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. Actual 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, and related notes thereto, of the Corporation’s 2020 Annual Report on Form 10-K.

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 and Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2020 Annual Report on Form 10-K . The following tables present derivative instruments included on the Consolidated Balance Sheet in derivative assets and liabilities at March 31, 2021 and December 31, 2020. Balances are presented on a gross basis, prior to the application of counterparty and cash collateral netting. Total derivative assets and liabilities are adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements and have been reduced by cash collateral received or paid.

(2) The net derivative asset and notional amount of written credit derivatives for which the Corporation held purchased credit derivatives with identical underlying referenced names were $2.2 billion and $269.8 billion at December 31, 2020. 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 more information, see Note 3 – Derivatives to the Consolidated Financial Statements of the Corporation’s 2020 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, 2021 and December 31, 2020 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. For more information on offsetting of securities financing agreements, see Note 9 – Federal Funds Sold or Purchased, Securities Financing Agreements, Short-term Borrowings and Restricted Cash . Offsetting of Derivatives (1) Derivative Derivative Liabilities Derivative Derivative Liabilities (Dollars in billions) March 31, 2021 December 31, 2020 Interest rate contracts Over-the-counter $ 196.7 $ 190.4 $ 247.7 $ 243.5 Exchange-traded 0.1 0.1 — — Over-the-counter cleared 9.1 9.8 10.2 9.1 Foreign exchange contracts Over-the-counter 80.7 81.7 92.2 96.5 Over-the-counter cleared 1.2 1.2 1.4 1.3 Equity contracts Over-the-counter 33.1 29.4 31.3 28.3 Exchange-traded 33.2 32.2 32.3 31.0 Commodity contracts Over-the-counter 3.9 4.9 3.5 5.0 Exchange-traded 0.8 1.0 0.7 0.7 Over-the-counter cleared 0.1 0.1 — — Credit derivatives Over-the-counter 6.4 6.0 5.2 5.6 Over-the-counter cleared 2.8 2.7 2.2 1.9 Total gross derivative assets/liabilities, before netting Over-the-counter 320.8 312.4 379.9 378.9 Exchange-traded 34.1 33.3 33.0 31.7 Over-the-counter cleared 13.2 13.8 13.8 12.3 Less: Legally enforceable master netting agreements and cash collateral received/paid Over-the-counter (285.9) (284.6) (345.7) (347.2) Exchange-traded (32.1) (32.1) (29.5) (29.5) Over-the-counter cleared (11.8) (11.8) (12.2) (11.8) Derivative assets/liabilities, after netting 38.3 31.0 39.3 34.4 Other gross derivative assets/liabilities (2) 7.6 11.3 7.9 11.1 Total derivative assets/liabilities 45.9 42.3 47.2 45.5 Less: Financial instruments collateral (3) (17.0) (14.5) (16.1) (16.6) Total net derivative assets/liabilities $ 28.9 $ 27.8 $ 31.1 $ 28.9 (1) Over-the-counter derivatives include bilateral transactions between the Corporation and a particular counterparty. Over-the-counter 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. 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, 2021 and 2020. Gains and Losses on Derivatives Designated as Fair Value Hedges Three Months Ended March 31 2021 2020 (Dollars in millions) Derivative Hedged Item Derivative Hedged Item Interest rate risk on long-term debt (1) $ (8,063) $ 8,002 $ 10,334 $ (10,276) Interest rate and foreign currency risk on long-term debt (2) (28) 26 505 (491) Interest rate risk on available-for-sale securities (3) 5,241 (5,150) (350) 342 Total $ (2,850) $ 2,878 $ 10,489 $ (10,425) (1) Amounts are recorded in interest expense in the Consolidated Statement of Income. (2) For the three months ended March 31, 2021 and 2020, the derivative amount includes gains (losses) of $(34) million and $734 million in interest expense, $8 million and $(241) million in market making and similar activities, and $(2) million and $12 million in accumulated other comprehensive income (OCI), respectively. Line item totals are in the Consolidated Statement of Income and on the Consolidated Balance Sheet. (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 and Liabilities March 31, 2021 December 31, 2020 (Dollars in millions) Carrying Value Cumulative Fair Value Adjustments (1) Carrying Value Cumulative Fair Value Adjustments (1) Long-term debt (2) $ 143,897 $ 2,304 $ 150,556 $ 8,910 Available-for-sale debt securities (2, 3, 4) 152,388 (4,881) 116,252 114 Trading account assets (5) 660 — 427 15 (1) Increase (decrease) to carrying value. (2) At March 31, 2021 and December 31, 2020, the cumulative fair value adjustments remaining on long-term debt and available-for-sale debt securities from discontinued hedging relationships resulted in an increase in the related liability of $2.1 billion and $3.7 billion and a decrease in the related asset of $71 million and $69 million, which are being amortized over the remaining contractual life of the de-designated hedged items. (3) These amounts include the amortized cost of the prepayable financial assets used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship (i.e. last-of-layer hedging relationship). At March 31, 2021 and December 31, 2020, the amortized cost of the closed portfolios used in these hedging relationships was $30.5 billion and $34.6 billion, of which $7.0 billion was designated in the last-of-layer hedging relationship at both dates. At March 31, 2021, the cumulative adjustment associated with these hedging relationships was a decrease of $115 million. At December 31, 2020, the cumulative adjustment was insignificant. (4) Carrying value represents amortized cost. (5) Represents hedging activities related to precious metals inventory. Cash Flow and Net Investment Hedges The table below summarizes certain information related to cash flow hedges and net investment hedges for the three months ended March 31, 2021 and 2020. Of the $688 million after-tax net loss ($917 million pretax) on derivatives in accumulated OCI at March 31, 2021, gains of $220 million after-tax ($294 million pretax) related to both open and terminated cash flow hedges are expected to be reclassified into earnings in the next 12 months. These net gains reclassified into earnings are expected to primarily increase 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 3 years, with a maximum length of time for certain forecasted transactions of 15 years. Gains and Losses on Derivatives Designated as Cash Flow and Net Investment Hedges Three Months Ended March 31 2021 2020 (Dollars in millions, amounts pretax) Gains (Losses) Recognized in Gains (Losses) Gains (Losses) Recognized in Gains (Losses) Cash flow hedges Interest rate risk on variable-rate assets (1) $ (1,057) $ 37 $ 591 $ (26) Price risk on forecasted MBS purchases (1) (393) 9 — — Price risk on certain compensation plans (2) 24 12 (82) — Total $ (1,426) $ 58 $ 509 $ (26) Net investment hedges Foreign exchange risk (3) $ 727 $ — $ 1,368 $ — (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, 2021 and 2020, amounts excluded from effectiveness testing and recognized in market making and similar activities were gains (losses) of $(2) million and $30 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 table below presents gains (losses) on these derivatives for the three months ended March 31, 2021 and 2020. 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) 2021 2020 Interest rate risk on mortgage activities (1, 2) $ (190) $ 379 Credit risk on loans (2) (17) 88 Interest rate and foreign currency risk on asset and liability management activities (3) 1,261 1,528 Price risk on certain compensation plans (4) 280 (757) (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 $19 million and $48 million for the three months ended March 31, 2021 and 2020. (2) Gains (losses) on these derivatives are recorded in other income. (3) Gains (losses) on these derivatives are recorded in market making and similar activities. (4) Gains (losses) on these derivatives are recorded in compensation and benefits 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. At March 31, 2021 and December 31, 2020, the Corporation had transferred $5.1 billion and $5.2 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 $5.1 billion and $5.2 billion at the transfer dates. At March 31, 2021 and December 31, 2020, the fair value of the transferred securities was $5.4 billion and $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 2020 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, 2021 and 2020. This table includes debit valuation adjustment (DVA) and funding valuation adjustment (FVA) gains (losses). Global Markets results in Note 17 – 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 $548 million and $557 million for the three months ended March 31, 2021 and 2020. (2) Includes commodity risk. 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 2020 Annual Report on Form 10-K. Credit derivative instruments where the Corporation is the seller of credit protection and their expiration at March 31, 2021 and December 31, 2020 are summarized in the table below.

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 (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 Certain 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, 2021 and December 31, 2020, the Corporation held cash and securities collateral of $89.3 billion and $96.5 billion and posted cash and securities collateral of $72.7 billion and $88.6 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 over-the-counter 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 2020 Annual Report on Form 10-K. At March 31, 2021, 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 $3.0 billion, including $1.9 billion for Bank of America, National Association.

(2) Residential mortgage loans accruing past due 90 days or more are fully-insured loans. At March 31, 2021 and December 31, 2020 residential mortgage includes $527 million and $537 million of loans on which interest had been curtailed by the Federal Housing Administration (FHA), and therefore were no longer accruing interest, although principal was still insured, and $201 million and $225 million of loans on which interest was still accruing. (3) Primarily relates to loans for which the estimated fair value of the underlying collateral less any costs to sell is greater than the amortized cost of the loans as of the reporting date. 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. For more information on the portfolio segments, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation’s 2020 Annual Report on Form 10-K. Within the Consumer Real Estate portfolio segment, the primary credit quality indicators are refreshed loan-to-value (LTV) and refreshed Fair Isaac Corporation (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. Home equity loans are evaluated using combined loan-to-value (CLTV), which measures the carrying value of the Corporation’s loan and available line of credit combined with any outstanding senior liens against the property 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. Certain borrowers (e.g., borrowers that have had debts discharged in a bankruptcy proceeding) may not have their FICO scores updated. FICO scores are also a primary credit quality indicator for the Credit Card and Other Consumer portfolio segment and the business card portfolio within U.S. small business commercial. Within the Commercial portfolio segment, loans are evaluated using the internal classifications of pass rated or reservable criticized as the primary credit quality indicators. The term reservable criticized refers to those commercial loans that are internally classified or listed by the Corporation as Special Mention, Substandard or Doubtful, which are asset quality categories defined by regulatory authorities. These assets have an elevated level of risk and may have a high probability of default or total loss. Pass rated refers to all loans not considered reservable criticized. In addition to these primary credit quality indicators, the Corporation uses other credit quality indicators for certain types of loans. 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 and year of origination for term loan balances at March 31, 2021, including revolving loans that converted to term loans without an additional credit decision after origination or through a TDR.

Troubled Debt Restructurings The Corporation has been entering into loan modifications with borrowers in response to the pandemic, most of which are not classified as TDRs, and therefore are not included in the following discussion. For more information on the criteria for classifying loans as TDRs, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation’s 2020 Annual Report on Form 10-K. Consumer Real Estate Modifications of consumer real estate loans are classified as TDRs when the borrower is experiencing financial difficulties and a concession has been granted. Concessions may include reductions in interest rates, capitalization of past due amounts, principal and/or interest forbearance, payment extensions, principal and/or interest forgiveness, or combinations thereof. Prior to permanently modifying a loan, the Corporation may enter into trial modifications with certain borrowers under both government and proprietary programs. Trial modifications generally represent a three- to four-month period during which the borrower makes monthly payments under the anticipated modified payment terms. Upon successful completion of the trial period, the Corporation and the borrower enter into a permanent modification. Binding trial modifications are classified as TDRs when the trial offer is made and continue to be classified as TDRs regardless of whether the borrower enters into a permanent modification. Consumer real estate loans of $358 million that have been discharged in Chapter 7 bankruptcy with no change in repayment terms and not reaffirmed by the borrower were included in TDRs at March 31, 2021, of which $103 million were classified as nonperforming and $65 million were loans fully insured. Consumer real estate TDRs are measured primarily based on the net present value of the estimated cash flows discounted at the loan’s original effective interest rate. If the carrying value of a TDR exceeds this amount, a specific allowance is recorded as a component of the allowance for loan and lease losses. Alternatively, consumer real estate TDRs that are considered to be dependent solely on the collateral for repayment (e.g., due to the lack of income verification) are measured based on the estimated fair value of the collateral, and a charge-off is recorded if the carrying value exceeds the fair value of the collateral. Consumer real estate loans that reach 180 days past due prior to modification are charged off to their net realizable value, less costs to sell, before they are modified as TDRs in accordance with established policy. Subsequent declines in the fair value of the collateral after a loan has reached 180 days past due are recorded as charge-offs. Fully-insured loans are protected against principal loss, and therefore, the Corporation does not record an allowance for loan and lease losses on the outstanding principal balance, even after they have been modified in a TDR. At March 31, 2021 and December 31, 2020, 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 $101 million and $123 million at March 31, 2021 and December 31, 2020. The carrying value of consumer real estate loans, including fully-insured loans, for which formal foreclosure proceedings were in process at March 31, 2021 was $1.1 billion. Although the Corporation has paused formal loan foreclosure proceedings and foreclosure sales for occupied properties, during the three months ended March 31, 2021, the Corporation reclassified $10 million of consumer real estate loans completed or which were in process prior to the pause in foreclosures, 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 table below presents the March 31, 2021 and 2020 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, 2021 and 2020. 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.

(2) Includes loans discharged in Chapter 7 bankruptcy with no change in repayment terms that are classified as TDRs. (3) Includes trial modification offers to which the customer did not respond. Credit Card and Other Consumer 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.

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 and liabilities of consolidated and unconsolidated VIEs at March 31, 2021 and December 31, 2020 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 March 31, 2021 and December 31, 2020 resulting from its involvement with consolidated and unconsolidated VIEs in which the Corporation holds a variable interest. 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 6 – Securitizations and Other Variable Interest Entities to the Consolidated Financial Statements of the Corporation’s 2020 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 and Allowance for Credit Losses. In addition, the Corporation has used VIEs in connection with its funding activities. The Corporation did not provide financial support to consolidated or unconsolidated VIEs during the three months ended March 31, 2021 or the year ended December 31, 2020 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 $942 million and $929 million at March 31, 2021 and December 31, 2020. 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 10 – 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, 2021 and 2020. First-lien Mortgage Securitizations Residential Mortgage - Agency Commercial Mortgage Three Months Ended March 31 (Dollars in millions) 2021 2020 2021 2020 Proceeds from loan sales (1) $ 1,243 $ 1,552 $ 665 $ 2,072 Gains on securitizations (2) 2 6 33 41 Repurchases from securitization trusts (3) 80 128 — — (1) The Corporation transfers residential mortgage loans to securitizations sponsored primarily by the Government-sponsored enterprise (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 typically 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 $33 million and $27 million net of hedges, during the three months ended March 31, 2021 and 2020, respectively, 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 $149.7 billion and $182.9 billion at March 31, 2021 and 2020. Servicing fee and ancillary fee income on serviced loans was $113 million and $128 million during the three months ended March 31, 2021 and 2020. Servicing advances on serviced loans, including loans serviced for others and loans held for investment, were $2.2 billion at both March 31, 2021 and December 31, 2020. For more information on MSRs, see Note 14 – Fair Value Measurements .

For more information, see Note 10 – Commitments and Contingencies and Note 14 – Fair Value Measurements . (2) Principal balance outstanding includes loans where the Corporation was the transferor to securitization VIEs with which it has continuing involvement, which may include servicing the loans. Other Asset-backed Securitizations The following table summarizes select information related to home equity, credit card and other asset-backed VIEs in which the Corporation held a variable interest at March 31, 2021 and December 31, 2020.

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 more information, see Note 10 – Commitments and Contingencies . (2) At March 31, 2021 and December 31, 2020, loans and leases in the consolidated credit card trust included $5.0 billion and $7.6 billion of seller’s interest. (3) The retained senior securities were valued using quoted market prices or observable market inputs (Level 2 of the fair value hierarchy). 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. No new senior debt securities were issued to third-party investors from the credit card securitization trust during the three months ended March 31, 2021 and 2020. At March 31, 2021 and December 31, 2020, the Corporation held subordinate securities issued by the credit card securitization trust with a notional principal amount of $6.6 billion and $6.8 billion. These securities serve as a form of credit enhancement to the senior debt securities and have a stated interest rate of zero percent. No subordinate securities were issued by the credit card securitization trust during the three months ended March 31, 2021 and 2020. Resecuritization Trusts The Corporation transfers securities, typically MBS, into resecuritization VIEs generally 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 $1.0 billion and $7.4 billion of securities during the three months ended March 31, 2021 and 2020. Securities transferred into resecuritization VIEs were measured at fair value with changes in fair value recorded in market making and similar activities prior to the resecuritization and, accordingly, no gain or loss on sale was recorded. During the three months ended March 31, 2021 and 2020, resecuritization proceeds included securities with an initial fair value of $178 million and $526 million. Substantially all of the trading account securities carried at fair value 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 $3.6 billion and $3.5 billion at March 31, 2021 and December 31, 2020. The weighted-average remaining life of bonds held in the trusts at March 31, 2021 was 6.5 years. There were no significant write-downs or downgrades of assets or issuers during the three months ended March 31, 2021 and 2020. 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, 2021 and December 31, 2020. Other VIEs Consolidated Unconsolidated Total Consolidated Unconsolidated Total (Dollars in millions) March 31, 2021 December 31, 2020 Maximum loss exposure $ 4,483 $ 24,276 $ 28,759 $ 4,106 $ 23,870 $ 27,976 On-balance sheet assets Trading account assets $ 2,265 $ 611 $ 2,876 $ 2,080 $ 623 $ 2,703 Debt securities carried at fair value — 9 9 — 9 9 Loans and leases 2,347 225 2,572 2,108 184 2,292 Allowance for loan and lease losses (3) (10) (13) (3) (3) (6) All other assets 47 22,948 22,995 54 22,553 22,607 Total $ 4,656 $ 23,783 $ 28,439 $ 4,239 $ 23,366 $ 27,605 On-balance sheet liabilities Short-term borrowings $ 37 $ — $ 37 $ 22 $ — $ 22 Long-term debt 136 — 136 111 — 111 All other liabilities — 5,616 5,616 — 5,658 5,658 Total $ 173 $ 5,616 $ 5,789 $ 133 $ 5,658 $ 5,791 Total assets of VIEs $ 4,656 $ 80,929 $ 85,585 $ 4,239 $ 77,984 $ 82,223 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 $2.5 billion and $2.3 billion at March 31, 2021 and December 31, 2020, 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 $288 million and $298 million at March 31, 2021 and December 31, 2020. 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, 2021 and December 31, 2020, the Corporation’s consolidated investment VIEs had total assets of $780 million and $494 million. The Corporation also held investments in unconsolidated VIEs with total assets of $5.9 billion and $5.4 billion at March 31, 2021 and December 31, 2020. The Corporation’s maximum loss exposure associated with both consolidated and unconsolidated investment VIEs totaled $1.9 billion and $1.5 billion at March 31, 2021 and December 31, 2020 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 $1.6 billion and $1.7 billion at March 31, 2021 and December 31, 2020. 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 $22.4 billion and $22.0 billion at March 31, 2021 and December 31, 2020. 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 $11.2 billion, including unfunded commitments to provide capital contributions of $5.0 billion, at both March 31, 2021 and December 31, 2020. The unfunded commitments are expected to be paid over the next five years. During the three months ended March 31, 2021 and 2020, the Corporation recognized tax credits and other tax benefits from investments in affordable housing partnerships of $393 million and $268 million and reported pretax losses in other income of $276 million and $272 million. These tax credits are recognized as part of the Corporation’s annual effective tax rate used to determine tax expense in a given quarter. The Corporation may 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.

Commitments and Contingencies

Commitments and Contingencies	3 Months Ended

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 2020 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 $10.9 billion and $10.5 billion at March 31, 2021 and December 31, 2020. The carrying value of these commitments at March 31, 2021 and December 31, 2020, excluding commitments accounted for under the fair value option, was $1.8 billion and $1.9 billion, which primarily related to the reserve for unfunded lending commitments. 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 following table includes the notional amount of commitments of $4.6 billion and $4.0 billion at March 31, 2021 and December 31, 2020 that are accounted for under the fair value option. However, the table excludes cumulative net fair value of $91 million and $99 million at March 31, 2021 and December 31, 2020 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.

(2) 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 $25.2 billion and $9.6 billion at March 31, 2021, and $25.0 billion and $10.2 billion at December 31, 2020. Amounts in the table include consumer SBLCs of $481 million and $500 million at March 31, 2021 and December 31, 2020. (3) At both March 31, 2021 and December 31, 2020, included are letters of credit of $1.8 billion related to certain liquidity commitments of VIEs. For more information, see Note 6 – Securitizations and Other Variable Interest Entities . (4) Includes business card unused lines of credit. Other Commitments At March 31, 2021 and December 31, 2020, the Corporation had commitments to purchase loans (e.g., residential mortgage and commercial real estate) of $138 million and $93 million, which upon settlement will be included in trading account assets, loans or LHFS, and commitments to purchase commercial loans of $726 million and $645 million, which upon settlement will be included in trading account assets. At March 31, 2021 and December 31, 2020, the Corporation had commitments to purchase commodities, primarily liquefied natural gas, of $430 million and $582 million, which upon settlement will be included in trading account assets. At March 31, 2021 and December 31, 2020, the Corporation had commitments to enter into resale and forward-dated resale and securities borrowing agreements of $119.0 billion and $66.5 billion, and commitments to enter into forward-dated repurchase and securities lending agreements of $60.6 billion and $32.1 billion. These commitments generally expire within the next 12 months. At both March 31, 2021 and December 31, 2020, the Corporation had a commitment to originate or purchase up to $3.9 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 both March 31, 2021 and December 31, 2020, the notional amount of these guarantees totaled $7.1 billion. At both March 31, 2021 and December 31, 2020, the Corporation’s maximum exposure related to these guarantees totaled $1.1 billion, with estimated maturity dates between 2033 and 2039. Merchant Services The Corporation in its role as merchant acquirer or as a sponsor of other merchant acquirers may be held liable for any reversed charges that cannot be collected from the merchants, due to, among other things, merchant fraud or insolvency. If charges are properly reversed after a purchase and cannot be collected from either the merchants or merchant acquirers, the Corporation may be held liable for these reversed charges. The ability to reverse a charge is primarily governed by the applicable regulatory and card network rules, which include, but are not limited to, the type of charge, type of payment used and time limits. For the three months ended March 31, 2021, the Corporation processed an aggregate purchase volume of $301.1 billion. The Corporation’s risk in this area primarily relates to circumstances where a cardholder has purchased goods or services for future delivery. The Corporation mitigates this risk by requiring cash deposits, guarantees, letters of credit or other types of collateral from certain merchants. The Corporation’s reserves for contingent losses and the losses incurred related to the merchant processing activity were not significant. The Corporation continues to monitor its exposure in this area due to the potential economic impacts of the pandemic. Representations and Warranties Obligations and Corporate Guarantees For more information on representations and warranties obligations and corporate guarantees, see Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation’s 2020 Annual Report on Form 10-K . The reserve for representations and warranties obligations and corporate guarantees was $1.3 billion at both March 31, 2021 and December 31, 2020 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, is based on its experience in previous negotiations, and is subject to judgment, a variety of assumptions, and known or unknown uncertainties. Future representations and warranties losses may occur in excess of the amounts recorded for these exposures; however, the Corporation does not expect such amounts to be material to the Corporation's financial condition and liquidity. 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. Fixed Income Clearing Corporation Sponsored Member Repo Program The Corporation acts as a sponsoring member in a repo program whereby the Corporation clears certain eligible resale and repurchase agreements through the Government Securities Division of the Fixed Income Clearing Corporation on behalf of clients that are sponsored members in accordance with the Fixed Income Clearing Corporation’s rules. As part of this program, the Corporation guarantees the payment and performance of its sponsored members to the Fixed Income Clearing Corporation. The Corporation’s guarantee obligation is secured by a security interest in cash or high-quality securities collateral placed by clients with the clearinghouse and therefore, the potential for the Corporation to incur significant losses under this arrangement is remote. The Corporation’s maximum potential exposure, without taking into consideration the related collateral, was $3.4 billion and $22.5 billion at March 31, 2021 and December 31, 2020. 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 payments under these agreements are approximately $9.2 billion and $8.8 billion at March 31, 2021 and December 31, 2020. The estimated maturity dates of these obligations extend up to 2049. 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 6 – 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 consolidated 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 disclosures supplement the disclosure in Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation’s 2020 Annual Report on Form 10-K (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 the eventual outcome of the pending matters, timing of the ultimate resolution of these matters, or eventual loss, fines or penalties related to each pending matter. As a matter develops, the Corporation, in conjunction with any outside counsel handling the matter, evaluates whether such matter presents a loss contingency that is probable and estimable, and, for the matter described below and the matters disclosed in the prior commitments and contingencies disclosure, whether a loss in excess of any accrued liability is reasonably possible in future periods. 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 $34 million and $24 million was recognized for the three months ended March 31, 2021 and 2020. For any matter disclosed in this Note and in the prior commitments and contingencies disclosure, for which a loss in future periods is reasonably possible and estimable (whether in excess of an accrued liability or where there is no accrued liability) and for representations and warranties exposures, the Corporation’s estimated range of possible loss is $0 to $1.3 billion in excess of the accrued liability, if any, as of March 31, 2021. The accrued liability and estimated range of possible loss are based upon currently available information and subject to significant judgment, a variety of assumptions and known and unknown uncertainties. The matters underlying the accrued liability and estimated range of possible loss are unpredictable and may change from time to time, and actual losses may vary significantly from the current estimate and accrual. The estimated range of possible loss 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 the litigation and, where specified, associated claimed damages. Based on current knowledge, and taking into account accrued liabilities, management does not believe that loss contingencies arising from pending matters, including the matter described below, and in the prior commitments and contingencies disclosure, will have a material adverse effect on the consolidated financial condition or liquidity of the Corporation. However, in light of the significant judgment, variety of assumptions and uncertainties involved in those matters, some of which are beyond the Corporation’s control, and the very large or indeterminate damages sought in some of those matters, an adverse outcome in one or more of these matters could be material to the Corporation’s business or results of operations for any particular reporting period, or cause significant reputational harm. LIBOR, Other Reference Rates, Foreign Exchange and Bond Trading Matters On April 28, 2021, the European Commission concluded its investigation regarding trading by various financial institutions in sovereign, supranational, and agency bonds by issuing a fine in an amount not material to the Corporation.

During the three months ended March 31, 2021, the Corporation repurchased and retired 101 million shares of common stock, which reduced shareholders’ equity by $3.5 billion. During the three months ended March 31, 2021, in connection with employee stock plans, the Corporation issued 63 million shares of its common stock and, to satisfy tax withholding obligations, repurchased 24 million shares of its common stock. At March 31, 2021, the Corporation had reserved 451 million unissued shares of common stock for future issuances under employee stock plans, convertible notes and preferred stock. On April 22, 2021, the Board of Directors declared a quarterly common stock dividend at the current rate of $0.18 per share. Preferred Stock During the three months ended March 31, 2021, the Corporation declared $490 million of cash dividends on preferred stock. On January 28, 2021, the Corporation issued approximately 37,000 shares of 4.125% Non-Cumulative Preferred Stock, Series PP for $915 million, with quarterly dividends commencing in May 2021. The Series PP preferred stock has a liquidation preference of 25,000 per share and is subject to certain restrictions in the event the Corporation fails to declare and pay full dividends. During the three months ended March 31, 2021, the Corporation fully redeemed Series CC and Series T preferred stock for a total of $1.1 billion. Additionally, on April 25, 2021, the Corporation fully redeemed Series EE preferred stock for $900 million. For more information on the Corporation's preferred stock, including liquidation preference, dividend requirements and redemption period, see Note 13 – Shareholders’ Equity to the Consolidated Financial Statements of the Corporation’s 2020 Annual Report on Form 10-K. Restricted Stock Units During the three months ended March 31, 2021, the Corporation granted 98 million restricted stock unit (RSU) awards to certain employees under the Bank of America Key Employee Equity Plan. Other than an insignificant amount that are settled in cash, the RSUs will be settled in shares of common stock of the Corporation. Eighteen million of the RSU awards will vest over three years, and the remainder will generally vest over four years, provided that the employee remains continuously employed with the Corporation during that time. The RSUs will be expensed ratably over the life of the awards, net of estimated forfeitures, based on the grant-date fair value of the shares, except for awards that contain a retirement-eligibility provision and were issued to retirement-eligible employees, as these awards are generally expensed in the year preceding the grant date. Certain RSU awards granted during the three months ended March 31, 2021 were subsequently modified to include a retirement-eligibility provision, resulting in additional compensation and benefits expense of $269 million during the three months ended March 31, 2021. For more information, see Note 18 – Stock-based Compensation Plans to the Consolidated Financial Statements of the Corporation’s 2020 Annual Report on Form 10-K.

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 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, 2021, 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 2020 Annual Report on Form 10-K . The Corporation accounts for certain financial instruments under the fair value option. For more information, see Note 15 – Fair Value Option . Recurring Fair Value Assets and liabilities carried at fair value on a recurring basis at March 31, 2021 and December 31, 2020, including financial instruments that the Corporation accounts for under the fair value option, are summarized in the following tables.

Accounting Policies [Abstract]
Principles of Consolidation	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.
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. Actual 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, and related notes thereto, of the Corporation’s 2020 Annual Report on Form 10-K.

Gains and Losses on Derivatives Designated as Fair Value Hedges	The table below summarizes information related to fair value hedges for the three months ended March 31, 2021 and 2020. Gains and Losses on Derivatives Designated as Fair Value Hedges Three Months Ended March 31 2021 2020 (Dollars in millions) Derivative Hedged Item Derivative Hedged Item Interest rate risk on long-term debt (1) $ (8,063) $ 8,002 $ 10,334 $ (10,276) Interest rate and foreign currency risk on long-term debt (2) (28) 26 505 (491) Interest rate risk on available-for-sale securities (3) 5,241 (5,150) (350) 342 Total $ (2,850) $ 2,878 $ 10,489 $ (10,425) (1) Amounts are recorded in interest expense in the Consolidated Statement of Income. (2) For the three months ended March 31, 2021 and 2020, the derivative amount includes gains (losses) of $(34) million and $734 million in interest expense, $8 million and $(241) million in market making and similar activities, and $(2) million and $12 million in accumulated other comprehensive income (OCI), respectively. Line item totals are in the Consolidated Statement of Income and on the Consolidated Balance Sheet. (3) Amounts are recorded in interest income in the Consolidated Statement of Income.
Schedule of Derivative Instruments in Statement of Financial Position, Fair Value	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 and Liabilities March 31, 2021 December 31, 2020 (Dollars in millions) Carrying Value Cumulative Fair Value Adjustments (1) Carrying Value Cumulative Fair Value Adjustments (1) Long-term debt (2) $ 143,897 $ 2,304 $ 150,556 $ 8,910 Available-for-sale debt securities (2, 3, 4) 152,388 (4,881) 116,252 114 Trading account assets (5) 660 — 427 15 (1) Increase (decrease) to carrying value. (2) At March 31, 2021 and December 31, 2020, the cumulative fair value adjustments remaining on long-term debt and available-for-sale debt securities from discontinued hedging relationships resulted in an increase in the related liability of $2.1 billion and $3.7 billion and a decrease in the related asset of $71 million and $69 million, which are being amortized over the remaining contractual life of the de-designated hedged items. (3) These amounts include the amortized cost of the prepayable financial assets used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship (i.e. last-of-layer hedging relationship). At March 31, 2021 and December 31, 2020, the amortized cost of the closed portfolios used in these hedging relationships was $30.5 billion and $34.6 billion, of which $7.0 billion was designated in the last-of-layer hedging relationship at both dates. At March 31, 2021, the cumulative adjustment associated with these hedging relationships was a decrease of $115 million. At December 31, 2020, the cumulative adjustment was insignificant. (4) Carrying value represents amortized cost. (5) Represents hedging activities related to precious metals inventory.
Cash Flow and Net Investment Hedges	The table below summarizes certain information related to cash flow hedges and net investment hedges for the three months ended March 31, 2021 and 2020. Of the $688 million after-tax net loss ($917 million pretax) on derivatives in accumulated OCI at March 31, 2021, gains of $220 million after-tax ($294 million pretax) related to both open and terminated cash flow hedges are expected to be reclassified into earnings in the next 12 months. These net gains reclassified into earnings are expected to primarily increase 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 3 years, with a maximum length of time for certain forecasted transactions of 15 years.
