Introduction Basis Of Presentation Of Consolidated Financial Statements And Other Information
1. 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 (Brasil) S.A. (Banco Santander or Bank), directly and indirectly controlled by Banco Santander, S.A., headquartered in Spain (Banco Santander Spain), is the lead institution of the Financial and Prudential Conglomerates (Conglomerate Santander) before the Central Bank of Brazil (Bacen), established as a joint-stock corporation, with head office at Avenida Presidente Juscelino Kubitschek, 2041 and 2235 – Building A - Vila Olímpia, in the City of São Paulo, State of São Paulo. Banco Santander operates as a multiple service bank, conducting its operations by means of its commercial, investment, loans, mortgage loans, leasing and foreign exchange portfolios. Through its subsidiaries, also operates in the payment institution, consortium management, securities brokerage, insurance brokerage, consumer finance, digital platforms, benefit management, recovery and non-performing credit management, capitalization and pension markets private, food and food vouchers, food and other administration. The operations are conducted in the context of a group of institutions that operate in an integrated manner in the financial market. The benefits and costs corresponding to the services provided are absorbed between them and are realized in the normal course of business and commuting conditions. The Board of Directors authorized the issuance of the Financial Statements for the year ended on December 31, 2020, at the meeting held on February 25, 2021. These Financial Statements and the accompanying documents were the subject of an unqualified report of the Independent Auditors and a recommendation for approval issued by the Company's Audit Committee and a favorable opinion of the Company's Fiscal Council. b) Basis of presentation of the condensed consolidated financial statements The Consolidated Financial Statements have been prepared in accordance with the standards of the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB), and interpretations issued by the IFRSs Interpretations Committee (current name International Financial Reporting Interpretations Committee - IFRIC). All relevant information specifically related to the financial statements of Banco Santander, and only in relation to these, are being evidenced, and correspond to the information used by Banco Santander in its management. c) Other information c.1) Adoption of new standards and interpretations The following changes to standards were first adopted for the year beginning January 1, 2020: · Material definition: amendments to IAS 1 / CPC 26 “Presentation of the Financial Statements” and IAS 8 / CPC 23 “Accounting Policies, Change in Estimates and Error Correction” · Business definition: changes to IFRS 3 / CPC 15 “Business Combination” · IBOR reform: amendments to IFRS 9 / CPC 48, IAS 39 / CPC 38 and IFRS 7 / CPC 40 - "Financial instruments" · Revised Conceptual Framework for Financial Reporting · IBOR reform: changes to IFRS9, IAS39 and IFRS 7 - In September 2019, the IASB changed its IFRS 9 and IAS 39 standards as well as the related disclosure standard, IFRS 7, on some requirements for hedge accounting. The amendments are due to be implemented on January 1, 2020. The amendments modify some specific requirements on hedge accounting in order to provide assurance on the potential effects of the uncertainty caused by the IBOR reform project. The implementations above did not have a significant impact on these Financial Statements. Rules and interpretations that will come into force after December 31, 2020 As of the date of preparation of these consolidated financial statements, the following rules that have an effective adoption date after January 1, 2021 and have not yet been adopted by the Bank are: · Amendments to IFRS 9, IAS 39 and IFRS 7 "Financial Instruments", IFRS 4 "Insurance Contracts"and IFRS 16 “Leases”: the changes provided for in Phase 2 of the IBOR reform address issues that may affect the financial statements during the reform of a reference interest rate, including the effects of changes in contractual cash flows or hedging relationships resulting from the replacement of a rate with an alternative reference rate (substitution issues). The effective date of application of this amendment is 1st. January 2021. The Group's contracts linked to LIBOR are being reviewed between the parties and will be updated by the respective alternative rates disclosed, plus a spread. Management estimates that the updated cash flows will be economically equivalent to the original, and does not expect material impacts related to this replacement. · Amendment to IAS 16 "Property, plant and equipment": in May 2020, the IASB issued an amendment that prohibits an entity from deducting from the cost of property, plant and equipment the amounts received from the sale of items produced while the asset is being prepared for its intended use. Such revenues and related costs must be recognized in the income for the year. The effective date of application of this amendment is January 1, 2022. · Amendment to IAS 37 "Provision, Contingent Liabilities and Contingent Assets": in May 2020, the IASB issued this amendment to clarify that, for the purpose of assessing whether a contract is onerous, the cost of complying with the contract includes the incremental costs of compliance of this contract and an allocation of other costs that are directly related to the fulfillment of it. The effective date of application of this amendment is January 1, 2022. · IFRS 17 - In May 2017, the IASB issued the IFRS for insurance contracts that aims to replace IFRS 4. IFRS 17 has its implementation date of January 1, 2023. This standard aims to demonstrate greater transparency and useful information in the financial statements, one of the main changes being the recognition of profits as the insurance services are delivered, in order to assess the performance of insurers over time. Banco Santander is evaluating the possible impacts when adopting the standard. · Amendment to IFRS 3 “Business Combination”: issued in May 2020, with the aim of replacing the references from the old version of the conceptual framework to the most recent one. The amendment to IFRS 3 is effective as of January 1, 2022. · Annual improvements - 2018-2020 cycle: in May 2020, the IASB issued the following changes as part of the annual improvement process, applicable from the 1st. January 2022: (i) IFRS 9 - "Financial Instruments" - clarifies which rates should be included in the 10% test for the write-off of financial liabilities. (ii) IFRS 16 - "Leases" - amendment to example 13 in order to exclude the example of lessor payments related to improvements in the leased property. (iii) IFRS 1 "Initial Adoption of International Financial Reporting Standards" - simplifies the application of said standard by a subsidiary that adopts IFRS for the first time after its parent company, in relation to the measurement of the accumulated amount of exchange variations. There are no other IFRS standards or IFRIC interpretations that have not yet come into force that could have a significant impact on the Bank's financial statements. c.2) Estimates used The consolidated results and the calculation of consolidated equity are impacted by the accounting policies, assumptions, estimates and measurement methods used by the Bank's directors in the preparation of interim consolidated financial statements. The Bank makes estimates and assumptions that affect the reported amounts of assets and liabilities of future periods. All estimates and assumptions required, in accordance with IFRSs, are the management's best estimate in accordance with the applicable standard. In the consolidated financial statements, estimates are made by management of the Bank and consolidated entities in order to quantify certain assets, liabilities, revenues and expenses and disclosures of explanatory notes. c.2.1) Critical estimates The critical estimates and assumptions that have the most significant impact on the accounting balances of certain assets, liabilities, revenues and expenses and in the disclosure of explanatory notes, are described below: i. Valuation of the fair value of certain financial instruments Financial instruments are initially recognized at fair value and those that are not measured at fair value through profit or loss are adjusted for transaction costs. Financial assets and liabilities are subsequently measured at the end of each period using valuation techniques. This calculation is based on assumptions, which take into account the management's judgment based on information and market conditions existing at the balance sheet date. Banco Santander classifies the measurements at fair value using the hierarchy of fair value that reflects the model used in the measurement process, segregating the financial instruments between Levels I, II or III. Additional details are in notes 2.e and 46.c8 of the consolidated financial statements of December 31, 2020, which present the sensitivity analysis for Financial Instruments. ii. Provisions for losses on credits for impairment The carrying amount of non-recoverable financial assets is adjusted through the recording of a provision for loss due to “Losses on financial assets (net) - Financial assets measured at amortized cost” in the consolidated income statement. The reversal of previously recorded losses is recognized in the consolidated income statement in the period in which the impairment decreases and can be objectively related to a recovery event. To individually measure the impairment loss on loans assessed for impairment, the Bank considers the conditions of the counterparty, such as its economic and financial situation, level of indebtedness, ability to generate income, cash flow, management, corporate governance and quality of internal controls, payment history, industry experience, contingencies and credit limits, as well as characteristics of assets, such as their nature and purpose, type, sufficiency and guarantees of liquidity level and total credit value , and also based on the historical experience of impairment and other circumstances known at the time of the valuation. To measure the impairment loss on loans assessed collectively for impairment, the Bank separates financial assets into groups taking into account the characteristics and similarities of credit risk, that is, according to the segment, type of assets, guarantees and other factors associated with the historical experience of impairment and other circumstances known at the time of the valuation. iii. IFRS 9 - Financial Instruments: iv. Impairment The Bank recognizes adjustments for expected credit losses with respect to the following financial instruments that are not measured at fair value through profit or loss: - financial assets that are debt instruments; - amounts receivable from leasing; - financial guarantee contracts issued; and - loan commitments issued. No impairment loss is recognized in equity instruments. The Bank measures the adjustments for losses at an amount equal to the expected credit losses during the expected life, except for the instruments below, for which they are recorded as expected credit losses in 12 months: - debt instruments that present a low credit risk at the closing date; and - other financial instruments (except lease receivables) in which the credit risk has not increased substantially since its initial recognition. Adjustments for losses on amounts receivable from leasing are always measured at an amount equal to the expected credit losses during their useful lives. Measurement of expected credit losses The expected credit losses are an estimate weighted by the probability of credit losses. They are measured as follows: - financial assets not subject to impairment at the closing date: as the present value of all cash shortfalls, that is, the difference between the cash flows due to the entity under the contract and the cash flows that the Bank expects to receive; - financial assets subject to impairment at the closing date: as the difference between the gross book value and the present value of estimated future cash flows; - loan commitments: as the present value of the difference between the contractual cash flows due to the Bank if the commitment is used in full and the cash flows that the Bank expects to receive; and - financial guarantee contracts: payments expected to reimburse the holder, less any amounts that the Bank expects to recover. Modified assets If the terms of a financial asset are renegotiated or modified or an existing financial asset is replaced by a new asset due to the debtor's financial difficulties, it is necessary to assess whether the financial asset should be written off and expected credit losses are measured as follows: - If the expected restructuring does not result in a decrease in the existing asset, the expected cash flows from and the modified financial asset are included in the calculation of the cash shortfalls of the existing asset. - If the expected restructuring results in a write-off of the existing asset, the expected fair value of the new asset is treated as the final cash flow of the existing financial asset at the time of its write-off. This amount is included in the calculation of cash shortfalls arising from the existing financial asset discounted from the estimated write-off date until the closing date, using the original effective interest rate of the existing financial asset. Transition: Determination of significant increases in credit risk On each balance sheet calculation date, the Bank assesses whether financial assets recorded at amortized cost and debt financial instruments recorded at fair value through Other Comprehensive Income are subject to impairment, as well as other financial instruments subject to that assessment. A financial asset is “subject to impairment” when one or more events that have a negative impact on the estimated future cash flows of the financial asset have occurred. Evidence that a financial asset is subject to impairment includes the following observable data: - significant financial difficulty for the debtor or issuer; - delays in contractual obligations; - breach of contract, such as default or delay; - the restructuring of a loan or advance by the Bank under conditions that the Bank would not consider interesting to carry out; - the likelihood that the debtor will enter bankruptcy or other financial reorganization; or - the disappearance of an active market for a security due to financial difficulties. A financial instrument that has been renegotiated due to deterioration in the borrower's condition is generally considered to be subject to impairment, unless there is evidence that the risk of not receiving contractual cash flows has been significantly reduced and there is no no other impairment indicator. Presentation of the provision for impairment losses in the balance sheet Provisions for impairment losses are presented in the balance sheet as follows: - financial assets measured at amortized cost: as a deduction from the gross book value of the assets; - loan commitments and financial guarantee contracts: as a provision; and - debt instruments measured at fair value through Other Comprehensive Income: no provision for losses is recognized in the balance sheet, as the book value of these assets corresponds to the fair value. Individual or collective assessment An individual measurement of impairment was based on management's best estimate of the present value of cash flows expected to be received. In estimating these cash flows, management exercised judgment as to the financial situation of a debtor and the net realizable value of any underlying guarantee. Each asset reduced to recoverable value was evaluated in relation to its merits, while the test strategy and the estimated cash flows considered recoverable, were approved by the Bank's credit risk officers. When assessing the need for a collective provision for losses, management considered factors such as credit quality, portfolio size, concentrations and economic factors. In order to estimate the necessary provision, premises were established to define how the inherent losses were modeled and to determine the necessary data parameters, based on historical experience and current economic conditions. Measurement of impairment Losses on impairment of assets measured at amortized cost were calculated as the difference between the carrying amount and the present value of estimated future cash flows, discounted at the asset's original effective interest rate. Impairment losses on assets measured at fair value through Other Comprehensive Income were calculated as the difference between the book value and the fair value. Reversal of impairment For assets measured at amortized cost: If an event that occurred after impairment caused the impairment loss to decrease, the impairment loss was reversed through profit or loss. For debt securities measured at fair value through Other Comprehensive Income: If, in a subsequent period, the fair value of a debt security reduced to recoverable value has increased and this increase could be objectively linked to an event that occurred after recognition from impairment loss, impairment loss was reversed through profit or loss; otherwise, any increase in fair value was recognized through Other Comprehensive Income. Any subsequent recovery in the fair value of an equity instrument measured at fair value through Other Comprehensive Income and reduced to recoverable value was recognized at any time in Other Comprehensive Income. Below is the reconciliation of shareholders' equity resulting from the initial adoption of IFRS 9: Reconciliation of Shareholders' Equity Shareholders' equity before IFRS 9 adjustments - 12/31/2017 87,087,601 Allowance for loan losses (2,149,051) Provisions for contingent commitments (674,513) Remeasurement of assets arising from the new categories 17,806 Others 237,867 Income taxes and deferred social contribution 1,026,066 Shareholders' equity after IFRS 9 adjustments - 01/01/2018 85,545,776 Information, assumptions and techniques used to estimate the impairment Classification of financial instruments by stages The portfolio of financial instruments subject to impairment is divided into three levels, based on the stage of each instrument related to its level of credit risk: - Stage 1: It is understood that a financial instrument at this stage does not have a significant increase in risk since its initial recognition. The provision on this asset represents the expected loss resulting from possible default over the next 12 months; - Stage 2: If a significant increase in risk is identified since initial recognition, without materializing deterioration, the financial instrument will be classified within this stage. In this case, the amount referring to the provision for expected loss due to default reflects the estimated loss of the residual life of the financial instrument. To assess the significant increase in credit risk, quantitative measurement indicators used in normal credit risk management will be used, as well as other qualitative variables, such as the indication of being a non-deteriorating operation if considered as refinanced or included operations in a special agreement; and - Stage 3: A financial instrument is recorded within this stage, when it shows signs of deterioration evident as a result of one or more events that have already occurred and which materialize at a loss. In this case, the amount referring to the provision for losses reflects the expected losses due to credit risk over the expected residual life of the financial instrument. Impairment estimation methodology The measurement of impairment loss is performed using the following factors: - Exposure to Default or EAD: is the value of the transaction exposed to credit risk, including the current balance ratio available that could be provided at the time of default. The models developed incorporate assumptions about changes in the payment schedule for operations. - Probability of Default (PD): is defined as the probability that the counterparty will be able to fulfill its obligations to pay the principal and / or interest. For the purposes of IFRS 9, both will be considered: PD - 12 months (Stage 1), which is the probability that the financial instrument will default in the next 12 months as well as PD - lifetime (Stages 2 and 3), which considers the probability that the counterparty will default between the balance sheet date and the residual maturity date of the operation. The standard requires that future information relevant to the estimation of these parameters must be considered. - Loss on Default (LGD): is the resulting loss in the event of default, that is, the percentage of exposure that cannot be recovered in the event of default. It mainly depends on the guarantees associated with the transaction, which are considered as risk mitigation factors associated with each financial credit asset and the expected future cash flows to be recovered. As established in the regulations, future information must be taken into account for its estimation. - Discount rate: is the rate applied to the estimated future cash flows over the expected life of the asset, to bring them to present value. In order to estimate the aforementioned parameters, the Bank has applied its experience in the development of internal models for the calculation of parameters for both the regulatory environment and internal management purposes. Definition of default The Bank considers that a financial asset is in default when: - it is likely that the debtor will not fully pay its credit obligations to the Bank; or - the debtor presents significant credit obligations to the Bank overdue for more than 90 days, as a general rule. Overdrafts are considered overdue if the customer breaches a recommended limit or has been granted a limit lower than the current open amount. When assessing whether a debtor is in default, the Bank considers indicators: - qualitative - for example, violations of covenants; - quantitative - for example, overdue status and non-payment of another obligation of the same issuer with the Bank; and - based on data collected internally and obtained from external sources. v. Provisions for pension funds Defined benefit plans are recorded based on an actuarial study, carried out annually by a specialized company, at the end of each year, effective for the subsequent period and are recognized in the consolidated income statement in the Interest and similar expenses and Provisions lines (net). The present value of the defined benefit obligation is the present value without deducting any plan assets, from the expected future payments necessary to settle the obligation resulting from the employee's service in current and past periods. Additional details are in note 2.x to the Consolidated Financial Statements of December 31, 2020. vi. Provisions, assets and contingent liabilities Provisions for judicial and administrative proceedings are constituted when the risk of loss of the judicial or administrative action is assessed as probable and the amounts involved are measurable with sufficient security, based on the nature, complexity and history of the actions and the opinion of the legal advisors internal and external. Explanatory note 2.r to the Bank's consolidated financial statements for the year ended December 31, 2020, features information on provisions and contingent assets and liabilities. There were no significant changes in provisions and contingent assets and liabilities of the Bank between December 31, 2019 and December 31, 2020, the date of preparation of these consolidated financial statements. vii. Goodwill The goodwill recorded is subject to the impairment test, at least once a year or in a shorter period, in the event of any indication of impairment of the asset. The basis used for the recoverability test is the value in use and, for this purpose, the cash flow is estimated for a period of 5 years. Cash flow was prepared considering several factors, such as: (i) macroeconomic projections of interest rates, inflation, exchange rate and others; (ii) behavior and growth estimates of the national financial system; (iii) increased costs, returns, synergies and investment plan; (iv) customer behavior; and (v) growth rate and adjustments applied to flows in perpetuity. The adoption of these estimates involves the probability of future events occurring and the alteration of any of these factors could have a different result. The cash flow estimate is based on a valuation prepared by an independent expert annually or whenever there is evidence of a reduction in its recoverable amount, which is reviewed and approved by management. Further details are in note 13. viii. Expectation of realization of tax credits Deferred tax assets and liabilities include temporary differences, identified as the amounts expected to be paid or recovered on differences between the book values ​​of assets and liabilities and their respective calculation bases, and accumulated tax credits and losses and the negative CSLL base. These amounts are measured at the rates expected to be applied in the period in which the asset is realized or the liability is settled. Deferred tax assets are only recognized for temporary differences to the extent that it is considered probable that the consolidated entities will have sufficient future taxable profits against which the deferred tax assets can be used, and the deferred tax assets do not result from the initial recognition (except in a business combination) of other assets and liabilities in an operation that affects neither taxable income nor taxable income. Other deferred tax assets (tax credits and accumulated tax losses) are only recognized if it is considered probable that the consolidated entities will have sufficient future taxable profits to be used. Deferred tax assets and liabilities recognized are revalued on the date of each balance sheet, making appropriate adjustments based on the findings of the analyzes carried out. The expectation of realization of the Bank's deferred tax assets is based on projections of future results and based on a technical study. For further details, see note 2.aa to the Consolidated Financial Statements of December 31, 2020.

The assets and liabilities and foreign subsidiary are converted to Real as follows: - Assets and liabilities are translated at the exchange rate at the balance sheets date. - Revenues and expenses are translated at the monthly average exchange rates. - Gain and losses on translation of net investment are recorded in the statement of comprehensive income, in “exchange rate of investees located abroad”. b) Basis of consolidation i. Subsidiaries “Subsidiaries” are defined as entities over which the Bank has control. Control is based on whether the Bank has: i) power over the investee; ii) exposure, or rights, to variable returns from its involvement with the investee; and iii) the ability to use its power over the investee to affect the amount of the returns, as set forth in the law, the Bylaws or agreement. Consolidation of a subsidiary begins when the Bank obtains control over the subsidiary and ceases when the Bank loses control of the subsidiary. Specifically, income and expense of a subsidiary acquired or disposed during the year are included in the consolidated income statement and other comprehensive income from the date the Bank gains controls until the date when the Bank ceases to control the subsidiary. Profit or loss and each component of Other Comprehensive Income are attributed to the owners of the Bank and to the non-controlling interests even if the effect is attributed to non-controlling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Bank and to the non-controlling interest even if this generates a negative balance for non-controlling interests. All transactions, balances, income and expenses between the companies of the Santander Group are eliminated in the consolidated financial statements. Changes in the Santander Group’s interest in a subsidiary that do not result in loss of control are registered as equity transactions. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to owners of the Company. When the Bank loses control of a subsidiary, the profit or loss on disposal is calculated as the difference between (i) the aggregate 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. Amounts previously recognized in other comprehensive income in relation to the subsidiary are registered (i.e. reclassified to income statement or transferred directly to retained earnings) in the same manner as it would be required if the relevant assets or liabilities are disposed of. The fair value of any investment retained in the former subsidiary at the date when control got lost is considered as the fair value on initial recognition for subsequent accounting under IFRS 9 Financial Instruments: Recognition and Measurement or, when applicable, the costs on initial recognition of an investment in an associate or jointly controlled entity. ii. Interests in joint ventures (jointly controlled entities) and associates Joint ventures mean interests in entities that are not subsidiaries but which are jointly controlled by two or more unrelated entities. This is evidenced by contractual arrangements whereby two or more entities (“ventures”) acquire interests in entities (jointly controlled entities) so that strategic financial and operating decisions affecting the joint venture require the unanimous consent of the ventures. Associates are entities over which the Bank is in a position to exercise significant influence (significant influence is the power to participate in the financial and operating decisions of the investee) but it does not control or has joint control over the investee. In the consolidated financial statements, interest in joint ventures and investments in associates are registered using the equity method, i.e. at the Bank’s share of net assets of the investee, after taking into consideration the dividends received from capital reductions and other related transactions. Relevant information regarding companies registered under the equity method by the Bank is provided in note 11. iii. Business combinations, acquisitions and disposals A business combination means the union of two or more individual business or economic business into one single entity or group of entities and is registered in accordance with IFRS 3 - “Business Combinations”. Business combinations are carried out so that the Bank obtains control over an entity and are recognized for accounting purposes as follow: • The Bank measures the cost of the business combination, defined as the fair value of the assets offered, the liabilities incurred and the equity instruments issued, if any. • The fair values of the assets, liabilities and contingent liabilities of the acquired entity or business, including any intangible assets which might not have been recognized by the acquiree, are estimated at the acquisition date and recognized in the consolidated financial statement. • The excess of the acquisition cost over the fair value of the identifiable net assets acquired are recognized as goodwill (note 13). The excess of fair value of the identifiable net assets over the acquisition cost is an advantageous purchase gain and it is recorded as income on the date of the acquisition. The note 3 includes a description of the most significant transactions carried out in 2020, 2019 and 2018. iv. Investment Funds These include investment funds in which the Santander Group companies hold a substantial interest or the entirety of the interests and are therefore exposed to, or have rights, to variable returns and have the ability to affect those returns through power over the fund, in accordance with IFRS 10 - Consolidated Financial Statements and are therefore, consolidated in these financial statements. c) Definitions and classification of financial instruments i. Definitions “Financial instrument” is any contract that gives rise to a financial asset of one entity and, simultaneously, to a financial liability or financial interest of another entity. “Equity instrument” is any agreement that evidences a residual interest in the asset of the issuing entity after deducting all of its liabilities. “Financial derivative” is a financial instrument whose value changes in response to the change in an observable market variable (such as an interest rate, foreign exchange rate, financial instrument price, market index or credit rating), whose initial investment is zero or very small compared with other financial instruments with a similar response to changes in market factors, and which is settled at a future date. “Hybrid financial instruments” are contracts that simultaneously include a non-derivative host contract together with a derivative, known as an embedded derivative, that is not separately transferable and has the effect to make part of the cash flow of the hybrid contract vary similar to a stand-alone derivative. The following transactions are not treated for accounting purposes as financial instruments: • Investments in subsidiaries, jointly controlled entities and associates (note 3&11). • Rights and obligations under employee benefit plans (note 21). 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, cash balances at Central Banks and other deposits on demand, Changes in the fair value of hedged items in portfolio hedges of interest rate risk (asset side), Hedging derivatives and Investments, which are reported separately. Upon initial recognition of an equity instrument not held for trading, the Bank may irrevocably choose to present subsequent changes in fair value through Other Comprehensive Income. This option is made considering each investment individually and was not used by the Bank. In addition, upon initial recognition, the Bank may irrevocably designate at fair value through profit or loss a financial asset that would otherwise meet the measurement requirements at amortized cost or at fair value through Other Comprehensive Income, if such designation eliminate or substantially reduce an accounting mismatch that could exist. This option was not used by the Bank. Financial assets are included for measurement purposes in one of the following categories: • Financial Assets Measured At Fair Value Through Profit Or Loss Held For Trading: • Financial Assets Measured At Fair Value Through Profit Or Loss: • Non-Trading Financial Assets Mandatorily Measured At Fair Value Through Profit Or Loss: this • Financial Assets Measured At Fair Value Through Profit Or Loss: The results rising from changes in fair value are recognized at the Financial Assets Measured At Fair Value Through Other Comprehensive Income line in the Shareholders´ equity except for cumulative impairment losses which are recognized in statement of profit or loss. When the investment is sold or has evidences of decreases on the fair value due to impairment, the previously recognized result at the same Shareholders´ Equity line, mentioned above is reclassified to the statement of profit or loss. • Financial Assets Measured At Amortized Cost: A financial asset is measured at amortized cost if it meets the following conditions and is not designated at fair value through profit or loss: • The asset is maintained within a business model whose objective is to maintain assets in order to receive contractual cash flows; • The contractual terms of the financial asset generate, on specific dates, cash flows that refer exclusively to payments of the principal and interest on the principal amount outstanding; • A debt instrument is measured at fair value through Other Comprehensive Income if it meets the following conditions and is not designated at fair value through profit or loss; • The asset is maintained within a business model whose objective is achieved by receiving contractual cash flows and by selling financial assets; and • The contractual terms of the financial asset generate, on specific dates, cash flows that refer exclusively to payments of the principal and interest on the principal amount outstanding. Business model assessment The Bank assesses the objective of a business model in which an asset is maintained at the portfolio level, as it better reflects how the business is managed and what information is provided to management. The information considered comprises: - Policies and objectives defined for the portfolio and the application of these policies in practice. Including, if the Administration's strategy is focused on earning contractual interest income, maintaining a specific interest rate profile, aligning the duration of the assets; - How the portfolio's performance is assessed and reported to the Bank's management; - The risks that affect the performance of the business model (and the financial assets held within that business model) and how these risks are managed; - How the business managers are remunerated - for example, if the remuneration is based on the fair value of the managed assets or the contractual cash flows received; - The frequency, volume and timing of sales in previous periods, the reasons for such sales and your expectations about future sales. However, information on sales activity is not considered in isolation, but as part of an overall assessment of the objective defined by the Bank to manage financial assets. Financial assets held for trading or managed, whose performance is assessed based on fair value, are measured at fair value through profit or loss, as (i) they are not held to receive contractual cash flows (ii) nor are they held to receive flows contractual cash flow and sell financial assets. Valuation to determine whether contractual cash flows refer exclusively to principal and interest payments For the purposes of this assessment, “principal” is defined as the fair value of the financial asset upon initial recognition. “Interest” is defined as the consideration for the value of the currency over time and for the credit risk associated with the value of the principal outstanding during a specific period and for other basic risks and costs of loans (for example, liquidity risk and administrative costs), as well as the profit margin. When assessing whether contractual cash flows refer exclusively to payments of principal and interest, the Bank considers the contractual terms of the instrument. This includes assessing whether the financial asset contains a contractual term that could change the term or value of the contractual cash flows in a way that would not meet this condition. When carrying out the assessment, the Bank considers: - contingent events that would change the amount and timing of cash flows; - leverage; - advance payment terms and extension; - terms that limit the Bank's right to cash flows from assets; and - resources that modify the consideration of the currency value over time, for example, periodic adjustment of interest rates. iii. Classification of financial assets for presentation purposes Financial assets are classified by nature into the following headings in the consolidated financial statements: • Cash and balances with the Bacen: cash balances and balances receivable on demand relating to deposits with Bacen and credit institutions. • Financial Assets Measured At Amortized Cost: includes the debit balances of all credit and loans granted by the Bank, other than those represented by securities, as well as finance lease receivables and other debit balances of a financial nature in favor of the Bank, such as checks drawn on credit institutions, balances receivable from clearing houses and settlement agencies for transactions on the stock exchange and organized markets, bonds given in cash, capital calls, fees and commissions receivable for financial guarantees and debit balances arising from transactions not originating in banking transactions and services, such as the collection of rentals and similar items. • Loans and other amounts with credit institutions: credit of any nature in the name of financial institutions. • Loans and advances to clients: includes debit balances of all the remaining credit and loans granted by the Bank, including money market operations through centralized counterparties. • Debt instruments: bonds and other securities that represent a debt for their issuer, that generate an interest return, and that are in the form of certificates or book entries. • 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, joint ventures or associates. Investment fund units are included in this item. • Trading derivatives: includes the fair value in favor of the Bank of derivatives which do not form part of hedge accounting. • Hedging derivatives: includes the fair value in favor of the Bank of derivatives designated as hedging instruments in hedge accounting. • Investments in associates and jointly controlled companies: includes the investments made in the share capital of associates and jointly controlled companies. iv. Classification of financial liabilities for measurement purposes Financial liabilities are classified for measurement purposes into one of the following categories: • Financial Assets At Fair Value Through Profit Or Loss Held for Trading: this category includes 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 ("reverse repos") or borrowed (short positions). • Financial Assets At Fair Value Through Profit Or Loss: financial liabilities are included in this category when they provide more relevant information, either because this eliminates or significantly reduces recognition or measurement inconsistencies (accounting mismatches) that would otherwise arise from measuring assets or 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 Group'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 carried on by financial institutions. v. Classification of financial liabilities for presentation purposes Financial liabilities are classified by nature into the following items in the consolidated financial statements: • Deposits from Bacen: deposits of any nature received from Bacen. • Deposits from credit institutions: deposits of any nature, including credit received and money market operations in the name of credit institutions. • Client deposits: includes deposits of any nature such as demand deposits, saving deposits and time deposits including money market operation received from client. • Marketable debt securities: includes the amount of bonds and other debt represented by marketable securities, other than subordinated liabilities. • Trading derivatives: includes the fair value, with a negative balance for the Bank, of derivatives which do not form part of hedge accounting. • Short positions: includes the amount of financial liabilities arising from the outright sale of financial assets purchased under reverse repurchase agreements or borrowed. • Subordinated liabilities: amount of financing received which, for the purposes of payment priority, ranks behind ordinary debt. This category also includes the financial instruments issued by the Bank which, although equity for legal purposes, do not meet the requirements for classification as equity. • Other financial liabilities: includes the amount of payment obligations having the nature of financial liabilities not included in other items, and liabilities under financial guarantee contracts, unless they have been classified as non-performing. • Hedging derivatives: includes the fair value of the Bank's liability in respect of derivatives, including embedded derivatives separated from hybrid financial instruments, designated as hedging instruments in hedge accounting. • Debt Instruments Eligible to Compose Capital: financial instruments issued by other entities, such as shares, with the nature of equity instruments for the issuer, except investments in subsidiaries, jointly controlled entities or associates. d) Funding, debt notes issued and other liabilities Funding debt rates and other liabilities Instruments are recognized initially at fair value, considered primarily as the transaction price. They are measured at amortized cost and its expenses are recognized as a financial cost. Among the liabilities initial recognition methods, it is important to emphasize those compound financial instruments which are classified as such due to the fact that the instruments contain both, a debt instrument (liability) and an embedded equity component (derivative). The recognition of a compound instrument consists of a combination of (i) a main instrument, which is recognized as an entity’s genuine liability (debt) and (ii) an equity component (derivative convertible into ordinary share). The issue of "Notes" must be registered in specific heading liabilities and updated according to the agreed rates and adjusted by the effect of exchange rate variations, when denominated in foreign currency. All remuneration related to these instruments, such as interest and Exchange variation (difference between the functional currency and the currency in which the instrument was named) shall be recognized as expenses for the period, according to the accrual basis. The relevant details of these issued instruments are described in note 19. e) 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. Financial instruments not measured at fair value through profit or loss, are adjusted by the transaction costs. Financial assets and liabilities are subsequently measured at each period-end as follows: i. Measurement of financial assets Financial assets are measured at fair value, without deduction of estimated costs of transaction that may be incurred on their disposal, except for loans and receivables, held-to-maturity investments, equity instruments whose fair value cannot be determined in a sufficiently objective manner and financial derivatives that have as equity instruments subject and are settled by delivery of those instruments. 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, transparent and deep 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 valuation techniques commonly used by market participants, according to the specific features of the instrument to be measured and, particularly, the various types of risk associated with it. All derivatives are recognized in the balance sheets at fair value from the trade date. If the fair value is positive, they are recognized as assets and if the fair value is negative, they are recognized as liabilities. The changes in the fair value of derivatives from the trade date are recognized in “Gains (losses) on financial assets and liabilities” in the consolidated income statement. Specifically, the fair value of standard financial derivatives included in the portfolios of financial assets or liabilities held for trading is deemed to be their daily quoted price and 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” derivatives. The fair value of OTC derivatives is taken to be the sum of the future cash flows arising from the instrument, discounted to present value at the date of measurement (“present value” or “theoretical close”) using valuation techniques commonly used by market participants: “net present value” (NPV), option pricing models and other methods. “Financial Assets Measured At Amortized Cost” and “Held-to-maturity investments” are measured at amortized cost using the effective interest method. “Amortized cost” is the acquisition cost of a financial asset or liability plus or minus, as appropriate, the principal repayments and the cumulative amortization (taken to the income statement) between the difference of the initial cost and the maturity amount. In the case of financial assets, amortized cost furthermore includes any reductions for impairment or uncollectibility. In the case of loans and receivables hedged in fair value hedges, the changes in the fair value of these assets related to the risk or risks being hedged are recognized. The “effective interest rate” is the discount rate that exactly matches the initial amount of a financial instrument to all its estimated cash flows of all kinds over its remaining life. For fixed rate financial instruments, the effective interest rate coincides with the contractual interest rate established on the acquisition date plus, where applicable, the fees and transaction costs that, because of their nature, form part of their financial return. In the case of floating rate financial instruments, the effective interest rate coincides with the rate of return prevailing in all connections until the next benchmark interest reset date. Equity instruments whose fair value cannot be determined in a sufficiently objective manner are measured at acquisition cost adjusted, where appropriate, by any related impairment loss. Equity instruments whose fair value cannot be calculated in a sufficiently objective manner are measured at acquisition cost, adjusted, as the case may be, to the related impairment losses. The amounts at which the financial assets are recognized represent, in all material respects, the Bank’s maximum exposure to credit risk at each reporting date. Also, the Bank has received collateral and other credit enhancements to mitigate its exposure to credit risk, which consist mainly of mortgage guarantees, cash collateral, equity instruments and personal security, assets leased out under leasing and renting agreements, assets acquired under repurchase agreements and securities loans and derivatives. ii. Measurement of financial liabilities In general, financial liabilities are measured at amortized cost, as defined above, except for those included under “Financial Assets Measured At Fair Value Through Profit Or Loss” and financial liabilities designated as hedge items (or hedging instruments) in fair value hedges, which are measured at fair value. iii. Recognition of fair value changes As a general rule, changes in the carrying amount of financial assets and liabilities are recognized in the consolidated income statement, distinguishing between those arising from the accrual of interest and similar items -which are recognized under “Interest and similar income” or “Interest expense and similar charges”, as appropriate - and those arising for other reasons, which are recognized at their net amount in the heading “Gains (losses) on financial assets and liabilities (net)”. Adjustments due to changes in fair value arising from Available-for-sale financial assets are recognized temporarily in equity in then heading “Other Comprehensive Income”. Items charged or credited to this account remain in the Bank’s consolidated equity until the related assets are written-off, whereupon they are charged to the consolidated income statement. iv. Hedging transactions The consolidated entities use financial derivatives for the following purposes: i) to provide these instruments to clients who request them in the management of their market and credit risks; ii) to use these derivatives in the management of the risks of the Bank entities' own positions and assets and liabilities (“hedging derivatives”); and iii) to obtain gains from changes in the prices of these derivatives (“financial derivatives”). Financial derivatives that do not qualify for hedge accounting are treated for accounting purposes as trading derivatives. A derivative qualifies for hedge accounting if all the following conditions are met: 1. The derivative hedges one of the following three types of exposure: a. Changes in the fair value of assets and liabilities due to fluctuations, among other, in the interest rate and/or exchange rate to which the position or balance to be hedged is subject (“fair value hedge”); b. Changes in the estimated cash flows arising from financial assets and liabilities, commitments and highly probable forecast transactions (“cash flow hedge”); c. The net investment in a foreign operation (hedge of a net investment in a foreign operation). 2. It is effective in offsetting exposure inherent in the hedged item or position throughout the expected term of the hedge, which means that: a. At the date of arrangement the hedge is expected, under normal conditions, to be highly effective (prospective effectiveness). b. There is sufficient evidence that the hedge was actually effective during the whole life of the hedged item or position (retrospective effectiveness). 3. There must be adequate documentation evidencing the specific designation of the financial derivative to hedge certain balances or transactions and how this effective hedge was expected to be achieved and measured, provided that this is consistent with the Bank’s management of own risks. The changes in value of financial instruments qualifying for hedge accounting are recognized as follows: a. In fair value hedges, the gains or losses arising on both the hedging instruments and the hedged items (attributable to the type of risk being hedged) are recognized directly in the consolidated income statement. b. In cash flow hedges, the effective portion of the change in value of the hedging instrument is recognized temporarily in equity under “Other comprehensive Income - Cash flow hedges” until the forecast transactions occur, when it is recognized in the consolidated income statement, unless, if the forecast transactions result in the recognition of non-financial assets or liabilities, it is included in the cost of the non-financial asset or liability. The ineffective portion of the change in value of hedging derivatives is recognized directly in the consolidated income statement. c. The ineffective portion of the gains and losses on the hedging instruments of cash flow hedges and hedges of a net investment in a foreign operation are recognized directly under “Gains (losses) on financial assets and liabilities (net)” in the consolidated income statement. If a derivative designated as a hedge instrument no longer meets the requirements described above due to expiration, ineffectiveness or for any other reason, the derivative is classified as a derivative measured at fair value through profit or loss. When fair value hedge accounting is discontinued (expired, sold our no longer meet hedge accounting criteria) the adjustments previously recognized on the hedged item are transferred to profit or loss at the effective interest rate re-calculated at the date of hedge discontinuation. The adjustments must be fully amortized at maturity. When cash flow hedges are discontinued, any cumulative gain or loss on the hedging instrument recognized in equity in the heading "Other comprehensive Income” (from the period when the hedge was effective) remains recognized in equity until the forecast transaction occurs at which time it is recognized in profit or loss, unless the transaction is no longer expected to occur, in which case any cumulative gain or loss is recognized immediately in profit or loss. For the accounting and disclosure of the hedge accounting structures as of December 31, 2019, the bank used the faculty of IFRS 9, to maintain the practices determined by IAS 39. f) Settlement of financial assets and liabilities Derecognition of Financial Assets The Bank derecognizes a financial asset when the contractual rights to the cash flows of the asset expire or when it transfers the rights to the receipt of the contractual cash flows in a transaction in which essentially all the risks and benefits of ownership of the financial asset are transferred or in which the Bank does not transfer or retain substantially all the risks and rewards of ownership of the financial asset and does not control the financial asset. The difference between the carrying amount of the asset (or book value allocated to the portion of the asset disposed) and the sum (i) of the consideration received (including any new assets obtained, less any new liabilities assumed) and (ii) any accumulated gains or losses recognized in "Other Comprehensive Income" is recorded in the income statement. As from the date of the adoption of IFRS, mentioned above, any accumulated gains / losses recognized in "Other Comprehensive Income" in relation to equity instruments designated at fair value through Other Comprehensive Income are not recorded in the statement of income through the write-off of these securities. The Bank carries out transactions in which it transfers the assets recognized in its balance sheet, but maintains

(1) Banco Santander was a creditor for certain overdue credit operations that had real estate as collateral. The operation for the recovery of these credits consists of the contribution of real estate as collateral to the capital of the Real Estate Investment Fund and the consequent transfer of the Fund's quotas to Banco Santander, by means of a donation in payment of the aforementioned credit operations. (2) Banco Santander, through its subsidiaries, holds the risks and benefits of Santander Paraty and the Santander FI Hedge Strategies Sub-Fund, residing in Ireland, and both are fully consolidated in their Consolidated Financial Statements. In the Irish market, an investment fund cannot act directly and, for this reason, it was necessary to create another structure (a sub-fund), Santander FI Hedge Strategies. Santander Paraty does not have an equity position, and all records come from the financial position of Santander FI Hedge Strategies. (3) Refers to a structure where Banco Santander sold certain credit operations, which had already been transferred to losses (operations overdue for more than 360 days) to this fund. Atual Serviços de Recuperação de Creditos e Meios Digitais S.A. (current corporate name of Atual Companhia Securitizadora de Creditos Financeiros), a company controlled by Banco Santander, holds 100% of the shares of this fund. (4) Indirectly controlled by Atual Serviços de Recuperação de Creditos e Meios Digitais S.A. (5) Fund controlled through Banco Bandepe S.A. (6) This fund started to be consolidated in June 2019 and is controlled through Atual Serviços de Recuperação de Creditos e Meios Digitais S.A. (7) This fund started to be consolidated in August 2020 and is controlled through Atual Serviços de Recuperação de Creditos e Meios Digitais S.A. Corporate movements were implemented in order to reorganize the entities' operations and activities in accordance with the Santander Conglomerate's business plan. a) Disposal of equity interest held in Super Pagamentos e Administração de Meios Eletrônicos S.A. On February 28, 2020, the sale to Superdigital Holding Company, SL, a company indirectly controlled by Banco Santander, SA, of the shares representing the entire share capital of Super Pagamentos e Administração de Meios Eletrônico SA (“Superdigital”) for the amount of R$270,000.

Derivative Financial Instruments And Short Positions
8. Derivative financial instruments and Short positions	8. Derivative financial instruments and Short positions The main risk factors associated to derivatives contracted are related to exchange rates, interest rates and stocks. To manage these and other market risk factors the Bank uses practices which include the measurement and follow up of the limit´s usage previously defined on internal committees, as well as the daily follow up of the portfolios values in risk, sensitivities and changes in the interest rate and exchange exposure, liquidity gaps, among other practices which allow the control and follow up on the main risk metrics that can affect the Bank´s position in the several markets which it acts. Based on this management model the Bank has accomplished its goal, using operations with derivatives, in optimize the relation risk/benefits even in situation with great volatility. The derivatives fair value is determined through quotation of market prices. The swaps contracts fair value is determined using discounted cash flow modeling techniques, reflecting suitable risk factors. The fair value of NDF and Future contracts are also determined based on the quotation of market prices for derivatives traded in specific chamber (i.e. stock Exchange for example) or using the same methodology applied for swap contracts. The fair value of options derivatives (call and put) is determined based on the mathematical models, such as Black & Scholes, using yield rates, implied volatilities and the fair value of the corresponding asset. The current market prices are used to price the volatilities. For the derivatives which do not have prices directly disclosed by specific chamber, their fair values are obtained through pricing models which use market information, based on disclosed prices of more liquid assets. Interest rate curves and market volatilities are extracted from theses prices to be used as first input in these models. a) Trading and hedging derivatives a.1) Derivatives Portfolio Summary of Trading and Hedging Derivatives 2020 2019 2018 Assets Swap Differentials Receivable 14,729,642 14,634,863 14,640,289 Option Premiums to Exercise 4,974,618 1,065,753 716,936 Forward Contracts and Others 9,166,361 4,745,101 3,006,221 Total 28,870,621 20,445,717 18,363,446 Liabilities Swap Differentials Payable 18,327,611 16,458,397 15,952,283 Option Premiums Launched 4,926,994 1,699,729 563,787 Forward Contracts and Others 8,725,333 4,271,852 1,950,765 Total 31,979,938 22,429,978 18,466,835 Summary by Category 2020 2019 2018 Notional Fair Value Notional (1) Fair Value Notional (1) Fair Value Swap 398,925,842 (3,597,969) (1,823,534) (1,431,110) Assets 278,752,387 14,729,642 282,164,189 147,010,930 177,233,869 44,487,274 CDI (Interbank Deposit Rates) 41,316,315 3,010,880 40,550,627 16,908,791 36,135,015 24,267,591 Fixed Interest Rate - Real 54,159,848 9,607,342 47,140,927 - 47,968,999 - Indexed to Price and Interest Rates 5,124,411 - 2,388,118 - 2,581,215 - Foreign Currency 178,076,136 1,039,529 192,084,517 130,102,139 90,495,240 20,219,683 Others 75,676 1,071,891 - - 53,400 - Liabilities 120,173,455 (18,327,611) 279,803,610 (148,834,464) 176,385,349 (45,918,384) CDI (Interbank Deposit Rates) 33,239,801 (13,693,733) 24,353,405 - 11,801,600 - Fixed Interest Rate - Real 45,088,689 (2,772,479) 67,937,624 (24,079,732) 88,317,044 (23,075,374) Indexed to Price and Interest Rates 33,026,692 (450,958) 125,829,755 (123,445,067) 24,308,601 (21,775,017) Foreign Currency 6,636,885 153,695 60,394,529 - 50,748,008 - Others 2,181,388 (1,564,135) 1,288,297 (1,309,665) 1,210,096 (1,067,993) Options 2,043,286,085 47,624 1,446,536,133 (1,222,465) 335,073,080 153,149 Purchased Position 1,006,266,897 4,974,618 678,089,904 381,706 149,076,796 716,936 Call Option - US Dollar 1,188,387 39,202 171,871 (281) 14,518,058 239,079 Put Option - US Dollar 1,948,673 109,075 1,456,975 4,355 8,893,620 90,736 Call Option - Other 134,761,947 1,093,583 98,154,363 818,664 3,118,344 131,297 Interbank Market 101,421,659 556,039 98,154,363 819,262 639,488 4,537 Others (2) 33,340,288 537,544 - (598) 2,478,856 126,760 Put Option - Other 868,367,889 3,732,758 578,306,695 (441,032) 122,546,774 255,824 Interbank Market 864,852,555 3,729,297 578,306,695 (440,959) 121,782,816 217,726 Others (2) 3,515,334 3,461 - (73) 763,958 38,098 Sold Position 1,037,019,188 (4,926,994) 768,446,229 (1,604,171) 185,996,284 (563,787) Call Option - US Dollar 1,537,670 699,243 254,945 (1,472) 7,615,856 (101,034) Put Option - US Dollar 2,315,919 (192,335) 263,994 (2,842) 12,160,912 (169,431) Call Option - Other 130,919,394 (453,919) 174,166,802 (440,731) 31,679,919 (66,002) Interbank Market 120,156,285 (464,405) 174,166,802 (440,959) 29,609,298 (13,195) Others (2) 10,763,109 10,486 - 228 2,070,621 (52,807) Put Option - Other 902,246,206 (4,979,984) 593,760,488 (1,159,126) 134,539,597 (227,320) Interbank Market 869,328,317 (4,597,427) 593,760,488 (1,159,038) 133,703,672 (179,841) Others (2) 32,917,888 (382,557) - (88) 835,925 (47,479) Futures Contracts 270,258,566 - 433,873,180 - 289,508,200 - Purchased Position 110,275,866 - 72,912,029 - 86,203,734 - Exchange Coupon (DDI) 12,438,695 - 7,394,951 - 20,590,068 - Interest Rates (DI1 and DIA) 97,837,171 - 55,430,519 - 32,690,685 - Foreign Currency - - 9,978,419 - 32,456,813 - Indexes (3) - - - - 466,168 - Others - - 108,140 - - - Sold Position 159,982,699 - 360,961,151 - 203,304,466 - Exchange Coupon (DDI) 73,114,014 - 146,032,485 - 146,948,795 - Interest Rates (DI1 and DIA) 67,958,767 - 196,170,105 - 54,160,203 - Foreign Currency 18,653,658 - 17,305,604 - 1,992,574 - Indexes (3) 256,261 - 290,254 - 202,894 - Treasury Bonds/Notes - - 1,162,703 - - - Forward Contracts and Others 163,040,700 441,028 169,401,317 473,249 90,910,841 1,055,456 Purchased Commitment 96,309,648 9,166,361 79,970,842 426,991 38,666,269 1,303,561 Currencies 87,254,202 5,026,567 79,969,759 426,986 38,095,625 1,250,706 Others 9,055,447 4,139,794 1,083 5 570,644 52,855 Sold Commitment 66,731,052 (8,725,333) 89,430,475 46,258 52,244,572 (248,105) Currencies 64,986,757 (4,846,929) 89,426,698 46,170 51,958,529 (252,160) Others 1,744,295 (3,878,404) 3,777 88 286,043 4,055 (1) Nominal value of updated contracts.

Total Return Swaps Credit derivatives are where the exchange of the return of the reference obligation occurs through a cash flow and where, in the event of a credit event, the protection buyer is usually entitled to receive from the protection seller the equivalent of the difference between the and the fair value (market value) of the reference obligation on the settlement date of the contract. Credit Default Swaps These are credit derivatives where, in the event of a credit event, the protection buyer is entitled to receive from the protection seller the equivalent of the difference between the face value of the CDS agreement and the fair value (market value) of the reference obligation on the settlement date of the contract. In return, the seller receives compensation for the sale of the protection.

The derivatives used as hedging instruments are represented as follows: a.6.i) Fair Value Hedge Banco Santander’s fair value hedging strategy consists of hedging the exposure to changes in fair value related to recognized assets and liabilities. The fair value strategy adopted by management segregates transactions by risk factor (e.g. Real/Dollar foreign exchange risk, fixed Reais interest rate risk, Dollar foreign exchange coupon risk, inflation risk, interest rate risk, etc.). The transactions generate exposures that are consolidated by risk factor and compared with internal pre-established limits. In order to hedge the changes of fair value in receivables and interest payments, Santander uses interest rate Swap contracts related to pre-fixed (pre define interest rate at inception) assets and liabilities. Banco Santander applies fair value hedge as follows: • Designates Foreign Currency + Coupon versus %CDI and Pre - Real Interest Rate or contracts dollar futures (DOL, DDI/DI) as derivatives instruments in Hedge Accounting structures, with foreign currency loan operations being the object of such transactions. • The Bank has a portfolio of credit assets denominated in US dollars at the fixed rate in the balance sheet of Santander EFC, whose operations are recorded in Euro. As a way of managing this mismatch, the Bank designates each Euro Floating Foreign Currency swap versus Fixed Dollar as the market risk hedge of the corresponding loan. • The Bank has a pre-fixed interest rate risk generated by government securities (NTN-F and LTN) in the Financial Assets portfolio measured through Other Comprehensive Income. To manage this mismatch, the entity contracts DI futures on the Stock Exchange and designates them as a derivative instrument in a hedge accounting framework. • The Bank has a risk to the IPCA (Broad pricing to consumers index) generated by debentures in the portfolio of securities available for sale. To manage this mismatch, it contracts IPCA (DAP) futures on the Stock Exchange and designates them as a derivative instrument in a Hedge Accounting structure. In order to assess the effectiveness and measure the ineffectiveness of the strategies, the institution complies with international accounting standard IAS 39, which requires that the effectiveness test be performed at the beginning (prospective test) of the hedge structure and be repeated periodically (prospective and retrospective tests) in order to demonstrate that the hedge ratio remains effective. To assess the effectiveness and measure the ineffectiveness of the strategies, the Bank follows IAS 39, which requires that the effectiveness test be performed at the beginning (prospective test) of the hedge structure, and repeated periodically (prospective and retrospective test) to demonstrate that the hedge relationship remains effective. a) Prospective test: a.1) The initial prospective test (at inception): a.2) The prospective periodic test: b) Retrospective test: In fair value hedges, gains or losses, both on hedge instruments and on hedged items (attributable to the type of risk being protected) are recognized directly in the consolidated income statement. 2020 2019 2018 Hedge Structure Effective Portion Accumulated Portion Ineffective Effective Portion Accumulated Portion Ineffective Effective Portion Accumulated Portion Ineffective Fair Value Hedge Brazilian Treasury Bonds (LTN, NTN-F) (2,183,841) - (2,853,807) - (1,381,156) - Bonds (LEA) - - (61,761) - (191,472) - Resolution 2770 - - (94) - 689 - Trade Finance Off (5,092) - (4,015) - (58,020) - Total (2,188,933) - (2,919,677) - (1,629,959) - 12/31/2020 Hedge Hedge Instruments Objects Curve Adjustment to Accounting Curve Adjustment to Accounting Strategies Value Market Value Value Value Market Value Value Future Contracts 46,649,331 - 46,649,331 42,529,036 2,802,690 45,331,727 Hedge of Securities 46,649,331 - 46,649,331 42,529,036 2,802,690 45,331,727 12/31/2019 Hedge Hedge Instruments Objects Curve Adjustment to Accounting Curve Adjustment to Accounting Strategies Value Market Value Value Value Market Value Value Swap Contracts 3,249,742 101,264 3,351,004 3,555,326 662,773 4,218,099 Credit Operations Hedge 1,118,210 28,993 1,147,202 1,423,809 63,231 1,487,040 Hedge of Securities 2,131,532 72,271 2,203,802 2,131,517 599,542 2,731,059 Future Contracts 789,631 - 789,631 45,427,125 3,000,490 48,427,614 Hedge of Securities 789,631 - 789,631 45,427,125 3,000,490 48,427,614 12/31/2018 Hedge Hedge Instruments Objects Curve Adjustment to Accounting Curve Adjustment to Accounting Strategies Value Market Value Value Value Market Value Value Swap Contracts 3,908,082 140,447 4,048,529 3,921,249 65,014 3,986,263 Credit Operations Hedge 1,152,249 115,180 1,267,429 1,166,387 50,668 1,217,055 Hedge of Securities 2,755,833 25,267 2,781,100 2,754,862 14,346 2,769,208 Future Contracts 41,286,091 - 41,286,091 44,130,671 (205,941) 43,924,730 Hedge of Securities 41,286,091 - 41,286,091 44,130,671 (205,941) 43,924,730 (*) The Bank has market risk hedge strategies, the objects of which are assets in its portfolio, which is why we demonstrate the passive edge of the respective instruments. For structures whose instruments are futures, we show the balance of the calculated daily adjustment, recorded in a clearing account. a.6.II) Cash Flow Hedge The Bank's cash flow hedge strategies consist of hedging exposure to changes in cash flows, interest payments and exchange rate exposure, which are attributable to changes in interest rates on recognized assets and liabilities and changes exchange rates for unrecognized assets and liabilities. The Bank applies the cash flow hedge as follows: • Enters into fixed-rate asset swaps and foreign currency liabilities and designates them as a hedging instrument in a Cash Flow Hedge structure, with the object of foreign currency loan operations negotiated with third parties through offshore agencies and securities Brazilian foreign debt held to maturity. • It contracts Dollar futures or DDI + DI futures (Synthetic Dollar Futures) and designates them as a protection instrument in a Cash Flow Hedge structure, having as object item the Bank's credit portfolio in Dollars and Promissory Notes in securities portfolio available for sale. • The Bank has a portfolio of assets indexed to the Euro and traded at offshore branches. In the transaction, the value of the asset in Euro will be converted to the Dollar by the rate of the exchange contract of the transaction. As from the conversion, the principal amount of the funding, already expressed in US dollars, will be adjusted by a floating or fixed rate. The assets will be covered with Swap Cross Currency in order to cross the risk in Euro for LIBOR + Coupon. To assess the effectiveness and measure the ineffectiveness of these strategies, Banco Santander follows IAS 39, which indicates that the effectiveness test must be carried out in the design/start of the hedge structure (prospective test) and repeated periodically (prospective and retrospective test) for demonstrate that the expectation of the hedge relationship remains effective (between 80 and 125%). In this hedge strategy, the effectiveness tests (prospective/retrospective) are conducted by comparing two proxies, one for the hedged object and the other for the instrument. The hedge object proxy is a “conceptual” swap, where the passive “tip” simulates the part of the Stable Portion to be protected and the active pre-fixed “tip” is identical to the set of futures designated as a hedge, being consistent with market rates practiced on the day the hedge is designated. The hedge instrument proxy is a “conceptual” swap, where the active “tip” is made up of the number of futures contracts designated as hedging, and the passive pre-fixed “tip” is the rate negotiated in the acquisition of these contracts. The proxy is stable throughout the strategy since the contracts are maintained until maturity. Any ineffectiveness is recognized in the income statement. a) Prospective Test: a.1) Periodic Prospective Test: a.2) Initial Prospective Test: b) Retrospective test: it must be performed monthly with historical data to demonstrate cumulatively that the hedge was effective, according to the methodology presented above. Any ineffectiveness is recognized in the income statement. The Ineffective portion is measured using the prospective hedge test and if identified recognized in the income statement in the line Gains (losses) on financial assets and liabilities (net). Effectiveness should be between 80% and 125%. In cash flow hedges, the effective portion of the variation in the value of the hedge instrument is temporarily recognized in equity under the caption “Other comprehensive income - cash flow hedges” (Note 26) until the anticipated transactions occur, when this portion is recognized in the consolidated income statement, except if the anticipated transactions result in the recognition of non-financial assets or liabilities, this portion will be included in the cost of the financial asset or liability. The non-effective portion of the variation in the value of foreign exchange hedge derivatives is recognized directly in the consolidated income statement. And the ineffective portion of the gains and losses on cash flow hedge instruments in an operation abroad is recognized directly in “Gains (losses) on financial assets and liabilities (net)” in the consolidated statements of income. 2020 2019 2018 Hedge Structure Effective Portion Accumulated Portion Ineffective Effective Portion Accumulated Portion Ineffective Effective Portion Accumulated Portion Ineffective Cash Flow Hedge Eurobonds 14,666 - (6,074) - (8,925) - Trade Finance Off 58,088 - 139,852 - (16,453) (3,981) Government Securities (LFT) 727,437 - 503,665 - 331,922 - Bank Deposit Certificate - CDB - - - - 1,225 - Total 800,190 - 637,443 - 307,769 (3,981) 12/31/2020 Hedge Instruments Hedge Object Accounting Adjustment to Market Accounting Strategies Value - liability Market Value Value Value Swap Contracts 1,428,053 1,428,053 1,302,666 1,302,666 Hedge of Securities 1,428,053 1,428,053 1,302,666 1,302,666 Future Contracts 19,500,234 19,500,234 23,447,934 23,447,934 Hedge of Securities 19,500,234 19,500,234 23,447,934 23,447,934 12/31/2019 Hedge Instruments Hedge Object Accounting Adjustment to Market Accounting Strategies Value - liability Market Value Value Value Swap Contracts 1,361,658 35,110 1,396,768 1,324,685 Credit Operations Hedge 435,872 (3,494) 432,378 399,831 Hedge of Securities 925,786 38,604 964,390 924,854 Future Contracts 54,460,972 - 54,460,972 7,726,566 Credit Operations Hedge (1) 50,975,253 - 50,975,253 4,506,878 Hedge of Securities 3,485,719 - 3,485,719 3,219,688 12/31/2018 Hedge Instruments Hedge Object Accounting Adjustment to Market Accounting Strategies Value - liability Market Value Value Value Swap Contracts 2,227,004 (24,206) 2,202,798 2,423,678 Credit Operations Hedge 1,032,283 68,730 1,101,012 1,198,921 Hedge of Securities 1,194,721 (92,936) 1,101,786 1,224,757 Future Contracts 44,541,939 - 44,541,939 17,224,115 Credit Operations Hedge (1) 44,000,952 - 44,000,952 16,910,915 Hedge of Securities 540,987 - 540,987 313,200 (*) The Bank has cash flow hedge strategies, the objects of which are assets in its portfolio, which is why we have shown the liability side of the respective instruments.

Intangible Assets - Goodwill
13. Intangible assets - Goodwill	13. Intangible assets - Goodwill Goodwill is the difference between the acquisition cost and the Bank's participation in the net fair value of assets, liabilities and contingent liabilities of the acquired company. When the difference is negative (negative goodwill), it is recognized immediately through income statement. In accordance with IAS 36 the goodwill is tested annually for impairment or whenever there is an evidence of reduction on the recoverable value of the cash generating unit to which the goodwill was allocated. Goodwill is recognized at cost considering the accumulated impairment losses. Impairment losses related to goodwill are not reversible. Gains and losses related to the sale of an entity include the carrying amount of goodwill relating to the entity sold. The goodwill recorded is subject to impairment test (note 2.o.i) and has been allocated according to the operating segments (note 44). Based on the assumptions described bellow, no impairment loss was recognized for goodwill at December 31, 2020, 2019 and 2018 Thousand of reais 2020 2019 2018 Breakdown Banco ABN Amro Real S.A.

At the end of each year, a qualitative assessment is carried out in order to check the existence of signs of impairment. For the years 2020, 2019 and 2018, no indication of impairment was identified. During the year ended December 31, 2020, and the prior years there was no evidence of impairment. In the goodwill impairment test, discount rates and perpetuity growth are the most sensitive assumptions for calculating the present value (value in use) of discounted future cash flows. With a variation of + 0.25% or -0.25% in these rates, the value of future cash flows discounted to present value continues to indicate the absence of impairment.

For accounting purposes, although the interest should be reflected in the income statement for tax deduction, the charge is reversed before the calculation of the net income in the financial statements and deducted from the shareholders’ equity since it is considered as dividend. (2) PIS and COFINS are considered a profit-base component (net basis of certain revenues and expenses), therefore and accordingly to IAS 12 they are recorded as income taxes.

Administration in this case the possibility of loss on impairment or disposal is remote and only applies to the entity as a whole and according to the characteristics of the business combination performed, it is not possible to segregate and identify the business originally acquired.

Exchange Hedge of Grand Cayman, branch in Luxembourg and of Santander Brasil EFC Banco Santander operates an agency in the Cayman Islands, a branch in Luxembourg, and a subsidiary called Santander Brasil Establecimiento Financiero de Credito, EFC, or "Santander Brasil EFC" (an independent subsidiary in Spain), which are used primarily to raise funds in the capital and financial markets to provide the Bank with credit lines that are extended to its clients for foreign trade and working capital financing. To hedge the exposure to exchange rate variations, the Bank uses derivatives and funding (economic hedge). In accordance with Brazilian tax rules, gains or losses arising from the impact of the appreciation or depreciation of the Real on foreign investments are not taxable or deductible for PIS / COFINS / IR / CSLL purposes, while the gains or losses of the derivatives used as hedges are taxable or deductible.

Fair Value Of Financial Assets And Liabilities
29. Fair value of financial assets and liabilities	29. Fair value of financial assets and liabilities Under IFRS 13, the fair value measurement uses a fair value hierarchy that reflects the model used in the measurement process which should be in accordance with the following hierarchical levels: Level 1: Level 2: Level 3: Trading Financial Assets, Other financial assets at fair value on through income statement, Available-for-sale financial assets and Financial liabilities held for trading. Level 1: Level 2: Level 3: Derivatives Level 1: Level 2: When pricing the financial instruments aforementioned, it is used the Black-Scholes Model (exchange rate options, interest rate options; caps and floors) and the present value method (discount of future values by market curves).

Definitions were included related to instruments, risk factors and deadlines as well as observability degree of market prices and its importance in the fair value measurement model. The application of such definitions since September 2018 resulted in reclassifications of certain financial instruments, as shown in the section “Changes of Fair Value Level 3”.

115,212 710,219 (183,973) - 641,458 Fair value movements linked to credit risk Changes in fair value attributable to changes in credit risk are determined on the basis of changes in the prices of credit default swaps compared to similar obligations of the same obligor when such prices are observable, since these credit swaps better reflect the market risk assessment for a specific financial asset. When such prices are not observable, changes in fair value attributable to changes in credit risk are determined as the total value of changes in fair value not attributable to changes in the underlying interest rate or other observed market rates. In the absence of specific observable data, this approach provides a reasonable approximation of changes attributable to credit risk, as it estimates the margin change above the reference value that the market may require for the financial asset. In 2018, there were no significant changes between the fair value categories due to changes in credit risk. Financial assets and liabilities not measured at fair value The financial assets owned by the Bank are measured at fair value in the accompanying consolidated balance sheets, except for loans and receivables. Similarly, the Bank’s financial liabilities except for financial liabilities held for trading and those measured at fair value - are measured at amortized cost in the consolidated balance sheets. i) Financial assets measured at other than fair value Below is a comparison of the carrying amounts of financial assets of the Bank measured by a value other than the fair value and their respective fair values on December 31, 2020, 2019 and 2018: During 2020, The Bank reclassified R$ 53,357,038 of “loans and amounts due from credit institutions” from level 2 to level 3, as there was no active trading market for these instruments.” 12/31/2020 Assets Accounting Value Fair Value Level 1 Level 2 Level 3 Cash and Balances With The Brazilian Central Bank 20,148,725 20,148,725 20,148,725 - - Financial Assets Measured At Amortized Cost Loans and amounts due from credit institutions 112,849,776 112,849,776 - 59,492,738 53,357,038 Loans and advances to customers 393,707,229 396,878,319 - 4,530,041 392,348,278 Debt instruments 48,367,791 49,963,947 4,425,723 17,486,057 28,052,167 Total 575,073,521 579,840,767 24,574,448 81,508,836 473,757,483 12/31/2019 Assets Accounting Value Fair Value Level 1 Level 2 Level 3 Cash and Balances With The Brazilian Central Bank 15,249,515 15,249,515 - 15,249,515 - Financial Assets Measured At Amortized Cost Loans and amounts due from credit institutions 109,233,128 109,233,128 - 109,233,128 - Loans and advances to customers 326,699,480 327,278,243 - - 327,278,243 Debt instruments 38,748,296 39,678,192 5,378,791 7,858,612 26,440,789 Total 489,930,419 491,439,078 5,378,791 132,341,255 353,719,032 2018 Assets Accounting Value Fair Value Level 1 Level 2 Level 3 Cash and Balances With The Brazilian Central Bank 15,228,491 15,269,809 - 15,269,809 - Financial Assets Measured At Amortized Cost: Loans and other amounts with credit institutions 91,859,759 91,859,759 - 91,859,759 - Loans and advances to customers 301,702,207 303,495,240 - - 303,495,240 Financial assets measured at amortized cost - Debt instruments 36,799,509 38,927,356 9,766,162 29,161,194 - Total 433,337,208 437,299,602 9,766,162 124,038,200 303,495,240 ii) Financial liabilities measured at other than fair value Following is a comparison of the carrying amounts of Bank´s financial liabilities measured by a value other than fair value and their respective fair values on December 31, 2020, 2019 and 2018: During 2020, The Bank reclassified R$ 73,075,341 of “Deposits of Brazil's Central Bank and deposits of credit institutions” and R$ 390,760,088 of “Customer deposits” from level 2 to level 3, as there was no active trading market for these instruments.” 12/31/2020 Liabilities Accounting Value Fair Value Level 1 Level 2 Level 3 Financial Liabilities at Measured Amortized Cost: Deposits of Brazil's Central Bank and deposits of credit institutions 131,656,962 131,654,431 - 58,579,090 73,075,341 Customer deposits 445,813,972 445,856,090 - 55,096,002 390,760,088 Marketable debt securities 56,875,514 57,265,307 - - 57,265,307 Debt instruments Eligible Capital 13,119,660 13,119,660 - - 13,119,660 Other financial liabilities 59,822,683 59,822,683 - - 59,822,683 Total 707,288,791 707,718,171 - 113,675,092 594,043,080 12/31/2019 Liabilities Accounting Value Fair Value Level 1 Level 2 Level 3 Financial Liabilities at Measured Amortized Cost: Deposits of Brazil's Central Bank and deposits of credit institutions 99,271,415 99,271,415 - 99,271,415 - Customer deposits 336,514,597 336,593,455 - 336,593,455 - Marketable debt securities 73,702,474 73,889,348 - 10,205,065 63,684,284 Subordinated Debt 10,175,961 10,175,961 - 10,175,961 - Other financial liabilities 55,565,954 55,565,954 - - 55,565,954 Total 575,230,401 575,496,133 - 456,245,896 119,250,238 12/31/2018 Liabilities Accounting Value Fair Value Level 1 Level 2 Level 3 Financial Liabilities at Measured Amortized Cost: Deposits of Brazil's Central Bank and deposits of credit institutions 99,022,806 99,022,806 - 99,022,806 - Customer deposits 304,197,800 304,197,800 - 304,197,800 - Marketable debt securities 74,626,232 74,626,232 - 4,599,204 70,027,028 Subordinated Debt 9,885,607 9,885,607 - 9,885,607 - Debt Instruments Eligible to Compose Capital 9,779,944 9,779,944 9,779,944 - Other financial liabilities 49,782,780 49,782,780 - - 49,782,780 Total 547,295,169 547,295,169 - 427,485,361 119,809,808 The methods and assumptions used to estimate the fair values summarized in the tables above are set forth below: - Loans and amounts due from credit institutions and from clients – Fair value are estimated for groups of loans with similar characteristics. The fair value was measured by discounting estimated cash flow using the average interest rate of new contracts. That is, the future cash flow of the current loan portfolio is estimated using the contractual rates, and then the new loans spread over the risk free interest rate are incorporated to the risk free yield curve in order to calculate the loan portfolio fair value. In terms of behavior assumptions, it is important to highlight that a prepayment rate is applied to the loan portfolio, thus a more realistic future cash flow is achieved. - Deposits from Bacen and credit institutions and Client deposits – The fair value of deposits was calculated by discounting the difference between the cash flows on a contractual basis and current market rates for instruments with similar maturities. For variable-rate deposits, the carrying amount was considered to approximates fair value. - Debt and Subordinated Securities and Debt Instruments Eligible to Compose Capital – The fair value of long-term loans were estimated by cash flow discounted at the interest rate offered on the market with similar terms and maturities. The valuation techniques used to estimate each level are defined in note 2.e.

As required, the “maximum potential amount of future payments” represents the notional amounts that could be considered as a loss if there were a total default by the guaranteed parties, without consideration of possible recoveries from collateral held or pledged, or recoveries under recourse provisions. There is no relationship between these amounts and probable losses on these guarantees, In fact, "maximum potential amount of future payments" significantly exceeds inherent losses.

Financial guarantees are provided to Bank´s clients in respect of their obligations to third parties. The Bank has the right to seek reimbursement from the clients for any amount it shall have to pay under such guarantee. Additionally, the Bank may hold cash or other highly liquid collateral for these guarantees. These guarantees are subject to the same credit evaluation performed on the origination of loans. The Bank´s expectation is that many of these guarantees to expire without the need of cash disbursement in advance. Therefore, in the ordinary course of business, the Bank expects that these guarantees will have virtually no impact on its liquidity. Performance guarantees are issued to guaranteed clients obligations such as to make contractually specified investments, to supply specified products, commodities, or maintenance or warranty services to a third party, completion of projects in accordance with contract terms, etc. Financial standby letters of credit include guarantees of payment of loans, credit facilities, promissory notes and trade acceptances. The Bank always requires collateral to grant this kind of financial guarantees. In Documentary Credits, the Bank acts as a payment intermediary between trading companies located in different countries (import-export transactions). Under a documentary credit transaction, the parties involved deal with the documents rather than the commodities to which the documents may relate. Usually the traded commodities are used as collateral to the transaction and the Bank may provide some credit facilities. Loan commitments draw able by third parties include mostly credit card lines and commercial commitments. Credit card lines are unconditionally cancelable by the issuer. Commercial commitments are mostly 1 year facilities subject to information requirements to be provided by Banks´s clients. The risk criteria followed to issue all kinds of guarantees, financial standby letters of credit, documentary credits and any risks of signature are in general the same as those used for other products of credit risk, and therefore subject to the same admission and monitoring standards. The guarantees granted on behalf of Bank´s clients are subject to the same credit quality review process as any other risk product. On a regular basis, at least once a year, the solvency of the mentioned clients is checked as well as the probability of those guarantees to be executed. In case that any doubt on the client’s solvency may arise we create allowances with charge to net income, by the amount of the inherent losses even if there is no claim to us. The provision for losses on the non-recovery guarantees and other securities (Note 9.c) is recorded as "Impairment losses on financial assets (net)” on consolidated income statement and its calculation is described in note 2.i. Additionally, the liability recognized as deferred revenue for the premium received for providing the above guarantees, which is being amortized into income over the life of the related guarantees is R$356,226 (2019 - R$285,218 and 2018 - R$330,018). b) Off-balance funds under management Banco Santander has under its management investment funds for which it does not hold any substantial participation interests and does not act as principal over the funds, and it does not own any shares of such funds. Based on the contractual relationship governing the management of such funds, third parties who hold the participation interests in such funds are those who are exposed to, or have rights, to variable returns and have the ability to affect those returns through power over the fund. Moreover, though Santander Brasil acts as fund manager, in analyzing the fund manager’s remuneration regime, the remuneration regime is proportionate to the service rendered, and therefore does not create exposure of such importance to indicate that the fund manager is acting as the principal (Note 2.w). The funds managed by Banco Santander not recorded in the balance sheet are as follows: Thousand of reais 2020 2019 2018 Funds under management 2,716,477 2,034,999 1,896,689 Managed Funds 191,873,169 230,199,261 200,366,261 Total 194,589,646 232,234,260 202,262,950 c) Third-party securities held in custody On December 31, 2020, the Bank held in custody debt securities and equity instruments totaling R$35,519,498 (2019 - R$27,283,548 e 2018 - R$34,040,742) entrusted to it by third parties which are off-balance instruments. d) Residual maturity The breakdown, by maturity, of the balances of certain items in the consolidated balance sheets is as follows: 2020 Thousand of reais On Up to 3 to 1 to 3 to After 5 Total Assets: Cash and balances with the Brazilian Central Bank 7,373,662 12,775,063 -

Monthly rental contracts will be adjusted on an annual basis, as per prevailing legislation, at Índice Geral de Preços do Mercado (IGPM) variation. The lessee is entitled to unilaterally rescind the agreement, at any time, as contractual clauses and legislation. g) Contingent assets On December 31, 2020, 2019 and 2018 no contingent assets were recorded. h) COVID-19 The Bank monitors the effects of this pandemic that affect its operations and that may adversely affect its results. Since the beginning of the pandemic in Brazil, Committees have been set up to monitor the effects of the spread and its impacts, in addition to government actions to mitigate the effects of COVID-19. The Bank maintains its operational activities, observing the protocols of the Ministry of Health and other Authorities. Among the actions taken, we highlight (a) the dismissal of employees from the risk group and intensification of work in the home office, (b) the definition of a follow-up protocol, with health professionals, for employees and family members who have the symptoms of COVID19 and (c) increased communication about preventive measures and remote means of care. The Federal Government through the National Monetary Council and the Central Bank of Brazil has adopted measures to mitigate the impacts caused by COVID-19, specifically on credit operations, fundraising, reduction of reserve requirements and aspects related to capital, such as ( a) measures to facilitate the renegotiation of credit operations without an increase in provisions, (b) a reduction in capital requirements, in order to expand the credit system's ability to grant credit and (c) a reduction in reserve requirements. , to improve liquidity conditions. The Bank, aware of its responsibilities, made adjustments to its policies in order to respond to the COVID-19 pandemic and adopted measures such as those shown below: • Extensions for individuals were granted with a 2-month grace period with the possibility of extension for another month. • In the case of a legal entity, extensions were granted with a grace period of up to 6 months in line with BNDES (National Bank for Economic and Social Development). The extensions were granted from March to September 2020. Throughout 2020, the position of extensions in response to the Pandemic COVID-19 reached 1,728,197 customers, R$ 40,592 million in extended credit, equivalent to 9.72% of the total credit portfolio, as shown below: Thousand of reais Total Extended Portfolio Of which: expired Total Portfolio % Portfolio Extended Commercial and industrial 11,277,454 8,876,863 191,281,653 5.90% Mortgage loans - construction 14,061,449 13,569,186 45,791,869 30.71% Loans to individuals 15,193,901 15,062,757 178,652,145 8.50% Leasing 59,404 29,388 2,096,359 2.83% Total* 40,592,207 37,538,194 417,822,027 9.72% * The total portfolio excludes exposures not accounted for in the balance sheet Of the total extensions expired on December 31, 2020 of R$37,538 million, R$28,348 million were in stage 1, R$6,608 million in stage 2 and R$2,567 million in stage 3. The scenario of uncertainties caused by the Pandemic COVID-19 brought an increase in expected losses, for which continuous monitoring has been maintained. In response, in 2020, the Bank constituted an additional provision in the amount of R$3,200,000 (R$1,411,000 in stage 1, R$1,120,000 in stage 2 and R$669,000 in stage 3). This provision was calculated based on the analysis of the potential macroeconomic effects and took into account not only quantitative and qualitative indicators, but also the adequate and accurate identification of risks and a collective assessment of exposures. For the expected losses estimation, prospective information is taken into account. Santander Brazil considers three macroeconomic scenarios, periodically updated. The evolution for a period of five years of the main macroeconomic indicators used to estimate the expected losses in Santander Brazil is as follows (before pandemic impacts): Pessimistic Scenarios Base Scenarios Optimistic Scenarios Variables 2020 2021 2022 2023 2024 2020 2021 2022 2023 2024 2020 2021 2022 2023 2024 Interest Rate 7.0% 9.5% 9.0% 9.0% 9.0% 4.5% 5.5% 6.0% 6.0% 6.0% 3.5% 3.8% 5.0% 5.0% 5.0% Unemployment Rate 12.8% 15.9% 17.7% 18.2% 17.9% 10.8% 10.2% 9.7% 8.8% 8.5% 10.1% 8.9% 7.8% 6.8% 6.6% Housing Price Change -2.3% -2.4% -1.2% -0.3% 0.0% 0.8% 2.1% 3.6% 3.5% 3.5% 2.5% 7.2% 7.7% 7.3% 7.3% GDP Growth -3.0% -3.3% -1.7% -0.9% 1.9% 2.3% 2.2% 2.4% 2.5% 2.5% 4.4% 5.0% 4.6% 4.5% 3.7% Burden Income 21.0% 21.5% 22.0% 22.0% 22.0% 20.4% 20.4% 20.4% 20.4% 20.4% 19.5% 19.0% 18.8% 18.9% 18.9% Each macroeconomic scenario is associated with a determined likelihood of occurrence.

Business Segment Reporting
44. Business segment reporting	44. Business segment reporting In accordance with IFRS 8, an operating segment is a component of an entity: (a) that engages in business activities from which it may earn revenues and incur expenses (including revenues and expenses relating to transactions with other components of the same entity), (b) whose operating results are regularly reviewed by the entity’s management responsible to make decisions about resources to be allocated to the segment and assess its performance, and (c) For which different financial information are available. Based on these guidelines, the Bank has identified the following reportable operating segments: • Commercial Banking. • Global Wholesale Banking.

Risk Management
46. Risk management	46. Risk management Risk management at Banco Santander is based on the following principles: A. Independence of the management activities related to the business; B. Involvement of the senior management in decision-making; C. Consensus in the decision making on credit operations between the Risk and Business departments; D. Collegiate decision-making, which includes the branch network, aiming to encourage diversity of opinions and avoiding the attribution of individual decisions; E. The use of statistical tools to estimate default, which includes internal rating, credit scoring and behavior scoring, RORAC (Return on Risk Adjusted Capital), VaR (Value at Risk), economic capital, scenario assessment, among others; F. Global approach, which an integrated treatment of risk factors in the business departments and the concept of economic capital as a consistent metric for risk undertaken and for business management; G. Common management tools H. Organizational structure I. Scopes and responsibilities J. Risk limitation K. Recognition L. Effective information channel M. Maintenance of a medium-low risk profile, and low volatility by: • The portfolio diversification, limiting concentration in clients, groups, sectors, products or geographically speaking; the complexity level of market operations reduction; the analysis of social and environmental risks of businesses and projects financed by the bank; continuous follow up to prevent the portfolios from deteriorating. • Policies and procedures definition that are part of the Regulatory Framework Risk, which regulates the risk activities and processes. They follow the instructions of the Board of Directors, the regulations of the BACEN and the international best practices in order to protect the capital and ensure business' profitability. At Banco Santander, the risk management and control process is structured using as reference the framework defined at corporate level and described according to the following phases: I. Adaptation of corporate management frameworks and policies that reflect Banco Santander’s risk management principles. Within this regulatory framework, the corporate risk management framework, regulates the principles and standards governing Banco Santander´s risk activities, based on the corporate organization and a management models, meeting the necessary regulatory requirements for credit management. The organizational model comprises the management map, which defines the risk function and governance, and the regulatory framework itself. II. Identification of risks through the constant review and monitoring of exposures, the assessment of new products, businesses and deals (singular transactions); III. Risks measurement using methods and models periodically tested. IV. Preparation and distribution of a complete set of reports that are reviewed daily by the heads at all levels of Banco Santander management. V. Implementation of a risk control system which checks, on a daily basis, the degree to which the Bank´s risk profile matches the risk policies approved and the risk limits set. The most noteworthy corporate tools and techniques (aforementioned) already in use at Banco Santander are in different stages of maturity regarding the level of implementation and use in the Bank. For wholesale segment, these techniques are in line with the corporate level development. For local segments, internal ratings and scorings based models, VaR and market risk scenario analysis and stress testing were already embedded in risk management routine while Expected loss, Economic Capital and RORAC have been integrated in risk management. VI. Internal ratings- and scorings-based models which, by assessing the various qualitative and quantitative risk components by client and transaction, making it possible to estimate, firstly, the probability of default and, subsequently, the expected loss, based on Loss Given Default (LGD) estimates. VII. Economic capital, as a homogeneous measurement of the assumed risk and the basis for the measurement of the performance management. VIII. RORAC, used both as a transaction pricing tool in the whole sale segment (more precisely in global ranking and markets - bottom-up approach) as for in the analysis of portfolios and units (top-down approach). IX. VaR, which is used for controlling and setting the market risk limits for the various treasury portfolios. X. Scenario analysis and stress testing to supplement the analysis market and credit risk in order to assess the impact of alternative scenarios, even over provisions and capital. a) Corporate Governance of the Risk Function The structure of Banco Santander’s Risk Committee is defined in accordance with the highest standards of prudent management, while respecting local legal and regulatory environment. Its main responsibilities are: A. Integrate and adapt the Bank's risk to local level, further than the risk management strategy, tolerance level and predisposition to the risk, previously approved by the executive committee and board of directors, all matched with corporate standards of Banco Santander Spain; B. Approve the proposals, operations and limits of clients and portfolio; C. Regularly monitor all the risks inherent to the business, proving if your profile is adequate to what was established in the risk appetite. D. Authorize the use of management tools and local risk models and being aware of the result of their internal validation. E. Keeping updated, assessing and monitoring any observations and recommendations periodically formulated by the supervisory authorities regarding their functions. The credit risk management structure is made up of departments that operate from the point of view of portfolio management and credit analysis and decision nuclei in an individualized way in Individuals, Companies and Wholesale. A specific area's mission is to consolidate portfolios and their respective risks, subsidizing management, as well as the Group's headquarters in Spain, with an integrated view of risks. The credit risk management structure is made up of departments that operate from the point of view of managing the retail and wholesale portfolios. A specific area's mission is to consolidate portfolios and their respective risks, subsidizing management, as well as the Group's headquarters in Spain, with an integrated view of risks. A specific structure is responsible for serving internal and external regulators, supervisors and auditors. It has a core called ERM-Enterprise risk management, integrated by a set of functions, transversal to all risks, necessary for its adequate management. The areas of Methodology (development and parameterization of models) are part of this structure; Decision Engines; Credit Risk Control; Risk Control and Performance covering Risk Culture); Integrated management and Relationship with Supervisors and Local Provision & IFRS9. b) Credit Risk b.1) Introduction to the treatment of credit risk The credit risk management provides subsidies to define strategies as risk appetite, to establish limits, including exposure analysis and trends as well as the effectiveness of the credit policy. The goal is to maintain a risk profile and adequate minimum profitability to offset the estimated default, both client and portfolio, as defined by the Executive Committee and Board of Directors. Additionally, it is responsible for the risk management systems applied in the identification, measurement, control and reduction of exposure to risk in individual or clustered by similar operations. The risk management is specialized according to each clients' characteristics, being segregated between individual clients (with the accompanied of dedicated analysts) and customers with similar characteristics (standardized). • Individualized management: It is performed by a defined risk analyst, which prepares the analysis, and forwards it to the Risk Committee and monitors the client's progress. It covers the Wholesale segment clients (Corporate and GB&M), Retail (Companies 3 and Governments, Institutions and Universities); • Standardized management: Aimed at individuals and companies not classified as individualized clients. Based on automated models of decision-making and internal risk assessment, complemented by commercial heave and analysts specialized teams to handle exceptions. Macroeconomic aspects and market conditions, sectored and geographical concentration, as well as client profiling and economic prospects are also evaluated and considered in the appropriate measuring of credit risk. b.2) Measures and measurement tools Rating tools The Bank uses proprietary internal rating models to measure the credit quality of a given customer or transaction. Each rating relates to a certain probability of default or non-payment, determined on the basis of the customer's historical experience, to predict default. Rating/Scores models are used in the Bank’s loan approval and risk monitoring process. The classification of loans into different categories is made according to the analysis of economic and financial situation of the client and any other registratered information updated frequently. New modes of operation are subject to credit risk evaluation, verification and adaptation to the controls adopted by the Bank. Ratings assigned to customers are reviewed periodically to include any new financial information available and the experience in the Banking relationship. The frequency of the reviews is increased in case of customers that reach certain levels in the automatic warning systems and of customers classified as requiring special monitoring. The own rating tools are monitored and reviewed to qualifications by them awarded are progressively enhanced. Credit risk parameters The estimative of the risk parameters Probability of Default (PD) and Loss Given Default (LGD) are based on internal experience, i.e. on default observations and on the experience in defaulted loan recoveries during a defined credit cycle. For low risk portfolios, such as banks, sovereign risk or global wholesale clients, the parameters are based on CDS market data and with global broadness, using Group Santander´s world presence. For the other portfolios, parameter estimative are based on the Bank’s internal experience. In addition to the Probability of Default (PD), the Bank is managing its credit portfolio, seeking to make loans to borrowers that have higher volumes of guarantees associated with the operations and also works constantly on strengthening its credit recovery department. These and other actions combined, are responsible for ensuring the adequacy of LGD parameters (Loss Given Default, the loss resulting from the borrower's default event to honor the principal and/or interest payments). LGD calculation is based on net losses of non-performing loans, considering the guarantees associated with the transaction, revenues and expenses related to the recovery process and also the timing default. Besides that, the Loss identification period, or “LIP,” is also considered in the estimation of the risk parameters that is represented by the time period between the occurrence of a loss event and the identification of an objective evidence of this loss. In other words, it represents the time horizon from the credit loss occurrence until the effective confirmation of such loss. The Bank use proprietary internal rating models to measure the credit quality of a given client or transaction. Each rating relates to a certain probability of default or non-payment, determined on the basis of the client's history, with the exception of certain portfolios classified as “low default portfolios”. These ratings and models are used in loan approval and risk monitoring processes. The table shown in note 9.b shows the portfolio by the internal risk rating levels and their probability of default.

Periodically conduct tests in order to monitor and maintain control over credit risk. To complement the use of admission and rating, the Bank use other measures that supports the prudent and effective management of credit risk, based on the loss observed. The cost of credit is measured by the sum of credit losses and to the average loans portfolio of the same year. b.4) Credit risk cycle Banco Santander has a global view of its credit portfolio throughout the various phases of the risk cycle, with a level of detail that allows us to evaluate the current situation of risk and any movements. This mapping is followed by the Board of Directors and the Executive Committee of the bank that no only sets policies and risk procedures, limits and delegates responsibilities. It also approves and supervises the activities of the area. The risk management process consists of identifying, measuring, analyzing, controlling, negotiating and deciding on, as appropriate, the risks incurred in the Bank’s operations and companies of the conglomerate. The risk cycle comprises three different phases: • Pre-sale: this phase includes the risk planning and setting targets, determination of the Bank’s risk appetite, approval of new products, risk analysis and credit rating process, and limit setting. • Sale: this is the decision-making phase for both pre-classified and specific transactions. • Post-sale: this phase comprises the risk monitoring, measurement and control processes and the recovery process. Planning and setting risk limits Risk limit setting is a dynamic process that identifies Banco Santander’s risk appetite by assessing business proposals and its risk attitude. This process is defined through the risk appetite approved by the Bank's management and the units. In the case of individualized risks, the most basic level is the customer, for which individual limits are set. For GCB clients, a pre-classification model is used based on a system of measurement and monitoring of economic capital. In relation to the Corporate segment, the operational limit model is used in maximum nominal credit amounts. To the risks of customers with standardized management, the limits of the portfolios are planned using credit management programs (SGP) agreed document for the areas of business and risks, and approved by the Executive Committee. This document contains the results expected for the business in terms of risk and return, beyond the limits which govern the activity and risk management. This client group has a more automated treatment in risks. Risk analysis and rating process Risk analysis is a pre-requisite for the approval of loans to clients by the Bank. This analysis consists of examining the counterparty’s ability on meeting its contractual obligations to the Banco Santander, which involves analyzing the client’s credit quality, its risk transactions, solvency, and sustainability of business and the return to be obtained in view of the risk assumed. The risk analysis is conducted annually, at least, and can be held shortly when client profile indicates (through systems with centralized alerts, managers visits to clients or specific credit analysis), or when operations are not covered by pre-classification. Decision-Making on Operations The process of decision making on operations aims to analyze and adopt adopt in accordance with pre-established policies, taking into account risk appetite and any elements of the operation that are important in assessing risk and return. The Banco Santander uses, among others, the RORAC methodology (profitability on risk-adjusted capital), for risk analysis and pricing in the decision-making process on transactions and deals. Risk monitoring and control In Individual retail, customers are systematically reviewed through a daily credit rating process. This process allows for revaluations in credit exposure, allowing increases in exposure for customers with good credit quality. In case of detection of deterioration in the level of risk, actions are automatically generated to contain credit risk and preventive actions. In the case of individualized management, the preventive detection of deterioration in the credit quality of the operation is the responsibility of the commercial manager in conjunction with the risk analyst. Additionally, risk monitoring is carried out through a permanent observation process for early identification of incidents that may occur in the evolution of operations, customers and their environment. This monitoring process may result in the client’s classification in SCAN. This is a system which allows the differentiation of the management level and the action to be taken case-by-case. Risk control function The control function is performed by assessing risks from various complementary perspectives, the main pillars are the control by geographical location, business area, management model, product and process, facilitating thus the detection of specific areas requiring measures for which decisions should be taken. To obtain an overview of the bank's loan portfolio over the various phases of the credit cycle, with a level of detail that allows the assessment of the current risk situation and any movements. Any changes in the Bank’s risk exposure are controlled on an ongoing and systematic basis. The impacts of these changes in certain future situations, both of an exogenous nature and those arising from strategic decisions, are assessed in order to establish measures that place the profile and amount of the loss portfolio within the parameters set by Executive Commission. b.5) Credit recovery "Strategies and action channels are defined according to the days of past due loans and the amounts, that result in a Map of Responsibilities and always look as the first alternative, the client's recovery. The Bank uses tools as behavioral scoring to study the collection performance of certain groups, in order to reduce costs and increase recoveries. These models seek to measure the probability of clients becoming overdue adjusting collection efforts so that clients less likely to recover, receive timely actions. In cases the payments is most likely to happen, the focus is given in maintaining a healthy relationship with clients. All clients with severe or rescheduled credits delays values have internal restrictions. Clients with high risk index have a model of recovery, with a commercial follow-up and a recovery specialist. b.6) Credit risk from other perspective Certain areas and specific views of credit risk deserve a specialist’s attention, complementary to global risk management. Concentration risk Concentration risk is an essential factor to be analyzed in the area of credit risk management. The Bank constantly monitors the degree of concentration of its credit risk portfolios, by economic sector, geographical area/country, product and client group. The risk committee establishes the risk policies and reviews the exposure limits required to ensure adequate management of credit risk portfolio concentration. From the sectorial standpoint, the distribution of the corporate portfolio is adequately diversified. The Executive Vice-Presidence of Risks works closely with the Executive Vice-Presidence of Financial Strategic in the credit portfolio management, which includes reducing the concentration of exposures through several techniques, such as the arrangement of guarantees to mitigate the companies risk, credit derivatives for hedge purposes or the performance of securitization transactions, in order to optimize the risk/return ratio of the total portfolio. Credit risk from financial market operations This heading includes the credit risk arising in treasury operations with clients, mainly credit institutions. These operations are performed both via money market financing products with different financial institutions and via derivative instruments arranged for the purpose of serving our clients. Risk control is performed using an integrated, real-time system that enables the Bank to know at any time the unused exposure limit with respect to any counterparty, any product and maturity and at any Bank unit. Credit risk is measured at its current market value and its potential value (exposure value considering the future variation in the underlying market factors). Therefore, the equivalent credit risk (CRE) is defined as the sum of net replacement value plus the maximum potential value of the contracts in the future. Environmental risk The Banco Santander's Social and Environmental Responsibility Policy (PRSA), which follows the guidelines of CMN Resolution 3232/2014 and the SARB Regulation Nº. 14 of Febraban, establishes guidelines and consolidates specific policies for socio-environmental practices in business and in relationships with stakeholders. These practices include the management of socio-environmental risks, impacts and opportunities related to topics such as adequacy in credit granting and use, supplier management and socio-environmental risk analysis, which is carried out through the analysis of clients' socio-environmental practices. and Varejo, of the Corporate segment 3 (one of the Corporate Retail segments of the Bank), which have limits or credit risk above R$ 5 million and which are part of the 14 socio-environmental care sectors. In this case, the socio-environmental risk is analyzed in order to mitigate the issues of operational risk, capital risk, credit risk and reputational risk. Since 2009, Santander has been a signatory to the Equator Principles and this set of guidelines is used to mitigate socio-environmental risks in the financing of large projects. The mitigation of socioenvironmental risks in financing large projects is carried out based on analyzes based on the guidelines of the Equator Principles, a set of socioenvironmental criteria referenced in the International Finance Corporation (IFC) Performance Standards on Social and Environmental Sustainability and the Environmental Guidelines, Health and Safety of the World Bank Group. The commitments assumed in the PRSA are detailed in other Bank policies, such as the Anti-Corruption Policy, Supplier Relationships and Homologation Policies and Social and Environmental Risk Policies, as well as the Private Social Investment Policy, which aims to guide the strategy in this area. and to present guidelines for social programs that strengthen this strategy. b.7) Credit management - Main changes The business trends observed in the year 2020 were consistent with the trends presented 2019, where in a challenging economic scenario. The Bank maintained the good quality of its business and did not presented major variances in its delinquency ratios. In December 2020, this ratio achieved 5.55% compared to 6.75% of December 2019 and 6.98%, of December, 2018. Below is a table showing the evolution of the main credit indicators. 2020 2019 2018 Credit risk exposure - customers (Thousand of Reais) 466,104,042 391,569,227 364,193,664 Loans and advances to customers, gross (note 9) 417,822,026 347,256,660 321,933,190 Contingent Liabilities - Guarantees and other sureties (note 43,a) 48,282,016 44,312,567 42,260,474 Non-performing loans ratio (%) - unaudited 5.55% 6.75% 6.98% Impairment coverage ratio (%) - unaudited 110.64% 96.58% 102.42% Specific credit loss provisions, net of RAWO (*) (Thousand of Reais) - unaudited 25,640,489 22,625,750 22,969,315 Cost of credit (% of risk) - unaudited 4.35% 3.93% 3.90% Data prepared on the basis of management criteria and the accounting criteria of the controller unit. (*) RAWO = Recoveries of Assets Derecognized. The Bank incorporates information about the future both in its assessment if the credit risk of an instrument has increased substantially since the initial recognition and in its measurement of the expected credit losses. Based on guidance from its internal committees and economic experts and considering a range of actual and anticipated external information, the Bank develops a base scenario as well as other possible scenarios. This process involves the projection of two or more additional economic scenarios and considers the respective probabilities of each result. External information includes economic data and forecasts published by government agencies and monetary authorities and selected private sector analysts and academics. The base case represents the most likely result and is in line with the information used by the Bank for other purposes, such as strategic planning and budgeting. The other scenarios represent more optimistic and pessimistic results. Periodically, the Bank conducts more extreme stress tests to adjust its determination of these other representative scenarios. 12/31/2020 In Reais Million Over-collateralized assets Under-collateralized assets Carrying value of the assets Fair value of collateral % collateral coverage Carrying value of the assets Fair value of collateral % collateral coverage Individuals (1) 57,633 182,430 317% 3,091 2,756 89% Mortgages 45,746 100,201 219% 46 38 83% Very small, small and middle-market companies, corporates and foreign loans (2) 41,428 143,168 346% 56,052 42,728 76% Total 144,807 425,799 294% 59,188 45,522 77% (1) Vehicles and others loans.

The Bank operates according to global policies, within the Group’s risk tolerance level, aligned with the objectives in Brazil and in the world. With this purpose, it has developed its own Risk management model, according to the following principles: · Functional independence; · Executive capacity sustained by knowledge and proximity with the client; · Global reach of the function (different types of risks); · Collective decision-making, that evaluates a variety of possible scenarios and do not compromise the results with individual decision (including Brazil Executive Risk Committee - Comitê Executivo de Riscos Brasil). This Comitee delimits and approves the operations. The Asset and Liabilities Committee, which responds for the capital management and structural risks, including country-risk, liquidity and interest rates. · Management and improvement of the equation risk/return; and · Advanced methodologies for risk management, such as Value at Risk – VaR (historical simulation of 521 days with a confidence level of 99% and time horizon of one day), scenarios, financial margin sensibility, equity value and contingency plan. The Market Risks structure is part of the Vice Presidency of Credit and Market Risks, an independent area that applies risk policies taking into consideration the guidelines of the Board of Directors and the Risks Division of Santander in Spain. c.1) Activities subject to market risk The measurement, control and monitoring of the market risk area comprises all operations in which net worth risk is assumed. This risk arises from changes in the risk factors –interest rate, exchange rate, equities, commodity prices and the volatility thereof– and from the solvency and liquidity risk of the various products and markets in which the Bank operates. The activities are segmented by risk type as follows: I. Trading: this item includes financial services for clients, trading operations and positioning mainly in fixed-income, equity , foreign currency products and shares. II. Balance sheets management: A risk management assessment aims to give stability to interest income from the commercial and economic value of the Bank, maintaining adequate levels of liquidity and solvency. The risk is measured by the balance sheets exposure to movements in interest rates and level of liquidity. III. Structural risks: · Structural foreign currency risk/hedges of results: foreign currency risk arising from the currency in which investments in consolidable and non-consolidable companies are made (structural exchange rate). This item also includes the positions taken to hedge the foreign currency risk on future results generated in currencies other than the Real (hedges of results). · Structural equities risk: this item includes equity investments in non-consolidated financial and non-financial companies that give rise to equities risk. The Financial management area is responsible for the balance sheet management risk and structural risks through the application of uniform methodologies adapted to the situation of each market in which the Bank operates. Thus, in the convertible currencies area, Financial management directly manages the Parent's risks and coordinates the management of the other units operating in these currencies. Decisions affecting the management of these risks are taken through the ALCO (Asset Liability Control committees) in the respective countries. The Financial management goal is to ensure the stability and recurring nature of both the net interest margin of the commercial activity and the Bank’s economic value, whilst maintaining adequate liquidity and solvency levels. Each of these activities is measured and analyzed using different tools in order to reflect their risk profiles as accurately as possible. Interest rate Risk The following table aggregates by product the cash flows of the operations of our perimeter of companies that have interest income. The transactions are presented by the book balance at the closing date of the years 2020, 2019 and 2018. It is not associated with the risk management of changes in interest rates or indexer mismatches, which is done by monitoring metrics of Marketplace. However, it allows to evaluate the concentrations of term and possible risks and below it, the balances of the same products are presented at the redemption value at maturity, except for the line dealing with receivables and obligations linked to derivative contracts. 2020 In millions of Reais Position of Accounts Subject to Interest Rate Risk 0 to 30 days 31 to 180 days 181 to 365 days 1 to 5 days Above 5 years Total Remunerated Assets: Financial assets measured at fair value in income - 153 50 250 1,747 2,200 Debt Instruments - 153 50 250 1,747 2,200 Equity Instruments - - - - - - Derivatives - - -

Such criteria differ in certain aspects from those adopted under BRGAAP, which uses the regulatory limits defined by the Central Bank (Bacen), in addition to the difference in the scope of the calculation basis for these losses, which for IFRS purposes considers assets other than those provided by Bacen. b) Categories of financial assets As detailed in the accounting practices note, IFRS9 provides for the definition of the business models associated with each portfolio, as well as the performance of the SPPI test - if the returns of that asset are exclusively principal and interest, for classification in the categories of financial assets. BRGAAP provides for certain differences in the categorization of these financial assets, as well as establishing as an indicator the management's intention for classification to be made. The criteria for reclassification between categories are also different between the two accounting practices. c) Deferral of financial fees, commissions and other costs under effective interest rate method: Under IFRS, financial fees, commissions and other costs that are integral part of effective interest rate of financial instruments measured at amortized cost are recognized in the income statement over the term of the corresponding contracts. Under BRGAAP these fees and expenses are recognized directly as income when received or paid. d) Reversal of goodwill amortization: Under BRGAAP, goodwill is systematically amortized over a period of up to 10 years, subject to the impairment test at least once a year or in a shorter period, in the event of any additional evidence. Under IFRS, in accordance with IAS 38 “Intangible Assets”, goodwill is not amortized, but instead, is tested for impairment, at least annually, and whenever there is an indication that the goodwill may be impaired. The tax amortization of goodwill of Banco ABN Amro Real SA represents a difference between book and tax basis of a permanent nature and definitive as the possibility of future use of resources to settle a tax liability is considered remote by management, supported by the opinion of expert external advisors. The tax amortization of goodwill is permanent and definitive, and therefore does not apply to the recognition of a deferred tax liability in accordance with IAS 12, on temporary differences. e) Realization on purchase price adjustments: As part of the purchase price allocation in acquisitions of an entity, substantially, in the acquisition of Banco Real, following the requirements of IFRS 3, the Bank has recognized the assets and liabilities of the acquiree to fair value, including identifiable intangible assets with finite lives. Under BRGAAP, in a business combination, the assets and liabilities are kept at their book value. This purchase price adjustment relates substantially to the allocation related to the value of assets in the loan portfolio. The initial recognition of value of the loans at fair value, adjustment to the yield curve of the loan portfolio in comparison to its nominal value, which is recognized by its average realization period. f) Recognition of fair value in the partial disposal of investments in subsidiaries Under IFRS 10 "Consolidated Financial Statements" on partial disposal of a permanent investment when control is lost, the fair value is recognized over the remaining portion is remeasured at its fair value, the effect of this update being recognized in result (Webmotors). Under BRGAAP, this type of operation, ongoing participation is registered by its book value. g) Option for Acquisition of Equity Instrument Within the context of transaction, Banco Santander has granted to the members of Getnet S.A. and Banco Olé Consignado a put option over all shares of Getnet S.A. and Banco Olé Consignado held by them. The overall out in IAS 32, a financial liability was recognized for this commitment, with a specific charge in a heading in stockholders' equity in the amount of R$950 million and R$67 million, respectively. Subsequently, the options have been updated and their effect is recognized in income. On December 19, 2018, Banco Santander and the Minority shareholders of Getnet SA entered into an addendum to the Purchase and Sale Agreement for Shares and Other Covenants of Getnet SA, in which Banco Santander committed to acquire all the shares of the Minority Shareholders, corresponding to 11.5% of the share capital of Getnet SA, for the amount of R$1,431,000. The acquisition was approved by BACEN on February 18, 2019 and concluded on February 25, 2019, so that Banco Santander now holds 100% of the shares representing Getnet SA's share capital. On March 14, 2019, the shareholder minority stake in Banco Olé Bonsucesso Consignado SA formalized its interest in exercising the put option provided for in the Investment Agreement, entered into on July 30, 2014, to sell its 40% stake in Olé Consignado to Banco Santander (Brazil) SA On December 20, 2019, the parties entered into a binding agreement for the acquisition, by Banco Santander, of all the shares issued by Bosan Participações SA, for the total amount of R$1.6 billion, to be paid on the closing date of the Operation. On January 30, 2020, the name of Banco Olé from Banco Olé Bonsucesso Consignado SA was changed to Banco Olé Cosignado SA On January 31, 2020, the Bank and the shareholders of Bosan Participações SA concluded the final agreement and signed the purchase and sale of 100% of the shares issued by Bosan, through the transfer of Bosan's shares to the Bank and payment to sellers in the total amount of R$1,608,772,783.47. As a result, the Bank became, directly and indirectly, the holder of 100% of Banco Olé's shares. h) Santander Serviços goodwill (Santusa) According to the IFRS 3 "Business Combination", when the owner acquires more shares or other equity instruments of an entity already controlled, it shall consider such amount as an equity reduction. According to the BRGAAP this amount shall be registered in the asset as goodwill or discount on the acquisition f the investment, which is the difference between the acquision cost and the equity amount of the shares. i) Reclassification of financial instruments at fair value through profit or loss Under BRGAAP, all loans, financing and deposits are recorded at amortized cost. In IFRS, in accordance with IFRS 9 "Financial Instruments: Recognition and Measurement", financial assets may be measured at fair value and included in the category "Other financial assets at fair value through profit or loss", in order to eliminate or significantly reduce accounting mismatches ( accounting mismatch) of recognition or measurement derived from the measurement of assets or liabilities or from the recognition of gains or losses on these assets / liabilities on a number of bases, which are managed and their performances valued at fair value. Accordingly, the Bank classified loans, financing and deposits that meet these parameters as "fair value through profit or loss", as well as certain debt instruments classified as "available for sale" in BRGAAP. The Bank opted for this classification base in IFRS, since it eliminates an accounting mismatch in the recognition of revenues and expenses. j) Reclassification of financial assets measured at fair value through other comprehensive income According to the BRGAAP, the Bank registers some investments, for example, debt instruments initially measured at amortized cost and equity instruments at cost. At the time of this balance sheet, the management reviewed the managing strategy of its investments and according to Bacen Circular 3.068, the debt instruments were reclassified to "trading" measured at fair value with changes in the income statement. According to the IFRS, the Bank is classifying this investments as financial assets measured at fair value through other comprehensive income them at fair value with changes in "other comprehensive income", in line with IAS 9 "Financial Instruments ", which does not allow the reclassification of any financial instrument to fair value with changes in the income statement after the initial recognition.

Description Of Significant Accounting Policies Policies Abstract
a) Foreign currency transactions	a) Foreign currency transactions The financial statements are presented in Brazilian Reais, the functional and reporting currency of Banco Santander and its subsidiaries. The assets and liabilities and foreign subsidiary are converted to Real as follows: - Assets and liabilities are translated at the exchange rate at the balance sheets date. - Revenues and expenses are translated at the monthly average exchange rates. - Gain and losses on translation of net investment are recorded in the statement of comprehensive income, in “exchange rate of investees located abroad”.
b) Basis of consolidation	b) Basis of consolidation i. Subsidiaries “Subsidiaries” are defined as entities over which the Bank has control. Control is based on whether the Bank has: i) power over the investee; ii) exposure, or rights, to variable returns from its involvement with the investee; and iii) the ability to use its power over the investee to affect the amount of the returns, as set forth in the law, the Bylaws or agreement. Consolidation of a subsidiary begins when the Bank obtains control over the subsidiary and ceases when the Bank loses control of the subsidiary. Specifically, income and expense of a subsidiary acquired or disposed during the year are included in the consolidated income statement and other comprehensive income from the date the Bank gains controls until the date when the Bank ceases to control the subsidiary. Profit or loss and each component of Other Comprehensive Income are attributed to the owners of the Bank and to the non-controlling interests even if the effect is attributed to non-controlling interests. Total comprehensive income of subsidiaries is attributed to the owners of the Bank and to the non-controlling interest even if this generates a negative balance for non-controlling interests. All transactions, balances, income and expenses between the companies of the Santander Group are eliminated in the consolidated financial statements. Changes in the Santander Group’s interest in a subsidiary that do not result in loss of control are registered as equity transactions. Any difference between the amount by which the non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to owners of the Company. When the Bank loses control of a subsidiary, the profit or loss on disposal is calculated as the difference between (i) the aggregate 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. Amounts previously recognized in other comprehensive income in relation to the subsidiary are registered (i.e. reclassified to income statement or transferred directly to retained earnings) in the same manner as it would be required if the relevant assets or liabilities are disposed of. The fair value of any investment retained in the former subsidiary at the date when control got lost is considered as the fair value on initial recognition for subsequent accounting under IFRS 9 Financial Instruments: Recognition and Measurement or, when applicable, the costs on initial recognition of an investment in an associate or jointly controlled entity. ii. Interests in joint ventures (jointly controlled entities) and associates Joint ventures mean interests in entities that are not subsidiaries but which are jointly controlled by two or more unrelated entities. This is evidenced by contractual arrangements whereby two or more entities (“ventures”) acquire interests in entities (jointly controlled entities) so that strategic financial and operating decisions affecting the joint venture require the unanimous consent of the ventures. Associates are entities over which the Bank is in a position to exercise significant influence (significant influence is the power to participate in the financial and operating decisions of the investee) but it does not control or has joint control over the investee. In the consolidated financial statements, interest in joint ventures and investments in associates are registered using the equity method, i.e. at the Bank’s share of net assets of the investee, after taking into consideration the dividends received from capital reductions and other related transactions. Relevant information regarding companies registered under the equity method by the Bank is provided in note 11. iii. Business combinations, acquisitions and disposals A business combination means the union of two or more individual business or economic business into one single entity or group of entities and is registered in accordance with IFRS 3 - “Business Combinations”. Business combinations are carried out so that the Bank obtains control over an entity and are recognized for accounting purposes as follow: • The Bank measures the cost of the business combination, defined as the fair value of the assets offered, the liabilities incurred and the equity instruments issued, if any. • The fair values of the assets, liabilities and contingent liabilities of the acquired entity or business, including any intangible assets which might not have been recognized by the acquiree, are estimated at the acquisition date and recognized in the consolidated financial statement. • The excess of the acquisition cost over the fair value of the identifiable net assets acquired are recognized as goodwill (note 13). The excess of fair value of the identifiable net assets over the acquisition cost is an advantageous purchase gain and it is recorded as income on the date of the acquisition. The note 3 includes a description of the most significant transactions carried out in 2020, 2019 and 2018. iv. Investment Funds These include investment funds in which the Santander Group companies hold a substantial interest or the entirety of the interests and are therefore exposed to, or have rights, to variable returns and have the ability to affect those returns through power over the fund, in accordance with IFRS 10 - Consolidated Financial Statements and are therefore, consolidated in these financial statements.
c) Definitions and classification of financial instruments	c) Definitions and classification of financial instruments i. Definitions “Financial instrument” is any contract that gives rise to a financial asset of one entity and, simultaneously, to a financial liability or financial interest of another entity. “Equity instrument” is any agreement that evidences a residual interest in the asset of the issuing entity after deducting all of its liabilities. “Financial derivative” is a financial instrument whose value changes in response to the change in an observable market variable (such as an interest rate, foreign exchange rate, financial instrument price, market index or credit rating), whose initial investment is zero or very small compared with other financial instruments with a similar response to changes in market factors, and which is settled at a future date. “Hybrid financial instruments” are contracts that simultaneously include a non-derivative host contract together with a derivative, known as an embedded derivative, that is not separately transferable and has the effect to make part of the cash flow of the hybrid contract vary similar to a stand-alone derivative. The following transactions are not treated for accounting purposes as financial instruments: • Investments in subsidiaries, jointly controlled entities and associates (note 3&11). • Rights and obligations under employee benefit plans (note 21). 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, cash balances at Central Banks and other deposits on demand, Changes in the fair value of hedged items in portfolio hedges of interest rate risk (asset side), Hedging derivatives and Investments, which are reported separately. Upon initial recognition of an equity instrument not held for trading, the Bank may irrevocably choose to present subsequent changes in fair value through Other Comprehensive Income. This option is made considering each investment individually and was not used by the Bank. In addition, upon initial recognition, the Bank may irrevocably designate at fair value through profit or loss a financial asset that would otherwise meet the measurement requirements at amortized cost or at fair value through Other Comprehensive Income, if such designation eliminate or substantially reduce an accounting mismatch that could exist. This option was not used by the Bank. Financial assets are included for measurement purposes in one of the following categories: • Financial Assets Measured At Fair Value Through Profit Or Loss Held For Trading: • Financial Assets Measured At Fair Value Through Profit Or Loss: • Non-Trading Financial Assets Mandatorily Measured At Fair Value Through Profit Or Loss: this • Financial Assets Measured At Fair Value Through Profit Or Loss: The results rising from changes in fair value are recognized at the Financial Assets Measured At Fair Value Through Other Comprehensive Income line in the Shareholders´ equity except for cumulative impairment losses which are recognized in statement of profit or loss. When the investment is sold or has evidences of decreases on the fair value due to impairment, the previously recognized result at the same Shareholders´ Equity line, mentioned above is reclassified to the statement of profit or loss. • Financial Assets Measured At Amortized Cost: A financial asset is measured at amortized cost if it meets the following conditions and is not designated at fair value through profit or loss: • The asset is maintained within a business model whose objective is to maintain assets in order to receive contractual cash flows; • The contractual terms of the financial asset generate, on specific dates, cash flows that refer exclusively to payments of the principal and interest on the principal amount outstanding; • A debt instrument is measured at fair value through Other Comprehensive Income if it meets the following conditions and is not designated at fair value through profit or loss; • The asset is maintained within a business model whose objective is achieved by receiving contractual cash flows and by selling financial assets; and • The contractual terms of the financial asset generate, on specific dates, cash flows that refer exclusively to payments of the principal and interest on the principal amount outstanding. Business model assessment The Bank assesses the objective of a business model in which an asset is maintained at the portfolio level, as it better reflects how the business is managed and what information is provided to management. The information considered comprises: - Policies and objectives defined for the portfolio and the application of these policies in practice. Including, if the Administration's strategy is focused on earning contractual interest income, maintaining a specific interest rate profile, aligning the duration of the assets; - How the portfolio's performance is assessed and reported to the Bank's management; - The risks that affect the performance of the business model (and the financial assets held within that business model) and how these risks are managed; - How the business managers are remunerated - for example, if the remuneration is based on the fair value of the managed assets or the contractual cash flows received; - The frequency, volume and timing of sales in previous periods, the reasons for such sales and your expectations about future sales. However, information on sales activity is not considered in isolation, but as part of an overall assessment of the objective defined by the Bank to manage financial assets. Financial assets held for trading or managed, whose performance is assessed based on fair value, are measured at fair value through profit or loss, as (i) they are not held to receive contractual cash flows (ii) nor are they held to receive flows contractual cash flow and sell financial assets. Valuation to determine whether contractual cash flows refer exclusively to principal and interest payments For the purposes of this assessment, “principal” is defined as the fair value of the financial asset upon initial recognition. “Interest” is defined as the consideration for the value of the currency over time and for the credit risk associated with the value of the principal outstanding during a specific period and for other basic risks and costs of loans (for example, liquidity risk and administrative costs), as well as the profit margin. When assessing whether contractual cash flows refer exclusively to payments of principal and interest, the Bank considers the contractual terms of the instrument. This includes assessing whether the financial asset contains a contractual term that could change the term or value of the contractual cash flows in a way that would not meet this condition. When carrying out the assessment, the Bank considers: - contingent events that would change the amount and timing of cash flows; - leverage; - advance payment terms and extension; - terms that limit the Bank's right to cash flows from assets; and - resources that modify the consideration of the currency value over time, for example, periodic adjustment of interest rates. iii. Classification of financial assets for presentation purposes Financial assets are classified by nature into the following headings in the consolidated financial statements: • Cash and balances with the Bacen: cash balances and balances receivable on demand relating to deposits with Bacen and credit institutions. • Financial Assets Measured At Amortized Cost: includes the debit balances of all credit and loans granted by the Bank, other than those represented by securities, as well as finance lease receivables and other debit balances of a financial nature in favor of the Bank, such as checks drawn on credit institutions, balances receivable from clearing houses and settlement agencies for transactions on the stock exchange and organized markets, bonds given in cash, capital calls, fees and commissions receivable for financial guarantees and debit balances arising from transactions not originating in banking transactions and services, such as the collection of rentals and similar items. • Loans and other amounts with credit institutions: credit of any nature in the name of financial institutions. • Loans and advances to clients: includes debit balances of all the remaining credit and loans granted by the Bank, including money market operations through centralized counterparties. • Debt instruments: bonds and other securities that represent a debt for their issuer, that generate an interest return, and that are in the form of certificates or book entries. • 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, joint ventures or associates. Investment fund units are included in this item. • Trading derivatives: includes the fair value in favor of the Bank of derivatives which do not form part of hedge accounting. • Hedging derivatives: includes the fair value in favor of the Bank of derivatives designated as hedging instruments in hedge accounting. • Investments in associates and jointly controlled companies: includes the investments made in the share capital of associates and jointly controlled companies. iv. Classification of financial liabilities for measurement purposes Financial liabilities are classified for measurement purposes into one of the following categories: • Financial Assets At Fair Value Through Profit Or Loss Held for Trading: this category includes 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 ("reverse repos") or borrowed (short positions). • Financial Assets At Fair Value Through Profit Or Loss: financial liabilities are included in this category when they provide more relevant information, either because this eliminates or significantly reduces recognition or measurement inconsistencies (accounting mismatches) that would otherwise arise from measuring assets or 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 Group'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 carried on by financial institutions. v. Classification of financial liabilities for presentation purposes Financial liabilities are classified by nature into the following items in the consolidated financial statements: • Deposits from Bacen: deposits of any nature received from Bacen. • Deposits from credit institutions: deposits of any nature, including credit received and money market operations in the name of credit institutions. • Client deposits: includes deposits of any nature such as demand deposits, saving deposits and time deposits including money market operation received from client. • Marketable debt securities: includes the amount of bonds and other debt represented by marketable securities, other than subordinated liabilities. • Trading derivatives: includes the fair value, with a negative balance for the Bank, of derivatives which do not form part of hedge accounting. • Short positions: includes the amount of financial liabilities arising from the outright sale of financial assets purchased under reverse repurchase agreements or borrowed. • Subordinated liabilities: amount of financing received which, for the purposes of payment priority, ranks behind ordinary debt. This category also includes the financial instruments issued by the Bank which, although equity for legal purposes, do not meet the requirements for classification as equity. • Other financial liabilities: includes the amount of payment obligations having the nature of financial liabilities not included in other items, and liabilities under financial guarantee contracts, unless they have been classified as non-performing. • Hedging derivatives: includes the fair value of the Bank's liability in respect of derivatives, including embedded derivatives separated from hybrid financial instruments, designated as hedging instruments in hedge accounting. • Debt Instruments Eligible to Compose Capital: financial instruments issued by other entities, such as shares, with the nature of equity instruments for the issuer, except investments in subsidiaries, jointly controlled entities or associates.
d) Funding, debt notes issued and other liabilities	d) Funding, debt notes issued and other liabilities Funding debt rates and other liabilities Instruments are recognized initially at fair value, considered primarily as the transaction price. They are measured at amortized cost and its expenses are recognized as a financial cost. Among the liabilities initial recognition methods, it is important to emphasize those compound financial instruments which are classified as such due to the fact that the instruments contain both, a debt instrument (liability) and an embedded equity component (derivative). The recognition of a compound instrument consists of a combination of (i) a main instrument, which is recognized as an entity’s genuine liability (debt) and (ii) an equity component (derivative convertible into ordinary share). The issue of "Notes" must be registered in specific heading liabilities and updated according to the agreed rates and adjusted by the effect of exchange rate variations, when denominated in foreign currency. All remuneration related to these instruments, such as interest and Exchange variation (difference between the functional currency and the currency in which the instrument was named) shall be recognized as expenses for the period, according to the accrual basis. The relevant details of these issued instruments are described in note 19.
e) Measurement of financial assets and liabilities and recognition of fair value changes	e) 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. Financial instruments not measured at fair value through profit or loss, are adjusted by the transaction costs. Financial assets and liabilities are subsequently measured at each period-end as follows: i. Measurement of financial assets Financial assets are measured at fair value, without deduction of estimated costs of transaction that may be incurred on their disposal, except for loans and receivables, held-to-maturity investments, equity instruments whose fair value cannot be determined in a sufficiently objective manner and financial derivatives that have as equity instruments subject and are settled by delivery of those instruments. 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, transparent and deep 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 valuation techniques commonly used by market participants, according to the specific features of the instrument to be measured and, particularly, the various types of risk associated with it. All derivatives are recognized in the balance sheets at fair value from the trade date. If the fair value is positive, they are recognized as assets and if the fair value is negative, they are recognized as liabilities. The changes in the fair value of derivatives from the trade date are recognized in “Gains (losses) on financial assets and liabilities” in the consolidated income statement. Specifically, the fair value of standard financial derivatives included in the portfolios of financial assets or liabilities held for trading is deemed to be their daily quoted price and 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” derivatives. The fair value of OTC derivatives is taken to be the sum of the future cash flows arising from the instrument, discounted to present value at the date of measurement (“present value” or “theoretical close”) using valuation techniques commonly used by market participants: “net present value” (NPV), option pricing models and other methods. “Financial Assets Measured At Amortized Cost” and “Held-to-maturity investments” are measured at amortized cost using the effective interest method. “Amortized cost” is the acquisition cost of a financial asset or liability plus or minus, as appropriate, the principal repayments and the cumulative amortization (taken to the income statement) between the difference of the initial cost and the maturity amount. In the case of financial assets, amortized cost furthermore includes any reductions for impairment or uncollectibility. In the case of loans and receivables hedged in fair value hedges, the changes in the fair value of these assets related to the risk or risks being hedged are recognized. The “effective interest rate” is the discount rate that exactly matches the initial amount of a financial instrument to all its estimated cash flows of all kinds over its remaining life. For fixed rate financial instruments, the effective interest rate coincides with the contractual interest rate established on the acquisition date plus, where applicable, the fees and transaction costs that, because of their nature, form part of their financial return. In the case of floating rate financial instruments, the effective interest rate coincides with the rate of return prevailing in all connections until the next benchmark interest reset date. Equity instruments whose fair value cannot be determined in a sufficiently objective manner are measured at acquisition cost adjusted, where appropriate, by any related impairment loss. Equity instruments whose fair value cannot be calculated in a sufficiently objective manner are measured at acquisition cost, adjusted, as the case may be, to the related impairment losses. The amounts at which the financial assets are recognized represent, in all material respects, the Bank’s maximum exposure to credit risk at each reporting date. Also, the Bank has received collateral and other credit enhancements to mitigate its exposure to credit risk, which consist mainly of mortgage guarantees, cash collateral, equity instruments and personal security, assets leased out under leasing and renting agreements, assets acquired under repurchase agreements and securities loans and derivatives. ii. Measurement of financial liabilities In general, financial liabilities are measured at amortized cost, as defined above, except for those included under “Financial Assets Measured At Fair Value Through Profit Or Loss” and financial liabilities designated as hedge items (or hedging instruments) in fair value hedges, which are measured at fair value. iii. Recognition of fair value changes As a general rule, changes in the carrying amount of financial assets and liabilities are recognized in the consolidated income statement, distinguishing between those arising from the accrual of interest and similar items -which are recognized under “Interest and similar income” or “Interest expense and similar charges”, as appropriate - and those arising for other reasons, which are recognized at their net amount in the heading “Gains (losses) on financial assets and liabilities (net)”. Adjustments due to changes in fair value arising from Available-for-sale financial assets are recognized temporarily in equity in then heading “Other Comprehensive Income”. Items charged or credited to this account remain in the Bank’s consolidated equity until the related assets are written-off, whereupon they are charged to the consolidated income statement. iv. Hedging transactions The consolidated entities use financial derivatives for the following purposes: i) to provide these instruments to clients who request them in the management of their market and credit risks; ii) to use these derivatives in the management of the risks of the Bank entities' own positions and assets and liabilities (“hedging derivatives”); and iii) to obtain gains from changes in the prices of these derivatives (“financial derivatives”). Financial derivatives that do not qualify for hedge accounting are treated for accounting purposes as trading derivatives. A derivative qualifies for hedge accounting if all the following conditions are met: 1. The derivative hedges one of the following three types of exposure: a. Changes in the fair value of assets and liabilities due to fluctuations, among other, in the interest rate and/or exchange rate to which the position or balance to be hedged is subject (“fair value hedge”); b. Changes in the estimated cash flows arising from financial assets and liabilities, commitments and highly probable forecast transactions (“cash flow hedge”); c. The net investment in a foreign operation (hedge of a net investment in a foreign operation). 2. It is effective in offsetting exposure inherent in the hedged item or position throughout the expected term of the hedge, which means that: a. At the date of arrangement the hedge is expected, under normal conditions, to be highly effective (prospective effectiveness). b. There is sufficient evidence that the hedge was actually effective during the whole life of the hedged item or position (retrospective effectiveness). 3. There must be adequate documentation evidencing the specific designation of the financial derivative to hedge certain balances or transactions and how this effective hedge was expected to be achieved and measured, provided that this is consistent with the Bank’s management of own risks. The changes in value of financial instruments qualifying for hedge accounting are recognized as follows: a. In fair value hedges, the gains or losses arising on both the hedging instruments and the hedged items (attributable to the type of risk being hedged) are recognized directly in the consolidated income statement. b. In cash flow hedges, the effective portion of the change in value of the hedging instrument is recognized temporarily in equity under “Other comprehensive Income - Cash flow hedges” until the forecast transactions occur, when it is recognized in the consolidated income statement, unless, if the forecast transactions result in the recognition of non-financial assets or liabilities, it is included in the cost of the non-financial asset or liability. The ineffective portion of the change in value of hedging derivatives is recognized directly in the consolidated income statement. c. The ineffective portion of the gains and losses on the hedging instruments of cash flow hedges and hedges of a net investment in a foreign operation are recognized directly under “Gains (losses) on financial assets and liabilities (net)” in the consolidated income statement. If a derivative designated as a hedge instrument no longer meets the requirements described above due to expiration, ineffectiveness or for any other reason, the derivative is classified as a derivative measured at fair value through profit or loss. When fair value hedge accounting is discontinued (expired, sold our no longer meet hedge accounting criteria) the adjustments previously recognized on the hedged item are transferred to profit or loss at the effective interest rate re-calculated at the date of hedge discontinuation. The adjustments must be fully amortized at maturity. When cash flow hedges are discontinued, any cumulative gain or loss on the hedging instrument recognized in equity in the heading "Other comprehensive Income” (from the period when the hedge was effective) remains recognized in equity until the forecast transaction occurs at which time it is recognized in profit or loss, unless the transaction is no longer expected to occur, in which case any cumulative gain or loss is recognized immediately in profit or loss. For the accounting and disclosure of the hedge accounting structures as of December 31, 2019, the bank used the faculty of IFRS 9, to maintain the practices determined by IAS 39.
f) Settlement of financial assets and liabilities	f) Settlement of financial assets and liabilities Derecognition of Financial Assets The Bank derecognizes a financial asset when the contractual rights to the cash flows of the asset expire or when it transfers the rights to the receipt of the contractual cash flows in a transaction in which essentially all the risks and benefits of ownership of the financial asset are transferred or in which the Bank does not transfer or retain substantially all the risks and rewards of ownership of the financial asset and does not control the financial asset. The difference between the carrying amount of the asset (or book value allocated to the portion of the asset disposed) and the sum (i) of the consideration received (including any new assets obtained, less any new liabilities assumed) and (ii) any accumulated gains or losses recognized in "Other Comprehensive Income" is recorded in the income statement. As from the date of the adoption of IFRS, mentioned above, any accumulated gains / losses recognized in "Other Comprehensive Income" in relation to equity instruments designated at fair value through Other Comprehensive Income are not recorded in the statement of income through the write-off of these securities. The Bank carries out transactions in which it transfers the assets recognized in its balance sheet, but maintains all or substantially all the risks and benefits of the assets transferred or part thereof. In these cases, the transferred assets are not written off. Examples of such operations include assignments of co-sponsored loan portfolios. In operations in which the Bank does not retain or transfer substantially all the risks and rewards of ownership of a financial asset and hold control of the asset, the Bank continues to recognize the asset in the extent of its continued involvement, determined by the extent to which it is exposed to changes in the value of the transferred asset. Derecognition of Financial Assets due to Credit Assignment 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, for an amount equal to the consideration received; this liability 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. 3. If the Bank neither transfers or 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, it continues to recognize the transferred financial asset 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. Derecognition of Financial Liabilities The Bank derecognizes a financial liability when its contractual obligations are terminated, canceled or when they expire.
g) Offsetting of financial instruments	g) Offsetting of financial instruments Financial asset and liability balances are offset (i.e. reported in the consolidated balance sheets at their net amount) only if the Bank and their subsidiaries 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. Offsetting Agreements and Obligations Settlement (CMN Resolution 3.263/2005) - The Bank has an agreement for the clearing and settlement of obligations under the National Financial System (SFN), signed with individuals and legal entities, whether or not members of the SFN, resulting in higher financial settlement guarantee, with the parties that have this modality of agreement. These agreements establish that payment obligations to Banco Santander arising from credit and derivative operations, in the event of default by the counterparty, will be offset against Banco Santander's payment obligations with the counterparty. The following table provides details of financial assets and liabilities subject to offsetting at December 31, 2020, 2019 and 2018: Thousand of reais 2020 Financial assets, gross Financial assets Financial assets Assets: Derivatives 29,431,287 (560,666) 28,870,621 Financial liabilities, gross Financial liabilities Financial liabilities Liabilities: Derivatives 32,540,604 (560,666) 31,979,938 Thousand of reais 2019 Financial assets, gross Financial assets Financial assets Assets: Derivatives 20,904,663 (458,929) 20,445,734 Financial liabilities, gross Financial liabilities Financial liabilities Liabilities: Derivatives 22,888,906 (458,929) 22,429,977 Thousand of reais 2018 Financial assets, gross Financial assets Financial assets Assets: Derivatives 18,667,611 (304,165) 18,363,446 Financial liabilities, gross Financial liabilities Financial liabilities Liabilities: Derivatives 18,771,000 (304,165) 18,466,835
h) Regular way of financial assets purchases	h) Impairment of financial assets i. Definition A financial asset is considered impaired when there is objective evidence that events have occurred which: • Give rise to an adverse impact on the future cash flows that were estimated at the transaction date, in the case of debt instruments (loans and debt securities); • In the case of equity instruments, mean that their carrying amount may not be fully recovered. • Arising from the violation of terms of loans, and • During the Bankruptcy process. As a general rule, the adjustment of the value of the impaired financial instruments is recognized in the consolidated income statement for the period in which the impairment becomes evident, and the reversal, if any, of previously recognized impairment loss is recognized in the consolidated income statement for the period in which the impairment is reversed or reduced. ii. Debt instruments carried at amortized cost The amount of an impairment loss incurred for determination of the recoverable amount on a debt instrument measured at amortized cost is equal to the difference between its carrying amount and the present value of its estimated future cash flows (excluding future credit losses that have not been incurred) discounted the original effective interest rate of the financial asset (or the effective interest rate computed at initial recognition), and is presented as a reduction of the asset balance and recorded in income statements. In estimating the future cash flows of debt instruments the following factors are considered: • All the amounts that are expected to be obtained over the remaining life of the instrument, in this case, the provided guarantees. The impairment loss considers the likelihood of collecting accrued interest receivable. • The various types of risk to which each instrument is subject; and • The circumstances in which collections will foreseeably be made. These cash flows are discounted using the instrument's effective interest rate. Specifically, in regards to recoverable amount losses resulting from materialization of the insolvency risk of the obligors (credit risk), a debt instrument is impaired due to insolvency when there is evidence of a deterioration of the obligor's ability to pay, either because it is in arrears or for other reasons. The Bank has certain policies, methods and procedures for covering its credit risk arising from insolvency allocable to counterparties. These policies, methods and procedures are applied in the granting, in the examination and to document debt instruments, and contingent liabilities and commitments, the identification of their recoverable amount and the calculation of the amounts necessary to cover the related credit risk. The procedures applied in the identification, measurement, control and reduction of the exposure to credit risk, are based on an individual basis or grouped by similarity. • Clients with individual management: Wholesale clients, financial institutions and certain companies. Risk management is performed through an analysis complemented by tools to support the decision-making based in internal risk assessment. • Clients with standardized management: individuals and companies not classified as individual clients. Risk management models based on automated decision-making and risk assessment procedure, complemented, when the model is not comprehensive or accurate enough, by teams of analysts specialized in this type of risk. The credits related to clients standardized, are usually considered not recoverable when they have historical loss experience and delinquency greater than 90 days. Regarding the provision for impairment losses from credit risk, the Bank evaluates all loans. Loans are either individually or collectively evaluated for impairment. Loans accounted as amortized cost, which are not individually evaluated for impairment, are collectively evaluated for impairment, grouping them considering the similarity of risk. Loans individually evaluated for impairment are not included in balances that are collectively evaluated for impairment. To measure the impairment loss on loans individually evaluated for impairment, the Bank considers the conditions of the borrower, such as his economic and financial situation, level of indebtedness, ability to generate income, cash flow , management, corporate governance and quality of internal controls, payment history, industry expertise, contingencies and credit limits, as well as characteristics of assets, such as their nature and purpose, type, sufficiency and liquidity level guarantees and total amount of credit, as well as based on historical experience of impairment and other circumstances known at the moment of evaluation. To measure the impairment loss on loans collectively evaluated for impairment, the Bank segregates financial assets into groups considering the characteristics and similarity of credit risk, in other words, according to segment, the type of assets, guarantees and other factors associated as the historical experience of impairment and other circumstances known at the time of assessment. In some cases, the observable data required to estimate the amount of an impairment loss on a financial asset may be limited or no longer fully relevant to current circumstances. In such cases, an entity uses its experienced judgment to estimate the amount of any impairment loss. Similarly, an entity uses its experienced judgment to adjust observable data for a group of financial assets to reflect current circumstances. The impairment loss is calculated by using statistical models that consider the following factors: Exposure at default (EAD) is the amount of risk exposure at the date of default by the counterparty. The timing of default is considered in the PD measurement. In accordance with IFRSs, the exposure at default used for this calculation is the current exposure, as reported in the balance sheets. • Probability of default, or “PD”, is the probability of the borrower failing to meet its principal and/or interest payment obligations. PD is measured using a time horizon of one year when the transaction is at stage one or for the life time of the transaction, when the it is at stages 2 or 3; that is, it quantifies the probability of the borrower default. A loan will be defaulted if either the principal or interest become past due by ninety days or more or the loan is active but there are doubts about the solvency of the counterparty (subjective doubtful assets). • Loss is given default, or “LGD”, is the loss arising in the event of default. LGD calculation is based on the net charge offs on defaulted loans, considering the guarantees/collateral associated with the loans, the income and expenses associated with the recovery process and the timing of default. • In addition, prior to loans be written-off (which is only done after the Bank have completed all recovery efforts and after about 360 days late), it is registered fully provision of the loan´s remaining balance so this provision (allowance for loan losses) fully covers the losses. Thus, the Bank that its loan loss allowance methodology has been developed to meet its risk metrics and capture loans that could potentially become impaired. iii. Debt or equity instruments classified as financial assets measured at fair value through other comprehensive income The difference between the amortized cost and fair value of debt or equity instruments classified as available for sale are recorded in equity under "Other Comprehensive Income." When there is objective evidence that the aforementioned differences are due to a prolonged decline in fair value, they are no longer recognized in equity and are reclassified, at the cumulative amount at that date, to the consolidated income statement. Losses from a prolonged decline in fair value relating to an investment in equity instruments are not reversed in subsequent periods.
i) Impairment of financial assets	i) Repurchase agreements Purchases (sales) of financial instruments under a non-optional resale (repurchase) agreement at a fixed price (repos) are recognized in the consolidated financial statements as financing granted (received), based on the nature of the debtor (creditor), under Loans and advances with Bacen, Loans and advances to credit institutions or Loans and advances to clients (Deposits from Bacen, Deposits from credit institutions or Client deposits). Differences between the purchase and sale prices are recognized as interest over the duration of the contract.
j) Repurchase agreements	j) Accounting for leases i. Financial leases Financial leases, until December 31, 2018, are leases that transfer substantially all the risks and rewards incidental to ownership of the leased asset to the lessee. From January 1, 2019, see note 1.c.1. When the consolidated entities act as the lessors of an asset, the sum of the present value of the lease payments receivable from the lessee, including the exercise price of the lessee’s purchase option at the end of the lease term when such exercise price is sufficiently below fair value at the option date such that it is reasonably certain that the option will be exercised, is recognized as lending to third parties and is therefore included under Financial Assets Measured At Amortized Cost in the consolidated financial statements. The finance income arising from these contracts is credited in the heading “Interest and similar income” in the consolidated income statement in order to achieve a constant rate of return over the deadline of the lease.
k) Accounting for leases	k) Accounting for Leases - IFRS 16 As of January 1, 2019, the Bank adopted IFRS 16, which replaces IAS 17. I. Transition As permitted by the specific transition provisions, Banco Santander has chosen to apply the rules in a modified retrospective manner, the effects of which were applied on January 1, 2019. The changes in accounting practices resulting from the adoption of IFRS 16 have been applied to assets under right of use as part of tangible assets and lease liabilities as other liabilities in the balance sheet. II. Lease Identification In adopting IFRS 16, the Bank recognized lease liabilities involving leases that had already been classified as “commercial leases” in accordance with the principles of IAS 17 - Leases. For the initial application of the standard, the Bank used the following practical procedures allowed: • The exclusion of initial direct costs for measuring the right-of-use asset on the initial application date; • It was decided not to separate the service provision component embedded in leasing contracts; and • The Bank also decided not to apply IFRS 16 to contracts that were not identified as containing a lease under IAS 17 and IFRIC 4 - Determination of whether a Contract contains a Lease. Additionally, the following recognition exemptions are also being used: • Accounting for operating leases with a remaining term of less than 12 months on January 1, 2019 as short-term leases; • Accounting for operating leases whose underlying asset is of low value; • Until January 1, 2019, leases of fixed assets, in which the Bank, as a lessee, held substantially all the risks and benefits of ownership were classified as finance leases. The balances presented are immaterial. The Bank leases various properties and equipment. Predominantly, the assets subject to the lease agreements are real estate deals referring to the agencies. Banco Santander does not have any rights of use assets that fall within the definition of investment properties. III. Lease term The lease agreements are formalized, analyzed and renegotiated individually and contain a wide range of different terms and conditions. The Bank assesses the term of the contract, as well as the intention to remain in the properties. Thus, the term estimates may vary according to the contractual conditions, considering extension options, and also according to legal provisions. The Bank assumes that fines for contract termination collected before the due date do not make up a significant portion. The lease agreements do not contain restrictive clauses, but the leased assets cannot be used as collateral for loans. IV. Initial Measurement In their initial registration, leases are recognized as a right-of-use asset and a corresponding liability on the date that the leased asset becomes available for use by the Group. The use right to be registered is measured at cost against the lease liability, which represents the present value of lease payments that have not been made to date. The lease payments are discounted using the incremental interest rate on the lessee's loan. There is no onerous contract that required an adjustment to the usage rights to be recorded as assets on the date of initial adoption. Usage rights are measured at amortized cost in accordance with the following: • The value of the initial measurement of the leasing liability; • Any lease payments made before or on the reduced start date of any incentive received; • Any initial cost directly allocated; and • Restoration costs, if the requirements of IAS 37 are met for the recording of Provisions, Contingent Liabilities and Contingent Assets. Grupo Santander uses as an incremental rate the interest rate that it would have to pay when borrowing the necessary resource to obtain the asset with a value similar to the asset under the lease, for term, guarantee and similar economic scenarios, represented in Santander Brasil, by the curve of funding cost (funding) of a free asset, applied individually to each contract according to the projected estimates for the lease term. Lease liabilities include the net present value of the following lease payments: • Reduced fixed payments for any incentive; • Variable payments that are based on a rate or index; • Amounts expected to be paid by the lessee based on the residual value of guarantees; • The exercise price of a call option, if the lessee is reasonably certain about the exercise of the option; and • Penalty payments for terminating the lease if the term of the transaction reflects the exercise of the option by the lessee. Below is presented the projected inflation (IGP-M) on December 31, 2020: Projected IGP-M (annualized) Up to 3 months 26.1% From 3 to 12 months 5.3% From to 1 to 3 years 4% From 3 to 5 years 4% More than 5 years 4% V. Subsequent measurement After the initial measurement, the values ​​of the assets recorded as rights of use are being updated using the cost method, so any accumulated depreciation is deducted monthly, in accordance with the criteria of IAS 16/ CPC 27 - Property, Plant and Equipment in the depreciation of the right of use asset. use and corrected any remeasurement of the lease liability, when applicable. The lease liability initially recorded is updated by monthly increasing the liability amount of the interest installment of each lease and reducing the amount of monthly lease payments and adjusted for any lease remeasurements, when applicable. The lease liability is remeasured, in the event of changes in the lease term or the contract value, the amount resulting from the new determination of the lease liability is recorded against the corresponding asset in use right. The rights of use are subject of impairment test. The effects of adopting IFRS 16 have an impact exclusively on the operating segment - Banco Comercial.
l) Non-current assets held for sale	l) Non-current assets held for sale “Impairment losses” includes the carrying amount of individual items or disposal groups or items forming part of a business unit earmarked for disposal (“Discontinued operations”), whose sale in their present condition is highly probable and is expected to occur within one year, the property or other non-current assets received by the consolidated entities as total or partial settlement of their debtors' payment obligations to them are deemed to be non-current assets held for sale through the completion of actions which normally occurs up to one year. 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. These assets held for sale are not depreciated. 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 in the heading “Gains (losses) on disposal and expenses of non-current assets held for sale not classified as discontinued operations” 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.
m) Residual maturity periods and average interest rates	m) Residual maturity periods and average interest rates The analysis of the maturities of the balances of certain items in the consolidated financial statements at December 31, 2020, 2019 and 2018
n) Tangible assets	n) Tangible assets “Tangible assets” includes the amount of buildings, land, furniture, vehicles, computer hardware, right-of-use of assets and other fixtures owned by the Bank, including tangible assets received by the Bank in full or partial satisfaction of financial assets representing receivables from third parties which are intended to be held for continuing use and tangible assets acquired under finance leases are presented at acquisition cost, less the related accumulated depreciation and any impairment losses (net carrying amount higher than recoverable amount). Depreciation is calculated, using the straight-line method, on the basis of the acquisition cost of the assets less their residual value. The land on which the buildings and other structures are located has an indefinite life and, therefore, it is not depreciated. The tangible asset depreciation charge is recognized in the consolidated income statement and is calculated basically using the following depreciation rates (based on the average years of estimated useful life of the various assets): Annual Buildings for own use 4% Furniture 10% Fixtures 10% Office and IT equipment 20% Leasehold improvements 10% or up to contractual maturity The Bank assesses at end of each reporting period, if there is indication that the items of tangible assets carrying amount may be impaired, that is if there is an asset with its carrying amount bigger than its recoverable amount, either for use or sale. Once an impairment loss of tangible assets is identified, it is adjusted to reach its recoverable amount by recognizing an impairment loss recorded in the heading "Impairment loss on other assets (Net)". Additionally the value of depreciation of that asset is recalculated in order to adjust the value of the life of the asset. In case of evidence or indication of a recovery of a tangible asset value, the Bank recognizes the reversal of the impairment loss amount recorded in prior years and should adjust the future depreciation expenses according to the lifetime value of the asset. Under no circumstance, a reversal of impairment loss of an asset will increase its carrying amount higher than the amount that it would have had no impairment loss been recognized in prior years. Upkeep and maintenance expenses relating to property, plant and equipment for own use are recognized as an expense in the period in which they are incurred.
o) Intangible assets	o) Intangible assets Intangible assets are identifiable non-monetary assets (separable from other assets) without physical substance which arise as a result of a legal transaction or software development. Only assets whose cost can be estimated reliably and from which the consolidated entities consider it probable that future economic benefits will be generated are recognized. Intangible assets are recognized initially at acquisition or production cost and are measured deducting any accumulated amortization and any accumulated impairment losses. i. Goodwill In the acquisition and/or merger of investment in subsidiary, any difference between the investment cost and the investor's share in net fair value of assets, liabilities and contingent liabilities of the investee (subsidiary or affiliate) is accounted for in accordance with IFRS 3 "Business Combination ". Goodwill is only recognized when it has been acquired for consideration and represents, therefore, a payment made by the acquirer in anticipation of future economic benefits from assets of the acquired entity that are not capable of being individually identified and separately recognized. On an annual basis 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 Impairment on non financial assets (net) - Intangible assets in the consolidated income statement. The net fair value adjustments of assets, liabilities and contingent liabilities of the investee in relation to their carrying amount are allocated to individual identifiable assets acquired and liabilities assumed that comprise them based on their respective fair values ​​at the date of purchase. In the case of a business combination made in stages, prior interest in the acquired is measured again at fair value at the acquisition date when control of the acquired is obtained. ii. Other intangible assets Other intangible assets are non-monetary assets without physical substance. Generally arising from software development and acquisition of rights that can generate benefits for the Bank. They can have characteristics of definite or indefinite period. 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 consolidated entities- or a finite useful life, in all other cases. Intangible assets with indefinite useful lives are not amortized. At the end of each accounting period the entity review the intangible asset classification as with indefinite useful live, in case this classification is maintained these assets are subject to annual impairment test (IAS36). Intangible assets with finite useful lives are amortized over those useful lives using methods similar to those used to depreciate tangible assets. The amortization expense is recognized under "Depreciation and amortization" in the consolidated income statement. The Bank assesses at the end of each period, if there is any indication that the items of intangible assets may present an impairment loss, i.e. an asset that presents the carrying amount higher than the net realizable value. After identifying any reduction in impairment loss, it is adjusted to reach its fair value. Measurement of the recoverable amount of other intangible assets - software is made based on the value in use, as well as the analysis of the discontinuity of the asset in relation to the activities of the Bank. Expenditures for acquisition and development of software are amortized over a maximum period of 5 years.
p) Other assets	p) Other assets Other Assets include the balances of all prepayments and accrued income (excluding accrued interest), acquired client list, the net amount of the difference between pension plan obligations and the fair value of the plan assets with a balance on the entity’s behalf, when this net amount shall be disclosed in the consolidated financial statements, and the amount of any other assets not included in other items. The Bank uses the value in use of client relationship as a basis for measuring the impairment since it is not reasonably possible to determine the net value of sales, because there is no basis for making a reliable estimate of the value to be obtained by selling the asset in a transaction at cumulative basis, between knowledgeable, willing parties. The value in use of client lists acquired related to the purchase of the "payroll" will be determined individually. An analysis that aims to demonstrate the expectation of generating future economic benefit and the present value of expected cash flows is prepared by the business areas. Quarterly, these analyses are reviewed based on the actual cash flows of each business (value in use), which are compared with the carrying amount, checking whether there is a need to record a loss on non-recoverability.
q) Liabilities for insurance contracts	q) Liabilities for insurance contracts The liabilities for insurance contracts are comprised substantially by actuarial provisions for current and future benefits (PMBaC and PMBC). Insurance contracts are contracts under which the Bank accepts a significant risk, other than a financial risk, from a policyholder by agreeing to compensate the beneficiary on the occurrence of an uncertain future event by which the policyholder will be adversely affected. Insurance liabilities are recognized when the contract is entered into and the premiums are charged. Contracts that have been classified as insurance are not reclassified. The liability is derecognized when the contract expires or is cancelled. All valuation methods used by the subsidiaries are based on the general principle that the carrying amount of the net liability must be sufficient to meet any reasonably foreseeable obligation resulting from the insurance contracts. Investment assumptions are either determined by the local regulator and based on management’s future expectations. In the later case, the anticipated future investment yield is set by management, considering the available market information and economic indicators. A significant assumption related to estimated gross profits on variable annuities, is the annual long-term growth rate of the underlying assets. At each financial statement date an assessment is made in order to verify whether the actuarial provisions are adequate. In the years ended December 31, 2020, 2019 and 2018 At December 31, 2020, the LAT indicated the need for the additional constitution of technical provisions amounted to R$285,554 (12/31/2019 - R$357,539 and 12/31/2018 - R$215,754) for Indemnity Funds for Benefit (FGB) plans.
r) Provisions for legal and administrative proceedings, commitments and other provisions	r) Provisions for legal and administrative proceedings, commitments and other provisions Banco Santander and its subsidiaries are involved in lawsuits and administrative proceedings related to tax, labor and civil, in the normal course of their activities. The provisions include legal obligations, lawsuits and administrative proceedings related to tax and social security obligations, whose object is to challenge their legality or constitutionality, regardless of the assessment that the probability of success, the amounts are fully recognized in the financial statements. Provisions are reviewed at each financial statement date and adjusted to reflect the current best estimate and may be fully or partially reversed or reduced when the outflows of resources and obligations relevant to the process are no longer probable, including decay of legal deadlines, among others. Provisions for the lawsuits and administrative proceedings are recorded when their risk of loss is considered probable and the amounts can be reliably measured, based on the nature, complexity and history of lawsuits, the legal opinion of the internal and external advisors, based on the best available information. For those lawsuits for which the risk of loss is possible, are not recorded and the information is disclosed in the financial statements and for the lawsuits for which the risk of loss is remote, no disclosure is required. Contingent assets are not recognized, except when there are guarantees or favorable lawsuits decisions, about which features no longer fit, characterizing the gain as practically certain. Assets with probable success, if any, are only disclosed in the financial statements. On the favorable decisions to Santander, the counterparty has the right, in the event of specific legal requirements, to file a rescission lawsuit within a period determined by current legislation. Rescission lawsuits are considered as new events and will be evaluated for contingent liability purposes if and when they are filed.
s) Other liabilities	s) Other liabilities “Other liabilities” includes the balance of all accrued expenses and deferred income, excluding accrued interest, and the amount of any other liabilities not included in other categories.
t) Share-based compensation	t) Share-based compensation The Bank has long-term compensation plans with vesting conditions. The main vesting conditions are: (1) service conditions, since it is necessary that the participant continues to be employed by the Bank during the term of the Plan for his rights to vest; (2) performance conditions, since the number of Units that ultimately vest will be determined according to the result of certain performance parameter of the Bank, such as: total Shareholder Return (TSR) and may be reduced in case of failure to achieve the goals of reducing the Return on Risk Adjusted Capital (RORAC), comparison between actual and budget in each year, as determined by the Board of Directors and (3) market conditions, since some parameters are linked to the market price of the Bank´s shares. The Bank measures the fair value of the services rendered by reference to the fair value of the equity instruments granted at the grant date, considering the market conditions for each plan when estimating the fair value.
u) Recognition of income and expenses	u) Recognition of income and expenses The most significant criteria used by the Bank to recognize its income and expenses are summarized as follows: i. Interest income, interest expenses and similar items Interest income, interest expenses and similar items are generally recognized on an accrual basis using the effective interest method. ii. Commissions, fees and similar items Fees and commission income and expenses are recognized in the income statement using criteria that vary according to their nature (note 34). The main criteria are as follows: • Fee and commission income and expenses relating to financial assets and financial liabilities measured at fair value through profit or loss are recognized when paid; • Those arising from transactions or services that are performed over a period of time are recognized over the life of these transactions or services; and • Those relating to services provided in a single act are recognized when the single act has been performed. iv. Deferred collections and payments These are recognized for accounting purposes at the amount resulting from discounting the expected cash flows at market rates. v. Loan arrangement fees Loan arrangement fees, mainly loan origination and application fees, are accrued and recognized in the income statement over the term of the loan. In the case of loan origination fees, the portion relating to the associated direct costs incurred in the loan arrangement is recognized immediately in the consolidated income statement.
v) Guarantees	v) Guarantees v.1) Financial guarantees “Financial guarantees” are defined as contracts whereby an entity undertakes to make specific payments for a third party if the latter does not do so, irrespective of the various legal forms they may have, such as guarantees, irrevocable documentary credits issued or confirmed by the entity, among others. The Bank initially recognizes the commission of the financial guarantees as liability in the consolidated financial statements at fair value, which is generally the present value of the fees, commissions and similar interest receivable from these contracts over their term. Financial guarantees, regardless of the guarantor, type of instrument or other circumstances, are reviewed periodically so as 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 debt instruments measured at amortized cost. The provisions made for these transactions are recognized in the heading “Provisions - Provisions for contingent liabilities, commitments and other provisions” in the consolidated financial statements (note 22). If a specific provision is required for financial guarantees, the related unearned commissions are recognized in the heading “Financial liabilities at amortized cost – Other financial liabilities” in the consolidated financial statements are reclassified to the appropriate provision. v.2) Guarantees and Credit Risk Mitigation Policy Banco Santander controls the credit risk using the collateral in its operations. Each business unit is responsible for credit risk management and formalizes the use of collateral in its lending policies. Banco Santander uses guarantees in order to increase its ability to recover operations subject to credit risk. The guarantees can be fiduciary, real, legal structures with power mitigation and compensation agreements. Annually the bank reviews its guarantees policies to capture changes in the market, in the caracteristics of the assets given as guarantees and the conditions of the assets, these are examples of technical parameters reviewred. Credit limits are continually monitored and changed in client behavior function. Thus, the potential loss values represent a fraction of the amount available.
w) Assets under management and investment and pension funds managed by the Bank	w) Assets under management and investment and pension funds managed by the Bank Assets owned by third parties and managed by the consolidated entities are not presented in the consolidated financial statements. Management fees are included in “Fee and commission income” in the consolidated income statement. Note 43-b contains information on the third-party assets managed by the Bank. The investment funds and pension funds managed by the consolidated entities are not recorded in the consolidated financial statements since the related assets are owned by third parties. The fees and commissions earned in the year for the services rendered by the Bank entities to these funds (asset management and custody services) are recognized in the heading “Fee and commission income” in the consolidated income statement.
x) Post-employment benefits	x) Post-employment benefits Post-employment benefit plans include the commitments of the Bank: (i) addition to the benefits of public pension plan; and (ii) healthcare in case of retirement, permanent disability or death for those employees, and their direct beneficiaries. Defined contribution plans Defined contribution plans is the post-employment benefit plan which the Bank, and its subsidiaries, as the sponsoring entity pays fixed contributions into a pension fund, not having a legal or constructive obligation to pay further contributions if the fund does not hold sufficient assets to pay all benefits relating to services provided in the current and in previous periods. The contributions made are recognized in the heading "Interest Expense and Similar Charges" in the income statement. Defined benefit plans Defined benefit plan is the post-employment benefit plan which is not a defined contribution plan and is shown in Note 21. For this type of plan, the sponsoring entity's obligation is to provide the benefits agreed with the former employees, assuming the potential actuarial risk that benefits will cost more than expected. For defined benefit plan, the amendment of IAS 19 established fundamental changes in the accounting for and disclosure of employee post-employment benefits such as removing the corridor approach in the accounting for the obligation of the plans, as well as changes in the criteria for recognition of conventional interest of plan assets (valuation based on the discount rate actuarial liability). In addition, there is full recognition in liabilities heading of actuarial losses (actuarial deficit) not recognized previously when they occur, which its counterparty is a heading in the stockholders’ equity (Other Comprehensive Income). Main Definitions - The present value of the defined benefit obligation is the present value without any deduction from the plan assets, of expected future payments required to settle the obligation resulting from employee service in the current and past periods. - Deficit or surplus is: (a) the present value of the defined benefit obligation, less (b) the fair value of plan assets. - The sponsoring entity may recognize the plan assets in the financial statements when they meet the following characteristics: (i) the fund assets are sufficient to meet all employee benefit plan or the sponsor obligations; or (ii) the assets are returned to the sponsoring entity in order to reimburse it for employee benefits already paid. - Actuarial gains and losses correspond to changes in the present value of defined benefit obligation resulting from: (a) adjustments by experience (the effects of differences between the actuarial assumptions adopted and what has actually occurred); and (b) effects of changes in actuarial assumptions. - Current service cost is the increase in the present value of the defined benefit obligation resulting from employee service provided in the current period. - The past service cost is the change in present value of defined benefit obligation for employee service provided in prior periods resulting from a change in the plan or reductions in the number of employees covered. Post-employment benefits are recognized in income in the headings "Interest expense and similar Charges" and "Provisions (net)". The defined benefit plans are recorded based on an actuarial study, conducted annually by an external consulting firm, at the end of each year to be effective for the subsequent period.
y) Other long-term employee benefits	y) Other long-term employee benefits “Other long-term employee benefits”, defined as obligations to early retirees considered as those who have ceased to render services at the entity but who, without being legally retired, continue to have economic rights relating to the entity until they acquire the legal status of retiree, long-service bonuses, obligations for death of spouse or disability before retirement that depend on the employee's length of service at the entity and other similar items, are treated for accounting purposes, where applicable, as established above for defined benefit post-employment plans, except that all past service costs and actuarial gains and losses are recognized immediately (note 21).
z) Termination benefits	z) Termination benefits Termination benefits are recognized when there is a detailed formal plan identifying the basic changes to be made, provided that implementation of the plan has begun, its main features have been publicly announced or objective facts concerning its implementation have been disclosed.
aa) Income taxes (IRPJ), Social Contribution (CSLL), Social Integration Program (PIS) and Tax for Social Security Financing (COFINS)	aa) Income taxes (IRPJ), Social Contribution (CSLL), Social Integration Program (PIS) and Tax for Social Security Financing (COFINS) Income tax expense is obtained by adding the Income Tax, Social Contribution, PIS and COFINS. Current Income Tax and Social Contribution result from the application of the respective rates on taxable income, and the PIS and COFINS rates applied on the respective calculation basis provided for in the specific legislation, added also with changes in deferred tax assets and liabilities recognized in the consolidated income statement. The CSLL rate, for banks of any kind, was increased from 15% to 20% effective as of March 1, 2020, pursuant to Article 32 of Constitutional Amendment 103, published on November 13, 2019. Income tax is calculated at the rate of 15% plus a surcharge of 10% levied on the profit, after adjustments determined by tax legislation. The social contribution (CSLL) is calculated at the rate of 20% for financial institutions (15% up to August 2015) and 9% for other companies, levied on the profit, after considering the adjustments determined by tax legislation. The CSLL rate, for banks of any kind, was increased from 15% to 20% effective as of March 1, 2020, pursuant to article 32 of Constitutional Amendment 103, published on November 13, 2019. The expense for corporate income tax is recognized in the consolidated income statement, except when it results from a transaction recognized directly in equity, in which case the tax effect is also recognized in equity. The current 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. Tax assets classified as "Current" are amounts of tax to be recovered within the next twelve months. Tax liabilities includes the amount of all tax liabilities (except provisions for taxes), which are broken down into “current” amount payable in respect of the income tax on the taxable profit for the year and other taxes in the next twelve months. Deferred tax assets and liabilities include temporary differences, which are identified as the amounts expected to be payable or recoverable on differences between the carrying amounts of assets and liabilities and their related tax bases, and tax loss and tax credit carry forwards. These amounts are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled. Deferred tax assets are only recognized as temporary differences to the extent that it is considered probable that the consolidated entities 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 or accounting profit. Other deferred tax assets (tax loss and tax credit carry forwards) are only recognized if it is considered probable that the consolidated entities will have sufficient future taxable profits against which they can be utilized. Due to the change in social contribution tax rate, the group companies made the remeasurement of tax credit assets and deferred liabilities at the rates applicable to the period in which estimates the realization of assets and settlement of liabilities. Income and expenses recognized directly in stockholders equity are accounted as temporary differences. The deferred tax assets and liabilities recognized are reassessed at each financial statement date in order to ascertain whether they still exist, and the appropriate adjustments are made on the basis of the findings of the analyses performed. Under the current regulation, the expected realization of tax credits is based on the Bank's projections of future results and on technical technical analysis of the realization of the temporary differences, as shown in Note 23. PIS (Social Integration Program) and COFINS (Tax for Social Security Financing) have been computed at a combined rate of 4.65% on certain gross revenues and expenses. Financial institutions may deduct financial expenses in determining the PIS/COFINS tax basis. PIS and COFINS are considered a profit-base component (net basis of certain revenues and expenses), therefore and accordingly to IAS 12 it is recorded as income taxes. • IFRIC 23 - Published in June 2017 by the IASB, IFRIC 23 - Uncertainty over Income Tax Treatments on Profit has mandatory application as of January 1, 2019 and aims to clarify procedures for the application of recognition and measurement requirements established in the IAS 12 of Taxes on Profit when there is uncertainty about the treatments to be adopted for the Taxes on Profit. The Bank carried out analyzes on the procedures already adopted for accounting and presentation of Income Taxes in relation to the content of IFRIC 23 and it was possible to conclude that there are no impacts on related measurements nor disclosures.

Sensibilities	The interest rate risk in balance sheets management portfolios, measured in terms of sensitivity of the net interest margin (NIM) at one year to a parallel increase of 100 b.p. in the interest rate curve, was at the beginning of 2019 and 2018, reaching a maximum of R$134 million in December 2019. The sensitivity value decreased R$202 million during 2019, reaching a maximum of R$2,342 million in October. The main factors that occurred in 2019 and influenced in sensitivity were the volatility of the exchange rate (convexity effect), portfolio’s decayment update of implicit methodology on cash flow of the Bank’s products and liquidity.

Risk Type	In calculating the economic capital, it is the Bank's definition of losses to be covered. Thus, it is used a confidence interval necessary to ensure business continuity. The risk profile in Brazil is distributed by Credit risk, Market, ALM, Business, Operations and materials assets. However, to successfully anticipate the changes proposed in Basel III, new risks have been incorporated to model: Intangibles, pension funds (defined benefit) and deferred tax assets, which allow the Bank to adopt a position even more conservative and prudent. % Capital 2020 2019 2018 Risk Type Credit 69% 72% 72% Market 2% 2% 2% ALM 2% 5% 8% Business 3% 3% 6% Operational 6% 7% 5% Fixed Assets 2% 2% 1% Intangible Assets 5% 1% 0% Pension Funds 2% 4% 1% Deferred Tax Assets 9% 5% 5% TOTAL 100% 100% 100%

[1]	In the year ended December 31, 2018 there was an increase in the cost contribution established for a postemployment benefit plan, which is calculated as a percentage of the total monthly compensation of associates, The increase in the contribution resulted in a decrease in the past service cost, due to changes in the plan, The envisaged changes implied a reduction in the present value of the obligations of the defined benefit plan, which is supported by actuarial valuations, In the Consolidated Statements of Income, this amount was recorded under Provision (Net).
