Basis of Presentation	Note 1 Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q Form 10-K Accounting policies for the lines of business are generally the same as those used in preparation of the consolidated financial statements with respect to activities specifically attributable to each business line. However, the preparation of business line results requires management to establish methodologies to allocate funding costs, expenses and other financial elements to each line of business. Table 11 “Line of Business Financial Performance” included in Management’s Discussion and Analysis provides details of segment results. This information is incorporated by reference into these Notes to Consolidated Financial Statements.

Accounting Changes and Error Corrections [Abstract]
Accounting Changes	Note 2 Accounting Changes Accounting for Leases Effective January 1, 2019, the Company adopted accounting guidance, issued by the Financial Accounting Standards Board (“FASB”) in February 2016, related to the accounting for leases. This guidance requires lessees to recognize all leases on the Consolidated Balance Sheet as lease assets and lease liabilities based primarily on the present value of future lease payments. The Company recognized approximately $1.3 billion of lease assets and related liabilities on its Consolidated Balance Sheet at the adoption date. In addition, lessors are now required to consider lease residual exposures of sales-type and direct financing leases when determining the allowance for credit losses. The adoption of this guidance was not material to the Company’s Consolidated Statement of Income. Financial Instruments — Credit Losses In June 2016, the FASB issued accounting guidance, related to the impairment of financial instruments which the Company will adopt effective January 1, 2020. This guidance changes existing 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 current accounting guidance by decreasing the n The extent of the impact of this guidance will depend on economic conditions and the composition of the Company’s loan portfolio at the adoption date, as well as further refinements to the Company’s process, judgements and models to quantify credit impairment under the new standard. The Company expects the new standard to increase its allowance for credit losses by $ 1.2 When determining expected losses, the Company uses multiple economic scenarios and a three-year reasonable and supportable forecast period. After the forecast period, the Company reverts to long-term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life. The estimated increase in the allowance is primarily related to the credit card, installment and other retail loan portfolios where the existing allowance for loan losses has been based primarily shorter loss period The Company does not expect its held-to-maturity available-for-sale

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 $272 million at September 30, 2019, and $2.1 billion at December 31, 2018.

The Company determines other-than-temporary impairment recorded in earnings for investment securities not intended to be sold by estimating the future cash flows of each individual investment security, using market information where available, and discounting the cash flows at the original effective rate of the investment security. Other-than-temporary impairment recorded in other comprehensive income (loss) is measured as the difference between that discounted amount and the fair value of each investment security. The total amount of other-than-temporary impairment recorded was immaterial for the three and nine months ended September 30, 2019 and 2018.

These unrealized losses primarily relate to changes in interest rates and market spreads subsequent to purchase. A substantial portion of investment securities that have unrealized losses are either U.S. Treasury and agencies, agency mortgage-backed or state and political securities. 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 September 30, 2019, 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 $785 million at September 30, 2019 and $872 million at December 31, 2018. All purchased loans are recorded at fair value at the date of purchase. The Company evaluates purchased loans for impairment at the date of purchase in accordance with applicable authoritative accounting guidance. Purchased loans with evidence of credit deterioration since origination for which it is probable that all contractually required payments will not be collected are considered “purchased impaired loans.” All other purchased loans are considered “purchased nonimpaired loans.” 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. Previously, the Company categorized loans covered under loss sharing or similar credit protection agreements with the Federal Deposit Insurance Corporation (“FDIC”), along with the related indemnification asset, in a separate covered loans segment. During 2018 the majority of these loans were sold and the loss share coverage expired. Any remaining balances were reclassified to be included in their respective portfolio category. Allowance for Credit Losses The allowance for credit losses is established for probable and estimable losses incurred in the Company’s loan and lease portfolio, including unfunded credit commitments. 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 incurred losses on a quarterly basis. The allowance recorded for loans in the commercial lending segment is based on reviews of individual credit relationships and considers the migration analysis of commercial lending segment loans and actual loss experience. For each loan type, this historical loss experience is adjusted as necessary to consider any relevant changes in portfolio composition, lending policies, underwriting standards, risk management practices or economic conditions. The results of the analysis are evaluated quarterly to confirm the selected loss experience is appropriate for each commercial loan type. The allowance recorded for impaired loans greater than $5 million in the commercial lending segment is based on an individual loan 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 collateral, less selling costs, for collateral-dependent loans, rather than the migration analysis. The allowance recorded for all other commercial lending segment loans is determined on a homogenous pool basis and includes consideration of product mix, risk characteristics of the portfolio, delinquency status, bankruptcy experience, portfolio growth and historical losses, adjusted for current trends. The Company also considers the impacts of any loan modifications made to commercial lending segment loans and any subsequent payment defaults to its expectations of cash flows, principal balance, and current expectations about the borrower’s ability to pay in determining the allowance for credit losses. The allowance recorded for Troubled Debt Restructuring (“TDR”) loans and purchased impaired 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, or the prior quarter effective rate, respectively. 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. The allowance recorded for all other consumer lending segment loans is determined on a homogenous pool basis and includes consideration of product mix, risk characteristics of the portfolio, bankruptcy experience, delinquency status, refreshed loan-to-value In addition, subsequent payment defaults on loan modifications considered TDRs are considered in the underlying factors used in the determination of the appropriateness of the allowance for credit losses. For each loan segment, the Company estimates future loan charge-offs through a variety of analysis, trends and underlying assumptions. 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. With respect to the consumer lending segment, performance of the portfolio, including defaults on TDRs, is considered when estimating future cash flows. 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, in addition to the amounts determined under the methodologies described above, management also considers the potential impact of other qualitative factors which include, but are not limited to, economic factors; geographic and other concentration risks; delinquency and nonaccrual trends; current business conditions; changes in lending policy, underwriting standards and other relevant business practices; results of internal review; and the regulatory environment. The consideration of these items results in adjustments to allowance amounts included in the Company’s allowance for credit losses for each of the above loan segments.

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 Total September 30, 2019 Commercial $ 103,782 $ 450 $ 103 $ 319 $ 104,654 Commercial real estate 39,126 51 2 89 39,268 Residential mortgages (a) 68,845 167 115 251 69,378 Credit card 23,296 316 278 — 23,890 Other retail 56,785 391 102 170 57,448 Total loans $ 291,834 $ 1,375 $ 600 $ 829 $ 294,638 December 31, 2018 Commercial $ 101,844 $ 322 $ 69 $ 209 $ 102,444 Commercial real estate 39,354 70 — 115 39,539 Residential mortgages (a) 64,443 181 114 296 65,034 Credit card 22,746 324 293 — 23,363 Other retail 55,722 403 108 197 56,430 Total loans $ 284,109 $ 1,300 $ 584 $ 817 $ 286,810 (a) At September 30, 2019, $391 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 $430 million and $1.7 billion at December 31, 2018, respectively. At September 30, 2019, the amount of foreclosed residential real estate held by the Company, and included in other real estate owned (“OREO”), was $80 million, compared with $106 million at December 31, 2018. These amounts exclude $ $1.2 billion 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 portfolios 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.

For all loan classes, a loan is considered to be impaired when, based on current events or information, it is probable the Company will be unable to collect all amounts due per the contractual terms of the loan agreement. Impaired loans include all nonaccrual and TDR loans. For all loan classes, interest income on TDR loans is recognized under the modified terms and conditions if the borrower has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles. Interest income is generally not recognized on other impaired loans until the loan is paid off. However, interest income may be recognized for interest payments if the remaining carrying amount of the loan is believed to be collectible. Factors used by the Company in determining whether all principal and interest payments due on commercial and commercial real estate loans will be collected and, therefore, whether those loans are impaired include, but are not limited to, the financial condition of the borrower, collateral and/or guarantees on the loan, and the borrower’s estimated future ability to pay based on industry, geographic location and certain financial ratios. The evaluation of impairment on residential mortgages, credit card loans and other retail loans is primarily driven by delinquency status of individual loans or whether a loan has been modified, and considers any government guarantee where applicable. A summary of impaired loans, which include all nonaccrual and TDR loans, by portfolio class was as follows: (Dollars in Millions) Period-end Unpaid Valuation Commitments September 30, 2019 Commercial $ 583 $ 1,183 $ 41 $ 197 Commercial real estate 234 587 8 – Residential mortgages 1,573 1,891 74 – Credit card 262 262 80 – Other retail 322 412 14 2 Total loans, excluding loans purchased from GNMA mortgage pools 2,974 4,335 217 199 Loans purchased from GNMA mortgage pools 1,690 1,690 34 – Total $ 4,664 $ 6,025 $ 251 $ 199 December 31, 2018 Commercial $ 467 $ 1,006 $ 32 $ 106 Commercial real estate 279 511 12 2 Residential mortgages 1,709 1,879 86 – Credit card 245 245 69 – Other retail 335 418 14 5 Total loans, excluding loans purchased from GNMA mortgage pools 3,035 4,059 213 113 Loans purchased from GNMA mortgage pools 1,639 1,639 41 – Total $ 4,674 $ 5,698 $ 254 $ 113 (a) Substantially all loans classified as impaired at September 30, 2019 and December 31, 2018, had an associated allowance for credit losses.

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. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes. The following table provides a summary of loans modified as TDRs during the periods presented by portfolio class: 2019 2018 (Dollars in Millions) Number Pre-Modification Post-Modification Number Pre-Modification Post-Modification Three Months Ended September 30 Commercial 886 $ 116 $ 100 700 $ 42 $ 33 Commercial real estate 32 23 23 38 123 125 Residential mortgages 117 17 15 144 19 17 Credit card 8,429 46 46 8,450 42 43 Other retail 814 20 19 763 17 16 Covered Loans – – – 3 1 1 Total loans, excluding loans purchased from GNMA mortgage pools 10,278 222 203 10,098 244 235 Loans purchased from GNMA mortgage pools 1,524 211 203 1,649 216 211 Total loans 11,802 $ 433 $ 406 11,747 $ 460 $ 446 Nine Months Ended September 30 Commercial 2,622 $ 242 $ 215 2,047 $ 255 $ 234 Commercial real estate 76 95 93 97 154 155 Residential mortgages 318 43 41 397 56 53 Credit card 26,018 140 141 24,457 122 124 Other retail 2,029 44 42 1,857 45 43 Covered Loans – – – 3 1 1 Total loans, excluding loans purchased from GNMA mortgage pools 31,063 564 532 28,858 633 610 Loans purchased from GNMA mortgage pools 4,617 629 606 4,785 631 619 Total loans 35,680 $ 1,193 $ 1,138 33,643 $ 1,264 $ 1,229 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. For those loans modified as TDRs during the third quarter of 2019, at September 30, 2019, 68 residential mortgages, 34 home equity and second mortgage loans and 1,046 loans purchased from GNMA mortgage pools with outstanding balances of $11 million, $3 million and $144 million, respectively, were in a trial period and have estimated post-modification balances of $10 million, $3 million and $141 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. Acquired loans restructured after acquisition are not considered TDRs for accounting and disclosure purposes if the loans evidenced credit deterioration as of the acquisition date and are accounted for in pools.

These loans had aggregate outstanding balances of $25 million and $81 million for the three months and nine months ended September 30, 2019, respectively.

Leases	Note 5 The Company, as a lessor, originates retail and co m relating to At lease inception, retail lease customers are provided with an end-of-term Residual values on leased assets are reviewed regularly for impairment. Residual valuations for retail leases are based on independent assessments of expected used automobile sale prices at the end of the lease term. Impairment tests are conducted based on these valuations considering the probability of the lessee returning the asset to the Company, re-marketing The Company manages its risk to changes in the residual value of leased vehicles, office and business equipment, and other assets through disciplined residual valuation setting at the inception of a lease, diversification of its leased assets, regular residual asset valuation reviews and monitoring of residual value gains or losses upon the disposition of assets. Retail lease residual value risk is mitigated further by the purchase of residual value insurance coverage and effective end-of-term off-lease The components of the net investment in sales-type and direct financing leases were as follows: (Dollars in Millions) September 30, December 31, Lease receivables $ 12,150 $ 12,207 Unguaranteed residual values accruing to the lessor’s benefit 1,873 1,877 Total net investment in sales-type and direct financing leases $ 14,023 $ 14,084 The Company, as a lessor, recorded $257 million and $742 million of revenue on its Consolidated Statement of Income for the three and nine months ended September 30, 2019, respectively, primarily consisting of interest income on sales-type and direct financing leases.

Leased assets primarily include retail branches, operations centers and other corporate locations, and, to a lesser extent, office and computer equipment. For each lease with an original term greater than 12 months, the Company records a lease liability and a corresponding right of use (“ROU”) asset. The Company accounts for the lease and non-lease , Certain of the Company’s real estate leases include options to extend. Lease extension options are generally exercisable at market rates. Such option periods do not provide a significant incentive, and their exercise is not reasonably certain. Accordingly, the Company does not recognize payments occurring during option periods in the calculation of its ROU assets and lease liabilities. The Company’s leases do not impose significant covenants or other restrictions on the Company. Total costs incurred by the Company, as a lessee, were $99 million and $294 million for the three and nine months ended September 30, 2019, respectively, and principally related to contractual lease payments on operating leases.

Accounting Policies [Abstract]
Accounting for Transfers and Servicing of Financial Assets and Variable Interest Entities	Note 6 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 7. 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 $8 million and $6 million of support to the funds during the three months ended September 30, 2019 and 2018, 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 $237 million and $202 million, respectively, were included in tax expense and the remaining amounts were included in noninterest expense. 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) September 30, 2019 December 31, 2018 Investment carrying amount $ 6,079 $ 5,823 Unfunded capital and other commitments 3,037 2,778 Maximum exposure to loss 12,163 12,360 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 $30 million at September 30, 2019 and $27 million at December 31, 2018. The maximum exposure to loss related to these VIEs was $55 million at September 30, 2019 and $52 million at December 31, 2018, 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 $89 million at September 30, 2019, compared with less than $1 million to $95 million at December 31, 2018. 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 The Company also sponsors a conduit to which it previously transferred high-grade investment securities. The Company consolidates the conduit because of its ability to manage the activities of the conduit. At September 30, 2019 and December 31, 2018, $ million of the held-to-maturity investment securities on the Company’s Consolidated Balance Sheet were related to the conduit . 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 September 30, 2019, $2.9 billion of available-for-sale available-for-sale

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 13 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 September 30, 2019, the Company had $94 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

Netting Arrangements for Certain Financial Instruments and Securities Financing Activities	Note 14 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 September 30, 2019 Repurchase agreements U.S. Treasury and agencies $ 278 $ – $ – $ – $ 278 Residential agency mortgage-backed securities 270 – – – 270 Corporate debt securities 676 – – – 676 Total repurchase agreements 1,224 – – – 1,224 Securities loaned Corporate debt securities 107 – – – 107 Total securities loaned 107 – – – 107 Gross amount of recognized liabilities $ 1,331 $ – $ – $ – $ 1,331 December 31, 2018 Repurchase agreements U.S. Treasury and agencies $ 134 $ – $ – $ – $ 134 Residential agency mortgage-backed securities 565 – 945 470 1,980 Corporate debt securities 480 – – – 480 Total repurchase agreements 1,179 – 945 470 2,594 Securities loaned Corporate debt securities 227 – – – 227 Total securities loaned 227 – – – 227 Gross amount of recognized liabilities $ 1,406 $ – $ 945 $ 470 $ 2,821 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 Value Disclosures [Abstract]
Fair Values of Assets and Liabilities	Note 15 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 nine months ended September 30, 2019 and 2018, 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 $10 million net gain and a $4 million net loss for the three months ended September 30, 2019 and 2018, respectively, and a $53 million net gain and a $61 million net loss for the nine months ended September 30, 2019 and 2018, 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 7 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 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 shares when there are changes in the conversion rate of the Visa Inc. Class B common shares to Visa Inc. Class A common shares, 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 16 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 September 30, 2019: Minimum Maximum Weighted - Expected prepayment 10 % 21 % 15 % Option adjusted spread 7 10 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 September 30, 2019: Minimum Maximum Weighted - Expected loan close rate 13 % 100 % 78 % Inherent MSR value (basis points per loan) 50 199 118 (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 September 30, 2019, the minimum, maximum and weighted - 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 16 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 Associations”) are defendants in antitrust lawsuits challenging the practices of the Card Associations (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. In September 2018, Visa signed a new settlement agreement, superseding the original settlement agreement, to resolve class action claims associated with the Multi-District Litigation. The new settlement is still subject to court approval. During the three and nine months ended September 30, 2019, the Company sold 0.3 million and 1.0 million, respectively, of its Class B shares. Upon final settlement of the Visa Litigation, the remaining 0.3 million Class B shares held by the Company will be eligible for conversion to Class A shares of Visa Inc., which are publicly traded. The Class B shares are excluded from the Company’s financial instruments disclosures included in Note 15. Other Guarantees and Contingent Liabilities The following table is a summary of other guarantees and contingent liabilities of the Company at September 30, 2019: (Dollars in Millions) Collateral Carrying Maximum Standby letters of credit $ — $ 50 $ 10,608 Third party borrowing arrangements — — 13 Securities lending indemnifications 6,383 — 6,263 Asset sales — 75 7,361 (a) Merchant processing 666 60 112,766 Tender option bond program guarantee 2,868 — 2,595 Minimum revenue guarantees — — 3 Other — 71 1,481 (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, Europe and Mexico 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 September 30, 2019, the value of airline tickets purchased to be delivered at a future date through card transactions processed by the Company was $9.0 billion. The Company held collateral of $581 m 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 , and December , , the Company had reserved $ million for potential losses from representation and warranty obligations. 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 September 30, 2019 and December 31, 2018, the Company had $11 million and $15 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 In the last several years, 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 Company is currently subject to examinations, inquiries and investigations by government agencies and bank regulators concerning mortgage-related practices, including those related to lender-placed insurance, and notices and filings in bankruptcy cases. 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). In February 2018, the Company entered into a deferred prosecution agreement (the “DPA”) with the United States Attorney’s Office in Manhattan that resolved its investigation of the Company concerning a legacy banking relationship between U.S. Bank and payday lending businesses associated with a former customer and U.S. Bank’s legacy Bank Secrecy Act/anti-money laundering compliance program. The DPA defers prosecution for a period of two years, subject to the Company’s compliance with its terms, which include ongoing efforts to implement and maintain an adequate Bank Secrecy Act/anti-money laundering compliance program. If the Company violates the DPA, its term could be extended up to an additional one year, or the Company could be subject to a prosecution or civil action based on the matters that are the subject of the DPA. In addition, the Company and certain of its affiliates entered into related regulatory settlements with the Financial Crimes Enforcement Network and the Board of Governors of the Federal Reserve System. If the Company and its affiliates fail to satisfy ongoing obligations under these regulatory settlements, which include ongoing commitments to provide resources to, and enhance, the Company’s firm wide Bank Secrecy Act/anti-money laundering compliance program, the Company and its affiliates may be required to enter into further orders and settlements, pay additional fines or penalties, or modify their business practices (which may increase operating expenses and decrease 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.

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 policies for the lines of business are generally the same as those used in preparation of the consolidated financial statements with respect to activities specifically attributable to each business line. However, the preparation of business line results requires management to establish methodologies to allocate funding costs, expenses and other financial elements to each line of business. Table 11 “Line of Business Financial Performance” included in Management’s Discussion and Analysis provides details of segment results. This information is incorporated by reference into these Notes to Consolidated Financial Statements.
Accounting Changes	Accounting for Leases Effective January 1, 2019, the Company adopted accounting guidance, issued by the Financial Accounting Standards Board (“FASB”) in February 2016, related to the accounting for leases. This guidance requires lessees to recognize all leases on the Consolidated Balance Sheet as lease assets and lease liabilities based primarily on the present value of future lease payments. The Company recognized approximately $1.3 billion of lease assets and related liabilities on its Consolidated Balance Sheet at the adoption date. In addition, lessors are now required to consider lease residual exposures of sales-type and direct financing leases when determining the allowance for credit losses. The adoption of this guidance was not material to the Company’s Consolidated Statement of Income. Financial Instruments — Credit Losses In June 2016, the FASB issued accounting guidance, related to the impairment of financial instruments which the Company will adopt effective January 1, 2020. This guidance changes existing 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 current accounting guidance by decreasing the n The extent of the impact of this guidance will depend on economic conditions and the composition of the Company’s loan portfolio at the adoption date, as well as further refinements to the Company’s process, judgements and models to quantify credit impairment under the new standard. The Company expects the new standard to increase its allowance for credit losses by $ 1.2 When determining expected losses, the Company uses multiple economic scenarios and a three-year reasonable and supportable forecast period. After the forecast period, the Company reverts to long-term historical loss experience, adjusted for prepayments, to estimate losses over the remaining life. The estimated increase in the allowance is primarily related to the credit card, installment and other retail loan portfolios where the existing allowance for loan losses has been based primarily shorter loss period The Company does not expect its held-to-maturity available-for-sale
Loans and Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses is established for probable and estimable losses incurred in the Company’s loan and lease portfolio, including unfunded credit commitments. 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 incurred losses on a quarterly basis. The allowance recorded for loans in the commercial lending segment is based on reviews of individual credit relationships and considers the migration analysis of commercial lending segment loans and actual loss experience. For each loan type, this historical loss experience is adjusted as necessary to consider any relevant changes in portfolio composition, lending policies, underwriting standards, risk management practices or economic conditions. The results of the analysis are evaluated quarterly to confirm the selected loss experience is appropriate for each commercial loan type. The allowance recorded for impaired loans greater than $5 million in the commercial lending segment is based on an individual loan 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 collateral, less selling costs, for collateral-dependent loans, The allowance recorded for Troubled Debt Restructuring (“TDR”) loans and purchased impaired 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, or the prior quarter effective rate, respectively. 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. The allowance recorded for all other consumer lending segment loans is determined on a homogenous pool basis and includes consideration of product mix, risk characteristics of the portfolio, bankruptcy experience, delinquency status, refreshed loan-to-value In addition, subsequent payment defaults on loan modifications considered TDRs are considered in the underlying factors used in the determination of the appropriateness of the allowance for credit losses. For each loan segment, the Company estimates future loan charge-offs through a variety of analysis, trends and underlying assumptions. 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. With respect to the consumer lending segment, performance of the portfolio, including defaults on TDRs, is considered when estimating future cash flows. 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, in addition to the amounts determined under the methodologies described above, management also considers the potential impact of other qualitative factors which include, but are not limited to, economic factors; geographic and other concentration risks; delinquency and nonaccrual trends; current business conditions; changes in lending policy, underwriting standards and other relevant business practices; results of internal review; and the regulatory environment. The consideration of these items results in adjustments to allowance amounts included in the Company’s allowance for credit losses for each of the above loan segments. The Company also assesses the credit risk associated with off-balance off-balance 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 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. For all loan classes, a loan is considered to be impaired when, based on current events or information, it is probable the Company will be unable to collect all amounts due per the contractual terms of the loan agreement. Impaired loans include all nonaccrual and TDR loans. For all loan classes, interest income on TDR loans is recognized under the modified terms and conditions if the borrower has demonstrated repayment performance at a level commensurate with the modified terms over several payment cycles. Interest income is generally not recognized on other impaired loans until the loan is paid off. However, interest income may be recognized for interest payments if the remaining carrying amount of the loan is believed to be collectible. Factors used by the Company in determining whether all principal and interest payments due on commercial and commercial real estate loans will be collected and, therefore, whether those loans are impaired include, but are not limited to, the financial condition of the borrower, collateral and/or guarantees on the loan, and the borrower’s estimated future ability to pay based on industry, geographic location and certain financial ratios. The evaluation of impairment on residential mortgages, credit card loans and other retail loans is primarily driven by delinquency status of individual loans or whether a loan has been modified, and considers any government guarantee where applicable. 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. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes. 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. Acquired loans restructured after acquisition are not considered TDRs for accounting and disclosure purposes if the loans evidenced credit deterioration as of the acquisition date and are accounted for in pools.
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. 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. 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 September 30, 2019: (Dollars in Millions) Collateral Carrying Maximum Standby letters of credit $ — $ 50 $ 10,608 Third party borrowing arrangements — — 13 Securities lending indemnifications 6,383 — 6,263 Asset sales — 75 7,361 (a) Merchant processing 666 60 112,766 Tender option bond program guarantee 2,868 — 2,595 Minimum revenue guarantees — — 3 Other — 71 1,481 (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.
