Notes to Consolidated Financial Statements (unaudited)
Comerica Incorporated and Subsidiaries

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 sixthree months ended June 30, 2019March 31, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.2020. 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, 2018.2019.
LeasesAllowance 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, 2019,2020, the Corporation adopted the provisions of Accounting Standards Update (ASU) No. 2016-02, “Leases (Topic 842),” (ASU 2016-02), for all open leases with a term greater than one year as of the adoption date, using the modified retrospective approach. Prior comparable periods are presented in accordance with previous guidance under Accounting Standards Codification (ASC) 840, “Leases.”
Topic 842 requires the recognition of a lease liability, measured as the present value of unpaid lease payments for operating leases where the Corporation is the lessee, and a corresponding right-of-use (ROU) asset for the right to use the leased properties. The Corporation elected not to reassess whether contracts are or contain leases, lease classification or initial direct costs for existing leases, a set of practical expedients for transition provided by ASU 2016-12. Further, the Corporation elected the practical expedient to use hindsight in determining the lease term and assessing impairment. The election of the hindsight practical expedient resulted in longer lease terms for a limited number of strategic locations based on relevant factors as of the adoption date.
The impact at adoption was increases of $329 million and $343 million to total assets and liabilities, respectively, and a $14 million reduction to retained earnings. The increase in total assets was due to the recognition of ROU assets recorded in accrued income and other assets, and the increase in total liabilities was due to corresponding recognition of lease payment liabilities recorded in accrued expenses and other liabilities.
Operating lease liabilities reflect the Corporation’s obligation to make future lease payments, primarily for real estate locations. Lease terms typically comprise contractual terms but may include extension options reasonably certain of being exercised at lease inception for certain strategic locations such as regional headquarters. Payments are discounted using the rate the Corporation would pay to borrow amounts equal to the lease payments over the lease term (the Corporation’s incremental borrowing rate). The Corporation does not separate lease and non-lease components for contracts in which it is the lessee. ROU assets are measured based on lease liabilities adjusted for incentives as well as accrued and prepaid rent. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are recognized as incurred. Common area maintenance and other executory costs are the main components of variable lease payments. Operating and variable lease expenses are recorded in net occupancy expense in the Consolidated Statements of Income.
The Corporation is the lessor in sales-type, direct finance and leveraged lease arrangements. Leases are recorded at the principal balance outstanding, net of unearned income and charge-offs. Interest income is recognized using the interest method. The impact of adopting Topic 842 for lessor accounting was not significant.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," (ASU 2016-13), which addresses concerns regardingcommonly referred to as the perceived delay in recognition ofcurrent expected credit losses under the existing incurred loss model. The amendment introduces a new, single(CECL) model, for recognizing credit losses on all financial instruments presented on a cost basis. assets, except those accounted for at fair value through net income, using the modified retrospective approach.
Under the new model, entities must estimateTopic 326, current expected credit losses byare 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 update also requires additional qualitativeprevious 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 quantitative disclosurea $4 million reduction to allow users to better understanddeferred tax assets. A similar adjustment at December 31, 2019 would have caused a 2-basis-point increase in the credit risk withinCommon 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 the methodologies for determininglending arrangements with generally short contractual maturities. As a result, the allowance for credit losses.losses for business loans decreased $42 million. The allowance for credit losses increased $25 million for retail loans, given their longer contractual maturities.
ASU 2016-13Topic 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 were recorded on its AFS securities portfolio at transition.
Allowance for Loan Losses
The allowance for loan losses is effective forestimated on a quarterly basis and represents management’s estimates of current expected credit losses in the Corporation on January 1, 2020 and must be applied usingCorporation’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 modified retrospective approach with limited exceptions. The Corporation’s cross-functional implementation team, led by the Chief Financial Officer and Chief Credit Officer, continue to make progress in accordance with the detailed implementation plan for adoption. In prior periods, the Corporation developed and completed internal validations of new credit estimation models. The Corporation has implemented new processes and controls for the executionremaining contractual life of the new modelcollectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools. Business loans are assigned to pools based primarily on business line and is in the processCorporation’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 testing them. The implementationdefault 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.

team continuesThe calculation of current expected credit losses is inherently subjective, as it requires management to challenge current model assumptions and outputs, refineexercise judgment in determining appropriate factors used to determine the qualitative framework and finalize policies and disclosures. Additionally, limited parallel runs, which beganallowance. Some of the most significant factors in the fourth quarter 2018, will be enhanced throughout 2019 as more end-to-end processes, controlsquantitative allowance estimate are assigning internal risk ratings to loans, selecting the economic forecasts used to calibrate the reserve factors and policies are finalized.
Incorporatingdetermining the reasonable and supportable forecasts of economic conditions into the estimate of expected credit losses will require significant judgment, such as selecting economic variables and forecast scenarios as well as determining the appropriate length of the forecast horizon. Management will select economic variables it believes to be most relevant based on the composition of the loan portfolio and customer base, likely to include 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 forecasts ranging from more benign to more severe willperiod.
Internal Risk Ratings: Standard 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 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 loan portfolio. The Corporation anticipates using a two-year forecast horizon, which encompasses mostUnanticipated 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 remaining contractual lifeallowance. Such events, or others of its portfolio of commercial loans.
The ultimate impact of ASU 2016-13 will depend onsimilar nature, may result in the composition of the portfolio as well as economic conditions and forecasts at the time of adoption. Based on current factors, the overall allowanceneed for additional provision for credit losses is not expectedin order to materially change duemaintain 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 portfolio’s relatively short average contractual life. The commercial portfolio, comprising the majorityallowance.
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. 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 standard 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 expectedincluded 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 increasethe 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 Business Bank, the Retail Bank and Wealth Management.
The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and on an interim basis if events or changes in circumstances between annual tests suggest additional testing may be warranted to determine if goodwill might be impaired. The Corporation may choose to perform a qualitative assessment to determine whether it is more likely than not that the fair value of any reporting unit is less than its carrying amount, including goodwill. 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 consumer portfolio given its longer contractual maturities.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 2016-13 will beNo. 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 months ended March 31, 2020, software expense included $7 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 months ended March 31, 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 86 percent of the Corporation’s loans at March 31, 2020 were tied to LIBOR. The Corporation uses interest rate swaps to convert variable-LIBOR rate loans to fixed rates for approximately 10 percent of the loan portfolio. Additional contracts with exposure to LIBOR include swaps converted 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.
Equity securities, investmentInvestment securities available-for-sale, derivatives, and deferred compensation plan assetsplans and liabilitiesequity 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 impairednonaccrual loans and loans classified as troubled debt restructurings (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, 20182019 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.

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)Includes all loans not included in the categories of special mention, substandard or nonaccrual.
(b)Special mention loans are accruing loans that 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. This category is generally consistent with the "special mention" category as defined by regulatory authorities.
(c)Substandard loans are accruing loans that 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 also are distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. This category is generally consistent with the "substandard" category as defined by regulatory authorities.
(d)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 pages F-52 and F-53page F-51 in the Corporation's 20182019 Annual Report. A significant majority of nonaccrual loans are generally consistent with the "substandard" category and the remainder are generally consistent with the "doubtful" category as defined by regulatory authorities.
(e)Primarily loans to real estate developers.
(f)Primarily loans secured by owner-occupied real estate.
Loan interest receivable totaled $161 million and $172 million at March 31, 2020 and December 31, 2019, respectively, and was included in accrued income and other assets on the Consolidated Balance Sheets.
Substantially all individually evaluated loans are collateral-dependent and, at March 31, 2020, consisted primarily of commercial and commercial mortgage loans. Collateral-dependent commercial loans were secured by oil and gas assets, accounts receivable, inventory and equipment, and collateral-dependent commercial mortgage loans were secured by commercial real estate assets. The most significant change in collateral values during the first quarter of 2020 was a decrease in the value of oil and gas assets related to supply/demand imbalances in the energy market.

(b)Primarily loans secured by owner-occupied real estate.
(c)Includes bankruptcy loans for which the court has discharged the borrower's obligation and the borrower has not reaffirmed the debt.
The Corporation charges interest on principal balances outstanding during deferral periods. Additionally, none of the modifications involved forgiveness of principal. As a result, the current and future financial effects of the recorded balance of loans considered to be TDRs that were restructured during the six months ended June 30, 2019 and 2018 were insignificant.
At June 30, 2019both March 31, 2020 and December 31, 2018,2019, commitments to lend additional funds to borrowers whose terms have been modified in TDRs totaled $6 million and $20 million, respectively.$3 million. 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.

There were no loans restructured into two notes (AB note restructures) during either of the twelve-month periods ended June 30, 2019 and 2018.
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, and AB note restructures, a subsequent payment default is defined in terms of delinquency, when a principal or interest payment is 90 days past due. There were no subsequentSubsequent defaults of principal deferrals totaled $10 million in the three-month period ended March 31, 2020, compared to none in the comparable period in 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.


19

Table of Contents
Notes to Consolidated Financial Statements (unaudited)
Comerica Incorporated and Subsidiaries

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, 2019,March 31, 2020, counterparties with bilateral collateral agreements pledged $1 million of marketable investment securities and deposited $51$427 million of cash with the Corporation to secure the fair value of contracts in an unrealized gain position,

Table of Contents

Comerica Incorporated and Subsidiaries

and the Corporation had pledged $21$59 million of marketable investment securities and posted $10$26 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 no0 derivative instruments with credit-risk-related contingent features that were in a liability position at June 30, 2019.March 31, 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.

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 no0 net gains or losses in other noninterest income in the Consolidated Statements of Comprehensive Income for both the three- and six-monththree-month periods ended June 30, 2019March 31, 2020 and 2018.

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.

The Corporation maintains an allowance to cover probablecurrent expected credit losses inherent inon 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 $62 million and $31 million and $30 million at June 30, 2019March 31, 2020 and December 31, 2018,2019, 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 $24$51 million at both June 30, 2019March 31, 2020 and $25 million at December 31, 20182019 for probablecurrent expected credit losses inherent inon 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 $145$160 million and $136$161 million, respectively, of the $3.2 billion and $3.3 billion standby and commercial letters of credit outstanding at June 30, 2019March 31, 2020 and December 31, 2018.2019, 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 $32$33 million at June 30, 2019,March 31, 2020, including $25$23 million in deferred fees and $7$10 million in the allowance for credit losses on lending-related commitments. At December 31, 2018,2019, the comparable amounts were $34$32 million,, $28 $26 million and $6$6 million,, respectively.

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 agreementagreements for such borrowers. The Corporation manages its credit risk on the credit risk participation agreements by monitoring the creditworthiness of the borrowers, which is based on the normal credit review process as if the Corporation had it entered into the derivative instruments directly with the borrower.borrowers. The notional amount of such credit risk participation agreementagreements reflects the pro-rata share of the derivative instrument, consistent with itsthe Corporation's share of the related participated loan. As of June 30, 2019March 31, 2020 and December 31, 2018,2019, the total notional amount of the credit risk participation agreements was approximately $720$807 million and $703$786 million, respectively, and the fair value was insignificant for both periods. 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 $21$50 million and $7$20 million at June 30, 2019March 31, 2020 and December 31, 2018,2019, 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, 2019,March 31, 2020, the weighted average remaining maturity of outstanding credit risk participation agreements was 3.4 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 thatwhich 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 andat March 31, 2020 was limited to $453 million. There was no exposure to loss as a result of the Corporation's involvement in other tax credit entities at June 30, 2019 was limited to $437 million and $6 million, respectively.March 31, 2020.
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 ($166167 million at June 30, 2019March 31, 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 no0 financial or other support that was not contractually required to any of the above VIEs during the sixthree months ended June 30, 2019March 31, 2020 and 20182019.

(a)The fixed interest rates on these notes have been swapped to a variable rate and designated in a hedging relationship. Accordingly, carrying value has been adjusted to reflect the change in the fair value of the debt as a result of changes in the benchmark rate.
(b)Due on June 2, 2020.
Subordinated notes with remaining maturities greater than one year qualify as Tier 2 capital.
Comerica Bank (the Bank), a wholly-owned subsidiary of the Corporation, is a member of the FHLB, which provides short- and long-term funding to its members through advances collateralized by real estate-related assets. The interest raterates on the FHLB advances resets between four and eight weeks, based on the FHLB auction rate. At June 30, 2019,March 31, 2020, the weighted-average rate on the FHLB advances was 2.46%0.92%. 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, 2019, $17.0March 31, 2020, $17.6 billion of real estate-related loans and $5.5 billion of investment securities were pledged to the FHLB as collateral for currentoutstanding short- and long-term advances of $750 million and $3.8 billion, respectively, with an additional capacity for potential future borrowings of approximately $4.1$9.9 billion.
In the first quarter 2019, the Corporation issued $350 million of 4.00% senior notes maturing in 2029, swapped to a floating rate at 30-day LIBOR plus 129 basis points.

NOTE 11 - INCOME TAXES AND TAX-RELATED ITEMS
At June 30, 2019,March 31, 2020, net unrecognized tax benefits were $15$19 million, compared to $14$17 million at December 31, 2018.2019. The Corporation anticipates that it is reasonably possible settlements withthat final settlement of federal and state tax authoritiesissues will not result in a $1 million decrease inchange to net unrecognized tax benefits within the next twelve months. TheIncluded in accrued expenses and other liabilities on the Consolidated Balance Sheets was a liability for tax-related interest and penalties included in accrued expensesof $6 million and other liabilities was $7$8 million at both June 30, 2019on March 31, 2020 and December 31, 2018.2019, respectively.
Net deferred tax assetsliabilities were $104$13 million at June 30, 2019,March 31, 2020, compared to $166net deferred tax assets of $42 million at December 31, 2018. The $62 million decrease in2019, primarily driven by increases to deferred tax liabilities related to unrealized gains on investment securities available-for-sale and net hedging gains, partially offset by increases to deferred tax assets resulted from a decrease in deferred tax assets, duerelated to a decrease in unrealizedthe allowance for loan losses on investment securities, and an increase in deferred tax liabilities arising from cash flow hedges used to manage interest rate risk.allowance for depreciation. Included in deferred tax assets at both June 30, 2019March 31, 2020 and December 31, 20182019 were $4$3 million of state net operating loss carryforwards, which expire between 20192020 and 2028.2029. 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, 2019March 31, 2020 and December 31, 2018.2019. 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

28

Table of Contents

Comerica Incorporated and Subsidiaries

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, 2018 and Form 10-Q for2019, Comerica Bank, a wholly-owned subsidiary of the period ended March 31, 2019, the BankCorporation, 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 awardedfound for Masters, $52 millionresulting in an award against the Bank. On July 1, 2015, after an appeal filed by the Corporation,Bank, the Montana Supreme Court reversed the judgment against the CorporationBank and remanded the case for a new trial with instructions that Michigan contract law should apply and dismissing all other claims. TheIn January 2017, the case was retried, in the same district court, 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 2017,17, 2020, the court conducted a hearing on the amount of costs and the Corporation awaits a ruling.interest that Masters is entitled to recover. The court also heard argument on whether Masters is entitled to attorneys' fees, and if so how much. Its decision is pending. The Bank is considering its options, including additional appeals. Management believes that current reserves related to this case are adequate in the event of a negativean 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

27

Table of Contents

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 $4$2 million and $1 million were included in other noninterest expenses on the Consolidated Statements of Comprehensive Income for both the three-month periods ended June 30,March 31, 2020 and 2019, and 2018, and $5 million and $7 million for the six-month periods ended June 30, 2019 and 2018, 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 zero0 to approximately $35$45 million at June 30, 2019.March 31, 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.
For information regarding income tax contingencies, refer to Note 11.
NOTE 13 - BUSINESS SEGMENT INFORMATION
The Corporation has strategically aligned its operations into three3 major business segments: the Business Bank, the Retail Bank and Wealth Management.

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, 2019March 31, 2020.

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 is offering 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 is well positioned to assist business customers in accessing funds available through the Paycheck Protection Program and other lending initiatives.

Full-Year 2019 Outlook
For full-year 2019 compared to full-year 2018, management expects the following, assuming a continuation of the current economic environment and interest rates as of June 30, 2019:recessionary conditions:
Growth in average loans, reflecting an increase in Mortgage Banker Finance and support of 3 percent to 4 percent, reflecting better than expected growth incustomers' liquidity needs, including through the first half of 2019Paycheck Protection Program, partly offset by customers' reduced working capital and normal seasonality in the second half.capital expenditure needs.
DeclineGrowth in average deposits as customers conserve liquidity and receive benefits of 2 percent coincident with loan growth andeconomic stimulus programs, partly offset by customers using cash in their businesses.to meet operating needs.
GrowthDecrease in net interest income due to the net impact of 2 percent from the full-year net benefit of higherlower interest rates, growth in average loans and repositioning the securities portfolio, partially offset by higher wholesale funding, a shift in deposit mix and lower interest recoveries.
Provision for credit losses of 15 basis points to 20 basis points of total loans ($25 million to $35 million per quarter for the second half of 2019) and net charge-offs to remain low, with continued solid credit quality.
Noninterest income higher by 1 percent to 2 percent, benefiting from growth in card fees and fiduciary income, partially offset by lower derivative income and service charges on deposit accounts.
Noninterest expenses lower by 3 percent, reflecting the end of restructuring charges from the GEAR Up initiatives ($53 million in full-year 2018), FDIC insurance expense lower by $16 million from the discontinuance of the surcharge, as well as lower compensation and pension expense, partially offset by higher outside processing expenses in line with growing revenue, technology expenditures and typical inflationary pressures.loan growth.
Lower compensation driven by executive incentive compensation, partially offset by merit increases.
Stable noninterest expenses, excluding restructuring charges.Assuming average one-month LIBOR of 45 basis points and average deposit pay rates of 25 to 30 basis points, net reduction solely from lower interest rates of approximately $75 million in second quarter 2020.

Net interest income was $1.2 billion for the six months ended June 30, 2019, an increase of $70 million compared to $1.1 billion for the six months ended June 30, 2018. Net interest margin for the six months ended June 30, 2019 increased 21 basis points to 3.73 percent, from 3.52 percent for the comparable period in 2018. The increase in net interest income and margin resulted primarily from the same reasons as described in the quarterly discussion above.
For further discussion of the effects of market rates on net interest income, refer to the "Market and Liquidity Risk" section of this financial review.
Provision for Credit Losses
The provision for credit losses was $31 million for the six months ended June 30, 2019, compared to a benefit of $17 million for the six months ended June 30, 2018.
The provision for loan losses was $30 million for the six months ended June 30, 2019 compared to a $9 million benefit for the six months ended June 30, 2018. The increase in the provision primarily reflected an increase in Energy, partially offset by a decrease in general Middle Market. Net loan charge-offs increased $19 million to $44 million for the six months ended June 30, 2019, compared to $25 million for the six months ended June 30, 2018. The increase in net charge-offs was driven by increases in Energy and Corporate Banking, partially offset by decreases in general Middle Market and Small Business.
The provision for credit losses on lending-related commitments increased $9 million to an expense of $1 million for the six months ended June 30, 2019, compared to a benefit of $8 million for the six months ended June 30, 2018. The increase reflected an increase in commercial commitments. There were no lending-related commitment charge-offs for the six months ended June 30, 2019 and 2018.
An analysis of the allowance for credit losses and nonperforming assets is presented under the "Credit Risk" subheading in the "Risk Management" section of this financial review.

STRATEGIC LINES OF BUSINESS AND MARKETS
The Corporation has strategically aligned its operations into three major business segments: the Business 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 thesethe business and market segments for the three- and six-monththree-month periods ended June 30, 2019March 31, 2020 and 2018.2019.
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 2322 to the consolidated financial statements in the Corporation's 20182019 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 marketinterest rates increased,decreased, business segments, particularly those focused on generating deposits, benefited from higherwere impacted by lower FTP crediting rates on deposits in the sixthree months ended June 30, 2019March 31, 2020 compared to the same period in the prior year. Similarly, FTP charges for funding loans increaseddecreased in the sixthree months ended June 30, 2019,March 31, 2020, compared to the same period in the prior year. Additionally, the net FTP impact to a specific business or market segment is a function of the changes in that segment's balance sheet composition, primarily loan and deposit volumes. Effective January 1, 2019, the Corporation prospectively discontinued allocating an additional FTP charge for the cost of maintaining liquid assets to support potential draws on unfunded loan commitments.

The Corporation expects to continue to return capital to shareholders with a target of maintaining a common equity Tier 1 capital ratio of approximately 10 percent by the end of 2019. At June 30, 2019, the Corporation's Tier 1 capital ratio was estimated to be 10.19 percent. The timing and ultimate amount of future distributions will be subject to various factors including financial performance, capital needs and market conditions.

AIn March 2020, the Corporation suspended its share repurchase program, with a focus on deploying capital to meet customers' growing financing requirements. The Corporation will 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 80.287.2 million shares have been authorized for repurchase under the Corporation's share repurchase program since its inception in 2010.repurchase. There is no expiration date for the share repurchase program.

The Corporation expects to use capital and liquidity in a responsible way to assist customers impacted by the COVID-19 crisis with a longer-term target of attaining and maintaining a Common Equity Tier 1 (CET1) capital ratio of approximately 10 percent. At March 31, 2020, the Corporation's estimated CET1 capital ratio was 9.51 percent, a decrease of 62 basis points compared to December 31, 2019. Higher period-end loans at March 31, 2020 increased risk-weighted assets and contributed to the lower estimated CET1 capital ratio. The Corporation expects to elect recently issued regulatory relief to defer the impact of adopting the CECL model for measuring credit losses on regulatory capital, which resulted in a 10-basis-point benefit to the estimated CET1 capital ratio at March 31, 2020.
On July 22, 2019, the federal banking agencies issued a final rule that simplifies 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.  On November 13, 2019, the agencies issued a final rule that permitted early adoption of this rule for the quarter beginning January 1, 2020 rather than on April 1, 2020, as initially provided. The Corporation expects to early adopt this rule resulting in a benefit of approximately 8 basis points to the total risk-based capital ratio at March 31, 2020.

RISK MANAGEMENT
The following updated information should be read in conjunction with the "Risk Management" section on pages F-21F-20 through F-34F-33 in the Corporation's 20182019 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.
CECL at January 1, 2020
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.
CECL at March 31, 2020
The allowance for credit losses was $978 million at March 31, 2020, which increased $327 million during the first quarter of 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, which resulted in an economic slowdown with unprecedented speed and force. Oil prices decreased significantly during the first quarter as a result of an imbalance in production supply and demand, adding stress to an already reduced capital market activity. In response to the worsening situation, the Federal Reserve announced in March that it was reducing the target federal funds rate to zero to 0.25 percent, and Congress passed the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), which included an estimated $2 trillion stimulus package seeking to prevent a protracted severe economic recession in the U.S. These developments shaped the economic scenarios used by the Corporation in its calculation of the CECL estimate at March 31, 2020. The base scenario forecasted a recession with significant economic deterioration in the second quarter of 2020 before a partial recovery in third quarter 2020 and more modest recovery in subsequent quarters. 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 that resulted in a decline in gross domestic product ranging from 13 percent to

Table of Contents

33 percent in the second quarter of 2020, respectively. For certain loan portfolios deemed to have increased exposure to the current economic environment, including energy, automotive production, leveraged loans and industries considered at risk due to social distancing, management considered the more severe assumptions.
Allowance for Loan Losses
The allowance for loan losses represents management's assessmentmanagement’s estimates of probable, estimablecurrent expected credit losses inherent in the Corporation'sCorporation’s loan portfolio. The allowance forPools 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, on lending-related commitments, included in accrued expenses and other liabilities onto amortized cost balances over the Consolidated Balance Sheets, provides for probable losses inherent in lending-related commitments, including unused commitments to extend credit and standby lettersremaining contractual life of credit.
the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools. The allowance for loan losses was $657 million at June 30, 2019, comparedalso includes qualitative adjustments to $671 million at December 31, 2018, a decreasebring 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 troubled debt restructurings and are based on one of $14 million,several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or 2 percent. the present value of expected cash flows.    
As a percentage of total loans, the allowance for loan losses was 1.271.71 percent at June 30, 2019,March 31, 2020, compared to 1.341.27 percent at December 31, 2018.2019. The decreaseallocation of reserves for Energy loans increased to over 10 percent in response to the allowance for loan losses reflected the sustained solid credit quality of the portfolio. Sustained solid credit quality was reflected by nonperformingpressures on oil and gas markets described above. Nonperforming loans as a percentagewere 0.45 percent of total loans of 0.44 percent at June 30, 2019,March 31, 2020, compared to 0.460.40 percent at December 31, 2018,2019, and the allowance coverage of 2.9covered 3.8 times and 3.1 times total nonperforming assetsloans at both June 30, 2019March 31, 2020 and December 31, 2018.2019, respectively.
Allowance for Credit Losses on Lending-Related Commitments
The allowance for credit losses on lending-related commitments includes specific allowances, basedestimates current expected credit losses on individual evaluationscollective pools of certain letters of credit in a manner consistent with business loans, and allowances based on the pool of the remaining letters of credit and all unused commitments to extend credit within each internalbased on standard reserve factors, determined in a manner similar to business loans, multiplied by a probability of draw estimate based on historical experience and credit risk, rating.applied to commitment amounts. The allowance for credit losses on lending-related commitments wastotaled $62 million and $31 million and $30 million at June 30, 2019March 31, 2020 and December 31, 2018,2019, respectively.

Nonperforming Assets
Nonperforming assets include loans on nonaccrual status, TDRstroubled debt restructured loans (TDRs) which have been renegotiated to less than the original contractual rates (reduced-rate loans) and foreclosed property. TDRs include performing and nonperforming loans. Nonperformingloans, with nonperforming TDRs areon either on 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 is considered to be short-term. Under these terms, as of March 31, 2020, the Corporation had processed payment deferrals for approximately 60 obligors with an aggregate loan balance of $108 million. Through April 24, 2020, the number of obligors whose deferral request was processed increased to approximately 1,000 with an aggregate loan balance of $2.7 billion, with substantially all considered performing at the time of deferral.

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.

(a)Includes nonaccrual loans.
Loans in the Energy business line totaled $2.4$2.1 billion, or approximately 5 percent of total loans, at June 30, 2019, and $2.2 billion, or approximately 4 percent of total loans at March 31, 2020, and $2.2 billion at December 31, 2018.2019, a decrease of $107 million. Total exposure, including unused commitments to extend credit and letters of credit, was $4.7$3.7 billion and $4.5$4.3 billion at June 30, 2019March 31, 2020 and December 31, 2018,2019, 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 March 31, 2020, the Corporation had completed approximately 8 percent of the Spring borrowing base re-determinations and approximately 23 percent through April 24, 2020 resulting in average reduction to the borrowing base of 24 percent. Utilization increased to 56 percent primarily as a result of the reduction in exposure at March 31, 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 March 31, 2020, 66 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 35 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 increased to over 10 percent of the Energy portfolio at March 31, 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 $25$67 million and $33$8 million for the three- and six-monththree-month periods ended June 30,March 31, 2020 and 2019, respectively, while nonaccrual Energy loans increased $22 million to $65 million at March 31, 2020, compared to $4 million for both of the comparable periods in 2018. NonaccrualDecember 31, 2019. Criticized Energy loans increased $36$127 million to $84$493 million, at June 30, 2019. The increases in both net charge-offs and nonaccrual loans resulted from the impactor 20 percent of a decline in valuations of select liquidating assets related to Energy loans.

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 testedstress-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 prudently increased reserves for this portfolio as of March 31, 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.

Market and Liquidity Risk
Market risk represents the risk of loss due to adverse movementsmovement in market rates or prices, including interest rates, foreign exchange rates, commodity prices and equity prices. Liquidity risk represents the failurerisk that the Corporation does not have sufficient access to meet financial obligations coming due resulting from an inabilityfunds to liquidate assetsmaintain its normal operations at all times, or obtain adequate funding, anddoes not have the inabilityability to easily unwindraise or offset specific exposures without significant changes in pricing, due to inadequate market depth or market disruptions.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 analysisanalyses 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. TheIncluding the impact of interest rate swaps converting floating-rate loans to fixed, the Corporation's loan composition at June 30, 2019March 31, 2020 was 70 percent 30-day LIBOR, 6 percent other LIBOR (primarily 60-day), 156 percent prime and 918 percent fixed rate. This creates sensitivity to interest rate movements due to the imbalance between the faster repricing of the floating-rate loan portfolio and more slowly repricingversus 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. 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 casebase-case net interest income under an unchanged interest rate environment. Existing derivative instruments entered into for risk management purposes as of the reporting datebalance sheet dates are included in the analysis, but no additional hedging is forecasted. At June 30, 2019,March 31, 2020, these derivative instruments comprise interest rate swaps that convert $2.6$3.3 billion of fixed-rate medium- and long-term debt to variable rates through fair value hedges and $2.8convert $5.6 billion of variable-rate loans to fixed rates through cash flow hedges. This base casebase-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. The first scenario presents a 200 basis-point increase in short-term rates,months, resulting in an average increase or decrease in short-term interest rates of 10050 basis points over the period (+200 scenario). The second scenario presents a 200 basis-point decrease in short-term interest rate.

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 +200rising rate scenario reflects a greater decrease in deposits than we have 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, 2019March 31, 2020 and December 31, 2018,2019, 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.

Sensitivity to declining rates anddecreased due to changes in balance sheet composition.
The ultimate impact of changescomposition and limited remaining downward movement in rates depends in part on the pace at which deposits reprice (deposit beta). The scenarios shown above reflect management's expectation that deposit betas are likely to lag if interest rates decline, as they did at the recent cycle when rates began to rise. Varying the deposit beta assumption results in different estimated impacts to net interest income. For example, management estimates the annual impact to net interest income of a decline in short-term rates of 50 basis points over a 12-month period (25 basis points shock) can range between a decrease of approximately $60 million (50 percent deposit beta) to $90 million (10 percent deposit beta) depending on the deposit beta assumption.before reaching zero-percent floors.
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.

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. Key execution tasks are underway and include evaluating alternative rates and associated impacts, assessing the population of impacted contracts and ensuring necessary fallback provisions are incorporated, ensuring operational and system readiness, monitoring and mitigating overall transition risks, as well as communicating timely with internal and external stakeholders. Additionally, Comerica is a member of the Alternative Reference Rates Committee (ARRC) and assists with establishing industry guidelines and recommendations for the overall LIBOR transition. 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.

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 20182019 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, 2018,2019, 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-35F-34 through F-37F-36 in the Corporation's 20182019 Annual Report. As of the date of this report, there have been noBelow are significant changes to the Corporation's critical accounting policies or estimates.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 model, 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. 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.
In determining the allowance for credit losses for the majority of its lending portfolio, the Corporation uses standard loss factors, based on estimated probability of default for internal risk ratings and loss given default. Management applies standard reserve factors to pools of loans and lending-related commitments with similar risk characteristics, calibrates these standard loss factors using economic forecasts and incorporates qualitative adjustments. As such, the calculation of current expected credit losses is inherently subjective and requires management to exercise significant judgment.

Internal risk ratings: Standard 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 March 31, 2020 would change by approximately $10 million.

Forecasted economic variables: Historical standard 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. For first quarter 2020, management used an economic forecast that considered information available as of the end of the period, including assumptions regarding the impacts of the global coronavirus pandemic, the government stimulus package included in the CARES Act, effects of social distancing policy and current pressures on energy. The forecast anticipated significant economic deterioration during the second quarter of 2020 as part of a recession that would create severe financial stress, followed by a partial recovery during third quarter 2020 and more modest recovery in subsequent quarters for the remainder of the reasonable and supportable period.

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 more and less severe economic deteriorations in the second quarter of 2020, with varying speeds of recovery. In isolation, assuming a more prolonged recession through next year with elevated unemployment levels through the latter half of 2022, the CECL model may have resulted in a significantly higher allowance for credit losses. However, because qualitative adjustments are an integral part of the allowance methodology, the actual impact of a change in assumptions is not determinable.

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 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 March 31, 2020 primarily included adjustments for uncertainties related to forecasted economic variables and model imprecision.

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. 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 Business 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 Business Bank, the Retail Bank and Wealth Management. At March 31, 2020, goodwill totaled $635 million, including $473 million allocated to the Business 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 on an interim basis if events or changes in circumstances between annual tests suggest additional testing may be warranted to determine if goodwill might be impaired. The Corporation may elect to perform a quantitative impairment analysis, or first conduct a qualitative analysis to determine if a quantitative analysis is necessary.
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 current economic deterioration, 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 assessment, the Corporation determined that it was more likely than not that the fair value of each reporting unit exceeded its carrying value.
The analysis 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.

ITEM 1A. Risk Factors
There hasOther than as set forth below, there have been no material change in the Corporation’s risk factors as previously disclosed in our Form 10-K for the fiscal year ended December 31, 20182019 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 sharply 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 March 31, 2020. At March 31, 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 52 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.
