or third-party obligation that serve to mitigate the inherent risk of credit loss in an exposure, by either substituting the borrower default risk or improving recoveries in the event of a default. The Bank’s collateral or guarantees are contractual and are typically classified as follows: ● Financial and other collateral, which enables the Bank to recover all or part of the outstanding exposure by liquidating the collateral asset provided in cases where the borrower is unable or unwilling to fulfill its primary obligations. Cash collateral, securities (debt or equity instruments), collection rights, inventory, equipment and real estate are included in this category: - Cash collateral received - cash collateral requested from financial and corporate customers to secure the payments in OTC financial derivatives transactions. - Collateralized by securities - collateral to secure the payments in repurchase agreements and reverse repurchase agreements transactions. - Collection rights - highly liquid and realizable guarantees, which are mainly comprised of standby letters and pledges on funds and securities. - Real estate. ● Guarantees, which complement the customer’s ability to fulfill its obligation under the legal contract and, as such, is provided by third parties in the form of individual guarantee by endorsement or co-signers, where individuals or companies act as guarantors of the loan transaction. Collaterals and other credit enhancements related to the commercial loan portfolio are subject to at least an annual review. In the case of guarantees, the guarantor’s ability to perform under the guarantee contract is reviewed through an analysis of the financial position of the customer and the guarantor. There are cases where the Bank has attempted to seek recovery through the execution of a third-party guarantee and has been denied such recovery. Please see Note 2.g for an explanation of how the credit ratings of guarantors affect our allowance for impairment losses. For the retail loan portfolio, a review of its collaterals and other credit enhancements is performed on a periodic basis depending on the history of the payment performance of the borrower. For the real estate collaterals, appraisals are obtained as of the date of origination of the loans and when the loan is classified as impaired.

Credit quality information For commercial loans (except small and medium-sized enterprises or SME) and public sector loans, in order to achieve equivalent internal ratings in the different models available and to make them comparable with the external ratings of rating agencies, the Bank has developed a master rating scale. The equivalence is established through the PD associated with each rating. “Internally calibrated PDs” are compared against the default rates associated with the external ratings, which are published periodically by rating agencies. The internal rating scale and mapping with external ratings are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equivalence with ​ Standard & ​ Internal Rating ​ Poor’s ​ Moody’s ​ ​ ​ ​ ​ ​ ​ 9.3 ​ Aaa ​ AAA 9.2 ​ Aa1 ​ AA+ 9.0 ​ Aa2 ​ AA 8.6 ​ Aa3 ​ AA- 8.1 ​ A1 ​ A+ 7.7 ​ A2 ​ A 7.3 ​ A3 ​ A- 6.7 ​ Baa1 ​ BBB+ 6.1 ​ Baa2 ​ BBB 5.6 ​ Baa3 ​ BBB- 5.0 ​ Ba1 ​ BB+ 4.4 ​ Ba2 ​ BB 3.9 ​ Ba3 ​ BB- 3.3 ​ B1 ​ B+ 2.7 ​ B2 ​ B 2.2 ​ B3 ​ B- 1.6 ​ Caa1 ​ CCC 1.0 ​ Ca ​ CC ​ For commercial loans to small and medium-sized enterprises (SME), mortgage loans and installment loans to individuals (revolving credit card consumer loans and non-revolving consumer loans), expected credit losses are calculated using statistical methods without considering internal ratings. However, based on criteria set forth by the CNBV and a combination of internal scorecards, customer’s financial information and qualitative criteria, ratings are assigned as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ Rating Equivalence ​ ​ ​ ​ A-1 ​ Minimum Risk (Solid) A-2 ​ Low Risk (Outstanding) B-1 ​ Normal Risk (Good) B-2 ​ Normal Risk B-3 ​ Satisfactory C-1 ​ Normal Risk (Adequate) C-2 ​ Medium Risk (Weak) D ​ High Risk (Poor) E ​ Probable Loss ​ Credit quality information by rating category The tables below represent the classification by rating category of commercial loans (except SME) and public sector loans and their related guarantees and loan commitments not recognized in the consolidated balance sheet: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 12/31/2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Not ​ ​ Rating Category 9.3 9.2 9.0 8.5 8.0 7.5 7.0 6.5 6.0 5.5 5.0 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 Rated Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial loans (

Hedging derivatives
Hedging derivatives	12. Hedging derivatives The Bank, as part of its financial risk management strategy and for reducing mismatches in the accounting treatment of its transactions, enters into interest rate and foreign currency hedging financial derivatives, depending on the nature of the hedged risk. In line with its objective, the Bank classifies its hedges into the following categories: - Cash flow hedges: hedging the exposure to variability in cash flows associated with an asset, liability or highly probable forecast transaction. - Fair value hedges: hedging the exposure to changes in the fair value of assets or liabilities attributable to an identified hedged risk. As mentioned in Note 2, the Bank has been applying hedge accounting under IAS 39. The Bank’s risk management strategy has not changed due to the COVID-19 pandemic and determined that the timing of forecast transactions has no changed and the cash flows are truly expected to occur. a) Breakdown The breakdown by type of hedge of the financial derivatives qualifying for hedge accounting is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 12/31/2020 ​ ​ 12/31/2021 ​ Assets Liabilities Assets Liabilities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair value hedges ​ 11 ​ 16,604 ​ 1,468 ​ 7,018 Cash flow hedges ​ 8,295 ​ 2,474 ​ 9,780 ​ 1,144 ​ ​ 8,306 ​ 19,078 ​ 11,248 ​ 8,162 ​ b) Quantitative information Fair value hedges As of December 31, 2020, the hedging financial derivative positions are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nominal ​ ​ ​ ​ ​ ​ ​ ​ (Million in ​ ​ ​ ​ ​ ​ ​ ​ ​ Nominal ​ ​ Transaction ​ ​ Transaction ​ ​ ​ ​ ​ ​ (Million Pesos) ​ ​ Currency) ​ ​ Currency ​ ​ Hedged Item and Risk Hedged ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ IRS ​ 2,333 ​ 2,333 ​ Peso ​ Loans - Interest rate risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ IRS ​ 1,000 ​ 1,000 ​ Peso ​ Promissory notes - Interest rate risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ IRS ​ ​ 47,047 ​ ​ 47,047 ​ ​ Peso ​ ​ M Bonds - Interest rate risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 265 ​ 13 ​ Euro ​ Loans - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 16 ​ 1 ​ USD ​ Loans - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 23,431 ​ 1,089 ​ Euro ​ UMS - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 7,824 ​ 398 ​ USD ​ UMS - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 1,492 ​ 58 ​ Pound sterling ​ UMS - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 1,895 ​ 405 ​ UDI ​ UDIBONDS - Interest rate and inflation risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, 2021, the hedging financial derivative positions are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nominal ​ ​ ​ ​ ​ ​ ​ ​ (Million in ​ ​ ​ ​ ​ ​ ​ ​ ​ Nominal ​ ​ Transaction ​ ​ Transaction ​ ​ ​ ​ ​ ​ (Million Pesos) ​ ​ Currency) ​ ​ Currency ​ ​ Hedged Item and Risk Hedged ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ IRS ​ 1,867 ​ 1,867 ​ Peso ​ Loans - Interest rate risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ IRS ​ 47,047 ​ 47,047 ​ Peso ​ M Bonds - Interest rate risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 4 ​ 1 ​ USD ​ Loans - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 17,744 ​ 819 ​ Euro ​ UMS - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 7,824 ​ 398 ​ USD ​ UMS - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 1,492 ​ 58 ​ Pound sterling ​ UMS - Interest rate and foreign exchange risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CCS ​ 1,895 ​ 405 ​ UDI ​ UDIBONDS - Interest rate and inflation risk ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The fair value hedges carried out by the Bank are extended in certain cases up to the year 2034.

Intangible assets - Goodwill	16. Intangible assets – Goodwill As of December 31, 2020 and 2021, Goodwill amounted to 1,734 million pesos. a) Impairment test The main assumptions used in the calculation of the impairment of Goodwill are as follows: ​ ​ ​ ​ ​ ​ Hypotheses ​ ​ ​ ​ Basis of valuation ​ Value in use: discounted cash flows Period of projection of cash flows(1) ​ 10 years Perpetual cash flow ​ (2) Discount rate(6) ​ 8.72% Of which: ​ Cost of Equity(3) ​ 14.21% Cost of Debt(4) ​ 5.81% Equity Structure(5) ​ 35% Equity / 65% Debt (1) The period of projections of cash flows are prepared using internal budgets and growth plans of Banks’ Management, based on historical data, market expectations and conditions such as industry growth and inflation. (2) The perpetual cash flow has been calculated based on the following formula over the last cash flow estimated [D*(1+g)//i-g)]*(1+i) ˄ -n, where: ● D = Last estimated cash flow, ● g = Perpetual growth (0%), ● i = Discount rate, and ● n= Number of year of last estimated cash flow. (3) The Cost of Equity has been calculated based on the following formula Rf+(ß*Pr), where: ● Rf = Risk free rate (7.96%), ● β = Beta (1.07), and ● Pr = Equity Risk Premium (5.84%). (4) The Cost of Debt has been calculated based on the actual pretax financing cost of the Bank. (5) The Equity Structure has been calculated based on the following formula: Equity/(Total Liability+Equity). The Debt Structure has been calculated based on the following formula: Debt/(Total Liability+Equity). (6) The Discount rate has been calculated based on the following formula: (Cost of Equity*Equity Structure) + (Cost of Debt*Debt Structure). The assumptions used in performing the interim impairment test were updated to reflect the best approximation of market behavior. As of December 2020 and 2021, the recoverable value of the CGU is higher than its book value. Based on the foregoing, and in accordance with the estimates, projections and measurements available to the Bank’s Management in 2019, 2020 and 2021, the Bank has not recognized any impairment losses on Goodwill.

Subordinated Additional Tier I Capital Notes are convertible into common Series F shares and are callable (either fully or partially) at par in cash at the first call date (January 20, 2022) and subsequently every interest payment date. Interests are non-cumulative and fully discretionary. Some trigger events originate the cancellation of interest payment. Additional characteristics of the Subordinated Additional Tier I Capital Notes are as follows: ● Automatically convertible into common shares when the Common Equity Tier I (CET I) or Basic Capital is equal to or below 5.125% (among other trigger events) at Conversion price (defined below). ● Conversion price: The conversion price shall be, if the common shares are: i. traded on the Mexican Stock Exchange, the higher of: a. the weighted average volume of the ordinary shares closing price on the Mexican Stock Exchange for the thirty consecutive business days immediately preceding the conversion date, with each closing price for the thirty consecutive business days being converted from pesos into USD at the then prevailing exchange rate; or; b. the floor price of 20.30 pesos converted into USD at the then-prevailing exchange rate. ii. not traded on the Mexican Stock Exchange, the floor price of 20.30 pesos converted into USD at the then-prevailing exchange rate. ● Subordinated Additional Tier I Capital Notes will accrue interest on an annual interest rate of 8.5% (subject to not being called in advance at the first call date or if the automatic conversion occurs), which will reset every five years considering the current five-year US Government Treasury Bills interest rate plus the original credit spread. Interest payments will be recognized as a reduction of Accumulated reserves within Shareholders’ equity in the consolidated balance sheet. ● Fully callable in advance if the Subordinated Additional Tier I Capital Notes: i) fail to be considered as Fundamental Basic Capital, ii) interest is considered non-deductible for tax purposes, or iii) the applicable withholding tax increases. ● Any call in advance must be authorized by the Central Bank. These Subordinated Additional Tier I Capital Notes are accounted for as a compound instrument with both liability and equity components (that arises from the contingent settlement provision and from the right of the holders to receive discretional interest payments, respectively). The payment of discretionary interest is recorded in Accumulated reserves within Shareholders’ equity in the consolidated balance sheet. The liability component is recognized at the par value of the Subordinated Additional Tier I Capital Notes and is then deducted from the fair value of the compound financial instrument as a whole to arrive at the value of the equity component. A zero balance to the equity component is assigned, since there is an obligation to pay the full redemption amount and cannot avoid settlement in cash or another financial asset for the full redemption amount. In addition, an embedded derivative arises from the call option features on the Subordinated Additional Tier I Capital Notes within five years subsequent to the issuance date and on every interest payment date thereafter. This call option is deemed to be closely related to the Subordinated Additional Tier I Capital Notes and is not accounted for separately. 2018 Tier II Subordinated Notes On October 1, 2018, Banco Santander México issued debt securities denominated as Tier II Subordinated Notes in the amount of USD 1,300 million equivalent to 1,300,000 securities with a nominal value of USD 1,000 each with a ten-year maturity (October 30, 2028) and with an option to be prepaid in year five The main features of this issue are as follows: a) If notes are not redeemed in year five, the interest rate for the second five-year period shall be based on the interest rate on US five-year Treasury Notes in effect at that moment plus the spread defined in the offering memorandum. b) Loss absorption mechanism through a write-down of the issue being the trigger event a computation of Banco Santander México’s Basic Capital index of 4.5%. c) Partial write-down until Banco Santander México achieves a Basic Capital index of 7.0%. d) When Banco Santander México computes a Basic Capital index of 8.0%: - Possible deferral of principal, interest or other remedies determined by the CNBV. - Possible write-down due to breach of remediation. - Possible early prepayment in an event of non-deductibility of interest or by the increase in the applicable withholding tax led by the consideration of the notes issued as Tier II Complementary Capital. With the proceeds obtained from the issue of these Tier II Subordinated Notes, Banco Santander México redeemed in advance USD 1,223 million of the Tier II Subordinated Capital Notes issued on December 27, 2013. 2021 Subordinated Additional Tier I Capital Notes On September 15, 2021, Banco Santander México issued perpetual subordinated non-preferred contingent convertible additional Tier I Capital Notes for USD 700 million with no fixed maturity or fixed redemption date, at an annual variable interest rate, which will be recalculated every 5 years based on the yield of the Treasury Notes of the United States of North America (US Treasury Notes) with a term of 5 years that is in force at that time plus the spread defined in the placement supplement. Additional characteristics of the Subordinated Additional Tier I Capital Notes are as follows: ● The initial annual interest rate at the time of issuance was 4.625%. ● Conversion price: The conversion price shall be, if the common shares are: i. a. thirty thirty b. ii. ● Banco Santander México may prepay the Additional Tier I Capital Notes after five years , prior compliance with the following: - Authorization is obtained from Banco de México to amortize the Subordinated Additional Tier I Capital Notes early; - If Banco Santander México maintains its total capitalization ratio equal to or greater than that required by the CNBV plus the corresponding capital supplements; or if - Replace the instrument with other financial instruments. d) Reconciliation of liabilities arising from financing activities The table below details changes in the Bank’s liabilities arising from financing activities, including both cash and non-cash changes. Liabilities arising from financing activities are those for which cash flows were, or future cash flows will be, classified in the consolidated statement of cash flows as cash flows from financing activities. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-cash changes ​ ​ ​ ​ ​ ​ January 1, 2020 ​ ​ Cash flows ​ ​ Accrued ​ ​ Transaction ​ ​ Foreign exchange ​ ​ December 31, 2020 Type ​ ​ ​ ​ ​ ​ ​ interest ​ ​ costs ​ ​ movements ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Subordinated Additional Tier I Capital Notes ​ 9,420 ​ — ​ — ​ ​ 6 ​ ​ 522 ​ ​ 9,948 Tier II Subordinated Capital Notes ​ 24,847 ​ (1,765) ​ 1,669 ​ ​ 8 ​ ​ 1,475 ​ 26,234 Balances at ​ 34,267 ​ (1,765) ​ 1,669 ​ ​ 14 ​ ​ 1,997 ​ 36,182 ​ As of December 31, 2020, the Bank paid 964 million pesos related to interests on the Subordinated Additional Tier I Capital Notes, which were recognized against Accumulated reserves within Shareholders’ equity in the consolidated balance sheet. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-cash changes ​ ​ ​ ​ ​ ​ January 1, 2021 ​ ​ Cash flows ​ ​ Accrued ​ ​ Transaction ​ ​ Foreign exchange ​ ​ December 31, 2021 Type ​ ​ ​ ​ ​ ​ ​ interest ​ ​ costs ​ ​ movements ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Subordinated Additional Tier I Capital Notes ​ ​ — ​ ​ 13,930 ​ — ​ ​ — ​ ​ 425 ​ ​ 14,355 Subordinated Additional Tier I Capital Notes ​ 9,948 ​ — ​ — ​ ​ 6 ​ ​ 300 ​ ​ 10,254 Tier II Subordinated Capital Notes ​ 26,234 ​ (1,586) ​ 1,576 ​ ​ 10 ​ ​ 800 ​ 27,034 Balances at ​ 36,182 ​ 12,344 ​ 1,576 ​ ​ 16 ​ ​ 1,525 ​ 51,643 ​ As of December 31, 2021, the Bank paid 1,073 million pesos related to interests on the Subordinated Additional Tier I Capital Notes, which were recognized against Accumulated reserves within Shareholders’ equity in the consolidated balance sheet.

Dividends paid by Banco Santander México to Mexican resident individuals and foreign residents in 2019, 2020 and 2021 are not subject to the 10%additional withholding tax as such dividends were paid from profits obtained prior to 2014. Legal reserve Banco Santander México is subject to the legal reserve provision whereby at least 10% of net profits each year must be allocated and transferred to a capital reserve fund until reaching the equivalent of 100% of the paid-in share capital. Regarding Banco Santander México’s subsidiaries, the legal reserve provision requires the creation of a legal reserve equal to 5% of net profits until reaching 20% of paid-in share capital. The legal reserve cannot be distributed to the shareholders during the existence of the aforementioned entities, except in the form of a stock dividend. As of December 31, 2020 and 2021, Banco Santander México and its subsidiaries comply with the percentage of legal reserve required.

Minimum capital requirements
Minimum capital requirements	30. Minimum capital requirements Banco Santander México’s risk-weighted assets and capitalization ratios are calculated in accordance with Mexican Banking GAAP. The management of capital is performed at regulatory and economic levels. As established in the General Provisions Applicable to Credit Institutions ( Disposiciones de Carácter General Aplicables a las Instituciones de Crédito Net Capital Net capital is divided into two parts: Basic Capital and Complementary Capital. Additionally, Basic Capital is divided into two portions: Fundamental Basic Capital and Non-Fundamental Basic Capital. Basic Capital (Tier I Capital) is the sum of Fundamental Basic Capital and Non-Fundamental Basic Capital. - Fundamental Basic Capital is composed mainly of shareholders’ equity plus other equity instruments, less, among other deductions: stock investments on financial institutions, organizational expenses, other intangibles assets, excess of deferred tax assets derived from tax losses of Tier I Capital and excess of deferred income taxes from temporary differences that exceed the 10% of Tier I Capital. - Non-Fundamental Basic Capital is composed mainly of a bank’s equity instruments, which are not included as Fundamental Basic Capital according to the current legislation. - Complementary Capital (Tier II Capital) is composed mainly of a bank’s equity instruments, which are not included as Basic Capital according to the current legislation, and the positive difference resulting from subtracting to the total permitted reserves, the total expected losses, up to an amount that does not exceed 0.6% of the assets subject to credit risk. Assets Subject to Credit Risk Deposits, securities, loans and advances, reverse repurchase agreements, swaps, forward contracts, securities loans, options, certain financial derivative instruments and all other bank transactions exposed to credit risk in accordance with established regulations are classified in their respective risk groups and the weight factors stipulated for each group are applied, ranging from zero up to 150%, depending on the counterparty and scores determined by the ratings agencies accredited by the CNBV or by Banco Santander México in the event it is an authorized institution for the use of internal models. Counterparty risk is calculated by incorporating an add-on and calculating a CVA for OTC financial derivatives transactions. Since September 2021, the CNBV has published new credit risk weights applicable to new loans originated since September 1 that belong to retail (mortgages and consumer) and SMEs portfolios. Assets Subject to Market Risk In interest bearing transactions, the capital requirement is calculated by determining the residual term of the financial asset or financial liability and by applying the corresponding Market Risk Charge Coefficient based on the residual term and currency of the financial asset or financial liability. For those transactions, whose return is based on changes in the price of a share, basket of shares or market index, a 22.23% of General Market Risk Charge Coefficient is applied to the net position, to which additional specific market risk requirements are added for long net positions and short net positions by 8%. For foreign currency positions, a 12% Market Risk Charge Coefficient is applied on the higher of the sum of the long net position or short net position. For transactions linked to Mexican inflation and denominated in UDI, a capital requirement is calculated by applying a Market Risk Charge Coefficient of 1.25% over the increase of the INPC (calculated as the average of the previous twelve months) to the absolute value of the total net position. For options and warrants, a Vega (variations on volatility) and Gamma (variations on the subjacent) capital requirement is calculated by applying the rules defined on Article 2 bis 109 of the General Provisions Applicable to Credit Institutions ( Disposiciones de Carácter General Aplicables a las Instituciones de Crédito For transactions linked to the annual minimum salary growth, a capital requirement is calculated by applying a Market Risk Charge Coefficient of 1.25% over the increase of the annual minimum salary growth (calculated as the average of the current month and the previous eleven months) to the absolute value of the total net position. The equivalent assets for market risk are determined by multiplying by 12.5, the sum of the capital requirements of all the transactions described above. Assets Subject to Operational Risk Since November 2016, Banco Santander México uses the Alternative Standardized Approach under Basel II standards to calculate the assets subject to operational risk. This method consists first of dividing the business into eight lines. For six of them, the capital requirement is calculated multiplying a “Beta” factor for the average net revenues for the thirty-six months prior to the month being calculated and for the two remaining (Retail and Commercial), the capital requirement is calculated by determining the average net balance for the thirty-six months prior to the month being calculated multiplied for a “Beta” factor and for 3.5. The equivalent assets for operational risk are determined by multiplying the capital requirement by 12.5. Business Indicator Method On November 19, 2020, the CNBV published the methodology of the Business Indicator Method ( Método del Indicador de Negocio The minimum capital requirements calculated in accordance with Mexican Banking GAAP for Banco Santander México is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 12/31/2020 12/31/2021 ​ ​ ​ ​ ​ ​ ​ ​ Computable capital: ​ 151,458 ​ 168,616 ​ Core capital ​ 158,786 ​ 165,626 ​ Supplementary capital ​ 27,203 ​ 27,928 ​ Deductible items ​ (44,479) ​ (49,547) ​ Subordinated Additional Tier I Capital Notes (see Note 22.c) ​ 9,948 ​ 24,609 ​ ​ ​ ​ ​ ​ ​ ​ ​ Capital requirements: ​ 61,127 ​ 62,564 ​ Market risk ​ 15,398 ​ 15,354 ​ Credit risk ​ 43,215 ​ 41,416 ​ Operational risk ​ 5,133 ​ 5,794 ​ ​ ​ ​ ​ ​ ​ ​ ​ Excess of capital requirements ​ 90,331 ​ 106,052 ​ Risk-weighted assets ​ 796,836 ​ 782,050 ​ ​ As of December 31, 2020 and 2021, in accordance with the capitalization requirements applicable to full service banks, Banco Santander México has the following capitalization ratios, which exceed the minimum legal capital required by the CNBV. The capital ratios included in this table are in accordance to the data published by the CNBV. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 12/31/2020 12/31/2021 ​ ​ ​ ​ ​ ​ ​ ​ Net Capital / Required Capital ​ 2.38 ​ 2.70 ​ Minimum capital requirements ​ Not applicable ​ Not applicable ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic Fundamental Capital / Assets subject to Credit, Market and Operating Risk ​ 14.35 % 14.84 % Minimum capital requirements ​ 8.20 % 8.20 % ​ ​ ​ ​ ​ ​ ​ ​ Basic Capital / Assets subject to Credit, Market and Operating Risk ​ 15.59 % 17.99 % Minimum capital requirements ​ 9.70 % 9.70 % ​ ​ ​ ​ ​ ​ ​ ​ Net Capital / Assets subject to Credit Risk ​ 28.04 % 32.57 % Minimum capital requirements ​ Not applicable ​ Not applicable ​ ​ ​ ​ ​ ​ ​ ​ ​ Net Capital / Assets subject to Credit, Market and Operating Risk ​ 19.01 % 21.56 % ​ ​ ​ ​ ​ ​ ​ ​ Minimum capital requirements ​ 11.70 % 11.70 % ​ Resolutions and provisions issued by the CNBV to address the COVID-19 pandemic On April 8, 2020, the CNBV issued some resolutions and provisions to face the contingency derived from the COVID-19 pandemic. In this sense, the CNBV approved temporary amendments to the General Provisions Applicable to Credit Institutions ( Disposiciones de Carácter General Aplicables a las Instituciones de Crédito The CNBV determined to grant temporary regulatory support measures regarding capitalization, between April 1, 2020 and March 31, 2021, in order to allow banks to use the capital conservation supplement (Capital buffer) without impairing its minimum solvency. The Bank decided not to apply the optional regulatory support measure. In the Provisions Applicable to Credit Institutions ( Disposiciones de Carácter General Aplicables a las Instituciones de Crédito Sistema de Alertas Tempranas Regulatory support measures consist, among others, on the fact that banks will not have to submit the capital conservation plan for CNBV’s approval when using capital conservation supplements, if such supplement is consumed in a maximum of 50%. The CNBV must be informed of the causes that originated the use of the supplement; otherwise, authorization must be requested from the CNBV so that, in justified cases, the banks can increase the amounts disposed of the loans granted to related persons. On June 18, 2021, the CNBV published the TLAC rule for Mexico. The TLAC standard issued by the Financial Stability Board requires global systemically important banks (G-SIB) to have financial instruments available during resolution to absorb losses and enable them to be recapitalized to continue performing their critical functions while the resolution process is ongoing. The objective is to have an orderly resolution by making debt/equity holders absorb losses (enabling a ‘bail-in’), instead of using public funds (conducting a ‘bailout’). The local implementation considers a capital add-on over the total capital ratio of the maximum of 6.5% of RWAs and 3.75% of the leverage ratio denominator. The TLAC requirement can only be met with capital instruments. This requirement will have a phase-in period, which starts on December 2022 with a 25% of the add-on and will increase 25% each year to reach a 100% of the add-on on December 2025.

A significant portion of the guarantees and loan commitments will expire without any payment obligation materializing for the Bank and, therefore, the aggregate balance of these commitments cannot be considered an actual future need for financing or liquidity to be provided by the Bank to third parties.

Such collateral is contractually agreed to with each of the counterparties. Currently, debt instruments, mainly government bonds, are posted as collateral for transactions with domestic financial entities. Cash deposits are used for transactions with foreign financial entities and institutional customers. The nominal and/or contractual amounts of the financial derivatives contracts traded by the Bank do not reflect the actual risk assumed by the Bank since the net position in these financial instruments is the result of offsetting and/or combining them. The net position is used by the Bank to hedge interest rates, underlying asset prices or foreign currency risk and to assume directional exposure to risk factors limited by the Bank’s risk appetite. The results of these financial instruments are recognized in Gains/(losses) on financial assets and liabilities (net) in the consolidated income statement. If their purpose is to hedge other exposures, they increase or offset, as appropriate, the gains or losses on the hedged investments (see Note 12). The Bank manages the credit risk exposure of these contracts through setting credit lines, establishing netting arrangements with its main counterparties and by receiving assets as collateral (see Note 2.f). The cumulative credit risk exposure is measured in terms of Equivalent Credit Risk (hereinafter, “ECR”). ECR is composed of the current exposure of the contract (at fair value in the case of financial derivatives) and the Potential Future Exposure (hereinafter, “PFE”) which is defined as the maximum expected credit risk exposure over a specified period of time calculated at a 97.5% level of confidence and which expresses its potential future exposure. This metric is used internally for management purposes. ECR by Profiles Methodology introduces the concept of Exposure Profile per deal, where risk exposure may vary depending on the time-band considered. There is not a unique exposure figure per deal. However, many exposures figure as time-bands are affected and each time-band exposure equals the maximum exposure within the time-band. Deal risk aggregation per counterparty and per time-band requires aggregation of a Potential Future Exposure for each of the time-bands and considering the netting agreement for the Current Exposure and if applicable, collateral mitigation; so, there is an aggregated net exposure per counterparty as time-bands are impacted. For financial derivatives, where ECR is equal to the Current Exposure plus the nominal amount multiplied by the Risk Factor, the Profiles Methodology implies that PFE figure is not unique but is calculated for each of the time-bands. The Counterparty Credit Risk area compares, on a monthly basis, the nominal amounts used to calculate the PFE against the nominal amounts recognized in the accounting records and compares the Current Exposure amounts used for the Current Exposure of the ECR against the Current Exposure amounts also recognized in the accounting records. As of December 31, 2020 and 2021, the cumulative net credit risk exposure of the Bank was 45,372 million pesos and 32,803 million pesos, respectively. Counterparty credit risk comprises financial derivatives, repurchase agreements and securities lending. Received collateral is included with risk mitigation purposes to estimate exposure.

Prior to the exchange offer mentioned in Note 3, the Bank issued its own shares to compensate eligible employees for the portion payable in shares and classified this portion of the plan as an equity-settled plan. As a consequence of the exchange offer, the share-based payment plan was modified. The modification requires the Bank to acquire Banco Santander’s (Spain) shares to compensate eligible employees; accordingly, the share-based payment portion of the plan is now classified as a cash-settled plan. The Board of Directors is responsible for determining the specific amount of deferred compensation to be paid each year. If the objectives are achieved on each anniversary, the beneficiaries will receive cash and shares of Banco Santander (Spain) in thirds or fifths, as applicable, within thirty days after the first, second, third and, if applicable, fourth and fifth anniversary. At the end of the exchange offer, 264 million pesos were reclassified from Accumulated reserves within Shareholders’ equity to Other liabilities in the consolidated balance sheet. As of December 31, 2021, the plan has 3,276,039 shares committed of Banco Santander (Spain). During 2020 and 2021, the Bank recognized compensation expense relating to the share-based payment portion of the plan in the consolidated income statement for an amount of 226 million pesos and 54 million pesos, respectively. c) Bonus payment policies As a result of an internal policy of Banco Santander (Spain), a portion of the annual variable remuneration plan for the Identified Staff is deferred for a period of three one one Both the deferred and non-deferred portions are paid equally in cash and in shares for the corresponding payment periods. Once delivered, beneficiaries are obligated to keep the shares for a one-year period. Consistent with the share-based payments plan above, subsequent to the exchange offer mentioned in Note 3, the Bank is required to acquire Banco Santander’s (Spain) shares to compensate the Identified Staff. In 2019, 2020 and 2021, the Bank recognized the bonus of the Identified Staff in the consolidated income statement for an amount of 226 million pesos, 294 million pesos and 448 million pesos, respectively. The bonus of the Identified Staff for financial years 2019, 2020 and 2021 are paid according to the following percentages, depending on the time of payment and on the group to which the beneficiary belongs (the “Immediate Payment Percentage” to identify the portion for which payment is not deferred and the “Deferred Percentage” to identify the portion for which payment is deferred): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Beneficiaries Immediate Payment ​ ​ (Millions of Euros) ​ Percentage ​ ​ Deferred Percentage ​ ​ Deferred period ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Members of the Identified Staff with total variable remuneration ≥ 2.7 ​ 40 % 60 % 5 years Members of the Identified Staff with total variable remuneration ≥ 1.7 (< 2.7) ​ 50 % 50 % 5 years Other beneficiaries ​ 60 % 40 % 3 years ​ Taking the foregoing into account, the bonus for financial years 2019, 2020 and 2021 of the Identified Staff are paid as follows: ● Each beneficiary will receive in 2019, 2020 and 2021, depending on the group to which such beneficiary belongs, the Immediate Payment Percentage at the Initial Date applicable in each case, in halves and net of income tax (or withholdings), in cash and in shares (the “Initial Date”, meaning the specific date on which the Immediate Payment Percentage is paid). ● Payment of the Deferred Percentage of the bonus applicable in each case depending on the group to which the beneficiary belongs will be deferred over a period of three or five years and will be paid in thirds or fifths , as applicable, within thirty days of the anniversaries of the Initial Date, provided that the conditions described below are met. ● After deduction of any income taxes (or withholdings) applicable at any time, the net amount of the deferred portion will be paid in thirds or fifths, 50% in cash and the other 50% in shares. ● The beneficiaries receiving shares may not transfer them or hedge them directly or indirectly for one year as from each delivery of shares. In 2019, 2020 and 2021, the accrual of deferred remuneration is conditioned, in addition to the continued employment of the beneficiary in the Bank, to no assumptions in which there is a poor performance of the Bank as a whole or of a specific division or area of the Bank or of the exposures generated by the personnel, and at least the following factors must be considered: (i) significant failures in risk management committed by the Bank, or by a business unit or risk control unit; (ii) the increase suffered by the Bank or by a business unit of its capital needs, not foreseen at the time of generation of the exposures; (iii) regulatory sanctions or court rulings for events that could be attributable to the Bank or the personnel responsible for those. Also, the breach of internal codes of conduct of the Bank; and (iv) irregular behaviors, whether individual or collective, considering in particular the negative effects derived from the marketing of inappropriate products and the responsibilities of persons or bodies that made those decisions. If the abovementioned requirements are met on each delivery date, the bonus beneficiaries shall receive cash and shares, in thirds or fifths, as applicable, within thirty days of the first, second, third and, if applicable, fourth and fifth anniversary.

For level 2, the Bank uses quoted prices for similar liabilities in active markets. - Other financial liabilities: Their fair value has been estimated to be equal to their amortized cost since they are mainly composed by short-term balances. e) Significant restrictions See Note 49.d for significant restrictions on the ability to access or use the assets and settle the liabilities of the Bank as of December 31, 2021. f) Restriction on Accumulated reserves distribution As of December 31, 2020 and 2021, the Bank did not have any restriction on Accumulated reserves distribution, except for the legal reserve as mentioned in Note 29 (14,346 million pesos in legal reserve that includes 11,217 million pesos in legal reserve of Banco Santander México as of December 31, 2020 and 16,365 million pesos in legal reserve that includes 12,710 million pesos in legal reserve of Banco Santander México as of December 31, 2021), the remeasurement of defined benefit obligation and the recognition of equity-settled share-based payments. In addition, the Bank is restricted from distributing dividends that will result in non-compliance with minimum capitalization requirements established by the CNBV (see Note 30).

Risk management
Risk management	48. Risk management a) Cornerstones of the risk function The Bank’s risk principles below are compulsory. They comply with regulatory requirements and market best practices: 1. All employees are risk managers. Employees must understand the risks inherent in their jobs, avoiding them wherever the impact is unknown or exceeds the Bank’s risk appetite. 2. Engagement of Bank’s Management, who must act and communicate to manage risks consistently, supervise Bank’s risk culture and make sure to keep Bank’s risk profile within Bank’s risk appetite. 3. Independent risk management and control functions, consistent with the Bank´s model of three lines of defense. 4. A forward-looking, comprehensive approach to risk management and control for all businesses and risk types. 5. Detailed, timely information to detect, assess, manage and report risks to the appropriate level of management. The Bank’s holistic control structure stands on these principles, plus a series of strategic tools and procedures embedded in the Bank’s risk appetite statement, such as the risk profile assessment, scenario analysis, the risk reporting structure and the annual planning and budget process. Governance, policies and practices have been strengthened in response to the COVID-19 pandemic. A forward-looking and comprehensive approach to risk management and control across all business units and risk types allows the Bank to maintain a medium-low risk profile, through a risk appetite defined by the Board of Directors and the identification and assessment of existing and emerging risks. 1. Main risks of the Bank’s financial instruments The Bank's classification of risks ensures effective risk management, control and reporting. The Bank´s risk framework distinguishes these key risk types: ● Credit risk relates to financial loss arising from the default or credit quality deterioration of a customer or counterparty, to which the Bank has directly provided credit or assumed a contractual obligation. ● Market risk results from changes in interest rates, exchange rates, equities, commodities and other market factors, and from their effect on profit or capital. ● Liquidity risk occurs if liquid financial resources are not enough to meet due obligations or can only be obtained at a high cost. ● Structural risk relates to the changing value or margin of assets or liabilities in the banking book owing to changes in market factors and balance sheet behavior. It includes risks from pension activities or an inadequate quantity or quality of capital to fulfil internal business objectives, regulatory requirements or market expectations. ● Operational risk is the possibility of losses from inadequate or failed internal processes, people and systems or from external events. It includes legal risk and conduct risk. ● Regulatory compliance risk is the risk of not fulfilling legal and regulatory requirements and supervisors’ expectations, and may lead to fines, financial penalties or other sanctions. ● Model risk involves potential losses resulting from inaccurate predictions that lead to suboptimal decision making, or from a misuse or inadequate implementation of a model. ● Reputational risk consists of potential losses from damage to its reputation amongst employees, customers, shareholders/investors and the wider community. ● Strategic risk relates to losses or damage to the medium and long-term interests of the Bank’s key stakeholders owing to strategic decision-making, poor execution of strategy or failure to adapt to external developments. The Bank also considers environmental and climate related risk drivers (whether physical or transition-led) as factors that could impact the exiting risks in the medium and long-term. 2. Risk governance The Bank has a robust risk governance structure, aimed at ensuring the effective control of its risk profile in accordance with the risk appetite defined by the Board of Directors. The Board of Directors is responsible for approving the general framework for risk management and control, including tax risks. This governance framework is underpinned by the distribution of roles among the three lines of defense, a robust structure of committees and a strong relationship between Banco Santander México and its subsidiaries. All supported by the Bank-wide risk culture, Risk Pro. 2.1 Lines of defense The Bank follows a three lines of defense model to ensure effective risk management and control: ● First line: Businesses and functions that originate risks make up the first line of defense, which identifies, measures, controls, monitors and reports risks. It adheres to all risk management policies and procedures, making sure risks fit within risk appetite and other limits. ● Second line: Risk and Compliance & Conduct functions. Their role is to provide independent oversight and challenge to the risk management decisions from the first line of defense. The second line of defense ensures risks are managed according to risk appetite, strengthening our risk culture across the Bank. ● Third line: The Internal Audit function is independent to assure senior management about the quality and effectiveness of internal controls, risk management. governance and systems, helping to safeguard the Bank’s value. The Risk, Compliance and Conduct and Internal Audit functions are separated and independent and have direct access to the Board of Directors and its committees. 2.2 Risk committee structure The Board of Directors’ duties include risk and compliance management and control. It regularly revises and approves risk appetite and frameworks, strengthening and promoting the Bank’s risk culture. In its duties, the Board of Directors is supported by the risk supervision, regulation and compliance committee and the Bank’s executive committee. The Bank’s Chief Risk Officer (CRO) is responsible for devising risk strategy, overseeing all risks, and challenging and advising business lines on their risk management. The Bank’s Chief Compliance Officer (CCO) promotes the adherence to rules, supervisory requirements, principles of good conduct and values. This role determines the compliance and conduct strategy, and independently oversees and challenges the compliance and conduct risk management of the first line of defense. Both the Bank´s CRO and CCO have direct access, and report to, the risk supervision, regulation and compliance committee and the Board of Directors. The executive risk, risk control and general compliance committees are also at the top of the Bank's risk and compliance governance, with authority delegated by the Board of Directors, details of which are provided below: Executive risk committee This committee is responsible for risk management duties delegated by the Board of Directors, being authorized to accept, modify or scale those actions or transactions that may expose the Bank to a relevant risk as well as the most significant models. It takes the highest-level risk-related decisions within the Bank’s risk appetite. The CEO chairs this committee and it is composed of nominated executive officers and other Bank’s senior management members. Risk, Finance and Compliance and Conduct functions, among others, are represented. The CRO has the power of veto over the committee’s decisions. Comprehensive risk management committee This committee is responsible for risk control and for providing a holistic view of all risks. It determines if the risks business lines are being managed according to risk appetite. It also identifies, monitors and evaluates the impact of current and emerging risks on the Bank's risk profile. This committee is chaired by the CRO and it is composed of senior management members from the Risk, Compliance & Conduct, Finance, Accounting and Management Control functions are represented among others. General compliance committee The committee is responsible for reviewing significant compliance and conduct risk events, and evaluating related measures. It devises and assesses corrective actions for compliance risks owing to shortcomings in management and control or new risks. This committee is chaired by the CCO and it is composed of senior management from the Compliance & Conduct, Risk, Accounting and Management functions. The committee chair has a casting vote over committee resolutions. Risk functions have forums and regular meetings to manage and control the risks under their scope. Their responsibilities include: ● Reporting to the Bank’s CRO, the Bank’s CCO, the risk control committee and general compliance committee on risk management according to risk appetite. ● Monitoring each risk factor regularly. ● Overseeing measures to meet supervisor and auditor expectations. The Bank may set up additional governance for special cases. Amid the COVID-19 pandemic, coordination and communication are essential to making sure the Bank´s actions are effective, underpinned by written communication, meetings, reporting and enhanced governance The Bank monitored the pandemic intensively through special situation forums such as the credit risk war room, in addition to the Bank´s regular governance framework. In order to steer and supervise the review process of the IBOR Reform, the Bank established the IBOR steering group. This group is responsible for driving the project's strategic direction and take the required decisions to ensure a correct transition across all the Bank’s business units. The IBOR steering group operates in accordance with the methodology defined by the Bank's Execution Project Office and is chaired by the project's sponsor, the head of Santander Corporate & Investment Banking (SCIB), with the additional support of eight senior executives. 3. Management processes and tools The Bank has these effective risk management processes and tools: 3.1 Risk appetite and structure of limits Risk appetite is the volume and type of risks deemed prudent to assume for the business strategy of the Bank, even under unexpected circumstances. It considers adverse scenarios that could have a negative impact on capital and liquidity, profitability and/or the share price. The risk appetite statement (RAS) is annually set by the Board of Directors for the Bank. Every business unit sets their own risk appetite on an annual basis, aligned and embedded within the Bank’s consolidated statement. The Board of Directors is responsible for approving the respective risk appetite proposals. The Bank’s statement is then further cascaded down in the form of management limits and policies by risk type, portfolio and activity segment. Business model and risk appetite fundamentals The Bank's risk appetite is consistent with the risk culture and its unique business model built on customer focus, scale and diversification. At the core of the Bank´s risk appetite are: ● A medium-low target risk profile that is predictable, centred on retail and commercial banking, internationally diversified operations and strong market share; ● Stable, recurrent earnings and shareholder remuneration, sustained by sound capital, liquidity and sources of funding; ● An independent risk function with active senior management that embeds a strong risk culture and drives a sustainable return on capital; ● A global, holistic view through extensive control and monitoring of risks, businesses and markets; ● A focus on products the Bank knows well; ● A conduct model that protects the Bank's customers; and ● A remuneration policy that reconciles employees and executives' interests to risk appetite and long-term results. Risk appetite principles The principles informing the Bank´s risk appetite are: ● The Board of Directors and Bank’s Management. The Board of Directors is responsible for setting the risk appetite and for monitoring compliance with its requirements. ● An enterprise wide risk, risk profile backtesting and challenge. The risk appetite must consider all significant risks and facilitate an aggregate view of the risk profile with the use of quantitative metrics and qualitative indicators. ● Forward-looking view. The risk appetite must consider the desirable risk profile for the short and medium term, taking into account both the most plausible circumstances and adverse/stress scenarios. ● Embedding and alignment with strategic and business plans. The risk appetite is an integral part of the strategic and business planning, which is embedded in the daily management by cascading down the aggregated limits to those set at portfolio level, business unit or business line, as well as through the key risk appetite processes. ● Coherence across the various business units and a common risk language throughout the Bank. Each business unit’s risk appetite must be coherent with that of the Bank. ● Periodic review, backtesting and adoption of best practices and regulatory requirements. Monitoring and control mechanisms are established to ensure the risk profile is maintained, and the necessary corrective and mitigating actions are taken in the event of non-compliance . Limits structure, monitoring and control Risk appetite is expressed in qualitative terms and limits structured on these five core elements. ● Earnings volatility: - Maximum loss that the Bank can tolerate in an acute stress scenario. ● Solvency: - Minimum capital position that the Bank can tolerate in an acute stress scenario. - Maximum leverage that the Bank can tolerate in an acute stress scenario. ● Liquidity: - Minimum structural liquidity position. - Minimum liquidity horizon position that the Bank is willing to accept under a scenario of acute stress. - Minimum liquidity coverage position. ● Concentration: - Concentration in single names, sectors and portfolios. - Concentration in non-investment grade counterparties. - Concentration in large exposures. ● Non-financial risks: - Maximum operational risk losses. - Maximum risk profile. - Qualitative non-financial risk indicators: • Fraud. • Technological. • Security and cyber-risk. • Reputational. • Others. Compliance with risk appetite limits is regularly monitored, specialized control functions report on risk profile and compliance with limits to the Board of Directors and its committees every month. Risk appetite limits cascade down to business units, risk types and portfolios. This makes risk appetite an effective tool for managing risks. Management policies and limits are directly based on the principles and limits in the risk appetite statement. Key developments The Bank thoroughly reviewed the impact of COVID-19 and the adequacy of the Bank’s risk appetite to cope with the new environment. Risk appetite limits remained broadly unchanged despite extraordinarily challenging conditions. Management focused on enhancing control over market volatility, better representation and visibility of emerging risks such as cyber security and other non-financial risks. 3.2 Risk profile assessment (RPA) The Bank routinely identifies risk types to systematically and objectively evaluate its risk profile. This helps address major threats to the business plan and strategic objectives. Risk identification results inform the Bank´s risk profile assessment (RPA), which involves all lines of defense. It reinforces the Bank´s risk culture in analyzing how risks evolve and identifying improvement areas. The Bank´s RPA methodology covers these areas: ● Risk performance, to understand residual risks by type with international standard and indicators. ● Control environment, to measure the target-operating model of the Bank's advanced risk management according to regulatory requirements and best market practices. ● Forward-looking analysis, based on stress metrics and top risks to the strategic plan. The Bank upgraded its control environment standards and reviewed risk performance metrics, focusing on strategic, compliance and conduct metrics. The inclusion of the control score in the non-financial risks control environment enabled the Bank to better capture its risk profile. 3.3 Scenario analysis The scenarios that the Bank analysis include macroeconomic and other variables that can affect the risk profile in those markets in which the Bank operates. Scenario analysis is a useful tool for managing risks at all levels, so Banco Santander México can gauge its resilience under stressed conditions and formulate mitigating actions on income, capital and liquidity if needed. For this, the Research and Public Policy team is key in defining scenarios, as well as the Bank´s governance and control, including the review of top management and the three lines of defense. The Bank's scenario analyses are consistent and robust because the Bank: ● Creates and runs models that estimate how metrics such as credit losses will perform in the future. ● Back-tests and regularly challenges model results. ● Relies on expert opinions and a vast understanding of the Bank´s portfolios. ● Exerts robust control over models, scenarios, assumptions, results and mitigating management actions. The global economic uncertainty caused by the COVID-19 crisis made it exceptionally difficult for businesses to plan ahead. The Bank´s scenario analyses were key in identifying new action points, developing business responses, adjusting our risk strategy and preserving our strength and solvency. Applications of scenario analyses The Bank runs scenario analyses at all levels under a forward-looking approach that helps the Bank anticipate potential impacts on its solvency or liquidity. The Bank runs a systematic review of risk exposure under a baseline scenario and various adverse and favorable scenarios. Scenario analyses form an integral part of several key processes of the Bank: ● Regulatory uses: stress test scenarios using the guidelines set by the various regulators that supervise the Bank. ● Internal capital adequacy assessment (ICAAP) and liquidity assessment (ILAAP) for which the Bank follows its own methodology to assess capital and liquidity under stress scenarios and support planning and management. ● Risk appetite, which includes stressed metrics to set the maximum risk we can assume. The risk appetite and capital and liquidity scenario exercises are closely interrelated but have different frequencies and granularity. ● Climate change scenario analysis to identify scenarios of risks and opportunities. Pilot analyses are covering the wholesale portfolio. ● Recurrent risk management: - Budget and strategic planning process: when implementing a new risk approval policy, in the Bank’s risk profile assessment by senior management or when monitoring specific portfolios or lines of business. - Identification of Top risks based on a systematic process to identify and assess all risks to which the Bank is exposed. These Top risks are selected and a macroeconomic or idiosyncratic scenario is associated with each one, to assess their impact on the Bank. - Recovery plan that is drawn annually to establish the tools available to the Bank to survive in the event of an extremely severe financial crisis. The plan sets out a series of financial and macroeconomic stress scenarios, with differing degrees of severity, which include idiosyncratic and/or systemic events. - Credit and market risk stress test exercises not only as a response to regulatory exercises but also as a key tool integrated in the Bank’s risk management. 3.4 Risk Reporting Structure (RRS) The Bank´s reporting continues to streamline processes, controls and reports to senior management. The Enterprise Wide Risk Management team updates and compiles the risk profile overview under a forward-looking approach so senior management can assess actual and future risks and take appropriate actions. The reporting model of the Bank continues to be enhanced after the simplification and optimization of processes, the quality controls implemented and the strengthening of the effective communication to Bank’s Management. Furthermore, the overall view of all risks has been consolidated, based on complete, precise and recurring information allowing the Bank’s Management to assess the risk profile and decide accordingly. The Bank's strong risk reporting structure is characterized by: ● Balancing data, analysis and qualitative comments, including forward-looking measures, risk appetite alerts, limits and emerging risks. ● Covering all risk factors in the risk framework. ● Combining a holistic and reliable view with deeper analysis of each risk factor and the Bank´s markets. ● Following the same structure and criteria and provides a consolidated view to analyze all risks. ● Following risk data aggregation (RDA) criteria to report on metrics, ensuring data quality and consistency b) Credit risk 1. Introduction to the credit risk treatment Credit risk refers to a potential financial loss from the default or credit quality deterioration of a customer or other third party with whom the Bank has a contractual obligation. It is the most important risk, both in terms of exposure and capital consumption. It also includes counterparty risk, country risk and sovereign risk. Credit risk management The Bank identifies, analyses, controls and decides on credit risk based on a holistic view of the credit risk cycle, which includes the transaction, the customer and the portfolio. Business and risk areas and top managers are part of this process. Credit risk identification is key to managing and controlling the Bank's portfolios effectively. The Bank classifies external and internal risks in each business and adopts corrective and mitigating measures when needed through these processes: 1.1 Planning The Bank´s planning helps to set business targets and define specific action plans within our risk appetite framework. Strategic commercial plans (SCP) are a management and control tool the business and risk areas prepare for the Bank's credit portfolios. They determine commercial strategies, risk policies, resources and infrastructure, ensuring a holistic view of the portfolios. They provide managers with an updated view of credit portfolio quality to measure credit risk, run internal controls over the defined strategy coupled with regular monitoring, detect significant deviations in risk and potential impacts, and take corrective actions when necessary. They also align with the Bank's risk appetite capital targets. 1.2. Risk assessment and credit rating To analyze customers’ ability to meet contractual obligations, the Bank uses valuation and parameter estimation models in each of the segments. The Bank's credit quality valuation models are based on credit rating drivers, which the Bank monitors to calibrate and adjust the decisions and ratings they assign. Depending on each segment, drivers can be: ● Rating: from mathematical algorithms that have a quantitative model based on balance sheet ratios or macroeconomic variables, and a qualitative module supplemented by the credit analyst’s expert judgment. It is used for Santander Corporate and Investment Banking, corporate, institutional and small and medium-sized enterprises segments (with individualized treatment). ● Scoring: an automatic system to evaluate credit applications that assigns an individual score to customers for subsequent decision-making, generally in the retail and smaller small and medium-sized enterprises segments. The Bank's parameter estimation models follow econometric models built on the Bank's portfolios' historical defaults and losses. The Bank periodically reviews and evaluates models' appropriateness, predictive capacity, performance, granularity, compliance with policies and other related factors. The Bank reviews ratings with the latest available financial and economic information. The Bank has also increased the reviews for customers who are under closer observation or have automatic warnings in the risk management systems. 1.3. Credit risk mitigation techniques The Bank approves risks generally on the basis of borrowers’ ability to pay in fulfilment of financial obligations, notwithstanding any additional collateral or personal guarantees the Bank can require from them. To determine this, the Bank analyze funds or net cash flows from their businesses or income with no guarantors or the assets pledged as collateral. The Bank always considers guarantors and collateral when deciding to approve a loan as a secondary means of recourse if the first channel fails. In general, a guarantee is as a reinforcement measure added to a credit transaction to mitigate a loss due to a failure to meet a payment obligation. The Bank has credit risk mitigation techniques for various types of customer and products. Some are for specific transactions while others apply to a series of transactions. The Bank can be grouped into personal guarantees, guarantees in the form of credit derivatives or collateral. 1.4. Definition of limits, pre-classifications and pre-approvals The Bank uses strategic commercial plans to manage credit portfolios, defining limits for each of them and for new originations, in line with the Bank´s credit risk appetite and its target risk profile. Transposing the risk appetite to portfolio management strengthens controls over our credit portfolios. The Bank´s limits, pre-classifications and pre-approvals processes determine the risk that can be assumed with each customer. The business and risk areas set risk limits that are approved by the executive risk committee (or delegated committees) and should reflect a transaction’s expected risk return. The Bank applies various limits models to each segment: ● Large corporate groups: are subject to a pre-classification model based on a system for measuring and monitoring economic capital. Pre-classification models express the level of risk the Bank is willing to assume in transactions with customers/groups in terms of capital at risk, nominal cap and maximum tenors. To manage limits with financial entities, the Bank uses Credit Equivalent Risk (CER), which includes actual and expected risks with customers according to risk appetite and credit policies. ● Corporates and institutions: that meet certain requirements (strong relationships, rating, etc.): The Bank uses simpler pre-classification model with an internal limit. It establishes a reference point in a customer's level of risk based on repayment capacity, overall indebtedness and a pool of banks. Transactions with large corporates, corporates and institutions above certain limits or with special characteristics could require approval from a senior credit analyst or a committee. ● For individual customers and small and medium-sized enterprises with low turnover, the Bank manages large volumes of credit transactions with automatic decision models to classify customers and transactions. 1.5. Scenario analysis The Bank´s scenario analysis determine the potential risks in its credit portfolios and provide a better understanding of the Bank´s portfolios performance under various macroeconomic conditions. They allow the Bank to anticipate management strategies that will avoid future deviations from defined plans and targets. They simulate the impact of alternative scenarios in portfolios’ credit parameters (PD, LGD) and expected credit losses. The Bank compares findings with portfolios’ credit profile indicators to find the right measures for managers to take. Credit risk management of portfolios and strategic commercial plans incorporate scenario analyses. 1.6. Monitoring Regularly monitoring business performance and comparing it to pre-defined plans is key to our management of risk. The Bank's holistic monitoring of customers helps detect impacts on risk performance and credit quality early. The Bank assigns customers a classification with a predefined course of action and ad hoc measures to correct any deviations. Monitoring, which considers transaction forecasts and characteristics, in addition to changes in classification, is performed by risk teams supported by the Internal Audit unit and is based on customer segmentation: ● For Santander Corporate and Investment Banking, monitoring is initially a function of business managers and risk analysts who maintain direct relationships with customers, manage portfolios and provide the Bank with an up-to-date view of customers’ credit quality to anticipate concerning situations. ● For commercial banking, institutions and small and medium-sized enterprises assigned a credit analyst, the Bank tracks customers requiring closer monitoring and review their ratings based on relevant indicators. ● Monitoring of individual customers, businesses and small and medium-sized enterprises follows a system of automatic alerts to detect shifts in portfolios’ performance. In addition to monitoring customer credit quality, the Bank defines control procedures to analyze portfolios and performance, as well as any deviations from planning or approved alert levels. 1.7. Recovery and collections management The Collections and Recoveries area carries out recoveries, which are important to risk management. It defines an enterprise-wide management strategy with guidelines and general lines of action for the Bank based on the economic environment. business model and other recovery conditions. Recovery management follows regulatory requirements set out on the management of non-performing and forborne exposures. In addition, the Bank applies specific policies on recovery management that include the principles of the different strategies. The Collections and Recoveries areas directly manage customers. As sustained value creation is based on effective and efficient collections, digital channels that develop new customer relations are gaining importance. The Bank diverse customer base requires segmentation to manage recoveries appropriately. The highly technological and digital processes of the Bank helps to attend large groups of customers with similar profiles and products. the Bank's personalized management, however, focuses on customer profiles that require a special manager and approach. The Bank splits recovery management into four phases: arrears, non-performing loans, write-offs and foreclosed assets. The Bank may uses mechanisms to rapidly reduce assets like sales of foreclosed assets or non-performing loans pool sales. The Bank constantly seeks alternatives to legal action in order to collect debt. The Bank includes debt instruments as written-off loans (even if they are not past-due) if an individual analysis of the solvency of a transaction and the borrower leads us to believe recovery is remote due to a notorious and unrecoverable impairment. Though this may lead to full or partial cancellation and de-recognition of the gross carrying amount of debt, it does not mean that the Bank interrupts negotiations and legal proceedings to recover debt. 2.

Foreign currency transactions	a) Foreign currency transactions i. Functional currency The functional currency of all entities comprising the Bank is the Mexican Peso (hereinafter, peso or $). Therefore, all balances and transactions denominated in currencies other than the peso are deemed to be denominated in foreign currency. ii. Foreign currency In preparing the consolidated financial statements, transactions in currencies other than the Bank’s functional currency (foreign currencies) are recognized at the exchange rates prevailing at the dates of the transactions. Monetary items denominated in foreign currencies are retranslated to the functional currency at the rates prevailing at the consolidated balance sheet date. Non-monetary items carried at fair value in foreign currencies are retranslated to the functional currency at the rates prevailing at the date when the fair value was determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated. The Bank performs a large number of foreign currency transactions, mainly in USD. The transactions, assets and liabilities denominated in foreign currencies are translated to pesos based on the exchange rates published by the Mexican Central Bank. The 48-hour exchange rate used as of December 31, 2020 was $19.9087 per one USD and the “day-end” exchange rate used as of December 31, 2021 was $20.5075 per one USD. iii. Recognition of exchange differences The exchange differences arising on the translation of foreign currency balances to the functional currency are recognized at their net amount under Exchange differences (net) in the consolidated income statement, except for exchange differences arising on financial instruments at fair value through profit or loss, which are recognized under Gains/(losses) on financial assets and liabilities (net) in the consolidated income statement without distinguishing them from other changes in fair value and for exchange differences arising on non-monetary items measured at fair value through other comprehensive income, which are recognized under Valuation adjustments in other comprehensive income.
Basis of consolidation	b) Basis of consolidation i. Subsidiaries The consolidated financial statements incorporate the financial statements of Banco Santander México and entities (including structured entities) controlled by Banco Santander México together with its subsidiaries. Control is achieved when Banco Santander México has all of the following: ● has power over the investee; ● is exposed, or has rights, to variable returns from its involvement with the investee; and ● has the ability to use its power to affect its returns. Banco Santander México reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control listed above. When Banco Santander México has less than a majority of the voting rights of an investee, it has power over the investee when the voting rights are sufficient to give it the practical ability to direct the relevant activities of the investee unilaterally. Banco Santander México considers all relevant facts and circumstances in assessing whether or not Banco Santander México’s voting rights in an investee are sufficient to give it power, including: ● the size of Banco Santander México’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders; ● potential voting rights held by Banco Santander México, other vote holders or other parties; ● rights arising from other contractual arrangements; and ● any additional facts and circumstances that indicate that Banco Santander México has, or does not have, the current ability to direct the relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings. Consolidation of a subsidiary begins when Banco Santander México obtains control over the subsidiary and ceases when Banco Santander México loses control of the subsidiary. Specifically, the results of a subsidiary acquired or disposed of during the year are included in the consolidated income statement and other comprehensive income from the date Banco Santander México gains control until the date when Banco Santander México ceases to control the subsidiary. Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with Banco Santander México’s accounting policies. The financial statements of the subsidiaries are fully consolidated with those of Banco Santander México. Accordingly, all intragroup assets and liabilities, equity, income, expenses and cash flows relating to transactions between the members of the Bank are eliminated on consolidation. Non-controlling interests in subsidiaries are identified separately from the Bank’s equity therein. Those interests of non-controlling shareholders that are present ownership interests entitling their holders to a proportionate share of net assets upon liquidation may initially be measured at fair value or at the non-controlling interests’ proportionate share of the fair value of the acquiree’s identifiable net assets. The choice of measurement is made on an acquisition-by-acquisition basis. Other non-controlling interests are initially measured at fair value. Subsequent to acquisition, the carrying amount of non- controlling interests is the amount of those interests at initial recognition plus the non-controlling interests’ share of subsequent changes in consolidated total equity. The consolidated income statement and each component of other comprehensive income are attributed to the owners of the Bank and to the non-controlling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Bank and to the non-controlling interests even if these results in the non-controlling interests having a deficit balance (see Note 27). The share of third parties of the consolidated total equity is presented under Non-controlling interests in the consolidated balance sheet (see Note 27). Their share of the profit for the year is presented under Profit attributable to non-controlling interests in the consolidated income statement. On acquisition of control of a subsidiary that meets the definition of a business, its assets, liabilities and contingent liabilities are recognized at their acquisition date fair value. Any excess of the acquisition cost, the amount recognized for non-controlling interests of the acquiree and the fair value of the acquirer’s previous held equity interest in the acquiree over the fair values of the identifiable net assets acquired are recognized as goodwill (see Note 16). Negative differences are recognized in the consolidated income statement on the date of acquisition. The results of subsidiaries acquired during the year are included in the consolidated income statement from the date of acquisition to year-end. Similarly, the results of subsidiaries for which control is lost during the year are included in the consolidated income statement from the beginning of the year to the date of disposal. A listing of the subsidiaries included in the consolidated financial statements as of December 31, 2020 and 2021 is shown in Note 49. ii. Investments in associated entities An associate is an entity over which the Bank has significant influence and that is neither a subsidiary nor an interest in a joint venture. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. The results, assets and liabilities of associated entities are incorporated in the consolidated financial statements using the equity method of accounting, except when the investment, or a portion thereof, is classified as held for sale, in which case it is accounted for in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations An investment in an associate is accounted for using the equity method from the date on which the investee becomes an associate. On acquisition of the investment in an associate, any excess of the cost of the investment over the Bank’s share of the net fair value of the identifiable assets and liabilities of the investee is recognized as goodwill, which is included within the carrying amount of the investment. Any excess of the Bank’s share of the net fair value of the identifiable assets and liabilities over the cost of the investment, after reassessment, is recognized immediately in the consolidated income statement in the period in which the investment is acquired. The requirements of IAS 36 are applied to determine whether it is necessary to recognize any impairment loss with respect to the Bank’s investment in an associate. When necessary, the entire carrying amount of the investment (including goodwill) is tested for impairment in accordance with IAS 36 as a single asset by comparing its recoverable amount (higher of value in use and fair value less costs of disposal) with its carrying amount. Any impairment loss recognized forms part of the carrying amount of the investment. Any reversal of that impairment loss is recognized in accordance with IAS 36 to the extent that the recoverable amount of the investment subsequently increases. The Bank discontinues the use of the equity method from the date when the investment ceases to be an associate, or when the investment is classified as held for sale. When the Bank retains an interest in the former associate and the retained interest is a financial asset, the Bank measures the retained interest at fair value at that date and the fair value is regarded as its fair value on initial recognition in accordance with IFRS 9. The difference between the carrying amount of the associate at the date the equity method was discontinued, and the fair value of any retained interest and any proceeds from disposing of a part interest in the associate is included in the determination of the gain or loss on disposal of the associate. In addition, the Bank accounts for all amounts previously recognized in other comprehensive income in relation to that associate on the same basis as would be required if that associate had directly disposed of the related assets or liabilities. Therefore, if a gain or loss previously recognized in other comprehensive income by that associate would be reclassified to the consolidated income statement on the disposal of the related assets or liabilities, the Bank reclassifies the gain or loss from consolidated total equity to the consolidated income statement (as a reclassification adjustment) when the associate is disposed of. When the Bank reduces its ownership interest in an associate but the Bank continues to use the equity method, the Bank reclassifies to the consolidated income statement the proportion of the gain or loss that had previously been recognized in other comprehensive income relating to that reduction in ownership interest if that gain or loss would be reclassified to the consolidated income statement on the disposal of the related assets or liabilities. When a Bank’s subsidiary transacts with an associate or a joint venture of the Bank, profits and losses resulting from the transactions with the associate are recognized in the consolidated financial statements only to the extent of interests in the associate that are not related to the Bank. The Bank applies IFRS 9, including the impairment requirements, to long-term interests in an associate to which the equity method is not applied and which form part of the net investment in the investee. Furthermore, in applying IFRS 9 to long-term interests, the Bank does not take into account adjustments to their carrying amount required by IAS 28 Investments in Associates and Joint Ventures As of December 31, 2020 and 2021, the Bank maintained an investment in an associated entity as detailed in Note 49.a. iii. Structured entities When the Bank incorporates entities, or holds ownership interests therein, to enable its customers to access certain investments, or for the transfer of risks or other purposes (also called structured entities since the voting or similar power is not a key factor in deciding who controls the entity), the Bank determines, using internal criteria and procedures and taking into consideration the applicable legislation, whether control (as defined above) exists and, therefore, whether these entities should be consolidated. These structured entities include securitization special purpose vehicles (SPV) and employee benefit trusts (EBT) established for employee share-based plans, which are consolidated as it is considered that the Bank exercise control over these structured entities. Share-based payments are discussed in Note 42.b, 42.c, 42.d. and 43.b iv. Business combinations Acquisitions of businesses are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value, which is calculated as the sum of the acquisition-date fair values of the assets transferred by Banco Santander México, liabilities incurred by Banco Santander México to the former owners of the acquiree and the equity interests issued by the Bank in exchange for control of the acquiree. Acquisition-related costs are recognized in the consolidated income statement as incurred. At the acquisition date, the identifiable assets acquired and the liabilities assumed are recognized at their fair value, except that: ● deferred tax assets or liabilities, and assets or liabilities related to employee benefit arrangements are recognized and measured in accordance with IAS 12 Income Taxes and IAS 19 Employee Benefits , respectively; ● liabilities or equity instruments related to share-based payment arrangements of the acquiree or share-based payment arrangements of Banco Santander México entered into to replace share-based payment arrangements of the acquiree are measured in accordance with IFRS 2 at the acquisition date; and ● assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 are measured in accordance with that Standard. Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree, and the fair value of the acquirer’s previously held equity interest in the acquiree (if any) over the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. If, after reassessment, the net of the acquisition-date amounts of the identifiable assets acquired and liabilities assumed exceeds the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree and the fair value of the acquirer’s previously held interest in the acquiree (if any), the excess is recognized immediately in the consolidated income statement as a bargain purchase gain. When the consideration transferred by Banco Santander México in a business combination includes a contingent consideration arrangement, the contingent consideration is measured at its acquisition-date fair value and included as part of the consideration transferred in a business combination. Changes in fair value of the contingent consideration that qualify as measurement period adjustments are adjusted retrospectively, with corresponding adjustments against goodwill. Measurement period adjustments are adjustments that arise from additional information obtained during the ‘measurement period’ (which cannot exceed one year from the acquisition date) about facts and circumstances that existed at the acquisition date. The subsequent accounting for changes in the fair value of the contingent consideration that do not qualify as ‘measurement period’ adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates and its subsequent settlement is accounted for within equity. Other contingent consideration is remeasured to fair value at subsequent reporting dates with changes in fair value recognized in the consolidated income statement. When a business combination is achieved in stages, the Bank’s interests previously held in the acquired entity are remeasured to its acquisition-date fair value and the resulting gain or loss, if any, is recognized in the consolidated income statement. Amounts arising from interests in the acquiree prior to the acquisition date that have previously been recognized in other comprehensive income are reclassified to the consolidated income statement, where such treatment would be appropriate if that interest were disposed of. If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, Banco Santander México reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the amounts recognized at that date. v. Business combinations under common control A common control transaction is a transfer of net assets or an exchange of equity interests between entities under the control of the same parent. A common-control transaction has no effect on the Ultimate Parent’s consolidated financial statements. The net assets are derecognized by the transferring entity and recognized by the receiving entity at their historical carrying amounts. Any difference between the consideration paid or received and the carrying amounts of the net assets is recognized in Accumulated reserves within Shareholders’ equity in the consolidated balance sheet. vi. Changes in Banco Santander México’s ownership interests in existing subsidiaries Changes in Banco Santander México’s ownership interests in subsidiaries that do not result in Banco Santander México losing control over the subsidiaries are accounted for as equity transactions, no gain or loss is recognized in the consolidated income statement and the initially recognized goodwill is not remeasured. The carrying amounts of Banco Santander México’s interests and the non-controlling interests are adjusted to reflect the changes in their relative interests in the subsidiaries. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in Accumulated reserves within Shareholders’ equity in the consolidated balance sheet and attributed to owners of Banco Santander México. When Banco Santander México loses control of a subsidiary, a gain or loss is recognized in the consolidated income statement and is calculated as the difference between (i) the aggregate of the fair value of the consideration received and the fair value of any retained interest and (ii) the previous carrying amount of the assets (including goodwill), and liabilities of the subsidiary and any non-controlling interests. All amounts previously recognized in other comprehensive income in relation to that subsidiary are accounted for as if Banco Santander México had directly disposed of the related assets or liabilities of the subsidiary (i.e., reclassified to the consolidated income statement or transferred to another category of equity as specified/permitted by applicable IFRS). The fair value of any investment retained in the former subsidiary at the date when control is lost is regarded as the fair value on initial recognition for subsequent accounting under IFRS 9, when applicable, the cost on initial recognition of an investment in an associate or a joint venture.
Definitions and classification of financial instruments	c) Definitions and classification of financial instruments i. Definitions A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. Financial assets and financial liabilities are recognized when the Bank becomes a party to the contractual provisions of the financial instruments. An equity instrument is a contract that evidences a residual interest in the assets of the issuing entity after deducting all of its liabilities. A financial derivative is a financial instrument or other contract within the scope of IFRS with all three of the following 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 in the case of a non-financial variable that the variable is not specific to a party to the contract (sometimes called the “underlying”); ● it requires no initial net investment or an initial net investment that is smaller than would be required for other types of contracts that would be expected to have a similar response to changes in market factors; and ● it is settled at a future date. Hybrid financial instruments are contracts that simultaneously include a non-derivative host contract together with a financial derivative, known as an embedded derivative, that is not separately transferable and has the effect that some of the cash flows of the hybrid contract vary in a way similar to a stand-alone financial derivative. Compound financial instruments are contracts that simultaneously create for their issuer a financial liability and an equity instrument (such as convertible bonds, which entitle their holders to convert them into equity instruments of the issuer). The following transactions are not treated for accounting purposes as financial instruments: ● Investments in associated entities (see Note 49) ● Rights and obligations under employee benefit plans (see Note 24.c). ● Contracts and obligations relating to employee remuneration based on own equity instruments. ii. Classification of financial assets for measurement purposes Financial assets are initially classified into the various categories used for management and measurement purposes, unless they have to be presented as Non-current assets held for sale or they relate to Cash and balances with the Central Bank or Hedging financial derivatives, which are reported separately. The classification criteria depends on the Bank’s business model for managing the financial assets and the contractual terms of its cash flows. The Bank reclassifies financial assets when, and only when, its business model for managing those financial assets changes. The business model reflects how the Bank manages the financial assets in order to generate cash flows. That is, whether the Bank’s objective is to collect the contractual cash flows from financial assets on specified dates that are solely payments of principal and interest (SPPI), or is to collect both the contractual cash flows and cash flows arising from the sale of financial assets. In determining the appropriate business models for a group of financial assets and assessing the SPPI requirements, the Bank takes into account the following factors: ● How key management personnel are assessed and are reported on the performance of the business model and the financial assets held in the business model. ● The risks that affect the performance of the business model (and the financial assets held in the business model) and, specifically, the way in which these risks are managed. ● How business managers are remunerated. ● The evaluation of the experience on how the cash flows of financial assets were collected. ● The frequency and volume of sales in previous years, as well as expectations of future sales. ● How certain contractual features are considered (i.e., interest rate reset frequency, prepayment commissions, among others) that significantly affect future cash flows. ● The assessment of a compensation paid or received on early termination that could result in cash flows that are not SPPI. ​ Where the business model is to hold financial assets to collect contractual cash flows or to collect both the contractual cash flows and cash flows arising from the sale of financial assets, the Bank assesses whether the financial assets’ cash flows represent SPPI. In making this assessment (SPPI test), the Bank considers whether the contractual cash flows are consistent with a basic lending arrangement. ​ Depending on these factors, the financial asset can be measured at amortized cost, at fair value through other comprehensive income (FVTOCI), or at fair value through profit or loss (FVTPL). IFRS 9 also establishes an option to designate a financial instrument at FVTPL, under certain conditions. ​ Where the contractual terms of the cash flows introduce exposures to risk or volatility that are inconsistent with a basic lending arrangement, the related financial assets are classified and measured at FVTPL. Financial assets that do not meet the criteria for being classified and measured at amortized cost or FVTOCI are classified and measured at FVTPL. Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are SPPI. iii. Classification of financial assets for presentation purposes Financial assets are classified by nature into the following items in the consolidated balance sheet: - Cash and balances with the Central Bank: cash balances and balances receivable including the compulsory deposits with the Central Bank. - Loans and advances to credit institutions: loans of any nature, including deposits and money market transactions, provided to credit institutions. - Loans and advances to customers: debit balances of all loans granted to customers by the Bank. - Debt instruments: bonds and other debt securities that represent a debt obligation for their issuer and that bear interest. - Equity instruments: financial instruments issued by other entities, such as shares, which have the nature of equity instruments for the issuer, other than investments in subsidiaries, associates or jointly controlled entities. - Trading derivatives: fair value in favour of the Bank of financial derivatives, which do not form part of hedge accounting, including embedded derivatives separated from hybrid financial instruments. - Hedging derivatives: fair value of financial derivatives in favour of the Bank, including embedded derivatives separated from hybrid financial instruments, designated as hedging instruments in hedge accounting. iv. Classification of financial liabilities for measurement purposes Financial liabilities are initially classified into the various categories used for management and measurement purposes, unless they relate to hedging financial derivatives, which are reported separately. Financial liabilities are classified for measurement purposes into one of the following categories: - Financial liabilities at fair value through profit or loss: financial liabilities incurred for the purpose of generating a profit in the near term from fluctuations in their prices, financial derivatives not designated as hedging instruments and financial liabilities arising from the outright sale of financial assets acquired under reverse repurchase agreements, securities loans and sales of borrowed securities (short positions). Additionally, financial liabilities are included in this category when such classification provides more relevant information regarding the financial liability, either because this eliminates or significantly reduces recognition or measurement inconsistencies (accounting mismatches) that would otherwise arise from measuring the liabilities or recognizing the gains or losses on them on different bases, or because a group of financial liabilities or financial assets and liabilities is managed and its performance is evaluated on a fair value basis, in accordance with a documented risk management or investment strategy, and information about the group is provided on that basis to the Bank’s key management personnel. - Financial liabilities at amortized cost: financial liabilities, irrespective of their instrumentation and maturity, not included in any of the above-mentioned categories, which arise from the ordinary borrowing activities or financing received. v. Classification of financial liabilities for presentation purposes Financial liabilities are classified by nature into the following items in the consolidated balance sheet: - Deposits: all repayable balances received in cash by the Bank, other than those classified as marketable debt securities and those having the substance of subordinated liabilities. This item also includes cash bonds and cash consignments received, amount of which may be invested without restriction. Deposits are classified based on the type of depositor as follows: - Deposits from the Central Bank: deposits and repurchase agreements of any nature with the Central Bank. - Deposits from credit institutions: deposits of any nature, including credit received, money market transactions and repurchase agreements in the name of credit institutions. - Customer deposits: deposits and repurchase agreements. - Marketable debt securities: bonds and other debt represented by marketable securities, other than those having the substance of subordinated liabilities. - Trading derivatives: fair value of financial derivatives with a liability balance, including embedded derivatives separated from the host contract, which do not form part of hedge accounting. - Short positions: financial liabilities arising from the outright sale of financial assets acquired under reverse repurchase agreements, securities loans and sales of borrowed securities. - Subordinated liabilities: financing received which, for the purposes of payment priority, ranks behind ordinary debt. This category also includes the component that has the consideration of financial liability of compound financial instruments issued by the Bank, which form part of the Bank’s capital management for regulatory purposes, but do not meet the requirements for classification as equity for accounting purposes. - Hedging derivatives: fair value of the Bank’s liability in respect of financial derivatives, including embedded derivatives separated from hybrid financial instruments, designated as qualified hedging instruments in hedge accounting.
Measurement of financial assets and liabilities and recognition of fair value changes	d) Measurement of financial assets and liabilities and recognition of fair value changes In general, financial assets and liabilities are initially recognized at fair value, which, in the absence of evidence to the contrary, is deemed to be the transaction price. The amount initially recognized for financial instruments not measured at FVTPL is adjusted for transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVTPL are recognized in the consolidated income statement. If the fair value of a financial instrument at initial recognition differs from the transaction price, that financial instrument shall be accounted for at that date as follows: - if that fair value is evidenced by a quoted price in an active market for an identical asset or liability (i.e., a Level 1 input) or based on a valuation technique that uses only data from observable markets, the difference between the fair value at initial recognition and the transaction price shall be recognized as a gain or loss. - in all other cases, adjusted to defer the difference between the fair value at initial recognition and the transaction price. After initial recognition, that deferred difference shall be recognized as a gain or loss only to the extent that it arises from a change in a factor (including time) that market participants would take into account when pricing the asset or liability. Financial assets and liabilities are subsequently measured at each period-end as follows: i. Measurement of financial assets Financial assets measured at fair value The fair value of a financial instrument on a given date is taken to be the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The most objective and common reference for the fair value of a financial instrument is the price that would be paid for it on an active and transparent active market (quoted price or market price). If there is no market price for a given financial instrument, its fair value is estimated on the basis of the price established in recent transactions involving similar instruments and, in the absence thereof, of valuation techniques commonly used by the international financial community, taking into account the specific features of the instrument to be measured and, particularly, the various types of risk associated with it. All financial assets are accounted for at the trade date. All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the time frame established by regulation or convention in the marketplace. Subsequent measurement of financial assets depends on the Bank’s business model for managing the financial assets and the cash flows characteristics of the financial asset. The Bank classifies its financial assets into three measurement categories: - Amortized cost: financial instruments under a business model whose objective is to collect principal and interest cash flows, over which there is no significant unjustified sales, fair value is not a key element in the management of these financial assets and contractual conditions give rise to cash flows on specific dates, which are SPPI. In this sense, unjustified sales are considered those other than those related to an increase in the credit risk of the asset; unanticipated funding needs (stress case scenarios). Additionally, the characteristics of its contractual cash flows represent substantially a “basic financing agreement”. Interest income from these financial assets is included in Interest income in the consolidated income statement using the effective interest rate method. Any gain or loss arising on derecognition is recognized directly in the consolidated income statement. Foreign exchange gains and losses are presented in Exchange differences (net) and impairment losses are presented within Impairment losses on financial (net) in the consolidated income statement. - FVTOCI: financial instruments held in a business model whose objective is to collect principal and interest cash flows and the sale of these financial assets, where fair value is a key factor in their management. Additionally, the contractual cash flow characteristics substantially represent a “basic financing agreement”. Changes in the fair value are taken through other comprehensive income, except for the recognition of impairment gains and losses, interest income and foreign exchange gains and losses on the financial assets’ amortized cost, which are recognized in the consolidated income statement. When the financial assets are derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified to profit or loss and recognized in Gains/(losses) on financial assets and liabilities (net) in the consolidated income statement. Interest income from these financial assets is included in Interest income calculated using the effective interest method in the consolidated income statement using the effective interest rate method. Foreign exchange gains and losses are presented in Exchange differences (net) and impairment losses are presented within Impairment losses on financial assets on financial assets not at fair value through profit or loss (net) in the consolidated income statement. - FVTPL: financial instruments included in a business model whose objective is not obtained through the above-mentioned models, where fair value is a key factor in managing of these financial assets, and financial instruments whose contractual cash flow characteristics do not substantially represent a “basic financing agreement”. Changes in the fair value of financial assets at FVTPL are recognized in profit or loss and presented net within Gains/(losses) on financial assets and liabilities (net) in the consolidated income statement in the period in which it arises. Interest income from these financial assets is included as a separate line item within the consolidated income statement in Other interest and similar income using the effective interest rate method. Loans with different components The Bank originates loans to hold to maturity and to collect and sell or sub-participate to other lenders, resulting in a transfer of substantially all the risk and rewards and derecognition of the loan or portion of it. The Bank considers the activities of lending to hold and lending to collect and sell or sub-participate as two separate business models. Financial assets considered to be within a business model that has an objective to hold the financial assets to collect contractual cash flows are accounted for at amortized cost. Financial assets considered to be within a business model that has an objective to collect contractual cash flows and to sell or sub-participate to other lenders are accounted for at FVTOCI. Amortized cost and effective interest method The amortized cost is the amount at which the financial asset is measured at initial recognition minus the principal repayments, plus the cumulative amortization using the effective interest method of any difference between that initial amount and the maturity amount, adjusted for any allowance for impairment losses. The gross carrying amount of a financial asset is the amortized cost of a financial asset before adjusting for any allowance for impairment losses. The effective interest method is a method of calculating the amortized cost of a financial instrument and of allocating interest income over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments or receipts through the expected life of the financial asset or financial liability to the gross carrying amount of a financial asset or to the amortized cost of a financial liability. The calculation does not consider expected credit losses and includes transaction costs, premiums or discounts and fees and basis points paid or received that are integral to the effective interest rate, such as origination fees. For purchased or originated credit-impaired (POCI) financial assets, the Bank calculates the credit-adjusted effective interest rate, which is calculated based on the amortized cost of the financial asset instead of its gross carrying amount and incorporates the impact of expected credit losses in estimated future cash flows. Modification of contractual cash flows When the contractual cash flows of a financial asset are renegotiated or otherwise modified and the renegotiation or modification does not result in cash flows that are substantially different, the modification does not result in derecognition. In which case, the Bank recalculates the gross carrying amount of the financial asset and recognizes a modification gain or loss in profit or loss. The gross carrying amount of the financial asset shall be recalculated as the present value of the renegotiated or modified contractual cash flows that are discounted at the financial asset’s original effective interest rate or credit-adjusted effective interest rate for POCI financial assets. Modification of loans and advances to customers The Bank sometimes renegotiates, refinances or otherwise modifies the contractual cash flows of loans and advances to customers. When this happens, the Bank assesses whether or not the new terms are substantially different to the original terms. The Bank does this by considering, among others, the following factors: ● When the borrower is in financial difficulty, whether the modification merely reduces the contractual cash flows to amounts the borrower is expected to be able to pay. ● Whether any substantial new terms are introduced that affects the risk profile of the loan. ● Significant extension of the loan term when the borrower is not in financial difficulty. ● Significant change in the interest rate. ● Change in the currency the loan is denominated in. ● Insertion of collateral, other security or credit enhancement that significantly affect the credit risk associated with the loan. ● The modification is such that the loan would no longer meet the SPPI test. Modification of loans and advances to customers in the context of COVID-19 pandemic During 2020, as a consequence of COVID - two The relief measures contained in the Support Program resulted in a modification to the contractual terms of the loans subject to the Support Program, that did not result in derecognition of the financial assets under IFRS 9. As of December 31, 2021, the Support Program is not active. Details on the modification gain or loss of financial assets are presented in Note 11.g. Derecognition due to substantial modification of terms and conditions The Bank derecognizes a financial asset, such as a loan to a customer, when the terms and conditions have been changed or renegotiated to the extent that, substantially, it becomes a new loan, with the difference recognized in profit or loss, to the extent that an impairment loss has not already been recognized. The new financial asset is initially recognized at fair value. There is limited guidance in IFRS 9 with respect to determining whether a modification of a financial asset results in derecognition, hence this assessment is based on qualitative factors and may be subject to judgment. Interest income Interest income is calculated by applying the effective interest rate to the gross carrying amount of financial assets measured at FVTPL, at FVTOCI and at amortized cost, except for: - POCI financial assets, for which the original credit-adjusted effective interest rate is applied to the amortized cost of the financial asset. - Financial assets that are not POCI but have subsequently become credit-impaired (or Stage 3), for which interest income is calculated by applying the effective interest rate to their amortized cost. Debt instruments classified as at FVTOCI Debt instruments classified as at FVTOCI are initially measured at fair value plus transaction costs. Subsequently, changes in the carrying amount of these financial assets as a result of foreign exchange gains and losses, impairment losses and interest income calculated using the effective interest method are recognized in the consolidated income statement. The amounts that are recognized in the consolidated income statement are the same as the amounts that would have been recognized in the consolidated income statement, if these financial assets had been measured at amortized cost. All other changes in the carrying amount of these financial assets are recognized in other comprehensive income and accumulated under Valuation adjustments - Financial assets at fair value through other comprehensive income. When these financial assets are derecognized, the cumulative gains or losses previously recognized in other comprehensive income are reclassified to the consolidated income statement. Equity instruments The Bank designates at initial recognition and subsequently measures all equity instruments as at FVTPL, unless the Bank elects to present irrevocably fair value gains and losses on equity instruments in other comprehensive income. Designation of equity instruments as at FVTOCI is not permitted if the equity investment is held for trading or if it is contingent consideration recognized by an acquirer in a business combination. A financial asset is held for trading if: ● it has been acquired principally for the purpose of selling it in the near term; or ● on initial recognition it is part of a portfolio of identified financial instruments that the Bank manages together and has evidence of a recent actual pattern of short-term profit-taking; or ● it is a financial derivative instrument (except for a financial derivative that is a financial guarantee contract or a designated and effective hedging instrument). Investments in equity instruments at FVTOCI are initially measured at fair value plus transaction costs. Subsequently, they are measured at fair value with gains and losses arising from changes in fair value recognized in other comprehensive income under Valuation adjustments - Financial assets at fair value through other comprehensive income. The cumulative gain or loss is not reclassified to profit or loss following the derecognition of the equity instrument including on disposal; fair value gains and losses on equity instruments are reclassified on derecognition to Accumulated reserves within Shareholders’ equity in the consolidated balance sheet. The fair value gains and losses on equity instruments presented in other comprehensive income includes any related foreign exchange component. Dividends on these investments in equity instruments are recognized in profit or loss in accordance with IFRS 9, unless the dividends clearly represent a recovery of part of the cost of the investment. Dividends are included in Income from equity instruments in the consolidated income statement. As of December 31, 2020 and 2021, there were no significant investments in quoted financial instruments that had ceased to be recognized at their quoted price because their market could not be deemed to be active. Financial derivatives All financial derivatives are recognized in the consolidated balance sheet at fair value from the trade date. If the fair value is positive, they are recognized as an asset and if the fair value is negative, they are recognized as a liability. In the absence of evidence to the contrary, the fair value on the trade date is deemed to be the transaction price. The changes in the fair value of financial derivatives from the trade date are recognized in Gains/(losses) on financial assets and liabilities (net) in the consolidated income statement. Specifically, the fair value of financial derivatives traded in organized markets included in the portfolios of financial assets or liabilities held for trading is deemed to be their daily quoted price. If for exceptional reasons the quoted price cannot be determined on a given date, these financial derivatives are measured using methods similar to those used to measure “over-the-counter” (OTC) financial derivatives. The fair value of OTC financial derivatives is determined using the most appropriate valuation techniques commonly used by the financial markets based on the characteristics of each financial instrument such as net present value, option pricing models and other methods. ii. Measurement of financial liabilities In general, financial liabilities are measured at amortized cost using the effective interest method, except for those included under Financial liabilities at fair value through profit or loss and financial liabilities designated as hedged items (or hedging instruments) in fair value hedges, which are measured at fair value. The effective interest method is a method of calculating the amortized cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments (including all fees and basis points paid or received that form an integral part of the effective interest rate, transaction costs and other premiums or discounts) through the expected life of the financial liability, or (where appropriate) a shorter period, to the amortized cost of a financial liability. iii. Valuation techniques The following table shows a summary of the fair values as of December 31, 2020 and 2021 of the financial assets and liabilities indicated below, classified based on the various measurement methods used by the Bank to determine their fair value: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 12/31/2020 ​ ​ 12/31/2021 ​ ​ Published ​ ​ Published ​ ​ ​ ​ ​ ​ Price ​ ​ ​ ​ ​ ​ ​ ​ Price ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quotations ​ ​ ​ ​ ​ ​ Quotations ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Markets – ​ ​ Internal ​ ​ ​ ​ ​ Markets – ​ ​ Internal ​ ​ ​ ​ ​ ​ ​ Level 1 ​ ​ Models ​ ​ Total ​ ​ Level 1 ​ ​ Models ​ ​ Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ASSETS: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial assets at fair value through profit or loss ​ ​ 178,165 ​ ​ 396,545 ​ ​ 574,710 ​ ​ 106,073 ​ ​ 255,542 ​ ​ 361,615 ​ Financial assets at fair value through other comprehensive income ​ ​ 257,963 ​ ​ 98,126 ​ ​ 356,089 ​ ​ 250,631 ​ ​ 145,198 ​ ​ 395,829 ​ Hedging derivatives ​ ​ — ​ ​ 8,306 ​ ​ 8,306 ​ ​ — ​ ​ 11,248 ​ ​ 11,248 ​ ​ ​ ​ 436,128 ​ ​ 502,977 ​ ​ 939,105 ​ ​ 356,704 ​ ​ 411,988 ​ ​ 768,692 ​ LIABILITIES: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities at fair value through profit or loss ​ ​ 15,338 ​ ​ 497,652 ​ ​ 512,990 ​ ​ 62,570 ​ ​ 288,847 ​ ​ 351,417 ​ Hedging derivatives ​ ​ — ​ ​ 19,078 ​ ​ 19,078 ​ ​ — ​ ​ 8,162 ​ ​ 8,162 ​ ​ ​ ​ 15,338 ​ ​ 516,730 ​ ​ 532,068 ​ ​ 62,570 ​ ​ 297,009 ​ ​ 359,579 ​ ​ The financial instruments at fair value determined based on published price quotations in active markets (Level 1) include government debt securities, private-sector debt securities, financial derivatives traded in organized markets, securitized assets, equity shares, short positions and fixed-income securities issued. In cases where price quotations cannot be observed, Bank’s Management makes its best estimate of the price that the market would set using its own internal models (valuation techniques). These internal models use data, based on observable market parameters as significant inputs (Level 2) and, in very specific cases, they use significant inputs not observable in market data (Level 3). The use of observable market data assumes that markets are efficient and therefore the data that is derived therefrom is representative. The best evidence of the fair value of a financial instrument on initial recognition is the transaction price, unless the fair value of the instrument can be obtained from other market transactions performed with the same or similar instruments, or can be measured by using a valuation technique in which the variables used include only observable market data, mainly interest rates. The objective of valuation techniques is to arrive at a fair value measurement that reflects the price that would be received to sell the financial asset or paid to transfer the financial liability in an orderly transaction between market participants at the measurement date. Still, other internal models use unobservable data as inputs. Examples of such unobservable inputs and assumptions are as follows: - Correlation: Historical correlation between equity prices and foreign exchange rates is assumed for valuing quanto and composite options. - Dividends: The estimation for the dividend used as inputs in the internal models is based on the dividend payments expected from the issuer companies. - Volatility of equity instruments: There is no liquid option market for certain long-term financial assets. For most Mexican underlying assets, the option market is for up to one year. - Interest rate curve for estimating the interest rate index known as the 91-day TIIE (Tasa de Interés Interbancaria de Equilibrio) 91-day 28-day - Long-term Mexican rate curve: There is no liquid market for estimating and discounting financial instruments with maturities equal or higher than 20 years. - Market credit spreads: For some counterparties there is no credit default swaps (CDS) market quotes from which it is possible to infer a credit spread curve, this aspect is common for most of the Mexican counterparties. When there is no credit default swaps quote, generic credit curves are used instead. These curves are inferred from a proxy of quoted market credit default swaps considering geography, sector and rating. Whenever unobservable market data is used in valuation techniques, the valuation is adjusted considering unobservable assumptions that market participants would use when pricing the asset or liability, including assumptions about risk. The Bank also adjusts the value of some financial assets when they have very low market trading volume, even when prices are available. Fair value measurements that incorporate significant unobservable inputs are classified as Level 3. Significant unobservable inputs are defined as inputs for which observable market data are not available and that are significant to the fair value measurement. Such inputs are developed using the best information available about assumptions that market participants would use when pricing the asset or liability. iv. Valuation of financial instruments General measurement bases The Bank has implemented a formal process for systematic valuation and management of financial instruments. The governance scheme for this process distributes responsibilities between two independent areas inside the Bank: Treasury (development, marketing and daily management of financial products and market data) and Risks (on a periodic basis, validation of pricing and valuation models and market data, computation of risk metrics, new transactions approval policies, management of market risk and implementation of fair value adjustment policies). The approval of new products follows a sequence of steps (request, development, validation, integration in systems and quality assurance) before the product is ready to be placed on the market. This process ensures that pricing systems have been properly reviewed and are stable before they are used. The related valuation techniques and inputs by asset class are as follows: a. Financial assets at FVTPL and at FVTOCI The estimated fair value of these financial assets is determined using quoted prices or yield curves provided by the Bank´s pricing vendor. b. Loans and advances to credit institutions and customers – reverse repurchase agreements The fair value is estimated by using the discounted cash flow (forward estimation) technique using the interest rates that are currently offered for loans and advances with terms similar to those of borrowers having a similar credit quality. c. Loans and advances to customers at fair value through other comprehensive income The estimated fair value of these financial assets is calculated by a default estimation method. This method consists of: a) estimating the default probabilities through a bootstrapping method from market credit spreads to incorporate the credit risk in the risk interest rate and b) discounting the expected cash flow at risk interest rate through the applicable discount factor. Both steps use observable market data (yield curves and market credit spreads) which are provided by a price vendor. The model assumes a deterministic approximation for modelling the cancellation prepayment; it is assumed that the obligor has a rational behavior and will exercise at the best moment, and then it assumes that the cancellation will be total. d. Short positions, deposits from the Central Bank and deposits from credit institutions and customers – repurchase agreements The fair value of these financial instruments is calculated by using the discounted cash flow (forward estimation) technique based on the current incremental lending rates for similar types of deposits having similar maturities. e. Financial derivatives (assets and liabilities) The estimated fair value of futures contracts is calculated using the prices quoted on the Derivatives Exchange Markets ( Mercado Mexicano de Derivados If there are no quoted prices on the market (either direct or indirect) for a financial derivative instrument, the respective fair value estimates are calculated by using one of the following models and valuation techniques: i. In the valuation of financial instruments permitting static hedging (such as loans and advances to customers, deposits, forwards and swaps), the present value method (forward estimation) is used. This method consists of a) calculating the expected cash flows and b) discounting the expected cash flows at the risk interest rate through the applicable discount factor. Both steps use observable market data (yield curves, foreign exchange spot rates and so forth) which are provided by a market data supplier (price vendor). ii. - The Black-Scholes model and Black model are used for the valuation of plain vanilla options, the first for foreign exchange and securities and the latter for interest rates. These models assume that the underlying price follows a lognormal distribution. - The Montecarlo method with the local volatility model is the market proxy or reference model to price a wider range of exotic equity products. - The partial differential equation method with the local volatility model is particularly appropriate to price and manage callable products and products including barrier features on a single underlying. This method is quicker, more stable and more precise than the standard Montecarlo method, but the latter is needed when the underlying is a basket. The local volatility models assume that share and index prices are log normally distributed and volatility is a deterministic function of time and the market price. - The trinomial trees method is intended for American foreign exchange products, which can be canceled at any time throughout the life of the option. It assumes deterministic interest rates and represents the evolution of the underlying foreign exchange using the Black-Scholes model. - The partial differential equation solver using a mixed volatility model is used for pricing barrier products in foreign exchange. The development of a mixed volatility model was motivated by some very sensitive barrier products (double-no-touch options), which were quoted in the market with prices in between those provided by a local volatility model and a pure stochastic volatility model. The mixed volatility model is a combination of both models, which provides a price between them. f. Marketable debt securities The fair value of these financial instruments is calculated by using the discounted cash flow (forward estimation) technique, based on the current incremental lending rates for similar types of deposits having similar maturities, for the debt obligation component and one of the financial derivatives valuation techniques for the embedded derivative component, which depends on the payoff. Valuation adjustment for counterparty risk or default risk The Credit Valuation Adjustment (CVA) is a valuation adjustment to OTC financial derivatives because of the risk associated with the credit exposure assumed with each counterparty. The CVA is calculated taking into account potential exposure with each counterparty in each future period. The CVA for a specific counterparty is equal to the sum of the CVA for all the periods. The following inputs are used to calculate the CVA: ● Expected exposure: mark-to-market (MtM) value for each transaction plus an add-on for the potential future exposure for each period. Mitigating factors such as collateral and netting agreements are taken into account, as well as a temporary impairment factor for financial derivatives with interim payments. ● Loss Given Default: percentage of final loss assumed in a counterparty credit event /default. ● Probability of Default: for cases where there is no market information, such as the CDS quoted spread curve, proxies based on companies holding exchange-listed CDS, in the same industry and with the same external ratings as the counterparty, are used. ● Discount factor curve. The Debt Valuation Adjustment (DVA) is a valuation adjustment similar to the CVA but, in this case, it arises because of the Bank’s own credit risk assumed by its counterparties in OTC financial derivatives. The CVA and DVA recognized as of December 31, 2020 amounted to 328 million pesos and 1,365 million pesos, respectively. The CVA and DVA recognized as of December 31, 2021 amounted to 146 million pesos and 933 million pesos, respectively. All financial instruments fair values are calculated on a daily basis. Set forth below are the financial instruments at fair value which measurement was based on internal models (Level 2 and Level 3) as of December 31, 2020 and 2021. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Fair ​ ​ ​ ​ Values Values ​ ​ ​ ​ Calculated Calculated ​ ​ ​ ​ Using Internal Using Internal Valuation Techniques Key Inputs ​ ​ Models as of Models as of ​ ​ ​ ​ 12/31/2020 12/31/2021 ​ ​ ​ Level 2 Level 3 Total Level 2 Level 3 Total ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ASSETS: ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial assets at fair value through profit or loss: 395,923 622 396,545 255,403 139 255,542 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans and advances to credit institutions – Reverse repurchase agreements ​ 59,512 — 59,512 58,486 — 58,486 Forward estimation (non-closed formula) Interest rate yield curve ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans and advances to customers – Reverse repurchase agreements ​ 10,844 — 10,844 10,000 — 10,000 Forward estimation (non-closed formula) Interest rate yield curve ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debt and equity instruments 30,019 — 30,019 49,404 — 49,404 Price vendor Financial instruments with low trading volume or minimum marketability.

Derecognition of financial assets and liabilities	e) Derecognition of financial assets and liabilities The accounting treatment of transfers of financial assets depends on the extent to which the risks and rewards associated with the transferred assets are transferred to third parties: 1. If the Bank transfers substantially all the risks and rewards to third parties – unconditional sale of financial assets, sale of financial assets under an agreement to repurchase them at their fair value at the date of repurchase, sale of financial assets with a purchased call option or written put option that is deeply out of the money, securitization of assets in which the transferor does not retain a subordinated debt or grant any credit enhancement to the new holders, and other similar cases – the transferred financial asset is derecognized and any rights or obligations retained or created in the transfer are recognized simultaneously. 2. If the Bank retains substantially all the risks and rewards associated with the transferred financial asset – sale of financial assets under an agreement to repurchase them at a fixed price or at the sale price plus interest, a securities lending agreement in which the borrower undertakes to return the same or similar assets, and other similar cases – the transferred financial asset is not derecognized and continues to be measured by the same criteria as those used before the transfer. However, the following items are recognized: a. An associated financial liability, which is recognized for an amount equal to the consideration received and is subsequently measured at amortized cost. b. The income from the transferred financial asset not derecognized and any expense incurred on the new financial liability, without offsetting. 3. If the Bank neither transfers nor retains substantially all the risks and rewards associated with the transferred financial asset – sale of financial assets with a purchased call option or written put option that is not deeply in or out of the money, securitization of assets in which the transferor retains a subordinated debt or other type of credit enhancement for a portion of the transferred asset, and other similar cases – the following distinction is made: a. If the transferor does not retain control of the transferred financial asset, the asset is derecognized and any rights or obligations retained or created in the transfer are recognized. b. If the transferor retains control of the transferred financial asset, it continues to recognize it for an amount equal to its exposure to changes in value and recognizes a financial liability associated with the transferred financial asset. The net carrying amount of the transferred asset and the associated liability is the amortized cost of the rights and obligations retained, if the transferred asset is measured at amortized cost, or the fair value of the rights and obligations retained, if the transferred asset is measured at fair value. Accordingly, financial assets are only derecognized when the rights to the cash flows they generate have expired or when substantially all the inherent risks and rewards have been transferred to third parties. Financial liabilities are only derecognized when the obligations they generate have been extinguished, that is when the contractual obligations have been paid or cancelled, or have been expired. The exchange between the Bank and its original lenders of debt instruments with substantially different terms, as well as substantial modifications of the terms of existing financial liabilities, are accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. The terms are substantially different if the discounted present value of the cash flows under the new terms, including any fees paid net of any fees received and discounted using the original effective interest rate, is at least 10% different from the discounted present value of the remaining cash flows of the original financial liability, both discounted at the original effective interest rate of the original liability. In addition, other qualitative factors, such as the currency that the instrument is denominated in, changes in the type of interest rate, new conversion features attached to the instrument and change in covenants are also taken into consideration. If an exchange of debt instruments or modification of terms is accounted for an extinguishment, any costs of fees incurred are recognized as part of the gain or loss on the extinguishment. If the exchange or modification is not accounted for as an extinguishment, any costs or fees incurred adjust the carrying amount of the liability and are amortized over the remaining term of the modified liability.
Offsetting of financial instruments	f) Offsetting of financial instruments Financial asset and liability balances are offset, i.e., reported in the consolidated balance sheet at their net amount, only if the Bank currently have a legally enforceable right to set-off the recognized amounts and intend either to settle on a net basis or to realize the asset and settle the liability simultaneously. The disclosures set out in the tables below include financial assets and financial liabilities that: ● Are offset in the consolidated balance sheet; or ● Are subject to an enforceable master netting arrangement or similar agreement that covers similar financial instruments, irrespective of whether they are offset in the consolidated balance sheet. The similar agreements include financial derivative clearing agreements, global master repurchase agreements and global master securities lending agreements. Similar financial instruments include financial derivatives, repurchase agreements, reverse repurchase agreements, securities borrowing and lending agreements. Financial instruments such as loans and advances to customers and deposits are not disclosed in the tables below unless they are offset in the consolidated balance sheet. Financial derivative transactions are either transacted on an exchange or entered into under ISDA master netting agreements. In general, under ISDA master netting agreements in certain circumstances (e.g. when a credit event such as a default occurs) all outstanding transactions under the agreement are terminated. The termination value is assessed and only a single net amount is due or payable in settlement of all transactions. Repurchase agreements, reverse repurchase agreements, securities borrowing and lending agreements are covered by master agreements with netting terms similar to those of ISDA master netting agreements. The ISDA and similar master netting arrangements do not meet the criteria for offsetting in the consolidated balance sheet. This is because they create for the parties to the agreement a right of set-off of recognized amounts that is enforceable only following an event of default, insolvency or bankruptcy of the Bank or the counterparties or following other predetermined events. In addition, the Bank does not intend to settle on a net basis or to realize the financial assets and settle the financial liabilities simultaneously. The Bank receives and gives collateral in the form of cash and debt securities in connection with the following transactions: ● Financial derivatives; ● Repurchase agreements and reverse repurchase agreements; and ● Securities lending and borrowing agreements. Such collateral is subject to standard industry terms including, when appropriate, an ISDA Credit Support Annex (CSA). This means that securities received/given as collateral can be pledged or sold during the term of the transaction but have to be returned on maturity of the transaction. The terms also give each party the right to terminate the related transactions on the counterparty’s failure to post collateral. The following financial assets are subject to offsetting, enforceable master netting arrangements and similar agreements: As of December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount not offset in the consolidated balance sheet ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross amount of ​ ​ Net amount of ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ financial liabilities ​ ​ financial assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ offset in the ​ ​ presented in the ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross amount of ​ ​ consolidated balance ​ ​ consolidated ​ ​ Impact of master ​ ​ Financial instrument ​ ​ Cash ​ ​ Net ​ ​ financial assets sheet balance sheet netting agreements collateral collateral amount ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial derivatives assets ​ 190,638 ​ — ​ 190,638 ​ (152,313) ​ (4,491) ​ (26,894) ​ 6,940 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Reverse repurchase agreements ​ ​ 68,486 ​ ​ — ​ ​ 68,486 ​ ​ (4,799) ​ ​ (63,687) ​ ​ — ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity instruments (*) (see Note 9.a) ​ ​ 9 ​ ​ — ​ ​ 9 ​ ​ — ​ ​ (74) ​ ​ — ​ ​ (65) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total ​ 259,133 ​ — ​ 259,133 ​ (157,112) ​ (68,252) ​ (26,894) ​ 6,875 ​ As of December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amount not offset in the consolidated balance sheet ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross amount of ​ ​ Net amount of ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ financial liabilities ​ ​ financial assets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ offset in the ​ ​ presented in the ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross amount of ​ ​ consolidated balance ​ ​ consolidated ​ ​ Impact of master ​ ​ Financial instrument ​ Cash ​ ​ Net ​ ​ financial assets sheet balance sheet netting agreements collateral collateral amount ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial derivatives assets ​ 304,477 ​ — ​ 304,477 ​ (256,053) ​ (5,483) ​ (23,052) ​ 19,889 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Reverse repurchase agreements ​ 70,356 ​ — ​ 70,356 ​ (10,800) ​ (59,557) ​ — ​ (1) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity instruments (*) (see Note 9.a) ​ ​ 107 ​ ​ — ​ ​ 107 ​ ​ — ​ ​ (137) ​ ​ — ​ ​ (30) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total ​ 374,940 ​ — ​ 374,940 ​ (266,853) ​ (65,177) ​ (23,052) ​ 19,858 ​ (*) As of December 31, 2020 and 2021, the financial instruments received as collateral in lending transactions amount to 137 million pesos and 74 million pesos, respectively, which are limited to the net equities lent under the aforementioned lending transactions.

Impairment of financial assets	g) Impairment of financial assets Definition The Bank associates an impairment in the value to financial assets measured at amortized cost, financial assets at FVTOCI, lease receivables and loan commitments and guarantees granted that are not measured at fair value. The impairment represents the best estimation of the financial assets expected credit losses at the consolidated balance sheet date. The impairment for expected credit losses is recognized in the consolidated income statement for the period in which the impairment arises. In the event of occurrence, the recoveries of previously recognized impairment losses are recognized in the consolidated income statement for the period in which the impairment no longer exists or is reduced. In the case of POCI financial assets, the Bank only recognizes the changes in the expected credit losses during the life of the financial asset since the initial recognition as a credit loss. In the case of financial assets at FVTOCI, the changes in the fair value due to expected credit losses are recognized in the consolidated income statement of the year where the change happened, reflecting the rest of the valuation in other comprehensive income. The expected credit loss is estimated as the difference between the contractual cash flows to be recovered and the expected cash flows discounted using the original effective interest rate. In the case of POCI financial assets, this difference is discounted using the effective interest rate adjusted by credit rating. Allowance for impairment losses The Bank assesses on a forward-looking basis the expected credit losses associated with its financial assets carried at amortized cost and at FVTOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk. The impairment estimation methodology segregates financial assets in three categories, based on the stage of each financial asset with regard to its level of credit risk: ● Stage 1 (Normal risk): financial assets for which no significant increase in credit risk is identified since their initial recognition. In this case, the allowance for impairment losses reflects credit losses arising from expected defaults over the following twelve months from the reporting date. ● Stage 2 (Normal risk under watchlist): if there has been a significant increase in credit risk since the date of initial recognition but the impairment event has not materialized, the financial asset is classified as Stage 2. In this case, the allowance for impairment losses reflects the expected losses from expected defaults over the life of the financial asset. ● Stage 3 (Doubtful risk): a financial asset is classified in this stage when it shows effective signs of impairment as a result of one or more credit events that have already occurred resulting in a credit loss. In this case, the amount of the allowance for impairment losses reflects the expected losses for credit risk over the expected life of the financial asset. For POCI financial assets, the allowance for impairment losses reflects a deep discount that considers the incurred expected credit risk losses of the financial asset. Once the Bank has classified its financial assets according to the stage mentioned above, those financial assets are assessed for impairment individually or collectively in order to recognize the allowance for impairment losses arising from credit risk, as follows: Individual assessment Financial assets individually assessed for credit impairment are estimated by the following methodologies: a) Calculating the present value of expected cash flows discounted at an appropriate discount rate of those individually significant financial assets considering the debtor’s financial situation and any guarantees and collateral in place. The Bank takes into account all available information (external or internal), including expert judgment and reasonable and supportable forecasts of future events, to estimate the present value of expected cash flows, and b) Calculating the expected recovery from available collateral and guarantees, minus the estimated dispositions costs. Subsequently, expected cash flows, discounted at an appropriate rate, are estimated using the expected values from the sale or foreclosure of collateral and guarantees. The Bank takes into account all available information (external or internal), including expert judgment and reasonable and supportable forecasts of future events, to estimate the present value of expected cash flows. The Bank has defined as an “individually significant financial asset” those financial assets with a total current risk exposure amounting more than 8 million pesos for wholesale and small and medium-sized enterprises (SME) loan portfolio. This threshold is reviewed annually to adapt it to the Bank’s business circumstances. Collective assessment Financial assets collectively assessed for credit impairment are estimated by taking into consideration the historical impairment loss experience at the time of assessment adjusted to reflect current economic conditions and taking into account the characteristics of the counterparty, reasonable and supportable forecasts of future events, the guarantees and collateral associated with the transaction. In the estimation of the parameters used for the allowance for impairment losses and for provisions for off-balance sheet risk calculation such as Exposure at Default (EAD), Probability of Default (PD), Loss Given Default (LGD) and discount rate, the Bank leveraged on its experience developing internal models for calculating parameters for regulatory and management purposes. The Bank is aware of the differences between such internal models and IFRS 9 requirements for impairment purposes. As a result, it has focused on adapting to such requirements to the development of its IFRS 9 expected credit loss model. The Bank performs retrospective and monitoring tests to evaluate the reasonableness of the collective estimate. Grouping of financial assets for collective assessment Financial assets assessed collectively are grouped together considering those that have similar credit risk characteristics indicative of the debtors’ ability to pay all principal and interest amounts in accordance with the contractual terms. The credit risk characteristics considered for the purpose of grouping the financial assets are, inter alia, instrument type, debtor’s industry, type of guarantee or collateral, age of past due amounts and any other relevant factor for the estimation of future cash flows. In performing this grouping, there must be sufficient information for the group to be statistically credible. Where sufficient information is not available internally, the Bank has considered internal/external supplementary data to use for assessing purposes. The characteristics and any supplementary data used to determine groupings are outlined below: a) Middle-market corporate loans ● Credit rating band. ● Days past due. ● Product type. ● Vintage. ● Maturity. ● Guarantee or collateral. b) Mortgage loans ● Credit score. ● Time to maturity. ● Days past due. ● Vintage. ● Loan to value ratio band. ● Credit conversion from variable to fixed rate. c) Credit card loans ● Credit score. ● Days past due. ● Vintage. ● Available credit amount. ● Credit limit. ● Balance. d) Personal loans ● Credit score. ● Days past due. ● Product type. ● Vintage. ● Top-up susceptible. e) Small and medium-sized enterprises loans ● Credit score. ● Days past due. ● Balance. ● Vintage. ● Product type. ● Available credit amount. ● Credit limit. ● Guarantee from development banks. f) Payroll loans ● Credit score. ● Days past due. ● Granted amount. ● Balance. ● Percentage of granted amount. ● Vintage. ● Employer activity. The appropriateness of grouping is monitored and reviewed on a periodic basis. Significant increase in credit risk The Bank considers a financial asset to have experienced a significant increase in credit risk (SICR), since initial recognition, assigning a classification into Stage 2, when one or more of the following quantitative, qualitative or backstop criteria have been met: Quantitative criteria For commercial loans to small and medium-sized enterprises, mortgage loans and installment loans to individuals (revolving consumer credit card loans and non-revolving consumer loans), the Bank has established a comparison between the “Lifetime PD” at the reporting date and the “Remaining Lifetime PD Originated” when the financial asset was initially recognized. The financial assets are classified by the “Remaining Lifetime PD Originated” in bands. If the financial asset exceeds the predefined threshold for its band, it is classified as Stage 2 with the corresponding “Lifetime PD” at the reporting date. Each “Remaining Lifetime PD Originated” band classifies all the financial assets with similar characteristics of Probability of Default within a twelve-month period. In order to determine the applicable thresholds for each band, the Bank has analyzed the distribution of “Observed Default Frequency” within a twelve-month period in order to determine the threshold for each band where the defaults observed are concentrated. “Observed Default Frequency” is defined as the rate in which loans that were not impaired become credit-impaired in a lifetime period. The different bands of thresholds for each type of financial asset are shown below. Commercial loans to large enterprises ​ ​ ​ ​ ​ ​ “Lifetime PD” band at Increase in “Lifetime PD” at reporting date which ​ initial recognition (%) ​ ​ is considered significant (basis points) ​ ​ ​ ​ ​ <= 0.01178 ​ ​ 6 ​ 0.01178 - 0.01349 ​ ​ 16 ​ 0.01349 - 0.05377 ​ ​ 25 ​ > 0.05377 ​ ​ 35 ​ ​ ​ ​ ​ ​ Commercial loans to real state ​ ​ ​ ​ ​ ​ “Lifetime PD” band at Increase in “Lifetime PD” at reporting date which ​ initial recognition (%) ​ ​ is considered significant (basis points) ​ ​ ​ ​ ​ <= 0.00683 ​ ​ 4 ​ 0.00683 - 0.00944 ​ ​ 16 ​ > 0.00944 ​ ​ 27 ​ ​ ​ ​ ​ ​ Commercial loans to small and medium-sized enterprises ​ ​ ​ ​ ​ ​ “Lifetime PD” band at Increase in “Lifetime PD” at reporting date which ​ initial recognition (%) ​ ​ is considered significant (basis points) ​ ​ ​ ​ ​ <= 0.01660 ​ ​ 8 ​ 0.01660 - 0.02135 ​ ​ 13 ​ 0.02135 - 0.03718 ​ ​ 15 ​ 0.03718 - 0.06932 ​ ​ 16 ​ 0.06932 - 0.11089 ​ ​ 21 ​ 0.11089 - 0.14153 ​ ​ 24 ​ 0.14153 - 0.16235 ​ ​ 28 ​ 0.16235 - 0.25103 ​ ​ 29 ​ > 0.25103 ​ ​ 31 ​ ​ ​ ​ ​ ​ Mortgage loans ​ ​ ​ ​ ​ ​ “Lifetime PD” band at Increase in “Lifetime PD” at reporting date which ​ initial recognition (%) ​ ​ is considered significant (basis points) ​ ​ ​ ​ ​ <= 0.04077 ​ ​ 11 ​ 0.04077 - 0.05573 ​ ​ 14 ​ 0.05573 - 0.06676 ​ ​ 18 ​ 0.06676 - 0.12477 ​ ​ 20 ​ 0.12477 - 0.15225 ​ ​ 22 ​ > 0.15225 ​ ​ 24 ​ ​ ​ ​ ​ ​ Revolving consumer credit card loans ​ ​ ​ ​ ​ ​ “Lifetime PD” band at ​ ​ Increase in “Lifetime PD” at reporting date which ​ initial recognition (%) ​ ​ is considered significant (basis points) ​ ​ ​ ​ ​ <= 0.00953 ​ ​ 10 ​ 0.00953 - 0.01147 ​ ​ 11 ​ 0.01147 - 0.02353 ​ ​ 16 ​ 0.02353 - 0.02900 ​ ​ 23 ​ 0.02900 - 0.04120 ​ ​ 26 ​ 0.04120 - 0.05442 ​ ​ 30 ​ 0.05442 - 0.06950 ​ ​ 34 ​ > 0.06950 ​ ​ 38 ​ ​ ​ ​ ​ ​ Non-revolving consumer loans (payroll loans) ​ ​ ​ ​ ​ ​ “Lifetime PD” band at Increase in “Lifetime PD” at reporting date which ​ initial recognition (%) ​ ​ is considered significant (basis points) ​ ​ ​ ​ ​ <= 0.10109 ​ ​ 15 ​ 0.10109 - 0.13383 ​ ​ 22 ​ 0.13383 - 0.15909 ​ ​ 24 ​ 0.15909 - 0.19360 ​ ​ 25 ​ 0.19360 - 0.21380 ​ ​ 27 ​ 0.21380 - 0.24165 ​ ​ 29 ​ 0.24165 - 0.26122 ​ ​ 31 ​ > 0.26122 ​ ​ 32 ​ ​ ​ ​ ​ ​ Non-revolving consumer loans (personal loans) ​ ​ ​ ​ ​ ​ “Lifetime PD” band at Increase in “Lifetime PD” at reporting date which ​ initial recognition (%) ​ ​ is considered significant (basis points) ​ ​ ​ ​ ​ <= 0.14306 ​ ​ 16 ​ 0.14306 - 0.19274 ​ ​ 20 ​ 0.19274 - 0.24346 ​ ​ 24 ​ 0.24346 - 0.25868 ​ ​ 28 ​ 0.25868 - 0.28734 ​ ​ 31 ​ 0.28734 - 0.33463 ​ ​ 33 ​ > 0.33463 ​ ​ 36 ​ ​ ​ ​ ​ ​ The “Lifetime PD” movements on financial assets which do not subsequently become more than thirty days past due have also been assessed to identify the “natural” movement in “Lifetime PD” which is not considered indicative of a significant increase in credit risk. For Santander Corporate and Investment Banking customers, debt instruments at amortized cost and debt instruments at FVTOCI, the assessment is performed by comparing the current credit rating with the initial credit rating for each financial asset. Qualitative criteria For commercial loans to small and medium-sized enterprises, mortgage loans and installment loans to individuals (revolving consumer credit card loans and non-revolving consumer loans), if the borrower meets one or more of the following criteria: ● In short-term forbearance. ● Extension to the terms granted. For Santander Corporate and Investment Banking customers, debt instruments at amortized cost and debt instruments at FVTOCI, if the borrower requires closer monitoring and a review of its credit rating and/or the financial asset meets one or more of the following criteria: ● Significant debt instrument price variation. ● Significant adverse changes in business, financial and/or economic conditions in which the borrower operates. ● Actual or expected forbearance or restructuring. ● Actual or expected significant adverse change in operating results of the borrower. ● Significant change in collateral value, which is expected to increase risk of default. ● Early signs of cash flow/ liquidity problems. The assessment of significant increase in credit risk incorporates forward-looking information and is performed on a monthly basis at a portfolio level for all retail financial assets held by the Bank. For non-retail financial assets, where a “watchlist” is used to monitor credit risk, this assessment is performed at counterparty level on a periodic basis. The criteria used to identify the significant increase in credit risk are monitored and reviewed periodically for appropriateness by the Bank. The Bank does not consider the low credit risk as an indicator that a financial asset has not increased significantly in risk since initial recognition. Backstop criteria A backstop is applied and the financial asset is considered to have experienced a significant increase in credit risk if the borrower is more than thirty days past due on its contractual payments. Definition of default and credit-impaired financial assets The Bank defines a financial asset as in default, when the financial asset is considered as credit-impaired or non-performing. Credit-impaired loans or non-performing loans include customers, which are in financial difficulties and have been renegotiated. Credit-impaired financial assets are classified as Stage 3 category according to IFRS 9. The Bank applies the following criteria to classify financial assets as credit-impaired loans: ● Commercial, financial and industrial loans. Loans with a single payment of principal and interest (non-amortizing loans), generally commercial loans for a short period, are considered impaired after ninety days of the maturity date. Loans with a single payment of principal at maturity and with periodic interest payments (interest-only loans) are considered impaired after ninety days interest or principal become due. Loans whose principal and interest payments have been agreed in periodic installments (amortizing loans) are considered impaired after ninety days an installment becomes due. ● Mortgage loans. Mortgage loans are considered credit-impaired when a payment is past due more than ninety days. ● Installment loans to individuals. Revolving consumer credit cards loans are considered credit-impaired when payment is not received after ninety days it becomes due. Non-revolving consumer loans whose principal and interest payments have been agreed in periodic installments are considered impaired after ninety days an installment becomes due. ● If the borrower is declared bankrupt in accordance with the Mexican Commercial Bankruptcy Law. The Bank considers also as credit-impaired or non-performing financial assets, the sum of all transactions of a customer when the loan balances of the same customer categorized, as credit-impaired (Stage 3) are equivalent to more than 20% of the total outstanding amounts of that customer or when the recently twelve-month written-off balance of a customer represents more than 5% of such customer’s outstanding balance. These instruments may be reclassified to other categories if, because of the collection of part of the past due balances, the reasons for their classification in Stage 3 do not remain and the customer does not have balances more than ninety days past due in other loans. Loans which are not credit-impaired due to default but for which there are reasonable doubts about their full repayment (principal and interest) according to its contractual terms are considered credit-impaired. This analysis includes, among others: customers in situations involving deterioration in their creditworthiness, such as negative net equity, continued losses, significant decrease in revenue or in the customer’s recurring cash flows, general delay in payments, inadequate economic or financial structure, insufficient cash flows to settle debt or inability to obtain additional financing, the existence of an internal or external rating showing that the customer is in default and the existence of overdue customer commitments with a significant amount to public institutions or employees. These financial instruments may be reclassified to other categories if, as a result of an individualized study, reasonable doubts do not remain about the total repayment under the contractually agreed terms and the customer does not have balances with more than ninety days past due. Credit-impaired loans, which are renegotiated, will remain classified as Stage 3 category until there exists evidence of sustained payment. Sustained payment is considered as the payment by the borrower without payment delay for the total amount due and payable in terms of principal and interest during certain period. Loans are considered to be no longer in default (i.e., to have been cured) when all the contractual payments have been settled, except for those cases in which the borrower is in long-term forbearance and loan does not fulfill the criteria to be considered as credit-impaired. For these particular cases, a twelve-month probation period is necessary in order to be considered as not in default. In the case of forbearances, loans classified as Stage 2 (normal risk under watchlist) may be generally reclassified to Stage 1 (normal risk) in the following circumstances: i) at least two years have elapsed from the date of reclassification to that category or from its forbearance date, ii) the customer has paid the accrued principal and interest balance, and iii) the customer has no other instruments with more than thirty days past due balances. In the case of forbearances, loans classified as Stage 3 (doubtful risk) may be reclassified to Stage 2 (normal risk under watchlist) when the following circumstances are present: i) a minimum period of one year has elapsed from the forbearance date, ii) the customer has paid the accrued principal and interest amounts, and iii) the customer has no other loan balance with more than ninety days past due. Debt instruments are considered credit-impaired when a payment is past due more than ninety days. Measuring expected credit losses Measurement of expected credit losses (ECL) requires the use of complex models and significant assumptions about future economic conditions and credit behavior (i.e., the likelihood of customers defaulting and the resulting credit losses) and requires significant judgments that must be supported by past, present and future information, such as: ● Determining criteria for significant increase in credit risk. ● Choosing appropriate models and assumptions for the measurement of expected credit losses. ● Making assumptions and estimates to incorporate relevant information about past events, current conditions and forecasts of macroeconomic conditions. ● Determining the lifetime and point of initial recognition of revolving consumer credit card loans. ● Establishing the number and relative weightings of forward-looking scenarios. ● Establishing groups of similar financial assets for measuring expected credit losses. The methodology for the quantification of expected credit losses is based on an unbiased and weighted consideration of the occurrence of up to three possible future scenarios that could impact the collection of contractual cash flows, taking into account the time-value of money, all available information relevant to past events and current conditions and projections of certain portfolio factors and macroeconomic factors, such as GDP, Consumer Price Index (CPI), or unemployment rates, deemed relevant to the measurement of expected credit losses. Expected credit losses are recognized for financial assets measured at amortized cost, financial assets measured at FVTOCI, financial guarantees and loan commitments. Expected credit losses are also recognized on the undrawn portion of revolving credit lines, which include credit card limits. The expected credit losses are measured on either a twelve-month or “Lifetime” basis depending on whether a significant increase in credit risk has occurred since initial recognition or whether a financial asset is considered to be credit-impaired. Expected credit losses are the discounted product of the PD, EAD and LGD, defined as follows: ● The PD is the estimated probability that the counterparty will default on its principal and/or interest payment obligations. The PD has been defined as the probability that an operation accumulates more than ninety days past due or is deemed to be in default as per the criteria mentioned above, either over the next twelve months or over the remaining lifetime (Lifetime PD) of the obligation. ● EAD is the amount of estimated risk exposure incurred at the time of the counterparty’s analysis. ● LGD is the estimated loss arising in an event of default. It depends mainly on the guarantees and collateral associated with the transaction. LGD is expressed as a percentage loss per unit of exposure at the time of default (EAD). LGD is calculated on a twelve-month or “Lifetime” basis, where twelve-month LGD is the percentage of loss expected to be incurred if the default occurs in the next twelve months and “Lifetime” LGD is the percentage of loss expected to be incurred if the default occurs over the remaining expected lifetime of the loan. The expected credit losses are determined by projecting the PD, LGD and EAD for each future year and for each loan. These three components are multiplied together and adjusted for the likelihood of survival (i.e., the exposure has not prepaid or defaulted in an earlier month). This effectively calculates the expected credit losses for each future year, which is then discounted back to the reporting date and added. The discount rate used in the expected credit losses calculation is the original effective interest rate of the exposure or an approximation thereof. The “Lifetime PD” is developed by applying a maturity profile to the current twelve-month PD. The maturity profile looks at how defaults develop on a financial assets portfolio from the point of initial recognition throughout the lifetime of the financial assets. The maturity profile is based on historical observed data and is assumed to be the same across all financial assets within a portfolio. This is supported by historical analysis. The twelve-month EAD and “Lifetime” EAD are determined based on the expected payment profile, which varies by loan type. ● For amortizing products and bullet repayment loans, this is based on the contractual repayments owed by the borrower over a twelve-month or “Lifetime” basis. “Lifetime” EAD will also be adjusted for any expected overpayments made by a borrower. Early repayment/refinance assumptions are also incorporated into the “Lifetime” EAD calculation. ● For revolving consumer loans, the EAD is predicted by taking current drawn balance and adding a “Credit Conversion Factor” (CCF) which allows for the expected drawdown of the remaining limit by the time of default. These assumptions vary by loan type and current limit utilization band, based on analysis of the Bank´s recent historical default data. The twelve-month LGD and “Lifetime” LGD are determined based on the factors which impact the recoveries made post-default. These vary by loan type. ● For secured loans, this is primarily based on collateral type and projected collateral values, historical discounts to market/book values due to forced sales, time to repossession and recovery costs observed. ● For unsecured loans, LGD is typically set by loan due to the limited differentiation in recoveries archived across different borrowers. The LGD is influenced by collection strategies, including contracted debt sales and price. Forward-looking economic information is also included in determining the twelve-month PD, “Lifetime PD” and LGD. These assumptions vary by loan type. The assumptions underlying the expected credit losses calculation – such as how the maturity profile of the PD and how collateral values change – are monitored and reviewed on a monthly basis. The Bank performs a periodic assessment to evaluate if the assumptions and methodology need to be updated. The assessments performed during the year ended December 31, 2021 have not identified significant changes in facts and circumstances that would require updates on estimation techniques, significant assumptions or methodologies currently employed in the expected credit losses calculation. Expected credit loss measurement considerations related to COVID-19 pandemic Expected credit losses measurement according to IFRS 9 is challenging given its determination incorporates the estimation of credit events, and their consequential cash shortfalls, based on a probability - Expected credit losses are a discounted probability - The IASB had indicated that entities should not continue to apply their existing ECL methodology mechanically. IFRS 9 requires the application of judgment and requires and allows entities to adjust their approach to determining expected credit losses in different circumstances. The IASB noted that a number of assumptions and linkages underlying the way expected credit losses have been determined no longer hold due to the COVID-19 pandemic environment. Measurement of expected credit losses and assessment of a significant increase in credit risk are based on reasonable and supportable information that is available without undue cost or effort. Hence, the Bank developed its estimates based on the best available information about past events, current conditions and forecasts of economic conditions and applied certain key IFRS 9 accounting considerations related to the measurement of expected credit losses with the purpose of capturing the effects of the COVID - The current environment is subject to rapid change, so the Bank continuously monitors updated facts and circumstances as new information becomes available. IFRS 9 is purposefully designed to be forward-looking, reflecting expectations of future credit events (and resulting cash shortfalls) assessed at the reporting date. Although current circumstances are difficult and create high levels of uncertainty, the expected credit losses estimated by the Bank as of December 31, 2021 are based on all reasonable and supportable information including that, which is forward-looking. The Bank updated the following forward-looking information in the measurement of the expected credit losses due to the COVID-19 pandemic situation: ● Macroeconomic forecasts including GDP, industry-sector growth rates, unemployment (national and regional), inflation, interest rates and property price indexation. ● Customers’ probability of non-payment in response to macroeconomic factors that specifically relate to the customer, noting that customers may prioritize payments of some debt obligations over others and therefore the credit risk of amounts owed to different creditors by the same customer can vary. ● Customers’ behavior in respect of timing of prepayment or extension options, or use of undrawn facilities that affect Bank’s exposure. ● Valuation of collateral and timing of foreclosure. This forward - In applying IFRS 9, the Bank defined a number of key terms and made a number of important application decisions when measuring expected credit losses. One such item is the definition of default. The definition of default directly influences the staging of exposures given that staging is based on the probability of default happening. IFRS 9 requires that default definition is applied consistently to all financial instruments unless information becomes available that demonstrates that another default definition is more appropriate for a particular financial instrument to ensure that they reflect current economic conditions of what a default is. The Bank’s definition of default is aligned, to the extent acceptable, to prudential regulatory definitions of default. IFRS 9 states that there is a rebuttable presumption that default does not occur later than when a financial asset is ninety days past due unless there is reasonable and supportable information to demonstrate that a more lagging default criterion is more appropriate. In staging analysis, the Bank does not apply mechanically the identification of a significant increase in credit risk. Assessment of a significant increase in credit risk is based on reasonable and supportable information that is available without undue cost or effort. The Bank applied a medium-long term approach when assessing the customer’s credit quality and considers if the customer is experiencing temporary financial difficulties in order to determine the correspondent classification (staging). Repayment capacity of the customer in the medium-term is also evaluated. The Bank monitors the behavior of ratings and in case of atypical movements; implements actions in order to avoid an excessive impact on the expected credit losses. Post-model adjustments - overlays During 2020, the Bank decided to recognize a “macroeconomic overlay”, which was calculated with a long-run vision in order to avoid short-term volatility, which was determined from a softening of the macroeconomic scenario that the Bank uses in its annual planning exercise with a three-year horizon. This “macroeconomic overlay” was calculated under a bottom-up approach, aligned with the ‘business as usual’ (BAU) process of forward-looking calculation, where the sensitivity resulting from the expected credit losses, at a credit level, is distributed for each of the loan portfolios. During the course of 2020 and 2021, the macroeconomic overlay was released as a result of the return to normality of the Mexican economy. Accordingly, there are no post-model adjustments as of December 31, 2021. Details of post-model adjustments for 2020 – overlays is presented in Note 11.d. Expected life of the financial assets For the purpose of estimating the expected life of the financial assets, all the contractual terms have been taken into account (i.e., prepayments, duration, purchase options, etc.), being the contractual period (including extension options) the maximum period considered to measure the expected credit losses. In the case of financial assets with an uncertain maturity period and a component of undrawn commitment (i.e., credit cards), the expected life is estimated through quantitative analyses to determine the period during which the entity is exposed to credit risk, also considering the effectiveness of management procedures that mitigate such exposure (e.g. the ability to unilaterally cancel such financial asset, etc.). Effective guarantees The following constitute effective guarantees: a) Mortgage guarantees on housing as long as they are first duly constituted and registered in favor of the Bank. The properties include: i. Buildings and building elements, distinguishing among: ● Houses; ● Offices, stores and multi-purpose premises; ● Rest of buildings such as non-multi-purpose premises and hotels. ii. Urban and developable ordered land. iii. Rest of properties that classify as: buildings and building elements under construction, such as property development in progress and halted development, and the rest of land types, such as rural lands. b) Collateral gu
Repurchase agreements and reverse repurchase agreements	h) Repurchase agreements and Reverse repurchase agreements Purchases of financial instruments under a non-optional resale agreement at a fixed price are measured at fair value and recognized as assets in the consolidated balance sheet under Loans and advances to credit institutions – Reverse repurchase agreements or Loans and advances to customers – Reverse repurchase agreements. The excess of the purchase prices over the resale prices are recognized as interest income over the contract term. Sales of financial instruments under a non-optional repurchase agreement at a fixed price are measured at amortized cost or at fair value and recognized as liabilities in the consolidated balance sheet under Deposits from the Central Bank – Repurchase agreements, Deposits from credit institutions – Repurchase agreements or Customer deposits – Repurchase agreements. The excess of the sales prices over the repurchase prices are recognized as interest expense over the contract term. Repurchase agreements and reverse repurchase agreements are managed and its performance is evaluated on a fair value basis. As of December 31, 2021, in order to provide a better presentation, the Bank decided to present repurchase agreements and reverse repurchase agreement as financial liabilities at fair value through profit or loss (Deposits from Central Bank – Repurchase agreements, Deposits from credit institutions – Repurchase agreements and Customer deposits – Repurchase agreements) and as financial assets at fair value through profit or loss (Loans and advances to credit institutions – Reverse repurchase agreements and Loans and advances to customers – Reverse repurchase agreements) in the consolidated balance sheet and consolidated statements of cash flows.
Non-current assets held for sale	i) Non-current assets held for sale Non-current assets held for sale include the carrying amount of individual items, disposal groups or items forming part of a business unit earmarked for disposal (discontinued operations), whose sale is highly likely to be completed within one year from the reporting date. Therefore, the recovery of the carrying amount of these items will foreseeably be effected through the proceeds from their disposal. Specifically, property or other non-current assets (foreclosed assets) received by the Bank as total or partial settlement of their debtors’ payment obligations to them are deemed to be non-current assets held for sale, unless the Bank has decided to make continuing use of these assets. Liabilities associated with non-current assets held for sale include the balances payable arising from the assets held for sale or disposal groups and from discontinued operations. Non-current assets held for sale are measured at the lower of fair value less costs to sell and their carrying amount at the date of classification in this category. Non-current assets held for sale are not depreciated as long as they remain in this category. Impairment losses on an asset or disposal group arising from a reduction in its carrying amount to its fair value (less costs to sell) are recognized under Gains/(losses) on disposal of non-current assets held for sale not classified as discontinued operations (net) in the consolidated income statement. The gains on a non-current asset held for sale resulting from subsequent increases in fair value (less costs to sell) increase its carrying amount and are recognized in the consolidated income statement up to an amount equal to the impairment losses previously recognized.
Tangible assets	j) Tangible assets Tangible assets include the amount of buildings for own use, information technology (IT) equipment and fixtures, furniture and vehicles and other fixtures owned by the Bank. Tangible assets are presented at acquisition cost, less the related accumulated depreciation and any estimated impairment losses (excess of carrying amount over the recoverable amount). Depreciation is calculated using the straight-line method based on the acquisition cost of the tangible assets less their residual value. The land on which the buildings stand has an indefinite life and therefore is not depreciated. Depreciation is recognized in the consolidated income statement and is calculated using the following depreciation rates (based on the average years of estimated useful life of the various assets): ​ ​ ​ ​ ​ ​ ​ Average Annual ​ ​ ​ ​ Rate ​ ​ ​ ​ ​ ​ Buildings for own use ​ 2% to 5% ​ Furniture and vehicles ​ 10% to 20% ​ Information technology equipment and fixtures ​ 25% ​ Other fixtures ​ 5% to 20% ​ ​ The Bank assesses at the reporting date whether there is any indication that a tangible asset may be impaired (i.e., its carrying amount exceeds its recoverable amount). If this is the case, the carrying amount of the tangible asset is reduced to its recoverable amount and future depreciation charges are adjusted in proportion to the revised carrying amount and to the new remaining useful life (if the useful life has to be re-estimated). Similarly, if there is an indication of a recovery in the value of a tangible asset, the Bank recognizes the reversal of the impairment loss recognized in prior periods and adjusts the future depreciation charges accordingly. In no circumstances may the reversal of an impairment loss on a tangible asset raise its carrying amount above that which it would have if no impairment losses had been recognized in prior years. The estimated useful lives of the tangible assets are reviewed at least at the end of the reporting period to identify significant changes therein. If changes are identified, the useful lives of the tangible assets are adjusted by correcting the depreciation charge to be recognized in the consolidated income statement in future years based on the new useful lives. Upkeep and maintenance expenses relating to the tangible assets are recognized as an expense in the period in which they are incurred, since they do not increase the useful lives of the assets. Tangible assets are derecognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. The gain or loss arising on the disposal or retirement of an asset is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognized in the consolidated income statement.
Leases	k) Leases The Bank as lessee The Bank assesses whether a contract is or contains a lease, at inception of the contract. The Bank recognizes a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee. Initially, the right-of-use asset is measured at cost, which comprises the amount of the lease liability, adjusted for any lease payment made in or before the commencement date less any lease incentives received, plus any other initial direct costs incurred by the lessee and an estimate of the costs for dismantling the underlying asset or for restoring the underlying asset or the site of its location. Right-of-use assets are valued at cost, which includes the following: ● ● ● ● Subsequently, the right-of-use asset is depreciated on the straight-line method from the commencement date to the lesser of the end of the useful life of the right-of-use asset or the end of the lease term. The estimate of the useful lives of the right-of-use asset is determined on the same bases as the assets. In addition, right-of-use asset is reduced for impairment, if any, and adjusted for the remeasurement of the lease liability. The Bank applies IAS 36 to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss. The right-of-use assets are presented as a separate line in the consolidated balance sheet. The lease liability is initially measured at the present value of the lease payments that have not been paid as of the commencement date, discounted at the rate implicit in the lease if that can be readily determined. If that rate cannot be readily determined, the lessee shall use the incremental borrowing rate. Subsequently, the lease liability is measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. Lease payments included in the measurement of the lease liability comprise the following: ● Fixed payments, including in-substance fixed payments, less any lease incentive receivable; ● Variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date. ● The amounts expected to be paid by the lessee under residual value guarantees; ● The exercise price of purchase options, if the lessee is reasonably certain to exercise that option; and ● Lease termination penalty payments, if the term of the lease reflects the lessee's exercise of that option. The lease liability is presented as a separate line in the consolidated balance sheet. The Bank remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use asset) whenever: ● The lease term has changed or there is a significant event or change in circumstances resulting in a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. ● The lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using an unchanged discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used). ● A lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured based on the lease term of the modified lease by discounting the revised lease payments using a revised discount rate at the effective date of the modification. The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, which is generally the case for leases in the Bank, the lessee’s incremental borrowing rate is used, being the rate that the Bank would have to pay to borrow the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment with similar terms, security and conditions. To determine the incremental borrowing rate, the Bank applies the Cross Section methodology, which consists of estimating the credit spread of the Bank based on the CDS information available from different entities. Under the Cross Section methodology, the following factors are considered to obtain the Bank’s credit spread: ● Economic sector, ● Geographical area, ● Rating, and ● An assumption to represent that at least one factor described above, match with the factors related to the Bank. Lease payments are allocated between principal and finance cost. The finance cost is recognized under Interest expense and other charges in the consolidated income statement over the lease period to produce a constant periodic rate of interest on the remaining balance of the liability for each period. Payments associated with short-term leases or low-value assets are recognized on a straight-line basis as an expense under Administrative expenses in the consolidated income statement. Short-term leases are leases with a lease term of twelve months or less. Low-value assets comprise, for example, personal computers, printers, small items of office furniture, telephones and other similar assets. Whenever the Bank incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognized and measured under IAS 37 Provisions, Contingent Liabilities and Contingent Assets . To the extent that the costs relate to a right-of-use asset, the costs are included in the related right-of-use assets. As of December 31, 2020 and 2021, the Bank did not have any lease agreements with purchase options. The Bank as lessor - Finance leases A lessor shall classify each of its leases as either an operating lease or a finance lease. A lease is classified as a finance lease if it transfers substantially all the risks and rewards incidental to ownership of an underlying asset. A lease is classified as an operating lease if it does not transfer substantially all the risks and rewards incidental to ownership of an underlying asset. Whether a lease is a finance lease or an operating lease depends on the substance of the transaction rather than the form of the contract. At the commencement date of the lease, the assets held by the Bank under a finance lease are recognized as Financial assets at amortized cost in the consolidated balance sheet at an amount equal to the net investment in the lease. The net investment in the lease corresponds to the gross investment in the lease discounted at the interest rate implicit in the lease. The gross investment in the lease is the sum of: (a) the lease payments receivable by a lessor under a finance lease; and (b) any unguaranteed residual value accruing to the lessor. IFRS 16 defines the interest rate implicit in the lease as the rate of interest that causes the present value of (a) the lease payments and (b) the unguaranteed residual value to equal the sum of (i) the fair value of the underlying asset and (ii) any initial direct costs of the lessor. The Bank recognizes finance income over the lease term in interest income calculated using the effective interest method in the consolidated income statement, based on a pattern reflecting a constant periodic rate of return on the lessor’s net investment in the lease.
Intangible assets	l) Intangible assets Intangible assets are identifiable non-monetary assets (separable from other assets) without physical substance which arise because of a legal transaction or which are developed internally by the Bank. Only assets whose cost can be estimated reliably and from which the Bank considers it probable that future economic benefits will be generated are recognized. Intangible assets are recognized initially at acquisition or development cost and are subsequently measured at cost less any accumulated amortization and any accumulated impairment losses. i. Goodwill Any excess of the cost of the investments made by the Bank over the corresponding underlying carrying amounts acquired, adjusted at the acquisition date, is allocated as follows: - If it is attributable to specific and identifiable assets and liabilities of the subsidiaries acquired, by increasing the value of the assets (or reducing the value of the liabilities) whose fair values were higher (lower) than the carrying amounts at which they had been recognized in the acquired subsidiaries’ balance sheets. - If it is attributable to specific intangible assets, by recognizing such intangible assets in the consolidated balance sheet if the fair value of these assets within twelve months following the date of acquisition can be measured reliably. - The remaining amount is recognized as goodwill, which is allocated to one or more CGU. A CGU is the smallest identifiable group of assets that, because of continuing operation, generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. Goodwill is only recognized when it has been acquired for a consideration and represents, therefore, a payment made by the acquirer in anticipation of future economic benefits from assets of the acquired subsidiary that are not capable of being individually identified and separately recognized. At the end of each reporting period, or whenever there is any indication of impairment, goodwill is reviewed for impairment (i.e., a reduction in its recoverable amount to below its carrying amount) and if there is any impairment, the goodwill is written down with a charge to the consolidated income statement. For the purposes of the impairment analysis, goodwill is allocated to one or more CGU expected to benefit from the synergies arising from business combinations. Each CGU to which goodwill is allocated: - is the lowest level at which the entity manages goodwill internally; and - is not larger than an operating segment. The CGU to which goodwill has been allocated are tested for impairment by including the allocated goodwill in their carrying amount. This analysis is performed at least annually as of December 31 and more frequently in cases where Bank’s Management notes indicators of impairment. For determining the impairment of a CGU to which a part of goodwill has been allocated, the carrying amount of that unit is compared with its recoverable amount. The recoverable amount of a CGU is equal to the higher of the fair value less costs to sell and its value in use. Value in use is calculated as the discounted value of the cash flow projections that the Bank estimates and is based on the latest budgets approved for the next five years. The principal hypotheses are a sustainable growth rate to extrapolate the cash flows indefinitely, and the discount rate used to discount the cash flows is equal to the weighted cost of capital assigned to each CGU. If the carrying amount of the CGU exceeds the related recoverable amount, the Bank recognizes an impairment loss; the resulting loss is apportioned by reducing, first, the carrying amount of the goodwill allocated to that CGU and, second, if there are still impairment losses remaining to be recognized, the carrying amount of the rest of the assets. This is done by allocating the remaining loss in proportion to the carrying amount of each of the assets in the unit. No impairment of goodwill attributable to the minority interests may be recognized. Impairment losses on goodwill are recognized under Impairment losses on other assets (net) - Goodwill and other intangible assets in the consolidated income statement. An impairment loss recognized for goodwill is not reversed in a subsequent period. ii. Other intangible assets Other intangible assets include the amount of identifiable intangible assets (such as computer software). Other intangible assets can have an indefinite useful life when, based on an analysis of all the relevant factors, it is concluded that there is no foreseeable limit to the period over which the asset is expected to generate net cash inflows for the Bank - or a finite useful life, in all other cases. Intangible assets with indefinite useful lives are not amortized and are carried at cost less accumulated impairment losses. At the end of each reporting period or whenever there is any indication of impairment, the Bank reviews the remaining useful lives of the assets in order to determine whether they continue to be indefinite and, if this is not the case, to take the appropriate steps. Intangible assets with finite useful lives are carried at cost less accumulated amortization and accumulated impairment losses. Amortization is recognized on a straight-line basis over their estimated useful lives. The estimated useful lives are reviewed at the end of each reporting period, with the effect of any changes in estimate being accounted for on a prospective basis. The intangible asset amortization charge is recognized under Depreciation and amortization in the consolidated income statement. Intangible assets acquired in a business combination and recognized separately from goodwill are initially recognized at their fair value at the acquisition date (which is regarded as their cost). Subsequent to initial recognition, intangible assets acquired in a business combination are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. An intangible asset is derecognized on disposal, or when no future economic benefits are expected from use or disposal. Gains or losses arising from derecognition of an intangible asset, measured as the difference between the net disposal proceeds and the carrying amount of the asset, are recognized in the consolidated income statement when the asset is derecognized. Impairment charges are included in Impairment losses on other assets (net) – Goodwill and other intangible assets in the consolidated income statement. The criteria used to recognize the impairment losses on these assets and, where applicable, the reversal of impairment losses recognized in prior years, are similar to those used for tangible assets (see Note 2.j). ​ Internally-generated computer software Expenditure on research activities is recognized as an expense in the period in which it is incurred. Development costs that are directly attributable to the design and testing of identifiable and unique software products controlled by the Bank are recognized as intangible assets when the following criteria are met: ● it is technically feasible to complete the software so that it will be available for use, ● Bank’s Management intends to complete the software and use or sell it, ● there is an ability to use or sell the software, ● it can be demonstrated how the software will generate probable future economic benefits, ● adequate technical, financial and other resources to complete the development and to use or sell the software are available, and ● the expenditure attributable to the software during its development can be reliably measured. Directly attributable costs that are capitalized as part of the software include employee costs and an appropriate portion of relevant overheads. Capitalized development costs are recognized as intangible assets and amortized from the point at which the asset is ready for use. Where no internally-generated computer software can be recognized, development expenditure is recognized in the consolidated income statement in the period in which it is incurred and cannot be subsequently capitalized. Subsequent to initial recognition, internally-generated computer software are reported at cost less accumulated amortization and accumulated impairment losses, on the same basis as intangible assets that are acquired separately.
Provisions and contingent assets and liabilities	m) Provisions and contingent assets and liabilities When preparing the consolidated financial statements, Bank’s Management distinguishes between: - Provisions: credit balances covering present obligations at the reporting date arising from past events, which could give rise to a loss for the Bank, which is considered to be likely to occur and certain as to its nature but uncertain as to its amount and/or timing. - Contingent liabilities: possible obligations that arise from past events and whose existence will be confirmed only by the occurrence or non-occurrence of one or more future events not wholly within the control of the Bank. They include the present obligations of the Bank when it is not probable that an outflow of resources embodying economic benefits will be required to settle them. The Bank does not recognize the contingent liability. The Bank will disclose a contingent liability, unless the possibility of an outflow of resources embodying economic benefits is remote. - Contingent assets: possible assets that arise from past events and whose existence is conditional on, and will be confirmed only by, the occurrence or non-occurrence of events beyond the control of the Bank. Contingent assets are not recognized in the consolidated balance sheet or in the consolidated income statement, but rather are disclosed in the notes to the consolidated financial statements, if it is probable that these assets will give rise to an increase in resources embodying economic benefits. Provisions Provisions are recognized when the Bank has a present obligation (legal or constructive) as a result of a past event, it is probable that the Bank will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the effect of the time value of money is material). When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognized as an asset if it is virtually certain that reimbursement will be received and the amount of the receivable can be measured reliably. The consolidated financial statements include all provisions with respect to which it is considered that it is more likely than not that the obligation will have to be settled. In accordance with IFRS, contingent liabilities must not be recognized in the consolidated financial statements, but must rather be disclosed in the notes to the consolidated financial statements. Provisions are reviewed and adjusted at the end of each year. Provisions are used also to cater for the specific obligations for which they were originally recognized. Provisions are reversed fully or partially when such obligations cease to exist or are reduced. Provisions are classified according to the obligations covered as follows: - Provisions for pensions and similar obligations under scope of IAS 19: amount of all the provisions made to cover post-employment benefits, including obligations to pre-retirees and similar obligations (see note 2.s). - Provisions for tax not included in the scope of IAS 12 and legal matters: amount of the provisions recognized to cover tax and legal obligations. - Provisions for off-balance sheet risk: amount of the provisions made to cover obligations arising as the result of those transactions in which the Bank guarantees the obligations of a third party arising as a result of financial guarantees granted or other contracts and unfunded lending commitments such as letters of credit, financial guarantees and available lines of credit cards and non-revolving consumer loans, which are irrevocable commitments that may give rise to the recognition of financial assets. - Other provisions: include the amount of other provisions recognized by the Bank (see Note 24).
Court proceedings and/or claims in process	n) Court proceedings and/or claims in process At the end of 2020 and 2021, certain court proceedings and claims were in process against the Bank arising from the ordinary course of their operations (see Note 24).
Share-based payments	o) Share-based payments Equity-settled shared-based payments to employees and others providing similar services were measured at the fair value of the equity instruments at the grant date. The fair value determined at the grant date of the equity-settled shared-based payments was expensed on a straight-line basis over the vesting period, based on the Bank’s estimate of equity instruments that would eventually vest, with a corresponding increase in consolidated total equity. At the end of each reporting period, the Bank revises its estimate of the number of equity instruments expected to vest. The impact of the revision of the original estimates, if any, is recognized in the consolidated income statement such that the cumulative expense reflects the revised estimate. Cash-settled share-based payments to employees, the services acquired and the liability incurred are measured at the fair value of the liability. The fair value determined at the grant date of the cash-settled share-based payments is expensed on a straight-line basis over the vesting period, based on the Bank’s estimate of equity instruments that will eventually vest, with a corresponding increase in the liability. At the end of each reporting period, the Bank revises its estimate of the number of equity instruments expected to vest. Until the liability is settled, the fair value of the liability is remeasured at the end of each reporting period and at the date of settlement, with any changes in fair value recognized in the consolidated income statement for the year. The services received and the liability to pay for those services are recognized as the employees render service. Share-based payments are discussed in Note 42.b, 42.c, 42.d and 43.b.
Recognition of income and expenses	p) Recognition of income and expense The most significant criteria used by the Bank to recognize its income and expenses are summarized as follows: i. Interest income and interest expense Interest income and interest expense are generally recognized on an accrual basis using the effective interest method. ii. Dividends Dividends received from equity instruments are recognized as income when the Bank’s right to receive them arises. iii. Fee and commission income and expense Fee and commission income and expense are recognized using criteria that vary according to their nature. The main criteria are as follows: - Fee and commission income and expense relating to financial assets and financial liabilities measured at FVTPL are recognized when received or paid. - Those arising from transactions or services that are performed over a period are recognized over the life of these transactions or services. - Those relating to services provided in a single act are recognized when the single act is carried out. iv. Non-finance income and expense Non-finance income and expense are recognized when the good is delivered or the non-financial service is rendered. To determine the amount and timing of recognition, IFRS 15 Revenue from Contracts with Customers v. Deferred collections and payments Deferred collections and payments are recognized at the amount resulting from discounting the expected cash flows at market rates. vi. Loan arrangement fees Loan arrangement fees that are an integral part of the effective interest rate of a financial instrument, mainly loan origination fees, are accrued and recognized over the term of the loan as a part of the effective interest method.
Financial guarantees	q) Financial guarantees Financial guarantees are defined as contracts whereby an entity undertakes to make specific payments on behalf of a third party if the latter fails to do so, irrespective of the various legal forms they may have, such as guarantees, insurance policies or credit derivatives. When the Bank purchases a financial guarantee contract in respect of a financial asset and pays the cost of the guarantee, at inception of the guarantee considers the following: - If the financial guarantee is an integral part of the guaranteed financial asset, it is treated as an adjustment to the effective interest rate of the guaranteed financial asset as a transaction cost, unless the financial asset is measured at FVTPL, and include the expected cash flows from the financial guarantee when measuring the expected credit losses of the guaranteed financial asset. - If the financial guarantee is not an integral part of the guaranteed financial asset, the cost is recognized as a separate pre-payment asset, and it is amortized over the shorter of the life of the guarantee and the expected life of the guaranteed financial asset. The pre-payment asset is tested for impairment under IAS 36. The expected cash flows from the financial guarantee are not included in the measurement of the expected credit losses of the guaranteed financial asset and a separate reimbursement asset is recognized in the consolidated balance sheet in accordance with IAS 37 . When the Bank provides financial guarantees, these are initially recognized on the liability side of the consolidated balance sheet at fair value, which is generally the present value of the fees, commissions and interest receivable from these contracts over the term thereof. Financial guarantee contracts issued by the Bank and, if not designated at FVTPL, are subsequently measured at the higher of: ● the amount of the obligation under the contract, as determined in accordance with the IFRS 9 expected credit loss model; and ● the amount initially recognized less, where appropriate, cumulative amortization recognized in accordance with the revenue recognition policies. Financial guarantees provided by the Bank, regardless of the guarantor, instrumentation or other circumstances are reviewed periodically to determine the credit risk to which they are exposed and, if appropriate, to consider whether a provision is required. The credit risk is determined by application of criteria similar to those established for quantifying impairment losses on financial assets carried at amortized cost (described in Note 2.g above). The provisions made for these transactions are recognized under Provisions – Other provisions in the consolidated balance sheet. These provisions are recognized and reversed with a charge or credit, respectively, to Provisions (net) in the consolidated income statement. If a specific provision is required for financial guarantees, the related unearned commissions recognized under Financial liabilities at amortized cost in the consolidated balance sheet are reclassified to the appropriate provision.
Loan commitments	r) Loan commitments Loan commitments granted by the Bank are subject to the impairment requirements of IFRS 9 and are accounted for as off-balance sheet risk in memorandum accounts. The provisions made for these transactions are recognized under Provisions for off-balance sheet risk in the consolidated balance sheet (see Note 24). These provisions are recognized and reversed with a charge or credit, respectively, to Provisions (net) in the consolidated income statement.
Post-employment benefits, Other long-term employee benefits and Termination benefits	s) Post-employment benefits The Bank’s post-employment obligations to its employees are deemed to be defined contribution plans when the Bank makes pre-determined contributions to a separate entity and will have no legal or effective obligation to make further contributions if the separate entity cannot pay the employee benefits relating to the service rendered in the current and prior periods. Post-employment obligations that do not meet the aforementioned conditions are classified as defined benefit plans (see Note 24.c). Defined contribution plans Payments made in each year related to defined contribution plans are recognized under Personnel expenses in the consolidated income statement. The amounts not yet contributed at each year-end are recognized under Provisions – Provision for pensions and similar obligations on the liability side of the consolidated balance sheet. Defined benefit plans The Bank recognizes under Provisions – Provision for pensions and similar obligations on the liability side of the consolidated balance sheet (or under Other assets on the asset side, as appropriate) the present value of its defined benefit post-employment obligations, net of the fair value of the plan assets. The cost of providing retirement benefits is determined using the Projected Unit Credit Method, with actuarial valuations being carried out at the end of each annual reporting period. Plan assets are defined as those that will be directly used to settle obligations and that meet the following conditions: - They are not owned by the Bank, but by a legally separate entity that is not a party related to the Bank. - They are only available to pay or fund post-employment benefits and they cannot be returned to the Bank unless the assets remaining in the plan are sufficient to meet all the benefit obligations of the plan and of the Bank to current and former employees, or they are returned to reimburse employee benefits already paid by the Bank. Post-employment benefits are recognized as follows: - Service cost is recognized in the consolidated income statement and includes the following items: - Current service cost (the increase in the present value of the obligations resulting from employee service in the current period) is recognized under Personnel expenses. - The past service cost, which arises from changes to existing post-employment benefits or from the introduction of new benefits and includes the cost of reductions, is recognized under Provisions (net). - Any gain or loss arising from plan settlements is recognized under Provisions (net). - Net interest on the net defined benefit liability (asset), i.e., the change during the period in the net defined benefit liability (asset) that arises from the passage of time, is recognized under Interest expense and similar charges (Other interest income and similar income if it constitutes income) in the consolidated income statement. - The remeasurement of the net defined benefit obligation is recognized in Accumulated reserves within Shareholders’ equity in the consolidated balance sheet and includes: - Actuarial gains and losses generated in the year, arising from the differences between the previous actuarial assumptions and what has actually occurred and from the effects of changes in actuarial assumptions. - The return on plan assets, excluding amounts included in net interest on the net defined benefit liability (asset). - Any change in the effect of the asset ceiling, excluding amounts included in net interest on the net defined benefit liability (asset). - Remeasurements recognized in other comprehensive income are not reclassified to the consolidated income statement. Further details about post-employment benefits are given in Note 24.c. t) Other long-term employee benefits Other long-term employee benefits, defined as obligations to pre-retirees taken to be those who have ceased to render services at the Bank but who, without being legally retired, continue to have economic rights vis-à-vis the Bank until they acquire the legal status of retiree, are treated for accounting purposes, where applicable, as established above for defined benefit post-employment plans, except that actuarial gains and losses are recognized under Provisions (net) in the consolidated income statement. u) Termination benefits Termination benefits are recognized when there is a detailed formal plan identifying the basic changes to be made, if implementation of the plan has begun, its main features have been publicly announced or objective facts concerning its implementation have been disclosed.
Income tax	v) Income tax Income tax expense represents the sum of the income tax currently payable and deferred income tax. Current income tax The tax currently payable is based on taxable profit for the year. Taxable profit differs from Profit for the year as reported in the consolidated income statement because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The Bank’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the end of the reporting period. Deferred income tax Deferred income tax is the tax expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable profit, tax loss and tax credit carryforwards. Deferred income tax is accounted for using the liability method. Deferred income tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realized based on tax laws and rates that have been enacted or substantively enacted at the reporting date and reflects uncertainty related to income taxes, if there is any. Deferred tax assets are only recognized for temporary differences to the extent that it is considered probable that the Bank will have sufficient future taxable profits against which the deferred tax assets can be utilized, and the deferred tax assets do not arise from the initial recognition (except in a business combination) of other assets and liabilities in a transaction that affects neither taxable profit nor accounting profit. Other deferred tax assets (tax loss and tax credit carryforwards) are only recognized if it is considered probable that, the Bank will have sufficient future taxable profits against which they can be utilized. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Income and expense recognized directly in consolidated total equity are accounted for as temporary differences. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the Bank expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities. Tax assets include the amount of all tax assets, which are broken down into current amounts of tax to be recovered within the next twelve months and deferred amounts of tax to be recovered in future years, including those arising from tax loss or tax credit carryforwards. Tax liabilities include the amount of all tax liabilities (except provisions for taxes), which are broken down into current the amount payable in respect of the income tax on the taxable profit for the year and other taxes in the next twelve months and deferred the amount of income tax payable in future years. Current and deferred income tax for the year The income tax expense is calculated as the sum of the current tax resulting from application of the appropriate tax rate to the taxable profit for the year (net of any deductions allowable for tax purposes), and of the changes in deferred tax assets and liabilities recognized in the consolidated income statement. Current and deferred income tax are recognized in the consolidated income statement, except when they relate to items that are recognized in other comprehensive income or directly in consolidated total equity, in which case, the current and deferred income tax are also recognized in other comprehensive income or directly in consolidated total equity, respectively. Where current tax or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination.
Remaining maturity periods	w) Remaining maturity periods The analysis of the maturities of the balances of certain items in the consolidated balance sheet at 2020 and 2021 year-end is provided in Note 45.
Segment reporting	x) Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the Chief Operating Decision Maker. The Chief Operating Decision Maker (CODM), who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the CEO.
Dividend distribution	y) Dividend distribution Dividend distributions to the Bank’s shareholders are recognized as a liability in the consolidated financial statements in the period in which the dividends are proposed by the Board of Directors and approved by the Bank’s shareholders.
Treasury shares	z) Treasury shares Own equity instruments that are reacquired (treasury shares) are recognized at cost and deducted from consolidated total equity. No gain or loss is recognized in the consolidated income statement on the purchase, sale, issue or cancellation of the Bank’s own equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognized in Accumulated reserves within Shareholders’ equity in the consolidated balance sheet.
Consolidated income statement and other comprehensive income	aa) Consolidated income statement and other comprehensive income This consolidated statement presents the income and expense generated by the Bank as a result of its business activity in the year, and a distinction is made between the income and expenses recognized in the consolidated income statement for the year and the other income and expenses recognized directly in consolidated total equity. Accordingly, this consolidated statement presents: a. Profit for the year. b. The net amount of the income and expenses recognized directly in consolidated total equity that will not be reclassified subsequently to the consolidated income statement. c. The net amount of the income and expenses recognized directly in consolidated total equity that may be reclassified subsequently to the consolidated income statement when certain conditions are met. d. The income tax incurred in respect of the items indicated in b) and c) above, except for the valuation adjustments arising from investments in associated entities accounted for using the equity method, which are presented net. e. Total consolidated comprehensive income, calculated as the sum of a) to d) above, presenting separately the amount attributable to the Parent and the amount relating to non-controlling interests. This consolidated statement presents the items separately by nature, grouping together items that, in accordance with the applicable IFRS, will not be reclassified subsequently to the consolidated income statement since the requirements established by the corresponding IFRS are met.
Consolidated statement of changes in total equity	ab) Consolidated statement of changes in total equity This consolidated statement presents all the changes in consolidated total equity, including the adjustments in the opening balance on Accumulated reserves arising from changes in accounting policies and from the correction of errors. Accordingly, this consolidated statement presents a reconciliation of the carrying amount at the beginning and end of the year of all the consolidated total equity items and the changes are grouped together based on their nature into the following items: a. Adjustments in the opening balance on Accumulated reserves due to changes in accounting policies and from the correction of errors: include those in consolidated total equity arising as a result of the retrospective restatement of the balances in the consolidated financial statements, distinguishing between those resulting from changes in accounting policies and those relating to the correction of errors. b. Income and expense recognized in the year: includes, in aggregate form, the total of the aforementioned items recognized in the consolidated income statement. c. Other changes in consolidated total equity: include the remaining items recognized in consolidated total equity, including, inter alia, increases and decreases in share capital, distribution of profit, transactions involving own equity instruments (treasury shares), transfers between equity items and any other increases or decreases in consolidated total equity.
Consolidated statements of cash flows	ac) Consolidated statement of cash flows The following terms are used in the consolidated statement of cash flows with the meanings specified: ● Cash flows: inflows and outflows of cash and cash equivalents, which are short-term, highly liquid investments that are subject to an insignificant risk of changes in value, irrespective of the portfolio in which they are classified. The Bank classifies as cash and cash equivalents the balances recognized under Cash and balances with the Central Bank in the consolidated balance sheet. ● Operating activities: the principal revenue-producing activities of credit institutions and other activities that are not investing or financing activities. ● Investing activities: the acquisition and disposal of long-term assets and other investments not included in cash and cash equivalents. ● Financing activities: activities that result in changes in the size and composition of the equity and liabilities that are not operating activities.
