Consolidated Financial Highlights (Continued)

(1) Pre-tax, pre-provision income (loss) is total revenue less noninterest expense. Management believes that this is a useful financial measure because it enables investors and others to assess the Company's ability to generate capital to cover credit losses through a credit cycle.

(2) Annualized.

(3) Return on tangible common equity, a non-GAAP financial measure, is net income (loss) excluding intangible asset amortization divided by average tangible common equity. Management believes that this ratio provides useful supplemental information regarding the Company's business results. The methodology for determining tangible common equity may differ among companies. See "Non-GAAP Financial Measures" in Part I, Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Form 10-Q for additional information.

(4) The efficiency ratio is total noninterest expense as a percentage of total revenue (net interest income and noninterest income).

(5) The adjusted efficiency ratio, a non-GAAP financial measure, is adjusted noninterest expense (noninterest expense excluding costs associated with services provided to MUFG Bank, Ltd. branches in the U.S.) as a percentage of adjusted total revenue (net interest income and noninterest income excluding fees from affiliates for services provided to MUFG Bank, Ltd.'s branches in the U.S. and the impact of the TCJA). Management believes adjusting the efficiency ratio for the fees and costs associated with services provided to MUFG Bank, Ltd. branches in the U.S. enhances the comparability of MUAH's efficiency ratio when compared with other financial institutions. Management believes adjusting revenue for the impact of the TCJA enhances comparability between periods. See "Non-GAAP Financial Measures" in Part I, Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Form 10-Q for additional information.

(6) Yields, interest income and net interest margin are presented on a taxable-equivalent basis using the federal statutory tax rate of 21%.

(7) The allowance for loan losses ratios are calculated using the allowance for loan losses as a percentage of end of period total loans held for investment or total nonaccrual loans, as appropriate.

(8) The allowance for credit losses ratios include the allowances for loan losses and for losses on unfunded credit commitments as a percentage of end of period total loans held for investment or total nonaccrual loans, as appropriate.

(9) These capital ratios are calculated in accordance with the guidelines set forth in the U.S. federal banking agencies' final U.S. Basel III regulatory capital rules and all applicable amendments.

(10) The tangible common equity ratio, a non-GAAP financial measure, is calculated as tangible common equity divided by tangible assets. The methodology for determining tangible common equity may differ among companies. The tangible common equity ratio facilitates the understanding of the Company's capital structure and is used to assess and compare the quality and composition of the Company's capital structure to other financial institutions. See "Capital Management" in Part I, Item 2. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Form 10-Q for additional information.

Please refer to our Consolidated Financial Statements and the Notes to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 (2019 Form 10-K) along with the following discussion and analysis of our consolidated financial position and results of operations for the period ended March 31, 2020 in this Form 10-Q. Averages, as presented in the following tables, are substantially all based upon daily average balances.

As used in this Form 10-Q, terms such as the "Company,” “we,” “us” and “our” refer to MUFG Americas Holdings Corporation (MUAH), one or more of its consolidated subsidiaries, or to all of them together. As permitted by General Instruction H(2) of Form 10-Q, we have abbreviated Management's Discussion and Analysis into a management's narrative analysis of the results of operations.

Introduction

We are a financial holding company, bank holding company and intermediate holding company whose principal subsidiaries are MUFG Union Bank, N.A. (MUB or the Bank) and MUSA. We are owned by MUFG Bank, Ltd. and MUFG. MUFG Bank, Ltd. is a wholly-owned subsidiary of MUFG.

The Company has four reportable segments: Regional Bank, Global Corporate & Investment Banking - U.S., Transaction Banking and MUSA. We service Global Corporate & Investment Banking - U.S., certain Transaction Banking, and MUSA customers through the MUFG brand and serve Regional Bank and Transaction Banking customers through the Union Bank brand. We provide a wide range of financial services to consumers, small businesses, middle-market companies and major corporations, both nationally and internationally.

The Company also provides various business, banking, financial, administrative and support services, and facilities for MUFG Bank, Ltd. in connection with the operation and administration of MUFG Bank, Ltd.'s business in the U.S. (including MUFG Bank, Ltd.'s U.S. branches). The Bank and MUFG Bank, Ltd. are parties to a master services agreement whereby the Bank earns fee income in exchange for services and facilities provided.

The Company’s leadership team is bicoastal with Regional Bank and Transaction Banking leaders on the West Coast while Global Corporate & Investment Banking - U.S. and MUSA leaders are based in New York City. The corporate headquarters (principal executive office) for MUB, MUSA and MUAH is in New York City. MUB's main banking office is in San Francisco. The Company had consolidated assets of $165.7 billion at March 31, 2020.

Executive Overview

We are providing you with an overview of what we believe are the most significant factors and developments that affected our first quarter 2020 results and that could influence our future results. Further detailed information can be found elsewhere in this Form 10-Q. In addition, you should carefully read this entire document and any other reports that we refer to in this Form 10-Q for more detailed information to assist your understanding of trends, events and uncertainties that impact us.

Our sources of revenue are net interest income and noninterest income (collectively “total revenue”). Net interest income is generated predominantly from interest earned from loans, investment securities, securities borrowed or purchased under resale agreements, trading account assets and other interest-earning assets, less interest incurred on deposits and borrowings, securities loaned or sold under repurchase agreements and other interest-bearing liabilities. The primary sources of noninterest income are revenues from investment banking and syndication fees, service charges on deposit accounts, trust and investment management fees, trading account activities, credit facility fees, and fees from affiliates. Changes in interest rates, credit quality, economic trends and the capital markets are primary factors that affect our revenue sources. In the first quarter of 2020, revenue was comprised of 56% net interest income and 44% noninterest income. A summary of our financial results is discussed below.

Our primary sources of liquidity are core deposits, securities and wholesale funding. Core deposits exclude brokered deposits, foreign time deposits, domestic time deposits greater than $250,000, and certain other deposits not considered to be core customer relationships. Wholesale funding includes unsecured funds raised from MUFG Bank, Ltd. and affiliates, interbank and other sources, both domestic and international, funding secured by certain assets, or by borrowing from the FHLB. We evaluate and monitor the stability and reliability of our various funding sources to help ensure that we have sufficient liquidity when adverse situations arise.

10

In order to better serve our clients and reduce our cost base, we have launched two multi-year initiatives that we believe are critical to our success: our technology-focused Transformation Program and our continuous improvement, cost-reduction focused Rewiring Program. The Transformation Program is based on three pillars: transformation of our core banking systems, data analytics and functionality, and technology modernization. The Rewiring Program targets four areas: workforce geographic distribution, organizational design, procurement, and process simplification and automation.

Performance Highlights

Net loss attributable to MUAH was $306 million for the three months ended March 31, 2020, largely due to the provision for credit losses of $470 million. The provision for credit losses in the first quarter of 2020 was largely driven by the impact of COVID-19 and the corresponding deterioration in the economic environment. The global pandemic from the spread of COVID-19 has significantly impacted the U.S. and California economies and caused significant ongoing economic uncertainty, which may affect our critical accounting estimates, including our assumptions used to estimate the allowance for credit losses and used in our goodwill impairment analysis, and may adversely affect our business and results of operations in many other ways, the ultimate impact of which cannot be predicted at this time. See "Critical Accounting Estimates” in this Management's Discussion and Analysis of Financial Condition and Results of Operations and "Risk Factors" in Part II. Item 1A in this Form 10-Q.

On January 1, 2020, the Company adopted ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provides new guidance on the accounting for credit losses for instruments that are within its scope. This new guidance, commonly referred to as the CECL model, primarily impacts the Company's loans and certain off-balance sheet credit exposures and requires an entity to recognize its estimate of credit losses expected over the life of the financial instrument or exposure by incorporating forward-looking information, such as reasonable and supportable forecasts, in the entity's assessment of the collectability of financial assets. Incorporating forward-looking information into the estimate of credit losses may result in more volatility in the allowance for credit losses and related provision, particularly when the economic environment is more uncertain, such as during the first quarter of 2020. Upon adoption, the Company recorded an increase to the allowance for credit losses of $199 million, primarily due to an increase in the allowance for consumer loans. The Company elected to calculate its regulatory capital ratios using the CECL five-year transition option as prescribed by the U.S. regulatory banking agencies. See "Risk Management - Credit Risk Management" in this Management's Discussion and Analysis of Financial Condition and Results of Operations and Note 1 and Note 3 to our Consolidated Financial Statements in this Form 10-Q.

Capital Ratios

The Company's capital ratios continued to exceed all well-capitalized and minimum regulatory thresholds for BHCs, as applicable. The U.S. Basel III Common Equity Tier 1, Tier 1 and Total risk-based capital ratios were 13.88%, 13.88% and 14.79%, respectively, at March 31, 2020. The Tier 1 leverage ratio was 8.91% at March 31, 2020.

Net interest income for the three months endedMarch 31, 2020 decreased compared with the same period in 2019 due to a decline in the net interest margin partially offset by an increase in earning assets. The net interest margin decreased 4 basis points, primarily due to a decrease in yields on earning assets partially offset by a decrease in funding costs. Earning assets increased largely due to increases in interest bearing deposits in banks, and commercial and industrial and commercial mortgage loans, partially offset by decreases in securities and residential mortgage and home equity loans.

Noninterest Income and Noninterest Expense

Total noninterest income	$	612		$	632	$	(20	)	(3	)

Noninterest income decreased during the three months endedMarch 31, 2020 compared with the same period in 2019 primarily due to a decrease in trading account activities which included certain counterparty valuation adjustments, partially offset by increases in gains on sale of securities and fees from affiliates from services provided to MUFG Bank, Ltd. under the master services agreement. The decline in other, net was largely due to a decrease in the fair value of mortgage servicing rights. The Company uses derivatives to offset changes in the fair value of mortgage servicing rights. Changes in the fair value of these derivatives were included in trading account activities.

The increase in noninterest expense for the three months endedMarch 31, 2020 compared with 2019 was largely driven by impairment of a retail credit card intangible and increases in costs associated with services provided to MUFG Bank, Ltd. under the master services agreement.

Income Tax Expense

In the first quarter of 2020, income tax expense was $25 million and the effective tax rate was negative 9% due to excess tax credits that will be recognized during the year. In the first quarter of 2019, income tax expense was $28 million and the effective tax rate was 13%.

For additional information regarding income tax expense, see "Income Tax Expense" in Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations", “The changes in the U.S. tax laws, the majority of which were effective January 1, 2018, will impact our business and results of operations in a variety of ways, some of which are expected to be positive and others which may be negative” and “Our effective tax rates and our future results can also be affected by our participation for state income tax purposes as a member of MUFG’s unitary group in the U.S. and by other factors” in Part I, Item 1A.

Balance Sheet Analysis

Securities

Our securities portfolio is primarily used for liquidity and interest rate risk management purposes, to invest cash resulting from excess liquidity, and to a lesser extent, to support our business development objectives. We strive to maximize total return while managing this objective within appropriate risk parameters. Securities available for sale are substantially comprised of U.S. Treasury securities, U.S. government-sponsored agency securities, RMBSs, CMBSs, Cash Flow CLOs, and direct bank purchase bonds. Direct bank purchase bonds are instruments that are issued in bond form, accounted for as securities, but underwritten as loans with features that are typically found in commercial loans, and are subject to national bank regulatory lending authority standards. These instruments typically are not issued in bearer form, nor are they registered with the SEC or the Depository Trust Company. Additionally, these instruments generally contain certain transferability restrictions and are not assigned external credit ratings. Securities held to maturity consist of U.S. Treasury securities, U.S. government-sponsored agency securities and U.S. government-sponsored agency RMBSs and CMBSs.

The amortized cost, gross unrealized gains, gross unrealized losses and fair value of securities, and securities pledged as collateral, are detailed in Note 2 to our Consolidated Financial Statements in Part I, Item 1. "Financial Statements" in this Form 10-Q.

(1) Includes home equity loans of $2,006 million and $2,049 million at March 31, 2020 and December 31, 2019, respectively.

(2) Other consumer loans substantially include unsecured consumer loans and consumer credit cards.

Loans held for investment increased from December 31, 2019 to March 31, 2020, primarily due to growth in the commercial and industrial and construction portfolios, partially offset by a decrease in the residential mortgage and home equity and other consumer loan portfolios.

Deposits

The table below presents our deposits as of March 31, 2020 and December 31, 2019.

Total deposits	$	98,475	$	95,861	$	2,614		3

Total deposits increased $2.6 billion from December 31, 2019 to March 31, 2020 due largely to an increase in Transaction Banking noninterest bearing deposits and interest bearing transaction and money market accounts. This increase was partially offset by a decrease in Regional Bank time deposits, including PurePoint Financial, the direct banking division of the Bank.

Securities Financing Arrangements

The Company enters into securities purchased under agreements to resell, securities sold under agreements to repurchase, and securities borrowing and lending transactions to facilitate customer match-book activity, cover short positions and to fund the Company's trading inventory. These balances are almost entirely attributable to MUSA. See Note 5 "Securities Financing Arrangements" to our Consolidated Financial Statements in Part I, Item 1. "Financial Statements" in this Form 10-Q for additional information.

Capital Management

Both MUAH and MUB are subject to various capital adequacy regulations issued by the U.S. federal banking agencies, including requirements to complete an annual capital plan and to maintain minimum regulatory capital ratios. As of March 31, 2020, management believes the capital ratios of MUAH and MUB exceeded all regulatory requirements of “well-capitalized” institutions.

MUAH is subject to regulatory requirements to develop and maintain a capital plan which must be reviewed and approved by its Board of Directors (or designated subcommittee thereof). The Board of Directors approved the Company's annual capital plan in March 2020. Under the Tailoring Rules, MUAH, as a Category IV firm, is subject to CCAR supervisory capital planning requirements and stress testing submission requirements on an every other year basis in even years (e.g. MUAH is subject to the 2020 CCAR cycle). The Company timely filed its annual capital plan under the Federal Reserve's CCAR program in April 2020. See "Supervision and Regulation - Dodd-Frank Act and Related Regulations" and "Supervision and Regulation - Regulatory Capital and Liquidity Standards - Capital Planning and Comprehensive Capital Analysis and Review Program" in Part I, Item 1. "Business" of our 2019 Form 10-K.

MUAH and MUB are required to maintain minimum capital ratios under the standardized approach in accordance with the BCBS capital guidelines for U.S. banking organizations issued by the U.S. federal banking agencies (U.S. Basel III Rules). Among other requirements, the U.S. Basel III Rules require a minimum Common Equity Tier 1 capital ratio of 4.5% and a capital conservation buffer of 2.5% (for a total minimum Common Equity Tier 1 capital ratio of 7.0%) and a Tier 1 leverage ratio of 4.0%. For purposes of calculating its risk-based capital ratios, the Company has elected to phase-in the impact of adopting ASU 2016-13, Measurement of Credit Losses on Financial Instruments, over a five-year period as permitted by the U.S. regulatory banking agencies. The impact is reflected in the March 31, 2020 capital ratios presented below.

In addition to capital ratios determined in accordance with regulatory requirements, we consider the tangible common equity ratio when evaluating capital utilization and adequacy. This capital ratio is monitored by management, and presented below, to further facilitate the understanding of our capital structure and for use in assessing and comparing the quality and composition of the Company’s capital structure to other financial institutions. This ratio is not codified within GAAP or federal banking regulations in effect at March 31, 2020. Therefore, it is considered a non-GAAP financial measure. Our tangible common equity ratio calculation method may differ from those used by other financial services companies.

The following table summarizes the calculation of the Company's tangible common equity ratio as of March 31, 2020 and December 31, 2019.

Risk Management

All financial institutions must manage and control a variety of business risks that can significantly affect their financial condition and performance. Some of the key risks that the Company must manage include credit, market, liquidity, operational, interest rate, compliance, reputation and strategic risks. The Board, directly or through its appropriate committees, provides oversight and approves our various risk management policies. Management has established a risk management structure that is designed to provide a comprehensive approach for identifying, measuring, monitoring, controlling and reporting on the significant risks faced by the Company. For additional information regarding our risk management structure and framework, see “Risk Management” in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2019 Form 10-K. For additional information regarding risks related to our business, please refer to Part I, Item 1A. "Risk Factors" in our 2019 Form 10-K, and "Risk Factors" in Part II, Item 1A. in this Form 10-Q.

Credit Risk Management

One of our principal business activities is the extension of credit to individuals and businesses. Our policies and the applicable laws and regulations governing the extension of credit require risk analysis, including an extensive evaluation of the purpose of the request and the borrower’s ability and willingness to repay as scheduled. Our process also includes ongoing portfolio and credit management through portfolio diversification, lending limit constraints, credit review and approval policies, and extensive internal monitoring. For additional information regarding our credit risk management policies, see “Credit Risk Management” in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2019 Form 10-K.

Allowance for Credit Losses

Allowance Policy and Methodology

     We maintain an allowance for credit losses (defined as both the allowance for loan losses and the allowance for losses on unfunded credit commitments) to absorb expected losses on the loan portfolio as well as for unfunded credit commitments. On January 1, 2020, the Company adopted ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provided new guidance on the accounting for credit losses for instruments that are within its scope. This new guidance, commonly referred to as the CECL model, requires an entity to recognize its estimate of credit losses expected over the life of the financial instrument or exposure by incorporating forward-looking information in the entity's assessment of the collectability of financial assets. Accordingly, the Company's methodology for estimating the allowance balance uses relevant available information, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made over a forecast period to account for differences between current and expected future conditions and those reflected in historical loss information. Beyond the forecast period, estimated expected credit losses revert to historical loss experience.

Management establishes the allowance by first dividing its portfolio into two segments - the commercial segment and consumer segment. The allowance is measured on a collective basis when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated on an individual basis. While the Company's methodology attributes portions of the allowance to specific portfolio segments, the allowance estimate is provided to cover all credit losses expected in the loan portfolio.

An expected loss approach is used to estimate the collectively-assessed allowance for both the commercial and consumer portfolio segments. Expected loss is calculated as the product of PD, LGD, and EAD modeled parameters that are projected on a monthly basis over the assets’ remaining contractual lives. The sum of each month’s expected loss calculation results in the collectively-assessed allowance estimate. Expected loss models use historical loss information and economic assumptions to estimate PD, LGD, and EAD. These models are tailored to different loan segments, classes and products by changing the economic variables or their weighting in the calculation used to estimate expected losses.

The CECL adoption impact was estimated using a 36-month forecast period. The forecast period was shortened to 24-months in the first quarter of 2020 due to heightened volatility and uncertainty in the economy from the emergence of COVID-19. Beyond the economic forecast, the allowance methodology reverts to average historical loss experience on a straight-line basis over a 24-month period. These timeframes are regularly reviewed and approved by management and may be adjusted if economic conditions warrant. Expected prepayments are incorporated into the estimation of the EAD for each asset over the asset’s remaining term. Contractual term is not adjusted for expected extensions, renewals, and modifications unless we have a reasonable expectation that a TDR will be executed with a borrower.

Management implements qualitative adjustments to the collectively-assessed allowance to account for risks not incorporated in the model between current conditions and those reflected in the historical loss information used to estimate the models. These qualitative factors include changes in credit policies, problem loan trends, identification of new risks not incorporated into the modeling framework, credit concentrations, changes in lending management and other external factors. Qualitative adjustments are also used to adjust the collectively-assessed allowance to account for risks attributed to imprecision in the economic forecast and when risks emerge that impact specific portfolio components (i.e., natural disasters).

Loans that do not share risk characteristics are evaluated individually to determine the allowance balance. Loans assessed individually include larger nonaccruing loans within the commercial portfolio, TDRs, reasonably expected TDRs and collateral-dependent loans. The allowance for individually assessed loans is generally determined using either discounted cash flow analyses or collateral valuations to determine if loan carrying values exceed what the Company expects to collect.

For additional information on the allowance for loan losses and the allowance for credit losses, see "Critical Accounting Estimates" in this "Management's Discussion and Analysis of Financial Conditions and Results of Operations", Note 1 "Summary of Significant Accounting Policies and Nature of Operations" and Note 3 "Loans and Allowance for Loan Losses" to our Consolidated Financial Statements in this Form 10-Q.

Allowance and Related Provision for Credit Losses

The Company recorded an increase to the allowance for credit losses of $199 million upon the January 1, 2020 adoption of ASU 2016-13, Measurement of Credit Losses on Financial Instruments, primarily due to an increase in the allowance for consumer loans. This increase consisted of a $229 million increase in the allowance for loan losses and a $30 million decrease in the allowance for losses on unfunded credit commitments.

The provision for loan losses was $448 million for the three months endedMarch 31, 2020, largely due to the impact of COVID-19 and the corresponding deterioration in the economic environment on the collectively-assessed allowance for credit losses. The provision for loan losses was $274 million and $174 million for the commercial and consumer loan segments, respectively, largely due to economic deterioration observed late in the first quarter of 2020. Downgrades of several obligors also contributed to the increase in the commercial segment allowance. The economic forecast incorporated management's expectations at March 31, 2020, which included declining gross domestic product, unemployment approaching double digits by June 2020 and lower stock prices in 2020, with a modest recovery emerging in the fourth quarter of 2020 and continuing into subsequent years. The collectively-assessed allowance for credit losses estimate also incorporated management’s qualitatively-determined model adjustment overlays that reflect the anticipated loss mitigating impact of monetary and fiscal stimulus policies and loan modification programs, and additional qualitative adjustments largely driven by estimated impacts of COVID-19 that are not otherwise incorporated into the collectively-assessed modeling methodology.

The allowance for loan losses was $1,152 million at March 31, 2020, compared with $538 million at December 31, 2019. Our ratio of allowance for loan losses to total loans held for investment was 1.28% as of March 31, 2020 and 0.61% as of December 31, 2019. Net loans charged off to average total loans held for investment were 0.29% for the three months endedMarch 31, 2020, compared with 0.08% for the three months endedMarch 31, 2019.

Nonperforming Assets

Nonperforming assets consist of nonaccrual loans and OREO. Nonaccrual loans are those for which management has discontinued accrual of interest because there exists significant uncertainty as to the full and timely collection of either principal or interest, or such loans have become contractually past due 90 days with respect to principal or interest. OREO includes property where the Bank acquired title through foreclosure or “deed in lieu” of foreclosure. For a more detailed discussion of the accounting for nonaccrual loans, see Note 1 "Summary of Significant Accounting Policies and Nature of Operations" to our Consolidated Financial Statements in Part II, Item 8. “Financial Statements and Supplementary Data” in our 2019 Form 10-K.

The following table sets forth the components of nonperforming assets, TDRs, criticized assets and certain credit ratios.

The increase in criticized credits is primarily due to COVID-19 related downgrades in the aviation and transportation sectors. See Note 3 "Loans and Allowance for Loan Losses" to our Consolidated Financial Statements in Part I, Item 1. “Financial Statements” in this Form 10-Q for a description of criticized credits.

Troubled Debt Restructurings

TDRs are loans where we have granted a concession to a borrower as a result of the borrower experiencing financial difficulty and, consequently, we receive less than the current market-based compensation for loans with similar risk characteristics. Such loans are reviewed for impairment either individually or in pools with similar risk characteristics. Our loss mitigation strategies are designed to minimize economic loss and, at times, may result in changes to the original terms, including interest rate changes, maturity extensions, forbearance, principal paydowns, covenant waivers or changes, payment deferrals, or some combination thereof. We evaluate whether these changes to the terms and conditions of our loans meet the TDR criteria after considering the specific situation of the borrower and all relevant facts and circumstances related to the modification. For our consumer portfolio segment, TDRs are typically initially placed on nonaccrual and a minimum of six consecutive months of sustained performance is required before returning to accrual status. For our commercial portfolio segment, we generally determine accrual status for TDRs by performing an individual assessment of each loan, which may include, among other factors, borrower performance under previous loan terms.

The following table provides a summary of TDRs by loan type, including nonaccrual loans and loans that have been returned to accrual status, as of March 31, 2020 and December 31, 2019. See Note 3 "Loans and Allowance for Loan Losses" to our Consolidated Financial Statements in Part I, Item 1. “Financial Statements” in this Form 10-Q for additional information.

On March 22, 2020, the federal bank regulatory agencies issued joint guidance advising that the agencies have confirmed with the staff of the FASB that short-term modifications due to COVID-19 made on a good faith basis to borrowers who were current prior to relief, are not TDRs. On March 27, 2020 the CARES Act, which provides relief from TDR classification for certain COVID-19 related loan modifications, was signed into law. The Company is taking into consideration loan modification criteria under either the CARES Act or the criteria specified by the regulatory agencies when determining whether to suspend TDR accounting for such loan modifications.

Loans 90 Days or More Past Due and Still Accruing Interest

Loans held for investment 90 days or more past due and still accruing interest totaled $18 million and $20 million at March 31, 2020 and at December 31, 2019, respectively.

Concentration of Risk

Commercial and industrial loans are extended principally to corporations, middle-market businesses and small businesses and are originated primarily through our commercial banking offices. Our commercial and industrial portfolio is comprised primarily of the following industry sectors: finance and insurance, manufacturing, real estate and leasing, power and utilities, and wholesale trade. No individual industry sector exceeded 10% of our total loans held for investment at either March 31, 2020 or December 31, 2019.

Construction and commercial mortgage loans are secured by deeds of trust or mortgages. Construction loans are extended primarily to commercial property developers and to residential builders. At March 31, 2020, 85% of the Company’s construction loan portfolio was concentrated in California, 3% to borrowers in Oregon

24

and 3% to borrowers in Colorado. The commercial mortgage loan portfolio consists of loans secured by commercial income properties. At March 31, 2020, 64% of the Company’s commercial mortgage loans were made to borrowers located in California, 6% to borrowers in Washington, and 6% to borrowers in New York.

Residential mortgage loans are originated and secured by one-to-four family residential properties, through our multi-channel network, including branches, private bankers, mortgage brokers, telephone services, and web-based and mobile internet banking applications. We do not have a program for originating or purchasing subprime loan products and we hold the majority of the loans we originate.

At March 31, 2020, payment terms on 37% of our residential mortgage loans required a monthly payment that covers the full amount of interest due, but did not reduce the principal balance. At origination, these interest-only loans had strong credit profiles and had weighted average LTV ratios of approximately 64%. The remainder of the portfolio consisted of regularly amortizing loans.

Home equity loans are originated principally through our branch network and private banking offices. Approximately 24% of these home equity loans and lines were supported by first liens on residential properties as of both March 31, 2020 and December 31, 2019, respectively. To manage risk associated with lending commitments, we review all equity-secured lines annually for creditworthiness and may reduce or freeze limits, to the extent permitted by laws and regulations.

Other consumer loans substantially include unsecured consumer loans and consumer credit cards. The Company manages risk associated with these loans by establishing lending criteria similar to other consumer loans originated by the Company.

See Note 3 "Loans and Allowance for Loan Losses" to our Consolidated Financial Statements in Part I, Item 1. “Financial Statements” in this Form 10-Q for additional information on refreshed FICO scores for our consumer portfolio segment and refreshed LTV ratios for our residential mortgage and home equity loans at March 31, 2020 and December 31, 2019.

Market Risk Management

The objective of market risk management is to mitigate any adverse impact on earnings and capital arising from changes in interest rates and other market variables. Market risk management supports our broad objective of enhancing shareholder value, which encompasses the achievement of stable earnings growth while promoting capital stability over time. Market risk is defined as the risk of loss arising from an adverse change in the market value of financial instruments caused by fluctuations in market prices or rates. The primary market risk to which we are exposed is interest rate risk. Interest rate risk arises from instruments, positions and transactions entered into for purposes other than trading and for trading. Other than trading interest rate risk arises from loans, securities, deposits, borrowings, securities purchased under agreements to resell, securities sold under agreements to repurchase, securities borrowing and lending transactions, derivative instruments and mortgage servicing rights. Trading interest rate risk primarily arises from trading activities at MUAH's broker-dealer subsidiary, MUSA, and derivative contracts MUB enters into as a financial intermediary for customers.

LIBOR Transition

In July 2017, the Chief Executive of the U.K. Financial Conduct Authority, which regulates the process of setting LIBOR, announced that it intends to stop persuading or compelling banks to submit rates for the calculation of LIBOR after 2021. In the U.S., the Federal Reserve and Federal Reserve Bank of New York convened the Alternative Reference Rates Committee, a group of private-market participants, to help ensure a successful transition from USD LIBOR to a more robust reference rate. The Company recognizes that discontinuance of LIBOR, or any other IBOR-based rate, presents significant risks and challenges that could have an impact on its businesses globally (for information about the risks to the Company from the discontinuation of LIBOR or any other benchmark, see "The replacement of LIBOR could adversely impact our business and results of operations, and the value of certain financial instruments" in Part I, Item 1A. "Risk Factors" in our 2019 Form 10-K). We have exposure to IBORs, including in financial instruments and contracts that mature after 2021. Our exposures arise from business loans, derivatives, securities and other financial products (such as residential adjustable rate mortgages).

Accordingly, to facilitate an orderly transition from LIBOR and other benchmark rates to alternative reference rates, the Company has established a firm-wide transition program to identify, assess and monitor

25

risks associated with the expected discontinuation or unavailability of benchmarks, including LIBOR, develop and implement plans to remediate existing products or contracts that reference or rely upon IBORs, develop products and services that use alternative reference rates, achieve systems and operational readiness and engage impacted clients in connection with the transition to alternative reference rates. The Company’s transition program was established by senior management and periodically updates the Company's Board of Directors and ECA. The transition program focuses on:

• Identifying and evaluating the scope of existing financial instruments and contracts that may be affected;

• Assessing the impacted financial instruments and contracts to determine if they contain or require appropriate fallback language;

• Amending or otherwise developing action plans to amend existing financial instruments and contracts to incorporate robust fallback language;

• Enhancing infrastructure (e.g., internal framework such as models, technology infrastructure) to prepare for a smooth transition to alternative reference rates; and

• Developing financial instruments and contracts to use alternative reference rates.

The Company has identified the inherent risks with this transition and continues to monitor the development and usage of alternative reference rates. The Company is also working with regulators, industry working groups and trade associations to develop strategies for an effective transition to alternative reference rates. For additional information regarding our market risk management policies, see “Market Risk Management” in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2019 Form 10-K.

Liquidity Risk Management

Liquidity risk is the risk that an institution's financial condition or overall safety and soundness is adversely affected by an inability, or perceived inability, to meet its contractual, including contingent, obligations. The objective of liquidity risk management is to maintain a sufficient amount of liquidity and diversity of funding sources to allow an institution to meet obligations in both stable and adverse conditions.

The management of liquidity risk is governed by MUAH ALM and Liquidity Risk Management Policies. The MUAH ALM Policy is under the oversight of ALCO, which oversees first line liquidity risk management activities conducted by Treasury. Treasury formulates the funding, liquidity and contingency planning strategies for the Company, the Bank and MUSA, and is responsible for identifying, managing and reporting on liquidity risk. The Liquidity Risk Management Policies for the Company, the Bank and MUSA are under the oversight of the ARC and the Risk Committee of the Board. MRM conducts independent oversight and governance of liquidity risk management activities to establish sound policies and effective risk and independent monitoring controls. We are also subject to a Contingency Funding Plan framework that identifies actions to be taken to help ensure adequate liquidity if an event should occur that disrupts or adversely affects the normal funding activities of the Company, the Bank or MUSA.

Liquidity risk is managed using a total balance sheet perspective that analyzes all sources and uses of liquidity including loans, investments, deposits and borrowings, as well as off-balance sheet exposures. Although we make an effort to diversify our sources of liquidity, as discussed below, we are required to maintain a minimum amount of TLAC-eligible debt due to affiliates. Various tools are used to measure and monitor liquidity, including forecasting of the sources and uses of cash flows over multiple time horizons and stress testing of the forecasts under various scenarios. Stress testing, which incorporates both institution-specific, and systemic market scenarios, as well as a combination scenario that adversely affects the Company's liquidity position and profile, facilitates the identification of appropriate remedial measures to help ensure that the Company maintains adequate liquidity in adverse conditions. Such measures may include extending the maturity profile of liabilities, optimizing liability levels through pricing strategies, adding new funding sources, altering dependency on certain funding sources, adjusting asset growth and financing or selling assets.

We are subject to the Federal Reserve's rules imposing TLAC requirements on GSIBs with operations in the U.S., such as MUFG. These rules include an Internal TLAC requirement which sets a minimum amount of loss-absorbing instruments, which must be issued by the Company to MUFG or MUFG Bank, Ltd. (or another wholly-owned non-U.S. subsidiary of MUFG) due to MUFG's single point of entry resolution approach. These loss

26

absorbing instruments are comprised of Tier 1 regulatory capital and long-term debt. TLAC Tier 1 regulatory capital is designed to absorb ongoing losses, while the conversion of TLAC-eligible long-term debt into common equity of the Company is intended to recapitalize the Company prior to any bankruptcy or insolvency proceedings. See "Supervision and Regulation – Dodd-Frank Act and Related Regulations" in Part I, Item 1. "Business" in our 2019 Form 10-K for additional information.

We maintain a substantial level of available liquidity in the form of on-balance sheet and off-balance sheet funding sources. Sources of liquidity include cash at the Federal Reserve, unencumbered liquid securities, and capacity to borrow on a secured basis at the FHLB of San Francisco and the Federal Reserve Bank’s Discount Window. Total unpledged securities were $21.3 billion at March 31, 2020. Our primary funding sources are customer deposits, secured FHLB advances, and unsecured short-term and long-term debt. Total deposits increased $2.6 billion from $95.9 billion at December 31, 2019 to $98.5 billion at March 31, 2020. As of March 31, 2020, the Bank had $10.9 billion of borrowings outstanding with the FHLB of San Francisco, and the Bank had a remaining unused borrowing capacity from the FHLB of San Francisco of $20.6 billion. The Bank maintains a $12.0 billion unsecured bank note program. Available funding under the bank note program was $3.6 billion at March 31, 2020. We do not have any firm commitments in place to sell additional notes under this program.

In addition to managing liquidity risk on a consolidated basis and at each of the major subsidiaries (the Bank and MUSA), we assess and monitor liquidity at MUAH and other non-bank subsidiaries. MUAH maintains sufficient liquidity to meet expected obligations, without access to the wholesale funding markets or dividends from subsidiaries, for at least 18 months. At March 31, 2020, the parent company’s liquidity exceeded 18 months.

MUAH and its subsidiaries may borrow on a long-term basis from MUFG Bank, Ltd. and affiliates. As of March 31, 2020, the Company had total long-term debt issued to MUFG Bank, Ltd. and affiliates of $7.3 billion.

The Company’s total wholesale funding included $16.5 billion of long-term debt (excluding nonrecourse debt) and $5.6 billion of short-term debt at March 31, 2020. For additional information regarding our outstanding debt, see Note 6 "Commercial Paper and Other Short-Term Borrowings" and Note 7 "Long-Term Debt" to our Consolidated Financial Statements in Part I, Item 1. “Financial Statements” in this Form 10-Q. We evaluate and monitor the stability and reliability of our various funding sources to help ensure that we have sufficient liquidity in adverse circumstances.

27

Our costs and ability to raise funds in the capital markets are influenced by our credit ratings. In April 2020, Fitch placed the ratings of MUAH, MUB and MUSA on ratings watch negative as a result of Fitch’s downgrade of MUFG’s ratings to A-/F1 outlook stable from A/F1 outlook negative. This action follows Fitch’s recent revision of the U.S. Bank Sector Outlook and Rating Outlook, both to negative from stable, driven by concerns over the financial impact from COVID-19. On May 1, 2020, Fitch affirmed MUAH, MUB and MUSA's long and short-term ratings. The ratings watch negative was removed on the long-term rating and a negative outlook was assigned. The negative outlook reflects Fitch's view that there are significant operating environment challenges due to the disruption to economic activity and financial markets from the coronavirus pandemic. In April 2020, S&P revised the outlook on MUFG to stable from positive due to S&P’s expectation that economic strain from the COVID–19 pandemic will put prolonged pressure on asset quality and revenue lowering the likelihood of being upgraded. Subsequently, S&P revised MUAH, MUB, and MUSA’s outlook to stable from positive. The stable outlook reflects S&P’s expectation that MUAH will remain a core banking subsidiary of MUFG. Furthermore, any change in MUAH’s stand–alone credit profile will not affect MUAH's credit rating, which, S&P believes will remain closely tied to MUFG. The following table provides our credit ratings as of March 31, 2020.

		MUFG Union Bank, N.A.		MUFG Securities Americas Inc.	MUFG Americas Holdings Corporation
		Deposits	Senior Debt	Senior Debt	Senior Debt
S&P	Long-term	Not rated	A	A	A-
	Short-term	Not rated	A-1	A-1	A-2
Moody's	Long-term	Aa2	A2	Not rated	A2
	Short-term	P-1	P-1	Not rated	Not rated
Fitch	Long-term	A+	A	A	A
	Short-term	F1	F1	F1	F1

For additional information, including information about rating agency assessments, see “MUFG Bank Ltd.’s and Mitsubishi UFJ Financial Group’s credit ratings and financial or regulatory condition could adversely affect our operations” in Part I, Item 1A. "Risk Factors" in our 2019 Form 10-K and "Our credit ratings are important in order to maintain liquidity" in Part II, Item 1A. "Risk Factors" of this Form 10-Q.

Operational Risk Management

Operational risk is defined as the risk of loss resulting from inadequate or failed internal processes, people and systems or from external events. Operational risk includes legal risk, but excludes strategic and reputation risk. In particular, information security is a significant operational risk element for the Company and includes the risk of losses resulting from cyber-attacks or other related cyber incidents. See “We are subject to a wide array of operational risks, including, but not limited to, cyber-security risks” in Part I, Item 1A. “Risk Factors” in our 2019 Form 10-K. Operational risk is mitigated through a system of internal controls that are designed to keep these risks at appropriate levels. For additional information regarding our operational risk management policies, see “Operational Risk Management” in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2019 Form 10-K.

Critical Accounting Estimates

MUAH’s Consolidated Financial Statements are prepared in accordance with GAAP, which includes management estimates and judgments. The financial information contained within our statements is, to a significant extent, financial information that is based on estimates used to measure the financial effects of transactions and events. A variety of factors could affect the ultimate value that is obtained either when earning income, recognizing an expense, recovering an asset or relieving a liability. Significant estimates that we use include assumptions used in measuring PD, LGD and EAD to estimate expected credit losses, the assumptions used in measuring our transfer pricing revenue, assumptions used in evaluating our goodwill for impairment, and assumptions regarding our effective tax rates. Actual results could differ significantly from our estimates.

Management has reviewed and approved these critical accounting policies and has discussed these policies with the Audit & Finance Committee.

28

Allowance for Credit Losses

Our allowance for credit losses is an estimate of the credit losses that are expected over the life of the financial instrument or exposure and has three components: the allowance for loans measured on a collective basis, when similar risk characteristics exist, the allowance for loans measured on an individual basis, for loans that do not share similar risk characteristics, and the allowance for losses on unfunded credit commitments, which is included in other liabilities.

The Company's methodology for estimating credit losses uses relevant available information relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made over a forecast period to account for differences between current and expected future conditions and those reflected in historical loss information. Beyond the forecast period, estimated expected credit losses revert to average historical loss experience. To estimate the collectively-assessed allowance, expected loss is calculated as the product of PD, LGD, and EAD modeled parameters that are projected on a monthly basis over the assets’ remaining contractual lives.

Expected loss models incorporate significant assumptions over the forecast period based on management’s expectations. Estimating losses as of March 31, 2020 was particularly challenging due to the heightened volatility and uncertainty in the economy from the emergence of COVID-19. Significant management assumptions during the forecast period include GDP, unemployment, the duration of economic weakness, and the strength and timing of the following economic recovery. Management adjusted expected loss model calculations by incorporating qualitatively determined model adjustment overlays that reflect management’s expectations of the loss mitigating impact of monetary and fiscal stimulus policies and loan modification programs, and estimated impacts of COVID-19 not otherwise incorporated into the modeling methodology. The Company also shortened the forecast period to 24 months during the first quarter of 2020, compared with 36 months upon adoption of ASU 2016-13 as of January 1, 2020. Changes in these estimates could significantly impact our allowance and provision for credit losses.

For further information regarding our allowance for loan losses, see "Risk Management - Credit Risk Management - Allowance for Credit Losses" in this Management's Discussion and Analysis of Financial Condition and Results of Operations, "Allowance for Loan Losses" in Note 1 and Note 3 to our Consolidated Financial Statements in this Form 10-Q.

Goodwill Impairment

We allocate our goodwill to reporting units and review for impairment at least annually, and whenever events or changes in circumstances indicate the carrying amount may not be recoverable. Goodwill is assessed for impairment at the reporting unit level either qualitatively or quantitatively. If the elected qualitative assessment results indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative impairment test is required. Various valuation methodologies are applied to carry out the quantitative impairment test by comparing the fair value of the reporting unit to its carrying amount, including goodwill.

Management applies significant judgment when estimating the fair value of its reporting units. This judgment includes developing cash flow projections, selecting appropriate discount rates, incorporating general economic and market conditions, identifying relevant market comparables, and selecting an appropriate control premium. Imprecision in estimating these factors can affect the estimated fair value of the reporting units.

The Company continuously monitors inputs used when performing its annual goodwill impairment analysis such as the cash flow projections developed to estimate the fair value of its reporting units. When a disruption in the Company’s business, unexpected significant declines in operating results, or significant trends become apparent that may negatively affect those projections, the Company may have to assess the need to perform the quantitative impairment test to conclude whether the fair value of the reporting unit is still above its carrying amount. Subsequent to the first quarter of 2020, the Company completed its annual goodwill impairment test as of April 1, 2020 and concluded its goodwill was not impaired. However, the Company's Commercial Banking and Real Estate Industries and Global Corporate & Investment Banking - U.S. reporting units' estimated fair values did not significantly exceed their carrying amounts.

Understanding our accounting policies is fundamental to understanding our consolidated financial condition and consolidated results of operations. Accordingly, both our critical accounting estimates and our

29

significant accounting policies are discussed in detail in our 2019 Form 10-K. There were no material changes to our transfer pricing, goodwill impairment analysis, or income taxes critical accounting estimates during the first quarter of 2020.

Non-GAAP Financial Measures

The following table presents a reconciliation between certain GAAP amounts and specific non-GAAP measures used to calculate return on average MUAH tangible common equity for the three months endedMarch 31, 2020 and 2019. Management believes that this ratio provides useful supplemental information regarding the Company's business results.

	For the Three Months Ended
(Dollars in millions)	March 31, 2020			March 31, 2019
Net (loss) income attributable to MUAH	$	(306	)	$	184
Add: Intangible asset amortization, net of tax	5			5
Net (loss) income attributable to MUAH, excluding intangible asset amortization (a)	$	(301	)	$	189
Average MUAH stockholders' equity	$	16,508		$	16,717
Less: Goodwill	1,764			3,367
Less: Intangible assets, except mortgage servicing rights	258			295
Less: Deferred tax liabilities related to goodwill and intangible assets	(18		)	(60		)
Average MUAH tangible common equity (b)	$	14,504		$	13,115
Return on average MUAH tangible common equity (1) (a)/(b)	(8.30		)%	5.76		%

(1)     Annualized.

The following table shows the calculation of the adjusted efficiency ratio for the three months endedMarch 31, 2020 and 2019. Management believes adjusting the efficiency ratio for the fees and costs associated with services provided to MUFG Bank, Ltd. branches in the U.S. enhances the comparability of MUAH's efficiency ratio when compared with other financial institutions.

	For the Three Months Ended
(Dollars in millions)	March 31, 2020			March 31, 2019
Noninterest expense (a)	$	1,201		$	1,170
Less: Costs associated with services provided to MUFG Bank, Ltd. branches in the U.S.	319			310
Noninterest expense, as adjusted (b)	$	882		$	860
Total revenue (c)	$	1,386		$	1,415
Less: Fees from affiliates for services provided to MUFG Bank, Ltd.'s branches in the U.S.	339			326
Total revenue, as adjusted (d)	$	1,047		$	1,089
Efficiency ratio (a)/(c)	86.65		%	82.67		%
Adjusted efficiency ratio (b)/(d)	84.23		%	78.96		%

Disclosure of Iranian Activities under Section 13(r) of the Securities Exchange Act of 1934

We are disclosing the following information pursuant to Section 13(r) of the Exchange Act which requires an issuer to disclose whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with natural persons or entities designated by the U.S. government under specified Executive Orders. The scope of activities that must be reported includes activities not prohibited by U.S. law and conducted outside the United States in compliance with applicable local law. Because we are indirectly wholly-owned by MUFG, a Japanese corporation, our disclosure is required to include, in addition to our activities, transactions or dealings, those conducted outside the United States by non-U.S. affiliates of MUFG which are

30

not controlled by us. We have requested that MUFG provide us a description of reportable activity under Section 13(r) and have received the following information:

During the quarter ended March 31, 2020, MUFG's non-U.S. subsidiary, MUFG Bank, engaged in certain limited business activities with entities in, or affiliated with, Iran, including counterparties owned or controlled by the Iranian government. During this period, MUFG Bank handled several remittances in connection with exports from Japan to Iran by its Japanese customers in 2019. These remittance services did not involve U.S. dollars or clearing services of U.S. banks. For the quarter ended March 31, 2020, the aggregate fee income relating to these transactions was less than ¥5 million, representing less than 0.001 percent of MUFG’s total fee income. In addition, some Iranian financial institutions and other entities in, or affiliated with, Iran maintained non-U.S. dollar correspondent accounts and other similar settlement accounts with MUFG Bank outside the United States. In addition to such accounts, MUFG Bank received deposits in Japan from, and provided settlement services in Japan to, fewer than 10 Iranian government-related entities and fewer than 100 Iranian government-related individuals such as Iranian diplomats, and maintains settlement accounts outside the United States for certain other financial institutions specified in Executive Order 13382, which settlement accounts were frozen in accordance with applicable laws and regulations. For the quarter ended March 31, 2020, the average aggregate balance of deposits held in these accounts represented less than 0.1 percent of the average balance of MUFG’s total deposits. The fee income from the transactions attributable to these account holders was less than ¥1 million, representing less than 0.001 percent of MUFG’s total fee income.

We understand that MUFG Bank recognizes that following the withdrawal in May 2018 by the United States from the Joint Comprehensive Plan of Action, the United States has imposed secondary sanctions against non-U.S. persons who engage in or facilitate a broad range of transactions and activities involving Iran.

Notes to Consolidated Financial Statements

Note 1—Summary of Significant Accounting Policies and Nature of Operations

MUFG Americas Holdings Corporation (MUAH) is a financial holding company, bank holding company and intermediate holding company whose principal subsidiaries are MUFG Union Bank, N.A. (MUB or the Bank) and MUFG Securities Americas Inc. (MUSA). MUAH provides a wide range of financial services to consumers, small businesses, middle-market companies and major corporations nationally and internationally. The Company also provides various business, banking, financial, administrative and support services, and facilities for MUFG Bank, Ltd. (formerly The Bank of Tokyo-Mitsubishi UFJ, Ltd.) in connection with the operation and administration of MUFG Bank, Ltd.'s business in the U.S. (including MUFG Bank, Ltd.'s U.S. branches). All of the Company's issued and outstanding shares of common stock are owned by MUFG Bank, Ltd. and MUFG. The unaudited Consolidated Financial Statements of MUFG Americas Holdings Corporation, its subsidiaries, and its consolidated variable interest entities (the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Rules and Regulations of the SEC. However, they do not include all of the disclosures necessary for annual financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the first quarter of 2020 are not necessarily indicative of the operating results anticipated for the full year. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 (2019 Form 10-K).

The preparation of financial statements in conformity with GAAP also requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Although such estimates contemplate current conditions and management’s expectations of how they may change in the future, it is reasonably possible that actual results could differ significantly from those estimates. This could materially affect the Company’s results of operations and financial condition in the near term. Critical estimates made by management in the preparation of the Company’s financial statements include, but are not limited to, the allowance for credit losses (Note 3 "Loans and Allowance for Loan Losses"), goodwill impairment, fair value of financial instruments (Note 8 "Fair Value Measurement and Fair Value of Financial Instruments"), pension accounting (Note 11 "Employee Pension and Other Postretirement Benefits"), income taxes, and transfer pricing.

Allowance for Credit Losses

Allowance for loan losses

Allowance for loan losses is a valuation account that is deducted from the assets’ amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off.

Management develops and documents its systematic methodology for determining the allowance by

first dividing its portfolio into two segments - the commercial segment and consumer segment. The Company

further divides its portfolio segments into classes based on initial measurement attributes, risk characteristics or its method of monitoring and assessing credit risk. The classes for the Company include commercial and industrial, commercial mortgage, construction, residential mortgage and home equity, and other consumer loans. While the Company's methodology attributes portions of the allowance to specific portfolio segments and classes, the allowance estimate is provided to cover all credit losses expected in the loan portfolio.

The Company's methodology for estimating the allowance balance uses relevant available information, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made to account for differences between current and expected future conditions and those reflected in historical loss information. The allowance is measured on a collective basis when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated on an individual basis.

37

Note 1—Summary of Significant Accounting Policies and Nature of Operations (Continued)

The collectively-assessed allowance methodology incorporated an economic forecast over a 36-month period when ASU 2016-13, Measurement of Credit Losses on Financial Instruments, was adopted as of January 1, 2020. Beyond the 36-month economic forecast, the allowance methodology reverted to average historical loss information on a straight-line basis over a 24-month period. However, the economic forecast was shortened to a 24-month period during the first quarter of 2020 due to heightened volatility and uncertainty in the economy due to the emergence of COVID-19. No change was made to the 24-month straight-line reversion to historical loss information. These timeframes are regularly reviewed and approved by management and may be adjusted if economic conditions warrant.

An expected loss approach is used to estimate the collectively-assessed allowance for both the commercial and consumer portfolio segments. Expected loss is calculated as the product of PD, LGD, and EAD modeled parameters that are projected on a monthly basis over the assets’ remaining contractual lives. The sum of each month’s expected loss calculation results in the collectively-assessed allowance estimate. Expected loss models use historical loss information and a variety of economic assumptions to estimate PD, LGD, and EAD. These models are tailored to different loan segments, classes and products by changing the economic variables or their weighting in the calculation used to estimate expected losses.

The allowance is an estimate of expected credit losses over the remaining contractual term of each

asset. Expected prepayments are incorporated into the estimation of the EAD for each asset over the asset’s remaining term, which shortens the expected remaining term. Contractual term is not adjusted for expected extensions, renewals, and modifications unless we have a reasonable expectation that a TDR will be executed with a borrower. Credit cards do not have defined contractual terms. In order to estimate the expected credit losses on actively used revolving credit card balances, we make assumptions about expected payments and expected spending on the unconditionally cancelable unfunded amount at the measurement date. Expected spending after the measurement date reduces the expected payments that are allocated to the outstanding balance at the measurement date. Expected credit losses are calculated only on the outstanding balances component at the measurement date, which is amortized by applying the proportion of the expected payment allocated to the outstanding balance. Expected payments applied to the expected spending after the measurement date are effectively excluded from the analysis because unconditionally cancelable unfunded commitments are not reservable.

Loans that do not share risk characteristics are evaluated individually to determine the allowance balance. Loans assessed individually include larger nonaccruing loans within the commercial portfolio, TDRs, reasonably expected TDRs and collateral-dependent loans. Collateral-dependent loans are generally individually-assessed for allowance purposes. Collateral-dependent assets' expected credit losses are assessed when the fair value of the collateral is less than the amortized cost basis of the asset. Collateral-dependent assets are evaluated in this manner when foreclosure is probable, or when repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. Estimated costs to sell are included in the estimate when repayment is expected by the sale of the collateral. Collateral-dependent assets are generally secured by real estate collateral. When the discounted cash flow method is used to determine the allowance for individually-assessed loans, management does not adjust the interest rate used to discount expected cash flows to incorporate expected prepayments.

Management implements qualitative adjustments to the collectively-assessed allowance to account for the risks not incorporated in the model between current conditions and those reflected in the historical loss information used to estimate the models. These qualitative factors include changes in credit policies, problem loan trends, identification of new risks not incorporated into the modeling framework, credit concentrations, changes in lending management and other external factors. Qualitative adjustments are also used to adjust the collectively-assessed allowance to account for risks attributed to imprecision in the economic forecast and when risks emerge that impact specific portfolio components (i.e., natural disasters).

TDRs are loans where we have granted a concession to a borrower as a result of the borrower experiencing financial difficulty and, consequently, we receive less than the current market-based compensation for loans with similar risk characteristics. Such loans' allowance is measured either individually or in pools with similar risk characteristics. The allowance for a TDR loan is measured using the same method as all other loans when evaluated in pools. The allowance for individually assessed TDR loans can be measured using a discounted cash flow methodology, or by evaluating the fair value of the collateral, if collateral dependent. When the value

38

Note 1—Summary of Significant Accounting Policies and Nature of Operations (Continued)

of a concession cannot be measured using a method other than the discounted cash flow method, the value of a concession is measured by discounting the expected future cash flows at the original interest rate of the loan. When we have a reasonable expectation that a TDR loan may be executed with a borrower at the evaluation date, we may modify the allowance calculation to align with the expected modification terms, which may include modifying the expected contractual term.

We do not record an allowance for accrued interest receivable on loans held for investment, which is included in other assets on the consolidated balance sheet. Uncollectible accrued interest is reversed through interest income.

Allowance for Credit Losses on Debt Securities

All securities held to maturity are explicitly or implicitly guaranteed by U.S. government entities or agencies and have a long history of no credit losses. No credit losses are expected on these assets and thus no allowance is estimated on securities held to maturity.

Securities available for sale are composed of assets that are explicitly or implicitly guaranteed by U.S. government entities or agencies and non-agency-backed assets that are highly rated and have not incurred credit losses historically. Unrealized losses on available for sale securities arise from changes in market conditions, not credit losses. Direct purchase bonds are not externally rated but are assessed quarterly to determine whether credit losses exist. Unrealized losses on the direct purchase bonds have arisen from higher current expected returns on capital as compared with required rates of return on capital on the bonds at origination. No credit losses are expected on these assets and thus no allowance is estimated on securities available for sale.

Allowance for Credit Losses on Securities Borrowed or Purchased under Resale Agreements

Securities borrowed or purchased under resale agreements are also subject to allowance estimation, however management has no history of credit losses on these assets and has portfolio monitoring practices that ensure collateral is maintained at appropriate levels. As borrowers have a history of replenishing collateral securing the financial assets, when needed, and are expected to continue to maintain such behavior in the future, no allowance is estimated on these assets, consistent with the practical expedient methodology described in ASC 326-20-35-6. Management reviews these portfolios on a quarterly basis to confirm the conclusion of no allowance for credit losses remains appropriate.

Allowance for Credit Losses on Unfunded Credit Commitments

The Company maintains an allowance for losses on unfunded credit commitments for the contractual term over which we are exposed to credit risk that is not unconditionally cancelable by the Company. The Company's allowance methodology for unfunded credit commitments is the same as that used for the allowance for the other collectively-evaluated assets and includes an estimate of commitments that are expected to fund over the remaining contractual term. The allowance for losses on unfunded credit commitments is classified as other liabilities on the balance sheet, with the changes recognized in the provision for credit losses.

Recently Adopted Accounting Pronouncements

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provides new guidance on the accounting for credit losses for instruments that are within its scope. This new guidance is commonly referred to as the CECL model. For loans and debt securities accounted for at amortized cost, certain off-balance sheet credit exposures, net investments in leases, and trade receivables, the ASU requires an entity to recognize its estimate of credit losses expected over the life of the financial instrument or exposure by incorporating forward-looking information, such as reasonable and supportable forecasts, in the entity's assessment of the collectability of financial assets. Lifetime expected credit losses on purchased financial assets with credit deterioration will be recognized as an allowance with an offset to the cost basis of the asset. For available for sale debt securities, the new standard will require recognition of expected credit losses by recognizing

39

Note 1—Summary of Significant Accounting Policies and Nature of Operations (Continued)

an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. The Company adopted the ASU on January 1, 2020, and recorded an increase to the allowance for credit losses of $199 million, primarily due to an increase in the allowance for consumer loans, offset by a $52 million deferred tax asset, and a $147 million cumulative-effect adjustment reduction to retained earnings.

Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies disclosure requirements on fair value measurements to improve their effectiveness. The guidance permits entities to consider materiality when evaluating fair value measurement disclosures and, among other modifications, requires certain new disclosures related to Level 3 fair value measurements. The Company adopted the ASU on January 1, 2020. The guidance only affects disclosures in the Notes to the Consolidated Financial Statements and will not affect the Company’s financial position or results of operations.

At March 31, 2020, the Company did not have the intent to sell any securities in an unrealized loss position before a recovery of the amortized cost, which may be at maturity. The Company also believes that it is more likely than not that it will not be required to sell the securities prior to recovery of amortized cost.

Agency residential and commercial mortgage-backed securities consist of securities guaranteed by a U.S. government corporation, such as Ginnie Mae, or a government-sponsored agency such as Freddie Mac or Fannie Mae. These securities are collateralized by residential and commercial mortgage loans and may be prepaid at par prior to maturity. The unrealized losses on agency residential mortgage-backed securities resulted from changes in interest rates and not from changes in credit quality. At March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities because the Company determined that the strength of the issuers’ guarantees through direct obligations or support from the U.S. government is sufficient to protect the Company from losses.

Commercial mortgage-backed securities are collateralized by commercial mortgage loans and are generally subject to prepayment penalties. The unrealized losses on commercial mortgage-backed securities resulted from higher market yields since purchase. Cash flow analysis of the underlying collateral provides an estimate of impairment, which is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities.

The Company’s CLOs consist of Cash Flow CLOs. A Cash Flow CLO is a structured finance product that securitizes a diversified pool of loan assets into multiple classes of notes. Cash Flow CLOs pay the note holders through the receipt of interest and principal repayments from the underlying loans unlike other types of CLOs that pay note holders through the trading and sale of underlying collateral. Unrealized losses typically arise from widening credit spreads and deteriorating credit quality of the underlying collateral. Cash flow analysis of the underlying collateral provides an estimate of impairment, which is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities.

Direct bank purchase bonds are not rated by external credit rating agencies. The unrealized losses on these bonds resulted from a higher return on capital expected by the secondary market compared with the return on capital required at the time of origination when the bonds were purchased. The Company estimates the unrealized loss for each security by assessing the underlying collateral of each security. The Company estimates the portion of loss attributable to credit based on the expected cash flows of the underlying collateral using estimates of current key assumptions, such as probability of default and loss severity. Cash flow analysis of the underlying collateral provides an estimate of impairment, which is performed quarterly when the fair value of a security is lower than its amortized cost and potential impairment is identified. Based on the analysis performed as of March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities.

Note 2—Securities (Continued)

Amortized cost is defined as the original purchase cost, adjusted for any accretion or amortization of a purchase discount or premium, less principal payments and any impairment previously recognized in earnings. The carrying amount is the difference between the amortized cost and the amount recognized in OCI. The amount recognized in OCI primarily reflects the unrealized gain or loss at date of transfer from available for sale to the held to maturity classification, net of amortization, which is recorded in interest income on securities.

The Company’s securities held to maturity with a continuous unrealized loss position at March 31, 2020 and December 31, 2019 are shown below, separately for periods less than 12 months and 12 months or more.

Note 3—Loans and Allowance for Loan Losses (Continued)

Allowance for Loan Losses

The provision for loan losses was $448 million for the three months endedMarch 31, 2020, largely due to the impact of COVID-19 and the corresponding deterioration in the economic environment on the collectively-assessed allowance for credit losses. The provision for loan losses was $274 million and $174 million for the commercial and consumer loan segments, respectively, largely due to economic deterioration observed late in the first quarter of 2020. Downgrades of several obligors also contributed to the commercial segment provision. The economic forecast incorporated management's expectations at March 31, 2020, which included declining gross domestic product, unemployment approaching double digits by June 2020 and lower stock prices in 2020, with a modest recovery emerging in the fourth quarter of 2020 and continuing into subsequent years. The collectively-assessed allowance for credit losses estimate also incorporated management’s qualitatively-determined model adjustment overlays that reflect the anticipated loss mitigating impact of monetary and fiscal stimulus policies and loan modification programs, and additional qualitative adjustments largely driven by estimated impacts of COVID-19 that are not otherwise incorporated into the collectively-assessed modeling methodology. The following tables provide a reconciliation of changes in the allowance for loan losses by portfolio segment.

Credit Quality Indicators

Management analyzes the Company's loan portfolios by applying specific monitoring policies and procedures that vary according to the relative risk profile and other characteristics within the various loan portfolios. Loans within the commercial portfolio segment are classified as either pass or criticized. Criticized credits are those that have regulatory risk ratings of special mention, substandard or doubtful; classified credits are those that have regulatory risk ratings of substandard or doubtful. Special mention credits are potentially weak, as the borrower has begun to exhibit deteriorating trends, which, if not corrected, may jeopardize repayment of the loan and result in further downgrade. Substandard credits have well-defined weaknesses, which, if not corrected, could jeopardize the full satisfaction of the debt. A credit classified as doubtful has critical weaknesses that make full collection improbable on the basis of currently existing facts and conditions.

Note 3—Loans and Allowance for Loan Losses (Continued)

The Company also monitors the credit quality for substantially all of its consumer portfolio segment using credit scores provided by FICO and refreshed LTV ratios. FICO credit scores are refreshed at least quarterly to monitor the quality of the portfolio. Refreshed LTV measures the principal balance of the loan as a percentage of the estimated current value of the property securing the loan. Home equity loans are evaluated using combined LTV, which measures the principal balance of the combined loans that have liens against the property (including unused credit lines for home equity products) as a percentage of the estimated current value of the property securing the loans. The LTV ratios are refreshed on a quarterly basis, using the most recent home pricing index data available for the property location. 

The following tables summarize the loans in the consumer portfolio segment based on refreshed FICO scores and refreshed LTV ratios at March 31, 2020 and December 31, 2019. The December 31, 2019 amounts presented reflect unpaid principal balances less partial charge-offs.

Troubled Debt Restructurings

The following table provides a summary of the Company’s recorded investment in TDRs as of March 31, 2020 and December 31, 2019. The summary includes those TDRs that are on nonaccrual status and those that continue to accrue interest. The Company had $33 million and $61 million in commitments to lend additional funds to borrowers with loan modifications classified as TDRs as of March 31, 2020 and December 31, 2019, respectively.

Residential mortgage and home equity	186		192
Other consumer	1		1
Total consumer portfolio	187		193
Total restructured loans	$	476	$	563

For the first quarter of 2020, TDR modifications in the commercial portfolio segment were substantially composed of maturity extensions and conversions of revolving lines of credit into fixed terms. In the consumer portfolio segment, modifications were largely composed of maturity extensions and interest rate reductions. There were no charge-offs related to TDR modifications for the three months ended March 31, 2020 and March 31, 2019. For the commercial and consumer portfolio segments, the allowance for loan losses for TDRs was measured on an individual loan basis or in pools with similar risk characteristics.

Note 3—Loans and Allowance for Loan Losses (Continued)

The following tables provide the pre- and post-modification outstanding recorded investment amounts of TDRs as of the date of the restructuring that occurred during the three months ended March 31, 2020 and 2019.

(2) Represents the recorded investment in the loan immediately following the restructuring event. It includes the effect of paydowns that were required as part of the restructuring terms.

The recorded investment amounts of TDRs at the date of default, for which there was a payment default during the three months ended March 31, 2020 and 2019, and where the default occurred within the first twelve months after modification into a TDR were de minimis. A payment default is defined as the loan being 60 days or more past due.

For loans in the consumer portfolio in which allowance for loan losses is measured using the present value of expected future cash flows discounted at the loan’s effective interest rate, historical payment defaults and the propensity to redefault are some of the factors considered when determining the allowance for loan losses.

On March 22, 2020, the federal bank regulatory agencies issued joint guidance advising that the agencies have confirmed with the staff of the FASB that short-term modifications due to COVID-19 made on a good faith basis to borrowers who were current prior to relief, are not TDRs. On March 27, 2020 the CARES Act, which provides relief from TDR classification for certain COVID-19 related loan modifications, was signed into law. For COVID-19 related loan modifications which occurred from March 1, 2020, through March 31, 2020, and met the loan modification criteria under either the CARES Act or the criteria specified by the regulatory agencies, we elected to suspend TDR accounting for such loan modifications.

Note 4—Variable Interest Entities

In the normal course of business, the Company has certain financial interests in entities which have been determined to be VIEs. Generally, a VIE is a corporation, partnership, trust or other legal structure where the equity investors do not have substantive voting rights, an obligation to absorb the entity’s losses or the right to receive the entity’s returns, or the ability to direct the significant activities of the entity. The following discusses the Company’s consolidated and unconsolidated VIEs.

Consolidated VIEs

The following tables present the assets and liabilities of consolidated VIEs recorded on the Company’s consolidated balance sheets at March 31, 2020 and December 31, 2019.

	March 31, 2020

Total consolidated VIEs		$	349	$	213	$	562	$	45	$	45

LIHC Investments

The Company sponsors, manages and syndicates two LIHC investment fund structures. These investments are designed to generate a return primarily through the realization of U.S. federal tax credits and deductions. The Company is considered the primary beneficiary and has consolidated these investments because the Company has the power to direct activities that most significantly impact the funds’ economic performances and also has the obligation to absorb losses of the funds that could potentially be significant to the funds. Neither creditors nor equity investors in the LIHC investments have any recourse to the general credit of the Company, and the Company’s creditors do not have any recourse to the assets of the consolidated LIHC investments.

Leasing Investments

The Company has leasing investments primarily in the wind energy, rail and coal industries. The Company is considered the primary beneficiary and has consolidated these investments because the Company has the power to direct the activities of these entities that significantly impact the entities’ economic performances. The Company also has the right to receive potentially significant benefits or the obligation to absorb potentially significant losses of these investments.

Unconsolidated VIEs

The following tables present the Company’s carrying amounts related to the unconsolidated VIEs at March 31, 2020 and December 31, 2019. The tables also present the Company’s maximum exposure to loss resulting from its involvement with these VIEs. The maximum exposure to loss represents the carrying amount of the Company’s involvement plus any legally binding unfunded commitments in the unlikely event that all of the assets in the VIEs become worthless. During the three months endedMarch 31, 2020 and March 31, 2019, the Company had noncash increases in unfunded commitments on LIHC investments of $52 million and $55 million, respectively, included within other liabilities.

LIHC Investments

The Company makes investments in partnerships and funds formed by third parties. The primary purpose of the partnerships and funds is to invest in low-income housing units and distribute tax credits and tax benefits associated with the underlying properties to investors. The Company is a limited partner investor and is allocated tax credits and deductions, but has no voting or other rights to direct the activities of the funds or partnerships, and therefore is not considered the primary beneficiary and does not consolidate these investments.

The following table presents the impact of the unconsolidated LIHC investments on our consolidated statements of income for the three months endedMarch 31, 2020 and 2019.

Note 4—Variable Interest Entities (Continued)

Renewable Energy Investments

Through its subsidiaries, the Company makes equity investments in LLCs established by third party sponsors to operate and manage wind, solar, hydroelectric and cogeneration power plant projects. Power generated by the projects is sold to third parties through long-term purchase power agreements. As a limited investor member, the Company is allocated production tax credits and taxable income or losses associated with the projects. The Company has no voting or other rights to direct the significant activities of the LLCs, and therefore is not considered the primary beneficiary and does not consolidate these investments.

Other Investments

The Company has other investments in structures formed by third parties. The Company has no voting or other rights to direct the activities of the investments that would most significantly impact the entities’ performance, and therefore is not considered the primary beneficiary and does not consolidate these investments.

Note 5—Securities Financing Arrangements

The Company enters into repurchase agreements and securities lending agreements to facilitate customer match-book activity, cover short positions and fund the Company's trading inventory. The Company manages credit exposure from certain transactions by entering into master netting agreements and collateral arrangements with counterparties. The relevant agreements allow for the efficient closeout of the transaction, liquidation and set-off of collateral against the net amount owed by the counterparty following a default. Under these agreements and transactions, the Company either receives or provides collateral in the form of securities. In many cases, the Company is permitted to sell or repledge these securities held as collateral and use the securities to secure repurchase agreements or enter into securities lending transactions. In certain cases, the Company may agree for collateral to be posted to a third party custodian under a tri-party arrangement that enables the Company to take control of such collateral in the event of a counterparty default. Default events generally include, among other things, failure to pay, insolvency or bankruptcy of a counterparty. For additional information related to securities pledged and received as collateral, refer to Note 2 "Securities" to these Consolidated Financial Statements.

The following table presents the gross obligations for securities sold under agreements to repurchase and securities loaned by remaining contractual maturity and class of collateral pledged as of March 31, 2020 and December 31, 2019.

Offsetting Financial Assets and Liabilities

The Company primarily enters into derivative contracts, repurchase agreements and securities lending agreements with counterparties utilizing standard International Swaps and Derivatives Association Master Agreements and Credit Support Annex Agreements, Master Repurchase Agreements, and Master Securities Lending Agreements, respectively. These agreements generally establish the terms and conditions of the transactions, including a legal right to set-off amounts payable and receivable between the Company and a counterparty, regardless of whether or not such amounts have matured or have contingency features.

The following tables present the offsetting of financial assets and liabilities as of March 31, 2020 and December 31, 2019.

Note 8—Fair Value Measurement and Fair Value of Financial Instruments

Valuation Methodologies

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., an exit price) in an orderly transaction between willing market participants at the measurement date. The Company has an established and documented process for determining fair value for financial assets and liabilities that are measured at fair value on either a recurring or nonrecurring basis. When available, quoted market prices are used to determine fair value. If quoted market prices are not available, fair value is based upon valuation techniques that use, where possible, current market-based or independently sourced parameters, such as yield curves, foreign exchange rates, credit spreads, commodity prices and implied volatilities. Valuation adjustments may be made to ensure the financial instruments are recorded at fair value. These adjustments include amounts that reflect counterparty credit quality and that consider the Company's own creditworthiness in determining the fair value of its trading assets and liabilities. For additional information related to the valuation methodologies used for certain financial assets and financial liabilities measured at fair value, and information about the Company's valuation processes, see Note 11 "Fair Value Measurement and Fair Value of Financial Instruments" to our Consolidated Financial Statements in Part II, Item 8. “Financial Statements and Supplementary Data” in our 2019 Form 10-K.

Fair Value Hierarchy

In determining fair value, the Company maximizes the use of observable market inputs and minimizes the use of unobservable inputs. Observable inputs reflect market-derived or market-based information obtained from independent sources, while unobservable inputs reflect the Company’s estimate about market data. Based on the observability of the significant inputs used, the Company classifies its fair value measurements in accordance with the three-level hierarchy as defined by GAAP. This hierarchy is based on the quality, observability and reliability of the information used to determine fair value. For additional information related to the fair value hierarchy, see Note 11 "Fair Value Measurement and Fair Value of Financial Instruments" to our Consolidated Financial Statements in Part II, Item 8. “Financial Statements and Supplementary Data” in our 2019 Form 10-K.

The following table presents information about significant unobservable inputs related to the Company’s significant Level 3 assets and liabilities at March 31, 2020.

	March 31, 2020
(Dollars in millions)	Level 3 Fair Value		Valuation Technique	Significant Unobservable Input(s)	Range of Inputs		Weighted Average
Securities available for sale:
Direct bank purchase bonds	$	940	Return on equity	Market-required return on capital	8.0 - 10.0	%	9.9	%
				Probability of default	0.0 - 25.0		0.4
				Loss severity	10.0 - 45.0		20.1

The direct bank purchase bonds generally use a return on equity valuation technique. This technique uses significant unobservable inputs such as market-required return on capital, probability of default and loss severity. Increases (decreases) in any of these inputs in isolation would result in a lower (higher) fair value measurement.

Fair Value Measurement on a Nonrecurring Basis

Certain assets may be measured at fair value on a nonrecurring basis. These assets are subject to fair value adjustments that result from the application of the lower of cost or fair value accounting or write-downs of individual assets. For assets measured at fair value on a nonrecurring basis during the three months ended March 31, 2020 and 2019 that were still held on the consolidated balance sheet as of the respective periods ended, the following tables present the fair value of such assets by the level of valuation assumptions used to determine each fair value adjustment.

Note 9—Derivative Instruments and Other Financial Instruments Used For Hedging

The Company enters into certain derivative and other financial instruments primarily to assist customers with their risk management objectives and to manage the Company’s exposure to interest rate risk. When entering into derivatives on behalf of customers, the Company generally acts as a financial intermediary by offsetting a significant portion of the market risk for these derivatives with third parties. The Company may also enter into derivatives for other risk management purposes. All derivative instruments are recognized as assets or liabilities on the consolidated balance sheets at fair value.

Counterparty credit risk is inherent in derivative instruments. In order to reduce its exposure to counterparty credit risk, the Company utilizes credit approvals, limits, monitoring procedures and master netting and credit support annex agreements. Additionally, the Company considers counterparty credit quality and the creditworthiness of the Company in estimating the fair value of derivative instruments.

Note 9—Derivative Instruments and Other Financial Instruments Used For Hedging (Continued)

The table below presents the notional amounts and fair value amounts of the Company's derivative instruments reported on the consolidated balance sheets, segregated between derivative instruments designated and qualifying as hedging instruments and derivative instruments not designated as hedging instruments as of March 31, 2020 and December 31, 2019. Asset and liability values are presented gross, excluding the impact of legally enforceable master netting and credit support annex agreements. The fair value of asset and liability derivatives designated and qualifying as hedging instruments and derivatives designated as other risk management are included in other assets and other liabilities, respectively. The fair value of asset and liability trading derivatives are included in trading account assets and trading account liabilities, respectively.

We recognized net gains of $23 million on other risk management derivatives for the three months ended March 31, 2020, and net losses of $9 million on other risk management derivatives for the three months ended March 31, 2019, which are included in other noninterest income.

Derivatives Designated and Qualifying as Hedging Instruments

The Company uses interest rate derivatives to manage the financial impact on the Company from changes in market interest rates. These instruments are used to manage interest rate risk relating to specified groups of assets and liabilities, primarily LIBOR-based commercial loans and debt issuances. Derivatives that qualify for hedge accounting are designated as either fair value or cash flow hedges.

Cash Flow Hedges

From time to time, the Company uses interest rate derivatives to hedge the risk of changes in cash flows attributable to changes in the designated interest rate on LIBOR indexed loans, and to a lesser extent, to hedge interest rate risk on rollover debt.

The Company used interest rate derivatives with an aggregate notional amount of $13.3 billion at March 31, 2020 to hedge the risk of changes in cash flows attributable to changes in the designated interest rates from variable rate loans. The Company used interest rate derivatives with an aggregate notional amount of $53 million at March 31, 2020 to hedge the risk of changes in cash flows attributable to changes in the designated interest rate on LIBOR indexed short-term borrowings. At March 31, 2020, the weighted average remaining life of the active cash flow hedges was 2.8 years.

For cash flow hedges, changes in the fair value of the hedging instruments is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged cash flows are recognized in net interest income. At March 31, 2020, the Company expects to reclassify approximately $65 million of income from AOCI to net interest income during the twelve months ending March 31, 2021. This amount could differ from amounts actually realized due to changes in interest rates, hedge terminations and the addition of other hedges subsequent to March 31, 2020.

Offsetting Financial Assets and Liabilities

The Company primarily enters into derivative contracts with counterparties utilizing standard International Swaps and Derivatives Association Master Agreements and Credit Support Annex Agreements. These agreements generally establish the terms and conditions of the transactions, including a legal right to set-off amounts payable and receivable between the Company and a counterparty, regardless of whether or not such amounts have matured or have contingency features. For additional information related to offsetting of financial assets and liabilities, refer to Note 5 "Securities Financing Arrangements" to these Consolidated Financial Statements.

Note 12—Commitments, Contingencies and Guarantees

The following table summarizes the Company's commitments.

(Dollars in millions)	March 31, 2020
Commitments to extend credit	$	32,959
Issued standby and commercial letters of credit	4,103
Commitments to enter into forward-starting resale agreements	887
Other commitments	601

Commitments to extend credit are legally binding agreements to lend to a customer provided there are no violations of any condition established in the contract. Commitments have fixed expiration dates or other termination clauses and may require maintenance of compensatory balances. Since many of the commitments to extend credit may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements.

Standby and commercial letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Standby letters of credit are generally contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party, while commercial letters of credit are issued specifically to facilitate foreign or domestic trade transactions. The majority of these types of commitments have remaining terms of 1 year or less. At March 31, 2020, the carrying amount of the Company's standby and commercial letters of credit totaled $3 million. Estimated exposure to loss related to these commitments is covered by the allowance for losses on unfunded commitments. The carrying amounts of the standby and commercial letters of credit and the allowance for losses on unfunded credit commitments are included in other liabilities on the consolidated balance sheet.

The credit risk involved in issuing loan commitments and standby and commercial letters of credit is essentially the same as that involved in extending loans to customers and is represented by the contractual amount of these instruments. Collateral may be obtained based on management's credit assessment of the customer.

Other commitments include collateralized financing activities, commitments to fund principal investments, other securities, and residual value guarantees.

Principal investments include direct investments in private and public companies. The Company issues commitments to provide equity and mezzanine capital financing to private and public companies through direct investments. The timing of future cash requirements to fund such commitments is generally dependent on the investment cycle. This cycle, the period over which privately held companies are funded by private equity investors and ultimately sold, merged, or taken public through an initial offering, can vary based on overall market conditions as well as the nature and type of industry in which the companies operate.

The Company occasionally enters into financial guarantee contracts where a premium is received from another financial institution counterparty to guarantee a portion of the credit risk on interest rate swap contracts entered into between the financial institution and its customer. The Company becomes liable to pay the financial institution only if the financial institution is unable to collect amounts owed to them by their customer. As of March 31, 2020, the current exposure to loss under these contracts totaled $64 million, and the maximum potential exposure to loss in the future was estimated at $82 million.

The Company is subject to various pending and threatened legal actions that arise in the normal course of business. The Company maintains liabilities for losses from legal actions that are recorded when they are determined to be both probable in their occurrence and can be reasonably estimated. Management believes the disposition of all claims currently pending, including potential losses from claims that may exceed the liabilities recorded, and claims for loss contingencies that are considered reasonably possible to occur, will not have a material effect, either individually or in the aggregate, on the Company's consolidated financial condition, results of operations or liquidity.

69

Note 13—Business Segments

The Company has four reportable segments: Regional Bank, Global Corporate & Investment Banking - U.S., Transaction Banking, and MUSA. The Company uses various management accounting methodologies to measure the performance of its segments. Unlike GAAP, there is no standardized or authoritative guidance for management accounting. Consequently, reported results are not necessarily comparable with those presented by other companies and they are not necessarily indicative of the results that would be reported by the business units if they were separate economic entities.

The management reporting accounting methodologies, which are enhanced from time to time, measure segment profitability by assigning balance sheet and statements of income items to each operating segment. Methodologies that are applied to the measurement of segment profitability, which are enhanced from time to time, include a funds transfer pricing system, an activity-based costing methodology, other indirect costs and a methodology to allocate the provision for credit losses.

The funds transfer pricing system assigns a cost of funds or a credit for funds to assets or liabilities based on their type, maturity or repricing characteristics. A segment receives a credit from Corporate Treasury for its funding sources. Conversely, a segment is assigned a charge by Corporate Treasury to fund its assets. Certain indirect costs, such as operations and technology expense, are allocated to the segments based on an activity-based costing methodology. Other indirect costs, such as corporate overhead, are allocated to the segments based on internal surveys and metrics that serve as proxies for estimated usage. During the normal course of business, the Company occasionally changes or updates its management accounting methodologies or organizational structure. Certain non-bank subsidiaries, including MUSA, are reported based on their GAAP results.

PART II. OTHER INFORMATION

Item 1.   Legal Proceedings

We are subject to various pending and threatened legal actions that arise in the normal course of business. We maintain liabilities for losses from legal actions that are recorded when they are determined to be both probable in their occurrence and can be reasonably estimated. We believe the disposition of all claims currently pending, including potential losses from claims that may exceed the liabilities recorded, and claims for loss contingencies that are considered reasonably possible to occur, will not have a material effect, either individually or in the aggregate, on our consolidated financial position, results of operations, or liquidity.

Item 1A.   Risk Factors

For a discussion of risk factors relating to our business, please refer to Part I, Item 1A. "Risk Factors" in our 2019 Form 10-K, which is incorporated by reference herein, in addition to the following information.

Industry Factors

The COVID-19 pandemic has adversely impacted our business and results of operations, and the ultimate impact of the pandemic on the U.S. and global economies, and on our business, results of operations and financial condition, will depend on future developments, which are highly uncertain and cannot be predicted; however, the effects of the pandemic can be reasonably expected to have an adverse impact, which could be material

The COVID-19 pandemic has adversely impacted our business and results of operation, and the ultimate impact will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and responsive actions taken by governmental and regulatory authorities. The pandemic and related governmental actions have negatively impacted the U.S. and global economies, disrupted supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels. In addition, the pandemic has significantly increased economic uncertainty, reduced economic activity, and resulted in temporary closures of many businesses and the institution of social distancing and sheltering in place requirements in many states and communities, including many markets where we have operations. Governments in the U.S. and globally have taken steps to mitigate some of the more severe anticipated economic effects of the virus. Since March 13, 2020, the United States has been operating under a state of emergency declared by President Trump in response to the spread of COVID-19. During March 2020, the U.S. Congress adopted and the President signed into law the CARES Act, which provided for some $2.2 trillion in federal funding for a variety of programs designed to stimulate the U.S. economy and to soften the economic consequences of the pandemic. Also, during March 2020, in response to the pandemic, the Federal Reserve reduced the federal funds rate 1.5 percentage points to .00 to .25 percent, and provided other monetary support to the financial markets and financial institutions in the U.S. There can be no assurance that these and other governmental measures will be effective or achieve their desired results in a timely fashion.

In response to the pandemic, among other actions, the Bank has offered payment relief options to customers that include the option to select an initial three-month forbearance plan for our mortgage and home equity line of credit clients impacted by the COVID-19 outbreak, business loan support through participation in the SBA PPP or other relief borrowing or lending programs, flexible relief programs for our consumer and business credit card clients, including payment deferral, delinquency removal and late fee waivers, and fee refunds, including for overdraft, non-sufficient funds, monthly service charges and ATM fees, for our consumer and business deposit product customers. We expect that the overall impact of these measures on our results of operations will be material and adverse to a degree which cannot be quantified at this time. Future governmental and regulatory actions may require us to provide these and additional types of customer-related responses.

The pandemic, the early economic effects of which began to be felt late in the first quarter 2020, will adversely affect our revenue, and continue to result in the recognition of credit losses in our loan portfolios and increases in our allowance for credit losses, particularly if businesses remain closed, the impact on the global economy worsens, or more customers draw on their lines of credit or seek additional loans to help finance their businesses. As the economic impacts of the pandemic continue, we may need to shift the mix of our loan portfolio. We provide financing to businesses in a number of industries that may be particularly vulnerable to industry-

73

specific economic factors that can adversely impact the performance of our commercial real estate and commercial and industrial credit portfolios. Certain of these industries, such as the retail industry and the energy industry, among others, have been, and can expected to continue to be, adversely impacted by the disruptive and recessionary market conditions caused by the pandemic, which could result in resulting in higher nonperforming assets and elevated levels of charge-offs. The pandemic has recently caused global demand for crude oil to plummet and oil futures prices to fall below zero. Continued or worsening volatility in fuel prices and energy costs could adversely affect businesses in several of these industries, while a prolonged slump in oil, natural gas and coal prices could have adverse consequences for some of our borrowers in the energy sector. Because of changing economic and market conditions affecting issuers, we also may be required to recognize impairments on the securities we hold.

Our business operations may also be disrupted if significant portions of our workforce, including employees of our third-party service providers, are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the pandemic. We have already temporarily closed certain of our branches and offices, and a significant number of our employees are now working remotely rather than in our offices and branches. Remote work arrangements may exacerbate certain risks to our business, including an increased demand for information technology resources, increased risk of phishing and other cybersecurity attacks, and increased information security risk involving, among other risks, the unauthorized dissemination of sensitive personal information or proprietary or confidential information about us, our customers or other third-parties. The governmental restrictions on non-essential business travel can also be expected to adversely impact our bi-coastal and multi-state operations. The pandemic could also disrupt our operations due to absenteeism by infected or ill members of management or other employees, or members of our Board of Directors, making it more difficult to conduct meetings for the management of our affairs. The operations of our clients, customers, suppliers, third party service providers and business partners have also been, and are likely to be further, adversely impacted.

We may also experience financial losses due to a number of operational factors, including, among others: challenges to the availability and reliability of our network due to changes to normal operations or third party disruptions, including potential outages at network providers, call centers and other suppliers; increased cyber fraud risk related to COVID-19, as cybercriminals attempt to profit from the disruption, given increased online banking, e-commerce and other online activity; and new or additional regulatory requirements, which could require additional resources and costs to address. Various banks who participated in the SBA PPP program or other relief borrowing or lending programs have or may have become the subject of purported class-action litigation regarding their activities under the program; there can be no assurance that such litigation will not be brought against other banks who participate in such programs, including the Bank.

These factors may remain prevalent for a significant period of time and may continue to adversely affect our business, results of operations and financial condition even after the COVID-19 outbreak has subsided. The extent to which the COVID-19 outbreak impacts our business, results of operations and financial condition will depend on future developments, which are highly uncertain and are difficult to predict, including, but not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Even after the COVID-19 outbreak has subsided, we may continue to experience materially adverse impacts to our business as a result of the national and global economic impact of the virus, including the availability of credit, adverse impacts on our liquidity and any recession that has occurred or may occur in the future. Market conditions due to the pandemic could also adversely impact our credit ratings. A substantial majority of our assets, deposits and interest and fee income are generated in California. The California state government continues to require residents to shelter in place and to keep non-essential businesses closed in response to COVID-19, as do the state governments in Washington and Oregon. Given that a large portion of our business is generated on the West Coast, a prolonged reduction in economic activity in this region could have an adverse impact, which could be material, on our business, results of operations and financial condition.

There are no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have, and, as a result, the ultimate impact of the outbreak is highly uncertain and subject to change. We do not yet know the full extent of the impacts on our business, results of operations and financial condition, or on the U.S. or global economies or our market areas in particular. Given the many challenges and uncertainties resulting from the coronavirus pandemic, there is a risk that conditions will be substantially

74

different than we are currently expecting. However, the effects of the pandemic can be reasonably expected to have an adverse impact, which could be material, on our business, results of operations and financial condition, and heighten many of our known risks described in the “Risk Factors” section in Item 1A. of Part I our 2019 Form 10-K and in this Report on Form 10-Q.

The COVID-19 pandemic and related governmental and regulatory actions have negatively impacted the U.S. and global economies, significantly increased economic uncertainty and reduced economic activity, resulting in recessionary economic and financial market conditions, which are likely to have resultant adverse consequences for the U.S. financial services industry and for MUAH

While the U.S. economy experienced a period of significant expansion in recent years, the COVID-19 pandemic and related governmental and regulatory actions, the early economic effects of which began to be felt late in the first quarter 2020, have negatively impacted the U.S. and global economies, disrupted supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels. In addition, the pandemic has significantly increased economic uncertainty, reduced economic activity, and resulted in temporary closures of many businesses and the institution of social distancing and sheltering in place requirements in many states and communities, including many markets where we have operations. We, and other financial services companies, are impacted to a significant degree by current economic conditions.

Governments in the U.S. and globally have taken steps to mitigate some of the more severe anticipated economic effects of the virus. During March 2020, the U.S. Congress adopted and the President signed into law the CARES Act, which provided for some $2.2 trillion in federal funding for a variety of programs designed to stimulate the U.S. economy and to soften the economic consequences of the pandemic. Also, during March 2020, in response to the pandemic, the Federal Reserve reduced the federal funds rate 1.5 percentage points to .00 to .25 percent, and provided other monetary support to the financial markets and financial institutions in the U.S. There can be no assurance that these and other governmental measures will be effective or achieve their desired results in a timely fashion.

The various governmental stimulus measures introduced in response to the COVID-19 pandemic have increased, and can be expected to continue to increase, federal budget deficits and the national debt level, while tax revenue can be expected to decline along with economic activity. These events can be expected to adversely affect the long-term sovereign credit rating of United States debt, and downgrades by the credit rating agencies with respect to the obligations of the U.S. federal government could occur. Any such downgrades could increase over time the U.S. federal government’s cost of borrowing, which may worsen its fiscal challenges, as well as generate upward pressure on interest rates generally in the U.S., which could, in turn, have adverse consequences for borrowers and the level of business activity. These developments could also create further challenges for the securities business conducted by MUSA, which relies upon both the credit quality of bonds issued by the U.S. federal government and the smooth functioning of the markets using such bonds as collateral, as the COVID-19 pandemic has created significant volatility and disruption in financial markets.

The extent to which the COVID-19 outbreak ultimately impacts the national and global economies will depend on future developments, which are highly uncertain and are difficult to predict, including, but not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. Even after the COVID-19 outbreak has subsided, the U.S and global economies may continue to experience materially adverse impacts and continuing or worsening recessionary conditions. We do not yet know the full extent of the impacts of the COVID-19 pandemic on the U.S. or global economies or our market areas in particular; however, the pandemic may result in prolonged continuing or worsening recessionary economic and financial market conditions, which are likely to have adverse consequences, which could be material, for the U.S. financial services industry and for MUAH.

75

Company Factors

California economic conditions, have been, and can reasonably be expected to continue to be, adversely affected by the COVID-19 pandemic, which could adversely affect our business

A substantial majority of our assets, deposits and interest and fee income is generated in California. As a result, poor economic conditions in California may cause us to incur losses associated with higher default rates and decreased collateral values in our loan portfolio.

In response to the COVID-19 pandemic, following a declaration of a state of emergency in early March, the California state government issued a strict shelter in place order on March 19, 2020, instituting social distancing requirements and closing all non-essential businesses. The shelter in place order does not have a specific termination date. Given the many uncertainties and challenges resulting from the coronavirus pandemic, it is difficult to predict when this shelter in place order will be lifted, and the timing of when, and the extent to which, normal economic and operating conditions can resume in the state.

In the U.S. generally, and in California in particular, the pandemic has significantly increased economic uncertainty, reduced economic activity and increased unemployment levels. While many financial institutions, including the Bank, have offered payment relief to mortgage and home equity line of credit customers impacted by the COVID-19 outbreak, among other customer-related responses, the pandemic may significantly affect the commercial and residential real estate markets in the U.S. generally, and in California and our other market areas in particular, decreasing property values, increasing the risk of defaults and reducing the value of real estate collateral. There can be no assurance that home prices in California and our other market areas will not decline as a result of the recessionary financial and market conditions created by the COVID-19 pandemic.

In addition, although the State of California has historically experienced budget shortfalls or deficits, during the past several years, California’s budgetary situation improved considerably. However, the various economic and health measures introduced by the legislature and the governor of the State of California in response to the COVID-19 pandemic have increased state spending at a time when the current economic slowdown can be expected to result in reduced state tax revenues, perhaps for a prolonged period.

Also, municipalities and other governmental units within California have experienced budgetary difficulties and several California municipalities filed for protection under the Bankruptcy Code. As a result, concerns have arisen regarding the outlook for the governmental obligations of California municipalities and other governmental units. If the budgetary and fiscal difficulties of the California state government and California municipalities and other governmental units recur or economic conditions in California decline, we expect that our level of problem assets could increase and our prospects for growth could be impaired.

For a number of years in the past decade, California has also experienced severe drought, wildfires or other natural disasters. It can be expected that these events will continue to occur from time to time in the areas served by the Bank, and that the consequences of these natural disasters, including programs of public utility public safety power outages when weather conditions and fire danger warrant, may adversely affect the Bank’s business and that of its customers. It is also possible that climate change may be increasing the severity or frequency of adverse weather conditions, thus increasing the impact of these types of natural disasters on our business and that of our customers.

Our credit ratings are important in order to maintain liquidity

Major credit rating agencies regularly evaluate and provide credit ratings of the securities of MUAH and the securities and deposits of MUB and also provide entity ratings for MUAH, MUB and MUSA. Their ratings of our long-term and short-term debt obligations and of our deposits and our entity ratings are based on a number of factors including our financial strength, ability to generate earnings, and other factors, some of which are not entirely within our control, such as conditions affecting the financial services industry and the economy. In light of the continually evolving conditions in the financial services industry, the financial markets and the economy, changes to credit rating methodologies and the ongoing assessment of our current and expected satisfaction of various rating criteria, no assurance can be given that we will maintain our current ratings. Further, as a result of the COVID-19 pandemic and concerns over the financial impacts of the virus outbreak on the U.S. and global economies and the credit effects on companies, the major credit rating agencies may reevaluate and revise the outlook or credit ratings for many companies, including MUAH, which could result in a negative ratings action or downgrade.

76

If our long-term or short-term credit ratings suffer substantial downgrades, particularly if lowered below investment grade, such downgrades could adversely affect access to liquidity and could significantly increase our cost of funds (especially our wholesale funding), trigger additional collateral or funding requirements and decrease the number of commercial depositors, investors and counterparties willing or permitted to lend to us, thereby curtailing our business operations and reducing our ability to generate income. For additional information, see "Management's Discussion and Analysis of Financial Condition and Results of Operations - Risk Management - Liquidity Risk Management" in Part II, Item 7. of our 2019 Form 10-K and "Management's Discussion and Analysis of Financial Condition and Results of Operations - Risk Management - Liquidity Risk Management” in Part I, Item 2. of this Form 10-Q.

Certain of our derivative instruments contain provisions that require us to maintain a specified credit rating. If our credit rating were to fall below the specified rating, the counterparties to these derivative instruments could terminate the contract and demand immediate payment or demand immediate and ongoing full overnight collateralization for those derivative instruments in net liability positions.

Adverse changes in the credit ratings, operations or prospects of our parent companies, MUFG Bank, Ltd. and MUFG, could also adversely impact our credit ratings. In April 2020, Fitch placed the ratings of MUAH, MUB and MUSA on ratings watch negative as a result of Fitch’s downgrade of MUFG’s ratings to A-/F1 outlook stable from A/F1 outlook negative. This action follows Fitch’s recent revision of the U.S. Bank Sector Outlook and Rating Outlook, both to negative from stable, driven by concerns over the financial impact from COVID-19. On May 1, 2020, Fitch affirmed MUAH, MUB and MUSA's long and short-term ratings. The ratings watch negative was removed on the long-term rating and a negative outlook was assigned. The negative outlook reflects Fitch's view that there are significant operating environment challenges due to the disruption to economic activity and financial markets from the coronavirus pandemic. In April 2020, S&P revised the outlook on MUFG to stable from positive due to S&P’s expectation that economic strain from the COVID–19 pandemic will put prolonged pressure on asset quality and revenue lowering the likelihood of being upgraded. Subsequently, S&P revised MUAH, MUB, and MUSA’s outlook to stable from positive. The stable outlook reflects S&P’s expectation that MUAH will remain a core banking subsidiary of MUFG. Furthermore, any change in MUAH’s stand–alone credit profile will not affect MUAH's credit rating, which, S&P believes will remain closely tied to MUFG. For additional information, refer to Part I, Item 1A. "Risk Factors" in our 2019 Form 10-K under the caption “MUFG Bank Ltd.’s and Mitsubishi UFJ Financial Group’s credit ratings and financial or regulatory condition could adversely affect our operations”.

We rely on third parties for important products and services

Third-party vendors provide key components of our business infrastructure such as internet connections, network access and mutual fund distribution and, although we monitor their performance, we do not control their actions. Among other services provided by these vendors, third-party vendors have played and will continue to play a key role in the implementation of our technology enhancement and replacement projects, including our Transformation and Rewiring Programs. The federal banking agencies have issued enhanced guidance and are examining with increasing scrutiny financial institutions’ diligence conducted on and oversight of their third-party vendors. Any problems caused by these third parties, including those as a result of their not providing us their services for any reason or their performing their services poorly or failing to meet legal and regulatory requirements, could adversely affect our ability to deliver products and services to our customers, implement our technology enhancement and replacement projects or otherwise conduct our business and also could result in disputes with such vendors over the performance of their services to us, as well as adverse regulatory consequences for us. Replacing these third-party vendors on economically feasible terms may not always be possible or within our control and could also entail significant delay and expense.

The Bank relies on vendors providing overseas delivery centers in India for some of its support services. The Government of India has imposed a nation-wide quarantine in response to the pandemic, requiring employees of these centers to work remotely, generally at home, and outside of the security of these centers. This has increased the cybersecurity risk associated with these relationships. In addition, if key employees or groups of employees at the various vendors used by the Bank were to contract the COVID-19 disease and cannot work, this could adversely impact the vendor’s ability to fulfill its obligations to the Bank.

In recent years, there has been consolidation in the number of major vendors supporting financial institutions such as the Bank, resulting in increased concentration risk for such institutions. This risk could be increased if the pandemic results in failures or additional combinations of such vendors.

Summary of Significant Accounting Policies and Nature of Operations (Policies)

3 Months Ended

Mar. 31, 2020

Accounting Policies [Abstract]

Basis of Presentation

The unaudited Consolidated Financial Statements of MUFG Americas Holdings Corporation, its subsidiaries, and its consolidated variable interest entities (the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Rules and Regulations of the SEC. However, they do not include all of the disclosures necessary for annual financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation have been included.

Use of Estimates

The preparation of financial statements in conformity with GAAP also requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Although such estimates contemplate current conditions and management’s expectations of how they may change in the future, it is reasonably possible that actual results could differ significantly from those estimates. This could materially affect the Company’s results of operations and financial condition in the near term. Critical estimates made by management in the preparation of the Company’s financial statements include, but are not limited to, the allowance for credit losses (Note 3 "Loans and Allowance for Loan Losses"), goodwill impairment, fair value of financial instruments (Note 8 "Fair Value Measurement and Fair Value of Financial Instruments"), pension accounting (Note 11 "Employee Pension and Other Postretirement Benefits"), income taxes, and transfer pricing.

Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provides new guidance on the accounting for credit losses for instruments that are within its scope. This new guidance is commonly referred to as the CECL model. For loans and debt securities accounted for at amortized cost, certain off-balance sheet credit exposures, net investments in leases, and trade receivables, the ASU requires an entity to recognize its estimate of credit losses expected over the life of the financial instrument or exposure by incorporating forward-looking information, such as reasonable and supportable forecasts, in the entity's assessment of the collectability of financial assets. Lifetime expected credit losses on purchased financial assets with credit deterioration will be recognized as an allowance with an offset to the cost basis of the asset. For available for sale debt securities, the new standard will require recognition of expected credit losses by recognizing an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. The Company adopted the ASU on January 1, 2020, and recorded an increase to the allowance for credit losses of $199 million, primarily due to an increase in the allowance for consumer loans, offset by a $52 million deferred tax asset, and a $147 million cumulative-effect adjustment reduction to retained earnings.

Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies disclosure requirements on fair value measurements to improve their effectiveness. The guidance permits entities to consider materiality when evaluating fair value measurement disclosures and, among other modifications, requires certain new disclosures related to Level 3 fair value measurements. The Company adopted the ASU on January 1, 2020. The guidance only affects disclosures in the Notes to the Consolidated Financial Statements and will not affect the Company’s financial position or results of operations.

Summary of Significant Accounting Policies and Nature of Operations

Summary of Significant Accounting Policies and Nature of Operations

MUFG Americas Holdings Corporation (MUAH) is a financial holding company, bank holding company and intermediate holding company whose principal subsidiaries are MUFG Union Bank, N.A. (MUB or the Bank) and MUFG Securities Americas Inc. (MUSA). MUAH provides a wide range of financial services to consumers, small businesses, middle-market companies and major corporations nationally and internationally. The Company also provides various business, banking, financial, administrative and support services, and facilities for MUFG Bank, Ltd. (formerly The Bank of Tokyo-Mitsubishi UFJ, Ltd.) in connection with the operation and administration of MUFG Bank, Ltd.'s business in the U.S. (including MUFG Bank, Ltd.'s U.S. branches). All of the Company's issued and outstanding shares of common stock are owned by MUFG Bank, Ltd. and MUFG. The unaudited Consolidated Financial Statements of MUFG Americas Holdings Corporation, its subsidiaries, and its consolidated variable interest entities (the Company) have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the Rules and Regulations of the SEC. However, they do not include all of the disclosures necessary for annual financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the first quarter of 2020 are not necessarily indicative of the operating results anticipated for the full year. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 (2019 Form 10-K).

The preparation of financial statements in conformity with GAAP also requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Although such estimates contemplate current conditions and management’s expectations of how they may change in the future, it is reasonably possible that actual results could differ significantly from those estimates. This could materially affect the Company’s results of operations and financial condition in the near term. Critical estimates made by management in the preparation of the Company’s financial statements include, but are not limited to, the allowance for credit losses (Note 3 "Loans and Allowance for Loan Losses"), goodwill impairment, fair value of financial instruments (Note 8 "Fair Value Measurement and Fair Value of Financial Instruments"), pension accounting (Note 11 "Employee Pension and Other Postretirement Benefits"), income taxes, and transfer pricing.

Allowance for loan losses

Allowance for loan losses is a valuation account that is deducted from the assets’ amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off.

Management develops and documents its systematic methodology for determining the allowance by

first dividing its portfolio into two segments - the commercial segment and consumer segment. The Company

further divides its portfolio segments into classes based on initial measurement attributes, risk characteristics or its method of monitoring and assessing credit risk. The classes for the Company include commercial and industrial, commercial mortgage, construction, residential mortgage and home equity, and other consumer loans. While the Company's methodology attributes portions of the allowance to specific portfolio segments and classes, the allowance estimate is provided to cover all credit losses expected in the loan portfolio.

The Company's methodology for estimating the allowance balance uses relevant available information, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made to account for differences between current and expected future conditions and those reflected in historical loss information. The allowance is measured on a collective basis when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated on an individual basis.

The collectively-assessed allowance methodology incorporated an economic forecast over a 36-month period when ASU 2016-13, Measurement of Credit Losses on Financial Instruments, was adopted as of January 1, 2020. Beyond the 36-month economic forecast, the allowance methodology reverted to average historical loss information on a straight-line basis over a 24-month period. However, the economic forecast was shortened to a 24-month period during the first quarter of 2020 due to heightened volatility and uncertainty in the economy due to the emergence of COVID-19. No change was made to the 24-month straight-line reversion to historical loss information. These timeframes are regularly reviewed and approved by management and may be adjusted if economic conditions warrant.

An expected loss approach is used to estimate the collectively-assessed allowance for both the commercial and consumer portfolio segments. Expected loss is calculated as the product of PD, LGD, and EAD modeled parameters that are projected on a monthly basis over the assets’ remaining contractual lives. The sum of each month’s expected loss calculation results in the collectively-assessed allowance estimate. Expected loss models use historical loss information and a variety of economic assumptions to estimate PD, LGD, and EAD. These models are tailored to different loan segments, classes and products by changing the economic variables or their weighting in the calculation used to estimate expected losses.

The allowance is an estimate of expected credit losses over the remaining contractual term of each

asset. Expected prepayments are incorporated into the estimation of the EAD for each asset over the asset’s remaining term, which shortens the expected remaining term. Contractual term is not adjusted for expected extensions, renewals, and modifications unless we have a reasonable expectation that a TDR will be executed with a borrower. Credit cards do not have defined contractual terms. In order to estimate the expected credit losses on actively used revolving credit card balances, we make assumptions about expected payments and expected spending on the unconditionally cancelable unfunded amount at the measurement date. Expected spending after the measurement date reduces the expected payments that are allocated to the outstanding balance at the measurement date. Expected credit losses are calculated only on the outstanding balances component at the measurement date, which is amortized by applying the proportion of the expected payment allocated to the outstanding balance. Expected payments applied to the expected spending after the measurement date are effectively excluded from the analysis because unconditionally cancelable unfunded commitments are not reservable.

Loans that do not share risk characteristics are evaluated individually to determine the allowance balance. Loans assessed individually include larger nonaccruing loans within the commercial portfolio, TDRs, reasonably expected TDRs and collateral-dependent loans. Collateral-dependent loans are generally individually-assessed for allowance purposes. Collateral-dependent assets' expected credit losses are assessed when the fair value of the collateral is less than the amortized cost basis of the asset. Collateral-dependent assets are evaluated in this manner when foreclosure is probable, or when repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty. Estimated costs to sell are included in the estimate when repayment is expected by the sale of the collateral. Collateral-dependent assets are generally secured by real estate collateral. When the discounted cash flow method is used to determine the allowance for individually-assessed loans, management does not adjust the interest rate used to discount expected cash flows to incorporate expected prepayments.

Management implements qualitative adjustments to the collectively-assessed allowance to account for the risks not incorporated in the model between current conditions and those reflected in the historical loss information used to estimate the models. These qualitative factors include changes in credit policies, problem loan trends, identification of new risks not incorporated into the modeling framework, credit concentrations, changes in lending management and other external factors. Qualitative adjustments are also used to adjust the collectively-assessed allowance to account for risks attributed to imprecision in the economic forecast and when risks emerge that impact specific portfolio components (i.e., natural disasters).

TDRs are loans where we have granted a concession to a borrower as a result of the borrower experiencing financial difficulty and, consequently, we receive less than the current market-based compensation for loans with similar risk characteristics. Such loans' allowance is measured either individually or in pools with similar risk characteristics. The allowance for a TDR loan is measured using the same method as all other loans when evaluated in pools. The allowance for individually assessed TDR loans can be measured using a discounted cash flow methodology, or by evaluating the fair value of the collateral, if collateral dependent. When the value of a concession cannot be measured using a method other than the discounted cash flow method, the value of a concession is measured by discounting the expected future cash flows at the original interest rate of the loan. When we have a reasonable expectation that a TDR loan may be executed with a borrower at the evaluation date, we may modify the allowance calculation to align with the expected modification terms, which may include modifying the expected contractual term.

We do not record an allowance for accrued interest receivable on loans held for investment, which is included in other assets on the consolidated balance sheet. Uncollectible accrued interest is reversed through interest income.

Allowance for Credit Losses on Debt Securities

All securities held to maturity are explicitly or implicitly guaranteed by U.S. government entities or agencies and have a long history of no credit losses. No credit losses are expected on these assets and thus no allowance is estimated on securities held to maturity.

Securities available for sale are composed of assets that are explicitly or implicitly guaranteed by U.S. government entities or agencies and non-agency-backed assets that are highly rated and have not incurred credit losses historically. Unrealized losses on available for sale securities arise from changes in market conditions, not credit losses. Direct purchase bonds are not externally rated but are assessed quarterly to determine whether credit losses exist. Unrealized losses on the direct purchase bonds have arisen from higher current expected returns on capital as compared with required rates of return on capital on the bonds at origination. No credit losses are expected on these assets and thus no allowance is estimated on securities available for sale.

Allowance for Credit Losses on Securities Borrowed or Purchased under Resale Agreements

Securities borrowed or purchased under resale agreements are also subject to allowance estimation, however management has no history of credit losses on these assets and has portfolio monitoring practices that ensure collateral is maintained at appropriate levels. As borrowers have a history of replenishing collateral securing the financial assets, when needed, and are expected to continue to maintain such behavior in the future, no allowance is estimated on these assets, consistent with the practical expedient methodology described in ASC 326-20-35-6. Management reviews these portfolios on a quarterly basis to confirm the conclusion of no allowance for credit losses remains appropriate.

Allowance for Credit Losses on Unfunded Credit Commitments

The Company maintains an allowance for losses on unfunded credit commitments for the contractual term over which we are exposed to credit risk that is not unconditionally cancelable by the Company. The Company's allowance methodology for unfunded credit commitments is the same as that used for the allowance for the other collectively-evaluated assets and includes an estimate of commitments that are expected to fund over the remaining contractual term. The allowance for losses on unfunded credit commitments is classified as other liabilities on the balance sheet, with the changes recognized in the provision for credit losses.

Recently Adopted Accounting Pronouncements

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provides new guidance on the accounting for credit losses for instruments that are within its scope. This new guidance is commonly referred to as the CECL model. For loans and debt securities accounted for at amortized cost, certain off-balance sheet credit exposures, net investments in leases, and trade receivables, the ASU requires an entity to recognize its estimate of credit losses expected over the life of the financial instrument or exposure by incorporating forward-looking information, such as reasonable and supportable forecasts, in the entity's assessment of the collectability of financial assets. Lifetime expected credit losses on purchased financial assets with credit deterioration will be recognized as an allowance with an offset to the cost basis of the asset. For available for sale debt securities, the new standard will require recognition of expected credit losses by recognizing an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. The Company adopted the ASU on January 1, 2020, and recorded an increase to the allowance for credit losses of $199 million, primarily due to an increase in the allowance for consumer loans, offset by a $52 million deferred tax asset, and a $147 million cumulative-effect adjustment reduction to retained earnings.

Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies disclosure requirements on fair value measurements to improve their effectiveness. The guidance permits entities to consider materiality when evaluating fair value measurement disclosures and, among other modifications, requires certain new disclosures related to Level 3 fair value measurements. The Company adopted the ASU on January 1, 2020. The guidance only affects disclosures in the Notes to the Consolidated Financial Statements and will not affect the Company’s financial position or results of operations.

Loans and Allowance for Loan Losses

Loans and Allowance for Loan Losses

The following table provides the outstanding balances of loans held for investment at March 31, 2020 and December 31, 2019.

(Dollars in millions)	March 31, 2020			December 31, 2019
Loans held for investment:
Commercial and industrial	$	29,872		$	26,338
Commercial mortgage	16,943			16,895
Construction	1,583			1,511
Lease financing	980			1,001
Total commercial portfolio	49,378			45,745

Total loans held for investment(3)	89,786			88,213
Allowance for loan losses	(1,152		)	(538		)
Loans held for investment, net	$	88,634		$	87,675

(1) Includes home equity loans of $2,006 million and $2,049 million at March 31, 2020 and December 31, 2019, respectively.

(2) Other consumer loans substantially include unsecured consumer loans and consumer credit cards.

(3) Includes $279 million and $320 million at March 31, 2020 and December 31, 2019, respectively, for net unamortized (discounts) and premiums and deferred (fees) and costs.

Accrued interest receivable on loans held for investment and securities totaled $469 million at March 31, 2020 and is included in the other assets on the consolidated balance sheet.

Allowance for Loan Losses

The provision for loan losses was $448 million for the three months endedMarch 31, 2020, largely due to the impact of COVID-19 and the corresponding deterioration in the economic environment on the collectively-assessed allowance for credit losses. The provision for loan losses was $274 million and $174 million for the commercial and consumer loan segments, respectively, largely due to economic deterioration observed late in the first quarter of 2020. Downgrades of several obligors also contributed to the commercial segment provision. The economic forecast incorporated management's expectations at March 31, 2020, which included declining gross domestic product, unemployment approaching double digits by June 2020 and lower stock prices in 2020, with a modest recovery emerging in the fourth quarter of 2020 and continuing into subsequent years. The collectively-assessed allowance for credit losses estimate also incorporated management’s qualitatively-determined model adjustment overlays that reflect the anticipated loss mitigating impact of monetary and fiscal stimulus policies and loan modification programs, and additional qualitative adjustments largely driven by estimated impacts of COVID-19 that are not otherwise incorporated into the collectively-assessed modeling methodology. The following tables provide a reconciliation of changes in the allowance for loan losses by portfolio segment.

Credit Quality Indicators

Management analyzes the Company's loan portfolios by applying specific monitoring policies and procedures that vary according to the relative risk profile and other characteristics within the various loan portfolios. Loans within the commercial portfolio segment are classified as either pass or criticized. Criticized credits are those that have regulatory risk ratings of special mention, substandard or doubtful; classified credits are those that have regulatory risk ratings of substandard or doubtful. Special mention credits are potentially weak, as the borrower has begun to exhibit deteriorating trends, which, if not corrected, may jeopardize repayment of the loan and result in further downgrade. Substandard credits have well-defined weaknesses, which, if not corrected, could jeopardize the full satisfaction of the debt. A credit classified as doubtful has critical weaknesses that make full collection improbable on the basis of currently existing facts and conditions.

The following tables summarize the loans in the commercial portfolio segment monitored for credit quality based on regulatory risk ratings.

The Company also monitors the credit quality for substantially all of its consumer portfolio segment using credit scores provided by FICO and refreshed LTV ratios. FICO credit scores are refreshed at least quarterly to monitor the quality of the portfolio. Refreshed LTV measures the principal balance of the loan as a percentage of the estimated current value of the property securing the loan. Home equity loans are evaluated using combined LTV, which measures the principal balance of the combined loans that have liens against the property (including unused credit lines for home equity products) as a percentage of the estimated current value of the property securing the loans. The LTV ratios are refreshed on a quarterly basis, using the most recent home pricing index data available for the property location. 

The following tables summarize the loans in the consumer portfolio segment based on refreshed FICO scores and refreshed LTV ratios at March 31, 2020 and December 31, 2019. The December 31, 2019 amounts presented reflect unpaid principal balances less partial charge-offs.

Troubled Debt Restructurings

The following table provides a summary of the Company’s recorded investment in TDRs as of March 31, 2020 and December 31, 2019. The summary includes those TDRs that are on nonaccrual status and those that continue to accrue interest. The Company had $33 million and $61 million in commitments to lend additional funds to borrowers with loan modifications classified as TDRs as of March 31, 2020 and December 31, 2019, respectively.

(Dollars in millions)	March 31, 2020		December 31, 2019

Residential mortgage and home equity	186		192
Other consumer	1		1
Total consumer portfolio	187		193
Total restructured loans	$	476	$	563

For the first quarter of 2020, TDR modifications in the commercial portfolio segment were substantially composed of maturity extensions and conversions of revolving lines of credit into fixed terms. In the consumer portfolio segment, modifications were largely composed of maturity extensions and interest rate reductions. There were no charge-offs related to TDR modifications for the three months ended March 31, 2020 and March 31, 2019. For the commercial and consumer portfolio segments, the allowance for loan losses for TDRs was measured on an individual loan basis or in pools with similar risk characteristics.

The following tables provide the pre- and post-modification outstanding recorded investment amounts of TDRs as of the date of the restructuring that occurred during the three months ended March 31, 2020 and 2019.

(1) Represents the recorded investment in the loan immediately prior to the restructuring event.

(2) Represents the recorded investment in the loan immediately following the restructuring event. It includes the effect of paydowns that were required as part of the restructuring terms.

The recorded investment amounts of TDRs at the date of default, for which there was a payment default during the three months ended March 31, 2020 and 2019, and where the default occurred within the first twelve months after modification into a TDR were de minimis. A payment default is defined as the loan being 60 days or more past due.

For loans in the consumer portfolio in which allowance for loan losses is measured using the present value of expected future cash flows discounted at the loan’s effective interest rate, historical payment defaults and the propensity to redefault are some of the factors considered when determining the allowance for loan losses.

On March 22, 2020, the federal bank regulatory agencies issued joint guidance advising that the agencies have confirmed with the staff of the FASB that short-term modifications due to COVID-19 made on a good faith basis to borrowers who were current prior to relief, are not TDRs. On March 27, 2020 the CARES Act, which provides relief from TDR classification for certain COVID-19 related loan modifications, was signed into law. For COVID-19 related loan modifications which occurred from March 1, 2020, through March 31, 2020, and met the loan modification criteria under either the CARES Act or the criteria specified by the regulatory agencies, we elected to suspend TDR accounting for such loan modifications.

The Company performs goodwill impairment tests on an annual basis as of April 1, and between annual tests if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying amount. [The Company adopted Accounting Standards Update No. 2017-04, Simplifying the Test for Goodwill Impairment ("ASU 2017-04") effective July 1, 2019. This standard eliminates Step 2 from the goodwill impairment test.] Instead, the Company performs its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit.

[During the third quarter of 2019, due to the decline in interest rates and slower growth than previously forecasted, cash flow projections for certain reporting units were revised lower. The combination of these events led management to believe that it was more likely than not that the fair values of certain reporting units were below carrying value. As a result, the Company initiated an interim quantitative impairment test of goodwill allocated to three of its reporting units: Consumer Banking, Commercial Banking and Real Estate Industries, and Global Corporate & Investment Banking - U.S.]

[The Company estimated the fair value of its reporting units using a combination of the income and the market approaches. The income approach estimates the fair value of the reporting units by discounting management’s projections of each reporting unit’s cash flows, including a terminal value to estimate the fair value of cash flows beyond the final year of projected results, using a discount rate derived from the Capital Asset Pricing Model. The market approach incorporates comparable public company price to tangible book value and price to earnings multiples. ]

[Certain projected cash flows used to estimate fair value of the reporting units were revised lower than previous projections due to the combination of the following factors: the decline in interest rates through September 30, 2019 and a change in the Company’s expectation that interest rates will remain lower than previously assumed; updates to key loan growth and loan mix assumptions in the forecast to address the Company’s declining net interest margin; and a reduction of the expected growth and cash flow contribution of new initiatives based on a revised economic outlook. Multiples selected in the market approach to estimate fair value were also revised lower than those used in the most recent annual quantitative impairment test due to lower reporting unit earnings.]

[Upon completing the quantitative impairment test, the Company recorded an impairment charge of $1.6 billion in the third quarter of 2019, which represented the entire amount of goodwill allocated to the Consumer Banking reporting unit and a portion of the goodwill allocated to the Global Corporate & Investment Banking - U.S. reporting unit, which had $667 million allocated goodwill remaining after the impairment. ]

Summary of Significant Accounting Policies and Nature of Operations (Tables)

3 Months Ended

Mar. 31, 2020

Accounting Policies [Abstract]

Schedule of Impact as a Result of Adopting ASU 2017-07

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which provides new guidance on the accounting for credit losses for instruments that are within its scope. This new guidance is commonly referred to as the CECL model. For loans and debt securities accounted for at amortized cost, certain off-balance sheet credit exposures, net investments in leases, and trade receivables, the ASU requires an entity to recognize its estimate of credit losses expected over the life of the financial instrument or exposure by incorporating forward-looking information, such as reasonable and supportable forecasts, in the entity's assessment of the collectability of financial assets. Lifetime expected credit losses on purchased financial assets with credit deterioration will be recognized as an allowance with an offset to the cost basis of the asset. For available for sale debt securities, the new standard will require recognition of expected credit losses by recognizing an allowance for credit losses when the fair value of the security is below amortized cost and the recognition of this allowance is limited to the difference between the security’s amortized cost basis and fair value. The Company adopted the ASU on January 1, 2020, and recorded an increase to the allowance for credit losses of $199 million, primarily due to an increase in the allowance for consumer loans, offset by a $52 million deferred tax asset, and a $147 million cumulative-effect adjustment reduction to retained earnings.

Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies disclosure requirements on fair value measurements to improve their effectiveness. The guidance permits entities to consider materiality when evaluating fair value measurement disclosures and, among other modifications, requires certain new disclosures related to Level 3 fair value measurements. The Company adopted the ASU on January 1, 2020. The guidance only affects disclosures in the Notes to the Consolidated Financial Statements and will not affect the Company’s financial position or results of operations.

At March 31, 2020, the Company did not have the intent to sell any securities in an unrealized loss position before a recovery of the amortized cost, which may be at maturity. The Company also believes that it is more likely than not that it will not be required to sell the securities prior to recovery of amortized cost.

Agency residential and commercial mortgage-backed securities consist of securities guaranteed by a U.S. government corporation, such as Ginnie Mae, or a government-sponsored agency such as Freddie Mac or Fannie Mae. These securities are collateralized by residential and commercial mortgage loans and may be prepaid at par prior to maturity. The unrealized losses on agency residential mortgage-backed securities resulted from changes in interest rates and not from changes in credit quality. At March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities because the Company determined that the strength of the issuers’ guarantees through direct obligations or support from the U.S. government is sufficient to protect the Company from losses.

Commercial mortgage-backed securities are collateralized by commercial mortgage loans and are generally subject to prepayment penalties. The unrealized losses on commercial mortgage-backed securities resulted from higher market yields since purchase. Cash flow analysis of the underlying collateral provides an estimate of impairment, which is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities.

The Company’s CLOs consist of Cash Flow CLOs. A Cash Flow CLO is a structured finance product that securitizes a diversified pool of loan assets into multiple classes of notes. Cash Flow CLOs pay the note holders through the receipt of interest and principal repayments from the underlying loans unlike other types of CLOs that pay note holders through the trading and sale of underlying collateral. Unrealized losses typically arise from widening credit spreads and deteriorating credit quality of the underlying collateral. Cash flow analysis of the underlying collateral provides an estimate of impairment, which is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities.

Direct bank purchase bonds are not rated by external credit rating agencies. The unrealized losses on these bonds resulted from a higher return on capital expected by the secondary market compared with the return on capital required at the time of origination when the bonds were purchased. The Company estimates the unrealized loss for each security by assessing the underlying collateral of each security. The Company estimates the portion of loss attributable to credit based on the expected cash flows of the underlying collateral using estimates of current key assumptions, such as probability of default and loss severity. Cash flow analysis of the underlying collateral provides an estimate of impairment, which is performed quarterly when the fair value of a security is lower than its amortized cost and potential impairment is identified. Based on the analysis performed as of March 31, 2020, the Company expects to recover the entire amortized cost basis of these securities.

The fair value of debt securities available for sale by contractual maturity are shown below. Actual maturities may differ from contractual maturities because borrowers may have the right to prepay obligations with or without prepayment penalties.

Amortized cost is defined as the original purchase cost, adjusted for any accretion or amortization of a purchase discount or premium, less principal payments and any impairment previously recognized in earnings. The carrying amount is the difference between the amortized cost and the amount recognized in OCI. The amount recognized in OCI primarily reflects the unrealized gain or loss at date of transfer from available for sale to the held to maturity classification, net of amortization, which is recorded in interest income on securities.

The Company’s securities held to maturity with a continuous unrealized loss position at March 31, 2020 and December 31, 2019 are shown below, separately for periods less than 12 months and 12 months or more.
