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, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010. 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, 2009.

Recently Adopted Accounting Changes

Consolidation

On January 1, 2010, the Corporation adopted Accounting Standards Update (ASU) No. 2009-17, “Improvements in Financial Reporting by Enterprises Involved with Variable Interest Entities,” (ASU 2009-17). ASU 2009-17 amends consolidation guidance related to variable interest entities (VIEs) by replacing a quantitative approach for determining which enterprise, if any, is the primary beneficiary and required to consolidate a VIE with a qualitative approach. The qualitative approach is focused on identifying which enterprise has both the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits that could be significant to the VIE. ASU 2009-17 requires reconsideration of the primary beneficiary whenever circumstances change and eliminates the exception for qualifying special-purpose entities from consolidation guidance.

In February 2010, the Financial Accounting Standards Board (FASB) issued ASU No. 2010-10, “Amendments for Certain Investment Funds,” (ASU 2010-10). ASU 2010-10 indefinitely defers the requirements of ASU 2009-17 for certain investment funds with attributes of an investment company specified in the accounting guidance, including, but not limited to, venture capital funds, private equity funds and mutual funds. The deferral is also applicable to a reporting enterprise’s interest in an entity that is required to comply with or operates in accordance with requirements similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. For funds that qualify for the deferral, the Corporation will continue to analyze whether such funds should be consolidated under authoritative guidance that existed prior to the issuance of ASU 2009-17.

The Corporation was not required to consolidate any additional VIEs with which the Corporation is involved as a result of implementing the guidance in ASU 2009-17, as amended by ASU 2010-10. See Note 6 for additional information about the Corporation’s involvement with VIEs.

Transfers of Financial Assets

On January 1, 2010, the Corporation adopted ASU No. 2009-16, “Transfers and Servicing (Topic 860): Accounting for Transfers of Financial Assets,” (ASU 2009-16). ASU 2009-16 eliminates the concept of qualifying special-purpose entities and establishes conditions for reporting the transfer of a portion of a financial asset as a sale. If the transfer does not meet these established conditions, the transferor and transferee must account for the transfer as a secured borrowing. An enterprise that continues to transfer portions of a financial asset that do not meet these established conditions is eligible to record a sale only after it has transferred all of its interest in that asset. The adoption of ASU 2009-16 was not material to the Corporation’s financial condition and results of operations.

Fair Value Measurements

In the first quarter 2010, the Corporation fully adopted ASU No. 2010-06, “Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements,” (ASU 2010-06). ASU 2010-06 requires separate disclosures of significant transfers in and out of Level 1 and Level 2 fair value measurements and the reasons for the transfers and requires disclosure of purchases, sales, issuances and settlements activity on a gross (rather than net) basis in the Level 3 reconciliation of fair value measurements for assets and liabilities measured at fair value on a recurring basis. In addition, ASU 2010-6 clarifies that fair value measurement disclosures should be provided for each class of assets and liabilities and that disclosures of inputs and valuation techniques should be provided for both recurring and nonrecurring Level 2 and Level 3 fair value measurements. For further information concerning fair value measurements, refer to Note 2.

Note 1 - Basis of Presentation and Accounting Policies (continued)

Pending Accounting Pronouncements

In July 2010, the FASB issued ASU No. 2010-20, “Receivables (Topic 310): Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses,” (ASU 2010-20). ASU 2010-20 requires enhanced disclosures about an entity’s credit quality of financing receivables and the related allowance for credit losses. The Corporation will adopt the period-end provisions of ASU 2010-20 in its consolidated financial statements for the year ended December 31, 2010 and the activity-related provisions of ASU 2010-20 in the first quarter 2011. While the provisions of ASU 2010-20 will require significant expansion of the Corporation’s disclosures on the credit quality of financing receivables and the allowance for credit losses, the Corporation does not expect the adoption of ASU 2010-20 to have a material effect on the Corporation’s financial condition and results of operations.

Note 2 — Fair Value Measurements

The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Trading securities, investment securities available-for-sale, derivatives and deferred compensation plan liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, the Corporation may be required to record other assets and liabilities at fair value on a nonrecurring basis, such as impaired loans, other real estate (primarily foreclosed property), nonmarketable equity securities and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve write-downs of individual assets or application of lower of cost or fair value accounting.

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

Cash and due from banks, federal funds sold and 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.

Note 2 — Fair Value Measurements (continued)

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, 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, 2010, December 31, 2009 and June 30, 2009 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 ARS had been redeemed or sold since acquisition in 2008. As of June 30, 2010, approximately 34% of the aggregate ARS portfolio had been redeemed or sold at par since acquisition. 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.

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.

Note 2 — Fair Value Measurements (continued)

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, consumer loans and residential mortgage 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 assets and derivative liabilities are included in “accrued income and other assets” and “accrued expenses and other liabilities,” respectively, on the consolidated balance sheets. 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.

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.

Note 2 — Fair Value Measurements (continued)

Nonmarketable equity securities

The Corporation has a portfolio of indirect (through funds) private equity and venture capital investments. These funds generally cannot be redeemed and the majority are not readily marketable. Distributions from these funds are received by the Corporation as a result of the liquidation of underlying investments of the funds and/or as income distributions. It is estimated that the underlying assets of the funds will be liquidated over a period of up to 15 years. The value of these investments is at risk to changes in equity markets, general economic conditions and a variety of other factors. The investments are accounted for on the cost or equity method and are individually reviewed for impairment on a quarterly basis by comparing the carrying value to the estimated fair value. Fair value measurement guidance permits the measurement of investments of this type on the basis 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 $230 million and $271 million at June 30, 2010 and December 31, 2009, respectively, and its investment in FRB stock totaled $60 million and $59 million at June 30, 2010 and December 31, 2009, respectively. The Corporation believes its investments in FHLB and FRB stock are ultimately 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. Upon transfer from the loan portfolio, foreclosed property is adjusted to and subsequently carried at the lower of carrying value or fair value, less estimated costs to sell. Fair value is based upon independent market prices, appraised value or management’s estimation of the value. When the fair value of the property is based on an observable market price or a current appraised value, the Corporation classifies the foreclosed property as nonrecurring Level 2. When management determines that the fair value of the foreclosed property requires additional adjustments, either as a result of non-current appraisal value 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 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.

Goodwill

Goodwill, included in “accrued income and other assets” on the consolidated balance sheets, is subject to impairment testing that requires an estimate of the fair value of the Corporation’s reporting units. Estimating the fair value of reporting units is a subjective process involving the use of estimates and judgments, particularly related to future cash flows, discount rates (including market risk premiums) and market multiples. The fair values of the reporting units are determined using a blend of two commonly used valuation techniques: the market approach and the income approach. The Corporation gives consideration to two valuation techniques, as either technique can be an indicator of value. For the market approach, valuations of reporting units are based on an analysis of relevant price multiples in market trades in industries similar to the reporting unit. Market trades do not consider a control premium associated with an acquisition or a sale transaction. For the income approach, estimated future cash flows and terminal value (value at the end of the cash flow period, based on price multiples) were discounted. The discount rate was based on the imputed cost of equity capital appropriate for each reporting unit. Material assumptions used in the valuation models include the comparable public company price multiples used in the terminal value, future cash flows and the market risk premium component of the discount rate. Due to the general uncertainty and depressed earning capacity in the financial services industry as of the measurement date, the Corporation concluded that the valuation under the income approach more clearly reflected the long-term future earning capacity of the reporting units, rather than the valuation under the market approach, and thus gave greater weight to the income approach.

If goodwill impairment testing resulted in impairment, the Corporation would classify goodwill 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.

(a) The Corporation recorded $315 million and $439 million in fair value losses on impaired loans (included in “provision for loan losses” on the consolidated statements of income) during the six months ended June 30, 2010 and 2009, respectively, based on the estimated fair value of the underlying collateral.

(b) The Corporation recorded $3 million and $4 million in fair value losses related to write-downs on nonmarketable equity securities (included in “other noninterest income” on the consolidated statements of income) during the six months ended June 30, 2010 and 2009, respectively, based on the estimated fair value of the funds. At June 30, 2010 and December 31, 2009, commitments to fund additional investments in nonmarketable equity securities recorded at fair value on a nonrecurring basis totaled approximately $5 million and $3 million, respectively.

(c) The Corporation recorded $13 million and $10 million in fair value losses related to write-downs of other real estate, based on the estimated fair value of the property, and recognized net gains of $2 million and and net losses of $1 million on sales of other real estate during the six months ended June 30, 2010 and 2009, respectively, (included in “other real estate expense” on the consolidated statements of income).

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

Disclosure of the estimated fair values of financial instruments, which differ from carrying values, 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.

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

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

(a) Primarily auction-rate securities.

Investment securities in an unrealized loss position are reviewed quarterly for possible other-than-temporary impairment (OTTI). If the Corporation intends to sell securities in an unrealized loss position or it is more likely than not that the Corporation will be required to sell the securities prior to recovery of the amortized cost basis, the Corporation would recognize an OTTI impairment loss in “net securities gains” on the consolidated statements of income for the full difference between the amortized cost and the fair value of those securities. If the Corporation does not intend to sell the securities and it is not more likely than not that it will be required to sell the securities prior to recovery of the amortized cost basis, the Corporation would recognize an OTTI loss consisting of the credit loss on the securities only if full collection of the carrying amount of the securities is not expected. Such OTTI loss would be recognized as “net securities gains” in the consolidated statements of income. Amounts relating to factors other than credit are recorded in other comprehensive income (loss) (OCI). The Corporation 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.

Note 3 - Investment Securities (continued)

At June 30, 2010, the Corporation had 302 securities in an unrealized loss position which had no credit impairment, including 229 auction-rate preferred securities, 40 auction-rate debt securities and 29 state and municipal auction-rate securities. The unrealized losses for these securities resulted from changes in market interest rates and liquidity, not from changes in the probability of collecting the full carrying amount of the securities. The Corporation does not consider these securities to be other-than-temporarily impaired at June 30, 2010.

The Corporation does not expect to collect the full carrying amount of seven state and municipal auction-rate securities (a single issuer) and recognized less than $1 million of credit-related OTTI impairment loss in “net securities gains” in the consolidated statements of income and less than $0.5 million of OTTI impairment relating to all other factors in OCI in the six months ended June 30, 2010 for these securities.

Sales, calls and write-downs of investment securities available-for-sale resulted in the following realized gains and losses, computed based on the adjusted cost of the specific security.

	Six Months Ended June 30,
(in millions)	2010			2009

Securities gains	$	9		$	128
Securities losses	(6		)	(2		)
Total net securities gains	$	3		$	126

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, 2010	Cost		Value

Contractual maturity
Within one year	$	121	$	121

Auction-rate preferred securities	622		609
Money market and other mutual funds	98		98
Total investment securities available-for-sale	$	7,024	$	7,188

Included in the contractual maturity distribution in the table above were auction-rate securities with a total amortized cost and fair value of $103 million and $93 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 $6,078 million and $6,265 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, 2010, investment securities having a carrying value of $4.0 billion were pledged where permitted or required by law to secure $3.7 billion of liabilities, including public and other deposits, FHLB advances and derivative instruments. This included residential mortgage-backed securities of $2.1 billion pledged with the FHLB to secure advances of $2.1 billion at June 30, 2010. The remaining pledged securities of $1.9 billion were primarily with state and local government agencies to secure $1.6 billion of deposits and other liabilities.

Note 5 - Derivative and Credit-Related Financial Instruments

In the normal course of business, the Corporation enters into various transactions involving derivative and credit-related financial instruments to manage exposure to fluctuations in interest rate, foreign currency and other market risks and to meet the financing needs of customers. 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.

Note 5 - Derivative and Credit-Related Financial Instruments (continued)

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, 2010, counterparties had pledged marketable investment securities to secure approximately 80 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, 2010 was $148 million, for which the Corporation had pledged collateral of $139 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, 2010, the Corporation would have been required to assign an additional $17 million of collateral to its counterparties.

The Corporation had commitments to purchase $14 million of when-issued investment securities for its trading securities portfolio at June 30, 2010. Outstanding commitments expose the Corporation to both credit and market risk.

Derivative Instruments

The following table presents the composition of the Corporation’s derivative instruments held or issued for risk management purposes or in connection with customer-initiated and other activities at June 30, 2010 and December 31, 2009. The table excludes commitments, warrants accounted for as derivatives and a derivative related to the Corporation’s 2008 sale of its remaining ownership of Visa shares.

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 $2 million and $4 million at June 30, 2010 and December 31, 2009, 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 5 - 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 $20 million and $39 million for the three- and six-month periods ended June 30, 2010, respectively, compared to net interest income of $14 million and $26 million for the three- and six-month periods ended June 30, 2009, 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)	2010			2009			2010			2009

Interest rate swaps	$	(1	)	$	(1	)	$	(2	)	$	(2	)

As part of a cash flow hedging strategy, the Corporation entered into predominantly two-year interest rate swap agreements (weighted-average original maturity of 2.2 years) that effectively convert 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 (currently over the next 9 months). Approximately four percent ($1.7 billion) of the Corporation’s outstanding loans were designated as hedged items to interest rate swap agreements at June 30, 2010. If interest rates, interest yield curves and notional amounts remain at current levels, the Corporation expects to reclassify $8 million of net gains, net of tax, on derivative instruments designated as cash flow hedges from accumulated other comprehensive income (loss) to earnings during the next twelve months due to receipt of variable interest associated with existing and forecasted floating-rate loans.

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, 2010 and 2009 are displayed in the table below.

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

Gain reclassified from accumulated OCI into interest and fees on loans (effective portion)	9		9			17			17

Foreign exchange rate risk arises from changes in the value of certain assets and liabilities denominated in foreign currencies. The Corporation employs spot and forward contracts in addition to swap contracts to manage exposure to these and other risks.

The 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, 2010 and December 31, 2009.

Swaps - fair value - receive fixed/pay floating rate
Medium- and long-term debt designation	1,600		8.1	5.73		1.01
Total risk management interest rate swaps	$	3,300

(a) Variable rates paid on receive fixed swaps are based on prime and LIBOR (with various maturities) rates in effect at June 30, 2010 and December 31, 2009.

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 in “other noninterest income” in the consolidated statements of income net gains of less than $0.5 million in both the three-month periods ended June 30, 2010 and 2009, and $1 million of net gains in both the six-month periods ended June 30, 2010 and 2009, respectively.

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.

	June 30,		December 31,
(in millions)	2010		2009

Unused commitments to extend credit:
Commercial and other	$	22,795	$	22,451

Total unused commitments to extend credit	$	24,656	$	24,368

Standby letters of credit	$	5,554	$	5,652
Commercial letters of credit	102		104
Other credit-related financial instruments	2		—

The Corporation maintains an allowance to cover probable credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. At June 30, 2010 and December 31, 2009, the allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, was $44 million and $37 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 carrying value of the Corporation’s unused commitments to extend credit totaled $19 million and $20 million, at June 30, 2010 and December 31, 2009, respectively, which was included in the allowance for credit losses on lending-related commitments.

At June 30, 2010 and December 31, 2009, commitments to lend additional funds to borrowers whose terms have been modified in troubled debt restructurings totaled $2 million and $5 million, respectively.

Standby and Commercial Letters of Credit

Standby and commercial 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 and are short-term in nature. 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 $341 million and $404 million of the $5.7 billion and $5.8 billion standby and commercial letters of credit outstanding at June 30, 2010 and December 31, 2009, 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 $75 million at June 30, 2010, including $50 million of deferred fees and $25 million in the allowance for credit losses on lending-related commitments. At December 31, 2009, the comparable amounts were $70 million, $53 million and $17 million, respectively.

The following table presents a summary of total internally classified watch list standby and commercial letters of credit (generally consistent with regulatory defined special mention, substandard and doubtful) at June 30, 2010 and December 31, 2009. 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, 2010			December 31, 2009
Total watch list standby and commercial letters of credit	$	327		$	432

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, 2010 and December 31, 2009, the total notional amount of the credit risk participation agreements was approximately $374 million and $523 million, respectively, and the fair value for each period was a liability of less than $0.5 million, which is included in customer-initiated interest rate contracts recorded in “accrued expenses and other liabilities” on the consolidated balance sheets. The maximum estimated exposure to these agreements, as measured by projecting a maximum value of the guaranteed derivative instruments, assuming 100% default by all obligors on the maximum values, was approximately $15 million and $18 million at June 30, 2010 and December 31, 2009, respectively. As of June 30, 2010, the credit risk participation agreements had a weighted average remaining maturity for outstanding agreements of 1.9 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 was $2 million and less than $0.5 million at June 30, 2010 and December 31, 2009, respectively, included in “accrued expenses and other liabilities” on the consolidated balance sheets.

Note 6 — Variable Interest Entities (VIEs)

The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE and whether the Corporation is the primary beneficiary and should consolidate the entity based on the variable interests it held both at inception and when there is a change in circumstances that 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 140 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, 2010 was limited to the book basis of the Corporation’s investment of approximately $324 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 ($52 million at June 30, 2010).

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, 2010 and 2009.

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.

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 $17 billion of real estate-related loans and $2 billion of mortgage-backed investment securities at June 30, 2010.

In the first quarter 2010, the Bank exercised its option to redeem, at par, a $150 million, 7.125% subordinated note, which had an original maturity date of 2013, and recognized a pre-tax gain of $2 million resulting from the previous termination of a related interest rate swap. In addition, the Bank repurchased, at a discount, $15 million of floating rate medium-term notes maturing in 2011 in the first quarter 2010.

Note 8 - 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 (loss) was $218 million and $(6) million for the six months ended June 30, 2010 and 2009, respectively. The $224 million increase in total comprehensive income for the six months ended June 30, 2010, when compared to the same period in the prior year, resulted primarily from a $135 million after-tax increase in net unrealized gains on investment securities available-for-sale and a $95 million increase in net income. The following table presents reconciliations of the components of accumulated other comprehensive income (loss) for the six months ended June 30, 2010 and 2009.

In 2008, the Corporation issued warrants to the U.S. Department of Treasury (the U.S. Treasury) to purchase 11.5 million shares of common stock at $29.40 per share in connection with the Capital Purchase Program. In the second quarter 2010, the Corporation registered the warrants with the Securities and Exchange Commission and the U.S. Treasury auctioned the warrants to the public. The warrants are listed and traded on the New York Stock Exchange.

Basic income (loss) from continuing operations per common share and net income (loss) per common share are calculated using the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each share of common stock and participating securities according to dividends declared (distributed earnings) and participation rights in undistributed earnings. Distributed and undistributed earnings are allocated between common and participating security shareholders based on their respective rights to receive dividends. Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are considered participating securities (i.e., nonvested restricted stock). Undistributed net losses are not allocated to nonvested restricted shareholders, as these shareholders do not have a contractual obligation to fund the losses incurred by the Corporation. Income (loss) from continuing operations attributable to common shares and net income (loss) attributable to common shares are then divided by the weighted-average number of common shares outstanding during the period, net of nonvested restricted shares.

Note 9 — Net Income (Loss) per Common Share (continued)

Diluted income (loss) from continuing operations per common share and net income (loss) per common share consider common stock issuable under the assumed exercise of stock options granted under the Corporation’s stock plans and warrants. Diluted income (loss) from continuing operations attributable to common shares and net income (loss) attributable to common shares are then divided by the total of weighted-average number of common shares and common stock equivalents outstanding during the period, net of nonvested restricted shares.

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 for these options and warrants were greater than the average market price of common shares for the period.

	Three Months Ended		Six Months Ended
	June 30,		June 30,
(shares in millions)	2010	2009	2010	2009

Average shares related to outstanding options and warrants	13.9	28.9	14.4	29.6
Range of exercise prices	$40.32 - $64.50	$21.06 - $64.50	$39.19 - $64.50	$19.00 - $66.81

Due to the net loss from continuing operations attributable to common shares reported for the six months ended June 30, 2010, less than 0.5 million common stock equivalents for options to purchase 5.1 million shares and 2 million of common stock equivalents for warrants to purchase 11.5 million shares were excluded from the computation of diluted net loss from continuing operations per share and diluted net loss per share, as their inclusion would have been anti-dilutive.

Note 10 — Employee Benefit Plans

Net periodic benefit costs are charged to “employee benefits expense” on the consolidated statements of income. The components of net periodic benefit cost for the Corporation’s qualified pension plan, non-qualified pension plan and postretirement benefit plan are as follows:

Note 11 - Income Taxes and Tax-Related Items

The provision (benefit) for federal income taxes is computed by applying the statutory federal income tax rate to income (loss) 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.

In first quarter 2009, the Corporation applied an estimated annual effective tax rate to interim period pre-tax income (loss) to calculate the income tax provision (benefit) for the quarter, in accordance with the principal method prescribed by the accounting guidance established for computing income taxes in interim periods. The guidance allows for an alternative method to calculate the effective tax rate when an entity is unable to make a reliable estimate of pre-tax income (loss) for the fiscal year. Under the alternative method, interim period federal income taxes are based on each discrete quarter’s pre-tax income (loss). In light of the volatility and uncertainty in the economic market, the Corporation applied the alternative method to compute the income tax benefit beginning in the second quarter 2009.

At June 30, 2010, net unrecognized tax benefits were $5 million, compared to net unrecognized tax benefits of $23 million at June 30, 2009. The decrease in unrecognized tax benefits of $18 million for the six months ended June 30, 2010, when compared to the same period in the prior year, was primarily the result of the recognition of certain anticipated refunds due from the Internal Revenue Service (IRS), offset by the recognition of anticipated settlements with state tax authorities. The Corporation anticipates that it is reasonably possible that settlements of federal and state tax issues will result in a net unrecognized tax benefit of $3 million within the next twelve months. Accrued interest payable was $17 million and $37 million at June 30, 2010 and 2009, respectively. The decrease in accrued interest of $20 million for the six months ended June 30, 2010, when compared to the same period in the prior year, was primarily the

Table of Contents

Comerica Incorporated and Subsidiaries

Note 11 - Income Taxes and Tax-Related Items (continued)

result of the settlement of agreed items for certain years related to structured leasing transactions and the recognition of certain anticipated tax refunds from the IRS, offset by the recognition of anticipated settlements with state tax authorities. The amount of interest accrued at June 30, 2010 included interest for unrecognized tax benefits and interest payable to the IRS for tax positions that were settled, but not yet paid.

Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that current tax reserves are adequate to cover the matters outlined above, 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 or results of operations. Probabilities and outcomes are reviewed as events unfold, and adjustments to the reserves are made when necessary.

Net deferred tax assets were approximately $225 million at June 30, 2010. A valuation allowance is provided when it is “more-likely-than-not” that some portion of the deferred tax asset will not be realized. The valuation allowance of $1 million for certain state deferred tax assets was unchanged at June 30, 2010, compared to June 30, 2009. The Corporation determined that a valuation allowance was not needed against the federal deferred tax assets. Management’s determination was based on taxable income in the carry-back period, existing taxable temporary differences and anticipated future events.

Note 12 — Contingent Liabilities

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. In view of the inherent difficulty of predicting the outcome of such matters, the Corporation cannot state what the eventual outcome of these matters will be. However, 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. For information regarding income tax contingencies, refer to Note 11.

Note 13 — Business Segment Information

The Corporation has strategically aligned its operations into three major business segments: the Business Bank, the Retail Bank, and Wealth & Institutional Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. The Finance segment includes the Corporation’s securities portfolio and asset and liability management activities. This segment is responsible for managing the Corporation’s funding, liquidity and capital needs, performing interest sensitivity analysis and executing various strategies to manage the Corporation’s exposure to liquidity, interest rate risk, and foreign exchange risk. The Other category includes discontinued operations, the income and expense impact of equity and cash, tax benefits not assigned to specific business segments and miscellaneous other expenses of a corporate nature. 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, 2010. 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 24 to the consolidated financial statements in the Corporation’s 2009 Annual Report.

Note 14 —Discontinued Operations

In December 2006, the Corporation sold its ownership interest in Munder Capital Management (Munder), an investment advisory subsidiary, to an investor group. As part of the sale agreement, the Corporation received 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 periods ended June 30, 2010 and 2009 are shown in the following table. There was no income from discontinued operations for the three-month periods ended June 30, 2010 and 2009.

Common Stock Offering and Redemption of Preferred Stock

In the first quarter 2010, the Corporation fully redeemed $2.25 billion of Fixed Rate Cumulative Perpetual Preferred Stock (preferred stock) issued in connection with the U.S. Department of Treasury (U.S. Treasury) Capital Purchase Program. The redemption was funded by the net proceeds from an $880 million common stock offering completed in the first quarter 2010 and from excess liquidity at the parent company. The redemption resulted in a one-time, non-cash redemption charge of $94 million in the first quarter 2010, reflecting the accelerated accretion of the remaining discount, which reduced diluted earnings per common share by $0.57 for the six-month period ended June 30, 2010. The total impact of the preferred stock, including the redemption charge, cash dividends of $24 million and non-cash discount accretion of $5 million, was a reduction to diluted earnings per common share of $0.73 for the six-month period ended June 30, 2010. The only significant non-financial impact of the redemption was the removal of executive compensation rules by the U.S. Treasury. The executive and legislative branches of the federal government, as well as our primary regulators, may continue to request supplementary reporting.

In the second quarter 2010, the U.S. Treasury sold the related 11.5 million warrants, which grant the right to purchase an equal amount of shares of the Corporation’s common stock at $29.40 per share. The sale of the warrants by the U.S. Treasury had no impact on the Corporation’s equity. The warrants remained outstanding at June 30, 2010 and were included in “capital surplus” on the consolidated statements of changes in shareholders’ equity at their original fair value of $124 million.

Results of Operations

Net income for the three months ended June 30, 2010 was $70 million, an increase of $52 million from $18 million reported for the three months ended June 30, 2009. The increase in net income in the second quarter 2010 compared to the same period in 2009, was primarily due to a $182 million decrease in the provision for credit losses ($186 million decrease in the provision for loan losses, partially offset by a $4 million increase in the provision for credit losses on lending-related commitments), a $29 million decrease in Federal Deposit Insurance Corporation (FDIC) insurance expense, and a $20 million increase in net interest income, partially offset by a $112 decrease in net securities gains. Net income attributable to common stock was $69 million for the second quarter 2010, compared to a net loss attributable to common stock of $16 million for the same period one year ago. There were no preferred stock dividends included in net income attributable to common stock for the three months ended June 30, 2010, compared to $34 million of preferred stock dividends included in the net loss attributable to common stock for the same period one year ago. Diluted net income per common share was $0.39 in the second quarter 2010, compared to a diluted net loss per common share of $0.11 for the same period one year ago.

Net income for the first six months of 2010 was $122 million, an increase of $95 million from $27 million reported for the six months ended June 30, 2009. The increase in net income for the six months ended June 30, 2010 from the comparable 2009 period resulted primarily from a $202 million decrease in the provision for credit losses ($214 million decrease in the provision for loan losses, partially offset by a $12 million increase in the provision for credit losses on lending-related commitments), a $51 million increase in net interest income, decreases of $27 million in FDIC insurance expense and $19 million in employee benefits expense, and a $17 million after-tax gain recognized in “income from discontinued operations” in the first quarter 2010. These increases were partially offset by a $123 million decrease in net securities gains. The six-month period ended June 30, 2009 included a reduction of tax interest due to anticipated refunds due from the Internal Revenue Service (IRS) and a $24 million non-taxable gain on the termination of certain leveraged leases which, in addition to the impact of the increase in pre-tax income, resulted in a $78 million increase in the provision for income taxes in the six months ended June 30, 2010, compared to the comparable 2009 period. After preferred dividends of $123 million, the net loss applicable to common stock was $1 million for the first six months of 2010, compared to a net loss attributable to common stock of $40 million in the same period one year ago. The diluted net loss per common share, which included the non-cash redemption charge previously discussed, was $0.01 for the first six months of 2010, compared to a diluted net loss per common share of $0.27 for the comparable 2009 period.

2010 Outlook

For full-year 2010, management expects the following, based on an uncertain pace of economic recovery.

· Management expects loans to be stable from period-end June 30, 2010 to period-end December 31, 2010. Investment securities, excluding auction-rate securities, are expected to remain at a level similar to June 30, 2010.

· Based on excess liquidity remaining similar to June 30, 2010 through year-end 2010, management expects an average net interest margin between 3.20 percent and 3.30 percent for full-year 2010, reflecting the benefit, compared to 2009, from improved loan pricing and lower funding costs. No Federal Funds rate increase is assumed.

· Management expects net credit-related charge-offs between $600 million and $650 million for full-year 2010. The provision for credit losses is expected to be below net credit-related charge-offs.

· Management expects a low to mid single-digit decline in noninterest income compared to 2009, after excluding $243 million of 2009 net securities gains. Included in the outlook is an estimated $5 million negative impact on service charge income in the second half of 2010 from overdraft policy changes consistent with new regulations issued by the Federal Reserve.

· Management expects a low single-digit decrease in noninterest expenses compared to 2009.

· Management expects income tax expense to approximate 35 percent of income before income taxes less approximately $60 million of permanent differences related to low-income housing and bank-owned life insurance, partially offset by approximately $5 million of state adjustments.

Net Interest Income

Net interest income was $422 million for the three months ended June 30, 2010, an increase of $20 million compared to $402 million for the same period in 2009. The increase in net interest income in the second quarter 2010, compared to the same period in 2009, resulted primarily from changes in the funding mix, including a continued shift in funding sources toward lower-cost funds, maturities of higher-cost medium- and long-term debt and improved loan spreads. 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, 2010, compared to the same period in the prior year. On a FTE basis, net interest income increased $20 million to $424 million for the three months ended June 30, 2010, from $404 million for the comparable period in 2009. Average earning assets decreased $7.7 billion, or 13 percent, to $51.8 billion in the second quarter 2010, compared to $59.5 billion in the second quarter 2009, primarily due to a $7.0 billion, or 15 percent, decrease in average loans to $40.7 billion and a $2.5 billion decrease in investment securities available-for-sale, partially offset by an increase of $1.9 billion in average interest-bearing deposits with the Federal Reserve Bank (FRB). The net interest margin (FTE) for the three months ended June 30, 2010 increased 55 basis points to 3.28 percent, from 2.73 percent for the comparable period in 2009, primarily due to the reasons cited for the increase in net interest income discussed above. The net interest margin was reduced by approximately 23 basis points and eight basis points in the second quarters of 2010 and 2009, respectively, from excess liquidity. Excess liquidity was represented by $3.7 billion and $1.8 billion of average balances deposited with the FRB in the second quarters of 2010 and 2009, respectively, which resulted from strong core deposit growth and declining loans.

Net interest income was $837 million for the six months ended June 30, 2010, an increase of $51 million compared to $786 million for the same period in 2009. The increase in net interest income in the six months ended 2010, compared to the same period in 2009, 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 2010 on a FTE basis, compared to the same period in the prior year. On a FTE basis, net interest income for the six months ended June 30, 2010 was $840 million, compared to $790 million for the same period in 2009, an increase of $50 million. Average earning assets decreased $8.2 billion, or 14 percent, to $52.4 billion for the six months ended June 30, 2010, compared to $60.6 billion for the same period in the prior year, primarily due to a $7.6 billion, or 16 percent, decrease in average loans, to $41.0 billion, and a $2.6 billion decrease in investment securities available-for-sale, partially offset by an increase of $2.1 billion in average interest-bearing deposits with the FRB. The net interest margin (FTE) for the six months ended June 30, 2010 increased 60 basis points to 3.23 percent, from 2.63 percent for the same period in 2009, primarily due to the same reasons cited in the quarterly discussion above. The impact of excess liquidity, as defined above, was a reduction of approximately 24 basis points and seven basis points to the net interest margin (FTE) for the six-month periods ended June 30, 2010 and 2009, respectively. 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.

Based on excess liquidity remaining similar to June 30, 2010 through year-end 2010, management expects an average net interest margin between 3.20 percent and 3.30 percent for full-year 2010, reflecting the benefit, compared to 2009, from improved loan pricing and lower funding costs. No Federal Funds rate increase is assumed.

Excess liquidity, represented by average balances deposited with the FRB, reduced the net interest margin by 23 basis points and 8 basis points in the second quarter 2010 and 2009, respectively. Excluding excess liquidity, the net interest margin would have been 3.51% and 2.81% in each respective period.

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 $126 million for the second quarter 2010, compared to $312 million for the same period in 2009. The provision for loan losses for the first six months of 2010 was $301 million, compared to $515 million for the same period in 2009. 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 $186 million and $214 million in the provision for loan losses in the three- and six-month periods ended June 30, 2010, respectively, when compared to the same periods in 2009, resulted primarily from broad-based improvements in credit quality metrics. Improvements in credit quality metrics included a decline of $1.1 billion in the Corporation’s watch list loans - generally consistent with regulatory defined special mention, substandard and doubtful (nonaccrual) loans - from December 31, 2009 to June 30, 2010, compared to an increase of $1.7 billion in the same period in 2009. Additional indicators of improved credit quality included decreases in the rate of inflow to nonaccrual (based on an analysis of nonaccrual loans with book balances greater than $2 million) and in net credit-related charge-offs in the three- and six-month periods ended June 30, 2010, compared to the same periods in the prior year.

The national economy was recovering moderately from mid 2009 until the middle of the second quarter 2010, when economic indicators began showing signs of weaker but sustained growth. The initial recovery was spurred by the revival of credit and capital markets and massive monetary and budget stimulus. In early 2010, the private sector began to take the lead as reflected in renewed growth in private payrolls and notable strength in the manufacturing sector. The Michigan economy showed signs of recovering somewhat more slowly than the nation with strength concentrated in manufacturing. The average Michigan Business Activity Index for the first five months of 2010 increased 14 percent from the average for full-year 2009. The Michigan Business Activity index represents nine different measures of economic activity compiled by the Corporation. The California economy also appears to be lagging the national recovery. The housing sector showed signs of improvement, but ongoing budget problems continued to affect the recovery. The average California Economic Activity Index compiled by the Corporation for the first five months of 2010 increased three percent from the average for full-year 2009. The California Economic Activity Index equally weights nine, seasonally-adjusted, coincident measures of economic activity. Texas continued to outperform the national economy in 2010, with notable strength in manufacturing and energy exploration. Reflecting the broadening recovery in Texas, nonfarm payrolls increased at a three percent annual rate over the first five months of the year, slightly above one percent faster than nationally. Forward-looking indicators suggest that economic conditions in the Corporation’s primary geographic markets are likely to continue to strengthen gradually against a background of moderate national and global expansions.

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 2010 decreased $102 million to $146 million, or 1.44 percent of average total loans, compared to $248 million, or 2.08 percent for the second quarter 2009. The $102 million decrease in net loan charge-offs in the second quarter 2010, compared to the second quarter 2009, consisted primarily of decreases in net loan charge-offs in the Commercial Real Estate ($72 million) and Specialty Businesses ($29 million) business lines, partially offset by an increase in net loan charge-offs in the Middle Market ($19 million) business line. Middle Market net loan charge-offs totaled $71 million in the second quarter 2010, with $26 million attributed to a national specialty group which manages a $500 million loan portfolio which focuses on highly leveraged relationships. The $72 million decrease in net loan charge-offs in the Commercial Real Estate business line reflected decreases in all markets, with the exception of Texas, which experienced a nominal increase. By geographic market, the decrease in net loan charge-offs in the second quarter 2010, compared to the same period in 2009, consisted primarily of decreases in the Midwest ($48 million), Western ($23 million) and Florida ($16 million) markets.

Net loan charge-offs for the first six months of 2010 were $319 million, compared to $405 million for the same period in 2009. The $86 million decrease in net loan charge-offs for the first six months of 2010, compared to the same period in 2009, consisted primarily of decreases in net loan charge-offs in the Commercial Real Estate ($61 million), Specialty Businesses ($33 million) and Global Corporate Banking ($17 million) business lines, partially offset by an increase in the Middle Market ($26 million) business line. By geographic market, net loan charge-offs reflected decreases in net loan charge-offs in the Midwest ($48 million), Western ($34 million) and Florida ($18 million) markets, partially offset by an increase in net loan charge-offs in the Texas market ($14 million).

The provision for credit losses on lending-related commitments was less than $0.5 million and $7 million for the three- and six-month periods ended June 30, 2010, respectively, compared to negative provisions of $4 million and $5 million for the comparable periods in 2009. 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. The increases for the three- and six-month periods ended June 30, 2010, when compared to the same periods in 2009, resulted primarily from an increase in specific reserves related to standby letters of credit extended to customers in the Midwest market. There were less than $0.5 million in lending-related commitment charge-offs in the three- and six-month periods ended June 30, 2010 and 2009.

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 $600 million and $650 million for full-year 2010. The provision for credit losses is expected to be below net credit-related charge-offs.

Noninterest Income

Noninterest income was $194 million for the three months ended June 30, 2010, a decrease of $104 million, or 35 percent, compared to $298 million for the same period in 2009, resulting primarily from a $112 million decline in net securities gains and a $6 million second quarter 2009 gain on the sale of the Corporation’s proprietary defined contribution plan recordkeeping business, partially offset by a $16 million loss on the termination of leveraged leases in the second quarter 2009. Net securities gains in the second quarter 2009 included $109 million of gains on the sale of mortgage-backed government agency securities.

Noninterest income was $388 million for the first six months of 2010, a decrease of $133 million, or 26 percent, compared to the same period in 2009, due primarily to a $123 million decrease in net securities gains and $8 million of net gains from the termination of certain leveraged leases in the first six months of 2009. Net securities gains in the first six months of 2009 included $117 million of gains on the sale of mortgage-backed government agency securities.

In November 2009, the FRB issued a final rule under Regulation E which prohibits financial institutions from charging consumers fees for paying overdrafts on electronic transfers, including automated teller machine and debit card transactions, unless a consumer consents, or opts in, to the overdraft service for those types of transactions, effective in the third quarter 2010.

Management expects a low to mid single-digit decline in noninterest income for full-year 2010 compared to 2009, after excluding $243 million of 2009 net securities gains. Included in the outlook is an estimated $5 million negative impact on service charge income in the second half of 2010 from overdraft policy changes consistent with new regulations issued by the Federal Reserve.

Noninterest Expenses

Noninterest expenses were $397 million for the three months ended June 30, 2010, a decrease of $32 million, or seven percent, from $429 million for the comparable period in 2009. The decrease in noninterest expenses resulted primarily from decreases in FDIC insurance expense ($29 million), due to the 2009 industry-wide special assessment charge, and employee benefits expense ($8 million), resulting primarily from a decline in defined benefit pension expense ($6 million), partially offset by an increase in salaries expense ($8 million) as a result of annual merit increases and increased share-based compensation expense. The number of full-time equivalent employees declined by approximately 400, or four percent, from June 30, 2009 to June 30, 2010.

Noninterest expenses were $801 million for the first six months of 2010, a decrease of $25 million, or three percent, compared to $826 million for the comparable period in 2009. The decrease in noninterest expense resulted primarily from decreases in FDIC insurance expense ($27 million) and employee benefits expense ($19 million), resulting primarily from a decline in defined benefit pension expense ($17 million), partially offset by increases in the provision for credit losses on lending-related commitments ($12 million) and salaries expense ($6 million).

The following table summarizes the various components of salaries and employee benefits expense.

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

Total employee benefits	45		53		89		108
Total salaries and employee benefits	$	224	$	224	$	437	$	450

Management expects a low single-digit decrease in noninterest expenses for full-year 2010 compared to 2009.

Provision for Income Taxes

The provision for income taxes for the second quarter 2010 was $23 million, compared to a benefit of $59 million for the same period in 2009. For the six months ended June 30, 2010, the provision for income taxes was $18 million, compared to a benefit of $60 million for the same period in 2009.

In the second quarter 2009, the Corporation elected to change the accounting method used to calculate interim period federal income taxes from an estimated annual effective tax rate method to a method which determines taxes based on each discrete quarter’s pre-tax income. The change in method resulted in an increase of approximately $20 million to the income tax benefit recorded in the second quarter 2009, which represented the adjustment necessary to conform the first quarter 2009 tax provision to the new methodology. The $78 million increase in the provision for income taxes in the six-month period ended June 30, 2010, compared to the same period in the prior year, reflected an increase in income before income taxes, the reduction of tax interest in 2009 due to anticipated refunds due from the Internal Revenue Service (IRS) and a first quarter 2009 $24 million non-taxable gain on the termination of certain leveraged leases. The $82 million increase in the provision for income taxes in the three-month period ended June 30, 2010, compared to the comparable prior year period, reflected the impact of the change in the method of calculating interim period federal income taxes in addition to the items noted above. For further information on income taxes, refer to Note 11 to these unaudited consolidated financial statements.

Table of Contents

Net deferred tax assets were $225 million at June 30, 2010, compared to $158 million at December 31, 2009, an increase of $67 million, primarily due to a reduction in deferred tax liabilities resulting from payments made to the IRS in 2010 for structured leasing transactions, partially offset by increased deferred tax liabilities resulting from unrealized gains recognized in other comprehensive income at June 30, 2010. A valuation allowance is provided when it is “more-likely-than-not” that some portion of the deferred tax asset will not be realized. The valuation allowance of $1 million for certain state deferred tax assets was unchanged at June 30, 2010, compared to December 31, 2009. The Corporation determined that a valuation allowance was not needed against the federal deferred tax assets. Management’s determination was based on taxable income in the carry-back period, existing taxable temporary differences and anticipated future events.

Management expects income tax expense for full-year 2010 to approximate 35 percent of income before income taxes less approximately $60 million of permanent differences related to low-income housing and bank-owned life insurance, partially offset by approximately $5 million of state adjustments.

Income from Discontinued Operations, Net of Tax

Income from discontinued operations, net of tax, was $17 million for the first six months of 2010, compared to $1 million for the same period in the prior year. The $16 million increase in the first six months of 2010, when compared to the same period in the prior year, resulted from $17 million after-tax gain in the first quarter 2010 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 14 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 & Institutional 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 13 to these unaudited consolidated financial statements presents financial results of these business segments for the six months ended June 30, 2010 and 2009. For a description of the business activities of each business segment and the methodologies which form the basis for these results, refer to Note 13 to these unaudited consolidated financial statements and Note 24 to the consolidated financial statements in the Corporation’s 2009 Annual Report.

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

The Business Bank’s net income of $223 million increased $161 million for the six months ended June 30, 2010, compared to the six months ended June 30, 2009. Net interest income (FTE) was $692 million, an increase of $52 million from the comparable prior year period. The increase in net interest income (FTE) was primarily due to an increase in loan and deposit spreads and the benefit provided by a $4.0 billion increase in average deposits, partially offset by a $7.0 billion decrease in average loans. The provision for loan losses of $219 million decreased $210 million from the comparable period in the prior year, primarily due to a reduction in reserves for Commercial Real Estate (with decreases in all markets, except Texas) and Global Corporate Banking (primarily in the Western market) business lines. Net credit-related charge-offs of $251 million decreased $83 million from the comparable period in the prior year, primarily due to decreases in charge-offs in the Commercial Real Estate, Specialty Businesses and Global Corporate Banking business line, partially offset by an increase in the Middle Market

Table of Contents

business line. Noninterest income of $152 million increased $10 million from the comparable prior year period, primarily due to increases in commercial lending fees ($7 million), letter of credit fees ($5 million) and foreign exchange income ($4 million), partially offset by an $8 million 2009 gain on the termination of certain leveraged leases. Noninterest expenses of $319 million increased $6 million from the same period in the prior year, primarily due to increases in allocated corporate overhead expenses ($11 million) and the provision for credit losses on lending-related commitments ($6 million), partially offset by decreases in FDIC insurance expense ($5 million), due primarily to the 2009 industry-wide special assessment charge, employee benefits expense ($3 million) and nominal decreases in other noninterest expense categories.

The net loss for the Retail Bank was $10 million for the six months ended June 30, 2010, compared to a net loss of $26 million for the six months ended June 30, 2009. Net interest income (FTE) of $265 million increased $12 million from the comparable period in the prior year, primarily due to an increase in loan and deposit spreads, partially offset by decreases in both average deposits ($704 million) and average loans ($677 million). The provision for loan losses decreased $13 million from the comparable period in the prior year, due to decreases in reserves in the Personal Banking and Small Business Banking business lines. Noninterest income of $86 million decreased $7 million from the comparable prior year period, primarily due to a $4 million decline in service charges on deposits. Noninterest expenses of $314 million decreased $14 million from the same period in the prior year, primarily due to decreases in FDIC insurance expense ($10 million), due primarily to the 2009 industry-wide special assessment charge, and employee benefit expense ($4 million), partially offset by an increase in allocated net corporate overhead expenses ($5 million).

Wealth & Institutional Management’s net income of $16 million decreased $12 million for the six months ended June 30, 2010, compared to the six months ended June 30, 2009. Net interest income (FTE) of $87 million increased $10 million from the comparable period in the prior year, primarily due to the benefit provided by an increase in average deposits ($344 million) and increases in loan and deposit spreads. The provision for loan losses increased $8 million from the comparable period in the prior year, primarily due to an increase in reserves in the Private Banking business line, primarily in the Florida market. Noninterest income of $122 million decreased $21 million from the comparable period in the prior year, primarily due to decreases in fiduciary income ($6 million), due primarily to the 2009 sale of the Corporation’s proprietary defined contribution plan recordkeeping business, brokerage fees ($5 million) and a 2009 gain related to the sale of the defined contribution plan recordkeeping business ($6 million).

The net loss for the Finance Division was $116 million for the six months ended June 30, 2010, compared to a net loss of $42 million for the six months ended June 30, 2009. Contributing to the $74 million increase in net loss was a $10 million increase in net interest expense (FTE), primarily due to the Corporation’s internal funds transfer policy. In the current low-rate environment, the Finance Division provided a greater benefit for deposits, particularly noninterest-bearing deposits, to the three major business segments in the first six months of 2010 than was actually realized at the corporate level. Noninterest income decreased $117 million from the comparable period in the prior year, primarily due to a decline in net securities gains. Noninterest expenses decreased $8 million from the comparable period in the prior year, primarily due to a decline in FDIC insurance ($7 million), due primarily to the 2009 industry-wide special assessment charge.

The Other category’s net income was $9 million for the six months ended June 30, 2010, compared to $5 million for the six months ended June 30, 2009. The $4 million increase in net income reflected a $17 million after-tax discontinued operations gain recognized in the first quarter 2010, partially offset by timing differences between when corporate expenses are reflected as a consolidated expense and when the expenses are allocated to the business segments.

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 13 to these unaudited consolidated financial statements contains a description and presents financial results of these market segments for the six months ended June 30, 2010 and 2009.

The Midwest market’s net income increased $52 million for the six months ended June 30, 2010, compared to the six months ended June 30, 2009. Net interest income (FTE) of $418 million increased $24 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 $609 million increase in average deposits, partially offset by a $2.7 billion decrease in average loans. The provision for loan losses decreased $80 million, primarily due to a reduction in reserves for the Middle Market and Specialty Businesses business lines. Net credit-related charge-offs of $105 million decreased $48 million from the comparable period in the prior year, primarily due to decreases in charge-offs in the Specialty Businesses and Commercial Real Estate business lines. Noninterest income of $199 million decreased $22 million from the comparable period in the prior year, primarily due to an $8 million 2009 gain on the termination of certain leveraged leases, and decreases in fiduciary income ($6 million), service charges on deposit accounts ($4 million) and brokerage fees ($3 million). Noninterest expenses of $368 million decreased $12 million from the same period in the prior year, primarily due to decreases in salaries and employee benefits expense ($11 million), FDIC insurance ($9 million), due primarily to the 2009 industry-wide special assessment charge, and smaller decreases in several other noninterest expense categories, partially offset by an increase in the provision for credit losses on lending-related commitments ($7 million) and allocated net corporate overhead expenses ($7 million).

The Western market recorded net income of $61 million for the six months ended June 30, 2010, compared to a net loss of $14 million for the six months ended June 30, 2009. Net interest income (FTE) of $325 million increased $24 million from the comparable prior year period, primarily due to an increase in loan and deposit spreads and the benefit provided by a $1.3 billion increase in average deposits, partially offset by a $2.1 billion decline in average loans. The provision for loan losses decreased $92 million, primarily due to a reduction in reserves in the Global Corporate Banking and Commercial Real Estate (primarily residential real estate developers in California) business lines. Net credit-related charge-offs of $112 million decreased $34 million from the comparable period in the prior year, primarily due to decreases in charge-offs in the Commercial Real Estate and Global Corporate Banking business lines. Noninterest expenses of $215 million decreased $2 million from the same period in the prior year, primarily due to a $5 million decrease in FDIC insurance, due primarily to the 2009 industry-wide special assessment charge, and nominal decreases in other noninterest expense categories, partially offset by a $6 million increase in allocated net corporate overhead expenses.

The Texas market’s net income increased $21 million to $40 million for the six months ended June 30, 2010, compared to the six months ended June 30, 2009. Net interest income (FTE) of $160 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 an increase of $789 million in average deposits, partially offset by a $1.1 billion decline in average loans. The provision for loan losses decreased $20 million, largely due to decreases in reserves for the Middle Market and Specialty Businesses business lines, partially offset by an increase in the Commercial Real Estate business line. Net credit-related charge-offs of $33 million increased $14 million from the comparable period in the prior year, primarily due to an increase in charge-offs in the Commercial Real Estate business line. Noninterest expenses of $125 million increased $6 million from the comparable period in the prior year, primarily due to an increase in allocated net corporate overhead expenses ($4 million).

The net loss for the Florida market was $8 million for the six months ended June 30, 2010, compared to a net loss of $14 million for the six months ended June 30, 2009. Net interest income (FTE) of $21 million was largely unchanged from the comparable period in the prior year. The provision for loan losses decreased $16 million, primarily due to a reduction in reserves in the Commercial Real Estate and Middle Market business lines, partially offset by an increase in reserves in the Private Banking business line.

The Other Markets’ net income decreased $4 million to $24 million for the six months ended June 30, 2010, compared to the six months ended June 30, 2009. Net interest income (FTE) of $83 million increased $4 million from the comparable period in the prior year, primarily due to increases in loan and deposit spreads and the benefit provided by a $613 million increase in average deposits, partially offset by a $991 million decrease in average loans. The provision for loan losses increased $9 million, primarily due to an increase in reserves for the Middle Market business line, partially offset by a reduction in reserves for the Commercial Real Estate and Global Corporate Banking business lines.

The International market’s net income increased $15 million to $30 million for the six months ended June 30, 2010, compared to the six months ended June 30, 2009. Net interest income (FTE) of $37 million increased $6 million from the comparable period in the prior year, primarily due to an increase in loan spreads, partially offset by a $454 million decrease in average loans. The provision for loan losses was a negative provision of $8 million for the six months ended June 30, 2010, compared to a charge of $8 million for the same period in 2009.

The net loss for Finance & Other Businesses was $107 million for the six months ended June 30, 2010, compared to a net loss of $37 million for the six months ended June 30, 2009. The $70 million increase in net loss was due to the same reasons noted in the Finance Division and Other category discussions under the “Business Segments” heading above.

Financial Condition

Total assets were $55.9 billion at June 30, 2010, compared to $59.2 billion at December 31, 2009 and $63.6 billion at June 30, 2009. Total loans decreased $1.6 billion, or four percent, to $40.6 billion at June 30, 2010 compared to December 31, 2009. On an average basis, total assets decreased $2.1 billion in the second quarter 2010, compared to the fourth quarter 2009, resulting primarily from a decrease in average total loans of $2.1 billion, or five percent, to $40.7 billion and a decrease in average investment securities available-for-sale of $1.3 billion, primarily due to the fourth quarter 2009 sales of mortgage-backed government agency securities, partially offset by an increase in average interest-bearing deposits with the FRB ($1.3 billion). The decline in average total loans reflected subdued demand from customers in an uncertain economic environment.

N/M - not meaningful

While average loan outstandings declined in the second quarter 2010, the pace of decline continued to slow and the Corporation was encouraged by growth in unfunded loans in the underwriting process.

Management expects loans to be stable from period-end June 30, 2010 to period-end December 31, 2010. Investment securities, excluding auction-rate securities, are expected to remain at a level similar to June 30, 2010 for the remainder of 2010.

Total liabilities decreased $2.1 billion, or four percent, to $50.1 billion at June 30, 2010, compared to $52.2 billion at December 31, 2009. Total deposits increased $115 million, or less than one percent, to $39.8 billion at June 30, 2010 compared to December 31, 2009. Core deposits, which exclude other time deposits and foreign office time deposits, increased $1.1 billion, or three percent, from December 31, 2009 to June 30, 2010. Other time deposits decreased $882 million to $165 million at June 30, 2010, compared to December 31, 2009, primarily due to the maturity of retail brokered certificates of deposit. Medium- and long-term debt decreased $2.0 billion to $9.0 billion at June 30, 2010, compared to December 31, 2009, primarily as a result of the maturity of $1.0 billion of Federal Home Loan Bank advances and $950 million of medium-term notes during the period. On an average basis, deposits increased $886 million in the second quarter 2010, compared to the fourth quarter 2009, resulting primarily from an increase in core deposits of $2.2 billion, or six percent, to $38.9 billion.

In April 2010, the FDIC adopted an interim rule extending the Transaction Account Guarantee Program (TAGP) through December 31, 2010 for financial institutions that desire to continue TAGP participation. The Corporation notified the FDIC of its decision to opt-out of the FDIC’s TAGP extension, effective July 1, 2010. In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Financial Reform Act”) reinstated, for all financial institutions, unlimited deposit insurance on noninterest-bearing accounts for the period from December 31, 2010 through December 31, 2012. For further discussion of the Financial Reform Act, refer to “The Dodd-Frank Wall Street Reform and Consumer Protection Act” section of this financial review.

Capital

Total shareholders’ equity decreased $1.2 billion to $5.8 billion at June 30, 2010, compared to December 31, 2009, resulting primarily from the first quarter 2010 full redemption of $2.25 billion of preferred stock issued to the U.S. Treasury, partially funded by the net proceeds from an $880 million common stock offering completed in the first quarter 2010.

In the second quarter 2010, the U.S. Treasury sold the related 11.5 million warrants, which granted the right to purchase an equal amount of shares of the Corporation’s common stock at $29.40 per share. The sale of the warrants by the U.S. Treasury had no impact on the Corporation’s equity. The warrants remained outstanding at June 30, 2010 and were included in “capital surplus” on the consolidated statements of changes in shareholders’ equity at their original fair value of $124 million.

The following table presents a summary of changes in total shareholders’ equity for the six months ended June 30, 2010.

In November 2007, the Board of Directors of the Corporation authorized the purchase up to 10 million shares of Comerica Incorporated outstanding common stock, in addition to the remaining unfilled portion of the November 2006 authorization. There is no expiration date for the Corporation’s share repurchase program. As shown in the following table, which summarizes the Corporation’s share repurchase activity, there were no shares purchased as part of the Corporation’s publicly announced repurchase program during the six months ended June 30, 2010.

Table of Contents

Risk-based regulatory capital standards are designed to make regulatory capital requirements more sensitive to differences in credit risk profiles among bank holding companies 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 tangible common equity and Tier 1 common capital ratios increased primarily due to the common stock offering completed in the first quarter 2010. The Tier 1 and total risk-based capital ratios reflect the full redemption of preferred stock, partially offset by the common stock issuance discussed above.

In July 2010, the Financial Reform Act was signed into law, which prohibits holding companies with more than $15 billion in assets from including trust preferred securities in Tier 1 capital, with a phase-in period of three years, beginning on January 1, 2013. At June 30, 2010, the Corporation had $500 million of trust preferred securities outstanding that added an estimated 82 basis points to the Corporation’s Tier 1 capital ratio. For further discussion of the Financial Reform Act, refer to “The Dodd-Frank Wall Street Reform and Consumer Protection Act” section of this financial review.

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

(a)	See Supplemental Financial Data section for reconcilements of non-GAAP financial measures.
(b)	June 30, 2010 capital and ratios are estimated.

At June 30, 2010, 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 38-59 in the Corporation’s 2009 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 homogeneous pools of loans with similar risk characteristics for the remaining business, consumer and residential mortgage loans. The Corporation defines business loans as those belonging to the commercial, real estate construction, commercial mortgage, lease financing and international loan portfolios.

A loan is considered impaired when it is probable that interest or principal payments will not be made in accordance with the contractual terms of the original loan agreement. The Corporation performs a detailed credit quality review quarterly on large impaired business and certain large impaired consumer and residential mortgage loans and establishes a specific allowance for such loans, estimated using one of several methods, including the estimated fair value of underlying collateral, observable market value of similar debt or discounted expected future cash flows.

Table of Contents

Independent third-party appraisals are obtained prior to the origination of any first mortgage loan. “As developed” collateral values are used at the time of origination of a construction loan, on the assumption that the construction facility provides sufficient funds to complete the project and carry it until it is leased or sold. Credit reviews are performed at least annually on each collateral-dependent loan and, if necessary, adjustments to the original appraisals are made to reflect the most current risk profile of the project. These adjustments may include a revised rental rate or absorption rate, based on the actual conditions at that time. Updated independent third-party appraisals are generally obtained at the time of a refinance or restructure where additional advances are requested or when there is evidence that the physical aspects of the property have deteriorated.

For collateral-dependent impaired loans, updated appraisals are obtained at least annually unless conditions dictate increased frequency. Appraisals on impaired construction loans are generally based on “as is” collateral values. In certain circumstances, the Corporation may believe that the highest and best use of the collateral, and thus the most advantageous exit strategy, requires completion of the construction project. In these situations, the Corporation uses an “as-developed” appraisal to evaluate alternatives. However, the “as-developed” collateral value is appropriately adjusted to reflect the cost to complete the construction project and to prepare the property for sale. Between appraisals the Corporation may reduce the collateral value based upon the age of the appraisal and adverse developments in market conditions.

Loans which do not meet the criteria to be evaluated individually are evaluated in homogeneous pools of loans with similar risk characteristics. The allowance for all other business loans is determined by applying standard reserve factors to the pool of business loans within each internal risk rating. Internal risk ratings are assigned to each business loan at the time of approval and are subjected to subsequent periodic reviews by the Corporation’s senior management. Standard reserve factors for the loans within each risk rating are updated quarterly and are based on estimated probabilities of default and loss given default, incorporating factors such as recent charge-off experience, current economic conditions and trends, changes in collateral values of properties securing loans, and trends with respect to past due and nonaccrual amounts. The standard reserve factors are supported by underlying analysis, including information on migration and loss given default studies from each of the three largest domestic geographic markets (Midwest, Western and Texas), as well as mapping to publicly available debt ratings. Incremental reserves may be established to cover losses in industries and/or portfolios experiencing elevated loss levels. On a limited basis, the Corporation uses data annually from Standard & Poor’s (S&P) publicly available debt ratings to determine the level of probability of default for loans that are considered to have strong credit quality and are assigned the best internal risk ratings. To ensure the use of probability of default based on S&P debt ratings is appropriate, the Corporation compares the assigned internal risk ratings of borrowers that have public debt outstanding to their publicly available S&P debt rating for consistency. The Corporation has sufficient default experience and is able to generate its own probability of default metrics on the remainder of the loan portfolio. The Corporation uses its own loss given default experience to determine the overall expected loss measure.

The allowance for all other consumer and residential mortgage loans is determined by applying estimated loss rates to various pools of loans within the portfolios with similar risk characteristics. Estimated loss rates for all pools are updated quarterly, incorporating factors such as recent charge-off experience, current economic conditions and trends, changes in collateral values of properties securing loans (using index-based estimates), and trends with respect to past due and nonaccrual amounts.

Actual losses experienced in the future may vary from those estimated. The uncertainty occurs because factors may exist which affect the determination of probable losses inherent in the loan portfolio and are not necessarily captured by the application of standard reserve factors or identified industry-specific risks. An additional allowance is established to capture these probable losses and reflects management’s view that the allowance should recognize the margin for error inherent in the process of estimating expected loan losses. Factors that were considered in the evaluation of the adequacy of the Corporation’s allowance for loan losses included the inherent imprecision in the risk rating system resulting from inaccuracy in assigning risk ratings or stale ratings which may not have been updated for recent negative trends in particular credits. Risk ratings on business loan relationships meeting an internally specified exposure threshold are updated annually or more frequently upon the occurrence of a circumstance that affects the credit risk of the relationship.

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 in countries where the Corporation has loans, 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

Table of Contents

$967 million at June 30, 2010, compared to $985 million at December 31, 2009, a decrease of $18 million, or two percent. The decrease resulted primarily from broad-based improvements in credit quality metrics including a decline of $1.1 billion in the Corporation’s watch list loans - generally consistent with regulatory defined special mention, substandard and doubtful (nonaccrual) loans - from December 31, 2009 to June 30, 2010. The decreases in the allowance for loan losses consisted of decreases in the Commercial Real Estate (primarily the Western and Texas markets) and Global Corporate Banking business lines, partially offset by an increase in specific and incremental allowances for the Middle Market business line (primarily Other Markets and the Western market). The allowance for loan losses as a percentage of total period-end loans was 2.38 percent at June 30, 2010, compared to 2.34 percent at December 31, 2009. Nonperforming loans of $1.1 billion at June 30, 2010 decreased $60 million, or five percent, compared to $1.2 billion at December 31, 2009. As noted above, 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. 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, 2010, nonperforming loans were charged-off to 55 percent of the contractual amount, compared to 56 percent at December 31, 2009. This level of write-downs is consistent with losses experienced on defaulted loans in the first six months of 2010 and in recent years. The allowance as a percentage of total nonperforming loans, a ratio which results from the actions noted above, was 86 percent at June 30, 2010, compared to 83 percent at December 31, 2009. The Corporation’s loan portfolio is heavily composed of business loans, which, in the event of default, are typically carried on the books at fair value as nonperforming assets for a longer period of time than are consumer loans, which are generally fully charged off when they become nonperforming, resulting in a lower nonperforming loan allowance coverage.

The allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, provides for probable credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. Allowances for lending-related commitments for which it is probable that the commitment will be drawn (or sold) are estimated using the same methods as business loans. In general, the probability of draw for letters of credit is considered certain once the credit is assigned an internal risk rating generally consistent with regulatory defined substandard or doubtful. Other letters of credit, all unfunded commitments and financial guarantees have a lower probability of draw, to which standard loan loss rates are applied.

The allowance for credit losses on lending-related commitments was $44 million at June 30, 2010, an increase of $7 million from $37 million at December 31, 2009. The increase resulted primarily from an increase in specific reserves related to standby letters of credit extended to customers in the Midwest market.

Table of Contents

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 $13.1 billion at June 30, 2010, of which $4.3 billion, or 33 percent, were to borrowers in the Commercial Real Estate business line, which includes loans to residential real estate investors and developers. The remaining $8.8 billion, or 67 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 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 development outstandings of $828 million at June 30, 2010 decreased $234 million, or 22 percent, from $1.1 billion at December 31, 2009. Net credit-related charge-offs in the Commercial Real Estate business line totaled $121 million for the first six months of 2010, including $52 million in the Western market (residential real estate development business), $26 million in the Midwest market and $24 million in the Texas market.

Table of Contents

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 $2.3 billion of real estate construction loans in the Commercial Real Estate business line, $385 million were on nonaccrual status at June 30, 2010, including single family projects totaling $146 million (primarily in the Western and Florida markets) and residential land development projects totaling $109 million (primarily in the Western and Texas markets). Real estate construction loan net charge-offs in the Commercial Real Estate business line totaled $93 million for the six months ended June 30, 2010, including $36 million from single family projects (primarily the Western, Other Markets and Florida markets), $20 million from multi-use projects (primarily the Texas and Western markets) and $18 million from residential land development projects (primarily the Texas market).

The commercial mortgage loan portfolio totaled $10.3 billion at June 30, 2010 and included $8.3 billion of primarily owner-occupied commercial mortgage loans. Commercial mortgage loans in the Commercial Real Estate business line totaled $2.0 billion and included $135 million of nonaccrual loans at June 30, 2010, which consisted primarily of residential land carry, single family and nonresidential land carry projects ($41 million, $32 million and $30 million, respectively). Commercial mortgage loan net charge-offs in the Commercial Real Estate business line totaled $28 million for the six months ended June 30, 2010, primarily from residential land carry and multi-family projects ($10 million and $7 million, respectively).

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, totaled $3.4 billion at June 30, 2010. Residential mortgages totaled $1.6 billion at June 30, 2010, and were primarily larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.6 billion of residential mortgage loans outstanding, $53 million were on nonaccrual status at June 30, 2010. The home equity portfolio totaled $1.8 billion at June 30, 2010, of which $1.6 billion was outstanding under primarily variable-rate, interest-only home equity lines of credit and $234 million consisted of closed-end home equity loans. Of the $1.8 billion of home equity loans outstanding, $6 million were on nonaccrual status at June 30, 2010. A substantial majority of the home equity portfolio was secured by junior liens.

The following table summarizes the Corporation’s residential mortgage and home equity loan portfolio by geographic market as of June 30, 2010.

Table of Contents

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. 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, 2010, the Corporation estimated that, of the $17 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 by regulatory authorities at the agent bank level. The Corporation generally seeks to obtain ancillary business at the origination of a SNC relationship. Loans classified as SNC loans (approximately 1,000 borrowers at June 30, 2010) totaled $7.7 billion at June 30, 2010, a decline of $1.4 billion from $9.1 billion at December 31, 2009. SNC net loan charge-offs totaled $22 million and $62 million for the three- and six-month periods ended June 30, 2010, respectively. Nonaccrual SNC loans decreased $51 million to $243 million during the six months ended June 30, 2010, from $294 million at December 31, 2009. SNC loans, diversified by both business line and geographic market, comprised approximately 19 percent and 20 percent of total loans at June 30, 2010 and December 31, 2009, respectively. SNC loans are held to the same credit underwriting standards as the remainder of the loan portfolio and face similar credit challenges, primarily driven by residential real estate development.

Automotive Lending

Loans to borrowers involved with automotive production totaled approximately $906 million at June 30, 2010, compared to $941 million at December 31, 2009. Loans in the National Dealer Services business line totaled $3.6 billion and $3.3 billion at June 30, 2010 and December 31, 2009, respectively. Of the $3.6 billion of outstanding loans in the National Dealer Services business line at June 30, 2010, approximately $2.3 billion, or 63 percent, were to foreign franchises, $814 million, or 23 percent, were to domestic franchises and $504 million, or 14 percent, were to other. Other dealer loans include obligations where a primary franchise was indeterminable, such as loans to large public dealership consolidators and rental car, leasing, heavy truck and recreation vehicle companies.

Market 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 commercial loans funded by a combination of core deposits and wholesale borrowings. 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 without 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 gradually increase and decrease rates approximately 200 basis points in a linear fashion from the base case over twelve months (but decrease to no lower than zero percent). 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, while the rising interest rate scenario reflects a gradual 200 basis point rise. 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 rate, 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, 2010 and December 31, 2009, displays the estimated impact on net interest income during the next 12 months by relating the base case scenario results to those from the rising and declining rate scenarios described above. The sensitivity from December 31, 2009 to June 30, 2010 was essentially unchanged, as changes in funding mix offset the impact from the first quarter 2010 full redemption of $2.25 billion of preferred stock issued to the U.S. Treasury.

- 25 basis points (to zero percent)	(13		)	(1	)	(13		)	(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 mark-to-market valuation of the Corporation’s balance sheet and then applies the estimated impact of rate movements to the market 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.

Table of Contents

The table below, as of June 30, 2010 and December 31, 2009, displays the estimated impact on the economic value of equity from a 200 basis point immediate parallel increase or decrease in interest rates (but decrease to no lower than zero percent). 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, 2009 and June 30, 2010 was primarily driven by changes in the Corporation’s mortgage-backed securities portfolio mix and forecasted prepayments, which modestly reduce balance sheet sensitivity to rising rates.

Wholesale Funding

The Corporation satisfies liquidity requirements with either liquid assets or various funding sources. At June 30, 2010, the Corporation held excess liquidity, represented by $3.3 billion deposited with the FRB. 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 $849 million at June 30, 2010, compared to $2.1 billion at December 31, 2009. Capacity for incremental purchased funds at June 30, 2010, 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, 2010, the Corporation had $5.0 billion of outstanding borrowings from the FHLB with remaining maturities ranging from 3 months to 4 years. Another source of funding, if needed, would be liquid assets, which totaled $7.5 billion at June 30, 2010, compared to $7.7 billion at December 31, 2009, including cash and due from banks, federal funds sold and securities purchased under agreements to resell, interest-bearing deposits with the FRB and other banks, other short-term investments and unencumbered investment securities available-for-sale. Additionally, the Corporation could issue up to $13.8 billion of debt at June 30, 2010 under an existing $15 billion medium-term senior note program which allows its principal banking subsidiary to issue debt with maturities between one 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, 2010, the Corporation had a $55 million portfolio of investments in indirect private equity and venture capital funds, with commitments of $23 million to fund additional investments in future periods. The value of these investments is at risk to changes in equity markets, general economic conditions and a variety of other factors. The majority of these investments are not readily marketable and are included in “accrued income and other assets” on the consolidated balance sheets. The investments are individually reviewed for impairment on a quarterly basis by comparing the carrying value to the estimated fair value.

For further discussion of market risk, see Note 5 to these unaudited consolidated financial statements and pages 52-59 in the Corporation’s 2009 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.

· TAG Extension: Provides unlimited deposit insurance on noninterest-bearing accounts from December 31, 2010 to December 31, 2012. Assuming the same assessment rate as the current program, applied to first quarter 2010 deposit levels, the estimated annual cost is approximately $14 million.

· 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. Assuming no change to the current assessment rate, applied to first quarter 2010 net assets, the estimated increase in annual FDIC fees is approximately $17 million.

· 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 estimates).

· Interchange Fee: Limits debit card transaction processing fees that card issuers can charge to merchants. Current estimated annual revenue, based on full-year 2010 estimates, from debit card PIN and signature-based interchange fees of $7 million and $31 million, respectively, could decrease.

· 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 on January 1, 2013. At June 30, 2010, the Corporation had $500 million of trust preferred securities outstanding that added an estimated 82 basis points to the Corporation’s Tier 1 capital ratio.

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 2009 Annual Report, as updated in Note 1 to these unaudited consolidated financial statements. 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, 2009, the most critical of these significant accounting policies were the policies related to allowance for credit losses, valuation methodologies, 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 60-65 in the Corporation’s 2009 Annual Report.

As discussed above, the Financial Reform Act is expected to impact certain fee categories, including fees in the Corporation’s Retail Bank business segment. The ultimate impact of the Financial Reform Act is subject to interpretation and will remain uncertain until final rulemaking is complete. Given the uncertainty of the timing and scope of the estimated impact, the Corporation has concluded that the accounting policy related to goodwill requires classification as a critical accounting policy, effective July, 2010. There have been no events since the annual test performed in the third quarter 2009 that would indicate that it is more likely than not that goodwill had become impaired.

Table of Contents

Below is the additional critical accounting policy for goodwill reflecting the results of the most recent annual test performed as of the third quarter 2009. As of the date of this report, the Corporation does not believe there are any other material changes in the nature or categories of the critical accounting policies or estimates and assumptions from those discussed in the Corporation’s 2009 Annual Report.

Goodwill

Goodwill is the value attributed to unidentifiable intangible elements in acquired businesses. Goodwill is initially recorded at fair value and is subsequently evaluated at least annually for impairment. The Corporation conducts its evaluation of goodwill impairment in the third quarter each year and on an interim basis if events or changes in circumstances between annual tests indicate the assets might be impaired. Goodwill impairment testing is performed at the reporting unit level, equivalent to a business segment or one level below.

The goodwill impairment test is a two-step test. The first step of the goodwill impairment test compares the estimated fair value of the Corporation’s identified reporting units with their carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying value, goodwill of the reporting unit is not impaired. If the estimated fair value of the reporting unit is less than the carrying value, the second step must be performed to determine the implied fair value of the reporting unit’s goodwill and the amount of goodwill impairment, if any.

Estimating the fair value of reporting units is a subjective process involving the use of estimates and judgments, particularly related to future cash flows of the reporting units, discount rates (including market risk premiums) and market multiples. The fair values of the reporting units were determined using a blend of two commonly used valuation techniques, the market approach and the income approach. The Corporation gives consideration to both valuation techniques, as either technique can be an indicator of value. For the market approach, valuations of reporting units were based on an analysis of relevant price multiples in market trades in industries similar to the reporting unit. Market trades do not consider a control premium associated with an acquisition or a sale transaction. For the income approach, estimated future cash flows and terminal value (value at the end of the cash flow period, based on price multiples) were discounted. The discount rate was based on the imputed cost of equity capital appropriate for each reporting unit. Material assumptions used in the valuation models included the comparable public company price multiples used in the terminal value, future cash flows and the market risk premium component of the discount rate. Due to the general uncertainty and depressed earning capacity in the financial services industry as of the measurement date, the Corporation concluded that the valuation under the income approach more clearly reflected the long-term future earning capacity of the reporting units, rather than the valuation under the market approach, and thus gave greater weight to the income approach.

Four reporting units of the Corporation contain goodwill: one reporting unit in the Business Bank, the Retail Bank (a single reporting unit), and two reporting units in Wealth and Institutional Management. At the conclusion of the first step of the goodwill impairment test performed in the third quarter 2009, the estimated fair values of all reporting units substantially exceeded their carrying amounts, including goodwill, with the exception of the Retail Bank, which had a fair value that exceeded carrying value by five percent.

As of June 30, 2010, approximately $47 million of the Corporation’s consolidated goodwill of $150 million was associated with the Retail Bank. Given the result of the goodwill impairment test performed as of the third quarter 2009, the goodwill of the Retail Bank may be particularly sensitive to further deterioration in economic conditions, such as unemployment rates and home prices, which could impact assumptions associated with credit losses, loan growth and deposit gathering. In addition, potential legislative and regulatory changes could affect fee-based revenue. Economic conditions impact our assumptions related to imputed cost of equity capital, loss rates, interest and growth rates. Therefore, deterioration in economic conditions may cause the fair value of the Retail Bank to fall below the carrying value, resulting in a goodwill impairment charge. Any such charge would not affect the Corporation’s regulatory capital ratios, tangible common equity ratio or liquidity position.

(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.

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.

Table of Contents

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.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk

Quantitative and qualitative disclosures for the current period can be found in the “Market Risk” section of “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

ITEM 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. The Corporation maintains a set of disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to ensure that information required to be disclosed by the Corporation in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to the Corporation’s management, including the Corporation’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management has evaluated, with the participation of the Corporation’s Chief Executive Officer and Chief Financial Officer, the effectiveness of the Corporation’s disclosure controls and procedures as of the end of the period covered by this quarterly report (the “Evaluation Date”). Based on the evaluation, the Corporation’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the Evaluation Date, the Corporation’s disclosure controls and procedures are effective.

(b) Changes in Internal Control Over Financial Reporting. During the period to which this report relates, there have not been any changes in the Corporation’s internal controls over financial reporting procedures (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or that are reasonably likely to materially affect, such controls.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

For information regarding the Corporation’s legal proceedings, see “Part I. Item 1. Note 12 — 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, 2009 in response to Part I, Item 1A. of such Form 10-K, other than as amended in our Form 10-Q for the quarterly period ended March 31, 2010 in response to Part II, Item 1A. of such Form 10-Q. 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, 2009, as updated by Part II, “Item 1A. Risk Factors” in our Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2010:

Recently enacted legislation, actions recently taken by or proposed by the United States Department of Treasury, the Federal Deposit Insurance Corporation, the Federal Reserve Bank or other governmental entities, and legislation enacted in the future subject or may subject the Corporation to increased regulation, and the impact and expiration of such legislation and regulatory actions may adversely affect the Corporation.

On October 3, 2008, the Emergency Economic Stabilization Act of 2008 (the “EESA”) was signed into law. Pursuant to the EESA, the U.S. Treasury was granted the authority to take a range of actions for the purpose of stabilizing and providing liquidity to the U.S. financial markets and has proposed several programs, including the purchase by the U.S. Treasury of certain troubled assets from financial institutions and the direct purchase by the

Table of Contents

U.S. Treasury of equity of financial institutions. Pursuant to the EESA, the U.S. Treasury has the authority to, among other things, purchase up to $700 billion of mortgages, mortgage-backed securities and certain other financial instruments from financial institutions for the purpose of stabilizing and providing liquidity to the U.S. financial markets. In connection therewith, the U.S. Treasury introduced the Capital Purchase Program, under which it has purchased approximately $196 billion of preferred stock in eligible institutions, including the Corporation, to increase the flow of financing to U.S. businesses and consumers and to support the U.S. economy. On March 17, 2010, the Corporation fully redeemed the preferred stock previously issued to the U.S. Treasury under the Capital Purchase Program. The EESA also temporarily raised the limit on federal deposit insurance coverage provided by the FDIC from $100,000 to $250,000 per depositor.

On May 20, 2009, the Helping Families Save Their Homes Act of 2009, which extended the temporary increase in the standard maximum deposit insurance amount provided by the FDIC to $250,000 per depositor through December 31, 2013, was signed into law. This extension of the temporary $250,000 coverage limit (pursuant to the EESA) became effective immediately upon the President’s signature.

On October 14, 2008, the FDIC announced the development of a guarantee program under the systemic risk exception to the Federal Deposit Act. As a result of this regulatory initiative, the FDIC implemented the Temporary Liquidity Guarantee Program (“TLGP”) to strengthen confidence and encourage liquidity in the banking system. The TLGP is comprised of the Debt Guarantee Program (“DGP”) and the Transaction Account Guarantee Program (“TAGP”). The DGP guaranteed all newly issued senior unsecured debt (e.g., promissory notes, unsubordinated unsecured notes and commercial paper) up to prescribed limits issued by participating entities beginning on October 14, 2008 and continued through October 31, 2009. For eligible debt issued by that date, the FDIC will provide the guarantee coverage until the earlier of the maturity date of the debt or December 31, 2012 (or June 30, 2012 for debt issued prior to April 1, 2009). As of June 30, 2010, the Corporation had no senior unsecured debt outstanding under the DGP. The TAGP offers full guarantee for noninterest-bearing transaction accounts held at FDIC-insured depository institutions. The unlimited deposit coverage was voluntary for eligible institutions and was in addition to the $250,000 FDIC deposit insurance per account that was included as part of the EESA and the Helping Families Save Their Homes Act, respectively. The limits are presently scheduled to return to $100,000 on January 1, 2014. The TAGP coverage became effective on October 14, 2008 and continued for the Corporation until June 30, 2010. In April 2010, the FDIC adopted an interim rule extending the TAGP through December 31, 2010 for financial institutions that desire to continue TAGP participation. The Corporation notified the FDIC of its decision to opt-out of the FDIC’s TAGP extension, effective July 1, 2010. The impact of such decision on the Corporation’s deposit levels cannot be reliably determined at this time.

During the second quarter of 2009, the FDIC levied an industry-wide special assessment charge on insured financial institutions as part of the agency’s efforts to rebuild DIF. In November 2009, the FDIC amended regulations that required insured institutions to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009 and for all of 2010-2012. The prepaid assessments will be applied against future quarterly assessments (as they may be so revised) until the prepaid assessment is exhausted or the balance of the prepayment is returned, whichever occurs first. The FDIC is not precluded from changing assessment rates or from further revising the risk-based assessment system during the prepayment period or thereafter. Thus, we may also be required to pay significantly higher FDIC insurance assessments premiums in the future because market developments significantly depleted DIF and reduced the ratio of reserves to insured deposits.

The programs and regulations established or to be established under the EESA and Capital Purchase Program may have adverse effects upon the Corporation. It may face increased regulation of the financial services industry. Compliance with such regulation may increase the Corporation’s costs and limit its ability to pursue business opportunities. Also, participation in specific programs may subject the Corporation to additional restrictions. For example, due to the Corporation’s participation in the Capital Purchase Program, the Corporation issued a warrant to purchase 11,479,592 million of its common shares at an exercise price of $29.40 per share. The potential dilutive impact of the warrant may have an adverse effect on the market price of its common stock. On March 17, 2010, the Corporation fully redeemed the preferred stock previously issued to the U.S. Treasury under the Capital Purchase Program; however, the Corporation elected to not repurchase the warrant. On May 12, 2010, the U.S. Treasury sold the warrants for $16.00 per warrant. The sale by the U.S. Treasury had no impact on the Corporation’s equity and the warrants remain outstanding and are included in paid in capital. The Corporation’s participation in the TAGP required the payment of additional insurance premiums to the FDIC through June 30, 2010, in addition to the FDIC’s regular and special assessments. The effects of such recently enacted legislation and regulatory actions on the Corporation cannot reliably be determined at this time. Moreover, as some of the legislation and regulatory actions previously implemented in response to the recent financial crisis expire, the impact of the conclusion of these programs on the financial sector and on the economic recovery is unknown. Any delay in

Table of Contents

the economic recovery or a continuation or worsening of current financial market conditions could adversely affect the Corporation.

Recently, the Federal Reserve adopted amendments to its Regulation E that were effective on July 1, 2010. The changes affect the circumstances when the Corporation will be able to charge its clients overdraft fees.

On January 14, 2010, the current administration announced a proposal to impose a fee (the “Financial Crisis Responsibility Fee”) on those financial institutions that benefited from recent actions taken by the U.S. government to stabilize the financial system. If implemented as initially proposed, the Financial Crisis Responsibility Fee will be applied to firms with over $50 billion in consolidated assets, and, therefore, by its terms would apply to the Corporation.

On July 21, 2010, 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. As portions of the Financial Reform Act are implemented, the Corporation will continue to monitor and evaluate its impact on the operations of the Corporation and its subsidiaries.

We can neither predict when or whether future regulatory or legislative reforms will be enacted nor what their contents will be. The impact of any future legislation or regulatory actions on the Corporation’s businesses or operations cannot be reliably determined at this time, and such impact may adversely affect the Corporation.
