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 digital channels, branches, Cafés and other distribution channels. As of September 30, 2021, our principal subsidiaries included: • Capital One Bank (USA), National Association (“COBNA”), which offers credit card products along with other lending products and consumer services; 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 is 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 organized for management reporting purposes into three major business segments, which are defined primarily based on the products and services provided or the types of customer served: Credit Card, Consumer Banking and Commercial Banking. We provide details on our business segments, the integration of recent acquisitions, if any, into our business segments and the allocation methodologies and accounting policies used to derive our business segment results in “Note 12—Business Segments and Revenue from Contracts with Customers.” Basis of Presentation and Use of Estimates The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”). The preparation of the consolidated 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 judgments, 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. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, and related notes thereto, included in Capital One Financial Corporation’s 2020 Annual Report on Form 10-K (“2020 Form 10-K”). Newly Adopted Accounting Standards During the Nine Months Ended September 30, 2021 Standard Guidance Adoption Timing and Financial Statement Impacts Income Tax Accounting Simplification ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes Issued December 2019 Simplifies various aspects of the guidance on accounting for income taxes. We adopted this guidance in the first quarter of 2021 using the modified retrospective and prospective methods of adoption. Our adoption of this standard did not have a material impact on our consolidated financial statements.

Credit Quality Indicators We closely monitor economic conditions and loan performance trends to assess and manage our exposure to credit risk. We discuss these risks and our credit quality indicator for each portfolio segment below. 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 based on portfolios with common risk characteristics. The risk in our credit card loan portfolio correlates to broad economic trends, such as unemployment rates and home values, as well as consumers’ financial condition, all of which can have a material effect on credit performance. The key indicator we assess in monitoring the credit quality and risk of our credit card loan portfolio is delinquency trends, including an analysis of loan migration between delinquency categories over time. The table below presents our credit card portfolio by delinquency status as of September 30, 2021 and December 31, 2020. Table 3.3: Credit Card Delinquency Status September 30, 2021 December 31, 2020 (Dollars in millions) Revolving Loans Revolving Loans Converted to Term Total Revolving Loans Revolving Loans Converted to Term Total Credit Card: Domestic credit card: Current $ 96,977 $ 369 $ 97,346 $ 95,629 $ 487 $ 96,116 30-59 days 632 14 646 734 21 755 60-89 days 417 8 425 451 13 464 Greater than 90 days 832 9 841 1,155 14 1,169 Total domestic credit card 98,858 400 99,258 97,969 535 98,504 International card businesses: Current 5,534 45 5,579 8,152 66 8,218 30-59 days 67 5 72 79 11 90 60-89 days 41 4 45 47 11 58 Greater than 90 days 72 4 76 76 10 86 Total international card businesses 5,714 58 5,772 8,354 98 8,452 Total credit card $ 104,572 $ 458 $ 105,030 $ 106,323 $ 633 $ 106,956 Consumer Banking Our consumer banking loan portfolio consists of auto 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 and home values, as well as consumers’ financial condition, all of which can have a material effect on credit performance. The key indicator we monitor when assessing the credit quality and risk of our auto loan portfolio is borrower credit scores as they measure the creditworthiness of borrowers. Delinquency trends are the key indicator we assess in monitoring the credit quality and risk of our retail banking loan portfolio. The table below presents our consumer banking portfolio of loans held for investment by credit quality indicator as of September 30, 2021 and December 31, 2020. We present our auto loan portfolio by FICO scores at origination and our retail banking loan portfolio by delinquency status, which includes all past due loans, both performing and nonperforming.

Auto credit scores generally represent average FICO scores obtained from three credit bureaus at the time of application and are not refreshed thereafter. Balances for which no credit score is available or the credit score is invalid are included in the 620 or below category. (2) Includes PPP loans of $538 million and $919 million as of September 30, 2021 and December 31, 2020, respectively . Commercial Banking The key credit quality indicator for our commercial loan portfolios is our internal risk ratings. We assign internal risk ratings to loans based on relevant information about the ability of the borrowers to repay 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 credit losses for commercial loans. Generally, loans 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 are also generally 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 our commercial banking portfolio of loans held for investment by internal risk ratings as of September 30, 2021 and December 31, 2020. The internal risk rating status includes all past due loans, both performing and nonperforming.

Troubled Debt Restructurings Additional guidance issued by the Federal Banking Agencies and contained in the Coronavirus Aid, Relief, and Economic Security Act provides banking organizations with troubled debt restructurings (“TDRs”) relief for modifications of current borrowers impacted by the COVID-19 pandemic. In adherence with the guidance, we assessed all loan modifications introduced to current borrowers in response to the COVID-19 pandemic through September 30, 2021, that would have been designated as TDRs under our existing policies, and followed guidance that any such eligible loan modifications made on a temporary and good faith basis are not considered TDRs. We consider the impact of all loan modifications, including those classified as TDRs and those offered in response to the COVID-19 pandemic, when estimating the credit quality of our loan portfolio and establishing allowance levels. For our Commercial Banking customers, enrollment in a customer assistance program is also considered in the assignment of an internal risk rating. Total recorded TDRs were $1.7 billion and $2.1 billion as of September 30, 2021 and December 31, 2020, respectively. TDRs classified as performing in our credit card and consumer banking loan portfolios totaled $1.1 billion and $1.3 billion as of September 30, 2021 and December 31, 2020, respectively. TDRs classified as performing in our commercial banking loan portfolio totaled $231 million and $442 million as of September 30, 2021 and December 31, 2020, respectively. Commitments to lend additional funds on loans modified in TDRs totaled $164 million and $173 million as of September 30, 2021 and December 31, 2020, respectively. Loans Modified in TDRs 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. The following tables present the major modification types, amortized cost amounts and financial effects of loans modified in TDRs during the three and nine months ended September 30, 2021 and 2020.

Allowance for Credit Losses and Reserve for Unfunded Lending Commitment	NOTE 4—ALLOWANCE FOR CREDIT LOSSES AND RESERVE FOR UNFUNDED LENDING COMMITMENTS Our allowance for credit losses represents management’s current estimate of expected credit losses over the contractual terms of our loans held for investment as of each balance sheet date. Expected recoveries of amounts previously charged off or expected to be charged off are recognized within the allowance. When developing an estimate of expected credit losses, we use both quantitative and qualitative methods in considering all available information relevant to assessing collectability. This may include internal information, external information or a combination of both relating to past events, current conditions, and reasonable and supportable forecasts. Management will consider and may qualitatively adjust for conditions, changes and trends in loan portfolios that may not be captured in modeled results. These adjustments are referred to as qualitative factors and represent management’s judgment of the imprecision and risks inherent in the processes and assumptions used in establishing the allowance for credit losses. Significant judgment is applied in our estimation of lifetime credit losses. We have unfunded lending commitments in our Commercial Banking business that are not unconditionally cancellable by us and for which we estimate expected credit losses in establishing a reserve. This reserve is measured using the same measurement objectives as the allowance for loans held for investment. We build or release the reserve for unfunded lending commitments through 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” in our 2020 Form 10-K for further discussion of the methodology and policy for determining our allowance for credit losses for each of our loan portfolio segments, as well as information on our reserve for unfunded lending commitments. Allowance for Credit Losses and Reserve for Unfunded Lending Commitments Activity The table below summarizes changes in the allowance for credit losses and reserve for unfunded lending commitments by portfolio segment for the three and nine months ended September 30, 2021 and 2020. Our allowance for credit losses decreased by $4.0 billion to $11.6 billion as of September 30, 2021 from December 31, 2020, primarily driven by strong credit performance and improved economic outlook.

(3) Concurrent with our adoption of the CECL standard in the first quarter of 2020, we reclassified our finance charge and fee reserve to our allowance for credit losses, with a corresponding increase to credit card loans held for investment. (4) Represents foreign currency translation adjustments and an initial allowance for purchased credit-deteriorated loans of $6 million. Credit Card Partnership Loss Sharing Arrangements We have certain credit card partnership agreements that are presented within our consolidated financial statements on a net basis, in which our partner agrees to share a portion of the credit losses on the underlying loan portfolio. The expected reimbursements from these partners are netted against our allowance for credit losses. Our methodology for estimating reimbursements is consistent with the methodology we use to estimate the allowance for credit losses on our credit card loan receivables. These expected reimbursements result in reductions to net charge-offs and the provision for credit losses. See “Note 1—Summary of Significant Accounting Policies” in our 2020 Form 10-K for further discussion of our credit card partnership agreements. The table below summarizes the changes in the estimated reimbursements from these partners for the three and nine months ended September 30, 2021 and 2020.

Variable Interest Entities and Securitization [Abstract]
Variable Interest Entities and Securitizations	NOTE 5—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 variable interest entities (“VIEs”). Our primary involvement with VIEs is related to our securitization transactions in which we transfer assets to securitization trusts. We primarily securitize credit card and auto 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 related 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 assets of our consolidated VIEs primarily consist of cash, loan receivables and the related allowance for credit losses, which we report on our consolidated balance sheets under restricted cash for securitization investors, loans held in consolidated trusts and allowance for credit losses, respectively. The assets of a particular VIE are the primary source of funds to settle its obligations. Creditors of these VIEs typically do not have recourse to our general credit. Liabilities primarily consist of debt securities issued by the VIEs, which we report under securitized debt obligations on our consolidated balance sheets. 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. The tables below present a summary of VIEs in which we had continuing involvement or held a significant variable interest, aggregated based on VIEs with similar characteristics as of September 30, 2021 and December 31, 2020. We separately present information for consolidated and unconsolidated VIEs.

(3) In certain investment structures, we consolidate a VIE which in turn holds as its primary asset an investment in an unconsolidated VIE. In these instances, we disclose the carrying amount of assets and liabilities on our consolidated balance sheets as unconsolidated VIEs to avoid duplicating our exposure, as the unconsolidated VIEs are generally the operating entities generating the exposure. The carrying amount of assets and liabilities included in the unconsolidated VIE columns above related to these investment structures were $2.2 billion of assets and $602 million of liabilities as of September 30, 2021, and $2.3 billion of assets and $596 million of liabilities as of December 31, 2020. Securitization-Related VIEs In a securitization transaction, assets are transferred to a trust, which generally meets the definition of a VIE. We engage in securitization activities as an issuer and an investor. Our primary securitization issuance activity includes credit card and auto securitizations, conducted through securitization trusts which we consolidate. Our continuing involvement in these securitization transactions mainly consists of acting as the primary servicer and holding certain retained interests. In our multifamily agency business, we originate multifamily commercial real estate loans and transfer them to Government-sponsored enterprise (“GSEs”) who may, in turn, securitize them. We retain the related mortgage servicing rights (“MSRs”) and service the transferred loans pursuant to the guidelines set forth by the GSEs. As an investor, we hold primarily RMBS, CMBS, and ABS in our investment securities portfolio, which represent variable interests in the respective securitization trusts from which those securities were issued. We do not consolidate the securitization trusts employed in these transactions as we do not have the power to direct the activities that most significantly impact the economic performance of these securitization trusts. We exclude these VIEs from the tables within this note because we do not consider our continuing involvement with these VIEs to be significant as we either invest in securities issued by the VIE and were not involved in the design of the VIE or no transfers have occurred between the VIE and us. Our maximum exposure to loss as a result of our involvement with these VIEs is the carrying value of the MSRs and investment securities on our consolidated balance sheets as well as our contractual obligations under loss sharing arrangements. See “Note 6—Goodwill and Intangible Assets” for information related to our MSRs associated with these securitizations and “Note 2—Investment Securities” for more information on the securities held in our investment securities portfolio. In addition, where we have certain lending arrangements in the normal course of business with entities that could be VIEs, we have also excluded these VIEs from the tables presented in this note. See “Note 3—Loans” for additional information regarding our lending arrangements in the normal course of business. The table below presents our continuing involvement in certain securitization-related VIEs as of September 30, 2021 and December 31, 2020. Table 5.2: Continuing Involvement in Securitization-Related VIEs (Dollars in millions) Credit Card Auto September 30, 2021: Securities held by third-party investors $ 11,367 $ 1,268 Receivables in the trusts 21,496 1,419 Cash balance of spread or reserve accounts 0 10 Retained interests Yes Yes Servicing retained Yes Yes December 31, 2020: Securities held by third-party investors $ 10,361 $ 2,053 Receivables in the trust 23,683 2,243 Cash balance of spread or reserve accounts 0 10 Retained interests Yes Yes Servicing retained Yes Yes Credit Card Securitizations We securitize a portion of our credit card loans which provides a source of funding for us. Credit card securitizations involve the transfer of credit card receivables to securitization trusts. These trusts then issue debt securities collateralized by the transferred receivables to third-party investors. We hold certain retained interests in our credit card securitizations and continue to service the receivables in these trusts. We consolidate these trusts because we are deemed to be the primary beneficiary as we have the power to direct the activities that most significantly impact the economic performance of the trusts, and the right to receive benefits or the obligation to absorb losses that could potentially be significant to the trusts. Auto Securitizations Similar to our credit card securitizations, we securitize a portion of our auto loans which provides a source of funding for us. Auto securitization involves the transfer of auto loans to securitization trusts. These trusts then issue debt securities collateralized by the transferred loans to third-party investors. We hold certain retained interests and continue to service the loans in these trusts. We consolidate these trusts because we are deemed to be the primary beneficiary as we have the power to direct the activities that most significantly impact the economic performance of the trusts, and the right to receive benefits or the obligation to absorb losses that could potentially be significant to the trusts. Other VIEs Affordable Housing Entities As part of our community reinvestment initiatives, we invest in private investment funds that make equity investments in multifamily 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 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 nine months ended September 30, 2021 and 2020, we recognized amortization of $477 million and $428 million, respectively, and tax credits of $560 million and $47 million, respectively, associated with these investments within income tax provision or benefit. The carrying value of our equity investments in these qualified affordable housing projects was $4.7 billion and $4.5 billion as of September 30, 2021 and December 31, 2020, respectively. We are periodically required to provide additional financial or other support during the period of the investments. Our liability for these unfunded commitments was $1.7 billion and $1.5 billion as of September 30, 2021 and December 31, 2020, respectively, and is largely expected to be paid from 2021 to 2024. 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 maximum exposure to these entities is limited to our variable interests in the entities which consisted of assets of approximately $4.8 billion and $4.6 billion as of September 30, 2021 and December 31, 2020, 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 approximately $11.9 billion and $11.0 billion as of September 30, 2021 and December 31, 2020, 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 consolidate 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 $2.1 billion and $2.0 billion as of September 30, 2021 and December 31, 2020, respectively, are reflected on our consolidated balance sheets in cash, loans held for investment, 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 We hold variable interests in other VIEs, including companies that promote renewable energy sources and other equity method investments. We were not required to consolidate these VIEs because we do not have the power to direct the activities that most significantly impact their economic performance. Our maximum exposure to these VIEs is limited to the investments on our consolidated balance sheets of $400 million and $436 million as of September 30, 2021 and December 31, 2020, 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	NOTE 7—DEPOSITS AND BORROWINGS Our deposits represent our largest source of funding for our assets and operations, which include checking accounts, money market deposits, negotiable order of withdrawals, savings deposits and time deposits. We also use a variety of other funding sources including short-term borrowings, senior and subordinated notes, securitized debt obligations and other borrowings. Securitized debt obligations are presented separately 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. Our total short-term borrowings generally consist of federal funds purchased and securities loaned or sold under agreements to repurchase. Our long-term debt consists of borrowings with an original contractual maturity of greater than one year. The following tables summarize the components of our deposits, short-term borrowings and long-term debt as of September 30, 2021 and December 31, 2020. The carrying value presented below for these borrowings includes unamortized debt premiums and discounts, net of debt issuance costs and fair value hedge accounting adjustments.

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities	Sep. 30, 2021
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	NOTE 8—DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Use of Derivatives and Accounting for Derivatives We regularly enter into derivative transactions to support our overall risk management activities. Our primary market risks stem from the impact on our earnings and economic value of equity due to changes in interest rates and, to a lesser extent, changes in foreign exchange rates. We manage our interest rate sensitivity by employing several techniques, which include changing the duration and re-pricing characteristics of various assets and liabilities by using interest rate derivatives. We also use foreign currency derivatives to limit our earnings and capital exposures to foreign exchange risk by hedging exposures denominated in foreign currencies. We primarily use interest rate and foreign currency swaps to hedge, but we may also 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 designate these risk management derivatives as either qualifying accounting hedges or free-standing derivatives. Qualifying accounting hedges are further designated as fair value hedges, cash flow hedges or net investment hedges. Free-standing derivatives are economic hedges that do not qualify for hedge accounting. We also offer interest rate, commodity, foreign currency derivatives and other contracts as an accommodation to our customers within our Commercial Banking business. We enter into these derivatives with our customers primarily to help them manage their interest rate risks, hedge their energy and other commodities exposures, and manage foreign currency fluctuations. We then enter into derivative contracts with counterparties to economically hedge substantially all of our subsequent exposures. See below for additional information on our use of derivatives and how we account for them: • 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 presented in the same line item in our consolidated statements of income as the earnings effect of the hedged items. Our fair value hedges primarily consist of interest rate swaps that are intended to modify our exposure to interest rate risk on various fixed-rate financial 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 accumulated other comprehensive income (“AOCI”). Those amounts are reclassified into earnings in the same period during which the forecasted transactions impact earnings and presented in the same line item in our consolidated statements of income as the earnings effect of the hedged items. Our cash flow hedges use interest rate swaps and floors that are intended to hedge the variability in interest receipts or interest payments on some of our variable-rate financial assets or liabilities. We also enter into foreign currency forward contracts to hedge our exposure to variability in cash flows related to intercompany borrowings denominated in foreign currencies. • 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 currency forward contracts to hedge the translation exposure of the net investment in our foreign operations under the forward method. • Free-Standing Derivatives: Our free-standing derivatives primarily consist of our customer accommodation derivatives and other economic hedges. The customer accommodation derivatives and the related offsetting contracts are mainly interest rate, commodity and foreign currency contracts. The other free-standing derivatives are primarily used to economically hedge the risk of changes in the fair value of our commercial mortgage loan origination and purchase commitments as well as other interests held. Changes in the fair value of free-standing derivatives are recorded in earnings as a component of other non-interest income. Derivatives Counterparty Credit Risk Counterparty Types Derivative instruments contain an element of credit risk that arises from the potential failure of a counterparty to perform according to the terms of the contract, including making payments due upon maturity of certain derivative instruments. We execute our derivative contracts primarily in over-the-counter (“OTC”) markets. We also execute interest rate and commodity futures in the exchange-traded derivative markets. Our OTC derivatives consist of both trades cleared through central counterparty clearinghouses (“CCPs”) and uncleared bilateral contracts. The Chicago Mercantile Exchange (“CME”), the Intercontinental Exchange (“ICE”) and the LCH Group (“LCH”) are our CCPs for our centrally cleared contracts. In our uncleared bilateral contracts, we enter into agreements directly with our derivative counterparties. Counterparty Credit Risk Management We manage the counterparty credit risk associated with derivative instruments by entering into legally enforceable master netting arrangements, where possible, and exchanging collateral with our counterparties, typically in the form of cash or high-quality liquid securities. The amount of collateral exchanged is dependent upon the fair value of the derivative instruments as well as the fair value of the pledged collateral and will vary over time as market variables change. When valuing collateral, an estimate of the variation in price and liquidity over time is subtracted in the form of a “haircut” to discount the value of the collateral pledged. Our exposure to derivative counterparty credit risk, at any point in time, is equal to the amount reported as a derivative asset on our balance sheet. The fair value of our derivatives is adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements and any associated cash collateral received or pledged. See Table 8.3 for our net exposure associated with derivatives. The terms under which we collateralize our exposures differ between cleared exposures and uncleared bilateral exposures. • CCPs : We clear eligible OTC derivatives with CCPs as part of our regulatory requirements. Futures commission merchants (“FCMs”) serve as the intermediary between CCPs and us. CCPs require that we post initial and variation margin through our FCMs to mitigate the risk of non-payment or default. Initial margin is required upfront by CCPs as collateral against potential losses on our cleared derivative contracts and variation margin is exchanged on a daily basis to account for mark-to-market changes in those derivative contracts. For CME, ICE and LCH-cleared OTC derivatives, we characterize variation margin cash payments as settlements. Our FCM agreements governing these derivative transactions include provisions that may require us to post additional collateral under certain circumstances. • Bilateral Counterparties : We enter into legally enforceable master netting agreements and collateral agreements, where possible, with bilateral derivative counterparties to mitigate the risk of default. We review our collateral positions on a daily basis and exchange collateral with our counterparties in accordance with these agreements. These bilateral agreements typically provide the right to offset exposure with the same counterparty and require the party in a net liability position to post collateral. Agreements with certain bilateral counterparties require both parties to maintain collateral in the event the fair values of derivative instruments exceed established exposure thresholds. Certain of these bilateral agreements 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 counterparties would have the right to terminate their derivative contract and close out existing positions. Credit Risk Valuation Adjustments We record counterparty credit valuation adjustments (“CVAs”) on our derivative assets to reflect the credit quality of our counterparties. We consider collateral and legally enforceable master netting agreements that mitigate our credit exposure to each counterparty in determining CVAs, which may be adjusted due to changes in the fair values of the derivative contracts, collateral, and creditworthiness of the counterparty. We also record debit valuation adjustments (“DVAs”) to adjust the fair values of our derivative liabilities to reflect the impact of our own credit quality. Balance Sheet Presentation The following table summarizes the notional amounts and fair values of our derivative instruments as of September 30, 2021 and December 31, 2020, 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 pledged. Derivative assets and liabilities are included in other assets and other liabilities, respectively, on our consolidated balance sheets, and their related gains or losses are included in operating activities as changes in other assets and other liabilities in the consolidated statements of cash flows.

The amortized cost basis of this portfolio was $249 million, the amount of the designated hedged items was $225 million, and the cumulative basis adjustments associated with these hedges was $1 million as of September 30, 2021. We had no such hedging relationships as of December 31, 2020. (2) Carrying value represents amortized cost. Balance Sheet Offsetting of Financial Assets and Liabilities Derivative contracts and repurchase agreements that we execute bilaterally in the OTC market are generally governed by enforceable master netting arrangements where we generally have the right to offset exposure with the same counterparty. Either counterparty can generally request to net settle all contracts through a single payment upon default on, or termination of, any one contract. We elect to offset the derivative assets and liabilities under master netting arrangements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting arrangements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting arrangements, we do not offset our derivative positions for balance sheet presentation. The following table presents the gross and net fair values of our derivative assets, derivative liabilities, resale and repurchase agreements and the related offsetting amounts permitted under U.S. GAAP as of September 30, 2021 and December 31, 2020. The table also includes cash and non-cash collateral received or pledged in accordance with such arrangements. The amount of collateral presented, however, is limited to the amount of the related net derivative fair values or outstanding balances; therefore, instances of over-collateralization are excluded.

and nine months ended September 30, 2020, respectively, related to basis adjustments on discontinued hedges. (2) Changes in fair values of cross-currency swaps attributable to changes in cross-currency basis spreads are excluded from the assessment of hedge effectiveness and recorded in other comprehensive income. The initial value of the excluded component is recognized in earnings over the life of the swap under the amortization approach. (3) See “Note 9—Stockholders’ Equity” for the effects of cash flow and net investment hedges on AOCI and amounts reclassified to net income, net of tax. (4) We recognized a gain of $83 million and $245 million for the three and nine months ended September 30, 2021, respectively, and a loss of $73 million and a gain of $20 million for the three and nine months ended September 30, 2020, respectively, on foreign exchange contracts reclassified from AOCI. These amounts were largely offset by the foreign currency transaction gains (losses) on our foreign currency denominated intercompany funding included in other non-interest income on our consolidated statements of income. In the next 12 months, we expect to reclassify into earnings net after-tax gains of $438 million recorded in AOCI as of September 30, 2021. 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 6.5 years as of September 30, 2021. 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. Free-Standing Derivatives The net impacts to our consolidated statements of income related to free-standing derivatives are presented below for the three and nine months ended September 30, 2021 and 2020.

Fair Value Measurement

Fair Value Measurement	9 Months Ended
Fair Value Measurement	Sep. 30, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurement	NOTE 11—FAIR VALUE MEASUREMENT Fair value, also referred to as an exit price, 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. 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 Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for 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. The determination and 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. For additional information on the valuation techniques used in estimating the fair value of our financial assets and liabilities on a recurring basis, see “Note 16—Fair Value Measurement” in our 2020 Form 10-K. 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 September 30, 2021 and December 31, 2020. Table 11.1: Assets and Liabilities Measured at Fair Value on a Recurring Basis September 30, 2021 Fair Value Measurements Using Netting Adjustments (1) (Dollars in millions) Level 1 Level 2 Level 3 Total Assets: Securities available for sale: U.S. Treasury securities $ 9,109 $ 0 $ 0 — $ 9,109 RMBS 0 75,428 253 — 75,681 CMBS 0 10,188 9 — 10,197 Other securities 152 3,010 0 — 3,162 Total securities available for sale 9,261 88,626 262 — 98,149 Loans held for sale 0 1,707 0 — 1,707 Other assets: Derivative assets (2) 955 3,758 191 $ (975) 3,929 Other (3) 514 16 43 — 573 Total assets $ 10,730 $ 94,107 $ 496 $ (975) $ 104,358 Liabilities: Other liabilities: Derivative liabilities (2) $ 1,904 $ 1,407 $ 152 $ (904) $ 2,559 Total liabilities $ 1,904 $ 1,407 $ 152 $ (904) $ 2,559 December 31, 2020 Fair Value Measurements Using Netting Adjustments (1) (Dollars in millions) Level 1 Level 2 Level 3 Total Assets: Securities available for sale: U.S. Treasury securities $ 9,318 $ 0 $ 0 — $ 9,318 RMBS 0 76,375 328 — 76,703 CMBS 0 11,624 111 — 11,735 Other securities 142 2,547 0 — 2,689 Total securities available for sale 9,460 90,546 439 — 100,445 Loans held for sale 0 596 0 — 596 Other assets: Derivative assets (2) 268 3,006 141 $ (1,148) 2,267 Other (3) 430 552 55 — 1,037 Total assets $ 10,158 $ 94,700 $ 635 $ (1,148) $ 104,345 Liabilities: Other liabilities: Derivative liabilities (2) $ 271 $ 1,137 $ 110 $ (739) $ 779 Total liabilities $ 271 $ 1,137 $ 110 $ (739) $ 779 __________ (1) 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 “Note 8—Derivative Instruments and Hedging Activities” for additional information. (2) Does not reflect $17 million and $31 million recognized as a net valuation allowance on derivative assets and liabilities for non-performance risk as of September 30, 2021 and December 31, 2020 , respectively. Non-performance risk is included in derivative assets and liabilities, which are part of other assets and other liabilities on the consolidated balance sheets, and is offset through non-interest income in the consolidated statements of income. (3) As of September 30, 2021 and December 31, 2020, other includes retained interests in securitizations of $43 million and $55 million, deferred compensation plan assets of $463 million and $414 million, and equity securities of $67 million and $568 million including unrealized gains of $43 million and $535 million, respectively. Level 3 Recurring Fair Val ue 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 and nine months ended September 30, 2021 and 2020. Generally, transfers into Level 3 were primarily driven by the usage of unobservable assumptions in the pricing of these financial instruments as evidenced by wider pricing variations among pricing vendors and transfers out of Level 3 were primarily driven by the usage of assumptions corroborated by market observable information as evidenced by tighter pricing among multiple pricing sources.

(4) Includes derivative assets and liabilities of $191 million and $152 million, respectively, as of September 30, 2021 and $153 million and $109 million, respectively, as of September 30, 2020. Significant Level 3 Fair Value Asset and Liability Inputs Generally, uncertainties in fair value measurements of financial instruments, such as 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 used to determine the fair values of our Level 3 financial instruments on a recurring basis. We utilize multiple vendor pricing services to obtain fair value for our securities. Several of our vendor pricing services are only able to provide unobservable input information for a limited number of securities due to software licensing restrictions. Other vendor 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. The unobservable input information for all other Level 3 financial instruments is based on the assumptions used in our internal valuation models. Table 11.3: Quantitative Information about Level 3 Fair Value Measurements Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at Significant Significant Range Weighted Average (1) Securities available for sale: RMBS $ 253 Discounted cash flows (vendor pricing) Yield 0-17% 5-20% 1-11% 30-100% 3% 11% 2% 68% CMBS 9 Discounted cash flows (vendor pricing) Yield 1% 1% Other assets: Retained interests in securitizations (2) 43 Discounted cash flows Life of receivables (months) 30-36 9-17% 2-8% 2-4% 56-151% N/A Net derivative assets (liabilities) 39 Discounted cash flows Swap rates 1-2% 1% Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at Significant Significant Range Weighted Average (1) Securities available for sale: RMBS $ 328 Discounted cash flows (vendor pricing) Yield 2-12% 8-15% 0-11% 30-100% 3% 10% 2% 73% CMBS 111 Discounted cash flows (vendor pricing) Yield 1-3% 2% Other assets: Retained interests in securitizations (2) 55 Discounted cash flows Life of receivables (months) 37-52 3-13% 2-12% 3-3% 55-70% N/A Net derivative assets (liabilities) 31 Discounted cash flows Swap rates 1% 1% __________ (1) Weighted averages are calculated by using the product of the input multiplied by the relative fair value of the instruments. (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 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 fair value accounting or when we evaluate for impairment). The following table presents the carrying value of the assets measured at fair value on a nonrecurring basis and still held as of September 30, 2021 and December 31, 2020, and for which a nonrecurring fair value measurement was recorded during the nine and twelve months then ended.

As of December 31, 2020, other assets included equity investments accounted for under the measurement alternative of $25 million, repossessed assets of $42 million and long-lived assets held for sale of $108 million. In the above table, loans held for investment are generally 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. The non-recoverable rate ranged from 0% to 100%, with a weighted average of 14%, and from 0% to 89%, with a weighted average of 14%, as of September 30, 2021 and December 31, 2020, respectively. The weighted average non-recoverable rate is calculated based on the estimated market value of the underlying collateral. The significant unobservable inputs and related quantitative information related to fair value of the other assets 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 September 30, 2021 and December 31, 2020.

Segment Reporting [Abstract]
Business Segments and Revenue from Contracts with Customers	NOTE 12—BUSINESS SEGMENTS AND REVENUE FROM CONTRACTS WITH CUSTOMERS Our principal operations are organized into three major business segments, which are defined primarily based on the products and services provided or the types of customers served: Credit Card, Consumer Banking and Commercial Banking. The operations of acquired businesses have been integrated into or managed as a part of our existing business segments. Certain activities that are not part of a segment, such as management of our corporate investment portfolio, asset/liability management by our centralized Corporate Treasury group and residual tax expense or benefit to arrive at the consolidated effective tax rate that is not assessed to our primary business segments, are included in the Other category. Basis of Presentation We report the results of each of our business segments on a continuing operations basis. 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 17—Business Segments and Revenue from Contracts with Customers” in our 2020 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 or changes in organizational alignment. The following table presents our business segment results for the three and nine months ended September 30, 2021 and 2020, selected balance sheet data as of September 30, 2021 and 2020, and a reconciliation of our total business segment results to our reported consolidated income from continuing operations, loans held for investment and deposits.

(2) Total net revenue was reduced by $123 million and $478 million in the three and nine months ended September 30, 2021, respectively, and $235 million and $942 million in the three and nine months ended September 30, 2020, respectively, for credit card finance charges and fees charged off as uncollectible. Revenue from Contracts with Customers The majority of our revenue from contracts with customers consists of interchange fees, service charges and other customer-related fees, and other contract revenue. Interchange fees are primarily from our Credit Card business and are recognized upon settlement with the interchange networks, net of rewards earned by customers. Service charges and other customer-related fees within our Consumer Banking business are primarily related to fees earned on consumer deposit accounts for account maintenance and various transaction-based services such as overdrafts and automated teller machine (“ATM”) usage. Service charges and other customer-related fees within our Commercial Banking business are mostly related to fees earned on treasury management and capital markets services. Other contract revenue in our Credit Card business consists primarily of revenue from our partnership arrangements. Other contract revenue in our Consumer Banking business consists primarily of revenue earned on certain marketing and promotional events from our auto dealers. Revenue from contracts with customers is included in non-interest income in our consolidated statements of income. The following table presents revenue from contracts with customers and a reconciliation to non-interest income by business segment for the three and nine months ended September 30, 2021 and 2020.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies, Guarantees and Others	NOTE 13—COMMITMENTS, CONTINGENCIES, GUARANTEES AND OTHERS Commitments to Lend Our unfunded lending commitments primarily consist of credit card lines, loan commitments to customers of both our Commercial Banking and Consumer Banking businesses, as well as standby and commercial letters of credit. These commitments, other than credit card lines, are legally binding conditional agreements that have fixed expirations or termination dates and specified interest rates and purposes. The contractual amount of these commitments represents the maximum possible credit risk to us should the counterparty draw upon the commitment. We generally manage the potential risk of unfunded lending commitments by limiting the total amount of arrangements, monitoring the size and maturity structure of these portfolios and applying the same credit standards for all of our credit activities. For unused credit card lines, we have not experienced and do not anticipate that all of our customers will access their entire available line at any given point in time. Commitments to extend credit other than credit card lines generally require customers to maintain certain credit standards. Collateral requirements and loan-to-value (“LTV”) ratios are the same as those for funded transactions and are established based on management’s credit assessment of the customer. These commitments may expire without being drawn upon; therefore, the total commitment amount does not necessarily represent future funding requirements. We also issue letters of credit, such as financial standby, performance standby and commercial letters of credit, 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 customer. 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 the results of these reviews are considered in assessing the adequacy of reserves for unfunded lending commitments. The following table presents the contractual amount and carrying value of our unfunded lending commitments as of September 30, 2021 and December 31, 2020. The carrying value represents our reserve and deferred revenue on legally binding commitments. Table 13.1: Unfunded Lending Commitments Contractual Amount Carrying Value (Dollars in millions) September 30, 2021 December 31, 2020 September 30, 2021 December 31, 2020 Credit card lines $ 366,744 $ 349,594 N/A N/A Other loan commitments (1) 40,545 35,836 $ 121 $ 144 Standby letters of credit and commercial letters of credit (2) 1,380 1,302 28 32 Total unfunded lending commitments $ 408,669 $ 386,732 $ 149 $ 176 __________ (1) Includes $2.1 billion and $1.8 billion of advised lines of credit as of September 30, 2021 and December 31, 2020, respectively. (2) These financial guarantees have expiration dates that range from 2021 to 2023 as of September 30, 2021. Loss Sharing Agreements Within our Commercial Banking business, we originate multifamily commercial real estate loans with the intent to sell them to the GSEs. We enter into loss sharing agreements with the GSEs upon the sale of the loans. Beginning January 1, 2020, we elected the fair value option on new loss sharing agreements. Unrealized gains and losses are recorded in other non-interest income in our consolidated statements of income. For those loss sharing agreements entered into as of and prior to December 31, 2019, we amortize the liability recorded at inception into non-interest income as we are released from risk of payment under the loss sharing agreement and record our estimate of expected credit losses each period in provision for credit losses in our consolidated statements of income. The liability recognized on our consolidated balance sheets for these loss sharing agreements was $90 million and $97 million as of September 30, 2021 and December 31, 2020, respectively. See “Note 4—Allowance for Credit Losses and Reserve for Unfunded Lending Commitments” for more information related to our credit card partnership loss sharing arrangements. 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 estimate reasonably possible losses above existing reserves, and for other disclosed matters, such an estimate is not possible at this time. For those matters below where an estimate is possible, management currently estimates the reasonably possible future losses beyond our reserves as of September 30, 2021 are approximately $200 million. Our reserve and reasonably possible loss estimates involve considerable judgment and reflect that there is still significant uncertainty regarding numerous factors that may impact the ultimate loss levels. 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 agencies, 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 In 2005, a putative class of retail merchants filed antitrust lawsuits against MasterCard and Visa and several issuing banks, including Capital One, seeking both injunctive relief and monetary damages for an alleged conspiracy by defendants to fix the level of interchange fees. Other merchants have asserted similar claims in separate lawsuits, and while these separate cases did not name any issuing banks, Visa, MasterCard and issuers, including Capital One, have entered settlement and judgment sharing agreements allocating the liabilities of any judgment or settlement arising from all interchange-related cases. The lawsuits were consolidated before the U.S. District Court for the Eastern District of New York for certain purposes and were settled in 2012. The class settlement, however, was invalidated by the United States Court of Appeals for the Second Circuit in June 2016, and the suit was bifurcated into separate class actions seeking injunctive and monetary relief, respectively. In addition, numerous merchant groups opted out of the 2012 settlement and have pursued their own claims. The claims by the injunctive relief class have not been resolved, but the settlement of $5.5 billion for the monetary damages class received final approval from the trial court, and has been appealed to the U.S. Court of Appeals for the Second Circuit. Visa and MasterCard have also settled a number of the opt-out cases, which required non-material payments from issuing banks, including Capital One. Visa created a litigation escrow account following its initial public offering of stock in 2008 that funds settlements for its member banks, and any settlements related to MasterCard-allocated losses have either already been paid or are reflected in our reserves. Cybersecurity Incident On July 29, 2019, we announced that on March 22 and 23, 2019 an outside individual gained unauthorized access to our systems. This individual obtained certain types of personal information relating to people who had applied for our credit card products and to our credit card customers (the “Cybersecurity Incident”). As a result of the Cybersecurity Incident, we are subject to numerous legal proceedings and other inquiries and could be the subject of additional proceedings and inquiries in the future. Consumer class actions . We were named as a defendant in approximately 75 putative consumer class action cases (61 in U.S. federal courts, 1 in California state court, and 13 in Canadian courts) alleging harm from the Cybersecurity Incident and seeking various remedies, including monetary and injunctive relief. The lawsuits allege breach of contract, negligence, violations of various privacy laws and a variety of other legal causes of action. The U.S. consumer class actions have been consolidated for pretrial proceedings before a multi-district litigation (“MDL”) panel in the U.S. District Court for the Eastern District of Virginia, Alexandria Division, where the remaining 29 consumer class actions are currently pending. In the third quarter of 2020, the MDL court denied in part and granted in part Capital One’s motion to dismiss and permitted pretrial discovery to continue. Securities class action . The Company and certain officers have also been named as defendants in a putative class action pending in the MDL alleging violations of certain federal securities laws in connection with statements and alleged omissions in securities filings relating to our information security standards and practices. The complaint seeks certification of a class of all persons who purchased or otherwise acquired Capital One securities from July 23, 2015 to July 29, 2019, as well as unspecified monetary damages, costs and other relief. Governmental inquiries . We have received inquiries and requests for information relating to the Cybersecurity Incident from Congress, federal regulators, relevant Canadian regulators, the Department of Justice, and the offices of approximately fourteen state Attorneys General. We are cooperating with these offices and responding to their inquiries. In August 2020, we entered into consent orders with the Federal Reserve and the Office of the Comptroller of the Currency (“OCC”) resulting from regulatory reviews of the Cybersecurity Incident and relating to ongoing enhancements of our cybersecurity and operational risk management processes. We paid an $80 million penalty to the U.S. Treasury as part of the OCC agreement. The Federal Reserve agreement did not contain a monetary penalty. Taxi Medallion Finance Investigations Beginning in 2019, we have received subpoenas from the New York Attorney General’s office and from the U.S. Attorney’s Office for the Southern District of New York, Civil and Criminal Divisions, relating to investigations of the taxi medallion finance industry we exited beginning in 2015. The subpoenas seek, among other things, information regarding our lending counterparties and practices. We are cooperating with these investigations. U.K. PPI Litigation In the U.K., we previously sold payment protection insurance (“PPI”). For several years leading up to the claims submission deadline of August 29, 2019 (as set by the U.K. Financial Conduct Authority), we received customer complaints and regulatory claims relating to PPI. As of the first quarter of 2021, COEP has materially resolved the PPI complaints and regulatory claims received prior to the deadline. Some of the claimants in the U.K. PPI regulatory claims process have subsequently initiated legal proceedings, seeking additional redress. We are responding to these proceedings as we receive them. Other Pending and Threatened Litigation In addition, we are commonly subject to various pending and threatened legal actions relating to the conduct of our normal business activities. In the opinion of management, the ultimate aggregate liability, if any, arising out of all such other pending or threatened legal actions is not expected to be material to our consolidated financial position or our results of operations.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”).
Use of Estimates	The preparation of the consolidated 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 judgments, 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.
Balance Sheet Offsetting of Financial Assets and Liabilities	Balance Sheet Offsetting of Financial Assets and Liabilities Derivative contracts and repurchase agreements that we execute bilaterally in the OTC market are generally governed by enforceable master netting arrangements where we generally have the right to offset exposure with the same counterparty. Either counterparty can generally request to net settle all contracts through a single payment upon default on, or termination of, any one contract. We elect to offset the derivative assets and liabilities under master netting arrangements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting arrangements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting arrangements, we do not offset our derivative positions for balance sheet presentation.
New Accounting Standards	Newly Adopted Accounting Standards During the Nine Months Ended September 30, 2021 Standard Guidance Adoption Timing and Financial Statement Impacts Income Tax Accounting Simplification ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes Issued December 2019 Simplifies various aspects of the guidance on accounting for income taxes. We adopted this guidance in the first quarter of 2021 using the modified retrospective and prospective methods of adoption. Our adoption of this standard did not have a material impact on our consolidated financial statements.

Schedule of Assets and Liabilities Measured at Fair Value on Recurring Basis Quantitative Information	The following table presents the significant unobservable inputs used to determine the fair values of our Level 3 financial instruments on a recurring basis. We utilize multiple vendor pricing services to obtain fair value for our securities. Several of our vendor pricing services are only able to provide unobservable input information for a limited number of securities due to software licensing restrictions. Other vendor 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. The unobservable input information for all other Level 3 financial instruments is based on the assumptions used in our internal valuation models. Table 11.3: Quantitative Information about Level 3 Fair Value Measurements Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at Significant Significant Range Weighted Average (1) Securities available for sale: RMBS $ 253 Discounted cash flows (vendor pricing) Yield 0-17% 5-20% 1-11% 30-100% 3% 11% 2% 68% CMBS 9 Discounted cash flows (vendor pricing) Yield 1% 1% Other assets: Retained interests in securitizations (2) 43 Discounted cash flows Life of receivables (months) 30-36 9-17% 2-8% 2-4% 56-151% N/A Net derivative assets (liabilities) 39 Discounted cash flows Swap rates 1-2% 1% Quantitative Information about Level 3 Fair Value Measurements (Dollars in millions) Fair Value at Significant Significant Range Weighted Average (1) Securities available for sale: RMBS $ 328 Discounted cash flows (vendor pricing) Yield 2-12% 8-15% 0-11% 30-100% 3% 10% 2% 73% CMBS 111 Discounted cash flows (vendor pricing) Yield 1-3% 2% Other assets: Retained interests in securitizations (2) 55 Discounted cash flows Life of receivables (months) 37-52 3-13% 2-12% 3-3% 55-70% N/A Net derivative assets (liabilities) 31 Discounted cash flows Swap rates 1% 1% __________ (1) Weighted averages are calculated by using the product of the input multiplied by the relative fair value of the instruments. (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.
