Coronavirus Disease
The Corporation has been, and continues to be, impacted by the Coronavirus Disease 2019 (COVID-19) pandemic (the pandemic). In an attempt to contain the spread and impact of the pandemic, travel bans and restrictions, quarantines, shelter-in-place orders and other limitations on business activity have
been implemented. Additionally, there has been a decline in global economic activity, reduced U.S. and global economic output and a deterioration in macroeconomic conditions in the U.S. and globally. This has resulted in, among other things, higher rates of unemployment and underemployment and caused volatility and disruptions in the global financial markets during 2020, including the energy and commodity markets.
In response to the pandemic, the Corporation has been taking a proactive role in addressing the impact of the pandemic on its employees, its operations, its clients and the community, including the implementation of protocols and processes to execute its business continuity plans and help protect its employees and support its clients. The Corporation is managing its response to the pandemic according to its Enterprise Response Framework, which invokes centralized management of the crisis event and the integration of the Corporation’s enterprise-wide response.
Although some restrictive measures have been eased in certain areas, many restrictive measures remain in place or have been reinstated, and in some cases additional restrictive measures are being or may need to be implemented in light of the increase in COVID-19 cases in recent months in the U.S. and in many other regions of the world. Businesses, market participants, our counterparties and clients, and the U.S. and global economies have been negatively impacted and are likely to remain so for an extended period of time, as there remains significant uncertainty about the magnitude and duration of the pandemic and the timing and strength of an economic recovery. For more information regarding COVID-19, see Item 1A. Risk Factors – Coronavirus Disease on page 7 and Executive Summary – Recent Developments – COVID-19 Pandemic in the MD&A on page 25.
Segments
Through our various bank and nonbank subsidiaries throughout the U.S. and in international markets, we provide a diversified range of banking and nonbank financial services and products through four business segments: Consumer Banking, Global Wealth & Investment Management (GWIM), Global Banking and Global Markets, with the remaining operations recorded in All Other. Additional information related to our business segments and the products and services they provide is included in the information set forth on pages 36 through 46 of Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) and Note 23 – Business Segment Information to the Consolidated Financial Statements.
Competition
We operate in a highly competitive environment. Our competitors include banks, thrifts, credit unions, investment banking firms, investment advisory firms, brokerage firms, investment companies, insurance companies, mortgage banking companies, credit card issuers, mutual fund companies, hedge funds, private equity firms, and e-commerce and other internet-based companies. We compete with some of these competitors globally and with others on a regional or product specific basis.
Competition is based on a number of factors including, among others, customer service, quality and range of products and services offered, price, reputation, interest rates on loans and deposits, lending limits and customer convenience. Our ability to continue to compete effectively also depends in large part on our ability to attract new employees and retain and

motivate our existing employees, while managing compensation and other costs.
Human Capital Resources
We strive to make Bank of America a great place to work for our employees. We value our employees and seek to establish and maintain human resource policies that are consistent with our core values and that help realize the power of our people. Our Board and its committees, including the Compensation and Human Capital, Audit, Enterprise Risk, and Corporate Governance, ESG and Sustainability Committees, provide oversight of our human capital management strategies, programs and practices. The Corporation’s senior management provides regular briefings on human capital matters to the Board and its Committees to facilitate the Board’s oversight.
At December 31, 2020 and 2019, the Corporation employed approximately 213,000 and 208,000 employees, of which 82 percent were located in the U.S. at both dates. None of our U.S. employees are subject to a collective bargaining agreement. Additionally, in 2020 and 2019, the Corporation’s compensation and benefits expense was $32.7 billion and $32.0 billion, or 59 percent and 58 percent, of total noninterest expense.
Diversity and Inclusion
The Corporation’s commitment to diversity and inclusion starts at the top of the Corporation with oversight from our Board and CEO. The Corporation’s senior management sets the diversity and inclusion goals of the Corporation, and the Chief Human Resources Officer and Chief Diversity & Inclusion Officer partner with our CEO and senior management to drive our diversity and inclusion strategy, programs, initiatives and policies. The Global Diversity and Inclusion Council, which consists of senior executives from every line of business and is chaired by our CEO, has been in place for over 20 years. The Council sponsors and supports business, operating unit and regional diversity and inclusion councils to ensure alignment to enterprise diversity strategies and goals.
Our practices and policies have resulted in strong representation across the Corporation where our broad employee population mirrors the clients and communities we serve. We have a Board and senior management team that are 47 percent and 50 percent racially, ethnically and gender diverse. As of December 31, 2020, over 50 percent of employees were women, and, among U.S.-based employees, nearly 48 percent were people of color, 14 percent were Black/African American and 19 percent were Hispanic/Latino. As of December 31, 2020, the Corporation’s top three management levels in relation to the CEO were composed of more than 42 percent women and nearly 20 percent people of color. These workforce diversity metrics are reported regularly to the senior management team and to the Board and are publicly disclosed on our website.
We invest in our leadership by offering a range of development programs and resources that allow employees to develop and progress in their careers. We reinforce our commitment to diversity and inclusion by investing internally in our employee networks and by facilitating conversations with employees about racial, social and economic issues. Further, we partner with various external organizations, which focus on advancing diverse talent. We also have practices in place for attracting and retaining diverse talent, including campus recruitment. For example, in 2020, approximately 45 percent of our campus hires were women, and, in the U.S., approximately 54 percent were people of color.
Employee Engagement and Talent Retention
As part of our ongoing efforts to make the Corporation a great place to work, we have conducted a confidential annual Employee Engagement Survey (Survey) for nearly two decades. The Survey results are reviewed by the Board and senior management and used to assist in reviewing the Corporation’s human capital strategies, programs and practices. In 2020, more than 90 percent of the Corporation’s employees participated in the Survey, and our Employee Engagement Index, an overall measure of employee satisfaction with the Corporation, was 91 percent. In 2020, we also had historically low turnover among our employees of seven percent.
Fair and Equitable Compensation
The Corporation is committed to racial and gender pay equity by striving to fairly and equitably compensate all of our employees. We maintain robust policies and practices that reinforce our commitment, including reviews with oversight from our Board and senior management. In 2020, our review covered our regional hubs (U.S., U.K., France, Ireland, Hong Kong, and Singapore) and India and showed that compensation received by women, on average, was greater than 99 percent of that received by men in comparable positions and, in the U.S., compensation received by people of color was, on average, greater than 99 percent of that received by teammates who are not people of color in comparable positions.
We also strive to pay our employees fairly based on market rates for their roles, experience and how they perform, and we regularly benchmark against other companies both within and outside our industry to help ensure our pay is competitive. In the first quarter of 2020, we raised our minimum hourly wage for U.S. employees to $20 per hour, which is above all governmental minimum wage levels in all jurisdictions in which we operate in the U.S.
Health and Wellness – 2020 Focus
The Corporation also is committed to supporting employees’ physical, emotional and financial wellness by offering flexible and competitive benefits, including comprehensive health and insurance benefits and wellness resources. In 2020, we took steps to support our employees during the ongoing health crisis resulting from the pandemic, including monitoring guidance from the U.S. Centers for Disease Control and Prevention, medical boards and health authorities and sharing such guidance with our employees. In addition, as a result of the pandemic we transitioned to a work-from-home posture for the substantial majority of our employees and provided various benefits and resources related to the pandemic, including the implementation of child and adult care solutions, offering no-cost COVID-19 testing and mental health resources and additional support for teammates who work in the office, such as transportation and meal subsidies. We continue to engage with state and national governments to understand their vaccination plans for essential workers, including the extent to which that may include some of our employees, and with our employees to educate them about vaccines and the importance of being vaccinated. For more information on our response to the pandemic, including with respect to human capital measures, see Executive Summary – Recent Developments – COVID-19 Pandemic on page 25.
Government Supervision and Regulation
The following discussion describes, among other things, elements of an extensive regulatory framework applicable to BHCs, financial holding companies, banks and broker-dealers, including specific information about Bank of America.
3 Bank of America


We are subject to an extensive regulatory framework applicable to BHCs, financial holding companies and banks and other financial services entities. U.S. federal regulation of banks, BHCs and financial holding companies is intended primarily for the protection of depositors and the Deposit Insurance Fund (DIF) rather than for the protection of shareholders and creditors.
As a registered financial holding company and BHC, the Corporation is subject to the supervision of, and regular inspection by, the Board of Governors of the Federal Reserve System (Federal Reserve). Our U.S. bank subsidiaries (the Banks), organized as national banking associations, are subject to regulation, supervision and examination by the Office of the Comptroller of the Currency (OCC), the Federal Deposit Insurance Corporation (FDIC) and the Federal Reserve. In addition, the Federal Reserve and the OCC have adopted guidelines that establish minimum standards for the design, implementation and board oversight of BHCs’ and national banks’ risk governance frameworks. U.S. financial holding companies, and the companies under their control, are permitted to engage in activities considered “financial in nature” as defined by the Gramm-Leach-Bliley Act and related Federal Reserve interpretations. The Corporation's status as a financial holding company is conditioned upon maintaining certain eligibility requirements for both the Corporation and its U.S. depository institution subsidiaries, including minimum capital ratios, supervisory ratings and, in the case of the depository institutions, at least satisfactory Community Reinvestment Act ratings. Failure to be an eligible financial holding company could result in the Federal Reserve limiting Bank of America's activities, including potential acquisitions.
The scope of the laws and regulations and the intensity of the supervision to which we are subject have increased over the past several years, beginning with the response to the financial crisis, as well as other factors such as technological and market changes. In addition, the banking and financial services sector is subject to substantial regulatory enforcement and fines. Many of these changes have occurred as a result of the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the Financial Reform Act). We cannot assess whether there will be any additional major changes in the regulatory environment and expect that our business will remain subject to continuing and extensive regulation and supervision.
We are also subject to various other laws and regulations, as well as supervision and examination by other regulatory agencies, all of which directly or indirectly affect our entities and management and our ability to make distributions to shareholders. For instance, our broker-dealer subsidiaries are subject to both U.S. and international regulation, including supervision by the SEC, Financial Industry Regulatory Authority and New York Stock Exchange, among others; our futures commission merchant subsidiaries supporting commodities and derivatives businesses in the U.S. are subject to regulation by and supervision of the U.S. Commodity Futures Trading Commission (CFTC), National Futures Association, the Chicago Mercantile Exchange and in the case of the Banks, certain banking regulators; our insurance activities are subject to licensing and regulation by state insurance regulatory agencies; and our consumer financial products and services are regulated by the Consumer Financial Protection Bureau (CFPB).
Our non-U.S. businesses are also subject to extensive regulation by various non-U.S. regulators, including governments, securities exchanges, prudential regulators, central banks and other regulatory bodies, in the jurisdictions in which those businesses operate. For example, our financial
services entities in the United Kingdom (U.K.), Ireland and France are subject to regulation by the Prudential Regulatory Authority and Financial Conduct Authority, the European Central Bank and Central Bank of Ireland, and the Autorité de Contrôle Prudentiel et de Résolution and Autorité des Marchés Financiers, respectively.
Source of Strength
Under the Financial Reform Act and Federal Reserve policy, BHCs are expected to act as a source of financial strength to each subsidiary bank and to commit resources to support each such subsidiary. Similarly, under the cross-guarantee provisions of the Federal Deposit Insurance Corporation Improvement Act of 1991 (FDICIA), in the event of a loss suffered or anticipated by the FDIC, either as a result of default of a bank subsidiary or related to FDIC assistance provided to such a subsidiary in danger of default, the affiliate banks of such a subsidiary may be assessed for the FDIC’s loss, subject to certain exceptions.
Transactions with Affiliates
Pursuant to Section 23A and 23B of the Federal Reserve Act, as implemented by the Federal Reserve’s Regulation W, the Banks are subject to restrictions that limit certain types of transactions between the Banks and their nonbank affiliates. In general, U.S. banks are subject to quantitative and qualitative limits on extensions of credit, purchases of assets and certain other transactions involving their nonbank affiliates. Additionally, transactions between U.S. banks and their nonbank affiliates are required to be on arm’s length terms and must be consistent with standards of safety and soundness.
Deposit Insurance
Deposits placed at U.S. domiciled banks are insured by the FDIC, subject to limits and conditions of applicable law and the FDIC’s regulations. Pursuant to the Financial Reform Act, FDIC insurance coverage limits are $250,000 per customer. All insured depository institutions are required to pay assessments to the FDIC in order to fund the DIF.
The FDIC is required to maintain at least a designated minimum ratio of the DIF to insured deposits in the U.S. The FDIC adopted regulations that establish a long-term target DIF ratio of greater than two percent. As of the date of this report, the DIF ratio is below this required target, and the FDIC has adopted a restoration plan that may result in increased deposit insurance assessments. Deposit insurance assessment rates are subject to change by the FDIC and will be impacted by the overall economy and the stability of the banking industry as a whole. For more information regarding deposit insurance, see Item 1A. Risk Factors – Regulatory, Compliance and Legal on page 16.
Capital, Liquidity and Operational Requirements
As a financial holding company, we and our bank subsidiaries are subject to the regulatory capital and liquidity rules issued by the Federal Reserve and other U.S. banking regulators, including the OCC and the FDIC. These rules are complex and are evolving as U.S. and international regulatory authorities propose and enact amendments to these rules. The Corporation seeks to manage its capital position to maintain sufficient capital to satisfy these regulatory rules and to support our business activities. These continually evolving rules are likely to influence our planning processes and may require additional regulatory capital and liquidity, as well as impose additional operational and compliance costs on the Corporation.
For more information on regulatory capital rules, capital composition and pending or proposed regulatory capital
Bank of America 4


changes, see Capital Management on page 50, and Note 16 – Regulatory Requirements and Restrictions to the Consolidated Financial Statements, which are incorporated by reference in this Item 1.
Distributions
We are subject to various regulatory policies and requirements relating to capital actions, including payment of dividends and common stock repurchases. For instance, Federal Reserve regulations require major U.S. BHCs to submit a capital plan as part of an annual Comprehensive Capital Analysis and Review (CCAR).
Our ability to pay dividends and make common stock repurchases depends in part on our ability to maintain regulatory capital levels above minimum requirements plus buffers and non-capital standards established under the FDICIA. To the extent that the Federal Reserve increases our stress capital buffer (SCB), global systemically important bank (G-SIB) surcharge or countercyclical capital buffer, our returns of capital to shareholders could decrease. As part of its CCAR, the Federal Reserve conducts stress testing on parts of our business using hypothetical economic scenarios prepared by the Federal Reserve. Those scenarios may affect our CCAR stress test results, which may impact the level of our SCB. Additionally, the Federal Reserve may impose limitations or prohibitions on taking capital actions such as paying or increasing common stock dividends or repurchasing common stock. For example, as a result of the economic uncertainty resulting from the pandemic, the Federal Reserve required that during the second half of 2020, all large banks, including the Corporation, suspend share repurchase programs, except for repurchases to offset shares awarded under equity-based compensation plans, and limit common stock dividends to existing rates that did not exceed the average of the last four quarters' net income. In the first quarter of 2021, the Federal Reserve lifted the suspension of share repurchase programs and permitted large banks to pay common stock dividends and to repurchase shares in an amount that, when combined with dividends paid, does not exceed the average of net income over the last four quarters.
If the Federal Reserve finds that any of our Banks are not “well-capitalized” or “well-managed,” we would be required to enter into an agreement with the Federal Reserve to comply with all applicable capital and management requirements, which may contain additional limitations or conditions relating to our activities. Additionally, the applicable federal regulatory authority is authorized to determine, under certain circumstances relating to the financial condition of a bank or BHC, that the payment of dividends would be an unsafe or unsound practice and to prohibit payment thereof.
For more information regarding the requirements relating to the payment of dividends, including the minimum capital requirements, see Note 13 – Shareholders’ Equity and Note 16 – Regulatory Requirements and Restrictions to the Consolidated Financial Statements.
Many of our subsidiaries, including our bank and broker-dealer subsidiaries, are subject to laws that restrict dividend payments, or authorize regulatory bodies to block or reduce the flow of funds from those subsidiaries to the parent company or other subsidiaries. The rights of the Corporation, our shareholders and our creditors to participate in any distribution of the assets or earnings of our subsidiaries is further subject to the prior claims of creditors of the respective subsidiaries.

Resolution Planning
As a BHC with greater than $250 billion of assets, the Corporation is required by the Federal Reserve and the FDIC to periodically submit a plan for a rapid and orderly resolution in the event of material financial distress or failure.
Such resolution plan is intended to be a detailed roadmap for the orderly resolution of the BHC, including the continued operations or solvent wind down of its material entities, pursuant to the U.S. Bankruptcy Code under one or more hypothetical scenarios assuming no extraordinary government assistance.
If both the Federal Reserve and the FDIC determine that the BHC’s plan is not credible, the Federal Reserve and the FDIC may jointly impose more stringent capital, leverage or liquidity requirements or restrictions on growth, activities or operations. A summary of our plan is available on the Federal Reserve and FDIC websites.
The FDIC also requires the submission of a resolution plan for Bank of America, National Association (BANA), which must describe how the insured depository institution would be resolved under the bank resolution provisions of the Federal Deposit Insurance Act. A description of this plan is available on the FDIC’s website.
We continue to make substantial progress to enhance our resolvability, including simplifying our legal entity structure and business operations, and increasing our preparedness to implement our resolution plan, both from a financial and operational standpoint.
Across international jurisdictions, resolution planning is the responsibility of national resolution authorities (RA). Among those, the jurisdictions of most impact to the Corporation are the requirements associated with subsidiaries in the U.K., Ireland and France, where rules have been issued requiring the submission of significant information about locally-incorporated subsidiaries (including information on intra-group dependencies, legal entity separation and barriers to resolution) as well as the Corporation’s banking branches located in those jurisdictions that are deemed to be material for resolution planning purposes. As a result of the RA's review of the submitted information, we could be required to take certain actions over the next several years that could increase operating costs and potentially result in the restructuring of certain businesses and subsidiaries.
For more information regarding our resolution plan, see Item 1A. Risk Factors – Liquidity on page 9.
Insolvency and the Orderly Liquidation Authority
Under the Federal Deposit Insurance Act, the FDIC may be appointed receiver of an insured depository institution if it is insolvent or in certain other circumstances. In addition, under the Financial Reform Act, when a systemically important financial institution (SIFI) such as the Corporation is in default or danger of default, the FDIC may be appointed receiver in order to conduct an orderly liquidation of such institution. In the event of such appointment, the FDIC could, among other things, invoke the orderly liquidation authority, instead of the U.S. Bankruptcy Code, if the Secretary of the Treasury makes certain financial distress and systemic risk determinations. The orderly liquidation authority is modeled in part on the Federal Deposit Insurance Act, but also adopts certain concepts from the U.S. Bankruptcy Code.
The orderly liquidation authority contains certain differences from the U.S. Bankruptcy Code. For example, in certain circumstances, the FDIC could permit payment of obligations it determines to be systemically significant (e.g., short-term
5 Bank of America


creditors or operating creditors) in lieu of paying other obligations (e.g., long-term creditors) without the need to obtain creditors’ consent or prior court review. The insolvency and resolution process could also lead to a large reduction or total elimination of the value of a BHC’s outstanding equity, as well as impairment or elimination of certain debt.
Under the FDIC’s “single point of entry” strategy for resolving SIFIs, the FDIC could replace a distressed BHC with a bridge holding company, which could continue operations and result in an orderly resolution of the underlying bank, but whose equity is held solely for the benefit of creditors of the original BHC.
Furthermore, the Federal Reserve requires that BHCs maintain minimum levels of long-term debt required to provide adequate loss absorbing capacity in the event of a resolution.
For more information regarding our resolution, see Item 1A. Risk Factors – Liquidity on page 9.
Limitations on Acquisitions
The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 permits a BHC to acquire banks located in states other than its home state without regard to state law, subject to certain conditions, including the condition that the BHC, after and as a result of the acquisition, controls no more than 10 percent of the total amount of deposits of insured depository institutions in the U.S. and no more than 30 percent or such lesser or greater amount set by state law of such deposits in that state. At June 30, 2020, we held greater than 10 percent of the total amount of deposits of insured depository institutions in the U.S.
In addition, the Financial Reform Act restricts acquisitions by a financial institution if, as a result of the acquisition, the total liabilities of the financial institution would exceed 10 percent of the total liabilities of all financial institutions in the U.S. At June 30, 2020, our liabilities did not exceed 10 percent of the total liabilities of all financial institutions in the U.S.
The Volcker Rule
The Volcker Rule prohibits insured depository institutions and companies affiliated with insured depository institutions (collectively, banking entities) from engaging in short-term proprietary trading of certain securities, derivatives, commodity futures and options for their own account. The Volcker Rule also imposes limits on banking entities’ investments in, and other relationships with, hedge funds and private equity funds. The Volcker Rule provides exemptions for certain activities, including market making, underwriting, hedging, trading in government obligations, insurance company activities and organizing and offering hedge funds and private equity funds. The Volcker Rule also clarifies that certain activities are not prohibited, including acting as agent, broker or custodian. A banking entity with significant trading operations, such as the Corporation, is required to maintain a detailed compliance program to comply with the restrictions of the Volcker Rule.
Derivatives
Our derivatives operations are subject to extensive regulation globally. These operations are subject to regulation under the Financial Reform Act, the European Union (EU) Markets in Financial Instruments Directive and Regulation, the European Market Infrastructure Regulation, analogous U.K. regulatory regimes and similar regulatory regimes in other jurisdictions, that regulate or will regulate the derivatives markets in which we operate by, among other things: requiring clearing and exchange trading of certain derivatives; imposing new capital, margin, reporting, registration and business conduct requirements for certain market participants; imposing position limits on certain
over-the-counter (OTC) derivatives; and imposing derivatives trading transparency requirements. Regulations of derivatives are already in effect in many markets in which we operate.
In addition, many G-20 jurisdictions, including the U.S., U.K., Germany and Japan, have adopted resolution stay regulations to address concerns that the close-out of derivatives and other financial contracts in resolution could impede orderly resolution of G-SIBs, and additional jurisdictions are expected to follow suit. Generally, these resolution stay regulations require amendment of certain financial contracts to provide for contractual recognition of stays of termination rights under various statutory resolution regimes and a stay on the exercise of cross-default rights based on an affiliate’s entry into insolvency proceedings. As resolution stay regulations of a particular jurisdiction applicable to us go into effect, we amend impacted financial contracts in compliance with such regulations either as a regulated entity or as a counterparty facing a regulated entity in such jurisdiction.
Consumer Regulations
Our consumer businesses are subject to extensive regulation and oversight by federal and state regulators. Certain federal consumer finance laws to which we are subject, including the Equal Credit Opportunity Act, Home Mortgage Disclosure Act, Electronic Fund Transfer Act, Fair Credit Reporting Act, Real Estate Settlement Procedures Act, Truth in Lending Act and Truth in Savings Act, are enforced by the CFPB. Other federal consumer finance laws, such as the Servicemembers Civil Relief Act, are enforced by the OCC.
Privacy and Information Security
We are subject to many U.S. federal, state and international laws and regulations governing requirements for maintaining policies and procedures regarding the disclosure, use and protection of the non-public confidential information of our customers and employees. The Gramm-Leach-Bliley Act requires us to periodically disclose Bank of America’s privacy policies and practices relating to sharing such information and enables retail customers to opt out of our ability to share information with unaffiliated third parties, under certain circumstances. The Gramm-Leach-Bliley Act and other laws also require us to implement a comprehensive information security program that includes administrative, technical and physical safeguards to provide the security and confidentiality of customer records and information. Security and privacy policies and procedures for the protection of personal and confidential information are in effect across all businesses and geographic locations.
Other laws and regulations, at the international, federal and state level, impact our ability to share certain information with affiliates and non-affiliates for marketing and/or non-marketing purposes, or contact customers with marketing offers and establish certain rights of consumers in connection with their personal information. For example, California’s Consumer Privacy Act (CCPA), which went into effect in January 2020, as modified by the California Privacy Rights Act (CPRA), provides consumers with the right to know what personal data is being collected, know whether their personal data is sold or disclosed and to whom and opt out of the sale of their personal data, among other rights. In addition, in the EU, the General Data Protection Regulation (GDPR) replaced the Data Protection Directive and related implementing national laws in its member states. The CCPA's, CPRA's and GDPR’s impact on the Corporation was assessed and addressed through comprehensive compliance implementation programs. These existing and evolving legal requirements in the U.S. and abroad,
Bank of America 6


as well as court proceedings and changing guidance from regulatory bodies with respect to the validity of cross-border data transfer mechanisms from the EU, continue to lend uncertainty to privacy compliance globally.
Item 1A. Risk Factors
The discussion below addresses the material factors of which we are currently aware that could affect our businesses, results of operations and financial condition. However, other factors not currently known to us or that we currently deem immaterial could also adversely affect our businesses, results of operations and financial condition. Therefore, the risk factors below should not be considered all of the potential risks that we may face. For more information on how we manage risks, see Managing Risk in the MD&A on page 47. For more information about the risks contained in the Risk Factors section, see Item 1. Business on page 2, MD&A on page 24 and Notes to Consolidated Financial Statements on page 101.
Coronavirus Disease
The effects of the pandemic have adversely affected, and are expected to continue to adversely affect, our businesses and results of operations, and its duration and future impacts on the economy and our businesses, results of operations and financial condition remain uncertain.
The negative economic conditions arising from the pandemic negatively impacted our financial results during 2020 in various respects, including contributing to increases in our allowance and provision for credit losses and noninterest expense. These negative economic conditions may have a continued adverse effect on our businesses and results of operations, which could include: decreased demand for and use of our products and services; protracted periods of historically low interest rates; lower fees, including asset management fees; lower sales and trading revenue due to decreased market liquidity resulting from heightened volatility; higher levels of uncollectible reversed charges in our merchant services business; increased noninterest expense, including operational losses; and increased credit losses due to our customers' and clients' inability to fulfill contractual obligations and deterioration in the financial condition of our consumer and commercial borrowers, which may vary by region, sector or industry, that may increase our provision for credit losses and net charge-offs. Our provision for credit losses and net charge-offs may also continue to be impacted by volatility in the energy and commodity markets. Additionally, our liquidity and/or regulatory capital could be adversely impacted by customers’ withdrawal of deposits, volatility and disruptions in the capital and credit markets, volatility in foreign exchange rates and customer draws on lines of credit. Continued adverse macroeconomic conditions could also result in potential downgrades to our credit ratings, negative impacts to regulatory capital and liquidity and further restrictions on dividends and/or common stock repurchases.
If we become unable to operate our businesses from remote locations including, for example, because of an internal or external failure of our information technology infrastructure, we experience increased rates of employee illness or unavailability, or governmental restrictions are placed on our employees or operations, this could adversely affect our business continuity status and result in disruption to our businesses. Additionally, we rely on third parties who could experience adverse effects on their business continuity and business interruptions, which could increase our risks and adversely impact our businesses.
There can be no assurance that current or future governmental fiscal and monetary relief programs will stimulate
the global economy or avert negative economic or market conditions. Our participation in such programs could result in reputational harm and government actions and proceedings, and has resulted in, and may continue to result in, litigation, including class actions. Such actions may result in judgments, settlements, penalties, and fines. Our participation in such programs has also resulted and may continue to result in operational losses, including from the Paycheck Protection Program (PPP) and processing unemployment insurance.
We continue to closely monitor the pandemic and related risks as they evolve globally and in the U.S. The magnitude and duration of the pandemic and its future direct and indirect effects on the global economy and our businesses, results of operations and financial condition are highly uncertain and depend on future developments that cannot be predicted, including the likelihood of further surges of COVID-19 cases and the spread of more easily communicable variants of COVID-19, the timing and availability of effective medical treatments and vaccines, future actions taken by governmental authorities, including additional stimulus legislation, and/or other third parties in response to the pandemic. The pandemic may cause prolonged global or national negative economic conditions or longer lasting effects on economic conditions than currently exist, which could have a material adverse effect on our businesses, results of operations and financial condition.
Market
Our business and results of operations may be adversely affected by the financial markets, fiscal, monetary, and regulatory policies, and economic conditions generally.
General economic, political, social and health conditions in the U.S. and in one or more countries abroad affect markets in the U.S. and abroad and our business. In particular, markets in the U.S. or abroad may be affected by the level and volatility of interest rates, availability and market conditions of financing, unexpected changes in gross domestic product (GDP), economic growth or its sustainability, inflation, consumer spending, employment levels, wage stagnation, federal government shutdowns, developments related to the federal debt ceiling, energy prices, home prices, bankruptcies, a default by a significant market participant, fluctuations or other significant changes in both debt and equity capital markets and currencies, liquidity of the global financial markets, the growth of global trade and commerce, trade policies, the availability and cost of capital and credit, disruption of communication, transportation or energy infrastructure and investor sentiment and confidence. Additionally, global markets, including energy and commodity markets, may be adversely affected by the current or anticipated impact of climate change, extreme weather events or natural disasters, the emergence of widespread health emergencies or pandemics, cyber attacks or campaigns, military conflict, terrorism or other geopolitical events. Market fluctuations may impact our margin requirements and affect our business liquidity. Also, any sudden or prolonged market downturn in the U.S. or abroad, as a result of the above factors or otherwise, could result in a decline in net interest income and noninterest income and adversely affect our results of operations and financial condition, including capital and liquidity levels. For example, the global markets, including the energy and commodity markets, experienced significant volatility and disruption as a result of the uncertainty and economic impact of the pandemic. Further uncertainty and ongoing developments in connection with the pandemic, including its further spread, changing consumer and business behaviors, government restrictions in an effort to control the virus and timing and availability of effective medical treatments and vaccines, could

result in further market volatility and disruptions globally and continue to adversely impact macroeconomic conditions.
Actions taken by the Federal Reserve, including changes in its target funds rate, balance sheet management, and lending facilities, and other central banks are beyond our control and difficult to predict. These actions can affect interest rates and the value of financial instruments and other assets and liabilities, and impact our borrowers. The continued protracted period of lower interest rates has resulted in lower revenue through lower net interest income, which has adversely affected our results of operations. Additional periods of lower interest rates or a move to negative interest rates in the U.S., could have a further adverse impact on our net interest income and results of operations. Uncertainty or ongoing developments in connection with the U.K.’s exit from the EU, and the resulting impact on the financial markets and regulations in relevant jurisdictions, could negatively impact our revenues and ongoing operations in Europe and other jurisdictions.
Changes to existing U.S. laws and regulatory policies, including those related to financial regulation, taxation, international trade, fiscal policy and healthcare, may adversely impact U.S. or global economic activity and our customers', our counterparties' and our earnings and operations. For example, additional fiscal stimulus and rising debt levels, in the U.S. and abroad, in response to the ongoing pandemic could affect macroeconomic conditions, market liquidity conditions, and interest rates. Significant fiscal policy changes and/or initiatives, including as a result of the change in the U.S. presidential administration and Congress, may also increase uncertainty surrounding the formulation and direction of U.S. monetary policy and volatility of interest rates. Higher U.S. interest rates relative to other major economies could increase the likelihood of a more volatile and appreciating U.S. dollar. Changes, or proposed changes, to certain U.S. trade and international investment policies, particularly with important trading partners (including China and the EU) have negatively impacted and may continue to negatively impact financial markets, disrupt world trade and commerce and lead to trade retaliation, including through the use of tariffs, foreign exchange measures or the large-scale sale of U.S. Treasury Bonds. Further, the use of tariffs among countries not directly involving the U.S. could spread and could damage our customers directly and indirectly.
Any of these developments could adversely affect our consumer and commercial businesses, our customers, our securities and derivatives portfolios, including the risk of lower re-investment rates within those portfolios, our level of charge-offs and provision for credit losses, the carrying value of our deferred tax assets, our capital levels, our liquidity and our results of operations. Additionally, the uncertainty related to the transition from Interbank Offered Rates (IBORs) and other benchmark rates to alternative reference rates (ARRs) could negatively impact markets globally and our business, and/or magnify any negative impact of the above referenced factors on our business, customers and results of operations.
Increased market volatility and adverse changes in financial or capital market conditions may increase our market risk.
Our liquidity, competitive position, business, results of operations and financial condition are affected by market risks such as changes in interest and currency exchange rates, fluctuations in equity and futures prices, lower trading volumes and prices of securitized products, the implied volatility of interest rates and credit spreads and other economic and business factors. These market risks may adversely affect, among other things, the value of our on- and off-balance sheet
securities, trading assets and other financial instruments, the cost of debt capital and our access to credit markets, the value of assets under management (AUM), fee income relating to AUM, customer allocation of capital among investment alternatives, the volume of client activity in our trading operations, investment banking fees, the general profitability and risk level of the transactions in which we engage and our competitiveness with respect to deposit pricing. For example, the value of certain of our assets is sensitive to changes in market interest rates. If the Federal Reserve or a non-U.S. central bank changes or signals a change in monetary policy, market interest rates could be affected, which could adversely impact the value of such assets. Changes to fiscal policy, including rapid expansion of U.S. federal deficit spending and resultant debt issuance, could also affect market interest rates. In addition, the low interest rate environment and a flat or inverted yield curve has had and could continue to have a negative impact on our results of operations, including on future revenue and earnings growth.
We use various models and strategies to assess and control our market risk exposures, but those are subject to inherent limitations. In times of market stress or other unforeseen circumstances, previously uncorrelated indicators may become correlated and vice versa. These types of market movements may limit the effectiveness of our hedging strategies and cause us to incur significant losses. These changes in correlation can be exacerbated where other market participants are using risk or trading models with assumptions or algorithms similar to ours. In these and other cases, it may be difficult to reduce our risk positions due to activity of other market participants or widespread market dislocations, including circumstances where asset values are declining significantly or no market exists for certain assets. To the extent that we own securities that do not have an established liquid trading market or are otherwise subject to restrictions on sale or hedging, we may not be able to reduce our positions and therefore reduce our risk associated with such positions.
We may incur losses if the value of assets decline, including due to changes in interest rates and prepayment speeds.
We have a large portfolio of financial instruments, including loans and loan commitments, securities financing agreements, asset-backed secured financings, derivative assets and liabilities, debt securities, marketable equity securities and certain other assets and liabilities that we measure at fair value that are subject to valuation and impairment assessments. We determine these values based on applicable accounting guidance, which for financial instruments measured at fair value, requires an entity to base fair value on exit price and to maximize the use of observable inputs and minimize the use of unobservable inputs in fair value measurements. The fair values of these financial instruments include adjustments for market liquidity, credit quality, funding impact on certain derivatives and other transaction-specific factors, where appropriate.
Gains or losses on these instruments can have a direct impact on our results of operations, unless we have effectively hedged our exposures. Increases in interest rates may result in a decrease in residential mortgage loan originations. In addition, increases in interest rates may adversely impact the fair value of debt securities and, accordingly, for debt securities classified as available for sale, may adversely affect accumulated other comprehensive income and, thus, capital levels. Decreases in interest rates may increase prepayment speeds of certain assets, and therefore may adversely affect net interest income.
Fair values may be impacted by declining values of the underlying assets or the prices at which observable market
Bank of America 8


transactions occur and the continued availability of these transactions or indices. The financial strength of counterparties, with whom we have economically hedged some of our exposure to these assets, also will affect the fair value of these assets. Sudden declines and volatility in the prices of assets may curtail or eliminate trading activities in these assets, which may make it difficult to sell, hedge or value these assets. The inability to sell or effectively hedge assets reduces our ability to limit losses in such positions and the difficulty in valuing assets may increase our risk-weighted assets (RWA), which requires us to maintain additional capital and increases our funding costs. Values of AUM also impact revenues in our wealth management and related advisory businesses for asset-based management and performance fees. Declines in values of AUM can result in lower fees earned for managing such assets.
Liquidity
If we are unable to access the capital markets or continue to maintain deposits, or our borrowing costs increase, our liquidity and competitive position will be negatively affected.
Liquidity is essential to our businesses. We fund our assets primarily with globally sourced deposits in our bank entities, as well as secured and unsecured liabilities transacted in the capital markets. We rely on certain secured funding sources, such as repo markets, which are typically short-term and credit-sensitive in nature. We also engage in asset securitization transactions, including with the government-sponsored enterprises (GSEs), to fund consumer lending activities. Our liquidity could be adversely affected by any inability to access the capital markets, illiquidity or volatility in the capital markets, the decrease in value of eligible collateral or increased collateral requirements (including as a result of credit concerns for short-term borrowing), changes to our relationships with our funding providers based on real or perceived changes in our risk profile, prolonged federal government shutdowns, or changes in regulations, guidance or GSE status that impact our funding avenues or ability to access certain funding sources. Additionally, our liquidity may be negatively impacted by the unwillingness or inability of the Federal Reserve to act as lender of last resort, unexpected simultaneous draws on lines of credit, slower customer payment rates, restricted access to the assets of prime brokerage clients, the withdrawal of or failure to attract customer deposits or invested funds (which could result from customer attrition for higher yields, the desire for more conservative alternatives or our customers’ increased need for cash), increased regulatory liquidity, capital and margin requirements for our U.S. or international banks and their nonbank subsidiaries, changes in patterns of intraday liquidity usage resulting from a counterparty or technology failure or other idiosyncratic event or failure or default by a significant market participant or third party (including clearing agents, custodians or central counterparties (CCPs)). These factors also have the potential to increase our borrowing costs.
Several of these factors may arise due to circumstances beyond our control, such as general market volatility, disruption, shock or stress, the emergence of widespread health emergencies or pandemics, Federal Reserve policy decisions (including fluctuations in interest rates or Federal Reserve balance sheet composition), negative views about the Corporation (including short- and long-term business prospects) or the financial services industry generally or due to a specific news event, changes in the regulatory environment or governmental fiscal or monetary policies (including as a result of the change in the U.S. presidential administration and Congress), actions by credit rating agencies or an operational
problem that affects third parties or us. The impact of these events, whether within our control or not, could include an inability to sell assets or redeem investments, unforeseen outflows of cash, the need to draw on liquidity facilities, the reduction of financing balances and the loss of equity secured funding, debt repurchases to support the secondary market or meet client requests, the need for additional funding for commitments and contingencies and unexpected collateral calls, among other things, the result of which could be increased costs, a liquidity shortfall and/or impact on our liquidity coverage ratio.
Our liquidity and cost of obtaining funding is directly related to prevailing market conditions, including changes in interest and currency exchange rates, fluctuations in equity and futures prices, lower trading volumes and prices of securitized products and our credit spreads. Credit spreads are the amount in excess of the interest rate of U.S. Treasury securities, or other benchmark securities, of a similar maturity that we need to pay to our funding providers. Increases in interest rates and our credit spreads can increase the cost of our funding and result in mark-to-market or credit valuation adjustment exposures. Changes in our credit spreads are market-driven and may be influenced by market perceptions of our creditworthiness. Changes to interest rates and our credit spreads occur continuously and may be unpredictable and highly volatile. We may also experience spread compression as a result of offering higher than expected deposit rates in order to attract and maintain deposits due to increased marketplace rate competition. Additionally, concentrations within our funding profile, such as maturities, currencies or counterparties, can reduce our funding efficiency.
Reduction in our credit ratings could significantly limit our access to funding or the capital markets, increase borrowing costs or trigger additional collateral or funding requirements.
Our borrowing costs and ability to raise funds are directly impacted by our credit ratings. In addition, credit ratings may be important to customers or counterparties when we compete in certain markets and seek to engage in certain transactions, including OTC derivatives. Credit ratings and outlooks are opinions expressed by rating agencies on our creditworthiness and that of our obligations or securities, including long-term debt, short-term borrowings, preferred stock and asset securitizations. Our credit ratings are subject to ongoing review by rating agencies, which consider a number of factors, including our financial strength, performance, prospects and operations and factors not under our control, such as the macroeconomic and geopolitical environment, including the macroeconomic stress caused by the pandemic.
Rating agencies could make adjustments to our credit ratings at any time, and there can be no assurance as to when and whether downgrades will occur. A reduction in certain of our credit ratings could result in a wider credit spread and negatively affect our liquidity, access to credit markets, the related cost of funds, our businesses and certain trading revenues, particularly in those businesses where counterparty creditworthiness is critical. If the short-term credit ratings of our parent company, or bank or broker-dealer subsidiaries, were downgraded by one or more levels, we may suffer the potential loss of access to short-term funding sources such as repo financing, and/or incur increased cost of funds and increased collateral requirements. Under the terms of certain OTC derivative contracts and other trading agreements, if our or our subsidiaries’ credit ratings are downgraded, the counterparties may require additional collateral or terminate these contracts or agreements.
9 Bank of America


While certain potential impacts are contractual and quantifiable, the full consequences of a credit rating downgrade to a financial institution are inherently uncertain, as they depend upon numerous dynamic, complex and inter-related factors and assumptions, including whether any downgrade of a firm’s long-term credit ratings precipitates downgrades to its short-term credit ratings, and assumptions about the potential behaviors of various customers, investors and counterparties.
Bank of America Corporation is a holding company, is dependent on its subsidiaries for liquidity and may be restricted from transferring funds from subsidiaries.
Bank of America Corporation, as the parent company, is a separate and distinct legal entity from our bank and nonbank subsidiaries. We evaluate and manage liquidity on a legal entity basis. Legal entity liquidity is an important consideration as there are legal, regulatory, contractual and other limitations on our ability to utilize liquidity from one legal entity to satisfy the liquidity requirements of another, including the parent company, which could result in adverse liquidity events. The parent company depends on dividends, distributions, loans and other payments from our bank and nonbank subsidiaries to fund dividend payments on our common stock and preferred stock and to fund all payments on our other obligations, including debt obligations. Any inability of our subsidiaries to pay dividends or make payments to us may adversely affect our cash flow and financial condition.
Many of our subsidiaries, including our bank and broker-dealer subsidiaries, are subject to laws that restrict dividend payments, or authorize regulatory bodies to block or reduce the flow of funds from those subsidiaries to the parent company or other subsidiaries. Our bank and broker-dealer subsidiaries are subject to restrictions on their ability to lend or transact with affiliates and to minimum regulatory capital and liquidity requirements, as well as restrictions on their ability to use funds deposited with them in bank or brokerage accounts to fund their businesses. Intercompany arrangements we entered into in connection with our resolution planning submissions could restrict the amount of funding available to the parent company from our subsidiaries under certain adverse conditions.
Additional restrictions on related party transactions, increased capital and liquidity requirements and additional limitations on the use of funds on deposit in bank or brokerage accounts, as well as lower earnings, can reduce the amount of funds available to meet the obligations of the parent company and even require the parent company to provide additional funding to such subsidiaries. Also, regulatory action that requires additional liquidity at each of our subsidiaries could impede access to funds we need to pay our obligations or pay dividends. In addition, our right to participate in a distribution of assets upon a subsidiary’s liquidation or reorganization is subject to prior claims of the subsidiary’s creditors.
Our liquidity and financial condition, and the ability to pay dividends to shareholders and to pay obligations could be materially adversely affected in the event of a resolution.
Bank of America Corporation, our parent holding company, is required to periodically submit a plan to the FDIC and Federal Reserve describing its resolution strategy under the U.S. Bankruptcy Code in the event of material financial distress or failure. In the current plan, Bank of America Corporation’s preferred resolution strategy is a “single point of entry” strategy. This strategy provides that only the parent holding company files for resolution under the U.S. Bankruptcy Code and contemplates providing certain key operating subsidiaries with sufficient capital and liquidity to operate through severe stress and to enable such subsidiaries to continue operating or be wound
down in a solvent manner following a bankruptcy of the parent holding company. Bank of America Corporation has entered into intercompany arrangements resulting in the contribution of most of its capital and liquidity to key subsidiaries. Pursuant to these arrangements, if Bank of America Corporation’s liquidity resources deteriorate so severely that resolution becomes imminent, Bank of America Corporation will no longer be able to draw liquidity from its key subsidiaries, and will be required to contribute its remaining financial assets to a wholly-owned holding company subsidiary, which could materially and adversely affect our liquidity and financial condition and the ability to return capital to shareholders, including through the payment of dividends and repurchase of the Corporation’s common stock, and meet our payment obligations.
If the FDIC and Federal Reserve jointly determine that Bank of America Corporation’s resolution plan is not credible, they could impose more stringent capital, leverage or liquidity requirements or restrictions on our growth, activities or operations. We could also be required to take certain actions that could impose operating costs and could potentially result in the divestiture or restructuring of businesses and subsidiaries.
Additionally, under the Financial Reform Act, when a G-SIB such as Bank of America Corporation is in default or danger of default, the FDIC may be appointed receiver in order to conduct an orderly liquidation of such institution. In the event of such appointment, the FDIC could, among other things, invoke the orderly liquidation authority, instead of the U.S. Bankruptcy Code, if the Secretary of the Treasury makes certain financial distress and systemic risk determinations. In 2013, the FDIC issued a notice describing its preferred “single point of entry” strategy for resolving a G-SIB. Under this approach, the FDIC could replace Bank of America Corporation with a bridge holding company, which could continue operations and result in an orderly resolution of the underlying bank, but whose equity would be held solely for the benefit of our creditors. The FDIC’s “single point of entry” strategy may result in our security holders suffering greater losses than would have been the case under a bankruptcy proceeding or a different resolution strategy.
Credit
Economic or market disruptions and insufficient credit loss reserves may result in a higher provision for credit losses.
A number of our products expose us to credit risk, including loans, letters of credit, derivatives, debt securities, trading account assets and assets held-for-sale. Deterioration in the financial condition of our consumer and commercial borrowers, counterparties or underlying collateral could adversely affect our financial condition and results of operations.
Our credit portfolios may be impacted by global and U.S. macroeconomic and market conditions, events and disruptions, including sustained weakness in GDP, consumer-spending declines, property value declines or asset-price corrections, increasing consumer and corporate leverage, increases in corporate bond spreads, rising or elevated unemployment levels, fluctuations in foreign exchange or interest rates, widespread health emergencies or pandemics, extreme weather events and the impacts of climate change and domestic and global efforts to transition to a low-carbon economy. Significant economic or market stresses and disruptions typically have a negative impact on the business environment and financial markets. Property value declines or asset-price corrections could increase the risk of borrowers or counterparties defaulting or becoming delinquent in their obligations to us, which could increase credit losses. Simultaneous drawdowns on lines of credit and/or an increase in a borrower’s leverage in a
Bank of America 10


weakening economic environment could result in deterioration in our credit portfolio, should borrowers be unable to fulfill competing financial obligations. Credit portfolio deterioration could also be magnified by lending to leveraged borrowers, elevated asset prices or declining property or collateral values unrelated to macroeconomic stress. Increased delinquency and default rates could adversely affect our consumer credit card, home equity and residential mortgage portfolios through increased charge-offs and provision for credit losses.
Beginning in the first quarter of 2020, the pandemic resulted in changes to consumer and business behaviors and restrictions on economic activity, which have negatively impacted the global economy and could continue to negatively impact our consumer and commercial credit portfolios. Accordingly, we increased our allowance for credit losses as a result of the expected macroeconomic impact of COVID-19, which has adversely affected our results of operations. Although the economy, including GDP, and unemployment have improved since the first half of 2020, certain sectors remain significantly impacted (e.g., hospitality, entertainment and travel). As COVID-19 cases have surged in the fourth quarter of 2020 and early 2021, compared to earlier levels, and restrictions on economic activity have been reintroduced in certain geographies, there remains significant uncertainty on what the ultimate impact the pandemic will have on the economy and our allowance for credit losses.
We establish an allowance for credit losses, which includes the allowance for loan and lease losses and the reserve for unfunded lending commitments, based on management's best estimate of lifetime expected credit losses inherent in the Corporation's relevant financial assets. The process to determine the allowance requires us to make difficult and complex judgments, including forecasting how borrowers will perform in changing and unprecedented economic conditions and predicting developments in public health and fiscal policy related to the pandemic. The ability of our borrowers or counterparties to repay their obligations will likely be impacted by changes in future economic conditions, which in turn could impact the accuracy of our loss forecasts and allowance estimates. There is also the possibility that we have failed or will fail to accurately identify the appropriate economic indicators or accurately estimate their impacts to our borrowers, which similarly could impact the accuracy of our loss forecasts and allowance estimates.
We may suffer unexpected losses if the models and assumptions we use to establish reserves or the judgments we make in extending credit to our borrowers or counterparties, which are more sensitive due to the uncertainty regarding the magnitude and duration of the pandemic and related macroeconomic impact, prove inaccurate in predicting future events. In addition, changes to external factors can negatively impact our recognition of credit losses in our portfolios and allowance for credit losses.
As of January 1, 2020, we implemented a new accounting standard to estimate our allowance for credit losses. Although we believe that the allowance for credit losses is in compliance with the new accounting standard, there is no guarantee that it will be sufficient to address credit losses, particularly if the economic outlook deteriorates significantly. In such an event, we may increase our allowance which would reduce our earnings. Additionally, to the extent that economic conditions worsen as a result of COVID-19 or otherwise, impacting our consumer and commercial borrowers, counterparties or underlying collateral, and credit losses are worse than expected, we may further increase our provision for credit losses, which
could have a further adverse effect on our results of operations and could negatively impact our financial condition.
Our concentrations of credit risk could adversely affect our credit losses, results of operations and financial condition.
In the ordinary course of our business, we may be subject to concentrations of credit risk because of a common characteristic or common sensitivity to economic, financial, public health or business developments. For example, concentrations in credit risk may result in a particular industry, geography, product, asset class, counterparty, individual exposure or within any pool of exposures with a common risk characteristic. A deterioration in the financial condition or prospects of a particular industry, geographic location, product or asset class, or a failure or downgrade of, or default by, any particular entity or group of entities could negatively affect our businesses, and it is possible our limits and credit monitoring exposure controls will not function as anticipated.
While our activities expose us to many different industries and counterparties, we routinely execute a high volume of transactions with counterparties in the financial services industry, including broker-dealers, commercial banks, investment banks, insurers, mutual funds and hedge funds, central counterparties and other institutional clients, resulting in significant credit concentration with respect to this industry. Financial services institutions and other counterparties are inter-related because of trading, funding, clearing or other relationships. As a result, defaults by one or more counterparties, or market uncertainty about the financial stability of one or more financial services institutions, or the financial services industry generally, could lead to market-wide liquidity disruptions, losses and defaults.
Many of these transactions expose us to credit risk and, in some cases, disputes and litigation in the event of default of a counterparty. In addition, our credit risk may be heightened by market risk when the collateral held by us cannot be liquidated or is liquidated at prices not sufficient to recover the full amount of the loan or derivatives exposure due to us, which may occur as a result of fraud or other events that impact the value of the collateral. Further, disputes with obligors as to the valuation of collateral could increase in times of significant market stress, volatility or illiquidity, and we could suffer losses during such periods if we are unable to realize the fair value of the collateral or manage declines in the value of collateral.
Our commercial portfolios include exposures to certain industries, including asset managers and funds, real estate, capital goods and finance companies. Economic weaknesses, adverse business conditions, market disruptions, rising interest or capitalization rates, the collapse of speculative bubbles, greater volatility in areas where we have concentrated credit risk or deterioration in real estate values or household incomes may cause us to experience a decrease in cash flow and higher credit losses in either our consumer or commercial portfolios or cause us to write down the value of certain assets. Additionally, we could experience continued and long-term negative impact to our commercial credit exposure and an increase in credit losses within those industries that continue to be disproportionately impacted by COVID-19 or are permanently impacted by a change in consumer preferences resulting from COVID-19 (including hospitality, entertainment and travel).
Furthermore, we have concentrations of credit risk with respect to our consumer real estate, auto, consumer credit card and commercial real estate portfolios, which represent a significant percentage of our overall credit portfolio. Decreases in home price valuations or commercial real estate valuations in certain markets where we have large concentrations, as well as
11 Bank of America


more broadly within the U.S. or globally, could result in increased defaults, delinquencies or credit loss. In particular, the impact of climate change, such as rising average global temperatures and rising sea levels, and the increasing frequency and severity of extreme weather events and natural disasters such as droughts, floods, wildfires and hurricanes could negatively impact collateral, the valuations of home prices or commercial real estate or our customers’ ability and/or willingness to pay outstanding loans. This could also cause insurability risk and/or increased insurance costs to customers.
We also enter into transactions with sovereign nations, U.S. states and municipalities. Unfavorable economic or political conditions, disruptions to capital markets, currency fluctuations, changes in oil prices, social instability and changes in government or monetary policies could adversely impact the operating budgets or credit ratings of these government entities and expose us to credit risk.
Liquidity disruptions in the financial markets may result in our inability to sell, syndicate or realize the value of our positions, leading to increased concentrations, which could increase the credit and market risk associated with our positions, as well as increase our RWA.
We may be adversely affected if the U.S. housing market weakens or home prices decline.
U.S. home prices continued to generally remain stable or increase in 2020, supported by single-family housing demand and low interest rates. However, changes in business and household behaviors and restrictions on activity in response to the pandemic have had a negative impact on some property markets, particularly in high-density urban areas. We remain conscious of geographic markets where housing price growth has slowed or decreased, or is vulnerable to lasting shifts in demand due to the pandemic, as further declines in future periods may negatively impact the demand for many of our products. Additionally, our mortgage loan production volume is generally influenced by the rate of growth in residential mortgage debt outstanding and the size of the residential mortgage market, both of which may be adversely affected by rising interest rates. Conditions in the U.S. housing market during the 2008 financial crisis resulted in both significant write-downs of asset values in several asset classes, notably mortgage-backed securities, and exposure to monolines. If the U.S. housing market were to weaken, the value of real estate could decline, which could result in increased credit losses and delinquent servicing expenses and negatively affect our representations and warranties exposures, and adversely affect our financial condition and results of operations.
Our derivatives businesses may expose us to unexpected risks and potential losses.
We are party to a large number of derivatives transactions that may expose us to unexpected market, credit and operational risks that could cause us to suffer unexpected losses. Severe declines in asset values, unanticipated credit events or unforeseen circumstances that may cause previously uncorrelated factors to become correlated and vice versa, may create losses resulting from risks not appropriately taken into account or anticipated in the development, structuring or pricing of a derivative instrument. Certain OTC derivative contracts and other trading agreements provide that upon the occurrence of certain specified events, such as a change in the credit rating of the Corporation or one or more of its affiliates, we may be required to provide additional collateral or take other remedial actions and could experience increased difficulty obtaining funding or hedging risks. In some cases our counterparties may have the right to terminate or otherwise diminish our rights under these contracts or agreements.
We are also a member of various central counterparties (CCPs), in part due to regulatory requirements for mandatory clearing of derivative transactions, which potentially increases our credit risk exposures to CCPs. In the event that one or more members of the CCP defaults on its obligations, we may be required to pay a portion of any losses incurred by the CCP as a result of that default. A CCP may modify, in its discretion, the margin we are required to post, which could mean unexpected and increased exposure to the CCP. As a clearing member, we are exposed to the risk of non-performance by our clients for which we clear transactions, which may not be covered by available collateral. Additionally, default by a significant market participant may result in further risk and potential losses.
Geopolitical
We are subject to numerous political, economic, market, reputational, operational, legal, regulatory and other risks in the jurisdictions in which we operate.
We do business throughout the world, including in emerging markets. Economic or geopolitical stress in one or more countries could have a negative impact regionally or globally, resulting in, among other things, market volatility, reduced market value and economic output. Our businesses and revenues derived from non-U.S. jurisdictions are subject to risk of loss from currency fluctuations, financial, social or judicial instability, changes in government leadership, including as a result of electoral outcomes or otherwise, changes in governmental policies or policies of central banks, expropriation, nationalization and/or confiscation of assets, price controls, high inflation, natural disasters, the emergence of widespread health emergencies or pandemics, capital controls, currency redenomination risk, exchange controls, unfavorable political and diplomatic developments, oil price fluctuations and changes in legislation. These risks are especially elevated in emerging markets. Additionally, protectionist trade policies and continued trade tensions between the U.S. and important trading partners, particularly China and the EU, including the risk that tariffs continue to rise and other restrictive actions on cross-border trade, investment, and transfer of information technology are taken that weigh heavily on regional trade volumes and domestic demand through falling business sentiment and lower consumer confidence, could adversely affect our businesses and revenues, as well as our customers and counterparties. Elevated tensions between the U.S. and China also raise the risk that current or future U.S. sanctions against individuals or export controls targeting Chinese firms could prompt retaliatory responses, potentially impacting our operations and revenue.
Additionally, the realization of any significant geopolitical events, negative market conditions and/or change in market dynamics as a result of the U.K.’s exit from the EU could adversely impact our businesses. The short- and long-term impact of the U.K.’s exit from the EU on European and global macroeconomic conditions, our business operations and results of operations remain unknown.
A number of non-U.S. jurisdictions in which we do business have been or may be negatively impacted by slowing growth or recessionary conditions, market volatility and/or political or civil unrest. The ongoing pandemic has had a severe negative impact on global GDP, and the global economic environment remains challenging even as output has begun to improve. Economic weakness may prove persistent in many countries and regions, including Europe, Japan, and numerous emerging markets. Potential risks of default on or devaluation of sovereign debt in some non-U.S. jurisdictions could expose us to substantial losses. As a result of the pandemic and fiscal policy responses
Bank of America 12


to it, government debt levels have increased significantly, raising the risk of volatility, significant valuation changes, or default in markets for sovereign debt. Risks in one nation can limit our opportunities for portfolio growth and negatively affect our operations in other nations, including our U.S. operations. Market and economic disruptions of all types may affect consumer confidence levels and spending, corporate investment and job creation, bankruptcy rates, levels of incurrence and default on consumer and corporate debt, economic growth rates and asset values, among other factors. Any such unfavorable conditions or developments could adversely impact us.
We also invest or trade in the securities of corporations and governments located in non-U.S. jurisdictions, including emerging markets. Revenues from the trading of non-U.S. securities may be subject to negative fluctuations as a result of the above factors. Furthermore, the impact of these fluctuations could be magnified because non-U.S. trading markets, particularly in emerging markets, are generally smaller, less liquid and more volatile than U.S. trading markets.
Our non-U.S. businesses are also subject to extensive regulation by governments, securities exchanges and regulators, central banks and other regulatory bodies. In many countries, the laws and regulations applicable to the financial services and securities industries are uncertain and evolving, and it may be difficult for us to determine the exact requirements of local laws in every market or manage our relationships with multiple regulators in various jurisdictions. Our potential inability to remain in compliance with local laws in a particular market and manage our relationships with regulators could result in increased expenses and changes to our organizational structure and adversely affect our businesses and results of operations in that market, as well as our reputation in general.
In connection with the U.K.’s exit from the EU, we are now subject to different laws, regulations and regulatory authorities and increased organizational and operational complexity. We may incur additional costs and/or experience negative tax consequences as a result of operating our principal EU banking and broker-dealer operations outside of the U.K., which could adversely impact our EU business, results of operations and operational model. Further, changes to the legal and regulatory framework under which our subsidiaries provide products and services in the U.K. and in the EU may result in additional compliance costs and have negative tax consequences or an adverse impact on our results of operations.
In addition to non-U.S. legislation, our international operations are also subject to U.S. legal requirements, which subjects us to operational and compliance costs and risks. For example, our operations are subject to U.S. and non-U.S. laws and regulations relating to bribery and corruption, anti-money laundering, and economic sanctions, which can vary by jurisdiction. The increasing speed and novel ways in which funds circulate could make it more challenging to track the movement of funds and heightens financial crimes risk. Our ability to comply with these legal requirements depends on our ability to continually improve surveillance, detection and reporting and analytic capabilities.
In the U.S., debt ceiling and budget deficit concerns, which have increased the possibility of U.S. government defaults on its debt and/or downgrades to its credit ratings, and prolonged government shutdowns could negatively impact the global economy and banking system and adversely affect our financial condition, including our liquidity. Additionally, changes in fiscal, monetary or regulatory policy, including as a result of the change in the U.S. presidential administration and Congress, could increase our compliance costs and adversely affect our
business operations, organizational structure and results of operations. We are also subject to geopolitical risks, including economic sanctions, acts or threats of international or domestic terrorism, actions taken by the U.S. or other governments in response thereto, state-sponsored cyber attacks or campaigns, civil unrest and/or military conflicts, which could adversely affect business and economic conditions abroad and in the U.S.
Business Operations
A failure in or breach of our operational or security systems or infrastructure or business continuity plans, or those of third parties or the financial services industry, could disrupt our critical business operations and customer services, result in regulatory, market, privacy, liquidity and operational risk exposures, and adversely impact our results of operations and financial condition, and cause legal or reputational harm.
The potential for operational risk exposure exists throughout our organization and as a result of our interactions with, and reliance on, third parties (including their downstream service providers) and the financial services industry infrastructure. Our operational and security systems infrastructure, including our computer systems, emerging technologies, data management and internal processes, as well as those of third parties, are integral to our performance. We also rely on our employees and third parties (including downstream service providers) in our day-to-day and ongoing operations, who may, as a result of human error, misconduct (including fraudulent activity), malfeasance or a failure or breach of systems or infrastructure cause disruptions to our organization and expose us to operational and regulatory risk.
Additionally, our financial, accounting, data processing and transmission, storage, backup or other operating or security systems and infrastructure, or those of third parties with whom we interact or upon whom we rely may fail to operate properly or become disabled or damaged as a result of a number of factors including events that are wholly or partially beyond our or such third party’s control, which could adversely affect our ability to process transactions or provide services. We could also experience prolonged computer and network outages resulting in disruptions to our critical business operations and customer services, including abuse or failure of our electronic trading and algorithmic platforms. We may experience sudden increases in customer transaction volume or electrical, telecommunications or other major physical infrastructure outages, newly identified vulnerabilities in key hardware or software, failure of aging infrastructure and technology project implementation challenges, which could result in prolonged operational outages. Climate change is increasing the frequency and severity of natural disasters, such as earthquakes, wildfires, tornadoes, hurricanes and floods, which could result in increased exposure to operational risks, including outages. Additionally, events arising from local or larger scale political or social matters, including civil unrest and terrorist acts, could result in operational disruptions and prolonged operational outages.
Additionally, the Corporation and the third parties on which it relies have been and will likely continue to be subject to additional operational risks while operating in a work-from-home posture (which places greater reliance on remote access tools and technology and employees’ personal systems), while executing business continuity plans due to COVID-19. We are increasingly dependent upon our information technology infrastructure to operate our businesses remotely due to our work-from-home posture and evolving customer preferences, including increased reliance on digital banking and other digital
13 Bank of America


services provided by our businesses. Effective management of our work-from-home posture depends on the security, reliability and adequacy of such systems. We are also at greater risk of business disruptions due to illness and unavailability.
Regardless of the measures we have taken to implement training, procedures, backup systems and other safeguards to support our operations and bolster our operational resilience, our ability to conduct business may be adversely affected by any significant disruptions to us or to third parties (including their downstream service providers) with whom we interact or upon whom we rely, including systemic cyber events that result in system outages and unavailability of part or all of the financial services industry infrastructure. Our ability to implement backup systems and other safeguards with respect to third-party systems and the financial services industry infrastructure is more limited than with respect to our own systems.
Furthermore, to the extent that backup systems are available and utilized, they may not process data as quickly as our primary systems and some data might not have been backed up. We regularly update the systems on which we rely to support our operations and growth and to remain compliant with all applicable laws, rules and regulations globally. This updating entails significant costs and creates risks associated with implementing new systems and integrating them with existing ones, including business interruptions. A failure or breach of our operational or security systems or infrastructure or business continuity plans resulting in disruption to our critical business operations and customer services could expose us to regulatory, market, privacy and liquidity risk, and adversely impact our results of operations and financial condition, as well as cause legal or reputational harm.
A cyber attack, information or security breach, or a technology failure of ours or of a third party could adversely affect our ability to conduct our business, manage our exposure to risk or expand our businesses, result in the disclosure or misuse of confidential or proprietary information, and/or fraudulent activity, and increase our costs to maintain and update our operational and security systems and infrastructure.
Our business is highly dependent on the security, controls and efficacy of our infrastructure, computer and data management systems, as well as those of our customers, suppliers, counterparties and other third parties (including their downstream service providers) the financial services industry and financial data aggregators, with whom we interact, on whom we rely or who have access to our customers' personal or account information. Our business relies on effective access management and the secure collection, processing, transmission, storage and retrieval of confidential, proprietary, personal and other information in our computer and data management systems and networks, and in the computer and data management systems and networks of third parties. In addition, to access our network, products and services, our employees, customers, suppliers, counterparties and other third parties increasingly use personal mobile devices or computing devices that are outside of our network and control environments and are subject to their own cybersecurity risks.
We, our employees and customers, regulators and other third parties (including contractors and vendors) are regularly the target of cyber attacks and are likely to continue to be the target of cyber attacks. These cyber attacks are pervasive, sophisticated, evolving, difficult to prevent and include computer viruses, malicious or destructive code (such as ransomware), social engineering (including phishing, vishing and smithing), denial of service or information or other security breach tactics that could result in the unauthorized release, gathering,
monitoring, misuse, loss or destruction or theft of confidential, proprietary and other information, including intellectual property, of ours, our employees, our customers or of third parties. These cyber attacks could also result in damages to systems, financial risk or otherwise material disruption to our or our customers’ or other third parties’ network access or business operations, both domestically and internationally.
Our cybersecurity risk and exposure remains heightened because of, among other things, the evolving nature and pervasiveness of cyber threats, our prominent size and scale, our geographic footprint and international presence and our role in the financial services industry and the broader economy. Additionally, our risk and exposure to cyber attacks and security breaches is magnified due to our work-from-home posture which places greater reliance on remote access tools and technology, resulting in a larger number of access points to our networks that must be secured. This increased risk of unauthorized access to our networks results in greater amounts of information being available for access from employees’ personal devices over which we do not have the same controls as we do in a non-work-from-home posture. Additionally, our customers’ increasing reliance on digital banking and other digital services provided by our businesses in response to COVID-19, has resulted in more demand on our information technology infrastructure and security tools and processes.
The financial services industry is particularly at risk because of the proliferation of new and emerging technologies, including third-party financial data aggregators, and the use of the internet and telecommunications technologies to conduct financial transactions. Additionally, our use of automation, artificial intelligence (AI) and robotics, increased use of internet and mobile banking products, including mobile payment and other web- and cloud-based products and applications and plans to use or develop additional remote connectivity solutions increase our cybersecurity risks and exposure.
Additionally, we have exposure to cyber threats as a result of our continuous transmission of sensitive information to, and storage of such information by, third parties, including our vendors and regulators, the outsourcing of some of our business operations, and system and customer account updates and conversions. Cybersecurity risks have also significantly increased in recent years in part due to the increasingly sophisticated activities of organized crime groups, hackers, terrorist organizations, extremist parties, hostile foreign governments and state-sponsored actors, in some instances acting to promote political ends. We could also be the target of disgruntled employees or vendors, activists and other parties, including those involved in corporate espionage.
Cyber threats and the techniques used in cyber attacks change rapidly and frequently. Despite substantial efforts to protect the integrity and resilience of our systems and implement controls, processes, policies and other protective measures, we may not be able to anticipate cyber attacks or information or security breaches and implement effective preventive or defensive measures to address or mitigate such attacks or breaches. Even the most advanced internal control environment is vulnerable to compromise. Internal access management failures could result in the compromise or unauthorized exposure of confidential data.
Cyber attacks or security breaches could persist for an extended period of time before being detected. It could take considerable additional time for us to determine the scope, extent, amount, and type of information compromised, at which time the impact on the Corporation and measures to recover and restore to a business-as-usual state may be difficult to
Bank of America 14


assess. As cyber threats continue to evolve, we may be required to expend significant additional resources to modify or enhance our protective measures, investigate and remediate any information security vulnerabilities or incidents and develop our capabilities to respond and recover. As a result, increasing resources to develop and enhance our controls, processes and practices designed to protect our systems, workstations, intellectual property and proprietary information, software, data and networks from attack, damage or unauthorized access, remains a critical priority.
We also face indirect technology, cybersecurity and operational risks relating to the customers, clients and other third parties (including their downstream service providers) and the financial services industry, with whom we do business, upon whom we rely to facilitate or enable our business activities or upon whom our customers rely. Such third parties also include financial counterparties, financial data aggregators, financial intermediaries, such as clearing agents, exchanges and clearing houses, vendors, regulators, providers of critical infrastructure, such as internet access and electrical power, and retailers for whom we process transactions. As a result of increasing consolidation, interdependence and complexity of financial entities and technology systems, a technology failure, cyber attack or other information or security breach that significantly degrades, deletes or compromises the systems or data of one or more financial entities or third parties (or their downstream service providers) could have a material impact on counterparties or other market participants, including us. Similarly, any failure, cyber attack or other information or security breach that significantly degrades, deletes or compromises our systems or data could adversely impact third parties, counterparties and the financial services industry infrastructure, which in turn could harm our reputation and damage our business. This consolidation, interconnectivity and complexity increases the risk of operational failure, on both individual and industry-wide bases, as disparate systems need to be integrated, often on an accelerated basis. Any technology failure, cyber attack or other information or security breach, termination or constraint of any third party (including their downstream service providers) the financial services industry infrastructure or financial data aggregators, could, among other things, adversely affect our ability to conduct day-to-day business activities, effect transactions, service our clients, manage our exposure to risk or expand our businesses, result in the misappropriation or destruction of the personal, proprietary or confidential information of our employees, customers, suppliers, counterparties and other third parties or result in fraudulent or unauthorized transactions. Further, any such event may not be disclosed to us in a timely manner.
Although to date we have not experienced any material losses or other material consequences relating to technology failure, cyber attacks or other information or security breaches, whether directed at us or third parties, there can be no assurance that our controls and procedures in place to monitor and mitigate the risks of cyber threats will be sufficient and that we will not suffer material losses or consequences in the future. Cyber attacks or other information or security breaches, whether directed at us or third parties, may result in significant lost revenue, give rise to losses and claims brought by third parties, government penalties and other negative consequences. Furthermore, the public perception that a cyber attack on our systems has been successful, whether or not this perception is correct, may damage our reputation with customers and third parties with whom we do business. Although we maintain cyber insurance, there can be no assurance that liabilities or losses
we may incur will be covered under such policies or that the amount of insurance will be adequate.
Also, successful penetration or circumvention of system security could result in negative consequences, including loss of customers and business opportunities, the withdrawal of customer deposits, prolonged computer and network outages resulting in disruptions to our critical business operations and customer services, misappropriation or destruction of our intellectual property, proprietary information or confidential information and/or the confidential, proprietary or personal information of certain parties, such as our employees, customers, suppliers, counterparties and other third parties, or damage to their computers or systems. This could result in a violation of applicable privacy and other laws in the U.S. and abroad, litigation exposure, regulatory fines, penalties or intervention, loss of confidence in our security measures, reputational damage, reimbursement or other compensatory costs, additional compliance costs, and our internal controls or disclosure controls being rendered ineffective. The occurrence of any of these events could adversely impact our results of operations, liquidity and financial condition.
Failure to satisfy our obligations as servicer for residential mortgage securitizations, loans owned by other entities and other losses we could incur as servicer, could adversely impact our reputation, servicing costs or results of operations.
We and our legacy companies service mortgage loans on behalf of third-party securitization vehicles and other investors. If we commit a material breach of our obligations as servicer or master servicer, we may be subject to termination if the breach is not cured within a specified period of time following notice, which could cause us to lose servicing income. In addition, we may have liability for any failure by us, as a servicer or master servicer, for any act or omission on our part that involves willful misfeasance, bad faith, gross negligence or reckless disregard of our duties. If any such breach was found to have occurred, it may harm our reputation, increase our servicing costs, result in litigation or regulatory action or adversely impact our results of operations. Additionally, with respect to foreclosures, we may incur costs or losses due to irregularities in the underlying documentation, or if the validity of a foreclosure action is challenged by a borrower or overturned by a court because of errors or deficiencies in the foreclosure process. We may also incur costs or losses relating to delays or alleged deficiencies in processing documents necessary to comply with state law governing foreclosure.
Changes in the structure of and relationship among the GSEs could adversely impact our business.
During 2020, we sold approximately $3.6 billion of loans to GSEs, primarily Freddie Mac (FHLMC). FHLMC and Fannie Mae (FNMA) are currently in conservatorship with their primary regulator, the Federal Housing Finance Agency (FHFA) acting as conservator. In September 2019, the Treasury Department published a proposal to recapitalize FHLMC and FNMA and remove them from conservatorship as well as reduce their role in the marketplace. Consistent with this proposal, in January 2021, the Treasury Department further amended the agreement that governs the conservatorship of FHLMC and FNMA to allow them to retain their earnings until they reach certain previously determined capital requirements, among other policy actions, potentially putting them on a long-term path to emergence from conservatorship. However, we cannot predict the future prospects of the GSEs, timing of the recapitalization or release from conservatorship, or content of legislative or rulemaking proposals regarding the future status of the GSEs in the housing market. Additionally, if the GSEs were to take a reduced role in
15 Bank of America


the marketplace, including by limiting the mortgage products they offer, we could be required to seek alternative funding sources, retain additional loans on our balance sheet, secure funding through the Federal Home Loan Bank system, or securitize the loans through Private Label Securitization. Accordingly, uncertainty regarding their future and the mortgage-backed securities they guarantee continues to exist for the foreseeable future.
Any of these developments could adversely affect the value of our securities portfolios, capital levels, liquidity and results of operations.
Our risk management framework may not be effective in mitigating risk and reducing the potential for losses.
Our risk management framework is designed to minimize risk and loss to us. We seek to effectively and consistently identify, measure, monitor, report and control the types of risk to which we are subject, including strategic, credit, market, liquidity, compliance, operational and reputational risks. While we employ a broad and diversified set of controls and risk mitigation techniques, including modeling and forecasting, hedging strategies and techniques that seek to balance our ability to profit from trading positions with our exposure to potential losses, our ability to control and mitigate risks that result in losses is inherently limited by our ability to identify all risks, including emerging and unknown risks, anticipate the timing of risks, apply effective hedging strategies, make correct assumptions, manage and aggregate data correctly and efficiently, and develop risk management models to assess and control risk.
Our ability to manage risk is dependent on our ability to consistently execute all elements of our risk management program and develop and maintain a culture of managing risk well throughout the Corporation and manage risks associated with third parties (including their downstream service providers) and vendors, to enable effective risk management and ensure that risks are appropriately considered, evaluated and responded to in a timely manner. Uncertain economic conditions, heightened legislative and regulatory scrutiny of and change within the financial services industry, the pace of technological changes, accounting and market developments, the failure of employees to comply with policies, values and our risk framework and the overall complexity of our operations, among other developments, may result in a heightened level of risk for us. We have experienced increased operational, reputational and compliance risk as a result of the need to rapidly implement multiple and varying pandemic relief programs, including consumer and commercial assistance programs and the PPP, coupled with the concurrent transition of the Corporation’s workforce to a work-from-home posture. Accordingly, we could suffer losses as a result of our failure to manage evolving risks or properly anticipate, manage, control or mitigate risks.
Regulatory, Compliance and Legal
We are subject to comprehensive government legislation and regulations and certain settlements, orders and agreements with government authorities from time to time.
We are subject to comprehensive regulation under federal and state laws in the U.S. and the laws of the various jurisdictions in which we operate, including increasing and complex economic sanctions regimes. These laws and regulations significantly affect and have the potential to restrict the scope of our existing businesses, limit our ability to pursue certain business opportunities, including the products and
services we offer, reduce certain fees and rates or make our products and services more expensive for our clients.
We continue to make adjustments to our business and operations, legal entity structure and capital and liquidity management policies, procedures and controls to comply with currently effective laws and regulations, as well as final rulemaking, guidance and interpretation by regulatory authorities, including the Department of Treasury, Federal Reserve, OCC, CFPB, Financial Stability Oversight Council, FDIC, Department of Labor, SEC and CFTC in the U.S. and foreign regulators and other government authorities. Further, we could become subject to future legislation and regulatory requirements beyond those currently proposed, adopted or contemplated in the U.S. or abroad, including policies and rulemaking related to the Financial Reform Act, the pandemic and climate change. The cumulative effect of all of the legislation and regulations on our business, operations and profitability remains uncertain. This uncertainty necessitates that in our business planning we make certain assumptions with respect to the scope and requirements of prospective and proposed rules. If these assumptions prove incorrect, we could be subject to increased regulatory and compliance risks and costs as well as potential reputational harm. In addition, U.S. and international regulatory initiatives may overlap, and non-U.S. regulations and initiatives may be inconsistent or may conflict with current or proposed U.S. regulations, which could lead to compliance risks and increased costs.
Our regulators’ prudential and supervisory authority gives them broad power and discretion to direct our actions, and they have assumed an active oversight, inspection and investigatory role across the financial services industry. However, regulatory focus is not limited to laws and regulations applicable to the financial services industry, but extends to other significant laws and regulations that apply across industries and jurisdictions, including those related to data management and privacy, anti-money laundering, anti-corruption and economic sanctions.
We are also subject to laws, rules and regulations in the U.S. and abroad, including GDPR, CCPA and CPRA, regarding compliance with our privacy policies and the disclosure, collection, use, sharing and safeguarding of personal identifiable information of certain parties, such as our employees, customers, suppliers, counterparties and other third parties, the violation of which could result in litigation, regulatory fines and enforcement actions. Additionally, we will likely be subject to new and evolving data privacy laws in the U.S. and abroad, which could result in additional costs of compliance, litigation, regulatory fines and enforcement actions. In particular, there is increased complexity and uncertainty, including potential suspension or prohibition, regarding the standards used by the Corporation for cross-border flows and transfers of personal data from the European Economic Area (EEA) to the U.S. and other jurisdictions outside of the EEA resulting from a decision of the Court of Justice of the EU and guidance from the European Data Protection Board. Additionally, the European Commission has proposed new standards of personal data transfer. If our personal data transfers are suspended or prohibited or we are required to implement new standards, this could result in operational disruptions to our businesses, additional costs, increased enforcement activity, new contract negotiations with third parties, and/or modification of our cross-border data management.
As part of their enforcement authority, our regulators and other government authorities have the authority to, among other things, assess significant civil or criminal monetary penalties or restitution and issue cease and desist or removal orders and
Bank of America 16


initiate injunctive actions. The amounts paid by us and other financial institutions to settle proceedings or investigations have, in some instances, been substantial and may increase. In some cases, governmental authorities have required criminal pleas or other extraordinary terms as part of such resolutions, which could have significant consequences, including reputational harm, loss of customers, restrictions on the ability to access capital markets, and the inability to operate certain businesses or offer certain products for a period of time.
The Corporation and the conduct of its employees and representatives are subject to regulatory scrutiny across jurisdictions. The complexity of the federal and state regulatory and enforcement regimes in the U.S., coupled with the global scope of our operations and the regulatory environment worldwide also means that a single event or practice or a series of related events or practices may give rise to a significant number of overlapping investigations and regulatory proceedings, either by multiple federal and state agencies in the U.S. or by multiple regulators and other governmental entities in different jurisdictions. Additionally, actions by other members of the financial services industry related to business activities in which we participate may result in investigations by regulators or other government authorities. Responding to inquiries, investigations, lawsuits and proceedings is time-consuming and expensive and can divert senior management attention from our business. The outcome of such proceedings, which may last a number of years, may be difficult to predict or estimate.
We are and may become subject to the terms of settlements, orders and agreements that we have entered into with government entities and regulatory authorities, which impose, or could impose, significant operational and compliance costs on us as they typically require us to enhance our procedures and controls, expand our risk and control functions within our lines of business, invest in technology and hire significant numbers of additional risk, control and compliance personnel. Moreover, if we fail to meet the requirements of the regulatory settlements, orders or agreements to which we are subject, or, more generally, fail to maintain risk and control procedures and processes that meet the heightened standards established by our regulators and other government authorities, we could be required to enter into further settlements, orders or agreements and pay additional fines, penalties or judgments, or accept material regulatory restrictions on our businesses.
While we believe that we have adopted appropriate risk management and compliance programs to identify, assess, monitor and report on applicable laws, policies and procedures, compliance risks will continue to exist, particularly as we adapt to new and evolving laws, rules and regulations. Additionally, changing U.S. fiscal, monetary and regulatory policies arising from changes to the U.S. presidential administration and Congress result in ongoing regulatory uncertainties. There is no guarantee that our risk management and compliance programs will be consistently executed to successfully manage compliance risk. We also rely upon third parties who may expose us to compliance and legal risk. Future legislative or regulatory actions, and any required changes to our business or operations, or those of third parties (including their downstream providers) upon whom we rely, resulting from such developments and actions could result in a significant loss of revenue, impose additional compliance and other costs or otherwise reduce our profitability, limit the products and services that we offer or our ability to pursue certain business opportunities, require us to dispose of or curtail certain businesses, affect the value of assets that we hold, require us to increase our prices and therefore reduce demand for our
products, or otherwise adversely affect our businesses. In addition, legal and regulatory proceedings and other contingencies will arise from time to time that may result in fines, regulatory sanctions, penalties, equitable relief and changes to our business practices. As a result, we are and will continue to be subject to heightened compliance and operating costs that could adversely affect our results of operations.
We are subject to significant financial and reputational risks from potential liability arising from lawsuits and regulatory and government action.
We continue to face significant legal risks in our business, with a high volume of claims against us and other financial institutions. The damages, penalties and fines that litigants and regulators seek from us and other financial institutions continue to be high. This includes disputes with consumers, customers and other counterparties.
Financial institutions, including us, continue to be the subject of claims alleging anti-competitive conduct with respect to various products and markets, including U.S. antitrust class actions claiming joint and several liability for treble damages. As disclosed in Note 12 — Commitments and Contingencies to the Consolidated Financial Statements, we also face contractual indemnification and loan-repurchase claims arising from alleged breaches of representations and warranties in the sale of residential mortgages by legacy companies, which may result in a requirement that we repurchase the mortgage loans, or otherwise make whole or provide other remedies to counterparties.
In addition, regulatory authorities have had a supervisory focus on enforcement, including in connection with alleged violations of law and customer harm. For example, U.S. regulators and government agencies have pursued claims against financial institutions under the Financial Institutions Reform, Recovery, and Enforcement Act, False Claims Act, Equal Credit Opportunity Act, Fair Housing Act and antitrust laws. Such claims may carry significant and, in certain cases, treble damages. There is also an increased focus on compliance with global laws, rules and regulations related to the collection, use, sharing and safeguarding of personally identifiable information and corporate data. Additionally, misconduct by employees, including unethical, fraudulent, improper or illegal conduct, or other unfair, deceptive, abusive or discriminatory business practices, can result in litigation and/or government investigations and enforcement actions, and cause significant reputational harm.
The global environment of extensive regulation, regulatory compliance burdens, litigation and regulatory enforcement, combined with uncertainty related to the continually evolving regulatory environment, may affect operational and compliance costs and risks, which may limit or cease our ability to continue providing certain products and services. This is magnified by the Corporation's implementation of government relief measures related to the pandemic. Lawsuits and regulatory actions may result in judgments, settlements, penalties and fines adverse to the Corporation. Litigation and investigation costs, substantial legal liability or significant regulatory or government action against us could have adverse effects on our business, financial condition, including liquidity, and results of operations, and/or cause significant reputational harm to us.
U.S. federal banking agencies may require us to increase our regulatory capital, total loss-absorbing capacity (TLAC), long-term debt or liquidity requirements.
We are subject to U.S. regulatory capital and liquidity rules. These rules, among other things, establish minimum requirements to qualify as a well-capitalized institution. If any of
17 Bank of America


our subsidiary insured depository institutions fails to maintain its status as well capitalized under the applicable regulatory capital rules, the Federal Reserve will require us to agree to bring the insured depository institution back to well-capitalized status. For the duration of such an agreement, the Federal Reserve may impose restrictions on our activities. If we were to fail to enter into or comply with such an agreement, or fail to comply with the terms of such agreement, the Federal Reserve may impose more severe restrictions on our activities, including requiring us to cease and desist activities permitted under the Bank Holding Company Act of 1956.
Capital and liquidity requirements are frequently introduced and amended. It is possible that regulators may increase regulatory capital requirements including TLAC and long-term debt requirements, change how regulatory capital is calculated or increase liquidity requirements. Our ability to return capital to our shareholders depends in part on our ability to maintain regulatory capital levels above minimum requirements plus buffers. To the extent that increases occur in our SCB, G-SIB surcharge or countercyclical capital buffer, our returns of capital to shareholders could decrease.
As part of its CCAR, the Federal Reserve conducts stress testing on parts of our business using hypothetical economic scenarios prepared by the Federal Reserve. Those scenarios may affect our CCAR stress test results, which may impact the level of our SCB. Additionally, the Federal Reserve may impose limitations or prohibitions on taking capital actions, such as paying or increasing dividends or repurchasing common stock. For example, as a result of the economic uncertainty resulting from the pandemic, the Federal Reserve applied certain restrictions on our common stock dividends and repurchase program during the second half of 2020, and the first quarter of 2021, as disclosed in Item 1. Business Distributions on page 5 and MD&A Executive Summary Recent Developments Capital Management on page 25.
A significant component of regulatory capital ratios is calculating our RWA and our leverage exposure, which may increase. The Basel Committee on Banking Supervision has also revised several key methodologies for measuring RWA that have not yet been implemented in the U.S., including a standardized approach for operational risk, revised market risk requirements and constraints on the use of internal models, as well as a capital floor based on the revised standardized approaches. U.S. banking regulators may update the U.S. Basel 3 rules to incorporate the Basel Committee revisions.
Changes to and compliance with the regulatory capital and liquidity requirements may impact our operations by requiring us to liquidate assets, increase borrowings, issue additional equity or other securities, cease or alter certain operations or hold highly liquid assets, which may adversely affect our results of operations.
Changes in accounting standards or assumptions in applying accounting policies could adversely affect us.
Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Some of these policies require use of estimates and assumptions that may affect the reported value of our assets or liabilities and results of operations and are critical because they require management to make difficult, subjective and complex judgments about matters that are inherently uncertain. If those assumptions, estimates or judgments were incorrectly made, we could be required to correct and restate prior-period financial statements. Accounting standard-setters and those who interpret the accounting standards, the SEC, banking regulators and our independent registered public accounting firm may also
amend or even reverse their previous interpretations or positions on how various standards should be applied. These changes may be difficult to predict and could impact how we prepare and report our financial statements. In some cases, we could be required to apply a new or revised standard retrospectively, resulting in us revising prior-period financial statements.
We may be adversely affected by changes in U.S. and non-U.S. tax laws and regulations.
In December 2017, the Tax Cuts and Jobs Act (the Tax Act) was enacted, which made significant changes to federal income tax law including, among other things, reducing the statutory corporate income tax rate to 21 percent from 35 percent and changing the taxation of our non-U.S. business activities.
In addition, we have U.K. net deferred tax assets (DTA) which consist primarily of net operating losses that are expected to be realized by certain subsidiaries over an extended number of years. Adverse developments with respect to tax laws or to other material factors, such as prolonged worsening of Europe’s capital markets or changes in the ability of our U.K. subsidiaries to conduct business in the EU, could lead our management to reassess and/or change its current conclusion that no valuation allowance is necessary with respect to our U.K. net DTA.
It is possible that governmental authorities in the U.S. and/or other countries could further amend or repeal tax laws in a way that would adversely affect us, including the possibility that aspects of the Tax Act could be amended in the future. Any future change in tax laws and regulations or interpretations of current or future tax laws and regulations could adversely affect our results of operations.
Reputation
Damage to our reputation could harm our businesses, including our competitive position and business prospects.
Our ability to attract and retain customers, clients, investors and employees is impacted by our reputation. Harm to our reputation can arise from various sources, including officer, director or employee fraud, misconduct and unethical behavior, security breaches, litigation or regulatory outcomes, compensation practices, lending practices, the suitability or reasonableness of recommending particular trading or investment strategies, including the reliability of our research and models, prohibiting clients from engaging in certain transactions and employee sales practices. Additionally, our reputation may be harmed by failing to deliver products, subpar standards of service and quality expected by our customers, clients and the community, compliance failures, the inability to manage technology change or maintain effective data management, cyber incidents, internal and external fraud, inadequacy of responsiveness to internal controls, unintended disclosure of personal, proprietary or confidential information, conflicts of interest and breach of fiduciary obligations, the handling of health emergencies or pandemics, and the activities of our clients, customers, counterparties and third parties, including vendors. For example, our reputation may be harmed in connection with our implementation of government programs to provide relief to address the economic impact of the pandemic. Our reputation may also be negatively impacted by our ESG practices and disclosures, our businesses and our customers, including practices and disclosures related to climate change. Actions by the financial services industry generally or by certain members or individuals in the industry also can adversely affect our reputation. In addition, adverse publicity or negative information posted on social media by employees, the media or otherwise, whether or not factually
Bank of America 18


correct, may adversely impact our business prospects or financial results.
We are subject to complex and evolving laws and regulations regarding privacy, know-your-customer requirements, data protection, including the GDPR, CCPA and CPRA, cross-border data movement and other matters. Principles concerning the appropriate scope of consumer and commercial privacy vary considerably in different jurisdictions, and regulatory and public expectations regarding the definition and scope of consumer and commercial privacy may remain fluid. It is possible that these laws may be interpreted and applied by various jurisdictions in a manner inconsistent with our current or future practices, or that is inconsistent with one another. If personal, confidential or proprietary information of customers or clients in our possession, or in the possession of third parties (including their downstream service providers) or financial data aggregators, is mishandled, misused or mismanaged, or if we do not timely or adequately address such information, we may face regulatory, reputational and operational risks which could adversely affect our financial condition and results of operations.
We could suffer reputational harm if we fail to properly identify and manage potential conflicts of interest. Management of potential conflicts of interest has become increasingly complex as we expand our business activities through more numerous transactions, obligations and interests with and among our clients. The failure to adequately address, or the perceived failure to adequately address, conflicts of interest could affect the willingness of clients to use our products and services, or give rise to litigation or enforcement actions, which could adversely affect our business.
Our actual or perceived failure to address these and other issues, such as operational risks, gives rise to reputational risk that could harm us and our business prospects. Failure to appropriately address any of these issues could also give rise to additional regulatory restrictions, legal risks and reputational harm, which could, among other consequences, increase the size and number of litigation claims and damages asserted or subject us to enforcement actions, fines and penalties, and cause us to incur related costs and expenses.
Other
Reforms to and replacement of IBORs and certain other rates or indices may adversely affect our reputation, business, financial condition and results of operations.
There is a major transition in progress in global financial markets with respect to the replacement of IBORs, including the London Interbank Offered Rate (LIBOR), and certain other rates or indices that serve as “benchmarks.” Such benchmarks are used extensively across global financial markets and in our business. In particular, LIBOR is used in many of our products and contracts, including derivatives, consumer and commercial loans, mortgages, floating-rate notes and other adjustable-rate products and financial instruments. The aggregate notional amount of these products and contracts is material to our business, and there are significant risks and challenges associated with the transition that may result in significant uncertainty, or have other consequences that cannot be fully anticipated, which expose us to various financial, operational, supervisory, conduct and legal risks.
Although certain ARRs have been proposed to replace LIBOR and other IBORs, market and client adoption of ARRs may vary across or within categories of contracts, products and services, resulting in market fragmentation, decreased trading volumes and liquidity, increased complexity and modeling and
operational risks. ARRs have compositions and characteristics that differ significantly from the benchmarks they may replace, in some cases have limited history, and may demonstrate less predictable performance over time than the benchmarks they replace. Additionally, most ARRs are calculated on a compounded or weighted-average basis, involve complex billing and reconciliation and, unlike IBORs, do not reflect bank credit risk and therefore may require a spread adjustment. The market transition from IBORs to ARRs is complex and there are important differences between the fallbacks, triggers and calculation methodologies being implemented in cash and derivatives markets (including within cash markets). Any mismatch between the adoption of ARRs in loans, securities and derivatives markets may impact hedging or other financial arrangements we have implemented, and as a result we may experience unanticipated market exposures. There can be no assurance that ARRs will be comparable or adequate alternatives to IBORs or perform in the same way, that existing assets and liabilities based on or linked to IBORs will transition successfully to ARRs, of the timing of adoption and degree of integration and acceptance of ARRs in the financial markets, or of the future availability or representativeness of such ARRs.
The discontinuation of IBORs, including LIBOR, requires us to transition a significant number of IBOR-based products and contracts, including related hedging arrangements (IBOR Products). Although, a significant majority of the aggregate notional amount of our LIBOR-based products and contracts maturing after 2021 include or have been updated to include fallbacks to ARRs, the transitioning of certain contracts, products and clients will be more complex. While some of these outstanding IBOR Products include fallback provisions to ARRs, some of these products and contracts do not include fallback provisions or adequate fallback mechanisms and require remediation to modify their terms. Additionally, some outstanding IBOR Products are particularly challenging to modify due to the requirement that all impacted parties consent to such modification. Legislation has been adopted in the EU and proposed in the U.S. and the U.K. to address such challenges in IBOR Products, including the use of a statutory replacement or “synthetic” rate to replace the existing benchmark rate in certain of our IBOR Products. Litigation, disputes or other action may occur as a result of the interpretation or application of legislation, in particular, if there is an overlap between legislation introduced in different jurisdictions. There is no guarantee that the legislative proposals will become law and no assurance that we and other market participants will be able to successfully modify all outstanding IBOR Products or be adequately prepared for a discontinuation of an IBOR at the time such IBOR may cease to be published or otherwise discontinued. Also, there can be no assurance that existing or new provisions for successor rates in our IBOR Products will include adequate methodologies for adjustments or that the characteristics of the successor rates will be similar to or produce the economic equivalent of the benchmarks they seek to replace. These changes may adversely affect the yield on loans or securities held by us, amounts paid on securities we have issued, amounts received and paid on derivatives we have entered into, the value of such loans, securities or derivative instruments, the trading market for such products and contracts, and our ability to effectively use hedging instruments to manage risk. Certain impacted clients, counterparties and other market participants may refuse, delay, or lack operational readiness to transition to ARRs, resulting in the risk that some contracts and products may not transition to an ARR before discontinuation of the relevant IBOR, exposing us to financial, operational, supervisory, conduct and legal risks.
19 Bank of America


Our products and contracts that reference IBORs, in particular LIBOR, may contain language that determines when a successor rate including the ARR and/or the applicable spread adjustment to the designated rate (including IBORs) would be selected or determined. If a trigger is satisfied, our products and contracts may give the calculation agent (which may be us) discretion over the successor rate to be selected. We may face a risk of litigation, disputes or other actions from clients, counterparties, customers, investors or others regarding the interpretation or enforcement of IBOR-based contract provisions or if we fail to appropriately communicate the effect that the transition to ARRs will have on existing and future products.
The Corporation has launched, and expects to continue to develop, launch and support, ARR-based products and services. The transition to ARR-based products is complex and involves client and financial contract changes, internal and external communication, technology and operations modifications, industry and regulatory engagement, migration of existing clients, execution of business strategy and governance. New financial products linked to ARRs may be less liquid, result in mispricing and additional legal, financial, tax, operational, market, compliance, reputational, competitive or other risks to us, our clients and other market participants. There is no guarantee that liquidity in ARR-based products will develop, and it is possible that ARR-based products will perform differently to IBOR Products during times of economic stress, adverse or volatile market conditions and across the credit and economic cycle, which may impact the value, return on and profitability of our ARR-based assets.
Failure to meet industry-wide IBOR transition milestones and to cease issuance of IBOR Products by relevant cessation dates may, subject to certain regulatory exceptions, result in supervisory enforcement by applicable regulators, increase our cost of, and access to, capital and other consequences. In addition, IBOR Products held by us may become less liquid as the transition process develops, and other unforeseen consequences may arise if such products are held beyond relevant cessation dates.
Changes or uncertainty resulting from the market transition from IBORs to ARRs could adversely affect the return on and pricing, liquidity and value of outstanding IBOR Products, cause significant market dislocations and disruptions, potentially increase the cost of and access to capital, increase the risk of litigation or other disputes, including in connection with the interpretation and enforceability of, or our historical marketing practices or disclosures with respect to outstanding IBOR products with counterparties, and/or increase expenses related to the transition to ARRs, among other adverse consequences.
The market transition may also alter our risk profile and risk management strategies, including derivatives and hedging strategies, modeling and analytics, valuation tools, product design and systems, controls, procedures and operational infrastructure. This may prove challenging given the limited history of many of the proposed ARRs and may increase the costs and risks related to potential regulatory compliance, requirements or inquiries. Among other risks, various products and contracts may transition to ARRs at different times or in different manners, with the result that we may face significant unexpected interest rate, pricing or other exposures across business or product lines. Reforms to and uncertainty regarding market transition and other factors may adversely affect our business, including the ability to serve customers and maintain market share, financial condition or results of operations and could result in reputational harm to the Corporation.
We face significant and increasing competition in the financial services industry.
We operate in a highly competitive environment and experience intense competition from local and global financial institutions as well as new entrants, in both domestic and foreign markets, in which we compete on the basis of a number of factors, including customer service, quality and range of products and services offered, technology, price, fees, reputation, interest rates on loans and deposits, lending limits and customer convenience. Additionally, the changing regulatory environment may create competitive disadvantages for us given geography-driven capital and liquidity requirements. Additionally, we may face competitors with more experience and established relationships in the relevant market, which could adversely affect our ability to compete.
In addition, emerging technologies and advances and the growth of e-commerce have lowered geographic and monetary barriers of other financial institutions, made it easier for non-depository institutions to offer products and services that traditionally were banking products and allowed non-traditional financial service providers and technology companies to compete with traditional financial service companies in providing electronic and internet-based financial solutions and services, including electronic securities trading with low or no fees and commissions, marketplace lending, financial data aggregation and payment processing, including real-time payment platforms. Further, clients may choose to conduct business with other market participants who engage in business or offer products in areas we deem speculative or risky, such as cryptocurrencies. Increased competition may negatively affect our earnings by creating pressure to lower prices, fees, commissions or credit standards on our products and services requiring additional investment to improve the quality and delivery of our technology and/or reducing our market share, or affecting the willingness of our clients to do business with us.
Our inability to adapt our products and services could harm our business.
Our business model is based on a diversified mix of businesses that provide a broad range of financial products and services, delivered through multiple distribution channels. Our success depends on our, and our third-party vendors', ability to adapt and develop products, services and technology to rapidly evolving industry standards and consumer preferences. In particular, the emergence of the pandemic has resulted in increased reliance on digital banking and other digital services provided by the Corporation’s businesses. There is increasing pressure by competitors to provide products and services on more attractive terms, including higher interest rates on deposits, and offer lower cost investment strategies, which may impact our ability to grow revenue and/or effectively compete. Additionally, legislative and regulatory developments may affect the competitive landscape. Further, the competitive landscape may be impacted by the growth of non-depository institutions that offer traditional banking products at higher rates or with low or no fees, or otherwise offer alternative products. This can reduce our net interest margin and revenues from our fee-based products and services, either from a decrease in the volume of transactions or through a compression of spreads.
In addition, the widespread adoption and rapid evolution of new technologies, including analytic capabilities, self-service digital trading platforms, internet services, distributed ledgers, such as the blockchain system, cryptocurrencies and payment systems, could require substantial expenditures to modify or adapt our existing products and services as we grow and develop our online and mobile banking channel strategies in
Bank of America 20


addition to remote connectivity solutions. We may not be as timely or successful in developing or introducing new products and services, integrating new products or services into our existing offerings, responding or adapting to changes in consumer behavior, preferences, spending, investing and/or saving habits, achieving market acceptance of our products and services, reducing costs in response to pressures to deliver products and services at lower prices or sufficiently developing and maintaining loyal customers. The Corporation’s or its third-party vendors' inability to adapt products and services to evolving industry standards and consumer preferences could result in service disruptions and harm our business and adversely affect our results of operations and reputation.
We could suffer operational, reputational and financial harm if our models and strategies fail to properly anticipate and manage risk.
We use proprietary models and strategies extensively to forecast losses, project revenue, measure and assess capital requirements for credit, country, market, operational and strategic risks and assess and control our operations and financial condition. Model risk management is a dedicated and independent risk function that defines model risk governance, policy and guidelines for the Corporation based on laws, rules and regulations, as well as internal requirements. Under the Corporation's Enterprise Model Risk Policy, model risk management is required to perform model oversight, including independent validation before initial use, ongoing monitoring through outcomes analysis and benchmarking, and periodic revalidation. Models are subject to inherent limitations due to the use of historical trends and simplifying assumptions, uncertainty regarding economic and financial outcomes, and emerging risks from the use of applications that rely on AI.
Our models and strategies may not be sufficiently predictive of future results due to limited historical patterns, extreme or unanticipated market movements or customer behavior and liquidity, especially during severe market downturns or stress events, which could limit their effectiveness. The models that we use to assess and control our market risk exposures also reflect assumptions about the degree of correlation among prices of various asset classes or other market indicators, which may not be representative of the next downturn and would magnify the limitations inherent in using historical data to manage risk. Our models may not be effective if we fail to properly oversee them and detect their flaws during our review and monitoring processes, they contain erroneous data, assumptions, valuations, formulas or algorithms or our applications running the models do not perform as expected. Regardless of the steps we take to ensure effective controls, governance, monitoring and testing, and implement new
technology and automated processes, we could suffer operational, reputational and financial harm if models and strategies fail to properly anticipate and manage current and evolving risks.
Failure to properly manage and aggregate data may result in our inability to manage risk and business needs, errors in our day-to-day operations, critical reporting and strategic decision-making and inaccurate reporting.
We rely on our ability to manage, surveil, aggregate, interpret and use data in an accurate, timely and complete manner for effective risk reporting and management. Our policies, programs, processes and practices govern how data is surveilled, managed, aggregated, interpreted and used. While we continuously update our policies, programs, processes and practices and implement emerging technologies, such as
automation, AI and robotics, our data management and aggregation processes are subject to failure, including human error, system failure or failed controls. Failure to surveil, maintain and manage data and information effectively and to aggregate data and information in an accurate, timely and complete manner may impact its quality and reliability and limit our ability to manage current and emerging risk, to produce accurate financial, regulatory and operational reporting, as well as to manage changing business needs, strategic decision-making and day-to-day operations. The failure to establish and maintain effective, efficient and controlled data management could adversely impact our ability to develop our products and relationships with our customers and damage our reputation.
Our operations, businesses and customers could be materially adversely affected by the impacts related to climate change.
There is an increasing concern over the risks of climate change and related environmental sustainability matters. The physical risks of climate change include rising average global temperatures, rising sea levels and an increase in the frequency and severity of extreme weather events and natural disasters, including floods, wildfires, hurricanes and tornados. Such disasters could disrupt our operations or the operations of customers or third parties on which we rely. Such disasters could result in market volatility or negatively impact our customers’ ability to pay outstanding loans, damage collateral or result in the deterioration of the value of collateral or insurance shortfalls. Additionally, climate change concerns could result in transition risk. Changes in consumer preferences and additional legislation and regulatory requirements, including those associated with the transition to a low-carbon economy, could increase expenses or otherwise adversely impact the Corporation, its businesses or its customers. We could also experience increased expenses resulting from strategic planning, litigation and technology and market changes, and reputational harm as a result of negative public sentiment, regulatory scrutiny and reduced investor and stakeholder confidence due to our response to climate change and our climate change strategy.
Our ability to attract and retain qualified employees is critical to our success, business prospects and competitive position.
Our performance is heavily dependent on the talents and efforts of highly skilled individuals. Competition for qualified personnel within the financial services industry and from businesses outside the financial services industry is intense.
Our competitors include non-U.S. based institutions and institutions subject to different compensation and hiring regulations than those imposed on U.S. institutions and financial institutions.
In order to attract and retain qualified personnel, we must provide market-level compensation. As a large financial and banking institution, we are and may become subject to additional limitations on compensation practices, which may or may not affect our competitors, by the Federal Reserve, the OCC, the FDIC and other regulators around the world. EU and U.K. rules limit and subject to clawback certain forms of variable
compensation for senior employees. Furthermore, a substantial portion of our annual incentive compensation paid to our senior employees consists of long-term equity-based awards, the value of which is based on the price of our common stock when the awards vest. Our business prospects and competitive position could be adversely affected if we cannot attract and retain qualified individuals.

Management’s Discussion and Analysis of Financial Condition and Results of Operations
Bank of America Corporation (the “Corporation”) and its management may make certain statements that constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements can be identified by the fact that they do not relate strictly to historical or current facts. Forward-looking statements often use words such as “anticipates,” “targets,” “expects,” “hopes,” “estimates,” “intends,” “plans,” “goals,” “believes,” “continue” and other similar expressions or future or conditional verbs such as “will,” “may,” “might,” “should,” “would” and “could.” Forward-looking statements represent the Corporation’s current expectations, plans or forecasts of its future results, revenues, provision for credit losses, expenses, efficiency ratio, capital measures, strategy and future business and economic conditions more generally, and other future matters. These statements are not guarantees of future results or performance and involve certain known and unknown risks, uncertainties and assumptions that are difficult to predict and are often beyond the Corporation’s control. Actual outcomes and results may differ materially from those expressed in, or implied by, any of these forward-looking statements.
You should not place undue reliance on any forward-looking statement and should consider the following uncertainties and risks, as well as the risks and uncertainties more fully discussed under Item 1A. Risk Factors of this Annual Report on Form 10-K: the Corporation’s potential judgments, damages, penalties, fines and reputational damage resulting from pending or future litigation, regulatory proceedings and enforcement actions; the possibility that the Corporation's future liabilities may be in excess of its recorded liability and estimated range of possible loss for litigation, and regulatory and government actions, including as a result of our participation in and execution of government programs related to the Coronavirus Disease 2019 (COVID-19) pandemic; the possibility that the Corporation could face increased claims from one or more parties involved in mortgage securitizations; the Corporation’s ability to resolve representations and warranties repurchase and related claims; the risks related to the discontinuation of the London Interbank Offered Rate and other reference rates, including increased expenses and litigation and the effectiveness of hedging strategies; uncertainties about the financial stability and growth rates of non-U.S. jurisdictions, the risk that those jurisdictions may face difficulties servicing their sovereign debt, and related stresses on financial markets, currencies and trade, and the Corporation’s exposures to such risks, including direct, indirect and operational; the impact of U.S. and global interest rates, inflation, currency exchange rates, economic conditions, trade policies and tensions, including tariffs, and potential geopolitical instability; the impact of the interest rate environment on the Corporation’s business, financial condition and results of operations; the possibility that future credit losses may be higher than currently expected due to changes in economic assumptions, customer behavior, adverse developments with respect to U.S. or global economic conditions and other uncertainties; the Corporation's concentration of credit risk; the Corporation’s ability to achieve its expense targets and expectations regarding revenue, net interest income, provision for credit losses, net charge-offs, effective tax rate, loan growth or other projections; adverse changes to the Corporation’s credit ratings from the major credit rating agencies; an inability to access capital markets or maintain deposits or borrowing costs; estimates of the fair value and other accounting values, subject to impairment assessments, of certain of the Corporation’s assets
and liabilities; the estimated or actual impact of changes in accounting standards or assumptions in applying those standards; uncertainty regarding the content, timing and impact of regulatory capital and liquidity requirements; the impact of adverse changes to total loss-absorbing capacity requirements, stress capital buffer requirements and/or global systemically important bank surcharges; the potential impact of actions of the Board of Governors of the Federal Reserve System on the Corporation’s capital plans; the effect of regulations, other guidance or additional information on the impact from the Tax Cuts and Jobs Act; the impact of implementation and compliance with U.S. and international laws, regulations and regulatory interpretations, including, but not limited to, recovery and resolution planning requirements, Federal Deposit Insurance Corporation assessments, the Volcker Rule, fiduciary standards, derivatives regulations and the Coronavirus Aid, Relief, and Economic Security Act and any similar or related rules and regulations; a failure or disruption in or breach of the Corporation’s operational or security systems or infrastructure, or those of third parties, including as a result of cyber attacks or campaigns; the impact on the Corporation’s business, financial condition and results of operations from the United Kingdom's exit from the European Union; the impact of climate change; the impact of any future federal government shutdown and uncertainty regarding the federal government’s debt limit or changes to the U.S. presidential administration and Congress; the emergence of widespread health emergencies or pandemics, including the magnitude and duration of the COVID-19 pandemic and its impact on the U.S. and/or global, financial market conditions and our business, results of operations, financial condition and prospects; the impact of natural disasters, extreme weather events, military conflict, terrorism or other geopolitical events; and other matters.
Forward-looking statements speak only as of the date they are made, and the Corporation undertakes no obligation to update any forward-looking statement to reflect the impact of circumstances or events that arise after the date the forward-looking statement was made.

Recent Developments
Capital Management
In June 2020, the Board of Governors of the Federal Reserve System (Federal Reserve) notified BHCs of their 2020 Comprehensive Capital Analysis and Review (CCAR) supervisory stress test results. Due to economic uncertainty resulting from the Coronavirus Disease 2019 (COVID-19) pandemic (the pandemic), the Federal Reserve required all large banks to update and resubmit their capital plans in November 2020 based on the Federal Reserve’s updated supervisory stress test scenarios. The results of the additional supervisory stress tests were published in December 2020.
The Federal Reserve also required large banks to suspend share repurchase programs during the second half of 2020, except for repurchases to offset shares awarded under equity-based compensation plans, and to limit common stock dividends to existing rates that did not exceed the average of the last four quarters’ net income. In December 2020, the Federal Reserve announced that beginning in the first quarter of 2021, large banks would be permitted to pay common stock dividends at existing rates and to repurchase shares in an amount that, when combined with dividends paid, does not exceed the average of net income over the last four quarters.
On January 19, 2021, we announced that the Board of Directors (the Board) declared a quarterly common stock dividend of $0.18 per share, payable on March 26, 2021 to shareholders of record as of March 5, 2021. We also announced that the Board authorized the repurchase of $2.9 billion in common stock through March 31, 2021, plus repurchases to offset shares awarded under equity-based compensation plans during the same period, estimated to be approximately $300 million. This authorization equals the maximum amount allowed by the Federal Reserve for the period. For more information, see Capital Management on page 50.
COVID-19 Pandemic
In the first quarter of 2020, the World Health Organization declared the outbreak of COVID-19 a pandemic. In an attempt to contain the spread and impact of the pandemic, travel bans and restrictions, quarantines, shelter-in-place orders and other limitations on business activity were implemented. Additionally, there has been a decline in global economic activity, reduced U.S. and global economic output and a deterioration in macroeconomic conditions in the U.S. and globally. This has
resulted in, among other things, higher rates of unemployment and underemployment and caused volatility and disruptions in the global financial markets, including the energy and commodity markets. Although vaccines have been approved for immunization against COVID-19 in certain countries and restrictive measures have been eased in certain areas, COVID-19 cases have significantly increased in recent months in the U.S. and many regions of the world compared to earlier levels. Businesses, market participants, our counterparties and clients, and the U.S. and global economies have been negatively impacted and are likely to be so for an extended period of time, as there remains significant uncertainty about the timing and strength of an economic recovery.
To address the economic impact in the U.S., in March and April 2020, four economic stimulus packages were enacted to provide relief to businesses and individuals, including the Coronavirus Aid, Relief, and Economic Security Act (CARES Act). Among other measures, the CARES Act established the Small Business Administration (SBA) Paycheck Protection Program (PPP), which provides loans to small businesses to keep their employees on payroll and make other eligible payments. The original funding for the PPP under the CARES Act was fully allocated by mid-April 2020, with additional funding made available on April 24, 2020 under the Paycheck Protection Program and Health Care Enhancement Act. In December 2020, an additional economic stimulus package was included as part of the Consolidated Appropriations Act of 2021 (the Consolidated Appropriations Act), which provides relief to individuals and businesses. This relief included additional funding for the PPP under the Economic Aid to Hard-Hit Small Businesses, Nonprofits, and Venues Act (the Economic Aid Act).
In response to the pandemic, the Corporation has implemented protocols and processes to execute its business continuity plans and help protect its employees and support its clients. The Corporation is managing its response to the pandemic according to its Enterprise Response Framework, which invokes centralized management of the crisis event and the integration of its response. The CEO and key members of the Corporation’s management team meet regularly with co-leaders of the Executive Response Team, which is composed of senior executives across the Corporation, to help drive decisions, communications and consistency of response across all businesses and functions. We are also coordinating with global, regional and local authorities and health experts, including the U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization.
Additionally, we have implemented a number of measures to assist our employees, clients and the communities we serve as discussed below.
Employees
We are providing support to our teammates to help promote the health and safety of our employees and help to ensure our protocols remain aligned to current guidance by monitoring guidance from the CDC, medical boards and health authorities and sharing such guidance with our employees. We are also operating our businesses from remote locations and leveraging our business continuity plans and capabilities.
The Corporation has globally implemented a work-from-home posture, which has resulted in the substantial majority of our employees working from home, and pre-planned contingency strategies for site-based operations for our remaining employees. We continue to evaluate our continuity plans and work-from-home strategy in an effort to best protect the health and safety of our employees.
25 Bank of America


Clients
We continue to leverage our business continuity plans and capabilities to service our clients and meet our clients’ financial needs by offering assistance to clients affected by the pandemic, including providing access to credit and the important financial services on which our clients rely. We are also participating in the programs created by the CARES Act and Federal Reserve lending programs for businesses, including originating PPP loans. We have also participated in the Main Street Lending Program, which ended on January 8, 2021. While most of our deferral programs expired in the third quarter of 2020, we continue to offer assistance on a case-by-case basis when requested by clients affected by the pandemic.
As of December 31, 2020, we had approximately 332,000 PPP loans outstanding with a carrying value of $22.7 billion, which were recorded in the Consumer, GWIM and Global Banking segments. Since the PPP's inception through February 17, 2021, borrowers have submitted applications for forgiveness to us for approximately 113,000 PPP loans with balances totaling $10.9 billion. We have submitted approximately 72,000 PPP loans with balances totaling $8.5 billion to the SBA for repayment, of which we have received to date $5.4 billion in repayment from the SBA. Additionally, as of February 17, 2021, we have originated $4.1 billion in PPP loans under the Economic Aid Act.

We continue to support the communities where we live and work by engaging in various initiatives to help those affected by COVID-19. These initiatives include committing resources to provide medical supplies, food and other necessities for those in need. We are also supporting racial equality, economic opportunity and environmental sustainability through direct equity investments in minority-owned depository institutions, equity investments in minority entrepreneurs, businesses and funds, as well as other initiatives.
Risk Management
We continue to manage the increased operational risk related to the execution of our business continuity plans in accordance with our Enterprise Response Framework, Risk Framework and Operational Risk Management Program. For more information, see Managing Risk on page 47.
Loan Modifications
The Corporation has implemented various consumer and commercial loan modification programs to provide its borrowers relief from the economic impacts of COVID-19. Based on guidance in the CARES Act that the Corporation adopted, COVID-19 related modifications to consumer and commercial loans that were current as of December 31, 2019 are exempt from troubled debt restructuring (TDR) classification under accounting principles generally accepted in the United States of America (GAAP). In addition, the bank regulatory agencies issued interagency guidance stating that COVID-19 related short-term modifications (i.e., six months or less) granted to consumer or commercial loans that were current as of the loan modification program implementation date are not TDRs. In December 2020, the Consolidated Appropriations Act amended the CARES Act by extending the exemption from TDR classification for COVID-19 related modifications from December 31, 2020 to the earlier of January 1, 2022 or 60 days after the national emergency has ended. For more information, see Note
1 – Summary of Significant Accounting Principles and Note 5 – Outstanding Loans and Leases and Allowance for Credit Losses to the Consolidated Financial Statements.
We have provided borrowers with relief from the economic impacts of COVID-19 through payment deferral and forbearance programs. A significant portion of deferrals expired during the second half of 2020, reflecting a decline in customer requests for assistance. As of February 17, 2021, deferred consumer and small business loans recorded on the Consolidated Balance Sheet totaled $6.8 billion, predominantly consisting of $6.4 billion of residential mortgage and home equity loans, including loans serviced by others, that are well-collateralized.
Other Related Matters
Although the macroeconomic outlook improved modestly during the second half of 2020, the future direct and indirect impact of COVID-19 on our businesses, results of operations and financial condition of the Corporation remains highly uncertain. Should current economic conditions persist or deteriorate, this macroeconomic environment will have a continued adverse effect on our businesses and results of operations and could have an adverse effect on our financial condition. For more information on how the risks related to the pandemic may adversely affect our businesses, results of operations and financial condition, see Part I. Item 1A. Risk Factors on page 7.
LIBOR and Other Benchmark Rates
Following the 2017 announcement by the U.K.’s Financial Conduct Authority (FCA) that it would no longer compel participating banks to submit rates for the London Interbank Offered Rate (LIBOR) after 2021, regulators, trade associations and financial industry working groups have identified recommended replacement rates for LIBOR, as well as other Interbank Offered Rates (IBORs), and have published recommended conventions to allow new and existing products to incorporate fallbacks or that reference these Alternative Reference Rates (ARRs). The continuation of all British Pound Sterling, Euro, Swiss Franc and Japanese Yen LIBOR settings and one-week and two-month U.S. dollar LIBOR settings on the current basis are expected to terminate at the end of December 2021, and the remaining U.S. dollar LIBOR settings (i.e., overnight, one month, three month, six month and 12 month) are expected to terminate at the end of June 2023.
As a result of this and other announcements, financial benchmark reforms, regulatory guidance and changes in short-term interbank lending markets more generally, a major transition is in progress in global financial markets with respect to the replacement of IBORs and certain benchmarks. The transition of IBORs to ARRs is a complex process impacting a variety of global financial markets and our business and operations.
IBORs are used in many of the Corporation’s products and contracts, including derivatives, consumer and commercial loans, mortgages, floating-rate notes and other adjustable-rate products and financial instruments. The discontinuation of IBORs requires us to transition a significant number of IBOR-based products and contracts, including related hedging arrangements. In response, the Corporation established an enterprise-wide IBOR transition program led by senior management in early 2018. This program, which is led by the Corporation's Chief Operating Officer, includes active involvement of senior management and regular reports to the Enterprise Risk Committee (ERC). The program is intended to address the Corporation's industry and regulatory engagement, client and financial contract changes, internal and external communications, technology and operations modifications,
Bank of America 26


introduction of new products, migration of existing clients, and program strategy and governance. In addition, the program is designed to monitor a variety of scenarios, including operational risks associated with insufficient preparation by individual market participants or the overall market ecosystem, volatility along the Secured Overnight Financing Rate (SOFR) curve, development and adoption of credit-sensitive and other rates, regulatory and legal uncertainty with respect to various matters including contract continuity, access by market participants to liquidity in certain products, and IBOR continuity beyond December 2021.
As of February 1, 2021, a significant majority of the aggregate notional amount of our LIBOR-based products and contracts maturing after 2021 include or have been updated to include fallbacks to ARRs based on market driven protocols, regulatory guidance and industry-recommended fallback provisions and related mechanisms. For certain of the remaining products and contracts, the transition will be more complex, particularly where there is no industry-wide protocol or similar mechanism. The Corporation is executing transition plans that are intended to be in line with applicable major industry-wide IBOR product cessation and launch milestones recommended by the Alternative Reference Rates Committee, a group of private market participants and official sector entities convened by the Federal Reserve and the Federal Reserve Bank of New York, and the Bank of England Sterling Risk Free Rate Working Group, other than the cessation of LIBOR-based adjustable-rate consumer mortgages. The Corporation plans to no longer offer these mortgages and launch SOFR-based adjustable-rate consumer mortgages by the end of the first quarter of 2021.
The Corporation is executing product and client roadmaps that it believes align with industry-recommended and regulatory milestones, and the Corporation has developed employee training programs as well as other internal and external sources of information on the various challenges and opportunities that the replacement of IBORs presents. As the transition to ARRs evolves, the Corporation continues to monitor and participate in the development and usage of certain ARRs, including SOFR, the Euro Short Term Rate and the Sterling Overnight Index Average (SONIA). The Corporation’s key transition efforts to date include issuances of debt and deposits linked to SOFR and SONIA by the Corporation, facilitating debt issuances linked to ARRs by clients and secondary market liquidity for products linked to ARRs, originating and arranging loans linked to ARRs, including hedging arrangements, executing, trading, market making and clearing ARR-based derivatives, and launching capabilities and services to support the issuance and trading in products indexed to certain ARRs. The Corporation updated its operational models, systems, procedures and internal infrastructure in connection with the transition to ARRs by the central clearing counterparties. In October 2020, the Corporation and certain of its subsidiaries adhered to the International Swaps and Derivatives Association, Inc. 2020 IBOR Fallbacks Protocol, effective January 25, 2021, which provides a mechanism to enable market participants to incorporate fallbacks for certain legacy non-cleared derivatives linked to certain IBORs.
Additionally, the Corporation is continuing to evaluate potential regulatory, tax and accounting impacts of the transition, including guidance published and/or proposed by the Internal Revenue Service and Financial Accounting Standards Board, engage impacted clients in connection with the transition to ARRs and work actively with global regulators, industry working groups and trade associations to develop strategies for an effective transition to ARRs. For more information on the
expected replacement of LIBOR and other benchmark rates, see Item 1A. Risk Factors – Other on page 19.
U.K. Exit from the EU
On January 31, 2020, the U.K. formally exited the European Union (EU), and a transition period began during which time the U.K. and the EU negotiated a trade agreement and other terms associated with their future relationship. The transition period ended on December 31, 2020.
We conduct business in Europe, the Middle East and Africa primarily through our subsidiaries in the U.K., Ireland and France and implemented changes to enable us to continue to operate in the region, including establishing a bank and broker-dealer in the EU, as well as minimize the potential for any operational disruption. As the global economic impact of the U.K.’s withdrawal from the EU remains uncertain and could result in regional and global financial market disruptions, we continue to assess potential operational, regulatory and legal risks. For more information, see Item 1A. Risk Factors – Geopolitical on page 12.
Financial Highlights
Effective January 1, 2020, we adopted the new accounting standard on current expected credit losses (CECL), under which the allowance is measured based on management’s best estimate of lifetime expected credit losses (ECL). Prior-year periods presented reflect measurement of the allowance based on management’s estimate of probable incurred credit losses. For more information, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements.

Net income was $17.9 billion or $1.87 per diluted share in 2020 compared to $27.4 billion or $2.75 per diluted share in 2019. The decline in net income was primarily due to higher provision for credit losses driven by the weaker economic outlook related to COVID-19 and lower net interest income.
For discussion and analysis of our consolidated and business segment results of operations for 2019 compared to 2018, see the Financial Highlights and Business Segment Operations sections in the MD&A of the Corporation's 2019 Annual Report on Form 10-K.
Net Interest Income
Net interest income decreased $5.5 billion to $43.4 billion in 2020 compared to 2019. Net interest yield on a fully taxable-equivalent (FTE) basis decreased 53 basis points (bps) to 1.90 percent for 2020. The decrease in net interest income was primarily driven by lower interest rates, partially offset by reduced deposit and funding costs, the deployment of excess deposits into securities and an additional day of interest accrual. Assuming continued economic improvement and based on the forward interest rate curve as of January 19, 2021, when we announced quarterly and annual results for the periods ended December 31, 2020, we expect net interest income to be higher in the second half of 2021 as compared to both the second half of 2020 and the first half of 2021. For more information on net interest yield and the FTE basis, see Supplemental Financial Data on page 31, and for more information on interest rate risk management, see Interest Rate Risk Management for the Banking Book on page 82.

Noninterest income decreased $185 million to $42.2 billion in 2020 compared to 2019. The following highlights the significant changes.
    Card income decreased $141 million primarily due to lower levels of consumer spending driven by the impact of COVID-19, partially offset by higher income related to the processing of unemployment insurance.
    Service charges decreased $533 million primarily due to higher deposit balances and lower client activity due to the impact of COVID-19.
●    Investment and brokerage services income increased $672 million primarily due to higher client transactional activity, higher market valuations and assets under management (AUM) flows, partially offset by declines in AUM pricing.
    Investment banking fees increased $1.5 billion primarily driven by higher equity issuance fees.
    Market making and similar activities decreased $679 million primarily due to the impact of lower U.S. interest rates on certain risk management derivatives, partially offset by increased client activity and strong trading performance in fixed income, currencies and commodities (FICC).
    Other income decreased $1.0 billion primarily due to lower equity investment income, higher partnership losses on tax credit investments, primarily affordable housing and renewable energy, partially offset by higher gains on loan sales and sales of debt securities.
Provision for Credit Losses
The provision for credit losses increased $7.7 billion to $11.3 billion in 2020 compared to 2019 primarily driven by higher ECL due to a weaker economic outlook related to COVID-19. For more information on the provision for credit losses, see Allowance for Credit Losses on page 76.

Total noninterest expense $ 55,213  $ 54,900 
Noninterest expense increased $313 million to $55.2 billion in 2020 compared to 2019. The increase was primarily due to higher operating costs related to COVID-19, merchant services expenses, which were previously recorded in other income as part of joint venture net earnings, and higher activity-based expenses due to increased client activity, partially offset by a $2.1 billion pretax impairment charge related to the notice of termination of the merchant services joint venture in 2019.

The change in the effective tax rate for 2020 was driven by the impact of our recurring tax preference benefits on lower levels of pretax income. These benefits primarily consist of tax credits from environmental, social and governance (ESG) investments in affordable housing and renewable energy, aligning with our responsible growth strategy to address global sustainability challenges. Excluding tax credits related to our ESG investment activity, the effective tax rate for 2020 would have been 21 percent.
The 2020 rate also included the impact of the U.K. tax law change, whereby on July 22, 2020, the U.K. enacted a repeal of the final two percent of scheduled decreases in the U.K. corporation tax rate, which had been previously enacted. This change will unfavorably affect income tax expense on future U.K.
earnings, and requires a reversal of the adjustment to the U.K. net deferred tax assets recognized at the time the tax rate decreases were originally enacted. Accordingly, during the third quarter of 2020, the Corporation recorded an income tax benefit of approximately $700 million along with a corresponding increase to the U.K. net deferred tax assets.
The effective tax rate for 2019 included net tax benefits primarily related to the resolution of various tax controversy matters.
Absent unusual items, we expect the effective tax rate for 2021 to be in the range of 10 12 percent, reflecting tax credits related to our ESG investment activity.

Assets
At December 31, 2020, total assets were approximately $2.8 trillion, up $385.5 billion from December 31, 2019. The increase in assets was primarily due to higher cash held at central banks that was primarily funded by deposit growth and debt securities, partially offset by a decline in loans and leases.
Cash and Cash Equivalents
Cash and cash equivalents increased $218.9 billion driven by deposit growth.
Federal Funds Sold and Securities Borrowed or Purchased Under Agreements to Resell
Federal funds transactions involve lending reserve balances on a short-term basis. Securities borrowed or purchased under agreements to resell are collateralized lending transactions utilized to accommodate customer transactions, earn interest rate spreads, and obtain securities for settlement and for collateral. Federal funds sold and securities borrowed or purchased under agreements to resell increased $29.5 billion primarily due to deployment of deposit inflows.

Trading Account Assets
Trading account assets consist primarily of long positions in equity and fixed-income securities including U.S. government and agency securities, corporate securities and non-U.S. sovereign debt. Trading account assets decreased $31.0 billion due to a decline in inventory within Global Markets.
Debt Securities
Debt securities primarily include U.S. Treasury and agency securities, mortgage-backed securities (MBS), principally agency MBS, non-U.S. bonds, corporate bonds and municipal debt. We use the debt securities portfolio primarily to manage interest rate and liquidity risk and to take advantage of market conditions that create economically attractive returns on these investments. Debt securities increased $212.7 billion primarily driven by the deployment of deposit inflows. For more information on debt securities, see Note 4 – Securities to the Consolidated Financial Statements.

29 Bank of America


Loans and Leases
Loans and leases decreased $55.6 billion primarily driven by commercial loan paydowns, lower credit card spending and lower residential mortgages due to higher paydowns and a decline in originations. For more information on the loan portfolio, see Credit Risk Management on page 61.
Allowance for Loan and Lease Losses
The allowance for loan and lease losses increased $9.4 billion primarily due to the weaker economic outlook related to COVID-19 and the impact of the adoption of the new credit loss accounting standard. For more information, see Allowance for Credit Losses on page 76.
Liabilities
At December 31, 2020, total liabilities were approximately $2.5 trillion, up $377.4 billion from December 31, 2019, primarily due to deposit growth.
Deposits
Deposits increased $360.7 billion primarily due to an increase in retail and wholesale deposits.
Federal Funds Purchased and Securities Loaned or Sold Under Agreements to Repurchase
Federal funds transactions involve borrowing reserve balances on a short-term basis. Securities loaned or sold under agreements to repurchase are collateralized borrowing transactions utilized to accommodate customer transactions, earn interest rate spreads and finance assets on the balance sheet. Federal funds purchased and securities loaned or sold under agreements to repurchase increased $5.2 billion primarily driven by client activity within Global Markets.
Trading Account Liabilities
Trading account liabilities consist primarily of short positions in equity and fixed-income securities including U.S. Treasury and agency securities, corporate securities and non-U.S. sovereign debt. Trading account liabilities decreased $12.0 billion primarily due to lower levels of short positions within Global Markets.

Short-term Borrowings
Short-term borrowings provide an additional funding source and primarily consist of Federal Home Loan Bank (FHLB) short-term borrowings, notes payable and various other borrowings that generally have maturities of one year or less. Short-term borrowings decreased $4.9 billion due to higher deposit levels. For more information on short-term borrowings, see Note 10 – Federal Funds Sold or Purchased, Securities Financing Agreements, Short-term Borrowings and Restricted Cash to the Consolidated Financial Statements.
Long-term Debt
Long-term debt increased $22.1 billion primarily due to debt issuances and valuation adjustments, partially offset by maturities and redemptions. For more information on long-term debt, see Note 11 – Long-term Debt to the Consolidated Financial Statements.
Shareholders’ Equity
Shareholders’ equity increased $8.1 billion driven by net income, market value increases on debt securities and issuances of preferred and common stock, partially offset by the return of capital to shareholders totaling $14.7 billion through share repurchases and common and preferred stock dividends, as well as the impact of the adoption of the new credit loss accounting standard and the redemption of preferred stock.
Cash Flows Overview
The Corporation’s operating assets and liabilities support our global markets and lending activities. We believe that cash flows from operations, available cash balances and our ability to generate cash through short- and long-term debt are sufficient to fund our operating liquidity needs. Our investing activities primarily include the debt securities portfolio and loans and leases. Our financing activities reflect cash flows primarily related to customer deposits, securities financing agreements and long-term debt. For more information on liquidity, see Liquidity Risk on page 57.

Supplemental Financial Data
Non-GAAP Financial Measures
In this Form 10-K, we present certain non-GAAP financial measures. Non-GAAP financial measures exclude certain items or otherwise include components that differ from the most directly comparable measures calculated in accordance with GAAP. Non-GAAP financial measures are provided as additional useful information to assess our financial condition, results of operations (including period-to-period operating performance) or compliance with prospective regulatory requirements. These non-GAAP financial measures are not intended as a substitute for GAAP financial measures and may not be defined or calculated the same way as non-GAAP financial measures used by other companies.
We view net interest income and related ratios and analyses on an FTE basis, which when presented on a consolidated basis are non-GAAP financial measures. To derive the FTE basis, net interest income is adjusted to reflect tax-exempt income on an equivalent before-tax basis with a corresponding increase in income tax expense. For purposes of this calculation, we use the federal statutory tax rate of 21 percent and a representative state tax rate. Net interest yield, which measures the basis points we earn over the cost of funds, utilizes net interest income on an FTE basis. We believe that presentation of these items on an FTE basis allows for comparison of amounts from both taxable and tax-exempt sources and is consistent with industry practices.
We may present certain key performance indicators and ratios excluding certain items (e.g., debit valuation adjustment (DVA) gains (losses)) which result in non-GAAP financial measures. We believe that the presentation of measures that exclude these items is useful because such measures provide additional information to assess the underlying operational performance and trends of our businesses and to allow better comparison of period-to-period operating performance.
We also evaluate our business based on certain ratios that utilize tangible equity, a non-GAAP financial measure. Tangible equity represents shareholders’ equity or common shareholders’ equity reduced by goodwill and intangible assets (excluding mortgage servicing rights (MSRs)), net of related deferred tax liabilities ("adjusted" shareholders' equity or common shareholders' equity). These measures are used to evaluate our use of equity. In addition, profitability, relationship and investment models use both return on average tangible common shareholders’ equity and return on average tangible
shareholders’ equity as key measures to support our overall growth objectives. These ratios are as follows:
    Return on average tangible common shareholders’ equity measures our net income applicable to common shareholders as a percentage of adjusted average common shareholders’ equity. The tangible common equity ratio represents adjusted ending common shareholders’ equity divided by total tangible assets.
    Return on average tangible shareholders' equity measures our net income as a percentage of adjusted average total shareholders’ equity. The tangible equity ratio represents adjusted ending shareholders’ equity divided by total tangible assets.
    Tangible book value per common share represents adjusted ending common shareholders’ equity divided by ending common shares outstanding.
We believe ratios utilizing tangible equity provide additional useful information because they present measures of those assets that can generate income. Tangible book value per common share provides additional useful information about the level of tangible assets in relation to outstanding shares of common stock.
The aforementioned supplemental data and performance measures are presented in Tables 6 and 7.
For more information on the reconciliation of these non-GAAP financial measures to the corresponding GAAP financial measures, see Non-GAAP Reconciliations on page 88.
Key Performance Indicators
We present certain key financial and nonfinancial performance indicators (key performance indicators) that management uses when assessing our consolidated and/or segment results. We believe they are useful to investors because they provide additional information about our underlying operational performance and trends. These key performance indicators (KPIs) may not be defined or calculated in the same way as similar KPIs used by other companies. For information on how these metrics are defined, see Key Metrics on page 173.
Our consolidated key performance indicators, which include various equity and credit metrics, are presented in Table 1 on page 27 and/or Tables 6 and 7 on pages 32 and 33.
For information on key segment performance metrics, see Business Segment Operations on page 36.
