Accounting Changes and Error Corrections [Abstract]
Accounting Changes	Note 2 Accounting Changes Financial Instruments—Credit Losses Effective January 1, 2020, the Company adopted accounting guidance, issued by the Financial Accounting Standards Board (“FASB”) in June 2016, related to the impairment of financial instruments. This guidance changes impairment recognition to a model that is based on expected losses rather than incurred losses, which is intended to result in more timely recognition of credit losses. This guidance is also intended to reduce the complexity of accounting guidance by decreasing the number of credit impairment models that entities use to account for debt instruments. In addition, the guidance requires additional credit quality disclosures for loans. Upon adoption, the Company increased its allowance for credit losses by approximately $1.5 billion and reduced retained earnings net of deferred tax balances by approximately $1.1 billion through a cumulative-effect adjustment. The Company has elected to defer the impact of the effect of the guidance at adoption plus 25 percent of its quarterly credit reserve increases over the next two years on its regulatory capital requirements, followed by a transition period to phase in the cumulative deferred impact at 25 percent per year from 2022 to 2025, as provided by rules issued by its regulators. When determining expected losses, the Company uses multiple economic scenarios and a three-year reasonable and supportable forecast period, which incorporates historical loss experience in years two and three. 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 lives of the financial instruments. The increase in the allowance at adoption was primarily related to the commercial, credit card, installment and other retail loan portfolios where the allowance for loan losses had not previously considered the full term of the loans. The Company also recognized an additional $1.3 billion and $1.9 billion increase in its allowance for credit losses during the second quarter and first six months of 2020, respectively, utilizing this guidance. These increases reflected deteriorating economic conditions driven by the impact of COVID-19 The adoption of this guidance did not have a material impact on the Company’s available-for-sale 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 have 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 currently assessing the impact of this guidance on its financial statements.

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, 2020, 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 $922 million at June 30, 2020 and $781 million at December 31, 2019. 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 (“PCD”) loans. All other purchased loans are considered non-purchased The Company offers a broad array of lending products and categorizes its loan portfolio into two segments, which is the level at which it develops and documents a systematic methodology to determine the allowance for credit losses. The Company’s two loan portfolio segments are commercial lending and consumer lending. Allowance for Credit Losses Effective 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. Prior to January 1, 2020, the allowance for credit losses was established based on an incurred loss model. 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. The allowance considers expected losses for the remaining lives of the applicable assets, inclusive of expected recoveries. Multiple economic scenarios are considered over a three-year reasonable and supportable forecast period, which incorporates historical loss experience in years two and three. 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 lives. The economic scenarios are updated at least quarterly and are designed to provide a range of reasonable estimates, both better and worse than current expectations. Scenarios are weighted based on the Company’s expectation of future conditions. 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 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 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, 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 do not include loan modifications granted to customers resulting directly from the economic effects of the COVID-19 Beginning January 1, 2020, when a loan portfolio is purchased, an allowance is established for those loans considered purchased with more-than-insignificant credit deterioration, or PCD loans, and those not considered purchased with more-than-insignificant credit deterioration. The allowance established for each population considers product mix, risk characteristics of the portfolio, bankruptcy experience, delinquency status, refreshed loan-to-value The Company’s methodology for determining the appropriate allowance for credit losses for each loan segment also considers the imprecision inherent in the methodologies used. As a result, amounts determined under the methodologies described above are adjusted by management to consider the potential impact of other qualitative factors 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 portfolio segments, 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 specific to each portfolio class. The Company also assesses the credit risk associated with off-balance off-balance 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 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 loans charged-off 111 22 (3 ) 229 78 437 Balance at end of period $ 2,645 $ 1,269 $ 633 $ 2,156 $ 1,187 $ 7,890 2019 Balance at beginning of period $ 1,445 $ 812 $ 445 $ 1,115 $ 634 $ 4,451 Add Provision for credit losses 78 (17 ) (3 ) 244 63 365 Deduct Loans charged-off 98 3 11 262 90 464 Less recoveries of loans charged-off (39 ) (2 ) (7 ) (35 ) (31 ) (114 ) Net loans charged-off 59 1 4 227 59 350 Balance at end of period $ 1,464 $ 794 $ 438 $ 1,132 $ 638 $ 4,466 Six Months Ended June 30 (Dollars in Millions) Commercial Commercial Residential Credit Other Total 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 loans charged-off 185 20 (2 ) 463 164 830 Balance at end of period $ 2,645 $ 1,269 $ 633 $ 2,156 $ 1,187 $ 7,890 2019 Balance at beginning of period $ 1,454 $ 800 $ 455 $ 1,102 $ 630 $ 4,441 Add Provision for credit losses 142 (5 ) (10 ) 482 133 742 Deduct Loans charged-off 209 4 19 519 186 937 Less recoveries of loans charged-off (77 ) (3 ) (12 ) (67 ) (61 ) (220 ) Net loans charged-off 132 1 7 452 125 717 Balance at end of period $ 1,464 $ 794 $ 438 $ 1,132 $ 638 $ 4,466 (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 increase in the allowance for credit losses from December 31, 2019 to June 30, 2020 reflected the adoption of new accounting guidance and deteriorating economic conditions driven by the impact of COVID-19 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 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 charge-off 1-4 family 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, 2020 Commercial $ 119,316 $ 399 $ 90 $ 456 $ 120,261 Commercial real estate 40,776 103 2 195 41,076 Residential mortgages (a) 70,731 241 115 242 71,329 Credit card 20,768 230 259 – 21,257 Other retail 55,890 254 90 178 56,412 Total loans $ 307,481 $ 1,227 $ 556 $ 1,071 $ 310,335 December 31, 2019 Commercial $ 103,273 $ 307 $ 79 $ 204 $ 103,863 Commercial real estate 39,627 34 3 82 39,746 Residential mortgages (a) 70,071 154 120 241 70,586 Credit card 24,162 321 306 – 24,789 Other retail 56,463 393 97 165 57,118 Total loans $ 293,596 $ 1,209 $ 605 $ 692 $ 296,102 (a) At June 30, 2020, $656 million 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 $428 million and $1.7 billion at December 31, 2019, respectively.

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 The following table provides a summary of loans modified as TDRs during the periods presented by portfolio class: 2020 2019 (Dollars in Millions) Number Pre-Modification Post-Modification Number Pre-Modification Post-Modification Three Months Ended June 30 Commercial 1,139 $ 144 $ 115 823 $ 90 $ 86 Commercial real estate 38 39 39 24 25 24 Residential mortgages 121 24 24 105 12 13 Credit card 6,168 37 38 7,941 44 44 Other retail 374 9 8 642 13 13 Total loans, excluding loans purchased from GNMA mortgage pools 7,840 253 224 9,535 184 180 Loans purchased from GNMA mortgage pools 1,009 142 138 1,555 215 208 Total loans 8,849 $ 395 $ 362 11,090 $ 399 $ 388 Six Months Ended June 30 Commercial 2,138 $ 243 $ 216 1,736 $ 126 $ 115 Commercial real estate 65 60 60 44 72 70 Residential mortgages 211 34 34 201 26 26 Credit card 14,583 83 85 17,589 94 95 Other retail 1,029 24 22 1,215 24 23 Total loans, excluding loans purchased from GNMA mortgage pools 18,026 444 417 20,785 342 329 Loans purchased from GNMA mortgage pools 2,913 408 398 3,093 418 403 Total loans 20,939 $ 852 $ 815 23,878 $ 760 $ 732 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. 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 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 not considered to be 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 . 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 sheet. 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 $13 million and $7 million of support to the funds during the three months ended June 30, 2020 and 2019, respectively, and $21 million and $14 million during the six months ended June 30, 2020 and 2019, 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, 2020 December 31, 2019 Investment carrying amount $ 6,345 $ 6,148 Unfunded capital and other commitments 2,966 2,938 Maximum exposure to loss 12,204 12,118 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 $34 million at June 30, 2020 and $31 million at December 31, 2019. The maximum exposure to loss related to these VIEs was $55 million at June 30, 2020 and December 31, 2019, 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 $84 million at June 30, 2020, compared with less than $1 million to $87 million at December 31, 2019. 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 investments to third parties. tax-advantaged The majority of the assets of these consolidated VIEs are reported in other assets, and the liabilities are reported in long-term debt and other liabilities. The assets of a particular VIE are the primary source of funds to settle its obligations. The creditors of the VIEs do not have recourse to the general credit of the Company. The Company’s exposure to the consolidated VIEs is generally limited to the carrying value of its variable interests plus any related tax credits previously recognized or transferred to others with a guarantee. 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, 2020, $3.0 billion of available-for-sale available-for-sale

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 $220.3 billion of residential mortgage loans for others at June 30, 2020, and $226.0 billion at December 31, 2019, 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 net gains of $24 million and net losses of $14 million for the three months ended June 30, 2020 and 2019, respectively, and net gains of $49 million and net losses of $3 million for the six months ended June 30, 2020 and 2019, respectively. Loan servicing and ancillary fees, not including valuation changes, included in mortgage banking revenue were $174 million and $180 million for the three months ended June 30, 2020 and 2019, respectively, and $360 million and $359 million for the six months ended June 30, 2020 and 2019, respectively.

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 fixed-rate debt. Changes in the fair value of derivatives designated as fair value hedges, and changes in the fair value of the hedged items, are recorded in earnings. 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, 2020, the Company had $240 million (net-of-tax) (net-of-tax) (net-of-tax) (net-of-tax), 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. The Company’s collateral arrangements are predominately bilateral and, therefore, contain provisions that require collateralization of the Company’s net liability derivative positions. Required collateral coverage is based on net liability thresholds and may be contingent upon the Company’s credit rating from two of the nationally recognized statistical rating organizations. If the Company’s credit rating were to fall below credit ratings thresholds established in the collateral arrangements, the counterparties to the derivatives could request immediate additional collateral coverage up to and including full collateral coverage for derivatives in a net liability position. The aggregate fair value of all derivatives under collateral arrangements that were in a net liability position at June 30, 2020, was $1.4 billion. At June 30, 2020, the Company had $1.1 billion of cash posted as collateral against this net liability position.

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, 2020 Repurchase agreements U.S. Treasury and agencies $ 236 $ – $ – $ – $ 236 Residential agency mortgage-backed securities 741 265 – – 1,006 Corporate debt securities 628 – – – 628 Total repurchase agreements 1,605 265 – – 1,870 Securities loaned Corporate debt securities 321 – – – 321 Total securities loaned 321 – – – 321 Gross amount of recognized liabilities $ 1,926 $ 265 $ – $ – $ 2,191 December 31, 2019 Repurchase agreements U.S. Treasury and agencies $ 289 $ – $ – $ – $ 289 Residential agency mortgage-backed securities 266 – – – 266 Corporate debt securities 610 – – – 610 Total repurchase agreements 1,165 – – – 1,165 Securities loaned Corporate debt securities 50 – – – 50 Total securities loaned 50 – – – 50 Gross amount of recognized liabilities $ 1,215 $ – $ – $ – $ 1,215 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 Liabi

Fair Values of Assets and Liabilities	6 Months Ended

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, 2020 and 2019, 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 was a net gain of $81 million and $25 million for the three months ended June 30, 2020 and 2019, respectively, and a net gain of $174 million and $43 million for the six months ended June 30, 2020 and 2019, 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, 2020: Minimum Maximum Weighted Expected prepayment 15 % 25 % 20 % Option adjusted spread 5 7 6 (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, 2020: Minimum Maximum Weighted Expected loan close rate 10 % 100 % 75 % Inherent MSR value (basis points per loan) 36 171 106 (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, 2020, 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, 90 percent and 2 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, 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 Brand 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 brand 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 multi-district 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 (“Damages Action”) and a separate class action seeking injunctive relief only (“Injuctive 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, 2020: (Dollars in Millions) Collateral Carrying Maximum Potential Future Standby letters of credit $ – $ 67 $ 9,877 Third party borrowing arrangements – – 3 Securities lending indemnifications 4,995 – 4,917 Asset sales – 76 4,990 (a) Merchant processing 864 171 72,705 Tender option bond program guarantee 2,968 – 2,618 Other – 86 1,393 (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 and a network of other financial institutions. 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, 2020, the value of airline tickets purchased to be delivered at a future date through card transactions processed by the Company was $9.5 billion. The Company held collateral of $743 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, 2020, the liability was $144 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, 2020, the Company had reserved $19 million for potential losses from representation and warranty obligations, compared with $9 million at December 31, 2019. 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, 2020 and December 31, 2019, the Company had $11 million and $10 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. 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 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. directly support another business segment’s operations are charged to the applicable business segment based on its utilization of those services, primarily measured by the volume of customer activities, number of employees or other relevant factors. These allocated expenses are reported as net shared services expense within noninterest expense. Certain activities that do not directly support the operations of the business segments or for which the business segments are not considered financially accountable in evaluating their performance are not charged to the business segments. The income or expenses associated with these corporate activities is reported within the Treasury and Corporate Support business segment. Income taxes are assessed to each business segment at a standard tax rate with the residual tax expense or benefit to arrive at the consolidated effective tax rate included in Treasury and Corporate Support. 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 2020, certain organization and methodology changes were made and, accordingly, 2019 results were restated and presented on a comparable basis.

Accounting Policies [Abstract]
Basis of Presentation	The accompanying consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q Form 10-K
Accounting Changes	Financial Instruments—Credit Losses Effective January 1, 2020, the Company adopted accounting guidance, issued by the Financial Accounting Standards Board (“FASB”) in June 2016, related to the impairment of financial instruments. This guidance changes impairment recognition to a model that is based on expected losses rather than incurred losses, which is intended to result in more timely recognition of credit losses. This guidance is also intended to reduce the complexity of accounting guidance by decreasing the number of credit impairment models that entities use to account for debt instruments. In addition, the guidance requires additional credit quality disclosures for loans. Upon adoption, the Company increased its allowance for credit losses by approximately $1.5 billion and reduced retained earnings net of deferred tax balances by approximately $1.1 billion through a cumulative-effect adjustment. The Company has elected to defer the impact of the effect of the guidance at adoption plus 25 percent of its quarterly credit reserve increases over the next two years on its regulatory capital requirements, followed by a transition period to phase in the cumulative deferred impact at 25 percent per year from 2022 to 2025, as provided by rules issued by its regulators. When determining expected losses, the Company uses multiple economic scenarios and a three-year reasonable and supportable forecast period, which incorporates historical loss experience in years two and three. 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 lives of the financial instruments. The increase in the allowance at adoption was primarily related to the commercial, credit card, installment and other retail loan portfolios where the allowance for loan losses had not previously considered the full term of the loans. The Company also recognized an additional $1.3 billion and $1.9 billion increase in its allowance for credit losses during the second quarter and first six months of 2020, respectively, utilizing this guidance. These increases reflected deteriorating economic conditions driven by the impact of COVID-19 The adoption of this guidance did not have a material impact on the Company’s available-for-sale 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 have 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 currently assessing the impact of this guidance on its financial statements.
Loans and Allowance for Credit Losses	Allowance for Credit Losses Effective 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. Prior to January 1, 2020, the allowance for credit losses was established based on an incurred loss model. 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. The allowance considers expected losses for the remaining lives of the applicable assets, inclusive of expected recoveries. Multiple economic scenarios are considered over a three-year reasonable and supportable forecast period, which incorporates historical loss experience in years two and three. 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 lives. The economic scenarios are updated at least quarterly and are designed to provide a range of reasonable estimates, both better and worse than current expectations. Scenarios are weighted based on the Company’s expectation of future conditions. 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 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 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, 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 do not include loan modifications granted to customers resulting directly from the economic effects of the COVID-19 Beginning January 1, 2020, when a loan portfolio is purchased, an allowance is established for those loans considered purchased with more-than-insignificant credit deterioration, or PCD loans, and those not considered purchased with more-than-insignificant credit deterioration. The allowance established for each population considers product mix, risk characteristics of the portfolio, bankruptcy experience, delinquency status, refreshed loan-to-value The Company’s methodology for determining the appropriate allowance for credit losses for each loan segment also considers the imprecision inherent in the methodologies used. As a result, amounts determined under the methodologies described above are adjusted by management to consider the potential impact of other qualitative factors 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 portfolio segments, 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 specific to each portfolio class. The Company also assesses the credit risk associated with off-balance off-balance The increase in the allowance for credit losses from December 31, 2019 to June 30, 2020 reflected the adoption of new accounting guidance and deteriorating economic conditions driven by the impact of COVID-19 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 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 charge-off 1-4 family 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 portfolios using internal credit quality ratings on a quarterly basis. These 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 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. 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 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 not considered 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 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 investments to third parties. The majority of the assets of these consolidated VIEs are reported in other assets, and the liabilities are reported in long-term debt and other liabilities. The assets of a particular VIE are the primary source of funds to settle its obligations. The creditors of the VIEs do not have recourse to the general credit of the Company. The Company’s exposure to the consolidated VIEs is generally limited to the carrying value of its variable interests plus any related tax credits previously recognized or transferred to others with a guarantee.
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. 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, 2020: (Dollars in Millions) Collateral Carrying Maximum Potential Future Standby letters of credit $ – $ 67 $ 9,877 Third party borrowing arrangements – – 3 Securities lending indemnifications 4,995 – 4,917 Asset sales – 76 4,990 (a) Merchant processing 864 171 72,705 Tender option bond program guarantee 2,968 – 2,618 Other – 86 1,393 (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.
