Accounting Policies [Abstract]
BASIS OF PRESENTATION AND ACCOUNTING POLICIES	BASIS OF PRESENTATION AND ACCOUNTING POLICIES Introduction Santander Holdings USA, Inc. ("SHUSA" or the "Company") is the parent company (the "Parent Company") of Santander Bank, National Association (the "Bank" or "SBNA"), a national banking association; Santander Consumer USA Holdings Inc. (together with its subsidiaries, "SC"), a consumer finance company; Santander BanCorp (together with its subsidiaries, "Santander BanCorp"), a financial holding company headquartered in Puerto Rico that offers a full range of financial services through its wholly-owned banking subsidiary, Banco Santander Puerto Rico ("BSPR"); Santander Securities LLC ("SSLLC"), a broker-dealer headquartered in Boston, Massachusetts; Banco Santander International ("BSI"), an Edge corporation located in Miami, Florida that offers a full range of banking services to foreign individuals and corporations based primarily in Latin America; and Santander Investment Securities Inc. ("SIS"), a registered broker-dealer located in New York providing services in investment banking, institutional sales, and trading and offering research reports of Latin American and European equity and fixed income securities; as well as several other subsidiaries. SSLLC, SIS, and another SHUSA subsidiary, Santander Asset Management, LLC (“SAM”), are registered investment advisers with the Securities and Exchange Commission (the “SEC”). SHUSA is headquartered in Boston and the Bank's home office is in Wilmington, Delaware. SHUSA is a wholly-owned subsidiary of Banco Santander, S.A. ("Santander"). The Parent Company's two largest subsidiaries by asset size and revenue are the Bank and SC. The Bank’s primary business consists of attracting deposits and providing other retail banking services through its network of retail branches, and originating small business loans, middle market, large and global commercial loans, multifamily loans, residential mortgage loans, home equity lines of credit, and auto and other consumer loans throughout the Mid-Atlantic and Northeastern areas of the United States, focused throughout Pennsylvania, New Jersey, New York, New Hampshire, Massachusetts, Connecticut, Rhode Island, and Delaware. The Bank uses its deposits, as well as other financing sources, to fund its loan and investment portfolios. SC is a specialized consumer finance company focused on vehicle finance and third-party servicing and delivering superior service to dealers and customers across the full credit spectrum. SC's primary business is the indirect origination and servicing of retail installment contracts ("RICs") and leases, principally, through manufacturer-franchised dealers in connection with their sale of new and used vehicles to retail consumers. Additionally, SC sells consumer RICs through flow agreements and, when market conditions are favorable, it accesses the ABS market through securitizations of consumer RICs. In conjunction with a ten -year private label financing agreement with Fiat Chrysler Automobiles US LLC ("FCA") that became effective May 1, 2013 (the "Chrysler Agreement"), SC has operated as FCA's preferred provider for consumer loans, leases, and dealer loans and services to FCA customers and dealers under the Chrysler Capital brand. These products and services include consumer RICs and leases, as well as dealer loans for inventory, construction, real estate, working capital and revolving lines of credit. Refer to Note 16 for additional details. On June 28, 2019, SC 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 SC and FCA. SC also originates vehicle loans through a web-based direct lending program, purchases vehicle RICs from other lenders, and services automobile and recreational and marine vehicle portfolios for other lenders. Additionally, SC has other relationships through which it provides other consumer finance products. As of September 30, 2019 , SC was owned approximately 71.6% by SHUSA and 28.4% by other shareholders. SC Common Stock is listed on the New York Stock Exchange (the "NYSE") under the trading symbol "SC." During the third quarter of 2019, SBNA completed the sale of 14 bank branches and four automated teller machines ("ATMs") located in central Pennsylvania, together with approximately $471 million of deposits and $102 million of retail and business loans, to First Commonwealth Bank for a gain of $30.9 million . This transaction aligns with SHUSA’s strategy to reallocate capital to investments in core markets that will drive growth. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Intermediate Holding Company ("IHC") The enhanced prudential standards ("EPS") mandated by Section 165 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "DFA")(the “Final Rule") were enacted by the Federal Reserve to strengthen regulatory oversight of foreign banking organizations ("FBOs"). Under the Final Rule, FBOs with over $50 billion of U.S. non-branch assets, including Santander, were required to consolidate U.S. subsidiary activities under an IHC. Due to its U.S. non-branch total consolidated asset size, Santander is subject to the Final Rule. As a result of this rule, Santander transferred substantially all of its equity interests in U.S. bank and non-bank subsidiaries previously outside the Company to the Company, which became an IHC effective July 1, 2016. These subsidiaries included Santander BanCorp, BSI, SIS and SSLLC, as well as several other subsidiaries. On July 1, 2017, an additional Santander subsidiary, SFS, a finance company located in Puerto Rico, was transferred to the Company. Additionally, effective July 2, 2018, Santander transferred SAM to the IHC. The contribution of SAM to the Company transferred approximately $5.4 million of assets, $1.0 million of liabilities, and $4.4 million of equity to the Company. Although SAM is an entity under common control, its results of operations, financial condition, and cash flows are immaterial to the historical financial results of the Company. As a result, the Company elected to report the results of SAM on a prospective basis beginning July 2, 2018. As a result of the contribution of SAM, SHUSA's net income is understated by $1.0 million for the nine-month period ended September 30, 2018 . These amounts are immaterial to the overall presentation of the Company's financial statements for each of the periods presented. Basis of Presentation These Condensed Consolidated Financial Statements include accounts of the Company and its consolidated subsidiaries, and certain special purpose financing trusts that are considered VIEs. The Company generally consolidates VIEs for which it is deemed to be the primary beneficiary and voting interest entities ("VOEs") in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. These Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and pursuant to SEC regulations for interim financial information. Additionally, where applicable, the Company's accounting policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. In the opinion of management, the accompanying Condensed Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary for a fair statement of the Condensed Consolidated Balance Sheets , Statements of Operations , Statements of Comprehensive Income , Statements of Stockholder's Equity and Statements of Cash Flows ("SCF") for the periods indicated, and contain adequate disclosure of this interim financial information to make the information presented not misleading. These Condensed Consolidated Financial Statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2018 . Significant Accounting Policies 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. Management has identified (i) the allowance for loan losses and the reserve for unfunded lending commitments, (ii) estimates of expected residual values of leases vehicles subject to operating leases, (iii) accretion of discounts and subvention on RICs, (iv) goodwill, (v) fair value of financial instruments, and (vi) income taxes as the Company's significant accounting policies and estimates, in that they are important to the portrayal of the Company's financial condition, results of operations and cash flows and the accounting estimates related thereto require management's most difficult, subjective and complex judgments as a result of the need to make estimates about the effect of matters that are inherently uncertain. As of September 30, 2019 , with the exception of the items noted in the section captioned "Recently Adopted Accounting Standards" below, there have been no significant changes to the Company's accounting policies as disclosed in its Annual Report on Form 10-K for the year ended December 31, 2018 . NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Recently Adopted Accounting Standards Since January 1, 2019, the Company adopted the following Financial Accounting Standards Board ("FASB") Accounting Standards Updates (“ASUs"): • ASU 2016-02, Leases (Topic 842) . The Company adopted this standard as of January 1, 2019, resulting in the recognition of a right of-use (“ROU”) asset ( $664.1 million ) and lease liability ( $705.7 million ) in the Consolidated Balance Sheet for all operating leases with a term greater than 12 months. The Company adopted this ASU using the modified retrospective approach, with application at the adoption date and a cumulative-effect adjustment to the opening balance of retained earnings. Under this approach, comparative periods were not adjusted. We elected the package of practical expedients permitted under transition guidance, which allowed us to carry forward the historical lease classification. We also elected not to recognize a lease liability and associated ROU asset for short-term leases. We did not elect (1) the hindsight practical expedient when determining the lease term and (2) the practical expedient to not separate non-lease components from lease components. The ASU required the Company to accelerate the recognition of $18.7 million of previously deferred gains on sale-leaseback transactions, with such impact recorded to the opening balance of Retained earnings. The ROU asset and lease liability will subsequently be de-recognized in a manner that effectively yields a straight-line lease expense over the lease term. Lessee accounting requirements for finance leases (previously described as capital leases) and lessor accounting requirements for operating, sales-type, and direct financing leases (sales-type and direct financing leases were both previously referred to as capital leases) are largely unchanged. This standard did not materially affect our Consolidated Statements of Operations or SCF. • 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 capitalized costs will be presented with Other assets on the balance sheet, and the amortization expense will be presented in the Technology, outside service, and marketing expense line of the Statement of Operations. The Company has early adopted this standard effective January 1, 2019 and it did not have a material impact on the Company's Condensed Consolidated Financial Statements or related disclosures. The adoption of the following ASUs did not have a material impact on the Company's 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. Subsequent Events On October 21, 2019, the Company entered into an agreement to sell the stock of Santander BanCorp (the holding company that includes BSPR) for total consideration of approximately $1.1 billion , subject to adjustment based on the consolidated Santander BanCorp balance sheet at closing. At September 30, 2019, BSPR had 27 branches, approximately 1,000 employees, and total assets of approximately $6.2 billion . Among other conditions precedent to the closing, the transaction requires the Company to transfer all of BSPR's non-performing assets and the equity of SAM to the Company or one of its affiliates prior to closing. In addition, the transaction requires review and approval of various regulators, whose input is uncertain. Subject to satisfaction of the closing conditions, the transaction is expected to close in the middle of 2020. Completion of the transaction is not expected to result in any material gain or loss. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) The Company evaluated events from the date of the Condensed Consolidated Financial Statements on September 30, 2019 through the issuance of these Condensed Consolidated Financial Statements , and has determined that there have been no material events that would require recognition in its Condensed Consolidated Financial Statements or disclosure in the Notes to the Condensed Consolidated Financial Statements for the three-month and nine-month periods ended September 30, 2019 other than the events disclosed above, Note 4, and Note 10.

RECENT ACCOUNTING DEVELOPMENTS

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING DEVELOPMENTS	RECENT ACCOUNTING DEVELOPMENTS 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 are not measured at fair value through net income. 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 remaining 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. For AFS debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the OTTI framework. The standard also simplifies the accounting framework for purchased credit-impaired debt securities and loans. The Company will adopt the new guidance on January 1, 2020. The Company established a cross-functional working group for implementation of this standard. Our implementation process includes 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 frameworks, updating accounting policies and procedures, and determining future expanded disclosures on aspects such as credit quality. The status of our implementation is periodically presented to the Audit Committee and the Risk Committee. The Company continues to test and refine its CECL models to satisfy the requirements of the new standard. Oversight and testing, as well as efforts to meet expanded disclosure requirements, will extend through the remainder of 2019. The Company currently expects an increase in the allowance for credit losses ("ACL") for loans in the range of 55% to 70% and a decrease (net of tax) in our regulatory capital amounts and ratios. The Company expects to leverage relief provided by federal banking regulatory agencies for an initial capital decrease by phasing in the adoption over four years on a straight-line basis in its calculation of regulatory capital amounts and ratios. The Company does not expect a material impact on its other financial instruments. The increase in the ACL will be reflected as a decrease to opening retained earnings, net of income taxes, at January 1, 2020. The estimated increase will take into account 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. This estimate is subject to further refinement based on continuing reviews and approvals of models, methodologies and judgments. The impact at January 1, 2020 will depend upon the nature and characteristics of our financial instruments at the adoption date, the macroeconomic conditions and forecasts at that date, and other management judgments. 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 . This 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 timin g of transfers between levels, and the valuation processes for Level 3 fair value measurements. This ASU requires disclosure of changes in unrealized gains and losses for the period included in OCI (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. This new guidance will be effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the effect the new guidance will have on its Consolidated Financial Statements and related disclosures. In addition to those described in detail above, the Company is in the process of evaluating ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities , but does not expect it to have a material impact on the Company's financial position, results of operations, or disclosures.

An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. The OTTI assessment is a subjective process requiring the use of judgments and assumptions. During the securities-level assessments, consideration is given to (1) the intent not to sell and probability that the Company will not be required to sell the security before recovery of its cost basis to allow for any anticipated recovery in fair value, (2) the financial condition and near-term prospects of the issuer, as well as company news and current events, and (3) the ability to collect the future expected cash flows. Key assumptions utilized to forecast expected cash flows may include loss severity, expected cumulative loss percentage, cumulative loss percentage to date, weighted average Fair Isaac Corporation ("FICO ® ") scores and weighted average loan-to-value ("LTV") ratio, rating or scoring, credit ratings and market spreads, as applicable. The Company assesses and recognizes OTTI in accordance with applicable accounting standards. Under these standards, if the Company determines that impairment on its debt securities exists and it has made the decision to sell the security or it is more likely than not that the Company will be required to sell the security prior to recovery of its amortized cost basis, it recognizes the entire portion of the unrealized loss in earnings. If the Company has not made a decision to sell the security and it does not expect that it will be required to sell the security prior to the recovery of the amortized cost basis but the Company has determined that OTTI exists, it recognizes the credit-related portion of the decline in value of the security in earnings. NOTE 3. INVESTMENT SECURITIES (continued) The Company did no t record any OTTI related to its investment securities for the three-month and nine-month periods ended September 30, 2019 or 2018 . Management has concluded that the unrealized losses on its debt securities for which it has not recognized OTTI (which were comprised of 557 individual securities at September 30, 2019 ) are temporary in nature since (1) they reflect the increase in interest rates, which lowers the current fair value of the securities, (2) they are not related to the underlying credit quality of the issuers, (3) the entire contractual principal and interest due on these securities is currently expected to be recoverable, (4) the Company does not intend to sell these investments at a loss and (5) it is more likely than not that the Company will not be required to sell the investments before recovery of the amortized cost basis, which for the Company's debt securities may be at maturity. Accordingly, the Company has concluded that the impairment on these securities is not other than temporary. Gains (Losses) and Proceeds on Sales of Investment Securities Proceeds from sales of investments in debt securities and the realized gross gains and losses from those sales were as follows: Three-Month Period Nine-Month Period Ended September 30, (in thousands) 2019 2018 2019 2018 Proceeds from the sales of AFS securities $ 416,981 $ 987,352 $ 1,044,645 $ 1,026,798 Gross realized gains $ 2,667 $ 156 $ 6,007 $ 316 Gross realized losses (400 ) (1,844 ) (3,361 ) (2,247 ) OTTI — — — — Net realized gains/(losses) (1) $ 2,267 $ (1,688 ) $ 2,646 $ (1,931 ) (1) Includes net realized gain/(losses) on trading securities of $(0.3) million and $(0.6) million for the three-month and nine-month periods ended September 30, 2019 , respectively, and $(1.1) million and $(1.3) million for the three-month and nine-month periods ended September 30, 2018 , respectively. The Company uses the specific identification method to determine the cost of the securities sold and the gain or loss recognized. Other Investments Other Investments consisted of the following as of: (in thousands) September 30, 2019 December 31, 2018 FHLB of Pittsburgh and FRB stock $ 704,387 $ 631,239 Low Income Housing Tax Credit investments ("LIHTC") 247,407 163,113 Equity securities not held for trading 12,655 10,995 Trading securities 3,433 10 Total $ 967,882 $ 805,357 Other investments primarily include the Company's investment in the stock of the FHLB of Pittsburgh and the FRB. These stocks do not have readily determinable fair values because their ownership is restricted and they lack a market. The stocks can be sold back only at their par value of $100 per share, and FHLB stock can be sold back only to the FHLB or to another member institution. Accordingly, these stocks are carried at cost. During the three-month and nine-month periods ended September 30, 2019 , the Company purchased $87.8 million and $258.9 million of FHLB stock at par, respectively, and redeemed $89.5 million and $185.5 million of FHLB stock at par, respectively. There was no gain or loss associated with these redemptions. During the nine-month period ended September 30, 2019 , the Company did no t purchase FRB stock. The Company's LIHTC investments are accounted for using the proportional amortization method. Equity securities are measured at fair value as of September 30, 2019 , with changes in fair value recognized in net income, and consist primarily of Community Reinvestment Act (“CRA") mutual fund investments. With the exception of equity and trading securities which are measured at fair value, the Company evaluates these other investments for impairment based on the ultimate recoverability of the carrying value, rather than by recognizing temporary declines in value. The Company held an immaterial amount of equity securities without readily determinable fair values at the reporting date.

(2) Credit scores updated quarterly. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Consumer Lending Asset Quality Indicators-FICO and LTV Ratio For both residential and home equity loans, loss severity assumptions are incorporated in the loan and lease loss reserve models to estimate loan balances that will ultimately charge off. These assumptions are based on recent loss experience within various current LTV bands within these portfolios. LTVs are refreshed quarterly by applying Federal Housing Finance Agency Home price index changes at a state-by-state level to the last known appraised value of the property to estimate the current LTV. The Company's ALLL incorporates the refreshed LTV information to update the distribution of defaulted loans by LTV as well as the associated loss given default for each LTV band. Reappraisals on a recurring basis at the individual property level are not considered cost-effective or necessary; however, reappraisals are performed on certain higher risk accounts to support line management activities, default servicing decisions, or when other situations arise for which the Company believes the additional expense is warranted.

The Company maintains an ACL to provide for losses inherent in its portfolios. Certain loans are pledged as collateral for borrowings, securitizations, or special purpose entities ("SPEs"). These loans totaled $50.2 billion at September 30, 2019 and $49.5 billion at December 31, 2018 . Loans that the Company intends to sell are classified as LHFS. The LHFS portfolio balance at September 30, 2019 was $2.5 billion , compared to $1.3 billion at December 31, 2018 . LHFS in the residential mortgage portfolio that were originated with the intent to sell were $ 437.9 million as of September 30, 2019 and are reported at either estimated fair value (if the FVO is elected) or the lower of cost or fair value. For a discussion on the valuation of LHFS at fair value, see Note 14 to the Condensed Consolidated Financial Statements . Loans under SC’s personal lending platform have been classified as HFS and adjustments to lower of cost or market are recorded through Miscellaneous income, net on the Condensed Consolidated Statements of Operations . As of September 30, 2019 , the carrying value of the personal unsecured HFS portfolio was $1.0 billion . During the second quarter of 2019, the Company entered into an agreement to sell approximately $1.4 billion of performing residential loans to FNMA and approximately $566 million of this loan portfolio was sold during the second quarter for a gain of approximately $7 million . The remaining loans were sold during the third quarter of 2019 for an immaterial gain. In October 2019, SBNA agreed to sell from its portfolio certain restructured residential mortgage and home equity loans (with approximately $187 million of principal balances outstanding) to two unrelated third parties. This transaction is expected to settle in the fourth quarter with an immaterial impact on the Condensed Consolidated Statement of Operations. The loans will be sold with servicing released to the purchasers. This portfolio was classified as held for sale as of September 30, 2019 . On October 4, 2019, SBNA agreed to sell approximately $768 million of equipment finance loans and approximately $74 million of operating leases to an unrelated third party. This transaction is expected to settle in the fourth quarter with an immaterial gain on the sale. SBNA will not retain servicing of the assets. This portfolio was classified as held for sale as of September 30, 2019 . Interest on loans is credited to income as it is earned. Loan origination fees and certain direct loan origination costs are deferred and recognized as adjustments to interest income in the Condensed Consolidated Statements of Operations over the contractual life of the loan utilizing the interest method. Loan origination costs and fees and premiums and discounts on RICs are deferred and recognized in interest income over their estimated lives using estimated prepayment speeds, which are updated on a monthly basis. At September 30, 2019 and December 31, 2018 , accrued interest receivable on the Company's loans was $499.5 million and $524.0 million , respectively. NOTE 4.

These items resulted in a net increase in the loan balances of $1.7 billion and $1.4 billion as of September 30, 2019 and December 31, 2018 , respectively. (2) Other commercial includes commercial equipment vehicle financing ("CEVF") leveraged leases and loans. (3) Other consumer primarily includes recreational vehicle ("RV") and marine loans. (4) Beginning in 2018, the Bank has an agreement with SC by which SC provides the Bank with origination support services in connection with the processing, underwriting and purchase of RICs, primarily from Chrysler dealers. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Portfolio segments and classes GAAP requires that entities disclose information about the credit quality of their financing receivables at disaggregated levels, specifically defined as “portfolio segments” and “classes,” based on management’s systematic methodology for determining the ACL. The Company utilizes similar categorization compared to the financial statement categorization of loans to model and calculate the ACL and track the credit quality, delinquency and impairment status of the underlying loan populations. In disaggregating its financing receivables portfolio, the Company’s methodology begins with the commercial and consumer segments. The commercial segmentation reflects line of business distinctions. The CRE line of business includes C&I owner-occupied real estate and specialized lending for investment real estate. The Company's allowance methodology further classifies loans in this line of business into construction and non-construction loans; however, the methodology for development and determination of the allowance is generally consistent between the two portfolios. "C&I" includes non-real estate-related C&I loans. "Multifamily" represents loans for multifamily residential housing units. “Other commercial” includes loans to global customer relationships in Latin America which are not defined as commercial or consumer for regulatory purposes. The remainder of the portfolio primarily represents the CEVF portfolio. The Company's portfolio classes are substantially the same as its financial statement categorization of loans for consumer loan populations. “Residential mortgages” includes mortgages on residential property, including single family and 1-4 family units. "Home equity loans and lines of credit" include all organic home equity contracts and purchased home equity portfolios. "RICs and auto loans" includes the Company's direct automobile loan portfolios, but excludes RV and marine RICs. "Personal unsecured loans" includes personal revolving loans and credit cards. “Other consumer” includes an acquired portfolio of marine RICs and RV contracts as well as indirect auto loans. In accordance with the Company's accounting policy when establishing the collective ACL for originated loans, the Company's estimate of losses on recorded investment includes the estimate of the related net unaccreted discount balance that is expected at the time of charge-off, while it considers the entire unaccreted discount for loan portfolios purchased at a discount as available to absorb the credit losses when determining the ACL specific to these portfolios. This accounting policy is not applicable to the purchased loan portfolios acquired with evidence of credit deterioration, on which we elected to apply the FVO. The RIC and auto loan portfolio is comprised of: (1) RICs originated by SC prior to the first quarter 2014 consolidation and change in control of SC (the “Change in Control"), (2) RICs originated by SC after the Change in Control, and (3) auto loans originated by SBNA. The composition of the portfolio segment is as follows: (in thousands) September 30, 2019 December 31, 2018 RICs - Purchased HFI: Unpaid principal balance ("UPB") (1) $ 371,700 $ 844,582 UPB - FVO (2) 4,403 9,678 Total UPB 376,103 854,260 Purchase marks (3) (12,879 ) (51,125 ) Total RICs - Purchased HFI 363,224 803,135 RICs - Originated HFI: UPB (1) 28,528,963 27,049,875 Net discount (17,997 ) (135,489 ) Total RICs - Originated 28,510,966 26,914,386 SBNA auto loans 5,321,966 1,617,699 Total RICs - originated post-Change in Control 33,832,932 28,532,085 Total RICs and auto loans HFI $ 34,196,156 $ 29,335,220 (1) UPB does not include amounts related to the loan receivables - unsecured and loan receivables from dealers due to the short-term and revolving nature of these receivables.

(3) Includes purchase marks of $1.0 million and $2.1 million related to purchase loan portfolios on which we elected to apply the FVO at September 30, 2019 and December 31, 2018 , respectively.

Commercial Lending Asset Quality Indicators The Company's Risk Department performs a credit analysis and classifies certain loans over an internal threshold based on the commercial lending classifications described below: 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 acquire and 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. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) 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 uncollectible 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.

LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Consumer Lending Asset Quality Indicators-FICO and LTV Ratio For both residential and home equity loans, loss severity assumptions are incorporated in the loan and lease loss reserve models to estimate loan balances that will ultimately charge off. These assumptions are based on recent loss experience within various current LTV bands within these portfolios. LTVs are refreshed quarterly by applying Federal Housing Finance Agency Home price index changes at a state-by-state level to the last known appraised value of the property to estimate the current LTV. The Company's ALLL incorporates the refreshed LTV information to update the distribution of defaulted loans by LTV as well as the associated loss given default for each LTV band. Reappraisals on a recurring basis at the individual property level are not considered cost-effective or necessary; however, reappraisals are performed on certain higher risk accounts to support line management activities, default servicing decisions, or when other situations arise for which the Company believes the additional expense is warranted.

Variable Interest Entity and Securitizations [Abstract]
VIEs	VIEs The Company transfers RICs 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 its Condensed Consolidated Balance Sheets . The collateral borrowings under credit facilities and securitization notes payable of the Company’s consolidated VIEs remain on the Condensed Consolidated Financial Statements . The Company recognizes finance charges, fee income, and provisions for credit losses on the RICs, 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 Condensed Consolidated Balance Sheets . NOTE 6. VIEs (continued) 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 VIEs The assets of consolidated VIEs that are included in the Company's Condensed Consolidated Financial Statements , presented based upon the legal transfer of the underlying assets in order to reflect legal ownership, and that can be used only to settle obligations of the consolidated VIEs and the liabilities of those entities for which creditors (or beneficial interest holders) do not have recourse to the Company's general credit, were as follows (1) : (in thousands) September 30, 2019 December 31, 2018 Assets Restricted cash $ 1,702,681 $ 1,582,158 Loans (2) 25,084,477 24,098,638 Operating lease assets, net 16,037,817 13,978,855 Various other assets 592,890 685,383 Total Assets $ 43,417,865 $ 40,345,034 Liabilities Notes payable (2) $ 32,950,281 $ 31,949,839 Various other liabilities 179,474 122,010 Total Liabilities $ 33,129,755 $ 32,071,849 (1) Certain amounts shown above are greater than the amounts shown in the corresponding line items in the accompanying Condensed Consolidated Balance Sheets due to intercompany eliminations between the VIEs and other entities consolidated by the Company. For example, for most of its securitizations, the Company retains one or more of the lowest tranches of bonds. Rather than showing investment in bonds as an asset and the associated debt as a liability, these amounts are eliminated in consolidation as required by GAAP. (2) Reflects the impacts of purchase accounting. 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 Miscellaneous income, net. As of September 30, 2019 and December 31, 2018 , the Company was servicing $28.2 billion and $27.2 billion , respectively, of gross RICs that have been transferred to consolidated Trusts. The remainder of the Company’s RICs remains unpledged. A summary of the cash flows received from the consolidated securitization Trusts for the three-month and nine-month periods ended September 30, 2019 and 2018 is as follows: Three-Month Period Nine-Month Period Ended September 30, (in thousands) 2019 2018 2019 2018 Assets securitized $ 5,498,705 $ 5,414,393 $ 15,340,428 $ 19,167,290 Net proceeds from new securitizations (1) $ 4,475,722 $ 4,014,928 $ 12,232,777 $ 12,073,124 Net proceeds from sale of retained bonds 2,414 203,704 119,719 797,336 Cash received for servicing fees (2) 242,801 229,520 740,760 659,210 Net distributions from Trusts (2) 1,018,301 860,024 2,689,735 2,186,010 Total cash received from Trusts $ 5,739,238 $ 5,308,176 $ 15,782,991 $ 15,715,680 (1) Includes additional advances on existing securitizations. (2) These amounts are not reflected in the accompanying Consolidated SCF because the cash flows are between the VIEs and other entities included in the consolidation. Off-balance sheet VIEs During the three-month and nine-month periods ended September 30, 2019 , the Company sold no RICs to VIEs in off-balance sheet securitizations compared to sales of $274.6 million for a loss of $0.7 million and $2.9 billion for a loss of $20.7 million during the three-month and nine-month periods ended September 30, 2018 , respectively.

The Company made a change in its reportable segments beginning January 1, 2019 and, accordingly, has re-allocated goodwill to the related reporting units based on the estimated fair value of each reporting unit. Upon re-allocation, management tested the new reporting units for impairment, using the same methodology and assumptions as used in the October 1, 2018 goodwill impairment test, and noted there was no impairment. See Note 18 for additional details on the change in reportable segments. During first quarter of 2018, the reportable segments (and reporting units) formerly known as Commercial Banking and CRE were combined and presented as Commercial Banking. As a result, goodwill assigned to these former reporting units of $542.6 million and $870.4 million , for Commercial Banking and CRE, respectively, were combined. There were no disposals, additions or impairments of goodwill for the three-month and nine-month periods ended September 30, 2019 or 2018 . The Company evaluates goodwill for impairment at the reporting unit level. The Company completes its annual goodwill impairment test as of October 1 each year. The Company conducted its last annual goodwill impairment tests as of October 1, 2018 using generally accepted valuation methods. NOTE 7.

OTHER ASSETS (continued) Other assets is comprised of: • Operating lease ROU assets We have operating leases for real estate and non-real estate assets. Real estate leases relate to office space and bank/lending retail branches. Non-real estate leases include data centers, automated teller machines ("ATMs"), vehicles and certain equipment leases. 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. Some lease payments may vary based on changes in the Consumer Price Index. The Company generally uses the contractual lease terms to allocate lease and non-lease components. Real estate leases may include one or more options to renew, with renewal terms that can extend the lease term from one to five years or more. The exercise of lease renewal options is at our sole discretion. The Company includes a renewal option period in the lease term if it is reasonably certain that it will exercise such option. Certain leases also include options to purchase the leased property. 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. 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. Operating lease ROU assets and lease liabilities are recognized based on the present value of lease payments over the lease term, using our incremental borrowing rates. At September 30, 2019 , operating lease ROU assets were $663.2 million and operating lease liabilities were $721.4 million . Operating lease ROU assets are included in Other Assets in the Company’s Condensed Consolidated Balance Sheets. Lease liabilities are included in Accrued expenses and payables in the Company’s Condensed Consolidated Balance Sheets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES General Derivatives represent contracts between parties that usually require little or no initial net investment and result in one or both parties delivering cash or another type of asset to the other party based on a notional amount and an underlying asset, index, interest rate or future purchase commitment or option as specified in the contract. Derivative transactions are often measured in terms of notional amount, but this amount is generally not exchanged, is not recorded on the balance sheet, and does not represent the Company`s exposure to credit loss. The notional amount is the basis on which the financial obligation of each party to the derivative contract is calculated to determine required payments under the contract. The Company controls the credit risk of its derivative contracts through credit approvals, limits and monitoring procedures. The underlying asset is typically a referenced interest rate (commonly the overnight indexed swap (“OIS") rate or LIBOR), security, credit spread or index. The Company’s capital markets and mortgage banking activities are subject to price risk. The Company employs various tools to measure and manage price risk in its portfolios. In addition, the Board of Directors has established certain limits relative to positions and activities. The level of price risk exposure at any given time depends on the market environment and expectations of future price and market movements and will vary from period to period. See Note 14 for discussion of the valuation methodology for derivative instruments. Credit Risk Contingent Features The Company has entered into certain derivative contracts that require the posting of collateral to counterparties when those contracts are in a net liability position. The amount of collateral to be posted is based on the amount of the net liability and thresholds generally related to the Company's long-term senior unsecured credit ratings. In a limited number of instances, counterparties also have the right to terminate their International Swaps and Derivatives Association, Inc. ("ISDA") Master Agreements if the Company's ratings fall below a specified level, typically investment grade. As of September 30, 2019 , derivatives in this category had a fair value of $1.1 million . The credit ratings of the Company and the Bank are currently considered investment grade. During the third quarter of 2019 , no additional collateral would be required if there were a further 1 - or 2 - notch downgrade by either Standard & Poor's ("S&P") or Moody's Investor Services ("Moody's"). As of September 30, 2019 and December 31, 2018 , the aggregate fair value of all derivative contracts with credit risk contingent features (i.e., those containing collateral posting or termination provisions based on the Company's ratings) that were in a net liability position totaled $8.1 million and $9.5 million , respectively. The Company had $11.2 million and $11.5 million in cash and securities collateral posted to cover those positions as of September 30, 2019 and December 31, 2018 , respectively. Hedge Accounting Management uses derivative instruments designated as hedges to mitigate the impact of interest rate and foreign exchange rate movements on the fair value of certain assets and liabilities and on highly probable forecasted cash flows. These instruments primarily include interest rate swaps that have underlying interest rates based on key benchmark indices. The nature and volume of the derivative instruments used to manage interest rate risk depend on the level and type of assets and liabilities on the balance sheet and the risk management strategies for the current and anticipated interest rate environment. Interest rate swaps are generally used to convert fixed-rate assets and liabilities to variable rate assets and liabilities and vice versa. The Company utilizes interest rate swaps that have a high degree of correlation to the related financial instrument. Cash Flow Hedges The Company has outstanding interest rate swap agreements designed to hedge a portion of the Company’s floating rate assets and liabilities (including its borrowed funds). All of these swaps have been deemed highly effective cash flow hedges. The gain or loss on the derivative instrument is reported as a component of accumulated OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and is presented in the same Consolidated Statements of Operations line item as the earnings effect of the hedged item. The last of the hedges is scheduled to expire in March 2024 . The Company includes all components of each derivative's gain or loss in the assessment of hedge effectiveness. As of September 30, 2019 , the Company expected $5.4 million of losses recorded in accumulated other comprehensive loss to be reclassified to earnings during the subsequent twelve months as the future cash flows occur. NOTE 12. DERIVATIVES (continued) Derivatives Designated in Hedge Relationships – Notional and Fair Values Derivatives designated as accounting hedges at September 30, 2019 and December 31, 2018 included: (dollars in thousands) Notional Amount Asset Liability Weighted Average Receive Rate Weighted Average Pay Rate Weighted Average Life (Years) September 30, 2019 Cash flow hedges: Pay fixed — receive variable interest rate swaps $ 3,650,000 $ 5,886 $ 47,949 2.16 % 1.86 % 1.55 Pay variable - receive fixed interest rate swaps 6,320,000 16,666 20,067 1.43 % 1.82 % 2.42 Interest rate floor 4,000,000 27,205 — 0.02 % — % 1.47 Total $ 13,970,000 $ 49,757 $ 68,016 1.22 % 1.31 % 1.92 December 31, 2018 Cash flow hedges: Pay fixed — receive variable interest rate swaps $ 4,176,105 $ 44,054 $ 10,503 2.67 % 1.74 % 2.07 Pay variable - receive fixed interest rate swaps 4,000,000 — 89,769 1.41 % 2.40 % 2.02 Interest rate floor 2,000,000 10,932 — 0.04 % — % 1.91 Total $ 10,176,105 $ 54,986 $ 100,272 1.66 % 1.66 % 2.02 Other Derivative Activities The Company also enters into derivatives that are not designated as accounting hedges under GAAP. The majority of these derivatives are customer-related derivatives relating to foreign exchange and lending arrangements, as well as derivatives to hedge interest rate risk on SC's secured structured financings and the borrowings under its revolving credit facilities. SC uses both interest rate swaps and interest rate caps to satisfy these requirements and to hedge the variability of cash flows on securities issued by Trusts and borrowings under its warehouse facilities. In addition, derivatives are used to manage risks related to residential and commercial mortgage banking and investing activities. Although these derivatives are used to hedge risk and are considered economic hedges, they are not designated as accounting hedges because the contracts they are hedging are carried at fair value on the balance sheet, resulting in generally symmetrical accounting treatment for the hedging instrument and the hedged item. Mortgage Banking Derivatives The Company's derivatives portfolio includes mortgage banking interest rate lock commitments, forward sale commitments and interest rate swaps. As part of its overall business strategy, the Company originates fixed-rate and adjustable rate residential mortgages. It sells a portion of this production to the FHLMC, the FNMA, and private investors. The Company uses forward sales as a means of hedging against the economic impact of changes in interest rates on the mortgages that are originated for sale and on interest rate lock commitments. The Company typically retains the servicing rights related to residential mortgage loans that are sold. Most of the Company`s residential MSRs are accounted for at fair value. As deemed appropriate, the Company economically hedges MSRs using interest rate swaps and forward contracts to purchase MBS. Customer-related derivatives The Company offers derivatives to its customers in connection with their risk management needs and requirements. These financial derivative transactions primarily consist of interest rate swaps, caps, floors and foreign exchange contracts. Risk exposure from customer positions is managed through transactions with other dealers, including Santander. Other derivative activities The Company uses foreign exchange contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities. Foreign exchange contracts, which include spot and forward contracts as well as cross-currency swaps, represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date and may or may not be physically settled depending on the Company’s needs. Exposure to gains and losses on these contracts will increase or decrease over their respective lives as currency exchange and interest rates fluctuate. NOTE 12. DERIVATIVES (continued) Other derivative instruments primarily include forward contracts related to certain investment securities sales, an OIS, a total return swap on Visa, Inc. Class B common shares, and equity options, which manage the Company's market risk associated with certain investments and customer deposit products.

DERIVATIVES (continued) The net amount of change recognized in OCI for cash flow hedge derivatives were gains of $4.5 million and $16.2 million , net of tax, for the three-month and nine-month periods ended September 30, 2019 , respectively, and losses of $3.4 million and $26.4 million , net of tax, for the three-month and nine-month periods ended September 30, 2018 , respectively. The net amount of changes reclassified from OCI into earnings for cash flow hedge derivatives were losses of $3.7 million and $0.2 million , net of tax, for the three-month and nine-month periods ended September 30, 2019 , respectively, and a gain of $0.4 million and a loss of $10.1 million , net of tax, for the three-month and nine-month periods ended September 30, 2018 , respectively. Disclosures about Offsetting Assets and Liabilities The Company enters into legally enforceable master netting agreements, which reduce risk by permitting netting of transactions 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 and in a single currency. The right to offset and certain terms regarding the collateral process, such as valuation, credit events and settlement, are contained in the ISDA Master Agreement. The Company's financial instruments, including resell and repurchase agreements, securities lending arrangements, derivatives and cash collateral, may be eligible for offset on its Condensed Consolidated Balance Sheet s. The Company has elected to present derivative balances on a gross basis even if the derivative is subject to a legally enforceable nettable ISDA Master Agreement for all trades executed after April 1, 2013. Collateral that is received or pledged for these transactions is disclosed within the “Gross amounts not offset in the Condensed Consolidated Balance Sheets ” section of the tables below. Prior to April 1, 2013, the Company had elected to net all caps, floors, and interest rate swaps when it had an ISDA Master Agreement with the counterparty. The collateral received or pledged in connection with these transactions is disclosed within the “Gross amounts offset in the Condensed Consolidated Balance Sheets " section of the tables below. Information about financial assets and liabilities that are eligible for offset on the Condensed Consolidated Balance Sheets as of September 30, 2019 and December 31, 2018 , respectively, is presented in the following tables: Offsetting of Financial Assets Gross Amounts Not Offset in the Condensed Consolidated Balance Sheet (in thousands) Gross Amounts of Recognized Assets Gross Amounts Offset in the Condensed Consolidated Balance Sheet Net Amounts of Assets Presented in the Condensed Consolidated Balance Sheet Collateral Received (3) Net Amount September 30, 2019 Cash flow hedges $ 49,757 $ — $ 49,757 $ 17,070 $ 32,687 Other derivative activities (1) 661,443 628 660,815 66,181 594,634 Total derivatives subject to a master netting arrangement or similar arrangement 711,200 628 710,572 83,251 627,321 Total derivatives not subject to a master netting arrangement or similar arrangement (2) 5,444 — 5,444 2,079 3,365 Total Derivative Assets $ 716,644 $ 628 $ 716,016 $ 85,330 $ 630,686 December 31, 2018 Cash flow hedges $ 54,986 $ — $ 54,986 $ 22,451 $ 32,535 Other derivative activities (1) 460,822 6,570 454,252 117,582 336,670 Total derivatives subject to a master netting arrangement or similar arrangement 515,808 6,570 509,238 140,033 369,205 Total derivatives not subject to a master netting arrangement or similar arrangement (2) 2,677 — 2,677 — 2,677 Total Derivative Assets $ 518,485 $ 6,570 $ 511,915 $ 140,033 $ 371,882 (1) Includes customer-related and other derivatives.

INCOME TAXES

INCOME TAXES	9 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES An income tax provision of $112.9 million and $109.9 million was recorded for the three-month periods ended September 30, 2019 and 2018 , respectively. An income tax provision of $384.5 million and $374.2 million was recorded for the nine-month periods ended September 30, 2019 and 2018 , respectively. This resulted in an effective tax rate ("ETR") of 29.5% and 31.5% for the three-month periods ended September 30, 2019 and 2018 , respectively, and 29.6% and 30.3% for the nine-month periods ended September 30, 2019 and 2018 , respectively. The decrease in the ETR for the three-month and nine-month periods ended September 30, 2019 as compared to the three-month and nine-month periods ended September 30, 2018 was primarily due to certain recoveries related to amounts on account with the Internal Revenue Service (“IRS”). The Company is subject to the income tax laws of the U.S., its states and municipalities and certain foreign countries. These tax laws are complex and are potentially subject to different interpretations by the taxpayer and the relevant governmental taxing authorities. In establishing a provision for income tax expense, the Company must make judgments and interpretations about the application of these inherently complex tax laws. Actual income taxes paid may vary from estimates depending upon changes in income tax laws, actual results of operations, and the final audit of tax returns by taxing authorities. Tax assessments may arise several years after tax returns have been filed. The Company reviews its tax balances quarterly and, as new information becomes available, the balances are adjusted as appropriate. The Company is subject to ongoing tax examinations and assessments in various jurisdictions. NOTE 13. INCOME TAXES (continued) On September 5, 2019, the Federal District Court in Massachusetts entered a stipulated judgment resolving the Company’s litigation relating to the proper tax consequences of two financing transactions with an international bank through which the Company borrowed $1.2 billion that was previously disclosed within its Form 10-K for 2018. That stipulated judgment resolved the Company’s tax liability for the 2003 through 2005 tax years with no material effect on net income. The Company has agreed with the IRS to resolve the treatment of the same financing transactions for the 2006 and 2007 tax years, subject to review by the Congressional Joint Committee on Taxation and final IRS approval. That anticipated resolution with the IRS is consistent with the September 5, 2019, stipulated judgment and would have no material effect on net income. With few exceptions, the Company is no longer subject to federal, state and non-U.S. income tax examinations by tax authorities for years prior to 2006. The Company applies an aggregate portfolio approach whereby income tax effects from accumulated OCI are released only when an entire portfolio (i.e., all related units of account) of a particular type is liquidated, sold or extinguished. The Company had a net deferred tax liability balance of $990.8 million at September 30, 2019 (consisting of a deferred tax asset balance of $508.8 million and a deferred tax liability balance of $1.5 billion ), compared to a net deferred tax liability balance of $587.5 million at December 31, 2018 (consisting of a deferred tax asset balance of $625.1 million and a deferred tax liability balance of $1.2 billion ). The $403.3 million increase in net deferred liability for the nine-month period ended September 30, 2019 was primarily due to mark-to-mark adjustments and accelerated depreciation from leasing transactions.

FAIR VALUE

FAIR VALUE	9 Months Ended
	Sep. 30, 2019
Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE General A portion of the Company’s assets and liabilities are carried at fair value, including AFS investment securities and derivative instruments. In addition, the Company elects to account for its residential mortgages HFS and a portion of its MSRs at fair value. Fair value is also used on a nonrecurring basis to evaluate certain assets for impairment or for disclosure purposes. Examples of nonrecurring uses of fair value include impairments for certain loans and foreclosed assets. 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 in Level 1 that are observable for the assets or liabilities, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3 inputs are those that are unobservable or not readily observable for the asset or liability and are used to measure fair value to the extent relevant observable inputs are not available. Assets and liabilities measured at fair value, by their nature, result in a higher degree of financial statement volatility. When available, the Company uses quoted market prices or matrix pricing in active markets to determine fair value and classifies such items as Level 1 or Level 2 assets or liabilities. If quoted market prices in active markets are not available, fair value is determined using third-party broker quotes and/or discounted cash flow ("DCF") models incorporating various assumptions including interest rates, prepayment speeds and credit losses. Assets and liabilities valued using broker quotes and/or DCF models are classified as either Level 2 or Level 3, depending on the lowest level classification of an input that is considered significant to the overall valuation. NOTE 14. FAIR VALUE (continued) The Company values assets and liabilities based on the principal market in which each would be sold (in the case of assets) or transferred (in the case of liabilities). The principal market is the forum with the greatest volume and level of activity. In the absence of a principal market, the valuation is based on the most advantageous market. In the absence of observable market transactions, the Company considers liquidity valuation adjustments to reflect the uncertainty in pricing the instruments. The fair value of a financial asset is measured on a stand-alone basis and cannot be measured as a group, with the exception of certain financial instruments held and managed on a net portfolio basis. In measuring the fair value of a nonfinancial asset, the Company assumes the highest and best use of the asset by a market participant, not just the intended use, to maximize the value of the asset. The Company also considers whether any credit valuation adjustments are necessary based on the counterparty's credit quality. Any models used to determine fair values or validate dealer quotes based on the descriptions below are subject to review and testing as part of the Company's model validation and internal control testing processes. The Bank's Market Risk Department is responsible for determining and approving the fair values of all assets and liabilities valued at fair value, including the Company's Level 3 assets and liabilities. Price validation procedures are performed and the results are reviewed for Level 3 assets and liabilities by the Market Risk Department. Price validation procedures performed for these assets and liabilities can include comparing current prices to historical pricing trends by collateral type and vintage, comparing prices by product type to indicative pricing grids published by market makers, and obtaining corroborating dealer prices for significant securities. The Company reviews the assumptions utilized to determine fair value on a quarterly basis. Any changes in methodologies or significant inputs used in determining fair values are further reviewed to determine if a change in fair value level hierarchy has occurred. Transfers in and out of Levels 1, 2 and 3 are considered to be effective as of the end of the quarter in which they occur. There were no material transfers in or out of Level 1, 2, or 3 during the nine-month periods ended September 30, 2019 or 2018 for any assets or liabilities valued at fair value on a recurring basis. NOTE 14. FAIR VALUE (continued) Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present the assets and liabilities that are measured at fair value on a recurring basis by major product category and fair value hierarchy as of September 30, 2019 and December 31, 2018 .

(2) The Company had total MSRs of $128.5 million and $152.1 million as of September 30, 2019 .and December 31, 2018 , respectively. The Company has elected to account for the majority of its MSR balance using the FVO, while the remainder of the MSRs are accounted for using the lower of cost or fair value and are not presented within this table. (3) Refer to Note 3 for the fair value of investment securities and to Note 12 for the fair values of derivative assets and liabilities on a further disaggregated basis. (4) RICs collateralized by vehicle titles at SC and RV/marine loans at SBNA. (5) Residential mortgage loans. (6) Approximately $297.6 million of these financial assets were measured using model-based techniques, or Level 3 inputs, and represented approximately 2.0% of total assets measured at fair value on a recurring basis and approximately 0.2% of total consolidated assets. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The Company may be required to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with GAAP from time to time. These adjustments to fair value usually result from application of lower-of-cost-or-fair value accounting or certain impairment measures. Assets measured at fair value on a nonrecurring basis that were still held on the balance sheet were as follows: (in thousands) Level 1 Level 2 Level 3 Balance at Level 1 Level 2 Level 3 Balance at Impaired commercial LHFI $ — $ 162,177 $ 214,293 $ 376,470 $ 5,182 $ 150,208 $ 219,258 $ 374,648 Foreclosed assets — 15,045 62,293 77,338 — 16,678 81,208 97,886 Vehicle inventory — 318,435 — 318,435 — 342,617 — 342,617 LHFS (1) — 957,303 1,085,579 2,042,882 — — 1,073,795 1,073,795 Auto loans impaired due to bankruptcy — 197,729 — 197,729 — 189,114 — 189,114 MSRs — — 8,290 8,290 — — 9,386 9,386 (1) These amounts include $925.6 million and $1.1 billion of personal LHFS that were impaired as of September 30, 2019 and December 31, 2018 , respectively. NOTE 14. FAIR VALUE (continued) Valuation Processes and Techniques Impaired commercial LHFI in the table above represents the recorded investment of impaired commercial loans for which the Company measures impairment during the period based on the fair value of the underlying collateral supporting the loan. Written offers to purchase a specific impaired loan are considered observable market inputs, which are considered Level 1 inputs. Appraisals are obtained to support the fair value of the collateral and incorporate measures such as recent sales prices for comparable properties and are considered Level 2 inputs. Loans for which the value of the underlying collateral is determined using a combination of real estate appraisals, field examinations and internal calculations are classified as Level 3. The inputs in the internal calculations may include the loan balance, estimation of the collectability of the underlying receivables held by the customer used as collateral, sale and liquidation value of the inventory held by the customer used as collateral and historical loss-given-default parameters. In cases in which the carrying value exceeds the fair value of the collateral less cost to sell, an impairment charge is recognized. The net carrying value of these loans was $321.2 million and $479.4 million at September 30, 2019 and December 31, 2018 , respectively. Loans previously impaired which were not marked to fair value during the periods presented are excluded from this table. Foreclosed assets represent the recorded investment in assets taken during the period presented in foreclosure of defaulted loans, and are primarily comprised of commercial and residential real properties and generally measured at fair value less costs to sell. The fair value of the real property is generally determined using appraisals or other indications of market value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. 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 values of used cars. The Company's LHFS portfolios that are measured at fair value on a nonrecurring basis primarily consist of personal, commercial, and RICs LHFS. The estimated fair value of these LHFS is calculated based on a combination of estimated market rates for similar loans with similar credit risks and a DCF analysis in which the Company uses significant unobservable inputs on key assumptions, including historical default rates and adjustments to reflect voluntary prepayments, prepayment rates, discount rates reflective of the cost of funding, and credit loss expectations. The lower of cost or fair value adjustment for personal LHFS includes customer default activity and adjustments related to the net change in the portfolio balance during the reporting period. 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. Fair Value Adjustments The following table presents the increases and decreases in value of certain assets that are measured at fair value on a nonrecurring basis for which a fair value adjustment has been included in the Condensed Consolidated Statements of Operations relating to assets held at period-end: Three-Month Period Ended September 30, Nine-Month Period Ended September 30, (in thousands) Statement of Operations Location 2019 2018 2019 2018 Impaired LHFI Provision for credit losses $ (3,877 ) $ (45,515 ) $ (9,990 ) $ (44,936 ) Foreclosed assets Miscellaneous income, net (1) (4,014 ) (5,750 ) (7,798 ) (10,351 ) LHFS Provision for credit losses — — — (387 ) LHFS Miscellaneous income, net (1) (67,021 ) (86,838 ) (239,059 ) (236,549 ) Auto loans impaired due to bankruptcy Provision for credit losses 1,943 (5,034 ) (9,721 ) (93,846 ) MSRs Miscellaneous income, net (1) (128 ) (940 ) (483 ) (560 ) (1) Gains are disclosed as positive numbers while losses are shown as a negative number regardless of the line item being affected.

The gains in earnings reported in the table above related to the RICs HFI for which the Company elected the FVO are driven by three primary factors: 1) the recognition of interest income, 2) recoveries of previously charged-off RICs, and 3) actual performance of the portfolio since the Change in Control. Recoveries from RICs that were charged off at the Change in Control date are a direct increase to the gain recognized within the portfolio. In accordance with Accounting Standards Codification (“ASC") 805, Business Combinations , the Company did not ascribe a fair value to the portfolio of sub-prime charged-off RICs at the Change in Control date. Recoveries of previously charged off loans are usually recorded as a reduction to charge-offs in the period in which the recovery is made; however, in instances where the FVO is elected, it will flow through the fair value mark. At the Change in Control date, the UPB of the previously charged-off RIC portfolio was approximately $3.0 billion . Valuation Processes and Techniques - Recurring Fair Value Assets and Liabilities The following is a description of the valuation techniques used for instruments measured at fair value on a recurring basis: Debt Securities Classified as AFS Debt securities classified as AFS are accounted for at fair value. The Company utilizes a third-party pricing service to value its investment securities portfolios on a global basis. Its primary pricing service has consistently proved to be a high quality third-party pricing provider. For those investments not valued by pricing vendors, other trusted market sources are utilized. The Company monitors and validates the reliability of vendor pricing on an ongoing basis, which can include pricing methodology reviews, performing detailed reviews of the assumptions and inputs used by the vendor to price individual securities, and price validation testing. Price validation testing is performed independently of the risk-taking function and can include corroborating the prices received from third-party vendors with prices from another third-party source, reviewing valuations of comparable instruments, comparison to internal valuations, or by reference to recent sales of similar securities. NOTE 14. FAIR VALUE (continued) The classification of securities within the fair value hierarchy is based upon the activity level in the market for the security type and the observability of the inputs used to determine their fair values. Actively traded quoted market prices for debt securities AFS, such as U.S. Treasury and government agency securities, corporate debt, state and municipal securities, and MBS, are not readily available. The Company's principal markets for its investment securities are the secondary institutional markets with an exit price that is predominantly reflective of bid-level pricing in these markets. These investment securities are priced by third-party pricing vendors. The third-party vendors use a variety of methods when pricing these securities that incorporate relevant observable market data to arrive at an estimate of what a buyer in the marketplace would pay for a security under current market conditions. These investment securities are, therefore, considered Level 2. Certain ABS are valued using DCF models. The DCF models are obtained from a third-party pricing vendor who uses observable market data and therefore are classified as Level 2. Other ABS that could not be valued using a third-party pricing service are valued using an internally-developed DCF model. When estimating the fair value using this model, the Company uses its best estimate of the key assumptions, which include the discount rates and forward yield curves. The Company uses comparable bond indices based on industry, term, and rating to discount the expected future cash flows. Determining the comparability of assets involves significant subjectivity related to asset type differences, cash flows, performance and other inputs. The inability of the Company to corroborate the fair value of the ABS due to the limited available observable data on these ABS resulted in a fair value classification of Level 3. Realized gains and losses on investments in debt securities are recognized in the Consolidated Statements of Operations through Net gain/(loss) on sale of investment securities . RICs HFI For certain RICs HFI, the Company has elected the FVO. The fair values of RICs are estimated using the DCF model. In 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 voluntary prepayments, prepayment rates based on available data from a comparable market securitization of similar assets, discount rates reflective of the cost of funding debt issuances and recent historical equity yields, recovery rates based on the average severity utilizing reported severity rates and loss severity utilizing available market data from a comparable securitized pool. Accordingly, RICs HFI for which the Company has elected the FVO are classified as Level 3. LHFS The Company's LHFS portfolios that are measured at fair value on a recurring basis consist primarily of residential mortgage LHFS. The fair values of LHFS are estimated using published forward agency prices to agency buyers such as FNMA and FHLMC. The majority of the residential mortgage LHFS portfolio is sold to these two agencies. The fair value is determined using current secondary market prices for portfolios with similar characteristics, adjusted for servicing values and market conditions. These loans are regularly traded in active markets, and observable pricing information is available from market participants. The prices are adjusted as necessary to include the embedded servicing value in the loans as well as the specific characteristics of certain loans that are priced based on the pricing of similar loans. These adjustments represent unobservable inputs to the valuation, and are not significant given the relative insensitivity of the value to changes in these inputs to the fair value of the loans. Accordingly, residential mortgage LHFS are classified as Level 2. Gains and losses on residential mortgage LHFS are recognized in the Condensed Consolidated Statements of Operations through Miscellaneous income, net. See further discussion below in the section captioned "FVO for Financial Assets and Financial Liabilities." NOTE 14. FAIR VALUE (continued) MSRs The model to value MSRs estimates the present value of the future net cash flows from mortgage servicing activities based on various assumptions. These cash flows include servicing and ancillary revenue, offset by the estimated costs of performing servicing activities. Significant assumptions used in the valuation of residential MSRs include changes in anticipated loan prepayment rates ("CPRs") and the discount rate, reflective of a market participant's required return on an investment for similar assets. Other important valuation assumptions include market-based servicing costs and the anticipated earnings on escrow and similar balances held by the Company in the normal course of mortgage servicing activities. All of these assumptions are considered to be unobservable inputs. Historically, servicing costs and discount rates have been less volatile than CPR and earnings rates, both of which are directly correlated with changes in market interest rates. Increases in prepayment speeds, discount rates and servicing costs result in lower valuations of MSRs. Decreases in the anticipated earnings rate on escrow and similar balances result in lower valuations of MSRs. For each of these items, the Company makes assumptions based on current market information and future expectations. All of the assumptions are based on standards that the Company believes would be utilized by market participants in valuing MSRs and are derived and/or benchmarked against independent public sources. Accordingly, MSRs are classified as Level 3. Gains and losses on MSRs are recognized on the Condensed Consolidated Statements of Operations through Miscellaneous income, net. Listed below are the most significant inputs that are utilized by the Company in the evaluation of residential MSRs: • A 10% and 20% increase in the CPR speed would decrease the fair value of the residential servicing asset by $5.4 million and $10.7 million , respectively, at September 30, 2019 . • A 10% and 20% increase in the discount rate would decrease the fair value of the residential servicing asset by $4.1 million and $7.9 million , respectively, at September 30, 2019 . Significant increases/(decreases) in any of those inputs in isolation would result in significantly (lower)/higher fair value measurements, respectively. These sensitivity calculations are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of an adverse variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change. Prepayment estimates generally increase when market interest rates decline and decrease when market interest rates rise. Discount rates typically increase when market interest rates increase and/or credit and liquidity risks increase, and decrease when market interest rates decline and/or credit and liquidity conditions improve. Derivatives The valuation of these instruments is determined using commonly accepted valuation techniques, including DCF analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable and unobservable market-based inputs. The fair value represents the estimated amount the Company would receive or pay to terminate the contract or agreement, taking into account current interest rates, foreign exchange rates, equity prices and, when appropriate, the current creditworthiness of the counterparties. The Company incorporates credit valuation adjustments in the fair value measurement of its derivatives to reflect the counterparty's nonperformance risk in the fair value measurement of its derivatives, except for those derivative contracts with associated credit support annexes which provide credit enhancements, such as collateral postings and guarantees. The Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy. Certain of the Company's derivatives utilize Level 3 inputs, which are primarily related to mortgage banking derivatives-interest rate lock commitments and total return settlement derivative contracts. The DCF model is utilized to determine the fair value of the mortgage banking derivatives-interest rate lock commitments and the total return settlement derivative contracts. The significant unobservable inputs for mortgage banking derivatives used in the fair value measurement of the Company's loan commitments are "pull through" percentage and the MSR value that is inherent in the underlying loan value. The pull through percentage is an estimate of loan commitments that will result in closed loans. The significant unobservable inputs for total return settlement derivative contracts used in the fair value measurement of the Company's liabilities are discount percentages, which are based on comparable financial instruments. Significant increases (decreases) in any of these inputs in isolation would result in significantly higher (lower) fair value measurements. Significant increases (decreases) in the fair value of a mortgage banking derivative asset (liability) results when the probability of funding increases (decreases). Significant increases (decreases) in the fair value of a mortgage loan commitment result when the embedded servicing value increases (decreases). NOTE 14. FAIR VALUE (continued) Gains and losses related to derivatives affect various line items in the Condensed Consolidated Statements of Operations . See Note 12 for a discussion of derivatives activity.

NON-INTEREST INCOME AND OTHER EXPENSES (continued) Disaggregation of Revenue from Contracts with Customers Beginning January 1, 2018, the Company adopted the new accounting standard, "Revenue from Contracts with Customers", which requires the Company to disclose a disaggregation of revenue from contracts with customers that falls within the scope of this new accounting standard. The scope of this guidance explicitly excludes net interest income as well as many other revenues for financial assets and liabilities including loans, leases, securities, and derivatives. Therefore, the Company has evaluated the revenue streams within our Non-interest income line items to determine whether they are in-scope or out-of-scope. The following table presents the Company's Non-interest income disaggregated by revenue source: Three-Month Period Nine-Month Period Ended September 30, (in thousands) 2019 2018 2019 2018 Non-interest income: In-scope of revenue from contracts with customers: Depository services (1) $ 63,016 $ 59,704 $ 179,298 $ 175,482 Commission and trailer fees (2) 39,971 27,626 119,607 89,058 Interchange income, net (2) 16,891 15,780 49,854 45,423 Underwriting service fees (2) 27,043 11,282 77,835 60,626 Asset and wealth management fees (2) 35,169 41,190 109,166 121,544 Other revenue from contracts with customers (2) 9,924 8,807 30,303 26,493 Total in-scope of revenue from contracts with customers 192,014 164,389 566,063 518,626 Out-of-scope of revenue from contracts with customers: Consumer and commercial fees (3) 59,432 74,558 200,972 218,733 Lease income 735,783 610,324 2,116,503 1,720,526 Miscellaneous income/(loss) (3) 11,636 (25,527 ) (26,620 ) (13,518 ) Net gains/(losses) on sale of investment securities 2,267 (1,688 ) 2,646 (1,931 ) Total out-of-scope of revenue from contracts with customers 809,118 657,667 2,293,501 1,923,810 Total non-interest income $ 1,001,132 $ 822,056 $ 2,859,564 $ 2,442,436 (1) Primarily recorded in the Company's Condensed Consolidated Statements of Operations within Consumer and commercial fees . (2) Primarily recorded in the Company's Condensed Consolidated Statements of Operations within Miscellaneous income, net. (3) The balance presented excludes certain revenue streams that are considered in-scope and presented above. Arrangements with Multiple Performance Obligations Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling prices based on the prices charged to customers or using expected cost plus margin. Practical Expedients In instances where incremental costs, such as commission expenses, are incurred and the period of benefit is equal to or less than one year, the Company has elected to apply the practical expedient where the Company expenses such amounts as incurred. These costs are recorded within Compensation and benefits within the Condensed Consolidated Statements of Operations. In instances where contracts with customers contain a financing component and the Company expects the customer to pay for the goods or services within one year or less, the Company has elected to apply the practical expedient where the Company does not adjust the contracted amount of consideration for the effects of financing components. The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less or (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. As a result of the practical expedient and for the Company's material revenue streams, there are no unperformed performance obligations. As a result of the practical expedient and the Company's revenue recognition for contracts with customers, there are no material contract assets or liabilities. NOTE 15. NON-INTEREST INCOME AND OTHER EXPENSES (continued) Other Expenses The following table presents the Company's other expenses for the following periods: Three-Month Period Nine-Month Period Ended September 30, (in thousands) 2019 2018 2019 (1) 2018 Other expenses: Amortization of intangibles $ 14,742 $ 15,288 $ 44,250 $ 45,864 Deposit insurance premiums and other expenses 11,104 15,861 53,348 47,425 Loss on debt extinguishment 6 57 1,133 3,470 Other administrative expenses 145,870 119,385 404,399 359,132 Other miscellaneous expenses 18,407 8,813 33,236 11,761 Total Other expenses $ 190,129 $ 159,404 $ 536,366 $ 467,652 (1) The nine-month period ended September 30, 2019 includes $25.3 million of FDIC insurance premiums that relates to periods from the first quarter of 2015 through the fourth quarter of 2018. The Company has concluded that the out-of-period correction is immaterial to all impacted periods.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES AND GUARANTEES	COMMITMENTS, CONTINGENCIES AND GUARANTEES Off-Balance Sheet Risk - Financial Instruments In the normal course of business, the Company utilizes a variety of financial instruments with off-balance sheet risk to meet the financing needs of its customers and manage its exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, letters of credit, loans sold with recourse, forward contracts, and interest rate and cross currency swaps, caps and floors. These financial instruments may involve, to varying degrees, elements of credit, liquidity, and interest rate risk in excess of the amount recognized on the Condensed Consolidated Balance Sheet s. The contractual or notional amounts of these financial instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit, letters of credit and loans sold with recourse is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. For forward contracts and interest rate swaps, caps and floors, the contract or notional amounts do not represent exposure to credit loss. The Company controls the credit risk of its forward contracts and interest rate swaps, caps and floors through credit approvals, limits and monitoring procedures. See Note 12 to these Condensed Consolidated Financial Statements for discussion of all derivative contract commitments. The following table details the amount of commitments at the dates indicated: Other Commitments September 30, 2019 December 31, 2018 (in thousands) Commitments to extend credit $ 30,902,239 $ 30,269,311 Letters of credit 1,401,114 1,488,714 Commitments to sell loans 786,326 875 Unsecured revolving lines of credit 25,408 28,145 Recourse exposure on sold loans 52,973 49,733 Total commitments $ 33,168,060 $ 31,836,778 Commitments to Extend Credit Commitments to extend credit generally have fixed expiration dates, are variable rate, and contain provisions that permit the Company to terminate or otherwise renegotiate the contracts in the event of a significant deterioration in the customer’s credit quality. These arrangements normally require payment of a fee by the customer, the pricing of which is based on prevailing market conditions, credit quality, probability of funding, and other relevant factors. Since many of these commitments are expected to expire without being drawn upon, the contract amounts are not necessarily indicative of future cash requirements. NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Included within the reported balances for Commitments to extend credit at September 30, 2019 and December 31, 2018 are $5.8 billion and $5.7 billion , respectively, of commitments that can be canceled by the Company without notice. Commitments to extend credit also include amounts committed by the Company to fund its investments in CRA, LIHTC, and other equity method investments in which it is a limited partner. Letters of Credit The Company’s letters of credit meet the definition of a guarantee. Letters of credit commit the Company to make payments on behalf of its customers if specified future events occur. The guarantees are primarily issued to support public and private borrowing arrangements. The weighted average term of these commitments at September 30, 2019 was 10.2 months. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. In the event of a requested draw by the beneficiary that complies with the terms of the letter of credit, the Company would be required to honor the commitment. The Company has various forms of collateral for these letters of credit, including real estate assets and other customer business assets. The maximum undiscounted exposure related to these commitments at September 30, 2019 was $1.4 billion . The fees related to letters of credit are deferred and amortized over the life of the respective commitments, and were immaterial to the Company’s financial statements at September 30, 2019 . Management believes that the utilization rate of these letters of credit will continue to be substantially less than the amount of the commitments, as has been the Company’s experience to date. As of September 30, 2019 and December 31, 2018 , the liability related to these letters of credit was $6.2 million and $4.6 million , respectively, which is recorded within the reserve for unfunded lending commitments in Other liabilities on the Condensed Consolidated Balance Sheets . The credit risk associated with letters of credit is monitored using the same risk rating system utilized within the loan and financing lease portfolio. Also included within the reserve for unfunded lending commitments at September 30, 2019 and December 31, 2018 was the liability related to lines of credit outstanding of $86.7 million and $88.7 million , respectively. Unsecured Revolving Lines of Credit Such commitments arise primarily from agreements with customers for unused lines of credit on unsecured revolving accounts and credit cards, provided there is no violation of conditions in the underlying agreement. These commitments, substantially all of which the Company can terminate at any time and which do not necessarily represent future cash requirements, are reviewed periodically based on account usage, customer creditworthiness and loan qualifications. Loans Sold with Recourse The Company has loans sold with recourse that meet the definition of a guarantee. For loans sold with recourse under the terms of its multifamily sales program with the FNMA, the Company retained a portion of the associated credit risk. Commitments to Sell Loans The Company enters into forward contracts relating to its mortgage banking business to hedge the exposures from commitments to make new residential mortgage loans with existing customers and from mortgage loans classified as LHFS. These contracts mature in less than one year . Commitments to sell loans at September 30, 2019 include the commercial equipment finance leases and loans that will be sold to an unrelated third party as disclosed in Note 4. SC Commitments The following table summarizes liabilities recorded for commitments and contingencies as of September 30, 2019 and December 31, 2018 , all of which are included in Accounts payable and accrued expenses in the accompanying Condensed Consolidated Balance Sheet s: Agreement or Legal Matter Commitment or Contingency September 30, 2019 December 31, 2018 (in thousands) Chrysler Agreement Revenue-sharing and gain/(loss), net-sharing payments $ 22,560 $ 7,001 Agreement with Bank of America Servicer performance fee 4,068 6,353 Agreement with Citizens Bank of Philadelphia (CBP") Loss-sharing payments 1,866 3,708 Other contingencies Consumer arrangements 2,138 2,138 NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Following is a description of the agreements pursuant to which the liabilities in the preceding table were recorded. Chrysler Agreement On June 28, 2019, SC 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. Under terms of the Chrysler Agreement, SC 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 Chrysler Agreement also requires that SC maintain at least $5.0 billion in funding available for floor plan 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 SC. Agreement with Bank of America Until January 31, 2017, SC had a flow agreement with Bank of America whereby SC was committed to sell up to $300.0 million of eligible loans to the bank each month. SC 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 the time of sale. Servicer performance payments are due six years from the cut-off date of each loan sale. Agreement with CBP Until May 2017, SC sold loans to CBP under terms of a flow agreement and predecessor sale agreements. SC retains 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. Other Contingencies SC is or may be subject to potential liability under various other contingent exposures. SC had accrued $2.1 million at September 30, 2019 and December 31, 2018 , respectively, for other miscellaneous contingencies. Agreements Bluestem SC is party to agreements with Bluestem whereby SC is committed to purchase certain new advances on personal revolving financings receivables, along with existing balances on accounts with new advances, originated by Bluestem for an initial term ending in April 2020 and renewing through April 2022 at Bluestem's option. As of September 30, 2019 and December 31, 2018 , the total unused credit available to customers was $2.9 billion and $3.1 billion , respectively. In 2019, SC purchased $0.8 billion of receivables out of the $3.1 billion unused credit available to customers as of December 31, 2018. In 2018, SC purchased $1.2 billion of receivables out of the $3.9 billion unused credit available to customers as of December 31, 2017. In addition, SC purchased $137.8 million of receivables related to newly-opened customer accounts during the nine-month period ended September 30, 2019 . Each customer account generated under the agreements generally is approved with a credit limit higher than the amount of the initial purchase, with each subsequent purchase automatically approved as long as it does not cause the account to exceed its limit and the customer is in good standing. As of September 30, 2019 and December 31, 2018 , SC was obligated to purchase $10.1 million and $15.4 million , respectively, in receivables that had been originated by Bluestem but not yet purchased by SC. SC also is required to make a profit-sharing payment to Bluestem each month if performance exceeds a specified return threshold. The agreement, among other provisions, gives Bluestem the right to repurchase up to 9.99% of the existing portfolio at any time during the term of the agreement and, provides that if the repurchase right is exercised, Bluestem has the right to retain up to 20.00% of new accounts subsequently originated. NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Others Under terms of an application transfer agreement with Nissan, SC has the first opportunity to review for its own portfolio any credit applications turned down by Nissan’s captive finance company. The agreement does not require SC to originate any loans, but for each loan originated SC will pay Nissan a referral fee. In connection with the sale of RICs through securitizations and other sales, SC has made standard representations and warranties customary to the consumer finance industry. Violations of these representations and warranties may require SC to repurchase loans previously sold to on- or off-balance sheet Trusts or other third parties. As of September 30, 2019 , there were no loans that were the subject of a demand to repurchase or replace for breach of representations and warranties for SC's ABS or other sales. In the opinion of management, the potential exposure of other recourse obligations related to SC’s RICs sale agreements is not expected to have a material adverse effect on the Company's or SC’s business, consolidated financial position, results of operations, or cash flows. Santander has provided guarantees on the covenants, agreements, and obligations of SC under the governing documents of its warehouse facilities and privately issued amortizing notes. These guarantees are limited to the obligations of SC as servicer. In November 2015, SC executed a forward flow asset sale agreement with a third party under the terms of which SC is committed to sell $350.0 million in charged-off loan receivables in bankruptcy status on a quarterly basis. However, any sale of more than $275.0 million is subject to a market price check. The remaining aggregate commitment as of September 30, 2019 and December 31, 2018 not subject to a market price check was $39.8 million and $64.0 million , respectively. Other Off-Balance Sheet Risk Other off-balance sheet risk stems from financial instruments that do not meet the definition of guarantees under applicable accounting guidance, and from other relationships that include items such as indemnifications provided in the ordinary course of business and intercompany guarantees. Legal and Regulatory Proceedings Periodically, the Company is party to, or otherwise involved in, various lawsuits, investigations, regulatory matters 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, investigation, regulatory matter and/or legal proceeding, particularly where the claimants seek very large or indeterminate damages or where the matters present novel legal theories or involve a large number of parties, the Company generally cannot predict the eventual outcome of the pending matters, the timing of the ultimate resolution of the matters, or the eventual loss, fines or penalties related to the matters. Accordingly, except as provided below, the Company is unable to reasonably estimate a range of its potential exposure, if any, to these lawsuits, investigations, regulatory matters and other legal proceedings at this time. However, 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 have a material adverse effect on the Company's financial position, liquidity, and results of operations. In accordance with applicable accounting guidance, the Company establishes an accrued liability for litigation, investigations, 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, investigation or regulatory matter develops, the Company, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether the matter presents a material loss contingency that is probable and estimable. If a determination is made during a given quarter that a material loss contingency is probable and estimable, an accrued liability is established during such quarter with respect to such loss contingency, and the Company continues to monitor the matter for further developments that could affect the amount of the accrued liability previously established. As of September 30, 2019 and December 31, 2018 , the Company accrued aggregate legal and regulatory liabilities of $297.1 million and $215.2 million , respectively. Further, the Company estimates the aggregate range of reasonably possible losses for legal and regulatory proceedings in excess of reserves of up to approximately $185 million as of September 30, 2019 . Set forth below are descriptions of the material lawsuits, regulatory matters and other legal proceedings to which the Company is subject. NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) SHUSA Matters On March 21, 2017, SC and SHUSA entered into a written agreement with the FRB of Boston. Under the terms of that agreement, SC is required to enhance its compliance risk management program, board oversight of risk management and senior management oversight of risk management, and SHUSA is required to enhance its oversight of SC's management and operations. JPMorgan Chase Mortgage Loan Sale Indemnity Demand In connection with a 2007 sale by Sovereign Bank of approximately 35,000 second lien mortgage loans to JPMorgan Chase & Co. and certain of its subsidiaries, including EMC Mortgage LLC (collectively, “Chase”), Chase has asserted an indemnity claim against SBNA of approximately $40.0 million under the mortgage loan purchase agreement based on alleged breaches of representations and warranties. The parties are in discussions concerning this matter. SC Matters Securities Class Action and Shareholder Derivative Lawsuits Deka Lawsuit: SC 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 2014, was brought against SC, certain of its current and former directors and executive officers and certain institutions that served as underwriters in SC's initial public offering (the "IPO"), including SIS, on behalf of a class consisting of those who purchased or otherwise acquired SC securities between January 23, 2014 and June 12, 2014. The complaint alleges, among other things, that the IPO registration statement and prospectus and certain subsequent public disclosures violated federal securities laws by containing misleading statements concerning SC’s ability to pay dividends and the adequacy of SC’s compliance systems and oversight. In December 2015, SC 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 SC’s Board of Directors, and names SC 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 SC’s nonprime auto lending practices, resulting in harm to SC. 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 SC’s Board of Directors, and names SC as a nominal defendant. The complaint alleges, among other things, that the defendants breached their fiduciary duties in connection with SC’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. NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Consumer Lending Cases SC 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 “ECOA”), the Fair Debt Collection Practices Act, the 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. In general, these cases seek damages and equitable and/or other relief. Regulatory Investigations and Proceedings SC is party to, or is periodically otherwise involved in, reviews, investigations, examinations and proceedings (both formal and informal), and information-gathering requests, by government and self-regulatory agencies, including the FRB of Boston, the CFPB, the Department of Justice (the “DOJ”), the SEC, the Federal Trade Commission and various state regulatory and enforcement agencies. Currently, such matters include, but are not limited to, the following: • SC received a civil subpoena from the DOJ under Financial Institutions Reform, Recovery and Enforcement Act requesting the production of documents and communications that, among other things, relate to the underwriting and securitization of nonprime vehicle loans. SC has responded to these requests within the deadlines specified in the subpoenas and has otherwise cooperated with the DOJ with respect to this matter. • In October 2014, May 2015, July 2015 and February 2017, SC received subpoenas and/or civil investigative demands ("CIDs") from the Attorneys General of California, Illinois, Oregon, New Jersey, Maryland and Washington under the authority of each state's consumer protection statutes. SC has been informed that these states will serve as an executive committee on behalf of a group of 33 state Attorneys General (and the District of Columbia). The subpoenas and/or CIDs from the executive committee states contain broad requests for information and the production of documents related to SC’s underwriting, securitization, servicing and collection of nonprime vehicle loans. SC has responded to these requests within the deadlines specified in the CIDs, and has otherwise cooperated with the Attorneys General with respect to this matter. • In August 2017 and July 2019, SC received CIDs from the CFPB. The stated purpose of the CIDs are to determine whether SC has complied with the Fair Credit Reporting Act and related regulations. SC has responded to these requests within the applicable deadlines and has otherwise cooperated with the CFPB with respect to this matter. Mississippi Attorney General Lawsuit In January 2017, the Attorney General of the State of Mississippi (the "Mississippi AG") filed a lawsuit against SC in the Chancery Court of the First Judicial District of Hinds County, State of Mississippi, captioned State of Mississippi ex rel. Jim Hood, Attorney General of the State of Mississippi v. Santander Consumer USA Inc., C.A. # G-2017-28. The complaint alleges that SC engaged in unfair and deceptive business practices to induce Mississippi consumers to apply for loans that they could not afford. The complaint asserts claims under the Mississippi Consumer Protection Act and seeks unspecified civil penalties, equitable relief and other relief. In March 2017, SC filed motions to dismiss the lawsuit and the parties are proceeding with discovery. Servicemembers’ Civil Relief Act (“SCRA ” ) Consent Order In February 2015, SC entered into a consent order with the DOJ, approved by the United States District Court for the Northern District of Texas, which resolves the DOJ's claims against SC that certain of its repossession and collection activities during the period between January 2008 and February 2013 violated the SCRA. The consent order requires SC to pay a civil fine in the amount of $55,000 , as well as at least $9.4 million to affected service members consisting of $10,000 per service member plus compensation for any lost equity (with interest) for each repossession by SC, and $5,000 per service member for each instance where SC sought to collect repossession-related fees on accounts where a repossession was conducted by a prior account holder. The consent order also provides for monitoring by the DOJ of SC’s SCRA compliance for a period of five years and requires SC to undertake certain additional remedial measures. IHC Matters Periodically, SSLLC is party to pending and threatened legal actions and proceedings, including Financial Industry Regulatory Authority (“FINRA”) arbitration actions and class action claims. NOTE 16. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Puerto Rico FINRA Arbitration As of September 30, 2019 , SSLLC had received 741 FINRA arbitration cases related to Puerto Rico bonds and Puerto Rico closed-end funds ("CEFs"), generally, that SSLLC previously recommended and/or sold to clients. Most of these cases are based upon concerns regarding the local Puerto Rico securities market. The statements of claims allege, among other things, fraud, negligence, breach of fiduciary duty, breach of contract, unsuitability, over-concentration and failure to supervise. There were 469 arbitration cases pending as of September 30, 2019 . The Company believes it's reasonably possible it could experience an increase in claims in future periods. Puerto Rico Putative Class Action: SSLLC, Santander BanCorp, BSPR, the Company and Santander are defendants in a putative class action alleging federal securities and common law claims relating to the solicitation and purchase of more than $180.0 million of Puerto Rico bonds and $101.0 million of CEFs during the period from December 2012 to October 2013. The case is pending in the United States District Court for the District of Puerto Rico and is captioned Jorge Ponsa-Rabell, et. al. v. SSLLC, Civ. No. 3:17-cv-02243. The amended complaint alleges that defendants acted in concert to defraud purchasers in connection with the underwriting and sale of Puerto Rico municipal bonds, CEFs and open-end funds. In May 2019, the defendants filed a motion to dismiss the amended complaint. Puerto Rico Municipal Bond Insurer Litigation: On August 8, 2019, bond insurers National Public Finance Guarantee Corporation and MBIA Insurance Corporation filed suit in Puerto Rico state court against eight Puerto Rico municipal bond underwriters, including SSLLC, alleging that the underwriters made misrepresentations in connection with the issuance of the debt and that the bond insurers relied on such misrepresentations in agreeing to insure certain of the bonds. The complaint alleges damages of not less than $720.0 million . The defendants removed the case to federal court, and plaintiffs have sought to return the case to state court. Mexican Government Bonds Consolidated Purported Antitrust Class Action : A consolidated purported antitrust class action is pending in the United States District Court, Southern District of New York, captioned In re Mexican Government Bonds Antitrust Litigation, No. 1:18-cv-02830-JPO (the “MGB Lawsuit”). The MGB Lawsuit is against the Company, SIS, Santander, Banco Santander (Mexico), S.A. Institucion de Banca Multiple, Grupo Financiero Santander and Santander Investment Bolsa, Sociedad de Valores, S.A. on behalf of a class of persons who entered into Mexican government bond (“MGB”) transactions between January 1, 2006 and April 19, 2017, where such persons were either domiciled in the United States or, if domiciled outside the United States, transacted in the United States. The complaint alleges, among other things, that the Santander defendants and the other defendants violated U.S. antitrust laws by conspiring to rig auctions and/or fix prices of MGBs. On September 30, 2019, the court granted the defendants motions to dismiss the consolidated complaint. These matters are ongoing and could in the future result in the imposition of damages, fines or other penalties. No assurance can be given that the ultimate outcome of these matters or any resulting proceedings would not materially and adversely affect the Company's business, financial condition and results of operations.

The Company and its affiliates also entered into or were subject to various service agreements with Santander and its affiliates. Each of these agreements was made in the ordinary course of business and on market terms. Contributions from Santander that impact common stock and paid-in capital within the Condensed Consolidated Statements of Stockholder's Equity are disclosed within the table below: Nine-Month Period Ended September 30, (in thousands) 2019 2018 Cash contribution $ 88,927 $ 5,741 Adjustment to book value of assets purchased on January 1 — 277 Deferred tax asset on purchased assets — 3,156 Contribution from shareholder $ 88,927 $ 9,174 NOTE 17.

The Company re-evaluated the assets received on January 1, 2018 and recorded an additional $0.3 million to additional paid-in capital. The Company contributed these assets at book value of $3.1 million to SBNA, a subsidiary of the Company, on January 1, 2018. During the first quarter of 2018, the Company recorded a $3.2 million deferred tax asset on the assets purchased by the Company to establish the intangible under Section 197 of the Internal Revenue Code. During the nine-month period ended September 30, 2019 , the Company received $88.9 million of capital contributions from Santander. On March 29, 2017, SC entered into a Master Securities Purchase Agreement ("MSPA") with Santander, under which it has the option to sell a contractually determined amount of eligible prime loans to Santander through the Santander Private Auto Issuing Note trust securitization platform, for a term that ended in December 2018. SC provided servicing on all loans originated under this arrangement. For the three-month and nine-month periods ended September 30, 2018 , SC sold $0.3 billion and $2.9 billion of loans, respectively, at fair value under this MSPA. Total losses of $4.2 million and $24.3 million were recognized for the three-month and nine-month periods ended September 30, 2018 , respectively. Servicing fee income of $4.7 million and $20.9 million was recognized in the Condensed Consolidated Statements of Operations for the three-month and nine-month periods ended September 30, 2019 , respectively, and $10.0 million and $25.8 million for the three-month and nine-month periods ended September 30, 2018 , respectively. SC had $17.9 million and $16.0 million of collections due to Santander as of September 30, 2019 and December 31, 2018 , respectively. Beginning in 2018, SC agreed to provide SBNA with origination support services in connection with the processing, underwriting, and purchase of RICs, primarily from Chrysler dealers. In addition, SC agreed to perform the servicing for any RICs originated on SBNA's behalf. During the three-month and nine-month period ended September 30, 2019 , SC facilitated the purchase of $2.1 billion and $5 billion , respectively, of RICs. During the three-month and nine-month periods ended September 30, 2018 , SC facilitated the purchase of $685 million and $738 million , respectively, of RICs. SC recognizes referral fee income and servicing fee income related to this agreement that eliminates in the consolidation of SHUSA.

Segment Reporting [Abstract]
BUSINESS SEGMENT INFORMATION	BUSINESS SEGMENT INFORMATION Business Segment Products and Services The Company’s reportable segments are focused principally around the customers the Company serves. During the fourth quarter of 2018, the Chief Operating Decision Maker (the “CODM”) drove a reorganization of the Company's business leadership to better align the teams with how the CODM allocates resources and assesses business performance. Changes were made to the internal management reporting in 2019 and, accordingly, beginning in the first quarter of 2019, the prior Commercial Banking segment is now reported as two separate reportable segments: C&I and CRE & Vehicle Finance (“VF”). All prior period results have been recast to conform to the new composition of reportable segments. The Company has identified the following reportable segments: • The Consumer and Business Banking segment includes the products and services provided to Bank consumer and business banking customers, including consumer deposit, business banking, residential mortgage, unsecured lending and investment services. This segment offers a wide range of products and services to consumers and business banking customers, including demand and interest-bearing demand deposit accounts, money market and savings accounts, CDs and retirement savings products. It also offers lending products such as credit cards, mortgages, home equity lines of credit, and business loans such as business lines of credit and commercial cards. In addition, the Bank provides investment services to its retail customers, including annuities, mutual funds, and insurance products. Santander Universities, which provides grants and scholarships to universities and colleges as a way to foster education through research, innovation and entrepreneurship, is the last component of this segment. • The C&I segment currently provides commercial lines, loans, letters of credit, receivables financing and deposits to medium- and large-sized commercial customers, as well as financing and deposits for government entities. This segment also provides niche product financing for specific industries. NOTE 18. BUSINESS SEGMENT INFORMATION (continued) • The CRE & VF segment offers CRE loans and multifamily loans to customers. This segment also offers commercial loans to dealers and financing for commercial equipment and vehicles. • The CIB segment serves the needs of global commercial and institutional customers by leveraging the international footprint of Santander to provide financing and banking services to corporations with over $500 million in annual revenues. CIB also includes SIS, a registered broker-dealer located in New York that provides services in investment banking, institutional sales, and trading and offering research reports of Latin American and European equity and fixed-income securities. CIB's offerings and strategy are based on Santander's local and global capabilities in wholesale banking. • SC is a specialized consumer finance company focused on vehicle finance and third-party servicing. SC’s primary business is the indirect origination of RICs, principally through manufacturer-franchised dealers in connection with their sale of new and used vehicles to retail consumers. In conjunction with the Chrysler Agreement, SC offers a full spectrum of auto financing products and services to FCA customers and dealers under the Chrysler Capital brand. These products and services include consumer RICs and leases, as well as dealer loans for inventory, construction, real estate, working capital and revolving lines of credit. SC also originates vehicle loans through a web-based direct lending program, purchases vehicle RICs from other lenders, and services automobile, recreational and marine vehicle portfolios for other lenders. During 2015, SC announced its intention to exit the personal lending business. SC has entered into a number of intercompany agreements with the Bank as described above as part of the Other segment. All intercompany revenue and fees between the Bank and SC are eliminated in the consolidated results of the Company. The Other category includes certain immaterial subsidiaries such as BSI, BSPR, SSLLC, and SFS, the unallocated interest expense on the Company's borrowings and other debt obligations and certain unallocated corporate income and indirect expenses. This category also includes the Bank’s community development finance activities, including originating CRA-eligible loans and making CRA-eligible investments. The Company’s segment results, excluding SC and the entities that have been transferred to the IHC, are derived from the Company’s business unit profitability reporting system by specifically attributing managed balance sheet assets, deposits and other liabilities and their related interest income or expense to each of the segments. Funds transfer pricing ("FTP") methodologies are utilized to allocate a cost for funds used or a credit for funds provided to business line deposits, loans and selected other assets using a matched funding concept. The methodology includes a liquidity premium adjustment, which considers an appropriate market participant spread for commercial loans and deposits by analyzing the mix of borrowings available to the Company with comparable maturity periods. Other income and expenses are managed directly by each reportable segment, including fees, service charges, salaries and benefits, and other direct expenses, as well as certain allocated corporate expenses, and are accounted for within each segment’s financial results. Accounting policies for the lines of business are the same as those used in preparation of the Condensed Consolidated Financial Statements with respect to activities specifically attributable to each business line. However, the preparation of business line results requires management to establish methodologies to allocate funding costs and benefits, expenses and other financial elements to each line of business. Where practical, the results are adjusted to present consistent methodologies for the segments. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. The implementation of these enhancements to the internal management reporting methodology may materially affect the results disclosed for each segment with no impact on consolidated results. Whenever significant changes to management reporting methodologies take place, prior period information is reclassified wherever practicable. The CODM manages SC on a historical basis by reviewing the results of SC on a pre-Change in Control basis. The Results of Segments table discloses SC's operating information on the same basis that it is reviewed by the CODM. The adjustments column includes adjustments to reconcile SC's GAAP results to SHUSA's consolidated results. NOTE 18.

BASIS OF PRESENTATION AND ACC_2

BASIS OF PRESENTATION AND ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These Condensed Consolidated Financial Statements include accounts of the Company and its consolidated subsidiaries, and certain special purpose financing trusts that are considered VIEs. The Company generally consolidates VIEs for which it is deemed to be the primary beneficiary and voting interest entities ("VOEs") in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. These Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and pursuant to SEC regulations for interim financial information. Additionally, where applicable, the Company's accounting policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. In the opinion of management, the accompanying Condensed Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary for a fair statement of the Condensed Consolidated Balance Sheets , Statements of Operations , Statements of Comprehensive Income , Statements of Stockholder's Equity and Statements of Cash Flows ("SCF") for the periods indicated, and contain adequate disclosure of this interim financial information to make the information presented not misleading. These Condensed Consolidated Financial Statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2018 .
Recently Adopted Accounting Standards and Recent Accounting Developments	Recently Adopted Accounting Standards Since January 1, 2019, the Company adopted the following Financial Accounting Standards Board ("FASB") Accounting Standards Updates (“ASUs"): • ASU 2016-02, Leases (Topic 842) . The Company adopted this standard as of January 1, 2019, resulting in the recognition of a right of-use (“ROU”) asset ( $664.1 million ) and lease liability ( $705.7 million ) in the Consolidated Balance Sheet for all operating leases with a term greater than 12 months. The Company adopted this ASU using the modified retrospective approach, with application at the adoption date and a cumulative-effect adjustment to the opening balance of retained earnings. Under this approach, comparative periods were not adjusted. We elected the package of practical expedients permitted under transition guidance, which allowed us to carry forward the historical lease classification. We also elected not to recognize a lease liability and associated ROU asset for short-term leases. We did not elect (1) the hindsight practical expedient when determining the lease term and (2) the practical expedient to not separate non-lease components from lease components. The ASU required the Company to accelerate the recognition of $18.7 million of previously deferred gains on sale-leaseback transactions, with such impact recorded to the opening balance of Retained earnings. The ROU asset and lease liability will subsequently be de-recognized in a manner that effectively yields a straight-line lease expense over the lease term. Lessee accounting requirements for finance leases (previously described as capital leases) and lessor accounting requirements for operating, sales-type, and direct financing leases (sales-type and direct financing leases were both previously referred to as capital leases) are largely unchanged. This standard did not materially affect our Consolidated Statements of Operations or SCF. • 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 capitalized costs will be presented with Other assets on the balance sheet, and the amortization expense will be presented in the Technology, outside service, and marketing expense line of the Statement of Operations. The Company has early adopted this standard effective January 1, 2019 and it did not have a material impact on the Company's Condensed Consolidated Financial Statements or related disclosures. The adoption of the following ASUs did not have a material impact on the Company's 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. 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 are not measured at fair value through net income. 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 remaining 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. For AFS debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the OTTI framework. The standard also simplifies the accounting framework for purchased credit-impaired debt securities and loans. The Company will adopt the new guidance on January 1, 2020. The Company established a cross-functional working group for implementation of this standard. Our implementation process includes 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 frameworks, updating accounting policies and procedures, and determining future expanded disclosures on aspects such as credit quality. The status of our implementation is periodically presented to the Audit Committee and the Risk Committee. The Company continues to test and refine its CECL models to satisfy the requirements of the new standard. Oversight and testing, as well as efforts to meet expanded disclosure requirements, will extend through the remainder of 2019. The Company currently expects an increase in the allowance for credit losses ("ACL") for loans in the range of 55% to 70% and a decrease (net of tax) in our regulatory capital amounts and ratios. The Company expects to leverage relief provided by federal banking regulatory agencies for an initial capital decrease by phasing in the adoption over four years on a straight-line basis in its calculation of regulatory capital amounts and ratios. The Company does not expect a material impact on its other financial instruments. The increase in the ACL will be reflected as a decrease to opening retained earnings, net of income taxes, at January 1, 2020. The estimated increase will take into account 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. This estimate is subject to further refinement based on continuing reviews and approvals of models, methodologies and judgments. The impact at January 1, 2020 will depend upon the nature and characteristics of our financial instruments at the adoption date, the macroeconomic conditions and forecasts at that date, and other management judgments. 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 . This 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 timin g of transfers between levels, and the valuation processes for Level 3 fair value measurements. This ASU requires disclosure of changes in unrealized gains and losses for the period included in OCI (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. This new guidance will be effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the effect the new guidance will have on its Consolidated Financial Statements and related disclosures. In addition to those described in detail above, the Company is in the process of evaluating ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities , but does not expect it to have a material impact on the Company's financial position, results of operations, or disclosures.
Commercial Lending Asset Quality Indicators	Commercial Lending Asset Quality Indicators The Company's Risk Department performs a credit analysis and classifies certain loans over an internal threshold based on the commercial lending classifications described below: 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 acquire and 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. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) 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 uncollectible 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.
TDRs	Commercial Loan TDRs All of the Company’s commercial loan modifications are based on the circumstances of the individual customer, including specific customers' complete relationships with the Company. Loan terms are modified to meet each borrower’s particular circumstances at a point in time and may allow for modifications such as term extensions and interest rate reductions. Modifications for commercial loan TDRs generally, although not always, result in bifurcation of the original loan into A and B notes. The A note is restructured to allow for upgraded risk rating and return to accrual status after a sustained period of payment performance has been achieved (typically six months for monthly payment schedules). The B note, if any, is structured as a deficiency note; the balance is charged off but the debt is usually not forgiven. Commercial TDRs are generally placed on non-accrual status until the Company believes repayment under the revised terms is reasonably assured and a sustained period of repayment performance has been achieved (typically six months for a monthly amortizing loan). TDRs are subject to analysis for specific reserves by either calculating the present value of expected future cash flows or, if collateral-dependent, calculating the fair value of the collateral less its estimated cost to sell. The TDR classification will remain on the loan until it is paid in full or liquidated. Consumer Loan TDRs The primary modification program for the Company’s residential mortgage and home equity portfolios is a proprietary program designed to keep customers in their homes and, when appropriate, prevent them from entering into foreclosure. The program is available to all customers facing a financial hardship regardless of their delinquency status. The main goal of the modification program is to review the customer’s entire financial condition to ensure that the proposed modified payment solution is affordable according to a specific DTI ratio range. The main modification benefits of the program allow for term extensions, interest rate reductions, and/or deferment of principal. The Company reviews each customer on a case-by-case basis to determine which benefit or combination of benefits will be offered to achieve the target DTI range. For the Company’s other consumer portfolios, including RICs and auto loans, the terms of the modifications generally include one or a combination of: a reduction of the stated interest rate of the loan to a rate of interest lower than the current market rate for new debt with similar risk or an extension of the maturity date. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Consumer TDRs excluding RICs are generally placed on non-accrual status until the Company believes repayment under the revised terms is reasonably assured and a sustained period of repayment performance has been achieved (typically six months for a monthly amortizing loan). Any loan that has remained current for the six months immediately prior to modification will remain on accrual status after the modification is implemented. RIC TDRs are placed on nonaccrual status when the Company believes repayment under the revised terms is not reasonably assured, and considered for return to accrual when a sustained period of repayment performance has been achieved. The TDR classification will remain on the loan until it is paid in full or liquidated. In addition to loans identified as TDRs above, the guidance also requires loans discharged under Chapter 7 bankruptcy proceedings to be considered TDRs and collateral-dependent, regardless of delinquency status. TDRs that are collateral-dependent loans must be written down to the fair market value of the collateral, less costs to sell and classified as non-accrual/NPLs for the remaining life of the loan. TDR Impact to ALLL The ALLL is established to recognize losses inherent in funded loans intended to be HFI that are probable and can be reasonably estimated. Prior to loans being placed in TDR status, the Company generally measures its allowance under a loss contingency methodology in which consumer loans with similar risk characteristics are pooled and loss experience information is monitored for credit risk and deterioration with statistical tools considering factors such as delinquency, LTV and credit scores. Upon TDR modification, the Company generally measures impairment based on a present value of expected future cash flows methodology considering all available evidence, by discounting expected future cash flows using the original effective interest rate or fair value of collateral less costs to sell. The amount of the required ALLL is equal to the difference between the loan’s impaired value and the recorded investment. RIC TDRs that subsequently default continue to have impairment measured based on the difference between the recorded investment of the RIC and the present value of expected cash flows. For the Company's other consumer TDR portfolios, impairment on subsequent defaults is generally measured based on the fair value of the collateral, if applicable, less its estimated cost to sell. Typically, commercial loans whose terms are modified in a TDR will have been identified as impaired prior to modification and accounted for generally using a present value of expected future cash flows methodology, unless the loan is considered collateral-dependent. Loans considered collateral-dependent are measured for impairment based on their fair values of collateral less estimated cost to sell. Accordingly, upon TDR modification or if a TDR modification subsequently defaults, the allowance methodology remains unchanged.
General	General A portion of the Company’s assets and liabilities are carried at fair value, including AFS investment securities and derivative instruments. In addition, the Company elects to account for its residential mortgages HFS and a portion of its MSRs at fair value. Fair value is also used on a nonrecurring basis to evaluate certain assets for impairment or for disclosure purposes. Examples of nonrecurring uses of fair value include impairments for certain loans and foreclosed assets. 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 in Level 1 that are observable for the assets or liabilities, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3 inputs are those that are unobservable or not readily observable for the asset or liability and are used to measure fair value to the extent relevant observable inputs are not available. Assets and liabilities measured at fair value, by their nature, result in a higher degree of financial statement volatility. When available, the Company uses quoted market prices or matrix pricing in active markets to determine fair value and classifies such items as Level 1 or Level 2 assets or liabilities. If quoted market prices in active markets are not available, fair value is determined using third-party broker quotes and/or discounted cash flow ("DCF") models incorporating various assumptions including interest rates, prepayment speeds and credit losses. Assets and liabilities valued using broker quotes and/or DCF models are classified as either Level 2 or Level 3, depending on the lowest level classification of an input that is considered significant to the overall valuation. NOTE 14. FAIR VALUE (continued) The Company values assets and liabilities based on the principal market in which each would be sold (in the case of assets) or transferred (in the case of liabilities). The principal market is the forum with the greatest volume and level of activity. In the absence of a principal market, the valuation is based on the most advantageous market. In the absence of observable market transactions, the Company considers liquidity valuation adjustments to reflect the uncertainty in pricing the instruments. The fair value of a financial asset is measured on a stand-alone basis and cannot be measured as a group, with the exception of certain financial instruments held and managed on a net portfolio basis. In measuring the fair value of a nonfinancial asset, the Company assumes the highest and best use of the asset by a market participant, not just the intended use, to maximize the value of the asset. The Company also considers whether any credit valuation adjustments are necessary based on the counterparty's credit quality. Any models used to determine fair values or validate dealer quotes based on the descriptions below are subject to review and testing as part of the Company's model validation and internal control testing processes. The Bank's Market Risk Department is responsible for determining and approving the fair values of all assets and liabilities valued at fair value, including the Company's Level 3 assets and liabilities. Price validation procedures are performed and the results are reviewed for Level 3 assets and liabilities by the Market Risk Department. Price validation procedures performed for these assets and liabilities can include comparing current prices to historical pricing trends by collateral type and vintage, comparing prices by product type to indicative pricing grids published by market makers, and obtaining corroborating dealer prices for significant securities. The Company reviews the assumptions utilized to determine fair value on a quarterly basis. Any changes in methodologies or significant inputs used in determining fair values are further reviewed to determine if a change in fair value level hierarchy has occurred. Transfers in and out of Levels 1, 2 and 3 are considered to be effective as of the end of the quarter in which they occur.
