Notes to Consolidated Financial Statements (unaudited)
Comerica Incorporated and Subsidiaries
NOTE 1 - BASIS OF PRESENTATION AND ACCOUNTING POLICIES
The accompanying unaudited consolidated financial statements were prepared in accordance with 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, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. 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, 2011.
Recently Adopted Accounting Standards
In the first quarter 2012, the Corporation adopted amendments to GAAP which revise the presentation of comprehensive income in the financial statements. As a result, the Corporation presents on an interim basis the components of net income and a total for comprehensive income in one continuous consolidated statement of comprehensive income and will present on an annual basis the components of net income and other comprehensive income in two separate, but consecutive statements. Information on the components of other comprehensive income is provided on an interim basis in Note 9 to these unaudited financial statements.
In the first quarter 2012, the Corporation adopted an amendment to GAAP which generally aligns the principles of fair value measurements with International Financial Reporting Standards (IFRSs) and requires expanded disclosures. The adoption of the amendment had no impact on the Corporation's financial condition or results of operations. The required disclosures are provided in Note 2 to these unaudited financial statements.
Pending Accounting Pronouncements
In December 2011, the Financial Accounting Standards Board issued an amendment to GAAP which requires enhanced disclosures about the nature and effect or potential effect of an entity's rights of setoff associated with its financial and derivative instruments. The Corporation will adopt the amendment in the first quarter 2013. While the amendment will expand the Corporation's financial and derivative instruments disclosures, the Corporation does not expect the adoption of the amendment to have any effect on the Corporation's financial condition and results of operations.
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.

5

Table of Contents

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

 
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 and investment securities, 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
Securities held for trading purposes 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 securities held for trading purposes 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. Securities classified as Level 3 include securities in less liquid markets and securities not rated by a credit agency. 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. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available or the market is deemed to be inactive at the measurement date, an adjustment to the quoted prices may be necessary. In some circumstances, the Corporation may conclude that a change in valuation technique or the use of multiple valuation techniques may be appropriate to estimate an instrument's fair value. 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, of which the substantial majority is auction-rate securities, represent securities in less liquid markets requiring significant management assumptions when determining fair value. 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 observed liquidity premiums based on auction-rate securities valuations performed by third parties and incorporated the rate at which the various types of similar auction-rate securities had been redeemed or sold since acquisition in 2008. 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. As of March 31, 2012, approximately 72 percent of the aggregate auction-rate securities par value had been redeemed or sold since acquisition. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. Additionally, as the discount rate incorporates the liquidity risk premium, a change in an assumption used for the liquidity risk premium would be accompanied by a directionally similar change in the discount rate. On an annual basis, an independent third party verifies the fair value by reviewing the appropriateness of the discounted cash flow model and its significant inputs.
Loans
The Corporation does not record loans at fair value on a recurring basis. However, periodically, the Corporation records nonrecurring adjustments to the carrying value of loans based on fair value measurements. Loans for which it is probable that payment of interest or principal will not be made in accordance with the contractual terms of the original loan agreement are considered impaired, which are reported as nonrecurring fair value measurements when a specific allowance for the impaired loan is established based on the fair value of collateral. 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 Corporation provides fair value estimates for loans not recorded at fair value. 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 reflect 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
The carrying amount of these instruments approximates the estimated fair value, due to their short-term nature. 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 for its over-the-counter derivative positions on a counterparty-by-counterparty basis and 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.
The Corporation holds a portfolio of warrants for generally nonmarketable equity securities. These warrants are primarily from high technology, non-public companies obtained as part of the loan origination process. 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. Significant increases in any of these inputs in isolation, with the exception of exercise price, would result in a significantly higher fair value. Significant increases in exercise price in isolation would result in a significantly 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. 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. 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 15 years. The value of these investments is at risk to changes in equity markets, general economic conditions and a variety of other factors. The investments are accounted for 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 Corporation's percentage ownership in the net asset value of the entire fund, 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. The Corporation classifies both nonmarketable equity securities subjected to nonrecurring fair value adjustments and the estimated fair value of nonmarketable equity securities not recorded at fair value in their entirety on a recurring basis as Level 3. Commitments to fund additional investments in nonmarketable equity securities recorded at fair value on a nonrecurring basis were $2 million and $1 million at March 31, 2012 and December 31, 2011, respectively.
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) 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 $92 million and its investment in FRB stock totaled $85 million at both March 31, 2012 and December 31, 2011, respectively. The Corporation believes its investments in FHLB and FRB stock are ultimately recoverable at par.
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. Throughout each quarter, the Corporation obtains updated independent market prices and appraised values as are required by state regulation or as are 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 collateral values and other current market

factors. Other real estate carried at fair value based on an observable market price or a current appraised value is classified by the Corporation as Level 2. 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.
Loan servicing rights
Loan servicing rights, included in “accrued income and other assets” on the consolidated balance sheets and primarily related to Small Business Administration loans, are subject to impairment testing. Loan servicing rights may be carried at fair value on a nonrecurring basis when impairment testing indicates that the fair value of the loan servicing rights is less than the recorded value. A valuation model is used for impairment testing on a quarterly basis, which utilizes a discounted cash flow model, using interest rates and prepayment speed assumptions currently quoted for comparable instruments and a discount rate determined by management. If the valuation model reflects a value less than the carrying value, loan servicing rights are adjusted to fair value through a valuation allowance as determined by the model. As such, the Corporation classifies loan servicing rights 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 standby and commercial 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, 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. Assets recorded at fair value on a nonrecurring basis are presented in the following table. No liabilities were recorded at fair value on a nonrecurring basis at March 31, 2012 and December 31, 2011.

Level 3 assets recorded at fair value on a nonrecurring basis at March 31, 2012 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.
ESTIMATED FAIR VALUES OF FINANCIAL INSTRUMENTS NOT RECORDED AT FAIR VALUE ON A RECURRING BASIS
The Corporation typically holds the majority of its financial instruments until maturity and thus does not expect to realize many of the estimated fair value amounts disclosed. The disclosures also do not include estimated fair value amounts for items that are not defined as financial instruments, but which have significant value. These include such items as core deposit intangibles, the future earnings potential of significant customer relationships and the value of trust operations and other fee generating businesses. The Corporation believes the imprecision of an estimate could be significant.

(a)
Residential mortgage-backed securities issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises.
(b)
Primarily auction-rate securities.
(c)
Unrealized losses less than $0.5 million.
As of March 31, 2012, 92 percent of the Corporation’s auction-rate portfolio was rated Aaa/AAA by the credit rating agencies.
At March 31, 2012, the Corporation had 158 securities in an unrealized loss position with no credit impairment, including 121 auction-rate preferred securities, 24 state and municipal auction-rate securities, 12 residential mortgage-backed securities and one auction-rate debt security. 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, 2012.
Sales, calls and write-downs of investment securities available-for-sale resulted in the following gains and losses, recorded in “net securities gains” on the consolidated statements of comprehensive income, computed based on the adjusted cost of the specific security.

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

Included in the contractual maturity distribution in the table above were auction-rate securities with a total amortized cost and fair value of $28 million and $23 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 a total amortized cost and fair value of $9.3 billion and $9.6 billion, respectively. 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, 2012, investment securities with a carrying value of $2.8 billion were pledged where permitted or required by law to secure $2.1 billion of liabilities, primarily public and other deposits of state and local government agencies and derivative instruments.

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. Included in the special mention category were $409 million and $481 million at March 31, 2012 and December 31, 2011, respectively, of loans proactively monitored by management that were considered “pass” by regulatory authorities.
(c)
Substandard loans are accruing loans that have a well-defined weakness, or weaknesses, such as loans to borrowers who may be experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. Substandard loans also are distinguished by the distinct possibility of loss in the future if these weaknesses are not corrected. 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 - Summary of Significant Accounting Policies - on page F-59 in the Corporation's 2011 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 investors and developers.
(f)
Primarily loans secured by owner-occupied real estate.

(b)

Primarily loans to real estate investors and developers.
(d)
Primarily loans secured by owner-occupied real estate.
At March 31, 2012 and December 31, 2011, commitments to lend additional funds to borrowers whose terms have been modified in TDRs totaled $11 million and $13 million, respectively.
The majority of the modifications considered to be TDRs that occurred during the three-month period ended March 31, 2012 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-month period ended March 31, 2012 were insignificant.
On an ongoing basis, the Corporation monitors the performance of modified loans to their restructured terms. 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. During the twelve-month period from April 1, 2011 to March 31, 2012, loans with a carrying value of $32 million at March 31, 2012 had been modified by reducing the rate on the loans. Of these modifications, $7 million, primarily consisting of commercial mortgage loans included in other business lines and residential mortgage loans, subsequently defaulted during the same twelve-month period. During the twelve-month period from April 1, 2011 to March 31, 2012, loans with a carrying value of $33 million at March 31, 2012 had been restructured into two notes. Of these modifications, $2 million of commercial loans subsequently defaulted during the same twelve-month period. 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-month period from April 1, 2011 to March 31, 2012, loans with a carrying value of $187 million at March 31, 2012 had been modified by principal deferral. Of these principal deferral modifications, $91 million, primarily consisting of commercial loans and commercial mortgage loans included in the

Commercial Real Estate and other business lines, subsequently experienced a change in the risk rating such that the loans are currently included in non-performing loans. 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.
Purchased Credit-Impaired (PCI) Loans
In connection with the acquisition of Sterling Bancshares, Inc. (Sterling) on July 28, 2011, the Corporation acquired loans both with and without evidence of credit quality deterioration since origination. The acquired loans were 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. The Corporation aggregated the acquired PCI loans into pools of loans based on common risk characteristics.
The carrying amount of acquired PCI loans included in the consolidated balance sheet and the related outstanding balance at March 31, 2012 and December 31, 2011 were as follows. The outstanding balance represents the total amount owed as of March 31, 2012 and December 31, 2011, including accrued but unpaid interest and any amounts previously charged off. No allowance for loan losses was required on the acquired PCI loan pools at both March 31, 2012 and December 31, 2011.

NOTE 5 - GOODWILL
The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and on an interim basis if events or changes in circumstances between annual tests indicate goodwill might be impaired.
In January 2012, the Federal Reserve announced their expectation for the Federal Funds target rate to remain at currently low levels through 2014. Given the potential for a continued low interest rate environment, the Corporation determined that an additional interim goodwill impairment test should be performed in the first quarter 2012.
At the conclusion of the first step of the interim goodwill impairment tests performed in the first quarter 2012, the estimated fair values of all reporting units exceeded their carrying amounts, including goodwill.
NOTE 6 - 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. Derivatives are carried at fair value in the consolidated financial statements. 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

25

Table of Contents

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. For derivatives 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, on a net basis, of contracts entered into with the same counterparty. 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, 2012, counterparties had pledged marketable investment securities to secure 89 percent of the fair value of contracts with bilateral collateral agreements in an unrealized gain 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, 2012 was $82 million, for which the Corporation had pledged collateral of $67 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, 2012, the Corporation would have been required to assign an additional $15 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 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.

Asset derivatives are included in “accrued income and other assets” and liability derivatives are included in “accrued expenses and other liabilities” on the consolidated balance sheets. Included in the fair value of derivative assets and liabilities are credit valuation adjustments reflecting counterparty credit risk and credit risk of the Corporation. The fair value of derivative assets included credit valuation adjustments for counterparty credit risk totaling $6 million and $4 million at March 31, 2012 and December 31, 2011, respectively.
(b)
Notional or contract 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.
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 $17 million and $18 million for the three-month periods ended March 31, 2012 and 2011, respectively.

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 (losses) on risk management derivative instruments used as economic hedges in "other noninterest income" in the consolidated statements of comprehensive income for both the three-month periods ended March 31, 2012 and 2011.

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

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, 2012 and December 31, 2011, the allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, was $25 million and $26 million, respectively. The Corporation recorded a purchase discount for lending-related commitments acquired from Sterling on July 28, 2011. An allowance for credit losses will be recorded on Sterling lending-related commitments only to the extent that the required allowance exceeds the remaining purchase discount. At both March 31, 2012 and December 31, 2011, no allowance was recorded for Sterling lending-related commitments and $3 million of purchase discount remained.
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 $8 million and $9 million at March 31, 2012 and December 31, 2011, 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 2021. 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 $292 million and $271 million, respectively, of the $5.4 billion and $5.5 billion standby and commercial letters of credit outstanding at March 31, 2012 and December 31, 2011, 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 $86 million at March 31, 2012, including $69 million in deferred fees and $17 million in the allowance for credit losses on lending-related commitments. At December 31, 2011, the comparable amounts were $89 million, $72 million and $17 million, respectively.
The following table presents a summary of internally classified watch list standby and commercial letters of credit at March 31, 2012 and December 31, 2011. The Corporation's internal watch 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, 2012 and December 31, 2011, the total notional amount of the credit risk participation agreements was approximately $439 million and $394 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 $12 million at both March 31, 2012 and December 31, 2011, 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, 2012, 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 insignificant at March 31, 2012 and $6 million at December 31, 2011, respectively.
NOTE 7 - 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 following provides a summary of the VIEs in which the Corporation has an interest.
The Corporation has a limited partnership interest in 157 low income housing tax credit/historic rehabilitation tax credit partnerships. These entities meet the definition of a VIE; however, the Corporation is not the primary beneficiary of the entities, as the general partner 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 agreements allow the limited partners, through a majority vote, to remove the general partner, this right is not deemed to be substantive as the general partner can only be removed for cause.

The Corporation accounts for its interest in these partnerships on either the cost or equity method. Exposure to loss as a result of the Corporation’s involvement with these entities at March 31, 2012 was limited to approximately $351 million, which reflected the book basis of the Corporation's investment and unfunded commitments for future investments.
As a limited partner, the Corporation obtains income tax credits and deductions from the operating losses of these low income housing tax credit/historic rehabilitation tax credit partnerships, which are recorded as a reduction of income tax expense (or an increase to income tax benefit) and a reduction of federal income taxes payable. These income tax credits and deductions are allocated to the funds’ investors based on their ownership percentages. Investment balances, including all legally binding commitments to fund future investments, are included in “accrued income and other assets” on the consolidated balance sheets, with amortization and other write-downs of investments recorded in “other noninterest income” on the consolidated statements of comprehensive income. In addition, a liability is recognized in “accrued expenses and other liabilities” on the consolidated balance sheets for all legally binding unfunded commitments to fund low income housing partnerships ($98 million at March 31, 2012).
The Corporation provided no financial or other support that was not contractually required to any of the above VIEs during the three-month periods ended March 31, 2012 and 2011.
The following table summarizes the impact of these VIEs on line items on the Corporation’s consolidated statements of comprehensive income.

At December 31, 2011, $30 million of the subordinated notes remained. On January 7, 2012, the Corporation fully redeemed $4 million of floating rate subordinated notes, and the related trust preferred securities, with an original maturity date of July 7, 2033. Further, on April 24, 2012, the Corporation announced its intention to redeem the remaining $26 million of floating rate subordinated notes, with an original maturity of June 15, 2037, and the related trust preferred securities, effective June 15, 2012.
Comerica Bank (the Bank), a subsidiary of the Corporation, is a member of the FHLB, which provides short- and long-term funding collateralized by mortgage-related assets to its members. FHLB advances bear interest at variable rates based on LIBOR and were secured by a blanket lien on $15 billion of real estate-related loans at March 31, 2012.

NOTE 12 - INCOME TAXES AND TAX-RELATED ITEMS
The provision for federal income taxes is computed by applying the statutory federal income tax rate to income before income taxes as reported in the consolidated financial statements after deducting non-taxable items, principally income on bank-owned life insurance, and deducting tax credits related to investments in low income housing partnerships. Tax-related interest and penalties, state taxes and foreign taxes are then added to the federal tax provision.
At March 31, 2012, net unrecognized tax benefits were $21 million, compared to $9 million at March 31, 2011. The increase in unrecognized tax benefits of $12 million from March 31, 2011 to March 31, 2012 was primarily the result of the recognition of a settlement agreement with the Internal Revenue Service (IRS) regarding the repatriation of foreign earnings on a structured investment transaction and the recognition of other federal and state settlements. The Corporation anticipates that it is reasonably possible that final settlement of federal and state tax issues will result in a decrease of net unrecognized tax benefits of $21 million within the next twelve months. At March 31, 2012, the Corporation had no investment structures with uncertain tax positions. Included in "accrued expense and other liabilities" on the consolidated balance sheets was a $7 million receivable for tax-related interest at March 31, 2012 compared to a $7 million liability for tax-related interest and penalties at March 31, 2011. The $14 million decrease in accrued interest payable from March 31, 2011 to March 31, 2012 was primarily the result of the aforementioned settlements with tax authorities.
In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service 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 13 - CONTINGENT LIABILITIES
Legal Proceedings
The Corporation and certain of its subsidiaries are subject to various 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 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 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. Litigation-related expense of $11 million and $1 million and legal fees of $9 million each period were included in “other noninterest expenses” on the consolidated statements of comprehensive income for the three-month periods ended March 31, 2012 and 2011, respectively. 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. However, in the event of significant unexpected future developments on existing cases, it is possible that the ultimate resolution of these matters, if unfavorable, may be material to the

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

Corporation's consolidated financial condition, consolidated results of operations or consolidated cash flows.
For other matters, where a loss is not probable, the Corporation has not established legal reserves. In determining whether it is possible to provide an estimate of loss or range of possible loss, the Corporation reviews and evaluates its material litigation on an ongoing basis, in conjunction with legal counsel, in light of potentially relevant factual and legal developments. Based on current knowledge, expectation of future earnings, and after consultation with legal counsel, management believes the maximum amount of reasonably possible losses would not have a material adverse effect on the Corporation's consolidated financial condition, consolidated results of operations or consolidated cash flows. However, 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.
 The damages alleged by plaintiffs or claimants may be overstated, unsubstantiated by legal theory, unsupported by the facts, and/or bear no relation to the ultimate award that a court, jury or agency might impose. In view of the inherent difficulty of predicting the outcome of such matters, the Corporation cannot state with confidence a range of reasonably possible losses, nor what the eventual outcome of these matters will be. However, based on current knowledge and after consultation with legal counsel, management believes the maximum amount of reasonably possible losses would not have a material adverse effect on the Corporation’s consolidated financial condition, consolidated results of operations or consolidated cash flows.
For information regarding income tax contingencies, refer to Note 12.
NOTE 14 - 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 in 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. For comparability purposes, amounts in all periods are based on business segments and methodologies in effect at March 31, 2012. These methodologies may be modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product lines.
For a description of the business activities of each business segment and further information on the methodologies, which form the basis for these results, refer to Note 23 to the consolidated financial statements in the Corporation's 2011 Annual Report.
Business segment financial results are as follows:

NOTE 15 – MERGER AND RESTRUCTURING CHARGES
The Corporation committed to a restructuring plan in connection with the completion of the acquisition of Sterling on July 28, 2011. The restructuring plan, which is expected to be substantially completed by December 31, 2012, is intended to streamline operations across the combined organization. The restructuring plan is expected to result in cumulative costs of approximately $115 million ($73 million, after-tax) through the end of the plan, primarily encompassing facilities and contract termination charges, systems integration and related charges, severance and other employee-related charges, and transaction-related costs. The Corporation recognized acquisition-related expenses of $75 million ($47 million after-tax) from July 28, 2011 (the acquisition date) to March 31, 2012, recorded in “merger and restructuring charges” in the consolidated statements of comprehensive income. Merger and restructuring charges include the incremental costs to integrate the operations of Sterling and do not reflect

Should one or more of these risks materialize or should underlying beliefs or assumptions prove incorrect, Comerica's actual results could differ materially from those discussed. Factors that could cause or contribute to such differences are changes in general economic, political or industry conditions; changes in monetary and fiscal policies, including the interest rate policies of the Federal Reserve Board; volatility and disruptions in global capital and credit markets; changes in the Corporation's credit rating; the interdependence of financial service companies; changes in regulation or oversight; unfavorable developments concerning credit quality; the acquisition of Sterling Bancshares, Inc., or any future acquisitions; the effects of more stringent capital or liquidity requirements; declines or other changes in the businesses or industries of the Corporation's customers; the implementation of the Corporation's strategies and business models, including the implementation of revenue enhancements and efficiency improvements; the Corporation's ability to utilize technology to efficiently and effectively develop, market and deliver new products and services; operational difficulties, failure of technology infrastructure or information security incidents; changes in the financial markets, including fluctuations in interest rates and their impact on deposit pricing; competitive product and pricing pressures among financial institutions within the Corporation's markets; changes in customer behavior; management's ability to maintain and expand customer relationships; management's ability to retain key officers and employees; the impact of legal and regulatory proceedings; the effectiveness of methods of reducing risk exposures; the effects of terrorist activities and other hostilities; the effects of catastrophic events including, but not limited to, hurricanes, tornadoes, earthquakes, fires, droughts and floods; changes in accounting standards and the critical nature of the Corporation's accounting policies. The Corporation cautions that the foregoing list of factors is not exclusive. For discussion of factors that may cause actual results to differ from expectations, please refer to our filings with the Securities and Exchange Commission. In particular, please refer to “Item 1A. Risk Factors” beginning on page 12 of the Corporation's Annual Report on Form 10-K for the year ended December 31, 2011. Forward-looking statements speak only as of the date they are made. The Corporation does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward-looking statements are made. For any forward-looking statements made in this news release or in any documents, the Corporation claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Results of Operations
Net income for the three months ended March 31, 2012 was $130 million, an increase of $27 million from $103 million reported for the three months ended March 31, 2011. The increase in net income in the first quarter 2012, compared to the same period in 2011, was primarily due to a $48 million increase in net interest income and a $26 million decrease in the provision for loan losses, partially offset by a $23 million increase in salaries and employee benefits expense. Net income per diluted common share was $0.66 in the first quarter 2012, compared to $0.57 for the same period one year ago. Results for the three-month period ended March 31, 2012 include the impact of operations of the former Sterling Bancshares, Inc. (Sterling), acquired by the Corporation on July 28, 2011.
Full-year 2012 Outlook
For full-year 2012, management expects the following, compared to full-year 2011, assuming a continuation of the current economic environment. For purposes of this outlook, management defines "moderate" as two percent to five percent.
Average loans increasing moderately.
Net interest income increasing moderately.
Net credit-related charge-offs and provision for credit losses declining.
Noninterest income relatively stable.
Noninterest expenses relatively stable.
Effective tax rate of approximately 27 percent.

Net interest income was $443 million for the three months ended March 31, 2012, an increase of $48 million compared to $395 million for the same period in 2011. The increase in net interest income in the first quarter 2012, compared to the same period in 2011, resulted primarily from an increase in average earning assets, accretion of the purchase discount on the acquired Sterling loan portfolio, one additional day in first quarter 2012, lower deposit rates and the continued shift in funding sources toward lower-cost funds, partially offset by decreased yields on loans and mortgage-backed investment securities. The lower loan yields reflected a shift in the average loan portfolio mix, largely due to a decrease in average commercial real estate loans and an increase in average commercial loans. The "Quarterly Analysis of Net Interest Income & Rate/Volume - Fully Taxable Equivalent" table of this financial review details the components of the change in net interest income on a fully taxable equivalent (FTE) basis for the three months ended March 31, 2012, compared to the same period in the prior year. Average earning assets increased $6.8 billion, or 14 percent, to $56.2 billion in the first quarter 2012, compared to $49.3 billion in the first quarter 2011, primarily due to the acquisition of Sterling and reflecting increases of $2.7 billion in average loans, $2.6 billion in average investment securities available-for-sale and $1.5 billion in average interest-bearing deposits with banks. The net interest margin (FTE) for the three months ended March 31, 2012 decreased 6 basis points to 3.19 percent, from 3.25 percent for the comparable period in 2011, primarily from decreased yields on loans and mortgage-backed investment securities and the impact of higher excess liquidity levels from deposit growth, partially offset by the benefit from accretion of the purchase discount on the Sterling acquired loan portfolio and lower deposit costs. Accretion of the purchase discount on the acquired Sterling loan portfolio of $25 million increased the net interest margin by 18 basis points in the first quarter 2012, and excess liquidity reduced the net interest margin by approximately 21 basis points and 14 basis points in the first quarters of 2012 and 2011, respectively. At March 31, 2012, $76 million of purchase discounts remained on acquired loans not deemed credit impaired at acquisition. Excess liquidity was represented by $3.8 billion and $2.3 billion of average balances deposited with the Federal Reserve Bank (FRB) in the first quarters of 2012 and 2011, respectively, included in “interest-bearing deposits with banks” on the consolidated balance sheets.

Provision for Credit Losses
The provision for credit losses includes both the provision for loan losses and the provision for credit losses on lending-related commitments. The Corporation performs a detailed credit quality review quarterly to determine the appropriateness of the allowance for loan losses and the allowance for credit losses on lending-related commitments and records provisions for each based on the results. For further discussion of both allowances, refer to the "Credit Risk" subheading in the "Risk Management" section of this financial review.
The provision for loan losses was $23 million for the first quarter 2012, compared to $49 million for the same period in 2011. The decrease of $26 million in the provision for loan losses in the three-month period ended March 31, 2012, when compared to the same period in 2011, resulted primarily from continued improvements in credit quality. Improvements in credit quality included a decline of $960 million, to $4.2 billion, in the Corporation's internal watch list loans from March 31, 2011 to March 31, 2012. The Corporation's internal watch list is generally consistent with loans in the Special Mention, Substandard and Doubtful categories defined by regulatory authorities. Additional indicators of improved credit quality included a decrease of $80 million in the inflow to nonaccrual loans (based on an analysis of nonaccrual loans with book balances greater than $2 million) and a decrease in net credit-related charge-offs of $56 million in the three-month period ended March 31, 2012, compared to the same period in the prior year.
Net loan charge-offs for the first quarter 2012 decreased $56 million to $45 million, or 0.43 percent of average total loans, compared to $101 million, or 1.03 percent, for the first quarter 2011. The $56 million decrease in net loan charge-offs for the first quarter 2012, compared to the first quarter 2011, primarily reflected a decrease of $50 million in Middle Market. By geographic market, net loan charge-offs decreased in all markets for the first quarter 2012, compared to the first quarter 2011.
The provision for credit losses on lending-related commitments, a component of other noninterest expenses on the consolidated statements of comprehensive income, increased $2 million to a benefit of $1 million for the three months ended March 31, 2012, compared to a benefit of $3 million for the same period in the prior year. The Corporation establishes this provision to maintain an appropriate allowance to cover probable credit losses inherent in lending-related commitments, which is discussed under the "Credit Risk" subheading in the "Risk Management" section of this financial review. The Corporation recorded a purchase discount for lending-related commitments acquired from Sterling. A provision for credit losses will not be recorded on Sterling lending-related commitments until the required allowance exceeds the remaining purchase discount. No provision was recorded for Sterling lending-related commitments during the first quarter 2012. Lending-related commitment charge-offs were insignificant in the three month periods ended March 31, 2012 and 2011.
The U.S. economy showed increasing momentum through the second half of 2011 and into the first quarter 2012. Real gross domestic product (GDP) for the fourth quarter 2011 grew at a 3.0 percent annualized rate. The Corporation expects real GDP growth in the first half of 2012 to be positive, but slow-to-moderate, indicative of an economy still hampered by lingering aftereffects of the recession of 2008-2009. The ISM Manufacturing and Non-Manufacturing Indexes for March both indicate ongoing expansion for those two broad sectors of the economy. U.S. automotive sales for March registered a 14.3 million unit annual rate and are expected to total 14.9 million units for all of 2012. The unemployment rate has declined to 8.2 percent as of March 2012. However, March 2012 payroll job growth of 120,000 was below expectations. Interest rates remain historically low. Inflation in early 2012 notched up on a month-to-month basis as petroleum prices increased. However, year-to-year comparisons of price levels trended down in early 2012. Gasoline prices climbed through the first quarter 2012 but appear to be peaking early in the second quarter 2012. Recession in the Eurozone and slower economic growth in Asia are key risk factors for the U.S.

economy in 2012, as is the threat of rapidly climbing oil prices in the aftermath of military conflict in the Middle East. Momentum in the Texas economy increased in early 2012. Labor market conditions have improved, the energy sector remains very active, and residential construction activity is picking up. Risks to the Texas economy include possible cuts in defense spending and consolidation in the airlines industry. The economy of California remains hindered by a depressed housing market. Some parts of the California economy are vibrant, notably the high tech industries of Silicon Valley. The state's large government sector remains challenged by weaker than expected tax revenues. California's economy may also be further challenged by cuts to defense spending. Michigan's economy is being buoyed by a rebounding U.S. automotive industry. Gains in durable goods manufacturing are broadening and supporting improvement to other manufacturing and to the service sector. However, many areas of the state remain hampered following the restructuring of the domestic automotive industry.
An analysis of the allowance for credit losses and nonperforming assets is presented under the "Credit Risk" subheading in the "Risk Management" section of this financial review.
Noninterest Income
Noninterest income was $206 million for the three months ended March 31, 2012, a decrease of $1 million compared to $207 million for the same period in 2011. Service charges on deposit accounts increased $4 million, in part from the acquisition of Sterling. Commercial lending fees increased $4 million, due to an increase in syndication agent fees, reflecting a higher volume of activity in the first three months of 2012, compared to the same period in the prior year. Net securities gains increased $3 million, primarily from an increase in gains from redemptions of auction-rate securities. Card fees decreased $4 million in the three-month period ended March 31, 2012, compared to the same period in the prior year, reflecting the impact of regulatory limits on debit card transaction processing fees implemented in the fourth quarter 2011. Net income from principal investing and warrants decreased $4 million and risk management hedge gains decreased $2 million in the three-month period ended March 31, 2012, compared to the same period in the prior year, primarily due to one-time gains recognized in the first quarter 2011.
Noninterest Expenses
Noninterest expenses were $448 million for the three months ended March 31, 2012, an increase of $33 million, or 8 percent, from $415 million for the comparable period in 2011. Salaries expense increased $13 million, primarily due to the acquisition of Sterling. Employee benefits expense increased $10 million, primarily reflecting increased pension expense and the addition of Sterling. Litigation-related expenses, included in other noninterest expenses on the consolidated statements of comprehensive income, increased $10 million in the three-month period ended March 31, 2012, compared to the same period in the prior year, primarily as a result of developments on certain litigation claims during the first quarter 2012. FDIC insurance expense decreased $5 million in the three-month period ended March 31, 2012, compared to the same period in 2011, primarily due to the implementation of changes to the deposit insurance assessment system effective April 1, 2011. Other real estate expense decreased $4 million in the three months ended March 31, 2012, compared to the same period in the prior year, primarily reflecting a decrease in write-downs on foreclosed property.
Provision for Income Taxes
The provision for income taxes for the three months ended March 31, 2012 was $48 million, compared to $35 million for the same period in 2011. The $13 million increase in the provision for income taxes in the three-month period ended March 31, 2012, compared to the same period in 2011, was due primarily to an increase in income before income taxes during the same period.
Net deferred tax assets were $356 million at March 31, 2012, compared to $395 million at December 31, 2011, a decrease of $39 million, primarily due to a decrease in deferred tax assets due to the utilization of tax credits, accretion of the purchase discount on the acquired Sterling loan portfolio and an increase in unrealized gains 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, 2012 and December 31, 2011. 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.

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, the Finance Division is also reported as a segment. The Other category includes items not directly associated with these business segments or the Finance Division. The performance of the business segments in 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 14 to these unaudited consolidated financial statements presents financial results of these business segments for the three months ended March 31, 2012 and 2011. For a description of the business activities of each business segment and the methodologies which form the basis for these results, refer to Note 14 to these unaudited financial statements and Note 23 to the consolidated financial statements in the Corporation's 2011 Annual Report.
The following table presents net income (loss) by business segment.

The Business Bank's net income of $206 million increased $39 million for the three months ended March 31, 2012, compared to three months ended March 31, 2011. Net interest income (FTE) of $379 million increased $38 million in the three months ended March 31, 2012, compared to the same period in the prior year, primarily due to the benefit provided by an increase of $2.6 billion in average loans, accretion of the purchase discount on the acquired Sterling loan portfolio of $16 million in the three months ended March 31, 2012, an increase in net funds transfer pricing (FTP) funding credits, primarily due to the benefit provided by an increase of $3.9 billion in average deposits, one more day in 2012 and lower deposit rates, partially offset by lower loan yields. The provision for loan losses of $1 million decreased $17 million from the comparable period in the prior year, primarily reflecting a decrease in Middle Market, partially offset by increases in Commercial Real Estate and National Dealer Services. Net credit-related charge-offs of $28 million decreased $45 million from the comparable period in the prior year, primarily due to a decrease in net charge-offs in Middle Market. Noninterest income of $81 million increased $4 million from the comparable period in the prior year, primarily due to a $5 million increase in syndication agent fees. Noninterest expenses of $159 million decreased $1 million from the same period in the prior year, primarily due to a $4 million decrease in other real estate expense, partially offset by smaller increases in several other noninterest expense categories. The provision for income taxes (FTE) of $94 million for the three months ended March 31, 2012 increased $21 million, compared to the same period in the prior year, primarily due to an increase in income before income taxes.
Net income for the Retail Bank was $14 million for the three months ended March 31, 2012, compared to a net loss of $2 million for the three months ended March 31, 2011. Net interest income (FTE) of $167 million increased $28 million in the three months ended March 31, 2012 compared to the same period in the prior year, primarily due to an increase of $356 million in average loans, an increase in net FTP funding credits, primarily due to the benefit provided by an increase of $3.0 billion in average deposits, accretion of the purchase discount on the acquired Sterling loan portfolio of $9 million in the three months ended March 31, 2012, and lower deposit rates. The provision for loan losses of $4 million decreased $19 million from the comparable period in the prior year, primarily reflecting decreases in Small Business Banking and Personal Banking. Net credit-related charge-offs of $12 million decreased $11 million from the comparable period in the prior year, with broad-based decreases across all major markets and business lines. Noninterest income of $42 million was unchanged from the comparable period in the prior year, as smaller increases in several other noninterest income categories were offset by a $5 million decrease in card fees. Noninterest expenses of $184 million increased $22 million from the comparable period in the prior year, primarily due to increases in salaries and benefit expense ($9 million), processing charges ($4 million) and allocated net corporate overhead expenses ($3 million). The increase in salaries and benefit expense was primarily due to the addition of Sterling. The provision for income taxes (FTE) of $7 million for the three months ended March 31, 2012 increased $9 million, compared to the same period in the prior year, primarily due to an increase in income before income taxes.
Wealth Management's net income of $11 million decreased $3 million for the three months ended March 31, 2012,

compared to the three months ended March 31, 2011. Net interest income (FTE) of $47 million increased $3 million in the three months ended March 31, 2012 compared to the same period in the prior year, primarily due to an increase in FTP funding credits, primarily due to the benefit provided by an $811 million increase in average deposits, and a decrease in FTP funding costs, partially offset by lower loan yields and the impact of a $242 million decrease in average loan balances. The provision for loan losses of $14 million increased $6 million from the comparable period in the prior year, primarily reflecting increases in the Florida and Midwest markets. Net credit-related charge-offs of $5 million were unchanged from the comparable period in the prior year. Noninterest income of $65 million increased $1 million from the comparable period in the prior year. Noninterest expenses of $81 million increased $3 million from the comparable period in the prior year, primarily due to a $2 million increase in salaries and employee benefits expense. The provision for income taxes (FTE) of $6 million for the three months ended March 31, 2012 decreased $2 million, compared to the same period in the prior year, primarily due to a decrease in income before income taxes.
The net loss in the Finance Division was $92 million for the three months ended March 31, 2012, compared to a net loss of $75 million in the three months ended March 31, 2011. Net interest expense (FTE) of $156 million increased $21 million in the three months ended March 31, 2012, compared to the same period in the prior year, primarily as a result of the Corporation's internal FTP methodology as described on page F-13 of the Corporation's 2011 Annual Report. The Finance Division pays the three major business segments for the long-term value of deposits based on their assumed lives. The three major business segments pay the Finance Division for funding based on the pricing and term characteristics of their loans. The increase in net interest expense (FTE) was primarily due to an increase in average deposits in the three major business segments, partially offset by an increase in average loans in the three major business segments and an an increase in average investment securities available-for-sale in the Finance Division. Noninterest income of $13 million decreased $5 million from the comparable period in the prior year, primarily due to decreases in customer derivative income and risk management hedge income. Noninterest expenses of $3 million decreased $1 million from the comparable period in the prior year. The benefit for income taxes (FTE) of $54 million for the three months ended March 31, 2012 increased $10 million, compared to the same period in the prior year, primarily resulting from an increase in losses before income taxes.
The net loss in the Other category of $9 million for the three months ended March 31, 2011 increased $8 million from the comparable period in the prior year. The increase in net loss primarily reflected an $8 million increase in noninterest expenses, primarily due to an increase in litigation and legal expenses.

The Midwest market's net income of $68 million increased $15 million for the three months ended March 31, 2012, compared to the three months ended March 31, 2011. Net interest income (FTE) of $198 million decreased $5 million from the comparable period in the prior year, primarily due to a decrease in loan yields, the impact of a $275 million decrease in average loans and an increase in net FTP funding costs, partially offset by the benefit provided by a $1.2 billion increase in average deposits, lower deposit rates and the benefit of one more day in 2012. The provision for loan losses of $10 million decreased $24 million from the comparable prior year period, primarily reflecting decreases in Middle Market, Commercial Real Estate, Small Business Banking and Personal Banking. Net credit-related charge-offs decreased $28 million from the comparable period in the prior year, primarily due to a decrease in Middle Market.

Financial Condition
Total assets were $62.6 billion at March 31, 2012, an increase of $1.6 billion from $61.0 billion at December 31, 2011, reflecting increases of $392 million in interest-bearing deposits with banks, $333 million in total loans and $843 million in accrued income and other assets. The increase in accrued income and other assets primarily reflected a receivable for the pending settlement of a large customer-initiated sweep transaction that cleared on the first business day in April 2012. On an average basis, total assets increased $568 million to $61.6 billion in the first quarter 2012, compared to the fourth quarter 2011, resulting primarily from increases in average loans ($815 million) and investment securities available-for-sale ($108 million), partially offset by a decrease in average interest-bearing deposits with banks ($409 million).

Average loans increased $815 million, or 2 percent, to $42.3 billion at March 31, 2012, compared to December 31, 2011, primarily reflecting an increase of $1.2 billion, or 5 percent, in commercial loans, partially offset by a decrease of $352 million, or 3 percent, in commercial real estate loans (commercial mortgage and real estate construction loans). The increase in average loans reflected increases in National Dealer Services ($407 million), Energy ($359 million), Global Corporate Banking ($254 million), Middle Market ($127 million) and Technology and Life Sciences ($126 million), partially offset by a decrease in Commercial Real Estate ($211 million). Average loans in the Commercial Real Estate business line continued to decline, primarily reflecting ongoing payment activity. Changes in average loans by geographic market are displayed in the table above.
Total liabilities increased $1.5 billion to $55.6 billion at March 31, 2012, compared to December 31, 2011, due to a $1.5 billion increase in total deposits. On an average basis, total liabilities increased $576 million in the first quarter 2012, compared to the fourth quarter 2011, primarily due to a $532 million increase in average deposits. The increases in average deposits from the fourth quarter 2011 to the first quarter 2012 resulted primarily from an increase in average noninterest-bearing deposits of $461 million and primarily reflected increases in Global Corporate Banking ($296 million), the Financial Services Division ($285 million), Technology and Life Sciences ($262 million) and Private Banking ($208 million), partially offset by decreases in Small Business Banking ($301 million) and Energy ($179 million). By geographic market, the increase in average deposits from the fourth quarter 2011 to the first quarter 2012 primarily reflected increases in the Midwest ($339 million), Western ($227 million) and Other ($214 million) markets, partially offset by a $105 million decrease in the Texas market.

The Federal Reserve completed its review of the Corporation's 2012 Capital Plan in March 2012 and did not object to the capital distributions contemplated in the plan. The capital plan provides for up to $375 million in equity repurchases for the five-quarter period ending March 31, 2013. The capital plan, which was approved by the Corporation's Board of Directors, further contemplated a 50 percent increase in Comerica's quarterly dividend, from 10 cents per share to 15 cents per share. The dividend proposal was approved by the Board on April 24, 2012. In addition, the capital plan included the authority to redeem the remaining $25 million of trust preferred securities outstanding as of March 31, 2012. On April 24, 2012, the Corporation provided notice to the trustee of its intent to redeem these securities effective June 15, 2012.
In November 2010, the Board of Directors of the Corporation authorized the repurchase of up to 12.6 million shares of Comerica Incorporated outstanding common stock and authorized the purchase of up to all 11.5 million of the Corporation's original outstanding warrants. On April 24, 2012, the Board authorized the repurchase of an additional 5.7 million shares of Comerica Incorporated outstanding common stock. There is no expiration date for the Corporation's share repurchase program. For further information regarding the repurchase program, refer to Note 14 to the consolidated financial statements in the Corporation's 2011 Annual Report. The following table summarizes the Corporation's repurchase activity during the three months ended March 31, 2012.

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. As shown in the table below, the Tier 1 common capital, Tier 1 risk-based capital, total risk-based capital and tangible common equity ratios decreased from December 31, 2011 to March 31, 2012, while the leverage ratio increased in the same period. The risk-based ratios decreased, while the leverage ratio increased, because the denominator for the risk-based ratios, period-end risk-weighted assets, increased more relative to the increase in capital than the denominator for the leverage ratio, adjusted quarterly average assets.

March 31, 2012 capital and ratios are estimated.
In December 2010, the Basel Committee on Banking Supervision (the Basel Committee) issued a framework for strengthening international capital and liquidity regulation (Basel III). The Basel III capital framework includes higher global minimum capital standards, including a more stringent definition of capital, new capital conservation buffers and a minimum Tier 1 common capital ratio. The Basel III capital framework also proposes the deduction of certain assets from capital, including deferred tax assets and mortgage servicing rights, among others and within prescribed limitations, as well as the inclusion of other comprehensive income in capital and increased capital requirements for counterparty credit risk. Rules are expected to be implemented between 2013 and 2019. Adoption in the U.S. is expected to occur over a similar timeframe, but the final form of the U.S. rules is not yet known.
The Basel III liquidity framework includes two minimum liquidity measures. The Liquidity Coverage Ratio requires a financial institution to hold a buffer of high-quality, liquid assets to fully cover net cash outflows under a 30-day systematic liquidity stress scenario. The Net Stable Funding Ratio 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 Corporation's liquidity position is strong, but if subject to the Basel III liquidity framework as currently proposed, the Corporation may decide to consider additional liquidity management initiatives. While uncertainty exists in both the final form of the Basel III guidance and whether or not the Corporation will be required to adopt the guidelines, the Corporation is closely monitoring the development of the guidance. We expect to meet the final requirements adopted by U.S. banking regulators within regulatory timelines.
Risk Management
The following updated information should be read in conjunction with the "Risk Management" section on pages F-23 through F-42 in the Corporation's 2011 Annual Report.
Credit Risk
Allowance for Credit Losses and Nonperforming Assets
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. In the first quarter 2012, the Corporation implemented enhancements to the methodology used for determining the allowance for loan losses for business loans. The enhancements included expanding the historical borrower rating migration and loss experience periods and estimating probability of default and loss given default from a national perspective, in addition to a market-by-market basis.
The allowance for loan losses was $704 million at March 31, 2012, compared to $726 million at December 31, 2011, a decrease of $22 million, or 3 percent. The decrease resulted primarily from improvements in credit quality, partially offset by increased loan volumes and an increase in the allowance for loan losses resulting from the methodology enhancements described above. Improvements in credit quality included a decline of $261 million in the Corporation's internal watch list loans from December 31, 2011 to March 31, 2012, a decrease in the inflow to nonaccrual (based on an analysis of nonaccrual loans with balances greater than $2 million) of $30 million and a decrease in net credit-related charge-offs of $15 million for the three months

Table of Contents

ended December 31, 2011 compared to the three months ended March 31, 2012. The $22 million decrease in the allowance for loan losses primarily reflected decreases in Commercial Real Estate and Middle Market, partially offset by an increase in Private Banking. The allowance for loan losses as a percentage of total period-end loans was 1.64 percent at March 31, 2012, compared to 1.70 percent at December 31, 2011. Nonperforming loans of $856 million at March 31, 2012 decreased $31 million, compared to December 31, 2011. Loan charge-offs are taken as amounts are determined to be uncollectible. A measure of the level of charge-offs already taken on nonaccrual loans is the current book balance as a percentage of the contractual amount owed. At both March 31, 2012 and December 31, 2011, nonaccrual loans were charged-off to approximately 60 percent of the contractual amount. This level of write-downs is consistent with losses experienced on loan defaults in the first three months of 2012 and in recent years. The allowance as a percentage of total nonperforming loans, a ratio which results from the actions noted above, was 82 percent at both March 31, 2012 and December 31, 2011. The Corporation's loan portfolio is primarily composed of business loans, which, in the event of default, are typically carried on the books at fair value as nonperforming assets for a longer period of time than are consumer loans, which are generally fully charged off when they become nonperforming, resulting in a lower nonperforming loan allowance coverage when compared to banking organizations with higher concentrations of consumer loans.
Loans acquired from Sterling 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. At both March 31, 2012 and December 31, 2011, no allowance was required for acquired loans not deemed credit-impaired and $76 million and $96 million of purchase discounts remained, respectively. Purchased credit impaired (PCI) loans are not considered nonperforming loans.
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. 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.
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 $25 million at March 31, 2012, a decrease of $1 million from $26 million at December 31, 2011. The Corporation recorded a purchase discount for lending-related commitments acquired from Sterling. An allowance for credit losses will be recorded on Sterling lending-related commitments only to the extent that the required allowance exceeds the remaining purchase discount. At both March 31, 2012 and December 31, 2011, no allowance was recorded for Sterling lending-related commitments and $3 million of purchase discount remained.

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 real estate which has been acquired through foreclosure and is awaiting disposition (foreclosed property). Nonperforming assets do not include PCI loans. Nonperforming assets decreased $58 million to $923 million at March 31, 2012, from $981 million at December 31, 2011.

Based on an analysis of nonaccrual loans with book balances greater than $2 million.
(b)
Consumer, excluding residential mortgage and certain personal purpose nonaccrual loans and net charge-offs, are included in the “Other” category.
Business loans are generally placed on nonaccrual status when management determines that full collection of principal or interest is unlikely or when principal or interest payments are 90 days past due, unless the loan is fully collateralized and in the process of collection. The primary driver of when the principal amount of a business loan should be fully or partially charged off is based on a qualitative assessment of the recoverability of the principal amount from collateral and other cash flow sources. Residential mortgage and home equity loans are generally placed on nonaccrual status and charged off to current appraised values, less costs to sell, during the foreclosure process, normally no later than 180 days past due. Other consumer loans are generally not placed on nonaccrual status and are charged off at no later than 120 days past due, earlier if deemed uncollectible. Loan amounts in excess of probable future cash collections are charged off to an amount that management ultimately expects to collect. At the time a loan is placed on nonaccrual status, interest previously accrued but not collected is charged against current income. Income on such loans is then recognized only to the extent that cash is received and the future collection of principal is probable. Generally, a loan may be returned to accrual status when all delinquent principal and interest have been received and the Corporation expects repayment of the remaining contractual principal and interest, generally based on a period of sustained payment performance, normally at least six months, or when the loan is both well secured and in the process of collection. Refer to Note 1 to the consolidated financial statements in the Corporation's 2011 Annual Report for further information regarding impaired loans.
At March 31, 2012, TDRs totaled $346 million, of which $235 million were nonperforming ($209 million nonaccrual TDRs and $26 million reduced-rate TDRs) and $111 million were considered performing. Performing TDRs included $60 million of commercial loans (primarily in Middle Market, Global Corporate Banking and Private Banking) and $51 million of commercial mortgage loans (primarily in Commercial Real Estate, Middle Market, National Dealer Services and Private Banking) at March 31, 2012. At December 31, 2011, TDRs totaled $331 million, including $206 million nonaccrual TDRs, $27 million reduced-rate TDRs and $98 million TDRs considered performing. The $15 million increase in total TDRs primarily reflected increases in Global Corporate Banking and Private Banking.

The following table presents a summary of total internal watch list loans at March 31, 2012 and December 31, 2011. Watch list loans that meet certain criteria are individually subjected to quarterly credit quality reviews, and the Corporation may establish specific allowances for such loans. The $261 million decrease in total watch list loans, compared to December 31, 2011, is reflected in the decrease in the allowance for loan losses in the same period.

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 $11.5 billion at March 31, 2012, of which $3.6 billion, or 31 percent, were to borrowers in the Commercial Real Estate business line, which includes loans to residential real estate investors and developers. The remaining $7.9 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 $1.4 billion at March 31, 2012. The real estate construction loan portfolio primarily contains loans made to long-time customers with satisfactory completion experience. However, the significant and prolonged decline in residential real estate activity that began in late 2008 in the Western, Florida and Midwest markets proved extremely difficult for many of the smaller residential real estate developers. Of the $1.1 billion of real estate construction loans in the Commercial Real Estate business line, $77 million were on nonaccrual status at March 31, 2012. Real estate construction loan net charge-offs in the Commercial Real Estate business line totaled $1 million for the three months ended March 31, 2012.
The commercial mortgage loan portfolio totaled $10.1 billion at March 31, 2012 and included $2.5 billion in the Commercial Real Estate business line and $7.6 billion in other business lines. Loans in the commercial mortgage portfolio generally mature within three to five years. Of the $2.5 billion of commercial mortgage loans in the Commercial Real Estate business line, $174 million were on nonaccrual status at March 31, 2012. Commercial mortgage loan net charge-offs in the Commercial Real Estate business line totaled $12 million for the three months ended March 31, 2012.

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, totaled $3.1 billion at March 31, 2012. Residential mortgages totaled $1.5 billion at March 31, 2012, and were primarily larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.5 billion of residential mortgage loans outstanding, $69 million were on nonaccrual status at March 31, 2012. The home equity portfolio totaled $1.6

58

Table of Contents

billion at March 31, 2012, of which $1.4 billion was outstanding under primarily variable-rate, interest-only home equity lines of credit and $186 million consisted of closed-end home equity loans. Of the $1.6 billion of home equity loans outstanding, $9 million were on nonaccrual status at March 31, 2012. A majority of the home equity portfolio was secured by junior liens.
The Corporation rarely originates residential real estate loans with loan-to-value ratios above 100 percent at origination, has no sub-prime mortgage programs and does not originate payment-option adjustable-rate mortgages or other nontraditional mortgages that allow negative amortization. A significant majority of residential mortgage originations are sold in the secondary market. Since 2008, the Corporation has used a third party to originate, document and underwrite residential mortgage loans on behalf of the Corporation. Under this arrangement, the third party assumes repurchase liability for the loans it originates. The Corporation has repurchase liability exposure for residential mortgage loans originated prior to 2008, however based on historical experience, the Corporation believes such exposure, which could be triggered by underwriting discrepancies, is minimal. The residential real estate portfolio is principally located within the Corporation's primary geographic markets. The economic recession and significant declines in home values in the Western, Florida and Midwest markets following the financial market turmoil beginning in the fall of 2008 adversely impacted the residential real estate portfolio. At March 31, 2011, the Corporation estimated that, of the $8 million total residential mortgage loans past due 90 days or more and still accruing interest, approximately $1 million exceeded 90 percent of the current value of the underlying collateral, based on S&P/Case-Shiller home price indices. To account for this exposure, the Corporation factors changes in home values into estimated loss ratios for residential real estate loans, using index-based estimates by major metropolitan area, resulting in an increased allowance allocated for residential real estate loans when home values decline. Additionally, to mitigate increasing credit exposure due to depreciating home values, the Corporation periodically reviews home equity lines of credit and makes line reductions or converts outstanding balances at line maturity to closed-end, amortizing loans when necessary.
Shared National Credits
Shared National Credit (SNC) loans are facilities greater than $20 million shared by three or more federally supervised financial institutions that are reviewed annually 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 (approximately 890 borrowers at March 31, 2012) totaled $8.7 billion at March 31, 2012, compared to $8.4 billion at December 31, 2011. SNC net loan charge-offs totaled $14 million and $1 million for the three month periods ended March 31, 2012 and 2011, respectively. SNC loans, diversified by both business line and geographic market, comprised approximately 20 percent of total loans at both March 31, 2012 and December 31, 2011 SNC loans are held to the same credit underwriting standards as the remainder of the loan portfolio and face similar credit challenges.
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 $2.2 billion at March 31, 2012, an increase of $330 million compared to $1.8 billion at December 31, 2011, primarily reflecting the continued recovery from the impact of supply chain disruptions caused by the catastrophic earthquake and tsunami in Japan in March 2011, as the significant majority of the decrease in floor plan loans was concentrated in automotive franchises selling Japanese-made vehicles. At both March 31, 2012 and December 31, 2011, other loans to automotive dealers in the National Dealer Services business line totaled $1.9 billion, including $1.4 billion of owner-occupied commercial real estate mortgage loans at both March 31, 2012 and December 31, 2011. 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 $1.1 billion at March 31, 2012, compared to $931 million at December 31, 2011.
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, 2012 and December 31, 2011.

Indirect exposure comprised $232 million in auction-rate preferred securities collateralized by municipal securities at March 31, 2012, compared to $320 million at December 31, 2011. 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 March 31, 2012 and December 31, 2011, all outstanding municipal loans and leases were performing according to contractual terms and none were included in the Corporation's internal watch 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 all auction-rate preferred securities collateralized by municipal securities were rated AAA or the equivalent and were adequately collateralized at both March 31, 2012 and December 31, 2011. Municipal securities are held in the trading account for resale to customers. In addition, Comerica Securities, a broker-dealer subsidiary of Comerica Bank, underwrites bonds issued by municipalities. All bonds underwritten by Comerica Securities are sold to third party investors.
European Exposure
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 corporations doing business in North America, with an emphasis on the major geographic markets. The following table summarizes cross-border exposure to entities domiciled in European countries at March 31, 2012 and December 31, 2011.

Market and Liquidity Risk
Interest Rate Risk
Net interest income is the predominant source of revenue for the Corporation. Interest rate risk arises primarily through the Corporation's core business activities of extending loans and accepting deposits. The Corporation's balance sheet is predominantly characterized by floating-rate loans funded by a combination of core deposits and wholesale borrowings. Approximately 80 percent of the Corporation's loans were floating at March 31, 2012, of which approximately 70 percent were based on LIBOR and 30 percent were based on Prime. This creates a natural imbalance between the floating-rate loan portfolio and the more slowly repricing deposit products. The result is that growth and/or contraction in the Corporation's core businesses may lead to 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.
The Corporation frequently evaluates net interest income under various balance sheet and interest rate scenarios, looking at a 12-month time horizon, using simulation modeling analysis as its principal risk management evaluation technique. The results of this analysis provides the information needed to assess the balance sheet structure. Changes in economic activity, whether domestic or international, different from the changes management included in its simulation analysis could translate into a materially different interest rate environment than currently expected. Management evaluates a base case net interest income under an unchanged interest rate environment and what is believed to be the most likely balance sheet structure. This base case net interest income is then evaluated against non-parallel interest rate scenarios that increase and decrease 200 basis points in a linear fashion from the base case over 12 months, resulting in an average change in interest rates of 100 basis points over the period. Due to the current low level of interest rates, the analysis reflects a declining interest rate scenario of a 25 basis point drop, to zero percent. In addition, consistent with each interest rate scenario, adjustments to asset prepayment levels, yield curves, and overall balance sheet mix and growth assumptions are made. These assumptions are inherently uncertain and, as a result, the model may not precisely predict the impact of higher or lower interest rates on net interest income. Additionally, the estimated impact on net interest income over the 12-month time horizon is generally not linear relative to other time horizons. Actual results may differ from simulated results due to timing, magnitude and frequency of changes in interest rates, market conditions and management strategies, among other factors. However, the model can indicate the likely direction of change. Existing derivative instruments entered into for risk management purposes are included in the analysis, but no additional hedging is forecasted.
The table below, as of March 31, 2012 and December 31, 2011, 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. The sensitivity from December 31, 2011 to March 31, 2012 increased primarily due to growth in core deposits, though risk to declining interest rates is limited by the current low level of rates.

In addition to the simulation analysis, an economic value of equity analysis is performed for a longer term view of the interest rate risk position. The economic value of equity analysis begins with an estimate of the economic value of the financial assets, liabilities and off-balance sheet instruments on the Corporation's balance sheet, derived through discounting cash flows based on actual rates at the end of the period. Next, the estimated impact of rate movements is applied to the economic value of assets, liabilities and off-balance sheet instruments. The economic value of equity is then calculated as the difference between the estimated market value of assets and liabilities net of the impact of off-balance sheet instruments. As with net interest income simulation analysis, a variety of alternative scenarios are performed to measure the impact on economic value of equity, including changes in the level, slope and shape of the yield curve.

The table below, as of March 31, 2012 and December 31, 2011, displays the estimated impact on the economic value of equity from a 200 basis point immediate parallel increase or decrease in interest rates. Similar to the simulation analysis above, due to the current low level of interest rates, the economic value of equity analyses below reflect an interest rate scenario of an immediate 25 basis point drop, to zero percent, while the rising interest rate scenario reflects an immediate 200 basis point rise. The change in the sensitivity of the economic value of equity to a 200 basis point parallel increase in rates between December 31, 2011 and March 31, 2012 was primarily driven by changes in market interest rates, increases in noninterest-bearing and lower cost deposits, and forecasted prepayments on the Corporation's mortgage-backed securities portfolio.

Wholesale Funding
The Corporation satisfies liquidity requirements with either liquid assets or various funding sources. Liquid assets, which totaled $11.4 billion at March 31, 2012, compared to $11.2 billion at December 31, 2011, 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, 2012, the Corporation held excess liquidity, represented by $2.9 billion deposited with the FRB, compared to $2.5 billion at December 31, 2011.
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, 2012 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 $414 million at March 31, 2012, compared to $418 million at December 31, 2011.
The Corporation 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. The actual borrowing capacity is contingent on the amount of collateral available to be pledged to the FHLB. As of March 31, 2012, the Corporation had $2.0 billion of outstanding borrowings from the FHLB with remaining maturities ranging from May 2013 to May 2014. Additionally, the Bank had the ability to issue up to $14.8 billion of debt at March 31, 2012 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 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, 2012, 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.

Other Market Risks
Market risk related to the Corporation's trading instruments is not significant, as trading activities are limited. Certain components of the Corporation's noninterest income, primarily fiduciary income, are at risk to fluctuations in the market values of underlying assets, particularly equity and debt securities. Other components of noninterest income, primarily brokerage fees, are at risk to changes in the volume of market activity.
At both March 31, 2012 and December 31, 2011, the Corporation had a $15 million portfolio of investments in indirect private equity and venture capital funds, with commitments of $9 million to fund additional investments in future periods. The value of these investments is at risk to changes in equity markets, general economic conditions and a variety of other factors. The majority of these investments are not readily marketable and are included in “accrued income and other assets” on the consolidated balance sheets. The investments are individually reviewed for impairment on a quarterly basis by comparing the carrying value to the estimated fair value.

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 2011 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, 2011, 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-43 through F-48 in the Corporation’s 2011 Annual Report.
The following is the critical accounting policy for goodwill reflecting the results of the most recent impairment test performed in the first quarter 2012. As of the date of this report, the Corporation does not believe there are any other material changes in the nature or categories of the critical accounting policies or estimates and assumptions from those discussed in the Corporation’s 2011 Annual Report.
Goodwill
Goodwill is the value attributed to unidentifiable intangible elements in acquired businesses. Goodwill is initially recorded at fair value and is subsequently evaluated at least annually for impairment. Goodwill impairment testing is performed at the reporting unit level, equivalent to a business segment or one level below. The Corporation has three reporting units: the Business Bank, the Retail Bank and Wealth Management. At both March 31, 2012 and December 31, 2011, goodwill totaled $635 million, including $380 million allocated to the Business Bank, $194 million allocated to the Retail Bank and $61 million allocated to Wealth Management.
The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and on an interim basis if events or changes in circumstances between annual tests suggest additional testing may be warranted to determine if goodwill might be impaired. The goodwill impairment test is a two-step test. The first step of the goodwill impairment test compares the estimated fair value of identified reporting units with their carrying amount, including goodwill. If the estimated fair value of the reporting unit is less than the carrying value, the second step must be performed to determine the implied fair value of the reporting unit's goodwill and the amount of goodwill impairment, if any.
Estimating the fair value of reporting units is a subjective process involving the use of estimates and judgments related to the selection of inputs such as future cash flows, discount rates, comparable public company multiples, applicable control premiums and economic expectations used in determining the interest rate environment. The estimated fair values of the reporting units are determined using a blend of two commonly used valuation techniques: the market approach and the income approach. For the market approach, valuations of reporting units consider a combination of earnings, equity and other multiples from companies with characteristics similar to the reporting unit. Since the fair values determined under the market approach are representative of noncontrolling interests, the valuations accordingly incorporate a control premium. For the income approach, estimated future cash flows and terminal value are discounted. Estimated future cash flows are derived from internal forecasts and economic expectations for each reporting unit. The applicable discount rate is based on the imputed cost of equity capital appropriate for each reporting unit, which incorporates the risk-free rate of return, the level of non-diversified risk associated with companies with characteristics similar to the reporting unit (beta), an entity-specific risk premium and a market equity risk premium.
In January 2012, the Federal Reserve announced their expectation for the Federal Funds target rate to remain at currently low levels through late 2014. Given the potential for a continued low interest rate environment, the Corporation determined that an interim goodwill impairment test should be performed in the first quarter 2012. As part of the impairment analysis, the Corporation incorporated the Federal Reserve's expectation of the low Federal Fund target rate level through 2014 in its forecasts. In the first quarter 2012, the Corporation engaged an independent valuation specialist to review its valuation models and assumptions. Based on the results of this review and in light of the current rate environment, the Corporation updated its assumptions, discount factors and control premiums. The updated assumptions included maintaining the low Federal funds target rate through the end of 2014. For the years after 2014, the Corporation developed rate assumptions based on the expectation of modest increases in the Federal Funds target rate, eventually reaching a normal interest rate environment. Increases to the fair value of the reporting units were in part a result of the improvement in the stock price of the Corporation as well as the stock prices of the guideline companies used in the market approach. The first step of the interim goodwill impairment test performed in the first quarter 2012 indicated that the estimated fair values of each of the reporting units substantially exceeded their carrying values, including goodwill. The fair value of the Retail Bank exceeded the carrying value by 14 percent. The results of the goodwill impairment test for each reporting unit were subjected to stress testing as appropriate.

63

Table of Contents

Economic conditions impact the assumptions related to interest and growth rates, loss rates and imputed cost of equity capital. The fair value estimates for each reporting unit incorporated current economic and market conditions, including the recent Federal Reserve announcement and the impact of legislative and regulatory changes, to the extent known and as described above. However, further weakening in the economic environment, such as adverse changes in interest rates, a decline in the performance of the reporting units or other factors could cause the fair value of one or more of the reporting units to fall below their carrying value, resulting in a goodwill impairment charge. Additionally, new legislative or regulatory changes not anticipated in management's expectations may cause the fair value of one or more of the reporting units to fall below the carrying value, resulting in a goodwill impairment charge. Any impairment charge would not affect the Corporation's regulatory capital ratios, tangible common equity ratio or liquidity position.

The Tier 1 common capital ratio removes qualifying trust preferred securities from Tier 1 capital as defined by and calculated in conformity with bank regulations. The tangible common equity ratio removes 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.
