Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation, and Significant Accounting Policies and Practices	Description of Business, Basis of Presentation, and Accounting Policies The Company is the holding company for SC Illinois, and its subsidiaries, a specialized consumer finance company focused on vehicle finance and third-party servicing and delivering service to dealers and customers across the full credit spectrum. The Company’s primary business is the indirect origination and servicing of retail installment contracts and leases, principally, through manufacturer-franchised dealers in connection with their sale of new and used vehicles to retail consumers. Additionally, the Company sells consumer retail installment contracts through flow agreements and, when market conditions are favorable, it accesses the ABS market through securitizations of consumer retail installment contracts. SAF is our primary vehicle financing brand, and is available as a finance option for automotive dealers across the United States. Since May 2013, under the Chrysler Agreement with FCA, the Company has operated as FCA’s preferred provider for consumer loans, leases and dealer loans and provides services to FCA customers and dealers under the CCAP brand. These products and services include consumer retail installment contracts and leases, as well as dealer loans for inventory, construction, real estate, working capital and revolving lines of credit. In 2019, the Company entered into an Amendment to the Chrysler Agreement with FCA, which modified that Agreement to, among other things, adjust certain performance metrics, exclusivity commitments and payment provisions. The Company also originates vehicle loans through a web-based direct lending program, purchases vehicle retail installment contracts from other lenders, and services automobile and recreational and marine vehicle portfolios for other lenders. Additionally, the Company has other relationships through which it provides other consumer finance products. As of September 30, 2020, the Company was owned approximately 80.2% by SHUSA, a subsidiary of Santander, and approximately 19.8% by other shareholders. The Company is taking numerous proactive steps to mitigate the negative financial and operational impacts of COVID-19. Business contingency plans have been implemented and will continue to be adjusted in response to the evolving global situation. Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries, including certain Trust that are considered VIEs. The Company also consolidates other VIEs for which it is deemed to be the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying condensed consolidated financial statements as of September 30, 2020 and December 31, 2019, and for the three and nine months ended September 30, 2020 and 2019, have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these financial statements contain all adjustments, consisting of normal and recurring adjustments, necessary for the fair statement of the financial position, results of operations and cash flows for the periods indicated and contain adequate disclosure for the fair statement of this interim financial information. Results of operations for the periods presented herein are not necessarily indicative of results of operations for the entire year. These financial statements should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2019. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates and those differences may be material. The most significant estimates include the determination of credit loss allowance, accretion of discounts and subvention, impairment, fair value measurements, expected end-of-term lease residual values, values of repossessed assets, and income taxes. These estimates, although based on actual historical trends and modeling, may show significant variances over time. Business Segment Information The Company has one reportable segment, Consumer Finance, which includes the Company’s vehicle financial products and services, including retail installment contracts, vehicle leases, and Dealer Loans, as well as financial products and services related to recreational vehicles and marine vehicles. It also includes the Company’s personal loan and point-of-sale financing operations. Recently Adopted Accounting Standards Since January 1, 2020, the Company adopted the following FASB ASUs: • Financial Instruments - Credit Losses (Topic 326) • In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides temporary optional expedients to reduce the costs and complexity associated with the high volume of contractual modifications expected in the transition away from LIBOR as the benchmark rate in contracts and hedges. These optional expedients allow entities to negate many of the accounting impacts of modifying contracts and hedging relationships necessitated by reference rate reform, allowing them to generally maintain the accounting as if a change had not occurred. The Company adopted this standard during the three months ended March 31, 2020, and will elect the practical expedients relative to the Company’s contracts and hedging relationships modified as a result of reference rate reform through December 31, 2022. These practical expedients did not have a material impact on the Company’s business, financial position, results of operations, or disclosures. • In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general tax accounting principles and simplifying other specific tax scenarios. The Company early adopted this update as of January 1, 2020, and it did not have any material impact to the Company’s business, financial position, results of operations, or disclosures. The adoption of the following ASUs did not have a material impact on the Company’s business, financial position or results of operations. • ASU 2018-17, Consolidation (Topic 10): Targeted Improvements to Related Party Guidance for Variable Interest Entities • ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement Accounting Policies There have been no material changes (except as disclosed below) in the Company's accounting policies from those disclosed in Part II, Item 8 - Financial Statements and Supplementary Data in the 2019 Annual Report on Form 10-K. The change in the following policy is as a result of the Company's adoption of CECL standard, on January 1, 2020. • Investment securities Debt securities expected to be held for an indefinite period of time are classified as AFS and recorded on the balance sheet at fair value. If the fair value of an AFS debt security declines below its amortized cost basis and the Company does not have the intention or requirement to sell the security before it recovers its amortized cost basis, declines due to credit factors will be recorded in earnings through the ACL for debt securities, and declines due to non-credit factors will be recorded in AOCI, net of taxes. Subsequent to recognition of a credit loss, improvements to the expectation of collectability will be reversed through the ACL for debt securities. If the Company has the intention or requirement to sell the security, the Company will record its fair value changes in earnings as a direct write down to the security. Increases in fair value above amortized cost basis are recorded in AOCI, net of taxes. The Company conducts an impairment assessment quarterly on all AFS securities with a fair value that is less than their amortized cost basis to determine whether the loss is due to credit factors. Securities for which management expects risk of nonpayment of the amortized cost basis is zero, do not have a reserve. The Company has a zero loss expectation when the securities are issued or guaranteed by certain US government entities, because these entities have a long history of no defaults and the highest credit ratings issued by rating agencies. In the event of a credit loss, the credit component of the impairment is recognized within non-interest income as a separate line item, and by the recording of a valuation reserve. The non-credit component is recorded within AOCI. • Purchased Credit Deteriorated or PCD loans Loans that the Company deems at acquisition to have more than insignificant deterioration in credit quality since origination (i.e., Purchased Credit Deteriorated or PCD loans) require the recognition of an allowance for credit losses at purchase. The allowance for credit losses is added to the purchase price at the date of acquisition to determine the initial amortized cost basis of the PCD loan. The allowance for credit losses is calculated using the same methodology as originated loans, as described below. Alternatively, the Company can elect the fair value option at the time of purchase for any financial asset. Under the FVO, loans are recorded at fair value with changes in value recognized immediately in income. There is no ACL for loans under an FVO. • Credit Loss Expense and Allowance for Credit losses General Credit loss expenses are charged to operations in amounts sufficient to maintain the ACL at levels considered adequate to cover expected credit losses in the Company’s retail installment contracts. The allowance for expected credit losses on retail installment contracts is measured based on a lifetime expected loss model, which means that it is not necessary for a loss event to occur before a credit loss is recognized. Management’s estimate of expected credit losses is based on an evaluation of relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the future collectability of the reported amounts. Management's evaluation takes into consideration the risks in the portfolio, past loss experience, specific loans with loss potential, geographic and industry concentrations, delinquency trends, economic forecasts and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the ACL may be necessary if conditions differ substantially from the assumptions used in making the evaluations. The Company measures expected losses of all components on an amortized cost basis. For all loans except TDRs, the Company has elected to exclude accrued interest receivable balances from the measurement of expected credit losses because it applies a nonaccrual policy that results in the timely write off of uncollectible accrued interest. For loans on nonaccrual status, interest income is recognized on a cash basis, and the accrual of interest is resumed and reinstated if a delinquent account subsequently becomes 60 days or less past due. Methodology The Company uses several methodologies for the measurement of ACL. The ACL is made up of a quantitative and a qualitative component. To determine the quantitative component, the Company generally uses a DCF approach for determining ACL for TDRs and other individually assessed loans, and a non-DCF approach for other loans. Expected credit losses are estimated on an individual basis only if the individual asset or exposure does not share similar risk attributes with other financial assets or exposures, including when an asset is treated as a collateral dependent asset. The ACL estimate includes significant assumptions including the reasonable and supportable economic forecast period, which considers the availability of forward-looking scenarios and their respective time horizons, as well as the reversion method to historical losses. This method results in a single, quantitatively consistent credit model across the entire projection period as the macroeconomic effects in the historical data are controlled for the estimate of the long-run loss level. Models The Company uses a statistical methodology based on an ECL approach that focuses on forecasting the ECL components (i.e., probability of default, payoff, loss given default and exposure at default) on a loan level basis to estimate the expected future life time losses. The individual loan balances used in the models are measured on an amortized cost basis. • In calculating the probability of default and payoff, the Company developed model forecasts, which consider variables such as delinquency status, loan tenor and other credit quality indicators. • The loss given default component forecasts the extent of losses given that a default has occurred and considers variables such as collateral, loan-to-value and other credit quality indicators. • The exposure at default component captures the effects of expected partial prepayments and underpayments that are expected to occur during the forecast period and considers variable such as loan-to-value, collateral and other credit quality indicators. The above ECL components are used to compute an ACL based on the weighted average of the results of the macroeconomic scenarios. The weighting of these scenarios is governed and approved quarterly by management through established committee governance. These ECL components are inputs to both the Company’s DCF approach for TDR and individually assessed loans and non-DCF approach for other loans. When using a non-DCF method to measure the ACL, the Company measures ECL over the asset’s contractual term, adjusted for (a) expected prepayments; (b) expected extensions associated with assets for which management has a reasonable expectation at the reporting date that it will execute a TDR with the borrower; and (c) expected extensions or renewal options (excluding those that are accounted for as derivatives) included in the original or modified contract at the reporting date that are not unconditionally cancellable by the entity. DCF approaches A DCF method measures expected credit losses by forecasting expected future principal and interest cash flows and discounting them using the financial asset’s EIR. The ACL reflects the difference between the amortized cost basis (including accrued interest) and the present value of the expected cash flows. When using a DCF method to measure the ACL, the period of exposure is determined as a function of the Company’s expectations of the timing of principal and interest payments. The Company considers estimated prepayments in the future principal and interest cash flows when utilizing a DCF Method. The Company generally uses a DCF approach for TDRs. Collateral - Dependent Assets A loan is considered a Collateral Dependent Financial Asset when (a) the Company determines foreclosure is probable or (b) the borrower is experiencing financial difficulty and the Company expects repayment to be provided substantially through the operation or sale of the collateral. For all collateral dependent loans such as certain bankruptcy modifications, the Company measures the ACL as the difference between the loan’s amortized cost basis and the fair value of the underlying collateral as of the reporting date, adjusted for expected costs to sell. If repayment or satisfaction of the loan is dependent only on the operation, rather than the sale, of the collateral, the measure of credit losses does not incorporate estimated costs to sell. The collateral dependent loan is written down (i.e. charged off) to the fair value of the collateral adjusted for costs to sell (if repayment from sale is expected.) Any subsequent increase or decrease in the collateral’s fair value less cost to sell is recognized as an adjustment to the related loan’s ACL. Negative allowance Negative allowance is defined as the amount of future recovery expected for accounts that have already been charged-off. The Company performs an analysis of the actual historical recovery values to determine the pattern of recovery and expected rate of recovery over a given historic period, and uses the results of this analysis to determine negative allowance. Negative allowance reduces the ACL. Qualitative Reserve Regardless of the extent of the Company's analysis of customer performance, portfolio evaluations, trends or risk management processes established, a level of imprecision will always exist due to the judgmental nature of loan portfolio and/or individual loan evaluations. The Company maintains a qualitative reserve as a component of the ACL to recognize the existence of these exposures. Imprecisions include loss factors inherent in the loan portfolio that may not have been discreetly contemplated in deriving the quantitative component of the allowance, as well as potential variability in estimates. The qualitative adjustment is also established in consideration of several factors such as the interpretation of economic trends, changes in the nature and volume of our loan portfolio, trends in delinquency and collateral values, and concentration risks. This analysis is conducted at least quarterly, and the Company revises the qualitative component of the allowance when necessary in order to address improving or deteriorating credit quality trends or specific risks associated with loan pool classification, not otherwise captured in the quantitative models. Governance A comprehensive analysis of the ACL is performed by the Company on a quarterly basis. Management regularly monitors the condition of borrowers and assesses both internal and external factors in determining whether any relationships have deteriorated considering factors such as historical loss experience, trends in delinquency, changes in risk composition and underwriting standards, experience and ability of staff and regional and national economic conditions, trends and forecasts. Risk factors are continuously reviewed and revised by management when conditions warrant. The Company's reserves are principally based on various models subject to the Company's model risk management framework. New models are approved by the SHUSA's Model Risk Management Committee. Models, inputs and documentation are further reviewed and validated at least annually, and the Company completes a detailed variance analysis of historical model projections against actual observed results on a quarterly basis. Required actions resulting from the Company's analysis, if necessary, are governed by its ACL Committee. Reserve levels are collectively reviewed for adequacy and approved quarterly by Board-level committees. Changes in the assumptions used in these estimates could have a direct material impact on the credit loss expense in the Consolidated Statements of Operations and in the allowance for credit losses. The loan portfolio represents the largest asset on the Consolidated Balance Sheets. The Company’s models incorporate a variety of assumptions based on historical experience, current conditions and forecasts. Management also applies its judgement in evaluating the appropriateness of the allowance. Material change to the ACL might be necessary if prevailing conditions differ materially from the assumptions and estimates utilized in calculating the ACL. Recently Issued Accounting Standards Not Yet Adopted There are no recently issued GAAP accounting developments that we expect will have a material impact on the Company's business, financial position, results of operations, or disclosures upon adoption.

Most of the Company’s retail installment contracts held for investment are pledged against warehouse lines or securitization bonds (Note 7). Most of the borrowers on the Company’s retail installment contracts held for investment are retail consumers; however, $823,955 and $741,592 of the unpaid principal balance represented fleet contracts with commercial borrowers as of September 30, 2020 and December 31, 2019, respectively. During the nine months ended September 30, 2020 and 2019, the Company originated (including through the SBNA originations program) $11,145,890 and $9,514,939, respectively, in CCAP loans which represented 61% and 56%, respectively, of the total retail installment contract originations (including the SBNA originations program). As of September 30, 2020, borrowers on the Company’s retail installment contracts held for investment are located in Texas (16%), Florida (10%), California (8%), Georgia (5%) and other states each individually representing less than 5% of the Company’s total portfolio. Purchased receivables During the three and nine months ended September 30, 2020 and 2019, the Company did not acquire any vehicle loan portfolios from third party lenders.

Credit Loss Allowance and Credi

Credit Loss Allowance and Credit Quality	9 Months Ended
	Sep. 30, 2020
Loans and Leases Receivable Disclosure [Abstract]
Credit Loss Allowance and Credit Quality	Credit Loss Allowance and Credit Quality Credit Loss Allowance During the first quarter of 2020, the Company changed the model used for estimating the ACL on retail installment contracts from incurred loss model to an expected lifetime loss model, as a result of the Company's adoption of the CECL standard on January 1, 2020. The Company maintains an ACL on the retail installment contracts held for investment, which excludes those loans measured at fair value in accordance with applicable accounting standards. The Company maintains an expected ACL for receivables from dealers based on risk ratings and individually evaluates loans for specific impairment as necessary. As of September 30, 2020 and 2019, the ACL for receivables from dealers is comprised entirely of general allowance as none of these receivables have been determined to be individually impaired. The Company estimates losses on the finance lease receivable portfolio based on delinquency status, loss experience to date, future expectation of losses as well as various economic factors. Retail installment contracts The activity in the ACL for the retail installment contracts for the three and nine months ended September 30, 2020 and 2019 was as follows: Three Months Ended September 30, 2020 Three Months Ended September 30, 2019 Retail Installment Contracts Retail Installment Contracts Non-TDR TDR Non-TDR TDR Balance — beginning of period $ 4,818,187 $ 1,037,628 $ 1,961,893 $ 1,156,303 Credit loss expense (a) 24,841 314,075 484,626 102,494 Charge-offs (b) (334,938) (200,352) (962,573) (381,490) Recoveries 392,042 97,171 567,846 183,305 Balance — end of period $ 4,900,132 $ 1,248,522 $ 2,051,792 $ 1,060,612 Nine Months Ended September 30, 2020 Nine Months Ended September 30, 2019 Retail Installment Contracts Retail Installment Contracts Non-TDR TDR Non-TDR TDR Balance — beginning of period $ 2,123,878 $ 914,718 $ 1,819,360 $ 1,416,743 Day 1 - Adjustment to allowance for adoption of CECL standard 2,030,473 71,833 — — Credit loss expense (a) 1,526,545 581,344 1,279,931 266,913 Charge-offs (b) (1,955,706) (617,536) (2,685,931) (1,217,650) Recoveries 1,174,942 298,163 1,638,432 594,606 Balance — end of period $ 4,900,132 $ 1,248,522 $ 2,051,792 $ 1,060,612 (a) Excluded from the credit loss expense is $13 million and $52 million related to retail installment contracts sold in an off-balance sheet securitization during the three and nine months ended September 30, 2020, respectively. In addition, credit loss expense includes a net of $72 million and $60 million in the credit loss expense related to retail installment contracts transferred to held for sale and returned to held for investment during the three and nine months ended September 30, 2020, respectively. Furthermore, credit loss expense includes $0 million and $20 million related to retail installment contracts transferred to held for sale during the three and nine months ended September 30, 2019, respectively. (b) Charge-offs for retail installment contracts includes partial write-down of loans to the collateral value less estimated costs to sell, for which a bankruptcy notice was received. There is no additional ACL on these loans. The credit risk in the Company’s loan portfolios is driven by credit and collateral quality, and is affected by borrower-specific and economy-wide factors. In general, there is an inverse relationship between credit quality of loans and projections of impairment losses so that loans with better credit quality require a lower expected loss. The Company manages this risk through its underwriting, pricing strategies, credit policy standards, and servicing guidelines and practices, as well as the application of geographic and other concentration limits. The Company estimates lifetime expected losses based on prospective information as well as account level models based on historical data. Unemployment, HPI, and used vehicle index growth rates, along with loan level characteristics, are the key inputs used in the models for prediction of the likelihood that the borrower will default in the forecasted period (the probability of default). The used vehicle index is also used to estimate the loss in the event of default. The historic volume of loan deferrals provided to customers impacted by COVID-19 has driven positive trends in delinquencies and severity (charge-offs) in the quarter, however, the inclusion of key loan characteristics as inputs to the models (including number of extensions) and management’s evaluation of qualitative factors ensure the allowance is appropriate. The Company has determined the reasonable and supportable period to be three years at which time economic forecasts generally tend to revert to historical averages. The Company utilizes qualitative factors to capture any additional risks that may not be captured in either the economic forecasts or in the historical data, including consideration of the current levels of delinquency, charge-offs and used vehicle prices. The Company generally uses a third-party vendor's consensus baseline macroeconomic scenario for the quantitative estimate and additional positive and negative macroeconomic scenarios to make qualitative adjustment for macroeconomic uncertainty, and may consider adjustments to macroeconomic inputs based on market volatility. The baseline scenario was based on the latest consensus forecasts available which show an improvement in key variables in this quarter, including a sharp decrease in unemployment rates (which are a key driver to losses). The scenarios are periodically updated over a reasonable and supportable time horizon with weightings assigned by management and approved through established committee governance. The Company’s ACL increased $0.3 billion and $3.1 billion for the three and nine months ended September 30, 2020. For the three months ended September 30, 2020, the increase was primarily due to portfolio growth. For the nine months ended September 30, 2020, the primary drivers were a $2.1 billion increase at CECL adoption on January 1, 2020, driven mainly by the addition of lifetime expected credit losses for non-TDR loans, and additional reserves specific to COVID-19 risk. Other portfolios The ACL for the period end and its activity for Dealer Loans, Finance Lease receivable portfolio, and Purchased receivable portfolio-credit deteriorated, for the three and nine months ended September 30, 2020 and 2019, is insignificant. Delinquencies Retail installment contracts and personal amortizing term loans are generally classified as non-performing (or nonaccrual) when they are greater than 60 days past due as to contractual principal or interest payments. Dealer receivables are classified as non-performing when they are greater than 90 days past due. At the time a loan is placed in non-performing (nonaccrual) status, previously accrued and uncollected interest is reversed against interest income. If an account is returned to a performing (accrual) status, the Company returns to accruing interest on the loan. When an account is deferred, the loan is returned to accrual status during the deferral period and accrued interest related to the loan is evaluated for collectability. The Company considers an account delinquent when an obligor fails to pay substantially all (defined as 90%) of the scheduled payment by the due date. In each case, the period of delinquency is based on the number of days payments are contractually past due. A summary of delinquencies as of September 30, 2020, and December 31, 2019 is as follows: September 30, 2020 Finance Receivables Held for Investment Retail Installment Contract Loans Purchased Receivables Portfolios - credit deteriorated Total Percent Amortized cost, 30-59 days past due $ 1,673,713 $ 887 $ 1,674,600 5.0 % Amortized cost over 59 days 817,577 334 817,911 2.4 % Total delinquent balance at amortized cost (a) $ 2,491,290 $ 1,221 $ 2,492,511 7.4 % (a) The amount of accrued interest excluded from the disclosed amortized cost table is $64,970. December 31, 2019 Finance Receivables Held for Investment Retail Installment Contract Loans Purchased Receivables Portfolios - credit impaired Total Percent Principal, 30-59 days past due $ 2,972,495 $ 1,930 $ 2,974,425 9.7 % Delinquent principal over 59 days 1,578,452 1,596 1,580,048 5.1 % Total delinquent principal (a) $ 4,550,947 $ 3,526 $ 4,554,473 14.8 % (a) The table includes balances based on UPB. Difference between amortized cost and UPB was not material. As of September 30, 2020 and December 31, 2019, there were no receivables from dealers that were 30 days or more delinquent. The accrual of interest on revolving personal loans continues until the loan is charged off. The unpaid principal balance on revolving personal loans 90 days past due and still accruing totaled $64,358 and $128,872 as of September 30, 2020 and December 31, 2019, respectively. Non-Accrual Loans for Retail Installment Contracts The amortized cost basis of financial instruments that are either non-accrual with related expected credit loss or non-accrual without related expected credit loss for retail installment contracts is as follows: September 30, 2020 Non-accrual loans Non-accrual loans with no allowance (a) Interest income recognized on nonaccrual loans (YTD) Non-accrual loans as a percent of total amortized cost Non-TDR $ 623,428 $ 141,269 $ 57,275 1.9 % TDR 301,647 46,956 27,128 0.9 % Total non-accrual loans $ 925,075 $ 188,225 $ 84,403 2.8 % (a) These represent loans for which a bankruptcy notice was received, and have been partially write-down to the collateral value less estimated costs to sell. Accordingly, there is no additional ACL on these loans. December 31, 2019 Amount Percent Non-TDR $ 1,099,462 3.6 % TDR 516,119 1.7 % Total nonaccrual principal (a) $ 1,615,581 5.3 % (a) The table includes balances based on UPB. Difference between amortized cost and UPB was not material. Delinquent balances and nonaccrual balances are lower as of September 30, 2020 primarily due to a significant increase in deferrals granted to borrowers impacted by COVID-19.

Commercial Lending — The Company’s risk department performs a credit analysis and classifies certain loans over an internal threshold based on the commercial lending classifications. All the receivables from dealers, as of September 30, 2020 and December 31, 2019 were classified as “Pass.” Troubled Debt Restructurings In certain circumstances, the Company modifies the terms of its finance receivables to troubled borrowers. Modifications may include a temporary reduction in monthly payment, reduction in interest rate, an extension of the maturity date, rescheduling of future cash flows, or a combination thereof. A modification of finance receivable terms is considered a TDR if the Company grants a concession to a borrower for economic or legal reasons related to the debtor’s financial difficulties that would not otherwise have been considered. The purchased receivables portfolio - credit deteriorated, operating and finance leases, and loans held for sale, including personal loans, are excluded from the scope of the applicable guidance. The Company’s TDR balance as of September 30, 2020 and December 31, 2019 primarily consisted of loans that had been deferred or modified to receive a temporary reduction in monthly payment. As of September 30, 2020 and December 31, 2019, there were no receivables from dealers classified as a TDR. A loan that has been classified as a TDR remains so until the loan is liquidated through payoff or charge-off. The recognition of interest income on TDR loans reflects management’s best estimate of the amount that is reasonably assured of collection and is consistent with the estimate of future cash flows used in the impairment measurement. Any accrued but unpaid interest is fully reserved for through the recognition of additional impairment, if not expected to be collected. The table below presents the Company’s amortized cost (including accrued interest) of TDRs as of September 30, 2020 and December 31, 2019: September 30, 2020 December 31, 2019 Retail Installment Contracts (a) Amortized Cost including accrued interest (b) $ 3,843,470 $ 3,828,892 Impairment (1,248,522) (914,718) Amortized cost including accrued interest, net of impairment $ 2,594,948 $ 2,914,174 (a) The December 31, 2019 balances were based on unpaid principal balance. Difference between amortized cost and UPB was not material. (b) As of September 30, 2020, these balances excludes $74.0 million of collateral-dependent bankruptcy TDRs that have been written down by $27.1 million to fair value less cost to sell. As of December 31, 2019, this balance excludes $94.9 million of collateral-dependent bankruptcy TDRs that have been written down by $36.4 million to fair value less cost to sell. A summary of the amortized cost (including accrued interest) of the Company’s delinquent TDRs at September 30, 2020 and December 31, 2019 is as follows: September 30, 2020 December 31, 2019 Retail Installment Contracts (a) 30-59 days past due $ 564,838 $ 927,952 Delinquent balance over 59 days 287,289 521,709 Total delinquent TDRs $ 852,127 $ 1,449,661 (a) The December 31, 2019 balances were based on unpaid principal balance. Difference between amortized cost and UPB was not material. The decrease in total delinquent TDRs is primarily due to the significant increase in deferrals granted to borrowers impacted by COVID-19. The additional risk of these deferrals is captured in the ACL for retail installment contracts for the three and nine months ended September 30, 2020. Average amortized cost (including accrued interest) and interest income recognized on TDR loans are as follows: Three Months Ended Nine Months Ended September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Retail Installment Contracts Retail Installment Contracts Average amortized cost (including accrued interest) $ 3,960,119 $ 4,399,099 $ 3,802,823 $ 4,790,378 Interest income recognized 165,637 188,331 457,642 623,324 The following table summarizes the financial effects, excluding impacts related to credit loss allowance and impairment, of TDRs (including collateral-dependent bankruptcy TDRs) that occurred for the three and nine months ended September 30, 2020 and 2019: Three Months Ended Nine Months Ended September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Retail Installment Contracts Retail Installment Contracts Amortized cost (including accrued interest) before TDR $ 317,455 $ 376,206 $ 1,399,813 $ 1,003,755 Amortized cost (including accrued interest) after TDR 319,027 377,750 1,417,480 1,006,637 Number of contracts (not in thousands) 14,620 21,575 69,786 58,783 A TDR is considered to be in default at charge off. For retail installment contracts, charge off is at the earlier of the date of repossession or 120 days past due and, for revolving personal loans, is generally the month in which the receivable becomes 180 days past due. Loan restructurings accounted for as TDRs within the previous twelve months that subsequently defaulted during the three and nine months ended September 30, 2020 and 2019 are summarized in the following table: Three Months Ended Nine Months Ended September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Retail Installment Contracts Retail Installment Contracts Amortized cost (including accrued interest) in TDRs that subsequently defaulted (a) $ 83,002 $ 83,254 $ 183,871 $ 299,619 Number of contracts (not in thousands) 4,379 5,190 10,467 18,097 (a) For TDR modifications and TDR modifications that subsequently default, the allowance methodology remains unchanged; however, the transition rates of the TDR loans are adjusted to reflect the respective risks.

Operating Leases (SC as Lessee) The Company has entered into various operating leases, primarily for office space. Operating leases are included within other assets as operating lease ROU assets and other liabilities within our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Most of our real estate leases include one or more options to renew, with renewal terms that can extend the lease term from one year to 15 years or more. The exercise of lease renewal options is at our sole discretion. The Company does not include any of the renewal options in the lease term as it is not reasonably certain that these options will be exercised. Supplemental information relating to these operating leases is as follows: September 30, 2020 Operating leases-right of use assets $ 49,443 Other liabilities 68,545 Weighted average lease term 5.6 Weighted average discount rate 3.4 % Lease expense i ncurred totaled $3,479 and $3,402 for the three months ended September 30, 2020 and 2019, respectively, and $10,586 and $10,316 for the nine months ended September 30, 2020 and 2019, and is included within “other operating costs” in the income statement. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a strai ght-line basis over the lease term. Cash paid for amounts included in the measurement of operating lease liabilities was $12,947 d uring the nine months ended September 30, 2020. The maturity of lease liabilities at September 30, 2020 are as follows: September 30, 2020 2020 $ 4,175 2021 13,343 2022 12,639 2023 12,762 2024 12,701 Thereafter 19,691 Total $ 75,311 Less: Interest (6,766) Present value of lease liabilities $ 68,545 Available-for-sale and Held-to-maturity debt securities Debt securities expected to be held for an indefinite period of time are classified as AFS and are carried at fair value, with temporary unrealized gains and losses reported as a component of accumulated other comprehensive income within stockholder's equity, net of estimated income taxes. All of these securities are used to satisfy collateral requirements for our derivative financial instruments. Debt securities that the Company has the positive intent and ability to hold until maturity are classified as HTM securities. HTM securities are reported at cost and adjusted for payments, charge-offs, amortization of premium and accretion of discount. Realized gains and losses on sales of investment securities are recognized on the trade date and are determined using specific identification method and are included in earnings within Investment gain (losses) on sale of securities. Unamortized premiums and discounts are recognized in interest income over the estimated life of the security using the interest method.

Variable Interest Entity Disclosure [Abstract]
Variable Interest Entities	Variable Interest Entities The Company transfers retail installment contracts and vehicle leases into newly formed Trusts that then issue one or more classes of notes payable backed by the collateral. The Company’s continuing involvement with these Trusts is in the form of servicing the assets and, generally, through holding residual interests in the Trusts. The Trusts are considered VIEs under GAAP and the Company may or may not consolidate these VIEs on the condensed consolidated balance sheets. For further description of the Company’s securitization activities, involvement with VIEs and accounting policies regarding consolidation of VIEs, see Part II, Item 8 - Financial Statements and Supplementary Data (Note 7) in the 2019 Annual Report on Form 10-K. On-balance sheet variable interest entities The assets of consolidated VIEs, presented based upon the legal transfer of the underlying assets in order to reflect legal ownership, that can be used only to settle obligations of the consolidated VIE and the liabilities of these entities for which creditors (or beneficial interest holders) do not have recourse to the Company’s general credit were as follows: September 30, 2020 December 31, 2019 Assets Restricted cash $ 1,763,252 $ 1,629,870 Finance receivables held for investment, net 22,711,254 26,532,328 Leased vehicles, net 16,195,376 16,461,982 Various other assets 870,229 625,359 Total assets $ 41,540,111 $ 45,249,539 Liabilities Notes payable $ 31,265,215 $ 34,249,851 Various other liabilities 117,997 188,093 Total liabilities $ 31,383,212 $ 34,437,944 Certain amounts shown above are greater than the amounts shown in the corresponding line items in the accompanying condensed consolidated balance sheets due to intercompany eliminations between the VIEs and other entities consolidated by the Company. For example, for most of its securitizations, the Company retains one or more of the lowest tranches of bonds. Rather than showing investment in bonds as an asset and the associated debt as a liability, these amounts are eliminated in consolidation as required by GAAP. The Company retains servicing rights for receivables transferred to the Trusts and receives a monthly servicing fee on the outstanding principal balance. Supplemental fees, such as late charges, for servicing the receivables are reflected in fees, commissions and other income. As of September 30, 2020 and December 31, 2019, the Company was servicing $27,688,633 and $27,253,573, respectively, of gross retail installment contracts that have been transferred to consolidated Trusts. The remainder of the Company’s retail installment contracts remain unpledged.

The Company also executes private securitizations under Rule 144A of the Securities Act and periodically issues private term amortizing notes, which are structured similarly to securitizations but are acquired by banks and conduits. The Company’s securitiz ations and private issuances are collateralized by vehicle retail installment contracts and loans or leases.

For securitizations, the term takes into consideration the expected execution of the contractual call option, if applicable. Amortization of premium or accretion of discount on notes payable is also included in interest expense using the effective interest method over the estimated remaining life of the notes. Total interest expense on secured structured financings for the three months ended September 30, 2020 and 2019 was $150,734 and $217,544, respectively, and for the nine months ended September 30, 2020 and 2019 was $522,266 and $671,770, respectively .

Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity Share Repurchases During the three months ended March 31, 2020, the Company purchased shares of its common stock through a modified Dutch Auction Tender Offer. In June 2019, the Company announced that the Board had authorized purchases by the Company of up to $1.1 billion , excluding commissions, of its outstanding common stock effective from the third quarter of 2019 through the end of the second quarter of 2020. The Company extended the share repurchase program through the end of the third quarter of 2020. On July 31, 2020, the Company announced that SHUSA’s request for certain exceptions to the Federal Reserve Board’s interim policy (the “Interim Policy”), prohibiting share repurchases and limiting dividends to all CCAR institutions to the average trailing net income, had been approved. Such approval permitted the Board to authorize to continue its share repurchase program through the end of the third quarter of 2020. On August 10, 2020, the Company announced that it had substantially exhausted the amount of shares the Company was permitted to repurchase under the previously disclosed exception to the Interim Policy and that the Company expected to repurchase an immaterial number of shares remaining under the exception approval. On September 30, 2020, the Federal Reserve Board extended the Interim Policy through the fourth quarter of 2020. As a result, SC does not currently expect to declare or pay a dividend in the fourth quarter of 2020.

On September 30, 2020, the FRB extended the interim policy prohibiting share repurchases and limiting dividends to all CCAR banks to the average trailing net income. Based on SHUSA’s expected average trailing four quarters of net income, SC is prohibited from paying a dividend in the fourth quarter of 2020. Although SC’s standalone income is sufficient to declare and a pay a dividend, SC is consolidated into SHUSA’s capital plan and therefore is subject to the FRB’s interim policy that utilizes SHUSA’s average trailing income to determine the cap on common stock dividends. SC does not currently expect to declare or pay a dividend in the fourth quarter of 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company uses derivative financial instruments such as interest rate swaps, interest rate caps and the corresponding options written in order to offset the interest rate caps to manage the Company’s exposure to changing interest rates. The Company uses both derivatives that qualify for hedge accounting treatment and economic hedges. The underlying notional amounts of these derivative financial instruments at September 30, 2020 and December 31, 2019, are as follows: September 30, 2020 December 31, 2019 Notional Asset Liability Notional Asset Liability Interest rate swap agreements designated as cash flow hedges $ 2,750,000 $ — $ (79,350) $ 2,650,000 $ 2,807 $ (39,128) Interest rate swap agreements not designated as hedges 250,000 — (14,393) 1,281,000 — (10,267) Interest rate cap agreements 11,117,779 5,999 — 9,379,720 62,552 — Options for interest rate cap agreements 11,117,779 — (5,999) 9,379,720 — (62,552) The aggregate fair value of the interest rate swap agreements was included on the Company’s condensed consolidated balance sheets in other assets and other liabilities, as appropriate. The interest rate cap agreements were included in other assets and the related options in other liabilities on the Company’s condensed consolidated balance sheets. See Note 10 - “ Fair Value of Financial Instruments ” in the accompanying condensed financial statements for additional disclosure of fair value and balance sheet location of the Company’s derivative financial instruments. The Company enters into legally enforceable master netting agreements that reduce risk by permitting netting of transactions, such as derivatives and collateral posting, with the same counterparty on the occurrence of certain events. A master netting agreement allows two counterparties the ability to net-settle amounts under all contracts, including any related collateral posted, through a single payment. The right to offset and certain terms regarding the collateral process, such as valuation, credit events and settlement, are contained in ISDA master agreements. The Company has elected to present derivative balances on a gross basis even if the derivative is subject to a legally enforceable master netting (ISDA) agreement. Collateral that is received or pledged for these transactions is disclosed within the “Gross Amounts Not Offset in the condensed Consolidated Balance Sheet” section of the tables below. Information on the offsetting of derivative assets and derivative liabilities due to the right of offset was as follows, as of September 30, 2020 and December 31, 2019: Gross Amounts Not Offset in the Assets Presented Collateral Net September 30, 2020 Interest rate caps - Santander and affiliates $ 815 $ — $ 815 Interest rate caps - third party 5,184 (5,184) — Total derivatives subject to a master netting arrangement or similar arrangement 5,999 (5,184) 815 Total derivatives not subject to a master netting arrangement or similar arrangement — — — Total derivative assets $ 5,999 $ (5,184) $ 815 Total financial assets $ 5,999 $ (5,184) $ 815 December 31, 2019 Interest rate swaps - third party (b) $ 2,807 $ (540) $ 2,267 Interest rate caps - Santander and affiliates 25,330 (14,930) 10,400 Interest rate caps - third party 37,222 (26,199) 11,023 Total derivatives subject to a master netting arrangement or similar arrangement 65,359 (41,669) 23,690 Total derivatives not subject to a master netting arrangement or similar arrangement — — — Total derivative assets $ 65,359 $ (41,669) $ 23,690 Total financial assets $ 65,359 $ (41,669) $ 23,690 (a) Collateral received includes cash, cash equivalents, initial margin and other financial instruments. Cash collateral received is reported in Other liabilities in the consolidated balance sheet. Financial instruments that are pledged to the Company are not reflected in the accompanying balance sheet since the Company does not control or have the ability of rehypothecation of these instruments. In certain instances, the counter party is over-collateralized since the actual amount of collateral received exceeds the associated financial asset.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended
	Sep. 30, 2020
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value measurement requires that valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs and also establishes a fair value hierarchy that categorizes the inputs to valuation techniques used to measure fair value into three levels as follows: Level 1 inputs are quoted prices in active markets for identical assets or liabilities that can be accessed as of the measurement date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3 inputs are those that are unobservable or not readily observable for the asset or liability and are used to measure fair value to the extent relevant observable inputs are not available. Financial Instruments Measured At Fair Value On A Recurring Basis The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis at September 30, 2020 and December 31, 2019, and the level within the fair value hierarchy: Level 1 Level 2 Level 3 Balance at September 30, 2020 Level 1 Level 2 Level 3 Balance at December 31, 2019 Other assets: Trading interest rate caps (a) $ — $ 5,999 $ — $ 5,999 $ — $ 62,552 $ — $ 62,552 Cash flow hedging interest rate swaps (a) — — — $ — — 2,807 — $ 2,807 Available-for-sale-debt securities (b) — 95,666 — $ 95,666 — 92,246 — $ 92,246 Other liabilities: Trading options for interest rate caps (a) — 5,999 — $ 5,999 — 62,552 — $ 62,552 Cash flow hedging interest rate swaps (a) — 79,350 — $ 79,350 — 39,128 — $ 39,128 Trading interest rate swaps (a) — 14,393 — $ 14,393 — 10,267 — $ 10,267 Retail installment contracts (c)(d) — — 8,248 $ 8,248 — 17,634 4,719 $ 22,353 (a) The valuation is determined using widely accepted valuation techniques including a DCF on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurement of its derivatives. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings and guarantees. The Company utilizes the exception in ASC 820-10-35-18D (commonly referred to as the “portfolio exception”) with respect to measuring counterparty credit risk for instruments (Note 9). (b) The Company's AFS debt securities includes U.S. Treasury securities that are valued utilizing observable market quotes. The Company obtains vendor trading platform data (actual prices) from a number of live data sources, including active market makers and interdealer brokers and its securities are therefore, classified as Level 2. (c) For certain retail installment contracts reported in finance receivables held for investment, net, the Company has elected the fair value option. The fair values of the retail installment contracts are estimated using a DCF model are classified as Level 3. As of December 31, 2019, Company had used the most recent purchase price as the fair value for certain loans and hence classified those retail installment contracts as Level 2. Changes in the fair value are recorded in investment gains (losses), net in the condensed consolidated statement of income. (d) The aggregate fair value of retail installment contracts in non-accrual status, as of September 30, 2020 and December 31, 2019, i s $2,031 a nd $9,511, respectively. Level 3 Rollforward for Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents the changes in retail installment contracts held for investment balances classified as Level 3 balances for the three and nine months ended September 30, 2020 and 2019: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 Balance — beginning of year $ 10,585 $ 8,832 $ 4,719 $ 13,509 Additions / issuances — — 2,512 2,079 Transfer from level 2 (a) — — 17,634 — Net collection activities (2,410) (3,176) (16,854) (10,242) Gains recognized in earnings 73 632 237 942 Balance — end of year $ 8,248 $ 6,288 $ 8,248 $ 6,288 (a) The Company transferred retail installment contracts from Level 2 to Level 3 during the three months ended March 31, 2020 because the fair value for these assets could not be determined by using readily observable inputs at March 31, 2020. There we re no other material transfers in or out of Level 3 during the three and nine months ended September 30, 2020 and three and nine months ended September 30, 2019. Financial Instruments Measured At Fair Value On A Nonrecurring Basis The following table presents the Company’s assets and liabilities that are measured at fair value on a nonrecurring basis at September 30, 2020 and December 31, 2019, respectively: Nine Months Ended September 30, 2020 Year Ended December 31, 2019 Total Lower of cost or fair value expense Total Lower of cost or fair value expense Other assets — vehicles (a) $ 370,678 $ — $ 341,465 $ — Personal loans held for sale (b) 763,292 241,198 1,007,105 408,700 Auto loans impaired due to bankruptcy (c) 188,226 — 200,504 9,106 ( a) The Company estimates the fair value of its vehicles, which are obtained either through repossession or lease termination, using historical auction rates and current market levels of used car prices. (b) The estimated fair value for personal loans held for sale is calculated based on the lower of market participant view and a DCF analysis in which the Company uses significant unobservable inputs on key assumptions. The lower of cost or fair value adjustment for personal loans held for sale includes customer default activity and adjustments related to the net change in the portfolio balance during the reporting period. (c) For loans that are considered collateral-dependent, such as certain bankruptcy loans, impairment is measured based on the fair value of the collateral, less its estimated cost to sell. For the underlying collateral, the estimated fair value is obtained using historical auction rates and current market levels of used car prices. No additional lower of cost or fair value expense was recorded for the nine months ended September 30, 2020. Quantitative Information about Level 3 Fair Value Measurements The following table presents quantitative information about the significant unobservable inputs for assets and liabilities measured at fair value on a recurring and nonrecurring basis at September 30, 2020 and December 31, 2019, respectively: Financial Instruments Fair Value at September 30, 2020 Valuation Technique Unobservable Inputs Range (weighted average) (a) Financial Assets: Retail installment contracts held for investment $ 8,248 Discounted Cash Flow Discount Rate 8%-14% (9%) Default Rate 4%-20% (5%) Prepayment Rate 15%-25% (15%) Loss Severity Rate 50%-60% (56%) Personal loans held for sale (b) $ 763,292 Lower of Market or Income Approach Market Approach Market Participant View 60%-70% Income Approach Discount Rate 20%-30% Default Rate 40%-50% Net Principal & Interest Payment Rate 65%-75% Loss Severity Rate 90%-95% (a) Weighted average was developed by weighting the associated relative unpaid principal balances. (b) The estimated fair value for personal loans held for sale (Bluestem) is calculated based on the lower of market participant view, a DCF analysis in which the Company uses significant unobservable inputs on key assumptions, and also considers the possible outcomes of the Bluestem bankruptcy process. Financial Instruments Fair Value at December 31, 2019 Valuation Technique Unobservable Inputs Range Financial Assets: Retail installment contracts held for investment $ 4,719 Discounted Cash Flow Discount Rate 8%-10% Default Rate 15%-20% Prepayment Rate 6%-8% Loss Severity Rate 50%-60% Personal loans held for sale $ 1,007,105 Lower of Market or Income Approach Market Approach Market Participant View 70%-80% Income Approach Discount Rate 15%-25% Default Rate 30%-40% Net Principal & Interest Payment Rate 70%-85% Loss Severity Rate 90%-95% Financial Instruments Disclosed, But Not Carried, At Fair Value The following tables present the carrying value and estimated fair value of the Company’s financial assets and liabilities disclosed, but not carried, at fair value at September 30, 2020 and December 31, 2019, and the level within the fair value hierarchy: September 30, 2020 December 31, 2019 Carrying Estimated Level 1 Level 2 Level 3 Carrying Estimated Level 1 Level 2 Level 3 Assets: Cash and cash equivalents (a) $ 105,616 $ 105,616 $ 105,616 $ — $ — $ 81,848 $ 81,848 $ 81,848 $ — $ — Finance receivables held for investment, net (b) 27,253,256 29,354,905 — — 29,354,905 27,544,162 28,133,427 — 1,009,358 27,124,069 Restricted cash (a) 2,267,154 2,267,154 2,267,154 — — 2,079,239 2,079,239 2,079,239 — — Investments in debt securities held to maturity (c) 50,381 50,942 — 50,942 — — — — — — Total $ 29,676,407 $ 31,778,617 $ 2,372,770 $ 50,942 $ 29,354,905 $ 29,705,249 $ 30,294,514 $ 2,161,087 $ 1,009,358 $ 27,124,069 Liabilities: Notes Payable: Facilities with third parties (d) $ 2,803,684 $ 2,803,684 $ — $ — $ 2,803,684 $ 5,399,931 $ 5,399,931 $ — $ — $ 5,399,931 Secured structured financings (e) 27,364,089 27,883,027 — 18,638,472 9,244,555 28,141,885 28,360,948 — 18,646,326 9,714,622 Facilities with Santander and related subsidiaries (f) 11,201,574 11,539,861 — — 11,539,861 5,652,325 5,724,675 — — 5,724,675 Total $ 41,369,347 $ 42,226,572 $ — $ 18,638,472 $ 23,588,100 $ 39,194,141 $ 39,485,554 $ — $ 18,646,326 $ 20,839,228 (a) Cash and cash equivalents and restricted cash — The carrying amount of cash and cash equivalents, including restricted cash, is at an approximated fair value as the instruments mature within 90 days or less and bear interest at market rates. (b) Finance receivables held for investment, net — Finance receivables held for investment, net are carried at amortized cost, net of an allowance. These receivables exclude retail installment contracts that are measured at fair value on a recurring and nonrecurring basis. The estimated fair value for the underlying financial instruments is determined as follows: • Retail installment contracts held for investment and purchased receivables - credit deteriorated — As of December 31, 2019 , the Company used the most recent purchase price as the fair value for certain loans and therefore, classified those retail installment contracts as Level 2. The estimated fair value of all finance receivables at September 30, 2020 is estimated using a DCF model, and such receivables are classified as Level 3. • Finance lease receivables — Finance lease receivables are carried at gross investments, net of unearned income and allowance for lease losses. Management believes that the terms of these credit agreements approximate market terms for similar credit agreements. • Receivables from dealers and personal loans held for investment — Receivables from dealers and personal loans held for investment are carried at amortized cost, net of credit loss allowance. Management believes that the terms of these credit agreements approximate market terms for similar credit agreements. (c) Investments in debt securities held to maturity - Investments in debt securities held to maturity are recorded at amortized cost and are priced by third-party pricing vendors. The third-party vendors use a variety of methods when pricing these securities that incorporate relevant observable market data to arrive at an estimate of what a buyer in the marketplace would pay for a security under current market conditions. These investment securities are, therefore, considered Level 2. (d) Notes payable — facilities with third parties — The carrying amount of notes payable related to revolving credit facilities is estimated to approximate fair value. Management believes that the terms of these credit agreements approximate market terms for similar credit agreements as the facilities are subject to short-term floating interest rates that approximate rates available to the Company. (e) Notes payable — secured structured financings — The estimated fair value of notes payable related to secured structured financings is calculated based on market observable prices and spreads for the Company’s publicly traded debt and market observed prices of similar notes issued by the Company, or recent market transactions involving similar debt with similar credit risks, which are considered Level 2 inputs. The estimated fair value of notes payable related to privately issued amortizing notes is calculated based on a combination of credit enhancement review, discounted cash flow analysis and review of market observable spreads for similar liabilities. In conducting this analysis, the Company uses significant unobservable inputs on key assumptions, which are considered Level 3 inputs. (f) Notes payable — facilities with Santander and related subsidiaries — The carrying amount of floating rate notes payable to a related party is estimated to approximate fair value as the facilities are subject to short-term floating interest rates that approximate rates available to the Company. The fair value premium/discount of the fixed rate promissory notes are derived from changes in the Company’s unsecured cost of funds since the time of issuance and weighted average life of these notes.

Investments, Debt and Equity Securities [Abstract]
Investment Losses, Net	Investment Losses, NetWhen the Company sells retail installment contracts, personal loans or leases to unrelated third parties or to VIEs and determines that such sale meets the applicable criteria for sale accounting, the Company recognizes a gain or loss for the difference between the cash proceeds and carrying value of the assets sold. The gain or loss is recorded in investment gains (losses), net. Lower of cost or market adjustments on the amortized cost of finance receivables held for sale are also recorded in investment gains (losses), net. Investment gains (losses), net was comprised of the following for the three and nine months ended September 30, 2020 and 2019: Three Months Ended Nine Months Ended September 30, 2020 September 30, 2019 September 30, 2020 September 30, 2019 Gain (loss) on sale of loans and leases $ (13,669) $ — $ (40,553) $ — Lower of cost or market adjustments (56,598) (87,454) (241,198) (239,166) Other gains, (losses and impairments), net 1,278 1,057 1,754 885 $ (68,989) $ (86,397) $ (279,997) $ (238,281)

Income Taxes	Income Taxes The Company recorded income tax expense of $172,476 (26.0% eff ective tax rate) and $82,156 (26.1% effective tax rate) during the three months ended September 30, 2020 and 2019, respectively. The Company recorded income tax of $137,161 (26.0% effecti ve tax rate) and $283,684 (25.1% effective tax rate) during the nine months ended September 30, 2020 and 2019, respectively. The Company is a party to a tax sharing agreement requiring that the unitary state tax liability among affiliates included in unitary state tax returns be allocated using the hypothetical separate company tax calculation method. The Company had a net receivable from affiliates under the tax sharing agreem ent of $1,003 an d $11,010 at September 30, 2020 and December 31, 2019, respectively, which was included in related party taxes receivable in the condensed consolidated balance sheet. The Company provides U.S. income taxes on earnings of foreign subsidiaries unless the subsidiaries’ earnings are considered indefinitely reinvested outside of the United States. As of September 30, 2020 and December 31, 2019, the Com pany has no earnings that are considered indefinitely reinvested. The Company applies an aggregate portfolio approach whereby disproportionate income tax effects from accumulated other comprehensive income are released only when an entire portfolio (i.e., all related units of account) of a particular type is liquidated, sold or extinguished. Significant judgment is required in evaluating and reserving for uncertain tax positions. Although management believes adequate reserves have been established for all uncertain tax positions, the final outcomes of these matters may differ. Management does not believe the outcome of any uncertain tax position, individually or combined, will have a material effect on the Company’s business, financial position or results of operations. The reserve for uncertain tax positions, as well as associated penalties and interest, is a component of the income tax provision.

Commitments and Contingencies	Commitments and Contingencies The following table summarizes liabilities recorded for commitments and contingencies as of September 30, 2020 and December 31, 2019, all of which are included in accounts payable and accrued expenses in the accompanying condensed consolidated balance sheets: Agreement or Legal Matter Commitment or Contingency September 30, 2020 December 31, 2019 Chrysler Agreement Revenue-sharing and gain/(loss), net-sharing payments $ 50,809 $ 12,132 Agreement with Bank of America Servicer performance fee 1,508 2,503 Agreement with CBP Loss-sharing payments 392 1,429 Other Contingencies Consumer arrangements 25,099 1,991 Legal and regulatory proceedings Aggregate legal and regulatory liabilities 45,047 137,000 Total commitments and contingencies $ 122,855 $ 155,055 Following is a description of the agreements and legal matters pursuant to which the liabilities in the preceding table were recorded. Chrysler Agreement Under terms of the Chrysler Agreement, the Company must make revenue sharing payments to FCA and also must share with FCA when residual gains/(losses) on leased vehicles exceed a specified threshold. The Company had accrued $50,809 and $12,132 at September 30, 2020 and December 31, 2019, respectively, related to these obligations. The Chrysler Agreement also requires that the Company maintain at least $5.0 billion in funding available for Floorplan Loans and $4.5 billion of financing dedicated to FCA retail financing. In turn, FCA must provide designated minimum threshold percentages of its subvention business to the Company. Agreement with Bank of America Until January 2017, the Company had a flow agreement with Bank of America whereby the Company was committed to selling up to $300,000 of eligible loans to the bank each month. The Company retains servicing on all sold loans and may receive or pay a servicer performance payment based on an agreed-upon formula if performance on the sold loans is better or worse, respectively, than expected performance at time of sale. Servicer performance payments are due six years from the cut-off date of each loan sale. The Company had accrued $1,508 and $2,503 at September 30, 2020 and December 31, 2019, respectively, related to this obligation. Agreement with CBP Until May 2017, the Company sold loans to CBP under terms of a flow agreement and predecessor sale agreements. The Company retained servicing on the sold loans and owes CBP a loss-sharing payment capped at 0.5% of the original pool balance if losses exceed a specified threshold, established on a pool-by-pool basis. Loss-sharing payments are due the month in which net losses exceed the established threshold of each loan sale. The Company had accrued $392 and $1,429 at September 30, 2020 and December 31, 2019, respectively, related to the loss-sharing obligation. Other Contingencies The Company is or may be subject to potential liability under various other contingent exposures. The Company had accrued $25,099 and $1,991 at September 30, 2020 and December 31, 2019, respectively, for other miscellaneous contingencies. Legal and regulatory proceedings Periodically, the Company, including its subsidiaries, is and in the future expects to be party to, or otherwise involved in, various claims, disputes, lawsuits, investigations, regulatory matters and other legal matters and proceedings that arise in the ordinary course of business. In view of the inherent difficulty of predicting the outcome of any such claims, disputes, lawsuit, investigations, regulatory matter or legal proceeding, particularly where the claimants seek very large or indeterminate damages or where the matters present novel legal theories or involve a large number of parties, the Company generally cannot predict the eventual outcome of the pending matters, the timing of the ultimate resolution of the matters, or the eventual loss, fines or penalties related to the matter, if any. Accordingly, except as provided below, the company is unable to reasonably estimate a range of its potential exposure, if any, to these claims, disputes, lawsuits, investigations, regulatory matters, and other legal proceedings at this time. Further, it is reasonably possible that actual outcomes or losses may differ materially from the Company’s current assessments and estimates and any adverse resolution of any of these matters against it could materially and adversely affect the Company’s business, financial position, liquidity, and results of operation. In accordance with applicable accounting guidance, the Company establishes an accrued liability for legal and, regulatory proceedings when those matters present material loss contingencies that are both probable and estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. When a loss contingency is not both probable and estimable, the Company does not establish an accrued liability. As a legal or regulatory proceeding develops, the Company, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether the matter presents a material loss contingency that is probable and estimable. If a determination is made during a given quarter that a material loss contingency is probable and estimable, an accrued liability is established during such quarter with respect to such loss contingency and the Company continues to monitor the matter for further developments that could affect the amount of the accrued liability previously established. As of September 30, 2020 and December 31, 2019, the Company accrued aggregate legal and regulatory liabilities of $45 million and $137 million, respectively. Further, the Company estimates the aggregate range of reasonably possible losses for legal and regulatory proceedings, in excess of reserves established, is up to $11.5 million as of September 30, 2020. Set forth below are descriptions of the material lawsuits, regulatory matters and other legal proceedings to which the Company is subject. Securities Class Action and Shareholder Derivative Lawsuits • Deka Lawsuit: The Company is a defendant in a purported securities class action lawsuit (the "Deka Lawsuit") in the United States District Court, Northern District of Texas, captioned Deka Investment GmbH et al. v. Santander Consumer USA Holdings Inc. et al ., No. 3:15-cv-2129-K. The Deka Lawsuit, which was filed in August 26, 2014, was brought against the Company, certain of its current and former directors and executive officers and certain institutions that served as underwriters in the Company’s IPO on behalf of a class consisting of those who purchased or otherwise acquired our securities between January 23, 2014 and June 12, 2014. The complaint alleges, among other things, that our IPO registration statement and prospectus and certain subsequent public disclosures violated federal securities laws by containing misleading statements concerning the Company’s ability to pay dividends and the adequacy of the Company’s compliance systems and oversight. In December 2015, the Company and the individual defendants moved to dismiss the lawsuit, which was denied. In December 2016, the plaintiffs moved to certify the proposed classes.

No. 11614-VCG (the "Feldman Lawsuit"). The Feldman Lawsuit names as defendants certain current and former members of the Board, and names the Company as a nominal defendant. The complaint alleges, among other things, that the current and former director defendants breached their fiduciary duties in connection with overseeing the Company’s nonprime vehicle lending practices, resulting in harm to the Company. The complaint seeks unspecified damages and equitable relief. In December 2015, the Feldman Lawsuit was stayed pending the resolution of the Deka Lawsuit. In September 2016, a shareholder derivative complaint was filed in the Court of Chancery of the State of Delaware, captioned Jackie888, Inc. v. Jason Kulas, et al ., C.A. No. 12775-VCG (the "Jackie888 Lawsuit"). The Jackie888 Lawsuit names as defendants current and former members of the Board, and names the Company as a nominal defendant. The complaint alleges, among other things, that the director defendants breached their fiduciary duties in connection with the Company’s accounting practices and controls. The complaint seeks unspecified damages and equitable relief. In April 2017, the Jackie888 Lawsuit was stayed pending the resolution of the Deka Lawsuit.

In January 2020, the Company executed a Stipulation and Agreement of Settlement, Compromise and Release with the plaintiffs in the consolidated action that, subject to Court approval, fully resolves all of the plaintiffs’ claims in the Feldman Lawsuit and the Jackie888 Lawsuit. The Stipulation provides for the settlement of the consolidated action and, in return, the Company has enacted or will enact and implement certain corporate governance reforms and enhancements. The Settlement Hearing at which the Court would consider the settlement was scheduled for May 27, 2020, but a shareholder filed its notice of intent to object to the settlement and the parties agreed to postpone the Settlement Hearing to a later date.

The stated purpose of the CID is to determine whether the Company has complied with the Fair Credit Reporting Act and related regulations. The Company has responded to these requests within the deadlines specified in the CIDs and has otherwise cooperated with the CFPB with respect to this matter. In February 2020, the Company received a communication from the CFPB inviting the Company to respond to the CFPB’s identified issues in the form of a Notice of Opportunity to Respond and Advise (“NORA”) during which the CFPB identified potential claims it might bring against the Company. • 2017 Written Agreement with the Federal Reserve: In March 2017, the Company and SHUSA entered into a written agreement with the FRBB.

Jim Hood, Attorney General of the State of Mississippi v. Santander Consumer USA Inc., C.A. # G-2017-28. The complaint alleges that the Company engaged in unfair and deceptive business practices to induce Mississippi consumers to apply for loans that they could not afford. The complaint asserts claims under the Mississippi Consumer Protection Act (the MCPA) and seeks unspecified civil penalties, equitable relief and other relief. In March 2017, the Company filed motions to dismiss the lawsuit and the parties are proceeding with discovery. Agreements • Bluestem The Company is party to agreements with Bluestem whereby the Company is committed to purchase certain new advances on personal revolving financings receivables, along with existing balances on accounts with new advances, originated by Bluestem for an initial term ending in April 2020 and renewable through April 2022 at Bluestem’s option. As of September 30, 2020 and December 31, 2019, the total unused credit available to customers was $2.8 billion and $3.0 billion, respectively. In 2020, the Company purchased $0.8 billion of receivables, out of the $3 billion unused credit available to customers as of December 31, 2019. In 2019, the Company purchased $1.2 billion of receivables, out of the $3.1 billion unused credit available to customers as of December 31, 2018. In addition, the Company purchased $151,163 and $137,821 of receivables related to newly opened customer accounts during the nine months ended September 30, 2020 and 2019 respectively. Each customer account generated under the agreements, generally, is approved with a credit limit higher than the amount of the initial purchase with each subsequent purchase automatically approved as long as it does not cause the account to exceed its limit and the customer is in good standing. As of September 30, 2020 and December 31, 2019, the Company was obligated to purchase $13,281 and $10,628, respectively, in receivables that had been originated by Bluestem but not yet purchased by the Company. The Company also is required to make a profit-sharing payment to Bluestem each month if performance exceeds a specified return threshold. The agreement, among other provisions, gives Bluestem the right to repurchase up to 9.99% of the existing portfolio at any time during the term of the agreement, and, provides that if the repurchase right is exercised, Bluestem has the right to retain up to 20% of new accounts subsequently originated. On March 9, 2020, Bluestem and certain of its subsidiaries and affiliates filed Chapter 11 bankruptcy in the United States District Court for the District of Delaware. On August 28, 2020, BLST Operating Company LLC, purchased the Bluestem assets from bankruptcy and assumed Bluestem’s obligations under the parties’ agreements. • Others Under terms of an application transfer agreement with Nissan, the Company has the first opportunity to review for its own portfolio any credit applications turned down by the Nissan’s captive finance company. The agreement does not require the Company to originate any loans, but for each loan originated the Company will pay Nissan a referral fee . In connection with the sale of retail installment contracts through securitizations and other sales, the Company has made standard representations and warranties customary to the consumer finance industry. Violations of these representations and warranties may require the Company to repurchase loans previously sold to on- or off-balance sheet Trusts or other third parties. As of September 30, 2020, there were no loans that were the subject of a demand to repurchase or replace for breach of representations and warranties for the Company’s asset-backed securities or other sales. In the opinion of management, the potential exposure of other recourse obligations related to the Company’s retail installment contract sales agreements is not expected to have a material adverse effect on the Company’s business, financial position, results of operations, or cash flows. Santander has provided guarantees on the covenants, agreements, and obligations of the Company under the governing documents of its warehouse lines and privately issued amortizing notes. These guarantees are limited to the obligations of the Company as servicer. In November 2015, the Company executed a forward flow asset sale agreement with a third party under terms of which the Company committed to sell $350,000 in charged off loan receivables in bankruptcy status on a quarterly basis. However, any sale more than $275,000 is subject to a market price check. The remaining aggregate commitment as of September 30, 2020 and December 31, 2019, not subject to market price check was $27,702 and $39,787, respectively. These matters are ongoing and could in the future result in the imposition of damages, fines or other penalties. No assurance can be given that the ultimate outcome of these matters or any resulting proceedings would not materially and adversely affect the Company’s business, financial condition and results of operations.

Employee Benefit Plans	Employee Benefit Plans The Company has granted stock options to certain executives, other employees, and independent directors under the Company’s 2011 Management Equity Plan (the MEP), which enabled the Company to grant stock option awards up to a total of approximately 29 million common shares (net of shares canceled and forfeited). The MEP expired in January 2015, and the Company will not grant any further awards under the MEP. The Company has granted stock options, restricted stock awards and restricted stock units (RSUs) under the Omnibus Incentive Plan (the Plan), which was established in 2013 and enables the Company to grant awards of cash and of non-qualified and incentive stock options, stock appreciation rights, restricted stock awards, RSUs, and other awards that may be settled in or based upon the value of the Company’s common stock up to a total of 5,192,641 shares of common stock. The Plan was amended and restated as of June 16, 2016. Stock options granted under the MEP and the Plan have an exercise price based on the estimated fair market value of the Company’s common stock on the grant date. The stock options expire ten years after grant date and include both time vesting options and performance vesting options. The fair value of the stock options is amortized into expense over the vesting period as time and performance vesting conditions are met.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries, including certain Trust that are considered VIEs. The Company also consolidates other VIEs for which it is deemed to be the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying condensed consolidated financial statements as of September 30, 2020 and December 31, 2019, and for the three and nine months ended September 30, 2020 and 2019, have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, these financial statements contain all adjustments, consisting of normal and recurring adjustments, necessary for the fair statement of the financial position, results of operations and cash flows for the periods indicated and contain adequate disclosure for the fair statement of this interim financial information. Results of operations for the periods presented herein are not necessarily indicative of results of operations for the entire year. These financial statements should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2019.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates and those differences may be material. The most significant estimates include the determination of credit loss allowance, accretion of discounts and subvention, impairment, fair value
Business Segment Information	Business Segment Information The Company has one reportable segment, Consumer Finance, which includes the Company’s vehicle financial products and services, including retail installment contracts, vehicle leases, and Dealer Loans, as well as financial products and services related to recreational vehicles and marine vehicles. It also includes the Company’s personal loan and point-of-sale financing operations.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Since January 1, 2020, the Company adopted the following FASB ASUs: • Financial Instruments - Credit Losses (Topic 326) • In March 2020, the FASB issued ASU 2020-4, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides temporary optional expedients to reduce the costs and complexity associated with the high volume of contractual modifications expected in the transition away from LIBOR as the benchmark rate in contracts and hedges. These optional expedients allow entities to negate many of the accounting impacts of modifying contracts and hedging relationships necessitated by reference rate reform, allowing them to generally maintain the accounting as if a change had not occurred. The Company adopted this standard during the three months ended March 31, 2020, and will elect the practical expedients relative to the Company’s contracts and hedging relationships modified as a result of reference rate reform through December 31, 2022. These practical expedients did not have a material impact on the Company’s business, financial position, results of operations, or disclosures. • In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general tax accounting principles and simplifying other specific tax scenarios. The Company early adopted this update as of January 1, 2020, and it did not have any material impact to the Company’s business, financial position, results of operations, or disclosures. The adoption of the following ASUs did not have a material impact on the Company’s business, financial position or results of operations. • ASU 2018-17, Consolidation (Topic 10): Targeted Improvements to Related Party Guidance for Variable Interest Entities • ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement
Investment securities	Investment securities Debt securities expected to be held for an indefinite period of time are classified as AFS and recorded on the balance sheet at fair value. If the fair value of an AFS debt security declines below its amortized cost basis and the Company does not have the intention or requirement to sell the security before it recovers its amortized cost basis, declines due to credit factors will be recorded in earnings through the ACL for debt securities, and declines due to non-credit factors will be recorded in AOCI, net of taxes. Subsequent to recognition of a credit loss, improvements to the expectation of collectability will be reversed through the ACL for debt securities. If the Company has the intention or requirement to sell the security, the Company will record its fair value changes in earnings as a direct write down to the security. Increases in fair value above amortized cost basis are recorded in AOCI, net of taxes. The Company conducts an impairment assessment quarterly on all AFS securities with a fair value that is less than their amortized cost basis to determine whether the loss is due to credit factors. Securities for which management expects risk of nonpayment of the amortized cost basis is zero, do not have a reserve. The Company has a zero loss expectation when the securities are issued or guaranteed by certain US government entities, because these entities have a long history of no defaults and the highest credit ratings issued by rating agencies. In the event of a credit loss, the credit component of the impairment is recognized within non-interest income as a separate line item, and by the recording of a valuation reserve. The non-credit component is recorded within AOCI.
Purchased Credit Deteriorated or PCD Loans	Purchased Credit Deteriorated or PCD loansLoans that the Company deems at acquisition to have more than insignificant deterioration in credit quality since origination (i.e., Purchased Credit Deteriorated or PCD loans) require the recognition of an allowance for credit losses at purchase. The allowance for credit losses is added to the purchase price at the date of acquisition to determine the initial amortized cost basis of the PCD loan. The allowance for credit losses is calculated using the same methodology as originated loans, as described below. Alternatively, the Company can elect the fair value option at the time of purchase for any financial asset. Under the FVO, loans are recorded at fair value with changes in value recognized immediately in income. There is no ACL for loans under an FVO.
Credit Loss Expense and Allowance for Credit losses	Credit Loss Expense and Allowance for Credit losses General Credit loss expenses are charged to operations in amounts sufficient to maintain the ACL at levels considered adequate to cover expected credit losses in the Company’s retail installment contracts. The allowance for expected credit losses on retail installment contracts is measured based on a lifetime expected loss model, which means that it is not necessary for a loss event to occur before a credit loss is recognized. Management’s estimate of expected credit losses is based on an evaluation of relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the future collectability of the reported amounts. Management's evaluation takes into consideration the risks in the portfolio, past loss experience, specific loans with loss potential, geographic and industry concentrations, delinquency trends, economic forecasts and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the ACL may be necessary if conditions differ substantially from the assumptions used in making the evaluations. The Company measures expected losses of all components on an amortized cost basis. For all loans except TDRs, the Company has elected to exclude accrued interest receivable balances from the measurement of expected credit losses because it applies a nonaccrual policy that results in the timely write off of uncollectible accrued interest. For loans on nonaccrual status, interest income is recognized on a cash basis, and the accrual of interest is resumed and reinstated if a delinquent account subsequently becomes 60 days or less past due. Methodology The Company uses several methodologies for the measurement of ACL. The ACL is made up of a quantitative and a qualitative component. To determine the quantitative component, the Company generally uses a DCF approach for determining ACL for TDRs and other individually assessed loans, and a non-DCF approach for other loans. Expected credit losses are estimated on an individual basis only if the individual asset or exposure does not share similar risk attributes with other financial assets or exposures, including when an asset is treated as a collateral dependent asset. The ACL estimate includes significant assumptions including the reasonable and supportable economic forecast period, which considers the availability of forward-looking scenarios and their respective time horizons, as well as the reversion method to historical losses. This method results in a single, quantitatively consistent credit model across the entire projection period as the macroeconomic effects in the historical data are controlled for the estimate of the long-run loss level. Models The Company uses a statistical methodology based on an ECL approach that focuses on forecasting the ECL components (i.e., probability of default, payoff, loss given default and exposure at default) on a loan level basis to estimate the expected future life time losses. The individual loan balances used in the models are measured on an amortized cost basis. • In calculating the probability of default and payoff, the Company developed model forecasts, which consider variables such as delinquency status, loan tenor and other credit quality indicators. • The loss given default component forecasts the extent of losses given that a default has occurred and considers variables such as collateral, loan-to-value and other credit quality indicators. • The exposure at default component captures the effects of expected partial prepayments and underpayments that are expected to occur during the forecast period and considers variable such as loan-to-value, collateral and other credit quality indicators. The above ECL components are used to compute an ACL based on the weighted average of the results of the macroeconomic scenarios. The weighting of these scenarios is governed and approved quarterly by management through established committee governance. These ECL components are inputs to both the Company’s DCF approach for TDR and individually assessed loans and non-DCF approach for other loans. When using a non-DCF method to measure the ACL, the Company measures ECL over the asset’s contractual term, adjusted for (a) expected prepayments; (b) expected extensions associated with assets for which management has a reasonable expectation at the reporting date that it will execute a TDR with the borrower; and (c) expected extensions or renewal options (excluding those that are accounted for as derivatives) included in the original or modified contract at the reporting date that are not unconditionally cancellable by the entity. DCF approaches A DCF method measures expected credit losses by forecasting expected future principal and interest cash flows and discounting them using the financial asset’s EIR. The ACL reflects the difference between the amortized cost basis (including accrued interest) and the present value of the expected cash flows. When using a DCF method to measure the ACL, the period of exposure is determined as a function of the Company’s expectations of the timing of principal and interest payments. The Company considers estimated prepayments in the future principal and interest cash flows when utilizing a DCF Method. The Company generally uses a DCF approach for TDRs. Collateral - Dependent Assets A loan is considered a Collateral Dependent Financial Asset when (a) the Company determines foreclosure is probable or (b) the borrower is experiencing financial difficulty and the Company expects repayment to be provided substantially through the operation or sale of the collateral. For all collateral dependent loans such as certain bankruptcy modifications, the Company measures the ACL as the difference between the loan’s amortized cost basis and the fair value of the underlying collateral as of the reporting date, adjusted for expected costs to sell. If repayment or satisfaction of the loan is dependent only on the operation, rather than the sale, of the collateral, the measure of credit losses does not incorporate estimated costs to sell. The collateral dependent loan is written down (i.e. charged off) to the fair value of the collateral adjusted for costs to sell (if repayment from sale is expected.) Any subsequent increase or decrease in the collateral’s fair value less cost to sell is recognized as an adjustment to the related loan’s ACL. Negative allowance Negative allowance is defined as the amount of future recovery expected for accounts that have already been charged-off. The Company performs an analysis of the actual historical recovery values to determine the pattern of recovery and expected rate of recovery over a given historic period, and uses the results of this analysis to determine negative allowance. Negative allowance reduces the ACL. Qualitative Reserve Regardless of the extent of the Company's analysis of customer performance, portfolio evaluations, trends or risk management processes established, a level of imprecision will always exist due to the judgmental nature of loan portfolio and/or individual loan evaluations. The Company maintains a qualitative reserve as a component of the ACL to recognize the existence of these exposures. Imprecisions include loss factors inherent in the loan portfolio that may not have been discreetly contemplated in deriving the quantitative component of the allowance, as well as potential variability in estimates. The qualitative adjustment is also established in consideration of several factors such as the interpretation of economic trends, changes in the nature and volume of our loan portfolio, trends in delinquency and collateral values, and concentration risks. This analysis is conducted at least quarterly, and the Company revises the qualitative component of the allowance when necessary in order to address improving or deteriorating credit quality trends or specific risks associated with loan pool classification, not otherwise captured in the quantitative models. Governance A comprehensive analysis of the ACL is performed by the Company on a quarterly basis. Management regularly monitors the condition of borrowers and assesses both internal and external factors in determining whether any relationships have deteriorated considering factors such as historical loss experience, trends in delinquency, changes in risk composition and underwriting standards, experience and ability of staff and regional and national economic conditions, trends and forecasts. Risk factors are continuously reviewed and revised by management when conditions warrant. The Company's reserves are principally based on various models subject to the Company's model risk management framework. New models are approved by the SHUSA's Model Risk Management Committee. Models, inputs and documentation are further reviewed and validated at least annually, and the Company completes a detailed variance analysis of historical model projections against actual observed results on a quarterly basis. Required actions resulting from the Company's analysis, if necessary, are governed by its ACL Committee. Reserve levels are collectively reviewed for adequacy and approved quarterly by Board-level committees.

This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurement of its derivatives. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings and guarantees. The Company utilizes the exception in ASC 820-10-35-18D (commonly referred to as the “portfolio exception”) with respect to measuring counterparty credit risk for instruments (Note 9). (b) The Company's AFS debt securities includes U.S. Treasury securities that are valued utilizing observable market quotes. The Company obtains vendor trading platform data (actual prices) from a number of live data sources, including active market makers and interdealer brokers and its securities are therefore, classified as Level 2. (c) For certain retail installment contracts reported in finance receivables held for investment, net, the Company has elected the fair value option. The fair values of the retail installment contracts are estimated using a DCF model are classified as Level 3. As of December 31, 2019, Company had used the most recent purchase price as the fair value for certain loans and hence classified those retail installment contracts as Level 2. Changes in the fair value are recorded in investment gains (losses), net in the condensed consolidated statement of income. (d) The aggregate fair value of retail installment contracts in non-accrual status, as of September 30, 2020 and December 31, 2019, i s $2,031 a nd $9,511, respectively.

Assets and Liabilities Measured at Fair Value on Nonrecurring Basis	The following table presents the Company’s assets and liabilities that are measured at fair value on a nonrecurring basis at September 30, 2020 and December 31, 2019, respectively: Nine Months Ended September 30, 2020 Year Ended December 31, 2019 Total Lower of cost or fair value expense Total Lower of cost or fair value expense Other assets — vehicles (a) $ 370,678 $ — $ 341,465 $ — Personal loans held for sale (b) 763,292 241,198 1,007,105 408,700 Auto loans impaired due to bankruptcy (c) 188,226 — 200,504 9,106 ( a) The Company estimates the fair value of its vehicles, which are obtained either through repossession or lease termination, using historical auction rates and current market levels of used car prices. (b) The estimated fair value for personal loans held for sale is calculated based on the lower of market participant view and a DCF analysis in which the Company uses significant unobservable inputs on key assumptions. The lower of cost or fair value adjustment for personal loans held for sale includes customer default activity and adjustments related to the net change in the portfolio balance during the reporting period. (c) For loans that are considered collateral-dependent, such as certain bankruptcy loans, impairment is measured based on the fair value of the collateral, less its estimated cost to sell. For the underlying collateral, the estimated fair value is obtained using historical auction rates and current market levels of used car prices. No additional lower of cost or fair value expense was recorded for the nine months ended September 30, 2020.
Quantitative Information About Significant Unobservable Inputs for Liabilities Measured at Fair Value	The following table presents quantitative information about the significant unobservable inputs for assets and liabilities measured at fair value on a recurring and nonrecurring basis at September 30, 2020 and December 31, 2019, respectively: Financial Instruments Fair Value at September 30, 2020 Valuation Technique Unobservable Inputs Range (weighted average) (a) Financial Assets: Retail installment contracts held for investment $ 8,248 Discounted Cash Flow Discount Rate 8%-14% (9%) Default Rate 4%-20% (5%) Prepayment Rate 15%-25% (15%) Loss Severity Rate 50%-60% (56%) Personal loans held for sale (b) $ 763,292 Lower of Market or Income Approach Market Approach Market Participant View 60%-70% Income Approach Discount Rate 20%-30% Default Rate 40%-50% Net Principal & Interest Payment Rate 65%-75% Loss Severity Rate 90%-95% (a) Weighted average was developed by weighting the associated relative unpaid principal balances.

(b) Finance receivables held for investment, net — Finance receivables held for investment, net are carried at amortized cost, net of an allowance. These receivables exclude retail installment contracts that are measured at fair value on a recurring and nonrecurring basis. The estimated fair value for the underlying financial instruments is determined as follows: • Retail installment contracts held for investment and purchased receivables - credit deteriorated — As of December 31, 2019 , the Company used the most recent purchase price as the fair value for certain loans and therefore, classified those retail installment contracts as Level 2. The estimated fair value of all finance receivables at September 30, 2020 is estimated using a DCF model, and such receivables are classified as Level 3. • Finance lease receivables — Finance lease receivables are carried at gross investments, net of unearned income and allowance for lease losses. Management believes that the terms of these credit agreements approximate market terms for similar credit agreements. • Receivables from dealers and personal loans held for investment — Receivables from dealers and personal loans held for investment are carried at amortized cost, net of credit loss allowance. Management believes that the terms of these credit agreements approximate market terms for similar credit agreements. (c) Investments in debt securities held to maturity - Investments in debt securities held to maturity are recorded at amortized cost and are priced by third-party pricing vendors. The third-party vendors use a variety of methods when pricing these securities that incorporate relevant observable market data to arrive at an estimate of what a buyer in the marketplace would pay for a security under current market conditions. These investment securities are, therefore, considered Level 2. (d) Notes payable — facilities with third parties — The carrying amount of notes payable related to revolving credit facilities is estimated to approximate fair value. Management believes that the terms of these credit agreements approximate market terms for similar credit agreements as the facilities are subject to short-term floating interest rates that approximate rates available to the Company. (e) Notes payable — secured structured financings — The estimated fair value of notes payable related to secured structured financings is calculated based on market observable prices and spreads for the Company’s publicly traded debt and market observed prices of similar notes issued by the Company, or recent market transactions involving similar debt with similar credit risks, which are considered Level 2 inputs. The estimated fair value of notes payable related to privately issued amortizing notes is calculated based on a combination of credit enhancement review, discounted cash flow analysis and review of market observable spreads for similar liabilities. In conducting this analysis, the Company uses significant unobservable inputs on key assumptions, which are considered Level 3 inputs. (f) Notes payable — facilities with Santander and related subsidiaries — The carrying amount of floating rate notes payable to a related party is estimated to approximate fair value as the facilities are subject to short-term floating interest rates that approximate rates available to the Company. The fair value premium/discount of the fixed rate promissory notes are derived from changes in the Company’s unsecured cost of funds since the time of issuance and weighted average life of these notes.
