Notes to Consolidated Financial Statements (unaudited)
Comerica Incorporated and Subsidiaries
Note 1 — Basis of Presentation and Accounting Policies
     The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles 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 U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The results of operations for the three months ended March 31, 2007, are not necessarily indicative of the results that may be expected for the year ending December 31, 2007. Certain items in prior periods have been 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, 2006.
Income Taxes
     On January 1, 2007, the Corporation adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes- an interpretation of FASB Statement No. 109,” (FIN 48). FIN 48 permits the Corporation to elect to change its accounting policy as to where interest and penalties on tax liabilities is classified in the consolidated statements of income. Effective January 1, 2007, the Corporation prospectively changed its accounting policy to classify interest and penalties on tax liabilities in the “provision for income taxes” on the consolidated statements of income. The provision for income taxes included interest on tax liabilities of $1 million for the three months ended March 31, 2007. In the first quarter 2007, the Securities and Exchange Commission requested that the American Institute of Certified Public Accountants clarify that an election to change classification of interest and penalties on tax liabilities under the Interpretation could only be prospective. Therefore, for all prior periods presented, interest and penalties on tax liabilities remained classified in “other noninterest expenses” on the consolidated statements of income. Additional information regarding FIN 48 can be found in Note 6.
Note 2 – Pending Accounting Pronouncements
     In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” (SFAS 157), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 applies whenever other standards require (or permit) assets or liabilities to be measured at fair value, and therefore, does not expand the use of fair value in any new circumstances. Fair value refers to the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the Corporation transacts. SFAS 157 clarifies that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, for example, the Corporation’s own data. SFAS 157 requires fair value measurements to be separately disclosed by level within the fair value hierarchy. SFAS 157 is effective for fiscal years beginning after November 15, 2007. Accordingly, the Corporation will adopt the provisions of SFAS 157 in the first quarter of 2008. The Corporation is currently evaluating the guidance contained in SFAS 157 to determine the effect adoption of the guidance will have on the Corporation’s financial condition and results of operations.
     In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities – Including an amendment of FASB Statement No. 115,” (SFAS 159). SFAS 159 provides entities with the irrevocable option to account for selected financial assets and liabilities at fair value on a contract-by-contract basis. Under the option, any changes in fair value would be included in earnings. The Corporation can elect to apply the standard prospectively and measure certain financial instruments at fair value beginning January 1, 2008. The Corporation is currently evaluating the guidance contained in SFAS 159, and has yet to determine which assets or liabilities (if any) will be selected. At adoption, the difference between the carrying amount and the fair value of existing eligible assets and liabilities selected (if any) would be recognized via a cumulative adjustment to beginning retained earnings on January 1, 2008.

     At March 31, 2007, the Corporation had 126 securities in an unrealized loss position, including 122 Government-sponsored enterprise securities (i.e., FMNA, FHLMC). The unrealized losses resulted from changes in market interest rates, not credit quality. The Corporation has the ability and intent to hold these available-for-sale investment securities until maturity or market price recovery, and full collection of the amounts due according to the contractual terms of the debt is expected; therefore, the Corporation does not consider these investments to be other-than-temporarily impaired at March 31, 2007.
     At March 31, 2007, investment securities having a carrying value of $1.8 billion were pledged where permitted or required by law to secure $758 million of liabilities, including public and other deposits, and derivative instruments. This included securities of $946 million pledged with the Federal Reserve Bank to secure actual treasury tax and loan borrowings of $2 million at March 31, 2007, and potential borrowings of up to an additional $848 million. The remaining pledged securities of $867 million are primarily with state and local government agencies to secure $756 million of deposits and other liabilities, including deposits of the State of Michigan of $229 million at March 31, 2007.

     A loan is impaired when it is probable that interest and principal payments will not be made in accordance with the contractual terms of the loan agreement. Consistent with this definition, all nonaccrual and reduced-rate loans (with the exception of residential mortgage and consumer loans) are impaired. Impaired loans that are restructured and meet the requirements to be on accrual status are included with total impaired loans for the remainder of the calendar year of the restructuring. There were no loans included in the $213 million of impaired loans at March 31, 2007 that were restructured and met the requirements to be on accrual status. Impaired loans averaged $214 million and $130 million for the three month periods ended March 31, 2007 and 2006, respectively. The following presents information regarding the period-end balances of impaired loans:
                 
    Three Months Ended   Year Ended
(in millions)   March 31, 2007   December 31, 2006
 
Total period-end nonaccrual business loans

     In February 2007, the Corporation issued $515 million of 6.576% subordinated notes that relate to trust preferred securities issued by an unconsolidated subsidiary. The notes pay interest on February 20 and August 20 of each year, beginning August 20, 2007 through February 20, 2032. Beginning February 20, 2032, the notes will bear interest at an annual rate based on LIBOR, payable monthly on the 20th day of each calendar month until the scheduled maturity date of February 20, 2037. The subordinated notes qualify as Tier 1 capital. The Corporation used the proceeds for the March 2007 redemption of a $350 million, 7.60% subordinated note due 2050 and to repurchase additional shares.
     In March 2007, Comerica Bank (the Bank), a subsidiary of the Corporation, issued an additional $250 million of 5.75% subordinated notes under a series initiated in November 2006. The notes pay interest on May 21 and November 21 of each year, beginning with May 21, 2007, and mature November 21, 2016. The Bank used the net proceeds for general corporate purposes.
     The Bank issued $900 million of floating rate notes during the first quarter of 2007 under an existing $15 billion medium-term senior note program. The Bank used the proceeds for general corporate purposes.

Note 6 — Income Taxes and Tax-Related Items
     The provision for income taxes is computed by applying statutory federal income tax rates to income before income taxes as reported in the consolidated financial statements after deducting non-taxable items, principally income on bank-owned life insurance and interest income on state and municipal securities. State and foreign taxes are then added to the federal tax provision. In addition, beginning January 1, 2007, interest on tax liabilities is classified in the provision for income taxes.
     The Corporation adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes- an interpretation of FASB Statement No. 109,” (FIN 48) on January 1, 2007. As a result, the Corporation recognized an increase in the liability for unrecognized tax benefits of approximately $5 million at January 1, 2007, accounted for as a change in accounting principle via a decrease to the opening balance of retained earnings. At January 1, 2007, the Corporation had unrecognized tax benefits of approximately $72 million. After consideration of the effect of the federal tax benefit available on unrecognized state tax benefits, the total amount of unrecognized tax benefits that, if recognized, would affect the Corporation’s effective tax rate was approximately $66 million at January 1, 2007.
     The Corporation recognized approximately $1 million in interest on tax liabilities for the three months ended March 31, 2007 included in the “provision for income taxes” on the consolidated statements of income, compared to approximately $26 million, included in “other noninterest expenses” on the consolidated statements of income, for the same period in 2006. For further information regarding the change in classification of interest and penalties on tax liabilities as a result of applying the provisions of FIN 48, refer to footnote 1 to these consolidated financial statements. The Corporation had approximately $71 million and $70 million accrued for the payment of interest at March 31, 2007 and January 1, 2007, respectively. Upon adoption of FIN 48, the Corporation recorded an $8 million decrease to interest on tax liabilities as an increase to the opening balance of retained earnings.
     In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the Internal Revenue Service (IRS) questions and/or challenges the tax position taken by the Corporation with respect to those transactions. The Corporation engaged in certain types of structured leasing transactions that the IRS disallowed in its examination of the Corporation’s federal tax returns for the years 1996 through 2000. The IRS also disallowed foreign tax credits associated with the interest on a series of loans to foreign borrowers. The Corporation has had ongoing discussions with the IRS Appeals Office related to the disallowance of the foreign tax credits associated with the loans and adjusted tax and related interest reserves based on settlements discussed. The Corporation believes it is reasonably possible that a final settlement amount with the IRS will be agreed upon within the next twelve months. The FIN 48 unrecognized tax benefit related to the foreign tax credits was approximately $38 million at March 31, 2007, and reflects the Corporation’s current settlement expectations.
     Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that current tax reserves, determined in accordance with FIN 48, 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.
     The Corporation believes that its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The Corporation intends to vigorously defend its positions taken in those returns in accordance with its view of the law controlling these activities. However, as noted above, the IRS examination team, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law. After evaluating the risks and opportunities, the best outcome may result in a settlement. The ultimate outcome for each position is not known.
     The following tax years remain subject to examination as of March 31, 2007:
         
Jurisdiction   Tax Years
Federal
    2001-2006  
California
    1998-2006

Note 6 — Income Taxes and Tax-Related Items (continued)
     On January 1, 2007, the Corporation adopted the provisions of FASB Staff Position No. FAS 13-2, “Accounting for a Change or Projected Change in the Timing of Cash Flows Relating to Income Taxes Generated by a Leveraged Lease Transaction,” (FSP 13-2). FSP 13-2 requires a recalculation of the lease income from the inception of a leveraged lease if, during the lease term, the expected timing of the income tax cash flows generated from a leveraged lease is revised. The Corporation recorded a one-time non-cash after-tax charge to beginning retained earnings of $46 million to reflect changes in expected timing of the income tax cash flows generated from affected leveraged leases, which is expected to be recognized as income over periods ranging from 4 years to 20 years.
Note 7 — 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, the change in the accumulated foreign currency translation adjustment and the change in the accumulated defined benefit and other postretirement plans adjustment. The Consolidated Statements of Changes in Shareholders’ Equity on page 5 include only combined other comprehensive income (loss), net of tax. The following table presents reconciliations of the components of the accumulated other comprehensive income (loss) for the three months ended March 31, 2007 and 2006. Total comprehensive income totaled $230 million and $166 million for the three months ended March 31, 2007 and 2006, respectively. The $64 million increase in total comprehensive income in the three months ended March 31, 2007, when compared to the same period in the prior year, resulted principally from increases in net unrealized gains on investment securities available-for-sale ($37 million) due to changes in the interest rate environment, and net gains on cash flow hedges ($29 million).

(1)   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.
 
(2)   Unrealized gains represent receivables from derivative counterparties, and therefore expose the Corporation to credit risk. Credit risk, which excludes the effects of any collateral or netting arrangements, is measured as the cost to replace, at current market rates, contracts in a profitable position.
 
(3)   The fair values of derivative instruments represent the estimated amounts the Corporation would receive or pay to terminate or otherwise settle the contracts at the balance sheet date. The fair values of all derivative instruments are reflected in the consolidated balance sheets.

Note 10 - Derivative Instruments (continued)
Risk Management
     Fluctuations in net interest income due to interest rate risk result from the composition of assets and liabilities and the mismatches in the timing of the repricing of these assets and liabilities. In addition, external factors such as interest rates, and the dynamics of yield curve and spread relationships can affect net interest income. The Corporation utilizes simulation analyses to project the sensitivity of net interest income to changes in interest rates. Cash instruments, such as investment securities, as well as derivative instruments, are employed to manage exposure to these and other risks, including liquidity risk.
     For hedge relationships accounted for under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” at inception of the hedge the Corporation uses either the short-cut method if it qualifies, or applies dollar offset or statistical regression analysis to assess effectiveness. The short-cut method is used for fair value hedges of medium and long-term debt. This method allows for the assumption of zero hedge ineffectiveness and eliminates the requirement to further assess hedge effectiveness on these transactions. For SFAS No. 133 hedge relationships to which the Corporation does not apply the short-cut method, dollar offset or statistical regression analysis is used at inception and consistently applied for each reporting period thereafter to assess whether the derivative used has been and is expected to be highly effective in offsetting changes in the fair value or cash flows of the hedged item. All components of each derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. Net hedge ineffectiveness is recorded in “other noninterest income” on the consolidated statements of income.
     The following table presents net hedge ineffectiveness gains (losses) by risk management hedge type:

     As an end-user, the Corporation employs a variety of financial instruments for risk management purposes. As part of a fair value hedging strategy, the Corporation has entered into interest rate swap agreements for interest rate risk management purposes. These interest rate swap agreements effectively modify exposure to interest rate risk by converting fixed-rate deposits and 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.
     As part of a cash flow hedging strategy, the Corporation entered into predominantly 3 year interest rate swap agreements (weighted-average original maturity of 3.0 years) that effectively convert a portion of its existing and forecasted floating-rate loans to a fixed-rate basis, which will reduce the impact of interest rate changes on future interest income over the next 1 to 2 years. Approximately 11 percent ($5.5 billion) of outstanding loans were designated as hedged items to interest rate swap agreements at March 31, 2007. Interest rate swap agreements designated as cash flow hedges decreased interest and fees on loans by $24 million and $25 million, during the three month periods ended March 31, 2007 and 2006, respectively. If interest rates, interest yield curves and notional amounts remain at current levels, the Corporation expects to reclassify $30 million of net losses on derivative instruments from accumulated other comprehensive income to earnings during the next twelve months due to receipt of variable interest associated with existing and forecasted floating-rate loans.
     Foreign exchange rate risk arises from changes in the value of certain assets and liabilities denominated in foreign currencies. The Corporation employs cash instruments, such as investment securities, as well as derivative instruments, to manage exposure to these and other risks. In addition, the Corporation uses foreign exchange forward and option contracts to protect the value of its foreign currency investment in foreign subsidiaries. Realized and unrealized gains and losses from foreign exchange forward and option contracts used to protect the value of investments in foreign

Note 10 — Derivative Instruments (continued)
subsidiaries are not included in the statement of income, but are shown in the accumulated foreign currency translation adjustment account included in other comprehensive income, with the related amounts due to or from counterparties included in other liabilities or other assets. During the three month period ended March 31, 2006, in accordance with SFAS No. 52, “Foreign Currency Translation,” the Corporation recognized a net gain of less than $0.5 million in accumulated foreign currency translation adjustment, related to the forward foreign exchange contracts. The Corporation did not hold any forward foreign exchange contracts recognized in accumulated foreign currency translation adjustment during the three months ended March 31, 2007.
     Management believes these strategies achieve the desired relationship between the rate maturities of assets and funding sources which, in turn, reduces the overall exposure of net interest income to interest rate risk, although there can be no assurance that such strategies will be successful. The Corporation also uses various other types of derivative instruments to mitigate interest rate and foreign currency risks associated with specific assets or liabilities, which are reflected in the table on page 17. Such instruments may include interest rate caps and floors, foreign exchange forward contracts, foreign exchange option contracts and foreign exchange cross-currency swaps.
     The following table summarizes the expected maturity distribution of the notional amount of risk management interest rate swaps and provides the weighted-average interest rates associated with amounts to be received or paid on interest rate swap agreements as of March 31, 2007. Swaps have been grouped by asset and liability designation.

     The Corporation had commitments to purchase investment securities for its trading account and available-for-sale portfolios totaling $111 million at March 31, 2007 and $20 million at December 31, 2006. Commitments to sell investment securities related to the trading account portfolio totaled $8 million at March 31, 2007 and $16 million at December 31, 2006. Outstanding commitments expose the Corporation to both credit and market risk.
Customer-Initiated and Other
     Fee income is earned from entering into various transactions, principally foreign exchange contracts, interest rate contracts, and energy derivative contracts at the request of customers. The Corporation mitigates market risk inherent in customer-initiated interest rate and energy contracts by taking offsetting positions, except in those circumstances when the amount, tenor and/or contracted rate level results in negligible economic risk, whereby the cost of purchasing an offsetting contract is not economically justifiable. 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 less than $0.5 million of net gains in both the three month periods ended March 31, 2007 and 2006, which were included in “other noninterest income” in the consolidated statements of income. The fair value of derivative instruments held or issued in connection with customer-initiated activities, including those customer-initiated derivative contracts where the Corporation does not enter into an offsetting derivative contract position, is included in the table on page 17.
     Fair values for customer-initiated and other derivative instruments represent the net unrealized gains or losses on such contracts and are recorded in the consolidated balance sheets. Changes in fair value are recognized in the consolidated income statements. The following table provides the average unrealized gains and losses, and noninterest income generated on customer-initiated and other interest rate contracts, energy derivative contracts and foreign exchange contracts.

Note 11 — Standby and Commercial Letters of Credit and Financial Guarantees
     The total contractual amounts of standby letters of credit and financial guarantees and commercial letters of credit at March 31, 2007 and December 31, 2006, which represents the Corporation’s credit risk associated with these instruments, are shown in the table below.

  $ 6,462     $ 6,584  
Commercial letters of credit
    215       249  
 
     Standby and commercial letters of credit and financial guarantees represent conditional obligations of the Corporation, which guarantee the performance of a customer to a third party. Standby letters of credit and financial guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. These contracts expire in decreasing amounts through the year 2016. Commercial letters of credit are issued to finance foreign or domestic trade transactions and are short-term in nature. The Corporation may enter into participation arrangements with third parties, which effectively reduce the maximum amount of future payments which may be required under standby letters of credit. These risk participations covered $607 million of the $6,462 million of standby letters of credit and financial guarantees outstanding at March 31, 2007. The carrying value of the Corporation’s standby and commercial letters of credit and financial guarantees, which is included in “accrued expenses and other liabilities” on the consolidated balance sheet, totaled $75 million and $78 million at March 31, 2007 and December 31, 2006, respectively.
Note 12 – Contingent Liabilities
Legal Proceedings
     The Corporation and certain of its subsidiaries are subject to various pending or threatened legal proceedings arising out of the normal course of business or operations. 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, determined in accordance with SFAS No. 5, “Accounting for Contingencies” (SFAS 5), 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 or results of operations.

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 March 31, 2007. 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 2006 Annual Report.
     Beginning in the first quarter 2007, the Corporation assigned to the business segments the portion of the allowance for loan losses maintained to capture probable losses due to the inherent imprecision in the risk rating system and new business migration risk. This portion of the allowance was previously included in the Other category. In addition, the Corporation changed its method of allocating corporate overhead. Corporate overhead is assigned 50 percent based on the ratio of the business segment’s noninterest expenses to total noninterest expenses incurred by all business segments and 50 percent based on the ratio of the business segment’s attributed equity to total attributed equity of all business segments. Formerly, corporate overhead was allocated based entirely on noninterest expenses. Prior periods have been restated to reflect these changes. For informational purposes, business segment results for the years ended December 31, 2006 and 2005 have been updated to reflect these changes and are presented in the section entitled “Supplemental Information” in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Note 13 — Business Segment Information (continued)
     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. Market segment results are provided as supplemental information to the business segment results and may not meet all operating segment criteria as set forth in Statement of Financial Accounting Standards No. 131, “Disclosures about Segments of an Enterprise and Related Information,” (SFAS 131).
     The Midwest market consists of operations located in the states of Michigan, Ohio and Illinois. Currently, Michigan operations represent the significant majority of the Midwest market.
     The Western market consists of operations located in the states of California, Arizona, Nevada, Colorado and Washington. Currently, California operations represent the significant majority of the Western market.
     The Texas and Florida markets consist of operations located in the states of Texas and Florida, respectively.
     Other Markets includes the Corporation’s investment management and trust alliance businesses, as well as all other markets in which the Corporation has operations, except for the International market, as described below.
     The International market represents the activity of the Corporation’s International Finance division, which provides banking services primarily to foreign-owned, North American-based companies.
     The Finance & Other Businesses segment includes the Corporation’s securities portfolio, asset and liability management activities, discontinued operations, the income and expense impact of equity and cash not assigned to specific business/market segments, tax benefits not assigned to specific business/market segments and miscellaneous other expenses of a corporate nature. This segment includes responsibility 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.
     Beginning in the first quarter 2007, the Corporation assigned to the market segments the portion of the allowance for loan losses maintained to capture probable losses due to the inherent imprecision in the risk rating system and new business migration risk. This portion of the allowance was previously included in the Other category. In addition, the Corporation changed its method of allocating corporate overhead. Corporate overhead is assigned 50 percent based on the ratio of the market segment’s noninterest expenses to total noninterest expenses incurred by all market segments and 50 percent based on the ratio of the market segment’s attributed equity to total attributed equity of all market segments. Prior periods have been restated to reflect these changes. For informational purposes, business segment results for the years ended December 31, 2006 and 2005 have been updated to reflect these changes and are presented in the section entitled “Supplemental Information” in “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

NOTE 14 –Discontinued Operations
     In December 2006, the Corporation sold its ownership interest in Munder Capital Management (Munder) to an investor group. As a result of the sale transaction, the Corporation accounted for Munder as a discontinued operation and all prior periods presented have been restated. As such, Munder was reported in “Other” and “Finance & Other” for business and market segment reporting purposes, respectively. Munder was previously reported in “Wealth & Institutional Management” and “Other Markets” for business and market segment reporting purposes, respectively. The assets and liabilities related to the discontinued operations of Munder are not material and have not been reclassified on the consolidated balance sheets.
     The components of net income from discontinued operations for the three months ended March 31, 2007 and 2006, respectively, were as follows:

     During the first quarter 2007, the Corporation completed the sale of a portfolio of loans related to manufactured housing for about the fair value recorded at December 31, 2006. As a result of the sale transaction, the Corporation transferred $74 million of loans, which were classified in “other short-term investments” on the consolidated balance sheet at December 31, 2006, to the buyer.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Results of Operations
     Net income for the three months ended March 31, 2007 was $190 million, a decrease of $4 million, or three percent, from $194 million reported for the three months ended March 31, 2006. Quarterly diluted net income per share increased less than one percent to $1.19 in the first quarter 2007, compared to $1.18 in the same period a year ago. Income from continuing operations for the three months ended March 31, 2007 was $189 million, a decrease of $18 million, or nine percent, from $207 million reported for the three months ended March 31, 2006. Quarterly diluted income from continuing operations per share decreased six percent to $1.19 in the first quarter 2007, compared to $1.26 in the same period a year ago. The decrease in income from continuing operations in the first quarter 2007 from the comparable quarter last year resulted primarily from a $35 million increase in the provision for credit losses (the net result of a $50 million increase in the provision for loan losses and a $15 million decrease in the provision for credit losses on lending-related commitments), partially offset by a $23 million increase in net interest income. Return on average common shareholders’ equity was 14.86 percent and return on average assets was 1.33 percent for the first quarter 2007, compared to 15.33 percent and 1.41 percent, respectively, for the comparable quarter last year. Return on average common shareholders’ equity from continuing operations was 14.83 percent and return on average assets from continuing operations was 1.33 percent for the first quarter 2007, compared to 16.31 percent and 1.50 percent, respectively, for the same period in 2006.
Discontinued Operations
     In December 2006, the Corporation sold its ownership interest in Munder Capital Management (Munder) to an investor group. The Corporation accounted for Munder as a discontinued operation and all prior periods presented have been restated. The remaining discussion and analysis of the Corporation’s results of operations is based on results from continuing operations. For detailed information concerning the sale of Munder and the components of discontinued operations, refer to Note 14 to these consolidated financial statements.
Full-year 2007 Outlook.
     For full-year 2007, management expects the following compared to full-year 2006:
  Mid to high single-digit average loan growth, excluding Financial Services Division loans, with flat growth in the Midwest market, and low double-digit growth in the Western and Texas markets
 
  Average earning asset growth slightly less than average loan growth
 
  Average Financial Services Division noninterest-bearing deposits remaining at first quarter 2007 level of $3.5 billion. Financial Services Division loans will fluctuate in 2007 with the level of noninterest-bearing deposits
 
  Average full year net interest margin of about 3.75 percent to 3.80 percent
 
  Average net credit-related charge-offs (including both net loan charge-offs and charge-offs on lending-related commitments) of about 20 basis points of average loans, with a provision for credit losses modestly exceeding net charge-offs
 
  Low single-digit growth in noninterest income, from a 2006 adjusted base of $820 million which excludes the Financial Services Division-related lawsuit settlement and the loss on sale of the Mexican bank charter
 
  Flat noninterest expenses, excluding the provision for credit losses on lending-related commitments. Outlook reflects anticipated 2007 costs associated with the previously announced headquarters move to Dallas, Texas (expected to be about $10 million) and tax-related interest in 2006 (classified in the provision for income taxes in 2007)
 
  Effective tax rate of about 32 percent
 
  Active capital management within targeted capital ratios (Tier 1 common of 6.50 percent to 7.50 percent and Tier 1 of 7.25 percent to 8.25 percent)
Net Interest Income
     The rate-volume analysis in Table I details the components of the change in net interest income on a fully taxable equivalent (FTE) basis for the three months ended March 31, 2007. On a FTE basis, net interest income increased $23 million to $503 million for the three months ended March 31, 2007, from $480 million for the comparable period in 2006. The increase in net interest income in the first quarter 2007, compared to the same period in 2006, resulted primarily from loan growth, partially offset by a decline in noninterest-bearing deposits and changes in funding mix. Average earning assets increased $2.1 billion, or four percent, to $53.1 billion in the first quarter 2007, compared to $51.0 billion in the first quarter 2006, primarily due to a $2.4 billion, or five percent, increase in average loans to $48.9 billion in the first quarter 2007. The net interest margin (FTE) for the three months ended March 31, 2007 was 3.82 percent, compared to 3.80 percent for the comparable period in 2006. The

27


Table of Contents

increase in the net interest margin (FTE) resulted from the increased value of noninterest-bearing deposits in a higher interest rate environment and the results of the operations of the Corporation’s Financial Services Division as described below, partially offset by a change in the interest-bearing deposit mix toward higher-cost deposits and loan growth in excess of deposit growth.
     Financial Services Division customers deposit large balances (primarily noninterest-bearing) and the Corporation pays certain customer services expenses (included in “noninterest expenses” on the consolidated statements of income) and/or makes low-rate loans (included in “net interest income” on the consolidated statements of income) to such customers. Footnote (1) to Table I displays average Financial Services Division loans and deposits, with related interest income/expense and average rates. As shown in footnote (2) to Table I, the impact of Financial Services Division loans (primarily low-rate) on net interest margin (assuming the loans were funded by Financial Services Division noninterest-bearing deposits) was a decrease of 11 basis points and 22 basis points in the three month periods ended March 31, 2007 and 2006, respectively.
     For further discussion of the effects of market rates on net interest income, refer to “Item 3. Quantitative and Qualitative Disclosures about Market Risk.”
     Management currently expects average full-year 2007 net interest margin of about 3.75 to 3.80 percent.

Provision for Credit Losses
     The provision for loan losses was $23 million for the first quarter 2007, compared to a negative provision of $27 million for the same period in 2006. The Corporation establishes this provision to maintain an adequate allowance for loan losses, which is discussed under the “Credit Risk” subheading in the section entitled “Risk Management” of this financial review. The $50 million increase in the provision for loan losses in the three-month period ended March 31, 2007, when compared to the same period in 2006, resulted primarily from loan growth, challenges in the automotive industry and the Michigan commercial real estate industry and a leveling off of credit quality improvement trends. These credit trends reflect economic conditions in the Corporation’s three largest geographic markets. While the economic conditions in the Corporation’s Michigan market deteriorated over the last year, the economic conditions in the Texas market have continued to improve somewhat faster than growth in the national economy, while California appears to be improving, but at a rate equal to the nation as a whole. The average Michigan Business Activity index compiled by the Corporation for the first two months of 2007 declined approximately two percent when compared to the same two months in 2006, and to the average for full-year 2006. Intense restructuring efforts in the Michigan-based automotive sector are creating a significant drag on the state economy. Forward-looking indicators suggest that economic conditions in the Corporation’s primary markets are likely to resemble recent trends for the remainder of 2007.
     The provision for credit losses on lending-related commitments was a negative provision of $2 million, compared to a provision of $13 million for the comparable period in 2006. The Corporation establishes this provision to maintain an adequate allowance to cover probable credit losses inherent in lending-related commitments. The $15 million decrease in the three months ended March 31, 2007, when compared to the same period in 2006, was primarily the result of a decrease in specific reserves related to unused commitments to extend credit to customers in the automotive industry, due to sales of these unfunded commitments and improvements in the associated market values.
     Management currently expects full-year 2007 average net credit-related charge-offs (including both net loan and lending-related commitment charge-offs) of about 20 basis points of full-year average loans, with a provision for credit losses modestly exceeding net charge-offs.
Noninterest Income
     Noninterest income was $203 million for the three months ended March 31, 2007, an increase of $8 million, or four percent, compared to $195 million for the same period in 2006. The increase in noninterest income in the first quarter 2007 was primarily due to a $6 million increase in fiduciary income and a first quarter 2006 impairment charge of $5 million on the Mexican bank charter held-for-sale which was included in “net gain (loss) on sales of businesses” on the consolidated statements of income. In addition, “other noninterest income” for the three months ended March 31, 2007 included nominal risk management hedge gains from interest rate and foreign exchange contracts, compared to $2 million of net losses for the same period in 2006. Offsetting these increases was a $7 million decline in net income (loss) from principal investing and warrants in the first quarter 2007, when compared to the same period in the prior year.
     Management currently expects low single-digit growth in noninterest income in full-year 2007, from a 2006 base of $820 million which excludes the Financial Services Division-related lawsuit settlement and the loss on sale of the Mexican bank charter in 2006.
Noninterest Expenses
     Noninterest expenses were $407 million for the three months ended March 31, 2007, a decrease of $22 million, or five percent, from $429 million for the comparable period in 2006. Total salaries and benefits expense increased $9 million, or four percent, in the three months ended March 31, 2007, compared to the same period in 2006, the components of which are shown in the table below. The $4 million increase in regular salaries was primarily the result of annual merit increases. Share-based compensation expense reflected $11 million and $9 million in the first quarter 2007 and 2006, respectively, from the annual award of restricted stock to retirement-eligible employees, granted in the first quarter each year, which must be expensed in the period granted. Net occupancy and equipment expense, on a combined basis, increased $7 million, or 14 percent, to $50 million in the three months ended March 31, 2007, compared to the same period in 2006. Net occupancy and equipment expense increased primarily due to the addition of nine new banking centers in the first quarter 2007, along with 25 new banking centers in full-year 2006. The provision for credit losses on lending-related commitments decreased $15 million in the first quarter 2007 from the comparable period in 2006, due to the reasons cited in the “Provision for Credit Losses” section above. Customer services expense, which represents compensation provided to customers

and is one method to attract and retain title and escrow deposits in the Corporation’s Financial Services Division, was $14 million in the first quarter 2007, an increase of $1 million, compared to $13 million in the first quarter 2006. The amount of customer services expense varies from period to period as a result of changes in the level of noninterest-bearing deposits in the Corporation’s Financial Services Division, the level of the low-rate loans, and the earnings credit allowances provided on these deposits, as well as a competitive environment.

     Beginning January 1, 2007, the Corporation prospectively classified interest expense on tax liabilities in the “provision for income taxes” on the consolidated statements of income. For further discussion of interest on tax liabilities, refer to Note 1 to the consolidated financial statements, and to the following section, entitled “Provision for Income Taxes and Tax-Related Interest.” In the first quarter 2006, $26 million of interest expense on tax liabilities was included in “other noninterest expenses” on the consolidated statements of income.
     Management currently expects flat noninterest expenses for the full-year 2007, compared to 2006 levels, with 2007 including costs associated with the previously announced headquarters move to Dallas, Texas (about $10 million in 2007, of the $15 to $20 million three-year total), with 2006 including tax-related interest of $38 million, and excluding the provision for credit losses on lending-related commitments from both years.
Provision for Income Taxes and Tax-related Interest
     The provision for income taxes for the first quarter 2007 was $86 million, compared to $65 million for the same period a year ago. The effective tax rate was 31 percent and 24 percent for the first quarter 2007 and 2006, respectively. In the first quarter 2006, the IRS completed the examination of the Corporation’s federal tax returns for the years 1996 through 2000. Tax reserves, which include the provision for income taxes and interest expense on tax liabilities (included in “other noninterest expenses” in 2006) were adjusted to reflect the resolution of those tax years, and to reflect an updated assessment of reserves on certain types of structured lease transactions and a series of loans to foreign borrowers. The effect of these adjustments decreased federal taxes ($16 million) and increased interest expense on tax liabilities ($23 million, $15 million after-tax) in the first quarter 2006.
     Management currently expects an effective tax rate for the full-year 2007 of about 32 percent.
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 the consolidated financial statements presents financial results of these business segments for the three months ended March 31, 2007 and 2006. 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 consolidated financial statements and Note 24 to the consolidated financial statements in the Corporation’s 2006 Annual Report.

     The Business Bank’s net income of $141 million decreased $10 million, or seven percent, for the three months ended March 31, 2007, compared to the three months ended March 31, 2006. Net interest income (FTE) was $329 million, an increase of $14 million from the comparable prior year period. The increase in net interest income (FTE) was primarily due to a $3.4 billion increase in average loan balances (excluding Financial Services Division) and the results of the operations of the Corporation’s Financial Services Division, partially offset by a decline in loan spreads. Average low-rate Financial Services Division loan balances declined $1.3 billion in the first quarter 2007 and average Financial Services Division noninterest-bearing deposits declined $1.2 billion. The provision for loan losses increased $43 million, from the comparable period in the prior year, primarily due to an increase in specific reserves and implementation of a retail trade (gasoline delivery) industry reserve, loan growth in the first quarter 2007, and credit improvements recognized in the first quarter 2006. Noninterest income of $61 million decreased $2 million from the comparable prior year period, primarily due to a negative $4 million warrant fair value adjustment in the first quarter 2007 and a $2 million decrease in investment banking fees, partially offset by a $5 million impairment charge on Mexican bank charter assets held-for-sale that was recognized in the first quarter 2006. Noninterest expenses of $170 million for the three months ended March 31, 2007 decreased $23 million from the same period in the prior year, primarily due to a $17 million decline in the provision of loan losses on lending-related commitments.
     The Retail Bank’s net income decreased $5 million, or 13 percent, to $33 million for the three months ended March 31, 2007, compared to the three months ended March 31, 2006. Net interest income (FTE) of $157 million increased $2 million from the comparable period in the prior year as the benefit of a $297 million increase in average deposit balances was partially offset by a decline in loan spreads. The provision for loan losses decreased $1 million. The Retail Bank included $2.2 billion of the Corporation’s average consumer loan portfolio of $4.1 billion of residential mortgage, home equity and other consumer loans in the first quarter 2007. These loans were originated as part of a full-service customer relationship. The Corporation does not have any sub-prime mortgage programs. Noninterest income of $52 million increased $2 million from the comparable prior year period. Noninterest expenses of $153 million for the three months ended March 31, 2007, increased $10 million from the same period in the prior year, primarily due to a $4 million increase in salaries and employee benefits expense and a $2 million increase in occupancy expenses related to the addition of new banking centers. The Corporation opened nine banking centers in the first quarter 2007 and is on target to open 30 total banking centers in 2007.
     Wealth & Institutional Management’s net income increased $4 million, or 25 percent, to $21 million for the three months ended March 31, 2007, compared to the three months ended March 31, 2006. Net interest income (FTE) of $36 million decreased $1 million from the comparable period in the prior year as decreases in loan spreads and average deposit balances were partially offset by an increase in average loan balances. The provision for loan losses decreased $1 million due to improved credit risk. Noninterest income of $71 million increased $7 million from the comparable period in the prior year, primarily due to a $4 million increase in fiduciary income and a $1 million gain from the sale of an insurance subsidiary in the first quarter 2007. Noninterest expenses of $76 million increased $1 million from the same period in the prior year.
     Net income for the Finance Division was $1 million for the three months ended March 31, 2007, compared to a net loss of $2 million for the three months ended March 31, 2006. Contributing to the increase in net income was a $7 million increase in net interest income (FTE), primarily due to rising rate environment in which income received from the lending-related business increased faster than the longer-term value attributed to deposits generated by the business units. Partially offsetting the increase in net interest income was a $1 million decrease in noninterest income.

     The net loss in the Other category was $6 million for the three months ended March 31, 2007, compared to a net loss of $10 million for the three months ended March 31, 2006. Discontinued operations, net of related taxes, had a net loss of $13 million for the three months ended March 31, 2006, primarily due to an $8 million, net of taxes, transition adjustment expense related to SFAS No. 123 (R) recorded in the first quarter 2006. Noninterest expenses decreased $10 million due to timing differences between when corporate overhead expenses are reflected as a consolidated expense and when the expenses are allocated to the business segments. Offsetting the decrease in noninterest expenses was a $9 million increase in the provision for loan losses due to the methodology used to assign reserves to business units.
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 the consolidated financial statements contains a description and presents financial results of these market segments for the three months ended March 31, 2007 and 2006.

Net interest income (FTE) of $244 million increased $1 million from the comparable period in the prior year as increases in average loan balances and deposit spreads were offset by decreases in loan spreads and average deposit balances. The provision for loan losses increased $30 million, primarily due to an increase in specific reserves and implementation of a retail trade (gasoline delivery) industry reserve in the first quarter 2007 compared to the first quarter 2006. Noninterest income of $116 million decreased $1 million from the comparable period in the prior year. Noninterest expenses of $206 million decreased $17 million from the same period in the prior year, primarily due to a $16 million decline in the provision for loan losses on lending-related commitments.

     The Western market’s net income was $66 million for the three months ended March 31, 2007 and 2006. Net interest income (FTE) of $176 million increased $8 million from the comparable prior year period. The increase in net interest income (FTE) was primarily due to a $1.9 billion increase in average loan balances (excluding Financial Services Division) and the results of the operations of the Corporation’s Financial Services Division, partially offset by a decline in loan spreads. Average low-rate Financial Services Division loan balances declined $1.3 billion in the first quarter 2007 and average Financial Services Division noninterest-bearing deposits declined $1.3 billion. The provision for loan losses increased $3 million, primarily due to an increase in average loan balances, partially offset by a decrease in certain projected loss rates. Noninterest income of $28 million for the three months ended March 31, 2007 was unchanged from the same period in the prior year as a negative $4 million warrant fair value adjustment in the first quarter 2007 was offset by nominal increases in other noninterest income categories. Noninterest expenses of $110 million increased $1 million as increases in salaries and employee benefits expense and net occupancy expense related to the addition of new banking centers were offset by decreases in various other expense categories. The Corporation opened three new banking centers in the Western market in the three months ended March 31, 2007.
     The Texas market’s net income decreased $1 million, or four percent, to $22 million for the three months ended March 31, 2007, compared to the three months ended March 31, 2006. Net interest income (FTE) of $67 million

percent ($668 million, or one percent, excluding Financial Services Division loans), to $48.9 billion in the first quarter 2007, compared to $48.6 billion in the fourth quarter 2006. Within average loans, several business lines showed growth, including the National Dealer Services (five percent), Global Corporate Banking (four percent), Private Banking (three percent), Small Business (two percent), and Middle Market (one percent) loan portfolios, from the fourth quarter 2006 to the first quarter 2007. Excluding Financial Services Division loans, average loans grew in the International Market (five percent), Western Market (four percent), Texas Market (one percent), Florida Market (one percent), and Other Markets (one percent) from the fourth quarter 2006 to the first quarter 2007. Period-end federal funds sold and securities purchased under agreements to resell decreased $1.2 billion from December 31, 2006 to March 31, 2007, as funding sources were lower at March 31, 2007.
     Management currently expects average loan growth for full-year 2007, compared to 2006, to be in the mid to high single-digit range, excluding Financial Services Division loans, with flat growth in the Midwest market and low double-digit growth in the Western and Texas markets.
     Shared National Credit Program (SNC) loans represented approximately 18 percent and 19 percent of total loans at March 31, 2007 and December 31, 2006, respectively. SNC loans are facilities greater than $20 million shared by three or more federally supervised financial institutions, which are reviewed by regulatory authorities at the agent bank level. SNC loans comprised less than one percent of total nonaccrual loans at March 31, 2007 and December 31, 2006.
     Commercial real estate loans, consisting of real estate construction and commercial mortgage loans, totaled $14.1 billion at March 31, 2007, of which $5.0 billion, or 36 percent, were to borrowers in the Commercial Real Estate lines of business.

Total deposits decreased $1.2 billion, or three percent, to $43.7 billion at March 31, 2007, from $44.9 billion at December 31, 2006, as a result of a $670 million decrease in foreign office time deposits, a $435 million decrease in money market and NOW deposits, and a $317 million decrease in noninterest-bearing deposits. Deposits in the Financial Services Division, some of which are not expected to be long-lived, decreased to $5.9 billion at March 31, 2007, from $6.5 billion at December 31, 2006. Average Financial Services Division deposits decreased $593 million, to $4.7 billion in the first quarter 2007, from $5.3 billion in the fourth

quarter 2006, in part due to the continued slowing of the real estate activity in the Western market, as well as seasonal factors. Average Financial Services Division noninterest-bearing deposits decreased $503 million, to $3.5 billion in the first quarter 2007, from $4.0 billion in the fourth quarter 2006.
     Management expects the following for full-year 2007, based upon current trends:
  Financial Services Division noninterest-bearing deposits will remain at first quarter 2007 level of $3.5 billion; and
  Average Financial Services Division loans will fluctuate with the level of noninterest-bearing deposits.

     At March 31, 2007, 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). Based on an interim decision issued by the banking regulators, the after-tax charge to shareholders’ equity associated with the adoption of SFAS No. 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an Amendment of FASB Statements No. 87, 88, 106, and 132(R),” was excluded from the calculation of regulatory capital ratios. Therefore, for purposes of calculating regulatory capital ratios, shareholders’ equity was increased by $215 million and $211 million on December 31, 2006 and March 31, 2007, respectively.
     The Corporation expects to continue active capital management in 2007 within targeted capital ratios: Tier 1 common from 6.50 percent to 7.50 percent and Tier 1 risk-based from 7.25 percent to 8.25 percent.

Risk Management
     The following updated information should be read in conjunction with the “Risk Management” section on pages 44-59 of the Corporation’s 2006 Annual Report.
Credit Risk
Allowance for Credit Losses and Nonperforming Assets
     The allowance for credit losses is the combined allowance for loan losses and allowance for credit losses on lending-related commitments. The allowance for loan losses represents management’s assessment of probable losses inherent in the Corporation’s loan portfolio. The allowance provides for probable losses that have been identified with specific customer relationships and for probable losses believed to be inherent in the loan portfolio, but that have not been specifically identified. Internal risk ratings are assigned to each business loan at the time of approval and are subject to subsequent periodic reviews by the Corporation’s senior management. The Corporation performs a detailed quarterly credit quality review on both large business and certain large personal purpose consumer and residential mortgage loans that have deteriorated below certain levels of credit risk, and may allocate a specific portion of the allowance to such loans based upon this review. The Corporation defines business loans as those belonging to the commercial, real estate construction, commercial mortgage, lease financing and international loan portfolios. A portion of the allowance is allocated to the remaining business loans by applying projected loss ratios, based on numerous factors identified below, to the loans within each risk rating. In addition, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios, including portfolio exposures to automotive, contractor, technology-related, entertainment, air transportation and retail trade (gasoline delivery) industries, real estate, and Small Business Administration loans. The portion of the allowance allocated to all other consumer and residential mortgage loans is determined by applying projected loss ratios to various segments of the loan portfolio. Projected loss ratios incorporate factors such as recent charge-off experience, current economic conditions and trends and past due and nonaccrual trends. These loss ratios are supported by underlying analysis, including information on migration and loss given default studies from each of the three largest geographic markets (Midwest, Western and Texas), as well as mapping to bond tables.
     Actual loss ratios experienced in the future may vary from those projected. 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 projected loss ratios or identified industry specific risks. A portion of the allowance is maintained 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 include the inherent imprecision in the risk rating system and the risk associated with new customer relationships. The allowance associated with the margin for inherent imprecision covers probable loan losses as a result of an inaccuracy in assigning risk ratings or stale ratings which may not have been updated for recent negative trends in particular credits. The allowance due to new business migration risk is based on an evaluation of the risk of rating downgrades associated with loans that do not have a full year of payment history.
     The total allowance for loan losses is available to absorb losses from any segment within the 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. At March 31, 2007, the total allowance for loan losses was $500 million, an increase of $7 million from $493 million at December 31, 2006. The increase resulted primarily from an increase in specific and industry reserves for customers in the retail trade (gasoline delivery) industry, partially offset by the reduction of the projected loss rates for the Corporation’s Texas and Western Markets due to continued strong metrics. The allowance for loan losses as a percentage of total period-end loans was 1.04 percent at both March 31, 2007 and December 31, 2006.
     The Corporation also 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, which is included in “accrued expenses and other liabilities” on the consolidated balance sheets. Lending-related commitments for which it is probable that the commitment will be drawn (or sold) are reserved with the same projected loss rates as loans, or with specific reserves. In general, the probability of draw is considered certain once the credit becomes a watch list credit (generally consistent with regulatory defined special mention, substandard and

39


Table of Contents

doubtful credits). Non-watch list credits have a lower probability of draw, to which standard loan loss rates are applied. The allowance for credit losses on lending-related commitments was $21 million at March 31, 2007, a decrease of $5 million from $26 million at December 31, 2006, resulting primarily from a decrease in specific reserves related to unused commitments to extend credit to customers in the automotive industry due to sales of these unfunded commitments and improvements in the associated market values. Unfunded lending-related commitments of $60 million and $52 million were sold in the three months ended March 31, 2007 and 2006, respectively.
     Nonperforming assets at March 31, 2007 were $233 million, compared to $232 million at December 31, 2006, an increase of $1 million, or less than one percent. The allowance for loan losses as a percentage of nonperforming assets increased to 214 percent at March 31, 2007, from 213 percent at December 31, 2006. Although nonperforming assets increased, they remain low by historical standards.

     Loans with balances greater than $2 million transferred to nonaccrual status were $69 million in the first quarter 2007, an increase of $3 million from $66 million in the fourth quarter 2006. The largest transfer to nonaccrual in the first quarter 2007 was a single Michigan lending relationship classified in the retail trade industry (gasoline delivery) which resulted in $48 million of transfers to nonaccrual and $10 million of net loan charge-offs ($8 million commercial mortgage and $2 million commercial), with $38 million remaining in nonaccrual loans at March 31, 2007 ($30 million commercial mortgage and $8 million commercial). The commercial mortgage balance was from loans secured by owner-occupied real estate.

     Net loan charge-offs for the first quarter 2007 were $16 million, or 0.13 percent of average total loans, compared to $22 million, or 0.18 percent, for the fourth quarter 2006. Total net credit-related charge-offs for the first quarter 2007 were $19 million, or 0.16 percent of average total loans, compared to $23 million, or 0.19 percent, for the fourth quarter 2006. The carrying value of nonaccrual loans as a percentage of contractual value was 73 percent at March 31, 2007, compared to 71 percent at December 31, 2006 and 53 percent at March 31, 2006. The increase in carrying value of nonaccrual loans as a percentage of the contractual value from a year ago reflects a stronger focus in recent years on exiting under-collateralized loan relationships prior to the loan reaching nonaccrual status, either through secondary debt market sales or aggressively encouraging those borrowers to find other sources of financing.

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 actively manages its exposure to interest rate risk. The Corporation frequently evaluates net interest income under various balance sheet and interest rate scenarios, 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, different from those management included in its simulation analyses, whether domestically or internationally, could translate into a materially different interest rate environment than currently expected. Management evaluates “base” net interest income under what is believed to be the most likely balance sheet structure and interest rate environment. The most likely interest rate environment is derived from management’s forecast for the next 12 months. This “base” net interest income is then evaluated against non-parallel interest rate scenarios that increase and decrease 200 basis points (but not lower than zero percent) from the most likely rate environment. Since movement is from the most likely rate environment, actual movement from the current rates may be more or less than 200 basis points. For this analysis, the rise or decline in interest rates occurs in a linear fashion over four months. In addition, adjustments to asset prepayment levels, yield curves and overall balance sheet mix and growth assumptions are made to be consistent with each interest rate environment. These assumptions are inherently uncertain and, as a result, the model cannot 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 interest rate changes and changes in market conditions and management strategies, among other factors. However, the model can indicate the likely direction of change. Derivative instruments entered into for risk management purposes are included in these analyses.
     The table below as of March 31, 2007 and December 31, 2006 displays the estimated impact on net interest income during the next 12 months as it relates to the most likely scenario results from the 200 basis point non-parallel shock as described above.
                                 
    March 31, 2007   December 31, 2006
(in millions)   Amount   %   Amount   %
 
Change in Interest Rates:
                               
+200 basis points
  $ 66       3 %   $ 55       3 %
-200 basis points
    (74 )     (4 )     (72 )     (4 )
 
     Corporate policy limits adverse change to no more than five percent of management’s most likely net interest income forecast and the Corporation is operating within this policy guideline.
     In addition to the analysis described above, which assumes the rise or decline in interest rates occurs in a linear fashion over four months, the Corporation also considers alternative scenarios, including an analysis reflecting a common industry practice of assuming the rise or decline in interest rates occurs in a linear fashion over 12 months. This 12-month linear scenario approach for +200 and -200 basis point non-parallel shocks resulted in an estimated impact on net interest income during the next 12 months of 1 percent and (2) percent, respectively, at March 31, 2007.
     The Corporation also performs an economic value of equity analysis 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 market value impact of rate movements upon the assets and liabilities. The economic value of equity is then calculated as the residual necessary to re-balance the resulting assets and liabilities. The market value change in the economic value of equity is then compared to the corporate policy guideline limiting such adverse change to 10 percent of the base economic value of equity as a result of a parallel 200 basis point increase or decrease in interest rates. The Corporation is operating within this policy parameter. As with net interest income shocks, a variety of alternative scenarios are performed to measure the impact on economic value of equity, including, but not limited to, changes in balance sheet structure and yield curve twists.
     The table below as of March 31, 2007 and December 31, 2006 displays the estimated impact on the economic value of equity during the next 12 months from the 200 basis point parallel increase or decrease in interest rates as described above. The change in the economic value of equity from December 31, 2006 to March 31, 2007 was primarily driven by the issuance of $515 million of 6.576% subordinated notes due 2037, which accounted for

three percentage points of the five percentage point decline under the 200 basis point parallel decrease in interest rates scenario in the table below.

Other Market Risks
     At March 31, 2007, the Corporation had an $85 million portfolio of indirect (through funds) private equity and venture capital investments, and had commitments of $42 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 reported in other assets. The investments are individually reviewed for impairment on a quarterly basis, by comparing the carrying value to the estimated fair value. Approximately $13 million of the underlying equity and debt (primarily equity) in these funds are to companies in the automotive industry. The automotive-related positions do not represent a majority of any one fund’s investments, and therefore, the exposure related to these positions is mitigated by the performance of other investment interests within the fund’s portfolio of companies.
     The Corporation holds a portfolio of approximately 790 warrants for generally non-marketable equity securities. These warrants are primarily from high technology, non-public companies obtained as part of the loan origination process. As discussed in Note 1 to the consolidated financial statements in the Corporation’s 2006 Annual Report, warrants that have a net exercise provision embedded in the warrant agreement are required to be accounted for as derivatives and recorded at fair value. The value of all warrants that are carried at fair value ($22 million at March 31, 2007) is at risk to changes in equity markets, general economic conditions and other factors. The majority of new warrants obtained as part of the loan origination process no longer contain an embedded net exercise provision.
     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 securities. Other components of noninterest income, primarily brokerage fees, are at risk to changes in the level of market activity.
     For further discussion of market risk, see Note 10 to these consolidated financial statements and pages 52-59 in the Corporation’s 2006 Annual Report.
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 2006 Annual Report, as updated in Note 1 to the unaudited consolidated financial statements in this report. These policies require numerous estimates and strategic or economic assumptions, which may prove inaccurate or subject to variations. Changes in underlying factors, assumptions or estimates could have a material impact on the Corporation’s future financial condition and results of operations. The most critical of these significant accounting policies are the policies for allowance for credit losses, pension plan accounting, income taxes and valuation methodologies. These policies are reviewed with the Audit Committee of the Corporation’s Board of Directors and are discussed more fully on pages 60-64 of the Corporation’s 2006 Annual Report. As of the date of this report, the Corporation does not believe that there has been a material change in the nature or categories of its critical accounting policies or its estimates and assumptions from those discussed in its 2006 Annual Report, aside from certain refinements to estimates and assumptions related to the January 1, 2007 adoption of FIN 48 and FSP 13-2 as described in Note 6 to these consolidated financial statements.

Other Matters
     On March 6, 2007, the Corporation announced plans to relocate its corporate headquarters to Dallas, Texas. The relocation is expected to occur by the end of the third quarter of 2007. Costs associated with the headquarters move are expected to be about $15 to $20 million over three years, with approximately $10 million expected to be incurred in 2007. In addition, Comerica Bank, a subsidiary of the Corporation, has applied to convert its banking charter from a state charter to a national charter.
Supplemental Information
     Beginning in the first quarter 2007, the Corporation assigned to the segments the portion of the allowance for loan losses maintained to capture probable losses due to the inherent imprecision in the risk rating system and new business migration risk. This portion of the allowance was previously included in the Other category. In addition, the Corporation changed its method of allocating corporate overhead. Corporate overhead is assigned 50 percent based on the ratio of the segment’s noninterest expenses to total noninterest expenses incurred by all segments and 50 percent based on the ratio of the segment’s attributed equity to total attributed equity of all segments. Formerly, corporate overhead was allocated 100 percent based on noninterest expenses. Prior periods have been restated to reflect these changes. For informational purposes, business and market segment summary net income and financial results for the years ended December 31, 2006 and 2005 have been updated to reflect these changes and are presented in the following tables.

ITEM 4. Controls and Procedures
(a)   Evaluation of Disclosure Controls and Procedures. 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 such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) 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 in ensuring 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.
(b)   Changes in Internal Controls. During the period to which this report relates, there have not been any changes in the Corporation’s internal controls over financial reporting that have materially affected, or that are reasonably likely to materially affect, such controls.
