Accounting Policies [Abstract]
BASIS OF PRESENTATION AND ACCOUNTING POLICIES	BASIS OF PRESENTATION AND ACCOUNTING POLICIES Introduction SHUSA is the Parent Company of SBNA, a national banking association; SC, a consumer finance company; Santander BanCorp, a financial holding company headquartered in Puerto Rico that offers a full range of financial services through its wholly-owned banking subsidiary, BSPR; SSLLC, a broker-dealer headquartered in Boston, Massachusetts; BSI, a financial services company headquartered in Miami, Florida that offers a full range of banking services to foreign individuals and corporations based primarily in Latin America; and SIS, a registered broker-dealer headquartered 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, SAM, are registered investment advisers with the SEC. SHUSA is headquartered in Boston and the Bank's home office is in Wilmington, Delaware. SHUSA is a wholly-owned subsidiary of 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. SC's primary business is the indirect origination and servicing of 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. SAF is SC’s primary vehicle brand, and is available as a finance option for automotive dealers across the United States. Since May 2013, under its agreement with FCA, SC has operated as FCA's preferred provider for consumer loans, leases, and dealer loans and provides 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 20 for additional details. On June 28, 2019, SC entered into an amendment to its agreement with FCA, which modified that agreement to, among other things, adjust certain performance metrics, exclusivity commitments and payment provisions. 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. However, in 2015, SC announced its exit from personal lending and, accordingly, all of its personal lending assets are classified as HFS at December 31, 2019. As of December 31, 2019 , SC was owned approximately 72.4% by SHUSA and 27.6% by other shareholders. SC Common Stock is listed on the NYSE under the trading symbol "SC." During 2019, SBNA completed the sale of 14 bank branches and four 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 . NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) IHC The EPS mandated by Section 165 of the DFA Final Rule were enacted by the Board of Governors of the Federal Reserve to strengthen regulatory oversight of 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. SFS’s results of operations, financial condition, and cash flows are immaterial to the historical financial results of the Company and the Company also elected to report its results prospectively. As a result of the 2017 contribution of SFS in 2017 and SAM in 2018, SHUSA's net income is understated by $1.0 million and $6.0 million for the years ended December 31, 2018 and 2017, respectively. In addition, a contribution to stockholder's equity of $4.4 million and $322.1 million was recorded on July 2, 2018, and July 1, 2017, respectively. These amounts are immaterial to the overall presentation of the Company's financial statements for each of the periods presented. On October 21, 2019, the Company entered into an agreement to sell the stock of Santander BanCorp (the holding company that owns BSPR) for a total consideration of approximately $1.1 billion , subject to adjustment based on the consolidated Santander BanCorp balance sheet at closing. At December 31, 2019, BSPR had 27 branches, approximately 1,000 employees, and total assets of approximately $6.0 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 a third party 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. Once it becomes apparent that this transaction is more likely than not to receive regulatory approval, the Company will recognize a deferred tax liability of approximately $50 million for the unremitted earnings of Santander BanCorp. Consummation of the transaction is not expected to result in any material gain or loss. Basis of Presentation These 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 VOEs in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. These Consolidated Financial Statements have been prepared in accordance with GAAP and pursuant to SEC regulations. 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 Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary for a fair statement of the Consolidated Balance Sheets , Statements of Operations , Statements of Comprehensive Income , Statements of Stockholder's Equity and SCF for the periods indicated, and contain adequate disclosure of this interim financial information to make the information presented not misleading. Certain prior-year amounts have been reclassified to conform to the current year presentation. These reclassifications did not have a material impact on the Company's consolidated financial condition or results of operations. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates, and those differences may be material. The most significant estimates pertain to fair value measurements, the ALLL and reserve for unfunded lending commitments, accretion of discounts and subvention on RICs, estimates of expected residual values of leased vehicles subject to operating leases, goodwill, and income taxes. Actual results may differ from the estimates, and the differences may be material to the Consolidated Financial Statements. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Recently Adopted Accounting Standards Since January 1, 2019, the Company adopted the following FASB ASUs: • ASU 2016-02, Leases (Topic 842) . The Company adopted this standard as of January 1, 2019, resulting in the recognition of a 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. 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 2018-15, 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. • 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. Significant Accounting Policies Consolidation In accordance with the applicable accounting guidance for consolidations, the Consolidated Financial Statements include any VOEs in which the Company has a controlling financial interest and any VIEs for which the Company is deemed to be the primary beneficiary. The Company consolidates its VIEs if the Company has (i) a variable interest in the entity; (ii) the power to direct activities of the VIE that most significantly impact the entity's economic performance; and (iii) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE (i.e., the Company is considered to be the primary beneficiary). The Company generally consolidates its VOEs if the Company, directly or indirectly, owns more than 50% of the outstanding voting shares of the entity and the noncontrolling shareholders do not hold any substantive participating or controlling rights. Interests in VIEs and VOEs can include equity interests in corporations, partnerships and similar legal entities, subordinated debt, securitizations, derivatives contracts, leases, service agreements, guarantees, standby letters of credit, loan commitments, and other contracts, agreements and financial instruments. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Upon the occurrence of certain significant events, as required by the VIE model, the Company reassesses whether a legal entity in which the Company is involved is a VIE. The reassessment process considers whether the Company has acquired or divested the power to direct the activities of the VIE through changes in governing documents or other circumstances. The reassessment also considers whether the Company has acquired or disposed of a financial interest that could be significant to the VIE, or whether an interest in the VIE has become significant or is no longer significant. The consolidation status of the entities with which the Company is involved may change as a result of such reassessments. Changes in consolidation status are applied prospectively, with assets and liabilities of a newly consolidated VIE initially recorded at fair value. A gain or loss may be recognized upon deconsolidation of a VIE, depending on the carrying amounts of deconsolidated assets and liabilities compared to the fair value of retained interests and ongoing contractual arrangements. The Company uses the equity method to account for unconsolidated investments in VOEs if the Company has significant influence over the entity's operating and financing decisions but does not maintain a controlling financial interest. Unconsolidated investments in VOEs or VIEs in which the Company has a voting or economic interest of less than 20% generally are carried at cost less any impairment. These investments are included in Other assets on the Consolidated Balance Sheets, and the Company's proportionate share of income or loss is included in Miscellaneous income, net within the Consolidated Statements of Operations. Sales of RICs and Leases The Company, through SC, transfers RICs into newly formed Trusts which then issue one or more classes of notes payable backed by the RICs. The Company’s continuing involvement with the credit facilities and Trusts are in the form of servicing loans held by the SPEs and, generally, through holding a residual interest in the SPE. These transactions are structured without recourse. The Trusts are considered VIEs under GAAP and are consolidated when the Company has: (a) power over the significant activities of the entity and (b) an obligation to absorb losses or the right to receive benefits from the VIE which are potentially significant to the VIE. The Company has power over the significant activities of those Trusts as servicer of the financial assets held in the Trust. Servicing fees are not considered significant variable interests in the Trusts; however, when the Company also retains a residual interest in the Trust, either in the form of a debt security or equity interest, the Company has an obligation to absorb losses or the right to receive benefits that are potentially significant to the SPE. Accordingly, these Trusts are consolidated within the Consolidated Financial Statements, and the associated RICs, borrowings under credit facilities and securitization notes payable remain on the Consolidated Balance Sheets. Securitizations involving Trusts in which the Company does not retain a residual interest or any other debt or equity interest are treated as sales of the associated RICs. While these Trusts are included in our Consolidated Financial Statements, they are separate legal entities; thus, the finance receivables and other assets sold to these Trusts are legally owned by the Trusts, are available only to satisfy the notes payable related to the securitized RICs, and are not available to the Company's creditors or other subsidiaries. The Company also sells RICs and leases to VIEs or directly to third parties. The Company may determine that these transactions meet sale accounting treatment in accordance with applicable guidance. Due to the nature, purpose, and activity of these transactions, the Company either does not hold potentially significant variable interests or is not the primary beneficiary as a result of the Company's limited further involvement with the financial assets. The transferred financial assets are removed from the Company's Consolidated Balance Sheets at the time the sale is completed. The Company generally remains the servicer of the financial assets and receives servicing fees. The Company also recognizes a gain or loss for the difference between the fair value, as measured based on sales proceeds plus (or minus) the value of any servicing asset (or liability) retained and the carrying value of the assets sold. See further discussion on the Company's securitizations in Note 7 to these Consolidated Financial Statements. Cash, Cash Equivalents, and Restricted Cash Cash and cash equivalents include cash and amounts due from depository institutions, interest-bearing deposits in other banks, federal funds sold, and securities purchased under agreements to resell. Cash and cash equivalents have original maturities of three months or less and, accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value. The Company has maintained balances in various operating and money market accounts in excess of federally insured limits. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Cash deposited to support securitization transactions, lockbox collections, and the related required reserve accounts is recorded in the Company's Consolidated Balance Sheets as restricted cash. Excess cash flows generated by Trusts are added to the restricted cash reserve account, creating additional over-collateralization until the contractual securitization requirement has been reached. Once the targeted reserve requirement is satisfied, additional excess cash flows generated by the Trusts are released to the Company as distributions from the Trusts. Lockbox collections are added to restricted cash and released when transferred to the appropriate warehouse facility or Trust. The Company also maintains restricted cash primarily related to cash posted as collateral related to derivative agreements and cash restricted for investment purposes. Investment Securities and Other Investments Investment in debt securities are classified as either AFS, HTM, trading, or other investments. Investments in equity securities are generally recorded at fair value with changes recorded in earnings. Management determines the appropriate classification at the time of purchase. Debt securities expected to be held for an indefinite period of time are classified as AFS and are carried at fair value, with temporary unrealized gains and losses reported as a component of accumulated other comprehensive income within stockholder's equity, net of estimated income taxes. Debt securities purchased which the Company has the positive intent and ability to hold until maturity are classified as HTM securities. HTM securities are reported at cost and adjusted for payments, amortization of premium and accretion of discount. Transfers of debt securities into the HTM category from the AFS category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in OCI and in the carrying value of the HTM securities. Such amounts are amortized over the remaining lives of the securities. The Company conducts a comprehensive security-level impairment assessment quarterly on all securities with a fair value that is less than their amortized cost basis to determine whether the loss represents OTTI. The quarterly OTTI assessment takes into consideration whether (i) the Company has the intent to sell or, (ii) it is more likely than not that it will be required to sell the security before the expected recovery of its amortized cost. The Company also considers whether or not it would expect to receive all of the contractual cash flows from the investment based on its assessment of the security structure, recent security collateral performance metrics, external credit ratings, failure of the issuer to make scheduled interest or principal payments, judgment and expectations of future performance, and relevant independent industry research, analysis and forecasts. The Company also considers the severity of the impairment in its assessment. In the event of a credit loss, the credit component of the impairment is recognized within non-interest income as a separate line item, and the non-credit component is recorded within accumulated OCI. Realized gains and losses on sales of investment securities are recognized on the trade date and included in earnings within Net (losses)/gains on sale of investment securities, which is a component of non-interest income. Unamortized premiums and discounts are recognized in interest income over the estimated life of the security using the interest method. Debt securities held for trading purposes and equity securities are carried at fair value, with changes in fair value recorded in non-interest income. Investments that are purchased principally for the purpose of economically hedging the MSR in the near term are classified as trading securities and carried at fair value, with changes in fair value recorded as a component of the Miscellaneous income, net line of the Consolidated Statements of Operations. Other investments primarily include the Company's investment in the stock of the FHLB of Pittsburgh and the FRB. Although FHLB and FRB stock are equity interests in the FHLB and FRB, respectively, neither has a readily determinable fair value, because ownership is restricted and they are not readily marketable. FHLB stock can be sold back only at its par value of $100 per share and only to FHLBs or to another member institution. Accordingly, FHLB stock and FRB stock are carried at cost. The Company evaluates this investment for impairment on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. See Note 3 to the Consolidated Financial Statements for details on the Company's investments. LHFI LHFI include commercial and consumer loans (including RICs) originated by the Company as well as loans acquired by the Company, which the Company intends to hold for the foreseeable future or until maturity. RICs consist largely of nonprime automobile finance receivables that are acquired individually from dealers at a nonrefundable discount from the contractual principal amount. RICs also include receivables originated through a direct lending program and loan portfolios purchased from other lenders. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Originated LHFI Originated LHFI are reported net of cumulative charge offs, unamortized loan origination fees and costs, and unamortized discounts and premiums. Interest on loans is credited to income as it is earned. For most of the Company's originated LHFI, loan origination fees and certain direct loan origination costs and premiums and discounts are deferred and recognized as adjustments to interest income in the Consolidated Statements of Operations over the contractual life of the loan utilizing the effective interest method. For RICs, loan origination fees and costs, premiums and discounts are deferred and amortized over their estimated lives as adjustments to interest income utilizing the effective interest method using estimated prepayment speeds, which are updated on a monthly basis. The Company estimates future principal prepayments specific to pools of homogeneous loans, which are based on the vintage, credit quality at origination and term of the loan. Prepayments in our portfolio are sensitive to credit quality, with higher credit quality loans experiencing higher voluntary prepayment rates than lower credit quality loans. The resulting prepayment rate specific to each pool is based on historical experience and is used as an input in the calculation of the constant effective yield. The impact of defaults is not considered in the prepayment rate; the prepayment rate only considers voluntary prepayments. Our estimated weighted average prepayment rates ranged from 5.1% to 11.0% at December 31, 2019 and 5.7% to 10.8% at December 31, 2018 . The Company’s LHFI are carried at amortized cost, net of the ALLL. When a RIC is originated, certain cost basis adjustments (the net discounts) to the principal balance of the loan are recognized in accordance with the accounting guidance for loan origination fees and costs in ASC 310-20. These cost basis adjustments generally include the following: • Origination costs. • Dealer discounts - dealer discounts to the principal balance of the loan generally occur in circumstances in which the contractual interest rate on the loan is not sufficient to compensate for the credit risk of the borrower. • Participation - participation fees, or premiums, paid to the dealer as a form of profit-sharing, rewarding the dealer for originating loans that perform. • Subvention - payments received from the vehicle manufacturer as compensation (yield enhancement) for the cost of below-market interest rates offered to consumers. Originated loans are initially recorded at the proceeds paid to fund the loan. Loan origination fees and costs and any discount at origination for loans is considered by the Company to reflect yield enhancements and is accreted to income using the effective interest method. See LHFS subsection below for accounting treatment when an HFI loan is re-designated as LHFS. Purchased LHFI Purchased loans are generally loans acquired in a bulk purchase or business combination. RICs acquired directly from a dealer are considered to be originated loans, not purchased loans. Purchase discounts and premiums on purchased loans that are deemed performing are accreted over the remaining expected lives of the loans to their par values, generally using the retrospective effective interest method, which considers the impact of estimated prepayments that is updated on a quarterly basis. The purchase discount on personal unsecured loans (given their revolving nature) are amortized on a straight-line basis in accordance with ASC 310-20. Purchased loans with evidence of credit quality deterioration as of the purchase date for which it is probable that the Company will not receive all contractually required payments receivable are accounted for as PCI loans. At acquisition, PCI loans are recorded at fair value with no allowance for credit losses, and accounted for individually or aggregated in pools based on similar risk characteristics. The Company estimates the amount and timing of expected cash flows for each loan or pool of loans. The expected cash flows in excess of the amount paid for the loans is referred to as the accretable yield and is recorded as interest income over the remaining estimated life of the loan or pool of loans. The Company may irrevocably elect to account for certain loans acquired with evidence of credit deterioration at fair value in accordance with ASC 825. Accordingly, the Company does not recognize interest income for these loans and recognizes the fair value adjustments on these loans as part of other non-interest income in the Company’s Consolidated Statements of Operations. For certain loans which the Company has elected to account for at fair value that are not considered non-accrual, the Company separately recognizes interest income from the total fair value adjustment. No ALLL is recognized for loans that the Company has elected to account for at fair value. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) ALLL for Loan Losses and Reserve for Unfunded Lending Commitments The ALLL and reserve for unfunded lending commitments (together, the ACL) are maintained at levels that management considers adequate to provide for losses on the recorded investment of the loan portfolio, based upon an evaluation of known and inherent risks in the loan portfolio. Management's evaluation takes into consideration the risks in the loan portfolio, past loan and lease loss experience, specific loans with loss potential, geographic and industry concentrations, delinquency trends, economic conditions and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the ACL may be necessary if conditions differ substantially from the assumptions used in making the evaluations. The ALLL consists of two elements: (i) an allocated allowance, which is comprised of allowances established on loans specifically evaluated for impairment, and loans collectively evaluated for impairment, based on historical loan and lease loss experience adjusted for current trends and both general economic conditions and other risk factors in the Company's loan portfolios, and (ii) an unallocated allowance to account for a level of imprecision in management's estimation process. Reserve levels are collectively reviewed for adequacy and approved quarterly by Board-level committees. The ALLL includes the estimate of credit losses that management expects will be realized during the loss emergence period, including the amount of net discounts that is included in the loans' recorded investment at the time of charge-off. In the case of loans purchased in a bulk purchase or business combination, the entire discount on the loan portfolio is considered as available to absorb the credit losses when determining the ALLL. For these loans, the Company records provisions for credit losses when incurred losses exceed the unaccreted purchase discount. Provisions for credit losses are charged to provision expense in amounts sufficient to maintain the ACL at levels considered adequate to cover probable credit losses incurred in the Company’s HFI loan portfolios. The Company uses the incurred loss approach in providing an ACL on the recorded investment of its existing loans. This approach requires that loan loss provisions are recognized and the corresponding allowance recorded when, based on all available information, it is probable that a credit loss has been incurred. The estimate for credit losses for loans that are individually evaluated for impairment is generally determined through an analysis of the present value of the loan’s expected future cash flows, except for those that are deemed to be collateral dependent. For those loans that are collectively assessed for impairment, the Company utilizes historical loan loss experience information as part of its evaluation. In addition, when establishing the collective ACL for originated loans, the Company’s estimate of losses on recorded investment includes the estimate of the related net discount balance that is expected at the time of charge-off. Although the ACL is established on a collective basis, actual charge-offs are recorded on a loan-by-loan basis when losses are confir

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 measured at amortized cost. The amendment introduces a new credit reserving framework known as CECL, which replaces the incurred loss impairment framework in current GAAP with one that reflects expected credit losses over the full expected life of financial assets and commitments, and requires consideration of a broader range of reasonable and supportable information, including estimation of future expected changes in macroeconomic conditions. Additionally, the standard changes the accounting framework for purchased credit-deteriorated HTM debt securities and loans, and dictates measurement of AFS debt securities using an allowance instead of reducing the carrying amount as it is under the current OTTI framework. The Company adopted the new guidance on January 1, 2020. The Company established a cross-functional working group for implementation of this standard. Generally, our implementation process included data sourcing and validation, development and validation of loss forecasting methodologies and models, including determining the length of the reasonable and supportable forecast period and selecting macroeconomic forecasting methodologies to comply with the new guidance, updating the design of our established governance, financial reporting, and internal control over financial reporting frameworks, and updating accounting policies and procedures. The status of our implementation was periodically presented to the Audit Committee and the Risk Committee. The Company completed multiple parallel model runs to test and refine its current expected credit loss models to satisfy the requirements of the new standard. The adoption of this standard resulted in the increase in the ACL of approximately $2.5 billion and a decrease to opening retained earnings, net of income taxes, at January 1, 2020. The estimated increase is based on forecasts of expected future economic conditions and is primarily driven by the fact that the allowance will cover expected credit losses over the full expected life of the loan portfolios. The standard did not have a material impact on the Company’s other financial instruments. Additionally, we elected to utilize regulatory relief which will permit us to phase in 25 percent of the capital impact of CECL in our calculation of regulatory capital amounts and ratios in 2020, and an additional 25 percent each subsequent year until fully phased-in by the first quarter of 2023. 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. The Company adopted the new guidance effective January 1, 2020 and it did not have a material impact on the Company’s business, financial position or results of operations. In addition to those described in detail above, on January 1, 2020, the Company adopted ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities , and it did not have a material impact on the Company's business, financial position, results of operations, or disclosures.

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 FICO scores and weighted average 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. The Company did no t record any OTTI related to its investments in debt securities for the years ended December 31, 2019 , 2018 or 2017. Management has concluded that the unrealized losses on its investments in debt securities for which it has not recognized OTTI (which were comprised of 727 individual securities at December 31, 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 Investments in Debt Securities Proceeds from sales of investments in debt securities and the realized gross gains and losses from those sales were as follows: Year Ended December 31, (in thousands) 2019 2018 2017 Proceeds from the sales of AFS securities $ 1,423,579 $ 1,262,409 $ 3,256,378 Gross realized gains $ 9,496 $ 5,517 $ 22,224 Gross realized losses (3,680 ) (12,234 ) (24,668 ) OTTI — — — Net realized gains/(losses) (1) $ 5,816 $ (6,717 ) $ (2,444 ) (1) Includes net realized gain/(losses) on trading securities of (0.8) million , $(1.4) million and $(4.2) million for the years ended December 31, 2019 , 2018 and 2017, respectively. The Company uses the specific identification method to determine the cost of the securities sold and the gain or loss recognized. NOTE 3. INVESTMENT SECURITIES (continued) Other Investments Other Investments consisted of the following as of: (in thousands) December 31, 2019 December 31, 2018 FHLB of Pittsburgh and FRB stock $ 716,615 $ 631,239 LIHTC investments 265,271 163,113 Equity securities not held for trading 12,697 10,995 Trading securities 1,097 10 Total $ 995,680 $ 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 year ended December 31, 2019 , the Company purchased $298.6 million of FHLB stock at par, and redeemed $212.4 million of FHLB stock at par. There was no gain or loss associated with these redemptions. During the year ended December 31, 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 December 31, 2019 , with changes in fair value recognized in net income, and consist primarily of 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.

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 SPEs. These loans totaled $53.9 billion at December 31, 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 December 31, 2019 was $1.4 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 $ 289.0 million as of December 31, 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 16 to these 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 Consolidated Statements of Operations . As of December 31, 2019 , the carrying value of the personal unsecured HFS portfolio was $1.0 billion . During 2019, the Company sold $1.4 billion of performing residential loans to FNMA for a net gain of $7.9 million . In October 2019, SBNA agreed to sell from its portfolio certain restructured residential mortgage and home equity loans (with approximately $187.0 million of principal balances outstanding) to two unrelated third parties. This transaction settled in the fourth quarter with an immaterial impact on the Consolidated Statements of Operations. The loans were sold with servicing released to the purchasers. On October 4, 2019, SBNA agreed to sell approximately $768.2 million of equipment finance loans and approximately $74.2 million of operating leases to an unrelated third party. This transaction settled on November 29, 2019, with a gain of $5.6 million on the sale. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) 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 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 December 31, 2019 and December 31, 2018 , accrued interest receivable on the Company's loans was $497.7 million and $524.0 million , respectively. During the years ended December 31, 2019 , 2018 and 2017 , the Company purchased retail installment contract financial receivables from third-party lenders for $1.1 billion , $67.2 thousand and zero , respectively. The UPB of these loans as of the acquisition date was $1.12 billion , $74.1 thousand and zero , respectively.

These items resulted in a net increase in the loan balances of $3.2 billion and $1.4 billion as of December 31, 2019 and December 31, 2018 , respectively. (2) Other commercial includes CEVF leveraged leases and loans. (3) Other consumer primarily includes 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. 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. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) 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. At December 31, 2019 and 2018 , the Company had $279.4 million and $803.1 million , respectively, of loans originated prior to the Change in Control. The purchase marks on these portfolios were $726.5 thousand and $2.1 million at December 31, 2019 and 2018 , respectively. During the years ended December 31, 2019 and 2018 , SC originated $12.8 billion and $7.9 billion , respectively, in Chrysler Capital loans (including the SBNA originations program), which represented 56% and 46% , respectively, of the UPB of SC's total RIC originations (including the SBNA originations program).

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. 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. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) 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.

(2) FICO score at origination. 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.

VIEs

VIEs	12 Months Ended
	Dec. 31, 2019
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 Consolidated Balance Sheets . The collateral borrowings under credit facilities and securitization notes payable of the Company’s consolidated VIEs remain on the 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 Consolidated Balance Sheets . The Company also uses a titling trust to originate and hold its leased vehicles and the associated leases in order to facilitate the pledging of leases to financing facilities or the sale of leases to other parties without incurring the costs and administrative burden of retitling the leased vehicles. This titling trust is considered a VIE. NOTE 7. VIEs (continued) On-balance sheet VIEs The assets of consolidated VIEs that are included in the Company's 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) December 31, 2019 December 31, 2018 Assets Restricted cash $ 1,629,870 $ 1,582,158 Loans 26,532,328 24,098,638 Operating lease assets, net 16,461,982 13,978,855 Various other assets 625,359 685,383 Total Assets $ 45,249,539 $ 40,345,034 Liabilities Notes payable $ 34,249,851 $ 31,949,839 Various other liabilities 188,093 122,010 Total Liabilities $ 34,437,944 $ 32,071,849 (1) Certain amounts shown above are greater than the amounts shown in the corresponding line items in the accompanying Consolidated Balance Sheets due to intercompany eliminations between the VIEs and other entities consolidated by the Company. For example, for most of its securitizations, the Company retains one or more of the lowest tranches of bonds. Rather than showing investment in bonds as an asset and the associated debt as a liability, these amounts are eliminated in consolidation as required by GAAP. The Company retains servicing rights for receivables transferred to the Trusts and receives a monthly servicing fee on the outstanding principal balance. Supplemental fees, such as late charges, for servicing the receivables are reflected in Miscellaneous income, net. As of December 31, 2019 and December 31, 2018 , the Company was servicing $27.3 billion and $27.1 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 Trusts for the years ended December 31, 2019 , 2018 and 2017 is as follows: Year Ended December 31, (in thousands) 2019 2018 2017 Assets securitized $ 22,286,033 $ 26,650,284 $ 18,442,793 Net proceeds from new securitizations (1) $ 17,199,821 $ 17,338,880 $ 14,126,211 Net proceeds from sale of retained bonds 251,602 1,059,694 499,354 Cash received for servicing fees (2) 990,612 887,988 866,210 Net distributions from Trusts (2) 3,615,461 2,767,509 2,613,032 Total cash received from Trusts $ 22,057,496 $ 22,054,071 $ 18,104,807 (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 year ended December 31, 2019 , the Company sold no RICs to VIEs in off-balance sheet securitizations. During the years ended December 31, 2018 , and 2017 the Company sold $2.9 billion and $2.6 billion , respectively, of gross RICs to VIEs in off- balance sheet securitizations for a loss of $20.7 million and $13.0 million , respectively. Beginning in 2017, the transactions were executed under the Company's securitization platforms with Santander. Santander holds eligible vertical interests in notes and certificates of not less than 5% to comply with the DFA's risk retention rules. NOTE 7. VIEs (continued) As of December 31, 2019 and December 31, 2018 , the Company was servicing $2.4 billion and $4.1 billion , respectively, of gross RICs that have been sold in off-balance sheet securitizations and were subject to an optional clean-up call.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLES	GOODWILL AND OTHER INTANGIBLES Goodwill Goodwill is assigned to reporting units, which are operating segments or one level below an operating segment, as of the acquisition date. The following table presents the Company's goodwill by its reporting units at December 31, 2019 : (in thousands) Consumer and Business Banking C&I (1) CRE and Vehicle Finance CIB SC Total Goodwill at December 31, 2018 $ 1,880,304 $ 1,412,995 $ — $ 131,130 $ 1,019,960 $ 4,444,389 Re-allocations during the period — (1,095,071 ) 1,095,071 — — — Goodwill at December 31, 2019 $ 1,880,304 $ 317,924 $ 1,095,071 $ 131,130 $ 1,019,960 $ 4,444,389 (1) Formerly Commercial Banking. 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 that there was no impairment. See Note 23 to these Consolidated Financial Statements for additional details on the change in reportable segments. During 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. This change in reportable segments was impacted by the 2019 change in reportable segments discussed above. There were no disposals, additions or impairments of goodwill for the years ended December 31, 2019 or 2018 . There were no disposals, additions or re-allocations of goodwill for 2017 . After conducting an analysis of the fair value of each reporting unit as of October 1, 2017, the Company determined that the full amount of goodwill attributed to Santander BanCorp of $10.5 million was impaired and, as a result, it was written off, primarily due to the unfavorable economic environment in Puerto Rico and the additional adverse effects of Hurricane Maria. 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, 2019 using generally accepted valuation methods. NOTE 8.

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 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 16 to these Consolidated Financial Statements 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 ISDA Master Agreements if the Company's ratings fall below a specified level, typically investment grade. As of December 31, 2019 , derivatives in this category had a fair value of $1.0 million . The credit ratings of the Company and the Bank are currently considered investment grade. During the fourth quarter of 2019 , no additional collateral would be required if there were a further 1 - or 2 - notch downgrade by either S&P or Moody's. As of December 31, 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 $7.8 million and $9.5 million , respectively. The Company had $8.6 million and $11.5 million in cash and securities collateral posted to cover those positions as of December 31, 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 December 31, 2019 , the Company expected $6.7 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.

DERIVATIVES (continued) Derivatives Designated in Hedge Relationships – Notional and Fair Values Derivatives designated as accounting hedges at December 31, 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) December 31, 2019 Cash flow hedges: Pay fixed — receive variable interest rate swaps $ 2,650,000 $ 2,807 $ 39,128 1.85 % 1.91 % 1.86 Pay variable - receive fixed interest rate swaps 7,570,000 7,462 29,209 1.43 % 1.73 % 2.39 Interest rate floor 3,800,000 18,762 — 0.19 % — % 1.28 Total $ 14,020,000 $ 29,031 $ 68,337 1.17 % 1.29 % 1.99 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 14. 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.

The net amount of change recognized in OCI for cash flow hedge derivatives were losses of $0.5 million and $7.1 million , net of tax, for the years ended December 31, 2019 and December 31, 2018 , respectively, and a gain of $18.1 million , net of tax, for the year ended December 31, 2017 . The net amount of changes reclassified from OCI into earnings for cash flow hedge derivatives were losses of $0.2 million and $3.3 million , net of tax, for the years ended December 31, 2019 and December 31, 2018 , respectively, and a gain of $17.8 million , net of tax, for the year ended December 31, 2017 . 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 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 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 Consolidated Balance Sheets " section of the tables below. NOTE 14. DERIVATIVES (continued) Information about financial assets and liabilities that are eligible for offset on the Consolidated Balance Sheets as of December 31, 2019 and December 31, 2018 , respectively, is presented in the following tables: Offsetting of Financial Assets Gross Amounts Not Offset in the Consolidated Balance Sheets (in thousands) Gross Amounts of Recognized Assets Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts of Assets Presented in the Consolidated Balance Sheets Collateral Received (3) Net Amount December 31, 2019 Cash flow hedges $ 29,031 $ — $ 29,031 $ 17,790 $ 11,241 Other derivative activities (1)(4) 524,258 435 523,823 51,437 472,386 Total derivatives subject to a master netting arrangement or similar arrangement 553,289 435 552,854 69,227 483,627 Total derivatives not subject to a master netting arrangement or similar arrangement (2) 3,042 — 3,042 — 3,042 Total Derivative Assets $ 556,331 $ 435 $ 555,896 $ 69,227 $ 486,669 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	12 Months Ended
	Dec. 31, 2019
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES 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 15. INCOME TAXES (continued) Income Taxes from Continuing Operations The provision for income taxes in the Consolidated Statements of Operations is comprised of the following components: Year Ended December 31, (in thousands) 2019 2018 2017 Current: Foreign $ 491 $ 13,183 $ 7,288 Federal 40,964 (68,160 ) 24,335 State 91,592 64,002 7,951 Total current 133,047 9,025 39,574 Deferred: Foreign 38,471 16,882 (15,065 ) Federal 263,970 360,780 (193,837 ) State 36,711 39,213 12,288 Total deferred 339,152 416,875 (196,614 ) Total income tax provision/(benefit) $ 472,199 $ 425,900 $ (157,040 ) Reconciliation of Statutory and Effective Tax Rate The following is a reconciliation of the U.S. federal statutory rate of 21.0% for the years ended December 31, 2019 and 2018 and 35% for the year ended December 31, 2017 to the Company's effective tax rate for each of the years indicated: Year Ended December 31, 2019 2018 2017 Federal income tax at statutory rate 21.0 % 21.0 % 35.0 % Increase/(decrease) in taxes resulting from: Valuation allowance 2.4 % 4.6 % 0.9 % Tax-exempt income (0.9 )% (0.8 )% (1.9 )% Section 162(m) limitation 0.2 % 0.2 % — % Non-deductible FDIC insurance premiums 0.8 % 0.8 % — % BOLI (0.9 )% (0.9 )% (2.8 )% State income taxes, net of federal tax benefit 6.1 % 5.9 % 2.6 % General business tax credits (1.6 )% (1.7 )% (2.1 )% Electric vehicle credits (0.4 )% (0.7 )% (3.0 )% Basis in SC 3.4 % 3.0 % 3.4 % Uncertain tax position reserve (0.1 )% (0.3 )% (0.4 )% Tax reform — % — % (53.3 )% Other 1.2 % (1.0 )% 2.0 % Effective tax rate 31.2 % 30.1 % (19.6 )% NOTE 15.

The IRC Section 475 mark-to-market adjustment deferred tax asset is related to SC's business as a dealer, which is required to be recognized under IRC Section 475 for net gains that have been recognized for tax purposes on loans that are required to be marked to market for tax purposes but not book purposes. The leasing transactions deferred tax liability is primarily related to accelerated tax depreciation on leasing transactions. The SC basis difference deferred tax liability is the book over tax basis difference in the Company's investment in SC. The deferred tax liability would be realized upon the Company's disposition of its interest in SC or through dividends received from SC. If the Company were to reach 80% or more ownership of SC, SC would be consolidated with the Company for tax filing purposes, facilitating certain offsets of SC’s taxable income, and the capital planning benefit of netting SC’s net deferred tax liability against the Company’s net deferred tax asset. In addition, the SC basis difference DTL would be released as a reduction to income tax expense. NOTE 15. INCOME TAXES (continued) Periodic reviews of the carrying amount of deferred tax assets are made to determine if the establishment of a valuation allowance is necessary. If, based on the available evidence in future periods, it is more likely than not that all or a portion of the Company’s deferred tax assets will not be realized, a deferred tax valuation allowance would be established. Consideration is given to all positive and negative evidence related to the realization of the deferred tax assets. Items considered in this evaluation include historical financial performance, the expectation of future earnings, the ability to carry back losses to recoup taxes previously paid, the length of statutory carryforward periods, experience with operating loss and tax credit carryforwards not expiring unused, tax planning strategies and timing of reversals of temporary differences. The Company's evaluation is based on current tax laws, as well as its expectations of future performance. As of December 31, 2019 , the Company maintained a valuation allowance of $371.5 million , compared to $338.9 million as of December 31, 2018 , related to deferred tax assets subject to carryforward periods for which the Company has determined it is more likely than not that these deferred tax assets will remain unused after the carryforward periods have expired. The $32.6 million increase year-over-year was primarily driven by increased losses of subsidiaries in Puerto Rico for which the related deferred tax assets are not expected to be realized in future periods. The deferred tax asset realization analysis is updated at each quarter-end using the most recent forecasts. An assessment is made quarterly as to whether the forecasts and assumptions used in the deferred tax asset realization analysis should be revised in light of any changes that have occurred or are expected to occur that would significantly impact the forecasts or modeling assumptions. At December 31, 2019 , the Company has recorded the following: (in thousands) Gross Deferred Tax Balance Valuation Allowance Final Expiration Year (1) Net operating loss carryforwards $ 1,979,357 $ 165,687 2037 State net operating loss carryforwards 119,089 6,916 2039 General business credit carryforward 535,694 78,427 2038 Minimum tax credit carryforward 30,903 — N/A Capital loss carryforward 22,547 22,547 2023 Deferred tax timing differences 1,335,089 97,880 N/A Total $ 4,022,679 $ 371,457 (1) These will expire in varying amounts through the final expiration year. As of December 31, 2019 , the Company’s intention to permanently reinvest unremitted earnings of certain foreign subsidiaries (with the exception of one subsidiary) in accordance with ASC 740-30 (formerly Accounting Principles Board Opinion No. 23) remains unchanged. This will continue to be evaluated as the Company’s business needs and requirements evolve. While the TCJA included a transition tax, which amounts to a deemed repatriation of foreign earnings and a one-time inclusion of these earnings in U.S. taxable income, there could be additional costs of actual repatriation of the foreign earnings, such as state taxes and foreign withholding taxes, which are inherently difficult to quantify. Additionally, the sale of a foreign subsidiary could result in a gain that is subject to tax. The Company has not provided deferred income taxes of $28.7 million on approximately $112.1 million of the Bank's existing pre-1988 tax bad debt reserve at December 31, 2019 , due to the indefinite nature of the recapture provisions. Certain rules under Section 593 of the IRC govern when the Company may be subject to tax on the recapture of the existing base year tax bad debt reserve, such as distributions by the Bank in excess of certain earnings and profits, the redemption of the Bank’s stock, or a liquidation. The Company does not expect any of those events to occur. NOTE 15. INCOME TAXES (continued) Changes in Liability Related to Uncertain Tax Positions At December 31, 2019 , the Company had reserves related to tax benefits from uncertain tax positions of $51.3 million . A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: (in thousands) Unrecognized Tax Benefits Accrued Interest and Penalties Total Gross unrecognized tax benefits at January 1, 2017 $ 55,756 $ 43,373 $ 99,129 Additions based on tax positions related to 2017 987 — 987 Additions for tax positions of prior years 2,728 1,877 4,605 Reductions for tax positions of prior years (784 ) (1,926 ) (2,710 ) Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations (9,999 ) (1,526 ) (11,525 ) Settlements — — — Gross unrecognized tax benefits at December 31, 2017 48,688 41,798 90,486 Additions based on tax positions related to 2018 1,005 — 1,005 Additions for tax positions of prior years 2,030 1,527 3,557 Reductions for tax positions of prior years (1,545 ) (65 ) (1,610 ) Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations (4,813 ) (764 ) (5,577 ) Settlements (62 ) (29 ) (91 ) Gross unrecognized tax benefits at December 31, 2018 45,303 42,467 87,770 Additions based on tax positions related to the current year 270 — 270 Additions for tax positions of prior years 12,716 1,779 14,495 Reductions for tax positions of prior years (4,652 ) (35,554 ) (40,206 ) Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations (3,900 ) (2,134 ) (6,034 ) Settlements — — — Gross unrecognized tax benefits at December 31, 2019 $ 49,737 $ 6,558 $ 56,295 Gross net unrecognized tax benefits that if recognized would impact the effective tax rate at December 31, 2019 $ 49,737 $ 6,558 Less: Federal, state and local income tax benefits (5,023 ) Net unrecognized tax benefit reserves $ 51,272 Tax positions will initially be recognized in the financial statements when it is more likely than not that the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and all relevant facts. 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 relevant governmental taxing authorities. In establishing an income tax provision, the Company must make judgments and interpretations about the application of these inherently complex tax laws. The Company recognizes penalties and interest accrued related to unrecognized tax benefits within Income tax provision on the Consolidated Statements of Operations. 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. NOTE 15. INCOME TAXES (continued) With few exceptions, the Company is no longer subject to federal and non-U.S. income tax examinations by tax authorities for years prior to 2011 and state income tax examinations 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.

FAIR VALUE

FAIR VALUE	12 Months Ended
	Dec. 31, 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 investments in debt securities AFS 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 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. 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 Company'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. NOTE 16. FAIR VALUE (continued) 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 years ended December 31, 2019 or 2018 for any assets or liabilities valued at fair value on a recurring basis. 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 December 31, 2019 and December 31, 2018 .

(6) Approximately $281.5 million of these financial assets were measured using model-based techniques, or Level 3 inputs, and represented approximately 1.8% of total assets measured at fair value on a recurring basis and approximately 0.2% of total consolidated assets. 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: Investments in debt securities AFS Investments in debt securities 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 16. 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 which 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 reported in LHFI, net, the Company has elected the FVO. For certain of these loans, the Company has used the most recent purchase price as the fair value and hence has classified these amounts as Level 2. The fair value of the remaining RICs HFI are estimated using a 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, these remaining RICs HFI 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 Consolidated Statements of Operations through Miscellaneous income, net. See further discussion below in the section captioned "FVO for Financial Assets and Financial Liabilities." NOTE 16. 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 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 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 $5.6 million and $10.8 million , respectively, at December 31, 2019 . • A 10% and 20% increase in the discount rate would decrease the fair value of the residential servicing asset by $4.2 million and $8.3 million , respectively, at December 31, 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 16. FAIR VALUE (continued) Gains and losses related to derivatives affect various line items in the Consolidated Statements of Operations . See Note 14 to these Consolidated Financial Statements for a discussion of derivatives activity. Level 3 Rollforward for Assets and Liabilities Measured at Fair Value on a Recurring Basis The tables below present the changes in Level 3 balances for the years ended December 31, 2019 and 2018 , respectively, for those assets and liabilities measured at fair value on a recurring basis.

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 $ — $ 133,640 $ 356,220 $ 489,860 $ 5,182 $ 150,208 $ 219,258 $ 374,648 Foreclosed assets — 17,168 51,080 68,248 — 16,678 81,208 97,886 Vehicle inventory — 346,265 — 346,265 — 342,617 — 342,617 LHFS (1) — — 1,131,214 1,131,214 — — 1,073,795 1,073,795 Auto loans impaired due to bankruptcy — 200,504 503 201,007 — 189,114 — 189,114 MSRs — — 8,197 8,197 — — 9,386 9,386 (1) These amounts include $1.0 billion and $1.1 billion of personal LHFS that were impaired as of December 31, 2019 and December 31, 2018 , respectively. Valuation Processes and Techniques - Nonrecurring Fair Value Assets and Liabilities 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 $448.8 million and $479.4 million at December 31, 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. NOTE 16. FAIR VALUE (continued) 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 RIC 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 Consolidated Statements of Operations relating to assets held at period-end: Year Ended December 31, (in thousands) Statement of Operations Location 2019 2018 2017 Impaired LHFI Provision for credit losses $ (15,495 ) $ (58,818 ) $ (73,925 ) Foreclosed assets Miscellaneous income, net (1) (13,648 ) (12,137 ) (13,505 ) LHFS Provision for credit losses — (387 ) (3,700 ) LHFS Miscellaneous income, net (1) (404,606 ) (382,298 ) (386,422 ) Auto loans impaired due to bankruptcy Provision for credit losses (9,106 ) (93,277 ) (75,194 ) Goodwill impairment Impairment of goodwill — — (10,536 ) MSRs Miscellaneous income, net (1) (633 ) (743 ) (549 ) (1) Gains are disclosed as positive numbers while losses are shown as a negative number regardless of the line item being affected.

Valuation Processes and Techniques - Financial Instruments The preceding tables present disclosures about the fair value of the Company's financial instruments. Those fair values for certain instruments are presented based upon subjective estimates of relevant market conditions at a specific point in time and information about each financial instrument. In cases in which quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. These techniques involve uncertainties resulting in variability in estimates affected by changes in assumptions and risks of the financial instruments at a certain point in time. Therefore, the derived fair value estimates presented above for certain instruments cannot be substantiated by comparison to independent markets. In addition, the fair values do not reflect any premium or discount that could result from offering for sale at one time an entity’s entire holding of a particular financial instrument, nor do they reflect potential taxes and the expenses that would be incurred in an actual sale or settlement. Accordingly, the aggregate fair value amounts presented above do not represent the underlying value of the Company. The following methods and assumptions were used to estimate the fair value of each class of financial instruments not measured at fair value on the Consolidated Balance Sheets : Cash, cash equivalents and restricted cash Cash and cash equivalents include cash and due from depository institutions, interest-bearing deposits in other banks, federal funds sold, and securities purchased under agreements to resell. The related fair value measurements have been classified as Level 1, since their carrying value approximates fair value due to the short-term nature of the asset. Restricted cash is related to cash restricted for investment purposes, cash posted for collateral purposes, cash advanced for loan purchases, and lockbox collections. Cash and cash equivalents, including restricted cash, have maturities of three months or less and, accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value.

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: Year Ended December 31, (in thousands) 2019 2018 2017 (1) Non-interest income: In-scope of revenue from contracts with customers: Depository services (2) $ 241,167 $ 236,381 $ 242,995 Commission and trailer fees (3) 160,665 143,733 136,497 Interchange income, net (3) 67,524 60,258 58,525 Underwriting service fees (3) 97,211 71,536 97,143 Asset and wealth management fees (3) 145,515 138,108 112,533 Other revenue from contracts with customers (3) 39,885 36,692 40,722 Total in-scope of revenue from contracts with customers 751,967 686,708 688,415 Out-of-scope of revenue from contracts with customers: Consumer and commercial fees (4) 256,412 294,371 347,216 Lease income 2,872,857 2,375,596 2,017,775 Miscellaneous loss (4) (157,935 ) (105,650 ) (149,709 ) Net gains/(losses) on sale of investment securities 5,816 (6,717 ) (2,444 ) Total out-of-scope of revenue from contracts with customers 2,977,150 2,557,600 2,212,838 Total non-interest income $ 3,729,117 $ 3,244,308 $ 2,901,253 (1) Prior period amounts have not been adjusted under the modified retrospective method.

(3) Primarily recorded in the Company's Consolidated Statements of Operations within Miscellaneous income, net. (4) 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 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 17. NON-INTEREST INCOME AND OTHER EXPENSES (continued) Other Expenses The following table presents the Company's other expenses for the following periods: Year Ended December 31, (in thousands) 2019 (1) 2018 2017 Other expenses: Amortization of intangibles $ 58,993 $ 60,650 $ 61,491 Deposit insurance premiums and other expenses 64,734 61,983 70,661 Loss on debt extinguishment 2,735 3,470 30,349 Impairment of goodwill — — 10,536 Other administrative expenses 518,138 461,291 484,992 Other miscellaneous expenses 42,830 21,595 21,128 Total Other expenses $ 687,430 $ 608,989 $ 679,157 (1) The year ended December 31, 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.

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION	12 Months Ended

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION SC Stock Compensation Plans SC granted stock options to certain executives, other employees, and independent directors under SC's 2011 MEP, which enabled SC to make stock awards up to a total of approximately 29.4 million common shares (net of shares canceled and forfeited). The MEP expired in January 2015 and SC will not grant any further awards under the MEP. SC has granted stock options, restricted stock awards and RSUs under its Omnibus Incentive Plan (the "Plan"), which was established in 2013 and enables SC to grant awards of non-qualified and incentive stock options, stock appreciation rights, restricted stock awards, RSUs, and other awards that may be settled in or based upon the value of SC Common Stock, up to a total of 5,192,641 common shares. The Plan was amended and restated as of June 16, 2016. Stock options granted under the MEP and the Plan have an exercise price based on the estimated fair market value of SC Common Stock on the grant date. The stock options expire ten years after grant date and include both time vesting options and performance vesting options. The fair value of the stock options is amortized into income over the vesting period as time and performance vesting conditions are met. In 2013, the SC Board approved certain changes to the MEP, including acceleration of vesting for certain employees, removal of transfer restrictions for shares underlying a portion of the options outstanding, and addition of transfer restrictions for shares underlying another portion of the outstanding options. All of the changes were contingent on, and effective upon, SC's execution of an IPO and, as such, became effective upon pricing of SC's IPO on January 22, 2014. Compensation expense related to 583,890 shares of restricted stock that SC has issued to certain executives is recognized over a five -year vesting period, with zero , zero , and $5.5 million recorded for the years ended December 31, 2019 , 2018 and 2017 , respectively. SC recognized $8.6 million , $7.7 million and $13.0 million related to stock options and RSUs within compensation expense for the years ended December 31, 2019, 2018 and 2017, respectively. In addition, SC recognizes forfeitures of awards as they occur. Also in connection with its IPO, SC granted additional stock options under the MEP to certain executives, other employees, and an independent director with an estimated compensation cost of $10.2 million , which is being recognized over the awards' vesting period of five years for the employees and three years for the director. Additional stock option grants were made to employees under the Plan during the year ended December 31, 2016. The estimated compensation cost associated with these additional grants was $0.7 million and will be recognized over the vesting periods of the awards. The grant date fair values of these stock option awards were determined using the Black-Scholes option valuation model. NOTE 18. STOCK-BASED COMPENSATION (continued) A summary of SC's stock options and related activity as of and for the year ended December 31, 2019 , is as follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (in whole dollars) (in 000's) Options outstanding at January 1, 2019 645,376 $ 13.15 4.0 $ 3,682 Granted — — Exercised (356,183 ) 12.72 4,266 Expired (1,480 ) 9.21 Forfeited (15,456 ) 24.36 Other 1,480 9.21 Options outstanding at December 31, 2019 273,737 $ 13.09 3.1 $ 2,867 Options exercisable at December 31, 2019 243,786 $ 12.57 2.8 $ 2,674 Options expected to vest after December 31, 2019 29,951 $ 17.26 5.8 $ 193 A summary of the status and changes of SC's nonvested stock options as of and for the year ended December 31, 2019 , is presented below: Shares Weighted Average Grant Date Fair Value Non-vested at January 1, 2019 87,821 $ 6.55 Granted — — Vested (42,414 ) 7.08 Forfeited (15,456 ) 8.09 Non-vested at December 31, 2019 29,951 $ 5.01 At December 31, 2019 , total unrecognized compensation expense for nonvested stock options was $72.0 thousand , which is expected to be recognized over a weighted average period of 0.8 years . There were no stock options were granted to employees in 2019 or 2018. The Company has the same fair value basis with that of SC for any stock option awards after the IPO date. In connection with compensation restrictions imposed on certain executive officers and other employees by the European Central Bank under the CRD IV prudential rules, which require a portion of such officers' and employees' variable compensation to be paid in the form of equity and deferred, SC periodically grants RSUs. Under the Plan, a portion of these RSUs vested immediately upon grant, and a portion will vest annually over the following three or five years subject to the achievement of certain performance conditions as and where applicable. After the shares subject to the RSUs vest and are settled, they are subject to transfer and sale restrictions for one year . RSUs are valued based upon the fair market value on the date of the grant. A summary of the Company’s RSUs and performance stock units and related activity as of and for the year ended December 31, 2019 is as follows: Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (in whole dollars) (in 000's) Outstanding at January 1, 2019 698,799 $ 14.53 1.1 $ 12,292 Granted 473,325 20.46 Vested (563,427 ) 16.69 11,882 Forfeited/cancelled (110,398 ) 16.34 Unvested at December 31, 2019 498,299 $ 17.41 0.9 $ 11,645

Retirement Benefits [Abstract]
OTHER EMPLOYEE BENEFIT PLANS	OTHER EMPLOYEE BENEFIT PLANS Defined Contribution Plans All employees of the Bank are eligible to participate in the 401(k) Plan, sponsored by the Company, following their completion of one month of service. There is no age requirement to join the 401(k) Plan. Beginning January 2019, the Bank matched 100% of employee contributions up to 5% of their compensation. Prior to 2019, the Bank matched 100% of employee contributions up to 4% of the employee's compensation and then 50% of employee contributions between 3% and 5% of their compensation. The Bank's match is immediately vested and is allocated to the employee’s various 401(k) Plan investment options in the same percentages as the employee’s own contributions. The Bank recognized expense for contributions to the 401(k) Plan of $33.7 million , $26.8 million and $20.6 million during 2019 , 2018 and 2017 , respectively, within the Compensation and benefits line on the Consolidated Statements of Operations. Beginning January 2020, the Bank will match 100% of employee contributions up to 6% of the employee's compensation. SC sponsors a defined contribution plan offered to qualifying employees. Employees participating in the plan may contribute up to 75% of their eligible compensation, subject to federal limitations on absolute amounts contributed. SC will match up to 6% of their eligible compensation, with matching contributions of up to 100% of employee contributions. The total amount contributed by SC under this plan in 2019 , 2018 and 2017 was $14.0 million , $14.0 million and $12.4 million , respectively. Defined Benefit Plans and Other Post Retirement Benefit Plans The Company sponsors several defined benefit plans and other post-retirement benefit plans that cover certain employees. All of these plans are frozen and therefore closed to new entrants; all benefits are fully vested, and therefore the plans ceased accruing benefits. The Company complies with minimum funding requirements in all countries. The Company also sponsors several supplemental executive retirement plans and other unfunded post-retirement benefit plans that provide health care to certain retired employees. The Company recognizes the funded status of its defined benefit pension plans and other post-retirement benefit plans, measured as the difference between the fair value of the plan assets and the projected benefit obligation, within Other liabilities on the Consolidated Balance Sheets. The Company has accrued liabilities of $31.5 million and $29.0 million related to its total defined benefit pension plans and other post-retirement benefit plans at December 31, 2019 and December 31, 2018 , respectively. The net unfunded status related to actuarially-valued defined benefit pension plans and other post-retirement plans was $14.5 million and $13.5 million at December 31, 2019 and December 31, 2018 , respectively. BSI and SIS are participating employers in a defined benefit pension plan sponsored by Santander's New York branch, covering certain active and former BSI and SIS employees. Effective December 31, 2012, the defined benefit pension plan was frozen. The amounts representing BSI and SIS's share of the pension liability are recorded within Other liabilities on the Consolidated Balance Sheet as of December 31, 2019 and December 31, 2018 . This plan currently has an unfunded liability of $47.0 million , of which $28.5 million is BSI and SIS's share of the liability.

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 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 14 to these Consolidated Financial Statements for discussion of all derivative contract commitments. NOTE 20. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) The following table details the amount of commitments at the dates indicated: Other Commitments December 31, 2019 December 31, 2018 (in thousands) Commitments to extend credit $ 30,685,478 $ 30,269,311 Letters of credit 1,592,726 1,488,714 Commitments to sell loans 21,341 875 Unsecured revolving lines of credit 24,922 28,145 Recourse exposure on sold loans 53,667 49,733 Total commitments $ 32,378,134 $ 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. Included within the reported balances for Commitments to extend credit at December 31, 2019 and December 31, 2018 are $5.7 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 December 31, 2019 was 16.8 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 December 31, 2019 was $1.6 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 December 31, 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 December 31, 2019 and December 31, 2018 , the liability related to these letters of credit was $4.9 million and $4.6 million , respectively, which is recorded within the reserve for unfunded lending commitments in Other liabilities on the 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 December 31, 2019 and December 31, 2018 was the liability related to lines of credit outstanding of $84.7 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. NOTE 20. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) 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 . SC Commitments The following table summarizes liabilities recorded for commitments and contingencies as of December 31, 2019 and December 31, 2018 , all of which are included in Accounts payable and accrued expenses in the accompanying Consolidated Balance Sheet s: Agreement or Legal Matter Commitment or Contingency December 31, 2019 December 31, 2018 (in thousands) Chrysler Agreement Revenue-sharing and gain/(loss), net-sharing payments $ 12,132 $ 7,001 Agreement with Bank of America Servicer performance fee 2,503 6,353 Agreement with CBP Loss-sharing payments 1,429 3,708 Other contingencies Consumer arrangements 1,991 2,138 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 the terms of that 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 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 $2.0 million , and $2.1 million at December 31, 2019 and December 31, 2018 , respectively, for other miscellaneous contingencies. NOTE 20. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) 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 December 31, 2019 and December 31, 2018 , the total unused credit available to customers was $3.0 billion and $3.1 billion , respectively. In 2019, SC purchased $1.2 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 $270.4 million and $304.6 million of receivables related to newly-opened customer accounts during the years ended December 31, 2019 and 2018 , respectively. Each customer account generated under the agreements generally is approved with a credit limit higher than the amount of the initial purchase, with each subsequent purchase automatically approved as long as it does not cause the account to exceed its limit and the customer is in good standing. As of December 31, 2019 and December 31, 2018 , SC was obligated to purchase $10.6 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. SC is currently seeking a third party to assume its obligations under its agreement with Bluestem; however, SC may not be successful in finding such a party, and Bluestem may not agree to the substitution. Until SC finds a third party to assume its obligations under the agreement, there is a risk that material changes to SC’s relationship with Bluestem, or the loss or discontinuance of Bluestem’s business, would materially and adversely affect SC’s business, financial condition and results of operations. 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 December 31, 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 December 31, 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. NOTE 20. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) Legal and Regulatory Proceedings The Company, including its subsidiaries, is and in the future expects to be party to, or otherwise involved in or subject to, various claims, disputes, lawsuits, investigations, regulatory matters and other legal matters and proceedings that arise in the ordinary course of business. In view of the inherent difficulty of predicting the outcome of any such dispute, 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, if any. Accordingly, except as provided below, the Company is unable to reasonably estimate a range of its potential exposure, if any, to these claims, disputes, lawsuits, investigations, regulatory matters and other legal proceedings at this time. 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 claims, 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 claim, dispute, 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 December 31, 2019 and December 31, 2018 , the Company accrued aggregate legal and regulatory liabilities of $294.7 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 $144.4 million as of December 31, 2019 . Set forth below are descriptions of the material lawsuits, regulatory matters and other legal proceedings to which the Company is subject. SHUSA Matter 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 Chase, Chase has asserted an indemnity claim against SBNA of approximately $38.0 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 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. NOTE 20. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) 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 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. On March 23, 2018, the Feldman Lawsuit and Jackie888 Lawsuit were consolidated under the caption In Re Santander Consumer USA Holdings, Inc. Derivative Litigation , Del. Ch., Consol. C.A. No. 11614-VCG. On January 21, 2020, the Company executed a Stipulation and Agreement of Settlement, Compromise and Release with the plaintiffs in the consolidated action that fully resolves all of the claims of plaintiffs on the Feldman Lawsuit and the Jackie888 Lawsuit. The Stipulation provides for the settlement of the consolidated action in return for defendants causing SC to enact and implement certain corporate governance reforms and enhancements. The settlement is subject to approval by the Court. 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 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 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 the 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 CIDs from the Attorneys General of California, Illinois, Oregon, New Jersey, Maryland and Washington under the authority of each state's consumer protection statutes. These states 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, 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. NOTE 20. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) Mississippi Attorney General Lawsuit In January 2017, 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. 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 provided 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 FINRA arbitration actions and class action claims. Puerto Rico FINRA Arbitration As of December 31, 2019 , SSLLC had received 751 FINRA arbitration cases related to Puerto Rico bonds and Puerto Rico 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 439 arbitration cases pending as of December 31, 2019 . The Company has experienced a decrease in the volume of claims since September 30, 2019; however, it is reasonably possible that 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. NOTE 20. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) Mexican Government Bonds Consolidated Putative Antitrust Class Action : A consolidated putative 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 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. On December 9, 2019, the plaintiffs filed an amended putative class action complaint. The amended complaint does not name the Company or SIS as defendants; the only Santander defendant named in the amended complaint is Banco Santander (Mexico). 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.

REGULATORY MATTERS

REGULATORY MATTERS	12 Months Ended
	Dec. 31, 2019
Banking and Thrift [Abstract]
REGULATORY MATTERS	REGULATORY MATTERS The Company is subject to the regulations of certain federal, state, and foreign agencies, and undergoes periodic examinations by such regulatory authorities. The minimum U.S. regulatory capital ratios for banks under Basel III are 4.5% for the CET1 capital ratio, 6.0% for the Tier 1 capital ratio, 8.0% for the total capital ratio, and 4.0% for the leverage ratio. To qualify as “well-capitalized,” regulators require banks to maintain capital ratios of at least 6.5% for the CET1 capital ratio, 8.0% for the Tier 1 capital ratio, 10.0% for the total capital ratio, and 5.0% for the leverage ratio. At December 31, 2019 and 2018 , the Bank met the well-capitalized capital ratio requirements. As a BHC, SHUSA is required to maintain a CET1 capital ratio of at least 4.5% , Tier 1 capital ratio of at least 6.0% , total capital ratio of at least 8.0% , and Leverage ratio of at least 4.0% . The Company’s capital levels exceeded the ratios required for BHCs. The Company's ability to make capital distributions will depend on the Federal Reserve's accepting the Company's capital plan, the results of the stress tests described in this Form 10-K, and the Company's capital status, as well as other supervisory factors. The DFA mandates an enhanced supervisory framework, which, among other things, means that the Company is subject to both internal and Federal Reserve run stress tests. The Federal Reserve also has discretionary authority to establish additional prudential standards, on its own or at the Financial Stability Oversight Council's recommendation, regarding contingent capital, enhanced public disclosures, short-term debt limits, and otherwise as it deems appropriate. The Company is also required to receive a notice of non-objection to its capital plans from the Federal Reserve and the OCC before taking capital actions, such as paying dividends, implementing common equity repurchase programs, or redeeming or repurchasing capital instruments. For a discussion of Basel III and the standardized approach and related future changes to the minimum U.S. regulatory capital ratios, see the section of the MD&A captioned "Regulatory Matters." NOTE 22. REGULATORY MATTERS (continued) The Federal Deposit Insurance Corporation Improvement Act established five capital tiers: well-capitalized, adequately-capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. A depository institution’s capital tier depends on its capital levels in relation to various capital measures, which include leverage and risk-based capital measures and certain other factors. Depository institutions that are not classified as well-capitalized or adequately-capitalized are subject to various restrictions regarding capital distributions, payment of management fees, acceptance of brokered deposits and other operating activities. Federal banking laws, regulations and policies also limit the Bank’s ability to pay dividends and make other distributions to the Company. The Bank must obtain prior OCC approval to declare a dividend or make any other capital distribution if, after such dividend or distribution: (1) the Bank’s total distributions to SHUSA within that calendar year would exceed 100% of its net income during the year plus retained net income for the prior two years ; (2) the Bank would not meet capital levels imposed by the OCC in connection with any order, or (3) the Bank is not adequately capitalized at the time. The OCC's prior approval would be required if the Bank is notified by the OCC that it is a problem institution or in troubled condition. Any dividend declared and paid or return of capital has the effect of reducing capital ratios. During 2019 , 2018 , and 2017 the Company paid cash dividends of $400.0 million , $410.0 million and $10.0 million , respectively. During 2019 , 2018 and 2017 , the Company also paid cash dividends to preferred shareholders of zero , $11.0 million and $14.6 million , respectively. During the third quarter of 2018, SHUSA redeemed all of its outstanding preferred stock. The following schedule summarizes the actual capital balances of the Bank and SHUSA at December 31, 2019 and 2018 : REGULATORY CAPITAL (Dollars in thousands) Common Equity Tier 1 Capital Ratio Tier 1 Capital Total Capital Leverage SBNA at December 31, 2019 (1) : Regulatory capital $ 10,219,819 $ 10,219,819 $ 10,844,218 $ 10,219,819 Capital ratio 15.80 % 15.80 % 16.77 % 12.77 % SHUSA at December 31, 2019 (1) : Regulatory capital $ 17,391,867 $ 18,780,870 $ 20,480,467 $ 18,780,870 Capital ratio 14.63 % 15.80 % 17.23 % 13.13 % Common Equity Tier 1 Capital Ratio Tier 1 Capital Total Capital Leverage SBNA at December 31, 2018 (1) : Regulatory capital $ 10,179,299 $ 10,179,299 $ 10,819,641 $ 10,179,299 Capital ratio 17.14 % 17.14 % 18.22 % 14.08 % SHUSA at December 31, 2018 (1) : Regulatory capital $ 16,758,748 $ 18,193,361 $ 19,807,403 $ 18,193,361 Capital ratio 15.53 % 16.86 % 18.35 % 14.03 % (1) Represents transitional ratios under Basel III.

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 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 & VF. All prior period results have been recast to conform to the new composition of reportable segments. NOTE 23. BUSINESS SEGMENT INFORMATION (continued) 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. • 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 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 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. NOTE 23. BUSINESS SEGMENT INFORMATION (continued) 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 below 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.

BASIS OF PRESENTATION AND ACC_2

BASIS OF PRESENTATION AND ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These 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 VOEs in which the Company has a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. These Consolidated Financial Statements have been prepared in accordance with GAAP and pursuant to SEC regulations. 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 Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary for a fair statement of the Consolidated Balance Sheets , Statements of Operations , Statements of Comprehensive Income , Statements of Stockholder's Equity and SCF for the periods indicated, and contain adequate disclosure of this interim financial information to make the information presented not misleading. Certain prior-year amounts have been reclassified to conform to the current year presentation. These reclassifications did not have a material impact on the Company's consolidated financial condition or results of operations.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates, and those differences may be material. The most significant estimates pertain to fair value measurements, the ALLL and reserve for unfunded lending commitments, accretion of discounts and subvention on RICs, estimates of expected residual values of leased vehicles subject to operating leases, goodwill, and income taxes. Actual results may differ from the estimates, and the differences may be material to the Consolidated Financial Statements.
Recently Adopted Accounting Standards and Recent Accounting Developments	Recently Adopted Accounting Standards Since January 1, 2019, the Company adopted the following FASB ASUs: • ASU 2016-02, Leases (Topic 842) . The Company adopted this standard as of January 1, 2019, resulting in the recognition of a 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. 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 2018-15, 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. • 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 measured at amortized cost. The amendment introduces a new credit reserving framework known as CECL, which replaces the incurred loss impairment framework in current GAAP with one that reflects expected credit losses over the full expected life of financial assets and commitments, and requires consideration of a broader range of reasonable and supportable information, including estimation of future expected changes in macroeconomic conditions. Additionally, the standard changes the accounting framework for purchased credit-deteriorated HTM debt securities and loans, and dictates measurement of AFS debt securities using an allowance instead of reducing the carrying amount as it is under the current OTTI framework. The Company adopted the new guidance on January 1, 2020. The Company established a cross-functional working group for implementation of this standard. Generally, our implementation process included data sourcing and validation, development and validation of loss forecasting methodologies and models, including determining the length of the reasonable and supportable forecast period and selecting macroeconomic forecasting methodologies to comply with the new guidance, updating the design of our established governance, financial reporting, and internal control over financial reporting frameworks, and updating accounting policies and procedures. The status of our implementation was periodically presented to the Audit Committee and the Risk Committee. The Company completed multiple parallel model runs to test and refine its current expected credit loss models to satisfy the requirements of the new standard. The adoption of this standard resulted in the increase in the ACL of approximately $2.5 billion and a decrease to opening retained earnings, net of income taxes, at January 1, 2020. The estimated increase is based on forecasts of expected future economic conditions and is primarily driven by the fact that the allowance will cover expected credit losses over the full expected life of the loan portfolios. The standard did not have a material impact on the Company’s other financial instruments. Additionally, we elected to utilize regulatory relief which will permit us to phase in 25 percent of the capital impact of CECL in our calculation of regulatory capital amounts and ratios in 2020, and an additional 25 percent each subsequent year until fully phased-in by the first quarter of 2023. 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. The Company adopted the new guidance effective January 1, 2020 and it did not have a material impact on the Company’s business, financial position or results of operations. In addition to those described in detail above, on January 1, 2020, the Company adopted ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities , and it did not have a material impact on the Company's business, financial position, results of operations, or disclosures.
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. 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. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) 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.
Consolidation	Consolidation In accordance with the applicable accounting guidance for consolidations, the Consolidated Financial Statements include any VOEs in which the Company has a controlling financial interest and any VIEs for which the Company is deemed to be the primary beneficiary. The Company consolidates its VIEs if the Company has (i) a variable interest in the entity; (ii) the power to direct activities of the VIE that most significantly impact the entity's economic performance; and (iii) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE (i.e., the Company is considered to be the primary beneficiary). The Company generally consolidates its VOEs if the Company, directly or indirectly, owns more than 50% of the outstanding voting shares of the entity and the noncontrolling shareholders do not hold any substantive participating or controlling rights. Interests in VIEs and VOEs can include equity interests in corporations, partnerships and similar legal entities, subordinated debt, securitizations, derivatives contracts, leases, service agreements, guarantees, standby letters of credit, loan commitments, and other contracts, agreements and financial instruments. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Upon the occurrence of certain significant events, as required by the VIE model, the Company reassesses whether a legal entity in which the Company is involved is a VIE. The reassessment process considers whether the Company has acquired or divested the power to direct the activities of the VIE through changes in governing documents or other circumstances. The reassessment also considers whether the Company has acquired or disposed of a financial interest that could be significant to the VIE, or whether an interest in the VIE has become significant or is no longer significant. The consolidation status of the entities with which the Company is involved may change as a result of such reassessments. Changes in consolidation status are applied prospectively, with assets and liabilities of a newly consolidated VIE initially recorded at fair value. A gain or loss may be recognized upon deconsolidation of a VIE, depending on the carrying amounts of deconsolidated assets and liabilities compared to the fair value of retained interests and ongoing contractual arrangements. The Company uses the equity method to account for unconsolidated investments in VOEs if the Company has significant influence over the entity's operating and financing decisions but does not maintain a controlling financial interest. Unconsolidated investments in VOEs or VIEs in which the Company has a voting or economic interest of less than 20% generally are carried at cost less any impairment. These investments are included in Other assets on the Consolidated Balance Sheets, and the Company's proportionate share of income or loss is included in Miscellaneous income, net within the Consolidated Statements of Operations.
Sale of RICs and Leases	Sales of RICs and Leases The Company, through SC, transfers RICs into newly formed Trusts which then issue one or more classes of notes payable backed by the RICs. The Company’s continuing involvement with the credit facilities and Trusts are in the form of servicing loans held by the SPEs and, generally, through holding a residual interest in the SPE. These transactions are structured without recourse. The Trusts are considered VIEs under GAAP and are consolidated when the Company has: (a) power over the significant activities of the entity and (b) an obligation to absorb losses or the right to receive benefits from the VIE which are potentially significant to the VIE. The Company has power over the significant activities of those Trusts as servicer of the financial assets held in the Trust. Servicing fees are not considered significant variable interests in the Trusts; however, when the Company also retains a residual interest in the Trust, either in the form of a debt security or equity interest, the Company has an obligation to absorb losses or the right to receive benefits that are potentially significant to the SPE. Accordingly, these Trusts are consolidated within the Consolidated Financial Statements, and the associated RICs, borrowings under credit facilities and securitization notes payable remain on the Consolidated Balance Sheets. Securitizations involving Trusts in which the Company does not retain a residual interest or any other debt or equity interest are treated as sales of the associated RICs. While these Trusts are included in our Consolidated Financial Statements, they are separate legal entities; thus, the finance receivables and other assets sold to these Trusts are legally owned by the Trusts, are available only to satisfy the notes payable related to the securitized RICs, and are not available to the Company's creditors or other subsidiaries. The Company also sells RICs and leases to VIEs or directly to third parties. The Company may determine that these transactions meet sale accounting treatment in accordance with applicable guidance. Due to the nature, purpose, and activity of these transactions, the Company either does not hold potentially significant variable interests or is not the primary beneficiary as a result of the Company's limited further involvement with the financial assets. The transferred financial assets are removed from the Company's Consolidated Balance Sheets at the time the sale is completed. The Company generally remains the servicer of the financial assets and receives servicing fees. The Company also recognizes a gain or loss for the difference between the fair value, as measured based on sales proceeds plus (or minus) the value of any servicing asset (or liability) retained and the carrying value of the assets sold.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents, and Restricted Cash Cash and cash equivalents include cash and amounts due from depository institutions, interest-bearing deposits in other banks, federal funds sold, and securities purchased under agreements to resell. Cash and cash equivalents have original maturities of three months or less and, accordingly, the carrying amount of these instruments is deemed to be a reasonable estimate of fair value. The Company has maintained balances in various operating and money market accounts in excess of federally insured limits. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Cash deposited to support securitization transactions, lockbox collections, and the related required reserve accounts is recorded in the Company's Consolidated Balance Sheets as restricted cash. Excess cash flows generated by Trusts are added to the restricted cash reserve account, creating additional over-collateralization until the contractual securitization requirement has been reached. Once the targeted reserve requirement is satisfied, additional excess cash flows generated by the Trusts are released to the Company as distributions from the Trusts. Lockbox collections are added to restricted cash and released when transferred to the appropriate warehouse facility or Trust. The Company also maintains restricted cash primarily related to cash posted as collateral related to derivative agreements and cash restricted for investment purposes.
Investment Securities and Other Investments	Investment Securities and Other Investments Investment in debt securities are classified as either AFS, HTM, trading, or other investments. Investments in equity securities are generally recorded at fair value with changes recorded in earnings. Management determines the appropriate classification at the time of purchase. Debt securities expected to be held for an indefinite period of time are classified as AFS and are carried at fair value, with temporary unrealized gains and losses reported as a component of accumulated other comprehensive income within stockholder's equity, net of estimated income taxes. Debt securities purchased which the Company has the positive intent and ability to hold until maturity are classified as HTM securities. HTM securities are reported at cost and adjusted for payments, amortization of premium and accretion of discount. Transfers of debt securities into the HTM category from the AFS category are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in OCI and in the carrying value of the HTM securities. Such amounts are amortized over the remaining lives of the securities. The Company conducts a comprehensive security-level impairment assessment quarterly on all securities with a fair value that is less than their amortized cost basis to determine whether the loss represents OTTI. The quarterly OTTI assessment takes into consideration whether (i) the Company has the intent to sell or, (ii) it is more likely than not that it will be required to sell the security before the expected recovery of its amortized cost. The Company also considers whether or not it would expect to receive all of the contractual cash flows from the investment based on its assessment of the security structure, recent security collateral performance metrics, external credit ratings, failure of the issuer to make scheduled interest or principal payments, judgment and expectations of future performance, and relevant independent industry research, analysis and forecasts. The Company also considers the severity of the impairment in its assessment. In the event of a credit loss, the credit component of the impairment is recognized within non-interest income as a separate line item, and the non-credit component is recorded within accumulated OCI. Realized gains and losses on sales of investment securities are recognized on the trade date and included in earnings within Net (losses)/gains on sale of investment securities, which is a component of non-interest income. Unamortized premiums and discounts are recognized in interest income over the estimated life of the security using the interest method. Debt securities held for trading purposes and equity securities are carried at fair value, with changes in fair value recorded in non-interest income. Investments that are purchased principally for the purpose of economically hedging the MSR in the near term are classified as trading securities and carried at fair value, with changes in fair value recorded as a component of the Miscellaneous income, net line of the Consolidated Statements of Operations. Other investments primarily include the Company's investment in the stock of the FHLB of Pittsburgh and the FRB. Although FHLB and FRB stock are equity interests in the FHLB and FRB, respectively, neither has a readily determinable fair value, because ownership is restricted and they are not readily marketable. FHLB stock can be sold back only at its par value of $100 per share and only to FHLBs or to another member institution. Accordingly, FHLB stock and FRB stock are carried at cost. The Company evaluates this investment for impairment on the ultimate recoverability of the par value rather than by recognizing temporary declines in value.
LHFI	LHFI LHFI include commercial and consumer loans (including RICs) originated by the Company as well as loans acquired by the Company, which the Company intends to hold for the foreseeable future or until maturity. RICs consist largely of nonprime automobile finance receivables that are acquired individually from dealers at a nonrefundable discount from the contractual principal amount. RICs also include receivables originated through a direct lending program and loan portfolios purchased from other lenders. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Originated LHFI Originated LHFI are reported net of cumulative charge offs, unamortized loan origination fees and costs, and unamortized discounts and premiums. Interest on loans is credited to income as it is earned. For most of the Company's originated LHFI, loan origination fees and certain direct loan origination costs and premiums and discounts are deferred and recognized as adjustments to interest income in the Consolidated Statements of Operations over the contractual life of the loan utilizing the effective interest method. For RICs, loan origination fees and costs, premiums and discounts are deferred and amortized over their estimated lives as adjustments to interest income utilizing the effective interest method using estimated prepayment speeds, which are updated on a monthly basis. The Company estimates future principal prepayments specific to pools of homogeneous loans, which are based on the vintage, credit quality at origination and term of the loan. Prepayments in our portfolio are sensitive to credit quality, with higher credit quality loans experiencing higher voluntary prepayment rates than lower credit quality loans. The resulting prepayment rate specific to each pool is based on historical experience and is used as an input in the calculation of the constant effective yield. The impact of defaults is not considered in the prepayment rate; the prepayment rate only considers voluntary prepayments. Our estimated weighted average prepayment rates ranged from 5.1% to 11.0% at December 31, 2019 and 5.7% to 10.8% at December 31, 2018 . The Company’s LHFI are carried at amortized cost, net of the ALLL. When a RIC is originated, certain cost basis adjustments (the net discounts) to the principal balance of the loan are recognized in accordance with the accounting guidance for loan origination fees and costs in ASC 310-20. These cost basis adjustments generally include the following: • Origination costs. • Dealer discounts - dealer discounts to the principal balance of the loan generally occur in circumstances in which the contractual interest rate on the loan is not sufficient to compensate for the credit risk of the borrower. • Participation - participation fees, or premiums, paid to the dealer as a form of profit-sharing, rewarding the dealer for originating loans that perform. • Subvention - payments received from the vehicle manufacturer as compensation (yield enhancement) for the cost of below-market interest rates offered to consumers. Originated loans are initially recorded at the proceeds paid to fund the loan. Loan origination fees and costs and any discount at origination for loans is considered by the Company to reflect yield enhancements and is accreted to income using the effective interest method. See LHFS subsection below for accounting treatment when an HFI loan is re-designated as LHFS. Purchased LHFI Purchased loans are generally loans acquired in a bulk purchase or business combination. RICs acquired directly from a dealer are considered to be originated loans, not purchased loans. Purchase discounts and premiums on purchased loans that are deemed performing are accreted over the remaining expected lives of the loans to their par values, generally using the retrospective effective interest method, which considers the impact of estimated prepayments that is updated on a quarterly basis. The purchase discount on personal unsecured loans (given their revolving nature) are amortized on a straight-line basis in accordance with ASC 310-20. Purchased loans with evidence of credit quality deterioration as of the purchase date for which it is probable that the Company will not receive all contractually required payments receivable are accounted for as PCI loans. At acquisition, PCI loans are recorded at fair value with no allowance for credit losses, and accounted for individually or aggregated in pools based on similar risk characteristics. The Company estimates the amount and timing of expected cash flows for each loan or pool of loans. The expected cash flows in excess of the amount paid for the loans is referred to as the accretable yield and is recorded as interest income over the remaining estimated life of the loan or pool of loans. The Company may irrevocably elect to account for certain loans acquired with evidence of credit deterioration at fair value in accordance with ASC 825. Accordingly, the Company does not recognize interest income for these loans and recognizes the fair value adjustments on these loans as part of other non-interest income in the Company’s Consolidated Statements of Operations. For certain loans which the Company has elected to account for at fair value that are not considered non-accrual, the Company separately recognizes interest income from the total fair value adjustment. No ALLL is recognized for loans that the Company has elected to account for at fair value.
ALLL for Loans Losses and Reserve for Unfunded Lending Commitments	ALLL for Loan Losses and Reserve for Unfunded Lending Commitments The ALLL and reserve for unfunded lending commitments (together, the ACL) are maintained at levels that management considers adequate to provide for losses on the recorded investment of the loan portfolio, based upon an evaluation of known and inherent risks in the loan portfolio. Management's evaluation takes into consideration the risks in the loan portfolio, past loan and lease loss experience, specific loans with loss potential, geographic and industry concentrations, delinquency trends, economic conditions and other relevant factors. While management uses the best information available to make such evaluations, future adjustments to the ACL may be necessary if conditions differ substantially from the assumptions used in making the evaluations. The ALLL consists of two elements: (i) an allocated allowance, which is comprised of allowances established on loans specifically evaluated for impairment, and loans collectively evaluated for impairment, based on historical loan and lease loss experience adjusted for current trends and both general economic conditions and other risk factors in the Company's loan portfolios, and (ii) an unallocated allowance to account for a level of imprecision in management's estimation process. Reserve levels are collectively reviewed for adequacy and approved quarterly by Board-level committees. The ALLL includes the estimate of credit losses that management expects will be realized during the loss emergence period, including the amount of net discounts that is included in the loans' recorded investment at the time of charge-off. In the case of loans purchased in a bulk purchase or business combination, the entire discount on the loan portfolio is considered as available to absorb the credit losses when determining the ALLL. For these loans, the Company records provisions for credit losses when incurred losses exceed the unaccreted purchase discount. Provisions for credit losses are charged to provision expense in amounts sufficient to maintain the ACL at levels considered adequate to cover probable credit losses incurred in the Company’s HFI loan portfolios. The Company uses the incurred loss approach in providing an ACL on the recorded investment of its existing loans. This approach requires that loan loss provisions are recognized and the corresponding allowance recorded when, based on all available information, it is probable that a credit loss has been incurred. The estimate for credit losses for loans that are individually evaluated for impairment is generally determined through an analysis of the present value of the loan’s expected future cash flows, except for those that are deemed to be collateral dependent. For those loans that are collectively assessed for impairment, the Company utilizes historical loan loss experience information as part of its evaluation. In addition, when establishing the collective ACL for originated loans, the Company’s estimate of losses on recorded investment includes the estimate of the related net discount balance that is expected at the time of charge-off. Although the ACL is established on a collective basis, actual charge-offs are recorded on a loan-by-loan basis when losses are confirmed or when established delinquency thresholds have been met. Additional discussions related to the Company’s charge-off policies are provided in the “Charge-offs of Uncollectible Loans” section below . When a loan in any portfolio or class has been determined to be impaired (e.g., TDRs and non-accrual commercial loans in excess of $1 million ) as of the balance sheet date, the Company measures impairment based on the present value of expected future cash flows discounted at the loan's original effective interest rate. However, as a practical expedient, the Company may measure impairment based on a loan's observable market price, or the fair value of the collateral less costs to sell if the loan is a collateral-dependent loan. A specific reserve is established as a component of ACL for these impaired loans. Subsequent to the initial measurement of impairment, if there is a significant change to the impaired loan’s expected future cash flows (including the fair value of the collateral for collateral dependent loans) the Company recalculates the impairment and adjusts the specific reserve. Some impaired loans have risk characteristics similar to other impaired loans and may be aggregated for the measurement of impairment. For those impaired loans that are collectively assessed for impairment, the Company utilizes historical loan loss experience information as part of its evaluation. When the Company determines that the present value of the estimated cash flows of an impaired loan is less than its carrying amount, the Company recognizes impairment through a provision estimate or a charge-off to the allowance. Management performs these assessments on at least a quarterly basis. The Company's allocated reserves are principally based on its various models subject to the Company's model risk management framework. New models are approved by the Company's Model Risk Management Committee, and inputs are reviewed periodically by the Company's internal audit function. Models, inputs and documentation are further reviewed and validated at least annually, and the Company completes a detailed variance analysis of historical model projections against actual observed results on a quarterly basis. Required actions resulting from the Company's analysis, if necessary, are governed by its Allowance for Loan and Lease Losses Committee. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) The Company's unallocated allowance is no more than 5% of the overall allowance. This is considered to be reasonably sufficient to absorb imprecisions of models to otherwise provide for coverage of inherent losses in the Company's entire loan and lease portfolio. Imprecisions include loss factors inherent in the loan portfolio that may not have been discreetly contemplated in the general and specific components of the allowance, as well as potential variability in estimates. The unallocated allowance is also established in consideration of several factors such as inherent delays in obtaining information regarding a customer's financial condition or changes in its unique business conditions and the interpretation of economic trends. While this analysis is conducted at least quarterly, the Company has the ability to revise the allowance factors whenever necessary in order to address improving or deteriorating credit quality trends or specific risks associated with a loan pool classification. Regardless of the extent of the Company's analysis of customer performance, portfolio evaluations, trends or risk management processes established, a level of imprecision will always exist due to the judgmental nature of loan portfolio and/or individual loan evaluations. The Company maintains an unallocated allowance to recognize the existence of these exposures. For the commercial loan portfolio segment, the Company has specialized credit officers and workout units that identify and manage potential problem loans. Changes in management factors, financial and operating performance, company behavior, industry factors and external events and circumstances are evaluated on an ongoing basis to determine whether potential impairment is evident and additional analysis is needed. For the commercial loan portfolio segment, risk ratings are assigned to each loan to differentiate risk within the portfolio, and are reviewed on an ongoing basis by Credit Risk Management and revised, if needed, to reflect the borrower's current risk profile and the related collateral positions. The risk ratings consider factors such as financial condition, debt capacity and coverage ratios, market presence and quality of management. Generally, credit officers reassess a borrower's risk rating on no less than an annual basis, and more frequently if warranted. This reassessment process is managed on a continual basis by the Credit Risk Review group to ensure consistency and accuracy in risk ratings as well as appropriate frequency of risk rating review by the Company's credit officers. The Company's Credit Risk Review group regularly performs loan reviews and assesses the appropriateness of assigned risk ratings. When a loan's risk rating is downgraded beyond a certain level, the Company's Workout Department becomes responsible for managing the credit risk. Risk rating actions are generally reviewed formally by one or more credit committees, depending on the size of the loan and the type of risk rating action being taken. Detailed analyses are completed that support the risk rating and management's strategies for the customer relationship going forward. The consumer loan portfolio segment and small business loans are monitored for credit risk and deterioration with statistical tools considering factors such as delinquency, LTV ratio, and credit scores. The Bank evaluates the consumer portfolios throughout their life cycles on a portfolio basis. When problem loans are identified that are secured with collateral, management examines the loan files to evaluate the nature and type of collateral supporting the loans. Management documents the collateral type, the date of the most recent valuation, and whether any liens exist, to determine the value to compare against the committed loan amount. Within the consumer loan portfolio segment, for both residential and home equity loans, loss severity assumptions are incorporated into the loan and lease loss reserve models to estimate loan balances that will ultimately charge off. These assumptions are based on recent loss experience for six LTV bands within the portfolios. LTV ratios are updated based on movements in the state-level Federal Housing Finance Agency house pricing indices. For non-TDR RICs and personal unsecured loans, the Company estimates the ALLL at a level considered adequate to cover probable credit losses in the recorded investment of the portfolio. Probable losses are estimated based on contractual delinquency status and historical loss experience, in addition to the Company’s judgment of estimates of the value of the underlying collateral, bankruptcy trends, economic conditions such as unemployment rates, changes in the used vehicle value index, delinquency status, historical collection rates and other information in order to make the necessary judgments as to probable loan and lease losses. In addition to the ALLL, management estimates probable losses related to unfunded lending commitments. Unfunded lending commitments for commercial customers are analyzed and segregated by risk according to the Company's internal risk rating scale. These risk classifications, in conjunction with an analysis of historical loss experience, current economic conditions, performance trends within specific portfolio segments, and any other pertinent information result in the estimation of the reserve for unfunded lending commitments. Additions to the reserve for unfunded lending commitments are made by charges to the provision for credit losses, and this reserve is classified within Other liabilities on the Company's Consolidated Balance Sheets. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Risk factors are continuously reviewed and revised by management when conditions warrant. A comprehensive analysis of the ACL is performed by the Company on a quarterly basis. In addition, a review of allowance levels based on nationally published statistics is conducted on at least an annual basis. The ACL is subject to review by banking regulators. The Company's primary bank regulators conduct examinations of the ACL and make assessments regarding its adequacy and the methodology employed in its determination.
Interest Recognition and Non-accrual Loans	Interest Recognition and Non-accrual loans Interest from loans is accrued when earned in accordance with the terms of the loan agreement. The accrual of interest is discontinued and uncollected interest is reversed once a loan is placed in non-accrual status. A loan is determined to be non-accrual when it is probable that scheduled payments of principal and interest will not be received when due according to the contractual terms of the loan agreement. The Company generally places commercial loans and consumer loans on non-accrual status when they become 90 days or more past due. Additionally, loans may be placed on nonaccrual status based on other circumstances, such as receipt of notification of a customer’s bankruptcy filing. When the collectability of the recorded loan balance of a nonaccrual loan is in doubt, any cash payments received from the borrower are applied first to reduce the carrying value of the loan. Otherwise, interest income may be recognized to the extent cash is received. Generally, a nonaccrual loan is returned to accrual status when, based on the Company’s judgment, the borrower’s ability to make the required principal and interest payments has resumed and collectability of remaining principal and interest is no longer doubtful. Interest income recognition resumes for nonaccrual loans that were accounted for on a cash basis method when they return to accrual status, while interest income that was previously recorded as a reduction in the carrying value of the loan would be recognized as interest income based on the effective yield to maturity on the loan. Collateral- dependent loans are generally not returned to accrual status. Please refer to the TDRs section below for discussion related to TDR loans placed on non-accrual status. Credit cards continue to accrue interest until they become 180 days past due, at which point they are charged-off. For RICs, the accrual of interest is discontinued and accrued, but uncollected interest is reversed once a RIC becomes more than 60 days past due (i.e. 61 or more days past due), and is resumed if a delinquent account subsequently becomes 60 days or less past due. The Company considers an account delinquent when an obligor fails to pay substantially all (defined as 90% ) of the scheduled payment by the due date. The payment following the partial payment must be a full payment, or the account will move into delinquency status at that time. Loans accounted for using the FVO are not placed on nonaccrual. Charge-off of Uncollectible Loans Any loan may be charged-off if a loss confirming event has occurred. Loss confirming events usually involve the receipt of specific adverse information about the borrower and may include bankruptcy (unsecured), foreclosure, or receipt of an asset valuation indicating a shortfall between the value of the collateral and the book value of the loan when that collateral asset is the sole source of repayment. The Company generally charges off commercial loans when it is determined that the specific loan or a portion thereof is uncollectible. This determination is based on facts and circumstances of the individual loans and normally includes considering the viability of the related business, the value of any collateral, the ability and willingness of any guarantors to perform and the overall financial condition of the borrower. Partially charged-off loans continue to be evaluated on not less than a quarterly basis, with additional charge-offs or loan and lease loss provisions taken on the remaining loan balance, if warranted, utilizing the same criteria. The Company generally charges off consumer loans, or a portion thereof, as follows: residential mortgage loans and home equity loans are charged-off to the estimated fair value of their collateral (net of selling costs) when they become 180 days past due, and other loans (closed-end) are charged-off when they become 120 days past due. Loans with respect to which a bankruptcy notice is received or for which fraud is discovered are written down to the collateral value less costs to sell within 60 days of such notice or discovery. Revolving personal unsecured loans are charged off when they become 180 days past due. Credit cards are charged off when they are 180 days delinquent or within 60 days after the receipt of notification of the cardholder’s death or bankruptcy. Charge-offs are not required when it can be clearly demonstrated that repayment will occur regardless of delinquency status. Factors that would demonstrate repayment include a loan that is secured by collateral and is in the process of collection, a loan supported by a valid guarantee or insurance, or a loan supported by a valid claim against a solvent estate. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) RICs and auto loans are charged off against the allowance in the month in which the account becomes 120 days contractually delinquent if the Company has not repossessed the related vehicle. The Company charges off accounts in repossession when the automobile is repossessed and legally available for disposition. A net charge off represents the difference between the estimated net sales proceeds and the Company's recorded investment in the related contract. Accounts in repossession that have been charged off and are pending liquidation are removed from loans and the related repossessed automobiles are included in Other assets in the Company's Consolidated Balance Sheets. TDRs TDRs are loans that have been modified for which the Company has agreed to make certain concessions to customers to both meet the needs of the customers and maximize the ultimate recovery of the loan. TDRs occur when a borrower is experiencing financial difficulties and the loan is modified to provide a concession that would otherwise not be granted to the borrower. The types of concessions granted are generally interest rate reductions, limitations on accrued interest charged, term extensions, and deferments of principal. TDRs are generally placed on non-accrual status at the time of modification, unless the loan was performing immediately prior to modification and returned to accrual after a sustained period of repayment performance. Collateral dependent TDRs are generally not returned to accrual status. All costs incurred by the Company in connection with a TDR are expensed as incurred. The TDR classification remains on the loan until it is paid in full or liquidated. Commercial Loan TDRs All of the Company’s commercial loan modifications are based on the circumstances of the individual customer, including specific customers' complete relationship with the Company. Loan terms are modified to meet each borrower’s specific circumstances at a point in time and may allow for modifications such as term extensions and interest rate reductions. Commercial loan TDRs are generally restructured to allow for an upgraded risk rating and return to accrual status after a sustained period of payment performance has been achieved (typically 12 months for monthly payment schedules). As TDRs, they will be 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. Consumer Loan TDRs The majority of the Company's TDR balance is comprised of RICs and auto loans. The terms of the modifications for the RIC and auto loan portfolio generally include one or a combination of: a reduction of the stated interest rate of the loan at a rate of interest lower than the current market rate for new debt with similar risk or an extension of the maturity date. In accordance with our policies and guidelines, the Company at times offers extensions (deferrals) to consumers on our RICs under which the consumer is allowed to defer a maximum of three payments per event to the end of the loan. More than 90% of deferrals granted are for two payments. Our policies and guidelines limit the frequency of each new deferral that may be granted to one deferral every six months , regardless of the length of any prior deferral. The maximum number of months extended for the life of the loan for all automobile RICs is eight , while some marine and RV contracts have a maximum of twelve months extended to reflect their longer term. Additionally, we generally limit the granting of deferrals on new accounts until a requisite number of payments has been received. During the deferral period, we continue to accrue and collect interest on the loan in accordance with the terms of the deferral agreement. The Company considers all individually acquired RICs that have been modified at least once, deferred for a period of 90 days or more, or deferred at least twice, as TDRs. Additionally, restructurings through bankruptcy proceedings are deemed to be TDRs. RIC TDRs are placed on non-accrual status when the Company believes repayment under the revised terms is not reasonably assured and, at the latest, when the account becomes past due more than 60 days . For loans on nonaccrual status, interest income is recognized on a cash basis. For TDR loans on nonaccrual status, the accrual of interest is resumed if a delinquent account subsequently becomes 60 days or less past due. At the time a deferral is granted on a RIC, all delinquent amounts may be deferred or paid, resulting in the classification of the loan as current and therefore not considered a delinquent account. Thereafter, the account is aged based on the timely payment of future installments in the same manner as any other account. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Changes in deferral levels do not have a direct impact on the ultimate amount of consumer finance receivables charged off. However, the timing of a charge-off may be affected if the previously deferred account ultimately results in a charge-off. To the extent that deferrals impact the ultimate timing of when an account is charged off, historical charge-off ratios, loss confirmation periods, and cash flow forecasts for loans classified as TDRs used in the determination of the adequacy of the ALLL are also impacted. Increased use of deferrals may result in a lengthening of the loss confirmation period, which would increase expectations of credit losses inherent in the portfolio and therefore increase the ALLL and related provision for loan and lease losses. Changes in these ratios and periods are considered in determining the appropriate level of ALLL and related provision for loan and lease losses. 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. Consumer TDRs in the residential mortgage and home equity portfolios are generally placed on non-accrual status at the time of modification, and returned to accrual when they have made six consecutive on-time payments. In addition to those identified as TDRs above, loans discharged under Chapter 7 bankruptcy are considered TDRs and collateral-dependent, regardless of delinquency status. These loans are written down to fair market value and classified as non-accrual/non-performing for the remaining life of the loan. TDR Impact to ALLL The ALLL is established to recognize losses in funded loans 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 using the effective interest rate or fair value of collateral (less costs to sell). The amount of the required valuation allowance 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 subsequently defaulted loans 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 the fair values of their collateral less its estimated cost to sell. Accordingly, upon TDR modification or if a TDR modification subsequently defaults, the allowance methodology remains unchanged. Impaired loans A loan is considered to be impaired when, based upon current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan. An insignificant delay (e.g., less than 61 days for RICs or less than 90 days for all of the Company's other loans) or insignificant shortfall in amount of payments does not necessarily result in the loan being identified as impaired. The Company considers all of its TDRs and all of its non-accrual commercial loans in excess of $1 million to be impaired as of the balance sheet date. The Company may perform an impairment analysis on loans that fail to meet this threshold if the nature of the collateral or business conditions warrant. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) The Company measures impairment on impaired loans based on the present value of expected future cash flows discounted at the loan's original effective interest rate, except that, as a practical expedient, the Company may measure impairment based on a loan's observable market price, or the fair value of the collateral, less the costs to sell, if the loan is a collateral-dependent loan. Some impaired loans share common risk characteristics. Such loans are collectively assessed for impairment and the Company utilizes historical loan loss experience information as part of its evaluation. When the Company determines that the present value of the estimated cash flows of an impaired loan is less than its carrying amount, the Company recognizes impairment through a provision estimate or a charge-off to the allowance. Management performs these assessments on at least a quarterly
LHFS	LHFS LHFS are recorded at either estimated fair value (if the FVO is elected) or the lower of cost or fair value. The Company has elected to account for most of its residential real estate mortgages originated with the intent to sell at fair value. Generally, residential loans are valued on an aggregate portfolio basis, and commercial loans are valued on an individual loan basis. Gains and losses on LHFS which are accounted for at fair value are recorded in Miscellaneous income, net. For residential mortgages for which the FVO is selected, direct loan origination fees are recorded in Miscellaneous income, net at origination. All other LHFS which the Company does not have the intent and ability to hold for the foreseeable future or until maturity or payoff are carried at the lower of cost or fair value. When loans are transferred from HFI, the Company will recognize a charge-off to the ALLL, if warranted under the Company’s charge off policies. Any excess ALLL for the transferred loans is reversed through provision expense. Subsequent to the initial measurement of LHFS, market declines in the recorded investment, whether due to credit or market risk, are recorded through miscellaneous income, net as lower of cost or market adjustments.
Leases	Leases (as Lessor) The Company provides financing for various types of equipment, aircraft, energy and power systems, and automobiles through a variety of lease arrangements. The Company’s investments in leases that are accounted for as direct financing leases are carried at the aggregate of lease payments plus estimated residual value of the leased property less unearned income, and are reported as part of LHFI in the Company’s Consolidated Balance Sheets. Leveraged leases, a form of financing lease, are carried net of non-recourse debt. The Company recognizes income over the term of the lease using the effective interest method, which provides a constant periodic rate of return on the outstanding investment on the lease. Leased vehicles under operating leases are carried at amortized cost net of accumulated depreciation and any impairment charges and presented as Operating lease assets, net in the Company’s Consolidated Balance Sheets. Leased assets acquired in a business combination are initially recorded at their estimated fair value. Leased vehicles purchased in connection with newly originated operating leases are recorded at amortized cost. The depreciation expense of the vehicles is recognized on a straight-line basis over the contractual term of the leases to the expected residual value. The expected residual value and, accordingly, the monthly depreciation expense may change throughout the term of the lease. The Company estimates expected residual values using independent data sources and internal statistical models that take into consideration economic conditions, current auction results, the Company’s remarketing abilities, and manufacturer vehicle and marketing programs. Lease payments due from customers are recorded as income within Lease income in the Company’s Consolidated Statements of Operations, unless and until a customer becomes more than 60 days delinquent, at which time the accrual of revenue is discontinued. The accrual is resumed if a delinquent account subsequently becomes 60 days or less past due. Payments from the vehicle’s manufacturer under its subvention programs are recorded as reductions to the cost of the vehicle and are recognized as an adjustment to depreciation expense on a straight-line basis over the contractual term of the lease. The Company periodically evaluates its investment in operating leases for impairment if circumstances such as a systemic and material decline in used vehicle values occurs. This would include, for example, a decline in the residual value of our lease portfolio due to an event caused by shocks to oil and gas prices that have a pronounced impact on certain models of vehicles, pervasive manufacturer defects, or other events that could systemically affect the value of a particular brand or model of leased asset, which indicates that impairment may exist. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Under the accounting for impairment or disposal of long-lived assets, residual values of leased assets under operating leases are evaluated individually for impairment. When aggregate future cash flows from the operating lease, including the expected realizable fair value of the leased asset at the end of the lease, are less than the book value of the lease, an immediate impairment write-down is recognized if the difference is deemed not recoverable. Otherwise, reductions in the expected residual value result in additional depreciation of the leased asset over the remaining term of the lease. Upon disposition, a gain or loss is recorded for any difference between the net book value of the leased asset and the proceeds from the disposition of the asset, including any insurance proceeds. Gains or losses on the sale of leased assets are included in Miscellaneous income, net, while valuation adjustments on operating lease residuals are included in Other administrative expense in the Consolidated Statements of Operations. No impairment for leased assets was recognized during the years ended December 31, 2019 , 2018 , or 2017 . Leases (as Lessee) Operating lease ROU assets and lease liabilities are recognized upon lease commencement based on the present value of lease payments over the lease term, discounted at the Company's estimated rate of interest for a collateralized borrowing for a similar term. The lease term includes options to extend or terminate a lease when the Company considers it reasonably certain that such options will be exercised. Lease expense for operating leases is recognized on a straight-line basis over the lease term.
Premises and Equipment	Premises and Equipment Premises and equipment are carried at cost, less accumulated depreciation. Depreciation is calculated utilizing the straight-line method. Estimated useful lives are as follows: Office buildings 10 to 50 years Leasehold improvements (1) 10 to 30 years Software (2) 3 to 7 years Furniture, fixtures and equipment 3 to 10 years Automobiles 5 years (1) Leasehold improvements are depreciated over the shorter of the useful lives of the assets or the remaining term of the leases. (2) The standard depreciable period for software is three years . However, for certain software implementation projects, a seven -year period is utilized.
Equity Method Investments	Equity Method Investments The Company uses the equity method for general and limited partnership interests, limited liability companies and other unconsolidated equity investments in which the Company is considered to have significant influence over the operations of the investee. Under the equity method, the Company records its equity ownership share of net income or loss of the investee in "Other miscellaneous expenses." Investments accounted for under the equity method of accounting above are included in the caption "Other Assets" on the Consolidated Balance Sheets.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is the excess of the purchase price over the fair value of the tangible and identifiable intangible assets and liabilities of companies acquired through business combinations accounted for under the acquisition method. Goodwill and other indefinite-lived intangible assets are not amortized on a recurring basis, but rather are subject to periodic impairment testing. The Company conducts its evaluation of goodwill impairment at the reporting unit level on an annual basis at October 1, and more frequently if events or circumstances indicate that the carrying value of a reporting unit exceeds its fair value. A reporting unit is an operating segment or one level below. An entity's goodwill impairment quantitative analysis is required to be completed unless the entity determines, based on certain qualitative factors, that it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is greater than its carrying amount, including goodwill, in which case no further analysis is required. An entity has an unconditional option to bypass the preceding qualitative assessment (often referred to as step 0) for any reporting unit in any period and proceed directly to the quantitative goodwill impairment test. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) The quantitative test includes a comparison of the fair value of each reporting unit to its respective carrying amount, including its allocated goodwill. If the fair value of the reporting unit is in excess of the carrying value, the related goodwill is considered not to be impaired and no further analysis is necessary. If the carrying value of the reporting unit is higher than the fair value, the impairment is measured as the excess of carrying value over fair value. A recognized impairment charge cannot exceed the amount of goodwill allocated to a reporting unit and cannot subsequently be reversed even if the fair value of the reporting unit recovers. The Company's intangible assets consist of assets purchased or acquired through business combinations, including trade names and dealer networks. Certain intangible assets are amortized over their useful lives. The Company evaluates identifiable intangibles for impairment when an indicator of impairment exists, but not less than annually. Separable intangible assets that are not deemed to have an indefinite life continue to be amortized over their useful lives.
MSRs	MSRs The Company has elected to measure most of its residential MSRs at fair value to be consistent with the risk management strategy to hedge changes in the fair value of these assets. The fair value of residential MSRs is estimated by using a cash flow valuation model which calculates the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, servicing costs, and other economic factors which are determined based on current market conditions. Assumptions incorporated into the residential MSRs valuation model reflect management's best estimate of factors that a market participant would use in valuing the residential MSRs. Although sales of residential MSRs do occur, residential MSRs do not trade in an active market with readily observable prices. Those MSRs not accounted for at fair value are accounted for at amortized cost, less impairment. As a benchmark for the reasonableness of the residential MSRs' fair value, opinions of value from independent third parties ("Brokers") are obtained. Brokers provide a range of values based upon their own discounted cash flow DCF calculations of our portfolio that reflect conditions in the secondary market and any recently executed servicing transactions. Management compares the internally-developed residential MSR values to the ranges of values received from Brokers. If the residential MSRs fair value falls outside the Brokers' ranges, management will assess whether a valuation adjustment is warranted. Residential MSRs value is considered to represent a reasonable estimate of fair value.
BOLI	BOLI BOLI represents the cash surrender value of life insurance policies for certain current and former employees who have provided positive consent to allow the Bank to be the beneficiary of such policies. Increases in the net cash surrender value of the policies, as well as insurance proceeds received, are recorded in non-interest income, and are not subject to income taxes.
OREO and Other Repossessed Assets	OREO and Other Repossessed Assets OREO and other repossessed assets consist of properties, vehicles, and other assets acquired by, or in lieu of, foreclosure or repossession in partial or total satisfaction of NPLs, including RICs and leases. Assets obtained in satisfaction of a loan are recorded at the estimated fair value minus estimated costs to sell based upon the asset's appraisal value at the date of transfer. The excess of the carrying value of the loan over the fair value of the asset minus estimated costs to sell are charged to the ALLL at the initial measurement date. Subsequent to the acquisition date, OREO and repossessed assets are carried at the lower of cost or estimated fair value, net of estimated cost to sell. Any declines in the fair value of OREO and repossessed assets below the initial cost basis are recorded through a valuation allowance with a charge to non-interest income. Increases in the fair value of OREO and repossessed assets net of estimated selling costs will reverse the valuation allowance, but only up to the cost basis which was established at the initial measurement date. Costs of holding the assets are recorded as operating expenses, except for significant property improvements, which are capitalized to the extent that the carrying value does not exceed the estimated fair value. The Company generally begins vehicle repossession activity once a customer's account becomes 60 days past due. The customer has an opportunity to redeem the repossessed vehicle by paying all outstanding balances, including finance changes and fees. Any vehicles not redeemed are sold at auction. OREO and other repossessed assets are recorded within Other assets on the Consolidated Balance Sheets.
Derivatives Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company uses derivative financial instruments primarily to help manage exposure to interest rate, foreign exchange, equity, and credit risk. Derivative financial instruments are also used to reduce the effects that changes in interest rates may have on net income, the fair value of assets and liabilities, and cash flows. The Company also enters into derivatives with customers to facilitate their risk management activities, and often sells derivative products to commercial loan customers to hedge interest rate risk associated with loans made by the Company. The Company uses derivative financial instruments as risk management tools and not for speculative trading purposes for its own account. Derivative financial instruments are recognized as either assets or liabilities in the consolidated balance sheets at fair value. The accounting for changes in the fair value of each derivative financial instrument depends on whether it has been designated and qualifies as a hedge for accounting purposes, as well as the type of hedging relationship identified. Derivative instruments designated in a hedge relationship to mitigate exposure to changes in the fair value of an asset, liability or firm commitment attributable to a particular risk such as interest rate risk are considered fair value hedges. Derivative instruments designated in a hedge relationship to mitigate exposure to variability in expected future cash flows or other types of forecasted transactions are considered cash flow hedges. The Company formally documents the relationships of qualifying hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking each hedge transaction. Fair value hedges that are highly effective are accounted for by recording the change in the fair value of the derivative instrument and the related hedged asset, liability or firm commitment on the Consolidated Balance Sheets, with the corresponding income or expense recorded in the Consolidated Statements of Operations. The adjustment to the hedged asset or liability is included in the basis of the hedged item, while the fair value of the derivative is recorded as an other asset or other liability. Actual cash receipts or payments and related amounts accrued during the period on derivatives included in a fair value hedge relationship are recorded as adjustments to the income or expense associated with the hedged asset or liability. Cash flow hedges that are highly effective are accounted for by recording the fair value of the derivative instrument on the Consolidated Balance Sheets as an asset or liability, with a corresponding charge or credit for the change in the fair value of the derivative, net of tax, recorded in accumulated OCI within stockholder's equity in the accompanying Consolidated Balance Sheets. Amounts are reclassified from accumulated OCI to the Consolidated Statements of Operations in the period or periods the hedged transaction affects earnings. In the case in which certain cash flow hedging relationships have been terminated, the Company continues to defer the net gain or loss in accumulated OCI and reclassifies it into interest expense as the future cash flows occur, unless it becomes probable that the future cash flows will not occur. We discontinue hedge accounting when it is determined that the derivative no longer qualifies as an effective hedge; the derivative expires or is sold, terminated or exercised; the derivative is de-designated as a fair value or cash flow hedge; or, for a cash flow hedge, it is no longer probable that the forecasted transaction will occur by the end of the originally specified time period. If we determine that the derivative no longer qualifies as a fair value or cash flow hedge and hedge accounting is discontinued, the derivative will continue to be recorded on the balance sheet at its fair value, with changes in fair value included in current earnings. For a discontinued fair value hedge, the previously hedged item is no longer adjusted for changes in fair value. Changes in the fair value of derivatives not designated in hedging relationships are recognized immediately in the Consolidated Statements of Operations. Derivatives are classified in the Consolidated Balance Sheets as "Other assets" or "Other liabilities," as applicable.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method. Deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. On December 22, 2017, the TCJA was enacted. Effective January 1, 2018, the TCJA, among other things, reduced the federal corporate income tax rate from 35% to 21%. Deferred tax assets and liabilities are measured using enacted tax rates that will apply to taxable income in the years in which those temporary differences are expected to reverse or be realized. The effect of a change in tax rates on deferred tax assets and liabilities is recognized as income or expense in the period that includes the enactment date. A valuation allowance will be established if the Company determines that it is more likely than not that a deferred tax asset will not be realized. This requires periodic analysis of the carrying amount of deferred tax assets and when the deferred tax assets will be realized in future periods. Consideration is given to all positive and negative evidence related to the realization of deferred tax assets. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) In establishing a provision for income tax expense, the Company must make judgments and interpretations about the application of inherently complex tax laws of the U.S., its states and municipalities, and abroad. 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. Interest and penalties on income tax payments are included within Income tax provision on the Consolidated Statements of Operations. The Company recognizes tax benefits in its financial statements when it is more likely than not the related tax position will be sustained upon examination by tax authorities. Such tax positions are initially and subsequently measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the taxing authority, assuming full knowledge of the position and all relevant facts. See Note 15 to the Consolidated Financial Statements for details on the Company's income taxes.
Stock-Based Compensation	Stock-Based Compensation The Company, through Santander, sponsors stock plans under which incentive and non-qualified stock options and non-vested stock may be granted periodically to certain employees. The Company recognizes compensation expense related to stock options and non-vested stock awards based upon the fair value of the awards on the date of the grant, which is charged to earnings over the requisite service period (i.e., the vesting period). The impact of the forfeiture of awards is recognized as forfeitures occur. Amounts in the Consolidated Statements of Operations associated with the Company's stock compensation plan were negligible in all years presented.
Guarantees	Guarantees Certain off-balance sheet financial instruments of the Company meet the definition of a guarantee that require the Company to perform and make future payments in the event specified triggering events or conditions were to occur over the term of the guarantee. In accordance with the applicable accounting rules, it is the Company’s accounting policy to recognize a liability at inception associated with such a guarantee at the greater of the fair value of the guarantee or the Company's estimate of the contingent liability arising from the guarantee. Subsequent to initial recognition, the liability is adjusted based on the passage of time to perform under the guarantee and the changes to the probabilities of occurrence related to the specified triggering events or conditions that would require the Company to perform on the guarantee.
Business Combinations	Business Combinations The Company accounts for business combinations using the acquisition method of accounting, and records the identifiable assets, liabilities and any NCI of the acquired business at their acquisition date fair values. The excess of the purchase price over the estimated fair value of the net assets acquired is recorded as goodwill. Any changes in the estimated acquisition date fair values of the net assets recorded prior to the finalization of a more detailed analysis, but not to exceed one year from the date of acquisition, will change the amount of the purchase price allocable to goodwill. Any subsequent changes to any purchase price allocations that are material to the Company’s Consolidated Financial Statements will be adjusted retrospectively. All acquisition related costs are expensed as incurred. The results of operations of the acquired companies are recorded in the Consolidated Statements of Operations from the date of acquisition. The application of business combination principles, including the determination of the fair value of the net assets acquired, requires the use of significant estimates and assumptions.
Revenues	Revenue Recognition The Company primarily earns interest and non-interest income from various sources, including: • Lending (interest income and loan fees) • Investment securities • Loan sales and servicing • Finance leases • BOLI • Depository services • Commissions and trailer fees • Interchange income, net. • Underwriting service Fees • Asset and wealth management fees NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Lending and Investment Securities The principal source of revenue is interest income from loans and investment securities. Interest income is recognized on an accrual basis primarily according to non-discretionary formulas in written contracts, such as loan agreements or securities contracts. Revenue earned on interest-earning assets, including amortization of deferred loan fees and origination costs and the accretion of discounts recognized on acquired or purchased loans, is recognized based on the constant effective yield of such interest-earning assets. Gains or losses on sales of investment securities are recognized on the trade date. Loan Sales and Servicing The Company recognizes revenue from servicing commercial mortgages and consumer loans as earned. Mortgage banking income, net includes fees associated with servicing loans for third parties based on the specific contractual terms and changes in the fair value of MSRs. Gains or losses on sales of residential mortgage, multifamily and home equity loans are included within mortgage banking revenues and are recognized when the sale is complete. Finance Leases Income from finance leases is recognized as part of interest income over the term of the lease using the constant effective yield method, while income arising from operating leases is recognized as part of other non-interest income over the term of the lease on a straight-line basis. BOLI Income from BOLI represents increases in the cash surrender value of the policies, as well as insurance proceeds and interest. Depository services Depository services are performed under an agreement with a customer, and those services include personal deposit account opening and maintenance, checking services, online banking services, debit card services, etc. Depository service fees related to customer deposits can generally be distinguished between monthly service fees and transactional fees within the single performance obligation of providing depository account services. Monthly account service and maintenance fees are provided over a period of time (usually a month), and revenue is recognized as the Company performs the service (usually at the end of the month). The services for transactional fees are performed at a point in time and revenue is recognized when the transaction occurs. Commissions and trailer fees Commission fees are earned from the selling of annuity contracts to customers on behalf of insurance companies, acting as the broker for certain equity trading, and sales of interests in mutual funds. The Company elected the expected value method for estimating commission fees due to the large number of customer contracts with similar characteristics. However, commissions and trailer fees are fully constrained as the Company cannot sufficiently estimate the consideration which it could be entitled to earn. Commissions are generally associated with point-in-time transactions or agreements that are one year or less. The performance obligation is satisfied immediately and revenue is recognized as the Company performs the service. Interchange income, net The Company has entered into agreements with payment networks under which the Company will issue the payment network's credit card as part of the Company's credit card portfolio. Each time a cardholder makes a purchase at a merchant and the transaction is processed, the Company receives an interchange fee in exchange for the authorization and settlement services provided to the payment networks. The performance obligation for the Company is to provide authorization and settlement services to the payment network when the payment network submits a transaction for authorization. The Company considers the payment network to be the customer, and the Company is acting as a principal when performing the transaction authorization and settlement services. The performance obligation for authorization and settlement services is satisfied at a point in time, and revenue is recognized on the date when the Company authorizes and routes the payment to the merchant. The expenses paid to payment networks are accounted for as consideration payable to the customer and therefore reduce the transaction price. Therefore, interchange income is recorded net against the expenses paid to the payment network and the cost of rewards programs. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) The agreements also contain immaterial fixed consideration related to upfront sign-on bonuses and program development bonuses, which are amortized over the remainder of the agreements' life on a straight-line basis. Underwriting service fees SIS, as a registered broker-dealer, performs underwriting services by raising investment capital from investors on behalf of corporations that are issuing securities. Underwriting services have one performance obligation, which is satisfied on the day SIS purchases the securities. Underwriting services include multiple parties in delivering the performance obligation. The Company has evaluated whether it is the principal or agent when we provide underwriting services. The Company acts as the principal when performing underwriting services, and recognizes fees on a gross basis. Revenue is recorded as the difference between the price the Company pays the issuer of the securities and the public offering price, and expenses are recorded as the proportionate share of the underwriting costs incurred by SIS. The Company is the principal because we obtain control of the services provided by third-party vendors and combine them with other services as part of delivering on the underwriting service. Asset and wealth management fees Asset and wealth management fees includes fee income generated from discretionary investment management and non-discretionary investment advisory contracts with customers. Discretionary investment management fees are earned for the management of the assets in the customer's account and are recognized as earned and charged to the customer on a quarterly basis. Non-discretionary investment advisory fees are earned for providing investment advisory services to customers, such as recommending the re-balancing or restructuring of the assets in the customer’s account. The investment advisory fee is recognized as earned and charged to the customer on a quarterly basis. The fee for the discretionary and nondiscretionary contracts is based on a percentage of the average assets included in the customer’s account.
Fair Value Measurements	Fair Value Measurements The Company uses fair value measurements to estimate the fair value of certain assets and liabilities for both measurement and disclosure purposes. 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, 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. When measuring the fair value of a liability, the Company assumes that the transfer will not affect the nonperformance risk associated with the liability. The Company considers the effect of the credit risk on the fair value for any period in which fair value is measured. There are three valuation approaches for measuring fair value: the market approach, the income approach and the cost approach. Selecting the appropriate technique for valuing a particular asset or liability should consider the exit market for the asset or liability, the nature of the asset or liability being measured, and how a market participant would value the same asset or liability. Ultimately, selecting the appropriate valuation method requires significant judgment. These assumptions result in classification of financial instruments into the fair value hierarchy levels 1, 2 and 3 for disclosure purposes. Valuation inputs refer to the assumptions market participants would use in pricing a given asset or liability. Inputs can be observable or unobservable. Observable inputs are assumptions based on market data obtained from an independent source. Unobservable inputs are assumptions based on the Company's own information or assessment of assumptions used by other market participants in pricing the asset or liability. The unobservable inputs are based on the best and most current information available on the measurement date. General A portion of the Company’s assets and liabilities are carried at fair value, including investments in debt securities AFS 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 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. 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 Company'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. NOTE 16. FAIR VALUE (continued) 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.
