Disclosure of reclassifications or changes in presentation [abstract]
Introduction, basis of presentation of the interim condensed consolidated financial statements and other information	Introduction, basis of presentation of the interim condensed consolidated financial statements and other information a) Introduction Banco Santander, S.A. (“Bank” or “Banco Santander”) is a private-law entity subject to the rules and regulations applicable to banks operating in Spain. The Bylaws and other public information of the Bank can be consulted at its registered office at Paseo de Pereda 9-12, Santander. In addition to the operations carried on directly by it, the Bank is the head of a group of subsidiaries that engage in various business activities and which compose, together with it, Santander Group (“Group” or “Santander Group”). b) Basis of presentation of the interim financial statements Under Regulation (EC) no. 1606/2002 of the European Parliament and of the Council of 19 July 2002, all companies governed by the law of an EU Member State and whose securities are admitted to trading on a regulated market of any Member State must prepare their consolidated annual accounts for the years beginning on or after 1 January 2005 in accordance with the International Financial Reporting Standards (“IFRSs”) as previously adopted by the European Union (“EU-IFRSs”). In order to adapt the accounting system of Spanish credit institutions to these standards, the Bank of Spain issued Circular 4/2004, of 22 December, on Public and Confidential Financial Reporting Rules and Formats, which was repealed on 1 January 2018 by Bank of Spain Circular 4/2017, of 27 November 2017, and subsequent modifications. The consolidated annual accounts for 2019 were approved at the board of directors meeting on 27 February 2020 in compliance with International Financial Reporting Standards as adopted by the European Union, taking into account Bank of Spain Circular 4/2017, and subsequent modifications, using the basis of consolidation, accounting policies and measurement bases described in Note 2 to the aforementioned consolidated annual accounts and, accordingly, they presented fairly the Group’s consolidated equity and consolidated financial position at 31 December 2019 and the consolidated results of its operations, and the consolidated cash flows in 2019. The aforementioned consolidated annual accounts, which are included in the Group’s Form 20-F filed with the U.S. Securities and Exchange Commission on 6 March 2020, and these interim financial statements are also in compliance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS-IASB”, and together with EU-IFRS, “IFRS”). These interim financial statements were prepared and are presented in accordance with International Accounting Standard (IAS 34), Interim Financial Reporting, for the preparation of interim condensed financial statements, in conformity with Article 12 of Royal Decree 1362/2007, and taking into account the requirements of Circular 3/2018, of 28 June, of the Spanish National Securities Market Commission (“CNMV”). The aforementioned interim financial statements were included in the half-year financial report for the first six months of 2020 to be presented by the Group in accordance with the Circular 3/2018. In accordance with IAS 34, the interim financial statements are intended only to provide an update on the content of the latest consolidated annual accounts authorised for issue, focusing on new activities, events and circumstances occurring during the first six months, and does not duplicate information previously reported in the latest consolidated annual accounts. Consequently, these interim financial statements do not include all the information that would be required for a complete set of consolidated annual accounts prepared in accordance with IFRSs and, accordingly, for a proper comprehension of the information included in these interim financial statements, they should be read together with the Group’s consolidated annual accounts for the year ended 31 December 2019. Santander Group policies include presenting the interim financial statements for its use in the different markets using the Euro as its presentation currency. The amounts held in other currencies and the balances of entities whose functional currency is not the Euro, have been translated to the presentation currency in accordance with the criteria indicated in Note 2.a to the consolidated annual accounts for 2019. As indicated in that Note, for practical reasons, the balance sheet amount has been converted to the closing exchange rate, the equity to the historical type, and the income and expenses have been converted by applying the average exchange rate of the period; the application of such exchange rate or that corresponding to the date of each transaction does not lead to significant differences in the interim financial statements of the Group. The accounting policies and methods used in preparing these interim financial statements are the same as those applied in the consolidated annual accounts for 2019, taking into account the standards and interpretations that became applicable during the first six months of 2020, which are detailed below: - Modification of IFRS conceptual framework: The IFRS Framework, which sets out the fundamental concepts of financial reporting, is amended. The revised Framework includes: a new chapter about measurement; guidance on financial reporting; improved definitions, in particular the definition of liabilities; and clarifications such as management functions, prudence and measurement uncertainty in financial reporting. - Modification of IAS 1 Presentation of financial statements and IAS 8 Accounting policies, changes in accounting estimates and errors, which use a consistent definition of materiality, for the purpose of making material judgements and deciding on the information to be included in the financial statements. - Modification of IFRS 3 Business combinations - amendments are introduced. The amendments are intended to assist entities to determine whether a transaction should be accounted for as a business combination or as an asset acquisition. IFRS 3 continues to adopt a market participant’s perspective to determine whether an acquired set of activities and assets is a business. The amendments are mainly due to: clarify the minimum requirements for a business; remove the assessment of whether market participants are capable of replacing any missing elements; add guidance to help entities assess whether an acquired process is substantive; narrow the definitions of a business and of outputs; and introduce an optional fair value concentration test. The aforementioned amendments to accounting standards and interpretations have not had a significant effect on the Group’s financial statements. All accounting policies and measurement bases with a material effect on the interim financial statements for 30 June 2020 were applied in their preparation. By the time of the preparation and authorisation of these interim financial statements, there was the following standard to be adopted by the European Union whose effective date of implementation by the IASB is 1 January 2020. - Modification of IFRS 16 Leases - amendments are introduced. The amendment provides a practical expedient that permits leases not to assess whether rent concessions that occur as a direct consequence of the COVID-19 pandemic and meet specific conditions are lease modifications and, instead, to account for those rent concessions as if they were not lease modifications. The effective date of entry into force of this amendment is 1 June 2020, allowing early implementation. No significant effects on the Group's interim financial statements are expected from the future application of the aforementioned amendments to the accounting standard. c) Use of critical estimates The consolidated results and the determination of the consolidated equity are sensitive to the accounting principles and policies, valuation criteria and estimates used by the directors of the Bank in preparing the interim financial statements. The main accounting principles, policies, and valuation criteria are indicated in Note 2 of the consolidated annual accounts of the year 2019, except for those indicated in these interim financial statements due to the rules that have come into effect during the first six months of the year 2020. The interim financial statements contain estimates made by the senior management of the Bank and of the consolidated entities in order to quantify certain of the assets, liabilities, income, expenses and obligations reported herein. These estimates, which were made on the basis of the best information available, relate mainly to the following: 1. The income tax expense, which, in accordance with IAS 34, is recognised in interim periods based on the best estimate of the weighted average tax rate expected by the Group for the full financial year; 2. The impairment losses on certain assets – Financial assets at fair value through other comprehensive income, financial assets at amortised cost, non-current assets held for sale, investments in subsidiaries, joint ventures and associates, tangible assets and intangible assets; 3. The assumptions used in the calculation of the post-employment benefit liabilities and commitments and other obligations; 4. The useful life of the tangible and intangible assets; 5. The measurement of goodwill impairment arising on consolidation; 6. The calculation of provisions and the consideration of contingent liabilities; 7. The fair value of certain unquoted assets and liabilities; 8. The recoverability of deferred tax assets; and 9. The fair value of the identifiable assets acquired and the liabilities assumed in business combinations in accordance with IFRS3. To update the above estimates, the Group's management has considered that since March 2020, COVID-19, a new strain of Coronavirus, has spread to many countries, including Spain. This event has resulted the viral outbreak to be classified as a pandemic by the World Health Organization, which significantly affects economic activity worldwide and, as a result, the Group's operations and financial results. While there has been a worsening of the macroeconomic outlook to date, the extent to which COVID-19 will ultimately impact the Group's results will depend on future developments, including actions to contain or treat the disease and mitigate its impact on the economies of the affected countries, which generate uncertainties in the Group’s estimates. For this reason, the Group's management has assessed the current situation according to the best information available, then developing the potential impacts of COVID-19 on the estimates made during the first six months ended 30 June 2020. From the results of this evaluation, the following aspects stand out: - Estimation of expected credit losses: Context The COVID-19 health crisis has been unexpected, unpredictable and severe, but it is estimated to be of a limited temporary nature. The Group's priority in these circumstances has been to look after the health of its employees, customers and shareholders, but also to help reduce the economic impact that the coronavirus pandemic may have. This includes trying to offer the best solutions to help individual customers and businesses. Conceptually, the phases in managing the effects of COVID-19 have been: – Identification of customers or groups affected or potentially affected by the pandemic. – Early relief of temporary financial difficulties caused by COVID-19 through measures promoted by governments, central banks, and financial institutions. – Monitoring the evolution of customers, to ensure that they continue to be provided with the best solution for their situation, and also to guarantee that their potential impairment is correctly reflected in the Group's risk management and accounting. – Monitoring is accompanied by recovery management activities when necessary. These conceptual phases do not occur sequentially but overlap in time. Additionally, the continuous interaction and coordination between the different local units of the Group is proving to be a fundamental asset in the management of this crisis. The experience obtained in the fight against the health crisis and its financial consequences in our different geographies, and the different speeds at which it has been developing in each of them, allow us to share the best practices identified and to implement in an agile and efficient manner those strategies and concrete actions that have been most successful, always adapted to the local reality of each market. Measures to support the economy In accordance with the comments made earlier regarding the relief of our clients' temporary financial difficulties caused by the pandemic, the Group has adopted measures to foster the economic resilience of our clients during the crisis in all regions. The most outstanding of these include the following: – Providing liquidity and credit facilities to companies facing difficulties. – Facilitate grace periods or moratoriums in many of their markets. – Temporary option to increase the limit on credit cards and overdrafts. – Support vulnerable customers (elderly, SMEs, etc.) by being proactive and trying to cover their needs. – Temporary reduction or suspension of commissions (when withdrawing money from ATMs, on interest-free online purchases, on bank transfers...). – Guaranteeing COVID-19 coverage in health insurance. – Specialized teams to advise clients in financial difficulties. Regarding specific liquidity measures, shortages or moratoriums, the Group has implemented a series of support programmes in accordance with the guidelines set by regulatory and supervisory authorities, as well as by governments, central banks and supranational entities. The main objective is to mitigate the temporary impact on the activity of our customers, since the absence of appropriate measures and their adequate prudential and accounting treatment could worsen the economic consequences of the crisis, generating procyclical effects that would lengthen its duration and impact. The different measures offered can be grouped into the following categories: – Government liquidity measures: Generally speaking, these are lending facilities provided by the bank to legal entities, which have government guarantees on a specific percentage of the exposure generated in the event of default. Examples of this type of measure include ICO ( Instituto de Crédito Oficial ) loans in Spain or the Paycheck Protection Program (PPP) in the United States. – Government moratorium measures: In this case, the government authorities define a series of requirements, which, in the event that they are met by the beneficiary, involve the granting of moratoriums by the bank on the payment of capital and/or interest on the various credit operations that customers may have contracted. The specific characteristics of these programs vary depending on how they are defined by the national governments of the – Internal/sectoral moratorium measures: This is, broadly speaking, the granting of moratoriums by the bank on the payment of capital and/or interest on the various credit operations that customers may have contracted. In this case, the specific characteristics of these measures, in terms of terms, amounts, etc., vary according to each geography, product or customer segment in order to adapt them as best as possible to the reality of the local market and its regulation, as well as to the needs of the customer and the product contracted. In many cases, the general conditions of application have been agreed on a sectoral basis, for example through the national banking associations. – Other internal measures: This category includes all those measures not included in the previous sections. The Group has helped customers through the various liquidity programmes, government guarantees, moratoriums and others. The details and magnitude of these measures and their main characteristics can be consulted in section "COVID-19 pandemic implications" . Estimation of expected loss In the context described in the previous sections, many regulators and supervisors have highlighted the uncertainties surrounding the economic impacts of the health crisis. This is also evident in the frequent updates of macroeconomic forecasts, with different perspectives and views on the depth and duration of the crisis. Thus, the guidance (including IASB, ESMA, EBA and ECB) does not set a mechanistic approach to estimating expected credit losses under IFRS 9, in order to prevent this variability in economic conditions from translating into undesired volatility in results, with its potential pro-cyclical effects on the economy. Thus, the Group analyses losses under IFRS 9 on the basis of three types of elements: 1. Continuous monitoring of customers Monitoring the credit quality of customers may be more complex in the current circumstances, in the absence of certain contractual payments on transactions subject to a moratorium. To this end, and in addition to the application of internal customer monitoring policies, all available information should be used. The availability of information and its relevance is different in the various portfolios of the different countries in which the Group operates, but it may include, but is not limited to the following: – The payment of interest in the case of principal-only shortfalls. – The payment of other operations of the same client in the institution (not subject to moratorium). – Information on payment of loans in other entities (through credit bureaus). – Customer financial information: average balances in current accounts, availability/use of limits, etc. – Available behavioural elements (variables that feed the behavioural scores, etc.) – Information gathered from customer contacts (surveys, calls, questionnaires, etc.). This may include: customers who have taken up furlough programs, direct government aid, etc. 2. Forward-looking vision As reflected by the IASB, macroeconomic uncertainty makes the usual application of IFRS9 expected loss calculation models difficult but does not exempt the incorporation of the prospective feature of the standard. To this end, the European Central Bank has recommended the use of a stable, long-term view (long-run) of the macroeconomic forecasts, which takes into account in the assessment the multiple support measures explained above. Santander Group uses macroeconomic scenarios in its strategic and budgetary processes. For the purposes of estimating provisions under IFRS9, in accordance with the regulatory recommendations, the long-run view consistent with these scenarios was used. This long-run vision is generated through a stable long-term perspective, reflecting the structural impairment caused by the pandemic. For this propuse, the movement when the macro, represented by the GDP, recovers its average trend is analysed for each geography, taking into account seasonal factors applicable to each economy. 3. Additional elements Additional elements will be required when necessary because they have not been captured under the two previous elements. This includes, among others, the analysis of sectors most affected by the pandemic if their impacts are not sufficiently captured by the macroeconomic scenarios. Also collective analysis techniques, when the potential impairment in a group of clients cannot be identified individually. With the elements indicated above, the Group evaluates in each of the geographical areas the evolution of the credit quality of its customers, for the purposes of their classification in the Group's financial statements. In terms of classification, the Group has generally maintained the criteria and thresholds for classification during the pandemic, incorporating the regulatory interpretations of the effect of moratoria on classification (in particular, the European Banking Authority's 'Guidelines on legislative and non-legislative moratoria on loan repayments applied in COVID-19 crisis'). In this way, moratoriums that meet the specifications of these guidelines are not considered as automatic indicators for identifying these contractual changes as forbearances or classifying them in stage 2. However, this does not exempt the rigorous application of IFRS9 in the monitoring of costumer credit quality and, using individual or collective analysis techniques, the timely detection of significant increases in risk in certain transactions or groups of transactions. Details of the exposure by stage can be found in Note 5 in this interim condensed consolidated financial statement. This note shows the levels of provisions for the first six months, which amount to EUR 7,027 million, including the provisions to cover the impact to date on expected losses resulting from the pandemic. - Liabilities and commitments for post-employment compensation and other obligations: considering the long-term nature of these commitments, the valuation and main hypothesis-setting criteria are maintained for recording and accounting for post-employment and long-term commitments except for Spain, which has updated its estimates with new mortality tables. On the other hand, eligible assets are quantified at market value and the reference discount rate to determine the value of the obligation continues to be the interest rate of corporate bonds with high credit ratings at the accounting reference date consistent with the duration of the obligations, although the high volatility of the spreads corresponding to said bonds in the last days of the first six months has been taken into account. - Useful life of tangible and intangible assets: based on the type of Group's assets, there have been no significant changes in the estimates of useful life made at the end of 2019 due to COVID-19. - Goodwill: The accounting standard (IAS 36) requires that a cash‑generating unit (“CGU”) to which goodwill has been allocated is tested for impairment annually, and whenever there is an indication that the goodwill may be impaired. The Group’s impairment test in respect of goodwill allocated to each CGU is performed annually. Nevertheless, a review for indicators of impairment is undertaken at each quarter-end. Having considered the reasons explained below, an interim impairment test has been performed at 30 June 2020 for all certain CGUs. The standard establishes a minimum of indicators in assessing whether there is any indication, so even though there is still high uncertainty about how the crisis is going to impact the economies of some of our subsidiaries, the Group considers the circumstances described below as indications of impairment: • Current changes in the economic environment where a decrease of the GDP is expected in most countries and its recovery will take 2 or 3 years. The evolution forecasted by the different national and international organisms for 2020 magnitudes such as GDP, unemployment rate, credit portfolios growth, etc. are negative and the recovery of these economies, will be less steep and at a slower pace than its fall. • The uncertainty in the macroeconomic situation also causes higher expected returns, and market premiums increase significantly. As a result of the higher cost of capital, the discount rates applied to the cash flows are higher (rates reflect the risk associated to the current environment), which result in a lower value in use. • Additionally, the Group is already observing budget deviations in some of the subsidiaries due to the current macroeconomic outlook, which also negatively affect the future cash flows. Considering these trigger events, as of 30 June 2020 the Group has performed its impairment test. In relation with goodwill assessment (i.e. a potential reduction in its recoverable value to below its carrying amount), during the first six months of 2020 the Group recognised goodwill impairment losses amounting to EUR 10,100 million under the heading Impairment on non-financial assets, net - Intangible assets of the condensed consolidated income statement (see Note 8.a). - Provisions and contingent liabilities: the Group's management, after its analysis, has concluded that there have been no significant changes in the estimates made at the end of the 2019 fiscal year in relation to the probability of the obligations that the Group has to meet at 30 June 2020 due to the situation produced to date by COVID-19. - Market risk: the pressures observed in the financial markets during the first semester of 2020 did not have a significant impact in terms of valuation, impairment or allocation of levels for the Group's portfolios, considering, the typology of the Group's products, the low complexity of the portfolios, the decrease in volatility and credit spreads in the second quarter and the observability of the price sources used. There is currently no significant reduction in observables price from sources used for the valuation of financial instruments, although there is still some widening of the price ranges and some dispersion among the various contributors. Therefore, it has meant that no significant worsening of the observable conditions has been detected in the inputs used for the valuation of portfolio financial instruments, nor less access to price contributors and real market operations. Consequently, considering the composition of the Group's portfolios, the impact on the fair value hierarchy has been reduced and most markets and terms have maintained their classifications according to our observability and significance criteria. Given the low market complexity as a general rule of our portfolios, and despite certain increases in valuation adjustments to adequately reflect their fair value in a still volatile environment, there have been no significant reclassifications between levels. The Group continues to monitor the evolution of the markets, their liquidity and the observability conditions of the valuation inputs in order to apply the criteria established in the Group for the levelling of assets and liabilities measured at fair value. The risk levels measured in terms of VaR for all Group's units are at historically low levels. During the first quarter of the year, and despite a general reduction in positions in a context of high volatility, there was a certain one-off increase in VaR as a result of the use of the Weighted VaR methodology, which assigns greater weight to the most recent market scenarios. However, the return to normal market conditions in recent months and the maintenance of reduced positions in most trading portfolios has enabled that at the end of the second quarter risk exposure is at historically low levels of approximately EUR 10 million (VaR 1d 99%). - Deferred tax assets: the Group has reassessed the ability to generate future taxable income in relation to the recoverability of deferred tax assets recorded in the main Group companies. Management considers that the recovery period of these assets would not be affected and that it is not necessary to make adjustments to the deferred tax assets recognised in the Group on the basis of the results of the analyses performed, except in Spain, where the Group considers that the changes in the key assumptions on which the projected results of its tax group are based, arising from the impact of COVID-19 according to the circumstances described in the previous section related to goodwill, have resulted in the recognition of an impairment of EUR 2,500 million of deferred tax assets under tax income in the income statement, maintaining a maximum 15 year period of recoverability of the deferred tax assets recognised at 30 June 2020. During the first six months ended 30 June 2020, there have been no additional significant changes in the estimates made at the end of 2019, other than those indicated in this interim financial information. d) Contingent assets and liabilities Note 2.o to the Group's consolidated annual accounts for the year ended 31 December 2019 includes information on the contingent assets and liabilities at that date. There were no significant changes in the Group’s contingent assets and liabilities from 31 December 2019 to the date of formal preparation of these interim financial statements. e) Comparative information Based on the meeting held on 3 March 2020 by the International Financial Reporting Interpretations Committee (IFRIC), the Group changed its accounting policy in relation to the presentation of exchange differences and the effects of hyperinflation of operations generated in Argentina, what has led to a reclassification of EUR -1,984 million at 1 January 2019 from “Other reserves” to “Other comprehensive income”, relating to the accrued amount of exchange rate differences arising from foreign operations in a hyperinflationary economy and the amount relating to the adjustment of the Argentine companies’ carrying costs reflecting the changes in the purchasing power of the currency due to inflation. For the purpose of its comparability, the Group has restated at 30 June 2020 and 31 December 2019, EUR -1,952 million and EUR -2,136 million, respectively. This change on its accounting policy and its consequent restatement between different equity items has no impact on the Group's total equity. In order to interpret the changes in the balances with respect to 31 December 2019, it is necessary to take into consideration the exc hange rate effect arising from the volume of foreign currency balances held by the Group in view of its geographic diversity (Note 51.b to the consolidated annual accounts for the year ended 31 December 2019) and the impact of the appreciation/depreciation of the various currencies against the euro in the first six months of 2020: Mexican peso (-18.26%), US dollar (-0.20%), Brazilian real (-26.70%), Argentine peso (-15.19%), Pound sterling (-6.47%), Chilean peso (-8.38%) and Polish zloty (-4.20%); as well as the evolution of the average exchange rates between comparable periods: Mexican peso (-7.45%), US dollar (2.11%), Brazilian real (-16.29%), Argentine peso (-13.66%), Pound sterling (1.25%), Chilean peso (-12.83%) and Polish zloty (-2.34%). f) Seasonality of the Group’s transactions The business activities carried on by the Group entities, and their transactions are not cyclical or seasonal in nature. Therefore, no specific disclosures are included in these explanatory notes to the interim financial statements for the first six months ended 30 June 2020. g) Materiality In determining the note disclosures to be made on the various items in the interim financial statements or other matters, the Group, in accordance with IAS 34, took into account their materiality in relation to the interim financial statements for the first six months ended 30 June 2020. h) Events after the reporting period From 1 July 2020 until the approval date of the interim financial statements for the first six months ended 30 June 2020, no significant events other than those indicated in the interim financial statements have occurred. i) Other information United Kingdom Referendum 31 January 2020 the United Kingdom ceased to be a member of the European Union . The UK and the European Union agreed withdrawal terms which establish a transition period until 31 December 2020. During the transition period (i) the United Kingdom will be treated as if it were still a member of the European Union for trading purposes, (ii) European Union legislation will continue to apply in the United Kingdom and (iii) negotiations on a trade agreement will be conducted, as well as on the extent of legislative and regulatory convergence and regulatory cooperation. The European Union will also carry out regulatory equivalence assessments for financial services. Such assessments, even if positive, do not guarantee that equivalence will be granted. Although the withdrawal agreement foresees the possibility to extend the transition period for two more years after the 31 January 2020, this is not automatic and the United Kingdom has enshrined the 31 December 2020 date in local legislation passing the withdrawal agreement as the end of the transition period, signalling a current desire not to extend it. Uncertainty remains around the terms of the United Kingdom´s relationship with the European Union at the end of the transition period. If the transition period were to end without a comprehensive trade agreement, the United Kingdom’s and Europe´s economic growth may be negatively impacted. At the end of the transition period, even if a trade agreement is entered into force and/or if equivalence is granted to certain areas of the United Kingdom’s financial services, conti

Santander Group	Santander GroupAppendices I, II and III to the consolidated annual accounts for the year ended 31 December 2019 provide relevant information on the Group companies at that date and on the companies accounted for under the equity method. Also, Note 3 to the aforementioned consolidated annual accounts includes a description of the most significant acquisitions and disposals of companies performed by the Group in 2019, 2018 and 2017. The most significant transactions taking place during the first six months of 2020 or pending at 30 June 2020 are as follows: Agreement for the acquisition of a significant stake in Ebury On 28 April 2020, the investment in Ebury, one of the best payment and currency platforms for SMEs, announced on 4 November 2019, was completed. The transaction involved a total outlay of GBP 367 million (approximately EUR 410 million) of which GBP 70 million (approximately EUR 80 million) was for new shares to support the company's plans to enter new markets in Latin America and Asia. At 2019 year-end the Group had already acquired 6.4% of the company for GBP 40 million (approximately EUR 45 million). Following the disbursement made in April 2020, the Group is entitled to receive 50.38% of the dividends distributed by the company. This interest is recognised under "Investments in Joint Ventures and Associates - Associates" in the consolidated balance sheet. Reorganizatio n of the banking insurance business, asset management and pension plans in Spain On 24 June 2019, Banco Santander, S.A. reached an agreement with the Allianz Group to terminate the agreement that Banco Popular Español, S.A.U. (“Banco Popular”) held in Spain with the Allianz Group for the exclusive distribution of certain life insurance products, non-life insurance products, collective investment institutions, and pension plans through the Banco Popular network (the “Agreement”) whereby the Group held a 40% stake in the capital of Allianz Popular, S.L., classified as investments in joint ventures and associated entities for an overall amount of EUR 409 million on 31 December 2019. The Agreement was executed on 15 January 2020 for the non-life business and on 31 January 2020 for the remaining businesses, once the regulatory authorisations were obtained in the first quarter of 2020. The execution of the Termination Agreement entailed the payment by Banco Santander of a total consideration of EUR 859 million (after deducting the dividends paid until the end of the operation) and the acquisition of the remaining 60% of the capital of Allianz Popular, S.L. On July 10, 51% of the life-risk insurance business held by Banco Santander and 51% of the new General Insurance business from Banco Popular's network not transferred to Mapfre (in accordance with the agreement indicated below) was acquired by Aegon, valuing these businesses at a total of approximately EUR 557 million. The total amount of the life-savings business, collective investment institutions and pension plans is EUR 711 million and has resulted in the recognition of EUR 271 million of goodwill. In addition, under the agreement reached between Banco Santander and Mapfre on 21 January 2019, 50.01% of the car, commercial multi-risk, SME multi-risk and corporate liability insurance business in the whole of Banco Santander's network in Spain was acquired by Mapfre on 25 June 2019 for EUR 82 million.

The Group, even before the ECB’s announcement, had agreed to cancel the interim dividend charged against 2020 and suspend its decision on 2020 dividends until there was more clarity regarding the impact of the crisis. This decision was taken to ensure the Bank has as much flexibility as possible to allow it to maximise lending and support businesses and individuals affected by the COVID-19 pandemic. With the current greater visibility and given the Bank's capital strength and the performance of underlying results, the Board intends to propose to the Shareholders' Meeting the payment of a scrip dividend (payable in new shares) equivalent to EUR 0.10 per share, for a total dividend equivalent to EUR 0.20 charged to 2019 results. In addition, the Bank has accrued 6 basis points of CET1 capital in the quarter to allow the flexibility to pay a cash dividend against 2020 results, as soon as market conditions normalise and subject to regulatory approvals and guidance. b) Earnings per share from continuing and discontinued operations i. Basic earnings per share Basic earnings per share for the period are calculated by dividing the net profit attributable to the Group for the first six months adjusted by the after-tax amount relating to the remuneration of contingently convertible preference shares recognised in equity by the weighted average number of ordinary shares outstanding during the period, excluding the average number of treasury shares held in the period. Accordingly: 30-06-2020 30-06-2019 Profit attributable to the Parent (million euros) (10,798) 3,231 Remuneration of contingently convertible preference shares (million euros) (278) (298) (11,076) 2,933 Of which: Profit or Loss from discontinued operations (non controlling interest net) (million euros) — — Profit or Loss from continuing operations (PPC net) (million euros) (11,076) 2,933 Weighted average number of shares outstanding 16,598,649,355 16,231,374,256 Basic earnings per share (euros) (0.67) 0.18 Of which: from discontinued operations (euros) — — from continuing operations (euros) (0.67) 0.18 ii. Diluted earnings per share Diluted earnings per share for the period are calculated by dividing the net profit attributable to the Group for the first six months adjusted by the after-tax amount relating to the remuneration of contingently convertible preference shares recognised in equity and of perpetual liabilities contingently amortisable in their case by the weighted average number of ordinary shares outstanding during the period, excluding the average number of treasury shares and adjusted for all the dilutive effects inherent to potential ordinary shares (share options, warrants and convertible debt instruments). Accordingly, diluted earnings per share were determined as follows: 30-06-2020 30-06-2019 Profit attributable to the Parent (million euros) (10,798) 3,231 Remuneration of contingently convertible preference shares (million euros) (278) (298) Dilutive effect of changes in profit for the period arising from potential conversion of ordinary shares — — (11,076) 2,933 Of which: Profit or Loss from discontinued operations (non controlling interest net) (million euros) — — Profit or Loss from continuing operations (PPC net) (million euros) (11,076) 2,933 Weighted average number of shares outstanding 16,598,649,355 16,231,374,256 Dilutive effect of options/receipt of shares 40,016,222 41,832,881 Adjusted number of shares 16,638,665,577 16,273,207,137 Diluted earnings per share (euros) (0.67) 0.18 Of which: from discontinued operations (euros) — — from continuing operations (euros) (0.67) 0.18

Intangible assets	Intangible assets a) Goodwill The detail of Intangible Assets - Goodwill at 30 June 2020 and 31 December 2019, based on the cash-generating units giving rise thereto, is as follows: Million euros 30-06-2020 31-12-2019 Banco Santander (Brasil) 3,216 4,388 SAM Investment Holdings Limited (*) 1,444 1,173 Santander Consumer Germany 1,236 1,236 Santander Bank Polska 1,133 2,427 Santander Portugal 1,040 1,040 Santander España 1,027 1,027 Santander Consumer USA 986 2,143 Santander Bank, National Association 647 1,828 Santander UK 584 7,147 Banco Santander Chile 540 589 Grupo Financiero Santander (Mexico) 426 460 Santander Consumer Nordics 210 496 Other entities 106 292 Total Goodwill 12,595 24,246 (*) The increase in 2020 arises from the repurchase of the pension plan and collective investment institution business from Banco Popular Español, S.A.U. to the Allianz Group (see Note 2). As mentioned in Note 1.c, the accounting standard (IAS 36) requires that a cash‑generating unit to which goodwill has been allocated is tested for impairment annually, and whenever there is an indication that the unit may be impaired. In the second quarter of 2020, having considered the updated economic and business environment resulting from COVID-19, the current market conditions and the existing economic uncertainty, an interim impairment test was performed as of 30 June 2020 for certain CGUs. As a result, the Group recognised EUR 10,100 million of goodwill impairment mainly related to the following CGUs: Santander UK, Santander Bank Polska, Santander Consumer USA, Santander Bank, National Association and Santander Consumer Nordics. In addition, during the first six months of 2020, goodwill decreased by EUR 1,897 million due to exchange differences (see Note 11). Impairment resulted from a combination of factors, including those related to COVID-19, and mainly the updated macroeconomic outlook which caused the Group to project lower earnings in some units but also reduce perpetual growth rate assumptions and increased discount rates used to estimate the value in use of such CGUs. Such impairment was recorded during the first six months of 2020 under the heading Impairment or reversal of impairment on non-financial assets, net -Intangible assets of the consolidated profit and loss account. The changes in goodwill were as follows: Million euros 2020 Balance at beginning of year 24,246 Additions 346 Of which: SAM Investment Holdings Limited (Note 2) 271 Impairment losses (10,100) Of which: Santander UK (6,101) Santander Bank Polska (1,192) Santander Consumer USA (1,153) Santander Bank, National Association (1,177) Santander Consumer Nordics (277) Disposals or changes in scope of consolidation — Exchange differences and other items (1,897) Balance at end of period 12,595 Following is a detail of the main assumptions which has been taken into account for determine the recoverable amount as of 30 June 2020 of the most significant cash-generating units which were valued using the discounted cash flow method and those used in 2019 year-end for comparison purposes: 30-06-2020 31-12-2019 Discount rate (*) Nominal perpetual growth rate Discount rate (*) Nominal perpetual growth rate Santander UK 9.4 % 2.3 % 8.5 % 2.5 % Santander Bank Polska 10.2 % 3.5 % 9.2 % 3.5 % Santander Consumer USA 10.6 % 1.5 % 9.5 % 1.5 % Santander Bank, National Association(**) 10.7 % 2.5 % 9.6 % 3.6 % Santander Consumer Nordics 9.9 % 2.0 % 8.6 % 2.5 % (*) Post-tax discount rate. (**) Weighted information of the main hypotheses of the segments that are allocated within the goodwill. For other significant CGUs where goodwill is not impaired as of 30 June 2020, the Group performs a sensitivity analysis, given the degree of uncertainty of certain assumptions, using reasonable changes in the key assumptions on which the recoverable amount of the cash-generating units is based in order to confirm whether their recoverable amount still exceeds their carrying amount. The sensitivity analysis involved adjusting the discount rate by +50 basis points and the perpetual growth rate by -50 basis points. Such sensitivity analysis was performed for other significant CGUs and considering reasonable changes in these key assumptions the value in use of all the cash-generating units still exceeds their recoverable amount. In addition, the Group analysed the recoverable amount of Banco Santander - Chile, Grupo Financiero Santander (México) and Banco Santander (Brasil) which is calculated as the fair values of the aforementioned cash-generating units obtained from the market prices of their shares at 30 June 2020. This value exceeded the recoverable amount. Based on the above, and in accordance with the estimates, forecasts and sensitivity analysis available to the managers of the Bank, during the first six months of 2020 the Group recognised goodwill impairment losses amounting to EUR 10,100 million (no impairment during the six month period ending 30 June 2019) under the heading Impairment or reversal of impairment on non-financial assets, net -Intangible assets of the consolidated profit and loss account. Goodwill is deducted from the CET1 for regulatory purposes, so an impairment of goodwill has no impact on the Group's capital ratios. Note 17 to the consolidated annual accounts for the year ended 31 December 2019 includes detailed information on the procedures followed by the Group to analyse the potential impairment of the goodwill recognised with respect to its recoverable amount and to recognise the related impairment losses, where appropriate.

Disclosure of provision matrix [abstract]
Provisions	Provisions a) Provisions for Pensions and other post-retirements obligations and Other long term employee benefits The variation experienced by the balance of the Pensions and other post-retirements obligations and other long term employee benefits from 31 December 2019 to 30 June 2020, is mainly due to payments for benefits in the first semester as well as the reduction of EUR 326 million partially due to the post-employment obligations assumed by the Group in Spain, as a result of the option offered to certain beneficiaries to anticipate the collection of lifetime pensions in the form of a single or deferred payment for up to 5 years, and to exchange rate changes (decrease in the Brazilian real). This negative change in the heading is partially offset by higher net actuarial losses as a result of changes in actuarial assumptions (see Note 11.c). b) Provisions for taxes and other legal contingencies and Other provisions Set forth below is the detail, by type of provision, of the balances at 30 June 2020 and at 31 December 2019 of Provisions for taxes and other legal contingencies and Other provisions. The types of provision were determined by grouping together items of a similar nature: Million euros 30-06-2020 31-12-2019 Provisions for taxes 581 759 Provisions for employment-related proceedings (Brazil) 591 776 Provisions for other legal proceedings 1,169 1,522 Provision for customer remediation 674 725 Regulatory framework-related provisions 21 67 Provision for restructuring 638 641 Other 896 1,018 4,570 5,508 Relevant information is set forth below in relation to each type of provision shown in the preceding table: The provisions for taxes include provisions for tax-related proceedings. The provisions for employment-related proceedings (Brazil) relate to claims filed by trade unions, associations, the prosecutor's office and ex-employees claiming employment rights to which, in their view, they are entitled, particularly the payment of overtime and other employment rights, including litigation concerning retirement benefits. The number and nature of these proceedings, which are common for banks in Brazil, justify the classification of these provisions in a separate category or as a separate type from the rest. The Group calculates the provisions associated with these claims in accordance with past experience of payments made in relation to claims for similar items. When claims do not fall within these categories, a case-by-case assessment is performed and the amount of the provision is calculated in accordance with the status of each proceeding and the risk assessment carried out by the legal advisers. The provisions for other legal proceedings include provisions for court, arbitration or administrative proceedings (other than those included in other categories or types of provisions disclosed separately) brought against Santander Group companies. The provisions for customer remediation include the estimated cost of payments to remedy errors relating to the sale of certain products in the UK and the estimated cost of the Banco Popular Español, S.A.U. floor clauses. To calculate the provision for customer remediation, the best estimate of the provision made by management is used, which is based on the estimated number of claims to be received and, of these, the number that will be accepted, as well as the estimated average payment per case. The regulatory framework-related provisions include mainly the provisions for the extraordinary contribution to FSCS ( Financial Services Compensation Scheme ) and the Bank Levy in the UK, and those relating to Banking Tax in Poland. The provisions for restructuring include only the direct costs arising from restructuring processes carried out by the various Group companies. Qualitative information on the main litigation is provided in Note 10.c. Our general policy is to record provisions for tax and legal proceedings in which we assess the chances of loss to be probable and we do not record provisions when the chances of loss are possible or remote. We determine the amounts to be provided for as our best estimate of the expenditure required to settle the corresponding claim based, among other factors, on a case-by-case analysis of the facts and the legal opinion of internal and external counsel or by considering the historical average amount of the loss incurred in claims of the same nature. The definitive date of the outflow of resources embodying economic benefits for the Group depends on each obligation. In certain cases, the obligations do not have a fixed settlement term and, in others, they depend on legal proceedings in progress. The changes in provisions arising from civil contingencies and legal nature are disclosed in this note. The main changes in provisions in the first six months of 2020 are as follows: Regarding the provisions for labor processes and others of a legal nature, Brazil has charged EUR 104 million and EUR 78 million, respectively, using provisions of EUR 82 million and EUR 55 million, respectively, and the rest of the deviation is due to currency depreciation. Regarding the provisions arising for customer remediation the United Kingdom has set aside EUR 6 million. On the other hand, EUR 43 million has been used in the United Kingdom. Additionally, EUR 14 million has been set aside in Poland to cover the mortgage portfolio in CHF in the first half of the year. Regarding in provisions constituted by regulatory framework, EUR 45 million in the first six months in United Kingdom has been used (Bank Levy and FSCS). In addition, EUR 64 million have been charged and paid in the first six months in Poland. In addition, in the provisions for restructuring, the United Kingdom has set aside EUR 39 million, EUR 7 million in Poland and EUR 21 million in Consumer Group. This increase is partially offset by the use of EUR 39 million and EUR 92 million in the United Kingdom and Spain, respectively. c) Litigation and other matters i. Tax-related litigation At 30 June 2020 the main tax-related proceedings concerning the Group were as follows: - Legal actions filed by Banco Santander (Brasil) S.A. and other Group entities to avoid the application of Law 9.718/98, which modifies the basis to calculate PIS and COFINS social contribution, extending it to all the entities income, and not only to the income from the provision of services. In relation of Banco Santander (Brasil) S.A. process, in May 2015 the Federal Supreme Court (FSC) admitted the extraordinary appeal filed by the Federal Union regarding PIS, and dismissed the extraordinary appeal lodged by the Brazilian Public Prosecutor's Office regarding COFINS contribution, confirming the decision of Federal Regional Court favourable to Banco Santander (Brasil) S.A. of August 2007. The appeals filed by the other entities before the Federal Supreme Court, both for PIS and COFINS, are still pending. These claims are fully provisioned.Banco Santander (Brasil) S.A. and other Group companies in Brazil have appealed against the assessments issued by the Brazilian tax authorities questioning the deduction of loan losses in their income tax returns (IRPJ and CSLL) in relation to different administrative processes of various years on the ground that the requirements under the applicable legislation were not met. The appeals are pending decision in CARF. No provision was recognised in connection with the amount considered to be a contingent liability. - Banco Santander (Brasil) S.A. and other Group companies in Brazil are involved in administrative and legal proceedings against several municipalities that demand payment of the Service Tax on certain items of income from transactions not classified as provisions of services. There are several cases in different judicial instances. A provision was recognised in connection with the amount of the estimated loss . - Banco Santander (Brasil) S.A. and other Group companies in Brazil are involved in administrative and legal proceedings against the tax authorities in connection with the taxation for social security purposes of certain items which are not considered to be employee remuneration. There are several cases in different judicial instances. A provision was recognised in connection with the amount of the estimated loss - In May 2003 the Brazilian tax authorities issued separate infringement notices against Santander Distribuidora de Títulos e Valores Mobiliarios Ltda. (DTVM, currently Santander Brasil Tecnologia S.A.) and Banco Santander (Brasil) S.A. in relation to the Provisional Tax on Financial Movements (CPMF) of the years 2000, 2001 and part of 2002. In July 2015, after the unfavourable decision of CARF, both entities appealed at Federal Justice in a single proceeding. In June 2019 this action has been dismissed, and the resolution has been appealed to the higher court. There is a provision recognised for the estimated loss. - In December 2010 the Brazilian tax authorities issued an infringement notice against Santander Seguros S.A. (Brazil), currently Zurich Santander Brasil Seguros e Previdência S.A., as the successor by merger to ABN AMRO Brasil dois Participações S.A., in relation to income tax (IRPJ and CSLL) for 2005, questioning the tax treatment applied to a sale of shares of Real Seguros, S.A. The administrative discussion ended unfavourably, and the CARF decision has been appealed at the Federal Justice. As the former parent of Santander Seguros S.A. (Brasil), Banco Santander (Brasil) S.A. is liable in the event of any adverse outcome of this proceeding. No provision was recognised in connection with this proceeding as it is considered to be a contingent liability. - In November 2014 the Brazilian tax authorities issued an infringement notice against Banco Santander (Brasil) S.A. in relation to corporate income tax (IRPJ and CSLL) for 2009 questioning the tax-deductibility of the amortisation of the goodwill of Banco ABN AMRO Real S.A. performed prior to the absorption of this bank by Banco Santander (Brasil) S.A., but accepting the amortisation performed after the merger. Actually it is appealed before the Higher Chamber of CARF. No provision was recognised in connection with this proceeding as it was considered to be a contingent liability. - Banco Santander (Brasil) S.A. has also appealed against infringement notices issued by the tax authorities questioning the tax deductibility of the amortisation of the goodwill arising on the acquisition of Banco Comercial e de Investimento Sudameris S.A from years 2007 to 2012. No provision was recognised in connection with this matter as it was considered to be a contingent liability. - Banco Santander (Brasil) S.A. and other companies of the Group in Brazil are undergoing administrative and judicial procedures against Brazilian tax authorities for not admitting tax compensation with credits derived from other tax concepts, not having registered a provision for such amount since it is considered to be a contingent liability. - Banco Santander (Brasil) S.A. is involved in appeals in relation to infringement notices initiated by tax authorities regarding the offsetting of tax losses in the CSLL (‘Social Contribution on Net Income’) of year 2009. The appeal is pending decision in CARF. No provision was recognised in connection with this matter as it is considered to be a contingent liability. The total amount for the aforementioned Brazil lawsuits related to tax legal obligations or with probable loss risk is approximately EUR 850 million, fully provisioned, and the total amount for tax litigation with possible loss risk is approximately EUR 3,047 million. - Banco Santander has appealed before European Courts the Decisions 2011/5/CE of 28 October 2009, and 2011/282/UE of 12 January 2011 of the European Commission, ruling that the deduction regulated pursuant to Article 12.5 of the Corporate Income Tax Law constituted illegal State aid. On November 2018 the General Court confirmed these Decisions but these judgements have been appealed at the Court of justice of the European Union. The dismissal of this appeal would not have effect on equity. At the date of approval of these interim financial statements certain other less significant tax-related proceedings were also in progress. ii. Non-tax-related proceedings At 30 June 2020, the main non-tax-related proceedings concerning the Group were as follows: - Payment Protection Insurance (PPI): claims associated with the sale by Santander UK plc of payment protection insurance or PPI to its customers. As of 30 June 2020, the remaining provision for PPI redress and related costs amounted to GBP 151 million (EUR 166 million) (2019: GBP 189 million (EUR 222 million)). There was no additional provision in the first semester of 2020. Given the passing of the Financial Conduct Authority’s deadline of 29 August 2019 for PPI complaints, the level of judgment required by management in determining appropriate assumptions has reduced. At 30 June 2020, the key assumptions in calculating the provision were around the estimated PPI penetration of August complaints. The uphold rates are informed by historical experience and the average cost of redress can be predicted reasonably accurately given that management is dealing with a high volume and reasonably homogenous population. Cumulative complaints from the inception of the PPI complaints process to 30 June 2020, regardless of the likelihood of Santander UK plc incurring a liability, were 4.5 millions. This includes 290,000 that were still being reviewed. Future expected complaints were 8,000. In addition, there are legal claims being made by Claims Management Companies challenging the FCA's industry guidance on the treatment of Plevin/recurring non-disclosure assessments. The provision for conduct remediation recognised represents management’s best estimate of Santander UK plc’s liability in respect of mis-selling of PPI policies. - Delforca: dispute arising from equity swaps entered into by Gaesco (now Delforca 2008, S.A.) on shares of Inmobiliaria Colonial, S.A. Banco Santander, S.A. is claiming to Delforca a total of EUR 66 million from the liquidation of the swaps. Mobiliaria Monesa, S.A. (Delforca’s parent company) has commenced a civil proceeding against the Bank claiming damages which, as of date have not been determined. The proceeding has been stayed because the jurisdiction of the Court has been challenged. Within insolvency proceedings before the Commercial Court, both Delforca and Mobiliaria Monesa have instigated a claim against the Bank seeking the recovery of EUR 56.8 million that the Bank received from the liquidation of the swap. The Bank has filed a claim against Delforca seeking the Bank's recognition of its right to receive the credit. At 30 June 2020, the risk is considered remote. The Bank has not recognised any provisions in this connectio n. - Former employees of Banco do Estado de São Paulo S.A., Santander Banespa, Cia. de Arrendamiento Mercantil: a claim was filed in 1998 by the association of retired Banespa employees (AFABESP) requesting the payment of a half-yearly bonus contemplated in the by-laws of Banespa in the event that Banespa obtained a profit and that the distribution of this profit were approved by the Board of Directors. The bonus was not paid in 1994 and 1995 since Banespa had not made a profit during those years. Partial payments were made from 1996 to 2000, as approved by the Board of Directors. The relevant clause was eliminated in 2001. The Regional Labor Court and the High Employment Court ordered Santander (Brasil) S.A., as successor to Banespa, to pay this half-yearly bonus for the period from 1996 to the present. On 20 March 2019, a decision from the Federal Court of Justice (Supremo Tribunal Federal, or “STF”) rejected the extraordinary appeal filed by Santander Brasil. A rescission action was brought to revert the decision in the main proceedings and suspend procedural enforcement. The external legal advisor of the Bank has classified the risk of loss as probable. The current court decision does not define a specific amount to be paid by the defendants (this would only be determined once a final decision is issued and the enforcement process has begun). - “Planos Económicos”: like the rest of the banking system in Brasil, Santander Brasil has been the target of customer complaints and collective civil suits stemming from legislative changes and its application to bank deposits, fundamentally ('economic plans'). At the end of 2017, there was an agreement between regulatory entities and the Brazilian Federation of Banks (Febraban), already approved by the Supremo Tribunal Federal, with the purpose of closing the lawsuits. Discussions focused on specifying the amount to be paid to each affected client according to the balance in their notebook at the time of the Plan. Finally, the total value of the payments will depend on the number of endorsements they have made and the number of savers who have demonstrated the existence of the account and its balance on the date the indexes were changed. In November 2018, the STF ordered the suspension of all economic plan processes for two years from May 2018. On May 29, 2020, the Supremo Tribunal Federal approved the extension of the agreement for 5 additional years starting from 3 June 2020. Condition for this extension was to include in the agreement actions related to the "Collor I Plan". The provisions recorded for the economic plan processes are considered to be sufficient. - Floor clauses (“cláusulas suelo”): in consequence of the acquisition of Banco Popular Español, S.A.U, the Group has been exposed to a material number of transactions with floor clauses. The so-called "floor clauses" or minimum clauses are those under which the borrower accepts a minimum interest rate to be paid to the lender, regardless of the applicable reference interest rate. Banco Popular Español, S.A.U. included "floor clauses" in certain asset transactions with customers. In relation to this type of clauses, and after several rulings made by the Court of Justice of the European Union and the Spanish Supreme Court, and the extrajudicial process established by the Spanish Royal Decree-Law 1/2017, of 2 January, Banco Popular Español, S.A.U. made extraordinary provisions that were updated in order to cover the effect of the potential return of the excess interest charged for the application of the floor clauses between the contract date of the corresponding mortgage loans and May 2013. The Group considered that the maximum risk associated with the floor clauses applied in its contracts with consumers, in the most severe and not probable scenario, would amount to approximately EUR 900 million, as initially measured and without considering the returns performed. For this matter, after the purchase of Banco Popular Español, S.A.U., EUR 402 million provisions have been used by the Group (EUR 238 million in 2017, EUR 119 million in 2018 and EUR 45 million in 2019) mainly for refunds as a result of the extrajudic ial process mentioned above. As of 30 June 2020, the amount of the Group's provisions in relation to this matter amounts to EUR 80 million (31 December 2019: EUR 80 million). - Banco Popular´s acquisition: considering the declaration setting out the resolution of Banco Popular Español, S.A.U., the redemption and conversion of its capital instruments and the subsequent transfer to Banco Santander, S.A. of the shares resulting from this conversion in exercise of the resolution instrument involving the sale of the institution's business, in the application accordance with the single resolution framework regulation referred to in Note 3 of the 2019 consolidated annual accounts, some investors have filed claims against the EU’s Single Resolution Board decision, the FROB's resolution executed in accordance to the aforementioned decision, and claims have been filed and may be filed in the future against Banco Santander, S.A. or other Santander Group companies deriving from or related to the acquisition of Banco Popular Español, S.A.U.. At this stage, it is not possible to foresee the total number of claims that could be filed by the former holders of shares and capital instruments (arising from the acquisition by investors of such shares and capital instruments of Banco Popular Español, S.A.U. prior to resolution, including in particular, without limitation, the shares acquired in the context of the capital increase with pre-emptive subscription rights carried out in 2016), and their economic implications (especially considering that the decision to resolve in application of the new regulation has no precedent, and that it may be possible that future claims do not specify a specific amount, put forward new legal interpretations or involve a large number of parties). The estimated cost of any compensation to shareholders and bondholders of Banco Popular recognised in 2017 amounted to EUR 680 million, of which EUR 535 million were applied to the commercial loyalty program. The provisions recorded are considered sufficient to cover the risks associated with the court claims currently being dealt with. However, if additional amounts have to be paid for claims already raised with an undetermined economic interest or for new claims, this could have a significant adverse effect on the Santander Group's results and financial situation. Likewise, the Central Court of Instruction 4 is currently conducting preliminary proceedings 42/2017, in which, amongst other things, is being investigated the following: (i) the accuracy of the prospectus for the capital increase with pre-emptive subscription rights carried out by Banco Popular in 2016; And (ii) the alleged manipulation of the share price of Banco Popular until the resolution of the bank, in June 2017. During the course of the proceedings, on 15 January 2019, the Spanish National Court, applying article 130.2 of the Spanish Criminal Code, declared the Bank the successor entity to Banco Popular Español, S.A.U. (following the merger of the Bank and Banco Popular Español, S.A.U. on 28 September 2018), and, as a result, determined that the Bank assumed the role of the party being investigated in the criminal proceeding. The decision was appealed and on 30 April 2019, the Spanish National Court ruled in favor of Banco Santander, S.A. declaring that Banco Santander, S.A. cannot inherit Banco Popular’s potential criminal liability. This ruling was appealed before the Supreme Court who have rejected the appeal. In this procedure, Banco Santander has the status of possible subsidiary civil liability. - German shares investigation: the Cologne Public Prosecution Office is conducting an investigation against the Bank, and other group entities based in UK - Santander UK plc, Santander Financial Services Plc and Cater Allen International Limited -, in relation to a particular type of tax dividend linked transactions known as cum-ex transactions. The Group is cooperating with the German authorities. According to the state of the investigations, the results and the effects for the Group, which may potentially include the imposition of financial penalties, cannot be anticipated. The Bank has not recognised any provisions in relation to the potential imposition of financial penalties. - Attorneys General Investigation of auto loan securitisation transactions and fair lending practices: in October 2014, May 2015, July 2015 and February 2017, Santander Consumer USA Inc. (SC) received subpoenas and/or Civil Investigative Demands (CIDs) from the Attorneys General of the U.S. states of California, Illinois, Oregon, New Jersey, Maryland and Washington under the authority of each state's consumer protection statutes. These states serve on behalf of a group of 33 state Attorneys General. The subpoenas and CIDs contained broad requests for information and the production of documents related to SC’s underwriting, securitization, the recovery efforts servicing and collection of non prime vehicle loans. SC responded to these requests within the deadlines specified and has otherwise cooperated with the Attorneys General with respect to this matter. On 19 May 2020, SC entered into settlements with all the attorneys general resolving this investigation. SC is fully reserved for the settlement. - Financial Industry Regulatory Authority (“FINRA”) Puerto Rico Arbitrations: as of 30 June 2020, Santander Securities LLC (SSLLC) had receiv ed 764 FINRA arbitration cases related to Puerto Rico Bonds issued by public and public related entities, as well as Puerto Rico closed-end funds (CEFs). The statements of claims allege, among other things, fraud, negligence, breach of fiduciary duty, breach of contract, unsuitability, over-concentration of the investments and failure to supervise. There were 346 arbitration cases that remained pending as of 30 June 2020. As a result of various legal, economic and market factors impacting or that could impact of the value Puerto Rico bonds and CEFs, it is possible that additional arbitration claims and/or increased claim amounts may be asserted against SSLLC in future periods. The provisions recorded for these matters are considered sufficient. - IRPH Index: a portion of our Spanish mortgage loan portfolio bears interest at a rate indexed to the “Índice de Referencia de Préstamos Hipotecarios” known as “IRPH” which, at the time the contracts were entered into, served as reference rate for many mortgage loan agreements in Spain and was published by the Bank of Spain. Consumers in Spain have brought lawsuits against most of the Spanish banking sector alleging that the use and related disclosures of such rate did not comply with the transparency requirements of European regulation. On 14 December 2017, the Supreme Court of Spain ruled that these clauses were valid, as the IRPH is an official rate and therefore non-subject to transparency requirements. The matter was referred to the Court of Justice of the European Union through a preliminary ruling procedure. On 3 March 2020 the CJUE rendered its decision. The CJUE ruled that, being the IRPH a valid index, national courts are entitled to examine its use on each particular contract in order to verify whether the transparency requirements have been met. When carrying out the transparency control, national courts have to take into account all the circumstances surrounding the conclusion of the particular contract, including whether essential information relating to the calculation of that rate was easily accessible and the provision of data relating to past fluctuations of the index. Finally, with regard to the effects of nullity of an IRPH index clause, the CJUE entitles national courts to substitute it with another statutory index, thus not declaring the nullity of the whole contact. While the uncertainty regarding the effects of the CJUE judgment remain, it is expected that national courts will follow the case-law set by the Spanish Supreme Court in 2017. Therefore, it is not possible still to est imate the potential exposure. Currently, the balance of the relevant mortgage loans held by us equals approximately EUR 3,254 million. - Banco Santander, S.A. has been sued in a legal proceeding in which the plaintiff alleges that a contract was concluded whereby he would be entrusted with the functions of CEO of the Bank. In the complaint, the claimant mainly requests a declaratory ruling that affirms the validity and conclusion of such contract and its enforcement together with the payment of certain amounts. If the main request is not granted, the claimant seeks compensation for a total amount of approximately EUR 112 million or, an alternative relief for other minor amounts. Banco Santander, S.A. has answered to the complaint. In this answer, it is stated that the conditions to which the appointment was subject to were not met and that the contract required by law was not concluded. The proceeding is ongoing. - CHF Polish Mortgage Loans: On 3 October 2019, the Court of Justice of the European Union (CJEU) rendered its decision in relation to a lawsuit against an unrelated bank in Poland, with regards to unfair contractual clauses in consumer agreements, specifically the consequences of potentially unfair contractual clauses in CHF-indexed loan agreements. The CJEU has left to Polish courts the decision on whether the whole contract can be maintained once the abusive terms have been removed, which should in turn decide whether the effects of the annulment of the contract are prejudicial to the consumer. In that case, the court may only integrate the contract with default provisions of national law and decide, in accordance with those provisions, on the applicable rate. As at 30 June 2020, the Group has a portfolio of mortgage loans denominated in, or indexed to, CHF of approximately PLN 10,114 million (EUR 2,276 million). In 2019 the Group (Santander Bank Polska S.A. and Santander Consumer Bank S.A.) in Poland created PLN 173 million (EUR 40.9 million) provision for CHF. On June 2020, the provision was increased by PLN 63.2 million (EUR 14.2 million).This provision represents the best estimate to date given the difficulty to predict the financial impact, as, it is for national courts to decide the relevant issues. The Bank and the other Group companies are subject to claims and, therefore, are party to certain legal proceedings incidental to the normal course of their business including those in connection with lending activities, relationships with employees and other commercial or tax matters. With the information available to it, the Group considers that, at 30 June 2020, it had reliably estimated the obligations associated with each proceeding and had recognised, where necessary, sufficient provisions to cover reasonably any liabilities that may arise as a result of these tax and legal risks. Subject to the qualifications made, it also believes that any liability arising from such claims and proceedings will not have, overall, a material adverse effect on the Group’s business, financial position or results of operations.

Equity [abstract]
Equity	Equity In the first six months ended 30 June 2020 and 2019 there were no quantitative or qualitative changes in the Group's equity other than those indicated in the condensed consolidated statements of changes in total equity. a) Capital As of 30 June 2020 and 31 December 2019, the Bank's capital stock was represented by 16,618,114,582 shares, with a nominal amount of EUR 8,309 million, in both dates. b) Breakdown of other comprehensive income - Items not reclassified to profit or loss and Items that may be reclassified to profit or loss Million euros 30-06-2020 31-12-2019 (*) Other comprehensive income accumulated (30,637) (24,168) Items not reclassified to profit or loss (5,010) (4,288) Actuarial gains or losses on defined benefit pension plans (4,756) (4,764) Non-current assets held for sale — — Share in other income and expenses recognised in investments, joint ventures and associates (6) 1 Other valuation adjustments — — Changes in the fair value of equity instruments measured at fair value with changes in other comprehensive income (257) 514 Inefficacy of fair value hedges of equity instruments measured at fair value with changes — — Changes in the fair value of equity instruments measured at fair valuewith changes 166 44 Changes in the fair value of equity instruments measured at fair value with changes (166) (44) Changes in the fair value of financial liabilities measured at fair value through profit or loss 9 (39) Items that may be reclassified to profit or loss (25,627) (19,880) Hedge of net investments in foreign operations (effective portion) (2,940) (5,464) Exchange differences (25,450) (16,701) Hedging derivatives (effective portion) 846 300 Changes in the fair value of debt instruments measured at fair value with changes in other comprehensive income 2,465 2,321 Hedging instruments (items not designated) — — Non-current assets held for sale — — Share in other income and expenses recognised in investments, joint ventures and associates (548) (336) (*) See Note 1.e. c) Other comprehensive income - Items not reclassified to profit or loss - Actuarial gains or losses on defined benefit pension plans The changes in the balance of Other comprehensive income - Items not reclassified to profit or loss - Actuarial gains or losses on defined benefit pension plans include the actuarial gains or losses generated in the period and the return on plan assets, excluding amounts included in net interest on the net defined benefit liability (asset), less the administrative expenses and taxes inherent to the plan, and any change in the effect of the asset ceiling. Its variation is shown in the condensed consolidated statement of recognised income and expense. During the first si x months of 2020, the amount of actuarial losses (net of actuarial gains) has decreased by EUR 204 million. The main impacts are: • Increase of EUR 437 million in the accrued actuarial losses relating to the Group's businesses in the United Kingdom, mainly due to the change in the discount rate (decrease from 2.11% to 1.44%). • Decrease of EUR 267 million in the accrued actuarial losses relating to the Group's businesses in the Brazil, mainly due to the change in the discount rate (increase from 7.05% to 7.46%, for pension plans and from 7.22% to 7.78% for medical plans). • Increase of EUR 43 million in the accrued actuarial losses relating to the Group's businesses in the Spain, due to the change in the mortality tables, which has been partially offset by demographic gains. The remaining variation in the accrued actuarial gains and losses heading represents a decrease of EUR 417 million, as a result of the evolution of exchange rates, mainly in the depreciation of the Brazilian real and other effects. d) Other comprehensive income - Items not reclassified to profit or loss – Changes in the fair value of equity instruments measured at fair value with changes in other comprehensive income Includes the net amount of unrealised fair value changes in equity instruments at fair value with changes in other comprehensive income. Below is a breakdown of the composition of the balance as of 30 June 2020 under “Other comprehensive income - Items not reclassified to profit or loss - Changes in the fair value of equity instruments measured at fair value with changes in other global result depending on the geographical origin of the issuer”: Million euros 30-06-2020 31-12-2019 Revaluation gains Revaluation losses Net revaluation gains/(losses) Fair value Revaluation gains Revaluation losses Net revaluation gains/(losses) Fair value Equity instruments Domestic Spain 20 (794) (774) 141 21 (445) (424) 184 International Rest of Europe 62 (74) (12) 308 68 (72) (4) 379 United States 15 (3) 12 43 15 (3) 12 44 Latin America and rest 524 (7) 517 1,736 934 (4) 930 2,256 621 (878) (257) 2,228 1,038 (524) 514 2,863 Of which: Listed 525 (42) 483 1,756 936 (14) 922 2,283 Unlisted 96 (836) (740) 472 102 (510) (408) 580 e) Other comprehensive income - Items that may be reclassified to profit or loss – Hedges of net investments in foreign operations (effective portion) and exchange differences Other comprehensive income - Items that may be reclassified to profit or loss - Hedges of net investments in foreign operations (effective portion) includes the net amount of the changes in value of hedging instruments in hedges of net investments in foreign operations, in respect of the portion of these changes considered to be effective hedges. Other comprehensive income - Items that may be reclassified to profit or loss - Exchange differences includes the net amount of exchange differences arising on non-monetary items whose fair value is adjusted against equity and the differences arising on the translation to euros of the balances of the consolidated entities whose functional currency is not the euro. The net variation of both headings recognised during the first six months of 2020, recorded in the statement of income and expenses recognised as a consolidated summary, reflects the impact of the evolution of currencies in the year , as a consequence of the generalized depreciation of the main currencies (see Note 1.e). From this variation, a loss of EUR 1,897 million corresponds to the valuation at the closing exchange rate of goodwill of the six months (see Note 8). f) Other comprehensive income – Items that may be reclassified to profit or loss – Changes in the fair value of debt instrument s measured at fair value through other comprehensive income Includes the net amount of unrealised fair value changes in debt instruments at fair value through other comprehensive income. Below is a breakdown of the composition of the balance as of 30 June 2020 and 31 December 2019 under Other comprehensive income - Items that may be reclassified to profit or loss - Changes in the fair value of debt instruments measured at fair value through other comprehensive income depending on the type of instrument and the geographical origin of the issuer: Million euros 30-06-2020 31-12-2019 Revaluation gains Revaluation losses Net revaluation gains/(losses) Fair value Revaluation gains Revaluation losses Net revaluation gains/(losses) Fair value Debt instruments Government and central banks Spain 862 — 862 23,167 947 (2) 945 32,413 Rest of Europe 792 (69) 723 17,993 664 (38) 626 19,052 Latin America and rest of the world 893 (119) 774 51,697 839 (121) 718 51,284 Private-sector debt instruments 156 (50) 106 27,475 81 (49) 32 20,096 2,703 (238) 2,465 120,332 2,531 (210) 2,321 122,845

Disclosure of operating segments [abstract]
Segment Information (Primary segment)	Segment information (Primary segment) For Group management purposes, the primary level of segmentation, which is based on the Group's management structure, comprises five reportable segments: four operating areas plus the Corporate Center. The operating areas are: Europe, South America, North America and Santander Global Platform. Following is the breakdown of revenue that is deemed to be recognised under Dividend income, Commission income, Gain or losses on financial assets and liabilities not measured at fair value through profit or loss, net, Gain or losses on financial assets and liabilities held for trading, net, Gain or losses on non-trading financial assets and liabilities mandatorily at fair value through profit or loss, Gain or losses on financial assets and liabilities measured at fair value through profit or loss, net, Gain or losses from hedge accounting, net, Other operating income and Income from assets under insurance and reinsurance contracts in the accompanying consolidated income statements for the first six months ended 30 June 2020 and 2019. This financial information (“underlying basis”) is computed by adjusting reported results for the effects of certain gains and losses (e.g.: capital gains, write-downs, etc.). These gains and losses are items that management and investors ordinarily identify and consider separately to understand better the underlying trends in the business.

In cases where price quotations cannot be observed, management makes its best estimate of the price that the market would set, using its own internal models. In most cases, these internal models use data based on observable market parameters as significant inputs (Level 2) and, in some cases, they use significant inputs not observable in market data (Level 3). In order to make these estimates, various techniques are employed, including the extrapolation of observable market data. The best evidence of the fair value of a financial instrument on initial recognition is the transaction price, unless the fair value of the instrument can be obtained from other market transactions performed with the same or similar instruments or can be measured by using a valuation technique in which the variables used include only observable market data, mainly interest rates. During the first six months of 2020 , the Group did not make any material transfers of financial instruments between measurement levels other than the transfers included in level 3 table. The Group has developed a formal process for the systematic valuation and management of financial instruments, which has been implemented worldwide across all the Group's units. The governance scheme for this process distributes responsibilities between two independent divisions: Treasury (development, marketing and daily management of financial products and market data) and Risk (on a periodic basis, validation of pricing models and market data, computation of risk metrics, new transaction approval policies, management of market risk and implementation of fair value adjustment policies). The approval of new products follows a sequence of steps (request, development, validation, integration in corporate systems and quality assurance) before the product is brought into production. This process ensures that pricing systems have been properly reviewed and are stable before they are used. The most important products and families of derivatives, and the related valuation techniques and inputs, by asset class, are detailed in the consolidated annual accounts as at 31 December 2019. As of 30 June 2020, the CVA (Credit Valuation Adjustment) accounted for was EUR 477.4 million (an increase of 75.5% compared to 31 December 2019 year end) and adjustments of DVA (Debt Valuation Adjustment) was EUR 250.1 million (46.2% compar ed to 31 December 2019). During the last quarter the main credit spreads were reduced by almost 30% although the markets still reflect levels much higher than those at the start of the COVID-19 pandemic.

(**) Includes mainly short-term loans and reverse repurchase agreements with corporate customers (mainly brokerage and investment companies). (***) Includes credit risk derivatives with a negative net fair value of EU R 0 and EUR 6 million recognised in the interim condensed consolidated balance sheet 30 June 2020 and 31 December 2019. These assets and liabilities are measured using the Standard Gaussian Copula Model. (****) Includes residential mortgages to financial institutions in the United Kingdom (which are regulated and partly financed by the Government). The fair value of these loans has been obtained using observable market variables, including current market transactions of similar amount and guarantees provided by the UK Housing Association. Given that the Government is involved in these entities, credit risk spreads have remained stable and homogeneous in this sector. The results arising from the valuation model are contrasted against current market transactions. The measurements obtained using the internal models might have been different had other methods or assumptions been used with respect to interest rate risk, to credit risk, market risk and foreign currency risk spreads, or to their related correlations and volatilities. Nevertheless, the Bank’s directors consider that the fair value of the financial assets and liabilities recognised in the consolidated balance sheet and the gains and losses arising from these financial instruments are reasonable. Level 3 financial instruments Set forth below are the Group's main financial instruments measured using unobservable market data that constitute significant inputs of the internal models (Level 3): - Instruments in Santander UK's portfolio (loans, debt instruments and derivatives) linked to the House Price Index (HPI). Even if the valuation techniques used for these instruments may be the same as those used to value similar products (present value in the case of loans and debt instruments, and the Black-Scholes model for derivatives), the main factors used in the valuation of these instruments are the HPI spot rate, the growth rate of that rate, its volatility and mortality rates, which are not always observable in the market and, accordingly, these instruments are considered illiquid: • The HPI spot rate: for some instruments the NSA HPI spot rate, which is directly observable and published on a monthly basis, is used. For other instruments where regional HPI rates must be used (published quarterly), adjustments are made to reflect the different composition of the rates and adapt them to the regional composition of Santander UK's portfolio. • HPI growth rate: this is not always directly observable in the market, especially for long maturities, and is estimated in accordance with existing quoted prices. To reflect the uncertainty implicit in these estimates, adjustments are made based on an analysis of the historical volatility of the HPI, incorporating reversion to the mean. • HPI volatility: the long-term volatility is not directly observable in the market but is estimated on the basis of more short-term quoted prices and by making an adjustment to reflect the existing uncertainty, based on the standard deviation of historical volatility over various time periods. • Mortality rates: these are based on published official tables and adjusted to reflect the composition of the customer portfolio for this type of product at Santander UK. - Callable interest rate trading derivatives (Bermudan style options) where the main unobservable input is mean reversion of interest rates. - Derivatives of negotiation on interest rates, taking asset securitisations and with the redemption rate (CPR) as the main unobservable input as an underlying asset. - Derivatives from trading on inflation in Spain, where volatility is not observable in the market. - Derivatives on long-term interest rate volatility and FX where volatility is not observable in the market at the indicated term. - Equity volatility derivatives, specifically indices and equities, where volatility is not observable in the long term. - Derivatives on long-term interest rate and FX in some Latam units (mainly Brazil), where for certain underlyings it is not possible to demonstrate observability to these terms. - Debt instruments in Latam units linked to certain illiquid interest rates, for which there is no reasonable market observability. - Illiquid equity in non-trading portfolios, classified at fair value through profit or loss and at fair value through equity. - Syndicated loans with the HTC&S business model (Hold to collect and sale) and classified in the fair value category with changes in other accumulated global result, where the cost of liquidity is not directly observable in the market, as well as the prepayment option in favour of the borrower. - Loans mandatorily at fair value through profit and loss in SCUSA, for which there are no observable market prices and certain valuation inputs associated with their credit risk are also unobservable. The net amount recorded in the results of the first six months of 2020 resulting from the aforementioned valuation models which main inputs are unobservable market data (Level 3) amounts to EUR 56 million benefit approximately (EUR 68 million in the first six months of 2019). The table below shows the effect, at 30 June 2020, on the fair value of the main financial instruments classified as Level 3 of a reasonable change in the assumptions used in the valuation. This effect was determined by applying the probable valuation ranges of the main unobservable inputs detailed in the following table: Portfolio/Instrument Valuation technique Main unobservable inputs Range Weighted average Impacts (in million euros) (Level 3) Unfavourable scenario Favorable scenario Financial assets held for trading ( assets) Trading derivatives Present Value Method Curves on TAB indixes(*) (a) (a) (0.2) 0.2 Present Value model, modified Black-Scholes HPI forward growth rate 0%-5% 2.53% (22.8) 22.2 HPI spot n/a 427.73 (**) (8.3) 8.3 Caps/Floors Black Model No interest rate curve observable in the market.

(a) The exercise was conducted for the unobservable inputs described in the “main unobservable inputs” column under probable scenarios. The range and weighted average value used are not shown because the aforementioned exercise was conducted jointly for various inputs or variants thereof (e.g. the TAB input comprises vector-time curves, for which there are also nominal yield curves and inflation-indexed yield curves), and it was not possible to break down the results separately by type of input. In the case of the TAB curve the gain or loss is reported for changes of +/-100b.p. for the total sensitivity to this index in CLP and CLF. The same is applicable to the MXN interest rates. (b) The Group calculates the potential impact on the measurement of each instrument on a joint basis, regardless of whether the individual value is positive (assets) or negative (liabilities), and discloses the joint effect associated with the related instruments classified on the asset side of the consolidated balance sheet. * Note: Null impacts in Quanto options arise because the position is completely covered back.to-back. Null impacts on Interest Rate Swaps (Swaps Lock In) arise because the prepaid risk is fully covered.

Disclosure of reclassifications or changes in presentation [abstract]
Basis of presentation of the interim financial statements	Basis of presentation of the interim financial statements Under Regulation (EC) no. 1606/2002 of the European Parliament and of the Council of 19 July 2002, all companies governed by the law of an EU Member State and whose securities are admitted to trading on a regulated market of any Member State must prepare their consolidated annual accounts for the years beginning on or after 1 January 2005 in accordance with the International Financial Reporting Standards (“IFRSs”) as previously adopted by the European Union (“EU-IFRSs”). In order to adapt the accounting system of Spanish credit institutions to these standards, the Bank of Spain issued Circular 4/2004, of 22 December, on Public and Confidential Financial Reporting Rules and Formats, which was repealed on 1 January 2018 by Bank of Spain Circular 4/2017, of 27 November 2017, and subsequent modifications. The consolidated annual accounts for 2019 were approved at the board of directors meeting on 27 February 2020 in compliance with International Financial Reporting Standards as adopted by the European Union, taking into account Bank of Spain Circular 4/2017, and subsequent modifications, using the basis of consolidation, accounting policies and measurement bases described in Note 2 to the aforementioned consolidated annual accounts and, accordingly, they presented fairly the Group’s consolidated equity and consolidated financial position at 31 December 2019 and the consolidated results of its operations, and the consolidated cash flows in 2019. The aforementioned consolidated annual accounts, which are included in the Group’s Form 20-F filed with the U.S. Securities and Exchange Commission on 6 March 2020, and these interim financial statements are also in compliance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS-IASB”, and together with EU-IFRS, “IFRS”). These interim financial statements were prepared and are presented in accordance with International Accounting Standard (IAS 34), Interim Financial Reporting, for the preparation of interim condensed financial statements, in conformity with Article 12 of Royal Decree 1362/2007, and taking into account the requirements of Circular 3/2018, of 28 June, of the Spanish National Securities Market Commission (“CNMV”). The aforementioned interim financial statements were included in the half-year financial report for the first six months of 2020 to be presented by the Group in accordance with the Circular 3/2018. In accordance with IAS 34, the interim financial statements are intended only to provide an update on the content of the latest consolidated annual accounts authorised for issue, focusing on new activities, events and circumstances occurring during the first six months, and does not duplicate information previously reported in the latest consolidated annual accounts. Consequently, these interim financial statements do not include all the information that would be required for a complete set of consolidated annual accounts prepared in accordance with IFRSs and, accordingly, for a proper comprehension of the information included in these interim financial statements, they should be read together with the Group’s consolidated annual accounts for the year ended 31 December 2019. Santander Group policies include presenting the interim financial statements for its use in the different markets using the Euro as its presentation currency. The amounts held in other currencies and the balances of entities whose functional currency is not the Euro, have been translated to the presentation currency in accordance with the criteria indicated in Note 2.a to the consolidated annual accounts for 2019. As indicated in that Note, for practical reasons, the balance sheet amount has been converted to the closing exchange rate, the equity to the historical type, and the income and expenses have been converted by applying the average exchange rate of the period; the application of such exchange rate or that corresponding to the date of each transaction does not lead to significant differences in the interim financial statements of the Group. The accounting policies and methods used in preparing these interim financial statements are the same as those applied in the consolidated annual accounts for 2019, taking into account the standards and interpretations that became applicable during the first six months of 2020, which are detailed below: - Modification of IFRS conceptual framework: The IFRS Framework, which sets out the fundamental concepts of financial reporting, is amended. The revised Framework includes: a new chapter about measurement; guidance on financial reporting; improved definitions, in particular the definition of liabilities; and clarifications such as management functions, prudence and measurement uncertainty in financial reporting. - Modification of IAS 1 Presentation of financial statements and IAS 8 Accounting policies, changes in accounting estimates and errors, which use a consistent definition of materiality, for the purpose of making material judgements and deciding on the information to be included in the financial statements. - Modification of IFRS 3 Business combinations - amendments are introduced. The amendments are intended to assist entities to determine whether a transaction should be accounted for as a business combination or as an asset acquisition. IFRS 3 continues to adopt a market participant’s perspective to determine whether an acquired set of activities and assets is a business. The amendments are mainly due to: clarify the minimum requirements for a business; remove the assessment of whether market participants are capable of replacing any missing elements; add guidance to help entities assess whether an acquired process is substantive; narrow the definitions of a business and of outputs; and introduce an optional fair value concentration test. The aforementioned amendments to accounting standards and interpretations have not had a significant effect on the Group’s financial statements. All accounting policies and measurement bases with a material effect on the interim financial statements for 30 June 2020 were applied in their preparation. By the time of the preparation and authorisation of these interim financial statements, there was the following standard to be adopted by the European Union whose effective date of implementation by the IASB is 1 January 2020. - Modification of IFRS 16 Leases - amendments are introduced. The amendment provides a practical expedient that permits leases not to assess whether rent concessions that occur as a direct consequence of the COVID-19 pandemic and meet specific conditions are lease modifications and, instead, to account for those rent concessions as if they were not lease modifications. The effective date of entry into force of this amendment is 1 June 2020, allowing early implementation. No significant effects on the Group's interim financial statements are expected from the future application of the aforementioned amendments to the accounting standard.
Use of critical estimates	Use of critical estimates The consolidated results and the determination of the consolidated equity are sensitive to the accounting principles and policies, valuation criteria and estimates used by the directors of the Bank in preparing the interim financial statements. The main accounting principles, policies, and valuation criteria are indicated in Note 2 of the consolidated annual accounts of the year 2019, except for those indicated in these interim financial statements due to the rules that have come into effect during the first six months of the year 2020. The interim financial statements contain estimates made by the senior management of the Bank and of the consolidated entities in order to quantify certain of the assets, liabilities, income, expenses and obligations reported herein. These estimates, which were made on the basis of the best information available, relate mainly to the following: 1. The income tax expense, which, in accordance with IAS 34, is recognised in interim periods based on the best estimate of the weighted average tax rate expected by the Group for the full financial year; 2. The impairment losses on certain assets – Financial assets at fair value through other comprehensive income, financial assets at amortised cost, non-current assets held for sale, investments in subsidiaries, joint ventures and associates, tangible assets and intangible assets; 3. The assumptions used in the calculation of the post-employment benefit liabilities and commitments and other obligations; 4. The useful life of the tangible and intangible assets; 5. The measurement of goodwill impairment arising on consolidation; 6. The calculation of provisions and the consideration of contingent liabilities; 7. The fair value of certain unquoted assets and liabilities; 8. The recoverability of deferred tax assets; and 9. The fair value of the identifiable assets acquired and the liabilities assumed in business combinations in accordance with IFRS3. To update the above estimates, the Group's management has considered that since March 2020, COVID-19, a new strain of Coronavirus, has spread to many countries, including Spain. This event has resulted the viral outbreak to be classified as a pandemic by the World Health Organization, which significantly affects economic activity worldwide and, as a result, the Group's operations and financial results. While there has been a worsening of the macroeconomic outlook to date, the extent to which COVID-19 will ultimately impact the Group's results will depend on future developments, including actions to contain or treat the disease and mitigate its impact on the economies of the affected countries, which generate uncertainties in the Group’s estimates. For this reason, the Group's management has assessed the current situation according to the best information available, then developing the potential impacts of COVID-19 on the estimates made during the first six months ended 30 June 2020. From the results of this evaluation, the following aspects stand out: - Estimation of expected credit losses: Context The COVID-19 health crisis has been unexpected, unpredictable and severe, but it is estimated to be of a limited temporary nature. The Group's priority in these circumstances has been to look after the health of its employees, customers and shareholders, but also to help reduce the economic impact that the coronavirus pandemic may have. This includes trying to offer the best solutions to help individual customers and businesses. Conceptually, the phases in managing the effects of COVID-19 have been: – Identification of customers or groups affected or potentially affected by the pandemic. – Early relief of temporary financial difficulties caused by COVID-19 through measures promoted by governments, central banks, and financial institutions. – Monitoring the evolution of customers, to ensure that they continue to be provided with the best solution for their situation, and also to guarantee that their potential impairment is correctly reflected in the Group's risk management and accounting. – Monitoring is accompanied by recovery management activities when necessary. These conceptual phases do not occur sequentially but overlap in time. Additionally, the continuous interaction and coordination between the different local units of the Group is proving to be a fundamental asset in the management of this crisis. The experience obtained in the fight against the health crisis and its financial consequences in our different geographies, and the different speeds at which it has been developing in each of them, allow us to share the best practices identified and to implement in an agile and efficient manner those strategies and concrete actions that have been most successful, always adapted to the local reality of each market. Measures to support the economy In accordance with the comments made earlier regarding the relief of our clients' temporary financial difficulties caused by the pandemic, the Group has adopted measures to foster the economic resilience of our clients during the crisis in all regions. The most outstanding of these include the following: – Providing liquidity and credit facilities to companies facing difficulties. – Facilitate grace periods or moratoriums in many of their markets. – Temporary option to increase the limit on credit cards and overdrafts. – Support vulnerable customers (elderly, SMEs, etc.) by being proactive and trying to cover their needs. – Temporary reduction or suspension of commissions (when withdrawing money from ATMs, on interest-free online purchases, on bank transfers...). – Guaranteeing COVID-19 coverage in health insurance. – Specialized teams to advise clients in financial difficulties. Regarding specific liquidity measures, shortages or moratoriums, the Group has implemented a series of support programmes in accordance with the guidelines set by regulatory and supervisory authorities, as well as by governments, central banks and supranational entities. The main objective is to mitigate the temporary impact on the activity of our customers, since the absence of appropriate measures and their adequate prudential and accounting treatment could worsen the economic consequences of the crisis, generating procyclical effects that would lengthen its duration and impact. The different measures offered can be grouped into the following categories: – Government liquidity measures: Generally speaking, these are lending facilities provided by the bank to legal entities, which have government guarantees on a specific percentage of the exposure generated in the event of default. Examples of this type of measure include ICO ( Instituto de Crédito Oficial ) loans in Spain or the Paycheck Protection Program (PPP) in the United States. – Government moratorium measures: In this case, the government authorities define a series of requirements, which, in the event that they are met by the beneficiary, involve the granting of moratoriums by the bank on the payment of capital and/or interest on the various credit operations that customers may have contracted. The specific characteristics of these programs vary depending on how they are defined by the national governments of the – Internal/sectoral moratorium measures: This is, broadly speaking, the granting of moratoriums by the bank on the payment of capital and/or interest on the various credit operations that customers may have contracted. In this case, the specific characteristics of these measures, in terms of terms, amounts, etc., vary according to each geography, product or customer segment in order to adapt them as best as possible to the reality of the local market and its regulation, as well as to the needs of the customer and the product contracted. In many cases, the general conditions of application have been agreed on a sectoral basis, for example through the national banking associations. – Other internal measures: This category includes all those measures not included in the previous sections. The Group has helped customers through the various liquidity programmes, government guarantees, moratoriums and others. The details and magnitude of these measures and their main characteristics can be consulted in section "COVID-19 pandemic implications" . Estimation of expected loss In the context described in the previous sections, many regulators and supervisors have highlighted the uncertainties surrounding the economic impacts of the health crisis. This is also evident in the frequent updates of macroeconomic forecasts, with different perspectives and views on the depth and duration of the crisis. Thus, the guidance (including IASB, ESMA, EBA and ECB) does not set a mechanistic approach to estimating expected credit losses under IFRS 9, in order to prevent this variability in economic conditions from translating into undesired volatility in results, with its potential pro-cyclical effects on the economy. Thus, the Group analyses losses under IFRS 9 on the basis of three types of elements: 1. Continuous monitoring of customers Monitoring the credit quality of customers may be more complex in the current circumstances, in the absence of certain contractual payments on transactions subject to a moratorium. To this end, and in addition to the application of internal customer monitoring policies, all available information should be used. The availability of information and its relevance is different in the various portfolios of the different countries in which the Group operates, but it may include, but is not limited to the following: – The payment of interest in the case of principal-only shortfalls. – The payment of other operations of the same client in the institution (not subject to moratorium). – Information on payment of loans in other entities (through credit bureaus). – Customer financial information: average balances in current accounts, availability/use of limits, etc. – Available behavioural elements (variables that feed the behavioural scores, etc.) – Information gathered from customer contacts (surveys, calls, questionnaires, etc.). This may include: customers who have taken up furlough programs, direct government aid, etc. 2. Forward-looking vision As reflected by the IASB, macroeconomic uncertainty makes the usual application of IFRS9 expected loss calculation models difficult but does not exempt the incorporation of the prospective feature of the standard. To this end, the European Central Bank has recommended the use of a stable, long-term view (long-run) of the macroeconomic forecasts, which takes into account in the assessment the multiple support measures explained above. Santander Group uses macroeconomic scenarios in its strategic and budgetary processes. For the purposes of estimating provisions under IFRS9, in accordance with the regulatory recommendations, the long-run view consistent with these scenarios was used. This long-run vision is generated through a stable long-term perspective, reflecting the structural impairment caused by the pandemic. For this propuse, the movement when the macro, represented by the GDP, recovers its average trend is analysed for each geography, taking into account seasonal factors applicable to each economy. 3. Additional elements Additional elements will be required when necessary because they have not been captured under the two previous elements. This includes, among others, the analysis of sectors most affected by the pandemic if their impacts are not sufficiently captured by the macroeconomic scenarios. Also collective analysis techniques, when the potential impairment in a group of clients cannot be identified individually. With the elements indicated above, the Group evaluates in each of the geographical areas the evolution of the credit quality of its customers, for the purposes of their classification in the Group's financial statements. In terms of classification, the Group has generally maintained the criteria and thresholds for classification during the pandemic, incorporating the regulatory interpretations of the effect of moratoria on classification (in particular, the European Banking Authority's 'Guidelines on legislative and non-legislative moratoria on loan repayments applied in COVID-19 crisis'). In this way, moratoriums that meet the specifications of these guidelines are not considered as automatic indicators for identifying these contractual changes as forbearances or classifying them in stage 2. However, this does not exempt the rigorous application of IFRS9 in the monitoring of costumer credit quality and, using individual or collective analysis techniques, the timely detection of significant increases in risk in certain transactions or groups of transactions. Details of the exposure by stage can be found in Note 5 in this interim condensed consolidated financial statement. This note shows the levels of provisions for the first six months, which amount to EUR 7,027 million, including the provisions to cover the impact to date on expected losses resulting from the pandemic. - Liabilities and commitments for post-employment compensation and other obligations: considering the long-term nature of these commitments, the valuation and main hypothesis-setting criteria are maintained for recording and accounting for post-employment and long-term commitments except for Spain, which has updated its estimates with new mortality tables. On the other hand, eligible assets are quantified at market value and the reference discount rate to determine the value of the obligation continues to be the interest rate of corporate bonds with high credit ratings at the accounting reference date consistent with the duration of the obligations, although the high volatility of the spreads corresponding to said bonds in the last days of the first six months has been taken into account. - Useful life of tangible and intangible assets: based on the type of Group's assets, there have been no significant changes in the estimates of useful life made at the end of 2019 due to COVID-19. - Goodwill: The accounting standard (IAS 36) requires that a cash‑generating unit (“CGU”) to which goodwill has been allocated is tested for impairment annually, and whenever there is an indication that the goodwill may be impaired. The Group’s impairment test in respect of goodwill allocated to each CGU is performed annually. Nevertheless, a review for indicators of impairment is undertaken at each quarter-end. Having considered the reasons explained below, an interim impairment test has been performed at 30 June 2020 for all certain CGUs. The standard establishes a minimum of indicators in assessing whether there is any indication, so even though there is still high uncertainty about how the crisis is going to impact the economies of some of our subsidiaries, the Group considers the circumstances described below as indications of impairment: • Current changes in the economic environment where a decrease of the GDP is expected in most countries and its recovery will take 2 or 3 years. The evolution forecasted by the different national and international organisms for 2020 magnitudes such as GDP, unemployment rate, credit portfolios growth, etc. are negative and the recovery of these economies, will be less steep and at a slower pace than its fall. • The uncertainty in the macroeconomic situation also causes higher expected returns, and market premiums increase significantly. As a result of the higher cost of capital, the discount rates applied to the cash flows are higher (rates reflect the risk associated to the current environment), which result in a lower value in use. • Additionally, the Group is already observing budget deviations in some of the subsidiaries due to the current macroeconomic outlook, which also negatively affect the future cash flows. Considering these trigger events, as of 30 June 2020 the Group has performed its impairment test. In relation with goodwill assessment (i.e. a potential reduction in its recoverable value to below its carrying amount), during the first six months of 2020 the Group recognised goodwill impairment losses amounting to EUR 10,100 million under the heading Impairment on non-financial assets, net - Intangible assets of the condensed consolidated income statement (see Note 8.a). - Provisions and contingent liabilities: the Group's management, after its analysis, has concluded that there have been no significant changes in the estimates made at the end of the 2019 fiscal year in relation to the probability of the obligations that the Group has to meet at 30 June 2020 due to the situation produced to date by COVID-19. - Market risk: the pressures observed in the financial markets during the first semester of 2020 did not have a significant impact in terms of valuation, impairment or allocation of levels for the Group's portfolios, considering, the typology of the Group's products, the low complexity of the portfolios, the decrease in volatility and credit spreads in the second quarter and the observability of the price sources used. There is currently no significant reduction in observables price from sources used for the valuation of financial instruments, although there is still some widening of the price ranges and some dispersion among the various contributors. Therefore, it has meant that no significant worsening of the observable conditions has been detected in the inputs used for the valuation of portfolio financial instruments, nor less access to price contributors and real market operations. Consequently, considering the composition of the Group's portfolios, the impact on the fair value hierarchy has been reduced and most markets and terms have maintained their classifications according to our observability and significance criteria. Given the low market complexity as a general rule of our portfolios, and despite certain increases in valuation adjustments to adequately reflect their fair value in a still volatile environment, there have been no significant reclassifications between levels. The Group continues to monitor the evolution of the markets, their liquidity and the observability conditions of the valuation inputs in order to apply the criteria established in the Group for the levelling of assets and liabilities measured at fair value. The risk levels measured in terms of VaR for all Group's units are at historically low levels. During the first quarter of the year, and despite a general reduction in positions in a context of high volatility, there was a certain one-off increase in VaR as a result of the use of the Weighted VaR methodology, which assigns greater weight to the most recent market scenarios. However, the return to normal market conditions in recent months and the maintenance of reduced positions in most trading portfolios has enabled that at the end of the second quarter risk exposure is at historically low levels of approximately EUR 10 million (VaR 1d 99%). - Deferred tax assets: the Group has reassessed the ability to generate future taxable income in relation to the recoverability of deferred tax assets recorded in the main Group companies. Management considers that the recovery period of these assets would not be affected and that it is not necessary to make adjustments to the deferred tax assets recognised in the Group on the basis of the results of the analyses performed, except in Spain, where the Group considers that the changes in the key assumptions on which the projected results of its tax group are based, arising from the impact of COVID-19 according to the circumstances described in the previous section related to goodwill, have resulted in the recognition of an impairment of EUR 2,500 million of deferred tax assets under tax income in the income statement, maintaining a maximum 15 year period of recoverability of the deferred tax assets recognised at 30 June 2020. During the first six months ended 30 June 2020, there have been no additional significant changes in the estimates made at the end of 2019, other than those indicated in this interim financial information.
Contingent assets and liabilities	Contingent assets and liabilitiesNote 2.o to the Group's consolidated annual accounts for the year ended 31 December 2019 includes information on the contingent assets and liabilities at that date.

(**) Includes mainly short-term loans and reverse repurchase agreements with corporate customers (mainly brokerage and investment companies). (***) Includes credit risk derivatives with a negative net fair value of EU R 0 and EUR 6 million recognised in the interim condensed consolidated balance sheet 30 June 2020 and 31 December 2019. These assets and liabilities are measured using the Standard Gaussian Copula Model. (****) Includes residential mortgages to financial institutions in the United Kingdom (which are regulated and partly financed by the Government). The fair value of these loans has been obtained using observable market variables, including current market transactions of similar amount and guarantees provided by the UK Housing Association. Given that the Government is involved in these entities, credit risk spreads have remained stable and homogeneous in this sector. The results arising from the valuation model are contrasted against current market transactions.
Schedule of effect on fair value of financial instruments classified as Level 3 of a reasonable change in the assumptions used in the valuation	The table below shows the effect, at 30 June 2020, on the fair value of the main financial instruments classified as Level 3 of a reasonable change in the assumptions used in the valuation. This effect was determined by applying the probable valuation ranges of the main unobservable inputs detailed in the following table: Portfolio/Instrument Valuation technique Main unobservable inputs Range Weighted average Impacts (in million euros) (Level 3) Unfavourable scenario Favorable scenario Financial assets held for trading ( assets) Trading derivatives Present Value Method Curves on TAB indixes(*) (a) (a) (0.2) 0.2 Present Value model, modified Black-Scholes HPI forward growth rate 0%-5% 2.53% (22.8) 22.2 HPI spot n/a 427.73 (**) (8.3) 8.3 Caps/Floors Black Model No interest rate curve observable in the market.

(**) There are national and regional HPI indices. The HPI spot value is the weighted average of the indices that correspond to the positions of each portfolio. The impact reported is a change of 10%. (***) Theoretical average value of the parameter. The change arising on a favourable scenario is from 0.0001 to 0.03. An unfavourable scenario is not considered as there is insufficient margin for an adverse change from the current parameter level. (a) The exercise was conducted for the unobservable inputs described in the “main unobservable inputs” column under probable scenarios. The range and weighted average value used are not shown because the aforementioned exercise was conducted jointly for various inputs or variants thereof (e.g. the TAB input comprises vector-time curves, for which there are also nominal yield curves and inflation-indexed yield curves), and it was not possible to break down the results separately by type of input. In the case of the TAB curve the gain or loss is reported for changes of +/-100b.p. for the total sensitivity to this index in CLP and CLF. The same is applicable to the MXN interest rates. (b) The Group calculates the potential impact on the measurement of each instrument on a joint basis, regardless of whether the individual value is positive (assets) or negative (liabilities), and discloses the joint effect associated with the related instruments classified on the asset side of the consolidated balance sheet. * Note: Null impacts in Quanto options arise because the position is completely covered back.to-back. Null impacts on Interest Rate Swaps (Swaps Lock In) arise because the prepaid risk is fully covered.
