BASIS OF PRESENTATION AND ACCOU

Accounting Policies [Abstract]
BASIS OF PRESENTATION AND ACCOUNTING POLICIES	BASIS OF PRESENTATION AND ACCOUNTING POLICIES Introduction Santander Holdings USA, Inc. ("SHUSA") is the parent company (the "Parent Company") of Santander Bank, National Association, (the "Bank" or "SBNA"), a national banking association, and Santander Consumer USA Holdings Inc. (together with its subsidiaries, "SC"), a consumer finance company focused on vehicle finance. SHUSA is headquartered in Boston, Massachusetts and the Bank's main office is in Wilmington, Delaware. SHUSA is a wholly-owned subsidiary of Banco Santander, S.A. ("Santander"). The Bank’s primary business consists of attracting deposits and providing other retail banking services through its network of retail branches, and originating small business loans, middle market, large and global commercial loans, multifamily loans, residential mortgage loans, home equity loans and lines of credit, and auto and other consumer loans throughout the Mid-Atlantic and Northeastern areas of the United States, focused throughout Pennsylvania, New Jersey, New York, New Hampshire, Massachusetts, Connecticut, Rhode Island, and Delaware. The Bank uses its deposits, as well as other financing sources, to fund its loan and investment portfolios. SC wholly owns Santander Consumer USA Inc., which is headquartered in Dallas, Texas, and is a specialized consumer finance company focused on vehicle finance and third-party servicing. Common shares of SC ("SC Common Stock") are listed for trading on the New York Stock Exchange (the "NYSE") under the trading symbol "SC." Basis of Presentation The accounting and financial reporting policies of the Company conform to accounting principles generally accepted in the United States of America ("GAAP"). These Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries, including the Bank, SC, and certain special purpose financing trusts utilized in financing transactions that are considered variable interest entities ("VIEs"). The Company consolidates VIEs for which it is deemed the primary beneficiary. The unaudited Condensed Consolidated Financial Statements have been prepared by the Company, pursuant to Securities and Exchange Commission ("SEC") regulations. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. All intercompany balances and transactions have been eliminated in consolidation. Additionally, where applicable, the Company's accounting policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. However, in the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary to present fairly the Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements of Stockholder's Equity and Condensed Consolidated Statements of Cash Flows for the periods indicated, and contain adequate disclosure for a fair presentation of this interim financial information. Corrections to Previously Reported Amounts We have made certain corrections to previously disclosed amounts to correct for errors related to the allowance for credit losses ("ACL"), troubled debt restructurings ("TDRs"), and the classification of subvention payments related to leased vehicles. The quantitative disclosure of impacts to all periods has been disclosed in the Company's Annual Report on Form 10-K as of December 31, 2015. The corrections to the ACL are a result of an error in our historical methodology for estimating the credit loss allowance for individually acquired retail installment contracts ("RICs"), specifically in regard to not estimating impairment on TDRs separately from a general credit loss allowance on loans not classified as TDRs, incorrectly applying a loss emergence period to the entire portfolio rather than only to loans not classified as TDRs, and incorrectly using SC's discount rates in the TDR methodology rather than the discount rate required for the Company related to the original purchase accounting discount. We have corrected the allowance methodology accordingly. The Company has also determined that subvention payments related to leased vehicles were incorrectly classified, within the Condensed Consolidated Statements of Operations , as an addition to Leased vehicle income rather than a reduction of Leased vehicle expense. There was no impact to net income as a result of this change. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) Certain footnote disclosures for interim periods within the year ended December 31, 2015 have been restated to reflect the effects of the corrections related to allowance methodology, as well as other corrections made in order for the footnote disclosure amounts to be in accordance with GAAP. Footnote disclosures that have been corrected are denoted with “As restated.” Footnote disclosures not affected are unchanged and reflect the disclosures made at the time of the previous filing. The following table summarizes the impact of the corrections on the Company's Condensed Consolidated Balance Sheet for the three-month period ended March 31, 2015 .

Refer to Note 17 of the Condensed Consolidated Financial Statements for the complete segmentation. Significant Accounting Policies Management identified accounting for consolidation, business combinations, the allowance for loan and lease losses and the reserve for unfunded lending commitments, goodwill, derivatives and hedge activities, and income taxes as the Company's critical accounting policies and estimates, in that they are important to the presentation of the Company's financial condition and results of operations and require management's most difficult, subjective and complex judgments as a result of the need to make estimates about the effect of matters that are inherently uncertain. These Condensed Consolidated Financial Statements should be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2015 . As of March 31, 2016 , with the exception of the items noted in the section "Changes in Accounting Policies" below, there have been no significant changes to the Company's accounting policies as disclosed in the Annual Report on Form 10-K for the year ended December 31, 2015 . Changes in Accounting Policies During the first quarter of 2016, the Company adopted the following Financial Accounting Standards Board ("FASB") Accounting Standards Updates ("ASUs"), none of which had a material impact to the Company's Consolidated Financial Statements: • The Company adopted ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (Topic 718) on a prospective basis. This ASU was issued by the FASB in June 2014 and requires that a performance target that affects vesting, and could be achieved after the requisite service period, be treated as a performance condition. Application of existing guidance in Accounting Standards Codification ("ASC") 718 as it relates to awards with performance conditions that affect vesting should continue to be used to account for such awards. • The Company also adopted ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items on a prospective basis . This ASU was issued by FASB in January 2015 and eliminates the concept of extraordinary items from GAAP, which previously required the separate classification, presentation, and disclosure of extraordinary events and transactions. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) • The Company also adopted ASU 2015-02, Consolidation (Topic 820): Amendments to the Consolidation Analysis, which the FASB issued in February 2015. This ASU changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Specifically, this ASU modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities (VOEs); eliminates the presumption that a general partner should consolidate a limited partnership; potentially changes the consolidation conclusions of reporting entities that are involved with VIEs, in particular those that have fee arrangements and related party arrangements; and provides a scope exception for reporting entities with interests held in certain money market funds and similar unregistered money market funds. As the adoption did not result in any significant impact to the Company’s consolidated financial statements, it did not result in a retrospective or modified retrospective application. • The Company also adopted ASU 2015-07, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent) on a retrospective basis . This ASU removes the requirement to categorize investments fair valued using the net asset value per share practical expedient within the fair value hierarchy. It also modifies disclosure requirements to include only investments for which the entity elects to use the practical expedient rather than the prior guidance which required disclosures for all investments eligible to use the practical expedient. • The Company also adopted ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement Period Adjustments on a prospective basis . This amendment eliminates the requirement to account for adjustments to provisional amounts recognized in a business combination retrospectively. Instead, the acquirer will recognize the adjustments to provisional amounts during the period in which the adjustments are determined, including the effect on earnings of any amounts the acquirer would have recorded in previous periods if the accounting had been completed at the acquisition date. Subsequent Events The Company evaluated events from the date of the Condensed Consolidated Financial Statements on March 31, 2016 through the issuance of these Condensed Consolidated Financial Statements and has determined that there have been no material events that would require recognition in its Condensed Consolidated Financial Statements or disclosure in the Notes to the Condensed Consolidated Financial Statements for the three-month period ended March 31, 2016 other than the transactions disclosed within Note 10 and Note 14 of these Condensed Consolidated Financial Statements .

RECENT ACCOUNTING DEVELOPMENTS

RECENT ACCOUNTING DEVELOPMENTS	3 Months Ended
	Mar. 31, 2016
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING DEVELOPMENTS	RECENT ACCOUNTING DEVELOPMENTS In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , superseding the revenue recognition requirements in ASC 605. This ASU requires an entity to recognize revenue for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendment includes a five-step process to assist an entity in achieving the main principle(s) of revenue recognition under ASC 605. In August 2015, the FASB issued ASU 2015-14, which formalized the deferral of the effective date of the amendment for a period of one-year from the original effective date. Following the issuance of ASU 2015-14, the amendment will be effective for the Company for the first annual period ending beginning after December 15, 2017. In March 2016, the FASB also issued ASU 2016-08, an amendment to the guidance in ASU 2014-09 which revises the structure of the indicators to provide indicators of when the entity is the principal or agent in a revenue transaction, and eliminated two of the indicators (“the entity’s consideration is in the form of a commission” and “the entity is not exposed to credit risk”) in making that determination. This amendment also clarifies that each indicator may be more or less relevant to the assessment depending on the terms and conditions of the contract. In April 2016, the FASB also issued ASU 2016-10, which clarifies the implementation guidance on identifying promised goods or services and on determining whether an entity's promise to grant a license with either a right to use the entity's intellectual property (which is satisfied at a point in time) or a right to access the entity's intellectual property (which is satisfied over time). The amendments, collectively, should be applied retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. Early adoption of the guidance is not permitted. The Company is currently evaluating the impact of adopting ASU 2014-09 and the related updates to it on its financial position, results of operations and disclosures. NOTE 2. RECENT ACCOUNTING DEVELOPMENTS (continued) In August 2014, the FASB also issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40). This ASU requires management to perform an assessment of going concern and provides specific guidance on when and how to assess or disclose going concern uncertainties. The new standard also defines terms used in the evaluation of going concern, such as "substantial doubt." Following its application, the Company will be required to perform assessments at each annual and interim period, provide an assessment period of one year from the issuance date, and make disclosures in certain circumstances in which substantial doubt is identified. The amendment will be effective for the Company for the first reporting period ending after December 15, 2016. Earlier application is permitted. The Company does not expect the adoption of this ASU to have an impact on its financial position, result of operations, or disclosures. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This amendment requires that equity investments, except those accounted for under the equity method of accounting or which result in consolidation of the investee, be measured at fair value with changes in the fair value being recorded in net income. However, equity investments that do not have readily determinable fair values will be measured at cost less impairment, if any, plus the effect of changes resulting from observable price transactions in orderly transactions or for the identical or similar investment of the same issuer. The amendment also simplifies the impairment assessment of equity instruments that do not have readily determinable fair values, eliminates the requirement to disclose methods and assumptions used to estimate fair value of instruments measured at their amortized cost on the balance sheet, requires that the disclosed fair values of financial instruments represent "exit price," requires entities to separately present in other comprehensive income the portion of the total change in fair value of a liability resulting from instrument-specific credit risk when the FVO has been elected for that liability, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes, and clarifies that an entity should evaluate the need for a valuation allowance on its deferred tax asset related to its available-for-sale securities in combination with its other deferred tax assets. This amendment will be effective for the Company for the first reporting period beginning after December 15, 2017, with earlier adoption permitted by public entities on a limited basis. Adoption of the amendment must be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, except for amendments related to equity instruments that do not have readily determinable fair values which should be applied prospectively. The Company is in the process of evaluating the impacts of the adoption of this ASU. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The guidance in this update supersedes the current lease accounting guidance for both the lessees and lessors under ASC 840, Leases. The new guidance requires lessees to evaluate whether a lease is a finance lease using criteria that are similar to what lessees use today to determine whether they have a capital lease. Leases not classified as finance leases are classified as operating leases. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. The lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to today’s guidance for operating leases. The new guidance will require lessors to account for leases using an approach that is substantially similar to the existing guidance for sales-type, direct financing leases and operating leases. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2018, with earlier adoption permitted. Adoption of the amendment must be applied on a modified retrospective approach. The Company is in the process of evaluating the impacts of the adoption of this ASU. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. The new guidance clarifies that a change in the counterparties to a derivative contract, i.e., a novation, in and of itself, does not require the de-designation of a hedging relationship. An entity will, however, still need to evaluate whether it is probable that the counterparty will perform under the contract as part of its ongoing effectiveness assessment for hedge accounting. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. Adoption of the new guidance can be applied on a modified retrospective or prospective basis. The Company is in the process of evaluating the impacts of the adoption of this ASU. NOTE 2. RECENT ACCOUNTING DEVELOPMENTS (continued) Also in March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments . The new guidance clarifies that an exercise contingency does not need to be evaluated to determine whether it relates to interest rates and credit risk in an embedded derivative analysis of hybrid financial instruments. In other words, a contingent put or call option embedded in a debt instrument would be evaluated for possible separate accounting as a derivative instrument without regard to the nature of the exercise contingency. However, as required under existing guidance, companies will still need to evaluate other relevant embedded derivative guidance, such as whether the payoff from the contingent put or call option is adjusted based on changes in an index other than interest rates or credit risk, and whether the debt involves a substantial premium or discount. The new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. The new guidance is required to be adopted on a modified retrospective basis to all existing and future debt instruments. The Company is in the process of evaluating the impacts of the adoption of this ASU. Additionally, in March 2016, the FASB issued ASU 2016-07, Investments-Equity Method and Joint Ventures (Topic 323) . The new guidance eliminates the requirement to apply the equity method of accounting retrospectively when a reporting entity obtains significant influence over a previously held investment. Instead, the equity method of accounting should be applied prospectively from the date significant influence is obtained. Investors should add the cost of acquiring the additional interest in the investee (if any) to the current basis of their previously held interest. The new standard also provides specific guidance for available-for-sale securities that become eligible for the equity method of accounting. In those cases, any unrealized gain or loss recorded within accumulated other comprehensive income should be recognized in earnings at the date the investment initially qualifies for the use of the equity method of accounting. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. Adoption of the new guidance can be applied only a prospective basis for investments those qualify for the equity method of accounting after the effective date. The Company is in the process of evaluating the impacts of the adoption of this ASU. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) . The new guidance simplifies certain aspects related to income taxes, SCF, and forfeitures when accounting for share-based payment transactions. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. Certain of the amendments related to timing of the recognition of tax benefits and tax withholding requirements should be applied using a modified retrospective transition method. Amendments related to the presentation of the SCF should be applied retrospectively. All other provisions may be applied on a prospective or modified retrospective basis. The Company is in the process of evaluating the impacts of the adoption of this ASU.

Based on this evaluation, it is reasonably possible that the Company may elect to pursue other strategies relative to its investment securities portfolio. As of March 31, 2016 and December 31, 2015 , the Company had investment securities available-for-sale with an estimated fair value of $7.5 billion and $3.5 billion , respectively, pledged as collateral, which was comprised of the following: $4.3 billion and $2.9 billion , respectively, were pledged to secure public fund deposits; $2.7 billion and $117.6 million , respectively, were pledged at various independent parties ("Brokers") to secure repurchase agreements, support hedging relationships, and for recourse on loan sales; and $459.0 million and $395.8 million , respectively, were pledged to secure the Company's customer overnight sweep product. NOTE 3. INVESTMENT SECURITIES (continued) At March 31, 2016 and December 31, 2015 , the Company had $54.9 million and $65.1 million , respectively, of accrued interest related to investment securities which is included in the Accrued interest receivable line of the Company's Condensed Consolidated Balance Sheet . The Company's state and municipal bond portfolio primarily consists of general obligation bonds of states, cities, counties and school districts. In March 2016, the Company decided to sell a significant portion of the municipal bond portfolio to reduce non-high quality liquid assets (non-HQLA), reduce investments to coincide with lower deposit balances and take gains to help cover the early terminations charges taken on FHLB advances. Contractual Maturity of Debt Securities Contractual maturities of the Company’s debt securities available-for-sale at March 31, 2016 are as follows: Amortized Cost Fair Value (in thousands) Due within one year $ 545,999 $ 547,001 Due after 1 year but within 5 years 3,073,546 3,094,514 Due after 5 years but within 10 years 318,364 320,688 Due after 10 years 16,491,393 16,560,226 Total $ 20,429,302 $ 20,522,429 Actual maturities may differ from contractual maturities when there is a right to call or prepay obligations with or without call or prepayment penalties.

Individual securities are further assessed for OTTI as deemed necessary. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. The OTTI assessment is a subjective process requiring the use of judgments and assumptions. During the securities-level assessments, consideration is given to (1) the intent not to sell and probability that the Company will not be required to sell the security before recovery of its cost basis to allow for any anticipated recovery in fair value, (2) the financial condition and near-term prospects of the issuer, as well as company news and current events, and (3) the ability to collect the future expected cash flows. Key assumptions utilized to forecast expected cash flows may include loss severity, expected cumulative loss percentage, cumulative loss percentage to date, weighted average Fair Isaac Corporation ("FICO ® ") scores and weighted average loan-to-value ("LTV") ratio, rating or scoring, credit ratings and market spreads, as applicable. The Company assesses and recognizes OTTI in accordance with applicable accounting standards. Under these standards, if the Company determines that impairment on its debt securities exists and it has made the decision to sell the security or it is more likely than not that the Company will be required to sell the security prior to recovery of its amortized cost basis, it recognizes the entire portion of the unrealized loss in earnings. If the Company has not made a decision to sell the security and it does not expect that it will be required to sell the security prior to the recovery of the amortized cost basis but the Company has determined that OTTI exists, it recognizes the credit-related portion of the decline in value of the security in earnings. The Company did not record any material OTTI in earnings related to its investment securities in the three-month periods ended March 31, 2016 or March 31, 2015 . Management has concluded that the unrealized losses on its debt and equity securities for which it has not recognized OTTI (which were comprised of 230 individual securities at March 31, 2016 ) are temporary in nature 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. Accordingly, the Company has concluded that the impairment on these securities is not other-than-temporary. NOTE 3. INVESTMENT SECURITIES (continued) Gains (Losses) and Proceeds on Sales of Securities Proceeds from sales of investment securities and the realized gross gains and losses from those sales are as follows: Three-Month Period 2016 2015 (in thousands) Proceeds from the sales of available-for-sale securities $ 3,435,844 $ 1,010,515 Gross realized gains $ 26,707 $ 10,782 Gross realized losses (276 ) (1,225 ) OTTI (10 ) — Net realized gains $ 26,421 $ 9,557 The Company uses the specific identification method to determine the cost of the securities sold and the gain or loss recognized. The Company recognized $26.4 million and $9.6 million for the three-month periods ended March 31, 2016 and March 31, 2015 , respectively, in net gains on sale of investment securities as a result of overall balance sheet and interest rate risk management. The net gain realized for the three-month period ended March 31, 2016 was primarily comprised of the sale of state and municipal securities with a book value of $726.8 million for a gain of $19.5 million and the sale of U.S. Treasury securities with a book value of $2.8 billion for a gain of $6.7 million . The net gain realized for the three-month period ended March 31, 2015 was primarily comprised of the sale of state and municipal securities with a book value of $305.4 million for a gain of $9.2 million . Other Investments Other investments primarily includes the Company's investment in the stock of the FHLB of Pittsburgh and the Federal Reserve Bank (the "FRB") with aggregate carrying amounts of $952.6 million and $997.9 million as of March 31, 2016 and December 31, 2015 , respectively. The stocks do not have readily determinable fair values because their ownership is restricted and they lack a market. The stocks can be sold back only at their par value of $100 per share and only to FHLBs or to another member institution. Accordingly, these stocks are carried at cost. During the three-month period ended March 31, 2016 , the Company purchased $74.9 million of FHLB stock at par, and redeemed $120.2 million of FHLB stock at par. There was no gain or loss associated with these redemptions. Other investments also includes $25.9 million and $26.4 million of low income housing tax credit ("LIHTC") investments as of March 31, 2016 and December 31, 2015 , respectively. The Company evaluates these investments for impairment based on the ultimate recoverability of the carrying value, rather than by recognizing temporary declines in value.

LOANS AND ALLOWANCE FOR CREDIT LOSSES	=640 3,185,795 11.9 % 3,018,902 11.8 % Total $ 26,849,278 100.0 % $ 25,669,232 100.0 % (1) Consists primarily of loans for which credit scores are not considered in the ALLL model. (2) Credit scores updated quarterly. (3) RICs and auto loans include $1.3 billion and $905.7 million of LHFS at March 31, 2016 and December 31, 2015 that do not have an allowance. Consumer Lending Asset Quality Indicators-FICO ® and Loan-to-Value ("LTV") For both residential and home equity loans, loss severity assumptions are incorporated in the loan and lease loss reserve models to estimate loan balances that will ultimately charge-off. These assumptions are based on recent loss experience within various current LTV bands within these portfolios. LTVs are refreshed quarterly by applying Federal Housing Finance Agency Home Price Index changes at a state-by-state level to the last known appraised value of the property to estimate the current LTV. The Company's ALLL incorporates the refreshed LTV information to update the distribution of defaulted loans by LTV as well as the associated loss given default for each LTV band. Reappraisals on a recurring basis at the individual property level are not considered cost-effective or necessary; however, reappraisals are performed on certain higher risk accounts to support line management activities, default servicing decisions, or when other situations arise for which the Company believes the additional expense is warranted.

TDR Loans The following table summarizes the Company’s performing and non-performing TDRs at the dates indicated: March 31, 2016 December 31, 2015 (in thousands) Performing $ 4,192,307 $ 3,807,751 Non-performing 510,677 603,496 Total $ 4,702,984 $ 4,411,247 Commercial Loan TDRs All of the Company’s commercial loan modifications are based on the circumstances of the individual customer, including specific customers' complete relationships with the Company. Loan terms are modified to meet each borrower’s specific circumstances at a point in time and may allow for modifications such as term extensions, interest rate reductions, etc. Modifications for commercial loan TDRs generally, although not always, result in bifurcation of the original loan into A and B notes. The A note is restructured to allow for upgraded risk rating and return to accrual status after a sustained period of payment performance has been achieved (typically six months for monthly payment schedules). The B note, if any, is structured as a deficiency note; the balance is charged off but the debt is usually not forgiven. Commercial TDRs are generally placed on non-accrual status until the Company believes repayment under the revised terms is reasonably assured and a sustained period of repayment performance has been achieved (typically six months for a monthly amortizing loan). As TDRs, they will be subject to analysis for specific reserves by either calculating the present value " id="sjs-B4" xml:space="preserve"> LOANS AND ALLOWANCE FOR CREDIT LOSSES Overall The Company's loans are reported at their outstanding principal balances net of any unearned income, cumulative charge-offs, unamortized deferred fees and costs on originated loans and unamortized premiums or discounts on purchased loans. The Company maintains an ACL to provide for losses inherent in its portfolios. Certain loans are pledged as collateral for borrowings, securitizations, or special purpose entities ("SPEs"). These loans totaled $54.7 billion at March 31, 2016 and $59.4 billion at December 31, 2015 . NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Loans that the Company intends to sell are classified as loans held-for-sale ("LHFS"). The LHFS portfolio balance at March 31, 2016 was $2.5 billion , compared to $3.2 billion at December 31, 2015 . LHFS in the residential mortgage portfolio are reported at fair value. All other LHFS are accounted for at the lower of cost or fair value. For a discussion on the valuation of LHFS at fair value, see Note 16 to the Condensed Consolidated Financial Statements . During the third quarter of 2015, the Company determined that it no longer intended to hold certain personal lending assets at SC for investment. The Company adjusted the ACL associated with SC's personal loan portfolio to value the portfolio at the lower of cost or market, and the adjusted credit loss allowance was released through the provision for credit losses; reflected as a charge-off against the credit loss allowance. Future loan originations and purchases under SC’s personal lending platform will also be classified as held for sale. As of March 31, 2016 , the value of the personal unsecured held-for-sale portfolio was $1.0 billion . On February 1, 2016 , SC completed the sale of assets from the personal unsecured held-for-sale portfolio to a third party for an immaterial gain to unpaid principal balance. The balance of the loans associated with this sale was $869.4 million . Interest income on loans is accrued based on the contractual interest rate and the principal amount outstanding, except for those loans classified as non-accrual. At March 31, 2016 and December 31, 2015 , accrued interest receivable on the Company's loans was $501.5 million and $531.2 million , respectively.

NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Portfolio segments and classes GAAP requires that entities disclose information about the credit quality of their financing receivables at disaggregated levels, specifically defined as “portfolio segments” and “classes,” based on management’s systematic methodology for determining the ACL. The Company utilizes an alternate 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 three commercial real estate lines of business distinctions include “Corporate banking,” which includes commercial and industrial owner-occupied real estate, “Middle market real estate,” which represents the portfolio of specialized lending for investment real estate, including financing for continuing care retirement communities and “Santander real estate capital”, which is the commercial real estate portfolio of the specialized lending group. "Commercial and industrial" includes non-real estate-related commercial and industrial loans. "Multifamily" represents loans for multifamily residential housing units. “Other commercial” primarily represents the CEVF business. The following table reconciles the Company's recorded investment classified by its major portfolio classifications to its commercial loan classifications utilized in its determination of the allowance for loan and lease losses ("ALLL") and other credit quality disclosures at March 31, 2016 and December 31, 2015 , respectively: Commercial Portfolio Segment (2) Major Loan Classifications (1) March 31, 2016 December 31, 2015 (in thousands) Commercial loans held for investment: Commercial real estate: Corporate Banking $ 2,959,176 $ 2,949,089 Middle Market Real Estate 4,855,085 4,223,359 Santander Real Estate Capital 1,501,030 1,550,469 Total commercial real estate 9,315,291 8,722,917 Commercial and industrial (3) 20,334,247 19,785,446 Multifamily 9,330,482 9,438,463 Other commercial 2,739,515 2,676,506 Total commercial loans held-for-investment $ 41,719,535 $ 40,623,332 (1) These represent the Company's loan categories based on the Securities and Exchange Commission (the "SEC's") Regulation S-X, Article 9. (2) These represent the Company's loan classes used to determine its ALLL. (3) Commercial and industrial loans had no LHFS at March 31, 2016 and excluded $86.4 million of LHFS at December 31, 2015 . The Company's portfolio segments are substantially the same as its financial statement categorization of loans for the 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. "RIC 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. NOTE 4.

NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Commercial Lending Asset Quality Indicators Commercial credit quality disaggregated by class of financing receivables is summarized according to standard regulatory classifications as follows: PASS. Asset is well-protected by the current net worth and paying capacity of the obligor or guarantors, if any, or by the fair value less costs to 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.

NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Consumer Lending Asset Quality Indicators-Credit Score In early 2015 , the Company increased its origination volume of RICs to borrowers with limited credit bureau attributes, such as less than 36 months of history or less than four trade lines. For these borrowers, many of whom do not have a FICO ® score, other factors, such as the LexisNexis risk view score, LTV ratio, and payment-to-income ratio, are utilized to assign an internal credit score. Origination volume of these RICs was $944.0 million for the three-month period ended March 31, 2016 . The Company's credit loss allowance forecasting models are not calibrated for this higher concentration of RICs with limited bureau attributes and, accordingly, as of March 31, 2016 , the Company recorded a qualitative adjustment of $193.3 million , increasing the allowance ratio on individually acquired RICs by 0.7% of unpaid principal balance. This adjustment was necessary to increase the ACL for additional charge-offs expected on this portfolio, based on loss performance information available to date, which evidences higher losses in the first months after origination for these RICs in comparison to RICs with standard credit bureau attributes. Consumer financing receivables for which either an internal or external credit score is a core component of the allowance model are summarized by credit score as follows: March 31, 2016 December 31, 2015 Credit Score Range (2) Retail installment contracts and auto loans (3) Percent Retail installment contracts and auto loans (3) Percent (dollars in thousands) No FICO ®(1) $ 4,676,147 17.4 % $ 4,932,840 19.2 % <600 14,425,278 53.7 % 13,436,588 52.3 % 600-639 4,562,058 17.0 % 4,280,902 16.7 % >=640 3,185,795 11.9 % 3,018,902 11.8 % Total $ 26,849,278 100.0 % $ 25,669,232 100.0 % (1) Consists primarily of loans for which credit scores are not considered in the ALLL model. (2) Credit scores updated quarterly. (3) RICs and auto loans include $1.3 billion and $905.7 million of LHFS at March 31, 2016 and December 31, 2015 that do not have an allowance. Consumer Lending Asset Quality Indicators-FICO ® and Loan-to-Value ("LTV") For both residential and home equity loans, loss severity assumptions are incorporated in the loan and lease loss reserve models to estimate loan balances that will ultimately charge-off. These assumptions are based on recent loss experience within various current LTV bands within these portfolios. LTVs are refreshed quarterly by applying Federal Housing Finance Agency Home Price Index changes at a state-by-state level to the last known appraised value of the property to estimate the current LTV. The Company's ALLL incorporates the refreshed LTV information to update the distribution of defaulted loans by LTV as well as the associated loss given default for each LTV band. Reappraisals on a recurring basis at the individual property level are not considered cost-effective or necessary; however, reappraisals are performed on certain higher risk accounts to support line management activities, default servicing decisions, or when other situations arise for which the Company believes the additional expense is warranted.

Loan terms are modified to meet each borrower’s specific circumstances at a point in time and may allow for modifications such as term extensions, interest rate reductions, etc. Modifications for commercial loan TDRs generally, although not always, result in bifurcation of the original loan into A and B notes. The A note is restructured to allow for upgraded risk rating and return to accrual status after a sustained period of payment performance has been achieved (typically six months for monthly payment schedules). The B note, if any, is structured as a deficiency note; the balance is charged off but the debt is usually not forgiven. Commercial TDRs are generally placed on non-accrual status until the Company believes repayment under the revised terms is reasonably assured and a sustained period of repayment performance has been achieved (typically six months for a monthly amortizing loan). As TDRs, they will be subject to analysis for specific reserves by either calculating the present value

Leases [Abstract]
LEASED VEHICLES, NET	LEASED VEHICLES, NET The Company has operating leases which are included in the Company's Condensed Consolidated Balance Sheets as Leased vehicles, net. The leased vehicle portfolio consists primarily of leases originated under a ten -year private label financing agreement signed by the Company with Fiat Chrysler Automobiles US LLC ("FCA"), formerly Chrysler Group LLC, to be a preferred lender (the "Chrysler Agreement"). Under the Chrysler Agreement, the Company had the first right to review and approve all prime Chrysler Capital consumer vehicle lease applications. SC provides servicing on all leases originated under this agreement. Leased vehicles, net consisted of the following as of March 31, 2016 and December 31, 2015 : March 31, 2016 December 31, 2015 (in thousands) Leased vehicles $ 12,284,996 $ 11,332,226 Origination fees and other costs 30,127 29,798 Manufacturer subvention payments, net of accretion (1,153,958 ) (1,061,501 ) Leased vehicles, gross 11,161,165 10,300,523 Less: accumulated depreciation (2,180,635 ) (1,911,693 ) Leased vehicles, net $ 8,980,530 $ 8,388,830 During the first quarter of 2016 , the Company did not execute any bulk sales of leases originated under the Chrysler Capital program ("Chrysler Capital"), the trade name used in providing services under the Chrysler Agreement. During the first quarter of 2015 , the Company executed a bulk sale of leases originated under the Chrysler Capital program with depreciated net capitalized costs of $561.3 million and a net book value of $488.9 million to a third party. The bulk sales agreement included certain provisions under which SC agreed to share in residual losses for lease terminations with losses over a specific percentage threshold. SC retained servicing on the leases sold. Due to the accelerated depreciation permitted for tax purposes, this sale generated large taxable gain that SC deferred through a qualified like-kind exchange program. An immaterial amount of taxable gain that did not qualify for deferral was recognized upon expiration of the reinvestment period. The following summarizes the future minimum rental payments due to the Company as lessor under operating leases as of March 31, 2016 (in thousands): Remainder of 2016 $ 1,192,976 2017 1,138,541 2018 444,767 2019 24,173 2020 50 Total $ 2,800,507 Lease income and expense for the three-month period ended March 31, 2016 were $434.7 million and $293.8 million , respectively, compared to $312.3 million and $235.9 million , respectively, for the three-month period ended March 31, 2015 .

VARIABLE INTEREST ENTITIES

VARIABLE INTEREST ENTITIES	3 Months Ended

Variable Interest Entity and Securitizations [Abstract]
VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES VIEs The Company transfers RICs and leases into newly-formed securitization trusts ("Trusts") that then issue one or more classes of notes payable backed by collateral. The Company’s continuing involvement with the Trusts is in the form of servicing assets held by the Trusts and, generally, through holding residual interests in the Trusts. These transactions are structured without recourse. The Trusts are considered VIEs under GAAP and, when the Company holds the residual interest, are consolidated because the Company has: (a) power over the significant activities of the entity as servicer of its financial assets and (b) residual interest and, in some cases of debt securities held by the Company, an obligation to absorb losses or the right to receive benefits from the VIE which are potentially significant to the VIE. When the Company does not retain any debt or equity interests in its securitizations or subsequently sells such interests it records these transactions as sales of the associated RIC. Revolving credit facilities generally also utilize Trusts that are considered VIEs. The collateral, borrowings under credit facilities and securitization notes payable of the Company's consolidated VIEs remain on the Company's Condensed Consolidated Balance Sheets . The Company recognizes finance charges and fee income on the RICs and leased vehicles and interest expense on the debt, and records a provision for loan and lease losses to cover probable inherent losses on the contracts. All of the Trusts are separate legal entities and the collateral and other assets held by these subsidiaries are owned by them and not available to other creditors. The Company also uses a titling trust to originate and hold its leased vehicles and the associated leases in order to facilitate the pledging of leases to financing facilities or the sale of leases to other parties without incurring the costs and administrative burden of retitling the lease vehicles. This titling trust is considered a VIE. On-balance sheet VIEs The following table summarizes the assets and liabilities related to the above mentioned VIEs that are included in the Company's Condensed Consolidated Financial Statements as of the date indicated: March 31, 2016 December 31, 2015 (in thousands) Restricted cash $ 1,982,611 $ 1,842,877 Loans (1) 23,577,939 23,726,979 Leased vehicles, net 7,298,521 6,516,030 Various other assets 581,758 620,482 Notes payable 30,515,797 30,628,837 Various other liabilities 7,654 5,379 (1) Includes $1.3 billion and $1.5 billion of RICs held for sale at March 31, 2016 and December 31, 2015 , respectively. The Company retains servicing responsibility 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. As of March 31, 2016 and December 31, 2015 , the Company was servicing $27.9 billion and $ 27.3 billion , respectively, of RICs that have been transferred to consolidated Trusts. The remainder of the Company’s RICs remains unpledged. NOTE 6. VARIABLE INTEREST ENTITIES (continued) Below is a summary of the cash flows received from the Trusts for the period indicated: Three-Month Period 2016 2015 (in thousands) Assets securitized $ 3,621,496 $ 3,981,855 Net proceeds from new securitizations (1) 2,633,626 3,060,862 Cash received for servicing fees (2) 194,365 159,802 Net distributions from Trusts (2) 431,591 300,487 Total cash received from securitization trusts $ 3,259,582 $ 3,521,151 (1) Includes additional advances on existing securitizations. (2) These amounts are not reflected in the accompanying Condensed Consolidated Statements of Cash Flows because the cash flows are between the VIEs and other entities included in the consolidation. Off-balance sheet VIEs The Company has completed sales to VIEs that met sale accounting treatment in accordance with the applicable guidance. Due to the nature, purpose, and activity of these transactions, the Company determined for consolidation purposes that it either does not hold potentially significant variable interests or is not the primary beneficiary as a result of the Company's limited further involvement with the financial assets. For such transactions, the transferred financial assets are removed from the Company's Condensed Consolidated Balance Sheets . In certain situations, the Company remains the servicer of the financial assets and receives servicing fees that represent adequate compensation, and may reacquire assets from the Trusts through the exercise of an optional clean-up call, as permitted through the respective servicing agreements. The Company also recognizes a gain or loss in the amount of the difference between the cash proceeds and carrying value of the assets sold. During the three-month period ended March 31, 2016 , the Company executed no off-balance sheet securitizations with VIEs in which it has continuing involvement. As of March 31, 2016 and December 31, 2015 , the Company was servicing $3.4 billion and $3.9 billion , respectively, of gross RICs in off-balance sheet securitizations. Other than repurchases of sold assets due to standard representations and warranties, the Company has no exposure to loss as a result of its involvement with these VIEs. A summary of the cash flows received from the off-balance sheet Trusts for the periods indicated is as follows: Three-Month Period 2016 2015 (in thousands) Assets securitized $ — $ — Net proceeds from new securitizations $ — $ — Cash received for servicing fees 15,701 5,304 Total cash received from securitization trusts $ 15,701 $ 5,304

(2) Commercial Real Estate and Commercial Banking were formerly disclosed as the combined Real Estate and Commercial Banking segment. As more fully described in Note 17 to the Condensed Consolidated Financial Statements , during the first quarter of 2016, certain management and line of business changes became effective as the Company reorganized its management reporting in order to improve its structure and focus to better align management teams and resources with the business goals of the Company and provide enhanced customer service to its clients. Accordingly, the following changes were made within the Company's reportable segments and reporting units to provide greater focus on each of its core businesses: • The small business banking, commercial business banking, and auto leasing lines of business formerly included in the Auto Finance and Business Banking reportable segment were combined with the Consumer and Business Banking reportable segment. The combined impact of these organizational changes resulted in the re-allocation of $330.0 million of goodwill from Auto Finance & Business Banking to Consumer and Business Banking. • The Real Estate and Commercial Banking reportable segment was split into the Commercial Real Estate reportable segment and the Commercial Banking reportable segment, resulting in the re-allocation of $870.4 million of goodwill from Commercial Banking to Commercial Real Estate. • The commercial equipment vehicle financing and dealer floor plan lines of business, formerly included in the Auto Finance & Business Banking reportable segment were moved to the Commercial Banking business unit, resulting in the re-allocation of $115.9 million of goodwill from Auto Finance & Business Banking to Commercial Banking. NOTE 7. GOODWILL AND OTHER INTANGIBLES (continued) Previously, the Company reorganized its management reporting in the third quarter of 2015 in order to improve its structure and focus by better aligning management teams and resources with the business goals of the Company and to provide enhanced customer service to its clients. As a result of the change in segment reporting, the Company re-evaluated its conclusions related to goodwill reporting units, including the following: • The small business banking business unit, formerly included in the Retail Banking reportable segment, was combined with the Auto Finance and Business Banking business unit, resulting in re-allocation of goodwill in the amount of $265.4 million from Retail Banking to Auto Finance and Business Banking. • The commercial business banking business unit, formerly included in the Real Estate and Commercial Banking reportable segment, was combined with the Auto Finance and Business Banking business unit resulting in the re-allocation of goodwill in the amount of $109.0 million from Real Estate and Commercial Banking to Auto Finance and Business Banking. The Company conducted its annual goodwill impairment test as of October 1, 2015 using generally accepted valuation methods. After conducting an analysis of the fair value of each reporting unit as of October 1, 2015 , the Company determined that there was no impairment of goodwill identified as a result of the annual impairment analysis. During the fourth quarter of 2015, due to a decline in SC's share price, the Company concluded that the fair value of our SC reporting unit was more likely than not less than its carrying value including goodwill. As a result, the Company performed an interim goodwill impairment analysis as of December 31, 2015 , the results of which required the Company to record an impairment of $4.4 billion . During the first quarter of 2016 , the Company continued to evaluate SC's share price.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES General The Company uses derivative financial instruments primarily to help manage exposure to interest rate, foreign exchange, equity and credit risk, as well as to reduce the effects that changes in interest rates may have on net income, the fair value of assets and liabilities, and cash flows. The Company also enters into derivatives with customers to facilitate their risk management activities. The Company uses derivative financial instruments as risk management tools and not for speculative trading purposes. The fair value of all derivative balances is recorded within Other assets and Other liabilities on the Condensed Consolidated Balance Sheet . See Note 16 for discussion of the valuation methodology for derivative instruments. Derivatives represent contracts between parties that usually require little or no initial net investment and result in one party delivering cash or another type of asset to the other party based on a notional amount and an underlying as specified in the contract. Derivative transactions are often measured in terms of notional amount, but this amount is generally not exchanged and is not recorded on the balance sheet. The notional amount is the basis to which the underlying is applied to determine required payments under the derivative contract. The underlying is a referenced interest rate (commonly Overnight Indexed Swap rate ("OIS") or LIBOR), security price, credit spread or other index. Derivative balances are presented on a gross basis taking into consideration the effects of legally enforceable master netting agreements. 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. NOTE 11. DERIVATIVES (continued) Credit Risk Contingent Features The Company has entered into certain derivative contracts that require the posting of collateral to counterparties when these contracts are in a net liability position. The amount of collateral to be posted is based on the amount of the net liability and thresholds generally related to the Company's long-term senior unsecured credit ratings. In a limited number of instances, counterparties also have the right to terminate their International Swaps and Derivatives Association, Inc. ("ISDA") master agreements if the Company's ratings fall below investment grade. As of March 31, 2016 , derivatives in this category had a fair value of $1.0 million . The credit ratings of the Company and Bank are currently considered investment grade. The Company estimates as of March 31, 2016 that a further 1 - or 2 - notch downgrade by either Standard & Poor's ("S&P") or Moody's would require the Company to post up to an additional $2.8 million or $3.2 million of collateral, respectively, to comply with existing derivative agreements. As of March 31, 2016 and December 31, 2015 , 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 $126.3 million and $128.1 million , respectively. The Company had $127.6 million and $128.8 million in cash and securities collateral posted to cover those positions as of March 31, 2016 and December 31, 2015 , respectively. Fair Value Hedges The Company enters into cross-currency swaps to hedge its foreign currency exchange risk on certain Euro-denominated investments. The Company also entered into interest rate swaps to hedge the interest rate risk on certain fixed rate investments. These derivatives are designated as fair value hedges at inception. The Company includes all components of each derivative's gain or loss in the assessment of hedge effectiveness. The earnings impact of the ineffective portion of these hedges was not material for the three-month periods ended March 31, 2016 and 2015 . The last of the hedges is scheduled to expire in June 2020 . Cash Flow Hedges Management uses derivative instruments, which are designated as hedges, to mitigate the impact of interest rate movements on the fair value of certain liabilities, assets and on highly probable forecasted cash flows. These instruments primarily include interest rate swaps that have underlying interest rates based on key benchmark indices and forward sale or purchase commitments. 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. The last of the hedges is scheduled to expire in December 2030 . The Company includes all components of each derivative's gain or loss in the assessment of hedge effectiveness. The earnings impact of the ineffective portion of these hedges was not material for the three-month periods ended March 31, 2016 and 2015 . As of March 31, 2016 , the Company expects no gross losses recorded in accumulated other comprehensive loss to be reclassified to earnings during the subsequent twelve months as the future cash flows occur. NOTE 11. DERIVATIVES (continued) Derivatives Designated in Hedge Relationships – Notional and Fair Values Derivatives designated as accounting hedges at March 31, 2016 and December 31, 2015 included: Notional Amount Asset Liability Weighted Average Receive Rate Weighted Average Pay Rate Weighted Average Life (Years) (dollars in thousands) March 31, 2016 Fair value hedges: Interest rate swaps $ 351,000 $ 804 $ 7,247 1.38 % 2.22 % 3.22 Cash flow hedges: Pay fixed — receive floating interest rate swaps 11,926,299 189 94,576 0.46 % 1.12 % 2.92 Total $ 12,277,299 $ 993 $ 101,823 0.49 % 1.15 % 2.93 December 31, 2015 Fair Value hedges: Cross-currency swaps $ 16,390 $ 3,695 $ 92 4.76 % 4.75 % 0.11 Interest rate swaps 318,000 47 2,006 1.07 % 2.31 % 3.50 Cash flow hedges: Pay fixed — receive floating interest rate swaps 11,030,431 7,295 23,047 0.32 % 1.13 % 3.00 Total $ 11,364,821 $ 11,037 $ 25,145 0.35 % 1.17 % 3.01 See Note 13 for detail of the amounts included in accumulated other comprehensive income related to derivatives activity. Cross-currency swaps designated as hedges matured during the first quarter of 2016. 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 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 securitization 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 typically also carried at fair value on the balance sheet, resulting in generally symmetrical accounting treatment for the hedging instrument and the hedged item. Mortgage Banking Derivatives The Company's derivatives portfolio includes mortgage banking interest rate lock commitments, forward sale commitments and interest rate swaps. As part of its overall business strategy, the Company originates fixed-rate residential mortgages. It sells a portion of this production to the FHLMC, 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. NOTE 11. DERIVATIVES (continued) The Company typically retains the servicing rights related to residential mortgage loans that are sold. 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. 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. 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.

A master netting agreement allows two counterparties the ability to net-settle amounts under all contracts, including any related collateral posted, through a single payment and in a single currency. The right to offset and certain terms regarding the collateral process, such as valuation, credit events and settlement, are contained in the ISDA master agreement. The Company's financial instruments, including resell and repurchase agreements, securities lending arrangements, derivatives and cash collateral, may be eligible for offset on its Condensed Consolidated Balance Sheet . The Company has elected to present derivative balances on a gross basis even if the derivative is subject to a legally enforceable master netting ISDA agreements 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 Sheet ” 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 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 Sheet " section of the tables below.

INCOME TAXES

INCOME TAXES	3 Months Ended
	Mar. 31, 2016
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES An income tax provision of $65.0 million was recorded for the three-month period ended March 31, 2016 , compared to $40.1 million for the corresponding period in 2015 . This resulted in an effective tax rate of 46.9% for the three-month period ended March 31, 2016 , compared to 20.8% for the corresponding period in 2015 . The Company recognized a discrete income tax provision of $2.9 million for the three-month period ended March 31, 2016 and a discrete income tax benefit of $21.2 million for the three-month period ended March 31, 2015 , which resulted in the higher effective tax rate for the three-month period ended March 31, 2016 . NOTE 12. INCOME TAXES (continued) 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 the 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. The Company has a lawsuit pending against the United States in Federal District Court in Massachusetts relating to the proper tax consequences of two financing transactions with an international bank through which the Company borrowed $1.2 billion . As a result of these financing transactions, the Company paid foreign taxes of $264.0 million during the years 2003 through 2007 and claimed a corresponding foreign tax credit for foreign taxes paid during those years, which the Internal Revenue Service ("IRS") disallowed. The IRS also disallowed the Company's deductions for interest expense and transaction costs, totaling $74.6 million in tax liability, and assessed penalties and interest totaling approximately $92.5 million . The Company has paid the taxes, penalties and interest associated with the IRS adjustments for all tax years, and the lawsuit will determine whether the Company is entitled to a refund of the amounts paid. The Company has recorded a receivable in the Other assets line of the Condensed Consolidated Balance Sheets for the amount of these payments, less a tax reserve of $230.1 million , as of March 31, 2016 . On November 13, 2015, the Federal District Court issued a written opinion in favor of the Company on all contested issues, and in a judgment issued on January 13, 2016, ordered amounts assessed by the IRS for years 2003 through 2005 to be refunded to the Company. On March 11, 2016, the IRS filed a notice of appeal. The appeal will be heard in the First Circuit. In 2013, two different federal courts decided cases involving similar financing structures entered into by the Bank of New York Mellon Corp. ("BNY Mellon") and BB&T Corp. ("BB&T") in favor of the IRS. BNY Mellon and BB&T each appealed. On May 14, 2015, the Court of Appeals for the Federal Circuit decided BB&T's appeal by affirming the trial court's decision to disallow BB&T's foreign tax credits and to allow penalties, but reversed the trial court and allowed BB&T's entitlement to interest deductions. On September 9, 2015, the Court of Appeals for the Second Circuit upheld the trial court's decision in BNY Mellon's case, allowing BNY Mellon to claim interest deductions, but disallowing BNY Mellon's claimed foreign tax credits. On September 29, 2015, BB&T filed a petition requesting the U.S. Supreme Court to hear its appeal of the Federal Circuit Court’s decision. BNY Mellon filed a petition requesting the U.S. Supreme Court hear its appeal of the Second Circuit’s decision on November 3, 2015. On March 7, 2016, the U.S. Supreme Court denied BB&T's and BNY Mellon's petitions. The Company has not changed its reserve position as of March 31, 2016 , and remains confident in the legal merits of its position and believes its reserve amount adequately provides for potential exposure to the IRS related to these items. Over the next 12 months, it is reasonably possible that changes in the reserve for uncertain tax positions could range from a decrease of $230.1 million to an increase of $201.9 million . With few exceptions, the Company is no longer subject to federal, state and non-US income tax examinations by tax authorities for years prior to 2003.

COMMITMENTS, CONTINGENCIES AND

COMMITMENTS, CONTINGENCIES AND GUARANTEES	3 Months Ended
	Mar. 31, 2016
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES AND GUARANTEES	COMMITMENTS, CONTINGENCIES AND GUARANTEES Off-Balance Sheet Risk - Financial Instruments In the normal course of business, the Company utilizes a variety of financial instruments with off-balance sheet risk to meet the financing needs of its customers and manage its exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, letters of credit, loans sold with recourse, forward contracts, and interest rate and cross currency swaps, caps and floors. These financial instruments may involve, to varying degrees, elements of credit, liquidity, and interest rate risk in excess of the amount recognized on the Condensed Consolidated Balance Sheet . 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 11 to these Condensed Consolidated Financial Statements for discussion of all derivative contract commitments. NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) The following table details the amount of commitments at the dates indicated: Other Commitments March 31, 2016 December 31, 2015 (in thousands) Commitments to extend credit (1) $ 28,277,773 $ 31,379,039 Letters of credit 1,846,310 1,832,884 Recourse exposure on sold loans 73,286 70,394 Commitments to sell loans 53,237 56,982 Total commitments $ 30,250,606 $ 33,339,299 (1) Commitments to extend credit excludes commitments that can be canceled by the Company without notice. 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. During the quarter ended March 31, 2016 , SBNA transferred and settled $2.3 billion of unfunded commitments to extend credit to an unconsolidated related party for a loss on sale of $6.3 million . Subsequent to March 31, 2016 but prior to the issuance of the financial statements, SBNA transferred and settled an additional $1.3 billion of unfunded commitments to extend credit to an unconsolidated related party. The following table details the amount of commitments to extend credit expiring per period as of the dates indicated: March 31, 2016 December 31, 2015 (in thousands) 1 year or less $ 5,746,695 $ 6,451,239 Over 1 year to 3 years 4,981,342 5,250,512 Over 3 years to 5 years 9,920,170 12,136,625 Over 5 years (1) 7,629,566 7,540,663 Total $ 28,277,773 $ 31,379,039 (1) Includes certain commitments to extend credit that do not have a contractual maturity date, but are expected to be outstanding greater than 5 years . Unsecured Revolving Lines of Credit Such commitments, included in the Commitments to extend credit line above, 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 periodically reviewed based on account usage, customer creditworthiness and loan qualifications. NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) 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 is 15.0 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 March 31, 2016 was $1.8 billion . The fees related to letters of credit are deferred and amortized over the life of the respective commitments and were immaterial to the Company’s financial statements at March 31, 2016 . Management believes that the utilization rate of these letters of credit will continue to be substantially less than the amount of the commitments, as has been the Company’s experience to date. As of March 31, 2016 and December 31, 2015 , the liability related to these letters of credit was $22.2 million and $29.9 million , respectively, which is recorded within the reserve for unfunded lending commitments in Other liabilities on the Condensed Consolidated Balance Sheet . The credit risk associated with letters of credit is monitored using the same risk rating system utilized within the loan and financing lease portfolio. Also included within the reserve for unfunded lending commitments at March 31, 2016 and December 31, 2015 were lines of credit outstanding of $149.8 million and $117.5 million , respectively. The following table details the amount of letters of credit expiring per period as of the dates indicated: March 31, 2016 December 31, 2015 (in thousands) 1 year or less $ 1,215,499 $ 1,230,424 Over 1 year to 3 years 522,750 308,634 Over 3 years to 5 years 52,816 268,946 Over 5 years 55,245 24,880 Total $ 1,846,310 $ 1,832,884 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 FNMA, the Company retained a portion of the associated credit risk. The unpaid principal balance outstanding of loans sold in these programs was $543.7 million as of March 31, 2016 and $552.1 million as of December 31, 2015 . As a result of its agreement with FNMA, the Company retained a 100% first loss position on each multifamily loan sold to FNMA until the earlier to occur of (i) the aggregate approved losses on multifamily loans sold to FNMA reaching the maximum loss exposure for the portfolio as a whole of $34.4 million as of March 31, 2016 and $34.4 million as of December 31, 2015 , or (ii) the time when such loans sold to FNMA under this program are fully paid off. Any losses sustained as a result of impediments in standard representations and warranties would be in addition to the maximum loss exposure. The Company has established a liability which represents the fair value of the retained credit exposure and the amount the Company estimates it would have to pay a third party to assume the retained recourse obligation. The estimated liability is calculated as the present value of losses that the portfolio is projected to incur based upon internal specific information and an industry-based default curve with a range of estimated losses. At March 31, 2016 and December 31, 2015 , the Company had $6.4 million and $6.8 million , respectively, of reserves classified in Accrued expenses and payables on the Condensed Consolidated Balance Sheets related to the fair value of the retained credit exposure for loans sold to FNMA under this program. The Company's commitment will expire in March 2039 based on the maturity of the loans sold with recourse. Losses sustained by the Company may be offset, or partially offset, by proceeds resulting from the disposition of the underlying mortgaged properties. Approval from FNMA is required for all transactions related to the liquidation of properties underlying the mortgages. NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Commitments to Sell Loans The Company enters into forward contracts relating to its mortgage banking business to hedge the exposures from commitments to make new residential mortgage loans with existing customers and from mortgage loans classified as LHFS. These contracts mature in less than one year . SC Commitments SC is obligated to make purchase price hold-back payments to a third party originator of auto loans that it has purchased, when losses are lower than originally expected. SC is also obligated to make total return settlement payments to this third party originator beginning in June 2016 if returns on the purchased pools are greater than originally expected. SC had $56.8 million and $57.6 million accrued at March 31, 2016 and December 31, 2015 , respectively, related to this obligation. SC has extended revolving lines of credit to certain auto dealers. Under this arrangement, SC is committed to lend up to each dealer's established credit limit. At March 31, 2016 and December 31, 2015, there was an outstanding balance of $26.0 million and $26.9 million , respectively and a committed amount of $28.5 million and $27.4 million , respectively. On February 1, 2016 , SC completed the sale of substantially all of its LendingClub loans to a third-party buyer at an immaterial premium to par value. The portfolio comprised personal installment loans with an unpaid principal balance of approximately $869.4 million as of the date of the sale. SC committed to purchase certain new advances on personal revolving financings originated by a third-party retailer, along with existing balances on accounts with new advances, for an initial term ending in April 2020 and renewing through April 2022 at the retailer's option. Each customer account generated under the agreements generally is approved with a credit limit higher than the amount of the initial purchase, with each subsequent purchase automatically approved as long as it does not cause the account to exceed its limit and the customer is in good standing. As these credit lines do not have a specified maturity, but rather can be terminated at any time in the event of adverse credit changes or lack of use, SC has not recorded an allowance for unfunded commitments. As of March 31, 2016 and December 31, 2015 , SC was obligated to purchase $11.6 million and $12.5 million , respectively, in receivables that had been originated by the retailer but not yet purchased by SC. SC is also required to make a profit-sharing payment to the retailer each month if performance exceeds a specified return threshold. The retailer also has the right to repurchase up to 9.99% of the existing portfolio at any time during the term of the agreement, and, provided that repurchase right is exercised, has the right to retain up to 20% of new accounts subsequently originated. Under terms of an application transfer agreement with an original equipment manufacturer (OEM), SC has the first opportunity to review for its own portfolio any credit applications turned down by the OEM's captive finance company. The agreement does not require SC to originate any loans, but for each loan originated SC pays the OEM a referral fee, comprised of a volume bonus fee and a loss betterment bonus fee. The loss betterment bonus fee is calculated annually and is based on the amount by which losses on loans originated under the agreement are lower than an established percentage threshold. In connection with the sale of RICs through securitizations and other sales, SC has made standard representations and warranties customary in the consumer finance industry. Breaches 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 March 31, 2016 , SC had no loans that were the subject of a demand to repurchase or replace for breach of representations and warranties for SC's asset-backed securities or other sales. In the opinion of management, the potential exposure of other recourse obligations related to SC’s retail installment contract sales agreements will not have a material adverse effect on SC’s 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. NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Under terms of the Chrysler Agreement, SC must make revenue-sharing payments to FCA and also must make gain-sharing payments when residual gains on leased vehicles exceed a specified threshold. SC had accrued $10.7 million and $12.1 million at March 31, 2016 and December 31, 2015 , respectively, related to this obligation. SC has a flow agreement with Bank of America whereby SC is committed to sell up to a specified amount of eligible loans to Bank of America each month through May 2018 . Prior to October 1, 2015, the amount of this monthly commitment was $300.0 million . On October 1, 2015 , SC and Bank of America amended the flow agreement to increase the maximum commitment to sell to $350.0 million of eligible loans each month, and to change the required written notice period from either party, in the event of termination of the agreement, from 120 days to 90 days. 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 time of sale. SC had accrued $8.0 million and $6.3 million at March 31, 2016 and December 31, 2015 , respectively, related to this obligation. SC has sold loans to Citizens Bank of Pennsylvania ("CBP") under terms of a flow agreement and predecessor sale agreements. SC retains servicing on the sold loans and will owe 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. On June 25, 2015 , SC executed an amendment to the servicing agreement with CBP, which increased the servicing fee SC receives. SC and CBP also amended the flow agreement, which reduced, effective from and after August 1, 2015 , CBP's committed purchases of Chrysler Capital prime loans from a maximum of $600.0 million and a minimum of $250.0 million per quarter to a maximum of $200.0 million and a minimum of $50.0 million per quarter, as may be adjusted according to the agreement. In January 2016, the Company executed an amendment to the servicing agreement with CBP that decreased the servicing fee the Company receives on loans sold to CBP by the Company under the flow agreement. SC had accrued $3.4 million at March 31, 2016 and December 31, 2015 related to the loss-sharing obligation. As of March 31, 2016 , SC is party to a forward flow asset sale agreement with a third party under the terms of which SC is committed to sell charged-off loan receivables in bankruptcy status on a quarterly basis until sales total at least $350.0 million in proceeds. Any sale after the total sales have reached $275.0 million is subject to a market price check. As of March 31, 2016 and December 31, 2015 , the remaining aggregate commitment was $195.7 million and $200.7 million , respectively. In connection with the bulk sales of Chrysler Capital leases to a third party, SC is obligated to make quarterly payments to the purchaser sharing residual losses for lease terminations with losses over a specific percentage threshold. The estimated guarantee liability was $1.9 million and $2.9 million , net, as of March 31, 2016 and December 31, 2015 , 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. Litigation In the ordinary course of business, the Company and its subsidiaries are parties to pending and threatened legal actions and proceedings, including class action claims. These actions and proceedings are generally based on alleged violations of consumer protection, securities, environmental, banking, employment and other laws. In some of these actions and proceedings, claims for substantial monetary damages are asserted against the Company and/or its subsidiaries. In the ordinary course of business, the Company and its subsidiaries also are subject to regulatory examinations, inspections, information-gathering requests, inquiries and investigations, including by the Board of Governors of the Federal Reserve System (the “Federal Reserve”), the Office of the Comptroller of the Currency (the “OCC”), the Consumer Financial Protection Bureau (the “CFPB”), the Federal Deposit Insurance Corporation (the “FDIC”), the Department of Justice (the “DOJ”), the SEC, state attorneys general, and other state and federal governmental and regulatory authorities. NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) In view of the inherent difficulty of predicting the outcome of such litigation and regulatory matters, 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 losses, fines or penalties, if any, related to the respective matters. The Company does not presently anticipate that the ultimate aggregate liability, if any, arising out of such other legal proceedings will have a material effect on its financial position. In accordance with applicable accounting guidance, the Company establishes an accrued liability for litigation and regulatory matters when those matters present loss contingencies that are both probable and estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. When a loss contingency is not both probable and estimable, the Company does not establish an accrued liability. As a litigation, enforcement, or regulatory matter develops, the Company, in conjunction with its counsel, including any outside counsel handling the matter, evaluates on an ongoing basis whether the matter presents a loss contingency that is probable and estimable, during which quarter an accrued liability is established or adjusted with respect to such loss contingency. The Company continues to monitor the matter for further developments that could affect the amount of the accrued liability previously established. For certain of the Company's legal matters, the Company is able to estimate a range of reasonably possible losses. For other matters for which some loss is probable or reasonably possible, such an estimate is not possible. Management currently estimates that it is reasonably possible that the Company could incur losses in an aggregate amount of up to approximately $12.0 million in excess of the accrued liability, if any, with it also being reasonably possible that the Company could incur no such losses in these matters. This estimated range of reasonably possible losses represents the estimate of possible losses over the life of such legal matters, which may span an indeterminable number of years, and is based on information available as of March 31, 2016 . The regulatory matters for which it is reasonably possible that the Company will incur a significant loss are described below. The Company may include in some of the descriptions of individual disclosed matters certain quantitative information related to the plaintiff's claim against the Company as alleged in the plaintiff's pleadings or other public filings or otherwise based on publicly available information. While information of this type may provide insight into the potential magnitude of a matter, it does not necessarily represent the Company's estimate of reasonably possible loss or its judgment as to any currently appropriate accrual. Refer to Note 12 to these Condensed Consolidated Financial Statements for disclosure regarding the lawsuit filed by the Company against the IRS/United States. Other Regulatory and Governmental Matters Foreclosure Matters On May 22, 2013 , the Bank received a subpoena from the U.S. Attorney's Office for the Southern District of New York seeking information regarding claims for foreclosure expenses incurred in connection with the foreclosure of loans insured or guaranteed by the Federal Housing Financing Agency, FNMA or FHLMC. The Bank is cooperating with the investigation; however, there can be no assurance that claims or litigation will not arise from this matter. On June 16, 2015, the Bank entered into a consent order with the OCC amending the consent order issued by the Office of Thrift Supervision (“OTS”) in 2011 (the "Order") as well as the 2013 amendment to the Order (the “2015 Amendment”). The 2015 Amendment provided that the Bank had not fully complied with the terms of the Order as amended and that nine actionable items remained. The 2015 Amendment imposed certain supervisory restrictions on the Bank’s mortgage origination and servicing business. These restrictions required the Bank to obtain prior supervisory nonobjection from the OCC before engaging in certain new or broader mortgage origination and servicing activities or appointing new senior mortgage servicing officers, although the Bank was able to generally operate its current mortgage origination and servicing business in the ordinary course. The 2015 Amendment confirmed that the Bank has fulfilled its obligations to pay $6.2 million into a remediation fund and to engage in foreclosure avoidance activities in an aggregate principal amount of at least $9.9 million , both of which were required by the 2013 amendment to the Order executed by the Bank in February of 2013 that ended the independent file review required by the Order. NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) The Bank addressed the nine actionable items delineated in the 2015 Amendment and on February 8, 2016, the OCC terminated the Order in its entirety and assessed a civil monetary penalty of $3.4 million , which has been paid by the Bank. Identity Theft Protection Product Matter The Bank had been in discussions to address concerns that some customers may have paid for but did not receive certain benefits of an identity theft protection product from the Bank's third-party vendor. In response to those concerns, as of December 31, 2014 , the Bank had made $37.6 million in total remediation payments to customers. Notwithstanding those payments, on March 26, 2015, the Bank received a Consent Cease and Desist Order ("Consent Order") from the OCC regarding identified deficiencies in SBNA's billing practices with regard to an identity protection product. Pursuant to the Consent Order, the Bank paid a civil monetary penalty of $6.0 million and agreed to remediate customers who paid for but may not have received certain benefits of the identity theft protection product. As indicated above, as of the end of 2014, all customers had been mailed a refund representing the amount paid for product enrollment. Subsequently, the Bank commenced a further review in order to remediate checking account customers who may have been charged an overdraft fee and credit card customers who may have been charged an over limit fee and/or finance charge related to the identity theft protection product fees. The amount of additional remediation paid by the Bank related to these charges was approximately $5.2 million . In response to the Consent Order, the Bank presented Reimbursement and Action Plans which received non-objection from the OCC on December 21, 2015. Since that time, the actions set forth in the Plans are underway as is ongoing reporting to the OCC. We continue to make progress in addressing these requirements, but the Consent Order remains in place and we are unable to predict when it may be terminated. Marketing of Overdraft Coverage On April 1, 2014 , the Bank received a civil investigative demand (“CID”) from the CFPB requesting information and documents in connection with the Bank’s marketing to consumers of overdraft coverage for automated teller machine ("ATM") and/or onetime debit card transactions. The bank received a second CFPB CID related to the same overdraft coverage program on February 10, 2015 . Pursuant to the terms of the CIDs, the information obtained by the CFPB will be used to determine whether the Bank is in compliance with laws administered by the CFPB. The Bank is cooperating with the investigation; however, there can be no assurance that claims or litigation will not arise from this matter. The Company's practice is to cooperate fully with regulatory and governmental investigations, audits and other inquiries, including those described above. SC matters Periodically, SC is party to or otherwise involved in various lawsuits and other legal proceedings that arise in the ordinary course of business. On August 26, 2014 , a purported securities class action lawsuit was filed in the United States District Court, Southern District of New York, captioned Steck v. Santander Consumer USA Holdings Inc. et al., No. 1:14-cv-06942 (the "Deka Lawsuit"). On October 6, 2014 , another purported securities class action lawsuit was filed in the District Court of Dallas County, State of Texas, captioned Kumar v. Santander Consumer USA Holdings, et al., No. DC-14-11783, which was subsequently removed to the United States District Court, Northern District of Texas and re-captioned Kumar v. Santander Consumer USA Holdings, et al., No. 3:14-CV-3746 (the "Kumar Lawsuit"). NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) Both the Deka Lawsuit and the Kumar Lawsuit were brought against SC, certain of its current and former directors and executive officers and certain institutions that served as underwriters in SC's IPO on behalf of a class consisting of those who purchased or otherwise acquired securities between January 23, 2014 and June 12, 2014. In February 2015, the Kumar Lawsuit was voluntarily dismissed with prejudice. In June 2015, the venue of the Deka Lawsuit was transferred to the United States District Court, Northern District of Texas. In September 2015, the court granted a motion to appoint lead plaintiffs and lead counsel, and the Deka Lawsuit is now captioned Deka Investment GmbH et al. v. Santander Consumer USA Holdings Inc. et al., No. 3:15-cv-2129-K. The amended class action complaint in the Deka Lawsuit alleges that that SC's registration statement and prospectus and certain subsequent public disclosures contained misleading statements concerning SC’s ability to pay dividends and the adequacy of SC’s compliance systems and oversight. The amended complaint asserts claims under Sections 11, 12(a) and 15 of the Securities Act of 1933 and under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 10b-5 promulgated thereunder, and seeks damages and other relief. On December 18, 2015, SC and the individual defendants moved to dismiss the amended class action complaint. On October 15, 2015 , a shareholder derivative complaint was filed in the Court of Chancery of the State of Delaware, captioned Feldman v. Jason A. Kulas, et al., C.A. No. 11614 (the "Feldman Lawsuit"). The Feldman Lawsuit names as defendants current and former members of SC’s Board, and names SC as a nominal defendant. The complaint alleges, among other things, that the current and former director defendants breached their fiduciary duties in connection with overseeing SC’s subprime auto lending practices, resulting in harm to SC. The complaint seeks unspecified damages and equitable relief. On December 29, 2015, the Feldman Lawsuit was stayed pending the resolution of the Deka Lawsuit. On March 18, 2016, a purported securities class action lawsuit was filed in the United States District Court, Northern District of Texas, captioned Parmelee v. Santander Consumer USA Holdings Inc. et al., No. 3:16-cv-783 (the "Parmelee Lawsuit"). On April 4, 2016, another purported securities class action lawsuit was filed in the United States District Court, Northern District of Texas, captioned Benson v. Santander Consumer USA Holdings Inc. et al., No. 3:16-cv-919 (the "Benson Lawsuit"). Both the Parmelee Lawsuit and the Benson Lawsuit were filed against SC and certain of its current and former directors and executive officers on behalf of a class consisting of all those who purchased or otherwise acquired SC's securities between February 3, 2015 and March 15, 2016. The complaints in the Parmelee Lawsuit and Benson Lawsuit allege that SC made false or misleading statements, as well as failed to disclose material adverse facts as disclosed in prior annual and quarterly reports filed under the Exchange Act and certain other public disclosures, in connection with SC's change in its methodology for estimating its ACL and correction of such allowance for prior periods in SC’s Annual Report on Form 10-K for the year ended December 31, 2015. The complaints assert claims under Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder, and seek damages and other relief. Further, SC is party to, or is periodically otherwise involved in reviews, investigations, and proceedings (both formal and informal), and information-gathering requests, by government and self-regulatory agencies, including the Federal Reserve, the CFPB, the DOJ, the SEC, the FTC and various state regulatory agencies. Currently, such proceedings include a civil subpoena from the DOJ, under the FIRREA, requesting the production of documents and communications that, among other things, relate to the underwriting and securitization of nonprime auto loans since 2007. Additionally, on October 28, 2014, SC received a preservation letter and request for documents from the SEC requesting the preservation and production of documents and communications that, among other things, relate to the underwriting and securitization of auto loans since January 1, 2011. SC also has received civil subpoenas from various state Attorneys General requesting similar documents and communications. SC is complying with the requests for information and document preservation. On November 4, 2015, SC entered into an Assurance of Discontinuance ("AOD") with the Office of Attorney General of the Commonwealth of Massachusetts (the "Massachusetts AG"). The Massachusetts AG alleged that SC violated the maximum permissible interest rates allowed under Massachusetts law due to the inclusion of GAP charges in the calculation of finance charges. Among other things, the AOD requires SC, with respect to any loan that exceeded the maximum rates, to issue refunds of all finance charges paid to date and to waive all future finance charges. The AOD also requires SC to undertake certain remedial measures, including ensuring that interest rates on its loans do not exceed maximum rates (when GAP charges are included) in the future, and provides that SC pay one hundred fifty thousand dollars to the Massachusetts AG to reimburse its costs of implementing the AOD. NOTE 14. COMMITMENTS, CONTINGENCIES AND GUARANTEES (continued) On February 25, 2015 , SC entered into a consent order with the DOJ, approved by the United States District Court for the Northern District of Texas that resolves the DOJ's claims against SC that certain of its repossession and collection activities during the period of time between January 2008 and February 2013

RELATED PARTY TRANSACTIONS

RELATED PARTY TRANSACTIONS	3 Months Ended

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS The Company has various debt agreements with Santander. For a listing of these debt agreements, see Note 12 to the Condensed Consolidated Financial Statements of the Company's Annual Report on Form 10-K for the year ended December 31, 2015 . During the first quarter ended March 31, 2016 , SBNA transferred and settled $2.3 billion of unfunded commitments to extend credit to an unconsolidated related party for a loss on sale of $6.3 million , see Note 14. The Company and its affiliates also entered into or were subject to various service agreements with Santander and its affiliates. Each of these agreements was made in the ordinary course of business and on market terms. A list and description of these agreements can be found in Note 22 to the Consolidated Financial Statements of the Company's Annual Report on Form 10-K for the year ended December 31, 2015 . On July 2, 2015, the Company announced that it had entered into an agreement with former SC Chief Executive Officer Thomas G. Dundon (Mr. Dundon), Dundon DFS LLC ("DDFS"), and Santander related to Mr. Dundon's departure from SC (the “Separation Agreement”). Pursuant to the Separation Agreement, the Company was deemed to have delivered an irrevocable notice to exercise its option to acquire all of the shares of SC Common Stock owned by DDFS and consummate the transactions contemplated by the call option notice, subject to the receipt of all required regulatory approvals (the "Call Transaction"). At that date, the SC Common Stock held by DDFS (the "DDFS Shares") represented approximately 9.7% of SC Common Stock. Also, in connection with and pursuant to the Separation Agreement, on July 2, 2015, Mr. Dundon, the Company, DDFS, SC and Santander entered into an amendment to the Shareholders Agreement (the "Second Amendment"). The Second Amendment amended, for purposes of calculating the price per share to be paid in the event that a put or call option was exercised with respect to the shares of SC Common Stock owned by DDFS, the definition of the term “Average Stock Price” to mean $26.83 . The Separation Agreement did not affect Santander’s option to assume the Company’s obligation under the Call Transaction as provided in the Shareholders Agreement that was entered into by the same parties on January 28, 2014. Under the Separation Agreement, because the Call Transaction was not consummated prior to October 15, 2015 (the “Call End Date”), DDFS is free to transfer any or all of the DDFS shares, subject to the terms and conditions of the Amended and Restated Loan Agreement, dated as of July 16, 2014, between DDFS and Santander. Because the Call Transaction was not completed before the Call End Date, interest began accruing on the price paid per share in the Call Transaction at the overnight LIBOR rate on the third business day preceding the consummation of the Call Transaction plus 100 basis points with respect to the shares of SC Common Stock ultimately sold in the Call Transaction. The Amended and Restated Loan Agreement provides for a $300.0 million revolving loan which as of March 31, 2016 and December 31, 2015 had an unpaid principal balance of approximately $290.0 million . Pursuant to the Loan Agreement, 29,598,506 shares of the SC’s Common Stock owned by DDFS are pledged as collateral under a related pledge agreement. NOTE 15. RELATED PARTY TRANSACTIONS (continued) If consummated , the Company would pay DDFS approximately $928.3 million plus interest that accrued since the Call End Date. To date, the Call Transaction has not been consummated and remains subject to the receipt of the applicable regulatory approvals. The Company’s delivery of its irrevocable notice to consummate the Call Transaction created a contingent forward purchase of all of DDFS equity shares in accordance with ASC 480, Distinguishing Liabilities from Equity. Under this guidance the Company will recognize either a contingent forward asset or liability at fair value based on the movement of SC’s stock price in the market as compared to the proposed fixed settlement price of $26.83 per share. Since July 2, 2015 through March 31, 2016, SC’s stock price is lower than $26.83 which would indicate a potential recognition of a contingent forward purchase obligation. The Company’s estimate of the fair value of the contingent forward purchase obligation, based on its assessment of the likelihood of obtaining the required regulatory approvals and its estimate of the accrued interest, was not material to its consolidated financial statements for the prior periods presented as well as to the current quarter. If regulatory approval is obtained, or if the probability of obtaining the regulatory approvals increases, the Company may have to recognize a material charge to earnings to recognize the change in the fair value of the contingent forward purchase contract.

FAIR VALUE

FAIR VALUE	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE General As of March 31, 2016 , $21.6 billion of the Company’s total assets consisted of financial instruments measured at fair value on a recurring basis, including financial instruments for which the Company elected the FVO. None of these financial instruments were measured using quoted market prices for identical instruments or Level 1 inputs. Approximately $19.6 billion of these financial instruments were measured using valuation methodologies involving market-based and market-derived information, or Level 2 inputs. Approximately $2.1 billion of these financial instruments were measured using model-based techniques, or Level 3 inputs, and represented approximately 9.5% of total assets measured at fair value and approximately 1.6% of total consolidated assets. Fair value is defined in GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard focuses on the exit price in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. GAAP establishes a fair value reporting hierarchy to maximize the use of observable inputs when measuring fair value and defines the three levels of inputs as noted below: • Level 1 - Assets or liabilities for which the identical item is traded on an active exchange, such as publicly-traded instruments or futures contracts. • Level 2 - Assets and liabilities valued based on observable market data for similar instruments. Fair value is estimated using inputs other than quoted prices included within Level 1 that are observable for assets or liabilities, either directly or indirectly. • Level 3 - Assets or liabilities for which significant valuation assumptions are not readily observable in the market, and instruments valued based on the best available data, some of which is internally developed and considers risk premiums that a market participant would require. Fair value is estimated using unobservable inputs that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities may include financial instruments whose value is determined using pricing services, pricing models with internally developed assumptions, discounted cash flow ("DCF") methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Assets and liabilities measured at fair value, by their nature, result in a higher degree of financial statement volatility. When available, the Company attempts to use quoted market prices or matrix pricing in active markets to determine fair value and classifies such items as Level 1 or Level 2 assets or liabilities. If quoted market prices in active markets are not available, fair value is determined using third-party broker quotes and/or DCF models incorporating various assumptions including interest rates, prepayment speeds and credit losses. Assets and liabilities valued using broker quotes and/or DCF models are classified as either Level 2 or Level 3, depending on the lowest level classification of an input that is considered significant to the overall valuation. NOTE 16. FAIR VALUE (continued) The Company values assets and liabilities based on the principal market on which each would be sold (in the case of assets) or transferred (in the case of liabilities). The principal market is the forum with the greatest volume and level of activity. In the absence of a principal market, the valuation is based on the most advantageous market. In the absence of observable market transactions, the Company considers liquidity valuation adjustments to reflect the uncertainty in pricing the instruments. The fair value of a financial asset is measured on a stand-alone basis and cannot be measured as a group, with the exception of certain financial instruments held and managed on a net portfolio basis. In measuring the fair value of a nonfinancial asset, the Company assumes the highest and best use of the asset by a market participant, not just the intended use, to maximize the value of the asset. The Company also considers whether any credit valuation adjustments are necessary based on the counterparty's credit quality. Any models used to determine fair values or validate dealer quotes based on the descriptions below are subject to review and testing as part of the Company's model validation and internal control testing processes. The Bank's Market Risk Department is responsible for determining and approving the fair values of all assets and liabilities valued at fair value, including the Company's Level 3 assets and liabilities. Price validation procedures are performed and the results are reviewed for Level 3 assets and liabilities by the Market Risk Department. Price validation procedures performed for these assets and liabilities can include comparing current prices to historical pricing trends by collateral type and vintage, comparing prices by product type to indicative pricing grids published by market makers, and obtaining corroborating dealer prices for significant securities. The Company reviews the assumptions utilized to determine fair value on a quarterly basis. Any changes in methodologies or significant inputs used in determining fair values are further reviewed to determine if a change in fair value level hierarchy has occurred. Transfers in and out of Levels 1, 2 and 3 are considered to be effective as of the end of the quarter in which they occur. There were no transfers between Levels 1, 2 and 3 during the three-month periods ended March 31, 2016 and March 31, 2015 for any assets or liabilities valued at fair value on a recurring basis. NOTE 16. FAIR VALUE (continued) Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present the assets and liabilities that are measured at fair value on a recurring basis by major product category and fair value hierarchy as of March 31, 2016 and December 31, 2015 .

Refer to Note 1 to the Condensed Consolidated Financial Statements for additional details related to this ASU implementation. (2) LHFS disclosed on the Condensed Consolidated Balance Sheet also includes LHFS that are held at the lower of cost or fair value and are not presented within this table. NOTE 16. 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: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value (in thousands) March 31, 2016 Impaired loans held-for-investment $ — $ 279,069 $ 41,118 $ 320,187 Foreclosed assets — 15,242 — 15,242 Vehicle inventory — 251,926 — 251,926 Loans held for sale — — 978,819 978,819 Indefinite lived intangibles — — 18,000 18,000 December 31, 2015 Impaired loans held-for-investment $ — $ 122,792 $ 326 $ 123,118 Foreclosed assets — 27,574 — 27,574 Vehicle inventory — 204,120 — 204,120 Loans held for sale — — 2,049,293 2,049,293 Goodwill — — 1,019,960 1,019,960 Indefinite lived intangibles — — 38,300 38,300 Valuation Processes and Techniques Impaired loans held-for-investment represents the recorded investment of impaired commercial loans for which the Company periodically records nonrecurring adjustments of collateral-dependent loans measured for impairment when establishing the ALLL. Such amounts are generally 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 where the value of the underlying collateral is determined using a combination of real estate appraisals, field examinations and internal calculations are considered Level 3 inputs. 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 total carrying value of these loans was $218.7 million and $91.3 million at March 31, 2016 and December 31, 2015 , respectively. Foreclosed assets represent the recorded investment in assets taken 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. NOTE 16. FAIR VALUE (continued) The Company's LHFS portfolios that are measured at fair value on a nonrecurring basis consist of personal and commercial LHFS. The estimated fair value for the personal and commercial 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 estimated fair value of goodwill and intangible assets are valued using unobservable inputs and are classified as Level 3. Fair value is calculated using a DCF model. 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 1 and Note 7 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: Statement of Operations Three-Month Period 2016 2015 (in thousands) Impaired loans held-for-investment Provision for credit losses $ (88,311 ) $ (570 ) Foreclosed assets Miscellaneous income (1) (1,812 ) (611 ) Loans held for sale Miscellaneous income (1) (68,338 ) — Indefinite lived intangibles Amortization of intangibles (20,300 ) — $ (178,761 ) $ (1,181 ) (1) These amounts reduce Miscellaneous income. Level 3 Rollforward for Recurring Assets and Liabilities The tables below present the changes in all Level 3 balances for the three-month periods ended March 31, 2016 and 2015 , respectively. Three-Month Period Ended March 31, 2016 Investments Retail Installment Contracts Held for Investment MSRs Derivatives Total (in thousands) Balance, December 31, 2015 $ 1,360,240 $ 328,655 $ 147,233 $ 2,146 $ 1,838,274 Gains in other comprehensive income 1,585 — — — 1,585 Gains/(losses) in earnings — 26,749 (14,356 ) 4,326 16,719 Additions/Issuances 278,686 — 3,591 — 282,277 Settlements (1) (88 ) (69,593 ) (5,726 ) 98 (75,309 ) Balance, March 31, 2016 $ 1,640,423 $ 285,811 $ 130,742 $ 6,570 $ 2,063,546 Changes in unrealized gains (losses) included in earnings related to balances still held at March 31, 2016 $ — $ 26,749 $ (14,356 ) $ (126 ) $ 12,267 (1) Settlements include charge-offs, prepayments, pay downs and maturities. NOTE 16. FAIR VALUE (continued) Three-Month Period Ended March 31, 2015 Investments Retail Installment Contracts Held for Investment MSRs Derivatives Total (in thousands) Balance, December 31, 2014 $ 1,267,643 $ 845,911 $ 145,047 $ 2,715 $ 2,261,316 Gains in other comprehensive income 4,779 — — — 4,779 Gains/(losses) in earnings — 86,492 (6,990 ) 3,826 83,328 Additions/Issuances 253,973 — 3,526 — 257,499 Settlements (1) (11,878 ) (256,306 ) (6,131 ) 96 (274,219 ) Balance, March 31, 2015 $ 1,514,517 $ 676,097 $ 135,452 $ 6,637 $ 2,332,703 Changes in unrealized gains (losses) included in earnings related to balances still held at March 31, 2015 $ — $ 86,492 $ (6,990 ) $ (110 ) $ 79,392 (1) Settlements include charge-offs, prepayments, pay downs and maturities. For the three-month periods ended March 31, 2016 and 2015 , the Company recognized $26.7 million and $86.5 million , respectively, of gains in earnings related to the RICs held for investment for which the Company elected the FVO. The gains are driven by three primary factors: 1) the recognition of interest income 2) recoveries of previously charged-off RICs and 3) actual performance of the portfolio since the Change in Control. Recoveries from RICs that were charged-off at the Change in Control dates are a direct increase to the gain recognized within the portfolio. In accordance with ASC 805, Business Combinations , the Company did not ascribe a fair value to the portfolio of sub-prime charged-off RICs at the Change in Control date. Recoveries of previously charged off loans are usually recorded as a reduction to charge-offs in the period the recovery is made, however, in instances where the FVO is elected, it will flow through the fair value mark. At the Change in Control date, the unpaid principal balance of the previously charged-off RIC portfolio was approximately $3.0 billion . Valuation Processes and Techniques - Recurring Fair Value Assets and Liabilities The following is a description of the valuation techniques used for instruments measured at fair value on a recurring basis: Securities Available-for-Sale and Trading Securities Securities accounted for at fair value include both available-for-sale and trading securities portfolios. The Company utilizes a third-party pricing service to value its investment securities portfolios. 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 vendors the Company uses provide pricing services on a global basis. 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 value. Actively traded quoted market prices for investment securities available-for-sale, 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. NOTE 16. FAIR VALUE (continued) Certain ABS are valued using DCF models. The DCF models are obtained from a third-party pricing vendor who uses observable market data and therefore are classified as Level 2. Other ABS that could not be valued using a third-party pricing service are valued using an internally-developed DCF model. When estimating the fair value using this model, the Company uses its best estimate of the key assumptions which include the discount rates and forward yield curves. The Company uses comparable bond indices based on industry, term, and rating to discount the expected future cash flows. Determining the comparability of assets involves significant subjectivity related to asset type differences, cash flows, performance and other inputs. The inability of the Company to corroborate the fair value of the ABS due to the limited available observable data on these ABS resulted in a fair value classification of Level 3. The Company's equity securities, which are comprised primarily of shares of registered mutual funds, are priced using net asset value per share practical expedient, which is validated with a sufficient level of observable activity. In accordance with the implementation of ASU 2015-07, these equity securities are not presented within the fair value hierarchy. Refer to Note 1 to the Condensed Consolidated Financial Statements for additional details related to this ASU implementation. Gains and losses on investments are recognized in the Condensed Consolidated Statements of Operations through Net gain on sale of investment securities . RICs held-for-investment For certain RICs held-for-investment, the Company has elected the FVO. The fair values of RICs are estimated using the DCF model. In estimating the fair value using this model, the Company uses significant unobservable inputs on key assumptions, which includes historical default rate and adjustments to reflect voluntary prepayments, prepayment rates based on available data from a comparable market securitization of similar assets, discount rates reflective of the cost of funding debt issuance and recent historical equity yields, recovery rates based on the average severity utilizing reported severity rates and loss severity utilizing available market data from a comparable securitized pool. Accordingly, RICs held-for-investment for which the Company has elected FVO are classified as Level 3. LHFS The Company's LHFS portfolios that are measured at fair value on a recurring basis consists 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 on the Condensed Consolidated Statements of Operations through Miscellaneous income. See further discussion below in the section captioned "FVO for Financial Assets and Financial Liabilities." NOTE 16. FAIR VALUE (continued) MSRs The model to value MSRs estimates the present value of the future net cash flows from mortgage servicing activities based on various assumptions. These cash flows include servicing and ancillary revenue, offset by the estimated costs of performing servicing activities. Significant assumptions used in the valuation of residential MSRs include changes in anticipated loan prepayment rates ("CPRs") and the discount rate, reflective of a market participant's required return on an investment for similar assets. Other important valuation assumptions include market-based servicing costs and the anticipated earnings on escrow and similar balances held by the Company in the normal course of mortgage servicing activities. All of these assumptions are considered to be unobservable inputs. Historically, servicing costs and discount rates have been less volatile than CPR and earnings rates, both of which are directly correlated with changes in market interest rates. Increases in prepayment speeds, discount rates and servicing costs result in lower valuations of MSRs. Decreases in the anticipated earnings rate on escrow and similar balances result in lower valuations of MSRs. For each of these items, the Company makes assumptions based on current market information and future expectations. All of the assumptions are based on standards that the Company believes would be utilized by market participants in valuing MSRs and are derived and/or benchmarked against independent public sources. Accordingly, MSRs are classified as Level 3. Gains and losses on MSRs are recognized on the Condensed Consolidated Statements of Operations through Mortgage banking income, net . See further discussion on MSRs in Note 8 . Listed below are the most significant inputs that are utilized by the Company in the evaluation of residential MSRs: • A 10% and 20% increase in the CPR speed would decrease the fair value of the residential servicing asset by $5.3 million and $10.3 million , respectively, at March 31, 2016 . • A 10% and 20% increase in the discount rate would decrease the fair value of the residential servicing asset by $4.4 million and $8.5 million , respectively, at March 31, 2016 . Significant increases (decreases) in any of those inputs in isolation would result in significantly higher (lower) fair value measurements. 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 widely 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 respective counterparty's nonperformance risk in the fair value measurement of its derivatives, except for those derivative contracts with associated credit support annexes which provide credit enhancements, such as collateral postings and guarantees. The Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy. Certain of the Company's derivatives utilize Level 3 inputs, which are primarily related to mortgage banking derivatives-interest rate lock commitments. NOTE 16. FAIR VALUE (continued) The DCF model is utilized to determine the fair value of the mortgage banking derivatives-interest rate lock commitments. 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. 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). Gains and losses related to derivatives affect various line items in the Condensed Consolidated Statements of Operations . See Note 11 for a discussion of derivatives activity. Level 3 Inputs - Significant Recurring Assets and Liabilities The following table presents quantitative information about the significant unobservable inputs within significant Level 3 recurring assets and liabilities.

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 Bank and SC serve. The Company has identified the following reportable segments: • The Consumer and Business Banking segment (formerly known as the Retail Banking segment) primarily comprises the Bank's branch locations, residential mortgage business and business banking customers. The branch locations offer a wide range of products and services to both consumers and business banking customers, which attract deposits by offering a variety of deposit instruments including demand and interest-bearing demand deposit accounts, money market and savings accounts, CDs and retirement savings products. The branch locations also offer consumer loans such as credit cards, and home equity loans and lines of credit, and business loans such as commercial lines of credit and business credit cards. In addition, investment services provide annuities, mutual funds, managed monies, and insurance products and acts as an investment brokerage agent to the customers of the Consumer and Business Banking segment. • The Commercial Banking segment currently provides commercial lines, loans, and deposits to medium and large business banking customers as well as financing and deposits for government entities, commercial loans to dealers and financing for commercial vehicles and municipal equipment. This segment also provides financing and deposits for government entities and niche product financing for specific industries, including oil and gas and mortgage warehousing, among others. NOTE 17. BUSINESS SEGMENT INFORMATION (continued) • The Commercial Real Estate segment offers commercial real estate loans and multifamily loans to customers. • The GCB segment was formerly designated as the Global Corporate Banking & Market & Large Corporate Banking segment and was renamed during the third quarter of 2015. This segment serves the needs of global commercial and institutional customers by leveraging the international footprint of the Santander group to provide financing and banking services to corporations with over $500 million in annual revenues. GCB'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 a ten -year private label financing agreement with FCA that became effective May 1, 2013, SC offers a full spectrum of auto financing products and services to FCA customers and dealers under the Chrysler Capital brand. These products and services include consumer RICs and leases, as well as dealer loans for inventory, construction, real estate, working capital and revolving lines of credit. SC also originates vehicle loans through a Web-based direct lending program, purchases vehicle RICs from other lenders, and services automobile, recreational and marine vehicle portfolios for other lenders. Additionally, SC has several relationships through which it provides personal loans, private label credit cards and other consumer finance products. During 2015, SC announced its intention to exit the personal lending business. SC has entered into a number of intercompany agreements with the Bank as described above as part of the Other segment. All intercompany revenue and fees between the Bank and SC are eliminated in the consolidated results of the Company. The Other category includes earnings from the investment portfolio, interest from the non-strategic assets portfolio, interest expense on the Company's borrowings and other debt obligations, amortization of intangible assets and certain unallocated corporate income and indirect expenses. For segment reporting purposes, SC continues to be managed as a separate business unit. The Company’s segment results, excluding SC, are derived from the Company’s business unit profitability reporting system by specifically attributing managed balance sheet assets, deposits and other liabilities and their related interest income or expense to each of the segments. Funds transfer pricing ("FTP") methodologies are utilized to allocate a cost for funds used or a credit for funds provided to business line deposits, loans and selected other assets using a matched funding concept. The methodology includes a liquidity premium adjustment, which considers an appropriate market participant spread for commercial loans and deposits by analyzing the mix of borrowings available to the Company with comparable maturity periods. Other income and expenses are managed directly by each business line, including fees, service charges, salaries and benefits, and other direct expenses, as well as certain allocated corporate expenses, and are accounted for within each segment’s financial results. Accounting policies for the lines of business are the same as those used in preparation of the Condensed Consolidated Financial Statements with respect to activities specifically attributable to each business line. However, the preparation of business line results requires management to establish methodologies to allocate funding costs and benefits, expenses and other financial elements to each line of business. Where practical, the results are adjusted to present consistent methodologies for the segments. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. The implementation of these enhancements to the internal management reporting methodology may materially affect the results disclosed for each segment with no impact on consolidated results. Whenever significant changes to management reporting methodologies take place, prior period information is reclassified wherever practicable. NOTE 17. BUSINESS SEGMENT INFORMATION (continued) During the first quarter of 2016, certain management and business line changes became effective as the Company reorganized its management reporting in order to improve its structure and focus to better align management teams and resources with the business goals of the Company and provide enhanced customer service to its clients. Accordingly, the following changes were made within the Company's reportable segments to provide greater focus on each of its core businesses: • The small business banking, commercial business banking, and auto leasing lines of business formerly included in the Auto Finance and Business Banking reportable segment, were combined with the Consumer and Business Banking reportable segment. • The Real Estate and Commercial reportable segment was split into the Commercial Real Estate reportable segment and the Commercial Banking reportable segment. • The CEVF and dealer floor plan lines of business, formerly included in the Auto Finance & Business Banking reportable segment were moved to the Commercial Banking business unit. • The internal FTP guidelines and methodologies were revised to align with Santander corporate criteria for internal management reporting. These FTP changes impact all reporting segments, excluding SC. All prior period results have been recast to conform to the new composition of the reportable segments. Certain segments previously deemed quantitatively significant no longer met the threshold and have been combined with the Other category as of March 31, 2016 . Prior period results have been recast to conform to the new composition of the reportable segment.

NON-GAAP FINANCIAL MEASURES The Chief Operating Decision Maker ("CODM"), as described by ASC 280, Segment Reporting, manages SC on a historical basis by reviewing the results of SC on a pre-Change in Control basis. The Results of Segments table discloses SC's operating information on the same basis that it is reviewed by SHUSA's CODM to reconcile to SC's GAAP results, purchase price adjustments and accounting for SC as an equity method investment. The Company's non-GAAP information has limitations as an analytical tool, and the reader should not consider it in isolation, or as a substitute for analysis of its results or any performance measures under GAAP as set forth in its financial statements. The reader should compensate for these limitations by relying primarily on the GAAP results and using this non-GAAP information only as a supplement to evaluate the Company's performance.

BASIS OF PRESENTATION AND ACC26

BASIS OF PRESENTATION AND ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accounting and financial reporting policies of the Company conform to accounting principles generally accepted in the United States of America ("GAAP"). These Condensed Consolidated Financial Statements include the accounts of the Company and its subsidiaries, including the Bank, SC, and certain special purpose financing trusts utilized in financing transactions that are considered variable interest entities ("VIEs"). The Company consolidates VIEs for which it is deemed the primary beneficiary. The unaudited Condensed Consolidated Financial Statements have been prepared by the Company, pursuant to Securities and Exchange Commission ("SEC") regulations. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. All intercompany balances and transactions have been eliminated in consolidation. Additionally, where applicable, the Company's accounting policies conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. However, in the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments of a normal and recurring nature necessary to present fairly the Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements of Stockholder's Equity and Condensed Consolidated Statements of Cash Flows for the periods indicated, and contain adequate disclosure for a fair presentation of this interim financial information.
Changes in Accounting Policies and Recent Accounting Developments	Changes in Accounting Policies During the first quarter of 2016, the Company adopted the following Financial Accounting Standards Board ("FASB") Accounting Standards Updates ("ASUs"), none of which had a material impact to the Company's Consolidated Financial Statements: • The Company adopted ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (Topic 718) on a prospective basis. This ASU was issued by the FASB in June 2014 and requires that a performance target that affects vesting, and could be achieved after the requisite service period, be treated as a performance condition. Application of existing guidance in Accounting Standards Codification ("ASC") 718 as it relates to awards with performance conditions that affect vesting should continue to be used to account for such awards. • The Company also adopted ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items on a prospective basis . This ASU was issued by FASB in January 2015 and eliminates the concept of extraordinary items from GAAP, which previously required the separate classification, presentation, and disclosure of extraordinary events and transactions. NOTE 1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES (continued) • The Company also adopted ASU 2015-02, Consolidation (Topic 820): Amendments to the Consolidation Analysis, which the FASB issued in February 2015. This ASU changes the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. Specifically, this ASU modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities (VOEs); eliminates the presumption that a general partner should consolidate a limited partnership; potentially changes the consolidation conclusions of reporting entities that are involved with VIEs, in particular those that have fee arrangements and related party arrangements; and provides a scope exception for reporting entities with interests held in certain money market funds and similar unregistered money market funds. As the adoption did not result in any significant impact to the Company’s consolidated financial statements, it did not result in a retrospective or modified retrospective application. • The Company also adopted ASU 2015-07, Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or Its Equivalent) on a retrospective basis . This ASU removes the requirement to categorize investments fair valued using the net asset value per share practical expedient within the fair value hierarchy. It also modifies disclosure requirements to include only investments for which the entity elects to use the practical expedient rather than the prior guidance which required disclosures for all investments eligible to use the practical expedient. • The Company also adopted ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement Period Adjustments on a prospective basis . This amendment eliminates the requirement to account for adjustments to provisional amounts recognized in a business combination retrospectively. Instead, the acquirer will recognize the adjustments to provisional amounts during the period in which the adjustments are determined, including the effect on earnings of any amounts the acquirer would have recorded in previous periods if the accounting had been completed at the acquisition date. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , superseding the revenue recognition requirements in ASC 605. This ASU requires an entity to recognize revenue for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendment includes a five-step process to assist an entity in achieving the main principle(s) of revenue recognition under ASC 605. In August 2015, the FASB issued ASU 2015-14, which formalized the deferral of the effective date of the amendment for a period of one-year from the original effective date. Following the issuance of ASU 2015-14, the amendment will be effective for the Company for the first annual period ending beginning after December 15, 2017. In March 2016, the FASB also issued ASU 2016-08, an amendment to the guidance in ASU 2014-09 which revises the structure of the indicators to provide indicators of when the entity is the principal or agent in a revenue transaction, and eliminated two of the indicators (“the entity’s consideration is in the form of a commission” and “the entity is not exposed to credit risk”) in making that determination. This amendment also clarifies that each indicator may be more or less relevant to the assessment depending on the terms and conditions of the contract. In April 2016, the FASB also issued ASU 2016-10, which clarifies the implementation guidance on identifying promised goods or services and on determining whether an entity's promise to grant a license with either a right to use the entity's intellectual property (which is satisfied at a point in time) or a right to access the entity's intellectual property (which is satisfied over time). The amendments, collectively, should be applied retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. Early adoption of the guidance is not permitted. The Company is currently evaluating the impact of adopting ASU 2014-09 and the related updates to it on its financial position, results of operations and disclosures. NOTE 2. RECENT ACCOUNTING DEVELOPMENTS (continued) In August 2014, the FASB also issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40). This ASU requires management to perform an assessment of going concern and provides specific guidance on when and how to assess or disclose going concern uncertainties. The new standard also defines terms used in the evaluation of going concern, such as "substantial doubt." Following its application, the Company will be required to perform assessments at each annual and interim period, provide an assessment period of one year from the issuance date, and make disclosures in certain circumstances in which substantial doubt is identified. The amendment will be effective for the Company for the first reporting period ending after December 15, 2016. Earlier application is permitted. The Company does not expect the adoption of this ASU to have an impact on its financial position, result of operations, or disclosures. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This amendment requires that equity investments, except those accounted for under the equity method of accounting or which result in consolidation of the investee, be measured at fair value with changes in the fair value being recorded in net income. However, equity investments that do not have readily determinable fair values will be measured at cost less impairment, if any, plus the effect of changes resulting from observable price transactions in orderly transactions or for the identical or similar investment of the same issuer. The amendment also simplifies the impairment assessment of equity instruments that do not have readily determinable fair values, eliminates the requirement to disclose methods and assumptions used to estimate fair value of instruments measured at their amortized cost on the balance sheet, requires that the disclosed fair values of financial instruments represent "exit price," requires entities to separately present in other comprehensive income the portion of the total change in fair value of a liability resulting from instrument-specific credit risk when the FVO has been elected for that liability, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or in the accompanying notes, and clarifies that an entity should evaluate the need for a valuation allowance on its deferred tax asset related to its available-for-sale securities in combination with its other deferred tax assets. This amendment will be effective for the Company for the first reporting period beginning after December 15, 2017, with earlier adoption permitted by public entities on a limited basis. Adoption of the amendment must be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, except for amendments related to equity instruments that do not have readily determinable fair values which should be applied prospectively. The Company is in the process of evaluating the impacts of the adoption of this ASU. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The guidance in this update supersedes the current lease accounting guidance for both the lessees and lessors under ASC 840, Leases. The new guidance requires lessees to evaluate whether a lease is a finance lease using criteria that are similar to what lessees use today to determine whether they have a capital lease. Leases not classified as finance leases are classified as operating leases. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. The lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to today’s guidance for operating leases. The new guidance will require lessors to account for leases using an approach that is substantially similar to the existing guidance for sales-type, direct financing leases and operating leases. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2018, with earlier adoption permitted. Adoption of the amendment must be applied on a modified retrospective approach. The Company is in the process of evaluating the impacts of the adoption of this ASU. In March 2016, the FASB issued ASU 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships. The new guidance clarifies that a change in the counterparties to a derivative contract, i.e., a novation, in and of itself, does not require the de-designation of a hedging relationship. An entity will, however, still need to evaluate whether it is probable that the counterparty will perform under the contract as part of its ongoing effectiveness assessment for hedge accounting. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. Adoption of the new guidance can be applied on a modified retrospective or prospective basis. The Company is in the process of evaluating the impacts of the adoption of this ASU. NOTE 2. RECENT ACCOUNTING DEVELOPMENTS (continued) Also in March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments . The new guidance clarifies that an exercise contingency does not need to be evaluated to determine whether it relates to interest rates and credit risk in an embedded derivative analysis of hybrid financial instruments. In other words, a contingent put or call option embedded in a debt instrument would be evaluated for possible separate accounting as a derivative instrument without regard to the nature of the exercise contingency. However, as required under existing guidance, companies will still need to evaluate other relevant embedded derivative guidance, such as whether the payoff from the contingent put or call option is adjusted based on changes in an index other than interest rates or credit risk, and whether the debt involves a substantial premium or discount. The new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. The new guidance is required to be adopted on a modified retrospective basis to all existing and future debt instruments. The Company is in the process of evaluating the impacts of the adoption of this ASU. Additionally, in March 2016, the FASB issued ASU 2016-07, Investments-Equity Method and Joint Ventures (Topic 323) . The new guidance eliminates the requirement to apply the equity method of accounting retrospectively when a reporting entity obtains significant influence over a previously held investment. Instead, the equity method of accounting should be applied prospectively from the date significant influence is obtained. Investors should add the cost of acquiring the additional interest in the investee (if any) to the current basis of their previously held interest. The new standard also provides specific guidance for available-for-sale securities that become eligible for the equity method of accounting. In those cases, any unrealized gain or loss recorded within accumulated other comprehensive income should be recognized in earnings at the date the investment initially qualifies for the use of the equity method of accounting. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. Adoption of the new guidance can be applied only a prospective basis for investments those qualify for the equity method of accounting after the effective date. The Company is in the process of evaluating the impacts of the adoption of this ASU. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) . The new guidance simplifies certain aspects related to income taxes, SCF, and forfeitures when accounting for share-based payment transactions. This new guidance will be effective for the Company for the first reporting period beginning after December 15, 2016, with earlier adoption permitted. Certain of the amendments related to timing of the recognition of tax benefits and tax withholding requirements should be applied using a modified retrospective transition method. Amendments related to the presentation of the SCF should be applied retrospectively. All other provisions may be applied on a prospective or modified retrospective basis. The Company is in the process of evaluating the impacts of the adoption of this ASU.
Subsequent Events	Subsequent Events The Company evaluated events from the date of the Condensed Consolidated Financial Statements on March 31, 2016 through the issuance of these Condensed Consolidated Financial Statements and has determined that there have been no material events that would require recognition in its Condensed Consolidated Financial Statements or disclosure in the Notes to the Condensed Consolidated Financial Statements for the three-month period ended March 31, 2016 other than the transactions disclosed within Note 10 and Note 14 of these Condensed Consolidated Financial Statements
Commercial Lending Asset Quality Indicators	Commercial Lending Asset Quality Indicators Commercial credit quality disaggregated by class of financing receivables is summarized according to standard regulatory classifications as follows: PASS. Asset is well-protected by the current net worth and paying capacity of the obligor or guarantors, if any, or by the fair value less costs to 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.
Troubled Debt Restructuring	Commercial Loan TDRs All of the Company’s commercial loan modifications are based on the circumstances of the individual customer, including specific customers' complete relationships with the Company. Loan terms are modified to meet each borrower’s specific circumstances at a point in time and may allow for modifications such as term extensions, interest rate reductions, etc. Modifications for commercial loan TDRs generally, although not always, result in bifurcation of the original loan into A and B notes. The A note is restructured to allow for upgraded risk rating and return to accrual status after a sustained period of payment performance has been achieved (typically six months for monthly payment schedules). The B note, if any, is structured as a deficiency note; the balance is charged off but the debt is usually not forgiven. Commercial TDRs are generally placed on non-accrual status until the Company believes repayment under the revised terms is reasonably assured and a sustained period of repayment performance has been achieved (typically six months for a monthly amortizing loan). As TDRs, they will be subject to analysis for specific reserves by either calculating the present value of expected future cash flows or, if collateral-dependent, calculating the fair value of the collateral less its estimated cost to sell. The TDR classification will remain on the loan until it is paid in full or liquidated. NOTE 4. LOANS AND ALLOWANCE FOR CREDIT LOSSES (continued) Consumer Loan TDRs The primary modification program for the Company’s residential mortgage and home equity portfolios is a proprietary program designed to keep customers in their homes and, when appropriate, prevent them from entering into foreclosure. The program is available to all customers facing a financial hardship regardless of their delinquency status. The main goal of the modification program is to review the customer’s entire financial condition to ensure that the proposed modified payment solution is affordable according to a specific debt-to-income ("DTI") ratio range. The main modification benefits of the program allow for term extensions, interest rate reductions, and/or deferment of principal. The Company reviews each customer on a case-by-case basis to determine which benefit or combination of benefits will be offered to achieve the target DTI range. For the Company’s other consumer portfolios, including RICs and auto loans, the terms of the modifications generally include one or a combination of the following: a reduction of the stated interest rate of the loan at a rate of interest lower than the current market rate for new debt with similar risk or an extension of the maturity date or principal forgiveness. Consumer TDRs excluding RICs are generally placed on non-accrual status until the Company believes repayment under the revised terms is reasonably assured and a sustained period of repayment performance has been achieved (typically six months for a monthly amortizing loan). Any loan that has remained current for the six months immediately prior to modification will remain on accrual status after the modification is implemented. RICs resume interest accrual as soon as they become current and continue to accrue interest as long as they remain in performing status. The TDR classification will remain on the loan until it is paid in full or liquidated. In addition to those identified as TDRs above, the guidance also requires loans discharged under Chapter 7 bankruptcy proceedings to be considered TDRs and collateral-dependent, regardless of delinquency status. TDRs that are collateral-dependent loans must be written down to fair market value and classified as non-accrual/non-performing for the remaining life of the loan. TDR Impact to Allowance for Loan and Lease Losses The ALLL is established to recognize losses inherent in funded loans intended to be held-for-investment that are probable and can be reasonably estimated. Prior to loans being placed in TDR status, the Company generally measures its allowance under a loss contingency methodology in which consumer loans with similar risk characteristics are pooled and loss experience information is monitored for credit risk and deterioration with statistical tools considering factors such as delinquency, LTV and credit scores. Upon TDR modification, the Company generally measures impairment based on a present value of expected future cash flows methodology considering all available evidence using the original effective interest rate or fair value of collateral, less costs to sell. The amount of the required ALLL is equal to the difference between the loan’s impaired value and the recorded investment. When a consumer TDR subsequently defaults, the Company generally measures impairment based on the fair value of the collateral, if applicable, less its estimated cost to sell. Typically, commercial loans whose terms are modified in a TDR will have been identified as impaired prior to modification and accounted for generally using a present value of expected future cash flows methodology, unless the loan is considered collateral-dependent. Loans considered collateral-dependent are measured for impairment based on their fair values of collateral less estimated cost to sell. Accordingly, upon TDR modification or if a TDR modification subsequently defaults, the allowance methodology remains unchanged.
