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 17—Business Segments and Revenue from Contracts with Customers.” 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 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. 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 (“VOE”) or a variable interest entity (“VIE”). All significant intercompany account balances and transactions have been eliminated. Voting Interest Entities VOEs are entities that have sufficient equity and provide the equity investors voting rights that give them the power to make significant decisions relating to the entity’s operations. Since a controlling financial interest in an entity is typically obtained through ownership of a majority voting interest, we consolidate our majority-owned subsidiaries and other voting interest entities in which we hold, directly or indirectly, more than 50% of the voting rights or where we exercise control through other contractual rights. Investments in which we do not hold a controlling financial interest but have significant influence over the entity’s financial and operating decisions are accounted for under the equity method. If we do not have significant influence, we measure equity investments at fair value with changes in fair value recorded through net income, except those that do not have a readily determinable fair value (for which a measurement alternative is applied). We report equity investments in other assets on our consolidated balance sheets and include our share of income or loss and dividends from those investments in other non-interest income in our consolidated statements of income. Variable Interest Entities VIEs are entities that, by design, either (i) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties; or (ii) have equity investors that do not have the ability to make significant decisions relating to the entity’s operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity. The entity that is deemed the primary beneficiary of a VIE is required to consolidate the VIE. An entity is deemed to be the primary beneficiary of a VIE if that entity has both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. In determining whether we are the primary beneficiary of a VIE, we consider both qualitative and quantitative factors regarding the nature, size and form of our involvement with the VIE, such as our role in establishing the VIE and our ongoing rights and responsibilities; our economic interests, including debt and equity investments, servicing fees and other arrangements deemed to be variable interests in the VIE; the design of the VIE, including the capitalization structure, subordination of interests, payment priority, relative share of interests held across various classes within the VIE’s capital structure and the reasons why the interests are held by us. We perform on-going reassessments to evaluate whether changes in an entity’s capital structure or changes in the nature of our involvement with the entity result in a change to the VIE designation or a change to our consolidation conclusion. See “Note 5—Variable Interest Entities and Securitizations” for further details. Balance Sheet Offsetting of Financial Assets and Liabilities Derivative contracts that we execute bilaterally in the over-the-counter (“OTC”) market or are centrally cleared are generally governed by enforceable master netting agreements 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 agreements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting agreements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting agreements, we do not offset our derivative positions for balance sheet presentation. See “Note 9—Derivative Instruments and Hedging Activities” for more details. We also elect to present securities purchased or sold under resale or repurchase agreements on a net basis when a legally enforceable master netting agreement exists and other applicable criteria are met. Security collateral received from or pledged to the counterparties are not eligible for netting and are presented gross in our consolidated balance sheet. See “Note 8—Deposits and Borrowings” and “Note 9—Derivative Instruments and Hedging Activities” for more details. Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks, interest-bearing deposits and other short-term investments, all of which, if applicable, have stated maturities of three months or less when acquired. Securities Resale and Repurchase Agreements Securities purchased under resale agreements and securities loaned or sold under agreements to repurchase, principally U.S. government and agency obligations, are not accounted for as sales but as collateralized financing transactions and recorded at the amounts at which the securities were acquired or sold, plus accrued interest. We continually monitor the market value of these securities and deliver additional collateral to or obtain additional collateral from counterparties, as appropriate. See “Note 8—Deposits and Borrowings” for further details. Significant Accounting Policies Impacted by our Adoption of the CECL Standard In the first quarter of 2020, we adopted the ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL standard”) and updated the significant accounting policies described under the “Investments Securities” and “Loans” sections below. In periods prior to 2020, the allowance for loan and lease losses represented management’s estimate of incurred loan and lease losses as fully described in “Note 1—Summary of Significant Accounting Policies” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. Investment Securities Our investment portfolio consists primarily of the following: U.S. Treasury securities; U.S. government-sponsored enterprise or agency (“Agency”) and non-agency residential mortgage-backed securities (“RMBS”); Agency commercial mortgage-backed securities (“CMBS”); and other securities. The accounting and measurement framework for our investment securities differs depending on the security classification. We classify securities as available for sale or held to maturity based on our investment strategy and management’s assessment of our intent and ability to hold the securities until maturity. We did not have any securities that were classified as held to maturity as of December 31, 2021 and 2020. We report securities available for sale on our consolidated balance sheets at fair value. The amortized cost of investment securities reflects the amount for which the security was acquired, adjusted for accrued interest, amortization of premiums, discounts, and net deferred fees and costs, any applicable fair value hedge accounting adjustments, collection of cash, and charge-offs. Unrealized gains or losses are recorded, net of tax, as a component of accumulated other comprehensive income (“AOCI”). Unamortized premiums, discounts and other basis adjustments for available for sale securities are generally recognized in interest income over the contractual lives of the securities using the effective interest method. However, premiums on certain callable investment securities are amortized to the earliest call date. We record purchases and sales of investment securities available for sale on a trade date basis. Realized gains or losses from the sale of debt securities are computed using the first-in first-out method of identification, and are included in non-interest income in our consolidated statements of income. We elect to present accrued interest for securities available for sale within interest receivable on our consolidated balance sheets. An individual debt security is impaired when the fair value of the security is less than its amortized cost. If we intend to sell an available for sale 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, any allowance for credit losses is reversed through our provision for credit losses and the difference between the amortized cost basis of the security and its fair value is recognized in our consolidated statements of income. For impaired debt securities that we have both the intent and ability to hold, the securities are evaluated to determine if a credit loss exists. The allowance for credit losses on our investment securities is recognized through our provision for credit losses and limited by the unrealized losses of a security measured as the difference between the security’s amortized cost and fair value. See further discussion below under the “Allowance for Credit Losses - Available for Sale Investment Securities” section of this Note. Our investment portfolio also includes certain debt securities that, at the time of purchase, had experienced a more-than-insignificant deterioration in credit quality since origination. Such debt securities are accounted for in accordance with accounting guidance for purchased financial assets with credit deterioration and are herein referred to as purchased credit-deteriorated (“PCD”) securities. PCD securities require the recognition of an allowance for credit losses at the time of acquisition. The allowance for credit losses is not recognized in provision for credit losses. Instead, the purchase price and the initial allowance collectively represent the amortized cost basis of a PCD security. Any non-credit discount or premium at the date of acquisition is amortized into interest income over the remaining life of the security. Subsequent to the date of purchase, we remeasure the allowance for credit losses on the amortized cost basis using the same policies as for other debt securities available for sale and changes are recognized through our provision for credit losses. See further discussion below under the “Allowance for Credit Losses - Available for Sale Investment Securities” section of this Note. We charge off any portion of an investment security that we determine is uncollectible. The amortized cost basis, excluding accrued interest, is charged off through the allowance for credit losses. Accrued interest is charged off as a reduction to interest income. Recoveries of previously charged off principal amounts are recognized in our provision for credit losses when received. Allowance for Credit Losses - Available for Sale Investment Securities We maintain an allowance for credit losses (“allowance”) that represents management’s current estimate of expected credit losses over the contractual terms of our investment securities classified as available for sale. When an investment security available for sale is impaired due to credit factors, we recognize a provision for credit losses in our consolidated statements of income and an allowance for credit losses on our consolidated balance sheets. Credit losses recognized in the allowance for credit losses are limited to the amount by which the investment security’s amortized cost basis exceeds its fair value. Investment securities in unrealized gain positions do not have an allowance for credit losses as the investment security could be sold at its fair value to prevent realization of credit losses. We exclude accrued interest from the fair value and amortized cost basis of an investment security for purposes of measuring impairment. Charge-offs of uncollectible amounts of investment securities are deducted from the allowance for credit losses. For certain of our securities available for sale, we have determined that there is no risk of impairment due to credit factors. These investment securities include high quality debt instruments that are issued and guaranteed by the United States government and its agencies, certain government-sponsored enterprises, and certain foreign sovereign governments or supranational organizations. Management performs periodic assessments to reevaluate this conclusion by considering any changes in historical losses, current conditions, and reasonable and supportable forecasts. We evaluate impairment on a quarterly basis at the individual security level and determine whether any portion of the decline in fair value is due to a credit loss. We make this determination through the use of quantitative and qualitative analyses. Our qualitative analysis includes factors such as the extent to which fair value is less than amortized cost, any changes in the security’s credit rating, past defaults or delayed payments, and adverse conditions impacting the security or issuer. A credit loss exists to the extent that management does not expect to recover the amortized cost basis. For investment securities which require further assessment, we perform a quantitative analysis using a discounted cash flow methodology and compare the present value of expected future cash flows from the security available for sale to the security’s amortized cost basis. Projected future cash flows reflect management’s best estimate and are based on our understanding of past events, current conditions, reasonable and supportable forecasts, and are discounted by the security’s effective interest rate adjusted for prepayments. The allowance for credit losses for investment securities reflects the difference by which the amortized cost basis exceeds the present value of future cash flows and is limited to the amount by which the security’s amortized cost exceeds its fair value. See “Note 2—Investment Securities” for additional information. Loans Our loan portfolio consists of loans held for investment, including loans transferred to our consolidated securitization trusts, and loans held for sale and is divided into three portfolio segments: credit card, consumer banking and commercial banking loans. Credit card loans consist of domestic and international credit card loans. Consumer banking loans consist of auto and retail banking loans. Commercial banking loans consist of commercial and multifamily real estate loans as well as commercial and industrial loans. Loan Classification We classify loans as held for investment or held for sale based on our investment strategy and management’s intent and ability with regard to the loans, which may change over time. The accounting and measurement framework for loans differs depending on the loan classification, whether we elect the fair value option, whether the loans are originated or purchased and whether purchased loans are considered to have experienced a more-than-insignificant deterioration in credit quality since origination. The presentation within the consolidated statements of cash flows is based on management’s intent at acquisition or origination. Cash flows related to loans that are acquired or originated with the intent to hold for investment are included in cash flows from investing activities on our consolidated statements of cash flows. Cash flows related to loans that are acquired or originated with the intent to sell are included in cash flows from operating activities on our consolidated statements of cash flows. Loans Held for Investment Loans that we have the ability and intent to hold for the foreseeable future and loans associated with consolidated securitization transactions are classified as held for investment. Loans classified as held for investment, except for credit card loans, are reported at their amortized cost basis, excluding accrued interest. For these loans, we elect to present accrued interest within interest receivable on our consolidated balance sheets. For credit card loans classified as held for investment, earned finance charges and fees are included in either loans held for investment (if they have been billed to the customer) or interest receivable (if they have not yet been billed to the customer). Interest income is recognized on performing loans on an accrual basis. We defer loan origination fees and direct loan origination costs on originated loans, premiums and discounts on purchased loans and loan commitment fees. We recognize these amounts in interest income as yield adjustments over the life of the loan and/or commitment period using the effective interest method. For credit card loans, loan origination fees and direct loan origination costs are amortized on a straight-line basis over a 12-month period. The amortized cost of loans held for investment is subject to our allowance for credit losses methodology described below under the “Allowance for Credit Losses - Loans Held for Investment” section of this Note. Loans Held for Sale Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Multifamily commercial real estate loans originated with the intent to sell to government-sponsored enterprises are accounted for under the fair value option. We elect the fair value option on these loans as part of our management of interest rate risk along with the corresponding forward sale commitments. Loan origination fees and direct loan origination costs are recognized as incurred and are reported in other non-interest income in the consolidated statements of income. Interest income is calculated based on the loan's stated rate of interest and is reported in interest income in the consolidated statements of income. Fair value adjustments are recorded in other non-interest income in the consolidated statements of income. All other loans classified as held for sale are recorded at the lower of cost or fair value. Loan origination fees, direct loan origination costs and any discounts and premiums are deferred until the loan is sold and are then recognized as part of the total gain or loss on sale. The fair value of loans held for sale is determined on an aggregate portfolio basis for each loan type. Fair value adjustments are recorded in other non-interest income in the consolidated statements of income. If a loan is transferred from held for investment to held for sale, then on the transfer date, any decline in fair value related to credit is recorded as a charge-off and any allowance for credit losses is reversed through our provision for credit losses. The loan is then reclassified to held for sale at its amortized cost at the date of the transfer. A valuation allowance is established, if needed, such that the loan held for sale is recorded at the lower of cost or fair value. Subsequent to transfer, we report write-downs or recoveries in fair value up to the carrying value at the date of transfer and realized gains or losses on loans held for sale in our consolidated statements of income as a component of other non-interest income. We calculate the gain or loss on loan sales as the difference between the proceeds received and the carrying value of the loans sold, net of the fair value of any residual interests retained. Loans Acquired All purchased loans, including loans transferred in a business combination, are initially recorded at fair value, which includes consideration of expected future losses, as of the date of the acquisition. To determine the fair value of loans at acquisition, we estimate discounted contractual cash flows due using an observable market rate of interest, when available, adjusted for factors that a market participant would consider in determining fair value. In determining fair value, contractual cash flows are adjusted to include prepayment estimates based upon historical payment trends, forecasted default rates and loss severities and other relevant factors. The difference between the fair value and the contractual cash flows is recorded as a loan premium or discount, which may relate to either credit or non-credit factors, at acquisition. We account for purchased loans under the accounting guidance for purchased financial assets with credit deterioration when, at the time of purchase, the loans have experienced a more-than-insignificant deterioration in credit quality since origination. We refer to these loans which are accounted for under accounting guidance for purchased financial assets with more-than-insignificant deterioration in credit quality since origination as “PCD loans”. We recognize an allowance for credit losses on purchased loans that have not experienced a more-than-insignificant deterioration in credit quality since origination at the time of purchase through earnings in a manner that is consistent with originated loans. The policies relating to the allowance for credit losses on loans is described below in the “Allowance for Credit Losses - Loans Held for Investment” section of this Note. Loan Modifications and Restructurings As part of our loss mitigation efforts, we may provide modifications to a borrower experiencing financial difficulty to improve long-term collectability of the loan and to avoid the need for foreclosure or repossession of collateral, if any. Our loan modifications typically include short-term payment deferrals, an extension of the loan term, a reduction in the interest rate, a reduction in the loan balance, or a combination of these concessions. A loan modification in which a concession is granted to a borrower experiencing financial difficulty is accounted for and reported as a troubled debt restructuring (“TDR”). See “Note 3—Loans” for additional information on our loan modifications and restructurings, including those in response to the COVID-19 pandemic. Delinquent and Nonperforming Loans The entire balance of a loan is considered contractually delinquent if the minimum required payment is not received by the first statement cycle date equal to or following the due date specified on the customer’s billing statement. Delinquency is reported on loans that are 30 or more days past due. Interest and fees continue to accrue on past due loans until the date the loan is placed on nonaccrual status, if applicable. For loan modifications, delinquency and nonaccrual status are reported in accordance with the revised terms of the loans. We generally place loans on nonaccrual status when we believe the collectability of interest and principal is not reasonably assured. Nonperforming loans generally include loans that have been placed on nonaccrual status. Loans classified as held for sale are excluded from nonperforming classification consideration. Our policies for classifying loans as nonperforming, by loan category, are as follows: • C redit card loans: As permitted by regulatory guidance issued by the Federal Financial Institutions Examination Council (“FFIEC”), our policy is generally to exempt credit card loans from being classified as nonperforming, as these loans are generally charged off in the period the account becomes 180 days past due. Consistent with industry conventions, we generally continue to accrue interest and fees on delinquent credit card loans until the loans are charged off. • Consumer banking loans: We classify consumer banking loans as nonperforming when we determine that the collectability of all interest and principal on the loan is not reasonably assured, generally when the loan becomes 90 days past due. • Commercial banking loans : We classify commercial banking loans as nonperforming as of the date we determine that the collectability of all interest and principal on the loan is not reasonably assured. • Modified loans and troubled debt restructurings: Modified loans, including TDRs, that are current at the time of the restructuring remain in accrual status if there is demonstrated performance prior to the restructuring and continued performance under the modified terms is expected. Otherwise, the modified loan is classified as nonperforming. Interest and fees accrued but not collected at the date a loan is placed on nonaccrual status are reversed against earnings. In addition, the amortization of deferred loan fees, costs, premiums and discounts is suspended. Interest and fee income are subsequently recognized only upon the receipt of cash payments. However, if there is doubt regarding the ultimate collectability of loan principal, cash received is generally applied against the principal balance of the loan. Nonaccrual loans are generally returned to accrual status when all principal and interest is current and repayment of the remaining contractual principal and interest is reasonably assured, or when the loan is both well-secured and in the process of collection and collectability is no longer doubtful. Charge-Offs We charge off loans when we determine that the loan is uncollectible. The amortized cost basis, excluding accrued interest, is charged off as a reduction to the allowance for credit losses based on the time frames presented below. Accrued interest on loans other than credit card loans determined to be uncollectible is reversed as a reduction of interest income when the loan is classified as nonperforming. For credit card loans, accrued interest is charged off simultaneously with the charge off of other components of amortized cost and as a reduction of interest income. When received, recoveries of previously charged off amounts are recorded as an increase to the allowance for credit losses (see the “Allowance for Credit Losses - Loans Held for Investment” section of this Note for information on how we account for expected recoveries). Costs to recover charged off loans are recorded as collection expense and included in our consolidated statements of income as a component of other non-interest expense as incurred. Our charge-off time frames by loan type are presented below. • Credit card loans : We generally charge off credit card loans in the period the account becomes 180 days past due. We charge off delinquent credit card loans for which revolving privileges have been revoked as part of loan workout when the account becomes 120 days past due. Credit card loans in bankruptcy are generally charged off by the end of the month following 30 days after the receipt of a complete bankruptcy notification from the bankruptcy court. Credit card loans of deceased account holders are generally charged off 5 days after receipt of notification. • Consumer banking loans: We generally charge off consumer banking loans at the earlier of the date when the account is a specified number of days past due or upon repossession of the underlying collateral. Our charge-off period for auto loans is 120 days past due. Small business banking loans generally charge off at 120 days past due based on the date the amortized cost basis is deemed uncollectible. Auto loans that have not been previously charged off where the borrower has filed for bankruptcy and the loan has not been reaffirmed charge off in the period that the loan is 60 days from the bankruptcy notification date, regardless of delinquency status. Auto loans that have not been previously charged off and have been discharged under Chapter 7 bankruptcy are charged off at the end of the month in which the bankruptcy discharge occurs. Remaining consumer loans generally are charged off within 40 days of receipt of notification from the bankruptcy court. Consumer loans of deceased account holders are charged off by the end of the month following 60 days of receipt of notification. • Commercial banking loans: We charge off commercial loans in the period we determine that the amortized cost basis is uncollectible. Allowance for Credit Losses - Loans Held for Investment We maintain an allowance for credit losses (“allowance”) that represents management’s current estimate of expected credit losses over the contractual terms of our loans held for investment. We measure the allowance on a quarterly basis through consideration of past events, including historical experience, current conditions and reasonable and supportable forecasts. We measure current expected credit losses over the contractual terms of our loans. The contractual terms are adjusted for expected prepayments but are not extended for renewals or extensions, except when an extension or renewal arises from a borrower option that is not unconditionally cancellable or through a TDR that is reasonably expected to occur. We aggregate loans sharing similar risk characteristics into pools for purposes of measuring expected credit losses. Pools are reassessed periodically to confirm that all loans within each pool continue to share similar risk characteristics. Expected credit losses for loans that do not share similar risk characteristics with other financial assets are measured individually. Expected recoveries of amounts previously charged off or expected to be charged off are recognized within the allowance, with a corresponding reduction to our provision for credit losses. At times expected recoveries may result in a negative allowance. We limit the allowance recovery expectations to amounts previously charged off and expected to be charged off. Charge-offs of uncollectible amounts result in a reduction to the allowance and recoveries of previously charged off amounts result in an increase to the allowance. When developing an estimate of expected credit losses, we use bot

Maturities and Yields of Investment Securities The table below summarizes, as of December 31, 2021, the fair value of our investment securities by major security type and contractual maturity as well as the total fair value, amortized cost and weighted-average yields of our investment securities by contractual maturity. Because borrowers may have the right to call or prepay certain obligations, the expected maturities of our securities are likely to differ from the scheduled contractual maturities presented below. The weighted-average yield below represents the effective yield for the investment securities and is calculated based on the amortized cost of each security.

Receivables [Abstract]
Loans	NOTE 3—LOANS Our loan portfolio consists of loans held for investment, including loans held in our consolidated trusts, and loans held for sale. We further divide our loans held for investment 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 and retail banking loans. Commercial banking loans consist of commercial and multifamily real estate as well as commercial and industrial loans. The information presented in this section excludes loans held for sale, which are carried at either fair value (if we elect the fair value option) or at the lower of cost or fair value. Accrued interest receivable of $1.2 billion as of both December 31, 2021 and 2020, is not included in the tables in this note. The table below presents the composition and aging analysis of our loans held for investment portfolio as of December 31, 2021 and 2020. The delinquency aging includes all past due loans, both performing and nonperforming.

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 and the U.S. Real Gross Domestic Product (“GDP”) Rate, 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 December 31, 2021 and 2020. Table 3.3: Credit Card Delinquency Status December 31, 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 $ 105,985 $ 327 $ 106,312 $ 95,629 $ 487 $ 96,116 30-59 days 760 13 773 734 21 755 60-89 days 519 9 528 451 13 464 Greater than 90 days 1,100 10 1,110 1,155 14 1,169 Total domestic credit card 108,364 359 108,723 97,969 535 98,504 International card businesses: Current 5,795 41 5,836 8,152 66 8,218 30-59 days 73 4 77 79 11 90 60-89 days 47 3 50 47 11 58 Greater than 90 days 82 4 86 76 10 86 Total international card businesses 5,997 52 6,049 8,354 98 8,452 Total credit card $ 114,361 $ 411 $ 114,772 $ 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 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 December 31, 2021 and 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 $232 million and $919 million as of December 31, 2021 and 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 December 31, 2021 and 2020. The internal risk rating status includes all past due loans, both performing and nonperforming.

(2) Includes PPP loans of $102 million and $238 million as of December 31, 2021 and 2020, respectively. Troubled Debt Restructurings Additional guidance issued by the Federal Banking Agencies and contained in the Coronavirus Aid, Relief, and Economic Security Act provided 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, 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 $1.6 billion and $2.1 billion as of December 31, 2021 and 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 December 31, 2021 and 2020, respectively. TDRs classified as performing in our commercial banking loan portfolio totaled $192 million and $442 million as of December 31, 2021 and 2020, respectively. Commitments to lend additional funds on loans modified in TDRs totaled $168 million and $173 million as of December 31, 2021 and 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 years ended December 31, 2021, 2020 and 2019.

As not every modification type is included in the table above, the total percentage of TDR activity may not add up to 100%. Some loans may receive more than one type of concession as part of the modification. (2) Due to multiple concessions granted to some troubled borrowers, percentages may total more than 100% for certain loan types. Subsequent Defaults of Completed TDR Modifications The following table presents the type, number and amortized cost 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.

We also pledged loan collateral of $26.5 billion and $25.5 billion to secure our Federal Reserve Discount Window borrowing capacity of $19.6 billion and $20.0 billion as of December 31, 2021 and 2020, respectively. In addition to loans pledged, we have securitized a portion of our credit card and auto loan portfolios. See “Note 5—Variable Interest Entities and Securitizations” for additional information. Loans Held for Sale Our total loans held for sale was $5.9 billion and $2.7 billion as of December 31, 2021 and 2020, respectively. We originated for sale $9.1 billion, $10.0 billion and $9.0 billion of commercial multifamily real estate loans in 2021, 2020 and 2019, respectively, and retained servicing rights upon the sale of these loans. Revolving Loans Converted to Term Loans For the years ended December 31, 2021 and 2020, we converted $223 million and $602 million of revolving loans to term loans, respectively, primarily in our domestic credit card and commercial banking loan portfolios.

Allowance for Credit Losses and Reserve for Unfunded Lending Commitment	NOTE 4—ALLOWANCE FOR CREDIT LOSSES AND RESERVE FOR UNFUNDED LENDING COMMITMENTS In the first quarter of 2020, we adopted the CECL standard. Accordingly, our disclosures below reflect these adoption changes. Prior period presentation was not modified to conform to the current period presentation. See “Note 1--Summary of Significant Accounting Policies” for additional information. 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. Significant judgment is applied in our estimation of lifetime credit losses. 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. For credit card loans, accrued interest is charged off simultaneously with the charge off of other components of amortized cost as a reduction of revenue. Total net revenue was reduced by $629 million and $1.1 billion in 2021 and 2020, respectively for finance charges and fees charged-off as uncollectible and by $1.4 billion in 2019 for the estimated uncollectible amount of billed finance charges and fees and related 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” 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 years ended December 31, 2021, 2020 and 2019. Our allowance for credit losses decreased by $4.1 billion to $11.4 billion as of December 31, 2021 from 2020, primarily driven by strong credit performance and an improved economic outlook.

(5) 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” for further discussion of our credit card partnership agreements. The table below summarizes the changes in the estimated reimbursements from these partners for the years ended December 31, 2021, 2020 and 2019.

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 the maximum amount of any 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 December 31, 2021 and 2020. We separately present information for consolidated and unconsolidated VIEs. Table 5.1: Carrying Amount of Consolidated and Unconsolidated VIEs December 31, 2021 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: (1) Credit card loan securitizations (2) $ 21,569 $ 13,016 $ 0 $ 0 $ 0 Auto loan securitizations 2,552 2,187 0 0 0 Total securitization-related VIEs 24,121 15,203 0 0 0 Other VIEs: (3) Affordable housing entities 263 27 4,774 1,454 4,774 Entities that provide capital to low-income and rural communities 2,074 26 0 0 0 Other 0 0 383 0 383 Total other VIEs 2,337 53 5,157 1,454 5,157 Total VIEs $ 26,458 $ 15,256 $ 5,157 $ 1,454 $ 5,157 December 31, 2020 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: (1) Credit card loan securitizations (2) $ 22,066 $ 10,338 $ 0 $ 0 $ 0 Auto loan securitizations 2,360 2,055 0 0 0 Total securitization-related VIEs 24,426 12,393 0 0 0 Other VIEs: (3) Affordable housing entities 242 17 4,602 1,240 4,602 Entities that provide capital to low-income and rural communities 1,951 26 0 0 0 Other 0 0 436 0 436 Total other VIEs 2,193 43 5,038 1,240 5,038 Total VIEs $ 26,619 $ 12,436 $ 5,038 $ 1,240 $ 5,038 __________ (1) Excludes insignificant VIEs from previously exited businesses. (2) Represents the carrying amount of assets and liabilities owned by the VIE, which includes the seller’s interest and repurchased notes held by other related parties. (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 $568 million of liabilities as of December 31, 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 enterprises (“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 Other 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 December 31, 2021 and 2020. Table 5.2: Continuing Involvement in Securitization-Related VIEs (Dollars in millions) Credit Card Auto December 31, 2021: Securities held by third-party investors $ 12,808 $ 2,186 Receivables in the trusts 22,454 2,418 Cash balance of spread or reserve accounts 0 13 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 years ended December 31, 2021 and 2020, we recognized amortization of $633 million and $556 million, respectively, and tax credits of $644 million and $607 million, respectively, associated with these investments within income tax provision. The carrying value of our equity investments in these qualified affordable housing projects was $4.7 billion and $4.5 billion as of December 31, 2021 and 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 December 31, 2021 and 2020, respectively, and is largely expected to be paid from 2022 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 December 31, 2021 and 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 December 31, 2021 and 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 December 31, 2021 and 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 $383 million and $436 million as of December 31, 2021 and 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.

We recorded $79 million and $69 million of amortization expense for the years ended December 31, 2021 and 2020, respectively. Goodwill The following table presents changes in carrying amount of goodwill by each of our business segments as of December 31, 2021 , 2020 and 2019. There were no changes in the carrying amount of goodwill by each of our business segments for the year ended December 31, 2020. We did not recognize any goodwill impairment during 2021, 2020 or 2019.

An impairment of a reporting unit’s goodwill is determined based on the amount by which the reporting unit’s carrying value exceeds its fair value, limited to the amount of goodwill allocated to the reporting unit. The fair value of reporting units is calculated using a discounted cash flow methodology, a form of the income approach. The calculation uses projected cash flows based on each reporting unit’s internal forecast and uses the perpetuity growth method to calculate terminal values. These cash flows and terminal values are then discounted using appropriate discount rates, which are largely based on our external cost of equity with adjustments for risk inherent in each reporting unit. Capital is allocated based on each reporting unit’s specific regulatory capital requirements, economic capital requirements, and underlying risks. Consolidated stockholder’s equity in excess of the sum of all reporting unit’s capital requirements that is not identified for future capital needs, such as dividends, share buybacks, or other strategic initiatives, is allocated to the reporting units and the Other category and assumed distributed to equity holders in future periods. Our discounted cash flow analysis requires management to make judgments about future loan and deposit growth, revenue growth, credit losses, and capital rates. The reasonableness of our fair value calculation is assessed by reference to a market-based approach using comparable market multiples and recent market transactions where available. Intangible Assets In connection with our acquisitions, we recorded intangible assets that include PCCR intangibles, sponsorship, customer and merchant relationships, partnership, trade names, and other customer contract intangibles. At acquisition, the PCCR intangibles reflect the estimated value of existing credit card holder relationships. There were no impairments of intangible assets in 2021. Intangible assets are typically amortized over their respective estimated useful lives on either an accelerated or straight-line basis. The following table summarizes the actual amortization expense recorded for the years ended December 31, 2021, 2020 and 2019 and the estimated future amortization expense for intangible assets as of December 31, 2021: Table 6.3: Amortization Expense (Dollars in millions) Amortization Actual for the year ended December 31, 2019 $ 112 2020 60 2021 29 Estimated future amounts for the year ending December 31, 2022 51 2023 20 2024 14 2025 9 2026 4 Thereafter 5 Total estimated future amounts $ 103

Leases Our primary involvement with leases is in the capacity as a lessee where we lease premises to support our business. A majority of our leases are operating leases of office space, retail bank branches and Cafés. For real estate leases, we have elected to account for the lease and non-lease components together as a single lease component. Our operating leases expire at various dates through 2071, and many of them require variable lease payments by us, of property taxes, insurance premiums, common area maintenance and other costs. Certain of these leases also have extension or termination options, and we assess the likelihood of exercising such options. If it is reasonably certain that we will exercise the options, then we include the impact in the measurement of our right-of-use assets and lease liabilities. Our right-of-use assets and lease liabilities for operating leases are included in other assets other liabilities The following tables present information about our operating lease portfolio and the related lease costs as of and for the years ended December 31, 2021 and 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	NOTE 9—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 stems 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 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 agreements, where applicable, and exchanging collateral with our counterparties, typically in the form of cash or high-quality liquid securities. We exchange collateral in two primary forms: variation margin, which mitigates the risk of changes in value due to daily market movements and is exchanged daily, and initial margin, which mitigates the risk of potential future exposure of a derivative and is exchanged at the outset of a transaction and adjusted daily. We exchange both variation margin and initial margin for cleared and uncleared bilateral contracts. The amount of collateral exchanged for variation margin 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. The amount of the initial margin exchanged is dependent upon 1) the calculation of initial margin exposure, as prescribed by 1a) the U.S. prudential regulators’ margin rules for uncleared derivatives (“PR Rules”) or 1b) the CCPs for cleared derivatives and 2) the fair value of the pledged collateral; it 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 collateral received or pledged. See Table 9.3 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. We also clear exchange-traded instruments, like futures, with CCPs. 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 by CCPs as collateral against potential losses on our exchange-traded and 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, variation margin cash payments are required to be characterized 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 master netting agreements and collateral agreements with bilateral derivative counterparties, where applicable, to mitigate the risk of default. 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 uncleared derivatives 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 December 31, 2021 and 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 $247 million, the amount of the designated hedged items was $225 million, and the cumulative basis adjustments associated with these hedges was $3 million as of December 31, 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 agreements 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 agreements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting agreements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting agreements, 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 December 31, 2021 and 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.

(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 10—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 $163 million for the years ended December 31, 2021 and loss of $57 million, $341 million for the years ended December 31, 2020 and 2019 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 $286 million recorded in AOCI as of December 31, 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 6.2 years as of December 31, 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.

Regulatory and Capital Adequacy

Regulatory and Capital Adequacy	12 Months Ended

Mortgage Banking [Abstract]
Regulatory and Capital Adequacy	NOTE 11—REGULATORY AND CAPITAL ADEQUACY Regulation and Capital Adequacy The Company and the Banks are subject to the regulatory capital requirements established by the Federal Reserve and the Office of the Comptroller of the Currency (“OCC”) respectively (the “Basel III Capital Rules”). The Basel III Capital Rules implement certain capital requirements published by the Basel Committee on Banking Supervision (“Basel Committee”), along with certain provisions of the Dodd-Frank Act and other capital provisions. Moreover, the Banks, as insured depository institutions, are subject to prompt corrective action (“PCA”) capital regulations, which require the Federal Reserve, OCC and the Federal Deposit Insurance Corporation (collectively, the “Federal Banking Agencies”) to take prompt corrective action for banks that do not meet PCA capital requirements. Under the Basel III Capital Rules, we must maintain a minimum common equity Tier 1 (“CET1”) capital ratio of 4.5% , a Tier 1 capital ratio of 6.0%, and a total capital ratio of 8.0%, in each case in relation to risk-weighted assets. In addition, we must maintain a minimum leverage ratio of 4.0% and a minimum supplementary leverage ratio of 3.0% . We are also subject to the capital conservation buffer and countercyclical capital buffer requirements, as described below. Following amendments to the Basel III Capital Rules in October 2019 by the Federal Banking Agencies to provide for tailored application of certain capital requirements across different categories of banking institutions (the “Tailoring Rules”), the Company, as a bank holding company (“BHC”) with total consolidated assets of at least $250 billion but less than $700 billion and not exceeding any of the applicable risk-based thresholds, is a Category III institution. As a Category III institution, effective January 1, 2020, we are no longer subject to the Basel III Advanced Approaches framework and certain associated capital requirements, and we have elected to exclude certain elements of AOCI from our regulatory capital as permitted for a Category III institution. We remain subject to the countercyclical capital buffer requirement (which is currently set at 0%) and supplementary leverage ratio requirement of 3.0%. Global systemically important banks (“G-SIBs”) that are based in the U.S. are subject to an additional CET1 capital requirement known as the “G-SIB Surcharge.” We are not a G-SIB based on the most recent available data and thus we are not subject to a G-SIB Surcharge. The Federal Banking Agencies adopted a final rule (the “CECL Transition Rule”) that provides banking institutions an optional five-year transition period to phase in the impact of the current expected credit loss (“CECL”) standard on their regulatory capital (the “CECL Transition Election”). We adopted the CECL standard (for accounting purposes) as of January 1, 2020, and made the CECL Transition Election (for regulatory capital purposes) in the first quarter of 2020. Therefore, the applicable amounts presented in this Report reflect such election. Pursuant to the CECL Transition Rule, a banking institution could elect to delay the estimated impact of adopting CECL on its regulatory capital through December 31, 2021 and then phase in the estimated cumulative impact from January 1, 2022 through December 31, 2024. For the “day 2” ongoing impact of CECL during the initial two years, the Federal Banking Agencies used a uniform “scaling factor” of 25% as an approximation of the increase in the allowance under the CECL standard compared to the prior incurred loss methodology. Accordingly, from January 1, 2020 through December 31, 2021, electing banking institutions were permitted to add back to their regulatory capital an amount equal to the sum of the after-tax “day 1” CECL adoption impact and 25% of the increase in the allowance since the adoption of the CECL standard. From January 1, 2022 through December 31, 2024, the after-tax “day 1” CECL adoption impact and the cumulative “day 2” ongoing impact are being phased in to regulatory capital at 25% per year. The following table summarizes the capital impact delay and phase in period on our regulatory capital from years 2020 to 2025. Capital Impact Delayed Phase In Period 2020 2021 2022 2023 2024 2025 “Day 1” CECL adoption impact Capital impact delayed to 2022 25% Phased In 50% Phased In 75% Phased In Fully Phased In Cumulative “day 2” ongoing impact 25% scaling factor as an approximation of the increase in allowance under CECL As of December 31, 2021, we added back an aggregate amount of $2.4 billion, after taxes, to our regulatory capital pursuant to the CECL Transition Rule. The Company’s CET1 capital ratio, reflecting the CECL Transition Rule, was 13.1% as of December 31, 2021, and would have been 12.4% excluding the impact of the CECL Transition Rule (or "on a fully phased-in basis"). For additional information about the capital adequacy guidelines to which we are subject, see “Part I—Item 1. Business—Supervision and Regulation.” The following table provides a comparison of our regulatory capital amounts and ratios under the Basel III Standardized Approach subject to the applicable transition provisions, the regulatory minimum capital adequacy ratios and the applicable well-capitalized standard for each ratio as of December 31, 2021 and 2020.

We exceeded the minimum capital requirements and each of the Banks exceeded the minimum regulatory requirements and were well-capitalized under PCA requirements as of both December 31, 2021 and 2020. Regulatory restrictions exist that limit the ability of the Banks to transfer funds to our BHC. As of December 31, 2021, funds available for dividend payments from COBNA and CONA were $531 million and $447 million, respectively. Applicable

Stock-Based Compensation Plans

Stock-Based Compensation Plans	12 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation Plans	NOTE 13—STOCK-BASED COMPENSATION PLANS Stock Plans We have one active stock-based compensation plan available for the issuance of shares to employees, directors and third-party service providers (if applicable). As of December 31, 2021, under the Amended and Restated 2004 Stock Incentive plan (“2004 Plan”), we are authorized to issue 67 million common shares in various forms, primarily share-settled RSUs, performance share units (“PSUs”), and non-qualified stock options. Of this amount, approximately 17 million shares remain available for future issuance as of December 31, 2021. The 2004 Plan permits the use of newly issued shares or treasury shares upon the settlement of options and stock-based incentive awards, and we generally settle by issuing new shares. We also issue cash-settled restricted stock units. These cash-settled units are not counted against the common shares authorized for issuance or available for issuance under the 2004 Plan. Cash-settled units vesting during 2021, 2020 and 2019 resulted in cash payments to associates of $7 million, $12 million and $15 million, respectively. There was no unrecognized compensation cost for unvested cash-settled units as of December 31, 2021. Total stock-based compensation expense recognized during 2021, 2020 and 2019 was $331 million, $203 million and $239 million, respectively. The total income tax benefit for stock-based compensation recognized during 2021, 2020 and 2019 was $62 million, $43 million and $50 million, respectively. In addition, we maintain an Associate Stock Purchase Plan (“Purchase Plan”), which is a compensatory plan under the accounting guidance for stock-based compensation. Related to the Purchase Plan, we recognized compensation expense of $33 million, $30 million and $25 million for 2021, 2020 and 2019, respectively. We also maintain a Dividend Reinvestment and Stock Purchase Plan, which allows participating stockholders to purchase additional shares of our common stock through automatic reinvestment of dividends or optional cash investments. Restricted Stock Units and Performance Share Units RSUs represent share-settled awards that do not contain performance conditions and are granted to certain employees at no cost to the recipient. RSUs generally vest over three years from the date of grant; however, some RSUs cliff vest on or shortly after the first or third anniversary of the grant date. RSUs are subject to forfeiture until certain restrictions have lapsed, including continued employment for a specified period of time. PSUs represent share-settled awards that contain performance conditions and are granted to certain employees at no cost to the recipient. PSUs generally vest over three years from the date of grant; however, some PSUs cliff vest on or shortly after the third anniversary of the grant date. The number of PSUs that step vest over three years can be reduced by 50% or 100% depending on whether specific performance goals are met during the vesting period. The number of three-year cliff vesting PSUs that will ultimately vest is contingent upon meeting specific performance goals over a three-year period. These PSUs also include an opportunity to receive from 0% to 150% of the target number of common shares. A recipient of an RSU or PSU is entitled to receive a share of common stock after the applicable restrictions lapse and is generally entitled to receive cash payments or additional shares of common stock equivalent to any dividends paid on the underlying common stock during the period the RSU or PSU is outstanding, but is not entitled to voting rights. Generally, the value of RSUs and PSUs will equal the fair value of our common stock on the date of grant and the expense is recognized over the vesting period. Certain PSUs have discretionary vesting conditions and are remeasured at fair value each reporting period. The following table presents a summary of 2021 activity for RSUs and PSUs. Table 13.1: Summary of Restricted Stock Units and Performance Share Units Restricted Stock Units Performance Share Units (1) (Shares/units in thousands) Units Weighted-Average Units Weighted-Average Unvested as of January 1, 2021 3,833 $ 86.14 1,761 $ 96.15 Granted (2) 2,123 127.37 873 112.51 Vested (1,600) 90.69 (760) 98.74 Forfeited (246) 105.83 (109) 101.02 Unvested as of December 31, 2021 4,110 $ 104.50 1,765 $ 102.84 _________ (1) Granted and vested include adjustments for achievement of specific performance goals for performance share units granted in prior periods. (2) The weighted-average grant date fair value of RSUs was $92.04 and $83.29 in 2020 and 2019, respectively. The weighted-average grant date fair value of PSUs was $100.04 and $78.18 in 2020 and 2019, respectively. The total fair value of RSUs that vested during 2021, 2020 and 2019 was $202 million, $140 million and $122 million, respectively. The total fair value of PSUs that vested was $94 million in 2021 and $82 million in both 2020 and 2019. As of December 31, 2021, the unrecognized compensation expense related to unvested RSUs is $247 million, which is expected to be amortized over a weighted-average period of approximately 1.9 years; and the unrecognized compensation related to unvested PSUs was $38 million, which is expected to be amortized over a weighted-average period of approximately one year. Stock Options Stock options have a maximum contractual term of 10 years. Generally, the exercise price of stock options will equal the fair market value of our common stock on the date of grant. Option vesting is determined at the time of grant and may be subject to the achievement of any applicable performance conditions. Options generally become exercisable over three years beginning on the first anniversary of the date of grant; however, some option grants cliff vest on or shortly after the first or third anniversary of the grant date. The following table presents a summary of 2021 activity for stock options and the balance of stock options exercisable as of December 31, 2021.

Retirement Benefits [Abstract]
Employee Benefit Plans	NOTE 14—EMPLOYEE BENEFIT PLANS Defined Contribution Plan We sponsor a contributory Associate Savings Plan (the “Plan”) in which all full-time and part-time associates over the age of 18 are eligible to participate. We make non-elective contributions to each eligible associate’s account and match a portion of associate contributions. We also sponsor a voluntary non-qualified deferred compensation plan in which select groups of employees are eligible to participate. We make contributions to this plan based on participants’ deferral of salary, bonuses and other eligible pay. In addition, we match participants’ excess compensation (compensation over the Internal Revenue Service (“IRS”) compensation limit) less deferrals. We contributed a total of $378 million, $350 million and $316 million to these plans during the years ended December 31, 2021, 2020 and 2019, respectively. Defined Benefit Pension and Other Postretirement Benefit Plans We sponsor several frozen plans, including a qualified defined benefit pension plan, several non-qualified defined benefit pension plans, and a plan that provides other postretirement benefits, including medical and life insurance coverage. Our pension plans and the other postretirement benefit plan are valued using December 31 as the measurement date each year. Our policy is to amortize prior service amounts on a straight-line basis over the average remaining years of service to full eligibility for benefits of active plan participants.

We recognized a pre-tax gain of $4 million, $4 million and $18 million in other comprehensive income for our defined benefit pension plans and other postretirement benefit plan in 2021, 2020 and 2019, respectively. Pre-tax amounts recognized in AOCI that have not yet been recognized as a component of net periodic benefit cost consist of net actuarial loss of $33 million and $40 million for our defined benefit pension plans as of December 31, 2021 and 2020, respectively, and net actuarial gain of $3 million and $6 million for our other postretirement benefit plan as of December 31, 2021 and 2020, respectively. There was no meaningful prior service cost recognized in AOCI. Plan Assets and Fair Value Measurement Plan assets are invested using a total return investment approach whereby a mix of equity securities and debt securities are used to preserve asset values, diversify risk and enhance our ability to achieve our benchmark for long-term investment return. Investment strategies and asset allocations are based on careful consideration of plan liabilities, the plan’s funded status and our financial condition. Investment performance and asset allocation are measured and monitored on a daily basis. As of December 31, 2021 and 2020, our plan assets totaled $279 million and $280 million, respectively. We invested substantially all our plan assets in common collective trusts, which primarily consist of domestic and international equity securities, government securities and corporate and municipal bonds. Our plan assets were classified as Level 2 in the fair value hierarchy as of December 31, 2021 and 2020. For information on fair value measurements, including descriptions of Level 1, 2 and 3 of the fair value hierarchy and the valuation methods we utilize, see “Note 16—Fair Value Measurement.” Expected Future Benefit Payments As of December 31, 2021, the benefits expected to be paid in the next ten years totaled $108 million for our defined pension benefit plans and $12 million for our other postretirement benefit plan, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 15—INCOME TAXES We recognize the current and deferred tax consequences of all transactions that have been recognized in the financial statements using the provisions of the enacted tax laws. Current income tax expense represents our estimated taxes to be paid or refunded for the current period and includes income tax expense related to our uncertain tax positions, as well as tax-related interest and penalties. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We record valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. We record the effect of remeasuring deferred tax assets and liabilities due to a change in tax rates or laws as a component of income tax expense related to continuing operations for the period in which the change is enacted. We subsequently release income tax effects stranded in AOCI using a portfolio approach. Income tax benefits are recognized when, based on their technical merits, they are more likely than not to be sustained upon examination. The amount recognized is the largest amount of benefit that is more likely than not to be realized upon settlement. The following table presents significant components of the provision for income taxes attributable to continuing operations for the years ended December 31, 2021, 2020 and 2019. Table 15.1: Significant Components of the Provision for Income Taxes Attributable to Continuing Operations Year Ended December 31, (Dollars in millions) 2021 2020 2019 Current income tax provision: Federal taxes $ 2,173 $ 1,676 $ 1,207 State taxes 485 370 301 International taxes 152 67 129 Total current provision $ 2,810 $ 2,113 $ 1,637 Deferred income tax provision (benefit): Federal taxes $ 490 $ (1,357) $ (222) State taxes 91 (266) (45) International taxes 24 (4) (29) Total deferred provision (benefit) 605 (1,627) (296) Total income tax provision $ 3,415 $ 486 $ 1,341 The international income tax provision is related to pre-tax earnings from foreign operations of approximately $677 million, $293 million and $215 million in 2021, 2020 and 2019, respectively. Total income tax provision does not reflect the tax effects of items that are included in AOCI, which include a tax benefit of $985 million in 2021 and tax provisions of $702 million and $727 million in 2020 and 2019, respectively. See “Note 10—Stockholders’ Equity” for additional information. The following table presents the reconciliation of the U.S. federal statutory income tax rate to the effective income tax rate applicable to income from continuing operations for the years ended December 31, 2021, 2020 and 2019.

Our gross federal net operating loss carryforwards were $25 million and $36 million as of December 31, 2021 and 2020, respectively. These operating loss carryforwards were attributable to acquisitions and will expire from 2029 to 2037, though $20 million has no expiration. Under IRS rules, our ability to utilize these losses against future income is limited. The net tax values of our state net operating loss carryforwards were $258 million and $250 million as of December 31, 2021 and 2020, respectively, and they will expire from 2022 to 2040. Our foreign tax credit carryforwards were $91 million and $56 million as of December 31, 2021and 2020, respectively, and they will expire from 2028 to 2031. Our valuation allowance increased by $59 million to $355 million as of December 31, 2021 compared to $296 million as of December 31, 2020. Of the total increase, $35 million is related to the current year increase in our foreign tax credit carryforwards that will not be realized prior to expiration. The remaining increase of $24 million is related to reducing state net operating losses and interest carryforwards to the amount we have determined is more likely than not to be realized. We recognize accrued interest and penalties related to income taxes as a component of income tax expense. We recognized a $30 million tax benefit in 2021 and $16 million and $4 million of such expense in 2020 and 2019, respectively. The following table presents the accrued balance of tax, interest and penalties related to unrecognized tax benefits. Table 15.4: Reconciliation of the Change in Unrecognized Tax Benefits (Dollars in millions) Gross Accrued Gross Tax, Balance as of January 1, 2019 $ 440 $ 35 $ 475 Additions for tax positions related to the current year 23 17 40 Additions for tax positions related to prior years 12 4 16 Reductions for tax positions related to prior years due to IRS and other settlements (44) (25) (69) Balance as of December 31, 2019 431 31 462 Additions for tax positions related to the current year 33 — 33 Additions for tax positions related to prior years 3 21 24 Reductions for tax positions related to prior years due to IRS and other settlements (16) (6) (22) Balance as of December 31, 2020 451 46 497 Additions for tax positions related to prior years 1 4 5 Reductions for tax positions related to prior years due to IRS and other settlements (47) (36) (83) Balance as of December 31, 2021 $ 405 $ 14 $ 419 Portion of balance at December 31, 2021 that, if recognized, would impact the effective income tax rate $ 143 $ 10 $ 153 We are subject to examination by the IRS and other tax authorities in certain countries and states in which we operate. The tax years subject to examination vary by jurisdiction. During 2021, we continued to participate in the IRS Compliance Assurance Process (“CAP”) for our open federal income tax return years and have been accepted into CAP for 2022. During 2021, the IRS review of our 2017, 2018, 2019, and 2020 federal income tax returns was substantially completed, with no open issues remaining. The examination of these returns is expected to be closed in 2022. We expect that the IRS review of our 2021 federal income tax return will be substantially completed prior to its filing in 2022. It is reasonably possible that further adjustments to the Company’s unrecognized tax benefits may be made within 12 months of the reporting date as a result of future judicial or regulatory interpretations of existing tax laws. At this time, an estimate of the potential changes to the amount of unrecognized tax benefits cannot be made. As of December 31, 2021, the Company had approximately $1.8 billion of unremitted earnings of subsidiaries operating outside the U.S. that upon repatriation would have no additional U.S. income taxes. In accordance with the guidance for accounting for income taxes in special areas, nearly all these earnings are considered by management to be invested indefinitely.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	NOTE 16—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. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following describes the valuation techniques used in estimating the fair value of our financial assets and liabilities recorded at fair value on a recurring basis. Investment Securities We measure the fair value of our U.S. Treasury securities using quoted prices in active markets. For the majority of securities in other investment categories, we utilize multiple vendor pricing services to obtain fair value measurements. We use a waterfall of pricing vendors determined using our annual assessment of pricing service performance. A pricing service may be considered as the preferred or primary pricing provider depending on how closely aligned its prices are to other vendor prices, and how consistent the prices are with other available market information. The price of each security is confirmed by comparing such price to other vendor prices before it is finalized. RMBS and CMBS are generally classified as Level 2 or 3. When significant assumptions are not consistently observable, fair values are derived using the best available data. Such data may include quotes provided by dealers, valuation from external pricing services, independent pricing models, or other model-based valuation techniques, for example, calculation of the present values of future cash flows incorporating assumptions such as benchmark yields, spreads, prepayment speeds, credit ratings and losses. Generally, the external pricing services utilize observable market data to the extent available. Pricing models may be used, which can vary by asset class, and may also incorporate available trade, bid and other market information. Across asset classes, information such as trader/dealer inputs, credit spreads, forward curves and prepayment speeds are used to help determine appropriate valuations. Because many fixed income securities do not trade on a daily basis, the pricing models may apply available information through processes such as benchmarking curves, grouping securities based on their characteristics and using matrix pricing to prepare valuations. In addition, model processes are used by the pricing services to develop prepayment assumptions. We validate the pricing obtained from the primary pricing providers through comparison of pricing to additional sources, including other pricing services, dealer pricing indications in transaction results and other internal sources. Pricing variances among different pricing sources are analyzed. Additionally, on an on-going basis, we request more detailed information from the valuation vendors to understand the pricing methodology and assumptions used to value the securities. Derivative Assets and Liabilities We use both exchange-traded and OTC derivatives to manage our interest rate, foreign currency and commodity risk exposures. When quoted market prices are available and used to value our exchange-traded derivatives, we classify them as Level 1. However, the majority of our derivatives do not have readily available quoted market prices. Therefore, we value most of our derivatives using vendor-based models. We primarily rely on market observable inputs for these models, including, for example, interest rate yield curves, credit curves, option volatility and currency rates. These inputs can vary depending on the type of derivatives and nature of the underlying rate, price or index upon which the value of the derivative is based. We typically classify derivatives as Level 2 when significant inputs can be observed in a liquid market and the model itself does not require significant judgment. When instruments are traded in less liquid markets and significant inputs are unobservable, such as interest rate swaps whose remaining terms do not correlate with market observable interest rate yield curves, such derivatives are classified as Level 3. We consider the impact of credit risk valuation adjustments when measuring the fair value of derivative contracts in order to reflect the credit quality of the counterparty and our own credit quality. Official internal pricing is compared against additional pricing sources such as external valuation agents and other internal sources. Pricing variances among different pricing sources are analyzed and validated. These derivatives are included in other assets or other liabilities on the consolidated balance sheets. Loans Held for Sale In our commercial business, we originate multifamily commercial real estate loans with the intent to sell them to GSEs. Beginning in the fourth quarter of 2019, we elected the fair value option for such loans as part of our management of interest rate risk in our multifamily agency business. These held for sale loans are valued based on market observable inputs and are therefore classified as Level 2. Unrealized gains and losses on these loans are recorded in other non-interest income in our consolidated statements of income. Retained Interests in Securitizations We have retained interests in various mortgage securitizations from previous acquisitions. Our retained interests primarily include interest-only bonds and negative amortization bonds. We record these retained interests at fair value using market indications and valuation models to calculate the present value of future cash flows. The models incorporate various assumptions that market participants use in estimating future cash flows including voluntary prepayment rate, discount rate, default rate and loss severity. Due to the use of significant unobservable inputs, retained interests in securitizations are classified as Level 3 under the fair value hierarchy. Deferred Compensation Plan Assets We offer a voluntary non-qualified deferred compensation plan to eligible associates. In addition to participant deferrals, we make contributions to the plan. Participants invest these contributions in a variety of publicly traded mutual funds. The plan assets, which consist of publicly traded mutual funds, are classified as Level 1. The determination of the leveling 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 observable or 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. The following table displays our assets and liabilities measured on our consolidated balance sheets at fair value on a recurring basis as of December 31, 2021 and 2020.

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 years ended December 31, 2021, 2020 and 2019. 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) The fair value of RMBS as of January 1, 2020 includes a cumulative adjustment of $4 million from the adoption of the CECL standard. 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 or 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.

(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 an impairment is identified). The following describes the valuation techniques used in estimating the fair value of our financial assets and liabilities recorded at fair value on a nonrecurring basis. Net Loans Held for Investment Loans held for investment that are recorded at fair value on our consolidated balance sheets on a nonrecurring basis largely consist of impaired loans for which impairment is measured based upon the fair value of the underlying collateral. The fair value is determined using appraisal values that are obtained from independent appraisers, broker pricing opinions or other available market information, adjusted for the estimated cost to sell. Due to the use of significant unobservable inputs, these loans are classified as Level 3 under the fair value hierarchy. Fair value adjustments for individually impaired collateralized loans held for investment are recorded in provision for credit losses in the consolidated statements of income. Loans Held for Sale Loans held for sale for which we have not elected the fair value option are carried at the lower of aggregate cost, net of deferred fees and deferred origination costs, or fair value. These loans held for sale are valued based on market observable inputs and are therefore classified as Level 2. Fair value adjustments to these loans are recorded in other non-interest income in our consolidated statements of income. Other Assets Other assets subject to nonrecurring fair value measurements include equity investments accounted for under the measurement alternative, other repossessed assets and long-lived assets held for sale. The assets held for sale are carried at the lower of the carrying amount or fair value less costs to sell. The fair value is determined based on the appraisal value, listing price of the property or collateral provided by independent appraisers, and is adjusted for the estimated costs to sell. Due to the use of significant unobservable inputs, these assets are classified as Level 3 under the fair value hierarchy. Fair value adjustments for these assets are recorded in other non-interest expense in the consolidated statements of income. The following table presents the carrying value of the assets measured at fair value on a nonrecurring basis and still held as of December 31, 2021 and 2020, and for which a nonrecurring fair value measurement was recorded during the year then ended. Table 16.4: Nonrecurring Fair Value Measurements December 31, 2021 Estimated Fair Value Hierarchy Total (Dollars in millions) Level 2 Level 3 Loans held for investment $ 0 $ 194 $ 194 Loans held for sale 118 0 118 Other assets (1) 0 325 325 Total $ 118 $ 519 $ 637 December 31, 2020 Estimated Fair Value Hierarchy Total (Dollars in millions) Level 2 Level 3 Loans held for investment $ 0 $ 305 $ 305 Other assets (1) 0 175 175 Total $ 0 $ 480 $ 480 __________ (1) As of December 31, 2021, other assets included equity method investments of $50 million, investments accounted for under measurement alternative of $29 million, repossessed assets of $40 million and long-lived assets held for sale of $206 million. 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 13%, and from 0% to 89%, with a weighted average of 14%, as of December 31, 2021 and 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 December 31, 2021 and 2020.

Segment Reporting [Abstract]
Business Segments and Revenue from Contracts with Customers	NOTE 17—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 are included in the Other category. • Credit Card: Consists of our domestic consumer and small business card lending, and international card businesses in Canada and the United Kingdom. • Consumer Banking: Consists of our deposit gathering and lending activities for consumers and small businesses, and national auto lending. • Commercial Banking: Consists of our lending, deposit gathering, capital markets and treasury management services to commercial real estate and commercial and industrial customers. Our customers typically include companies with annual revenues between $20 million and $2 billion. • Other category: Includes the residual impact of the allocation of our centralized Corporate Treasury group activities, such as management of our corporate investment portfolio and asset/liability management, to our business segments. Accordingly, net gains and losses on our investment securities portfolio and certain trading activities are included in the Other category. Other category also includes foreign exchange-rate fluctuations on foreign currency-denominated transactions; unallocated corporate expenses that do not directly support the operations of the business segments or for which the business segments are not considered financially accountable in evaluating their performance, such as certain restructuring charges; certain material items that are non-recurring in nature; offsets related to certain line-item reclassifications; and residual tax expense or benefit to arrive at the consolidated effective tax rate that is not assessed to our primary business segments. 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. The following is additional information on the principles and methodologies used in preparing our business segment results. • Net interest income: Interest income from loans held for investment and interest expense from deposits and other interest-bearing liabilities are reflected within each applicable business segment. Because funding and asset/liability management are managed centrally by our Corporate Treasury group, net interest income for our business segments also includes the results of a funds transfer pricing process that is intended to allocate a cost of funds used or credit for funds provided to all business segment assets and liabilities, respectively, using a matched funding concept. The taxable-equivalent benefit of tax-exempt products is also allocated to each business unit with a corresponding increase in income tax expense. • Non-interest income: Non-interest fees and other revenue associated with loans or customers managed by each business segment and other direct revenues are accounted for within each business segment. • Provision for credit losses: The provision for credit losses is directly attributable to the business segment in accordance with the loans each business segment manages. • Non-interest expense: Non-interest expenses directly managed and incurred by a business segment are accounted for within each business segment. We allocate certain non-interest expenses indirectly incurred by business segments, such as corporate support functions, to each business segment based on various factors, including the actual cost of the services from the service providers, the utilization of the services, the number of employees or other relevant factors. • Goodwill and other intangible assets: Goodwill and other intangible assets that are not directly attributable to business segments are assigned to business segments based on the relative fair value of each segment. Intangible amortization is included in the results of the applicable segment. • Income taxes: Income taxes are assessed for each business segment based on a standard tax rate with the residual tax expense or benefit to arrive at the consolidated effective tax rate included in the Other category. • Loans held for investment: Loans are reported within each business segment based on product or customer type served by that business segment. • Deposits: Deposits are reported within each business segment based on product or customer type served by that business segment. 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 years ended December 31, 2021, 2020 and 2019, selected balance sheet data as of December 31, 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.

Accordingly, we present our Commercial Banking revenue and yields on a taxable-equivalent basis, calculated using the federal statutory tax rate of 21% and state taxes where applicable, with offsetting reductions to the Other category. (2) Total net revenue was reduced by $629 million and $1.1 billion for the years ended December 31, 2021 and 2020, respectively, for credit card finance charges and fees charged off as uncollectible and by $1.4 billion for the year ended December 31, 2019, for the estimated uncollectible amount of billed finance charges and fees and related losses. 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 years ended December 31, 2021, 2020 and 2019.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies, Guarantees and Others	NOTE 18—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 December 31, 2021 and 2020. The carrying value represents our reserve and deferred revenue on legally binding commitments. Table 18.1: Unfunded Lending Commitments Contractual Amount Carrying Value (Dollars in millions) December 31, 2021 December 31, 2020 December 31, 2021 December 31, 2020 Credit card lines $ 368,508 $ 349,594 N/A N/A Other loan commitments (1) 44,572 35,836 $ 125 $ 144 Standby letters of credit and commercial letters of credit (2) 1,419 1,302 24 32 Total unfunded lending commitments $ 414,499 $ 386,732 $ 149 $ 176 __________ (1) Includes $3.9 billion and $1.8 billion of advised lines of credit as of December 31, 2021 and 2020, respectively. (2) These financial guarantees have expiration dates that range from 2021 to 2023 as of December 31, 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 December 31, 2021 and 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 December 31, 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 (primarily in U.S. courts with cases also 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. 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. In the fourth quarter of 2021, the parties agreed to a settlement of the U.S. consumer class action cases for $190 million, which was covered by the Company's legal reserve for this matter. The parties are in the process of seeking the required court approval of the class settlement. 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. The Company’s motion to dismiss the case is pending. 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 have cooperated with these offices and responded 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. 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.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	The accompanying 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. 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 (“VOE”) or a variable interest entity (“VIE”). All significant intercompany account balances and transactions have been eliminated.
Voting Interest Entities	VOEs are entities that have sufficient equity and provide the equity investors voting rights that give them the power to make significant decisions relating to the entity’s operations. Since a controlling financial interest in an entity is typically obtained through ownership of a majority voting interest, we consolidate our majority-owned subsidiaries and other voting interest entities in which we hold, directly or indirectly, more than 50% of the voting rights or where we exercise control through other contractual rights. Investments in which we do not hold a controlling financial interest but have significant influence over the entity’s financial and operating decisions are accounted for under the equity method. If we do not have significant influence, we measure equity investments at fair value with changes in fair value recorded through net income, except those that do not have a readily
Variable Interest Entities	VIEs are entities that, by design, either (i) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties; or (ii) have equity investors that do not have the ability to make significant decisions relating to the entity’s operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity. The entity that is deemed the primary beneficiary of a VIE is required to consolidate the VIE. An entity is deemed to be the primary beneficiary of a VIE if that entity has both (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. In determining whether we are the primary beneficiary of a VIE, we consider both qualitative and quantitative factors regarding the nature, size and form of our involvement with the VIE, such as our role in establishing the VIE and our ongoing rights and responsibilities; our economic interests, including debt and equity investments, servicing fees and other arrangements deemed to be variable interests in the VIE; the design of the VIE, including the capitalization structure, subordination of interests, payment priority, relative share of interests held across various classes within the VIE’s capital structure and the reasons why the interests are held by us. We perform on-going reassessments to evaluate whether changes in an entity’s capital structure or changes in the nature of our involvement with the entity result in a change to the VIE designation or a change to our consolidation conclusion. See “Note 5—Variable Interest Entities and Securitizations” for further details.
Balance Sheet Offsetting of Financial Assets and Liabilities	Derivative contracts that we execute bilaterally in the over-the-counter (“OTC”) market or are centrally cleared are generally governed by enforceable master netting agreements 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 agreements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting agreements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting agreements, we do not offset our derivative positions for balance sheet presentation. See “Note 9—Derivative Instruments and Hedging Activities” for more details. We also elect to present securities purchased or sold under resale or repurchase agreements on a net basis when a legally enforceable master netting agreement exists and other applicable criteria are met. Security collateral received from or pledged to the counterparties are not eligible for netting and are presented gross in our consolidated balance sheet. See “Note 8—Deposits and Borrowings” and “Note 9—Derivative Instruments and Hedging Activities” for more details.
Cash and Cash Equivalents	Cash and cash equivalents include cash and due from banks, interest-bearing deposits and other short-term investments, all of which, if applicable, have stated maturities of three months or less when acquired.
Securities Resale and Repurchase Agreements	Securities purchased under resale agreements and securities loaned or sold under agreements to repurchase, principally U.S. government and agency obligations, are not accounted for as sales but as collateralized financing transactions and recorded at the amounts at which the securities were acquired or sold, plus accrued interest. We continually monitor the market value of these securities and deliver additional collateral to or obtain additional collateral from counterparties, as appropriate. See “Note 8—Deposits and Borrowings” for further details.
Investment Securities	Our investment portfolio consists primarily of the following: U.S. Treasury securities; U.S. government-sponsored enterprise or agency (“Agency”) and non-agency residential mortgage-backed securities (“RMBS”); Agency commercial mortgage-backed securities (“CMBS”); and other securities. The accounting and measurement framework for our investment securities differs depending on the security classification. We classify securities as available for sale or held to maturity based on our investment strategy and management’s assessment of our intent and ability to hold the securities until maturity. We did not have any securities that were classified as held to maturity as of December 31, 2021 and 2020. We report securities available for sale on our consolidated balance sheets at fair value. The amortized cost of investment securities reflects the amount for which the security was acquired, adjusted for accrued interest, amortization of premiums, discounts, and net deferred fees and costs, any applicable fair value hedge accounting adjustments, collection of cash, and charge-offs. Unrealized gains or losses are recorded, net of tax, as a component of accumulated other comprehensive income (“AOCI”). Unamortized premiums, discounts and other basis adjustments for available for sale securities are generally recognized in interest income over the contractual lives of the securities using the effective interest method. However, premiums on certain callable investment securities are amortized to the earliest call date. We record purchases and sales of investment securities available for sale on a trade date basis. Realized gains or losses from the sale of debt securities are computed using the first-in first-out method of identification, and are included in non-interest income in our consolidated statements of income. We elect to present accrued interest for securities available for sale within interest receivable on our consolidated balance sheets. An individual debt security is impaired when the fair value of the security is less than its amortized cost. If we intend to sell an available for sale 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, any allowance for credit losses is reversed through our provision for credit losses and the difference between the amortized cost basis of the security and its fair value is recognized in our consolidated statements of income. For impaired debt securities that we have both the intent and ability to hold, the securities are evaluated to determine if a credit loss exists. The allowance for credit losses on our investment securities is recognized through our provision for credit losses and limited by the unrealized losses of a security measured as the difference between the security’s amortized cost and fair value. See further discussion below under the “Allowance for Credit Losses - Available for Sale Investment Securities” section of this Note. Our investment portfolio also includes certain debt securities that, at the time of purchase, had experienced a more-than-insignificant deterioration in credit quality since origination. Such debt securities are accounted for in accordance with accounting guidance for purchased financial assets with credit deterioration and are herein referred to as purchased credit-deteriorated (“PCD”) securities. PCD securities require the recognition of an allowance for credit losses at the time of acquisition. The allowance for credit losses is not recognized in provision for credit losses. Instead, the purchase price and the initial allowance collectively represent the amortized cost basis of a PCD security. Any non-credit discount or premium at the date of acquisition is amortized into interest income over the remaining life of the security. Subsequent to the date of purchase, we remeasure the allowance for credit losses on the amortized cost basis using the same policies as for other debt securities available for sale and changes are recognized through our provision for credit losses. See further discussion below under the “Allowance for Credit Losses - Available for Sale Investment Securities” section of this Note.
Loans	Our loan portfolio consists of loans held for investment, including loans transferred to our consolidated securitization trusts, and loans held for sale and is divided into three portfolio segments: credit card, consumer banking and commercial banking loans. Credit card loans consist of domestic and international credit card loans. Consumer banking loans consist of auto and retail banking loans. Commercial banking loans consist of commercial and multifamily real estate loans as well as commercial and industrial loans. Loan Classification We classify loans as held for investment or held for sale based on our investment strategy and management’s intent and ability with regard to the loans, which may change over time. The accounting and measurement framework for loans differs depending on the loan classification, whether we elect the fair value option, whether the loans are originated or purchased and whether purchased loans are considered to have experienced a more-than-insignificant deterioration in credit quality since origination. The presentation within the consolidated statements of cash flows is based on management’s intent at acquisition or origination. Cash flows related to loans that are acquired or originated with the intent to hold for investment are included in cash flows from investing activities on our consolidated statements of cash flows. Cash flows related to loans that are acquired or originated with the intent to sell are included in cash flows from operating activities on our consolidated statements of cash flows. Loans Held for Investment Loans that we have the ability and intent to hold for the foreseeable future and loans associated with consolidated securitization transactions are classified as held for investment. Loans classified as held for investment, except for credit card loans, are reported at their amortized cost basis, excluding accrued interest. For these loans, we elect to present accrued interest within interest receivable on our consolidated balance sheets. For credit card loans classified as held for investment, earned finance charges and fees are included in either loans held for investment (if they have been billed to the customer) or interest receivable (if they have not yet been billed to the customer). Interest income is recognized on performing loans on an accrual basis. We defer loan origination fees and direct loan origination costs on originated loans, premiums and discounts on purchased loans and loan commitment fees. We recognize these amounts in interest income as yield adjustments over the life of the loan and/or commitment period using the effective interest method. For credit card loans, loan origination fees and direct loan origination costs are amortized on a straight-line basis over a 12-month period. The amortized cost of loans held for investment is subject to our allowance for credit losses methodology described below under the “Allowance for Credit Losses - Loans Held for Investment” section of this Note. Loans Held for Sale Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Multifamily commercial real estate loans originated with the intent to sell to government-sponsored enterprises are accounted for under the fair value option. We elect the fair value option on these loans as part of our management of interest rate risk along with the corresponding forward sale commitments. Loan origination fees and direct loan origination costs are recognized as incurred and are reported in other non-interest income in the consolidated statements of income. Interest income is calculated based on the loan's stated rate of interest and is reported in interest income in the consolidated statements of income. Fair value adjustments are recorded in other non-interest income in the consolidated statements of income. All other loans classified as held for sale are recorded at the lower of cost or fair value. Loan origination fees, direct loan origination costs and any discounts and premiums are deferred until the loan is sold and are then recognized as part of the total gain or loss on sale. The fair value of loans held for sale is determined on an aggregate portfolio basis for each loan type. Fair value adjustments are recorded in other non-interest income in the consolidated statements of income. If a loan is transferred from held for investment to held for sale, then on the transfer date, any decline in fair value related to credit is recorded as a charge-off and any allowance for credit losses is reversed through our provision for credit losses. The loan is then reclassified to held for sale at its amortized cost at the date of the transfer. A valuation allowance is established, if needed, such that the loan held for sale is recorded at the lower of cost or fair value. Subsequent to transfer, we report write-downs or recoveries in fair value up to the carrying value at the date of transfer and realized gains or losses on loans held for sale in our consolidated statements of income as a component of other non-interest income. We calculate the gain or loss on loan sales as the difference between the proceeds received and the carrying value of the loans sold, net of the fair value of any residual interests retained. Loans Acquired All purchased loans, including loans transferred in a business combination, are initially recorded at fair value, which includes consideration of expected future losses, as of the date of the acquisition. To determine the fair value of loans at acquisition, we estimate discounted contractual cash flows due using an observable market rate of interest, when available, adjusted for factors that a market participant would consider in determining fair value. In determining fair value, contractual cash flows are adjusted to include prepayment estimates based upon historical payment trends, forecasted default rates and loss severities and other relevant factors. The difference between the fair value and the contractual cash flows is recorded as a loan premium or discount, which may relate to either credit or non-credit factors, at acquisition. We account for purchased loans under the accounting guidance for purchased financial assets with credit deterioration when, at the time of purchase, the loans have experienced a more-than-insignificant deterioration in credit quality since origination. We refer to these loans which are accounted for under accounting guidance for purchased financial assets with more-than-insignificant deterioration in credit quality since origination as “PCD loans”. We recognize an allowance for credit losses on purchased loans that have not experienced a more-than-insignificant deterioration in credit quality since origination at the time of purchase through earnings in a manner that is consistent with originated loans. The policies relating to the allowance for credit losses on loans is described below in the “Allowance for Credit Losses - Loans Held for Investment” section of this Note. Loan Modifications and Restructurings As part of our loss mitigation efforts, we may provide modifications to a borrower experiencing financial difficulty to improve long-term collectability of the loan and to avoid the need for foreclosure or repossession of collateral, if any. Our loan modifications typically include short-term payment deferrals, an extension of the loan term, a reduction in the interest rate, a reduction in the loan balance, or a combination of these concessions. A loan modification in which a concession is granted to a borrower experiencing financial difficulty is accounted for and reported as a troubled debt restructuring (“TDR”). See “Note 3—Loans” for additional information on our loan modifications and restructurings, including those in response to the COVID-19 pandemic. Delinquent and Nonperforming Loans The entire balance of a loan is considered contractually delinquent if the minimum required payment is not received by the first statement cycle date equal to or following the due date specified on the customer’s billing statement. Delinquency is reported on loans that are 30 or more days past due. Interest and fees continue to accrue on past due loans until the date the loan is placed on nonaccrual status, if applicable. For loan modifications, delinquency and nonaccrual status are reported in accordance with the revised terms of the loans. We generally place loans on nonaccrual status when we believe the collectability of interest and principal is not reasonably assured. Nonperforming loans generally include loans that have been placed on nonaccrual status. Loans classified as held for sale are excluded from nonperforming classification consideration. Our policies for classifying loans as nonperforming, by loan category, are as follows: • C redit card loans: As permitted by regulatory guidance issued by the Federal Financial Institutions Examination Council (“FFIEC”), our policy is generally to exempt credit card loans from being classified as nonperforming, as these loans are generally charged off in the period the account becomes 180 days past due. Consistent with industry conventions, we generally continue to accrue interest and fees on delinquent credit card loans until the loans are charged off. • Consumer banking loans: We classify consumer banking loans as nonperforming when we determine that the collectability of all interest and principal on the loan is not reasonably assured, generally when the loan becomes 90 days past due. • Commercial banking loans : We classify commercial banking loans as nonperforming as of the date we determine that the collectability of all interest and principal on the loan is not reasonably assured. • Modified loans and troubled debt restructurings: Modified loans, including TDRs, that are current at the time of the restructuring remain in accrual status if there is demonstrated performance prior to the restructuring and continued performance under the modified terms is expected. Otherwise, the modified loan is classified as nonperforming. Interest and fees accrued but not collected at the date a loan is placed on nonaccrual status are reversed against earnings. In addition, the amortization of deferred loan fees, costs, premiums and discounts is suspended. Interest and fee income are subsequently recognized only upon the receipt of cash payments. However, if there is doubt regarding the ultimate collectability of loan principal, cash received is generally applied against the principal balance of the loan. Nonaccrual loans are generally returned to accrual status when all principal and interest is current and repayment of the remaining contractual principal and interest is reasonably assured, or when the loan is both well-secured and in the process of collection and collectability is no longer doubtful. Charge-Offs We charge off loans when we determine that the loan is uncollectible. The amortized cost basis, excluding accrued interest, is charged off as a reduction to the allowance for credit losses based on the time frames presented below. Accrued interest on loans other than credit card loans determined to be uncollectible is reversed as a reduction of interest income when the loan is classified as nonperforming. For credit card loans, accrued interest is charged off simultaneously with the charge off of other components of amortized cost and as a reduction of interest income. When received, recoveries of previously charged off amounts are recorded as an increase to the allowance for credit losses (see the “Allowance for Credit Losses - Loans Held for Investment” section of this Note for information on how we account for expected recoveries). Costs to recover charged off loans are recorded as collection expense and included in our consolidated statements of income as a component of other non-interest expense as incurred. Our charge-off time frames by loan type are presented below. • Credit card loans : We generally charge off credit card loans in the period the account becomes 180 days past due. We charge off delinquent credit card loans for which revolving privileges have been revoked as part of loan workout when the account becomes 120 days past due. Credit card loans in bankruptcy are generally charged off by the end of the month following 30 days after the receipt of a complete bankruptcy notification from the bankruptcy court. Credit card loans of deceased account holders are generally charged off 5 days after receipt of notification. • Consumer banking loans: We generally charge off consumer banking loans at the earlier of the date when the account is a specified number of days past due or upon repossession of the underlying collateral. Our charge-off period for auto loans is 120 days past due. Small business banking loans generally charge off at 120 days past due based on the date the amortized cost basis is deemed uncollectible. Auto loans that have not been previously charged off where the borrower has filed for bankruptcy and the loan has not been reaffirmed charge off in the period that the loan is 60 days from the bankruptcy notification date, regardless of delinquency status. Auto loans that have not been previously charged off and have been discharged under Chapter 7 bankruptcy are charged off at the end of the month in which the bankruptcy discharge occurs. Remaining consumer loans generally are charged off within 40 days of receipt of notification from the bankruptcy court. Consumer loans of deceased account holders are charged off by the end of the month following 60 days of receipt of notification. • Commercial banking loans: We charge off commercial loans in the period we determine that the amortized cost basis is uncollectible.
Allowance for Credit Losses	Allowance for Credit Losses - Available for Sale Investment Securities We maintain an allowance for credit losses (“allowance”) that represents management’s current estimate of expected credit losses over the contractual terms of our investment securities classified as available for sale. When an investment security available for sale is impaired due to credit factors, we recognize a provision for credit losses in our consolidated statements of income and an allowance for credit losses on our consolidated balance sheets. Credit losses recognized in the allowance for credit losses are limited to the amount by which the investment security’s amortized cost basis exceeds its fair value. Investment securities in unrealized gain positions do not have an allowance for credit losses as the investment security could be sold at its fair value to prevent realization of credit losses. We exclude accrued interest from the fair value and amortized cost basis of an investment security for purposes of measuring impairment. Charge-offs of uncollectible amounts of investment securities are deducted from the allowance for credit losses. For certain of our securities available for sale, we have determined that there is no risk of impairment due to credit factors. These investment securities include high quality debt instruments that are issued and guaranteed by the United States government and its agencies, certain government-sponsored enterprises, and certain foreign sovereign governments or supranational organizations. Management performs periodic assessments to reevaluate this conclusion by considering any changes in historical losses, current conditions, and reasonable and supportable forecasts. We evaluate impairment on a quarterly basis at the individual security level and determine whether any portion of the decline in fair value is due to a credit loss. We make this determination through the use of quantitative and qualitative analyses. Our qualitative analysis includes factors such as the extent to which fair value is less than amortized cost, any changes in the security’s credit rating, past defaults or delayed payments, and adverse conditions impacting the security or issuer. A credit loss exists to the extent that management does not expect to recover the amortized cost basis. For investment securities which require further assessment, we perform a quantitative analysis using a discounted cash flow methodology and compare the present value of expected future cash flows from the security available for sale to the security’s amortized cost basis. Projected future cash flows reflect management’s best estimate and are based on our understanding of past events, current conditions, reasonable and supportable forecasts, and are discounted by the security’s effective interest rate adjusted for prepayments. The allowance for credit losses for investment securities reflects the difference by which the amortized cost basis exceeds the present value of future cash flows and is limited to the amount by which the security’s amortized cost exceeds its fair value. See “Note 2—Investment Securities” for additional information. Allowance for Credit Losses - Loans Held for Investment We maintain an allowance for credit losses (“allowance”) that represents management’s current estimate of expected credit losses over the contractual terms of our loans held for investment. We measure the allowance on a quarterly basis through consideration of past events, including historical experience, current conditions and reasonable and supportable forecasts. We measure current expected credit losses over the contractual terms of our loans. The contractual terms are adjusted for expected prepayments but are not extended for renewals or extensions, except when an extension or renewal arises from a borrower option that is not unconditionally cancellable or through a TDR that is reasonably expected to occur. We aggregate loans sharing similar risk characteristics into pools for purposes of measuring expected credit losses. Pools are reassessed periodically to confirm that all loans within each pool continue to share similar risk characteristics. Expected credit losses for loans that do not share similar risk characteristics with other financial assets are measured individually. Expected recoveries of amounts previously charged off or expected to be charged off are recognized within the allowance, with a corresponding reduction to our provision for credit losses. At times expected recoveries may result in a negative allowance. We limit the allowance recovery expectations to amounts previously charged off and expected to be charged off. Charge-offs of uncollectible amounts result in a reduction to the allowance and recoveries of previously charged off amounts result in an increase to 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. Significant judgment is applied to the development and duration of reasonable and supportable forecasts used in our estimation of lifetime losses. We estimate expected credit losses over the duration of those forecasts and then revert, on a rational and systematic basis, to historical losses at each relevant loss component of the estimate. Expected losses for contractual terms extending beyond the reasonable and supportable forecast and reversion periods are based on those historical losses. 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. Management’s judgment may involve an assessment of current and forward-looking conditions including but not limited to changes in lending policies and procedures, nature and volume of the portfolio, external factors, and uncertainty as it relates to economic, model or forecast risks, where not already captured in the modeled results. Expected credit losses for collateral-dependent loans are based on the fair value of the underlying collateral. When we intend to liquidate the collateral, the fair value of the collateral is adjusted for expected costs to sell. A loan is deemed to be a collateral-dependent loan when (i) we determine foreclosure or repossession of the underlying collateral is probable, or (ii) foreclosure or repossession is not probable, but the borrower is experiencing financial difficulty and we expect repayment to be provided substantially through the operation or sale of the collateral. The allowance for a collateral-dependent loan reflects the difference between the loan’s amortized cost basis and the fair value (less selling costs, where applicable) of the loan's underlying collateral. Our credit card and consumer banking loan portfolios consist of smaller-balance, homogeneous loans. The consumer banking loan portfolio is divided into two primary portfolio segments: auto loans and retail banking loans. The credit card and consumer banking loan portfolios are further divided by our business units into groups based on common risk characteristics, such as origination year, contract type, interest rate, borrower credit score and geography. The commercial banking loan portfolio is primarily composed of larger-balance, non-homogeneous loans. These loans are subject to reviews that result in internal risk ratings. In assessing the risk rating of a particular commercial banking loan, among the factors we consider are the financial condition of the borrower, geography, collateral performance, historical loss experience and industry-specific information that management believes is relevant in determining and measuring expected credit losses. Subjective assessment and interpretation are involved. Emphasizing one factor over another or considering additional factors could impact the risk rating assigned to that commercial banking loan. For consumer banking and commercial banking loans, the contractual period typically does not include renewals or extensions because the renewals and extensions are generally not at the borrower’s exclusive option to exercise. Management has determined that the undrawn credit exposure that is associated with our credit card loans is unconditionally cancellable. For this reason, expected credit losses are measured based on the drawn balance at each quarterly measurement date, but not on the undrawn exposure. Because credit card loans do not have a defined contractual life, management estimates both the volume and application of payments to determine a contractual life of the drawn balance at the measurement date over which expected credit losses are developed for credit card loans. With the exception of credit card loans, we have made a policy election to not measure an allowance on accrued interest for loans held for investment because we reverse uncollectible accrued interest in a timely manner. See the “Delinquent and Nonperforming Loans” and “Charge-Offs - Loans” sections of this Note for information on what we consider timely. For credit card loans, we do not make this election, as we reserve for uncollectible accrued interest relating to credit card loans in the allowance. The allowance related to credit card and consumer banking loans assessed on a pooled basis is based on a modeled calculation, which is supplemented by management judgment as described above. Because of the homogeneous nature of our consumer loan portfolios, the allowance is based on the aggregated portfolio segment evaluations. The allowance is established through a process that begins with estimates of historical losses in each pool based upon various statistical analyses, with adjustments for current conditions and reasonable and supportable forecasts of conditions, which includes expected economic conditions. Loss forecast models are utilized to estimate expected credit losses and consider several portfolio indicators including, but not limited to, expected economic conditions, historical loss experience, account seasoning, the value of collateral underlying secured loans, estimated foreclosures or defaults based on observable trends, delinquencies, bankruptcy filings, unemployment, borrower credit scores and general business trends. Management believes these factors are relevant in estimating expected credit losses and also considers an evaluation of overall portfolio credit quality based on indicators such as changes in our credit evaluation, underwriting and collection management policies, the effect of other external factors such as competition and legal and regulatory requirements, general economic conditions and business trends, and uncertainties in forecasting and modeling techniques used in estimating our allowance. The allowance related to commercial banking loans assessed on a pooled basis is based on our historical loss experience for loans with similar risk characteristics and consideration of the current credit quality of the portfolio, which is supplemented by management judgment as described above. These are adjusted for current conditions, and reasonable and supportable forecasts of conditions likely to cause future losses which vary from historical levels. We apply internal risk ratings to commercial banking loans, which we use to assess credit quality and derive a total loss estimate based on an estimated probability of default (“default rate”) and loss given default (“loss severity”). Management may also apply judgment to adjust the loss factors derived, taking into consideration both quantitative and qualitative factors, including general economic conditions, industry-specific and geographic trends, portfolio concentrations, trends in internal credit quality indicators, and current and past underwriting standards that have occurred but are not yet reflected in the historical data underlying our loss estimates. The allowance related to smaller-balance homogeneous credit card and consumer banking loans whose terms have been modified in a TDR is calculated on a pool basis using historical loss experience, adjusted for current conditions and reasonable and supportable forecasts of conditions likely to cause future losses which vary from historical levels for the respective class of assets. The allowance related to consumer banking loans that are assessed at a loan-level is determined based on key considerations that include the borrower’s overall financial condition, resources and payment history, prospects for support from financially responsible guarantors, and when applicable, the estimated realizable value of any collateral. The allowance related to commercial banking loans that are assessed at a loan-level is generally determined in accordance with our policy for estimating expected credit losses for collateral-dependent loans as described above. Off-balance sheet credit exposures In addition to the allowance, we also measure expected credit losses related to unfunded lending commitments that are not unconditionally cancellable in our Commercial Banking business. This reserve is measured using the same measurement objectives as the allowance for loans held for investment and is recorded within other liabilities on our consolidated balance sheets. These commitments are segregated by risk according to our internal risk rating scale, which we use to assess credit quality and derive an expected credit loss estimate. We assess these risk classifications, taking into consideration both quantitative and qualitative factors, including historical loss experience, adjusted for current conditions and reasonable and supportable forecasts of conditions likely to cause future losses which vary from historical levels, and utilization assumptions to estimate the reserve for unfunded lending commitments. Expected credit losses are not measured on unfunded lending commitments that are unconditionally cancellable, including all of our unfunded credit card and consumer banking lending commitments and certain of our unfunded commercial banking lending commitments.
Securitization of Loans	Our loan securitization activities primarily involve the securitization of credit card and auto loans, which provides a source of funding for us. See “Note 5—Variable Interest Entities and Securitizations” for additional details. Loan securitization involves the transfer of a pool of loan receivables from our portfolio to a trust. The trust then sells undivided interests in the pool of loan receivables to third-party investors through the issuance of debt securities and transfers the proceeds from the debt issuance to us as consideration for the loan receivables transferred. The debt securities are collateralized by the loan receivables transferred from our portfolio. We remove loans from our consolidated balance sheets if securitizations qualify as sales to unconsolidated VIEs, recognize assets retained and liabilities assumed at fair value and record a gain or loss on the transferred loans. Alternatively, if the transfer does not qualify as a sale but instead is considered a secured borrowing, the assets will remain on our consolidated balance sheets with an offsetting liability recognized for the amount of proceeds received.
Premises and Equipment	Premises and Equipment Premises and equipment, including leasehold improvements, are carried at cost less accumulated depreciation and amortization. Land is carried at cost. We capitalize direct costs incurred during the application development stage of internally developed software projects. Depreciation and amortization expenses are calculated using the straight-line method over the estimated useful lives of the assets. Useful lives for premises and equipment are estimated as follows: Premises and Equipment Useful Lives Buildings and improvements 5-39 years Furniture and equipment 3-10 years Computer software 3 years Leasehold improvements Lesser of the useful life or the remaining lease term Expenditures for maintenance and repairs are expensed as incurred and gains or losses upon disposition are recognized in our consolidated statements of income as realized. See “Note 7—Premises, Equipment and Leases” for additional information.
Leases	Lease classification is determined at inception for all lease transactions with an initial term greater than one year. Operating leases are included as right-of-use (“ROU”) assets within other assets, and operating lease liabilities are classified as other liabilities on our consolidated balance sheets. Finance leases are included in premises and equipment, and other borrowings on our consolidated balance sheets. Our operating lease expense is included in occupancy and equipment within non-interest expense in our consolidated statements of income. Lease expense for minimum lease payments are recognized on a straight-line basis over the lease term. See “Note 7—Premises, Equipment and Leases” for additional information.
Goodwill and Other Intangible Assets	Goodwill represents the excess of the acquisition price of an acquired business over the fair value of assets acquired and liabilities assumed and is assigned to one or more reporting units at the date of acquisition. A reporting unit is defined as an operating segment, or a business unit that is one level below an operating segment. We have four reporting units: Credit Card, Auto, Other Consumer Banking and Commercial Banking. Goodwill is not amortized but is tested for impairment at the reporting unit level annually or more frequently if adverse circumstances indicate that it is more likely than not that the carrying amount of a reporting unit exceeds its fair value. These indicators could include a sustained, significant decline in the Company’s stock price, a decline in expected future cash flows, significant disposition activity, a significant adverse change in the economic or business environment, and the testing for recoverability of a significant asset group, among others. Intangible assets with finite useful lives are amortized on either an accelerated or straight-line basis over their estimated useful lives and are evaluated for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable. See “Note 6—Goodwill and Other Intangible Assets” for additional information.
Mortgage Servicing Rights	Mortgage servicing rights (“MSRs”) are initially recorded at fair value when mortgage loans are sold or securitized in the secondary market and the right to service these loans is retained for a fee. Commercial MSRs are subsequently accounted for under the amortization method. We evaluate for impairment as of each reporting date and recognize any impairment in other non-interest income. See “Note 6—Goodwill and Other Intangible Assets” for additional information.
Foreclosed Property and Repossessed Asset	Foreclosed property and repossessed assets obtained through our lending activities typically include commercial real estate or personal property, such as automobiles, and are recorded at net realizable value. For foreclosed property and repossessed assets, we generally reclassify the loan to repossessed assets upon repossession of the property in satisfaction of the loan. Net realizable value is the estimated fair value of the underlying collateral less estimated selling costs and is based on appraisals, when available. Subsequent to initial recognition, foreclosed property and repossessed assets are recorded at the lower of our initial cost basis or net realizable value, which is routinely monitored and updated. Any changes in net realizable value and gains or losses realized from disposition of the property are recorded in other non-interest expense. See “Note 16—Fair Value Measurement” for details.
Restricted Equity Investments	We have investments in Federal Home Loan Bank (“FHLB”) stock and in Federal Reserve Bank stock. These investments, which are included in other assets on our consolidated balance sheets, are not marketable, are carried at cost, and are reviewed for impairment if there is any indicator of impairment.
Litigation	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. Professional service fees, including lawyers’ and experts’ fees, expected to be incurred in connection with a loss contingency are expensed as services are provided. See “Note 18—Commitments, Contingencies, Guarantees and Others” for additional information.
Customer Rewards Reserve	We offer products, primarily credit cards, which include programs that allow members to earn rewards based on account activity that can be redeemed for cash (primarily in the form of statement credits), gift cards, travel, or covering eligible charges. The amount of reward that a customer earns varies based on the terms and conditions of the rewards program and product. When rewards are earned by a customer, rewards expense is generally recorded as an offset to interchange income, with a corresponding increase to the customer rewards reserve. The customer rewards reserve is computed based on the estimated future cost of earned rewards that are expected to be redeemed and is reduced as rewards are redeemed. In estimating the customer rewards reserve, we consider historical redemption and spending behavior, as well as the terms and conditions of the current rewards programs, among other factors. We expect the vast majority of all rewards earned will eventually be redeemed. The customer rewards reserve, which is included in other liabilities on our consolidated balance sheets, totaled $6.2 billion and $5.4 billion as of December 31, 2021 and 2020, respectively.
Revenue Recognition	Interest Income and Fees Interest income and fees on loans and investment securities are recognized based on the contractual provisions of the underlying arrangements. Loan origination fees,costs,premiums and discounts on loans held for investment are deferred and generally amortized into interest income as yield adjustments over the contractual life and/or commitment period using the effective interest method. Costs deferred include, among other things, incentives paid to our network of auto dealers for loan referrals. In certain circumstances, we elect to factor prepayment estimates into the calculation of the constant effective yield necessary to apply the interest method. Prepayment estimates are based on historical prepayment data, existing and forecasted interest rates, and economic data. For credit card loans, loan origination fees and direct loan origination costs are amortized on a straight-line basis over a 12-month period. Unamortized premiums, discounts and other basis adjustments on investment securities are generally recognized in interest income over the contractual lives of the securities using the effective interest method. However, premiums for certain callable investment securities are amortized to the earliest call date. Finance charges and fees on credit card loans are recorded in revenue when earned and presented on our consolidated balance sheets within either loan receivables (if they have been billed to the customer) or interest receivable (if they have not yet been billed to the customer). Finance charges and fees on credit card loans are not recorded after the account is charged off. Annual membership fees are classified as service charges and other customer-related fees in our consolidated statements of income and are deferred and amortized into income over 12 months on a straight-line basis. Interchange Income Interchange income generally represents fees for standing ready to authorize and providing settlement on credit and debit card transactions processed through the MasterCard® (“MasterCard”) and Visa® (“Visa”) interchange networks. The levels and structure of interchange rates set by MasterCard and Visa can vary based on cardholder purchase volumes, among other factors. We recognize interchange income upon settlement. See “Note 17—Business Segments and Revenue from Contracts with Customers” for additional details. Card Partnership Agreements We have contractual agreements with certain retailers and other partners to provide lending and other services to mutual customers. We primarily issue private-label and cobrand credit card loans to these customers over the terms of the partnership agreements. Certain partners assist in or perform marketing activities on our behalf and promote our products and services to their customers. As compensation for providing these services, we often pay royalties, bounties or other special bonuses to these partners. Our payments to partners are generally recorded as reductions of revenue or as marketing expenses, depending on their nature. Our credit card partnership agreements may also provide for profit or revenue sharing payments which are presented as a reduction of the related revenue line item(s) when owed to the partner. When a partner agrees to share a portion of the credit losses associated with the partnership, we evaluate the contractual provisions for the loss share payments as well as applicable accounting guidance to determine whether to present the sharing of losses on a gross or net basis in our consolidated financial statements. When loss sharing amounts due from partners are presented on a net basis, they are recorded as a reduction to our provision for credit losses in our consolidated statements of income and reduce the charge-off amounts that we report. The allowance for credit losses attributable to these portfolios is also reduced by the expected reimbursements from these partners for loss sharing amounts. See “Note 4—Allowance for Credit Losses and Reserve for Unfunded Lending Commitments” for additional information related to our loss sharing arrangements. Collaborative Arrangements A collaborative arrangement is a contractual arrangement that involves a joint operating activity between two or more parties that are active participants in the activity. These parties are exposed to significant risks and rewards based upon the economic success of the joint operating activity. We assess each of our partnership agreements with profit, revenue or loss sharing payments to determine if a collaborative arrangement exists and, if so, how revenue generated from third parties, costs incurred and transactions between participants in the collaborative arrangement should be accounted for and reported on our consolidated financial statements. We currently have one partnership agreement that meets the definition of a collaborative agreement. We share a fixed percentage of revenues, consisting of finance charges and late fees, with the partner, and the partner is required to reimburse us for a fixed percentage of credit losses incurred. Revenues and losses related to the partner’s credit card program and partnership agreement are reported on a net basis in our consolidated financial statements. Revenue sharing amounts attributable to the partner are recorded as an offset against total net revenue in our consolidated statements of income. Interest income was reduced by $1.0 billion, $1.1 billion and $1.0 billion in December 31, 2021, 2020 and 2019, respectively, for amounts earned by the partner pursuant to the partnership agreement. The impact of all of our loss sharing arrangements that are presented on a net basis is included in “Note 4—Allowance for Credit Losses and Reserve for Unfunded Lending Commitments.”
Stock-based Compensation	We are authorized to issue stock–based compensation to employees and directors in various forms, primarily as restricted stock units (“RSUs”), performance share units and stock options. In addition, we also issue cash equity units and cash-settled restricted stock units which are not counted against the common shares reserved for issuance or available for issuance because they are settled in cash. For awards settled in shares, we generally recognize compensation expense on a straight-line basis over the award’s requisite service period based on the fair value of the award at the grant date. If an award settled in shares contains a performance condition with graded vesting, we recognize compensation expense using the accelerated attribution method. Equity units and restricted stock units that are cash-settled are accounted for as liability awards which results in quarterly expense fluctuations based on changes in our stock price through the date that the awards are settled. Awards to participants that are eligible for retirement or become eligible during the vesting period are expensed immediately or over the time period between the grant date and when the participant becomes retirement eligible, respectively. Stock-based compensation expense is included in salaries and associate benefits in the consolidated statements of income. For RSUs and performance share units, the fair value of stock-based compensation used in determining compensation expense will generally equal the fair market value of our common stock on the date of grant. Stock-based compensation expense for equity classified stock options is based on the grant date fair value, which is estimated using a Black-Scholes option pricing model. Certain share-settled awards have discretionary vesting conditions which result in the remeasurement of these awards at fair value each reporting period and the potential for compensation expense to fluctuate with changes in our stock price. See “Note 13—Stock-Based Compensation Plans” for additional details.
Marketing Expenses	Marketing expense includes the cost of our various promotional efforts to attract and retain customers such as advertising, promotional materials, and certain customer incentives, including spend-based bonuses. We expense marketing costs as incurred.
Income Taxes	We recognize the current and deferred tax consequences of all transactions that have been recognized in the financial statements using the provisions of the enacted tax laws. Current income tax expense represents our estimated taxes to be paid or refunded for the current period and includes income tax expense related to our uncertain tax positions, as well as tax-related interest and penalties. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. We record valuation allowances to reduce deferred tax assets to the amount that is more likely than not to be realized. We record the effect of remeasuring deferred tax assets and liabilities due to a change in tax rates or laws as a component of income tax expense related to continuing operations for the period in which the change is enacted. We subsequently release income tax effects stranded in AOCI using a portfolio approach. Income tax benefits are recognized when, based on their technical merits, they are more likely than not to be sustained upon examination. The amount recognized is the largest amount of benefit that is more likely than not to be realized upon settlement. See “Note 15—Income Taxes” for additional details
Earnings Per Share	Earnings per share is calculated and reported under the “two-class” method. The “two-class” method is an earnings allocation method under which earnings per share is calculated for each class of common stock and participating security considering both dividends declared or accumulated and participation rights in undistributed earnings as if all such earnings had been distributed during the period. We have unvested share-based payment awards which have a right to receive non-forfeitable dividends, which are deemed to be participating securities. We calculate basic earnings per share by dividing net income, after deducting dividends on preferred stock and participating securities as well as undistributed earnings allocated to participating securities, by the average number of common shares outstanding during the period, net of any treasury shares. We calculate diluted earnings per share in a similar manner after consideration of the potential dilutive effect of common stock equivalents on the average number of common shares outstanding during the period. Common stock equivalents include warrants, stock options, restricted stock awards and units, and performance share awards and units. Common stock equivalents are calculated based upon the treasury stock method using an average market price of common shares during the period. Dilution is not considered when a net loss is reported. Common stock equivalents that have an antidilutive effect are excluded from the computation of diluted earnings per share. See “Note 12—Earnings Per Common Share” for additional details.
Derivatives Instruments and Hedging Activities	All derivative financial instruments, whether designated for hedge accounting or not, are reported at their fair value on our consolidated balance sheets as either assets or liabilities, with consideration of legally enforceable master netting agreements that allow us to net settle positive and negative positions and offset cash collateral with the same counterparty. We report net derivatives in a gain position, or derivative assets, on our consolidated balance sheets as a component of other assets. We report net derivatives in a loss position, or derivative liabilities, on our consolidated balance sheets as a component of other liabilities. See “Note 9—Derivative Instruments and Hedging Activities” for additional details.
Fair Value	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 whether the inputs to the valuation techniques used to measure fair value are observable or unobservable. Fair value measurement of a financial asset or liability is assigned to 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 requires that we maximize the use of observable inputs and minimize the use of unobservable inputs in determining fair value. The accounting guidance also 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 to fair value in the consolidated statements of income. See “Note 16—Fair Value Measurement” for additional information.
Accounting for Acquisitions	We account for business combinations under the acquisition method of accounting. Under the acquisition method, tangible and intangible identifiable assets acquired, liabilities assumed and any noncontrolling interest in the acquiree are recorded at fair value as of the acquisition date, with limited exceptions. Transaction costs and costs to restructure the acquired company are expensed as incurred. Goodwill is recognized as the excess of the acquisition price over the estimated fair value of the identifiable net assets acquired. Likewise, if the fair value of the net assets acquired is greater than the acquisition price, a bargain purchase gain is recognized and recorded in other non-interest income. If the acquired set of activities and assets do not meet the accounting definition of a business, the transaction is accounted for as an asset acquisition. In an asset acquisition, the assets acquired are recorded at the purchase price plus any transaction costs incurred and no goodwill is recognized.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Balance Sheet Offsetting of Financial Assets and Liabilities	Derivative contracts that we execute bilaterally in the over-the-counter (“OTC”) market or are centrally cleared are generally governed by enforceable master netting agreements 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 agreements for balance sheet presentation where a right of setoff exists. For derivative contracts entered into under master netting agreements for which we have not been able to confirm the enforceability of the setoff rights, or those not subject to master netting agreements, we do not offset our derivative positions for balance sheet presentation. See “Note 9—Derivative Instruments and Hedging Activities” for more details. We also elect to present securities purchased or sold under resale or repurchase agreements on a net basis when a legally enforceable master netting agreement exists and other applicable criteria are met. Security collateral received from or pledged to the counterparties are not eligible for netting and are presented gross in our consolidated balance sheet. See “Note 8—Deposits and Borrowings” and “Note 9—Derivative Instruments and Hedging Activities” for more details.

Schedule of Level 3 Inputs Reconciliation	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 years ended December 31, 2021, 2020 and 2019. 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.

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 16.3: 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 $ 258 Discounted cash flows (vendor pricing) Yield 0-21% 5-40% 1-11% 30-100% 3% 11% 2% 65% CMBS 9 Discounted cash flows (vendor pricing) Yield 1-2% 1% Other assets: Retained interests in securitizations (2) 41 Discounted cash flows Life of receivables (months) 29-36 9-18% 2-8% 3-4% 72-151% N/A Net derivative assets (liabilities) 19 Discounted cash flows Swap rates 1-2% 2% 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.
