Summary of Significant Accounti

Summary of Significant Accounting Principles	3 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 requires management to make estimates and assumptions that affect reported amounts and disclosures. Realized results could materially 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 2018 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. Accounting Standards Issued and Not Yet Adopted Accounting for Financial Instruments -- Credit Losses The Financial Accounting Standards Board issued a new accounting standard that will be effective for the Corporation on January 1, 2020. The Standard replaces the existing measurement of the allowance for credit losses that is based on management’s best estimate of probable incurred credit losses inherent in the Corporation’s lending activities with management’s best estimate of lifetime expected credit losses inherent in the Corporation’s financial assets that are recognized at amortized cost. The lifetime expected credit losses will be determined using macroeconomic forecast assumptions and management judgments applicable to and through the expected life of the portfolios. The Standard will also expand credit quality disclosures. While the Standard changes the measurement of the allowance for credit losses, it does not change the Corporation’s credit risk of its lending portfolios or the ultimate losses in those portfolios. The review and validation of the models and methodologies to be used in the credit loss estimation are in process and expected to be completed during 2019. The Corporation expects that, based on current expectations of future economic conditions, upon the adoption of the Standard, the Corporation’s allowance for credit losses may increase by up to 20 percent from its allowance for credit losses as of March 31, 2019 , as disclosed herein, with a large portion of that increase being in the U.S. credit card portfolio. The ultimate impact will depend on the characteristics of the Corporation’s portfolios as well as the macroeconomic conditions and forecasts upon adoption, the validation of models and methodologies, and other management judgments. New Accounting Standards Lease Accounting On January 1, 2019, the Corporation adopted the new accounting standards that require lessees to recognize operating leases on the Consolidated Balance Sheet as right-of-use assets and lease liabilities based on the value of the discounted future lease payments. Lessor accounting is largely unchanged. Expanded disclosures about the nature and terms of lease agreements are required prospectively and are included in Note 9 – Leases . The Corporation elected to retain prior determinations of whether an existing contract contains a lease and how the lease should be classified. The Corporation elected to recognize leases existing on January 1, 2019 through a cumulative-effect adjustment which increased retained earnings by $165 million , with no adjustment to prior periods presented. Upon adoption, the Corporation also recognized right-of-use assets and lease liabilities of $9.7 billion . Adoption of the standard did not have a significant effect on the Corporation’s regulatory capital measures. Lease Accounting Principles Lessor Arrangements The Corporation provides equipment financing to its customers through a variety of lessor arrangements. Direct financing leases and sales-type leases are carried at the aggregate of lease payments receivable plus the estimated residual value of the leased property less unearned income, which is accreted to interest income over the lease terms using methods that approximate the interest method. Operating lease income is recognized on a straight-line basis. Leases generally do not contain non-lease components. Lessee Arrangements Substantially all of the Corporation’s lessee arrangements are operating leases. Under these arrangements, the Corporation records right-of-use assets and lease liabilities at lease commencement. Right-of-use assets are reported in other assets on the Consolidated Balance Sheet, and the related lease liabilities are reported in accrued expenses and other liabilities. All leases are recorded on the Consolidated Balance Sheet except for leases with an initial term less than 12 months for which the Corporation made the short-term lease election. Lease expense is recognized on a straight-line basis over the lease term and is recorded in occupancy and equipment expense in the Consolidated Statement of Income.

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. For additional information, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . The following table presents derivative instruments included in derivative assets and liabilities on the Consolidated Balance Sheet at March 31, 2019 and December 31, 2018 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 include reducing the balance for counterparty netting and cash collateral received or paid.

OTC-cleared derivatives include bilateral transactions between the Corporation and a counterparty where the transaction is cleared through a clearinghouse. Exchange-traded derivatives include listed options transacted on an exchange. (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) 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 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . Derivatives Designated as Accounting Hedges The Corporation uses various types of interest rate and foreign exchange derivative contracts to protect against changes in the fair value of its assets and liabilities due to fluctuations in interest rates and exchange rates (fair value hedges). The Corporation also uses these types of contracts 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 table below summarizes information related to fair value hedges for the three months ended March 31, 2019 and 2018 . Gains and Losses on Derivatives Designated as Fair Value Hedges Three Months Ended March 31 2019 2018 (Dollars in millions) Derivative Hedged Item Derivative Hedged Item Interest rate risk on long-term debt (1) $ 1,913 $ (1,929 ) $ (2,305 ) $ 2,236 Interest rate and foreign currency risk on long-term debt (2) 57 (48 ) 322 (346 ) Interest rate risk on available-for-sale securities (3) (45 ) 43 (31 ) 30 Total $ 1,925 $ (1,934 ) $ (2,014 ) $ 1,920 (1) Amounts are recorded in interest expense in the Consolidated Statement of Income. (2) For the three months ended March 31, 2019 and 2018 , the derivative amount includes gains of $170 million and losses of $64 million in interest expense and losses of $121 million and gains of $433 million in other income. Line item totals are in the Consolidated Statement of Income. (3) Amounts are recorded in interest income in the Consolidated Statement of Income. The table below summarizes the carrying value of hedged assets and liabilities that are designated and qualifying in fair value hedging relationships along with the cumulative amount of fair value hedging adjustments included in the carrying value that have been recorded in the current hedging relationships. These fair value hedging adjustments are open basis adjustments that are not subject to amortization as long as the hedging relationship remains designated. Designated Fair Value Hedged Assets (Liabilities) March 31, 2019 December 31, 2018 (Dollars in millions) Carrying Value Cumulative Fair Value Adjustments (1) Carrying Value Cumulative Fair Value Adjustments (1) Long-term debt $ (148,566 ) $ (4,691 ) $ (138,682 ) $ (2,117 ) Available-for-sale debt securities 1,596 4 981 (29 ) (1) For assets, increase (decrease) to carrying value and for liabilities, (increase) decrease to carrying value. At March 31, 2019 and December 31, 2018 , the cumulative fair value adjustments remaining on long-term debt and available-for-sale (AFS) debt securities from discontinued hedging relationships resulted in a decrease to the related liability of $1.7 billion and $1.6 billion and an increase (decrease) to the related asset of $2 million and $(29) million , which are being amortized over the remaining contractual life of the de-designated hedged items. Cash Flow and Net Investment Hedges The following table summarizes certain information related to cash flow hedges and net investment hedges for the three months ended March 31, 2019 and 2018 . Of the $787 million after-tax net loss ( $1.0 billion pretax) on derivatives in accumulated other comprehensive income (OCI) at March 31, 2019 , $196 million after-tax ( $258 million pretax) 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. For terminated cash flow hedges, the time period over which the majority of the forecasted transactions are hedged is approximately 4 years , with a maximum length of time for certain forecasted transactions of 17 years . Gains and Losses on Derivatives Designated as Cash Flow and Net Investment Hedges Three Months Ended March 31 2019 2018 (Dollars in millions) Gains (Losses) Recognized in Gains (Losses) in Income Gains (Losses) Recognized in Gains (Losses) in Income Cash flow hedges Interest rate risk on variable-rate assets (1) $ 254 $ (23 ) $ (428 ) $ (50 ) Price risk on certain restricted stock awards (2) — — 4 27 Total $ 254 $ (23 ) $ (424 ) $ (23 ) Net investment hedges Foreign exchange risk (3) $ 6 $ 1 $ (244 ) $ (1 ) (1) Amounts reclassified from accumulated OCI are recorded in interest income in the Consolidated Statement of Income. (2) Amounts reclassified from accumulated OCI are recorded in compensation and benefits expense in the Consolidated Statement of Income. (3) Amounts reclassified from accumulated OCI are recorded in other income in the Consolidated Statement of Income. For the three months ended March 31, 2019 and 2018, amounts excluded from effectiveness testing and recognized in other income were gains of $53 million and $4 million . Other Risk Management Derivatives Other risk management derivatives are used by the Corporation to reduce certain risk exposures by economically hedging various assets and liabilities. The gains and losses on these derivatives are recognized in other income. The table below presents gains (losses) on these derivatives for the three months ended March 31, 2019 and 2018 . These gains (losses) are largely offset by the income or expense recorded on the hedged item. Gains and Losses on Other Risk Management Derivatives Three Months Ended March 31 (Dollars in millions) 2019 2018 Interest rate risk on mortgage activities (1) $ 104 $ (135 ) Credit risk on loans (26 ) (3 ) Interest rate and foreign currency risk on ALM activities (2) 1,112 (139 ) (1) Primarily related to hedges of interest rate risk on mortgage servicing rights (MSRs) and interest rate lock commitments (IRLCs) to originate mortgage loans that will be held for sale. The net gains on IRLCs, which are not included in the table but are considered derivative instruments, were $12 million and $14 million for the three months ended March 31, 2019 and 2018 . (2) Primarily related to hedges of debt securities carried at fair value and hedges of foreign currency-denominated debt. 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. As of March 31, 2019 and December 31, 2018 , the Corporation had transferred $5.7 billion and $5.8 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 $5.6 billion and $5.8 billion at the transfer dates. At both March 31, 2019 and December 31, 2018 , the fair value of the transferred securities was $5.5 billion . 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 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . The table below, 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 months ended March 31, 2019 and 2018 . The difference between total trading account income 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 adjustment (DVA) and funding valuation adjustment (FVA) gains (losses). Global Markets results in Note 18 – Business Segment Information are presented on a fully taxable-equivalent (FTE) basis. The table below is not presented on an FTE basis.

Includes investment and brokerage services revenue of $433 million and $476 million for the three months ended March 31, 2019 and 2018 . Credit Derivatives The Corporation enters into credit derivatives primarily to facilitate client transactions and to manage credit risk exposures. Credit derivatives are classified as investment and non-investment grade based on the credit quality of the underlying referenced obligation. 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. For more information on credit derivatives, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . Credit derivative instruments where the Corporation is the seller of credit protection and their expiration at March 31, 2019 and December 31, 2018 are summarized in the following table. Credit Derivative Instruments Less than One Year One to Three Years Three to Five Years Over Five Years Total March 31, 2019 (Dollars in millions) Carrying Value Credit default swaps: Investment grade $ — $ 7 $ 188 $ 505 $ 700 Non-investment grade 174 486 757 1,311 2,728 Total 174 493 945 1,816 3,428 Total return swaps/options: Investment grade 35 — — — 35 Non-investment grade 305 17 — — 322 Total 340 17 — — 357 Total credit derivatives $ 514 $ 510 $ 945 $ 1,816 $ 3,785 Credit-related notes: Investment grade $ — $ 3 $ — $ 575 $ 578 Non-investment grade 1 — 1 1,569 1,571 Total credit-related notes $ 1 $ 3 $ 1 $ 2,144 $ 2,149 Maximum Payout/Notional Credit default swaps: Investment grade $ 52,444 $ 95,398 $ 118,377 $ 10,881 $ 277,100 Non-investment grade 21,642 31,254 41,546 11,064 105,506 Total 74,086 126,652 159,923 21,945 382,606 Total return swaps/options: Investment grade 54,991 430 60 73 55,554 Non-investment grade 17,245 436 39 65 17,785 Total 72,236 866 99 138 73,339 Total credit derivatives $ 146,322 $ 127,518 $ 160,022 $ 22,083 $ 455,945 December 31, 2018 Carrying Value Credit default swaps: Investment grade $ 2 $ 44 $ 436 $ 488 $ 970 Non-investment grade 132 636 914 1,691 3,373 Total 134 680 1,350 2,179 4,343 Total return swaps/options: Investment grade 105 — — — 105 Non-investment grade 472 21 — — 493 Total 577 21 — — 598 Total credit derivatives $ 711 $ 701 $ 1,350 $ 2,179 $ 4,941 Credit-related notes: Investment grade $ — $ — $ 4 $ 532 $ 536 Non-investment grade 1 1 1 1,500 1,503 Total credit-related notes $ 1 $ 1 $ 5 $ 2,032 $ 2,039 Maximum Payout/Notional Credit default swaps: Investment grade $ 53,758 $ 95,699 $ 95,274 $ 20,054 $ 264,785 Non-investment grade 24,297 33,881 34,530 14,426 107,134 Total 78,055 129,580 129,804 34,480 371,919 Total return swaps/options: Investment grade 60,042 822 59 72 60,995 Non-investment grade 24,524 1,649 39 70 26,282 Total 84,566 2,471 98 142 87,277 Total credit derivatives $ 162,621 $ 132,051 $ 129,902 $ 34,622 $ 459,196 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 so that certain credit risk-related losses occur within acceptable, predefined limits. Credit-related notes in the table above include investments in securities issued by collateralized debt obligation (CDO), collateralized loan obligation 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 A majority of the Corporation’s derivative contracts contain credit risk-related contingent features, primarily in the form of ISDA master netting agreements and credit support documentation that enhance the creditworthiness of these instruments compared to other obligations of the respective counterparty with whom the Corporation has transacted. These contingent features may be for the benefit of the Corporation as well as its counterparties with respect to changes in the Corporation’s creditworthiness and the mark-to-market exposure under the derivative transactions. At March 31, 2019 and December 31, 2018 , the Corporation held cash and securities collateral of $80.2 billion and $81.6 billion , and posted cash and securities collateral of $57.4 billion and $56.5 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. The amount of additional collateral required depends on the contract and is usually a fixed incremental amount and/or the market value of the exposure. For more information on credit-related contingent features and collateral, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . At March 31, 2019 , 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 $2.3 billion , including $1.1 billion for Bank of America, National Association. Some counterparties are currently able to unilaterally terminate certain contracts, or the Corporation or certain subsidiaries may be required to take other action such as find a suitable replacement or obtain a guarantee. At March 31, 2019 and December 31, 2018 , the liability recorded for these derivative contracts was not significant. The table below presents the amount of additional collateral that would have been contractually required by derivative contracts and other trading agreements at March 31, 2019 if the rating agencies had downgraded their long-term senior debt ratings for the Corporation or certain subsidiaries by one incremental notch and by an additional second incremental notch.

The Corporation had $2 million and $4 million of credit-related other-than-temporary impairment (OTTI) losses on AFS debt securities which were recognized in other income for the three months ended March 31, 2019 and 2018 . The amount of noncredit-related OTTI losses recognized in OCI was not significant for both periods presented. The cumulative OTTI credit losses recognized in income on AFS debt securities that the Corporation does not intend to sell were $122 million and $278 million at March 31, 2019 and 2018 . For more information on OTTI losses and significant assumptions used for the Corporation’s underlying collateral, see Note 4 – Securities to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . Significant assumptions used in estimating the expected cash flows for measuring credit losses on non-agency residential mortgage-backed securities (RMBS) were as follows at March 31, 2019 . Significant Assumptions Range (1) Weighted 10th Percentile (2) 90th Percentile (2) Prepayment speed 12.1 % 3.0 % 21.0 % Loss severity 20.5 8.6 38.5 Life default rate 17.3 1.2 65.6 (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 15.8 percent for prime, 16.1 percent for Alt-A and 25.3 percent for subprime at March 31, 2019 . 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 12.5 percent for prime, 16.2 percent for Alt-A and 20.6 percent for subprime at March 31, 2019 . The remaining contractual maturity distribution and yields of the Corporation’s debt securities carried at fair value and HTM debt securities at March 31, 2019 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.

(8) Total outstandings includes loans and leases pledged as collateral of $36.7 billion . The Corporation also pledged $166.1 billion of loans with no related outstanding borrowings to secure potential borrowing capacity with the Federal Reserve Bank and FHLB. 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. All other loans are generally characterized as non-core loans and represent runoff portfolios. The Corporation has entered into long-term credit protection agreements with FNMA and FHLMC on loans totaling $6.3 billion and $6.1 billion at March 31, 2019 and December 31, 2018 , 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. During the three months ended March 31, 2019 and 2018 , the Corporation sold $950 million and $825 million of consumer real estate 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 March 31, 2019 and December 31, 2018 , $197 million and $221 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 troubled debt restructurings (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 March 31, 2019 , nonperforming loans discharged in Chapter 7 bankruptcy with no change in repayment terms were $173 million of which $94 million were current on their contractual payments, while $65 million were 90 days or more past due. Of the contractually current nonperforming loans, 60 percent were discharged in Chapter 7 bankruptcy over 12 months ago, and 52 percent were discharged 24 months or more ago. The table below presents the Corporation’s nonperforming loans and leases including nonperforming TDRs, and loans accruing past due 90 days or more at March 31, 2019 and December 31, 2018 . 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 2018 Annual Report on Form 10-K .

At March 31, 2019 and December 31, 2018 , residential mortgage includes $1.2 billion and $1.4 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 $391 million and $498 million of loans on which interest is still accruing. 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. For more information on the portfolio segments and their related credit quality indicators, see Note 1 – Summary of Significant Accounting Principles and Note 5 – Outstanding Loans and Leases to the Consolidated Financial Statements of the Corporation’s 2018 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 March 31, 2019 and December 31, 2018 .

(2) Direct/indirect consumer includes $38.6 billion and $39.9 billion of securities-based lending which is overcollateralized and therefore has minimal credit risk at March 31, 2019 and December 31, 2018 . Commercial – Credit Quality Indicators (1) U.S. Commercial Non-U.S. Commercial Commercial Real Estate Commercial Financing U.S. Small Commercial (2) (Dollars in millions) March 31, 2019 Risk ratings Pass rated $ 292,401 $ 100,015 $ 60,257 $ 20,797 $ 249 Reservable criticized 7,998 1,014 958 399 27 Refreshed FICO score (3) Less than 620 277 Greater than or equal to 620 and less than 680 695 Greater than or equal to 680 and less than 740 2,081 Greater than or equal to 740 4,382 Other internal credit metrics (3, 4) 6,905 Total commercial $ 300,399 $ 101,029 $ 61,215 $ 21,196 $ 14,616 December 31, 2018 Risk ratings Pass rated $ 291,918 $ 97,916 $ 59,910 $ 22,168 $ 389 Reservable criticized 7,359 860 935 366 29 Refreshed FICO score (3) Less than 620 264 Greater than or equal to 620 and less than 680 684 Greater than or equal to 680 and less than 740 2,072 Greater than or equal to 740 4,254 Other internal credit metrics (3, 4) 6,873 Total commercial $ 299,277 $ 98,776 $ 60,845 $ 22,534 $ 14,565 (1) Excludes $5.5 billion and $3.7 billion of loans accounted for under the fair value option at March 31, 2019 and December 31, 2018 . (2) At March 31, 2019 and December 31, 2018 , U.S. small business commercial includes $726 million and $731 million of criticized business card and small business loans which are evaluated using refreshed FICO scores or internal credit metrics, including delinquency status, rather than risk ratings. At both March 31, 2019 and December 31, 2018 , 99 percent of the balances where internal credit metrics are used was current or less than 30 days past due. (3) Refreshed FICO score and other internal credit metrics are applicable only to the U.S. small business commercial portfolio. (4) 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. For additional information, see Note 1 – Summary of Significant Accounting Principles and Note 5 – Outstanding Loans and Leases to the Consolidated Financial Statements of the Corporation’s 2018 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. 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 5 – Outstanding Loans and Leases to the Consolidated Financial Statements of the Corporation’s 2018 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 $813 million were included in TDRs at March 31, 2019 , of which $173 million were classified as nonperforming and $326 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 March 31, 2019 and December 31, 2018 , remaining commitments to lend additional funds to debtors whose terms have been modified in a consumer real estate TDR were not significant. Consumer real estate foreclosed properties totaled $236 million and $244 million at March 31, 2019 and December 31, 2018 . The carrying value of consumer real estate loans, including fully-insured loans, for which formal foreclosure proceedings were in process at March 31, 2019 was $2.2 billion . During the three months ended March 31, 2019 and 2018 , the Corporation reclassified $164 million and $168 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. The reclassifications represent non-cash investing activities and, accordingly, are not reflected in the Consolidated Statement of Cash Flows. The following table provides the unpaid principal balance, carrying value and related allowance at March 31, 2019 and December 31, 2018 , and the average carrying value and interest income recognized for the three months ended March 31, 2019 and 2018 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.

The table below presents the March 31, 2019 and 2018 unpaid principal balance, carrying value, and average pre- and post-modification interest rates of consumer real estate loans that were modified in TDRs during the three months ended March 31, 2019 and 2018 . The following Consumer Real Estate portfolio segment tables include loans that were initially classified as TDRs during the period and also loans that had previously been classified as TDRs and were modified again during the period. Consumer Real Estate – TDRs Entered into During the Three Months Ended March 31, 2019 and 2018 Unpaid Principal Balance Carrying Pre-Modification Interest Rate Post-Modification Interest Rate (1) (Dollars in millions) March 31, 2019 Residential mortgage $ 135 $ 112 4.19 % 4.27 % Home equity 63 48 5.23 4.86 Total $ 198 $ 160 4.52 4.46 March 31, 2018 Residential mortgage $ 407 $ 358 4.39 % 4.36 % Home equity 207 161 4.37 4.37 Total $ 614 $ 519 4.39 4.36 (1) The post-modification interest rate reflects the interest rate applicable only to permanently completed modifications, which exclude loans that are in a trial modification period. The table below presents the March 31, 2019 and 2018 carrying value for consumer real estate loans that were modified in a TDR during the three months ended March 31, 2019 and 2018 , by type of modification.

During the three months ended March 31, 2018, this included $168 million of modifications that met the definition of a TDR related to the 2017 hurricanes. These modifications had been written down to their net realizable value less costs to sell or were fully insured as of March 31, 2018. (2) Includes loans discharged in Chapter 7 bankruptcy with no change in repayment terms that are classified as TDRs. The table below presents the carrying value of consumer real estate loans that entered into payment default during the three months ended March 31, 2019 and 2018 that were modified in a TDR during the 12 months preceding payment default. A payment default for consumer real estate TDRs is recognized when a borrower has missed three monthly payments (not necessarily consecutively) since modification.

(2) Impaired loans within the Credit Card and Other Consumer portfolio segment consist entirely of loans that have been modified in TDRs. The Corporation seeks to assist customers that are experiencing financial difficulty by modifying loans while ensuring compliance with federal and local laws and guidelines. Credit card and other consumer loan modifications generally involve reducing the interest rate on the account, placing the customer on a fixed payment plan not exceeding 60 months and canceling the customer’s available line of credit, all of which are considered TDRs. The Corporation makes loan modifications directly with borrowers for debt held only by the Corporation (internal programs). Additionally, the Corporation makes loan modifications for borrowers working with third-party renegotiation agencies that provide solutions to customers’ entire unsecured debt structures (external programs). The Corporation classifies other secured consumer loans that have been discharged in Chapter 7 bankruptcy as TDRs which are written down to collateral value and placed on nonaccrual status no later than the time of discharge. The table below provides the unpaid principal balance, carrying value and related allowance at March 31, 2019 and December 31, 2018 and the average carrying value for the three months ended March 31, 2019 and 2018 for TDRs within the Credit Card and Other Consumer portfolio segment.

Credit card and other consumer loans are deemed to be in payment default during the quarter in which a borrower misses the second of two consecutive payments. Payment defaults are one of the factors considered when projecting future cash flows in the calculation of the allowance for loan and lease losses for impaired credit card and other consumer loans. Based on historical experience, the Corporation estimates that 14 percent of new U.S. credit card TDRs and 15 percent of new direct/indirect consumer TDRs may be in payment default within 12 Impaired commercial loans include nonperforming loans and leases and TDRs (both performing and nonperforming).

U.S. small business commercial TDRs are deemed to be in payment default during the quarter in which a borrower misses the second of two consecutive payments. Payment defaults are one of the factors considered when projecting future cash flows, along with observable market prices or fair value of collateral when measuring the allowance for loan and lease losses. TDRs that were in payment default had a carrying value of $116 million and $139 million for U.S. commercial, $3 million and $18 million for commercial real estate and $3 million and $4 million for commercial lease financing at March 31, 2019 and 2018 .

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. The tables in this Note present the assets, liabilities and maximum loss exposure of consolidated and unconsolidated VIEs at March 31, 2019 and December 31, 2018 in situations where the Corporation has continuing involvement with transferred assets or if the Corporation otherwise has a variable interest in the VIE. For more information on the Corporation’s use of VIEs and related maximum loss exposure, see Note 1 – Summary of Significant Accounting Principles and Note 7 – Securitizations and Other Variable Interest Entities to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . 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 4 – Securities or Note 5 – Outstanding Loans and Leases . The Corporation did not provide financial support to consolidated or unconsolidated VIEs during the three months ended March 31, 2019 or the year ended December 31, 2018 that it was not previously contractually required to provide, nor does it intend to do so. The Corporation had liquidity commitments, including written put options and collateral value guarantees, with certain unconsolidated VIEs of $220 million and $218 million at March 31, 2019 and December 31, 2018 . First-lien Mortgage Securitizations 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 in Note 11 – Commitments and Contingencies , 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 months ended March 31, 2019 and 2018 . First-lien Mortgage Securitizations Residential Mortgage - Agency Commercial Mortgage Three Months Ended March 31 (Dollars in millions) 2019 2018 2019 2018 Proceeds from loan sales (1) $ 1,096 $ 1,655 $ 987 $ 538 Gains on securitizations (2) 7 18 17 18 Repurchases from securitization trusts (3) 244 501 — — (1) The Corporation transfers residential mortgage loans to securitizations sponsored primarily by the GSEs or Government National Mortgage Association (GNMA) in the normal course of business and primarily receives RMBS in exchange. Substantially all of these securities are classified as Level 2 within the fair value hierarchy and are sold shortly after receipt. (2) A majority of the first-lien residential 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 $8 million and $24 million , net of hedges, during the three months ended March 31, 2019 and 2018 , 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. 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 $219.5 billion and $259.7 billion at March 31, 2019 and 2018 . Servicing fee and ancillary fee income on serviced loans was $148 million and $197 million during the three months ended March 31, 2019 and 2018 . Servicing advances on serviced loans, including loans serviced for others and loans held for investment, were $3.0 billion and $3.3 billion at March 31, 2019 and December 31, 2018 . For more information on MSRs, see Note 15 – Fair Value Measurements . During the three months ended March 31, 2019 , the Corporation deconsolidated agency residential mortgage securitization trusts with total assets of $705 million . There were no significant deconsolidations during the three months ended March 31, 2018 .

For both consolidated and unconsolidated home equity loan VIEs, the maximum loss exposure excludes the reserve for representations and warranties obligations and corporate guarantees. For additional information, see Note 11 – Commitments and Contingencies . (2) At March 31, 2019 and December 31, 2018 , loans and leases in the consolidated credit card trust included $12.1 billion and $11.0 billion of seller’s interest. (3) At March 31, 2019 and December 31, 2018 , all other assets in the consolidated credit card trust included certain short-term investments and unbilled accrued interest and fees. (4) The retained senior securities were valued using quoted market prices or observable market inputs (Level 2 of the fair value hierarchy). (5) Total assets of VIEs includes loans the Corporation transferred with which it has continuing involvement, which may include servicing the loan. Home Equity Loans The Corporation retains interests, primarily senior securities, in home equity securitization trusts to which it transferred home equity loans. 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 portion of the home equity lines of credit, 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 subordinate interests in accrued interest and fees on the securitized receivables and cash reserve accounts. During the three months ended March 31, 2018 , there were $1.6 billion of new senior debt securities issued to third-party investors from the credit card securitization trust. None were issued in the three months ended March 31, 2019 . At March 31, 2019 and December 31, 2018 , the Corporation held subordinate securities issued by the credit card securitization trust with a notional principal amount of $7.3 billion and $7.7 billion . These securities serve as a form of credit enhancement to the senior debt securities and have a stated interest rate of zero percent . During the three months ended March 31, 2018 , there were $254 million of these subordinate securities issued. None were issued in the three months ended March 31, 2019 . Resecuritization Trusts The Corporation transfers securities, typically MBS, into resecuritization VIEs 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 $4.4 billion and $6.7 billion of securities during the three months ended March 31, 2019 and 2018 . Securities transferred into resecuritization VIEs were measured at fair value with changes in fair value recorded in trading account income prior to the resecuritization and, accordingly, no gain or loss on sale was recorded. Resecuritization proceeds included securities with an initial fair value of $1.3 billion during both the three months ended March 31, 2019 and 2018 . Substantially all of the other 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 $2.3 billion and $2.1 billion at March 31, 2019 and December 31, 2018 . The weighted-average remaining life of bonds held in the trusts at March 31, 2019 was 7.3 years . There were no material write-downs or downgrades of assets or issuers during the three months ended March 31, 2019 and 2018 . Other Variable Interest Entities The table below summarizes select information related to other VIEs in which the Corporation held a variable interest at March 31, 2019 and December 31, 2018 . Other VIEs Consolidated Unconsolidated Total Consolidated Unconsolidated Total (Dollars in millions) March 31, 2019 December 31, 2018 Maximum loss exposure $ 3,950 $ 24,383 $ 28,333 $ 4,177 $ 24,498 $ 28,675 On-balance sheet assets Trading account assets $ 2,134 $ 890 $ 3,024 $ 2,335 $ 860 $ 3,195 Debt securities carried at fair value — 82 82 — 84 84 Loans and leases 1,872 4,086 5,958 1,949 3,940 5,889 Allowance for loan and lease losses (2 ) (30 ) (32 ) (2 ) (30 ) (32 ) All other assets 50 18,993 19,043 53 18,885 18,938 Total $ 4,054 $ 24,021 $ 28,075 $ 4,335 $ 23,739 $ 28,074 On-balance sheet liabilities Long-term debt $ 98 $ — $ 98 $ 152 $ — $ 152 All other liabilities 7 3,982 3,989 7 4,231 4,238 Total $ 105 $ 3,982 $ 4,087 $ 159 $ 4,231 $ 4,390 Total assets of VIEs $ 4,054 $ 92,018 $ 96,072 $ 4,335 $ 94,746 $ 99,081 Customer VIEs Customer VIEs include credit-linked, equity-linked and commodity-linked note VIEs, repackaging VIEs and asset acquisition VIEs, 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 VIEs totaled $2.0 billion and $2.1 billion at March 31, 2019 and December 31, 2018 , 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 VIEs. Collateralized Debt Obligation VIEs The Corporation receives fees for structuring CDO VIEs, which hold diversified pools of fixed-income securities, typically corporate debt or ABS, which the CDO VIEs 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 $319 million and $421 million at March 31, 2019 and December 31, 2018 . Investment VIEs The Corporation sponsors, invests in or provides financing, which may be in connection with the sale of assets, to a variety of investment VIEs 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 March 31, 2019 and December 31, 2018 , the Corporation’s consolidated investment VIEs had total assets of $188 million and $270 million . The Corporation also held investments in unconsolidated VIEs with total assets of $34.9 billion and $37.7 billion at March 31, 2019 and December 31, 2018 . The Corporation’s maximum loss exposure associated with both consolidated and unconsolidated investment VIEs totaled $7.3 billion and $7.2 billion at March 31, 2019 and December 31, 2018 comprised primarily of on-balance sheet assets less non-recourse liabilities. Leveraged Lease Trusts The Corporation’s net investment in consolidated leveraged lease trusts totaled $1.8 billion at both March 31, 2019 and December 31, 2018 . 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 VIEs 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 VIE. 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 $16.8 billion and $17.0 billion at March 31, 2019 and December 31, 2018 . 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 $8.7 billion and $8.9 billion , including unfunded commitments to provide capital contributions of $3.7 billion and $3.8 billion at March 31, 2019 and December 31, 2018 . 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 $280 million and $248 million and reported pretax losses in other income of $248 million and $208 million for the three months ended March 31, 2019 and 2018 . 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

Leases [Abstract]
Leases	Leases The Corporation enters into both lessor and lessee arrangements. For more information on lease accounting, see Note 1 – Summary of Significant Accounting Principles and on lease financing receivables, see Note 5 – Outstanding Loans and Leases . Lessor Arrangements The Corporation’s lessor arrangements primarily consist of operating, sales-type and direct financing leases for equipment. Lease agreements may include options to renew and for the lessee to purchase the leased equipment at the end of the lease term. At March 31, 2019 , the total net investment in sales-type and direct financing leases was $22.6 billion , comprised of $20.3 billion in lease receivables and $2.3 billion in unguaranteed residuals. In certain cases, the Corporation obtains third-party residual value insurance to reduce its residual asset risk. The carrying value of residual assets with third-party residual value insurance for at least a portion of the asset value was $3.4 billion . For the three months ended March 31, 2019 , total lease income was $426 million , consisting of $205 million from sales-type and direct financing leases and $221 million from operating leases. Lessee Arrangements The Corporation’s lessee arrangements predominantly consist of operating leases for premises and equipment; the Corporation’s financing leases are not significant. Right-of-use assets were $9.6 billion and lease liabilities were $9.9 billion at March 31, 2019 . The weighted-average discount rate used to calculate the present value of future minimum lease payments was four percent . Lease terms may contain renewal and extension options and early termination features. Generally, these options do not impact the lease term because the Corporation is not reasonably certain that it will exercise the options. The weighted-average lease term was 7.8 years at March 31, 2019 . The table below provides the components of lease cost and supplemental information for the three months ended March 31, 2019 . Lease Cost and Supplemental Information (Dollars in millions) Three Months Ended March 31, 2019 Operating lease cost $ 519 Variable lease cost (1) 127 Total lease cost (2) $ 646 Right-of-use assets obtained in exchange for new operating lease liabilities (3) $ 385 Operating cash flows from operating leases (4) 501 (1) Primarily consists of payments for common area maintenance and property taxes.

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 2018 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 following table includes the notional amount of unfunded legally binding lending commitments net of amounts distributed (i.e., syndicated or participated) to other financial institutions. The distributed amounts were $10.4 billion and $10.7 billion at March 31, 2019 and December 31, 2018 . At March 31, 2019 , the carrying value of these commitments, excluding commitments accounted for under the fair value option, was $820 million , including deferred revenue of $18 million and a reserve for unfunded lending commitments of $802 million . At December 31, 2018 , the comparable amounts were $813 million , $16 million and $797 million , respectively. The carrying value of these commitments is classified in accrued expenses and other liabilities on the Consolidated Balance Sheet. 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. The table below also includes the notional amount of commitments of $3.1 billion at both March 31, 2019 and December 31, 2018 that are accounted for under the fair value option. However, the table excludes cumulative net fair value of $106 million and $169 million at March 31, 2019 and December 31, 2018 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 16 – Fair Value Option .

Amounts in the table include consumer SBLCs of $390 million and $372 million at March 31, 2019 and December 31, 2018 . (2) At March 31, 2019 and December 31, 2018 , included are letters of credit of $606 million and $422 million related to certain liquidity commitments of VIEs. For additional information, see Note 7 – Securitizations and Other Variable Interest Entities . (3) Includes business card unused lines of credit. Other Commitments At March 31, 2019 and December 31, 2018 , the Corporation had commitments to purchase loans (e.g., residential mortgage and commercial real estate) of $426 million and $329 million , which upon settlement will be included in loans or LHFS, and commitments to purchase commercial loans of $270 million and $463 million , which upon settlement will be included in trading account assets. At March 31, 2019 and December 31, 2018 , the Corporation had commitments to purchase commodities, primarily liquefied natural gas, of $1.1 billion and $1.3 billion , which upon settlement will be included in trading account assets. At March 31, 2019 and December 31, 2018 , the Corporation had commitments to enter into resale and forward-dated resale and securities borrowing agreements of $82.1 billion and $59.7 billion , and commitments to enter into forward-dated repurchase and securities lending agreements of $52.0 billion and $21.2 billion . These commitments expire primarily within the next 21 months . At March 31, 2019 and December 31, 2018 , the Corporation had a commitment to originate or purchase up to $3.1 billion and $3.0 billion on a rolling 12-month basis, of auto loans and leases from a strategic partner. This commitment extends through November 2022 and can be terminated with 12 months prior notice. 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 March 31, 2019 and December 31, 2018 , the notional amount of these guarantees totaled $9.1 billion and $9.8 billion . At March 31, 2019 and December 31, 2018 , the Corporation’s maximum exposure related to these guarantees totaled $1.4 billion and $1.5 billion , with estimated maturity dates between 2033 and 2039. 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. If the merchant processor fails to meet its obligation to reimburse the cardholder for disputed transactions, then the Corporation could be held liable. For the three months ended March 31, 2019 and 2018 , the sponsored entities processed and settled $205.6 billion and $200.7 billion of transactions and recorded losses of $4 million and $8 million . At March 31, 2019 and December 31, 2018 , the maximum potential exposure for sponsored transactions totaled $346.6 billion and $348.1 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. A significant portion of our merchant processing activity is performed by a joint venture formed in 2009. At that time, the Corporation contributed its merchant processing business, valued at $4.7 billion , in exchange for a minority ownership interest in the venture. The joint venture is accounted for as an equity method investment and reported in All Other . Since 2009, the carrying value of the investment has decreased to $2.8 billion at March 31, 2019 due to cash distributions received, the Corporation’s proportionate share of income and an impairment charge recorded in 2011. The term of the joint venture is governed by various operating agreements that automatically renew in accordance with their terms unless either partner gives a written notice of termination at least one year prior to the end of the term. The current term ends in June 2020. If either partner decides to terminate the joint venture, the fair value of the Corporation’s investment would no longer be based on the cash flows of the joint venture into perpetuity, but instead would be based primarily on the estimated fair value of finite-lived assets that would be received upon dissolution. That change would likely result in a material impairment of the investment. Representations and Warranties Obligations and Corporate Guarantees For more information on representations and warranties obligations and corporate guarantees, and the related reserve and estimated range of possible loss, see Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . The reserve for representations and warranties obligations and corporate guarantees at March 31, 2019 and December 31, 2018 was $1.9 billion and $2.0 billion and is included in accrued expenses and other liabilities on the Consolidated Balance Sheet and the related provision is included in other income in the Consolidated Statement of Income. The representations and warranties reserve represents the Corporation’s best estimate of probable incurred losses. It is reasonably possible that future representations and warranties losses may occur in excess of the amounts recorded for these exposures. See Litigation and Regulatory Matters below for the Corporation’s combined range of possible loss in excess of the reserve for representations and warranties and the accrued liability for litigation. 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 $6.1 billion and $5.9 billion at March 31, 2019 and December 31, 2018 . The estimated maturity dates of these obligations extend up to 2040 . The Corporation has made no material payments under these guarantees. For more information on maximum potential future payments under VIE-related liquidity commitments, see Note 7 – Securitizations and Other Variable Interest Entities . 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. Guarantees of Certain Long-term Debt The Corporation, as the parent company, fully and unconditionally guarantees the securities issued by BofA Finance LLC, a 100 percent owned finance subsidiary of the Corporation, and effectively provides for the full and unconditional guarantee of trust securities issued by certain statutory trust companies that are 100 percent owned finance subsidiaries of the Corporation. Litigation and Regulatory Matters The following disclosure supplements Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K , collectively the commitments and contingencies disclosures. 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 the eventual outcome of the pending matters, the timing of the ultimate resolution of these matters, or any eventual loss, fines or penalties related to each pending matter. 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. Excluding expenses of internal and external legal service providers, litigation-related expense of $73 million and $116 million was recognized for the three months ended March 31, 2019 and 2018 . For a limited number of the matters disclosed in the commitments and contingencies disclosures 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. With respect to such matters, 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 disclosed matters where an estimate of the range of possible loss is possible, as well as for representations and warranties exposures, management currently estimates the aggregate range of reasonably possible loss for these exposures is $0 to $1.9 billion in excess of the accrued liability, if any. 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 in the commitments and contingencies disclosures regarding the nature of the litigation 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 in the commitments and contingencies disclosures, 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.

On February 7, 2019, following approval by the Federal Reserve, the Board authorized the repurchase of an additional $2.5 billion of common stock through June 30, 2019. This common stock repurchase authorization includes only common stock. During the three months ended March 31, 2019 , the Corporation repurchased and retired 220 million shares of common stock in connection with the 2018 Comprehensive Capital Analysis and Review (CCAR) capital plan. These repurchases reduced shareholders’ equity by $6.3 billion . During the three months ended March 31, 2019 , in connection with employee stock plans, the Corporation issued 83 million shares of its common stock and, to satisfy tax withholding obligations, repurchased 32 million shares of its common stock. At March 31, 2019 , the Corporation had reserved 443 million unissued shares of common stock for future issuances under employee stock plans, convertible notes and preferred stock. Preferred Stock During the three months ended March 31, 2019 , the Corporation declared $442 million of cash dividends on preferred stock. There were no issuances or redemptions of preferred stock during the three months ended March 31, 2019 . Restricted Stock Units During the three months ended March 31, 2019 , the Corporation granted 94 million restricted stock unit (RSU) awards to certain employees under the Bank of America Corporation Key Employee Equity Plan. These awards were authorized to settle predominantly in shares of common stock of the Corporation and will be expensed based on the grant-date fair value of the shares. Certain RSUs will be settled in cash or contain settlement provisions that subject these awards to variable accounting whereby compensation expense is adjusted to fair value based on changes in the share price of the Corporation’s common stock up to the settlement date. Of the RSUs granted, 71 million will vest predominantly over three years with most vesting in one-third increments on each of the first three anniversaries of the grant date provided that the employee remains continuously employed with the Corporation during that time, and will be expensed ratably over the vesting period, net of estimated forfeitures, for non-retirement eligible employees. For RSUs granted to employees who are retirement eligible, the awards are deemed authorized as of the beginning of the year preceding the grant date when the incentive award plans are generally approved. As a result, the estimated value is expensed ratably over the year preceding the grant date. Additionally, 23 million of the RSUs granted will vest predominantly over four years with most vesting in one-fourth increments on each of the first four anniversaries of the grant date provided that the employee remains continuously employed with the Corporation during that time, and will be expensed ratably over the vesting period, net of estimated forfeitures.

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 months ended March 31, 2019 and 2018 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 2018 Annual Report on Form 10-K . Three Months Ended March 31 (In millions, except per share information) 2019 2018 Earnings per common share Net income $ 7,311 $ 6,918 Preferred stock dividends (442 ) (428 ) Net income applicable to common shareholders $ 6,869 $ 6,490 Average common shares issued and outstanding 9,725.9 10,322.4 Earnings per common share $ 0.71 $ 0.63 Diluted earnings per common share Net income applicable to common shareholders $ 6,869 $ 6,490 Average common shares issued and outstanding 9,725.9 10,322.4 Dilutive potential common shares (1) 61.4 150.3 Total diluted average common shares issued and outstanding 9,787.3 10,472.7 Diluted earnings per common share $ 0.70 $ 0.62 (1) Includes incremental dilutive shares from RSUs, restricted stock and warrants. For both the three months ended March 31, 2019 and 2018 , 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 months ended March 31, 2018 , average options to purchase seven 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. For the three months ended March 31, 2018 , average warrants to purchase 122 million shares of common stock were included in the computation of EPS under the treasury stock method. These warrants expired on October 29, 2018. For the three months ended March 31, 2019 and 2018 , average warrants to purchase 14 million and 142 million

Fair Value Measurements

Fair Value Measurements	3 Months Ended

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 made if the significant inputs used in the financial models measuring the fair values of the assets and liabilities become unobservable or observable in the current marketplace. During the three months ended March 31, 2019 , 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, how the Corporation measures fair value and valuation techniques, see Note 1 – Summary of Significant Accounting Principles and Note 20 – Fair Value Measurements to the Consolidated Financial Statements of the Corporation’s 2018 Annual Report on Form 10-K . The Corporation accounts for certain financial instruments under the fair value option. For additional information, see Note 16 – Fair Value Option . Recurring Fair Value Assets and liabilities carried at fair value on a recurring basis at March 31, 2019 and December 31, 2018 , including financial instruments that the Corporation accounts for under the fair value option, are summarized in the following tables.

Transfers into Level 3 occur primarily due to decreased price observability, and transfers out of Level 3 occur primarily due to increased price observability. 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.

Sensitivity of Fair Value Measurements for Mortgage Servicing Rights The weighted-average lives and fair value of MSRs are sensitive to changes in modeled assumptions. The weighted-average life is a product of changes in market rates of interest, prepayment rates and other model and cash flow assumptions. The weighted-average life represents the average period of time that the MSRs’ cash flows are expected to be received. Absent other changes, an increase (decrease) to the weighted-average life would generally result in an increase (decrease) in the fair value of the MSRs. For example, as of March 31, 2019 , a 10 percent or 20 percent decrease in prepayment rates, which impacts the weighted-average life, could result in an increase in fair value of $64 million or $134 million , while a 10 percent or 20 percent increase in prepayment rates could result in a decrease in fair value of $59 million or $114 million . A 100 bp or 200 bp decrease in option-adjusted spread (OAS) levels could result in an increase in fair value of $55 million or $114 million , while a 100 bp or 200 bp increase in OAS levels could result in a decrease in fair value of $52 million or $100 million . These sensitivities are hypothetical and actual amounts may vary materially. For additional information on variations in assumptions and sensitivities on MSRs, see Note 20 – Fair Value Measurements to the Consolidated Financial Statements The Corporation holds certain assets that are measured at fair value, but only in certain situations (e.g., impairment) and these measurements are referred to herein as nonrecurring. The amounts below represent assets still held as of the reporting date for which a nonrecurring fair value adjustment was recorded during the three months ended March 31, 2019 and 2018 .

Summary of Significant Accoun_2

Summary of Significant Accounting Principles (Policies)	3 Months Ended
	Mar. 31, 2019
Accounting Policies [Abstract]
Principles of 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 Presentation	The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts and disclosures. Realized results could materially 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 2018 Annual Report on Form 10-K.
Accounting Standards	New Accounting Standards Lease Accounting On January 1, 2019, the Corporation adopted the new accounting standards that require lessees to recognize operating leases on the Consolidated Balance Sheet as right-of-use assets and lease liabilities based on the value of the discounted future lease payments. Lessor accounting is largely unchanged. Expanded disclosures about the nature and terms of lease agreements are required prospectively and are included in Note 9 – Leases . The Corporation elected to retain prior determinations of whether an existing contract contains a lease and how the lease should be classified. The Corporation elected to recognize leases existing on January 1, 2019 through a cumulative-effect adjustment which increased retained earnings by $165 million , with no adjustment to prior periods presented. Upon adoption, the Corporation also recognized right-of-use assets and lease liabilities of $9.7 billion . Adoption of the standard did not have a significant effect on the Corporation’s regulatory capital measures.
Lessor Arrangements	The Corporation provides equipment financing to its customers through a variety of lessor arrangements. Direct financing leases and sales-type leases are carried at the aggregate of lease payments receivable plus the estimated residual value of the leased property less unearned income, which is accreted to interest income over the lease terms using methods that approximate the interest method. Operating lease income is recognized on a straight-line basis. Leases generally do not contain non-lease components.
Lessee Arrangements	Substantially all of the Corporation’s lessee arrangements are operating leases. Under these arrangements, the Corporation records right-of-use assets and lease liabilities at lease commencement. Right-of-use assets are reported in other assets on the Consolidated Balance Sheet, and the related lease liabilities are reported in accrued expenses and other liabilities. All leases are recorded on the Consolidated Balance Sheet except for leases with an initial term less than 12 months for which the Corporation made the short-term lease election. Lease expense is recognized on a straight-line basis over the lease term and is recorded in occupancy and equipment expense in the Consolidated Statement of Income.

Fair Value, Assets Measured on Recurring Basis, Unobservable Input Reconciliation	The following tables present a reconciliation of all assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the three months ended March 31, 2019 and 2018 , including net realized and unrealized gains (losses) included in earnings and accumulated OCI. Transfers into Level 3 occur primarily due to decreased price observability, and transfers out of Level 3 occur primarily due to increased price observability. 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.
