Description of Business, Basis of Presentation, and Significant Accounting Policies and Practices	Description of Business, Basis of Presentation, and Significant Accounting Policies and Practices 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 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. On June 28, 2019, the Company entered into an Amendment to the Chrysler Agreement with FCA, which modified the Chrysler Agreement to, among other things, adjust certain performance metrics, exclusivity commitments and payment provisions. The Amendment also terminated the previously disclosed tolling agreement, dated July 11, 2018, between the Company and FCA. 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 December 31, 2019, the Company was owned approximately 72.4% by SHUSA, a subsidiary of Santander, and approximately 27.6% by other shareholders. Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, including certain Trusts, which are considered VIEs. The Company also consolidates other VIEs for which it was deemed to be the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosures of contingent assets and liabilities, as of the date of the financial statements and the amount of revenue and expenses during the reporting periods. Actual results could differ from those estimates and those differences may be material. These estimates include the determination of credit loss allowance, discount accretion, impairment, fair value, 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 potentially 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. Accounting Policies Finance Receivables Finance receivables are comprised of retail installment contracts, purchased receivables - credit impaired, receivables from dealer, personal loans, and finance lease receivables. Finance receivables are classified as either held for sale or held for investment, depending on the Company’s intent and ability to hold the underlying contract for the foreseeable future or until maturity or payoff. Most of the Company’s retail installment contracts held for investment are pledged under its warehouse facilities or securitization transactions. Retail Installment Contracts Retail installment contracts consist largely of nonprime automobile finance receivables, which are acquired from dealers at a nonrefundable discount from the contractual principal amount. Retail installment contracts also include receivables originated through a direct lending program and loan portfolios purchased from other lenders. Retail installment contracts are primarily classified as held for investment and carried at amortized cost, net of allowance for credit losses. The Company has elected the fair value option for certain non-performing loans acquired through the exercise of a clean-up call. Accordingly, changes in the fair value of these finance receivables, which are based upon fair value estimates (Note 15), are reported in investment gains (losses), net, in the consolidated statements of income and comprehensive income. Interest is accrued when earned in accordance with the terms of the retail installment contract. The accrual of interest is discontinued and reversed once a retail installment contract becomes more than 60 days past due, and is resumed and reinstated if a delinquent account subsequently becomes 60 days or less past due. For loans on nonaccrual status, interest income is recognized on a cash basis. 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. Payments generally are applied to interest first, then principal, then fees, regardless of a contract’s accrual status. The payment following the partial payment must be a full payment, or the account will move into delinquency status at that time. The amortization of discounts, subvention payments from manufacturers, and other origination costs on retail installment contracts held for investment are recognized as adjustments to the yield of the related contract using the effective interest method. The Company estimates future principal prepayments specific to pools of homogenous loans which are based on the vintage, credit quality at origination and term of the loan. Prepayments in our portfolio are sensitive to credit quality, with higher credit quality loans generally experiencing higher voluntary prepayment rates than lower credit quality loans. The impact of defaults is not considered in the prepayment rate; the prepayment rate only considers voluntary prepayments. The resulting prepayment rate specific to each pool is based on historical experience, and is used as an input in the calculation of the constant effective yield. Our estimated weighted average prepayment rates ranged from 5.1% to 11.0% as of December 31, 2019, and 5.7% to 10.8% as of December 31, 2018. Purchased Receivables Portfolios - Receivables portfolios purchased from other lenders or pursuant to a repurchase obligation that are purchased at amounts less than the principal amount of those receivables, resulting in a discount to par, are accounted for in accordance with ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality , if the discount was attributable, at least in part, to the expectation that not all contractual cash flows will be received from borrowers, which did not exist at the origination of the loans. The excess of the estimated undiscounted principal, interest, and other cash flows expected to be collected over the initial investment in the acquired loans, or accretable yield, is accreted to interest income over the expected life of the loans using the effective interest rate method. The nonaccretable difference is the excess between the contractually required payments and the amount of cash flows, considering the impact of prepayments, expected to be collected. The nonaccretable difference is not accreted into income. Any deterioration in the performance of the purchased portfolios results in an incremental impairment. Improvements in performance of the purchased pools that significantly increase actual or expected cash flows result in first a reversal of previously recorded impairment and then in a transfer of the excess from nonaccretable difference to accretable yield, which will be recorded as finance income over the remaining life of the receivables. Receivable portfolios purchased from other lenders are considered non-credit impaired loans if they either do not have evidence of credit quality deterioration or it was not probable that the Company would not collect all contractually required payments, which will be evaluated using a number of factors including the loan’s delinquency status, borrower’s credit status, and roll rates. Accordingly, these loans will be accounted for in accordance with ASC 310 - 20. Under ASC 310-20, the difference between the loan’s principal balance, at the time of purchase, and the fair value is recognized as an adjustment of yield over the life of the loan. All other policies related to interest income, calculation of allowance for loan losses, and recognizing TDRs would be similar to retail installment contracts acquired individually and originated by the Company. Personal Loans, Net Personal loans, net, consists of revolving finance receivables acquired individually under terms of the Company’s agreements with certain third parties who originate and continue to service the loans. Interest is accrued when earned in accordance with the terms of the contract. The accrual of interest on revolving personal loans continues until the receivable becomes 180 days past due, at which point the principal amount and interest are charged off. Receivables from Dealers Receivables from dealers include Floorplan Loans provided to dealerships to finance new and used vehicles for their inventory. Receivables from dealers also include real estate loans and working capital revolving lines of credit. Interest on these loans is accrued when earned in accordance with the agreement with the dealer. Finance Receivables Held for Sale, Net Finance receivables, which may include any of the receivables described above, that the Company does not have the intent and ability to hold for the foreseeable future or until maturity or payoff, including those previously designated as held for investment and subsequently identified for sale, are classified as held for sale, at origination or at the time a decision to sell is made. Finance receivables designated as held for sale are carried at the lower of cost or market, as determined on an aggregate basis. Cost, or recorded investment, includes deferred net origination fees and costs, premium or discounts, accrued interest, manufacturer subvention (if any) and any direct write-down of the investment. When loans are transferred from held for investment, the Company records charge offs as per its charge off policy. Any excess allowance is reversed through provision expense. Subsequent to the initial measurement of retail installment contracts and personal loans held for sale, market declines in the recorded investment, whether due to credit or market risk, are recorded through investment gains (losses), net of lower of cost or market adjustments. Provision for Credit Losses Provisions for credit losses are charged to operations in amounts sufficient to support the credit loss allowance in accordance with the Company’s estimate. The Company estimates an allowance on retail installment contracts and personal loans held for investment not classified as TDRs at a level considered adequate to cover expected net credit losses inherent in the recorded investment of that portfolio. Probable losses are estimated based on contractual delinquency status and historical loss experience, in addition to the Company’s judgment of estimates of the value of the underlying collateral, changes in the used vehicle value index, delinquency status, historical collection rates and other information in order to make the necessary judgments as to probable loan losses. For loans classified as TDRs, impairment is generally measured based on the present value of expected future cash flows discounted at the original effective interest rate. For loans that are considered collateral-dependent, such as certain bankruptcy modifications, impairment is measured based on the fair value of the collateral, less its estimated cost to sell. Provisions for credit losses are also charged to operations for impairment on TDRs. Retail installment contracts are charged off against the allowance in the month in which the account becomes greater than 120 days contractually delinquent if the Company has not repossessed the related vehicle. The Company charges off accounts in repossession when the automobile is repossessed and legally available for disposition. A net charge-off represents the difference between the estimated sales proceeds and the Company’s recorded investment in the related contract. Costs to sell the vehicle are presented in repossession expense. Accounts in repossession that have been charged off and are pending liquidation are removed from retail installment contracts and the related repossessed automobiles are included in other assets in the Company’s consolidated balance sheets. In addition to maintaining a general allowance based on risk ratings, receivables from dealers are evaluated individually for impairment with allowances established for receivables determined to be individually impaired. Receivables from dealers are charged off against these allowances at the time that the credit is considered uncollectable and of such little value that it does not warrant consideration as an active asset. Troubled Debt Restructurings A modification of finance receivable terms is considered a troubled debt restructuring (TDR) if the Company grants a concession it would not otherwise have considered to a borrower for economic or legal reasons related to the debtor’s financial difficulties. The Company considers TDRs to include all retail installment contracts or personal revolving loans that have been modified at least once, deferred for a period of 90 days or more, or deferred at least twice. Additionally, restructurings through bankruptcy proceedings are deemed to be TDRs. The purchased receivables portfolio - credit impaired, operating and finance leases, and loans held for sale are excluded from the scope of the applicable guidance, and none of the Company’s Dealer Loans have been modified or deferred. For TDRs, impairment is generally measured based on the difference between the recorded investment of the loan and the present value of the expected future cash flows of the loan. The loan may also be measured for impairment based on the fair value of the underlying collateral less costs to sell for loans that are collateral dependent. TDRs are evaluated for impairment individually or in aggregate for those loans with similar risk characteristics. Leased Vehicles, Net (SC as Lessor) Most vehicles for which the Company is the lessor are classified as operating leases, as they do not meet the accounting requirements to be classified as a finance lease. The net capitalized cost of each lease is recorded as an asset and depreciated on a straight-line basis over the contractual term of the lease to the expected residual value. The expected residual value and, accordingly, the monthly depreciation expense may change throughout the term of the lease. The Company estimates expected residual values using independent data sources and internal statistical models that take into consideration economic conditions, current auction results, the Company’s remarketing abilities, and manufacturer vehicle and marketing programs. Over the life of the lease, the Company evaluates the adequacy of the estimate of the residual value and may make adjustments to the depreciation rates to the extent the expected value of the vehicle at lease termination changes. Lease payments due from customers are recorded as income until and unless a customer becomes more than 60 days delinquent, at which time the accrual of revenue is discontinued and reversed. The accrual is resumed and reinstated if a delinquent account subsequently becomes 60 days or less past due. Subvention payments from the manufacturer, down payments from the customer, and initial direct costs incurred in connection with originating the lease are treated as a reduction to the cost basis of the underlying lease asset and are amortized on a straight-line basis over the contractual term of the lease. The amortization of manufacturer subvention payments is reflected as a reduction to depreciation expense over the life of the contract. The Company periodically evaluates its investment in operating leases for impairment if circumstances, such as a systemic and material decline in used vehicle values, indicates that an impairment may exist. These circumstances could include, for example, shocks to oil and gas prices (which may have a pronounced impact on certain models of vehicles) or pervasive manufacturer defects (which may systemically affect the value of a particular vehicle brand or model). Impairment is determined to exist if fair value of the leased asset is less than carrying value and it is determined that the net carrying value is not recoverable. The net carrying value of a leased asset is not recoverable if it exceeds the sum of the undiscounted expected future cash flows expected to result from the lease payments and the estimated residual value upon eventual disposition. If our operating lease assets are considered to be impaired, the impairment is measured as the amount by which the carrying amount of the assets exceeds the fair value as estimated by discounted cash flows. No impairment was recognized in 2019, 2018, or 2017. Finance Lease Receivables, net (SC as Lessor) Leases classified as finance leases are accounted for as direct financing leases. Minimum lease payments plus the estimated residual value of the leased vehicle are recorded as the gross investment. The difference between the gross investment and the cost of the leased vehicle is recorded as unearned income. Direct financing leases are reported at the aggregate of gross investments, net of unearned income and allowance for lease losses. Income for direct financing leases is recognized using the effective interest method, which provides a constant periodic rate of return on the outstanding investment on the lease. Fees, commissions, and other Fees, commissions, and other primarily include late fees, miscellaneous, and other income, and are generally recorded when there is no doubt as to the collectability of the related receivable. Repossessed Vehicles and Repossession Expense Repossessed vehicles represent vehicles the Company has repossessed due to the borrowers’ default on the payment terms of the retail installment contracts, loans or leases. The Company generally begins repossession activity once a customer has reached 60 days past due. The customer has an opportunity to redeem the repossessed vehicle by paying all outstanding balances, including finance charges and fees. Any vehicles not redeemed are sold at auction. The Company records the vehicles currently in its inventory at the lower of cost or estimated fair value, net of estimated costs to sell (See Notes 9 and 15). Repossession expense includes the costs to repossess and sell vehicles obtained due to borrower default. These costs include transportation, storage, rekeying, condition reports, legal fees, the fees paid to repossession agents and auction fees. Sales of Finance Receivables and Leases The Company transfers retail installment contracts into newly formed Trusts, which then issue one or more classes of notes payable backed by the retail installment contracts. The Company’s continuing involvement with the credit facilities and Trusts are in the form of servicing loans held by the special purpose entities (SPEs) and, generally, through holding a residual interest in the SPE. These transactions are structured without recourse. The Trusts are considered VIEs under GAAP and are consolidated when the Company has: (a) power over the significant activities of the entity and (b) an obligation to absorb losses or the right to receive benefits from the VIE which are potentially significant to the VIE. The Company has power over the significant activities of those Trusts as servicer of the financial assets held in the Trust. Servicing fees are not considered significant variable interests in the Trusts; however, when the Company also retains a residual interest in the Trust, either in the form of a debt security or equity interest, the Company has an obligation to absorb losses or the right to receive benefits that are potentially significant to the SPE. For all VIEs in which the Company is involved, the Company assesses whether it is the primary beneficiary of the VIE on an ongoing basis. In circumstances where the Company have both the power to direct the activities that most significantly impact the VIEs performance and the obligation to absorb losses or the right to receive benefits of the VIE that could be significant, the Company would conclude that it is the primary beneficiary of the VIE, and accordingly, these Trusts are consolidated within the consolidated financial statements, and the associated retail installment contracts, borrowings under credit facilities and securitization notes payable remain on the consolidated balance sheets. In situations where the Company is not deemed to be the primary beneficiary of the VIE, the Company does not consolidate the VIE and only recognizes its interests in the VIE. These securitizations involving Trusts are treated as sales of the associated retail installment contracts. While these Trusts are included in the consolidated financial statements, these Trusts are separate legal entities; thus, the finance receivables and other assets sold to these Trusts are legally owned by these Trusts, are available only to satisfy the notes payable related to the securitized retail installment contracts, and are not available to the Company’s creditors or other subsidiaries. The Company also sells retail installment contracts and leases to VIEs or directly to third parties, which the Company may determine meet sale accounting treatment in accordance with the applicable guidance. Due to the nature, purpose, and activity of these transactions, the Company either does not hold potentially significant variable interests or is not the primary beneficiary as a result of the Company’s limited further involvement with the financial assets. The transferred financial assets are removed from the Company’s consolidated balance sheets at the time the sale is completed. The Company generally remains the servicer of the financial assets and receives servicing fees. The Company also recognizes a gain or loss for the difference between the fair value, as measured based on sales proceeds plus (or minus) the value of any servicing asset (or liability) retained and carrying value of the assets sold. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company has maintained balances in various operating and money market accounts in excess of federally insured limits. Restricted Cash Cash deposited to support securitization transactions, lockbox collections, and the related required reserve accounts is recorded in the Company’s consolidated balance sheet as restricted cash. Excess cash flows generated by the securitization trusts are added to the restricted cash reserve account, creating additional over-collateralization until the contractual securitization requirement has been reached. Once the targeted reserve requirement is satisfied, additional excess cash flows generated by the Trusts are released to the Company as distributions from the Trusts. Lockbox collections are added to restricted cash and released when transferred to the appropriate warehouse facility or Trust. Income Taxes Income tax expense consists of income taxes currently payable and deferred income taxes computed using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. The deferred tax asset is subject to reduction by a valuation allowance in certain circumstances. This valuation allowance is recognized if it is more likely than not that some portion or all of the deferred tax asset will not be realized based on a review of available evidence. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records the benefit of uncertain tax positions in the consolidated financial statements when such positions (1) meet a more-likely-than-not threshold, (2) are settled through negotiation or litigation, or (3) the statute of limitations for the taxing authority to examine the position has expired. Tax benefits associated with an uncertain tax position are derecognized in the period in which the more-likely-than-not recognition threshold is no longer satisfied. Furniture and Equipment Furniture and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets, which range from three Operating Leases (SC as Lessee) Operating lease ROU assets and liabilities are recognized based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate for a collateralized borrowing based on the duration of the lease term in determining the present value of lease payments. The lease term includes options to extend or terminate a lease when the Company considers it reasonably certain that such options will be exercised. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease expense for operating lease is recognized on a straight-line basis over the lease term. Goodwill and Intangibles Goodwill represents the excess of consideration paid over fair value of net assets acquired in business combinations. Intangibles represent intangible assets purchased or acquired through business combinations, including trade names and software development costs. Intangibles are amortized over their estimated useful lives. The Company tests goodwill for impairment annually in accordance with the provisions of ASC 350, Intangibles-Goodwill and Other . Derivative Financial Instruments Derivative financial instruments are recognized as either assets or liabilities in the consolidated balance sheets at fair value. The accounting for changes in the fair value of each derivative financial instrument depends on whether it has been designated and qualifies as a hedge for accounting purposes, as well as the type of hedging relationship identified. The Company does not use derivative instruments for trading or speculative purposes. Interest Rate Swap Agreements — The Company uses interest rate swaps to hedge the variability of cash flows on securities issued by securitization Trusts and borrowings under the Company’s warehouse facilities. Certain interest rate swap agreements are designated and qualify as cash flow hedges, and are highly effective in reducing exposure to interest rate risk from both an accounting and an economic perspective. At hedge inception and at least quarterly, the interest rate swap agreements designated as accounting hedges are assessed to determine their effectiveness in offsetting changes in the cash flows of the hedged items and whether those interest rate swap agreements may be expected to remain highly effective in future periods. The Company uses the hypothetical derivative method to assess hedge effectiveness of cash flow hedges on a prospective and retrospective basis. At December 31, 2019, all of the Company’s interest rate swap agreements designated as cash flow hedges are deemed to be effective hedges for accounting purposes. The changes in the fair value of the interest rate swaps qualifying as cash flow hedges are included as a component of other comprehensive income(loss), net of estimated income taxes, as an unrealized gain or loss on cash flow hedges. These unrealized gains or losses are recognized as adjustments to income over the same period in which cash flows from the related hedged item affect earnings. The Company discontinues hedge accounting prospectively when it is determined that an interest rate swap agreement has ceased to be effective as an accounting hedge or if the underlying hedged cash flow is no longer probable of occurring. The Company has also entered into interest rate swap agreements related to its securitization trusts and warehouse facilities that are not designated as hedges. These agreements are intended to reduce the risk of interest rate fluctuations. For the interest rate swap agreements not designated as hedges, any gains or losses are included in the Company’s earnings as a component of interest expense. Interest Rate Cap Agreements — The Company purchases interest rate cap agreements to limit floating rate exposures on securities issued in credit facilities. As part of the interest rate risk management strategy, and when economically feasible, the Company may simultaneously sell a corresponding written option to offset the premium paid to purchase the interest rate cap agreement and thus retain the interest rate risk. Because these instruments entered into directly by the Company or through SPEs are not designated for hedge accounting, changes in the fair value of interest rate cap agreements purchased by the SPEs and written option sold by the Company are recorded in interest expenses on the consolidated statements of income and comprehensive income. Stock-Based Compensation The Company measures the compensation cost of stock-based awards using the estimated fair value of those awards on the grant date, and recognizes the cost as expense over the vesting period of the awards (see Note 16). Earnings per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised. It is computed after giving consideration to the weighted average dilutive effect of the Company’s stock options and restricted stock grants. Because the Company has issued participating securities in the form of unvested restricted stock that has dividend rights, the Company applies the two-class method when computing earnings per share. Recently Adopted Accounting Standards Since January 1, 2019, the Company adopted the following FASB ASUs: • In February 2016, the FASB issued ASU 2016-02, Leases . The primary effect of the ASU is to replace the existing accounting requirements for operating leases for lessees. Lessee accounting requirements for finance leases and lessor accounting requirements for operating leases and sales type and direct financing leases (sales-type and direct financing leases were both previously referred to as capital leases) are largely unchanged. The Company adopted this standard using the modified retrospective method and utilized the optional transition method under which we continue to apply the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative period presented. For all our operating leases (primarily our office space/facility leases), where the Company is a lessee, adoption of the new standard resulte

Most of the Company’s retail installment contracts held for investment are pledged against warehouse lines or securitization bonds (Note 6). Most of the borrowers on the Company’s retail installment contracts held for investment are retail consumers; however, $741,592 and $537,922 of the unpaid principal balance represented fleet contracts with commercial borrowers as of December 31, 2019 and 2018, respectively. During the years ended December 31, 2019 and 2018, the Company originated (including the SBNA originations program) $12,762,677 and $7,927,597, respectively, in CCAP loans which represented 56% and 46%, respectively, of the total retail installment contract originations (including the SBNA originations program). As of December 31, 2019, borrowers on the Company’s retail installment contracts held for investment are located in Texas (17%), Florida (11%), California (9%), Georgia (6%) and other states each individually representing less than 5% of the Company’s total portfolio. Purchased receivables A. Purchased receivables portfolios - credit impaired, accounted under ASC 310-30 Purchased receivables portfolios - credit impaired, which were acquired with deteriorated credit quality, is comprised of the following at December 31, 2019 and 2018: December 31, 2019 December 31, 2018 Outstanding balance $ 21,542 $ 30,631 Outstanding recorded investment, net of impairment 12,272 19,390 Changes in accretable yield on the Company’s purchased receivables portfolios - credit impaired for the periods indicated were as follows: For the Year Ended December 31, 2019 2018 2017 Balance — beginning of year $ 18,145 $ 19,464 $ 107,041 Accretion of accretable yield (4,007) (8,569) (30,129) Disposals/transfers — — (62,183) Reclassifications from (to) nonaccretable difference (a) 11 7,250 4,735 Balance — end of year $ 14,149 $ 18,145 $ 19,464 (a) Reclassifications from (to) nonaccretable difference represents the increases (decreases) in accretable yield resulting from higher (lower) estimated undiscounted cash flows. B. Purchased receivables portfolios, accounted under ASC 310-20 and/or Fair Value Option During the year ended December 31, 2019, 2018 and 2017, the company purchased financial receivables from third party lenders for $1.09 billion, $67,249 and zero, respectively. The unpaid principal balance of these loans as of the acquisition date was $1.12 billion, $74,086 and zero, respectively. For the year ended 2019, the Company determined that majority of the acquired loans were non-credit impaired loans because they either did not have evidence of credit quality deterioration or it was not probable that the Company would not collect all contractually required payments, which was evaluated using a number of factors including the loan’s delinquency status, borrower’s credit status, and roll rates. The company elected the fair value option for $22 million of purchased loans deemed to be credit-impaired since it was determined that not all contractually required payments would be collected. Refer to Note 15 - "Fair Value of Financial Instruments" to these accompanying consolidated financial statements for additional details. Accordingly, the majority of these loans are accounted for in accordance with ASC 310-20. Under ASC 310-20, the difference between the loan's principal balance, at the time of purchase, and the fair value is recognized as an adjustment of yield over the life of the loan. All other policies related to interest income, calculation of allowance for loan losses, and recognizing TDRs would be similar to retail installment contracts and are originated by the Company. During the years ended December 31, 2018 and 2017, the Company did not acquire any vehicle loan portfolios for which it was probable at acquisition that not all contractually required payments would be collected. In addition, during the years ended December 31, 2019, 2018 and 2017 the Company recognized certain retail installment contracts with an unpaid principal balance of $74,718, $213,973 and $290,613 respectively, held by non-consolidated securitization Trusts, under optional clean-up calls (Note 7). Following the initial recognition of these loans at fair value, the performing loans in the portfolio are carried at amortized cost, net of allowance for credit losses. The Company elected the fair value option for all non-performing loans acquired (more than 60 days delinquent as of the re-recognition date), for which it was probable that not all contractually required payments would be collected (Note 15). Receivable from Dealers The receivables from dealers held for investment are all Chrysler Agreement-related. As of December 31, 2019, borrowers on these dealer receivables are located in Virginia (70%) and New York (30%). Held For Sale The carrying value of the Company’s finance receivables held for sale, net is comprised of the following at December 31, 2019 and 2018: December 31, 2019 December 31, 2018 Personal loans $ 1,007,105 $ 1,068,757 Sales of retail installment contracts and proceeds from sales of charged-off assets for the years ended December 31, 2019, 2018 and 2017 were as follows: For the Year Ended December 31, 2019 2018 2017 Sales of retail installment contracts to third parties $ — $ — $ 260,568 Sales of retail installment contracts to affiliates — 2,905,922 2,583,341 Proceeds from sales of charged-off assets to third parties 55,220 55,902 93,619

Credit Loss Allowance and Credi

Credit Loss Allowance and Credit Quality	12 Months Ended

Loans and Leases Receivable Disclosure [Abstract]
Credit Loss Allowance and Credit Quality	Credit Loss Allowance and Credit Quality Credit Loss Allowance The Company estimates the allowance for credit losses on retail installment contracts (including loans acquired from third party lenders that are considered to have no credit deterioration at acquisition) and personal loans held for investment, not classified as TDRs, based on delinquency status, historical loss experience, estimated values of underlying collateral, when applicable, and various economic factors. In developing the allowance, the Company utilizes a loss emergence period assumption, a loss given default assumption applied to the recorded investment, and a probability of default assumption. The loss emergence period assumption represents the average length of time between when a loss event is first estimated to have occurred and when the account is charged-off. The recorded investment represents unpaid principal balance adjusted for unaccreted net discounts, subvention from manufacturers, and origination costs. Under this approach, the resulting allowance represents the expected net losses of recorded investment inherent in the portfolio. The Company uses a transition based Markov model for estimating the allowance for credit losses on retail installment contracts. This model utilizes the recently observed loan transition rates from various loan statuses, including delinquency and accounting statuses from performing to charge off, to forecast future losses. For loans classified as TDRs, impairment is generally measured based on the present value of expected future cash flows discounted at the original effective interest rate. For loans that are considered collateral-dependent, such as certain bankruptcy modifications, impairment is measured based on the fair value of the collateral, less its estimated cost to sell. The amount of the allowance is equal to the difference between the loan’s impaired value and the recorded investment. The Company maintains a general credit loss allowance for receivables from dealers based on risk ratings and individually evaluates loans for specific impairment as necessary. As of December 31, 2019 and 2018, the credit loss allowance for receivables from dealers is comprised entirely of general allowance as none of these receivables have been determined to be individually impaired. The activity in the credit loss allowance for retail installment contracts and Dealer Loans for the years ended December 31, 2019 and 2018 was as follows: Year Ended December 31, 2019 Retail Installment Contracts Receivables from Dealers Personal Loans Non-TDR TDR Balance — beginning of year $ 1,819,360 $ 1,416,743 $ 153 $ 761 Provision for credit losses 1,774,000 317,305 (21) 1,096 Charge-offs (a) (3,636,924) (1,559,318) — (2,107) Recoveries 2,167,442 739,988 — 250 Balance — end of year $ 2,123,878 $ 914,718 $ 132 $ — Year Ended December 31, 2018 Retail Installment Contracts Receivables Personal Loans Non-TDR TDR Balance — beginning of year $ 1,540,315 $ 1,804,132 $ 164 $ 2,565 Provision for credit losses 1,433,977 772,448 (11) (188) Charge-offs (a) (2,850,361) (2,029,325) — (2,546) Recoveries 1,695,429 869,488 — 930 Balance — end of year $ 1,819,360 $ 1,416,743 $ 153 $ 761 Year Ended December 31, 2017 Retail Installment Contracts Receivables Personal Loans Non-TDR TDR Balance — beginning of year $ 1,799,760 $ 1,611,295 $ 724 $ — Provision for credit losses 877,771 1,475,861 (560) 10,691 Charge-offs (a) (2,758,023) (2,064,331) — (8,945) Recoveries 1,620,807 781,307 — 819 Balance — end of year $ 1,540,315 $ 1,804,132 $ 164 $ 2,565 (a) 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 credit loss allowance on these loans. The Company estimates losses on the finance lease receivable portfolio based on delinquency status and loss experience to date, as well as various economic factors. The activity in the lease loss allowance for finance leases for the years ended December 31, 2019, 2018 and 2017 was as follows: For the Year Ended December 31, 2019 2018 2017 Balance — beginning of year $ 3,359 $ 5,642 $ 9,988 Provision for lease losses 2,151 (641) 48 Charge-offs (4,185) (6,545) (11,069) Recoveries 3,416 4,903 6,675 Balance — end of year $ 4,741 $ 3,359 $ 5,642 There was no impairment activity noted for purchased receivable portfolio - credit impaired for the years ended December 31, 2019, 2018 and 2017. 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. 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. 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 $128,872 and $129,227 as of December 31, 2019 and 2018, respectively. A summary of delinquencies as of December 31, 2019 and 2018 is as follows: December 31, 2019 Finance Receivables Held for Investment Retail Installment Contract Loans Purchased Receivables Portfolios - credit impaired Total Percent (b) Principal, 30-59 days past due $ 2,972,495 $ 1,930 $ 2,974,425 9.7 % Delinquent principal over 59 days (a) 1,578,452 1,596 1,580,048 5.1 % Total delinquent principal $ 4,550,947 $ 3,526 $ 4,554,473 14.8 % December 31, 2018 Finance Receivables Held for Investment Retail Installment Contract Loans Purchased Receivables Portfolios - credit impaired Total Percent (b) Principal, 30-59 days past due $ 3,118,869 $ 2,926 $ 3,121,795 11.0 % Delinquent principal over 59 days (a) 1,712,243 1,532 1,713,775 6.0 % Total delinquent principal $ 4,831,112 $ 4,458 $ 4,835,570 17.0 % (a) Interest is generally accrued until 60 days past due in accordance with the Company’s accounting policy for retail installment contracts.

As of December 31, 2019 and 2018, there were no receivables from dealers that were 30 days or more delinquent. As of December 31, 2019 and 2018, there were zero retail installment contracts held for sale that were 30 days or more delinquent. Credit Quality Indicators FICO ® Distribution — A summary of the credit risk profile of the Company’s retail installment contracts held for investment by FICO ® distribution, determined at origination, as of December 31, 2019 and 2018 was as follows: FICO ® Band December 31, 2019 (b) December 31, 2018 (b) Commercial (a) 2.4% 1.9% No-FICO ® s 10.0% 11.0% <540 16.9% 19.8% 540-599 31.9% 32.9% 600-639 19.0% 18.2% >640 19.8% 16.2% (a) No FICO ® score is obtained on loans to commercial borrowers. (b) Percentages are based on unpaid principal balance. 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 as follows: Pass — Asset is well-protected by the current net worth and paying capacity of the obligor or guarantors, if any, or by the fair value less costs to sell any underlying collateral in a timely manner. Special Mention — Asset has potential weaknesses that deserve management’s close attention, which, if left uncorrected, may result in deterioration of the repayment prospects for an asset at some future date. Special Mention assets are not adversely classified. Substandard — Asset is inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. A well-defined weakness or weaknesses exist that jeopardize the liquidation of the debt. The loans are characterized by the distinct possibility that the Company will sustain some loss if deficiencies are not corrected. Doubtful — Exhibits the inherent weaknesses of a substandard credit. Additional characteristics exist that make collection or liquidation in full highly questionable and improbable, on the basis of currently known facts, conditions and values. Possibility of loss is extremely high, but because of certain important and reasonable specific pending factors which may work to the advantage and strengthening of the credit, an estimated loss cannot yet be determined. Loss — Credit is considered uncollectable and of such little value that it does not warrant consideration as an active asset. There may be some recovery or salvage value, but there is doubt as to whether, how much or when the recovery would occur. All the receivables from dealers, as of December 31, 2019 and December 31, 2018 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. Management considers TDRs to include all retail installment contracts that have been modified at least once, deferred for a period of 90 days or more, or deferred at least twice. Additionally, restructurings through bankruptcy proceedings are deemed to be TDRs. The purchased receivables portfolio - credit impaired, 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 December 31, 2019 and 2018 primarily consisted of loans that had been deferred or modified to receive a temporary reduction in monthly payment. As of December 31, 2019 and 2018, there were no receivables from dealers classified as a TDR. For loans not classified as TDRs, the Company generally estimates an appropriate allowance for credit losses based on delinquency status, the Company’s historical loss experience, estimated values of underlying collateral, and various economic factors. Once a loan has been classified as a TDR, it is generally assessed for impairment based on the present value of expected future cash flows discounted at the loan’s original effective interest rate considering all available evidence. For loans that are considered collateral-dependent, such as certain bankruptcy modifications, impairment is measured based on the fair value of the collateral, less its estimated cost to sell. A loan that has been classified as a TDR remains so until the loan is liquidated through payoff or charge-off. 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. 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 on the recorded investment, if not expected to be collected. The table below presents the Company’s TDRs as of December 31, 2019 and 2018: December 31, 2019 December 31, 2018 Retail Installment Contracts Outstanding recorded investment (a) $ 3,828,892 $ 5,365,477 Impairment (914,718) (1,416,743) Outstanding recorded investment, net of impairment $ 2,914,174 $ 3,948,734 (a) As of December 31, 2019, the outstanding recorded investment 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. As of December 31, 2018, the outstanding recorded investment excludes $90.1 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 Company’s delinquent TDRs at December 31, 2019 and 2018 is as follows: December 31, 2019 December 31, 2018 Retail Installment Contracts (a) Principal, 30-59 days past due $ 927,952 $ 1,265,946 Delinquent principal over 59 days 521,709 810,589 Total delinquent TDR principal $ 1,449,661 $ 2,076,535 (a) The balances in the above table reflect total unpaid principal balance rather than net recorded investment before allowance. Average recorded investment and interest income recognized on TDR loans are as follows: For the Year Ended December 31, 2019 2018 2017 Retail Installment Contracts Average outstanding recorded investment in TDRs $ 4,609,775 $ 5,970,789 $ 6,069,442 Interest income recognized 795,780 1,035,783 1,037,159 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 years ended December 31, 2019, 2018 and 2017: For the Year Ended December 31, 2019 2018 2017 Retail Installment Contracts Outstanding recorded investment before TDR $ 1,276,326 $ 2,226,775 $ 3,547,456 Outstanding recorded investment after TDR 1,280,025 2,236,262 3,541,968 Number of contracts (not in thousands) 74,545 132,633 204,775 A TDR is considered to have subsequently defaulted upon charge off, which for retail installment contracts 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 for the years ended December 31, 2019, 2018 and 2017 are summarized in the following table: For the Year Ended December 31, 2019 2018 2017 Retail Installment Contracts Recorded investment in TDRs that subsequently defaulted (a) $ 376,151 $ 682,348 $ 820,765 Number of contracts (not in thousands) 22,694 40,149 46,600 (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.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangibles	Goodwill and Intangibles The Company has identified one operating segment which is also the reporting unit, Consumer Finance. Management tests goodwill for impairment annually and in interim, if an event or circumstance occurs that would “more likely than not” reduce the fair value of the reporting unit to an amount below its carrying value. The Company determines if impairment exists by estimating the fair value of the Consumer Finance reporting unit using the market capitalization method at the measurement date and comparing it to the carrying value. If the fair value is greater than the carrying value, then no goodwill impairment has occurred. The Company completed its test of goodwill for impairment as of October 1, 2019 and concluded that goodwill was not impaired. The carrying amount of goodwill for the years ended December 31, 2019 and 2018, was unchanged at $74,056. For each of the years ended December 31, 2019, 2018 and 2017, goodwill amortization of $5,463, w as deductible for tax purposes.

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 consolidated balance sheets. The collateral, borrowings under credit facilities and securitization notes payable of the Company’s consolidated VIEs remain on the consolidated balance sheets. The Company recognizes finance charges, fee income, and provision for credit losses on the retail installment contracts, and leased vehicles and interest expense on the debt. Revolving credit facilities generally also utilize entities that are considered VIEs which are included on the consolidated balance sheets. The Company also uses a titling trust to originate and hold its leased vehicles and the associated leases, in order to facilitate the pledging of leases to financing facilities or the sale of leases to other parties without incurring the costs and administrative burden of retitling the leased vehicles. This titling trust is considered a VIE. On-balance sheet variable interest entities 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 December 31, 2019 and 2018, the Company was servicin g $27,253,573 and $27,193,924, respectively, of gross retail installment contracts that have been transferred to consolidated Trusts. The remainder of the Company’s retail installment contracts remain unpledged. A summary of the cash flows received from consolidated securitization trusts during the years ended December 31, 2019, 2018 and 2017, is as follows: For the Year Ended December 31, 2019 2018 2017 Assets securitized $ 22,286,033 $ 26,650,284 $ 18,442,793 Net proceeds from new securitizations (a) $ 17,199,821 $ 17,338,880 $ 14,126,211 Net proceeds from retained bonds 251,602 1,059,694 499,354 Cash received for servicing fees (b) 990,612 887,988 866,210 Net distributions from Trusts (b) 3,615,461 2,767,509 2,613,032 Total cash received from Trusts $ 22,057,496 $ 22,054,071 $ 18,104,807 (a) Includes additional advances on existing securitizations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Company manages its exposure to changing interest rates using derivative financial instruments. In certain circumstances, the Company is required to hedge its interest rate risk on its secured structured financings and the borrowings under its revolving credit facilities. The Company uses interest rate swaps to counteract the variability of cash flows on securities issued by securitization Trusts and borrowings under the Company’s Warehouse facilities. The Company uses interest rate caps to satisfy the lending requirements to hedge its interest rate risk on secured structured financings. Certain of the Company’s interest rate swap agreements are designated as cash flow hedges for accounting purposes. Changes in the fair value of derivatives designated as cash flow hedges are recorded as a component of accumulated other comprehensive income (AOCI) and amounts are reclassified from AOCI to earnings as the forecasted transactions impact earnings. The Company’s remaining interest rate swap agreements, as well as its interest rate cap agreements and the corresponding options written to offset the interest rate cap agreements were not designated as hedges for accounting purposes. Changes in the fair value and settlements of derivative instruments not designated as hedges for accounting purposes are reflected in earnings as a component of interest expense. The underlying notional amounts and aggregate fair values of these derivative financial instruments at December 31, 2019 and 2018, are as follows: December 31, 2019 Notional Fair Value Asset Liability Interest rate swap agreements designated as cash flow hedges $ 2,650,000 $ (36,321) $ 2,807 $ (39,128) Interest rate swap agreements not designated as hedges 1,281,000 (10,267) — (10,267) Interest rate cap agreements 9,379,720 62,552 62,552 — Options for interest rate cap agreements 9,379,720 (62,552) — (62,552) December 31, 2018 Notional Fair Value Asset Liability Interest rate swap agreements designated as cash flow hedges $ 3,933,500 $ 36,489 $ 43,967 $ (7,478) Interest rate swap agreements not designated as hedges 2,270,200 9,423 11,553 (2,130) Interest rate cap agreements 7,741,765 128,377 128,377 — Options for interest rate cap agreements 7,741,765 (128,377) — (128,377) The aggregate fair value of the interest rate swap agreements was included on the Company’s 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 consolidated balance sheets. See Note 15 - “ Fair Value of Financial Instruments ” in the accompanying 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 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 December 31, 2019 and 2018: Gross Amounts Not Offset in the Assets Presented Collateral Net 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 December 31, 2018 Interest rate swaps - third party (b) $ 55,520 $ (23,929) $ 31,591 Interest rate caps - third party 128,377 (72,830) 55,547 Total derivatives subject to a master netting arrangement or similar arrangement 183,897 (96,759) 87,138 Total derivatives not subject to a master netting arrangement or similar arrangement — — — Total derivative assets $ 183,897 $ (96,759) $ 87,138 Total financial assets $ 183,897 $ (96,759) $ 87,138 (a) Collateral received includes cash, cash equivalents, and other financial instruments.

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: December 31, 2019 Operating leases-right of use assets $ 57,508 Other liabilities 78,938 Weighted average lease term 6.2 years Weighted average discount rate 3.4% Lease expense i ncurred totaled $13,837, $10,192 and $10,901 for the year ended December 31, 2019, 2018 and 2017, respectively, 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 straight-line basis over the lease term. Cash paid for amounts included in the measurement of operating lease liabilities was $16,788 during the year ended December 31, 2019. The maturity of lease liabilities at December 31, 2019 are as follows: 2020 $ 16,715 2021 13,201 2022 12,555 2023 12,678 2024 12,701 Thereafter 19,691 Total $ 87,541 Less: Interest (8,603) Present value of lease liabilities $ 78,938 The remaining obligations under lease commitments required under operating leases as of December 31, 2018, prior to the date of adoption and as defined by the previous lease accounting guidance, with noncancellable lease terms at December 31, 2018 were as follows: 2019 $ 12,817 2020 13,080 2021 12,940 2022 12,282 2023 12,393 Thereafter 32,270 Total $ 95,782 Available-for-sale debt securities Debt securities expected to be held for an indefinite period of time are classified as available-for-sale (“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. Realized gains and losses on sales of investment securities are recognized on the trade date and are determined using specific identification method and is 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.

Income Taxes

Income Taxes	12 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The components of the provision for income taxes for the years ended December 31, 2019, 2018 and 2017, were as follows: For the Year Ended December 31, 2019 2018 2017 Income before income taxes: Domestic $ 1,352,944 $ 1,189,612 $ 697,991 Foreign 1,324 2,656 106,018 Total $ 1,354,268 $ 1,192,268 $ 804,009 Current income tax expense (benefit): Federal $ 12,721 $ (9,702) $ (6,140) State 23,006 18,448 (6,436) Foreign 5 110 4,273 Total current income tax expense (benefit) $ 35,732 $ 8,856 $ (8,303) Deferred income tax expense (benefit): Federal 265,021 217,309 (390,637) State 59,138 50,180 30,181 Foreign 7 (3) (39) Total deferred income tax expense (benefit) 324,166 267,486 (360,495) Total income tax expense (benefit) $ 359,898 $ 276,342 $ (368,798) In December 2015, the Company formed a wholly-owned foreign subsidiary that is licensed in Puerto Rico as an International Financial Entity (IFE) under the Government approved Act Number 273. This classification resulted in the granting of a tax decree securing a 4% fixed income tax rate and a number of non-income tax benefits for an initial period of fifteen years. In March 2019, the Puerto Rico subsidiary was granted a tax decree pursuant to Act 20-2012 (the "Export Services Act"), effective as of January 1, 2019. This grant secures a 4% fixed income tax rate and a number of non-income tax benefits for an initial period of twenty years. Additionally, the grant under the Export Services Act cancels the grant under the IFE Act effective after December 31,2018. As of December 31, 2019 and 2018, the Company ha s no earnings which are considered indefinitely reinvested. The reconciliation of the federal statutory income tax rate to the Company’s effective income tax rates for the years ended December 31, 2019, 2018 and 2017, is as follows: For the Year Ended December 31, 2019 2018 2017 Federal statutory rate 21.0 % 21.0 % 35.0 % State and local income taxes — net of federal income tax benefit 4.7 4.6 2.3 Valuation allowance 0.1 0.3 — Electric vehicle credit (0.3) (0.8) (3.0) Tax reform - deferred impact — — (83.9) Tax reform - transition tax — — 3.1 Other 1.1 (1.9) 0.6 Effective income tax rate 26.6 % 23.2 % (45.9) % On December 22, 2017, H.R.1, known as the “Tax Cuts and Jobs Act,” was signed into law. The Tax Cuts and Jobs Act permanently lowered the corporate tax rate from the previous rate of 35% to 21%, effective for tax years beginning January 1, 2018. As a result of the reduction of the corporate tax rate, GAAP requires companies to revalue their deferred tax assets and liabilities with resulting tax effects accounted for in the reporting period of enactment. The Company recorded a one-time $674,886 benefit primarily due to the revaluation of its U.S. deferred tax liabilities at the lower 21% U.S. federal corporate income tax rate. The Tax Cuts and Jobs Act also created a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of U.S. subsidiaries. The Company recorded a $25,143 expense related to its Puerto Rican subsidiary, SCI. The Company’s accounting for the effects of the change in tax law is complete. The Tax Cuts and Jobs Act also requires a U.S. shareholder of a controlled foreign corporation (CFC) to include in income, as a deemed dividend, the global intangible low-taxed income (GILTI) of the CFC. This provision is effective for taxable years of foreign corporations beginning after December 31, 2017, and to taxable years of United States shareholders in which or with which such taxable years of foreign corporations end. The Company has elected to treat taxes due on future U.S. inclusions in taxable income under the GILTI provision as a current period expense when incurred. During the year ended December 31, 2018, the Company adopted ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This standard requires entities to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. The company reclassified $6,149 related to stranded tax effects for the year ended December 31, 2018. 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. Under the hypothetical separate company method, SC recorded a net impact of deemed affiliate activity in the amount of $(14,381), which is included in additional paid-in capital section in the accompanying consolidated balance sheets. At December 31, 2019 and 2018, the Company had a net receivable from affiliates under the tax sharing agreement of $11,010 and $734, respectively, which was included in related party taxes receivable in the consolidated balance sheet. The tax effects of temporary differences between the financial reporting and income tax basis of assets and liabilities at December 31, 2019 and 2018, are as follows: December 31, 2019 December 31, 2018 Deferred tax assets: Debt issuance costs $ 6,177 $ 5,454 Receivables 169,224 296,145 Derivatives 5,403 — Capitalized origination costs 12,142 196 Net operating loss carryforwards 1,889,557 1,468,374 Equity-based compensation 17,334 14,727 Credit carryforwards 183,221 177,526 Other 53,466 31,392 Total gross deferred tax assets 2,336,524 1,993,814 Deferred tax liabilities: Capitalized origination costs — — Goodwill (14,072) (12,735) Leased vehicles (3,752,794) (3,109,118) Furniture and equipment (14,192) (5,702) Derivatives — (13,357) Other (15,103) (1,275) Total gross deferred tax liabilities (3,796,161) (3,142,187) Valuation allowance (8,585) (7,510) Net deferred tax asset (liability) $ (1,468,222) $ (1,155,883) At December 31, 2019 and 2018, the Company’s largest deferred tax liability was leased vehicles o f $3,752,794 and $3,109,118, respectively. The increase in this liability is primarily due to accelerated depreciation for tax purposes. The Company had a like-kind exchange program for the leased auto portfolio through December 31, 2017. Pursuant to the program, the Company disposed of vehicles and acquired replacement vehicles in a form whereby tax gains on disposal of eligible vehicles were deferred. To qualify for like-kind exchange treatment, the Company exchanged through a qualified intermediary eligible vehicles being disposed of with vehicles being acquired, allowing the Company to generally carryover the tax basis of the vehicles sold (“like-kind exchanges”). The program resulted in a material deferral of federal and state income taxes, and a decrease in cash taxes in periods when the Company was not in a net operating loss (NOL) position. As part of the program, the proceeds from the sale of eligible vehicles were restricted for the acquisition of replacement vehicles and other specified applications. The Tax Cuts and Jobs Act permanently eliminated the ability to exchange personal property after January 1, 2018, which resulted in the like-kind exchange program being discontinued in 2018. The Company began generating qualified plug-in electric vehicle credits in 2013; the credit carryforwards of $176,480 will begin expiring in 2034. The Company has foreign tax credit carryforwards of $6,664, which will expire in varying amounts through 2028. The Company has work opportunity tax credit carryforwards of $76, which will expire in varying amounts through 2039. At adoption of ASU 2016-09 on January 1, 2017, the cumulative-effect for previously unrecognized excess tax benefits totaled $26,552 net of tax, and was recognized, as an increase, through an adjustment in beginning retained earnings. On a prospective basis, the Company recorded excess tax deficiency/(windfall), ne t of tax of $(1,089), $(761) and $796 in the provision for income taxes rather than as an decrease/(increase) to additional paid-in capital for the years ended December 31, 2019, 2018 and 2017, respectively. At December 31, 2019, the Company has tax-effected federal net operating loss carryforwards of $1,828,329, which may be offset against future taxable income. If not utilized in future years, $390,174 of these carryforwards will expire in varying amounts through 2037. The remaining $1,438,155 of carryforwards do not expire. The Company has tax-effected state net operating loss carryforwards of $61,228, which may be used against futur e taxable income. If not utilized in future years, $53,506 of these carryforwards will expire in varying amounts through 2039. The remaining $7,723 of state carryforwards do not expire. As of December 31, 2019, the Company had recorded a valuation allowance for state tax net operating loss carryforwards and foreign tax credits for which it does not have a tax-planning strategy in place. A rollforward of the valuation allowance for the years ended December 31, 2019, 2018 and 2017 is as follows: For the Year Ended December 31, 2019 2018 2017 Valuation allowance, beginning of year $ 7,510 $ 3,299 $ 2,501 Provision (release) 1,075 4,211 798 Valuation allowance, end of year $ 8,585 $ 7,510 $ 3,299 A reconciliation of the beginning and ending balances of gross unrecognized tax benefits for each of the years ended December 31, 2019, 2018 and 2017 is as follows: For the Year Ended December 31, 2019 2018 2017 Gross unrecognized tax benefits balance, January 1 $ 15,965 $ 14,746 $ 16,736 Additions for tax positions taken in the current year — — — Additions for tax positions of prior years 12,674 1,608 473 Reductions for tax positions of prior years — (203) (589) Reductions as a result of a lapse of the applicable statute of limitations (1,069) (186) (1,874) Settlements — — — Gross unrecognized tax benefits balance, December 31 $ 27,570 $ 15,965 $ 14,746 At December 31, 2019, 2018 and 2017, there were $27,440, $15,836 and $14,615, respectively, of net unrecognized tax benefits that, if recognized, would affect the annual effective tax rate. Accrued interest and penalties associated with uncertain tax positions are recognized as a component of the income tax provision. Accrued interest and penalties of $451, $895, and $653 are included with the r elated tax liability line in the accompanying consolidated balance sheets as of December 31, 2019, 2018 and 2017, respectively. At December 31, 2019, the Company believes that it is reasonably possible that a portion of the balance of the gross unrecognized tax benefits could decrease to zero in the next twelve months due to ongoing activities with various taxing jurisdictions that the Company expects may give rise to settlements or the expiration of statute of limitations. The Company continually evaluates expiring statutes of limitations, audits, proposed settlements, changes in tax law, and new authoritative rulings. The Company is subject to examination by federal and state taxing authorities. Periods subsequent to December 31, 2010 are open for audit by the IRS. The SHUSA consolidated return, of which the Company is a part through December 31, 2011, is currently under IRS examination for 2011. The Company’s separate returns for 2012, 2013 and 2014 are also under IRS examination. Periods subsequent to December 31, 2008, are open for audit by various state taxing authorities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The following table summarizes liabilities recorded for commitments and contingencies as of December 31, 2019 and 2018, all of which are included in accounts payable and accrued expenses in the accompanying consolidated balance sheets: Agreement or Legal Matter Commitment or Contingency December 31, 2019 December 31, 2018 Chrysler Agreement Revenue-sharing and gain/(loss), net-sharing payments $ 12,132 $ 7,001 Agreement with Bank of America Servicer performance fee 2,503 6,353 Agreement with CBP Loss-sharing payments 1,429 3,708 Other Contingencies Consumer arrangements 1,991 2,138 Legal and regulatory proceedings Aggregate legal and regulatory liabilities 137,000 97,700 Total commitments and contingencies $ 155,055 $ 116,900 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 $12,132 and $7,001 at December 31, 2019 and 2018, 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 $2,503 and $6,353 at December 31, 2019 and 2018, 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 $1,429 and $3,708 at December 31, 2019 and 2018, 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 $1,991 and $2,138 at December 31, 2019 and 2018, respectively, for other miscellaneous contingencies. Legal and regulatory proceedings Periodically, the Company is party to, or otherwise involved in, various lawsuits and other legal proceedings that arise in the ordinary course of business. In view of the inherent difficulty of predicting the outcome of any such lawsuit, regulatory matter and 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. 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 condition and results of operation. In accordance with applicable accounting guidance, the Company establishes an accrued liability for litigation, regulatory matters and other legal 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 litigation, regulatory matter or other legal 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. The Company continues to monitor the matter for further developments that could affect the amount of the accrued liability previously established. As of December 31, 2019, the Company has accrued aggregate legal and regulatory liabilities of $137 million. Further, the Company believes that the estimate of the aggregate range of reasonably possible losses, in excess of reserves established, for legal and regulatory proceedings is up to $11.5 million as of December 31, 2019. 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. In July 2017, the court entered an order staying the Deka Lawsuit pending the resolution of the appeal of a class certification order in In re Cobalt Int’l Energy, Inc. Sec. Litig., No. H-14-3428, 2017 U.S. Dist. LEXIS 91938 (S.D. Tex. June 15, 2017). In October 2018, the court vacated the order staying the Deka Lawsuit and ordered that merits discovery in the Deka Lawsuit be stayed until the court ruled on the issue of class certification. • Feldman Lawsuit: In October 2015, a shareholder derivative complaint was filed in the Court of Chancery of the State of Delaware, captioned Feldman v. Jason A. Kulas, et al ., C.A. No. 11614 (the "Feldman Lawsuit"). The Feldman Lawsuit names as defendants, certain of its 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. • Jackie888 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. # 12775 (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 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. On March 23, 2018, the Feldman Lawsuit and Jackie888 Lawsuit were consolidated under the caption In Re Santander Consumer USA Holdings, Inc. Derivative Litigation , Del. Ch., Consol. C.A. No. 11614-VCG. On January 21, 2020, the Company executed a Stipulation and Agreement of Settlement, Compromise and Release with the plaintiffs in the consolidated action that fully resolves all of the plaintiffs’ claims om the Feldman Lawsuit and the Jackie888 Lawsuit. The Stipulation provides for the settlement of the consolidated action in return for defendants causing the Company to enact and implement certain corporate governance reforms and enhancements. The settlement is subject to approval by the Court. Consumer Lending Cases The Company is also party to various lawsuits pending in federal and state courts alleging violations of state and federal consumer lending laws, including, without limitation, the Equal Credit Opportunity Act, the Fair Debt Collection Practices Act, Fair Credit Reporting Act, Section 5 of the Federal Trade Commission Act, the Telephone Consumer Protection Act, the Truth in Lending Act, wrongful repossession laws, usury laws and laws related to unfair and deceptive acts or practices.

Earnings Per Share [Abstract]
Computation of Basic and Diluted Earnings per Common Share	Computation of Basic and Diluted Earnings per Common Share Earnings per common share (“EPS”) is computed using the two-class method required for participating securities. Restricted stock awards are considered to be participating securities because holders of such shares have non-forfeitable dividend rights in the event of a declaration of a dividend on the Company’s common shares. The calculation of diluted EPS excludes the effect of exercise or settlement of the following securities that would be anti-dilutive: (a) Employee stock options of $24,507, $168,728 and $367,880 for the years ended December 31, 2019, 2018 and 2017, respectively; and (b) RSUs of zero for the years ended December 31, 2019 and 2018, and $626,551 for the year ended 2017. The following table represents EPS numbers for the years ended December 31, 2019, 2018 and 2017.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	12 Months Ended

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 for the asset or liability and are used to measure fair value to the extent relevant observable inputs are not available. 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 December 31, 2019 and 2018, and the level within the fair value hierarchy: December 31, 2019 Carrying Estimated Level 1 Level 2 Level 3 Assets: Cash and cash equivalents (a) $ 81,848 $ 81,848 $ 81,848 $ — $ — Finance receivables held for investment, net (b) 27,544,162 28,133,427 — 1,009,358 27,124,069 Restricted cash and cash equivalents (a) 2,079,239 2,079,239 2,079,239 — — Total $ 29,705,249 $ 30,294,514 $ 2,161,087 $ 1,009,358 $ 27,124,069 Liabilities: Notes payable — facilities with third parties (c) $ 5,399,931 $ 5,399,931 $ — $ — $ 5,399,931 Notes payable — secured structured financings (d) 28,141,885 28,360,948 — 18,646,326 9,714,622 Notes payable — facilities with Santander and related subsidiaries (e) 5,652,325 5,724,675 — — 5,724,675 Total $ 39,194,141 $ 39,485,554 $ — $ 18,646,326 $ 20,839,228 December 31, 2018 Carrying Estimated Level 1 Level 2 Level 3 Assets: Cash and cash equivalents (a) $ 148,436 $ 148,436 $ 148,436 $ — $ — Finance receivables held for investment, net (b) 24,914,833 26,037,559 — — 26,037,559 Restricted cash and cash equivalents (a) 2,102,048 2,102,048 2,102,048 — — Total $ 27,165,317 $ 28,288,043 $ 2,250,484 $ — $ 26,037,559 Liabilities: Notes payable — facilities with third parties (c) $ 4,478,214 $ 4,478,214 $ — $ — $ 4,478,214 Notes payable — secured structured financings (d) 26,901,530 26,994,912 — 17,924,867 9,070,045 Notes payable — facilities with Santander and related subsidiaries (e) 3,503,293 3,438,543 — — 3,438,543 Total $ 34,883,037 $ 34,911,669 $ — $ 17,924,867 $ 16,986,802 (a) Cash and cash equivalents and restricted cash and cash equivalents — The carrying amount of cash and cash equivalents, including restricted cash and cash equivalents, 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 are determined as follows: • Retail installment contracts held for investment and purchased receivables - credit impaired — The estimated fair value for certain finance receivables at December 31, 2019 is based on the most recent purchase price and hence has classified these amounts as Level 2. The estimated fair value for the remaining finance receivables is calculated based on a DCF in which the Company uses significant unobservable inputs on key assumptions, including historical default rates and adjustments to reflect prepayment rates, expected recovery rates, discount rates reflective of the cost of funding, and credit loss expectations.Accordingly, these remaining retail installment contracts held for investment 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) 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. (d) 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, including historical default rates, prepayment rates, discount rates reflective of the cost of funding, and credit loss expectations, which are considered level 3 inputs. (e) 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. 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 December 31, 2019 and 2018, and the level within the fair value hierarchy: Fair Value Measurements at December 31, 2019 Total Quoted Prices Significant Significant Other assets — trading interest rate caps (a) $ 37,222 $ — $ 37,222 $ — Due from affiliates — trading interest rate caps (a) 25,330 — 25,330 — Other assets — cash flow hedging interest rate swaps (a) 2,807 — 2,807 — Other assets — trading interest rate swaps (a) — — — — Other assets — available-for-sale-debt securities (b) 92,246 — 92,246 — Other liabilities — trading options for interest rate caps (a) 37,222 — 37,222 — Other liabilities — cash flow hedging interest rate swaps (a) 39,128 — 39,128 — Due to affiliates — trading options for interest rate caps (a) 25,330 — 25,330 — Other liabilities — trading interest rate swaps (a) 10,267 — 10,267 — Retail installment contracts (c)(d) 22,353 — 17,634 4,719 Fair Value Measurements at December 31, 2018 Total Quoted Prices Significant Significant Other assets — trading interest rate caps (a) $ 128,377 $ — $ 128,377 $ — Other assets — cash flow hedging interest rate swaps (a) 43,967 — 43,967 — Other assets — trading interest rate swaps (a) 11,553 — 11,553 — Other liabilities — trading options for interest rate caps (a) 128,377 — 128,377 — Other liabilities — cash flow hedging interest rate swaps (a) 7,478 — 7,478 — Other liabilities — trading interest rate swaps (a) 2,130 — 2,130 — Retail installment contracts (c)(d) 13,509 — — 13,509 (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 8). (b) The Company's available-for-sale 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 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. For a majority of these loans, the Company has used the most recent purchase price as the fair value and hence has classified these amounts as Level 2. The fair values of the remaining retail installment contracts are estimated using a DCF model. When estimating the fair value using this model, the Company uses significant unobservable inputs on key assumptions, which includes historical default rates and adjustments to reflect prepayment rates based on available data from a comparable market securitization of similar assets, discount rates reflective of the cost of funding of debt issuance and recent historical equity yields, and recovery rates based on the average severity utilizing reported severity rates and loss severity utilizing available market data from a comparable securitized pool. Accordingly, these remaining retail installment contracts held for investment are classified as Level 3. Changes in the fair value are recorded in investment gains (losses), net in the consolidated statement of income. (d) The aggregate fair value of retail installment contracts in non-accrual status as of December 31, 2019 and 2018 is $9,511 and $5,126, respectively. The following table presents the changes in retail installment contracts held for investment balances classified as Level 3 balances for the years ended December 31, 2019, 2018 and 2017: Year Ended 2019 2018 2017 Balance — beginning of year $ 13,509 $ 22,124 $ 24,495 Additions / issuances 2,079 6,631 21,672 Net collection activities (11,766) (16,755) (28,598) Gains recognized in earnings 897 1,509 4,555 Balance — end of year $ 4,719 $ 13,509 $ 22,124 The Company di d not have any transfers between Levels 1 and 2 during the years ended December 31, 2019, 2018 and 2017. There were no amounts transferred into or out of Level 3 during the years ended December 31, 2019, 2018 and 2017. 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 December 31, 2019 and 2018, and are categorized using the fair value hierarchy: Fair Value Measurements at December 31, 2019 Total Quoted Prices Significant Significant Lower of cost or fair value expense for the year ended December 31, 2019 Other assets — vehicles (a) $ 341,465 $ — $ 341,465 $ — $ — Personal loans held for sale (b) 1,007,105 — — 1,007,105 408,700 Auto loans impaired due to bankruptcy (c) 200,504 — 200,504 — 9,106 Fair Value Measurements at December 31, 2018 Total Quoted Prices Significant Significant Lower of cost or fair value expense for the year ended December 31, 2018 Other assets — vehicles (a) $ 342,097 $ — $ 342,097 $ — $ — Personal loans held for sale (b) 1,068,757 — — 1,068,757 367,219 Retail installment contracts held for sale — — — — 15,098 Auto loans impaired due to bankruptcy (c) 189,114 — 189,114 — 18,083 ( 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, including historical default rates and adjustments to reflect prepayment rates (principal and interest), discount rates reflective of the cost of funding, and credit loss expectations. 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. 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 December 31, 2019 and 2018: 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 Fair Value at December 31, 2018 Valuation Technique Unobservable Inputs Range Financial Assets: Retail installment contracts held for investment $ 13,509 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 $ 1,068,757 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%

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, including certain Trusts, which are considered VIEs. The Company also consolidates other VIEs for which it was deemed to be the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and the disclosures of contingent assets and liabilities, as of the date of the financial statements and the amount of revenue and expenses during the reporting periods. Actual results could differ from those estimates and those differences may be material. These estimates include the determination of credit loss allowance, discount accretion, impairment, fair value, 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 potentially show significant variances over time.
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.
Finance Receivables	Finance Receivables Finance receivables are comprised of retail installment contracts, purchased receivables - credit impaired, receivables from dealer, personal loans, and finance lease receivables. Finance receivables are classified as either held for sale or held for investment, depending on the Company’s intent and ability to hold the underlying contract for the foreseeable
Financing Receivable, Held-for-investment	Retail Installment Contracts Retail installment contracts consist largely of nonprime automobile finance receivables, which are acquired from dealers at a nonrefundable discount from the contractual principal amount. Retail installment contracts also include receivables originated through a direct lending program and loan portfolios purchased from other lenders. Retail installment contracts are primarily classified as held for investment and carried at amortized cost, net of allowance for credit losses. The Company has elected the fair value option for certain non-performing loans acquired through the exercise of a clean-up call. Accordingly, changes in the fair value of these finance receivables, which are based upon fair value estimates (Note 15), are reported in investment gains (losses), net, in the consolidated statements of income and comprehensive income. Interest is accrued when earned in accordance with the terms of the retail installment contract. The accrual of interest is discontinued and reversed once a retail installment contract becomes more than 60 days past due, and is resumed and reinstated if a delinquent account subsequently becomes 60 days or less past due. For loans on nonaccrual status, interest income is recognized on a cash basis. 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. Payments generally are applied to interest first, then principal, then fees, regardless of a contract’s accrual status. The payment following the partial payment must be a full payment, or the account will move into delinquency status at that time. Personal Loans, Net Personal loans, net, consists of revolving finance receivables acquired individually under terms of the Company’s agreements with certain third parties who originate and continue to service the loans. Interest is accrued when earned in accordance with the terms of the contract. The accrual of interest on revolving personal loans continues until the receivable becomes 180 days past due, at which point the principal amount and interest are charged off. Receivables from Dealers Receivables from dealers include Floorplan Loans provided to dealerships to finance new and used vehicles for their inventory. Receivables from dealers also include real estate loans and working capital revolving lines of credit. Interest on these loans is accrued when earned in accordance with the agreement with the dealer.
Purchased Receivable Portfolios	Purchased Receivables Portfolios - Receivables portfolios purchased from other lenders or pursuant to a repurchase obligation that are purchased at amounts less than the principal amount of those receivables, resulting in a discount to par, are accounted for in accordance with ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality , if the discount was attributable, at least in part, to the expectation that not all contractual cash flows will be received from borrowers, which did not exist at the origination of the loans. The excess of the estimated undiscounted principal, interest, and other cash flows expected to be collected over the initial investment in the acquired loans, or accretable yield, is accreted to interest income over the expected life of the loans using the effective interest rate method. The nonaccretable difference is the excess between the contractually required payments and the amount of cash flows, considering the impact of prepayments, expected to be collected. The nonaccretable difference is not accreted into income. Any deterioration in the performance of the purchased portfolios results in an incremental impairment. Improvements in performance of the purchased pools that significantly increase actual or expected cash flows result in first a reversal of previously recorded impairment and then in a transfer of the excess from nonaccretable difference to accretable yield, which will be recorded as finance income over the remaining life of the receivables. Receivable portfolios purchased from other lenders are considered non-credit impaired loans if they either do not have evidence of credit quality deterioration or it was not probable that the Company would not collect all contractually required payments, which will be evaluated using a number of factors including the loan’s delinquency status, borrower’s credit status, and roll rates. Accordingly, these loans will be accounted for in accordance with ASC 310 - 20. Under ASC 310-20, the difference between the loan’s principal balance, at the time of purchase, and the fair value is recognized as an adjustment of yield over the life of the loan. All other policies related to interest income,
Financing Receivables Held for Sale, Net	Finance Receivables Held for Sale, Net Finance receivables, which may include any of the receivables described above, that the Company does not have the intent and ability to hold for the foreseeable future or until maturity or payoff, including those previously designated as held for investment and subsequently identified for sale, are classified as held for sale, at origination or at the time a decision to sell is made. Finance receivables designated as held for sale are carried at the lower of cost or market, as determined on an aggregate basis. Cost, or recorded investment, includes deferred net origination fees and costs, premium or discounts, accrued interest, manufacturer subvention (if any) and any direct write-down of the investment. When loans are transferred from held for investment, the Company records charge offs as per its charge off policy. Any excess allowance is reversed through provision expense. Subsequent to the initial measurement of retail installment contracts and personal loans held for sale, market declines in the recorded investment, whether due to credit or market risk, are recorded through investment gains (losses), net of lower of cost or market adjustments.
Provision for Credit Losses	Provision for Credit Losses Provisions for credit losses are charged to operations in amounts sufficient to support the credit loss allowance in accordance with the Company’s estimate. The Company estimates an allowance on retail installment contracts and personal loans held for investment not classified as TDRs at a level considered adequate to cover expected net credit losses inherent in the recorded investment of that portfolio. Probable losses are estimated based on contractual delinquency status and historical loss experience, in addition to the Company’s judgment of estimates of the value of the underlying collateral, changes in the used vehicle value index, delinquency status, historical collection rates and other information in order to make the necessary judgments as to probable loan losses. For loans classified as TDRs, impairment is generally measured based on the present value of expected future cash flows discounted at the original effective interest rate. For loans that are considered collateral-dependent, such as certain bankruptcy modifications, impairment is measured based on the fair value of the collateral, less its estimated cost to sell. Provisions for credit losses are also charged to operations for impairment on TDRs. Retail installment contracts are charged off against the allowance in the month in which the account becomes greater than 120 days contractually delinquent if the Company has not repossessed the related vehicle. The Company charges off accounts in repossession when the automobile is repossessed and legally available for disposition. A net charge-off represents the difference between the estimated sales proceeds and the Company’s recorded investment in the related contract. Costs to sell the vehicle are presented in repossession expense. Accounts in repossession that have been charged off and are pending liquidation are removed from retail installment contracts and the related repossessed automobiles are included in other assets in the Company’s consolidated balance sheets. In addition to maintaining a general allowance based on risk ratings, receivables from dealers are evaluated individually for impairment with allowances established for receivables determined to be individually impaired. Receivables from dealers are charged off against these allowances at the time that the credit is considered uncollectable and of such little value that it does not warrant consideration as an active asset.
Troubled Debt Restructurings	Troubled Debt Restructurings A modification of finance receivable terms is considered a troubled debt restructuring (TDR) if the Company grants a concession it would not otherwise have considered to a borrower for economic or legal reasons related to the debtor’s
Lessor, Leases	Leased Vehicles, Net (SC as Lessor) Most vehicles for which the Company is the lessor are classified as operating leases, as they do not meet the accounting requirements to be classified as a finance lease. The net capitalized cost of each lease is recorded as an asset and depreciated on a straight-line basis over the contractual term of the lease to the expected residual value. The expected residual value and, accordingly, the monthly depreciation expense may change throughout the term of the lease. The Company estimates expected residual values using independent data sources and internal statistical models that take into consideration economic conditions, current auction results, the Company’s remarketing abilities, and manufacturer vehicle and marketing programs. Over the life of the lease, the Company evaluates the adequacy of the estimate of the residual value and may make adjustments to the depreciation rates to the extent the expected value of the vehicle at lease termination changes. Lease payments due from customers are recorded as income until and unless a customer becomes more than 60 days delinquent, at which time the accrual of revenue is discontinued and reversed. The accrual is resumed and reinstated if a delinquent account subsequently becomes 60 days or less past due. Subvention payments from the manufacturer, down payments from the customer, and initial direct costs incurred in connection with originating the lease are treated as a reduction to the cost basis of the underlying lease asset and are amortized on a straight-line basis over the contractual term of the lease. The amortization of manufacturer subvention payments is reflected as a reduction to depreciation expense over the life of the contract. The Company periodically evaluates its investment in operating leases for impairment if circumstances, such as a systemic and material decline in used vehicle values, indicates that an impairment may exist. These circumstances could include, for example, shocks to oil and gas prices (which may have a pronounced impact on certain models of vehicles) or pervasive manufacturer defects (which may systemically affect the value of a particular vehicle brand or model). Impairment is determined to exist if fair value of the leased asset is less than carrying value and it is determined that the net carrying value is not recoverable. The net carrying value of a leased asset is not recoverable if it exceeds the sum of the undiscounted expected future cash flows expected to result from the lease payments and the estimated residual value upon eventual disposition. If our operating lease assets are considered to be impaired, the impairment is measured as the amount by which the carrying amount of the assets exceeds the fair value as estimated by discounted cash flows. No impairment was recognized in 2019, 2018, or 2017. Finance Lease Receivables, net (SC as Lessor) Leases classified as finance leases are accounted for as direct financing leases. Minimum lease payments plus the estimated residual value of the leased vehicle are recorded as the gross investment. The difference between the gross investment and the cost of the leased vehicle is recorded as unearned income. Direct financing leases are reported at the aggregate of gross investments, net of unearned income and allowance for lease losses. Income for direct financing leases is recognized using the effective interest method, which provides a constant periodic rate of return on the outstanding investment on the lease. Repossessed Vehicles and Repossession Expense Repossessed vehicles represent vehicles the Company has repossessed due to the borrowers’ default on the payment terms of the retail installment contracts, loans or leases. The Company generally begins repossession activity once a customer has reached 60 days past due. The customer has an opportunity to redeem the repossessed vehicle by paying all outstanding balances, including finance charges and fees. Any vehicles not redeemed are sold at auction. The Company records the vehicles currently in its inventory at the lower of cost or estimated fair value, net of estimated costs to sell (See Notes 9 and 15). Repossession expense includes the costs to repossess and sell vehicles obtained due to borrower default. These costs include transportation, storage, rekeying, condition reports, legal fees, the fees paid to repossession agents and auction fees. Sales of Finance Receivables and Leases The Company transfers retail installment contracts into newly formed Trusts, which then issue one or more classes of notes payable backed by the retail installment contracts. The Company’s continuing involvement with the credit facilities and Trusts are in the form of servicing loans held by the special purpose entities (SPEs) and, generally, through holding a residual interest in the SPE. These transactions are structured without recourse. The Trusts are considered VIEs under GAAP and are consolidated when the Company has: (a) power over the significant activities of the entity and (b) an obligation to absorb losses or the right to receive benefits from the VIE which are potentially significant to the VIE. The Company has power over the significant activities of those Trusts as servicer of the financial assets held in the Trust. Servicing fees are not considered significant variable interests in the Trusts; however, when the Company also retains a residual interest in the Trust, either in the form of a debt security or equity interest, the Company has an obligation to absorb losses or the right to receive benefits that are potentially significant to the SPE. For all VIEs in which the Company is involved, the Company assesses whether it is the primary beneficiary of the VIE on an ongoing basis. In circumstances where the Company have both the power to direct the activities that most significantly impact the VIEs performance and the obligation to absorb losses or the right to receive benefits of the VIE that could be significant, the Company would conclude that it is the primary beneficiary of the VIE, and accordingly, these Trusts are consolidated within the consolidated financial statements, and the associated retail installment contracts, borrowings under credit facilities and securitization notes payable remain on the consolidated balance sheets. In situations where the Company is not deemed to be the primary beneficiary of the VIE, the Company does not consolidate the VIE and only recognizes its interests in the VIE. These securitizations involving Trusts are treated as sales of the associated retail installment contracts. While these Trusts are included in the consolidated financial statements, these Trusts are separate legal entities; thus, the finance receivables and other assets sold to these Trusts are legally owned by these Trusts, are available only to satisfy the notes payable related to the securitized retail installment contracts, and are not available to the Company’s creditors or other subsidiaries. The Company also sells retail installment contracts and leases to VIEs or directly to third parties, which the Company may determine meet sale accounting treatment in accordance with the applicable guidance. Due to the nature, purpose, and activity of these transactions, the Company either does not hold potentially significant variable interests or is not the primary beneficiary as a result of the Company’s limited further involvement with the financial assets. The transferred financial assets are removed from the Company’s consolidated balance sheets at the time the sale is completed. The Company generally remains the servicer of the financial assets and receives servicing fees. The Company also recognizes a gain or loss for the difference between the fair value, as measured based on sales proceeds plus (or minus) the value of any servicing asset (or liability) retained and carrying value of the assets sold. Operating Leases (SC as Lessee) Operating lease ROU assets and liabilities are recognized based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate for a collateralized borrowing based on the duration of the lease term in determining the present value of lease payments. The lease term includes options to extend or terminate a lease when the Company considers it reasonably certain that such options will be exercised. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease expense for operating lease is recognized on a straight-line basis over the lease term.
Fees, commissions, and other	Fees, commissions, and other Fees, commissions, and other primarily include late fees, miscellaneous, and other income, and are generally recorded when there is no doubt as to the collectability of the related receivable.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company has maintained balances in various operating and money market accounts in excess of federally insured limits.
Restricted Cash	Restricted Cash Cash deposited to support securitization transactions, lockbox collections, and the related required reserve accounts is recorded in the Company’s consolidated balance sheet as restricted cash. Excess cash flows generated by the securitization trusts are added to the restricted cash reserve account, creating additional over-collateralization until the contractual securitization requirement has been reached. Once the targeted reserve requirement is satisfied, additional
Income Taxes	Income Taxes Income tax expense consists of income taxes currently payable and deferred income taxes computed using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. The deferred tax asset is subject to reduction by a valuation allowance in certain circumstances. This valuation allowance is recognized if it is more likely than not that some portion or all of the deferred tax asset will not be realized based on a review of available evidence. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company records the benefit of uncertain tax positions in the consolidated financial statements when such positions (1) meet a more-likely-than-not threshold, (2) are settled through negotiation or litigation, or (3) the statute of limitations for the taxing authority to examine the position has expired. Tax benefits associated with an uncertain tax position are derecognized in the period in which the more-likely-than-not recognition threshold is no longer satisfied.
Furniture and Equipment	Furniture and Equipment three
Goodwill and Intangibles	Goodwill and Intangibles Goodwill represents the excess of consideration paid over fair value of net assets acquired in business combinations. Intangibles represent intangible assets purchased or acquired through business combinations, including trade names and software development costs. Intangibles are amortized over their estimated useful lives. The Company tests goodwill for impairment annually in accordance with the provisions of ASC 350, Intangibles-Goodwill and Other
Derivative Financial Instruments	Derivative Financial Instruments Derivative financial instruments are recognized as either assets or liabilities in the consolidated balance sheets at fair value. The accounting for changes in the fair value of each derivative financial instrument depends on whether it has been designated and qualifies as a hedge for accounting purposes, as well as the type of hedging relationship identified. The Company does not use derivative instruments for trading or speculative purposes. Interest Rate Swap Agreements — The Company uses interest rate swaps to hedge the variability of cash flows on securities issued by securitization Trusts and borrowings under the Company’s warehouse facilities. Certain interest rate swap agreements are designated and qualify as cash flow hedges, and are highly effective in reducing exposure to interest rate risk from both an accounting and an economic perspective. At hedge inception and at least quarterly, the interest rate swap agreements designated as accounting hedges are assessed to determine their effectiveness in offsetting changes in the cash flows of the hedged items and whether those interest rate swap agreements may be expected to remain highly effective in future periods. The Company uses the hypothetical derivative method to assess hedge effectiveness of cash flow hedges on a prospective and retrospective basis. At December 31, 2019, all of the Company’s interest rate swap agreements designated as cash flow hedges are deemed to be effective hedges for accounting purposes. The changes in the fair value of the interest rate swaps qualifying as cash flow hedges are included as a component of other comprehensive income(loss), net of estimated income taxes, as an unrealized gain or loss on cash flow hedges. These unrealized gains or losses are recognized as adjustments to income over the same period in which cash flows from the related hedged item affect earnings. The Company discontinues hedge accounting prospectively when it is determined that an interest rate swap agreement has ceased to be effective as an accounting hedge or if the underlying hedged cash flow is no longer probable of occurring. The Company has also entered into interest rate swap agreements related to its securitization trusts and warehouse facilities that are not designated as hedges. These agreements are intended to reduce the risk of interest rate fluctuations. For the interest rate swap agreements not designated as hedges, any gains or losses are included in the Company’s earnings as a component of interest expense. Interest Rate Cap Agreements — The Company purchases interest rate cap agreements to limit floating rate exposures on securities issued in credit facilities. As part of the interest rate risk management strategy, and when economically feasible, the Company may simultaneously sell a corresponding written option to offset the premium paid to purchase the interest rate cap agreement and thus retain the interest rate risk. Because these instruments entered into directly by the Company or through SPEs are not designated for hedge accounting, changes in the fair value of interest rate cap agreements purchased by the SPEs and written option sold by the Company are recorded in interest expenses on the consolidated statements of income and comprehensive income.
Stock-based Compensation	Stock-Based Compensation The Company measures the compensation cost of stock-based awards using the estimated fair value of those awards on the grant date, and recognizes the cost as expense over the vesting period of the awards (see Note 16).
Earnings per Share	Earnings per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised. It is computed after giving consideration to the weighted average dilutive effect of the Company’s stock options and restricted stock grants. Because the Company has issued participating securities in the form of unvested restricted stock that has dividend rights, the Company applies the two-class method when computing earnings per share.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Since January 1, 2019, the Company adopted the following FASB ASUs: • In February 2016, the FASB issued ASU 2016-02, Leases . The primary effect of the ASU is to replace the existing accounting requirements for operating leases for lessees. Lessee accounting requirements for finance leases and lessor accounting requirements for operating leases and sales type and direct financing leases (sales-type and direct financing leases were both previously referred to as capital leases) are largely unchanged. The Company adopted this standard using the modified retrospective method and utilized the optional transition method under which we continue to apply the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative period presented. For all our operating leases (primarily our office space/facility leases), where the Company is a lessee, adoption of the new standard resulted in recognizing on our balance sheet, a right-of-use (“ROU”) asset of $67,300, a reduction of accounts payable and accrued expenses of $24,100 relating to straight-line rent accruals and unamortized tenant improvement allowances, and a lease liability of $91,400. The right-of-use-asset and lease liability will be derecognized in a manner that effectively yields a straight-line lease expense over the lease term. In addition, the Company will no longer capitalize certain initial direct costs in connection with lease originations where it is the lessor. Further, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classification. We elected not to (a) use the hindsight practical expedient to determine the lease term for existing leases; and (b) recognize a lease liability and associated ROU asset for short term leases if such lease meet the definition under ASC 842. We chose not to elect the practical expedient to not separate non-lease components from lease components. The standard did not have a material impact on our consolidated statement of income or consolidated statement of cash flows. • In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted this standard effective January 1, 2019 and it did not have a material impact on the Company’s business, financial position or results of operations. The adoption of the following ASUs did not have a material impact on the Company’s business, financial position or results of operations. • ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities • ASU 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception • ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting • ASU 2018-16, Derivatives and Hedging (Topic 815), Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. • ASU 2018-09, Codification Improvements Recently Issued Accounting Pronouncements • In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This guidance significantly changes how entities will measure credit losses for most financial assets and certain other instruments that measured at amortized cost. The amendment introduces a new credit reserving framework known as "Current Expected Credit Loss" (“CECL”), which replaces the incurred loss impairment framework in current GAAP with one that reflects expected credit losses over the full expected life of financial assets and commitments, and requires consideration of a broader range of reasonable and supportable information, including estimation of future expected changes in macroeconomic conditions. Additionally, the standard changes the accounting framework for purchased credit deteriorated HTM debt securities and loans, and dictates measurement of AFS debt securities using an allowance instead of reducing the carrying amount as it is under the current OTTI framework. The Company adopted the new guidance on January 1, 2020. The Company established a cross-functional working group for implementation of this standard. Generally our implementation process included data sourcing and validation, development and validation of loss forecasting methodologies and models, including determining the length of the reasonable and supportable forecast period and selecting macroeconomic forecasting methodologies to comply with the new guidance, updating the design of our established governance, financial reporting, and internal control over financial reporting frameworks, and updating accounting policies and procedures. The status of our implementation was periodically presented to the Audit Committee and the Risk Committee. The Company completed multiple parallel model runs to test and refine its current expected credit loss models to satisfy the requirements of the new standard. The adoption of this standard resulted in the increase in the allowance for credit losses ("ACL") for loans of approximately $2 billion and a decrease to opening retained earnings, net of income taxes, at January 1, 2020. The estimated increase is based on forecasts of expected future economic conditions and is primarily driven by the fact that the allowance will cover expected credit losses over the full expected life of the loan portfolios. The standard did not have a material impact on the Company's other financial instruments. • In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurement , which modifies the disclosure requirements on fair value measurements. The ASU removes the requirement to disclose: the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level 3 fair value measurements. The ASU requires disclosure of changes in unrealized gains and losses for the period included in other comprehensive income (loss) for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The Company adopted the new guidance effective January 1, 2020 and it did not have a material impact on the Company’s business, financial position or results of operations. In addition to those described in detail above, the Company evaluated the ASU 2018-17, Consolidation (Topic 10): Targeted Improvements to Related Party Guidance for Variable Interest Entities, and it did not have a material impact on the Company’s business, financial position, results of operations or disclosures.

(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 are determined as follows: • Retail installment contracts held for investment and purchased receivables - credit impaired — The estimated fair value for certain finance receivables at December 31, 2019 is based on the most recent purchase price and hence has classified these amounts as Level 2. The estimated fair value for the remaining finance receivables is calculated based on a DCF in which the Company uses significant unobservable inputs on key assumptions, including historical default rates and adjustments to reflect prepayment rates, expected recovery rates, discount rates reflective of the cost of funding, and credit loss expectations.Accordingly, these remaining retail installment contracts held for investment 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) 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. (d) 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, including historical default rates, prepayment rates, discount rates reflective of the cost of funding, and credit loss expectations, which are considered level 3 inputs. (e) 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.
Assets and Liabilities 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 December 31, 2019 and 2018, and the level within the fair value hierarchy: Fair Value Measurements at December 31, 2019 Total Quoted Prices Significant Significant Other assets — trading interest rate caps (a) $ 37,222 $ — $ 37,222 $ — Due from affiliates — trading interest rate caps (a) 25,330 — 25,330 — Other assets — cash flow hedging interest rate swaps (a) 2,807 — 2,807 — Other assets — trading interest rate swaps (a) — — — — Other assets — available-for-sale-debt securities (b) 92,246 — 92,246 — Other liabilities — trading options for interest rate caps (a) 37,222 — 37,222 — Other liabilities — cash flow hedging interest rate swaps (a) 39,128 — 39,128 — Due to affiliates — trading options for interest rate caps (a) 25,330 — 25,330 — Other liabilities — trading interest rate swaps (a) 10,267 — 10,267 — Retail installment contracts (c)(d) 22,353 — 17,634 4,719 Fair Value Measurements at December 31, 2018 Total Quoted Prices Significant Significant Other assets — trading interest rate caps (a) $ 128,377 $ — $ 128,377 $ — Other assets — cash flow hedging interest rate swaps (a) 43,967 — 43,967 — Other assets — trading interest rate swaps (a) 11,553 — 11,553 — Other liabilities — trading options for interest rate caps (a) 128,377 — 128,377 — Other liabilities — cash flow hedging interest rate swaps (a) 7,478 — 7,478 — Other liabilities — trading interest rate swaps (a) 2,130 — 2,130 — Retail installment contracts (c)(d) 13,509 — — 13,509 (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 8). (b) The Company's available-for-sale 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 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. For a majority of these loans, the Company has used the most recent purchase price as the fair value and hence has classified these amounts as Level 2. The fair values of the remaining retail installment contracts are estimated using a DCF model. When estimating the fair value using this model, the Company uses significant unobservable inputs on key assumptions, which includes historical default rates and adjustments to reflect prepayment rates based on available data from a comparable market securitization of similar assets, discount rates reflective of the cost of funding of debt issuance and recent historical equity yields, and recovery rates based on the average severity utilizing reported severity rates and loss severity utilizing available market data from a comparable securitized pool. Accordingly, these remaining retail installment contracts held for investment are classified as Level 3. Changes in the fair value are recorded in investment gains (losses), net in the consolidated statement of income. (d) The aggregate fair value of retail installment contracts in non-accrual status as of December 31, 2019 and 2018 is $9,511 and $5,126, respectively.
Changes in Level 3 Balances, Assets	The following table presents the changes in retail installment contracts held for investment balances classified as Level 3 balances for the years ended December 31, 2019, 2018 and 2017: Year Ended 2019 2018 2017 Balance — beginning of year $ 13,509 $ 22,124 $ 24,495 Additions / issuances 2,079 6,631 21,672 Net collection activities (11,766) (16,755) (28,598) Gains recognized in earnings 897 1,509 4,555 Balance — end of year $ 4,719 $ 13,509 $ 22,124
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 December 31, 2019 and 2018, and are categorized using the fair value hierarchy: Fair Value Measurements at December 31, 2019 Total Quoted Prices Significant Significant Lower of cost or fair value expense for the year ended December 31, 2019 Other assets — vehicles (a) $ 341,465 $ — $ 341,465 $ — $ — Personal loans held for sale (b) 1,007,105 — — 1,007,105 408,700 Auto loans impaired due to bankruptcy (c) 200,504 — 200,504 — 9,106 Fair Value Measurements at December 31, 2018 Total Quoted Prices Significant Significant Lower of cost or fair value expense for the year ended December 31, 2018 Other assets — vehicles (a) $ 342,097 $ — $ 342,097 $ — $ — Personal loans held for sale (b) 1,068,757 — — 1,068,757 367,219 Retail installment contracts held for sale — — — — 15,098 Auto loans impaired due to bankruptcy (c) 189,114 — 189,114 — 18,083 ( 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, including historical default rates and adjustments to reflect prepayment rates (principal and interest), discount rates reflective of the cost of funding, and credit loss expectations. 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.
