NOTE REGARDING FORWARD-LOOKING STATEMENTS

This report includes forward-looking statements, which include expectations for our operations and business and our assumptions for those expectations. Do not rely unduly on forward-looking statements. Actual results might differ significantly compared to our expectations.

(1)Pre-tax, pre-provision income 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) attributable to MUAH excluding intangible asset amortization and goodwill impairment 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.). 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. 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)Net interest margin is 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, 2020 (2020 Form 10-K) along with the following discussion and analysis of our consolidated financial position and results of operations for the period ended June 30, 2021 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 $165.3 billion at June 30, 2021.

Executive Overview

We are providing you with an overview of what we believe are the most significant factors and developments that affected our second quarter 2021 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 second quarter of 2021, revenue was comprised of 50% net interest income and 50% 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

10

reliability of our various funding sources to help ensure that we have sufficient liquidity when adverse situations arise.

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 income attributable to MUAH was $311 million and $690 million for the three and six months ended June 30, 2021, respectively, compared with a net income (loss) attributable to MUAH of $22 million and $(284) million in the same periods in 2020. The increase in net income was largely due to a reversal of provision for credit losses of $174 million and $349 million for the three and six months ended June 30, 2021, respectively, due to an improvement in our economic forecast, compared with a provision for credit losses of $361 million and $831 million for the three and six months ended June 30, 2020, respectively, which was substantially driven by the impact of COVID-19 and the corresponding deterioration in the economic environment.

Capital Ratios

The Company's capital ratios continued to exceed all well-capitalized and minimum regulatory thresholds for BHCs, as applicable. The Company's U.S. Basel III Common Equity Tier 1, Tier 1 and Total risk-based capital ratios were 15.89%, 15.89% and 16.58%, respectively, at June 30, 2021. The Company's Tier 1 leverage ratio was 9.74% at June 30, 2021.

Net interest income for the three and six months ended June 30, 2021 decreased compared with the same periods in 2020 due to decreases in net interest income from MUB and MUSA. The decrease in net interest income from MUB was largely due to a lower net interest margin resulting from lower interest rates and the unfavorable effect of noninterest bearing deposits in a declining rate environment, and a decrease in earning assets. MUB's decrease in earning assets was primarily due to a decrease in residential mortgage and home equity and other consumer loans, partially offset by increases in securities, interest bearing deposits in banks, and commercial and industrial loans. The decrease in net interest income from MUSA was largely due to lower trading asset yields despite higher trading asset balances.

Noninterest Income and Noninterest Expense    

The following tables display our noninterest income and noninterest expense for the three and six months ended June 30, 2021 and 2020.

Total noninterest income	$	711	$	809	$	(98)	(12)		$	1,443	$	1,421	$	22	2

Noninterest income decreased during the three months ended June 30, 2021 compared with the same period in 2020 largely due to decreases in gains on sales of securities, investment banking and syndication fees, and MUSA trading account activities. Noninterest income increased during the six months ended June 30, 2021 compared with the same period in 2020 largely due to increases in fees from affiliates from services provided to MUFG Bank, Ltd. regarding its U.S. business under the master services agreement, and certain counterparty valuation adjustments included in trading account activities. These increases were partially offset by prior period gains on sale of securities. The increase in other, net was largely due to a gain on disposition of Transaction Banking's debt servicing and securities custody services business and an increase 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 are included in trading account activities.

The increase in noninterest expense for the three and six months ended June 30, 2021 compared with the same periods in 2020 was largely driven by a technology-related asset impairment recorded in the second quarter of 2021 and increases in costs associated with services provided to MUFG Bank, Ltd. under the master services agreement, partially offset by a prior period impairment of a retail credit card intangible. For additional information regarding costs associated with services provided to MUFG Bank, Ltd. and related fee income earned, see the calculation of the adjusted efficiency ratio in "Non-GAAP Financial Measures" in this "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Income Tax Expense

For the six months ended June 30, 2021, income tax expense was $89 million and the effective tax rate was 12% reflecting tax credits to be recognized during 2021. For the six months ended June 30, 2020, income tax expense was $64 million and the effective tax rate was negative 28% due to excess tax credits that were recognized during 2020. In the second quarter of 2021, income tax expense was $19 million and the effective tax rate was 6%, reflecting the impact of a decrease in the effective tax rate from 16% as of March 31, 2021 to 12% as of June 30, 2021. In the second quarter of 2020, income tax expense was $39 million and the effective tax rate was 68%, reflecting the impact of a decrease in the effective tax rate from negative 9% as of March 31, 2020 to negative 28% as of June 30, 2020.

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" and Note 17 "Income Taxes" to our consolidated financial statements in Part II, Item 8. “Financial Statements and Supplementary Data” in our 2020 Form 10-K.

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 $1,351 million and $1,590 million at June 30, 2021 and December 31, 2020, respectively.

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

(3)Includes $71 million and $127 million at June 30, 2021 and December 31, 2020, respectively, for net unamortized (discounts) and premiums and deferred (fees) and costs.

Loans held for investment decreased from December 31, 2020 to June 30, 2021, largely due to a reduction in residential mortgage and home equity, other consumer, and commercial mortgage loans. The commercial and industrial loans portfolio had $1.7 billion of PPP loans outstanding at June 30, 2021.

Total deposits increased $1.6 billion from December 31, 2020 to June 30, 2021 largely due to increases in noninterest bearing deposits from our consumer and business clients, partially offset by decreases in money market accounts and time deposits.

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 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 June 30, 2021, 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 2021. Under the Capital Plan and Tailoring Rules of the Federal Reserve, MUAH, as a Category IV firm, is subject to CCAR supervisory stress testing requirements on an every other year basis in even years; the Company voluntarily opted-in to Federal Reserve-run stress testing in 2021. MUAH also submitted its required annual capital plan to the Federal Reserve in April 2021. CCAR assesses capital adequacy levels under various scenarios to determine if covered BHCs and IHCs would have sufficient capital to continue operations throughout times of economic and financial market stress. The Company's 2021 capital plan submission encompassed an evaluation of a range of expected and stressed economic and financial market scenarios, and included an assessment of expected sources and uses of capital over a prescribed planning horizon, a description of all capital actions within that time frame, and a discussion of any proposed business plan changes that are likely to have a material impact on capital adequacy. In June 2021, the Federal Reserve released its 2021 supervisory DFAST stress testing results and MUAH received notice from the Federal Reserve of its preliminary revised stress capital buffer which would take effect October 1, 2021 as informed by the 2021 supervisory DFAST stress testing results. For additional information regarding the Company's capital plan, 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 2020 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 current standardized capital conservation buffer of 4.4% for MUAH and 2.5% for MUB (for a total minimum Common Equity Tier 1 capital ratio of 9.9% for MUAH and 7.0% for MUB) 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. bank regulatory agencies. The impact is reflected in the capital ratios presented below.

The following tables summarize the calculation of MUAH’s risk-based capital ratios in accordance with the U.S. Basel III Rules as of June 30, 2021 and December 31, 2020.

(1)The minimum capital requirement includes MUAH's standardized capital conservation buffer of 4.4%.

(2)Tier 1 capital divided by quarterly average assets (excluding certain disallowed assets, primarily goodwill and other intangibles).

The increase in the Company's risk-based capital ratios was driven primarily by net income earned during the six months ended June 30, 2021 and a decrease in risk-weighted assets.

(1)The minimum capital requirement includes a capital conservation buffer of 2.5%.

(2)Tier 1 capital divided by quarterly average assets (excluding certain disallowed assets, primarily goodwill and other intangibles).

The increase in MUB's risk-based capital ratios was driven primarily by net income earned during the six months ended June 30, 2021 and a decrease in risk-weighted assets.

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 June 30, 2021. 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 June 30, 2021 and December 31, 2020.

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 2020 Form 10-K. For additional information regarding risks related to our business, please refer to Part I, Item 1A. "Risk Factors" in our 2020 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 2020 Form 10-K.

Allowance for Credit Losses

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. Understanding our policies on the allowance for credit losses is fundamental to understanding our consolidated financial condition and consolidated results of operations. Accordingly, our significant accounting policies on the allowance for credit losses are discussed in detail in 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” and in “Allowance for Credit Losses” in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2020 Form 10-K. For additional information regarding our allowance for loan losses, 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.

The reversal of provision for credit losses was $174 million and $349 million for the three and six months ended June 30, 2021, respectively, consisting of a reversal of provision for loan losses of $167 million and a reversal of provision for losses on unfunded credit commitments of $7 million for the three months ended June 30, 2021, and a reversal of provision for loan losses of $358 million and a provision for losses on unfunded credit commitments of $9 million for the six months ended June 30, 2021. The reversals of provision for loan losses were $137 million and $280 million for the commercial loan segment and $30 million and $78 million for the consumer loan segment for the three and six months ended June 30, 2021, respectively, largely due to an improvement in the Company's economic forecast. The economic forecast incorporated management's expectations at June 30, 2021, which included a continuing economic recovery in 2021 and subsequent years, and significantly lower COVID-19-related uncertainty than at December 31, 2020 due to fiscal stimulus and economic indicators that were better than previously forecasted. Lower consumer loan segment balances also contributed to that segment's reversal of provision.

The allowance for loan losses was $858 million at June 30, 2021, compared with $1,273 million at December 31, 2020. Our ratio of allowance for loan losses to total loans held for investment was 1.09% as of June 30, 2021 and 1.55% as of December 31, 2020. Our ratio of allowance for credit losses to total loans held for investment was 1.19% as of June 30, 2021 and 1.63% as of December 31, 2020. Net loans charged off to average total loans held for investment were 0.15% and 0.14% for the three and six months ended June 30, 2021, respectively, compared with 0.24% and 0.26% for the three and six months ended June 30, 2020, respectively.

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 2020 Form 10-K.

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

	June 30, 2021			December 31, 2020			Increase (Decrease)
(Dollars in millions)							Amount		Percent

(1)Troubled debt restructurings exclude COVID-19-related loan modifications, which are discussed below in "Troubled Debt Restructurings."

The decrease in criticized credits is due to improvements in the commercial real estate, power and utilities and aviation 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.

23

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 June 30, 2021 and December 31, 2020. 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.

					As a Percentage of Ending Loan Balances

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 did not classify loan modifications, which were largely payment deferrals, that met the criteria under either the CARES Act or the criteria specified by the regulatory agencies as TDRs. At June 30, 2021, $58 million of modified commercial loans and $520 million of modified consumer loans were still in deferral and not classified as TDRs. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and nonaccrual status will not be impacted during the deferral period. Interest income will continue to be recognized over the contractual life of the loan.

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 $29 million and $45 million at June 30, 2021 and at December 31, 2020, 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. Finance and insurance exceeded 10% of our total loans held for investment at June 30, 2021 and December 31, 2020.

24

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 June 30, 2021, 75% of the Company’s construction loan portfolio was concentrated in California and 7% to borrowers in Oregon. The commercial mortgage loan portfolio consists of loans secured by commercial income properties. At June 30, 2021, 67% of the Company’s commercial mortgage loans were made to borrowers located in California, 6% to borrowers in Washington, and 5% 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 June 30, 2021, substantially all our residential mortgage loans were made to borrowers in California.

At June 30, 2021, payment terms on 44% 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 63%. 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 26% and 25% of these home equity loans and lines were supported by first liens on residential properties at June 30, 2021 and December 31, 2020, 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 June 30, 2021 and December 31, 2020.

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. 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 2020 Form 10-K.

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 November 2020, LIBOR’s administrator, ICE Benchmark Administration Limited, announced that it will consult on its intention to cease the publication of the one week and two month U.S. dollar LIBOR settings as of the end of 2021 and the remaining U.S. dollar LIBOR settings as of June 30, 2023. 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

25

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 phase-out of LIBOR could adversely impact our business and results of operations, and the value of certain financial instruments we hold or have issued" in Part I, Item 1A. "Risk Factors" in our 2020 Form 10-K). We have exposure to IBORs that arise from derivatives and other contracts used for hedging and trading account purposes, loans to commercial customers and consumers (including mortgage loans and other loans), and long-term borrowings.

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 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 periodic updates are provided to 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 utilizing 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.

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.

Treasury, under the oversight of ALCO, is responsible for identifying, managing and reporting on liquidity risk and formulates the funding, liquidity and contingency planning strategies for the Company, the Bank and MUSA. MRM conducts independent oversight and governance of liquidity risk management activities to establish sound policies and effective risk and independent monitoring controls. 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. 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

26

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-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 2020 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 $25.5 billion at June 30, 2021. Our primary funding sources are customer deposits, secured FHLB advances, and unsecured short-term and long-term debt. Total deposits increased $1.6 billion from $102.4 billion at December 31, 2020 to $104.0 billion at June 30, 2021. As of June 30, 2021, the Bank had $4.1 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 $14.9 billion. The Bank maintains a $12.0 billion unsecured bank note program. Available funding under the bank note program was $3.6 billion at June 30, 2021. 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 June 30, 2021, MUAH’s liquidity exceeded 18 months.

MUAH and its subsidiaries may borrow on a long-term basis from MUFG Bank, Ltd. and affiliates. As of June 30, 2021, the Company had total long-term debt issued to MUFG Bank, Ltd. and affiliates of $6.9 billion.

The Company’s total wholesale funding included $14.0 billion of long-term debt (excluding nonrecourse debt) and $0.1 billion of short-term debt at June 30, 2021. 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. The following table provides our credit ratings as of June 30, 2021.

		MUFG Union Bank, N.A.		MUFG Securities Americas Inc.	MUFG Americas Holdings Corporation

(1)On July 12, 2021, MUFG Union Bank, N.A.’s long-term and short-term senior debt ratings were upgraded to A2 and P-1, respectively.

For additional information, including information about rating agency assessments, see “Our credit ratings are important in order to maintain liquidity; our credit ratings could be adversely affected by negative changes in the credit ratings of our parent companies” in Part I, Item 1A. "Risk Factors" in our 2020 Form 10-K.

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 cybersecurity incidents. See “Our business and operations are subject to a wide array of cybersecurity risks" in Part I, Item 1A. “Risk Factors” in our 2020 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 2020 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 that have already occurred or are expected to occur. 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 the 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 estimates and has discussed these estimates with the Audit & Finance Committee.

The Company continuously monitors inputs used when performing its annual goodwill impairment such as the cash flow projections and market comparables 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.

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

28

significant accounting policies are discussed in detail in our 2020 Form 10-K. There were no material changes to our critical accounting estimates during the second quarter of 2021.

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 and six months ended June 30, 2021 and 2020. Management believes that this ratio provides useful supplemental information regarding the Company's business results.

	For the Three Months Ended						For the Six Months Ended
(Dollars in millions)	June 30, 2021			June 30, 2020			June 30, 2021			June 30, 2020
Net income (loss) attributable to MUAH	$	311		$	22		$	690		$	(284)
Add: Intangible asset amortization, net of tax	2			4			5			9
Net income (loss) attributable to MUAH, excluding intangible asset amortization (a)	$	313		$	26		$	695		$	(275)
Average MUAH stockholders' equity	$	17,383		$	16,849		$	17,252		$	16,688
Less: Goodwill	1,391			1,764			1,398			1,764
Less: Intangible assets, except mortgage servicing rights	197			224			198			241
Less: Deferred tax liabilities related to goodwill and intangible assets	(17)			(20)			(16)			(19)
Average MUAH tangible common equity (b)	$	15,812		$	14,881		$	15,672		$	14,702
Return on average MUAH tangible common equity (1) (a)/(b)	7.92		%	0.70		%	8.87		%	(3.74)		%

(1) Annualized.

The following table shows the calculation of the adjusted efficiency ratio for the three and six months ended June 30, 2021 and 2020. 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						For the Six Months Ended
(Dollars in millions)	June 30, 2021			June 30, 2020			June 30, 2021			June 30, 2020

Less: Costs associated with services provided to MUFG Bank, Ltd. branches in the U.S.	358			342			715			661

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 Securities Exchange Act of 1934 (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 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 June 30, 2021, 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. MUFG Bank has a limited number of previously issued letters of credit and guarantees and in some cases, provided limited remittance and other settlement services mainly in connection with its Japanese customer transactions with counterparties in Iran, which transactions are reviewed to assess whether they are exempt from applicable Iran-related sanctions or otherwise permitted by OFAC. These transactions did not involve U.S. dollars or clearing services of U.S. banks for the settlement of payments. For the quarter ended June 30, 2021, 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 June 30, 2021, the average aggregate balance of deposits held in these accounts represented less than 0.05 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. We understand that MUFG Bank has taken the recent sanctions related developments into account and will continue to monitor transactions relating to Iran in order to comply with applicable U.S. and Japanese regulations as well as U.S., Japanese and other international sanctions.

Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer concluded that these disclosure controls and procedures were effective.

Notes to Consolidated Financial Statements

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

MUFG Americas Holdings Corporation (MUAH or the Company) 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. 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 MUAH, its subsidiaries, and its consolidated variable interest entities 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 second quarter of 2021 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, 2020 (2020 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, income taxes, and transfer pricing.

At June 30, 2021, 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.

Note 2—Securities (Continued)

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 June 30, 2021, the Company expected 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.

Residential mortgage-backed securities are collateralized by residential mortgage loans and may be prepaid at par prior to maturity. Commercial mortgage-backed securities are collateralized by commercial mortgage loans and are generally subject to prepayment penalties. The unrealized losses on residential and commercial mortgage-backed securities resulted from higher market yields since purchase. Cash flow analysis of the underlying collateral provides an estimate of recoverability and is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of June 30, 2021, 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 recoverability and is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of June 30, 2021, the Company expects to recover the entire amortized cost basis of these securities.

Other debt securities primarily consist of direct bank purchase bonds, which 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 recoverability and 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 June 30, 2021, 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 June 30, 2021 and December 31, 2020 are shown below, separately for periods less than 12 months and 12 months or more.

Allowance for Loan Losses

The reversals of provision for loan losses were $137 million and $280 million for the commercial loan segment and $30 million and $78 million for the consumer loan segment for the three and six months ended June 30, 2021, respectively, largely due to an improvement in the Company's economic forecast. The economic forecast incorporated management's expectations at June 30, 2021, which included a continuing economic recovery in 2021 and subsequent years, and significantly lower COVID-19-related uncertainty than at December 31, 2020 due to fiscal stimulus and economic indicators that were better than previously forecasted. Lower consumer loan segment balances also contributed to that segment's reversal of provision.

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 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 June 30, 2021 and December 31, 2020.

Troubled Debt Restructurings

The following table provides a summary of the Company’s recorded investment in TDRs as of June 30, 2021 and December 31, 2020. The summary includes those TDRs that are on nonaccrual status and those that continue to accrue interest. The Company had $38 million and $24 million in commitments to lend additional funds to borrowers with loan modifications classified as TDRs as of June 30, 2021 and December 31, 2020, respectively.

Residential mortgage and home equity	229		248
Other consumer	1		2
Total consumer portfolio	230		250
Total restructured loans	$	463	$	491

During the second quarter of 2021, TDR modifications in the commercial portfolio segment were substantially composed of maturity extensions. 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 six months ended June 30, 2021 and June 30, 2020. 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.

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 did not classify loan modifications, which were largely payment deferrals, that met the criteria under either the CARES Act or the criteria specified by the regulatory agencies as TDRs. At June 30, 2021, $58 million of modified commercial loans and $520 million of modified consumer loans were still in deferral and not classified as TDRs. For loan modifications that include a payment deferral and are not TDRs, the borrower’s past due and nonaccrual status will not be impacted during the deferral period. Interest income will continue to be recognized over the contractual life of the loan.

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 and six months ended June 30, 2021 and 2020.

	For the Three Months Ended June 30, 2021				For the Six Months Ended June 30, 2021

The following tables provide the recorded investment amounts of TDRs at the date of default, for which there was a payment default during the three and six months ended June 30, 2021, and where the default occurred within the first twelve months after modification into a TDR. A payment default is defined as the loan being 60 days or more past due.

Total	$	28	$	28

For loans in the consumer portfolio in which impairment 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.

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 June 30, 2021 and December 31, 2020.

	June 30, 2021
	Consolidated Assets						Consolidated Liabilities

Leasing investments	310		111		421		5		5
Total consolidated VIEs	$	310	$	192	$	502	$	21	$	21

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 and rail 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.

Note 4—Variable Interest Entities (Continued)

Unconsolidated VIEs

The following tables present the Company’s carrying amounts related to the unconsolidated VIEs at June 30, 2021 and December 31, 2020. 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 six months ended June 30, 2021 and June 30, 2020, noncash increases in unfunded commitments on LIHC investments were de minimis and $52 million, respectively, included in 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 and six months ended June 30, 2021 and 2020.

	For the Three Months Ended				For the Six Months Ended

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 June 30, 2021 and December 31, 2020.

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 June 30, 2021 and December 31, 2020.

For additional information on these derivative instruments, see Note 9 "Derivative Instruments and Other Financial Instruments Used For Hedging" to these consolidated financial statements.

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 2020 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 2020 Form 10-K.

The following table presents information about significant unobservable inputs related to the Company’s significant Level 3 assets and liabilities at June 30, 2021.

	June 30, 2021
(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	$	708	Return on equity	Market-required return on capital	8.0-10.0	%	10.0	%
				Probability of default	0.1-4.1		0.3
				Loss severity	10.0-45.0		17.6
Other	$	512	Discounted cash flow	Discount rate	1.1-4.5		3.5
				Liquidity adjustment	0.8-2.9		2.2

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.

Other securities available for sale generally use a discounted cash flow valuation technique. This technique uses significant unobservable inputs such as discount rate and liquidity adjustment. 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 and six months ended June 30, 2021 and 2020 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 June 30, 2021 and December 31, 2020. 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 losses of $11 million and $16 million on other risk management derivatives for the three and six months ended June 30, 2021, respectively, and net gains of $5 million and $28 million for the three and six months ended June 30, 2020, respectively, 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 $10.0 billion at June 30, 2021 to hedge the risk of changes in cash flows attributable to changes in the designated interest rates from variable rate loans. At June 30, 2021, the weighted average remaining life of the active cash flow hedges was 2.4 years.

For cash flow hedges, changes in the fair value of the hedging instruments are 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 June 30, 2021, the Company expects to reclassify approximately $106 million of income from AOCI as an increase to net interest income during the twelve months ending June 30, 2022. This amount could differ from amounts actually realized due

to changes in interest rates, hedge terminations and the addition of other hedges subsequent to June 30, 2021.

The following table presents the amount and location of the net gains and losses recorded in the Company’s consolidated statements of income and changes in stockholders' equity for derivative instruments designated as cash flow hedges for the three and six months ended June 30, 2021 and 2020.

Fair Value Hedges

The Company engaged in an interest rate hedging strategy in which interest rate derivatives were associated with specified interest bearing liabilities, in order to convert the liabilities from fixed rate to floating rate instruments. This strategy mitigated the changes in fair value of the hedged liabilities caused by changes in the designated interest rate.

The Company includes gains or losses on the hedging derivatives and the offsetting changes in the fair values of the hedged liabilities attributable to their designated benchmark interest rate in the same line item in the consolidated statements of income. The following table presents derivative instruments, by contract type, used in fair value hedging relationships, as well as the gains (losses) recorded on such derivatives and the related change in fair values of the hedged liabilities for the three and six months ended June 30, 2021. The Company did not have any fair value hedges during 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)	June 30, 2021
Commitments to extend credit	$	39,330
Issued standby and commercial letters of credit	4,255
Commitments to enter into forward-starting resale agreements	1,940
Other commitments	1,304

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 June 30, 2021, 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 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.

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 include a funds transfer pricing system, an activity-based costing methodology, other indirect costs and a methodology to allocate the provision for credit losses. During the second quarter of 2021, the Company revised its methodology for allocating certain costs to its Global Corporate & Investment Banking - U.S. and Japanese Corporate Banking segments. Prior period results have been revised to conform to the current presentation.

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. In addition, 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, operating results 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 2020 Form 10-K, which is incorporated by reference herein, in addition to the following information.

Company Factors

Climate change could have a material adverse impact on us and our customers

Physical damage caused by extreme weather conditions and natural disasters resulting from climate change, as well as governments’ measures to strengthen climate-related regulations, and societal responses to climate change, may adversely affect the business and financial condition of us and our customers, including our credit portfolio. The Company has significant operations and customers in California, Oregon and Washington and elsewhere in the U.S., which could be adversely impacted by severe weather events. Such events could disrupt our operations or the operations of customers or third parties on which we rely. Such events could also result in market volatility or negatively impact our customers’ ability to pay outstanding loans, or result in the deterioration of the value of our collateral or insurance shortfalls. These events could reduce the Company’s earnings and cause volatility in the Company’s financial results for any fiscal quarter or year and have a material adverse effect on the Company’s financial condition and results of operations. Additional legislation and regulatory requirements and changes in consumer preferences relating to climate change, including those associated with the transition to a low-carbon economy, could increase the operating expenses of, or otherwise adversely impact, the Company, its businesses or its customers. We and our customers may face cost increases, asset value reductions, operating process changes, reduced availability of insurance, and the like, as a result of governmental actions or societal responses to climate change and our corporate value may be impaired and our business and results of operations may be adversely affected if our effort to address climate change-related risks or to make appropriate disclosure proves or is deemed inappropriate.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Nature of Operations	Summary of Significant Accounting Policies and Nature of OperationsMUFG Americas Holdings Corporation (MUAH or the Company) 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. 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 MUAH, its subsidiaries, and its consolidated variable interest entities 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 second quarter of 2021 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, 2020 (2020 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, income taxes, and transfer pricing.

At June 30, 2021, 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 June 30, 2021, the Company expected 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.

Residential mortgage-backed securities are collateralized by residential mortgage loans and may be prepaid at par prior to maturity. Commercial mortgage-backed securities are collateralized by commercial mortgage loans and are generally subject to prepayment penalties. The unrealized losses on residential and commercial mortgage-backed securities resulted from higher market yields since purchase. Cash flow analysis of the underlying collateral provides an estimate of recoverability and is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of June 30, 2021, 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 recoverability and is performed quarterly when the fair value of a security is lower than its amortized cost. Based on the analysis performed as of June 30, 2021, the Company expects to recover the entire amortized cost basis of these securities.

Other debt securities primarily consist of direct bank purchase bonds, which 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 recoverability and 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 June 30, 2021, 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 June 30, 2021 and December 31, 2020 are shown below, separately for periods less than 12 months and 12 months or more.

Variable Interest Entities

Variable Interest Entities

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 June 30, 2021 and December 31, 2020.

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 and rail 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 June 30, 2021 and December 31, 2020. 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 six months ended June 30, 2021 and June 30, 2020, noncash increases in unfunded commitments on LIHC investments were de minimis and $52 million, respectively, included in 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 and six months ended June 30, 2021 and 2020.

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.

Transfers and Servicing [Abstract]

Securities Financing Arrangements

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 June 30, 2021 and December 31, 2020.

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.

Fair Value Measurement and Fair Value of Financial Instruments

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 2020 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 2020 Form 10-K.

The following table presents information about significant unobservable inputs related to the Company’s significant Level 3 assets and liabilities at June 30, 2021.

	June 30, 2021
(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	$	708	Return on equity	Market-required return on capital	8.0-10.0	%	10.0	%
				Probability of default	0.1-4.1		0.3
				Loss severity	10.0-45.0		17.6
Other	$	512	Discounted cash flow	Discount rate	1.1-4.5		3.5
				Liquidity adjustment	0.8-2.9		2.2

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.

Other securities available for sale generally use a discounted cash flow valuation technique. This technique uses significant unobservable inputs such as discount rate and liquidity adjustment. 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 and six months ended June 30, 2021 and 2020 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.

Commitments, Contingencies and Guarantees

Commitments, Contingencies and Guarantees

The following table summarizes the Company's commitments.

(Dollars in millions)	June 30, 2021
Commitments to extend credit	$	39,330
Issued standby and commercial letters of credit	4,255
Commitments to enter into forward-starting resale agreements	1,940
Other commitments	1,304

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 June 30, 2021, 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 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.

Segment Reporting [Abstract]

Business Segments

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 include a funds transfer pricing system, an activity-based costing methodology, other indirect costs and a methodology to allocate the provision for credit losses. During the second quarter of 2021, the Company revised its methodology for allocating certain costs to its Global Corporate & Investment Banking - U.S. and Japanese Corporate Banking segments. Prior period results have been revised to conform to the current presentation.

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.

Summary of Significant Accounting Policies and Nature of Operations (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	The unaudited consolidated financial statements of MUAH, its subsidiaries, and its consolidated variable interest entities 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, income taxes, and transfer pricing.
