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 three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. 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, 2013.

Recently Adopted Accounting Pronouncement

Effective January 1, 2014, the Corporation early adopted Accounting Standards Update (ASU) No. 2014-01, “Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects,” an amendment to GAAP which enables companies that invest in affordable housing projects that qualify for the low-income housing tax credit (LIHTC) to elect to use the proportional amortization method if certain conditions are met. Under the proportional amortization method, the initial investment cost of the project is amortized in proportion to the amount of tax credits and other benefits received, with the results of the investment presented on a net basis as a component of the provision for income taxes. Previously, LIHTC investments were accounted for under the cost or equity method, and the amortization was recorded as a reduction to other noninterest income, with the tax credits and other benefits received recorded as a component of the provision for income taxes. The Corporation believes the proportional amortization method better represents the economics of LIHTC investments and provides users with a better understanding of the returns from such investments than the cost or equity method.

The cumulative effect of the retrospective application of the change in amortization method was a $3 million decrease to both "accrued income and other assets" and "retained earnings" on the consolidated balance sheets as of January 1, 2013. The unaudited consolidated financial statements have been retrospectively adjusted to reflect the prior period effect of the adoption of the amendment, which resulted in a $13 million increase to both "other noninterest income" and "provision for income taxes" for the three months ended March 31, 2013. The adoption of ASU 2014-01 had no effect on net income or earnings per common share for any period presented.

See Note 6 to these unaudited consolidated financial statements for additional information regarding LIHTC and other tax credit investments.

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.

Fair value is an estimate of the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction (i.e., not a forced transaction, such as a liquidation or distressed sale) between market participants at the measurement date. However, the calculated fair value estimates in many instances cannot be substantiated by comparison to independent markets and, in many cases, may not be realizable in a current sale of the financial instrument.

Trading securities, investment securities available-for-sale, derivatives and deferred compensation plan 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.

The Corporation categorizes assets and liabilities recorded at fair value on a recurring or nonrecurring basis and the estimated fair value of financial instruments not recorded at fair value on a recurring basis into a three-level hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.



	Level 1		Valuation is based upon quoted prices for identical instruments traded in active markets.

	Level 2		Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

	Level 3		Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

The Corporation generally utilizes third-party pricing services to value Level 1 and Level 2 trading securities and investment securities available-for-sale, as well as certain derivatives designated as fair value hedges. Management reviews the methodologies and assumptions used by the third-party pricing services and evaluates the values provided, principally by comparison with other available market quotes for similar instruments and/or analysis based on internal models using available third-party market data. The Corporation may occasionally adjust certain values provided by the third-party pricing service when management believes, as the result of its review, that the adjusted price most appropriately reflects the fair value of the particular security.

Following are 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. The descriptions include an indication of the level of the fair value hierarchy in which the assets or liabilities are classified. Transfers of assets or liabilities between levels of the fair value hierarchy are recognized at the beginning of the reporting period, when applicable.

Cash and due from banks, federal funds sold and interest-bearing deposits with banks

Due to their short-term nature, the carrying amount of these instruments approximates the estimated fair value. As such, the Corporation classifies the estimated fair value of these instruments as Level 1.

Trading securities and associated deferred compensation plan liabilities

Trading securities include securities held for trading purposes as well as assets held related to employee deferred compensation plans. Trading securities and associated deferred compensation plan liabilities are recorded at fair value on a recurring basis and included in “other short-term investments” and “accrued expenses and other liabilities,” respectively, on the consolidated balance sheets. Level 1 trading securities include assets related to employee deferred compensation plans, which are invested in mutual funds, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and other securities traded on an active exchange, such as the New York Stock Exchange. Deferred compensation plan liabilities represent the fair value of the obligation to the employee, which corresponds to the fair value of the invested assets. Level 2 trading securities include municipal bonds and residential mortgage-backed securities issued by U.S. government-sponsored entities and corporate debt

securities. The methods used to value trading securities are the same as the methods used to value investment securities available-for-sale, discussed below.

Loans held-for-sale

Loans held-for-sale, included in “other short-term investments” on the consolidated balance sheets, are recorded at the lower of cost or fair value. Loans held-for-sale may be carried at fair value on a nonrecurring basis when fair value is less than cost. The fair value is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Corporation classifies both loans held-for-sale subjected to nonrecurring fair value adjustments and the estimated fair value of loans held-for sale as Level 2.

Investment securities available-for-sale

Investment securities available-for-sale are recorded at fair value on a recurring basis. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include residential mortgage-backed securities issued by U.S. government agencies and U.S. government-sponsored entities and corporate debt securities. The fair value of Level 2 securities was determined using quoted prices of securities with similar characteristics, or pricing models based on observable market data inputs, primarily interest rates, spreads and prepayment information.

Securities classified as Level 3 represent securities in less liquid markets requiring significant management assumptions when determining fair value. Auction-rate securities comprise Level 3 investment securities available-for-sale. Due to the lack of a robust secondary auction-rate securities market with active fair value indicators, fair value for all periods presented was determined using an income approach based on a discounted cash flow model. The discounted cash flow model utilizes two significant inputs: discount rate and workout period. The discount rate was calculated using credit spreads of the underlying collateral or similar securities plus a liquidity risk premium. The liquidity risk premium was derived from the rate at which various types of similar auction-rate securities had been redeemed or sold. The workout period was based on an assessment of publicly available information on efforts to re-establish functioning markets for these securities and the Corporation's own redemption experience. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. The Corporate Development Department, with appropriate oversight and approval provided by senior management, is responsible for determining the valuation methodology for auction-rate securities and for updating significant inputs based on changes to the factors discussed above. Valuation results, including an analysis of changes to the valuation methodology and significant inputs, are provided to senior management for review on a quarterly basis.

Loans

The Corporation does not record loans at fair value on a recurring basis. However, the Corporation may establish a specific allowance for an impaired loan based on the fair value of the underlying collateral. Such loan values are reported as nonrecurring fair value measurements. Collateral values supporting individually evaluated impaired loans are evaluated quarterly. When management determines that the fair value of the collateral requires additional adjustments, either as a result of non-current appraisal value or when there is no observable market price, the Corporation classifies the impaired loan as Level 3. The Special Assets Group is responsible for performing quarterly credit quality reviews for all impaired loans as part of the quarterly allowance for loan losses process overseen by the Chief Credit Officer, during which valuation adjustments to updated collateral values are determined.

The Corporation discloses fair value estimates for loans. The estimated fair value is determined based on characteristics such as loan category, repricing features and remaining maturity, and includes prepayment and credit loss estimates. For variable rate business loans that reprice frequently, the estimated fair value is based on carrying values adjusted for estimated credit losses inherent in the portfolio at the balance sheet date. For other business loans and retail loans, fair values are estimated using a discounted cash flow model that employs a discount rate that reflects the Corporation's current pricing for loans with similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable. The Corporation classifies the estimated fair value of loans held for investment as Level 3.

Customers’ liability on acceptances outstanding and acceptances outstanding

Customers' liability on acceptances outstanding is included in "accrued income and other assets" and acceptances outstanding are included in "accrued expenses and other liabilities" on the consolidated balance sheets. Due to their short-term nature, the carrying amount of these instruments approximates the estimated fair value. As such, the Corporation classifies the estimated fair value of these instruments as Level 1.

Derivative assets and derivative liabilities

Derivative instruments held or issued for risk management or customer-initiated activities are traded in over-the-counter markets where quoted market prices are not readily available. Fair value for over-the-counter derivative instruments is measured on a recurring basis using internally developed models that use primarily market observable inputs, such as yield curves and option volatilities. The Corporation manages credit risk on its derivative positions based on whether the derivatives are being settled through a clearinghouse or bilaterally with each counterparty. For derivative positions settled on a counterparty-by-counterparty basis, the Corporation calculates credit valuation adjustments, included in the fair value of these instruments, on the basis of its relationships at the counterparty portfolio/master netting agreement level. These credit valuation adjustments are determined by applying a credit spread for the counterparty or the Corporation, as appropriate, to the total expected exposure of the derivative after considering collateral and other master netting arrangements. These adjustments, which are considered Level 3 inputs, are based on estimates of current credit spreads to evaluate the likelihood of default. The Corporation assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Corporation classifies its over-the-counter derivative valuations in Level 2 of the fair value hierarchy. Examples of Level 2 derivative instruments are interest rate swaps and energy derivative and foreign exchange contracts.

Warrants which contain a net exercise provision or a non-contingent put right embedded in the warrant agreement are accounted for as derivatives and recorded at fair value on a recurring basis using a Black-Scholes valuation model. The Black-Scholes valuation model utilizes five inputs: risk-free rate, expected life, volatility, exercise price, and the per share market value of the underlying company. The Corporation holds a portfolio of warrants for generally nonmarketable equity securities with a fair value of $3 million at March 31, 2014, included in "accrued income and other assets" on the consolidated balance sheets. These warrants are primarily from non-public technology companies obtained as part of the loan origination process. The Corporate Development Department is responsible for the warrant valuation process, which includes reviewing all significant inputs for reasonableness, and for providing valuation results to senior management. Increases in any of these inputs in isolation, with the exception of exercise price, would result in a higher fair value. Increases in exercise price in isolation would result in a lower fair value. The Corporation classifies warrants accounted for as derivatives as Level 3.

The Corporation also holds a derivative contract associated with the 2008 sale of its remaining ownership of Visa Inc. (Visa) Class B shares. Under the terms of the derivative contract, the Corporation will compensate the counterparty primarily for dilutive adjustments made to the conversion factor of the Visa Class B to Class A shares based on the ultimate outcome of litigation involving Visa. Conversely, the Corporation will be compensated by the counterparty for any increase in the conversion factor from anti-dilutive adjustments. At March 31, 2014, the fair value of the contract was a liability of $2 million. The recurring fair value of the derivative contract is based on unobservable inputs consisting of management's estimate of the litigation outcome, timing of litigation settlements and payments related to the derivative. Significant increases in the estimate of litigation outcome and the timing of litigation settlements in isolation would result in a significantly higher liability fair value. Significant increases in payments related to the derivative in isolation would result in a significantly lower liability fair value. The Corporation classifies the derivative liability as Level 3.

Nonmarketable equity securities

The Corporation has a portfolio of indirect (through funds) private equity and venture capital investments with a carrying value and unfunded commitments of $12 million and $5 million, respectively, at March 31, 2014. These funds generally cannot be redeemed and the majority are not readily marketable. Distributions from these funds are received by the Corporation as a result of the liquidation of underlying investments of the funds and/or as income distributions. It is estimated that the underlying assets of the funds will be liquidated over a period of up to 16 years. Recently issued federal regulations may require the Corporation to sell certain of these funds prior to liquidation. The investments are accounted for either on the cost or equity method and are individually reviewed for impairment on a quarterly basis by comparing the carrying value to the estimated fair value. These investments may be carried at fair value on a nonrecurring basis when they are deemed to be impaired and written down to fair value. Where there is not a readily determinable fair value, the Corporation estimates fair value for indirect private equity and venture capital investments based on the net asset value, as reported by the fund, after indication that the fund adheres to applicable fair value measurement guidance. For those funds where the net asset value is not reported by the fund, the Corporation derives the fair value of the fund by estimating the fair value of each underlying investment in the fund. In addition to using qualitative information about each underlying investment, as provided by the fund, the Corporation gives consideration to information pertinent to the specific nature of the debt or equity investment, such as relevant market conditions, offering prices, operating results, financial conditions, exit strategy and other qualitative information, as available. The lack of an independent source to validate fair value estimates, including the impact of future capital calls and transfer restrictions, is an inherent limitation in the valuation process. On a quarterly basis, the Corporate Development Department is responsible, with appropriate oversight and approval provided by senior management, for performing the valuation procedures and updating significant inputs, as are primarily provided

by the underlying fund's management. The Corporation classifies fair value measurements of nonmarketable equity securities as Level 3. Commitments to fund additional investments in nonmarketable equity securities recorded at fair value on a nonrecurring basis were not significant at March 31, 2014 or December 31, 2013.

The Corporation also holds restricted equity investments, primarily Federal Home Loan Bank (FHLB) and Federal Reserve Bank (FRB) stock. Restricted equity securities are not readily marketable and are recorded at cost (par value) in "accrued income and other assets" on the consolidated balance sheets and evaluated for impairment based on the ultimate recoverability of the par value. No significant observable market data for these instruments is available. The Corporation considers the profitability and asset quality of the issuer, dividend payment history and recent redemption experience when determining the ultimate recoverability of the par value. The Corporation’s investment in FHLB stock totaled $48 million at both March 31, 2014 and December 31, 2013, and its investment in FRB stock totaled $85 million at both March 31, 2014 and December 31, 2013. The Corporation believes its investments in FHLB and FRB stock are ultimately recoverable at par. Therefore, the carrying amount for these restricted equity investments approximates fair value. The Corporation classifies the estimated fair value of such investments as Level 1.

Other real estate

Other real estate is included in “accrued income and other assets” on the consolidated balance sheets and includes primarily foreclosed property. Foreclosed property is initially recorded at fair value, less costs to sell, at the date of foreclosure, establishing a new cost basis. Subsequently, foreclosed property is carried at the lower of cost or fair value, less costs to sell. Other real estate may be carried at fair value on a nonrecurring basis when fair value is less than cost. Fair value is based upon independent market prices, appraised value or management's estimate of the value of the property. The Special Assets Group obtains updated independent market prices and appraised values, as required by state regulation or deemed necessary based on market conditions, and determines if additional write-downs are necessary. On a quarterly basis, senior management reviews all other real estate and determines whether the carrying values are reasonable, based on the length of time elapsed since receipt of independent market price or appraised value and current market conditions. When management determines that the fair value of other real estate requires additional adjustments, either as a result of a non-current appraisal or when there is no observable market price, the Corporation classifies the other real estate as Level 3.

Deposit liabilities

The estimated fair value of checking, savings and certain money market deposit accounts is represented by the amounts payable on demand. The estimated fair value of term deposits is calculated by discounting the scheduled cash flows using the period-end rates offered on these instruments. As such, the Corporation classifies the estimated fair value of deposit liabilities as Level 2.

Short-term borrowings

The carrying amount of federal funds purchased, securities sold under agreements to repurchase and other short-term borrowings approximates the estimated fair value. As such, the Corporation classifies the estimated fair value of short-term borrowings as Level 1.

Medium- and long-term debt

The carrying value of variable-rate FHLB advances approximates the estimated fair value. The estimated fair value of the Corporation's remaining variable- and fixed-rate medium- and long-term debt is based on quoted market values when available. If quoted market values are not available, the estimated fair value is based on the market values of debt with similar characteristics. The Corporation classifies the estimated fair value of medium- and long-term debt as Level 2.

Credit-related financial instruments

Credit-related financial instruments include unused commitments to extend credit and letters of credit. These instruments generate ongoing fees which are recognized over the term of the commitment. In situations where credit losses are probable, the Corporation records an allowance. The carrying value of these instruments included in "accrued expenses and other liabilities" on the consolidated balance sheets, which includes the carrying value of the deferred fees plus the related allowance, approximates the estimated fair value. The Corporation classifies the estimated fair value of credit-related financial instruments as Level 3.

ASSETS AND LIABILITIES RECORDED AT FAIR VALUE ON A NONRECURRING BASIS

The Corporation may be required, from time to time, 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 that were recognized at fair value below cost at the end of the period. All assets recorded at fair value on a nonrecurring basis were classified as Level 3 at March 31, 2014 and December 31, 2013 and are presented in the following table. No liabilities were recorded at fair value on a nonrecurring basis at March 31, 2014 and December 31, 2013.



(in millions)	Level 3
March 31, 2014
Loans:
Commercial	$	20
Real estate construction	17
Commercial mortgage	74
Total loans	111
Nonmarketable equity securities	2

Other real estate	5
Total assets at fair value	$	135

Level 3 assets recorded at fair value on a nonrecurring basis at March 31, 2014 and December 31, 2013 included loans for which a specific allowance was established based on the fair value of collateral and other real estate for which fair value of the properties was less than the cost basis. For both asset classes, 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.

The following table presents quantitative information related to the significant unobservable inputs utilized in the Corporation's Level 3 recurring fair value measurement as of March 31, 2014 and December 31, 2013. The Corporation's Level 3 recurring fair value measurements include auction-rate securities where fair value is determined using an income approach based on a discounted cash flow model. The inputs in the table below reflect management's expectation of continued illiquidity in the secondary auction-rate securities market due to a lack of market activity for the issuers remaining in the portfolio, a lack of market incentives for issuer redemptions, and the expectation for the low interest rate environment continuing into 2015. The March 31, 2014 workout periods reflect management's view that short-term interest rates could begin to rise in 2015.

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:

(a)	Residential mortgage-backed securities issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises.


(b)	Auction-rate securities.


(c)	Unrealized losses less than $0.5 million.

At March 31, 2014, the Corporation had 169 securities in an unrealized loss position with no credit impairment, including 103 residential mortgage-backed securities, 48 equity and other non-debt auction-rate preferred securities, 17 state and municipal auction-rate securities, one corporate auction-rate debt security and one mutual fund. As of March 31, 2014, approximately 89 percent of the aggregate par value of auction-rate securities have been redeemed or sold since acquisition, of which approximately 95 percent were redeemed at or above cost. The unrealized losses for these securities resulted from changes in market interest rates and liquidity. 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 March 31, 2014.

Sales, calls and write-downs of investment securities available-for-sale resulted in gains of $1 million and no losses for the three months ended March 31, 2014. No securities gains or losses were recognized for the three months ended March 31, 2013. Securities gains and losses are recorded in “net securities gains” on the consolidated statements of comprehensive income, computed based on the adjusted cost of the specific security.

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



(in millions)
March 31, 2014	Amortized Cost		Fair Value
Contractual maturity
Within one year	$	155	$	155
After one year through five years	268		269
After five years through ten years	277		287
After ten years	8,556		8,534
Subtotal	9,256		9,245
Equity and other non-debt securities	245		242
Total investment securities available-for-sale	$	9,501	$	9,487

Included in the contractual maturity distribution in the table above were auction-rate securities with a total amortized cost and fair value of $25 million and $24 million, respectively. Auction-rate securities are long-term, floating rate instruments for which interest rates are reset at periodic auctions. At each successful auction, the Corporation has the option to sell the security at par value. Additionally, the issuers of auction-rate securities generally have the right to redeem or refinance the debt. As a result, the expected life of auction-rate securities may differ significantly from the contractual life. Also included in the table above were residential mortgage-backed securities with total amortized cost and fair value of $9.1 billion. The actual cash flows of mortgage-backed securities may differ from contractual maturity as the borrowers of the underlying loans may exercise prepayment options.

At March 31, 2014, investment securities with a carrying value of $3.3 billion were pledged where permitted or required by law to secure $2.3 billion of liabilities, primarily public and other deposits of state and local government agencies and 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.

(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. PCI loans are included in the substandard category. 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 page F-58 in the Corporation's 2013 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 tables detail the recorded balance at March 31, 2014 and 2013 of loans considered to be TDRs that were restructured during the three months ended March 31, 2014 and 2013, by type of modification.

(a)	Primarily represents loan balances where terms were extended 90 days or more at or above contractual interest rates.


(b)	Loan restructurings whereby the original loan is restructured into two notes: an "A" note, which generally reflects the portion of the modified loan which is expected to be collected; and a "B" note, which is either fully charged off or exchanged for an equity interest.


(c)	Primarily loans to real estate developers.


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


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

At March 31, 2014 and December 31, 2013, commitments to lend additional funds to borrowers whose terms have been modified in TDRs totaled $4 million.

The majority of the modifications considered to be TDRs that occurred during the three months ended March 31, 2014 and 2013 were principal deferrals. The Corporation charges interest on principal balances outstanding during deferral periods. Additionally, none of the modifications involved forgiveness of principal. As a result, the current and future financial effects of the recorded balance of loans considered to be TDRs that were restructured during the three months ended March 31, 2014 and 2013 were insignificant.

On an ongoing basis, the Corporation monitors the performance of modified loans to their restructured terms. In the event of a subsequent default, the allowance for loan losses continues to be reassessed on the basis of an individual evaluation of the loan.

The following table presents information regarding the recorded balance at March 31, 2014 and 2013 of loans modified by principal deferral during the twelve months ended March 31, 2014 and 2013, and those principal deferrals which experienced a subsequent default during the three months ended March 31, 2014 and 2013. 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.

During the twelve months ended March 31, 2014 and 2013, loans with a carrying value of $6 million and $4 million, respectively, were modified by interest rate reduction and loans with a carrying value of $8 million and $30 million, respectively, were restructured into two notes (AB note restructures). For reduced-rate loans and AB note restructures, a subsequent payment default is defined in terms of delinquency, when a principal or interest payment is 90 days past due. There were no subsequent payment defaults of reduced-rate loans or AB note restructures during the three months ended March 31, 2014 and 2013.

Purchased Credit-Impaired Loans

Acquired loans are initially recorded at fair value with no carryover of any allowance for loan losses. Loans acquired with evidence of credit quality deterioration at acquisition for which it was probable that the Corporation would not be able to collect all contractual amounts due were accounted for as PCI loans. The Corporation aggregated the acquired PCI loans into pools of loans based on common risk characteristics.

No allowance for loan losses was required on the acquired PCI loan pools at both March 31, 2014 and December 31, 2013. The nonaccretable yield on PCI loans was $9 million at March 31, 2014. The carrying amount of acquired PCI loans included in the consolidated balance sheet and the related outstanding balance at March 31, 2014 and December 31, 2013 were as follows.

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 reviewed 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 beyond certain risk limits. At March 31, 2014, counterparties with bilateral collateral agreements had pledged $117 million of marketable investment securities and deposited $3 million of cash with the Corporation to secure the fair value of contracts in an unrealized gain position, and the Corporation had pledged $8 million of investment securities and posted $19 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.

The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability position on March 31, 2014 was $7 million, for which the Corporation had pledged collateral of $3 million in the normal course of business. The credit-risk-related contingent features require the Corporation’s debt to maintain an investment grade credit rating from each of the major credit rating agencies. If the Corporation’s debt were to fall below investment grade, the counterparties to the derivative instruments could require additional overnight collateral on derivative instruments in net liability positions. If the credit-risk-related contingent features underlying these agreements had been triggered on March 31, 2014, the Corporation would have been required to assign an additional $4 million of collateral to its counterparties.

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

Table of Contents

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 conducting hedging transactions 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)	Notional or contractual amounts, which represent the extent of involvement in the derivatives market, are used to determine the contractual cash flows required in accordance with the terms of the agreement. These amounts are typically not exchanged, significantly exceed amounts subject to credit or market risk and are not reflected in the consolidated balance sheets.

(b)

Net derivative assets are included in “accrued income and other assets” and net derivative liabilities are included in “accrued expenses and other liabilities” on the consolidated balance sheets. Included in the fair value of net derivative assets and net derivative liabilities are credit valuation adjustments reflecting counterparty credit risk and credit risk of the Corporation. The fair value of net derivative assets included credit valuation adjustments for counterparty credit risk totaled $2 million at both March 31, 2014 and December 31, 2013.

Risk Management

As an end-user, the Corporation employs a variety of financial instruments for risk management purposes, including cash instruments, such as investment securities, as well as derivative instruments. Activity related to these instruments is centered predominantly in the interest rate markets and mainly involves interest rate swaps. Various other types of instruments also may

be used to manage exposures to market risks, including interest rate caps and floors, total return swaps, foreign exchange forward contracts and foreign exchange swap agreements.

As part of a fair value hedging strategy, the Corporation entered into interest rate swap agreements for interest rate risk management purposes. These interest rate swap agreements effectively modify the Corporation’s exposure to interest rate risk by converting fixed-rate debt to a floating rate. These agreements involve the receipt of fixed-rate interest amounts in exchange for floating-rate interest payments over the life of the agreement, without an exchange of the underlying principal amount. Risk management fair value interest rate swaps generated net interest income of $18 million for both the three-month periods ended March 31, 2014 and 2013. The Corporation recognized an insignificant amount of net gains (losses) in "other noninterest income" in the consolidated statements of comprehensive income for the ineffective portion of risk management derivative instruments designated as fair value hedges of fixed-rate debt for both the three-month periods ended March 31, 2014 and 2013.

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. The Corporation recognized an insignificant amount of net gains on risk management derivative instruments used as economic hedges in "other noninterest income" in the consolidated statements of comprehensive income for both the three months ended March 31, 2014 and 2013.

The following table summarizes the expected weighted average remaining maturity of the notional amount of risk management interest rate swaps and the weighted average interest rates associated with amounts expected to be received or paid on interest rate swap agreements as of March 31, 2014 and December 31, 2013.



			Weighted Average
(dollar amounts in millions)	Notional Amount		Remaining Maturity (in years)	Receive Rate		Pay Rate (a)
March 31, 2014
Swaps - fair value - receive fixed/pay floating rate
Medium- and long-term debt designation	$	1,450	3.2	5.45	%	0.35	%
December 31, 2013
Swaps - fair value - receive fixed/pay floating rate
Medium- and long-term debt designation	1,450		3.4	5.45		0.38


(a)	Variable rates paid on receive fixed swaps are based on six-month LIBOR rates in effect at March 31, 2014 and December 31, 2013.

Management believes these hedging strategies achieve the desired relationship between the rate maturities of assets and funding sources which, in turn, reduce the overall exposure of net interest income to interest rate risk, although there can be no assurance that such strategies will be successful.

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 speculative position within the limits described above, the Corporation recognized an insignificant amount of net gains in “other noninterest income” in the consolidated statements of comprehensive income for both the three-month periods ended March 31, 2014 and 2013.

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)	March 31, 2014		December 31, 2013
Unused commitments to extend credit:
Commercial and other	$	26,925	$	27,728
Bankcard, revolving check credit and home equity loan commitments	1,923		1,889
Total unused commitments to extend credit	$	28,848	$	29,617
Standby letters of credit	$	4,171	$	4,297
Commercial letters of credit	96		103
Other credit-related financial instruments	2		2

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. At March 31, 2014 and December 31, 2013, the allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, was $37 million and $36 million, 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 $25 million and $28 million at March 31, 2014 and December 31, 2013, respectively, 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 2020. 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 $250 million and $259 million, respectively, of the $4.3 billion and $4.4 billion standby and commercial letters of credit outstanding at March 31, 2014 and December 31, 2013, respectively.

The carrying value of the Corporation’s standby and commercial letters of credit, included in “accrued expenses and other liabilities” on the consolidated balance sheets, totaled $65 million at March 31, 2014, including $53 million in deferred fees and $12 million in the allowance for credit losses on lending-related commitments. At December 31, 2013, the comparable amounts were $59 million, $51 million and $8 million, respectively.

The following table presents a summary of criticized standby and commercial letters of credit at March 31, 2014 and December 31, 2013. 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 March 31, 2014 and December 31, 2013, the total notional amount of the credit risk participation agreements was approximately $583 million and $614 million, respectively, and the fair value, included in customer-initiated interest rate contracts recorded in "accrued expenses and other liabilities" on the consolidated balance sheets, was insignificant for each period. 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 approximately $6 million and $7 million at March 31, 2014 and December 31, 2013, 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 March 31, 2014, the weighted average remaining maturity of outstanding credit risk participation agreements was 2.5 years.

In 2008, the Corporation sold its remaining ownership of Visa Class B shares and entered into a derivative contract. Under the terms of the derivative contract, the Corporation will compensate the counterparty primarily for dilutive adjustments made to the conversion factor of the Visa Class B shares to Class A shares based on the ultimate outcome of litigation involving Visa. Conversely, the Corporation will be compensated by the counterparty for any increase in the conversion factor from anti-dilutive adjustments. The notional amount of the derivative contract was equivalent to approximately 780,000 Visa Class B shares. The fair value of the derivative liability, included in "accrued expenses and other liabilities" on the consolidated balance sheets, was $2 million at both March 31, 2014 and December 31, 2013.

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 LIHTC. The Corporation also directly invests in limited partnerships and LLCs which invest in community development projects which generate similar tax credits to investors. 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. While the partnership/LLC agreements allow the limited partners/investor members, through a majority vote, to remove the general partner/managing member, this right is not deemed to be substantive as the general partner/managing member can only be removed for cause.

The Corporation accounts for its interests in LIHTC entities using the proportional amortization method. Exposure to loss as a result of the Corporation’s involvement with LIHTC entities at March 31, 2014 was limited to approximately $381 million. Ownership interests in other community development projects which generate similar tax credits to investors (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 other tax credit entities at March 31, 2014 was limited to approximately $13 million.

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 ($136 million at March 31, 2014). 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 three months ended March 31, 2014 and 2013.

The following table summarizes the impact of these tax credit entities on line items on the Corporation’s consolidated statements of comprehensive income.

NOTE 11 - INCOME TAXES AND TAX-RELATED ITEMS

Net unrecognized tax benefits were $11 million at both March 31, 2014 and December 31, 2013. The Corporation anticipates that it is reasonably possible that final settlement of federal and state tax issues will result in a decrease in net unrecognized tax benefits of $7 million within the next twelve months. Included in "accrued expense and other liabilities" on the consolidated balance sheets was a $2 million liability for tax-related interest and penalties at both March 31, 2014 and December 31, 2013.

Net deferred tax assets were $224 million at March 31, 2014, compared to $256 million at December 31, 2013. The decrease of $32 million in net deferred tax assets resulted primarily from a decrease in unrealized losses on investment securities available-for-sale recognized in other comprehensive income. Deferred tax assets were evaluated for realization and it was determined that no valuation allowance was needed at both March 31, 2014 and December 31, 2013. This conclusion was based on available evidence of loss carryback capacity, projected future reversals of existing taxable temporary differences and assumptions made regarding future events.

In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) may review and/or challenge specific interpretive tax positions taken by the Corporation with respect to those transactions. The Corporation believes that its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The IRS, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law.

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

NOTE 12 - CONTINGENT LIABILITIES

Legal Proceedings

Comerica Bank, a wholly owned subsidiary of the Corporation, was named a third-party defendant in Butte Local Development v. Masters Group v. Comerica Bank (“the case”), a lender liability case filed on November 16, 2011. The jury trial commenced January 6, 2014, in the Montana Second District Judicial Court for Silver Bow County in Butte, Montana ("the court"). The claims underlying the case against the Bank grew out of an initial, two-year $9 million revolving line of credit loan extended by the Bank to Masters in July 2006. The loan was subsequently increased to $10.5 million and expired by its terms in July 2008 and was later paid in full through collection actions initiated by the Bank in December 2008, following a default by Masters. Masters alleged that the Bank wrongfully collected the loan, causing Masters to cease operations, and claimed that as a result, they failed to repay a $200,000 loan that they owed to Butte Local Development (“BLD”). Masters did not dispute that it was required to repay the $10.5 million loan, but contended the Bank should have continued to give it more time.

Starting in July 2013, the Bank attempted to settle the case by offering to pay the debt owed by Masters to BLD. The Bank anticipated that such a settlement would improve the Bank's chances of defending the case in Federal court, the court in which Masters would have been required to sue the Bank, absent BLD’s claim. Those discussions and consideration of the settlement offer continued for several months. Accordingly, on September 30, 2013, the Corporation believed that a nominal loss was probable and recorded legal reserves for the settlement offer made to BLD.

On January 17, 2014, a jury awarded Masters $52 million for its claims against the Bank. The jury also awarded BLD $275,000 for its claims against Masters. Following the jury’s decision on the case, the Corporation increased its reserve for litigation-related expense, effective as of December 31, 2013, to $52 million.

On January 23, 2014, Masters filed motions for additional claims against the Corporation related to the case seeking court costs, pre-judgment interest, punitive damages above the statutory maximum permitted by the State of Montana and attorneys' fees. In March 2014, the court declined to increase the punitive damage award against the Bank above the amount awarded by the jury and declined the request by Masters for a percentage of the jury award in attorney's fees and instead allowed fees based on

hourly rates. The Corporation stipulated to $2 million of attorney's fees and costs but reserved the right to appeal Masters' entitlement to such fees and costs. The Corporation accordingly increased its reserve related to the case to $54 million.

Masters filed a notice of their intent to appeal certain aspects of the court's ruling. The Corporation believes that it has meritorious defenses for this litigation and has appealed the jury's decision and certain rulings on the case, including the award for attorneys' fees, to the Montana Supreme Court, the sole appellate court for the state of Montana.

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 that 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, consolidated results of operations or consolidated cash flows. Legal fees of $5 million and $8 million were included in "other noninterest expenses" on the consolidated statements of income for the three months ended March 31, 2014 and 2013, 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 $85 million at March 31, 2014. This estimated aggregate range of reasonably possible losses is based upon currently available information for those proceedings in which the Corporation is involved, taking into account the Corporation’s best estimate of such losses for those cases for which such estimate can be made. For certain cases, the Corporation does not believe that an estimate can currently be made. The Corporation’s estimate involves significant judgment, given the varying stages of the proceedings (including the fact that 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 that the ultimate resolution of these matters, if unfavorable, may be material to the Corporation's consolidated financial condition, consolidated results of operations or consolidated 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. These 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 segments and methodologies in effect at March 31, 2014.

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.

RESULTS OF OPERATIONS

Net income for the three months ended March 31, 2014 was $139 million, an increase of $5 million from $134 million reported for the three months ended March 31, 2013. This increase was primarily the result of decreases of $10 million in noninterest expenses and $7 million in the provision for credit losses, partially offset by decreases of $6 million in net interest income and $5 million in noninterest income. Net income per diluted common share was $0.73 for the three months ended March 31, 2014, compared to $0.70 for the same period one year ago. Average diluted common shares were 187 million for both the three-month periods ended March 31, 2014 and 2013.

Full-Year 2014 Outlook Compared to Full-Year 2013

Management expectations for full-year 2014 compared to 2013, assuming a continuation of the current economic and low rate environment, are as follows:


•	Average loan growth consistent with 3 percent growth achieved in 2013, reflecting stabilization in Mortgage Banker Finance near average fourth quarter 2013 level and continued focus on pricing and structure discipline.


•	Net interest income modestly lower, reflecting a decline in purchase accounting accretion, to $20 million to $30 million, and the effect of continued pressure from the low rate environment, partially offset by loan growth.


•	Provision for credit losses and net charge-offs stable. Increases to the allowance for credit losses due to loan growth offset by continued strong credit quality.


•	Noninterest income modestly lower, reflecting stable customer-driven fee income and lower noncustomer-driven income. Growth in fiduciary income and card fees offset by lower capital market activity.


•	Noninterest expenses lower, reflecting lower litigation-related expenses and a more than 50 percent decrease in pension expense, to $35 million to $40 million.


•	Income tax expense to approximate 32 percent of pre-tax income, reflecting the change in accounting for affordable housing projects that qualify for the low-income housing tax credit described below. The impact of the increase in the effective tax rate is fully offset by a related increase in noninterest income, resulting in no impact to net income.

The Corporation early adopted an amendment to U.S. generally accepted accounting principles in the first quarter 2014 related to the accounting for affordable housing projects that qualify for the low-income housing tax credit. Amortization of the initial investment cost of qualifying projects is now recorded in the provision for income taxes together with the tax credits and benefits received. Previously, the amortization was recorded as a reduction to other noninterest income. All prior period amounts in this financial review have been restated to reflect the adoption of the amendment, which resulted in offsetting increases to other noninterest income and the provision for income taxes of $13 million for the three months ended March 31, 2013 ($56 million for full-year 2013). The adoption had no impact on net income for any period presented.

Net Interest Income

Net interest income was $410 million for the three months ended March 31, 2014, a decrease of $6 million compared to $416 million for the three months ended March 31, 2013. The decrease in net interest income resulted primarily from a decrease in yields on earning assets, partially offset by a the benefit provided by a decrease in funding costs and an increase in average earning assets. Average earning assets increased $1.3 billion, or 2 percent, to $59.9 billion for the three months ended March 31, 2014, compared to $58.6 billion for the same period in 2013. The increase in average earning assets primarily reflected increases of $1.6 billion in average interest-bearing deposits with banks and $458 million in average loans, partially offset by a decrease of $739 million in average investment securities available-for-sale. The net interest margin (FTE) for the three months ended March 31, 2014 decreased 11 basis points to 2.77 percent, from 2.88 percent for the comparable period in 2013, primarily from decreased yields on loans and the impact of an increase in excess liquidity, partially offset by lower deposit rates and improved yields on mortgage-backed investment securities. The decrease in loan yields was primarily the result of the impact of a lower rate environment, repayments on higher-yielding loans, positive credit quality migration throughout the portfolio and shifts in the average loan portfolio mix. Yields on mortgage-backed investment securities increased primarily due to decreased premium amortization resulting from slower prepayment speeds, largely reflecting the cumulative impact of a retrospective adjustment made in the three months ended March 31, 2014. Excess liquidity reduced the net interest margin by approximately 24 basis points and 17 basis points in the three months ended March 31, 2014 and 2013, respectively. Excess liquidity was represented by $5.3 billion and $3.7 billion of average balances deposited with the Federal Reserve Bank (FRB) in the three months ended March 31, 2014 and 2013, respectively, included in “interest-bearing deposits with banks” on the consolidated balance sheets. The "Quarterly Analysis of Net Interest Income & Rate/Volume - Fully Taxable Equivalent" table above provides an analysis of net interest income (FTE) for the three months ended March 31, 2014 and 2013 and details the components of the change in net interest income on a FTE basis for the three months ended March 31, 2014 compared to the same period in the prior year.

Provision for Credit Losses

The provision for credit losses was $9 million for the three months ended March 31, 2014, compared to $16 million for the same period in 2013. 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. For a discussion of the allowance for loan losses and the methodology used in the determination of the allowance for loan losses, refer to the "Credit Risk" and "Critical Accounting Policies" sections of this financial review. The provision for loan losses was $8 million for the three months ended March 31, 2014, compared to $12 million for the three months ended March 31, 2013. Credit quality in the loan portfolio continued to improve in the three months ended March 31, 2014, compared to the same period in the prior year. Improvements in credit quality included a decline of $755 million in the Corporation's criticized loan list from March 31, 2013 to March 31, 2014. Reflected in the decline in criticized loans was a decrease in nonaccrual loans of $177 million. The Corporation's criticized loan list is consistent with loans in the Special Mention, Substandard and Doubtful categories defined by regulatory authorities.

Net loan charge-offs in the three months ended March 31, 2014 decreased $12 million to $12 million, or 0.10 percent of average total loans, compared to $24 million, or 0.21 percent, for the three months ended March 31, 2013. The $12 million decrease in net loan charge-offs in the three months ended March 31, 2014, compared to the same period in 2013, reflected decreases in most business lines, with the largest decreases in general Middle Market and Small Business, partially offset by increases in Technology and Life Sciences and Commercial Real Estate.

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 credit losses on lending-related commitments was $1 million in the three months ended March 31, 2014, compared to $4 million in the three months ended March 31, 2013. The $3 million decrease reflected a $4 million decrease in the provision for unfunded commitments, partially offset by a $1 million increase in the provision for letters of credit. Lending-related commitment charge-offs were insignificant for the three months ended March 31, 2014 and 2013.

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.

benefits expense and small decreases in several other categories of noninterest expense. Salaries and benefits expense decreased primarily due to a decrease in pension expense, partially offset by increases in payroll taxes and share-based compensation expense.

STRATEGIC LINES OF BUSINESS

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.

Business Segments

The Corporation's operations are strategically aligned into three major business segments: the Business Bank, the Retail Bank and Wealth Management. These business segments are differentiated based upon the products and services provided. In addition to the three major business segments, Finance 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. Note 13 to the consolidated financial statements describes the business activities of each business segment and presents financial results of these business segments for the three months ended March 31, 2014 and 2013.

The following table presents net income (loss) by business segment.

The Business Bank's net income of $198 million for the three months ended March 31, 2014 was unchanged compared to the three months ended March 31, 2013. Net interest income (FTE) of $371 million decreased $4 million in the three months ended March 31, 2014, primarily due to lower loan yields, partially offset by an increase in accretion of the purchase discount on the acquired loan portfolio, the benefit provided by an increase of $174 million in average loans and a decrease in net funds transfer pricing (FTP) charges. Average deposits increased $1.5 billion. The provision for credit losses decreased $4 million to $16 million for the three months ended March 31, 2014, compared to the same period in the prior year, primarily due to improved credit quality. Net credit-related charge-offs of $11 million decreased $5 million in the three months ended March 31, 2014, compared to the three months ended March 31, 2013, primarily reflecting a decrease in general Middle Market, partially offset by increases in Technology and Life Sciences and Commercial Real Estate. Noninterest income of $87 million for the three months ended March 31, 2014 decreased $3 million from the comparable period in the prior year, primarily due to small decreases in several noninterest income categories. Noninterest expenses of $146 million for the three months ended March 31, 2014 were unchanged compared to the same period in the prior year, as a decrease in salaries and benefits expense of $3 million and smaller decreases in several other categories of noninterest expenses were offset by an increase in corporate overhead expense of $4 million.

Net income for the Retail Bank of $9 million for the three months ended March 31, 2014 decreased $1 million, compared to $10 million for the three months ended March 31, 2013. Net interest income (FTE) of $146 million decreased $9 million in the three months ended March 31, 2014, primarily due to a decrease in net FTP credits, lower loan yields and a decrease in accretion of the purchase discount on the acquired loan portfolio, partially offset the benefit provided by a $105 million increase in average loans and lower deposit rates. The provision for credit losses of $2 million and net credit-related charge-offs of $4 million for the three months ended March 31, 2014 each decreased $4 million from the comparable period in the prior year, both primarily reflecting a decrease in Small Business. Noninterest income of $41 million for the three months ended March 31, 2014 was unchanged compared to the three months ended March 31, 2013. Noninterest expenses of $171 million for the three months ended March 31, 2014 decreased $4 million from the comparable period in the prior year, primarily due to a decrease in salaries and benefits expense of $2 million and small decreases in several other noninterest expense categories.

Wealth Management's net income of $26 million for the three months ended March 31, 2014 increased $1 million, compared to $25 million for the three months ended March 31, 2013. Net interest income (FTE) of $46 million for the three months ended March 31, 2014 was unchanged compared to the three months ended March 31, 2013. The benefit provided by a $179

Table of Contents

million increase in average loans was offset by a decline in loan yields. The provision for credit losses was a benefit of $8 million for the three months ended March 31, 2014, compared to a benefit of $6 million for the three months ended March 31, 2013, primarily due to improvements in credit quality. Net credit-related recoveries were $3 million for the three months ended March 31, 2014, compared to an insignificant amount for the three months ended March 31, 2013. Noninterest income of $64 million decreased $1 million from the comparable period in the prior year, primarily reflecting a $2 million decrease in securities trading income and smaller decreases in several other noninterest income categories, partially offset by a $2 million increase in fiduciary income. Noninterest expenses of $78 million for the three months ended March 31, 2014 decreased $1 million from the three months ended March 31, 2013, primarily due to a $3 million decrease in salaries and benefits expense, partially offset by small increases in several other noninterest expense categories.

The net loss in the Finance segment was $92 million for the three months ended March 31, 2014, compared to a net loss of $98 million for the three months ended March 31, 2013. Net interest expense (FTE) of $158 million for the three months ended March 31, 2014 decreased $9 million, compared to the three months ended March 31, 2013, primarily reflecting a decrease in net FTP expense as a result of lower net rates paid to the business segments under the Corporation's internal FTP methodology as well as an increase in interest earned on the Corporation's mortgage-backed investment securities.

FINANCIAL CONDITION

Total assets were $65.7 billion at March 31, 2014, an increase of $457 million from $65.2 billion at December 31, 2013, primarily reflecting increases of $1.0 billion in total loans, $180 million in investment securities available-for-sale and $103 million in accrued income and other assets, partially offset by an $877 million decrease in interest-bearing deposits with banks. On an average basis, total assets increased $103 million to $64.7 billion in the first quarter 2014, compared to $64.6 billion in the fourth quarter 2013, resulting primarily from an increase of $1.0 billion in average loans, largely offset by a decrease of $952 million in average interest-bearing deposits with banks.

The following tables provide information about the change in the Corporation's average loan portfolio in the first quarter 2014, compared to the fourth quarter 2013.

Average loans for the three months ended March 31, 2014 increased $1.0 billion, compared to the three months ended December 31, 2013, led by increases of $679 million, or 2 percent in average commercial loans and $231 million, or 2 percent in average combined commercial mortgage and real estate construction loans. The $679 million increase in average commercial loans primarily reflected an increase in Middle Market ($707 million), partially offset by a decrease in Mortgage Banker Finance ($223 million). The decline in Mortgage Banker Finance, which provides mortgage warehousing lines, primarily reflected a decline in residential mortgage activity. The increase in Middle Market primarily reflected increases in general Middle Market ($284 million), Energy ($224 million) and Technology and Life Sciences ($202 million), partially offset by a decrease in Entertainment ($117 million). In general, Middle Market serves customers with annual revenue between $20 million and $500 million; while Corporate serves customers with revenue over $500 million. Changes in average total loans by geographic market is provided in the table above.

Table of Contents

of $14 million at March 31, 2014, compared to a net unrealized loss of $107 million at December 31, 2013. On an average basis, investment securities available-for-sale decreased $83 million in the first quarter 2014, compared to the fourth quarter 2013. Average unrealized losses increased $32 million in the first quarter 2014, compared to the fourth quarter 2013.

Total liabilities increased $324 million to $58.4 billion at March 31, 2014, compared to $58.1 billion at December 31, 2013, primarily due to an increase of $378 million in interest-bearing deposits. On an average basis, total liabilities decreased $116 million in the first quarter 2014, compared to the fourth quarter 2013, primarily due to decreases of $296 million in noninterest-bearing deposits and $94 million in short-term borrowings, partially offset by an increase of $297 million in interest-bearing deposits. The decrease in average noninterest-bearing deposits primarily reflected decreases in Corporate Banking ($540 million) and Private Banking ($126 million), partially offset by an increase Middle Market ($389 million). The increase in Middle Market was driven by an increase in balances in Technology and Life Sciences ($531 million). The increase in average interest-bearing deposits primarily reflected increases of $231 million in money market and interest-bearing checking deposits, largely the result of an increase in Corporate Banking ($232 million), and $31 million in customer certificates of deposit. By geographic market, average total deposits increased in Texas ($339 million) and Michigan ($141 million) and decreased in California ($437 million) and Other Markets ($87 million).

The Corporation has a process to periodically conduct stress tests to evaluate potential impacts to the Corporation's forecasted financial condition under various economic scenarios. These stress tests are a regular part of the Corporation's overall risk management and capital planning process. The same forecasting process is also used by the Corporation to conduct the stress test that was part of the Federal Reserve's Comprehensive Capital Analysis and Review (CCAR). For additional information about risk management processes, refer to the "Risk Management" section of this financial review.

The Federal Reserve completed its 2014 CCAR review in March 2014 and did not object to Comerica's capital plan and capital distributions contemplated in the plan. Comerica's capital plan provides for up to $236 million in share repurchases for the four-quarter period ending March 31, 2015, as well as the authority to fully redeem $150 million par value of subordinated notes due 2024. The notes are callable at par on or after July 15, 2014 and were recorded at a carrying value of $183 million at March 31, 2014. Due to the lack of certainty about the possible execution and timing of the call, the impact of the call is not reflected in the outlook for 2014. Comerica's capital plan further included a 1-cent increase in the quarterly dividend to $0.20 per common share. The dividend proposal was approved by the Board of Directors on April 22, 2014.

On April 22, 2014, the Board of Directors of the Corporation authorized the repurchase of up to an additional 2.0 million shares of Comerica Incorporated outstanding common stock, in addition to the 5.1 million shares remaining at March 31, 2014 under the Board's prior authorizations for the share repurchase program initially approved in November 2010. Including the April 22, 2014 authorization, a total of 30.3 million shares has been authorized for repurchase under the share repurchase program since its inception in 2010. In November 2010, the Board authorized the purchase of up to all 11.5 million of the Corporation's original outstanding warrants. There is no expiration date for the Corporation's share repurchase program.

(a)	Maximum number of shares and warrants that may yet be purchased under the publicly announced plans or programs. Does not reflect April 22, 2014 share repurchase authorization for up to an additional 2.0 million shares.


(b)	Includes approximately 180,000 shares purchased pursuant to deferred compensation plans and shares purchased from employees to pay for taxes related to restricted stock vesting under the terms of an employee share-based compensation plan during the three months ended March 31, 2014. These transactions are not considered part of the Corporation's repurchase program.

(c)

The Corporation made no repurchases of warrants under the repurchase program during the three months ended March 31, 2014. Upon exercise of a warrant, the number of shares with a value equal to the aggregate exercise price is withheld from an exercising warrant holder as payment (known as a "net exercise provision"). During the three months ended March 31, 2014, the Corporation withheld the equivalent of approximately 8,000 shares to cover an aggregate of $235,000 in exercise price and issued approximately 5,000 shares to the exercising warrant holders. Shares withheld in connection with the net exercise provision are not included in the total number of shares or warrants purchased in the above table.

Risk-based regulatory capital standards are designed to make regulatory capital requirements more sensitive to differences in credit risk profiles among banking institutions and to account for off-balance sheet exposure. Assets and off-balance sheet items are assigned to broad risk categories, each with specified risk-weighting factors. The resulting capital ratios represent capital as a percentage of total risk-weighted assets and off-balance sheet items.

The Corporation's capital ratios exceeded minimum regulatory requirements as follows:

(a)	See Supplemental Financial Data section for reconcilements of non-GAAP financial measures.


(b)	March 31, 2014 capital and ratios are estimated.

In July 2013, U.S. banking regulators issued a final rule for the U.S. adoption of the Basel III regulatory capital framework. The regulatory framework includes a more conservative definition of capital, two new capital buffers - a conservation buffer and a countercyclical buffer, new and more stringent risk weight categories for assets and off-balance sheet items, and a supplemental leverage ratio. As a banking organization subject to the standardized approach, the rules will be effective for the Corporation on January 1, 2015, with certain transition provisions fully phased in on January 1, 2018.

According to the rule, the Corporation will be subject to the capital conservation buffer of 2.5 percent, when fully phased in, to avoid restrictions on capital distributions and discretionary bonuses. However, the rules do not subject the Corporation to the capital countercyclical buffer of up to 2.5 percent or the supplemental leverage ratio. The Corporation estimates the March 31, 2014 common equity Tier 1 and Tier 1 risk-based ratio would be 10.3 percent if calculated under the final rule, excluding most elements of accumulated other comprehensive income from regulatory capital. The Corporation's March 31, 2014 estimated common equity Tier 1 and Tier 1 capital ratios exceed the minimum required by the final rule (7 percent and 8.5 percent, respectively, including the fully phased-in capital conservation buffer). For a reconcilement of these non-GAAP financial measures, refer to the "Supplemental Financial Data" section of this financial review.

The Corporation expects that U.S. banking regulators will establish an additional capital buffer for banking organizations deemed systemically important to the U.S. financial system (Domestic Systemically Important Banks, or "D-SIB"). If designated as a D-SIB by the U.S. banking regulators, the Corporation would be subject to the additional buffer. While the level and timing of a D-SIB buffer is not currently known, the Corporation expects to exceed all required capital levels within regulatory timelines.

On October 24, 2013, U.S. banking regulators issued a Notice of Proposed Rulemaking that would implement a quantitative liquidity requirement in the U.S. (the proposed rule) generally consistent with the Liquidity Coverage Ratio (LCR) minimum liquidity measure established under the Basel III liquidity framework. Under the proposed rule, the Corporation would be subject

Table of Contents

to a modified LCR standard, which requires a financial institution to hold a buffer of high-quality, liquid assets to fully cover net cash outflows under a 21-day systematic liquidity stress scenario. Under the proposal, the LCR rules would be fully phased in on January 1, 2017, with a transition period beginning January 1, 2015. The Corporation is currently evaluating the potential impact of the proposed rule; however, we expect to meet the final requirements adopted by U.S. banking regulators within the required timetable. Uncertainty exists as to the final form and timing of the proposed rule, and balance sheet dynamics may vary in the future. As a result the Corporation may decide to consider additional liquidity management initiatives. The Basel III liquidity framework includes a second minimum liquidity measure, the Net Stable Funding Ratio (NSFR), which requires the amount of available longer-term, stable sources of funding to be at least 100 percent of the required amount of longer-term stable funding over a one-year period. The Basel Committee on Banking Supervision is in the process of reviewing the proposed NSFR standard and evaluating its impact on the banking system. U.S. banking regulators have announced that they expect to issue proposed rulemaking to implement the NFSR in advance of its scheduled global implementation in 2018. While uncertainty exists in the final form and timing of the U.S. rule implementing the NSFR and whether or not the Corporation will be subject to the full requirements, the Corporation is closely monitoring the development of the rule.

RISK MANAGEMENT

The following updated information should be read in conjunction with the "Risk Management" section on pages F-23 through F-40 in the Corporation's 2013 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 Corporation disaggregates the loan portfolio into segments for purposes of determining the allowance for credit losses. These segments are based on the level at which the Corporation develops, documents and applies a systematic methodology to determine the allowance for credit losses. The Corporation's portfolio segments are business loans and retail loans. Business loans are defined as those belonging to the commercial, real estate construction, commercial mortgage, lease financing and international loan portfolios. Retail loans consist of traditional residential mortgage, home equity and other consumer loans. The allowance for loan losses includes specific allowances, based on individual evaluations of certain loans, and allowances for homogeneous pools of loans with similar risk characteristics.

While the overall credit quality of the loan portfolio was strong in the first quarter 2014, economic uncertainty continued to be a consideration when determining the appropriateness of the allowance for loan losses. Events such as the widespread bad weather in the U.S. in the first quarter 2014 and the volatile geopolitical situation in Eastern Europe added uncertainty, while the U.S. economic outlook appeared to be relatively more favorable.

The allowance for loan losses was $594 million at March 31, 2014, compared to $598 million at December 31, 2013, a decrease of $4 million, or 1 percent. The decrease resulted primarily from a reduction in specific reserves and a decrease in retail reserves, partially offset by higher loan balances. Acquired loans were initially recorded at fair value, which included an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for loan losses was recorded for these loans at acquisition. Methods utilized to estimate the required allowance for loan losses for acquired loans not deemed credit-impaired at acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid principal balance less the remaining purchase discount, either on an individually evaluated basis or based on the pool of acquired loans not deemed credit-impaired at acquisition within each risk rating, as applicable. At March 31, 2014, there was $17 million of purchase discount remaining, compared to $21 million of purchase discount remaining at December 31, 2013. No allowance for loan losses was required on acquired loans for either period.

The total allowance for loan losses is sufficient to absorb incurred losses inherent in the total loan portfolio. Unanticipated economic events, including political, economic and regulatory instability could cause changes in the credit characteristics of the portfolio and result in an unanticipated increase in the allowance. Loss emergence periods, which are used to determine the most appropriate default horizon associated with the calculation of probabilities of default, tend to lengthen during benign economic periods and shorten during periods of economic distress. Considered in isolation, lengthening the loss emergence period assumption would result in an increase to the allowance for loan losses. In addition, inclusion of other industry-specific portfolio exposures in the allowance, as well as significant increases in the current portfolio exposures, could also increase the amount of the allowance. Any of these events, or some combination thereof, may result in the need for additional provision for loan losses in order to maintain an allowance that complies with credit risk and accounting policies.

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 $37 million at March 31, 2014 compared to $36 million at December 31, 2013. The $1 million increase in the allowance for credit losses on lending-related commitments resulted primarily from an increase of $4 million in reserves for standby letters of credit, partially offset by a decrease of $3 million in reserves for unused commitments to extend credit.

Nonperforming Assets

Nonperforming assets include loans on nonaccrual status, troubled debt restructured loans (TDRs) which have been renegotiated to less than the original contractual rates (reduced-rate loans) and foreclosed property. TDRs include performing and nonperforming loans. Nonperforming TDRs are either on nonaccrual or reduced-rate status. Nonperforming assets do not include purchased credit impaired (PCI) loans.

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

Nonperforming assets decreased $31 million to $352 million at March 31, 2014, from $383 million at December 31, 2013. The decrease in nonperforming assets primarily reflected decreases in nonaccrual commercial loans ($27 million), nonaccrual residential mortgage loans ($5 million) and foreclosed property ($5 million), partially offset by an increase in nonaccrual commercial real estate loans ($7 million). Nonperforming assets as a percentage of total loans and foreclosed property was 0.76 percent at March 31, 2014, compared to 0.84 percent at December 31, 2013.

The Corporation limits risk inherent in its commercial real estate lending activities by limiting exposure to those 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 $10.6 billion at March 31, 2014, of which $3.3 billion, or 31 percent, were to borrowers in the Commercial Real Estate business line, which includes loans to real estate developers. The remaining $7.3 billion, or 69 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 totaled $1.8 billion at March 31, 2014. The real estate construction loan portfolio primarily contains loans made to long-time customers with satisfactory completion experience. Of the $1.5 billion of real estate construction loans in the Commercial Real Estate business line, $18 million were on nonaccrual status at March 31, 2014. In other business lines, $1 million of real estate construction loans were on nonaccrual status at March 31, 2014.

The commercial mortgage loan portfolio totaled $8.8 billion at March 31, 2014 and included $1.8 billion in the Commercial Real Estate business line and $7.0 billion in other business lines. Loans in the commercial mortgage portfolio generally mature within three to five years. Of the $1.8 billion of commercial mortgage loans in the Commercial Real Estate business line, $58

million were on nonaccrual status at March 31, 2014. Commercial mortgage loan net charge-offs in the Commercial Real Estate business line were $5 million for the three months ended March 31, 2014. In other business lines, $104 million of commercial mortgage loans were on nonaccrual status at March 31, 2014, and net charge-offs were insignificant for the three months ended March 31, 2014.

The geographic distribution and project type of commercial real estate loans are important factors in diversifying credit risk within the portfolio. The following table reflects real estate construction and commercial mortgage loans to borrowers in the Commercial Real Estate business line by project type and location of property.

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, totaled $3.3 billion at March 31, 2014. Residential mortgages totaled $1.8 billion at March 31, 2014, and were primarily larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.8 billion of residential mortgage loans outstanding, $48 million were on nonaccrual status at March 31, 2014. The home equity portfolio totaled $1.5 billion at March 31, 2014, of which $1.4 billion was outstanding under primarily variable-rate, interest-only home equity lines of credit and $97 million were closed-end home equity loans. Of the $1.5 billion of home equity loans outstanding, $32 million were on nonaccrual status at March 31, 2014. A majority of the home equity portfolio was secured by junior liens at March 31, 2014. 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. Such loans are charged off to current appraised values less costs to sell no later than 180 days past due.

Shared National Credits

SNCs are defined by banking regulators as facilities of more than $20 million shared by three or more federally supervised financial institutions that are selectively reviewed on an annual basis by regulatory authorities at the agent bank level. The Corporation generally seeks to obtain ancillary business at the origination of a SNC relationship. Loans classified as SNC loans totaled $10.1 billion at March 31, 2014 (approximately 865 borrowers), compared to $9.4 billion (approximately 860 borrowers) at December 31, 2013. SNC loans are held to the same credit underwriting and pricing standards as the remainder of the loan portfolio. Comerica Bank (the Bank) was the agent for $1.5 billion of the SNC loans outstanding at both March 31, 2014 and December 31, 2013. Nonaccrual SNC loans decreased $2 million to $9 million at March 31, 2014, compared to $11 million at December 31, 2013. SNC net loan recoveries totaled $2 million for the three months ended March 31, 2014, compared to net charge-offs of $3 million for the three months ended March 31, 2013.

Energy Lending

The Corporation has a portfolio of energy-related loans that are included primarily in "commercial loans" in the consolidated balance sheets. The Corporation has over 30 years of experience in energy lending, with a focus on middle market companies. Loans in the Middle Market - Energy business line were $3.1 billion, or approximately 7 percent of total loans, at March 31, 2014, compared to $2.8 billion, or approximately 6 percent of total loans, at December 31, 2013. Nonaccrual Middle Market - Energy loans totaled $1 million at both March 31, 2014 and December 31, 2013. Middle Market - Energy net loan charge-offs were zero for both the three months ended March 31, 2014 and the three months ended December 31, 2013. Energy loans are diverse in nature, with outstanding balances by customer market segment distributed approximately as follows at March 31, 2014: 74 percent exploration and production (comprised of approximately 56 percent oil, 24 percent mixed and 20 percent natural gas), 11 percent midstream and 15 percent energy services.

State and Local Municipalities

In the normal course of business, the Corporation serves the needs of state and local municipalities in multiple capacities, including traditional banking products such as deposit services, loans and letters of credit, investment banking services such as bond underwriting and private placements, and by investing in municipal securities.

The following table summarizes the Corporation's direct exposure to state and local municipalities as of March 31, 2014 and December 31, 2013.



(in millions)	March 31, 2014		December 31, 2013
Loans outstanding	$	23	$	39

Trading account securities	1		3
Standby letters of credit	96		97
Unused commitments to extend credit	31		20
Total direct exposure to state and local municipalities	$	504	$	511

Indirect exposure comprised $104 million in auction-rate preferred securities collateralized by municipal securities at March 31, 2014, compared to $109 million at December 31, 2013. Additionally, the Corporation is exposed to Automated Clearing House (ACH) transaction risk for those municipalities utilizing this electronic payment and/or deposit method and similar products in their cash flow management. The Corporation sets limits on ACH activity during the underwriting process.

Extensions of credit to state and local municipalities are subjected to the same underwriting standards as other business loans. At both March 31, 2014 and December 31, 2013, all outstanding municipal loans and leases were performing according to contractual terms, and one municipal lease was included in the Corporation's criticized loan list. Municipal leases are secured by the underlying equipment, and a substantial majority of the leases are fully defeased with AAA-rated U.S. government securities. Substantially all municipal investment securities available-for sale are auction-rate securities. All auction-rate securities are reviewed quarterly for other-than-temporary impairment. All auction-rate municipal securities were rated investment grade, and

Table of Contents

all auction-rate preferred securities collateralized by municipal securities were rated investment grade and were adequately collateralized at both March 31, 2014 and December 31, 2013. Municipal securities are held in the trading account for resale to customers. In addition, Comerica Securities, a broker-dealer subsidiary of the Bank, underwrites bonds issued by municipalities. All bonds underwritten by Comerica Securities are sold to third party investors.

On July 18, 2013, the city of Detroit filed for Chapter 9 bankruptcy protection in federal court. The Corporation's direct exposure to the city of Detroit is insignificant.

Automotive Lending

Substantially all dealer loans are in the National Dealer Services business line. Loans in the National Dealer Services business line include floor plan financing and other loans to automotive dealerships. Floor plan loans, included in “commercial loans” in the consolidated balance sheets, totaled $3.4 billion at March 31, 2014, a decrease of $67 million compared to December 31, 2013. At March 31, 2014, other loans to automotive dealers in the National Dealer Services business line totaled $2.1 billion, including $1.4 billion of owner-occupied commercial real estate mortgage loans, compared to $2.4 billion of other loans to automotive dealers in the National Dealer Service line, including $1.4 billion of owner-occupied commercial real estate mortgage loans, at December 31, 2013. 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 approximately $1.3 billion at both March 31, 2014 and December 31, 2013.

International Exposure

International assets are subject to general risks inherent in the conduct of business in foreign countries, including economic uncertainties and each foreign government's regulations. Risk management practices minimize the risk inherent in international lending arrangements. These practices include structuring bilateral agreements or participating in bank facilities, which secure repayment from sources external to the borrower's country. Accordingly, such international outstandings are excluded from the cross-border risk of that country.

The Corporation does not hold any sovereign exposure to Europe. The Corporation's international strategy as it pertains to Europe is to focus on European companies doing business in North America, with an emphasis on the Corporation's primary geographic markets. The following table summarizes cross-border exposure to entities domiciled in European countries at March 31, 2014 and December 31, 2013.

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, and commodity 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.

The Corporation's Treasury and Enterprise Risk Departments supports ALCO in measuring, monitoring and managing interest rate, liquidity and coordination of all other market risks. Key activities encompass: (i) providing information and analysis of the Corporation's balance sheet structure and measurement of interest rate, liquidity 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 analysis and strategies to adjust risk positions; (iv) reviewing and presenting policies and authorizations for approval; (v) monitoring of industry trends and analytical tools to be used in the management of interest rate, liquidity and all other market risks; and (vi) developing and monitoring the interest rate risk economic capital estimate.

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 a combination of core deposits and wholesale borrowings. Approximately 85 percent of the Corporation's loans were floating at March 31, 2014, of which approximately 75 percent were based on LIBOR and 25 percent were based on Prime. This creates sensitivity to interest rate movements due to the imbalance between the floating-rate loan portfolio and the more slowly repricing deposit products. In addition, 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 investment securities, primarily fixed-rate, which provide liquidity to the balance sheet and act to mitigate the inherent interest sensitivity, and hedging the sensitivity with interest rate swaps. 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 and what is believed to be the most likely balance sheet structure. Existing derivative instruments entered into for risk management purposes are included in the analysis, but no additional hedging is currently forecasted. These derivative instruments currently comprise interest rate swaps that convert fixed-rate long term debt to variable rates. This base case net interest income is then compared against interest rate scenarios in which rates rise or decline in a linear, non-parallel fashion from the base case over 12 months. In the scenarios presented, short-term interest rates increase 200 basis points, resulting in an average increase in short-term interest rates of 100 basis points over the period (+200 scenario). Due to the current low level of interest rates, the analysis reflects a declining interest rate scenario of a 25 basis point drop in short-term interest rates, to zero percent.

Each interest rate scenario includes assumptions such as loan growth, investment security prepayment levels, depositor behavior, yield curves, loan and deposit pricing, and overall balance sheet mix and growth. In the + 200 scenario, assumptions related to loan growth and deposit run-off are based on historical experience, resulting in a modest increase in loans and a modest decrease in deposits from the base case. No changes are modeled to investment securities beyond the replacement of prepayments, and expected funding maturities are included. As a result of the modeled balance sheet movement, excess reserves diminish. In addition, the model reflects deposit pricing based on historical price movements with short-term interest rates. Changes in economic activity, whether domestic or international, may result in a balance sheet structure that is different from the changes management

included in its simulation analysis and may translate into a materially different interest rate environment than those presented. For example, deposit balances have grown significantly over the past several years, creating uncertainty regarding future deposit balance levels. A decline in deposit balances beyond historical experience would reduce the estimated increase in net interest income in the +200 scenario.

The table below, as of March 31, 2014 and December 31, 2013, 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
	March 31, 2014					December 31, 2013
(in millions)	Amount			%		Amount			%
Change in Interest Rates:
+200 basis points	$	213		13	%	$	210		13	%
-25 basis points (to zero percent)	(29		)	(2	)	(30		)	(2	)

Sensitivity increased slightly from December 31, 2013 to March 31, 2014 primarily due to modest changes in forecasted balance sheet mix. The risk to declining interest rates is limited as a result of the inability of the current low level of rates to fall significantly.

The table below, as of March 31, 2014, illustrates the estimated sensitivity of the above results to a change in deposit balance assumptions in the +200 scenario, with all other assumptions held constant. In this analysis, average noninterest-bearing deposit run-off in the 12-month period has been increased by $1 billion and $3 billion from the historical run-off experience included in the standard +200 scenario presented above and assumes the deposit run-off reduces excess reserves. The analysis is provided as an indicator of the sensitivity of net interest income to the modeled deposit run-off assumption. It is not meant to reflect management's expectation or best estimate. Actual run-off results may vary from those reflected. The analysis also does not capture possible regulatory impacts, including proposed liquidity requirements, which could impact pricing and deposit products offered and how interest rate risk is managed.

March 31, 2014	Amount		%
Incremental Average Decrease in Noninterest-bearing Deposit Balances:
$1 billion	$	202	12	%
$3 billion	180		11

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 economic value of equity analysis is based on an immediate parallel 200 basis point increase and 25 basis point decrease in interest rates.

The table below, as of March 31, 2014 and December 31, 2013, displays the estimated impact on the economic value of equity from the interest rate scenario described above.



	March 31, 2014					December 31, 2013
(in millions)	Amount			%		Amount			%
Change in Interest Rates:
+200 basis points	$	653		6	%	$	670		6	%
-25 basis points (to zero percent)	(180		)	(2	)	(164		)	(1	)

The change in the sensitivity of the economic value of equity to a 200 basis point parallel increase in rates between December 31, 2013 and March 31, 2014 was primarily driven by changes in market interest rates at the middle to long end of the curve, which most significantly impact the value of deposits without a stated maturity.

Wholesale Funding

The Corporation may access the purchased funds market when necessary, which includes foreign office time deposits and short-term borrowings. Capacity for incremental purchased funds at March 31, 2014 included the ability to purchase federal funds, sell securities under agreements to repurchase, as well as issue deposits to institutional investors and issue certificates of

deposit through brokers. Purchased funds totaled $629 million at March 31, 2014, compared to $602 million at December 31, 2013. At March 31, 2014, the Bank had pledged loans totaling $25 billion which provided for up to $20 billion of available collateralized borrowing with the FRB.

The Bank is a member of the Federal Home Loan Bank of Dallas, Texas (FHLB), 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 March 31, 2014, $14 billion of real estate-related loans were pledged to the FHLB as blanket collateral for current and potential future borrowings. As of March 31, 2014, the Corporation had $1.0 billion of outstanding borrowings from the FHLB maturing in May 2014.

Additionally, the Bank had the ability to issue up to $15.0 billion of debt at March 31, 2014 under an existing $15 billion medium-term senior 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 Federal Reserve completed its 2014 CCAR review in March 2014 and did not object to Comerica's capital plan and capital distributions contemplated in the plan. Comerica's capital plan includes the authority to fully redeem $150 million par value of subordinated notes due 2024. The notes are callable at par on or after July 15, 2014 and were recorded at a carrying value of $183 million at March 31, 2014.

Further information regarding the Corporation's medium- and long-term debt is provided in Note 7 to these unaudited financial statements.

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 March 31, 2014, the four major rating agencies had assigned the following ratings 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 requirements with either liquid assets or various funding sources. Liquid assets, which totaled $11.9 billion at March 31, 2014, compared to $12.6 billion at December 31, 2013, provide a reservoir of liquidity. Liquid assets include cash and due from banks, federal funds sold, interest-bearing deposits with banks, other short-term investments and unencumbered investment securities available-for-sale. At March 31, 2014, the Corporation held excess liquidity, represented by $4.3 billion deposited with the FRB, compared to $5.2 billion at December 31, 2013.

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 2013 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, 2013, the most critical of these significant accounting policies were the policies related to the allowance for credit losses, valuation methodologies, 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-41 through F-46 in the Corporation's 2013 Annual Report. As of the date of this report, the Corporation does not believe there are any material changes in the nature or categories of the critical accounting policies or estimates and assumptions from those discussed in the Corporation's 2013 Annual Report.

(b)	March 31, 2014 Tier 1 capital and risk-weighted-assets are estimated.


(c)	Estimated ratios based on the standardized approach in the final rule for the U.S. adoption of the Basel III regulatory capital framework, excluding most elements of AOCI.

The Tier 1 common capital ratio removes preferred stock and qualifying trust preferred securities from Tier 1 capital as defined by and calculated in conformity with bank regulations. The Basel III common equity Tier 1 capital ratio further adjusts Tier 1 common capital and risk-weighted assets to account for the final rule approved by U.S. banking regulators in July 2013 for the U.S. adoption of the Basel III regulatory capital framework. The final Basel III capital rules are effective January 1, 2015 for banking organizations subject to the standardized approach. The tangible common equity ratio removes preferred stock and the effect of intangible assets from capital and the effect of intangible assets from total assets and tangible common equity per share of common stock removes the effect of intangible assets from common shareholders' equity per share of common stock. The Corporation believes these measurements are meaningful measures of capital adequacy used by investors, regulators, management and others to evaluate the adequacy of common equity and to compare against other companies in the industry.
