NOTE 1 - BASIS OF PRESENTATION AND ACCOUNTING POLICIES

Organization

The accompanying unaudited consolidated financial statements were prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation were included. The results of operations for the six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. Certain items in prior periods were reclassified to conform to the current presentation. For further information, refer to the consolidated financial statements and footnotes thereto included in the Annual Report of Comerica Incorporated and Subsidiaries (the Corporation) on Form 10-K for the year ended December 31, 2019.

Allowance for Credit Losses

        The allowance for credit losses includes both the allowance for loan losses and the allowance for credit losses on lending-related commitments.

        The Corporation disaggregates the loan portfolio into segments for purposes of determining the allowance for credit losses. These segments are based on the level at which the Corporation develops, documents and applies a systematic methodology to determine the allowance for credit losses. The Corporation's portfolio segments are business loans and retail loans. Business loans include the commercial, real estate construction, commercial mortgage, lease financing and international loan portfolios. Retail loans consist of residential mortgage and consumer loans, including home equity loans.

        Effective January 1, 2020, the Corporation adopted the provisions of Accounting Standards Update (ASU) No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," commonly referred to as the current expected credit loss (CECL) model, for all financial assets, except those accounted for at fair value through net income, using the modified retrospective approach.

        Under Topic 326, current expected credit losses are estimated over the contractual life of the loan portfolio, considering all available relevant information, including historical and current conditions as well as reasonable and supportable forecasts of future events. The previous accounting principle estimated probable, estimable losses inherent in the portfolio.

        At adoption, the Corporation’s estimate of current expected credit losses in accordance with Topic 326 resulted in a $17 million day-one decrease in the overall allowance for credit losses, from $668 million at December 31, 2019 under the incurred loss model. The Corporation recognized a corresponding $13 million increase to retained earnings and a $4 million reduction to deferred tax assets. A similar adjustment at December 31, 2019 would have caused a 2-basis-point increase in the Common Equity Tier 1 (CET1) capital ratio. Business loans, comprising approximately 91 percent of the Corporation’s total loan portfolio at transition, consist of loans and lending arrangements with generally short contractual maturities. As a result, the allowance for credit losses for business loans decreased $42 million. The allowance for credit losses increased $25 million for retail loans, given their longer contractual maturities.

        Topic 326 also requires expected credit losses on available-for-sale (AFS) debt securities to be recorded as an allowance for credit losses. For certain types of debt securities, such as U.S. Treasuries and other securities with government guarantees, entities may expect zero credit losses. The zero-loss expectation applies to all the Corporation’s securities and no allowance for credit losses was recorded on its AFS securities portfolio at transition.

Allowance for Loan Losses

        The allowance for loan losses is estimated on a quarterly basis and represents management’s estimates of current expected credit losses in the Corporation’s loan portfolio. Pools of loans with similar risk characteristics are collectively evaluated while loans that no longer share risk characteristics with loan pools are evaluated individually.

        Collective loss estimates are determined by applying reserve factors, designed to estimate current expected credit losses, to amortized cost balances over the remaining contractual life of the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools. Business loans are assigned to pools based primarily on business line and the Corporation’s internal risk rating system. For retail loans, pools are based on loan type, past due status and credit scores. Reserve factors are based on estimated probability of default for each pool, set to a default horizon based on contractual life, and loss given default. Historical estimates are calibrated to economic forecasts over the reasonable and supportable forecast period based on the projected performance of specific economic variables that statistically correlate with each of the probability of default and loss given default pools.

        The calculation of current expected credit losses is inherently subjective, as it requires management to exercise judgment in determining appropriate factors used to determine the allowance. Some of the most significant factors in the quantitative allowance estimate are assigning internal risk ratings to loans, selecting the economic forecasts used to calibrate the reserve factors and determining the reasonable and supportable forecast period.

•Internal Risk Ratings: Loss factors are dependent on loan risk ratings for business loans. Risk ratings are assigned at origination, based on inherent credit risk, and may be updated based on new information that becomes available, periodic reviews of credit quality, a change in borrower performance or modifications to lending agreements.

•Economic Forecasts: Management selects economic variables it believes to be most relevant based on the composition of the loan portfolio and customer base, including forecasted levels of employment, gross domestic product, corporate bond and treasury spreads, industrial production levels, consumer and commercial real estate price indices as well as housing statistics. Different economic forecast scenarios ranging from more benign to more severe are evaluated each reporting period to forecast losses over the contractual life of the loan portfolio.

•Forecast Period: Economic forecasts are applied over the period management believes it can estimate reasonable and supportable forecasts. Forecast periods may be adjusted in response to changes in the economic environment. To estimate losses for contractual periods that extend beyond the forecast horizon, the Corporation reverts to an average historical loss experience. The Corporation typically forecasts economic variables over a two-year horizon, followed by an immediate reversion to an average historical loss experience that generally incorporates a full economic cycle. Management reviews this methodology on at least an annual basis.

        The allowance for loan losses also includes qualitative adjustments to bring the allowance to the level management believes is appropriate based on factors that have not otherwise been fully accounted for, including adjustments for foresight risk, input imprecision and model imprecision. Foresight risk reflects the inherent imprecision in forecasting economic variables, including determining the depth and duration of economic cycles and their impact to relevant economic variables. The Corporation may make qualitative adjustments based on its evaluation of different forecast scenarios and known recent events impacting relevant economic variables. Input imprecision factors address the risk that certain model inputs may not reflect all available information including (i) risk factors that have not been fully addressed in internal risk ratings, (ii) changes in lending policies and procedures, (iii) changes in the level and quality of experience held by lending management, (iv) imprecision in the risk rating system and (v) limitations in data available for certain loan portfolios. Model imprecision considers known model limitations and model updates not yet fully reflected in the quantitative estimate.

         The determination of the appropriate qualitative adjustment is based on management's analysis of current and expected economic conditions and their impact to the portfolio, as well as internal credit risk movements and a qualitative assessment of the lending environment, including underwriting standards. Management recognizes the sensitivity of various assumptions made in the quantitative modeling of expected losses and may adjust reserves depending upon the level of uncertainty that currently exists in one or more assumptions.

        Credit losses for loans that no longer share risk characteristics with the loan pools are estimated on an individual basis. Individual credit loss estimates are typically performed for nonaccrual loans and modified loans classified as troubled debt restructurings (TDRs) and are based on one of several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected cash flows. The Corporation considers certain loans to be collateral-dependent if the borrower is experiencing financial difficulty and management expects repayment for the loan to be substantially through the operation or sale of the collateral. For collateral-dependent loans, loss estimates are based on the fair value of collateral, less estimated cost to sell (if applicable). Collateral values supporting individually evaluated loans are assessed quarterly and appraisals are typically obtained at least annually.

        The total allowance for loan losses is sufficient to absorb expected credit losses over the contractual life of the portfolio. Unanticipated events impacting the economy, including political instability or global events affecting the U.S. economy, could cause changes to expectations for current conditions and economic forecasts that result in an unanticipated increase in the allowance. Significant increases in current portfolio exposures or changes in credit characteristics could also increase the amount of the allowance. Such events, or others of similar nature, may result in the need for additional provision for credit losses in order to maintain an allowance that complies with credit risk and accounting policies.

        Loans deemed uncollectible are charged off and deducted from the allowance. Recoveries on loans previously charged off are added to the allowance.

        Credit losses are not estimated for accrued interest receivable as interest that is deemed uncollectible is written off through interest income.

Allowance for Credit Losses on Lending-Related Commitments

The allowance for credit losses on lending-related commitments estimates current expected credit losses on collective pools of letters of credit and unused commitments to extend credit based on reserve factors, determined in a manner similar to business loans, multiplied by a probability of draw estimate, based on historical experience and credit risk, applied to commitment amounts. The allowance for credit losses on lending-related commitments is included in accrued expenses and other liabilities on the Consolidated Balance Sheets, with the corresponding charge included in the provision for credit losses on the Consolidated Statements of Comprehensive Income.

Goodwill

        Effective January 1, 2020, the Corporation prospectively adopted the provisions of ASU No. 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” (ASU 2017-04), eliminating the second step of goodwill impairment testing, under which the implied fair value of goodwill was determined as if the reporting unit were being acquired in a business combination. Under ASU 2017-04, the Corporation will compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit’s fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. The adoption of ASU 2017-04 did not impact the Corporation’s current financial condition or results of operations.

        Goodwill, included in accrued income and other assets on the Consolidated Balance Sheets, is initially recorded as the excess of the purchase price over the fair value of net assets acquired in a business combination and is subsequently evaluated at least annually for impairment. Goodwill impairment testing is performed at the reporting unit level, equivalent to a business segment or one level below. The Corporation has three reporting units: the Commercial Bank, the Retail Bank and Wealth Management.

        The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and may elect to perform a quantitative impairment analysis or first conduct a qualitative analysis to determine if a quantitative analysis is necessary. Additionally, the Corporation evaluates goodwill impairment on an interim basis if events or changes in circumstances between annual tests indicate additional testing may be warranted to determine if goodwill might be impaired. Factors considered in the assessment of the likelihood of impairment include macroeconomic conditions, industry and market considerations, stock performance of the Corporation and its peers, financial performance of the reporting units, and previous results of goodwill impairment tests, amongst other factors. Based on the results of the qualitative analysis, the Corporation determines whether a quantitative test is deemed necessary. The quantitative test compares the estimated fair value of identified reporting units with their carrying amount, including goodwill. If the estimated fair value of the reporting unit is less than the carrying value, an impairment charge would be recorded for the excess, not to exceed the amount of goodwill allocated to the reporting unit.

Software

        Effective January 1, 2020, the Corporation adopted the provisions of ASU No. 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract," using a prospective approach for implementation costs incurred subsequent to the adoption of the standard. Amortization expense from capitalized implementation costs of hosting arrangements that are service contracts and fees associated with the hosting elements of the arrangements, are included in software expense in the Consolidated Statements of Comprehensive Income, along with other software-related expenses. For the three- and six-month periods ended June 30, 2020, software expense included $8 million and $15 million of hosting fees that would have previously been included in outside processing fee expense.

        Capitalized software, stated at cost less accumulated amortization, includes purchased software, capitalizable application development costs associated with internally developed software and cloud computing arrangements, including capitalizable implementation costs associated with hosting arrangements that are service contracts. Amortization, computed on the straight-line method, is charged to software expense in the Consolidated Statements of Comprehensive Income over the estimated useful life of the software, generally 5 years, or the term of the hosting arrangement for implementation costs related to service contracts.

        Cloud computing arrangements include software as a service (SaaS), platform as a service (PaaS), infrastructure as a service (IaaS) and other similar hosting arrangements. The Corporation primarily utilizes SaaS and IaaS arrangements.

        Capitalized implementation costs of hosting arrangements that are service contracts were insignificant for the three- and six-month periods ended June 30, 2020.

Reference Rate Reform

        In March 2020, the Financial Accounting Standards Board (FASB) issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” (ASU 2020-04), to provide temporary optional guidance to ease the potential accounting burden of reference rate reform. ASU 2020-04 is effective for eligible contract modifications from January 1, 2020 through December 31, 2022. Approximately 72 percent of the Corporation’s loans at June 30, 2020 were tied to the London Interbank Offered Rate (LIBOR). The Corporation uses interest rate swaps to convert variable-LIBOR rate loans to fixed rates for approximately 11 percent of the loan portfolio. Additional contracts with exposure to LIBOR include swaps converting fixed-rate long-term debt to variable LIBOR rates. The Corporation adopted the provisions of ASU 2020-04 for loan contract modifications as of January 1, 2020 and for all existing hedging relationships as of that date or entered into in the first quarter of 2020.

NOTE 2 – FAIR VALUE MEASUREMENTS

The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Corporation uses present value techniques and other valuation methods to estimate the fair values of its financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.

Investment securities available-for-sale, derivatives, deferred compensation plans and equity securities with readily determinable fair values (primarily money market mutual funds) are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as nonaccrual loans and loans classified as TDRs, other real estate (primarily foreclosed property), nonmarketable equity securities and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve write-downs of individual assets or application of lower of cost or fair value accounting.

Refer to Note 1 to the consolidated financial statements in the Corporation's Annual Report on Form 10-K for the year ended December 31, 2019 for further information about the fair value hierarchy, descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis.

Assets and Liabilities at Fair Value on a Nonrecurring Basis

The Corporation may be required to record certain assets and liabilities at fair value on a nonrecurring basis. These include assets that are recorded at the lower of cost or fair value, and were recognized at fair value since it was less than cost at the end of the period.

The following table presents assets recorded at fair value on a nonrecurring basis at June 30, 2020 and December 31, 2019. No liabilities were recorded at fair value on a nonrecurring basis at June 30, 2020 and December 31, 2019.

(in millions)															Level 3
June 30, 2020
Loans:
Commercial															$	146
Total assets at fair value															$	146
December 31, 2019
Loans:
Commercial															$	70
Total assets at fair value															$	70

Level 3 assets recorded at fair value on a nonrecurring basis at June 30, 2020 and December 31, 2019 included both nonaccrual loans and TDRs for which a specific allowance was established based on the fair value of collateral. The unobservable inputs were the additional adjustments applied by management to the appraised values to reflect such factors as non-current appraisals and revisions to estimated time to sell. These adjustments are determined based on qualitative judgments made by management on a case-by-case basis and are not quantifiable inputs, although they are used in the determination of fair value.

Estimated Fair Values of Financial Instruments Not Recorded at Fair Value on a Recurring Basis

The Corporation typically holds the majority of its financial instruments until maturity and thus does not expect to realize many of the estimated fair value amounts disclosed. The disclosures also do not include estimated fair value amounts for items that are not defined as financial instruments, but which have significant value. These include such items as core deposit intangibles, the future earnings potential of significant customer relationships and the value of trust operations and other fee generating businesses. The Corporation believes the imprecision of an estimate could be significant.

(a)Issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises.

Unrealized losses resulted from changes in market interest rates and liquidity. The Corporation’s portfolio is comprised of securities issued or guaranteed by the U.S. government or government-sponsored enterprises. As such, it is expected that the securities would not be settled at a price less than the amortized cost of the investments. Further, the Corporation does not intend to sell the investments, and it is not more likely than not that it will be required to sell the investments before recovery of amortized costs.

Interest receivable on investment securities totaled $19 million at June 30, 2020 and $20 million at December 31, 2019 and was included in accrued income and other assets on the Consolidated Balance Sheets.

Sales, calls and write-downs of investment securities available-for-sale resulted in the following gains and losses recorded in net securities gains (losses) on the Consolidated Statements of Comprehensive Income, computed based on the adjusted cost of the specific security.

The following table summarizes the amortized cost and fair values of debt securities by contractual maturity. Securities with multiple maturity dates are classified in the period of final maturity. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

(in millions)
June 30, 2020			Amortized Cost						Fair Value
Contractual maturity
Within one year			$	780					$	796
After one year through five years			2,115						2,212
After five years through ten years			872						898
After ten years			8,621						8,853
Total investment securities			$	12,388					$	12,759

Included in the contractual maturity distribution in the table above were residential mortgage-backed securities with a total amortized cost of $9.6 billion and a fair value of $9.9 billion. The actual cash flows of mortgage-backed securities may differ as borrowers of the underlying loans may exercise prepayment options.

At June 30, 2020, investment securities with a carrying value of $5.7 billion were pledged where permitted or required by law, including $5.2 billion pledged to the Federal Home Loan Bank (FHLB) as collateral for potential future borrowings of approximately $5.0 billion and $506 million to secure $432 million of liabilities, primarily public and other deposits of state and local government agencies as well as derivative instruments. For information on FHLB borrowings, refer to Note 7.

(a)Includes all loans not included in the categories of special mention, substandard or nonaccrual.

(b)Includes $3.8 billion of Small Business Administration Paycheck Protection Program (PPP) loans at June 30, 2020.

(c)Includes loans with an internal rating of special mention, substandard loans for which the accrual of interest has not been discontinued and nonaccrual loans. Special mention loans have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. Accruing substandard loans have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans are also distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies - on page F-51 in the Corporation's 2019 Annual Report. These categories are generally consistent with the "special mention" and "substandard" categories as defined by regulatory authorities. A minority of nonaccrual loans are consistent with the "doubtful" category.

Loan interest receivable totaled $132 million and $172 million at June 30, 2020 and December 31, 2019, respectively, and was included in accrued income and other assets on the Consolidated Balance Sheets.

Troubled Debt Restructurings

The following table details the amortized cost basis at June 30, 2020 and 2019 of loans considered to be TDRs that were restructured during the three- and six-month periods ended June 30, 2020 and 2019, by type of modification. In cases of loans with more than one type of modification, the loans were categorized based on the most significant modification.

			2020																		2019

(a)Primarily represents loan balances where terms were extended by more than an insignificant time period, typically more than 180 days, at or above contractual interest rates. Also includes commercial loans restructured in bankruptcy.

(b)Includes bankruptcy loans for which the court has discharged the borrower's obligation and the borrower has not reaffirmed the debt.

(c)Primarily loans secured by owner-occupied real estate.

The Corporation charges interest on principal balances outstanding during deferral periods. Additionally, none of the modifications involved forgiveness of principal. At June 30, 2020 and December 31, 2019, commitments to lend additional funds to borrowers whose terms have been modified in TDRs totaled $2 million and $3 million, respectively. On an ongoing basis, the Corporation monitors the performance of modified loans to their restructured terms. The allowance for loan losses continues to be reassessed on the basis of an individual evaluation of the loan.

For principal deferrals, incremental deterioration in the credit quality of the loan, represented by a downgrade in the risk rating of the loan, for example, due to missed interest payments or a reduction of collateral value, is considered a subsequent default. For interest rate reductions, a subsequent payment default is defined in terms of delinquency, when a principal or interest payment is 90 days past due. Of the TDRs modified during the twelve-month periods ended June 30, 2020 and 2019, principal deferrals totaled $6 million and $15 million in the three- and six-month periods ended June 30, 2020, respectively compared to none in the comparable periods in 2019. There were no subsequent defaults of interest rate reductions during either of the three- and six-month periods ended June 30, 2020 and 2019.

NOTE 5 - DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS

In the normal course of business, the Corporation enters into various transactions involving derivative and credit-related financial instruments to manage exposure to fluctuations in interest rate, foreign currency and other market risks and to meet the financing needs of customers (customer-initiated derivatives). These financial instruments involve, to varying degrees, elements of market and credit risk. Market and credit risk are included in the determination of fair value.

Market risk is the potential loss that may result from movements in interest rates, foreign currency exchange rates or energy commodity prices that cause an unfavorable change in the value of a financial instrument. The Corporation manages this risk by establishing monetary exposure limits and monitoring compliance with those limits. Market risk inherent in interest rate and energy contracts entered into on behalf of customers is mitigated by taking offsetting positions, except in those circumstances when the amount, tenor and/or contract rate level results in negligible economic risk, whereby the cost of purchasing an offsetting contract is not economically justifiable. The Corporation mitigates most of the inherent market risk in foreign exchange contracts entered into on behalf of customers by taking offsetting positions and manages the remainder through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and positions are monitored quarterly. Market risk inherent in derivative instruments held or issued for risk management purposes is typically offset by changes in the fair value of the assets or liabilities being hedged.

Credit risk is the possible loss that may occur in the event of nonperformance by the counterparty to a financial instrument. The Corporation attempts to minimize credit risk arising from customer-initiated derivatives by evaluating the creditworthiness of each customer, adhering to the same credit approval process used for traditional lending activities and obtaining collateral as deemed necessary. Derivatives with dealer counterparties are either cleared through a clearinghouse or settled directly with a single counterparty. For derivatives settled directly with dealer counterparties, the Corporation utilizes counterparty risk limits and monitoring procedures as well as master netting arrangements and bilateral collateral agreements to facilitate the management of credit risk. Master netting arrangements effectively reduce credit risk by permitting settlement of positive and negative positions and offset cash collateral held with the same counterparty on a net basis. Bilateral collateral agreements require daily exchange of cash or highly rated securities issued by the U.S. Treasury or other U.S. government entities to collateralize amounts due to either party. At June 30, 2020, counterparties with bilateral collateral agreements deposited $216 million of cash with the Corporation to secure the fair value of contracts in an unrealized gain position, and the Corporation had pledged $56 million of marketable investment securities and posted $30 million of cash as collateral for contracts in an unrealized loss position. For those counterparties not covered under bilateral collateral agreements, collateral is obtained, if deemed necessary, based on the results of management’s credit evaluation of the counterparty. Collateral varies, but may include cash, investment securities, accounts receivable, equipment or real estate. Included in the fair value of derivative instruments are credit valuation adjustments reflecting counterparty credit risk. These adjustments are determined by applying a credit spread for the counterparty or the Corporation, as appropriate, to the total expected exposure of the derivative. There were no derivative instruments with credit-risk-related contingent features that were in a liability position at June 30, 2020.

Derivative Instruments

Derivative instruments utilized by the Corporation are negotiated over-the-counter and primarily include swaps, caps and floors, forward contracts and options, each of which may relate to interest rates, energy commodity prices or foreign currency exchange rates. Swaps are agreements in which two parties periodically exchange cash payments based on specified indices applied to a specified notional amount until a stated maturity. Caps and floors are agreements which entitle the buyer to receive cash payments based on the difference between a specified reference rate or price and an agreed strike rate or price, applied to a specified notional amount until a stated maturity. Forward contracts are over-the-counter agreements to buy or sell an asset at a specified future date and price. Options are similar to forward contracts except the purchaser has the right, but not the obligation, to buy or sell the asset during a specified period or at a specified future date.

Over-the-counter contracts are tailored to meet the needs of the counterparties involved and, therefore, contain a greater degree of credit risk and liquidity risk than exchange-traded contracts, which have standardized terms and readily available price information. The Corporation reduces exposure to market and liquidity risks from over-the-counter derivative instruments entered into for risk management purposes, and transactions entered into to mitigate the market risk associated with customer-initiated transactions, by taking offsetting positions with investment grade domestic and foreign financial institutions and subjecting counterparties to credit approvals, limits and collateral monitoring procedures similar to those used in making other extensions of credit. In addition, certain derivative contracts executed bilaterally with a dealer counterparty in the over-the-counter market are cleared through a clearinghouse, whereby the clearinghouse becomes the counterparty to the transaction.

(b)Variable rates paid on receive fixed swaps designated as fair value hedges are based on one- and six-month LIBOR rates in effect at June 30, 2020 and December 31, 2019.

Foreign exchange rate risk arises from changes in the value of certain assets and liabilities denominated in foreign currencies. The Corporation employs spot and forward contracts in addition to swap contracts to manage exposure to these and other risks. These instruments are used as economic hedges, and net gains or losses are included in other noninterest income in the Consolidated Statements of Comprehensive Income.

Customer-Initiated and Other

The Corporation enters into derivative transactions at the request of customers and generally takes offsetting positions with dealer counterparties to mitigate the inherent market risk. Income primarily results from the spread between the customer derivative and the offsetting dealer position.

For customer-initiated foreign exchange contracts where offsetting positions have not been taken, the Corporation manages the remaining inherent market risk through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and reviewed quarterly. For those customer-initiated derivative contracts which were not offset or where the Corporation holds a position within the limits described above, the Corporation recognized no significant gains or losses in other noninterest income in the Consolidated Statements of Comprehensive Income for both the three- and six-month periods ended June 30, 2020 and 2019.

Fair values of customer-initiated and other derivative instruments represent the net unrealized gains or losses on such contracts and are recorded in the Consolidated Balance Sheets. Changes in fair value are recognized in the Consolidated Statements of Comprehensive Income. The net gains recognized in income on customer-initiated derivative instruments, net of the impact of offsetting positions, were as follows.

									Three Months Ended June 30,																		Six Months Ended June 30,
(in millions)						Location of Gain			2020						2019						2020						2019
Interest rate contracts						Other noninterest income			$	8					$	6					$	16					$	12

Credit-Related Financial Instruments

The Corporation issues off-balance sheet financial instruments in connection with commercial and consumer lending activities. The Corporation’s credit risk associated with these instruments is represented by the contractual amounts indicated in the following table.

(in millions)			June 30, 2020						December 31, 2019
Unused commitments to extend credit:
Commercial and other			$	22,588					$	23,681
Bankcard, revolving check credit and home equity loan commitments			3,275						3,180
Total unused commitments to extend credit			$	25,863					$	26,861
Standby letters of credit			$	3,185					$	3,320
Commercial letters of credit			19						18

The Corporation maintains an allowance to cover current expected credit losses on lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. The allowance for credit losses on lending-related commitments, included in accrued expenses and other liabilities on the Consolidated Balance Sheets, was $59 million and $31 million at June 30, 2020 and December 31, 2019, respectively.

Unused Commitments to Extend Credit

Commitments to extend credit are legally binding agreements to lend to a customer, provided there is no violation of any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments expire without being drawn upon, the total contractual amount of commitments does not necessarily represent future cash requirements of the Corporation. Commercial and other unused commitments are primarily variable rate commitments. The allowance for credit losses on lending-related commitments included $47 million at June 30, 2020 and $25 million at December 31, 2019 for current expected credit losses on the Corporation’s unused commitments to extend credit.

Standby and Commercial Letters of Credit

Standby letters of credit represent conditional obligations of the Corporation which guarantee the performance of a customer to a third party. Standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Commercial letters of credit are issued to finance foreign or domestic trade transactions. These contracts expire in decreasing amounts through the year 2028. The Corporation may enter

into participation arrangements with third parties that effectively reduce the maximum amount of future payments which may be required under standby and commercial letters of credit. These risk participations covered $163 million and $161 million, respectively, of the $3.2 billion and $3.3 billion standby and commercial letters of credit outstanding at June 30, 2020 and December 31, 2019, respectively.

The carrying value of the Corporation’s standby and commercial letters of credit, included in accrued expenses and other liabilities on the Consolidated Balance Sheets, totaled $34 million at June 30, 2020, including $22 million in deferred fees and $12 million in the allowance for credit losses on lending-related commitments. At December 31, 2019, the comparable amounts were $32 million, $26 million and $6 million, respectively.

The following table presents a summary of criticized standby and commercial letters of credit at June 30, 2020 and December 31, 2019. The Corporation's criticized list is generally consistent with the Special Mention, Substandard and Doubtful categories defined by regulatory authorities. The Corporation manages credit risk through underwriting, periodically reviewing and approving its credit exposures using Board committee approved credit policies and guidelines.

(dollar amounts in millions)			June 30, 2020						December 31, 2019

Other Credit-Related Financial Instruments

The Corporation enters into credit risk participation agreements, under which the Corporation assumes credit exposure associated with a borrower’s performance related to certain interest rate derivative contracts. The Corporation is not a party to the interest rate derivative contracts and only enters into these credit risk participation agreements in instances in which the Corporation is also a party to the related loan participation agreements for such borrowers. The Corporation manages credit risk on credit risk participation agreements by monitoring the creditworthiness of the borrowers, based on the normal credit review process as if the Corporation had entered into the derivative instruments directly with the borrowers. The notional amount of such credit risk participation agreements reflects the pro-rata share of the derivative instrument, consistent with the Corporation's share of the related participated loan. As of June 30, 2020 and December 31, 2019, the total notional amount of the credit risk participation agreements was approximately $1.1 billion and $786 million, respectively, and the fair value was $3 million at June 30, 2020 and insignificant at December 31, 2019. The maximum estimated exposure to these agreements, as measured by projecting a maximum value of the guaranteed derivative instruments, assuming 100 percent default by all obligors on the maximum values, was $76 million and $20 million at June 30, 2020 and December 31, 2019, respectively. In the event of default, the lead bank has the ability to liquidate the assets of the borrower, in which case the lead bank would be required to return a percentage of the recouped assets to the participating banks. As of June 30, 2020, the weighted average remaining maturity of outstanding credit risk participation agreements was 4.7 years.

NOTE 6 - VARIABLE INTEREST ENTITIES (VIEs)

The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE and whether the Corporation is the primary beneficiary and should consolidate the entity based on the variable interests it held both at inception and when there is a change in circumstances that requires a reconsideration.

The Corporation holds ownership interests in funds in the form of limited partnerships or limited liability companies (LLCs) investing in affordable housing projects that qualify for the low-income housing tax credit (LIHTC). The Corporation also directly invests in limited partnerships and LLCs which invest in community development projects, which generate similar tax credits to investors (other tax credit entities). As an investor, the Corporation obtains income tax credits and deductions from the operating losses of these tax credit entities. These tax credit entities meet the definition of a VIE; however, the Corporation is not the primary beneficiary of the entities, as the general partner or the managing member has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entities.

The Corporation accounts for its interests in LIHTC entities using the proportional amortization method. Ownership interests in other tax credit entities are accounted for under either the cost or equity method. Exposure to loss as a result of the Corporation's involvement in LIHTC entities and other tax credit entities at June 30, 2020 was limited to $451 million and $10 million, respectively.

Investment balances, including all legally binding commitments to fund future investments, are included in accrued income and other assets on the Consolidated Balance Sheets. A liability is recognized in accrued expenses and other liabilities

on the Consolidated Balance Sheets for all legally binding unfunded commitments to fund tax credit entities ($173 million at June 30, 2020). Amortization and other write-downs of LIHTC investments are presented on a net basis as a component of the provision for income taxes on the Consolidated Statements of Comprehensive Income, while amortization and write-downs of other tax credit investments are recorded in other noninterest income. The income tax credits and deductions are recorded as a reduction of income tax expense and a reduction of federal income taxes payable.

The Corporation provided no financial or other support that was not contractually required to any of the above VIEs during the six months ended June 30, 2020 and 2019.

The following table summarizes the impact of these tax credit entities on the Corporation’s Consolidated Statements of Comprehensive Income.

the FHLB advances resets between four and eight weeks, based on the FHLB auction rate. At June 30, 2020, the weighted-average rate on the FHLB advances was 0.31%. Each note may be prepaid in full, without penalty, at each scheduled reset date. Borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At June 30, 2020, $18.3 billion of real estate-related loans and $5.2 billion of investment securities were pledged to the FHLB as collateral for outstanding short- and long-term advances of $750 million and $3.6 billion, respectively, with an additional capacity for potential future borrowings of approximately $10.1 billion.

        Unamortized debt issuance costs deducted from the carrying amount of medium- and long-term debt totaled $11 million at June 30, 2020 and $12 million at December 31, 2019.

In May 2020, the Corporation issued and sold 400,000 depositary shares, each representing a 1/100th ownership interest in a share of 5.625% Fixed-Rate Reset Non-Cumulative Perpetual Preferred Stock, Series A, without par value, with a liquidation preference of $100,000 per share (equivalent of $1,000 per depositary share). Holders of the depositary shares will be entitled to all proportional rights and preferences of the Series A preferred stock (including dividend, voting, redemption and liquidation rights). The $400 million issuance yielded $395 million in proceeds net of underwriting discounts and offering expenses. Dividends on the Series A preferred stock will accrue on a non-cumulative basis and will be payable in arrears when, as and if authorized by the Corporation’s board of directors or a duly authorized committee of the board and declared by the Corporation, on the first day of January, April, July, and October of each year, commencing on October 1, 2020. Under the terms of the Series A preferred stock, the ability of the Corporation to pay dividends on, make distributions with respect to, or to repurchase, redeem or acquire its common stock or any other stock ranking on parity with or junior to the Series A preferred stock, is subject to restrictions in the event that the Corporation does not declare and either pay or set aside a sum sufficient for payment of dividends on the Series A Preferred Stock for the immediately preceding dividend period. The Series A preferred stock is perpetual and has no maturity date, but is redeemable at specified times subject to regulatory considerations.

NOTE 11 - INCOME TAXES AND TAX-RELATED ITEMS

At June 30, 2020, net unrecognized tax benefits were $18 million, compared to $17 million at December 31, 2019. The Corporation anticipates that it is reasonably possible that final settlement of federal and state tax issues will result in a decrease in net unrecognized tax benefits of $1 million within the next twelve months. Included in accrued expenses and other liabilities on the Consolidated Balance Sheets was a liability for tax-related interest and penalties of $6 million and $8 million on June 30, 2020 and December 31, 2019, respectively.

Net deferred tax assets were $11 million at June 30, 2020, compared to $42 million at December 31, 2019, primarily driven by increases to deferred tax liabilities related to unrealized losses on investment securities available-for-sale and net hedging gains, partially offset by increases to deferred tax assets related to the allowance for loan losses and allowance for depreciation. Included in deferred tax assets at both June 30, 2020 and December 31, 2019 were $3 million of state net operating loss carryforwards, which expire between 2020 and 2029. The Corporation believes that it is more likely than not that the benefit from certain of these state net operating loss carryforwards will not be realized and, accordingly, maintained a valuation allowance of $3 million at both June 30, 2020 and December 31, 2019. The determination regarding valuation allowance was based on evidence of loss carryback capacity, projected future reversals of existing taxable temporary differences to absorb the deferred tax assets and assumptions made regarding future events.

In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) or other tax jurisdictions may review and/or challenge specific interpretive tax

positions taken by the Corporation with respect to those transactions. The Corporation believes its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The IRS or other tax jurisdictions, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law.

Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that current tax reserves are adequate, and the amount of any potential incremental liability arising is not expected to have a material adverse effect on the Corporation’s consolidated financial condition or results of operations. Probabilities and outcomes are reviewed as events unfold, and adjustments to the reserves are made when necessary.

NOTE 12 - CONTINGENT LIABILITIES

Legal Proceedings

As previously reported in the Corporation's Form 10-K for the year ended December 31, 2019 and Form 10-Q for the period ended March 31, 2020, Comerica Bank, a wholly-owned subsidiary of the Corporation, was named in November 2011 as a third-party defendant in Butte Local Development v. Masters Group v. Comerica Bank (the case), for lender liability. The case was initially tried in January 2014, in the Montana Second District Judicial Court for Silver Bow County in Butte, Montana. On January 17, 2014, a jury found for Masters, resulting in an award against the Bank. On July 1, 2015, after an appeal filed by the Bank, the Montana Supreme Court reversed the judgment against the Bank and remanded the case for a new trial with instructions that Michigan contract law should apply and dismissing all other claims. In January 2017, the case was retried, without a jury, in the Second District Court, Silver Bow County, Montana. In November 2019, the court found the Bank breached its forbearance agreement. On January 17, 2020, the court conducted a hearing on the amount of costs and interest that Masters is entitled to recover. On June 12, 2020, the court found Masters is entitled to attorneys' fees, interest and costs. The Bank is considering its options, including additional appeals. Management believes that current reserves related to this case are adequate in the event of an adverse outcome.

The Corporation and certain of its subsidiaries are subject to various other pending or threatened legal proceedings arising out of the normal course of business or operations. The Corporation believes it has meritorious defenses to the claims asserted against it in its other currently outstanding legal proceedings and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interests of the Corporation and its shareholders. Settlement may result from the Corporation's determination that it may be more prudent financially to settle, rather than litigate, and should not be regarded as an admission of liability. On at least a quarterly basis, the Corporation assesses its potential liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. On a case-by-case basis, reserves are established for those legal claims for which it is probable that a loss will be incurred either as a result of a settlement or judgment, and the amount of such loss can be reasonably estimated. The actual costs of resolving these claims may be substantially higher or lower than the amounts reserved. Based on current knowledge, and after consultation with legal counsel, management believes current reserves are adequate, and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the Corporation’s consolidated financial condition, results of operations or cash flows. Legal fees of $5 million and $4 million were included in other noninterest expenses on the Consolidated Statements of Comprehensive Income for the three-month periods ended June 30, 2020 and 2019, respectively, and $7 million and $5 million for the six-month periods ended June 30, 2020 and 2019, respectively.

For matters where a loss is not probable, the Corporation has not established legal reserves. The Corporation believes the estimate of the aggregate range of reasonably possible losses, in excess of reserves established, for all legal proceedings in which it is involved is from zero to approximately $46 million at June 30, 2020. This estimated aggregate range of reasonably possible losses is based upon currently available information for those proceedings in which the Corporation is involved, taking into account the Corporation’s best estimate of such losses for those cases for which such estimate can be made. For certain cases, the Corporation does not believe that an estimate can currently be made. The Corporation’s estimate involves significant judgment, given the varying stages of the proceedings (including the fact many are currently in preliminary stages), the existence in certain proceedings of multiple defendants (including the Corporation) whose share of liability has yet to be determined, the numerous yet-unresolved issues in many of the proceedings (including issues regarding class certification and the scope of many of the claims) and the attendant uncertainty of the various potential outcomes of such proceedings. Accordingly, the Corporation’s estimate will change from time to time, and actual losses may be more or less than the current estimate.

In the event of unexpected future developments, it is possible the ultimate resolution of these matters, if unfavorable, may be material to the Corporation's consolidated financial condition, results of operations or cash flows.

NOTE 13 - BUSINESS SEGMENT INFORMATION

The Corporation has strategically aligned its operations into three major business segments: the Commercial Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. Business segment results are produced by the Corporation’s internal management accounting system. This system measures financial results based on the internal business unit structure of the Corporation. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. The management accounting system assigns balance sheet and income statement items to each business segment using certain methodologies, which are regularly reviewed and refined. From time to time, the Corporation may make reclassifications among the segments to more appropriately reflect management's current view of the segments, and methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines. For comparability purposes, amounts in all periods are based on business unit structure and methodologies in effect at June 30, 2020.

The following discussion provides information about the activities of each business segment. A discussion of the financial results and the factors impacting performance can be found in the section entitled "Business Segments" in the financial review.

The Commercial Bank meets the needs of small and middle market businesses, multinational corporations and governmental entities by offering various products and services including commercial loans and lines of credit, deposits, cash management, capital market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services.

The Retail Bank includes a full range of personal financial services, consisting of consumer lending, consumer deposit gathering and mortgage loan origination. This business segment offers a variety of consumer products including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit and residential mortgage loans.

Wealth Management offers products and services consisting of fiduciary services, private banking, retirement services, investment management and advisory services, investment banking and brokerage services. This business segment also offers the sale of annuity products, as well as life, disability and long-term care insurance products.

The Finance segment includes the Corporation’s securities portfolio and asset and liability management activities. This segment is responsible for managing the Corporation’s funding, liquidity and capital needs, performing interest sensitivity analysis and executing various strategies to manage the Corporation’s exposure to liquidity, interest rate risk and foreign exchange risk.

The Other category includes the income and expense impact of equity and cash, tax benefits not assigned to specific business segments, charges of an unusual or infrequent nature that are not reflective of the normal operations of the business segments and miscellaneous other expenses of a corporate nature.

For further information on the methodologies which form the basis for these results refer to Note 22 to the consolidated financial statements in the Corporation's 2019 Annual Report.

SERVING CUSTOMERS, COLLEAGUES AND COMMUNITIES DURING THE COVID-19 PANDEMIC

        The COVID-19 outbreak has affected countless people world-wide and continues to negatively impact the global economy. While the full effects of the pandemic remain unknown, the Corporation is committed to supporting its customers, colleagues and communities during this difficult time. The Corporation offers hardship relief assistance to customers, including the consideration of various loan payment deferral and fee waiver options, and encourages customers to reach out for assistance to support their individual circumstances. As a Small Business Administration preferred lender, the Corporation was well positioned to assist business customers in accessing funds available through the Paycheck Protection Program (PPP) and other lending initiatives. Through June 30, 2020, the Corporation funded $3.9 billion of PPP loans, granted payment deferrals for $4.5 billion in loans (primarily commercial), including $57 million of loans on their second deferral, and waived overdraft, late payment, ATM and other customer fees. The Corporation has continued to serve customers at banking center drive-throughs and offer lobby hours by appointment while adhering to social distancing standards.

        In response to the pandemic, the Corporation activated its disaster recovery protocol, successfully avoiding significant disruptions to internal and external functions. The Corporation has supported colleagues through additional compensation and benefits to those most impacted by the pandemic, as well as awarded bonuses for extraordinary service in support of the PPP process.

        The Corporation and the Comerica Charitable Foundation have pledged $8 million to support business needs and community service organizations that care for and provide critical services to our communities.

OUTLOOK FOR THIRD QUARTER 2020 COMPARED TO SECOND QUARTER 2020

Based on current management expectations for recessionary conditions:

•Decline in average loans reflects lending to small businesses with a full quarter benefit of PPP, more than offset by decreases in Mortgage Banker Finance, Large Corporate and National Dealer Services.

•Average deposits relatively stable as customers utilize economic stimulus proceeds.

•Decrease in net interest income resulting from a $10 million to $15 million net impact of lower interest rates (assumes one-month London Interbank Offered Rate (LIBOR) of 17 basis points and interest-bearing deposit cost of 20 basis points). Lower loan balances expected to be offset by lower wholesale debt and one additional day.

•Provision for credit losses reflective of economic environment, including the effects resulting from the duration and severity of the COVID-19 pandemic.

•Decline in noninterest income due to reduced card fees related to transaction activity and lower market-based investment banking and derivative fees, partially offset by higher service charges on deposit accounts due to increased activity. Higher securities trading income and deferred compensation levels in second quarter 2020 not expected to repeat.

•Increase in noninterest expenses, reflecting technology and occupancy projects as well as higher charitable contributions and seasonal impacts of marketing and staff insurance expenses, mostly offset by continued expense discipline and reduction in COVID-19-related costs.

•Capital reflects declaration of first preferred stock dividend and a focus on supporting customers' financing needs, as well as maintaining an attractive common dividend.

RESULTS OF OPERATIONS

Net income for the three months ended June 30, 2020 was $113 million, a decrease of $185 million compared to $298 million for the three months ended June 30, 2019. The decrease in net income reflected the net impact of lower short-term rates. Results for the three months ended June 30, 2020 were also impacted by an increase in the provision for credit losses, calculated using the current expected credit loss (CECL) model, which continues to reflect the forecasted impact of the COVID-19 pandemic and continued pressures on the Energy portfolio. Net income for the six months ended June 30, 2020 was $48 million, a decrease of $589 million compared to $637 million for the six months ended June 30, 2019. The decrease in net income was driven by an increase in the provision for credit losses as well as the net impact of lower short-term rates.

Net income per diluted common share was $0.80 and $1.94 for the three months ended June 30, 2020 and 2019, respectively, a decrease of $1.14 per diluted common share. Net income per diluted common share was $0.34 and $4.06 for the six months ended June 30, 2020 and 2019, respectively, a decrease of $3.72 per diluted common share.

Net interest income was $471 million for the three months ended June 30, 2020, a decrease of $132 million compared to $603 million for the three months ended June 30, 2019. The decrease in net interest income primarily reflected the impact of lower short-term rates partially offset by the impact of a $2.5 billion increase in average loans, primarily PPP loans. The decline in rates led to the 116 basis point decrease in the net interest margin, to 2.50 percent for the three months ended June 30, 2020 from 3.66 percent for the three months ended June 30, 2019.

Provision for Credit Losses

        The provision for credit losses, which includes the provision for loan losses and the provision for credit losses on lending-related commitments, was $138 million for the three months ended June 30, 2020, compared to $44 million for the three months ended June 30, 2019. The provision for credit losses for the three months ended June 30, 2020, which was calculated under the CECL model, increased primarily due to the forecasted impact of the COVID-19 pandemic, including the economic impacts of social distancing, and sustained pressures on the Energy portfolio. Net loan charge-offs increased $17 million to $50 million, or 0.37 percent of average total loans for the three months ended June 30, 2020, compared to $33 million, or 0.26 percent of average total loans for the three months ended June 30, 2019. The increase was driven by a $20 million increase in net charge-offs of Energy loans.

        An analysis of the allowance for credit losses and a summary of nonperforming assets are presented under the "Credit Risk" subheading in the "Risk Management" section of this financial review. Further information about the adoption of CECL, which resulted in a $17 million decrease to the allowance for credit losses as of January 1, 2020, is presented in Note 1 to the consolidated financial statements.

Noninterest expenses increased $16 million to $440 million. Excluding the $8 million classification adjustment for the prospective adoption of ASU No. 2018-15, the increase in noninterest expenses primarily reflected higher outside processing fee expense, salaries and benefits expense and software expense. The increase in salaries and benefits expense was driven by annual merit increases and the payment of COVID-19-related stipends, partially offset by lower technology-related labor costs.

Provision for Credit Losses

The provision for credit losses, which includes both the provision for loan losses and the provision for credit losses on lending-related commitments, was $549 million for the six months ended June 30, 2020, compared to $31 million for the six months ended June 30, 2019. The provision for credit losses for the six months ended June 30, 2020, which was calculated under the CECL model, increased primarily due to the forecasted impact of the COVID-19 pandemic, including the economic impacts of social distancing, and sustained pressures on the Energy portfolio. Net loan charge-offs increased $90 million to $134 million for the six months ended June 30, 2020, compared to $44 million for the six months ended June 30, 2019, driven by a $79 million increase in net charge-offs of Energy loans.

Noninterest expenses increased $8 million to $865 million. Excluding the $15 million classification adjustment for the prospective adoption of ASU No. 2018-15, the increase in noninterest expenses primarily reflected higher operational losses (included in other noninterest expenses), outside processing fee expense and FDIC insurance expense, partially offset by a decrease in salaries and benefits expense. The decline in salaries and benefits expense included lower incentive and annual stock-based compensation, as well as a reduction in technology-related contingent labor costs, partially offset by annual merit increases and the payment of COVID-19-related stipends.

STRATEGIC LINES OF BUSINESS AND MARKETS

The Corporation has strategically aligned its operations into three major business segments: the Commercial Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. The Other category includes items not directly associated with these business segments or the Finance segment. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. Market segment results are also provided for the Corporation's three primary geographic markets: Michigan, California and Texas. In addition to the three primary geographic markets, Other Markets is also reported as a market segment. Note 13 to the consolidated financial statements describes the business activities of each business segment and presents financial results of the business and market segments for the three- and six-month periods ended June 30, 2020 and 2019.

The Corporation's management accounting system assigns balance sheet and income statement items to each segment using certain methodologies, which are regularly reviewed and refined. These methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines. Note 22 to

Table of Contents

the consolidated financial statements in the Corporation's 2019 Annual Report describes the Corporation's segment reporting methodology.

Net interest income for each segment reflects the interest income generated by earning assets less interest expense on interest-bearing liabilities plus the net impact from associated internal funds transfer pricing (FTP). The FTP methodology allocates credits to each business segment for deposits and other funds provided as well as charges for loans and other assets being funded. FTP crediting rates for deposits and other funds provided reflect the long-term value of deposits and other funding sources based on their implied maturities. FTP charge rates for funding loans and other assets reflect a matched cost of funds based on the pricing and duration characteristics of the assets. Therefore, net interest income for each segment primarily reflects the volume and associated FTP impacts of loan and deposit levels. As overall interest rates decreased, business segments, particularly those focused on generating deposits, were impacted by lower FTP crediting rates on deposits in the six months ended June 30, 2020 compared to the same period in the prior year. Similarly, FTP charges for funding loans decreased in the six months ended June 30, 2020, compared to the same period in the prior year.

The Commercial Bank's net income decreased $400 million to $112 million. Net interest income decreased $50 million to $782 million, due to a $293 million decrease in loan interest income, partially offset by decreases of $220 million in allocated net FTP charges and $23 million in deposit costs. The provision for credit losses increased $467 million to $513 million primarily due to the forecasted impact of the COVID-19 pandemic, including the economic impacts of social distancing and sustained pressures on the Energy portfolio, while net credit-related charge-offs increased $84 million to $131 million, primarily due to Energy net charge-offs of $112 million. Noninterest income was stable, while noninterest expenses increased $8 million, primarily reflecting a $4 million increase in transfer charges as well as higher operational losses, legal fees and outside processing fee expense, partially offset by lower incentive and stock-based compensation.

FINANCIAL CONDITION

Second Quarter 2020 Compared to Fourth Quarter 2019

Period-End Balances

Total assets increased $11.0 billion to $84.4 billion, primarily due to increases of $7.4 billion in interest-bearing deposits with banks and $3.1 billion in loans. The growth in interest-bearing deposits with banks (primarily deposits with the Federal Reserve Bank) resulted from increased liquidity in the banking system from stimulus programs. The increase in loans reflected growth in Mortgage Banker Finance due to seasonality and elevated refinancing activity as well as increases in Business Banking, Commercial Real Estate, general Middle Market, Retail Banking (small businesses) and Corporate Banking, partially offset by decreases in National Dealer Services and Equity Fund Services. At June 30, 2020, PPP loans totaled $3.8 billion, driving the growth in general Middle Market, Business Banking and Retail Banking (small businesses).

Total liabilities increased $10.5 billion to $76.6 billion, reflecting increases of $8.2 billion and $2.2 billion in noninterest-bearing and interest-bearing deposits, respectively, as customers conserved liquidity as described in the asset discussion above. Total shareholders' equity increased $475 million, including net proceeds of $395 million from the issuance of preferred stock in May 2020.

Average Balances

Total assets increased $8.5 billion to $81.6 billion, primarily due to increases of $4.9 billion in interest-bearing deposits with banks and $3.0 billion in loans. The following table provides information about the change in the Corporation's average loan portfolio by loan type and geographic market.

(a)Includes PPP loans of $2.6 billion for the three months ended June 30, 2020.

The increase in loans reflected growth in Corporate Banking, Commercial Real Estate, general Middle Market, Mortgage Banker Finance (due to seasonality and elevated refinancing activity) and Business Banking, partially offset by a decrease in National Dealer Services and Energy. The average balance of PPP loans for the three months ended June 30, 2020 was $2.6 billion, driving the growth in general Middle Market and Business Banking.

Total liabilities increased $8.1 billion to $74.1 billion, reflecting increases of $5.7 billion and $1.4 billion in noninterest-bearing and interest-bearing deposits, respectively. Total shareholders' equity increased $355 million to $7.6 billion, resulting primarily from the same reasons as described in the period-end discussion above.

(b)Includes approximately 101,000 shares purchased pursuant to deferred compensation plans and shares purchased from employees to pay for taxes related to restricted stock vesting under the terms of an employee share-based compensation plan during the six months ended June 30, 2020. These transactions are not considered part of the Corporation's repurchase program.

In March 2020, the Corporation suspended its share repurchase program, with a focus on deploying capital to meet customers' growing financing requirements, resulting in no share repurchases under the program during second quarter 2020. The Corporation will continue to assess the resumption of repurchases subject to various factors including financial performance, capital needs and market conditions. Since its inception in 2010, a total of 87.2 million shares have been authorized for repurchase. There is no expiration date for the share repurchase program.

In May 2020, the Corporation issued $400 million of 5.625% non-cumulative perpetual preferred stock, which yielded $395 million in proceeds net of underwriting discounts and offering expenses. See Note 9 to the consolidated financial statements for further information about the terms of the preferred stock.

        The Corporation is prepared to continue using capital and liquidity in a responsible way to assist customers impacted by the COVID-19 crisis with a target of attaining and maintaining a Common Equity Tier 1 (CET1) capital ratio of approximately 10 percent. At June 30, 2020, the Corporation's estimated CET1 capital ratio was 9.97 percent, a decrease of 16 thousand basis points compared to December 31, 2019. In 2020, the Corporation elected regulatory relief to defer the impact of adopting the CECL model for measuring credit losses on regulatory capital, which resulted in a cumulative 13-basis-point benefit to the estimated CET1 capital ratio at June 30, 2020. Also in 2020, the Corporation adopted capital rules issued by federal banking agencies that simplified certain regulatory capital rules, including the capital treatment of mortgage servicing assets, certain deferred tax assets, investments in the capital instruments of unconsolidated financial institutions and minority interests.

        The following table presents the minimum ratios required.

RISK MANAGEMENT

The following updated information should be read in conjunction with the "Risk Management" section on pages F-20 through F-33 in the Corporation's 2019 Annual Report.

Credit Risk

Allowance for Credit Losses

The allowance for credit losses includes both the allowance for loan losses and the allowance for credit losses on lending-related commitments. Effective January 1, 2020, the allowance for credit losses reflected the adoption of Topic 326, which requires companies to estimate credit losses using the CECL framework. As a percentage of total loans, the allowance for credit losses was 1.99 percent at June 30, 2020, compared to 1.33 percent at December 31, 2019. Excluding $3.8 billion in PPP loans, which are guaranteed by the Small Business Administration, the allowance for credit losses was 2.15 percent of total loans at June 30, 2020. The allowance for credit losses covered 3.9 times and 3.3 times total nonperforming loans at June 30, 2020 and December 31, 2019, respectively.

At adoption on January 1, 2020, the scope and severity of the economic crisis resulting from the eventual COVID-19 pandemic were unknown. As such, the economic scenario used by the Corporation to develop its estimate of CECL as of the adoption date reflected a continued moderate U.S. economic expansion compared to 2019 levels and a stable interest rate environment, with the federal funds rate remaining in the 1.50- to 1.75-percent range. Other assumptions included resolution of trade tensions, a calmer global economy and a strong U.S. dollar, all of which supported modest industrial production growth and stable oil prices. The economic scenario also assumed strong labor market conditions to support the consumer sector. Management also considered the level of uncertainty regarding its economic assumptions as part of the qualitative adjustment. The adoption of CECL resulted in a $17 million day-one decrease in the allowance for credit losses, from $668 million at December 31, 2019 under the incurred loss model. See Note 1 to the consolidated financial statements for further information about the adoption of CECL.

The allowance for credit losses increased by $415 million from adoption date to $1.1 billion at June 30, 2020, primarily reflecting the economic impacts of the COVID-19 pandemic and the response by domestic and global governmental authorities, including quarantines and other social distancing policies aimed at fighting the spread of the virus. Energy markets, which were experiencing already reduced capital market activity prior to the pandemic, showed continued stress through the first half of 2020. The U.S. economy contracted into a recession with unusual speed and force, ending the longest expansionary period in U.S. history. The U.S. government and the Federal Reserve responded to the pandemic with unprecedented measures. In addition to the Federal Reserve reducing the target federal funds rate to zero to 0.25 percent, Congress passed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) that included an estimated $2 trillion stimulus package. During second quarter 2020, states across the U.S. began loosening social distancing policies, stimulating economic activity. While economic conditions showed signs of improvement toward the end of the second quarter 2020, there continues to be uncertainty regarding the impact to the U.S. economy from a secondary wave of COVID-19 cases as jurisdictions begin to reopen across the country and the mitigating impacts of government intervention. These developments shaped the 2-year

reasonable and supportable forecast used by the Corporation in its calculation of the CECL estimate at June 30, 2020. After a sharp decline in GDP in second quarter 2020, the forecast reflects growth through the end of 2020, normalizing to historical growth rates by the end of the forecast period. Forecasts for other key economic variables, including the unemployment rate, oil prices and industrial production levels, are generally in line with GDP projections. Interest rates remain low, reflecting the Federal Reserve's expectation that rates will remain at current levels in the near-to mid-term, while corporate bond rates reflect decreasing default risk as the economy recovers. The following table summarizes the forecasts for the economic variables most impactful to the allowance for credit losses estimate at June 30, 2020.

Economic Variable			Base Forecast
Real GDP growth			Grows by 24 percent in third quarter 2020, normalizing into a long-term growth rate of 2 percent by the end of the forecast period.
Unemployment rate			Remaining above 10 percent through third quarter 2020, gradually decreasing to 7 percent by the end of the forecast period.
Corporate BBB bond to 10-year Treasury bond spreads			Third quarter 2020 spread of 3 percent reflects residual impacts of economic uncertainty, followed by a sharp, short-term decline then normalizing to a rate of 2 percent by the end of the forecast period.
Oil Prices			Prices below $30 per barrel in third quarter, increase in line with GDP through the forecast period, stabilizing at $50 per barrel by first quarter 2022.

Due to the high degree of uncertainty regarding the ultimate economic consequences of the pandemic, as well as the effectiveness of the government's stimulus packages, management also considered other economic scenarios to make appropriate qualitative adjustments for certain sectors of its lending portfolio, including more benign and more severe forecasts.

Allowance for Loan Losses

The allowance for loan losses represents management’s estimates of current expected credit losses in the Corporation’s loan portfolio. Pools of loans with similar risk characteristics are collectively evaluated, while loans that no longer share risk characteristics with loan pools are evaluated individually.

Collective loss estimates are determined by applying reserve factors, designed to estimate current expected credit losses, to amortized cost balances over the remaining contractual life of the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools. The allowance for loan losses also includes qualitative adjustments to bring the allowance to the level management believes is appropriate based on factors that have not otherwise been fully accounted for, including adjustments for foresight risk, input imprecisions and model imprecision. Credit losses for loans that no longer share risk characteristics with the loan pools are estimated on an individual basis. Individual credit loss estimates are typically performed for nonaccrual loans and modified loans classified as TDRs and are based on one of several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected cash flows. 

As a percentage of total loans, the allowance for loan losses was 1.88 percent at June 30, 2020, compared to 1.27 percent at December 31, 2019. Excluding PPP loans, the allowance for loan losses was 2.03 percent of total loans at June 30, 2020. The allocation of reserves for Energy loans remains above 10 percent in response to sustained pressures on the Energy portfolio. Nonperforming loans were 0.51 percent of total loans at June 30, 2020, compared to 0.40 percent at December 31, 2019, and the allowance covered 3.7 times and 3.1 times total nonperforming loans at June 30, 2020 and December 31, 2019, respectively.

Allowance for Credit Losses on Lending-Related Commitments

        The allowance for credit losses on lending-related commitments estimates current expected credit losses on collective pools of letters of credit and unused commitments to extend credit based on reserve factors, determined in a manner similar to business loans, multiplied by a probability of draw estimate based on historical experience and credit risk, applied to commitment amounts. The allowance for credit losses on lending-related commitments totaled $59 million and $31 million at June 30, 2020 and December 31, 2019, respectively.

        For additional information regarding the allowance for credit losses, refer to the "Critical Accounting Policies" section and Note 1 to the consolidated financial statements.

Nonperforming Assets

Nonperforming assets include loans on nonaccrual status, TDRs which have been renegotiated to less than the original contractual rates (reduced-rate loans) and foreclosed property. TDRs include performing and nonperforming loans, with nonperforming TDRs on either nonaccrual or reduced-rate status. Certain provisions within the CARES Act encourage financial institutions to practice prudent efforts to work with borrowers impacted by COVID-19. Under these provisions, modifications

deemed to be COVID-19-related would not be considered a TDR if the loan was not more than 30 days past due as of December 31, 2019 and the deferral was executed between March 1, 2020 and the earlier of 60 days after the date of termination of the COVID-19 national emergency or December 31, 2020. The banking regulators issued similar guidance, which also clarified that a COVID-19-related modification should not be considered a TDR if the borrower was current on payments at the time the underlying loan modification program was implemented and if the modification was considered to be short-term. Modifications are first evaluated for eligibility under the CARES Act, then the interagency guidance if they do not qualify for the CARES Act relief. Modifications that are not eligible for either program continue to follow the Corporation’s established TDR policy. For loans not otherwise reportable as past due or nonaccrual, financial institutions are generally not expected to designate loans with deferrals granted due to COVID-19 as past due or nonaccrual. As of June 30, 2020, the Corporation granted payment deferrals for approximately 2,100 obligors with an aggregate loan balance of $4.5 billion, which primarily consisted of commercial loans, including $57 million of loans on their second deferral.

The following table presents a summary of nonperforming assets and past due loans.

Table of Contents

The following table presents a summary of total criticized loans. The Corporation's criticized list is consistent with the Special Mention, Substandard and Doubtful categories defined by regulatory authorities. Risk ratings are adjusted as appropriate based on dialogue with borrowers and review of current and projected financial performance, including liquidity and cash flow forecasts as well as receivable and inventory levels. Criticized loans with balances of $2 million or more on nonaccrual status or loans with balances of $1 million or more whose terms have been modified in a TDR are individually subjected to quarterly credit quality reviews, and the Corporation may establish specific allowances for such loans. A table of loans by credit quality indicator included in Note 4 to the consolidated financial statements provides further information about the balances comprising total criticized loans.

(dollar amounts in millions)			June 30, 2020						March 31, 2020						December 31, 2019
Total criticized loans			$	3,379					$	2,457					$	2,120
As a percentage of total loans			6.3		%				4.6		%				4.2		%

The $1.3 billion increase in criticized loans during the six months ended June 30, 2020 included increases of $564 million in general Middle Market and $475 million in Energy.

Concentrations of Credit Risk

Concentrations of credit risk may exist when a number of borrowers are engaged in similar activities, or activities in the same geographic region, and have similar economic characteristics that would cause them to be similarly impacted by changes in economic or other conditions. The Corporation has concentrations of credit risk with the automotive and commercial real estate industries. All other industry concentrations, as defined by management, individually represented less than 10 percent of total loans at June 30, 2020.

Automotive Lending - Dealer:

The following table presents a summary of dealer loans.

			June 30, 2020																		December 31, 2019
(in millions)			Loans Outstanding						Percent of Total Loans						Loans Outstanding						Percent of Total Loans

Other			3,077												3,447
Total dealer			$	5,048					9.4		%				$	7,414					14.7 %

Substantially all dealer loans are in the National Dealer Services business line and primarily include floor plan financing and other loans to automotive dealerships. Floor plan loans, included in commercial loans in the Consolidated Balance Sheets, totaled $2.0 billion at June 30, 2020, a decrease of $2.0 billion compared to $4.0 billion at December 31, 2019 due to lower automotive inventory precipitated by the interruption in automotive production. At June 30, 2020 and December 31, 2019, other loans to automotive dealers in the National Dealer Services business line totaled $3.1 billion and $3.4 billion, respectively, including $2.0 billion of owner-occupied commercial real estate mortgage loans at both June 30, 2020 and December 31, 2019, respectively.

Nonaccrual dealer loans totaled $1 million at June 30, 2020 and $9 million at December 31, 2019. Dealer loan net charge-offs totaled $1 million for the six months ended June 30, 2020, compared to none for the six months ended June 30, 2019.

Automotive Lending- Production:

The following table presents a summary of loans to borrowers involved with automotive production.

			June 30, 2020																		December 31, 2019
(in millions)			Loans Outstanding						Percent of Total Loans						Loans Outstanding						Percent of Total Loans

Domestic			$	1,040											$	963
Foreign			432												286
Total production			$	1,472					2.8		%				$	1,249					2.5 %

Loans to borrowers involved with automotive production, primarily Tier 1 and Tier 2 suppliers, totaled $1.5 billion and $1.2 billion at June 30, 2020 and December 31, 2019, respectively. These borrowers could face financial difficulties due to disruptions in auto production as well as their supply chains and logistics operations as a result of the COVID-19 pandemic. As such, management prudently continued to increase allocated reserves for this portfolio as of June 30, 2020.

Total commercial real estate			$	5,839					$	8,038					$	13,877					$	5,220					$	7,794					$	13,014

(a)Primarily loans to real estate developers.

(b)Primarily loans secured by owner-occupied real estate.

The Corporation limits risk inherent in its commercial real estate lending activities by monitoring borrowers directly involved in the commercial real estate markets and adhering to conservative policies on loan-to-value ratios for such loans. Commercial real estate loans, consisting of real estate construction and commercial mortgage loans, totaled $13.9 billion at June 30, 2020, an increase of $863 million compared to December 31, 2019, of which $5.8 billion, or 42 percent, were to borrowers in the Commercial Real Estate business line, including loans to real estate developers. The remaining $8.0 billion, or 58 percent, of commercial real estate loans in other business lines consisted primarily of owner-occupied commercial mortgages, which bear credit characteristics similar to non-commercial real estate business loans.

The real estate construction loan portfolio primarily contains loans made to long-tenured customers with satisfactory completion experience. Criticized real estate construction loans in the Commercial Real Estate business line totaled $17 million and $31 million at June 30, 2020 and December 31, 2019, respectively. In other business lines, there were $14 million criticized real estate construction loans at June 30, 2020, compared to none at December 31, 2019. There were no real estate construction loan charge-offs in either of the six-month periods ended June 30, 2020 and 2019.

Commercial mortgage loans are loans where the primary collateral is a lien on any real property and are primarily loans secured by owner-occupied real estate. Real property is generally considered primary collateral if the value of that collateral represents more than 50 percent of the commitment at loan approval. Loans in the commercial mortgage portfolio generally mature within three to five years. Criticized commercial mortgage loans in the Commercial Real Estate business line totaled $54 million and $55 million at June 30, 2020 and December 31, 2019, respectively. In other business lines, $422 million and $242 million of commercial mortgage loans were criticized at June 30, 2020 and December 31, 2019, respectively. Commercial mortgage loan net recoveries were $2 million for both the six months ended June 30, 2020 and 2019.

Residential Real Estate Lending

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, totaled $3.6 billion, or 7 percent of total loans, at June 30, 2020. The following table summarizes the Corporation's residential mortgage and home equity loan portfolios by geographic market.

			June 30, 2020																																										December 31, 2019

The residential real estate portfolio is principally located within the Corporation's primary geographic markets. Substantially all residential real estate loans past due 90 days or more are placed on nonaccrual status, and substantially all junior lien home equity loans that are current or less than 90 days past due are placed on nonaccrual status if full collection of the senior position is in doubt. At no later than 180 days past due, such loans are charged off to current appraised values less costs to sell.

Residential mortgages totaled $1.9 billion at June 30, 2020, and were primarily larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.9 billion of residential mortgage loans outstanding, $24 million were on nonaccrual status at June 30, 2020. The home equity portfolio totaled $1.7 billion at June 30, 2020, of which $1.6 billion was outstanding under primarily variable-rate, interest-only home equity lines of credit, $88 million were in amortizing status and $20 million were closed-end home equity loans. Of the $1.7 billion of home equity loans outstanding, $21 million were on nonaccrual status at June 30, 2020. A majority of the home equity portfolio was secured by junior liens at June 30, 2020. 

Energy Lending

The Corporation has a portfolio of Energy loans included in commercial loans in the Consolidated Balance Sheets. Customers in the Corporation's Energy line of business (approximately 140 relationships) are engaged in three segments of the oil and gas business: exploration and production (E&P), midstream and energy services. E&P generally includes such activities as searching for potential oil and gas fields, drilling exploratory wells and operating active wells. Commitments to E&P borrowers are generally subject to semi-annual borrowing base re-determinations based on a variety of factors including updated pricing (reflecting market and competitive conditions), energy reserve levels and the impact of hedging. The midstream sector is generally involved in the transportation, storage and marketing of crude and/or refined oil and gas products. The Corporation's energy services customers provide products and services primarily to the E&P segment.

The following table summarizes information about loans in the Corporation's Energy business line.

			June 30, 2020																								December 31, 2019
(dollar amounts in millions)			Outstandings									Nonaccrual			Criticized (a)						Outstandings									Nonaccrual			Criticized (a)

As a percentage of total Energy loans															5		%	40		%										2		%	16		%

(a) Includes nonaccrual loans.

Loans in the Energy business line totaled $2.1 billion, or 4 percent of total loans at June 30, 2020, and $2.2 billion at December 31, 2019, a decrease of $135 million. Total exposure, including unused commitments to extend credit and letters of credit, was $3.4 billion and $4.3 billion at June 30, 2020 and December 31, 2019, respectively.

The decrease in total exposure in the Energy business line primarily reflected reduced borrowing bases as a result of lower oil and gas prices. At June 30, 2020, the Corporation had completed approximately 90 percent of the Spring borrowing base re-determinations, resulting in an average reduction to the borrowing bases of 20 percent. Utilization increased to 60 percent primarily as a result of the reduction in exposure at June 30, 2020. The value and coverage benefit of hedging contracts are dependent upon the oil/gas price in each contract, as well as the operational costs, which are different for each borrower. As of June 30, 2020, 73 percent of the Corporation's E&P customers had at least 50 percent of their oil and/or gas production hedged up to one year and 37 percent of customers had at least 50 percent of production hedged for two years or more.

The Corporation's allowance methodology considers the various risk elements within the loan portfolio. When merited, the Corporation may incorporate a qualitative reserve component for Energy loans. The allocation of reserves for Energy loans remained over 10 percent of the Energy portfolio at June 30, 2020 in response to oil market supply/demand imbalances as well as reduced capital market activity. The supply/demand imbalance has been exacerbated by the economic impacts from the COVID-19 pandemic, further stressing the Energy portfolio. Net credit-related Energy charge-offs were $45 million and $112 million for the three- and six-month periods ended June 30, 2020, respectively, compared to $25 million and $33 million for the same periods in 2019. Nonaccrual Energy loans increased $59 million to $102 million at June 30, 2020, compared to December 31, 2019. Criticized Energy loans increased $475 million to $841 million, or 25 percent of total criticized loans, at June 30, 2020.

Leveraged Loans

Certain loans in the Corporation's commercial portfolio are considered leveraged transactions. These loans are typically used for mergers, acquisitions, business recapitalizations, refinancing and equity buyouts. To help mitigate the risk associated with these loans, the Corporation focuses on middle market companies with highly capable management teams, strong sponsors and solid track records of financial performance. Industries prone to cyclical downturns and acquisitions with a high degree of integration risk are generally avoided. Other considerations include the sufficiency of collateral, the level of balance sheet leverage and the adequacy of financial covenants. During the underwriting process, cash flows are stress-tested to evaluate the borrowers' abilities to handle economic downturns and an increase in interest rates. Management considers the leveraged loan portfolio to be one of the most sensitive to economic impacts stemming from the COVID-19 pandemic and

social distancing policies and has continued to set aside increased reserves for this portfolio as of June 30, 2020. Certain energy, automotive production and loans in other portfolios specifically identified as subject to additional stress due to COVID-19 impacts are also considered leveraged transactions.

The FDIC defines higher-risk commercial and industrial (HR C&I) loans for assessment purposes as loans generally with leverage of four times total debt to earnings before interest, taxes and depreciation (EBITDA) as well as three times senior debt to EBITDA, excluding certain collateralized loans.

The following table summarizes information about HR C&I loans.

Other Sectors Most at Risk due to Economic Stress Resulting from COVID-19 Impacts

        The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains and increased unemployment levels. The resulting temporary closure of many businesses and the implementation of social distancing and sheltering in place policies may impact many of the Corporation’s customers. In addition to the energy, automotive production and leveraged loan portfolios, the Corporation considers the following sectors of its loan portfolio to be most vulnerable to financial risks from business disruptions caused by the pandemic spread mitigation efforts. For further discussion, see Item 1.A "Risk Factors" on page 65 of this report.

Market and Liquidity Risk

Market risk represents the risk of loss due to adverse movement in prices, including interest rates, foreign exchange rates, commodity prices and equity prices. Liquidity risk represents the risk that the Corporation does not have sufficient access to funds to maintain its normal operations at all times, or does not have the ability to raise or borrow funds at a reasonable cost at all times.

The Asset and Liability Policy Committee (ALCO) of the Corporation establishes and monitors compliance with the policies and risk limits pertaining to market and liquidity risk management activities. ALCO meets regularly to discuss and review market and liquidity risk management strategies and consists of executive and senior management from various areas of the Corporation, including treasury, finance, economics, lending, deposit gathering and risk management. Corporate Treasury mitigates market and liquidity risk under the direction of ALCO through the actions it takes to manage the Corporation's market, liquidity and capital positions.

In addition to assessing liquidity risk on a consolidated basis, Corporate Treasury also monitors the parent company's liquidity and has established limits for the minimum number of months into the future in which the parent company can meet existing and forecasted obligations without the support of additional dividends from subsidiaries. ALCO's liquidity policy requires the parent company to maintain sufficient liquidity to meet expected capital and debt obligations with a target of 24 months but no less than 18 months.

Corporate Treasury and the Enterprise Risk Division support ALCO in measuring, monitoring and managing interest rate risk as well as all other market risks. Key activities encompass: (i) providing information and analyses of the Corporation's

balance sheet structure and measurement of interest rate and all other market risks; (ii) monitoring and reporting of the Corporation's positions relative to established policy limits and guidelines; (iii) developing and presenting analyses and strategies to adjust risk positions; (iv) reviewing and presenting policies and authorizations for approval; and (v) monitoring of industry trends and analytical tools to be used in the management of interest rate and all other market and liquidity risks.

Interest Rate Risk

Net interest income is the primary source of revenue for the Corporation. Interest rate risk arises in the normal course of business due to differences in the repricing and cash flow characteristics of assets and liabilities, primarily through the Corporation's core business activities of extending loans and acquiring deposits. The Corporation's balance sheet is predominantly characterized by floating-rate loans funded by core deposits. Including the impact of interest rate swaps converting floating-rate loans to fixed, the Corporation's loan composition at June 30, 2020 was 53 percent 30-day LIBOR, 8 percent other LIBOR (primarily 60-and 90-day), 13 percent prime and 26 percent fixed rate. This creates sensitivity to interest rate movements due to the imbalance between the faster repricing of the floating-rate loan portfolio versus deposit products. In addition, the growth and/or contraction in the Corporation's loans and deposits may lead to changes in sensitivity to interest rate movements in the absence of mitigating actions. Examples of such actions are purchasing fixed-rate investment securities, which provide liquidity to the balance sheet and act to mitigate the inherent interest sensitivity, as well as hedging with interest rate swaps and options. Other mitigating factors include interest rate floors on a portion of the loan portfolio. The Corporation actively manages its exposure to interest rate risk with the principal objective of optimizing net interest income and the economic value of equity while operating within acceptable limits established for interest rate risk and maintaining adequate levels of funding and liquidity.

Since no single measurement system satisfies all management objectives, a combination of techniques is used to manage interest rate risk. These techniques examine the impact of interest rate risk on net interest income and the economic value of equity under a variety of alternative scenarios, including changes in the level, slope and shape of the yield curve utilizing multiple simulation analyses. Simulation analyses produce only estimates of net interest income as the assumptions used are inherently uncertain. Actual results may differ from simulated results due to many factors, including, but not limited to, the timing, magnitude and frequency of changes in interest rates, market conditions, regulatory impacts and management strategies.

Sensitivity of Net Interest Income to Changes in Interest Rates

The analysis of the impact of changes in interest rates on net interest income under various interest rate scenarios is management's principal risk management technique. Management models a base-case net interest income under an unchanged interest rate environment. Existing derivative instruments entered into for risk management purposes as of the balance sheet dates are included in the analysis, but no additional hedging is forecasted. At June 30, 2020, these derivative instruments comprise interest rate swaps that convert $2.7 billion of fixed-rate medium- and long-term debt to variable rates through fair value hedges and convert $5.6 billion of variable-rate loans to fixed rates through cash flow hedges. This base-case net interest income is then compared against interest rate scenarios in which rates rise or decline 100 basis points (with a floor of zero percent) in a linear, non-parallel fashion from the base case over 12 months, resulting in an average increase or decrease in short-term interest rates of 50 basis points over the period.

Each scenario includes assumptions such as loan growth, investment security prepayment levels, depositor behavior, yield curve changes, loan and deposit pricing, and overall balance sheet mix and growth. In this low rate environment, depositors have maintained a higher level of liquidity and their historical behavior may be less indicative of future trends. As a result, the rising rate scenario reflects a greater decrease in deposits than experienced historically as rates rise. Changes in actual economic activity may result in a materially different interest rate environment as well as a balance sheet structure that is different from the changes management included in its simulation analysis.

The table below, as of June 30, 2020 and December 31, 2019, displays the estimated impact on net interest income during the next 12 months by relating the base case scenario results to those from the rising and declining rate scenarios described above.

			June 30, 2020																		December 31, 2019
(dollar amounts in millions)			Amount						%						Amount						%
Change in Interest Rates:												Change in Interest Rates:
Rising 100 basis points			$	130					7		%	Rising 100 basis points			$	90					4		%
Declining to zero percent			(32)						(2)			Declining 100 basis points			(135)						(6)

The change in sensitivity to interest rates from December 31, 2019 to June 30, 2020 was driven by growth in fixed-rate loans, as well as the addition of swaps converting variable-rate loans to fixed rates, partially offset by growth in core deposits. Also, decreased sensitivity to declining interest rates was related to limited downward movement in interest rates before hitting zero percent.

Sensitivity of Economic Value of Equity to Changes in Interest Rates

In addition to the simulation analysis on net interest income, an economic value of equity analysis provides an alternative view of the interest rate risk position. The economic value of equity is the difference between the estimate of the economic value of the Corporation's financial assets, liabilities and off-balance sheet instruments, derived through discounting cash flows based on actual rates at the end of the period, and the estimated economic value after applying the estimated impact of rate movements. The Corporation primarily monitors the percentage change on the base-case economic value of equity. The economic value of equity analysis is based on an immediate parallel 100 basis point shock.

The table below, as of June 30, 2020 and December 31, 2019, displays the estimated impact on the economic value of equity from the interest rate scenario described above.

			June 30, 2020																		December 31, 2019
(dollar amounts in millions)			Amount						%						Amount						%
Change in Interest Rates:												Change in Interest Rates:
Rising 100 basis points			$	1,319					15		%	Rising 100 basis points			$	716					7		%
Declining to zero percent			(479)						(54)			Declining 100 basis points			(1,178)						(12)

The sensitivity of the economic value of equity to rising rates increased from December 31, 2019 to June 30, 2020 due to changes in deposit pay rates and expected lives. The sensitivity to declining rates decreased due to changes in balance sheet composition as well as limited remaining downward movement in rates before hitting modeled zero-percent floors.

LIBOR Transition

On July 27, 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, publicly announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. The Corporation has substantial exposure to LIBOR-based products, including loans, securities, derivatives and hedges, and is preparing for a transition from LIBOR toward alternative rates. A dedicated program office and governance structure has been established, with direction and oversight from the Chief Executive Officer, Chief Financial Officer and Chief Risk Officer. A cross-functional implementation team has been tasked with execution of an enterprise LIBOR transition plan road map. Comerica’s enterprise transition milestones align with recommendations from the Alternative Reference Rates Committee (ARRC) for both best practices and recommended 2020 objectives. As of the second quarter of 2020, customer disclosure information for both consumer and commercial loans are being provided for new originations. Execution plans are in place to begin incorporating fallback language related to legacy LIBOR commercial loans by the end of 2020. Additional milestones for products originated on alternative reference rates will be executed in alignment with market and industry decisions. The Corporation continues to monitor market developments and regulatory updates, as well as collaborate with regulators and industry groups on the transition. For a discussion of the various risks facing the Corporation in relation to the transition away from LIBOR, refer to "Item 1A. Risk Factors" beginning on page 12 of the Corporation's 2019 Annual Report.

Wholesale Funding

The Corporation may access the purchased funds market when necessary, which includes a variety of funding sources. Capacity for incremental purchased funds at June 30, 2020 included short-term Federal Home Loan Bank (FHLB) advances, the ability to purchase federal funds, sell securities under agreements to repurchase as well as issue deposits through brokers. Purchased funds increased to $839 million at June 30, 2020 compared to $295 million at December 31, 2019, driven by increases in short-term FHLB advances. At June 30, 2020, the Bank had pledged loans totaling $21.2 billion which provided for up to $16.2 billion of available collateralized borrowing with the Federal Reserve Bank (FRB).

The Bank is a member of the FHLB of Dallas, Texas, which provides short- and long-term funding to its members through advances collateralized by real estate-related assets. Actual borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At June 30, 2020, $18.3 billion of real estate-related loans and $5.2 billion of investment securities were pledged to the FHLB as collateral for current and potential future borrowings. The Corporation had $3.6 billion of FHLB long-term advances, maturing between 2026 and 2028, as well as $750 million in short-term advances outstanding at June 30, 2020, and capacity for potential future borrowings of approximately $10.1 billion. The Corporation expects to repay $1.0 billion of its outstanding FHLB long-term advances in third quarter 2020.

Additionally, the Bank had the ability to issue up to $13.5 billion of debt at June 30, 2020 under an existing $15.0 billion note program which allows the issuance of debt with maturities between three months and 30 years. The Corporation also maintains a shelf registration statement with the Securities and Exchange Commission from which it may issue debt and/or equity securities.

The ability of the Corporation and the Bank to raise funds at competitive rates may be impacted by rating agencies' views of the credit quality, liquidity, capital and earnings of the Corporation and the Bank. As of June 30, 2020, the three major rating agencies had assigned the ratings below to long-term senior unsecured obligations of the Corporation and the Bank. A security rating is not a recommendation to buy, sell, or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating.

The Corporation satisfies liquidity needs with either liquid assets or various funding sources. Liquid assets totaled $20.5 billion and $17.9 billion at June 30, 2020 and December 31, 2019, respectively. Liquid assets include cash and due from banks, federal funds sold, interest-bearing deposits with banks, other short-term investments and unencumbered investment securities.

The Corporation performs monthly liquidity stress testing to evaluate its ability to meet funding needs in hypothetical stressed environments. Such environments cover a series of broad events, distinguished in terms of duration and severity. The evaluation as of June 30, 2020 projected sufficient sources of liquidity were available under each series of events.

Total liquidity sources, comprised of liquid assets and remaining borrowing capacity with the FRB and the FHLB, totaled $46.8 billion at June 30, 2020.

CRITICAL ACCOUNTING POLICIES

The Corporation’s consolidated financial statements are prepared based on the application of accounting policies, the most significant of which are described in Note 1 to the consolidated financial statements included in the Corporation's 2019 Annual Report. These policies require numerous estimates and strategic or economic assumptions, which may prove inaccurate or subject to variations. Changes in underlying factors, assumptions or estimates could have a material impact on the Corporation’s future financial condition and results of operations. At December 31, 2019, the most critical of these significant accounting policies were the policies related to the allowance for credit losses, fair value measurement, goodwill, pension plan accounting and income taxes. These policies were reviewed with the Audit Committee of the Corporation’s Board of Directors and are discussed more fully on pages F-34 through F-36 in the Corporation's 2019 Annual Report. Below are significant changes to the Corporation's critical accounting policies or estimates since the Corporation's 2019 Annual Report.

ALLOWANCE FOR CREDIT LOSSES

The Corporation adopted new accounting guidance for estimating credit losses, known as the CECL framework, in first quarter 2020. In accordance with CECL, the allowance for credit losses, which includes both the allowance for loan losses and the allowance for credit losses on lending-related commitments, is calculated with the objective of maintaining a reserve for current expected credit losses over the remaining contractual life of the portfolio.

In determining the allowance for credit losses for the majority of its lending portfolio, the Corporation uses reserve factors, based on estimated probability of default for internal risk ratings and loss given default. Management applies reserve factors to pools of loans and lending-related commitments with similar risk characteristics, calibrates these factors using economic forecasts and incorporates qualitative adjustments. For further discussion of the methodology used in the determination of the allowance for credit losses, refer to Note 1 to the consolidated financial statements. For further discussion on the economic forecast incorporated into the second quarter 2020 model, refer to the “Risk Management” section of this report.

Management's determination of the appropriateness of the allowance is based on periodic evaluations of the loan portfolio, lending-related commitments, current as well as forecasted economic factors and other relevant factors. The calculation is inherently subjective and requires management to exercise significant judgment in developing assumptions into the estimate, the most significant of which are the loan risk rating process, development of economic forecasts and application of qualitative adjustments. Sensitivities are disclosed to demonstrate how changes in loan risk ratings and economic forecast scenarios may impact the allowance for credit losses. Sensitivities only consider changes to each specific assumption in isolation and their impact to the quantitative modeled results; however, they do not contemplate impacts to the qualitative framework.

Loan Risk Rating Process

Loss factors are applied to pools of loans based on the Corporation's internal risk rating system; therefore, loss estimates are highly dependent on the accuracy of the risk rating assigned to each loan. The inherent imprecision in the risk rating system resulting from inaccuracy in assigning and/or entering risk ratings in the loan accounting system is monitored by the Corporation's asset quality review function. Changes to internal risk ratings, beyond the forecasted migration inherent in the credit models, would result in a different estimated allowance for credit losses. To illustrate, if five percent of the individual risk ratings were adjusted down by one rating across all pools, the allowance for loan losses as of June 30, 2020 would change by approximately $13 million.

Forecasted Economic Variables

Historical loss factor estimates are calibrated to economic forecasts over the reasonable and supportable forecast period based on the projected performance of specific economic variables that statistically correlate with the probability of default and loss given default pools. Loss estimates revert to historical loss experience for contractual lives beyond the forecast period. Management selects economic variables it believes to be most relevant based on the composition of the loan portfolio and customer base, including forecasted levels of employment, gross domestic product, corporate bond and treasury spreads, industrial production levels, consumer and commercial real estate price indices as well as housing statistics.

The allowance for credit losses is highly sensitive to the economic forecasts used to develop the estimate. Due to the high level of uncertainty regarding significant assumptions, such as the ultimate impact of the global pandemic and effectiveness of the government stimulus, the Corporation evaluated a range of economic scenarios, including a more severe economic forecast scenario, with varying speeds of recovery. The following table summarizes the more severe forecast scenario for the economic variables that are most impactful.

Table of Contents

Economic Variable			More Severe Forecast
Real GDP growth			Grows by 13 percent in third quarter 2020 followed by a short-term contraction, then reaches a growth rate of 7 percent as the forecast period ends part-way through an economic recovery.
Unemployment rate			Remains at elevated levels between 10 percent and 12 percent throughout the forecast period.
Corporate BBB bond to 10-year Treasury bond spreads			Remains between 3.75 percent and 4.15 percent in the near-term before normalizing into spreads below 2 percent by the end of the forecast period.
Oil Prices			Price remains low throughout the forecast period, improving to above $25 per barrel by the second quarter 2022.

Selecting a different forecast in the current environment could result in significantly different estimated allowance for credit losses. To illustrate, absent model overlays and other qualitative adjustments that are part of the quarterly reserving process, if the Corporation selected the more severe scenario to inform its models, the allowance for credit losses as of June 30, 2020 would increase by approximately $1.6 billion. However, factoring in model overlays and qualitative adjustments could result in a materially different estimate under a more severe scenario.

Qualitative Adjustments

The Corporation includes qualitative adjustments, as appropriate, intended to capture the impact of uncertainties not reflected in the quantitative estimate, including foresight risk, model imprecisions and input imprecisions. Qualitative adjustments for foresight risk, reflect the inherent imprecision in economic forecasts and may be included based on management’s evaluation of different forecast scenarios, ranging from more benign to more severe, and known recent events impacting the Corporation’s portfolio. Model imprecision adjustments and model overlays may be included to mitigate known limitations in the quantitative models. Input imprecision includes adjustments for portfolios where recent historical losses exceed expected losses or known recent events are expected to alter risk ratings once evidence is acquired, as well as a qualitative assessment of the lending environment, including underwriting standards, current economic and political conditions, and other factors affecting credit quality. Qualitative reserves at June 30, 2020 primarily included adjustments for uncertainties related to forecasted economic variables and model imprecision.

Other Considerations

To the extent actual outcomes differ from management estimates, additional provision for credit losses may be required that would adversely impact earnings in future periods. The allowance is assigned to business segments and any earnings impact resulting from actual outcomes differing from management estimates would primarily affect the Commercial Bank segment.

GOODWILL

Goodwill is initially recorded as the excess of the purchase price over the fair value of net assets acquired in a business combination and is subsequently evaluated at least annually for impairment. Goodwill impairment testing is performed at the reporting unit level, equivalent to a business segment or one level below. The Corporation has three reporting units: the Commercial Bank, the Retail Bank and Wealth Management. At June 30, 2020, goodwill totaled $635 million, including $473 million allocated to the Commercial Bank, $101 million allocated to the Retail Bank and $61 million allocated to Wealth Management.

The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and may elect to perform a quantitative impairment analysis or first conduct a qualitative analysis to determine if a quantitative analysis is necessary. Additionally, the Corporation evaluates goodwill impairment on an interim basis if events or changes in circumstances between annual tests indicate additional testing may be warranted to determine if goodwill might be impaired.

In the first quarter of 2020, economic conditions deteriorated significantly with the spread of the coronavirus global pandemic. The outbreak resulted in social distancing requirements throughout the world, severely restricting the economy. In response to the crisis, the Federal Reserve lowered the Federal Funds rate in March 2020 to close to zero. Additionally, the U.S. government initiated numerous measures to support the economy, including the CARES Act. Given the economic deterioration in the first quarter of 2020, the Corporation assessed whether the events and circumstances resulted in it being more likely than not that the fair value of any reporting unit was less than its carrying value. Impairment indicators considered comprised economic conditions, including projections of the duration of current conditions and timing of a potential recovery; industry and market considerations; government intervention and regulatory updates; the impact of recent events to financial performance and cost factors of the reporting units; performance of the Corporation’s stock and other relevant events. The Corporation further considered the amount by which fair value exceeded book value for each unit in the most recent quantitative analysis

and sensitivities performed. At the conclusion of the first quarter 2020 assessment, the Corporation determined that it was more likely than not that the fair value of each reporting unit exceeded its carrying value.

In second quarter 2020, the Corporation performed a quantitative goodwill impairment test in response to continued macroeconomic deterioration and the ongoing impacts to the banking industry and markets in which the Corporation operates. The estimated fair values of the reporting units were determined using a blend of two commonly used valuation techniques: the market approach and the income approach. For the market approach, valuations of reporting units considered a combination of earnings and equity multiples from companies with characteristics similar to the reporting unit. Since the fair values determined under the market approach are representative of noncontrolling interests, the valuations incorporated a control premium. For the income approach, estimated future cash flows were derived from internal forecasts and economic expectations for each reporting unit. In the short- and mid-term, forecasts incorporated current economic conditions and ongoing impacts of the global pandemic, including a federal funds target near zero and an elevated allowance for credit losses. Long-term projections reflected normalized rate and credit environments, as well as a long-term rate of return for each reporting unit. Projections were discounted using an applicable discount rate to calculate fair value. The discount rate was based on the imputed cost of equity capital appropriate for each reporting unit, which incorporates the risk-free rate of return, the level of non-diversified risk associated with companies with characteristics similar to the reporting unit, a size risk premium and a market equity risk premium. The discount rate further reflected the uncertainty of current economic conditions and potential impacts to the forecasted financial information. The combined fair value of all units was compared to the Corporation’s market capitalization for reasonableness. At the conclusion of the quantitative impairment test in second quarter 2020, the estimated fair values of all reporting units substantially exceeded their carrying amounts, including goodwill.

The test included evaluation of various factors that continue to rapidly evolve and for which significant uncertainty remains, including the impact of the coronavirus global pandemic to the economy and ongoing government intervention to mitigate that impact. Further weakening in the economic environment, such as continued decline in the performance of the reporting units or other factors, could cause the fair value of one or more of the reporting units to fall below their carrying value, resulting in a goodwill impairment charge. Additionally, new legislative or regulatory changes not anticipated in management's expectations may cause the fair value of one or more of the reporting units to fall below the carrying value, resulting in a goodwill impairment charge. Any impairment charge would not affect the Corporation's regulatory capital ratios, tangible common equity ratio or liquidity position.

SUPPLEMENTAL FINANCIAL DATA

The Corporation believes non-GAAP measures are meaningful because they reflect adjustments commonly made by management, investors, regulators and analysts to evaluate the adequacy of common equity and our performance trends. Tangible common equity is used by the Corporation to measure the quality of capital and the return relative to balance sheet risk.

Common equity tier 1 capital ratio removes preferred stock from the Tier 1 capital ratio as defined by and calculated in conformity with bank regulations. The tangible common equity ratio removes the effect of intangible assets from capital and total assets. Tangible common equity per share of common stock removes the effect of intangible assets from common shareholders' equity per share of common stock.

The following table provides a reconciliation of non-GAAP financial measures and regulatory ratios used in this financial review with financial measures defined by GAAP.

ITEM 1. Legal Proceedings

For information regarding the Corporation's legal proceedings, see "Part I. Item 1. Note 12 – Contingent Liabilities," which is incorporated herein by reference.

ITEM 1A. Risk Factors

        Other than as set forth below, there have been no material changes in the Corporation’s risk factors as previously disclosed in our Form 10-K for the fiscal year ended December 31, 2019 in response to Part I, Item 1A. of such Form 10-K. Such risk factors are incorporated herein by reference.  

        The following risk factor is added under "General Risk":

•The COVID-19 pandemic has impacted our business, and the ultimate impact on our business and financial results will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic.

The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels. In addition, the pandemic has resulted in temporary closures of many businesses and the institution of social distancing and sheltering in place requirements in many states and communities. As a result, the demand for our products and services may be significantly impacted. Furthermore, the pandemic has influenced and could further influence the recognition of credit losses in our loan portfolios and has increased and could further increase our allowance for credit losses, particularly as businesses remain closed and as more customers may draw on their lines of credit or seek additional loans to help finance their businesses. Similarly, because of changing economic and market conditions affecting issuers, the securities we hold may lose value. Our business operations may also be disrupted if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the pandemic, and we have already temporarily closed certain of our branches and offices. In response to the pandemic, we have also enacted hardship relief assistance for customers experiencing financial difficulty as a result of COVID-19, including fee and penalty waivers, loan deferrals or other scenarios that may help our customers. As well, we are a lender for the Small Business Administration's Paycheck Protection Program ("PPP") and other SBA, Federal Reserve or United States Treasury programs that have been or may be created in the future in response to the pandemic. These programs are new and

their effects on Comerica's business are uncertain. The extent to which the COVID-19 pandemic impacts our business, results of operations, and financial condition, as well as our regulatory capital and liquidity ratios, will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic.

        Below we amend the following risk factor discussed under "Credit Risk" in Part II, "Item 1A. Risk Factors" in Part I, Item 1A. of our Form 10-K for the fiscal year ended December 31, 2019.

•Declines in the businesses or industries of Comerica's customers - in particular, the energy industry - could cause increased credit losses or decreased loan balances, which could adversely affect Comerica.

Comerica's business customer base consists, in part, of customers in volatile businesses and industries such as the automotive, commercial real estate, residential real estate and energy industries. These industries are sensitive to global economic conditions, supply chain factors and/or commodities prices. Any decline in one of these businesses or industries could cause increased credit losses, which in turn could adversely affect Comerica. Further, any decline in these businesses or industries could cause decreased borrowings, either due to reduced demand or reductions in the borrowing base available for each customer loan.

In particular, oil and gas prices have fallen since the beginning of 2020 due to global events. Loans in the Energy business line were $2.1 billion, or approximately 4 percent of total loans, at June 30, 2020. At June 30, 2020, the reserve allocation for Energy loans was over 10 percent of total Energy loans. If oil and gas prices continue to remain depressed for a prolonged period of time, Comerica's energy portfolio could experience increased credit losses, which could adversely affect Comerica's financial results. Furthermore, a prolonged period of low oil prices could also have a negative impact on the Texas economy, which could have a material adverse effect on Comerica’s business, financial condition and results of operations. For more information regarding Comerica's energy portfolio, please see “Energy Lending” beginning on page 56 of this report.

For more information regarding certain of Comerica's lines of business, please see "Concentration of Credit Risk," "Automotive Lending," "Commercial Real Estate Lending," "Residential Real Estate Lending" and “Energy Lending” on pages F-25 through F-27 of Comerica’s Form 10-K for the fiscal year ended December 31, 2019.
