Accounting Policies [Abstract]
DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION AND ACCOUNTING POLICIES	DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION AND ACCOUNTING POLICIES SHUSA is the parent holding company of SBNA, a national banking association; SC, a consumer finance company headquartered in Dallas, Texas; 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; 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; SFS, a consumer credit institution headquartered in Puerto Rico; and several other subsidiaries. SHUSA is headquartered in Boston and SBNA's home office is in Wilmington, Delaware. SSLLC and SIS are registered investment advisers with the SEC. SHUSA's two largest subsidiaries by asset size and revenue are SBNA and SC. SHUSA is a wholly-owned subsidiary of Santander. As of September 30, 2021, SC was owned approximately 80.2% by SHUSA and 19.8% by other shareholders. SC Common Stock is listed on the NYSE under the trading symbol "SC." Correction of Errors Subsequent to the issuance of the Company's September 30, 2021 , Consolidated Financial Statements, errors were in the historical Consolidated Statement of Cash Flows for the nine-month period ended September 30, 2021 . Accordingly, the Company has restated the unaudited interim Condensed Consolidated Statement of Cash Flows for the nine-month period ended September 30, 2021 , to reflect the error corrections. The errors originate from SC, a significant subsidiary of the Company. • During the nine-month period ended September 30, 2021 , the Company reported $1,171 million of Originations of LHFS within Net Cash Provided by Operating Activities that should have been reported as Net change in loans other than purchases and sales within Net Cash Provided by Investing Activities. • During the nine-month period ended September 30, 2021 , the Company reported $404 million as Proceeds from sales of and collections on LHFS within Net Cash Provided by Operating Activities that should have been reported as Net change in loans other than purchases and sales within Net Cash Provided by Investing Activities. The impact of the above two errors on the Company’s Consolidated Statement of Cash Flows for the nine-month period ended September 30, 2021 is as follows: Nine-Month Period Ended September 30, 2021 (in thousands) As Reported (1) Corrections As Restated Originations of LHFS $ (2,283,675) $ 1,171,287 $ (1,112,388) Proceeds from sales of and collections on LHFS 2,935,656 (403,631) 2,532,025 NET CASH PROVIDED BY OPERATING ACTIVITIES $ 5,961,580 $ 767,656 $ 6,729,236 Net change in loans other than purchases and sales $ (578,897) $ (767,656) $ (1,346,553) NET CASH USED IN INVESTING ACTIVITIES $ (2,692,526) $ (767,656) $ (3,460,182) (1) Originally reported amounts included in the Quarterly Report on Form 10-Q for the nine-month period ended September 30, 2021 filed on November 2, 2021.

Intangible assets will be amortized over t he estimated useful life of six years. NOTE 1. DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Agreement to Acquire Pierpont Capital Holdings LLC In July 2021, SHUSA announced that it has reached an agreement to acquire PCH, parent company of Amherst Pierpont Securities, a market-leading independent fixed-income broker dealer, for a total consideration of approximately $450 million.

The transaction is expected to close subject to regulatory approvals and customary closing conditions. Proposal to Acquire SC Shares In August 2021, SHUSA entered into a definitive agreement whereby SHUSA agreed to acquire all of the outstanding shares of SC Common Stock not already owned by SHUSA via an all-cash tender offer. Under the terms of the definitive agreement, a wholly-owned subsidiary of SHUSA commenced a tender offer to acquire all outstanding shares of SC Common Stock that SHUSA does not already own at a price of $41.50 per share in cash. SHUSA agreed to acquire all remaining shares not tendered in the tender offer through a second-step merger at the same price as in the tender offer. Consummation of the tender offer is subject to various conditions, including regulatory approval by the Federal Reserve and other customary closing conditions. Upon completion of the transaction, SC will become a wholly-owned subsidiary of SHUSA. Core Business SBNA’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, principally located in Massachusetts, New Hampshire, Connecticut, Rhode Island, New York, New Jersey, Pennsylvania, and Delaware. SBNA uses its deposits, as well as other financing sources, to fund its loan and investment portfolios. NOTE 1. DESCRIPTION OF BUSINESS, BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) SC is a specialized consumer finance company focused on vehicle finance and third-party servicing and delivering service to dealers and customers across the full credit spectrum. SC's primary business is the indirect origination and servicing of RICs and auto 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 financing brand, and is available as a finance option for automotive dealers across the United States. Since May 2013, under the MPLFA with Stellantis, SC has operated as Stellantis's preferred provider for consumer loans, leases, and dealer loans and provides services to Stellantis customers and dealers under the CCAP 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. In 2019, SC entered into an amendment to the MPLFA 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. Basis of Presentation These Condensed Consolidated Financial Statements include the accounts of the Company and its consolidated subsidiaries, including certain 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 Condensed Consolidated Financial Statements have been prepared in accordance with GAAP and pursuant to SEC regulations. In the opinion of management, the accompanying Condensed Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary for a fair statement of the Consolidated Balance Sheets, Statements of Operations, Statements of Comprehensive Income, Statements of Stockholder's Equity and Statement of Cash Flow for the periods indicated, and contain adequate disclosure to make the information presented not misleading. Results of operations for the periods presented herein are not necessarily indicative of results of operations for the entire year. These financial statements should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2020. 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 consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates, and those differences may be material. The most significant estimates include the ACL, fair value measurements, expected end-of-term lease residual values, goodwill, and income taxes. These estimates, although based on actual historical trends and modeling, may potentially show significant variances over time. Accounting Policies There have been no changes in the Company's accounting policies from those disclosed in the 2020 Annual Report on Form 10-K. Subsequent Events The Company evaluated events from the date of these Condensed Consolidated Financial Statements on September 30, 2021 through the issuance of these Condensed Consolidated Financial Statements, and has determined that there have been no material events that would require recognition in its Condensed Consolidated Financial Statements or disclosure in the Notes to the Condensed Consolidated Financial Statements as of September 30, 2021.

For securities that do not qualify for the zero credit loss expectation exception, management has concluded that the unrealized losses are not credit-related since (1) they are not related to the underlying credit quality of the issuers, (2) the entire contractual principal and interest due on these securities is currently expected to be recoverable, (3) the Company does not intend to sell these investments at a loss and (4) 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. 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: Three-Month Period Ended September 30, Nine-Month Period Ended September 30, (in thousands) 2021 2020 2021 2020 Proceeds from the sales of AFS securities $ — $ 1,112,033 $ 1,326,299 $ 2,665,593 Gross realized gains $ — $ 573 $ 18,267 $ 33,400 Gross realized losses (106) (721) (3,129) (1,754) Net realized gains/(losses) (1) $ (106) $ (148) $ 15,138 $ 31,646 (1) Includes net realized gain/(losses) on trading securities of $(0.1) million, and $(0.8) million for the three-month and nine-month periods ended September 30, 2021, respectively, and $(0.1) million and $(1.0) million for the three-month and nine-month periods ended September 30, 2020, respectively . The Company uses the specific identification method to determine the cost of the securities sold and the gain or loss recognized. Other Investments Other investments consisted of the following as of: (in thousands) September 30, 2021 December 31, 2020 FHLB of Pittsburgh and FRB stock $ 415,418 $ 435,330 LIHTC investments 338,292 313,603 Equity securities not held for trading (1) 14,861 14,494 Interest-bearing deposits with an affiliate bank 500,000 750,000 Trading securities 38,748 40,435 Total $ 1,307,319 $ 1,553,862 (1) Includes $2.7 million and $1.4 million of equity certificates related to an off-balance sheet securitization as of September 30, 2021 and December 31, 2020, respectively. NOTE 2. INVESTMENT SECURITIES (continued) 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 there is no market for their sale. The stocks can be sold back only at their par value of $100 per share, and FHLB stock can be sold back only to the FHLB or to another member institution. Accordingly, these stocks are carried at cost. During the three-month and nine-month periods ended September 30, 2021, the Company purchased $1.1 million and $4.5 million of FHLB stock at par, respectively, and redeemed $4.9 million and $23.8 million of FHLB stock at par. The Company redeemed zero and $0.7 million of FRB stock at par during the three-month and nine-month periods ended September 30, 2021, respectively. The Company did not purchase any FRB stock during the nine-month period ended September 30, 2021. There was no gain or loss associated with these redemptions. The Company's LIHTC investments are accounted for using the proportional amortization method. Equity securities are measured at fair value as of September 30, 2021, with changes in fair value recognized in net income, and consist primarily of CRA mutual fund investments. Interest-bearing deposits include deposits maturing in more than 90 days with Santander. With the exception of equity and trading securities, which are measured at fair value, the Company evaluates these other investments for impairment based on the ultimate recoverability of the carrying value, rather than by recognizing temporary declines in value. The Company held an immaterial amount of equity securities without readily determinable fair values at the reporting date.

(2) Loans originated during the year ended December 31, 2020. (3) Excludes LHFS. 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 CECL loss calculation incorporates the refreshed LTV information to update the distribution of defaulted loans by LTV as well as the associated LGD 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. FICO scores are refreshed quarterly, where possible. The indicators disclosed represent the credit scores for loans as of the date presented based on the most recent assessment performed. NOTE 3.

Certain LHFI are accoun ted for at fair value under the FVO. Certain loans are pledged as collateral for borrowings, securitizations, or SPEs. These loans totaled $46.4 billion at September 30, 2021 and $52.0 billion at December 31, 2020. Loans that the Company intends to sell are classified as LHFS. The LHFS portfolio balance at September 30, 2021 was $690.6 million, compared to $2.2 billion at December 31, 2020. For a discussion on the valuation of LHFS at fair value, see Note 13 to these Condensed Consolidated Financial Statements. LHFS in the residential mortgage portfolio that were originated with the intent to sell were $194.1 million as of September 30, 2021 and are reported at either estimated fair value (if the FVO is elected) or the lower of cost or fair value. Interest on loans is credited to income as it is earned. Loan origination fees and certain direct loan origination costs are deferred and recognized as adjustments to interest income in the Condensed Consolidated Statements of Operations over the contractual life of the loan utilizing the interest method. Loan origination costs and fees and premiums and discounts on RICs are deferred and recognized in interest income over their estimated lives using estimated prepayment speeds, which are updated on a monthly basis. At September 30, 2021 and December 31, 2020, accrued interest receivable on the Company's loans was $478.9 million and $589.2 million, respectively. During the nine-month periods ended September 30, 2021 and 2020, SC originated $11.1 billion and $11.1 billion, respectively, in CCAP loans (including through the SBNA originations program), which represented 53% and 61%, respectively, of the UPB of SC's total RIC originations (including the SBNA originations program). Purchased receivables During the nine months ended September 30, 2021, SBNA approved and completed purchases of performing personal unsecured loans with a UPB of approximately $641.0 million. During the three and nine months ended September 30, 2021, SC purchased financial receivables from third party lenders for $67.0 million. The UPB of these loans as of the acquisition date was $112.1 million. NOTE 3. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Sales of receivables During the first quarter of 2021, SC completed the sale of $1.3 billion in UPB of its Bluestem personal lending portfolio to a third party. In addition, SC executed a forward flow sale agreement with a third party to purchase all personal lending receivables that SC purchases from Bluestem through the term of the agreement with Bluestem. Prior to the sale, these loans were classified as LHFS. During the second quarter of 2021, SFS sold the majority of its commercial and consumer loan and REO HFS portfolios to third parties at their approximate fair values with no material gain or loss. In addition, during the second quarter of 2021, SC sold RICs with a UPB of approximately $310 million to a third party. During the nine months ended September 30, 2021 , SC sold RICs with a UPB of approximately $3.0 billion to third-parties in three separate transactions. Two of these transactions were accounted for as off-balance sheet securitizations.

LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Portfolio segments and classes The Company discloses information about the credit quality of its 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. C&I includes non-real estate-related commercial loans. "Multifamily" represents loans for multifamily residential housing units. “Other commercial” includes loans to global customer relationships in Latin America which are not defined as commercial or consumer for regulatory purposes. The remainder of the portfolio primarily represents the CEVF portfolio. The Company's portfolio classes are substantially the same as its financial statement categorization of loans for consumer loan populations. “Residential mortgages” includes mortgages on residential property, including single family and 1-4 family units. "Home equity loans and lines of credit" include all organic home equity contracts and purchased home equity portfolios. "RICs and auto loans" includes the Company's direct automobile loan portfolios, but excludes RV and marine RICs. "Personal unsecured loans" includes personal revolving loans and credit cards. “Other consumer” includes an acquired portfolio of marine RICs and RV contracts as well as indirect auto loans. ACL Rollforward by Portfolio Segment The ACL is comprised of the ALLL and the reserve for unfunded lending commitments. The activity in the ACL by portfolio segment for the three-month and nine-month periods ended September 30, 2021 and 2020 was as follows: Three-Month Period Ended September 30, 2021 (in thousands) Commercial Consumer Total ALLL, beginning of period (1) $ 641,515 $ 6,247,801 $ 6,889,316 Credit loss expense / (benefit) (37,806) 46,120 8,314 Charge-offs (28,835) (660,488) (689,323) Recoveries 15,636 491,145 506,781 Charge-offs, net of recoveries (13,199) (169,343) (182,542) ALLL, end of period $ 590,510 $ 6,124,578 $ 6,715,088 Reserve for unfunded lending commitments, beginning of period (1) $ 101,477 $ 22,807 $ 124,284 Credit loss expense / (benefit) on unfunded lending commitments 12,953 (1,774) 11,179 Reserve for unfunded lending commitments, end of period 114,430 21,033 135,463 Total ACL, end of period $ 704,940 $ 6,145,611 $ 6,850,551 Nine-Month Period Ended September 30, 2021 (in thousands) Commercial Consumer Total ALLL, beginning of period $ 752,196 $ 6,586,297 $ 7,338,493 Credit loss expense / (benefit) (107,265) (103,466) (210,731) Charge-offs (108,523) (2,049,202) (2,157,725) Recoveries 54,102 1,690,949 1,745,051 Charge-offs, net of recoveries (54,421) (358,253) (412,674) ALLL, end of period $ 590,510 $ 6,124,578 $ 6,715,088 Reserve for unfunded lending commitments, beginning of period $ 119,129 $ 27,326 $ 146,455 Credit loss expense / (benefit) on unfunded lending commitments (4,699) (6,293) (10,992) Reserve for unfunded lending commitments, end of period 114,430 21,033 135,463 Total ACL, end of period $ 704,940 $ 6,145,611 $ 6,850,551 NOTE 3.

In general, there is an inverse relationship between the credit quality of loans and projections of impairment losses so that loans with better credit quality require a lower expected loss reserve. The Company manages this risk through its underwriting, pricing strategies, credit policy standards, and servicing guidelines and practices, as well as the application of geographic and other concentration limits. NOTE 3. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) The Company estimates CECL based on prospective information as well as account-level models based on historical data. Unemployment, HPI, GDP, CRE price index and used vehicle index growth rates, along with loan level characteristics, are the key inputs used in the models for prediction of the likelihood that the borrower will default in the forecasted period (the PD). To estimate the LGD, the models use unemployment, HPI, CRE and used vehicle indices, along with loan level characteristics as key inputs. The Company has determined the reasonable and supportable period to be three years, at which time the economic forecasts generally tend to revert to historical averages. The Company utilizes qualitative factors to capture any additional risks that may not be captured in either the economic forecasts or in the historical data, including consideration of the portfolio metrics and collateral value. The Company generally uses a third-party vendor's consensus baseline macroeconomic scenario for the quantitative estimate and additional positive and negative macroeconomic scenarios to make qualitative adjustments for macroeconomic uncertainty and considers adjustments to macroeconomic inputs and outputs based on market volatility. The Company's allowance for loan losses decreased by $623.4 million from December 31, 2020, primarily due to an improved macroeconomic outlook as well as improved credit quality and performance. Non-accrual loans by Class of Financing Receivable The amortized cost basis of financial instruments that are either non-accrual with related expected credit loss or nonaccrual without related expected credit loss disaggregated by class of financing receivables and other non-performing assets is as follows: Non-accrual loans as of: (1) Non-accrual loans with no allowance (in thousands) September 30, 2021 December 31, 2020 September 30, 2021 December 31, 2020 Non-accrual loans: Commercial: CRE $ 110,376 $ 106,751 $ 89,547 $ 84,816 C&I 85,597 107,053 47,027 60,029 Multifamily 116,605 72,392 116,441 65,936 Other commercial 10,598 20,019 6,443 3,778 Total commercial loans 323,176 306,215 259,458 214,559 Consumer: Residential mortgages 98,952 160,172 39,094 98,308 Home equity loans and lines of credit 92,998 91,606 41,921 32,130 RICs and auto loans 1,242,960 1,174,317 204,193 191,370 Personal unsecured loans — — — — Other consumer 4,848 6,325 63 34 Total consumer loans 1,439,758 1,432,420 285,271 321,842 Total non-accrual loans 1,762,934 1,738,635 544,729 536,401 OREO 3,960 29,799 — — Repossessed vehicles 232,614 204,653 — — Foreclosed and other repossessed assets 944 3,247 — — Total OREO and other repossessed assets 237,518 237,699 — — Total non-performing assets $ 2,000,452 $ 1,976,334 $ 544,729 $ 536,401 (1) Interest income recognized on nonaccrual loans was $26.3 million and $73.0 million for the three-month and nine-month periods ended September 30, 2021, respectively, compared to $21.8 million and $84.4 million for the three-month and nine-month periods ended September 30, 2020, respectively. NOTE 3. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Age Analysis of Past Due Loans The Company generally considers an account delinquent when an obligor fails to pay substantially all (defined as 90%) of the scheduled payment by the due date. When an account is deferred, the loan is returned to accrual status during the deferral period and accrued interest related to the loan is evaluated for collectability. The age of amortized cost in past due loans and accruing loans 90 days or greater past due disaggregated by class of financing receivables is summarized as follows: As of: September 30, 2021 (in thousands) 30-89 90 Total Current Total Amortized Cost Commercial: CRE (3) $ 24,743 $ 49,067 $ 73,810 $ 7,393,232 $ 7,467,042 $ — C&I (1) 27,356 22,439 49,795 15,000,779 15,050,574 — Multifamily 36,505 25,840 62,345 7,286,327 7,348,672 — Other commercial 179,750 2,884 182,634 7,899,740 8,082,374 — Consumer: Residential mortgages (2) 75,958 72,590 148,548 5,787,378 5,935,926 — Home equity loans and lines of credit 19,914 60,829 80,743 3,533,729 3,614,472 — RICs and auto loans (4) 3,153,639 229,792 3,383,431 39,928,583 43,312,014 — Personal unsecured loans 7,977 5,554 13,531 1,528,784 1,542,315 2,214 Other consumer 3,007 306 3,313 155,570 158,883 — Total $ 3,528,849 $ 469,301 $ 3,998,150 $ 88,514,122 $ 92,512,272 $ 2,214 (1) C& I loans includes $100.1 million of LHFS at September 30, 2021.

LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) 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. 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. NOTE 3. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Each commercial loan is evaluated to determine its risk rating at least annually. The indicators represent the rating for loans as of the date presented based on the most recent assessment performed.

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 CECL loss calculation incorporates the refreshed LTV information to update the distribution of defaulted loans by LTV as well as the associated LGD 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. FICO scores are refreshed quarterly, where possible. The indicators disclosed represent the credit scores for loans as of the date presented based on the most recent assessment performed. NOTE 3.

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 as of September 30, 2021: (in thousands) CBB C&I CRE & VF CIB SC Total Goodwill at September 30, 2021 $ 297,802 $ 52,198 $ 1,095,071 $ 131,130 $ 1,019,960 $ 2,596,161 During the three-month and nine-month periods ended September 30, 2021, there were no disposals, additions, impairments or re-allocations of goodwill. 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, 2020 using generally accepted valuation methods. As a result of that impairment test, no goodwill impairment was identified. NOTE 5. GOODWILL AND OTHER INTANGIBLES (continued) During the second quarter of 2020, primarily due to the ongoing economic impacts of the COVID-19 pandemic, the Company determined that a goodwill triggering event occurred for the CBB, C&I, and CRE & VF reporting units. Based on its goodwill impairment analysis performed as of June 30, 2020, the Company concluded that a goodwill impairment charge of $1.6 billion and $0.3 billion was required for the CBB and C&I reporting units, respectively. The CRE & VF reporting unit’s estimated fair value exceeded its carrying value by less than 5%. The goodwill allocated to these reporting units has become more sensitive to impairment as the valuation is highly correlated with forecasted interest rates, credit costs, and other factors. During the fourth quarter of 2020, the Company implemented organizational changes which resulted in the transfer of Upper Business Banking customers into the C&I segment from the CBB segment. Refer to Note 18 to these Consolidated Financial Statements for additional details on the Company's reportable segments. As a result of the re-organization, the Company re-allocated approximately $25.1 million of goodwill from the CBB reporting unit to the C&I reporting unit. Upon re-allocation, the Company performed a post evaluation for impairment on the CBB and C&I reporting units utilizing assumptions consistent with our October 1, 2020 impairment test and noted no impairment.

Variable Interest Entity and Securitizations [Abstract]
VIEs	VIEs The Company transfers RICs and vehicle leases into newly-formed Trusts that then issue one or more classes of notes payable backed by the collateral. The Company’s continuing involvement with these Trusts is in the form of servicing the assets and, generally, through holding residual interests in the Trusts. The Trusts are considered VIEs under GAAP, and the Company may or may not consolidate these VIEs on its Condensed Consolidated Balance Sheets. For further description of the Company’s securitization activities, involvement with VIEs and accounting policies regarding consolidation of VIEs, see Part II, Item 8 - Financial Statements and Supplementary Data (Note 8) in the Company's 2020 Annual Report on Form 10-K. On-balance sheet VIEs The assets of consolidated VIEs presented based upon the legal transfer of the underlying assets in order to reflect legal ownership, that can be used only to settle obligations of the consolidated 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: (in thousands) September 30, 2021 December 31, 2020 Assets Restricted cash $ 1,682,654 $ 1,737,021 LHFS 113,313 581,938 LHFI 21,785,308 22,572,549 Operating lease assets, net 15,529,610 16,391,107 Various other assets 706,130 791,306 Total Assets $ 39,817,015 $ 42,073,921 Liabilities Notes payable $ 30,632,558 $ 31,700,709 Various other liabilities 107,743 84,922 Total Liabilities $ 30,740,301 $ 31,785,631 Certain amounts shown above are greater than the amounts shown in the corresponding line items in the accompanying Condensed Consolidated Balance Sheets due to intercompany eliminations between the VIEs and other entities consolidated by the Company. For example, for most of its securitizations, the Company retains one or more of the lowest tranches of bonds. Rather than showing investment in bonds as an asset and the associated debt as a liability, these amounts are eliminated in consolidation as required by GAAP. The Company retains servicing rights for receivables transferred to the Trusts and receives a monthly servicing fee on the outstanding principal balance. Supplemental fees, such as late charges, for servicing the receivables are reflected in Miscellaneous income, net. As of September 30, 2021 and December 31, 2020, the Company was servicing $26.1 billion and $27.7 billion, respectively, of gross RICs that have been transferred to consolidated Trusts.

Banking and Thrift, Other Disclosures [Abstract]
SECURITIES FINANCING AGREEMENTS	SECURITIES FINANCING AGREEMENTS The Company may enter into Securities Financing Agreements primarily to deploy the Company’s excess cash and investment positions. Securities Financing Agreements are treated as collateralized financings and are included i n "F ederal funds sold and securities purchased under resale agreements or similar arrangements" an d "Federal funds purchased and securities loaned or sold under repurchase agreements" on the Company’s Condensed Consoli dated Balance Sheets. Resale and repurchase agreements are generally carried at the amounts at which the securities will be subsequently sold or repurchased. These agreements are generally carried at the amount of cash collateral advanced or received plus accrued interest. Where appropriate under applicable accounting guidance, Securities Financing Agreements with the same counterparty are reported on a net basis. Refer to Note 1 for further discussion of the offsetting of assets and liabilities. Securities transferred to counterparties under repurchase agreements and securities lending transactions continue to be recognized on the Condensed Consolidated Balance Sheets, are measured at fair value, and are included i n Investment securities AFS on the Company’s Condensed Consoli dated Balance Sheets . Securities received from counterparties under reverse repurchase agreements and securities borrowed transactions are not recognized on the Condensed Consolidated Balance Sheets unless the counterparty defaults. The securities transferred under Securities Financing Agreements typically are U.S. Treasury and agency securities or residential agency MBS. In general, the securities transferred can be sold, re-pledged or otherwise used by the party in possession. No restrictions exist on the use of cash collateral by either party. The Company may be exposed to counterparty risk, with such risk managed by performing assessments independent of business line managers, and establishing concentration limits on each counterparty. Additionally, these transactions include collateral arrangements that require the fair values of the underlying securities to be determined daily, resulting in cash being obtained or refunded to counterparties to maintain specified collateral levels. These financing transactions do not create material credit risk given the collateral provided and the related monitoring process.

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 13 to these Condensed 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 September 30, 2021, derivatives in this category had a fair value of $0.6 million. The credit ratings of the Company and SBNA are currently considered investment grade. During the third quarter of 2021, 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 September 30, 2021 and December 31, 2020, the aggregate fair value of all derivative contracts with credit risk contingent features (i.e., those containing collateral posting or termination provisions based on the Company's ratings) that were in a net liability position totaled $8.5 million and $9.9 million, respectively. The Company had $8.6 million and $3.9 million in cash and securities collateral posted to cover those positions as of September 30, 2021 and December 31, 2020, 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. Fair Value Hedges During the second quarter of 2021, the Company began entering into derivatives to hedge the risk of changes in fair value of a portion of its LHFI portfolio. These derivatives are designated as fair value hedges at inception. The gains/(losses) from changes in the fair value of the hedging derivative and the offsetting gains/(losses) from changes in the fair value of the related underlying hedged items are reporting in the same line item in the Condensed Consolidated Statements of Operations as earnings from the hedged items. The cumulative fair value hedge basis adjustments included in the carrying amount of hedged assets is reversed through earnings in future periods as an adjustment to yield. The Company includes gains/(losses) on the hedging derivatives and the related hedged items in the assessment of hedge effectiveness. All of these swaps have been deemed highly effective fair value hedges. The last of the hedges is scheduled to expire in 2026. NOTE 12. DERIVATIVES (continued) 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 AOCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and is presented in the same Condensed 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 2027. The Company includes all components of each derivative's gain or loss in the assessment of hedge effectiveness. As of September 30, 2021, the Company estimated that approximately $24.3 million of unrealized gains included in AOCI would be reclassified to earnings during the subsequent twelve months as the future cash flows occur. Derivatives Designated in Hedge Relationships – Notional and Fair Values Derivatives designated as accounting hedges at September 30, 2021 and December 31, 2020 included: (dollars in thousands) Notional Asset Liability Weighted Average Receive Rate Weighted Average Pay Weighted Average Life September 30, 2021 Fair value hedges: Cross-currency swaps $ 14,743 $ 421 $ 22 1.34 % 7.3 % 1.84 Interest rate swaps $ 39,300 $ 139 $ 275 0.05 % 0.71 % 4.74 Cash flow hedges: Pay variable - receive fixed interest rate swaps 11,945,000 78,699 44,857 0.99 % 0.08 % 2.19 Interest rate floor 925,000 612 — 0.05 % — % 1.93 Total $ 12,924,043 $ 79,871 $ 45,154 0.92 % 0.08 % 2.18 December 31, 2020 Cash flow hedges: Pay fixed — receive variable interest rate swaps $ 2,450,000 $ 124 $ 70,589 0.18 % 1.50 % 1.90 Pay variable - receive fixed interest rate swaps 8,745,000 150,206 182 1.16 % 0.14 % 2.12 Interest rate floor 3,525,000 27,507 — 1.28 % — % 1.10 Total $ 14,720,000 $ 177,837 $ 70,771 1.03 % 0.33 % 1.84 During 2018, 2019, and 2020, SC entered into interest rate swap agreements with an aggregate notional amount of $2.2 billion. The interest rate swaps were to be used to hedge SC’s variable rate debt and had maturity dates ranging from two 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. NOTE 12. DERIVATIVES (continued) 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. 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. NOTE 12.

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 applicable master agreement. The Company's financial instruments, including resell and repurchase agreements, securities lending arrangements, derivatives and cash collateral, may be eligible for offset on its Condensed Consolidated Balance Sheets. The Company has elected to present derivative balances on a gross basis even if the derivative is subject to a legally enforceable nettable ISDA Master Agreement for all trades executed after April 1, 2013. Collateral that is received or pledged for these transactions is disclosed within the “Gross Amounts Not Offset in the Condensed Consolidated Balance Sheets” section of the tables below. Prior to April 1, 2013, the Company had elected to net all caps, floors, and interest rate swaps when it had an ISDA Master Agreement with the counterparty. The collateral received or pledged in connection with these transactions is disclosed within the “Gross Amounts Offset in the Condensed Consolidated Balance Sheets" section of the tables below. NOTE 12.

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE The fair value hierarchy categorizes the underlying assumptions and inputs to valuation techniques that are used to measure fair value into three levels. The three fair value hierarchy classification levels are defined 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. See Note 1 of the 2020 Annual Report on Form 10-K for a broad discussion of fair value measurement techniques. 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 determin ed 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. NOTE 13. FAIR VALUE (continued) The Company values assets and liabilities based on the principal market in which each would be sold (in the case of assets) or transferred (in the case of liabilities). The principal market is the forum with the greatest volume and level of activity. In the absence of a principal market, the valuation is based on the most advantageous market. In the absence of observable market transactions, the Company considers liquidity valuation adjustments to reflect the uncertainty in pricing the instruments. The fair value of a financial asset is measured on a stand-alone basis and cannot be measured as a group, with the exception of certain financial instruments held and managed on a net portfolio basis. In measuring the fair value of a nonfinancial asset, the Company assumes the highest and best use of the asset by a market participant, not just the intended use, to maximize the value of the asset. The Company also considers whether any credit valuation adjustments are necessary based on the counterparty's credit quality. Any models used to determine fair values or validate dealer quotes based on the descriptions below are subject to review and testing as part of the Company's model validation and internal control testing processes. The 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. 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. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present the assets and liabilities that are measured at fair value on a recurring basis by major product category and fair value hierarchy as of September 30, 2021 and December 31, 2020: (in thousands) Level 1 Level 2 Level 3 Balance at Level 1 Level 2 Level 3 Balance at Financial assets: U.S. Treasury securities $ — $ 90,688 $ — $ 90,688 $ — $ 170,653 $ — $ 170,653 Corporate debt — 239,805 — 239,805 — 155,715 — 155,715 ABS — 544,525 — 544,525 — 58,945 50,393 109,338 MBS — 10,501,834 — 10,501,834 — 10,877,783 — 10,877,783 Investment in debt securities AFS (2) — 11,376,852 — 11,376,852 — 11,263,096 50,393 11,313,489 Other investments - trading securities — 38,748 — 38,748 — 40,435 — 40,435 RICs HFI (3) — 3,774 35,616 39,390 — — 50,391 50,391 LHFS (1)(4) — 194,078 — 194,078 — 265,428 — 265,428 MSRs — — 79,580 79,580 — — 77,545 77,545 Other assets - derivatives (2) — 770,816 4,162 774,978 — 1,205,690 13,400 1,219,090 Total financial assets (5) $ — $ 12,384,268 $ 119,358 $ 12,503,626 $ — $ 12,774,649 $ 191,729 $ 12,966,378 Financial liabilities: Other liabilities - derivatives (2) — 689,828 1,789 691,617 — 1,068,074 3,952 1,072,026 Total financial liabilities $ — $ 689,828 $ 1,789 $ 691,617 $ — $ 1,068,074 $ 3,952 $ 1,072,026 (1) LHFS disclosed on the Condensed Consolidated Balance Sheets also includes LHFS that are held at the lower of cost or fair value and are not presented within this table.

(3) RI Cs collateralized by vehicle titles at SC and RV/marine loans at SBNA. (4) Residential mortgage loans. (5) Approximately $119.4 million of these financial assets were measured using model-based techniques, or Level 3 inputs, and represented approximately 1.0% of total assets measured at fair value on a recurring basis and approximately 0.1% of total consolidated assets. NOTE 13. FAIR VALUE (continued) 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. 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 and are classified as Level 3. Realized gains and losses on investments in debt securities are recognized in the Condensed 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. The estimated fair value of all RICs HFI is estimated using a DCF model and are classified as Level 3. LHFS The Company's LHFS portfolios that are measured at fair value on a recurring basis consist primarily of residential mortgage LHFS. The fair values of LHFS are estimated using published forward agency prices to agency buyers such as FNMA and FHLMC. The majority of the residential mortgage LHFS portfolio is sold to these two agencies. The fair value is determined using current secondary market prices for portfolios with similar characteristics, adjusted for servicing values and market conditions. These loans are regularly traded in active markets, and observable pricing information is available from market participants. The prices are adjusted as necessary to include the embedded servicing value in the loans as well as the specific characteristics of certain loans that are priced based on the pricing of similar loans. These adjustments represent unobservable inputs to the valuation, and are not significant given the relative insensitivity of the value to changes in these inputs to the fair value of the loans. Accordingly, residential mortgage LHFS are classified as Level 2. Gains and losses on residential mortgage LHFS are recognized in the Condensed Consolidated Statements of Operations through Miscellaneous income, net. See further discussion below in the section captioned "FVO for Financial Assets and Financial Liabilities." NOTE 13. FAIR VALUE (continued) 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 (reflective of a market participant’s return on an investment for similar assets), servicing costs, and other economic factors which are determined based on current market conditions. Historically, servicing costs and discount rates have been less volatile than prepayment rates, which are directly correlated with changes in market interest rates. Increases in prepayment rates, 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. Assumptions incorporated into the residential MSR valuation model reflect management's best estimate of factors that a market participant would use in valuing the residential MSRs, as well as future expectations. 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 brokers are obtained. Brokers provide a range of values based upon their own 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 of the brokers' ranges, management will assess whether a valuation adjustment is warranted. The residential MSRs value is considered to represent a reasonable estimate of fair value. MSR’s are classified as Level 3. Gains and losses on MSRs are recognized on the Condensed Consolidated Statements of Operations through Miscellaneous income, net. Significant assumptions used in the valuation of residential MSRs include CPRs and the discount rate. 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. Below is a sensitivity analysis of the most significant inputs 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 $3.5 million and $6.9 million, respectively, at September 30, 2021. • A 10% and 20% increase in the discount rate would decrease the fair value of the residential servicing asset by $2.4 million and $4.7 million, respectively, at September 30, 2021. 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. NOTE 13. FAIR VALUE (continued) 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).

(2) The Company transferred RICs from Level 2 to Level 3 during 2020 because the fair value for these assets cannot be determined by using readily observable inputs. There were no other transfers into or out of Level 3 during the three-month and nine-month periods ended September 30, 2021 or 2020. NOTE 13. FAIR VALUE (continued) 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 $ — $ 18,005 $ 696 $ 18,701 $ — $ 32,609 $ 11,925 $ 44,534 Foreclosed assets — (279) — (279) — 8,232 23,528 31,760 Vehicle inventory — 271,040 — 271,040 — 313,754 — 313,754 LHFS (1) — — 496,489 496,489 — — 1,960,768 1,960,768 Auto loans impaired due to bankruptcy — 204,594 — 204,594 — 191,785 — 191,785 (1) These amounts include zero and $0.9 billion of personal LHFS that were impaired as of September 30, 2021 and December 31, 2020, respectively. On March 16, 2021 the Company sold the personal lending portfolio. Refer to Note 1 for more information. 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 $12.7 million and $33.2 million at September 30, 2021 and December 31, 2020, respectively. Loans previously impaired which were not marked to fair value during the periods presented are excluded from this table. Foreclosed assets represent the recorded investment in assets taken during the period presented in foreclosure of defaulted loans, and are primarily comprised of commercial and residential real properties and generally measured at fair value less costs to sell. The fair value of the real property is generally determined using appraisals or other indications of market value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. The Company estimates the fair value of its vehicles, which are obtained either through repossession or lease termination, using historical auction rates and current market values of used cars. The Company's LHFS portfolios that are measured at fair value on a nonrecurring basis primarily consist of personal, commercial, and RICs LHFS. The estimated fair value of these LHFS is calculated based on a combination of estimated market rates for similar loans with similar credit risks and a DCF analysis in which the Company uses significant unobservable inputs on key assumptions, including historical default rates and adjustments to reflect voluntary prepayments, prepayment rates, discount rates reflective of the cost of funding, and credit loss expectations. The lower of cost or fair value adjustment for personal LHFS includes customer default activity and adjustments related to the net change in the portfolio balance during the reporting period. For loans that are considered collateral-dependent, such as certain bankruptcy loans, impairment is measured based on the fair value of the collateral less its estimated cost to sell. For the underlying collateral, the estimated fair value is obtained using historical auction rates and current market levels of the collateral securing the loans. NOTE 13. FAIR VALUE (continued) The estimated fair value of goodwill is valued using unobservable inputs and is classified as Level 3 at October 1 annually or more frequently if impairment indicators are present at an interim date. Fair value is calculated using widely-accepted valuation techniques, such as the guideline public company market approach (earnings and price-to-tangible book value multiples of comparable public companies) and the income approach (the DCF method). The Company uses a combination of these accepted methodologies to determine the fair valuation of reporting units. Several factors are taken into account, including actual operating results, future business plans, economic projections, and market data. On a quarterly basis, the Company assesses whether or not impairment indicators are present. For information on the Company's goodwill impairment test and the results of the most recent goodwill impairment test, see Note 5 for a description of the Company's goodwill valuation methodology. Fair Value Adjustments The following table presents the increases and decreases in value of certain assets that are measured at fair value on a nonrecurring basis for which a fair value adjustment has been included in the Condensed Consolidated Statements of Operations relating to assets held at period-end: Three-Month Period Ended September 30, Nine-Month Period Ended September 30, (in thousands) Statement of Operations Location 2021 2020 2021 2020 (2) Impaired LHFI Credit loss expense $ (1,021) $ (12,036) $ (6,008) $ (5,883) Foreclosed assets Miscellaneous income, net (1) — (736) (321) (3,857) LHFS Miscellaneous income — (56,598) — (387,900) Auto loans impaired due to bankruptcy Credit loss expense — — — — (1) Gains are disclosed as positive numbers while losses are shown as a negative number regardless of the line item being affected.

FAIR VALUE (continued) 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 Condensed 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 poste

INCOME TAXES

INCOME TAXES	9 Months Ended
	Sep. 30, 2021
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES An income tax expense of $227.3 million and a benefit of $53.3 million were recorded for the three-month periods ended September 30, 2021 and 2020, respectively. An income tax expense of $885.8 million and a benefit of $272.9 million were recorded for the nine-month periods ended September 30, 2021 and 2020, respectively. This resulted in an ETR of 21.0% and (6.5)% for the three-month periods ended September 30, 2021 and 2020, respectively, and 23.3% and 19.3% for the nine-month periods ended September 30, 2021 and 2020, respectively. The increase in the ETR for the three-month and nine-month periods ended September 30, 2021, compared to the three-month and nine-month periods ended September 30, 2020, was primarily the result of expected pre-tax income for 2021, compared to a pre-tax loss in 2020, and the impairment of goodwill in 2020 that was non-deductible for tax purposes. 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) With few exceptions, the Company is no longer subject to federal, state and non-U.S. income tax examinations by tax authorities for years prior to 2006. The Company applies an aggregate portfolio approach whereby income tax effects from AOCI are released only when an entire portfolio (i.e., all related units of account) of a particular type is liquidated, sold or extinguished. The Company had a net deferred tax liability balance of $602.8 million at September 30, 2021 (consisting of a deferred tax asset balance of $45.6 million and a deferred tax liability balance of $648.4 million with respect to jurisdictional netting), compared to a net deferred tax liability balance of $171.2 million at December 31, 2020 (consisting of a deferred tax asset balance of $11.1 million and a deferred tax liability balance of $182.4 million). The $431.6 million increase in net deferred liability for the nine-month period ended September 30, 2021 was primarily due to a decrease in net operating loss carryforwards.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES AND GUARANTEES	COMMITMENTS, CONTINGENCIES, AND GUARANTEES Off-Balance Sheet Risk - Financial Instruments In the normal course of business, the Company utilizes a variety of financial instruments with off-balance sheet risk to meet the financing needs of its customers and manage its exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, letters of credit, loans sold with recourse, forward contracts, and interest rate and cross currency swaps, caps and floors. These financial instruments may involve, to varying degrees, elements of credit, liquidity, and interest rate risk in excess of the amount recognized on the Condensed Consolidated Balance Sheets. The contractual or notional amounts of these financial instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit, letters of credit and loans sold with recourse is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. For forward contracts and interest rate swaps, caps and floors, the contract or notional amounts do not represent exposure to credit loss. The Company controls the credit risk of its forward contracts and interest rate swaps, caps and floors through credit approvals, limits and monitoring procedures. See Note 12 to these Condensed Consolidated Financial Statements for discussion of all derivative contract commitments. NOTE 16. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) The following table details the amount of commitments at the dates indicated: Other Commitments September 30, 2021 December 31, 2020 (in thousands) Commitments to extend credit $ 28,118,571 $ 30,883,502 Letters of credit 1,324,186 1,432,764 Commitments to sell loans 33,038 49,791 Recourse exposure on sold loans 19,621 26,362 Total commitments $ 29,495,416 $ 32,392,419 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 September 30, 2021 and December 31, 2020 were $4.1 billion and $5.4 billion, respectively, of commitments that can be canceled by the Company without notice. Commitments to extend credit also include amounts committed by the Company to fund its investments in CRA, LIHTC, and other equity method investments in which it is a limited partner. Letters of Credit The Company’s letters of credit meet the definition of a guarantee. Letters of credit commit the Company to make payments on behalf of its customers if specified future events occur. The guarantees are primarily issued to support public and private borrowing arrangements. The weighted average term of these commitments at September 30, 2021 was 15.9 months. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. In the event of a requested draw by the beneficiary that complies with the terms of the letter of credit, the Company would be required to honor the commitment. The Company has various forms of collateral for these letters of credit, including real estate assets and other customer business assets. The maximum undiscounted exposure related to these commitments at September 30, 2021 was $1.3 billion. The fees related to letters of credit are deferred and amortized over the lives of the respective commitments, and were immaterial to the Company’s financial statements at September 30, 2021. 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. The credit risk associated with letters of credit is monitored using the same risk rating system utilized within the loan and financing lease portfolio. As of September 30, 2021 and December 31, 2020, the liability related to unfunded lending commitments was $135.5 million and $146.5 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 16. 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. Securities Borrowed and Lending Subject to Repurchase or Resale Agreements In the second quarter of 2021, the Company began entering into Securities Financing Agreements primarily to deploy the Company’s excess cash and investments. Refer to Note 11 to these Condensed Consolidated Financial Statements for further discussion of the Company's commitments in connection with those agreements. SC Commitments The following table summarizes liabilities recorded for commitments and contingencies as of September 30, 2021 and December 31, 2020, all of which are included in Accounts payable and accrued expenses in the accompanying Condensed Consolidated Balance Sheets: Agreement or Legal Matter Commitment or Contingency September 30, 2021 December 31, 2020 (in thousands) MPLFA Revenue-sharing and gain/(loss), net-sharing payments $ 70,675 $ 43,778 Agreement with Bank of America Servicer performance fee 462 1,200 Agreement with CBP Loss-sharing payments 286 181 Other contingencies Consumer arrangements 29,070 22,155 Following is a description of the agreements and legal matters pursuant to which the liabilities in the preceding table were recorded. MPLFA Under the terms of the MPLFA, SC must make revenue sharing payments to Stellantis and also must share with Stellantis when residual gains/(losses) on leased vehicles exceed a specified threshold. The MPLFA 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 Stellantis retail financing. In turn, Stellantis must provide designated minimum threshold percentages of its Subvention business to SC. Agreement with Bank of America Until January 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 retained servicing on the sold loans and owes CBP a loss-sharing payment capped at 0.5% of the original pool balance if losses exceed a specified threshold, established on a pool-by-pool basis. Loss-sharing payments are due the month in which net losses exceed the established threshold of each loan sale. NOTE 16. 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 through April 2022. During the first quarter in 2021, SC completed the sale of the Bluestem personal lending portfolio to a third party. In addition, SC executed a forward flow sale agreement with a third party to purchase all personal lending receivables that SC purchases from Bluestem through the term of the agreement with Bluestem. As of December 31, 2020, the total unused credit available to customers was $2.7 billion. In 2021, SC purchased $0.3 billion of receivables out of the $2.7 billion of unused credit available to customers as of December 31, 2020. In 2020, SC purchased $1.2 billion of receivables out of the $3.0 billion of unused credit available to customers as of December 31, 2019. In addition, SC purchased $24.9 million and $151.2 million of receivables related to newly-opened customer accounts during the nine-month periods ended September 30, 2021 and 2020, 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. 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 by SC, it will pay Nissan a referral fee. In connection with the sale of RICs through securitizations and other sales, SC has made standard representations and warranties customary to the consumer finance industry. Violations of these representations and warranties may require SC to repurchase loans previously sold to on- or off-balance sheet Trusts or other third parties. As of September 30, 2021, 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 RIC sale agreements is not expected to have a material adverse effect on the Company's or SC’s business, consolidated financial position, results of operations, or cash flows. Santander has provided guarantees on the covenants, agreements, and obligations of SC under the governing documents of its warehouse facilities and privately issued amortizing notes. These guarantees are limited to the obligations of SC as servicer. In November 2015, SC executed a forward flow asset sale agreement with a third party under the terms of which SC is committed to sell $350.0 million in charged-off loan receivables in bankruptcy status on a quarterly basis. However, any sale of more than $275.0 million is subject to a market price check. The remaining aggregate commitment as of September 30, 2021 and December 31, 2020 not subject to a market price check was $6.2 million and $15.3 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 16. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) Legal and Regulatory Proceedings The Company, including its subsidiaries, is and in the future periodically expects to be party to, or otherwise involved in, various claims, disputes, lawsuits, investigations, regulatory matters and other legal matters and proceedings that arise in the ordinary course of business. In view of the inherent difficulty of predicting the outcome of any such claim, 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. It is reasonably possible that actual outcomes or losses may differ materially from the Company's current assessments and estimates, and any adverse resolution of any of these matters against it could materially and adversely affect the Company's business, financial position, liquidity, and results of operations. In accordance with applicable accounting guidance, the Company establishes an accrued liability for legal and regulatory proceedings when those matters present material loss contingencies that are both probable and estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. When a loss contingency is not both probable and estimable, the Company does not establish an accrued liability. As a legal or regulatory proceeding develops, the Company, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether the matter presents a material loss contingency that is probable and estimable. If a determination is made during a given quarter that a material loss contingency is probable and estimable, an accrued liability is established during such quarter with respect to such loss contingency, and the Company continues to monitor the matter for further developments that could affect the amount of the accrued liability previously established. As of September 30, 2021 and December 31, 2020, the Company accrued aggregate legal and regulatory liabilities of approximately $28.7 million and $109.5 million, respectively. Further, the Company estimates the aggregate range of reasonably possible losses for legal and regulatory proceedings, in excess of reserves established, of up to approximately $15.6 million as of September 30, 2021. Set forth below are descriptions of the material lawsuits, regulatory matters and other legal proceedings to which the Company is subject. SBNA Matters Mortgage Escrow Interest Putative Class Action SBNA is a defendant in a putative class action lawsuit in the United States District Court, Southern District of New York, captioned Daniel and Rebecca Ruf-Tepper v. Santander Bank, N.A., No. 20-cv-00501. The Tepper Lawsuit, filed in January 2020, alleges that SBNA is obligated to pay interest on mortgage escrow accounts pursuant to state law. Plaintiffs filed an amended complaint and SBNA has filed a motion to dismiss. On July 12, 2021, plaintiffs filed a motion seeking preliminary approval of a settlement with SBNA pursuant to which SBNA will pay a total of $2 million to resolve the litigation. Overtime Putative Class Action SBNA is a defendant in a putative class action lawsuit in the United States District Court, District of New Jersey, captioned Crystal Sanchez, et. Al. v. Santander Bank, N.A., No. 17-cv-5775. The lawsuit alleges that SBNA failed to pay overtime to current and former branch operations managers. The Court denied SBNA’s motion to dismiss. Plaintiff's motion seeking to amend its complaint to add additional state law claims is fully briefed. NOTE 16. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) SC Matters Shareholder Derivative Lawsuits Seattle City Employees Retirement System v. Santander Holdings USA, Inc., et al: In November 2020, a shareholder derivative complaint was filed in the Court of Chancery of the State of Delaware, captioned Seattle City v. Santander Holdings USA, Inc., C.A. No. 2020-0977-AG B. The plaintiff seeks unspecified monetary damages and other injunctive relief in the complaint. The complaint alleges, among other things, that SHUSA and the current director breached their fiduciary duties by causing SC to engage in share repurchases for the purpose of increasing SHUSA’s ownership of SC above 80%, which the complaint alleges would allow SHUSA to obtain tax and other benefits not available to the rest of SC’s shareholders. The defendants filed an answer to the complaint. Caldwell v. Santander Consumer USA Holdings Inc. : In September 2020, a purported shareholder of SC Common Stock filed a complaint against SC and its Board of Directors in the United States District Court for the Southern District of New York, captioned Craig Caldwell v. Santander Consumer USA Holdings Inc., 1:21-cv-07842, alleging violations of the Exchange Act when the Board allegedly authorized the filing of a materially incomplete and misleading Solicitation/Recommendation Statement with the SEC in connection with SHUSA’s proposed purchase of the remaining shares of SC Common Stock not already owned by SHUSA. The plaintiff seeks to enjoin the defendants from proceeding with the proposed transaction. Consumer Lending Cases The Company and its subsidiaries are 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: Mississippi Attorney General Lawsuit: In January 2017, Mississippi Attorney General filed a lawsuit against SC in the Chancery Court of the First Judicial District of Hinds County, 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 . In July 2021, SC and the state of Mississippi entered into a settlement agreement resolving this matter for a monetary payment of $3.7 million to the state of Mississippi. On July 21, 2021, the Mississippi Attorney General publicly announced the settlement agreement. 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 Arbitrations As of September 30, 2021, SSLLC had received 773 FINRA arbitration cases related to Puerto Rico bonds and Puerto Rico CEFs 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 19 arbitration cases pending as of September 30, 2021. The Company has experienced a decrease in the volume of claims since September 30, 2019 and does not expect to see a significant increase in claims in future periods. NOTE 16. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) Puerto Rico Putative Class Action: SSLLC, SBC, 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. On July 22, 2020, the District Court dismissed the complaint. Plaintiffs have appealed to the United States Court of Appeals for the First Circuit. 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. On September 16, 2020, the defendants moved to dismiss the complaint. On June 2, 2021, the court denied the defendants’ motion to dismiss. Defendants are seeking to appeal the decision. On October 28, 2020, bond insurer Ambac Assurance Corporation filed an amended complaint in Puerto Rico state court adding SSLLC and four other Puerto Rico municipal bond underwriters to a pending suit against seven underwriters, alleging that the underwriters made misrepresentations in connection with the issuance of the debt and that Ambac relied on such misrepresentations in agreeing to insure certain of the bonds. The amended complaint alleges damages of not less than $508 million. On July 30, 2021, the court granted the defendants’ motion to dismiss the complaint. Plaintiffs have appealed. On November 27, 2020, bond insurer Financial Guaranty Insurance Company filed suit in Puerto Rico state court against twelve Puerto Rico municipal bond underwriters, including SSLLC, alleging that the underwriters made misrepresentations in connection with the issuance of the debt and that Financial Guaranty Insurance Company relied on such misrepresentations in agreeing to insure certain of the bonds. The complaint alleges damages of not less than $447 million. On February 1, 2021, the defendants moved to dismiss the complaint. On July 9, 2021, the court granted the defendants’ motion to dismiss. Plaintiff has appealed. 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.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS The Company and its affiliates have various debt and derivative agreements with Santander. For further details of these agreements, see Note 10 and Note 20 to the Consolidated Financial Statements of the Company's Annual Report on Form 10-K for the year ended December 31, 2020.

SC provides servicing on all loans originated under this arrangement. For the three-month and nine-month periods ended September 30, 2021, servicing fee income of $2.0 million and $7.3 million, respectively, was recognized in the Condensed Consolidated Statements of Operations compared to $4.5 million and $15.7 million for the three-month and nine-month periods ended September 30, 2020, respectively.

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. The Company has identified the following reportable segments: CBB, C&I, CRE & VF, CIB, and SC. • The CBB segment includes the products and services provided to Bank consumer and small business banking customers, including consumer deposit, small 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. SBNA also finances indirect consumer automobile RICs and leases through intercompany agreements with SC. In addition, SBNA 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 lower middle market commercial customers and 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. This category also includes SBNA’s community development finance activities, including originating CRA-eligible loans and making CRA-eligible investments. • 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 MPLFA, SC offers a full spectrum of auto financing products and services to Stellantis customers and dealers under the CCAP 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 SBNA and SC are eliminated in the consolidated results of the Company. SBNA also offers customer-related derivatives to hedge interest rate risk, and for C&I and CIB offers derivatives relating to foreign exchange and lending arrangements. See Note 11 to the Consolidated Financial Statements for additional details. The Other category includes certain immaterial subsidiaries such as BSI, SSLLC, and several other subsidiaries, the unallocated interest expense on the Company's borrowings and other debt obligations and certain unallocated corporate income and indirect expenses. NOTE 18. BUSINESS SEGMENT INFORMATION (continued) The Company’s segment results, excluding SC and the entities that have been transferred to the Company as 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 Condensed Consolidated Financial Statements with respect to activities specifically attributable to each business line. However, the preparation of business line results requires management to establish methodologies to allocate funding costs and benefits, expenses and other financial elements to each line of business. Where practical, the results are adjusted to present consistent methodologies for the segments. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. The implementation of these enhancements to the internal management reporting methodology may materially affec t 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. During the fourth quarter of 2020, the Company implemented organizational changes to meet the evolving needs of its business customers including the re-alignment of Upper Business Banking with the C&I segment from the CBB segment. In addition, the Company moved the assets associated with its Community Development Finance business from its “Other” category to the CRE&VF segment to align its LIHTC assets with similar CRE assets and liabilities. All prior period results have been revised for these segment changes. 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.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These Condensed Consolidated Financial Statements include the accounts of the Company and its consolidated subsidiaries, including certain 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 Condensed Consolidated Financial Statements have been prepared in accordance with GAAP and pursuant to SEC regulations. In the opinion of management, the accompanying Condensed Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary for a fair statement of the Consolidated Balance Sheets, Statements of Operations, Statements of Comprehensive Income, Statements of Stockholder's Equity and Statement of Cash Flow for the periods indicated, and contain adequate disclosure to make the information presented not misleading. Results of operations for the periods presented herein are not necessarily indicative of results of operations for the entire year. These financial statements should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2020. 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 consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates, and those differences may be material. The most significant estimates include the ACL, fair value measurements, expected end-of-term lease residual values, goodwill, and income taxes. These estimates, although based on actual historical trends and modeling, may potentially show significant variances over time.
Accounting Policies	Accounting Policies There have been no changes in the Company's accounting policies from those disclosed in the 2020 Annual Report on Form 10-K.
Credit Quality of Financing Receivables	Each commercial loan is evaluated to determine its risk rating at least annually. The indicators represent the rating for loans as of the date presented based on the most recent assessment performed. Amortized cost basis of loans in the commercial portfolio segment by credit quality indicator, class of financing receivable, and year of origination are summarized as follows:
Securities Borrowed and Loaned	The Company may enter into Securities Financing Agreements primarily to deploy the Company’s excess cash and investment positions. Securities Financing Agreements are treated as collateralized financings and are included i n "F ederal funds sold and securities purchased under resale agreements or similar arrangements" an d "Federal funds purchased and securities loaned or sold under repurchase agreements" on the Company’s Condensed Consoli dated Balance Sheets. Resale and repurchase agreements are generally carried at the amounts at which the securities will be subsequently sold or repurchased. These agreements are generally carried at the amount of cash collateral advanced or received plus accrued interest. Where appropriate under applicable accounting guidance, Securities Financing Agreements with the same counterparty are reported on a net basis. Refer to Note 1 for further discussion of the offsetting of assets and liabilities. Securities transferred to counterparties under repurchase agreements and securities lending transactions continue to be recognized on the Condensed Consolidated Balance Sheets, are measured at fair value, and are included i n Investment securities AFS on the Company’s Condensed Consoli dated Balance Sheets . Securities received from counterparties under reverse repurchase agreements and securities borrowed transactions are not recognized on the Condensed Consolidated Balance Sheets unless the counterparty defaults. The securities transferred under Securities Financing Agreements typically are U.S. Treasury and agency securities or residential agency MBS. In general, the securities transferred can be sold, re-pledged or otherwise used by the party in possession. No restrictions exist on the use of cash collateral by either party. The Company may be exposed to counterparty risk, with such risk managed by performing assessments independent of business line managers, and establishing concentration limits on each counterparty. Additionally, these transactions include collateral arrangements that require the fair values of the underlying securities to be determined daily, resulting in cash being obtained or refunded to counterparties to maintain specified collateral levels. These financing transactions do not create material credit risk given the collateral provided and the related monitoring process.
Fair Value Measurements	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. 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.
