Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	NOTE 1 – SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The unaudited Consolidated Financial Statements included within this report have been prepared in accordance with U.S. GAAP to present interim financial statement information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete, consolidated financial statements. However, in the opinion of management, all adjustments, consisting only of normal recurring adjustments that are necessary for a fair presentation of the results of operations in these financial statements, have been made. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes; actual results could vary from these estimates. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. Interim Consolidated Financial Statements should be read in conjunction with the Company’s 2018 Annual Report on Form 10-K. Changes in Significant Accounting Policies Pursuant to the Company’s adoption of ASC Topic 842 as of January 1, 2019, the Company updated its accounting policy related to leases. S ee Note 10 , “Leases,” for new disclosures and policy information related to the Company’s leases. There were no other significant changes to the Company’s accounting policies from those disclosed in the Company’s 2018 Annual Report on Form 10-K that could have a material effect on the Company's financial statements. Subsequent Events The Company evaluated events that occurred between June 30, 2019 and the date the accompanying financial statements were issued, and there were no material events, other than those already discussed in this Form 10-Q, that would require recognition in the Company’s Consolidated Financial Statements or disclosure in the accompanying Notes. Accounting Pronouncements The following table summarizes ASU s issued by the FASB that were adopted during the six months ended June 30, 2019 or not yet adopted as of June 30, 2019 , that could have a material effect on the Company’s financial statements: Standard Description Required Date of Adoption Effect on the Financial Statements or Other Significant Matters Standards Adopted in 2019 ASU 2016-02, Leases (Topic 842) and subsequent related ASUs These ASUs create and amend ASC Topic 842, Leases , which supersedes ASC Topic 840, Leases . ASC Topic 842 requires lessees to recognize right-of-use assets and associated liabilities that arise from leases, with the exception of short-term leases. These ASUs do not make significant changes to lessor accounting; however, there were certain improvements made to align lessor accounting with the lessee accounting model and ASC Topic 606, Revenue from Contracts with Customers . Furthermore, there are several new qualitative and quantitative disclosures required for lessees and lessors, including updated guidance around the presentation of certain cash receipts on the Company’s Consolidated Statements of Cash Flows. January 1, 2019 The Company adopted these ASUs on January 1, 2019, using a modified retrospective transition approach as of the date of adoption, which resulted in the recognition of $1.2 billion and $1.3 billion in right-of-use assets and associated lease liabilities, respectively, arising from operating leases in which the Company is the lessee, on the Company's Consolidated Balance Sheets. The amount of the right-of-use assets and associated lease liabilities recorded upon adoption was based primarily on the present value of unpaid future minimum lease payments, the amount of which was based on the population of leases in effect at the date of adoption. Right-of-use assets and lease liabilities recorded on the Company’s Consolidated Balance Sheets each totaled $1.2 billion at June 30, 2019. Standard Description Required Date of Adoption Effect on the Financial Statements or Other Significant Matters Standards Not Yet Adopted ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326) and subsequent related ASUs These ASUs create and amend ASC Topic 326, Financial Instruments - Credit Losses , which replaces the incurred loss impairment methodology with a current expected credit loss methodology for financial instruments measured at amortized cost and other commitments to extend credit. For this purpose, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of voluntary prepayments and considering available information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. The resulting allowance for credit losses is deducted from the amortized cost basis of the financial assets to reflect the net amount expected to be collected on the financial assets. Additional quantitative and qualitative disclosures are required upon adoption. The change to the allowance for credit losses at the time of the adoption will be made with a cumulative effect adjustment to retained earnings. January 1, 2020 The Company formed a cross-functional team to oversee the implementation of these ASUs. A detailed implementation plan was developed and progress is nearly complete in regards to the identification and staging of data, development and validation of models, refinement of economic forecasting processes, and documentation of accounting policy decisions. Additionally, a new credit loss forecasting process has been implemented. In conjunction with this implementation, the Company modified the internal control environment, as appropriate. In the first half of 2019, the Company performed testing in which methodologies, processes, and internal controls were evaluated and refined. The Company will perform full parallel runs of the new methodology in the third and fourth quarters of 2019. The full parallel runs will emulate a regular estimation process including internal controls, supporting analytics, reserve estimation, documentation, subject matter expert reviews, and execution of the governance and approval process. Based on the results of these full parallel runs, the Company plans to further refine its processes and methodology prior to the adoption of these ASUs. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment This ASU amends ASC Topic 350, Intangibles - Goodwill and Other , to simplify the subsequent measurement of goodwill, by eliminating Step 2 from the goodwill impairment test. The amendments require an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. This ASU requires an entity to recognize an impairment charge for the amount by which a reporting unit's carrying amount exceeds its fair value, with the loss limited to the total amount of goodwill allocated to that reporting unit. The ASU must be applied on a prospective basis. January 1, 2020 Early adoption is permitted. Based on the Company’s most recent qualitative goodwill impairment assessment performed as of October 1, 2018, there were no reporting units for which it was more-likely-than-not that the carrying amount of a reporting unit exceeded its respective fair value; therefore, this ASU would not currently have an impact on the Company’s Consolidated Financial Statements or related disclosures. However, if subsequent to adoption, the carrying amount of a reporting unit exceeds its respective fair value, the Company would be required to recognize an impairment charge for the amount that the carrying value exceeds the fair value. ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This ASU amends ASC Subtopic 350-40, Intangibles - Goodwill and Other - Internal-Use Software , to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company may apply this ASU either retrospectively, or prospectively to all implementation costs incurred after the date of adoption. January 1, 2020 Early adoption is permitted. The Company’s current accounting policy for capitalizing implementation costs incurred in a hosting arrangement generally aligns with the requirements of this ASU; therefore, the Company's adoption of this ASU is not expected to have a material impact on the Company’s Consolidated Financial Statements or related disclosures.

Securities borrowed are primarily collateralized by corporate securities. The Company borrows securities and purchases securities under agreements to resell as part of its securities financing activities. On the acquisition date of these securities, the Company and the related counterparty agree on the amount of collateral required to secure the principal amount loaned under these arrangements. The Company monitors collateral values daily and calls for additional collateral to be provided as warranted under the respective agreements. At June 30, 2019 and December 31, 2018 , the total market value of collateral held was $1.2 billion and $1.6 billion , of which $136 million and $108 million was repledged, respectively. Securities Sold Under Agreements to Repurchase Securities sold under agreements to repurchase are accounted for as secured borrowings. The following table presents the Company’s related activity, by collateral type and remaining contractual maturity: June 30, 2019 December 31, 2018 (Dollars in millions) Overnight and Continuous Up to 30 days Total Overnight and Continuous Up to 30 days 30-90 days Total U.S. Treasury securities $122 $— $122 $197 $7 $— $204 Federal agency securities 23 9 32 112 10 — 122 MBS - agency residential 898 148 1,046 881 35 — 916 CP 108 — 108 78 — — 78 Corporate and other debt securities 238 268 506 216 158 80 454 Total securities sold under agreements to repurchase $1,389 $425 $1,814 $1,484 $210 $80 $1,774 For securities sold under agreements to repurchase, the Company would be obligated to provide additional collateral in the event of a significant decline in fair value of the collateral pledged. This risk is managed by monitoring the liquidity and credit quality of the collateral, as well as the maturity profile of the transactions. Netting of Securities - Repurchase and Resell Agreements The Company has various financial assets and financial liabilities that are subject to enforceable master netting agreements or similar agreements. The Company's derivatives that are subject to enforceable master netting agreements or similar agreements are discussed in Note 16 , “Derivative Financial Instruments.” The following table presents the Company's securities borrowed or purchased under agreements to resell and securities sold under agreements to repurchase that are subject to MRA s. Generally, MRA s require collateral to exceed the asset or liability recognized on the balance sheet. Transactions subject to these agreements are treated as collateralized financings, and those with a single counterparty are permitted to be presented net on the Company's Consolidated Balance Sheets, provided certain criteria are met that permit balance sheet netting. At June 30, 2019 and December 31, 2018 , there were no such transactions subject to legally enforceable MRA s that were eligible for balance sheet netting. The following table includes the amount of collateral pledged or received related to exposures subject to enforceable MRA s. While these agreements are typically over-collateralized, the amount of collateral presented in this table is limited to the amount of the related recognized asset or liability for each counterparty.

At June 30, 2019 and December 31, 2018 , the Company had $32.2 billion and $28.1 billion of net eligible loan collateral pledged to the Federal Reserve discount window to support $24.1 billion and $21.3 billion of available, unused borrowing capacity, respectively. At June 30, 2019 and December 31, 2018 , the Company had $39.4 billion and $39.2 billion of net eligible loan collateral pledged to the FHLB of Atlanta to support $31.9 billion and $31.0 billion of available borrowing capacity, respectively. The available FHLB borrowing capacity at June 30, 2019 was used to support $9.8 billion of advances and $4.2 billion of letters of credit issued on the Company's behalf. At December 31, 2018 , the available FHLB borrowing capacity was used to support $5.0 billion of advances and $5.8 billion of letters of credit issued on the Company's behalf. Credit Quality Evaluation The Company evaluates the credit quality of its LHFI portfolio by employing a dual internal risk rating system, which assigns both PD and LGD ratings to derive expected losses. Assignment of these ratings are predicated upon numerous factors, including consumer credit risk scores, rating agency information, borrower/guarantor financial capacity, LTV ratios, collateral type, debt service coverage ratios, collection experience, other internal metrics/analyses, and/or qualitative assessments. For the commercial portfolio, the Company believes that the most appropriate credit quality indicator is an individual loan’s risk assessment expressed according to the broad regulatory agency classifications of Pass or Criticized. The Company conforms to the following regulatory classifications for Criticized assets: Other Assets Especially Mentioned (or Special Mention), Substandard, Doubtful, and Loss. However, for the purposes of disclosure, management believes the most meaningful distinction within the Criticized categories is between Criticized accruing (which includes Special Mention and a portion of Substandard) and Criticized nonaccruing (which includes a portion of Substandard as well as Doubtful and Loss). This distinction identifies those relatively higher risk loans for which there is a basis to believe that the Company will not collect all amounts due under those loan agreements. The Company's risk rating system is more granular, with multiple risk ratings in both the Pass and Criticized categories. Pass ratings reflect relatively low PD s; whereas, Criticized assets have higher PD s. The granularity in Pass ratings assists in establishing pricing, loan structures, approval requirements, reserves, and ongoing credit management requirements. Commercial risk ratings are refreshed at least annually, or more frequently as appropriate, based upon considerations such as market conditions, borrower characteristics, and portfolio trends. Additionally, management routinely reviews portfolio risk ratings, trends, and concentrations to support risk identification and mitigation activities. As reflected in the following risk rating table, the increases in Pass and Criticized accruing C&I loans at June 30, 2019 compared to December 31, 2018 , were due to loan growth and normal variability in the portfolio. Criticized nonaccruing C&I loans remained low relative to accruing loans. For consumer loans, the Company monitors credit risk based on indicators such as delinquencies and FICO scores. The Company believes that consumer credit risk, as assessed by the industry-wide FICO scoring method, is a relevant credit quality indicator. Borrower-specific FICO scores are obtained at origination as part of the Company’s formal underwriting process, and refreshed FICO scores are obtained by the Company at least quarterly. For guaranteed loans, the Company monitors the credit quality based primarily on delinquency status, as it is a more relevant indicator of credit quality due to the government guarantee. At June 30, 2019 and December 31, 2018 , 28% and 27% , respectively, of guaranteed residential mortgages were current with respect to payments. At June 30, 2019 and December 31, 2018 , 76% and 72% , respectively, of guaranteed student loans were current with respect to payments. The Company's loss exposure on guaranteed residential mortgages and student loans is mitigated by the government guarantee.

Impaired Loans A loan is considered impaired when it is probable that the Company will be unable to collect all amounts due, including principal and interest, according to the contractual terms of the agreement. Commercial nonaccrual loans greater than $3 million and certain commercial and consumer LHFI whose terms have been modified in a TDR are individually evaluated for impairment. Smaller-balance homogeneous LHFI that are collectively evaluated for impairment and LHFI measured at fair value are not included in the following tables.

Proceeds due from the FHA and the VA are recorded as a receivable in Other assets in the Consolidated Balance Sheets until the property is conveyed and the funds are received. The receivable related to proceeds due from the FHA and the VA totaled $51 million and $50 million at June 30, 2019 and December 31, 2018 , respectively. The Company's recorded investment of nonaccruing LHFI secured by residential real estate properties for which formal foreclosure proceedings were in process at June 30, 2019 and December 31, 2018 was $82 million and $93 million , respectively. The Company's recorded investment of accruing LHFI secured by residential real estate properties for which formal foreclosure proceedings were in process at June 30, 2019 and December 31, 2018 was $102 million and $110 million , of which $95 million and $103 million were insured by the FHA or guaranteed by the VA , respectively. At June 30, 2019 , OREO included $53 million of foreclosed residential real estate properties and $1 million of foreclosed commercial real estate properties, with the remaining $1 million related to land. At December 31, 2018 , OREO included $50 million of foreclosed residential real estate properties and $2 million of foreclosed commercial real estate properties, with the remaining $2 million related to land. Restructured Loans A TDR is a loan for which the Company has granted an economic concession to a borrower in response to financial difficulty experienced by the borrower, which the Company would not have considered otherwise. When a loan is modified under the terms of a TDR, the Company typically offers the borrower an extension of the loan maturity date and/or a reduction in the original contractual interest rate. In limited situations, the Company may offer to restructure a loan in a manner that ultimately results in the forgiveness of a contractually specified principal balance. At both June 30, 2019 and December 31, 2018 , the Company had an immaterial amount of commitments to lend additional funds to debtors whose terms have been modified in a TDR. The number and carrying value of loans modified under the terms of a TDR, by type of modification, are presented in the following tables: Three Months Ended June 30, 2019 1 (Dollars in millions) Number of Loans Modified Rate Modification Term Extension and/or Other Concessions Total Commercial loans: C&I 22 $— $2 $2 Consumer loans: Residential mortgages - nonguaranteed 27 1 2 3 Residential home equity products 77 — 5 5 Other direct 268 — 5 5 Indirect 553 — 14 14 Credit cards 555 3 — 3 Total TDR additions 1,502 $4 $28 $32 1 Includes loans modified under the terms of a TDR that were charged-off during the period.

TDRs that defaulted during the three and six months ended June 30, 2019 and 2018 , which were first modified within the previous twelve months, were immaterial. The majority of lo ans that were modified under the terms of a TDR and subsequently became 90 days or more delinquent have remained on nonaccrual status since the time of delinquency. Concentrations of Credit Risk The Company does not have a significant concentration of credit risk to any individual client except for the U.S. government and its agencies. However, a geographic concentration arises because the majority of the Company's LHFI portfolio represents borrowers that reside in Florida, Georgia, Virginia, Maryland, and North Carolina . The Company’s cross-border outstanding loans totaled $1.8 billion at both June 30, 2019 and December 31, 2018 . With respect to collateral concentration, the Company's recorded investment in residential real estate secured LHFI totaled $38.3 billion at June 30, 2019 and represented 24% of total LHFI. At December 31, 2018 , the Company's recorded investment in residential real estate secured LHFI totaled $38.9 billion and represented 26% of total LHFI. Additionally, at June 30, 2019 and December 31, 2018 , the Company had commitments to extend credit on home equity lines of $10.6 billion and $10.3 billion , and had residential mortgage commitments outstanding of $5.3 billion and $2.7 billion , respectively. At both June 30, 2019 and December 31, 2018 , 1% of the Company's LHFI secured by residential real estate was insured by the FHA or guaranteed by the VA .

Investment Securities in an Unrealized Loss Position The Company held certain investment securities where amortized cost exceeded fair value, resulting in unrealized loss positions. Market changes in interest rates and credit spreads may result in temporary unrealized losses as the market prices of securities fluctuate. At June 30, 2019 , the Company did not intend to sell these securities nor was it more-likely-than-not that the Company would be required to sell these securities before their anticipated recovery or maturity. The Company reviewed its portfolio for OTTI in accordance with the accounting policies described in Note 1 , "Significant Accounting Policies," to the Company's 2018 Annual Report on Form 10-K . Investment securities in an unrealized loss position at period end are presented in the following tables: June 30, 2019 Less than twelve months Twelve months or longer Total (Dollars in millions) Fair Unrealized 1 Fair Unrealized 1 Fair Unrealized 1 Temporarily impaired securities AFS: U.S. Treasury securities $— $— $50 $— $50 $— Federal agency securities — — 28 — 28 — U.S. states and political subdivisions 4 — 188 1 192 1 MBS - agency residential — — 2,540 17 2,540 17 MBS - agency commercial 52 — 575 8 627 8 MBS - non-agency commercial — — 12 — 12 — Corporate and other debt securities — — 6 — 6 — Total temporarily impaired securities AFS 56 — 3,399 26 3,455 26 OTTI securities AFS 2 : Total OTTI securities AFS — — — — — — Total impaired securities AFS $56 $— $3,399 $26 $3,455 $26 1 Unrealized losses less than $0.5 million are presented as zero within the table. 2 OTTI securities AFS are impaired securities for which OTTI credit losses have been previously recognized in earnings.

The Company does not consider the unrealized losses on temporarily impaired securities AFS to be credit-related. These unrealized losses were due primarily to market interest rates being higher than the securities' stated coupon rates, and therefore, they were recorded in AOCI, net of tax. Realized Gains and Losses and Other-Than-Temporarily Impaired Securities Net securities gains or losses are comprised of gross realized gains, gross realized losses, and OTTI credit losses recognized in earnings. During the three and six months ended June 30, 2019, the Company recognized $42 million in net securities losses due to the Company's repositioning of a portion of the securities AFS portfolio in the second quarter of 2019. This repositioning was not due to any requirement to sell the securities before their anticipated recovery or maturity. Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2019 2018 2019 2018 Gross realized gains $— $6 $— $7 Gross realized losses (42 ) (6 ) (42 ) (6 ) OTTI credit losses recognized in earnings — — — — Net securities (losses)/gains ($42 ) $— ($42 ) $1 Investment securities in an unrealized loss position are evaluated quarterly for other-than-temporary credit impairment, which is determined using cash flow analyses that take into account security specific collateral and transaction structure. Future expected credit losses are determined using various assumptions, the most significant of which include default rates, prepayment rates, and loss severities. If, based on this analysis, a security is in an unrealized loss position and the Company does not expect to recover the entire amortized cost basis of the security, the expected cash flows are then discounted at the security’s initial effective interest rate to arrive at a present value amount. Credit losses on the OTTI security are recognized in earnings and reflect the difference between the present value of cash flows expected to be collected and the amortized cost basis of the security. Subsequent credit losses may be recorded on OTTI securities without a corresponding further decline in fair value when there has been a decline in expected cash flows. See Note 1 , "Significant Accounting Policies," to the Company's 2018 Annual Report on Form 10-K for additional information regarding the Company's accounting policy on securities AFS and related impairments. The Company seeks to reduce its exposure on any existing OTTI securities primarily through paydowns. In certain instances, the amount of credit losses recognized in earnings on a debt security exceeds the total unrealized losses on the security, which may result in unrealized gains relating to factors other than credit recorded in AOCI, net of tax. During the three and six months ended June 30, 2019 and 2018 , there were no credit impairment losses recognized on securities AFS held at the end of the period. The accumulated balance of OTTI credit losses recognized in earnings on securities AFS held at period end was zero at both June 30, 2019 and 2018 .

As discussed in Note 1 , “Significant Accounting Policies,” to the Company's 2018 Annual Report on Form 10-K , the ALLL is composed of both specific allowances for certain nonaccrual loans and TDRs, and general allowances for groups of LHFI with similar risk characteristics. No allowance is required for LHFI measured at fair value. Additionally, the Company records an immaterial allowance for LHFI products that are insured by federal agencies or guaranteed by GSE s, as there is nominal risk of principal loss.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	NOTE 8 – GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill The Company conducts a qualitative goodwill assessment at the reporting unit level at least quarterly, or more frequently as events occur or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. The Company performed a qualitative goodwill assessment for the Consumer and Wholesale reporting units in the first and second quarters of 2019, and concluded that a quantitative goodwill impairment test was not necessary for either reporting unit as it was more-likely-than-not that the fair value of both reporting units were greater than their respective carrying amounts. See Note 1 , “Significant Accounting Policies,” to the Company's 2018 Annual Report on Form 10-K for additional information and the Company’s goodwill accounting policy. There were no changes in the carrying amount of goodwill by reportable segment for the six months ended June 30, 2019 . Changes in the carrying amount of goodwill by reportable segment for the six months ended June 30, 2018 are presented in the following table.

Servicing Rights The Company acquires servicing rights and retains servicing rights for certain of its sales or securitizations of residential mortgages and commercial loans. Servicing rights on residential and commercial mortgages are capitalized by the Company and are classified as Other intangible assets on the Company's Consolidated Balance Sheets. Residential Mortgage Servicing Rights Income earned by the Company on its residential MSRs is derived primarily from contractually specified mortgage servicing fees and late fees, net of curtailment costs, and is presented in the following table. Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2019 2018 2019 2018 Income from residential MSRs 1 $110 $107 $221 $214 1 Recognized in Mortgage-related income in the Consolidated Statements of Income. The UPB of residential mortgage loans serviced for third parties is presented in the following table: (Dollars in millions) June 30, 2019 December 31, 2018 UPB of loans underlying residential MSRs $136,762 $140,801 No MSRs on residential loans were purchased during the six months ended June 30, 2019 . The Company purchased MSRs on residential loans with a UPB of $5.9 billion during the six months ended June 30, 2018 . During the six months ended June 30, 2019 and 2018 , the Company sold MSRs on residential loans, at a price approximating their fair value, with a UPB of $567 million and $221 million , respectively. The Company measures the fair value of its residential MSRs using a valuation model that calculates the present value of estimated future net servicing income using prepayment projections, spreads, and other assumptions. The Consumer Valuation Committee reviews and approves all significant assumption changes at least annually, drawing upon various market and empirical data sources. Changes to valuation model inputs are reflected in the periods’ results. See Note 17 , “Fair Value Election and Measurement,” for further information regarding the Company’s residential MSR valuation methodology. A summary of the significant unobservable inputs used to estimate the fair value of the Company’s residential MSRs and the uncertainty of the fair values in response to 10% and 20% adverse changes in those inputs at the reporting date are presented in the following table. (Dollars in millions) June 30, 2019 December 31, 2018 Fair value of residential MSRs $1,717 $1,983 Prepayment rate assumption (annual) 14 % 13 % Decline in fair value from 10% adverse change $99 $96 Decline in fair value from 20% adverse change 187 183 Option adjusted spread (annual) 3 % 2 % Decline in fair value from 10% adverse change $36 $44 Decline in fair value from 20% adverse change 71 86 Weighted-average life (in years) 4.9 5.5 Weighted-average coupon 4.1 % 4.0 % Residential MSR uncertainties are hypothetical and should be used with caution. Changes in fair value based on variations in assumptions generally cannot be extrapolated because (i) the relationship of the change in an assumption to the change in fair value may not be linear and (ii) changes in one assumption may result in changes in another, which might magnify or counteract the uncertainties. The uncertainties do not reflect the effect of hedging activity undertaken by the Company to offset changes in the fair value of MSRs. See Note 16 , “Derivative Financial Instruments,” for further information regarding these hedging activities. Commercial Mortgage Servicing Rights Income earned by the Company on its commercial MSRs is derived primarily from contractually specified servicing fees and other ancillary fees. The Company also earns income from subservicing certain third party commercial mortgages for which the Company does not record servicing rights. The following table presents the Company’s income earned from servicing commercial mortgages. Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2019 2018 2019 2018 Income from commercial MSRs 1 $6 $7 $12 $14 Income from subservicing third party commercial mortgages 1 6 3 9 6 1 Recognized in Commercial real estate-related income in the Consolidated Statements of Income.

Commercial MSRs are accounted for at amortized cost and are monitored for impairment on an ongoing basis. The Company calculates the fair value of commercial MSRs based on the present value of estimated future net servicing income, considering prepayment projections and other assumptions. Impairment, if any, is recognized when the carrying value of the servicing asset exceeds the fair value at the measurement date. The amortized cost of the Company’s commercial MSRs was $66 million at both June 30, 2019 and December 31, 2018 . A summary of the significant unobservable inputs used to estimate the fair value of the Company’s commercial MSRs and the uncertainty of the fair values in response to 10% and 20% adverse changes in those inputs at the reporting date, are presented in the following table.

Leases [Abstract]
Leases of Lessee and Lessor Disclosure [Text Block]	NOTE 10 - LEASES The Company adopted ASC Topic 842, Leases , on January 1, 2019 using a modified retrospective transition approach. As permitted by ASC 842, the Company elected not to reassess (i) whether any expired or existing contracts are leases or contain leases, (ii) the lease classification of any expired or existing leases, and (iii) the initial direct costs for existing leases. Lessee Accounting The Company's right-of-use assets, lease liabilities, and associated balance sheet classifications are presented in the following table: (Dollars in millions) Classification June 30, 2019 Assets: Operating lease right-of-use assets Other assets $1,128 Finance lease right-of-use assets Premises, property, and equipment, net 25 Total right-of-use assets $1,153 Liabilities: Operating leases Other liabilities $1,205 Finance leases Long-term debt 27 Total lease liabilities $1,232 The Company leases certain assets, consisting primarily of real estate, and assesses at contract inception whether a contract is, or contains, a lease. A right-of-use asset and lease liability is recorded on the balance sheet for all leases except those with an original lease term of twelve months or less. The Company's leases typically have lease terms between five years and ten years , with the longest lease term having an expiration date in 2081. Most of these leases include one or more renewal options for five years or less, and certain leases also include lessee termination options. At lease commencement, the Company assesses whether it is reasonably certain to exercise a renewal option, or reasonably certain not to exercise a termination option, by considering various economic factors. Options that are reasonably certain of being exercised are factored into the determination of the lease term, and related payments are included in the calculation of the right-of-use asset and lease liability. The Company uses its incremental borrowing rate to calculate the present value of lease payments when the interest rate implicit in a lease is not disclosed. Variable lease payments that are linked to a certain rate or index, such as the CPI , are included in the present value of lease payments and measured using the prevailing rate or index at lease commencement, with changes in the associated rate or index recognized in earnings during the period in which the change occurs. The right-of-use asset and lease liability are not remeasured as a result of any subsequent change in the index or rate unless remeasurement is required for another reason. Variable lease payments that are not linked to a certain rate or index are comprised primarily of operating costs. The Company accounts for each separate lease component of a contract and its associated non-lease components as a single lease component for all of its real estate leases. At June 30, 2019 , the Company had operating leases that had not yet commenced with undiscounted cash flows totaling less than $100 million . Leases that do not commence until a future date generally include executed ground and office space leases where construction is underway and the Company does not control the underlying asset during the construction . The components of total lease cost and other supplemental lease information are presented in the following tables: (Dollars in millions) Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 Components of total lease cost: Operating lease cost $51 $103 Finance lease cost: Amortization of right-of-use assets 1 2 Variable lease cost 9 17 Less: Sublease income (2 ) (3 ) Total lease cost, net $59 $119 (Dollars in millions) Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 Supplemental lease information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $48 $97 Financing cash flows from finance leases 1 2 Lease liabilities arising from obtaining right-of-use assets (subsequent to adoption): Operating leases 5 24 Finance leases 11 11 Weighted average remaining lease terms and discount rates are presented in the following table: (Dollars in millions) June 30, 2019 Weighted-average remaining lease term (in years): Operating leases 8.2 Finance leases 7.0 Weighted-average discount rate (annual): Operating leases 3.3 % Finance leases 6.6 The following table presents a maturity analysis of the Company's operating and finance lease liabilities at June 30, 2019 : (Dollars in millions) Operating Leases Finance Leases Total Year 1 $184 $5 $189 Year 2 191 5 196 Year 3 178 5 183 Year 4 160 6 166 Year 5 140 3 143 Thereafter 544 12 556 Total lease payments 1,397 36 1,433 Less: Imputed interest (192 ) (9 ) (201 ) Present value of lease liabilities $1,205 $27 $1,232 Lessor Accounting The Company’s two primary lessor businesses are equipment financing and structured real estate. In addition, the Company is the lessor in circumstances where a portion of its corporate owned real estate is leased to other tenants. Payment terms are typically fixed; however, some agreements contain variable lease payments linked to an index or rate, such as the CPI or LIBOR . In certain agreements, lease payments increase based on a fixed percentage after a set duration of time. Variable lease payments that are based on an index or rate are included in the net lease investment for sales-type or direct financing leases, and are included in lease receivables for operating leases using the prevailing index or rate at lease commencement. The Company has elected to exclude its sales tax collection and remission activity from being reported as lease revenue with an associated expense. The Company’s leases generally do not contain non-lease components. If a lease does contain non-lease components, the Company has elected not to separate lease and non-lease components for each class of underlying asset in which it is the lessor, when the timing and patterns of revenue recognition for the components are the same, and the lease component, if accounted for separately, would be classified as an operating lease. Equipment Financing The Company finances various types of essential-use business equipment, such as transportation and construction equipment, under operating, sales-type, and direct financing leases. Lease terms are generally noncancelable and range between three years and fifteen years . Most lease agreements contain renewal options that range from one month to three years , and are generally reset at the effective fair market value at time of renewal. Certain lease agreements also include an option to purchase the lease asset at least twelve months prior to the end of the lease term. The Company evaluates various inputs when estimating the amount it expects to derive from the underlying asset following the end of the lease term, including but not limited to, appraisals and inputs from third party sources, and historical portfolio experience. The Company manages residual risk on an individual lease basis, and in certain cases, obtains lessee residual value guarantees or enters into remarketing agreements in the event of lessee default or lease termination. The Company performs a review of residual risk annually and obtains a third party appraisal for the majority of leased assets. At June 30, 2019 , the carrying amount of residual assets covered by residual value guarantees was $108 million . Structured Real Estate The Company offers structured real estate arrangements, including build-to-suit arrangements, whereby real property is leased to corporate clients under operating, sales-type, and direct financing leases. These leases typically have noncancelable terms that range between fifteen years and twenty years as well as multiple renewal options that can extend a lease up to an additional twenty years . These leases generally do not have termination or purchase options. When a lease asset is acquired, the amount the Company expects to derive from the underlying asset is estimated using property appraisal values and assumptions regarding the economic life of the asset. The Company manages residual risk through continuous monitoring of the associated asset and credit quality of the lessee, which may include site visits to view the property and surrounding area. In certain cases, the Company may obtain third party residual value guarantees. In most instances, there are no lessee residual value guarantees. Assets are reviewed at least annually for impairment. At June 30, 2019 , the carrying amount of residual assets covered by residual value guarantees was $29 million . The components of total lease income are presented in the following table: (Dollars in millions) Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 Interest income from sales-type and direct financing leases $37 $74 Lease income relating to operating leases 52 106 Lease income relating to variable lease payments not included in the measurement of the lease receivable 1 2 Total lease income $90 $182 Components of the Company's net investment in sales-type and direct financing leases are presented in the following table: (Dollars in millions) June 30, 2019 Carrying amount of lease receivables $3,807 Unguaranteed residual assets 149 Net investment in sales-type and direct financing lease assets 1 $3,956 1 Included in Loans held for sale and Loans held for investment on the Company's Consolidated Balance Sheets.

Certain Transfers of Financial

Certain Transfers of Financial Assets and Variable Interest Entities	6 Months Ended
	Jun. 30, 2019
Certain Transfers of Financial Assets and Variable Interest Entities [Abstract]
Transfers and Servicing of Financial Assets [Text Block]	NOTE 11 - CERTAIN TRANSFERS OF FINANCIAL ASSETS AND VARIABLE INTEREST ENTITIES The Company has transferred loans and securities in sale or securitization transactions for which the Company retains certain beneficial interests, servicing rights, and/or recourse. These transfers of financial assets include certain residential mortgage loans, guaranteed student loans, and commercial loans, as discussed in the following section, "Transfers of Financial Assets." Cash receipts on beneficial interests held related to these transfers were immaterial for the three and six months ended June 30, 2019 and 2018 . When a transfer or other transaction occurs with a VIE, the Company first determines whether it has a VI in the VIE. A VI is typically in the form of securities representing retained interests in transferred assets and, at times, servicing rights, and for commercial mortgage loans sold to Fannie Mae , the loss share guarantee. See Note 15 , “Guarantees,” for further discussion of the Company's loss share guarantee. When determining whether to consolidate the VIE, the Company evaluates whether it is a primary beneficiary which has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE, and (ii) the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE . To determine whether a transfer should be accounted for as a sale or a secured borrowing, the Company evaluates whether: (i) the transferred assets are legally isolated, (ii) the transferee has the right to pledge or exchange the transferred assets, and (iii) the Company has relinquished effective control of the transferred assets. If all three conditions are met, then the transfer is accounted for as a sale. Except as specifically noted herein, the Company is not required to provide additional financial support to any of the entities to which the Company has transferred financial assets, nor has the Company provided any support it was not otherwise obligated to provide. No events occurred during the six months ended June 30, 2019 that changed the Company’s previous conclusions regarding whether it is the primary beneficiary of the VIEs described herein. Furthermore, no events occurred during the six months ended June 30, 2019 that changed the Company’s sale conclusion with regards to previously transferred residential mortgage loans, guaranteed student loans, or commercial loans. Transfers of Financial Assets The following discussion summarizes transfers of financial assets to entities for which the Company has retained some level of continuing involvement. Consumer Loans Residential Mortgage Loans The Company typically transfers first lien residential mortgage loans in conjunction with Ginnie Mae , Fannie Mae , and Freddie Mac securitization transactions, whereby the loans are exchanged for cash or securities that are readily redeemable for cash, and servicing rights are retained. The Company sold residential mortgage loans to Ginnie Mae , Fannie Mae , and Freddie Mac , which resulted in pre-tax net gains of $67 million and $116 million for the three and six months ended June 30, 2019 , and pre-tax net gains of $19 million and $7 million for the three and six months ended June 30, 2018 , respectively. Net gains/losses on the sale of residential mortgage LHFS are recorded at inception of the associated IRLCs and reflect the change in value of the loans resulting from changes in interest rates from the time the Company enters into the related IRLCs with borrowers until the loans are sold, but do not include the results of hedging activities initiated by the Company to mitigate this market risk. See Note 16 , "Derivative Financial Instruments," for further discussion of the Company's hedging activities. The Company has made certain representations and warranties with respect to the transfer of these loans. See Note 15 , “Guarantees,” for additional information regarding representations and warranties. Guaranteed Student Loans The Company has securitized government-guaranteed student loans through a transfer of loans to a securitization entity and retained the residual interest in the entity. The Company concluded that this entity should be consolidated because the Company has (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses, and the right to receive benefits, that could potentially be significant. At June 30, 2019 and December 31, 2018 , the Company’s Consolidated Balance Sheets reflected $153 million and $165 million of assets held by the securitization entity and $149 million and $161 million of debt issued by the entity, respectively, inclusive of related accrued interest. To the extent that the securitization entity incurs losses on its assets, the securitization entity has recourse to the guarantor of the underlying loan, which is backed by the Department of Education up to a maximum guarantee of 98% , or in the event of death, disability, or bankruptcy, 100% . When not fully guaranteed, losses reduce the amount of available cash payable to the Company as the owner of the residual interest. To the extent that losses result from a breach of servicing responsibilities, the Company, which functions as the master servicer, may be required to repurchase the defaulted loan(s) at par value. If the breach was caused by the subservicer, the Company would seek reimbursement from the subservicer up to the guaranteed amount. The Company’s maximum exposure to loss related to the securitization entity would arise from a breach of its servicing responsibilities. To date, loss claims filed with the guarantor that have been denied due to servicing errors have either been, or are in the process of being cured, or reimbursement has been provided to the Company by the subservicer, or in limited cases, absorbed by the Company. Commercial Loans The Company originates and sells certain commercial mortgage loans to Fannie Mae and Freddie Mac , originates FHA insured loans, and issues and sells Ginnie Mae commercial MBS secured by FHA insured loans. The Company transferred commercial loans to these Agencies and GSE s, which resulted in pre-tax net gains of $11 million and $18 million for the three and six months ended June 30, 2019 , and pre-tax net gains of $5 million and $14 million for the three and six months ended June 30, 2018 , respectively. The loans are exchanged for cash or securities that are readily redeemable for cash, with servicing rights retained. The Company has made certain representations and warranties with respect to the transfer of these loans and has entered into a loss share guarantee related to certain loans transferred to Fannie Mae . See Note 15 , “Guarantees,” for additional information regarding the commercial mortgage loan loss share guarantee. The Company's total managed loans, including the LHFI portfolio and other transferred loans (securitized and unsecuritized), are presented in the following table by portfolio balance and delinquency status (accruing loans 90 days or more past due and all nonaccrual loans) at June 30, 2019 and December 31, 2018 , as well as the related net charge-offs for the three and six months ended June 30, 2019 and 2018 . Portfolio Balance Past Due and Nonaccrual Net Charge-offs June 30, December 31, 2018 June 30, December 31, 2018 Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2019 2018 2019 2018 LHFI portfolio: Commercial $83,991 $80,940 $274 $175 $16 $17 $44 $34 Consumer 72,598 70,899 1,738 2,003 69 56 138 118 Total LHFI portfolio 156,589 151,839 2,012 2,178 85 73 182 152 Managed securitized loans: Commercial 1 6,732 6,399 — — — — — — Consumer 136,289 139,809 148 146 1 2 1 2 1 2 3 2 Total managed securitized loans 143,021 146,208 148 146 1 1 1 3 Managed unsecuritized loans 3 561 1,134 67 152 — — — — Total managed loans $300,171 $299,181 $2,227 $2,476 $86 $74 $183 $155 1 Comprised of commercial mortgages sold through Fannie Mae , Freddie Mac , and Ginnie Mae securitizations, whereby servicing has been retained by the Company. 2 Amounts associated with $308 million and $387 million of managed securitized loans at June 30, 2019 and December 31, 2018 , respectively. Net charge-off data is not reported to the Company for the remaining balance of $136.0 billion and $139.4 billion of managed securitized loans at June 30, 2019 and December 31, 2018 , respectively. 3 Comprised of unsecuritized loans the Company originated and sold to private investors with servicing rights retained. Net charge-offs on these loans are not presented in the table as the data is not reported to the Company by the private investors that own these related loans. Other Variable Interest Entities In addition to exposure to VIEs arising from transfers of financial assets, the Company also has involvement with VIEs from other business activities. Tax Credit Investments The following table presents information related to the Company's investments in tax credit VIEs that it does not consolidate: Community Development Investments Renewable Energy Partnerships (Dollars in millions) June 30, 2019 December 31, 2018 June 30, 2019 December 31, 2018 Carrying value of investments 1 $1,765 $1,636 $53 $86 Maximum exposure to loss related to investments 2 2,496 2,207 96 138 1 At June 30, 2019 and December 31, 2018 , the carrying value of community development investments excludes $70 million and $68 million of investments in funds that do not qualify for tax credits, respectively. 2 At June 30, 2019 and December 31, 2018 , the Company's maximum exposure to loss related to community development investments includes $697 million and $422 million of loans and $572 million and $639 million of unfunded equity commitments, respectively. At June 30, 2019 and December 31, 2018 , the Company's maximum exposure to loss related to renewable energy partnerships includes $43 million and $52 million of unfunded equity commitments, respectively. Community Development Investments The Company invests in multi-family affordable housing partnership developments and other community development entities as a limited partner and/or a lender. The carrying value of these investments is recorded in Other assets on the Company’s Consolidated Balance Sheets. The Company receives tax credits for its limited partner investments, which are recorded in Provision for income taxes in the Company's Consolidated Statements of Income. Amortization recognized on qualified affordable housing partnerships is recorded in the Provision for income taxes, net of the related tax benefits, in the Company's Consolidated Statements of Income. Amortization recognized on other community development investments is recorded in Amortization in the Company's Consolidated Statements of Income. The Company has determined that the majority of the related partnerships are VIEs. The Company has concluded that it is not the primary beneficiary of these investments when it invests as a limited partner and there is a third party general partner. The general partner, or an affiliate of the general partner, often provides guarantees to the limited partner, which protects the Company from construction and operating losses and tax credit allocation deficits. The Company’s maximum exposure to loss would result from the loss of its limited partner investments, net of liabilities, along with loans or interest rate swap exposures related to these investments as well as unfunded equity commitments that the Company is required to fund if certain conditions are met. The following table presents tax credits and amortization associated with the Company’s investments in community development investments: Tax Credits Amortization Three Months Ended June 30 Six Months Ended June 30 Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2019 2018 2019 2018 2019 2018 2019 2018 Qualified affordable housing partnerships $32 $29 $65 $59 $34 $31 $69 $63 Other community development investments 20 20 38 38 17 16 32 31 Renewable Energy Partnerships In the second quarter of 2018, the Company began investing in entities that promote renewable energy sources as a limited partner. The carrying value of these renewable energy partnership investments is recorded in Other assets on the Company’s Consolidated Balance Sheets, and the associated tax credits received for these investments are recorded as a reduction to the carrying value of these investments. The Company has determined that these renewable energy tax credit partnerships are VIEs. The Company has concluded that it is not the primary beneficiary of these VIEs because it does not have the power to direct the activities that most significantly impact the VIEs' financial performance and therefore, it is not required to consolidate these VIEs. The Company’s maximum exposure to loss related to these investments is comprised of its equity investments in these partnerships and any additional unfunded equity commitments. Total Return Swaps At June 30, 2019 and December 31, 2018 , the outstanding notional amount of the Company's VIE-facing TRS contracts totaled $2.4 billion and $2.0 billion , and related loans outstanding to VIEs totaled $2.4 billion and $2.0 billion , respectively. These financings were measured at fair value and classified within Trading assets and derivative instruments on the Consolidated Balance Sheets. The Company entered into client-facing TRS contracts of the same outstanding notional amounts. The notional amounts of the TRS contracts with VIEs represent the Company’s maximum exposure to loss, although this exposure has been mitigated via the TRS contracts with clients. For additional information on the Company’s TRS contracts and its involvement with these VIEs, see Note 16 , “Derivative Financial Instruments,” as well as Note 12, "Certain Transfers of Financial Assets and Variable Interest Entities," to the Company's 2018 Annual Report on Form 10-K.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	NOTE 13 - INCOME TAXES For the three months ended June 30, 2019 and 2018 , the provision for income taxes was $105 million and $171 million , representing effective tax rates of 13% and 19% , respectively. For the six months ended June 30, 2019 and 2018 , the provision for income taxes was $208 million and $318 million , representing effective tax rates of 14% and 19% , respectively. The effective tax rates for the six months ended June 30, 2019 and 2018 were favorably impacted by $49 million and $4 million of net discrete income tax benefits, respectively. The $49 million net discrete income tax benefit for the six months ended June 30, 2019 was driven by $31 million of tax benefits related to changes in the liability for unrecognized tax benefits due to the completion of certain income tax authority examinations and the expiration of statutes of limitation, $10 million of tax benefits related primarily to stock-based compensation, and $8 million of tax benefits related primarily to state income tax true-ups. The provision for income taxes includes both federal and state income taxes and differs from the provision using statutory rates due primarily to favorable permanent tax items such as interest income from lending to tax-exempt entities, tax credits, and amortization expense related to qualified affordable housing investment costs. The Company calculated the provision for income taxes by applying the estimated annual effective tax rate to year-to-date pre-tax income and adjusting for discrete items that occurred during the period.

Guarantees

Guarantees	6 Months Ended
	Jun. 30, 2019
Guarantees [Abstract]
Guarantees	NOTE 15 – GUARANTEES The Company has undertaken certain guarantee obligations in the ordinary course of business. The issuance of a guarantee imposes an obligation for the Company to stand ready to perform and make future payments should certain triggering events occur. Payments may be in the form of cash, financial instruments, other assets, shares of stock, or through provision of the Company’s services. The following is a discussion of the guarantees that the Company has issued at June 30, 2019 . The Company has also entered into certain contracts that are similar to guarantees, but that are accounted for as derivative instruments as discussed in Note 16 , “Derivative Financial Instruments.” Letters of Credit Letters of credit are conditional commitments issued by the Company, generally to guarantee the performance of a client to a third party in borrowing arrangements, such as CP , bond financing, or similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to clients but may be reduced by selling participations to third parties. The Company issues letters of credit that are classified as financial standby, performance standby, or commercial letters of credit; however, commercial letters of credit are considered guarantees of funding and are not subject to the disclosure requirements of guarantee obligations. At June 30, 2019 and December 31, 2018 , the maximum potential exposure to loss related to the Company’s issued letters of credit was $2.6 billion and $2.9 billion , respectively. The Company’s outstanding letters of credit generally have a term of more than one year. Some standby letters of credit are designed to be drawn upon in the normal course of business and others are drawn upon only in circumstances of dispute or default in the underlying transaction to which the Company is not a party. In all cases, the Company is entitled to reimbursement from the client. If a letter of credit is drawn upon and reimbursement is not provided by the client, the Company may take possession of the collateral securing the letter of credit, where applicable. The Company monitors its credit exposure under standby letters of credit in the same manner as it monitors other extensions of credit in accordance with its credit policies. Consistent with the methodologies used for all commercial borrowers, an internal assessment of the PD and loss severity in the event of default is performed. The Company’s credit risk management for letters of credit leverages the risk rating process to focus greater visibility on higher risk and higher dollar letters of credit. The allowance associated with letters of credit is a component of the unfunded commitments reserve recorded in Other liabilities on the Consolidated Balance Sheets and is included in the allowance for credit losses as disclosed in Note 7 , “Allowance for Credit Losses.” Additionally, unearned fees relating to letters of credit are recorded in Other liabilities on the Consolidated Balance Sheets. The net carrying amount of unearned fees was immaterial at both June 30, 2019 and December 31, 2018 . Loan Sales and Servicing The Company originates and purchases residential mortgage loans, a portion of which are sold to outside investors in the normal course of business through a combination of whole loan sales to GSE s, Ginnie Mae , and non-agency investors. The Company also originates and sells certain commercial mortgage loans to Fannie Mae and Freddie Mac , originates FHA insured loans, and issues and sells Ginnie Mae commercial MBS secured by FHA insured loans. When loans are sold, representations and warranties regarding certain attributes of the loans are made to third party purchasers. Subsequent to the sale, if a material underwriting deficiency or documentation defect is discovered, the Company may be obligated to repurchase the loan or to reimburse an investor for losses incurred (make whole requests), if such deficiency or defect cannot be cured by the Company within the specified period following discovery. These representations and warranties may extend through the life of the loan. In addition to representations and warranties related to loan sales, the Company makes representations and warranties that it will service the loans in accordance with investor servicing guidelines and standards, which may include (i) collection and remittance of principal and interest, (ii) administration of escrow for taxes and insurance, (iii) advancing principal, interest, taxes, insurance, and collection expenses on delinquent accounts, and (iv) loss mitigation strategies, including loan modifications and foreclosures. The following table summarizes the changes in the Company’s reserve for residential mortgage loan repurchases: Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2019 2018 2019 2018 Balance, beginning of period $24 $39 $26 $39 Repurchase benefit (1 ) (3 ) (3 ) (3 ) Balance, end of period $23 $36 $23 $36 A significant degree of judgment is used to estimate the mortgage repurchase liability as the estimation process is inherently uncertain and subject to imprecision. The Company believes that its reserve appropriately estimates incurred losses based on its current analysis and assumptions. While the mortgage repurchase reserve includes the estimated cost of settling claims related to required repurchases, the Company’s estimate of losses depends on its assumptions regarding GSE and other counterparty behavior, loan performance, home prices, and other factors. The liability is recorded in Other liabilities on the Consolidated Balance Sheets, and the related repurchase (benefit)/provision is recognized in Mortgage-related income in the Consolidated Statements of Income. The following table summarizes the carrying value of the Company’s outstanding repurchased residential mortgage loans: (Dollars in millions) June 30, December 31, 2018 Outstanding repurchased residential mortgage loans: Performing LHFI $140 $183 Nonperforming LHFI 8 16 Total carrying value of outstanding repurchased residential mortgages $148 $199 Residential mortgage loans sold to Ginnie Mae are insured by the FHA or are guaranteed by the VA . As servicer, the Company may elect to repurchase delinquent loans in accordance with Ginnie Mae guidelines; however, the loans continue to be insured. The Company may also indemnify the FHA and VA for losses related to loans not originated in accordance with their guidelines. Commercial Mortgage Loan Loss Share Guarantee In connection with the acquisition of Pillar , the Company assumed a loss share obligation associated with the terms of a master loss sharing agreement with Fannie Mae for multi-family commercial mortgage loans that were sold by Pillar to Fannie Mae under Fannie Mae ’s delegated underwriting and servicing program. Upon the acquisition of Pillar , the Company entered into a lender contract amendment with Fannie Mae for multi-family commercial mortgage loans that Pillar sold to Fannie Mae prior to acquisition and that the Company sold to Fannie Mae subsequent to acquisition, whereby the Company bears a risk of loss of up to one-third of the incurred losses resulting from borrower defaults. The breach of any representation or warranty related to a loan sold to Fannie Mae could increase the Company’s level of risk-sharing associated with the loan. The outstanding UPB of loans sold subject to the loss share guarantee was $3.7 billion and $3.5 billion at June 30, 2019 and December 31, 2018 , respectively. The maximum potential exposure to loss was $1.1 billion and $1.0 billion at June 30, 2019 and December 31, 2018 , respectively. Using probability of default and severity of loss estimates, the Company’s loss share liability was $7 million and $5 million at June 30, 2019 and December 31, 2018 , respectively, and is recorded in Other liabilities on the Consolidated Balance Sheets. Visa The Company executes credit and debit transactions through Visa and Mastercard . The Company is a defendant, along with Visa and Mastercard (the “Card Associations”), as well as other banks, in one of several antitrust lawsuits challenging the practices of the Card Associations (the “Litigation”). The Company entered into judgment and loss sharing agreements with Visa and certain other banks in order to apportion financial responsibilities arising from any potential adverse judgment or negotiated settlements related to the Litigation. Additionally, in connection with Visa ’s restructuring in 2007, shares of Visa common stock were issued to its financial institution members and the Company received its proportionate number of shares of Visa Inc. common stock, which were subsequently converted to Class B shares of Visa Inc. upon completion of Visa ’s IPO in 2008. A provision of the original Visa By-Laws, which was restated in Visa ’s certificate of incorporation, contains a general indemnification provision between a Visa member and Visa that explicitly provides that each member’s indemnification obligation is limited to losses arising from its own conduct and the specifically defined Litigation. While the district court approved a class action settlement of the Litigation in 2012 that settled the claims of both a damages class and an injunctive relief class, the U.S. Court of Appeals for the Second Circuit reversed the district court’s approval of the settlement on June 30, 2016. The U.S. Supreme Court denied plaintiffs’ petition for certiorari on March 27, 2017, and the case returned to the district court for further action. Since being remanded to the district court, plaintiffs have pursued two separate class actions—one class action seeking damages that names, among others, the Company as a defendant, and one class action seeking injunctive relief that does not name the Company as a defendant, but for which the Company could bear some responsibility under the judgment and loss sharing agreement described above. An agreement to resolve the claims was reached and the settlement was preliminarily approved by the district court on January 24, 2019. Agreements associated with Visa ’s IPO have provisions that Visa will fund a litigation escrow account, established for the purpose of funding judgments in, or settlements of, the Litigation. If the escrow account is insufficient to cover the Litigation losses, then Visa will issue additional Class A shares (“loss shares”). The proceeds from the sale of the loss shares would then be deposited in the escrow account. The issuance of the loss shares will cause a dilution of Visa ’s Class B shares as a result of an adjustment to lower the conversion factor of the Class B shares to Class A shares . Visa U.S.A.’s members are responsible for any portion of the settlement or loss on the Litigation after the escrow account is depleted and the value of the Class B shares is fully diluted. In May 2009, the Company sold its 3.2 million Class B shares to the Visa Counterparty and entered into a derivative with the Visa Counterparty . Under the derivative, the Visa Counterparty is compensated by the Company for any decline in the conversion factor as a result of the outcome of the Litigation. Conversely, the Company is compensated by the Visa Counterparty for any increase in the conversion factor. The amount of payments made or received under the derivative is a function of the 3.2 million shares sold to the Visa Counterparty , the change in conversion rate, and Visa ’s share price. The Visa Counterparty , as a result of its ownership of the Class B shares , is impacted by dilutive adjustments to the conversion factor of the Class B shares caused by the Litigation losses. Additionally, the Company will make periodic payments based on the notional of the derivative and a fixed rate until the date on which the Litigation is settled. The fair value of the derivative is estimated based on unobservable inputs consisting of management’s estimate of the probability of certain litigation scenarios and the timing of the resolution of the Litigation. The fair value of the derivative liability was $6 million and $7 million at June 30, 2019 and December 31, 2018 , respectively. The fair value of the derivative is estimated based on the Company’s expectations regarding the resolution of the Litigation. The ultimate impact to the Company could be significantly different based on the Litigation outcome.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	NOTE 16 - DERIVATIVE FINANCIAL INSTRUMENTS The Company enters into various derivative financial instruments, both in a dealer capacity to facilitate client transactions and as an end user as a risk management tool. The Company generally manages the risk associated with these derivatives within the established MRM and credit risk management frameworks. Derivatives may be used by the Company to hedge various economic or client-related exposures. In such instances, derivative positions are typically monitored using a VAR methodology, with exposures reviewed daily. Derivatives are also used as a risk management tool to hedge the Company’s balance sheet exposure to changes in identified cash flow and fair value risks, either economically or in accordance with hedge accounting provisions. The Company’s Corporate Treasury function is responsible for employing the various hedge strategies to manage these objectives. The Company enters into IRLC s on residential and commercial mortgage loans that are accounted for as freestanding derivatives. Additionally, certain contracts containing embedded derivatives are measured, in their entirety, at fair value. All derivatives, including both freestanding and any embedded derivatives that the Company bifurcates from the host contracts, are measured at fair value in the Consolidated Balance Sheets in Trading assets and derivative instruments and Trading liabilities and derivative instruments. The associated gains and losses are either recognized in AOCI, net of tax, or within the Consolidated Statements of Income, depending upon the use and designation of the derivatives. Credit and Market Risk Associated with Derivative Instruments Derivatives expose the Company to risk that the counterparty to the derivative contract does not perform as expected. The Company manages its exposure to counterparty credit risk associated with derivatives by entering into transactions with counterparties with defined exposure limits based on their credit quality and in accordance with established policies and procedures. All counterparties are reviewed regularly as part of the Company’s credit risk management practices and appropriate action is taken to adjust the exposure limits to certain counterparties as necessary. The Company’s derivative transactions are generally governed by ISDA agreements or other legally enforceable industry standard master netting agreements. In certain cases and depending on the nature of the underlying derivative transactions, bilateral collateral agreements are also utilized. Furthermore, the Company and its subsidiaries are subject to OTC derivative clearing requirements, which require certain derivatives to be cleared through central clearing houses, such as LCH and the CME . These clearing houses require the Company to post initial and variation margin to mitigate the risk of non-payment, the latter of which is received or paid daily based on the net asset or liability position of the contracts. Effective January 3, 2017, the CME amended its rulebook to legally characterize variation margin cash payments for cleared OTC derivatives as settlement rather than as collateral. Consistent with the CME 's amended requirements, LCH amended its rulebook effective January 16, 2018, to legally characterize variation margin cash payments for cleared OTC derivatives as settlement rather than as collateral. As a result, in the first quarter of 2018, the Company began reducing the corresponding derivative asset and liability balances for LCH -cleared OTC derivatives to reflect the settlement of those positions via the exchange of variation margin. When the Company has more than one outstanding derivative transaction with a single counterparty, and there exists a legal right of offset with that counterparty, the Company considers its exposure to the counterparty to be the net fair value of its derivative positions with that counterparty. If the net fair value is positive, then the corresponding asset value also reflects cash collateral held. At June 30, 2019 , the economic exposure of these net derivative asset positions was $1.1 billion , reflecting $1.5 billion of net derivative gains, adjusted for cash and other collateral of $342 million that the Company held in relation to these positions. At December 31, 2018 , the economic exposure of net derivative asset positions was $541 million , reflecting $891 million of net derivative gains, adjusted for cash and other collateral held of $350 million . Derivatives also expose the Company to market risk arising from the adverse effects that changes in market factors, such as interest rates, currency rates, equity prices, commodity prices, or implied volatility, may have on the value of the Company's derivatives. The Company manages this risk by establishing and monitoring limits on the types and degree of risk that may be undertaken. The Company measures its market risk exposure using a VAR methodology for derivatives designated as trading instruments. Other tools and risk measures are also used to actively manage risk associated with derivatives including scenario analysis and stress testing. Derivative instruments are priced using observable market inputs at a mid-market valuation point and take into consideration appropriate valuation adjustments for collateral, market liquidity, and counterparty credit risk. For purposes of determining fair value adjustments to its OTC derivative positions, the Company takes into consideration the credit profile and likelihood of default by counterparties, the CVA , the Company’s own credit risk, the DVA , as well as the Company's net exposure, which considers legally enforceable master netting agreements and collateral along with remaining maturities. In determining the CVA , the expected loss of each counterparty is estimated using market-based views of counterparty default probabilities observed in the single-name CDS market, when available and of sufficient liquidity. When single-name CDS market data is not available or not of sufficient liquidity, the probability of default is estimated using a combination of the Company’s internal risk rating system and sector/rating based CDS data. For purposes of estimating the Company’s own credit risk on derivative liability positions, the DVA , the Company uses probabilities of default from observable, sector/rating based CDS data. For additional information on the Company’s fair value measurements, see Note 17 , “Fair Value Election and Measurement.” Currently, the industry standard master netting agreements governing the majority of the Company's derivative transactions with counterparties contain bilateral events of default and acceleration provisions related to the creditworthiness of the Bank and the counterparty. Should the Bank or a counterparty default under any of these provisions, the other party would be permitted to close out the transactions on a net basis, at amounts that would approximate the fair values of the derivatives, resulting in a single sum due by one party to the other. The counterparties would have the right to apply any collateral posted by the Bank against any net amount owed by the Bank. Additionally, certain of the Company’s derivative liability positions, totaling $1.2 billion and $589 million in fair value at June 30, 2019 and December 31, 2018 , respectively, contain provisions conditioned on downgrades of the Bank’s credit rating. These provisions, if triggered, would either give rise to an ATE that permits the counterparties to close-out net and apply collateral or, where a CSA is present, require the Bank to post additional collateral. At June 30, 2019 , the Bank held senior long-term debt credit ratings of Baal / A- / A- from Moody’s , S&P , and Fitch , respectively. At June 30, 2019 , ATE s have been triggered for less than $1 million in fair value liabilities. The maximum additional liability that could be triggered from ATE s was approximately $13 million at June 30, 2019 . At June 30, 2019 , $1.2 billion in fair value of derivative liabilities were subject to CSA s, against which the Bank has posted $862 million in collateral, primarily in the form of cash. Pursuant to the terms of the CSA , the Bank would not be required to post any additional collateral against these contracts if the Bank were downgraded to Baa2/BBB+. Further downgrades to Baa3/BBB and Ba1/BBB- would require the Bank to post an additional $2 million and $11 million of collateral, respectively. Any downgrades below Ba2/BB+ do not contain predetermined collateral posting levels.

These notional amounts are calculated as the notional of the derivative participated adjusted by the relevant RWA conversion factor. 8 Notional amounts include $41 million related to the Visa derivative liability at both June 30, 2019 and December 31, 2018 . See Note 15 , "Gua rantees" for additional information. Netting of Derivative Instruments The Company has various financial assets and financial liabilities that are subject to enforceable master netting agreements or similar agreements. The Company's securities borrowed or purchased under agreements to resell, and securities sold under agreements to repurchase, that are subject to enforceable master netting agreements or similar agreements, are discussed in Note 3 , “Federal Funds Sold and Securities Financing Activities.” The Company enters into ISDA or other legally enforceable industry standard master netting agreements with derivative counterparties. Under the terms of the master netting agreements, all transactions between the Company and the counterparty constitute a single business relationship such that in the event of default, the nondefaulting party is entitled to set off claims and apply property held by that party in respect of any transaction against obligations owed. The following tables present total gross derivative instrument assets and liabilities at June 30, 2019 and December 31, 2018 , which are adjusted to reflect the effects of legally enforceable master netting agreements and cash collateral received or paid when calculating the net amount reported in the Consolidated Balance Sheets. Also included in the tables are financial instrument collateral related to legally enforceable master netting agreements that represents securities collateral received or pledged and customer cash collateral held at third party custodians. These amounts are not offset on the Consolidated Balance Sheets but are shown as a reduction to total derivative instrument assets and liabilities to derive net derivative assets and liabilities. These amounts are limited to the derivative asset/liability balance, and accordingly, do not include excess collateral received/pledged.

At December 31, 2018 , $639 million , net of $338 million offsetting cash collateral, is recognized in Trading assets and derivative instruments within the Company's Consolidated Balance Sheets. 2 At June 30, 2019 , $206 million , net of $918 million offsetting cash collateral, is recognized in Trading liabilities and derivative instruments within the Company's Consolidated Balance Sheets. At December 31, 2018 , $410 million , net of $652 million offsetting cash collateral, is recognized in Trading liabilities and derivative instruments within the Company's Consolidated Balance Sheets. Fair Value and Cash Flow Hedging Instruments Fair Value Hedging The Company enters into interest rate swap agreements as part of its risk management objectives for hedging exposure to changes in fair value due to changes in interest rates. These hedging arrangements convert certain fixed rate long-term debt and CD s to floating rates. For all designated fair value hedge relationships, changes in the fair value of the hedging instrument attributable to the hedged risk are recognized in the same income statement line as the earnings impact from the hedged item. There were no components of derivative gains or losses excluded in the Company’s assessment of hedge effectiveness related to the fair value hedges. Cash Flow Hedging The Company utilizes a comprehensive risk management strategy to monitor sensitivity of earnings to movements in interest rates. Specific types of funding and principal amounts hedged are determined based on prevailing market conditions and the shape of the yield curve. In conjunction with this strategy, the Company may employ various interest rate derivatives as risk management tools to hedge interest rate risk from recognized assets and liabilities or from forecasted transactions. The terms and notional amounts of derivatives are determined based on management’s assessment of future interest rates, as well as other factors. The Company enters into interest rate swaps designated as cash flow hedging instruments to hedge its exposure to contractually specified interest rate risk associated with floating rate loans. For the three and six months ended June 30, 2019 , the amount of pre-tax gain recognized in OCI on derivative instruments was $143 million and $204 million , respectively. For the three and six months ended June 30, 2018 , the amount of pre-tax loss recognized in OCI on derivative instruments was $61 million and $225 million , respectively. At June 30, 2019 , the maturities for hedges of floating rate loans ranged from less than one year to seven years , with the weighted average being 2.8 years . At December 31, 2018 , the maturities for hedges of floating rate loans ranged from less than one year to five years , with the weighted average being 2.5 years . These hedges have been highly effective in offsetting the designated risks. At June 30, 2019 , $186 million of deferred net pre-tax losses on derivative instruments designated as cash flow hedges on floating rate loans recognized in AOCI are expected to be reclassified into net interest income during the next twelve months. The amount to be reclassified into income incorporates the impact from both active and terminated cash flow hedges, including the net interest income earned on the active hedges, assuming no changes in LIBOR . The Company may choose to terminate or de-designate a hedging relationship due to a change in the risk management objective for that specific hedge item, which may arise in conjunction with an overall balance sheet management strategy. The following table presents gains and losses on derivatives in fair value and cash flow hedging relationships by contract type and by income statement line item. The table does not disclose the financial impact of the activities that these derivative instruments are intended to hedge.

The primary risks that the Company economically hedges are interest rate risk, foreign exchange risk, and credit risk. The Company mitigates these risks by entering into offsetting derivatives either on an individual basis or collectively on a macro basis. The Company utilizes interest rate derivatives as economic hedges related to: • Residential MSRs . The Company hedges these instruments with a combination of interest rate derivatives, including forward and option contracts, futures, and forward rate agreements. • Residential mortgage IRLC s and LHFS . The Company hedges these instruments using forward and option contracts, futures, and forward rate agreements. The Company is exposed to volatility and changes in foreign exchange rates associated with certain commercial loans. To hedge against this foreign exchange rate risk, the Company enters into foreign exchange rate contracts that provide for the future receipt and delivery of foreign currency at previously agreed-upon terms. The Company enters into CDS to hedge credit risk associated with certain loans held within its Wholesale segment. The Company accounts for these contracts as derivatives, and accordingly, recognizes these contracts at fair value, with changes in fair value recognized in Other noninterest income in the Consolidated Statements of Income. Trading activity primarily includes interest rate swaps, equity derivatives, CDS , futures, options, foreign exchange rate contracts, and commodity derivatives. These derivatives are entered into in a dealer capacity to facilitate client transactions, or are utilized as a risk management tool by the Company as an end user (predominantly in certain macro-hedging strategies). The impacts of derivative instruments used for economic hedging or trading purposes on the Consolidated Statements of Income are presented in the following table: Classification of Gain/(Loss) Recognized in Income on Derivatives Amount of Gain/(Loss) Recognized in Income on Derivatives During the Three Months Ended June 30 Amount of Gain/(Loss) Recognized in Income on Derivatives During the Six Months Ended June 30 (Dollars in millions) 2019 2018 2019 2018 Derivative instruments not designated as hedging instruments: Interest rate contracts hedging: Residential MSRs Mortgage-related income $156 ($37 ) $270 ($157 ) LHFS, IRLCs Mortgage-related income (26 ) 1 (45 ) 48 LHFI Other noninterest income (2 ) 1 (3 ) 3 Trading activity Trading income 20 21 34 30 Foreign exchange rate contracts hedging loans and trading activity Trading income (4 ) 42 (6 ) 40 Credit contracts hedging: LHFI Other noninterest income (5 ) (1 ) (15 ) (1 ) Trading activity Trading income 7 5 13 11 Equity contracts hedging trading activity Trading income 10 1 28 2 Other contracts: IRLCs and other Mortgage-related income; 53 26 86 20 Commodity derivatives Trading income 1 — 1 — Total $210 $59 $363 ($4 ) Credit Derivative Instruments As part of the Company's trading businesses, the Company enters into contracts that are, in form or substance, written guarantees; specifically, CDS , risk participations, and TRS . The Company accounts for these contracts as derivatives, and accordingly, records these contracts at fair value, with changes in fair value recognized in Trading income in the Consolidated Statements of Income. The Company has also entered into TRS contracts on loans. The Company’s TRS business consists of matched trades, such that when the Company pays depreciation on one TRS , it receives the same amount on the matched TRS . To mitigate its credit risk, the Company typically receives initial cash collateral from the counterparty upon entering into the TRS and is entitled to additional collateral if the fair value of the underlying reference assets deteriorates. The following table presents information related to the Company's outstanding TRS contracts. (Dollars in millions) June 30, 2019 December 31, 2018 Outstanding TRS notional balances $2,392 $2,009 TRS assets at fair value 37 97 TRS liabilities at fair value 33 94 Cash collateral held for TRS contracts 643 601 For additional information on the Company’s TRS contracts, see Note 11 , “Certain Transfers of Financial Assets and Variable Interest Entities,” to the Consolidated Financial Statements in this Form 10-Q , as well as Note 20, “Fair Value Election and Measurement,” to the Company’s 2018 Annual Report on Form 10-K. The Company writes risk participations, which are credit derivatives, whereby the Company has guaranteed payment to a dealer counterparty in the event the counterparty experiences a loss on a derivative, such as an interest rate swap, due to a failure to pay by the counterparty’s customer (the “obligor”) on that derivative. The Company manages its payment risk on its risk participations by monitoring the creditworthiness of the obligors, which are all corporations or partnerships, through the normal credit review process that the Company would have performed had it entered into a derivative directly with the obligors. To date, no material losses have been incurred related to the Company’s written risk participations. At June 30, 2019 , the remaining terms on these risk participations generally ranged from less than one year to 11 years , with a weighted average term on the maximum estimated exposure of 6.1 years . At December 31, 2018 , the remaining terms on these risk participations generally ranged from less than one year to 10 years , with a weighted average term on the maximum estimated exposure of 5.9 years . The Company’s maximum estimated exposure to written risk participations, as measured by projecting a maximum value of the guaranteed derivative instruments based on interest rate curve simulations and assuming 100% default by all obligors on the maximum values, was approximately $273 million and $217 million at June 30, 2019 and December 31, 2018 , respectively. The fair values of the written risk participations were immaterial at both June 30, 2019 and December 31, 2018 .

Fair Value Disclosures [Abstract]
Fair Value Election and Measurement	NOTE 17 - FAIR VALUE ELECTION AND MEASUREMENT The Company measures certain assets and liabilities at fair value, which are classified as level 1, 2, or 3 within the fair value hierarchy, as shown below, on the basis of whether the measurement employs observable or unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s own assumptions, taking into account information about market participant assumptions that is readily available. • Level 1: Quoted prices for identical instruments in active markets • Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets • Level 3: Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable Fair value is defined as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. The Company’s recurring fair value measurements are based on either a requirement to measure such assets and liabilities at fair value or on the Company’s election to measure certain financial assets and liabilities at fair value. Assets and liabilities that are required to be measured at fair value on a recurring basis include trading securities, derivative instruments, securities AFS, and certain other equity securities. Assets and liabilities that the Company has elected to measure at fair value on a recurring basis include trading loans, certain LHFS and LHFI, residential MSRs, brokered time deposits, and certain structured notes and fixed rate issuances included in long-term debt. The Company elects to measure certain assets and liabilities at fair value to better align its financial performance with the economic value of actively traded or hedged assets or liabilities. The use of fair value also enables the Company to mitigate non-economic earnings volatility caused from financial assets and liabilities being measured using different bases of accounting, as well as to more accurately portray the active and dynamic management of the Company’s balance sheet. The Company uses various valuation techniques and assumptions in estimating fair value. The assumptions used to estimate the value of an instrument have varying degrees of impact to the overall fair value of an asset or liability. This process involves gathering multiple sources of information, including broker quotes, values provided by pricing services, trading activity in other identical or similar securities, market indices, and pricing matrices. When observable market prices for the asset or liability are not available, the Company employs various modeling techniques, such as discounted cash flow analyses, to estimate fair value. Models used to produce material financial reporting information are validated prior to use and following any material change in methodology. Their performance is monitored at least quarterly, and any material deterioration in model performance is escalated. The Company has formal processes and controls in place to support the appropriateness of its fair value estimates. For fair values obtained from a third party, or those that include certain trader estimates of fair value, there is an independent price validation function that provides oversight for these estimates. For level 2 instruments and certain level 3 instruments, the validation generally involves evaluating pricing received from two or more third party pricing sources that are widely used by market participants. The Company evaluates this pricing information from both a qualitative and quantitative perspective and determines whether any pricing differences exceed acceptable thresholds. If thresholds are exceeded, the Company assesses differences in valuation approaches used, which may include contacting a pricing service to gain further insight into the valuation of a particular security or class of securities to resolve the pricing variance, which could include an adjustment to the price used for financial reporting purposes. The Company classifies instruments within level 2 in the fair value hierarchy when it determines that external pricing sources estimated fair value using prices for similar instruments trading in active markets. A wide range of quoted values from pricing sources may imply a reduced level of market activity and indicate that significant adjustments to price indications have been made. In such cases, the Company evaluates whether the asset or liability should be classified as level 3. Determining whether to classify an instrument as level 3 involves judgment and is based on a variety of subjective factors, including whether a market is inactive. A market is considered inactive if significant decreases in the volume and level of activity for the asset or liability have been observed. Recurring Fair Value Measurements The following tables present certain information regarding assets and liabilities measured at fair value on a recurring basis and the changes in fair value for those specific financial instruments for which fair value has been elected. For a discussion of the valuation techniques and inputs used in estimating fair value for assets and liabilities measured at fair value on a recurring basis, see Note 20, “Fair Value Election and Measurement,” to the Company's 2018 Annual Report on Form 10-K .

Non-recurring Fair Value Measurements The following tables present gains and losses recognized on assets still held at period end, and measured at fair value on a non-recurring basis, for the three and six months ended June 30, 2019 and the year ended December 31, 2018 . Adjustments to fair value generally result from the application of LOCOM , or the measurement alternative, or through write-downs of individual assets. The tables do not reflect changes in fair value attributable to economic hedges the Company may have used to mitigate interest rate risk associated with LHFS. Fair Value Measurements Losses for the Losses for the Six Months Ended June 30, 2019 (Dollars in millions) June 30, 2019 Level 1 Level 2 Level 3 LHFS $17 $— $17 $— $— ($1 ) LHFI 86 — — 86 — — OREO 23 — — 23 (2 ) (4 ) Other assets 17 — 4 13 (2 ) (3 ) Fair Value Measurements (Losses)/Gains for the December 31, 2018 (Dollars in millions) December 31, 2018 Level 1 Level 2 Level 3 LHFS $47 $— $47 $— ($1 ) LHFI 63 — — 63 — OREO 19 — — 19 (4 ) Other assets 67 — 47 20 24 Discussed below are the valuation techniques and inputs used in estimating fair values for assets measured at fair value on a non-recurring basis and classified as level 2 and/or 3. Loans Held for Sale At June 30, 2019 and December 31, 2018 , LHFS classified as level 2 consisted of commercial loans that were valued using market prices and measured at LOCOM . No impairment charges were recognized during the three months ended June 30, 2019 attributable to changes in the fair value of LHFS. During the six months ended June 30, 2019 and the year ended December 31, 2018 , the Company recognized an immaterial amount of impairment charges attributable to changes in the fair value of LHFS. Loans Held for Investment At June 30, 2019 and December 31, 2018 , LHFI classified as level 3 consisted primarily of consumer loans discharged in Chapter 7 bankruptcy that had not been reaffirmed by the borrower. Cash proceeds from the sale of the underlying collateral is the expected source of repayment for a majority of these loans. Accordingly, the fair value of these loans is derived from the estimated fair value of the underlying collateral, incorporating market data if available. Due to the lack of market data for similar assets, all of these loans are classified as level 3. There were no gains/(losses) recognized during the three and six months ended June 30, 2019 or during the year ended December 31, 2018 , as the charge-offs related to these loans are a component of the ALLL. OREO OREO is measured at the lower of cost or fair value less costs to sell. Level 3 OREO consists primarily of residential homes, commercial properties, and vacant lots and land for which initial valuations are based on property-specific appraisals, broker pricing opinions, or other limited, highly subjective market information. Updated value estimates are received regularly for level 3 OREO . Other Assets Other assets consist of equity investments, other repossessed assets, assets under operating leases where the Company is the lessor, branch properties, and land held for sale. The Company elected the measurement alternative for measuring certain equity securities without readily determinable fair values, which are adjusted based on any observable price changes in orderly transactions. These equity securities are classified as level 2 based on the valuation methodology and associated inputs. There were no remeasurement gains/(losses) recognized during the three and six months ended June 30, 2019 on these equity securities. During the year ended December 31, 2018 , the Company recognized remeasurement gains of $30 million on these equity securities. Other repossessed assets include repossessed personal property that is measured at fair value less cost to sell. These assets are classified as level 3 as their fair value is determined based on a variety of subjective, unobservable factors. There were no losses recognized in earnings by the Company on other repossessed assets during the three and six months ended June 30, 2019 or during the year ended December 31, 2018 , as the impairment charges on repossessed personal property were a component of the ALLL. The Company monitors the fair value of assets under operating leases where the Company is the lessor and recognizes impairment on the leased asset to the extent the carrying value is not recoverable and is greater than its fair value. Fair value is determined using collateral specific pricing digests, external appraisals, broker opinions, recent sales data from industry equipment dealers, and the discounted cash flows derived from the underlying lease agreement. As market data for similar assets and lease arrangements is available and used in the valuation, these assets are considered level 2. During the three and six months ended June 30, 2019 and the year ended December 31, 2018 , the Company recognized an immaterial amount of impairment charges attributable to changes in the fair value of various personal property under operating leases. Branch properties are classified as level 3, as their fair value is based on property-specific appraisals and broker opinions. The Company recognized an immaterial amount of impairment charges on branch properties during the three and six months ended June 30, 2019 . During the year ended December 31, 2018 , the Company recognized impairment charges of $5 million on branch properties. Land held for sale is recorded at the lesser of carrying value or fair value less cost to sell, and is considered level 3 as its fair value is determined based on property-specific appraisals and broker opinions.

At June 30, 2019 and December 31, 2018 , the Company had $75.9 billion and $72.0 billion of unfunded commercial loan commitments and letters of credit, respectively, that are not included in the preceding tables. Since no active trading market exists for these instruments, a reasonable estimate of the instruments' fair value is the carrying value of deferred fees plus the related unfunded commitments reserve, which totaled $73 million and $72 million at June 30, 2019 and December 31, 2018 , respectively. The Company does not estimate the fair value of its unfunded consumer lending commitments, which can generally be canceled by providing notice to the borrower.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	NOTE 18 – CONTINGENCIES Litigation and Regulatory Matters In the ordinary course of business, the Company and its subsidiaries are parties to numerous civil claims and lawsuits and subject to regulatory examinations, investigations, and requests for information. Some of these matters involve claims for substantial amounts. The Company’s experience has shown that the damages alleged by plaintiffs or claimants are often overstated, based on unsubstantiated legal theories, unsupported by facts, and/or bear no relation to the ultimate award that a court might grant. Additionally, the outcome of litigation and regulatory matters and the timing of ultimate resolution are inherently difficult to predict. These factors make it difficult for the Company to provide a meaningful estimate of the range of reasonably possible outcomes of claims in the aggregate or by individual claim. However, on a case-by-case basis, reserves are established for those legal claims in which it is probable that a loss will be incurred and the amount of such loss can be reasonably estimated. The Company's financial statements at June 30, 2019 reflect the Company's current best estimate of probable losses associated with these matters, including costs to comply with various settlement agreements, where applicable. The actual costs of resolving these claims may be substantially higher or lower than the amounts reserved. For a limited number of legal matters in which the Company is involved, the Company is able to estimate a range of reasonably possible losses in excess of related reserves, if any. Management currently estimates these losses to range from $0 to approximately $150 million . This estimated range of reasonably possible losses represents the estimated possible losses over the life of such legal matters, which may span a currently indeterminable number of years, and is based on information available at June 30, 2019 . The matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those matters for which an estimate is not possible are not included within this estimated range; therefore, this estimated range does not represent the Company’s maximum loss exposure. Based on current knowledge, it is the opinion of management that liabilities arising from legal claims in excess of the amounts currently reserved, if any, will not have a material impact on the Company’s financial condition, results of operations, or cash flows. However, in light of the significant uncertainties involved in these matters and the large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to the Company’s financial condition, results of operations, or cash flows for any given reporting period. The following is a description of certain litigation and regulatory matters: Card Association Antitrust Litigation The Company is a defendant, along with Visa and Mastercard , as well as several other banks, in several antitrust lawsuits challenging their practices. For a discussion regarding the Company’s involvement in this litigation matter, see Note 15 , “Guarantees.” Bickerstaff v. SunTrust Bank This case was filed in the Fulton County State Court on July 12, 2010, and an amended complaint was filed on August 9, 2010. Plaintiff asserts that all overdraft fees charged to his account which related to debit card and ATM transactions are actually interest charges and therefore subject to the usury laws of Georgia. Plaintiff has brought claims for violations of civil and criminal usury laws, conversion, and money had and received, and purports to bring the action on behalf of all Georgia citizens who incurred such overdraft fees within the four years before the complaint was filed where the overdraft fee resulted in an interest rate being charged in excess of the usury rate. On April 8, 2013, the plaintiff filed a motion for class certification and that motion was denied but the ruling was later reversed and remanded by the Georgia Supreme Court. On October 6, 2017, the trial court granted plaintiff's motion for class certification and the decision was affirmed by the Georgia Court of Appeals on March 6, 2019. The Bank filed a petition with the Georgia Supreme Court on April 15, 2019, asking the court to review the decision. Mutual Funds ERISA Class Action On March 11, 2011, the Company and certain officers, directors, and employees of the Company were named in a putative class action alleging that they breached their fiduciary duties under ERISA by offering certain STI Classic Mutual Funds as investment options in the Plan. The plaintiffs purport to represent all current and former Plan participants who held the STI Classic Mutual Funds in their Plan accounts from April 2002 through December 2010 and seek to recover alleged losses these Plan participants supposedly incurred as a result of their investment in the STI Classic Mutual Funds. This action is pending in the U.S. District Court for the Northern District of Georgia, Atlanta Division (the “District Court”). Subsequently, plaintiffs' counsel initiated a substantially similar lawsuit against the Company naming two new plaintiffs. On June 27, 2014, Brown, et al. v. SunTrust Banks, Inc., et al., another putative class action alleging breach of fiduciary duties associated with the inclusion of STI Classic Mutual Funds as investment options in the Plan, was filed in the U.S. District Court for the District of Columbia but then was transferred to the District Court. After various appeals, the cases were remanded to the District Court. On March 25, 2016, a consolidated amended complaint was filed, consolidating all of these pending actions into one case . The Company filed an answer to the consolidated amended complaint on June 6, 2016. Subsequent to the closing of fact discovery, plaintiffs filed their second amended consolidated complaint on December 19, 2017 which among other things named five new defendants. On January 2, 2018, defendants filed their answer to the second amended consolidated complaint. Defendants' motion for partial summary judgment was filed on January 12, 2018, and on January 16, 2018 the plaintiffs filed for motion for class certification. Defendants' motion for partial summary judgment was granted by the District Court on May 2, 2018, which held that all claims prior to March 11, 2005 have been dismissed as well as dismissing three individual defendants from action. On June 27, 2018, the District Court granted the plaintiffs' motion for class certification. On March 29, 2019, the District Court dismissed RidgeWorth Capital Management, Inc. from the lawsuit and on July 16, 2019, the District Court dismissed plaintiffs' claim for successor liability. A motion for summary judgment seeking dismissal of the remaining claims has been filed by the defendants and is pending. Millennium Lender Claim Trust v. STRH and SunTrust Bank, et al. In August 2017, the Trustee of the Millennium Lender Claim Trust filed a suit in the New York State Court against STRH , the Bank, and other lenders of the $1.775 B Millennium Health LLC f/k/a Millennium Laboratories LLC (“Millennium”) syndicated loan. The Trustee alleges that the loan was actually a security and that defendants misrepresented or omitted to state material facts in the offering materials and communications provided concerning the legality of Millennium's sales, marketing, and billing practices and the known risks posed by a pending government investigation into the illegality of such practices. The Trustee brings claims for violation of the California Corporate Securities Law, the Massachusetts Uniform Securities Act, the Colorado Securities Act, and the Illinois Securities Law, as well as negligent misrepresentation and seeks rescission of sales of securities as well as unspecified rescissory damages, compensatory damages, punitive damages, interest, and attorneys' fees and costs. The defendants removed the case to the U.S. District Court for the Southern District of New York and Trustee's motion to remand the case back to state court was denied. The defendants filed a motion to dismiss the claims on April 12, 2019. SunTrust and BB&T Merger Litigation Following the Merger announcement, six civil actions were filed challenging, among other things, the adequacy of the disclosures contained in the preliminary proxy statement/prospectus filed by BB&T with the SEC in connection with the proposed transaction. Five of these suits were filed by purported SunTrust stockholders against SunTrust and its Board and assert claims under Sections 14(a) and 20(a) of the Exchange Act challenging the adequacy of the public disclosures made concerning the proposed transaction. One of these five suits also asserts a claim against BB&T under Section 20(a). The sixth suit was filed by a purported BB&T stockholder against BB&T and its board of directors and asserts claims under state law challenging, among other things, the adequacy of the public disclosures made concerning the proposed transaction. Following discussions, SunTrust and BB&T reached agreement with plaintiffs to resolve these actions by making certain supplemental disclosures in the joint proxy statement/prospectus filed with the SEC in connection with the proposed transaction, which became definitive on June 19, 2019. To date, one of the suits filed by purported SunTrust stockholders has been dismissed with prejudice, and the suit filed by a purported BB&T stockholder has been discontinued with prejudice. Plaintiffs in the four remaining suits have similarly agreed to dismiss their actions in their entirety, with prejudice as to the named plaintiffs only and without prejudice to all other members of the putative class.

Segment Reporting [Abstract]
Business Segment Reporting	NOTE 19 - BUSINESS SEGMENT REPORTING The Company operates and measures business activity across two segments: Consumer and Wholesale , with functional activities included in Corporate Other . The Company's business segment structure is based on the manner in which financial information is evaluated by management as well as the products and services provided or the type of client served. The following is a description of the segments and their primary businesses at June 30, 2019 . The Consumer segment is made up of three primary businesses: • Consumer Banking provides services to individual consumers and business banking clients through an extensive network of traditional and in-store branches, ATM s, online banking ( www.suntrust.com ), mobile banking, and by telephone (1-800-SUNTRUST). Financial products and services offered to consumers and small business clients include deposits and payments, loans, and various fee-based services. Consumer Banking also serves as an entry point for clients and provides services for other businesses. • Consumer Lending Solutions offers an array of lending products to individual consumers and business banking clients via the Company's Consumer Banking and PWM businesses, correspondent channels, the internet ( www.suntrust.com and www.lightstream.com ), telephone (1-800-SUNTRUST), as well as through various national offices and partnerships. Products offered include mortgages, home equity lines, personal credit lines and loans, direct auto, indirect auto, student lending, credit cards, and other lending products. Mortgage products are either sold in the secondary market, generally with servicing rights retained, or held in the Company’s LHFI portfolio. Consumer Lending Solutions also services mortgage loans for other investors in addition to loans held in the Company’s LHFI portfolio. • PWM provides a full array of wealth management products and professional services to individual consumers and institutional clients, including loans, deposits, brokerage, professional investment advisory, and trust services to clients seeking active management of their financial resources. Institutional clients are served by the Institutional Investment Solutions business. Discount/online and full-service brokerage products are offered to individual clients through STIS . Investment advisory products and services are offered to clients by STAS , an SEC registered investment advisor. PWM also includes GFO Advisory Services, LLC, which provides family office solutions to clients and their families to help them manage and sustain wealth across multiple generations, including family meeting facilitation, consolidated reporting, expense management, specialty asset management, and business transition advice, as well as other wealth management disciplines. The Wholesale segment is made up of three primary businesses and the Treasury & Payment Solutions product group: • CIB delivers comprehensive capital markets solutions, including advisory, capital-raising, and financial risk management, with the goal of serving the needs of both public and private companies in the Wholesale segment and PWM business. Investment Banking and Corporate Banking teams within CIB serve clients across the nation, offering a full suite of traditional banking and investment banking products and services to companies with annual revenues typically greater than $150 million. Investment Banking serves select industry segments including consumer and retail, energy, technology, financial services, healthcare, industrials, and media and communications. Corporate Banking serves clients across diversified industry sectors based on size, complexity, and frequency of capital markets issuance. CIB also includes the Company's Asset Finance Group , which offers a full complement of asset-based financing solutions such as securitizations, asset-based lending, equipment financing, and structured real estate arrangements. • Commercial Banking offers an array of traditional banking products, including lending, cash management, and investment banking solutions via CIB , to commercial clients (generally clients with revenues between $5 million and $250 million), including not-for-profit organizations, governmental entities, healthcare and aging services , and auto dealer financing (floor plan inventory financing). Local teams deliver these solutions along with the Company's industry expertise to commercial clients to help them achieve smart growth. • Commercial Real Estate provides a range of credit and deposit services as well as fee-based product offerings on a regional delivery basis to privately held developers, operators, and investors in commercial real estate properties through its National Banking Division.

Real Estate Corporate and Investment Banking targets relationships with REIT s and homebuilders, both publicly-traded and privately owned. The Investor Services Group offers loan administration, special servicing, valuation, and advisory services to third party clients. • Treasury & Payment Solutions provides business clients in the Wholesale segment with services required to manage their payments and receipts, combined with the ability to manage and optimize their deposits across all aspects of their business. Treasury & Payment Solutions operates all electronic and paper payment types, including card, wire transfer, ACH , check, and cash. It also provides clients the means to manage their accounts electronically online, both domestically and internationally. Corporate Other includes management of the Company’s investment securities portfolio, long-term debt, end user derivative instruments, short-term liquidity and funding activities, balance sheet risk management, and most real estate assets, as well as the Company's functional activities such as marketing, finance, enterprise risk, legal, enterprise information services, and executive management, among others. Because business segment results are presented based on management accounting practices, the transition to the consolidated results prepared under U.S. GAAP creates certain differences, which are reflected in reconciling items. Business segment reporting conventions are described below. • Net interest income-FTE – is reconciled from Net interest income and is grossed-up on an FTE basis to make income from tax-exempt assets comparable to other taxable products. Segment results reflect matched maturity funds transfer pricing, which ascribes credits or charges based on the economic value or cost created by assets and liabilities of each segment. Differences between these credits and charges are captured as reconciling items. • Provision for credit losses – represents net charge-offs by segment combined with an allocation to the segments for the provision attributable to each segment's quarterly change in the ALLL and unfunded commitments reserve balances. • Noninterest income – includes federal and state tax credits that are grossed-up on a pre-tax equivalent basis, related primarily to certain community development investments. • Provision for income taxes-FTE – is calculated using a blended income tax rate for each segment and includes reversals of the tax adjustments and credits described above. The difference between the calculated provision for income taxes at the segment level and the consolidated provision for income taxes is reported as reconciling items. The segment’s financial performance is comprised of direct financial results and allocations for various corporate functions that provide management an enhanced view of the segment’s financial performance. Internal allocations include the following: • Operational costs – expenses are charged to segments based on an activity-based costing process, which also allocates residual expenses to the segments. Generally, recoveries of these costs are reported in Corporate Other. • Support and overhead costs – expenses not directly attributable to a specific segment are allocated based on various drivers (number of equivalent employees, number of PCs/laptops, net revenue, etc.). Recoveries for these allocations are reported in Corporate Other. The application and development of management reporting methodologies is an active process and undergoes periodic enhancements. The implementation of these enhancements to the internal management reporting methodology may materially affect the results disclosed for each segment, with no impact on consolidated results. If significant changes to management reporting methodologies take place, the impact of these changes is quantified and prior period information is revised, when practicable.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Accounting Policies Recently Adopted and Pending Accounting Pronouncements	Accounting Pronouncements The following table summarizes ASU s issued by the FASB that were adopted during the six months ended June 30, 2019 or not yet adopted as of June 30, 2019 , that could have a material effect on the Company’s financial statements: Standard Description Required Date of Adoption Effect on the Financial Statements or Other Significant Matters Standards Adopted in 2019 ASU 2016-02, Leases (Topic 842) and subsequent related ASUs These ASUs create and amend ASC Topic 842, Leases , which supersedes ASC Topic 840, Leases . ASC Topic 842 requires lessees to recognize right-of-use assets and associated liabilities that arise from leases, with the exception of short-term leases. These ASUs do not make significant changes to lessor accounting; however, there were certain improvements made to align lessor accounting with the lessee accounting model and ASC Topic 606, Revenue from Contracts with Customers . Furthermore, there are several new qualitative and quantitative disclosures required for lessees and lessors, including updated guidance around the presentation of certain cash receipts on the Company’s Consolidated Statements of Cash Flows. January 1, 2019 The Company adopted these ASUs on January 1, 2019, using a modified retrospective transition approach as of the date of adoption, which resulted in the recognition of $1.2 billion and $1.3 billion in right-of-use assets and associated lease liabilities, respectively, arising from operating leases in which the Company is the lessee, on the Company's Consolidated Balance Sheets. The amount of the right-of-use assets and associated lease liabilities recorded upon adoption was based primarily on the present value of unpaid future minimum lease payments, the amount of which was based on the population of leases in effect at the date of adoption. Right-of-use assets and lease liabilities recorded on the Company’s Consolidated Balance Sheets each totaled $1.2 billion at June 30, 2019. Standard Description Required Date of Adoption Effect on the Financial Statements or Other Significant Matters Standards Not Yet Adopted ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326) and subsequent related ASUs These ASUs create and amend ASC Topic 326, Financial Instruments - Credit Losses , which replaces the incurred loss impairment methodology with a current expected credit loss methodology for financial instruments measured at amortized cost and other commitments to extend credit. For this purpose, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of voluntary prepayments and considering available information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts. The resulting allowance for credit losses is deducted from the amortized cost basis of the financial assets to reflect the net amount expected to be collected on the financial assets. Additional quantitative and qualitative disclosures are required upon adoption. The change to the allowance for credit losses at the time of the adoption will be made with a cumulative effect adjustment to retained earnings. January 1, 2020 The Company formed a cross-functional team to oversee the implementation of these ASUs. A detailed implementation plan was developed and progress is nearly complete in regards to the identification and staging of data, development and validation of models, refinement of economic forecasting processes, and documentation of accounting policy decisions. Additionally, a new credit loss forecasting process has been implemented. In conjunction with this implementation, the Company modified the internal control environment, as appropriate. In the first half of 2019, the Company performed testing in which methodologies, processes, and internal controls were evaluated and refined. The Company will perform full parallel runs of the new methodology in the third and fourth quarters of 2019. The full parallel runs will emulate a regular estimation process including internal controls, supporting analytics, reserve estimation, documentation, subject matter expert reviews, and execution of the governance and approval process. Based on the results of these full parallel runs, the Company plans to further refine its processes and methodology prior to the adoption of these ASUs. ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment This ASU amends ASC Topic 350, Intangibles - Goodwill and Other , to simplify the subsequent measurement of goodwill, by eliminating Step 2 from the goodwill impairment test. The amendments require an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. This ASU requires an entity to recognize an impairment charge for the amount by which a reporting unit's carrying amount exceeds its fair value, with the loss limited to the total amount of goodwill allocated to that reporting unit. The ASU must be applied on a prospective basis. January 1, 2020 Early adoption is permitted. Based on the Company’s most recent qualitative goodwill impairment assessment performed as of October 1, 2018, there were no reporting units for which it was more-likely-than-not that the carrying amount of a reporting unit exceeded its respective fair value; therefore, this ASU would not currently have an impact on the Company’s Consolidated Financial Statements or related disclosures. However, if subsequent to adoption, the carrying amount of a reporting unit exceeds its respective fair value, the Company would be required to recognize an impairment charge for the amount that the carrying value exceeds the fair value. ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract This ASU amends ASC Subtopic 350-40, Intangibles - Goodwill and Other - Internal-Use Software , to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company may apply this ASU either retrospectively, or prospectively to all implementation costs incurred after the date of adoption. January 1, 2020 Early adoption is permitted. The Company’s current accounting policy for capitalizing implementation costs incurred in a hosting arrangement generally aligns with the requirements of this ASU; therefore, the Company's adoption of this ASU is not expected to have a material impact on the Company’s Consolidated Financial Statements or related disclosures.
