Summary of Significant Accounting Principles	6 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Principles	Summary of Significant Accounting Principles Bank of America Corporation, a bank holding company and a financial holding company, provides a diverse range of financial services and products throughout the U.S. and in certain international markets. The term “the Corporation” as used herein may refer to Bank of America Corporation individually, Bank of America Corporation and its subsidiaries, or certain of Bank of America Corporation’s subsidiaries or affiliates. Principles of Consolidation and Basis of Presentation The Consolidated Financial Statements include the accounts of the Corporation and its majority-owned subsidiaries and those variable interest entities (VIEs) where the Corporation is the primary beneficiary. Intercompany accounts and transactions have been eliminated. Results of operations of acquired companies are included from the dates of acquisition and for VIEs, from the dates that the Corporation became the primary beneficiary. Assets held in an agency or fiduciary capacity are not included in the Consolidated Financial Statements. The Corporation accounts for investments in companies for which it owns a voting interest and for which it has the ability to exercise significant influence over operating and financing decisions using the equity method of accounting. These investments are included in other assets. Equity method investments are subject to impairment testing, and the Corporation’s proportionate share of income or loss is included in other income. The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect reported amounts and disclosures. Realized results could differ from those estimates and assumptions. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The nature of the Corporation's business is such that the results of any interim period are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period results have been made. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission (SEC). Certain prior-period amounts have been reclassified to conform to current period presentation. On June 1, 2017, the Corporation completed the previously-announced sale of its non-U.S. consumer credit card business to a third party. The Corporation has indemnified the purchaser for substantially all payment protection insurance (PPI) exposure above reserves assumed by the purchaser. The impact of the sale is an after-tax gain of $103 million , and is presented in the Consolidated Statement of Income as other income of $793 million and an income tax expense of $690 million . The income tax expense is related to gains on the derivatives used to hedge the currency risk of the net investment. Total cash proceeds from the sale were $10.9 billion . The assets of the business sold primarily included consumer credit card receivables of $9.8 billion and $9.2 billion at June 1, 2017 and December 31, 2016 , and goodwill of $775 million at both of those period ends. This business was included in All Other . New Accounting Pronouncements Accounting for Financial Instruments -- Credit Losses The Financial Accounting Standards Board (FASB) issued a new accounting standard effective on January 1, 2020, with early adoption permitted on January 1, 2019, that will require the earlier recognition of credit losses on loans and other financial instruments based on an expected loss model, replacing the incurred loss model that is currently in use. The standard also requires expanded credit quality disclosures, including credit quality indicators disaggregated by vintage. The Corporation is in the process of identifying and implementing required changes to loan loss estimation models and processes and evaluating the impact of this new accounting standard, which at the date of adoption is expected to increase the allowance for credit losses with a resulting negative adjustment to retained earnings. Revenue Recognition The FASB issued a new accounting standard effective on January 1, 2018 for recognizing revenue from contracts with customers. While the new standard does not apply to revenue associated with loans or securities, the Corporation has identified the customer contracts within the scope of the new standard and is assessing the related revenues to determine if any accounting or internal control changes will be required for the new provisions. The timing of the Corporation’s revenue recognition is not expected to materially change. The classification of certain contract costs continues to be evaluated, and the final interpretation may impact the presentation of certain contract costs. Overall, the Corporation does not expect the new standard to have a material impact on its consolidated financial position, results of operations or disclosures in the Notes to the Consolidated Financial Statements. Lease Accounting The FASB issued a new accounting standard effective on January 1, 2019 that requires substantially all leases to be recorded as assets and liabilities on the balance sheet. This new accounting standard uses a modified retrospective transition that will be applied to all prior periods presented. The Corporation is in the process of reviewing its existing lease portfolios, as well as other service contracts for embedded leases, to evaluate the impact of the new accounting standard on the financial statements, as well as the impact to regulatory capital and risk-weighted assets. The effect of the adoption will depend on its lease portfolio at the time of transition; however, the Corporation does not expect the new accounting standard to have a material impact on its consolidated financial position, results of operations or disclosures in the Notes to the Consolidated Financial Statements. Recognition and Measurement of Financial Assets and Financial Liabilities The FASB issued a new accounting standard effective on January 1, 2018, with early adoption permitted for the provisions related to debit valuation adjustments (DVA), on recognition and measurement of financial instruments, including certain equity investments and financial liabilities recorded at fair value under the fair value option. In 2015, the Corporation early adopted, retrospective to January 1, 2015, the provisions of this new accounting standard related to DVA on financial liabilities accounted for under the fair value option. The Corporation does not expect the remaining provisions of this new accounting standard to have a material impact on its consolidated financial position, results of operations or disclosures in the Notes to the Consolidated Financial Statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Derivative Balances Derivatives are entered into on behalf of customers, for trading or to support risk management activities. Derivatives used in risk management activities include derivatives that may or may not be designated in qualifying hedge accounting relationships. Derivatives that are not designated in qualifying hedge accounting relationships are referred to as other risk management derivatives. For more information on the Corporation’s derivatives and hedging activities, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The following tables present derivative instruments included on the Consolidated Balance Sheet in derivative assets and liabilities at June 30, 2017 and December 31, 2016 .

Offsetting of Derivatives The Corporation enters into International Swaps and Derivatives Association, Inc. (ISDA) master netting agreements or similar agreements with substantially all of the Corporation’s derivative counterparties. Where legally enforceable, these master netting agreements give the Corporation, in the event of default by the counterparty, the right to liquidate securities held as collateral and to offset receivables and payables with the same counterparty. For additional information on the offsetting of derivative assets and liabilities, see Note 2 – Derivatives to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The following table presents derivative instruments included in derivative assets and liabilities on the Consolidated Balance Sheet at June 30, 2017 and December 31, 2016 by primary risk (e.g., interest rate risk) and the platform, where applicable, on which these derivatives are transacted. Balances are presented on a gross basis, prior to the application of counterparty and cash collateral netting. Total gross derivative assets and liabilities are adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements which includes reducing the balance for counterparty netting and cash collateral received or paid.

(2) Consists of derivatives entered into under master netting agreements where the enforceability of these agreements is uncertain under bankruptcy laws in some countries or industries. (3) Derivative assets and liabilities reflect a central clearing counterparty's amendments to legally re-characterize daily cash variation margin from collateral, which secures an outstanding exposure, to settlement, which discharges an outstanding exposure, effective in January 2017. (4) Amounts are limited to the derivative asset/liability balance and, accordingly, do not include excess collateral received/pledged. Financial instruments collateral includes securities collateral received or pledged and cash securities held and posted at third-party custodians that are not offset on the Consolidated Balance Sheet but shown as a reduction to derive net derivative assets and liabilities. ALM and Risk Management Derivatives The Corporation’s asset and liability management (ALM) and risk management activities include the use of derivatives to mitigate risk to the Corporation including derivatives designated in qualifying hedge accounting relationships and derivatives used in other risk management activities. For additional information, see Note 2 – Derivatives to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. Derivatives Designated as Accounting Hedges The Corporation uses various types of interest rate, commodity and foreign exchange derivative contracts to protect against changes in the fair value of its assets and liabilities due to fluctuations in interest rates, commodity prices and exchange rates (fair value hedges). The Corporation also uses these types of contracts and equity derivatives to protect against changes in the cash flows of its assets and liabilities, and other forecasted transactions (cash flow hedges). The Corporation hedges its net investment in consolidated non-U.S. operations determined to have functional currencies other than the U.S. Dollar using forward exchange contracts and cross-currency basis swaps, and by issuing foreign currency-denominated debt (net investment hedges). Fair Value Hedges The following table summarizes information related to fair value hedges for the three and six months ended June 30, 2017 and 2016 , including hedges of interest rate risk on long-term debt that were acquired as part of a business combination and redesignated at that time. At redesignation, the fair value of the derivatives was positive. As the derivatives mature, the fair value will approach zero. As a result, ineffectiveness will occur and the fair value changes in the derivatives and the long-term debt being hedged may be directionally the same in certain scenarios. Based on a regression analysis, the derivatives continue to be highly effective at offsetting changes in the fair value of the long-term debt attributable to interest rate risk. Derivatives Designated as Fair Value Hedges Gains (Losses) Three Months Ended June 30, 2017 Six Months Ended June 30, 2017 (Dollars in millions) Derivative Hedged Hedge Derivative Hedged Item Hedge Ineffectiveness Interest rate risk on long-term debt (1) $ 272 $ (422 ) $ (150 ) $ (478 ) $ 144 $ (334 ) Interest rate and foreign currency risk on long-term debt (1) 901 (877 ) 24 1,024 (1,010 ) 14 Interest rate risk on available-for-sale securities (2) (80 ) 70 (10 ) (63 ) 33 (30 ) Price risk on commodity inventory (3) 2 (1 ) 1 8 (7 ) 1 Total $ 1,095 $ (1,230 ) $ (135 ) $ 491 $ (840 ) $ (349 ) Three Months Ended June 30, 2016 Six Months Ended June 30, 2016 Interest rate risk on long-term debt (1) $ 1,263 $ (1,380 ) $ (117 ) $ 3,924 $ (4,234 ) $ (310 ) Interest rate and foreign currency risk on long-term debt (1) (495 ) 487 (8 ) 344 (359 ) (15 ) Interest rate risk on available-for-sale securities (2) (215 ) 198 (17 ) (366 ) 330 (36 ) Price risk on commodity inventory (3) (8 ) 8 — (6 ) 6 — Total $ 545 $ (687 ) $ (142 ) $ 3,896 $ (4,257 ) $ (361 ) (1) Amounts are recorded in interest expense on long-term debt and in other income. (2) Amounts are recorded in interest income on debt securities. (3) Amounts relating to commodity inventory are recorded in trading account profits. Cash Flow and Net Investment Hedges The table below summarizes certain information related to cash flow hedges and net investment hedges for the three and six months ended June 30, 2017 and 2016 . Of the $763 million after-tax net loss ( $1.2 billion pre-tax) on derivatives in accumulated other comprehensive income (OCI) at June 30, 2017 , $141 million after-tax ( $226 million pre-tax) is expected to be reclassified into earnings in the next 12 months. These net losses reclassified into earnings are expected to primarily reduce net interest income related to the respective hedged items. Amounts related to price risk on restricted stock awards reclassified from accumulated OCI are recorded in personnel expense. For terminated cash flow hedges, the time period over which the majority of the forecasted transactions are hedged is approximately seven years , with a maximum length of time for certain forecasted transactions of 19 years .

(2) Gains (losses) recognized in accumulated OCI are primarily related to the change in the Corporation’s stock price for the period. (3) Substantially all of the gains in income reclassified from accumulated OCI are comprised of the gain recognized on derivatives used to hedge the currency risk of the Corporation's net investment in its non-U.S. consumer credit card business, which was sold on June 1, 2017. For additional information, see Note 12 – Accumulated Other Comprehensive Income (Loss) . Other Risk Management Derivatives Other risk management derivatives are used by the Corporation to reduce certain risk exposures. These derivatives are not qualifying accounting hedges because either they did not qualify for or were not designated as accounting hedges. The table below presents gains (losses) on these derivatives for the three and six months ended June 30, 2017 and 2016 . These gains (losses) are largely offset by the income or expense that is recorded on the hedged item.

The net gains on IRLCs related to the origination of mortgage loans that are held-for-sale, which are not included in the table but are considered derivative instruments, were $60 million and $ 116 million for the three and six months ended June 30, 2017 compared to $ 177 million and $ 329 million for the same periods in 2016. (2) Primarily related to derivatives that are economic hedges of credit risk on loans. Net gains (losses) on these derivatives are recorded in other income. (3) Primarily related to hedges of debt securities carried at fair value and hedges of foreign currency-denominated debt. Gains (losses) on these derivatives and the related hedged items are recorded in other income. (4) Gains (losses) on these derivatives are recorded in personnel expense. Transfers of Financial Assets with Risk Retained through Derivatives The Corporation enters into certain transactions involving the transfer of financial assets that are accounted for as sales where substantially all of the economic exposure to the transferred financial assets is retained through derivatives (e.g., interest rate and/or credit), but the Corporation does not retain control over the assets transferred. Through June 30, 2017 and December 31, 2016 , the Corporation transferred $6.3 billion and $6.6 billion of non-U.S. government-guaranteed mortgage-backed securities (MBS) to a third-party trust and retained economic exposure to the transferred assets through derivative contracts. In connection with these transfers, the Corporation received gross cash proceeds of $6.3 billion and $6.6 billion at the transfer dates. At June 30, 2017 and December 31, 2016 , the fair value of the transferred securities was $6.2 billion and $6.3 billion . Derivative assets of $43 million at both period ends and liabilities of $7 million and $10 million were recorded at June 30, 2017 and December 31, 2016 , and are included in credit derivatives in the derivative instruments table on page 76 . Sales and Trading Revenue The Corporation enters into trading derivatives to facilitate client transactions and to manage risk exposures arising from trading account assets and liabilities. It is the Corporation’s policy to include these derivative instruments in its trading activities which include derivatives and non-derivative cash instruments. The resulting risk from these derivatives is managed on a portfolio basis as part of the Corporation’s Global Markets business segment. For more information on sales and trading revenue, see Note 2 – Derivatives to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The following table, which includes both derivatives and non-derivative cash instruments, identifies the amounts in the respective income statement line items attributable to the Corporation’s sales and trading revenue in Global Markets , categorized by primary risk, for the three and six months ended June 30, 2017 and 2016 . The difference between total trading account profits in the following table and in the Consolidated Statement of Income represents trading activities in business segments other than Global Markets . This table includes debit valuation and funding valuation adjustment (DVA/FVA) gains (losses). Global Markets results in Note 17 – Business Segment Information are presented on a fully taxable-equivalent (FTE) basis. The following table is not presented on an FTE basis.

Credit Derivatives The Corporation enters into credit derivatives primarily to facilitate client transactions and to manage credit risk exposures. Credit derivatives derive value based on an underlying third-party referenced obligation or a portfolio of referenced obligations and generally require the Corporation, as the seller of credit protection, to make payments to a buyer upon the occurrence of a pre-defined credit event. Such credit events generally include bankruptcy of the referenced credit entity and failure to pay under the obligation, as well as acceleration of indebtedness and payment repudiation or moratorium. For credit derivatives based on a portfolio of referenced credits or credit indices, the Corporation may not be required to make payment until a specified amount of loss has occurred and/or may only be required to make payment up to a specified amount. Credit derivative instruments where the Corporation is the seller of credit protection and their expiration at June 30, 2017 and December 31, 2016 are summarized in the following table.

The Corporation considers ratings of BBB- or higher as investment grade. Non-investment grade includes non-rated credit derivative instruments. The Corporation discloses internal categorizations of investment grade and non-investment grade consistent with how risk is managed for these instruments. The notional amount represents the maximum amount payable by the Corporation for most credit derivatives. However, the Corporation does not monitor its exposure to credit derivatives based solely on the notional amount because this measure does not take into consideration the probability of occurrence. As such, the notional amount is not a reliable indicator of the Corporation’s exposure to these contracts. Instead, a risk framework is used to define risk tolerances and establish limits to help ensure that certain credit risk-related losses occur within acceptable, predefined limits. Credit-related notes in the table on page 82 include investments in securities issued by collateralized debt obligation (CDO), collateralized loan obligation (CLO) and credit-linked note vehicles. These instruments are primarily classified as trading securities. The carrying value of these instruments equals the Corporation’s maximum exposure to loss. The Corporation is not obligated to make any payments to the entities under the terms of the securities owned. Credit-related Contingent Features and Collateral The majority of the Corporation's derivative contracts contain credit-risk related features, primarily in the form of ISDA master netting agreements and credit support documentation that enhance the creditworthiness of these instruments. Therefore, events such as a credit rating downgrade or a breach of credit covenants would typically require an increase in the amount of collateral required of the counterparty, where applicable, and/or allow the Corporation to take additional protective measures such as early termination of all trades. At June 30, 2017 and December 31, 2016 , the Corporation held cash and securities collateral of $77.0 billion and $85.5 billion , and posted cash and securities collateral of $67.2 billion and $71.1 billion in the normal course of business under derivative agreements, excluding cross-product margining agreements where clients are permitted to margin on a net basis for both derivative and secured financing arrangements. In connection with certain OTC derivative contracts and other trading agreements, the Corporation can be required to provide additional collateral or to terminate transactions with certain counterparties in the event of a downgrade of the senior debt ratings of the Corporation or certain subsidiaries. At June 30, 2017 , the amount of collateral, calculated based on the terms of the contracts, that the Corporation and certain subsidiaries could be required to post to counterparties but had not yet posted to counterparties was approximately $2.5 billion , including $1.8 billion for Bank of America, N.A. (BANA). For more information on credit-related contingent features and collateral, see Note 2 – Derivatives to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K.

Assumptions used for the underlying loans that support the MBS can vary widely from loan to loan and are influenced by such factors as loan interest rate, geographic location of the borrower, borrower characteristics and collateral type. Based on these assumptions, the Corporation then determines how the underlying collateral cash flows will be distributed to each MBS issued from the applicable special purpose entity. Expected principal and interest cash flows on an impaired AFS debt security are discounted using the effective yield of each individual impaired AFS debt security. Significant assumptions used in estimating the expected cash flows for measuring credit losses on non-agency RMBS were as follows at June 30, 2017 . Significant Assumptions Range (1) Weighted- 10th Percentile (2) 90th Percentile (2) Prepayment speed 11.5 % 2.9 % 20.0 % Loss severity 20.3 9.2 37.4 Life default rate 22.0 1.2 79.2 (1) Represents the range of inputs/assumptions based upon the underlying collateral. (2) The value of a variable below which the indicated percentile of observations will fall. Annual constant prepayment speed and loss severity rates are projected considering collateral characteristics such as loan-to-value (LTV), creditworthiness of borrowers as measured using Fair Isaac Corporation (FICO) scores, and geographic concentrations. The weighted-average severity by collateral type was 17.2 percent for prime, 18.9 percent for Alt-A and 30.4 percent for subprime at June 30, 2017 . Additionally, default rates are projected by considering collateral characteristics including, but not limited to, LTV, FICO and geographic concentration. Weighted-average life default rates by collateral type were 15.8 percent for prime, 22.8 percent for Alt-A and 23.0 percent for subprime at June 30, 2017 . The remaining contractual maturity distribution and yields of the Corporation’s debt securities carried at fair value and HTM debt securities at June 30, 2017 are summarized in the table below. Actual duration and yields may differ as prepayments on the loans underlying the mortgages or other asset-backed securities (ABS) are passed through to the Corporation.

(10) Includes non-U.S. credit card loans, which are included in assets of business held for sale on the Consolidated Balance Sheet. (11) The Corporation pledged $143.1 billion of loans to secure potential borrowing capacity with the Federal Reserve Bank and FHLB. This amount is not included in the parenthetical disclosure of loans and leases pledged as collateral on the Consolidated Balance Sheet as there were no related outstanding borrowings. The Corporation categorizes consumer real estate loans as core and non-core based on loan and customer characteristics such as origination date, product type, LTV, FICO score and delinquency status consistent with its current consumer and mortgage servicing strategy. Generally, loans that were originated after January 1, 2010, qualified under government-sponsored enterprise (GSE) underwriting guidelines, or otherwise met the Corporation's underwriting guidelines in place in 2015 are characterized as core loans. Loans held in legacy private-label securitizations, government-insured loans originated prior to 2010, loan products no longer originated, and loans originated prior to 2010 and classified as nonperforming or modified in a troubled debt restructuring (TDR) prior to 2016 are generally characterized as non-core loans, and are principally run-off portfolios. The Corporation has entered into long-term credit protection agreements with FNMA and FHLMC on loans totaling $6.6 billion and $6.4 billion at June 30, 2017 and December 31, 2016 , providing full credit protection on residential mortgage loans that become severely delinquent. All of these loans are individually insured and therefore the Corporation does not record an allowance for credit losses related to these loans. Nonperforming Loans and Leases The Corporation classifies junior-lien home equity loans as nonperforming when the first-lien loan becomes 90 days past due even if the junior-lien loan is performing. At June 30, 2017 and December 31, 2016 , $374 million and $428 million of such junior-lien home equity loans were included in nonperforming loans. The Corporation classifies consumer real estate loans that have been discharged in Chapter 7 bankruptcy and not reaffirmed by the borrower as TDRs, irrespective of payment history or delinquency status, even if the repayment terms for the loan have not been otherwise modified. The Corporation continues to have a lien on the underlying collateral. At June 30, 2017 , nonperforming loans discharged in Chapter 7 bankruptcy with no change in repayment terms were $451 million of which $274 million were current on their contractual payments, while $147 million were 90 days or more past due. Of the contractually current nonperforming loans, approximately 81 percent were discharged in Chapter 7 bankruptcy over 12 months ago, and approximately 71 percent were discharged 24 months or more ago. During the three and six months ended June 30, 2017 , the Corporation sold nonperforming and other delinquent consumer real estate loans with a carrying value of $323 million and $465 million , including $204 million of PCI loans for both periods, compared to $417 million and $1.4 billion , including $150 million and $324 million of PCI loans, for the same periods in 2016 . During the six months ended June 30, 2017 , the Corporation transferred nonperforming loans with a net carrying value of $198 million to held-for-sale. There were no transfers of nonperforming loans to held-for-sale for the same period in 2016. The table below presents the Corporation’s nonperforming loans and leases including nonperforming TDRs, and loans accruing past due 90 days or more at June 30, 2017 and December 31, 2016 . Nonperforming loans held-for-sale (LHFS) are excluded from nonperforming loans and leases as they are recorded at either fair value or the lower of cost or fair value. For more information on the criteria for classification as nonperforming, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K.

At June 30, 2017 and December 31, 2016 , residential mortgage includes $2.4 billion and $3.0 billion of loans on which interest has been curtailed by the Federal Housing Administration (FHA), and therefore are no longer accruing interest, although principal is still insured, and $1.3 billion and $1.8 billion of loans on which interest is still accruing. n/a = not applicable Credit Quality Indicators The Corporation monitors credit quality within its Consumer Real Estate, Credit Card and Other Consumer, and Commercial portfolio segments based on primary credit quality indicators. Within the consumer portfolio segments, the primary credit quality indicators are refreshed LTV and refreshed FICO score. Refreshed LTV measures the carrying value of the loan as a percentage of the value of the property securing the loan, refreshed quarterly. FICO score measures the creditworthiness of the borrower based on the financial obligations of the borrower and the borrower’s credit history. FICO scores are typically refreshed quarterly or more frequently. Within the Commercial portfolio segment, loans are evaluated using the internal classifications of pass rated or reservable criticized as the primary credit quality indicators. In addition to these primary credit quality indicators, the Corporation uses other credit quality indicators for certain types of loans. For more information on the portfolio segments and credit quality indicators, see Note 1 – Summary of Significant Accounting Principles and Note 4 – Outstanding Loans and Leases to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The following tables present certain credit quality indicators for the Corporation’s Consumer Real Estate, Credit Card and Other Consumer, and Commercial portfolio segments, by class of financing receivables, at June 30, 2017 and December 31, 2016 .

Impaired Loans and Troubled Debt Restructurings A loan is considered impaired when, based on current information, it is probable that the Corporation will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming commercial loans and all consumer and commercial TDRs. Impaired loans exclude nonperforming consumer loans and nonperforming commercial leases unless they are classified as TDRs. Loans accounted for under the fair value option are also excluded. PCI loans are excluded and reported separately on page 101 . For more information, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. Consumer Real Estate Impaired consumer real estate loans within the Consumer Real Estate portfolio segment consist entirely of TDRs. Excluding PCI loans, most modifications of consumer real estate loans meet the definition of TDRs when a binding offer is extended to a borrower. For more information on impaired consumer real estate loans, see Note 4 – Outstanding Loans and Leases to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. Consumer real estate loans that have been discharged in Chapter 7 bankruptcy with no change in repayment terms and not reaffirmed by the borrower of $1.3 billion were included in TDRs at June 30, 2017 , of which $451 million were classified as nonperforming and $465 million were loans fully-insured by the FHA. For more information on loans discharged in Chapter 7 bankruptcy, see Nonperforming Loans and Leases in this Note. At June 30, 2017 and December 31, 2016 , remaining commitments to lend additional funds to debtors whose terms have been modified in a consumer real estate TDR were immaterial. Consumer real estate foreclosed properties totaled $285 million and $363 million at June 30, 2017 and December 31, 2016 . The carrying value of consumer real estate loans, including fully-insured and PCI loans, for which formal foreclosure proceedings were in process as of June 30, 2017 was $4.1 billion . During the three and six months ended June 30, 2017 , the Corporation reclassified $226 million and $426 million of consumer real estate loans to foreclosed properties or, for properties acquired upon foreclosure of certain government-guaranteed loans (principally FHA-insured loans), to other assets. This compared to reclassifications of $392 million and $808 million for the same periods in 2016 . The reclassifications represent non-cash investing activities and, accordingly, are not reflected on the Consolidated Statement of Cash Flows. The table below provides the unpaid principal balance, carrying value and related allowance at June 30, 2017 and December 31, 2016 , and the average carrying value and interest income recognized for the three and six months ended June 30, 2017 and 2016 for impaired loans in the Corporation’s Consumer Real Estate portfolio segment. Certain impaired consumer real estate loans do not have a related allowance as the current valuation of these impaired loans exceeded the carrying value, which is net of previously recorded charge-offs.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Securitizations and Other Variable Interest Entities	Securitizations and Other Variable Interest Entities The Corporation utilizes VIEs in the ordinary course of business to support its own and its customers’ financing and investing needs. For more information on the Corporation’s use of VIEs, see Note 1 – Summary of Significant Accounting Principles and Note 6 – Securitizations and Other Variable Interest Entities to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The tables in this Note present the assets and liabilities of consolidated and unconsolidated VIEs at June 30, 2017 and December 31, 2016 , in situations where the Corporation has continuing involvement with transferred assets or if the Corporation otherwise has a variable interest in the VIE. The tables also present the Corporation’s maximum loss exposure at June 30, 2017 and December 31, 2016 resulting from its involvement with consolidated VIEs and unconsolidated VIEs in which the Corporation holds a variable interest. The Corporation’s maximum loss exposure is based on the unlikely event that all of the assets in the VIEs become worthless and incorporates not only potential losses associated with assets recorded on the Consolidated Balance Sheet but also potential losses associated with off-balance sheet commitments, such as unfunded liquidity commitments and other contractual arrangements. The Corporation’s maximum loss exposure does not include losses previously recognized through write-downs of assets. The Corporation invests in ABS issued by third-party VIEs with which it has no other form of involvement and enters into certain commercial lending arrangements that may also incorporate the use of VIEs, for example to hold collateral. These securities and loans are included in Note 3 – Securities or Note 4 – Outstanding Loans and Leases . In addition, the Corporation uses VIEs such as trust preferred securities trusts in connection with its funding activities. For additional information, see Note 11 – Long-term Debt to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The Corporation uses VIEs, such as common trust funds managed within Global Wealth & Investment Management ( GWIM) , to provide investment opportunities for clients. These VIEs, which are generally not consolidated by the Corporation, as applicable, are not included in the tables herein. Except as described below, the Corporation did not provide financial support to consolidated or unconsolidated VIEs during the six months ended June 30, 2017 or the year ended December 31, 2016 that it was not previously contractually required to provide, nor does it intend to do so. First-lien Mortgage Securitizations First-lien Mortgages As part of its mortgage banking activities, the Corporation securitizes a portion of the first-lien residential mortgage loans it originates or purchases from third parties. Except as described below and in Note 7 – Representations and Warranties Obligations and Corporate Guarantees , the Corporation does not provide guarantees or recourse to the securitization trusts other than standard representations and warranties. The table below summarizes select information related to first-lien mortgage securitizations for the three and six months ended June 30, 2017 and 2016 . First-lien Mortgage Securitizations Residential Mortgage - Agency Commercial Mortgage Three Months Ended June 30 Six Months Ended June 30 Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2017 2016 2017 2016 2017 2016 2017 2016 Cash proceeds from new securitizations (1) $ 3,302 $ 4,375 $ 7,958 $ 11,449 $ 1,097 $ 732 $ 1,706 $ 1,979 Gain (loss) on securitizations (2) 61 70 100 233 35 (6 ) 53 (9 ) Repurchases from securitization trusts (3) 602 645 1,474 1,374 — — — — (1) The Corporation transfers residential mortgage loans to securitizations sponsored by the GSEs or Government National Mortgage Association (GNMA) in the normal course of business and receives RMBS in exchange which may then be sold into the market to third-party investors for cash proceeds. (2) A majority of the first-lien residential and commercial mortgage loans securitized are initially classified as LHFS and accounted for under the fair value option. Gains recognized on these LHFS prior to securitization, which totaled $42 million and $132 million , net of hedges, during the three and six months ended June 30, 2017 compared to $92 million and $200 million for the same periods in 2016 , are not included in the table above. (3) The Corporation may have the option to repurchase delinquent loans out of securitization trusts, which reduces the amount of servicing advances it is required to make. The Corporation may also repurchase loans from securitization trusts to perform modifications. Repurchased loans include FHA-insured mortgages collateralizing GNMA securities. In addition to cash proceeds as reported in the table above, the Corporation received securities with an initial fair value of $288 million and $563 million in connection with first-lien mortgage securitizations for the three and six months ended June 30, 2017 compared to $1.0 billion and $1.9 billion for the same periods in 2016 . The receipt of these securities represents non-cash operating and investing activities and, accordingly, is not reflected on the Consolidated Statement of Cash Flows. Substantially all of these securities were initially classified as Level 2 assets within the fair value hierarchy. During the three and six months ended June 30, 2017 and 2016 , there were no changes to the initial classification. The Corporation recognizes consumer MSRs from the sale or securitization of consumer real estate loans. The unpaid principal balance of loans serviced for investors, including residential mortgage and home equity loans, totaled $304.9 billion and $371.0 billion at June 30, 2017 and 2016 . Servicing fee and ancillary fee income on serviced loans was $233 million and $478 million during the three and six months ended June 30, 2017 compared to $299 million and $601 million for the same periods in 2016 . Servicing advances on serviced loans, including loans serviced for others and loans held for investment were $5.4 billion and $6.2 billion at June 30, 2017 and December 31, 2016 . For more information on MSRs, see Note 14 – Fair Value Measurements . During the six months ended June 30, 2016 , the Corporation deconsolidated agency residential mortgage securitization vehicles with total assets of $2.8 billion following the sale of retained interests to third parties, after which the Corporation no longer had the unilateral ability to liquidate the vehicles. Gains on sale of $114 million related to the deconsolidations were recorded in other income in the Consolidated Statement of Income. The following table summarizes select information related to first-lien mortgage securitization trusts in which the Corporation held a variable interest at June 30, 2017 and December 31, 2016 .

For both consolidated and unconsolidated home equity loan VIEs, the maximum loss exposure excludes the liability for representations and warranties obligations and corporate guarantees. For additional information, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees . (2) At June 30, 2017 and December 31, 2016 , loans and leases in the consolidated credit card trust included $15.4 billion and $17.6 billion of seller’s interest. (3) At June 30, 2017 and December 31, 2016 , all other assets in the consolidated credit card trust included restricted cash, certain short-term investments, and unbilled accrued interest and fees. (4) As a holder of these securities, the Corporation receives scheduled principal and interest payments. During the three and six months ended June 30, 2017 , the Corporation recognized $0 and $2 million compared to $1 million and $2 million for the same periods in 2016 of credit-related impairment losses in earnings on securities classified as AFS debt securities. During the three and six months ended June 30, 2017 and 2016 , the Corporation recognized no credit-related impairment losses in earnings on securities classified as HTM. (5) The retained senior and subordinate securities were valued using quoted market prices or observable market inputs (Level 2 of the fair value hierarchy). (6) Total assets include loans the Corporation transferred with which it has continuing involvement, which may include servicing the loan. Home Equity Loans The Corporation retains interests in home equity securitization trusts to which it transferred home equity loans. These retained interests include senior and subordinate securities and residual interests. In addition, the Corporation may be obligated to provide subordinate funding to the trusts during a rapid amortization event. This obligation is included in the maximum loss exposure in the table above. The charges that will ultimately be recorded as a result of the rapid amortization events depend on the undrawn available credit on the home equity lines, performance of the loans, the amount of subsequent draws and the timing of related cash flows. Credit Card Securitizations The Corporation securitizes originated and purchased credit card loans. The Corporation’s continuing involvement with the securitization trust includes servicing the receivables, retaining an undivided interest (seller’s interest) in the receivables, and holding certain retained interests including senior and subordinate securities, subordinate interests in accrued interest and fees on the securitized receivables, and cash reserve accounts. For the six months ended June 30, 2017 and 2016 , $2.0 billion and $750 million of new senior debt securities were issued to third-party investors from the credit card securitization trust. At both June 30, 2017 and December 31, 2016 , the Corporation held subordinate securities issued by the credit card securitization trust with a notional principal amount of $7.5 billion . These securities serve as a form of credit enhancement to the senior debt securities and have a stated interest rate of zero percent . There were $323 million of these subordinate securities issued during the six months ended June 30, 2017 compared to $121 million for the same period in 2016 . Resecuritization Trusts The Corporation transfers securities, typically MBS, into resecuritization vehicles at the request of customers seeking securities with specific characteristics. Generally, there are no significant ongoing activities performed in a resecuritization trust and no single investor has the unilateral ability to liquidate the trust. The Corporation resecuritized $7.3 billion and $15.1 billion of securities during the three and six months ended June 30, 2017 compared to $8.1 billion and $14.7 billion for the same periods in 2016 . Securities transferred into resecuritization vehicles during the three and six months ended June 30, 2017 and 2016 were measured at fair value with changes in fair value recorded in trading account profits prior to the resecuritization and no gain or loss on sale was recorded. Resecuritization proceeds included securities with an initial fair value of $1.1 billion and $1.8 billion during the three and six months ended June 30, 2017 compared to $1.1 billion and $2.2 billion for the same periods in 2016 . All of the securities received as resecuritization proceeds were classified as trading securities and were categorized as Level 2 within the fair value hierarchy. Municipal Bond Trusts The Corporation administers municipal bond trusts that hold highly-rated, long-term, fixed-rate municipal bonds. The trusts obtain financing by issuing floating-rate trust certificates that reprice on a weekly or other short-term basis to third-party investors. The Corporation’s liquidity commitments to unconsolidated municipal bond trusts, including those for which the Corporation was transferor, totaled $1.6 billion at both June 30, 2017 and December 31, 2016 . The weighted-average remaining life of bonds held in the trusts at June 30, 2017 was 5.3 years. There were no material write-downs or downgrades of assets or issuers during the six months ended June 30, 2017 and 2016 . Other Variable Interest Entities The table below summarizes select information related to other VIEs in which the Corporation held a variable interest at June 30, 2017 and December 31, 2016 . Other VIEs June 30, 2017 December 31, 2016 (Dollars in millions) Consolidated Unconsolidated Total Consolidated Unconsolidated Total Maximum loss exposure $ 5,428 $ 18,105 $ 23,533 $ 6,114 $ 17,754 $ 23,868 On-balance sheet assets Trading account assets $ 2,470 $ 277 $ 2,747 $ 2,358 $ 233 $ 2,591 Debt securities carried at fair value — 231 231 — 122 122 Loans and leases 2,942 3,746 6,688 3,399 3,249 6,648 Allowance for loan and lease losses (8 ) (30 ) (38 ) (9 ) (24 ) (33 ) Loans held-for-sale 93 102 195 188 464 652 All other assets 151 13,410 13,561 369 13,156 13,525 Total $ 5,648 $ 17,736 $ 23,384 $ 6,305 $ 17,200 $ 23,505 On-balance sheet liabilities Long-term debt (1) $ 210 $ — $ 210 $ 395 $ — $ 395 All other liabilities 23 3,065 3,088 24 2,959 2,983 Total $ 233 $ 3,065 $ 3,298 $ 419 $ 2,959 $ 3,378 Total assets of VIEs $ 5,648 $ 66,088 $ 71,736 $ 6,305 $ 62,269 $ 68,574 (1) Includes $13 million and $229 million of long-term debt at June 30, 2017 and December 31, 2016 issued by other consolidated VIEs, which has recourse to the general credit of the Corporation. Customer Vehicles Customer vehicles include credit-linked, equity-linked and commodity-linked note vehicles, repackaging vehicles, and asset acquisition vehicles, which are typically created on behalf of customers who wish to obtain market or credit exposure to a specific company, index, commodity or financial instrument. The Corporation’s maximum loss exposure to consolidated and unconsolidated customer vehicles totaled $2.2 billion and $2.9 billion at June 30, 2017 and December 31, 2016 , including the notional amount of derivatives to which the Corporation is a counterparty, net of losses previously recorded, and the Corporation’s investment, if any, in securities issued by the vehicles. The Corporation also had liquidity commitments, including written put options and collateral value guarantees, with certain unconsolidated vehicles of $41 million and $323 million at June 30, 2017 and December 31, 2016 , that are included in the table above. Collateralized Debt Obligation Vehicles The Corporation receives fees for structuring CDO vehicles, which hold diversified pools of fixed-income securities, typically corporate debt or ABS, which the CDO vehicles fund by issuing multiple tranches of debt and equity securities. CDOs are generally managed by third-party portfolio managers. The Corporation typically transfers assets to these CDOs, holds securities issued by the CDOs and may be a derivative counterparty to the CDOs. The Corporation’s maximum loss exposure to consolidated and unconsolidated CDOs totaled $508 million and $430 million at June 30, 2017 and December 31, 2016 . Investment Vehicles The Corporation sponsors, invests in or provides financing, which may be in connection with the sale of assets, to a variety of investment vehicles that hold loans, real estate, debt securities or other financial instruments and are designed to provide the desired investment profile to investors or the Corporation. At June 30, 2017 and December 31, 2016 , the Corporation’s consolidated investment vehicles had total assets of $626 million and $846 million . The Corporation also held investments in unconsolidated vehicles with total assets of $21.2 billion and $17.3 billion at June 30, 2017 and December 31, 2016 . The Corporation’s maximum loss exposure associated with both consolidated and unconsolidated investment vehicles totaled $4.9 billion and $5.1 billion at June 30, 2017 and December 31, 2016 comprised primarily of on-balance sheet assets less non-recourse liabilities. In prior periods, the Corporation transferred servicing advance receivables to independent third parties in connection with the sale of MSRs. Portions of the receivables were transferred into unconsolidated securitization trusts. The Corporation retained senior interests in such receivables with a maximum loss exposure and funding obligation of $90 million and $150 million , including a funded balance of $58 million and $75 million at June 30, 2017 and December 31, 2016 , which were classified in other debt securities carried at fair value. Leveraged Lease Trusts The Corporation’s net investment in consolidated leveraged lease trusts totaled $2.4 billion and $2.6 billion at June 30, 2017 and December 31, 2016 . The trusts hold long-lived equipment such as rail cars, power generation and distribution equipment, and commercial aircraft. The Corporation structures the trusts and holds a significant residual interest. The net investment represents the Corporation’s maximum loss exposure to the trusts in the unlikely event that the leveraged lease investments become worthless. Debt issued by the leveraged lease trusts is non-recourse to the Corporation. Tax Credit Vehicles The Corporation holds investments in unconsolidated limited partnerships and similar entities that construct, own and operate affordable housing, wind and solar projects. An unrelated third party is typically the general partner or managing member and has control over the significant activities of the vehicle. The Corporation earns a return primarily through the receipt of tax credits allocated to the projects. The maximum loss exposure included in the Other VIEs table was $13.3 billion and $12.6 billion at June 30, 2017 and December 31, 2016 . The Corporation’s risk of loss is generally mitigated by policies requiring that the project qualify for the expected tax credits prior to making its investment. The Corporation's investments in affordable housing partnerships, which are reported in other assets on the Consolidated Balance Sheet, totaled $7.5 billion and $7.4 billion , including unfunded commitments to provide capital contributions of $2.7 billion and $2.7 billion at June 30, 2017 and December 31, 2016 . The unfunded commitments are expected to be paid over the next five years . The Corporation recognized tax credits and other tax benefits from investments in affordable housing partnerships of $281 million and $532 million , and reported pre-tax losses in other noninterest income of $207 million and $403 million for the three and six months ended June 30, 2017 . For the same periods in 2016 , the Corporation recognized tax credits and other tax benefits of $289 million and $482 million , and pre-tax losses of $198 million and $396 million . Tax credits are recognized as part of the Corporation's annual effective tax rate used to determine tax expense in a given quarter. Accordingly, the portion of a year's expected tax benefits recognized in any given quarter may differ from 25 percent . The Corporation may from time to time be asked to invest additional amounts to support a troubled affordable housing project. Such additional investments have not been and are not expected to be significant.

Representations and Warranties Obligations and Corporate Guarantees [Abstract]
Representations and Warranties Obligations and Corporate Guarantees	Representations and Warranties Obligations and Corporate Guarantees For information on representations and warranties obligations and corporate guarantees and related settlement actions, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K . Unresolved Repurchase Claims Unresolved representations and warranties repurchase claims represent the notional amount of repurchase claims made by counterparties, typically the outstanding principal balance or the unpaid principal balance at the time of default. In the case of first-lien mortgages, the claim amount is often significantly greater than the expected loss amount due to the benefit of collateral and, in some cases, mortgage insurance (MI) or mortgage guarantee payments. Claims received from a counterparty remain outstanding until the underlying loan is repurchased, the claim is rescinded by the counterparty, the Corporation determines that the applicable statute of limitations has expired, or representations and warranties claims with respect to the applicable trust are settled, and fully and finally released. The Corporation does not include duplicate claims in the amounts disclosed. The following table presents unresolved repurchase claims at June 30, 2017 and December 31, 2016 . The unresolved repurchase claims include only claims where the Corporation believes that the counterparty has the contractual right to submit claims. The unresolved repurchase claims predominantly relate to subprime and pay option first-lien loans and home equity loans. For more information, see Private-label Securitizations and Whole-loan Sales Experience in the MD&A of the Corporation's 2016 Annual Report on Form 10-K , as well as Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K . Unresolved Repurchase Claims by Counterparty, net of duplicate claims (Dollars in millions) June 30 December 31 By counterparty Private-label securitization trustees, whole-loan investors, including third-party securitization sponsors and other (1) $ 16,024 $ 16,685 Monolines 1,582 1,583 GSEs 7 9 Total unresolved repurchase claims by counterparty, net of duplicate claims $ 17,613 $ 18,277 (1) Includes $11.3 billion and $11.9 billion of claims based on individual file reviews and $4.7 billion and $4.8 billion of claims submitted without individual file reviews at June 30, 2017 and December 31, 2016 . During the six months ended June 30, 2017 , the Corporation received $49 million in new repurchase claims and $714 million in claims were resolved, including $640 million related to settlements. Of the remaining unresolved monoline claims, substantially all of the claims pertain to second-lien loans and are currently the subject of litigation with a single monoline insurer. There may be additional claims or file requests in the future. In addition to the unresolved repurchase claims in the Unresolved Repurchase Claims by Counterparty, net of duplicate claims table, the Corporation has received notifications from sponsors of third-party securitizations with whom the Corporation engaged in whole-loan transactions indicating that the Corporation may have indemnity obligations with respect to loans for which the Corporation has not received a repurchase request. These outstanding notifications totaled $1.3 billion at both June 30, 2017 and December 31, 2016 . There were no new notifications received during the six months ended June 30, 2017 . The presence of repurchase claims on a given trust, receipt of notices of indemnification obligations and receipt of other communications, as discussed above, are all factors that inform the Corporation’s liability for representations and warranties and the corresponding estimated range of possible loss. Private-label Securitizations and Whole-loan Sales Experience Prior to 2009, legacy companies and certain subsidiaries sold pools of first-lien residential mortgage loans and home equity loans as private-label securitizations or in the form of whole loans. For more information on private-label securitizations and whole-loan sales experience, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K . At June 30, 2017 and December 31, 2016 , the notional amount of unresolved repurchase claims submitted by private-label securitization trustees, whole-loan investors, including third-party securitization sponsors, and others was $16.0 billion and $16.7 billion . The notional amount of unresolved repurchase claims at June 30, 2017 and December 31, 2016 included $5.1 billion and $5.6 billion of claims related to loans in specific private-label securitization groups or tranches where the Corporation owns substantially all of the outstanding securities or will otherwise realize the benefit of any repurchase claims paid. The overall decrease in the notional amount of outstanding unresolved repurchase claims in the six months ended June 30, 2017 was primarily due to claims that were resolved as a result of settlements. Outstanding repurchase claims remained unresolved primarily due to (1) the level of detail, support and analysis accompanying such claims, which impact overall claim quality and, therefore, claims resolution, and (2) the lack of an established process to resolve disputes related to these claims. Liability for Representations and Warranties and Corporate Guarantees and Estimated Range of Possible Loss The liability for representations and warranties and corporate guarantees is included in accrued expenses and other liabilities on the Consolidated Balance Sheet and the related provision is included in mortgage banking income in the Consolidated Statement of Income. The Corporation’s representations and warranties liability and the corresponding estimated range of possible loss at June 30, 2017 considers, among other things, the repurchase experience implied in the settlements with BNY Mellon and other counterparties. Since the securitization trusts that were included in the settlements with BNY Mellon and other counterparties differ from other securitization trusts, the Corporation adjusts the experience implied by those prior settlements based on the characteristics of those trusts where the Corporation has a continuing possibility of timely claims in order to determine the representations and warranties liability and the corresponding estimated range of possible loss. The table below presents a rollforward of the liability for representations and warranties and corporate guarantees. Representations and Warranties and Corporate Guarantees Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2017 2016 2017 2016 Liability for representations and warranties and corporate guarantees, beginning of period $ 2,294 $ 2,812 $ 2,339 $ 11,326 Additions for new sales 1 1 2 2 Payments (1) (45 ) (107 ) (88 ) (8,664 ) Provision (benefit) (2 ) 17 (5 ) 59 Liability for representations and warranties and corporate guarantees, June 30 $ 2,248 $ 2,723 $ 2,248 $ 2,723 (1) In February 2016, the Corporation made an $8.5 billion settlement payment to BNY Mellon as part of the settlement with BNY Mellon. The representations and warranties liability represents the Corporation’s best estimate of probable incurred losses as of June 30, 2017 . However, it is reasonably possible that future representations and warranties losses may occur in excess of the amounts recorded for these exposures. The Corporation currently estimates that the range of possible loss for representations and warranties exposures could be up to $2 billion over existing accruals at June 30, 2017 . The Corporation treats claims that are time-barred as resolved and does not consider such claims in the estimated range of possible loss. The estimated range of possible loss reflects principally exposures related to loans in private-label securitization trusts. It represents a reasonably possible loss, but does not represent a probable loss, and is based on currently available information, significant judgment and a number of assumptions that are subject to change. For more information on the liability for representations and warranties exposures and the corresponding estimated range of possible loss, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2017 , and Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K .

In these transactions, the Corporation recognizes an asset at fair value, representing the securities received, and a liability, representing the obligation to return those securities. Repurchase Agreements and Securities Loaned Transactions Accounted for as Secured Borrowings The tables below present securities sold under agreements to repurchase and securities loaned by remaining contractual term to maturity and class of collateral pledged. Included in “Other” are transactions where the Corporation acts as the lender in a securities lending agreement and receives securities that can be pledged as collateral or sold. Certain agreements contain a right to substitute collateral and/or terminate the agreement prior to maturity at the option of the Corporation or the counterparty. Such agreements are included in the table below based on the remaining contractual term to maturity. At June 30, 2017 and December 31, 2016 , the Corporation had no outstanding repurchase-to-maturity transactions.

For securities loaned transactions, the Corporation receives collateral in the form of cash, letters of credit or other securities. To help ensure that the market value of the underlying collateral remains sufficient, collateral is generally valued daily, and the Corporation may be required to deposit additional collateral or may receive or return collateral pledged when appropriate. Repurchase agreements and securities loaned transactions are generally either overnight, continuous (i.e., no stated term) or short-term. The Corporation manages liquidity risks related to these agreements by sourcing funding from a diverse group of counterparties, providing a range of securities collateral and pursuing longer durations, when appropriate.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, the Corporation enters into a number of off-balance sheet commitments. These commitments expose the Corporation to varying degrees of credit and market risk and are subject to the same credit and market risk limitation reviews as those instruments recorded on the Consolidated Balance Sheet. For more information on commitments and contingencies, see Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. Credit Extension Commitments The Corporation enters into commitments to extend credit such as loan commitments, standby letters of credit (SBLCs) and commercial letters of credit to meet the financing needs of its customers. The table below includes the notional amount of unfunded legally binding lending commitments net of amounts distributed (e.g., syndicated or participated) to other financial institutions. The distributed amounts were $11.6 billion and $12.1 billion at June 30, 2017 and December 31, 2016 . At June 30, 2017 , the carrying value of these commitments, excluding commitments accounted for under the fair value option, was $775 million , including deferred revenue of $18 million and a reserve for unfunded lending commitments of $757 million . At December 31, 2016 , the comparable amounts were $779 million , $17 million and $762 million , respectively. The carrying value of these commitments is classified in accrued expenses and other liabilities on the Consolidated Balance Sheet. The table below also includes the notional amount of commitments of $4.5 billion and $7.0 billion at June 30, 2017 and December 31, 2016 that are accounted for under the fair value option. However, the table below excludes cumulative net fair value of $138 million and $173 million on these commitments, which is classified in accrued expenses and other liabilities. For more information regarding the Corporation’s loan commitments accounted for under the fair value option, see Note 15 – Fair Value Option . Credit Extension Commitments June 30, 2017 (Dollars in millions) Expire in One Expire After One Expire After Three Expire After Five Total Notional amount of credit extension commitments Loan commitments $ 75,829 $ 135,276 $ 147,581 $ 21,895 $ 380,581 Home equity lines of credit 8,184 6,864 2,186 28,581 45,815 Standby letters of credit and financial guarantees (1) 21,287 10,535 2,743 1,328 35,893 Letters of credit 1,371 108 76 58 1,613 Legally binding commitments 106,671 152,783 152,586 51,862 463,902 Credit card lines (2) 360,848 — — — 360,848 Total credit extension commitments $ 467,519 $ 152,783 $ 152,586 $ 51,862 $ 824,750 December 31, 2016 Notional amount of credit extension commitments Loan commitments $ 82,609 $ 133,063 $ 152,854 $ 22,129 $ 390,655 Home equity lines of credit 8,806 10,701 2,644 25,050 47,201 Standby letters of credit and financial guarantees (1) 19,165 10,754 3,225 1,027 34,171 Letters of credit 1,285 103 114 53 1,555 Legally binding commitments 111,865 154,621 158,837 48,259 473,582 Credit card lines (2) 377,773 — — — 377,773 Total credit extension commitments $ 489,638 $ 154,621 $ 158,837 $ 48,259 $ 851,355 (1) The notional amounts of SBLCs and financial guarantees classified as investment grade and non-investment grade based on the credit quality of the underlying reference name within the instrument were $27.5 billion and $8.0 billion at June 30, 2017 , and $25.5 billion and $8.3 billion at December 31, 2016 . Amounts in the table include consumer SBLCs of $397 million and $376 million at June 30, 2017 and December 31, 2016 . (2) Includes business card unused lines of credit. Legally binding commitments to extend credit generally have specified rates and maturities. Certain of these commitments have adverse change clauses that help to protect the Corporation against deterioration in the borrower’s ability to pay. Other Commitments At June 30, 2017 and December 31, 2016 , the Corporation had commitments to purchase loans (e.g., residential mortgage and commercial real estate) of $598 million and $767 million , and commitments to purchase commercial loans of $2.7 billion and $636 million , which upon settlement will be included in loans or LHFS. At June 30, 2017 and December 31, 2016 , the Corporation had commitments to purchase commodities, primarily liquefied natural gas of $1.6 billion and $1.9 billion , which upon settlement will be included in trading account assets. At June 30, 2017 and December 31, 2016 , the Corporation had commitments to enter into resale and forward-dated resale and securities borrowing agreements of $74.2 billion and $48.9 billion , and commitments to enter into forward-dated repurchase and securities lending agreements of $41.3 billion and $24.4 billion . These commitments expire primarily within the next 12 months. The Corporation has entered into agreements to purchase retail automotive loans from certain auto loan originators. These agreements provide for stated purchase amounts and contain cancellation provisions that allow the Corporation to terminate its commitment to purchase at any time, with a minimum notification period. At June 30, 2017 and December 31, 2016 , the Corporation’s maximum purchase commitment was $345 million and $475 million . In addition, the Corporation has a commitment to originate or purchase auto loans and leases from a strategic partner up to $1.5 billion for the remainder of 2017 , with this commitment expiring on December 31, 2017. The Corporation is a party to operating leases for certain of its premises and equipment. Commitments under these leases are approximately $1.2 billion , $2.2 billion , $2.0 billion , $1.8 billion and $1.5 billion for the remainder of 2017 and the years through 2021 , respectively, and $5.7 billion in the aggregate for all years thereafter. Other Guarantees Bank-owned Life Insurance Book Value Protection The Corporation sells products that offer book value protection to insurance carriers who offer group life insurance policies to corporations, primarily banks. At June 30, 2017 and December 31, 2016 , the notional amount of these guarantees, which are recorded as derivatives totaled $14.0 billion and $13.9 billion . At both June 30, 2017 and December 31, 2016 , the Corporation’s maximum exposure related to these guarantees totaled $3.2 billion , with estimated maturity dates between 2031 and 2039. The net fair value including the fee receivable associated with these guarantees was $2 million and $4 million at June 30, 2017 and December 31, 2016 , and reflects the probability of surrender as well as the multiple structural protection features in the contracts. Merchant Services In accordance with credit and debit card association rules, the Corporation sponsors merchant processing servicers that process credit and debit card transactions on behalf of various merchants. In connection with these services, a liability may arise in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder’s favor. If the merchant defaults on its obligation to reimburse the cardholder, the cardholder, through its issuing bank, generally has until six months after the date of the transaction to present a chargeback to the merchant processor, which is primarily liable for any losses on covered transactions. However, if the merchant processor fails to meet its obligation to reimburse the cardholder for disputed transactions, then the Corporation, as the sponsor, could be held liable for the disputed amount. For the three and six months ended June 30, 2017 , the sponsored entities processed and settled $204.6 billion and $391.4 billion of transactions and recorded losses of $8 million and $15 million . For the three and six months ended June 30, 2016 , the sponsored entities processed and settled $178.4 billion and $337.8 billion of transactions and recorded losses of $8 million and $14 million . A significant portion of this activity was processed by a joint venture in which the Corporation holds a 49 percent ownership, and is recorded in other assets on the Consolidated Balance Sheet and in All Other . At both June 30, 2017 and December 31, 2016 , the carrying value of the Corporation's investment in the merchant services joint venture was $2.9 billion . As of June 30, 2017 and December 31, 2016 , the maximum potential exposure for sponsored transactions totaled $323.8 billion and $325.7 billion . However, the Corporation believes that the maximum potential exposure is not representative of the actual potential loss exposure and does not expect to make material payments in connection with these guarantees. Other Guarantees The Corporation has entered into additional guarantee agreements and commitments, including sold risk participation swaps, liquidity facilities, lease-end obligation agreements, partial credit guarantees on certain leases, real estate joint venture guarantees, divested business commitments and sold put options that require gross settlement. The maximum potential future payment under these agreements was approximately $6.6 billion and $6.7 billion at June 30, 2017 and December 31, 2016 . The estimated maturity dates of these obligations extend up to 2040. The Corporation has made no material payments under these guarantees. In the normal course of business, the Corporation periodically guarantees the obligations of its affiliates in a variety of transactions including ISDA-related transactions and non-ISDA related transactions such as commodities trading, repurchase agreements, prime brokerage agreements and other transactions. Payment Protection Insurance Claims Matter On June 1, 2017, the Corporation completed the sale of its non-U.S. consumer credit card business. Included in the calculation of the gain on sale, the Corporation recorded an obligation to indemnify the purchaser for substantially all PPI exposure above reserves assumed by the purchaser. Litigation and Regulatory Matters The following supplements the disclosure in Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K and in Note 10 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2017 (the prior commitments and contingencies disclosure). In the ordinary course of business, the Corporation and its subsidiaries are routinely defendants in or parties to many pending and threatened legal, regulatory and governmental actions and proceedings. In view of the inherent difficulty of predicting the outcome of such matters, particularly where the claimants seek very large or indeterminate damages or where the matters present novel legal theories or involve a large number of parties, the Corporation generally cannot predict what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines or penalties related to each pending matter may be. In accordance with applicable accounting guidance, the Corporation establishes an accrued liability when those matters present loss contingencies that are both probable and estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. As a matter develops, the Corporation, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether such matter presents a loss contingency that is probable and estimable. Once the loss contingency is deemed to be both probable and estimable, the Corporation will establish an accrued liability and record a corresponding amount of litigation-related expense. The Corporation continues to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. Excluding expenses of internal and external legal service providers, litigation-related expense of $192 million and $466 million was recognized for the three and six months ended June 30, 2017 compared to $270 million and $658 million for the same periods in 2016. For a limited number of the matters disclosed in this Note, and in the prior commitments and contingencies disclosure, for which a loss, whether in excess of a related accrued liability or where there is no accrued liability, is reasonably possible in future periods, the Corporation is able to estimate a range of possible loss. In determining whether it is possible to estimate a range of possible loss, the Corporation reviews and evaluates its matters on an ongoing basis, in conjunction with any outside counsel handling the matter, in light of potentially relevant factual and legal developments. In cases in which the Corporation possesses sufficient appropriate information to estimate a range of possible loss, that estimate is aggregated and disclosed below. There may be other disclosed matters for which a loss is probable or reasonably possible but such an estimate of the range of possible loss may not be possible. For those matters where an estimate of the range of possible loss is possible, management currently estimates the aggregate range of possible loss is $0 to $1.5 billion in excess of the accrued liability (if any) related to those matters. This estimated range of possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions, and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate. Therefore, this estimated range of possible loss represents what the Corporation believes to be an estimate of possible loss only for certain matters meeting these criteria. It does not represent the Corporation’s maximum loss exposure. Information is provided below, or in the prior commitments and contingencies disclosure, regarding the nature of all of these contingencies and, where specified, the amount of the claim associated with these loss contingencies. Based on current knowledge, management does not believe that loss contingencies arising from pending matters, including the matters described herein and in the prior commitments and contingencies disclosure, will have a material adverse effect on the consolidated financial position or liquidity of the Corporation. However, in light of the inherent uncertainties involved in these matters, some of which are beyond the Corporation’s control, and the very 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 Corporation’s results of operations or liquidity for any particular reporting period. Bond Insurance Litigation Ambac v. Countrywide l On May 16, 2017, the First Department issued its decision on the parties' summary judgment cross-appeals. Among other things, the First Department reversed on the applicability of New York insurance law to Ambac's common-law fraud claim, ruling that Ambac must prove all of the elements of its fraudulent inducement claim, including justifiable reliance and loss causation; reversed as to Ambac's remedy for its breach of contract claims, finding that Ambac's sole remedy is the repurchase protocol of cure, repurchases, or substitution of any materially defective loan; affirmed the trial court's ruling that Ambac's compensatory damages claim was an impermissible request for rescissory damages; reversed the dismissal of Ambac's claim for reimbursement of claims payments, but affirmed the dismissal of Ambac's claim for reimbursements of attorneys' fees; and reversed as to the meaning of specific representations and warranties, ruling that disputed issues of fact precluded summary judgment. On July 25, 2017, the First Department granted Ambac's motion for leave to appeal to the Court of Appeals. Separately, the First Department reversed summary judgment for Ambac on the continuity-of-ownership element of its New York law de facto merger claim and remanded for fact issues, while concluding that no continuity of ownership exists where the asset-seller receives fair value, and that the fair value element requires the asset-seller's shareholders to acquire their shares in the buyer as an element of the asset purchase transaction; reversed and dismissed Ambac's claim that the Corporation impliedly assumed Countrywide's liabilities; affirmed the ruling that fact issues prelude summary judgment on Ambac's alter-ego claim; and ruled that New York law applies to the de facto merger determination. Ambac v. Countrywide III On June 30, 2017, the Wisconsin Supreme Court reversed the decision of the Wisconsin Court of Appeals and held that Countrywide did not consent to the jurisdiction of the Wisconsin courts by registering to do business in Wisconsin. It remanded the case to the Court of Appeals for further consideration of whether specific jurisdiction exists for this matter. U.S. Bank -- Harborview Repurchase Litigation On June 12, 2017, U.S. Bank filed an Amended Petition in the Minnesota Action informing the court that, while a vote of the certificate-holders supports acceptance of the proposed settlement, an expert engaged by U.S. Bank concluded that the proposed settlement amount fell below what the expert considers to be a reasonable settlement range and recommended that U.S. Bank reject the proposed settlement. As a result, the Amended Petition seeks authorization from the Minnesota court to reject the proposed settlement and to continue the litigation in New York state court.

On June 28, 2017, following the Federal Reserve's non-objection to the Corporation’s 2017 Comprehensive Capital Analysis and Review (CCAR) capital plan, the Board of Directors authorized the repurchase of $12.9 billion in common stock from July 1, 2017 through June 30, 2018, including approximately $900 million to offset the effect of equity-based compensation plans during the same period. The common stock repurchase authorization includes both common stock and warrants. The Corporation’s 2017 capital plan also included a request to increase the quarterly common stock dividend from $0.075 per share to $0.12 per share. On January 13, 2017, the Corporation announced a plan to repurchase $1.8 billion of common stock during the first half of 2017, to which the Federal Reserve did not object, in addition to the previously announced repurchases associated with the 2016 CCAR capital plan. During the three and six months ended June 30, 2017 , the Corporation repurchased and retired 96 million and 211 million shares of common stock, which reduced shareholders' equity by $2.2 billion and $5.0 billion , respectively. The Corporation has warrants outstanding and exercisable to purchase 122 million shares of its common stock expiring on October 28, 2018, and warrants outstanding and exercisable to purchase 150 million shares of common stock expiring on January 16, 2019. These warrants were originally issued in connection with preferred stock issuances to the U.S. Department of the Treasury in 2009 and 2008, and are listed on the New York Stock Exchange. The exercise price of the warrants expiring on January 16, 2019 is subject to continued adjustment each time the quarterly cash dividend is in excess of $0.01 per common share to compensate the holders of the warrants for dilution resulting from an increased dividend. As a result of the Corporation’s second-quarter 2017 dividend of $0.075 per common share, the exercise price of the warrants expiring on January 16, 2019 was adjusted to $12.867 per share. The warrants expiring on October 28, 2018, which have an exercise price of $30.79 per share, also contain this anti-dilution provision except the adjustment is triggered only when the Corporation declares quarterly dividends at a level greater than $0.32 per common share. During the six months ended June 30, 2017 , in connection with employee stock plans, the Corporation issued approximately 60 million shares and repurchased approximately 24 million shares of its common stock to satisfy tax withholding obligations. At June 30, 2017 , the Corporation had reserved 1.6 billion unissued shares of common stock for future issuances under employee stock plans, common stock warrants, convertible notes and preferred stock. Preferred Stock During the three months ended March 31, 2017 and June 30, 2017 , the Corporation declared $502 million and $361 million of cash dividends on preferred stock, or a total of $863 million for the six months ended June 30, 2017 . There were no issuances of preferred stock during the six months ended June 30, 2017 .

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share The calculation of earnings per common share (EPS) and diluted EPS for the three and six months ended June 30, 2017 and 2016 is presented below. For more information on the calculation of EPS, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K . Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions, except per share information; shares in thousands) 2017 2016 2017 2016 Earnings per common share Net income $ 5,269 $ 4,783 $ 10,125 $ 8,255 Preferred stock dividends (361 ) (361 ) (863 ) (818 ) Net income applicable to common shareholders $ 4,908 $ 4,422 $ 9,262 $ 7,437 Average common shares issued and outstanding 10,013,503 10,328,424 10,056,111 10,308,241 Earnings per common share $ 0.49 $ 0.43 $ 0.92 $ 0.72 Diluted earnings per common share Net income applicable to common shareholders $ 4,908 $ 4,422 $ 9,262 $ 7,437 Add preferred stock dividends due to assumed conversions 75 75 150 150 Net income allocated to common shareholders $ 4,983 $ 4,497 $ 9,412 $ 7,587 Average common shares issued and outstanding 10,013,503 10,328,424 10,056,111 10,308,241 Dilutive potential common shares (1) 808,566 730,743 812,320 771,698 Total diluted average common shares issued and outstanding 10,822,069 11,059,167 10,868,431 11,079,939 Diluted earnings per common share $ 0.46 $ 0.41 $ 0.87 $ 0.68 (1) Includes incremental dilutive shares from restricted stock units, restricted stock and warrants. The Corporation previously issued a warrant to purchase 700 million shares of the Corporation’s common stock to the holder of the Series T Preferred Stock. The warrant may be exercised, at the option of the holder, through tendering the Series T Preferred Stock or paying cash. For both the three and six months ended June 30, 2017 and 2016 , the 700 million average dilutive potential common shares were included in the diluted share count under the “if-converted” method. For both the three and six months ended June 30, 2017 and 2016 , 62 million average dilutive potential common shares associated with the Series L Preferred Stock were not included in the diluted share count because the result would have been antidilutive under the “if-converted” method. For the three and six months ended June 30, 2017 , average options to purchase 18 million and 24 million shares of common stock were outstanding but not included in the computation of EPS because the result would have been antidilutive under the treasury stock method compared to 42 million and 48 million for the same periods in 2016 . For both the three and six months ended June 30, 2017 and 2016 , average warrants to purchase 122 million shares of common stock were outstanding but not included in the computation of EPS because the result would have been antidilutive under the treasury stock method, and average warrants to purchase 150 million shares of common stock were included in the diluted EPS calculation under the treasury stock method.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Under applicable accounting standards, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Corporation determines the fair values of its financial instruments under applicable accounting standards and conducts a review of its fair value hierarchy classifications on a quarterly basis. Transfers into or out of fair value hierarchy classifications are considered to be effective as of the beginning of the quarter in which they occur. During the six months ended June 30, 2017 , there were no changes to valuation approaches or techniques that had, or are expected to have, a material impact on the Corporation’s consolidated financial position or results of operations. For more information regarding the fair value hierarchy and how the Corporation measures fair value and valuation processes and techniques see Note 1 – Summary of Significant Accounting Principles and Note 20 – Fair Value Measurements to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K . The Corporation accounts for certain financial instruments under the fair value option. For additional information, see Note 15 – Fair Value Option . Recurring Fair Value Assets and liabilities carried at fair value on a recurring basis at June 30, 2017 and December 31, 2016 , including financial instruments which the Corporation accounts for under the fair value option, are summarized in the following tables.

For assets, increase (decrease) to Level 3 and for liabilities, (increase) decrease to Level 3. (2) Includes gains/losses reported in earnings in the following income statement line items: Trading account assets/liabilities - trading account profits (losses); Net derivative assets - primarily trading account profits (losses) and mortgage banking income (loss); MSRs - primarily mortgage banking income (loss); Long-term debt - primarily trading account profits (losses). For MSRs, the amounts reflect the changes in modeled MSR fair value due to observed changes in interest rates, volatility, spreads and the shape of the forward swap curve, and periodic adjustments to the valuation model to reflect changes in the modeled relationships between inputs and projected cash flows, as well as changes in cash flow assumptions including cost to service. (3) Includes gains/losses in OCI related to unrealized gains/losses on AFS securities, foreign currency translation adjustments and the impact of changes in the Corporation’s credit spreads on long-term debt accounted for under the fair value option. For additional information, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. (4) Net derivatives include derivative assets of $4.0 billion and derivative liabilities of $5.8 billion . (5) Amounts represent instruments that are accounted for under the fair value option. (6) Issuances represent loan originations and MSRs recognized following securitizations or whole-loan sales. (7) Settlements represent the net change in fair value of the MSR asset due to the recognition of modeled cash flows and the passage of time. Significant transfers into Level 3, primarily due to decreased price observability, during the three months ended June 30, 2017 included $318 million of trading account assets, $100 million of LHFS and $108 million of long-term debt. Transfers occur on a regular basis for long-term debt instruments due to changes in the impact of unobservable inputs on the value of the embedded derivative in relation to the instrument as a whole. Significant transfers out of Level 3, primarily due to increased price observability, during the three months ended June 30, 2017 included $428 million of trading account assets and $157 million of federal funds purchased and securities loaned or sold under agreements to repurchase.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Financial instruments are classified into three levels based on the established fair value hierarchy. For additional information, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The following disclosures include financial instruments that are not carried at fair value or only a portion of the ending balance at June 30, 2017 and December 31, 2016 is carried at fair value on the Consolidated Balance Sheet. For more information on these financial instruments and their valuation methodologies, see Note 20 – Fair Value Measurements and Note 22 – Fair Value of Financial Instruments to the Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. Fair Value of Financial Instruments The carrying values and fair values by fair value hierarchy of certain financial instruments where only a portion of the ending balance was carried at fair value at June 30, 2017 and December 31, 2016 are presented in the following table. Fair Value of Financial Instruments June 30, 2017 Fair Value (Dollars in millions) Carrying Value Level 2 Level 3 Total Financial assets Loans $ 884,114 $ 64,888 $ 827,122 $ 892,010 Loans held-for-sale 5,882 4,867 1,015 5,882 Financial liabilities Deposits 1,262,980 1,263,010 — 1,263,010 Long-term debt 223,923 229,134 1,646 230,780 December 31, 2016 Financial assets Loans $ 873,209 $ 71,793 $ 815,329 $ 887,122 Loans held-for-sale 9,066 8,082 984 9,066 Financial liabilities Deposits 1,260,934 1,261,086 — 1,261,086 Long-term debt 216,823 220,071 1,514 221,585 Commercial Unfunded Lending Commitments Fair values were generally determined using a discounted cash flow valuation approach which is applied using market-based credit default swaps or internally developed benchmark credit curves. The Corporation accounts for certain loan commitments under the fair value option. The carrying values and fair values of the Corporation’s commercial unfunded lending commitments were $895 million and $4.2 billion at June 30, 2017 , and $937 million and $4.9 billion at December 31, 2016 . Commercial unfunded lending commitments are primarily classified as Level 3. The carrying value of these commitments is classified in accrued expenses and other liabilities. The Corporation does not estimate the fair values of consumer unfunded lending commitments because, in many instances, the Corporation can reduce or cancel these commitments by providing notice to the borrower. For more information on commitments, see Note 10 – Commitments and Contingencies .

Summary of Significant Accoun25

Summary of Significant Accounting Principles (Policies)	6 Months Ended
	Jun. 30, 2017
Accounting Policies [Abstract]
Consolidation	The Consolidated Financial Statements include the accounts of the Corporation and its majority-owned subsidiaries and those variable interest entities (VIEs) where the Corporation is the primary beneficiary. Intercompany accounts and transactions have been eliminated. Results of operations of acquired companies are included from the dates of acquisition and for VIEs, from the dates that the Corporation became the primary beneficiary. Assets held in an agency or fiduciary capacity are not included in the Consolidated Financial Statements. The Corporation accounts for investments in companies for which it owns a voting interest and for which it has the ability to exercise significant influence over operating and financing decisions using the equity method of accounting. These investments are included in other assets. Equity method investments are subject to impairment testing, and the Corporation’s proportionate share of income or loss is included in other income.
Basis of Accounting	The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect reported amounts and disclosures. Realized results could differ from those estimates and assumptions. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation's 2016 Annual Report on Form 10-K. The nature of the Corporation's business is such that the results of any interim period are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period results have been made. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission (SEC). Certain prior-period amounts have been reclassified to conform to current period presentation.
New Accounting Pronouncements	Accounting for Financial Instruments -- Credit Losses The Financial Accounting Standards Board (FASB) issued a new accounting standard effective on January 1, 2020, with early adoption permitted on January 1, 2019, that will require the earlier recognition of credit losses on loans and other financial instruments based on an expected loss model, replacing the incurred loss model that is currently in use. The standard also requires expanded credit quality disclosures, including credit quality indicators disaggregated by vintage. The Corporation is in the process of identifying and implementing required changes to loan loss estimation models and processes and evaluating the impact of this new accounting standard, which at the date of adoption is expected to increase the allowance for credit losses with a resulting negative adjustment to retained earnings. Revenue Recognition The FASB issued a new accounting standard effective on January 1, 2018 for recognizing revenue from contracts with customers. While the new standard does not apply to revenue associated with loans or securities, the Corporation has identified the customer contracts within the scope of the new standard and is assessing the related revenues to determine if any accounting or internal control changes will be required for the new provisions. The timing of the Corporation’s revenue recognition is not expected to materially change. The classification of certain contract costs continues to be evaluated, and the final interpretation may impact the presentation of certain contract costs. Overall, the Corporation does not expect the new standard to have a material impact on its consolidated financial position, results of operations or disclosures in the Notes to the Consolidated Financial Statements. Lease Accounting The FASB issued a new accounting standard effective on January 1, 2019 that requires substantially all leases to be recorded as assets and liabilities on the balance sheet. This new accounting standard uses a modified retrospective transition that will be applied to all prior periods presented. The Corporation is in the process of reviewing its existing lease portfolios, as well as other service contracts for embedded leases, to evaluate the impact of the new accounting standard on the financial statements, as well as the impact to regulatory capital and risk-weighted assets. The effect of the adoption will depend on its lease portfolio at the time of transition; however, the Corporation does not expect the new accounting standard to have a material impact on its consolidated financial position, results of operations or disclosures in the Notes to the Consolidated Financial Statements. Recognition and Measurement of Financial Assets and Financial Liabilities The FASB issued a new accounting standard effective on January 1, 2018, with early adoption permitted for the provisions related to debit valuation adjustments (DVA), on recognition and measurement of financial instruments, including certain equity investments and financial liabilities recorded at fair value under the fair value option. In 2015, the Corporation early adopted, retrospective to January 1, 2015, the provisions of this new accounting standard related to DVA on financial liabilities accounted for under the fair value option. The Corporation does not expect the remaining provisions of this new accounting standard to have a material impact on its consolidated financial position, results of operations or disclosures in the Notes to the Consolidated Financial Statements.

Derivative [Line Items]
Schedule of Derivative Instruments in Statement of Financial Position, Fair Value	The following table summarizes information related to fair value hedges for the three and six months ended June 30, 2017 and 2016 , including hedges of interest rate risk on long-term debt that were acquired as part of a business combination and redesignated at that time. At redesignation, the fair value of the derivatives was positive. As the derivatives mature, the fair value will approach zero. As a result, ineffectiveness will occur and the fair value changes in the derivatives and the long-term debt being hedged may be directionally the same in certain scenarios. Based on a regression analysis, the derivatives continue to be highly effective at offsetting changes in the fair value of the long-term debt attributable to interest rate risk. Derivatives Designated as Fair Value Hedges Gains (Losses) Three Months Ended June 30, 2017 Six Months Ended June 30, 2017 (Dollars in millions) Derivative Hedged Hedge Derivative Hedged Item Hedge Ineffectiveness Interest rate risk on long-term debt (1) $ 272 $ (422 ) $ (150 ) $ (478 ) $ 144 $ (334 ) Interest rate and foreign currency risk on long-term debt (1) 901 (877 ) 24 1,024 (1,010 ) 14 Interest rate risk on available-for-sale securities (2) (80 ) 70 (10 ) (63 ) 33 (30 ) Price risk on commodity inventory (3) 2 (1 ) 1 8 (7 ) 1 Total $ 1,095 $ (1,230 ) $ (135 ) $ 491 $ (840 ) $ (349 ) Three Months Ended June 30, 2016 Six Months Ended June 30, 2016 Interest rate risk on long-term debt (1) $ 1,263 $ (1,380 ) $ (117 ) $ 3,924 $ (4,234 ) $ (310 ) Interest rate and foreign currency risk on long-term debt (1) (495 ) 487 (8 ) 344 (359 ) (15 ) Interest rate risk on available-for-sale securities (2) (215 ) 198 (17 ) (366 ) 330 (36 ) Price risk on commodity inventory (3) (8 ) 8 — (6 ) 6 — Total $ 545 $ (687 ) $ (142 ) $ 3,896 $ (4,257 ) $ (361 ) (1) Amounts are recorded in interest expense on long-term debt and in other income.

Cash Flow and Net Investment Hedges	The table below summarizes certain information related to cash flow hedges and net investment hedges for the three and six months ended June 30, 2017 and 2016 . Of the $763 million after-tax net loss ( $1.2 billion pre-tax) on derivatives in accumulated other comprehensive income (OCI) at June 30, 2017 , $141 million after-tax ( $226 million pre-tax) is expected to be reclassified into earnings in the next 12 months. These net losses reclassified into earnings are expected to primarily reduce net interest income related to the respective hedged items. Amounts related to price risk on restricted stock awards reclassified from accumulated OCI are recorded in personnel expense. For terminated cash flow hedges, the time period over which the majority of the forecasted transactions are hedged is approximately seven years , with a maximum length of time for certain forecasted transactions of 19 years .

Accretable Yield Activity	The table below shows activity for the accretable yield on PCI loans, which include the Countrywide Financial Corporation (Countrywide) portfolio and loans repurchased in connection with the 2013 settlement with FNMA. The amount of accretable yield is affected by changes in credit outlooks, including metrics such as default rates and loss severities, prepayment speeds, which can change the amount and period of time over which interest payments are expected to be received, and the interest rates on variable rate loans. The reclassifications from nonaccretable difference in the three and six months ended June 30, 2017 were primarily due to an increase in the expected principal and interest cash flows due to lower default estimates.
