NOTE 1 - BASIS OF PRESENTATION AND ACCOUNTING POLICIES
Organization
The accompanying unaudited consolidated financial statements were prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation were included. The results of operations for the six months ended June 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. 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, 2020.
Defined Benefit Pension and Other Postretirement Costs
Effective January 1, 2021, the Corporation elected to change the accounting methodology for determining the market-related value of assets (MRVA) for certain classes of assets in the qualified defined benefit pension plan. The MRVA is used to calculate the Corporation's expected return on plan assets, a component of defined pension benefit cost (credit). These classes are currently comprised of the fixed income securities and private placement assets held in the portfolio, utilized by the Corporation to mitigate the impacts to financial results from changes in fair value of the pension liability. Previously, MRVA was measured using a historical five-year average fair value. Under the new methodology, the Corporation calculates MRVA using fair value of plan assets. Although both methods are permitted under U.S. GAAP, the Corporation believes the new policy is preferable for these classes of assets as it results in more timely recognition of the performance of pension assets in the results from operations.
The change in accounting methodology is applied retrospectively to all prior periods presented in the consolidated financial statements. The impact of the change to the qualified defined benefit plan on the Corporation's consolidated financial statements is as follows:

NOTE 2 – FAIR VALUE MEASUREMENTS
The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Corporation uses present value techniques and other valuation methods to estimate the fair values of its financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.
Investment securities available-for-sale, derivatives, deferred compensation plans and equity securities with readily determinable fair values (primarily money market mutual funds) are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as impaired loans, 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, 2020 for further information about the fair value hierarchy, descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis.

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis
The Corporation may be required to record certain assets and liabilities at fair value on a nonrecurring basis. These include assets that are recorded at the lower of cost or fair value, and were recognized at fair value since it was less than cost at the end of the period.
The following table presents assets recorded at fair value on a nonrecurring basis at June 30, 2021 and December 31, 2020. No liabilities were recorded at fair value on a nonrecurring basis at June 30, 2021 and December 31, 2020.

Level 3 assets recorded at fair value on a nonrecurring basis at June 30, 2021 and December 31, 2020 included both nonaccrual loans and TDRs for which a specific allowance was established based on the fair value of collateral. The unobservable inputs were the additional adjustments applied by management to the appraised values to reflect such factors as non-current appraisals and revisions to estimated time to sell. These adjustments are determined based on qualitative judgments made by management on a case-by-case basis and are not quantifiable inputs, although they are used in the determination of fair value.

Estimated Fair Values of Financial Instruments Not Recorded at Fair Value on a Recurring Basis
The Corporation typically holds the majority of its financial instruments until maturity and thus does not expect to realize many of the estimated fair value amounts disclosed. The disclosures also do not include estimated fair value amounts for items that are not defined as financial instruments, but which have significant value. These include such items as core deposit intangibles, the future earnings potential of significant customer relationships and the value of trust operations and other fee generating businesses. The Corporation believes the imprecision of an estimate could be significant.
The carrying amount and estimated fair value of financial instruments not recorded at fair value in their entirety on a recurring basis on the Corporation’s Consolidated Balance Sheets are as follows:

Unrealized losses resulted from changes in market interest rates and liquidity. The Corporation’s portfolio is comprised of securities issued or guaranteed by the U.S. government or government-sponsored enterprises. As such, it is expected that the securities would not be settled at a price less than the amortized cost of the investments. Further, the Corporation does not intend to sell the investments, and it is not more likely than not that it will be required to sell the investments before recovery of amortized costs. At June 30, 2021, the Corporation had 139 securities in an unrealized loss position with no allowance for credit losses, comprised of 19 U.S. Treasury securities and 120 residential mortgage-backed securities.
Interest receivable on investment securities totaled $20 million at June 30, 2021 and $18 million at December 31, 2020 and was included in accrued income and other assets on the Consolidated Balance Sheets.
Sales, calls and write-downs of investment securities available-for-sale resulted in the following losses recorded in net securities gains on the Consolidated Statements of Comprehensive Income, computed based on the adjusted cost of the specific security.

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

Included in the contractual maturity distribution in the table above were residential mortgage-backed securities with a total amortized cost of $11.9 billion and a fair value of $12.0 billion. The actual cash flows of mortgage-backed securities may differ as borrowers of the underlying loans may exercise prepayment options.
At June 30, 2021, investment securities with a carrying value of $4.0 billion were pledged where permitted or required by law, including $3.2 billion pledged to the Federal Home Loan Bank (FHLB) as collateral for potential future borrowings of approximately $3.1 billion and $830 million to secure $631 million of liabilities, primarily public and other deposits of state and local government agencies as well as derivative instruments.

(a)Includes all loans not included in the categories of special mention, substandard or nonaccrual.
(b)Includes Small Business Administration Paycheck Protection Program (PPP) loans of $1.0 billion and $1.8 billion in 2021 and 2020, respectively, at June 30, 2021, and PPP loans of $3.5 billion in 2020 at December 31, 2020.
(c)Includes loans with an internal rating of special mention, substandard loans for which the accrual of interest has not been discontinued and nonaccrual loans. Special mention loans have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. Accruing substandard loans have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans are also distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies on page F-59 in the Corporation's 2020 Annual Report. These categories are generally consistent with the "special mention" and "substandard" categories as defined by regulatory authorities. A minority of nonaccrual loans are consistent with the "doubtful" category.

Loan interest receivable totaled $135 million and $141 million at June 30, 2021 and December 31, 2020, respectively, and was included in accrued income and other assets on the Consolidated Balance Sheets.

(a)Primarily represents loan balances where terms were extended by more than an insignificant time period, typically more than 180 days, at or above contractual interest rates. Also includes commercial loans restructured in bankruptcy.
(b)Includes bankruptcy loans for which the court has discharged the borrower's obligation and the borrower has not reaffirmed the debt.
(c)Primarily loans secured by owner-occupied real estate.
The Corporation charges interest on principal balances outstanding during deferral periods. Additionally, none of the modifications involved forgiveness of principal. There were no commitments to lend additional funds to borrowers whose terms have been modified in TDRs at June 30, 2021 and December 31, 2020. 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. Loans with terms extended by more than an insignificant time period in accordance with the provisions of the CARES Act, primarily retail loans, were $42 million at June 30, 2021 and not reported as TDRs.
For principal deferrals, incremental deterioration in the credit quality of the loan, represented by a downgrade in the risk rating of the loan, for example, due to missed interest payments or a reduction of collateral value, is considered a subsequent default. For interest rate reductions, a subsequent payment default is defined in terms of delinquency, when a principal or interest payment is 90 days past due. Of the TDRs modified during the twelve-month periods ended June 30, 2021 and 2020, there were no subsequent defaults of principal deferrals or interest rate reductions in the three- and six-month periods ended June 30, 2021, compared to $6 million and $15 million of principal deferrals and no interest rate reductions in the comparable period in 2020.

NOTE 5 - DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS
In the normal course of business, the Corporation enters into various transactions involving derivative and credit-related financial instruments to manage exposure to fluctuations in interest rate, foreign currency and other market risks and to meet the financing needs of customers (customer-initiated derivatives). These financial instruments involve, to varying degrees, elements of market and credit risk. Market and credit risk are included in the determination of fair value.
Market risk is the potential loss that may result from movements in interest rates, foreign currency exchange rates or energy commodity prices that cause an unfavorable change in the value of a financial instrument. The Corporation manages this risk by establishing monetary exposure limits and monitoring compliance with those limits. Market risk inherent in interest rate and energy contracts entered into on behalf of customers is mitigated by taking offsetting positions, except in those circumstances when the amount, tenor and/or contract rate level results in negligible economic risk, whereby the cost of purchasing an offsetting contract is not economically justifiable. The Corporation mitigates most of the inherent market risk in foreign exchange contracts entered into on behalf of customers by taking offsetting positions and manages the remainder

through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and positions are monitored quarterly. Market risk inherent in derivative instruments held or issued for risk management purposes is typically offset by changes in the fair value of the assets or liabilities being hedged.
Credit risk is the possible loss that may occur in the event of nonperformance by the counterparty to a financial instrument. The Corporation attempts to minimize credit risk arising from customer-initiated derivatives by evaluating the creditworthiness of each customer, adhering to the same credit approval process used for traditional lending activities and obtaining collateral as deemed necessary. Derivatives with dealer counterparties are either cleared through a clearinghouse or settled directly with a single counterparty. For derivatives settled directly with dealer counterparties, the Corporation utilizes counterparty risk limits and monitoring procedures as well as master netting arrangements and bilateral collateral agreements to facilitate the management of credit risk. Master netting arrangements effectively reduce credit valuation adjustments 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, 2021, counterparties with bilateral collateral agreements deposited $17 million of cash with the Corporation to secure the fair value of contracts in an unrealized gain position, and the Corporation had pledged $40 million of marketable investment securities and posted $544 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.
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.

Risk Management
The Corporation's derivative instruments used for managing interest rate risk include cash flow hedging strategies that convert variable-rate loans to fixed rates and fair value hedging strategies that convert fixed-rate long-term debt to variable rates. Interest and fees on loans included $24 million and $19 million of cash flow hedge income for the three-month periods ended June 30, 2021 and 2020, respectively, and $48 million and $22 million for the six-month periods ended June 30, 2021 and 2020, respectively. In the second quarter of 2021, interest rate swap agreements with a notional amount of $300 million outstanding as of December 31, 2020 matured.

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 did not recognize any gains or losses for either the three- and six-month periods ended June 30, 2021 or 2020.
Fair values of customer-initiated and other derivative instruments represent the net unrealized gains or losses on such contracts and are recorded on the Consolidated Balance Sheets. Changes in fair value are recognized on the Consolidated Statements of Comprehensive Income. The net gains recognized in income on customer-initiated derivative instruments, net of the impact of offsetting positions included in derivative income, were as follows:

Credit-Related Financial Instruments
The Corporation issues off-balance sheet financial instruments in connection with commercial and consumer lending activities. The Corporation’s credit risk associated with these instruments is represented by the contractual amounts indicated in the following table.
(in millions)June 30, 2021December 31, 2020
Unused commitments to extend credit:
Commercial and other$25,676 $23,443 
Bankcard, revolving check credit and home equity loan commitments3,394 3,297 
Total unused commitments to extend credit$29,070 $26,740 
Standby letters of credit$3,433 $3,273 
Commercial letters of credit40 30 
The Corporation maintains an allowance to cover current expected credit losses inherent in 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 $31 million and $44 million at June 30, 2021 and December 31, 2020, 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 $28 million at June 30, 2021 and $37 million at December 31, 2020 for expected credit losses inherent in 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. There were $3.5 billion standby and commercial letters of credit outstanding at June 30, 2021 and $3.3 billion at December 31, 2020, of which these risk participations covered $144 million and $150 million, 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 $31 million at June 30, 2021 and consisted of $28 million in deferred fees and $3 million in the allowance for credit losses on lending-related commitments. At December 31, 2020, the comparable amounts were $37 million, $30 million and $7 million, respectively.

The following table presents a summary of criticized standby and commercial letters of credit at June 30, 2021 and December 31, 2020. The Corporation's criticized list is generally consistent with the Special Mention, Substandard and Doubtful categories defined by regulatory authorities. The Corporation manages credit risk through underwriting, periodically reviewing and approving its credit exposures using Board committee approved credit policies and guidelines.

Other Credit-Related Financial Instruments
The Corporation enters into credit risk participation agreements, under which the Corporation assumes credit exposure associated with a borrower’s performance related to certain interest rate derivative contracts. The Corporation is not a party to the interest rate derivative contracts and only enters into these credit risk participation agreements in instances in which the Corporation is also a party to the related loan participation agreements for such borrowers. The Corporation manages 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 entered into the derivative instruments directly with the borrowers. The notional amount of such credit risk participation agreements reflects the pro-rata share of the derivative instrument, consistent with its share of the related participated loan. As of June 30, 2021 and December 31, 2020, the total notional amount of the credit risk participation agreements was approximately $1.0 billion and $1.1 billion, respectively, and the fair value was $1 million at June 30, 2021 and $3 million at December 31, 2020. 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 $41 million and $62 million at June 30, 2021 and December 31, 2020, 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, 2021, the weighted average remaining maturity of outstanding credit risk participation agreements was 4.25 years.

NOTE 6 - VARIABLE INTEREST ENTITIES (VIEs)
The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE and whether the Corporation is the primary beneficiary and should consolidate the entity based on the variable interests it held both at inception and when there is a change in circumstances that requires a reconsideration.
The Corporation holds ownership interests in funds in the form of limited partnerships or limited liability companies (LLCs) investing in affordable housing projects that qualify for the low-income housing tax credit (LIHTC). The Corporation also directly invests in limited partnerships and LLCs which invest in community development projects, which generate similar tax credits to investors (other tax credit entities). As an investor, the Corporation obtains income tax credits and deductions from the operating losses of these tax credit entities. These tax credit entities meet the definition of a VIE; however, the Corporation is not the primary beneficiary of the entities, as the general partner or the managing member has both the power to direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses or the right to receive benefits that could be significant to the entities.
The Corporation accounts for its interests in LIHTC entities using the proportional amortization method. Ownership interests in other tax credit entities are accounted for under either the cost or equity method. Exposure to loss as a result of the Corporation's involvement in LIHTC entities and other tax credit entities at June 30, 2021 was limited to $452 million and $12 million, respectively.
Investment balances, including all legally binding commitments to fund future investments, are included in accrued income and other assets on the Consolidated Balance Sheets. A liability is recognized in accrued expenses and other liabilities on the Consolidated Balance Sheets for all legally binding unfunded commitments to fund tax credit entities ($164 million at June 30, 2021). Amortization and other write-downs of LIHTC investments are presented on a net basis as a component of the provision for income taxes on the Consolidated Statements of Comprehensive Income, while amortization and write-downs of other tax credit investments are recorded in other noninterest income. The income tax credits and deductions are recorded as a reduction of income tax expense and a reduction of federal income taxes payable.
The Corporation provided no financial or other support that was not contractually required to any of the above VIEs during the six months ended June 30, 2021 and 2020.

(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.
    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 rates on the FHLB advances resets between four and eight weeks, based on the FHLB auction rate. Each note may be prepaid in full, without penalty, at each scheduled reset date. The Bank held no outstanding long-term advances at June 30, 2021. Borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At June 30, 2021, $18.5 billion of real estate-related loans and $3.2 billion of investment securities were pledged to the FHLB as collateral with capacity for potential future borrowings of approximately $11.9 billion.
    Unamortized debt issuance costs deducted from the carrying amount of medium- and long-term debt totaled $8 million at June 30, 2021 and $10 million at December 31, 2020.

NOTE 11 - INCOME TAXES AND TAX-RELATED ITEMS
At June 30, 2021, net unrecognized tax benefits were $20 million, compared to $19 million at December 31, 2020. The Corporation anticipates that it is reasonably possible that final settlement of federal and state tax issues will result in a change in net unrecognized tax benefits of $6 million within the next twelve months. Included in accrued expenses and other liabilities on the Consolidated Balance Sheets was a liability for tax-related interest and penalties of $6 million at both June 30, 2021 and December 31, 2020.
Net deferred tax liabilities were $10 million at June 30, 2021, compared to $4 million of net deferred tax assets at December 31, 2020. The $14 million decrease resulted from a decrease to deferred tax assets related to the allowance for loan losses and an increase to deferred tax liabilities related to defined benefit plans that was partially offset by decreases to deferred tax liabilities related to unrealized losses on investment securities available-for-sale as well as hedging gains and losses and an increase to deferred tax assets related to defined benefit plan components of OCI. Included in deferred tax assets at both June 30, 2021 and December 31, 2020 were $3 million of state net operating loss carryforwards, which expire between 2021

and 2030. 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, 2021 and December 31, 2020. The determination regarding valuation allowance was based on evidence of loss carryback capacity, projected future reversals of existing taxable temporary differences to absorb the deferred tax assets and assumptions made regarding future events.
In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) or other tax jurisdictions may review and/or challenge specific interpretive tax positions taken by the Corporation with respect to those transactions. The Corporation believes its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The IRS or other tax jurisdictions, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law.
Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that current tax reserves are adequate, and the amount of any potential incremental liability arising is not expected to have a material adverse effect on the Corporation’s consolidated financial condition or results of operations. Probabilities and outcomes are reviewed as events unfold, and adjustments to the reserves are made when necessary.

NOTE 12 - CONTINGENT LIABILITIES
Legal Proceedings and Regulatory Matters
As previously reported in the Corporation's Form 10-K for the year ended December 31, 2020 and Form 10-Q for the period ended March 31, 2021, the Bank appealed a court's decision in Butte Local Development v. Masters Group v. Comerica Bank, for lender liability. On July 6, 2021, the Montana Supreme Court affirmed in part, reversed in part the trial court's judgment in favor of Masters. The court reduced the amount of the award by $8 million. Additionally, in second quarter 2021, the Corporation agreed to a proposed settlement in connection with a class action lawsuit filed in the U.S. District Court in California and a related Trustee claim pending in the U.S. Bankruptcy Court in Delaware. Upon final settlement and court approval, the Corporation expects to be released from any liability for additional litigation or claims. The estimated net impact of this settlement, including the Corporation's insurance coverage, was $15 million and included in other noninterest expenses. The Corporation has accrued the estimated probable loss for these two matters within accrued expenses and other liabilities.
The Corporation and certain of its subsidiaries are subject to various other pending or threatened legal proceedings arising out of the normal course of business or operations. The Corporation believes it has meritorious defenses to the claims asserted against it in its other currently outstanding legal proceedings and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interests of the Corporation and its shareholders. Settlement may result from the Corporation's determination that it may be more prudent financially to settle, rather than litigate, and should not be regarded as an admission of liability.
Further, from time to time, the Corporation is also subject to examinations, inquiries and investigations by regulatory authorities in areas including, but not limited to, compliance, risk management and consumer protection, which could lead to administrative or legal proceedings or settlements. Remedies in these proceedings or settlements may include fines, penalties, restitution or alterations in the Corporation's business practices and may result in increased operating expenses or decreased revenues.
On at least a quarterly basis, the Corporation assesses its potential liabilities and contingencies in connection with outstanding legal proceedings and regulatory matters utilizing the latest information available. On a case-by-case basis, accruals are established for those legal claims and regulatory matters for which it is probable that a loss will be incurred and the amount of such loss can be reasonably estimated. The actual costs of resolving these claims and regulatory matters may be substantially higher or lower than the amounts accrued. Based on current knowledge, and after consultation with legal counsel, management believes current accruals 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.
For matters where a loss is not probable, the Corporation has not established an accrual. The Corporation believes the estimate of the aggregate range of reasonably possible losses, in excess of established accruals, for all legal proceedings and regulatory matters in which it is involved is from zero to approximately $48 million at June 30, 2021. This estimated aggregate range of reasonably possible losses is based upon currently available information for those legal proceedings and regulatory matters in which the Corporation is involved, taking into account the Corporation’s best estimate of such losses for those legal cases and regulatory matters for which such estimate can be made. For certain legal cases and regulatory matters, the
27

Corporation does not believe that an estimate can currently be made. The Corporation’s estimate involves significant judgment, given the varying stages of the legal proceedings and regulatory matters (including the fact many are currently in preliminary stages), the existence in certain legal 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 legal proceedings and regulatory matters (including issues regarding class certification and the scope of many of the claims) and the attendant uncertainty of the various potential outcomes of such legal proceedings and regulatory matters. 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 - STRATEGIC LINES OF BUSINESS AND MARKETS
The Corporation has strategically aligned its operations into three major business segments: the Commercial Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. Business segment results are produced by the Corporation’s internal management accounting system. This system measures financial results based on the internal business unit structure of the Corporation. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. The management accounting system assigns balance sheet and income statement items to each business segment using certain methodologies, which are regularly reviewed and refined. From time to time, the Corporation may make reclassifications among the segments to more appropriately reflect management's current view of the segments, and methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines. For comparability purposes, amounts in all periods are based on business unit structure and methodologies in effect at June 30, 2021.
The following discussion provides information about the activities of each business segment. A discussion of the financial results and the factors impacting performance can be found in "Business Segments" in the "Strategic Lines of Business and Markets" section of the financial review.
The Commercial Bank meets the needs of small and middle market businesses, multinational corporations and governmental entities by offering various products and services including commercial loans and lines of credit, deposits, cash management, capital market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services.
The Retail Bank includes a full range of personal financial services, consisting of consumer lending, consumer deposit gathering and mortgage loan origination. This business segment offers a variety of consumer products including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit and residential mortgage loans. In addition, this business segment offers a subset of commercial products and services to micro-businesses whose primary contact is through the branch network.
Wealth Management offers products and services consisting of fiduciary services, private banking, retirement services, investment management and advisory services, investment banking and brokerage services. This business segment also offers the sale of annuity products, as well as life, disability and long-term care insurance products.
The Finance segment includes the Corporation’s securities portfolio and asset and liability management activities. This segment is responsible for managing the Corporation’s funding, liquidity and capital needs, performing interest sensitivity analysis and executing various strategies to manage the Corporation’s exposure to liquidity, interest rate risk and foreign exchange risk.
The Other category includes the income and expense impact of equity and cash, tax benefits not assigned to specific business segments, charges of an unusual or infrequent nature that are not reflective of the normal operations of the business segments and miscellaneous other expenses of a corporate nature.
For further information on the methodologies which form the basis for these results refer to Note 22 to the consolidated financial statements in the Corporation's 2020 Annual Report.

Factors that could cause or contribute to such differences include credit risks (unfavorable developments concerning credit quality; declines or other changes in the businesses or industries of the Corporation's customers, in particular the energy industry; and changes in customer behavior); market risks (changes in monetary and fiscal policies; fluctuations in interest rates and their impact on deposit pricing; and transitions away from LIBOR towards new interest rate benchmarks); liquidity risks (the Corporation's ability to maintain adequate sources of funding and liquidity; reductions in the Corporation's credit rating; and the interdependence of financial service companies); technology risks (cybersecurity risks and heightened legislative and regulatory focus on cybersecurity and data privacy); operational risks (operational, systems or infrastructure failures; reliance on other companies to provide certain key components of business infrastructure; the impact of legal and regulatory proceedings or determinations; losses due to fraud; and controls and procedures failures); compliance risks (changes in regulation or oversight; the effects of stringent capital requirements; and the impacts of future legislative, administrative or judicial changes to tax regulations); strategic risks (damage to the Corporation's reputation; the Corporation's ability to utilize technology to efficiently and effectively develop, market and deliver new products and services; competitive product and pricing pressures among financial institutions within the Corporation's markets; the implementation of the Corporation's strategies and business initiatives; management's ability to maintain and expand customer relationships; management's ability to retain key officers and employees; and any future strategic acquisitions or divestitures); and other general risks (impacts from the COVID-19 global pandemic; changes in general economic, political or industry conditions; the effectiveness of methods of reducing risk exposures; the effects of catastrophic events; changes in accounting standards and the critical nature of the Corporation's accounting policies; and the volatility of the Corporation's stock price). The Corporation cautions that the foregoing list of factors is not all-inclusive. For discussion of factors that may cause actual results to differ from expectations, please refer to our filings with the Securities and Exchange Commission. In particular, please refer to “Item 1A. Risk Factors” beginning on page 13 of the Corporation's Annual Report on Form 10-K for the year ended December 31, 2020. Forward-looking statements speak only as of the date they are made.

RESULTS OF OPERATIONS
Three Months Ended June 30, 2021 compared to Three Months Ended June 30, 2020
Net income for the three months ended June 30, 2021 was $328 million, compared to $118 million for the three months ended June 30, 2020. The $210 million increase in net income was driven by lower provision for credit losses, which reflected the economy re-opening as well as improvements in the economic forecast and in the Energy portfolio since the onset of the pandemic last year, as well as a decline in criticized loans. Higher noninterest expenses and lower net interest income were partially offset by an increase in noninterest income. Net income per diluted common share was $2.32 and $0.84 for the three months ended June 30, 2021 and 2020, respectively, an increase of $1.48 per diluted common share.
Effective January 1, 2021, the Corporation elected to change the accounting methodology for determining market-related value of plan assets (MRVA) for certain classes of assets in the qualified defined benefit pension plan. The impact of the change for the three months ended June 30, 2021 was an increase to the pension benefit reduction to noninterest expenses of $5 million and a corresponding increase to net income of $4 million. The change in accounting methodology is applied retrospectively to all prior periods presented in the consolidated financial statements. Discussion of results of operations is based on recast results. See Note 1 to the consolidated financial statements for further information and impacts of the change in accounting policy.

Net interest income was $465 million for the three months ended June 30, 2021, a decrease of $6 million compared to $471 million for the three months ended June 30, 2020. The decrease in net interest income was driven by lower loan volume and the impact of an increase in lower-yielding investment securities, partially offset by lower rates paid on interest-bearing deposits and reduced borrowing volume. Net interest margin was 2.29 percent for the three months ended June 30, 2021, a decline of 21 basis points from 2.50 percent for the three months ended June 30, 2020. Average earning assets increased $5.5 billion, due to increases of $6.4 billion in interest-bearing deposits with banks and $2.8 billion in investment securities, partially offset by a $3.7 billion decrease in loans. Average interest-bearing funding sources decreased $1.6 billion, reflecting a $4.3 billion decrease in medium- and long-term debt and an $880 million decrease in short-term borrowings, partially offset by a $3.6 billion increase in interest-bearing deposits.
Provision for Credit Losses
    The provision for credit losses, which includes the provision for loan losses and the provision for credit losses on lending-related commitments, was a benefit of $135 million for the three months ended June 30, 2021, compared to an expense of $138 million for the three months ended June 30, 2020. The change in the provision for credit losses reflected the economy re-opening as well as improvements in the economic forecast and in the Energy portfolio since the onset of the pandemic last year, as well as a decline in criticized loans. Net loan recoveries were $11 million for the three months ended June 30, 2021, compared to net loan charge-offs of $50 million, or 37 basis points of average total loans for the three months ended June 30, 2020, primarily driven by a decrease in Energy net charge-offs of $57 million to a net recovery of $12 million for the three months ended June 30, 2021.
    An analysis of the allowance for credit losses and a summary of nonperforming assets are presented under the "Credit Risk" subheading in the "Risk Management" section of this financial review.

Prior periods have been adjusted to conform to this presentation and the changes in presentation do not impact total noninterest income.
(b)The table below provides further details on certain categories included in other noninterest income.
    Noninterest income increased $37 million to $284 million for the three months ended June 30, 2021, reflecting an increase in card fees as a result of higher activity including from stimulus payments, as well as increases in fiduciary income, syndication agent fees (component of commercial lending fees), service charges on deposit accounts and derivative income. Noninterest income was also impacted by a decrease in other noninterest income, as detailed below, driven by lower securities trading income, partially offset by higher deferred compensation asset returns (offset in other noninterest expenses).

(a)    The three months ended June 30, 2020 have been recast to reflect the retrospective application of the Corporation's election to change the accounting method for certain components of expense related to the defined pension plan, resulting in a decrease of $6 million from the previously reported balances. See Note 1 to the consolidated financial statements for further information and impacts of the change in accounting policy.
Noninterest expenses increased $29 million to $463 million, primarily reflecting increases in salaries and benefits expense and outside processing fee expense, partially offset by a decrease in other noninterest expenses. The increase in salaries and benefits expense was mostly a result of lower performance-related compensation in 2020 due to the expected impact to performance from the COVID-19 pandemic, as well as the impact of annual merit increases. Higher technology-related labor costs (related to contract labor), staff insurance (from elevated claims) and deferred compensation expense (offset in other

noninterest income) also contributed to the increase in salaries and benefits expense. The increase in outside processing fee expense was primarily due to higher volumes of government card transactions (tied to card fee revenue) and data processing support for PPP loans, while the decrease in other noninterest expense was driven by lower non-salary pension expense and operational losses, partially offset by higher litigation-related expenses.
Six Months Ended June 30, 2021 compared to Six Months Ended June 30, 2020
Net income for the six months ended June 30, 2021 was $678 million, an increase of $619 million compared to $59 million for the six months ended June 30, 2020. The increase was driven by lower provision for credit losses and higher noninterest income, partially offset by a decrease in net interest income and higher noninterest expenses. For the six months ended June 30, 2021, net income per diluted common share was $4.76, an increase of $4.34 compared to $0.42 for the six months ended June 30, 2020.
Effective January 1, 2021, the Corporation elected to change the accounting methodology for determining MRVA for certain classes of assets in the qualified defined benefit pension plan. The impact of the change for the six months ended June 30, 2021 was an increase to the pension benefit reduction to noninterest expenses of $9 million and a corresponding increase to net income of $7 million. The change in accounting methodology is applied retrospectively to all prior periods presented in the consolidated financial statements. Discussion of results of operations is based on recast results. See Note 1 to the consolidated financial statements for further information and impacts of the change in accounting policy.

Net interest income was $908 million for the six months ended June 30, 2021, a decrease of $76 million compared to $984 million for the six months ended June 30, 2020. The decrease in net interest income reflected lower yields on earning assets, partially offset by lower rates paid on deposits and debt. Net interest margin was 2.29 percent for the six months ended June 30, 2021, a decrease of 48 basis points compared to 2.77 percent for the comparable period in 2020. The decrease in net interest margin reflected the decline in the average 30-day LIBOR, from 0.88 percent for the six months ended June 30, 2020 to 0.11 percent for the six months ended June 30, 2021. Average earning assets increased $8.3 billion, due to increases of $6.9 billion in interest-bearing deposits with banks and $2.7 billion in investment securities, partially offset by a small decrease in loans. Average interest-bearing funding sources decreased $743 million, reflecting a $4.0 billion decrease in medium- and long-term debt and a $517 million decrease in short-term borrowings, partially offset by a $3.8 billion increase in interest-bearing deposits.
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 a benefit of $317 million for the six months ended June 30, 2021, compared to an expense of $549 million for the six months ended June 30, 2020. The change in provision for credit losses reflected the economy re-opening as well as improvements in the economic forecast and in the Energy portfolio since the onset of the pandemic last year. Net loan recoveries were $8 million for the six months ended June 30, 2021, compared to net loan charge-offs of $134 million for the six months ended June 30, 2020, largely driven by a decrease of $125 million in Energy net charge-offs.
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.

(b)The table below provides further details on certain categories included in other noninterest income.
    Noninterest income increased $70 million to $554 million, including increases in card fees, derivative income and fiduciary income, as well as increases in syndication agent fees and loan commitment fees (both components of commercial lending fees). The increase in card fees resulted from higher activity mostly related to stimulus payments, while the increase in derivative income was primarily due to favorable valuation adjustments, partially offset by a decrease in interest rate swap activity. Noninterest income was also impacted by an increase in other noninterest income, as detailed below, driven by increases in deferred compensation asset returns (offset in noninterest expenses) and income from principal investing and warrants, partially offset by lower securities trading income.

expense reflected lower performance-related compensation in 2020, including stock-based compensation, due to the expected impact to performance from the COVID-19 pandemic. Higher deferred compensation expense (offset in other noninterest income), technology-related labor costs (related to contract labor) and staff insurance (from elevated claims) also contributed to the increase in salaries and benefits expense.

Solid loan growth in nearly all business lines (excluding PPP), more than offset by forgiveness of the bulk of PPP loans.
Average deposits
Deposits to remain strong.
Net interest income
Net interest income reflects benefit of higher loan volume (excluding PPP loans) and additional days, more than offset by the impact from lower PPP loans.
Credit quality
Strong credit quality continues.
Noninterest income
Growth in customer-related fees due to rebounding economic activity, more than offset by lower card fees (decrease in stimulus activity), fiduciary (annual tax preparation fees in second quarter) and deferred compensation from elevated levels.
Noninterest expenses
Increases in seasonal expenses and technology investments, more than offset by lower litigation-related expenses and deferred compensation from elevated levels.
Tax rate
Income tax expense for full-year 2021 to be between 22 and 23 percent of pre-tax income, excluding discrete items.
Capital
Continue share repurchases; CET1 target of approximately 10 percent.
STRATEGIC LINES OF BUSINESS AND MARKETS
The Corporation has strategically aligned its operations into three major business segments: the Commercial Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. The Other category includes items not directly associated with the business segments or the Finance segment. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. Market segment results are also provided for the Corporation's three primary geographic markets: Michigan, California and Texas. In addition to the three primary geographic markets, Other Markets is also reported as a market segment. Note 13 to the consolidated financial statements describes the business activities of each business segment and presents financial results of the business and market segments for the three- and six-month periods ended June 30, 2021 and 2020.
The Corporation's management accounting system assigns balance sheet and income statement items to each segment using certain methodologies, which are regularly reviewed and refined. These methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines. Note 22 to the consolidated financial statements in the Corporation's 2020 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 on deposits and other funds provided reflect the long-term value of deposits and other funding sources based on their implied maturities. Due to the longer-term nature of implied maturities, FTP crediting rates are generally

Table of Contents
less volatile than changes in interest rates observed in the market. 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. As a result of applying matched funding, interest revenue for each segment resulting from loans and other assets is generally not impacted by changes in interest rates. Therefore, net interest income for each segment primarily reflects the volume of loans and other earning assets at the spread over the matched cost of funds, as well as the volume of deposits at the associated FTP crediting rates. Due to the impact of lower interest rates, business segments, particularly those focused on generating deposits, were impacted by lower FTP crediting rates on deposits in the six months ended June 30, 2021 compared to the same period in the prior year. Similarly, FTP charges for funding loans decreased in the six months ended June 30, 2021, compared to the same period in the prior year.
Business Segments
The following sections present a summary of the performance of each of the Corporation's business segments for the six months ended June 30, 2021 compared to the same period in the prior year. The six months ended June 30, 2021 has been recast to reflect the retrospective application of the Corporation's election to change the accounting method for certain components of expense related to the defined pension plan. Further information about the change in accounting methodology is presented in Note 1 to the consolidated financial statements.

FINANCIAL CONDITION
Second Quarter 2021 Compared to Fourth Quarter 2020
Period-End Balances
Total assets increased $226 million to $88.4 billion, driven by increases of $809 million in investment securities to deploy excess liquidity and $757 million in interest-bearing deposits with banks, partially offset by a decrease of $1.8 billion in net loans. The decline in loans includes a $1.5 billion decline in National Dealer Services as a result of low inventories as well as a $677 million decline in Mortgage Banker Finance from elevated activity in 2020. PPP loans decreased $663 million to $2.8 billion, reflecting repayments of $1.7 billion, primarily through the forgiveness process.
Total liabilities increased $345 million to $80.4 billion, primarily reflecting a decrease of $2.9 billion in medium- and long-term debt, which was more than offset by increases of $2.1 billion in interest-bearing deposits and $1.1 billion in noninterest-bearing deposits. The decrease in medium- and long-term was driven by the repayment of $2.8 billion in floating-rate Federal Home Loan Bank (FHLB) advances during the first quarter. The deposit growth reflected increases in nearly every business line as commercial customers generated increased cash, while consumer customers continued to conserve cash from government stimulus payments.
Average Balances
Total assets increased $2.5 billion to $87.9 billion due to increases of $3.0 billion in interest-bearing deposits with banks and $517 million in investment securities, as well as smaller increases in other assets, partially offset by a $1.6 billion decrease in loans.

The Corporation resumed share repurchases under the share repurchase program during the second quarter of 2021, including a previously announced Accelerated Share Repurchase transaction (ASR). On April 27, 2021 the Corporation's Board of Directors approved the authorization to repurchase up to an additional 10 million shares of its outstanding common stock, including the ASR. Since the inception of the share repurchase program in 2010, a total of 97.2 million shares have been authorized for repurchase. There is no expiration date for the share repurchase program. The timing and actual amount of additional share repurchases are subject to various factors, including the Corporation's earnings generation, capital needs to fund future loan growth and market conditions.
The Corporation continues to target a common equity Tier 1 capital ratio of approximately 10 percent with continued active capital management. At June 30, 2021, the Corporation's estimated CET1 capital ratio was 10.39 percent. In 2020, the Corporation elected regulatory relief to defer the impact of adopting the CECL model for measuring credit losses on regulatory capital. The estimated deferral amount at June 30, 2021 was reduced to zero due to a $309 million decline in the allowance for credit losses from December 31, 2020, resulting from sustained improvements in the economy and in the Corporation's credit quality.

RISK MANAGEMENT
The following updated information should be read in conjunction with the "Risk Management" section on pages F-22 through F-38 in the Corporation's 2020 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. As a percentage of total loans, the allowance for credit losses was 1.36 percent at June 30, 2021, compared to 1.90 percent at December 31, 2020. Excluding $2.8 billion in PPP loans, which are guaranteed by the Small Business Administration, the allowance for credit losses was 1.44 percent of total loans at June 30, 2021, compared to 2.03 percent at December 31, 2020. The allowance for credit losses covered 2.1 times and 2.8 times total nonperforming loans at June 30, 2021 and December 31, 2020, respectively.
The allowance for credit losses decreased $309 million to $683 million at June 30, 2021, primarily reflecting a sustained recovery by the U.S. economy from the COVID-19 pandemic and benefits of mitigating actions by the U.S. government. In addition to $2.8 trillion of stimulus spending approved by Congress between December 2020 and March 2021, the positive progress of the vaccine rollout and associated opening of the broader economy contributed to an improved economic outlook. Despite these favorable developments, there continues to be uncertainty related to emerging COVID-19 variants, supply chain and labor constraints, future monetary and fiscal actions and inflationary pressures.
These factors shaped the 2-year reasonable and supportable forecasts used by the Corporation in its CECL estimate at June 30, 2021. The U.S. economy is expected to continue to grow at an accelerated pace through 2021 before normalizing into historical growth rates in 2022. Forecasts for other key economic variables, including the unemployment rate and oil prices, are generally in line with GDP projections. Interest rates remain low, reflecting the Federal Reserve's expectation that rates will remain at current levels in the near-to mid-term, while corporate bond rates reflect normalizing default risk. The following table summarizes select economic variables representative of the economic forecasts used to develop the allowance for credit losses estimate at June 30, 2021.
Economic VariableBase Forecast
Real Gross Domestic Product (GDP) growthGrowth decreases to 5 percent by fourth quarter 2021, normalizing into a long-term growth rate of between 2 to 3 percent by the beginning of 2022.
Unemployment rateCurrent levels gradually decrease to below 4 percent by third quarter 2022.
Corporate BBB bond to 10-year Treasury bond spreadsSpreads gradually increase from current levels to 1.7 percent by the end of the forecast period.
Oil PricesPrices stable at around $60 per barrel throughout the forecast period.
Due to the high level of uncertainty regarding significant assumptions, such as the ultimate impact of the global pandemic, the Corporation evaluated a range of economic scenarios, including more benign and more severe economic forecasts. In the more severe scenario, real GDP is expected to contract through first quarter 2022, gradually improving to 4 percent by the end of the forecast period. Other key economic variables follow a similar pattern of a lagged recovery. Selecting the more severe forecast would result in an increase in the quantitative calculation of allowance for credit losses by approximately $181 million as of June 30, 2021. However, factoring in model overlays and qualitative adjustments could result in a materially different estimate under a more severe scenario.

Allowance for Loan Losses
The allowance for loan losses represents management’s estimates of current expected credit losses in the Corporation’s loan portfolio. Pools of loans with similar risk characteristics are collectively evaluated, while loans that no longer share risk characteristics with loan pools are evaluated individually.
Collective loss estimates are determined by applying reserve factors, designed to estimate current expected credit losses, to amortized cost balances over the remaining contractual life of the collectively evaluated portfolio. Loans with similar risk characteristics are aggregated into homogeneous pools. The allowance for loan losses also includes qualitative adjustments to bring the allowance to the level management believes is appropriate based on factors that have not otherwise been fully accounted for, including adjustments for foresight risk, input imprecisions and model imprecision. Credit losses for loans that no longer share risk characteristics with the loan pools are estimated on an individual basis. Individual credit loss estimates are typically performed for nonaccrual loans and modified loans classified as troubled debt restructurings (TDRs) and are based on one of several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected cash flows.    
As a percentage of total loans, the allowance for loan losses was 1.30 percent at June 30, 2021, compared to 1.81 percent at December 31, 2020. Excluding PPP loans, the allowance for loan losses was 1.37 percent of total loans at June 30, 2021, compared to 1.94% at December 31, 2020. Nonperforming loans were 0.64 percent of total loans at June 30, 2021, compared to 0.67 percent at December 31, 2020, and the allowance for loan losses covered 2.0 times and 2.7 times total nonperforming loans at June 30, 2021 and December 31, 2020, respectively.
Allowance for Credit Losses on Lending-Related Commitments
    The allowance for credit losses on lending-related commitments estimates current expected credit losses on collective pools of letters of credit and unused commitments to extend credit based on reserve factors, determined in a manner similar to business loans, multiplied by a probability of draw estimate based on historical experience and credit risk, applied to commitment amounts. The allowance for credit losses on lending-related commitments totaled $31 million and $44 million at June 30, 2021 and December 31, 2020, respectively.
    For additional information regarding the allowance for credit losses, refer to the "Critical Accounting Policies" section and pages F-57 through F-59 in Note 1 to the consolidated financial statements of the Corporation's 2020 Annual Report.
Nonperforming Assets
Nonperforming assets include loans on nonaccrual status, TDRs which have been renegotiated to less than the original contractual rates (reduced-rate loans) and foreclosed assets. TDRs include performing and nonperforming loans, with nonperforming TDRs on either nonaccrual or reduced-rate status. In accordance with the provisions of the CARES Act, the Corporation elected not to consider qualifying COVID-19-related modifications, primarily deferrals, as TDRs and does not designate such loans as past due or nonaccrual. For additional information regarding the Corporation's accounting policies for the CARES Act, refer to page F-56 in Note 1 to the consolidated financial statements of the Corporation's 2020 Annual Report.

Nonperforming assets decreased $39 million to $320 million at June 30, 2021, from $359 million at December 31, 2020. The decrease in nonperforming assets primarily reflected a $62 million decrease in nonperforming Energy loans, which are a component of commercial loans.
As of June 30, 2021, COVID-19-related payment deferrals, which consisted of residential mortgages, totaled $45 million, or 0.09 percent of total loans. Initial deferrals have expired and new requests have been nominal as customers continue to adjust to the new environment, resulting in a $42 million decrease in deferrals since first quarter 2021. Loans with COVID-19-related deferred payments on a third or later deferral, primarily residential mortgages, totaled $42 million at June 30, 2021 and would generally be considered TDRs if not for the provisions in the CARES Act.

The Corporation limits risk inherent in its commercial real estate lending activities by monitoring borrowers directly involved in the commercial real estate markets and adhering to conservative policies on loan-to-value ratios for such loans. Commercial real estate loans, consisting of real estate construction and commercial mortgage loans, totaled $14.5 billion at June 30, 2021. Of the total, $6.3 billion, or 43 percent, were to borrowers in the Commercial Real Estate business line, which includes loans to real estate developers, an increase of $337 million compared to December 31, 2020. Commercial real estate loans in other business lines totaled $8.2 billion, or 57 percent, at June 30, 2021. These loans consisted primarily of owner-occupied commercial mortgages, which bear credit characteristics similar to non-commercial real estate business loans. Generally, loans previously reported as real estate construction are classified as commercial mortgage loans upon receipt of a certificate of occupancy. During the second quarter 2021, the Corporation performed an in-depth review of the status of these loans which resulted in $1.1 billion of loans previously reported as real estate construction to be classified as commercial mortgage loans as of June 30, 2021.
The real estate construction loan portfolio primarily contains loans made to long-tenured customers with satisfactory completion experience. Criticized real estate construction loans in the Commercial Real Estate business line totaled $30 million and $27 million at June 30, 2021 and December 31, 2020, respectively. In other business lines, criticized real estate construction loans totaled $40 million at June 30, 2021, compared to $20 million at December 31, 2020. There were no real estate construction loan charge-offs in either of the six-month periods ended June 30, 2021 and 2020.
Commercial mortgage loans are loans where the primary collateral is a lien on any real property and are primarily loans secured by owner-occupied real estate. Real property is generally considered primary collateral if the value of that

collateral represents more than 50 percent of the commitment at loan approval. Loans in the commercial mortgage portfolio generally mature within three to five years. Criticized commercial mortgage loans in the Commercial Real Estate business line totaled $69 million and $73 million at June 30, 2021 and December 31, 2020, respectively. In other business lines, $338 million and $440 million of commercial mortgage loans were criticized at June 30, 2021 and December 31, 2020, respectively. Commercial mortgage loan net charge-offs were zero for the six months ended June 30, 2021, compared to net recoveries of $2 million for the same period in 2020.

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, totaled $3.4 billion at June 30, 2021. The residential real estate portfolio is principally located within the Corporation's primary geographic markets. Substantially all residential real estate loans past due 90 days or more are placed on nonaccrual status, and substantially all junior lien home equity loans that are current or less than 90 days past due are placed on nonaccrual status if full collection of the senior position is in doubt. At no later than 180 days past due, such loans are charged off to current appraised values less costs to sell.
Residential mortgages totaled $1.8 billion at June 30, 2021, and were primarily larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.8 billion of residential mortgage loans outstanding, $41 million were on nonaccrual status at June 30, 2021. The home equity portfolio totaled $1.5 billion at June 30, 2021, of which 95 percent was outstanding under primarily variable-rate, interest-only home equity lines of credit, 4 percent were in amortizing status and 1 percent were closed-end home equity loans. Of the $1.5 billion of home equity loans outstanding, $14 million were on nonaccrual status at June 30, 2021. A majority of the home equity portfolio was secured by junior liens at June 30, 2021. 
Energy Lending
The Corporation has a portfolio of Energy loans that are included entirely in commercial loans in the Consolidated Balance Sheets. Customers in the Corporation's Energy business line (approximately 120 relationships) are engaged in three segments of the oil and gas business: exploration and production (E&P), midstream and energy services. E&P generally includes such activities as searching for potential oil and gas fields, drilling exploratory wells and operating active wells. Commitments to E&P borrowers are generally subject to semi-annual borrowing base re-determinations based on a variety of factors including updated prices (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.

Leveraged Loans
Certain loans in the Corporation's commercial portfolio are considered leveraged transactions. These loans are typically used for mergers, acquisitions, business recapitalizations, refinancing and equity buyouts. To help mitigate the risk associated with these loans, the Corporation focuses on middle market companies with highly capable management teams, strong sponsors and solid track records of financial performance. Industries prone to cyclical downturns and acquisitions with a high degree of integration risk are generally avoided. Other considerations include the sufficiency of collateral, the level of balance sheet leverage and the adequacy of financial covenants. During the underwriting process, cash flows are stress-tested to evaluate the borrowers' abilities to handle economic downturns and an increase in interest rates.
The FDIC defines higher-risk commercial and industrial (HR C&I) loans for assessment purposes as loans generally with leverage of four times total debt to earnings before interest, taxes and depreciation (EBITDA) as well as three times senior debt to EBITDA, excluding certain collateralized loans.
The following table summarizes information about HR C&I loans, which represented 5 percent of total loans at both June 30, 2021 and December 31, 2020.

Market and Liquidity Risk
Market risk represents the risk of loss due to adverse movement in prices, including interest rates, foreign exchange rates, commodity prices and equity prices. Liquidity risk represents the risk that the Corporation does not have sufficient access to funds to maintain its normal operations at all times, or does not have the ability to raise or borrow funds at a reasonable cost at all times.
The Asset and Liability Policy Committee (ALCO) of the Corporation establishes and monitors compliance with the policies and risk limits pertaining to market and liquidity risk management activities. ALCO meets regularly to discuss and review market and liquidity risk management strategies and consists of executive and senior management from various areas of the Corporation, including treasury, finance, economics, lending, deposit gathering and risk management. Corporate Treasury mitigates market and liquidity risk under the direction of ALCO through the actions it takes to manage the Corporation's market, liquidity and capital positions.

Table of Contents
In addition to assessing liquidity risk on a consolidated basis, Corporate Treasury also monitors the parent company's liquidity and has established limits for the minimum number of months into the future in which the parent company can meet existing and forecasted obligations without the support of additional dividends from subsidiaries. ALCO's liquidity policy requires the parent company to maintain sufficient liquidity to meet expected capital and debt obligations with a target of 24 months but no less than 18 months.
Corporate Treasury and the Enterprise Risk Division support ALCO in measuring, monitoring and managing interest rate risk as well as all other market risks. Key activities encompass: (i) providing information and analyses of the Corporation's balance sheet structure and measurement of interest rate and all other market risks; (ii) monitoring and reporting of the Corporation's positions relative to established policy limits and guidelines; (iii) developing and presenting analyses and strategies to adjust risk positions; (iv) reviewing and presenting policies and authorizations for approval; and (v) monitoring of industry trends and analytical tools to be used in the management of interest rate and all other market and liquidity risks.
Interest Rate Risk
Net interest income is the primary source of revenue for the Corporation. Interest rate risk arises in the normal course of business due to differences in the repricing and cash flow characteristics of assets and liabilities, primarily through the Corporation's core business activities of extending loans and acquiring deposits. The Corporation's balance sheet is predominantly characterized by floating-rate loans funded by core deposits. Including the impact of interest rate swaps converting floating-rate loans to fixed, the Corporation's loan composition at June 30, 2021 was 57 percent 30-day LIBOR, 5 percent other LIBOR (primarily 60-and 90-day), 12 percent prime and 26 percent fixed rate. Additionally, 29 percent of loans had non-zero interest rate floors protecting against future rate declines. The composition of the loan portfolio creates sensitivity to interest rate movements due to the imbalance between the faster repricing of the floating-rate loan portfolio versus deposit products. In addition, the growth and/or contraction in the Corporation's loans and deposits may lead to changes in sensitivity to interest rate movements in the absence of mitigating actions. Examples of such actions are purchasing fixed-rate investment securities, which provide liquidity to the balance sheet and act to mitigate the inherent interest sensitivity, as well as hedging with interest rate swaps and options. Other mitigating factors include interest rate floors on a portion of the loan portfolio. The Corporation actively manages its exposure to interest rate risk with the principal objective of optimizing net interest income and the economic value of equity while operating within acceptable limits established for interest rate risk and maintaining adequate levels of funding and liquidity.
Since no single measurement system satisfies all management objectives, a combination of techniques is used to manage interest rate risk. These techniques examine the impact of interest rate risk on net interest income and the economic value of equity under a variety of alternative scenarios, including changes in the level, slope and shape of the yield curve utilizing multiple simulation analyses. Simulation analyses produce only estimates of net interest income as the assumptions used are inherently uncertain. Actual results may differ from simulated results due to many factors, including, but not limited to, the timing, magnitude and frequency of changes in interest rates, market conditions, regulatory impacts and management strategies.
Sensitivity of Net Interest Income to Changes in Interest Rates
The analysis of the impact of changes in interest rates on net interest income under various interest rate scenarios is management's principal risk management technique. Management models a base-case net interest income under an unchanged interest rate environment. Existing derivative instruments entered into for risk management purposes as of the balance sheet dates are included in the analysis, but no additional hedging is forecasted. At June 30, 2021, these derivative instruments comprise interest rate swaps that convert $2.7 billion of fixed-rate medium- and long-term debt to variable rates through fair value hedges and convert $5.3 billion of variable-rate loans to fixed rates through cash flow hedges. Additionally, included in this analysis are $14.5 billion of loans that were subject to an average interest rate floor of 0.8 percent at June 30, 2021. This base-case net interest income is then compared against interest rate scenarios in which short-term rates rise or decline 100 basis points (with a floor of zero percent) in a linear, non-parallel fashion from the base case over 12 months, resulting in an average change of 50 basis points over the period while long-term rates increase or decrease to a lesser degree.
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 which are in line with historical patterns. However, in this low rate environment, depositors have maintained a higher level of liquidity and their historical behavior may be less indicative of future trends. As a result, the rising rate scenario reflects a greater decrease in deposits than 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, 2021 and December 31, 2020, 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 interest rates remained steady from December 31, 2020 to June 30, 2021 due to increased securities portfolio balances and growth of loan floors, partially offset by higher non-maturity deposit balances as well as limited remaining downward movement in rates before hitting zero percent floors. Sensitivity to rising interest rates increased slightly due to growth of non-maturity deposits, partially offset by an increase in investment securities.
Sensitivity of Economic Value of Equity to Changes in Interest Rates
In addition to the simulation analysis on net interest income, an economic value of equity analysis provides an alternative view of the interest rate risk position. The economic value of equity is the difference between the estimate of the economic value of the Corporation's financial assets, liabilities and off-balance sheet instruments, derived through discounting cash flows based on actual rates at the end of the period, and the estimated economic value after applying the estimated impact of rate movements. The Corporation primarily monitors the percentage change on the base-case economic value of equity. The economic value of equity analysis is based on an immediate parallel 100 basis point shock with a floor of zero percent.
The table below, as of June 30, 2021 and December 31, 2020, displays the estimated impact on the economic value of equity from the interest rate scenario described above.

Declining to zero percent(418)(3)Declining to zero percent(551)(6)
The sensitivity of the economic value of equity to rising rates decreased from December 31, 2020 to June 30, 2021 due primarily to duration extension and balance growth in the securities portfolio. Sensitivity to declining rates decreased due to changes in the securities portfolio and is limited by the assumption of a zero percent rate floor.
LIBOR Transition
On July 27, 2017, the United Kingdom’s Financial Conduct Authority (FCA), which regulates LIBOR, publicly announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. Effective March 2021, the FCA confirmed that certain LIBOR tenors will no longer be supported after December 31, 2021 and that the remaining tenors, including those most commonly used by the Corporation, will cease to be supported after June 30, 2023. 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. As of July 1, 2021, the Corporation was operationally ready to issue new Secured Overnight Financing Rate (SOFR)-based cash and derivative products. The Corporation is prepared for the cessation of the LIBOR tenors as announced by the FCA and will cease originating LIBOR-based products in the fourth quarter of 2021. Communications and learning activities to support customers and colleagues are ongoing. The Corporation’s enterprise transition milestones are closely aligned with recommendations from the Alternative Reference Rates Committee for both best practices and recommended objectives. The Corporation will continue to align with industry and regulatory guidelines regarding the cessation of LIBOR as well as monitor market developments for transitioning to alternative reference rates. For a discussion of the various risks facing the Corporation in relation to the transition away from LIBOR, see the market risk discussion within “Item 1A. Risk Factors” beginning on page 13 of the Corporation's Annual Report on Form 10-K for the year ended December 31, 2020.
Wholesale Funding
The Corporation may access the purchased funds market when necessary, which includes a variety of funding sources. Capacity for incremental purchased funds at June 30, 2021 included short-term FHLB advances, the ability to purchase federal funds, sell securities under agreements to repurchase as well as issue deposits through brokers. Purchased funds decreased to $23 million at June 30, 2021 compared to $66 million at December 31, 2020.

At June 30, 2021, the Bank had pledged loans totaling $19.8 billion which provided up to $15.8 billion of available collateralized borrowing with the Federal Reserve Bank (FRB).
The Bank is a member of the FHLB of Dallas, Texas, which provides short- and long-term funding to its members through advances collateralized by real estate-related assets. Actual borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At June 30, 2021, $18.5 billion of real estate-related loans and $3.2 billion of investment securities were pledged to the FHLB as collateral for potential future borrowings. The Corporation had capacity for potential future borrowings of approximately $11.9 billion.
In April 2021, the Bank terminated a $15.0 billion note program, under which the Bank had the ability to issue up to $13.5 billion of debt at the time of termination. Outstanding notes issued under the program were unaffected by the termination.
The Corporation maintains a shelf registration statement with the Securities and Exchange Commission from which it may issue debt and/or equity securities.
The ability of the Corporation and the Bank to raise funds at competitive rates may be impacted by rating agencies' views of the credit quality, liquidity, capital and earnings of the Corporation and the Bank. As of June 30, 2021, the three major rating agencies had assigned the ratings below to long-term senior unsecured obligations of the Corporation and the Bank. A security rating is not a recommendation to buy, sell, or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency. Each rating should be evaluated independently of any other rating.

The Corporation satisfies liquidity needs with either liquid assets or various funding sources. Liquid assets totaled $28.5 billion and $25.9 billion at June 30, 2021 and December 31, 2020, respectively. Liquid assets include cash and due from banks, federal funds sold, interest-bearing deposits with banks, other short-term investments and unencumbered investment securities.
The Corporation performs monthly liquidity stress testing to evaluate its ability to meet funding needs in hypothetical stressed environments. Such environments cover a series of broad events, distinguished in terms of duration and severity. The evaluation as of June 30, 2021 projected sufficient sources of liquidity were available under each series of events.
Total liquidity sources, comprised of liquid assets and remaining borrowing capacity with the FRB and the FHLB, totaled $56.2 billion at June 30, 2021. On a stand-alone basis, the Corporation had liquid assets of $1.0 billion on an unconsolidated basis at June 30, 2021.

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 2020 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, 2020, 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-39 through F-43 in the Corporation's 2020 Annual Report. As of the date of this report, there have been no significant changes to the Corporation's critical accounting policies or estimates, except for the MRVA methodology change described in Results of Operations and Note 1 to the consolidated financial statements.

SUPPLEMENTAL FINANCIAL DATA
The Corporation believes non-GAAP measures are meaningful because they reflect adjustments commonly made by management, investors, regulators and analysts to evaluate the adequacy of common equity and our performance trends. Tangible common equity is used by the Corporation to measure the quality of capital and the return relative to balance sheet risk.
Common equity tier 1 capital ratio removes preferred stock from the Tier 1 capital ratio as defined by and calculated in conformity with bank regulations. The tangible common equity ratio removes the effect of intangible assets from capital and total assets. Tangible common equity per share of common stock removes the effect of intangible assets from common shareholders' equity per share of common stock.
The following table provides a reconciliation of non-GAAP financial measures and regulatory ratios used in this financial review with financial measures defined by GAAP.
