Accounting Changes and Error Corrections [Abstract]
Accounting Changes	Note 2 Accounting Changes Reference Interest Rate Transition In March 2020, the FASB issued accounting guidance, providing temporary optional expedients and exceptions to the guidance in United States generally accepted accounting principles on contract modifications and hedge accounting, to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates. Under the guidance, a company can elect not to apply certain modification accounting requirements to contracts affected by reference rate transition, if certain criteria are met. A company that makes this election would not be required to remeasure the contracts at the modification date or reassess a previous accounting determination. This guidance also permits a company to elect various optional expedients that would allow it to continue applying hedge accounting for hedging relationships affected by reference rate transition, if certain criteria are met. The guidance is effective upon issuance and generally can be applied through December 31, 2022. The Company is in the process of evaluating and applying, as applicable, the optional expedients and exceptions in accounting for eligible contract modifications, eligible existing hedging relationships and new hedging relationships available through December 31, 2022. The adoption of this guidance has not had, and is expected to continue to not have, a material impact on the Company’s financial statements.

Included in these amounts were securities where the Company and certain counterparties have agreements granting the counterparties the right to sell or pledge the securities. Investment securities securing these types of arrangements had a fair value of $625 million at June 30, 2021, and $402 million at December 31, 2020.

U.S. Treasury and agencies securities and agency mortgage-backed securities are issued, guaranteed or otherwise supported by the United States government. The Company’s obligations of state and political subdivisions are generally high grade. Accordingly, the Company does not consider these unrealized losses to be credit-related and an allowance for credit losses is not necessary. In general, the issuers of the investment securities are contractually prohibited from prepayment at less than par, and the Company did not pay significant purchase premiums for these investment securities. At June 30, 2021, the Company had no plans to sell investment securities with unrealized losses, and believes it is more likely than not it would not be required to sell such investment securities before recovery of their amortized cost.

Originated loans are reported at the principal amount outstanding, net of unearned interest and deferred fees and costs, and any partial charge-offs recorded. Net unearned interest and deferred fees and costs amounted to $789 million at June 30, 2021 and $763 million at December 31, 2020. All purchased loans are recorded at fair value at the date of purchase. Beginning January 1, 2020, the Company evaluates purchased loans for more-than-insignificant deterioration at the date of purchase in accordance with applicable authoritative accounting guidance. Purchased loans that have experienced more-than-insignificant deterioration from origination are considered purchased credit deteriorated loans. All other purchased loans are considered non-purchased Allowance for Credit Losses Beginning January 1, 2020, the allowance for credit losses is established for current expected credit losses on the Company’s loan and lease portfolio, including unfunded credit commitments. The allowance considers expected losses for the remaining lives of the applicable assets, inclusive of expected recoveries. The allowance for credit losses is increased through provisions charged to earnings and reduced by net charge-offs. Management evaluates the appropriateness of the allowance for credit losses on a quarterly basis. Multiple economic scenarios are considered over a three-year reasonable and supportable forecast period, which includes increasing consideration of historical loss experience over years two and three. These economic scenarios are constructed with interrelated projections of multiple economic variables, and loss estimates are produced that consider the historical correlation of those economic variables with credit losses. After the forecast period, the Company fully reverts to long-term historical loss experience, adjusted for prepayments and characteristics of the current loan and lease portfolio, to estimate losses over the remaining life of the portfolio. The economic scenarios are updated at least quarterly and are designed to provide a range of reasonable estimates from better to worse than current expectations. Scenarios are weighted based on the Company’s expectation of economic conditions for the foreseeable future and reflect significant judgment and consideration of uncertainties that exist. Final loss estimates also consider factors affecting credit losses not reflected in the scenarios, due to the unique aspects of current conditions and expectations. These factors may include, but are not limited to, loan servicing practices, regulatory guidance, and/or fiscal and monetary policy actions. The allowance recorded for credit losses utilizes forward-looking expected loss models to consider a variety of factors affecting lifetime credit losses. These factors include, but are not limited to, macroeconomic variables such as unemployment rate, real estate prices, gross domestic product levels and corporate bonds spreads, as well as loan and borrower characteristics, such as internal risk ratings on commercial loans and consumer credit scores, delinquency status, collateral type and available valuation information, consideration of end-of-term charged-off than $ million in the commercial lending segment is based on an analysis utilizing expected cash flows discounted using the original effective interest rate, the observable market price of the loan, or the fair value of the c The allowance recorded for Troubled Debt Restructuring (“TDR”) loans in the consumer lending segment is determined on a homogenous pool basis utilizing expected cash flows discounted using the original effective interest rate of the pool. TDRs generally do not include loan modifications granted to customers resulting directly from the economic effects of the COVID-19 pandemic, who were otherwise in current payment status. The expected cash flows on TDR loans consider subsequent payment defaults since modification, the borrower’s ability to pay under the restructured terms, and the timing and amount of payments. The allowance for collateral-dependent loans in the consumer lending segment is determined based on the fair value of the collateral less costs to sell. With respect to the commercial lending segment, TDRs may be collectively evaluated for impairment where observed performance history, including defaults, is a primary driver of the loss allocation. For commercial TDRs individually evaluated for impairment, attributes of the borrower are the primary factors in determining the allowance for credit losses. However, historical loss experience is also incorporated into the allowance methodology applied to this category of loans. Beginning January 1, 2020, when a loan portfolio is purchased, the acquired loans are divided into those considered purchased with more than insignificant credit deterioration (“PCD”) and those not considered purchased with more than insignificant credit deterioration. An allowance is established for each population and considers product mix, risk characteristics of the portfolio, bankruptcy experience, delinquency status and refreshed LTV ratios when possible. The allowance established for purchased loans not considered PCD is recognized through provision expense upon acquisition, whereas the allowance established for loans considered PCD at acquisition is offset by an increase in the basis of the acquired loans. Any subsequent increases and decreases in the allowance related to purchased loans, regardless of PCD status, are recognized through provision expense, with charge-offs charged to the allowance. The Company did not have a material amount of PCD loans included in its loan portfolio at June 30, 2021. The Company’s methodology for determining the appropriate allowance for credit losses also considers the imprecision inherent in the methodologies used and allocated to the various loan portfolios. As a result, amounts determined under the methodologies described above, are adjusted by management to consider the potential impact of other qualitative factors not captured in the quantitative model adjustments which include, but are not limited to the following: model imprecision, imprecision in economic scenario assumptions, and emerging risks related to either changes in the environment that are affecting specific portfolios, or changes in portfolio concentrations over time that may affect model performance. The consideration of these items results in adjustments to allowance amounts included in the Company’s allowance for credit losses for each loan portfolio. The Company also assesses the credit risk associated with off-balance off-balance Prior to January 1, 2020, the allowance for credit losses was established based on an incurred loss model. The allowance recorded for loans in the commercial lending segment was based on the migration analysis of commercial loans and actual loss experience. The allowance recorded for loans in the consumer lending segment was determined on a homogenous pool basis and primarily included consideration of delinquency status and historical losses. In addition to the amounts determined under the methodologies described above, management also considered the potential impact of qualitative factors. Activity in the allowance for credit losses by portfolio class was as follows: Three Months Ended June 30 (Dollars in Millions) Commercial Commercial Residential Credit Other Total 2021 Balance at beginning of period $1,932 $1,532 $539 $1,952 $1,005 $6,960 Add Provision for credit losses (67 ) (123 ) (71 ) 87 4 (170 ) Deduct Loans charged-off 58 4 5 192 55 314 Less recoveries of loans charged-off (31 ) (4 ) (15 ) (44 ) (40 ) (134 ) Net loan charge-offs (recoveries) 27 – (10 ) 148 15 180 Balance at end of period $1,838 $1,409 $478 $1,891 $ 994 $6,610 2020 Balance at beginning of period $2,240 $ 841 $412 $2,012 $1,085 $6,590 Add Provision for credit losses 516 450 218 373 180 1,737 Deduct Loans charged-off 125 23 3 265 106 522 Less recoveries of loans charged-off (14 ) (1 ) (6 ) (36 ) (28 ) (85 ) Net loan charge-offs (recoveries) 111 22 (3 ) 229 78 437 Balance at end of period $2,645 $1,269 $633 $2,156 $1,187 $7,890 Six Months Ended June 30 (Dollars in Millions) Commercial Commercial Residential Credit Other Total 2021 Balance at beginning of period $2,423 $1,544 $573 $2,355 $1,115 $8,010 Add Provision for credit losses (502 ) (142 ) (110 ) (172 ) (71 ) (997 ) Deduct Loans charged-off 144 14 10 382 138 688 Less recoveries of loans charged-off (61 ) (21 ) (25 ) (90 ) (88 ) (285 ) Net loan charge-offs (recoveries) 83 (7 ) (15 ) 292 50 403 Balance at end of period $1,838 $1,409 $478 $1,891 $ 994 $6,610 2020 Balance at beginning of period $1,484 $799 $433 $1,128 $647 $4,491 Add Change in accounting principle (a) 378 (122 ) (30 ) 872 401 1,499 Provision for credit losses 968 612 228 619 303 2,730 Deduct Loans charged-off 213 23 11 539 227 1,013 Less recoveries of loans charged-off (28 ) (3 ) (13 ) (76 ) (63 ) (183 ) Net loan charge-offs (recoveries) 185 20 (2 ) 463 164 830 Balance at end of period $2,645 $1,269 $633 $2,156 $1,187 $7,890 (a) Effective January 1, 2020, the Company adopted accounting guidance which changed impairment recognition of financial instruments to a model that is based on expected losses rather than incurred losses. The decrease in the allowance for credit losses from December 31, 2020 to June 30, 2021 reflected factors affecting economic conditions during the first six months of 2021, including the enactment of additional benefits from government stimulus programs, vaccine availability in the United States and reduced levels of new COVID-19 cases, which have contributed to an economic recovery. Credit Quality The credit quality of the Company’s loan portfolios is assessed as a function of net credit losses, levels of nonperforming assets and delinquencies, and credit quality ratings as defined by the Company. For all loan portfolio classes, loans are considered past due based on the number of days delinquent except for monthly amortizing loans which are classified delinquent based upon the number of contractually required payments not made (for example, two missed payments is considered 30 days delinquent). When a loan is placed on nonaccrual status, unpaid accrued interest is reversed, reducing interest income in the current period. Commercial lending segment loans are generally placed on nonaccrual status when the collection of principal and interest has become 90 days past due or is otherwise considered doubtful. Commercial lending segment loans are generally fully or partially charged down to the fair value of the collateral securing the loan, less costs to sell, when the loan is placed on nonaccrual. Consumer lending segment loans are generally charged-off 1-4 value of the collateral securing the loan, less costs to sell, at 180 days past due. Residential mortgage loans and lines in a first lien position are placed on nonaccrual status in instances where a partial charge-off 1-4 charged-off. charged-off 1-4 charged-off charged-off charge-off. For all loan classes, interest payments received on nonaccrual loans are generally recorded as a reduction to a loan’s carrying amount while a loan is on nonaccrual and are recognized as interest income upon payoff of the loan. However, interest income may be recognized for interest payments if the remaining carrying amount of the loan is believed to be collectible. In certain circumstances, loans in any class may be restored to accrual status, such as when a loan has demonstrated sustained repayment performance or no amounts are past due and prospects for future payment are no longer in doubt; or when the loan becomes well secured and is in the process of collection. Loans where there has been a partial charge-off charged-off) The following table provides a summary of loans by portfolio class, including the delinquency status of those that continue to accrue interest, and those that are nonperforming: Accruing (Dollars in Millions) Current 30-89 Days 90 Days or Nonperforming (b) Total June 30, 2021 Commercial $ 103,019 $ 171 $ 40 $ 291 $103,521 Commercial real estate 38,423 32 3 312 38,770 Residential mortgages (a) 72,830 174 118 244 73,366 Credit card 21,506 157 153 – 21,816 Other retail 59,003 203 62 171 59,439 Total loans $ 294,781 $ 737 $376 $1,018 $296,912 December 31, 2020 Commercial $ 102,127 $ 314 $ 55 $ 375 $102,871 Commercial real estate 38,676 183 2 450 39,311 Residential mortgages (a) 75,529 244 137 245 76,155 Credit card 21,918 231 197 – 22,346 Other retail 56,466 318 86 154 57,024 Total loans $ 294,716 $1,290 $477 $1,224 $297,707 (a) At June 30, 2021, $1.3 billion of loans 30–89 days past due and $1.7 billion of loans 90 days or more past due purchased from Government National Mortgage Association (“GNMA”) mortgage pools whose repayments are insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs, were classified as current, compared with $1.4 billion and $1.8 billion at December 31, 2020, respectively. (b) Substantially all nonperforming loans at June 30, 2021 and December 31, 2020, had an associated allowance for credit losses. The Company recognized interest income on nonperforming loans of $4 million and $6 million for the three months ended June 30, 2021 and 2020, respectively, and $7 million and $10 million for the six months ended June 30, 2021 and 2020, respectively. At June 30, 2021, the amount of foreclosed residential real estate held by the Company, and included in other real estate owned (“OREO”), was $17 million, compared with $23 million at December 31, 2020. These amounts excluded $24 million and $33 million at June 30, 2021 and December 31, 2020, respectively, of foreclosed residential real estate related to mortgage loans whose payments are primarily insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs. In addition, the amount of residential mortgage loans secured by residential real estate in the process of foreclosure at June 30, 2021 and December 31, 2020, was $865 million and $1.0 billion, respectively, of which $697 million and $812 million, respectively, related to loans purchased from Government National Mortgage Association (“GNMA”) mortgage pools whose repayments are insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs. The Company classifies its loan portfolio classes using internal credit quality ratings on a quarterly basis. These ratings include pass, special mention and classified, and are an important part of the Company’s overall credit risk management process and evaluation of the allowance for credit losses. Loans with a pass rating represent those loans not classified on the Company’s rating scale for problem credits, as minimal credit risk has been identified. Special mention loans are those loans that have a potential weakness deserving management’s close attention. Classified loans are those loans where a well-defined weakness has been identified that may put full collection of contractual cash flows at risk. It is possible that others, given the same information, may reach different reasonable conclusions regarding the credit quality rating classification of specific loans.

(a) Classified rating on consumer loans primarily based on delinquency status. (b) At June 30, 2021, $1.7 billion of GNMA loans 90 days or more past due and $1.2 billion of restructured GNMA loans whose repayments are insured by the Federal Housing Administration or guaranteed by the United States Department of Veterans Affairs were classified with a pass rating, compared with $1.8 billion and $1.4 billion at December 31, 2020, respectively. (c) All credit card loans are considered revolving loans. Troubled Debt Restructurings In certain circumstances, the Company may modify the terms of a loan to maximize the collection of amounts due when a borrower is experiencing financial difficulties or is expected to experience difficulties in the near-term. Concessionary modifications are classified as TDRs unless the modification results in only an insignificant delay in payments to be received. The Company recognizes interest on TDRs if the borrower complies with the revised terms and conditions as agreed upon with the Company and has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles, which is generally six months or greater. To the extent a previous restructuring was insignificant, the Company considers the cumulative effect of past restructurings related to the receivable when determining whether a current restructuring is a TDR. The following table provides a summary of loans modified as TDRs for the periods presented by portfolio class: 2021 2020 (Dollars in Millions) Number Pre-Modification Post-Modification Number Pre-Modification Post-Modification Three Months Ended June 30 Commercial 526 $ 12 $ 13 1,139 $144 $115 Commercial real estate 30 38 41 38 39 39 Residential mortgages 360 141 140 121 24 24 Credit card 5,050 31 31 6,168 37 38 Other retail 468 18 17 374 9 8 Total loans, excluding loans purchased from GNMA mortgage pools 6,434 240 242 7,840 253 224 Loans purchased from GNMA mortgage pools 478 67 69 1,009 142 138 Total loans 6,912 $307 $311 8,849 $395 $362 Six Months Ended June 30 Commercial 1,230 $ 87 $ 73 2,138 $243 $216 Commercial real estate 86 124 112 65 60 60 Residential mortgages 696 245 244 211 34 34 Credit card 10,836 64 65 14,583 83 85 Other retail 1,793 55 49 1,029 24 22 Total loans, excluding loans purchased from GNMA mortgage pools 14,641 575 543 18,026 444 417 Loans purchased from GNMA mortgage pools 1,037 154 158 2,913 408 398 Total loans 15,678 $729 $701 20,939 $852 $815 Residential mortgages, home equity and second mortgages, and loans purchased from GNMA mortgage pools in the table above include trial period arrangements offered to customers during the periods presented. The post-modification balances for these loans reflect the current outstanding balance until a permanent modification is made. In addition, the post-modification balances typically include capitalization of unpaid accrued interest and/or fees under the various modification programs. At June 30, 2021, 6 residential mortgages, 7 home equity and second mortgage loans and 68 loans purchased from GNMA mortgage pools with outstanding balances of $1 million, $1 million and $10 million, respectively, were in a trial period and have estimated post-modification balances of $1 million, $1 million and $10 million, respectively, assuming permanent modification occurs at the end of the trial period. The Company has implemented certain restructuring programs that may result in TDRs. However, many of the Company’s TDRs are also determined on a case-by-case For the commercial lending segment, modifications generally result in the Company working with borrowers on a case-by-case Modifications for the consumer lending segment are generally part of programs the Company has initiated. The Company modifies residential mortgage loans under Federal Housing Administration, United States Department of Veterans Affairs, or its own internal programs. Under these programs, the Company offers qualifying homeowners the opportunity to permanently modify their loan and achieve more affordable monthly payments by providing loan concessions. These concessions may include adjustments to interest rates, conversion of adjustable rates to fixed rates, extension of maturity dates or deferrals of payments, capitalization of accrued interest and/or outstanding advances, or in limited situations, partial forgiveness of loan principal. In most instances, participation in residential mortgage loan restructuring programs requires the customer to complete a short-term trial period. A permanent loan modification is contingent on the customer successfully completing the trial period arrangement, and the loan documents are not modified until that time. The Company reports loans in a trial period arrangement as TDRs and continues to report them as TDRs after the trial period. Credit card and other retail loan TDRs are generally part of distinct restructuring programs providing customers experiencing financial difficulty with modifications whereby balances may be amortized up to 60 months, and generally include waiver of fees and reduced interest rates. In addition, the Company considers secured loans to consumer borrowers that have debt discharged through bankruptcy where the borrower has not reaffirmed the debt to be TDRs. Loan modifications or concessions granted to borrowers resulting directly from the effects of the COVID-19 pandemic, who were otherwise in current payment status, are generally not considered to be TDRs. As of June 30, 2021, approximately $5.4 billion of loan modifications included on the Company’s consolidated balance sheet related to borrowers impacted by the COVID-19 pandemic, consisting primarily of payment deferrals.

These loans had aggregate outstanding balances of $2 million and $6 million for the three months and six months ended June 30, 2021, respectively. As of June 30, 2021, the Company had $129 million of commitments to lend additional funds to borrowers whose terms of their outstanding owed balances have been modified in TDRs.

Accounting Policies [Abstract]
Accounting for Transfers and Servicing of Financial Assets and Variable Interest Entities	Note 5 Accounting for Transfers and Servicing of Financial Assets and Variable Interest Entities The Company transfers financial assets in the normal course of business. The majority of the Company’s financial asset transfers are residential mortgage loan sales primarily to government-sponsored enterprises (“GSEs”), transfers of tax-advantaged For loans sold under participation agreements, the Company also considers whether the terms of the loan participation agreement meet the accounting definition of a participating interest. With the exception of servicing and certain performance-based guarantees, the Company’s continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses. Any gain or loss on sale depends on the previous carrying amount of the transferred financial assets, the consideration received, and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests that continue to be held by the Company are initially recognized at fair value. For further information on mortgage servicing rights (“MSRs”), refer to Note 6. On a limited basis, the Company may acquire and package high-grade corporate bonds for select corporate customers, in which the Company generally has no continuing involvement with these transactions. Additionally, the Company is an authorized GNMA issuer and issues GNMA securities on a regular basis. The Company has no other asset securitizations or similar asset-backed financing arrangements that are off-balance The Company also provides financial support primarily through the use of waivers of trust and investment management fees associated with various unconsolidated registered money market funds it manages. The Company provided $70 million and $13 million of support to the funds during the three months ended June 30, 2021 and 2020, respectively, and $117 million and $21 million during the six months ended June 30, 2021 and 2020, respectively. The Company is involved in various entities that are considered to be variable interest entities (“VIEs”). The Company’s investments in VIEs are primarily related to investments promoting affordable housing, community development and renewable energy sources. Some of these tax-advantaged tax-advantaged The Company is not required to consolidate VIEs in which it has concluded it does not have a controlling financial interest, and thus is not the primary beneficiary. In such cases, the Company does not have both the power to direct the entities’ most significant activities and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIEs. The Company’s investments in these unconsolidated VIEs are carried in other assets on the Consolidated Balance Sheet. The Company’s unfunded capital and other commitments related to these unconsolidated VIEs are generally carried in other liabilities on the Consolidated Balance Sheet. The Company’s maximum exposure to loss from these unconsolidated VIEs include the investment recorded on the Company’s Consolidated Balance Sheet, net of unfunded capital commitments, and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. While the Company believes potential losses from these investments are remote, the maximum exposure was determined by assuming a scenario where the community-based business and housing projects completely fail and do not meet certain government compliance requirements resulting in recapture of the related tax credits. The following table provides a summary of investments in community development and tax-advantaged (Dollars in Millions) June 30, 2021 December 31, Investment carrying amount $ 5,012 $ 5,378 Unfunded capital and other commitments 2,257 2,334 Maximum exposure to loss 10,579 11,219 The Company also has noncontrolling financial investments in private investment funds and partnerships considered to be VIEs, which are not consolidated. The Company’s recorded investment in these entities, carried in other assets on the Consolidated Balance Sheet, was approximately $39 million at June 30, 2021 and $35 million at December 31, 2020. The maximum exposure to loss related to these VIEs was $80 million at June 30, 2021 and $57 million at December 31, 2020, representing the Company’s investment balance and its unfunded commitments to invest additional amounts. The Company’s individual net investments in unconsolidated VIEs, which exclude any unfunded capital commitments, ranged from less than $1 million to $75 million at June 30, 2021, compared with less than $1 million to $78 million at December 31, 2020. The Company is required to consolidate VIEs in which it has concluded it has a controlling financial interest. The Company sponsors entities to which it transfers its interests in tax-advantaged tax-advantaged In addition, the Company sponsors a municipal bond securities tender option bond program. The Company controls the activities of the program’s entities, is entitled to the residual returns and provides liquidity and remarketing arrangements to the program. As a result, the Company has consolidated the program’s entities. At June 30, 2021, $1.7 billion of available-for-sale available-for-sale

Mortgage Servicing Rights

Text Block [Abstract]
Mortgage Servicing Rights	Note 6 Mortgage Servicing Rights The Company capitalizes MSRs as separate assets when loans are sold and servicing is retained. MSRs may also be purchased from others. The Company carries MSRs at fair value, with changes in the fair value recorded in earnings during the period in which they occur. The Company serviced $215.0 billion of residential mortgage loans for others at June 30, 2021, and $211.8 billion at December 31, 2020, including subserviced mortgages with no corresponding MSR asset. Included in mortgage banking revenue are the MSR fair value changes arising from market rate and model assumption changes, net of the value change in derivatives used to economically hedge MSRs. These changes resulted in a net loss of $27 million and a net gain of $24 million for the three months ended June 30, 2021 and 2020, respectively, and a net loss of $147 million and a net gain of $49 million for the six months ended June 30, 2021 and 2020, respectively. Loan servicing and ancillary fees, not including valuation changes, included in mortgage banking revenue were $178 million and $174 million for the three months ended June 30, 2021 and 2020, respectively, and $353 million and $360 million for the six months end June 30, 2021 and 2020, respectively. Changes in fair value of capitalized MSRs are summarized as follows: Three Months Ended Six Months Ended (Dollars in Millions) 2021 2020 2021 2020 Balance at beginning of period $ 2,787 $ 1,887 $ 2,210 $ 2,546 Rights purchased 11 3 27 8 Rights capitalized 293 190 612 391 Rights sold (a) 1 1 1 2 Changes in fair value of MSRs Due to fluctuations in market interest rates (b) (232 ) (64 ) 254 (807 ) Due to revised assumptions or models (c) (37 ) 27 (139 ) 44 Other changes in fair value (d) (110 ) (204 ) (252 ) (344 ) Balance at end of period $ 2,713 $ 1,840 $ 2,713 $ 1,840 (a) MSRs sold include those having a negative fair value, resulting from the loans being severely delinquent. (b) Includes changes in MSR value associated with changes in market interest rates, including estimated prepayment rates and anticipated earnings on escrow deposits. (c) Includes changes in MSR value not caused by changes in market interest rates, such as changes in assumed cost to service, ancillary income and option adjusted spread, as well as the impact of any model changes. (d) Primarily the change in MSR value from passage of time and cash flows realized (decay), but also includes the impact of changes to expected cash flows not associated with changes in market interest rates, such as the impact of delinquencies. The estimated sensitivity to changes in interest rates of the fair value of the MSR portfolio and the related derivative instruments was as follows: June 30, 2021 December 31, 2020 (Dollars in Millions) Down Down Down Up Up Up Down Down Down Up Up Up MSR portfolio $ (571 ) $ (307 ) $ (158 ) $ 156 $ 302 $ 547 $ (442 ) $ (271 ) $ (150 ) $ 169 $ 343 $ 671 Derivative instrument hedges 592 298 149 (142 ) (281 ) (552 ) 523 281 145 (149 ) (304 ) (625 ) Net sensitivity $ 21 $ (9 ) $ (9 ) $ 14 $ 21 $ (5 ) $ 81 $ 10 $ (5 ) $ 20 $ 39 $ 46 The fair value of MSRs and their sensitivity to changes in interest rates is influenced by the mix of the servicing portfolio and characteristics of each segment of the portfolio. The Company’s servicing portfolio consists of the distinct portfolios of government-insured mortgages, conventional mortgages and Housing Finance Agency (“HFA”) mortgages. The servicing portfolios are predominantly comprised of fixed-rate agency loans with limited adjustable-rate or jumbo mortgage loans. The HFA servicing portfolio is comprised of loans originated under state and local housing authority program guidelines which assist purchases by first-time or low- government- and conventional-insured mortgages. A summary of the Company’s MSRs and related characteristics by portfolio was as follows: June 30, 2021 December 31, 2020 (Dollars in Millions) HFA Government Conventional (d) Total HFA Government Conventional (d) Total Servicing portfolio (a) $ 39,564 $ 22,698 $ 149,660 $ 211,922 $ 40,396 $ 25,474 $ 143,085 $ 208,955 Fair value $ 478 $ 285 $ 1,950 $ 2,713 $ 406 $ 261 $ 1,543 $ 2,210 Value (bps) (b) 121 126 130 128 101 102 108 106 Weighted-average servicing fees (bps) 35 40 30 32 35 40 30 32 Multiple (value/servicing fees) 3.40 3.15 4.30 3.96 2.87 2.56 3.55 3.26 Weighted-average note rate 4.23 % 3.82 % 3.54 % 3.70 % 4.43 % 3.91 % 3.78 % 3.92 % Weighted-average age (in years) 3.8 5.9 3.6 3.9 3.8 5.6 4.2 4.3 Weighted-average expected prepayment (constant prepayment rate) 12.0 % 14.4 % 10.3 % 11.1 % 14.1 % 18.0 % 13.8 % 14.4 % Weighted-average expected life (in years) 6.4 5.2 6.7 6.5 5.6 4.3 5.5 5.4 Weighted-average option adjusted spread (c) 7.7 % 7.3 % 6.4 % 6.8 % 7.7 % 7.3 % 6.2 % 6.6 % (a) Represents principal balance of mortgages having corresponding MSR asset.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 12 Derivative Instruments In the ordinary course of business, the Company enters into derivative transactions to manage various risks and to accommodate the business requirements of its customers. The Company recognizes all derivatives on the Consolidated Balance Sheet at fair value in other assets or in other liabilities. On the date the Company enters into a derivative contract, the derivative is designated as either a fair value hedge, cash flow hedge, net investment hedge, or a designation is not made as it is a customer-related transaction, an economic hedge for asset/liability risk management purposes or another stand-alone derivative created through the Company’s operations (“free-standing derivative”). When a derivative is designated as a fair value, cash flow or net investment hedge, the Company performs an assessment, at inception and, at a minimum, quarterly thereafter, to determine the effectiveness of the derivative in offsetting changes in the value or cash flows of the hedged item(s). Fair Value Hedges These derivatives are interest rate swaps the Company uses to hedge the change in fair value related to interest rate changes of its underlying available-for-sale Cash Flow Hedges These derivatives are interest rate swaps the Company uses to hedge the forecasted cash flows from its underlying variable-rate debt. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income (loss) until the cash flows of the hedged items are realized. If a derivative designated as a cash flow hedge is terminated or ceases to be highly effective, the gain or loss in other comprehensive income (loss) is amortized to earnings over the period the forecasted hedged transactions impact earnings. If a hedged forecasted transaction is no longer probable, hedge accounting is ceased and any gain or loss included in other comprehensive income (loss) is reported in earnings immediately, unless the forecasted transaction is at least reasonably possible of occurring, whereby the amounts remain within other comprehensive income (loss). At June 30, 2021, the Company had $107 million (net-of-tax) (net-of-tax) both (net-of-tax ) and six Net Investment Hedges The Company uses forward commitments to sell specified amounts of certain foreign currencies, and non-derivative non-derivative Other Derivative Positions The Company enters into free-standing derivatives to mitigate interest rate risk and for other risk management purposes.

The Company measures that credit risk using a credit valuation adjustment and includes it within the fair value of the derivative. The Company manages counterparty credit risk through diversification of its derivative positions among various counterparties, by entering into derivative positions that are centrally cleared through clearinghouses, by entering into master netting arrangements and, where possible, by requiring collateral arrangements. A master netting arrangement allows two counterparties, who have multiple derivative contracts with each other, the ability to net settle amounts under all contracts, including any related collateral, through a single payment and in a single currency. Collateral arrangements generally require the counterparty to deliver collateral (typically cash or U.S. Treasury and agency securities) equal to the Company’s net derivative receivable, subject to minimum transfer and credit rating requirements.

Netting Arrangements for Certain Financial Instruments and Securities Financing Activities	Note 13 Netting Arrangements for Certain Financial Instruments and Securities Financing Activities The Company’s derivative portfolio consists of bilateral over-the-counter over-the-counter As part of the Company’s treasury and broker-dealer operations, the Company executes transactions that are treated as securities sold under agreements to repurchase or securities purchased under agreements to resell, both of which are accounted for as collateralized financings. Securities sold under agreements to repurchase include repurchase agreements and securities loaned transactions. Securities purchased under agreements to resell include reverse repurchase agreements and securities borrowed transactions. For securities sold under agreements to repurchase, the Company records a liability for the cash received, which is included in short-term borrowings on the Consolidated Balance Sheet. For securities purchased under agreements to resell, the Company records a receivable for the cash paid, which is included in other assets on the Consolidated Balance Sheet. Securities transferred to counterparties under repurchase agreements and securities loaned transactions continue to be recognized on the Consolidated Balance Sheet, are measured at fair value, and are included in investment securities or other assets. Securities received from counterparties under reverse repurchase agreements and securities borrowed transactions are not recognized on the Consolidated Balance Sheet unless the counterparty defaults. The securities transferred under repurchase and reverse repurchase transactions typically are U.S. Treasury and agency securities, residential agency mortgage-backed securities or corporate debt securities. The securities loaned or borrowed typically are corporate debt securities traded by the Company’s broker-dealer subsidiary. In general, the securities transferred can be sold, repledged or otherwise used by the party in possession. No restrictions exist on the use of cash collateral by either party. Repurchase/reverse repurchase and securities loaned/borrowed transactions expose the Company to counterparty risk. The Company manages this risk by performing assessments, independent of business line managers, and establishing concentration limits on each counterparty. Additionally, these transactions include collateral arrangements that require the fair values of the underlying securities to be determined daily, resulting in cash being obtained or refunded to counterparties to maintain specified collateral levels. The following table summarizes the maturities by category of collateral pledged for repurchase agreements and securities loaned transactions: (Dollars in Millions) Overnight and Less Than 30-89 Greater Than Total June 30, 2021 Repurchase agreements U.S. Treasury and agencies $ 273 $ – $ – $ – $ 273 Residential agency mortgage-backed securities 618 – – – 618 Corporate debt securities 622 – – – 622 Total repurchase agreements 1,513 – – – 1,513 Securities loaned Corporate debt securities 208 – – – 208 Total securities loaned 208 – – – 208 Gross amount of recognized liabilities $ 1,721 $ – $ – $ – $ 1,721 December 31, 2020 Repurchase agreements U.S. Treasury and agencies $ 472 $ – $ – $ – $ 472 Residential agency mortgage-backed securities 398 – – – 398 Corporate debt securities 560 – – – 560 Total repurchase agreements 1,430 – – – 1,430 Securities loaned Corporate debt securities 218 – – – 218 Total securities loaned 218 – – – 218 Gross amount of recognized liabilities $ 1,648 $ – $ – $ – $ 1,648 The Company executes its derivative, repurchase/reverse repurchase and securities loaned/borrowed transactions under the respective industry standard agreements. These agreements include master netting arrangements that allow for multiple contracts executed with the same counterparty to be viewed as a single arrangement. This allows for net settlement of a single amount on a daily basis. In the event of default, the master netting arrangement provides for close-out The Company has elected to offset the assets and liabilities under netting arrangements for the balance sheet presentation of the majority of its derivative counterparties. The netting occurs at the counterparty level, and includes all assets and liabilities related to the derivative contracts, including those associated with cash collateral received or delivered.

Fair Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Note 14 Fair Values of Assets and Liabilities The Company uses fair value measurements for the initial recording of certain assets and liabilities, periodic remeasurement of certain assets and liabilities, and disclosures. Derivatives, trading and available-for-sale lower-of-cost-or-fair Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. The Company groups its assets and liabilities measured at fair value into a three-level hierarchy for valuation techniques used to measure financial assets and financial liabilities at fair value. This hierarchy is based on whether the valuation inputs are observable or unobservable. These levels are: • Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 1 includes U.S. Treasury securities, as well as exchange-traded instruments. • Level 2 — Observable 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 2 includes debt securities that are traded less frequently than exchange-traded instruments and which are typically valued using third party pricing services; derivative contracts and other assets and liabilities, including securities, whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data; and MLHFS whose values are determined using quoted prices for similar assets or pricing models with inputs that are observable in the market or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category includes MSRs and certain derivative contracts. Valuation Methodologies The valuation methodologies used by the Company to measure financial assets and liabilities at fair value are described below. In addition, the following section includes an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Where appropriate, the descriptions include information about the valuation models and key inputs to those models. During the six months ended June 30, 2021 and 2020, there were no significant changes to the valuation techniques used by the Company to measure fair value. Available-For-Sale When quoted market prices for identical securities are available in an active market, these prices are used to determine fair value and these securities are classified within Level 1 of the fair value hierarchy. Level 1 investment securities include U.S. Treasury and exchange-traded securities. For other securities, quoted market prices may not be readily available for the specific securities. When possible, the Company determines fair value based on market observable information, including quoted market prices for similar securities, inactive transaction prices, and broker quotes. These securities are classified within Level 2 of the fair value hierarchy. Level 2 valuations are generally provided by a third party pricing service. Level 2 investment securities are predominantly agency mortgage-backed securities, certain other asset-backed securities, obligations of state and political subdivisions and agency debt securities. Mortgage Loans Held For Sale MLHFS measured at fair value, for which an active secondary market and readily available market prices exist, are initially valued at the transaction price and are subsequently valued by comparison to instruments with similar collateral and risk profiles. MLHFS are classified within Level 2. Included in mortgage banking revenue were net gains of $98 million and $81 million for the three months ended June 30, 2021 and 2020, respectively, and a net loss of $117 million and a net gain of $174 million for the six months ended June 30, 2021 and 2020, respectively, from the changes to fair value of these MLHFS under fair value option accounting guidance. Changes in fair value due to instrument specific credit risk were immaterial. Interest income for MLHFS is measured based on contractual interest rates and reported as interest income on the Consolidated Statement of Income. Electing to measure MLHFS at fair value reduces certain timing differences and better matches changes in fair value of these assets with changes in the value of the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting. Mortgage Servicing Rights MSRs are valued using a discounted cash flow methodology, and are classified within Level 3. The Company determines fair value of the MSRs by projecting future cash flows for different interest rate scenarios using prepayment rates and other assumptions, and discounts these cash flows using a risk adjusted rate based on option adjusted spread levels. There is minimal observable market activity for MSRs on comparable portfolios and, therefore, the determination of fair value requires significant management judgment. Refer to Note 6 for further information on MSR valuation assumptions. Derivatives The majority of derivatives held by the Company are executed over-the-counter The Company also has other derivative contracts that are created through its operations, including commitments to purchase and originate mortgage loans and swap agreements executed in conjunction with the sale of a portion of its Class B common and preferred shares of Visa Inc. (the “Visa swaps”). The mortgage loan commitments are valued by pricing models that include market observable and unobservable inputs, which result in the commitments being classified within Level 3 of the fair value hierarchy. The unobservable inputs include assumptions about the percentage of commitments that actually become a closed loan and the MSR value that is inherent in the underlying loan value. The Visa swaps require payments by either the Company or the purchaser of the Visa Inc. Class B common and preferred shares when there are changes in the conversion rate of the Visa Inc. Class B common and preferred shares to Visa Inc. Class A common and preferred shares, respectively, as well as quarterly payments to the purchaser based on specified terms of the agreements. Management reviews and updates the Visa swaps fair value in conjunction with its review of Visa Inc. related litigation contingencies, and the associated escrow funding. The expected litigation resolution impacts the Visa Inc. Class B common share to Visa Inc. Class A common share conversion rate, as well as the ultimate termination date for the Visa swaps. Accordingly, the Visa swaps are classified within Level 3. Refer to Note 15 for further information on the Visa Inc. restructuring and related card association litigation. Significant Unobservable Inputs of Level 3 Assets and Liabilities The following section provides information to facilitate an understanding of the uncertainty in the fair value measurements for the Company’s Level 3 assets and liabilities recorded at fair value on the Consolidated Balance Sheet. This section includes a description of the significant inputs used by the Company and a description of any interrelationships between these inputs. The discussion below excludes nonrecurring fair value measurements of collateral value used for impairment measures for loans and OREO. These valuations utilize third party appraisal or broker price opinions, and are classified as Level 3 due to the significant judgment involved. Mortgage Servicing Rights The significant unobservable inputs used in the fair value measurement of the Company’s MSRs are expected prepayments and the option adjusted spread that is added to the risk-free rate to discount projected cash flows. Significant increases in either of these inputs in isolation would have resulted in a significantly lower fair value measurement. Significant decreases in either of these inputs in isolation would have resulted in a significantly higher fair value measurement. There is no direct interrelationship between prepayments and option adjusted spread. Prepayment rates generally move in the opposite direction of market interest rates. Option adjusted spread is generally impacted by changes in market return requirements. The following table shows the significant valuation assumption ranges for MSRs at June 30, 2021: Minimum Maximum Weighted- Expected prepayment 3 % 15 % 11 % Option adjusted spread 6 11 7 (a) Determined based on the relative fair value of the related mortgage loans serviced. Derivatives The Company has two distinct Level 3 derivative portfolios: (i) the Company’s commitments to purchase and originate mortgage loans that meet the requirements of a derivative and (ii) the Company’s asset/liability and customer-related derivatives that are Level 3 due to unobservable inputs related to measurement of risk of nonperformance by the counterparty. In addition, the Company’s Visa swaps are classified within Level 3. The significant unobservable inputs used in the fair value measurement of the Company’s derivative commitments to purchase and originate mortgage loans are the percentage of commitments that actually become a closed loan and the MSR value that is inherent in the underlying loan value. A significant increase in the rate of loans that close would have resulted in a larger derivative asset or liability. A significant increase in the inherent MSR value would have resulted in an increase in the derivative asset or a reduction in the derivative liability. Expected loan close rates and the inherent MSR values are directly impacted by changes in market rates and will generally move in the same direction as interest rates. The following table shows the significant valuation assumption ranges for the Company’s derivative commitments to purchase and originate mortgage loans at June 30, 2021: Minimum Maximum Weighted- Expected loan close rate 6 % 100 % 74 % Inherent MSR value (basis points per loan) 47 187 116 (a) Determined based on the relative fair value of the related mortgage loans. The significant unobservable input used in the fair value measurement of certain of the Company’s asset/liability and customer-related derivatives is the credit valuation adjustment related to the risk of counterparty nonperformance. A significant increase in the credit valuation adjustment would have resulted in a lower fair value measurement. A significant decrease in the credit valuation adjustment would have resulted in a higher fair value measurement. The credit valuation adjustment is impacted by changes in market rates, volatility, market implied credit spreads, and loss recovery rates, as well as the Company’s assessment of the counterparty’s credit position. At June 30, 2021, the minimum, maximum and weighted-average credit valuation adjustment as a percentage of the net fair value of the counterparty’s derivative contracts prior to adjustment was 0 percent, 94 percent and 1 percent, respectively. The significant unobservable inputs used in the fair value measurement of the Visa swaps are management’s estimate of the probability of certain litigation scenarios occurring, and the timing of the resolution of the related litigation loss estimates in excess, or shortfall, of the Company’s proportional share of escrow funds. An increase in the loss estimate or a delay in the resolution of the related litigation would have resulted in an increase in the derivative liability. A decrease in the loss estimate or an acceleration of the resolution of the related litigation would have resulted in a decrease in the derivative liability.

Guarantees and Contingent Liabilities	Note 15 Guarantees and Contingent Liabilities Visa Restructuring and Card Association Litigation The Company’s payment services business issues credit and debit cards and acquires credit and debit card transactions through the Visa U.S.A. Inc. card association or its affiliates (collectively “Visa”). In 2007, Visa completed a restructuring and issued shares of Visa Inc. common stock to its financial institution members in contemplation of its initial public offering (“IPO”) completed in the first quarter of 2008 (the “Visa Reorganization”). As a part of the Visa Reorganization, the Company received its proportionate number of shares of Visa Inc. common stock, which were subsequently converted to Class B shares of Visa Inc. (“Class B shares”). Visa U.S.A. Inc. (“Visa U.S.A.”) and MasterCard International (collectively, the “Card Brands”) are defendants in antitrust lawsuits challenging the practices of the Card Brands (the “Visa Litigation”). Visa U.S.A. member banks have a contingent obligation to indemnify Visa Inc. under the Visa U.S.A. bylaws (which were modified at the time of the restructuring in October 2007) for potential losses arising from the Visa Litigation. The indemnification by the Visa U.S.A. member banks has no specific maximum amount. Using proceeds from its IPO and through reductions to the conversion ratio applicable to the Class B shares held by Visa U.S.A. member banks, Visa Inc. has funded an escrow account for the benefit of member financial institutions to fund their indemnification obligations associated with the Visa Litigation. The receivable related to the escrow account is classified in other liabilities as a direct offset to the related Visa Litigation contingent liability. In October 2012, Visa signed a settlement agreement to resolve class action claims associated with the multidistrict interchange litigation pending in the United States District Court for the Eastern District of New York (the “Multi-District Litigation”). The U.S. Court of Appeals for the Second Circuit reversed the approval of that settlement and remanded the matter to the district court. Thereafter, the case was split into two putative class actions, one seeking damages (the “Damages Action”) and a separate class action seeking injunctive relief only (the “Injunctive Action”). In September 2018, Visa signed a new settlement agreement, superseding the original settlement agreement, to resolve the Damages Action. The Damages Action settlement was approved by the United States District Court for the Eastern District of New York, but is now on appeal. The Injunctive Action, which generally seeks changes to Visa rules, is still pending. Other Guarantees and Contingent Liabilities The following table is a summary of other guarantees and contingent liabilities of the Company at June 30, 2021: (Dollars in Millions) Collateral Carrying Maximum Standby letters of credit $ – $ 62 $ 9,324 Third party borrowing arrangements – – 3 Securities lending indemnifications 10,080 – 9,818 Asset sales – 86 6,529 (a) Merchant processing 853 207 113,923 Tender option bond program guarantee 1,738 – 1,491 Other – 22 1,628 (a) The maximum potential future payments do not include loan sales where the Company provides standard representation and warranties to the buyer against losses related to loan underwriting documentation defects that may have existed at the time of sale that generally are identified after the occurrence of a triggering event such as delinquency. For these types of loan sales, the maximum potential future payments is generally the unpaid principal balance of loans sold measured at the end of the current reporting period. Actual losses will be significantly less than the maximum exposure, as only a fraction of loans sold will have a representation and warranty breach, and any losses on repurchase would generally be mitigated by any collateral held against the loans. Merchant Processing The Company, through its subsidiaries, provides merchant processing services. Under the rules of credit card associations, a merchant processor retains a contingent liability for credit card transactions processed. This contingent liability arises in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder’s favor. In this situation, the transaction is “charged-back” to the merchant and the disputed amount is credited or otherwise refunded to the cardholder. If the Company is unable to collect this amount from the merchant, it bears the loss for the amount of the refund paid to the cardholder. The Company currently processes card transactions in the United States, Canada and Europe through wholly-owned subsidiaries. In the event a merchant was unable to fulfill product or services subject to future delivery, such as airline tickets, the Company could become financially liable for refunding the purchase price of such products or services purchased through the credit card associations under the charge-back provisions. Charge-back risk related to these merchants is evaluated in a manner similar to credit risk assessments and, as such, merchant processing contracts contain various provisions to protect the Company in the event of default. At June 30, 2021, the value of airline tickets purchased to be delivered at a future date through card transactions processed by the Company was $7.7 billion. The Company held collateral of $638 million in escrow deposits, letters of credit and indemnities from financial institutions, and liens on various assets. In addition to specific collateral or other credit enhancements, the Company maintains a liability for its implied guarantees associated with future delivery. At June 30, 2021, the liability was $185 million primarily related to these airline processing arrangements. Asset Sales The Company regularly sells loans to GSEs as part of its mortgage banking activities. The Company provides customary representations and warranties to GSEs in conjunction with these sales. These representations and warranties generally require the Company to repurchase assets if it is subsequently determined that a loan did not meet specified criteria, such as a documentation deficiency or rescission of mortgage insurance. If the Company is unable to cure or refute a repurchase request, the Company is generally obligated to repurchase the loan or otherwise reimburse the GSE for losses. At June 30, 2021, the Company had reserved $18 million for potential losses from representation and warranty obligations, compared with $19 million at December 31, 2020. The Company’s reserve reflects management’s best estimate of losses for representation and warranty obligations. The Company’s repurchase reserve is modeled at the loan level, taking into consideration the individual credit quality and borrower activity that has transpired since origination. The model applies credit quality and economic risk factors to derive a probability of default and potential repurchase that are based on the Company’s historical loss experience, and estimates loss severity based on expected collateral value. The Company also considers qualitative factors that may result in anticipated losses differing from historical loss trends. As of June 30, 2021 and December 31, 2020, the Company had $15 million and $13 million, respectively, of unresolved representation and warranty claims from GSEs. The Company does not have a significant amount of unresolved claims from investors other than GSEs. Litigation and Regulatory Matters The Company is subject to various litigation and regulatory matters that arise in the ordinary course of its business. The Company establishes reserves for such matters when potential losses become probable and can be reasonably estimated. The Company believes the ultimate resolution of existing legal and regulatory matters will not have a material adverse effect on the financial condition, results of operations or cash flows of the Company. However, in light of the uncertainties inherent in these matters, it is possible that the ultimate resolution of one or more of these matters may have a material adverse effect on the Company’s results from operations for a particular period, and future changes in circumstances or additional information could result in additional accruals or resolution in excess of established accruals, which could adversely affect the Company’s results from operations, potentially materially. Residential Mortgage-Backed Securities Litigation Starting in 2011, the Company and other large financial institutions have been sued in their capacity as trustee for residential mortgage–backed securities trusts. In the lawsuits brought against the Company, the investors allege that the Company’s banking subsidiary, U.S. Bank National Association (“U.S. Bank”), as trustee caused them to incur substantial losses by failing to enforce loan repurchase obligations and failing to abide by appropriate standards of care after events of default allegedly occurred. The plaintiffs in these matters seek monetary damages in unspecified amounts and most also seek equitable relief. Regulatory Matters The Company is continually subject to examinations, inquiries and investigations in areas of heightened regulatory scrutiny, such as compliance, risk management, third-party risk management and consumer protection. For example, the Consumer Financial Protection Bureau (“CFPB”) is investigating certain of the Company’s consumer sales practices, and the Company has responded and continues to respond to the CFPB. The Company is cooperating fully with all pending examinations, inquiries and investigations, any of which could lead to administrative or legal proceedings or settlements. Remedies in these proceedings or settlements may include fines, penalties, restitution or alterations in the Company’s business practices (which may increase the Company’s operating expenses and decrease its revenue). Outlook Due to their complex nature, it can be years before litigation and regulatory matters are resolved. The Company may be unable to develop an estimate or range of loss where matters are in early stages, there are significant factual or legal issues to be resolved, damages are unspecified or uncertain, or there is uncertainty as to a litigation class being certified or the outcome of pending motions, appeals or proceedings. For those litigation and regulatory matters where the Company has information to develop an estimate or range of loss, the Company believes the upper end of the range of reasonably possible losses in aggregate, in excess of any reserves established for matters where a loss is considered probable, will not be material to its financial condition, results of operations or cash flows. The Company’s estimates are subject to significant judgment and uncertainties, and the matters underlying the estimates will change from time to time. Actual results may vary significantly from the current estimates.

Business Segments	Note 16 Business Segments Within the Company, financial performance is measured by major lines of business based on the products and services provided to customers through its distribution channels. These operating segments are components of the Company about which financial information is prepared and is evaluated regularly by management in deciding how to allocate resources and assess performance. The Company has five reportable operating segments: Corporate and Commercial Banking Corporate and Commercial Banking offers lending, equipment finance and small-ticket leasing, depository services, treasury management, capital markets services, international trade services and other financial services to middle market, large corporate, commercial real estate, financial institution, non-profit Consumer and Business Banking Consumer and Business Banking delivers products and services through banking offices, telephone servicing and sales, on-line Wealth Management and Investment Services Wealth Management and Investment Services provides private banking, financial advisory services, investment management, retail brokerage services, insurance, trust, custody and fund servicing through four businesses: Wealth Management, Global Corporate Trust & Custody, U.S. Bancorp Asset Management and Fund Services. Payment Services Payment Services includes consumer and business credit cards, stored-value cards, debit cards, corporate, government and purchasing card services, consumer lines of credit and merchant processing. Treasury and Corporate Support Treasury and Corporate Support includes the Company’s investment portfolios, funding, capital management, interest rate risk management, income taxes not allocated to business segments, including most investments in tax-advantaged Basis of Presentation Business segment results are derived from the Company’s business unit profitability reporting systems by specifically attributing managed balance sheet assets, deposits and other liabilities and their related income or expense. The allowance for credit losses and related provision expense are allocated to the business segments according to the volume and credit quality of the loan balances managed, but with the impact of changes in economic forecasts recorded in Treasury and Corporate Support. Goodwill and other intangible assets are assigned to the business segments based on the mix of business of an entity acquired by the Company. Within the Company, capital levels are evaluated and managed centrally; however, capital is allocated to the business segments to support evaluation of business performance. Business segments are allocated capital on a risk-adjusted basis considering economic and regulatory capital requirements. Generally, the determination of the amount of capital allocated to each business segment includes credit allocations following a Basel III regulatory framework. Interest income and expense is determined based on the assets and liabilities managed by the business segment. Because funding and asset liability management is a central function, funds transfer-pricing methodologies are utilized 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. Also, each business unit is allocated the taxable-equivalent benefit of tax-exempt charge-off. Designations, assignments and allocations change from time to time as management systems are enhanced, methods of evaluating performance or product lines change or business segments are realigned to better respond to the Company’s diverse customer base. During 2021, certain organization and methodology changes were made and, accordingly, 2020 results were restated and presented on a comparable basis.

Loans and Allowance for Credit Losses	Allowance for Credit Losses Beginning January 1, 2020, the allowance for credit losses is established for current expected credit losses on the Company’s loan and lease portfolio, including unfunded credit commitments. The allowance considers expected losses for the remaining lives of the applicable assets, inclusive of expected recoveries. The allowance for credit losses is increased through provisions charged to earnings and reduced by net charge-offs. Management evaluates the appropriateness of the allowance for credit losses on a quarterly basis. Multiple economic scenarios are considered over a three-year reasonable and supportable forecast period, which includes increasing consideration of historical loss experience over years two and three. These economic scenarios are constructed with interrelated projections of multiple economic variables, and loss estimates are produced that consider the historical correlation of those economic variables with credit losses. After the forecast period, the Company fully reverts to long-term historical loss experience, adjusted for prepayments and characteristics of the current loan and lease portfolio, to estimate losses over the remaining life of the portfolio. The economic scenarios are updated at least quarterly and are designed to provide a range of reasonable estimates from better to worse than current expectations. Scenarios are weighted based on the Company’s expectation of economic conditions for the foreseeable future and reflect significant judgment and consideration of uncertainties that exist. Final loss estimates also consider factors affecting credit losses not reflected in the scenarios, due to the unique aspects of current conditions and expectations. These factors may include, but are not limited to, loan servicing practices, regulatory guidance, and/or fiscal and monetary policy actions. The allowance recorded for credit losses utilizes forward-looking expected loss models to consider a variety of factors affecting lifetime credit losses. These factors include, but are not limited to, macroeconomic variables such as unemployment rate, real estate prices, gross domestic product levels and corporate bonds spreads, as well as loan and borrower characteristics, such as internal risk ratings on commercial loans and consumer credit scores, delinquency status, collateral type and available valuation information, consideration of end-of-term charged-off than $ million in the commercial lending segment is based on an analysis utilizing expected cash flows discounted using the original effective interest rate, the observable market price of the loan, or the fair value of the c The allowance recorded for Troubled Debt Restructuring (“TDR”) loans in the consumer lending segment is determined on a homogenous pool basis utilizing expected cash flows discounted using the original effective interest rate of the pool. TDRs generally do not include loan modifications granted to customers resulting directly from the economic effects of the COVID-19 pandemic, who were otherwise in current payment status. The expected cash flows on TDR loans consider subsequent payment defaults since modification, the borrower’s ability to pay under the restructured terms, and the timing and amount of payments. The allowance for collateral-dependent loans in the consumer lending segment is determined based on the fair value of the collateral less costs to sell. With respect to the commercial lending segment, TDRs may be collectively evaluated for impairment where observed performance history, including defaults, is a primary driver of the loss allocation. For commercial TDRs individually evaluated for impairment, attributes of the borrower are the primary factors in determining the allowance for credit losses. However, historical loss experience is also incorporated into the allowance methodology applied to this category of loans. Beginning January 1, 2020, when a loan portfolio is purchased, the acquired loans are divided into those considered purchased with more than insignificant credit deterioration (“PCD”) and those not considered purchased with more than insignificant credit deterioration. An allowance is established for each population and considers product mix, risk characteristics of the portfolio, bankruptcy experience, delinquency status and refreshed LTV ratios when possible. The allowance established for purchased loans not considered PCD is recognized through provision expense upon acquisition, whereas the allowance established for loans considered PCD at acquisition is offset by an increase in the basis of the acquired loans. Any subsequent increases and decreases in the allowance related to purchased loans, regardless of PCD status, are recognized through provision expense, with charge-offs charged to the allowance. The Company did not have a material amount of PCD loans included in its loan portfolio at June 30, 2021. The Company’s methodology for determining the appropriate allowance for credit losses also considers the imprecision inherent in the methodologies used and allocated to the various loan portfolios. As a result, amounts determined under the methodologies described above, are adjusted by management to consider the potential impact of other qualitative factors not captured in the quantitative model adjustments which include, but are not limited to the following: model imprecision, imprecision in economic scenario assumptions, and emerging risks related to either changes in the environment that are affecting specific portfolios, or changes in portfolio concentrations over time that may affect model performance. The consideration of these items results in adjustments to allowance amounts included in the Company’s allowance for credit losses for each loan portfolio. The Company also assesses the credit risk associated with off-balance off-balance Prior to January 1, 2020, the allowance for credit losses was established based on an incurred loss model. The allowance recorded for loans in the commercial lending segment was based on the migration analysis of commercial loans and actual loss experience. The allowance recorded for loans in the consumer lending segment was determined on a homogenous pool basis and primarily included consideration of delinquency status and historical losses. In addition to the amounts determined under the methodologies described above, management also considered the potential impact of qualitative factors. Credit Quality The credit quality of the Company’s loan portfolios is assessed as a function of net credit losses, levels of nonperforming assets and delinquencies, and credit quality ratings as defined by the Company. For all loan portfolio classes, loans are considered past due based on the number of days delinquent except for monthly amortizing loans which are classified delinquent based upon the number of contractually required payments not made (for example, two missed payments is considered 30 days delinquent). When a loan is placed on nonaccrual status, unpaid accrued interest is reversed, reducing interest income in the current period. Commercial lending segment loans are generally placed on nonaccrual status when the collection of principal and interest has become 90 days past due or is otherwise considered doubtful. Commercial lending segment loans are generally fully or partially charged down to the fair value of the collateral securing the loan, less costs to sell, when the loan is placed on nonaccrual. Consumer lending segment loans are generally charged-off 1-4 value of the collateral securing the loan, less costs to sell, at 180 days past due. Residential mortgage loans and lines in a first lien position are placed on nonaccrual status in instances where a partial charge-off 1-4 charged-off. charged-off 1-4 charged-off charged-off charge-off. For all loan classes, interest payments received on nonaccrual loans are generally recorded as a reduction to a loan’s carrying amount while a loan is on nonaccrual and are recognized as interest income upon payoff of the loan. However, interest income may be recognized for interest payments if the remaining carrying amount of the loan is believed to be collectible. In certain circumstances, loans in any class may be restored to accrual status, such as when a loan has demonstrated sustained repayment performance or no amounts are past due and prospects for future payment are no longer in doubt; or when the loan becomes well secured and is in the process of collection. Loans where there has been a partial charge-off charged-off) The Company classifies its loan portfolio classes using internal credit quality ratings on a quarterly basis. These ratings include pass, special mention and classified, and are an important part of the Company’s overall credit risk management process and evaluation of the allowance for credit losses. Loans with a pass rating represent those loans not classified on the Company’s rating scale for problem credits, as minimal credit risk has been identified. Special mention loans are those loans that have a potential weakness deserving management’s close attention. Classified loans are those loans where a well-defined weakness has been identified that may put full collection of contractual cash flows at risk. It is possible that others, given the same information, may reach different reasonable conclusions regarding the credit quality rating classification of specific loans. Troubled Debt Restructurings In certain circumstances, the Company may modify the terms of a loan to maximize the collection of amounts due when a borrower is experiencing financial difficulties or is expected to experience difficulties in the near-term. Concessionary modifications are classified as TDRs unless the modification results in only an insignificant delay in payments to be received. The Company recognizes interest on TDRs if the borrower complies with the revised terms and conditions as agreed upon with the Company and has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles, which is generally six months or greater. To the extent a previous restructuring was insignificant, the Company considers the cumulative effect of past restructurings related to the receivable when determining whether a current restructuring is a TDR. The Company has implemented certain restructuring programs that may result in TDRs. However, many of the Company’s TDRs are also determined on a case-by-case For the commercial lending segment, modifications generally result in the Company working with borrowers on a case-by-case Modifications for the consumer lending segment are generally part of programs the Company has initiated. The Company modifies residential mortgage loans under Federal Housing Administration, United States Department of Veterans Affairs, or its own internal programs. Under these programs, the Company offers qualifying homeowners the opportunity to permanently modify their loan and achieve more affordable monthly payments by providing loan concessions. These concessions may include adjustments to interest rates, conversion of adjustable rates to fixed rates, extension of maturity dates or deferrals of payments, capitalization of accrued interest and/or outstanding advances, or in limited situations, partial forgiveness of loan principal. In most instances, participation in residential mortgage loan restructuring programs requires the customer to complete a short-term trial period. A permanent loan modification is contingent on the customer successfully completing the trial period arrangement, and the loan documents are not modified until that time. The Company reports loans in a trial period arrangement as TDRs and continues to report them as TDRs after the trial period. Credit card and other retail loan TDRs are generally part of distinct restructuring programs providing customers experiencing financial difficulty with modifications whereby balances may be amortized up to 60 months, and generally include waiver of fees and reduced interest rates. In addition, the Company considers secured loans to consumer borrowers that have debt discharged through bankruptcy where the borrower has not reaffirmed the debt to be TDRs.
Accounting for Transfers and Servicing of Financial Assets	In accordance with the accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets can be derecognized from the balance sheet.For loans sold under participation agreements, the Company also considers whether the terms of the loan participation agreement meet the accounting definition of a participating interest. With the exception of servicing and certain performance-based guarantees, the Company’s continuing involvement with financial assets sold is minimal and generally limited to market customary representation and warranty clauses. Any gain or loss on sale depends on the previous carrying amount of the transferred financial assets, the consideration received, and any liabilities incurred in exchange for the transferred assets. Upon transfer, any servicing assets and other interests that continue to be held by the Company are initially recognized at fair value.
Variable Interest Entities	The Company is not required to consolidate VIEs in which it has concluded it does not have a controlling financial interest, and thus is not the primary beneficiary. In such cases, the Company does not have both the power to direct the entities’ most significant activities and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIEs. The Company’s investments in these unconsolidated VIEs are carried in other assets on the Consolidated Balance Sheet. The Company’s unfunded capital and other commitments related to these unconsolidated VIEs are generally carried in other liabilities on the Consolidated Balance Sheet. The Company’s maximum exposure to loss from these unconsolidated VIEs include the investment recorded on the Company’s Consolidated Balance Sheet, net of unfunded capital commitments, and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. While the Company believes potential losses from these investments are remote, the maximum exposure was determined by assuming a scenario where the community-based business and housing projects completely fail and do not meet certain government compliance requirements resulting in recapture of the related tax credits. The following table provides a summary of investments in community development and tax-advantaged tax-advantaged
Netting Arrangements for Certain Financial Instruments	The Company’s derivative contracts typically include offsetting rights (referred to as netting arrangements), and depending on expected volume, credit risk, and counterparty preference, collateral maintenance may be required. For all derivatives under collateral support arrangements, fair value is determined daily and, depending on the collateral maintenance requirements, the Company and a counterparty may receive or deliver collateral, based upon the net fair value of all derivative positions between the Company and the counterparty. Collateral is typically cash, but securities may be allowed under collateral arrangements with certain counterparties. Receivables and payables related to cash collateral are included in other assets and other liabilities on the Consolidated Balance Sheet, along with the related derivative asset and liability fair values. Any securities pledged to counterparties as collateral remain on the Consolidated Balance Sheet. Securities received from counterparties as collateral are not recognized on the Consolidated Balance Sheet, unless the counterparty defaults. In general, securities used as collateral can be sold, repledged or otherwise used by the party in possession. No restrictions exist on the use of cash collateral by either party. Refer to Note 12 for further discussion of the Company’s derivatives, including collateral arrangements. As part of the Company’s treasury and broker-dealer operations, the Company executes transactions that are treated as securities sold under agreements to repurchase or securities purchased under agreements to resell, both of which are accounted for as collateralized financings. Securities sold under agreements to repurchase include repurchase agreements and securities loaned transactions. Securities purchased under agreements to resell include reverse repurchase agreements and securities borrowed transactions. For securities sold under agreements to repurchase, the Company records a liability for the cash received, which is included in short-term borrowings on the Consolidated Balance Sheet. For securities purchased under agreements to resell, the Company records a receivable for the cash paid, which is included in other assets on the Consolidated Balance Sheet. Securities transferred to counterparties under repurchase agreements and securities loaned transactions continue to be recognized on the Consolidated Balance Sheet, are measured at fair value, and are included in investment securities or other assets. Securities received from counterparties under reverse repurchase agreements and securities borrowed transactions are not recognized on the Consolidated Balance Sheet unless the counterparty defaults. The securities transferred under repurchase and reverse repurchase transactions typically are U.S. Treasury and agency securities, residential agency mortgage-backed securities or corporate debt securities. The securities loaned or borrowed typically are corporate debt securities traded by the Company’s broker-dealer subsidiary. In general, the securities transferred can be sold, repledged or otherwise used by the party in possession. No restrictions exist on the use of cash collateral by either party. Repurchase/reverse repurchase and securities loaned/borrowed transactions expose the Company to counterparty risk. The Company manages this risk by performing assessments, independent of business line managers, and establishing concentration limits on each counterparty. Additionally, these transactions include collateral arrangements that require the fair values of the underlying securities to be determined daily, resulting in cash being obtained or refunded to counterparties to maintain specified collateral levels. The Company executes its derivative, repurchase/reverse repurchase and securities loaned/borrowed transactions under the respective industry standard agreements. These agreements include master netting arrangements that allow for multiple contracts executed with the same counterparty to be viewed as a single arrangement. This allows for net settlement of a single amount on a daily basis. In the event of default, the master netting arrangement provides for close-out The Company has elected to offset the assets and liabilities under netting arrangements for the balance sheet presentation of the majority of its derivative counterparties. The netting occurs at the counterparty level, and includes all assets and liabilities related to the derivative contracts, including those associated with cash collateral received or delivered. The Company has not elected to offset the assets and liabilities under netting arrangements for the balance sheet presentation of repurchase/reverse repurchase and securities loaned/borrowed transactions.
Fair Values of Assets and Liabilities	The Company uses fair value measurements for the initial recording of certain assets and liabilities, periodic remeasurement of certain assets and liabilities, and disclosures. Derivatives, trading and available-for-sale lower-of-cost-or-fair Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. The Company groups its assets and liabilities measured at fair value into a three-level hierarchy for valuation techniques used to measure financial assets and financial liabilities at fair value. This hierarchy is based on whether the valuation inputs are observable or unobservable. These levels are: • Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 1 includes U.S. Treasury securities, as well as exchange-traded instruments. • Level 2 — Observable 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 2 includes debt securities that are traded less frequently than exchange-traded instruments and which are typically valued using third party pricing services; derivative contracts and other assets and liabilities, including securities, whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data; and MLHFS whose values are determined using quoted prices for similar assets or pricing models with inputs that are observable in the market or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. This category includes MSRs and certain derivative contracts.

Summary of Other Guarantees and Contingent Liabilities	The following table is a summary of other guarantees and contingent liabilities of the Company at June 30, 2021: (Dollars in Millions) Collateral Carrying Maximum Standby letters of credit $ – $ 62 $ 9,324 Third party borrowing arrangements – – 3 Securities lending indemnifications 10,080 – 9,818 Asset sales – 86 6,529 (a) Merchant processing 853 207 113,923 Tender option bond program guarantee 1,738 – 1,491 Other – 22 1,628 (a) The maximum potential future payments do not include loan sales where the Company provides standard representation and warranties to the buyer against losses related to loan underwriting documentation defects that may have existed at the time of sale that generally are identified after the occurrence of a triggering event such as delinquency. For these types of loan sales, the maximum potential future payments is generally the unpaid principal balance of loans sold measured at the end of the current reporting period. Actual losses will be significantly less than the maximum exposure, as only a fraction of loans sold will have a representation and warranty breach, and any losses on repurchase would generally be mitigated by any collateral held against the loans.
