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 nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. Certain items in prior periods were reclassified to conform to the current presentation. For further information, refer to the consolidated financial statements and footnotes thereto included in the Annual Report of Comerica Incorporated and Subsidiaries (the Corporation) on Form 10-K for the year ended December 31, 2018.

Leases

Effective January 1, 2019, the Corporation adopted the provisions of Accounting Standards Update (ASU) No. 2016-02, “Leases (Topic 842),” (ASU 2016-02), for all open leases with a term greater than one year as of the adoption date, using the modified retrospective approach. Prior comparable periods are presented in accordance with previous guidance under Accounting Standards Codification (ASC) 840, “Leases.”

Topic 842 requires the recognition of a lease liability, measured as the present value of unpaid lease payments for operating leases where the Corporation is the lessee, and a corresponding right-of-use (ROU) asset for the right to use the leased properties. The Corporation elected not to reassess whether contracts are or contain leases, lease classification or initial direct costs for existing leases, a set of practical expedients for transition provided by ASU 2016-12. Further, the Corporation elected the practical expedient to use hindsight in determining the lease term and assessing impairment. The election of the hindsight practical expedient resulted in longer lease terms for a limited number of strategic locations based on relevant factors as of the adoption date.

The impact at adoption was increases of $329 million and $343 million to total assets and liabilities, respectively, and a $14 million reduction to retained earnings. The increase in total assets was due to the recognition of ROU assets recorded in accrued income and other assets, and the increase in total liabilities was due to corresponding recognition of lease payment liabilities recorded in accrued expenses and other liabilities.

Operating lease liabilities reflect the Corporation’s obligation to make future lease payments, primarily for real estate locations. Lease terms typically comprise contractual terms but may include extension options reasonably certain of being exercised at lease inception for certain strategic locations such as regional headquarters. Payments are discounted using the rate the Corporation would pay to borrow amounts equal to the lease payments over the lease term (the Corporation’s incremental borrowing rate). The Corporation does not separate lease and non-lease components for contracts in which it is the lessee. ROU assets are measured based on lease liabilities adjusted for incentives as well as accrued and prepaid rent. Operating lease expense is recognized on a straight-line basis over the lease term, while variable lease payments are recognized as incurred. Common area maintenance and other executory costs are the main components of variable lease payments. Operating and variable lease expenses are recorded in net occupancy expense in the Consolidated Statements of Income.

The Corporation is the lessor in sales-type, direct finance and leveraged lease arrangements. Leases are recorded at the principal balance outstanding, net of unearned income and charge-offs. Interest income is recognized using the interest method. The impact of adopting Topic 842 for lessor accounting was not significant.

Pending Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," (ASU 2016-13), which addresses concerns regarding the perceived delay in recognition of credit losses under the existing incurred loss model. The amendment introduces a new, single model for recognizing credit losses on all financial instruments presented on a cost basis. Under the new model, entities must estimate current expected credit losses by considering all available relevant information, including historical and current conditions, as well as reasonable and supportable forecasts of future events. ASU 2016-13 also requires additional qualitative and quantitative disclosure to allow users to better understand the credit risk within the portfolio and the methodologies for determining the allowance for credit losses.

ASU 2016-13 is effective for the Corporation on January 1, 2020 and must generally be applied using the modified retrospective approach with a cumulative effect adjustment to retained earnings. In prior periods, the Corporation developed and completed internal validations of new credit estimation models. The Corporation has implemented new processes and controls for the execution of the new model and is in the process of testing them. The implementation team continues to challenge current model assumptions and outputs, refine the qualitative framework and finalize policies and disclosures. Additionally, parallel runs will continue in fourth quarter 2019 as more end-to-end processes, controls and policies are fina

lized.

Incorporating reasonable and supportable forecasts of economic conditions into the estimate of expected credit losses will require significant judgment, such as selecting economic variables and forecast scenarios as well as determining the appropriate length of the forecast horizon. Management will select economic variables it believes to be most relevant based on the composition of the loan portfolio and customer base, likely to include forecasted levels of employment, gross domestic product, corporate bond and treasury spreads, industrial production levels, consumer and commercial real estate price indices as well as housing statistics. Different economic forecasts ranging from more benign to more severe will be evaluated each reporting period to forecast losses over the contractual life of the loan portfolio. The Corporation anticipates using a two-year forecast horizon, which encompasses most of the remaining contractual life of its portfolio of commercial loans, reverting to its longer-term historical loss experience to estimate expected losses over any remaining contractual life.

The ultimate impact of ASU 2016-13 will depend on the composition of the portfolio as well as economic conditions and forecasts at the time of adoption. Based on current factors, the Corporation estimates overall allowance for credit losses to remain within 5 percent of current levels. The commercial portfolio, comprising the majority of the Corporation’s portfolio, consists of loans and lending arrangements with short contractual maturities that are expected to result in a reduction of up to 5 percent in the allowance for credit losses. The allowance for credit losses is expected to increase between 60 to 80 percent for the consumer portfolio given its longer contractual maturities.

ASU 2016-13 also requires expected credit losses on available-for-sale securities (AFS) debt securities be recorded as an allowance for credit losses. For certain types of debt securities, such as U.S. Treasuries and other securities with government guarantees, entities may expect zero credit losses. The Corporation believes the zero-loss expectation currently applies to all of its AFS securities.

ASU 2016-13 will be adopted in first quarter 2020.

NOTE 2 – FAIR VALUE MEASUREMENTS

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

Equity securities, investment securities available-for-sale, derivatives and deferred compensation plan assets and liabilities 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, 2018 for further information about the fair value hierarchy, descriptions of the valuation methodologies and key inputs used to measure financial assets and liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis.

Assets and Liabilities at Fair Value on a Nonrecurring Basis

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

The following table presents assets recorded at fair value on a nonrecurring basis at September 30, 2019 and December 31, 2018. No liabilities were recorded at fair value on a nonrecurring basis at September 30, 2019 and December 31, 2018.



(in millions)	Level 3

Loans:
Commercial	$	25
Total assets at fair value	$	25
December 31, 2018

Total assets at fair value	$	35

Level 3 assets recorded at fair value on a nonrecurring basis at September 30, 2019 and December 31, 2018 included loans 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:

At September 30, 2019, the Corporation had 178 residential mortgage-backed securities in an unrealized loss position with no credit impairment. The unrealized losses for these securities resulted from changes in market interest rates and liquidity, not changes in credit quality. The Corporation ultimately expects full collection of the carrying amount of these securities, does not intend to sell the securities in an unrealized loss position, and it is not more-likely-than-not that the Corporation will be required to sell the securities in an unrealized loss position prior to recovery of amortized cost. The Corporation does not consider these securities to be other-than-temporarily impaired at September 30, 2019.

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

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



(in millions)
September 30, 2019	Amortized Cost		Fair Value
Contractual maturity
Within one year	$	30	$	31
After one year through five years	2,818		2,874
After five years through ten years	1,127		1,134
After ten years	8,359		8,390
Total investment securities	$	12,334	$	12,429

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

At September 30, 2019, investment securities with a carrying value of $375 million were pledged where permitted or required by law to secure $270 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)

Special mention loans are accruing loans that have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. This category is generally consistent with the "special mention" category as defined by regulatory authorities.

(c)

Substandard loans are accruing loans that have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans also are distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. This category is generally consistent with the "substandard" category as defined by regulatory authorities.

(d)

Nonaccrual loans are loans for which the accrual of interest has been discontinued. For further information regarding nonaccrual loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies - on pages F-52 and F-53 in the Corporation's 2018 Annual Report. A significant majority of nonaccrual loans are generally consistent with the "substandard" category and the remainder are generally consistent with the "doubtful" category as defined by regulatory authorities.


(e)	Primarily loans to real estate developers.


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

Troubled Debt Restructurings

The following table details the recorded balance at September 30, 2019 and 2018 of loans considered to be troubled debt restructurings (TDRs) that were restructured during the three- and nine-month periods ended September 30, 2019 and 2018, by type of modification. In cases of loans with more than one type of modification, the loans were categorized based on the most significant modification.

The Corporation charges interest on principal balances outstanding during deferral periods. Additionally, none of the modifications involved forgiveness of principal.

At September 30, 2019 and December 31, 2018, commitments to lend additional funds to borrowers whose terms have been modified in TDRs totaled $2 million and $20 million, respectively. On an ongoing basis, the Corporation monitors the performance of modified loans to their restructured terms. The allowance for loan losses continues to be reassessed on the basis of an individual evaluation of the loan.

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

During the twelve-month periods ended September 30, 2019 and 2018, loans with a carrying value of $1 million and $3 million, respectively, were modified by interest rate reduction (reduced-rate loans).

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. Subsequent defaults of principal deferrals totaled $17 million in the three- and nine-month periods ended September 30, 2019 and none in the comparable periods in 2018. There were no subsequent defaults of interest rate reductions during either the three- and nine-month periods ended September 30, 2019 and 2018.

NOTE 5 - DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS

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

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

Credit risk is the possible loss that may occur in the event of nonperformance by the counterparty to a financial instrument. The Corporation attempts to minimize credit risk arising from customer-initiated derivatives by evaluating the creditworthiness of each customer, adhering to the same credit approval process used for traditional lending activities and obtaining collateral as deemed necessary. Derivatives with dealer counterparties are either cleared through a clearinghouse or settled directly with a single counterparty. For derivatives settled directly with dealer counterparties, the Corporation utilizes counterparty risk limits and monitoring procedures as well as master netting arrangements and bilateral collateral agreements to facilitate the management of credit risk. Master netting arrangements effectively reduce credit risk by permitting settlement of positive and negative positions and offset cash collateral held with the same counterparty on a net basis. Bilateral collateral agreements require daily exchange of cash or highly rated securities issued by the U.S. Treasury or other U.S. government entities to collateralize amounts due to either party. At September 30, 2019, counterparties with bilateral collateral agreements pledged $1 million of marketable investment securities and deposited $102 million of cash with the Corporation to secure the fair value of contracts in an unrealized gain position, and the Corporation had pledged $27 million of marketable investment securities and posted $13 million of cash as

collateral for contracts in an unrealized loss position. For those counterparties not covered under bilateral collateral agreements, collateral is obtained, if deemed necessary, based on the results of management’s credit evaluation of the counterparty. Collateral varies, but may include cash, investment securities, accounts receivable, equipment or real estate. Included in the fair value of derivative instruments are credit valuation adjustments reflecting counterparty credit risk. These adjustments are determined by applying a credit spread for the counterparty or the Corporation, as appropriate, to the total expected exposure of the derivative. There were no derivative instruments with credit-risk-related contingent features that were in a liability position at September 30, 2019.

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.

(a)	Included $189 million and $49 million of cumulative hedging adjustments to fair value hedges at September 30, 2019 and December 31, 2018, respectively, which included $7 million and $8 million, respectively, of hedging adjustment on a discontinued hedging relationship.


(b)	Variable rates paid on receive fixed swaps designated as fair value and cash flow hedges are based on one- and six-month LIBOR rates in effect at September 30, 2019 and December 31, 2018.

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

Customer-Initiated and Other

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

For customer-initiated foreign exchange contracts where offsetting positions have not been taken, the Corporation manages the remaining inherent market risk through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and reviewed quarterly. For those customer-initiated derivative contracts which were not offset or where the Corporation holds a position within the limits described above, the Corporation recognized no net gains or losses in other noninterest income in the Consolidated Statements of Comprehensive Income for both the three- and nine-month periods ended September 30, 2019 and 2018.

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

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)	September 30, 2019		December 31, 2018
Unused commitments to extend credit:
Commercial and other	$	23,280	$	24,266
Bankcard, revolving check credit and home equity loan commitments	3,156		3,001
Total unused commitments to extend credit	$	26,436	$	27,267
Standby letters of credit	$	3,281	$	3,244
Commercial letters of credit	17		39

The Corporation maintains an allowance to cover probable 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 $29 million and $30 million at September 30, 2019 and December 31, 2018, 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 $23 million at September 30, 2019 and $24 million at December 31, 2018 for probable 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. These risk participations covered $164 million and $136 million, respectively, of the $3.3 billion standby and commercial letters of credit outstanding at September 30, 2019 and December 31, 2018.

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 $33 million at September 30, 2019, including $27 million in deferred fees and $6 million in the allowance for credit losses on lending-related commitments. At December 31, 2018, the comparable amounts were $34 million, $28 million and $6 million, respectively.

The following table presents a summary of criticized standby and commercial letters of credit at September 30, 2019 and December 31, 2018. 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 agreement 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 had it entered into the derivative instruments directly with the borrower. The notional amount of such credit risk participation agreement reflects the pro-rata share of the derivative instrument, consistent with its share of the related participated loan. As of September 30, 2019 and December 31, 2018, the total notional amount of the credit risk participation agreements was approximately $744 million and $703 million, respectively, and the fair value was insignificant for both periods. The maximum estimated exposure to these agreements, as measured by projecting a maximum value of the guaranteed derivative instruments, assuming 100 percent default by all obligors on the maximum values, was $26 million and $7 million at September 30, 2019 and December 31, 2018, 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 September 30, 2019, the weighted average remaining maturity of outstanding credit risk participation agreements was 3.4 years.

NOTE 6 - VARIABLE INTEREST ENTITIES (VIEs)

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

The Corporation holds ownership interests in funds in the form of limited partnerships or limited liability companies (LLCs) investing in affordable housing projects that qualify for the low-income housing tax credit (LIHTC). The Corporation also directly invests in limited partnerships and LLCs that 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 September 30, 2019 was limited to $446 million and $6 million, respectively.

Investment balances, including all legally binding commitments to fund future investments, are included in accrued income and other assets on the Consolidated Balance Sheets. A liability is recognized in accrued expenses and other liabilities on the Consolidated Balance Sheets for all legally binding unfunded commitments to fund tax credit entities ($173 million at September 30, 2019). 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 nine months ended September 30, 2019 and 2018.

(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 rate on the FHLB advances resets between four and eight weeks, based on the FHLB auction rate. At September 30, 2019, the weighted-average rate on the FHLB advances was 2.21%. Each note may be prepaid in full, without penalty, at each scheduled reset date. Borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. At September 30, 2019, $17.2 billion of real estate-related loans were pledged to the FHLB as collateral for current and potential future borrowings of approximately $5.1 billion.

NOTE 11 - INCOME TAXES AND TAX-RELATED ITEMS

At September 30, 2019, net unrecognized tax benefits were $16 million, compared to $14 million at December 31, 2018. The Corporation anticipates it is reasonably possible settlements with tax authorities will result in a $1 million decrease in net unrecognized tax benefits within the next twelve months. The liability for tax-related interest and penalties included in accrued expenses and other liabilities was $8 million and $7 million on September 30, 2019 and December 31, 2018, respectively.

Net deferred tax assets were $92 million at September 30, 2019, compared to $166 million at December 31, 2018. The $74 million decrease in net deferred tax assets resulted primarily from a decrease in deferred tax assets, due to a decrease in unrealized losses on investment securities, and an increase in deferred tax liabilities arising from cash flow hedges used to manage interest rate risk. Included in deferred tax assets at both September 30, 2019 and December 31, 2018 were $4 million of state net operating loss carryforwards, which expire between 2019 and 2028. The Corporation believes 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 September 30, 2019 and December 31, 2018.

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

NOTE 12 - CONTINGENT LIABILITIES

Legal Proceedings

As previously reported in the Corporation's Form 10-K for the year ended December 31, 2018 and Forms 10-Q for the periods ended March 31, 2019 and June 30, 2019, the Bank was named in November 2011 as a third-party defendant in Butte Local Development v. Masters Group v. Comerica Bank (the case), for lender liability. The case was tried in January 2014, in the Montana Second District Judicial Court for Silver Bow County in Butte, Montana. On January 17, 2014, a jury awarded Masters $52 million against the Bank. On July 1, 2015, after an appeal filed by the Corporation, the Montana Supreme Court reversed the judgment against the Corporation and remanded the case for a new trial with instructions that Michigan contract law should apply and dismissing all other claims. The case was retried in the same district court, without a jury, in January 2017, and the Corporation awaits a ruling. Management believes current reserves related to this case are adequate in the event of a negative outcome.

The Corporation and certain of its subsidiaries are subject to various other pending or threatened legal proceedings arising out of the normal course of business or operations. The Corporation believes it has meritorious defenses to the claims asserted against it in its other currently outstanding legal proceedings and, with respect to such legal proceedings, intends to continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best interests of the

Corporation and its shareholders. Settlement may result from the Corporation's determination that it may be more prudent financially to settle, rather than litigate, and should not be regarded as an admission of liability. On at least a quarterly basis, the Corporation assesses its potential liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information available. On a case-by-case basis, reserves are established for those legal claims for which it is probable that a loss will be incurred either as a result of a settlement or judgment, and the amount of such loss can be reasonably estimated. The actual costs of resolving these claims may be substantially higher or lower than the amounts reserved. Based on current knowledge, and after consultation with legal counsel, management believes current reserves are adequate, and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the Corporation’s consolidated financial condition, results of operations or cash flows. Legal fees of $5 million and $4 million were included in other noninterest expenses for the three-month periods ended September 30, 2019 and 2018, respectively, and $10 million and $11 million for the nine-month periods ended September 30, 2019 and 2018, respectively.

For matters where a loss is not probable, the Corporation has not established legal reserves. The Corporation believes the estimate of the aggregate range of reasonably possible losses, in excess of reserves established, for all legal proceedings in which it is involved is from zero to approximately $35 million at September 30, 2019. This estimated aggregate range of reasonably possible losses is based upon currently available information for those proceedings in which the Corporation is involved, taking into account the Corporation’s best estimate of such losses for those cases for which such estimate can be made. For certain cases, the Corporation does not believe an estimate can currently be made. The Corporation’s estimate involves significant judgment, given the varying stages of the proceedings (including the fact many are currently in preliminary stages), the existence in certain proceedings of multiple defendants (including the Corporation) whose share of liability has yet to be determined, the numerous yet-unresolved issues in many of the proceedings (including issues regarding class certification and the scope of many of the claims) and the attendant uncertainty of the various potential outcomes of such proceedings. Accordingly, the Corporation’s estimate will change from time to time, and actual losses may be more or less than the current estimate.

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

For information regarding income tax contingencies, refer to Note 11.

NOTE 13 - BUSINESS SEGMENT INFORMATION

The Corporation has strategically aligned its operations into three major business segments: the Business Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. 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 September 30, 2019.

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

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

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

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

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

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

For further information on the methodologies which form the basis for these results refer to Note 23 to the consolidated financial statements in the Corporation's 2018 Annual Report.

RESULTS OF OPERATIONS

Net income for the three months ended September 30, 2019 was $292 million, a decrease of $26 million compared to $318 million for the three months ended September 30, 2018. The decrease in net income reflected an increase in the provision for credit losses, a significant decline in discrete tax benefits and lower net interest income, partially offset by a securities repositioning loss and restructuring charges in third quarter 2018. For the nine months ended September 30, 2019, net income was $929 million, an increase of $4 million compared to $925 million for the nine months ended September 30, 2018. The increase in net income reflected increases in net interest income and noninterest income, and lower expenses in part due to restructuring charges in 2018, partially offset by an increase in the provision for credit losses and a significant decline in discrete tax benefits.

Net income per diluted common share was $1.96 and $1.86 for the three months ended September 30, 2019 and 2018, respectively, an increase of 10 cents per diluted share. For the nine months ended September 30, 2019, net income per diluted common share was $6.02, an increase of 70 cents per diluted share compared to $5.32 for the nine months ended September 30, 2018. Net income per diluted share benefited from the decrease in shares outstanding due to repurchases in 2019.

The following table lists certain items impacting net income and earnings per share for the three- and nine-month periods ended September 30, 2019 and 2018.

(a)	Losses incurred on the sale of treasury securities that were replaced by higher-yielding securities.


(b)	Primarily tax benefits from adjustments to state tax filings in the third quarter 2019 and tax capitalization and recovery positions on fixed assets and software in the third quarter 2018, as well as from employee stock transactions.

Fourth Quarter 2019 Outlook

For the fourth quarter 2019 compared to third quarter 2019, management expects the following:


•	Average loans stable, reflecting growth in several lines of business, including a seasonal increase in National Dealer Services, offset by a decrease in Mortgage Banker Finance due to seasonality and lower refinancing activity.


•	Average deposits stable with continued focus on attracting and retaining relationship-based deposits.


•	Decline in net interest income due to the net impact of lower interest rates of approximately $40 million to $45 million (includes a 25 basis point reduction in the federal funds rate announced on October 30, 2019 with no further reductions included), as well as lower interest recoveries and loan fees from elevated third quarter levels.


•	Provision for credit losses of $25 million to $45 million and net charge-offs to remain low, with continued solid credit quality.


•	Noninterest income relatively stable, excluding the impact of deferred compensation asset returns, with higher syndication fees and fiduciary income in third quarter 2019 that are unlikely to repeat.


•	Noninterest expenses modestly higher, reflecting higher outside processing expenses, technology expenditures as well as seasonal and inflationary pressures.


•	Income tax expense to be approximately 23 percent of pre-tax income.


•	Common equity Tier 1 capital ratio target of approximately 10 percent with continued active capital management.

Full-Year 2019 Outlook Update

Consistent with the fourth quarter outlook, management now expects the following for full-year 2019 compared to full-year 2018:


•	Growth in average loans of 4 percent.


•	Decline in average deposits of 1 to 2 percent.


•	Net interest income stable to 1 percent lower (includes the 25 basis point reduction in the federal funds rate announced on October 30, 2019 with no further reductions included).


•	Provision for credit losses of 15 to 20 basis points of total loans.


•	Growth in noninterest income of greater than 2 percent.


•	Stable noninterest expenses excluding 2018 restructuring charges of $53 million.

Net interest income was $586 million for the third quarter 2019, a decrease of $13 million compared to $599 million for the third quarter 2018. The decrease in net interest income primarily reflected higher deposit costs, the impact of lower Federal Reserve Bank (FRB) deposits (included in interest-bearing deposits with banks) and higher balances in interest-bearing sources, partially offset by higher loan balances and the impact of higher short-term rates on loans and securities. Net interest margin for the three months ended September 30, 2019 decreased 7 basis points to 3.52 percent, from 3.59 percent for the comparable period in 2018, primarily reflecting higher deposit costs and higher balances in interest-bearing sources, partially offset by higher loan balances, the impact of higher short-term rates on loans and securities, as well as a decrease in lower-yielding FRB deposits balances.

Provision for Credit Losses

The provision for credit losses was $35 million for the three months ended September 30, 2019, compared to no provision for the three months ended September 30, 2018. The provision for credit losses includes both the provision for loan losses and the provision for credit losses on lending-related commitments. The provision for loan losses is recorded to maintain the allowance for loan losses at the level deemed appropriate by the Corporation to cover probable credit losses inherent in the portfolio and includes qualitative adjustments for factors that have not been fully accounted for in the quantitative reserve calculations. The provision for credit losses on lending-related commitments is recorded to maintain the allowance for credit losses on lending-related commitments at the level deemed appropriate by the Corporation to cover probable credit losses inherent in lending-related commitments.

The provision for loan losses increased $36 million to $37 million for the three months ended September 30, 2019, compared to $1 million for the three months ended September 30, 2018. The increase in the provision resulted primarily from loan growth and increased Energy reserves. Net loan charge-offs were $42 million for the three months ended September 30, 2019 compared to $15 million for the three months ended September 30, 2018. The increase in net charge-offs was driven by a $34 million increase in Energy, primarily due to continued declines in valuation of select energy assets.

The provision for credit losses on lending-related commitments decreased $1 million to a $2 million benefit for the three months ended September 30, 2019, compared to a benefit of $1 million for the three months ended September 30, 2018. There were no lending-related commitment charge-offs in the three-month periods ended September 30, 2019 and 2018.

An analysis of the allowance for credit losses and nonperforming assets is presented under the "Credit Risk" subheading in the "Risk Management" section of this financial review.

Noninterest expenses decreased $17 million to $435 million. Excluding $12 million of restructuring charges in 2018, noninterest expenses decreased $5 million, primarily reflecting a decrease in FDIC insurance expense due to the discontinuance of FDIC surcharges.

Provision for Income Taxes

The provision for income taxes increased $17 million to $80 million. The increase was primarily due to an $18 million decrease in certain discrete tax benefits. Discrete tax benefits were $5 million in third quarter 2019, primarily resulting from state deferred tax adjustments, compared to $23 million in third quarter 2018, resulting from a review of certain tax capitalization and recovery positions.

Net interest income was $1.8 billion for the nine months ended September 30, 2019, an increase of $57 million compared to $1.7 billion for the nine months ended September 30, 2018. The increase in net interest income primarily reflected a net benefit from higher rates and an increase in loan balances, partially offset by lower balances deposited with the FRB (included in interest-bearing deposits with banks) as well as higher balances in interest-bearing sources of funds. The net interest margin for the nine months ended September 30, 2019 increased 11 basis points to 3.65 percent from 3.54 percent for the comparable period in 2018, primarily reflecting the net benefit from higher rates, higher loan balances and a decrease in lower-yielding FRB deposit balances, partially offset by higher balances from interest-bearing sources.

Provision for Credit Losses

The provision for credit losses, which includes both the provision for loan losses and the provision for credit losses on lending-related commitments, was $66 million for the nine months ended September 30, 2019, compared to a benefit of $17 million for the nine months ended September 30, 2018. The provision for loan losses was $67 million for the nine months ended September 30, 2019, compared to a benefit of $8 million for the nine months ended September 30, 2018. The increase in the provision primarily reflected an increase in Energy reserves. Net loan charge-offs increased $46 million to $86 million for the nine months ended September 30, 2019, compared to $40 million for the nine months ended September 30, 2018. The increase in net charge-offs was driven by a $61 million increase in Energy.

The provision for credit losses on lending-related commitments increased $8 million to a $1 million benefit for the nine months ended September 30, 2019 compared to a benefit of $9 million for the nine months ended September 30, 2018. The increase primarily reflected the impact of a larger benefit in 2018 driven by a decrease in Energy commitments. There were no lending-related commitment charge-offs for the nine months ended September 30, 2019 and 2018.

STRATEGIC LINES OF BUSINESS

The Corporation has strategically aligned its operations into three major business segments: the Business Bank, the Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. The Other category includes items not directly associated with these business segments or the Finance segment. The performance of the business segments is not comparable with the Corporation's consolidated results and is not necessarily comparable with similar information for any other financial institution. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. Market segment results are also provided for the Corporation's three primary geographic markets: Michigan, California and Texas. In addition to the three primary geographic markets, Other Markets is also reported as a market segment. Note 13 to the consolidated financial statements describes the business activities of each business segment and presents financial results of these business and market segments for the three- and nine-month periods ended September 30, 2019 and 2018.

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 23 to the consolidated financial statements in the Corporation's 2018 Annual Report describes the Corporation's segment reporting methodology.

Net interest income for each segment reflects the interest income generated by earning assets less interest expense on interest-bearing liabilities plus the net impact from associated internal funds transfer pricing (FTP). The FTP methodology allocates credits to each business segment for deposits and other funds provided as well as charges for loans and other assets being funded. FTP crediting rates for deposits and other funds provided reflect the long-term value of deposits and other funding sources based on their implied maturities. FTP charge rates for funding loans and other assets reflect a matched cost of funds based on the pricing and duration characteristics of the assets. Therefore, net interest income for each segment primarily reflects the volume and associated FTP impacts of loan and deposit levels. As overall market rates increased, business segments, particularly those focused on generating deposits, benefited from higher FTP crediting rates on deposits in the nine months ended September 30, 2019 compared to the same period in the prior year. Similarly, FTP charges for funding loans increased in the nine months ended September 30, 2019, compared to the same period in the prior year. Effective January 1, 2019, the Corporation prospectively discontinued allocating an additional FTP charge for the cost of maintaining liquid assets to support potential draws on unfunded loan commitments.

The following sections present a summary of the performance of each of the Corporation's business and market segments for the nine months ended September 30, 2019 compared to the same period in the prior year.

The Business Bank's net income increased $5 million to $760 million. Average loans increased $1.9 billion and average deposits decreased $1.6 billion. Net interest income increased $52 million to $1.3 billion. An increase in loan income of $196 million was partially offset by increases of $96 million in allocated net FTP charges and $48 million in deposit costs. The provision for credit losses increased $94 million to $85 million from a benefit of $9 million, primarily reflecting loan growth and an increase in Energy reserves. Net credit-related charge-offs increased $50 million to $90 million, primarily reflecting an increase in Energy. Noninterest income increased $9 million, primarily reflecting increases of $13 million in card fees and $4 million in commercial lending fees, partially offset by decreases of $4 million each in service charges on deposit accounts and investment banking fees. Excluding restructuring charges of $23 million in the nine months ended September 30, 2018, noninterest expenses decreased $20 million, primarily reflecting decreases of $13 million each in corporate overhead and FDIC insurance expense, partially offset by an increase of $4 million in outside processing fee expense and smaller increases in other categories.

FINANCIAL CONDITION

Third Quarter 2019 Compared to Fourth Quarter 2018

Period-End Balances

Total assets increased $2.0 billion to $72.8 billion, driven by increases of $1.3 billion in loans and $739 million in other assets. Total liabilities increased $2.3 billion to $65.6 billion, primarily reflecting increases of $2.8 billion in interest-bearing deposits and $848 million in medium- and long-term debt, partially offset by a $1.6 billion decrease in noninterest-bearing deposits. The increase in medium- and long-term debt reflected issuances of $350 million in long-term notes in February 2019, $500 million in medium-term notes in July 2019 and $200 million in long-term notes in August 2019, partially offset by the maturity of $350 million of medium-term notes in May 2019. The decrease in noninterest-bearing deposits included a $1.2 billion decrease due to the timing of deposits funding a government card program which typically fund on the first day of each month. The January 2019 deposit was received on December 31, 2018 due to the New Year's holiday. Total shareholders' equity decreased $307 million to $7.2 billion. The decrease in shareholders' equity reflected the impact of $1.5 billion returned to shareholders through dividends and share repurchases, partially offset by total comprehensive income of $1.2 billion in the nine months ended September 30, 2019.

The increase in loans was largely attributed to increases in Mortgage Banker Finance, Energy and general Middle Market.

Total liabilities increased $1.2 billion, primarily due to increases of $680 million in medium- and long-term debt and $308 million in accrued expenses and other liabilities. The increase in medium- and long-term debt was due to the same reasons as the increase in period-end balances discussed above. The increase in accrued expenses and other liabilities is largely due to the recognition of a lease liability related to the adoption of ASC 842.

Total equity decreased $265 million to $7.3 billion, for the same reasons as the decrease in period-end balances discussed above.

RISK MANAGEMENT

The following updated information should be read in conjunction with the "Risk Management" section on pages F-21 through F-34 in the Corporation's 2018 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. The allowance for loan losses represents management's assessment of probable, estimable losses inherent in the Corporation's loan portfolio. The allowance for credit losses on lending-related commitments, included in accrued expenses and other liabilities on the Consolidated Balance Sheets, provides for probable losses inherent in lending-related commitments, including unused commitments to extend credit and standby letters of credit.

The allowance for loan losses was $652 million at September 30, 2019, compared to $671 million at December 31, 2018, a decrease of $19 million, or 3 percent. As a percentage of total loans, the allowance for loan losses was 1.27 percent at September 30, 2019, compared to 1.34 percent at December 31, 2018. The decrease in the allowance for loan losses reflected sustained solid credit quality of the portfolio as a whole and included increases in Energy reserves. The sustained solid credit quality was reflected by nonperforming loans as a percentage of total loans of 0.44 percent at September 30, 2019, compared to 0.46 percent at December 31, 2018, and an allowance coverage of 2.9 times nonperforming assets at both September 30, 2019 and December 31, 2018.

Table of Contents

The allowance for credit losses on lending-related commitments includes specific allowances, based on individual evaluations of certain letters of credit in a manner consistent with business loans, and allowances based on the pool of the remaining letters of credit and all unused commitments to extend credit within each internal risk rating. The allowance for credit losses on lending-related commitments was $29 million and $30 million at September 30, 2019 and December 31, 2018, respectively.

For additional information regarding the allowance for credit losses, refer to page F-35 in the "Critical Accounting Policies" section and pages F-51 through F-52 in Note 1 to the consolidated financial statements of the Corporation's 2018 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 property. TDRs include performing and nonperforming loans. Nonperforming TDRs are either on nonaccrual or reduced-rate status.

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

(a)	Primarily loans to real estate developers.


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

The Corporation limits risk inherent in its commercial real estate lending activities by monitoring borrowers directly involved in the commercial real estate markets and adhering to conservative policies on loan-to-value ratios for such loans. Commercial real estate loans, consisting of real estate construction and commercial mortgage loans, totaled $12.6 billion at September 30, 2019, of which $4.9 billion, or 39 percent, were to borrowers in the Commercial Real Estate business line, which includes loans to real estate developers, an increase of $428 million compared to December 31, 2018. The remaining $7.7 billion, or 61 percent, of commercial real estate loans in other business lines consisted primarily of owner-occupied commercial mortgages, which bear credit characteristics similar to non-commercial real estate business loans.

The real estate construction loan portfolio primarily contains loans made to long-tenured customers with satisfactory completion experience. Criticized real estate construction loans in the Commercial Real Estate business line totaled $36 million and $23 million at September 30, 2019 and December 31, 2018, respectively. In other business lines, there were no criticized real estate construction loans at September 30, 2019, compared to $8 million at December 31, 2018. There were no charge-offs in either of the nine-month periods ended September 30, 2019 and 2018.

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 $56 million and $61 million at September 30, 2019 and December 31, 2018, respectively. In other business lines, $189 million and $206 million of commercial mortgage loans were criticized at September 30, 2019 and December 31, 2018, respectively. Commercial mortgage loan net recoveries were $2 million and $1 million for the nine months ended September 30, 2019 and 2018, respectively.

Residential Real Estate Lending

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, totaled $3.6 billion, or 7 percent of total loans, at September 30, 2019. The following table summarizes the Corporation's residential mortgage and home equity loan portfolios by geographic market.



	September 30, 2019								December 31, 2018

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

Residential mortgages totaled $1.9 billion at September 30, 2019, and were primarily larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.9 billion of residential mortgage loans outstanding, $36 million were on nonaccrual status at September 30, 2019. The home equity portfolio totaled $1.7 billion at September 30, 2019, of which $1.6 billion was outstanding under primarily variable-rate, interest-only home equity lines of credit, $97 million were in amortizing status and $25 million were closed-end home equity loans. Of the $1.7 billion of home equity loans outstanding, $17 million were on nonaccrual status at September 30, 2019. A majority of the home equity portfolio was secured by junior liens at September 30, 2019.

Energy Lending

Loans in the Corporation's Energy business line are included almost entirely in commercial loans in the Consolidated Balance Sheets. Customers in the Corporation's Energy line of business (approximately 150 relationships) are engaged in three segments of the oil and gas business: exploration and production (E&P), midstream and energy services. E&P generally includes such activities as searching for potential oil and gas fields, drilling exploratory wells and operating active wells. Commitments to E&P borrowers are generally subject to semi-annual borrowing base re-determinations based on a variety of factors including updated pricing (reflecting market and competitive conditions), energy reserve levels and the impact of hedging. The midstream sector is generally involved in the transportation, storage and marketing of crude and/or refined oil and gas products. The Corporation's energy services customers provide products and services primarily to the E&P segment.

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



	September 30, 2019										December 31, 2018
(dollar amounts in millions)	Outstandings				Nonaccrual			Criticized (a)			Outstandings				Nonaccrual			Criticized (a)

As a percentage of total Energy loans					3		%	9		%					2		%	9		%


(a)	Includes nonaccrual loans.

Loans in the Energy business line totaled $2.4 billion, or less than 5 percent of total loans, at September 30, 2019 and $2.2 billion at December 31, 2018, an increase of $259 million. Total exposure, including unused commitments to extend credit and letters of credit, was $4.7 billion and $4.5 billion at September 30, 2019 and December 31, 2018, respectively.

The Corporation's allowance methodology considers the various risk elements within the loan portfolio. When merited, the Corporation may incorporate a qualitative reserve component for Energy loans. Net credit-related charge-offs were $34 million and $67 million for the three- and nine-month periods ended September 30, 2019, respectively, compared to $3 million and $7 million for the comparable periods in 2018. Nonaccrual loans increased $26 million to $74 million at September 30, 2019. The increases in both net charge-offs and nonaccrual loans resulted from the impact of a decline in valuations of select liquidating assets related to Energy loans from illiquid capital markets in the industry.

Automotive Lending

Substantially all dealer loans are in the National Dealer Services business line. Loans in the National Dealer Services business line primarily include floor plan financing and other loans to automotive dealerships. Floor plan loans, included in commercial loans, totaled $4.1 billion at September 30, 2019, a decrease of $598 million compared to $4.7 billion at December 31, 2018. At both September 30, 2019 and December 31, 2018, other loans to automotive dealers in the National Dealer Services business line totaled $3.4 billion, including $2.1 billion and $2.0 billion of owner-occupied commercial real estate mortgage loans at September 30, 2019 and December 31, 2018, respectively. Automotive lending also includes loans to borrowers involved with automotive production, primarily Tier 1 and Tier 2 suppliers. Loans to borrowers involved with automotive production totaled $1.3 billion at both September 30, 2019 and December 31, 2018.

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. HR C&I loans were $2.5 billion at both September 30, 2019 and December 31, 2018. Criticized loans within the HR C&I loan portfolio were $133 million and $147 million at September 30, 2019 and December 31, 2018, respectively. Charge-offs of HR C&I loans totaled $1 million and $6 million for the three- and nine-month periods ended September 30, 2019, respectively, compared to $1 million and $14 million for the same periods in 2018.

For further discussion of credit risk, see the "Credit Risk" section of pages F-21 through F-29 in the Corporation's 2018 Annual Report.

Market and Liquidity Risk

Market risk represents the risk of loss due to adverse movements in market rates or prices, including interest rates, foreign exchange rates, commodity prices and equity prices. Liquidity risk represents the failure to meet financial obligations coming due resulting from an inability to liquidate assets or obtain adequate funding, and the inability to easily unwind or offset specific exposures without significant changes in pricing, due to inadequate market depth or market disruptions.

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

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

Corporate Treasury and the Enterprise Risk Division support ALCO in measuring, monitoring and managing interest rate risk as well as all other market risks. Key activities encompass: (i) providing information and analysis 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 September 30, 2019 was 62 percent 30-day LIBOR, 6 percent other LIBOR (primarily 60-

Table of Contents

day), 15 percent prime and 17 percent fixed rate. This creates sensitivity to interest rate movements due to the imbalance between the faster repricing of the floating-rate loan portfolio versus deposit products. In addition, the growth and/or contraction in the Corporation's loans and deposits may lead to changes in sensitivity to interest rate movements in the absence of mitigating actions. Examples of such actions are purchasing fixed-rate investment securities, which provide liquidity to the balance sheet and act to mitigate the inherent interest sensitivity, as well as hedging with interest rate swaps and options. 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 reporting date are included in the analysis, but no additional hedging is forecasted. At September 30, 2019, these derivative instruments comprise interest rate swaps that convert $3.3 billion of fixed-rate medium- and long-term debt to variable rates through fair value hedges and $3.8 billion of variable-rate loans to fixed rates through cash flow hedges. This base case net interest income is then compared against interest rate scenarios in which rates rise or decline 200 basis points in a linear, non-parallel fashion from the base case over 12 months, resulting in an average increase or decrease in short-term interest rates of 100 basis points over the period.

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

The table below, as of September 30, 2019 and December 31, 2018, 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.



	Estimated Annual Change
	September 30, 2019					December 31, 2018
(in millions)	Amount			%		Amount			%
Change in Interest Rates:
Rising 200 basis points	$	122		6	%	$	142		6	%
Declining 200 basis points	(264		)	(12	)	(313		)	(12	)

Sensitivity to rising and declining rates decreased from December 31, 2018 to September 30, 2019 due to the impact of swaps converting variable-rate loans to fixed rates and changes in balance sheet composition.

The ultimate impact of changes in rates depends in part on the pace at which deposits reprice (deposit beta). The scenarios shown above reflect management's expectation that deposit betas are likely to lag if interest rates decline, as they did at the recent cycle when rates began to rise. Varying the deposit beta assumption results in different estimated impacts to net interest income. For example, management estimates the annual impact to net interest income of a decline in short-term rates of 50 basis points over a 12-month period (25 basis-point shock) can range between a decrease of approximately $65 million (50 percent deposit beta) to $95 million (10 percent deposit beta) depending on the deposit beta assumption.

During October 2019, the Corporation added interest rate swaps that convert an additional $750 million of variable-rate loans to fixed rates through cash flow hedges. These additional hedges are not included in the sensitivity analysis discussed above.

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 200 basis point shock.

The table below, as of September 30, 2019 and December 31, 2018, displays the estimated impact on the economic value of equity from the interest rate scenario described above.



	September 30, 2019					December 31, 2018
(in millions)	Amount			%		Amount			%
Change in Interest Rates:
Rising 200 basis points	$	1,126		12	%	$	711		6	%
Declining 200 basis points	(2,058		)	(22	)	(2,769		)	(21	)

The sensitivity of the economic value of equity to rising rates increased and declining rates decreased from December 31, 2018 to September 30, 2019 due to the addition of swaps converting variable-rate loans to fixed rates, model updates to average deposit life assumptions and changes in balance sheet composition.

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 September 30, 2019 included short-term FHLB advances, the ability to purchase federal funds, sell securities under agreements to repurchase, as well as issue deposits through brokers. Other time deposits totaled $647 million, compared to none at December 31, 2018, reflecting the issuance of brokered deposits. At September 30, 2019, the Bank had pledged loans totaling $23.0 billion which provided for up to $18.6 billion of available collateralized borrowing with the 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 September 30, 2019, $17.2 billion of real estate-related loans were pledged to the FHLB as collateral for current and potential future borrowings. The Corporation had $3.8 billion of FHLB borrowings maturing between 2026 and 2028 and capacity for potential future borrowings of approximately $5.1 billion.

Additionally, as of September 30, 2019 the Bank had the ability to issue up to $13.5 billion of debt under an existing $15.0 billion note program which allows the issuance of debt with maturities between three months and 30 years. The Corporation also maintains a shelf registration statement with the Securities and Exchange Commission from which it may issue debt and/or equity securities.

The ability of the Corporation and the Bank to raise funds at competitive rates is impacted by rating agencies' views of the credit quality, liquidity, capital and earnings of the Corporation and the Bank. As of September 30, 2019, 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 $16.3 billion at both September 30, 2019 and December 31, 2018. 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 September 30, 2019 projected sufficient sources of liquidity were available under each series of events.

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 2018 Annual Report. These policies require numerous estimates and strategic or economic assumptions, which may prove inaccurate or subject to variations. Changes in underlying factors, assumptions or estimates could have a material impact on the Corporation’s future financial condition and results of operations. At December 31, 2018, 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-35 through F-37 in the Corporation's 2018 Annual Report. As of the date of this report, there have been no significant changes to the Corporation's critical accounting policies or estimates.

The Corporation performed the annual goodwill impairment test in third quarter 2019, resulting in the following updates to the critical accounting policy discussed on page F-36 of the Corporation's 2018 Annual Report.

Goodwill

Goodwill is initially recorded as the excess of the purchase price over the fair value of net assets acquired in a business combination and is subsequently evaluated at least annually for impairment. Goodwill impairment testing is performed at the reporting unit level, equivalent to a business segment or one level below. The Corporation has three reporting units: the Business Bank, the Retail Bank and Wealth Management. At September 30, 2019 and December 31, 2018, goodwill totaled $635 million, including $473 million allocated to the Business Bank, $101 million allocated to the Retail Bank and $61 million allocated to Wealth Management.

The annual test of goodwill impairment was performed as of the beginning of the third quarter of 2019. The Corporation first assessed qualitative factors to determine whether it was more likely than not that the fair value of any reporting unit was less than its carrying amount, including goodwill. Qualitative factors included economic conditions, industry and market considerations, cost factors, overall financial performance, regulatory developments and performance of the Corporation’s stock, among other events and circumstances. At the conclusion of the qualitative assessment in the third quarter 2019, the Corporation determined that it was more likely than not that the fair value of each reporting unit exceeded its carrying value.

Qualitative factors considered in the analysis of each reporting unit incorporated current economic and market conditions, including the recent Federal Reserve announcements and the impact of legislative and regulatory changes, to the extent known. However, further weakening in the economic environment, such as continued declines in interest rates, a decline in the performance of the reporting units or other factors could cause the fair value of one or more of the reporting units to fall below their carrying value, resulting in a goodwill impairment charge. Additionally, new legislative or regulatory changes not anticipated in management's expectations may cause the fair value of one or more of the reporting units to fall below the carrying value, resulting in a goodwill impairment charge. Any impairment charge would not affect the Corporation's regulatory capital ratios, tangible equity ratio or liquidity position.

SUPPLEMENTAL FINANCIAL DATA

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

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