Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Company Capital One Financial Corporation, a Delaware Corporation established in 1994 and headquartered in McLean, Virginia, is a diversified financial services holding company with banking and non-banking subsidiaries. Capital One Financial Corporation and its subsidiaries (the “Company”) offer a broad array of financial products and services to consumers, small businesses and commercial clients through branches, the internet and other distribution channels. As of March 31, 2016 , our principal subsidiaries included: • Capital One Bank (USA), National Association (“COBNA”), which offers credit and debit card products, other lending products and deposit products; and • Capital One, National Association (“CONA”), which offers a broad spectrum of banking products and financial services to consumers, small businesses and commercial clients. The Company and its subsidiaries are hereafter collectively referred to as “we,” “us” or “our.” COBNA and CONA are collectively referred to as the “Banks.” We also offer products outside of the United States of America (“U.S.”) principally through Capital One (Europe) plc (“COEP”), an indirect subsidiary of COBNA organized and located in the United Kingdom (“U.K.”) and through a branch of COBNA in Canada. COEP has authority, among other things, to provide credit card loans. Our branch of COBNA in Canada also has the authority to provide credit card loans. Our principal operations are currently organized for management reporting purposes into three major business segments, which are defined based on the products and services provided or the type of customer served: Credit Card, Consumer Banking and Commercial Banking. We provide details on our business segments, the integration of recent acquisitions into our business segments and the allocation methodologies and accounting policies used to derive our business segment results in “ Note 13—Business Segments .” On December 1, 2015, we completed the acquisition of the Healthcare Financial Services business of General Electric Capital Corporation (“HFS acquisition”). During the first quarter of 2016, we recorded measurement period adjustments which modestly reduced the value of certain identifiable assets acquired, with a corresponding increase to goodwill. Including post-closing purchase price adjustments during the first quarter of 2016, total cash consideration for the acquisition was $9.0 billion , including $180 million of cash acquired, and we recognized approximately $9.2 billion in assets, including $8.2 billion of loans, $134 million of intangible assets and $514 million in goodwill. We continue to expect to finalize the accounting for assets acquired and liabilities assumed in the HFS acquisition by June 30, 2016. Basis of Presentation and Use of Estimates The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the related disclosures. These estimates are based on information available as of the date of the consolidated financial statements. While management makes its best judgment, actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair statement of this interim financial information. Certain prior period amounts have been reclassified to conform to the current period presentation. Principles of Consolidation The consolidated financial statements include the accounts of Capital One Financial Corporation and all other entities in which we have a controlling financial interest. We determine whether we have a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (“VIE”). All significant intercompany account balances and transactions have been eliminated. New Accounting Standards Adopted Consolidation: Amendments to the Consolidation Analysis In February 2015, the Financial Accounting Standards Board (“FASB”) issued revised guidance for evaluating whether organizations should consolidate certain legal entities such as limited partnerships, limited liability corporations and securitization structures. The guidance also removed the indefinite deferral of specialized guidance for certain investment funds. We adopted the guidance effective in the first quarter of 2016 on a modified retrospective basis. Our adoption of this guidance did not have an impact on our financial condition, results of operations or liquidity. See “ Note 6—Variable Interest Entities and Securitizations ”for information regarding our involvement with VIEs. Recently Issued but Not Yet Adopted Accounting Standards Improvements to Employee Share-Based Accounting In March 2016, the FASB issued revised guidance for accounting for employee share-based payments, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance is effective beginning on January 1, 2017, with early adoption permitted. We do not believe the impact of this guidance will be material to our consolidated financial statements. Leases In February 2016, the FASB issued revised guidance for leases. The guidance requires lessees to recognize right of use assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements for all leases, with certain practical expedients. This will be effective for us on January 1, 2019, with early adoption permitted. We are currently assessing the potential impact on our consolidated financial statements. Revenue from Contracts with Customers In May 2014, the FASB issued revised guidance for the recognition, measurement and disclosure of revenue from contracts with customers. The guidance is applicable to all entities and, once effective, will replace significant portions of existing industry and transaction-specific revenue recognition rules with a more principles-based recognition model. Most revenue associated with financial instruments, including interest and loan origination fees, is outside the scope of the guidance. Gains and losses on investment securities, derivatives and sales of financial instruments are similarly excluded from the scope. Subsequent to issuance of the revenue recognition guidance, the FASB has issued several updates that (i) deferred by one year the effective date for revenue recognition guidance to January 1, 2018, with early adoption permitted effective January 1, 2017; (ii) clarified its guidance for performing the principle-versus-agent analysis; and (iii) clarified guidance for identifying performance obligations allowing entities to ignore immaterial promised goods and services in the context of a contract with a customer. Entities can elect to adopt the guidance either on a full or modified retrospective basis. Full retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the earliest comparative period presented. Modified retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance. We do not plan to early adopt the guidance. We are currently assessing the potential impact of this new guidance on our consolidated financial statements and which transition method we plan to elect.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	NOTE 2—DISCONTINUED OPERATIONS Shutdown of Mortgage Origination Operations of our Wholesale Mortgage Banking Unit In the third quarter of 2007, we closed the mortgage origination operations of our wholesale mortgage banking unit, GreenPoint Mortgage Funding Inc. (“GreenPoint”), which we acquired in December 2006 as part of the North Fork Bancorporation, Inc. (“North Fork”) acquisition. The results of the wholesale banking unit have been accounted for as a discontinued operation and are therefore not included in our results from continuing operations for the three months ended March 31, 2016 and 2015 . We have no significant continuing involvement in these operations. The following table summarizes the results from discontinued operations related to the closure of the mortgage origination operations of our wholesale mortgage banking unit: Table 2.1: Results of Discontinued Operations Three Months Ended March 31, (Dollars in millions) 2016 2015 Non-interest income (expense), net $ (8 ) $ 30 Income (loss) from discontinued operations before income taxes (8 ) 30 Income tax provision (benefit) (3 ) 11 Income (loss) from discontinued operations, net of tax $ (5 ) $ 19 The discontinued mortgage origination operations of our wholesale mortgage banking unit had remaining assets which primarily consisted of a deferred tax asset related to the reserve for representations and warranties on loans previously sold to third parties. See “ Note 14—Commitments, Contingencies, Guarantees and Others ” for information related to reserves we have established for our mortgage representation and warranty exposure.

As of March 31, 2016 , our investments in non-agency RMBS and CMBS, other ABS and other securities accounted for $36 million , or 28% , of total gross unrealized losses on securities available for sale. As of March 31, 2016 , the carrying value of approximately 30 securities classified as held to maturity exceeded their fair value by $7 million . Gross unrealized losses on our investment securities have decreased since December 31, 2015. The unrealized losses related to investment securities for which we have not recognized credit impairment were primarily attributable to changes in market interest rates. As discussed in more detail below, we conduct periodic reviews of all investment securities with unrealized losses to assess whether impairment is other-than-temporary. Maturities and Yields of Investment Securities The following tables summarize the remaining scheduled contractual maturities, assuming no prepayments, of our investment securities as of March 31, 2016 . Table 3.5: Contractual Maturities of Securities Available for Sale March 31, 2016 (Dollars in millions) Amortized Cost Fair Value Due in 1 year or less $ 505 $ 505 Due after 1 year through 5 years 5,545 5,584 Due after 5 years through 10 years 2,194 2,234 Due after 10 years (1) 31,295 31,769 Total $ 39,539 $ 40,092 __________ (1) Investments with no stated maturities, which consist of equity securities, are included with contractual maturities due after 10 years.

The table below summarizes, by major security type, the expected maturities and weighted-average yields of our investment securities as of March 31, 2016 . Table 3.7: Expected Maturities and Weighted-Average Yields of Securities March 31, 2016 (Dollars in millions) Due in 1 Year or Less Due > 1 Year through 5 Years Due > 5 Years through 10 Years Due > 10 Years Total Fair value of securities available for sale: U.S. Treasury securities $ 214 $ 4,233 $ 519 $ 0 $ 4,966 RMBS: Agency 323 17,587 7,457 0 25,367 Non-agency 14 851 1,535 501 2,901 Total RMBS 337 18,438 8,992 501 28,268 CMBS: Agency 55 1,846 1,854 0 3,755 Non-agency 117 516 1,116 0 1,749 Total CMBS 172 2,362 2,970 0 5,504 Other ABS 110 846 82 0 1,038 Other securities 210 5 0 101 316 Total securities available for sale $ 1,043 $ 25,884 $ 12,563 $ 602 $ 40,092 Amortized cost of securities available for sale $ 1,048 $ 25,625 $ 12,295 $ 571 $ 39,539 Weighted-average yield for securities available for sale (1) 1.03 % 2.01 % 3.19 % 7.40 % 2.43 % Carrying value of securities held to maturity: U.S. Treasury securities $ 0 $ 199 $ 0 $ 0 $ 199 Agency RMBS 7 3,705 14,583 3,533 21,828 Agency CMBS 0 133 2,464 456 3,053 Total securities held to maturity $ 7 $ 4,037 $ 17,047 $ 3,989 $ 25,080 Fair value of securities held to maturity $ 7 $ 4,183 $ 17,996 $ 4,268 $ 26,454 Weighted-average yield for securities held to maturity (1) 7.13 % 2.71 % 2.57 % 3.36 % 2.72 % __________ (1) The weighted-average yield represents the effective yield for the investment securities and is calculated based on the amortized cost of each security. Other-Than-Temporary Impairment We evaluate all securities in an unrealized loss position at least on a quarterly basis, and more often as market conditions require, to assess whether the impairment is other-than-temporary. Our OTTI assessment is based on a discounted cash flow analysis which requires careful use of judgments and assumptions. A number of qualitative and quantitative criteria may be considered in our assessment as applicable, including the size and the nature of the portfolio; historical and projected performance such as prepayment, default and loss severity for the RMBS portfolio; recent credit events specific to the issuer and/or industry to which the issuer belongs; the payment structure of the security; external credit ratings of the issuer and any failure or delay of the issuer to make scheduled interest or principal payments; the value of underlying collateral; our intent and ability to hold the security; and current and projected market and macro-economic conditions. If we intend to sell a security in an unrealized loss position or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, the entire difference between the amortized cost basis of the security and its fair value is recognized in earnings. As of March 31, 2016 , for any securities with unrealized losses recorded in AOCI, we do not intend to sell nor believe that we will be required to sell these securities prior to recovery of their amortized cost. For those securities that we do not intend to sell nor expect to be required to sell, an analysis is performed to determine if any of the impairment is due to credit-related factors or whether it is due to other factors, such as interest rates. Credit-related impairment is recognized in earnings, with the remaining unrealized non-credit-related impairment recorded in AOCI. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected cash flows, discounted based on the effective yield. The table below presents a rollforward of the credit-related OTTI recognized in earnings for the three months ended March 31, 2016 and 2015 on investment securities for which we had no intent to sell.

We pledged securities available for sale with a fair value of $1.6 billion and $1.7 billion as of March 31, 2016 and December 31, 2015 , respectively. We also pledged securities held to maturity with a carrying value of $8.5 billion and $8.7 billion as of March 31, 2016 and December 31, 2015 , respectively.

Receivables [Abstract]
Loans	NOTE 4—LOANS Loan Portfolio Composition Our loan portfolio consists of loans held for investment, including loans underlying our consolidated securitization trusts, and loans held for sale, and is divided into three portfolio segments: credit card, consumer banking and commercial banking. Credit card loans consist of domestic and international credit card loans. Consumer banking loans consist of auto, home and retail banking loans. Commercial banking loans consist of commercial and multifamily real estate, commercial and industrial, and small-ticket commercial real estate loans. Our portfolio of loans held for investment also includes certain of our consumer and commercial loans acquired through business combinations that were recorded at fair value at acquisition and subsequently accounted for based on cash flows expected to be collected, which were referred to as “purchased credit-impaired loans” or “PCI loans.” See “ Note 1—Summary of Significant Accounting Policies ” in our 2015 Form 10-K for additional information on the accounting guidance for these loans. Credit Quality We closely monitor economic conditions and loan performance trends to manage and evaluate our exposure to credit risk. Trends in delinquency rates are an indicator, among other considerations, of credit risk within our loan portfolio. The level of nonperforming loans represents another indicator of the potential for future credit losses. Accordingly, key metrics we track and use in evaluating the credit quality of our loan portfolio include delinquency and nonperforming loan rates, as well as net charge-off rates and our internal risk ratings of larger balance commercial loans. The table below presents the composition and an aging analysis of our loans held for investment portfolio, which includes loans underlying our consolidated securitization trusts, as of March 31, 2016 and December 31, 2015 . The delinquency aging includes all past due loans, both performing and nonperforming.

We pledge loan collateral at the FHLB to secure borrowing capacity. The outstanding balances of the pledged loans totaled $35.6 billion as of March 31, 2016, and $36.9 billion as of December 31, 2015. Table 4.2 presents the outstanding balance of loans 90 days or more past due that continue to accrue interest and loans classified as nonperforming as of March 31, 2016 and December 31, 2015 .

PCI loans are excluded from loans reported as 90 days and accruing interest as well as nonperforming loans. See “ Note 1—Summary of Significant Accounting Policies ” in our 2015 Form 10-K for additional information on our policies for nonperforming loans. Credit Card Our credit card loan portfolio is highly diversified across millions of accounts and numerous geographies without significant individual exposure. We therefore generally manage credit risk on a portfolio basis. The risk in our credit card loan portfolio correlates to broad economic trends, such as unemployment rates and home values, as well as customer liquidity, all of which can have a material effect on credit performance. The primary factors we assess in monitoring the credit quality and risk of our credit card portfolio are delinquency and charge-off trends, including an analysis of the migration of loans between delinquency categories over time. The table below displays the geographic profile of our credit card loan portfolio as of March 31, 2016 and December 31, 2015 . We also present net charge-offs for the three months ended March 31, 2016 and 2015 .

The net charge-off rate is calculated for each loan category by dividing annualized net charge-offs by average loans held for investment for the period. Net charge-offs and the net charge-off rate are impacted periodically by fluctuations in recoveries, including debt sales. Consumer Banking Our consumer banking loan portfolio consists of auto, home and retail banking loans. Similar to our credit card loan portfolio, the risk in our consumer banking loan portfolio correlates to broad economic trends, such as unemployment rates, gross domestic product (“GDP”) and home values, as well as customer liquidity, all of which can have a material effect on credit performance. Delinquency, nonperforming loans and charge-off trends are key factors we assess in monitoring the credit quality and risk of our consumer banking loan portfolio. The table below displays the geographic profile of our consumer banking loan portfolio, including PCI loans. We also present the delinquency and nonperforming loan rates of our consumer banking loan portfolio as of March 31, 2016 and December 31, 2015 , as well as net charge-offs for the three months ended March 31, 2016 and 2015 .

Home Loan Our home loan portfolio consists of both first-lien and second-lien residential mortgage loans. In evaluating the credit quality and risk of our home loan portfolio, we continually monitor a variety of mortgage loan characteristics that may affect the default experience on this loan portfolio, such as vintage, geographic concentrations, lien priority and product type. Certain loan concentrations have experienced higher delinquency rates as a result of the significant decline in home prices after the peak in 2006 and subsequent rise in unemployment. These loan concentrations include loans originated between 2006 and 2008 in an environment of decreasing home sales, broadly declining home prices and more relaxed underwriting standards. The following table presents the distribution of our home loan portfolio as of March 31, 2016 and December 31, 2015 , based on selected key risk characteristics.

(2) The PCI loans balances with an origination date in the years subsequent to 2012 are related to refinancing of previously acquired home loans. (3) States listed represents those which have the highest individual concentration of home loans. Our recorded investment in home loans that are in process of foreclosure was $451 million as of March 31, 2016 . We commence the foreclosure process on home loans when a borrower becomes at least 120 days delinquent in accordance with Consumer Financial Protection Bureau regulations. Foreclosure procedures and time lines vary according to state law. As of March 31, 2016 and December 31, 2015 , the carrying value of the foreclosed residential real estate properties we hold and report as other assets on our consolidated balance sheet totaled $111 million and $123 million , respectively. Commercial Banking We evaluate the credit risk of commercial loans individually and use a risk-rating system to determine credit quality. We assign internal risk ratings to loans based on relevant information about the ability of borrowers to service their debt. In determining the risk rating of a particular loan, some of the factors considered are the borrower’s current financial condition, historical and projected future credit performance, prospects for support from financially responsible guarantors, the estimated realizable value of any collateral and current economic trends. The scale based on our internal risk rating system is as follows: • Noncriticized: Loans that have not been designated as criticized, frequently referred to as “pass” loans. • Criticized performing: Loans in which the financial condition of the obligor is stressed, affecting earnings, cash flows or collateral values. The borrower currently has adequate capacity to meet near-term obligations; however, the stress, left unabated, may result in deterioration of the repayment prospects at some future date. • Criticized nonperforming: Loans that are not adequately protected by the current net worth and paying capacity of the obligor or the collateral pledged, if any. Loans classified as criticized nonperforming have a well-defined weakness, or weaknesses, which jeopardize the full repayment of the debt. These loans are characterized by the distinct possibility that we will sustain a credit loss if the deficiencies are not corrected and are generally placed on nonaccrual status. We use our internal risk rating system for regulatory reporting, determining the frequency of credit exposure reviews, and evaluating and determining the allowance for loan and lease losses for commercial loans. Loans of $1 million or more that are designated as criticized performing and criticized nonperforming are reviewed quarterly by management to determine if they are appropriately classified/rated and whether any impairment exists. Noncriticized loans greater than $1 million are specifically reviewed, at least annually, to determine the appropriate risk rating. In addition, we evaluate the risk rating during the renewal process of any loan or if a loan becomes past due. The following table presents the geographic distribution and internal risk ratings of our commercial loan portfolio as of March 31, 2016 and December 31, 2015 .

Impaired loans without an allowance generally represent loans that have been charged down to the fair value of the underlying collateral for which we believe no additional losses have been incurred, or where the fair value of the underlying collateral meets or exceeds the loan’s amortized cost. (2) The average recorded investment of credit card loans includes finance charges and fees. (3) Although auto loans from loan recovery inventory are not reported in our loans held for investment, they are included as impaired loans above since they are reported as TD Rs. The total recorded investment of loans modified in TDRs represents $1.9 billion and $1.8 billion of the impaired loans presented above as of March 31, 2016 and December 31, 2015 , respectively. Consumer TDRs classified as performing totaled $1.0 billion as of both March 31, 2016 and December 31, 2015 . Commercial TDRs classified as performing totaled $305 million and $334 million as of March 31, 2016 and December 31, 2015 , respectively. As part of our loan modification programs to borrowers experiencing financial difficulty, we may provide multiple concessions to minimize our economic loss and improve long-term loan performance and collectability.

Paydowns, net charge-offs and any other changes subsequent to the TDR date are not reflected in the recorded investment amount (2) We present the modification types utilized most prevalently across our loan portfolios. As not every modification type is included in the table above, the total % of TDR activity may not add up to 100%. (3) Represents percentage of loans modified and accounted for as TDRs during the period that were granted a reduced interest rate. (4) Due to multiple concessions granted to some troubled borrowers, percentages may total more than 100% for certain loan types. (5) Represents weighted average interest rate reduction for those loans that received an interest rate concession. (6) Represents percentage of loans modified and accounted for as TDRs during the period that were granted a maturity date extension. (7) Represents weighted average change in maturity date for those loans that received a maturity date extension. (8) Represents percentage of loans modified and accounted for as TDRs during the period that were granted forgiveness or forbearance of a portion of their balance. (9) Total amount represents the gross balance forgiven. For loans modified in bankruptcy, the gross balance reduction represents collateral value write-downs associated with the discharge of the borrower’s obligations. TDR—Subsequent Defaults of Completed TDR Modifications The following table presents the type, number and recorded investment amount of loans modified in TDRs that experienced a default during the period and had completed a modification event in the twelve months prior to the default. A default occurs if the loan is either 90 days or more delinquent, has been charged off as of the end of the period presented or has been reclassified from accrual to nonaccrual status.

Allowance for Loans and Lease Losses	NOTE 5—ALLOWANCE FOR LOAN AND LEASE LOSSES AND RESERVE FOR UNFUNDED LENDING COMMITMENTS Our allowance for loan and lease losses represents management’s best estimate of incurred loan and lease losses inherent in our loans held for investment portfolio as of each balance sheet date. In addition to the allowance for loan and lease losses, we also estimate probable losses related to unfunded lending commitments, such as letters of credit, financial guarantees and binding unfunded loan commitments. The provision for losses on unfunded lending commitments is included in the provision for credit losses in our consolidated statements of income and the related reserve for unfunded lending commitments is included in other liabilities on our consolidated balance sheets. See “ Note 1—Summary of Significant Accounting Policies ” of our 2015 Form 10-K for further discussion on the methodology and policy for determining our allowance for loan and lease losses for each of our loan portfolio segments, as well as information on our reserve for unfunded lending commitments. Allowance for Loan and Lease Losses and Reserve for Unfunded Lending Commitments Activity The table below summarizes changes in the allowance for loan and lease losses and reserve for unfunded lending commitments by portfolio segment for the three months ended March 31, 2016 and 2015 .

(2) Represents foreign currency translation adjustments and the net impact of loan transfers and sales. Components of Allowance for Loan and Lease Losses by Impairment Methodology The table below presents the components of our allowance for loan and lease losses by portfolio segment and impairment methodology with the recorded investment of the related loans as of March 31, 2016 and December 31, 2015 . Table 5.2: Components of Allowance for Loan and Lease Losses by Impairment Methodology March 31, 2016 (Dollars in millions) Credit Card Consumer Banking Commercial Banking Other Total Allowance for loan and lease losses: Collectively evaluated (1) $ 3,572 $ 829 $ 520 $ 3 $ 4,924 Asset-specific (2) 213 51 193 0 457 PCI loans (3) 0 34 1 0 35 Total allowance for loan and lease losses $ 3,785 $ 914 $ 714 $ 3 $ 5,416 Loans held for investment: Collectively evaluated (1) $ 92,041 $ 52,247 $ 61,954 $ 82 $ 206,324 Asset-specific (2) 658 709 1,354 0 2,721 PCI loans (3) 0 17,635 933 0 18,568 Total loans held for investment $ 92,699 $ 70,591 $ 64,241 $ 82 $ 227,613 Allowance as a percentage of period-end loans held for investment 4.08% 1.29% 1.11% 4.15% 2.38% December 31, 2015 (Dollars in millions) Credit Consumer Banking Commercial Banking Other Total Allowance for loan and lease losses: Collectively evaluated (1) $ 3,445 $ 778 $ 517 $ 4 $ 4,744 Asset-specific (2) 209 54 86 0 349 PCI loans (3) 0 36 1 0 37 Total allowance for loan and lease losses $ 3,654 $ 868 $ 604 $ 4 $ 5,130 Loans held for investment: Collectively evaluated (1) $ 95,459 $ 51,113 $ 61,424 $ 88 $ 208,084 Asset-specific (2) 666 699 884 0 2,249 PCI loans (3) 0 18,560 958 0 19,518 Total loans held for investment $ 96,125 $ 70,372 $ 63,266 $ 88 $ 229,851 Allowance as a percentage of period-end loans held for investment 3.80% 1.23% 0.95% 4.94% 2.23% __________ (1) The component of the allowance for loan and lease losses for credit card and other consumer loans that we collectively evaluate for impairment is based on a statistical calculation supplemented by management judgment and interpretation. The component of the allowance for loan and lease losses for commercial loans that we collectively evaluate for impairment is based on historical loss experience for loans with similar characteristics and consideration of credit quality supplemented by management judgment and interpretation. (2) The asset-specific component of the allowance for loan and lease losses for smaller-balance impaired loans is calculated on a pool basis using historical loss experience for the respective class of assets. The asset-specific component of the allowance for loan and lease losses for larger-balance commercial loans is individually calculated for each loan. (3) The PCI loans component of the allowance for loan and lease losses is accounted for based on expected cash flows. See “ Note 1—Summary of Significant Accounting Policies ” in our 2015 Form 10-K for details on these loans. We have certain credit card partnership arrangements in which our partner agrees to share in a portion of the credit losses associated with the partnership. The loss sharing amounts due from these partners result in reductions to reported net charge-offs and provision for credit losses. The table below summarizes these impacts for the three months ended March 31, 2016 and 2015 . Table 5.3: Summary of Loss Sharing Arrangements Impact Three Months Ended March 31, (Dollars in millions) 2016 2015 Reduction in net charge-offs $ 52 $ 44 Reduction in provision for credit losses 55 57 The expected reimbursement from these partners, which is netted against our allowance for loan and lease losses, was approximately $197 million and $194 million as of March 31, 2016 and December 31, 2015 , respectively. See “ Note 1—Summary of Significant Accounting Policies ” of our 2015 Form 10-K for further discussion on our credit card partnership agreements.

Variable Interest Entities and Securitization [Abstract]
Variable Interest Entities and Securitizations	NOTE 6—VARIABLE INTEREST ENTITIES AND SECURITIZATIONS In the normal course of business, we enter into various types of transactions with entities that are considered to be VIEs. Our primary involvement with VIEs has been related to our securitization transactions in which we transferred assets from our balance sheet to securitization trusts. We have primarily securitized credit card loans and home loans, which have provided a source of funding for us and enabled us to transfer a certain portion of the economic risk of the loans or debt securities to third parties. The entity that has a controlling financial interest in a VIE is referred to as the primary beneficiary and is required to consolidate the VIE. The majority of the VIEs in which we are involved have been consolidated in our financial statements. Summary of Consolidated and Unconsolidated VIEs The table below presents a summary of VIEs, aggregated based on VIEs with similar characteristics, in which we had continuing involvement or held a variable interest as of March 31, 2016 and December 31, 2015 . We separately present information for consolidated and unconsolidated VIEs. For consolidated VIEs, we present the carrying amount of assets and liabilities reflected on our consolidated balance sheets. The assets of consolidated VIEs primarily consist of cash and loans, which we report on our consolidated balance sheets under restricted cash and loans held in consolidated trusts, respectively. The assets of a particular VIE are the primary source of funds to settle its obligations. The creditors of the VIEs typically do not have recourse to the general credit of the Company. The liabilities primarily consist of debt securities issued by the VIEs, which we report under securitized debt obligations. For unconsolidated VIEs, we present the carrying amount of assets and liabilities reflected on our consolidated balance sheets and our maximum exposure to loss. Our maximum exposure to loss is estimated based on the unlikely event that all of the assets in the VIEs become worthless and we are required to meet our maximum remaining funding obligations. Table 6.1: Carrying Amount of Consolidated and Unconsolidated VIEs March 31, 2016 Consolidated Unconsolidated (Dollars in millions) Carrying Amount of Assets Carrying Amount of Liabilities Carrying Amount of Assets Carrying Amount of Liabilities Maximum Exposure to Loss Securitization-Related VIEs: Credit card loan securitizations (1) $ 32,869 $ 15,600 $ 0 $ 0 $ 0 Home loan securitizations (2) 0 0 201 26 863 Total securitization-related VIEs 32,869 15,600 201 26 863 Other VIEs: Affordable housing entities 115 0 3,804 528 3,804 Entities that provide capital to low-income and rural communities 687 126 71 0 71 Other 0 0 116 0 116 Total other VIEs 802 126 3,991 528 3,991 Total VIEs $ 33,671 $ 15,726 $ 4,192 $ 554 $ 4,854 December 31, 2015 Consolidated Unconsolidated (Dollars in millions) Carrying Amount of Assets Carrying Amount of Liabilities Carrying Amount of Assets Carrying Amount of Liabilities Maximum Exposure to Loss Securitization-Related VIEs: Credit card loan securitizations (1) $ 34,800 $ 16,925 $ 0 $ 0 $ 0 Home loan securitizations (2) 0 0 211 27 873 Total securitization-related VIEs 34,800 16,925 211 27 873 Other VIEs: Affordable housing entities 0 0 3,852 555 3,852 Entities that provide capital to low-income and rural communities 352 101 0 0 0 Other 0 0 57 0 57 Total other VIEs 352 101 3,909 555 3,909 Total VIEs $ 35,152 $ 17,026 $ 4,120 $ 582 $ 4,782 __________ (1) Represents the gross amount of assets and liabilities owned by the VIE, which includes the seller’s interest and repurchased notes held by other related parties. (2) The carrying amount of assets of unconsolidated securitization-related VIEs consists of retained interests associated with the securitization of option-adjustable rate mortgage (“option-ARM”) loans and letters of credit related to manufactured housing securitizations. These are reported on our consolidated balance sheets within other assets. The carrying amount of liabilities of unconsolidated securitization-related VIEs is comprised of obligations on certain swap agreements associated with the securitization of manufactured housing loans and other obligations. These are reported on our consolidated balance sheets within other liabilities. Securitization-Related VIEs In a securitization transaction, assets from our balance sheet are transferred to a trust we establish, which typically meets the definition of a VIE. Our continuing involvement in the majority of our securitization transactions consists primarily of holding certain retained interests and acting as the primary servicer on certain transactions. We also may have exposure associated with contractual obligations to repurchase previously transferred loans due to breaches of representations and warranties. See “ Note 14—Commitments, Contingencies, Guarantees and Others ” for information related to reserves we have established for our mortgage representation and warranty exposure. The table below presents the securitization-related VIEs in which we had continuing involvement as of March 31, 2016 and December 31, 2015 . Table 6.2: Continuing Involvement in Securitization-Related VIEs Mortgage (Dollars in millions) Credit Card Option- ARM GreenPoint HELOCs GreenPoint Manufactured Housing March 31, 2016: Securities held by third-party investors $ 14,913 $ 1,692 $ 69 $ 765 Receivables in the trust 31,908 1,749 63 771 Cash balance of spread or reserve accounts 0 8 N/A 136 Retained interests Yes Yes Yes Yes Servicing retained Yes Yes (1) No No (2) Amortization event (3) No No No No December 31, 2015: Securities held by third-party investors $ 16,166 $ 1,754 $ 74 $ 789 Receivables in the trust 33,783 1,814 68 794 Cash balance of spread or reserve accounts 0 8 N/A 134 Retained interests Yes Yes Yes Yes Servicing retained Yes Yes (1) No No (2) Amortization event (3) No No No No __________ (1) We continue to service only certain option-ARM securitizations. (2) The core servicing activities for the manufactured housing securitizations are completed by a third party. (3) Amortization events vary according to each specific trust agreement but generally are triggered by declines in performance or credit metrics of the underlying assets, such as net charge-off rates or delinquency rates, beyond certain predetermined thresholds. Generally, the occurrence of an amortization event changes the sequencing and amount of trust-related cash flows to the benefit of more senior interest holders. Credit Card Loan Securitizations We hold certain retained interests in our credit card loan securitizations and continue to service the receivables in these trusts. As of March 31, 2016 and December 31, 2015 , we were deemed to be the primary beneficiary, and accordingly, all of these trusts have been consolidated in our financial statements. Mortgage Securitizations Option-ARM Loans We had previously securitized option-ARM loans by transferring these loans to securitization trusts that had issued mortgage-backed securities to investors. The outstanding balance of debt securities held by third-party investors related to these mortgage loan securitization trusts was $1.7 billion and $1.8 billion as of March 31, 2016 and December 31, 2015 , respectively. We continue to service a portion of the remaining mortgage loans in these securitizations. We also retain rights to future cash flows arising from these securitizations, the most significant being certificated interest-only bonds issued by the trusts. We generally estimate the fair value of these retained interests based on the estimated present value of expected future cash flows, using our best estimates of the key assumptions which include credit losses, prepayment speeds and discount rates commensurate with the risks involved. For the mortgage loans that we continue to service, we do not consolidate the related trusts because we do not have the right to receive benefits nor the obligation to absorb losses that could potentially be significant to the trusts. For the remaining trusts, for which we no longer service the underlying mortgage loans, we do not consolidate these entities since we do not have the power to direct the activities that most significantly impact the economic performance of the trusts. In connection with the securitization of certain option-ARM loans, a third party is obligated to advance a portion of any “negative amortization” resulting from monthly payments that are less than the interest accrued for that payment period. We have an agreement in place with the third party that mirrors this advance requirement. The amount advanced is tracked through mortgage-backed securities retained as part of the securitization transaction. As advances occur, we record an asset in the form of negative amortization bonds, which are held at fair value in other assets on our consolidated balance sheets. Our maximum exposure is affected by rate caps and monthly payment change caps, but the funding obligation cannot exceed the difference between the original loan balance multiplied by a preset negative amortization cap and the current unpaid principal balance. We have also entered into certain derivative contracts related to the securitization activities. These are classified as free-standing derivatives, with fair value adjustments recorded in non-interest income in our consolidated statements of income. See “ Note 9—Derivative Instruments and Hedging Activities ” for further details on these derivatives. GreenPoint Mortgage Home Equity Lines of Credit (“HELOCs”) Our discontinued wholesale mortgage banking unit, GreenPoint, previously sold HELOCs in whole loan sales and subsequently acquired residual interests in certain trusts which securitized some of those loans. We do not consolidate these trusts because we either lack the power to direct the activities that most significantly impact the economic performance of the trusts or because we do not have the right to receive benefits or the obligation to absorb losses that could potentially be significant to the trusts. As the residual interest holder, GreenPoint is required to fund advances on the HELOCs when certain performance triggers are met due to deterioration in asset performance. On behalf of GreenPoint, we have funded cumulative advances of $30 million as of both March 31, 2016 and December 31, 2015 . These advances are generally expensed as funded due to the low likelihood of recovery. We also have unfunded commitments of $6 million related to those interests for our non-consolidated VIEs as of both March 31, 2016 and December 31, 2015 . GreenPoint Credit Manufactured Housing We retain the primary obligation for certain provisions of corporate guarantees, recourse sales and clean-up calls related to the discontinued manufactured housing operations of GreenPoint Credit, LLC, which was a subsidiary of GreenPoint and was sold to a third party in 2004. Although we are the primary obligor, recourse obligations related to aforementioned whole loan sales, commitments to exercise mandatory clean-up calls on certain securitization transactions and servicing were transferred to a third party in the sale transaction. We do not consolidate the trusts used for the securitization of manufactured housing loans because we do not have the power to direct the activities that most significantly impact the economic performance of the trusts since we no longer service the loans. We were required to fund letters of credit in 2004 to cover losses and are obligated to fund future amounts under swap agreements for certain transactions. We have the right to receive any funds remaining in the letters of credit after the securities are released. The unpaid principal balance of manufactured housing securitization transactions where we are the residual interest holder was $771 million and $794 million as of March 31, 2016 and December 31, 2015 , respectively. In the event the third-party servicer does not fulfill its obligation to exercise the clean-up calls on certain transactions, the obligation reverts to us and we would assume approximately $420 million of loans receivable upon our execution of the clean-up call with the requirement to absorb any losses on the loans receivable. We monitor the underlying assets for trends in delinquencies and related losses, and these factors are considered in assessing the adequacy of the liabilities established for these obligations and the valuations of the assets. We also have credit exposure on agreements that we entered into to absorb a portion of the risk of loss on certain manufactured housing securitizations issued by GreenPoint Credit, LLC in 2000. Our maximum credit exposure related to the agreements totaled $13 million as of both March 31, 2016 and December 31, 2015 . These agreements are recorded on our consolidated balance sheets as a component of other liabilities and our obligation under these agreements was $7 million and $8 million as of March 31, 2016 and December 31, 2015 , respectively. Other VIEs Affordable Housing Entities As part of our community reinvestment initiatives, we invest in private investment funds that make equity investments in multi-family affordable housing properties. We receive affordable housing tax credits for these investments. The activities of these entities are financed with a combination of invested equity capital and debt. We account for certain of our investments in qualified affordable housing projects using the proportional amortization method if certain criteria are met. The proportional amortization method amortizes the cost of the investment over the period in which the investor expects to receive tax credits and other tax benefits, and the resulting amortization is recognized as a component of income tax expense attributable to continuing operations. For the three months ended March 31, 2016 and 2015 , we recognized amortization of $98 million and $86 million , respectively, and tax credits of $113 million and $102 million , respectively, associated with these investments within income tax provision. The carrying value of our investments in these qualified affordable housing projects was $3.6 billion and $3.5 billion as of March 31, 2016 and December 31, 2015 , respectively. We are periodically required to provide additional financial or other support during the period of the investments. We had a recorded liability of $1.3 billion for these unfunded commitments as of March 31, 2016 , which is expected to be paid from 2016 to 2019 . For those investment funds considered to be VIEs, we are not required to consolidate them if we do not have the power to direct the activities that most significantly impact the economic performance of those entities. We record our interests in these unconsolidated VIEs in loans held for investment, other assets and other liabilities on our consolidated balance sheets. Our interests consisted of assets of approximately $3.8 billion and $3.9 billion as of March 31, 2016 and December 31, 2015 , respectively. Our maximum exposure to these entities is limited to our variable interests in the entities of $3.8 billion and $3.9 billion as of March 31, 2016 and December 31, 2015 , respectively. The creditors of the VIEs have no recourse to our general credit and we do not provide additional financial or other support other than during the period that we are contractually required to provide it. The total assets of the unconsolidated VIE investment funds were $11.3 billion and $11.4 billion as of March 31, 2016 and December 31, 2015 , respectively. Entities that Provide Capital to Low-Income and Rural Communities We hold variable interests in entities (“Investor Entities”) that invest in community development entities (“CDEs”) that provide debt financing to businesses and non-profit entities in low-income and rural communities. Variable interests in the CDEs held by the consolidated Investor Entities are also our variable interests. The activities of the Investor Entities are financed with a combination of invested equity capital and debt. The activities of the CDEs are financed solely with invested equity capital. We receive federal and state tax credits for these investments. We consolidate the VIEs in which we have the power to direct the activities that most significantly impact the VIE’s economic performance and where we have the obligation to absorb losses or right to receive benefits that could be potentially significant to the VIE. We have also consolidated other investments and CDEs that are not considered to be VIEs, but where we hold a controlling financial interest. The assets of the VIEs that we consolidated, which totaled approximately $687 million and $352 million as of March 31, 2016 and December 31, 2015 , respectively, are reflected on our consolidated balance sheets in cash, loans held for investment, interest receivable and other assets. The liabilities are reflected in other liabilities. The creditors of the VIEs have no recourse to our general credit. We have not provided additional financial or other support other than during the period that we are contractually required to provide it. Other Other VIEs include variable interests that we hold in a trust that has a royalty interest in certain oil and gas properties, alternative energy project companies that promote renewable energy sources and other equity method investments. We were not required to consolidate these entities because we do not have the power to direct the activities that most significantly impact their economic performance. Our maximum exposure to these entities is limited to the investment on our consolidated balance sheet of $116 million and $57 million as of March 31, 2016 and December 31, 2015 , respectively. The creditors of the other VIEs have no recourse to our general credit. We have not provided additional financial or other support other than during the period that we are contractually required to provide it.

Deposits and Borrowings [Abstract]
Deposits and Borrowings	NOTE 8—DEPOSITS AND BORROWINGS Deposits Our deposits, which are our largest source of funding for our asset and operations, consist of non-interest bearing and interest-bearing deposits, which include checking accounts, money market deposit accounts, negotiable order of withdrawals, savings deposits and time deposits. Securitized and Unsecured Debt Obligations In addition to our deposits, which serve as our primary funding source, we use a variety of other funding sources including short-term borrowings, the issuance of senior and subordinated notes and other borrowings, and securitization transactions. In addition, we utilize FHLB advances, which are secured by certain portions of our loan and investment securities portfolios, for our funding needs. The securitized debt obligations are separately presented on our consolidated balance sheets as they represent obligations of consolidated securitization trusts, while federal funds purchased and securities loaned or sold under agreements to repurchase, senior and subordinated notes and other borrowings, including FHLB advances, are included in other debt on our consolidated balance sheets. Securitized Debt Obligations Our outstanding borrowings due to securitization investors decreased to $14.9 billion as of March 31, 2016, from $16.2 billion as of December 31, 2015 , primarily driven by $1.3 billion of maturities. Senior and Subordinated Notes As of March 31, 2016 , we had $21.7 billion of senior and subordinated notes outstanding, inclusive of fair value hedging adjustments of $237 million . As of December 31, 2015 , we had $21.8 billion of senior and subordinated notes outstanding, inclusive of fair value hedging adjustments of $134 million . During the first quarter of 2016 , $500 million of outstanding unsecured notes were retired. See “ Note 9—Derivative Instruments and Hedging Activities ” for information about our fair value hedging activities. FHLB Advances and Other In addition to the issuance capacity under the registration statement, we also have access to funding through the FHLB system and the Federal Reserve Discount Window. Our FHLB and Federal Reserve memberships require us to hold FHLB and Federal Reserve stock which totaled $1.8 billion and $2.1 billion as of March 31, 2016 and December 31, 2015 , respectively, and are included in other assets on our consolidated balance sheets. Our FHLB advances and lines of credit are secured by our investment securities, residential home loans, multifamily real estate loans, commercial real estate loans and HELOCs. The outstanding FHLB advances totaled $12.9 billion and $20.1 billion as of March 31, 2016 and December 31, 2015 , respectively, substantially all of which represented long-term advances generally callable on either a one-month or a three-month basis. We did not access the Federal Reserve Discount Window for funding during 2015 or the first quarter of 2016 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	NOTE 9—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Use of Derivatives We manage our asset and liability positions and market risk exposure and limits in accordance with our market risk management policies that are approved by our Board of Directors. Our primary market risks stem from the impact on our earnings and economic value of equity from changes in interest rates and, to a lesser extent, changes in foreign exchange rates. We employ several techniques to manage our interest rate sensitivity which include changing the duration and re-pricing characteristics of various assets and liabilities by using interest rate derivatives. Our current policies also include the use of derivatives to hedge exposures denominated in foreign currency so we may limit our earnings and capital ratio exposures to foreign exchange risk. We execute our derivative contracts in both the over-the-counter (“OTC”) and exchange-traded derivative markets, and clear eligible derivative transactions through a central clearinghouse as required under the Dodd-Frank Act. The majority of our derivatives are interest rate swaps. In addition, we may use a variety of other derivative instruments, including caps, floors, options, futures and forward contracts, to manage our interest rate and foreign exchange risks. We offer various interest rate, foreign exchange rate and commodity derivatives as an accommodation to our customers within our Commercial Banking business, and usually offset our exposure through derivative transactions with other counterparties. Accounting for Derivatives Our derivatives are designated as either qualifying accounting hedges or free-standing derivatives. Qualifying accounting hedges are designated as fair value hedges, cash flow hedges or net investment hedges. Free-standing derivatives primarily consist of customer-accommodation derivatives and economic hedges that do not qualify for hedge accounting. • Fair Value Hedges: We designate derivatives as fair value hedges when they are used to manage our exposure to changes in the fair value of certain financial assets and liabilities, which fluctuate in value as a result of movements in interest rates. Changes in the fair value of derivatives designated as fair value hedges are recorded in earnings together with offsetting changes in the fair value of the hedged item and any resulting ineffectiveness. Our fair value hedges consist of interest rate swaps that are intended to modify our exposure to interest rate risk on various fixed-rate assets and liabilities. • Cash Flow Hedges: We designate derivatives as cash flow hedges when they are used to manage our exposure to variability in cash flows related to forecasted transactions. Changes in the fair value of derivatives designated as cash flow hedges are recorded as a component of AOCI, to the extent that the hedge relationships are effective, and amounts are reclassified from AOCI to earnings as the forecasted transactions impact earnings. To the extent that any ineffectiveness exists in the hedge relationships, the amounts are recorded in current period earnings. Our cash flow hedges use interest rate swaps and floors that are intended to hedge the variability in interest payments or interest receipts on some of our variable-rate assets or liabilities. We have also entered into forward foreign currency derivative contracts to hedge our exposure to variability in cash flows related to intercompany borrowings denominated in foreign currency. • Net Investment Hedges: We use net investment hedges to manage the foreign currency exposure related to our net investments in foreign operations that have functional currencies other than the U.S. dollar. Changes in the fair value of net investment hedges are recorded in the translation adjustment component of AOCI, offsetting the translation gain or loss from those foreign operations. We execute net investment hedges using foreign exchange forward contracts to hedge the translation exposure of the net investment in our foreign operations. • Free-Standing Derivatives: We use free-standing derivatives to hedge the risk of changes in the fair value of residential MSRs, mortgage loan origination and purchase commitments and other interests held. We also categorize our customer accommodation derivatives and the related offsetting contracts as free-standing derivatives. Changes in the fair value of free-standing derivatives are recorded in earnings as a component of other non-interest income. Balance Sheet Presentation The following table summarizes the notional and fair values of our derivative instruments on a gross basis as of March 31, 2016 and December 31, 2015 , which are segregated by derivatives that are designated as accounting hedges and those that are not, and are further segregated by type of contract within those two categories. The total derivative assets and liabilities are adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements and any associated cash collateral received or paid.

(2) Includes interest rate swaps and to-be-announced contracts. (3) Other interest rate exposures include mortgage-related derivatives. (4) Represents balance sheet netting of derivative assets and liabilities, and related payables and receivables for cash collateral held or placed with the same counterparty. See Table 9.2 for further information. Offsetting of Financial Assets and Liabilities We execute the majority of our derivative transactions and repurchase agreements under master netting arrangements. Under our existing enforceable master netting arrangements, we generally have the right to offset exposure with the same counterparty. In addition, either counterparty can generally request the net settlement of all contracts through a single payment upon default on, or termination of, any one contract. The Company offsets derivative assets and liabilities for purposes of balance sheet presentation where a right of setoff exists. As of March 31, 2016 and December 31, 2015 , derivative contracts that are executed bilaterally with a counterparty in the OTC market and then novated to and cleared through a central clearinghouse are not subject to offsetting due to the uncertainty existing around an end-user’s ability to setoff derivative contracts that have been novated to a clearinghouse. The following table presents as of March 31, 2016 and December 31, 2015 the gross and net fair values of our derivative assets and liabilities and repurchase agreements, as well as the related offsetting amounts permitted under U.S. GAAP. The table also includes cash and non-cash collateral received or pledged associated with such arrangements. The collateral amounts shown are limited to the extent of the related net derivative fair values or outstanding balances, thus instances of over-collateralization are not shown.

The comparable amounts as of December 31, 2015 totaled $429 million and $314 million , respectively. These contracts were not subject to offsetting as of March 31, 2016 and December 31, 2015 . (2) As of March 31, 2016 and December 31, 2015 , the Company only had repurchase obligations outstanding and did not have any reverse repurchase receivables. (3) Represents customer repurchase agreements that mature the next business day. As of March 31, 2016 , we pledged collateral with a fair value of $936 million under these customer repurchase agreements, which were primarily agency RMBS securities. Credit Risk-Related Contingency Features and Collateral Certain of our derivatives contracts include provisions requiring that our debt maintain a credit rating of investment grade or above by each of the major credit rating agencies. In the event of a downgrade of our debt credit rating below investment grade, some of our derivatives counterparties would have the right to terminate the derivative contract and close out the existing positions, or demand immediate and ongoing full overnight collateralization on derivative instruments in a net liability position. Certain of our derivatives contracts may also allow, in the event of a downgrade of our debt credit rating of any kind, our derivatives counterparties to demand additional collateralization on such derivatives instruments in a net liability position. We posted $215 million and $304 million of cash collateral as of March 31, 2016 and December 31, 2015 , respectively. If our debt credit rating had fallen below investment grade, we would have been required to post $60 million and $55 million of additional collateral as of March 31, 2016 and December 31, 2015 , respectively. The fair value of derivatives instruments with credit risk-related contingent features in a net liability position was less than $1 million as of both March 31, 2016 and December 31, 2015 . Derivatives Counterparty Credit Risk Derivatives instruments contain an element of credit risk that arises from the potential failure of a counterparty to perform according to the contractual terms of the contract. Our exposure to derivatives counterparty credit risk, at any point in time, is represented by the fair value of derivatives in a gain position, or derivatives assets position, assuming no recoveries of underlying collateral. To mitigate the risk of counterparty default, we enter into legally enforceable master netting agreements and maintain collateral agreements with certain derivative counterparties. We generally enter into these agreements on a bilateral basis with our counterparties; however, since June 2013 we have begun to clear eligible OTC derivatives through a central clearinghouse in accordance with the requirements under Title VII of the Dodd-Frank Act. These agreements typically provide for the right to offset exposures and require both parties to maintain collateral in the event the fair values of derivative financial instruments exceed established thresholds. We received cash collateral from derivatives counterparties totaling $502 million and $544 million as of March 31, 2016 and December 31, 2015 , respectively. We also received securities from derivatives counterparties with a fair value of $7 million and $172 million as of March 31, 2016 and December 31, 2015 , respectively, which we have the ability to re-pledge. We record counterparty credit risk valuation adjustments on our derivative assets to properly reflect the credit quality of the counterparty. We consider collateral and legally enforceable master netting agreements that mitigate our credit exposure to each counterparty in determining the counterparty credit risk valuation adjustment, which may be adjusted in future periods due to changes in the fair value of the derivatives contracts, collateral and creditworthiness of the counterparty. The cumulative counterparty credit risk valuation adjustment recorded on our consolidated balance sheets as a reduction to the derivatives asset balance was $5 million and $4 million as of March 31, 2016 and December 31, 2015 , respectively. We also adjust the fair value of our derivatives liabilities to reflect the impact of our own credit quality. We calculate this adjustment by comparing the spreads on our credit default swaps to the discount benchmark curve. The cumulative credit risk valuation adjustment related to our credit quality recorded on our consolidated balance sheets as a reduction in the derivative liability balance was less than $1 million as of both March 31, 2016 and December 31, 2015 . Income Statement Presentation and AOCI The following tables summarize the impact of derivatives and the related hedged items in our consolidated statements of income and AOCI. Fair Value Hedges and Free-Standing Derivatives The net gains (losses) recognized in earnings related to derivatives in fair value hedging relationships and free-standing derivatives are presented below for the three months ended March 31, 2016 and 2015 .

(2) Amounts are recorded in our consolidated statements of income in other non-interest income or other interest income. In the next 12 months, we expect to reclassify to earnings net after-tax gains of $173 million currently recorded in AOCI as of March 31, 2016 . These amounts will offset the cash flows associated with the hedged forecasted transactions. The maximum length of time over which forecasted transactions were hedged was approximately six years as of March 31, 2016 . The amount we expect to reclassify into earnings may change as a result of changes in market conditions and ongoing actions taken as part of our overall risk management strategy.

Fair Value Measurement

Fair Value Measurement	Mar. 31, 2016
Fair Value Disclosures [Abstract]
Fair Value Measurement	NOTE 12—FAIR VALUE MEASUREMENT Fair value is defined as the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date (also referred to as an exit price). The fair value accounting guidance provides a three-level fair value hierarchy for classifying financial instruments. This hierarchy is based on the markets in which the assets or liabilities trade and whether the inputs to the valuation techniques used to measure fair value are observable or unobservable. The fair value measurement of a financial asset or liability is assigned a level based on the lowest level of any input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are described below: Level 1: Valuation is based on quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Valuation is based on observable market-based inputs, other than quoted prices in active markets for identical assets or liabilities, quoted prices in markets that are not active, or models using inputs that are observable or can be corroborated by observable market data of substantially the full term of the assets or liabilities. Level 3: Valuation is generated from techniques that use significant assumptions not observable in the market. Valuation techniques include pricing models, discounted cash flow methodologies or similar techniques. The accounting guidance for fair value measurements requires that we maximize the use of observable inputs and minimize the use of unobservable inputs in determining fair value. The accounting guidance provides for the irrevocable option to elect, on a contract-by-contract basis, to measure certain financial assets and liabilities at fair value at inception of the contract and record any subsequent changes in fair value in earnings. We have not made any material fair value option elections as of or for the periods disclosed herein. For additional information on the valuation techniques used in estimating the fair value of our financial assets and liabilities on a recurring or nonrecurring basis and for estimating the fair value for financial instruments that are not recorded at fair value, see “Note 19—Fair Value Measurement” in our 2015 Form 10-K. Fair Value Governance and Control We have a governance framework and a number of key controls that are intended to ensure that our fair value measurements are appropriate and reliable. Our governance framework provides for independent oversight and segregation of duties. Our control processes include review and approval of new transaction types, price verification and review of valuation judgments, methods, models, process controls and results. Groups independent of our trading and investing functions, including our Corporate Valuations Group (“CVG”), Fair Value Committee (“FVC”) and Model Validation Group (“MVG”), participate in the review and validation process. The fair valuation governance process is set up in a manner that allows the Chairperson of the FVC to escalate valuation disputes that cannot be resolved by the FVC to a more senior committee called the Valuations Advisory Committee (“VAC”) for resolution. The VAC is chaired by the Chief Financial Officer and includes other members of senior management. The VAC is only required to convene to review escalated valuation disputes and may meet for a general update on the valuation process. The CVG performs periodic verification of fair value measurements to determine if assigned fair values are reasonable. For example, in cases where we rely on third-party pricing services to obtain fair value measures, we analyze pricing variances among different pricing sources and validate the final price used by comparing the information to additional sources, including dealer pricing indications in transaction results and other internal sources, where necessary. Additional validation procedures performed by the CVG include reviewing (either directly or indirectly through the reasonableness of assigned fair values) valuation inputs and assumptions and monitoring acceptable variances between recommended prices and validation prices. The CVG and the Trade Analytics and Valuation (“TAV”) team perform due diligence reviews of the third-party pricing services by comparing their prices to those from other sources and periodically reviewing research publications. Additionally, when necessary, the CVG and TAV challenge prices from third-party vendors to ensure reasonableness of prices through a pricing challenge process. This may include a request for transparency of the assumptions used by the third party. The FVC, which includes representation from our Risk Management and Finance functions, is a forum for discussing fair market valuations, related inputs, assumptions, methodologies, as well as variance thresholds, valuation control environments and material risks or concerns related to fair market valuations. Additionally, the FVC is empowered to resolve valuation disputes between the primary valuation providers and the CVG, and provides guidance and oversight to ensure an appropriate valuation control environment. The FVC regularly reviews and approves our valuation methodologies to ensure that our methodologies and practices are consistent with industry standards and adhere to regulatory and accounting guidance. The Chief Financial Officer determines when material issues or concerns regarding valuations shall be raised to the Audit Committee or another delegated committee of the Board of Directors. We have a model policy, established by an independent Model Risk Office, which governs the validation of models and related supporting documentation to ensure the appropriate use of models for pricing. The MVG is part of the Model Risk Office and validates all models and provides ongoing monitoring of their performance, including the validation and monitoring of the performance of all valuation models. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table displays our assets and liabilities measured on our consolidated balance sheets at fair value on a recurring basis as of March 31, 2016 and December 31, 2015 : Table 12.1: Assets and Liabilities Measured at Fair Value on a Recurring Basis March 31, 2016 Fair Value Measurements Using (Dollars in millions) Level 1 Level 2 Level 3 Total Assets: Securities available for sale: U.S. Treasury securities $ 4,966 $ 0 $ 0 $ 4,966 RMBS 0 27,763 505 28,268 CMBS 0 5,253 251 5,504 Other ABS 0 1,008 30 1,038 Other securities 303 2 11 316 Total securities available for sale 5,269 34,026 797 40,092 Other assets: Consumer MSRs 0 0 59 59 Derivative assets (1)(2) 2 1,950 71 2,023 Retained interests in securitizations 0 0 201 201 Total assets $ 5,271 $ 35,976 $ 1,128 $ 42,375 Liabilities: Other liabilities: Derivative liabilities (1)(2) $ 3 $ 752 $ 40 $ 795 Total liabilities $ 3 $ 752 $ 40 $ 795 December 31, 2015 Fair Value Measurements Using (Dollars in millions) Level 1 Level 2 Level 3 Total Assets: Securities available for sale: U.S. Treasury securities $ 4,660 $ 0 $ 0 $ 4,660 RMBS 0 26,807 504 27,311 CMBS 0 5,282 97 5,379 Other ABS 0 1,340 0 1,340 Other securities 355 2 14 371 Total securities available for sale 5,015 33,431 615 39,061 Other assets: Consumer MSRs 0 0 68 68 Derivative assets (1)(2) 2 1,459 57 1,518 Retained interests in securitizations 0 0 211 211 Total assets $ 5,017 $ 34,890 $ 951 $ 40,858 Liabilities: Other liabilities: Derivative liabilities (1)(2) $ 2 $ 491 $ 27 $ 520 Total liabilities $ 2 $ 491 $ 27 $ 520 __________ (1) The balances represent gross derivative amounts and are not reduced by the impact of legally enforceable master netting agreements that allow us to net positive and negative positions and the related payables and receivables for cash collateral held or placed with the same counterparty. The net derivative assets were $1.7 billion and $986 million , and the net derivative liabilities were $445 million and $377 million as of March 31, 2016 and December 31, 2015 , respectively. See “ Note 9—Derivative Instruments and Hedging Activities ” for further information. (2) Does not reflect $4 million recognized as a net valuation allowance on derivative assets and liabilities for non-performance risk as of both March 31, 2016 and December 31, 2015 . Non-performance risk is reflected in other assets and liabilities on the consolidated balance sheets and offset through non-interest income in the consolidated statements of income. The determination of the classification of financial instruments in the fair value hierarchy is performed at the end of each reporting period. We consider all available information, including observable market data, indications of market liquidity and orderliness, and our understanding of the valuation techniques and significant inputs. Based upon the specific facts and circumstances of each instrument or instrument category, judgments are made regarding the significance of the unobservable inputs to the instruments’ fair value measurement in its entirety. If unobservable inputs are considered significant, the instrument is classified as Level 3. The process for determining fair value using unobservable inputs is generally more subjective and involves a high degree of management judgment and assumptions. During the three months ended March 31, 2016 , we had minimal movements between Levels 1 and 2. Level 3 Recurring Fair Value Rollforward The table below presents a reconciliation for all assets and liabilities measured and recognized at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2016 and 2015 . When assets and liabilities are transferred between levels, we recognize the transfer as of the end of the period. Table 12.2: Level 3 Recurring Fair Value Rollforward Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Three Months Ended March 31, 2016 Total Gains (Losses) (Realized/Unrealized) Net Unrealized Gains (Losses) Included in Net Income Related to Assets and Liabilities Still Held as of March 31, 2016 (3) (Dollars in millions) Balance, January 1, 2016 Included in Net Income (1) Included in OCI Purchases Sales Issuances Settlements Transfers Into Level 3 (2) Transfers Out of Level 3 (2) Balance, March 31, 2016 Assets: Securities available for sale: RMBS $ 504 $ 6 $ (5 ) $ 0 $ 0 $ 0 $ (17 ) $ 127 $ (110 ) $ 505 $ 6 CMBS 97 0 1 93 0 0 (4 ) 64 0 251 0 Other ABS 0 0 0 30 0 0 0 0 0 30 0 Other securities 14 0 0 0 0 0 (3 ) 0 0 11 0 Total securities available for sale 615 6 (4 ) 123 0 0 (24 ) 191 (110 ) 797 6 Other assets: Consumer MSRs 68 (12 ) 0 0 0 4 (1 ) 0 0 59 (12 ) Derivative assets (4) 57 19 0 0 0 12 (11 ) 0 (6 ) 71 19 Retained interest in securitizations 211 (10 ) 0 0 0 0 0 0 0 201 (10 ) Liabilities: Other liabilities: Derivative liabilities (4) $ (27 ) $ (14 ) $ 0 $ 0 $ 0 $ (7 ) $ 3 $ 0 $ 5 $ (40 ) $ (14 ) Fair Value Measurements Using Significant Unobservable Inputs (Level 3) Three Months Ended March 31, 2015 Total Gains (Losses) (Realized/Unrealized) Net Unrealized Gains (Losses) Included in Net Income Related to Assets and Liabilities Still Held as of March 31, 2015 (3) (Dollars in millions) Balance, January 1, 2015 Included in Net Income (1) Included in OCI Purchases Sales Issuances Settlements Transfers Into Level 3 (2) Transfers Out of Level 3 (2) Balance, March 31, 2015 Assets: Securities available for sale: Corporate debt securities guaranteed by U.S. government agencies $ 333 $ (2 ) $ 5 $ 0 $ (68 ) $ 0 $ (8 ) $ 0 $ (88 ) $ 172 $ 0 RMBS 561 8 8 0 0 0 (13 ) 85 (94 ) 555 9 CMBS 228 0 1 0 0 0 (21 ) 0 (34 ) 174 0 Other ABS 65 1 (2 ) 0 (20 ) 0 0 0 (37 ) 7 0 Other securities 18 0 0 0 0 0 0 0 0 18 0 Total securities available for sale 1,205 7 12 0 (88 ) 0 (42 ) 85 (253 ) 926 9 Other assets: Consumer MSRs 53 (3 ) 0 0 0 4 (1 ) 0 0 53 (3 ) Derivative assets (4) 66 11 0 0 0 9 (12 ) 0 (1 ) 73 11 Retained interest in securitization 221 2 0 0 0 0 0 0 0 223 2 Liabilities: Other liabilities: Derivative liabilities (4) $ (43 ) $ (10 ) $ 0 $ 0 $ 0 $ (7 ) $ 12 $ 0 $ 0 $ (48 ) $ (10 ) __________ (1) Gains (losses) related to Level 3 Consumer MSRs, derivative assets and derivative liabilities, and retained interests in securitizations are reported in other non-interest income, which is a component of non-interest income, in our consolidated statements of income. (2) During the three months ended March 31, 2016 and 2015 , the transfers into Level 3 were primarily driven by less consistency among vendor pricing on individual securities, while the transfers out of Level 3 were primarily driven by greater consistency among multiple pricing sources. (3) The amount presented for unrealized gains (losses) for assets still held as of the reporting date primarily represents impairments of securities available for sale, accretion on certain fixed maturity securities, changes in fair value of derivative instruments and mortgage servicing rights transactions. Impairment is reported in total OTTI, which is a component of non-interest income, in our consolidated statements of income. (4) All Level 3 derivative assets and liabilities are presented on a gross basis and are not reduced by the impact of legally enforceable master netting agreements that allow us to net positive and negative positions and the related payables and receivables for cash collateral held or placed with the same counterparty. Significant Level 3 Fair Value Asset and Liability Input Sensitivity Changes in unobservable inputs may have a significant impact on fair value. Certain of these unobservable inputs will, in isolation, have a directionally consistent impact on the fair value of the instrument for a given change in that input. Alternatively, the fair value of the instrument may move in an opposite direction for a given change in another input. In general, an increase in the discount rate, default rates, loss severity and credit spreads, in isolation, would result in a decrease in the fair value measurement. In addition, an increase in default rates would generally be accompanied by a decrease in recovery rates, slower prepayment rates and an increase in liquidity spreads. Techniques and Inputs for Level 3 Fair Value Measurements The following table presents the significant unobservable inputs relied upon to determine the fair values of our Level 3 financial instruments on a recurring basis. We utilize multiple third-party pricing services to obtain fair value measures for our securities. Several of our third-party pricing services are only able to provide unobservable input information for a limited number of securities due to software licensing restrictions. Other third-party pricing services are able to provide unobservable input information for all securities for which they provide a valuation. As a result, the unobservable input information for the securities available for sale presented below represents a composite summary of all information we are able to obtain for a majority of our securities. The unobservable input information for all other Level 3 financial instruments is based on the assumptions used in our internal valuation models. Table 12.3: Quantitative Information about Level 3 Fair Value Measurements Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at March 31, Significant Valuation Techniques Significant Unobservable Inputs Range Weighted Average Assets: Securities available for sale: RMBS $ 505 Discounted cash flows (3rd party pricing) Yield 0-15% 6% CMBS 251 Discounted cash flows (3rd party pricing) Yield 1-3% 2% Other ABS 30 Discounted cash flows (3rd party pricing) Yield 1% 1% Other securities 11 Discounted cash flows Yield 1% 1% Other assets: Consumer MSRs 59 Discounted cash flows Total prepayment rate 10-20% 17% Derivative assets (1) 71 Discounted cash flows Swap rates 2% 2% Retained interests in securitization (2) 201 Discounted cash flows Life of receivables (months) Constant prepayment rate 14-83 N/A Liabilities: Derivative liabilities (1) $ 40 Discounted cash flows Swap rates 2% 2% Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at December 31, 2015 Significant Valuation Techniques Significant Unobservable Inputs Range Weighted Average Assets: Securities available for sale: RMBS $ 504 Discounted cash flows (3rd party pricing) Yield 0-12% 6% CMBS 97 Discounted cash flows (3rd party pricing) Yield 2-3% 3% Other securities 14 Discounted cash flows Yield 1% 1% Other assets: Consumer MSRs 68 Discounted cash flows Total prepayment rate 11-18% 16% Derivative assets (1) 57 Discounted cash flows Swap rates 2% 2% Retained interests in securitization (2) 211 Discounted cash flows Life of receivables (months) Constant prepayment rate 16-75 N/A Liabilities: Derivative liabilities (1) $ 27 Discounted cash flows Swap rates 2% 2% __________ (1) All Level 3 derivative assets and liabilities are presented on a gross basis and are not reduced by the impact of legally enforceable master netting agreements that allow us to net positive and negative positions and the related payables and receivables for cash collateral held or placed with the same counterparty. (2) Due to the nature of the various mortgage securitization structures in which we have retained interests, it is not meaningful to present a consolidated weighted average for the significant unobservable inputs. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis We are required to measure and recognize certain other assets at fair value on a nonrecurring basis on the consolidated balance sheets. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, from the application of lower of cost or market accounting or when we evaluate for impairment). The following table presents the carrying amount of the assets measured at fair value on a nonrecurring basis and still held as of March 31, 2016 and December 31, 2015 , and for which a nonrecurring fair value measurement was recorded during the three and twelve months then ended: Table 12.4: Nonrecurring Fair Value Measurements Related to Assets Still Held at Period End March 31, 2016 Estimated Fair Value Hierarchy Total (Dollars in millions) Level 1 Level 2 Level 3 Loans held for investment $ 0 $ 0 $ 716 $ 716 Loans held for sale 0 6 0 6 Other assets (1) 0 0 39 39 Total $ 0 $ 6 $ 755 $ 761 December 31, 2015 Estimated Fair Value Hierarchy Total (Dollars in millions) Level 1 Level 2 Level 3 Loans held for investment $ 0 $ 0 $ 362 $ 362 Loans held for sale 0 149 0 149 Other assets (1) 0 0 92 92 Total $ 0 $ 149 $ 454 $ 603 __________ (1) Includes foreclosed property and repossessed assets of $39 million and long-lived assets held for sale of $0 million as of March 31, 2016 , compared to foreclosed property and repossessed assets of $54 million and long-lived assets held for sale of $38 million as of December 31, 2015 . In the above table, loans held for investment primarily include nonperforming loans for which specific reserves or charge-offs have been recognized. These loans are classified as Level 3 as they are valued based in part on the estimated fair value of the underlying collateral and the non-recoverable rate, which is considered to be a significant unobservable input. Collateral fair value sources include the appraisal value obtained from independent appraisers, broker pricing opinions or other available market information. The non-recoverable rate ranged from 0% to 78% , with a weighted average of 11% , and from 9% to 73% , with a weighted average of 20% , as of March 31, 2016 and December 31, 2015 , respectively. The fair value of the other assets classified as Level 3 is determined based on appraisal value or listing price which involves significant judgment; the significant unobservable inputs and related quantitative information are not meaningful to disclose as they vary significantly across properties and collateral. The following table presents total nonrecurring fair value measurements for the period, included in earnings, attributable to the change in fair value relating to assets that are still held at March 31, 2016 and 2015 : Table 12.5: Nonrecurring Fair Value Measurements Included in Earnings Related to Assets Still Held at Period End Total Gains (Losses) Three Months Ended March 31, (Dollars in millions) 2016 2015 Loans held for investment $ (71 ) $ (5 ) Loans held for sale 0 0 Other assets (1) (4 ) (4 ) Total $ (75 ) $ (9 ) __________ (1) Includes losses related to foreclosed property and repossessed assets.

Segment Reporting [Abstract]
Business Segments	NOTE 13—BUSINESS SEGMENTS Our principal operations are currently organized into three major business segments, which are defined based on the products and services provided or the type of customer served: Credit Card, Consumer Banking and Commercial Banking. The operations of acquired businesses have been integrated into our existing business segments. Certain activities that are not part of a segment, such as management of our corporate investment portfolio and asset/liability management by our centralized Corporate Treasury group, are included in the Other category. Basis of Presentation We report the results of each of our business segments on a continuing operations basis. See “ Note 2—Discontinued Operations ” for a discussion of our discontinued operations. The results of our individual businesses reflect the manner in which management evaluates performance and makes decisions about funding our operations and allocating resources. Business Segment Reporting Methodology The results of our business segments are intended to present each segment as if it were a stand-alone business. Our internal management and reporting process used to derive our segment results employs various allocation methodologies, including funds transfer pricing, to assign certain balance sheet assets, deposits and other liabilities and their related revenue and expenses directly or indirectly attributable to each business segment. Our funds transfer pricing process provides a funds credit for sources of funds, such as deposits generated by our Consumer Banking and Commercial Banking businesses, and a funds charge for the use of funds by each segment. Due to the integrated nature of our business segments, estimates and judgments have been made in allocating certain revenue and expense items. Transactions between segments are based on specific criteria or approximate third-party rates. We regularly assess the assumptions, methodologies and reporting classifications used for segment reporting, which may result in the implementation of refinements or changes in future periods. We provide additional information on the allocation methodologies used to derive our business segment results in “Note 20—Business Segments” in our 2015 Form 10-K Segment Results and Reconciliation We may periodically change our business segments or reclassify business segment results based on modifications to our management reporting methodologies and changes in organizational alignment. The following tables present our business segment results for the three months ended March 31, 2016 and 2015 , selected balance sheet data as of March 31, 2016 and 2015 , and a reconciliation of our total business segment results to our reported consolidated income from continuing operations, assets and deposits.

Accordingly, we make certain reclassifications within our Commercial Banking business results to present revenues and yields on a taxable-equivalent basis, calculated assuming an effective tax rate approximately equal to our federal statutory tax rate of 35% with offsetting reclassifications to the Other category.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies, Guarantees, and Others	NOTE 14—COMMITMENTS, CONTINGENCIES, GUARANTEES AND OTHERS Letters of Credit and Loss Sharing Agreements We issue letters of credit (financial standby, performance standby and commercial) to meet the financing needs of our customers. Standby letters of credit are conditional commitments issued by us to guarantee the performance of a customer to a third party in a borrowing arrangement. Commercial letters of credit are short-term commitments issued primarily to facilitate trade finance activities for customers and are generally collateralized by the goods being shipped to the client. These collateral requirements are similar to those for funded transactions and are established based on management’s credit assessment of the customer. Management conducts regular reviews of all outstanding letters of credit and customer acceptances, and the results of these reviews are considered in assessing the adequacy of our allowance for loan and lease losses. Within our Commercial Banking business, we originate multifamily commercial real estate loans with the intent to sell them to a government-sponsored enterprise (“GSE”). We enter into loss sharing agreements with the GSE upon the sale of the loans. At inception, we record a liability representing the fair value of our obligation which is subsequently amortized as we are released from risk of payment under the loss sharing agreement. If payment under the loss sharing agreement becomes probable and estimable, an additional liability may be recorded on the consolidated balance sheets and a non-interest expense may be recognized in the consolidated statements of income. The amount of liability recognized on our consolidated balance sheets for our loss sharing agreements was $41 million and $40 million as of March 31, 2016 and December 31, 2015 , respectively. We had standby letters of credit and commercial letters of credit with contractual amounts of $1.9 billion as of both March 31, 2016 and December 31, 2015 . The carrying value of outstanding letters of credit, which we include in other liabilities on our consolidated balance sheets was $3 million as of both March 31, 2016 and December 31, 2015 . These financial guarantees had expiration dates ranging from 2016 to 2025 as of March 31, 2016 . U.K. Cross Sell In the U.K., we previously sold payment protection insurance (“PPI”) and other ancillary cross sell products. In response to an elevated level of customer complaints across the industry, heightened media coverage and pressure from consumer advocacy groups, the U.K. Financial Conduct Authority (“FCA”), formerly the Financial Services Authority, investigated and raised concerns about the way the industry has handled complaints related to the sale of these insurance policies. For the past several years, the U.K.’s Financial Ombudsman Service (“FOS”) has been adjudicating customer complaints relating to PPI, escalated to it by consumers who disagree with the rejection of their complaint by firms, leading to customer remediation payments by us and others within the industry. On October 2, 2015, the FCA issued a Statement on PPI (“FCA Proposal”) announcing it has decided to consult, by the end of 2015, on the introduction of a time bar for PPI complaints and on new rules and guidance about how banks should handle PPI complaints covered by s.140A of the Consumer Credit Act of 1974 (“Consumer Credit Act”) in light of the U.K. Supreme Court’s 2014 ruling in Plevin v. Paragon Personal Finance Limited (“Plevin”). The industry consultation period ended in February 2016, and we expect the FCA to issue final rules later this year. In determining our best estimate of incurred losses for future remediation payments, management considers numerous factors, including: (i) the number of customer complaints we expect in the future; (ii) our expectation of upholding those complaints; (iii) the expected number of complaints customers escalate to the FOS; (iv) our expectation of the FOS upholding such escalated complaints; (v) the number of complaints that fall under the s.140A of the Consumer Credit Act; and (vi) the estimated remediation payout to customers. We monitor these factors each quarter and adjust our reserves to reflect the latest data. Management’s best estimate of incurred losses related to U.K. cross sell products, including PPI, totaled $150 million and $176 million as of March 31, 2016 and December 31, 2015 , respectively. The decrease to the reserve for the three months ended March 31, 2016 was a combination of utilization of the reserve through customer refund payments and foreign exchange movements. Our best estimate of reasonably possible future losses beyond our reserve as of March 31, 2016 is approximately $250 million . Mortgage Representation and Warranty Liabilities We acquired three subsidiaries that originated residential mortgage loans and sold these loans to various purchasers, including purchasers who created securitization trusts. These subsidiaries are Capital One Home Loans, LLC, which was acquired in February 2005; GreenPoint, which was acquired in December 2006 as part of the North Fork acquisition; and CCB, which was acquired in February 2009 and subsequently merged into CONA (collectively, the “subsidiaries”). In connection with their sales of mortgage loans, the subsidiaries entered into agreements containing varying representations and warranties about, among other things, the ownership of the loan, the validity of the lien securing the loan, the loan’s compliance with any applicable loan criteria established by the purchaser, including underwriting guidelines and the existence of mortgage insurance, and the loan’s compliance with applicable federal, state and local laws. The representations and warranties do not address the credit performance of the mortgage loans, but mortgage loan performance often influences whether a claim for breach of representation and warranty will be asserted and has an effect on the amount of any loss in the event of a breach of a representation or warranty. Each of these subsidiaries may be required to repurchase mortgage loans in the event of certain breaches of these representations and warranties. In the event of a repurchase, the subsidiary is typically required to pay the unpaid principal balance of the loan together with interest and certain expenses (including, in certain cases, legal costs incurred by the purchaser and/or others). The subsidiary then recovers the loan or, if the loan has been foreclosed, the underlying collateral. The subsidiary is exposed to any losses on the repurchased loans, taking into account any recoveries on the collateral. In some instances, rather than repurchase the loans, a subsidiary may agree to make cash payments to make an investor whole on losses or to settle repurchase claims, possibly including claims for attorneys’ fees and interest. In addition, our subsidiaries may be required to indemnify certain purchasers and others against losses they incur as a result of certain breaches of representations and warranties. These subsidiaries, in total, originated and sold to non-affiliates approximately $111 billion original principal balance of mortgage loans between 2005 and 2008, which are the years (or “vintages”) with respect to which our subsidiaries have received the vast majority of the repurchase-related requests and other related claims. The following table presents the original principal balance of mortgage loan originations, by vintage for 2005 through 2008, for the three general categories of purchasers of mortgage loans and the estimated unpaid principal balance as of March 31, 2016 and December 31, 2015 : Table 14.1: Unpaid Principal Balance of Mortgage Loans Originated and Sold to Third Parties Based on Category of Purchaser Estimated Unpaid Principal Balance Original Principal Balance (Dollars in billions) March 31, December 31, Total 2008 2007 2006 2005 GSEs $ 2 $ 2 $ 11 $ 1 $ 4 $ 3 $ 3 Insured Securitizations 3 4 20 0 2 8 10 Uninsured Securitizations and Other 14 14 80 3 15 30 32 Total $ 19 $ 20 $ 111 $ 4 $ 21 $ 41 $ 45 Between 2005 and 2008, our subsidiaries sold an aggregate amount of $11 billion in original principal balance mortgage loans to the GSEs. Of the $20 billion in original principal balance of mortgage loans sold directly by our subsidiaries to private-label purchasers who placed the loans into securitizations supported by bond insurance (“Insured Securitizations”), approximately 48% of the original principal balance was covered by bond insurance. Further, approximately $16 billion original principal balance was placed in securitizations as to which the monoline bond insurers have made repurchase-related requests or loan file requests to one of our subsidiaries (“Active Insured Securitizations”) and the remaining approximately $4 billion original principal balance was placed in securitizations as to which the monoline bond insurers have not made repurchase-related requests or loan file requests to one of our subsidiaries (“Inactive Insured Securitizations”). Insured Securitizations often allow the monoline bond insurer to act independently of the investors. Bond insurers typically have indemnity agreements directly with both the mortgage originators and the securitizers, and they often have super-majority rights within the trust documentation that allow them to direct trustees to pursue mortgage repurchase-related requests without coordination with other investors. Because we do not service most of the loans our subsidiaries sold to others, we do not have complete information about the current ownership of a portion of the $80 billion in original principal balance of mortgage loans not sold directly to GSEs or placed in Insured Securitizations. We have determined based on information obtained from third-party databases that about $48 billion original principal balance of these mortgage loans was placed in private-label publicly issued securitizations not supported by bond insurance (“Uninsured Securitizations”). An additional approximately $22 billion original principal balance of mortgage loans were initially sold to private investors as whole loans. Various known and unknown investors purchased the remaining $10 billion original principal balance of mortgage loans. With respect to the $111 billion in original principal balance of mortgage loans originated and sold to others between 2005 and 2008, we estimate that approximately $19 billion in unpaid principal balance remains outstanding as of March 31, 2016 , of which approximately $3 billion in unpaid principal balance is at least 90 days delinquent. Approximately $22 billion in losses have been realized by third parties. Because we do not service most of the loans we sold to others, we do not have complete information about the underlying credit performance levels for some of these mortgage loans. These amounts reflect our best estimates, including extrapolations of underlying credit performance where necessary. These estimates could change as we get additional data or refine our analysis. The subsidiaries had open repurchase-related requests with regard to approximately $1.4 billion original principal balance of mortgage loans as of March 31, 2016 , flat from December 31, 2015 . Currently, repurchase-related demands predominantly relate to the 2006 and 2007 vintages. We have received relatively few repurchase-related demands from the 2008 and 2009 vintages, mostly because GreenPoint ceased originating mortgages in August 2007. The following table presents information on pending repurchase-related requests by counterparty category and timing of initial request. The amounts presented are based on original loan principal balances. Table 14.2: Open Pipeline All Vintages (All Entities) (1) (Dollars in millions) GSEs Insured Securitizations Uninsured Securitizations and Other Total Open claims as of December 31, 2014 $ 16 $ 649 $ 1,847 $ 2,512 Gross new demands received 23 0 23 46 Loans repurchased/made whole (17 ) 0 (1 ) (18 ) Demands rescinded (21 ) (115 ) (1,054 ) (1,190 ) Open claims as of December 31, 2015 1 534 815 1,350 Gross new demands received 8 0 5 13 Loans repurchased/made whole (1 ) 0 0 (1 ) Demands rescinded (2 ) 0 0 (2 ) Open claims as of March 31, 2016 $ 6 $ 534 $ 820 $ 1,360 __________ (1) The open pipeline includes all timely repurchase-related requests ever received by our subsidiaries where the requesting party has not formally rescinded the repurchase-related request or our subsidiary has not agreed to either repurchase the loan at issue or make the requesting party whole with respect to its losses. The demands rescinded in 2015 reflect the ruling from New York’s highest court in June 2015 that the statute of limitations for repurchase claims begins when the relevant representations and warranties were made, as opposed to some later date during the life of the loan. Finally, the amounts reflected in this chart are the original principal balance amounts of the mortgage loans at issue and do not correspond to the losses our subsidiary would incur upon the repurchase of these loans. The following table summarizes changes in our representation and warranty reserve for the three months ended March 31, 2016 and 2015 : Table 14.3: Changes in Representation and Warranty Reserve (1) Three Months Ended March 31, (Dollars in millions) 2016 2015 Representation and warranty reserve, beginning of period $ 610 $ 731 Provision (benefit) for mortgage representation and warranty losses: Recorded in continuing operations (1 ) 1 Recorded in discontinued operations 3 (19 ) Total provision (benefit) for mortgage representation and warranty losses 2 (18 ) Net realized recoveries (losses) 1 (40 ) Representation and warranty reserve, end of period $ 613 $ 673 __________ (1) Reported on our consolidated balance sheets as a component of other liabilities. The following table summarizes the allocation of our representation and warranty reserve as of March 31, 2016 and 2015 : Table 14.4: Allocation of Representation and Warranty Reserve Reserve Liability Loans Sold 2005 to 2008 (1) (Dollars in millions, except for loans sold) March 31, December 31, Selected period-end data: Active Insured Securitizations and GSEs $ 482 $ 480 $ 27 Inactive Insured Securitizations and Others 131 130 84 Total (2) $ 613 $ 610 $ 111 __________ (1) Reflects, in billions, the total original principal balance of loans originated by our subsidiaries and sold to third-party investors between 2005 and 2008. (2) The total reserve liability includes an immaterial amount related to loans that were originated after 2008. We established reserves for the $11 billion original principal balance of GSE loans, based on open claims and historic repurchase rates. We have entered into and completed repurchase or settlement agreements with respect to the majority of our repurchase exposure within this category. Our reserves could also be impacted by any claims which may be brought by governmental agencies under the Financial Institutions Reform, Recovery and Enforcement Act (“FIRREA”), the False Claims Act or other federal or state statutes. For example, GreenPoint and Capital One have received requests for information and/or subpoenas from various governmental regulators and law enforcement authorities, including members of the RMBS Working Group, relating to the origination of loans for sale to the GSEs and to RMBS participants. We are cooperating with these regulators and other authorities in responding to such requests. For the $16 billion original principal balance in Active Insured Securitizations, our reserving approach is based upon the expected resolution of litigation with the monoline bond insurers. Accordingly, our representation and warranty reserves for this category are litigation reserves. In establishing litigation reserves for this category, we consider the current and future monoline insurer losses inherent within the securitization and apply legal judgment to the developing factual and legal record to estimate the liability for each securitization. We consider as factors within the analysis our own past monoline settlements in addition to publicly available industry monoline settlements. Our reserves with respect to the U.S. Bank Litigation, referenced below, are contained within the Active Insured Securitization reserve category. Further, to the extent we have litigation reserves with respect to indemnification risks from certain representation and warranty lawsuits brought by monoline bond insurers against third-party securitizations sponsors, where one of our subsidiaries provided some or all of the mortgage collateral within the securitization but is not a defendant in the litigation, such reserves are also contained within this category. For the $4 billion original principal balance of mortgage loans in the Inactive Insured Securitizations category and the $48 billion original principal balance of mortgage loans in the Uninsured Securitizations category, we establish reserves based on an assessment of probable and estimable legal liability, if any, utilizing both our own experience and publicly available industry settlement information to estimate lifetime liability. In contrast with the bond insurers in the Insured Securitizations, investors in Uninsured Securitizations often face a number of legal and logistical hurdles before they can force a securitization trustee to pursue mortgage repurchases, including the need to coordinate with a certain percentage of investors holding the securities and to indemnify the trustee for any litigation it undertakes. Accordingly, we only reserve for such exposures when a trustee or investor with standing brings claims and it is probable we have incurred a loss. Some Uninsured Securitization investors from this category are currently suing investment banks and securitization sponsors under federal and/or state securities laws. Although we face some indirect indemnity risks from these litigations, we generally have not established reserves with respect to these indemnity risks because we do not consider them to be both probable and reasonably estimable liabilities. In addition, to the extent we have litigation reserves with respect to indemnification risks from certain representation and warranty lawsuits brought by parties who purchased loans from our subsidiaries and subsequently re-sold the loans into securitizations, such reserves are also contained within this category. For the $22 billion original principal balance of mortgage loans sold to private investors as whole loans, we establish reserves based on open claims and historical repurchase rates. The aggregate reserve for all three subsidiaries totaled $613 million as of March 31, 2016 , compared to $610 million as of December 31, 2015 . We recorded a net loss for mortgage representation and warranty losses of $2 million (which includes a benefit of $1 million before taxes in continuing operations and a loss of $3 million before taxes in discontinued operations) in the first quarter of 2016 . As part of our business planning processes, we have considered various outcomes relating to the future representation and warranty liabilities of our subsidiaries that are possible but do not rise to the level of being both probable and reasonably estimable outcomes justifying an incremental accrual under applicable accounting standards. Our current best estimate of reasonably possible future losses from representation and warranty claims beyond our reserves as of March 31, 2016 is approximately $1.5 billion , a decrease from our $1.6 billion estimate at December 31, 2015 . The decrease in this estimate was primarily driven by favorable rulings in representation and warranty-related litigation. The estimate as of March 31, 2016 covers all reasonably possible losses relating to representation and warranty claim activity, including those relating to the cases more specifically described below in Mortgage Repurchase Litigation. In estimating reasonably possible future losses in excess of our current reserves, we assume a portion of the inactive securitizations become active and for all Insured Securitizations, we assume loss rates on the high end of those observed in monoline settlements or court rulings. For our remaining GSE exposures, Uninsured Securitizations and whole loan exposures, our reasonably possible risk estimates assume lifetime loss rates and claims rates at the highest levels of our past experience and also consider the limited instances of observed settlements. We do not assume claim rates or loss rates for these risk categories will be as high as those assumed for the Active Insured Securitizations, however, based on industry precedent. Should the number of claims or the loss rates on these claims increase significantly, our estimate of reasonably possible risk would increase materially. We also assume that repurchase-related requests will be resolved at discounts reflecting the nature of the claims, the vintage of the underlying loans and evolving legal precedents. Notwithstanding our ongoing attempts to estimate a reasonably possible amount of future losses beyond our current accrual levels based on current information, it is possible that actual future losses will exceed both the current accrual level and our current estimate of the amount of reasonably possible losses. Our reserve and reasonably possible estimates involve considerable judgment and reflect that there is still significant uncertainty regarding numerous factors that may impact the ultimate loss levels, including, but not limited to: litigation outcomes; court rulings; governmental enforcement decisions; future repurchase and indemnification claim levels; securitization trustees pursuing mortgage repurchase litigation unilaterally or in coordination with investors; investors successfully pursuing repurchase litigation independently and without the involvement of the trustee as a party; ultimate repurchase and indemnification rates; future mortgage loan performance levels; actual recoveries on the collateral; and macroeconomic conditions (including unemployment levels and housing prices). In light of the significant uncertainty as to the ultimate liability our subsidiaries may incur from these matters, an adverse outcome in one or more of these matters could be material to our results of operations or cash flows for any particular reporting period. Litigation In accordance with the current accounting standards for loss contingencies, we establish reserves for litigation related matters that arise from the ordinary course of our business activities when it is probable that a loss associated with a claim or proceeding has been incurred and the amount of the loss can be reasonably estimated. None of the amounts we currently have recorded individually or in the aggregate are considered to be material to our financial condition. Litigation claims and proceedings of all types are subject to many uncertain factors that generally cannot be predicted with assurance. Below we provide a description of potentially material legal proceedings and claims. For some of the matters disclosed below, we are able to determine estimates of potential future outcomes that are not probable and reasonably estimable outcomes justifying either the establishment of a reserve or an incremental reserve build, but which are reasonably possible outcomes. For other disclosed matters, such an estimate is not possible at this time. For those matters below where an estimate is possible (excluding the reasonably possible future losses relating to the U.S. Bank Litigation, the FHFA Litigation, and the LXS Trust Litigation, because reasonably possible losses with respect to those litigations are included within the reasonably possible representation and warranty liabilities discussed above) management currently estimates the reasonably possible future losses beyond our reserves as of March 31, 2016 is approximately $200 million . Notwithstanding our attempt to estimate a reasonably possible range of loss beyond our current accrual levels for some litigation matters based on current information, it is possible that actual future losses will exceed both the current accrual level and the range of reasonably possible losses disclosed here. Given the inherent uncertainties involved in these matters, especially those involving governmental actors, and the very large or indeterminate damages sought in some of these matters, there is significant uncertainty as to the ultimate liability we may incur from these litigation matters and an adverse outcome in one or more of these matters could be material to our results of operations or cash flows for any particular reporting period. Interchange Litigation In 2005, a number of entities, each purporting to represent a class of retail merchants, filed antitrust lawsuits (“Interchange Lawsuits”) against MasterCard and Visa and several member banks, including our subsidiaries and us, alleging among other things, that the defendants conspired to fix the level of interchange fees. The complaints seek injunctive relief and civil monetary damages, which could be trebled. Separately, a number of large merchants have asserted similar claims against Visa and MasterCard only. In October 2005, the class and merchant Interchange Lawsuits were consolidated before the U.S. District Court for the Eastern District of New York for certain purposes, including discovery. In July 2012, the parties executed and filed with the court a Memorandum of Understanding agreeing to resolve the litigation on certain terms set forth in a settlement agreement attached to the Memorandum. The class settlement provides for, among other things, (i) payments by defendants to the class and individual plaintiffs totaling approximately $6.6 billion ; (ii) a distribution to the class merchants of an amount equal to 10 basis points of certain interchange transactions for a period of eight months ; and (iii) modifications to certain Visa and MasterCard rules regarding point of sale practices. In December 2013, the court granted final approval of the proposed class settlement, which was appealed to the Second Circuit Court of Appeals in January 2014 and argued before the court on September 28, 2015. Several merchant plaintiffs have also opted out of the class settlement, some of which have sued MasterCard, Visa and various member banks, including Capital One. The opt-out cases were consolidated before the U.S. District Court for the Eastern District of New York for certain purposes, including discovery. These consolidated cases are in their preliminary stages, and Visa and MasterCard have settled a number of individual opt-out cases, requiring non-material payments from all banks. Separate settlement and judgment sharing agreements between Capital One and MasterCard and Visa allocate the liabilities of any judgment or settlement arising from the Interchange Lawsuits and associated opt-out cases. Visa created a litigation escrow account following its IPO of stock in 2008, which funds any settlements for its member banks, and any settlements related to MasterCard allocated losses are reflected in Capital One’s reserves. Mortgage Repurchase Litigation In February 2009, GreenPoint was named as a defendant in a lawsuit commenced in the New York County Supreme Court, by U.S. Bank, N. A., Syncora Guarantee Inc. and CIFG Assurance North America, Inc. (“U.S. Bank Litigation”). Plaintiffs allege, among other things, that GreenPoint breached certain representations and warranties in two contracts pursuant to which GreenPoint sold approximately 30,000 mortgage loans having an aggregate original principal balance of approximately $ 1.8 billion to a purchaser that ultimately transferred most of these mortgage loans to a securitization trust. Some of the securities issued by the trust were insured by Syncora and CIFG. Plaintiffs seek unspecified damages and an order compelling GreenPoint to repurchase the entire portfolio of 30,000 mortgage loans based on alleged breaches of representations and warranties relating to a limited sampling of loans in the portfolio, or, alternatively, the repurchase of specific mortgage loans to which the alleged breaches of representations and warranties relate. In March 2010, the court granted GreenPoint’s motion to dismiss with respect to plaintiffs Syncora and CIFG and denied the motion with respect to U.S. Bank. GreenPoint subsequently answered the complaint with respect to U.S. Bank, denying the allegations, and filed a counterclaim against U.S. Bank alleging breach of covenant of good faith and fair dealing. In February 2012, the court denied plaintiffs’ motion for leave to file an amended complaint and dismissed Syncora and CIFG from the case. Syncora and CIFG appealed their dismissal to the New York Supreme Court, Appellate Division, First Department (“First Department”), which affirmed the dismissal in April 2013. The New York Court of Appeals denied Syncora’s and CIFG’s motion for leave to appeal the First Department’s decision in February 2014. Therefore, the case is now proceeding with U.S. Bank as the sole plaintiff. On May 20, 2015, Lehman Brothers Holding, Inc. (“LBHI”) filed an adversary proceeding in the United States Bankruptcy Court for the Southern District of New York against U.S. Bank, Syncora, and GreenPoint regarding bankruptcy proofs of claims filed by U.S. Bank and Syncora on the same securitization at issue in the U.S. Bank Litigation. In May, June, and July 2012, FHFA (acting as conservator for Freddie Mac) filed three summonses with notice in the New York state court against GreenPoint, on behalf of the trustees for three RMBS trusts backed by loans originated by GreenPoint with an aggregate original principal balance of $3.4 billion . In January 2013, the plaintiffs filed an amended consolidated complaint in the name of the three trusts, acting by the respective trustees, alleging breaches of contractual representations and warranties regarding compliance with GreenPoint underwriting guidelines relating to certain loans (“FHFA Litigation”). Plaintiffs seek specific performance of the repurchase obligations with respect to the loans for which they have provided notice of alleged breaches as well as all other allegedly breaching loans, rescissory damages, indemnification, costs and interest. In July 2013, Lehman XS Trust, Series 2006-4N, by its trustee U.S. Bank, N.A. filed a lawsuit in the Southern District of New York against GreenPoint alleging breaches of representations and warranties made in certain loan sale agreements, pursuant to which GreenPoint sold mortgage loans with an original principal balance of $915 million to Lehman Brothers for securitization and sale to investors. The lawsuit (“LXS Trust Litigation”) seeks specific performance of GreenPoint’s obligation to repurchase certain allegedly breaching loans, or in the alternative, the repurchase of all loans in the trust, the award of rescissory damages, costs, fees and interest. In January 2014, the court granted GreenPoint’s motion to dismiss based on the statute of limitations, which the Second Circuit Court of Appeals affirmed in March 2016. As noted above in the section entitled Mortgage Representation and Warranty Liabilities, the Company’s subsidiaries establish reserves with respect to representation and warranty litigation matters, where appropriate, within the Company’s overall representation and warranty reserves. Please see above for more details. Anti-Money Laundering Capital One has received subpoenas and requests for testimony from the New York District Attorney’s Office (“NYDA”) with respect to certain former check casher clients of the Commercial Banking business and Capital One’s anti-money laundering (“AML”) program. In early 2015, we received similar requests from the U.S. Department of Justice (“DOJ”) and the Financial Crimes Enforcement Network (“FinCEN”) of the U.S. Department of Treasury. Capital One is cooperating with all agencies involved in the investigation . Intellectual Ventures Corp., et al. In June 2013, Intellectual Ventures I, LLC and Intellectual Ventures II, LLC (collectively “IV”) sued Capital One Financial Corp., Capital One Bank (USA), N.A. and Capital One, N.A. (collectively “Capital One”) for patent infringement in the U.S. District Court for the Eastern District of Virginia. In the Complaint, IV alleged infringement of patents related to various business processes across the Capital One enterprise. IV simultaneously filed patent infringement actions against numerous other financial institutions

Summary of Significant Accounting Policies (Policies)	Mar. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation and Use of Estimates The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the related disclosures. These estimates are based on information available as of the date of the consolidated financial statements. While management makes its best judgment, actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair statement of this interim financial information. Certain prior period amounts have been reclassified to conform to the current period presentation.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Capital One Financial Corporation and all other entities in which we have a controlling financial interest. We determine whether we have a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (“VIE”). All significant intercompany account balances and transactions have been eliminated.
New Accounting Standards	New Accounting Standards Adopted Consolidation: Amendments to the Consolidation Analysis In February 2015, the Financial Accounting Standards Board (“FASB”) issued revised guidance for evaluating whether organizations should consolidate certain legal entities such as limited partnerships, limited liability corporations and securitization structures. The guidance also removed the indefinite deferral of specialized guidance for certain investment funds. We adopted the guidance effective in the first quarter of 2016 on a modified retrospective basis. Our adoption of this guidance did not have an impact on our financial condition, results of operations or liquidity. See “ Note 6—Variable Interest Entities and Securitizations ”for information regarding our involvement with VIEs. Recently Issued but Not Yet Adopted Accounting Standards Improvements to Employee Share-Based Accounting In March 2016, the FASB issued revised guidance for accounting for employee share-based payments, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance is effective beginning on January 1, 2017, with early adoption permitted. We do not believe the impact of this guidance will be material to our consolidated financial statements. Leases In February 2016, the FASB issued revised guidance for leases. The guidance requires lessees to recognize right of use assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements for all leases, with certain practical expedients. This will be effective for us on January 1, 2019, with early adoption permitted. We are currently assessing the potential impact on our consolidated financial statements. Revenue from Contracts with Customers In May 2014, the FASB issued revised guidance for the recognition, measurement and disclosure of revenue from contracts with customers. The guidance is applicable to all entities and, once effective, will replace significant portions of existing industry and transaction-specific revenue recognition rules with a more principles-based recognition model. Most revenue associated with financial instruments, including interest and loan origination fees, is outside the scope of the guidance. Gains and losses on investment securities, derivatives and sales of financial instruments are similarly excluded from the scope. Subsequent to issuance of the revenue recognition guidance, the FASB has issued several updates that (i) deferred by one year the effective date for revenue recognition guidance to January 1, 2018, with early adoption permitted effective January 1, 2017; (ii) clarified its guidance for performing the principle-versus-agent analysis; and (iii) clarified guidance for identifying performance obligations allowing entities to ignore immaterial promised goods and services in the context of a contract with a customer. Entities can elect to adopt the guidance either on a full or modified retrospective basis. Full retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the earliest comparative period presented. Modified retrospective adoption will require a cumulative effect adjustment to retained earnings as of the beginning of the reporting period in which the entity first applies the new guidance. We do not plan to early adopt the guidance. We are currently assessing the potential impact of this new guidance on our consolidated financial statements and which transition method we plan to elect.
Offsetting of Financial Assets and Liabilities	Offsetting of Financial Assets and Liabilities We execute the majority of our derivative transactions and repurchase agreements under master netting arrangements. Under our existing enforceable master netting arrangements, we generally have the right to offset exposure with the same counterparty. In addition, either counterparty can generally request the net settlement of all contracts through a single payment upon default on, or termination of, any one contract. The Company offsets derivative assets and liabilities for purposes of balance sheet presentation where a right of setoff exists. As of March 31, 2016 and December 31, 2015 , derivative contracts that are executed bilaterally with a counterparty in the OTC market and then novated to and cleared through a central clearinghouse are not subject to offsetting due to the uncertainty existing around an end-user’s ability to setoff derivative contracts that have been novated to a clearinghouse.

Impaired loans without an allowance generally represent loans that have been charged down to the fair value of the underlying collateral for which we believe no additional losses have been incurred, or where the fair value of the underlying collateral meets or exceeds the loan’s amortized cost. (2) The average recorded investment of credit card loans includes finance charges and fees. (3) Although auto loans from loan recovery inventory are not reported in our loans held for investment, they are included as impaired loans above since they are reported as TD Rs.
TDR Disclosures in Progress Financial Impact of Modification	The following table presents the type, number and recorded investment amount of loans modified in TDRs that experienced a default during the period and had completed a modification event in the twelve months prior to the default. A default occurs if the loan is either 90 days or more delinquent, has been charged off as of the end of the period presented or has been reclassified from accrual to nonaccrual status.

As a result, loans entering long-term TDR payment programs in the U.K. typically continue to age and ultimately charge off even when fully in compliance with the TDR program terms.

Variable Interest Entities and Securitization [Abstract]
Carrying Amount of Assets and Liabilities of Variable Interest Entities	The table below presents a summary of VIEs, aggregated based on VIEs with similar characteristics, in which we had continuing involvement or held a variable interest as of March 31, 2016 and December 31, 2015 . We separately present information for consolidated and unconsolidated VIEs. For consolidated VIEs, we present the carrying amount of assets and liabilities reflected on our consolidated balance sheets. The assets of consolidated VIEs primarily consist of cash and loans, which we report on our consolidated balance sheets under restricted cash and loans held in consolidated trusts, respectively. The assets of a particular VIE are the primary source of funds to settle its obligations. The creditors of the VIEs typically do not have recourse to the general credit of the Company. The liabilities primarily consist of debt securities issued by the VIEs, which we report under securitized debt obligations. For unconsolidated VIEs, we present the carrying amount of assets and liabilities reflected on our consolidated balance sheets and our maximum exposure to loss. Our maximum exposure to loss is estimated based on the unlikely event that all of the assets in the VIEs become worthless and we are required to meet our maximum remaining funding obligations.

(2) The carrying amount of assets of unconsolidated securitization-related VIEs consists of retained interests associated with the securitization of option-adjustable rate mortgage (“option-ARM”) loans and letters of credit related to manufactured housing securitizations. These are reported on our consolidated balance sheets within other assets. The carrying amount of liabilities of unconsolidated securitization-related VIEs is comprised of obligations on certain swap agreements associated with the securitization of manufactured housing loans and other obligations. These are reported on our consolidated balance sheets within other liabilities.
External Debt and Receivable Balances of Securitization Programs	The table below presents the securitization-related VIEs in which we had continuing involvement as of March 31, 2016 and December 31, 2015 .

(2) The core servicing activities for the manufactured housing securitizations are completed by a third party. (3) Amortization events vary according to each specific trust agreement but generally are triggered by declines in performance or credit metrics of the underlying assets, such as net charge-off rates or delinquency rates, beyond certain predetermined thresholds. Generally, the occurrence of an amortization event changes the sequencing and amount of trust-related cash flows to the benefit of more senior interest holders.

Schedule of Assets Measured at Fair Value on Recurring Basis Quantitative Information	following table presents the significant unobservable inputs relied upon to determine the fair values of our Level 3 financial instruments on a recurring basis. We utilize multiple third-party pricing services to obtain fair value measures for our securities. Several of our third-party pricing services are only able to provide unobservable input information for a limited number of securities due to software licensing restrictions. Other third-party pricing services are able to provide unobservable input information for all securities for which they provide a valuation. As a result, the unobservable input information for the securities available for sale presented below represents a composite summary of all information we are able to obtain for a majority of our securities.
