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 six months ended June 30, 2011 are not necessarily indicative of the results that may be expected for the year ending December 31, 2011. 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, 2010.

Pending Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income,” (ASU 2011-05). The Corporation will adopt ASU 2011-05, which revises the way in which comprehensive income is presented in the financial statements, in its consolidated financial statements in the first quarter 2012. The provisions of ASU 2011-05 give companies the option to present total comprehensive income, components of net income, and components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. While the provisions of ASU 2011-05 will amend the presentation of comprehensive income, the adoption of ASU 2011-05 will not have any effect on the Corporation’s financial condition and results of operations.

In May 2011, the FASB issued ASU No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” The Corporation will adopt ASU 2011-04, which generally aligns the principles of fair value measurements with International Financial Reporting Standards (IFRSs), in its consolidated financial statements in the first quarter 2012. The provisions of ASU 2011-04 clarify the application of existing fair value measurement requirements, and expand the disclosure requirements for fair value measurements. While the provisions of ASU 2011-04 will increase the Corporation’s fair value disclosures the Corporation does not expect the adoption of ASU 2011-04 to have any effect on the Corporation’s financial condition and results of operations.

In April 2011, the FASB issued ASU No. 2011-02, “Receivables (Topic 310): A Creditor’s Determination of Whether a Restructuring is a Troubled Debt Restructuring,” (ASU 2011-02). The Corporation will adopt ASU 2011-02, which clarifies existing guidance used by creditors to determine when a modification represents a concession, in its consolidated financial statements in the third quarter 2011. While the provisions of ASU 2011-02 may increase the amount of the Corporation’s receivables that are considered troubled debt restructurings and will expand the Corporation’s disclosures on troubled debt restructurings, the Corporation expects minimal impact to the allowance for loan losses and does not expect the adoption of ASU 2011-02 to have a material effect on the Corporation’s financial condition and results of operations.

NOTE 2 –ACQUISITION

On July 28, 2011 (the “acquisition date”), the Corporation acquired all the outstanding common stock of Sterling Bancshares, Inc. (“Sterling”), a bank holding company headquartered in Houston, Texas, in a stock-for-stock transaction. Sterling common shareholders and holders of outstanding Sterling phantom stock units received 0.2365 shares of the Corporation’s common stock in exchange for each share of Sterling common stock or phantom stock unit. As a result, the Corporation issued approximately 24 million common shares, subject to payment of cash in lieu of fractional shares, with an acquisition date fair value of $793 million, based on the Corporation’s closing stock price of $32.67 on July 27, 2011. Based on the merger agreement, outstanding and unexercised options to purchase Sterling common stock were converted into fully vested options to purchase common stock of the Corporation. In addition, outstanding warrants to purchase Sterling common stock were converted into warrants to purchase common stock of the Corporation. The fair value of total consideration paid to acquire Sterling was approximately $803 million. The Corporation incurred $5 million of pre-integration and transaction costs prior to the acquisition closing date that are included in “merger and restructuring charges” in the consolidated statements of income. However, the assets acquired and liabilities assumed from Sterling, the consideration paid to acquire Sterling, and the results of Sterling’s operations are not reflected in consolidated financial statements as of and for the three- and six-month periods ended June 30, 2011. The acquisition of Sterling significantly expands the Corporation’s presence in Texas, particularly in the Houston and San Antonio areas, and gives the Corporation the ability to leverage additional marketing capacity to offer a wide array of products through a larger distribution network, particularly to middle market and small business companies.

NOTE 2 –ACQUISITION (continued)

The assets and liabilities of Sterling were recorded on the consolidated balance sheets at estimated fair value as of the acquisition date. The initial accounting for the acquisition was incomplete at the time these financial statements were issued. The following purchase price allocation is preliminary and may change as additional information becomes available and additional analyses are completed. Preliminary initial goodwill of $469 million was recorded after adjusting for the preliminary fair value of net identifiable assets acquired.

(in millions)	Initial Allocation
Fair value of consideration paid:
Common stock issued (a)	$	793
Warrants issued		7
Stock options issued		3
Cash in lieu of fractional shares (a)
Total consideration paid		803
Fair value of identifiable assets acquired:
Cash and cash equivalents		730
Investment securities available-for-sale		1,527
Total loans		2,109
Premises and equipment		35
Core deposit intangible		41
Accrued income and other assets		288
Total identifiable assets acquired		4,730
Fair value of liabilities assumed:
Deposits		4,076
Short-term borrowings		20
Medium- and long-term debt		262
Accrued expenses and other liabilities		38
Total liabilities assumed		4,396
Fair value of net identifiable assets acquired		334
Goodwill resulting from acquistion	$	469

(a) Due to the limited time since the acquisition date, the number of shares of common stock issued and the amount of cash paid in lieu of fractional shares has yet to be determined. The fair value of common stock issued includes the fair value of any potential fractional shares.

The goodwill resulting from the acquisition represents the inherent long-term value expected from the business opportunities created from combining Sterling with the Corporation. None of the goodwill recognized will be deductible for income tax purposes. Due to the limited time since the acquisition date, the allocation of the preliminary goodwill attributable to the acquisition of Sterling to the Corporation’s business segments was incomplete at the time these financial statements were issued. Additionally, the pro forma revenues and net income of the combined entity are yet to be determined. This information will be included in the Corporation’s Form 10-Q for the period ending September 30, 2011.

The core deposit intangible will be amortized on an accelerated basis over the estimated life, currently expected to be approximately 10 years.

NOTE 2 –ACQUISITION (continued)

In conjunction with the Sterling acquisition, the acquired impaired loan portfolio was accounted for at preliminary fair value as follows.

(In millions)	Impaired Loans
Contractually required principal and interest	$	322
Contractual cash flows not expected to be collected (nonaccretable difference)		165
Expected cash flows		157
Interest component of expected cash flows (accretable yield)		26
Estimated fair value at acquisition	$	131

Information regarding acquired loans not deemed impaired at acquisition was as follows.

(In millions)	Nonimpaired Loans
Contractually required principal and interest	$	2,468
Contractual cash flows not expected to be collected		206
Estimated fair value at acquisition		1,978

Loans acquired in the Sterling acquisition were initially recorded at fair value with no separate allowance for loan losses. The Corporation reviewed the loans at acquisition to determine which loans should be considered purchased impaired loans and aggregated the impaired loans into pools of loans based on common risk characteristics. The Corporation defined impaired loans as those that were either not accruing interest or exhibited credit risk factors consistent with nonperforming loans at the acquisition date.

The Corporation estimated the total cash flows expected to be collected from the pools of loans, which includes undiscounted expected principal and interest. The excess of the total cash flows expected to be collected over the fair value of the related loans represents the accretable yield, which is recognized as interest income on a level-yield basis over the life of the related loans. The difference between the undiscounted contractual principal and interest and the total cash flows expected to be collected is the nonaccretable difference, which reflects the impact of estimated credit losses and other factors. Subsequent decreases in the expected cash flows will require the Corporation to evaluate the need for additions to the allowance for loan losses. Subsequent improvements in expected cash flows will result in the recognition of additional interest income over the then remaining lives of the loan pools.

For acquired loans not deemed impaired at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. Subsequent to the acquisition date, methods utilized to estimate the required allowance for loan losses for these loans is similar to originated loans; however, a provision for loan losses will be recorded only to the extent the required allowance exceeds any remaining credit discounts.

NOTE 3 – 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.

NOTE 3 – FAIR VALUE MEASUREMENTS (continued)

The Corporation categorizes assets and liabilities recorded at fair value 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. These levels are:

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.

Following is a description 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. For financial assets and liabilities recorded at fair value, the description includes 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 securities purchased under agreements to resell, and interest-bearing deposits with banks

Due to the short-term nature, the carrying amount of these instruments approximates the estimated fair value.

Trading securities and associated deferred compensation plan liabilities

Securities held for trading purposes and associated deferred compensation plan liabilities are recorded at fair value 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 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. The fair value of loans held-for-sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Corporation classifies loans held-for-sale subjected to nonrecurring fair value adjustments 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-sponsored enterprises, corporate debt securities and state and municipal 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 are auction-rate securities (ARS), 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 at June 30, 2011, December 31, 2010 and June 30, 2010 was determined using an income approach based on a discounted cash flow model utilizing two significant assumptions: discount rate (including a liquidity risk premium) 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 based on observed industry auction-rate securities valuations by third parties and incorporated the rate at which the various types of similar ARS 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 redemption experience. As of June 30, 2011, approximately 61 percent of the aggregate ARS par value had been redeemed or sold since acquisition at or above carrying value.

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. Impaired loans are reported as nonrecurring fair value measurements when an allowance is established based on the fair value of collateral. When the fair value of the collateral is based on an observable market price or a current appraised value, the Corporation classifies the impaired loan as nonrecurring Level 2. 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 nonrecurring Level 3.

Business loans consist of commercial, real estate construction, commercial mortgage, lease financing and international loans. The estimated fair value for variable rate business loans that reprice frequently is based on carrying values adjusted for estimated credit losses and other adjustments that would be expected to be made by a market participant in an active market. The fair value for other business loans and retail loans are estimated using a discounted cash flow model that employs interest rates currently offered on the loans, adjusted by an amount for estimated credit losses and other adjustments that would be expected to be made by a market participant in an active market. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, when applicable.

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.

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 using internally developed models that use primarily market observable inputs, such as yield curves and option volatilities. Included in the fair value of over-the-counter derivative instruments are credit valuation adjustments reflecting counterparty credit risk and credit risk of the Corporation. 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 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 classified 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 also 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 using a Black-Scholes valuation model with five inputs: risk-free rate, expected life, volatility, exercise price, and the per share market value of the underlying company. The Corporation classifies warrants accounted for as derivatives as recurring Level 3.

NOTE 3 – FAIR VALUE MEASUREMENTS (continued)

The Corporation 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 fair value of the derivative contract was based on unobservable inputs consisting of management’s estimate of the litigation outcome, timing of litigation settlements and payments related to the derivative. The Corporation classifies the derivative liability as recurring Level 3.

Nonmarketable equity securities

The Corporation has a portfolio of indirect 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. For such investments, fair value measurement guidance permits the use of net asset value, provided the net asset value is calculated by the fund in compliance with fair value measurement guidance applicable to investment companies. 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 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 $128 million at June 30, 2011 and December 31, 2010, respectively, and its investment in FRB stock totaled $59 million at both June 30, 2011 and December 31, 2010. The Corporation believes its investments in FHLB and FRB stock are recoverable at par.

The Corporation classifies nonmarketable equity securities subjected to nonrecurring fair value adjustments as Level 3.

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. Foreclosed property carried at fair value based on an observable market price or a current appraised value is classified by the Corporation as nonrecurring Level 2. When management determines that the fair value of the foreclosed property requires additional adjustments, either as a result of a non-current appraisal or when there is no observable market price, the Corporation classifies the foreclosed property as nonrecurring Level 3.

Loan servicing rights

Loan servicing rights, included in “accrued income and other assets” on the consolidated balance sheets, are subject to impairment testing. A valuation model is used for impairment testing, which utilizes a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and a

12

NOTE 3 – FAIR VALUE MEASUREMENTS (continued)

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 subjected to nonrecurring fair value adjustments 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.

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.

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. If quoted market values are not available, the estimated fair value is based on the market values of debt with similar characteristics.

Credit-related financial instruments

The estimated fair value of unused commitments to extend credit and standby and commercial letters of credit is represented by the estimated cost to terminate or otherwise settle the obligations with the counterparties. This amount is approximated by the fees currently charged to enter into similar arrangements, considering the remaining terms of the agreements and any changes in the credit quality of counterparties since the agreements were executed. This estimate of fair value does not take into account the significant value of the customer relationships and the future earnings potential involved in such arrangements as the Corporation does not believe that it would be practicable to estimate a representational fair value for these items.

NOTE 3 – FAIR VALUE MEASUREMENTS (continued)

Estimated Fair Values of Financial Instruments Not Recorded at Fair Value in their Entirety on a Recurring Basis

The Corporation typically holds the majority of its financial instruments until maturity and thus does not expect to realize many of the estimated fair value amounts disclosed. The disclosures also do not include estimated fair value amounts for items that are not defined as financial instruments, but which have significant value. These include such items as core deposit intangibles, the future earnings potential of significant customer relationships and the value of trust operations and other fee generating businesses. The Corporation believes the imprecision of an estimate could be significant.

The carrying amount and estimated fair value of financial instruments not recorded at fair value in their entirety on a recurring basis on the Corporation’s consolidated balance sheets are as follows:

	June 30, 2011						December 31, 2010

(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.

As of June 30, 2011, 94 percent of the Corporation’s auction-rate portfolio was rated Aaa/AAA by the credit rating agencies.

At June 30, 2011, the Corporation had 208 securities in an unrealized loss position with no credit impairment, including 152 auction-rate preferred securities, 30 residential mortgage-backed securities and 26 state and municipal auction-rate securities. 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 June 30, 2011.

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 income, computed based on the adjusted cost of the specific security.

NOTE 4 – INVESTMENT SECURITIES (continued)

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

(in millions)	Amortized		Fair
June 30, 2011	Cost		Value
Contractual maturity
Within one year	$	69	$	69
After one year through five years		466		473
After five years through ten years		55		56
After ten years		6,253		6,397
Subtotal		6,843		6,995
Equity and other nondebt securities:
Auction-rate preferred securities		467		437
Money market and other mutual funds		105		105
Total investment securities available-for-sale	$	7,415	$	7,537

Included in the contractual maturity distribution in the table above were auction-rate securities with a total amortized cost and fair value of $32 million and $26 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 $6,741 million and $6,899 million, 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 June 30, 2011, investment securities with a carrying value of $2.3 billion were pledged where permitted or required by law to secure $1.7 billion of liabilities, primarily public and other deposits of state and local government agencies and derivative instruments.

(a) Includes all loans not included in the categories of special mention, substandard or nonaccrual.

(b) Special mention loans are accruing loans that have potential credit weaknesses that deserve management’s close attention, such as loans to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at some future date. Included in the special mention category were $509 million and $546 million at June 30, 2011 and December 31, 2010, 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. 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, refer to the Nonperforming Assets subheading in Note 1 - Summary of Significant Accounting Policies - on page 76 of the Corporation’s Annual Report for the year ended December 31, 2010. This category is 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.

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. 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 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. For customer-initiated derivatives, the Corporation attempts to minimize credit risk arising from financial instruments by evaluating the creditworthiness of each counterparty, 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 both 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 agencies to collateralize amounts due to either party beyond certain risk limits. At June 30, 2011, counterparties had pledged marketable investment securities to secure approximately 85 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 June 30, 2011 was $114 million, for which the Corporation had pledged collateral of $99 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 June 30, 2011, the Corporation would have been required to assign an additional $15 million of collateral to its counterparties.

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 $4 million and $5 million at June 30, 2011 and December 31, 2010, 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.

NOTE 6 – DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS (continued)

Risk Management

As an end-user, the Corporation employs a variety of financial instruments for risk management purposes, including cash instruments, such as investment securities, as well as derivative instruments. Activity related to these instruments is centered predominantly in the interest rate markets and mainly involves interest rate swaps. Various other types of instruments also may be used to manage exposures to market risks, including interest rate caps and floors, total return swaps, foreign exchange forward contracts and foreign exchange swap agreements.

As part of a fair value hedging strategy, the Corporation entered into interest rate swap agreements for interest rate risk management purposes. These interest rate swap agreements effectively modify the Corporation’s exposure to interest rate risk by converting fixed-rate debt to a floating rate. These agreements involve the receipt of fixed-rate interest amounts in exchange for floating-rate interest payments over the life of the agreement, without an exchange of the underlying principal amount.

Risk management fair value interest rate swaps generated net interest income of $18 million and $36 million for the three- and six-month periods ended June 30, 2011, respectively, compared to net interest income of $20 million and $39 million for the three- and six-month periods ended June 30, 2010, respectively.

The net gains (losses) recognized in other noninterest income (i.e., the ineffective portion) in the consolidated statements of income on risk management derivatives designated as fair value hedges of fixed-rate debt was as follows.

	Three Months Ended June 30,					Six Months Ended June 30,
(in millions)	2011		2010			2011		2010
Interest rate swaps	$	—	$	(1	)	$	1	$	(2	)

As part of a cash flow hedging strategy, the Corporation had entered into interest rate swap agreements that effectively converted a portion of existing and forecasted floating-rate loans to a fixed-rate basis, thus reducing the impact of interest rate changes on future interest income over the life of the agreements. In the first quarter 2011, the remaining $800 million notional amount of interest rate swap agreements outstanding at December 31, 2010 matured. As of June 30, 2011 the Corporation had no interest rate swap agreements designated as cash flow hedges of loans outstanding.

The net gains (losses) recognized in income and OCI on risk management derivatives designated as cash flow hedges of loans for the three- and six-month periods ended June 30, 2011 and 2010 are displayed in the table below.

	Three Months Ended June 30,				Six Months Ended June 30,

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.

NOTE 6 – DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS (continued)

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 income in the three- and six-month periods ended June 30, 2011 and 2010.

The following table summarizes the expected weighted average remaining maturity of the notional amount of risk management interest rate swaps and the weighted average interest rates associated with amounts expected to be received or paid on interest rate swap agreements as of June 30, 2011 and December 31, 2010.

			Weighted Average
(dollar amounts in millions)	Notional Amount		Remaining Maturity (in years)		Receive Rate			Pay Rate (a)
June 30, 2011
Swaps - fair value - receive fixed/pay floating rate
Medium- and long-term debt designation	$	1,450		5.9		5.45	%		0.45	%
Total risk management interest rate swaps	$	1,450
December 31, 2010
Swaps - cash flow - receive fixed/pay floating rate
Variable rate loan designation	$	800		0.1		4.75	%		3.25	%
Swaps - fair value - receive fixed/pay floating rate
Medium- and long-term debt designation		1,600		7.1		5.73			0.85
Total risk management interest rate swaps	$	2,400

(a) Variable rates paid on receive fixed swaps are based on prime and six-month LIBOR rates in effect at June 30, 2011 and December 31, 2010.

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

Fee income is earned from entering into various transactions at the request of customers (customer-initiated contracts), principally foreign exchange contracts, interest rate contracts and energy derivative contracts. For customer-initiated foreign exchange contracts, the Corporation mitigates most of the inherent market risk 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.

For those customer-initiated derivative contracts which were not offset or where the Corporation holds a speculative position within the limits described above, the Corporation recognized an insignificant amount of net gains in “other noninterest income” in the consolidated statements of income in both the three-month periods ended June 30, 2011 and 2010, and an insignificant amount and $1 million of net gains in the six-month periods ended June 30, 2011 and 2010, respectively.

NOTE 6 – DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS (continued)

Fair values of customer-initiated and other derivative instruments represent the net unrealized gains or losses on such contracts and are recorded in the consolidated balance sheets. Changes in fair value are recognized in the consolidated statements of income. The net gains recognized in income on customer-initiated derivative instruments, net of the impact of offsetting positions, were as follows.

		Three Months Ended June 30,				Six Months Ended June 30,
(in millions)	Location of Gain	2011		2010		2011		2010

Additional information regarding the nature, terms and associated risks of derivative instruments can be found in the Corporation’s 2010 Annual Report on page 55 and in Notes 1 and 9 to the consolidated financial statements.

Credit-Related Financial Instruments

The Corporation issues off-balance sheet financial instruments in connection with commercial and consumer lending activities. The Corporation’s credit risk associated with these instruments is represented by the contractual amounts indicated in the following table.

(in millions)	June 30, 2011		December 31, 2010
Unused commitments to extend credit:
Commercial and other	$	23,612	$	23,578
Bankcard, revolving check credit and home equity loan commitments		1,565		1,568
Total unused commitments to extend credit	$	25,177	$	25,146
Standby letters of credit	$	5,282	$	5,453
Commercial letters of credit		132		93
Other credit-related financial instruments		1		1

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 June 30, 2011 and December 31, 2010, the allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, was $30 million and $35 million, respectively.

Unused Commitments to Extend Credit

Commitments to extend credit are legally binding agreements to lend to a customer, provided there is no violation of any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments expire without being drawn upon, the total contractual amount of commitments does not necessarily represent future cash requirements of the Corporation. Commercial and other unused commitments are primarily variable rate commitments. The allowance for credit losses on lending-related commitments included $13 million and $16 million, at June 30, 2011 and December 31, 2010, respectively, for probable credit losses inherent in the Corporation’s unused commitments to extend credit.

At June 30, 2011 and December 31, 2010, commitments to lend additional funds to borrowers whose terms have been modified in troubled debt restructurings totaled $10 million and $7 million, respectively.

NOTE 6 – DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS (continued)

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 2019. 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 $257 million and $298 million of the $5.4 billion and $5.5 billion standby and commercial letters of credit outstanding at June 30, 2011 and December 31, 2010, 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 sheet, totaled $80 million at June 30, 2011, including $63 million of deferred fees and $17 million in the allowance for credit losses on lending-related commitments. At December 31, 2010, the comparable amounts were $83 million, $64 million and $19 million, respectively.

The following table presents a summary of internally classified watch list standby and commercial letters of credit at June 30, 2011 and December 31, 2010. The Corporation’s internal watch list is generally consistent with loans in the Special Mention, Substandard and Doubtful (nonaccrual) 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.

(dollar amounts in millions)	June 30, 2011			December 31, 2010
Total watch list standby and commercial letters of credit	$	233		$	243
As a percentage of total outstanding standby and commercial letters of credit		4.3	%		4.4	%

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 June 30, 2011 and December 31, 2010, the total notional amount of the credit risk participation agreements was approximately $305 million and $316 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 June 30, 2011 and December 31, 2010. In the event of default, the lead bank has the ability to liquidate the assets of the borrower, in which case the lead bank would be required to return a percentage of the recouped assets to the participating banks. As of June 30, 2011, the credit risk participation agreements had a weighted average remaining maturity for outstanding agreements of 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 thousand Visa Class B shares. The fair value of the derivative liability, included in “accrued expenses and other liabilities” on the consolidated balance sheets, was $1 million at both June 30, 2011 and December 31, 2010.

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 require 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 149 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 June 30, 2011 was limited to the book basis of the Corporation’s investment of approximately $337 million, which includes unused 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 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 ($78 million at June 30, 2011).

The Corporation provided no financial or other support that was not contractually required to any of the above VIEs during the six-month periods ended June 30, 2011 and 2010.

The following table summarizes the impact of these VIEs on line items on the Corporation’s consolidated statements of income.

The carrying value of medium- and long-term debt was adjusted to reflect the gain or loss attributable to the risk hedged with interest rate swaps.

All subordinated notes with maturities greater than one year qualify as Tier 2 capital.

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 June 30, 2011.

NOTE 9 – ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

Other comprehensive income (loss) includes the change in net unrealized gains and losses on investment securities available-for-sale, the change in accumulated net gains and losses on cash flow hedges and the change in the accumulated defined benefit and other postretirement plans adjustment. Total comprehensive income was $280 million and $218 million for the six months ended June 30, 2011 and 2010, respectively. The $62 million increase in total comprehensive income for the six months ended June 30, 2011, when compared to the same period in the prior year, resulted primarily from a $77 million increase in net income, partially offset by a $29 million after-tax decrease in net unrealized gains on investment securities available-for-sale. The following table presents reconciliations of the components of accumulated other comprehensive income (loss) for the six months ended June 30, 2011 and 2010.

NOTE 10 – NET INCOME (LOSS) PER COMMON SHARE

Basic and diluted income (loss) from continuing operations per common share and net income (loss) per common share for the three- and six-month periods ended June 30, 2011 and 2010 are presented in the following table.

	Three Months Ended June 30,				Six Months Ended June 30,

The following average shares related to outstanding options to purchase shares of common stock were not included in the computation of diluted net income (loss) per common share because the exercise prices of the options were greater than the average market price of common shares for the period.

	Three Months Ended June  30,				Six Months Ended June  30,

Due to the net loss from continuing operations attributable to common shares for the six months ended June 30, 2010, common stock equivalents for options to purchase 5.1 million shares and warrants to purchase 11.5 million shares, with average exercise prices less than the average market price of common shares for the period, were excluded from the computation of diluted net loss per common share, as their inclusion would have been anti-dilutive.

For further information on the Corporation’s employee benefit plans, refer to Note 18 to the consolidated financial statements in the Corporation’s 2010 Annual Report.

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 interest, state taxes and foreign taxes are then added to the federal tax provision.

Beginning in the first quarter of 2011, the Corporation applied an estimated annual effective tax rate to interim period pre-tax income to calculate the income tax provision for the quarter, in accordance with the principal method prescribed by the accounting guidance established for computing income taxes in interim periods. Prior to 2011, specifically for the interim periods beginning second quarter 2009 through December 31, 2010, the Corporation applied an alternative method permitted under the accounting guidance to calculate interim period income taxes. Under the alternative method, interim period income taxes were based on each discrete quarter’s pre-tax income (loss). The method was used by the Corporation due the volatility and uncertainty in the economy in those periods. Given the diminishing economic volatility and the Corporation’s ability to render more reliable estimates of pre-tax income in 2011, the principal method was applied beginning in the first quarter 2011. The Corporation determined it was impracticable to retroactively apply the principal method to the prior interim periods.

NOTE 12 – INCOME TAXES AND TAX – RELATED ITEMS (continued)

At June 30, 2011, net unrecognized tax benefits were $27 million, compared to net unrecognized tax benefits of $5 million at June 30, 2010. The increase in unrecognized tax benefits of $22 million from June 30, 2010 to June 30, 2011 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 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 $30 million within the next twelve months. Accrued interest payable on tax liabilities was insignificant at June 30, 2011 and $17 million at June 30, 2010. The $17 million decrease in accrued interest from June 30, 2010 to June 30, 2011 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 IRS may question and/or challenge specific interpretative 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 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. 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 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 $3 million and $1 million were included in “litigation and operational losses” on the consolidated statements of income for the six months ended June 30, 2011 and 2010, 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 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 Corporations consolidated financial condition, consolidated results of operations or consolidated cash flows.

NOTE 13 – CONTINGENT LIABILITIES (continued)

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.

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. Information presented is not necessarily comparable with similar information for any other financial institution. 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 June 30, 2011. 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 2010 Annual Report.

NOTE 15 – DISCONTINUED OPERATIONS

In December 2006, the Corporation sold its ownership interest in Munder Capital Management (Munder), an investment advisory subsidiary, to an investor group. The sale agreement included an interest-bearing contingent note.

In the first quarter 2010, the Corporation and the investor group that acquired Munder negotiated a cash settlement of the note receivable for $35 million, which resulted in a $27 million gain ($17 million, after tax), recorded in “income from discontinued operations, net of tax” on the consolidated statements of income. The settlement paid the note in full and concluded the Corporation’s financial arrangements with Munder.

The components of net income from discontinued operations for the six-month period ended June 30, 2010 are shown in the following table. There was no income from discontinued operations for the three-month periods ended June 30, 2011 and 2010 or the six-month period ended June 30, 2011.

Acquisition of Sterling Bancshares, Inc.

On July 28, 2011 (the “acquisition date”), the Corporation acquired all the outstanding common stock of Sterling Bancshares, Inc. (“Sterling”), a bank holding company headquartered in Houston, Texas, in a stock-for-stock transaction. Sterling common shareholders and holders of outstanding Sterling phantom stock units received 0.2365 shares of the Corporation’s common stock in exchange for each share of Sterling common stock or phantom stock unit. As a result, the Corporation issued approximately 24 million common shares, subject to payment of cash in lieu of fractional shares, with an acquisition date fair value of $793 million, based on the Corporation’s closing stock price of $32.67 on July 27, 2011. Based on the merger agreement, outstanding and unexercised options to purchase Sterling common stock were converted into fully vested options to purchase common stock of the Corporation. In addition, outstanding warrants to purchase Sterling common stock were converted into warrants to purchase common stock of the Corporation. The fair value of total consideration paid to acquire Sterling was approximately $803 million. The Corporation incurred $5 million of pre-integration and transaction costs prior to the acquisition closing date that are included in “merger and restructuring charges” in the consolidated statements of income. However, the assets acquired and liabilities assumed from Sterling, the consideration paid to acquire Sterling, and the results of Sterling’s operations are not reflected in consolidated financial statements as of and for the three- and six-month periods ended June 30, 2011. The acquisition of Sterling significantly expands the Corporation’s presence in Texas, particularly in the Houston and San Antonio areas, and gives the Corporation the ability to leverage additional marketing capacity to offer a wide array of products through a larger distribution network, particularly to middle market and small business companies.

Results of Operations

Net income for the three months ended June 30, 2011 was $96 million, an increase of $26 million from $70 million reported for the three months ended June 30, 2010. The increase in net income in the second quarter 2011, compared to the same period in 2010, was primarily due to an $81 million decrease in the provision for credit losses ($79 million decrease in the provision for loan losses and a $2 million decrease in the provision for credit losses on lending-related commitments), partially offset by an increase of $18 million in the provision for income taxes and a $31 million decrease in net interest income. Net income per diluted common share was $0.53 in the second quarter 2011, compared to $0.39 for the same period one year ago.

Net income for the first six months of 2011 was $199 million, an increase of $77 million from $122 million reported for the six months ended June 30, 2010. The increase in net income for the six months ended June 30, 2011 from the comparable 2010 period was primarily due to a $217 million decrease in the provision for credit losses ($205 million decrease in the provision for loan losses and a $12 million decrease in the provision for credit losses on lending-related commitments), partially offset by an increase of $58 million in the provision for income taxes and a decrease of $51 million in net interest income. Net income attributable to common shares was $197 million for the first six months of 2011, compared to a net loss attributable to common shares of $1 million for the same period one year ago. There were no preferred stock dividends included in net income attributable to common shares for the six months ended June 30, 2011, compared to $123 million of preferred stock dividends, including a $94 million one-time redemption charge reflected in the net loss attributable to common shares, for the same period one year ago. The decrease in preferred stock dividends was due to the first quarter 2010 full redemption of $2.25 billion of preferred stock issued to the U.S. Treasury. Diluted net income per common share was $1.10 for the first six months of 2011, compared to a diluted net loss per common share of $0.01 for the comparable 2010 period.

Second-Half 2011 Outlook (Combined Comerica and Sterling Results) Compared to First-Half 2011 (Comerica Only Results)

For the second half of 2011, management expects the following combined results, based on the incorporation of the projected results of Sterling operations from the acquisition closing date of July 28, 2011 through year-end 2011, compared to Comerica-only results for the first half of 2011, assuming a continuation of modest growth in the economy. The estimated purchase accounting impacts incorporated in this outlook are preliminary and may not be indicative of actual amounts that will be recorded as additional information becomes available and as additional analyses are performed.

• A mid-single digit increase in average loans, primarily due to the acquisition of Sterling loans at fair value. The pace of decline of loans in the Commercial Real Estate business line is expected to decrease in the second half of 2011. Average loans in the National Dealer Services business line are expected to be lower in the third quarter and rebound in the fourth quarter of 2011.

• Average earning assets of approximately $52.5 billion, reflecting increases, primarily related to Sterling, in average loans and average investment securities available-for-sale, partially offset by a decrease in excess liquidity.

• An average net interest margin of 3.35 percent to 3.40 percent, reflecting the benefit from the accretion of the purchase discount on the acquired Sterling loan portfolio ($35 million to $45 million; 13 basis points to 17 basis points), a reduction in excess liquidity, no increase in the Federal Funds rate, and LIBOR consistent with second quarter 2011 levels.

• Net credit-related charge-offs between $165 million and $185 million for the second half of 2011. The provision for credit losses is expected to be between $65 million and $85 million for the second half of 2011.

• A mid-single digit decline in noninterest income in the second half of 2011 compared to the first half of 2011, primarily due to the impact of regulatory changes and a reduction of net income from principal investing and warrants, partially offset by the inclusion of Sterling.

• Excluding merger and restructuring charges, a high single-digit increase in noninterest expenses in the second half of 2011 compared to the first half of 2011, primarily due to the addition of Sterling.

• Total merger and restructuring charges of approximately $80 million, after-tax ($125 million pre-tax), with about $25 million, after-tax, recognized in each of the third and fourth quarters of 2011, and the remainder recognized in 2012.

• Total acquisition synergies of approximately 35 percent of Sterling expenses, or about $56 million, with the majority realized in 2012.

• For the second half of 2011, income tax expense to approximate 36 percent of income before income taxes less approximately $33 million in tax benefits.

• Continue share repurchase program that, combined with dividend payments, results in a payout up to 50 percent of full-year earnings.

Net Interest Income

Net interest income was $391 million for the three months ended June 30, 2011, a decrease of $31 million compared to $422 million for the same period in 2010. The decrease in net interest income in the second quarter 2011, compared to the same period in 2010, resulted primarily from a decline in average earning assets, the maturity of interest rate swaps at positive spreads, maturities of higher-yield fixed-rate loans and decreases in LIBOR rates, partially offset by a continued shift in funding sources toward lower-cost funds, along with maturities and redemptions of higher-cost medium- and long-term debt. 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 June 30, 2011, compared to the same period in the prior year. Average earning assets decreased $1.7 billion, or three percent, to $50.1 billion in the second quarter 2011, compared to $51.8 billion in the second quarter 2010, primarily due to a $1.5 billion, or four percent, decrease in average loans, to $39.2 billion. The net interest margin (FTE) for the three months ended June 30, 2011 decreased 14 basis points to 3.14 percent, from 3.28 percent for the comparable period in 2010, primarily due to LIBOR-based loan rates declining faster than deposit rates, a decrease in loan spreads and the maturity of interest rate swaps at positive spreads.

Net interest income was $786 million for the six months ended June 30, 2011, a decrease of $51 million compared to $837 million for the same period in 2010. The decrease in net interest income in the six months ended 2011, compared to the same period in 2010, was primarily due to the same reasons cited in the quarterly discussion above. The “Year-to-date Analysis of Net Interest Income & Rate/Volume – Fully Taxable Equivalent” table provides an analysis of net interest income for the first six months of 2011 on a FTE basis, compared to the same period in the prior year. Average earning assets decreased $2.7 billion, or five percent, to $49.7 billion for the six months ended June 30, 2011, compared to $52.4 billion for the same period in the prior year, primarily due to a $1.6 billion, or four percent, decrease in average loans, to $39.4 billion and a $1.0 billion, or 27 percent, decrease in average interest-bearing deposits with banks. The net interest margin (FTE) for the six months ended June 30, 2011 decreased four basis points to 3.19 percent, from 3.23 percent for the same period in 2010, primarily due to the same reasons cited in the quarterly discussion above, partially offset by a reduction in excess liquidity. The net interest margin was reduced by approximately 18 basis points and 24 basis points in the first six months of 2011 and 2010, respectively, from excess liquidity. Excess liquidity was represented by $2.8 billion and $3.9 billion of average balances deposited with the Federal Reserve Bank (FRB) in the first six months of 2011 and 2010, respectively, included in “interest-bearing deposits with banks” in the consolidated balance sheets. Refer to the “Supplemental Financial Data” section of this financial review for reconcilements of non-GAAP financial measures.

For further discussion of the effects of market rates on net interest income, refer to the “Market Risk” section of this financial review.

For full-year 2011, management expects an average net interest margin of 3.35 percent to 3.40 percent, reflecting the benefit from the accretion of the purchase discount on the acquired Sterling loan portfolio ($35 million to $45 million; 13 basis points to 17 basis points), a reduction in excess liquidity, no increase in the Federal Funds rate, and LIBOR consistent with second quarter 2011 levels.

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 provision for loan losses was $47 million for the second quarter 2011, compared to $126 million for the same period in 2010. The provision for loan losses for the first six months of 2011 was $96 million, compared to $301 million for the same period in 2010. The Corporation establishes this provision to maintain an adequate allowance for loan losses, which is discussed under the “Credit Risk” subheading in the “Risk Management” section of this financial review. The decreases of $79 million and $205 million in the provision for loan losses in the three- and six month periods ended June 30, 2011, respectively, when compared to the same periods in 2010, resulted primarily from improvements in credit quality. Improvements in credit quality included a decline of $715 million, to $4.8 billion, in the Corporation’s watch list loans from December 31, 2010 to June 30, 2011. The Corporation’s internal watch list is generally consistent with loans in the Special Mention, Substandard and Doubtful (nonaccrual) categories defined by regulatory authorities. Additional indicators of improved credit quality included a decrease in the inflow to nonaccrual (based on an analysis of nonaccrual loans with book balances greater than $2 million) of $115 million and a decrease in net credit-related charge-offs of $128 million in the six month period ended June 30, 2011, compared to the same period in the prior year.

Moderate U.S. economic growth through the second half of 2010 gave way to a slow growth “soft patch” in the first half of 2011. Real gross domestic product growth for the first quarter of 2011 registered just 1.9 percent annualized and second quarter growth is expected be about the same. U.S. job growth dwindled in May and June, totaling just 43,000 net new jobs for the two months. Three sets of factors converged to pull the economy into a soft patch. These factors are characterized by their expected duration: transitory, medium term and long term. Transitory factors include bad winter and spring weather, high crude oil and gasoline prices early in the year, and the Japan disaster at the end of March which resulted in supply-chain bottlenecks for U.S. manufacturers. Medium term factors that will weigh on economic growth through the remainder of 2011 include still-weak housing markets, constrained consumer spending, and the state and local government budget crisis. Long term factors dragging on economic growth into 2012 and beyond include a lower rate of population growth, an unwind of various federal government efforts to stimulate the economy, and eventual caps and cuts in federal spending, expected to come as a result of current negotiations on the federal debt ceiling. The Texas economy has maintained some forward momentum through the soft patch, while California and Michigan have experienced mildly deteriorating labor market conditions in the second quarter of 2011. Fortunately, the transitory factors are proving to be transitory. Automobile production is expected to increase through the second half of 2011, stabilizing durable goods manufacturing in the second half of the year. This and other forward-looking indicators point to moderately improving economic conditions in the Corporation’s primary geographic markets in late 2011.

Total net credit-related charge-offs include net charge-offs on both loans and lending-related commitments. Net loan charge-offs for the second quarter 2011 decreased $56 million to $90 million, or 0.92 percent of average total loans, compared to $146 million, or 1.44 percent for the second quarter 2010. The decrease in net loan charge-offs in the second quarter 2011, compared to the second quarter 2010, consisted primarily of decreases in net loan charge-offs in the Middle Market ($34 million) and Commercial Real Estate ($23 million) business lines. By geographic market, net loan charge-offs decreased in all markets, with the exception of Florida, in the second quarter 2011, compared to the same period in 2010, with the largest decreases noted in the Other Markets ($29 million) and Western ($21 million) markets. In the Florida market, net loan charge-offs increased $8 million, primarily due to increases in the Private Banking and Middle Market business lines.

52

Net loan charge-offs for the first six months of 2011 were $191 million, compared to $319 million for the same period in 2010. The $128 million decrease in net loan charge-offs for the first six months of 2011, compared to the same period in 2010, consisted primarily of decreases in net loan charge-offs in the Commercial Real Estate ($98 million), Specialty Businesses ($17 million), and Middle Market ($14 million) business lines, partially offset by an increase in the Global Corporate Banking Business Line ($7 million). By geographic market, net loan charge-offs decreased in all markets, with the exception of Florida, for the six-month period ended June 30, 2011, compared to the same period in 2010, with the largest decreases noted in the Western ($60 million), Other Markets ($33 million) and Texas ($22 million) markets. In the Florida market, net loan charge-offs increased $6 million, primarily due to increases in the Middle Market and Private Banking business lines.

The provision for credit losses on lending-related commitments was a benefit of $2 million and $5 million for the three- and six-month periods ended June 30, 2011, compared to provisions of zero and $7 million for the comparable periods in 2010. The decreases of $2 million and $12 million for the three- and six-month periods ended June 30, 2011, when compared to the same periods in 2010, respectively, resulted primarily from improved credit quality in unfunded commitments in the Midwest, Western and Texas markets. The Corporation establishes this provision to maintain an adequate 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. Lending-related commitment charge-offs were insignificant in both the three- and six-month periods ended June 30, 2011 and 2010.

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

Management expects net credit-related charge-offs between $165 million and $185 million for the second half of 2011. The provision for credit losses is expected to be between $65 million and $85 million for the second half of 2011.

Noninterest Income

Noninterest income was $202 million for the three months ended June 30, 2011, an increase of $8 million, or four percent, compared to $194 million for the same period in 2010, resulting primarily from increases of $5 million in net income from principal investing and warrants and $3 million in net securities gains.

Noninterest income was $409 million for the first six months of 2011, an increase of $21 million, or five percent, compared to the same period in 2010, resulting primarily from increases in net income from principal investing and warrants ($10 million), risk management hedge gains ($7 million), deferred compensation asset returns ($6 million) and net securities gains ($3 million), partially offset by a decrease in service charges on deposit accounts ($5 million).

Management expects a mid-single digit decline in noninterest income for the second half of 2011, compared to the first half of 2011, primarily due to the impact of regulatory changes and a reduction of net income from principal investing and warrants, partially offset by the inclusion of Sterling.

Noninterest Expenses

Noninterest expenses were $409 million for the three months ended June 30, 2011, an increase of $12 million, or three percent, from $397 million for the comparable period in 2010, resulting primarily from increases in salaries expense ($6 million), employee benefits expense ($5 million) and merger and restructuring charges ($5 million), partially offset by a decrease in FDIC insurance expense ($4 million).

Noninterest expenses were $824 million for the first six months of 2011, an increase of $23 million, or three percent, compared to $801 million for the comparable period in 2010. The increase in noninterest expense resulted primarily from increases in salaries expense ($25 million), employee benefits expense ($11 million), merger and restructuring charges ($5 million) and litigation and operational losses ($5 million), partially offset by decreases in the provision for credit losses on lending-related commitments ($12 million) and FDIC insurance expense ($6 million). The increase in salaries expense reflected increases in incentive compensation ($12 million), share-based compensation ($11 million) and deferred compensation asset returns ($6 million) (offset by an increase in deferred compensation asset returns in noninterest income), partially offset by a decrease in regular salaries ($4 million).

53

Excluding merger and restructuring charges related to the acquisition of Sterling, management expects a high single-digit increase in noninterest expenses in the second half of 2011 compared to the first half of 2011, primarily due to the addition of Sterling. Management expects total merger and restructuring charges of approximately $80 million, after-tax ($125 million pre-tax), with about $25 million, after-tax, recognized in each of the third and fourth quarters of 2011, and the remainder recognized in 2012.

Provision for Income Taxes

The provision for income taxes for the second quarter 2011 was $41 million, compared to $23 million for the same period in 2010. The $18 million increase in the provision for income taxes in the three-month period ended June 30, 2011, compared to the same period in 2010, was primarily due to an increase in income before taxes in the second quarter 2011, compared to the same quarter in the prior year, and a $19 million charge related to a final settlement agreement with the Internal Revenue Service involving the repatriation of foreign earnings on a structured investment transaction, partially offset by a release of tax reserves of $9 million due to the Corporation’s planned participation in a recently enacted State of California voluntary compliance initiative. The Corporation has no other investment structures with uncertain tax positions.

For the first six months of 2011, the provision for income taxes was $76 million, an increase of $58 million compared to the same period in 2010. The increase in the provision for income taxes was primarily due to the same reasons cited in the quarterly discussion above.

Net deferred tax assets were $310 million at June 30, 2011, compared to $383 million at December 31, 2010, a decrease of $73 million, resulting primarily from a reduction in deferred tax assets due to decreases in the allowance for loan losses and 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 June 30, 2011 and December 31, 2010. 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. For further information on income taxes, refer to Note 12 to these unaudited consolidated financial statements.

For the second half of 2011, management expects income tax expense to approximate 36 percent of income before income taxes less approximately $33 million in tax benefits.

Income from Discontinued Operations, Net of Tax

In the first six months of 2011, there was no income from discontinued operations, net of tax. Income from discontinued operations, net of tax, for the first six months of 2010 was $17 million, reflecting a first quarter after-tax gain from the cash settlement of a note receivable related to the 2006 sale of an investment advisory subsidiary. For further information on the cash settlement of the note and discontinued operations, refer to Note 15 to these unaudited consolidated financial statements.

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 on 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 discontinued operations and items not directly associated with these business segments or the Finance Division. Note 14 to these unaudited consolidated financial statements presents financial results of these business segments for the six months ended June 30, 2011 and 2010. 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 consolidated financial statements and Note 23 to the consolidated financial statements in the Corporation’s 2010 Annual Report.

(a) Includes discontinued operations and items not directly associated with the three major business segments or the Finance Division.

The Business Bank’s net income of $343 million increased $120 million in the six months ended June 30, 2011, compared to the six months ended June 30, 2010. Net interest income (FTE) of $682 million decreased $10 million in the six months ended June 30, 2011 compared to the same period in the prior year, as the benefit provided by a $1.8 billion increase in average deposits and an increase in loan spreads was offset by a $1.1 billion decrease in average loans. The provision for loan losses of $24 million decreased $195 million from the comparable period in the prior year, primarily reflecting decreases in the Commercial Real Estate (in all markets) and Middle Market (primarily in the Other Markets and Midwest markets) business lines. Net credit-related charge-offs of $126 million decreased $125 million from the comparable period in the prior year, primarily due to a decrease in charge-offs in the Commercial Real Estate business line. Noninterest income of $156 million increased $4 million from the comparable prior year period, primarily due to increases in warrant income ($5 million) and customer derivative income ($3 million), partially offset by a decrease in investment banking fees ($3 million). Noninterest expenses of $316 million decreased $3 million from the same period in the prior year, primarily due to decreases in the provision for credit losses on lending commitments ($12 million), other real estate expense ($3 million) and nominal decreases in other noninterest expense categories, partially offset by increases in allocated corporate overhead expenses ($13 million) and salaries expense ($4 million). The provision for income taxes (FTE) of $155 million for the six month period ended June 30, 2011 increased $72 million, compared to $83 million for the comparable period the prior year, primarily resulting from an increase in income before income taxes.

The net loss for the Retail Bank was $5 million in the six months ended June 30, 2011, compared to a net loss of $10 million in the six months ended June 30, 2010. Net interest income (FTE) of $282 million increased $17 million from the comparable period in the prior year, primarily due to an increase in loan and deposit spreads and the benefit provided by a $724 million increase in average deposits, partially offset by a $469 million decrease in average loans. The provision for loan losses decreased $5 million from the comparable period in the prior year, reflecting a decrease in the Small Business business line (primarily the Midwest market), partially offset by an increase in the Personal Banking business line (primarily the Midwest Market). Net credit-related charge-offs of $46 million decreased $1 million from the comparable period in the prior year. Noninterest income of $87 million increased $1 million from the comparable prior year period, primarily due to nominal increases in other noninterest income categories, partially offset by a $4 million decrease in service charges on deposit accounts. Noninterest expenses of $325 million increased $11 million from the same period in the prior year, primarily due to an increase in allocated corporate overhead expenses ($7 million).

Wealth Management’s net income of $26 million increased $10 million in the six months ended June 30, 2011, compared to the six months ended June 30, 2010. Net interest income (FTE) of $92 million increased $5 million from the comparable period in the prior year, primarily due to increases in loan and deposit spreads. The provision for loan losses decreased $8 million from the comparable period in the prior year, primarily reflecting a decrease in the Midwest market. Net credit-related charge-offs of $19 million decreased $2 million from the comparable period in the prior year, primarily due to a decrease in the Western market, partially offset by an increase in the Florida market. Noninterest income of $128 million increased $6 million from the comparable period in the prior year, primarily due to a $3 million increase in investment banking fees and nominal increases in other noninterest income categories. Noninterest expenses of $155 million increased $2 million, primarily due to an increase in allocated corporate overhead expenses ($4 million).

The net loss for the Finance Division was $164 million in the six months ended June 30, 2011, compared to a net loss of $116 million in the six months ended June 30, 2010. Net interest expense (FTE) increased $74 million in the six months ended June 30, 2011, compared to the same period in the prior year. Net interest expense (FTE) in the Finance Division is primarily impacted by the Corporation’s internal funds transfer methodology. The methodology is designed to centralize interest rate risk in the Finance Division and to measure profitability across all interest rate environments. To that end, the Finance Division pays the three major business segments for the long-

55

term value of deposits based on their assumed lives. The three major business segments pay the Finance Division for funding based on the repricing and term characteristics of their loans. Noninterest income increased $1 million from the comparable period in the prior year, primarily due to a $7 million increase in risk management hedge income, partially offset by a $2 million gain on the repurchase of subordinated debt in the first quarter 2010 and nominal decreases in other noninterest income categories. Noninterest expenses increased $2 million from the same period in the prior year primarily due to a $2 million increase in salaries expense.

The Other category’s net income decreased $10 million to a net loss of $1 million in the six months ended June 30, 2011, compared to the six months ended June 30, 2010. The decrease in net income primarily reflected a $5 million increase in principal investing and warrant income, more than offset by the $17 million after-tax discontinued operations gain recorded in the first quarter 2010.

Market Segments

The Corporation’s management accounting system also produces market segment results for the Corporation’s four primary geographic markets: Midwest, Western, Texas and Florida. In addition to the four primary geographic markets, Other Markets and International are also reported as market segments. Note 14 to these unaudited consolidated financial statements contains a description and presents financial results of these market segments for the six months ended June 30, 2011 and 2010.

Average loans decreased $825 million, or two percent, to $39.2 billion at June 30, 2011, compared to December 31, 2010, reflecting increases in the Global Corporate Banking ($412 million), Middle Market ($254 million) and Energy Lending ($187 million) (included in Specialty Businesses) business lines. These increases were more than offset by decreases in the Commercial Real Estate ($717 million), Mortgage Banker Finance ($487 million) (included in Specialty Businesses), National Dealer Services ($160 million) and Personal Financial Services ($109 million) business lines. Mortgage Banker Finance provides short-term financing to borrowers in the mortgage banking industry who originate and refinance residential mortgage loans which they subsequently sell in the secondary market (mortgage warehousing loans). Average loans in Mortgage Banker Finance, included in “Commercial Loans” on the consolidated balance sheets, declined 44 percent to $614 million at June 30, 2011, compared to $1.1 billion at December 31, 2010, primarily due to a decline in consumer refinance volumes during the three months ended June 30, 2011 compared to the fourth quarter 2010. The decrease in average loans in the National Dealer Services business line primarily reflected the impact of supply-chain disruptions related to the earthquake and tsunami in Japan in March 2011. Average loans in the Commercial Real Estate business line continued to decline, as the Corporation continued to work through the nonperforming portfolio and customers accessed external sources of long-term refinancing. By market, increases in average loans in the Texas ($436 million) and International ($145 million) markets were more than offset by decreases in Other Markets ($828 million), which included Mortgage Banker Finance, Western ($376 million) and Midwest ($168 million) markets.

Management expects average earning assets of approximately $52.5 billion for the second half of 2011, reflecting increases, primarily related to Sterling, in average loans and average investment securities available-for-sale, partially offset by a decrease in excess liquidity. The pace of decline of loans in the Commercial Real Estate business line is expected to decrease in the second half of 2011. Average loans in the National Dealer Services business line are expected to be lower in the third quarter and rebound in the fourth quarter of 2011.

Total liabilities increased $229 million to $48.1 billion at June 30, 2011, compared to December 31, 2010, primarily due to a $1.3 billion increase in total deposits, partially offset by a $932 million decrease in medium- and long-term debt. On an average basis, total liabilities increased $659 million in the second quarter 2011, compared to the fourth quarter 2010. Average core deposits, which exclude other time deposits and foreign office time deposits, were $41.1 billion for the second quarter 2011, compared to $39.9 billion for the fourth quarter 2010, primarily reflecting increases of $905 million in money market and NOW deposits and $179 million in noninterest-bearing deposits. Within average core deposits, increases from the fourth quarter 2010 to the second quarter 2011 were noted in the Global Corporate Banking ($550 million), Specialty Businesses ($550 million), Personal Banking ($420 million, and Private Banking ($248 million) business lines, partially offset by a decrease in the Middle Market business line ($552 million). By geographic market, average core deposits increased in all major markets in the second quarter 2011, compared to the fourth quarter 2010.

These transactions are not considered part of the Corporation’s repurchase program.

(b) The Corporation made no repurchases of warrants under the repurchase program during the six months ended June 30, 2011.

(c) Maximum number of shares and warrants that may yet be purchased under the publicly announced plans or programs.

Management expects to continue the share repurchase program that, combined with dividend payments, results in a payout up to 50 percent of earnings for full-year 2011.

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 leverage ratios increased from December 31, 2010 to June 30, 2011. These increases were primarily due to a decrease in risk-weighted assets resulting from a decrease in loans, partially offset by an increase in interest-bearing deposits with banks, which carry a lower risk weight. The tangible common equity ratio increased 36 basis points primarily due to an increase in tangible common equity, reflecting an increase in retained earnings, partially offset by an increase in tangible assets.

In December 2009, the Basel Committee on Banking Supervision (the Basel Committee) released proposed Basel III guidance on bank capital and liquidity. In September 2010, the Basel Committee proposed higher global minimum capital standards, including a minimum Tier 1 common capital ratio and additional capital and liquidity requirements, with rules 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 certain. The Corporation believes that the expected impacts from changes in the components of capital and the calculation of risk-weighted assets would not be material. A higher degree of uncertainty exists regarding the implementation and interpretation of the liquidity rules. If subject to these rules, the Corporation expects the liquidity requirements to be manageable. 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.

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

	June 30, 2011					December 31, 2010
(dollar amounts in millions)	Capital		Ratio			Capital		Ratio
Tier 1 common (a) (b)	$	6,193		10.53	%	$	6,027		10.13	%

At June 30, 2011, the Corporation and its U.S. banking subsidiaries exceeded the ratios required for an institution to be considered “well capitalized” (Tier 1 risk-based capital, total risk-based capital and leverage ratios greater than six percent, 10 percent and five percent, respectively).

Risk Management

The following updated information should be read in conjunction with the “Risk Management” section on pages 38-60 in the Corporation’s 2010 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 loan losses includes specific allowances, based on individual evaluations of certain loans and loan relationships, and allowances for pools of loans with similar risk characteristics for the remaining business and retail loans. The Corporation defines business loans 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 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 loan losses was $806 million at June 30, 2011, compared to $901 million at December 31, 2010, a decrease of $95 million, or 11 percent. The decrease resulted primarily from improvements in credit quality, including a decline of $715 million in the Corporation’s watch list loans from December 31, 2010 to June 30, 2011, and a $1.0 billion decrease in loan balances from December 31, 2010 to June 30, 2011. The decrease in the allowance for loan losses primarily reflected decreases in the Commercial Real Estate (all markets) and Middle Market (primarily the Midwest and Other markets) business lines, partially offset by an increase in the Middle Market business line in the Western market. The allowance for loan losses as a percentage of total period-end loans was 2.06 percent at June 30, 2011, compared to 2.24 percent at December 31, 2010. Nonperforming loans of $974 million at June 30, 2011 decreased $149 million, compared to December 31, 2010. All large nonperforming loans are individually reviewed each quarter for potential charge-offs and reserves. Charge-offs are taken as amounts are determined to be uncollectible based on a qualitative assessment of the recoverability of the principal amount from collateral and other cash flow sources. A measure of the level of charge-offs already taken on nonperforming loans is the current book balance as a percentage of the contractual amount owed. At June 30, 2011, nonperforming loans were charged-off to 53 percent of the contractual amount, compared to 54 percent at December 31, 2010. This level of write-downs is consistent with losses experienced on loan defaults in the first six months of 2011 and in recent years. The allowance as a percentage of total nonperforming loans, a ratio which results from the actions noted above, was 83 percent at June 30, 2011, compared to 80 percent at December 31, 2010. 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, resulting in a lower nonperforming loan allowance coverage when compared to banking organizations with higher concentrations of consumer loans.

The allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, includes specific allowances, based on individual evaluations of certain letters of credit in a manner consistent with business loans, and allowances based on the pools of the remaining letters of credit and all unused commitments to extend credit within each internal risk rating. A probability of draw estimate is applied to the commitment amount, and the result is multiplied by standard reserve factors consistent with business loans. In general, the probability of draw for letters of credit is considered certain for all letters of credit supporting loans and for letters of credit assigned an internal risk rating generally consistent with regulatory defined substandard or doubtful. Other letters of credit and all unfunded commitments have a lower probability of draw.

61

The allowance for credit losses on lending-related commitments was $30 million at June 30, 2011, a decrease of $5 million from $35 million at December 31, 2010.

Nonperforming assets include loans on nonaccrual status, loans 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 decreased $191 million to $1.0 billion at June 30, 2011, from $1.2 billion at December 31, 2010, and are summarized in the following table.

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, or when the loan is both well secured and in the process of collection. For a further discussion of impaired loans refer to Note 1 to the consolidated financial statements in the Corporation’s 2010 Annual Report.

At June 30, 2011, troubled debt restructurings totaled $212 million, of which $141 million were included in nonperforming loans ($108 million nonaccrual loans and $33 million reduced-rate loans) and $71 million were included in performing loans. Performing restructured loans included $51 million of commercial loans (primarily in the Middle Market and Specialty Businesses business lines) and $20 million of commercial mortgage loans (primarily in the Middle Market business line) at June 30, 2011. At December 31, 2010, troubled debt restructurings totaled $165 million, including $44 million performing restructured loans, $78 million nonaccrual loans and $43 million reduced-rate loans. The $47 million increase in troubled debt restructurings was primarily due to increases in the Specialty Businesses and Middle Market business lines.

Loans past due 90 days or more and still accruing interest generally represent loans that are well collateralized and in a continuing process that is expected to result in repayment or restoration to current status. Loans past due 90 days or more and still accruing increased $2 million, to $64 million at June 30, 2011, compared to $62 million at December 31, 2010 and are summarized in the following table. Loans past due 30-89 days increased $62 million to $343 million at June 30, 2011, compared to $281 million at December 31, 2010.

Commercial and Residential Real Estate Lending

The following table summarizes the Corporation’s commercial real estate loan portfolio by loan category as of June 30, 2011 and December 31, 2010.

(in millions)	June 30, 2011		December 31, 2010
Real estate construction loans:
Commercial Real Estate business line (a)	$	1,343	$	1,826
Other business lines (b)		385		427
Total real estate construction loans	$	1,728	$	2,253
Commercial mortgage loans:

Other business lines (b)		7,649		7,830
Total commercial mortgage loans	$	9,579	$	9,767

(a) Primarily loans to real estate investors and developers.

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

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 $11.3 billion at June 30, 2011, of which $3.3 billion, or 29 percent, were to borrowers in the Commercial Real Estate business line, which includes loans to residential real estate investors and developers. The remaining $8.0 billion, or 71 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 portfolio totaled $1.7 billion at June 30, 2011. The real estate construction loan portfolio primarily contains loans made to long-time customers with satisfactory completion experience. However, the significant and sudden 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 $1.3 billion of real estate construction loans in the Commercial Real Estate business line, $137 million were on nonaccrual status at June 30, 2011, including single family projects totaling $37 million (primarily in the Western and Florida markets), retail projects totaling $35 million (primarily in the Western and Florida markets), residential land development projects totaling $30 million (primarily in the Western market) and multi-use projects totaling $27 million (primarily in the Western market). Real estate construction loan net charge-offs in the Commercial Real Estate business line totaled $14 million for the six months ended June 30, 2011, including $7 million from residential land development projects (primarily in the Western market) and $4 million from multi-use projects (primarily in the Western market).

The commercial mortgage loan portfolio totaled $9.6 billion at June 30, 2011 and included $1.9 billion in the Commercial Real Estate business line and $7.7 billion in other business lines. Of the $1.9 billion of commercial mortgage loans in the Commercial Real Estate business line, $186 million were on nonaccrual status at June 30, 2011, including retail projects totaling $55 million (primarily in the Midwest market), multi-family projects totaling $24 million (primarily in the Florida market), multi-use projects totaling $24 million (primarily in the Other market), single family projects totaling $21 million (primarily in the Other market) and medical office projects totaling $20 million in the Midwest market. Commercial mortgage loan net charge-offs in the Commercial Real Estate business line totaled $9 million for the six months ended June 30, 2011, primarily including net charge-offs of $4 million from multi-family projects (primarily in the Florida market) and $3 million from retail projects in the Midwest market.

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

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, totaled $3.1 billion at June 30, 2011. Residential mortgages totaled $1.5 billion at June 30, 2011, 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, $60 million were on nonaccrual status at June 30, 2011. The home equity portfolio totaled $1.6 billion at June 30, 2011, of which $1.4 billion was outstanding under primarily variable-rate, interest-only home equity lines of credit and $185 million consisted of closed-end home equity loans. Of the $1.6 billion of home equity loans outstanding, $4 million were on nonaccrual status at June 30, 2011. A substantial majority of the home equity portfolio was secured by junior liens.

The Corporation rarely originates residential real estate loans with a loan-to-value ratio 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 any 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 early payment defaults by borrowers or 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 June 30, 2011, the Corporation estimated that, of the $15 million total residential mortgage loans past due 90 days or more and still accruing interest, approximately $2 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 results of the 2011 SNC Exam were reflected in the second quarter 2011 credit metrics. The Corporation generally seeks to obtain ancillary business at the origination of a SNC relationship. Loans classified as SNC loans (approximately 900 borrowers at June 30, 2011) totaled $7.5 billion at June 30, 2011, compared to $7.3 billion at December 31, 2010. SNC net loan charge-offs totaled $13 million and $14 million for the three- and six-month periods ended June 30, 2011, respectively. SNC loans, diversified by both business line and geographic market, comprised approximately 19 percent and 18 percent of total loans at June 30, 2011 and December 31, 2010, respectively. SNC loans are held to the same credit underwriting standards as the remainder of the loan portfolio and face similar credit challenges.

Automotive Lending

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 $1.5 billion at June 30, 2011, a decrease of $539 million compared to $2.0 billion at December 31, 2010, primarily reflecting 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. 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 June 30, 2011 and December 31, 2010. 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 $1.0 billion at June 30, 2011, compared to $831 million at December 31, 2010.

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 June 30, 2011 and December 31, 2010.

(in millions)	June 30, 2011		December 31, 2010
Loans outstanding	$	39	$	27
Lease financing		413		446
Investment securities available-for-sale		26		39
Trading account securities		8		19
Standby letters of credit		78		80
Unused commitments to extend credit		23		12
Total direct exposure to state and local municipalities	$	587	$	623

Indirect exposure comprised $345 million auction-rate preferred securities collateralized by municipal securities at June 30, 2011, compared to $436 million at December 31, 2010. 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 June 30, 2011 and December 31, 2010, 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 June 30, 2011 and December 31, 2010. 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 Portugal, Ireland, Italy, Greece or Spain. 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. Credit limits to banks domiciled in the aforementioned countries totaled less than $15 million at June 30, 2011. In addition, exposure to corporations in the aforementioned European countries was less than $125 million at June 30, 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 June 30, 2011, 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 will 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 both 12 and 24 month time horizons, using simulation modeling analysis as its principal risk management evaluation technique. The results of these analyses provide the information needed to assess the balance sheet structure. Changes in economic activity, whether domestic or international, different from those management included in its simulation analyses 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 twelve 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. 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 these analyses, but no additional hedging is forecasted.

The table below, as of June 30, 2011 and December 31, 2010, 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. These results do not reflect the impact of the acquisition of Sterling. The Corporation expects the sensitivity of net interest income to changes in interest rates will not be materially different with the addition of Sterling.

	June 30, 2011						December 31, 2010
(dollar amounts in millions)	Amount			%			Amount			%
Sensitivity of net interest income to changes in interest rates:
+200 basis points	$	118			8	%	$	104			7	%
- 25 basis points (to zero percent)		(17	)		(1	)		(15	)		(1	)

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 and liabilities on the Corporation’s balance sheet, derived through discounting cash flows based on actual rates at the end of the period, and then applies the estimated impact of rate movements 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 shocks, 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.

70

The table below, as of June 30, 2011 and December 31, 2010, 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, 2010 and June 30, 2011 was primarily driven by changes in market interest rates, deposit mix, and the Corporation’s mortgage-backed securities portfolio’s forecasted prepayments.

	June 30, 2011						December 31, 2010
(dollar amounts in millions)	Amount			%			Amount			%
Sensitivity of economic value of equity to changes in interest rates:
+200 basis points	$	365			4	%	$	435			5	%
- 25 basis points (to zero percent)		(96	)		(1	)		(100	)		(1	)

Wholesale Funding

The Corporation satisfies liquidity requirements with either liquid assets or various funding sources. Liquid assets, which totaled $8.8 billion at June 30, 2011, compared to $7.8 billion at December 31, 2010, provide a reservoir of liquidity. Liquid assets include cash and due from bank, federal funds sold and securities purchased under agreements to resell, interest-bearing deposits with banks, other short-term investments and unencumbered investment securities available-for-sale. At June 30, 2011, the Corporation held excess liquidity, represented by $2.4 billion deposited with the FRB, compared to $1.3 billion at December 31, 2010.

The Corporation may access the purchased funds market when necessary, which includes certificates of deposit issued to institutional investors in denominations in excess of $100,000 and to retail customers in denominations of less than $100,000 through brokers (“other time deposits” on the consolidated balance sheets), foreign office time deposits and short-term borrowings. Purchased funds totaled $435 million at June 30, 2011, compared to $562 million at December 31, 2010. Capacity for incremental purchased funds at June 30, 2011, consisted largely of federal funds purchased, brokered certificates of deposits and securities sold under agreements to repurchase. In addition, 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 June 30, 2011, the Corporation had $2.0 billion of outstanding borrowings from the FHLB with remaining maturities ranging from May 2013 to May 2014. The Corporation also maintains a shelf registration statement with the Securities and Exchange Commission from which it may issue debt and/or equity securities. Additionally, the Bank had the ability to issue up to $14 billion of debt at June 30, 2011 under an existing $15 billion medium-term senior note program which allows the issuance of debt with maturities between three months and 30 years.

Other Market Risks

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 June 30, 2011, the Corporation had a $16 million portfolio of investments in indirect private equity and venture capital funds, with commitments of $6 million to fund additional investments in future periods, compared to a portfolio of $47 million at December 31, 2010. During the six months ended June 30, 2011, the Corporation sold 49 funds for a total of $33 million and recognized a net gain of $2 million. 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.

For further discussion of market risk, see Note 6 to these unaudited consolidated financial statements and pages 52-59 in the Corporation’s 2010 Annual Report.

The Dodd-Frank Wall Street Reform and Consumer Protection Act

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Financial Reform Act”) was signed into law. The Financial Reform Act provides for, among other matters, increased regulatory supervision and examination of financial institutions, the imposition of more stringent capital requirements on financial institutions and increased regulation of derivatives and hedging transactions. Provided below is an overview of key elements of the Financial Reform Act relevant to the Corporation. Most of the provisions contained in the Financial Reform Act will be effective immediately upon enactment; however, many have delayed effective dates. Implementation of the Financial Reform Act will require many new mandatory and discretionary rules to be made by federal regulatory agencies over the next several years. The estimates of the impact on the Corporation discussed below are based on the limited information currently available and, given the uncertainty of the timing and scope of the impact, are subject to change until final rulemaking is complete.

• Interest on Demand Deposits: Allows interest on commercial demand deposits, which could lead to increased cost of commercial demand deposits, depending on the interplay of interest, deposit credits and service charges.

• Unlimited Deposit Insurance Extension: Provides unlimited deposit insurance on noninterest-bearing accounts from December 31, 2010 to December 31, 2012. There will not be a separate assessment for unlimited deposit insurance coverage for this period.

• Deposit Insurance: Changes the definition of assessment base from domestic deposits to net assets (average consolidated total assets less average tangible equity), increases the deposit insurance fund’s minimum reserve ratio and permanently increases general deposit insurance coverage from $100,000 to $250,000. The Corporation expects 2011 FDIC insurance expense to be lower than the 2010 expense.

• Derivatives: Allows continued trading of foreign exchange and interest rate derivatives. Requires banks to shift energy, uncleared commodities and agriculture derivatives to a separately capitalized subsidiary within their holding company. Directly impacts client-driven energy derivatives business (approximately $1 million in annual revenue, based on full-year 2010).

• Interchange Fee: Limits debit card transaction processing fees that card issuers can charge to merchants. Based on the final Federal Reserve Board rules, estimated annual revenue from debit card PIN and signature-based interchange fees in 2011 is expected to decrease by approximately $4 million, compared to full-year 2010.

• Trust Preferred Securities: Prohibits holding companies with more than $15 billion in assets from including trust preferred securities as Tier 1 capital, and allows for a phase-in period of three years, beginning January 1, 2013. As of June 30, 2011, the Corporation had no outstanding trust preferred securities.

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 2010 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, 2010, the most critical of these significant accounting policies were the policies related to 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 60-68 in the Corporation’s 2010 Annual Report. As of the date of this report, the Corporation does not believe that there has been a material change in the nature or categories of the critical accounting policies or estimates and assumptions from those discussed in the Corporation’s 2010 Annual Report.

(a) Excess liquidity represented by interest earned on and average balances deposited with the FRB.

(b) Tier 1 capital and risk-weighted assets as defined by regulation.

(c) June 30, 2011 Tier 1 capital and risk-weighted assets are estimated.

The net interest margin (FTE), excluding excess liquidity, removes interest earned on balances deposited with the FRB from net interest income (FTE) and average balances deposited with the FRB from average earning assets from the numerator and denominator of the net interest margin (FTE) ratio, respectively. The Corporation believes this measurement provides meaningful information to investors, regulators, management and others of the impact on net interest income and net interest margin resulting from the Corporation’s short-term investment in low yielding instruments.

The Tier 1 common capital ratio removes preferred stock and qualifying trust preferred securities from Tier 1 capital as defined by and calculated in conformity with bank regulations. The tangible common equity ratio removes preferred stock and the effect of intangible assets from capital and the effect of intangible assets from total assets. 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.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

For information regarding the Corporation’s legal proceedings, see “Part I. Item 1. Note 13 – Contingent Liabilities,” which is incorporated herein by reference.

ITEM 1A. Risk Factors

Other than as set forth below, there has been no material change in the Corporation’s risk factors as previously disclosed in our Form 10-K for the fiscal year ended December 31, 2010 in response to Part I, Item 1A. of such Form 10-K. Such risk factors are incorporated herein by reference.

Below we amend the following risk factor discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2010:

General political, economic or industry conditions, either domestically or internationally, may be less favorable than expected.

Local, domestic, and international economic, political and industry specific conditions affect the financial services industry, directly and indirectly. Conditions such as or related to inflation, recession, unemployment, volatile interest rates, international conflicts and other factors, such as real estate values, energy costs, fuel prices, state and local municipal budget deficits and government spending and the U.S. national debt, outside of our control may, directly and indirectly, adversely affect Comerica. As has been the case with the impact of recent economic conditions, economic downturns could result in the delinquency of outstanding loans, which could have a material adverse impact on Comerica’s earnings.
