

| COMMITMENTS, CONTINGENCIES, AND GUARANTEES              | NOTE 14. 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 September 30, 2015 December 31, 2014  (in thousands)Commitments to extend credit $30,570,879 $28,792,062Unsecured revolving lines of credit — 5Letters of credit 1,890,547 1,789,666Recourse and credit enhancement exposure on sold loans 71,845 174,902Commitments to sell loans 60,921 82,791Total commitments $32,594,192 $30,839,426Commitments 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.  The following table details the amount of commitments to extend credit expiring per period as of the dates indicated:  September 30, 2015 December 31, 2014  (in thousands)One year or less $5,563,216 $5,968,468Over 1 year to 3 years 5,626,208 5,322,291Over 3 years to 5 years 12,254,421 10,810,213Over 5 years (1) 7,127,034 6,691,090Total $30,570,879 $28,792,062(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 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. 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 14.8 months. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. In the event of a draw by the beneficiary that complies with the terms of the letters of credit, the Company would be required to honor the commitment. The Company has various forms of collateral for these letters of credit, including real estate assets and other customer business assets. The maximum undiscounted exposure related to these commitments at September 30, 2015 was $1.9 billion. The fees related to letters of credit are deferred and amortized over the lives of the commitments and were immaterial to the Company’s financial statements at September 30, 2015. Management believes that the utilization rate of these letters of credit will continue to be substantially less than the amount of the commitments, as has been the Company’s experience to date. As of September 30, 2015 and December 31, 2014, the liability related to these letters of credit was $34.7 million and $73.9 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 September 30, 2015 and December 31, 2014 were lines of credit outstanding of $102.9 million and $58.8 million, respectively. NOTE 14. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued)The following table details the amount of letters of credit expiring per period as of the dates indicated:   September 30, 2015 December 31, 2014  (in thousands)One year or less $1,312,652 $1,250,124Over 1 year to 3 years 246,126 285,108Over 3 years to 5 years 310,476 248,209Over 5 years 21,293 6,225Total $1,890,547 $1,789,666Loans Sold with RecourseThe Company has loans sold with recourse that meet the definition of a guarantee. For loans sold with recourse under the terms of its multi-family 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 $589.7 million as of September 30, 2015 and $2.6 billion as of December 31, 2014. As a result of its agreement with FNMA, the Company retained a 100% first loss position on each multi-family loan sold to FNMA until the earlier to occur of (i) the aggregate approved losses on multi-family loans sold to FNMA reaching the maximum loss exposure for the portfolio as a whole of $34.4 million as of September 30, 2015 and $152.8 million as of December 31, 2014, or (ii) all of the loans sold to FNMA under this program are being 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 September 30, 2015 and December 31, 2014, the Company had $8.1 million and $40.7 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.Additionally, during the period from 1999 to 2002, residential mortgage loans were sold with recourse and credit enhancement features to FNMA and FHLMC. The remaining unpaid principal balance of these loans was $54.5 million and $55.8 million at September 30, 2015 and December 31, 2014, respectively, and the remaining maximum amount of credit exposure on these loans was $20.1 million and $22.1 million for the same periods. The Company has posted collateral in the amount of $0.9 million at September 30, 2015 and December 31, 2014 to be utilized for any losses incurred related to these loans. Commitments to Sell LoansThe 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.NOTE 14. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) Representation and Warranty Liability In the ordinary course of business, the Company sells residential loans on a non-recourse basis to certain government-sponsored entities ("GSEs") and private investors. In connection with these sales, the Company has entered into agreements containing various representations and warranties about, among other things, the ownership of the loans, the validity of the liens securing the loans, the loans' compliance with any applicable loan criteria established by the GSEs and the private investors, including underwriting standards and the ongoing existence of mortgage insurance, the absence of delinquent taxes or liens against the property securing the loans and the loans' compliance with applicable federal, state, and local laws. Breaches of these representations and warranties may require the Company to repurchase the mortgage loan, or if the loan has been foreclosed, the underlying collateral, or otherwise make whole or provide other remedies to the GSEs and the private investors. The repurchase liability is recorded within Accrued expenses and payables on the Condensed Consolidated Balance Sheet, and the related income statement activity is recorded in Mortgage banking income, net on the Condensed Consolidated Statement of Operations.  Management believes the Company's repurchase reserve appropriately reflects the estimated probable losses on repurchase claims for all loans sold and outstanding as of September 30, 2015. In making these estimates, the Company considers the losses it expects to incur over the lives of the loans sold. The table below represents the activity in the representation and warranty reserve for the dates indicated.   Three-Month PeriodEnded September 30,  Nine-Month PeriodEnded September 30,  2015 2014 2015 2014  (in thousands)Beginning Balance $23,008 $40,862 $24,266 $54,836Changes in Estimate 655 10,894 935 3,315Claims (429) (794) (1,967) (7,189)Ending Balance $23,234 $50,962 $23,234 $50,962SCUSA Commitments SCUSA is obligated to make purchase price hold-back payments to a third party originator of loans that it purchases on a periodic basis, when losses are lower than originally expected. SCUSA also is obligated to make total return settlement payments to this third-party originator in 2016 and 2017 if returns on the purchased pools are greater than originally expected. SCUSA has extended revolving lines of credit to certain auto dealers. Under this arrangement, SCUSA is committed to lend up to each dealer's established credit limit. Under terms of agreements with a peer-to-peer personal lending platform company, SCUSA was committed as of September 30, 2015 to purchase at least the lesser of $30.0 million per month or 50% of the lending platform company’s near-prime originations thereafter through July 2017. This commitment can be reduced or canceled with 90 days notice. On October 9, 2015, SCUSA sent a notice of termination to the lending platform company.  NOTE 14. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued)SCUSA 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, SCUSA has not recorded an allowance for unfunded commitments. As of September 30, 2015 and December 31, 2014, SCUSA was obligated to purchase $15.7 million and $7.7 million, respectively, in receivables that had been originated by the retailer but not yet purchased by SCUSA. SCUSA also is required to make a profit-sharing payment to the retailer each month if performance exceeds a specified return threshold. During the three months ended September 30, 2015, SCUSA and the third-party retailer executed an amendment that, among other provisions, increases the profit-sharing percentage retained by SCUSA, gives the retailer 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, gives the retailer 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"), SCUSA 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 SCUSA to originate any loans, but for each loan originated SCUSA will pay the OEM a referral fee, comprised of a volume bonus fee and a loss betterment bonus fee. The loss betterment bonus fee will be 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 retail installment contracts through securitizations and other sales, SCUSA has made standard representations and warranties customary to the consumer finance industry. Violations of these representations and warranties may require SCUSA to repurchase loans previously sold to on- or off-balance sheet trusts or other third parties. As of September 30, 2015, SCUSA had no repurchase requests outstanding. In the opinion of SCUSA management, the potential exposure of other recourse obligations related to SCUSA’s retail installment contract sales agreements will not have a material adverse effect on SCUSA’s consolidated financial position, results of operations, or cash flows.Santander has provided guarantees on the covenants, agreements, and obligations of SCUSA under the governing documents of its warehouse facilities and privately issued amortizing notes. These guarantees are limited to the obligations of SCUSA as servicer.Under terms of the agreement with Chrysler, SCUSA must make revenue sharing payments to Chrysler and also must make gain-sharing payments when residual gains on leased vehicles exceed a specified threshold.SCUSA has a flow agreement with Bank of America under which SCUSA is committed to sell up to a specified amount of eligible loans to the Bank of America each month through May 2018. Prior to October 1, 2015, the amount of this monthly commitment was $300 million. On October 1, 2015, SCUSA and Bank of America amended the flow agreement to increase the maximum commitment to sell to $350 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. SCUSA retains servicing on all sold loans and may receive or pay a servicer performance payment based on an agreed-upon formula if performance on the sold loans is better or worse, respectively, than expected performance at the time of sale. SCUSA has sold loans to Citizens Bank of Pennsylvania ("CBP") under terms of a flow agreement and predecessor sale agreements. SCUSA 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, SCUSA executed an amendment to the servicing agreement with CBP which increased the servicing fee SCUSA receives. SCUSA 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 million and a minimum of $250 million per quarter to a maximum of $200 million and a minimum of $50 million per quarter, as may be adjusted according to the agreement.In connection with the bulk sale of Chrysler Capital leases, SCUSA 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 $3.9 million as of September 30, 2015.NOTE 14. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued)On March 31, 2015, SCUSA executed a forward flow asset sale agreement with a third party under the terms of which SCUSA is committed to sell charged-off loan receivables in bankruptcy status on a quarterly basis until sales total at least $200 million in proceeds. SCUSA and the third party executed an amendment to the forward flow asset sale agreement on June 29, 2015 which increased the committed sales of charged-off loan receivables in bankruptcy status to $275 million, and another amendment on September 29, 2015 requiring sales to occur quarterly. Prior to the most recent amendment there was no requirement on the timing of sales. As of September 30, 2015, the remaining commitment was $203.4 million.Periodically, SCUSA 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 putative securities class action lawsuit was filed in the United States District Court, Southern District of New York (the "Steck Lawsuit"). On October 6, 2014, another putative securities class action lawsuit was filed in the District Court of Dallas County, Texas and was subsequently removed to the United States District Court, Northern District of Texas. Both lawsuits were filed against SCUSA, certain current and former directors and executive officers of SCUSA and certain institutions that served as underwriters in the IPO. Each lawsuit was brought by a purported stockholder of SCUSA seeking to represent a class consisting of all those who purchased or otherwise acquired securities pursuant and/or traceable to SCUSA's Registration Statement and Prospectus issued in connection with the IPO. Each complaint alleges that the Registration Statement and Prospectus contained misleading statements concerning SCUSA’s auto lending business and underwriting practices. Each lawsuit asserts claims under Section 11 and Section 15 of the Securities Act and seeks damages and other relief. In February 2015, the putative class action lawsuit pending in the United States District Court, Northern District of Texas, was voluntarily dismissed without prejudice. In June 2015, the Steck Lawsuit venue was transferred from the Southern District of New York to the Northern District of Texas. 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 lawsuit names as defendants current and former members of SCUSA’s board of directors, and names SCUSA 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 SCUSA’s subprime auto lending practices, resulting in harm to SCUSA. The complaint seeks unspecified damages and equitable relief.Further, SCUSA is party to or are otherwise involved periodically in reviews, investigations, proceedings (both formal and informal), and information-gathering requests, by government and self-regulatory agencies, including the Federal Reserve, the CFPB, the Department of Justice (the "DOJ"), the SEC, the Federal Trade Commission and various state regulatory agencies. Currently, such proceedings include a civil subpoena from the DOJ under the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 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, SCUSA 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. SCUSA also has received civil subpoenas from various state attorneys general requesting similar documents and communications. SCUSA is complying with these requests for information and document preservation.On February 25, 2015, SCUSA entered into a consent order with the DOJ, approved by the United States District Court for the Northern District of Texas, which resolves the DOJ's claims against SCUSA that certain of its repossession and collection activities during the period of time between January 2008 and February 2013 violated the Servicemembers Civil Relief Act. The consent requires SCUSA to pay a civil fine in the amount of 55 thousand, as well as at least $9.4 million to affected service members consisting of ten thousand dollars plus compensation for any lost equity (with interest) for each repossession by SCUSA and five thousand dollars for each instance where SCUSA sought to collect repossession-related fees on accounts where a repossession was conducted by a prior account holder, as well as requires SCUSA to undertake additional remedial measures.On July 31, 2015, the CFPB notified SCUSA that it had referred to the DOJ certain alleged violations by SCUSA of the Equal Credit Opportunity Act ("ECOA") regarding (i) statistical disparities in markups charged by automobile dealers to protected groups on loans originated by those dealers and purchased by SCUSA and (ii) the treatment of certain types of income in SCUSA's underwriting process. On September 25, 2015, SCUSA the DOJ notified SCUSA that it has initiated, based on the referral from the CFPB, an investigation under the ECOA of SCUSA's pricing of automobile loans.SHUSA does not believe that there are any proceedings, threatened or pending, that, if determined adversely, would have a material adverse effect on the consolidated financial position, results of operations, or liquidity of SCUSA.NOTE 14. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued) On July 2, 2015, SCUSA announced the departure of Thomas G. Dundon from his roles as Chairman of the Board and Chief Executive Officer of SCUSA, effective as of the close of business on July 2, 2015. In connection with Mr. Dundon's, and subject to the terms and conditions of his Employment Agreement, including Mr. Dundon's execution of a release of claims against SCUSA, Mr. Dundon became entitled to receive certain payments and benefits under his Employment Agreement. The Separation Agreement also provided for the modification of terms of certain equity based awards. Certain of the payments, agreements to make payments and benefits may be effective only upon receipt of certain required regulatory approvals.During the three months ended September 30, 2015, SCUSA recognized $12.3 million in severance-related expenses, and $9.9 million in stock compensation expense in connection with Mr. Dundon’s departure and the terms of the Separation Agreement. As of September 30, 2015, SCUSA had recorded a liability for $115.1 million in contemplation of the payments and benefits due under the terms of the Separation Agreement. Mr. Dundon will continue to serve as a Director of SCUSA's Board, and will serve as a consultant to SCUSA for twelve months from the date of the Separation Agreement at a mutually agreed rate, subject to required bank regulatory approvals. As of September 30, 2015, SCUSA has not made any payments to Mr. Dundon arising from or pursuant to the terms of the Separation Agreement.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 which 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 routinely 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 its subsidiaries. In the ordinary course of business, the Company and its subsidiaries are also subject to regulatory examinations, inspections, information-gathering requests, inquiries and investigations, including by the Federal Reserve, the OCC, the CFPB, the FDIC, the DOJ, the SEC, states attorney's general and other governmental and regulatory authorities. 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 loss, fines or penalties related to the matter. 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 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 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. While the outcome of legal proceedings is inherently uncertain, based on information currently available, advice of counsel and available insurance coverage, management believes that the established legal reserves at September 30, 2015 are adequate and the liabilities arising from legal proceedings will not have a material adverse effect on the consolidated financial position, consolidated results of operations or consolidated cash flows. However, in the event of unexpected future developments, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the consolidated financial position, consolidated results of operations or consolidated cash flows of the Company.  NOTE 14. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued)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 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 April 13, 2011, the Bank and other parties signed a consent order with the Office of Thrift Supervision ("OTS") resolving certain of the Bank's and other parties' foreclosure activities (the "OTS Order") by the Bank's previous primary federal banking regulator, the OTS, as part of an interagency horizontal review of foreclosure practices at 14 mortgage servicers. Upon its conversion to a national bank on January 26, 2012, the Bank entered into a stipulation consenting to the issuance of a consent order by the OCC, which contains the same terms as the OTS Order (the "Order").  On January 7, 2013, the Bank and nine other mortgage servicing companies subject to enforcement actions for deficient practices in mortgage loan servicing and foreclosure processing reached an agreement in principle with the OCC and the Federal Reserve to make cash payments and provide other assistance to borrowers. On February 28, 2013, the agreements were finalized with all ten mortgage servicing companies, including the Bank. Other assistance includes reductions of principal on first and second lien mortgage loans, payments to assist with short sales, deficiency balance waivers on past foreclosures and short sales, and forbearance assistance for unemployed homeowners. As of January 24, 2013, twelve other mortgage servicing companies subject to enforcement action for deficient practices in mortgage loan servicing and foreclosure processes also reached an agreement with the OCC or the Federal Reserve, as applicable. As a result of this agreement, the participating servicers, including the Bank, ceased their independent foreclosure reviews, which involved case-by-case reviews, and replaced them with a broader framework allowing eligible borrowers to receive compensation in a more timely manner. This arrangement has not eliminated all of the Company's risks associated with foreclosures, since it does not protect the Bank from potential individual borrower claims, class actions lawsuits, actions by state attorneys general, or actions by the DOJ or other regulators. In addition, all of the other terms of the Order are still in effect. Under the agreement, the Bank has paid $6.2 million into a remediation fund, the majority of which has been distributed to borrowers, and will engage in foreclosure avoidance activities, such as loan modifications and short sales over the next two years in an aggregate principal amount of $9.9 million. In return, the OCC waived any civil money penalties that could have been assessed against the Bank. During 2013, the Company submitted for credit from the OCC mortgage loans in the amount of $74.1 million, which represents the principal balance of mortgage loans for which the Bank completed foreclosure avoidance activities with its borrowers. The Bank represents 0.17% of the total $9.3 billion settlement among the banks and is the smallest participant in the agreement. The total $16.1 million related to the remediation fund and mortgage modifications was fully reserved. NOTE 14. COMMITMENTS, CONTINGENCIES, AND GUARANTEES (continued)On June 16, 2015, the Bank entered into a consent order amending the Order and the 2013 amendment to the Order (the “2015 Amendment”). The 2015 Amendment states that the Bank has not fully complied with the terms of the OTS Order and that nine actionable items under the OTS Order, as amended, remain. The 2015 Amendment imposes certain supervisory restrictions on the Bank’s mortgage origination and servicing business. These restrictions require the Bank to obtain prior supervisory non-objection 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 may generally operate its current mortgage origination and servicing business in the ordinary course. The Bank continues its efforts to close the nine actionable items identified in the 2015 Amendment.  The 2015 Amendment confirmed that the Bank has fulfilled its obligations under the OTS Order to pay $6.2 million into the remediation fund referenced above and to engage in foreclosure avoidance activities in an aggregate principal amount of at least $9.9 million.Identity Theft Protection Product Matter The Bank has 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. To date, the Bank has made $37.6 million in total remediation payments to customers. On April 17, 2015, the OCC announced that it had reached an agreement with the Bank that resolved issues related to the sale and servicing of the identity theft protection product (the "Consent Order"). Pursuant to the Consent Order, the Bank has 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 identify theft protection product. As indicated above, as of December 31, 2014, all customers were refunded amounts paid for product enrollment. The Bank is in the process of further remediating customers, in the approximate amount of $4.7 million, customers whose checking accounts may have been charged an overdraft fee or credit card accounts an over limit fee and/or finance charge as a result of the identity theft protection product fees. In reaching this Consent Order, the Bank has cooperated fully with the OCC and is working to finalize its response to comply fully with the terms of the Consent Order.Marketing of Overdraft CoverageOn 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 automatic teller machine 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. |
